Abstract
Description
Technical Field
[0001] The present application relates to a zipper recycling device, and in particular to a shredder. Background Art
[0002] The origin of resin zippers can be traced back to the mid-20th century. As people's demand for new zipper materials increased, resin zippers gradually became popular due to their unique properties. Resin zippers are usually made of environmentally friendly materials such as polyester or nylon. No harmful substances such as heavy metals are used in the production process, which is more environmentally friendly. In the production process of resin zippers, a common link is to process the waste rods for secondary use. After the waste rods are cut and crushed, the resulting fragments have a smaller particle size and are more suitable for subsequent reuse. To achieve this purpose, a crusher is usually used.
[0003] In the related art, a crusher generally includes a frame, a crushing bin arranged on the frame, a crushing assembly located in the crushing bin, and a feeding bin connected to the feeding port on the crushing bin. The crushing assembly includes a crushing roller and a driving motor for driving the crushing roller to operate. A material box is arranged in the frame and is located directly below the discharge port of the crushing bin. After the crushing is completed, the crushed materials will automatically fall into the material box and be collected.
[0004] However, in actual operation, the handling of the bin becomes a potential problem. Since the bin is usually made of stainless steel, it is heavy after loading the crushed material, which causes workers to spend a lot of time and energy to manually pull and reset the bin. In addition, workers are prone to fatigue after long-term operation. If they accidentally bump into the corners of the bin, it may also cause safety hazards. Utility Model Content
[0005] The purpose of the present application is to provide a pulverizer to solve the problem in the above-mentioned related art that the material box is time-consuming and labor-intensive and has potential safety hazards during the pulling and resetting process.
[0006] The present application provides a pulverizer adopting the following technical solution:
[0007] A crusher comprises a frame, a crushing bin arranged on the frame, a feeding bin connected with the inlet of the crushing bin, and a collection box located below the outlet of the crushing bin, wherein a crushing assembly is arranged in the crushing bin, and an installation cavity which is connected with the outlet of the crushing bin and for the collection box to be placed is arranged inside the frame; the frame is fixedly provided with a base plate with one end extending to the outside on the bottom side of the installation cavity, the inside of the installation cavity is provided with a push plate which is slidably arranged on the base plate, and a power source for driving the push plate to slide back and forth toward the outer end of the base plate, and the collection box is arranged on the upper side of the push plate.
[0008] By adopting the above technical scheme, the waste to be crushed is injected into the interior of the crushing bin through the feed bin, and then crushed by the crushing assembly, and finally the crushed waste falls into the interior of the aggregate box; when the crushed materials inside the aggregate box are collected, the power source is started, and then the aggregate box on the push plate is moved to the upper side of the outer end of the base plate, so as to facilitate the subsequent collection and recovery of the crushed materials in the aggregate box, thereby improving the work efficiency of dragging the aggregate box, and also reducing the corresponding safety hazards.
[0009] Optionally, a hinged seat is fixedly provided on the edge of the upper side of the push plate, and a rotating shaft rotatably connected to the hinged seat is fixedly provided on the bottom edge of the collection box; a driving component for driving the rotating shaft to rotate around its own axis is provided on the upper side of the outer end of the base plate.
[0010] By adopting the above technical scheme, due to the coordinated arrangement of the articulated seat, the rotating shaft and the driving assembly, when the aggregate box moves to the upper side surface of the outer end of the base plate, the driving assembly can drive the aggregate box to rotate around the axis of the rotating shaft, so that the aggregate box is tilted, and the crushed material in the aggregate box is discharged, thereby further improving the recovery efficiency of the crushed material in the aggregate box.
[0011] Optionally, the driving assembly includes a driving rack slidably arranged on the upper side surface of the outer end portion of the base plate and a second electric cylinder fixedly arranged on the upper side surface of the outer end portion of the base plate, the second electric cylinder being used to drive the driving rack to slide back and forth along its own length direction; a driving gear is fixedly arranged on the outer periphery of the end portion of the rotating shaft close to the driving rack, and the rotating shaft is perpendicular to the length direction of the driving rack; the driving gear can engage with the driving rack as the aggregate box slides.
[0012] By adopting the above technical solution, due to the coordinated arrangement of the driving rack, the driving gear and the second electric cylinder, when the push plate and the material collection box slide to the outer end of the base plate, the driving gear can engage with the driving rack. In this state, the second electric cylinder is started to drive the driving rack to slide, thereby causing the driving gear and the rotating shaft to rotate around their own axis, thereby realizing the rotation control of the material collection box.
