Description

Cloth cutting machine

technical field

The invention relates to a cutting machine, in particular to a cloth cutting machine.

Background technique

When making and producing textile products, it is necessary to cut the entire piece of fabric according to the required size and specifications to prepare for the next step of production and processing. The traditional method is to wind the cloth with a winding frame, and control the size and length of the cloth cutting through the diameter of the winding frame. This method is simple to operate and relatively fast in efficiency, but the size of the cut cloth Due to the large error, the cloth winding is due to the thickness of the cloth itself, and the length of the outer layer of cloth will gradually increase compared with the length of the inner layer of cloth after cutting, so that the actual length of each cloth is different. Theoretical error is already relatively obvious, but in the process of actual operation and production, the actual error will be even greater. At the same time, the production needs to stop and cut after each winding, and then continue to operate. Such a large pause makes it difficult to form a streamlined and continuous production. Reduced overall work efficiency.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are explanations of the present invention and the present invention is not limited to the following examples.

As shown in Figure 1, the cloth cutting machine of the present invention comprises a bracket 1, a cloth roll 2, a cloth guide mechanism 3, a cloth cutting mechanism 4 and a control box 5, and the cloth roll 2 is rotatably arranged on one side of the support 1, and the cloth is cut The cloth mechanism 4 is arranged in the middle of the support 1 , and the cloth guiding mechanism 3 is arranged on both sides of the cloth cutting mechanism 4 . One side of the cloth reel 2 is provided with a cloth guide roller 6, and the cloth guide roller 6 is rotatably arranged on the frame 1, and the control box 5 is fixed on the frame 1. The cloth guide mechanism 3 is composed of multiple groups of cloth transmission shafts arranged on both sides of the cloth cutting mechanism 4. Each group of cloth transmission shafts includes two rollers 7 arranged up and down. The rollers 7 are arranged horizontally and rotated on the brackets 1 on both sides. , the cloth transmission shaft is driven by the motor 8 and the upper and lower two rollers 7 of each group of cloth transmission shaft rotate in opposite directions.
