The crushed materials can be more flexibly used in injection molding or other production processes, avoiding waste of residual materials. Accordingly, the crushed materials can be put back into production as recycled materials, thereby reducing the company's demand for purchasing new source materials and further reducing pollution to the environment.

[0021] It should be noted that: the outer walls of the four sides of the shell 3 are all provided with inspection openings.

[0022] Embodiment 2. On the basis of embodiment 1, the interior of the shell 3 is located on both sides of the collecting box 5 and is fixedly connected with a support seat 10. The interior of the support seat 10 is fixedly connected with a return spring 14. The outer wall of the top of the return spring 14 is fixedly connected with a U-shaped frame 13. The outer wall of the U-shaped frame 13 is slidably connected to the interior of the support seat 10. The outer wall of the top of the U-shaped frame 13 is fixedly connected to the outer wall of the bottom of the conveying box 4. The interior of the conveying box 4 is rotatably connected with a roller group 47. The outer wall of the roller group 47 is rotatably connected with a conveying plate 15. The outer wall of the conveying plate 15 is fixedly connected with a material strip plate 16. The outer wall of one end of the roller group 47 is rotatably connected with the interior of the conveying box 4. The outer wall of the roller group 47 is fixedly connected with a gear 17. The outer wall of one side of the gear 17 is meshingly connected with a connecting wheel 18. The connecting wheel 18 is rotatably connected with a support rod at the position of the axis. The outer wall of one end of the support rod is fixedly connected to the outer wall of one side of the crushing box 12. The outer wall of the connecting wheel 18 is meshingly connected with the outer wall of the gear 2 19.

[0023] By rotating the gear 17, the roller group 47 can drive the conveying plate 15 to rotate, so that the material belt plate 16 on the conveying plate 15 lifts the material inside the conveying box 4 and conveys it to the inside of the crushing box 12 for secondary crushing, thereby avoiding the difference in size of the material after crushing, while affecting the quality of the material after crushing, and also having an important impact on the subsequent processing process. Accordingly, through secondary crushing, the large particle material is further refined to make its particle size more uniform, avoiding the problem of difference in size of the material after crushing, and ensuring the stability and consistency of the quality of the residual material.

[0024] Embodiment 3, on the basis of embodiment 2, the outer wall of the crushing box 12 is slidably connected to the limiting sleeve 22, the inner part of the limiting sleeve 22 is slidably connected to the tooth seat 20, the outer wall on one side of the tooth seat 20 is meshedly connected to the outer wall of the main gear 9, the outer wall on one side of the tooth seat 20 is meshedly connected to the outer wall of the gear four 24, the outer wall of the crushing box 12 is located at the position of the limiting sleeve 22 and is fixedly connected to the T-shaped rod 38, the outer wall of one end of the limiting sleeve 22 is provided with a slide groove, the inner part of the slide groove is slidably connected to the outer wall of the T-shaped rod 38, and the outer wall on one side of the crushing box 12 is located on one side of the T-shaped rod 38 A mounting plate 35 is fixedly connected, an outer wall on one side of the mounting plate 35 is fixedly connected to an electric telescopic rod 36, an output end of the electric telescopic rod 36 is fixedly connected to an outer wall on one side of the limiting sleeve 22, an outer wall on one side of the mounting plate 35 is located above the electric telescopic rod 36 and is fixedly connected to a limiting rod 37, limiting holes 245 are provided on the outer walls on both sides of the limiting sleeve 22, limiting holes 1 39 connected to the outer walls on both sides are provided on the gear seat 20, the interior of the limiting hole 1 45 is movably plugged with the outer wall of the limiting rod 37, and the interior of the limiting hole 1 39 is movably plugged with the outer wall of the limiting rod 37.

[0025] When the electric telescopic rod 36 drives the limiting sleeve 22 to return to its original position, the limiting rod 37 can be inserted into the limiting hole 1 39 through the limiting hole 2 45 during the movement of the limiting sleeve 22, thereby limiting the limiting hole 1 39, preventing the tooth holder 20 from leaving the meshing between the gear 4 24 and the main gear 9 when the work is finished, causing the tooth holder 20 to slide downward inside the limiting sleeve 22, thereby correspondingly increasing the stability of the tooth holder 20 inside the limiting sleeve 22; By making the position of the limit hole 1 39 and the teeth on the gear seat 20 to be on the same horizontal line, the gear seat 20 drives the gear 4 24 to rotate, and the distance of each rotation is the same. Since the rotation distance is the same, when the gear seat 20 stops rotating, the position of the limit hole 1 39 and the limit hole 2 45 will always remain aligned. This alignment allows the limit rod 37 to be smoothly inserted into the interior of the limit hole 1 39, thereby achieving position fixation or limitation.

[0026] Embodiment 4, on the basis of embodiment 3, the interior of the crushing box 12 is located below the crushing rod 26 and is rotatably connected to a guide plate 27, the outer walls at both ends of the guide plate 27 are fixedly connected to a rotating shaft 23, the outer walls at both ends of the rotating shaft 23 are rotatably connected to the inner wall of the crushing box 12, the outer wall of one end of the rotating shaft 23 passes through the interior of the crushing box 12 and is fixedly connected to a gear 4 24, and discharge ports 46 are opened on the front and back sides of the crushing box 12.

