Description

Technical Field

[0001] The utility model relates to the technical field of tire spraying equipment, in particular to a tread spraying device for tire production. Background Art

[0002] In today's society, with the rapid development of automobiles and the increasingly developed transportation network between towns, cars have become an indispensable means of transportation for every family. At the same time, the safety performance of cars has also attracted more and more attention. As one of the important parts of a car, the tire is in direct contact with the road surface, and together with the car suspension, it can alleviate the impact of the car when driving, ensure that the car has good riding comfort and driving smoothness; ensure that the wheels and the road surface have good adhesion; improve the traction, braking and passability of the car; bear the weight of the car, and the important role played by the tire on the car is increasingly valued by people. A new type of safety tire with a layer of nano-polymer memory rubber material attached to the inner wall of the tire has been introduced, which can completely solve the safety hazards caused by punctures and even blowouts of ordinary rubber tires. In order to maximize the effective area of ​​puncture protection of the safety tire, the edge R corner of the tire contacting the ground also needs to be treated with anti-puncture and anti-leakage.

[0003] In order to spray the nano polymer memory rubber material on the tire, a tire glue spraying machine spraying device is generally used to spray the tire. The tire glue spraying machine spraying device in the prior art includes a glue feeding device, a glue spraying device, a cooling device, a tire positioning device and a central control device. The glue melting furnace is made of aluminum alloy. After the colloid is heated into glue liquid by the glue melting furnace, it is transmitted to the glue spraying device through the glue feeding device to spray the tire on the tire positioning device. The previous fixed-point positioning, double-hole spraying device, and the coating method in which the rubber material is closed by the centrifugal force generated by the rotation speed of the tire are changed to realize single-hole linear spraying and secondary spraying, ensuring that the dynamic balance error on the left and right sides of the tire after spraying is within the allowable range, the spraying thickness of the rubber material at any point is uniform, and the sprayed surface is smooth and free of bubbles.

[0004] However, when the existing tire spraying device is spraying, the tire direction is fixed and cannot be sprayed at multiple angles, resulting in poor spraying effect. In order to achieve spraying at multiple angles, manual assistance is required to adjust the tire direction multiple times, which greatly increases labor consumption and reduces spraying efficiency. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the direction of the tire cannot be adjusted autonomously during spraying. The utility model provides a tread spraying device for tire production, which can adjust the direction of the tire so that the tire has a larger material surface during spraying, effectively improves the quality of spraying, and reduces the consumption of human resources.

[0006] In order to solve the above technical problems, the embodiment of the utility model discloses a tread spraying device for tire production, comprising:

[0007] Workbench;

[0008] a frame, the frame being supported on the workbench;

[0009] A driving part, comprising a first driving member and a second driving member, wherein the first driving member is connected to the frame;

[0010] a first rotating shaft connected to the first driving member, the first rotating shaft extending along a first direction, the first driving member being capable of driving the first rotating shaft to axially rotate 0 to 360 degrees around the first direction, the first rotating shaft being spaced apart from the workbench along a second direction, the second direction being perpendicular to the first direction;

[0011] A mounting portion, along the first direction, the mounting portion is arranged at an end of the first rotating shaft away from the first driving member;

[0012] a second rotating shaft, the second rotating shaft being connected to the mounting portion, the second rotating shaft extending along a third direction, the second driving member being disposed at one end of the second rotating shaft, the second driving member being capable of driving the second rotating shaft to axially rotate 0 to 180 degrees around the third direction, the third direction being perpendicular to the first direction;

[0013] A clamping portion connected to the second rotating shaft, wherein the clamping portion includes an arc-shaped portion, and the arc-shaped portion is used to support the inner tread of the tire;

[0014] The spraying part is connected with the frame and faces the clamping part, and the spraying part and the clamping part are spaced apart.

[0015] By adopting the above technical solution, a spraying structure can be established by setting a workbench and a frame, which is conducive to installing the tire for spraying and reducing the difficulty of manual operation. Before spraying, the operator first supports the inner tread of the tire through the arc portion of the clamping part to fix the tire so that the tire is perpendicular to the workbench. The spraying part faces the clamping part, that is, the spraying part faces the tire, and then the spraying material is sprayed through the spraying part to spray the tire.

