Description

Technical Field

[0001] This utility model relates to the field of tire processing technology, and more specifically, to a lettering and positioning mechanism for tire processing. Background Technology

[0002] The tire engraving positioning mechanism is the core equipment for ensuring the accuracy of tire engraving. It mainly consists of four parts: positioning components, drive system, and control system. During operation, the control system drives and adjusts the size of the positioning fixture according to the control parameters. After the tire is transported to the workstation, the control system drives the positioning fixture to move towards the tire and automatically clamp and fix it. The tire is clamped and positioned after it moves to the engraving workstation. After the external engraving equipment finishes engraving, the fixture is automatically released and the tire is transported to the next process for subsequent processing. Since the tire's positioning position directly affects the subsequent engraving position, it is necessary to center the tire.

[0003] In related technologies, during the use of positioning mechanisms, clamping and positioning forces are generally applied to the tire through a movable clamping plate or clamping rod to perform clamping and positioning work, thereby enabling its use.

[0004] However, in the current use of positioning mechanisms, because the tire is circular, when clamping the tire with a clamping plate or rod, the tire positioning and clamping position is very prone to shift, which leads to the subsequent tire marking position shifting, affecting the positioning mechanism's ability to center the tire and the clamping and positioning effect.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Reference Figures 1-4This utility model provides a technical solution: a lettering and positioning mechanism for tire processing, including a base 1 and a positioning guide mechanism. A bracket 2 is installed on the top of the base 1, and supports 3 are fixedly connected to both sides of the bottom of the base 1. The bracket 2 can form a medium for clamping, positioning and centering the external tire workpiece on the top of the bracket 2, so that the bracket 2 can clamp and center the external tire, avoiding the tire positioning and clamping position deviation, which would cause the subsequent lettering position deviation on the tire. Therefore, the centering effect and clamping and positioning effect of the bracket 2 on the tire are improved.

[0021] Reference Figures 1-4 In a preferred embodiment, the positioning and guiding mechanism includes a positioning frame 4, which is movably connected to both sides of the top of the support 2. A guide frame 5 is inserted and installed on the top of the positioning frame 4. A connection port 6 is opened on both sides of the bottom of the positioning frame 4. A connecting rail 7 located inside the connection port 6 is fixedly connected to both sides of the top of the support 2. The positioning connection mechanism is fixedly connected to the inside of the positioning frame 4. The positioning frame 4 drives the guide frame 5 to move inward. At this time, the connecting rail 7 moves inside the connection port 6, performing a translational connection between the positioning frame 4 and the support 2, so that the guide frame 5 contacts the tires conveyed by the external conveying equipment to the engraving station. Since the guide frame 5 is V-shaped, As the guide frame 5 contacts the tire, the guide frame 5 uses its inner inclined guide to center and clamp the tire. The positioning connection mechanism includes a connector 8, a connecting rod 9, and a connecting arm 10. The connector 8 is fixedly connected to the inner side of the positioning frame 4, the connecting rod 9 is movably connected to the top of the connector 8 via a pin, and the connecting arm 10 is movably connected to the bottom of the connecting rod 9 via a pin. This allows for clamping and positioning connections between the positioning frames 4, enabling the positioning frames 4 to move the guide frame 5 synchronously to clamp and position the external tire workpiece. This avoids difficulties in synchronizing the connection of the positioning frames 4 during use, thus improving the synchronization effect between the positioning frames 4.

[0022] Reference Figures 2-3 In a preferred embodiment, a servo motor 11 is fixedly connected to the bottom of the bracket 2, and the output end of the servo motor 11 is connected to the bottom of the connecting arm 10. A control box 12 is installed on the left side of the top of the base 1. The servo motor 11 is electrically connected to the control box 12 through a wire, which can provide the connecting arm 10 with the power to drive the connecting rod 9 to move the positioning frame 4. This avoids the situation where the connecting arm 10 is difficult to drive the positioning frame 4 through the connecting rod 9 when it is working, thus improving the driving effect of the connecting arm 10. Lifting grooves 13 are provided on both sides of the bottom of the bracket 2. Lifting plates 14 are movably connected inside the lifting grooves 13. The bottom of the lifting plates 14 is fixedly connected to the top of the base 1, which can perform lifting and lowering connection between the bracket 2 and the base 1. This avoids the situation where the bracket 2 is difficult to adjust when it is in use, thus improving the flexibility of the bracket 2.

