Description

Technical Field

[0001] The utility model relates to the technical field of garment production technology, in particular to a sleeve loop template. Background Art

[0002] The sleeve loop is an important part of woven zipper shirts. It is usually sewn with magic buckles or snap buttons to adjust the size of the cuffs. Depending on the number of pieces produced, the sleeve loop can be divided into two shapes: "a combination of upper and lower layers of pieces" and "a piece folded in half and combined". In the traditional production method, sleeve loops are usually sewn using a flat machine, but this method is relatively inefficient. In order to improve production efficiency, some manufacturers have begun to use templates combined with pattern machines or template machines for production.

[0003] However, existing template machines have some problems when producing sleeve loops. First, after completing one sewing operation, the machine needs to stop running so that the sewn sleeve loop can be manually taken out and a new piece can be inserted and fixed to the template for sewing again. This shutdown process is time-consuming and leads to low production efficiency. Secondly, the design of the fixed template is not flexible enough to adapt to sleeve loops of different sizes, which limits production efficiency. Utility Model Content

[0012] The seventh technical solution is based on any one of the first to sixth technical solutions, wherein the panel is provided with a marking line for placing the cut pieces, and when the upper flap is rotated along the bottom edge of the panel and parallel to the panel, the marking line is covered by the upper flap.

[0013] The eighth technical solution is based on the seventh technical solution, wherein the number of the first sewing areas and the second sewing areas is several and arranged in sequence, and the number of the folding plates and the upper flaps is consistent with the number of the first sewing areas and the second sewing areas and corresponds one to one.

[0015] The tenth technical solution is based on the ninth technical solution, wherein the fixed frame and the replaceable plate are both made of PVC material.

[0016] From the above description of the various embodiments of the present invention, it can be seen that, compared with the prior art, the various embodiments of the present invention have the following beneficial effects:

[0017] In the first technical solution and related embodiments, a template that can be continuously changed is provided, which cleverly separates the originally fixed sleeve loop sewing area, i.e., the first sewing area, from the traditional fixed template and reconstructs it into an independent, replaceable structural unit, which is called a "changeable plate".

[0018] Specifically, the interchangeable plate is composed of a multi-layer structure, with a bottom plate, a panel, a folding plate and an upper flap arranged in sequence from bottom to top. Among them, the bottom plate serves as the bottommost basic support, and is provided with a precise first sewing area for the initial positioning and sewing of the cut pieces. The panel is tightly fixed to the bottom plate, which not only enhances the stability of the overall structure, but also perfectly docks with the first sewing area of ​​the bottom plate through the second sewing area on it, ensuring the accuracy of the cut pieces during the sewing process. The design of the folding plate cleverly solves the problem of folding the cut pieces. It is located above the panel and can rotate relative to the panel, and can fold the cut pieces in half, thereby greatly improving work efficiency and product quality. The upper flap, as the topmost structure, is mainly used to cover the cut pieces, which not only protects the cut pieces from being dislocated, but also facilitates subsequent sewing operations.

[0019] In actual work, when the equipment is sewing the pieces on the first set of interchangeable plates, the operator can simultaneously prepare to fold and place the pieces on the second set of interchangeable plates. This parallel operation design allows the placement and sewing of the pieces to be carried out simultaneously, greatly reducing the equipment's downtime and the number and time of manually taking, placing, and fixing the templates. This continuous mold change design not only achieves efficient operation of the equipment, but also significantly improves the overall production capacity of the production line.

[0020] In the second technical solution and related embodiments, the horizontal side of the T-shape is detachably rotatably connected to the bottom plate, and the cut piece can be placed in the corresponding sewing area when the folding plate is turned over. Then the vertical side of the T-shape presses the cut piece and aligns it with the folded edge of the cut piece to ensure that the cut piece is accurately aligned and folded, thereby ensuring the alignment and stability of the cut piece during the sewing process and avoiding sewing errors caused by shifting of the cut piece.

[0021] In the third technical solution and related embodiments, the overlapping thickness of the base plate and the panel matches the thickness of the fixed frame, which can ensure a close fit between the various parts of the template during assembly, reduce gaps and misalignments, and ensure the overall thickness of the template is consistent. This consistency helps to enhance the structural stability of the template, making it more stable during the sewing process and less prone to deformation.

[0022] In the fourth technical solution and related embodiments, magnets are used as a means to fix the cut pieces. Considering that some old equipment may have a large shaking problem, which may cause the cut pieces to easily move, the use of magnets for fixing can ensure the stability of the cut pieces during the sewing process, prevent the cut pieces from shifting due to equipment shaking, and further ensure the accuracy of the sewing process and product quality, thereby making the template more versatile and able to meet various sewing needs.