[0013] Optionally, a limit plate is fixedly provided on the upper side of the base plate, the limit plate is located on the side of the driving rack away from the aggregate box, and the limit plate is used to limit the sliding stroke of the aggregate box.
[0014] By adopting the above technical solution, due to the installation of the limit plate, the sliding stroke of the push plate is limited, thereby reducing the possibility that the drive gear and the drive rack cannot mesh due to excessive sliding of the push plate.
[0015] Optionally, a shock-absorbing pad is fixedly provided on the side of the limiting plate facing the aggregate box.
[0016] By adopting the above technical solution, when the driving gear is meshed with the driving rack, due to the setting of the shock-absorbing pad on the limit plate, the shock-absorbing pad on the limit plate abuts against the outer end of the rotating shaft, thereby limiting the sliding stroke of the aggregate box.
[0017] Optionally, an elastic pad is fixedly provided on the bottom side of the aggregate box.
[0018] By adopting the above technical solution, since the bottom side of the material collecting box is provided with an elastic pad, the possibility of the material collecting box being damaged by colliding with the side surface of the push plate when rotating and resetting is reduced.
[0019] Optionally, a limiting convex strip is fixedly provided on the side of the elastic pad away from the collecting box, and a limiting groove is formed on the push plate for the limiting convex strip to be rotatably inserted into.
[0020] By adopting the above technical solution, when the elastic pad on the bottom side of the aggregate box abuts against the upper side of the push plate, due to the matching setting of the limiting protrusion and the limiting groove, the limiting protrusion is inserted into the corresponding limiting groove, thereby improving the installation stability of the aggregate box in this state.
[0021] Optionally, a guide rail with a dovetail-shaped cross-section is fixedly provided on the bottom side of the push plate, and a guide groove for the guide rail to be inserted and slide is opened on the base plate.
[0022] By adopting the above technical solution, due to the matching arrangement of the guide rail and the guide slot, when the push plate slides, the guide rail on the push plate slides back and forth along the length direction of the guide slot, thereby improving the stability during the sliding process.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. Due to the coordinated setting of the push plate and the power source, when the crushed materials inside the aggregate box are collected, the power source is started, and then the aggregate box on the push plate is moved to the upper side of the outer end of the base plate, so as to facilitate the subsequent collection and recovery of the crushed materials in the aggregate box, thereby improving the work efficiency of dragging the aggregate box and reducing the corresponding safety hazards.
[0025] 2. Due to the coordinated arrangement of the articulated seat, the rotating shaft and the driving assembly, when the aggregate box moves to the upper side surface of the outer end portion of the base plate, the driving assembly can drive the aggregate box to rotate around the axis of the rotating shaft, so that the aggregate box is tilted, and the crushed material in the aggregate box is discharged, thereby further improving the recovery efficiency of the crushed material in the aggregate box.

DETAILED DESCRIPTION
[0034] The present application is further described in detail below in conjunction with all the accompanying drawings.
[0035] Example:
[0036] Reference Figure 1 and Figure 2 A pulverizer includes a frame 1, a crushing bin 2 arranged on the frame 1, a feed bin 3 connected to the inlet of the crushing bin 2, and a collection box 4 located below the outlet of the crushing bin 2. The frame 1 is provided with an installation cavity 11 connected to the outlet of the crushing bin 2 and for the collection box 4 to be placed therein;
[0037] A crushing assembly 5 (not shown in the figure) is provided in the crushing bin 2, and the crushing assembly 5 includes a crushing roller 51 rotatably provided in the crushing bin 2, and a driving motor 52 for driving the crushing roller 51 to operate, wherein the driving motor 52 is located outside the crushing bin 2 and fixedly mounted on the upper side of the frame 1. The waste to be crushed is injected into the crushing bin 2 through the feed bin 3, and then crushed by the crushing assembly 5, and finally the crushed waste falls into the collecting box 4.
