Description

Technical Field

[0001] This invention relates to the field of textile equipment technology, and in particular to a multifunctional fabric inspection machine. Background Technology

[0002] Fabric inspection machines are specialized equipment used in the garment industry to detect surface defects in fabrics such as cotton, wool, linen, silk, and synthetic fibers. They are primarily used in the quality control stage before production. Their core function is to assist manual visual inspection through light reflection, light guiding technology, and an inspection table, while automatically recording length, sorting rolls, and classifying defects.

[0003] The fabric inspection machine's winding device includes a frame, two rotating rollers rotatably connected to the frame, a power mechanism positioned between the frame and the two rotating rollers and driving the rotating rollers to rotate to roll the fabric, and two limiting mechanisms positioned at both ends of the frame to limit the ends of the rolled fabric.

[0004] After the winding device winds up the fabric, a plastic bag needs to be put on the rolled fabric for protection. The process of putting on the plastic bag requires two operators to work together. One operator lifts one end of the rolled fabric while the other operator puts the plastic bag on the rolled fabric, which makes the operation of putting on the plastic bag inconvenient. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional fabric inspection machine that facilitates the placement of plastic bags over rolls of fabric.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a multi-functional fabric inspection machine, comprising a fabric inspection machine body, a winding device disposed at one end of the fabric inspection machine body, the winding device comprising a frame, two rotating rollers rotatably connected to the frame, a power mechanism for driving the rotating rollers to rotate to achieve fabric roll formation, and two limiting mechanisms respectively disposed at the left and right ends of the frame, wherein a winding paper tube for rolling the fabric is disposed between the two rotating rollers, and a support shaft with both ends extending out of the winding paper tube is disposed inside the winding paper tube; two annular grooves are symmetrically disposed in the middle of the two rotating rollers, and two lifting mechanisms for lifting the rolled fabric upwards are disposed on the frame, the lifting mechanism comprising a first cylinder disposed on the frame, and an arc-shaped support plate disposed on the output shaft of the first cylinder and located at the position of the annular grooves of the two rotating rollers, the arc-shaped support plate being housed in the annular grooves of the two rotating rollers in the initial state; the limiting mechanism comprising a limiting mechanism for lifting the rolled fabric upwards, ... The frame includes a positioning plate, a telescopic shaft mounted on the positioning plate and extending and retracting on the frame, and a second cylinder positioned between the frame and the positioning plate to move the positioning plate. Symmetrically arranged at both ends of the frame are unwinding mechanisms for unwinding plastic bags. Each unwinding mechanism includes a support frame at one end of the frame, an unwinding wheel on the support frame, and a plastic bag assembly rolled onto the unwinding wheel. The plastic bag assembly consists of multiple continuously arranged and tearable plastic bags, each bag being longer than half the length of the rolled fabric. An elastic band is provided around the opening of each plastic bag, and an outlet corresponding to the support shaft is provided at the closed opening of each plastic bag. A limiting structure is provided between the positioning plate and the unwinding wheel to restrict or unlock its rotation. When the positioning plate moves towards the adjacent unwinding wheel to its limit, the limiting structure unlocks the rotation of the unwinding wheel. When the positioning plate is in other positions, the limiting structure restricts the rotation of the unwinding wheel.

[0007] By adopting the above technical solution, the operation steps for putting a plastic bag on a roll of fabric are as follows: (S1) After the fabric is rolled up, the limiting mechanism at the left end is moved to its limit state towards the unwinding wheel, so as to unlock the rotation of the unwinding wheel at the left end; (S2) The lifting mechanism near the right end is activated, and the first cylinder drives the arc-shaped support plate to move upward, lifting the roll of fabric upward. The right end of the roll of fabric is limited by the limiting mechanism at the right end to prevent slippage; (S3) Pull the plastic bag assembly at the left end and tear off a plastic bag to put on the left end of the roll of fabric; (S4) The lifting mechanism at the right end and the limiting mechanism at the left end are reset; (S5) The limiting mechanism at the right end is activated. The mechanism moves towards the unwinding wheel to its limit state to unlock the rotation of the unwinding wheel at the right end; (S6) the lifting mechanism near the left end is activated, the first cylinder drives the arc-shaped support plate to move upward, lifting the roll of fabric upward, and the left end of the roll of fabric is limited by the left end limiting mechanism to prevent slippage; (S7) the plastic bag assembly at the right end is pulled, a plastic bag is torn off and put on the right end of the roll of fabric, and the elastic band of the plastic bag put on the right end passes over the elastic band of the plastic bag put on the left end and tightens around the plastic bag; (S8) the lifting mechanism at the left end and the limiting mechanism at the right end are reset; finally, it has the function of facilitating the putting of plastic bags on the roll of fabric.

