Description

Technical Field

[0001] This invention relates to the field of garment production equipment, specifically to a method and apparatus for printing marking points on garment fabric. Background Technology

[0002] In the garment manufacturing industry, cutting is a crucial step in garment production, directly affecting the quality of the final garment. Traditional garment cutting processes include the following main steps: First, based on the designed garment pattern, a pattern is laid out, and after determining the length of the pattern, the fabric is laid out. After the fabric is laid out, the garment pattern is placed on top of the laid-out fabric for cutting. After cutting, all pieces are marked. Following marking, key positions on the pieces are manually marked to facilitate subsequent sewing operations and ensure the quality of the finished garment.

[0003] However, existing garment cutting and production processes have many defects and shortcomings. During fabric laying, a layer of separating paper is needed between each roll of fabric to distinguish them, which increases production costs. During cutting, incisions need to be made at key locations, which is not only time-consuming but also adds extra steps. After the fabric is laid out, a garment cutting CAD layout needs to be placed on top of the fabric for cutting, resulting in a waste of labor and materials. After the cut pieces are finished, they need to be manually marked, which not only increases labor costs but also poses problems such as contaminating the cut pieces and marking errors. Before sewing, key locations need to be marked and marked. The thread is used to assist in subsequent sewing operations. Assuming approximately 40 employees per production line, point-by-point operation requires 2 people, accounting for 5%, and incurs additional costs for drawing tools and consumables. The actual sewing operation mainly relies on the individual experience of the workers. There are no visible thread indicators, and even if someone draws visible threads, it is impossible to clearly mark all the threads, which also increases labor costs significantly. This experience-based operation method may lead to production errors, thereby affecting the quality of finished garments. In summary, the existing garment cutting process has multiple problems of cost, labor waste, and quality risks, and urgently needs improvement and optimization. Summary of the Invention

[0046] This method and device for printing markings on garment fabric uses a needle-punching fixing device to fix the fabric in place, allowing printing directly onto the fabric and eliminating the need for a separating paper. This not only reduces material costs but also minimizes waste generated during production, thus benefiting the environment. By printing key locations on the cut pieces, the step of adding cutting edges required in traditional processes is eliminated, significantly reducing cutting time and improving production efficiency. Marking on the cut pieces avoids potential contamination and errors during manual marking, improving accuracy and significantly reducing labor costs. Printing allows for the completion of marking points and topstitching on the cut pieces in one step, eliminating the need for manual marking and topstitching before sewing, greatly reducing manpower and material costs. Furthermore, printing eliminates the need to place garment cutting CAD drawings on top of the fabric for cutting; the CAD drawings can be directly printed on the top layer of fabric for direct cutting. Completing all preparations before garment cutting enhances a company's competitiveness, ensuring its survival and reducing unemployment, thereby strengthening the nation's overall competitiveness.

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The present invention changes the garment production process by creatively using a method and apparatus of printing before cutting. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] Example 1:

[0062] like Figure 1 As shown, a method for printing markings on garment fabric is used to print the positions to be marked on N pieces of fabric. The method includes the following steps:

[0063] S1: Determine the length of the fabric laying area. Using garment cutting layout diagrams and manual garment cutting layout diagrams, measure and determine the total length of the fabric laying area based on the actual condition of the fabric to provide accurate dimensional basis for the subsequent fabric laying and printing process;

[0064] S2: Lay and secure the first layer of fabric in the laying area. This ensures the fabric will not shift or wrinkle during subsequent operations, thus guaranteeing the accuracy of the printing position;

[0065] S3: Print the markings at the designated locations on the first layer of fabric. Use an inkjet printer, laser printer, or other suitable marking equipment to accurately print the predetermined markings on the fabric. The marking positions are usually set in advance according to design requirements to ensure accurate completion during subsequent marking and cutting processes.

[0066] S4: Secure the second layer of fabric onto the first layer of fabric, and print the markings required on the second layer. Lay the second layer of fabric on top of the secured first layer and secure it in the same manner. Then, use the same printing equipment to mark the markings on the second layer of fabric, ensuring they are consistent with the first layer.