[0016] During the spraying process, the operator starts the first driving member to drive the first rotating shaft to rotate 0 to 360 degrees around the first direction to spray the crown part of the tire. Since the first rotating shaft is connected to the second rotating shaft, the second rotating shaft is connected to the clamping part, and the clamping part supports the tire. Therefore, the first driving member can drive the first rotating shaft to drive the tire to rotate, so that the spraying part can spray the crown part of the tire 360 ​​degrees, that is, spray the entire crown part of the tire, which improves the quality of the spraying work and speeds up the spraying efficiency.

[0017] After the crown part of the tire is sprayed, the shoulder part of the tire needs to be sprayed. The second driving member can drive the second rotating shaft to rotate axially 0 to 180 degrees around the third direction, but in actual operation, the second rotating shaft only needs to rotate axially 0 to 90 degrees around the third direction to complete the spraying of the shoulder part of the tire. Therefore, the operator starts the second driving member to drive the second rotating shaft to rotate axially 0 to 90 degrees around the third direction. During the rotation process, the spray part sprays the shoulder part of the tire. In addition, a small amount of spraying can also be performed on the sidewall part of the tire.

[0018] Therefore, the operator can spray the entire crown of the tire at 360° by starting the first driving member to drive the first rotating shaft to axially rotate 0 to 360° around the first direction; and can spray the shoulder of the tire by starting the second driving member to drive the second rotating shaft to axially rotate 0 to 90° around the third direction, thereby adjusting the upper and lower directions of the tire to be sprayed. Thus, the sprayed surface is adjusted and expanded, so that the tire has a larger surface when spraying, effectively improving the quality of spraying and reducing the consumption of human resources.

[0020] By adopting the above technical solution, the first driving member can drive the first rotating shaft to drive the tire to rotate 360°. The second part and the third part are fixedly installed at both ends of the first part, so when the first driving member drives the first rotating shaft to drive the first part to rotate, the second part and the third part will follow the first part to rotate with the first rotating shaft as the axis, and the rotatable angle is also 360°.

[0021] According to another specific implementation of the present utility model, the first driving member is a first motor.

[0024] By adopting the above technical solution, the clamping part and the second rotating shaft can be connected through the first connecting part, and the entire clamping part can be fixedly connected to improve the stability of clamping the tire. The two ends of the bidirectional cylinder are respectively connected to the arc-shaped part, and the arc-shaped part fits the inner wall of the tire. The inner wall of the tire can be expanded and clamped by the bidirectional cylinder, which greatly improves the overall stability of the tread spraying device for tire production.

[0054] refer to Figure 2 and Figure 3 The driving part 3 includes a first driving member 31, a second driving member 32 and a motor box 33. The first driving member 31 is disposed in the motor box 33. The first driving member 31 is connected to the third supporting portion 212 of the frame 21 and moves along the first direction ( Figure 2 The first driving member 31 is disposed at one end of the third supporting portion 212 of the frame 21, and the first driving member 31 is spaced apart from the workbench 2.

[0055] refer to Figure 2 and Figure 3 The first rotating shaft 4 is disposed at the other end of the third supporting portion 212 of the frame 21. The first rotating shaft 4 is connected to the first driving member 31. The first rotating shaft 4 is rotated along the first direction ( Figure 3 The first driving member 31 can drive the first rotating shaft 4 to rotate 0 to 360 degrees axially around the first direction and extend in the second direction ( Figure 3 The first rotating shaft 4 is spaced apart from the workbench 2, and the second direction is perpendicular to the first direction.

[0056] Continue to refer Figure 2 and Figure 3 The tire tread spraying device 1 for tire production includes a mounting portion 8, along a first direction ( Figure 3 The mounting portion 8 is disposed at one end of the first rotating shaft 4 away from the first driving member 31. The second rotating shaft 5 is connected to the mounting portion 8. The second rotating shaft 5 is disposed along the third direction ( Figure 3 The second driving member 32 is disposed at one end of the second rotating shaft 5, and the second driving member 32 can drive the second rotating shaft 5 to rotate in the third direction ( Figure 3 The Z direction) is an axial rotation of 0 to 180°, and the third direction is perpendicular to the first direction ( Figure 3 X direction).

