Description

Technical Field

[0001] The utility model belongs to the technical field of tire production equipment, and particularly relates to an anti-bubble forming machine for tire production. Background Art

[0002] In a tire forming machine, components such as an inner liner, a tread cap, and a tire shoulder are generally sequentially bonded to a forming roller of the forming machine, and then a tire blank is formed under the action of an adhesive and a pressure roller. During the above-mentioned forming process, when the components are pressed together, air bubbles are likely to be generated, affecting the quality of the tire blank. The patent document with the publication number CN110065251B discloses a rubber strip pressure roller device for a new type of tire forming machine, which includes a workbench, a forming drum rotatably arranged on the workbench, a machine frame is arranged on one side perpendicular to the axis direction of the forming drum, a connecting plate is fixedly arranged at the top end of the machine frame, an adjusting cylinder is hinged on the upper surface of the connecting plate, the piston rod of the adjusting cylinder faces the side of the forming drum, the end of the piston rod of the adjusting cylinder is hinged with an adjusting frame, the adjusting frame is rotatably connected with the connecting plate, a walking cylinder is fixedly arranged at one end of the adjusting frame away from the adjusting cylinder, the moving direction of the walking cylinder is parallel to the rotation axis of the forming drum, a lifting cylinder is fixedly arranged on the walking cylinder, the piston rod of the lifting cylinder is vertically downward, and the bottom end of the piston rod of the lifting cylinder is rotatably connected with a pressure wheel. By making the rotation axis of the pressure wheel perpendicular to the rotation axis of the forming drum, the effect of improving the bonding quality of the rubber strip body is achieved. However, the pressure wheel presses the rubber strip on the forming drum in the horizontal direction (pressing at the joint of the tread cap), and cannot effectively press the joint between the tread cap and the tire shoulder, where air bubbles are most likely to be generated, which is not conducive to improving the quality of the tire. Therefore, an anti-bubble forming machine for tire production is needed to solve the above technical problems. Summary of the Utility Model

[0003] In view of the above defects existing in the prior art, the utility model provides an anti-bubble forming machine for tire production, which includes a machine frame and a forming roller arranged on the machine frame. The forming roller is matched with a material pressing mechanism. The material pressing mechanism includes two symmetrically arranged material pressing components on the left and right. Each material pressing component includes a mounting plate, a first telescopic rod, a first roller, and a second roller. The fixed end of the first telescopic rod is connected with the machine frame, and the telescopic end of the first telescopic rod is connected with the mounting plate. The first roller and the second roller are respectively arranged at both ends of the mounting plate. The first roller is located above the second roller. The width of the second roller is greater than that of the first roller, and the diameter of the second roller is greater than that of the first roller. The first roller is a rubber wheel, and the second roller is an iron wheel. The central axes of the first roller and the second roller are parallel to the central axis of the forming roller. During operation, the two material pressing components respectively correspond to the joints between the two sides of the tread cap and the tire shoulder, and the joints between the tire shoulder and the tread cap are subjected to material pressing operations through the cooperation of the first roller and the second roller, reducing the formation of air bubbles and improving the bonding quality.

[0015] Embodiment

[0016] Such as Figure 1-2As shown in the figure, the utility model provides an anti-bubble forming machine for tire production, which includes a frame 1 and a forming roller 2 arranged on the frame 1. The forming roller 2 is matched with a material pressing mechanism. The material pressing mechanism includes two symmetrically arranged material pressing components on the left and right. The material pressing component includes a mounting plate 9, a first telescopic rod 12, a first roller 11 and a second roller 10. The fixed end of the first telescopic rod 12 is connected to the frame 1, and the telescopic end of the first telescopic rod 12 is connected to the mounting plate 9. The first roller 11 and the second roller 10 are respectively arranged at both ends of the mounting plate 9. The first roller 11 is located above the second roller 10. The width of the second roller 10 is greater than the width of the first roller 11, and the diameter of the second roller 10 is greater than the diameter of the first roller 11. The central axes of the first roller and the second roller are parallel to the central axis of the forming roller. The first roller 11 is a rubber wheel, and the second roller 10 is an iron wheel. Such a setting can improve the material pressing effect, reduce friction and improve durability. During operation, the two material pressing components respectively correspond to the joints on both sides of the tire crown and the tire shoulder. Through the cooperation of the first roller 11 and the second roller 10, the joint between the tire shoulder 17 (rubber sheet) and the tire crown 16 (rubber sheet) is subjected to a material pressing operation, reducing the formation of bubbles and improving the bonding quality.