[0067] S5: Repeat step S4 to lay and fix the remaining N-2 fabric layers and print the markings at the required locations. Lay and fix the subsequent fabric layers one by one, and print the markings at the required locations on each layer of fabric, until all N layers of fabric are laid and all markings are completed.

[0068] This method efficiently and accurately prints markings on multiple layers of fabric by laying, fixing, and printing the fabric layer by layer. First, the length of the laying area is determined. Using the pattern in the garment cutting layout, the coordinates of the areas to be fixed are determined. The first layer of fabric is then fixed to the needle tip using a needle-punching device, ensuring that each layer covers the entire area during fixing. Finally, a printing device is used to precisely mark the required marking positions on each layer of fabric. Each layer of fabric undergoes the same laying, fixing, and marking process to avoid positional deviations between fabric layers and ensure printing accuracy. By fixing the fabric layer by layer and printing at the designated marking positions on each layer, the marking points are ensured to remain consistent across all layers, avoiding marking errors caused by interlayer misalignment and thus improving fabric processing precision. This method simplifies the marking operation for multi-layer fabrics, avoiding the tedious steps of processing each layer individually. It is suitable for large-scale fabric laying and processing needs, thereby significantly improving production efficiency. This method is applicable to various types of fabric marking, especially in situations requiring simultaneous marking of multiple layers of fabric, such as garment cutting and home textile fabric processing.

[0069] like Figure 10As shown, determining the length of the fabric laying area involves: using a garment cutting layout diagram or a manual garment cutting layout diagram to determine the required length of the fabric laying area. The layout diagram provides the specific position and size of each piece of fabric, thus enabling the determination of the marking printing position using garment cutting CAD software and the position of the through holes on the cutting and laying table. This allows for the completion of subsequent marking processes such as coding, cutting lines, key position lines, and topstitching in one go. By using a cutting layout diagram or a manual layout diagram, the length of the fabric laying area can be accurately determined, improving fabric utilization. The layout diagram precisely calculates the distribution position and size of the pieces, making the determination of the fabric laying length more scientific and reasonable, reducing unnecessary fabric waste during the laying process. The layout diagram can be adjusted according to different production needs or fabric types. Whether for large-scale production or small-batch customization, the length of the fabric laying area can be flexibly adjusted using the layout diagram to print various markings, adapting to different production modes.

[0070] The needle-punching fixing device includes a positioning needle, a positioning column, a cutting and laying table, a laying machine, a lifting device, a lifting pressure plate, an electric push rod, and a control system. The laying machine is installed on the top of the cutting and laying table, and multiple vertically installed electric push rods are installed below the cutting and laying table. The positioning needle is installed on the top of the electric push rod. The lifting device is installed on the cutting and laying table and drives the lifting pressure plate to rise and fall. The lifting pressure plate is located directly above the cutting and laying table. The control system is applied to the positioning needle, the cutting and laying table, the laying machine, the lifting device, the lifting pressure plate, and the electric push rod.

[0071] The steps of fixing the first layer of fabric using a needle-punching fixing device with the coordinate set as the fixed position include:

[0072] First, determine the coordinates of the positioning needle. The selected positioning needle extends out of the upper surface of the cutting and laying table. The fabric is laid on the top of the needle tip of the positioning needle exposed on the cutting and laying table by the fabric laying machine. The lifting device drives the lifting pressure plate to press down, pressing the printed fabric above the cutting and laying table. At this time, the needle tip of the positioning needle penetrates the positioning fabric.

