Description

Technical Field

[0001] The utility model relates to the technical field of tire production, and specifically relates to a device for improving the surface flatness of a tire self-sealing glue. Background Art

[0002] At present, there is a new type of tire structure called a self-sealing glue tire. Its function is that after the tire is punctured by a nail, the self-sealing glue inside the tire can prevent air leakage and self-repair.

[0003] In the production of self-sealing tires, a layer of highly viscous self-sealing glue is coated on the inner wall of the tire. Due to the viscosity, elasticity and expansibility of the self-sealing glue, when the self-sealing glue is coated on the inner wall, there is sometimes a slight unevenness on the surface, which affects the aesthetics. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for improving the surface flatness of a tire self-sealing glue, so as to solve the problems put forward in the above background art.

[0005] The technical solution of the utility model is: a device for improving the surface flatness of a tire self-sealing glue, including a base. A gantry support frame is fixed at the top of the base. A bidirectional drive assembly is installed at the top of the gantry support frame. A retaining rod is fixed at the bottom of the two moving ends of the bidirectional drive assembly. A power roller is rotatably installed on one side of the top of the base. One side of the end shaft of the power roller is connected to a drive mechanism installed at the bottom of the base. A rotary centering mechanism is rotatably installed on one side of the top of the base away from the power roller.

[0006] The effects achieved by the above components are as follows: The power roller and the rotary centering mechanism can support the two sides of the bottom end of the tire. Then, the bidirectional drive assembly drives the two retaining rods to block the two sides of the top end of the tire. Then, the drive mechanism drives the power roller to rotate, and further drives the tire to rotate, so that the self-sealing glue is evenly coated on the inner side of the tire. During the rotation of the tire, the rotary centering mechanism is driven to rotate synchronously, so that the tire is centered, ensuring that the tire can operate on the center line of the equipment to avoid deviation and improving the flatness of the glue coating.

[0007] Preferably, the rotary centering mechanism includes a rotating shaft rotatably arranged on the base, and a V-shaped centering wheel is fixed on the rotating shaft.

[0008] The effects achieved by the above components are as follows: The V-shaped centering wheel can assist in transmission and keep the tire centered at the same time. The V-shaped centering wheel rotates passively. When the tire is not in the middle position of the V-shaped centering wheel, the linear velocities of the tire and the V-shaped centering wheel are inconsistent when they are in contact, and the tire and the V-shaped centering wheel slide relative to each other, and the tire automatically moves to the middle position of the V-shaped centering wheel, forming an automatic positioning function.

[0009] Preferably, the bidirectional drive assembly includes a forward and reverse motor fixed on the top of the portal support frame, the output shaft of the forward and reverse motor is fixed with a bidirectional screw rod, both ends of the bidirectional screw rod are threaded with sliding sleeves, a guide block is fixed on one side of the sliding sleeve, a guide rail slidingly matched with the guide block is fixed on the top of the portal support frame, and the top of the gear rod is fixedly connected to the bottom of the guide block.

[0010] The effect achieved by the above components is: the forward and reverse motors can drive the bidirectional lead screw to rotate and cooperate with the guiding function of the guide rail and the guide block to drive the two sleeves to move closer to each other, and then drive the two gear rods to move closer synchronously.

[0011] Preferably, the driving mechanism comprises a driving motor fixed to the bottom of the base, and a pulley assembly is transmission-connected between the output shaft of the driving motor and the end shaft of the power roller.

[0012] The effect achieved by the above components is that the driving motor can cooperate with the pulley assembly to drive the power roller.

[0013] Preferably, a scanning device for scanning tire label information is installed on one side of the bottom end of the portal support frame.

[0014] The effect achieved by the above components is that the label information on the outer side of the tire can be identified by the code scanning device during the initial slow rotation of the tire.

[0015] Preferably, a touch screen is fixed to one side of the top end of the portal support frame.

[0016] The effect achieved by the above components is that the device can be controlled by cooperating with the control module through the touch screen.

[0017] The utility model provides a device for improving the surface flatness of tire self-sealing adhesive through improvement, which has the following improvements and advantages compared with the prior art:

[0018] The utility model can support the two sides of the bottom end of the tire through a power roller and a rotating centering mechanism, and then use a two-way driving component to drive two gear rods to stop the two sides of the top end of the tire. The driving mechanism then drives the power roller to rotate, and then drives the tire to rotate, so that the self-sealing glue is evenly coated on the inside of the tire. The tire drives the rotating centering mechanism to rotate synchronously during the rotation process, so that the tire is centered, ensuring that the tire can run on the center line of the equipment to avoid deviation, thereby improving the smoothness of the colloid coating.

The driving mechanism 5 includes a driving motor fixed at the bottom of the base 1, and a pulley assembly is connected between the output shaft of the driving motor and the end shaft of the power roller 4. The driving motor can cooperate with the pulley assembly to drive the power roller 4.

The rotating centering mechanism 3 includes a rotating shaft 31 rotatably set on the base 1, and a V-shaped centering wheel 32 is fixed on the rotating shaft 31. The V-shaped centering wheel 32 can assist the transmission and keep the tire centered at the same time. The V-shaped centering wheel 32 rotates passively. When the tire is not in the middle position of the V-shaped centering wheel 32, the linear speed of the tire when in contact with the V-shaped centering wheel 32 is inconsistent, and the tire and the V-shaped centering wheel 32 slide relative to each other, and the tire automatically moves to the middle position of the V-shaped centering wheel 32 to form an automatic positioning function.

[0029] In an embodiment of the utility model, a scanning device for scanning tire label information is installed on one side of the bottom end of the portal support frame 2.
