[0002] Because each roll of cloth has a color difference with another roll, in order to ensure that each part of each garment has no color difference, it is necessary to ensure that the same roll of cloth is used for the same garment. In the production process, in order to improve efficiency, the cloth cutting process lays out more than a dozen rolls of cloth at a time for cutting, and then sews the various garment parts on the assembly line; therefore, to ensure that the same roll of cloth is used for the same garment, all the cut garment parts must be numbered and marked to avoid confusion.

DETAILED DESCRIPTION

[0020] The technical solution is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention.

[0021] The core idea of ​​the present invention is to make the multi-layer stacked fabrics shift in layers during the bending process, so that a staggered end surface appears at one end of the fabric, and the staggered end surface is used to turn over and print layer by layer, or to use the exposed area of ​​the staggered end surface for direct printing. The specific application methods are as follows: Example 1 like Figure 1 As shown, a cloth marking machine comprises: a frame s1, a roller s2 fixed to the frame s1 through a bearing as a curved surface support component, a pressing plate component S3 fixed to the frame s1 for fixing one end of the cloth 3, a staggered layer pressing component s4 fixed to the frame s1 for fixing the staggered layer end surface 30 at 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.

[0022] like Figure 2As shown, the staggered layer pressing assembly s4 comprises a first-level pressing plate driving rod s41 fixed to the frame s1, a second-level pressing plate driving rod s42 connected to the first-level pressing plate driving rod s41 through a servo motor, and a pressing plate s43 connected to the second-level pressing plate driving rod s42; the pressing plate s43 comprises a cylindrical surface adapted to the cloth. The main body of the pressing plate s43 is made of metal or engineering plastic, and its front end has a flexible elastic end s4301 to facilitate the printing wheel assembly s5 to overcome the pressure of the pressing plate on the cloth and turn over the surface layer of the cloth. The servo motor driving the first-level pressing plate driving rod s41 is arranged inside the frame s1.

[0023] 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.

[0024] 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.

[0025] like Figure 4 As shown, the numbering gear s55 has a plurality of tooth convex structures, each of which includes a cloth turning tooth tip s551 located at a tooth tip position on one side, and a printing tooth surface s552 for printing on the surface of the cloth; the cloth turning tooth tip s551 has a row of comb teeth structure to lift the surface cloth; the printing tooth surface s552 is provided with a specific shape pattern for printing numbers on the surface of the cloth; the numbering gear s55 is usually used in groups to obtain a larger coding range. The numbering gear s55 prints numbers on the surface of the cloth in the following ways: pressing down or sliding. The operation of pressing down to number 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 make it contact with the surface of the cloth, thereby completing the numbering. The operation of sliding numbering is: first, the printing tooth surface s552 contacts the end of the uppermost 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 uppermost 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 number is printed on the surface of the next layer of cloth during the sliding process. The coding form of the number is preferably a barcode to facilitate printing the number on the cloth surface in a sliding manner.

[0026] 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: Step 1: 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.

[0027] The staggered layer lamination assembly s4, the printing wheel assembly s5, and the cloth pressing wheel assembly s6 are all in a standby state.

[0028] Step 2: If Figure 5 As shown, the control power supply of the cloth pressing wheel assembly s6 is started, and the cloth pressing wheel at the front end of the cloth pressing wheel assembly s6 is extended downward by the drive of the servo motors at various levels, and then the cloth pressing wheel at the front end of the cloth pressing wheel assembly s6 is pressed on the fixed end side of the cloth 3. The staggered layer pressing assembly s4 and the printing wheel assembly s5 are both in a standby state.

[0029] Step 3: If Figure 6 As shown, driven by various levels of servo motors, 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 on 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 surface 30 at the free end of the cloth. The end surface 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.

[0030] 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.