[0073] The positioning pins play a crucial role in fixing the fabric. Driven by an electric push rod and positioning column, the pins extend to predetermined coordinate positions. The fabric spreading machine then lays the fabric on the cutting and spreading table. First, it moves along a slide rail to one end of the printer for fabric laying, or it can be done manually. After laying, the positioning pins support the fabric, and two workers assist in smoothing the fabric to ensure it is flat and securely fixed by the pins, guaranteeing accurate printing. After printing, the second layer of fabric is laid until the weight-bearing requirements of the pins or the required fabric laying are met. A lifting device then presses the fabric with a lifting pressure plate, and the pin tips penetrate the fabric for precise fixing. The entire operation is automated by a control system, ensuring the accuracy and stability of the fabric during multi-layer marking and cutting. The coordinate positioning and pinning of the pins ensure precise fixing of the fabric, preventing movement or positional deviation during cutting. The coordinated operation of the fabric spreading machine, lifting device, and control system achieves fully automated laying, pressing, and fixing, reducing manual intervention and improving work efficiency.

[0074] The printer can print custom content, and the printing process is controlled by a control system to print on the fabric according to the garment cutting and production requirements. One or more printers can be installed, assembled according to the cutting requirements.

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

[0076] In step S2, the coordinates required for fabric fixing are precisely set using a garment cutting layout diagram or a manual layout diagram. The fixing device is installed at these coordinate positions, ensuring that the fabric is firmly fixed during subsequent fabric laying and pressing processes. The precise guidance of the cutting layout diagram ensures that the cutting position of each layer of fabric is consistent with the height of the fixing points, preventing fabric shifting or misalignment.

[0077] In step S2, the method of fixing the first layer of fabric is to place an adhesive on the garment cutting and laying table to fix the first layer of fabric, and then continue to place an adhesive on the first layer of fabric to lay the second layer of fabric until the laying operation is completed.

[0078] This embodiment uses adhesives such as double-sided tape or removable tape to fix the fabric layer by layer. During the fabric laying process, the adhesives serve as temporary fixation, preventing the fabric from shifting or wrinkling during laying and subsequent processing. The adhesion between each layer of fabric ensures that the multiple layers can fit tightly together, avoiding errors during multi-layer cutting or marking. At the same time, the use of adhesives simplifies the operation steps and reduces the need for complex mechanical fixing equipment.

[0079] After the positioning needle tip penetrates the fabric, the operation step S2 is repeated until the positioning needle tip bears the required weight or reaches the required number of fabric layers. The lifting device then drives the lifting pressure plate to press down, pressing the printed fabric down to the top of the cutting and laying table. At this time, the positioning needle tip penetrates the laid fabric until the laying operation is completed.

[0080] This implementation method achieves precise fixation of multi-layered fabric by using positioning pins to puncture the fabric layer by layer. The needle tips of the positioning pins can penetrate the laid fabric layer by layer, playing a key role in the fixation process of multi-layered fabric. This ensures that each layer of fabric remains tightly fitted to the cutting and laying table. At the same time, the lifting device drives the lifting pressure plate to press each printed layer of fabric tightly, ensuring the stability and accuracy of the laying operation. The needle tips of the positioning pins not only fix the fabric but can also bear the weight of multiple layers of fabric until the required number of layers or the load-bearing requirement is reached.

[0081] The control system includes a garment cutting CAD layout system, an electric push rod control system, a printer control system, a fabric spreading machine control system, and a lifting pressure plate control system. The coordinate group that needs to be fixed is determined by the graphic in the garment cutting drawing. 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 by the fabric spreading machine.

[0082] This control system integrates multiple subsystems. It acquires graphic data through a garment cutting CAD layout system and uses an electric push rod control system to precisely control the extension position of the positioning needles. The fabric laying machine control system is responsible for automatically laying the fabric, ensuring that the fabric remains flat on the cutting and laying table. The lifting pressure plate control system presses the laid fabric to fix each layer of fabric, and the needle tips of the positioning needles penetrate the fabric to complete the fixation. In addition, the printer control system automatically prints on the fabric according to the cutting layout, ensuring the accuracy of subsequent processing.

[0083] The locations to be marked in step S3 include coding, knife edge, exposed line, point position, and custom identification symbol.

[0084] In step S3, the printer control system accurately prints the information to be marked onto the fabric. These markings include key locations such as coding, cutting lines, topstitching, and dots. Custom symbols and information can also be added. The printer control system will automatically mark all the necessary markings on the fabric according to the preset garment layout and symbol definition library, ensuring that the fabric can be processed according to the predetermined process in subsequent cutting, sewing and other processes.

