Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire processing technology, and in particular to a device for pressing composite joints. Background Technology
[0002] Feedback from the all-steel market is increasing, with the most serious issue being side bulging at the joints, posing a potential risk of tire blowout. There is an urgent need to improve the quality of composite joints. One of the reasons for side bulging is that the composite joints cause abnormal and uneven arrangement of the cords, resulting in bulging. Currently, the forming machine uses a presser for pressing, which is performed by a cylinder pushing forward. The presser has poor pressing effect, and the composite joints are prone to cracking, resulting in uneven cord density and the risk of side bulging at the joints.
[0003] Based on this, a device for pressing composite joints is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
[0004] The purpose of this invention is to provide a device for pressing composite joints, which solves the problem of poor tire pressing effect in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0024] 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.
[0025] like Figures 1-5 As shown, this utility model embodiment provides a device for pressing composite joints, including a pressing seat 100, which has a U-shaped structure. Two pressing cylinders 300 are provided on the side of the pressing seat 100 facing the tire surface. Multiple pressing posts 301 are distributed on the surface of the two pressing cylinders 300. The ends of the pressing posts 301 are hemispherical. The pressing cylinders 300 are rotatably mounted at the ends of a flipping frame 206. The center of the flipping frame 206 is rotatably connected to a flipping shaft 207. Both ends of the flipping shaft 207 are connected to the pressing seat 100 via crossbars. The other end of the flipping frame 206 is connected to a pushing component for driving its rotation. The pushing component can drive the pressing cylinder 300 to move toward the tire, thereby adjusting the pressing force. The pressing seat 100 is connected to a reciprocating drive component for driving it to move back and forth along the tire pressing position. In use, the reciprocating drive component drives the pressing cylinder 300 to move back and forth along the tire pressing position, and the pushing component drives the flipping frame 206 to rotate, so that the pressing cylinder 300 can better press the tire surface. The pressing column 301 can squeeze the tire surface, so that multiple tire surfaces fit together better.
[0026] The pressing cylinder 300 has an internal mounting cavity 305. Multiple guide rods 309 are arrayed within the mounting cavity 305. Each guide rod 309 is connected to a pressing column 301 on the same generatrix. The guide rods 309 are connected to the inner wall of the mounting cavity 305 via multiple return springs 308. The pressing column 301 slides within a sliding hole on the surface of the pressing cylinder 300. Under the action of the return springs 308, the pressing column 301 retracts into the mounting cavity 305. The mounting cavity 305 contains a mechanism for generating pressure on the guide rods 309. The guide member presses against the tire surface. The guide member causes the guide rod 309 to move toward the inner wall of the mounting cavity 305, so that the pressing column 301 passes through the outside of the pressing cylinder 300 and presses against the tire surface. As the pressing cylinder 300 rotates, when the pressing column 301 moves away from the tire, the guide member will not exert a pushing force on the guide rod 309. Under the action of the return spring 308, the pressing column 301 will retract into the mounting cavity 305. The adhering material on the surface of the pressing column 301 will be scraped off and remain on the surface of the pressing cylinder 300, which is convenient for subsequent cleaning operations.
[0027] The guide includes a guide ring 303, which is offset from the axis of the pressing cylinder 300 and positioned closer to the tire. A central rod 307 is located at the diameter of the guide ring 303. The central rod 307 is eccentrically connected to a locking shaft 304. The locking shaft 304 is coaxial with the guide ring 303 and passes through a through hole at the end of the pressing cylinder 300. The end of the locking shaft 304 is connected to one end of a positioning rod 306, and the other end of the positioning rod 306 is connected to a positioning pin 302. The positioning pin 302 is coaxial with the rotation center of the flipping frame 206. In this way, regardless of whether the pressing cylinder 300 rotates or not, the positioning pin 302 and the positioning rod 306 will lock the locking shaft 304, preventing the guide ring 303 from rotating. This allows the pressing column 301 to extend.
[0028] A rotating pressure ring 310 is rotatably provided on the outer side of the guide pressure ring 303. The outer side of the rotating pressure ring 310 is provided with a wear-resistant layer. The rotating pressure ring 310 is in abutting contact with the surface of the guide connecting rod 309, thereby enabling the guide connecting rod 309 to move and obtain power.
[0029] The reciprocating drive assembly includes two displacement sliders 101 disposed on the pressing base 100. A displacement guide rod 103 is slidably disposed on each displacement slider 101. Both ends of the displacement guide rod 103 are connected to the displacement base 104. A displacement screw 102 is also threaded onto each 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 in the displacement base 104 and is connected to the output end of the displacement motor 105. Under the drive of the displacement motor 105, the displacement screw 102 rotates relative to the displacement slider 101. 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 base 100.
[0030] The pushing assembly includes an adjusting slider 201 slidably disposed on the surface of the pressing seat 100. The adjusting slider 201 has a waist-shaped transmission groove 205. A transmission rod 204 is rotatably disposed at the end of the flipping frame 206. The transmission rod 204 and the waist-shaped transmission groove 205 are slidably matched. The adjusting slider 201 has a transmission screw hole, in which an adjusting shaft 203 is fitted. Both ends of the adjusting shaft 203 are rotatably connected to the pressing seat 100. The adjusting shaft 203 has two adjusting threads 202 with opposite directions of rotation. 202 is threadedly connected to the adjusting slider 201. The outer side of the pressing seat 100 is provided with an adjusting motor 200 for driving the adjusting shaft 203 to rotate. The adjusting motor 200 drives the adjusting shaft 203 and the adjusting slider 201 to rotate relative to each other. Under the action of the thread, the two adjusting 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. In addition, the threaded transmission has a self-locking effect, which ensures the pressing quality.
[0031] Working principle: During use, the adjusting motor 200 drives the adjusting shaft 203 and the adjusting slider 201 to rotate relative to each other. Under the action of the thread, the two adjusting sliders 201 slide on the surface of the pressing seat 100, thereby driving the flipping frame 206 to rotate around the flipping shaft 207. This allows adjustment of the pressing distance of the pressing column 301 to match different tires. The use of threaded transmission here has a self-locking effect, ensuring 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 will not exert a pushing force on the guide rod 309. Under the action of the return spring 308, the pressing column 301 will retract into the mounting cavity 305. The adhering substances on the surface of the pressing column 301 will be scraped off and remain on the surface of the pressing cylinder 300, which will facilitate subsequent cleaning operations.
[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
