Description

Technical Field

[0001] The utility model belongs to the technical field of sewing equipment and relates to a material pressing and transferring device and a pocket pasting machine. Background Art

[0002] In the process of sewing clothes, pockets are often needed to be sewn. Before sewing the pockets, three sides of the pocket cloth need to be folded, and then the three sides of the pocket cloth are sewn with other fabrics to form pockets.

[0003] During the sewing process, the edge of the pocket cloth needs to be tightly attached to other fabrics. Therefore, a clamping structure is needed, such as a feeding mechanism for a pocket sticking machine provided in application No. 201220507371.5, which uses an auxiliary presser foot and an external presser foot to clamp the material together to fix the bag piece (pocket cloth) to the fabric.

[0004] The disadvantage of the prior art is that after the pocket cloth is closely attached to other cloths, it is difficult to refold it, which has certain limitations. Summary of the invention

[0005] The utility model aims at the above problems existing in the prior art and provides a material pressing and shifting device. The technical problem to be solved by the utility model is: how to refold pocket fabric.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A material pressing and shifting device comprises a mounting seat, characterized in that a base is slidably connected to the mounting seat, a left telescopic arm, a middle telescopic arm and a right telescopic arm are movably connected to the base, a clamping plate 1 is arranged on the outer side of the left telescopic arm, a clamping plate 2 is arranged on the outer end of the middle telescopic arm, a clamping plate 3 is arranged on the outer side of the right telescopic arm, a driving member 1 for driving the base to move up and down is arranged on the mounting seat, and a driving member 2 for driving the left telescopic arm and the right telescopic arm to move towards or away from the middle telescopic arm is also arranged on the base.

[0008] The working principle is: the material pressing and shifting device is used in conjunction with the folding device and the tongue plate telescopic device.

[0009] The pocket pasting machine includes a workbench. When in use, a piece of body fabric is placed on the workbench, the entire tongue plate retractable device extends from the top of the workbench, the tongue plate is located above the body fabric, and the driving member drives the pressing plate 1 and the pressing plate 2 to move away from each other, and the pressing plate 1 and the pressing plate 2 are stretched apart, and then the pocket fabric is buckled on the pressing plate 1 and the pressing plate 2, and the three adjacent sides of the pocket fabric extend downward respectively. After the folding device folds the corresponding sides of the pocket fabric toward the direction close to the tongue plate retractable device, the folding device and the tongue plate retractable device descend together, so that the three edges of the pocket fabric are in contact with the body fabric and are pressed against the workbench by the tongue plate retractable device. After the folding is completed, the folding device leaves the tongue plate retractable device.

[0010] After that, the material pressing and transferring device moves over until the pressing plates 1, 2 and 3 are located above the pocket fabric, and then the driving member 1 drives the base to move downward, and the three pressing plates are pressed down with the base. After being pressed into place, the three pressing plates rest against the workbench, and the driving member drives the pressing plates 1 and 2 to move closer to each other, leaving space (after the pressing plates 1 and 2 are contracted, there is space between the pressing plates 1 and 2 and the corresponding edges of the pocket fabric, respectively). Then, the driving member 2 drives the left telescopic arm and the right telescopic arm to move closer to the middle telescopic arm (at the same time, the driving member 1 drives the base to jump up to a certain height, so that the bottom of each pressing plate is higher than the thickness of the fabric on the tongue plate, that is, jump The height of the pocket fabric is greater than the thickness of the tongue plate and the fabric combined), and at the same time, the middle telescopic arm retracts inward, and the pressing plates 1, 2, and 3 move inward. When the left telescopic arm and the right telescopic arm move closer to the middle telescopic arm, the pressing plates 1, 2, and 3 form an inner pressure frame, and the pressing plates 1, 2, and 3 press (and fold) each edge of the pocket fabric (three edges in total), and the bottom of the three edges of the pocket fabric exposes the edges of the fabric to be sewn. After that, the entire tongue plate telescopic device retracts, and the material pressing and moving device moves to the needle of the pocket sticking machine. The needle sews the edge of the fabric to complete the sewing of the three-dimensional pocket. After that, the driving member 1 drives the base 1 to move upward, and the driving member 2 drives the left telescopic arm and the right telescopic arm away from the middle telescopic arm.

