Problems solved by technology
[0002] The structure of the feeding mechanism used in traditional sewing machines is various. At that time, these existing feeding mechanisms were either complex in structure or unreliable in feeding, and the cooperation between the feeding connecting rod and the main shaft in most of them was driven by the tooth fork structure. Such a structure is not only unstable, but also generates a lot of noise during the operation process, and the use and maintenance costs are high, which cannot meet the current low-cost and high-efficiency production requirements, and is also harmful to the working environment of the operators. Especially not suitable for promotion and use in larger workshops

Embodiment Construction
[0012] Below in conjunction with the embodiment shown in the accompanying drawings, the present invention is described in detail as follows:
[0013] as attached figure 1 As shown in the figure, the length direction along the cloth feeding connecting rod 4 is the front and rear direction. The connecting rod type upper sleeve feeding mechanism of the present invention includes a main shaft 1 that is rotatably arranged on the casing, and a cam assembly 2 is provided at one end of the main shaft 1 One end of the tooth-lifting link 3 and one end of the cloth-feeding link 4 are fitted with the cam assembly 2, and the tooth-lifting link 3 and the cloth-feeding link 4 swing back and forth with the rotation of the cam assembly 2 respectively. The other end of the cloth feeding connecting rod 4 drives the cloth feeding shaft 15 to reciprocate through the first cloth feeding crank 5, and the second cloth feeding crank 6 is also arranged on the cloth feeding shaft 15, and the other ...

The invention discloses a connection rod type sleeve joining feeding mechanism. The connection rod type sleeve joining feeding mechanism comprises a main shaft which is rotatably arranged on a case; one end of the main shaft is provided with a cam assembly which is adaptively provided with one end of a feed lifting connection rod and one end of a fabric feeding connection rod; the feed lifting connection rod and the fabric feeding connection rod swing front and back along with the rotation of the cam assembly; one end of the fabric feeding connection rod drives a fabric feeding shaft to rotate to and fro through a first fabric feeding crank; the fabric feeding shaft is also provided with a second fabric feeding crank; the other end of the feed lifting connection rod drives the feed lifting shaft to rotate to and fro through a first feed lifting crank; the feed lifting shaft is also provided with a second feed lifting crank; and a fabric feeding support plate is hinged between the second fabric feeding crank and the second feed lifting crank; and the to-and-fro rotation of the fabric feeding shaft and the feed lifting shaft drives the fabric feeding support plate to swing front andback. The connection rod type fabric feeding connection rod of which one end acts in a way of matching the cam assembly is adopted to ensure that transmission is stable and noise is reduced, so that the working environment of operators is optimized, and the mechanism is more suitable for popularization and use of a large-scale manufacturing shop.
Description
technical field [0001] The invention relates to a sewing machine, in particular to a link-type upper sleeve feeding mechanism used on the sewing machine. Background technique [0002] The structure of the feeding mechanism used in traditional sewing machines is various. At that time, these existing feeding mechanisms were either complex in structure or unreliable in feeding, and the cooperation between the feeding connecting rod and the main shaft in most of them was driven by the tooth fork structure. Such a structure is not only unstable, but also generates a lot of noise during the operation process, and the use and maintenance costs are high, which cannot meet the current low-cost and high-efficiency production requirements, and is also harmful to the working environment of the operators. Especially not suitable for promotion and use in larger workshops. Contents of the invention [0003] The object of the present invention is to provide a link-type upper sleeve feedi...
