High-speed synchronous-belt dial linking machine

Abstract

The invention discloses a high-speed synchronous-belt dial linking machine, comprising a bed, a support mounted on the bed, a dial mounted at the lower end of the support, a synchronous belt drive structure mounted on the bed and the support, a needle swinging drive structure mounted on the support, a cantilever and a needle both mounted on the needle swinging drive structure, a thread take-up drive mechanism mounted on the support, a thread take-up device connected with the thread take-up drive mechanism, and an oil-storage lubricating structure mounted on the periphery of the support. The synchronous-belt drive structure comprises a main shaft mounted on the bed, an auxiliary shaft mounted on the support, and a synchronous belt assembly mounted between the main shaft and the auxiliary shaft; the synchronous belt assembly comprises a first synchronous wheel mounted at the end of the main shaft, a second synchronous wheel mounted at the end of the auxiliary shaft, and a synchronous belt mounted between the first synchronous wheel and the second synchronous wheel; the support is mounted at the edge of the upper end face of the bed, and a longitudinal space is formed between the support and the bed; a reinforced bearing pedestal for supporting the end of the main shaft is arranged on the lateral side of the bed.

Description

Technical field: [0001] The invention relates to the technical field of sewing machines, in particular to a high-speed synchronous belt sewing machine. Background technique: [0002] The sewing machine is one of the important equipment in the wool weaving industry, which is used to sew knitted garment pieces, collars, cuffs, etc. In order to simplify the structure of the seaming machine and improve the working efficiency of the seaming machine, people have made a lot of efforts and achieved great results. But along with the continuous appearance of new chemical fiber fabrics and the constant change of people's needs, higher and higher requirements have been put forward for the performance of the seaming machine, and the original various seaming machine structures have gradually shown their disadvantages. [0003] The transmission structure of ordinary disc sewing machine generally includes a main shaft installed on the vehicle platform and a sub-shaft installed on the brack...

Problems solved by technology

However, with the continuous emergence of new types of chemical fiber fabrics and the continuous changes in people's needs, higher and higher requirements have been put forward for the performance of the sewing machine, and the original structures of various sewing machines have gradually shown their disadvantages.

[0003] The transmission structure of ordinary disc sewing machine generally includes a main shaft installed on the platform and an auxiliary shaft installed on the bracket. The end of the main shaft is equipped with a first bevel gear, and the end of the auxiliary shaft is installed with a second bevel gear. The second bevel gear and the first bevel gear are meshed and interlocked to achieve the driving purpose between the auxiliary shaft and the main shaft, but the second bevel gear and the first bevel gear need to be lubricated, and the wear is relatively large , the noise is also large, which affects the high-speed operation of the sewing machine; moreover, the auxiliary shaft and the main shaft are linked through the bevel gear structure, and the longitudinal interval between them is extremely small, resulting in excessive gap between the lower end of the bracket and the dial. The space of the sheet is small, which makes it inconvenient to operate when sewing thick sweaters or thick materials, which affects work efficiency