[0057] refer to Figure 2 , Figure 3 and Figure 4 The clamping portion 6 is connected to the second rotating shaft 5. The clamping portion 6 includes two arc-shaped portions 61. The arc-shaped portions 61 are used to support the inner surface of the tire (not shown in the figure). The spraying portion 7 faces the clamping portion 6 and moves along the second direction ( Figure 2 In the middle Y direction), the spraying part 7 and the clamping part 6 are arranged at intervals.

[0058] By adopting the above technical solution, by setting up the workbench 2 and the frame 21, a spraying structure can be established, which is conducive to installing the tire for spraying and reducing the difficulty of manual operation. Before spraying, the operator first supports the inner tread of the tire through the arc portion 61 of the clamping portion 6 to fix the tire so that the tire is perpendicular to the workbench 2. The spraying portion 7 is facing the clamping portion 6, that is, the spraying portion 7 is facing the tire, and then the spraying material is sprayed out by the spraying portion 7 to spray the tire. The tread spraying device 1 for tire production is supported on the ground by four first support portions 22, which can improve the overall stability of the tread spraying device 1 for tire production.

[0059] During the spraying process, the operator starts the first driving member 31 to drive the first rotating shaft 4 to rotate 0 to 360 degrees around the first direction to spray the crown part of the tire. Since the first rotating shaft 4 is connected to the second rotating shaft 5, the second rotating shaft 5 is connected to the clamping part 6, and the arc portion 61 of the clamping part 6 supports the tire, the first driving member 31 can drive the first rotating shaft 4 to drive the tire to rotate, so that the spraying part 7 can spray the crown part of the tire 360 ​​degrees, that is, spray the entire crown part of the tire. The quality of the spraying work is improved, and the spraying efficiency is accelerated.

[0060] After the crown part of the tire is sprayed, the shoulder part of the tire needs to be sprayed. The second driving member 32 can drive the second rotating shaft 5 to axially rotate 0 to 180 degrees around the third direction, but in actual operation, the second rotating shaft 5 only needs to axially rotate 0 to 90 degrees around the third direction to complete the spraying of the shoulder part of the tire. Therefore, the operator starts the second driving member 32 to drive the second rotating shaft 5 to axially rotate 0 to 90 degrees around the third direction. During the rotation process, the spray part 7 sprays the shoulder part of the tire. In addition, a small amount of spraying can also be performed on the sidewall part of the tire.

[0061] Therefore, the operator can start the first driving member 31 to drive the first rotating shaft 4 to axially rotate 0 to 360 degrees around the first direction, and can spray the entire crown part of the tire 360 ​​degrees; start the second driving member 32 to drive the second rotating shaft 5 to axially rotate 0 to 90 degrees around the third direction, so as to adjust the upper and lower directions of the tire to be sprayed, and can spray the shoulder part of the tire. In this way, the sprayed surface is adjusted and expanded, so that the tire has a larger material surface during spraying, effectively improving the quality of spraying and reducing the consumption of human resources.

[0062] By providing a motor box 33 on one side of the frame 21, it is possible to protect the rotating components and extend the service life of the tread spraying device 1 for tire production.

One end of the adjusting pump 72 is connected to the coating tank 71, and the other end of the adjusting pump 72 passes through the fourth supporting part 213 of the frame 21 and is connected to the spray pipe 73. The spray pipe 73 is connected to the spray head 74. The spray pipe 73 and the spray head 74 are arranged on the lower surface of the fourth supporting part 213 of the frame 21.

[0072] By adopting the above technical solution, the first driving member 31 can drive the first rotating shaft 4 to drive the tire to rotate 360°. The second part 82 and the third part 83 are respectively fixedly installed at both ends of the first part 81. Therefore, when the first driving member 31 drives the first rotating shaft 4 to drive the first part 81 to rotate, the second part 82 and the third part 83 will follow the first part 81 to rotate with the first rotating shaft 4 as the axis, and the rotatable angle is also 360°.

[0073] It should be noted that the embodiments of the present application do not impose any specific restrictions on the shapes of the first part 81, the second part 82 and the third part 83.
