Description

Technical Field

[0001] The utility model belongs to the field of clothing machinery, and particularly relates to a cloth numbering machine. Background Art

[0002] Because each roll of cloth will have some color variation from another, ensuring that all parts of each garment are the same requires that the same roll of cloth be used for each garment. During the production process, to improve efficiency, the fabric-cutting process involves laying out dozens or even more rolls of cloth at once for cutting, and then stitching and sewing the various garment parts on the assembly line. Therefore, to ensure that the same roll of cloth is used for each garment, all cut garment parts must be numbered and marked to avoid confusion.

[0003] Current automatic fabric marking machines rely on needles to prick a layer of fabric. An old-fashioned manual marking machine is then embedded within the machine to mark the fabric. An air pump then blows away the remaining layer before moving on to the next. The current problem is that the needle length must be adjusted to precisely reveal only one layer of fabric, making this adjustment difficult and requiring repeated adjustments for each layer. Furthermore, it's not always possible to reveal only one layer of fabric within the same stack. Consequently, existing technology suffers from missed numbers and low marking efficiency.

DETAILED DESCRIPTION

[0032] The technical solution is further described below with reference to the accompanying drawings and specific embodiments to facilitate understanding of the content of the present utility model.

[0033] The core idea of ​​this utility model is to create a staggered end surface at one end of the fabric by causing the fabric to shift layers during the bending process. The staggered end surface can be used to turn over and print layer by layer, or the exposed area of ​​the staggered end surface can be used for direct printing. The specific application methods are as follows:

[0034] Example 1

[0035] like Figure 1 As shown, a cloth marking machine includes: a frame s1, a roller s2 fixed to the frame s1 through a bearing as a curved surface support component, a pressure plate component S3 fixed to the frame s1 for fixing one end of the cloth 3, a staggered pressing component s4 fixed to the frame s1 for fixing the staggered end surface 30 of the other end of the cloth 3, a printing wheel component s5 fixed to the top of the frame s1 and used for turning over and printing the cloth 3, and a cloth pressing wheel component s6 fixed to the top of the frame s1 and used for fixing the cloth 3.

[0036] like Figure 2As shown, the staggered lamination assembly s4 comprises a primary platen drive rod s41 fixed to the frame s1, a secondary platen drive rod s42 connected to the primary platen drive rod s41 via a servo motor, and a platen s43 connected to the secondary platen drive rod s42. The platen s43 comprises a cylindrical surface adapted to the fabric. The main body of the platen s43 is made of metal or engineering plastic, and its front end has a flexible, elastic end s4301 to facilitate the print wheel assembly s5 overcoming the pressure of the platen on the fabric and flipping the surface layer of the fabric. The servo motor driving the primary platen drive rod s41 is located within the frame s1.

[0037] like Figure 3 As shown, the printing wheel assembly s5 includes a group of slide rail fixing seats s51 fixed to the frame s1, a slide rail s52 fixed between the two slide rail fixing seats s51, a driving slider s53 slidably fixed to the slide rail s52, a cylinder s54 fixed under the driving slider s53, and a numbering gear s55 fixed to the driving end of the cylinder s54; the driving slider s53 includes a slider cooperating with the slide rail s52 and a servo motor for driving, and the driving transmission method is a gear rack pair or a synchronous belt.

[0038] The cloth pressing wheel assembly s6 is a two-stage mechanical arm structure, and both stages of the mechanical arms are driven by a disc-type direct-drive servo motor.

