Description

Technical Field

[0001] The utility model relates to the technical field of cord production, in particular to a pneumatic tension regulating device. Background Art

[0002] Cord is short for cord. It is the warp material of woven cord. The materials of cord include cotton yarn, viscose fiber, polyamide fiber, polyvinyl alcohol fiber, glass fiber, aromatic polyamide fiber and steel wire, etc., and their properties are different. They are often selected according to the performance requirements of rubber products and factors such as cost.

[0003] During production, the cord needs to be woven and coated with rubber to increase its strength, and its tension needs to be adjusted before weaving the cord. By adjusting the tension of the cord, it can be ensured that the cord remains stable and uniform during the weaving or production process, which helps to avoid loosening or excessive tension of the cord, thereby ensuring the quality and appearance of the final product. The tension of the cord directly affects the density and texture of the weaving. Proper adjustment of the tension can make the braided fabric tighter and more uniform, thereby improving the overall quality of the product. During the weaving process, if the tension of the wire is not appropriate, it is easy to cause the wire to become knotted or entangled, which will not only affect work efficiency, but may also damage the weaving tools or equipment.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4As shown, a pneumatic tension adjustment device includes a frame 1, which is composed of several plates and can support the structure on its surface. A moving mechanism 3 is installed on one side of the frame 1, and the moving mechanism 3 can drive the cord on its surface to move, so as to facilitate the subsequent adjustment of the tension of the cord. Auxiliary rollers 2 are rotatably connected to both sides of the surface of the frame 1. The auxiliary rollers 2 are used in conjunction with the moving mechanism 3. Under this action, the cord can be simply limited before and after the cord contacts the moving mechanism 3, so as to facilitate the operation of the moving mechanism 3. A connecting frame 4 is fixedly connected to one side of the frame 1, and the connecting frame 4 is L The connecting frame 4 has a U-shaped structure design, an air pump 5 is bolted to one side of the top of the connecting frame 4, and an air pipe 6 is connected to the air outlet of the air pump 5. The air pipe 6 is of U-shaped design, and one end of the air pipe 6 penetrates into the interior of the frame 1 and is fixedly connected to the inner wall of the penetration point. One end of the air pipe 6 is connected to a voltage divider 7, and one side of the voltage divider 7 is fixedly connected to the inner wall of the connecting frame 4. Under the action of the connecting frame 4, the voltage divider 7 can be supported so that it will not easily shift in position during use, so as to avoid the position of the voltage divider 7 shifting and affecting the adjustment of the cord tension. A fixed pipe 8 is connected to the lower part of the surface of the voltage divider 7, and the fixed pipe 8 is fixed to the lower part of the surface of the voltage divider 7. There are several tubes 8, which are evenly distributed on the surface of the voltage divider 7. The bottom of the fixed tube 8 is fixedly connected to a chassis 9, and the inner wall of the chassis 9 is slidably connected to a connecting rod 11. The top of the connecting rod 11 is fixedly connected to a movable plug 10, and the movable plug 10 is made of rubber. The surface of the movable plug 10 is slidably connected to the inner wall of the fixed tube 8. Under this action, the voltage divider 7 and the upper part of the inner cavity of the voltage divider 7 can be in a sealed state, so that when the internal pressure of the voltage divider 7 and the fixed tube 8 is the same, the movable plug 10 can apply pressure downward through the connecting rod 11. The bottom of the connecting rod 11 is fixedly connected to a roller 12. The movable plug 10 and the connecting rod 11 cooperate to move the roller 12 so that the roller 12 can squeeze the cord and keep it in a taut state. Under the action of the air inside the voltage divider 7, the pressure on each roller 12 can be the same, so as to adjust the tension of the cord. A positioning groove 13 is provided on the surface of the roller 12. The inner wall of the positioning groove 13 is arc-shaped. The positioning groove 13 is used in conjunction with the roller 12. The positioning groove 13 can limit the cord so that it will not easily leave the surface of the roller 12, so that the roller 12 can continue to squeeze the cord.

[0022] The moving mechanism 3 includes a stepper motor 31, one side of the stepper motor 31 is bolted to the surface of the frame 1, and belt pulleys 32 are provided at two locations on one side of the frame 1. The other end of the belt pulley 32 passes through the other side of the frame 1 and is rotatably connected to the inner wall of the penetration location. A moving roller 34 is fixedly connected to one side of the belt pulley 32. The output shaft of the stepper motor 31 is fixedly connected to the surface of the belt pulley 32 on one side, and a timing belt 33 is movably connected to the surface of the belt pulley 32. Under this action, the stepper motor 31 can simultaneously drive the two moving rollers 34 to rotate, thereby moving the cord.

[0023] It is worth noting that the technical features such as the stepper motor 31 and the air pump 5 proposed in this technical solution should be regarded as the prior art. The specific structure, working principle and possible control method and spatial arrangement method of these technical features can be selected according to the conventional methods in the field, and this technical solution will not be further elaborated.

[0024] Working principle: First, the cord is wound around the bottom of the auxiliary roller 2 on one side, the top of the moving roller 34 on one side, the inside of the positioning groove 13, the top of the moving roller 34 on the other side and the bottom of the auxiliary roller 2 on the other side in turn, and then the air pump 5 is turned on. Under the action of the air pump 5, the air pipe 6, the voltage divider 7 and the interior of the fixed tube 8 will be inflated, so that the air pressure inside the fixed tube 8 can be stable at this time, and then with the cooperation of the movable plug 10, the roller 12 will be driven by the connecting rod 11 to squeeze the cord so that it can be taut, and then the stepper motor 31 is turned on to drive the moving roller 34 to rotate through the cooperation of the belt pulley 32 and the timing belt 33, so that it drives the cord to move, and when the tension of the cord is different, the pressure of the cord on the roller 12 will be reduced, and the position of the roller 12 will be adjusted under the action of the air inside the fixed tube 8, so that the tension of all cords can be the same, and then the cord with adjusted tension can enter the next process.
