Description

Technical Field

[0001] This utility model relates to the field of garment sewing auxiliary equipment, and in particular to a mold clamping device for an automatic template machine to sew the outer sleeve seam and make the sleeve vent. Background Technology

[0002] With the development of technology, automated sewing equipment, especially automatic template sewing machines, has been widely used in the garment processing industry. Automatic template sewing machines use a preset template (or template clamp) to fix and guide the fabric, automatically completing the sewing according to a set program, greatly improving production efficiency and sewing accuracy, and reducing reliance on highly skilled operators. However, when using existing automatic template sewing machines to sew sleeves, especially the combination of outer sleeve seams and large sleeve vents, existing template clamp technology still has some shortcomings:

[0003] For example, sleeve sewing typically involves overlapping large and small sleeve pieces (inner and outer fabrics), as well as the folding of the large sleeve placket itself. Ensuring precise positioning between these multiple layers of fabric, and between the fabric and the template reference, is a challenge when placing these layers onto the template. Traditional flat templates or simple pressure blocks often struggle to effectively handle variations in fabric thickness and potential slippage, easily leading to problems such as misalignment and dimensional deviations.

[0004] For example, the production of large sleeve vents requires precise folding. In existing automated template sewing processes, the folding of sleeve vents often requires manual pre-processing by operators before being placed into the template, or relies on auxiliary tools. This not only increases the number of steps and reduces the level of automation, but also makes it difficult to guarantee the accuracy and consistency of manual folding. Although some templates attempt to integrate folding functions, they are often structurally complex or have poor results, making it difficult to achieve convenient and precise online folding and fixing.

[0005] While automated template machines aim to improve efficiency, overly cumbersome processes for loading, positioning, and securing the mold fixtures can negate the advantages of automation. Therefore, simplifying mold fixture operation and reducing auxiliary time while maintaining sewing accuracy is key to improving overall production efficiency.

[0006] In summary, existing technologies still lack a comprehensive solution for high-precision and high-efficiency sewing of sleeve outer seams and large sleeve vents using automatic template machines. This solution effectively addresses the issues of precise positioning of multi-layered fabrics, convenient shaping of complex folds, and stable clamping during the sewing process. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide an automatic template machine mold clamping device for accurately positioning and multi-layered stable clamping of the large sleeve piece, small sleeve piece and sleeve folding part, and clearly guiding the automatic template machine to complete the complex sewing process of sleeve outer seam and large sleeve folding in one go.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] An automatic template machine for sewing the outer sleeve seam and making the large sleeve vent includes:

[0010] The base plate has a first sewing groove and a second sewing groove.

[0011] The small flap is flipped and connected to the base plate. The small flap has a third sewing groove that cooperates with the second sewing groove, and the small flap has a beveled edge for assisting in the folding of the fabric.

[0012] The first flip plate is flipped and connected to the base plate. The first flip plate is provided with a first sewing groove corresponding to the first sewing groove, and a second sewing groove corresponding to the second sewing groove and the third sewing groove.

[0013] And a second flip plate, which is flipped and connected to the first flip plate. The second flip plate is provided with a first through groove corresponding to the first sewing groove and a second through groove corresponding to the second sewing groove.

[0014] Preferably, elastic clamping elements are provided on both sides of at least one or more of the first sewing groove, the second sewing groove, the third sewing groove, the first sewing groove, the second sewing groove, the first through groove, or the second through groove.

[0015] Preferably, the elastic clamping element is a sponge pad; on the base plate, outside or above the elastic clamping element located in the first sewing groove and / or the second sewing groove, a limiting structure for assisting the initial positioning of the fabric is also provided.

[0016] Preferably, the elastic clamping members on both sides of the first sewing groove on the base plate are provided with a plurality of first elastic strips; the elastic clamping members on both sides of the first flip plate are provided with a plurality of second elastic strips; when the first flip plate and the base plate are flipped and overlapped, the first elastic strips and the second elastic strips are in an alternating cooperation state.

[0017] Preferably, the first sewing groove and / or the first sewing channel has an L-shaped profile; the second sewing groove and / or the second sewing channel is inclined.

[0018] Preferably, at least one of the base plate, the small flap, the first flap, and the second flap is made of a transparent or translucent sheet material.

[0019] Preferably, the base plate is composed of a first sewing groove, a second sewing groove, a small flap, a first flap, a second flap, and their respective third sewing groove, first sewing groove, second sewing groove, first through groove, and second through groove, which together constitute a structural unit; at least two sets of structural units are symmetrically arranged on the base plate for sewing at least two sleeve pieces at one time.

