Description

Technical Field

[0001] The invention relates to the technical field of tire belt layer preparation, and in particular to a method and equipment for preparing a tire ultra-small angle belt layer. Background Art

[0002] As the only part of a car that comes into contact with the ground, tires have an important impact on key vehicle performance such as rolling resistance, anti-skid performance, and vibration reduction performance. The belt layer is the core component of the radial tire structure, and its performance largely determines the overall quality and performance of the tire.

[0003] The existing tire belt preparation technology is to produce a large roll of steel cord fabric through a calendering line, and then pass it through a bias cutting line according to the following process steps: the large roll of steel cord fabric is unwound → cut into small pieces of steel cord fabric → the small pieces of steel cord fabric are sewn into a continuous steel belt layer → the steel belt layer is rolled up and collected.

[0004] Manufacturing tire belt layers through the bias cutting production line is a very mature preparation method in the industry. Steel wire and rubber are compositely wound on a calender to form a large steel cord roll, which is then transferred to a small-angle cutting machine (the conventional cutting angle is adjustable from 15° to 75°. Due to mechanical structure limitations, it is impossible to cut at a smaller angle) for cutting. When cutting, the large cord roll needs to be guided open, the corners cut off (the cut part is scrapped), and then the cutting operation can be carried out. The cutting angle error of the equipment can be controlled within ±0.5°. This production mode has high production efficiency and is suitable for large-scale production of belt layers at a single angle, but the material waste is also relatively large. The finished belt layer is rolled up onto a trolley or I-shaped wheel together with the pad cloth and transferred to the forming machine for use.

[0005] The cutting capacity of conventional bias cutting production lines can only meet the range of 15°~75°, and the maximum cutting width is 850mm. In recent years, breakthroughs have been made in the delivery stroke, cutting blade length and stitching stroke of bias cutting production lines, and online cutting and stitching of small angle belt layers in the range of 10°~15° can be achieved. However, in the tire design process, a belt layer design scheme with a smaller angle of 4°~10° and a width of 1000mm was proposed, which cannot be achieved by traditional belt layer production technology.

[0006] Under the same large roll steel cord width, the cutting angle of the tire belt layer is limited by the length of the cutter blade. At present, the domestic cutter production capacity has a maximum effective blade length of 4000mm. If you need to cut a belt layer in the range of 4°~10°, you need to press the calendered cord by 300mm. This will reduce the efficiency of the calendering production line. At the same time, due to the limitation of the delivery distance, the cutting width range is also limited. When cutting a 5° belt layer, the widest width can only be cut to 437.5mm. It cannot meet the design requirements of the width of the belt layer of medium and large engineering tires, and the steel wire structure of the large roll steel cord is different for different tire types. The diameter of the large roll steel cord ranges from 1mm to 5mm, and the steel wire structure is also different. According to the existing cutting method, the 4°~10° belt layer is cut, and the cutting angle of the cord steel cord is also 4°~10°. The cutting mouth is very long. For a 5mm diameter steel cord, the cutting surface reaches a cross-section of 57.15mm, which directly leads to the scattered wires of the steel cord cutting mouth, affecting the tire design performance. The steel cord with external winding is more serious. Summary of the invention

[0007] In order to solve the above technical problems, the present invention provides a method and equipment for preparing ultra-small angle belt layers of tires, which can realize the preparation of belt layers of any width with ultra-small angles of 4°~10°, meet the belt layer cutting capacity of any width, and achieve the belt bonding requirements of different widths and angles under different narrow cord strip widths.

[0008] A method for preparing an ultra-low angle belt layer of a tire according to the present invention comprises the following steps: S1. The preparation method of the wide and large roll steel cord fabric is adjusted to the preparation method of the narrow cord fabric strip, and the narrow cord fabric strip is directly extruded into shape by an extruder, and then collected by an I-shaped wheel and an isolation pad; S2, the narrow cord strips collected in S1 are processed by online unwinding, material storage, tension control, online length setting, and online cutting, and then enter the winding and laminating head device; the narrow cord strip rolls are unwinded by the unwinding device, the isolation pad is peeled off, and then the storage device and the tension control device are passed to the winding and laminating head device; S3. The winding and laminating head device interacts with the forming drum information. The winding and laminating head device actively conveys the narrow cord strips while the forming drum rotates. The forming drum rotates to cooperate with the winding and laminating head device to move from left to right or from right to left to achieve online lamination of the narrow cord strips. Finally, through the lamination of multiple narrow cord strips, the tire belt layer is completely pasted at ultra-small angles and any width. S4. Through the measurement of the bonding program, under different narrow cord strip widths, by controlling the winding and bonding head device to move in coordination with the forming drum, the belt bonding requirements of different widths and angles can be achieved; the tire belt layer is conventionally designed to be 3 to 6 layers, and the width design and angle design of each layer are different. In this case, multiple narrow cord strips are used to collage a complete belt layer. Compared with the existing technical solution that uses a small number of wide cord strips to collage a completed belt layer, it is impossible to prepare an ultra-small angle and arbitrary width belt layer.