[0085] like Figures 3-6 As shown, a needle-punching fixing device for fabric is provided, used to implement step S2 of claim 1 or 2 to fix the first layer of fabric, including a support mechanism 1, on which a printing mechanism 2 is provided, and further including:

[0086] Needle-punching fixing device 4 is mounted on the support mechanism 1. The needle-punching fixing device 4 is used to puncture the fabric printed by the printing mechanism 2 into the laid fabric.

[0087] The pressing mechanism 5 is mounted on the support mechanism 1. The pressing mechanism 5 is used to press the fabric so that the needle-punching fixing device 4 can fully insert the fabric.

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

[0089] The support mechanism 1 stabilizes each component. First, the coordinate group positions that need to be fixed are determined by the graphic in the garment cutting layout. The positioning needle of the selected needle fixing device extends out of the upper surface of the cutting and laying table. The fabric is laid on the top of the needle tip of the positioning needle on the cutting and laying table by manual labor or a laying machine. After the printer performs the printing operation, the lifting device drives the lifting pressure plate to press down, pressing the printed fabric onto the cutting and laying table. At this time, the needle tip of the needle fixing device penetrates the fabric.

[0090] Step S2, which determines the coordinate group that needs to be fixed on the fabric, and uses the positioning pins of the needle-punching fixing device to fix the first layer of fabric at the coordinate group as the fixed position, includes: first, determining the position of the coordinate group that needs to be fixed; then, manually or automatically placing the positioning pins and positioning needles of the needle-punching fixing device through the through-holes on the cutting and laying table onto the base frame; manually or using a laying machine, laying the fabric on the exposed needle tips of the needle-punching fixing device on the cutting and laying table for printing; and finally, using a lifting device to press down the lifting pressure plate to press the printed fabric onto the cutting and laying table, at which point the positioning pins of the needle-punching fixing device penetrate the fabric.

[0091] The needle-punching fixing device uses manual or automatic equipment to place the positioning column and positioning needle through the through hole above the cutting and laying table onto the base frame. Automatic equipment includes various types, and its purpose is to place the positioning column and positioning needle on the coordinate set that needs to be positioned without error.

[0092] The supporting mechanism 1 stabilizes all components, the printer 3 prints on the laid-out fabric at designated positions, and the pressing mechanism 5 applies pressure to the fabric through the lifting pressure plate 52, so that the positioning pin 42 completely penetrates the fabric, achieving precise positioning and marking of the fabric. The pressing mechanism 5 can be equipped with a pressure sensor, which, based on the thickness of the fabric fixed by the positioning pin, presses the fabric firmly and returns it. The above devices can effectively improve the accuracy of garment cutting and marking, and reduce errors caused by manual intervention. Especially in the positioning of multi-layered fabrics, the combined use of the needle-punching fixing device 4 and the pressing mechanism 5 ensures that each layer of fabric can be accurately positioned, greatly improving production efficiency and product quality. At the same time, by controlling the operation of the needle-punching fixing device and the printer, the labor intensity is significantly reduced.

[0093] Positioning pins 42 of different lengths and strengths can be selected according to the material and thickness of the fabric. The pushing force of the electric push rod 41 can also be adjusted to adapt to different operating needs. The lifting pressure plate 52 of the pressing mechanism 5 can be replaced with pressure plates of different shapes and sizes, pressing down the whole piece or pressing down in sections to adapt to different widths of fabric. In addition, the printhead of the printer 3 can also be selected in different models, using high-temperature disappearing ink, water-washable disappearing ink or other inks to meet the printing needs of multiple colors and precisions.

