Description

Technical Field

[0001] The utility model relates to the technical field of rubber rollers, in particular to a wear-resistant rubber roller for tire molding. Background Art

[0002] In the tire forming process, the rubber roller mainly plays the role of transferring pressure, heat, and materials. Through the rotation of the rubber roller, rubber, fiber and other materials can be evenly compacted and mixed to form the tread and carcass of the tire. When producing rubber rollers, the rubber sleeve is often adhered to the roller core of the rubber roller to form the rubber roller. However, the installation of the rubber sleeve by adhesion not only makes it easy for the rubber sleeve to separate from the roller core, but also when the rubber sleeve is worn, it is impossible to replace the rubber sleeve alone, which affects the normal use of the rubber roller and increases the cost of using the rubber roller. Therefore, we propose a wear-resistant rubber roller for tire forming to solve the above problems. Utility Model Content

[0009] Preferably, fixing frames are fixedly installed at both ends of the inner part of the groove, and positioning plates are fixedly installed at the outer side of the rod body of the connecting rod, and the positioning plates are snap-fitted between the fixing frames. An auxiliary groove is provided inside the positioning plate, and a push plate is movably installed inside the auxiliary groove. Limiting rods are fixedly installed at both ends of the push plate close to the hexagonal groove, and the limiting rods are movably installed inside the auxiliary groove, and the limiting rods are snap-fitted to the fixing frames.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] (1) In the utility model, the wear resistance of the rubber sleeve is increased by the hardened layer, and the service life of the rubber sleeve is extended. Then, the rubber sleeve and the roller core are formed into a whole by the cooperation of the first mounting rod, the second mounting rod and the mounting hole, so as to replace the adhesive method for mounting the rubber sleeve and the roller core, so as to avoid the separation and slipping between the rubber sleeve and the roller core, and make it easier for the roller core to drive the rubber sleeve to process the tire.

[0013] (2) In the utility model, the rubber sleeve and the roller core are installed by the cooperation of the first installation rod and the second installation rod. Then, when the rubber sleeve needs to be replaced, it is only necessary to open the movable plate and then remove and replace the rubber sleeve alone.

[0028] The hardened layer is formed on the surface of the rubber roller by chemical reaction, such as chemical nickel plating, chemical chromium plating, etc., to form a coating with high hardness and good wear resistance on the surface of the rubber sleeve 1, thereby improving the overall wear resistance of the rubber roller.

[0029] The working principle of this wear-resistant tire forming rubber roller:

[0030] When in use, first, when the user needs to install the rubber sleeve 1, he only needs to install the rubber sleeve 1 on the outside of the roller core 2, and at the same time, the first installation rod 303 is inserted into the inside of the installation hole 101, so that the rubber sleeve 1 and the fixed plate 301 fit together to achieve the initial installation work, and then the user inserts the second installation rod 304 into the inside of the installation hole 101, and then with the push of the movable plate 302, the second installation rod 304 will be stuck in the inside of the limiting hole 305, so that the fixed plate 301, the first installation rod 303, the rubber sleeve 1, The second mounting rod 304 and the movable plate 302 are initially formed as a whole, and then the user inserts the hexagonal wrench into the hexagonal groove 321. At the same time, as the hexagonal wrench is inserted, the push rod 320 is pushed, and the push rod 320 pushes the push plate 318, so that the push plate 318 drives the limit rod 322 to enter the auxiliary groove 317. At the same time, the push plate 318 also squeezes the spring 319. After the hexagonal wrench is inserted, the user can The connecting rod 314 and the rotating rod 307 are controlled to rotate, so that the connecting rod 314 drives the positioning plate 316 to be inserted into the fixed frame 315, and the rotating rod 307 also pushes the guide frame 311 through the elliptical guide groove 312, and finally the guide frame 311 pushes the positioning rod 308 out of the temporary storage groove 309 and inserts it into the interior of the positioning hole 310, so as to realize the installation of the first mounting rod 303 and the second mounting rod 304, so that the fixed plate 301, the movable plate 302, the first mounting rod 303 and the second mounting rod 304 are installed. 04 forms a whole, and connects the rubber sleeve 1 and the roller core 2 more stably. Then, after the positioning rod 308 is installed, the user can take out the hexagonal wrench, and then the spring 319 will push the push plate 318 to reset, so that the push plate 318 drives the limit rod 322 to insert into the interior of the fixing frame 315, so as to realize the positioning of the connecting rod 314 and the rotating rod 307, and at the same time, the push plate 318 also pushes the push rod 320 back to the interior of the hexagonal groove 321, waiting for the next time to push the push plate 318 with the hexagonal wrench.