[0017] The two material pressing components are connected to the frame 1 through a moving component. The moving component includes a bidirectional screw 3, a guide rod 6, and a forward and reverse motor 5. The bidirectional screw 3 is parallel to the central axis of the forming roller 2. Both ends of the bidirectional screw 3 are rotatably connected to the frame 1 through bearings. One end of the bidirectional screw 3 penetrates through the frame 1 and is connected to the forward and reverse motor 5. Sliders 4 are in threaded engagement with both the forward thread and the reverse thread of the bidirectional screw 3. Vertical telescopic rods 14 are fixedly connected to the two sliders 4 respectively. The tops of the telescopic rods 14 are respectively hinged to the fixed ends of the telescopic rods 12 of the corresponding material pressing components through hinge shafts 15. The guide rod 6 is parallel to the bidirectional screw 3. Both ends of the guide rod 6 are fixedly connected to the frame 1. Two sliders 7 are slidably sleeved on the guide rod 6. The sliders 7 can rotate along the guide rod 6. The two sliders 7 correspond to the two sliders 4 one by one. Guide blocks 8 are fixed on the two sliders 7. Guide holes are provided on the guide blocks 8. The telescopic ends of the telescopic rods 12 pass through the guide holes and are connected to the mounting plate 9. By the forward and reverse rotation of the forward and reverse motor 5, the two sliders 4 can move towards or away from each other on the bidirectional screw 3, thereby driving the two material pressing components to move towards or away from each other, so that the roller 11 and the roller 10 perform a material pressing operation on the carcass on the forming roller 2 in the horizontal direction, increasing the material pressing range, improving the material pressing effect, and further reducing the generation of bubbles. By the telescoping of the telescopic rod 14, the height of the telescopic rod 12 can be adjusted. In cooperation with the telescoping of the telescopic rod 12, the fitting degree between the roller 11 and the roller 10 and the forming roller can be further adjusted, improving the material pressing effect. In this embodiment, pressure sensors can be provided on the roller 11 and the roller 10. The pressure sensors are electrically connected to the telescopic rod 12 and the telescopic rod 14, further ensuring the reliable contact between the roller 11 and the roller 10 and the rubber sheet on the forming roller, and ensuring the material pressing effect.

[0018] Two auxiliary holes are further provided on the guide block 8. The two auxiliary holes are respectively arranged on the upper and lower sides of the guide hole. Auxiliary rods 13 penetrate through the two auxiliary holes. One ends of the two auxiliary rods 13 are respectively fixedly connected to the upper and lower ends of the corresponding mounting plate 9. The other ends of the two auxiliary rods 13 are respectively fixedly connected with plugs. This setting improves the stability of the roller 11 and the roller 10 on the mounting plate 9 during the moving process, and further improves the material pressing effect.

[0019] The telescopic rod 14 is an electric push rod or a hydraulic rod.

[0020] The telescopic rod 12 is an electric push rod or a hydraulic rod.

[0021] Working principle: During operation, first, both sets of pressure-applying components are located at the center of the tire crown. Subsequently, the lengths of the first telescopic rod and the second telescopic rod are adjusted so that both sets of the first rollers and the second rollers are in reliable contact with the rubber sheet on the forming roller. Then, the forming roller rotates, the forward and reverse motor rotates, and the two sets of pressure-applying components move away from each other. In cooperation with the rotation of the forming roller, an efficient pressure-applying operation is performed on the carcass on the forming roller, and the air bubbles at the bonding position can be extruded. During the movement of the first rollers and the second rollers, the lengths of the first telescopic rod and the second telescopic rod can be flexibly adjusted in a timely manner according to the contact situation with the rubber sheet to ensure the pressure-applying effect of the first rollers 11 and the second rollers 10, reduce the formation of air bubbles, and improve the bonding quality. In this embodiment, when the forming roller does not rotate and the interfaces of the pressure-applying components correspond to the tire crown, the two sets of pressure-applying components move towards or away from each other, and the interfaces of the tire crown can be pressed. When the two sets of pressure-applying components respectively correspond to the bonding positions of the tire crown and the tire shoulder, the forward and reverse motor does not rotate and the forming roller rotates, and the bonding positions of the tire crown and the tire shoulder can be pressed.
