A simple device for cutting plastic bottles into strips. Machine for cutting plastic bottles - how to make a homemade machine for cutting plastic bottles

Plastic bottles are lying around (or even neatly standing) literally everywhere you look. But from them, with the help of a very simple device, you can make the necessary thing - ribbon, braided rope or fishing line.

You may ask: why might such a tape be needed? Its application is very diverse due to its flexibility and strength. You can tie anything with this ribbon; it will make a convenient broom, brush, or even a door mat.

Also, a plastic “rope” will successfully replace the slats with which the film used for greenhouses and greenhouses is attached. And of course, the ribbon is suitable for interior decoration. Moreover, if you cut not a ribbon, but a thread (fishing line), it will be useful for sewing something together.

Main stages of work

Let's get started, make a simple “machine” and “unwind” the bottles like grandma’s balls. Let's prepare a saw, a jigsaw, a vice, a ruler, a pencil, a safety razor blade, self-tapping screws with a wide press washer, a wooden block 3 cm wide, 2 cm thick, 20 cm long.

Then we divide the blade into two halves. We clamp the block in a vice and make a cut with a jigsaw along the transverse line so that half of the blade fits completely into it. The second cut (in the middle) must be made first with a jigsaw from the end of the block, then with a saw, increasing the width of the gap.

Note that the second cut should go a little further through the first. Its length depends on how wide the ribbon you want to make. We sand the gap and secure the blade with self-tapping screws, which we screw in a little further than it on both sides. That’s all, actually – the design is ready.

We take a plastic bottle, cut off the bottom, insert the edge into the device, turn it slightly, making a cut in the plastic. Now we simply hold the block with one hand and pull out our tape with the other.

First, watch how to use a simple tool to cut a plastic bottle into neat strips in this video from the Science Vetal channel. Alternative developments are shown below.

Smooth strips from a PVC bottle

It is shown how to make a cutter from a block using the example of an original product presented on the SergeyTron v2.0 channel. The mechanism of operation is considered. You will need: a utility knife, a block of approximately 50 x 50 x 150 mm, a pin of at least 350 mm, two screws, two washers and a piece of 200 mm plastic pipe.
Available material is true.

Saw the block into two parts 100 millimeters and 50 millimeters long. The first will go to the cutter, and the second to the ribs.

Let's start with the pin. First, a little about its tilt. The wider the strip, the more actively the bottle moves away from the cutter. The pin should be tilted. Don't overdo it, the strip will have to be pulled with difficulty, and the cut will be bored out. If you don’t make a slope, the strip will fall on the bottom of the cut and will not become straight and will break.

You can drill the hole at an angle, straight and make a bent 4. This angle 4 trick is a must for those who want to cut a straight strip on a block cutter. This device has a slope of 7 degrees. Plastic pipe nozzle. A strip 5–10 mm wide is cut. 10 – 15 mm without nozzle. If you don’t want to suffer with the pin, then you need to make the cutters sound like bars so that you can replace the bored cuts.

This video tutorial shows how to cut a plastic bottle into even strips using a reliable tool. This cutter is about 1 year old. I made it in his master as an experimental one, but it cuts perfectly smooth and there is no need to redo it. The secrets of this miracle are that the blade is located in the middle of the cut, so that it will or will not jump before the cut. It's kind of like a guide.

I cut at an angle and adjusted the blade with nootropil to the desired tape size. The strip was cut at one end 10 mm. And on the other 9 mm.

The author made this design by accident, without calculations. But the main thing for leveling the strip is not the cutter, but the preparation of the plastic bottle before it. Take a regular A4 sheet. On one side, draw into a tape of the required size 9.5 mm. Another cutter option.

The empty container is unrolled onto a ribbon of the required width, after which it is used in this form or passed through a die to form thin tubes.

The simplest model

Organize production possible in any conditions with a minimum of components:

• wooden block with approximate dimensions 2x20x10 cm;
• metal washers 10-12 pcs. with a diameter of 20-25 mm and a thickness of 1-1.5 mm for M6 bolts;
• a pair of M6 bolts 30-35 mm long;
• two M6 nuts;
• a blade from a construction knife or from pencil shavings.

As additional elements you can buy a clamp to fix the machine and install a guide axis into the bar, equal to the height of an empty plastic bottle.

