Description

Technical Field

[0001] This utility model relates to the field of waste paper pulping technology, specifically a waste paper pulping device. Background Technology

[0002] In the current field of waste paper recycling and processing, pulping is a core process, and the level of its equipment technology directly affects resource recovery efficiency and processing costs. Existing waste paper pulping equipment mostly adopts complex mechanical transmission and multi-stage crushing structures, including multiple components such as motors, reducers, pulping discs, and mixing mechanisms. The intricate internal structure of the equipment not only increases the cost of equipment manufacturing and maintenance but also raises the technical threshold for operators, resulting in greater difficulty in troubleshooting and repairing equipment malfunctions.

[0003] In terms of equipment size, traditional pulping equipment is usually designed to be large and occupy a large area to meet the needs of large-scale production. It requires a dedicated large factory space for installation and operation. For small factories with limited factory space and insufficient capital investment, it is difficult to bear the cost of equipment installation and use, which greatly limits the enthusiasm of small enterprises to participate in the waste paper recycling business.

[0004] Furthermore, the existing pulping equipment's discharge system design has flaws. The discharge port's location and structure are unreasonable, easily leading to pulp blockage and poor discharge during the pulping process, especially when processing waste paper containing many impurities, where the blockage problem is more severe. At the same time, the discharge operation is cumbersome, requiring frequent manual intervention, increasing labor costs and intensity, reducing production efficiency, and failing to meet the demands of continuous production. Therefore, improvements are necessary. Utility Model Content

[0005] The purpose of this invention is to provide a waste paper pulping device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste paper pulping device, including a support frame, a pulping mechanism installed on the top of the support frame, and a discharge mechanism installed on the front side of the pulping mechanism;

[0007] The pulping mechanism includes a mixing tank, which is fixedly connected to the top inner side of a support frame. A mixing shaft is rotatably connected to the middle of the mixing tank. A mixing blade is fixedly connected to the outer wall of the mixing shaft inside the mixing tank. A shredder is fixedly connected to the mixing shaft next to the mixing blade. A first gear is fixedly connected to the right end of the mixing blade. A second gear is rotatably connected to the top right side of the support frame corresponding to the first gear. A rotating shaft is rotatably connected to the rear top side of the support frame. A third gear is fixedly connected to the right end of the rotating shaft. A pulley assembly is fixedly connected to the left end of the rotating shaft. A motor is fixedly connected to the bottom left side of the support frame.

[0008] Preferably, the mixing plate has support blocks installed at both ends on the top of the support frame, and the mixing plate is rotatably connected to the top of the support frame through the support blocks.

[0009] Preferably, the outer wall of the mixing shaft is provided with mixing plates at equal intervals, and the outer wall of the mixing shaft is provided with paper shredders at equal intervals between the mixing plates.

[0010] Preferably, the outer ring of the first gear meshes with the outer ring of the second gear, and the outer ring of the second gear meshes with the outer ring of the third gear.

[0011] Preferably, the pulley assembly consists of two pulleys connected by a belt drive, with one pulley fixedly connected to the left end of the rotating shaft and the other pulley fixedly connected to the left side of the motor.

[0012] Preferably, the discharge mechanism includes a chute, which is fixedly connected to the front side of the mixing tank. A baffle is slidably connected inside the chute. A push block is fixedly connected to the left side of the baffle. A hydraulic telescopic cylinder is fixedly connected to the middle of the push block. A fixed seat is fixedly connected to the hydraulic telescopic cylinder near the middle. The rear side of the fixed seat is fixedly connected to the front side of the mixing tank.

[0013] Preferably, a discharge port is provided on the front side of the mixing tank corresponding to the inner side of the chute, the hydraulic telescopic cylinder includes an outer cylinder and an inner rod, the outer cylinder of the hydraulic telescopic cylinder is fixedly connected to the fixed base, and the right end of the inner rod of the pushing block is fixedly connected to the pushing block.

[0014] Compared with the prior art, this utility model provides a waste paper pulping device, which has the following beneficial effects:

[0015] 1. This waste paper pulping device uses a motor to drive a rotating shaft via a pulley system. A third gear on the right end of the rotating shaft meshes with a second gear, which in turn meshes with a first gear on the mixing shaft, forming a three-stage transmission structure. This gear transmission method eliminates the need for a complex reducer; the rotational speeds of the mixing shaft and the shredder are matched simply by the gear tooth ratio. The mixing blades, staggered on the mixing shaft, rotate synchronously with the shredder. The mixing blades tumble the pulp, while the shredder cuts and shreds the paper. A single power source drives multiple functional components, reducing redundant parts.