[0011] After the pocket fabric is folded for the first time, the driving member 2 of the material pressing and transferring device drives the left telescopic arm and the right telescopic arm to move closer to the middle telescopic arm, so that the pressing plates 1, 2 and 3 are combined into an inner pressing frame, and the pressing plates 1, 2 and 3 are respectively refolded on each edge of the pocket fabric (a total of three edges) to produce the fabric edges that need to be sewn, thereby efficiently and quickly sewing a three-dimensional pocket.

[0050] like Figure 1 As shown, in this embodiment, the driving member three 25 includes a cylinder three, and the cylinder three is mounted on the mounting seat 1. The piston rod of the cylinder three is connected with a connecting member two 26, and the connecting member two 26 is fixed to the external pressure frame 23. The external pressure frame 23 is provided with a slider seven 27, and the mounting seat 1 is provided with a vertically extending guide rail seven 28, and the slider seven 27 is slidably connected to the guide rail seven 28.

[0051] The cylinder three drives the connecting piece 26 to move up and down, and the connecting piece 26 drives the external pressure frame 23 to move up and down.

[0055] Embodiment 2

[0056] The structure and principle of this embodiment are basically the same as those of the first embodiment, except that Figure 4 As shown, a corner limit plate 30 is respectively provided on one side of the clamping plate 1 6 and one side of the clamping plate 3 8, the corner limit plate 30 is parallel to the clamping plate 2 7, a gap is provided between the end of one corner limit plate 3 and the end of the clamping plate 1 6, a gap is provided between the end of the other corner limit plate 30 and the end of the clamping plate 3 8, and the bottoms of the clamping plates 1 6, 2 7 and 3 8 respectively have flanges 35.

[0057] When the left telescopic arm 3 and the right telescopic arm 5 move toward the middle telescopic arm 4, there is a gap between the end of the second pressing plate 6 and the end of one corner stop plate 30, and there is also a gap between the end of the second pressing plate 8 and the end of the other corner stop plate 30. The corner stop plate 30 can first smooth the pocket fabric to ensure that the corner position is sharp when sewn, thereby improving the sewing quality. Specifically, the stem position is released (must be released, otherwise it is difficult to shrink inward) through the above two gaps (the gap between the end of the corner stop plate 30 and the end of the second pressing plate 6, and the gap between the end of the corner stop plate 30 and the end of the third pressing plate 8), and then the stem position is further retracted inward through the flange 35 between the two adjacent pressing plates (pressing plate 1 6 and pressing plate 2 7 and pressing plate 2 7 and pressing plate 3 8) to prevent the stem position from being sewn to the bottom fabric (body fabric) during sewing.

[0058] Preferably, at least one flange 35 extends outward to form a stem-retracting portion, which can prevent the stem position from affecting sewing.

[0059] Preferably, two adjacent flanges 35 extend outward to form a stem-retracting portion, and the two stem-retracting portions can be in contact with each other or have a gap therebetween. When the pressing plate 1 6, the pressing plate 2 7 and the pressing plate 3 8 are closed together to form an inner pressing frame, the two stem-retracting portions are in contact with each other or have a gap therebetween. When the two stem-retracting portions are in contact with each other, there is no gap therebetween. When there is a gap between the two stem-retracting portions, the gap is not greater than the width of the stem position. In either case, the stem-retracting portion can play a role in hooking the stem, bringing a better stem-retracting effect.

[0060] like Figure 4 As shown, in this embodiment, each side of the outer pressure frame 23 is respectively provided with an adjustment plate 31, and the outer end of the adjustment plate 31 is installed with a pressing piece 32. The outer end of the adjustment plate has a strip groove 33, and a plurality of mounting holes 34 are opened on the pressing piece 32. The mounting holes 34 are distributed along the length direction of the pressing piece 32.

[0061] The pressing piece 32 is used to press the body fabric and plays a good positioning role. The pressing piece 32 can be conveniently fixed on the adjustment plate 31 by installing screws on the mounting holes 34. The screws can be threadedly connected to different mounting holes 34. The mounting position of the pressing piece 32 can be adjusted as needed. The screws can move in the strip grooves 33, which greatly improves the convenience of installation.

[0062] The utility model also provides a pocket sticking machine, which comprises any one of the above-mentioned material pressing and transferring devices.

[0063] The specific embodiments described herein are merely examples of the spirit of the present invention.
