Description

Technical Field

[0001] This utility model relates to the technical field of piston-driven structure for pressure rollers in tire forming machines, and in particular to a piston-driven structure for pressure rollers in tire forming machines. Background Technology

[0002] Tire forming machines are core equipment in the tire manufacturing process, used to bond materials such as rubber, cord fabric, and steel wire layer by layer to assemble a semi-finished tire blank. Their process directly affects the tire's strength, uniformity, and durability.

[0003] Existing tire forming machines use pressure rollers with piston structures and shaping rings to shape the tire tread. The piston-driven structure of the pressure rollers can squeeze the shaping rings, causing some of the shaping rings to protrude and contact the tire. However, because the existing piston-driven mechanism of the pressure rollers cannot precisely limit the position of the shaping rings, it is impossible to achieve one piston for one shaping ring. Therefore, if the number of protruding shaping rings is inconsistent with the actual usage requirements, it may cause a reduction in the quality of the tire tread forming process. To address this, we provide a pressure roller piston-driven structure for a tire forming machine. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing tire forming machine pressure roller piston pushing structures, which cannot limit the position of the shaping ring used in conjunction with the roller, and to provide a tire forming machine pressure roller piston pushing structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a piston-pushing structure for a tire forming machine pressure roller, comprising: a forming mechanism, the forming mechanism including a pressure roller body, a pressing mechanism provided at the top of the pressure roller body, the pressing mechanism including a crossbar, a circular block sleeved inside the crossbar, a pressing block fixedly connected to one side of the circular block, a locking pin sleeved inside the crossbar and the circular block, a moving block fixedly connected to one end of the locking pin, a spring provided on one side of the moving block, guide blocks fixedly connected to both sides of the moving block, a push block fixedly connected to the top of the moving block, a slider provided at the bottom of the circular block, and mounting mechanisms provided at both ends of the crossbar.

[0006] In a preferred embodiment, the circular block is slidably connected to the crossbar, the locking pin is slidably connected to both the crossbar and the circular block, the movable block is sleeved inside the circular block, the movable block is slidably connected to the circular block, and the two ends of the spring are respectively fixedly connected to the outer surface of the movable block and the inner wall of the circular block.

[0007] In a preferred embodiment, the guide block is fitted into a guide groove inside the circular block, and the guide block is slidably connected to the circular block.

[0008] In a preferred embodiment, the slider is sleeved inside the crossbar, the slider is slidably connected to the crossbar, and the slider is fixedly connected to the circular block.

[0009] In a preferred embodiment, the mounting mechanism includes a fixing block, which is fixedly connected to the pressure roller body. An insert block is sleeved inside the fixing block, and the insert block is slidably connected to the fixing block.

[0010] In a preferred embodiment, the embedded block is fixedly connected to the crossbar, and bolts are sleeved inside the fixed block and the embedded block, with the bolts slidably connected to the fixed block.

[0011] In a preferred embodiment, the bolt is threadedly connected to the insert block, and one end of the bolt is provided with a knob, which is fixedly connected to the bolt.

[0012] In a preferred embodiment, a shaping ring is fitted onto the outer surface of the pressure roller body, and the shaping ring is slidably connected to the pressure roller body.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] This invention features an extrusion mechanism with adjustable positions for the circular block and locking pin. A locking hole, matching the locking pin, is provided on the crossbar. Furthermore, the distance between the centers of adjacent locking holes matches the size of the shaping ring. Therefore, after adjusting the position of the circular block, the shaping ring can be fitted and limited, allowing each shaping ring to correspond one-to-one with a piston on the pressure roller. When the piston extends, it drives the mating shaping ring, causing a certain number of rings to protrude, thus shaping a type of tire platform. A connecting mechanism is also included, which works in conjunction with the extrusion mechanism to ensure proper positioning and installation, and maintains absolute stability after installation.

[0023] 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.

[0024] Example 1

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: a piston pushing structure for a tire forming machine pressure roller, comprising: a forming mechanism 1, the forming mechanism 1 including a pressure roller body 11, a pressing mechanism 2 provided on the top of the pressure roller body 11, the pressing mechanism 2 including a crossbar 21, a circular block 22 sleeved inside the crossbar 21, a pressing block 23 fixedly connected to one side of the circular block 22, a locking pin 24 sleeved inside the crossbar 21 and the circular block 22, a moving block 25 fixedly connected to one end of the locking pin 24, a spring 26 provided on one side of the moving block 25, guide blocks 27 fixedly connected to both sides of the moving block 25, and a push block 28 fixedly connected to the top of the moving block 25. The bottom of the circular block 22 is provided with a slider 29, and both ends of the crossbar 21 are provided with mounting mechanisms 3. The circular block 22 is slidably connected to the crossbar 21. The locking post 24 is slidably connected to both the crossbar 21 and the circular block 22. The moving block 25 is sleeved inside the circular block 22 and is slidably connected to the circular block 22. The two ends of the spring 26 are respectively fixedly connected to the outer surface of the moving block 25 and the inner wall of the circular block 22. The guide block 27 is sleeved in the guide groove opened inside the circular block 22 and is slidably connected to the circular block 22. The slider 29 is sleeved inside the crossbar 21 and is slidably connected to the crossbar 21. The slider 29 is fixedly connected to the circular block 22.

