A recycled rubber extrusion molding apparatus

Abstract

This utility model discloses a recycled rubber extrusion molding device, relating to the field of recycled rubber technology. It includes a fixed base with an extrusion tube fixedly connected to one side. A spiral auger is installed inside the fixed base, with one end passing through one side of the fixed base and rotatably connected to it. One end of the spiral auger has a motor disassembly structure, and the other end extends into the extrusion tube. By operating a ring handle, a rotating ring rotates on the extrusion tube. Simultaneously, the ring handle rotates, driving multiple rollers to rotate via multiple connecting columns. These rollers enter multiple inclined grooves and compress the extrusion block.

A square groove is opened at one end of the auger, and the square block is disposed inside the square groove. A limiting frame is fixedly connected to the outer side of the motor body, and multiple fixing grooves are opened on the outer side of the limiting frame. The limiting frame is disposed inside the limiting seat. The dust cover can achieve the effect of dust prevention.

[0009] Preferably, the motor disassembly structure further includes a rotating disk, which is rotatably connected to the outside of the limiting seat. A worm gear is fixedly connected to the outside of the rotating disk, and a worm is meshed with the outside of the worm gear. Both ends of the worm pass through the inside of the dust cover and are rotatably connected to the dust cover. A throttle handle is installed at one end of the worm.

[0010] Preferably, the outer side of the rotating disk is provided with multiple arc-shaped grooves, and a sliding column is slidably arranged inside the arc-shaped grooves. A fixed rod is installed at one end of the sliding column. The outer side of the limiting seat is provided with multiple sliding grooves, and the multiple sliding grooves are all in communication with the interior of the limiting seat. The multiple fixed rods are respectively arranged inside the multiple sliding grooves.

[0011] Preferably, an installation groove is provided at one end of the extrusion tube, and a high-temperature resistant sealing gasket is installed on one side of the mold.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application utilizes an annular handle, which drives a rotating ring to rotate on the extrusion tube. Simultaneously, the annular handle rotates, causing multiple rollers to rotate via multiple connecting columns. These rollers enter multiple inclined slots and compress the extrusion block.

[0016] 2. This application utilizes a worm gear and a worm wheel meshing together. The worm wheel drives a rotating disk to rotate on a limiting seat. During the rotation of the rotating disk, multiple arc-shaped grooves on its outer side guide multiple sliding columns inside to slide. The sliding of the sliding columns in the arc-shaped grooves causes the fixing rod at one end to unfold, and the limiting seat moves out of the fixing groove. Therefore, the fixing effect on the motor body is released, and the motor body can be quickly removed from the device for easy maintenance or replacement by operators. Attached Figure Description

[0023] 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.

[0024] Example: Figure 1 - Figure 5As shown, this utility model provides a technical solution for a recycled rubber extrusion molding device, including a fixed base 1, a hopper 100 installed on the top of the fixed base 1, the hopper 100 being fixedly connected to the fixed base 1, an extrusion tube 2 being fixedly connected to one side of the fixed base 1, a spiral auger 3 being provided inside the fixed base 1, one end of the spiral auger 3 passing through one side of the inside of the fixed base 1 and being rotatably connected to the fixed base 1, a motor disassembly structure being provided at one end of the spiral auger 3, and the other end of the spiral auger 3 extending into the inside of the extrusion tube 2, a mold 15 being provided at one end of the extrusion tube 2, and multiple T-slots 201 being opened at one end of the extrusion tube 2, multiple T-blocks 150 being fixedly connected to one side of the mold 15, the T-blocks 150 being disposed inside the T-slots 201 and slidably connected to the extrusion tube 2, and an extrusion roller 151 being installed on the top of one end of the T-block 150. One end of the extrusion tube 2 has an installation groove 200. A high-temperature resistant sealing gasket 152 is installed on one side of the mold 15. The high-temperature resistant sealing gasket 152 is set inside the installation groove 200. Multiple extrusion blocks 16 are provided on the outside of the extrusion tube 2. An elastic structure is provided between the extrusion blocks 16 and the extrusion tube 2. The elastic structure includes two T-shaped pillars 17. Both T-shaped pillars 17 are set on the outside of the extrusion blocks 16. Both T-shaped pillars 17 penetrate the extrusion blocks 16 and are slidably connected to the extrusion blocks 16. Both T-shaped pillars 17 are fixedly connected to the extrusion tube 2. A spring 18 is sleeved on the outside of the T-shaped pillars 17. The two ends of the spring 18 are fixedly connected to the extrusion blocks 16 and the T-shaped pillars 17 respectively. A slot 19 is opened at the bottom of the extrusion block 16. The extrusion wheel 151 is set inside the slot 19. A rotating structure is provided between the multiple extrusion blocks 16.

