Description

Technical Field

[0001] This utility model relates to the field of tire forming machines, and in particular to a tire forming machine pressure roller anti-deviation guide structure. Background Technology

[0002] A tire forming machine is a device used to assemble the various components of a tire (such as the tread, carcass, and sidewalls) into the final tire shape through a series of processing steps. Its main functions include tire pressing, forming, heating, and cooling processes to ensure that the tire's structure and performance meet design requirements.

[0003] Existing technologies, such as the utility model with publication number CN203391327U, disclose a pressure roller for a tire forming machine. This patent employs a rear pressure roller and a lower pressure roller connected by a lead screw on the same horizontal track. The rear pressure roller moves back and forth relative to the lower pressure roller under the drive of the lead screw. A forming drum is located above the rear and lower pressure rollers, and the lower pressure roller drives the rear pressure roller to move back and forth relative to the forming drum. The beneficial effect of this utility model is that the rear and lower pressure rollers can move automatically when not in operation, solving the problem of pressure rollers avoiding the transmission ring in the forming machine and improving the production process.

[0004] The inventors discovered in their daily work that, in the prior art, when operators use the pressure roller body to press the tires on the roller, the pressure distribution is uneven during the movement of the pressure roller body, causing the pressure roller body to deviate from the predetermined trajectory. This leads to instability in the pressing process, affecting the uniformity and final quality of the tires, and further increasing the uncertainty in the production process and equipment wear.

[0005] Therefore, it is necessary to provide a new anti-deviation guide structure for the pressure roller of a tire forming machine to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies where uneven pressure distribution during roller movement leads to roller offset, resulting in unstable pressing, affecting tire quality, and increasing equipment wear. Therefore, this invention proposes a roller anti-offset guide structure for tire forming machines.

[0007] To solve the above technical problems, this utility model provides a guide structure for preventing the deflection of a pressure roller in a tire forming machine, comprising: a base plate and a limiting structure. The upper surface of the base plate is equipped with a tire forming machine body and two positioning devices. A control device is installed on one side of the tire forming machine body. An operating roller is installed inside the tire forming machine body, and the arc surface of the operating roller is provided with several tire bead rings. The upper surface of the base plate is equipped with the limiting structure, which includes two fixing plates and a fixing block. The two fixing plates are fixedly connected to the base plate, and the fixing block is fixedly connected to the base plate. A limiting groove is formed on the inner wall of the fixing plate, and a connecting block is slidably connected to the inner wall of the limiting groove. The two connecting blocks are fixedly connected on their adjacent sides. The device is equipped with connecting blocks, two of which are rotatably connected to the pressure roller body. An auxiliary rod is fixedly connected to the inner wall of the fixed block, and a connecting plate is rotatably connected to the arc surface of the auxiliary rod. A connecting rod is rotatably connected to the inner wall of the connecting plate, and a connecting plate is rotatably connected to the arc surface of the connecting rod. Fixed frames are fixedly connected to both ends of the connecting rod. An mounting plate is fixedly connected to the side of the two fixed plates away from the fixed frames. A cylinder is fixedly connected to the side of the mounting plate away from the fixed frames. The arc surface of the cylinder output end is slidably connected to the mounting plate, and the cylinder output end is fixedly connected to the fixed frame. A moving plate is fixedly connected to the side of the two connecting blocks that are close to each other. A positioning block is fixedly connected to the lower surface of the moving plate, and a fixing rod is fixedly connected to the inner wall of the positioning block. The fixing rod is rotatably connected to the connecting plate.

[0008] The effect achieved by the above components is that when personnel need to press the tire on the operating roller, they can activate the cylinder to move the fixed frame closer to the mounting plate until the pressure roller body comes into contact with the tire on the operating roller. Then, the personnel can activate the operating roller to press the tire on the operating roller. This can prevent the pressure roller body from shifting during the movement and improve the stability of the pressure roller body during the movement.

[0009] Preferably, a limiting rod is fixedly connected to the inner wall of the limiting groove, and the limiting rod is slidably connected to the connecting block.

[0010] The effect achieved by the above components is that the limiting rod can limit the connecting block and prevent the connecting block from becoming misaligned during the sliding process on the inner wall of the limiting groove.

[0011] Preferably, a protective pad is fixedly connected to the upper surface of the connecting block, and the protective pad is slidably connected to the limiting groove.

[0012] The effect achieved by the above components is that the protective pad can protect the connecting block and prevent the upper surface of the connecting block from directly contacting the top wall of the limiting groove.

[0013] Preferably, the movable plate is a stainless steel plate, and the cross-section of the movable plate is rectangular.

[0014] The effect achieved by the above components is that the stainless steel plate has high strength and good wear resistance, which can prevent the moving plate from deforming during short-term use.

