Description

Technical Field

[0001] The present application relates to the field of garment cutting, and particularly to a rapid positioning device for garment cutting. Background Art

[0002] The process from making a flat pattern or a three-dimensional cutting pattern of the cloth to cutting the fabric. It includes three types: flat cutting, three-dimensional cutting, and prototype cutting. Flat cutting is to design a flat pattern based on the dimensions measured from the human body, that is, the short measurement cutting method. Three-dimensional cutting is a prototype piece cut from the human body, which conforms well to the requirements of the human body curve. Prototype cutting is a method of cutting garments by adding style relaxation to the prototype cut from the three-dimensional cut garment shape through reasoning. The torso part of the human body has large undulations, and the differences between men and women are also obvious. Different cutting methods should be adopted according to gender and style to make the garment fit well and look beautiful. In terms of technology, garment cutting can also be divided into batch cutting and single-piece cutting.

[0003] Chinese Patent with the publication number CN106283593A discloses a rapid positioning device for garment cutting. In this rapid positioning device for garment cutting, the rotary motor controls the movement of the positioning drill and the slider at the same time, making the positioning fast and accurate. With the setting of the scale, the positioning is more rapid and accurate, and a large amount of manpower is saved at the same time, making the positioning work no longer cumbersome.

[0004] However, this rapid positioning device for garment cutting applies pressure to the fabric with the positioning drill. The contact area between the positioning drill and the fabric is small, and the pressing force is relatively concentrated, which easily damages the fabric, and there are obvious deficiencies. Utility Model Content

[0005] In order to reduce the possibility of the fabric being damaged during garment cutting, the present application provides a rapid positioning device for garment cutting.

[0006] The rapid positioning device for garment cutting provided by the present application adopts the following technical solutions:

[0007] A rapid positioning device for garment cutting includes a workbench. A first portal frame is provided on the workbench. A positioning cylinder is provided on the first portal frame. A first pressing plate is provided on the piston rod of the positioning cylinder. A moving groove is opened on the workbench. A placing plate is slidably arranged in the moving groove. The top surface of the placing plate is flush with the top surface of the workbench. A second portal frame is provided on the workbench. A clamping member is provided on the second portal frame. A pressing member for driving the clamping member to insert into the moving groove is provided on the second portal frame.

[0008] By adopting the above technical solution, during use, one end of the fabric to be cut is placed under the first portal frame. The first pressing plate is driven by a positioning cylinder to press and position, and then the other end is clamped by a clamping member. The pressing member is started to press one end of the fabric downward into the moving groove, which straightens the fabric. On the one hand, compared with the positioning drill pressing and positioning the fabric, the positioning of the first pressing plate and the clamping member is a surface contact with a large contact area, and the fabric is not easily damaged, reducing the possibility of the fabric being damaged during clothing cutting. On the other hand, the fabric is positioned on the workbench, reducing the possibility of the fabric moving during cutting.

[0009] Optionally, a cylinder is provided on one side of the workbench. One end of the cylinder is connected to the placing plate through an adapter plate. Dovetail grooves are provided on the opposite side walls of the moving groove, and the dovetail grooves extend to the end face of the workbench. Dovetail blocks corresponding to the two dovetail grooves are provided on the placing plate, and the dovetail blocks are inserted into the dovetail grooves and are slidably matched with the dovetail grooves.

[0010] By adopting the above technical solution, during use, the cylinder is started, which drives the placing plate to move, thereby adjusting the distance between the first portal frame and the second portal frame, so as to be able to tension and position a long fabric.

[0011] Optionally, scales are provided on the workbench, and the scales are arranged along the length direction of the placing plate.

[0012] By adopting the above technical solution, it is convenient for the operator to accurately control the cutting length.

[0013] Optionally, the clamping member includes a clamping block and a plurality of clamping springs. A clamping groove is provided on the clamping block. One ends of the plurality of clamping springs are commonly connected to a pressing plate, and the end of the pressing plate away from the pressing plate is connected to the side wall of the clamping groove.

[0014] By adopting the above technical solution, during use, the pressing plate is toggled, one end of the fabric is inserted into the clamping groove, and then the pressing plate is released. Under the combined action of the plurality of clamping springs, the pressing plate quickly presses the fabric to achieve clamping.

