Description

Technical Field

[0001] The invention relates to the field of clothing production equipment, and in particular to a marking point printing method and device for clothing spreading fabrics. Background Art

[0002] In the field of clothing manufacturing, cutting is a key link in clothing production and directly affects the quality of the final garment. The traditional clothing cutting process includes the following main steps: first, the clothing cutting layout is carried out according to the designed clothing pattern, and the fabric is laid out after the length of the layout is determined; after the fabric is laid out, the clothing cutting layout is placed on the laid fabric for cutting; after the cutting is completed, all the pieces are coded, and after the coding is completed, the key positions of the pieces are manually pointed and marked to facilitate the subsequent sewing operation and ensure the quality of the garment.

[0003] However, the existing clothing cutting production process has many defects and shortcomings. During the cloth laying process, a layer of paper needs to be placed between each roll of cloth to distinguish it, which increases the production cost; during the cutting process, it is necessary to add a knife edge to the key position, which is not only time-consuming, but also adds extra operation steps; after the cloth is laid, the clothing cutting CAD layout drawing needs to be placed on the cloth for cutting, which causes a waste of labor and materials; after the pieces are cut, they need to be manually coded, which not only increases the labor cost, but also has the problem of contaminating the pieces and coding errors; before sewing, the key positions need to be marked and marked. The point operation requires 2 people, accounting for 5%, and incurs additional costs for brushes and consumables. The actual sewing operation mainly relies on the personal experience of the workers. There is no visible thread indication. Even if someone draws the visible thread, it is impossible to mark all the visible threads clearly, which increases a lot of labor costs. This experience-based operation may lead to production errors, thereby affecting the production quality of the garment. In summary, the existing clothing cutting process has many problems of cost, labor waste and quality risks, and urgently needs to be improved and optimized. Summary of the invention

[0060] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The present invention changes the production process of clothing and creatively uses the scheme and device of printing before cutting. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0061] Embodiment 1:

[0062] like Figure 1 As shown, a marking point printing method for clothing spread fabrics is used to print the positions to be marked on N pieces of spread fabrics, and the method comprises the following steps:

[0063] S1: Determine the length of the spreading area. Through the clothing cutting layout diagram and the clothing cutting manual layout diagram, according to the actual situation of the fabric, first measure and determine the total length of the spreading area, so as to provide an accurate size basis for the subsequent spreading and printing process;

[0064] S2: Fix the first layer of fabric on the fabric spreading area to ensure that the fabric will not be displaced or wrinkled in subsequent operations, thereby ensuring the accuracy of the printing position;

[0065] S3: Print the required marking position of the first layer of fabric. Use an inkjet printer, laser printing equipment or other suitable marking equipment to accurately print the predetermined marking position on the fabric. The marking position is usually set in advance according to the design requirements to ensure that the subsequent printing and cutting can be completed accurately through the marking;

[0066] S4: Fix the second layer of fabric on the first layer of fabric, and print the required marking position of the second layer of fabric. Lay the second layer of fabric on the fixed first layer of fabric and fix it in the same way. Then, use the same printing device to mark the marking position on the second layer of fabric to ensure that it is consistent with the first layer;

[0067] S5: Repeat step S4, and fix the remaining N-2 sheets of fabric and print the positions to be marked. Spread and fix the subsequent fabrics layer by layer, and print the positions to be marked on each layer of fabric until all N layers of fabric are laid and marked.

[0068] In this method, by spreading, fixing and printing the spreading fabric layer by layer, the marking point printing operation of the multi-layer fabric can be realized efficiently and accurately. First, the length of the spreading area is determined, and the coordinate position that needs to be fixed is determined through the graphics in the clothing cutting layout diagram. The first layer of the spread fabric is fixed on the needle tip through the needle fixing device to ensure that each layer of fabric can cover the entire area when fixed, and then the printing device is used to accurately mark the position to be marked on each layer of fabric. Each layer of fabric is fixed and marked with marking points through the same steps, thus avoiding position deviation between fabric layers and ensuring printing accuracy. By fixing the spread fabric layer by layer and printing at the marking position of each layer of fabric, it can ensure that the marking points are consistent on each layer of fabric, avoiding marking errors caused by misalignment between layers, thereby improving the accuracy of fabric processing. This method simplifies the marking point printing operation of multi-layer fabrics, avoids the tedious steps of processing each layer of fabric individually, and is suitable for large-scale spreading and processing needs, thereby greatly improving production efficiency. This method is suitable for various types of fabric marking, especially for occasions where multi-layer spread fabrics need to be marked synchronously, such as clothing cutting, home textile fabric processing, etc.

