Description

Technical Field

[0001] This utility model relates to the field of rubber mixing equipment technology, specifically a raw material pre-dispersion device for rubber sheet production. Background Technology

[0002] After all raw materials pass inspection, they are batched according to the required weight in the formula. The raw materials are weighed manually, and dust will be generated during the weighing process, resulting in fugitive emissions. The batching process uses manual feeding to add block rubber, powdered fillers, and additives for mixing.

[0003] According to the internal mixer mechanism of a publicized internal mixer (publication number: CN216992631U), the above application has an integrated charging and feeding structure for plasticizing and mixing rubber, as well as a matching independent temperature control device, and a high-efficiency power drive device. In fact, the overall internal mixer mechanism has a good effect on rubber plasticizing and mixing.

[0004] However, in actual use, the above-mentioned equipment, which puts block rubber, powdered fillers and additives into the mixing box from one side without a corresponding dispersion mechanism, is prone to raw material accumulation, which affects the subsequent processing effect. In view of this, we propose a raw material pre-dispersion device for rubber sheet production. Summary of the Invention

[0005] The purpose of this invention is to provide a pre-dispersion device for raw materials in the production of rubber sheets, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material pre-dispersion device for rubber sheet production, comprising a mixing chamber, a feeding box fixedly installed on the upper surface of the mixing chamber, a feeding inclined block fixedly installed on the arc surface of the feeding box, a dispersion mechanism disposed inside the feeding box, and an auxiliary mechanism disposed inside the feeding box, the dispersion mechanism comprising: The motor is fixedly mounted on the upper surface of the feeding box, and a rotating shaft is fixedly mounted on the output end of the motor. A spiral blade is fixedly mounted on the arc surface of the rotating shaft. A conical platform is fixedly mounted on the lower surface of a rotating shaft. An inclined protrusion is fixedly mounted on the arc surface of the conical platform, and a reinforcing frame is rotatably connected to the lower surface of the conical platform.

[0007] Preferably, the auxiliary mechanism includes a connecting rod, one end of which is fixedly connected to the inner wall of the feeding box, and the other end of which is fixedly connected to a guide block, the surface of which is fixedly fitted with a ring.

[0008] Preferably, the number of guide blocks is set to several, and the several guide blocks are arranged in a circular array inside the feeding box. The multiple guide blocks facilitate guiding part of the raw material to the bottom center of the feeding box for uniform dispersion.

[0009] Preferably, the lower end of the guide block is an inclined arc surface, and the lower end of the guide block points to the center of the rotating shaft, so that part of the raw material is guided to the center of the lower end through the guide block.

[0010] Preferably, the end of the reinforcing frame is fixedly installed on the inner wall of the feeding box, thereby ensuring stable support for the conical platform.

[0011] Preferably, the feeding box is formed by stacking a cylindrical box and a square box, and the end of the connecting rod away from the guide block is fixedly installed on the inner wall of the square box.

[0012] Preferably, the inclined protrusion is fixedly installed on the arc surface of the conical platform in a curved shape, and the number of inclined protrusions is set to several. The several inclined protrusions are fixedly installed on the arc surface of the conical platform in a circumferential array. The arrangement of multiple inclined protrusions facilitates the guidance of raw materials.

[0013] Compared with the prior art, this utility model provides a raw material pre-dispersion device for rubber sheet production, which has the following beneficial effects: 1. This raw material pre-dispersion device for rubber sheet production has a dispersion mechanism. The raw material enters the feeding box from the inclined surface of the feeding slab. The motor drives the rotating shaft to rotate, and the spiral blades uniformly disperse the raw material and guide it to the surface of the conical table. As the conical table rotates, the raw material is protruded along the inclined surface and, under the action of centrifugal force, is uniformly pre-dispersed from the conical table and falls into the interior of the mixing box to prevent accumulation and affect the subsequent processing effect.

[0014] 2. The raw material pre-dispersion device for rubber sheet production is equipped with an auxiliary mechanism and a guide block. The guide block guides some of the raw material falling from the conical platform, promoting the raw material to fall onto the vertical lower surface of the conical platform, thus improving the dispersion effect.

[0017] like Figures 1-4 As shown, this utility model provides a technical solution: a pre-dispersion device for raw materials in rubber sheet production, including a mixing box 1, a feeding box 2 fixedly installed on the upper surface of the mixing box 1, a feeding inclined block 5 fixedly installed on the arc surface of the feeding box 2, a dispersion mechanism 3 and an auxiliary mechanism 4 are provided inside the feeding box 2, and the dispersion mechanism 3 includes a motor 301, a rotating shaft 302, a spiral blade 303, a conical platform 304, an inclined protrusion 305, and a reinforcing frame 306.

[0018] In one embodiment of this utility model, a motor 301 is fixedly installed on the upper surface of the feeding box 2, a rotating shaft 302 is fixedly installed at the output end of the motor 301, a spiral blade 303 is fixedly installed on the arc surface of the rotating shaft 302, a conical platform 304 is fixedly installed on the lower surface of the rotating shaft 302, a sloping protrusion 305 is fixedly installed on the arc surface of the conical platform 304, and a reinforcing frame 306 is rotatably connected to the lower surface of the conical platform 304.

[0019] In addition, the auxiliary mechanism 4 includes a connecting rod 401. One end of the connecting rod 401 is fixedly connected to the inner wall of the feeding box 2, and the other end of the connecting rod 401 is fixedly connected to a guide block 402. A ring 403 is fixedly installed on the surface of the guide block 402. Several guide blocks 402 are arranged in a circumferential array inside the feeding box 2. The multiple guide blocks 402 facilitate guiding some raw materials to the bottom center of the feeding box 2 for uniform dispersion.

[0020] In this embodiment of the invention, the lower end of the guide block 402 is inclined and arc-shaped, and the lower end of the guide block 402 points to the center of the rotating shaft 302, guiding part of the raw material to the center of the lower end through the guide block 402. The end of the reinforcing frame 306 is fixedly installed on the inner wall of the feeding box 2, thereby ensuring stable support for the conical platform 304. The feeding box 2 is composed of a cylindrical and a square box stacked on top of each other, and the end of the connecting rod 401 away from the guide block 402 is fixedly installed on the inner wall of the square box. The inclined protrusion 305 is curved and fixedly installed on the arc surface of the conical platform 304. Several inclined protrusions 305 are arranged in a circumferential array and fixedly installed on the arc surface of the conical platform 304. The arrangement of multiple inclined protrusions 305 facilitates the guidance of raw materials.

[0021] In this invention, during use, the raw material enters the feeding box 2 from the unloading surface of the feeding inclined block 5. The motor 301 drives the rotating shaft 302 to rotate, and the spiral blades 303 evenly disperse the raw material and guide it to the surface of the conical platform 304. As the conical platform 304 rotates, the raw material falls evenly from the conical platform 304 into the interior of the mixing box 1 under the action of centrifugal force along the inclined protrusion 305, preventing accumulation and affecting the subsequent processing effect.

[0022] Furthermore, a guide block 402 is provided to guide some of the raw material falling from the conical stage 304 to the vertical lower surface of the conical stage 304, thereby promoting the dispersion effect.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
