Description

Technical Field

[0001] The invention relates to the technical field of tire production, in particular to a steel wire winding device and a winding method for a radial tire. Background Art

[0002] A radial tire includes a tread, a cap layer, a sidewall, a belt layer, a wire ring, a carcass and an inner liner, etc. In the process of producing the wire ring, it is necessary to first use rubber to cover the steel wire to form a wire ring with multiple rows of steel wires inside, and then the wire ring is wound and shaped to obtain the wire ring. The core of the existing wire ring winding device is a continuously rotating hoop. In the production process, the wire ring conveying device conveys one end of the wire ring to the clamping port of the hoop, and then the hoop clamps and fixes one end of the wire ring and involves the wire ring to rotate and wind, so that the wire ring can be wound into a circle and shaped.

[0003] According to the Chinese patent application number 202311337551.2, a wire winding device and winding method for a radial tire reduce the problems of loosening, offset and uneven support force of the wire ring during the layered winding process, improve the winding production of the wire ring, and enhance the strength of the wire ring by one-time forming of a single-turn winding, so as to ensure uniform force on the tire. A wire winding device and winding method for a radial tire include a base, a hoop, a mounting mechanism, a pressurizing mechanism, a translation mechanism, a squeezing mechanism, and a clamping mechanism.

[0004] According to the above-cited application document, the free end of the steel wire is fixed by a mounting mechanism outside the hoop, and then the drive motor is started to rotate the hoop. At the same time, the extrusion roller presses the outer wall of the steel wire to make the steel wire close to the outer wall of the hoop, so that the steel wire is neatly wound and shaped according to the outer wall of the hoop. Since the tire needs to be changed according to the size of the wheel hub during the actual production process, it is necessary to replace hoops of different sizes to produce steel wire rings of different diameters. However, the application document requires replacing hoops to make steel wire rings of different sizes, which results in a lot of time and effort in the production of the steel wire rings, as well as the cumbersomeness of the production of the steel wire rings.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1

[0031] See also Figure 1-7 The present embodiment provides a wire winding device and a winding method for a radial tire, comprising a vertical plate 1, a mounting ring 12 and a winding plate 5, wherein the mounting ring 12 is detachably connected to one side of the vertical plate 1, the vertical plate 1 is set to a T-shaped structure, and a positioning ring adapted to the mounting ring 12 is rotatably installed on one side of the vertical plate 1 perpendicular to the ground, and a driving motor for rotating the positioning ring is fixedly installed on the other end of the vertical plate 1, wherein a transmission shaft is fixedly installed on one end of the positioning ring close to one side of the vertical plate 1, and the transmission shaft extends to the other side of the vertical plate 1 and is fixedly connected to the power output end of the driving motor. When the driving motor is started, the transmission shaft rotates together with the power output end of the driving motor, thereby realizing the rotation of the positioning ring.

[0032] A threaded cap 4 for positioning the mounting ring 12 is installed in the inner cavity of the positioning ring, and a spiral groove matched with the threaded cap 4 is opened on the inner wall of the positioning ring. The mounting ring 12 is sleeved on the outer wall of the positioning ring, and then the threaded cap 4 is installed inside the positioning ring. The threaded cap 4 is fixed with the cooperation of the spiral groove, and at the same time, one end of the threaded cap 4 is fitted with the end of the mounting ring 12 away from the vertical plate 1, thereby fixing the mounting ring 12, which is conducive to the synchronous rotation of the mounting ring 12 with the positioning ring.

[0033] There are multiple winding plates 5 movably installed in a ring-shaped distribution on the outer wall of the mounting ring 12. The outer wall of the winding plates 5 is bent, and four winding plates 5 are distributed in a ring-shaped distribution outside the mounting ring 12. The outer wall of one of the winding plates 5 is installed with a clamp for clamping the free end of the steel wire, and the outer wall of the mounting ring 12 is provided with a control component for controlling the distance of the multiple winding plates 5. After two adjacent winding plates 5 are in contact, the four winding plates 5 can form a complete circular ring structure, one end of the steel wire is fixed with a clamp, and then the driving motor is started. One end of the steel wire rotates with the clamp and is neatly wound around the outer walls of the four winding plates 5, which is conducive to the production and shaping of the steel wire ring.

[0034] The control component includes a sealing cylinder 10 and a push rod 9. The outer wall of the mounting ring 12 is fixedly installed with multiple sealing cylinders 10 in a circular distribution along a direction perpendicular to the outer wall of the mounting ring 12. Among them, the outer wall of the mounting ring 12 is fixedly installed with four sealing cylinders 10 in a circular distribution. The four sealing cylinders 10 correspond to the four winding plates 5.

