Description

Technical Field

[0001] This utility model relates to the field of packaging material production technology, and more specifically, to a scrap recycling device for plastic packaging material production. Background Technology

[0002] Plastic packaging materials refer to the materials used to manufacture packaging containers, packaging decoration, packaging printing, packaging transportation, etc., to meet the packaging requirements of products. During the production and processing of plastic packaging materials, a large amount of scrap material is generated. In order to avoid waste of scrap material, it is necessary to recycle the scrap material.

[0003] A search revealed that Chinese patent CN219073146U discloses an edge material recycling device for packaging and printing production. This structure uses a motor in a crushing mechanism to drive a rotating rod, which in turn drives a rotating roller. The rotating roller, in turn, drives a crushing blade fixedly connected to it. The rotating roller drives a drive gear, which in turn drives a driven gear meshing with it. The driven gear, in turn, drives a second rotating roller. When the edge material enters the main housing, the rotating rollers rotating in the opposite direction tear the edge material, thus improving the collection of the edge material.

[0004] However, in actual use, the crushing mechanism of this structure is located inside the main box. During the crushing and recycling of edge materials, if there are incompletely crushed edge materials wrapped around the crushing blades on the crushing mechanism, it is not convenient to clean and maintain them, which can easily affect the operation of the device. In view of this, this utility model proposes an edge material recycling device for the production of plastic packaging materials. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a scrap recycling device for the production of plastic packaging materials to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a scrap recycling device for plastic packaging material production, comprising a recycling bin, a plurality of support legs installed at the bottom of the recycling bin, two crushing rollers rotatably installed inside the recycling bin, and a servo motor fixedly installed on the outer wall of the recycling bin, one end of each of the two crushing rollers being provided with meshing gears, and the output end of the servo motor being fixedly connected to one of the crushing rollers.

[0007] It can be seen that the device uses a servo motor to drive the relative rotation of the crushing rollers in conjunction with gear transmission to complete the edge material crushing operation, and the recycling box is stably supported by support legs.

[0008] To improve crushing safety and facilitate the cleaning and maintenance of the crushing rollers, preferably, the top of the recycling box is equipped with a movable feeding structure. This movable feeding structure includes a feeding frame, which is slidably installed on the top of the recycling box. Two guide plates are provided on the inner wall of the feeding frame, respectively inclined and symmetrically distributed on the two inner walls. Two mounting slots are formed on the surface of the recycling box. A lead screw is rotatably installed inside one mounting slot, and a sliding rod is fixedly installed inside the other mounting slot. A threaded block and a slider are respectively provided on the outside of the lead screw and the slider. An adjusting block is fixedly installed at one end of the lead screw. The threaded block is outside the lead screw and threadedly connected to it. The slider is slidably connected to the outside of the sliding rod. The threaded block and the slider are fixedly installed on one side of the bottom of the feeding frame.

[0009] To control the speed at which edge material enters the feed frame, ensure orderly feeding of edge material, and improve crushing effect, preferably, an adjustable discharge structure is provided at one end of the feed frame. The adjustable discharge structure includes two support blocks, both of which are fixedly installed on one side of the top of the feed frame, and a discharge plate is rotatably installed between the two support blocks. An electric push rod is provided at the bottom of the discharge plate, and the two ends of the electric push rod are respectively hinged to the bottom of the discharge plate and the outer wall of the feed frame.

[0010] To facilitate the removal or placement of materials by operators, thereby simplifying the collection and processing of crushed scrap, preferably, a material box is slidably installed at the bottom of the inner cavity of the recycling bin. The surface of the recycling bin has an opening, and the material box is slidably connected inside the recycling bin through the opening. The surface of the material box has a groove, and two inner walls of the opening of the recycling bin have embedding grooves. An embedding block is slidably installed inside the embedding groove, and the two embedding blocks are respectively fixedly installed on both sides of the outer wall of the material box.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. By setting up a movable feeding structure, the symmetrically inclined guide plates on the inner wall of the feeding frame concentrate and guide the edge material between the two crushing rollers, ensuring efficient and precise crushing operations. Moreover, by rotating the adjusting block, the lead screw is driven to rotate, causing the threaded block and the slider to move along the lead screw and the slider respectively, realizing the flexible movement of the feeding frame. This allows the crushing rollers to be quickly exposed when edge material gets entangled or maintenance is required, greatly improving the convenience of equipment maintenance. At the same time, the feeding frame can also effectively prevent edge material from splashing during crushing, ensuring the safety of the operating environment.

