Description

Technical Field

[0001] The utility model relates to the technical field of tire tread rubber laminating and deviation correction, in particular to a tire tread rubber laminating and deviation correction device. Background Art

[0002] Tire retreading is the process of grinding away the part of the tire surface with a flat pattern with a tool to obtain a surface with a certain roughness, and then gluing a new rubber bond to make the old tire a complete tire. The process is generally to first grind the crown of the old tire to the optimal size, then adhere the tread rubber formed by high pressure to the surface of the carcass of the grinded old tire, and then vulcanize and bond them into one.

[0003] When the tread rubber is attached to the carcass surface, it must be aligned with the carcass surface. If it deviates, it will not only affect the appearance of the retreaded tire, but also make the tread rubber mass unevenly distributed, thereby affecting the balance of the tire and increasing the probability of serious blowout accidents during high-speed operation of the retreaded tire. At present, when attaching the tread rubber, it is generally manually observed whether it is aligned with the carcass surface, which is labor-intensive and difficult to completely correct the deviation. Therefore, those skilled in the art provide a tire tread rubber attachment correction device to solve the problems raised in the above background technology. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a tire tread rubber laminating and correcting device to solve the problem of manual observation of whether the tire body surface is aligned when laminating the tread rubber, which is labor-consuming.

[0008] Preferably, the lower two sides of the pressing block are inclined, and the inclined surface of the pressing block is in contact with the roller. Since the two sides of the bottom of the pressing block are inclined surfaces, when it contacts the roller, the V-shaped rod and the bracket are rotationally limited, and after the roller is squeezed, the deviation correction guide wheel connected to the upper end of the V-shaped rod is rotated and fits with the shoulders on both sides of the tire.

[0009] Preferably, the deviation-correcting guide wheel is tapered to facilitate fitting with the shoulder of the tire.

[0010] Preferably, the fixed shaft is slidably plugged into the fixed seat, one end of the extrusion spring is in extrusion contact with the pressure block, and the other end of the extrusion spring is in extrusion contact with the fixed seat, a limiting shaft is provided on the circumferential side of the extrusion spring, the limiting shaft is fixedly connected to the bottom of the pressure block, the limiting shaft is slidably plugged into the fixed seat, and after the tire completes the tread rubber bonding, it rises driven by the tire rotation mechanism, and the pressure block returns to its initial height under the action of the extrusion spring.

[0011] Preferably, a threaded hole is provided at the top end of the support shaft, and a nut is threadedly connected to the upper end of the support shaft through the threaded hole. The correction guide wheel rotatably sleeved on the support shaft can be replaced by unscrewing the nut, so that the correction device can correct tires of different specifications.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides a tire tread adhesive correction device, which has the following beneficial effects:

[0014] By design, after the tire is transported by the tire rotating mechanism to contact the pressure block, the pressure block continues to move downward due to the compression of the tire. During the downward movement of the pressure block, since the two sides of the bottom side of the pressure block are inclined surfaces, when it contacts the roller, the V-shaped rod and the bracket are rotationally limited. After the roller is squeezed, the deviation correction guide wheel connected to the upper end of the V-shaped rod is fitted with the shoulders on both sides of the tire, thereby limiting the two sides of the tread rubber when the tire tread rubber is fitted, avoiding the problem of deflection when the tread rubber is fitted, and the mechanism does not need to be manually observed whether it is aligned with the tire body surface.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides a technical solution, a tire tread rubber laminating and correcting device, please refer to Figure 1 , Figure 3 , comprising a fixed seat 1, brackets 2 are installed at both ends of the upper side of the fixed seat 1, a V-shaped rod 7 is rotatably clamped on the bracket 2, a roller 8 is rotatably connected to the bottom end of the V-shaped rod 7, a support shaft 9 is installed on the upper end of the V-shaped rod 7, a deviation correction guide wheel 11 is rotatably sleeved on the support shaft 9, a pressure block 3 is arranged on one side of the V-shaped rod 7, a fixed shaft 4 is installed at the bottom of the pressure block 3, and an extrusion spring 5 is sleeved on the circumference of the fixed shaft 4;

[0021] See also Figure 2 , Figure 3 The lower sides of the pressing block 3 are inclined, and the inclined surface of the pressing block 3 is in contact with the roller 8. Since the bottom sides of the pressing block 3 are inclined, when in contact with the roller 8, the V-shaped rod 7 and the bracket 2 are rotated and limited, and the roller 8 is squeezed so that the correction guide wheel 11 connected to the upper end of the V-shaped rod 7 is fitted with the shoulders of the tire. The correction guide wheel 11 is conical, which is convenient for fitting with the shoulders of the tire.

[0022] See also Figure 1 , Figure 3 The fixed shaft 4 is slidably plugged into the fixed seat 1, one end of the extrusion spring 5 is in extrusion contact with the pressure block 3, and the other end of the extrusion spring 5 is in extrusion contact with the fixed seat 1. A limiting shaft 6 is arranged on the circumferential side of the extrusion spring 5, and the limiting shaft 6 is fixedly connected to the bottom of the pressure block 3. The limiting shaft 6 is slidably plugged into the fixed seat 1. After the tire completes the tread rubber bonding, it rises under the drive of the tire rotation mechanism, and the pressure block 3 restores its initial height under the action of the extrusion spring 5. A threaded hole is provided at the top of the support shaft 9, and a nut 10 is threadedly connected to the upper end of the support shaft 9 through the threaded hole. The correction guide wheel 11 rotatably sleeved on the support shaft 9 can be replaced by unscrewing the nut 10, so that the correction device can correct tires of different specifications.

[0023] The tire tread rubber laminating and correcting device in the utility model is arranged below the tire rotating mechanism. After the tire is transported by the tire rotating mechanism to contact with the pressing block 3, the pressing block 3 is squeezed by the tire and continues to move downward. During the downward movement of the pressing block 3, since the two sides of the bottom of the pressing block 3 are inclined surfaces, when the pressing block 3 contacts with the roller 8, the V-shaped rod 7 and the bracket 2 are rotated and limited. After the roller 8 is squeezed, the correcting guide wheel 11 connected to the upper end of the V-shaped rod 7 is rotated and fitted with the two side shoulders of the tire, thereby limiting the two sides of the tread rubber when laminating the tire tread rubber, avoiding the problem of deflection when laminating the tread rubber, and the mechanism does not need to be manually observed whether the tire body surface is aligned;

[0024] After the tire has completed the tread rubber bonding, it is raised under the drive of the tire rotating mechanism, and the pressure block 3 is restored to its initial height under the action of the extrusion spring 5. Since the lower end of the V-shaped rod 7 is heavier than the upper end, after the pressure block 3 is raised, the upper ends of the two V-shaped rods 7 are simultaneously away from the tire, waiting for the next tire to be corrected;

[0025] And according to the different specifications of the tire, the correction guide wheel 11 rotatably sleeved on the support shaft 9 can be replaced by unscrewing the nut 10, so that the correction device can correct the tires of different specifications, thereby improving practicality.
