[0001] This invention relates to the field of patching machine technology, specifically to a patching machine folding mechanism for rounded corner shirt pockets. Background Technology

[0002] The patch pocket machine can be used for sewing pockets on clothing such as jeans, work clothes, and shirts. It can complete flat stitching and buttonhole stitching in one go, and is suitable for sewing back pockets of various jeans, work clothes pockets, and shirt pockets.

[0003] In pocket patching machines, a folding mechanism is typically used to fold the edges of the pocket fabric to be sewn, facilitating subsequent processes. Application publication number CN110699864A discloses a high-precision automatic wrinkle-free pocket patching machine, specifically comprising a worktable, a pocket piece auxiliary mechanism, a flipping mechanism, a feeding unit, a sewing machine head, a display screen, and a frame.

The feeding unit is mounted on the upper surface of the worktable via welded components, and the feeding unit includes an X-axis moving component, a Y-axis moving component, and a pressing component. The sewing machine head is located on one side of the pressing component on the upper surface of the worktable. The flipping mechanism includes a flipping frame, a drive arm, a bearing seat, a flipping cylinder, a falling cylinder, a square bearing seat, a flipping shaft, and a bag folding assembly; the bag folding assembly includes a pressing frame, a bag folding cylinder, a bag folding plate, an electromagnet, and a bag pressing plate. The pressing frame has a bag pressing plate in the middle, and the bag pressing plate has an electromagnet in the middle. The pressing frame has multiple bag folding cylinders, and the driving rods of the multiple bag folding cylinders are equipped with bag folding plates, which are located between the pressing frame and the bag pressing plate.

[0004] Many shirt pockets feature rounded bottom corners on both sides for a more aesthetically pleasing appearance. However, the folding mechanism in the aforementioned high-precision automatic wrinkle-free patching machine cannot fold these corners into a rounded shape during the folding process, thus failing to meet the requirements for producing rounded corner shirt pockets. Therefore, improvements to the existing technology are necessary. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this invention is to provide a folding mechanism for a patch pocket machine for rounded corner shirt pockets. Through improvements, it is made to facilitate folding of the corresponding positions of the two sides of the pocket fabric, the bottom of the pocket, and the two lower pocket corners, and the two lower pocket corners are both arc-shaped after folding, so as to meet the production requirements of rounded corner shirt pockets.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] A folding mechanism for a patch pocket applicator for rounded corner shirt pockets includes a positioning block and a pressing assembly, a folding assembly, and a flipping and lifting assembly respectively connected to the positioning block. The pressing assembly includes a pressing plate connected to the positioning block. The folding assembly includes a U-shaped plate matched to the outside of the pressing plate and connected to the positioning block at both ends, and two bag edge folding pieces, a bag bottom folding piece, two lower bag corner folding assemblies, and several moving cylinders evenly distributed in a U-shape on the U-shaped plate. Each lower bag corner folding assembly includes an upper arc-shaped folding piece and a lower arc-shaped folding piece with concave arc-shaped inner ends. The upper arc-shaped folding piece is located above the bag edge folding piece and the bag bottom folding piece, and the lower arc-shaped folding piece... The bag flap is located below the bag edge fold and the bag bottom fold; after folding, the inner end of the lower arc-shaped fold is closer to the pressing plate than the inner end of the upper arc-shaped fold; each of the bag edge fold, bag bottom fold, upper arc-shaped fold, and lower arc-shaped fold is connected to a moving cylinder to achieve inward and outward movement, thereby facilitating the folding of the corresponding positions of the two sides of the bag edge, the bag bottom, and the two lower bag corners of the pocket fabric. The upper arc-shaped fold and the lower arc-shaped fold can be used to fold the two lower bag corners into an arc shape by cooperation; the flipping and lifting assembly can be used to drive the positioning block to flip up and down and lift up and down, synchronously driving the pressing assembly and the folding assembly to flip up and down and lift up and down.

[0008] It also includes the following technical solutions:

[0009] Furthermore, the pressing assembly also includes a mounting plate detachably mounted on the positioning block; the pressing plate is adjustable up and down and mounted on the mounting plate. This configuration allows for easy assembly and disassembly of the mounting plate, enabling the pressing plate to be used with pocket fabrics of different sizes.

[0010] Furthermore, the pressing assembly also includes three adjusting bolts; the three adjusting bolts are threadedly connected to the mounting plate in a triangular arrangement, and the lower end of the shank of each adjusting bolt protrudes from the mounting plate and is threadedly connected to the pressing plate. This arrangement facilitates the adjustment of the position of the mounting plate.

