Description

Technical Field

[0001] The utility model relates to the technical field of tires, in particular to a tread punching device. Background Art

[0002] During the production process, the tire tread needs to be punched to release the gas inside the tread to avoid bulging and other undesirable phenomena caused by bubbles generated by vulcanization.

[0003] In the prior art, a row of vertical needles is typically installed in front of a tread conveyor to perforate the tread. A lifting mechanism is located below the needles, and as the lifting mechanism is driven longitudinally, the needles create puncture holes in the tread. This perforation method results in a low tread conveyance rate, affecting production efficiency, and the needles can easily damage the tread. Utility Model Content

[0004] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a tread punching device that is less likely to cause damage to the tread.

[0005] Based on the above purpose, the present invention adopts the following technical solutions:

[0006] A tread punching device includes: a frame, a pressure roller, a support platform and a punching assembly; the pressure roller is rotatably arranged on the frame and extends in the left and right directions of the punching device; the support platform is at least partially arranged on the lower side of the pressure roller and connected to the frame; the punching assembly is at least partially arranged on the support platform, including a base, a plurality of lifting members arranged on the base and a punching member rotatably arranged on the lifting members; the punching member is a toothed tool.

[0007] Furthermore, the pressure roller is a round roller with a smooth surface.

[0008] Furthermore, the surface of the pressure roller is provided with a plurality of annular grooves corresponding to the punching members.

[0009] The utility model provides a tread punching device, which uses a rolling toothed tool to punch holes in the tread, thereby improving the tread transmission rate and ensuring the reliability of the punching; at the same time, the toothed tool is not likely to cause damage to the tread. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of the punching device provided by the utility model; DETAILED DESCRIPTION

[0011] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0012] At the same time, in order to clearly illustrate the technical solution of this application, the following are also defined: Figure 1 Upper, lower, left, right, front and back sides shown.

[0013] like Figure 1 As shown, this embodiment provides a tread punching device, which includes a frame 11 , a pressure roller 12 , a support platform 13 , and a punching assembly 14 .

[0014] Specifically, the pressure roller 12 is rotatably mounted on the frame 11 and extends in the left-right direction of the punching device. When the tread conveying device conveys the tread, the pressure roller 12 is in close contact with the tread and rotates as the tread is conveyed.

[0015] The support platform 13 is at least partially disposed on the lower side of the pressure roller 12 and connected to the frame 11 for supporting the punching assembly 14 .

[0016] The punching assembly 14 is at least partially mounted on the support platform 13 and includes a base 141, a plurality of lifting members 142 mounted on the base 141, and a punching member 143 rotatably mounted on the lifting members 142. The base 141 is mounted on the support platform 13, and the number and placement of the lifting members 142 and punching members 143 can be adjusted based on the width of the tread, the number of holes to be punched, and the locations of the holes. When punching the tread, all lifting members 142 operate, raising the punching member 143 toward the tread until the punching member 143 at least partially penetrates the tread. The punching member 143 can rotate around the top of the lifting member 142 as the tread is conveyed, continuously punching holes in the tread. The lifting member 142 is a pressure cylinder, and the punching member 143 is a toothed cutter.

[0017] Through the above arrangement, the reliability of the punching of the punching member 143 can be guaranteed while improving the tread transmission rate; at the same time, the punching member 143 is a toothed tool, which is not easy to cause damage to the tread, thereby improving the output quality of the tread.

[0018] More specifically, the pressure roller 12 is a round roller with a smooth surface, so that when punching, the lifting member 142 can lift the punching member 143 to abut against the pressure roller 12, preventing the punching member 143 from excessively piercing the tread, further reducing the possibility of damage to the tread.

[0019] It is understandable that the pressure roller 12 may also be provided with a plurality of annular grooves on its surface corresponding to the punching members 143 , so as to cooperate with the punching members 143 to punch holes in the tread more conveniently.

[0020] The above is a description of the embodiments of the present invention. Through the above description of the disclosed embodiments, professional and technical personnel in the field can implement or use the present invention. Various modifications to these embodiments will be obvious to professional and technical personnel in the field. The general principles defined in this article can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but should conform to the widest scope consistent with the principles and novel features disclosed herein.
