[0004] The aforementioned patent describes a knitted fabric flattening device. In the prior art, flattening devices are equipped with tension rollers to provide tension to the fabric and ensure the fit between the fabric and the heating roller. However, the tension rollers are usually fixed. When placing the fabric, it is necessary to pass the fabric back and forth between the interlaced tension rollers, which is very cumbersome and inconvenient and does not improve processing efficiency. Therefore, we propose a knitted fabric flattening device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a knitted fabric flattening device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a knitted fabric flattening device, comprising a base, a heating roller, and a quick tensioning device. The heating roller is mounted on the center of the inner side of the base. Quick tensioning devices are provided on the left and right sides of the inner side of the base. Each quick tensioning device includes a stepper motor, tensioning rollers, a turntable, a support roller, a guide block, a guide groove, and a locking mechanism. Stepper motors are symmetrically mounted on the left and right sides of the front of the base. Tensioning rollers are mounted on the left and right sides of the inner side of the base. Turntables are symmetrically mounted at the front and rear ends of the tensioning rollers. The turntables are rotatably connected to the inner wall of the base using bearings. The output shaft of the stepper motor is connected to the rotation point of the turntable. Support rollers are rotatably mounted on the left and right edges of the inner side of the base.

[0007] Preferably, the turntable has an eccentric wheel structure.

[0008] Preferably, the inner roller spacing of the tensioning rollers is not less than 10cm.

[0009] Preferably, a guide block is integrally provided on the edge of the turntable surface, and guide grooves are symmetrically provided on the front and rear walls of the inner side of the base, with the guide block and the guide groove being embedded and slidably inserted into each other.

[0010] Preferably, the turning angle range of the turntable does not exceed 135°.

[0011] Preferably, the locking mechanism is disposed on the surface of the turntable. The locking mechanism includes a cylinder actuator, a first locking hole, and a second locking hole. The cylinder actuators are symmetrically installed on the left and right sides of the front of the base. The cylinder actuators are adjacent to the installation position of the stepper motor. The telescopic end of the cylinder actuator extends horizontally into the inner side of the base. The first locking hole and the second locking hole are distributed on the surface of the turntable. When the turntable is in the upward flipped state, the first locking hole is inserted and connected to the telescopic end of the cylinder actuator. When the turntable is in the downward flipped state, the second locking hole is inserted and connected to the telescopic end of the cylinder actuator.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention features a quick-tensioning device installed on the left and right sides of the inner side of the machine base. When placing the fabric, the turntable is first rotated to the upward position by a stepper motor. At this time, the tensioning rollers are directly opposite the two sides of the heating drum, so that the fabric can be inserted into the inner side of the tensioning rollers. Then, the fabric is wrapped around the surface of the heating drum, and finally, the fabric is taken out from the inner side of the other tensioning roller, thus completing the fabric placement. The process is quick and does not require back-and-forth fabric threading, greatly improving the fabric placement speed.

[0013] This invention features a locking mechanism on the surface of the turntable. When the turntable is in the upward position, the first locking hole is connected to the telescopic end of the cylinder actuator. When the turntable is in the downward position, the second locking hole is connected to the telescopic end of the cylinder actuator, thereby locking the turntable at the working angle. This prevents the turntable from shaking during use and improves the stability of the equipment operation. Attached Figure Description

[0016] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0017] Please see Figure 1 This utility model provides a knitted fabric flattening device, including a machine base 1, a heating roller 2 and a quick tensioning device 3. The heating roller 2 is mounted on the middle of the inner side of the machine base 1, and the quick tensioning device 3 is provided on the left and right sides of the inner side of the machine base 1.

[0018] Please see Figure 2-3 This utility model provides a knitted fabric flattening device. The quick tensioning device 3 includes a stepper motor 31, tensioning rollers 32, turntables 33, support rollers 34, guide blocks 35, guide grooves 36, and a locking mechanism 37. The stepper motors 31 are symmetrically installed on the left and right sides of the front of the machine base 1. The tensioning rollers 32 are mounted on the left and right sides of the inner side of the machine base 1. The turntables 33 are symmetrically installed at the front and rear ends of the tensioning rollers 32. The turntables 33 are rotatably connected to the inner wall of the machine base 1 by bearings. The output shaft of the stepper motor 31 is installed and connected to the rotation point of the turntable 33. The support rollers 34 are rotatably installed on the left and right edges of the inner side of the machine base 1.

[0019] Among them, the turntable 33 is an eccentric wheel structure, which can twist the angle of the tensioning roller 32 to a greater extent to ensure tensioning performance.

[0020] The inner roller spacing of the tensioning roller 32 is not less than 10cm, which facilitates the fabric to be inserted through the inner side of the tensioning roller 32 and realizes the rapid placement of the fabric.

[0021] Specifically, by setting quick tensioning devices 3 on the left and right sides inside the machine base 1, when placing the fabric, the turntable 33 is first rotated to the upward state by the stepper motor 31. At this time, the tensioning rollers 32 are directly opposite the two sides of the heating roller 2 so that the fabric can be inserted into the inside of the tensioning rollers 32. Then the fabric is wrapped around the surface of the heating roller 2. Finally, the fabric is taken out from the inside of the tensioning rollers 32 on the other side. The support rollers 34 can provide basic support for the fabric on both sides of the machine base 1 to prevent the fabric from shifting up and down, thereby completing the placement of the fabric. During the tensioning action, the stepper motor 31 controls the turntable 33 to rotate to the downward state. During this process, the turntable 33 drives the tensioning roller 32 to twist, increasing the degree of curvature between the tensioning roller 32 and the heating roller 2, thereby tensioning the fabric and ensuring a tight fit between the fabric and the heating roller 2, thus guaranteeing a smoothing effect.

[0022] Please see Figure 4-5 This utility model provides a knitted fabric flattening device. A guide block 35 is integrally provided on the edge of the surface of the turntable 33. A guide groove 36 is symmetrically provided on the front and rear walls of the inner side of the machine base 1. The guide block 35 and the guide groove 36 are embedded and slid inward. The maximum turning angle of the turntable 33 is limited by the structural cooperation between the guide block 35 and the guide groove 36, so as to prevent the turntable 33 from exceeding the safe angle and causing the fabric to break.

[0023] To further explain, the turning angle of turntable 33 does not exceed 135° to avoid excessive twisting of tension roller 32, which could cause the fabric to break.

[0024] Please see Figure 6 This utility model provides a knitted fabric flattening device. A locking mechanism 37 is disposed on the surface of a turntable 33. The locking mechanism 37 includes a cylinder actuator 371, a first locking hole 372, and a second locking hole 373. The cylinder actuator 371 is symmetrically installed on the left and right sides of the front of the machine base 1. The cylinder actuator 371 is adjacent to the stepper motor 31. The telescopic end of the cylinder actuator 371 extends horizontally into the inner side of the machine base 1. The first locking hole 372 and the second locking hole 373 are distributed on the surface of the turntable 33. When the turntable 33 is in the upward flipped state, the first locking hole 372 is inserted into the telescopic end of the cylinder actuator 371. When the turntable 33 is in the downward flipped state, the second locking hole 373 is inserted into the telescopic end of the cylinder actuator 371, thereby locking the turntable 33 at the working angle. It is not easy to shake during use, thus improving the stability of the equipment operation.
