Description

Technical Field

[0001] The present invention relates to the technical field of recycling of molded waste, and particularly to a device for recycling pulp molded waste. Background Art

[0002] Molded waste is the waste material generated during the molding process of plastic products. In the molding production process, in process links such as injection molding, blow molding, and compression molding, waste will occur due to various factors. In order to save costs, these molded wastes can be recycled. When recycling, the wood-plastic waste needs to be crushed and pulped, and at this time, a recycling and reuse device is required to complete the crushing and pulping of the molded waste.

[0003] Although the existing device can crush the molded waste through the crushing roller, its crushing structure is single, and the crushing effect on large wood-plastic wastes is not thorough enough, which affects the subsequent pulping; the crushing structure of the existing device is not fine enough, and it cannot screen the waste fragments after crushing and re-crush the large waste after crushing, which affects the subsequent pulping. Summary of the Invention

[0004] The present invention relates to a device for recycling pulp molded waste, and solves the problems that although the existing device can crush the molded waste through the crushing roller, its crushing structure is single, the crushing effect on large wood-plastic wastes is not thorough enough, which affects the subsequent pulping; the crushing structure of the existing device is not fine enough, and it cannot screen the waste fragments after crushing and re-crush the large waste after crushing, which affects the subsequent pulping.

[0005] The present invention provides a device for recycling pulp molded waste, which specifically includes: a crushing box; a crushing component is arranged in the crushing box, the crushing component includes two crushing rollers rotatably connected to the crushing box, the two crushing rollers are engaged with each other, a first gear is welded on the rotating shaft of each crushing roller, and the two first gears are meshed; a seat body is welded at the left end of the crushing box, the seat body is of an L-shaped structure, and a first motor is fixed on the seat body, and the output shaft of the first motor is fixed on the rotating shaft of the front crushing roller.

[0006] Furthermore, a shearing component is also arranged in the crushing box, the shearing component includes a plurality of spring rods arranged on the front inner wall and the rear inner wall of the crushing box, the extending ends of the front spring rods are all fixed on a shearing plate, the extending ends of the rear spring rods are fixed on another shearing plate, the crushing teeth on the two shearing plates are engaged with each other, and the two shearing plates are located above the two crushing rollers.

[0007] Furthermore, each shear plate is welded with a stress rod, and the ends of the two stress rods away from the shear plates are respectively arranged on the teeth of two gears. When the two gears rotate, the stress rods are moved by the teeth to drive the two shear plates (302) away from each other in the horizontal direction.

[0008] Furthermore, a drawer is inserted into the crushing box, and the drawer is located below the two crushing rollers. The drawer is provided with screening holes in a linear array. The crushed molding waste fragments are screened through the screening holes and continue to fall downward, and larger molding waste fragments will remain on the drawer.

[0009] Furthermore, an auxiliary component is installed on the crushing box, which consists of a fan, an air intake pipe and an exhaust pipe. A fan is fixed on the right end face of the crushing box, and an air intake pipe and an exhaust pipe are connected to the fan. The air intake end of the air intake pipe is located above the drawer, and the exhaust end of the exhaust pipe is located above the two shear plates.

[0010] Furthermore, a funnel is welded in the crushing box, and the funnel is located below the drawer. A pulping assembly is installed in the crushing box, and the pulping assembly consists of a crushing barrel, a cover plate, a rotating shaft, an impeller and a second motor. A crushing barrel is fixed inside the crushing box, and a cover plate is fixed on the top of the crushing barrel. The funnel passes through the cover plate, and a rotating shaft rotates on the cover plate, and an impeller is fixed on the rotating shaft in a linear array. A second motor is fixed on the top surface of the cover plate, and the output shaft of the second motor is fixed on the rotating shaft.

[0011] Furthermore, a guide plate is fixed on the front inner wall and the rear inner wall of the crushing box, and the two guide plates are inclined from top to bottom toward the crushing teeth of the shear plate.

[0012] Furthermore, the contact ends between the two force-bearing rods and the gear are arc-shaped structures.

[0013] The present invention provides a pulp molding waste recycling device, which has the following beneficial effects: Efficient crushing, coordinated operation of crushing components: The crushing component consists of a crushing roller, gears, a base and a first motor. The first motor drives the front crushing roller to rotate, and through the mutually meshing first gears, the two crushing rollers rotate synchronously in opposite directions, effectively crushing the molding waste. This design ensures the stability and continuity of the crushing process and improves the crushing efficiency. Shearing component assistance: The shearing component located above the crushing roller includes a spring rod, a shear plate and a force rod. When the gear rotates, it moves the force rod, causing the two shear plates to move back and forth to pre-shear the molding waste. This not only facilitates subsequent crushing work, but also preliminarily processes the waste into a shape that is easier to crush, further improving the overall crushing efficiency.