[0039] like Figure 4 As shown, the numbering gear s55 has multiple tooth structures, each of which includes a cloth-turning tooth tip s551 located at the tip of one side and a printing tooth surface s552 for printing on the fabric surface. The cloth-turning tooth tip s551 has a comb-like structure that lifts the top layer of fabric. The printing tooth surface s552 is provided with a specific shape pattern for printing numbers on the fabric surface. Multiple numbering gears s55 are typically used in groups to achieve a larger coding range. The numbering gear s55 can print numbers on the fabric surface by pressing or sliding. The operation of pressing down to stamp is equivalent to the operation of a manual seal. From top to bottom, the printing tooth surface s552 is pushed by the cylinder s54 to contact the surface of the cloth, thereby completing the numbering; the operation method of sliding numbering is: first, the printing tooth surface s552 contacts the end of the top layer of cloth, and with the rotation of the printing tooth surface s552 and the movement of the driving slider s53 on the slide rail s52, the top layer of cloth is turned over. At the same time, the printing tooth surface s552 is controlled by controlling the cylinder s54 to contact the surface of the next layer of cloth, and then the printing tooth surface s552 is driven by the driving slider s53 to slide forward on the surface of the next layer of cloth, and the printing label is realized on the surface of the next layer of cloth during the sliding process. The coding form of the label is preferably a barcode to facilitate printing the label on the cloth surface in a sliding manner.

[0040] The working process of the cloth marking machine described in this embodiment is as follows Figure 1 and Figure 5-8 The specific implementation steps are as follows:

[0041] Step 1: If Figure 1 As shown, one end of the cloth 3 is fixed to the roller s2 by the pressing plate assembly S3, and then the cloth 3 is placed in an upward arc along the outer circumference of the roller s2.

[0042] The staggered layer lamination assembly s4, the printing wheel assembly s5, and the cloth pressing wheel assembly s6 are all in a standby state.

[0043] Step 2: As shown in step 5, the control power supply of the cloth pressing wheel assembly s6 is activated, and the servo motors at each level drive the cloth pressing wheel assembly s6 to extend downward, and then the cloth pressing wheel at the front end of the cloth pressing wheel assembly s6 presses against the fixed end of the cloth 3. The staggered lamination assembly s4 and the printing wheel assembly s5 are both in a standby state.

[0044] Step 3: If Figure 6 As shown, driven by servo motors at various levels, the mechanical arm of the cloth pressing wheel assembly s6 drives the cloth pressing wheel to roll upward along the surface of the cloth 3 until the upper end of the cloth 3 stops to one side of the free end of the cloth, and the cloth pressing wheel rolls from bottom to top to fully press the layers of cloth 3 against the roller s2. At the same time, each layer of cloth is fully extended to form a staggered end face 30 at the free end of the cloth. The end face of each layer of cloth is staggered to facilitate the subsequent turning over of the cloth and numbering layer by layer by the numbering gear s55.

[0045] The staggered layer pressing assembly s4 extends its mechanical arm and presses down on the staggered layer end surface 30 of the cloth 3; the printing wheel assembly s5 is in a standby state.

[0046] Step 4: If Figure 7 As shown, driven by the servo motors at various levels, the mechanical arm of the cloth pressing wheel assembly s6 drives the cloth pressing wheel to move upward and disengage from the cloth 3. The printing wheel assembly s5 is activated to cause the numbering gear s55 to contact the end surface of the first layer of cloth above the staggered end surface 30. As the printing tooth surface s552 rotates and the driving slider s53 moves on the slide rail s52, the top layer of cloth is opened. At the same time, the printing tooth surface s552 is controlled by the control cylinder s54 to contact the surface of the next layer of cloth. Then, the driving slider s53 drives the printing tooth surface s552 to slide forward on the surface of the next layer of cloth. During the sliding process, a label is printed on the surface of the next layer of cloth. The label encoding form is preferably a barcode to facilitate printing the label on the cloth surface in a sliding manner.

[0047] Step 5: Figure 8As shown, when the printing number is completed, the driving slider s53 moves outward on the slide rail s52. During the movement, the cloth turning tooth tip s551 drives the top layer of cloth 301 to turn outward, thereby completing the printing of one layer of cloth and the lifting and turning of the upper layer of cloth.

[0048] Repeat steps 1-5 above until all the fabrics are printed layer by layer.

[0049] The drum is a horizontally placed cylinder in appearance.

[0050] First, a stack of fabric is secured above a drum. Using the centripetal force generated by the drum's rotation, the fabric is gradually spread out along the drum's axis. This spreading process is like the even shuffling of playing cards by a shuffler, or like the stamping of a contract—a process that is both neat and standardized. The spacing between each layer of fabric is meticulously designed to be equidistant, ensuring precision in subsequent processing.