[0069] like Fig.10As shown, determining the length of the spreading area specifically includes: determining the length of the required spreading area through a clothing cutting layout diagram or a clothing cutting manual layout diagram, the layout diagram provides the specific position and size of each piece, so that the logo printing position can be determined through the clothing cutting CAD software and the through-hole position on the cutting spreading table, and the subsequent coding, knife edge line, key position line, bright line and other process markings can be completed at one time. By using the cutting layout diagram or the manual layout diagram, the length of the spreading area can be accurately determined, and the fabric utilization rate is improved. The layout diagram accurately calculates the distribution position and size of the pieces, so that the determination of the spreading length is more scientific and reasonable, and unnecessary fabric waste in the spreading process is reduced. The layout diagram can be adjusted according to different production needs or fabric types. Whether it is large-scale production or small-batch customization, the length of the spreading area can be flexibly adjusted through the layout diagram, and various logos can be printed to adapt to different production modes.

[0070] The acupuncture fixing device includes a positioning needle, a positioning column, a cutting and spreading table, a spreading machine, a lifting mechanism, a lifting plate, an electric push rod and a control system. The cutting and spreading table is provided with a spreading machine on the top, and a plurality of vertically arranged electric push rods are provided below the cutting and spreading table. The top of the electric push rod is provided with a positioning needle, the lifting mechanism is provided on the cutting and spreading table, and the lifting mechanism drives the lifting plate to rise and fall. The lifting plate is located directly above the cutting and spreading table, and the control system is applied to the positioning needle, the cutting and spreading table, the spreading machine, the lifting mechanism, the lifting plate, and the electric push rod;

[0071] The step of fixing the first layer of the spread fabric with the coordinate group as a fixed position by a needle-punching fixing device comprises:

[0072] First determine the coordinates of the positioning pin, the selected positioning pin extends out from the upper surface of the cutting and spreading table, the cloth is spread on the top of the needle tip of the positioning pin exposed on the cutting and spreading table through the spreading machine, the lifting mechanism drives the lifting and pressing plate to press down, and the printed cloth is pressed above the cutting and spreading table. At this time, the needle tip of the positioning pin penetrates the positioning cloth.

[0073] The positioning pin plays a key fixing role. Through the electric push rod and positioning column, the positioning pin extends at the predetermined coordinate position. The cloth spreading machine performs cloth spreading operations on the cutting and spreading table. It first moves to one end of the printer through the slide rail for spreading. It can also be spread manually. After laying, the positioning pin supports the fabric, and two people assist in flattening the fabric to ensure that the fabric fixed by the positioning pin is flat and that the printer prints accurately. After printing, the second layer of fabric is laid until the load-bearing requirements or spreading requirements of the fixed pin are met. The lifting mechanism drives the lifting and lowering plate to press the fabric, and the needle tip of the positioning pin penetrates the fabric to play a precise fixing role. The entire operation is automatically managed by the control system to ensure the accuracy and stability of the fabric during multi-level marking and cutting. Through the coordinate positioning and acupuncture of the positioning pin, the fabric can be accurately fixed to ensure that the fabric will not move or deviate in position during cutting. The cooperation of the cloth spreading machine, lifting mechanism and control system realizes the fully automated operation of spreading, pressing and fixing, reduces manual intervention and improves work efficiency.

[0074] The printing content of the printer can be customized. According to the clothing cutting and production requirements, the printer can be controlled by the control system to print the laying fabric. The printer can be one or more and assembled according to the cutting requirements.

[0075] In step S2, the coordinates of the fixing device to be installed are set according to the graphics in the clothing cutting layout diagram or the clothing cutting manual layout diagram according to the cutting requirements.

[0076] In step S2, the coordinates required for fabric fixing are accurately set through the graphics of the clothing cutting layout or the manual layout, and the fixing device is installed at these coordinate positions so that the fabric can be firmly fixed during the subsequent spreading and pressing process. Through the precise guidance of the cutting layout, the cutting position of each layer of fabric is ensured to be highly consistent with the fixing point to avoid fabric displacement or misalignment.

