Description

Technical Field

[0001] The utility model relates to the field technology of bag piece sewing, in particular to a bag piece frame pressing device and bag piece sewing equipment. Background Art

[0002] like Figure 7 As shown, the bag piece 1 is usually a trapezoid with a larger upper part and a smaller lower part. After the bag piece is folded, a small amount of fabric will be exposed at the end of the folded corner of the bag piece above the open end 2 of the bag piece, roughly as shown in FIG. Figure 8 As shown; the frame pressing device moves the folded bag piece to the bottom of the sewing machine, and then sews it on the automatic sewing machine. Figure 9 As shown, the exposed portion 3 affects the aesthetic appearance of the bag opening.

[0003] For orders with higher processing quality requirements, the protruding part 3 is folded inwards manually, such as Figure 10 As shown, the method is then sewn. This method can solve the problem of the protruding part affecting the aesthetics of the bag opening. However, it relies on manual folding of the material and is not suitable for the automatic frame pressing and material moving method of the automatic sewing machine. The folded material can only be placed manually under the sewing machine head, and the protruding part 3 is folded inward before sewing. This will reduce the processing efficiency. However, since the bag fabric is folded inward, the thickness of the local part 4 is increased. On the one hand, it will lead to less than ideal flatness of the corner of the bag opening. On the other hand, for jeans, it is necessary to add rivets at the corner of the pocket opening for reinforcement (to avoid excessive stress at the seam of the pants and tearing). The increased local thickness will affect the setting of the rivet, making it difficult to firmly set the rivet on the jeans.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0040] The operation flow of a bag sewing machine is roughly as follows:

[0041] 1. Place the bag 1 on the bag folding station 101 (usually the large piece is located at the bottom of the bag). Figure 7 As shown, the bag 1 is folded by the bag folding device 200, and the bag after folding is roughly as shown in FIG. Figure 8 As shown; the bag folding device is reset;

[0042] 2. The material moving drive device 202 drives the bag sheet pressing frame device 201 to move to the bag sheet folding station 101, the pressing frame 20 descends to press the large piece, the bag sheet presser foot 51 descends to press the bag sheet, and the bag sheet side limit pieces 24 are limited to the left and right sides of the bag sheet (further, a bag sheet front end limit piece 231 can be provided on the front side press strip 23 to limit the front end of the bag sheet, and the front end limit piece 231 is connected to an adjusting piece to adjust the front and rear position), the bag sheet folding angle flattening piece 41 moves forward to push the protruding part 3, and the protruding part 3 and the side edge of the bag sheet where it is located will gradually squeeze inward until they are all pressed against the inside of the bag sheet opening end 2, so that the end of the bag sheet side folding angle is flush with the bag sheet opening end 2, and the pushing state is maintained all the time;

[0043] 3. The material moving drive device 202 drives the bag sheet pressing device to move the material (e.g. bag sheet and large sheet) from the bag sheet folding station 101 to the sewing station 102. The sewing device 300 sews the bag sheet to the large sheet. During the sewing process, the bag sheet folding angle flat plate 41 always maintains a pushing state. Figure 11 and Figure 12 As shown, it is ensured that the bag piece after sewing does not have the problem of exposed parts affecting the appearance in the traditional technology. Since the folded corner of the bag piece abuts the flat piece 41, the exposed part 3 and the side of the bag piece where it is located will gradually be squeezed inward, and there is no problem of local thickness increase, which does not affect the subsequent rivet setting process.

[0044] 4. After sewing is completed, the material transfer drive device 202 drives the bag piece pressing frame device to move the materials (for example, bag pieces and large pieces) from the sewing station 102 to the unloading station 103. The materials fall from the drop hole 104 onto the receiving table 400. The receiving table 400 rotates according to the set parameters, so that the materials are stacked one by one along the circumference on the receiving table 400 and placed neatly, which is conducive to subsequent operations.

[0045] The automatic driving part in this embodiment can be driven by a cylinder or a motor.

[0046] The design focus of the present utility model is that it is mainly achieved by arranging two groups of bag corner flattening mechanisms 40 with left and right spacing on the pressing frame 20; the bag corner flattening mechanism 40 includes a bag corner flattening piece 41 and a Y-axial drive unit 42, and the Y-axial drive unit 42 drives the bag corner flattening piece 41 to move forward and backward along the Y-axial direction, and utilizes the bag corner flattening mechanism 40 to push the side corner end of the bag at the open end of the bag, so that the side corner end of the bag is flush with the open end of the bag, taking into account the needs of automated production and high sewing quality requirements.

[0047] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention.
