Description

Technical Field

[0001] This utility model relates to the field of rubber compounding technology, specifically to a raw material feeding mechanism for a rubber mixing machine in rubber compounding production. Background Technology

[0002] Rubber mixing mills are indispensable mechanical equipment in the rubber industry, mainly used for processes such as hot refining, sheeting, breaking, plasticizing and mixing of rubber.

[0003] Rubber mixing mills play a central role in the production of rubber products, and their design and function are designed to meet various needs in the rubber processing process. Open-type and closed-type rubber mixing mills are two main types, each with its unique functions and application areas.

[0004] The raw material feeding process for the rubber mixing mill involves first adding raw rubber or other materials to the internal mixer. The raw materials are then fed into the gap between the two rotors under the pressure of the top bolt and the action of friction. Under the influence of different rotor speeds, the two rubber materials merge at different speeds at the top of the two rotors and then enter the gap between the two rotors. This cycle is repeated. After the internal mixer has been used for mixing, the raw materials are lifted by the lifting feeder and then enter the rubber mixing mill for further mixing.

[0005] When feeding material through the bucket of the elevator, the bucket is a fixed feeding point, which causes the raw material to accumulate on the mixing roller, prolonging the mixing time. In addition, the rubber material that has passed through the mixing roller needs to be manually held by one end and thrown towards the upper mixing roller for subsequent recycling. This is labor-intensive for workers, and when the rubber material is manually thrown towards the upper mixing roller, the other end of the rubber material is on the mixing roller, which may cause the worker's arm to be pulled into the machine, posing a safety hazard. Utility Model Content

[0006] The purpose of this utility model is to provide a raw material feeding mechanism for a rubber mixing machine in the production of compounded rubber, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A raw material feeding mechanism for a rubber mixing mill for producing compounded rubber includes a rubber mixing mill, an automatic displacement type feeding hoist is provided at the front of the rubber mixing mill, a circulating rubber mixing lifting component is provided at the front of the rubber mixing mill, the rubber mixing mill includes a frame, rubber mixing rollers are symmetrically connected on the frame, and a circulating rubber mixing roller is symmetrically connected on one side of the top of the rubber mixing rollers.

[0009] As a preferred embodiment of this utility model, the automatic displacement feeding hoist includes an electric CNC ground rail and a lifting feeding machine. The electric CNC ground rail is embedded parallel to the ground on the front side of the frame. Sliding blocks are symmetrically slidably connected to the electric CNC ground rail. A support frame is connected to the bottom of the lifting feeding machine. A connecting seat is connected to the bottom of the support frame. The connecting seat is connected to the symmetrically slidably connected sliding blocks on the electric CNC ground rail.

[0010] As a preferred embodiment of this utility model, when the hopper of the lifting feeder is tilted to discharge material, the discharge port of the hopper of the lifting feeder is located directly above the two rubber mixing rollers.

[0011] As a preferred embodiment of this utility model, the circulating rubber mixing and lifting assembly includes a drive motor and a lifting rod. The lifting rod is arranged in an L-shape and is located below the rubber mixing roller on the side away from the automatic displacement feeding hoist. A bushing is connected to one end of the lifting rod, and a shaft is connected through the bushing. The shaft is connected to the outer wall of the frame through a bearing seat. The output end of the drive motor is connected to the shaft located outside the bushing.

[0012] In a preferred embodiment of this utility model, when the drive motor drives the lifting rod to rotate, the lifting rod is located on the circulating rubber mixing roller.

[0013] As a preferred embodiment of this utility model, the electric CNC ground rail and the drive motor are electrically connected to the rubber mixing machine control equipment via wires.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In response to the problems mentioned in the background art, the automatic displacement feeding hoist of this application includes an electric CNC ground rail and a lifting feeding machine, which can automatically adjust the position of the hopper according to production needs, reduce the accumulation of raw materials on the rubber mixing rollers, and realize the precise movement of the hopper through the electric CNC ground rail. The hopper outlet of the lifting feeding machine is located directly above the two rubber mixing rollers, ensuring that the raw materials are evenly distributed on the rubber mixing rollers, avoiding local accumulation, and improving mixing efficiency.

[0016] The circulating rubber mixing and lifting assembly includes a drive motor and a lifting rod. The lifting rod has an L-shaped structure and is located below the mixing roller, away from the automatic displacement feeding hoist. The drive motor drives the lifting rod to rotate, lifting the rubber material falling from the mixing roller and transferring it to the circulating mixing roller. This achieves circulating rubber mixing, reduces manual intervention, improves production efficiency, reduces the need for manual handling of rubber material and throwing it towards the mixing roller, reduces the labor intensity of workers, and reduces the safety hazard of workers' arms being pulled into the machine when throwing rubber material towards the mixing roller, thus improving the safety of the production process.

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the embodiments of this utility model.

