Description

Technical Field

[0001] The utility model relates to a sewing machine, more specifically, it relates to a new type of fur machine. Background Art

[0002] Fur is animal fur tanned with hair, used as clothing material, common fox fur, mink fur, sheep fur and wolf fur, etc. Fur clothing has a long history in my country. The production and processing of fur requires the use of a fur machine to sew it. The commonly used fur machine mainly includes a machine body, a needle bar slidably connected to the machine body, a feed tray located below the needle bar, and pins fixed to the machine body are arranged along the circumference of the feed tray. In addition to sewing fur, the fur machine can also be used to sew various plush toys.

[0003] At present, although the fur machines on the market can sew fur, the space available for sewing is small, the materials that can be sewn are limited, it is difficult or impossible to sew larger materials, the sewing efficiency is low, and the utilization rate of materials is poor. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model aims to provide a new fur machine with a larger sewing space.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of fur machine, including a base, a shell and a machine cover, a crochet mechanism and a sewing mechanism are arranged in the shell, and a motor is also arranged on one side of the shell, the crochet mechanism and the sewing mechanism are connected to the motor through a transmission mechanism, the crochet mechanism includes a crochet rod seat connected to the transmission mechanism and a crochet rod arranged in the crochet rod seat, a cam is also arranged at the connection between the crochet rod seat and the transmission mechanism, the sewing mechanism includes an eccentric wheel connecting rod and a needle rod body, one end of the needle rod body is arranged as a sewing end, the sewing end is arranged on the outside of the shell, and a transmission gear is arranged at the lower end of the sewing end, and the transmission gear outer sleeve is provided with a support for protecting the transmission gear. The bracket seat and the upper end of the sewing end are fixedly connected to the shell through a fixed plate, and the cam is provided with an annular groove for adjusting the movement of the crochet structure. The transmission gear at the lower end of the sewing end is extended by a transmission assembly, and the transmission assembly includes a plurality of gears meshing with each other or a transmission belt connected to the gear transmission. The extension amount of the sewing end is 0.8-1 times the length of the transmission gear, which is used to increase the sewing space of the sewing end, and the fixed plate, bracket seat, crochet rod seat, crochet rod, eccentric wheel connecting rod and needle rod body are extended, and the extension amount of the fixed plate, bracket seat, crochet rod seat, crochet rod, eccentric wheel connecting rod and needle rod body matches the extension amount of the sewing end.

[0006] By adopting the above technical scheme, the transmission component connected with the transmission gear realizes the movement of the needle bar. While maintaining the transmission ratio, the length of the sewing end is increased, the area of ​​the sewing space is increased, the machine can sew larger materials, and the production efficiency is improved. The transmission component is outer-mounted with a bracket seat to improve the safety and prevent the transmission component from falling off. The fixed plate, bracket seat, hook rod seat, hook rod, eccentric wheel connecting rod and needle rod body are extended synchronously to prevent the remaining parts from being insufficient in length to realize the sewing function after the sewing end is extended.

[0007] The utility model is further configured as follows: the inner side of the annular groove of the cam is configured as a first guide groove along the circumferential direction, and the outer side of the annular groove is configured as a second guide groove along the circumferential direction, the distances between the first and second guide grooves are the same, and a plurality of arc surfaces with different curvatures are provided in the guide groove, and adjacent arc surfaces are configured tangentially, so as to maintain the motion trajectory of the crochet structure during the transmission process.

[0008] By adopting the above technical solution, the annular groove arranged on the inner side of the cam realizes the vertical movement of the hook mechanism to complete the hook action. The distances between the guide grooves are the same to prevent the machine from falling off or getting stuck during the transmission process and causing damage to the machine. The guide groove includes a number of arc surfaces with different curvatures. The hook assembly slides along the arc surface of the guide groove during the transmission process to maintain the movement trajectory of the hook assembly and prevent the change of the running trajectory of the hook assembly after extension, which leads to a decrease in the qualified rate of the product. The adjacent arc surfaces are tangently arranged to make the hook assembly move smoothly and the finished product after sewing is more beautiful. BRIEF DESCRIPTION OF THE DRAWINGS