[0031] Step 4: Figure 7 As shown, through the drive of 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 break away from the contact with the cloth 3. The printing wheel assembly s5 is started to make the numbering gear s55 contact the end surface of the first layer of cloth above the staggered end surface 30, and the top layer of cloth is turned over with the rotation of the printing tooth surface s552 and the movement of the driving slider s53 on the slide rail s52. 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, 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 number is printed on the surface of the next layer of cloth during the sliding process. The coding form of the number is preferably a barcode to facilitate the printing of the number on the surface of the cloth in a sliding manner.

[0032] 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 uppermost layer of cloth 301 to turn outward, thereby completing the printing of a layer of cloth and the lifting and turning of the upper layer of cloth.

[0033] Repeat steps 1-5 above until all the fabrics are printed layer by layer.

[0034] The drum is a horizontally placed cylinder in appearance.

[0035] First, a stack of fabric is fixed on top of the drum. Using the centripetal force generated by the rolling of the drum, the fabric will gradually spread out along the direction of the drum. This spreading process is like playing cards being evenly shuffled by a shuffler, or like a contract being stamped with a saddle seal, which is both neat and standardized. The spacing between each layer of fabric is carefully designed to be equidistant to ensure the accuracy of subsequent processing.

[0036] Once the fabric is spread out, it is time for a row of specially designed printing wheels to come into play. These printing wheels are dipped in ink and gently roll over each layer of fabric, leaving a unique mark. By adjusting the distance between the printing wheel and the fabric, we can ensure that only a unique mark is left on each layer of fabric, avoiding confusion and duplication.

[0037] These print wheels are designed with both the printing and flipping processes in mind. They have rubber teeth to increase friction with the fabric, ensuring the print wheel can hold the fabric firmly and leave a clear mark. At the same time, the inside of the print wheel is hollow and filled with ink, ensuring a clear and lasting mark every time it rolls.

[0038] The application prospects of this invention are very broad. It can not only be used for marking and identifying cloth, 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 mode of the printing wheel, we can further improve production efficiency and product quality, and bring greater value to related industries.

[0039] Another innovative numbering method, this 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.

[0040] First, we set a set of print wheels. The number of these print wheels can be adjusted as needed. For example, we can use 10 print wheels with fine print wheel marking areas at both ends for easy identification later. At the same time, these fine print wheels can also assist in grabbing the fabric. These print wheels will be used to leave marks on the fabric to achieve the purpose of numbering.

[0041] On the first layer of fabric, we grab the fabric with the first print gear from the right, leaving a mark. At this point, none of the 9 print gears on the left touch this layer of fabric. Next, on the second layer of fabric, we grab the fabric with the second print gear from the right, leaving a mark, while the first print gear is idle, and the 8 print gears on the left also do not touch the fabric. On the third layer, the first and second print gears from the right leave two marks, and the 8 print gears on the left do not touch the fabric! On the fourth layer, the third print gear from the right touches the fabric, the first and second print gears from the right are idle, and the 7 print gears on the left are idle! And so on, and so on, counting in binary! (0000000001=1, 0000000010=2, 0000000011=3, 0000000100=4, 0000000101=5, 0000000110=6, 0000000111=7 binary counting method).

[0042] The core of this numbering method is to use the binary counting method. Specifically, we can regard the state of each gear tooth as a binary bit, where 0 means no contact with the cloth and 1 means contact and leaving an imprint. In this way, we can determine the number of layers of cloth by reading the state sequence of the gear teeth. For example, when the state sequence of the gear teeth from the right is 0000000001, it represents the first layer of cloth; when the state sequence is 0000000010, it represents the second layer of cloth; and so on.

[0043] In order to easily see the binary 1, that is, the teeth on the gear, we can use different symbols instead. For example, we can use shapes such as the moon, triangle, circle, square, etc., and use one shape for every two adjacent gear teeth. In this way, when we look at the imprint on the fabric, we can quickly determine the number of layers of fabric by identifying these shapes.

