Description

Technical Field

[0001] This utility model relates to the field of rubber processing technology, specifically a rubber mixing machine for rubber products. Background Technology

[0002] Rubber compounding is the core step in rubber processing. It is the process of transforming raw rubber and compounding agents (such as carbon black, vulcanizing agents, antioxidants, etc.) into a rubber compound with uniform properties that can meet the requirements of subsequent processing through mechanical action. Its core objective is to lay the foundation for the molding and vulcanization of rubber products through plasticizing (improving the plasticity of raw rubber) and mixing (making compounding agents uniformly dispersed).

[0003] Chinese Patent Publication No. CN 208118175 U discloses an automatic cleaning rubber mixing machine, which aims to solve the problem of convenient cleaning of the receiving tray of the rubber mixing machine. The key points of its technical solution are: it includes a rubber mixing machine body and a receiving tray set on the rubber mixing machine body for receiving rubber material. The feature is that it includes a cleaning plate set on the receiving tray for cleaning the rubber material, and the rubber mixing machine body is provided with a driving mechanism for driving the cleaning plate from one side of the receiving tray to the other side of the receiving tray. The aforementioned rubber mixing mill uses two rubber rollers to compress rubber, achieving the effect of rubber mixing. However, the distance between the two rubber rollers cannot be changed, so the space for rubber to pass through between the two rubber rollers is fixed. However, different rubber compounds have different hardness and viscosity. After adding compounding agents, the state of the rubber compound will also fluctuate (such as abnormal viscosity). The rubber rollers, whose distance cannot be changed, are prone to problems such as feed blockage, insufficient shearing, or excessive crushing. Utility Model Content

[0004] The purpose of this utility model is to provide a rubber mixing machine for rubber products, which uses two cylinders to drive two rotating frames to rotate, thereby driving the adjusting roller to move and changing the distance between the adjusting roller and the drive roller, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A rubber mixing machine for rubber products, including A drive roller assembly for open-milled rubber has an adjusting roller assembly on one side; a support assembly is provided below the drive roller assembly. The limiting assembly, used to limit the rubber, is located between the drive roller assembly and the adjusting roller assembly, and both ends of the limiting assembly are fixedly connected to the top of the side frame. The drive roller assembly includes a drive roller, and a scraper is provided on the side of the drive roller away from the support assembly. The side of the scraper away from the drive roller is fixedly connected to an adjustment plate. Mounting seats are fixedly connected to both ends of the adjustment plate, and the two mounting seats are respectively connected to the two ends of the connecting shaft by bolts. The adjusting roller assembly includes an adjusting roller, the two ends of which are rotatably connected to the ends of two rotating frames respectively; each of the two rotating frames is rotatably connected to a connector at the end away from the adjusting roller, and the two connectors are fixedly connected to the inner walls of the two ends of the side frame respectively. The bottom of the adjusting roller is equipped with a second scraper; the two rotating frames are rotatably connected to the telescopic rods of the two cylinders on the side away from the second scraper, and the ends of the two cylinders away from the rotating frames are rotatably connected to the inner walls of both ends of the side frame.

[0006] As a further technical solution of this utility model, the two ends of the drive roller are rotatably connected to the two ends of the side frame, and one end of the drive roller extends to the outside of the side frame and is fixedly connected to the output end of the reducer. The input end of the reducer is connected to the output shaft of the motor. Both the reducer and the motor are fixedly connected to the side frame. The two ends of the connecting shaft are fixedly connected to the inside of the two ends of the side frame.

[0007] As a further technical solution of this utility model, the side of the scraper away from the adjusting roller is fixedly connected to the adjusting plate. Both ends of the adjusting plate are fixedly connected to the mounting base. The two mounting bases are respectively connected to the two ends of the connecting shaft by bolts. The two ends of the connecting shaft are respectively fixedly connected to two rotating frames.

[0008] As a further technical solution of this utility model, the ends of the two rotating frames near the adjusting rollers are respectively attached to the two buffer seats, the ends of the two buffer seats away from the rotating frames are respectively fixedly connected to the two angle irons, and the two angle irons are respectively fixedly connected to the inner walls of both ends of the side frame.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a drive roller and an adjusting roller to process rubber. Two cylinders drive two rotating frames to rotate around a connecting piece, thereby moving the adjusting roller and changing its distance from the drive roller. This improves the operational flexibility of both the adjusting and drive rollers, enabling them to process rubber materials of different hardness and viscosity, as well as those with added additives, without causing problems such as feed blockage, insufficient shearing, or excessive crushing. Furthermore, when the rotating frame rotates and contacts the buffer seat, the buffer seat acts as a cushion, preventing the rotating frame and adjusting roller from shaking.

[0010] In this invention, after the rubber mixing process is completed, the two mounting seats 2 and 2 mounting seats 1 can be loosened to allow the adjusting plates 2 and 1 to rotate, thereby changing the angles of the scrapers 1 and 2. This allows the scraper 1 to be in contact with the drive roller and the scraper 2 to be in contact with the adjusting roller. At this time, the drive roller and the scraper 2 rotate, and the scrapers 1 and 2 can scrape off the residual material adhering to the drive roller and the adjusting roller. The residual material falls into the bottom box for centralized processing, which can ensure the cleanliness of the drive roller and the adjusting roller and facilitate the normal operation of subsequent rubber mixing processes.