[0020] The beneficial effects of this utility model include the following:

[0021] By setting a first and second sewing groove on the base plate, cooperating with a third sewing groove on a flip-up small flip plate, and an oblique edge for assisting fabric folding, and combining a first flip plate (with a first sewing groove corresponding to the first sewing groove and a second sewing groove corresponding to the second and third sewing grooves) and a second flip plate (with a first through groove corresponding to the first sewing groove and a second through groove corresponding to the second sewing groove) that can be flipped and covered sequentially, a multi-layer fabric collaborative positioning, clamping, and sewing guidance system is formed. Through this structural combination, accurate positioning, convenient folding and forming, and stable clamping of the large sleeve piece, small sleeve piece, and sleeve placket folding parts can be achieved. It can also clearly guide the automatic template machine to complete the complex sewing process of the sleeve outer seam and the large sleeve placket in one go, effectively solving the challenges of multi-layer fabric positioning and clamping, the complexity and consistency of large sleeve placket folding and forming, and the integration and guidance efficiency of complex sewing paths.

[0022] By setting multiple first elastic strips in the elastic clamping members on both sides of the first sewing groove of the base plate, and setting multiple second elastic strips in the elastic clamping members on both sides of the first flip plate corresponding to the first sewing groove, the first elastic strips and second elastic strips are in an alternating cooperation state when the first flip plate and the base plate are flipped and overlapped, forming an enhanced, distributed clamping structure for the fabric in the sewing area. Through this alternating cooperation of sponge strips, the density of clamping points is significantly increased and the clamping force is more evenly distributed, effectively preventing relative slippage and local stress concentration of multi-layer fabrics during the sewing process. This further solves the problem of precise positioning and stable clamping of multi-layer fabrics, and improves the sewing accuracy and product quality stability. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments, but these specific embodiments do not limit the scope of protection of the present invention in any way. Example

[0028] like Figure 1-3 As shown, an automatic template machine for sewing the outer sleeve seam and making a large sleeve vent includes a base plate 1, a small flip plate 2, a first flip plate 3, and a second flip plate 4. This template clamping device is mainly used for sewing the outer sleeve seam of garments and making a large sleeve vent. It can achieve precise positioning and efficient sewing, significantly improving production efficiency and product quality.

[0029] The base plate 1 is made of transparent plastic sheet. The base plate 1 has a first sewing groove 5 with an L-shaped outline. Sponge pads 6 are set along the two sides of the first sewing groove 5. A limiting sponge 7 is set above the sponge pads 6, with a height slightly higher than the main sponge pads 6, to form a guide boundary for placing the fabric.

[0030] In the sponge pads 6 on both sides of the first sewing groove 5, several gaps are formed by locally cutting them at certain intervals. First elastic strips 8 are inserted into these gaps. The sponge strips are made of highly elastic rubber sponge material and are bright yellow or orange in color for easy identification by operators. The height of the first elastic strips 8 is slightly higher than the surface of the main sponge pads 6 and is set along the normal direction of the first sewing groove 5.

[0031] A second, inclined sewing groove 9 is provided on the base plate 1 at a certain distance from the end of the short side of the first sewing groove 5. The second sewing groove 9 is also equipped with sponge pads 6 and limiting sponges 7 on both sides, with specifications consistent with those of the first sewing groove 5 area.

[0032] The small flap 2 is connected to the base plate 1 via adhesive tape 10, which is located on the outer edge of the second sewing groove 9. The main body of the small flap 2 is made of transparent plastic sheet. A third sewing groove 11 is machined on the upper surface of the small flap 2, and the direction of this groove is mirror-symmetrical to the second sewing groove 9 of the base plate 1. When the small flap 2 is flipped over and covers the base plate 1, the third sewing groove 11 and the second sewing groove 9 cooperate in space to guide the sewing path of the large sleeve vent. The free end of the small flap 2 is machined into a bevel, and sponge pads 6 are placed on both sides of the third sewing groove 11.

[0033] The first flap 3 is connected to the rear end of the base plate 1 via adhesive tape 10. A first sewing groove 12 is machined on the first flap 3. This groove and the first sewing groove 5 of the base plate 1 form a corresponding spatial relationship when the flap is closed. The sponge pads 6 on both sides of the first sewing groove 12 also adopt a gap-cut design and embed a second elastic strip 13. When the first flap 3 is closed, the second elastic strip 13 and the first elastic strip 8 of the base plate 1 are in an alternating state, similar to the engagement of zipper teeth, so that the large and small sleeve pieces are evenly and firmly clamped in the outer seam area of ​​the sleeve, the clamping force is more evenly distributed, and local stress concentration is effectively prevented. The first flap 3 is also provided with a second sewing groove 14 corresponding to the second sewing groove 9 and the third sewing groove.

[0034] The second flip plate 4, as the outermost covering, is connected to the front end of the first flip plate 3 via adhesive tape 10, forming a layered flip structure. The second flip plate 4 is provided with a first through groove 15 corresponding to the first sewing groove 12 and a second through groove 16 corresponding to the second sewing groove 14. The first through groove 15 and the second through groove 16 are through openings. The sponge pad 6 on the second flip plate 4 plays a final pressing role, and its compression is controlled within an appropriate range to ensure sufficient clamping force while avoiding excessive compression that could lead to sponge fatigue.

[0035] It is worth mentioning that the base plate 1 is composed of a first sewing groove 5, a second sewing groove 9, a small flap 2, a first flap 3, a second flap 4, and their respective third sewing groove, first sewing groove 12, second sewing groove 14, first through groove 15 and second through groove 16, which together form a structural unit. The base plate 1 is provided with two structural units arranged diagonally symmetrically, and the sewing machine can sew two sleeve pieces at one time in sequence according to the symmetrical sewing path.

