The clamping block moves closer to and contacts the inner wall of the tire, thereby realizing the fixed clamping of the inner wall of the tire, improving the stability of the tire during the trimming operation, providing a reliable guarantee for accurate trimming, reducing the trimming error and defective rate caused by the insecure fixation of the tire. The pressing rod moves downward to drive the rotating cylinder to move. When the rotating cylinder clamps the top of the tire, the bidirectional fixed clamping of the tire surface and inner wall is realized, further improving the stability of the tire during the trimming operation.

[0018] (2) The waste trimming device for rubber tire processing is threadedly connected between the reciprocating lead screw and the trimming box.

Without complex manual adjustment, the versatility and operating efficiency of the equipment are improved, and it can meet diverse production requirements, reducing the equipment idle rate.

[0019] (3) The waste trimming device for rubber tire processing contacts the second inclined block with the limiting rod. The movement of the second inclined block drives the limiting rod to move upward. At this time, the upward movement of the limiting rod realizes the limitation of the tire during the trimming operation, avoiding unnecessary movement or deviation due to the action of the blade, further ensuring the accuracy and safety of the trimming work, guaranteeing the trimming quality, and avoiding problems such as uneven trimming and dimensional deviation caused by the movement of the tire.

[0020] (4) For the waste trimming device for rubber tire processing, the waste cut off during tire trimming will move towards the waste collection box under the action of the rotation of the tire. The extrusion frame extrudes the tire waste accumulated inside the waste collection box, thereby reducing the volume. Reducing the waste volume facilitates subsequent collection and processing, and extends the processing cycle of the waste by the staff.

[0021] (5) The waste trimming device for rubber tire processing drives the push plate to move towards the extrusion frame by the rotation of the linkage rod to realize the pushing treatment of the waste, avoiding the situation of a large accumulation of waste inside the waste collection box and subsequent blockage, ensuring the smoothness of the waste collection area, reducing the frequency and workload of manual waste cleaning, making the entire trimming work process smoother and more efficient, and improving the continuity and automation degree of production.

[0039] The free end of the telescopic elastic rod 62 is fixedly connected to the hydraulic cylinder 55. When the hydraulic cylinder 55 moves downward, the telescopic elastic rod 62 is driven to move. At the same time, the telescopic elastic rod 62 moves downward and drives the inclined rod 63 to move downward. The end surface of the inclined rod 63 close to the processing disk 2 is provided with an inclined surface 1 for contacting and squeezing the inclined block 64 to move towards the direction close to the motor 56.

[0040] The surface of the inclined block 1 64 is provided with an inclined surface 2 for assisting the inclined rod 63 in bearing force. The inclined rod 63 slides through the top of the processing disk 2. The limit rod 66 contacts the surface of the inclined block 2 65.

The rotation of the transmission belt 1 drives the reciprocating screw rod 61 to rotate, because the reciprocating screw rod 61 is connected to the trimming box 54 by a threaded connection.

[0041] A waste treatment device for processing waste from tire trimming is provided on the surface of the diagonal rod 63. The waste treatment device includes a rack 71 fixedly installed on the surface of the diagonal rod 63. A rotating rod 72 is rotatably installed on the surface of the fixed frame 3. A gear 73 is fixedly installed on the circumferential surface of the rotating rod 72. An eccentric wheel 74 is fixedly installed on the circumferential surface of the rotating rod 72. A waste collection box 75 is fixedly installed on the top of the base 1. An extrusion frame 76 is slidably installed on the inner wall of the waste collection box 75. A push plate 77 is slidably installed on the bottom of the inner wall of the waste collection box 75. A linkage rod 78 is rotatably installed on the surface of the push plate 77. The rotation of the linkage rod 78 drives the push plate 77 to move towards the extrusion frame 76 to realize the pushing treatment of the waste.

[0042] Leakage holes are provided on the surface of the extrusion frame 76. The rack 71 meshes with the gear 73. The downward movement of the rack 71 drives the gear 73 to rotate. At the same time, the rotation of the gear 73 drives the rotating rod 72 to rotate.

[0043] The surface of the waste collection box 75 is set as the second arc surface. One end of the linkage rod 78 far from the push plate 77 is rotatably connected to the extrusion frame 76. The rotation of the linkage rod 78 drives the push plate 77 to move towards the extrusion frame 76 to realize the pushing treatment of the waste.

[0044] When this embodiment works: Start the first motor 4. The output end of the first motor 4 rotates to drive the first transmission belt to rotate. At the same time, the rotation of the first transmission belt drives the reciprocating lead screw 61 to rotate. Since the reciprocating lead screw 61 is threadedly connected to the trimming box 54, the rotation of the reciprocating lead screw 61 drives the second hydraulic cylinder 55 to move, realizing the rapid adaptation to tires of different sizes, thereby improving the operating efficiency of the equipment, eliminating the need for complex manual adjustment, improving the versatility and operating efficiency of the equipment, being able to meet diverse production requirements, reducing the equipment idle rate. When the second hydraulic cylinder 55 moves downward, it drives the first telescopic spring rod 62 to move. At the same time, the downward movement of the first telescopic spring rod 62 drives the diagonal rod 63 to move downward. The movement of the diagonal rod 63 contacts and presses the first inclined block 64 to move towards the second motor 56. At the same time, the movement of the first inclined block 64 drives the second inclined block 65 to move under the action of the diagonal rod 63. Since the second inclined block 65 contacts the limiting rod 66, the movement of the second inclined block 65 drives the limiting rod 66 to move upward. At this time, the upward movement of the limiting rod 66 realizes the limitation of the tire during the trimming operation, avoiding unnecessary movement or deviation due to the action of the blade, further ensuring the accuracy and safety of the trimming work, guaranteeing the trimming quality, and avoiding problems such as uneven trimming and dimensional deviation caused by the movement of the tire.

[0045] During the operation of this embodiment: The diagonal rod 63 moves downward under the action of the telescopic spring rod 62, driving the rack 71 to move. Since the rack 71 meshes with the gear 73, the downward movement of the rack 71 drives the gear 73 to rotate. At the same time, the rotation of the gear 73 drives the rotating rod 72 to rotate, and the rotation of the rotating rod 72 drives the eccentric wheel 74 to rotate. At this time, the rotating eccentric wheel 74 contacts and presses the extrusion frame 76 to move downward. At the same time, the waste material cut during the tire trimming will move towards the waste collection box 75 under the action of the tire rotation. The extrusion frame 76 squeezes the tire waste accumulated inside the waste collection box 75, thereby reducing the volume, making it convenient for subsequent collection and processing, extending the processing cycle of the waste by the staff. Subsequently, the eccentric wheel 74 continues to rotate, contacts and presses the extrusion frame 76 to move upward. At the same time, the upward movement of the extrusion frame 76 drives the linkage rod 78 to rotate. At the same time, the end of the linkage rod 78 close to the extrusion frame 76 rotates, driving the end of the linkage rod 78 close to the push plate 77 to rotate. At this time, the rotation of the linkage rod 78 drives the push plate 77 to move towards the extrusion frame 76 to realize the pushing treatment of the waste, avoiding the situation of a large amount of waste accumulation and blockage inside the waste collection box 75, ensuring the smoothness of the waste collection area, reducing the frequency and workload of manual waste cleaning, making the entire trimming work process smoother and more efficient, and improving the continuity and automation of production.
