Description

Technical Field

[0001] This invention relates to the field of tire forming technology, specifically to a zero-degree joint detection device and forming machine for an all-steel radial tire forming machine. Background Technology

[0002] Currently, common structures for all-steel radial tires include two-ply, three-ply, "3+0", four-ply, and "4+0" structures. The "3+0" and "4+0" structures, with the addition of a zero-degree belt layer, effectively improve tire rigidity and durability. In tire production, the zero-degree belt layer, as a steel wire component, requires an overlapping joint, with only one possible joint. The angle of the steel wires must be parallel to the feeding template conveyor belt. During material feeding, the joint position needs to be manually overlapped and conveyed, unlike the standard belt layer butt joint. If operators fail to detect this in time, two zero-degree joints will exist in one tire, failing to meet our product standards and process requirements, resulting in defective products.

[0003] The disadvantages of existing technology: The existing zero-degree belt layer feeding system does not have the function of identifying the joint position. It is impossible to accurately identify the joint position from the equipment. When the operator cannot find the joint in time and feed the material normally, it will result in two zero-degree joints on one tire, which does not meet the product design requirements and standards and produces unqualified products.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a zero-degree joint detection device and forming machine for all-steel radial tire forming machines, so as to overcome the shortcomings in current practical applications. Summary of the Invention

If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0026] The present invention provides the following embodiments.

[0027] Example 1

[0028] This invention provides a zero-degree joint detection device for an all-steel radial tire forming machine, such as... Figure 1-2 As shown, the zero-degree joint detection device includes: a support assembly, which is connected to the outside of the feeding template 8 of the all-steel radial tire forming machine, and the detection assembly is connected to the support assembly.

[0029] The beneficial effects of the above technical solution are as follows: This invention, by setting up a zero-degree joint detection device, uses the operation of the all-steel radial tire forming machine to drive the zero-degree belt layer, and then uses the zero-degree joint detection device to detect the material joint, thereby realizing the detection of the zero-degree belt layer. This improves upon the problem raised in the background technology: existing zero-degree belt layer feeding systems lack joint position identification functionality, making it impossible to accurately identify the joint position from the equipment perspective; when operators fail to detect the joint in time and supply material normally, it can lead to two zero-degree joints on one tire, failing to meet product design requirements and standards, and resulting in defective products.

[0030] Example 2

[0031] Based on Example 1, such as Figure 2 As shown, the support assembly includes two connecting rods 9, which are arranged on the front and rear sides of the feeding template 8. The feeding direction of the feeding template 8 is left and right, and a linear guide rail 10 is fixedly installed between the connecting rods 9. A detection assembly is connected to the linear guide rail 10.

[0032] Optionally, the detection component includes: a zero-degree joint detection switch 11, a plurality of zero-degree joint detection switches 11 being slidably connected to the linear guide rail 10, and the bottom ends of the plurality of zero-degree joint detection switches 11 being connected to the limit detection joint 12.

[0033] Optionally, a light assembly is provided at the bottom of the zero-degree connector detection switch 11.

[0034] Optionally, the limit detection connector 12 includes: a sensor for detecting changes in the thickness or position of the zero-degree belt layer 5; a signal input system for transmitting the signal detected by the sensor to the control system for corresponding operations; a first control system for receiving signals from the signal input system and controlling the HMI interface to alarm; and a monitoring device for observing and confirming the status of the limit detection connector 12, thereby enabling timely replacement and maintenance of the limit detection connector 12.

[0035] Optionally, the two zero-degree joint detection switches 11 are controlled by servo motors to move back and forth on the linear guide rail 10, and each of the two zero-degree joint detection switches 11 is equipped with a light assembly at its bottom.

