Description

Technical Field

[0001] The present application relates to the technical field of tire production, and in particular to a tire blank conveying line blocker. Background Art

[0002] With the reform of industrial automation, many domestic tire companies have been vigorously optimizing the automatic logistics system of tire production in recent years. Placing semi-finished tire blanks on pallets and realizing automatic transportation, stopping, centering and operation on the logistics conveyor line are extremely important links, among which the stopping of the tire blank pallet is an indispensable process requirement for each of the above links. When the tire blank pallet and the tire blank run quickly on the tire blank conveyor line at the same time, a very large impulse is generated instantly when the blocker blocks it, which will cause a violent collision between the blocker and the tire blank pallet. Therefore, the tire blank conveyor line uses a blocker with a buffering function.

[0003] The utility model disclosed in the publication number CN 204642944 U is a pipeline blocker with a buffer structure, such as Figure 1 As shown, it includes a base 1, two guide sliders 4 and a blocker body 2 arranged in sequence from bottom to top, each guide slider 4 is connected to the base 1 through a guide mechanism 3, the blocker body 2 is installed on the guide slider 4, a hydraulic buffer 5 is installed on the front side of the base 1, the hydraulic buffer 5 is used to block the guide slider 4 from moving forward on the guide mechanism 3, a first pneumatic device 6 is installed on the base 1, the output end of the first pneumatic device 6 is connected to the guide slider 4 and is used to drive the guide slider 4 to move backward on the guide mechanism 3 to achieve reset, which can make the blocker as a whole slowly decelerate to stop. The guide mechanism 3 includes two guide rod supports 32 installed on the front and rear sides of the base 1 and guide rods 31 connected to the two guide rod supports 32 at both ends, the guide rod 31 passes through the guide through hole 41 on the guide slider 4, and a bushing 42 is installed in the guide hole 41 of the guide slider 4, and the bushing 42 is fitted on the guide rod 31. The blocker body 2 includes a support 24 and an L-shaped connecting plate 22 located above the support 24. The upper end of the L-shaped connecting plate 22 is hinged to the blocking wheel 21. The lower end of the rear side of the L-shaped connecting plate 22 is hinged to the upper end of the support 4. An intermediate support 23 is arranged below the curved portion of the L-shaped connecting plate 22. The upper end of the intermediate support 23 is hinged to the curved portion of the L-shaped connecting plate 22. A second pneumatic device 25 is arranged at the front side of the intermediate support 23. The output end of the second pneumatic device 25 is hinged to the lower end of the intermediate support 23. The lower end of the intermediate support 23 is pushed backward by the second pneumatic device 25, thereby driving the blocking wheel 21 to move downward. The two guide sliders 4 are symmetrically arranged. The second pneumatic device 25 is fixedly mounted on the two guide sliders 4 and located at the middle front side. The blocker body 2 is fixedly mounted on the two guide sliders 4 through the lower end of the support 24. The blocker has a buffering function, which can buffer the very large impulse generated instantly when the blocker blocks the embryo tray.

[0004] However, it was found during use that after long-term use, the hydraulic buffer 5 failed, resulting in a violent collision without buffering after the tire blank tray was blocked by the blocker. At this time, the blocker needs to be replaced. The replacement process is time-consuming and labor-intensive, and often occurs during production, affecting the normal production schedule of tires. Summary of the invention

[0005] The purpose of the utility model is to solve the deficiencies of the above-mentioned technology and provide a tire blank conveying line blocker which is installed on a tire blank tray and used in conjunction with an existing blocker to extend the service life of the existing blocker and ensure that the normal production arrangement of tires is not affected by it.

[0006] To this end, the utility model provides a tire blank conveying line blocker, which is provided with a mounting seat, on which a rubber pad is installed, and the rubber pad is provided with a blocking wheel collision surface and a blocking wheel withdrawal surface, and the blocking wheel withdrawal surface is arranged at the bottom of the blocking wheel collision surface; the blocking wheel withdrawal surface is an inclined surface, and the angle between the blocking wheel withdrawal surface and the vertical line is set to be an angle α; the higher side of the inclined surface is flush with the blocking wheel withdrawal surface, and the lower side of the inclined surface extends to the bottom of the rubber pad.

[0007] Preferably, the angle α is 4 to 7°.

[0008] Preferably, the collision surface of the blocking wheel is a planar structure.

[0009] Preferably, a blocking wheel locating groove is formed on the blocking wheel collision surface, and one side of the blocking wheel locating groove extends to the blocking wheel withdrawal surface.

[0010] Preferably, the bottom of the blocking wheel positioning groove is an inclined surface, and the lower side of the inclined surface is connected to the blocking wheel withdrawal surface.

[0011] Preferably, the angle β between the bottom of the blocking wheel positioning groove and the vertical line is smaller than the angle α.

[0012] Preferably, the angle β is 1 to 3°.

[0013] Preferably, an installation mark is provided in the middle of the mounting seat.

[0014] The beneficial effects of the utility model are as follows: the utility model provides a tire blank conveying line blocker which is installed on a tire blank tray and used in conjunction with an existing blocker; the rubber pad is provided with a blocking wheel collision surface and an inclined blocking wheel withdrawal surface.

[0015] On the one hand, when the green tire tray is blocked by the existing blocker, the collision surface of the blocking wheel collides with the blocking wheel of the existing blocker. Under the joint buffering effect of the utility model and the existing blocker, the green tire tray is smoothly blocked and stopped by the existing blocker; under the buffering effect of the collision surface of the blocking wheel, the frontal impact of the green tire tray on the existing blocker is greatly reduced, and the service life of the existing blocker is greatly extended.