[0077] In step S2, the first layer of fabric is fixed by placing a sticky object on the clothing cutting and spreading table to fix the first layer of fabric, and then continuing to place the sticky object on the first layer of fabric to lay the second layer of fabric until the spreading operation is completed.

[0078] In this embodiment, adhesives such as double-sided tape or removable tape are used to fix the fabric layer by layer. During the laying process, the adhesive plays a temporary fixing role to prevent the fabric from displacement or wrinkles during laying and subsequent processing. The bonding between each layer of fabric ensures that the multi-layer fabric can fit tightly and avoids errors in multi-layer cutting or marking. At the same time, the use of adhesives can simplify the operation steps and reduce complex mechanical fixing equipment.

[0079] After the needle tip of the positioning needle penetrates the fabric, step S2 is repeated until the positioning needle tip meets the load-bearing requirement or the number of layers to be laid is reached. The lifting mechanism drives the lifting and pressing plate to press down, pressing the printed fabric down to the top of the cutting and laying table. At this time, the needle tip of the positioning needle penetrates the laid fabric until the laying operation is completed.

[0080] This embodiment achieves precise fixation of multi-layer fabrics by needle-punching the fabrics layer by layer with the positioning needle. The needle tip of the positioning needle can penetrate the fabrics to be spread layer by layer, playing a key role in the fixation process of the multi-layer fabrics, ensuring that each layer of fabric is tightly fitted with the cutting and spreading table. At the same time, the lifting mechanism drives the lifting and pressing plate to press each layer of printed fabric layer by layer, ensuring the stability and accuracy of the spreading operation. The needle tip of the positioning needle not only fixes the fabrics, but also can bear the weight of the multi-layer fabrics until the required number of spreading layers is reached or the load-bearing requirements are met.

[0081] The control system includes a clothing cutting CAD layout drawing system, an electric push rod control system, a printer control system, a spreading machine control system and a lifting and lowering plate control system. The coordinate group that needs to be fixed is determined through the graphics in the clothing cutting drawing, and the selected positioning needle tip extends out of the upper surface of the cutting and spreading table. The fabric is spread on the top of the positioning needle tip exposed on the cutting and spreading table through the spreading machine.

[0082] The control system integrates multiple subsystems, obtains graphic data through the clothing cutting CAD layout drawing system, and uses the electric push rod control system to accurately control the extension position of the positioning needle. The cloth spreading machine control system is responsible for automatically laying the fabric to ensure that the fabric remains flat on the cutting and spreading table. The lifting and lowering plate control system presses the laid fabric to fix each layer of fabric, and the needle tip of the positioning needle penetrates the fabric to complete the fixation. In addition, the printer control system automatically prints on the fabric according to the cutting layout diagram to ensure the accuracy of subsequent processing.

[0083] The positions to be marked in step S3 include codes, knife edges, visible lines, points and custom marking symbols.

[0084] In step S3, the printer control system will accurately print the information to be marked on the fabric. These marks include key positions such as coding, knife lines, visible lines, and dots, and can add custom symbols and information. The printer control system will automatically mark all required marks on the fabric according to the preset clothing layout diagram and symbol definition library to ensure that the fabric can be processed according to the predetermined process during subsequent cutting, sewing and processes.

[0085] like Figure 3-Figure 6 As shown, a needling fixing device for a spreading fabric is provided, which is used to implement the step of fixing the first layer of fabric in step S2 of claim 1 or 2, comprising a supporting mechanism 1, on which a printing mechanism 2 is provided, and further comprising:

[0086] A needle-punching fixing device 4, which is arranged on the supporting mechanism 1, and is used to perform needle-piercing on the laid cloth printed by the printing mechanism 2;

[0087] The pressing mechanism 5 is arranged on the supporting mechanism 1, and is used for pressing the cloth so that the needle-punching fixing device 4 can completely penetrate the fabric.

[0088] The printing mechanism 2 includes a printer 3 .

[0089] Each component is stabilized by the support mechanism 1. The position of the coordinate group that needs to be fixed is first determined by the graphics in the clothing cutting layout diagram. The positioning needle of the selected acupuncture fixing device extends out of the upper surface of the cutting and spreading table. The cloth is laid on the top of the needle tip of the positioning needle exposed on the cutting and spreading table manually or by a spreading machine. After the printer performs the printing operation, the lifting mechanism drives the lifting and pressing plate to press down, and presses the printed fabric to the top of the cutting and spreading table. At this time, the needle tip of the acupuncture fixing device penetrates the cloth.