The limiting component 3, which is used to limit the rubber, is located between the drive roller assembly 1 and the adjusting roller assembly 2, and both ends of the limiting component 3 are fixedly connected to the top of the side frame 5. The drive roller assembly 1 includes a drive roller 11. A scraper 16 is provided on the side of the drive roller 11 away from the support assembly 4. The side of the scraper 16 away from the drive roller 11 is fixedly connected to the adjustment plate 14. Mounting seats 17 are fixedly connected to both ends of the adjustment plate 14. The two mounting seats 17 are respectively connected to the two ends of the connecting shaft 15 by bolts. The adjusting roller assembly 2 includes an adjusting roller 21, the two ends of which are rotatably connected to the ends of two rotating frames 22 respectively; each of the two rotating frames 22 is rotatably connected to a connector 23 at the end away from the adjusting roller 21, and the two connectors 23 are fixedly connected to the inner walls of both ends of the side frame 5 respectively. The bottom of the adjusting roller 21 is provided with a scraper 25; the side of the two rotating frames 22 away from the scraper 25 is rotatably connected to the telescopic rod of the two cylinders 27 respectively, and the end of the two cylinders 27 away from the rotating frame 22 is rotatably connected to the inner walls of both ends of the side frame 5 respectively. The two ends of the drive roller 11 are rotatably connected to the two ends of the side frame 5, and one end of the drive roller 11 extends to the outside of the side frame 5 and is fixedly connected to the output end of the reducer 12.

The scraper 25 is fixedly connected to the adjustment plate 24 on the side away from the adjustment roller 21. Both ends of the adjustment plate 24 are fixedly connected to the mounting base 26. The two mounting bases 26 are respectively connected to the two ends of the connecting shaft 20 by bolts. The two ends of the connecting shaft 20 are respectively fixedly connected to the two rotating frames 22. The ends of the two rotating frames 22 near the adjusting roller 21 are respectively attached to the two buffer seats 29, and the ends of the two buffer seats 29 away from the rotating frames 22 are respectively fixedly connected to the two angle irons 28. The two angle irons 28 are respectively fixedly connected to the inner walls of both ends of the side frame 5. The limiting component 3 includes a crossbar 31, both ends of which are fixedly connected to connecting seats 33. The bottom of the two connecting seats 33 is fixedly connected to the top of both ends of the side frame 5 respectively. Both ends of the crossbar 31 are provided with limiting plates 32.

[0025] By adopting the above technical solution, the drive roller 11, together with the adjusting roller 21, can process rubber. The two cylinders 27 can drive the two rotating frames 22 to rotate around the connecting piece 23 as the center, thereby driving the adjusting roller 21 to move. This allows the adjusting roller 21 to change the distance between itself and the drive roller 11, improving the working flexibility of the adjusting roller 21 and the drive roller 11. This enables the adjusting roller 21 and the drive roller 11 to perform normal processing work even when processing rubber materials with different hardness and viscosity, as well as after adding compounding agents, preventing problems such as feed blockage, insufficient shearing, or excessive crushing. In addition, after the rotating frame 22 rotates and contacts the buffer seat 29, the buffer seat 29 can play a buffering role, preventing the rotating frame 22 and the adjusting roller 21 from shaking.

[0026] In this embodiment, both limiting plates 32 are located between the drive roller 11 and the adjusting roller 21; the ends of the two limiting plates 32 near the crossbar 31 are respectively connected to the two L-shaped plates 34 through multiple handle bolts 36; each of the two L-shaped plates 34 has an integral sleeve 35 in the middle of the side near the crossbar 31, and the two sleeves 35 are respectively sleeved to both ends of the crossbar 31, and the two sleeves 35 are connected to the crossbar 31 through handle bolts 36.

The input end of the reducer 42 is connected to the output shaft of the motor 43. Both the motor 43 and the reducer 42 are fixedly connected to the side frame 5. The lower end of the side frame 5 is provided with a bottom box 6, which is located below the drive roller 11.

[0027] By adopting the above technical solution, after the rubber mixing is completed, the two mounting seats 26 and 17 can be loosened to allow the adjusting plates 24 and 14 to rotate, thereby changing the angles of the scrapers 16 and 25. This allows the scraper 16 to be in contact with the drive roller 11 and the scraper 25 to be in contact with the adjusting roller 21. At this time, the drive roller 11 and the scraper 25 rotate, and the scrapers 16 and 25 can scrape off the residual material adhering to the drive roller 11 and the adjusting roller 21. The residual material falls into the bottom box 6 for centralized processing, which can ensure the cleanliness of the drive roller 11 and the adjusting roller 21 and facilitate the normal operation of subsequent rubber mixing.

[0028] The working principle of this utility model is as follows: the drive roller 11, together with the adjusting roller 21, can process rubber. The two cylinders 27 can drive the two rotating frames 22 to rotate around the connecting piece 23, thereby driving the adjusting roller 21 to move. This allows the adjusting roller 21 to change the distance between itself and the drive roller 11, improving the working flexibility of the adjusting roller 21 and the drive roller 11. This enables the adjusting roller 21 and the drive roller 11 to process rubber materials of different hardness and viscosity, as well as rubber materials with added compounding agents, and to perform normal processing work, preventing problems such as feed blockage, insufficient shearing, or excessive crushing. In addition, after the rotating frame 22 rotates and contacts the buffer seat 29, the buffer seat 29 can play a buffering role, preventing the rotating frame 22 and the adjusting roller 21 from shaking. After the rubber mixing process is completed, by loosening the two mounting seats 26 and 17, the adjusting plates 24 and 14 can be rotated, thereby changing the angle of the scrapers 16 and 25. This allows the scraper 16 to be in contact with the drive roller 11 and the scraper 25 to be in contact with the adjusting roller 21. At this time, the drive roller 11 and the scraper 25 rotate, and the scrapers 16 and 25 can scrape off the residual material adhering to the drive roller 11 and the adjusting roller 21. The residual material falls into the bottom box 6 for centralized processing, which ensures the cleanliness of the drive roller 11 and the adjusting roller 21 and facilitates the normal operation of subsequent rubber mixing.
