Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric production, and more specifically to a fabric inspection device for nonwoven fabric production. Background Technology

[0002] During the production of nonwoven fabrics, stains and hair are easily found on the surface, necessitating inspection. Currently, there are inspection devices and systems that use industrial CCD cameras to scan the surface of nonwoven fabrics, effectively detecting surface quality. However, while these devices and systems can reliably inspect nonwoven fabrics, they cannot address the stains detected. Therefore, it is necessary to provide a fabric inspection device capable of treating surface stains on nonwoven fabrics. Summary of the Invention

[0003] The purpose of this invention is to provide a fabric inspection device for nonwoven fabric production, which can achieve rapid and reliable fabric inspection on both sides of the nonwoven fabric surface.

[0004] The present invention is implemented using the following technical solutions.

[0005] A fabric inspection device for nonwoven fabric production, characterized in that: it includes an unwinding device for unwinding and feeding nonwoven fabric rolls, a fabric inspection device for inspecting nonwoven fabric, and a winding device for winding up the inspected nonwoven fabric. The fabric inspection device has an A conveying section and a B conveying section for conveying nonwoven fabric. An A fabric inspection section and a B fabric inspection section are arranged sequentially on the sides of the A conveying section and the B fabric inspection section for inspecting the A side and the B side respectively. The A side and the B side are the two surfaces of the conveyed nonwoven fabric. The nonwoven fabric at the A conveying section and the B conveying section is conveyed at an inclined position.

[0006] A further proposed solution is that the nonwoven fabric at both conveyor sections A and B is conveyed at an angle downwards.

[0007] Next to conveyor section A and conveyor section B, respectively, there are operation sections A and B, which are used to accommodate operators to inspect the nonwoven fabric conveyed on conveyor section A and conveyor section B. The inspection operation is to remove stains from the nonwoven fabric.

[0008] Fabric inspection section A and fabric inspection section B are installed on the fabric inspection machine frame. Fabric inspection section A includes an A light source device located on the lower side of the nonwoven fabric and an A indicator device located on the upper side of the nonwoven fabric for indicating the location of stains. Fabric inspection section B includes a B light source device located on the lower side of the nonwoven fabric and a B indicator device located on the upper side of the nonwoven fabric for indicating the location of stains.

[0009] Light source device A includes a plate-shaped A light source plate arranged at an angle, and light source device B includes a plate-shaped B light source plate arranged at an angle. Non-woven fabric is conveyed parallel to light source plates A and B on the outside of light source plates A and B, respectively. The light emitted by light source plates A and B is directed onto the non-woven fabric conveyed on the outside.

[0010] Conveying section A is located upstream of conveying section B, and the height of light source board A is less than the height of light source board B.

[0011] The tilt angle of light source A is the same as that of light source B, but the tilt directions are opposite. The non-woven fabric on the outside of light source A is conveyed obliquely downward along the tilt direction of light source A, and the non-woven fabric on the outside of light source B is conveyed obliquely downward along the tilt direction of light source B.

[0012] Rollers A11 and A12 are respectively installed on the upper and lower sides of light source plate A, and rollers B11 and B12 are respectively installed on the upper and lower sides of light source plate B. Rollers A11 and B11 are matched in height and arranged close to each other. Nonwoven fabric is guided and conveyed sequentially by rollers A11, A12, B11 and B12. The A side of nonwoven fabric A is in contact with the roller surface of roller A11, the B side of nonwoven fabric A is in contact with the roller surface of roller A12, the A side of nonwoven fabric A is in contact with the roller surface of roller B11, and the A side of nonwoven fabric A is in contact with the roller surface of roller B12.

[0013] Roller A2 is positioned between rollers A12 and B11, with the B side of nonwoven fabric A in contact with the roller surface of roller A2.

