Description

Technical Field

[0001] The utility model belongs to the technical field of tire recycling, and in particular relates to an automatic waste tire cutting device. Background Art

[0002] Tires are components used in vehicles and machinery that facilitate the movement of vehicles and machinery by rolling. Tires also play a role in cushioning and supporting. Tires are mostly made of rubber products. Since tires bear the entire gravity of the vehicle or machinery, they are subjected to various negative impacts during the vehicle or machinery process, making them more susceptible to damage. As a result, a large number of waste tires are generated. Waste tires can be recycled to reduce losses. When recycling waste tires, they need to be cut, and a cutting device is usually used to cut the tires.

[0003] Chinese patent CN111037799B proposes a tire recycling and cutting device, including a support, a roller, etc.; a rotating roller is embedded in one side of the support. The cutter rotates to cut the waste tire, and the position of the cutter can be adjusted to cut waste tires of different diameters and thicknesses. When the cutter moves downward to puncture the waste tire, the second swing rod presses the waste tire, so that during the puncture and cutting of the waste tire, the waste tire can be fixed to prevent sliding, so as to better complete the cutting, and by swinging the first swing rod upward, the waste tire that has been cut can be pushed away without manual operation.

[0004] However, in the above patent, the tire is fixed only by the card slot and the pressing plate when cutting the tire. Since the tire is an elastic hollow object, the fixation of the tire is relatively unstable. Since the above patent presses and fixes the tire from the outside, the pressing plate will flip the cutting plate to cut the tire, resulting in incomplete cutting.

[0005] Based on this, the utility model designs an automatic waste tire cutting device to solve the above problems. Utility Model Content

[0021] The utility model has the following technical effects:

[0022] When the tire needs to be fixed, the cylinder is started, and the cylinder drives the pressing plate to move downward under the support of the L-shaped support plate through the push rod under the limit guide of the limit sleeve and the limit slide rod, and the pressing plate drives the upper ends of the upper and lower wall cutting assemblies to move downward, and the upper ends of the upper and lower wall cutting assemblies drive the slide plate and the limit rotating shaft to move downward, and the limit rotating shaft and the slide plate drive the extrusion plate to move downward into the inner side of the tire through the linkage rod. When the limit rotating shaft moves downward to be clamped with the upper end of the linkage cutting assembly, the upper ends of the upper and lower wall cutting assemblies drive the slide plate to move downward under the limit of the limit rotating shaft, and the slide plate drives the end of the linkage rod connected thereto close to the limit rotating shaft to move downward. The lower end of the moving rod cannot move up and down, so that the end of the linkage rod away from the limiting rotating shaft drives the extrusion plate to move in the direction away from the limiting rotating shaft, and when the extrusion plate contacts the inner end of the tire, the cylinder continues to operate, so that the extrusion plate squeezes the tire from the inside of the tire to the outside, thereby completing the horizontal fixation of the tire. Since it is done from the inner end of the tire, it does not affect the cutting of the outside of the tire, and the upper and lower wall cutting assemblies are driven by the pressing plate to squeeze the tire in the upper and lower directions, thereby achieving the vertical fixation of the tire, thereby completing the fixation of the tire, so that only one set of cylinders is needed to achieve the fixation of the tire without affecting the cutting of the tire, and no multiple sets of driving parts are required, saving costs.

[0023] When the tire is fixed by the tire fixing assembly after being pressed, the first motor is started, and the output end of the first motor drives the linkage rotating rod to rotate, and the linkage rotating rod drives the movable spur gear to rotate, and the movable spur gear drives the cutting blade string to rotate. At this time, the second motor is started, and the second motor drives the threaded rod to rotate, and the threaded rod drives the slide block to move in the direction close to the tire under the limiting guide of the slide groove. Since the movable spur gear and the cutting blade string are both connected to the slide block and the movable spur gear is limitedly slidably connected with the linkage rotating rod, the linkage rotating rod drives the cutting blade string to rotate through the movable spur gear, and at the same time, the threaded rod can drive the cutting blade string to move in the direction close to the tire through the slide block, thereby realizing that the cutting blade string approaches the tire and cuts the tire while rotating, without the need for an additional driving assembly, thereby saving costs. In addition, when the pressing plate moves downward, the pressing plate drives the upper extrusion plate to move downward through the first linkage sliding rod and the first spring, and the upper extrusion plate The pressing plate moves downward to squeeze the tire, and the tire squeezes the lower squeezing plate downward. At this time, the lower squeezing plate drives the second linkage sliding bar to move downward, and the second linkage sliding bar drives the second spring to stretch and deform the second spring, and the upper squeezing plate drives the first linkage sliding bar to move upward relative to the pressing plate. At this time, the first linkage sliding bar drives the first spring to stretch and deform the first spring. At this time, the two sets of cutting blades pass through the upper and lower squeezing plates and the upper and lower side walls of the tire respectively. When the limiting shaft moves to the bottom and is engaged with the output end of the first motor, the first motor drives the linkage rod and the squeezing plate to rotate through the limiting shaft and the slide plate. Since the squeezing plate squeezes the tire at this time, the squeezing plate drives the tire to rotate. Since the slide plate and the upper squeezing plate are rotationally connected, the two sets of cutting blades cut the upper and lower side walls of the tire respectively while the tire rotates, thereby realizing the cutting of the inside of the tire. The cutting of the inside of the tire can be achieved without using other cutting machines. BRIEF DESCRIPTION OF THE DRAWINGS

When the limit rotating shaft 221 moves downward to engage with the upper end of the linkage cutting component 3, the upper end of the upper and lower wall cutting components 4 drives the slide plate 222 to move downward under the limit of the limit rotating shaft 221, and the slide plate 222 drives the linkage rod 223 connected thereto to move downward near the end of the limit rotating shaft 221. Since the lower end of the linkage rod 223 connected to the limiting shaft 221 cannot move up and down, the end of the linkage rod 223 away from the limiting shaft 221 drives the squeezing plate 224 to move in the direction away from the limiting shaft 221, and when the squeezing plate 224 contacts the inner end of the tire, the cylinder 212 continues to operate, so that the squeezing plate 224 squeezes the tire from the inside of the tire to the outside, thereby completing the horizontal fixation of the tire.