[0026] In this embodiment, by setting extrusion blocks 23, which can fit against the shaping rings 12 after movement, and by providing extrusion blocks 23 at both ends of the crossbar 21, a certain number of shaping rings 12 can be in a fitted state under the action of the two extrusion blocks 23. Furthermore, by setting locking posts 24, which can engage inside the crossbar 21, the round blocks 22 and extrusion blocks 23 can maintain a stable working state under the action of the locking posts 24. The distance between the adjacent locking holes on the crossbar 21 that fit with the locking posts 24 is suitable for the size of the shaping rings 12. Therefore, the pressure roller... When the piston inside the body 11 is ejected, it can make contact with the center of the inner wall of the shaping ring 12, so that a certain number of pistons can drive a certain number of shaping rings 12 to move and adjust. A moving block 25 and a spring 26 are provided. When the moving block 25 moves, it can compress the spring 26, so that the spring 26 generates elastic force. The elastic force of the spring 26 can act on the locking post 24, so that the locking post 24 can be tightly locked into the interior of the crossbar 21. In addition, a slider 29 is provided, and the slider 29 is sleeved inside the crossbar 21, so that the crossbar 21 can guide the sliding of the round block 22.

[0027] Example 2

[0028] like Figures 1-5 As shown, the installation mechanism 3 includes a fixing block 31, which is fixedly connected to the pressure roller body 11. An embedded block 32 is sleeved inside the fixing block 31 and is slidably connected to the fixing block 31. The embedded block 32 is fixedly connected to the crossbar 21. Bolts 33 are sleeved inside the fixing block 31 and the embedded block 32 and are slidably connected to the fixing block 31. Bolts 33 are threadedly connected to the embedded block 32. A knob 34 is provided at one end of the bolt 33 and is fixedly connected to the bolt 33. A shaping ring 12 is sleeved on the outer surface of the pressure roller body 11 and is slidably connected to the pressure roller body 11.

[0029] In this embodiment, by setting a fixing block 31, and opening a positioning groove on the fixing block 31 that matches the embedding block 32, the extrusion mechanism 2, which is fixedly connected to the embedding block 32, can be positioned and installed. Thus, the entire extrusion mechanism 2 can be in the proper position after installation, and can cooperate with the installation and use of the shaping ring 12. By setting a bolt 33 and a knob 34, and threading the bolt 33 to the embedding block 32, the extrusion mechanism 2 can be easily installed and removed.

[0030] Working principle:

[0031] like Figures 1-5As shown, in use, the extrusion mechanism 2 can be installed first. The embedded block 32 is placed inside the fixed block 31. Then, the knob 34 drives the bolt 33 into the fixed block 31 and the embedded block 32, and the bolt 33 is threadedly connected to the embedded block 32. Thus, the extrusion mechanism 2 can be used stably. A certain number of shaping rings 12 are then fitted onto the outer surfaces of the pressure roller body 11 and the crossbar 21 and used. Then, one of the extrusion blocks 23 is moved. First, the push block 28 is slid, which drives the moving block 25 to slide inside the circular block 22. Guided by the guide block 27, the moving block 25 compresses the spring 26, causing the spring 26 to generate elastic force until the locking post 24 disengages from the locking hole on the crossbar 21. Then, the circular block 22 is slid, and guided by the slider 29, it drives the extrusion block 23 to move simultaneously, allowing the extrusion block 23 to move. 3. Gradually approach the shaping ring 12 and stop moving at the locking hole on a crossbar 21 near the shaping ring 12. Then release the push block 28. At this time, the elastic force of the spring 26 will be released instantly, and the elastic force of the spring 26 will reset the moving block 25 and the locking post 24, so that the locking post 24 can be locked into the interior of the crossbar 21 again. At this time, push multiple shaping rings 12 so that one of the shaping rings 12 is in contact with the extrusion block 23. Then move the other extrusion block 23 in the same way so that the two extrusion blocks 23 work together to limit a certain number of shaping rings 12. At this time, the shaping rings 12 will correspond one-to-one with the pistons set on the pressure roller body 11. When the pistons on the pressure roller body 11 move, they can push the shaping rings 12 so that some of the shaping rings 12 can be in the protruding position. Thus, the tire forming machine can use the pressure roller body 11 and the shaping rings 12 to shape the tire platform.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