[0038] Reference Figure 2 and Figure 3 The frame 1 is fixedly provided with a base plate 12 with one end extending to the outside at the bottom side of the installation cavity 11, wherein the interior of the installation cavity 11 is provided with a push plate 6 slidably arranged on the base plate 12 and a power source 7 for driving the push plate 6 to move back and forth, and the collection box 4 is arranged on the inner wall of the installation cavity;
[0039] The power source 7 is a first electric cylinder 71 that is located inside the installation cavity 11 and fixed on the side of the base plate 12. This is a conventional driving structure and will not be described in detail here. The telescopic rod of the first electric cylinder 71 is fixedly connected to the side of the push plate 6 facing the inside of the installation cavity 11. When the first electric cylinder 71 is started, it drives the push plate 6 and the collection box 4 on the push plate 6 to reciprocate toward the direction close to the outer end of the base plate 12.
[0040] Reference Figure 4 Two guide rails 61 with dovetail-shaped cross-sections are fixedly provided on the bottom side of the push plate 6. At the same time, a guide groove 121 for the guide rails 61 to be inserted and slide is opened on the base plate 12. When the push plate 6 slides, it reciprocates along the length direction of the guide groove 121 to improve the stability during the sliding process.
[0041] Reference Figure 4 and Figure 5 A hinge seat 62 is fixedly provided on the edge of the upper side of the push plate 6, and a rotating shaft 41 rotatably connected to the hinge seat 62 is fixedly provided on the bottom edge of the collection box 4; wherein a driving component 8 for driving the rotating shaft 41 to rotate around its own axis is provided on the upper side of the outer end of the base plate 12; when the push plate 6 drives the collection box 4 to move to the upper side of the outer end of the base plate 12, the driving component 8 can drive the collection box 4 to rotate around the axis of the rotating shaft 41, thereby discharging the crushed material in the collection box 4.
[0042] Reference Figure 5 and Figure 6 The driving assembly 8 includes a driving rack 81 slidably arranged on the upper side of the outer end of the base plate 12 and a second electric cylinder 82 fixedly arranged on the upper side of the outer end of the base plate 12, wherein the second electric cylinder 82 is used to drive the driving rack 81 to slide back and forth along its own length direction, and the rotating shaft 41 is perpendicular to the length direction of the driving rack 81;
[0043] A driving gear 42 is fixedly provided on the outer periphery of the end of the rotating shaft 41 close to the driving rack 81. When the push plate 6 and the collecting box 4 slide to the outer end of the base plate 12, the driving gear 42 can engage with the driving rack 81. In this state, there is a gap between the second electric cylinder 82 and the collecting box 4. Starting the second electric cylinder 82 drives the driving rack 81 to slide, thereby causing the driving gear 42 and the rotating shaft 41 to rotate around their own axes.
[0044] Reference Figure 5 A limit plate 122 is fixedly provided on the upper side of the base plate 12, wherein the limit plate 122 is located on the side of the driving rack 81 away from the aggregate box 4, and the limit plate 122 is used to limit the sliding stroke of the aggregate box 4; a shock-absorbing pad 123 made of rubber is fixedly provided on the side of the limit plate 122 facing the aggregate box 4, so as to reduce the possibility that the outer end of the rotating shaft 41 will collide and damage one side of the limit plate 122.
[0045] Reference Figure 6 The bottom side of the material collecting box 4 is fixed with a rubber elastic pad 43 to reduce the possibility of damage caused by collision with the upper side of the push plate 6 when the material collecting box 4 is rotated and reset. A limiting convex strip 431 is integrally formed on the side of the elastic pad 43 away from the material collecting box 4, wherein the cross-sectional shape of the limiting convex strip 431 is semicircular, and a limiting groove 63 is provided on the push plate 6 for the limiting convex strip 431 to be rotatably inserted; when the elastic pad 43 on the bottom side of the material collecting box 4 abuts against the upper side of the push plate 6, the limiting convex strip 431 is inserted into the corresponding limiting groove 63, thereby improving the installation stability of the material collecting box 4 in this state.
[0046] The implementation principle of the embodiment of the present application is:
[0047] Under normal circumstances, the collection box 4 is inside the installation cavity 11 and is located below the outlet of the crushing bin 2. When the crushed material inside the collection box 4 is collected, the power source 7 is operated to move the collection box 4 on the push plate 6 to the upper side of the outer end of the base plate 12; then the driving gear 42 on the rotating shaft 41 is engaged with the driving rack 81 on the base plate 12, and then the second electric cylinder 82 is started to drive the collection box 4 to rotate around the axis of the rotating shaft 41, thereby discharging the crushed material in the collection box 4.
