Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a synchronous cutting device for tire materials. Background Art

[0002] In the tire manufacturing process, in order to ensure the specifications and performance requirements of each tire, the length and quality of the molding material need to be precisely controlled. It is very important to control the length and quality of the material to ensure that the performance, durability and safety of each tire meet the standards. When cutting the tire material, the material on the conveyor belt needs to be pushed onto the platform, and the blade is pressed on the platform to cut the material. However, since most tire materials are made of rubber, when the conveyor belt pushes the material onto the platform, the friction between the rubber material and the platform surface is large, which may cause the material to bend or slide, making it difficult to control the length and quality of the material after cutting. In view of this, the utility model proposes a synchronous cutting device for tire materials. Utility Model Content

A conveyor belt is jointly mounted on the active rollers and the driven rollers, and the raw materials are placed on the top of the conveyor belt.

[0006] Optionally, the conveying mechanism also includes a first servo motor and a rotating rod. The first servo motor is installed on one side of a group of side plates away from the active roller. The output end of the first servo motor passes through a group of side plates for its installation and is fixedly connected to the rotating rod.

Sliding sleeves are slidably connected to the sliding rods, and a moving plate is fixedly connected to the two sliding sleeves together. The moving plate is arranged in a "冂" shape.

[0008] Optionally, the traction mechanism further includes clamping plates, a synchronous plate, and a first push rod motor. Multiple clamping plates are slidably connected to the moving plate. The clamping plates are arranged in an L shape. A synchronous plate is fixedly connected to the tops of the multiple clamping plates together.

[0009] Optionally, the synchronization component includes a first one-way bearing, a first belt pulley, a second servo motor, a second one-way bearing, a second belt pulley, and a synchronous belt. One end of the rotating rod away from the first servo motor penetrates through the side plate and is equipped with a first one-way bearing.

The output end of the second servo motor penetrates through the mounting frame and is equipped with a second one-way bearing. The second belt pulley is arranged on the outer ring of the second one-way bearing. A synchronous belt is connected between the first belt pulley and the second belt pulley.

At the same time, with the setting of the first one-way bearing, the first belt pulley rotates synchronously and drives the synchronous belt to move, so that the moving plate moves synchronously, making the movement of the raw material stable, without bending or slipping, ensuring that it is convenient to control the truncation length and quality of the material.

[0014] Further, by setting the second one-way bearing, after the second servo motor is started, the second pulley is driven to rotate synchronously, thereby driving the synchronous belt to move in the opposite direction. At the same time, due to the setting of the first one-way bearing, the rotating rod will not be driven to rotate, so that the position of the raw material remains stationary, but the moving plate is close to the conveying mechanism, which is convenient for continuing to clamp one end of the raw material, thereby realizing a cyclic cutting operation;

[0015] In summary, the utility model pulls the raw materials simultaneously when pushing the raw materials, preventing the raw materials from bending or sliding during the process of moving to the platform, thereby facilitating the control of the length and quality after truncation and ensuring the quality of the finished tire products.

[0031] Example

[0032] like Figure 1 and Figure 2As shown in the figure, a synchronous truncation device for tire materials proposed by the present utility model includes a platform 1 with a hard surface to facilitate truncation. A conveying mechanism 2 is arranged on one side of the platform 1, and the conveying mechanism 2 is used to convey the raw material 3. The conveying mechanism 2 includes side plates 21, a driving roller 22, a driven roller 23, and a conveyor belt 24. Two groups of side plates 21 are respectively arranged on both sides of the platform 1. A driving roller 22 is rotatably connected between the two groups of side plates 21. A plurality of groups of driven rollers 23 are also rotatably connected between the two groups of side plates 21. A conveyor belt 24 is sleeved and installed on the driving roller 22 and the driven roller 23. After the driving roller 22 rotates, it drives the conveyor belt 24 to move, realizing the transportation of the raw material 3. The raw material 3 is placed on the top of the conveyor belt 24. The conveying mechanism 2 further includes a first servo motor 25 and a rotating rod 26. A first servo motor 25 is installed on one side of a group of side plates 21 away from the driving roller 22. The output end of the first servo motor 25 penetrates through a group of side plates 21 for its installation and is fixedly connected to a rotating rod 26. The rotating rod 26 is fixedly connected to the driving roller 22. After the first servo motor 25 is started, it drives the rotating rod 26 to rotate and simultaneously drives the driving roller 22 to rotate.

[0033] Specifically, please refer to Figure 3 , the above-mentioned truncation device includes a traction mechanism 4 installed on the top of the platform 1, and the traction mechanism 4 is used to clamp one end of the raw material 3. The traction mechanism 4 includes fixing blocks 41, sliding rods 42, sliding sleeves 43, and a moving plate 44. Two groups of fixing blocks 41 are fixedly connected to the top of the platform 1. One group of fixing blocks 41 is respectively fixedly connected to the tops of the two groups of side plates 21. Sliding rods 42 are fixedly connected between the two groups of fixing blocks 41 on the top of the platform 1 and the fixing blocks 41 on the tops of the two groups of side plates 21. The positions of the fixing blocks 41 and the sliding rods 42 are fixed. A sliding sleeve 43 is slidably connected to the sliding rod 42. A moving plate 44 is fixedly connected to the two groups of sliding sleeves 43. The moving plate 44 is arranged in a "冂" shape. The moving plate 44 moves smoothly under the limiting action of the sliding sleeve 43 and the sliding rod 42. The traction mechanism 4 further includes clamping plates 45, a synchronous plate 46, and a first push rod motor 47. Two groups of clamping plates 45 are slidably connected to the moving plate 44. The clamping plates 45 are arranged in an L shape. A synchronous plate 46 is fixedly connected to the tops of the two groups of clamping plates 45. The synchronous plate 46 moves synchronously with the two groups of clamping plates 45. Thus, when the clamping plates 45 move upward, one end of the raw material 3 is clamped between the moving plate 44 and the clamping plates 45. A first push rod motor 47 is also installed on the top of the moving plate 44. The output end of the first push rod motor 47 is fixedly connected to the synchronous plate 46. The first push rod motor 47 is used to drive the synchronous plate 46 to move after being started.

