Description

Technical Field

[0001] The invention relates to the technical field of POF matte high-shrinkage film waste collection, in particular to a POF matte high-shrinkage film waste collection device. Background Art

[0002] POF matte high shrink film is a packaging material with excellent performance. It has excellent high shrinkage performance and can closely fit the shape of the packaged object when heated. This film also has good flexibility and tear resistance, is not easy to break, and can effectively extend the shelf life of the product. Due to its good comprehensive performance, POF matte high shrink film is widely used in product packaging in many industries such as food, cosmetics, and daily necessities. A large amount of waste will be generated during the production and use of the film. Traditional waste collection methods mostly rely on manual collection, which is inefficient and labor-intensive, and it is difficult to meet the needs of large-scale production. POF matte high shrink film waste collection equipment can collect and process film waste in a centralized manner;

[0003] The film waste collection equipment is not ideal for crushing high-toughness and high-shrinkage films. Static electricity is easily generated during the collection process, which can easily cause the film to adhere to the surface of the component. In addition, the degree of automation of the equipment is low, so we proposed a POF matte high-shrinkage film waste collection equipment. Summary of the invention

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] For the first embodiment, please refer to Figure 1-Figure 5 The present invention is a POF matte high shrink film waste collection device, comprising a shell 1, the top of the shell 1 is connected with a feed pipe 2, the inner wall of the shell 1 is rotatably connected with a crushing device 3, the inner wall of the shell 1 below the crushing device 3 is fixedly connected with an auxiliary crushing and cleaning device 4, both sides of the shell 1 are provided with rectangular arc holes 5, the inner wall of the shell 1 is fixedly connected with a screening circulation device 6, the inner wall of the shell 1 below the screening circulation device 6 is fixedly connected with a collecting pipe 7, one side of the shell 1 is provided with a rectangular hole 8, the bottom of the inner wall of the shell 1 is slidably connected with a pull-out box 9, and one end of the screening circulation device 6 is connected with the rectangular arc hole 5;

[0026] The crushing device 3 includes a round roller 31, one end of which penetrates and is fixedly connected to a rotating rod 32, one end of which is fixedly connected to a driving shaft of a motor 33, a sharp-toothed cutter 34 is fixedly connected to the side of the round roller 31, a sawtoothed cutter 35 is fixedly connected to the side of the round roller 31, a corrugated spring sheet 36 is fixedly connected to the side of the round roller 31, and an arc-shaped rubber strip 37 is fixedly connected to the side of the round roller 31. One end of the rotating rod 32 penetrates the shell 1 and is rotatably connected to the shell 1, and the output end of the motor 33 is fixedly connected to one side of the shell 1. When in use, the POF matte high shrink film waste is put into the feed pipe 2 from the feed pipe 2. Inside the shell 1, the film is torn and broken by the breaking device 3. After the breaking is completed, the film that meets the requirements will pass through the screening circulation device 6 to enter the collection tube 7, and finally fall into the pull-out box 9. The film that does not meet the requirements is scraped in the screening circulation device 6 and re-enters the shell 1. It is broken again by the auxiliary breaking and cleaning device 4 until the film breaking degree meets the screening requirements. The film will pass through the screening circulation device 6 to enter the collection tube 7 and fall into the pull-out box 9 to complete the collection. When the film inside the pull-out box 9 is full, the operator only needs to pull the handle to easily take out the pull-out box 9. , complete the collection of the processed film waste, which is convenient and fast, and is convenient for subsequent unified processing. When the film waste enters the shell 1, the motor 33 starts to start, driving the rotating rod 32 to rotate, and the round roller 31 set and fixed on the rotating rod 32 rotates accordingly. The two round rollers 31 rotate inward at the same time, and the sharp-toothed tool 34 first punctures the film waste to make it initially divided. Then, the serrated tool 35 further squeezes and tears the film through the two relatively rotating round rollers 31. Under the synergistic action of the double tools, the film waste is gradually decomposed into small pieces. In order to prevent the film from remaining on the round rollers, On the roller 31, a corrugated spring piece 36 is fixed on the surface of the roller 31, and the corrugated spring piece 36 is arranged between the cutters. If the film remains on the surface of the corrugated spring piece 36, the roller 31 rotates to the inner side and drives the cutter to squeeze the corrugated spring piece 36 to deform it. When the corrugated spring piece 36 returns to its original state, the film attached to the surface is bounced up and falls to the bottom. An arc-shaped rubber strip 37 is arranged between the inner side of the corrugated spring piece 36 and the surface of the roller 31. The arc-shaped rubber strip 37 is fixed on the surface of the roller 31 to prevent the cutter from squeezing the corrugated spring piece 36 too much, causing the corrugated spring piece 36 to break, and to buffer the corrugated spring piece 36.

