Description

Technical Field

[0001] This utility model relates to the field of garment processing and production equipment, and in particular to a tension adjustment device for a fabric opening machine. Background Technology

[0002] A fabric spreading machine is a type of mechanical equipment specifically designed for the textile industry. Its core function is to precisely spread and flatten cylindrical knitted fabric into a single-layer spread structure through a physical spreading device, eliminating internal twist of the fabric, preventing wrinkles and deformation, and ultimately ensuring a flat output. It is suitable for the production processes of various materials such as cotton yarn, blended fabrics, and polyester.

[0003] CN207861537U discloses a fabric opening machine, including a frame. The frame is equipped with a twist-reducing device, a fabric conveying device, and a fabric output device. The fabric conveying device includes a first tension roller, a second tension roller, and a pressure roller. The first tension roller and the second tension roller are rotatably connected within the frame. The pressure roller is located between the first tension roller and the second tension roller. Adjustment components are provided at both ends of the frame. The adjustment components include a first transmission rod, a second transmission rod, and a drive component. One end of the first transmission rod is hinged to the pressure roller, and the other end is hinged to the frame. One end of the second transmission rod is slidably connected to the pressure roller, and the other end is slidably connected to the frame. The first transmission rod and the second transmission rod are rotatably connected. The drive component is located on the frame.

[0004] This product uses a detwisting device to flatten the fabric, thereby achieving the fabric width. At the same time, by adjusting the height of the pressure roller, the pressure roller presses the fabric to achieve the purpose of fabric tension, thereby reducing the possibility of fabric slippage during transmission. However, the detwisting device strikes the fabric, which will create a tension that is sometimes tight and sometimes loose, causing instability in the fabric width.

[0005] Therefore, those skilled in the art have provided a tension adjustment device for a fabric opening machine to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a tension adjustment device for a fabric opening machine.

The support roller is rotatably connected to the support base.

[0010] The above technical solution, by setting up an impact structure, can control the forward and backward movement of the impact plate to impact the fabric, thereby achieving a vibration effect on the fabric. This can flatten the fabric while knocking off debris on the fabric surface, improving the flatness and cleanliness of the fabric.

[0023] Furthermore, a PLC controller is fixedly connected to one side of the support base, and tension sensors are fixedly connected inside the first sticking roller, the second sticking roller, and the adjusting roller.

[0024] By using the above technical solution, a PLC controller and tension sensor are set up to monitor the fabric tension in real time. The fabric feeding speed or the moving speed of the impact plate is dynamically adjusted by the variable frequency motor to counteract the instantaneous tension fluctuations caused by the impact and improve the stability of the opening width.

[0025] This utility model has the following beneficial effects:

[0027] 2. The tension adjustment device for a fabric opening machine proposed in this utility model, through the setting of an adjustment structure, uses a first adjustment motor to control the up and down movement of the first adhesive roller, which works in conjunction with the second adhesive roller to adhere lint and other impurities on the fabric surface. This adjusts the tension of the fabric while improving its cleanliness and flatness. The second adjustment motor and the moving block control the up and down movement of the adjustment roller, thereby squeezing the fabric and working with the left and right rotating rollers to flatten the fabric, thus achieving tension adjustment and improving the flatness of the fabric. Using a PLC controller and a tension sensor, the fabric tension is monitored in real time. The feed speed of the left and right rotating rollers or the movement speed of the striking plate are dynamically adjusted by a variable frequency motor to counteract the instantaneous tension fluctuations caused by the striking, thereby improving the stability of the opening.
