Description

Technical Field

[0001] The present invention belongs to the technical field of tire processing, and specifically relates to a zero-degree belt layer laminating tension adjusting mechanism. Background Art

[0002] An important process in the production process of radial tires is the forming process. This process mainly involves components such as the tire sidewall, inner liner, steel wire bead wrapper, cushion rubber, bead, belt layer, and tread that meet the design size standards. According to the positioning requirements, through actions such as laminating, transfer locking ring, inflation shaping, and pressing, the tire blank is precisely and symmetrically tightly combined into a vulcanizable tire blank. When the semi-components are laminated, appropriate tension must be ensured to guarantee the centering accuracy of feeding and laminating during the forming process and the uniform size and stress distribution of the internal materials of the finished tire. At present, the belt layer structure of domestic all-steel radial tires is mainly a 3+0 structure (three belt layers plus two zero-degree belts) and a four-belt layer structure.

[0003] During the lamination process of the zero-degree belt layer, there is a lack of a tension adjustment mechanism for the zero-degree belt layer. An overly loose zero-degree belt layer has a small adhesion force on the tire, affecting the quality of the final product. Therefore, it is necessary to design a zero-degree belt layer laminating tension adjusting mechanism. Summary of the Invention

[0007] The connecting shell is provided with balls, and the balls are in contact with the inner surface of the bracket. Through the design of the balls, the friction between the connecting shell and the bracket can be reduced.

[0008] The retractable movable mechanism includes a forward and reverse threaded shaft, a knob, a movable block, a guide block, a support plate, a sliding post, a universal wheel, a retaining ring, and a first spring. The forward and reverse threaded shaft is installed in the base through a bearing, the forward and reverse threaded shaft is fixedly connected to the knob, the outer portion of the forward and reverse threaded shaft is connected to two symmetrically distributed movable blocks through threads, the movable blocks are in contact with the inner surface of the base, the inner side of the base is fixedly connected to the support plate, the support plate is slidably connected to four evenly distributed sliding posts, the bottom of each sliding post is provided with a universal wheel, the sliding post is fixedly connected to the retaining ring, and the outer portion of the sliding post is provided with a first spring. When the knob is turned, the forward and reverse threaded shaft is rotated, and the threaded movement between the movable block and the forward and reverse threaded shaft can produce lateral displacement. The movable block can then apply downward pressure to the sliding post, causing the universal wheel at the bottom of the sliding post to contact the ground. This makes the whole body mobile and convenient for changing the use site or workshop. In addition, the forward and reverse threaded shaft can reset the universal wheel upward, so that the base supports the whole body and maintains stability.

The inner side of the connecting shell is fixedly connected to the fixed shaft, the outer side of the fixed shaft is slidably connected to the guide roller and the side plate, the side plate is fixedly connected to the guide roller, and both the side plate and the guide roller are in contact with the zero-degree belt layer. The inner side plate is connected to a bidirectional screw by a thread, and the bidirectional screw is fixedly connected to an I-shaped knob. The inner side of the connecting shell is fixedly connected to a limit pin, and the limit pin is slidably connected to the I-shaped knob. The bidirectional screw can be driven to rotate by the I-shaped knob, and the bidirectional screw moves the side plate and the guide roller through the threaded movement between the side plate, so that the distance between the guide rollers can be adjusted to meet the tension adjustment requirements of zero-degree belt layers of different widths, thereby increasing applicability.

One end of the third spring is fixedly connected to the stop block, and the other end of the third spring is fixedly connected to the turntable. Pull the pull ring upward, the pull ring drives the positioning pin to move upward, the positioning pin compresses the third spring through the stop block, and the positioning pin disengages from the current hole in the bracket, thereby releasing the restriction on the turntable.

[0014] The beneficial effects of the present invention are as follows: The present invention relates to a zero-degree belt layer laminating tension adjustment mechanism, which has the characteristics of multi-model zero-degree belt layer tension adjustment and high flexibility. In specific use, compared with the prior art, it has the following two beneficial effects:

The guide rollers and side plates in the adjusting mechanism are in direct contact with the zero-degree belt layer. In this way, the displacement generated by the threaded movement between the threaded sleeve and the threaded rod can apply a downward pressure to the zero-degree belt layer, so that the zero-degree belt layer can ensure sufficient tension during transmission. In addition, the adjusting mechanism can adjust the distance between the guide rollers, so as to meet the tension adjustment of zero-degree belt layers of different widths and increase applicability;

[0016] Second, by providing a retractable moving mechanism within the base, the retractable moving mechanism includes components such as a left-right threaded shaft, a turning knob, a moving block, a guiding block, a support plate, a sliding column, a universal wheel, a retaining ring and a first spring. The threaded movement between the moving block and the left-right threaded shaft can generate a lateral displacement. Subsequently, the moving block can apply a downward pressure to the sliding column, so that the universal wheel at the bottom of the sliding column abuts against the ground, so that the whole has mobility, which is convenient for changing the use site or workshop. In addition, reversing the left-right threaded shaft can reset the universal wheel upward, so that the base supports the whole and maintains stability. Description of the Drawings

[0028] Wherein, balls 10 are arranged on the connecting shell 8, and the balls 10 are in contact with the inner surface of the bracket 3. Through the design of the balls 10, the friction between the connecting shell 8 and the bracket 3 can be reduced.