[0036] Optionally, the lighting assembly includes: a light source, which may be an LED light, laser, etc., for providing light illumination to the zero-degree bandgap layer 5; a sensor, which may be a camera, for capturing reflected, transmitted, or scattered light signals; a second control system, which receives the light signals captured by the sensor, processes and analyzes them, runs the corresponding algorithm (determines the position of the target component through image processing, edge detection, pattern matching, etc., based on the characteristics of the light signal and preset rules), and controls the servo motor to start, driving the two zero-degree joint detection switches 11 to move on the linear guide rail 10 to achieve the front and rear positioning of the zero-degree joint detection switches 11; and a feedback device, which provides feedback information to the staff through indicator lights, displays, sounds, etc., based on the positioning information output by the second control system.

[0037] The working principle of the above technical solution is as follows: The zero-degree belt layer 5 is fed from the feeding car 7 to the guide device 6 and then to the rear feeding template 1 8. The zero-degree belt layer 5 passes through the zero-degree joint detection device 4. The thickness change of the zero-degree belt layer 5 triggers the limit detection of the joint 12, inputs a signal, and causes an alarm on the HMI interface to remind the staff to confirm the joint. Then, the joint part is pushed forward by the floating roller 3 and the front feeding template 2. After the joint is cleared, the zero-degree normal operation of bonding to the BT drum 1 begins. When it is necessary to adjust the front and rear positions of the two zero-degree joint detection switches 11, the positioning is achieved by the positioning of the light positioning component and the start of the servo motor, which drives the two zero-degree joint detection switches 11 to move on the linear guide rail 10 to achieve the front and rear movement positioning of the zero-degree joint detection switches 11.

[0038] The beneficial effects of the above technical solution are as follows: By adding a zero-degree joint detection device 4 to the zero-degree feeding template 8 of the all-steel radial tire forming machine, it is beneficial to trigger an alarm when the joint passes by, prompt the HMI human-machine interface for confirmation, and production can only continue after confirmation and reset; by controlling the servo motor and positioning the zero-degree joint detection position 4 according to the lighting component, the corresponding parameters are set so that the two zero-degree joint detection switches 11 can move left and right on the linear guide rail 10 according to the parameter settings, thereby meeting the production needs of different specifications and quickly adjusting the position, which is very convenient and practical.

("BT drum" usually refers to "Building Tire Drum," also known as the tire barrel. It is an important component in the tire forming process, used to assemble and press the various layers of the tire (such as the carcass, belts, etc.) according to a predetermined structure and shape to form the final tire product. The design and operation of the "BT drum" have a significant impact on the quality and performance of the tire.)

[0041] Optionally, the zero-degree belt layer 5 is delivered from the guide device 6 to the rear feeding template 8 by the feeding vehicle 7.

[0042] Optionally, the feeding template 8 is conveyed from right to left. A rolling device 38 is installed at the top of the feeding template 8, located to the right of the zero-degree joint detection device. The rolling device 38 includes a drive motor 13, which is fixedly installed inside the housing 20. The output shaft of the drive motor 13 is fixedly installed at one end of a rotating shaft 14. A bevel gear 15 is fixedly installed at the other end of the rotating shaft 14. A second bevel gear 22 meshes with the first bevel gear 15, and the top of the second bevel gear 22 is fixedly installed on a worm gear 23. The other end of the worm gear 23 is rotatably connected to the inner wall of the housing 20. The worm gear 23 meshes with a worm wheel 24, which is connected to the rolling mechanism. ， A pulley 16 is fixedly mounted on the shaft 14. The pulley 16 is connected to two sets of belt assemblies arranged symmetrically on the left and right sides via a belt 17.

[0043] Optionally, the rolling mechanism is symmetrically arranged at the left and right ends of the worm gear 24. The rolling mechanism includes: a connecting rod 25, which is fixedly connected to the worm gear 24, and the front and rear ends of the connecting rod 25 pass through the limiting rod 32 and are fixedly connected to the bevel gear 26. The top end of the limiting rod 32 is fixedly installed on the inner wall of the housing 20. The bevel gear 26 meshes with the bevel gear 27, and the right end of the bevel gear 27 is coaxially fixedly connected to the gear 28, which meshes with the rack 29. The bottom end of the rack 29 passes through the housing 20 and is fixedly connected to the frame 30, and a pressure roller 31 is rotatably connected inside the frame 30.