[0014] A transition conveyor is provided between the unwinding device and the fabric inspection device. The transition conveyor is used to transitionally convey the unwound nonwoven fabric. Operation section A is the A travel passage between the transition conveyor and the fabric inspection device. The nonwoven fabric is conveyed above the A travel passage. Operation section B is the B travel passage between the fabric inspection device and the winding device. A traveling frame is provided at the B travel passage. Rollers C11 and C12 are provided on the traveling frame. The nonwoven fabric is conveyed around rollers C11 and C12 from the bottom side of the traveling frame. The B side of the nonwoven fabric is in contact with roller C11 and roller C12.

[0015] The technical solution provided by this invention can reliably inspect nonwoven fabrics after stain detection and reliably remove stains from the surface of nonwoven fabrics. Attached Figure Description

Detailed Implementation

[0027] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0028] As used herein, the terms “parallel,” “perpendicular,” and the like are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors.

[0029] like Figure 1 , 2 As shown, a fabric inspection device for nonwoven fabric production includes an unwinding device 300 for unwinding and feeding nonwoven fabric rolls, a fabric inspection device 100 for inspecting nonwoven fabric, and a winding device 200 for winding up the inspected nonwoven fabric. The fabric inspection device 100 has an A conveying section and a B conveying section for conveying nonwoven fabric. An A inspection section and a B inspection section are arranged sequentially on the sides of the A conveying section and the B inspection section for inspecting the A side and the B side respectively. The A side and the B side are the two surfaces of the conveyed nonwoven fabric. The nonwoven fabric at the A conveying section and the B conveying section is conveyed at an inclined position.

[0030] The nonwoven fabric is conveyed at an angle and inspected, which makes it easier to set up inspection sections A and B, simplifies the structure and manufacturing cost of the inspection equipment, and makes it easier for operators to observe and inspect the nonwoven fabric.

[0031] Furthermore: The nonwoven fabric at both conveyor sections A and B is conveyed at an angle downwards. Operating sections A and B are respectively located beside conveyor sections A and B to accommodate operators performing fabric inspection operations on the nonwoven fabric conveyed on them. The inspection operation involves the operator removing stains from the nonwoven fabric. This allows conveyor sections A and B to be arranged adjacently in the fabric inspection equipment, resulting in a smaller equipment size, reduced space requirements along the fabric conveying direction, and lower requirements for the size of the nonwoven fabric production system. The main purpose of operating sections A and B is to facilitate operators' observation of the fabric inspection process and the fabric conveying status, to facilitate fabric inspection operations at these sections, and to view the inspection results on a display device. Specifically, the inspection operation involves the operator using tools (such as tweezers) to remove or discard stains from the nonwoven fabric.

[0032] Specifically, such as Figure 3 , 4As shown: Inspection Unit A and Inspection Unit B are installed on the inspection machine frame 101. Inspection Unit A includes an A light source device located on the lower side of the nonwoven fabric and an A indicator device located on the upper side of the nonwoven fabric to indicate the location of stains. Inspection Unit B includes a B light source device located on the lower side of the nonwoven fabric and a B indicator device located on the upper side of the nonwoven fabric to indicate the location of stains. A control device is also included. Since the inspection device on the nonwoven fabric production line has already detected stains on the nonwoven fabric, during inspection, the control device, based on the inspection results from the production line (including the location of stains on the nonwoven fabric), can adjust the A and B indicator devices to indicate the stains when the nonwoven fabric is unwound and conveyed on the inspection equipment. Due to the large width of the nonwoven fabric, the indication from the A and B indicator devices eliminates the need for operators to spend time searching for stains, facilitating the inspection operation. A display device can also be installed to view the unremoved stains on the nonwoven fabric and the results of the fabric inspection operation. This invention mainly improves the mechanical structure of the fabric inspection process; the data analysis and processing, and the equipment control logic can be implemented as before, and will not be elaborated further. Operators can view the results of the nonwoven fabric inspection by checking the content displayed on the display device. The displayed content can specifically include the location, quantity, and distribution of unremoved stains, as well as the status of treated stains. An A-type detection mechanism can also be installed to detect the speed of the nonwoven fabric conveying process, and a B-type detection mechanism can be installed to detect the tension of the nonwoven fabric. The control device analyzes and processes the signals detected by inspection unit A, thus clearly knowing the position of the nonwoven fabric on the nonwoven fabric roll at inspection units A and B. Based on the stain detection results on the previous nonwoven fabric production line, it can analyze whether there are stains on the nonwoven fabric at inspection units A and B, and the location of the stains. This allows the A and B indicating devices to be adjusted to indicate the stain locations, facilitating quick stain removal by operators and improving the efficiency of fabric inspection.

