Description

Technical Field

[0001] This utility model relates to the field of tire triangular rubber bonding technology, specifically an adaptive tire rubber core bonding and flipping mechanism. Background Technology

[0002] The original tire bead compounding production line consists of four production units: triangular core extrusion, cooling, material storage, and compounding, arranged in a segmented layout. Its temperature control device and electrical control cabinet are located at a high level, on the second floor. The equipment is first installed and debugged in the factory to confirm normal production. Afterward, the ground anchor bolts are removed, and the equipment is disassembled into four unit modules, along with components such as the power distribution cabinet and temperature control device. These are then packaged and transported separately to the tire manufacturing plant. Upon arrival, the equipment is positioned and installed according to the installation drawings, the anchor bolts are secured, and the external power supply, compressed air, and cooling water circulation systems are connected. A comprehensive debugging process is then conducted again until the production quality requirements are met.

[0003] The triangular rubber bonding section of the current original tire bead bonding production line has poor equipment adaptability due to factors such as the height of the triangular rubber core, the inner diameter of the steel wire ring, and the length of the material storage. One machine can only meet the needs of some product specifications. When different specifications of products need to be produced, disassembly, reinstallation, and debugging are required, which is labor-intensive, complicated, time-consuming, and costly.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figures 1 to 3 This utility model provides a technical solution:

[0025] An adaptive tire core bonding and flipping mechanism includes:

[0026] The bonding disc 1 has three disc petals 101. The lower end face of the bonding disc 1 is fixedly connected to the top of the bonding disc mounting base 5. The lower end face of the bonding disc mounting base 5 is provided with a bonding disc base 6. A pneumatic gripper 601 is provided on the bonding disc base 6. The gripper of the pneumatic gripper 601 is inserted into the claw hole 102 opened on the disc petals 101 of the bonding disc 1.

[0027] The gripper of the pneumatic gripper 601 is activated when the steel wire ring is installed on the mating disc 1, and expands the three disc petals 101 outward to fix the steel wire ring.

[0028] In this embodiment, the bonding disc 1 adopts a three-lobed fan-shaped technology. The bonding disc 1 is connected to a bonding disc mounting base 5 and a bonding disc base 6 at its lower part. The bonding disc base 6 is an adjustable eccentric base, and integrates three sets of pneumatic grippers 601. The gripper ends of the pneumatic grippers 601 are inserted into the claw holes 102 on the disc lobes 101 of the bonding disc 1. When installing the steel wire ring on the upper surface of the bonding disc 1, the operator can input data such as the size of the steel wire ring into an external controller, activating the pneumatic grippers 601 inside the bonding disc base 6. Compressed air enters the driving mechanism of the pneumatic grippers 601. The cavity pushes the three grippers to move outward synchronously along the path opened on the base. As the grippers continue to expand outward, the three-lobed disc 101 is subjected to uniform radial thrust and expands outward synchronously with the center of the bonding disc 1 as the reference. The upper arc surface of the three-lobed disc 101 is in close contact with the inner wall of the wire ring. Through mechanical tightening, a uniform circumferential force is applied to the wire ring, achieving precise positioning of the wire ring. This makes the bonding disc 1 suitable for the production needs of all specifications of semi-steel radial tires from 12 inches to 24 inches. Furthermore, when the bonding disc 1 is rotated and flipped to apply adhesive, the three-lobed disc 101 effectively prevents the wire ring from shaking.

[0029] Specifically, the pneumatic gripper 601 is connected to an air source through an air circuit system in the prior art.

[0030] Specifically, a guide rod cylinder 9 is fixedly connected to the lower end face of the bonding plate 1, and a pressure plate 8 is fixedly connected to the output end of the guide rod cylinder 9. The pressing surface of the pressure plate 8 is in contact with the upper end face of the bonding plate 1.

[0031] Specifically, the guide rod cylinder 9 is a pneumatic actuator that uses a cylinder piston to drive a guide rod to move, thereby achieving linear reciprocating motion, and utilizes the guide rod's guiding function to improve motion stability and positioning accuracy.

[0032] In this embodiment, the shape of the pressure plate 8 is as follows: Figure 2 As shown, the lower end of the pressure plate 8 is fixedly connected to the output end of the guide rod cylinder 9. The upper end of the pressure plate 8 has a bent arc surface, so that the lower pressing surface of the pressure plate 8 is in contact with the upper end surface of the bonding plate 1. The feeding assembly 13 delivers the triangular glue to the side near the bonding plate 1 and the glue clamping and swinging assembly 12. The finger-shaped cylinder 1202 on the glue clamping and swinging assembly 12 cooperates with the swing cylinder to clamp the triangular glue onto the steel wire ring positioned on the bonding plate 1. The guide rod cylinder 9 is activated, driving the pressure plate 8 to press down, clamping and pressing the triangular glue and bonding it to the steel wire ring. When the bonding plate 1 rotates and flips to apply glue, the guide rod cylinder 9 and the pressure plate 8 press down on the triangular glue head and cooperate with the flipping action to complete the glue application.

