Automatic bottom line changing device of computer embroidery machine

Abstract

The invention discloses an automatic bottom line changing device of a computer embroidery machine, which can automatically change a shuttle peg of a bottom line rotating shuttle in a mechanical mode so as to further improve the production efficiency and the automation degree of the computer embroidery machine and lighten the labor intensity of workers. Therefore, a mounting plate is fixedly arranged on a machine frame; one end of the mounting plate is close to a rotating shuttle box, while the other end of the mounting plate is fixedly provided with a shuttle peg bin; two right angle type guide plates, which have the same shape and are opposite to each other, are arranged in the mounting plate; the outer side of the lower lateral surface of a horizontal section of the guide plate is provided with a sliding block; the upper part of the sliding block is provided with a rotary block and a positioning rotary block; the upper end face of the positioning rotary block is a semicircle surface, two lateral surfaces of the positioning rotary block are planes parallel to each other, and the positioning rotary block contact a limit track formed by the lower lateral surfaces of the horizontal sections of the two guide plates; a cylinder and a shuttle peg paw are vertically arranged on the left lower part of the rotary block; and the sliding block performs horizontal linear reciprocating motions with the help of a guide rod and a belt driving structure, thereby making the shuttle peg paw perform circular track motions between the shuttle peg box and the shuttle peg bin to realize the bottom line automatic changing.

Description

technical field [0001] The invention relates to the technical field of computerized embroidery bobbin thread changing, in particular to an automatic bobbin thread changing device for a computerized embroidery machine. Background technique [0002] So far, the computerized embroidery machines used in China generally do not have the function of automatically replenishing the bottom thread. The bobbin thread of the embroidery machine is wound on the thread core contained in the bobbin core. When the bobbin thread is used up at a certain head of the machine, it must be stopped and manually operated to remove the bobbin thread from the bobbin case. Replace the bobbin with a new one with the bobbin fully wound with the bobbin thread, or take out the empty bobbin from the bobbin and replace it with a full bobbin. Simultaneously, the rotary hook box is generally all located under the worktable, and it is very inconvenient to replace the action. Calculated on the basis of each comp...
