Description

Technical Field

[0001] The utility model relates to the technical field of rubber product processing, in particular to a rubber processing device. Background Art

[0002] Rubber processing is the process of making rubber into rubber products. The basic process of processing various rubber products includes plasticizing, mixing, calendering or extrusion, molding and vulcanization. Each process has different requirements for the product and is combined with several auxiliary operations. Rubber mixing is an important link in the rubber processing process. It is usually mixed by an open mixer or internal mixer. The main purpose is to evenly disperse various compounding agents in the rubber to obtain a good performance mixed rubber. Through the shearing and extrusion in the mixing process, the rubber molecular chain is broken and reorganized to a certain extent, improving the fluidity and plasticity of the rubber.

[0003] After searching, in the prior art, Chinese Patent Publication No.: CN218875952U discloses an open mixing mill, including two frames, two open mixing rollers rotatably arranged between the two frames, and also including a cold air device arranged on one side of one of the frames for generating cold air, and a cold supply pipe arranged between the two frames and located on one side of the open mixing roller for conveying the cold air generated by the cold air device. The cold air device generates cold air, and the cold supply pipe conveys the cold air generated by the cold air device. Since one end of the cold supply pipe is connected to the cold air device and a sealing plug is arranged at the other end of the cold supply pipe, the cold spray device sprays the cold air in the cold supply pipe onto the open mixing rollers, so as to cool down the open mixing rollers. After the two open mixing rollers have been refined for a long time, the open mixing rollers can be cooled down, and it is not easy to produce cooked rubber, thereby improving the quality of refining and greatly reducing the situation where the open mixing mill cannot produce normally.

[0004] But this device still has the following defects:

[0005] In order to improve the performance of rubber products, multiple compounding agents such as vulcanizers, accelerators, activators and reinforcing agents need to be added to the mixed rubber during the mixing process. The operator is required to evenly sprinkle the compounding agents on the surface of the mixed rubber during the rubber turning process. The accuracy is difficult to grasp. If the compounding agents are sprinkled too concentratedly, the number of rubber turning times needs to be increased, which directly affects the processing efficiency and increases the labor intensity of the operators. The device does not solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figures 1 to 6 , the utility model provides a rubber processing device:

[0031] In this embodiment, if Figure 1 and Figure 2 As shown, the mill body 1 includes two groups of symmetrically arranged mill rollers 101, heating elements are installed inside the mill rollers 101, both ends of the mill rollers 101 are rotatably installed on the inner side of the support plate 102, one end of the two groups of mill rollers 101 are respectively connected to the output ends of the two groups of mill motors 103, the mill motors 103 are fixedly installed on the outer side of the support plate 102, the bottom of the support plate 102 is fixedly installed on both sides of the top surface of the frame 104, and a mounting groove 105 is opened in the middle of the top surface of the frame 104, and a storage tray 5 is clamped in the mounting groove 105.

[0032] By setting the internal mixer main body 1, during operation, the output ends of the two groups of internal mixer motors 103 can drive the two groups of internal mixer rolls 101 to rotate towards each other at different speeds, and the surface of the internal mixer rolls 101 can be heated to different temperatures through the heating elements inside the internal mixer rolls 101. The materials stacked above the internal mixer rolls 101 are drawn into the roll gap due to the friction and adhesion on the surface of the internal mixer rolls 101 and the bonding force between the materials. Due to the speed difference between the two groups of internal mixer rolls 101, when the materials enter the roll gap, they will be subjected to a strong shearing action. This shearing action can evenly disperse various components in the materials, change the structure of the materials, increase the interface between components, and achieve distributive mixing. At the same time, as the materials enter the gradually narrowing gap between the internal mixer rolls 101, an extrusion action will occur, and as the transverse pressure increases, the extrusion force will also increase. The materials will deform under this strong extrusion and shearing action. The rubber sheet discharged from the gap between the internal mixer rolls 101 will be wrapped around one of the internal mixer rolls 101 due to the difference in surface speed and temperature between the two internal mixer rolls 101, and then return to the space between the two rolls again. After repeating this process many times, through continuous shearing, extrusion, heating, and mixing, the macromolecular chains inside the rubber are broken, and various components in the formula are evenly blended, ultimately achieving the purpose of rubber mixing.

[0033] In a further preferred embodiment, as Figure 1 and Figure 2 shown, an installation groove 105 is formed in the middle of the top surface of the frame 104, and a storage tray 5 is snap-fitted in the installation groove 105.