[0033] Furthermore: Light source A includes an inclined plate-shaped light source plate 121, and light source B includes an inclined plate-shaped light source plate 122. Nonwoven fabric is conveyed parallel to light source plates 121 and 122 on their outer sides. The light emitted from light source plates 121 and 122 is directed onto the conveyed nonwoven fabric. Conveying section A is located upstream of conveying section B, and the height of light source plate 121 is less than the height of light source plate 122. The inclination angles of light source plate 121 and light source plate 122 are the same but opposite in direction. The nonwoven fabric on the outer side of light source plate 121 is conveyed obliquely downwards along the inclination direction of light source plate 121, and the nonwoven fabric on the outer side of light source plate 122 is conveyed obliquely downwards along the inclination direction of light source plate 122. A11 roller 111 and A12 roller 112 are respectively arranged on the upper and lower sides of light source plate 121. B11 roller 113 and B12 roller 114 are respectively arranged on the upper and lower sides of light source plate 122. The heights of A11 roller 111 and B11 roller 113 are matched and arranged close to each other. The nonwoven fabric is guided and conveyed sequentially by A11 roller 111, A12 roller 112, B11 roller 113 and B12 roller 114. The A side of the nonwoven fabric is in contact with the roller surface of A11 roller 111, the B side of the nonwoven fabric is in contact with the roller surface of A12 roller 112, the A side of the nonwoven fabric is in contact with the roller surface of B11 roller 113, and the A side of the nonwoven fabric is in contact with the roller surface of B12 roller 114. A roller 115 is provided between rollers 112 and 113, and the B side of the nonwoven fabric A is in contact with the roller surface of roller 115.

[0034] The nonwoven fabric is guided and conveyed by rollers A11 (111), A12 (112), B11 (113), and B12 (114) in the above structure. This ensures that the A side of the nonwoven fabric can be well inspected when passing through the A light source device and A indicator device, and the B side can be well inspected when passing through the B light source device and B indicator device. Furthermore, the structure is compact and occupies little space, enabling reliable conveying and inspection of the nonwoven fabric. The A and B light source devices make stains clearer, facilitating the inspection operation.

[0035] like Figure 4 As shown: The A indicator device includes an A1 mounting rod 141 and A indicator lights spaced apart on the A1 mounting rod 141. The A1 mounting rod 141 is rotatably and adjustablely mounted inside the A cover 151. The B indicator device includes a B1 mounting rod 142 and B indicator lights spaced apart on the B1 mounting rod 142. The B1 mounting rod 142 is rotatably and adjustablely mounted inside the B cover 152. An A2 mounting rod 131 is provided on the outer side of the A12 roller 112. An A operation button is provided on the A2 mounting rod 131 spaced apart. A B2 mounting rod 132 is provided on the outer side of the B12 roller. A B operation button 133 is provided on the B2 mounting rod 132 spaced apart.