[0016] Compared to traditional multi-stage crushing structures, this device integrates pulping and mixing functions through a gear transmission chain, eliminating the need for a separate mixing motor and complex couplings. Meanwhile, the support frame adopts a modular design, with the pulping and discharging mechanisms vertically arranged, allowing direct installation on a small factory workbench. This reduces equipment investment and space costs for small factories, addressing the pain point of traditional equipment being "large and complex."

[0017] 2. This waste paper pulping device connects to the mixing tank via a hydraulic telescopic cylinder of the discharge mechanism and a fixed base. When discharge is required, the hydraulic system drives the inner rod to extend, pushing the block to move the baffle upwards along the chute, exposing the discharge port at the front of the mixing tank. The baffle features an inclined cross-section design, which, combined with the chute's guiding angle, uses hydraulic force to forcibly push the pulp, preventing fiber entanglement and blockage. The discharge process can be automatically started and stopped via the control system, eliminating the need for frequent manual operation.

[0018] The traditional method of manually opening and closing valves or manually removing material for discharge has been completely replaced. The inclined discharge port and the sealing design of the baffle prevent pulp leakage during pulping. At the same time, when processing paper containing impurities, the hydraulic thrust can effectively break up clumps of pulp. In addition, the automated discharge process can be seamlessly connected to subsequent screening processes, solving the problems of cumbersome and inefficient discharge in traditional equipment.

[0027] This utility model provides the following technical solution:

[0028] Example 1

[0029] Please see Figure 1-3 A waste paper pulping device includes a support frame 1, a pulping mechanism 2 installed on the top of the support frame 1, and a discharge mechanism 3 installed on the front side of the pulping mechanism 2.

[0030] The pulping mechanism 2 includes a mixing tank 21, which is fixedly connected to the top inner side of the support frame 1. A mixing shaft 281 is rotatably connected to the middle of the mixing tank 21. A mixing plate 28 is fixedly connected to the outer wall of the mixing shaft 281 inside the mixing tank 21. A shredder 29 is fixedly connected to the mixing shaft 281 next to the mixing plate 28. A first gear 22 is fixedly connected to the right end of the mixing plate 28. A second gear 23 is rotatably connected to the top right side of the support frame 1 corresponding to the first gear 22. A rotating shaft 25 is rotatably connected to the top rear side of the support frame 1. A third gear 24 is fixedly connected to the right end of the rotating shaft 25. A pulley group 26 is fixedly connected to the left end of the rotating shaft 25. A motor 27 is fixedly connected to the bottom left side of the support frame 1.

[0031] The motor 27 drives the rotating shaft 25 to rotate via the pulley assembly 26. The third gear 24 on the right end of the rotating shaft 25 meshes with the second gear 23, which in turn meshes with the first gear 22 on the mixing shaft 281, forming a three-stage transmission structure. This gear transmission method eliminates the need for a complex reducer; the rotational speeds of the mixing shaft 281 and the shredder 29 are matched simply by the gear tooth ratio. The mixing blades 28, which are staggered on the mixing shaft 281, rotate synchronously with the shredder 29. The mixing blades 28 push the pulp to tumble, while the shredder 29 cuts and shreds the paper. A single power source drives multiple functional components, reducing redundant parts.

[0032] Compared to traditional multi-stage crushing structures, this device integrates pulping and mixing functions through a gear transmission chain, eliminating the need for a separate mixing motor 27 and complex couplings. Meanwhile, the support frame 1 adopts a modular design, with the pulping mechanism 2 and discharge mechanism 3 arranged vertically, allowing for direct installation on a small factory workbench. This reduces equipment investment and space costs for small factories, addressing the pain point of traditional equipment being "large and complex."

[0033] The two ends of the mixing plate 28 are equipped with support blocks at the top of the support frame 1, and the mixing plate 28 is rotatably connected to the top of the support frame 1 through the support blocks.

[0034] Mixing plates 28 are evenly distributed on the outer wall of the mixing shaft 281, and paper shredders 29 are evenly distributed between the mixing plates 28 on the outer wall of the mixing shaft 281.