[0090] The step S2 determines the coordinate group that needs to be fixed on the spreading fabric, and uses the positioning needle of the acupuncture fixing device to fix the first layer of spreading fabric with the coordinate group as the fixed position. The steps include: first determining the position of the coordinate group that needs to be fixed, manually or automatically passing the positioning column and the positioning needle of the acupuncture fixing device through the through hole from above the cutting and spreading table and placing them on the base frame, manually or by a spreading machine laying the cloth on the top of the needle tip of the acupuncture fixing device exposed on the cutting and spreading table, and performing the printing operation. The lifting mechanism drives the lifting and lowering plate to press down, and presses the printed cloth to the top of the cutting and spreading table. At this time, the positioning needle of the acupuncture fixing device penetrates the cloth.

[0091] The acupuncture fixing device uses manual or automatic equipment to place the positioning columns and positioning needles on the base frame through the through holes above the cutting and spreading table. The automatic equipment includes various types, and its purpose is to place the positioning columns and positioning needles without error on the coordinate group that needs to be positioned.

[0092] By stabilizing each component through the support mechanism 1, the printer 3 prints the specified position of the laid cloth, and the pressing mechanism 5 applies pressure to the cloth by lifting the pressure plate 52, so that the positioning needle 42 completely penetrates the cloth, thereby realizing the precise positioning and marking of the cloth. The pressing mechanism 5 can be equipped with a downward pressure sensor, and according to the thickness of the cloth fixed by the positioning needle, the cloth is compacted and returned. The above device can effectively improve the accuracy of clothing cutting and marking, and reduce the error of manual intervention. Especially in the positioning of multi-layer cloth, the coordinated use of the acupuncture fixing device 4 and the pressing mechanism 5 ensures that each layer of cloth can be accurately positioned, which greatly improves the production efficiency and product quality. At the same time, by controlling the operation of the acupuncture fixing device and the printer, the labor intensity is significantly reduced.

[0093] The positioning pins 42 of different lengths and strengths can be selected according to the material and thickness of the cloth, and the thrust of the electric push rod 41 can also be adjusted to meet different operating requirements. The lifting and lowering pressure plate 52 of the pressing mechanism 5 can be replaced with pressure plates of different shapes and sizes, and pressed down as a whole or in blocks to adapt to cloths of different widths. In addition, the nozzles of the printer 3 can also be selected in different models, using high-temperature disappearing ink, water-washing disappearing ink or other inks to meet the printing requirements of various colors and precisions.

[0094] The supporting mechanism 1 includes a base frame 11, a plurality of legs 12 are fixed at the bottom of the base frame 11, a supporting rod 13 is fixedly installed on the top of the base frame 12, a fixing frame 14 is fixed in the middle of the supporting rod 13, and a cutting and spreading table 15 is fixedly connected to the top of the supporting rod 13. The base frame 11 provides stable support for the overall structure, and the legs 12 ensure that the device is firmly on the work surface; the supporting rod 13 provides longitudinal support and connects various functional components, and the fixing frame 14 is used to stabilize the electric push rod 41, the positioning column 44, and the positioning needle 42 to ensure that they remain stable during operation. The cutting and spreading table 15 serves as the basic table for laying and processing cloth, and provides a stable operating platform for positioning acupuncture and pressing. The supporting structure is simple and stable in design, effectively supports and connects various operating units, ensures stability and reliability during the working process, and through reasonable support and fixing design, not only the overall stability of the equipment is improved, but also the installation and maintenance of each unit are simplified.

[0095] The size and position of the support rod 13 and the fixing frame 14 can be adjusted as needed. The support leg 12 of the base frame 11 can be designed as a height-adjustable structure to meet the height requirements of different work surfaces. In addition, the material of the cutting and spreading table 15 can be made of different wear-resistant and lightweight materials so that it can be flexibly used in different usage environments.

