Description

Technical Field

[0001] This invention relates to the field of tire manufacturing technology, and in particular to a high-efficiency forming machine for tire manufacturing. Background Technology

[0002] During the tire manufacturing process, different parts of the tire require rubber strips with different formulations. Various additives and even polyester fabrics need to be added to the rubber. The existing tire manufacturing process usually involves first producing rubber strips for different parts in the semi-finished product workshop using an extrusion device, then taking the rubber strips into rolls using a winding device, and then transporting the rolls to the finished product workshop. After the rolls are separated, the different rubber strips are manually attached to the rollers to form tire blanks.

[0003] Existing tire forming machines have a low level of automation, requiring manual assistance at each stage of production. For example... Figure 1 As shown, in the existing manufacturing method, when a hoop is required, the steel wire ring is manually installed on the base layer 14; when the material layer 15 needs to be installed on the base layer 14, the material layer 15 is manually covered on the base layer 14; when the material layer 15 needs to be leveled and vented after installation, the leveling wheel 23 is manually moved on the tire surface; and when the manufacturing is completed and disassembled, the finished product is still manually removed from the air shaft 1. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background art by proposing a high-efficiency molding machine for tire production.

[0005] The technical solution of the present invention: a high-efficiency molding machine for tire production, comprising a molding machine body, the molding machine body including an air expansion shaft, a flattening and venting mechanism, a stabilizing mechanism, a moving track device, a hoop mechanism, a conveying mechanism, and a receiving platform. The air expansion shaft, the flattening and venting mechanism, the stabilizing mechanism, and the moving track device are all mounted on the mounting frame. A base layer is pre-fitted onto the air expansion shaft. Flanging manipulators for flanging the base layer are mounted on both sides of the air expansion shaft. The hoop mechanism is disposed on the moving track device and includes two hoop assemblies for installing steel wire rings on the base layer. The conveying mechanism is mounted on the auxiliary mounting frame and is located on one side of the air expansion shaft. A material layer is conveyed on the conveying mechanism. The flattening and venting mechanism is located above the air expansion shaft and includes flattening wheels for flattening and venting the base layer and the material layer.

[0006] Preferably, the air expansion shaft includes a drive shaft, and mounting seats are fitted on both sides of the drive shaft. A first cylinder is installed between the mounting seats and the air expansion shaft. The flanging robot is mounted on the mounting seats, and the two flanging robots are located on both sides of the base layer.

[0007] Preferably, the stabilizing mechanism includes a base fixedly mounted on the mounting bracket, a second cylinder mounted on the base, a stabilizing seat mounted on the pushing end of the second cylinder, an electric push rod mounted inside the stabilizing seat, and a bearing sleeve mounted on the pushing end of the electric push rod.

[0008] Preferably, there are two pushing and venting mechanisms, which are located on both sides of the air expansion shaft. Each pushing and venting mechanism includes an electric guide rail device fixedly mounted on the mounting frame. Two support frames are mounted on the electric guide rail device. A first electric cylinder is mounted on the support frame. A running platform is mounted on the pushing end of the first electric cylinder. The pushing wheel is rotatably mounted between the two running platforms.

[0009] Preferably, the conveying mechanism includes a transmission device mounted on the auxiliary mounting frame. The transmission device includes a conveying table, the material layer is located on the conveying table, a frame is mounted on the transmission device, a second electric cylinder is mounted on the frame, a conveying cover plate is mounted on the pushing end of the second electric cylinder, the material layer is located between the conveying table and the conveying cover plate, and a squeezing roller is rotatably mounted on one end of the conveying cover plate near the air expansion shaft.

[0010] Preferably, the hoop assembly includes a frame mounted on the moving track device, the frame having two hoop mounting arms, and the wire ring can be installed inside the hoop mounting arms.

[0011] Preferably, a bidirectional cylinder is installed inside the seat frame, and the pushing ends on both sides of the bidirectional cylinder are fixedly connected by the hoop mounting arms.

[0012] Compared with existing technologies, the beneficial effects of this invention are:

[0013] 1. This invention forms a complete tire manufacturing process by setting up an air expansion shaft, a flattening and venting mechanism, a stabilizing mechanism, a moving track device, a clamping mechanism, and a conveying mechanism. The clamping mechanism can clamp the base layer, eliminating the need for manual installation of steel wire rings. By setting up flanging robots on both sides of the air expansion shaft, the flanging operation on both sides of the base layer can be performed by the flanging robots alone, eliminating the need for manual flanging. Then, the conveying mechanism can install the material layer on the base layer. Then, the flattening and venting mechanism can flatten and vent the base layer and the material layer. Finally, the clamping mechanism can remove the finished tire. Thus, the entire process has a high level of automation and greatly improves the efficiency of tire production.