[0094] The support mechanism 1 includes a base frame 11, with multiple legs 12 fixed at the bottom of the base frame 11. A support rod 13 is fixedly installed at the top of the base frame 12, and a fixing frame 14 is fixed in the middle of the support rod 13. A cutting and laying table 15 is fixedly connected to the top of the support rod 13. The base frame 11 provides stable support for the overall structure, and the legs 12 ensure that the device is stable on the workbench. The support rod 13 provides longitudinal support and connects various functional components. The fixing frame 14 is used to stabilize the electric push rod 41, positioning column 44, and positioning pin 42, ensuring that they remain stable during operation. The cutting and laying table 15 serves as the base surface for fabric laying and processing, providing a stable operating platform for positioning needle punching and pressing. This support structure is simple and stable in design, effectively supporting and connecting various operating units, ensuring stability and reliability during operation. Through reasonable support and fixing design, not only is the overall stability of the equipment improved, but the installation and maintenance of each unit are also simplified.

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

[0096] The needle-punching fixing device 4 includes multiple electric push rods 41, positioning pins 44, and positioning needles 42. The fixed ends of the electric push rods 41 and positioning pins 44 are vertically fixed to the top of the base frame 11. The output ends of the electric push rods 41 and positioning pins 44 are fixedly connected to the positioning needles 42. The electric push rods 41 drive the positioning needles 42 to extend or retract according to the control signal. When the electric push rods 41 are retracted, the positioning needles 42 are lower than the cutting and laying table plane. When the electric push rods 41 are extended, the positioning needles 42 fix the fabric according to the positioning requirements of the laid fabric, achieving precise piercing of the parts of the fabric that need to be positioned. Through the coordinated work of multiple electric push rods 41, the movement of multiple positioning needles 42 can be controlled simultaneously, ensuring simultaneous positioning and penetration of multiple points of the fabric. Using electric push rods 41 to drive the positioning needles 42 can precisely control the piercing depth and position of the positioning needles, ensuring accurate positioning of the fabric. At the same time, through automated 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 post 44 is fixedly connected to a positioning pin 42. After determining the coordinate group that needs to be fixed, multiple positioning posts 44 and positioning pins 42 are placed manually or automatically to ensure simultaneous positioning and penetration of multiple points on the fabric, thereby completing the fabric positioning and preparing for printing.

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

[0098] The electric push rod 41 is located between the base frame 11 and the cutting and laying table 15. The electric push rod 41 is installed on the top of the base frame 11 and extends or retracts below the cutting and laying table 15. This installation method allows the positioning needle 42 to pass smoothly through the through hole of the cutting and laying table 15 during operation, accurately positioning and inserting into the fabric. By installing the electric push rod 41 between the base frame 11, the fixing frame 14 and the cutting and laying table 15, the positioning needle 42 can insert into the fabric more accurately and stably. This layout optimizes the overall structure of the equipment, reduces space occupation, and ensures the stability of the positioning needle 42 when inserting into the fabric.

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

[0100] The length of the positioning post 44 can be adjusted according to the thickness and material of the fabric to achieve the best insertion effect. The positioning needle 42 can be made of steel needles with different hardness and surface treatment to adapt to the characteristics of different fabrics. In addition, the number of positioning posts 44 and positioning needles 42 can be increased or decreased as needed to meet the positioning requirements of fabrics of different sizes.

[0101] The cutting and laying table 15 has multiple through holes 43, which are aligned with the electric push rod 41 on the same vertical axis. The design of the through holes 43 precisely corresponds to the position of the electric push rod 41, allowing the positioning needle 42 to pass smoothly through the through holes and pierce the fabric. Thus, when the electric push rod 41 extends, the positioning needle 42 extends from the upper surface of the cutting and laying table 15 through the through holes 43, achieving the marking and positioning of the fabric. By opening through holes 43 on the cutting and laying table 15, the positioning needle 42 can pass through the fabric without obstruction, improving the accuracy of fabric positioning and the working efficiency of the device. This design also reduces the potential damage to the fabric surface during operation, ensuring the quality of the fabric.

[0102] The distances between through holes, positioning pins, positioning posts, and electric push rods are determined according to the requirements of garment cutting and production. The purpose is to ensure that the graphics in the garment cutting layout can be precisely positioned, and to ensure that the cut pieces are error-free and all printed content is error-free.

