Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of heat-cutting technology for plastic bag making, and more specifically, to a heat-cutting apparatus for plastic bag making. Background Technology

[0002] A plastic bag making and heat-cutting machine is a machine that makes various plastic packaging bags or other packaging bags. Generally speaking, plastic packaging bags are the main products produced. The heat-cutting bag making machine usually includes a heat-cutting blade and a conveying mechanism for transporting plastic film. When using a heat-cutting bag making machine to produce plastic packaging bags, the heat-cutting blade needs to be heated first, and then the plastic film is cut and heat-sealed by the heat-cutting blade.

[0003] When existing hot-cutting machines for making bags heat-cut plastic bags, especially during the pre-production debugging stage, plastic tends to adhere to the hot-cutting blade due to the material of the plastic bag. This affects the quality of subsequent hot-cutting of the plastic bag, thus requiring cleaning of the hot-cutting blade. The current cleaning method usually involves the operator using a scraper to scrape the plastic off the hot-cutting blade. This cleaning method is time-consuming and labor-intensive, and it is also prone to burning the operator's hands, posing a high risk. Utility Model Content

[0024] like Figures 1-4The diagram illustrates a heat-cutting apparatus for making plastic bags according to an embodiment of this disclosure. It includes a frame 1, a top frame 2, a heat-cutting blade 3, a cleaning frame 4, and a cleaning mechanism. The cleaning frame 4 is V-shaped, and its inner wall matches the blade of the heat-cutting blade 3. The top frame 2 is fixedly connected to the top of the frame 1. The heat-cutting blade 3 is slidably mounted within the top frame 2 via a lifting mechanism, which drives the heat-cutting blade 3 to move up and down for heat-cutting the plastic. The cleaning frame 4 is slidably mounted on the frame 1 via a moving mechanism, which drives the cleaning frame 4 to move in contact with the heat-cutting blade 3 for cleaning. The device is mounted on the top frame 2 and is used to scrape off the plastic scraped off the cleaning frame 4. The hot cutting blade 3 is moved up and down by the lifting mechanism, so that the hot cutting blade 3 is lowered into the cleaning frame 4. The cleaning frame 4 is then moved by the moving mechanism, so that the plastic adhering to the hot cutting blade 3 is scraped off. After that, the cleaning frame 4 is moved to the cleaning block 13, and the operator can pull the cleaning mechanism to move it, so that the plastic adhering to the cleaning frame 4 can be scraped off. Cleaning the plastic on the hot cutting blade 3 is more time-saving and labor-saving, improving cleaning efficiency while effectively preventing burns to the operator's hands.

[0025] The moving mechanism includes: sliders 5, support rods 6, and a drive assembly. Two sliders 5 are provided, each slidably mounted on the frame 1 via the sliding assembly. Support rods 6 are fixedly connected to the top of each slider 5. A cleaning frame 4 is fixedly connected between the two support rods 6. The drive assembly is located inside the frame 1 and is used to drive the two sliders 5 to move. The drive assembly includes: a drive frame 7, a drive screw 8, and a first motor 9. The drive frame 7 is fixedly connected to the bottom of the two sliders 5. The drive screw 8 is rotatably connected inside the frame 1. A screw hole is provided on the drive frame 7, and the drive screw 8 is threaded into the screw hole. The first motor 9 is installed inside the frame 1, and its output end is connected to... One end of the drive screw 8 is fixedly connected. The sliding assembly includes a slide groove 10 and a slide rod 11. The slide groove 10 is opened on the frame 1. There are two slide rods 11, and both slide rods 11 are fixedly connected in the slide groove 10. The slider 5 is slidably connected in the slide groove 10. Two guide grooves are opened on the slider 5. The two slide rods 11 are slidably connected in the guide grooves respectively. The first motor 9 drives the drive screw 8 to rotate. When the drive screw 8 rotates, it drives the drive frame 7 to move. When the drive frame 7 moves, it drives the two sliders 5 to move in the slide groove 10, thereby driving the two support rods 6 and the cleaning frame 4 to move along the hot cutting blade 3, thereby scraping off the plastic adhering to the hot cutting blade 3.

[0026] The cleaning mechanism includes a frame 12, a cleaning block 13, and a pull rod 14. One side of the cleaning block 13 has an inclined surface. The frame 12 is fixedly connected to the top of the frame 1, and the top frame 2 is fixedly connected to the top of the frame 12. The cleaning block 13 is slidably disposed in the frame 12 via a sliding assembly. The pull rod 14 is fixedly connected to one side of the cleaning block 13. By pulling the pull rod 14, the operator moves the cleaning block 13 within the frame 12, thereby scraping off and cleaning the plastic adhering to the cleaning rack 4.

[0027] The lifting mechanism includes a slide 15 and a first electric cylinder 16. Two guide grooves are provided on the top frame 2. The two ends of the slide 15 are slidably connected in the two guide grooves respectively. The slide 15 is slidably connected in the top frame 2. The hot cutting blade 3 is fixedly connected in the slide 15. The first electric cylinder 16 is installed at the top of the top frame 2. The output end of the first electric cylinder 16 passes through the top frame 2 and is fixedly connected to the top of the slide 15. Two guide rods 17 are fixedly connected to the top of the slide 15. Two sliding holes are provided on the top frame 2. The two guide rods 17 are slidably connected in the two sliding holes respectively. The first electric cylinder 16 drives the slide 15 to descend in the top frame 2, thereby driving the hot cutting blade 3 to descend into the cleaning frame 4, so that both sides of the hot cutting blade 3 contact the inner wall of the cleaning frame 4.

[0028] The working principle is as follows: When it is necessary to clean the plastic adhering to the hot cutting blade 3, the first motor 9 drives the drive screw 8 to rotate. When the drive screw 8 rotates, it drives the drive frame 7 to move. When the drive frame 7 moves, it drives the two sliders 5 to move in the slide groove 10, which moves the cleaning frame 4 to the bottom of the hot cutting blade 3. Then, the first electric cylinder 16 drives the slide 15 to descend in the top frame 2, thereby driving the hot cutting blade 3 to descend into the cleaning frame 4, so that both sides of the hot cutting blade 3 contact the inner wall of the cleaning frame 4. Then, the first drive screw 8 continues to rotate, thereby driving the cleaning frame 4 to move, thus scraping off the plastic adhering to the hot cutting blade 3. The scraped plastic adheres to one side of the cleaning frame 4. When the cleaning frame 4 moves to the other end and contacts one side of the cleaning block 13, the operator pulls the pull rod 14 to move the cleaning block 13 in the frame 12, thereby scraping off the plastic adhering to the cleaning frame 4.

[0029] It should also be noted that when the hot cutting blade 3 is hot cutting the plastic bag, the cleaning rack 4 is located on one side inside the top frame 2. Therefore, the cleaning rack 4 will not affect the normal hot cutting operation of the hot cutting blade 3.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