[0044] In actual operation, we also need to consider how to fix the fabric in place so that the print wheel can accurately grab and leave an imprint. To do this, we can use a large roller to fix the fabric. First, use the centripetal force generated by the rolling of the roller to spread the fabric so that it is flat on the roller. Then, adjust the speed of the gear and the roller to ensure that each layer of fabric to be grabbed is at the top of the roller. When the print wheel grabs the fabric, the fabric falls back under the action of gravity, so that it will not affect the subsequent grabbing and marking work. And it is convenient to grab only one sheet! It should be noted that because the fabric is soft, only when the print wheel actually touches and grabs the fabric can it leave a mark. Therefore, in addition to the print wheels on both sides of the top grabbing each layer of fabric and leaving a mark to mark the boundary, the middle print wheel teeth and the rightmost gear teeth grab the fabric every other layer and leave a mark. The second gear from the right needs to grab two layers in a row, then leave two layers empty, and then grab two layers in a row! The third from the right needs to grab 4 layers in a row, leave 4 layers empty, and then grab 4 layers in a row. In this way, the fourth from the right needs to grab 8 layers in a row, then leave 8 layers empty, and then grab 8 layers in a row, and so on.

[0045] In addition, in order 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 speed of the gears and the characteristics of the fabric.

[0046] The solution is to adjust the shaft height starting from the second gear on the right. The second gear on the right starts with a one-layer-one-grab speed, but the gear shaft height will be raised or lowered every certain number of turns (that is, the number of layers of cloth grabbed) according to the speed of the first gear on the right or the speed of the gears at both ends of the top. Regardless of whether the gear shaft is high or low, it will keep rotating.

[0047] The gears are used to turn the cloth and print the number. There is ink in the gears. When the gears grab the cloth, they must contact the cloth, leaving an ink dot. Different layers of cloth will have gears at different positions to grab the cloth and contact the cloth, leaving different positions and different numbers of ink dots. These are binary numbers, which are equivalent to printing numbers and turning the cloth in one step! My gears are arranged in a row horizontally, at least 10 gears, (10 gears can print numbers within 1000, and more gears need to be added) For the first piece of cloth, only the first gear grabs the cloth and contacts the cloth, for the second layer of cloth, only the second gear grabs the cloth and contacts the cloth, and the third... is as follows:

[0048] In order to prevent the gears from not having enough strength to grab the cloth due to the lack of cloth, two additional gears can be added on both sides to keep grabbing the cloth, similar to the borders on both sides. In order to facilitate recognition, the ink dots can also be changed into different shapes such as triangles, moons, circles, etc. In this way, different gears grab the cloth and leave different ink dots, which can both grab the cloth and mark the number.

[0049] In summary, this binary-based marking method is highly accurate and reliable, providing clear, easy-to-read marks during fabric marking. By properly designing the gears and adjusting the shaft height, we can ensure that the gears can accurately grab the fabric and leave marks, thus achieving fast and accurate marking.

[0050] 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.

[0051] First, the diameter of the roller should be smaller than the length difference between the two layers of fabric, similar to the length difference between each card when a playing card is spread out diagonally. This design ensures that the roller can accurately control the thickness of the fabric when pressing the fabric and avoid overlapping of multiple layers of fabric.

[0052] Secondly, the roller needs to be equipped with a sensor to monitor the height change of the roller. When the height of the roller decreases, the sensor will send a signal to instruct the gear to start grabbing the cloth. In this process, the coordination between the roller and the gear is crucial. After the roller presses the cloth, the gear needs to accurately grab a single layer of cloth and quickly detach after grabbing to avoid damaging the cloth.

[0053] As the drum rolls, it moves, while the gear remains stationary. When the drum drops to a preset height (the thickness of a layer of fabric) again, the gear turns again to grab the next layer of fabric. Through this cycle, we can ensure that only one layer of fabric is grabbed at a time, thereby improving production efficiency and product quality.