[0015] Preferably, the tire forming machine body has an auxiliary structure on the side near the operating roller. The auxiliary structure includes an auxiliary plate and a connecting frame. The auxiliary plate is fixedly connected to the tire forming machine body, and the connecting frame is fixedly connected to the tire forming machine body. An installation rod is fixedly connected to the inner wall of the connecting frame. An adjusting block is slidably connected to the arc surface of the installation rod. A spring is sleeved on the arc surface of the installation rod. The two ends of the spring are fixedly connected to the adjusting block and the connecting frame, respectively. An adjusting plate is fixedly connected to the side of the adjusting block away from the tire forming machine body.

[0016] The effect achieved by the above-mentioned components is that when personnel need to use the operating roller to make tires, they can first move the adjusting plate to bring it as close as possible to the operating roller. Then, personnel can move several tire beads to fit them onto the surfaces of the auxiliary plate and the adjusting plate, which makes it easier for personnel to use the tire beads during subsequent tire making and improves the ease of operation.

[0017] Preferably, an anti-slip pad is fixedly connected to the side of the auxiliary plate away from the adjustment plate.

[0018] The effect achieved by the above components is that the anti-slip mat can increase the friction between the auxiliary plate and the tire bead, and can prevent the tire bead from slipping off the surface of the auxiliary plate during operation.

[0019] Preferably, a stop block is fixedly connected to the inner wall of the connecting frame.

[0020] The effect achieved by the above components is that the stop block can limit the adjustment block and prevent the spring from causing the adjustment block to rebound excessively.

[0021] Compared with related technologies, the anti-deviation guide structure for the pressure roller of a tire forming machine provided by this utility model has the following beneficial effects:

[0022] By setting a limiting structure, when personnel need to move the pressure roller body to press the tire on the operating roller, the limiting structure can guide and limit the pressure roller body, which can prevent the pressure roller body from deviating during the movement process and improve the stability of the pressure roller body during the movement process.

[0023] By setting up an auxiliary structure, when personnel need to use the operating roller to make tires, several tire beads can be pre-positioned through the auxiliary structure, which makes it convenient for personnel to use the tire beads later when making tires, thus improving the ease of operation for personnel.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figure 1This utility model provides a tire forming machine pressure roller anti-deviation guide structure, including: a base plate 5 and a limiting structure 3. The upper surface of the base plate 5 is equipped with a tire forming machine body 1 and two positioning devices 8. A control device 7 is installed on one side of the tire forming machine body 1. An operating roller 2 is installed inside the tire forming machine body 1. The arc surface of the operating roller 2 is provided with a plurality of tire bead 6. The upper surface of the base plate 5 is equipped with a pressure roller body 9 by means of the limiting structure 3. The upper surface of the base plate 5 is provided with the limiting structure 3. An auxiliary structure 4 is provided on the side of the tire forming machine body 1 near the operating roller 2.

[0032] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The limiting structure 3 includes two fixing plates 301 and a fixing block 302. The two fixing plates 301 are fixedly connected to the base plate 5, and the fixing block 302 is fixedly connected to the base plate 5. A limiting groove 303 is formed on the inner wall of the fixing plate 301. A connecting block 305 is slidably connected to the inner wall of the limiting groove 303. A connecting block 317 is fixedly connected to the side of the two connecting blocks 305 that is close to each other. The two connecting blocks 317 are rotatably connected to the pressure roller body 9. An auxiliary rod 316 is fixedly connected to the inner wall of the fixing block 302. A connecting plate 308 is rotatably connected to the arc surface of the auxiliary rod 316. A connecting rod 309 is rotatably connected to the inner wall of the connecting plate 308. The arc surface of the connecting rod 309 is rotatably connected to... There is a connecting plate 311, and the two ends of the connecting rod 309 are fixedly connected to the fixing frame 310. The two fixing plates 301 are fixedly connected to the mounting plate 315 on the side away from the fixing frame 310. The mounting plate 315 is fixedly connected to the cylinder 314 on the side away from the fixing frame 310. The arc surface of the output end of the cylinder 314 is slidably connected to the mounting plate 315. The output end of the cylinder 314 is fixedly connected to the fixing frame 310. The two connecting blocks 317 are fixedly connected to the moving plate 307 on the side close to each other. The lower surface of the moving plate 307 is fixedly connected to the positioning block 312. The inner wall of the positioning block 312 is fixedly connected to the fixing rod 313. The fixing rod 313 is rotatably connected to the connecting plate 311. When personnel need to press the tire on the operating roller 2, they can activate the cylinder 314 to move the fixed frame 310 closer to the mounting plate 315 until the pressure roller body 9 abuts against the tire on the operating roller 2. Then, the personnel can activate the operating roller 2 to press the tire on the operating roller 2. This prevents the pressure roller body 9 from shifting during movement, improving the stability of the pressure roller body 9 during movement. The inner wall of the limiting groove 303 is fixedly connected to a limiting rod 304, which is slidably connected to the connecting block 305. The limiting rod 304 can limit the connecting block 305, preventing the connecting block 305 from misaligning during sliding on the inner wall of the limiting groove 303. A protective pad 306 is fixedly connected to the upper surface of the connecting block 305, which is slidably connected to the limiting groove 303. The protective pad 306 protects the connecting block 305, preventing the upper surface of the connecting block 305 from directly contacting the top wall of the limiting groove 303. The moving plate 307 is made of stainless steel and has a rectangular cross-section. Stainless steel has high strength and good wear resistance, preventing deformation of the moving plate 307 during short-term use.

