Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber processing technology, specifically to a rubber processing pulverizer. Background Technology
[0002] Currently, rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformations under small external forces. After the external force is removed, it can return to its original shape. Rubber is a completely amorphous polymer with a low glass transition temperature and often a large molecular weight. Rubber products are widely used in various aspects of industry and life. Rubber is one of the most important production materials in industry.
[0003] When rubber reaches its designated service life, it needs to be recycled for reprocessing. The first step in recycling rubber is to crush larger rubber objects into smaller pieces. This process requires the use of a crusher. The crusher crushes the rubber objects through a crushing chamber. A crushing shaft is installed inside the crushing chamber. When the crushing shaft rotates, it drives the blades to rotate, thus crushing the rubber objects. However, at present, the crushing shaft and blades cannot be extended or retracted during use (the crushing shaft is generally rotatably connected to the crushing chamber). This results in a single crushing area for the blades, and the crushing space cannot be expanded by moving the crushing shaft. Therefore, the crushing effect is not good enough, not uniform enough, inefficient, and takes a long time to crush. Therefore, improvements are needed. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] In view of the shortcomings of the existing technology, this utility model provides a pulverizer for rubber processing, which solves the problem of the general pulverization effect at present.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0008] A rubber pulverizer includes a worktable and a pulverizing box fixedly connected to the worktable. A first pulverizing shaft and a second pulverizing shaft are slidably connected to the pulverizing box. Pulverizing blades are fixedly connected to both the first and second pulverizing shafts. A reciprocating drive mechanism is installed on the worktable. A carrier plate is provided on the top of the reciprocating drive mechanism. A drive component is installed on the carrier plate. The output shaft of the drive component is fixedly connected to the second pulverizing shaft. The reciprocating drive mechanism can drive the carrier plate to move back and forth, thereby realizing the reciprocating drive processing of the drive component, the first pulverizing shaft, and the second pulverizing shaft, and achieving rapid pulverization of rubber materials.
[0009] Furthermore, an L-shaped plate is fixedly connected to the carrier plate, and a connecting plate is fixedly connected to the L-shaped plate. Both the first crushing shaft and the second crushing shaft are rotatably connected to the connecting plate. When the carrier plate moves, the first crushing shaft and the second crushing shaft can be stably extended and retracted through the connecting plate.
[0010] Furthermore, gears are fixedly connected to both the first and second crushing shafts, and the two gears are meshed together.
[0011] Furthermore, the reciprocating drive mechanism includes a protective frame fixedly connected to the workbench, and a reciprocating lead screw rotatably connected to the protective frame. The reciprocating lead screw is fitted with a telescopic block, and a support plate is fixedly attached to the top of the telescopic block. The support plate is connected and fixedly attached to the carrier plate.
[0012] Furthermore, a first motor for driving the reciprocating lead screw to rotate is installed on one side of the protective frame, and a guide rod is fixedly connected to the protective frame. The telescopic block is provided with a guide hole that matches the guide rod at the corresponding position of the guide rod.
[0013] (III) Beneficial Effects
[0014] Compared with the prior art, the present invention provides a pulverizer for rubber processing, which has the following beneficial effects:
[0015] This invention utilizes two symmetrically distributed crushing shafts, known as Crushing Shaft 1 and Crushing Shaft 2, which are slidably connected on a crushing chamber. Crushing Shaft 1 and Crushing Shaft 2 rotate in opposite directions, crushing rubber objects through crushing blades. Both crushing shafts are slidably connected to the crushing chamber, and a reciprocating drive mechanism is installed on the worktable. When the reciprocating drive mechanism is working, it drives the carrier plate to move back and forth, thereby causing the drive components, connecting plate, Crushing Shaft 1, and Crushing Shaft 2 to extend and retract stably. During this extension and retraction, the crushing blades move, expanding their crushing area. This movement of the crushing blades ensures uniform crushing of the rubber objects within the crushing chamber, resulting in a uniform and rapid crushing effect. Compared to traditional devices, this invention reduces time and improves the crushing effect of rubber. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example
[0024] like Figure 1 and Figure 2 As shown in the figure, an embodiment of the present invention provides a rubber processing pulverizer, including a workbench 1 and a pulverizing box 2 fixedly connected to the workbench 1. A first pulverizing shaft 3 and a second pulverizing shaft 9 are slidably connected to the pulverizing box 2. Pulverizing blades 4 are fixedly connected to both the first pulverizing shaft 3 and the second pulverizing shaft 9. Meanwhile, a reciprocating drive mechanism 5 is installed on the workbench 1. A carrier plate 6 is provided on the top of the reciprocating drive mechanism 5. A drive component 11 is installed on the carrier plate 6. The output shaft of the drive component 11 is connected and fixedly connected to the second pulverizing shaft 9. The reciprocating drive mechanism 5 can drive the carrier plate 6 to move back and forth, thereby realizing the reciprocating drive processing of the drive component 11, the first pulverizing shaft 3 and the second pulverizing shaft 9, and realizing the rapid pulverization of rubber objects.
