Technical Field

[0001] The utility model relates to the technical field of cloth processing, in particular to a cloth cutting device. Background Art

[0002] In the furniture industry, a series of materials such as fabrics, panels and metal parts are often required for processing, and fabrics usually need to be cut before processing.

[0003] The cloth cutting device of the prior art, such as the utility model patent document with authorization announcement number "CN218521513U" and patent name "A cutting platform for cloth processing", discloses a cloth cutting device, including: a cutting table, on which a unwinding roller for releasing the cloth to be cut and a mounting plate is fixed; a material conveying mechanism, which is arranged on the mounting plate and is used to convey the cloth to be cut; a measuring mechanism, which is arranged on the cutting table and is used to measure the required cutting length; and a cutting mechanism, which is arranged on the mounting plate and is used to cut the measured cloth.

[0004] In the above patent documents, when cutting different fabrics, the tension cannot be adjusted according to the material of the different fabrics, so it is difficult to make different fabrics obtain sufficient tension. When the tension is too small or there is no tension, the edges of the cut fabrics will be unevenly cut or the shapes of the cut fabrics will be different. Utility Model Content

[0005] The utility model aims to solve the technical problems that the cloth cutting device of the prior art mentioned in the background technology cannot adjust the tension according to the material of different cloths when cutting different cloths, so it is difficult to make different cloths obtain sufficient tension. When the tension is too small or there is no tension, the edge of the cut cloth will be unevenly cut or the cut cloth will have different shapes.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A cloth cutting device comprises a support frame, a plurality of horizontal conveying rollers are rotatably provided on the support frame, a guide roller is rotatably provided on the support frame, an adjustment component for adjusting the cloth tension between the guide roller and the conveying roller is provided on the support frame, a first motor is slidably provided on the side of the conveying roller away from the adjustment component, a cutting knife is fixedly provided on the output end of the first motor, a clamping component for clamping the cloth is provided between the cutting knife and the conveying roller, and a pulling component for pulling and clamping the cloth is provided on the side of the first motor away from the clamping component.

[0008] Working principle:

[0009] First, the operator passes the cloth to be cut around the guide roller and winds the cloth around the adjusting component, then places the cloth on the conveying roller and passes through the clamping component and the cutting knife, and finally clamps the cloth on the pulling component.

[0010] When the operator needs to cut the cloth, the pulling component drives the cloth to move. When the cloth to be cut moves to under the cutting knife, the operator starts the clamping component, and the clamping component clamps the cloth, so that the two ends of the cloth cutting part are clamped by the clamping component and the pulling component. Then the operator starts the first motor, and the first motor drives the cutting knife. The operator can make the cutting knife cut the cloth by sliding the first motor. After the cloth is cut, the pulling component drives the cut cloth to be transported outward. When the tension of the cloth needs to be adjusted, the operator can adjust the tension of the cloth through the adjustment component.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] First, an adjustment component is provided, which can adjust the tension of the cloth, so as to adapt to the cloth of different materials to maintain the flatness of the cloth during transportation and reduce the unevenness of the cutting edge of the cloth.

[0013] Secondly, a clamping assembly is provided, which can clamp the cloth. By cooperating with the pulling assembly, the surface of the cloth can be made smoother, which is convenient for the cutting knife to cut the cloth.

[0014] Third, a cutting knife is provided, which can cut the cloth. After the cutting is completed, the cutting knife can be moved to one side of the support frame to avoid contact between the cloth and the cutting knife when the cloth is transported.

[0015] Fourth, a pulling assembly is provided, which can clamp the end of the cloth and pull the cloth to move the cloth to be cut below the cutting knife. When the cloth is cut, the pulling assembly can move to the end of the uncut cloth to facilitate the cutting knife to cut the cloth next time. BRIEF DESCRIPTION OF THE DRAWINGS
