[0016] The beneficial effects of the present invention are as follows: 1. The material recycling device of a plastic injection molding machine described in the present invention utilizes a guide component to transport different types of waste to different recycling bins, which is convenient for the subsequent transportation and use of the waste. In addition, the distribution range and the dropping range of the waste on the conveyor belt can be accurately controlled. The waste dropping range is adapted to the size of the recycling bin, and the waste will not fall outside the recycling bin. In addition, compared with the method of setting the waste dropping range too small, this method of adapting the dropping range to the opening size of the recycling bin ensures the collection speed of the recycling bin to the greatest extent, improves the overall waste recycling efficiency, and the waste can be evenly dropped to various positions in the inner cavity of the recycling bin by driving the telescopic conveyor belt body to retract, thereby avoiding the waste being concentrated in the same place in the recycling bin, so that the space of the recycling bin cannot be fully utilized, and even the waste overflows into other recycling bins.

[0017] 2. The material recycling device of a plastic injection molding machine described in the present invention can form a rectangular range under the cooperation of material plate 1, material plate 2, material plate 3, material plate 4 and the inner wall of the recycling box. When the waste falls through the end of the conveyor belt, it will first fall into the rectangular range. Even if the waste is offset due to the collision with the recycling box, it is only concentrated in the rectangular range. When the waste is stable, the orientation of the rectangular range is changed, and the above operation is repeated. The interior of the recycling box is divided into multiple unloading areas by using the rectangular range. After the waste in each unloading area is stable, material plate 1, material plate 2, material plate 3, and material plate 4 are moved again, which not only ensures that the waste can fall evenly into various positions in the recycling box, but also prevents the waste from falling into the recycling box. The impact with the inner wall of the recycling bin causes the waste to slip and move away from the original falling point, but the waste still accumulates in the same place. Moreover, every time the waste in a material unloading area becomes still, part of the waste will be at the edge of the recycling bin. The material plates one and two can be driven to move so that the material plates one and two can push the waste close to the edge of the recycling bin away from the edge of the recycling bin. This can avoid the waste from falling from the edge of the recycling bin to the outside of the recycling bin due to its close proximity to the edge of the recycling bin to a certain extent. Moreover, no matter which edge of the recycling bin the waste is close to, the waste can be kept away from the edge of the recycling bin by changing the positions of the material plates one, two, three, and four.

[0018] 3. The material recovery device of a plastic injection molding machine described in the present invention utilizes a displacement auxiliary component. When the waste material moves to the material guide plate, multiple worm gears and guide wheels rotate simultaneously. When the guide wheel rotates, it can promote the waste material to move toward the end of the material guide plate, thereby avoiding the situation where the waste material is stuck at the material guide plate and cannot move normally with the conveyor belt due to the large friction between the waste material and the material guide plate.