[0034] Furthermore, the above-mentioned cutting device also includes a synchronization component 5 installed on one side of the platform 1 and the conveying mechanism 2. The synchronization component 5 is used to drive the traction mechanism 4 to move synchronously when the conveying mechanism 2 drives the raw material 3 to move, so that when the conveying mechanism 2 pushes the raw material 3, the traction mechanism 4 synchronously pulls the raw material 3 to move, preventing the raw material 3 from bending or sliding, and facilitating the control of the cut length and quality of the raw material 3. The synchronization component 5 includes a first one-way bearing 51, a first pulley 52, a second servo motor 53, a second one-way bearing 54, a second pulley 55, and a synchronous belt 56. The end of the rotating rod 26 away from the first servo motor 25 passes through the side plate 21 and is installed with the first one-way bearing 51. The outer ring of the first one-way bearing 51 is installed with the first pulley 52. ​​The first one-way bearing 51 allows the first pulley 52 to rotate synchronously when the conveying mechanism 2 drives the raw material 3 to move toward the side of the platform 1. When the conveying mechanism 2 drives the raw material 3 away from the platform 1, the first pulley 52 does not rotate accordingly. A second servo motor 53 mounted on a mounting frame is also provided on the side of the platform 1 away from the conveying mechanism 2. The output end of the second servo motor 53 passes through the mounting frame and is installed with a second one-way bearing 54. A second pulley 55 is provided on the outer ring of the second one-way bearing 54. A synchronous belt 56 is connected between the first pulley 52 and the second pulley 55. When the conveying mechanism 2 drives the first pulley 52 to rotate, the second pulley 55 is driven to rotate through the synchronous belt 56, and the second pulley 55 rotates with the output end of the second servo motor 53 as the axis. After the second servo motor 53 is started, it drives the second pulley 55 to rotate synchronously, and drives the first pulley 52 to rotate with the synchronous belt 56. However, the first pulley 52 does not drive the rotating rod 26 to rotate under the action of the first one-way bearing 51, so as to facilitate the reset of the moving plate 44. The synchronous assembly 5 also includes a connecting plate 57 fixedly connected to the synchronous belt 56. One side of the moving plate 44 is fixedly connected to the connecting plate 57. When the synchronous belt 56 moves, it drives the moving plate 44 to move synchronously through the connecting plate 57.

[0035] Finally, the above-mentioned cutting device also includes a cutting mechanism 6 for cutting the raw material 3, and the cutting mechanism 6 is installed on the platform 1. The cutting mechanism 6 includes a mounting frame 61, a second push rod motor 62, a pressure plate 63, and a blade 64. The mounting frame 61 is installed on the platform 1. The second push rod motor 62 is installed on the top of the mounting frame 61. The output end of the second push rod motor 62 passes through the mounting frame 61 and is fixedly connected to the pressure plate 63. The blade 64 is installed at the bottom of the pressure plate 63. After the second push rod motor 62 is started, it extends and drives the blade 64 to press against the raw material 3 to achieve cutting of the raw material 3. Two sets of limit rods are also arranged on the top of the pressure plate 63. The limit rods are also slidably sleeved with a limit sleeve installed on the mounting frame 61, so that the movement of the blade 64 is stable and the accuracy of cutting is ensured.

[0036] In this embodiment, first, the first servo motor 25 is started to drive the rotating rod 26 to rotate, so that the active roller 22 rotates and drives the conveyor belt 24 to move to transport the raw material 3, so that one end of the raw material 3 protrudes from the top of the conveyor belt 24. The second servo motor 53 is started, and the second servo motor 53 drives the second pulley 55 to rotate through the second one-way bearing 54, so that the second pulley 55 drives the first pulley 52 to rotate through the synchronous belt 56. Under the action of the first one-way bearing 51, the first pulley 52 will not drive the rotating rod 26 to rotate when rotating. At this time, the synchronous belt 56 drives the moving plate 44 to move through the connecting plate 57 when moving. The moving plate 44 moves smoothly under the limiting action of the sliding rod 42 and the sliding sleeve 43, so that the moving plate 44 is close to the raw material 3 until one end of the raw material 3 is located between the moving plate 44 and the clamping plate 45. At this time, the first push rod motor 47 is started to extend, and the first push rod motor 47 drives the synchronous plate 46 to move upward, so that the two groups of clamping plates 45 move upward and clamp one end of the raw material 3. At this time, the first servo motor 25 is started, and the first servo motor 25 drives the rotating rod 26 and the active roller 22 to rotate, so that the conveyor belt 24 moves to push the raw material 3 to the top of the platform 1. At the same time, the rotating rod 26 drives the first pulley 52 to rotate synchronously through the setting of the first one-way bearing 51 when rotating, so that the first pulley 52 drives the synchronous belt 56 to move, and at this time the synchronous belt 56 drives the connecting plate 57 away from the conveying mechanism 2. At this time, the moving plate 44 moves in the direction away from the conveying mechanism 2, and at the same time pulls one end of the raw material 3 to move synchronously, so that the movement of the raw material 3 is stable, and there will be no bending and sliding. Finally, when the raw material 3 moves to the appropriate position, the second push rod motor 62 starts to drive the blade 64 to press down to cut the raw material 3.

[0037] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