[0044] Optionally, the belt assembly includes: a second pulley 18, which is connected to a first pulley 16 via a belt 17, and the second pulley 18 is fixedly mounted on a second rotating shaft 19. One end of the second rotating shaft 19 is rotatably connected to the inner wall of the housing 20, and the other end of the second rotating shaft 19 is fixedly mounted with a winding wheel 21, which is connected to a guide mechanism.

[0045] Optionally, the guide mechanism is symmetrically arranged at the left and right ends of the housing 20. The guide mechanism includes: a connecting rope 33, one end of which is fixedly installed on the winding wheel 21, and the other end of which is fixedly installed on one end of the adjusting rod 34. The middle end of the adjusting rod 34 is hinged in the cavity 35 of the housing 20. A T-shaped guide rod 36 is fixedly installed on the other end of the adjusting rod 34. One end of the return spring 37 is fixedly installed on the bottom end of the adjusting rod 34 on the side away from the T-shaped guide rod 36, and the other end of the return spring 37 is fixedly installed on the inner wall of the cavity 35.

[0046] The working principle of the above technical solution is as follows: All-steel radial tires commonly use two-layer, three-layer, "3+0", four-layer, and "4+0" structures to add zero-degree belt layers 5. During the addition process, air will always remain between the layers, resulting in air bubbles being generated between the zero-degree belt layers 5. To expel these air bubbles, the user starts the drive motor 13. The drive motor 13 drives the bevel gear 15 and the pulley 16 coaxially fixed to it to rotate. The rotation of the bevel gear 15 drives the bevel gear 22 meshing with it to rotate as well. The rotation of the bevel gear 22 drives the worm gear 23 to rotate as well, which in turn drives the worm wheel 24 meshing with the worm gear 23 to rotate as well. The rotation of the worm wheel 24 drives the connecting rod 25 fixed to it to rotate as well. The connecting rod 25 further drives the bevel gear 26 and the pulley 26 meshing with the bevel gear 26 to rotate as well. The meshing bevel gear 4 27 rotates, which drives the coaxially rotating gear 3 28 to rotate as well. The rotation of gear 3 28 drives the meshing rack 29 to move downward, which in turn drives the frame 30 to move downward until the pressure roller 31 contacts the zero-degree belt layer 5. The rotation of pulley 1 16 drives the two pulleys 2 18 connected to its belt 17 to rotate clockwise. The rotation of pulley 2 18 drives the coaxially rotating winding wheel 21 to rotate as well. The rotation of winding wheel 21 drives the connecting rope 33 to wind. The contraction of the connecting rope 33 drives one end of the adjusting rod 34 hinged to the inner wall of the cavity 35 to move upward, thereby causing the T-shaped guide rod 36 fixedly installed at the other end of the adjusting rod 34 to move inward to both sides of the zero-degree belt layer 5 at both ends of the feeding template 1 8, thereby guiding it.

[0047] The beneficial effects of the above technical solution are as follows: By setting the rolling device 38, it is beneficial to squeeze out any air bubbles that may exist between the zero-degree belt layers 5 under the action of gravity, thereby expelling the gas in the bubbles and preventing the presence of air bubbles during tire molding, which could harm tire quality; by setting the rack 29 and the frame 30, it is beneficial to adjust the vertical position of the zero-degree belt layers 5 of different thicknesses by adjusting the drive motor 13 when rolling them; by setting the guiding mechanism, it is beneficial to limit the zero-degree belt layers 5 on both sides of the top of the feeding template 8, preventing... The zero-degree belt layer 5 is prevented from shifting during feeding, thus affecting the feeding process. By setting up the winding wheel 21 and the connecting rope 33, it is possible to adjust the angle of the adjusting rod 34 by controlling the contraction and relaxation of the connecting rope 33, thereby moving the T-shaped guide rod 36 to both ends of the feeding template 8, thus guiding the zero-degree belt layer 5. By setting up the drive motor 13, it is possible to realize the automatic operation of the device, thereby reducing the labor of workers, improving tire production efficiency, and further increasing the tire production qualification rate, which is very convenient and practical.
