Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to an automatic bag opening machine and its pressure plate structure. Background Technology

[0002] In garment manufacturing, pocket-opening machines are essential auxiliary processing machinery, mainly used to create pockets in specific locations on garments. These pockets are for users to place small items such as mobile phones, wallets, and keys. The processing of the pocket opening requires cutting, folding, shaping, and sewing the garment fabric at the location where the pocket will be produced.

[0003] Typically, a zipper and fabric are fed into a pocket-making machine, which then sews them together to form a pocket. Therefore, transporting the fabric used for pocket linings is an essential step. With existing pocket-opening machines, the fabric is prone to wrinkling after removal, leading to defective pockets and affecting product quality. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides an automatic bag opening machine and its pressure plate structure. To solve the above-mentioned technical problems, this utility model provides the following technical solution.

[0005] An automatic bag opening machine and its pressure plate structure include a main frame of the bag opening machine, on which a moving mechanism, a pressure plate mechanism, a cutting mechanism, a circulating feeding mechanism, at least two material plates for placing fabric and for repeated use, a folding knife mechanism and a sewing machine are installed; The moving mechanism is mounted on the main frame and can move back and forth and left and right. The folding knife mechanism and the pressure plate mechanism are mounted on the moving mechanism and the moving mechanism drives the folding knife mechanism and the pressure plate mechanism to move back and forth and left and right. The pressure plate mechanism is used to fix the fabric and zipper, and is mounted on the moving mechanism in a height-adjustable manner. The pressure plate mechanism can move to remove the material plate containing the fabric. The main frame is equipped with a fabric ejection mechanism, and the bottom of the pressure plate mechanism is equipped with a fabric limiting mechanism that works in conjunction with the fabric ejection mechanism. When the pressure plate mechanism grabs the material plate, the fabric ejection mechanism first moves to hold the fabric in place, the fabric limiting mechanism moves to limit the fabric, and then the fabric ejection mechanism retracts.

[0006] Furthermore, the fabric ejection mechanism includes a fixed base fixed in the main frame, a cylinder installed on one side of the fixed base, and a fabric ejection component installed on the cylinder. The cylinder drives the fabric ejection component to move and hold the fabric in place.

[0007] Furthermore, the fabric support includes a mounting plate mounted on the cylinder and at least two push rods protruding from the mounting plate, which extend longitudinally through the table surface of the main frame to support the fabric.

[0008] Furthermore, the fabric limiting mechanism includes a cylinder and a pull rod installed on the pressure plate mechanism, as well as clamping members located at the bottom of the pressure plate mechanism and on both sides. The clamping members are fixed to the pull rod. The extension and retraction of the cylinder drives the pull rod to move, thereby driving the clamping members to move to clamp the fabric.

[0009] Furthermore, a guide portion is provided between the clamping member and the pressure plate mechanism, and the clamping member moves along the trajectory of the guide portion.

[0010] Furthermore, the guide portion includes a guide groove on the pressure plate mechanism and a protruding guide block on the clamping member. The width of the guide block is adapted to the width of the guide groove, and the guide block moves within the guide groove when the clamping member moves back and forth.

[0011] Furthermore, the pressure plate mechanism includes a longitudinal connecting plate, a transverse pressure plate, and a zipper limiting plate that can be raised and lowered by a cylinder on the pressure plate. One end of the connecting plate is mounted on the moving mechanism, and the other end of the connecting plate is connected to the pressure plate by a cylinder. The raising and lowering of the pressure plate is achieved by the extension and retraction of the cylinder. A pressure plate is provided at the bottom of the pressure plate, and a cylinder is provided on the pressure plate connected to one end of the pressure plate. The fabric is clamped between the pressure plate and the material plate, and the zipper is clamped between the pressure plate and the zipper limiting plate.

[0012] Furthermore, the pressure plate is provided with a lower seam groove, the zipper limiting plate is provided with an upper seam groove corresponding to the lower seam groove, and the zipper limiting plate is provided with a toothed strip placed in the upper seam groove. The sewing machine passes through the upper seam groove and the lower seam groove to sew the zipper and the fabric.

[0013] Furthermore, the folding knife mechanism includes a folding knife mounting base, a drive motor, a movable front folding knife, a rear folding knife, and side folding knives on both sides. The drive motor drives the folding knife mounting base to rise and fall through the meshing of gears and racks, and the cylinder pushes the front folding knife, rear folding knife, and side folding knife to fold the fabric to form a bag lip.