[0103] The diameter and number of through holes 43 can be adjusted according to the needs of different fabrics to adapt to different operating requirements. More wear-resistant materials can be used to make the cutting and laying 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 pins and increase the applicability of the device.

[0104] A slide rail is installed on the long side of the cutting and laying table 15. The fabric laying machine 40 and the printer 3 slide on the cutting and laying table 15 via the slide rail. The slide rail is installed on the long side of the cutting and laying table 15 to guide the fabric laying machine 40 and the inkjet printer 3 to move along different directions of the slide rail. The slide rail setting allows the fabric laying machine 40 to lay the fabric smoothly and 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 fabric laying and printing can be achieved. The slide rail setting simplifies the movement control of the fabric laying machine 40 and the inkjet printer 3, making the fabric laying and printing process smoother and more efficient. This design can shorten the fabric laying and printing time, improve the overall production efficiency, and reduce the need for manual operation. At the same time, the application of the slide rail ensures the accuracy of fabric laying and printing.

[0105] The length and position of the slide rail can be adjusted according to the size of the table. Multiple slide rails can also be installed to increase the stability and flexibility of the equipment. If it is necessary to increase the smoothness of movement, rollers or sliders can be added to the slide rail to reduce the friction of the equipment. In addition, the service life of the equipment can be increased 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 the extended state, the portion of the positioning pin 42 extending out of the cutting and laying table 15 is the first gap, and the gap between the laying machine or printing mechanism 2 and the upper surface of the cutting and laying table 15 is the second gap. The first gap is smaller than the second gap.

[0107] To ensure that the fabric, after being pierced by the positioning pin 42, does not interfere with the operating space of the fabric laying machine 2 and the printer 3, this spacing design ensures that the fabric laying, printing and positioning actions are independent and undisturbed. The reasonable spacing design ensures the coordinated work between various operating modules, so that the fabric laying, printing and positioning actions can be carried out continuously and smoothly. By maintaining the extension distance of the positioning pin 42 and the working distance of the equipment, mutual interference between the equipment is avoided, and the overall work efficiency and equipment safety are improved.

[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 pin 42 is always kept in the optimal state. In addition, the spacing can also be adjusted by 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 pressure plate 52 is fixed at the output end. The lifting pressure plate 52 has multiple limiting holes 53. The limiting holes 53 and the through holes 43 are on the same vertical axis. The lifting device 51 drives the lifting pressure plate 52 to move in the vertical direction. The limiting holes 53 on the lifting pressure plate 52 are designed to correspond to the through holes 43. When the lifting device 51 drives the lifting pressure plate 52 to press down, the limiting holes 53 can guide the positioning needle 42 to accurately pierce the fabric. This structure ensures that the path of the positioning needle 42 is accurate during pressing, making the positioning of the fabric more reliable. Through the design of the lifting pressure plate 52, the fabric can be effectively pressed into place, and the positioning needle 42 can be penetrated and positioned. The alignment of the limiting holes 53 and the through holes 43 provides precise guidance, avoids the positioning needle 42 from deviating or tilting, and greatly improves the positioning accuracy and repeatability. The shape and size of the lifting pressure plate 52 can be adjusted according to the actual width of the fabric, and the layout of the limiting hole 53 can also be optimized as needed. The lifting device 51 can be driven by different methods, 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 fabric.

[0110] The pressing mechanism 5 includes a lifting device 51 fixed on the cutting and laying table 15. The lifting device 51 is vertically downward. A lifting pressure plate 52 is fixed at the output end of the lifting device 51. A plurality of limiting holes 53 are provided on the lifting pressure plate 52. The limiting holes 53 and the through holes 43 are on the same vertical axis.

[0111] The cutting and laying table is an operating platform for laying fabric, with the top used to place the fabric. The surface of the cutting and laying table is designed with through holes 43, allowing fixing mechanisms such as positioning pins or other needle-punching devices to be fixed in the required positions, piercing the fabric for fixation.

