Description

Technical Field

[0001] This invention relates to the field of clothing technology, and in particular to a process for sewing the placket opening of a polo shirt. Background Technology

[0002] The placket refers to the opening, slit, or split in the center of the front of a shirt, trousers, or skirt. Usually, the placket is fitted with zippers, buttons, overlocks, snap fasteners, Velcro, or other accessories to help with opening and closing.

[0003] When sewing the placket, an opening needs to be made on the front piece first. Then, while smoothing the placket pieces in the same direction, the edge of the placket pieces needs to be aligned with the opening on the front piece before moving it to the sewing machine for sewing. During the movement, the placket pieces may become misaligned with the front piece, and an uneven opening on the front piece will also aggravate the misalignment, resulting in substandard placket sewing, increased production costs, and high technical requirements for the producer. Summary of the Invention

[0004] Therefore, in response to the above problems, this invention proposes a polo shirt placket opening sewing process that requires less operator skill.

[0005] To achieve the above objectives, the technical solution of the present invention is to provide a process for sewing the placket opening of a polo shirt. The polo shirt mold is placed on a template machine, the front piece pressing plate and the placket pressing plate on the polo shirt mold are lifted, the front piece of the polo shirt is then placed on the bottom plate of the polo shirt mold and aligned with the first opening on the bottom plate, and then the front piece pressing plate and the placket pressing plate of the polo shirt mold are placed on the bottom plate to press the front piece. Then, adjust the position of the polo shirt mold so that it aligns with the protrusions or grooves on the template machine. Start the template machine, which grabs the entire polo shirt mold and moves it. When it moves to the predetermined position, the laser on the template machine is activated. The laser passes through the third opening on the placket pressing plate and the second opening on the front piece pressing plate, and then burns through the front piece and passes through the first opening on the bottom plate. At this time, the polo shirt mold moves along the predetermined trajectory under the drive of the template machine, thereby cutting out the predetermined shape on the front piece in cooperation with the laser. Then the laser stops and the template machine resets. At this point, open the placket pressing plate, remove the part of the front piece that was laser-cut, and then place the placket piece on the upper side of the front piece pressing plate so that the placket piece is aligned with the edge line of the cut part of the front piece. At this point, fold the part of the placket that does not need to be sewn outwards, and then place the placket pressing plate on the front piece pressing plate to press the placket piece. Then adjust the position of the polo shirt mold so that it aligns with the protrusions or grooves on the template machine. Start the template machine, which will grab the entire polo shirt mold and move it. When it reaches the predetermined position, the sewing machine will start, and the polo shirt mold will continue to move along the predetermined trajectory. At this time, the sewing machine will pass through the first opening, the second opening, and the third opening to sew the placket and the front piece together. Then the sewing machine will stop, and the template machine will reset. At this point, open the placket clamping plate, fold the part of the placket piece located outside the second opening inward, then open the front piece clamping plate so that the placket piece can be passed through the second opening and the sewn front piece can be removed. The POLO shirt mold includes a base plate, a front panel pressing plate hinged to the base plate, and a placket pressing plate hinged to the pressing plate for pressing the placket piece. The base plate, the front panel pressing plate, and the placket pressing plate are also provided with a first opening, a second opening, and a third opening, respectively.

[0016] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0017] A process for sewing the placket opening of a polo shirt involves placing a polo shirt mold on a template machine, lifting the front piece 16 pressing plate 2 and the placket pressing plate 3 on the polo shirt mold, then placing the front piece 16 of the polo shirt on the bottom plate 1 of the polo shirt mold and aligning it with the first opening 4 on the bottom plate 1, and then covering the bottom plate 1 with the front piece 16 pressing plate 2 and the placket pressing plate 3 of the polo shirt mold, and pressing the front piece 16. Then, adjust the position of the POLO shirt mold so that it aligns with the protrusions or grooves on the template machine. Start the template machine, which grabs the entire POLO shirt mold and moves it. When it moves to the predetermined position, the laser on the template machine is activated. The laser passes through the third opening 6 on the placket pressing plate 3 and the second opening 5 on the front piece 16 pressing plate 2, and then burns through the front piece 16 and passes through the first opening 4 on the bottom plate 1. At this time, the POLO shirt mold moves along the predetermined trajectory under the drive of the template machine, thereby cutting out the predetermined shape on the front piece 16 in cooperation with the laser. Then the laser stops and the template machine resets. At this point, open the placket pressing plate 3, remove the portion of the front piece 16 that has been laser-cut, and then place the placket piece 17 on the upper side of the front piece 16 pressing plate 2, so that the placket piece 17 is aligned with the edge line of the portion of the front piece 16 that has been cut off. At this point, fold the part of the placket that does not need to be sewn outwards, and then place the placket pressing plate 3 on the front piece 16 pressing plate 2 to press the placket piece 17. Then adjust the position of the POLO shirt mold so that it aligns with the protrusions or grooves on the template machine. Start the template machine and move the entire POLO shirt mold. When it moves to the predetermined position, the sewing machine starts and the POLO shirt mold continues to move along the predetermined trajectory. At this time, the sewing machine passes through the first opening 4, the second opening 5 and the third opening 6 to sew the placket piece 17 and the front piece 16 together. Then the sewing machine stops and the template machine resets. At this point, open the placket clamping plate 3, fold the part of the placket piece 17 located outside the second opening 5 inward, and then open the front piece 16 clamping plate 2 so that the placket piece 17 can be passed through the second opening 5, and the sewn front piece 16 can be removed. like Figures 1-8As shown, the POLO shirt mold includes a base plate 1, a front piece 16 pressing plate 2 hinged to the base plate 1, and a placket pressing plate 3 hinged to the pressing plate for pressing the placket piece 17. The base plate 1, the front piece 16 pressing plate 2, and the placket pressing plate 3 are respectively provided with a first opening 4, a second opening 5, and a third opening 6. The base plate 1 and the placket pressing plate 3 are also provided with positioning devices that cooperate with the template machine.

