Automatic silk stocking toe sewing machine and use method thereof

Abstract

The invention discloses an automatic silk stocking toe sewing machine and a use method thereof. The automatic silk stocking toe sewing machine comprises a host machine, a movable socking plate, a machine head support, a machine head, a crotch cutting system, a stocking clamping system and the like, wherein the machine head support is independently driven by a lead screw motor, and the machine head support drives the machine head to change the sewing track; because the stocking casing is stationary when the stocking toe is sewn, a movable support drives the machine head to adopt an active sewing mode, thus the rotation speed of the machine head is reduced; and the stocking clamping system is used for clamping the stocking casing, so that the crotch cutting system carries out crotch cutting on the sewn stocking casing. In the invention, through simple man-machine conversation, multiple processes and multiple persons required by stocking toe sewing are changed into one-person operation; when ultra-thin or ultra-thick stockings are sewn, the problems of missed sewing, nonuniform spacing and the like are not generated, and the sewn stockings can accord with the toe arc lines of different crowds; and the crotch cutting is carried out under the state of clamping and tightening the stocking casing, thus the cut is straight and accurate, the artificial crotch cutting error is reduced, the working efficiency is greatly improved, the product quality is guaranteed and the raw materials are saved.

Description

Technical field: [0001] The invention relates to a stocking head sewing machine and its use method, in particular to a stocking head sewing machine which can automatically cut the crotch after sewing on the same head sewing machine, which is not limited by the thickness and raw material of the stockings. Background technique: [0002] With the continuous increase in labor costs and worker mobility and the increasing public demand for socks product quality, socks companies are paying more and more attention to reducing internal circulation costs and reducing artificial unqualified product factors. Updating the process, reducing the process and improving the product efficiency have become the relentless pursuit of the current hosiery industry.

Problems solved by technology

[0003] The stocking head sewing machines of the prior art all adopt the passive sewing method of fixed trajectory, such as the TC720 stocking head sewing machine produced by Japan Takatori Machinery Association. The retractable hollow movable sock board at the bottom, in the sock inlet station and the sock outlet station, the plastic suction port equipped with a fan is automatically connected to the plastic port at the end of the hollow movable sock board, and the tail of the movable sock board is connected to the transmission part of the main machine. The main engine is controlled by a programmable controller to drive them to run; at the sock feeding station, the operator puts the sock tube on the movable sock board, and when the sensor at the sock feeding station senses that the socks have been put on the movable sock board, the sock feeding wheel The outer rubber ring gradually pulls out the toe of the sock sucked into the hollow movable sock tube. When the sock is pulled to the position set by the photoelectric sensor, the alignment action of the sock feeding is completed, and the sock feeding wheel is lifted. Since the main machine is continuous If it is running, if the above series of actions cannot be completed before reaching the next station, the operator will have to pull out the sock tube that has not been fed into the sock and perform the operation again. Therefore, this type of sewing machine is only suitable for sewing thinner shorts. Socks, when used for thick socks, high-elastic socks, and socks with tight tissue structure, due to the increased friction between the sock tube and the sock plate, the operator cannot put on the sock tube within the time of one station, so there will be gaps. The condition of the sock board leads to a decrease in output; when the movable sock board reaches the next station, the suction in the tube is cut off, and the movable head is gradually pushed out of the sock board by the running track of the host machine. The sewing machine is installed in a On the bracket, there is a short slot on the bracket, and a movable pin is installed in the short slot, the pin body of the movable pin can slide in the short slot, the top of the movable pin is slightly higher than the upper plane of the bracket, and there is a piece larger than the width of the short slot The metal plate is fixed on the top of the movable pin to prevent the rack from slipping out of the sho