[0014] Precise screening, drawer - type screening structure: The drawer inserted into the crushing box has screening holes linearly arrayed on it. The shredded molded waste fragments are screened through the screening holes, and the larger fragments remain on the drawer, achieving precise screening. This prevents oversized waste fragments from entering subsequent processes and affecting pulping, ensuring the smooth progress of subsequent processing.

[0015] Circular processing improves precision: The auxiliary component enables waste recycling: The auxiliary component consists of a blower, an intake pipe, and an exhaust pipe. After the blower is started, it can suck the large waste fragments remaining on the drawer and discharge them above the shear plate through the exhaust pipe for re - shearing and crushing. This circular processing mechanism effectively guarantees the processing precision, making the final waste treatment product more in line with requirements. The pulping function improves the processing flow, and the pulping component operates efficiently: The pulping component includes a crushing barrel, a cover plate, a rotating shaft, an impeller, and a second motor. After adding liquid into the crushing barrel, the second motor drives the rotating shaft and the impeller to rotate, pulping the screened waste fragments. This function improves the entire molded waste treatment process and further processes the waste into a usable slurry form.

[0016] Optimized structure reduces losses: The guide plate ensures the waste treatment effect: Two guide plates on the inner wall of the crushing box are mirror - image arranged and jointly form a waste guiding structure. It can ensure that the waste accurately enters between the two shear plates, guaranteeing the shearing effect of the waste and improving the waste treatment capacity of the equipment.

[0017] Optimization of the contact end of the force - bearing rod and the gear: The contact end of the force - bearing rod and the gear is polished into an arc - shaped structure. During the operation of the equipment, it greatly reduces the wear of the force - bearing rod and the gear, reduces the maintenance frequency and cost, and improves the service life of the equipment.

[0018] In summary, through the collaborative work of multiple components, this molded waste treatment equipment demonstrates advantages of high efficiency, precision, and low loss in various links such as crushing, screening, circular processing, and pulping, providing a reliable solution for the effective treatment of molded waste.

[0026] Embodiment 1: Please refer to Figures 1 to 8 : The present invention provides a device for recycling waste paper pulp molding, including: a crushing box 1; a crushing assembly 2 is arranged in the crushing box 1, and the crushing assembly 2 includes two crushing rollers 201 rotatably connected to the crushing box 1. The two crushing rollers 201 are engaged with each other. A first gear 202 is welded on the rotating shaft of each crushing roller 201, and the two first gears 202 are engaged; a seat body 203 is welded to the left end of the crushing box 1. The seat body 203 is an L-shaped structure, and a first motor 204 is fixed on the seat body 203. The output shaft of the first motor 204 is fixed on the rotating shaft of the front crushing roller 201. When crushing the molding waste, the first motor 204 is started. The first motor 204 drives the front crushing roller 201 to rotate. Through the engagement of the two first gears 202, the synchronous reverse rotation of the two crushing rollers 201 can be realized, and the crushing of the molding waste can be realized through the rotation of the two crushing rollers 201.

[0027] Among them, a shearing assembly 3 is further arranged in the crushing box 1. The shearing assembly 3 includes a plurality of spring rods 301 arranged on the front inner wall and the rear inner wall of the crushing box 1. The extended ends of the two front spring rods 301 are both fixed on a shearing plate 302, and the extended ends of the two rear spring rods 301 are fixed on another shearing plate 302. The crushing teeth on the two shearing plates 302 are engaged with each other. The two shearing plates 302 are located above the two crushing rollers 201. After the two shearing plates 302 located above the two crushing rollers 201 complete the shearing of the molding waste, it is convenient for the sheared molding waste to fall to the two crushing rollers 201, facilitating subsequent re-crushing.

[0028] Among them, a stress rod 303 is welded on each shear plate 302. The ends of the two stress rods 303 away from the shear plate 302 are respectively abutted on the tooth profiles of the two gears 202. When the two gears 202 rotate, the tooth profiles drive the stress rods 303 to drive the two shear plates 302 to move away from each other in the horizontal direction. During the meshing transmission of the two gears 202, the gears 202 can synchronously drive the two stress rods 303 and the two shear plates 302 to move away from each other. The spring rod 301 drives the two stress rods 303 and the two shear plates 302 to move closer to each other. The reciprocating movement of the two shear plates 302 back and forth can realize the shearing of the molded waste, and the subsequent crushing can be facilitated through shearing.

[0029] Among them, a drawer 4 is inserted into the crushing box 1. The drawer 4 is located below the two crushing rollers 201. Screening holes 401 are arranged in a linear array on the drawer 4. After the crushed molded waste fragments are screened through the screening holes 401, they continue to fall downward. The larger molded waste fragments will remain on the drawer 4, realizing the screening of the waste and avoiding the influence on subsequent pulping due to the too large waste fragments.