[0051] Once the fabric is laid out, a row of specially designed print wheels comes into play. These wheels, dipped in ink, gently roll over each layer of fabric, leaving a unique mark. By adjusting the distance between the print wheels and the fabric, we ensure that each layer of fabric is uniquely marked, preventing confusion or duplication.

[0052] These print wheels are designed with both the printing and fabric flipping processes in mind. Their teeth are made of rubber to increase friction with the fabric, ensuring the wheel grips the fabric firmly and leaves a clear mark. Furthermore, the print wheel is hollow and filled with ink, ensuring a clear and long-lasting mark with each roll.

[0053] This utility model has broad application prospects. It can not only be used for marking and identifying fabrics, but can also be further expanded to multiple fields such as textile production and clothing manufacturing. By optimizing the design of the roller and the working method of the printing wheel, we can further improve production efficiency and product quality, bringing greater value to related industries.

[0054] Another innovative numbering method uses binary 0 and 1 instead of numbers to distinguish numbers. This method is not only highly accurate, but also provides clear and easy-to-read marks during the fabric numbering process.

[0055] First, we set up a set of print wheels. The number of these wheels can be adjusted as needed. For example, we could use 10 print wheels, with fine print wheel marking areas at both ends for easy identification later. These fine print wheels also assist in gripping the fabric. These print wheels will be used to leave marks on the fabric for numbering purposes.

[0056] On the first layer of fabric, the first print wheel from the right grabs the fabric and leaves an imprint. At this point, none of the nine print wheels on the left touch the fabric. Next, on the second layer, the second print wheel from the right grabs the fabric and leaves an imprint, while the first print wheel remains idle, and the eight print wheels on the left also remain idle. On the third layer, the first and second print wheels from the right leave two imprints, and the eight print wheels on the left remain idle, making no contact with the fabric! On the fourth layer, the third print wheel from the right touches the fabric, the first and second print wheels from the right remain idle, and the seven print wheels on the left remain idle!

[0057] And so on, using the binary method of counting! (0000000001=1, 0000000010=2, 0000000011=3, 0000000100=4, 0000000101=5, 0000000110=6, 0000000111=7 binary counting method).

[0058] The core of this numbering method lies in the use of binary counting. Specifically, the state of each gear tooth can be considered a binary bit, where 0 indicates no contact with the fabric, and 1 indicates contact and leaving an imprint. This allows us to determine the number of layers of fabric by reading the sequence of gear tooth states. For example, when the gear tooth state sequence, counting from the right, is 0000000001, it represents the first layer of fabric; when the state sequence is 0000000010, it represents the second layer of fabric, and so on.

[0059] To make it easier to identify binary 1s, or the teeth on a gear, we can use different symbols. For example, we can use shapes like a moon, a triangle, a circle, or a square, using one for every two adjacent gear teeth. This way, when we examine the markings on fabric, we can quickly determine the number of layers by identifying these shapes.

[0060] In practice, we also need to consider how to secure the fabric in place so that the print wheel can accurately grasp and mark it. To achieve this, a large roller can be used to secure the fabric. First, the centripetal force generated by the roller's rotation spreads the fabric flat on the roller. Then, the gears and the roller's speed are adjusted to ensure that each layer of fabric to be grasped is at the very top of the roller. Once the print wheel grasps the fabric, gravity pulls it back, preventing it from interfering with subsequent grasping and marking.

[0061] And it’s convenient to only grab one!

[0062] It's important to note that because the fabric is soft, only when the print wheel actually touches and grabs the fabric can it leave an imprint. Therefore, in addition to the print wheels on both sides of the top, which grab each layer of fabric and leave an imprint to mark the boundary, the middle print wheel teeth, the rightmost tooth, grabs every other layer of fabric and leaves an imprint. The second gear from the right needs to grab two layers in a row, then leave two layers, then grab two layers in a row again! The third gear from the right needs to grab four layers in a row, leave four layers in a row, then grab four layers in a row again. The fourth gear from the right needs to grab eight layers in a row, then leave eight layers in a row, then grab eight layers in a row again, and so on.

