Description

Technical Field

[0001] The utility model relates to the technical field of tension adjustment, and particularly relates to a fabric winding device for automatically adjusting tension. Background Technique

[0002] A fabric is a flat and soft piece formed by crossing, winding, and connecting fine and long objects. Among them, polyester filament belongs to a kind of fabric. Polyester filament is made of polyester into filaments. Polyester is an important variety in synthetic fibers. When polyester filaments are wound, in order to ensure the winding quality, the tension is usually adjusted during winding.

[0003] After retrieval, the Chinese patent "A Polyester Filament Winding Tension Adjusting Device" with the authorization announcement number "CN214934934U" drives the rotation of the winding wheel by the rotation of the motor to drive the rotation of the rotating shaft, so as to wind the polyester filament on the hub of the winding wheel. When the tension of the polyester filament changes, the elastic deformation of the spring inside the sleeve drives the telescopic rod and the fixed pulley to move up and down, so that the polyester filament located inside the sleeve maintains a certain tension, so that the polyester filament can be wound on the winding wheel more smoothly.

[0004] Although the above application can adjust the tension by using a spring, when the tension changes, the spring continuously stretches and contracts, and the elastic force of the spring will decrease after long-term use, thus affecting its tension adjustment effect.

[0005] Therefore, a fabric winding device for automatically adjusting tension is proposed to solve the above problems. Content of the Utility Model

The opposite ends of the two round rods penetrate to the inner side of the mounting frame and are fixedly connected to a second tension roller. The other ends of the two connecting pipes are respectively communicated with the two second cylinders. Adjusting the tension by the flow of gas is beneficial to ensuring the stability of the tension adjustment and improving the service life of the device.

[0009] Preferably, a trigger rod is fixedly connected to the lower end of the surface of one of the first piston rods.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] During specific implementation: As Figures 1-4 shown, an automatic tension-adjusting fabric winding device includes: a base 1, a fixed frame 2 fixedly connected to one side of the top end of the base 1, a winding roller 3 rotatably connected to the upper end of the inner wall of the fixed frame 2, a motor 4 fixedly connected to one side of the fixed frame 2, an output shaft of the motor 4 passing through the fixed frame 2 and fixedly connected to one end of the winding roller 3, and an adjusting mechanism 5 arranged at the top end of the base 1; wherein, the adjusting mechanism 5 includes two mounting frames 51 fixedly connected to the top end of the base 1, a first cylinder 52 fixedly connected to the top end of the mounting frame 51, the bottom end of the first cylinder 52 passing through the mounting frame 51, a first piston rod 53 slidably connected to the inner wall of the first cylinder 52, the bottom end of the first piston rod 53 passing through the first cylinder 52 and fixedly connected to a connecting frame 54, a first tensioning roller 55 rotatably connected to the inner wall of the connecting frame 54, and a connecting pipe 512 communicating with the top end of the first cylinder 52.

[0024] As Figure 2 and Figure 4 shown, the adjusting mechanism 5 further includes a mounting frame 56 fixedly connected to the top end of the base 1, two second cylinders 57 fixedly connected to both sides of the mounting frame 56, a second piston rod 58 slidably connected to the inner wall of the second cylinder 57, the top end of the second piston rod 58 passing through the second cylinder 57 and fixedly connected to a ring 59, a round rod 510 rotatably connected to the inner wall of the ring 59, opposite ends of the two round rods 510 passing through to the inner side of the mounting frame 56 and fixedly connected to a second tensioning roller 511, and the other ends of the two connecting pipes 512 respectively communicating with the two second cylinders 57.

[0025] The second tensioning roller 511 is arranged at the center between the two first tensioning rollers 55, gases are filled in both the inside of the first cylinder 52 and the inside of the second cylinder 57, and the first piston rod 53 and the second piston rod 58 both have moving distances up and down.

[0026] One end of the polyester filament is passed through successively under one of the first tensioning rollers 55, above the second tensioning roller 511, and under the other first tensioning roller 55 and connected to the winding roller 3. The motor 4 is started through a controller to drive the winding roller 3 to rotate for winding operation. When the tension is stable during the winding process of the polyester filament, the gases in the two first cylinders 52 and the two second cylinders 57 are in a constant pressure state. When the tension changes during the winding process of the polyester filament, it will continuously drive the two first tensioning rollers 55 and the second tensioning roller 511 to move up and down, enabling the gases in the two first cylinders 52 and the corresponding gases in the second cylinders 57 to flow and exchange with each other, so that the surfaces of the two first tensioning rollers 55 and the surface of the second tensioning roller 511 are always in contact with the surface of the polyester filament, thereby adjusting the tension.

