Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to an automatic pocket machine including a folding knife mechanism. Background Technology

[0002] In garment manufacturing, pocket opening machines are essential auxiliary processing machinery, mainly used to create pockets in specific locations on garments, allowing users to place small items such as mobile phones, wallets, and keys. The processing of the pocket opening involves cutting, folding, shaping, and sewing the pocket opening area. Cutting involves cutting the pocket opening into the predetermined shape, folding involves folding the cut pocket opening inward to form a folded edge, shaping involves placing the pocket lip on the folded edge, and finally, sewing.

[0003] Pocket machines require a folding blade to fold and cut the fabric to form the pocket lip during the folding process. The step of retracting the blade after folding is essential. However, existing pocket machine folding blades tend to pull out the folded fabric during the retraction process, resulting in a poor user experience. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides an automatic pocket maker including a folding knife mechanism. To solve the above-mentioned technical problems, this utility model provides the following technical solution.

[0005] An automatic pocketing machine including a folding knife mechanism includes a worktable and a support frame mounted on the worktable, and also includes a sewing machine mounted on the worktable, a laser cutting mechanism for cutting fabric, a moving mechanism, at least two reusable material plates, a fixing mechanism, a folding knife mechanism, and a reusable feeding mechanism. The moving mechanism is mounted on the support frame and can move forward, backward, left, and right. The fixing mechanism is vertically connected to the moving mechanism and is used to fix the fabric and zipper. The moving mechanism drives the fixing mechanism to move and remove the material board to the sewing machine for work. The circulating feeding mechanism is movably installed behind the fixed mechanism and is used to remove the material plate placed on the workbench or to remove the material plate that has completed its work on the fixed mechanism. The folding knife mechanism is mounted on the support frame in a height-adjustable and size-adjustable manner. It is used to fold the cut fabric to form a pocket. The end of the folding knife mechanism is provided with a pocket-folding part. The fixing mechanism is equipped with a movable fabric limiting mechanism. The fabric is clamped between the fabric limiting mechanism and the material plate. The fabric limiting mechanism has a notch at one end near the folding knife mechanism. The folding knife mechanism moves laterally and pushes the cut fabric into the fabric limiting mechanism through the folding part. The folding part and the notch fit together. After the folding knife mechanism completes the folding, it moves longitudinally to retract the knife.

[0006] Furthermore, the folding knife mechanism includes a first support mounted on a support frame, a slider that slides up and down at the front end of the first support, and a second support mounted on one end of the slider. The bottom of the second support is provided with a lead screw motor and movable first and second lower sliders. The first and second lower sliders are respectively provided with a first folding knife assembly and a second folding knife assembly. The first folding knife assembly is symmetrical to the second folding knife assembly and the two move in opposite directions. The lead screw motor drives the first and second lower sliders to simultaneously drive the first and second folding knife assemblies to move laterally to fold the bag. The folding part is located at the end of the first and second folding knife assemblies.

[0007] Furthermore, both the first folding knife assembly and the second folding knife assembly include a fixing plate mounted on the bottom of the first or second lower slider, a folding knife mounted on the fixing plate, and several folding knife extensions of different sizes. Mounting portions are provided between the two sides of the folding knife and the folding knife extensions. Folding knife extensions of any size can be detachably and replaceably mounted on both sides of the folding knife through the mounting portions.

[0008] Furthermore, the mounting part includes a mounting block protruding on one side of the folding knife extension and mounting grooves on both sides of the folding knife that adapt to the mounting blocks. The mounting blocks are embedded in the mounting grooves and fixed by screws.

[0009] Furthermore, the folding knife includes a first folding knife panel mounted on a fixed plate and a plurality of push rods evenly distributed on the first folding knife panel; the folding knife extension includes a second folding knife panel and a plurality of push rods evenly distributed on the second folding knife panel, with a cavity formed between every two adjacent push rods, the width of the cavity being greater than the width of the push rod.

