Description

Technical Field

[0001] This utility model relates to the field of waste rubber treatment, and in particular to an auxiliary waste rubber mechanochemical regeneration extruder. Background Technology

[0002] In the course of continuous global industrial development, rubber products, with their unique properties, have been widely used in numerous fields such as automobile manufacturing, transportation, construction engineering, and electronics. However, rubber products inevitably experience aging and wear during use, resulting in a large amount of waste rubber.

[0003] Current waste rubber processing typically involves pouring waste rubber into an extruder, adding a softener for degradation, followed by crushing, heating, filtration, and re-extrusion. However, most extruders currently have fixed filter screens, requiring the disassembly of numerous parts for replacement. This process is complex and cumbersome, consuming significant time and manpower, impacting replacement efficiency, and potentially causing equipment damage or affecting production precision due to improper operation.

[0004] Therefore, it is necessary to design an auxiliary waste rubber mechanochemical regeneration extruder that can process and filter waste rubber before extrusion, while facilitating the switching and removal of filter screens, making it easy to install, remove, clean, and replace filter screens, facilitating impurity removal, improving cleaning efficiency, and being easy to use. Utility Model Content

[0006] Technical Solution: An auxiliary waste rubber mechanochemical regeneration extruder includes a base, a housing, a feed inlet, a discharge plate, a molding port, a second electric push rod, a processing component, a filtering component, and a pushing component. Multiple bases are connected to the lower side of the housing. The feed inlet is connected to the upper left side of the housing. The discharge plate is rotatably connected to the upper right side of the housing. The molding port is snapped onto the upper right side of the housing and contacts the discharge plate. The second electric push rod is rotatably connected to the upper rear of the right base. The second electric push rod and the processor are electrically connected via a control module. The telescopic end of the second electric push rod is rotatably connected to the discharge plate. The housing is equipped with a processing component for processing waste rubber. The right side of the housing is equipped with a filtering component for filtering waste rubber. The right base is equipped with a pushing component for removing and replacing the filtering component.

[0007] Furthermore, it is particularly preferred that the processing assembly includes a motor, a first gear, a first extrusion rod, a second extrusion rod, and a heating coil. The motor is connected to the left rear part of the housing, and the motor and the processor are electrically connected through a control module. The first extrusion rod is rotatably connected to both the front and rear parts of the housing. The first extrusion rod at the rear is connected to the output shaft of the motor. The left side of each first extrusion rod is connected to a first gear, and the two first gears mesh with each other. The middle part of each first extrusion rod is connected to a second extrusion rod, and the heating coil is connected to the middle of the housing.

[0008] Furthermore, it is particularly preferred that the filter assembly includes a rotating disk, a gear ring, a second gear, and a filter screen. The rotating disk is rotatably connected to the right side of the housing, and the gear ring is connected to the rotating disk. The second gear is rotatably connected to the front of the base on the right side. The second gear meshes with the gear ring.

[0012] The beneficial effects are as follows: 1.

[0013] 2. This utility model achieves the installation and fixation of the molding orifice by snapping a molding orifice of suitable specifications and shape onto the outer shell, and then by reversing the operation of the second electric push rod, causing the discharge plate to rotate in the opposite direction and return to contact the molding orifice.

Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0021] An auxiliary mechanochemical regeneration extruder for waste rubber, such as Figures 1-5As shown, the assembly includes a base 1, a housing 2, a feed inlet 3, a discharge plate 4, a molding port 41, a second electric push rod 16, a processing component, a filtering component, and a pushing component. Three bases 1 are connected to the lower side of the housing 2. The feed inlet 3 is connected to the upper left side of the housing 2. The discharge plate 4 is rotatably connected to the upper right side of the housing 2. The molding port 41 is snapped onto the upper right side of the housing 2, and the molding port 41 contacts the discharge plate 4. The second electric push rod 16 is rotatably connected to the upper rear of the right base 1. The second electric push rod 16 and the processor are electrically connected via a control module. The telescopic end of the second electric push rod 16 is rotatably connected to the discharge plate 4. The housing 2 is equipped with a processing component for processing waste rubber. The right side of the housing 2 is equipped with a filtering component for filtering waste rubber. The right base 1 is equipped with a pushing component for removing and replacing the filtering component.