[0112] Printing mechanisms 2 and printers 3 are installed on both sides of the cutting and laying table 15. These printing mechanisms are used to print various markings on the fabric, including the markings for the cutting edge, topstitching, and dots mentioned in step S3. These markings provide guidance to the operator during subsequent cutting and sewing processes, ensuring that the fabric is accurately cut and processed.

[0113] The lifting device 51 is vertically installed above the cutting and laying table 15, and its output end is connected to the lifting pressure plate 52. The lifting device controls the downward or upward operation of the lifting pressure plate through vertical movement, thereby pressing the fabric onto the cutting table. During the pressing process, the fabric is fixed by adhesive or needle punching.

[0114] In summary, a method for printing marking points on garment fabric is a garment cutting and production process. The process involves first fixing the fabric, then printing, then pressing the fabric down until the fabric laying is completed, and finally cutting.

[0115] Example 2, which differs from Example 1:

[0116] like Figure 2 As shown, a method for printing marking points on garment fabric is also provided, used to print the positions to be marked on N pieces of fabric. The marking point printing method includes:

[0117] S1. Determine the length of the fabric laying area;

[0118] S2. Determine the coordinate set that needs to be fixed on the fabric, and use a needle-punching fixing device to fix the first layer of fabric at the coordinate set as the fixed position.

[0119] S3. Print the markings for the first layer of fabric.

[0120] S4. Fix the second layer of fabric on the first layer of fabric, and print the marking positions on the second layer of fabric.

[0121] S5. Repeat step S4 to lay and fix the remaining N-2 sheets of fabric and print the markings as needed. Continue until the fabric laying is complete.

[0122] like Figures 8-9 As shown, the steps of fixing the coordinates that need to be fixed by using the cutting and laying table and the multiple through holes opened on the cutting and laying table and the lifting device also include: determining the coordinates of the through holes by the graphics in the garment cutting layout diagram, placing multiple positioning pins 44 with positioning pins 42 fixed on the top of the through holes 43 where the coordinates are determined, laying the first layer of fabric on the top of the positioning pins 42, printing the printer 3, laying the second layer of fabric after the printing is completed, and printing until the cutting requirements or the load-bearing range of the positioning pins are met;

[0123] The lifting device drives the lifting pressure 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. Repeat the above operation until the laying operation is completed.

[0124] The fabric is positioned and fixed using through holes 43, positioning posts 44, and positioning pins 42. First, the coordinate sets of the positions to be fixed are determined according to the pattern in the garment cutting layout. Then, positioning posts 44 and positioning pins 42 are placed on the through holes 43 to complete the fixation. This ensures the consistency of the marked positions on each layer of fabric, preventing the fabric from shifting during cutting or processing. The lifting pressure plate further presses the fabric firmly onto the platform, ensuring the fabric is flat and stable.

[0125] By determining the coordinates of the through holes using the graphics in the garment layout diagram and inserting positioning posts and steel pins at the corresponding positions, the fixing points of each layer of fabric can be ensured to be accurate, which helps to improve cutting accuracy and fabric utilization. The steel pins of the positioning posts penetrate the fabric directly and fix it firmly to the cutting and laying table, avoiding errors and defects caused by fabric movement during the cutting process, and ensuring the accuracy and quality of the finished product. This fixing device, together with the automatic operation of the lifting device and pressure plate, reduces manual operation steps and greatly improves production efficiency, making it particularly suitable for large-scale industrial production.

[0126] Example 3, which differs from Example 1:

[0127] The first layer of fabric is laid and fixed in the laying area. Alternatively, adhesive can be placed on the garment cutting and laying table to fix the first layer of fabric.

[0128] Printing is performed through printer 3 of printing unit 2;

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

[0130] By bonding the fabric together, we prevent it from shifting or tilting, thus ensuring the accuracy of subsequent cutting. Repeat the above steps until the fabric laying is complete.

[0131] The choice of adhesive material is determined by the requirements of garment cutting.

[0132] Preferably, the electric actuator is model IP60WR.

[0133] Preferably, the model of the fabric spreading machine is ZC-DCP-210-YC.

[0134] Preferably, the printer model is XF-5228, and the ink is selected according to the needs of garment production.