[0010] Furthermore, the folding bag section includes a rod extending laterally to one side from the end of the push rod, and a guide section is provided at the port of the folding bag section.

[0011] Furthermore, the fabric limiting mechanism includes pressure plates located at the front and rear ends and cylinders for pushing the pressure plates. When the folding knife mechanism folds the bag, the cylinders push out the pressure plates.

[0012] Furthermore, the notch portion includes notches evenly distributed at the end of the tablet pressing, the notches are intersecting with the folding bag portion and the size of the notch corresponds to the size of the folding bag portion. When folding the bag, the folding knife moves laterally, the two folding bag portions are embedded in the notches on their respective sides, and the folding bag portions are flush with the notch portion. When the folding knife retracts, the folding bag portion rises and disengages from the notch portion.

[0013] Furthermore, the fixing mechanism is provided with a seam groove and a liftable pressure strip. The pressure strip is raised and lowered by a cylinder to clamp or loosen the zipper placed in the seam groove.

[0014] Furthermore, the end of the pressure strip is provided with a toothed strip, which is placed on the seam groove.

[0015] Compared with the prior art, the beneficial effects that this utility model can achieve are: The folding blade mechanism of this utility model has a folding bag section at its end. The folding blade section pushes the fabric to fold and form a bag lip. The fixing mechanism has a movable fabric limiting mechanism. The fabric is clamped between the fabric limiting mechanism and the material plate. The fabric limiting mechanism has a notch at one end near the folding blade mechanism. The folding blade mechanism moves laterally and pushes the cut fabric into the fabric limiting mechanism through the folding bag section, realizing the folding of the fabric to form a bag lip. The fabric limiting mechanism always presses down on the fabric. The folding bag section and the notch are interlocked. After the folding blade mechanism completes the folding bag, it rises upward and disengages from the notch to retract the blade. The design of the notch allows the folding blade mechanism to retract the blade directly without first moving laterally and then rising. This effectively avoids the folding blade mechanism pulling out the folded fabric during the retraction process, reduces the number of steps, and ensures a good user experience.

[0023] 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.

[0024] like Figure 1-6 As shown, an automatic pocket making machine including a folding knife mechanism includes a worktable 1 and a support frame 9 mounted on the worktable 1. It also includes a sewing machine 2, a laser cutting mechanism 3 for cutting fabric, a moving mechanism 4, at least two circulating material plates 8, a fixing mechanism 5, a folding knife mechanism 7, and a circulating feeding mechanism 6, all mounted on the worktable. The moving mechanism 4 is mounted on the support frame 9 and can move back and forth and left and right via a horizontal cylinder and a vertical cylinder and a guide rail. The fixing mechanism 5 is vertically and vertically connected to the moving mechanism 4 and is used to fix the fabric and zipper. The moving mechanism 4 drives the fixing mechanism 5 to move back and forth and left and right. The fixing mechanism 5 is raised and lowered by its own mounted cylinder. The fabric is placed onto the fixed mechanism 5 during operation. The fixed mechanism 5 then moves to one side to remove the material plate 8 containing the zipper. Finally, it moves to the bottom of the sewing machine 2 to sew the fabric and zipper together to form a pocket. The circulating feeding mechanism 6 is movably installed behind the fixed mechanism 5. It is used to remove the material plate 8 placed on the workbench 1 or to remove the material plate 8 located on the fixed mechanism 5 after it has been used. The two material plates 8 are used in a cycle. The folding knife mechanism 7 is mounted on the support frame 9 in a height-adjustable manner. After the fabric is cut, the folding knife mechanism 7 descends to fold the cut fabric to form a pocket. The end of the folding knife mechanism 7 is provided with a folding bag part 10. The folding knife part 10 pushes the fabric to fold and form a bag lip. The fixed mechanism 5 is equipped with a movable fabric limiting mechanism 11. The fabric is clamped between the fabric limiting mechanism 11 and the material plate 8. The fabric limiting mechanism 11 has a notch 12 at one end near the folding knife mechanism 7. The folding knife mechanism 7 moves laterally and pushes the cut fabric into the fabric limiting mechanism 11 through the folding bag part 10, realizing the folding of the fabric to form a bag lip. The fabric limiting mechanism 11 always presses down on the fabric. The folding bag part 10 and the notch 12 are interlocked. After the folding knife mechanism 7 completes the folding bag, it rises upward and disengages from the notch 12 to achieve knife retraction. The design of the notch 12 eliminates the need for the folding knife mechanism 7 to move laterally before rising, effectively preventing the folding knife mechanism 7 from pulling out the folded fabric during the knife retraction process, ensuring a good user experience.