[0008] A further provision of the present invention is that the limiting structure includes an annular toothed ring disposed on the periphery of the unwinding wheel, a limiting rack disposed on the limiting plate and used to mesh with the annular toothed ring, an elastic component disposed between the limiting plate and the limiting rack and used to drive the limiting rack to move upward and mesh with the annular toothed ring, and a guide component that causes the limiting rack to disengage from the annular toothed ring when the limiting plate moves toward the adjacent unwinding wheel to its limit state.

[0009] By adopting the above technical solution, when the limiting plate moves to its limit towards the adjacent unwinding wheel, the guiding component causes the limiting rack to disengage from the annular toothed ring, thereby unlocking the rotation of the unwinding wheel and allowing the plastic bag to be unwound and torn off. When the limiting plate is in other positions, the elastic component drives the limiting rack to move upward and engage with the annular toothed ring, thereby restricting the rotation of the unwinding wheel and preventing the plastic bag from falling as the unwinding wheel rotates.

[0010] A further embodiment of the present invention includes: two guide sleeves disposed on the limiting plate, two guide shafts disposed on the limiting rack and passing downward through the guide sleeves, a first spring sleeved on the guide shafts and with both ends pressed against the limiting racks and the guide sleeves, and an anti-loosening nut threadedly connected to the lowest end of the guide shafts passing through the guide sleeves.

[0011] By adopting the above technical solution, the elastic component includes a guide sleeve, a guide shaft, a first spring, and an anti-loosening nut. The first spring can drive the limiting rack to move upward so that the limiting rack meshes with the ring gear to limit the rotation of the unwinding wheel.

[0012] A further configuration of the present invention is as follows: the guiding component includes a first wedge block disposed on the frame and a second wedge block sleeved on one end of the two guide shafts passing through the guide sleeve. After the anti-loosening nut is installed, it prevents the second wedge block from falling off. When the limiting plate moves toward the adjacent unwinding wheel to its limit state, the inclined surface of the first wedge block presses down on the inclined surface of the second wedge block, so that the limiting rack separates from the annular toothed ring.

[0013] By adopting the above technical solution, the guiding component includes a first wedge block and a second wedge block. When the limiting plate moves toward the adjacent unwinding wheel to its limit state, the inclined surface of the first wedge block presses down on the inclined surface of the second wedge block, so that the limiting rack separates from the annular toothed ring.

[0014] A further feature of the present invention is that: the support frame is provided with an auxiliary bracket for the plastic bag to pass through, and the auxiliary bracket is provided with a ceramic guide sleeve for the plastic bag to pass through. When the limiting plate moves to its limit state toward the adjacent unwinding wheel, the distance between the limiting plate and the rolled fabric is less than the distance between the ceramic guide sleeve and the rolled fabric, and the plastic bag passing through the ceramic guide sleeve hangs down to the outside of the limiting plate.

[0015] By adopting the above technical solution, an auxiliary bracket is set on the support frame, and a ceramic guide sleeve is set on the auxiliary bracket, thereby limiting the end of the untorn plastic bag; and the distance between the limiting plate and the rolled fabric is smaller than the distance between the ceramic guide sleeve and the rolled fabric, so that the plastic bag passing through the ceramic guide sleeve hangs down to the outside of the limiting plate, so as to prevent the untorn plastic bag from affecting the roll formation of the fabric.