[0027] For the second embodiment, please refer to Figure 1-Figure 10The present invention provides a POF matte high shrink film waste collection device: the auxiliary crushing and cleaning device 4 includes a winding rod 41, an elastic iron sheet 42 is fixedly connected to the winding rod 41, one end of the winding rod 41 is fixedly connected to the driving shaft of the motor 43, a through hole 1 44 is provided on the inner side of the elastic iron sheet 42, a soft brush 45 is fixedly connected to the inner lower part of the elastic iron sheet 42, an arc plate 46 is penetrated and slidably connected to one side of the elastic iron sheet 42, a through hole 2 47 is provided on the inner side of the arc plate 46, a sawtooth block 48 is fixedly connected to the inner side of the arc plate 46, one end of the winding rod 41 penetrates the shell 1 and is rotatably connected to the shell 1, the output end of the motor 43 is fixedly connected to one side of the shell 1, and one side of the arc plate 46 is fixedly connected to the inner wall of the shell 1;

[0028] The screening circulation device 6 includes a round rod 61, a baffle 62 is fixedly connected to the bottom of the round rod 61, a screening mechanism 63 is arranged on one side of the baffle 62, a circulation mechanism 64 is arranged on the side of the baffle 62 away from the screening mechanism 63, the screening mechanism 63 includes an arc-shaped electric slide rail 631, a rectangular plate 632 is fixedly connected to one side of the arc-shaped electric slide rail 631, push rods 633 are fixedly connected to both sides of the rectangular plate 632, a rubber scraper 634 is fixedly connected to the bottom of the rectangular plate 632, an arc-shaped screening plate 635 is arranged on the bottom of the rubber scraper 634, a side of the arc-shaped electric slide rail 631 away from the rectangular plate 632 is fixedly connected to the inner wall of the shell 1, a side of the arc-shaped screening plate 635 is fixedly connected to the inner wall of the shell 1, and the circulation mechanism 64 includes a shrink tube 641, and the shrink tube One end of 641 is connected to a ventilation pipe 642, and a ventilation hole 643 is opened on the inner wall of the ventilation pipe 642. One side of the ventilation pipe 642 is connected to a fan 644. The end of the shrink tube 641 away from the ventilation pipe 642 is connected to the rectangular arc hole 5, and the end of the ventilation pipe 642 away from the shrink tube 641 is connected to the top of the shell 1. The bottom of the fan 644 is fixedly connected to the top of the shell 1. When in use, the broken film waste falls onto the surface of the arc-shaped sieve plate 635, and the film waste that reaches the sieve aperture passes through the arc-shaped sieve plate 635, and the film waste that does not meet the requirements remains on the surface of the arc-shaped sieve plate 635. The arc-shaped electric slide rail 631 is started, driving the rectangular plate 632 and the rubber scraper 634 fixed under the rectangular plate 632 to move, and the rubber scraper 634 will move the arc-shaped The film on the surface of the sieve plate 635 is scraped up and pushed to the rectangular arc hole 5. The push rod 633 pushes up the baffle 62, and the fan 644 is started. The suction force generated by the fan 644 sucks the film from the rectangular arc hole 5 into the contraction tube 641, and reaches the ventilation hole 643 through the ventilation pipe 642. At this time, the fan 644 is turned off, and the film falls due to gravity and re-enters the shell 1 for crushing. The film re-entering the shell 1 falls between the arc plate 46 and the round roller 31. The serrated tool 35 on the surface of the round roller 31 cooperates with the serrated block 48 on the inner surface of the arc plate 46 to squeeze the re-entering film again, so that the film is further crushed. In this process, in order to prevent the film from falling prematurely, we designed the elastic iron sheet 42, and the through hole on the elastic iron sheet 42 The positions of through hole 1 44 and through hole 2 47 on the surface of arc plate 46 are staggered in the initial state, so that the film cannot fall. At the same time, the round roller 31 will contact the soft brush 45 on the inner side and lower side of the elastic iron sheet 42 during rotation. The soft brush 45 can clean the sharp-toothed cutter 34 and the sawtooth cutter 35 on the surface of the round roller 31 to ensure the sharpness and cleanliness of the cutter and maintain the crushing effect. When the film is crushed, the driving shaft of the motor 43 starts to rotate, driving the winding rod 41 to rotate. The rotation of the winding rod 41 will roll up the elastic iron sheet 42 along its surface. As the elastic iron sheet 42 rotates, the position of through hole 1 44 gradually coincides with through hole 2 47. At this time, the film can fall smoothly. The film after falling will be screened by the arc-shaped screening plate 635 again.If the film meets the screening requirements, it will pass through the curved screening plate 635 and enter the drawer box 9. Otherwise, the above process will be repeated until the film is broken to meet the screening requirements.