[0025] The folding knife mechanism 7 includes a first support 13 mounted on a support frame 9, a slider 14 sliding up and down at the front end of the first support 13, and a second support 15 mounted on one end of the slider 14. The bottom of the second support 15 is equipped with a screw motor 16 and movable first lower sliders 17 and 18. A first folding knife assembly 31 and a second folding knife assembly 32 are respectively mounted on the first lower slider 17 and 18. The first folding knife assembly 31 is symmetrical to the second folding knife assembly 32, and the two move in opposite directions. The screw motor 16 drives a double-threaded screw to move the first lower slider 17 and 18 in opposite directions simultaneously. The first folding knife assembly 31 and 32 open to the sides or move towards the center. The folding pocket section 10 is located at the end of the first folding knife assembly 31 and 32. Existing folding knives typically fold pockets by rotating the knife to fold the cut fabric. This design folds pockets by lateral movement, allowing for controllable movement distance and enabling the folding of smaller or larger pockets.

[0026] Both the first folding knife assembly 31 and the second folding knife assembly 32 include a fixing plate 20 installed at the bottom of the first lower slider 17 and the second lower slider 18, a folding knife 33 installed on the fixing plate 20, and several folding knife extensions 34 of different sizes. Mounting parts 19 are provided between the two sides of the folding knife 33 and the folding knife extensions 34. Folding knife extensions 34 of any size can be detachably and replaceably installed on both sides of the folding knife 33 through the mounting parts 19. Workers can select a suitable folding knife extension 34 to install on both sides of the folding knife 33 according to the required bag size. This allows the size of the folding knife 33 to be adjusted without replacing the entire folding knife mechanism 7, thus satisfying the compatibility of the equipment.

[0027] The mounting part 19 includes a mounting block 35 protruding on one side of the folding knife extension 34 and mounting grooves 36 on both sides of the folding knife 33 that adapt to the mounting block 35. The mounting block 35 is embedded in the mounting groove 36 and fixed by screws, making it convenient to install or remove the folding knife extension 34.

[0028] The folding blade 33 includes a first folding blade panel 37 mounted on the fixed plate 20 and a plurality of push rods 21 evenly distributed on the first folding blade panel 37; the folding blade extension 34 includes a second folding blade panel 38 and a plurality of push rods 21 evenly distributed on the second folding blade panel 38, and the number of push rods 21 on different sized folding blade extensions 34 is different. A cavity 22 is formed between every two adjacent push rods 21, and the width of the cavity 22 is greater than the width of the push rod 21, allowing the push rods 21 to pass through the cavity 22. When the first folding blade assembly 31 and the second folding blade assembly 32 move laterally, the push rods 21 on the first folding blade assembly 31 pass through the cavity 22 of the second folding blade assembly 32.

[0029] The folding bag section 10 includes a rod extending laterally to one side from the end of the push rod 21. The folding bag section 10 has a guide section 23 at its port. The guide section 23 is an inclined surface. During the process of pushing the fabric, the fabric can gradually fold along the inclined surface of the guide section 23, which provides assistance.

