Description

Technical Field

[0001] The present invention relates to the technical field of tire glue spraying, in particular to a batch type tire glue spraying device. Background Art

[0002] A tire glue sprayer is an automated device specifically designed for spraying glue during tire manufacturing or retreading. Its primary function is to precisely and evenly apply adhesive. By spraying glue on new tires, it not only prevents air infiltration, maintains stable tire pressure, reduces fuel consumption, and extends tire life, but also automatically fills holes in the event of a nail puncture, delaying air leaks and improving driving safety. Currently, glue sprayers require specialized fixtures to effectively secure the tire and rotate it at a constant speed, allowing for even application of glue to the tire's interior. This is exemplified by the glue sprayer disclosed in Patent Publication No. CN114618730A. However, this glue spraying machine still has some shortcomings in actual use: first, the working efficiency is low, and it can only spray glue on tires one by one, which requires frequent loading and unloading of tires, which is time-consuming and labor-intensive, and is especially not suitable for batch glue spraying operations; second, the cooling effect of the cooling process after glue spraying is not obvious on the tire. Since the fan blades are set on the outside of the tire, the wind generated cannot blow directly into the tire. Often after the spraying is completed, the glue cannot dry thoroughly and is easily touched when loading and unloading the tire, thereby affecting the overall glue spraying effect of the tire. Summary of the Invention

[0003] In order to make up for the deficiencies of the prior art, the present invention provides a batch tire glue spraying device, which has a reasonable structural design, is easy to operate, and can load and unload tires in batches. A single glue spraying can not only perform a uniform glue spraying process on multiple tires, but also greatly improve the glue spraying efficiency. There is no need for frequent manual participation and coordination with equipment, which saves time and effort. In addition, the tire can be effectively cooled from the inside, the cooling speed can be increased, and the glue can be dried quickly, which is convenient for subsequent loading and unloading of tires. Even touching the inside of the tire will not affect the glue spraying effect on the entire tire, thus solving the problems existing in the prior art.

The cylinder 30 is provided with a plurality of expansion rollers 32 arranged in a uniform interval along its circumferential direction through the cams 31 provided at its left and right ends, which are movably engaged with the circular grooves 29 of the clamping plate 26 on the corresponding side.

[0035] Optionally, the transmission mechanism includes a driven gear 33 sleeved on the outer wall of the drum 30, a transmission motor 34 is provided on the sliding base 25 outside the drum 30, and a driving gear 35 meshing with the driven gear 33 is sleeved on the output shaft of the transmission motor 34.

[0036] Optionally, the transverse movement mechanism includes a transverse movement groove 36 opened on the surface of the base plate 1 along the length direction of the base plate 1, and the sliding base plate 25 is movably clamped in the transverse movement groove 36 of the base plate 1, and transverse movement blocks 37 are symmetrically provided on the front and rear sides of the sliding base plate 25 along its length direction, and transverse movement grooves 38 corresponding to the position of the transverse movement block 37 are provided on the front and rear sides of the inner wall of the transverse movement groove 36 respectively. A transverse movement motor 39 is provided on the base plate 1 on the left side of the transverse movement groove 36, and the output shaft of the transverse movement motor 39 is connected to the horizontally arranged screw 40. The right end of the screw 40 is threaded through the two clamping plates 26 in sequence and clamped on the side wall of the support plate 26 on the right.

[0037] The operation of this device is divided into the following five steps:

[0038] S1. Tire placement:

[0039] Move the tire to the space on the right side of the fixing plate 6, so that the inner ring of the tire is clamped into the fixing plate 6 and moved to the side of the extrusion plate 10. At this time, the tire is clamped on each support rod 9. In this way, other tires are placed one by one on the outside of the support sleeve 7.

[0040] S2. Squeezing of the gap between tires:

[0041] First, the support cylinder 8 is activated. Its piston rod extends outward, pushing the support sleeve 7 to the right along the stop sleeve 5 until the support cylinder 8 is fully extended. Then, the traverse motor 39 is activated. Its output shaft rotates the lead screw 40, thereby moving the clamping plate 26, which is threadedly connected to it, to the left. The sliding base plate 25 then moves smoothly within the traverse slot 36. The front and rear traverse blocks 37 move within the traverse slots 38, guiding the movement of the sliding base plate 25. This continues until the clamping plate outside the second channel 28 abuts the outermost tire of the support sleeve 7. The traverse motor 39 is then deactivated. Finally, the extrusion cylinders 11 are activated. Their piston rods push the extrusion plate 10 to the right, pushing the tires to the right of the extrusion plate 10, gradually bringing them into close contact and effectively eliminating any gaps between them.

[0042] S3. Tire clamping:

[0043] Each expansion roller 32 is activated, causing its expansion block to move outward, thereby pushing the corresponding clamping plate 41 inward toward the drum 30 until it contacts the tire's tread. Because the fixed plate 6 and the drum 30 are coaxially arranged, the clamping process separates the tire, which was previously dangling from the support rod 9. The traverse motor 39 and support cylinder 8 are then activated, returning the drum 30 and traverse drum 4 to their initial positions.

[0044] S4. Tire glue spraying:

[0045] First, the transmission motor 34 is activated. This drives the driven gear 33 via the drive gear 35, thereby rotating the roller 30 radially. The roller 30, in turn, rotates within the circular slots 29 of the two clamping plates 26 via the left and right latches 31. The rodless cylinder 19 is then activated, moving leftward on the transverse rod. During this movement, the nozzles of the glue sprayer 20 gradually complete the glue spraying process inside each tire. The fan's outlet duct is connected to the inlet duct 23. The air generated by the fan enters the cavity 22 through the inlet duct 23 and is ejected outward through the various spray nozzles 24, directly blowing into the interior of each tire, cooling the tire while simultaneously spraying glue. Tires can be loaded and unloaded in batches, and a single glue spraying process can be performed on multiple tires evenly, which greatly improves the glue spraying efficiency. There is no need for frequent manual participation and coordination with equipment, saving time and effort. In addition, the tire can be effectively cooled from the inside, increasing the cooling speed and allowing the glue to dry quickly, making it convenient for subsequent tire loading and unloading. Even touching the inside of the tire will not affect the overall glue spraying effect of the tire.

[0046] S5. Tire removal:

[0047] Following the above method, the fixing plate 6 is re-inserted into the tire and the inflatable rollers 32 are reset, thereby re-engaging the tire on the support rods 9. Finally, after the fixing plate 6 and the rollers 30 are restored to their initial positions, the tires can be manually disassembled and removed one by one from the support rods. During this process, the squeezing cylinder 11 can also be used to push the squeezing plate 10 to push the tire to the right end of the support rod 9, making it easier for workers to remove the tires.