[0036] The adjustable mounting rods A1 141 and B1 142 allow for angle adjustment of indicator lights A and B, facilitating installation and debugging to adapt to different image acquisition needs. Operation buttons A and B 133 correspond to indicator lights A and B, respectively. Indicator lights A and B can be infrared positioning lights or spotlights. Infrared positioning lights project a red dot onto the stain, while spotlights project a circular light area onto the stain, enabling operators to quickly identify and remove stains, improving fabric inspection efficiency. Operation buttons A and B 133 control the status of indicator lights A and B, respectively. When the control device detects stains on the nonwoven fabric passing through inspection section A / inspection section B, it adjusts the winding and unwinding devices to stop conveying the nonwoven fabric, and adjusts indicator lights A and B to indicate or illuminate the stains on the nonwoven fabric at inspection sections A and B. After the operator removes a stain, the operator adjusts the corresponding operation button A / B to turn off the corresponding indicator light A / B. Once all stains on the nonwoven fabric at inspection sections A and B have been removed and indicator lights A and B are off, the control device restarts the winding and unwinding devices to convey the nonwoven fabric again.

[0037] When the nonwoven fabric roll is placed onto the unwinding device, the previously detected stain data on the roll is simultaneously transmitted to the control device. This stain data includes the location (distribution) of the stains on the roll. After the nonwoven fabric is unwound, the control device can adjust the operation of each component of the fabric inspection equipment based on the received stain data and the unwinding and conveying status of the nonwoven fabric, thus achieving a fast and convenient fabric inspection operation.

[0038] The stain on surface A of the nonwoven fabric is designated as stain A, and the stain on surface B of the nonwoven fabric is designated as stain B. The control device regulates the winding and unwinding devices to transport the nonwoven fabric. When the control device analyzes that the nonwoven fabric with stain A has reached the A inspection section and / or the nonwoven fabric with stain B has reached the B inspection section, the control device adjusts the winding and unwinding devices to stop transporting the nonwoven fabric. It also adjusts the A indicator light and / or B indicator light at the corresponding A stain and / or B stain to indicate or illuminate the stain. The operator removes the A stain located in the A inspection section and / or the B stain located in the B inspection section according to the indications of the A and / or B indicator lights. Simultaneously, the corresponding A operation button and / or B operation button are adjusted to turn off the corresponding A indicator light and / or B indicator light. When the control device analyzes that all stains in the A inspection section and / or the B inspection section have been removed and both the A and B indicator lights are turned off, the control device adjusts the winding and unwinding devices to continue transporting the nonwoven fabric. This process is repeated until all A and B stains on the nonwoven fabric roll are removed.

[0039] For example, a stain A is located 1 meter to the left of a 400-meter section of nonwoven fabric on side A, and a stain B is located 2 meters to the left of a 350-meter section on side B. When the nonwoven fabric is unwound, when the fabric at stain A reaches the inspection section A, the control device stops the winding and unwinding devices from conveying the fabric. The corresponding indicator light on the inspection section A illuminates or marks stain A. The operator removes stain A according to the indicator light. After removing stain A, the operator adjusts the corresponding operation button at stain A to turn off the corresponding indicator light. Once the control recognizes that stains at both inspection sections A and B have been removed and that indicator lights A and B are both off, the winding and unwinding devices resume conveying the nonwoven fabric. When the nonwoven fabric at stain B reaches the inspection section B, the control device adjusts the winding and unwinding devices to stop conveying the nonwoven fabric. The B indicator light at the corresponding position on the inspection section B is adjusted to indicate or illuminate the stain B. The operator removes the stain B according to the indication of the B indicator light. After removing the stain B, the operator adjusts the B operation button 133 at the corresponding stain B to turn off the corresponding B indicator light. The control device recognizes that the stains at the inspection sections A and B have been removed and that the A and B indicator lights are both off. The control device then adjusts the winding and unwinding devices to continue conveying the nonwoven fabric.

