Description

Technical Field

[0001] This utility model relates to the technical field of rubber strip blowing, specifically to a rubber strip blowing device for aircraft tire sidewalls. Background Technology

[0002] In the production of aircraft tires, there is a rubber strip lamination process. The rubber strips used are unvulcanized rubber strips produced by rubber refining and extrusion calendering. The rubber strips are processed at high temperatures and are cooled after output to ensure good processability. Generally, this is done by direct water spraying or cooling in a water tank. After cooling, the surface of the rubber strips has water droplets. Before conveying them to the next process or storing them, the moisture on the surface of the rubber strips needs to be removed.

[0003] For example, Chinese utility model patent CN209718399U discloses a rubber strip blowing device, belonging to the field of rubber strip processing technology. The device includes an air outlet box above the conveyor table and an adjusting component that controls its movement. The air inlet, connected to the high-pressure gas pipeline, is located on a hollow, inverted trapezoidal box. The lower end of the box is open, forming an air outlet. A telescopic rod on a cylinder connected to a lower fixing component is connected to a connector, which is then connected to a support rod on the box via a connecting rod. Beneficial technical effects: The inverted trapezoidal structure of the air outlet box provides a buffer against the high-pressure gas, making it suitable for drying rubber strips using high-pressure gas. The adjusting component allows the air outlet box to swing back and forth, changing the direction of the high-pressure gas flow, extending the contact time between the rubber strip and the gas, improving drying efficiency, and shortening drying time.

[0004] However, since both sides of the rubber strip need to be purged, after purging the surface of the rubber, the rubber strip needs to be reversed before it can be purged again after purging the moisture on the lower surface, which results in low purging efficiency of the device for the rubber strip. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an aviation tire sidewall rubber strip blowing device that facilitates simultaneous blowing of both sides of the colloid, improves the blowing efficiency of the device for the rubber strip, and enhances its practicality.

[0006] This utility model discloses an aviation tire sidewall rubber strip blowing device, including a workbench, two upright plates symmetrically fixedly installed on the top of the workbench, multiple support mechanisms arranged between the two upright plates, and a blowing mechanism arranged between the two upright plates; the support mechanism includes a rotating shaft, which is horizontally rotatably installed between the two upright plates, and a rotating roller is fixedly installed on the outer wall of the rotating shaft. The purging mechanism includes two drain pipes, which are symmetrically and obliquely fixed on the outer wall of one of the vertical plates. The output end of each drain pipe is connected to multiple nozzles, and a blower mechanism is set between the two drain pipes. Two guide tubes are symmetrically and obliquely fixedly installed on the top of the workbench via multiple support columns. The input end of each guide tube is located outside the output end of each nozzle. A protective plate is fixedly installed on the top of the workbench, and multiple guide mechanisms are provided on the protective plate. The guiding mechanism includes a cone block, and a connecting hole is provided on the guard plate. One end of the cone block is fixedly mounted on the inner wall of the connecting hole by multiple brackets. Multiple drainage holes are transversely provided on the cone block. This aircraft tire sidewall rubber strip blowing device moves the rubber strip to the outer wall of the upper rotating roller, then winds the rubber strip around the outer wall of the rotating roller at the end away from the upper rotating roller, and then winds the rubber strip around the rubber strip at the lower side. Compressed air is discharged through the drain pipe and nozzle. The air discharged through the nozzle is guided by the guide pipe. The end of the guide pipe away from the nozzle blows air through the two ends of the rubber strip between the two adjacent rotating rollers. The water being blown is diverted by one end of the cone block and then discharged through the drain hole and connecting hole into the space between the upright plate and the guard plate. This facilitates simultaneous blowing of both sides of the rubber strip, improves the blowing efficiency of the device, and enhances its practicality.

[0007] Preferably, the blower mechanism includes an air pump, which is fixedly installed on the outer wall of one of the upright plates. The output end of the air pump is connected to a second connecting pipe through a first connecting pipe. The top and bottom ends of the second connecting pipe are respectively connected to the input ends of two drain pipes. When the air pump is started, the compressed air is passed through the first and second connecting pipes, and then through the drain pipes and sprayed out through the nozzle.

[0008] Preferably, a collection trough is fixedly installed at the top of the workbench. The collection trough is located between one of the upright plates and the guard plate. An inclined plate is fixedly installed at the top of the collection trough at an angle. Two sealing plates are symmetrically fixedly installed on the outer side wall of the inclined plate. A drain valve is connected to one end of the collection trough. Water discharged through the connection hole is guided by the inclined plate and then collected through the collection trough.

[0009] Preferably, two guide plates are symmetrically fixedly installed on the outer side wall of each guide tube near the nozzle end. By installing the guide plates, it is convenient to guide the air discharged through the nozzle.

[0010] Preferably, two support plates are symmetrically fixedly installed on the top of the workbench, and multiple conveying rollers are rotatably installed on the top of the two support plates to support and convey the rubber strips to be blown through the conveying rollers.

[0011] Preferably, multiple limiting shafts are rotatably installed in the bottom area of ​​the two upright plates, and a limiting roller is rotatably installed on the outer side wall of each limiting shaft. The limiting shafts and limiting rollers facilitate the support and conveying of the blown rubber strip.

[0012] Preferably, a motor is fixedly installed at one end of one of the rotating shafts. The motor is fixedly installed on the outer wall of one of the vertical plates. When the motor is started, it outputs power to synchronously drive the rotating shaft and the rotating roller to rotate, thereby conveying the rubber strip.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This aviation tire sidewall rubber strip blowing device moves the rubber strip to the outer wall of the upper rotating roller, then wraps the rubber strip around the outer wall of the rotating roller at the end away from the upper rotating roller, and then wraps the rubber strip around the rubber strip at the lower side. Compressed air is discharged through the nozzle through the drain pipe, and the air discharged through the nozzle is guided through the guide pipe. The end of the guide pipe away from the nozzle and the two ends of the rubber strip between the two adjacent rotating rollers are blown by air. The water being blown is diverted by one end of the cone and discharged through the drain hole and the connecting hole into the space between the upright plate and the guard plate. This facilitates simultaneous blowing of both sides of the rubber strip, improves the blowing efficiency of the device, and enhances its practicality. Attached Figure Description
