Abstract
Description
Technical Field
[0001] The invention relates to the technical field of tire rubber processing, and in particular to a quick-changing device for apex rubber pressing rollers. Background Art
[0002] The tire apex is a vital component of the tire structure. It is located between the tire sidewall and the tread block, forming a distinct triangular area. This specially designed rubber compound not only enhances the lateral rigidity of the tire, but also improves the handling stability and grip of the tire when turning. The tire apex is made of high-quality rubber material, which is precisely processed and vulcanized to ensure that it has excellent wear resistance, tear resistance and elasticity. During the driving process of the tire, the apex can effectively disperse and absorb the impact force from the road, protect the internal structure of the tire from damage, and extend the service life of the tire. According to the tire bead forming process, the apex rubber strip is firstly fitted to the steel ring, and the rubber ring application area is rolled and sealed. Then the completed bead is removed, and the new steel ring is re-clamped, and the next forming cycle is carried out. At present, all process actions are completed in series. In the actual production process, the operator will replace the rubber strips of different widths according to the needs of the tire factory for production. The rollers used for the rubber strips of different widths have different shapes. Therefore, the roller device for rolling and sealing the rubber ring application area needs to be replaced in real time. If the rubber strips of different widths are frequently replaced, the conventional structure will accumulate a long time in replacing the roller device, affecting production efficiency.
[0003] Therefore, it is necessary to redesign the pressing roller device to effectively prevent the problems existing in the above-mentioned background technology. Summary of the invention
[0004] The object of the present invention is to provide a quick-change device for apex rubber pressing rollers to solve the problems mentioned in the above background technology.
[0005] To achieve the above object, the present invention provides the following technical solutions: A apex rubber pressing roller quick-change device comprises: a roller quick-change component 1, a roller quick-change component 2 is arranged on the left side of the roller quick-change component 1, a roller quick-change component 3 is arranged on the left side of the roller quick-change component 2, and a roller quick-change component 4 is arranged on the left side of the roller quick-change component 3. The internal structures of the roller quick-change components 1, 2, 3 and 4 are the same. A T-slot connector is arranged on the top of the roller quick-change component 1, a knob plunger is arranged on the front side of the T-slot connector, and a locking handle is arranged on the right side of the knob plunger.
[0006] Through the above technical scheme, through the setting of multiple pressure roller quick-change assemblies, it is convenient to quickly replace different pressure roller plates for the apex rubber pressure roller, so as to achieve efficient and fast pressure roller for the apex rubber, improve the efficiency of apex rubber processing and production, and facilitate user use.
[0007] Preferably, the pressure roller quick-change assembly 1 includes a pressure roller body assembly, a quick-change connecting plate is arranged on the top of the pressure roller body assembly, the right side of the quick-change connecting plate is fixedly connected to the pressure roller plate 1 by bolts, the left side of the quick-change connecting plate is fixedly connected to the pressure roller plate 2 by bolts, and the pressure roller body assembly is movably mounted on the inner sides of the pressure roller plate 1 and the pressure roller plate 2 by bolts.
[0008] Through the above technical solution, through the design of quick-change connecting plate and bolt connection, the roller body assembly can be quickly disassembled and installed from roller plate one and roller plate two, which greatly improves the efficiency and convenience of replacing rollers. This is particularly important for production lines that need to frequently replace rollers, which can significantly reduce downtime and production costs. Easy maintenance: The quick-change design makes the maintenance of the roller body assembly easier. When the roller body assembly is worn or fails, the staff can quickly disassemble and replace or repair it without dismantling the entire equipment, thereby reducing the difficulty and cost of maintenance. Strong flexibility: Since the roller body assembly can be easily replaced, rollers of different specifications and materials can be quickly adjusted or replaced according to different production needs to adapt to different production processes and product requirements. This flexibility helps to improve the adaptability and competitiveness of the production line. Stable structure: The roller body assembly is fixed between roller plate one and roller plate two by bolts, ensuring the structural stability and working reliability of the entire assembly. This design can prevent the roller from loosening or falling off during operation, thereby ensuring the safety and production efficiency of the production line.
[0009] Preferably, the pressure roller body assembly includes a large pressure roller body, a spacer ring is arranged inside the large pressure roller body, retaining rings are fixedly installed on both sides of the large pressure roller body, a large pressure roller shaft is arranged inside the spacer ring, and a deep groove ball bearing is fixedly installed on the surface of the inner wall of the large pressure roller body.
[0010] Through the above technical scheme, the setting of the spacer and the retaining ring helps to fix the position of the large pressure roller body to prevent it from shifting or shaking during operation, thereby improving the structural stability of the entire assembly. As a type of rolling bearing, the deep groove ball bearing can withstand a large radial load and a certain axial load, which increases the durability and service life of the large pressure roller body. Efficient transmission: The large pressure roller shaft is connected to the large pressure roller body through a deep groove ball bearing. This connection method can reduce friction and wear, making the transmission more efficient and smooth. Stable transmission helps to maintain the stability and consistency of the pressure roller body assembly during operation, thereby improving production efficiency. Strong adaptability: The design of this pressure roller body assembly has certain versatility and flexibility, and can adapt to different working environments and process requirements. By adjusting the parameters of components such as spacers, retaining rings and deep groove ball bearings, the performance of the pressure roller body assembly can be fine-tuned to meet specific production needs.
[0011] Compared with the prior art, the present invention has at least the following beneficial technical effects: 1. The T-slot structure greatly simplifies the operation of disassembling and installing bolts to replace the roller body in the past, and shortens the time to replace the roller body from five minutes to less than one minute. The width of the apex rubber is frequently changed during the production process of the tire factory. After adopting the roller quick-change device, more than one hour of time is saved in the 24-hour production process, which greatly improves the production efficiency affected by the long time of replacing the tooling.
[0012] 2. The pressure roller quick-change assembly cooperates with the T-slot connector and is limited by the baffle. It is positioned by the knob plunger. The pressure roller quick-change assembly can be fixed only by the handle, which reduces the replacement time, facilitates operation, and has reliable positioning. BRIEF DESCRIPTION OF THE DRAWINGS
