Technical Field

[0001] This utility model relates to the field of fabric cutting technology, specifically a seat fabric cutting and feeding device. Background Technology

[0002] Seat fabrics refer to the external materials used to cover seats in automobiles, furniture, office chairs, etc. These fabrics typically need to be wear-resistant, easy to clean, comfortable, and durable. There are various choices for seat fabrics, such as leather, cloth, and artificial leather. Leather is widely used in luxury seats, offering a high-end feel and softness; cloth is lightweight and breathable, generally used for home and commercial seating; artificial leather is environmentally friendly and easy to maintain. Different types of seat fabrics need to be selected according to specific usage scenarios and needs to ensure a balance between comfort and functionality. A seat fabric cutting and feeding device is a device used to position and transport the fabric to the working area of ​​the cutting machine.

[0003] Before cutting, using a material roller can help roll up and store the fabric that needs to be cut. This can effectively protect the fabric from dust, pollution and sunlight, and also help with sorting and save space. During the process of rolling up the fabric, the material roller may fix and deepen the wrinkles, making them more difficult to handle when unfolding. After the wrinkled fabric is fed into the cutting equipment, it will affect the cutting quality of the fabric. Utility Model Content

[0004] The purpose of this utility model is to provide a seat fabric cutting and feeding device, which has the advantage of straightening the wrinkled fabric and pressing and fixing the fabric on the material roller during the process of the material roller winding the fabric to be cut, so as to avoid the wrinkled fabric affecting the cutting quality. It solves the problem that the feeding device cannot process the wrinkled fabric during the fabric storage process, which causes the wrinkled fabric to enter the cutting equipment and affect the cutting quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a seat fabric cutting and feeding device, comprising a feeding frame, with fixed rods movably installed on both sides of the feeding frame, and a material roller installed at one end of each of the two fixed rods. Two springs are symmetrically installed at the bottom of the feeding frame, and fixed frames are installed on the top of the two springs. A bearing roller is rotatably installed inside the fixed frames. Support frames are welded to both the front and rear sides of the feeding frame, and each of the two support frames has a screw hole. A screw rod is threaded into the inner wall of each of the two screw holes. A retainer is movably installed at one end of each of the two screw rods, and a clamping roller is rotatably installed inside each of the two retainers.

[0006] Preferably, a motor is installed on the side of the feeding rack, and the motor transmission structure is fixedly connected to the fixing rod on the side of the feeding rack.

[0007] Preferably, the bearing roller is in contact with the surface of the material roller.

[0008] Preferably, a handwheel is installed at the opposite ends of the two screws.

[0009] Preferably, positioning rods are installed on opposite sides of the two retainers, and positioning holes are provided on both support frames. The opposite ends of the two positioning rods pass through the two positioning holes.

[0010] Preferably, sliders are installed on both sides of the fixing frame, and grooves are opened on both sides of the inside of the feeding frame, with the two sliders and the two grooves slidably connected.

[0011] Preferably, a fixing seat is installed at each of the four corners of the bottom of the feeding rack, and the fixing seat is perpendicular to the bottom of the feeding rack.

[0012] Preferably, the two clamping rollers are parallel.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention uses clamping rollers and a support roller to fix the fabric onto the material roller. Two handwheels rotate two screws, which move within the screw holes of two support frames. These screws push two retainers to move in opposite directions, causing the clamping rollers inside the retainers to apply clamping force to the fabric. A motor drives a fixed rod to rotate via a transmission structure, which in turn drives the material roller to rotate. The material roller then rolls up the fabric. During the rolling process, the two clamping rollers tighten the fabric, straightening any wrinkles. The support roller, through the elasticity of two springs, applies pressure to the fabric on the material roller, firmly pressing it onto the roller. This achieves the effect of straightening wrinkles and firmly fixing the fabric onto the material roller during the rolling process, preventing wrinkles from affecting the cutting quality.
