Description

Technical Field

[0001] The present application relates to the technical field of rubber processing, and particularly relates to a rubber processing extrusion device. Background Art

[0002] Rubber is a polymer material formed by the polymerization of a variety of high molecular organic compounds, with high elasticity, wear resistance and waterproof properties. It is divided into two categories: natural rubber and synthetic rubber. With the development of society, synthetic rubber has replaced natural rubber in many fields. During the production and processing of rubber, a corresponding extruder is required to produce and process rubber.

[0003] The applicant found through retrieval that the Chinese patent discloses "a rubber processing extrusion device" with the publication number "CN221873101U", which includes a base. One side of the top of the base is fixedly connected with a fixing plate. One side of the fixing plate is fixedly connected with an extrusion tube. One side of the extrusion tube is movably connected with an extrusion die head. The other side of the top of the extrusion tube is fixedly connected with a feeding hopper. The other side of the fixing plate is fixedly connected with a driving motor. The output end of the driving motor extends into the interior of the extrusion tube and is fixedly connected with a spiral feeding roller through a coupling. By setting the feeding assembly, the rubber raw materials in the feeding hopper are crushed by the rotation of the crushing teeth, and the residual rubber raw materials on the inner wall of the feeding hopper are reduced by using the scraper. Then, the crushed rubber raw materials are pressurized and conveyed into the extrusion tube by the rotation of the feeding screw rod, avoiding the inconvenience caused by the small space at the lower end of the feeding hopper and one side of the extrusion tube, resulting in unsmooth feeding or blockage of the rubber raw materials.

[0004] However, the shape of the rubber extruded by the existing extrusion device is limited, and the shape of the products produced by the rubber extrusion device is relatively single. For example, if rubber of other shapes needs to be extruded, different die molds need to be replaced, and the replacement method of the die mold is also relatively cumbersome. Summary of the Invention

[0005] Therefore, the present application provides a rubber processing extrusion device to solve the problem that the replacement of the die is relatively cumbersome in the prior art.

[0006] To achieve the above object, the present application provides the following technical solutions:

[0007] In a first aspect, it includes an extrusion barrel, an extrusion shaft rotatably connected to both sides of the inner wall of the extrusion barrel, a receiving block fixedly connected to one side of the surface of the extrusion barrel, and an output motor fixedly connected to the top surface of the receiving block. One side of the surface of the extrusion barrel is fixedly connected with a clamping structure, which can produce a clamping effect on the die inserted on one side of the surface. One side of the surface of the clamping structure is slidably connected with a die structure, which can be disassembled quickly and autonomously to adjust the shape of the rubber extrusion.

[0008] Optionally, the clamping structure includes an installation cylinder, a bidirectional lead screw, and threaded clamping blocks. The installation cylinder is fixedly connected to one side of the surface of the extrusion cylinder, and one end of the installation cylinder extends into the interior of the extrusion cylinder. Both ends of the bidirectional lead screw are rotatably connected to both sides of the inner wall of the installation cylinder, and both threaded clamping blocks are internally threaded to both sides of the rod wall of the bidirectional lead screw.

[0009] Optionally, the clamping structure further includes a control rod. The control rod is rotatably connected to one side of the surface of the installation cylinder, and one end of the control rod penetrates into the interior of the installation cylinder and is fixedly connected to one end of the bidirectional lead screw.

[0010] Optionally, the clamping structure further includes an insertion port, a limiting groove, and a through port. The insertion port is designed to penetrate through the interior of the installation cylinder. Both limiting grooves are opened on both sides of the inner wall of the insertion port. Both through ports are opened inside the installation cylinder and are located on both sides of the insertion port. At the same time, the two through ports are matched with the opposite ends of the two threaded clamping blocks.

[0011] Optionally, the die structure includes a die tube and a docking block. The die tube is slidably connected to the inner wall of the insertion port. Both docking blocks are fixedly connected to both sides of the surface of the die tube, and both docking blocks are respectively slidably connected to the inner walls of the two limiting grooves.

[0012] Optionally, the die structure further includes a card slot. Both card slots are opened on both sides of the surface of the die tube, and the inner walls of the two card slots are respectively slidably connected to the opposite ends of the two threaded clamping blocks.

[0013] Optionally, fixing grooves are opened on both sides of the top surface of the inner wall of the installation cylinder, and the inner walls of the two fixing grooves are respectively slidably connected to the top surfaces of the two threaded clamping blocks. Limiting blocks are fixedly connected to both sides of the rod wall of the bidirectional lead screw.

[0014] Optionally, a guiding block is fixedly connected to one side of the inner wall of the limiting groove.

[0015] Compared with the prior art, the present application has at least the following beneficial effects:

[0016] 1. By setting structures such as an installation cylinder, a bidirectional lead screw, threaded clamping blocks, a control rod, an insertion port, a limiting groove, a through port, a die tube, a docking block, and a card slot, when the device needs to replace the die, only the control rod needs to be rotated, so that the control rod drives the bidirectional lead screw to rotate, and then the bidirectional lead screw can drive the threaded clamping blocks on both sides to move relatively. The threaded clamping blocks will move out through the through port. At the same time, the opposite ends of the threaded clamping blocks will also move out of the card slot, thereby releasing the clamping effect. When replacing the new die tube, the position is regulated by the docking block, and rotating the control rod in the reverse direction will form a clamping effect, which can reduce the cumbersome effect during the die replacement work of the device and enable the device to enter the working state faster.

[0017] 2. By opening the plug interface, the die tube can be directly inserted into the interior of the installation barrel, so that the die is directly connected with the interior of the extrusion barrel through the plug interface, thereby producing an extrusion effect.

