Description

Technical Field

[0001] This invention relates to the field of rubber tire production equipment technology, and in particular to a rubber tire tread forming and compaction device. Background Technology

[0002] In the rubber tire production process, the compaction process during tread forming is crucial, directly affecting the tire tread's density, smoothness, and subsequent adhesion to the tire carcass, thus determining the tire's overall performance and lifespan. Currently, many commonly used tire tread compaction devices suffer from insufficient compaction uniformity: some devices employ a single roller or flat plate compaction structure, only applying pressure to the entire tread, easily leading to uneven density in certain areas and subsequent issues such as uneven wear and bulges. Furthermore, traditional compaction devices lack sufficient linkage between the drive system and the compaction mechanism. When the clamping seat spacing is adjusted, the drive mechanism struggles to synchronize the transmission, easily resulting in transmission lag or disengagement, further reducing compaction stability and continuity. Additionally, some devices lack protective structures on the edges of the compaction blocks, easily scratching the tread surface during compaction, affecting the tire's appearance and quality. These problems restrict the efficiency and quality of the tire tread compaction process, necessitating a compaction device with a reasonable structure, uniform compaction, strong adaptability, and high stability to address these pain points.

The two connecting blocks 315 are positioned below... Rollers 314 are movably connected to the front and rear positions of the sides via pins. Rollers 314 reduce friction during movement and are movably connected to the inner sides of corresponding annular grooves 313, rolling along the trajectory of the annular grooves 313. The screw 317 is movably connected to the center of the slide groove 316 via a bearing, providing a transmission basis for the movement of the clamping seat 4. The right end of the screw 317 is fixedly connected to a driven gear 3111 via a flat key. The top of the slide 318 is fixedly welded to the center of the bottom of the clamping seat 4, cooperating with the connecting block 315 to achieve stable support for the clamping seat 4. The slide 318... The central part has a vertical guide groove 319, and a vertical nut block 3110 is movably connected inside the guide groove 319. The nut block 3110 can be vertically fine-tuned within the guide groove 319. The threaded hole in the center of the nut block 3110 is connected to the screw 317, which drives the slide 318 to move through the threaded transmission. The driving gear 3112 is movably connected to the right side of the center of the fixed seat 311 through a bearing. The driving gear 3112 meshes with the driven gear 3111 to realize power transmission.

The motor 334 is fixedly connected to the outside of the drive housing 331 by bolts for easy maintenance and repair. The output shaft of the motor 334 is fixedly connected to the center of the end of one of the drive shafts 336 through a coupling to provide a power source for the synchronous drive device 33. The motor 334 is a servo motor or a stepper motor, which can achieve precise speed and steering control to meet the compaction requirements of different tire tread specifications.

[0029] like Figure 6As shown, the compaction mechanism 5 includes a second drive shaft 51, an eccentric wheel 52, a short groove 53, a first connecting blind hole 54, a first tension spring 55, a second connecting blind hole 56, a short compaction block 57, a long compaction block 58, an eccentric roller 59, a third connecting blind hole 510, a second tension spring 511, a fourth connecting blind hole 512, and a long groove 513. The second drive shaft 51 is movably connected to the inside of the clamping seat 4 via bearings and is arranged along the length direction of the clamping seat 4. Several eccentric wheels 52 are fixedly connected to the left side of the second drive shaft 51 via flat keys. The number of eccentric wheels 52 is designed according to the tire tread width, and the eccentric directions of the eccentric wheels 52 are all different, which can realize the compaction of the tire. The left side of the surface is alternately compacted in different areas. An eccentric roller 59 is fixedly connected to the outside of the right side of the second drive shaft 51 via a flat key. The length of the eccentric roller 59 matches that of the long compaction block 58. The input end of the second drive shaft 51 is connected to the output end of the front side of the follow-up drive device 7 via a coupling. Several short grooves 53 are present, the number matching that of the eccentric wheels 52. These short grooves 53 are evenly distributed on the left side of the clamping seat 4, providing installation and movement space for the short compaction blocks 57. Each of the bottom sides of the short grooves 53 has a connecting blind hole 54 for connecting a tension spring 55. Several short compaction blocks 57 are connected to the short grooves... Each of the short compaction blocks 57 has a corresponding short groove 53 on its lower outer side, allowing it to move vertically along the groove 53. Each of the short compaction blocks 57 has a connecting blind hole 56 on both sides of its bottom, and each blind hole 56 is connected to a corresponding connecting blind hole 54 via a tension spring 55. The tension spring 55 provides a reset force for the short compaction block 57. The center of the bottom of each short compaction block 57 is connected to the upper side of a corresponding eccentric wheel 52 via a contact connection, allowing the eccentric wheel 52 to push the short compaction block 57 up and down. The long groove 513 is located on the right side of the clamping seat 4, its length covering the right side of the tire tread. The long groove 513 has connecting blind holes 512 on both sides of its bottom for connecting tension springs 511. The long compaction block 58 is vertically movably connected to the inside of the long groove 513 on its lower exterior and can move vertically along the long groove 513. The long compaction block 58 has connecting blind holes 510 on both sides of its bottom, and each connecting blind hole 510 is connected to the corresponding connecting blind hole 512 through tension springs 511. Tension springs 511 provide a reset tension for the long compaction block 58. The bottom of the long compaction block 58 is connected to the upper side of the eccentric roller 59 through a contact connection, and the eccentric roller 59 pushes the long compaction block 58 to move up and down.

