Description

Technical Field

[0001] This application relates to the field of textile technology, and in particular to a collar pressing mold and a collar sewing device. Background Technology

[0002] A collar pressing die is a mold used to pre-press and fix collar pieces before they are sewn together. Before sewing the collar, the shorter and longer collar pieces need to be aligned and overlapped along their straight edges and sides, and a protrusion is formed on the longer piece to ensure the curvature of the finished collar.

[0003] Existing collar pressing molds usually require separate clamping parts to be set on the side of the collar piece to press it. Since the protrusions of some pieces are relatively close to the side of the piece, the space available for clamping on the side is small, which leads to poor clamping effect or inability to effectively fix the piece.

[0019] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] The inventors discovered through analysis of existing technology that the aforementioned technical problems can be solved by improving the molding structure. This application uses a U-shaped clamping member to press and fix the outer side of the protrusion of the cut piece, which not only ensures that the outer side of the protrusion and the cut piece as a whole can be effectively fixed, but also ensures the alignment effect of the side when the side of the cut piece is small, without the need to set a separate clamping member for the side of the cut piece.

[0021] Reference Figure 1-5This application illustrates a collar pressing mold 10 according to an embodiment of the present application. The collar pressing mold 10 is used to fix the protrusion of the collar piece 20. The collar pressing mold 10 includes: a central pressing member 11, a first U-shaped pressing member 12, a second U-shaped pressing member 14, a first protrusion pressing member 13, and a second protrusion pressing member 15. The first U-shaped clamping member 12 and the second U-shaped clamping member 14 are respectively disposed on different sides of the middle clamping member 11; the first convex clamping member 13 is disposed on the inner side of the first U-shaped clamping member 12, and the second convex clamping member 15 is disposed on the inner side of the second U-shaped clamping member 14; When the cut piece 20 is pressed down, the first U-shaped clamping member 12 presses against the outside of the first protrusion 21 of the cut piece 20 and fixes it, the second U-shaped clamping member 14 presses against the outside of the second protrusion 22 of the cut piece 20 and fixes it, the first protrusion clamping member 13 presses against the first protrusion 21, and the second protrusion clamping member 15 presses against the second protrusion 22.

[0022] In the embodiments of this application, addressing the problem that existing collar pressing molds 10 have poor pressing effect or cannot effectively fix the cut piece 20, this application provides a solution by improving the pressing member structure to a U-shaped pressing member, specifically: a collar pressing mold 10, the collar pressing mold 10 being used to fix the protrusion of the collar cut piece 20; the collar pressing mold 10 includes: a central pressing member 11, a first U-shaped pressing member 12, a second U-shaped pressing member 14, a first protruding pressing member 13, and a second protruding pressing member 15; the first U-shaped pressing member 12 and the second U-shaped pressing member 14 are respectively disposed on the... Different sides of the central clamping member 11; the first convex clamping member 13 is disposed inside the first U-shaped clamping member 12, and the second convex clamping member 15 is disposed inside the second U-shaped clamping member 14; when the cut piece 20 is pressed down, the first U-shaped clamping member 12 presses against the outside of the first protrusion 21 of the cut piece 20 and fixes it, the second U-shaped clamping member 14 presses against the outside of the second protrusion 22 of the cut piece 20 and fixes it, the first convex clamping member 13 presses against the first protrusion 21, and the second convex clamping member 15 presses against the second protrusion 22. This application uses U-shaped clamping members to press and fix the outside of the protrusion of the cut piece 20, which not only ensures that the outside of the protrusion and the cut piece 20 as a whole can be effectively fixed, but also ensures the alignment effect of the side when the side of the cut piece 20 is small, without the need to set separate clamping members for the side of the cut piece 20.

[0023] The following will describe a collar molding 10 in an embodiment of this application.

[0024] It should be noted that by pressing the U-shaped clamping member against the outer side of the corresponding protrusion, the pressing structure on the outer side of the protrusion can be maintained when the cut piece 20 is moved by the pressing mold. This ensures that the cut piece 20 can form a flexible collar structure after sewing, and also prevents the longer cut piece 20 from slipping and causing the edges of the cut piece 20 to become misaligned.

