Description

Technical Field

[0001] This utility model relates to the field of automotive processing equipment technology, and in particular to a positioning device for tire cutting. Background Technology

[0002] Currently, with social progress and economic development, various vehicles have become indispensable consumables for people's lives and work. Tires are essential vehicle parts, and their mass production and application lead to a waste of rubber raw materials. The current practice is to recycle tires to avoid this waste. The processing of waste tires generally includes the following steps: breaking the tire into small pieces, grinding these pieces, and then sorting and recycling them. The final recycled products mainly include rubber, steel wires embedded in the rubber, and fibers. Therefore, how to break down the entire tire into smaller pieces for subsequent recycling has become the primary problem to be solved in tire recycling.

[0003] CN 111283905 A discloses a tire cutting device, including a fixed frame, a circular cutter head drive mechanism, and a first and a second circular cutter head pivotally connected to the fixed frame. The blades of the first and second circular cutter heads intersect and fit together. The circular cutter head drive mechanism drives the first and second circular cutter heads to rotate, so that the first and second circular cutter heads cooperate to bite and cut the tire that enters between their blades. Through the cooperation of the circular cutter head drive mechanism and the first and second circular cutter heads, after the tire is fed between the blades of the first and second circular cutter heads, the first and second circular cutter heads, driven by the circular cutter head drive mechanism, cooperate to bite and cut the tire, completing the tire cutting operation. This facilitates subsequent cutting of the tire into smaller pieces, thereby achieving tire recycling.

[0004] When the tire is cut into strips using the above-mentioned tire cutting device, the tire will rotate under the action of the circular cutter disc. Due to the large size of the car tire, it is not convenient to position the tire, causing the tire to move around randomly during the cutting process. Furthermore, when cutting tires of different sizes, it is not convenient to accurately adjust the feed position, thus affecting the cutting effect. Utility Model Content

[0005] In order to overcome the above-mentioned defects in the prior art, the present invention provides a positioning device for tire cutting.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a positioning device for tire cutting, including a cutting device, a worktable provided on the front side of the cutting device, an mounting plate movably mounted on the worktable, a cylinder provided on the worktable for driving the mounting plate to move, a support seat movably mounted on the top of the mounting plate, a screw adjustment mechanism provided on the mounting plate for adjusting the position of the support seat, a connecting plate rotatably mounted on the top of the support seat, a positioning seat detachably mounted on the connecting plate, a mounting frame provided on the side of the positioning seat near the cutting device, and a laser wire punch fixedly mounted on the mounting frame.

[0007] Furthermore, the bottom end of the positioning seat is provided with a flange connection part, and several sets of connecting bolts are installed near the edge of the connecting plate. The positioning seat is fixedly installed on the connecting plate by the connecting bolts. The top end of the positioning seat is provided with a mounting part, which is a cylindrical structure. A truncated cone is provided at the connection between the mounting part and the flange connection part.

[0008] Furthermore, the screw adjustment mechanism includes an adjustment screw, which is rotatably mounted on the top of the mounting plate. The axis of the adjustment screw is parallel to the axis of the cutter head of the cutting device. A handwheel is fixedly mounted on the front end of the adjustment screw. A connecting nut is fitted onto the adjustment screw. The connecting nut is fixedly mounted on the bottom of the support base. Slider blocks are fixedly mounted on the left and right ends of the bottom of the support base. Slide rails are slidably mounted on the sliders. The slide rails are fixedly mounted on the top of the mounting plate.

[0009] Furthermore, the mounting bracket has a C-shaped structure and is fixedly installed on the rear side of the workbench. The laser wire cutter is fixedly installed on the top of the mounting bracket and is flush with the cutting disc of the cutting device.

[0010] Furthermore, guide rods are fixedly installed at both ends of the worktable, and guide seats are slidably installed on the guide rods. The guide seats are fixedly installed at the bottom of the mounting plate. The cylinder is fixedly installed at the end of the worktable away from the cutting device. A push plate is fixedly installed on the power output shaft of the cylinder, and the push plate is fixedly connected to the mounting plate.

[0011] The beneficial effects of this utility model are that the design of this utility model fixes the tire onto the positioning seat to prevent the tire from moving around during the cutting process. By changing the positioning seat of different specifications, it can be adapted to tires of different sizes. When adjusting the position of the tire, the laser line emitted by the laser wire cutter shines on the top surface of the tire. Through the laser line, the operator can clearly understand the cutting position and can adjust the front and rear position of the bearing seat through the screw adjustment mechanism, thereby accurately adjusting the cutting position and ensuring the cutting effect.