[0096] The acupuncture fixing device 4 includes a plurality of electric push rods 41, a positioning column 44, and a positioning needle 42. The fixed ends of the electric push rods 41 and the positioning column 44 are vertically fixed on the top of the base frame 11. The output ends of the electric push rods 41 and the positioning column 44 are fixedly connected with the positioning needle 42. The electric push rods 41 drive the positioning needle 42 to extend or retract according to the control signal. When the electric push rods 41 are in the retracted state, the positioning needle 42 is lower than the plane of the cutting and spreading table. When the electric push rods 41 are in the extended state, the positioning needle 42 fixes the fabric according to the positioning requirements of the fabric, and realizes the precise insertion of the part of the fabric that needs to be positioned. Through the coordinated work of multiple electric push rods 41, the actions of multiple positioning needles 42 can be controlled at the same time to ensure the simultaneous positioning and penetration of multiple points of the fabric. Using the electric push rods 41 to drive the positioning needle 42 can accurately control the insertion depth and position of the positioning needle to ensure the precise positioning of the fabric. At the same time, through automatic control, the complexity of manual operation is greatly reduced, and the operating efficiency and positioning accuracy of the equipment are improved. One end of the positioning column 44 is fixedly connected to a positioning pin 42. After determining the coordinate group that needs to be fixed, multiple positioning columns 44 and positioning pins 42 are placed manually or automatically to ensure simultaneous positioning and penetration of multiple points of the cloth, complete cloth positioning, and prepare for printing.

[0097] The thrust and stroke of the electric push rod 41 can be adjusted according to the thickness and material of the cloth to achieve the best penetration effect. The material of the positioning needle 42 can be selected from steel needles with different hardness and surface treatment to adapt to the characteristics of different cloths. In addition, the number of electric push rods 41 can be increased or decreased as needed to meet the positioning requirements of cloths of different sizes.

[0098] The electric push rod 41 is located between the base frame 11 and the cutting and spreading table 15. The electric push rod 41 is installed on the top of the base frame 11 and extends or retracts under the cutting and spreading table 15. This installation method allows the positioning needle 42 to smoothly pass through the through hole of the cutting and spreading table 15 during operation, accurately locate and penetrate the cloth. By installing the electric push rod 41 between the base frame 11, the fixed frame 14 and the cutting and spreading table 15, the positioning needle 42 can penetrate the cloth more accurately and stably. This layout optimizes the overall structure of the equipment, reduces space occupancy, and ensures the stability of the positioning needle 42 when penetrating the cloth.

[0099] The installation position of the electric push rod 41 can be adjusted, or push rods of different models can be used to meet the requirements of space and force. In addition, the installation of the electric push rod 41 can be made more flexible and convenient by changing the structural design of the base frame 11.

[0100] The length of the positioning column 44 can be adjusted according to the thickness and material of the cloth to achieve the best penetration effect. The material of the positioning needle 42 can be selected from steel needles with different hardness and surface treatment to adapt to the characteristics of different cloths. In addition, the number of positioning columns 44 and positioning needles 42 can be increased or decreased as needed to meet the positioning requirements of cloths of different sizes.

[0101] A plurality of through holes 43 are provided on the cutting and spreading table 15. The through holes 43 and the electric push rod 41 are on the same vertical axis. The design of the through holes 43 corresponds precisely to the position of the electric push rod 41, so that the positioning needle 42 can smoothly pass through the through holes and penetrate into the cloth. In this way, when the electric push rod 41 is extended, the positioning needle 42 extends from the upper surface of the cutting and spreading table 15 through the through holes 43 to achieve the identification and positioning of the cloth. By providing the through holes 43 on the cutting and spreading table 15, the positioning needle 42 can pass through the cloth without hindrance, thereby improving the accuracy of cloth positioning and the working efficiency of the device. This design can also reduce the damage that may be caused to the cloth surface by the equipment during operation, thereby ensuring the quality of the cloth.

[0102] The distances between through holes, positioning pins, positioning posts, and electric push rods are determined based on the production requirements for garment cutting. The purpose is to ensure that the graphics in the garment cutting layout can be precisely positioned, and that there are no errors in the cut pieces and all printed content.

[0103] The diameter and number of the through holes 43 can be adjusted according to the needs of different fabrics to adapt to different operating requirements. A more wear-resistant material can be used to make the cutting and spreading table 15 to reduce the wear of the through holes. The shape of the through holes can also be designed as long grooves and reinforced to stabilize the positioning needles and increase the applicability of the device.