[0011] Furthermore, an electromagnet is also provided at the middle position of the bag-pressing plate.

[0012] Furthermore, the folding assembly also includes two upper pocket corner folding pieces distributed at both ends of the U-shaped plate, and each upper pocket corner folding piece is drivenly connected to a moving cylinder to realize the folding edge of the upper pocket corner folding piece. The folding ends of the two upper pocket corner folding pieces can be used to reverse the upper pocket corner of the pocket edge after the first folding of the pocket fabric.

[0013] Furthermore, each of the upper pocket corner folding flaps is connected to the corresponding movable cylinder via a linkage assembly; the linkage assembly includes a V-shaped rod and a connecting rod; the middle part of the V-shaped rod is movably sleeved on a positioning post, and one end of the V-shaped rod is connected to the connecting end of the upper pocket corner folding flap; the two ends of the connecting rod are respectively hinged to the other end of the V-shaped rod and the output end of the movable cylinder. This arrangement allows the movable cylinder to easily drive the upper pocket corner folding flaps to rotate using the V-shaped rod and the connecting rod.

[0014] Furthermore, each of the movable cylinders connected to the edge fold, bottom fold, upper arc fold, and lower arc fold can be adjusted inwards and outwards on the U-shaped plate, and the adjustment direction of each movable cylinder is the same as the movement direction of its corresponding edge fold, bottom fold, upper arc fold, and lower arc fold; each of the movable cylinders connected to the upper corner fold can be adjusted left and right on the U-shaped plate. This configuration facilitates the adjustment of the inward and outward movement of each fold, making it suitable for folding pocket fabrics of different sizes, thus enhancing its practicality.

[0015] Furthermore, the U-shaped plate is provided with several strip-shaped adjustment holes, and a tightening bolt is inserted into each strip-shaped adjustment hole; each of the moving cylinders is equipped with an adjustment plate, and each adjustment plate is threadedly connected to two corresponding tightening bolts; the extension direction of each strip-shaped adjustment hole is the same as the adjustment direction of its corresponding moving cylinder. The above configuration facilitates the position adjustment of each folded bag flap.

[0016] Furthermore, the tilting and lifting assembly includes a tilting cylinder, a lifting cylinder, and a tilting base; the lower rear end of the tilting base is hinged to a positioned hinge shaft; the cylinder body of the tilting cylinder is hinged to the hinge base, and the output shaft of the tilting cylinder is hinged to the upper rear end of the tilting base; the lifting cylinder is mounted on the front side of the tilting base, and the output shaft of the lifting cylinder is connected downward to the positioning block. This configuration facilitates the tilting and lifting of the positioning block, the pressing assembly, and the folding assembly.

[0017] Furthermore, the two ends of the U-shaped plate are connected to the positioning block by two positioning bolts, which facilitates the assembly and disassembly of the positioning block.

[0018] The beneficial effects of this invention are as follows:

[0019] (i) This invention can conveniently use a movable cylinder to drive the edge folding piece, bottom folding piece, upper arc folding piece, and lower arc folding piece, thereby realizing the folding of the edge, bottom, and two lower pocket corners on both sides of the pocket fabric of the shirt pocket. Moreover, after the upper and lower arc folding pieces are folded in sequence, the two lower pocket corners will form arc-shaped lower pocket corners, which is aesthetically pleasing. Since the pocket fabric of the shirt is relatively thin, the setting of the upper and lower arc folding pieces can ensure the formation of arc-shaped pocket corners to meet the production requirements of rounded corner shirt pockets. The flipping and lifting component can be used to conveniently drive the pressing component and the folding component to flip up and down and lift up and down.

[0020] (ii) The present invention can adjust the height of the pressure plate and correct the balance by using three adjusting bolts, so as to ensure that the pressure plate can match and fit the pocket fabric.

[0021] (iii) Each of the pockets in this invention can be adjusted to move inward and outward. By adjusting the pocket pieces inward and outward, each pocket piece can be used to fold the edges of pocket fabrics of different sizes, making it highly practical. Attached Figure Description

[0036] The specific implementation methods according to this disclosure are described below with reference to the accompanying drawings.