[0030] Specifically, when the recycling device of the existing plastic injection molding machine is in use, although the waste can be pushed out, which is convenient for the staff to operate, but in some cases, the waste in the plastic injection molding machine is divided into different types, and in order to facilitate the subsequent transportation and use, different recycling boxes are needed to collect different wastes. However, in the prior art, after the waste is pushed out, it is inconvenient to distribute the waste to different recycling boxes according to the type of the waste, thereby affecting the subsequent transportation and use of different types of waste; Therefore, in order to solve the above problems, when the present embodiment is used, the frame 3 is connected to the waste discharge port of the plastic injection molding machine, and multiple recycling boxes for receiving the waste are placed on the placement table 2, and one side of the recycling box is against the side of the placement table 2, and then the motor 8 31 drives the bidirectional threaded rod 1 25 to rotate, so that the two clamping blocks 32 slide simultaneously and approach each other, and the multiple recycling boxes are clamped; Since different types of waste materials in the plastic injection molding machine are stored in different areas, when a certain type of waste material needs to be collected, this type of waste material is first discharged to the conveyor belt surface of the telescopic conveyor belt main body 4, and then the conveyor belt is driven to operate to move the waste material to the end of the conveyor belt. At this time, according to the opening size of the recycling box for receiving the waste material as needed, the motor 5 27 is used to drive the bidirectional threaded rod 26 to rotate, so that the two guide plates 9 move in different directions at the same time, and the spacing between the two guide plates 9 is adjusted so that the shortest spacing between the two guide plates 9 is equal to the width of the recycling box opening. At the same time, the motor 6 28 drives the threaded rod 1 7 to rotate, so that the slide plate 5 slides laterally on the slide rod 1 6 until the ends of the two guide plates 9 are aligned with the edges on both sides of the recycling box opening. When the waste material moves with the conveyor belt, it will be gathered to the narrowest part of the two guide plates 9 under the action of the inclined surfaces of the two guide plates 9. At the same time, since the telescopic conveyor belt main body 4 has the telescopic characteristic, Therefore, the dropping position of the waste can be adjusted so that the waste can be accurately dropped into the designated recycling bin, and then the above operation can be repeated to transport different types of waste to different recycling bins, which is convenient for the subsequent transportation and use of the waste. Moreover, the distribution range and dropping range of the waste on the conveyor belt can be accurately controlled, and the dropping range of the waste is adapted to the size of the recycling bin, so that the waste will not fall outside the recycling bin. Moreover, compared with the method of setting the dropping range of the waste too small, this method of adapting the dropping range to the opening size of the recycling bin ensures the collection speed of the recycling bin to the greatest extent, improves the overall waste recycling efficiency, and the waste can be evenly dropped to various positions in the inner cavity of the recycling bin by driving the telescopic conveyor belt body 4 to retract, thereby avoiding the situation that the space of the recycling bin is not fully utilized due to the waste being concentrated in the same place in the recycling bin, and even the waste overflows into other recycling bins. Although the waste can be evenly distributed in the recycling bin by changing the direction in which the waste falls, when the waste falls into the recycling bin, it will impact the inner wall of the recycling bin, causing the waste to slip, making the waste move away from the original falling point. The waste may still accumulate in the same place. Therefore, in order to avoid this situation, since the material plate 14 is plugged into the material plate 2 15, when the distance between the two guide plates 9 is adjusted, the material plate 14 and the material plate 2 15 will also slide relative to each other, which is also matched with the size of the recycling bin, and then the motor 4 21 drives the threaded rod 3 22 to rotate. The material sheet 1 14 and the material sheet 2 15 are simultaneously lowered in a moving manner, so that the two are extended into the recycling box and contact with the bottom of the recycling box. At the same time, the motor 3 17 drives the threaded rod 2 19 to rotate, so that the lifting rod 20 moves downward, and the material sheet 3 23 and the material sheet 4 24 are also extended into the recycling box, and the material sheet 4 24 is in contact with the inner wall of the recycling box. At this time, with the cooperation of the material sheet 1 14, the material sheet 2 15, the material sheet 3 23, the material sheet 4 24, and the inner wall of the recycling box, a rectangular range is formed. When the waste falls through the end of the conveyor belt, it will first fall into the rectangular range. Even if the waste is deviated due to the collision with the recycling box, The waste is moved and only concentrated in the rectangular range. When the waste is stable, the orientation of the rectangular range is changed, and the above operation is repeated. The interior of the recycling box is divided into multiple unloading areas using the rectangular range. After the waste in each unloading area is stable, the material plate 14, the material plate 2 15, the material plate 3 23, and the material plate 4 24 are moved again, which not only ensures that the waste can be evenly dropped into various positions in the recycling box, but also prevents the waste from slipping due to the impact with the inner wall of the recycling box when the waste falls into the recycling box, so that the waste is far away from the original falling point, and the waste is still piled up in the same place. In addition, every time After the waste in a material unloading area becomes still, part of the waste will be at the edge of the recycling bin. The material sheet 1 14 and the material sheet 2 15 can be driven to move so that the material sheet 1 14 and the material sheet 2 15 can push the waste near the edge of the recycling bin and keep it away from the edge of the recycling bin. This can avoid the waste from falling from the edge of the recycling bin to the outside of the recycling bin due to its proximity to the edge of the recycling bin to a certain extent. Moreover, no matter which edge of the recycling bin the waste is close to, the waste can be kept away from the edge of the recycling bin by changing the positions of the material sheet 1 14, the material sheet 2 15, the material sheet 3 23 and the material sheet 4 24.

[0031] In this embodiment, Figure 6 As shown, a displacement auxiliary component is also provided on the guide plate 9; The displacement auxiliary component includes a plurality of guide wheels 10 which are arranged transversely and rotatably disposed on the guide plate 9 , and a worm gear 13 is fixedly connected to one end of the guide wheel 10 .

[0032] A worm 11 is rotatably provided at both ends of the guide plate 9 . The worm 11 is provided with a plurality of worm teeth. The plurality of worm teeth on the worm 11 mesh with a plurality of worm wheels 13 .

[0033] A second motor 12 is fixedly connected to one side of the upper end of the guide plate 9 , and an output end of the second motor 12 is fixedly connected to one end of the worm 11 .

[0034] Specifically, since the distribution range of the waste on the conveyor belt is changed by the inclined surface of the guide plate 9, the waste will contact the inclined surface of the guide plate 9. When the friction between the waste and the guide plate 9 is large, the waste will be stuck at the guide plate 9 and cannot move normally with the conveyor belt. Therefore, in order to avoid this situation, the motor 12 is used to drive the worm 11 to rotate, so that multiple worm gears 13 and guide wheels 10 can rotate at the same time. When the guide wheel 10 rotates, it can promote the waste to move to the end of the guide plate 9, thereby avoiding the situation where the waste is stuck at the guide plate 9 and cannot move normally with the conveyor belt due to the large friction between the waste and the guide plate 9.