[0029] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.

[0030] When the present invention is operated and used, the POF matte high shrink film waste is put into the shell body 1 from the feed pipe 2, and the film is torn and broken by the breaking device 3. After the breaking is completed, the film that meets the requirements will pass through the screening circulation device 6 to enter the collection pipe 7, and finally fall into the pull-out box 9. The film that does not meet the requirements is scraped up in the screening circulation device 6 and re-enters the shell body 1, and is broken again by the auxiliary breaking and cleaning device 4 until the film breaking degree meets the screening requirements. The film will then pass through the screening circulation device 6 to enter the collection pipe 7 and fall into the pull-out box 9 to complete the collection. When the film inside the pull-out box 9 is full of collected films, the operator only needs to pull the handle to easily take out the pull-out box 9, and complete the collection of the processed film waste. It is convenient and fast, and is easy for subsequent unified processing. When the film waste enters the shell 1, the motor 33 starts to start, driving the rotating rod 32 to rotate, and the round roller 31 mounted and fixed on the rotating rod 32 rotates accordingly. The two round rollers 31 rotate inward at the same time, and the sharp-toothed tool 34 first punctures the film waste to make it initially divided. Then, the serrated tool 35 further squeezes and tears the film through the two relatively rotating round rollers 31. Under the synergistic action of the double tools, the film waste is gradually decomposed into small pieces. In order to prevent the film from remaining on the round roller 31, a corrugated spring piece 36 is fixed on the surface of the round roller 31. The corrugated spring piece 36 is set between the tools. If the film remains on the surface of the corrugated spring piece 36, the round roller 31 rotates to the inside and drives the tool The corrugated spring piece 36 is squeezed to deform it. When the corrugated spring piece 36 returns to its original shape, the film attached to the surface is bounced up and falls to the bottom. An arc-shaped rubber strip 37 is arranged between the inner side of the corrugated spring piece 36 and the surface of the round roller 31. The arc-shaped rubber strip 37 is fixed to the surface of the round roller 31 to prevent the tool from squeezing the corrugated spring piece 36 too much, so that the corrugated spring piece 36 is broken, and the corrugated spring piece 36 is buffered. The broken film waste falls onto the surface of the arc-shaped sieve plate 635. The film waste that meets the sieve aperture passes through the arc-shaped sieve plate 635, and the film waste that does not meet the requirements remains on the surface of the arc-shaped sieve plate 635. The arc-shaped electric slide rail 631 is started to drive the rectangular plate 632 and the rubber scraper 634 fixed under the rectangular plate 632 to move. The rubber scraper 634 is moved. 34 scrapes up the film on the surface of the arc sieve plate 635 and pushes it to the rectangular arc hole 5. The push rod 633 pushes up the baffle 62, and the fan 644 is started. The suction force generated by the fan 644 sucks the film from the rectangular arc hole 5 into the contraction tube 641, and reaches the ventilation hole 643 through the ventilation pipe 642. At this time, the fan 644 is turned off, and the film falls due to gravity and re-enters the shell 1 for crushing. The film re-entering the shell 1 falls between the arc plate 46 and the round roller 31. The serrated cutter 35 on the surface of the round roller 31 cooperates with the serrated block 48 on the inner surface of the arc plate 46 to squeeze the re-entering film again, so that the film is further crushed. In this process, in order to prevent the film from falling prematurely, we designed the elastic iron sheet 42.The through hole 1 44 on the elastic iron sheet 42 and the through hole 2 47 on the surface of the arc plate 46 are staggered in the initial state, so that the film cannot fall. At the same time, the round roller 31 will contact the soft brush 45 on the inner side and lower side of the elastic iron sheet 42 during the rotation process. The soft brush 45 can clean the sharp tooth tool 34 and the sawtooth tool 35 on the surface of the round roller 31 to ensure the sharpness and cleanliness of the tool and maintain the crushing effect. When the film is crushed, the driving shaft of the motor 43 starts to rotate, driving the winding rod 41 to rotate. The rotation of the winding rod 41 will roll up the elastic iron sheet 42 along its surface. As the elastic iron sheet 42 rotates, the position of the through hole 1 44 gradually coincides with the through hole 2 47. At this time, the film can fall smoothly. The film after falling will be screened by the arc sieve plate 635 again. If it meets the screening requirements, it will enter the pull-out box 9 through the arc sieve plate 635. Otherwise, the above-mentioned entire process will be repeated until the degree of film crushing meets the screening requirements.

[0031] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
