Description

Technical Field

[0001] The utility model relates to the field of rubber compound processing, and more specifically, to a composite extrusion device for rubber compound production. Background Art

[0002] With the rapid development of the rubber industry, the market's requirements for the performance and appearance of rubber products are increasing day by day. The traditional single compound extrusion method has been difficult to meet the complex and changeable production needs. As an advanced rubber processing technology, the composite extrusion technology can produce rubber products with excellent performance and colorful appearance by combining multiple rubber compounds with different colors and properties.

[0003] After retrieval, in the prior art, the Chinese patent with the patent publication number CN217495115U discloses "a rubber raw material extrusion device for rubber preparation and processing, including a bottom plate and a fixed box installed on the top surface of the bottom plate. A feeding box is installed on the top surface of the fixed box, and an extrusion cylinder is installed inside the fixed box. One end of the extrusion cylinder is connected to a driving motor, and the other end of the extrusion cylinder is connected to a fixed ring. The inside of the fixed ring is connected to an extrusion die head, and a number of elastic clamping rods are equidistantly installed on one side of the fixed ring. A clamp is clamped between the outer sides of the number of elastic clamping rods. The clamp is composed of two connecting hoops, and a hinge is provided at the bottom connection of the two connecting hoops. Fixed blocks are provided at the top connections of the two connecting hoops, and a fastening bolt is connected between the side walls of the two fixed blocks passing through; this utility model can facilitate the replacement of the extrusion die head and avoid the blockage of the feeding cylinder during feeding", but there are still the following defects:

[0004] (1) Although this device can play a role in conveying rubber, when in use, the rubber is extruded by the push plate descending and then passing through the porous mesh plate to extrude the rubber into a long strip shape. However, multiple long strip-shaped rubbers will enter the inside of the extrusion cylinder together, and thus the phenomenon of rubber blockage in the extrusion cylinder will occur. Therefore, it still needs to be improved.

[0005] (2) Although this device can support the outside of the extrusion cylinder during use, it cannot adjust the position of the device supporting the extrusion cylinder, and thus cannot accurately support the required position.

[0006] Therefore, we make improvements on this and propose a composite extrusion device for rubber compound production. Content of the Utility Model

[0007] The purpose of the present utility model is to address the problem that in a composite extrusion device for rubber compound production currently in use, when the push plate descends, the rubber is extruded, causing the rubber to pass through a perforated mesh plate and be extruded into long strips. However, multiple long strips of rubber enter the interior of the extrusion barrel together, resulting in the problem of rubber clogging the extrusion barrel.

[0008] To achieve the above-mentioned utility model purpose, the present utility model provides the following technical solutions:

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0032] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments may be combined with each other.

[0033] It should be noted that like reference numerals and letters refer to like items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] As Figures 1-8 shown, this embodiment provides a composite extrusion device for rubber compound production, which includes a box body 1. An extrusion mechanism 2 for extruding rubber compound is arranged inside the box body 1, and a support assembly 3 for supporting the box body 1 is arranged at the bottom of the box body 1.

[0035] The extrusion mechanism 2 includes a feed inlet 201, a hydraulic cylinder 202, a pressure plate 203, a screen plate 204, a first motor 205, a first gear 206, a second gear 207, a first crushing roller 208, a second crushing roller 209, a conveying pipe 210, a second motor 211, a screw conveyor 212, a heating wire 213, and a composite die head 214. The feed inlet 201 is opened on the side wall of the box body 1. The hydraulic cylinder 202 is fixedly connected to the top of the box body 1. The pressure plate 203 is fixedly connected to the output end of the hydraulic cylinder 202. The screen plate 204 is arranged inside the box body 1. The first motor 205 is arranged outside the box body 1. The first gear 206 is fixedly connected to the output end of the first motor 205. The second gear 207 is rotatably connected to the side wall of the box body 1. The first crushing roller 208 and the second crushing roller 209 are respectively fixedly connected to the side walls of the first gear 206 and the second gear 207. The conveying pipe 210 is communicatively arranged at the bottom of the box body 1. The second motor 211 is arranged outside the conveying pipe 210. The screw conveyor 212 is fixedly connected to the output end of the second motor 211. The heating wire 213 is arranged inside the wall of the conveying pipe 210. The composite die head 214 is arranged at one end of the conveying pipe 210. The first gear 206 meshes with the second gear 207. The screw conveyor 212 is located inside the conveying pipe 210. During use, the hydraulic cylinder 202 drives the pressure plate 203 to descend, thereby extruding the material into a long strip. Then, the first motor 205 drives the first gear 206 to rotate. The first gear 206 meshes with the second gear 207, so that the first crushing roller 208 and the second crushing roller 209 rotate, thereby crushing the material and effectively preventing the conveying pipe 210 from being blocked.

