Description

Technical Field

[0001] This utility model relates to the field of rubber powder conveying technology, and in particular to a rubber degradation unit with a material conveying and residue prevention structure. Background Technology

[0002] In the production of recycled rubber, the rubber degradation unit needs to complete the transfer of rubber powder from the external feed end to the high-speed stirring and heating mechanism, and then to the low-speed stirring and heat preservation mechanism. The material residue problem in this process directly affects the production efficiency and product purity. Residual rubber powder not only causes raw material waste, but may also adhere to the feed inlet and the inner wall of the connecting pipe. After long-term accumulation, it will contaminate subsequent batches of products and even block the channel, causing the unit to shut down. Therefore, the anti-residue design in the material conveying process is the core requirement for unit optimization.

[0003] Existing patent CN221619402U discloses a degradation unit for reclaimed rubber. Its core technology utilizes a "high-speed stirring and heating mechanism and a low-speed stirring and heat preservation mechanism" to achieve staged degradation of rubber powder. The two mechanisms are connected only by a valved connecting pipe. However, this solution has a key flaw: it lacks a dedicated material conveying mechanism for rubber powder transport. When rubber powder is fed from the outside into the high-speed mixing tank, the lack of a directional guiding structure makes it prone to accumulating residues at the inlet. When rubber powder is transferred from the high-speed mixing tank to the low-speed mixing tank, it relies solely on natural flow through the connecting pipe without any pushing or scraping structure. This results in rubber powder easily adhering to the inner wall of the connecting pipe, forming residues and failing to meet the requirements for continuous and clean production. Utility Model Content

[0004] The technical problem to be solved by this invention is that the existing devices have the disadvantage that rubber powder is easy to accumulate and adhere. To address this, we propose a rubber degradation unit with a material conveying and residue prevention structure.

[0005] To achieve the above objectives, this application adopts the following technical solution: a rubber degradation unit with a material conveying and residue prevention structure, comprising a connecting pipe, a drive motor installed at one end of the connecting pipe, the drive motor being slidably connected to the inner wall of the connecting pipe, a conveying assembly built into the connecting pipe, the conveying assembly including a drive roller, one end of the drive roller being fixedly connected to the output end of the drive motor, multiple spiral plates being fixedly sleeved on the surface of the drive roller, a rotating disk being sleeved and fixed at the end of the drive roller away from the drive motor, multiple protrusions being fixedly connected to the side of the rotating disk away from the spiral plates, a fixed disk being provided on the side of the rotating disk away from the spiral plates, the fixed disk being fixedly connected to the inner wall of the connecting pipe around its perimeter, multiple grooves matching the protrusions being opened on the side of the fixed disk near the rotating disk, and a return spring being provided between the rotating disk and the fixed disk.

[0006] Preferably, a plurality of fixing rings are fixedly sleeved on the surface of the connecting pipe, and a support frame is fixedly sleeved on one end of the connecting pipe.

[0007] Preferably, a feed funnel is fixedly connected to the top of the connecting pipe.

[0008] Preferably, the reset spring is fitted with positioning cylinders at both ends, and a rotating bearing is fitted with the surface of the positioning cylinders.

[0009] Preferably, a positioning ring groove is provided on one side of the rotating disk, and the outer ring wall of a rotating bearing is fixedly connected to the inner wall of the positioning ring groove.

[0010] Preferably, another rotating bearing has a fixing bracket fixedly fitted to its outer ring wall, and the fixing bracket is fixedly connected to the inner wall of the connecting pipe.

[0011] Preferably, the protrusion is slidably connected to the inner wall of the groove.

[0012] Preferably, a material pipe is fixedly connected to the side of the rotating disk away from the spiral plate, and the end of the material pipe away from the rotating disk extends through the fixed disk to the output end of the connecting pipe.

[0013] The technical effects and advantages of this utility model are as follows: This utility model's rubber degradation unit uses a connecting pipe as its core, combined with a drive motor, a feeding hopper, and conveying components (drive roller and multi-layer spiral plate) to form a basic conveying system. It also features an innovative anti-residue structure, effectively addressing industry pain points. The drive motor rotates the drive roller and spiral plate, and combined with the feeding hopper, it achieves directional material conveying, preventing disorderly accumulation at the feed inlet. The core of its anti-residue mechanism lies in: a rotating disc protrusion at the end of the drive roller slides into a groove on the inner wall of the connecting pipe's fixed disc. When the protrusion enters the groove, it drives the drive roller and spiral plate to move laterally, scraping away residue from the pipe wall; a return spring (equipped with a rotating bearing to ensure operation) between the rotating disc and the fixed disc pushes the components back to their original position after the protrusion disengages from the groove, achieving cyclic scraping. This design specifically addresses the shortcomings of existing patents. Previously, adhesive powder tended to accumulate at the feed inlet and remain inside the connecting pipes. This unit, however, combines "spiral plate directional conveying and lateral scraping" to prevent material accumulation at the feed inlet and continuously clean residue from the pipe walls. Ultimately, this improves material utilization, reduces raw material waste, lowers cleaning and maintenance difficulty, and meets the high-efficiency and cleanliness requirements of continuous industrial production.