[0040] like Figure 1 , 5 As shown in Figure 6: A transition conveying device 400 is provided between the unwinding device 300 and the fabric inspection device 100. The transition conveying device 400 is used to transitionally convey the unwound nonwoven fabric. The A operating section is the A travel passage provided between the transition conveying device 400 and the fabric inspection device 100. The nonwoven fabric is conveyed above the A travel passage. The B operating section is the B travel passage provided between the fabric inspection device 100 and the winding device 200. A traveling frame 500 is provided at the B travel passage. A C11 roller 511 and a C12 roller 512 are provided on the traveling frame 500. The nonwoven fabric is conveyed from the lower side of the traveling frame 500 around the C11 roller 511 and the C12 roller 512. The B side of the nonwoven fabric is in contact with the C11 roller 511 and the C12 roller 512.

[0041] Since the height of the B inspection section is greater than that of the A inspection section, the setting of the walking frame 500 allows the operator to easily observe and inspect the non-woven fabric on the outside of the B light source plate 122. The non-woven fabric is transported from below the walking frame 500, which effectively avoids any impact on the non-woven fabric transport.

[0042] The transition conveying device 400 includes a transition conveying frame 401, on which a row of upper transition conveying rollers 411 and a row of lower transition conveying rollers 412 are arranged. Three upper transition conveying rollers 411 are spaced apart, and two lower transition conveying rollers 412 are spaced apart. The upper transition conveying rollers 411 and lower transition conveying rollers 412 are arranged alternately along the horizontal conveying direction of the nonwoven fabric. The nonwoven fabric is conveyed in a meandering manner between the upper transition conveying rollers 411 and the lower transition conveying rollers 412. The A side of the nonwoven fabric is in contact with the roller surface of the upper transition conveying roller 411, and the B side of the nonwoven fabric is in contact with the roller surface of the lower transition conveying roller 412.

[0043] By setting up transition conveyor rollers, the problem of lifting and conveying nonwoven fabric during the unwinding process can be effectively solved. At the same time, it plays a stabilizing role in the conveying of nonwoven fabric and adjusting and stabilizing the tension of nonwoven fabric.

[0044] The present invention also provides a nonwoven fabric winding device 200, such as... Figure 7 As shown: It includes a winding frame, on which a winding guide roller group for guiding nonwoven fabric and a winding mounting mechanism are provided. The winding mounting mechanism includes two winding mounting parts 210 arranged opposite to each other. The two ends of the winding shaft are respectively detachably mounted on the two winding mounting parts 210. The winding mounting parts 210 are movably mounted on the winding frame along the A direction, which is the horizontal conveying direction of the nonwoven fabric.

[0045] By setting the winding mounting part 210 of the assembly winding shaft to an adjustable structure along the A direction, the position of the winding shaft can be adjusted as the winding shaft is continuously wound, thereby achieving reliable winding of the nonwoven fabric after inspection.

[0046] Further, such as Figure 8 , 9 As shown: The winding mounting section 210 includes a winding mounting slide 211 and a winding assembly seat 212. The winding mounting slide 211 is slidably mounted on the winding bracket 213 along direction A. The winding assembly seat 212 is fixedly mounted on the winding mounting slide 211. The winding assembly seat 212 is provided with a V-shaped or arc-shaped support slot 215 for supporting the end of the winding shaft. The opening of the support slot 215 is arranged facing upward. The winding assembly seat 212 is also provided with a limiting member 214 for preventing the end of the winding shaft from disengaging from the support slot 215. The limiting member 214 is movably mounted on the winding assembly seat 212.

[0047] The support bayonet 215 and the limiting member 214 with this structure can reliably meet the clamping requirements of the take-up shaft without affecting the operation of the take-up shaft. The assembly and unloading operations of the take-up shaft are convenient and quick.