[0030] The fabric limiting mechanism 11 includes pressure plates 24 located at the front and rear ends and cylinders for pushing the pressure plates 24 to move. When the folding knife mechanism 7 folds the bag, the cylinder pushes out the pressure plates 24, and the folding knife mechanism 7 folds the cut fabric to the lower end of the pressure plates 24.

[0031] The notch portion 12 includes several notches evenly distributed at the end of the pressing sheet 24. The notches are intersected with the folding pocket portion 10 and the size of the notches corresponds to the size of the folding pocket portion 10. When folding the pocket, the folding knife 19 moves laterally, and the two folding pocket portions 10 are embedded in the notches on their respective sides. The folding pocket portion 10 is flush with the notch portion. When the folding knife retracts, it drives the folding pocket portion 10 to rise and disengage longitudinally from the notch portion 12. Therefore, the fabric that has been folded will not be pulled out during the retraction process.

[0032] The fixing mechanism 5 includes a longitudinal connecting plate 25 and a transverse connecting plate 26, which are connected by a cylinder. The longitudinal connecting plate 25 is mounted on the moving mechanism 4. The moving mechanism 4 drives the fixing mechanism 5 to move back and forth and left and right. The extension and retraction of the cylinder drives the transverse connecting plate 26 to move up and down. The transverse connecting plate 26 is provided with a seam groove 27. The zipper is placed in the seam groove 27. The fixing mechanism 5 drives the fabric of the folded bag to the sewing machine 2 to sew the pocket and zipper. The sewing machine sews along the contour of the seam groove 27.

[0033] The fixing mechanism is equipped with a height-adjustable pressure bar 28. A cylinder drives the pressure bar 28 to rise and fall, clamping or releasing the zipper placed in the seam groove 27. Before the zipper is placed, the cylinder raises the pressure bar 28; after the zipper is placed, the cylinder lowers the pressure bar 28 to press down on the zipper, thus limiting its movement. A toothed rack 29 is located at the end of the pressure bar 28 and rests on the seam groove 27. The toothed rack 29 further enhances the limiting effect on the zipper, preventing misalignment due to vibration during operation and increasing the product's pass rate.

[0034] The circulating feeding mechanism 6 includes a transverse cylinder and guide rail, a longitudinal cylinder and guide rail, and a clamp 30 for clamping the material plate 8. The clamp 30 is driven by two cylinders in different directions to move back and forth and left and right to clamp the material plate 8. After the sewing is completed on the fixed mechanism 5, the circulating feeding mechanism 6 moves behind the fixed mechanism 5 and then moves forward to clamp the material plate 8. The fixed mechanism 5 moves to remove another material plate 8 that has been unloaded from the worktable 1. The circulating feeding mechanism 6 moves again to put the removed material plate 8 back onto the worktable 1.

[0035] The steps of the automatic bag opening machine in this solution are as follows: The first step is to place the fabric on the material plate 8, and the fixing mechanism 5 removes the material plate 8 containing the fabric. The second step is to open the bag. The moving mechanism 4 moves the fixing mechanism 5, which contains the fabric, to below the laser cutting mechanism 3. The laser cutting mechanism 3 cuts the fabric to form a pocket opening. The third step is to fold the bag. The folding knife mechanism 7 descends and folds the cut of the fabric to form the bag lip. After the bag is folded, the folding knife head 7 retracts. Fourth step, insert the zipper. The pressure strip 28 rises and the zipper is inserted into the seam groove 27. The pressure strip 28 then descends to hold the zipper in place. The fifth step is to sew the zipper and the fabric together. The fixing mechanism 5 moves to the bottom of the sewing machine 2 to sew the fabric and the zipper together. After the sewing is completed, it rises up, the fabric is manually removed, and the circulating feeding mechanism 6 moves to the back of the fixing mechanism 5 to remove the material plate 8 and send it back to the worktable 1.

[0036] 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.