[0013] 2. By setting an adjustable discharge structure, the discharge plate is driven to rotate between two support blocks by an electric push rod. The tilt angle of the discharge plate can be flexibly adjusted according to the speed of edge material generation. When the angle is larger, the speed at which edge material enters the feed frame can be accelerated, and when the angle is smaller, the speed is slowed down. This ensures that the edge material enters the crushing area at a suitable rate, avoiding the problem of crushing efficiency and effect affected by edge material accumulation or insufficient supply. This significantly improves the continuity and stability of edge material recycling and processing. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] As attached Figure 1-5 The plastic packaging material production edge recycling device shown includes a recycling box 1, with several support legs 2 installed at the bottom of the recycling box 1. Two crushing rollers 3 are rotatably installed inside the recycling box 1, and a servo motor 4 is fixedly installed on the outer wall of the recycling box 1. One end of each of the two crushing rollers 3 is provided with a meshing gear 5, and the output end of the servo motor 4 is fixedly connected to one of the crushing rollers 3.

[0022] Specifically, in this structure, several support legs 2 are used to support the recycling bin 1. When the scrap material from the production of plastic packaging materials enters the interior of the recycling bin 1 and falls between two crushing rollers 3, the servo motor 4 drives one of the crushing rollers 3 to rotate. With the cooperation of two meshing gears 5, the two crushing rollers 3 rotate relative to each other inside the recycling bin 1. The two crushing rollers 3 rotating relative to each other can crush and recycle the scrap material from the production of plastic packaging materials.

[0023] In this embodiment, as shown in the appendix Figure 1 , 2 As shown in Figure 4, a movable feeding structure is provided on the top of the recycling box 1. The movable feeding structure includes a feeding frame 6, which is slidably installed on the top of the recycling box 1. Two guide plates 7 are provided on the inner wall of the feeding frame 6. The two guide plates 7 are respectively inclinedly installed on the two inner walls of the feeding frame 6 and are symmetrically distributed. Two mounting grooves 8 are opened on the surface of the recycling box 1. A lead screw 9 is rotatably installed inside one mounting groove 8, and a slide rod 10 is fixedly installed inside the other mounting groove 8. A threaded block 11 and a slider 12 are respectively provided on the outside of the lead screw 9 and the slide rod 10. An adjusting block 13 is fixedly provided at one end of the lead screw 9. The threaded block 11 is outside the lead screw 9 and is threadedly connected to the lead screw 9. The slider 12 is slidably connected to the outside of the slide rod 10. The threaded block 11 and the slider 12 are fixedly installed on one side of the bottom of the feeding frame 6.

[0024] Specifically, in this structure, the feed frame 6 is used to transport the edge material to the inside of the recycling box 1 and to prevent the edge material from splashing during crushing and affecting the operators. The two symmetrical and inclined guide plates 7 on the inner wall of the feed frame 6 can ensure that the edge material is concentrated between the two crushing rollers 3 for crushing.

[0025] When there is tangled edge material on the crushing roller 3 or when the operator needs to maintain the crushing roller 3, the operator can rotate the adjusting block 13, causing the adjusting block 13 to drive the screw 9 to rotate inside the corresponding mounting groove 8. This causes the threaded block 11 to move the feed frame 6 to the rear of the recovery box 1, and drives the slider 12 to slide and guide outside the slide rod 10. After the feed frame 6 moves to the rear of the recovery box 1, the two crushing rollers 3 at the opening of the recovery box 1 can be exposed, making it convenient to clean and maintain the two crushing rollers 3. The final state is shown in the attached figure. Figure 2 As shown.