[0030] The short compaction block 57 and the long compaction block 58 are both provided with rounded corners at their upper edges, with a rounded corner radius of 2-5mm, which can effectively prevent scratches on the tire tread surface during the compaction process and protect the appearance quality of the tire tread.

[0031] like Figure 7As shown, the follower drive device 7 includes a guide slot seat 71, a movable block 72, a follower block 73, a transmission mechanism 74, a vertical slot 75, a spline shaft 76, a second driving gear 77, a second motor 78, a second driven gear 79, and a movable seat 710.

A driven gear 79 is fixedly connected to the outside of the center of the spline shaft 76 via a flat key, and the driven gear 79 meshes with the driving gear 77 to realize power transmission. There are two follower blocks 73, corresponding to the upper and lower clamping seats 4. One side of the two follower blocks 73 is movably connected to the inside of the corresponding vertical groove 75, and can move vertically along the vertical groove 75. The other side of the two follower blocks 73 is fixedly connected to the right end of the corresponding clamping seat 4 via bolts, and moves synchronously with the clamping seat 4. Each of the two follower blocks 73 is provided with a transmission mechanism 74. One side of the transmission mechanism 74 is connected to the spline shaft 76 via a spline, ensuring that power can be transmitted to the transmission mechanism 74 when the spline shaft 76 rotates, while allowing the follower blocks 73 to move vertically. The other side of the transmission mechanism 74 is connected to the input end of the transmission shaft 51 of the compaction mechanism 5 via a coupling.

[0032] like Figure 8As shown, the transmission mechanism 74 includes a third transmission shaft 741, a first bevel gear 742, a second bevel gear 743, a fourth transmission shaft 744, a third bevel gear 745, and a fourth bevel gear 746, which change the direction of power transmission through bevel gear meshing. The third transmission shaft 741 is movably connected to the interior of the follower block 73 on the other side via a bearing and is arranged horizontally. One side of the third transmission shaft 741 is connected to the input end of the second transmission shaft 51 of the compaction mechanism 5 via a coupling, and the first bevel gear 742 is fixedly connected to the exterior of the other side of the third transmission shaft 741 via a flat key.

In the directional setting of 1, a bevel gear 745 is fixedly connected to one side of the drive shaft 744 via a flat key, and a bevel gear 743 is fixedly connected to the other side of the drive shaft 744 via a flat key. The bevel gear 743 meshes with the bevel gear 742, realizing a 90° change in the power direction. The bevel gear 746 is movably connected to the inside of the follower block 73 via a bearing. The spline hole in the center of the bevel gear 746 is connected to the spline shaft 76 via a spline, ensuring that the spline shaft 76 drives the bevel gear 746 to rotate synchronously. The bevel gear 746 meshes with the bevel gear 745, transmitting the power of the spline shaft 76 to the drive shaft 744.