[0025] It should be noted that the workbench 1 is the supporting part of the crusher. Crushing shaft 3 and crushing shaft 9 are slidably connected inside the crushing box 2. Crushing shaft 3 and crushing shaft 9 can extend and retract synchronously. During the extension and retraction, the crushing blade 4 moves, thereby achieving uniform crushing of rubber objects and increasing the crushing effect of rubber. By installing a reciprocating drive mechanism 5 on the workbench 1, the reciprocating drive mechanism 5 can drive the carrier plate 6 to move back and forth when it is working. This causes the drive component 11, crushing shaft 3 and crushing shaft 9 to move back and forth, thereby achieving rapid crushing of rubber. The drive component 11 realizes the rotation drive of crushing shaft 3 and crushing shaft 9.
[0026] like Figure 1 and Figure 2 As shown, in some embodiments, an L-shaped plate 7 is fixedly connected to the carrier plate 6, and a connecting plate 8 is fixedly connected to the L-shaped plate 7. The first crushing shaft 3 and the second crushing shaft 9 are both rotatably connected to the connecting plate 8. When the carrier plate 6 moves, the first crushing shaft 3 and the second crushing shaft 9 can be stably extended and retracted through the connecting plate 8.
[0027] It should be noted that both the first crushing shaft 3 and the second crushing shaft 9 are rotatably connected to the connecting plate 8. The connecting plate 8 is designed to limit the rotation of the first crushing shaft 3 and the second crushing shaft 9 and provide support. When the connecting plate 8 moves, the first crushing shaft 3 and the second crushing shaft 9 move accordingly, achieving stable extension and retraction of the first crushing shaft 3 and the second crushing shaft 9.
[0028] like Figure 1 and Figure 2 As shown, in some embodiments, gears 10 are fixedly connected to both the first crushing shaft 3 and the second crushing shaft 9, and the two gears 10 are meshed together.
[0029] It should be noted that the gear 10 enables the synchronous rotation of the first crushing shaft 3 and the second crushing shaft 9. The drive component 11 can drive the second crushing shaft 9 to rotate. During rotation, the first crushing shaft 3 and the second crushing shaft 9 can rotate in opposite directions through the relationship of the gear 10, thereby achieving rapid crushing of rubber.
[0030] like Figure 2 and Figure 3 As shown, in some embodiments, the reciprocating drive mechanism 5 includes a protective frame 501 fixedly connected to the worktable 1, and a reciprocating screw 502 rotatably connected to the protective frame 501. The reciprocating screw 502 is equipped with a telescopic block 505, and a support plate 503 is fixedly fixed to the top of the telescopic block 505. The support plate 503 is connected and fixed to the carrier plate 6.
[0031] It should be noted that when the reciprocating screw 502 rotates, it can drive the telescopic block 505 to move back and forth, which in turn causes the support plate 503 to move back and forth. The support plate 503 is connected and fixed to the carrier plate 6, thereby realizing the movement control of the carrier plate 6.
[0032] like Figure 3 As shown, in some embodiments, a first motor 506 for driving the reciprocating screw 502 to rotate is installed on one side of the protective frame 501, and a guide rod 504 is fixedly connected to the protective frame 501. The telescopic block 505 is provided with a guide hole that matches the guide rod 504 at the corresponding position of the guide rod 504.
[0033] It should be noted that the first motor 506 enables the rotation control of the reciprocating screw 502, thereby enabling the telescopic block 505 to move telescopically, and the guide rod 504 enables the telescopic block 505 to be limited and guided.
[0034] like Figure 4 and Figure 5 As shown, unlike the above-mentioned scheme, this utility model can also realize the reciprocating drive of the carrier plate 6 through the reciprocating module 12, thereby realizing the reciprocating extension and retraction of the drive component 11, the first crushing shaft 3, and the second crushing shaft 9. This extension and retraction method does not require the use of the reciprocating drive mechanism 5. The reciprocating module 12 includes a track plate 1201 and a second motor 1206, etc. The track plate 1201 is fixedly connected to the worktable 1, and a sliding block 1202 is slidably connected to the track plate 1201. The sliding block 1202 is fixedly connected to the carrier plate 6. When the sliding block 1202 slides on the track plate 1201, it can drive the carrier plate 6 to move. The second motor 1206 is installed on the worktable 1. On the lower surface, a drive shaft 1205 is coaxially arranged on one side of the second motor 1206. The upper end of the drive shaft 1205 extends to the top of the worktable 1 and a turntable 1204 is fixed thereon. A connecting rod 1203 is rotatably connected between one side of the turntable 1204 and the sliding block 1202. When in use, the second motor 1206 is driven to work. The second motor 1206 drives the drive shaft 1205 and the turntable 1204 to rotate. When the turntable 1204 rotates, the connecting rod 1203 can swing, thereby realizing the reciprocating drive of the sliding block 1202 on the track plate 1201, realizing the reciprocating extension and retraction of the carrier plate 6, thereby realizing the extension and retraction control of the drive component 11, the first crushing shaft 3 and the second crushing shaft 9.
[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