[0035] Working principle: the frame 3 is connected to the waste discharge port of the plastic injection molding machine, and multiple recycling boxes for receiving the waste are placed on the placement table 2, and one side of the recycling box is against the side of the placement table 2, and then the motor 8 31 drives the bidirectional threaded rod 1 25 to rotate, so that the two clamping blocks 32 slide simultaneously and approach each other to clamp the multiple recycling boxes; because different types of waste in the plastic injection molding machine are stored in different areas, when a certain type of waste needs to be collected, this type of waste is first discharged to the conveyor belt surface of the telescopic conveyor belt body 4, and then The conveyor belt is driven to operate, so that the waste moves to the end of the conveyor belt. At this time, according to the opening size of the recycling box for receiving the waste as needed, the motor 5 27 is used to drive the bidirectional threaded rod 26 to rotate, so that the two guide plates 9 move in different directions at the same time, and the spacing between the two guide plates 9 is adjusted so that the shortest spacing between the two guide plates 9 is equal to the width of the recycling box opening. At the same time, the motor 6 28 drives the threaded rod 1 7 to rotate, so that the slide plate 5 slides laterally on the slide rod 1 6 until the ends of the two guide plates 9 are aligned with the edges of the two sides of the recycling box opening, and the waste is transported to the recycling box. When the conveyor belt moves, it will gather to the narrowest part of the two guide plates 9 under the action of the inclined surfaces of the two guide plates 9. At the same time, since the telescopic conveyor belt body 4 has the telescopic characteristics, the dropping position of the waste can be adjusted so that the waste can be accurately dropped into the designated recycling box, and then the above operation can be repeated to transport different types of waste to different recycling boxes, which is convenient for the subsequent transportation and use of the waste. In addition, the distribution range and dropping range of the waste on the conveyor belt can be accurately controlled, and the waste dropping range is adapted to the size of the recycling box, so that there will be no waste. In addition, compared with the method of setting the waste drop range too small, this method of matching the drop range with the size of the recycling box opening ensures the collection speed of the recycling box for the waste to the greatest extent, improves the overall waste recycling efficiency, and can drive the telescopic conveyor belt body 4 to extend and retract, so that the waste can be evenly dropped to various positions in the recycling box cavity, avoiding the waste being concentrated in the same place in the recycling box, so that the space of the recycling box cannot be fully utilized, and even the waste overflows into other recycling boxes;Although the waste can be evenly distributed in the recycling bin by changing the direction in which the waste falls, when the waste falls into the recycling bin, it will impact the inner wall of the recycling bin, causing the waste to slip, making the waste move away from the original falling point. The waste may still accumulate in the same place. Therefore, in order to avoid this situation, since the material plate 14 is plugged into the material plate 2 15, when the distance between the two guide plates 9 is adjusted, the material plate 1 14 and the material plate 2 15 will also slide relative to each other, which is also matched with the size of the recycling bin. Then, the motor 4 21 drives the threaded rod 3 22 to rotate, so that the material plate 1 14 and the material plate 2 15 are simultaneously lowered, so that both extend into the recycling bin and contact with the bottom of the recycling bin. At the same time, the motor 3 17 drives the The movable threaded rod 21 rotates to move the lifting rod 20 downward, and the material plate 3 23 and the material plate 4 24 also extend into the recycling box, and the material plate 4 24 fits with the inner wall of the recycling box. At this time, with the cooperation of the material plate 1 14, the material plate 2 15, the material plate 3 23, the material plate 4 24, and the inner wall of the recycling box, a rectangular range is formed. When the waste falls through the end of the conveyor belt, it will first fall into the rectangular range. Even if the waste is offset due to the collision with the recycling box, it is only concentrated in the rectangular range. When the waste is stable, the orientation of the rectangular range is changed, and the above operation is repeated. The interior of the recycling box is divided into multiple unloading areas using the rectangular range. After the waste in each unloading area is stable, the material plate 1 14, the material plate 2 15, the material plate 3 23, and the material plate 4 24 are moved again, It ensures that the waste can be evenly dropped into various positions in the recycling bin, and the waste will not slip due to the impact with the inner wall of the recycling bin when it falls into the recycling bin, so that the waste is far away from the original falling point, and the waste will still accumulate in the same place. Moreover, every time the waste in a material unloading area is stationary, part of the waste will be at the edge of the recycling bin, and the material plate 14 and the material plate 2 15 can be driven to move so that the material plate 14 and the material plate 2 15 can push the waste close to the edge of the recycling bin away from the edge of the recycling bin, thereby avoiding to a certain extent the situation that the waste is close to the edge of the recycling bin and falls from the edge of the recycling bin to the outside of the recycling bin. Moreover, no matter which edge of the recycling bin the waste is close to, the material plate 14 and the material plate 2 15 can be changed to move. The first 14, the second material plate 15, the third material plate 23, and the fourth material plate 24 are arranged in a manner to keep the waste away from the edge of the recycling box. Since the distribution range of the waste on the conveyor belt is changed by the inclined surface of the guide plate 9, the waste will contact the inclined surface of the guide plate 9. When the friction between the waste and the guide plate 9 is large, the waste will be stuck at the guide plate 9 and cannot move normally with the conveyor belt. Therefore, in order to avoid this situation, the motor 2 12 is used to drive the worm 11 to rotate, so that multiple worm gears 13 and the guide wheel 10 can rotate at the same time. When the guide wheel 10 rotates, it can promote the waste to move to the end of the guide plate 9, thereby avoiding the situation where the waste is stuck at the guide plate 9 and cannot move normally with the conveyor belt due to the large friction between the waste and the guide plate 9. ;

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
