Description

Technical Field

[0001] The utility model relates to the technical field of tire production, and more specifically, to a rubber tire trimming device. Background Art

[0002] After the tire is produced, burrs will be generated on the inner ring, so the burrs need to be removed. In the traditional manufacturing process, the burrs on the inner ring of the tire are generally removed manually using an electric grinder. Since the tire cannot rotate, the operator needs to move it in a circular direction, which not only wastes manpower, but also affects production efficiency.

[0003] In order to solve the above problems, a Chinese patent (publication number: CN210336617U) discloses a rubber tire trimming device, which includes a frame, a turntable, a shaft driving mechanism, a slide, a left clamping arm, a right clamping arm and a slider driving mechanism.

[0004] Although the above technical solution limits the position of the tire by setting the left and right clamp arms, and then the worker can stand in a fixed position to grind and remove the burrs on the inner ring of the tire with an electric grinder, thereby improving production efficiency, the inventor found in the process of implementing the above technical solution that after the tire is fixed by the left and right clamp arms, the inner ring of the tire needs to be grinded by a manual handheld electric grinder, which tests the grinding skills and experience of the workers, and the quality is not stable enough. Moreover, after grinding one side of the tire, it needs to be turned over, and the left and right clamp arms need to be readjusted, which is time-consuming and laborious. Utility Model Content

[0005] The utility model aims to provide a rubber tire trimming device, which solves the problems in the prior art of requiring manual grinding and changing the tire edge, resulting in unstable grinding quality and time-consuming and labor-intensive.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a rubber tire trimming device, including a workbench, a top of which is vertically rotatably connected to a working rod through a bearing; two mounting plates, which are symmetrically mounted on the top of the workbench; a driving assembly, which is arranged inside the workbench, and the driving assembly is used to drive the working rod to rotate longitudinally; a limiting assembly, which is arranged at the top of the working rod, and the limiting assembly is used to limit and fix the tire; there are two groups of trimming assemblies, which are respectively arranged on two mounting plates, and the two groups of trimming assemblies are respectively used to trim both sides of the tire.

[0007] The working principle of this technical solution is as follows: when in use, first place the tire that needs to be trimmed on the top of the working rod and fix it with a limit assembly, then adjust the trimming assemblies on the two mounting plates so that they are located on the upper and lower sides of the inner ring of the tire, respectively, and finally start the driving assembly to drive the working rod to rotate. The two sets of trimming assemblies can trim the inner ring of the tire at the same time, and the tire can be removed after completion.