[0037] like Figures 1-7As shown, a folding mechanism for a patch pocket of a rounded shirt pocket includes a positioning block 1 and a pressing assembly 2, a folding assembly 3, and a flipping and lifting assembly 4, all connected to the positioning block 1. The pressing assembly 2 includes a pressing plate 21 connected to the positioning block 1 and matching the shape of the pocket. The folding assembly 3 includes a U-shaped plate 31 matched to the outside of the pressing plate 21 and connected to the positioning block 1 at both ends, and two pocket edge folding pieces 32, a pocket bottom folding piece 33, two lower pocket corner folding assemblies, and several moving cylinders 36 evenly distributed on the U-shaped plate 31. Each lower pocket corner folding assembly includes an upper arc-shaped folding piece 34 and a lower arc-shaped folding piece 35 with concave arc-shaped inner ends. 34 is located above the bag edge folding piece 32 and the bag bottom folding piece 33, and the lower arc-shaped folding piece 35 is located below the bag edge folding piece 32 and the bag bottom folding piece 33; after folding, the inner end of the lower arc-shaped folding piece 35 is closer to the pressing plate 21 than the inner end of the upper arc-shaped folding piece 34; each bag edge folding piece 32, bag bottom folding piece 33, upper arc-shaped folding piece 34 and lower arc-shaped folding piece 35 is connected to a moving cylinder 36 to achieve the effect of inward and outward movement, so as to facilitate the folding of the corresponding positions of the two sides of the bag edge, the bag bottom and the two lower bag corners of the pocket fabric; the flipping and lifting assembly 4 can be used to drive the positioning block 1 to flip up and down and lift up and down, and simultaneously drive the pressing assembly 2 and the folding assembly 3 to flip up and down and lift up and down. The above configuration allows for convenient use of the movable cylinder 36 to drive the edge folding piece 32, bottom folding piece 33, upper arc-shaped folding piece 34, and lower arc-shaped folding piece 35, thereby enabling the folding of the pocket fabric's edge, bottom, and two lower pocket corners on both sides of the bottom. Furthermore, the two lower pocket corners, after being folded sequentially by the upper arc-shaped folding piece 34 and the lower arc-shaped folding piece 35, will form arc-shaped lower pocket corners, resulting in a high aesthetic appeal. Since the shirt pocket fabric is relatively thin, the upper arc-shaped folding piece 34 and the lower arc-shaped folding piece 35 ensure the formation of the arc-shaped pocket corners, meeting the requirements for making rounded shirt pockets. The flipping and lifting assembly 4 facilitates the driving of the pressing assembly 2 and the folding assembly 3 for flipping and lifting.

[0038] like Figure 6 As shown, specifically, in order to prevent the upper arc-shaped folding piece 34 from not moving properly and to ensure the folding effect, a relief groove 9 is provided on the top surface of one end of each bag edge folding piece 32 and the top surfaces of both ends of the bag bottom folding piece 33. The two sides of each upper arc-shaped folding piece 34 are correspondingly inserted into the two relief grooves 9, so that the movement of the upper arc-shaped folding piece 34 is smoother, and the upper arc-shaped folding piece 34 can stably perform the initial folding of the lower bag corner, and then the lower arc-shaped folding piece 35 is used for the secondary folding.

[0039] like Figures 1-5As shown, the pressing assembly 2 also includes a mounting plate 22 detachably mounted on the positioning block 1, and a pressing plate 21 is vertically adjustable and mounted on the mounting plate 22. Therefore, the pressing plate 21 is connected to the positioning block 1 via the mounting plate 22. Furthermore, since the mounting plate 22 is detachable, the pressing plate 21 can be replaced simultaneously with pressing plates of different sizes, allowing it to be used with pocket fabrics of different sizes. Additionally, because shirt pocket fabric is relatively thin, by making the pressing plate 21 vertically adjustable, it is easier to adjust its position according to the thickness of the shirt pocket fabric, preventing the pressing plate 21 from not fitting snugly against the pocket fabric after lowering.

[0040] like Figures 1-5 As shown, the pressing assembly 2 also includes three adjusting bolts 23. These three adjusting bolts 23 are threadedly connected to the mounting plate 22 in a triangular arrangement, with the lower end of the shank of each adjusting bolt 23 protruding from the mounting plate 22 and threadedly connected to the pressing plate 21. Preferably, one adjusting bolt 23 is located at the front, while the other two adjusting bolts 23 are distributed horizontally at the rear. With these three adjusting bolts 23, the height of the pressing plate 21 can be adjusted and its balance corrected by turning them up and down, thus facilitating the adjustment of the pressing plate 21. In use, turning one adjusting bolt 23 up or down will move the corresponding position of the pressing plate 21 up or down. Therefore, adjusting the height of the pressing plate 21 and correcting its balance can be achieved simply by using the three adjusting bolts 23, ensuring that the pressing plate 21 fits snugly against the pocket fabric.

