Description

Technical Field

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

[0002] A solid tire is a tire made of rubber material. Unlike a pneumatic tire, there is no air-filled space inside the solid tire, and the entire tire is made of strong solid material.

[0003] In the process of manufacturing solid tires, removing the burrs on the outer ring surface is an important step. Burrs refer to the excess part of the outer edge of the solid tire. It is an irregular edge formed during the solid tire molding process. Burrs not only affect the contact between the solid tire and the ground, but also affect the appearance. Therefore, the burrs on the outer ring surface of the solid tire need to be removed.

[0004] The tire trimming machine is a device that is specially designed to remove the burrs on the outer ring surface of the tire. During the burr removal process, the solid tire is placed in a mold with an annular groove that matches the shape of the solid tire. The mold is then driven to rotate by a driving mechanism, and the upper end surface of the solid tire is pressed by the pressure wheel of the pressure wheel assembly to stabilize the solid tire. As the mold rotates, the solid tire rotates, and the pressure wheel of the pressure wheel assembly rolls. At this time, the blade is driven by the electric push rod to move to the outer ring surface of the solid tire, and the burrs are removed by the static blade.

[0005] However, the requirements for mold specifications for burr removal of solid tires with different inner diameters will also change accordingly. At this time, the staff needs to remove the original mold and install a mold of corresponding specifications, which is cumbersome. At the same time, the burr removal of each solid tire requires the use of a pressure wheel assembly to press the upper end surface of the solid tire and then release the solid tire to remove it, which is not efficient enough. To this end, we propose a solid tire processing device. Utility Model Content

[0024] See also Figure 1 In the figure, the cutting mechanism includes an L-shaped frame 2, which is fixedly connected to the lower edge of the outer wall of the base 9, and an electric push rod 3 is fixedly installed on the upper edge of the vertical wall of the L-shaped frame 2, and a blade 4 is fixedly connected to the telescopic shaft end of the electric push rod 3, and the blade 4 is close to the outer ring surface of the tire body 6.

[0025] See also Figure 1-Figure 3 In the figure, the bottom end of the stud 8 is fixedly connected with a rotating block 1; by setting the rotating block 1, it is convenient to rotate the stud 8.

[0026] Working principle: When trimming the solid tire body 6, first, place the tire body 6 on the upper end of the cylindrical shell 11, and multiple positioning columns 5 are located on the inner side of the tire body 6, then rotate the stud 8, the stud 8 can drive the connecting ring 18 connected to its outer wall thread to move upward, the connecting ring 18 can drive multiple connecting rods 13 to rotate synchronously, and the top ends of the multiple connecting rods 13 will move away from the center of the cylindrical shell 11, and the multiple connecting rods 13 can drive the sliders 15 connected to the top ends of the respective rotating sliders to rotate in the cylindrical shell. The plurality of sliders 15 can drive the blocks 16 on the outer wall thereof to slide in the corresponding slots 14 in the slots 7, and the plurality of sliders 15 can drive the positioning posts 5 connected to their respective top ends to slide at the upper end of the cylindrical shell 11 away from the center of the cylindrical shell 11 until the plurality of positioning posts 5 are tightly attached to the inner ring surface of the tire body 6. Then, the tire body 6 will be fixed, and the tire body 6 is applicable to tire bodies 6 of different inner diameters. In the process, there is no need to replace the structure for positioning the tire body 6, and the operation is simple.

[0027] Then, the motor 10 is connected to an external power source, so that the motor 10 can drive the cylindrical shell 11 to rotate, and the tire body 6 rotates accordingly. Then, the electric push rod 3 is connected to the external power source, so that the electric push rod 3 can drive the blade 4 to fit the burr of the outer wall of the tire body 6. As the tire body 6 continues to rotate, the burr on the outer ring surface of the tire body 6 will be continuously cut off.

[0028] It should be noted that when the positioning column 5 is in close contact with the inner ring surface of the tire body 6, since the tire body 6 is a rubber product with a certain elasticity, under the extrusion pressure applied by the positioning column 5 to the inner ring surface of the tire body 6, the inner walls of the multiple annular grooves 17 on the outer wall of the positioning column 5 will also be in close contact with the inner ring surface of the tire body 6. The annular grooves 17 form a barrier to the upward movement of the tire body 6. Therefore, the tire body 6 is not easy to move upward during the trimming process and will be stabilized. There is no need to use an additional mechanism to press down and stabilize the tire body 6, thereby improving work efficiency.