[0033] Specifically, a cylinder mounting base 3 is fixedly connected to the lower end face of the bonding plate 1, and an ejection cylinder 7 is fixedly connected to the lower end of the cylinder mounting base 3.

[0034] Specifically, the output end of the ejector cylinder 7 passes through the disc 101 of the bonding disc 1 to reach the other side, and an ejector block 2 is fixedly connected to the top of the output end of the ejector cylinder 7 for ejecting the wire ring after bonding is completed.

[0035] In this embodiment, after bonding is completed, the pneumatic gripper 601 of the bonding disc base 6 drives the disc 101 to reset and release the positioning of the wire ring, the ejector cylinder 7 is started, and the ejector block 2 at the output end ejects the wire ring for easy material removal.

[0036] Specifically, an anti-stick plate 4 is fixedly connected to the upper surface of the bonding plate 1.

[0037] Example 2:

[0038] Please see Figures 4 to 5 This utility model provides a technical solution:

[0039] Specifically, the lower end face of the fitting plate base 6 is rotatably connected to the top of the rotating assembly 11, and the rotating assembly 11 is fixedly connected inside the mounting frame 10.

[0040] In this embodiment, the bonding disc 1 is installed on the tire triangular rubber core bonding machine. The feeding assembly 13, the rubber clamping and swinging assembly 12, the rotating assembly 11, and the mounting frame 10 are other parts of the bonding machine, all of which preferably utilize existing technologies. This embodiment only provides a simple functional description. For example, the feeding assembly 13 is mainly a multi-roller structure used to convey the triangular rubber to the rubber clamping and swinging assembly 12. A swing cylinder is fixedly connected to the front end of the feeding assembly 13. After bonding is completed, the swing cylinder swings the triangular rubber to the trimming cutter position. The trimming cutter then moves the triangular rubber... The head is cut to prepare for the next cycle; the main structure of the adhesive clamping and grouting assembly 12 is a finger-shaped cylinder 1202. The top of the gripper part of the finger-shaped cylinder 1202 is connected to a pressure block 1201, which is used to press the triangular adhesive on the steel wire ring; the mounting frame 10 mainly includes a rotating assembly 11. The bottom of the rotating assembly 11 is driven to rotate by a worm gear reducer and is fixed to the base with a bracket. The reducer drives the bonding disc 1 to rotate to complete the adhesive application. The mounting frame 10 is also equipped with two sets of pressure rollers, which are used to press the triangular adhesive onto the steel wire ring when the bonding disc 1 rotates.

[0041] In use, the steel wire ring is first manually placed onto the bonding disc 1. The pneumatic gripper 601 of the bonding disc base 6 is activated, and the grippers insert into the claw holes 102 of the three disc segments 101 of the bonding disc 1 and expand outwards, positioning the steel wire ring through the expansion of the three disc segments 101. Then, the feeding assembly 13 delivers triangular adhesive to the steel wire ring, which is placed onto the steel wire ring by the finger cylinder 1202. The guide rod cylinder 9 at the lower end of the bonding disc 1 drives the pressure plate 8 to press down, engaging with the upper surface of the bonding disc 1 to press the triangular adhesive. Simultaneously, the bonding disc 1 is driven by the rotating assembly 11, causing the steel wire ring and triangular adhesive to rotate synchronously. The mounting frame 10 is fixed with... Two sets of pressure rollers gradually press the triangular adhesive onto the steel wire ring; after the motor of the rotating component 11 precisely controls the bonding disc 1 to rotate to a fixed length, the finger-shaped cylinder 1202 pulls the triangular adhesive to the front end of the feeding component 13 to complete the cutting. At this time, the pneumatic gripper 601 on the bonding disc base 6 drives the disc 101 to reset. The rotating component 11 continues to drive the bonding disc 1 to rotate a small step to achieve bonding. The cut joint is pressed firmly by the two pressure rollers. After bonding is completed, the ejector cylinder 7 is pneumatically started. The ejector block 2 at its output end passes through the disc 101 from below and ejects the steel wire ring out of the bonding disc 1, so that the steel wire ring can be removed.

[0042] All other parts of this utility model not described herein are the same as existing technologies, or are known technologies, or can be implemented using existing technologies, and will not be described in detail here.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