[0016] A further provision of the present invention is that: guide rails for guiding the roll of fabric are respectively embedded between the end faces of the two limiting plates that are close to each other. The guide rails include a vertical section extending vertically upward and an inclined section located above the vertical section and extending downward. During the process of the two limiting plates approaching each other, both ends of the support shaft are embedded in the guide rails. The width of the guide rails is greater than the diameter of the support shaft. During the process of the two lifting mechanisms pushing the roll of fabric upward, the two ends of the support shaft first move to the junction of the vertical section and the inclined section. Then, the operator applies a force toward the inclined section to the roll of fabric, causing the two ends of the support shaft to enter the inclined section and roll down.

[0017] By adopting the above technical solution, during the process of the two lifting mechanisms pushing the rolled fabric upward, the two ends of the support shaft first move to the junction of the vertical section and the inclined section. Then, the operator applies a force towards the inclined section to the rolled fabric, so that the two ends of the support shaft enter the inclined section and roll down, thereby facilitating the removal of the rolled fabric from the winding device.

[0018] A further configuration of the present invention is as follows: a mounting seat is provided on the output shaft of the first cylinder, the arc-shaped support plate is hinged to the mounting seat, the hinge point of the mounting seat and the arc-shaped support plate is located on the side of the vertical plane where the center line of the support shaft is located away from the inclined section, a limiting block is provided on one side of the mounting seat to restrict the arc-shaped support plate from rotating and tilting towards the inclined section away from the guide rail, two arc-shaped shafts are provided on the side of the arc-shaped support plate near the inclined section of the guide rail, which are about the hinge axis of the arc-shaped support plate and pass through the mounting seat, and a second spring in an arc shape is sleeved on the arc-shaped shaft, with both ends pressed between the arc-shaped support plate and the mounting seat; when the support shaft moves upward to the junction of the vertical section and the inclined section, the rolled fabric has the effect of overcoming the second spring so that the arc-shaped support plate is tilted and rotated towards the inclined section, which, together with the continued lifting of the lifting mechanism, guides the support shaft to move into the inclined section and roll down.

[0019] By adopting the above technical solution, when the support shaft moves upward to the junction of the vertical section and the inclined section, the rolled fabric has the effect of overcoming the second spring so that the arc-shaped support plate is in an inclined rotation towards the inclined section. With the continued lifting of the lifting mechanism, the support shaft is guided to move into the inclined section and roll down. At this time, there is no need to use manpower to apply a force towards the inclined section to the rolled fabric, and the automatic unloading of the rolled fabric can be realized.

[0020] A further configuration of the present invention is as follows: the inclined section faces away from the fabric inspection machine body, and the side of the frame away from the fabric inspection machine is provided with two support beams for receiving the rolls of fabric rolling off the inclined section. A baffle is rotatably connected to the end of the support beam away from the frame body. A pressing mechanism is provided on the support beam, and a flexible rubber sleeve covering the pressing mechanism is provided on the support beam. A linkage mechanism is provided between the pressing mechanism and the baffle. When the roll of fabric rolls off the inclined section and falls onto the pressing mechanism, the pressing mechanism is compressed by force, and the linkage mechanism drives the baffle to rotate to a vertical state to prevent the roll of fabric from rolling off. When the pressing mechanism is not subjected to external force, the baffle is in a horizontal state after rotation.

[0021] By adopting the above technical solution, the support beam can receive the rolled fabric from the roller. When the rolled fabric rolls down from the inclined section and falls onto the pressing mechanism, the pressing mechanism is compressed by force. The linkage mechanism drives the baffle to rotate to a vertical state to prevent the rolled fabric from rolling down. When the operator lifts the rolled fabric, the pressing mechanism is not subjected to external force, and the baffle is in a horizontal state after rotation, avoiding interference with the handling of the rolled fabric.

[0022] A further configuration of the present invention is as follows: the upper surface of the support beam is provided with a receiving groove; the pressing mechanism includes a reinforcing bracket disposed between the front side of the frame and the bottom of the support beam; two lifting shafts that are lifted and lowered and whose upper ends pass through the receiving groove, a pressing plate disposed on the upper end of the two lifting shafts and located in the receiving groove; an annular plate disposed on the periphery of the lifting shaft; and a third spring sleeved on the lifting shaft and whose two ends abut against the lower surface of the annular plate and the reinforcing bracket; the flexible rubber sleeve covers the receiving groove; the linkage mechanism includes a first connecting ring disposed at the lower end of the lifting shaft; a second connecting ring disposed on the side of the baffle away from the frame; a reversing sleeve disposed at the end of the support beam away from the frame; and a cable connected at both ends to the first connecting ring and the second connecting ring and passing through the reversing sleeve. During the process of the pressing plate being acted upon by the rolled fabric and moving downward, the cable pulls the baffle to rotate to a vertical state.