[0023] In the fifth technical solution and related embodiments, the relative positions between the fixing frame, the bottom plate and the panel are effectively determined and stabilized by the precisely arranged first alignment protrusions, the first alignment grooves and the second alignment grooves. This alignment design ensures the rapid and accurate positioning of the template during the assembly process, thereby greatly improving production efficiency.

[0024] In the sixth technical solution and related embodiments, the first sewing groove is made according to the maximum size of the sleeve loop. This design takes into account the needs of cutting pieces of different sizes, making the template more widely applicable. In this way, one set of templates can meet the production needs of all sizes, thereby simplifying the production process and improving production efficiency.

[0025] In the seventh technical solution and related embodiments, by setting a marking line on the right-angle edge of one side of the upper flap and the panel, the placement position of the cutting piece can be determined quickly and accurately, thereby reducing the time for adjusting the position of the cutting piece during the sewing process and improving work efficiency.

[0026] In the eighth technical solution and related embodiments, by increasing the number of the first sewing area and the second sewing area, as well as the number of the corresponding folding plates and upper flaps, the template can process multiple pieces at the same time. This not only improves the processing capacity of a single template, but also further improves the overall efficiency of the production line. In addition, this design also provides operators with sufficient time to prepare the pieces of the second set of templates, thereby reducing the downtime of the production line. The advantage of this design is that it can quickly complete the sewing of multiple pieces and shorten the production time of a single product. At the same time, due to the reduction in the time for changing templates and pieces, the downtime in the production process is also effectively controlled.

[0027] In the ninth technical solution and related embodiments, the edge strip is used to effectively fix the folding plate and the upper flap, so that they are stably maintained in the desired position. The user only needs to insert the edge strip into the corresponding slot to complete the installation, which simplifies the installation process.

[0028] In the tenth technical solution and related embodiments, the PVC material has good durability and stability, can withstand the friction of multiple uses and repeated positioning, and is not easy to deform or damage. This prolongs the service life of the template and reduces the cost increase caused by frequent template replacement. At the same time, the PVC material has good waterproof properties, can resist the penetration of water and other liquids, keep the template dry and clean, and ensure that the accuracy of positioning is not affected by moisture or pollution. In addition, the PVC material can be recycled and reused, meeting the requirements of environmental sustainability. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] See also Figures 1 to 7 ,like Figure 1 As shown, the sleeve loop template includes a fixed frame 1 and a replaceable plate 2.

[0045] Fixed frame 1, such as Figure 1 and Figure 2 As shown, it is provided with a hollow area 11 of a hollow structure and a first alignment protrusion 12 protruding from the hollow area 11 along the plane of the fixing frame 1 .

[0046] Replaceable board 2, such as Figure 1 and Figure 3 As shown, there are at least two of them, which are adapted to the hollow area 11 and detachably installed in the hollow area 11. The replaceable plate 2 includes a bottom plate 3, a panel 4, a folding plate 5 and an upper flip plate 6; the bottom plate 3, the panel 4, the folding plate 5 and the upper flip plate 6 are arranged in sequence from bottom to top.

[0047] Bottom plate 3, such as Figure 4 As shown, it is provided with a first sewing area 30, and the first sewing area 30 includes a first sewing groove 31 and a first alignment groove 32. The first sewing groove 31 is used for sewing the piece. In this embodiment, the first sewing groove 31 is made according to the maximum size of the sleeve loop.

[0048] Panel 4, as Figure 5 As shown, the panel 4 is of the same size as the base plate 3 and is fixedly connected. The panel 4 includes a second sewing area 40, which is adapted to the first sewing area 30. The second sewing area 40 includes a first hollow groove 42, a second sewing groove 41, a second hollow groove 43, a second alignment groove 44 and a marking line 45.

[0049] The first hollow groove 42 is located at the folded position of the cutting piece and the groove wall close to the folded edge of the cutting piece coincides with the folded edge of the cutting piece.

[0050] The second sewing groove 41 is matched with the first sewing groove 31 and is the sewing route of the cut piece. At the same time, it is made according to the maximum size of the sleeve loop.

[0051] The second hollow groove 43 is far away from the folded edge of the cut piece and is suitable for installing a magnet.

[0052] The second alignment groove 44 is matched with the first alignment protrusion 12 and the first alignment groove 32, so as to facilitate the installation and fixation of the panel 4 and the bottom plate 3 and to be installed to the hollow area 11 together with the bottom plate 3. In this embodiment, the relative positions between the fixing frame 1, the bottom plate 3 and the panel 4 are effectively determined and stabilized by the precisely arranged first alignment protrusion 12, the first alignment groove 32 and the second alignment groove 44. This alignment design ensures the rapid and accurate positioning of the template during the assembly process, thereby greatly improving the production efficiency.

