Detailed Implementation

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0023] Reference Figs. 1-3 A rubber tire cutting device includes a fixed frame 2. Two slide rails 20 are bolted to the inner wall of one side of the fixed frame 2, and the slide rails 20 are slidably connected to an L-shaped frame 4. The cooperation of the two slide rails 20 makes the sliding process of the L-shaped frame 4 on the inner wall of the support frame 1 more stable and prevents deviation. The L-shaped frame 4 is slidably connected to the inner wall of one side of the fixed frame 2. The top of the L-shaped frame 4 has an inclined surface 5. A stop block 6 is welded to the top of the L-shaped frame 4. A fixed plate 11 is welded to the top of the fixed frame 2. A connecting shaft 13 is rotatably connected to one side of the fixed plate 11 through a bearing. A take-up roller 12 is connected to the outer circumference of both ends of the connecting shaft 13 through a key. A pull rope 19 with one end fixed to the take-up roller 12 is wound around the outer circumference of the take-up roller 12, and the other end of the pull rope 19 passes through the fixed frame 2 and is fixed to the stop block 6. A belt is provided on one side of the fixed plate 11. The power mechanism for rotating the connecting shaft 13 includes a self-locking motor fixed to one side of the fixed plate 11 by bolts. The output shaft of the self-locking motor passes through the fixed plate 11 and is fixed to the connecting shaft 13. The self-locking motor has a self-locking function, eliminating the need for an additional locking device, thus effectively preventing accidental movement or loosening of the connecting shaft 13. The two tires are pushed sequentially along the inclined surface 5 on one side of the L-shaped frame 4 to the top of the L-shaped frame 4. Then, the power mechanism is activated to drive the connecting shaft 13 to rotate. The connecting shaft 13 drives the two take-up rollers 12 to rotate synchronously. The two take-up rollers 12 simultaneously take up the pull rope 19, thereby causing the L-shaped frame 4 to slide along the inner wall of one side of the fixed frame 2. The two tires at the top of the L-shaped frame 4 are lifted to the cutting mechanism position, eliminating the need for workers to carry the rubber tires to the cutting device, thus greatly reducing the labor intensity of workers and greatly increasing work efficiency.

[0024] In this invention, the outer wall of the top plate of the fixed frame 2 is provided with a cutting mechanism for cutting tires. The cutting mechanism includes a support frame 1 fixed to the top of the fixed frame 2 by bolts. Two telescopic rods 16 are welded to the inner walls of both sides of the support frame 1. A sliding plate 17 is welded to the other end of the two telescopic rods 16. A cutting blade 18 is detachably connected to one side of the sliding plate 17 by bolts. A drive mechanism is provided between the inner walls of both sides of the support frame 1 to drive the two sliding plates 17 to move towards each other. The drive mechanism includes a bidirectional lead screw 15 rotatably connected between the inner walls of both sides of the support frame 1 by bearings. A servo motor is welded to one side of the support frame 1 to drive the bidirectional lead screw 15 to rotate along the axial direction. When the servo motor is started, the output shaft of the servo motor drives the bidirectional lead screw 15 to rotate. The servo motor can realize the indirect rotation of the bidirectional lead screw 15. When the drive mechanism is started, the drive mechanism drives the two sliding plates 17 to move inward towards each other at the same time. The two sliding plates 17 respectively drive the two cutting blades 18 to move inward, so that the two tires are cut at the same time by the two cutting blades 18, thereby greatly increasing the working efficiency of the cutting device.

[0025] In this utility model, multiple limiting frames 3 are symmetrically arranged on the top of the L-shaped frame 4. Each of the multiple limiting frames 3 has an insertion mechanism for fixing the limiting frame 3. The insertion mechanism includes two through-type sliding grooves 10 opened on the top of the limiting frame 3. Insertion brackets 8 are slidably connected in the two sliding grooves 10. Multiple insertion holes 9 are opened on the top of the L-shaped frame 4 to cooperate with the insertion brackets 8. By inserting the insertion brackets 8 into the insertion holes 9, the limiting frame 3 can be quickly fixed and limited, so that the limiting frame 3 will not shift during use. The limiting frame 3 effectively prevents the tires of the L-shaped frame 4 from tipping over during the lifting and lowering process.

[0026] In particular, two baffles 7 are welded to the inner wall of the top plate of the fixing frame 2, and the baffles 7 are slidably connected to the stop block 6. The stop block 6 prevents the tire from shifting during the cutting process, thus preventing the tire from falling off and ensuring that the tire stays in the preset position, thereby enhancing the stability of the cutting process and improving the cutting accuracy.

[0027] Working principle: When needed, push the two tires sequentially along the inclined surface 5 on one side of the L-shaped frame 4 to the top of the L-shaped frame 4. Then, start the self-locking motor to drive the connecting shaft 13 to rotate. The connecting shaft 13 drives the two take-up rollers 12 to rotate synchronously. The two take-up rollers 12 simultaneously take up the pull rope 19, thereby causing the L-shaped frame 4 to slide along the inner wall of one side of the fixed frame 2. Lift the two tires at the top of the L-shaped frame 4 to the position of the cutting blade 18. Start the servo motor. The output shaft of the servo motor drives the bidirectional lead screw 15 to rotate. The bidirectional lead screw 15 drives the two slide plates 17 to move inwards towards each other simultaneously. The two slide plates 17 respectively drive the two cutting blades 18 to move inwards, and the two cutting blades 18 simultaneously cut the two tires.