[0063] In addition, to ensure that the gears can accurately grab the fabric and leave an imprint, the height of the shaft needs to be adjusted according to the gear speed and the characteristics of the fabric.

[0064] The solution is to adjust the shaft height starting with the second gear from the right. Starting at the second gear from the right, the shaft rotates at a constant speed of one layer per grab. However, the shaft height increases or decreases every certain number of revolutions (the number of layers of fabric being grabbed) based on the speed of the first gear from the right or the gears at the ends of the top. Regardless of whether the shaft is high or low, the fabric remains in rotation.

[0065] The gears are used to flip the fabric and stamp the number in one go. The gears contain ink, and when they grab the fabric, they make contact, leaving behind a dot of ink. Different layers of fabric will have gears in different positions grabbing the fabric, leaving different numbers and positions of ink dots. These are the binary numbers that stamp the number and flip the fabric in one go! My gears are arranged in a horizontal row, with at least 10 gears (10 gears can stamp numbers up to 1000, and more gears are needed). For the first layer of fabric, only the first gear grabs the fabric. For the second layer, only the second gear grabs the fabric. The third gear... and so on, as shown in the table below:

[0066]

[0067] To prevent the gears from lacking enough grip to prevent the cloth from being caught, you can add two additional gears on either side to create a continuous grip, similar to the boundaries. To make it easier to identify, you can also change the ink dots into different shapes, such as triangles, moons, or circles. This way, different gears gripping the cloth leave different ink dots, thus facilitating both gripping and marking.

[0068] In summary, this binary-based marking method is highly accurate and reliable, providing clear, easy-to-read markings during fabric marking. By properly designing the gears and adjusting the shaft height, we can ensure that the gears accurately grasp the fabric and leave their mark, resulting in fast and accurate marking.

[0069] The design of the roller needs to take into account its size, material and the way it presses the cloth to ensure that it can effectively press the cloth and prevent multiple layers of cloth from being grabbed at the same time.

[0070] First, the roller's diameter should be smaller than the difference in length between the two layers of fabric, similar to the difference in length between each card when playing cards are laid out diagonally. This design ensures that the roller can accurately control the thickness of the fabric when pressing it, preventing multiple layers of fabric from overlapping.

[0071] Secondly, the roller needs to be equipped with a sensor to monitor changes in its height. When the roller lowers, the sensor sends a signal, instructing the gears to begin grabbing the fabric. The coordinated operation of the roller and gears is crucial during this process. Once the roller presses down on the fabric, the gears must precisely grasp a single layer and quickly disengage to avoid damaging the fabric.

[0072] As the drum rotates, it moves with it, while the gear remains stationary. When the drum drops to a preset height (the thickness of one layer of fabric), the gear rotates again to pick up the next layer. This cycle ensures that only one layer of fabric is picked up at a time, improving production efficiency and product quality.

[0073] Furthermore, to further improve fabric gripping accuracy, we can install sensors similar to those used in banknote counters on the rollers. If the sensors detect that two sheets of fabric have been gripped or one sheet has been missed, they immediately sound an alarm, stopping the machine and alerting the operator to address the issue. This feature effectively prevents production problems caused by misoperation or equipment failure.

[0074] When the fabric is first fixed, the roller rolls and uses centripetal force to spread the fabric. During this process, the roller can roll over the fabric several times, and through computer statistics, the height difference that appears the most is extracted, which is the actual thickness of the fabric. If the number of times this height appears is not more than 99% or even 100%, it means that the fabric is not flat, and an alarm sound may be prompted and manual intervention may be required. When the test is completed, theoretically, the height difference should be fixed to the thickness of the fabric, and the roller will lower the height from highest to lowest according to the thickness of the fabric, and the number of times the fixed reduction value appears is 100%. (This process is equivalent to the counting process), and then the gears start to grab the fabric and number it. (The roller presses the fabric, the gears grab the fabric, the roller rotates, the roller reduces the height difference, and the gears grab the fabric again)

[0075] The rollers can also be changed to a vertical row similar to ballpoint pens according to actual conditions, ensuring that they are strong enough to press the cloth and small enough (the gap between the cloths, that is, the length difference mentioned above, is small).