[0041] like Figure 4 As shown, an electromagnet 24 is also provided in the middle of the bag pressing plate 21. When the electromagnet 24 is energized, it can magnetically attract the bag fixing plate (not shown) on the bag sheet auxiliary mechanism (not shown in the figure), so that the bag pressing plate 21 can be tightly attached to the bag fixing plate, thereby fixing the pocket fabric on the bag fixing plate and preventing it from loosening. Of course, when the electromagnet 24 is de-energized, it will lose its magnetic force, so that the bag fixing plate can be released.

[0042] like Figures 1-7As shown, the folding assembly 3 also includes two upper pocket corner folding pieces 37 distributed at both ends of the U-shaped plate 31. Each upper pocket corner folding piece 37 is connected to a moving cylinder 36 to achieve the folding and turning of the upper pocket corner folding piece 37. The folded ends of the two upper pocket corner folding pieces 37 can be used to reverse the folding of the upper pocket corners of the pocket edge after the first folding of the pocket fabric. Specifically, the folded ends of the upper pocket corner folding pieces 37 are located above the folded ends of the pocket edge folding pieces 32. By setting two upper pocket corner folding pieces 37, a second folding (i.e., reverse folding) can be performed on the two upper pocket corners, thereby preventing the upper pocket corners from being exposed outside the pocket and affecting the appearance.

[0043] Of course, the bag edge fold 32, bag bottom fold 33, upper arc fold 34, lower arc fold 35 and upper corner fold 37 are all located below the bag pressing plate 21.

[0044] like Figures 1-7 As shown, each upper pocket corner folding piece 37 is connected to a corresponding moving cylinder 36 via a linkage assembly. The linkage assembly includes a V-shaped rod 38 and a connecting rod 39. The middle part of the V-shaped rod 38 is movably sleeved on a positioning post 40, and one end of the V-shaped rod 38 is connected to the connecting end of the upper pocket corner folding piece 37. The two ends of the connecting rod 39 are respectively hinged to the other end of the V-shaped rod 38 and the output end of the moving cylinder 36. This arrangement allows the moving cylinder 46 to easily drive the upper pocket corner folding piece 37 to flip through the transmission of the V-shaped rod 38 and the connecting rod 39, thereby enabling reverse folding of the upper pocket corner. Moreover, this method is more stable and accurate than the traditional method of using a rotary cylinder to drive the upper pocket corner folding piece to rotate, meaning it can achieve better upper pocket corner folding.

[0045] like Figures 1-7 As shown, each movable cylinder 36 connected to each of the bag edge folding piece 32, bag bottom folding piece 33, upper arc-shaped folding piece 34, and lower arc-shaped folding piece 35 can be adjusted inwards and outwards on the U-shaped plate 31, and the adjustment direction of each movable cylinder 36 is the same as the movement direction of its corresponding bag edge folding piece 32, bag bottom folding piece 33, upper arc-shaped folding piece 34, and lower arc-shaped folding piece 35; each movable cylinder 36 connected to each upper bag corner folding piece 37 can be adjusted left and right on the U-shaped plate 31. This configuration facilitates the adjustment of the inward and outward movement of each folding piece, making it suitable for folding hems of different sized pocket fabrics, thus enhancing its practicality.

[0046] like Figures 1-7As shown, several strip-shaped adjustment holes 6 are provided on the U-shaped plate 31, and a tightening bolt 7 is inserted into each strip-shaped adjustment hole 6; an adjustment plate 5 is installed on each moving cylinder 36, and each adjustment plate 5 is threadedly connected to two corresponding tightening bolts 7; the extension direction of each strip-shaped adjustment hole 6 is the same as the adjustment direction of its corresponding moving cylinder 36. This arrangement facilitates the position adjustment of each folded bag flap. When the corresponding two tightening bolts 7 are loosened, the adjustment plate 5 can be moved along the extension direction of the strip-shaped adjustment hole 6, causing the tightening bolts 7 to move within the corresponding strip-shaped adjustment hole 6. Simultaneously, the corresponding moving cylinder 36 moves, and the corresponding folded bag flap moves accordingly, thus completing the position adjustment of the folded bag flap. After adjustment, tightening the tightening bolts 7 and the adjustment plate 5 fixes the adjustment plate 5, thus simultaneously fixing the corresponding moving cylinder 36 and the folded bag flap.