[0015] Optionally, the pressing member includes a first motor, a lead screw, and a guide rod. The first motor is arranged on the second portal frame. The output shaft of the first motor is coaxially connected to the lead screw. One end of the lead screw penetrates through the clamping block and is threadedly connected to the clamping block. The guide rod penetrates through the clamping block and is slidably matched with the clamping block.

[0016] By adopting the above technical solution, when the first motor is started, the first motor drives the lead screw to rotate. Under the action of the guide rod, the clamping block moves downward and is inserted into the moving groove to achieve pressing on one end of the fabric.

[0017] Optionally, an iron sheet is embedded in the pressing plate, and an electromagnet is arranged in the clamping groove. When the electromagnet is energized, the electromagnet adsorbs the iron sheet, and a plurality of clamping springs are compressed, and there is a distance between the pressing plate and the side wall of the clamping groove.

[0018] By adopting the above technical solution, during use, when the electromagnet is energized, the electromagnet adsorbs the iron sheet, so that a distance is generated between the pressing plate and the clamping groove, which facilitates the operator to pass one end of the fabric through. When the electromagnet is powered off, under the action of a plurality of clamping springs, the fabric can be quickly clamped.

[0019] Optionally, anti-slip grooves are formed in the side wall of the clamping groove, the pressing plate is inserted into the anti-slip grooves and fits with the side wall of the anti-slip grooves, and a rubber pad is arranged on the bottom surface of the pressing plate.

[0020] By adopting the above technical solution, the fabric is pressed into the anti-slip groove by the pressing plate, and the fabric is squeezed by the rubber pad, which increases the contact area between the fabric and the pressing block, also increases the friction force received by the fabric, and reduces the possibility of the fabric sliding during the process of tightening the fabric.

[0021] Optionally, one end of the placing plate facing the second gantry is provided with a protective plate, the cross section of the protective plate is semicircular, and the arc surface of the protective plate faces the second gantry.

[0022] By adopting the above technical solution, through the setting of the semi-circular protective plate, the possibility that the sharp corners of the placing plate pierce the fabric is reduced.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By providing the first gantry, the first pressing plate, the placing plate, the second gantry, and the pressing member, during use, one end of the fabric to be cut is placed under the first gantry, and the first pressing plate is driven by the positioning cylinder to press and position. Then, the other end is clamped by the clamping member, and the pressing member is started to press one end of the fabric into the moving groove, which plays a role in straightening the fabric. On the one hand, compared with the positioning drill pressing and positioning the fabric, the positioning of the first pressing plate and the clamping member is a surface contact, with a large contact area, and the fabric is not easily damaged, reducing the possibility of the fabric being damaged during the clothing cutting process. On the other hand, the fabric is positioned on the workbench, reducing the possibility of the fabric moving during the cutting process;

[0025] 2. By providing the iron sheet and the electromagnet, when the electromagnet is energized, the electromagnet adsorbs the iron sheet, so that a distance is generated between the pressing plate and the clamping groove, which facilitates the operator to pass one end of the fabric through. When the electromagnet is powered off, under the action of a plurality of clamping springs, the fabric can be quickly clamped. Brief Description of the Drawings

Detailed Description of the Embodiments

[0030] The following further describes the present application in detail Figures 1-3 with reference to the accompanying drawings.

[0031] Embodiment 1

[0032] A fast positioning device for clothing cutting provided by the embodiment of the present application, referring to Figure 1 , includes a workbench 1, and the workbench 1 is used to support the entire device and provide a working area for cutting. A first gantry 11 is slidably connected to the workbench 1 for installing and supporting a positioning cylinder 12. The piston rod of the positioning cylinder 12 faces downward, and a first pressing plate 13 is fixed to the end of the piston rod. During use, one end of the fabric is placed under the first pressing plate 13, and the first pressing plate 13 is driven by the positioning cylinder 12 to press down, so as to realize the positioning of one end of the fabric.

[0033] Referring to Figure 1 and Figure 2 , a moving groove 14 is also formed in the workbench 1, and the moving groove 14 extends along the length direction of the workbench 1. A placing plate 15 is slidably arranged inside the moving groove 14, and the fabric can be laid flat on the placing plate 15. The top surface of the placing plate 15 is flush with the top surface of the workbench 1, so that the fabric can smoothly transition from the workbench 1 to the placing plate 15, and the first gantry 11 is arranged on the placing plate 15.