[0023] Reference Figures 2-4 In a preferred embodiment, a positioning sleeve 15, which communicates with the lifting groove 13, is fixedly connected to the bottom of the inner side of the bracket 2. Positioning rods 16 are movably connected to both sides inside the positioning sleeve 15. This allows for the insertion and positioning of the adjusted bracket 2 and the lifting plate 14, avoiding the situation where the bracket 2 is difficult to position with the lifting plate 14 after adjustment. Therefore, the positioning convenience of the bracket 2 and the lifting plate 14 is improved. The inner side of the lifting plate 14 is provided with a positioning hole 17 that communicates with the positioning sleeve 15. The outer side of the positioning rod 16 is located inside the positioning hole 17, which can provide multiple insertion and positioning spaces for the positioning rod 16. This avoids the situation where the positioning rod 16 is difficult to meet the insertion and positioning requirements of the bracket 2 and the lifting plate 14 when in use, thus improving the insertion and positioning flexibility of the positioning rod 16.

[0024] Reference Figures 2-4 In a preferred embodiment, push grooves 18 are provided on both sides of the inner wall of the positioning sleeve 15, and springs 19 are provided on both sides inside the positioning sleeve 15. One end of the spring 19 is connected to the inner wall of the push groove 18, and the other end of the spring 19 is connected to the surface of the positioning rod 16. This can apply an outward pushing force to the positioning rod 16, preventing the positioning rod 16 from disengaging from the positioning hole 17 during operation, thus improving the working stability of the positioning rod 16. A moving opening 20 is provided on the outer side of the front side of the positioning sleeve 15, and a moving rod 21 is movably connected inside the moving opening 20. The rear side of the moving rod 21 is fixedly connected to the front side of the positioning rod 16, providing the user with an operating medium to move the positioning rod 16, preventing the positioning rod 16 from being difficult to move during use, thus improving the ease of operation of the positioning rod 16.

[0025] Specifically, the working process or principle of this tire processing lettering positioning mechanism is as follows: During use, the bracket 2 is moved to the bottom of the external roller conveyor for transporting tire workpieces through the cooperation of the base 1 and the support 3. According to the actual height of the external roller conveyor, hold the moving rod 21 and move the positioning rod 16 inward through the moving port 20 to disengage from the positioning hole 17, and make the positioning rod 16 enter the positioning sleeve 15. At this time, the spring 19 contracts into the push groove 18 under the influence of the inward moving force of the positioning rod 16, preparing for applying an outward thrust to the positioning rod 16 subsequently. Then, move the bracket 2 upward by moving the moving rod 21 in cooperation with the positioning rod 16 and the positioning sleeve 15 to move the positioning frame 4 upward, so that the top of the positioning frame 4 penetrates through the gap between the rollers of the external roller conveyor. At this time, the lifting plate 14 moves within the lifting groove 13 to perform the lifting and adjustment connection work between the bracket 2 and the base 1. After the bracket 2 is adjusted and lifted, hold the moving rod 21 and move it outward into the positioning hole 17, so that the positioning rod 16 cooperates with the positioning sleeve 15 and the positioning hole 17 to perform the plug-in positioning work between the adjusted and lifted bracket 2 and the lifting plate 14. At this time, the contracted spring 19 applies an outward thrust to the positioning rod 16 to ensure the plug-in positioning effect of the positioning rod 16 and ensure the working height of the bracket 2 and the positioning frame 4. Subsequently, hold the guiding frame 5 and plug it onto the top of the positioning frame 4 and the external roller conveyor, preparing for subsequent clamping and guiding of the external tire. Electrically connect the control box 12 and the external power supply through a wire, preparing for the subsequent operation of the control box 12 and the servo motor 11. It should be noted that the control box 12 can be connected to the central control systems of the external lettering equipment and the roller conveyor for linkage control work. When the external roller conveyor transports the tire workpiece to the lettering station of the lettering equipment, the control box 12 starts the servo motor 11 to apply a rotational force to the connecting arm 10. The connecting arm 10 rotates to drive the connecting rod 9 to tilt and flip, so that the connecting arm 10 cooperates with the connecting rod 9 and the connecting head 8 to apply a driving force for moving inward to the positioning frame 4, causing the positioning frame 4 to move and contact the tire workpiece with the guiding frame 5. At this time, the connecting rail 7 moves within the connecting port 6 to perform the translation connection and anti-offset work between the positioning frame 4 and the bracket 2. Since the guiding frame

[0026] It should be noted that the servo motor 11 and the control box 12 are both devices or equipment existing in the prior art, or devices or equipment that can be realized by the prior art. Their power supply, specific composition, and principle are clear to those skilled in the art, so they will not be described in detail here.
