Abstract

The utility model provides a pressing-type disc fabric cutting machine which comprises a disc cutter, a fabric piece pressing and discharging adhesive pad, a cutting board, an elastic pad, a sliding shaft, a compression spring, a frame, a handle, a press rod and a connecting rod, wherein the disc cutter comprises a disc and an annular tapered cutter blade raised from the lower margin of the disc, and the fabric piece pressing and discharging adhesive pad is formed by bonding an elastic material in the middle of the cutter blade. When a user pushes the handle, the connecting rod presses the sliding shaft downward to allow the disc cutter which is fixed at the lower end of the sliding shaft to fall down, as a result, the fabric piece pressing and discharging adhesive pad which is raised outside the disc cutter holds a textile material on the cutting board and then the cutting edge of the disc cutter cuts off the fabric fibers. With the technical scheme provided by the utility model, the pressing-type disc fabric cutting machine does not displace during the fabric cutting process, which ensures the accuracy in cutting shape and cutting area and makes the operation easy and rapid. After the handle is released, under the action of the compression spring, the sliding shaft drives the disc cutter to move up to the original position and get ready for the next fabric-cutting process.

Handle divides two parts, and an end is a sheet, and an end pin joint of sheet is on frame, and the other end of sheet is a cylinder, has fixed the handle of handling knob in the screw of cylinder;

Chopping block is fixed on the frame, and the below and the cutting disc that face cutting disc are cooperating and cut the cloth sheet.

Preferred version is that cushion is set below chopping block again, utilizes elasticity to eliminate because the nonparallelism between the cutting disc knife edge and the chopping block end face overcomes because the periphery that the accuracy of manufacture and installation accuracy deficiency cause cuts not in place.

Another program is on chopping block, to be provided with to be no less than 3 screw, and each screw is all connecting screw, and screw is connected on the frame, adjusts the depth of parallelism between the chopping block end face and the cutting disc knife edge with turning screw.

Also having a scheme is that a circle circular groove is set on chopping block, and interior arc diameter and the cutting disc internal diameter of groove are adaptive, make cutting disc fall to cutting off textiles after, the knife edge is direct contacting metal chopping block not, the service life of prolongation cutting disc.

Another scheme is to be merged into a part that calls the handle depression bar to described handle, depression bar, three parts of connecting rod, simplifies the internal structure of an organization, and saves manufacturing cost.

Use push type disk rag cutter of the present invention only to need handle one to push away; Connecting rod is just the sliding axle pressed downward; The cutting disc that is fixed on the sliding axle lower end just falls, and protrusion moves back rubber cushion in the cloth sheet pressure of cutting disc outside and at first pushed down the textiles that is tiled on the chopping block, and and then cutting disc knife edge incision textiles cuts off measuring fiber; Because whippy cloth sheet pressure is moved back rubber cushion and before the cutting disc incision, has just been fixed textiles in large area; So when cutting cloth, can not produce displacement, make cutting profile very accurate with the cutting area, and also simple to operate quick.