[0076] The roller below rotates to ensure that the cloth to be grabbed is turned by the gear and can be turned downward under the action of gravity without affecting subsequent operations. Therefore, the roller, the roller (or the downward pressure probe), and the gear must move in coordination.

[0077] During the process of securing and unwinding the fabric, we also need to take some measures to ensure its flatness and stability. For example, to secure the fabric to the drum, you can use a parallelogram-shaped clamp (flexible enough to be fixed in an arc concentric with the drum). After securing, rotate it to remove static electricity and break free from adhesion. The fabric of sufficient length will then naturally spread evenly on the drum, taking advantage of the drum's curvature. For shorter fabrics, the parallelogram clamp can be clamped and then pushed (or electrically operated) to use external force to evenly spread the fabric on the drum.

[0078] Finally, the coordinated movement between the roller, roller (or downward probe) and gear is also the key to achieving precise grasping. These components need to move in coordination according to preset programs and parameters to ensure that the fabric can remain stable during the grasping process.

[0079] In summary, by optimizing the design of key components such as rollers, rollers, and gears, and introducing technologies such as sensors and inductors, we can achieve precise fabric gripping and stable operation. This not only helps improve production efficiency and quality, but also reduces production costs and waste.

[0080] Example 2

[0081] like Figure 9 As shown, a fabric staggered mechanism comprises: a curved surface support component 1 for supporting the fabric 3 and a staggered layer pressing component 2 for forming a staggered end surface 30 by pressing the fabric 3;

[0082] The curved surface support assembly 1 includes an arc cylinder;

[0083] The staggered lamination assembly 2 includes a cylindrical surface adapted to the fabric.

[0084] The curved surface support assembly 1 includes: a curved surface support plate 11 having a concave cylindrical surface, and a driving assembly 12 connected to the curved surface support plate 11 .

[0085] like Figure 10 As shown, the curved support plate 11 includes: a hard support segment 111 having one end connected to the execution end of the drive assembly 12, and a flexible support segment 112 connected to the other end of the hard support segment 111; the curvature of the flexible support segment 112 is greater than the curvature of the hard support segment 111; the flexible support segment 112 is made of elastic material.

[0086] The staggered lamination assembly 2 includes: a driver 21 fixed to an external stationary structure, a rotating bracket 22 connected to the execution end of the driver 21, a rotating pressure block 23 with a bearing fixed to the end of the rotating bracket 22 and having an external convex cylindrical surface, and a rotating driver 24 fixed to the rotating bracket 22 and transmission connected to the rotating pressure block 23.

[0087] The rotating pressing block 23 includes a vibrator and / or air holes. The vibrator is installed inside the rotating pressing block 23 and can transmit vibrations to the fabric 3 to promote fabric layering, effectively solving the problem of adhesion between fabrics and preventing individual layers from being missed. The air holes are evenly distributed on the working surface of the rotating pressing block and can be connected to a vacuum pump or air pump through valve switching to achieve the effect of adsorption or blowing the fabric 2 into layers.

[0088] During the downward pressing process of the rotating pressing block 23, the air holes are connected to the air pump through an air path, and the air holes evenly distributed on the surface of the rotating pressing block 23 blow out air to avoid wrinkles in the process of pressing the fabric.

[0089] After the rotating pressing block 23 completes its downward pressing process and contacts the fabric 3, the air holes are connected to a vacuum pump via an air path. A vacuum is created near the air holes evenly distributed on the surface of the rotating pressing block 23, sucking the fabric 3 and adhering to the surface of the rotating pressing block 23. Simultaneously, the rotating pressing block 23 rotates, driving the fabric 3 layer by layer to create interlayer displacement and form the staggered end face 30. Furthermore, when used in conjunction with a vibrator, the interlayer displacement effect on the fabric can be further enhanced, resulting in greater layer displacement, a greater exposed width of each layer of fabric on the staggered end face 30, and a larger print area, which is beneficial for improving the print quality of the mark.

