Description

Technical Field

[0001] The utility model belongs to the technical field of clothing machinery, and in particular relates to a bidirectional cloth cutting device of a cloth spreading machine. Background Art

[0002] The cloth spreading machine is a common equipment in the field of garment processing, which replaces manual labor to realize automatic cloth spreading. The cloth spreading machine is a machine that aligns and lays the rolled seamless materials layer by layer on the cutting table for cutting. It mainly includes a walking mechanism, a cloth feeding mechanism, a cutting mechanism and an electrical control mechanism. The cutting device of the cloth spreading machine belongs to the cutting mechanism, which mainly drives the cutting knife to cut the cloth through the walking motor.

[0003] As far as the prior art is concerned, the cloth spreading machine only cuts the cloth at the unit end position, for example, when the cloth is spread forward from right to left to a predetermined position, the cloth is cut off. In this direction, the cloth can always be in the position where the disc knife as the moving knife and the fixed bottom blade as the static knife are located, so the cloth can be cut off smoothly. In the above process, it is difficult to cut the cloth because the cloth cannot be placed between the disc knife and the fixed bottom blade when spreading the cloth in the reverse direction. If the problem of being unable to cut off caused by reverse spreading cannot be solved, the cloth spreading machine can only operate in one direction, which is bound to affect the spreading efficiency. For this reason, the applicant has made a useful design, and the technical solution to be introduced below is produced in this context. Utility Model Content
