Description

Technical Field

[0001] The utility model relates to the technical field of tire manufacturing, and particularly relates to a cushion rubber exhaust device. Background Art

[0002] During the tire manufacturing process, cushion rubber is mainly used to enhance the adhesion between the tire tread and the carcass, ensuring that the tread rubber is firmly adhered to the polished carcass, thereby improving the overall structural strength of the tire. To prevent air bubbles from existing in the cushion rubber during production, an exhaust device is used to remove them. The method is to wrap the cushion rubber to be exhausted around a roller, and the exhaust devices are arranged oppositely. As the roller rotates, the exhaust devices apply pressure to squeeze the gas in the cushion rubber, causing it to be discharged from the exhaust line.

[0003] However, various uneven patterns are provided on the surface of the cushion rubber wrapped around the roller. This exhaust device can only exhaust the cushion rubber on the roller in a large area and cannot squeeze the small air bubbles between the patterns, resulting in poor exhaust effect and affecting the tire performance.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0026] According to an embodiment of the present utility model, a rubber padding exhaust device is provided. Please refer to Figures 1 to 3, including: a fixed shaft 1; a driving assembly 2, with multiple driving assemblies 2. The driving assembly 2 includes multiple piston rods 21, and the multiple piston rods 21 are respectively arranged at intervals along the length direction of the fixed shaft 1, and each piston rod 21 is arranged relative to the fixed shaft 1 in a telescopic manner; multiple retaining ring assemblies 3, with multiple retaining ring assemblies 3 sleeved on the fixed shaft 1, and the multiple retaining ring assemblies 3 are respectively arranged at intervals along the length direction of the fixed shaft 1. Each retaining ring assembly 3 is arranged in one-to-one correspondence with each piston rod 21. The retaining ring assembly 3 includes a retaining ring 31. When each piston rod 21 expands and contracts, it drives the retaining ring assembly 3 to move relative to the fixed shaft 1, so that each retaining ring 31 presses on the cushion rubber; a controller, which is connected to each driving assembly 2, and the controller is used to control the telescopic range of the piston rod 21, thereby adjusting the moving distance of each retaining ring 31. The multiple piston rods 21 are fixed on the fixed shaft 1. During use, first, according to the pattern of the cushion rubber (that is, different thicknesses), set the telescopic distance of each piston rod 21. This distance can push the retaining ring 31 to extend and just press on the cushion rubber. During the process of the roller driving the cushion rubber to rotate, one side of the cushion rubber is pressed by the retaining ring 31, so that the internal air bubbles are discharged from the exhaust line of the cushion rubber. The retaining ring 31 presses the cushion rubber along the direction perpendicular to the rotation axis. The narrower the width of the retaining ring 31 is set, the more it can squeeze the small air bubbles between the patterns. The controller is connected to each driving assembly 2, and can accurately control the telescopic range of each piston rod 21, thereby realizing the accurate adjustment of the moving distance of each retaining ring 31. The moving distance of the retaining ring 31 is equivalent to matching the thickness of the cushion rubber, and can be applied to the patterns with different thicknesses of the same roll of cushion rubber. This accurate control can ensure that the retaining ring 31 applies appropriate pressure to the cushion rubber at different positions, further improving the exhaust effect. The cushion rubber exhaust device of this embodiment solves the technical problem that the existing exhaust equipment in the related art cannot discharge the small air bubbles in the cushion rubber.

[0027] Refer to Figure 1 and Figure 2 , for the cushion rubber exhaust device of this embodiment, the retaining ring 31 is rotatably arranged relative to the retaining ring assembly 3, so that the retaining ring 31 reduces the friction with the cushion rubber during the pressing process. When the produced cushion rubber has not been exhausted, its surface has bristles and is relatively rough. The rotating retaining ring 31 can press the bristles on the cushion rubber to make it smooth. It should be noted that the smoothness here refers to the surface roughness of the cushion rubber, which is different from the pattern. If there are bristles, it will also make the pattern unclear.

[0028] Refer to Figure 1 and Figure 2 , for the cushion rubber exhaust device of this embodiment, the driving assembly 2 further includes multiple air pipes and multiple cylinders 22. Each air pipe is respectively connected to each cylinder 22, and the air pipe conveys compressed air to the cylinder 22 to drive the piston rod 21 to move. By conveying compressed air to the cylinder 22 through the air pipe, a stable and reliable power source is provided for the movement of the piston rod 21.

