Description

Technical Field

[0001] This utility model relates to the field of tire cold splicing technology, specifically a tire end cold splicing device. Background Technology

[0002] As a critical vehicle component, tires often require cold joining at both ends during use due to cutting, damage, or process requirements (such as customized tire splicing). Cold joining technology uses physical pressure to diffuse and bond the molecular chains at the rubber interface, achieving bonding without heating. It offers advantages such as energy saving, high efficiency, and simple process.

[0003] Currently, in existing technologies, the cold joining of tires is generally achieved by cutting the deflated tire end face, which produces adhesive rubber. The tire is then positioned and conveyed, and the cut end faces are bonded together. Finally, pressure is applied to achieve the cold joining of the two ends of the tire. However, in this process, since the tire end face is exposed to air after cutting, positioning and conveying the tire takes time. After the rubber oxidizes in the air for a period of time, it affects the subsequent adhesion of the rubber. Therefore, a tire end cold joining device is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a device for cold-joining both ends of a tire, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a tire end cold-jointing device, comprising a body and a controller. The body is equipped with a fixing mechanism and a support assembly. A fixing frame is fixedly mounted on the body, and a cutting and pressing mechanism is mounted on the fixing frame. The cutting and pressing mechanism includes:

[0006] An electric cylinder, wherein a U-shaped component is fixedly connected to the output end of the electric cylinder, and a guide rod is fixedly connected to the upper side of the U-shaped component;

[0007] A pressure block is rotatably connected to the inner surface of a U-shaped component. A stepper motor is fixedly connected to the outer wall of the U-shaped component, and the output shaft of the stepper motor is fixed to the pressure block.

[0008] The cutter is fixedly installed on the outer wall of the pressure block. There are two sets of cutters, which are arranged at an angle and parallel to each other. By lowering the two sets of cutters, the end face of the tire can be cut. After the cut is completed, the cut end faces of the two sets of tires are brought together by the fixing mechanism. Then, the stepper motor is started to make the pressure block flip down. Then, the electric cylinder drives the cut end face of the tire to apply pressure. The tire end face is exposed to air for a short time after cutting, which ensures the subsequent bonding effect of the cut end face of the tire.

[0009] Preferably, the electric cylinder is fixedly connected to the fixed frame, and the guide rod passes through the fixed frame and is slidably connected to the fixed frame.

[0010] Preferably, the fixing mechanism includes a bidirectional lead screw, which is rotatably connected in a groove, and a movable block is threaded onto the bidirectional lead screw. A fixing component is provided on the upper side of the movable block.

[0011] Preferably, the fixing component includes a movable plate, which is fixed to a movable block. A connecting frame is fixedly connected to the outer wall of the movable plate, and a screw is threadedly connected to the connecting frame. A pressure plate is rotatably connected to the bottom of the screw, and a round rod is fixedly connected to the pressure plate. The round rod passes through the connecting frame and is slidably connected to the connecting frame. By driving the screw to rotate, the movable block drives the movable plate to move, which can transport the tire end face to below the pressure block.

[0012] Preferably, the support assembly includes a placement plate, a limiting rod is slidably connected to the placement plate, a guide rail is fixedly connected to the end of the limiting rod away from the placement plate, and a positioning component is provided on the guide rail.

[0013] Preferably, the placement plate has a through groove that matches the limiting rod, allowing the limiting rod to retract and enter.

[0014] Preferably, the positioning component includes a positioning block, a clamping bolt threaded onto the positioning block, and a rotating wheel rotatably connected to the positioning block. By using the positioning block, tires of different widths can be positioned.

[0015] This utility model provides a device for cold-joining both ends of a tire. It has the following beneficial effects:

[0016] (1) The combination of the fixing mechanism, support components and cutting and pressing mechanism of the tire end cold bonding equipment allows the stepper motor to flip the pressure block to start the pressing process after the electric cylinder drives the cutter to complete the tire end face cutting. This avoids the intermediate links of transportation and positioning after cutting in the traditional process, greatly shortens the time the tire end face is exposed to the air, reduces rubber oxidation and dust adsorption, ensures the adhesion of the cut surface, and improves the subsequent cold bonding effect.

[0017] (2) The tire end cold splicing equipment uses a bidirectional screw to drive the moving block, which can simultaneously adjust the position of the two sets of tires, making it convenient to connect the tire end faces later. With the adjustable positioning block and clamping bolt in the positioning component, it can adapt to the precise centering of tires of different widths. The rotating wheel assists in the tire conveying, ensuring the precise connection of the cut end faces, making the cold splicing surfaces fit tightly, and ensuring the cold splicing effect of the tires later.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-7 This utility model proposes a tire end cold-jointing device, including a body 1 and a controller 2. The body 1 is provided with a fixing mechanism 3 and a support component 4. A fixing frame 5 is fixedly installed on the body 1, and a cutting and pressing mechanism 6 is provided on the fixing frame 5.