[0104] A slide rail is installed on the long side of the cutting and spreading table 15, and the spreading machine 40 and the printer 3 slide on the cutting and spreading table 15 through the slide rail. The slide rail is installed on the long side of the cutting and spreading table 15, and is used to guide the spreading machine 40 and the inkjet printer 3 to move in different directions along the slide rail. The setting of the slide rail enables the spreading machine 40 to lay the cloth smoothly and enables the printer 3 to print. By controlling the movement range of the slide rail and the position of the equipment on the slide rail, continuous laying and printing of the cloth are achieved. The setting of the slide rail simplifies the movement control of the spreading machine 40 and the inkjet printer 3, making the cloth laying and printing process smoother and more efficient. This design can shorten the time for cloth laying and printing, improve overall production efficiency, and reduce the need for manual operation. At the same time, the application of the slide rail ensures the accuracy of cloth laying and printing.

[0105] The length and position of the slide rail can be adjusted according to the size of the table, or multiple slide rails can be installed to increase the stability and flexibility of the equipment. If you need to increase the smoothness of movement, you can add rollers or sliders to the slide rail to reduce the friction of the equipment. In addition, you can also increase the service life of the equipment by improving the material of the slide rail, such as using wear-resistant aluminum alloy or stainless steel.

[0106] When the electric push rod 41 is in an extended state, the portion of the positioning pin 42 extending from the cutting and spreading plate 15 is a first spacing, and the spacing between the spreading machine or printing mechanism 3 and the upper surface of the cutting and spreading plate 15 is a second spacing, and the first spacing is smaller than the second spacing.

[0107] It ensures that after the cloth is pierced by the positioning needle 42, it will not interfere with the operating space of the cloth spreading machine 2 and the printer 3. This spacing design ensures that the cloth laying, printing and positioning actions are independent of each other and are not interfered with. The reasonable design of the spacing ensures the coordinated work between the various operating modules, so that the cloth spreading, printing and positioning actions can be carried out continuously and smoothly. By maintaining the extension distance of the positioning needle 42 and the working distance of the equipment, mutual interference between the equipment is avoided, thereby improving the overall work efficiency and equipment safety.

[0108] The first and second spacings can be adjusted according to the specific fabric thickness and equipment requirements to adapt to different operating requirements. Sensors can be used to monitor and adjust the spacing in real time to ensure that the extension distance of the positioning needle 42 always remains in the optimal state. In addition, the spacing can also be adjusted through a mechanical limit device to improve the reliability of equipment operation.

[0109] The pressing mechanism 5 includes a lifting device 51 fixed on the base frame 11, the lifting device 51 is vertically downward, and a lifting and pressing plate 52 is fixed at the output end. A plurality of limiting holes 53 are provided on the lifting and pressing plate 52, and the limiting holes 53 and the through holes 43 are on the same vertical axis. The lifting device 51 drives the lifting and pressing plate 52 to move in the vertical direction, and the limiting holes 53 on the lifting and pressing plate 52 are designed to correspond to the through holes 43. When the lifting device 51 drives the lifting and pressing plate 52 to press down, the limiting holes 53 can guide the positioning needle 42 to accurately penetrate the cloth. This structure ensures that the path of the positioning needle 42 is accurate during pressing, making the positioning of the cloth more reliable. Through the design of the lifting and pressing plate 52, the cloth can be effectively pressed into place, and the penetration positioning of the positioning needle 42 can be ensured. The design of aligning the limiting holes 53 with the through holes 43 provides precise guidance, avoids the displacement or skewness of the positioning needle 42, and greatly improves the positioning accuracy and repeatability. The shape and size of the lifting plate 52 can be adjusted according to the actual width of the cloth, and the layout of the limiting holes 53 can also be optimized as needed. The lifting device 51 can select different driving modes, such as pneumatic, hydraulic or servo motor drive, to adapt to different operating environments and requirements. In addition, the material of the pressure plate can be rubber or other flexible materials to reduce indentations and damage to the cloth.

[0110] The pressing mechanism 5 includes a lifting device 51 fixed on the cutting and spreading table 15, the lifting device 51 is vertically downward, and a lifting and lowering plate 52 is fixed to the output end of the lifting device 51. A plurality of limiting holes 53 are formed on the lifting and lowering plate 52, and the limiting holes 53 and the through hole 43 are on the same vertical axis.

[0111] The cutting and spreading table is an operating platform for the spreading fabric, and the top is used to place the spreading fabric. The cutting and spreading table surface is designed with through holes 43, so that a fixing mechanism such as a positioning needle or other acupuncture equipment can be fixed at a required position, and the puncture fabric is fixed.

