Embodiment Construction

[0018] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] like figure 1 As shown, the direct-drive feeding mechanism of the sewing machine includes a horizontal feeding shaft 1, the tooth bracket group room 4 and the cloth feeding dog 5 are installed on the horizontal feeding shaft, the vertical feeding shaft 2, and the tooth picking fork 3 is coaxial with the vertical feeding shaft 2 Placement, and the teeth 6 are tightly bitten by the tooth picking fork.

[0020] Among them, the horizontal feeding shaft and the main shaft are directly driven by the motor to rotate. The horizontal feeding shaft rotates back and forth within a certain range to achieve the purpose of forward and backward feeding. The rotation of the vertical feeding shaft is driven by the rotation of the main shaft, which drives the tooth picking fork to swing up and down, and the teeth move up and down accordingly. In thi...

Abstract

The invention provides an improved sewing machine direct-driving feeding mechanism. The mechanism comprises a motor, a horizontal feeding shaft (1), a vertical feeding shaft (2), a feed dog pickup fork (3), a small assembly (4) for a feed dog frame and a feed dog (5), wherein the feed dog pickup fork (3) is arranged on the vertical feeding shaft (2); the small assembly (4) for the feed dog frame is arranged on the horizontal feeding shaft; and the feed dog (5) is installed on the small assembly (4) for the feed dog frame. In the mechanism, the horizontal feeding shaft (1) is directly driven by a motor, and the vertical feeding shaft is driven by the main shaft motor of the sewing machine. The two motors both can be connected to a computer and are directly programmed to control so as to change the feeding track and parameter of the feed dog. The mechanism has the advantages of stable feeding effect, accurate feeding displacement and convenience in control.

Description

technical field [0001] The invention relates to a sewing machine feeding mechanism, in particular to an accurate feeding mechanism directly driven by a computer-controlled motor. Background technique [0002] There are various types of sewing machines now, such as edge beating machines, overlock sewing machines, embroidery machines, etc. emerge in an endless stream. As we continue to explore, our machines are gradually developing towards intelligence, and we are increasing our efforts in the field of control. But there are still many problems on the mechanical side. [0003] There is a big deficiency in the feeding mechanism of some models of electric sewing machines at present. For example, the feeding displacement needs to be set manually; the feeding transmission device is too complicated; the actual feeding displacement is different from the set displacement due to the inability to overcome the cloth friction. Contents of the invention [0004] Aiming at the deficie...