[0024] Example 2

[0025] See attached document Figure 3 and 6 Based on Embodiment 1, the stabilizing mechanism 3 includes a base 31 fixedly mounted on the mounting bracket 8. A second cylinder 32 is mounted on the base 31. A stabilizing seat 33 is mounted on the pushing end of the second cylinder 32. An electric push rod 35 is mounted inside the stabilizing seat 33. A bearing sleeve 34 is mounted on the pushing end of the electric push rod 35. When the air shaft 1 is operating, the second cylinder 32 is activated to push the stabilizing seat 33 to rise, so that the bearing sleeve 34 and the drive shaft 11 are level. Then, the electric push rod 35 is activated to move the bearing sleeve 34, so that the unloading end of the drive shaft 11, and the left end of the drive shaft 11, as shown in the attached stabilizing mechanism 3, will enter the bearing sleeve 34, thereby making the air shaft 1 more stable when rotating.

[0026] Example 3

[0027] See attached document Figure 3Based on the above embodiment one or two, the leveling and venting mechanism 2 is located above the air expansion shaft 1. The leveling and venting mechanism 2 includes a leveling wheel 23 for leveling and venting the base layer 14 and the material layer 15. There are two leveling and venting mechanisms 2, which are located on both sides of the air expansion shaft 1. The leveling and venting mechanism 2 includes an electric guide rail device 21 fixedly installed on the mounting frame 8. Two support frames 25 are installed on the electric guide rail device 21. A first electric cylinder 24 is installed on the support frame 25. A running platform 22 is installed on the pushing end of the first electric cylinder 24. The leveling wheel 23 is rotatably installed between the two running platforms 22.

[0028] The workflow of the high-efficiency molding machine for tire production is as follows:

[0029] 1. Before operation, the base layer 14 to be processed is placed on the air expansion shaft 1. Then, the second cylinder 32 is started to raise the stabilizing seat 33. The electric push rod 35 is started to move the bearing sleeve 34 outward, so that the outer end of the drive shaft 11 enters the bearing sleeve 34. Then, the air expansion shaft 1 is started to expand the base layer 14 for hooping operation.

[0030] 2. Before hooping, the steel wire ring 54 is inserted into the hoop mounting arm 55. After the base layer 14 is expanded, the hooping mechanism 5 is activated. The hooping mechanism 5 drives the moving track device 4 to move towards the air expansion shaft 1. During the movement, the bidirectional cylinder 53 is activated. The bidirectional cylinder 53 separates the two hoop mounting arms 55 away. As the moving track device 4 moves continuously, the air expansion shaft 1 will pass through the two hoop mounting arms 55. After the movement is completed, the two hoop mounting arms 55 are located at both ends of the base layer 14. Then, the bidirectional cylinder 53 is activated again to close the two hoop mounting arms 55, so that the steel wire ring 54 is hooped on the base layer 14 to complete the hooping operation.

[0031] 3. After the hooping operation is completed, the flanging operation is carried out. The first cylinder 13 is started to move the mounting seat 12 closer to the base layer 14, so that the flanging robot 10 pushes the side of the base layer 14 to perform the flanging operation. After flanging, the wire ring 54 is wrapped.

[0032] 4. After the flanging is completed, the material layer 15 is installed. The transmission device 61 is started to drive the conveyor table 66 to move. The second electric cylinder 63 is started to push the conveyor cover plate 64 to move. The material layer 15 will move between the conveyor table 66 and the conveyor cover plate 64. The material layer 15 will be pressed by the rotation of the extrusion roller 62 so that one end of the material layer 15 will cover the base layer 14. At this time, the air shaft 1 is in the rotating state, so that the entire material layer 15 will cover the base layer 14.

[0033] 5. After the material layer 15 is installed on the base layer 14, the base layer 14 and the material layer 15 are then leveled and vented. The electric guide rail device 21 and the first electric cylinder 24 are started. The pushing end of the first electric cylinder 24 causes the running table 22 to rise, and the leveling wheel 23 contacts the material layer 15 to level and vent the base layer 14 and the material layer 15. The electric guide rail device 21 will drive the support frame 25 to move back and forth, so that the work can be carried out around the tire.

[0034] 6. Finally, restart the moving track device 4 to move the hoop mechanism 5. During the movement, activate the bidirectional cylinder 53. The bidirectional cylinder 53 separates the two hoop mounting arms 55. As the moving track device 4 continues to move, the air shaft 1 will pass through the two hoop mounting arms 55. After the movement is completed, the two hoop mounting arms 55 are located at the two ends of the base layer 14. Then, restart the bidirectional cylinder 53 to close the two hoop mounting arms 55. At this time, the two hoop mounting arms 55 will clamp the tire. Then, the hoop mechanism 5 returns to its position. Remove the tire, move it onto the receiving platform 7, and restart the bidirectional cylinder 53 to separate the two hoop mounting arms 55. The tire then falls into the receiving platform 7.