And so on, combined with the bonding program measurement, the belt bonding requirements of different widths and angles can be achieved under different narrow cord strip widths.

Compared with the traditional method of equal laminating angle and cutting angle of the belt layer, the steel cord cutting small angle section is small, the problem of scattered lines is reduced, and the cutting capacity of the belt layer of any width is met.

[0010] Preferably, the winding and laminating head device has a rotation function, which can realize a rotation range of plus or minus 30°, and a fixed-length measuring device (not shown in the figure) is provided on the winding and laminating head device; the laminating requirements of belts of different widths and angles under different narrow cord strip widths are realized, thereby improving the processing accuracy and quality.

The strips are wound and collected, and then the first collecting device conveys the wound material roll to the first unwinding device, unwinds the material roll through the first unwinding device, and at the same time, the first unwinding device peels off the isolation pad cloth and the narrow cord strips, and then the first unwinding device conveys the narrow cord strips to the storage device, so that the storage device collects and stores the narrow cord strips, and then the narrow cord strips on the storage device are conveyed to the winding and bonding head device, and the narrow cord strips are pasted on the forming drum through the winding and bonding head device, and the narrow cord strips are conveyed by the winding and bonding head device in coordination with the rotation of the forming drum, so as to realize the online bonding of the narrow cord strips, and finally, through the bonding of multiple narrow cord strips, the complete collage of the tire belt layer with ultra-small angles and arbitrary widths is realized, the second collecting device has the same function as the first collecting device, and the second unwinding device has the same function as the first unwinding device, and the narrow cord strips are collected by the cooperation of the second collecting device and the second unwinding device, so as to improve the working efficiency of the equipment.

DETAILED DESCRIPTION

[0019] In order to facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive. Example

[0020] A method for preparing an ultra-low angle belt layer of a tire according to the present invention comprises the following steps: S1. The preparation method of the wide and large roll steel cord fabric is adjusted to the preparation method of the narrow cord fabric strip, and the narrow cord fabric strip is directly extruded into shape by an extruder, and then collected by an I-shaped wheel and an isolation pad; S2, the narrow cord strips collected in S1 are processed by online unwinding, material storage, tension control, online length setting, and online cutting, and then enter the winding and laminating head device; the narrow cord strip rolls are unwinded by the unwinding device, the isolation pad is peeled off, and then the storage device and the tension control device are passed to the winding and laminating head device; S3. The winding and laminating head device interacts with the forming drum information. The winding and laminating head device actively conveys the narrow cord strips while the forming drum rotates. The forming drum rotates to cooperate with the winding and laminating head device to move from left to right or from right to left to achieve online lamination of the narrow cord strips. Finally, through the lamination of multiple narrow cord strips, the tire belt layer is completely pasted at ultra-small angles and any width. S4. Through the laminating program, the laminating requirements of belts with different widths and angles can be achieved by controlling the movement of the winding laminating head device and the forming drum under different narrow cord strip widths; In this embodiment, the conventional design of the tire belt layer is 3 to 6 layers, and the width design and angle design of each layer are different. In this case, a plurality of narrow cord strips are used to collage a complete belt layer. Compared with the prior art solution that uses a small number of wide cord strips to collage a completed belt layer, it is impossible to prepare a belt layer with an ultra-small angle and any width. The preparation of a belt layer with an ultra-small angle of 4° to 10° and any width is achieved. When the first layer of the tire belt layer is bonded, the winding and bonding head device moves from left to right with the narrow cord strips, and the forming drum rotates clockwise at this time. When the second layer of the tire belt layer is bonded, the winding and bonding head device moves from left to right with the narrow cord strips, and the forming drum rotates clockwise. Move to the left, at this time the forming drum rotates counterclockwise, and so on, and combined with the bonding program measurement, so as to achieve different widths and angles of belt bonding under different narrow cord strip widths. In order to solve the problem of long scattered lines in small-angle cross-section when cutting steel cord, the cutting position of the winding bonding head is designed to be angle-adjustable. By designing the actual cutting angle capacity of 30°~60°, there is a difference in the design of the bonding angle and cutting angle of the narrow cord strip. Compared with the traditional method of equalizing the bonding angle and cutting angle of the belt layer, the steel cord can be cut at a small angle with a small cross-section, reducing the problem of scattered lines, and at the same time meeting the cutting capacity of the belt layer of any width.