[0022] like Figure 2 As shown, the processing assembly includes a motor 5, a first gear 6, a first extrusion rod 7, a second extrusion rod 8, and a heating coil 9. The motor 5 is connected to the left rear part of the housing 2. The motor 5 and the processor are electrically connected through a control module. The first extrusion rod 7 is rotatably connected to both the front and rear parts of the housing 2. The first extrusion rod 7 at the rear is connected to the output shaft of the motor 5. The first gear 6 is connected to the left side of the first extrusion rod 7. The two first gears 6 mesh with each other. The second extrusion rod 8 is connected to the middle of the first extrusion rod 7. The heating coil 9 is connected to the middle of the housing 2.

[0023] like Figure 3 , Figure 4 and Figure 5 As shown, the filter assembly includes a rotating disk 10, a gear ring 101, a second gear 12, and a filter screen 15. The rotating disk 10 is rotatably connected to the right side of the outer casing 2, and the gear ring 101 is connected to the rotating disk 10. The second gear 12 is rotatably connected to the front of the base 1 on the right side. The second gear 12 meshes with the gear ring 101. The first gear 6 and the second gear 12 have different shapes. The filter screen 15 is engaged on both the upper and lower parts of the rotating disk 10. It also includes a rocker arm 11. The rocker arm 11 is connected to the right side of the second gear 12, making it easy to hold and rotate the second gear 12.

[0024] like Figure 3 and Figure 5 As shown, the feeding assembly includes a first electric push rod 13 and a push block 14. The first electric push rod 13 is connected to the lower part of the base 1 on the right side. The first electric push rod 13 and the processor are electrically connected through a control module. The telescopic end of the first electric push rod 13 passes through the base 1 on the right side and is connected to the push block 14.

[0025] This device can be used when assisting in the regeneration and extrusion of waste rubber. The base 1 is brought into contact with the ground, and the waste rubber is poured into the feed inlet 3, falling into the outer shell 2. A softening agent is then poured into the feed inlet 3 and flows into the outer shell 2 to contact the waste rubber, disrupting its structure and causing desulfurization or degradation. The processor then starts the motor 5 via the control module, which drives the corresponding first extrusion rod 7 to rotate, causing the first gear 6 to rotate. The two first gears 6 mesh, causing the other first extrusion rod 7 to rotate, extruding, shearing, and conveying the waste rubber. This causes physical and chemical changes in the waste rubber under mechanical force. The waste rubber is then heated by the heating coil 9, further softening it and promoting structural disruption and regeneration. After regeneration, the waste rubber is crushed by the rotation of the second extrusion rod 8, forming smaller particles. These particles are then conveyed by the first extrusion rod 7, passing through the filter screen 15 for filtration, and flowing into the space between the right side of the outer shell 2 and the discharge plate 4. They are then extruded from the molding orifice 41, thus completing the regeneration process. During the mechanochemical regeneration extrusion of waste rubber, impurities remain on the left side of the filter screen 15 during filtration. After use, the motor 5 and heating coil 9 are turned off. Then, the second gear 12 is rotated by the rocker arm 11. The second gear 12 meshes with the gear ring 101, causing the rotating disk 10 to rotate, thereby rotating the lower filter screen 15 to the upper part for use. The first gear 6 and the second gear 12 have different shapes. Then, the first electric push rod 13 is activated, which drives the push block 14 to move and push. The lower filter screen 15 is moved and removed to push out impurities. Then, the first electric push rod 13 operates in the opposite direction, causing the push block 14 to move and reset. Next, the filter screen 15 is cleaned or replaced. Then, the new or cleaned filter screen 15 is snapped into the rotating disk 10 for installation. Subsequently, the device is used to process waste rubber. This allows for the processing and filtration of waste rubber, while simultaneously facilitating the switching and removal of the filter screen 15. It is convenient for the installation, removal, cleaning, and replacement of the filter screen 15, facilitates the removal of impurities, improves cleaning efficiency, and is easy to use.

[0026] Before processing waste rubber, according to extrusion requirements, the second electric push rod 16 is activated, which pushes the discharge plate 4 to rotate and open. This causes the second electric push rod 16 to rotate, and then the molding nozzle 41 of appropriate specifications and shape is engaged with the outer shell 2. Then, the second electric push rod 16 operates in reverse, causing the discharge plate 4 to rotate in the opposite direction and return to contact the molding nozzle 41. This causes the second electric push rod 16 to rotate and return to its original position, thus fixing the molding nozzle 41 in place. This allows for the installation of molding nozzles 41 of different specifications and shapes for waste rubber extrusion, facilitating the production of products of various specifications and shapes, improving resource utilization, and providing flexible use. The waste rubber is then processed.