[0035] A push rod 9 is elastically installed in the inner cavity of multiple sealing cylinders 10, and a push spring 18 is fixedly sleeved on the outer wall of the push rod 9. One end of the push spring 18 is fixedly connected to the inner wall of the sealing cylinder 10. The push spring 18 can apply a thrust to the push rod 9 to slide toward the mounting ring 12, which is beneficial to the rapid resetting of the push rod 9 after sliding.

[0036] One end of the push rod 9 away from the mounting ring 12 extends to the outside of the sealing cylinder 10 and is fixedly connected to one side of the winding plate 5. The outer wall of the mounting ring 12 is provided with conduits 11 in a ring-shaped distribution. The multiple conduits 11 and the multiple sealing cylinders 10 are staggered. The two ends of the multiple conduits 11 are respectively fixedly connected to the outer walls of two adjacent sealing cylinders 10. Four conduits 11 are installed in a ring-shaped distribution on the outer wall of the mounting ring 12. The two ends of each conduit 11 are respectively fixedly connected to the outer walls of two adjacent sealing cylinders 10. The inner cavities of the four sealing cylinders 10 are interconnected under the action of the four conduits 11.

[0037] An air pipe 13 connected to the inner cavity of one of the conduits 11 is fixedly installed on the outer wall of the conduits 11, and a sealing plug 19 that fits the inner wall of the sealing tube 10 is fixedly installed on the end of the push rod 9 away from the winding plate 5, wherein high-pressure air is injected into the interior through the air inlet end of the air pipe 13, and the high-pressure air flows through the four conduits 11 to enter the interior of the four sealing tubes 10. At this time, the air pressure between the bottom of the sealing tube 10 and the sealing plug 19 increases rapidly, thereby applying a thrust to the sealing plug 19 to move away from the mounting ring 12. When the air pressure is greater than the elastic force of the top pressure spring 18, the top pressure spring 18 is compressed and causes the push rod 9 to move away from the mounting ring 12. At this time, the four push rods 9 move simultaneously and move synchronously with the four winding plates 5.

[0038] Furthermore, after the four wrapping plates 5 move a certain distance, the injection of high-pressure gas into the air pipe 13 is stopped, and the air inlet end of the air pipe 13 is sealed to ensure that the air pressure inside the sealing tube 10 remains relatively stable. After the injection of high-pressure air is stopped, the push rod 9 stops sliding and remains stationary, thereby increasing the distance between the wrapping plates 5 and the mounting ring 12, and ensuring that the four wrapping plates 5 are at the same straight-line distance from the outer wall of the mounting ring 12, which is beneficial to changing the diameter of the wire ring and the production of wire rings of different sizes, while preventing the wire ring from being deformed, reducing the time and effort required for the production of wire rings of different sizes, as well as the complexity of the production of wire rings of different sizes.

[0039] The control component also includes an air pump 2, which is fixedly connected to the outer wall of the vertical plate 1, and a connecting hose is fixedly installed on the air outlet end of the air pump 2, and a connecting cap 3 is fixedly installed on the other end of the connecting hose. The inner wall of the connecting cap 3 and the outer wall of the air inlet end of the air supply pipe 13 are provided with corresponding threaded grooves. When the mounting ring 12 is in a stationary state, the connecting cap 3 and the air inlet end of the air supply pipe 13 are connected, and then the connecting cap 3 is rotated. With the cooperation of the threaded groove, the connection and fixation between the connecting cap 3 and the air supply pipe 13 are achieved, and then the air pump 2 is started. The air pump 2 absorbs external air and pressurizes the air, and then the pressurized air is transmitted to the inside of the air supply pipe 13 through the high-pressure air of the connecting hose, which is beneficial to pressurize the inside of the sealing tube 10 and allow the push rod 9 to slide. At the same time, the internal air pressure of the sealing tube 10 is controlled by controlling the working time of the air pump 2, thereby accurately controlling the moving distance of the push rod 9.

[0040] Furthermore, the connecting cap 3 and the air inlet end of the air pipe 13 are separated. At this time, the high-pressure air inside the sealing tube 10 is quickly depressurized through the air pipe 13. At the same time, the top pressure spring 18 is reset, which is conducive to improving the convenience of resetting the push rod 9.

