An automatic rubber tire tread bonding device

Abstract

This utility model discloses an automatic rubber tire tread bonding device, including a base and a rolling mechanism, a robotic arm, and a bonding machine mounted on the base. The rolling mechanism includes a support plate, a drive motor, and an inner support member. The bottom of the support plate is fixedly connected to the base, and the drive motor is mounted on the support plate to provide stable and continuous rotational power to the inner support member. This utility model separates the inner support member from the tread bead by contracting inwards, allowing the robotic arm to smoothly move the tread bead away. The robotic arm then moves the tread bead concentrically onto the outside of the tire blank. The bonding machine then compresses and contracts the tire blank, causing it to expand outwards to form a tire shape. While expanding outwards, it avoids gradually contacting and bonding with the inside of the tread bead. This allows the device to have more flexible size adjustment compared to a forming device, enabling the bonding equipment to directly adapt to tire tread bonding operations of different sizes, reducing costs while increasing overall efficiency.

Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, and more specifically, to an automatic rubber tire tread bonding device. Background Technology

[0002] Automatic tire tread bonding involves fixing a pre-rolled tire blank, then using a winding structure to take the outer ring of the tread material to the required size, and then using a gripping mechanism to grasp and move the rolled-up tread material to the outside of the tire blank 6, keeping the two in a concentric position. The bonding device then tightens and squeezes the tire blank, causing it to bulge in the middle to form a preliminary tire shape. The bulged part is bonded to the inner ring of the tread ring, and then the next process is carried out to complete the tire tread bonding.

[0003] Currently, due to the different sizes and specifications of tires, the winding and coiling structure can generally only produce tires of a single size. A single bonding device is needed to produce tires of different sizes, and different winding and coiling devices need to be matched and replaced, which increases costs and reduces overall production efficiency. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide an automatic rubber tire tread bonding device to solve the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution;

[0006] An automatic rubber tire tread bonding device includes a base and a winding mechanism, a robot arm, and a bonding machine mounted on the base. The winding mechanism includes a support plate, a drive motor, and an inner support member. The bottom of the support plate is fixedly connected to the base. The drive motor is mounted on the support plate to provide stable and continuous rotational power to the inner support member. The inner support member winds up tread material supplied from an external conveyor belt to form a loop. A linear reciprocating guide rail is mounted on the top of the base. The robot arm is mounted on the linear reciprocating guide rail and grasps the looped tread material on the inner support member. A tire blank is mounted on the bonding machine. The bonding machine shrinks and compresses the tire blank to form a shape, and the bonding machine expands the exterior of the tire blank to bond it with the tread grasped by the robot arm. A PLC controller is mounted on the bonding machine to control the coordinated operation of the winding mechanism, the robot arm, and the bonding machine.

[0007] As a further description of the above technical solution: the inner support includes a rotating block, a positioning ring, a telescopic member, and annularly distributed outer support blocks. One end of the rotating block is rotatably connected to the support plate. The output end of the drive motor is fixedly connected to the rotating block through a coupling. The telescopic member is installed inside the rotating block and is connected and engaged with the inner end of the outer support block. The outer end of the outer support block passes through and is slidably connected to the outer side of the positioning ring. One side of the positioning ring is fixedly connected to the rotating block through a diagonal rod.

[0008] As a further description of the above technical solution: the telescopic component includes a horizontal cylinder, a movable disk, and annularly distributed hinge rods. The horizontal cylinder is fixedly installed inside the rotating block, and the movable end of the horizontal cylinder is fixedly connected to the movable disk. The movable disk is movably connected to the outer support block via the hinge rods.

[0009] As a further description of the above technical solution: a sealing plate is installed on the right side of the inside of the positioning ring, and the sealing plate is located on the right side of the moving disk.

[0010] As a further description of the above technical solution: a buffer contact block aligned with the movable disk is fixedly installed at the center of the left side of the sealing plate.

[0011] As a further description of the above technical solution: the robotic arm includes a support frame and four pneumatic grippers arranged in a cross shape. The bottom of the support frame is mounted on a linear reciprocating guide rail. The four pneumatic grippers are arranged in a ring on the support frame, and the gripping section of the pneumatic grippers has an arc shape.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] This solution utilizes an inner support component to flexibly adjust the outer ring support size through a winding mechanism, allowing it to adapt flexibly to the winding operation of tire tread rings of different sizes. This enables the device to have more flexible size adjustment of the ring forming equipment, allowing the bonding equipment to directly adapt to tire tread bonding operations of different sizes, reducing costs while increasing overall efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0021] Please see Figure 1-4 This utility model discloses an automatic rubber tire tread bonding device, comprising a base 1 and a winding mechanism 2, a robotic arm 3, and a bonding machine 4 mounted on the base 1. The winding mechanism 2 includes a support plate 21, a drive motor 22, and an inner support member 23. The bottom of the support plate 21 is fixedly connected to the base 1. The drive motor 22 is mounted on the support plate 21 to provide stable and continuous rotational power to the inner support member 23. The inner support member 23 winds up the tread material supplied from an external conveyor belt to form a loop. A linear reciprocating guide rail 5 is mounted on the top of the base 1, and the robotic arm 3 is mounted on the linear reciprocating guide rail 5. On the reciprocating guide rail 5, the robotic arm 3 grasps the tread ring formed on the inner support 23. The laminating machine 4 is equipped with a tire blank 6. The robotic arm 3 moves the grasped tread ring to the outside of the tire blank 6. The laminating machine 4 shrinks and squeezes the tire blank 6 to form it. The laminating machine 4 also expands the outside of the tire blank 6 and makes it fit with the tread grasped by the robotic arm 3. The laminating machine 4 is equipped with a PLC controller 7 for controlling the coordinated operation of the rolling mechanism 2, the robotic arm 3 and the laminating machine 4. In this case, the connection method between the PLC controller 7 and the specific execution power unit can be signal or electrical connection, which will not be elaborated.