[0048] Specifically, such as Figure 8 , 9 As shown: The limiting member 214 is composed of a circular pressure rod arranged along direction A. The limiting member 214 is installed at the upper end of the flipping bracket, and the lower end of the flipping bracket is rotatably installed on the winding assembly 212 via axis A1. The winding assembly 212 is also provided with a vertically arranged flipping adjustment cylinder 217. The cylinder body of the flipping adjustment cylinder 217 is hinged to the winding assembly 212 via axis A21, and the piston rod of the flipping adjustment cylinder 217 is hinged to the flipping bracket via axis A22. A1, A21, and A22 axes are parallel to each other and are all arranged along direction A. The winding assembly 212 is also provided with a guide member 216 for centering the winding shaft. The guide member 216 is located outside the support bayonet 215. The guide member 216 is provided with an inclined guide slope, and the height of the guide slope gradually increases along direction B. Direction B is the horizontal direction from the support bayonet 215 to the guide member 216. The flipping bracket consists of two spaced-apart movable plates arranged opposite each other. The two movable plates are rotatably mounted on the outside of the winding assembly seat 212. The two ends of the limiting member 214 are mounted on the upper ends of the two movable plates. The gap between the two movable plates is used to avoid the guide member 216.

[0049] The guide component 216 reduces the precision requirements during the loading of the take-up reel. Guided by the guide component 216, the take-up reel can automatically center itself, preventing the nonwoven fabric from being misaligned with the reel. This enables the use of AGVs for automatic assembly and unloading of the take-up reel, supporting fully automated nonwoven fabric production. The aforementioned flip-up bracket structure allows for convenient and rapid switching between the working position and the clearance position, while simultaneously not occupying the assembly space of the take-up reel, resulting in lower manufacturing costs.

[0050] A more specific implementation is as follows: the winding frame includes winding support frames 201 arranged at intervals along direction B, and winding mounting slides 211 are slidably mounted on the winding support frames 201. The winding mounting slides 211 include a horizontal slide plate portion and a vertical slide plate portion, which are arranged in an inverted L shape. The vertical slide plate portion is located inside the winding support frame 201, and an identification code 222 is provided on the vertical slide plate portion. The winding assembly seat 212 is mounted on the horizontal slide plate portion and is in an inverted L shape. The tilting adjustment cylinder 217 is mounted on the outside of the winding support frame 201.

[0051] More specifically, the winding assembly 212 includes an upward-facing grooved component mounted on a horizontal slide plate. A support latch 215 is provided on one side wall of the grooved component, and a guide 216 is disposed within the groove cavity. An A2 sensor 232 for inspecting the end of the take-up shaft is also provided at the bottom of the grooved component. An A1 sensor 231 for inspecting the nonwoven fabric roll is provided on the outer surface of the mounting plate 221. By analyzing and processing the signals from the A1 sensor 231 and A2 sensor 232, the state at the winding mounting section 210 can be accurately identified, thereby achieving reliable automatic handling and management of the shaft and the nonwoven fabric roll. Specifically, a suspended, vertically arranged mounting plate 221 can be provided on the inner side of the vertical slide plate, and an identification code 222 can be provided on the surface of the mounting plate 221. The identification code 222 can specifically be a barcode (QR code). By identifying the barcode, the operation of nonwoven fabric in the entire production system can be clearly recorded, enabling precise control of the transportation of nonwoven fabric in the entire production workshop and accurate recording of materials, facilitating the transmission of stain data.

[0052] Furthermore, the upper part and inner side of the winding support frame 201 are respectively provided with slide rails, and the horizontal slide plate and the vertical slide plate are respectively provided with sliders for sliding assembly with the slide rails. The winding support frame 201 is slidably mounted on the winding base 202 along the B direction. The winding base 202 is provided with a winding adjustment cylinder 203 for adjusting the movement of the winding support frame 201 along the B direction. A gap clearance part is provided at the lower part of the end of the winding support frame 201 away from the fabric inspection device 100. The vertical slide plate is connected to the moving adjustment cylinder 218. The moving adjustment cylinder 218 adjusts the movement of the winding mounting slide 211 along the A direction. Specifically, the moving adjustment cylinder 218 can be a leverless cylinder mounted on the inner side of the winding support frame. The control device adjusts the leverless cylinder according to the outer diameter of the nonwoven fabric on the take-up shaft and the unwind shaft, thereby adjusting the position of the take-up mounting slide 211 and the unwind mounting slide, thus achieving reliable unwinding and take-up control.