[0041] A sealing ring 15 is fixedly installed on the inner wall of the air pipe 13, and a sealing plate 14 compatible with the sealing ring 15 is slidably installed in the inner cavity of the air pipe 13. The sealing ring 15 is located between the air inlet end of the air pipe 13 and the sealing plate 14, wherein the diameter of the sealing plate 14 is larger than the inner diameter of the sealing ring 15 and smaller than the inner diameter of the air pipe 13. When the sealing plate 14 and one end of the sealing ring 15 are in contact, they serve to separate the two ends of the air pipe 13, preventing the high-pressure air inside the sealing tube 10 from exchanging with the outside air through the air pipe 13, which is beneficial to sealing the sealing tube 10 and the inner cavity of the conduit 11.

[0042] A guide rod 16 is fixedly installed at one end of the sealing plate 14 away from the sealing ring 15, and a return spring 20 connected to the inner wall of the air pipe 13 is fixedly sleeved on the outer wall of the guide rod 16, wherein the return spring 20 applies a thrust to the guide rod 16 to continuously slide toward the sealing ring 15, which is beneficial to improve the tightness of the fit between the sealing plate 14 and the sealing ring 15.

[0043] Furthermore, when high-pressure air is provided to the inside of the connecting cap 3 through the connecting hose, the air pressure in the chamber between the connecting cap 3 and the sealing plate 14 increases. When the air pressure increase is greater than the elastic force of the return spring 20, the return spring 20 is compressed and causes the sealing plate 14 and the sealing ring 15 to separate, which is conducive to allowing high-pressure air to be injected into the interior of the sealing tube 10.

[0044] Furthermore, after the air pump 2 stops working, the air pressure in the chamber between the connecting cap 3 and the sealing plate 14 drops to the same as the external air pressure. Under the action of the return spring 20 and the high-pressure air inside the conduit 11, one end of the sealing plate 14 fits with the sealing ring 15 again, which is beneficial to sealing the air inlet end of the air pipe 13 and preventing pressure relief inside the sealing tube 10 after the connecting cap 3 and the air pipe 13 are separated.

[0045] Example 2

[0046] See also Figure 1-7 , further improvements made on the basis of Example 1:

[0047] The control component also includes a U-shaped plate 21 and an extrusion rod 17. The U-shaped plate 21 is arranged on the outside of the air pipe 13, and the two sides of the inner cavity of the U-shaped plate 21 are rotatably connected to the outer wall of the air pipe 13 through a rotating shaft. A guide tube 22 is fixedly installed at one end of the U-shaped plate 21 away from the air pipe 13. The extrusion rod 17 is elastically installed in the inner cavity of the guide tube 22, and both ends of the extrusion rod 17 extend to the outside of the guide tube 22. When it is necessary to relieve the pressure inside the sealing tube 10, the U-shaped plate 21 is rotated until the middle of one end of the extrusion rod 17 and the middle of the air inlet end of the air pipe 13 are on the same horizontal line and overlap, and then the extrusion rod 17 is pressed to allow one end of the extrusion rod 17 to apply pressure to the outer wall of the sealing plate 14 through the air inlet end of the air pipe 13, so that the sealing plate 14 and the sealing ring 15 are separated. At this time, the pressure inside the sealing tube 10 and the conduit 11 is quickly relieved, which is conducive to improving the convenience of resetting the winding plate 5.

[0048] Furthermore, the distance between one end of the extrusion rod 17 of the air pipe 13 and the outer wall of the guide tube 22 is much greater than the distance between the air inlet end of the air pipe 13 and the sealing plate 14 , which is conducive to using the extrusion rod 17 to pressurize the sealing plate 14 .

[0049] An extrusion spring 23 is fixedly sleeved on the outer wall of the extrusion rod 17, and one end of the extrusion spring 23 is fixedly connected to the inner wall of the guide tube 22, wherein the extrusion spring 23 can apply a thrust to the extrusion rod 17 to continuously slide away from the sealing plate 14. After the pressing force on one end of the extrusion rod 17 is removed, the extrusion spring 23 allows the extrusion rod 17 to quickly reset and quickly withdraw from the inside of the gas pipe 13, which is beneficial to the repeated rotation of the U-shaped plate 21.

[0050] Guide slides 8 are symmetrically installed on both sides adjacent to the vertical plate 1 and the positioning ring. A driving threaded rod 7 is rotatably installed in the inner cavity of the guide slide 8. A sliding block is installed on the outer wall of the driving threaded rod 7 through threaded cooperation. An extrusion roller 6 for extruding the steel wire is elastically installed on the side of the sliding block close to the open end of the guide track. When the steel wire is being wound, the two driving threaded rods 7 are rotated to move the sliding block toward the mounting ring 12 until the outer wall of the extrusion roller 6 fits the outer wall of the steel wire ring, thereby applying pressure to the outside of the steel wire ring to prevent the steel wire ring from warping when it is wound.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