[0035] The outer ring of the first gear 22 meshes with the outer ring of the second gear 23, and the outer ring of the second gear 23 meshes with the outer ring of the third gear 24.

[0036] The pulley assembly 26 consists of two pulleys connected by a belt drive. One pulley is fixedly connected to the left end of the rotating shaft 25, and the other pulley is fixedly connected to the left side of the motor 27.

[0037] Example 2

[0038] Please see Figure 1-4 Furthermore, based on Embodiment 1, the discharge mechanism 3 includes a chute 32, which is fixedly connected to the front side of the mixing tank 21. A baffle 31 is slidably connected inside the chute 32. A push block 33 is fixedly connected to the left side of the baffle 31. A hydraulic telescopic cylinder 34 is fixedly connected to the middle of the push block 33. A fixed seat 35 is fixedly connected to the middle of the hydraulic telescopic cylinder 34. The rear side of the fixed seat 35 is fixedly connected to the front side of the mixing tank 21.

[0039] The hydraulic telescopic cylinder 34 of the discharge mechanism 3 is connected to the mixing tank 21 via a fixed base 35. When discharge is required, the hydraulic system drives the inner rod to extend, pushing the block 33 to move the baffle 31 upward along the slide 32, exposing the discharge port at the front of the mixing tank 21. The baffle 31 adopts an inclined cross-section design, which, in conjunction with the guiding angle of the slide 32, uses hydraulic driving force to forcibly push the slurry, preventing fiber entanglement and blockage. The discharge process can be set to start and stop automatically through the control system, eliminating the need for frequent manual operation.

[0040] The traditional method of manually opening and closing valves or manually removing material for discharge has been completely replaced. The inclined discharge port and the sealing design of the baffle 31 prevent pulp leakage during pulping. At the same time, when processing paper containing impurities, the hydraulic thrust can effectively break up clumps of pulp. In addition, the automated discharge process can be seamlessly connected to subsequent screening processes, solving the problems of cumbersome and inefficient discharge in traditional equipment.

[0041] A discharge port is provided on the front side of the mixing tank 21 corresponding to the inner side of the slide 32. The hydraulic telescopic cylinder 34 includes an outer cylinder and an inner rod. The outer cylinder of the hydraulic telescopic cylinder 34 is fixedly connected to the fixed seat 35. The right end of the inner rod of the push block 33 is fixedly connected to the push block 33.

[0042] In actual operation, when this device is in use, the motor 27 drives the rotating shaft 25 to rotate via the pulley group 26. The third gear 24 on the right end of the rotating shaft 25 meshes with the second gear 23, and the second gear 23 meshes with the first gear 22 on the mixing shaft 281, forming a three-stage transmission structure. This gear transmission method does not require a complex reducer; the speed matching between the mixing shaft 281 and the shredder 29 can be achieved through the gear tooth ratio. The mixing blades 28, which are staggered on the mixing shaft 281, rotate synchronously with the shredder 29. The mixing blades 28 push the pulp to tumble, while the shredder 29 cuts and shreds the paper. A single power source drives multiple functional components, reducing redundant parts.

[0043] Compared to traditional multi-stage crushing structures, this device integrates pulping and mixing functions through a gear transmission chain, eliminating the need for a separate mixing motor 27 and complex couplings. Meanwhile, the support frame 1 adopts a modular design, with the pulping mechanism 2 and discharge mechanism 3 arranged vertically, allowing for direct installation on a small factory workbench. This reduces equipment investment and space costs for small factories, addressing the pain point of traditional equipment being "large and complex."

[0044] The hydraulic telescopic cylinder 34 of the discharge mechanism 3 is connected to the mixing tank 21 via a fixed base 35. When discharge is required, the hydraulic system drives the inner rod to extend, pushing the block 33 to drive the baffle 31 to slide upward along the chute 32, exposing the discharge port on the front side of the mixing tank 21. The baffle 31 adopts an inclined cross-section design, which, in conjunction with the guiding angle of the chute 32, uses hydraulic driving force to forcibly push the slurry, avoiding fiber entanglement and blockage. The discharge process can be set to start and stop automatically through the control system, eliminating the need for frequent manual operation.

[0045] The traditional method of manually opening and closing valves or manually removing material for discharge has been completely replaced.