[0036] The working principle and method of the above-mentioned automatic template machine for sewing the outer sleeve seam and making the large sleeve vent are as follows:

[0037] First, following the order from the outside to the inside, flip up the second flap 4, the first flap 3, and the small flap 2 in sequence to check whether there are any residual threads or debris in each sewing groove of the base plate 1, and ensure that the grooves are clean.

[0038] The second step involves the operator selecting the large sleeve piece to be processed, laying it flat, identifying the outer seam line and the sleeve vent position marks, and using the outline formed by the combination of the limiting sponge 7 as a guide. The large sleeve piece is then placed on the base plate 1, and its position is adjusted so that the outer seam line of the sleeve coincides with the center line of the first sewing groove 5, and the sleeve vent is aligned with the area of ​​the second sewing groove 9. The operator then gently presses the large sleeve piece to ensure it is in full contact with the sponge pad 6, thus initially fixing it in place.

[0039] The third step involves the operator flipping the small flap 2 downwards so that it covers the area above the sleeve vent of the large sleeve piece. The operator checks the fit between the sponge pad 6 of the small flap 2 and the large sleeve piece, locates the edge of the large sleeve piece where the sleeve vent needs to be formed, and folds it upwards along the diagonal edge of the small flap 2. The folding width is adjusted to the design requirements, ensuring that the folding line is straight. The operator then gently presses along the diagonal edge with their fingers to shape the folded part.

[0040] The fourth step involves the operator taking the small sleeve piece, flipping the first flap 3 downwards so that it covers the processed large sleeve piece and the small flap 2, placing the small sleeve piece on the first flap 3 according to the direction of the first sewing groove 12, precisely aligning the edges of the small sleeve piece and the large sleeve piece in the outer seam area of ​​the sleeve, ensuring that the edges of the two pieces of fabric overlap, checking whether the fabric is evenly clamped by the first and second elastic strips 13, and finely adjusting the position of the fabric if necessary.

[0041] Fifth step, the operator flips the second flap 4 downwards so that it covers the entire sleeve assembly, checks whether the second flap 4 is completely attached, presses the second flap 4 with appropriate force to ensure that the sponge pad 6 is fully compressed to achieve the predetermined clamping force, and observes the state of the fabric below through the first and second through slots 16 to confirm that there is no misalignment or wrinkles.

[0042] Step 6: The operator places the assembled mold clamping device into the worktable of the automatic template sewing machine and adjusts the presser foot pressure and sewing speed parameters according to the sewing machine model. The automatic sewing program is then started. The sewing machine needle bar moves along the guide path through the through groove. The first section along the first sewing groove 5 completes the sewing of the L-shaped sleeve outer seam, and the second section along the second and third sewing grooves 11 completes the fixing sewing of the sleeve vent, sewing the sleeve pieces twice in one operation.

[0043] Step 7: After sewing is complete, the operator flips the sleeve pieces upwards in the order of second flap 4, first flap 3, and small flap 2, gently removing the sewn sleeve pieces to avoid damaging the seams or fabric. The sewing quality is then checked, including the straightness of the seams, corner treatment, and the shaping effect of the sleeve vents. A quality assessment and necessary finishing work are then performed.

[0044] In this embodiment, the automatic template machine for sewing the outer sleeve and the mold clamping device for making the large sleeve vent utilizes a multi-positioning guarantee mechanism, including a combination of limiting sponges 7, a positioning pin system, and a triple positioning mechanism of alternating sponge strips, to achieve precise positioning of the large and small sleeve pieces. The fabric positioning accuracy is significantly improved, far exceeding the positioning accuracy of traditional flat mold clamps. The alternating design of the first and second elastic strips 13 greatly increases the density of clamping points, effectively dispersing clamping stress and significantly reducing fabric displacement during the sewing process.

[0045] The precision channel guiding system significantly improves the straightness of the sewing stitches, showing a marked improvement compared to manual control. The corner treatment of the L-shaped sleeve outer seam is more precise, and the consistency of the corner radius is effectively guaranteed. The small flap 2 bevel folding function ensures the consistency of the sleeve pleat fold width, and the sleeve pleat width deviation is strictly controlled in mass production, which is a significant improvement compared to traditional manual folding.

[0046] Through an integrated fabric clamping process, the clamping time for a single sleeve piece is significantly reduced compared to the traditional method, resulting in a marked improvement in efficiency. All sewing processes for the outer sleeve seam and sleeve vent are completed in one clamping operation, reducing the number of workpiece transfers and significantly improving the overall production cycle time.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any innovative improvements or substitutions based on the present invention should fall within the scope of the claims of the present invention. Furthermore, the parameters, materials, and processes mentioned in the above embodiments are not unique. Without departing from the technical essence of the present invention, those skilled in the art can make various alternative choices, and these alternative solutions should also be considered to fall within the scope of protection of the present invention.
