Computerized embroidery machine automatic baseline replacing apparatus

Abstract

The invention relates to a computerized embroidery machine automatic baseline replacing apparatus. The apparatus comprises an embroidery machine snatch fork overturning mechanism, an automatic bobbin case replacement mechanism and a bobbin case bin mechanism for storing standby bobbin cases, the body of the cylinder 1 of the automatic bobbin case replacement mechanism is fixedly installed on a support plate, the support late and a lining block are fixedly installed on a transmission plate, and the support plate, the lining block and the transition plate are connected to form an L-shaped rigid body. The apparatus has the following advantages: an artificial bobbin case replacement process is replaced by a mechanical automatic bobbin case replacement principle, so a worker fills the baseline-wound bobbin cases into the bobbin case bin for storing the standby bobbin cases, a single-board computer controls the automatic baseline replacing apparatus to complete a series of motions when the baseline of the embroidery machine is exhausted to realize the automatic bobbin case replacement, and the bobbin cases in the bobbin case bin for storing the standby bobbin cases can be replaced when the embroidery machine is not in a shutdown state, thereby the down time of the embroidery machine is reduced; one-key automatic bobbin case replacement is realized, so the work intensity is reduced; and batch release is realized, so the time is saved, and the management is convenient.

Description

technical field [0001] The invention relates to a computer embroidery machine, in particular to an automatic bobbin thread changing device for a computer embroidery machine. Background technique [0002] The computerized embroidery machine is a mechatronics product developed on the basis of the sewing machine, wherein the rotary hook body is an important part of the embroidery machine, which consists of a rotary hook, a bobbin case and a bobbin full of bottom threads. Its function is to use the rotation of the rotary hook to form stitches on the surface of the fabric; due to the limited volume of the entire rotary hook, the outer diameter of the ordinary bobbin of an embroidery machine is only 21*8.5mm, and the length of the bobbin thread that can be wound is generally Around 60m. Therefore, when the embroidery machine is working, generally a bobbin full of bobbins can be used up in about 30 minutes. When the bobbin thread is used up, the embroidery machine needs to be stop...

AI Technical Summary

Problems solved by technology

Therefore, when the embroidery machine is working, generally a bobbin full of bobbins can be used up in about 30 minutes. When the bobbin thread is used up, the embroidery machine needs to be stopped first, and then the bobbin thread is manually changed. The machine downtime is too long, the workers' work intensity is high, the work efficiency is low, and the consequences of low output

Especially in today's embroidery machines, the number of heads is increasing, and