[0029] Among them, the retractable moving mechanism 2 includes a left - right threaded shaft 21, a turning knob 22, moving blocks 23, guide blocks 24, a support plate 25, sliding columns 26, universal wheels 27, retaining rings 28 and first springs 29. The left - right threaded shaft 21 is installed in the base 1 through bearings. The turning knob 22 is fixedly connected to the left - right threaded shaft 21. Two symmetrically distributed moving blocks 23 are threadedly connected to the outside of the left - right threaded shaft 21. The moving blocks 23 are in contact with the inner surface of the base 1.

A first spring 29 is arranged outside the sliding column 26. When the turning knob 22 is rotated, the turning knob 22 drives the left - right threaded shaft 21 to rotate. The threaded movement between the moving blocks 23 and the left - right threaded shaft 21 can generate a lateral displacement. Subsequently, the moving blocks 23 can apply a downward pressure to the sliding columns 26, so that the universal wheels 27 at the bottom of the sliding columns 26 are in contact with the ground, making the whole unit mobile, which is convenient for changing the use site or workshop. In addition, reversing the left - right threaded shaft 21 can reset the universal wheels 27 upward, enabling the base 1 to support the whole unit and maintain stability.

By rotating the I - shaped knob 97, the bidirectional screw 96 can be driven to rotate. The bidirectional screw 96 makes the side plates 93 and the guide rollers 92 move through the threaded movement with the side plates 93, so as to adjust the distance between the guide rollers 92, meet the tension adjustment of the zero - degree belt layer 11 with different widths, and increase the applicability.

[0033] Among them, a transition rod 94 is slidingly connected inside the guide roller 92, and a second spring 95 is provided inside the guide roller 92. One end of the second spring 95 is fixedly connected to the transition rod 94, and the other end of the second spring 95 is fixedly connected to the inner surface of the guide roller 92. The design of the transition rod 94 facilitates the linkage between the guide rollers 92.

[0034] The locking mechanism 12 includes a positioning pin 121, a stopper 122, a pull ring 123, and a third spring 124. The positioning pin 121 is slidably connected to the inside of the turntable 5. One end of the positioning pin 121 is slidably connected to the bracket 3. The other end of the positioning pin 121 is fixedly connected to the pull ring 123.

One end of the third spring 124 is fixedly connected to the stopper 122, and the other end of the third spring 124 is fixedly connected to the turntable 5. When the pull ring 123 is pulled upward, the pull ring 123 drives the positioning pin 121 to move upward. The positioning pin 121 compresses the third spring 124 through the stopper 122, and the positioning pin 121 moves out of the current hole in the bracket 3, thereby releasing the restriction on the turntable 5.

[0035] The usage state of the present invention is as follows: when in use, the zero-degree belt layer 11 is unwound from the winding roller, and then adheres to the surface of the guide roller 92 and is located between the side plates 93, and then is wound around the tire auxiliary drum after passing through the cloud belt. If it is necessary to adjust the tension of the zero-degree belt layer 11 when unwinding, first pull the pull ring 123 upwards, and the pull ring 123 drives the positioning pin 121 to move upwards, and the positioning pin 121 compresses the third spring 124 through the block 122, and the positioning pin 121 leaves the current hole on the bracket 3, thereby releasing the restriction on the turntable 5, and then drives the turntable 5 to rotate through the rotating rod 6, and the turntable 5 drives the threaded sleeve 4 to rotate, and the threaded sleeve 4 passes between it and the threaded rod 7 The threaded movement causes the threaded rod 7 to produce a vertical displacement, and then the threaded rod 7 drives the connecting shell 8 to move downward, and the connecting shell 8 drives the adjusting mechanism 9 to move downward, and the guide roller 92 and the side plate 93 in the adjusting mechanism 9 can apply a downward pressure to the zero-degree belt layer 11, so that the zero-degree belt layer 11 can ensure sufficient tension during transportation. In addition, the bidirectional screw 96 can be driven to rotate by the I-shaped knob 97, and the bidirectional screw 96 moves the side plate 93 and the guide roller 92 through the threaded movement between the bidirectional screw 96 and the side plate 93, so that the distance between the guide rollers 92 can be adjusted to meet the tension adjustment of the zero-degree belt layer 11 of different widths, thereby increasing applicability;

[0036] Moreover, if it is necessary to change the overall usage location or workshop, simply rotate the knob 22. The knob 22 drives the rotation of the left - and - right - hand threaded shaft 21. The threaded movement between the moving block 23 and the left - and - right - hand threaded shaft 21 can generate a lateral displacement. Subsequently, the moving block 23 can exert a downward pressure on the sliding column 26, so that the universal wheel 27 at the bottom of the sliding column 26 touches the ground, making the whole unit mobile and facilitating the change of the usage site or workshop. In addition, reversing the rotation of the left - and - right - hand threaded shaft 21 can reset the universal wheel 27 upward, enabling the base 1 to support the whole unit and maintain stability.