[0016] On the other hand, when the embryo tray needs to be released, the blocking wheel of the existing blocker moves downward, and under the forward push of the embryo conveyor line, the blocking wheel passes through the blocking wheel withdrawal surface, and finally the two are separated, and the embryo tray is freed from the blocking restraint and continues to move forward with the embryo conveyor line. The inclined surface of the blocking wheel withdrawal surface of the utility model is set to be inclined backward relative to the forward direction of the embryo tray, so that the existing blocker and the utility model are easier to separate, reducing the lateral force on the existing blocker and extending the service life of the existing blocker.

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. The methods used in the present utility model are conventional methods unless otherwise specified; the raw materials and devices used are conventional commercial products unless otherwise specified.

[0030] Example 1

[0031] Depend on Figure 2 , Figure 3 As shown, the utility model provides a tire blank conveying line blocker, which is installed on a tire blank tray and used in conjunction with an existing blocker; the utility model is provided with a mounting seat 7, on which a rubber pad 8 is installed; the rubber pad 8 is provided with a blocking wheel collision surface 9 and a blocking wheel withdrawal surface 10, and the blocking wheel withdrawal surface 10 is connected and arranged at the bottom of the blocking wheel collision surface 9; the blocking wheel withdrawal surface 10 is an inclined surface, and the angle between the blocking wheel withdrawal surface 10 and the vertical line is set to angle α; the higher side of the inclined surface is flush with the blocking wheel withdrawal surface 10, and the lower side of the inclined surface extends to the bottom of the rubber pad 8.

[0032] The angle α is preferably 4-7°. When the embryo tray needs to be released, the blocking wheel 21 of the existing blocker moves downward, so that the existing blocker and the utility model can be separated smoothly.

[0033] The blocking wheel collision surface 9 is preferably a planar structure, so that the blocking wheel collision surface 9 collides and contacts with the blocking wheel 21 of the existing blocker as a whole.

[0034] The rubber pad 8 used in the present invention is a pad-shaped structure made of existing rubber. As is known to all, the most valuable property of rubber is high elasticity. Therefore, the rubber pad 8 has high elasticity.

[0035] The utility model is installed in the middle of the front part of the tire blank tray through the mounting seat 7, and the tire blank conveying line is installed with an existing blocker with a buffering function. During the production process, after the tire blank is produced, the operator places the tire blank on the tire blank tray, and then the tire blank and the tire blank tray run together and quickly on the tire blank conveying line.

[0036] Depend on Figure 4 As shown, when the front of the embryo tray is blocked by the existing blocker, the existing blocker collides with the embryo tray, that is, the blocking wheel collision surface 9 of the rubber pad 8 of the utility model collides with the blocking wheel 21 of the existing blocker. Under the joint buffering action of the utility model and the existing blocker, the embryo tray is smoothly blocked and stopped by the existing blocker; under the buffering action of the rubber pad 8 of the utility model, the frontal collision of the embryo tray on the existing blocker is greatly reduced, the service life of the existing blocker is greatly extended, the replacement times of the existing blocker are reduced, and it is ensured that the normal production arrangement of the tire is not affected.

[0037] In the actual conveying process, the embryo tray is stopped by the existing blocker and is in a stationary state, but the embryo conveying line is still in operation, and at this time, the bottom of the embryo tray rolls and rubs against the embryo conveying line. When the embryo tray needs to be released, the blocking wheel 21 of the existing blocker moves downward, and under the forward push of the embryo conveying line, the blocking wheel 21 passes through the blocking wheel withdrawal surface 10 of the rubber pad 8 of the utility model, and finally the two are separated, and the embryo tray is freed from the blocking restraint and continues to move forward with the embryo conveying line.

[0038] It should be noted that the inclined surface of the blocking wheel evacuation surface 10 of the utility model is set to be inclined backward relative to the forward direction of the tire blank tray. Compared with being set to a vertical surface (hypothesis), the existing blocker is easier to separate from the utility model, and the lateral force from the tire blank tray on the existing blocker is reduced, thereby extending the service life, thereby reducing the number of replacement times of the existing blocker and ensuring that the normal production arrangement of the tire is not affected.

[0039] Example 2

[0040] Depend on Figure 5-Figure 7 As shown, Example 2 provides a tire blank conveying line blocker, which is improved as follows on the basis of Example 1:

[0041] The blocking wheel collision surface 9 is provided with a blocking wheel positioning groove 11, and one side of the blocking wheel positioning groove 11 extends to the blocking wheel withdrawal surface 10. When the existing blocker collides with the tire blank tray, the blocking wheel 21 of the existing blocker enters the blocking wheel positioning groove 11 of the utility model, and due to the limiting effect of the blocking wheel positioning groove 11, the collision process between the two is smooth and reliable.

[0042] The bottom of the blocking wheel positioning groove 11 is preferably an inclined surface, and the lower side of the inclined surface is connected to the blocking wheel withdrawal surface 10. When the tire blank tray needs to be released, the blocking wheel 21 of the existing blocker moves downward and smoothly transitions from the bottom of the blocking wheel positioning groove 11 to the blocking wheel withdrawal surface 10.

[0043] The angle β between the bottom of the blocking wheel positioning groove 11 and the vertical line is preferably smaller than the angle α. The blocking wheel 21 of the existing blocker moves downward, and the transition from the bottom of the blocking wheel positioning groove 11 to the blocking wheel withdrawal surface 10 is further smooth. The angle β is preferably 1-3°.

[0044] The middle part of the mounting base 7 is preferably provided with an installation mark 12. When the utility model is installed in the front middle of the front part of the tire embryo tray through the mounting base 7, the two are convenient for centering, making the utility model simple and quick to install.