[0036] As Figure 3As shown in the figure, considering the lack of support for the conveying pipe 210, the support assembly 3 includes a support platform 301, a bidirectional lead screw 302, a first support plate 303, and a second support plate 304. The support platform 301 is arranged at the bottom of the conveying pipe 210. The bidirectional lead screw 302 is rotatably connected to the side wall of the support platform 301. The first support plate 303 and the second support plate 304 are respectively threadedly connected to both ends of the bidirectional lead screw 302. The tops of the first support plate 303 and the second support plate 304 are in close contact with the outer wall of the conveying pipe 210. During use, the bidirectional lead screw 302 is rotated to change the positions of the first support plate 303 and the second support plate 304, thereby supporting different positions of the conveying pipe 210.

[0037] As Figure 1 shown in the figure, considering the poor stability of the box body 1, a connecting rod 4 is bolted to the top of the support platform 301, a support leg 5 is bolted to the bottom of the support platform 301, and a support rod 6 is bolted to the bottom of the box body 1. The top of the connecting rod 4 is bolted to the bottom of the box body 1. During use, the box body 1 is connected to the support platform 301 through the connecting rod 4, and at the same time, the support rod 6 is used to support one end of the bottom of the box body 1, greatly improving the stability of the box body 1.

[0038] As Figure 8 shown in the figure, considering the inconvenience of replacing the composite die head 214, a first flange 7 is welded to the outer wall of the composite die head 214, a second flange 8 is welded to one end of the conveying pipe 210, and bolts 9 are threadedly connected to the interiors of both the first flange 7 and the second flange 8. During use, if the composite die head 214 needs to be replaced, the bolts 9 are directly unscrewed, then a new composite die head 214 is replaced, and then the bolts 9 are screwed in again.

[0039] As Figure 1 shown in the figure, considering the inconvenience of knowing whether the interior of the box body 1 is blocked, a rectangular groove 10 is formed in the side wall of the box body 1, and a transparent glass plate 11 is fixedly connected to the interior of the rectangular groove 10. The transparent glass plate 11 is made of tempered glass. During use, the interior situation of the box body 1 can be conveniently observed through the transparent glass plate 11. If the material is blocked, a timely reaction can be made.

[0040] As Figure 3 shown in the figure, considering that some materials will accumulate on the inner bottom wall of the box body 1, a guide plate 12 for guiding the processed rubber material is fixedly connected to the inner bottom wall of the box body 1. The guide plate 12 is made of stainless steel. During use, the guide plate 12 can concentrate and guide the materials into the interior of the conveying pipe 210 to prevent material residues.

[0041] As Figure 1As shown in the figure, considering that when adding materials, the user's hand enters the feeding port 201, a guiding pipe 13 is bolted to one side of the box body 1. One end of the guiding pipe 13 is communicated with the feeding port 201. When in use, adding materials into the interior of the guiding pipe 13 can prevent the user's hand from entering the feeding port 201, thereby avoiding safety accidents.

[0042] Specifically, when the composite extrusion device for rubber compound production is in use: Add materials into the interior of the guiding pipe 13, then connect the first motor 205, the heating wire 213, and the second motor 211 to an external power source. Then, the heating wire 213 first pre-heats the interior of the conveying pipe 210. Then, start the first motor 205 and the second motor 211. Next, the hydraulic cylinder 202 drives the pressing plate 203 to descend, so that the materials are extruded on the mesh plate 204, and the materials are extruded into long strips. Then, the first motor 205 drives the first gear 206 to rotate. The first gear 206 meshes with the second gear 207, so that the first crushing roller 208 and the second crushing roller 209 rotate in different directions, and then the long strip-shaped materials are fully crushed, reducing the possibility of material blockage. Then, the materials are guided by the guiding plate 12 into the interior of the conveying pipe 210. At this time, the temperature inside the conveying pipe 210 will rise. Then, the second motor 211 drives the auger 212 to rotate, so that the materials are discharged from the composite die head 214. When the conveying pipe 210 conveys materials inside, the first support plate 303 and the second support plate 304 can support the conveying pipe 210, thereby improving the stability of the conveying pipe 210 when conveying materials.

[0043] All technical features in this embodiment can be freely combined according to actual needs.

[0044] The above embodiment is a preferred implementation scheme of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
