Umbrella fabric processing and cutting device

Abstract

The invention discloses an umbrella fabric processing and cutting device, and relates to the technical field of umbrella fabric cutting devices, the umbrella fabric processing and cutting device comprises a machine tool and a cutting mechanism arranged on the machine tool and used for cutting umbrella fabric, and the cutting mechanism comprises a mounting power part, a plurality of groups of telescopic parts, a cutting part, a driving gear, a plurality of driven gears, a suspension rotating block, a plurality of expansion rods and an expansion dispersion wheel. Through the use of the cutting device, cloth can be directly cut into regular circles, then the circular cloth is trimmed into triangles or sectors, the step of cutting the cloth into rectangles can be omitted, more time is saved, meanwhile, the size of the cutting mechanism can be adjusted according to the size of an umbrella, the cutting mechanism is more flexible and high in applicability, and through the use of the positioning mechanism, the cutting efficiency is improved. According to the cloth cutting device, the position can be limited according to the size of cut cloth, and the situation that the cloth is curled in the cloth cutting process, accidents occur in cloth cutting, the cloth is wasted, and meanwhile a cutting tool bit is possibly damaged is avoided.

Description

technical field [0001] The invention belongs to the technical field of umbrella surface cutting devices, in particular to a processing and cutting device for umbrella surfaces. Background technique [0002] Umbrella is a tool that can provide a shady environment or shelter from rain, snow, sunlight, etc. China is the first country in the world to invent umbrellas. Umbrellas are an important creation of Chinese working people. They were called "簦" at that time. It can be said that umbrellas are closely related to people's lives, from the yellow umbrellas used by the emperor to travel, down to the rain shelter tools of the common people. Modern umbrellas are usually made of stretchable fabrics, and other materials and winding threads that can be used as skeletons. When making an umbrella, the processing of the umbrella surface first needs to cut the umbrella cloth into long strips, then cut it into triangles, and then sew the triangles into a complete umbrella surface.

Problems solved by technology

[0003] Umbrella cloth is an important part of the umbrella. At present, the operation of cutting the umbrella cloth into triangles is as follows: the worker first folds the strips of suitable size from top to bottom into a stack, and then presses them with a triangular mold of suitable size. At one end of the upper surface of the stack of cloth, press the cloth tightly, and then manually cut around the mold with a knife. After cutting once, move the position of the mold along the long strip of umbrella cloth until the stack of All the cloth is cut into triangles, which is labor-intensive and inefficient for workers to cut manually