[0034] In an embodiment of this utility model, in order to fix the deflated tire, the fixing mechanism 3 specifically includes a bidirectional lead screw 31, which is rotatably connected in a groove 32. A movable block 33 is threadedly connected to the bidirectional lead screw 31. A fixing component 34 is provided on the upper side of the movable block 33. The fixing component 34 includes a movable plate 341, which is fixed to the movable block 33. A connecting frame 342 is fixedly connected to the outer wall of the movable plate 341. A screw 343 is threadedly connected to the connecting frame 342. A pressure rod is rotatably connected to the bottom of the screw 343. A round rod 345 is fixedly connected to the plate 344 and the pressure plate 344. The round rod 345 passes through the connecting frame 342 and is slidably connected to the connecting frame 342. By passing the tire through the connecting frame 342 and then rotating the screw 343, the pressure plate 344 is pressed down under the guidance of the round rod 345 to press the tire. At the same time, the bidirectional lead screw 31 is driven to rotate. Its power source is a motor drive. Under the limiting action of the groove 32 on the moving block 33, the moving block 33 drives the moving plate 341 to move, so that the tire can be transported to the bottom of the cutting and pressing mechanism 6.

[0035] Furthermore, the support assembly 4 includes a placement plate 41, on which a limiting rod 42 is slidably connected. A guide rail 43 is fixedly connected to the end of the limiting rod 42 away from the placement plate 41. The guide rail 43 and the placement plate 41 are elastically connected by a return spring. The placement plate 41 is fixed to the machine body 1. A positioning assembly 44 is provided on the guide rail 43. A through groove matching the limiting rod 42 is opened on the placement plate 41, allowing the limiting rod 42 to retract and enter. The positioning assembly 44 includes a positioning block 441, on which a clamping bolt 442 is threadedly connected. A rotating wheel 443 is rotatably connected to the positioning block 441. By rotating the clamping bolt 442, the position of the positioning block 441 can be adjusted, which facilitates the positioning of tires of different sizes. The use of the rotating wheel 443 also assists in the transportation of tires.

[0036] Furthermore, the cutting and pressing mechanism 6 includes an electric cylinder 61, a pressure block 64, and a cutter 65. A U-shaped component 63 is fixedly connected to the output end of the electric cylinder 61, and a guide rod 62 is fixedly connected to the upper side of the U-shaped component 63. The electric cylinder 61 is fixedly connected to the fixed frame 5, and the guide rod 62 passes through the fixed frame 5 and is slidably connected to the fixed frame 5. The pressure block 64 is rotatably connected to the inner surface of the U-shaped component 63. A stepper motor 66 is fixedly connected to the outer wall of the U-shaped component 63, and the output shaft of the stepper motor 66 is fixed to the pressure block 64. The cutter 65 is fixedly installed on the outer wall of the pressure block 64. Two sets of cutters 65 are provided, and the two sets of cutters 65 are arranged at an angle and parallel. When the tire is conveyed to the placement plate 41, the electric cylinder 61 is activated, and the output end of the electric cylinder 61 drives the U-shaped component 63 to descend. Then, the cutter 65 cuts the end face of the tire, exposing a new inclined end face, which facilitates increasing the area for subsequent cold bonding. At the same time, the new end face has better adhesion. Then, through the rotation of the bidirectional lead screw 31, the cut end faces of the two sets of tires approach each other until they abut. During this process, the moving plate 341 can squeeze the guide rail 43, causing the return spring to contract. After the cut end faces of the two sets of tires abut, the stepper motor 66 is started. The output shaft of the stepper motor 66 drives the pressure block 64 to rotate. Then, the output end of the electric cylinder 61 drives the U-shaped part 63 to descend, so that the pressure block 64 applies pressure to the cut end faces of the two sets of tires, realizing cold bonding. This greatly shortens the time that the tire end face is exposed to air, reduces rubber oxidation and dust adsorption, ensures the adhesion of the cut surface, and improves the subsequent cold bonding effect.

[0037] It should be noted that all the electrical components mentioned above are existing technology products. Those skilled in the art should select, install, and debug the circuits according to their needs to ensure that all electrical appliances function properly. All components are general standard parts or parts known to those skilled in the art, and their structures and principles can be obtained by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are imposed here.

[0038] In use, the tire is passed through the connecting frame 342, and then the screw 343 is rotated. Under the guidance of the round rod 345, the pressure plate 344 is pressed down to compress the tire. At the same time, the double-acting screw 31 is driven to rotate, and under the limiting action of the groove 32 on the moving block 33, the moving block 33 drives the moving plate 341 to move, thereby allowing the tire to be transported to the area below the cutter 65. During this process, the position of the positioning block 441 can be adjusted by rotating the clamping bolt 442 to position tires of different sizes. The use of the rotating wheel 443 assists in the transport of the tire, and the electric cylinder 61 is activated. The output end of the electric cylinder 61 drives the U-shaped part 63 to descend, and then the cutter 65 cuts the end face of the tire, exposing a new inclined end face. Then, through the rotation of the bidirectional lead screw 31, the cut end faces of the two sets of tires approach each other until they abut. During this process, the moving plate 341 can squeeze the guide rail 43, causing the return spring to contract. After the cut end faces of the two sets of tires abut, the stepper motor 66 is started. The output shaft of the stepper motor 66 drives the pressure block 64 to flip. Then, the output end of the electric cylinder 61 is started to drive the U-shaped part 63 to descend, so that the pressure block 64 applies pressure to the cut end faces of the two sets of tires to achieve cold joining.