[0014] Furthermore, the circulating feeding mechanism includes a transverse cylinder and guide rail, a longitudinal cylinder and guide rail, a support base, and a clamp mounted on the support base for gripping the material plate. The transverse cylinder drives the support base to move left and right, and the longitudinal cylinder drives the support base to move back and forth.

[0015] Compared with the prior art, the beneficial effects that this utility model can achieve are: The main frame of this utility model is equipped with a fabric ejection mechanism, and the bottom of the pressure plate mechanism is equipped with a fabric limiting mechanism. When the pressure plate mechanism grabs the material plate, the fabric ejection mechanism first moves to hold the end of the fabric, and then the fabric limiting mechanism moves to limit the fabric. Subsequently, the fabric ejection mechanism retracts, and the pressure plate mechanism picks up the fabric and moves. The fabric limiting mechanism can effectively prevent the fabric from sagging, ensuring that the fabric remains flat when sewing the zipper and the fabric, avoiding wrinkles in the produced pockets, and ensuring good production quality.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-7As shown, an automatic bag opening machine and its pressure plate structure include a main frame 1. The main frame 1 is equipped with a moving mechanism 2, a pressure plate mechanism 3, a cutting mechanism 8, a circulating feeding mechanism 5, at least two material plates 7 for placing fabric and used repeatedly, a folding knife mechanism 4 for folding the fabric to form a bag lip, and a sewing machine 6. The moving mechanism 2 is mounted on the main frame 1 and can move back and forth and left and right via a cylinder. The folding knife mechanism 4 and the pressure plate mechanism 3 are mounted on the moving mechanism 2, and the moving mechanism 2 drives the folding knife mechanism 4 and the pressure plate mechanism 3 to move back and forth and left and right. The pressure plate mechanism 3 is used to fix the fabric and zipper, and is mounted on the moving mechanism 2 in a height-adjustable manner. The pressure plate mechanism 3 moves to remove the material plate 7 containing the fabric, then moves to the cutting mechanism 8 to cut the fabric using laser cutting. The folding knife mechanism 4 descends, folds the fabric at the cut to form a bag lip, and retracts. Then, a zipper is placed on the pressure plate mechanism 3, and the pressure plate mechanism 3 moves below the sewing machine 6 to sew the fabric and zipper together.

[0027] The main frame 1 is equipped with a fabric ejection mechanism 9. The bottom of the pressure plate mechanism 3 is equipped with a fabric limiting mechanism 10 that works in conjunction with the fabric ejection mechanism 9. When the pressure plate mechanism 3 grabs the material plate 8, the fabric ejection mechanism 9 first moves to hold the fabric in place, and then the fabric limiting mechanism 10 moves to limit the fabric. Subsequently, the fabric ejection mechanism 9 retracts. After the pressure plate mechanism 3 removes the fabric, it needs to move. The fabric limiting mechanism can effectively prevent the fabric from sagging, ensuring that the fabric remains flat when sewing the zipper and the fabric, avoiding wrinkles in the produced pockets, and ensuring good production quality.

[0028] The fabric ejection mechanism 9 is concealed inside the main frame 1. The fabric ejection mechanism 9 includes a fixed base 11 fixed within the main frame 1, a cylinder mounted on one side of the fixed base 11, and a fabric ejector 12 mounted on the cylinder. The cylinder drives the fabric ejector 12 to move up and down to hold the fabric in place. The fabric holding member 12 includes a mounting plate 13 mounted on the cylinder and at least two push rods 14 protruding from the mounting plate 13. When the pressure plate mechanism 3 moves onto the material plate 7 containing the fabric, it descends to grab the material plate 7. At this time, the push rods 14 move upward through the table surface of the main frame 1 to hold the end of the fabric in place. Subsequently, the fabric limiting mechanism 10 moves forward to limit the end of the fabric, preventing it from sagging. The fabric ejection mechanism 9 needs to hold the fabric from below, and the fabric limiting mechanism 10 needs to move forward to successfully limit the fabric.

[0029] The fabric limiting mechanism 10 includes a cylinder and a pull rod 15 mounted on the pressure plate mechanism 3, and clamping members 16 located at the bottom and on both sides of the pressure plate mechanism 3. The clamping members 16 are fixed to the pull rod 15 by screws. The extension and retraction of the cylinders on both sides pushes the pull rod 15 to move, thereby driving the clamping members 16 to move laterally to clamp the fabric, so that the end of the fabric is clamped between the clamping members 16 and the pressure plate mechanism 3.