[0090] The fabric staggered mechanism disclosed in the present invention can form a staggered end surface 30 on one side of the multi-layer stacked fabrics, and each layer forms an exposed area of ​​a certain width on the staggered end surface 30, so that each layer of fabric can be numbered on the staggered end surface 30 at one time, thereby greatly improving the numbering efficiency. Compared with the existing manual numbering machine and mechanical method of turning over each layer of fabric layer by layer for numbering, the efficiency is significantly improved, and the omission rate is also significantly reduced.

[0091] Example 3

[0092] Based on the same utility model concept, the utility model also provides a cloth marking machine.

[0093] like Figure 11 As shown, the marking machine includes:

[0094] A carrying platform 4, which is fixed to an external stationary structure (usually a frame or box-type rack) and is used to place the stacked fabrics 3;

[0096] And a fabric staggered mechanism as described in Example 1, which is indirectly fixed to the press plate platform 4 through a mechanical structure (not shown in the figure), and the curved support component 1 and the staggered pressing component 2 press and fix the other end of the fabric 3 to form a staggered end surface 30 at the end of the fabric 3;

[0098] The marking machine also includes a marking assembly 7, which is fixed to the pressure plate platform 4 and disposed outside the staggered end surface 30. The marking assembly 7 includes: an arcuate guide rail 71 fixed to the support platform 4, a marking machine bracket 72 slidably fixed to the arcuate guide rail 71, a marking machine 73 fixed to one end of the marking machine bracket 72 facing the curved support plate 11, a circumferential drive 74 fixed to the other end of the marking machine bracket 72, and an arcuate rack 75 fixed to the arcuate guide rail 71 and parallel to each other; the shape of the arcuate guide rail 71 is adapted to the concave cylindrical surface of the curved support plate 11; the circumferential drive 74 engages with the arcuate rack 75 via a gear to adjust the position of the marking machine 73.

[0099] The marking machine 73 includes at least one of an inkjet marking device, a laser marking device, a hot stamping device, and an offset printing device.

[0100] like Figure 12As shown, at the staggered end surface 30 of the fabric 3, exposed portions are formed between each layer of fabric. The front end of the curved support plate 11 is a fork-shaped structure, with a printing window formed in the middle. Printing areas are formed in the staggered exposed portions of each layer of fabric. For example, a first printing area 301 is provided on the exposed portion of the first layer of fabric, a second printing area 302 is provided on the exposed portion of the second layer of fabric, a third printing area 303 is provided on the exposed portion of the third layer of fabric, and a fourth printing area 304 is provided on the exposed portion of the fourth layer of fabric. Similarly, each layer of fabric has a printing area. Different marking numbers can be printed on each layer, or the same marking number can be printed on a predetermined number of layers, as needed. Specifically, the marking numbers can be barcodes, digital codes, or simpler color codes to distinguish between batches of fabric with color differences.

[0101] The working process of an example of the cloth marking machine of the utility model is as follows:

[0102] Step 1. First, place multiple stacked fabric slices on the carrying platform 4;

[0103] Step 2. Select a positioning baffle 62 of appropriate shape and install it on the driving end of the positioning drive assembly 61;

[0104] Step 3. Adjust the position of the cloth positioning assembly 6 on the supporting platform 4 so that the end surface of the cloth to be numbered is located above the curved support assembly 1, and turn on the power of the electromagnetic adsorption to fix the position of the positioning drive assembly 61;

[0105] Step 4. Turn on the power of the pressing plate driver 51, and the actuator of the pressing plate driver 51 pushes the pressing plate 52 downward to press and fix the fabric;

[0106] Step 5. Turn on the power of the drive assembly 12. The actuator of the drive assembly 12 pushes the curved support plate 11 through the through hole 41 of the carrying platform 4. The support plate 11 continues to move upward until the lowest end of the hard support segment 111 is flush with the carrying platform 4.