[0054] In addition, in order to further improve the grabbing accuracy of the cloth, we can also install a sensor similar to a money counting machine on the drum. When the sensor detects that two pieces of cloth have been grabbed or one is missed, it will immediately send out an alarm signal, stop the machine and remind the operator to deal with it. This function can effectively avoid production problems caused by misoperation or equipment failure.

[0055] When the cloth is first fixed, the drum rolls and uses centripetal force to spread the cloth. During this process, the drum can roll over the cloth several times, and through computer statistics, the most common height difference is extracted, which is the actual thickness of the cloth. If the number of times this height appears is not more than 99% or even 100%, it means that the cloth is not flat, and an alarm may sound and manual intervention may be required. When the test is completed, in theory, the height difference should be fixed to the thickness of the cloth, and the drum will reduce the height from the highest to the lowest according to the thickness of the cloth, and the number of fixed reduction values ​​is 100%. (This process is equivalent to the counting process), and then the gears start to grab the cloth and number it. (The roller presses the cloth, the gears grab the cloth, the roller rotates, the roller reduces the height difference, and the gears grab the cloth again) The roller can also be changed to a vertical row similar to a ballpoint pen according to the actual situation. It can ensure that it has enough strength to press the cloth and can also ensure that it is small enough (the gap between the cloths, that is, the length difference mentioned above is small).

[0056] The roller below rolls to ensure that the cloth to be grabbed is turned by the gear and can be turned down under the action of gravity without affecting subsequent operations. Therefore, the roller, the roller (or the downward pressing probe), and the gear must move in coordination.

[0057] In the process of fixing and spreading the fabric, we also need to take some measures to ensure the flatness and stability of the fabric. For example, to fix the fabric on the drum, you can use a parallelogram-shaped clip (with a certain degree of softness, which can be fixed into a circular arc concentric with the drum). After fixing, rotate it to remove static electricity and shake off adhesion. Then the fabric with sufficient length can be spread evenly on the drum by using the curvature of the drum. For fabrics with short length, you can let the parallelogram clip clamp the fabric and then push it (or drive it electrically) to use external force to spread the fabric evenly on the drum.

[0058] Finally, the coordinated movement between the roller, roller (or pressed probe) and gear is also the key to achieve accurate 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.

[0059] In summary, by optimizing the design of key components such as rollers, rollers and gears and introducing technical means such as sensors and inductors, we can achieve precise grabbing and stable operation of fabrics. This not only helps to improve production efficiency and quality, but also reduces production costs and waste.

[0060] Example 2 like Fig. 9 As shown, a fabric staggered mechanism comprises: a curved surface support component 1 for supporting fabric 3 and a staggered layer pressing component 2 for forming a staggered layer end surface 30 by pressing the fabric 3; The curved surface support assembly 1 comprises an arc cylinder; The staggered-layer lamination assembly 2 comprises a cylindrical surface adapted to the fabric.

[0061] The curved surface support assembly 1 comprises: a curved surface support plate 11 having a concave cylindrical surface, and a driving assembly 12 connected to the curved surface support plate 11 .

[0062] like Fig.10 As shown, the curved support plate 11 includes: a hard support segment 111 having one end connected to the execution end of the driving 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.

[0063] The staggered-layer pressing 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 having an outer convex cylindrical surface and a bearing fixed to the end of the rotating bracket 22, and a rotating driver 24 fixed to the rotating bracket 22 and transmission-connected to the rotating pressure block 23.

[0064] The rotating pressing block 23 includes a vibrator and / or air holes. The vibrator is arranged inside the rotating pressing block 23, and can transmit vibration to the cloth 3 to promote the stratification of the cloth, which can effectively solve the adhesion between the cloths and avoid the problem of missing numbers on individual layers of cloth; the air holes are evenly distributed on the working surface of the rotating pressing block, and can achieve the effect of adsorption or blowing stratification of the cloth 2 by switching the connection with the vacuum pump or air pump through the valve.

[0065] 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 during the pressing process of the fabric.