[0023] Example

[0024] All devices in this application adopt conventional models in the prior art, and the control method is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field, so this application will not explain it in detail.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a raw material feeding mechanism for a rubber mixing mill used in rubber compounding, comprising a rubber mixing mill 1, an automatic displacement feeding hoist 2 installed at the front of the rubber mixing mill 1, and a circulating rubber mixing lifting assembly 3 installed at the front of the rubber mixing mill 1. The rubber mixing mill 1 includes a frame 11, on which rubber mixing rollers 12 are symmetrically connected, and on one side of the top of the rubber mixing rollers 12, circulating rubber mixing rollers 13 are symmetrically connected. The automatic displacement feeding hoist 2 includes an electric numerically controlled ground rail 21 and a lifting feeding machine 22. 1. Parallel mounting on the ground in front of the frame 11, with symmetrical sliding blocks connected to the electric CNC ground rail 21, and a support frame 221 connected to the bottom of the lifting feeder 22, with a connecting seat 222 connected to the bottom of the support frame 221, and the connecting seat 222 connected to the symmetrical sliding blocks on the electric CNC ground rail 21; when the hopper of the lifting feeder 22 is tilted to discharge material, the hopper outlet of the lifting feeder 22 is located directly above the two rubber mixing rollers 12; the electric CNC ground rail 21 and the drive motor 31 are electrically connected to the control equipment of the rubber mixing machine 1 through wires.

[0026] It should be noted that, in this embodiment, the automatic displacement feeding hoist 2 includes an electric CNC ground rail 21 and a lifting feeding machine 22, which can automatically adjust the position of the hopper according to production needs, reduce the accumulation of raw materials on the rubber mixing rollers, and achieve precise movement of the hopper through the electric CNC ground rail 21. The hopper outlet of the lifting feeding machine 22 is located directly above the two rubber mixing rollers 12, ensuring that the raw materials are evenly distributed on the rubber mixing rollers and avoiding local accumulation.

[0027] Furthermore, when in use, the lifting feeder 22 is started. When the hopper of the lifting feeder 22 is lifted to the top and flipped, the electric CNC ground rail 21 drives the lifting feeder 22 to move through the slider. It can automatically adjust the position of the hopper according to production needs and reduce the accumulation of raw materials on the rubber mixing roller.

[0028] Furthermore, when the hopper of the lifting feeder 22 is lifted to the top, it is flipped to discharge material. At this time, the hopper outlet is located directly above the two rubber mixing rollers 12. This helps the raw material to enter directly between the rubber mixing rollers. With the automatic displacement, the raw material is evenly distributed on the rubber mixing rollers, avoiding local accumulation. This further ensures the even distribution of the raw material and avoids accumulation.

[0029] Please see Figure 1 , 2 4. The circulating rubber mixing and lifting assembly 3 includes a drive motor 31 and a lifting rod 32. The lifting rod 32 is arranged in an L-shape and is located below the rubber mixing roller 12 on the side away from the automatic displacement feeding hoist 2. One end of the lifting rod 32 is connected to a bushing 321, and a shaft 322 is connected through the bushing 321. The shaft 322 is connected to the outer wall of the frame 11 through a bearing seat. The output end of the drive motor 31 is connected to the shaft 322 located outside the bushing 321. When the drive motor 31 drives the lifting rod 32 to rotate, the lifting rod 32 is located on the circulating rubber mixing roller 13.

[0030] It should be noted that in this embodiment, the drive motor 31 can drive the lifting rod 32 to rotate. The lifting rod 32 has an L-shaped structure and is located below the mixing roller 12 on the side away from the automatic displacement feeding hoist 2. When the drive motor 31 starts, the lifting rod 32 lifts the rubber material on the mixing roller and transfers it to the circulating mixing roller 13, realizing the circulating mixing of the rubber material. Through the automated operation of the circulating mixing lifting component 3, the need for manual handling of the rubber material and throwing it onto the mixing roller is reduced. This not only reduces the labor intensity of the workers but also improves the continuity and efficiency of the production process.

[0031] Furthermore, through the coordinated operation of the automatic displacement feeding hoist 2 and the circulating rubber mixing lifting component 3, the entire rubber mixing process can achieve a higher degree of automation. This helps to shorten the rubber mixing time, improve production efficiency, reduce direct human intervention in the rubber mixing process, and correspondingly reduce safety hazards caused by improper operation, thereby improving the overall safety level of production.

[0032] It effectively solves the problems existing in the traditional material feeding process, such as raw material accumulation, long rubber mixing time, high labor intensity and safety hazards. These improvements not only improve production efficiency, but also provide operators with a safer and more convenient working environment.

[0033] The working process of this utility model:

[0034] In operation, the lifting and feeding machine 22 is started. When the hopper of the lifting and feeding machine 22 is lifted to the top and flipped, the electric CNC ground rail 21 drives the lifting and feeding machine 22 to move via the slider. The hopper of the lifting and feeding machine 22 flips to discharge material when it reaches the top. At this time, the hopper outlet is located directly above the two rubber mixing rollers 12, which helps the raw material to enter directly between the rubber mixing rollers. With automatic displacement, it ensures that the raw material is evenly distributed on the rubber mixing rollers and avoids local accumulation. When the rubber mixing rollers 12 discharge material, the drive motor 31 starts, and the rubber lifting rod 32 lifts the rubber material on the rubber mixing rollers and transfers it to the circulating rubber mixing roller 13, realizing the circulating rubber mixing. Through the automated operation of the circulating rubber mixing lifting component 3, the need for manual handling of rubber material and throwing it onto the rubber mixing rollers is reduced. This not only reduces the labor intensity of the workers, but also improves the continuity and efficiency of the production process.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
