Description

Technical Field

[0001] The present invention relates to the technical field of tire processing, and particularly to a device for pressing a composite joint. Background Art

[0002] In the all-steel market, the feedback is increasing day by day. Among them, side bulging at the joint is more serious, posing a potential risk of tire blowout. It is urgent to improve the quality of the composite joint. One of the reasons for side bulging is that the composite joint is opened, resulting in abnormal arrangement and uneven density of cord at this place, causing side bulging. At present, the forming machine uses a crimping device to press, which is pushed straight forward by a cylinder for pressing. The pressing effect of the crimping device is poor, and the composite joint is prone to cracking, resulting in uneven cord density and the risk of side bulging at the joint.

[0003] Based on this, a device for pressing a composite joint is now provided, which can eliminate the drawbacks of the existing device. Summary of the Invention

[0004] The purpose of the present invention is to provide a device for pressing a composite joint, which solves the problem of poor pressing effect of tires in the prior art.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figures 1 - 5 shown, the embodiment of the present invention provides a device for pressing a composite joint, including a pressing seat 100. The pressing seat 100 is of a U-shaped structure. Two pressing cylinders 300 are provided on one side of the pressing seat 100 facing the tire surface. A plurality of pressing columns 301 are distributed on the surfaces of the two pressing cylinders 300. The end of the pressing column 301 is of a hemispherical structure. The pressing cylinder 300 is rotatably arranged at the end of the flipping frame 206. The central position of the flipping frame 206 is rotatably connected to the flipping shaft 207. Both ends of the flipping shaft 207 are connected to the pressing seat 100 through cross bars. The other ends of the two flipping frames 206 are connected to a pushing assembly for driving their rotation. The pushing assembly can drive the pressing cylinder 300 to move towards the tire, thereby adjusting the pressing force. The pressing seat 100 is connected to a reciprocating driving assembly for driving it to reciprocate along the tire pressing position. During use, the reciprocating moving assembly drives the pressing cylinder 300 to reciprocate along the tire pressing position, and the pushing assembly drives the flipping frame 206 to rotate, so that the pressing cylinder 300 can better press the tire surface, and the pressing column 301 can squeeze the tire surface, making multiple tire surfaces fit better;

[0026] Inside the pressing cylinder 300, there is an installation cavity 305. Inside the installation cavity 305, a plurality of guiding connecting rods 309 are arranged in an array. The guiding connecting rods 309 are connected to the pressing columns 301 on the same generatrix. The guiding connecting rods 309 are connected to the inner wall of the installation cavity 305 through a plurality of return springs 308. The pressing columns 301 are slidably matched with the sliding holes on the surface of the pressing cylinder 300. Under the action of the return springs 308, the pressing columns 301 will retract into the installation cavity 305. Inside the installation cavity 305, there is a guiding member that presses against the guiding connecting rods 309. Through the guiding member, the guiding connecting rods 309 move towards the inner wall of the installation cavity 305, so that the pressing columns 301 pass through the outside of the pressing cylinder 300 to press the surface of the tire. As the pressing cylinder 300 rotates, when the pressing columns 301 are away from the tire, at this time, the guiding member will not generate a driving force on the guiding connecting rods 309. Under the action of the return springs 308, the pressing columns 301 will retract into the installation cavity 305 again. The attachments on the surface of the pressing columns 301 will be scraped off and remain on the surface of the pressing cylinder 300, which is convenient for later cleaning operations;

[0027] The guiding member includes a guiding pressing ring 303. The guiding pressing ring 303 is located at a position deviating from the axis of the pressing cylinder 300 and is arranged close to the tire side. A central rod 307 is provided at the diameter position of the guiding pressing ring 303. The eccentric position of the central rod 307 is connected to a locking shaft 304. The locking shaft 304 is coaxially arranged with the guiding pressing ring 303. The locking shaft 304 passes through the perforation at the end of the pressing cylinder 300. The end of the locking shaft 304 is connected to one end of a positioning connecting rod 306. The other end of the positioning connecting rod 306 is connected to a positioning pin 302. The positioning pin 302 is coaxially arranged with the rotation center of the flipping frame 206. In this way, whether the pressing cylinder 300 rotates or not, the positioning pin 302 and the positioning connecting rod 306 will lock the state of the locking shaft 304 and will not allow the guiding pressing ring 303 to rotate, so that the pressing columns 301 can be guided to extend;