[0053] The clearance section 206 is designed to allow the AGV to move to the underside of the winding support frame 201, away from the fabric inspection device 100, so that the high-positioned winding shaft can be placed onto the winding mounting section 210 or the wound nonwoven fabric roll can be removed. The winding support frame 201 is slidably installed along direction B to facilitate installation and adjustment, and to adapt to the production and installation needs of nonwoven fabrics of different sizes.

[0054] In detail: The take-up guide roller assembly includes an A1 take-up roller 204, and an A2 take-up roller 205 is also provided on the take-up frame. The two ends of the A1 take-up roller 204 and the A2 take-up roller 205 are respectively rotatably mounted on two take-up support frames 201. The A1 take-up roller 204, the A2 take-up roller 205, and the take-up shaft are arranged sequentially at intervals along the A direction. The height of the A1 take-up roller 204 is greater than the height of the A2 take-up roller 205, and the outer diameter of the A2 take-up roller 205 is greater than the outer diameter of the A1 take-up roller 204. The outer wall of the A2 take-up roller 205 is made of rubber material, and there are grooves on the outer wall of the A2 take-up roller 205. The A2 take-up roller 205 drives the non-woven fabric roll on the take-up shaft to rotate and take up. The take-up mounting part 210 is adjusted to move along the A direction so that the outer surface of the non-woven fabric roll on the take-up shaft is close to the A2 take-up roller 205. As the nonwoven fabric roll is continuously wound up, its outer diameter gradually increases. By adjusting the position of the winding shaft, the A2 winding roller 205 can reliably drive the nonwoven fabric roll and simultaneously guide the nonwoven fabric reliably. The notches can be set to a mesh pattern.

[0055] The nonwoven fabric is wrapped and guided from the top of the A1 take-up roller 204, and from the bottom of the A2 take-up roller 205. The structure of the take-up shaft 001 is as follows: Figure 10 As shown, the take-up shaft 001 has rotatably assembled sleeves 002 at both ends. The outer surface of the sleeve 002 has an assembly ring groove 003. During assembly, the assembly ring groove 003 is fitted into the support bayonet 215, and the adjusting limiting member 214 is fitted into the assembly ring groove 003 to press the sleeve 002 tightly. This causes the A2 take-up roller 205 to drive the nonwoven fabric roll on the take-up shaft 001 to rotate, causing the take-up shaft 001 to rotate within the sleeve 022, achieving reliable and convenient take-up. One end of the A2 take-up roller 205 is connected to a take-up drive motor.

[0056] The unwinding device 300 has the same structure as the winding device 200, but the installation direction is opposite. That is, it includes an unwinding frame, on which an unwinding shaft, an A2 unwinding roller 302, and an A1 unwinding roller 301 are sequentially arranged along direction A. Both ends of the unwinding shaft are mounted on two unwinding mounting parts on the unwinding frame. The unwinding mounting parts and the winding mounting parts 210 have the same structure. The A1 unwinding roller 301 and the A1 winding roller 204 have the same structure, as do the A2 unwinding roller 302 and the A2 winding roller 205. The A2 unwinding roller 302 drives the nonwoven fabric roll on the unwinding shaft to rotate and unwind the fabric. The A1 unwinding roller 301 guides the unwound nonwoven fabric. The unwound nonwoven fabric is wrapped and guided from the lower part of the A2 unwinding roller 302 and from the upper part of the A1 unwinding roller 301. One end of the A2 unwinding roller 302 is connected to a winding drive motor. The control device regulates the operating status of the winding drive motor and the unwinding drive motor, thereby achieving reliable unwinding and winding control.