[0025] The rotating structure includes multiple inclined grooves 20 and a rotating ring 21. The multiple inclined grooves 20 are respectively opened at one end of multiple extrusion blocks 16. The rotating ring 21 is rotatably connected to the outside of the extrusion tube 2. An annular handle 22 is fixedly connected to the outside of the rotating ring 21. A connecting post 23 is fixedly connected to one side of the annular handle 22. A roller 24 is rotatably connected to one end of the connecting post 23.

[0026] Specifically, when mold 15 needs to be installed, the operator aligns multiple T-shaped blocks 150 on mold 15 with multiple T-shaped slots 201 on extrusion tube 2, and then pushes mold 15 towards extrusion tube 2. During this process, multiple extrusion rollers 151 on mold 15 will contact and extrusion blocks 16 on the outside of extrusion tube 2, and extrusion blocks 16 will be squeezed. After being squeezed, extrusion blocks 16 will slide on T-shaped posts 17, thus exhibiting an unfolded state. At the same time, springs 18 connected to extrusion blocks 16 will be elastically compressed due to the sliding of extrusion blocks 16. When the extrusion rollers 151 are pushed to a certain position, springs 18 will use their elastic return characteristics to push extrusion blocks 16 back to their original position. Finally, the extrusion rollers 151 will be accurately placed in the slots 19 at the bottom of extrusion blocks 16, while the side of mold 15... The high-temperature resistant sealing gasket 152 will also enter the mounting groove 200 at one end of the extrusion tube 2, thus forming a good sealing state. In this way, the installation process of the mold 15 is completed quickly and smoothly. When it is necessary to disassemble the mold 15, the operator only needs to operate the ring handle 22. The ring handle 22 will drive the rotating ring 21 to rotate on the extrusion tube 2. While the ring handle 22 is rotating, it will drive multiple rollers 24 to rotate through multiple connecting columns 23. The multiple rollers 24 will enter multiple inclined grooves 20 respectively and squeeze the extrusion block 16. This squeezing action will cause the extrusion block 16 to unfold again, thereby releasing the restriction of the slot 19 on the extrusion wheel 151. At this time, the mold 15 can be easily removed from the extrusion tube 2. This design effectively solves the problem of quick installation and disassembly of the mold 15.

[0027] Example: Figure 1 - Figure 3 As shown, the motor disassembly structure includes a limiting seat 4, which is fixedly connected to one side of a fixed seat 1. A dust cover 5 is fixedly connected to the outer side of one end of the limiting seat 4, and the dust cover 5 is fixedly connected to one side of the fixed seat 1. A circular groove 400 is formed inside the limiting seat 4, and a motor body 7 is placed inside the circular groove 400. A square block 8 is fixedly connected to the output end of the motor body 7. A square groove is opened at one end of the spiral auger 3, and the square block 8 is placed inside the square groove. A limiting frame 6 is fixedly connected to the outer side of the motor body 7. Multiple fixing grooves 600 are opened on the outer side of the limiting frame 6, and the limiting frame 6 is placed inside the limiting seat 4. The motor disassembly... The unloading structure also includes a rotating disk 9, which is rotatably connected to the outside of the limiting seat 4. A worm gear 10 is fixedly connected to the outside of the rotating disk 9, and a worm 11 is meshed with the outside of the worm gear 10. Both ends of the worm 11 pass through the inside of the dust cover 5 and are rotatably connected to the dust cover 5. A handle is installed at one end of the worm 11. Multiple arc-shaped grooves 12 are opened on the outside of the rotating disk 9. A sliding column 13 is slidably arranged inside the arc-shaped groove 12. A fixed rod 14 is installed at one end of the sliding column 13. Multiple sliding grooves are opened on the outside of the limiting seat 4. The multiple sliding grooves communicate with the inside of the limiting seat 4. The multiple fixed rods 14 are respectively arranged inside the multiple sliding grooves.

[0028] Specifically, when it is necessary to disassemble the motor body 7, the operator only needs to turn the throttle, which will drive the worm 11 to rotate. The worm 11 meshes with the worm wheel 10, and the worm wheel 10 drives the rotating disk 9 to rotate on the limit seat 4. During the rotation of the rotating disk 9, the multiple arc-shaped grooves 12 on its outer side will guide the multiple sliding columns 13 inside to slide. The sliding of the sliding column 13 in the arc-shaped groove 12 will cause the fixing rod 14 at one end to unfold, and the limit seat 4 will move out of the fixing groove 600. Therefore, the fixing effect on the motor body 7 is released. In this way, the motor body 7 can be quickly removed from the device, which is convenient for the operator to perform maintenance or replacement.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