[0030] like Figure 3 , Figure 4 As shown, the number of clamping elements 16 can be two or more.

[0031] A guide portion 17 is provided between the clamping member 16 and the pressure plate mechanism 3. The clamping member 16 moves along the trajectory of the guide portion 17, which guides the movement of the clamping member 16. The guide portion 17 includes a guide groove 18 on the pressure plate mechanism 3 and a protruding guide block 19 on the clamping member. The width of the guide block 19 is adapted to the width of the guide groove 18. When the clamping member 16 moves back and forth, the guide block 19 moves within the guide groove 18.

[0032] The pressure plate mechanism 3 includes a longitudinal connecting plate 20, a transverse pressure plate 21, and a zipper limiting plate 22 mounted on the pressure plate 21 and movable via a cylinder. One end of the connecting plate 20 is mounted on the moving mechanism 2, and the other end of the connecting plate 20 is connected to the pressure plate 21 via a cylinder. The lifting and lowering of the pressure plate 21 is achieved by the extension and retraction of the cylinder. A pressure plate 23 is provided at the bottom of the pressure plate 21, and a cylinder is provided on the pressure plate 21 connected to one end of the pressure plate 23. When the pressure plate mechanism 3 removes the material plate 7, the cylinder extends and retracts, pulling one end of the pressure plate 23 to move. The other end of the pressure plate 23 deforms and moves downward to press tightly against the fabric, clamping the fabric between the pressure plate 23 and the material plate 7. The zipper limiting plate 22 rises via a cylinder. After the zipper is inserted, the zipper limiting plate 22 descends, and the zipper is clamped between the pressure plate 21 and the zipper limiting plate 22.

[0033] The pressure plate 21 has a lower seam groove 24, and the zipper limiting plate 22 has an upper seam groove 25 corresponding to the lower seam groove 24. A toothed rack 26 is placed within the upper seam groove 25 on the zipper limiting plate 22, tightly pressing the zipper to prevent it from shifting during operation. The sewing machine 6 passes through the upper seam groove 25 and the lower seam groove 24, and sews the zipper and fabric along the contours of the upper and lower seam grooves 25 and 24.

[0034] The lower seam groove 24 is equipped with a movable shaping knife 27. The sewing machine sews the zipper and fabric along the contour of the shaping knife 27. After the sewing is completed, the shaping knife opens, and the pressure plate mechanism 3 is lifted so that the zipper can pass through the lower seam groove 24, leaving the sewn fabric and zipper on the table of the main frame 1, which can be manually removed.

[0035] The folding knife mechanism 4 includes a folding knife mounting base 28, a drive motor 29, a movable front folding knife 30, a rear folding knife 31, and side folding knives 32 on both sides. The drive motor 29 drives the folding knife mounting base 28 to rise and fall through the meshing of gears and racks. The front folding knife 30, the rear folding knife 31, and the side folding knives 32 are mounted on the folding knife mounting base 28. The front folding knife 30, the rear folding knife 31, and the side folding knives 32 are pushed by a cylinder to fold and flip the cut fabric to form a bag lip.

[0036] The cutting mechanism 8 uses a laser tube to cut the fabric into two Y-shaped sections connected at the ends. The front folding blade 30 is symmetrical to the rear folding blade 31, and the two move in opposite directions to open or close to the sides, which is used to fold the straight cut to the sides. The two side folding blades 32 are symmetrically arranged to fold the triangular cuts on both sides, and to stack the two sides of the fabric into a double layer, making the sewn more secure and the pocket less likely to tear off.

[0037] The circulating feeder 5 includes a transverse cylinder and guide rail, a longitudinal cylinder and guide rail, a support base 33, and a clamp 34 mounted on the support base 33 for gripping the material plate 7. The transverse cylinder drives the support base 33 to move left and right, and the longitudinal cylinder drives the support base 33 to move back and forth. After the material plate 7 on the pressure plate mechanism 3 is sewn, the circulating feeder 5 moves to the rear of the pressure plate mechanism 3 and removes the material plate 7 through the clamp 34. After the pressure plate mechanism 3 removes the material plate 7 that has been unloaded from the main frame 1, the circulating feeder 5 sends the material plate 7 back to the worktable of the main frame 1. When the pressure plate mechanism 3 descends to remove the material plate 7, there are conical blocks on both sides of the end of the material plate 7. The cylinder extends and retracts to push the connecting posts on both sides of the pressure plate mechanism 3 into the conical blocks to form a fixed connection between the material plate 7 and the pressure plate mechanism 3.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