[0025] As an example, since the structures of the first protrusion 21 and the second protrusion 22 are generally symmetrical, the first U-shaped clamping member 12 and the second U-shaped clamping member 14 can adopt symmetrical structures, and the first protruding clamping member 13 and the second protruding clamping member 15 can adopt symmetrical structures. It should be understood that other structures in the embodiments of this application can also refer to the description of the corresponding symmetrical structures.

[0026] Reference Figure 2 and Figure 4 In one embodiment of this application, the first U-shaped clamping member 12 includes a first pressing part 121, a first extension part 122, and a second pressing part 123; The first pressing part 121 is disposed on one side of the first protruding pressing member 13, and the second pressing part 123 is disposed on the other side of the first protruding pressing member 13. The first extension part 122 is connected to the first pressing part 121 and the second pressing part 123 through the first protruding pressing member 13. When the cut piece 20 is pressed down, the first pressing part 121 and the second pressing part 123 are pressed onto different sides of the first protrusion 21 respectively.

[0027] It should be noted that the first pressing part 121, the first extension part 122 and the second pressing part 123 are equivalent to a U-shaped structure surrounding the first protruding pressing member 13, so that when the first U-shaped pressing member 12 performs a pressing action, the outer side of the first protrusion 21 can be fixed first, and then the first protruding part 21 is pressed down by the first protruding pressing member 13 to achieve the overall pressing of the cut piece 20.

[0028] In one specific embodiment of this application, the second U-shaped clamping member 14 includes a third pressing part 141, a second extension part 142, and a fourth pressing part 143; The third pressing part 141 is disposed on one side of the second protruding pressing member 15, and the fourth pressing part 143 is disposed on the other side of the second protruding pressing member 15. The second extension part 142 is connected to the third pressing part 141 and the fourth pressing part 143 through the second protruding pressing member 15. When the cut piece 20 is pressed down, the third pressing part 141 and the fourth pressing part 143 are pressed onto different sides of the second protrusion 22 respectively.

[0029] In one embodiment of this application, the first extension 122 is movably connected to the first protrusion pressing member 13; the second pressing part 123 is movably connected to the first extension 122.

[0030] It should be noted that the relative position between the first extension 122 and the first protruding pressing member 13 is adjustable to accommodate different lengths of cut pieces 20; the angle between the second pressing part 123 and the first extension 122 is adjustable to accommodate different edge shapes of cut pieces 20.

[0031] As an example, the first extension 122 can be movably connected to the first protrusion clamping member 13 via two guide grooves, and the second pressing part 123 can be movably connected to the first extension 122 via a fixing hole and an arc-shaped groove.

[0032] In one specific embodiment of this application, the second extension 142 is movably connected to the second protrusion pressing member 15; the fourth pressing part 143 is movably connected to the second extension 142.

[0033] In one embodiment of this application, the first U-shaped clamping member 12 includes a first corner clamping member 124; the first corner clamping member 124 is movably disposed on the second pressing part 123.

[0034] It should be noted that the first corner presser 124 can be used to press the corners of the cut piece 20 to ensure alignment.

[0035] As an example, the first corner clamp 124 can be movably connected to the second pressing part 123 through a fixing hole and an arc groove.

[0036] In one specific embodiment of this application, the second U-shaped clamping member 14 includes a second corner clamping member 144; the second corner clamping member 144 is movably disposed on the fourth pressing part 143.

[0037] Reference Figure 2-4 In one embodiment of this application, a first wiring groove 1231 is provided between the second pressing part 123 and the first protruding pressing member 13.

[0038] It should be noted that since the second pressing part 123 can directly press the side of the cut piece 20, the first stitching groove 1231 can be directly sewn to ensure stitching quality, and there is no need to reserve stitching space on the side of the cut piece 20 outside the first U-shaped pressing part 12.

[0039] In one specific embodiment of this application, a second wiring groove 1431 is provided between the fourth pressing part 143 and the second protruding pressing member 15.