[0033] In the embodiments of this utility model, please refer to Figure 4The auxiliary structure 4 includes an auxiliary plate 41 and a connecting frame 43. The auxiliary plate 41 is fixedly connected to the tire forming machine body 1, and the connecting frame 43 is also fixedly connected to the tire forming machine body 1. An installation rod 44 is fixedly connected to the inner wall of the connecting frame 43. An adjusting block 45 is slidably connected to the arc surface of the installation rod 44, and a spring 47 is sleeved on the arc surface of the installation rod 44. The two ends of the spring 47 are fixedly connected to the adjusting block 45 and the connecting frame 43, respectively. An adjusting plate 46 is fixedly connected to the side of the adjusting block 45 away from the tire forming machine body 1. This allows the operator to move the adjusting plate 46 to be as close as possible to the operating roller 2 when using the operating roller 2 to make tires. Then, the operator moves several tire bead 6 to fit the surfaces of the auxiliary plate 41 and the adjusting plate 46, making it easier for the operator to use the tire bead 6 during tire making and improving the ease of operation. An anti-slip mat 42 is fixedly connected to the side of the auxiliary plate 41 away from the adjusting plate 46. The anti-slip mat 42 increases the friction between the auxiliary plate 41 and the tire bead 6, preventing the tire bead 6 from slipping off the surface of the auxiliary plate 41 during operation. A stop block 48 is fixedly connected to the inner wall of the connecting frame 43. The stop block 48 limits the adjustment block 45, preventing the spring 47 from excessively rebounding the adjustment block 45.

[0034] The working principle of the anti-deviation guide structure for the pressure roller of the tire forming machine provided by this utility model is as follows: When the operator needs to press the tire on the operating roller 2 through the pressure roller body 9, the operator can first start the cylinder 314. The output end of the cylinder 314 drives the fixed frame 310 to move closer to the mounting plate 315. The fixed frame 310 drives the connecting rod 309 to move closer to the mounting plate 315. The connecting rod 309 drives the connecting plate 308 and one end of the connecting plate 311 to move closer to the mounting plate 315. At this time, the connecting plate 311 rotates on the arc surface of the fixed rod 313, and the connecting plate 308 rotates on the arc surface of the auxiliary rod 316. Then, the connecting plate 311 drives the fixed rod 313 to move upward. The fixed rod 313 drives the positioning block 312 to move upward. The positioning block 312 drives the moving plate 307 to move upward. 07 drives two connecting blocks 317 to move upward, which in turn drives the pressure roller body 9 to move upward. The connecting blocks 317 also drive the connecting block 305 to move upward. The moving plate 307 is made of stainless steel, which has high strength and good wear resistance, preventing deformation of the moving plate 307 during short-term use. Then, the connecting block 305 drives the protective pad 306 to move upward. The protective pad 306 protects the connecting block 305 and prevents the upper surface of the connecting block 305 from directly contacting the top wall of the limiting groove 303. Then, the connecting block 305 slides on the arc surface of the limiting rod 304. The limiting rod 304 limits the connecting block 305 and prevents it from misaligning during sliding on the inner wall of the limiting groove 303, until the pressure roller body 9 abuts against the tire on the operating roller 2.

[0035] Additionally, when personnel need to use the operating roller 2 to make tires, they can first move the adjusting plate 46 closer to the operating roller 2. The adjusting plate 46 drives the adjusting block 45 away from the stop block 48, where the stop block 48 limits the adjusting block 45 to prevent the spring 47 from excessively rebounding. Then, the adjusting block 45 also stretches the spring 47 until the adjusting plate 46 moves to the appropriate position. Then, the personnel move several tire bead 6 closer to the operating roller. As the cylinder 2 moves, the tire bead 6 will first pass over the surface of the operating roller 2 until several tire bead 6 are fitted onto the surfaces of the anti-slip pad 42 and the adjusting plate 46. At this point, the operator releases the adjusting plate 46, and the spring 47 rebounds, causing the adjusting plate 46 to move away from the operating roller 2 until several tire bead 6 come into contact with the anti-slip pad 42 and the adjusting plate 46. The anti-slip pad 42 can increase the friction between the auxiliary plate 41 and the tire bead 6, preventing the tire bead 6 from slipping off the surface of the auxiliary plate 41 during operation.

[0036] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
