Problems solved by technology

After the small loader has been used for a long time on complex and rough terrain, the tread pattern will be worn out, and the adhesion between the tire and the road surface will be reduced, which will affect the traction and passing performance of the loader and increase fuel consumption. The impact performance is reduced, which weakens the protective effect of the tire tread on the carcass, and easily causes the puncture and explosion of the tire cord layer. Therefore, when the tread wears to a certain limit, the tire should be retreaded in time; ordinary tire grinding on the market When the equipment is grinding, the retreaded tire tread often has inconsistent dimensions, and the tread unevenness that deviates from the balanced shape appears on the cross-sectional structure, which makes it difficult to remove the tire from the grinding equipment after grinding

Embodiment 1

[0022] Such as Figure 1 to Figure 2 As shown in the tire retreading and cutting machine of the present invention and its use method, the cylinder 1 is installed on the tire clamping device. According to the size of different types of tires, the cylinder 1 is adjusted so that the support rod 2 can move up and down, and the cutter 6 is rotated and arranged on the cutter bracket 5, and then achieve the purpose of adjusting the cutter 6 to the best processing position. The motor 7 rotates to drive the two bevel gears 8 to mesh with each other. The cutter 6 starts to rotate to start the grinding process, which improves the working efficiency of the tire during grinding and reduces the tire When the tool 6 is raised and lowered, the protrusion 4 installed on the output end of the cylinder 1 engages with the trapezoidal groove 3 on the support rod 2, which can move the tool 6 in the horizontal direction, which is convenient for the tool 6 and The tire surface contact area is adjusted...

Embodiment 2

[0024] Such as figure 2 As shown, this embodiment is based on embodiment 1. The cutter 6 includes a cylinder 13 and a rotating shaft 9. The rotating shaft 9 is arranged in the cylinder 13, and the two ends of the rotating shaft 9 protrude from the two ends of the cylinder 13. One end of the rotating shaft 9 is rotatably connected with the tool holder 5, and the other end of the rotating shaft 9 is connected with the bevel gear 8; the rotating shaft 9 is evenly provided with a plurality of arc blades 11, the arc blades 11 are hinged with the rotating shaft 9, and the cylinder 13 is An opening corresponding to the arc-shaped blade 11 is opened, the arc-shaped blade 11 penetrates the opening, a stop 14 is provided on the inner wall of the cylinder 13, and one side of the stop 14 is an arc-shaped concave surface. The arc-shaped concave surface and the arc-shaped blade 11 The outer sides of the arc are connected by a spring 12. The rotating shaft 9 can rotate freely on the support ...

Embodiment 3

[0026] Such as figure 1 As shown, this embodiment is based on the first embodiment. A shielding plate 15 is obliquely provided on the holder of the cutter 6, and the inclination direction of the shielding plate 15 is consistent with the bending direction of the arc blade 11; The angle of inclination is 35o~55o. When the curved blade 11 is grinding the tread, a large amount of debris and dust will be generated. The obliquely arranged shielding plate 15 can prevent the debris generated by the curved blade 11 from splashing around, and the oblique direction of the shielding plate 15 is the same as the arc shape. The bending direction of the blade 11 is consistent, which can minimize the debris and dust splash in the operating environment, and ensure the cleanliness of the operating environment; the inclination angle of the shield plate 15 is set in the range of 35o to 55o to prevent debris from following the arc When the blade 11 splashes out, it rebounds on the shield plate 15 to...

Abstract

The invention discloses a tyre retreading cutting machine and a use method thereof. When a cutter is lifted, a bulge installed on the output end of an air cylinder is matched with a trapezoidal groove in a support rod, and the cutter can move in the horizontal direction, so as to facilitate the timely adjustment of the contact area between the cutter and the tyre surface and avoid local excessive polishing to the tyre surface.

Description

Technical field [0001] The invention relates to a grinding tool, in particular to a tire retreading cutting machine and a method of use thereof. Background technique [0002] Tyre retreading is an active way for the recycling of waste tires. It is an extension and processing and reuse of the tire industry. It is of positive significance for promoting resource conservation and comprehensive utilization, promoting the transformation of economic growth mode and sustainable development. As far as its prospects are concerned, the retreading of used tires, like the tire industry, is an indispensable industry in the automotive industry. [0003] Tire retreading refers to a process in which old tires are partially repaired and re-applied with rich tread rubber, and then vulcanized to restore their use value. Tire retreading and utilization refers to the retreading and re-use of old tires with repair value. The waste tires that cannot be retreaded are processed and broken into various rub...