[0040] Reference Figure 5 In one embodiment of this application, it further includes: a first translation motor 161, a first cylinder seat 162, a first lifting cylinder 163 and a second lifting cylinder 164; The output shaft of the first translation motor 161 is movably connected to the first cylinder seat 162 via a lead screw mechanism; The first lifting cylinder 163 and the second lifting cylinder 164 are disposed on the first cylinder seat 162; The output end of the first lifting cylinder 163 is connected to the first U-shaped clamping member 12; the output end of the second lifting cylinder 164 is connected to the first protruding clamping member 13.

[0041] It should be noted that by simultaneously fixing the first lifting cylinder 163 and the second lifting cylinder 164 to the first cylinder seat 162, when the first translation motor 161 drives the first cylinder seat 162, the first lifting cylinder 163 and the second lifting cylinder 164 can move synchronously to ensure that the relative positions of the first U-shaped clamping member 12 and the first protruding clamping member 13 remain unchanged in the same direction.

[0042] In one embodiment of this application, it further includes: a second translation motor 171, a second cylinder base 172, a third lifting cylinder 173 and a fourth lifting cylinder 174; The output shaft of the second translation motor 171 is movably connected to the second cylinder seat 172 via a lead screw mechanism; The third lifting cylinder 173 and the fourth lifting cylinder 174 are disposed on the second cylinder seat 172; The output end of the third lifting cylinder 173 is connected to the second U-shaped clamping member 14; the output end of the fourth lifting cylinder 174 is connected to the second protruding clamping member 15.

[0043] It should be noted that by simultaneously fixing the third lifting cylinder 173 and the fourth lifting cylinder 174 to the second cylinder seat 172, when the second translation motor 171 drives the second cylinder seat 172, the third lifting cylinder 173 and the fourth lifting cylinder 174 can move synchronously, ensuring that the relative positions of the second U-shaped clamping member 14 and the second protruding clamping member 15 remain unchanged. Each clamping member can perform a pressing action through its corresponding lifting cylinder to achieve the pressing of the cut piece 20.

[0044] Since the first translation motor 161 and the second translation motor 171 are independent of each other, the first cylinder seat 162 and the second cylinder seat 172 can have different strokes, which is suitable for pressing some asymmetrical structure pieces 20.

[0045] In one embodiment of this application, it further includes: a base 18; the first translation motor 161 and the second translation motor 171 are disposed on the base 18; The base 18 is provided with a third cylinder seat 181 and a fifth lifting cylinder 182; the fifth lifting cylinder 182 is disposed on the third cylinder seat 181; the output end of the fifth lifting cylinder 182 is connected to the central clamping member 11.

[0046] It should be noted that the base 18 ensures that the components of the molding die can be moved as a whole, facilitating modular installation in sewing equipment.

[0047] Reference Figure 6-7 This paper illustrates a collar sewing device according to an embodiment of the present application, including: a support platform 30, a sewing machine 40, a pressure mold displacement mechanism 50, and a collar pressure mold 10 as described in any embodiment of the present application; The collar pressing mold 10 is disposed on the pressing mold displacement mechanism 50; the pressing mold displacement mechanism 50 and the sewing machine 40 support platform 30; When the pressing of the cut piece 20 is completed, the pressing mold displacement mechanism 50 drives the collar pressing mold 10 to move the cut piece 20 to the sewing machine 40 along the support platform 30 for stitching processing.

[0048] It should be noted that the die displacement mechanism 50 can be fixedly connected to the collar die 10 via the base 18. The die displacement mechanism 50 can translate or rotate the collar die 10 according to a preset program, so that the sewing machine 40 can accurately stitch the cut piece 20.

[0049] In one embodiment of this application, it further includes: a protrusion support mechanism 60; the protrusion support mechanism 60 is disposed on the support platform 30 and at a position corresponding to the collar pressing mold 10; Before pressing down the cut piece 20, the protrusion support mechanism 60 supports the cut piece 20 to form the first protrusion 21 and the second protrusion 22; When the first protrusion 21 and the second protrusion 22 are fixed, the protrusion support mechanism 60 disengages from the cut piece 20.

[0050] It should be noted that the protrusion support mechanism 60 can extend and retract. When the shorter piece 20 is placed, the protrusion support mechanism 60 extends to support the longer piece 20 to form the first protrusion 21 and the second protrusion 22; when the piece 20 is pressed down, the protrusion support mechanism 60 extends.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.