[0026] In this embodiment, as shown in the appendix Figure 1 , 2As shown in Figure 4, an adjustable discharge structure is provided at one end of the feeding frame 6. The adjustable discharge structure includes two support blocks 19. Both support blocks 19 are fixedly installed on one side of the top of the feeding frame 6, and a discharge plate 20 is rotatably installed between the two support blocks 19. An electric push rod 21 is provided at the bottom of the discharge plate 20, and the two ends of the electric push rod 21 are respectively hinged to the bottom of the discharge plate 20 and the outer wall of the feeding frame 6.

[0027] Specifically, in this structure, when recycling scrap materials used in the production of plastic packaging materials, the discharge plate 20 is placed at the discharge port of the scrap recycling machine. According to the scrap material generation speed, the electric push rod 21 drives one end of the discharge plate 20 to rotate between two support blocks 19, adjusting the tilt angle of the discharge plate 20. When the tilt angle of the discharge plate 20 is large, the scrap material can quickly enter the interior of the feed frame 6 through the discharge plate 20, while when the tilt angle of the discharge plate 20 is small, the scrap material can slowly enter the interior of the feed frame 6, ensuring that the scrap material enters the interior of the feed frame 6 at a suitable sliding speed for crushing, thereby improving crushing efficiency and crushing effect.

[0028] In this embodiment, as shown in the appendix Figure 1 , 2 As shown in Figure 5, a material box 14 is slidably installed at the bottom of the inner cavity of the recycling box 1. An opening 15 is provided on the surface of the recycling box 1. The material box 14 is slidably connected inside the recycling box 1 through the opening 15. A groove 16 is provided on the surface of the material box 14. An embedding groove 17 is provided on both inner walls of the opening 15 of the recycling box 1. An embedding block 18 is slidably installed inside the embedding groove 17. The two embedding blocks 18 are respectively fixedly installed on both sides of the outer wall of the material box 14.

[0029] Specifically, in this structure, after the edge material is crushed, it will fall into the material box 14 at the bottom of the inner cavity of the recycling box 1 for collection. The operator can pull the material box 14 out of the recycling box 1 through the pull groove 16, so that the embedding block 18 slides in the embedding groove 17, which facilitates the collection and recycling of the crushed edge material. Conversely, the material box 14 can be placed inside the recycling box 1 through the opening 15.

[0030] Working principle of this utility model:

[0031] This application provides an edge material recycling device for the production of plastic packaging materials. In actual use, the discharge plate 20 is placed at the discharge port of the machine that generates edge material. According to the speed of edge material generation, the electric push rod 21 drives the discharge plate 20 to rotate between two support blocks 19 to adjust its tilt angle. When the angle is large, the edge material slides in quickly, and when the angle is small, it enters slowly, ensuring that the edge material enters the feed frame 6 through the discharge plate 20 at a suitable speed, avoiding the impact of poor edge material entry speed on the crushing effect. At the same time, the feed frame 6 can prevent edge material from splashing during subsequent crushing.

[0032] The edge material entering the feed frame 6 is guided by two symmetrically inclined guide plates 7 and falls into the space between two crushing rollers 3 inside the recycling box 1. After the servo motor 4 is started, it drives one of the crushing rollers 3 to rotate. With the cooperation of two meshing gears 5, the two crushing rollers 3 rotate relative to each other, crushing the edge material that falls between them. If the crushing roller 3 becomes entangled with edge material or requires maintenance, the adjusting block 13 can be rotated to drive the lead screw 9 to rotate, so that the threaded block 11 drives the feed frame 6 to move backward along the slide rod 10 in the mounting groove 8, exposing the crushing roller 3 for operation. This state is shown in the attached figure. Figure 2 As shown;

[0033] The crushed scrap falls into the loading box 14 at the bottom of the inner cavity of the recycling bin 1. The loading box 14 slides into the embedding groove 17 on the inner wall of the opening 15 of the recycling bin 1 via the embedding block 18. The operator can pull the loading box 14 out of the opening 15 through the pull groove 16 to collect and recycle the crushed scrap. After collection, the loading box 14 is slid back into the recycling bin 1 through the opening 15 to reset it, waiting for the next collection.

Electrical control components not mentioned in this technical solution are not shown in the figures because they are existing technologies, and will not be described here.