[0027] By fixedly connecting the rotating shaft 23 and the guide plate 27, the guide plate 27 can be driven to rotate while the rotating shaft 23 rotates, thereby adjusting the angle of the guide plate 27, so that one side of the filter screen 28 rises, and the guide plate 27 can be driven to change the material guide, so that the crushed material can enter the melting box 6, avoiding the fixed direction of the material flow, and correspondingly increasing the flexibility of the material flow direction, so as to facilitate the guidance of materials with different processing requirements.

[0028] Embodiment 5, on the basis of embodiment 4, a filter screen 28 is fixedly connected to the inside of one side of the guide plate 27, an L-shaped slide groove 30 is provided on the outer walls on both sides of the top of the guide plate 27, the outer wall of the top of the guide plate 27 is slidably connected to a movable plate 32, the outer wall of the bottom of the movable plate 32 is fixedly connected to an L-shaped slide rod 31, the outer walls of the two L-shaped slide rods 31 are slidably connected to the inside of the L-shaped slide groove 30, square grooves 29 are provided at both ends of the top of the guide plate 27, a T-shaped magnetic rod 33 is fixedly connected to the inner wall of the square groove 29, square holes are provided at both ends of the top of the movable plate 32, a T-shaped magnetic rod 33 is movably inserted inside the square hole, and the outer wall of the T-shaped magnetic rod 33 is connected to the inner wall of the magnetic sleeve 34 with opposite poles attracting each other.

[0029] The T-shaped magnetic rod 33 can be fixed inside the square groove 29 through the attraction between the opposite poles of the T-shaped magnetic rod 33 and the magnetic sleeve 34, avoiding the filter screen 28 from filtering materials when it is not needed, and correspondingly increasing the flexibility of the use of the filter screen 28.

[0030] Embodiment 6. On the basis of embodiment 4, the outer wall on the other side of the limit sleeve 22 is fixedly connected with a push block 40, and the shape of the push block 40 is L-shaped. The outer wall on one side of the crushing box 12 is located below the push block 40 and is fixedly connected with a support plate 42. The outer wall on the top of the support plate 42 is fixedly connected with a reset spring 2 43. The outer wall on the top of the reset spring 2 43 is fixedly connected with a fixed plate 41. The outer wall at the bottom of the fixed plate 41 is movably plugged into the top of the gear 4 24. The outer wall at the bottom of the fixed plate 41 is fixedly connected with a guide rod 44. The outer wall of the guide rod 44 is slidably connected to the inside of the support plate 42.

[0031] When the push block 40 is driven to move back by the limiting sleeve 22, the guide rod 44 can be squeezed against the fixed plate 41, so that the fixed plate 41 drives the guide rod 44 to slide inside the support plate 42, and the other side of the bottom of the fixed plate 41 can be inserted above the gear four 24, so as to fix the gear four 24, thereby preventing the guide plate 27 from rotating when hit by the material. Accordingly, by fixing the gear four 24, the stability of the guide plate 27 during work can be increased, thereby improving the working efficiency of the guide plate 27.

[0032] In actual use, when working, first, when the injection molding machine body 1 produces excess material inside the mold, it will enter the crushing box 12 through the residual material recovery port 2. At this time, start the motor 8 on the L-shaped plate 7, and then through the operation of the motor 8, the main gear 9 can be driven to rotate, and then the meshing connection between the gear 2 19, the gear 3 21 and the main gear 9 can be used to drive the gear 2 19 and the gear 3 21 to move while the main gear 9 rotates. Then, through the rotation of the gear 2 19 and the gear 3 21, the crushing rod 2 26 and the crushing rod 1 25 can be driven to crush the material entering the crushing box 12. The crushed material can be more flexibly used in injection molding or other production processes again, avoiding waste of residual material. Correspondingly, the crushed material can be put back into production as recycled material, thereby reducing the company's demand for purchasing new raw materials and further reducing pollution to the environment.

[0033] The crushed material enters the guide plate 27 and is filtered by the filter screen 28 on the guide plate 27. The material with smaller particles directly passes through the filter screen 28 and enters the collection box 5 for collection so as to be processed and utilized for the second time. The material with larger particles can enter the conveying box 4 through the discharge port 46 to prepare for the second crushing of the large particles, thereby ensuring that the large particles reach the required size specifications. By setting the filter screen 28, materials of different sizes can be effectively processed to ensure that they can meet the requirements of subsequent processing or utilization.

[0034] When the material inside the conveying box 4 gradually increases, the weight of the conveying box 4 can be increased. At this time, the conveying box 4 will drive the U-shaped frame 13 to generate downward pressure on the internal return spring 14 of the support seat 10. When the return spring 14 is compressed by the pressure, the U-shaped frame 13 can drive the conveying box 4 to slide downward. Then, through the downward movement of the conveying box 4, the roller group 47 can drive the gear 17 to move downward. When the gear 17 moves downward and meshes with the connecting wheel 18, the connecting wheel 18 can drive the gear 17 to rotate. Then, by rotating the gear 17, the roller group 47 can drive the conveying plate 15 to rotate, so that the material belt plate 16 on the conveying plate 15 lifts the material inside the conveying box 4 and conveys it to the inside of the crushing box 12 for secondary crushing, thereby avoiding the difference in size of the material after crushing, while affecting the quality of the material after crushing, and also having an important impact on the subsequent processing process. Accordingly, through secondary crushing, the large particle material is further refined to make its particle size more uniform, avoiding the problem of difference in size of the material after crushing, and ensuring the stability and consistency of the quality of the residual material.