In order for this equipment worked without failures, it needs to be assembled and configured correctly.
In the wooden plank we make two holes with a diameter of 6.5 mm for bolts at a distance of approximately 27-29 mm with a washers diameter of 25 mm. This will allow you to end up with a gap of 3-4 mm between the washers.
We clamp the knife horizontally at a certain height; as a result, the distance between the blade and the wooden plank will correspond to the width of the plastic tape.
The step-by-step production process is in the photo below.

Model with cuts

Can do it yourselfmachine with cuts. A wooden or aluminum block with a cross-section of 30x30 mm and a length of 15-20 cm is suitable for it. The depth of the cut corresponds to the width of the future tape.

Materials required for work:

1. bar;
2. self-tapping screws for fastening in metal or wood;
3. stationery or construction knife;
4. threaded axle with two wing nuts.

This equipment used for manual rather than stationary work. After making the cuts, you will need to clean the resulting grooves with sandpaper or a small file/needle file.
A knife in a similar configuration is attached to the top of the block, covering the poses. To fix it, self-tapping screws are used, which are screwed through the holes in the knife blade.
The video shows a step-by-step guide to making a homemade machine for cutting plastic bottles.

The material from which PET bottles are made shrinks when heated. Thanks to this, a tape made from it can be used instead of a rope or clothes cord to firmly connect various materials, making it possible to produce various materials. Cutting ribbons with scissors is almost impossible - I made a special device for this.

Assembling a machine for cutting tape from a plastic bottle

You will need: several large washers 2 bolts with solid threads, nuts and washers a utility knife blade with a hole a piece of plywood (boards, laminate).

On the plywood platform we place 2 large washers pressed against each other (photo 1), mark their centers. We drill holes in them according to the diameter of the bolts. Then, on the back side of the platform, we make a recess in the shape of the head so that they “sink” and the bolts do not rotate around their axis (photo 2). To cut a tape of a certain width, we place so many large washers on the leg protruding from the reverse side of each bolt so that their total thickness is this width. For example, to cut a 5 mm tape you will need 3 washers with a thickness of 1.58 mm.

Place a knife blade on top and place at least one more large washer on it (photo 3). Align them and tighten the bolts with nuts. The machine is ready. We fix the platform on the table with self-tapping screws or a clamp.

Cutting tape from a plastic bottle

Remove the bottom, cut a strip and insert it under the knife. With one hand we hold the bottle and press on the cork, with the other we pull out the tape to be cut.

A two-liter bottle yields more than 25 m of tape

Important!
We position the knife blade so that the protruding part of its cutting edge is in the area of ​​the shortest distance between the washers.

How to cut tape from a plastic bottle video

For cutting tape from plastic bottles. I saw a video on the Internet where a kind of ribbon was made from an ordinary plastic bottle. The scope of its use is of course very limited.

I saw on the Internet where a kind of ribbon was made from an ordinary plastic bottle. The scope of its use is of course very limited.

Used it in the construction of a wooden fence, where it was strengthened by tightening the place of a board nailed to a horizontal beam. In winter, this section of the fence was constantly covered with a large amount of snow, as a result, many boards flew off the fence, so to speak. I used ordinary iron wire before, but it quickly rusted and became unusable. Buying galvanized is expensive. The tension in the twine weakened over time. As a result, I began to tighten plastic bottles using tape and partially melt them after tying them to secure the connection. This structure stood successfully for one winter.

The method for producing tape from plastic bottles is surprisingly simple and accessible.

You will only need two M5 bolts (no longer needed) with a length of at least 30mm, two nuts and washers for them, a wooden block or board, the blade of a stationery knife, as well as several larger washers, for example with a hole of 8 mm (their number depends on the thickness of the cut tapes).

To begin, we place large-diameter washers, in this case on a block close to each other, and mark the holes with a pencil.

We drill holes with a drill using a 5 mm drill bit.
Insert the bolts.

We insert large diameter washers in two pieces (the number depends on the thickness of the tape you need) so that there is a gap between them.

We insert the stationery knife as shown in the photo.

We put small washers in the bolts and tighten them with nuts (do not overtighten, otherwise the blade will burst).

Cut off the bottom of the bottle and make a small narrow cut in the form of a strip counterclockwise.

We insert the strip into the hole between the large washers of the cutting device and pull without jerking while holding the bottle with the other hand. I first secured the wooden block with a clamp on the table.
