Description

Technical Field

[0001] The utility model relates to the technical field of processing equipment, in particular to a processing equipment for a puncture-proof sheet of a tire. Background Art

[0002] At present, there are two types of vehicle wheels used in vehicles. One is a vehicle wheel with an inner tube, and the other is a tubeless vehicle wheel. Currently, almost all passenger vehicles use tubeless vehicle wheels, and heavy-duty vehicles are required by the state to gradually promote the use of tubeless vehicle wheels. Tubeless vehicle wheels have the advantages of good heat dissipation, softness, sealing performance, good riding comfort, and long inflation interval. However, when the tire of a tubeless vehicle wheel is punctured by a sharp object, since the sharp object remains in the vehicle tire body, the high-pressure gas in the vehicle wheel tire will leak out or cause a tire explosion at the puncture site; when the sharp object pierces through the vehicle tire and detaches from the vehicle tire, the high-pressure gas in the tubeless vehicle wheel leaks rapidly. If a tire explosion or rapid leakage occurs during the high-speed driving of the vehicle, the risk of vehicle accidents is high, and the probability of vehicle destruction and human death is high.

[0003] In order to change this situation, people use a spray gun to spray a layer of hot melt adhesive with a memory function inside the tire. When the vehicle tire presses over an object with a relatively sharp external shape, the tire is punctured, but the hot melt adhesive layer can close the punctured hole on the tire, making the tire airtight and avoiding accidents. Then, using a spray gun to spray hot melt adhesive inside the tire easily leads to uneven spraying, affecting the dynamic balance of the tire, resulting in jitter and instability during vehicle operation. Summary of the Invention

[0004] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a processing equipment for a puncture-proof sheet of a tire. The hot melt adhesive is pressed and covered on the sheet body through the processing equipment, so that the hot melt adhesive is uniform and flat without affecting the use.

[0005] The technical solution of the utility model: A processing equipment for a puncture-proof sheet of a tire includes a frame. A first unwinding cylinder for winding and shaping paper, a second unwinding cylinder for winding release paper, a glue bucket for containing hot melt adhesive, a first roller and a second roller are arranged on the frame. The two rollers are spaced apart to form a material passing channel, and the glue outlet of the glue bucket is arranged corresponding to the material passing channel. A first pressure roller and a second pressure roller are oppositely arranged on the frame. The two pressure rollers are spaced apart to form a material pressing channel for the sheet to pass through, and the material pressing channel is communicated with the material passing channel.

[0006] With the above technical solution, the sizing paper and the release paper enter the material passing channel from the corresponding feeding cylinders. The hot melt adhesive in the glue bucket flows out from the glue outlet, flows into the material passing channel, and is located between the sizing paper and the release paper. Through the pressing of the two rollers, the hot melt adhesive adheres to the sizing sheet, and the release paper covers the outside of the hot melt adhesive to form a sheet material, which is conveyed towards the material pressing channel. The sheet material is compacted through the material pressing channel, so that the hot melt adhesive adheres better to the sizing paper. When the sheet material needs to be installed on the inner side of the tire, the release paper is torn off, so that the hot melt adhesive contacts the inner side wall of the tire and adheres to the inner side wall of the tire. The sheet material processed by the processing equipment is more uniform and will not affect the dynamic balance of the tire. The length of the sheet material is cut according to the tire size.

[0007] A further setting of the present utility model: A detachable positioning plate is provided on the frame. The positioning plate is partially located between the two rollers. The second roller can slide along the transverse direction of the frame to adjust the distance between the second roller and the first roller.

[0008] With the above further setting, the distance between the two rollers is the thickness of the sheet material. By replacing the positioning plate, the distance between the rollers is adjusted to process sheet materials of different thicknesses.

[0009] A still further setting of the present utility model: A connecting rod is provided above the two rollers on the frame. There are two positioning plates. The two positioning plates are installed on the connecting rod and can slide on the connecting rod to adjust the distance between the two positioning plates.

[0010] With the above still further setting, by adjusting the positions of the two positioning plates on the connecting rod, the width of the sheet material is determined. The distance between the two positioning plates is the width of the sheet material, and sheet materials of different widths can be processed according to needs.

[0011] A yet further setting of the present utility model: A guiding plate is also provided on the frame. The guiding plate is located between the material passing channel and the material pressing channel. One end of the guiding plate facing the material passing channel is inclined.

[0012] With the above yet further setting, it plays a guiding role, facilitating the sheet material to slide from the material passing channel into the material pressing channel, making the movement of the sheet material smoother.

[0013] A yet further setting of the present utility model: A first water tank is provided below the first roller on the frame and a second water tank is provided below the second roller. The lower end of the first roller is located in the first water tank, and the lower end of the second roller is located in the second water tank.

[0014] With the above yet further setting, it avoids the temperature of the rollers being too high and affecting the sheet material.

[0015] A further improvement of the present utility model: A third pressure roller and a fourth pressure roller are further provided on the frame. The third pressure roller and the fourth pressure roller are arranged separately, and the third pressure roller and the fourth pressure roller are located at the rear side of the first pressure roller and the second pressure roller. The second pressure roller and the fourth pressure roller can slide on the frame to adjust the distance between them and the first pressure roller and the third pressure roller.

[0016] With the above further improvement, the sheet passes between the third pressure roller and the fourth pressure roller, further flattening the sheet, making the hot melt adhesive on the sizing paper more uniform and firm. The second pressure roller and the fourth pressure roller can slide, so that the distance can be adjusted to process different sheets, with high practicability. A receiving cylinder is provided at the rear end of the third pressure roller and the fourth pressure roller on the frame to wind up the sheet. Description of the Drawings

The rollers can be driven to rotate by driving parts such as motors and rotary cylinders. The shaping paper can be made of foam material. The shaping paper and the release paper enter the material passing channel 7 from the corresponding unwinding cylinders. The hot melt adhesive in the glue bucket 4 flows out from the glue outlet, flows into the material passing channel 7, and is located between the shaping paper and the release paper. Through the pressing of the two rollers, the hot melt adhesive adheres to the shaping sheet, and the release paper covers the outside of the hot melt adhesive to form a sheet, which is conveyed towards the material pressing channel 10. The sheet is compacted through the material pressing channel 10 to make the hot melt adhesive better adhere to the shaping paper. When the sheet needs to be installed on the inner side of the tire, the release paper is torn off, so that the hot melt adhesive contacts the inner side wall of the tire and adheres to the inner side wall of the tire. The sheet processed by the processing device is more uniform and will not affect the dynamic balance of the tire. The length of the sheet is cut according to the tire size. A tensioning wheel 19 is also provided on the frame 1 to prevent the shaping paper and the release paper from piling up during the transmission process.