[0112] Printing mechanisms 2 and printers 3 are installed on both sides of the cutting and spreading table 15. The printing mechanisms are used to print various marks on the fabric, including the marking symbols such as the knife edge, exposed line, and dot position mentioned in step S3. These marks provide guidance for operators in the subsequent cutting and sewing process to ensure that the fabric is accurately cut and processed.

[0113] The lifting device 51 is vertically installed above the cutting and spreading table 15, and its output end is connected to the lifting and lowering plate 52. The lifting device controls the pressing or rising operation of the lifting and lowering plate through vertical movement, thereby pressing the fabric on the cutting table. During the pressing process, the fabric is fixed by adhesive or acupuncture.

[0114] In summary, a method for printing marking points on clothing spreading fabrics is a clothing cutting production process, which includes first fixing the spreading fabrics, then printing, and then pressing the fabrics down until the spreading operation is completed, and then cutting is performed.

[0115] Embodiment 2 is different from Embodiment 1:

[0116] like Figure 2 As shown, a marking point printing method for clothing spread fabrics is also provided, which is used to print the positions to be marked on N pieces of spread fabrics, and the marking point printing method includes:

[0117] S1. Determine the length of the spreading area;

[0118] S2, determining a coordinate group that needs to be fixed on the paving fabric, and fixing the first layer of paving fabric with the coordinate group as a fixed position using a needle-punching fixing device;

[0119] S3, printing the position to be marked on the first layer of fabric;

[0120] S4, fixing a second layer of paving fabric on the first layer of paving fabric, and printing a position to be marked on the second layer of paving fabric;

[0121] S5, repeat step S4, and fix the remaining N-2 pieces of fabric and print the positions to be marked, until the fabric spreading operation is completed.

[0122] like Figure 8-Figure 9 As shown, the step of fixing the coordinates to be fixed by the cutting cloth spreading table and the multiple through holes and the lifting mechanism provided on the cutting cloth spreading table also includes: determining the coordinates of the through holes by the graphics in the clothing cutting layout diagram, placing multiple positioning posts 44 with positioning pins 42 fixed on the tops of the through holes 43 of the determined coordinates, spreading the first layer of cloth spreading fabric on the tops of the positioning pins 42, and the printer 3 performs a printing operation, and after the printing operation is completed, laying the second layer of fabric and performing printing until the cutting requirements or the bearing range of the positioning pins are met;

[0123] The lifting mechanism drives the lifting plate to press down, pressing the printed fabric to the top of the cutting and spreading table. At this time, the needle tip of the positioning needle penetrates the laid fabric, and the above operation is repeated until the spreading operation is completed.

[0124] Through the through hole 43, the positioning column 44 and the positioning pin 42, the fabric to be laid is positioned and fixed. First, the coordinate group of the position to be fixed is determined according to the figure in the clothing cutting layout diagram, and then the positioning column 44 and the positioning pin 42 are placed on the through hole 43 to complete the fixation. This ensures the consistency of the marking position of each layer of fabric and avoids the displacement of the fabric during cutting or processing. The function of the lifting and lowering plate is to further press the fabric on the platen to ensure that the fabric is flat and stable.

[0125] By determining the coordinates of the through holes through the graphics in the clothing layout diagram and inserting the positioning posts and steel needles at the corresponding positions, it can ensure that the fixing points of each layer of fabric are accurate, which helps to improve cutting accuracy and fabric utilization. The steel needles of the positioning posts directly penetrate the fabric and firmly fix it on the cutting and spreading table, avoiding errors and defects caused by movement of the fabric during the cutting process, ensuring the accuracy and quality of the finished product. The fixing device cooperates with the automatic operation of the lifting mechanism and the pressing plate, reducing the manual operation steps and greatly improving production efficiency. It is particularly suitable for large-scale industrial production.

[0126] Embodiment 3 is different from Embodiment 1:

[0128] Printing is performed by a printer 3 of a printing mechanism 2;

[0129] After the printing is completed, the adhesive is placed on the first layer of fabric, the second layer of fabric is laid, and the printing is performed by the printer 3 of the printing mechanism 2;

[0130] By bonding the fabric, the fabric is prevented from shifting and tilting, which helps to ensure the accuracy of subsequent cutting. Repeat the above steps until the fabric spreading operation is completed.