[0053] The marking line 45 is used for aligning the cut pieces, so as to facilitate the quick placement of the cut pieces.

[0054] In this embodiment, the thickness of the base plate 3 and the panel 4 after being superimposed matches the thickness of the fixed frame 1, which can ensure the close fit between the various parts of the template during assembly, reduce gaps and misalignments, and ensure the overall thickness of the template is consistent. This consistency helps to enhance the structural stability of the template, making it more stable during the sewing process and less prone to deformation.

[0055] Pressed plate 5, such as Figure 1 and Figure 6 As shown, it is adapted to the first hollow groove 42 and is suitable for being installed in the first hollow groove 42 and is detachably rotatably connected to the bottom plate 3 in a direction perpendicular to the bottom edge of the bottom plate 3; specifically, the folding plate 5 is T-shaped, the horizontal side 51 of the T-shape is detachably rotatably connected to the bottom plate 3, and the vertical side 52 of the T-shape presses against the folded edge of the cut piece. The cut piece can be placed in the corresponding sewing area when the folding plate 5 is turned up, and then the vertical side 52 of the T-shape presses the cut piece and aligns it with the folded edge of the cut piece to ensure that the cut piece is accurately aligned and folded, thereby ensuring the alignment and stability of the cut piece during the sewing process and avoiding sewing errors caused by the displacement of the cut piece. In this embodiment, the folding plate 5 is connected to the bottom plate 3 by a retaining strip.

[0056] Upper flap 6, such as Figure 1 and Figure 7 As shown, the upper flap 6 covers the cut piece and is detachably connected to the panel 4 by rotating in a direction parallel to the bottom edge of the panel 4. When the upper flap 6 rotates in a direction parallel to the bottom edge of the panel 4, it covers the cut piece. Specifically, the connection method adopts a baffle strip connection, which includes a third sewing groove 61 and a third hollow groove 62. When the upper flap 6 rotates in a direction parallel to the bottom edge of the panel 4, the marking line 45 is covered by the upper flap 6.

[0057] The third sewing groove 61 is adapted to the first sewing groove 31, is the sewing route of the cut piece, and is made according to the maximum size of the sleeve loop. After the replaceable plate 2 is installed on the fixed frame 1, the first sewing groove 31, the second sewing groove 41 and the third sewing groove 61 overlap.

[0058] In this embodiment, the first sewing groove 31, the second sewing groove 41 and the third sewing groove 61 are all made according to the maximum size of the sleeve loop. This design takes into account the needs of cutting pieces of different sizes, so that the template has a wider range of applications. In this way, one set of templates can meet the production needs of all sizes, thereby simplifying the production process and improving production efficiency.

[0059] The third hollow groove 62 is matched with the second hollow groove 43; in this embodiment, the second hollow groove 43 and the third hollow groove 62 are suitable for installing magnets to fix the cut pieces. Magnets are used as a means to fix the cut pieces. Considering that some old equipment may have a large shaking problem, which makes the cut pieces easy to move, the use of magnets for fixing can ensure the stability of the cut pieces during the sewing process, prevent the cut pieces from shifting due to equipment shaking, and further ensure the accuracy of the sewing process and product quality, so that the template is more versatile and can meet various sewing needs.

[0060] In this embodiment, the marking line 45 is arranged along the right angle edge of the upper flap 6 away from the horizontal edge 51 of the folding plate 5 when the upper flap 6 covers the panel 4. By arranging the marking line 45 on the right angle edge of one side of the upper flap 6 and the panel 4, the placement position of the cut piece can be determined quickly and accurately, thereby reducing the time for adjusting the position of the cut piece during the sewing process and improving work efficiency.

[0061] In this embodiment, the folding plate 5 is connected to the bottom plate 3, and the upper flap 6 is connected to the panel 4 by edge bars, which are used to effectively fix the folding plate 5 and the upper flap 6 so that they can be stably maintained in the desired position. The user only needs to insert the edge bars into the corresponding slots to complete the installation, which simplifies the installation process.

[0062] In this embodiment, the number of the first sewing area 30 and the second sewing area 40 is several and arranged in sequence, and the number of the folding plates 5 and the upper flaps 6 is consistent with the number of the first sewing area 30 and the second sewing area 40 and corresponds one to one. By increasing the number of the first sewing area 30 and the second sewing area 40, and the number of the folding plates 5 and the upper flaps 6 corresponding thereto, the template can process multiple pieces at the same time. This not only improves the processing capacity of a single template, but also further improves the overall efficiency of the production line. In addition, this design also provides operators with enough time to prepare the pieces of the second set of templates, thereby reducing the downtime of the production line. The advantage of this design is that it can quickly complete the sewing of multiple pieces and shorten the production time of a single product. At the same time, due to the reduction in the time for changing templates and pieces, the downtime in the production process is also effectively controlled.

