Clamping device for bag opening machine

Abstract

The invention relates to the technical field of sewing machines, and provides a clamping device for a bag opening machine. The clamping device includes a controller, a fixing support, a first driving mechanism, a second driving mechanism, a first pressing pawl mechanism, a second pressing pawl mechanism, a moving base, a fixing base, a first connection rod, a second connection rod, a third connection rod, and a pressing plate; the first pressing pawl mechanism can lift / press the pressing pawl so as to arrange the pressing pawl on an upper surface of the moving base by matching an arc portion and an arc groove and matching a semi-circular shaft and a semi-circular groove; the second driving mechanism can lift / press the pressing pawl of the pressing pawl plate through the third connection rod and is fixed on an upper surface of the fixing base; and the first driving mechanism and the second driving mechanism are connected to and are controlled by a controller. The problem that the clamping devices of the conventional bag opening machines are large in labor intensity, and are low in production efficiency can be solved.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a clamping device for a bag opening machine. Background technique [0002] During the processing of suits and other clothing, opening the bag is an essential process. By opening the bag, a pocket is formed at a specific position of the garment, so that it is convenient to carry small items such as mobile phones and wallets. The conventional method is to process the garment parts, pocket flaps, pocket cloth and inserts separately first, then align the pocket cloth and garment parts with the position of the insert lines, and assemble the garment parts, pocket covers, pocket cloth and inserts. The bag opening machine came into being. As a garment processing equipment, bag opening machine plays an important role in modern garment production. In the prior art, a large presser foot for assisting sewing is provided on the sewing table of the bag opening machine, including a pr...

Problems solved by technology

However, in the process of clothing processing, in order to meet the market demand, the styles of clothing are designed in a variety of ways, and the size of the pockets also changes with the design. When sewing on the bag opening machine, the original presser foot on the bag opening machine cannot press the pocket. As a result, it is necessary to add a process to fix the pocket cloth during processing, because the added process increases the processing time, reduces the output, and increases the production cost of the enterprise.

Therefore, a clamping device specially used to clamp the pocket cloth is set on the workbench of the bag opening machine, such as Chinese Patent No.: 201120560238.1, which discloses a special clamp for pocket cloth of the bag opening machine, including wide bead, narrow bead, Connecting rods and sliding grooves, the wide bead is concave with equal length on both sides, the inner bottom of the concave is semicircular, and the outside of the concave is connected to the narrow bead through the connecting rod; the narrow bead is concave with one side length smaller than the other, and the concave The bottom edge is a straight edge; there is a sliding groove in the middle of the connecting rod. Although this invention meets the design and processing requirements of the existing style pockets and reduces the processing time, it uses manual lifting and pressing of the clamps, and the labor intensity of the operators is very high. Large, the production efficiency is not high enough, and there is a risk that the operator's fingers will be injured by the fixture