[0035] It should be noted that: the outer walls on both sides of the conveying box 4 are provided with strip bars, and the outer walls on both sides of the crushing box 12 are provided with guide grooves. The strip bars and the guide grooves are slidably connected. Through the cooperation of the strip bars and the guide grooves, the movement trajectory of the conveying box 4 can be limited while maintaining the stability of the conveying box 4 sliding on the crushing box 12.

[0036] By the operator opening the inspection door on one side of the crushing box 12, the T-shaped magnetic rod 33 can be pulled out from the inside of the square groove 29 on one side, thereby releasing the fixation of the square groove 29 to the movable plate 32. At this time, by sliding the movable plate 32, the movable plate 32 can drive the L-shaped sliding rod 31 to move inside the L-shaped sliding groove 30, thereby covering the filter screen 28. When the square hole on the movable plate 32 is aligned with the square groove 29 on the outer wall of the other side, the T-shaped magnetic rod 33 can be inserted into the inside of the square groove 29, and then the T-shaped magnetic rod 33 can be fixed inside the square groove 29 through the attraction between the opposite poles of the T-shaped magnetic rod 33 and the magnetic sleeve 34, thereby avoiding the filter screen 28 from filtering materials when the filter screen 28 is not needed, thereby correspondingly increasing the flexibility of using the filter screen 28.

[0037] It should be noted that the L-shaped chute 30 does not have a blocking plate, so that the internal materials entering the L-shaped chute 30 can slide out.

[0038] By starting the electric telescopic rod 36, and then through the movement of the electric telescopic rod 36, the limit sleeve 22 can be pushed to drive the T-shaped rod 38 to slide, and then through the movement of the limit sleeve 22, the tooth seat 20 can move accordingly. When the tooth seat 20 is meshed with the main gear 9 and the gear four 24, the movement of the electric telescopic rod 36 can be stopped. At this time, under the rotation of the main gear 9, the tooth seat 20 can be driven to move, and then through the movement of the tooth seat 20, the gear four 24 can drive the rotating shaft 23 to rotate accordingly. Through the fixed connection between the rotating shaft 23 and the guide plate 27, the guide plate 27 can be driven to rotate while the rotating shaft 23 rotates, thereby adjusting the angle of the guide plate 27, so that one side of the filter screen 28 rises, and the guide plate 27 can be driven to change the material guide, so that the crushed material enters the interior of the melting box 6, avoiding the fixed direction of the material flow, and correspondingly increasing the flexibility of the material flow direction, so as to guide the material with different processing requirements.

[0039] It should be noted that the melting box 6 is a prior art and is a device specially used to heat solid materials to a molten state.

[0040] When the limit sleeve 22 is driven to return to its original position by the electric telescopic rod 36, the limit rod 37 can be inserted into the limit hole 1 39 through the limit hole 2 45 during the movement of the limit sleeve 22 back, thereby limiting the limit hole 1 39, preventing the gear seat 20 from leaving the meshing between the gear 4 24 and the main gear 9 when finishing work, causing the gear seat 20 to slide downward inside the limit sleeve 22, thereby correspondingly increasing the stability of the gear seat 20 inside the limit sleeve 22.

[0041] It should be noted that: by making the position of the limit hole 1 39 and the teeth on the gear seat 20 to be on the same horizontal line, the gear seat 20 drives the gear 4 24 to rotate, and the distance of each rotation is the same. Since the rotation distance is the same, when the gear seat 20 stops rotating, the position of the limit hole 1 39 and the limit hole 2 45 will always remain aligned. This alignment allows the limit rod 37 to be smoothly inserted into the interior of the limit hole 1 39, thereby achieving position fixation or limitation.

[0042] When the push block 40 is driven to move back by the limiting sleeve 22, the guide rod 44 can be squeezed against the fixed plate 41, so that the fixed plate 41 drives the guide rod 44 to slide inside the support plate 42, and the other side of the bottom of the fixed plate 41 can be inserted above the gear four 24, so as to fix the gear four 24, thereby preventing the guide plate 27 from rotating when hit by the material. Accordingly, by fixing the gear four 24, the stability of the guide plate 27 during work can be increased, thereby improving the working efficiency of the guide plate 27.

[0043] It should be noted that when the limiting sleeve 22 drives the pushing block 40 to move forward, the pushing block 40 can leave the top of the fixed plate 41, thereby releasing the squeezing of the fixed plate 41. At this time, under the action of the reset spring 2 43, the fixed plate 41 can be pushed to move upward, thereby releasing the limiting effect of the fixed plate 41 on the gear 4 24.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
