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] like Figure 1 to Figure 2 As shown, the tire retreading and cutting machine of the present invention includes a cylinder 1 and a support rod 2, a trapezoidal groove 3 is provided on the support rod 2, a protrusion 4 is installed on the output end of the cylinder 1, and the protrusion 4 and the trapezoidal Groove 3 cooperates, and one end of described support rod 2 is provided with tool support 5, and cutter 6 is rotatably arranged on tool support 5, and motor 7 is arranged in cutter 6 support, and the end of cutter 6 is all connected with the output end of motor 7 There are bevel gears 8, and two bevel gears 8 mesh with each other, and a balance weight 10 is also installed on the other end of the support rod 2. When the present invention works, the cylinder 1 is installed on the clamping equipment of the tire, and according to the size of tires of different types, the cylinder 1 is adjusted so that the support rod 2 moves up and down, and the cutter 6 is rotated and ar...

Embodiment 2

[0024] like figure 2 As shown, in this embodiment, on the basis of 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 to the tool holder 5, and the other end of the rotating shaft 9 is connected to the bevel gear 8; a plurality of arc-shaped blades 11 are evenly arranged on the rotating shaft 9, and the arc-shaped blades 11 are hinged with the rotating shaft 9, and on the cylinder 13 There is an opening corresponding to the arc-shaped blade 11, and the arc-shaped blade 11 runs through the opening. A block 14 is arranged on the inner wall of the cylinder 13. One side of the block 14 is an arc-shaped concave surface, and the arc-shaped concave surface and the arc-shaped blade 11 The outer sides of the arcs are connected by springs 12. The rotating shaft 9 can ro...

Embodiment 3

[0026] like figure 1 As shown, in this embodiment, on the basis of Embodiment 1, a baffle plate 15 is obliquely arranged on the support of the cutter 6, and the inclination direction of the baffle plate 15 is consistent with the bending direction of the arc-shaped blade 11; the baffle plate 15 The angle of inclination is 35o~55o. When the arc blade 11 is grinding the tread, a large amount of debris and dust will be produced, and the oblique shielding plate 15 can prevent the debris generated by the arc blade 11 from splashing around, and the inclined direction of the shielding plate 15 is consistent with the arc shape. The bending direction of the blade 11 is consistent, which can minimize debris and dust splashing in the operating environment and ensure a clean operating environment; the inclination angle of the shielding plate 15 is set within the range of 35o~55o, which can prevent debris When the blade 11 splashes out, it rebounds on the shielding plate 15 to avoid second...

Abstract

The invention discloses a tyre retreading cutting machine, comprising a cylinder and a support rod, wherein a trapezoid groove is formed in the support rod; a bump is arranged on the output end of the cylinder and matched with the trapezoid groove; a tool bracket is arranged at one end of the support rod; a tool is rotationally arranged on the tool bracket; a motor is arranged inside the tool bracket; the end part of the tool and the output end of the motor are connected with conical gears; the two conical gears are meshed with each another; a balance block is also arranged at the other end of the support rod; the bump on the output end of the cylinder is matched with the trapezoid groove in the support rod when the tool goes up and down; the tool can move in the horizontal direction, so that the contact area of the tool and a tread is timely adjusted, and thus local excessive polishing on the tread is avoided.

Description

technical field [0001] The invention relates to a grinding tool, in particular to a tire retreading cutting machine. Background technique [0002] Tire retreading is a positive way to recycle waste tires, and it is the extension and processing and reuse of the tire industry. It is of great significance to promote resource conservation and comprehensive utilization, and promote the transformation of economic growth mode and sustainable development. As far as its prospects are concerned, the retreading of waste tires is an indispensable industry in the automobile industry and transportation just like the tire industry. [0003] Tire retreading refers to a process in which old tires are partially repaired and reapplied with rich tread rubber, and then vulcanized to restore their use value. Tire retreading and utilization refers to the reuse of old tires with repair value after retreading and repairing. After processing and crushing waste tires that cannot be retreaded into var...