Detailed Implementation

[0016] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0017] Reference Figures 1 to 5 As shown, this utility model provides a technical solution: a rubber degradation unit with a material conveying and residue prevention structure, including a connecting pipe 1, multiple fixing rings 101 fixedly sleeved on the surface of the connecting pipe 1, a support frame 102 fixedly sleeved on one end of the connecting pipe 1, a drive motor 2 installed at one end of the connecting pipe 1, the drive motor 2 being slidably connected to the inner wall of the connecting pipe 1, a feeding funnel 103 fixedly connected to the top of the connecting pipe 1, a conveying assembly 3 built into the connecting pipe 1, the conveying assembly 3 including a drive roller 301, one end of the drive roller 301 being fixedly connected to the output end of the drive motor 2, and a multi-layer spiral plate 302 fixedly sleeved on the surface of the drive roller 301. The rubber degradation unit uses the connecting pipe 1 as the core conveying channel, the drive motor 2 installed at one end of the connecting pipe 1 is the power source, and the drive motor 2 is slidably connected to the inner wall of the connecting pipe 1, reserving space for the movement of subsequent components. When the drive motor 2 starts to run, its output end directly drives the built-in conveying component 3 to run. The drive roller 301 in the conveying component 3 will rotate synchronously with the drive motor 2. The multi-layer spiral plate 302 fixedly sleeved on the surface of the drive roller 301 will generate propulsion force during rotation, which will transport the material entering from the feed hopper 103 to the output end of the connecting pipe 1, thus initially realizing the directional transfer of the material.

[0018] A rotating disk 303 is fixedly sleeved at the end of the drive roller 301 away from the drive machine 2. Multiple protrusions 304 are fixedly connected to the side of the rotating disk 303 away from the spiral plate 302. A fixed disk 306 is provided on the side of the rotating disk 303 away from the spiral plate 302. The fixed disk 306 is fixedly connected to the inner wall of the connecting pipe 1 around its perimeter. Multiple grooves 307 matching the protrusions 304 are opened on the side of the fixed disk 306 near the rotating disk 303. The protrusions 304 are slidably connected to the inner wall of the grooves 307. Correspondingly, a fixed disk 306 is fixed on the inner wall of the connecting pipe 1. The fixed disk 306 is provided with grooves 307 matching the shape and number of the protrusions 304 on the side of the fixed disk 306 near the rotating disk 303. The protrusions 304 can slide against the inner wall of the grooves 307. When the drive roller 301 drives the rotating disk 303 to rotate, the protrusion 304 on the rotating disk 303 will move in a circular motion along with it. During the motion, the protrusion 304 will continuously enter and exit the groove 307. When the protrusion 304 enters the groove 307, the groove 307 exerts a lateral limiting force on the protrusion 304. This force will drive the rotating disk 303 to move laterally towards the fixed disk 306. The rotating disk 303 is fixedly connected to the drive roller 301, which in turn drives the drive roller 301 to move laterally synchronously. When the protrusion 304 exits the groove 307, the lateral limiting force disappears. This lateral movement of the drive roller 301 will drive the multi-layer spiral plate 302 on its surface to move laterally synchronously. Since the spiral plate 302 is close to the inner wall of the connecting pipe 1, the edge of the spiral plate 302 will scrape the inner wall of the connecting pipe 1 during the lateral movement, scraping off the adhesive powder residue adhering to the pipe wall and preventing the material from adhering and accumulating during the conveying process.

[0019] Furthermore, a return spring 308 is provided between the rotating disk 303 and the fixed disk 306. Positioning cylinders 309 are fixedly fitted onto both ends of the return spring 308. Rotary bearings 310 are fixedly fitted onto the surface of the positioning cylinders 309. A positioning ring groove 311 is provided on one side of the rotating disk 303. The outer ring wall of one rotary bearing 310 is fixedly connected to the inner wall of the positioning ring groove 311. A fixing bracket 312 is fixedly fitted onto the outer ring wall of the other rotary bearing 310. The fixing bracket 312 is fixedly connected to the inner wall of the connecting pipe 1. A material pipe 305 is fixedly connected to the side of the rotating disk 303 away from the spiral plate 302. The end of the material pipe 305 away from the rotating disk 303 extends through the fixed disk 306 to the output end of the connecting pipe 1. To ensure that the boss 304 can continuously cooperate with the groove 307 to achieve the scraping action, a return spring 308 is provided between the rotating disk 303 and the fixed disk 306. The design of the rotary bearing 310 ensures the installation stability of the return spring 308 without affecting the operation of the rotating components. When the boss 304 enters the groove 307 and drives the rotating disk 303 to move laterally towards the fixed disk 306, the return spring 308 is compressed and generates elastic potential energy. When the boss 304 disengages from the groove 307, the return spring 308 releases its elastic potential energy, pushing the rotating disk 303 to return to its original position away from the fixed disk 306, thereby driving the boss 304 back to its initial position, preparing for the next entry into the groove 307. This reset action ensures that the boss 304 can repeatedly cooperate with the groove 307, allowing the spiral plate 302 to continuously generate a lateral scraping action.

[0020] This unit specifically addresses the key shortcomings of existing patents. Existing patents lack a dedicated mechanism for conveying adhesive powder, leading to easy accumulation at the inlet and residue within the connecting pipe 1. This unit completely solves this problem by combining the propulsion and lateral scraping of multi-layer spiral plates 302: Firstly, the directional conveying of the feed funnel 103 with the spiral plates 302 prevents disorderly accumulation of material at the inlet, achieving precise material introduction; secondly, the cooperation of the protrusion 304 and groove 307 drives the spiral plates 302 to laterally scrape, and the cyclical reset of the return spring 308 continuously removes material residue from the inner wall of the connecting pipe 1, ensuring a clean pipe wall after each conveying operation and meeting the requirements of continuous and clean production. This allows the unit to achieve efficient conveying while significantly improving material utilization, reducing raw material waste due to residue, and lowering the difficulty of subsequent cleaning and maintenance, making it more suitable for the actual needs of continuous industrial production.

[0021] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