[0066] After the pressing process of the rotating pressing block 23 is completed and the rotating pressing block 23 contacts the cloth 3, the air holes are connected to the vacuum pump through the air path, and the vacuum formed near the air holes evenly distributed on the surface of the rotating pressing block 23 can adsorb the cloth 3 and attach it to the surface of the rotating pressing block 23. At the same time, the rotating pressing block 23 is rotated to drive the cloth 3 to move layer by layer to form interlayer displacement and form a staggered end face 30. Furthermore, when used together with a vibrator, the interlayer displacement effect on the cloth can be further enhanced, the layered displacement is larger, the exposed width of each layer of cloth on the staggered end face 30 is larger, and the printing area is larger, which is conducive to improving the printing quality of the mark.

[0067] 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 numbering method of turning over each layer of fabric layer by layer for numbering, the efficiency is significantly improved, and the missed numbering rate is also significantly reduced.

[0068] Example 3 Based on the same inventive concept, the present invention also provides a cloth marking machine.

[0069] like Fig.11 As shown, the marking machine comprises: A carrying platform 4, which is fixed to an external stationary structure (usually a frame-type or box-type rack) and is used to place the stacked fabrics 3; A pressure plate assembly 5, whose fixed end is indirectly or directly connected to the supporting platform 4, and whose movable end is parallel to the supporting platform 4 to fix one end of the cloth; the pressure plate assembly 5 includes a pressure plate driver 51 and a pressure plate 52 connected to the execution end of the pressure plate driver 51; the pressure plate driver 51 includes one of a cylinder, a hydraulic cylinder, and a linear motor.

[0070] 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 are pressed and fixed to the other end of the fabric 3 and a staggered end surface 30 is formed at the end of the fabric 3; The marking machine also includes a cloth positioning component 6 which is fixed to the supporting platform 4 and can be adjusted in position, and includes a positioning drive component 61 fixed to the pressure plate platform 4, and a positioning baffle 62 connected to the driving end of the positioning drive component 61; the positioning drive component 61 and the pressure plate platform 4 are fixed by electromagnetic adsorption, and when the power is on, the positioning drive component 61 and the pressure plate platform 4 are fixed, and when the power is off, the positioning drive component 61 and the pressure plate platform 4 can move freely to adjust the position, so as to be suitable for cloth pieces of different sizes; a quick-release structure is adopted between the positioning baffle 62 and the driving end of the positioning drive component 61 to facilitate the replacement of positioning baffles 62 of different shapes, so as to realize the positioning of cloth pieces of different shapes.

[0071] The marking machine also includes a marking assembly 7, which is fixed to the platen platform 4 and arranged on the outer side of the staggered end surface 30. The marking assembly 7 includes: an arc guide rail 71 fixed to the bearing platform 4, a marking machine bracket 72 slidably fixed to the arc 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 driver 74 fixed to the other end of the marking machine bracket 72, and an arc rack 75 fixed to the arc guide rail 71 and parallel to each other; the shape of the arc guide rail 71 is adapted to the concave cylindrical surface of the curved support plate 11; the circumferential driver 74 is meshed with the arc rack 75 through a gear to adjust the position of the marking machine 73.

[0072] 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.

[0073] like Fig.12 As shown, at the staggered end face 30 of the fabric 3, an exposed part after staggering is formed between each layer of fabric; at the same time, the front end of the curved support plate 11 is a fork-shaped structure, and a window for printing is formed in the middle; a printing area is formed in the staggered exposed part of each layer of fabric. For example, a first printing area 301 is formed in the exposed part of the first layer of fabric, a second printing area 302 is formed in the exposed part of the second layer of fabric, a third printing area 303 is formed in the exposed part of the third layer of fabric, and a fourth printing area 304 is formed in the exposed part of the fourth layer of fabric; and so on, each layer of fabric will have a printing area, and different marking numbers can be printed on each layer as needed, or the same marking number can be printed on a predetermined number of layers. Specifically, the marking number can be a barcode, a digital code, or a simpler color mark to distinguish different batches of fabrics with color differences.