[0022] In this invention, the tire tread size parameters are generated by the PLC controller 7 using preset equipment. First, the PLC controller 7 is activated to control the drive motor 22 to rotate the inner support member 23. Simultaneously, the inner support member 23 automatically adjusts to the set tread size. Then, the external conveying mechanism transports the tread base material to the outside of the inner support member 23. As the inner support member 23 rotates, the tread forms a tread. Then, the PLC controller 7 activates the linear reciprocating guide rail 5 to move the robot arm 3 to the outside of the tread bead and clamp it from the outside. At this time, the inner support member 23 retracts inward and separates from the tread bead, allowing the robot arm 3 to smoothly move the tread bead away from it. Then, the robot arm 3 moves the tread bead concentrically onto the outside of the tire blank 6. Then, the bonding machine 4 is started to shrink and compress the tire blank 6, causing it to shrink and expand outward to form a tire shape. As it expands outward, its outer surface gradually contacts and adheres to the inside of the tread bead. This allows the device to have more flexible size adjustment of the coiling equipment, enabling the bonding equipment to directly adapt to tire tread bonding operations of different sizes. This reduces costs and increases overall efficiency. It solves the problem in the existing technology that, due to different tire sizes, the coiling structure can generally only produce a single size specification. When a single bonding device produces tires of different sizes, it is necessary to match and replace different coiling devices, which increases costs and reduces overall production efficiency.

[0023] Please see Figure 2 and Figure 3 The inner support 23 includes a rotating block 231, a positioning ring 232, a telescopic member 233, and an annularly distributed outer support block 234. One end of the rotating block 231 is rotatably connected to the support plate 21. The output end of the drive motor 22 is fixedly connected to the rotating block 231 through a coupling. The telescopic member 233 is installed inside the rotating block 231 and is connected to the inner end of the outer support block 234. The outer end of the outer support block 234 passes through and slides to the outer side of the positioning ring 232. One side of the positioning ring 232 is fixedly connected to the rotating block 231 through a diagonal rod.

[0024] In this invention, the rotating block 231 and the positioning ring 232 are connected as a whole, so that when the drive motor 22 drives the rotating block 231 to rotate, the positioning ring 232 rotates synchronously and as a whole, resulting in a stable structure. At the same time, the telescopic component 233 is used to adjust the length of the outer support block 234 extending out of the positioning ring 232, thereby adjusting the outer diameter of the outer circle formed by the outer ends of the outer support block 234, so as to achieve the adaptation and adjustment of tread rings of different sizes, which is more flexible and efficient.

[0025] Please see Figure 3The telescopic component 233 includes a horizontal cylinder 2331, a movable disk 2332, and a ring-shaped hinge rod 2333. The horizontal cylinder 2331 is fixedly installed inside the rotating block 231. The movable end of the horizontal cylinder 2331 is fixedly connected to the movable disk 2332. The movable disk 2332 is movably connected to the outer support block 234 via the hinge rod 2333.

[0026] In this invention, the horizontal cylinder 2331 is activated to drive the moving disk 2332 to translate, thereby changing the connection and support angle between the disk and the hinge rod 2333, and thus changing the support angle between the outer end of the hinge rod 2333 and the outer support block 234, thereby changing the outward extension length of the outer support block 234, so as to realize the diameter adjustment of the entire tread ring support circle, which is efficient and flexible.

[0027] Please see Figure 3 The positioning ring 232 has a sealing plate 2321 installed on the right side inside, and the sealing plate 2321 is located on the right side of the moving disk 2332.

[0028] In this invention, the sealing plate 2321 limits the forward movement of the moving disk 2332, preventing excessive movement and keeping the adjustment within a reasonable range.

[0029] Please see Figure 3 Among them, a buffer contact block 2322 aligned with the movable disk 2332 is fixedly installed at the center of the left side of the sealing plate 2321.

[0030] In this invention, the buffer contact block 2322 on the sealing plate 2321 buffers the movement contact of the moving disk 2332, protecting the internal structure and improving the service life of the device.

[0031] Please see Figure 1 and Figure 4 The robotic arm 3 includes a support frame 31 and four cross-shaped pneumatic grippers 32. The bottom of the support frame 31 is mounted on a linear reciprocating guide rail 5. The four pneumatic grippers 32 are arranged in a ring on the support frame 31. The gripping section of the pneumatic grippers 32 has an arc shape.

[0032] In this invention, four cross-shaped pneumatic grippers 32 on the support frame 31 achieve a ring gripping of the outer side of the tire tread bead, making the gripping size more flexible and the stability better.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
