Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of nylon cord cutting, in particular to a nylon cord ultrasonic cutting device of a tire building machine and a process thereof. BACKGROUND

[0002] The nylon cord on the tire building machine is mainly cut by electrically heated broach, and the surface of the broach is adhered with rubber. Since the broach is always in a high-temperature heating state, the adhered rubber will be carbonized and deteriorated to form impurities. When cutting next time, the cutter will bring the impurities to the cord cutting surface to contaminate the cord, thereby affecting the quality. In addition, after cutting by the hot cutter, the cord originally adhered with rubber will occasionally have a head lifting situation after breaking away from the rubber layer, which has a greater impact on the tire quality.

[0003] Because different types of tires need different sizes of nylon cords for production, it is necessary to accurately cut the required nylon cord in a fixed length. The existing cutting method has poor adaptability, and the accurate positioning of the nylon cord and the angle adjustment of the cutter are difficult to cooperate. If the pressing position is too far, it is easy to cause the nylon cord to wrinkle during cutting. If it is too close, it is easy to interfere with each other, making it difficult to cut quickly. In addition, cutting the nylon cord is easy to produce a small amount of fine particles and dust, which splashes or drifts to other positions of the nylon cord, not only affecting the subsequent cutting of the nylon cord, but also affecting the stability of the positioning of the nylon cord.

[0004] In view of the above technical problems, Chinese patent application No. CN202222926771.6, a large-angle cord cutting device for air spring forming, is provided. The device includes a pressure holding mechanism arranged at the end of the linear module and adjustable in position along the axial direction of the linear module, and a cutter assembly fixed on the top surface of the linear module slider. An angle adjusting mechanism is arranged between the cutting support beam and the linear module. The pressure holding mechanism includes an inclined bottom plate fixed to the bottom end of the frame and abutting the surface of the conveyor belt, a pressure plate slidingly connected to the frame in the vertical direction, and a pressure holding cylinder connected to the pressure plate through a piston rod. A strip-shaped groove is arranged on the top surface of the inclined bottom plate, and a cutter groove is arranged on the pressure plate corresponding to the strip-shaped groove. A pressure roller assembly is arranged at the front of the belt conveyor. The device solves the problems of difficult and inefficient cutting of the cord, and accumulation and cutting of the nylon line.

[0005] Although the large-angle cord cutting device for air spring forming can cut, it cannot cut at multiple angles as needed, has poor adaptability, and is difficult to meet the needs of various tires. In addition, the cutting efficiency is poor, and the head lifting situation is easy to occur.

[0006] Therefore, a nylon cord ultrasonic cutting device of a tire building machine and a process thereof are proposed. SUMMARY

8. The process applicable to the ultrasonic cutting device for nylon cord fabric of a tire forming machine according to any one of claims 1-7, characterized in that: Includes the following steps; S1. The first servo motor (5) drives the second slide rail (9) and ultrasonic cutter (19) at the upper end of the first slider (8) to move back and forth to a suitable position, so as to make a rough selection of the cutting position. The second servo motor (10) drives the third slide rail (14) at the front end of the second movable block (12) and ultrasonic cutter (19) to move left and right, so as to make a precise cutting position. At the same time, the power of the left and right movement of the second movable block (12) drives the two sets of telescopic airbags (20) to extend and retract, continuously supplying air to the air duct (24), so that the first nozzle (25) cleans the nylon curtain (3), making it easier to clean the cutting position. S2, the fourth servo motor (28) and the fifth servo motor (30) drive the pressure block (35) at the bottom of the cylinder (32) to move to a suitable position, so as to select different pressing positions. Then the air pump (37) sends the outside gas into the upper space of the piston (33) inside the cylinder (32) through the second conveying pipe (38). The gas inside the cylinder (32) drives the pressure block (35) to press the nylon curtain (3) through the piston (33) and the connecting rod (34). While the upper space of the piston (33) inside the cylinder (32) is filled with air, the gas in the lower space of the piston (33) inside the cylinder (32) is sent to the second nozzle (43) through the third conveying pipe (41) for spraying. Thus, the second nozzle (43) cleans the dust and debris at the bottom of the pressure block (35), which helps to improve the stability of the pressure block (35) pressing the nylon curtain (3). S3. The third servo motor (15) drives the third lead screw (16) to rotate. The third lead screw (16) drives the third slide rail (14) at the front end of the third slider (18) to move up and down through the third movable block (17), so that the ultrasonic cutter (19) at the front end of the third slide rail (14) approaches the nylon curtain (3) for cutting. Then, through the cooperation of the first servo motor (5), the second servo motor (10) and the third servo motor (15), the nylon curtain (3) is driven to cut at various angles, which facilitates fast fixed-length cutting. S4. Finally, open the pressure relief valve (39). The restoring force of the return spring (36) will discharge the gas in the cylinder (32) through the piston (33) again from the second delivery pipe (38), thereby causing the pressure block (35) to rise and loosen the nylon curtain (3). Gas will be supplied to the lower space of the piston (33) inside the cylinder (32) through the second air inlet valve (40) for reuse.