[0030] Among them, an auxiliary component 7 is installed on the crushing box 1. The auxiliary component 7 is composed of a blower 701, an air inlet pipe 702 and an exhaust pipe 703. A blower 701 is fixed on the right end face of the crushing box 1. A air inlet pipe 702 and an exhaust pipe 703 are connected to the blower 701. The air inlet end of the air inlet pipe 702 is located above the drawer 4, and the exhaust end of the exhaust pipe 703 is located above the two shear plates 302. During use, the blower 701 is started. At this time, the large waste remaining on the drawer 4 is sucked into the blower 701, and then discharged to the position above the two shear plates 302 through the exhaust pipe 703, and is sheared again by the two shear plates 302, and then crushed again by the two crushing rollers 201, ensuring the processing accuracy. If there are still large waste pieces after re-crushing, at this time, the large waste pieces can also be recycled again through the blower 701 until all the waste can fall through the screening holes 401.

[0031] Among them, a funnel 5 is welded inside the crushing box 1. The funnel 5 is located below the drawer 4. A pulp shredding assembly 6 is installed inside the crushing box 1. The pulp shredding assembly 6 is composed of a crushing barrel 601, a cover plate 602, a rotating shaft 603, an impeller 604, and a second motor 605. A crushing barrel 601 is fixed inside the crushing box 1. A cover plate 602 is fixed on the top of the crushing barrel 601. The funnel 5 passes through the cover plate 602. Through the funnel 5, the screened waste can be introduced into the crushing barrel 601, eliminating the need for separate manual transfer of the crushed waste and saving time. A rotating shaft 603 is rotatably mounted on the cover plate 602. The impeller 604 is linearly and arrayedly fixed on the rotating shaft 603. A second motor 605 is fixed on the top end surface of the cover plate 602. The output shaft of the second motor 605 is fixed on the rotating shaft 603. During use, liquid is added to the crushing barrel 601, the second motor 605 is driven to rotate, the second motor 605 drives the rotating shaft 603 and the impeller 604 to rotate, and the rotation of the impeller 604 can achieve the pulping of waste fragments.

[0032] Among them, a guide plate 101 is fixed on the front end surface and the rear end surface of the inner wall of the crushing box 1 by screws. Both guide plates 101 are rectangular plate-like structures. The two guide plates 101 are arranged in a mirror image. The two guide plates 101 together form a guiding structure for waste. During use, the guiding of the two guide plates 101 can ensure that the waste enters between the two shear plates 302, ensuring the shearing effect of the waste.

[0033] Embodiment 2, on the basis of Embodiment 1, as Figures 1 - 8 shown, the contact ends of the two force-bearing rods 303 and the gear 202 are polished. After polishing, the contact ends of the two force-bearing rods 303 and the gear 202 are arc-shaped structures. During use, the wear of the force-bearing rods 303 and the gear 202 can be reduced, reducing the maintenance cost.

[0034] Working principle of this embodiment: Put the molded waste on the top of the crushing box 1. Under the guidance of two guiding plates 101, the wood-plastic waste enters the two shear plates 302. Start the first motor 204, and the first motor 204 drives the front crushing roller 201 to rotate. Through the meshing of two first gears 202, the synchronous reverse rotation of the two crushing rollers 201 can be realized. Through the rotation of the two crushing rollers 201, the crushing of the molded waste can be realized. During the meshing transmission of the two gears 202, the gears 202 can synchronously drive the two force rods 303 and the two shear plates 302 to reciprocate back and forth. Through the reciprocating back and forth movement of the two shear plates 302, the shearing of the molded waste can be realized, and the subsequent crushing can be facilitated through shearing. The crushed debris falls onto the drawer 4. At this time, the small pieces of waste fall into the funnel 5 and are conveyed to the inside of the crushing barrel 601 through the funnel 5. The large pieces of waste remain in the drawer 4. Start the blower 701. At this time, the large pieces of waste remaining on the drawer 4 are sucked into the blower 701 and then discharged to the upper position of the two shear plates 302 through the exhaust pipe 703, and are sheared again by the two shear plates 302, and then crushed again by the two crushing rollers 201. The waste after being crushed again finally passes through the screening holes 401 and enters the funnel 5, and then is conveyed to the inside of the crushing barrel 601 through the funnel 5. When pulping, add liquid to the crushing barrel 601, drive the second motor 605 to rotate, and the second motor 605 drives the rotating shaft 603 and the impeller 604 to rotate. Through the rotation of the impeller 604, the pulping of the waste fragments can be realized.