[0034] By setting the storage tray 5, the dropped materials can be stored, which is convenient for the operator to add them into the space between the two rolls again, and it is also convenient to remove the storage tray 5 for cleaning after processing.

[0035] Furthermore, as Figure 3 and Figure 4 shown, it further includes multiple groups of material spreading components 2. The material spreading components 2 include a storage tank 201. A discharge pipe 202 is integrally formed at the bottom of the storage tank 201. First discharge ports 203 are formed on both sides of the bottom of the discharge pipe 202. A transmission shaft 204 is arranged inside the storage tank 201. The bottom of the transmission shaft 204 is fixedly connected to the top of a discharge auger 205. The bottom of the discharge auger 205 is rotatably installed at the center of the bottom of the discharge pipe 202. The top of the transmission shaft 204 is rotatably fitted with a top cover 206. The discharge auger 205 is rotatably fitted with the discharge pipe 202. The top cover 206 is fixedly installed on the top of the storage tank 201. A feed port 207 is formed on one side of the top of the top cover 206. A discharge motor 208 is fixedly installed at the center of the top surface of the top cover 206. The output end of the discharge motor 208 is drivingly connected to the top of the transmission shaft 204.

[0036] By setting the discharging motor 208, the output end of the discharging motor 208 can drive the transmission shaft 204 to rotate. The transmission shaft 204 drives the discharging auger 205 to rotate, thereby pushing the compounding agent in the storage tank 201 to move downward and scatter out from the first discharging port 203, replacing the manual addition of the compounding agent by the operator. And through the cooperation of the discharging barrel and the discharging pipe 202, the speed of scattering the compounding agent can be made more uniform, thereby improving the accuracy of adding the compounding agent, reducing the number of times of turning the rubber, improving the processing efficiency, and at the same time reducing the labor intensity of the operator.

[0037] In addition, as Figure 5 shown, a moving sleeve 209 is slidably installed on the outer side of the discharging pipe 202. Second discharging ports 210 are formed on both sides of the bottom of the moving sleeve 209. The other two sides of the top of the moving sleeve 209 are fixedly connected to the telescopic ends of cylinders 211. The cylinders 211 are fixedly installed on the outer walls on both sides of the discharging barrel. Two groups of limiting grooves 212 are symmetrically formed on the surface of the discharging pipe 202. Two groups of limiting blocks 213 are fixedly installed on the inner wall of the moving sleeve 209. The limiting blocks 213 are slidably matched with the limiting grooves 212.

[0038] By setting the moving sleeve 209, the first discharging port 203 can be blocked to prevent the leakage of the compounding agent, and it is also convenient to accurately control the amount of the added compounding agent. And by setting the cylinders 211 and the second discharging ports 210, the telescopic ends of the cylinders 211 can be used to push the moving sleeve 209 to move up and down, so that the first discharging port 203 and the second discharging ports 210 are aligned or staggered, realizing the opening or closing of the discharging pipe 202, thereby facilitating the operator to add the compounding agent.

[0039] It should be noted that, as Figure 1 and Figure 6 shown, it further includes a moving component 3. The moving component 3 includes a transverse lead screw 301. A moving seat 302 is installed on the surface of the transverse lead screw 301. The moving seat 302 is fixedly installed above the interior of the mounting seat 4. One side of the mounting seat 4 is fixedly connected to the storage tank 201. Both ends of the transverse lead screw 301 are rotatably installed on the top of the mounting frame 6. The bottom of the mounting frame 6 is fixedly installed on both sides of the frame 104. A moving motor 303 is fixedly installed on the outer side of the mounting frame 6. The output end of the moving motor 303 is in transmission connection with one end of the transverse lead screw 301. A guide rod 304 is arranged below the transverse lead screw 301. A sliding seat 305 is slidably installed on the surface of the guide rod 304. The sliding seat 305 is fixedly installed below the interior of the mounting seat 4. Both ends of the guide rod 304 are fixedly connected to the mounting frame 6.

[0040] By setting the moving motor 303, the output end of the moving motor 303 can drive the transverse lead screw 301 to rotate, thereby driving the moving seat 302 and the mounting seat 4 to move. The mounting seat 4 drives a plurality of groups of storage tanks 201 on one side to move together, so as to add compounding agents to different positions of the mixed rubber, making the compounding agents sprinkled on the surface of the mixed rubber more uniform, thereby further reducing the number of times of turning the rubber, improving the processing efficiency, and reducing the labor intensity of the operators.

[0041] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