[0047] like Figure 4 As shown, preferably, for ease of setting, the two movable cylinders 36 connected to the upper arc-shaped folding piece 34 and the lower arc-shaped folding piece 35 are mounted on the same adjusting plate 5. That is, when adjusting the adjusting plate 5, the two movable cylinders 36 corresponding to the upper arc-shaped folding piece 34 and the lower arc-shaped folding piece 35 can be adjusted simultaneously, thereby achieving the effect of simultaneously adjusting the upper arc-shaped folding piece 34 and the lower arc-shaped folding piece 35.

[0048] like Figure 1-Figure 1 As shown, the tilting and lifting assembly 4 includes a tilting cylinder 41, a lifting cylinder 42, and a tilting seat 43. The lower rear end of the tilting seat 43 is hinged to a hinge shaft 44 that is positioned in place. The cylinder body of the tilting cylinder 41 is hinged to a hinge seat 45, and the output shaft of the tilting cylinder 41 is hinged to the upper rear end of the tilting seat 43. The lifting cylinder 42 is installed on the front side of the tilting seat 43, and the output shaft of the lifting cylinder 42 is connected downward to the positioning block 1. With the above arrangement, the tilting cylinder 41 can be used to drive the tilting seat 43 to tilt up and down. The tilting seat 43 can drive the positioning block 1, the pressing assembly 2, and the folding assembly 3 to tilt up and down synchronously through the lifting cylinder 42. In addition, during the extension and retraction of the output shaft of the lifting cylinder 42, the positioning block 1, the pressing assembly 2, and the folding assembly 3 can also be driven to lift up and down synchronously.

[0049] like Figures 1-2 As shown, in order to improve the stability between the positioning block 1 and the flipping seat 43 when they move, a guide rod can also be set between them.

[0050] like Figures 1-2 As shown, the two ends of the U-shaped plate 31 are connected to the positioning block 1 by two positioning bolts 8, which makes it easy to assemble and disassemble the positioning block 1.

[0051] Combination Figure 8The following describes the specific working principle of this invention to help you understand it:

[0052] First, install the hemming device for the shirt pocket patching machine in the corresponding position. Next, lay the shirt fabric on the workbench (not shown) and place the pocket fabric on the bag fixing plate (not shown) extending from the bag fixing plate of the bag fixing mechanism (not shown). Next, the flipping cylinder 41 drives the pressing assembly 2 and the hemming assembly 3 to flip downwards to a horizontal position. Next, the lifting cylinder 42 drives the pressing assembly 2 and the hemming assembly 3 to descend a certain distance until the pressing plate 21 covers the bag fixing plate and the electromagnet 24, after being energized, generates a suction force on the bag fixing plate, thereby fixing the pocket fabric. Next, driven by the corresponding moving cylinders 36, the bottom folding piece 33 and the two side folding pieces 32 move sequentially, folding the bottom and sides of the pocket fabric. Then, the two upper arc-shaped folding pieces 34 move inwards. The two lower pocket corners of the pocket fabric are folded until the two upper curved pocket flaps 34 move to the preset position and then stop. Next, the two lower curved pocket flaps 35 also move inwards to fold the two lower pocket corners of the pocket fabric a second time, making the two lower pocket corners perfectly shaped, i.e., the lower pocket corners are curved. When the two lower curved pocket flaps 35 move to the preset position and stop, the inner ends of the two lower curved pocket flaps 35 are closer to the pressure plate 21 than the inner ends of the two upper curved pocket flaps 34, ensuring the shaping of the two lower pocket corners. Next, the two upper pocket corner flaps 37 are flipped inwards by the linkage of the V-shaped rod 38 and the connecting rod 39, so that the two upper pocket corners, after the first fold of the two pocket edges, are folded in the opposite direction using the two upper pocket corner flaps 37, thus preventing the two upper pocket corners from protruding outside the pocket. After the folding is completed, the pocket fabric is now... Figure 8 The state shown is as follows; next, the pressing assembly 2, the folding assembly 3, and the bag piece fixing plate are lowered, and the folded pocket fabric is pressed onto the corresponding position of the material piece; next, each moving cylinder 36 is reset, and the lifting cylinder 42 and the flipping cylinder 41 are reset in sequence; finally, a material transfer assembly is used to move the folded pocket fabric and material piece to the sewing machine head for sewing.