[0028] A rotating pressing ring 310 is rotatably arranged on the outside of the guiding pressing ring 303. A wear-resistant layer is provided on the outside of the rotating pressing ring 310. The rotating pressing ring 310 is in pressing contact with the surface of the guiding connecting rod 309, so that the guiding connecting rod 309 can obtain power for displacement;

[0029] The reciprocating drive assembly includes two displacement sliders 101 provided on the pressing seat 100. A displacement guide rod 103 is slidably provided on the displacement slider 101. Both ends of the displacement guide rod 103 are connected to a displacement base 104. A displacement screw 102 is also threadedly provided on the displacement slider 101. One end of the displacement screw 102 is rotatably connected to the displacement base 104, and the other end of the displacement screw 102 passes through a through hole on the displacement base 104 and is connected to the output end of a displacement motor 105. Driven by the displacement motor 105, the displacement screw 102 and the displacement slider 101 rotate relative to each other. Under the action of the thread, the displacement slider 101 can slide along the displacement guide rod 103, thereby providing power for the reciprocating movement of the pressing seat 100;

[0030] The pushing assembly includes an adjustment slider 201 slidably provided on the surface of the pressing seat 100. A waist-shaped transmission groove 205 is formed on the adjustment slider 201. A transmission rod 204 is rotatably provided at the end of the flipping frame 206. The transmission rod 204 is slidably matched with the waist-shaped transmission groove 205. A transmission screw hole is formed on the adjustment slider 201, and an adjustment shaft 203 is fitted in the transmission screw hole. Both ends of the adjustment shaft 203 are rotatably connected to the pressing seat 100. Two adjustment threads 202 with opposite helix directions are provided on the adjustment shaft 203. The adjustment threads 202 are threadedly connected to the adjustment slider 201. An adjustment motor 200 for driving the adjustment shaft 203 to rotate is provided outside the pressing seat 100. By driving the adjustment shaft 203 to rotate relative to the adjustment slider 201 by the adjustment motor 200, under the action of the thread, the two adjustment sliders 201 slide on the surface of the pressing seat 100, thereby driving the flipping frame 206 to rotate around the flipping shaft 207. In this way, the pressing distance of the pressing column 301 can be adjusted to match different tires. Moreover, screw transmission is adopted here, which has a self-locking effect and ensures the pressing quality.

[0031] Working principle: When in use, by driving the adjustment shaft 203 to rotate relative to the adjustment slider 201 by the adjustment motor 200, under the action of the thread, the two adjustment sliders 201 slide on the surface of the pressing seat 100, thereby driving the flipping frame 206 to rotate around the flipping shaft 207. In this way, the pressing distance of the pressing column 301 can be adjusted to match different tires. Moreover, screw transmission is adopted here, which has a self-locking effect and ensures the pressing quality. Driven by the displacement motor 105, the displacement screw 102 and the displacement slider 101 rotate relative to each other. Under the action of the thread, the displacement slider 101 can slide along the displacement guide rod 103, thereby providing power for the reciprocating movement of the pressing seat 100;

[0032] As the pressing cylinder 300 rotates, when the pressing column 301 moves away from the tire, the guide member will not generate a pushing force on the guide link 309. Under the action of the return spring 308, the pressing column 301 will be re-entered into the installation cavity 305, and the attachments on the surface of the pressing column 301 will be scraped off and retained on the surface of the pressing cylinder 300, which is convenient for subsequent cleaning operations.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