[0074] The working process of an example of the cloth marking machine of the present invention is as follows: Step 1. First, place multiple stacked fabric slices on the carrying platform 4; Step 2. Select a positioning baffle 62 of a suitable shape and install it on the driving end of the positioning drive assembly 61; Step 3. Adjust the position of the cloth positioning component 6 on the carrying platform 4 so that the end surface of the cloth to be numbered is located above the curved surface support component 1, and turn on the power of the electromagnetic adsorption to fix the position of the positioning drive component 61; Step 4. Turn on the power of the pressing plate driver 51, and the execution end of the pressing plate driver 51 pushes the pressing plate 52 downward to press and fix the fabric; Step 5. Turn on the power of the driving component 12, and the execution end of the driving component 12 pushes the curved support plate 11 through the through hole 41 of the carrying platform 4, and the support plate 11 continues to move upward until the lowest end of the hard support section 111 is flush with the carrying platform 4; Step 6. Turn on the power of the air supply pump of the rotating pressing block 23, and the air holes on the surface of the rotating pressing block 23 discharge air; turn on the power of the driver 21 to push the rotating bracket 22 to move downward, and during the downward movement, the air holes blow the surface of the cloth to avoid wrinkles and curling; Step 7. When the rotating pressing block 23 contacts the cloth, the power supply of the driver 21 is cut off to stop further compacting the cloth; in another embodiment, the air hole is blocked by the cloth, 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 of the driver 21; 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, and starts the vibration motor in the rotary pressing block 23 to avoid adhesion between the fabrics, while continuing to turn on the power of the driver 21 to further compact the fabrics, forming a staggered end surface 30 at the end of the fabrics; 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.

[0075] 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: Step 4'. Turn on the power of the pressure plate driver 51. When the actuator end of the pressure plate driver 51 pushes the pressure plate 52 downward, the fabric is only slightly fixed with a pressure not greater than 5N. The specific pressure needs to be determined according to the friction coefficient experiment of the fabric. The appropriate pressure can keep the fabric moderately tensile in the subsequent staggered movement, but cannot hinder the staggered movement. Step 8'. Prolong the power-on time of the rotary driver 24 and the vibration motor to drive a greater staggered displacement between the fabrics.

[0076] The above implementation processes are all examples. The specific steps and operating parameters can be adjusted according to the characteristics of the fabric and the numbering requirements. The operation can be manually operated by power control or program controlled to achieve automated numbering operations. Given that automation has been widely used in various aspects of industry and life, there are a large number of public and commercial ready-made solutions, which will not be described here.

[0077] The attached drawings of this embodiment only show the core components of a fabric marking machine, and do not describe in detail the known and necessary prior art parts such as the frame, control circuit, power supply, gas supply, gas circuit control, program control, etc. The necessary technical contents not described in this embodiment are all prior art, so no detailed description and working instructions are given one by one.

[0078] The present invention uses the end face staggered layer of the fabric to form a printing area, which simplifies the traditional form of opening the fabric layer by layer for numbering, greatly improving the numbering efficiency; the fabric is bent by a mechanical structure to achieve the end face staggered layer, which solves the problem of missing operations or opening multiple layers of fabric at one time when the traditional gear is used to open each layer of fabric, and significantly reduces the missed printing rate; the present invention facilitates the re-inspection of fabric batches by marking the edge of each layer of fabric, and improves work efficiency. The problems of missed numbers and low numbering efficiency in the prior art are solved.

[0079] Example 4 Based on the same inventive concept, the present invention also provides a method for marking cloth numbers, using a cloth marking machine as described in Example 2, such as Fig.13 As shown, the method comprises the following steps: 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; The pressing plate assembly presses and fixes the other end of the cloth; The staggered layer pressing assembly presses and fixes the fabric and forms a staggered layer end surface at the end of the fabric; The marking component is started to mark the staggered end surface.

[0081] 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.