[0027] During the up-and-down movement of the second tensioning roller 511, the two second piston rods 58 will be driven to move up and down synchronously. At this time, the gas entering and discharging from the second cylinder 57 is the same, so that the two first tensioning rollers 55 move up and down by the same distance, so that the two first tensioning rollers 55 always apply the same force to the polyester filament.

[0028] As Figure 3 shown, a trigger rod 513 is fixedly connected to the lower end surface of one of the first piston rods 53, and a switch 514 is fixedly connected to the upper end of one side of the mounting bracket 51. The switch 514 is electrically connected to the motor 4, and the other end of the trigger rod 513 is located below the switch 514.

[0029] The switch 514 is a trigger switch 514, and the connection method between the switch 514 and the motor 4 is a relatively mature technical means in the prior art. The other end of the trigger rod 513 has a certain distance from the switch 514 in the initial state. During the winding process of the polyester filament, when one of the first piston rods 53 drives the trigger rod 513 to move upward so that the other end of the trigger rod 513 contacts the switch 514, the winding tension of the polyester filament reaches the maximum value, and the polyester filament is over-pulled. When the trigger rod 513 touches the switch 514, the motor 4 is turned off. At this time, the staff can adjust the polyester filament.

[0030] As Figure 4 shown, a spring 515 is fixedly connected to the bottom end of the second piston rod 58, and the other end of the spring 515 is fixedly connected to the inner bottom wall of the second cylinder 57.

[0031] When the gas pushes the second piston rod 58 to move upward, the spring 515 is stretched. When the pressure on the second piston rod 58 gradually decreases, the spring 515 drives the second piston rod 58 to reset. After the winding of the polyester filament is completed, under the action of the spring 515, the two first cylinders 52 and the two second cylinders 57 can be restored to the initial state.

[0032] As Figure 4 shown, through grooves are formed on both sides of the inner wall of the mounting frame 56, and equally spaced rollers 516 are rotatably connected to the inner walls of the through grooves. The surface of the round rod 510 is in contact with the surface of the roller 516. When the round rod 510 moves up and down, it will drive the roller 516 to rotate synchronously.

[0033] As Figure 3 shown, sliding blocks 517 are slidably connected to both sides of the inner wall of the mounting bracket 51, and both sides of the mounting bracket 51 are fixedly connected to the opposite sides of the two sliding blocks 517. Through grooves matching the sliding blocks 517 are formed on both sides of the inner wall of the mounting bracket 51.

[0034] When the utility model is in use, one end of the polyester filament passes under one of the first tension rollers 55, above the second tension roller 511, and under the other first tension roller 55 in sequence and is connected to the winding roller 3. The motor 4 is started through the controller to drive the winding roller 3 to rotate for winding operation. When the tension is stable during the winding process of the polyester filament, the gas in the two first cylinders 52 and the two second cylinders 57 is in a constant pressure state. When the tension changes during the winding process of the polyester filament, it will continuously drive the two first tension rollers 55 and the second tension roller 511 to move up and down, so that the gas in the two first cylinders 52 and the gas in the corresponding second cylinders 57 flow and exchange with each other, so that the surfaces of the two first tension rollers 55 and the surface of the second tension roller 511 are always in contact with the surface of the polyester filament, thereby adjusting the tension. During the winding process of the polyester filament, at the same time, when one of the first piston rods 53 drives the trigger rod 513 to move upward so that the other end of the trigger rod 513 contacts the switch 514 during the winding process, the winding tension of the polyester filament reaches the maximum value, and the polyester filament is over-pulled. When the trigger rod 513 touches the switch 514, the motor 4 is turned off. At this time, the staff can adjust the polyester filament.

[0035] It should be noted that in the above description, the switch 514, the motor 4, etc. are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the motor 4 can be an internal power supply or a mains power supply. The specific power supply method is selected according to the situation and will not be elaborated here.

[0036] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