[0018] To facilitate the positioning of the polo shirt mold, the positioning device includes: several moving holes 7 through the bottom plate 1 and the front piece 16 pressing plate 2 for the template machine to grasp and move; and several positioning grooves 8 through the bottom plate 1 and the front piece 16 pressing plate 2 for the user to align the template machine so that the mold can be grasped and moved.

[0019] To prevent the front piece 16 from collapsing during laser cutting or sewing and affecting the finished product, the base plate 1 is also equipped with a support device to support the front piece 16 and prevent it from collapsing directly downwards after being laser-cut, thus affecting the cutting and subsequent sewing results. The support device includes several stiff bristles 9 with a certain elasticity and hardness. One end of each stiff bristle 9 is attached to the side of the first opening 4 via an adhesive strip 10, and the other end is located on the upper side of the first opening 4 to support the front piece 16 and prevent it from interfering with the sewing machine's operation. When the front piece 16 is laser-cut, because the connection between the front piece 16 and the piece being cut is lost, the bristles will collapse towards the first opening 4. When the front piece 16 loses its support and collapses downwards, the stiff filament 9 will provide support to prevent the front piece 16 from collapsing downwards and affecting the straightness of the laser cut. During sewing, because the stiff filament 9 is small, the sewing machine needle can pass smoothly through the placket piece 17, the front piece 16, and the stiff filament 9 to sew the front piece 16 and the placket piece 17 together. Furthermore, because the stiff filament 9 has a certain degree of elasticity, when the sewing machine sews the placket piece 17, the front piece 16, and the stiff filament 9 together, the stiff filament 9 can also be easily pulled out of the sewing thread when the user removes the front piece 16. This achieves the function of one mold serving two purposes and greatly improves the production speed.

[0020] To facilitate the user's positioning of the front piece 16, the base plate 1 is provided with several size slots 11 that match the shape of the front piece 16, and the size slots 11 are provided with several positioning strips 12 to facilitate the user's alignment of the front piece 16.

[0021] To facilitate the user's positioning of the placket piece 17, the front panel 16 pressing plate 2 is also provided with a fixing device to further prevent the placket piece 17 from shifting during sewing. The fixing device includes: alignment strips 13 disposed on both sides of the second opening 5 to assist in the alignment of the placket piece 17, and an adhesive layer 14 disposed between the alignment strips 13 and the second opening 5 to prevent the placket pressing plate 3 from shifting when the placket piece 17 is not pressed after alignment. The adhesive layer 14 can be double-sided adhesive.

[0022] To enhance the ease of use of the mold, the base plate 1, the front piece 16 pressing plate 2, and the placket pressing plate 3 are also provided with through-holes that communicate with the first opening 4, the second opening 5, and the third opening 6 to avoid lasers and sewing machine needles.

[0023] Working principle: First, place the POLO shirt mold on the template machine. Then, adjust the position of the positioning strip 12 within the size slot 11 according to the size of the front piece 16. Next, align the front piece 16 with the positioning strip 12 and place it on the base plate 1. Then, cover the front piece 16 with the front piece 16 pressing plate 2 and the placket pressing plate 3. Next, align the positioning slot 8 on the POLO shirt mold with the template machine, start the template machine, and the moving mechanism on the template machine will pass through the moving hole 7, thus moving the moving hole 7 on the working plane of the template machine. Then, the laser will start, and the POLO shirt will... The placket mold moves along a predetermined trajectory under the drive of the template machine. When the front piece 16 is cut, part of the front piece 16 will collapse downwards due to loss of support. At this time, the stiff bristles 9 will support the unsupported front piece 16 to prevent it from collapsing and affecting the cutting effect, so that the laser cuts out the predetermined shape on the front piece 16. Then the laser stops, the template machine resets, and the user can open the placket clamping plate 3 to remove the cut-off part of the front piece 16. Then the placket piece 17 is placed in, and the alignment strip 13 aligns the edges of the front piece 16 to complete a placket. Alignment of piece 17 is performed, followed by alignment of another placket piece 17. Due to the presence of the adhesive layer 14, the already aligned placket piece 17 will not shift during the alignment of the other placket piece 17. Finally, the part of the placket piece 17 that does not need to be sewn is folded away from the side away from the second opening 5. Then, the placket pressing plate 3 is placed on the pressing plate 2 of the front piece 16. The template machine is started, and the moving mechanism on the template machine passes through the moving hole 7, thereby moving the moving hole 7 on the working plane of the template machine. Then, the sewing machine is started, and the POLO shirt mold is on the template. Driven by the machine, it moves along a predetermined track. Since the stiff wool 9 is small in size and filamentous, it does not hinder the sewing process while supporting the front piece 16 and the placket piece 17. Thus, the sewing machine head sews the front piece 16 and the placket piece 17 together along the predetermined track. Then the sewing machine stops, the template machine resets, the placket pressing plate 3 is opened, and the folded part of the placket piece 17 and the part glued by the adhesive layer 14 are folded towards the second opening 5. The front piece 16 pressing plate 2 can then be opened, and the front piece 16 with the sewn placket can be removed.