[0107] Step 6. Turn on the power supply of the air pump of the rotating pressing block 23, and the air holes on the surface of the rotating pressing block 23 will discharge air; turn on the power supply of the driver 21 to push the rotating bracket 22 downward, and during the downward movement, the air holes will blow on the surface of the fabric to prevent wrinkles and curling;

[0108] Step 7. When the rotating pressing block 23 contacts the fabric, the power supply to the driver 21 is cut off to stop further compaction of the fabric. In another embodiment, the air pores are blocked by the fabric, the air pressure in the air path increases, and the air pressure sensor generates an electrical signal to the controller or relay to cut off the power supply to the driver 21.

[0109] Step 8. Turn on the power of the rotary driver 24, which drives the rotary pressing block 23 to rotate slowly outward through the gears. At the same time, the vibration motor in the rotary pressing block 23 is activated to prevent adhesion between the fabrics. At the same time, the power of the driver 21 is continued to be turned on to further compact the fabrics, forming a staggered end surface 30 at the end of the fabrics.

[0110] Step 9. Turn on the power of the circumferential driver 74 and align the marking machine 73 with the marking area of ​​each layer of fabric to mark the fabric.

[0111] In another embodiment, when the fabric layer is thicker or the displacement between each layer of the staggered end surface 30 is desired to be larger, the operation is different from the above embodiment in steps 4 and 8, which are specifically described as follows:

[0112] Step 4 '. Turn on the power of the pressure plate driver 51. The actuator of the pressure plate driver 51 pushes the pressure plate 52 downward to slightly fix the fabric with a pressure of no more than 5N. The specific pressure needs to be determined based on the friction coefficient of the fabric. The appropriate pressure can keep the fabric moderately tensile during the subsequent staggered movement, but it cannot hinder the staggered movement.

[0113] Step 8 '. Extend the power-on time of the rotary driver 24 and the vibration motor to drive a greater staggered displacement between the fabrics.

[0114] The above implementation process is merely an example. The specific steps and operating parameters can be adjusted based on the fabric characteristics and numbering requirements. Operations can be performed manually, using power control, or automatically, using program control. Given the widespread application of automation in various aspects of industry and life, numerous publicly available and commercially available solutions exist, which will not be elaborated upon here.

[0115] The accompanying drawings of this embodiment illustrate only the core components of a fabric marking machine. Detailed descriptions of the known and necessary prior art components, such as the machine frame, control circuit, power supply, air supply, air circuit control, and program control, are omitted. Essential technical details not described in this embodiment are prior art and therefore will not be fully detailed or explained.

[0116] This new invention utilizes the staggered ends of the fabric to form a printing area, simplifying the traditional method of numbering the fabric layer by layer, greatly improving numbering efficiency. The mechanical structure bends the fabric to achieve staggered ends, solving the problem of missed operations or multiple layers of fabric being opened at once when using gears to open each layer, significantly reducing the missed numbering rate. By marking the edge of each layer of fabric, this new invention facilitates the re-inspection of fabric batches and improves work efficiency. It solves the problems of missed numbers and low numbering efficiency in the existing technology.

[0117] Example 4

[0118] Based on the same utility model concept, the utility model also provides a cloth marking method, using a cloth marking machine as described in Example 2, such as Figure 13 As shown, the method includes the following steps:

[0119] Placing the stacked multiple layers of fabric on the carrying platform, and placing the end of the fabric to be numbered on top of the curved support assembly;

[0120] The pressing plate assembly presses and fixes the other end of the cloth;

[0121] The staggered layer pressing assembly presses and fixes the fabric and forms staggered layer end faces at the ends of the fabric;

[0122] The marking component is started to mark the staggered end surface.

[0123] This new invention utilizes the staggered ends of the fabric to form a printing area, simplifying the traditional method of numbering the fabric layer by layer, greatly improving numbering efficiency. The mechanical structure bends the fabric to achieve staggered ends, solving the problem of missed operations or multiple layers of fabric being opened at once when using gears to open each layer, significantly reducing the missed numbering rate. By marking the edge of each layer of fabric, this new invention facilitates the re-inspection of fabric batches and improves work efficiency. It solves the problems of missed numbers and low numbering efficiency in the existing technology.

[0124] Furthermore, the marking machine 73 moves along the arc-shaped guide rail 71 to mark the staggered end surfaces 30 of the cloth 3 layer by layer.