[0029] Refer to Figure 1 and Figure 2 For the rubber padding exhaust device of this embodiment, each piston rod 21 passes through the fixed shaft 1. The fixed shaft 1 is of a hollow structure. The air cylinder 22 is arranged inside the fixed shaft 1. A number of through holes 11 are provided on the fixed shaft 1. The air delivery pipe passes through the through holes 11 and is connected to the air cylinder 22. By placing the air cylinder 22 inside the fixed shaft 1, the structure of the whole device becomes more compact, saving space to the greatest extent.

[0030] Refer to Figure 1 and Figure 3 For the rubber padding exhaust device of this embodiment, each piston rod 21 is arranged in a staggered manner along the length direction of the fixed shaft 1, so as to increase the distance between the piston rods 21 and increase the number of pressing ring assemblies 3 on the fixed shaft 1, thereby reducing the width of each pressing ring 31 and reducing the contact surface between each pressing ring 31 and the rubber padding. The staggered arrangement not only avoids the direct collision and interference between the piston rods 21, but also can increase the number of pressing ring assemblies 3 and reduce the width of each pressing ring 31, enabling each pressing ring 31 to more precisely correspond to a small area when pressing. More pressing ring assemblies 3 mean that more pressing points can act on the rubber padding simultaneously, improving the overall exhaust efficiency.

[0031] Refer to Figure 1 and Figure 3 For the rubber padding exhaust device of this embodiment, the rubber padding exhaust device further includes a support base 4. Both ends of the fixed shaft 1 are connected to the support base 4. The pressing ring assembly 3 further includes an abutting frame 32. A receiving cavity 33 is provided on the abutting frame 32. The fixed shaft 1 passes through the receiving cavity 33 to support the abutting frame 32. The pressing ring 31 is sleeved on the abutting frame 32. The pressing ring 31 is rotatable relative to the abutting frame 32. The piston rod 21 expands and contracts in the receiving cavity 33, pushing the abutting frame 32 to move relative to the support base 4, thereby driving the pressing ring 31 to move. Both ends of the fixed shaft 1 are connected to the support base 4, providing a stable support foundation for the whole device. The piston rod 21 expands and contracts in the receiving cavity 33, pushing the abutting frame 32 to move relative to the support base 4. This design enables the pressing ring 31 to accurately move to the designated position to effectively compress and exhaust the rubber padding.

[0032] Refer to Figure 2, for the rubber padding exhaust device of this embodiment, an annular gap 34 is provided between the pressing ring 31 and the abutting frame 32. The pressing ring assembly 3 further includes a plurality of balls 35, and the plurality of balls 35 are arranged in the annular gap 34. When the pressing ring 31 rotates, the plurality of balls 35 roll between the pressing ring 31 and the abutting frame 32. When the pressing ring 31 rotates, the balls 35 roll in the annular gap 34 between the pressing ring 31 and the abutting frame 32. This rolling friction has a lower friction coefficient compared to the pressing ring 31 directly rotating on the abutting frame 32. Therefore, it can significantly reduce the friction and wear between the pressing ring 31 and the abutting frame 32, and extend the service life of the equipment.

[0033] Refer to Figure 1 , for the rubber padding exhaust device of this embodiment, there are multiple fixed shafts 1, and both ends of each fixed shaft 1 are fixed on the support seat 4. By increasing or decreasing the number of the fixed shafts 1 according to the width of the rubber padding, flexible adjustment of the movement track of the pressing ring assembly 3 can be achieved.

[0034] Refer to Figure 1 , for the rubber padding exhaust device of this embodiment, the rubber padding exhaust device further includes a press roller support 5 and a base 6. The support seat 4 is fixed on the press roller support 5, and the press roller support 5 is fixed on the base 6. A plurality of grooves 51 are provided on the press roller support 5, and each air delivery pipe is arranged in the groove 51. The orderly arrangement of the air delivery pipes in the grooves 51 not only reduces the interference and entanglement between the pipelines, but also makes the exhaust process smoother. This helps to improve work efficiency and reduce failures caused by pipeline chaos. The firm connection between the support seat 4, the press roller support 5 and the base 6 ensures the stability of the device during operation.

[0035] Refer to Figure 1 and Figure 3 , for the rubber padding exhaust device of this embodiment, the press roller support 5 is movably arranged relative to the base 6. Move the press roller support 5 to adjust the distance between the pressing ring 31 and the rubber padding. Since the press roller support 5 can be conveniently moved, the position of the pressing ring 31 can be quickly adjusted to adapt to different rubber padding thicknesses or exhaust requirements. The press roller support 5 and the base 6 can be provided with adjustment holes to adjust their connection positions; or a slider can be provided on the press roller support 5 and a chute can be provided on the base 6, and the slider moves in the chute to adjust the distance between the pressing ring 31 and the rubber padding. The adjustment structure includes but is not limited to the above structures.