[0063] In this embodiment, the fixed frame 1 and the replaceable plate 2 are both made of PVC material. PVC material has good durability and stability, can withstand the friction of multiple uses and repeated positioning, and is not easy to deform or damage. This prolongs the service life of the template and reduces the cost increase caused by frequent replacement of the template. At the same time, PVC material has good waterproof performance, can resist the penetration of water and other liquids, keep the template dry and clean, and ensure that the accuracy of positioning is not affected by moisture or pollution. In addition, PVC material can be recycled and reused, meeting the requirements of environmental sustainability.

[0064] This embodiment provides a template that can be continuously changed, which cleverly separates the originally fixed sleeve loop sewing area, namely the first sewing area 30, from the traditional fixed template and reconstructs it into an independent, replaceable structural unit, which is called "changeable plate 2".

[0065] Specifically, the interchangeable plate 2 is composed of a multi-layer structure, in which a bottom plate 3, a panel 4, a folding plate 5 and an upper flap 6 are arranged in sequence from bottom to top. Among them, the bottom plate 3 is used as the bottom basic support, and a precise first sewing area 30 is arranged on it for the preliminary positioning and sewing of the cut pieces. The panel 4 is tightly fixed to the bottom plate 3, which not only enhances the stability of the overall structure, but also perfectly docks with the first sewing area 30 of the bottom plate 3 through the second sewing area 40 thereon, ensuring the accuracy of the cut pieces during the sewing process. The design of the folding plate 5 cleverly solves the problem of folding the cut pieces. It is located above the panel 4 and can rotate relative to the panel 4, and can fold the cut pieces in half, thereby greatly improving work efficiency and product quality. The upper flap 6 is the topmost structure, which is mainly used to cover the cut pieces. While protecting the cut pieces from being misplaced, it also facilitates subsequent sewing operations.

[0066] In actual operation, when the equipment is sewing the pieces on the first set of interchangeable plates 2, the operator can simultaneously prepare to fold and place the pieces of the second set of interchangeable plates 2. This parallel operation design allows the placement and sewing of the pieces to be carried out simultaneously, thereby greatly reducing the equipment's downtime and the number and time of manually taking, placing, and fixing the templates. This continuous mold change design not only achieves efficient operation of the equipment, but also significantly improves the overall production capacity of the production line.

[0067] The following uses a piece of cut pieces to sew sleeve loops to illustrate the specific use of the template. If two layers of cut pieces are used or magic buckles are added, only the sewing path groove needs to be changed, and the basic structure of the template remains the same. The equipment used in this embodiment is a pattern machine or a template machine, the fixing frame 1 is fixed to the corresponding position of the pattern machine or the template machine, and two sets of replaceable plates 2 are prepared.

[0068] 1. First, the upper flap 6 of the replaceable plate 2 is opened upwards, and the folding plate 5 is opened to the right. Then, according to the required size, the cut pieces are placed within the marking line 45 of the cut piece placement area.

[0069] ② Next, cover the folding plate 5 and fold the cut piece in half. Then, cover the upper flap 6 to ensure the cut piece is stable.

[0070] ③ Insert the replaceable plate 2 into the hollow area 11 of the fixed plate fixed on the pattern machine or template machine.

[0071] ④ Start the pattern machine or template machine to start sewing. During the sewing process, the operator should follow the above steps 1 and 2.

[0072] Start folding the cut pieces of the second set of interchangeable plates 2 in half and placing them. When the pattern machine or template machine has finished sewing, stop the equipment. Take out the first set of interchangeable plates 2 and place the second set of interchangeable plates 2 with the cut pieces placed in the hollow area 11 of the fixed plate according to step 3. Then restart the equipment and continue sewing. Repeat the above steps to ensure that the interchangeable plates 2 are sewn in rotation without interruption and the cut pieces are continuously placed.

[0073] The present application provides a sleeve loop template, which realizes efficient operation of equipment and improves production efficiency by sequentially rotating the sleeve loop sewing area templates during the production process.

[0074] The description of the above specification and embodiments is used to explain the protection scope of the utility model, but does not constitute a limitation on the protection scope of the utility model. Through the enlightenment of the utility model or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent replacements or other improvements to the embodiments of the utility model or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the utility model.