[0034] Referring to Figure 1 and Figure 3, at the other end of the workbench 1, a second gantry 16 is fixedly provided, and a clamping member is installed on the second gantry 16. This clamping member is used to clamp the other end of the fabric. In order to realize the pressing-down function of the clamping member, a pressing member is also installed on the second gantry 16, which is used to drive the clamping member to move downward, pressing the other end of the fabric into the moving groove 14, so as to achieve the effect of stretching the fabric.

[0035] Refer to Figure 1 , Figure 2 and Figure 3 , in order to improve the stability of the movement of the placement plate 15, a cylinder 17 is provided on one side of the workbench 1, and one end of the cylinder 17 is connected to the end face of the placement plate 15 through an adapter plate 18. Dovetail grooves 19 are machined on both side walls of the moving groove 14, and dovetail blocks 110 matching the dovetail grooves 19 are fixed on the side surface of the placement plate 15. The dovetail blocks 110 are inserted into the dovetail grooves 19 and can slide in the dovetail grooves 19. Such a structural design not only restricts the vertical movement of the placement plate 15 but also ensures that the placement plate 15 can move smoothly horizontally along the moving groove 14.

[0036] Refer to Figure 1 , Figure 2 and Figure 3 , in order to facilitate the operator to accurately control the cutting length, a scale 111 is provided on the upper surface of the workbench 1 along the length direction of the placement plate 15. The operator can adjust the position of the placement plate 15 according to the scale 111, so as to ensure the cutting accuracy.

[0037] Refer to Figure 1 , Figure 2 and Figure 3 , the clamping member includes a clamping block 2 and a plurality of clamping springs 21. A clamping groove 22 is formed on the surface of the clamping block 2, and the clamping groove 22 is a through groove. One end of the plurality of clamping springs 21 is commonly connected to a pressing plate 23, and the other end is fixed on the side wall of the clamping groove 22.

[0038] Refer to Figure 1 , Figure 2 and Figure 3 , in order to realize the pressing-down of one end of the fabric, the pressing member includes a first motor 24, a lead screw 25 and a guide rod 26. The first motor 24 is fixed on the top of the second gantry 16, and its output shaft is coaxially connected to one end of the lead screw 25. The other end of the lead screw 25 penetrates through the clamping block 2 and is threadedly connected to the clamping block 2. At the same time, the guide rod 26 also penetrates through the clamping block 2 but is slidably matched with the clamping block 2 to ensure the stable movement of the clamping block 2 in the vertical direction.

[0039] When the first motor 24 is started, the first motor 24 drives the lead screw 25 to rotate. Due to the threaded connection relationship between the lead screw 25 and the clamping block 2, the rotation of the lead screw 25 causes the clamping block 2 to move along the axis direction of the lead screw 25 (i.e., the vertical direction). Under the action of the guide rod 26, the clamping block 2 will maintain a stable moving track and finally press the other end of the fabric into the moving groove 14.

[0040] Referring to Figure 1 , Figure 2 and Figure 3 , in order to improve the convenience when clamping the fabric, an iron sheet 27 is also embedded on the pressing plate 23, and an electromagnet 28 is installed in the clamping groove 22. When the electromagnet 28 is energized, it generates magnetism and adsorbs the iron sheet 27, so that the pressing plate 23 moves towards the top of the clamping groove 22 against the elastic force of the clamping spring 21. In this way, the operator can easily pass one end of the fabric through the clamping groove 22. Once the electromagnet 28 is powered off, the pressing plate 23 will quickly rebound under the combined action of multiple clamping springs 21 and tightly clamp the fabric in the clamping groove 22.

[0041] Referring to Figure 1 , Figure 2 and Figure 3 , in order to prevent the fabric from sliding during the clamping process, anti-slip grooves 29 are also provided on the side walls of the clamping groove 22. A part of the structure of the pressing plate 23 is inserted into the anti-slip grooves 29 and closely fits with the side walls of the anti-slip grooves 29. In addition, the bottom surface of the pressing plate 23 is covered with a rubber pad 210. The rubber pad 210 is soft in material and has a large friction coefficient, which can further increase the friction force between the fabric and the pressing plate 23, thereby effectively preventing the fabric from sliding during the tensioning process.

[0042] In order to further protect the fabric, a protective plate 112 is also fixedly provided at one end of the placing plate 15 facing the second gantry 16. The cross-section of the protective plate 112 is semicircular, and its arc surface faces the second gantry 16. Such a structural design can effectively prevent the sharp corners of the placing plate 15 from piercing the fabric, thereby improving the safety of the fabric during the cutting process.

[0043] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