[0025] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0026] Embodiment 1

[0027] like Figures 1 to 4As shown in the figure, a rubber processing and extrusion device in the first aspect of the present invention includes an extrusion barrel 1, an extrusion shaft 2 rotatably connected to both sides of the inner wall of the extrusion barrel 1, a receiving block 3 fixedly connected to one side of the surface of the extrusion barrel 1, and an output motor 4 fixedly connected to the top surface of the receiving block 3. A clamping structure 5 is fixedly connected to one side of the surface of the extrusion barrel 1, which can produce a clamping effect on the die inserted on one side of the surface. A die structure 6 is slidably connected to one side of the surface of the clamping structure 5, which can be disassembled quickly and autonomously to adjust the shape of the rubber extrusion.

[0028] The technical effect achieved by the above embodiment is that the present invention enables the device, when the die needs to be replaced, only by rotating the control rod 504, the control rod 504 drives the bidirectional lead screw 502 to rotate, so that the bidirectional lead screw 502 drives the threaded clamping blocks 503 on both sides to move relatively. The threaded clamping blocks 503 will move out through the through hole 507. At the same time, the opposite ends of the threaded clamping blocks 503 will also move out of the clamping slots 603, thus releasing the clamping effect. When replacing the new die tube 601, by aligning the position through the docking block 602 and rotating the control rod 504 in the reverse direction, a clamping effect will be formed, which can reduce the cumbersome operation during the die replacement work of the device and enable the device to enter the working state faster.

[0029] Embodiment 2

[0030] As Figures 1 to 3 As shown in the figure, a rubber processing and extrusion device includes all the contents of Embodiment 1. In addition, the clamping structure 5 includes an installation cylinder 501, a bidirectional lead screw 502, and threaded clamping blocks 503. The installation cylinder 501 is fixedly connected to one side of the surface of the extrusion barrel 1, and one end of the installation cylinder 501 extends into the extrusion barrel 1. The two ends of the bidirectional lead screw 502 are rotatably connected to both sides of the inner wall of the installation cylinder 501. The interiors of the two threaded clamping blocks 503 are threadedly connected to both sides of the rod wall of the bidirectional lead screw 502. The clamping structure 5 further includes a control rod 504, which is rotatably connected to one side of the surface of the installation cylinder 501, and one end of the control rod 504 penetrates into the interior of the installation cylinder 501 and is fixedly connected to one end of the bidirectional lead screw 502. The clamping structure 5 further includes an insertion port 505, a limiting groove 506, and a through hole 507. The insertion port 505 is designed to penetrate through the interior of the installation cylinder 501. The two limiting grooves 506 are both opened on both sides of the inner wall of the insertion port 505. The two through holes 507 are both opened inside the installation cylinder 501 and are located on both sides of the insertion port 505. At the same time, the two through holes 507 are matched with the opposite ends of the two threaded clamping blocks 503.

[0031] The technical effects achieved by the above embodiments are as follows: By rotating the control rod 504, the control rod 504 drives the double-headed lead screw 502 to produce a rotating effect. While the double-headed lead screw 502 rotates, it drives the threaded clamping blocks 503 threadedly connected to both sides of the rod wall to form a relative displacement effect. However, when the two threaded clamping blocks 503 displace relative to each other, the relative ends of the threaded clamping blocks 503 will produce a self-in and out effect inside the through port 507, thereby achieving the effects of clamping and releasing clamping.

[0032] Embodiment Three

[0033] As Figure 2 and Figure 4 As shown, a rubber processing and extrusion device includes all the contents of Embodiment 1. In addition, the die structure 6 includes a die tube 601 and a docking block 602. The die tube 601 is slidably connected to the inner wall of the insertion port 505. Both docking blocks 602 are fixedly connected to both sides of the surface of the die tube 601, and both docking blocks 602 are respectively slidably connected to the inner walls of the two limiting grooves 506. The die structure 6 further includes clamping grooves 603. Both clamping grooves 603 are opened on both sides of the surface of the die tube 601, and the inner walls of the two clamping grooves 603 are respectively slidably connected to the relative ends of the two threaded clamping blocks 503.

[0034] The technical effects achieved by the above embodiments are as follows: Insert the die tube 601 into the inside of the limiting groove 506. During the insertion, the docking blocks 602 can be used to dock with the two limiting grooves 506, so that the installation effect of the die tube 601 can be more standardized. At the same time, the two clamping grooves 603 are paired with the relative ends of the two threaded clamping blocks 503.

[0035] Embodiment Three

[0036] As Figure 2 and Figure 3 As shown, a rubber processing and extrusion device includes all the contents of Embodiment 1. In addition, fixing grooves 7 are opened on both sides of the top surface of the inner wall of the mounting cylinder 501, and the inner walls of the two fixing grooves 7 are respectively slidably connected to the top surfaces of the two threaded clamping blocks 503. Limiting blocks 8 are fixedly connected to both sides of the rod wall of the double-headed lead screw 502, and a guiding block 9 is fixedly connected to one side of the inner wall of the limiting groove 506.

[0037] The technical effects achieved by the above embodiments are as follows: The opening of the fixing grooves 7 enables the tops of the two threaded clamping blocks 503 to be limited and slid inside; the limiting blocks 8 can limit the two threaded clamping blocks 503 from making excessive displacements; the setting of the guiding block 9 enables the rubber raw material inside the extrusion cylinder 1 to stably enter the inside of the die tube 601 through the limiting groove 506.

[0038] The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features). For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written out should also be regarded as falling within the scope described in this specification.