[0033] The invention is used in the following way: It has a reasonable and simple structure, low production cost, convenient installation, and complete functions. In use, the rubber tire tread to be compacted first enters from the left side of the device. Guided by the input guide roller 6 (located inside the left opening of the compaction chamber 2), it smoothly enters the compaction chamber 2 inside the outer shell 1. At this time, the operator can start the device, first triggering the synchronous drive device 33 to start working: the motor 334 (servo motor or stepper motor) in the synchronous drive device 33 starts, and its output shaft drives a transmission shaft 336 fixedly connected to it to rotate. The pulley 335 outside the transmission shaft 336 rotates accordingly. Through the transmission action of the synchronous belt 333, it drives the transmission chamber 332 inside the drive housing 331. The other drive shaft 336 on the lower side rotates synchronously. The two drive shafts 336 are respectively connected to the input ends (i.e., the center of the drive gear 3112) of the lower moving device 31 and the upper moving device 32. Therefore, they will synchronously drive the drive gear 3112 in the lower moving device 31 and the upper moving device 32 to rotate. The drive gear 3112 meshes with the driven gear 3111, which in turn drives the screw 317 in the center of the slide groove 316 in the fixed seat 311 to rotate. The screw 317 is threadedly connected to the nut block 3110 in the guide groove 319 in the slide 318. As the screw 317 rotates, the nut block 3110 moves axially along the screw 317, driving the slide 318 and the clamping seat 4 fixed thereto to move. At the same time, the bottom of the clamping seat 4 moves left and right. The rollers 314 on the lower front and rear positions of the connecting blocks 315 on both sides will roll in the annular grooves 313 (left lower and right higher inclined) on the front and rear walls of the slide groove 312 of the fixed seat 311. Due to the inclined structure of the annular groove 313, the clamping seat 4 will adjust its position in the vertical direction while moving horizontally. Finally, the two clamping seats 4 will move closer to each other when moving to the right and move further apart when moving to the left. At the same time as the clamping seat 4 moves, the follow-up drive device 7 is started. The output shaft of its motor 78 (fixed in the center of the outer side of the movable seat 710) drives the drive gear 77 to rotate. The drive gear 77 meshes with the driven gear 79 on the outer side of the center of the spline shaft 76, thereby driving the spline shaft 76 (movably connected to the vertical groove 75 of the movable seat 710 on the upper and lower sides) to rotate. Since the follower block 73 is movably connected to the inside of the vertical groove 75 on one side and fixed to the right end of the clamping seat 4 on the other side, and the transmission mechanism 74 inside the follower block 73 is connected to the spline shaft 76 and the input end of the compaction mechanism 5, the rotation of the spline shaft 76 is transmitted to the compaction mechanism 5 through the transmission mechanism 74. In the transmission mechanism 74, the spline shaft 76 drives the connected bevel gear 4 746 to rotate. The bevel gear 4 746 meshes with the bevel gear 3 745, driving the transmission shaft 4 744 to rotate. The bevel gear 2 743 on the other side of the transmission shaft 4 744 meshes with the bevel gear 1 742 on the transmission shaft 3 741, ultimately causing the transmission shaft 3 741 to drive the transmission shaft 2 51 of the compaction mechanism 5 (movably connected inside the clamping seat 4) to rotate. When the transmission shaft 2 51 rotates,Several eccentric wheels 52 on the left side (each with a different eccentric direction) rotate synchronously. The upper side of the eccentric wheels 52 is connected to the center of the bottom of the short compaction block 57, which pushes the short compaction block 57 to move up and down reciprocally within the short groove 53 of the clamping seat 4. At the same time, the connecting blind holes 56 on both sides of the bottom of the short compaction block 57 are connected to the connecting blind holes 54 at the bottom of the short groove 53 through tension springs 55. Under the reset action of tension springs 55, the short compaction block 57 always remains in contact with the eccentric wheels 52, achieving intermittent compaction of different areas on the left side of the tire tread. Meanwhile, the eccentric roller 59 on the right side of the drive shaft 51 rotates synchronously. The upper side of the eccentric roller 59 is connected to the bottom of the long compaction block 58, which pushes the long compaction block 58 to move up and down reciprocally within the long groove 513 of the clamping seat 4. The connecting blind holes 510 on both sides of the bottom of the 58 are connected to the connecting blind holes 512 at the bottom of the long groove 513 via tension spring 511. Under the reset action of tension spring 511, the long compaction block 58 and the eccentric roller 59 remain in contact, continuously compacting the right side area of ​​the tire tread (because the eccentric roller 59 has a roller-like structure, the compaction process is more continuous). Furthermore, since the upper edges of both the short compaction block 57 and the long compaction block 58 are rounded, scratches on the tire tread can be avoided during compaction. During compaction, the tire tread gradually moves to the right under the action of the upper and lower compaction mechanisms 5, and is finally guided by the output guide rollers 8 at the upper and lower positions inside the right opening of the compaction chamber 2, completing the entire compaction process and being output from the right side of the device. Thus, the device completes one tire tread forming and compaction operation.