[0023] By adopting the above technical solution, after the rolled fabric rolls down, the rolled fabric rolls onto the flexible rubber sleeve and presses down on the lifting shaft under the action of the third spring. The cable of the linkage mechanism pulls the baffle to rotate to a vertical state to prevent the rolled fabric rolls down. After the operator lifts the rolled fabric rolls up, the pressing mechanism and the linkage mechanism are reset, so that the baffle is in a horizontal state after rotation, avoiding interference of the baffle with the handling of the rolled fabric rolls.

[0024] A further feature of the present invention is that the inclined section faces away from the main body of the fabric inspection machine, and the side of the frame close to the main body of the fabric inspection machine is provided with a movable shelf with rollers, and the movable shelf is provided with a cavity for accommodating several rolls of fabric to be piled up after rolling off the inclined section.

[0025] By adopting the above technical solution, the rolled fabric can fall into the cavity of the mobile shelf for collection after rolling, so as to realize the automatic collection and stacking of rolled fabric.

[0026] The beneficial effects of this invention are: the lifting mechanism for lifting rolled fabric and the unwinding mechanism for unwinding plastic bags facilitate the protection of rolled fabric by covering it with plastic bags; the two plastic bags are placed on both ends of the rolled fabric, making them easy to remove during later use; and the lifting mechanism and the guide rail on the limiting plate facilitate the unloading of the rolled fabric.

[0030] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] Example 1: A multi-functional fabric inspection machine, such as Figure 1 and Figure 2 As shown, the device includes a fabric inspection machine body 1 and a winding device 2 located at one end of the fabric inspection machine body 1. The winding device 2 includes a frame 21, two rotating rollers 22 rotatably connected to the frame 21, a power mechanism 23 located between the frame 21 and the two rotating rollers 22 and driving the rotating rollers 22 to rotate to realize the roll of fabric, and two limiting mechanisms 24 respectively located at the left and right ends of the frame 21 and realizing the limiting of the two ends of the rolled fabric.

[0032] like Figure 1 , Figure 2 and Figure 8As shown, a winding paper tube 3 for rolling fabric is provided between the two rotating rollers 22. A support shaft 4 with both ends protruding from the winding paper tube 3 is provided inside the winding paper tube 3. The outer diameter of the support shaft 4 is smaller than the inner diameter of the winding paper tube 3. The support shaft 4 can be pulled out during use.

[0033] like Figure 2 and Figure 4 As shown, two annular grooves 221 are symmetrically arranged in the middle of the two rotating rollers 22. Two lifting mechanisms 25 are provided on the frame 21 for lifting the rolled fabric upwards. The lifting mechanism 25 includes a first cylinder 251 arranged on the frame 21 and an arc-shaped support plate 252 arranged on the output shaft of the first cylinder 251 and located at the position of the annular grooves 221 of the two rotating rollers 22. In the initial state, the arc-shaped support plate 252 is housed in the annular grooves 221 of the two rotating rollers 22 and does not interfere with the rolling of the fabric.

[0034] like Figure 2 As shown, the limiting mechanism 24 includes a limiting plate 241, a telescopic shaft 242 disposed on the limiting plate 241 and telescopically disposed on the frame 21, and a second cylinder 243 disposed between the frame 21 and the limiting plate 241 and driving the limiting plate 241 to move.

[0035] like Figure 2 , Figure 6 and Figure 7 As shown, the frame 21 has symmetrical unwinding mechanisms 26 at both ends for unwinding plastic bags 2631. The unwinding mechanism 26 includes a support frame 261 at the end of the frame 21, an unwinding wheel 262 on the support frame 261, and a plastic bag assembly 263 rolled up on the unwinding wheel 262. The plastic bag assembly 263 is composed of multiple continuously arranged and tearable plastic bags 2631. The length of the plastic bag 2631 is greater than half the length of the rolled fabric. The inner ring of the opening of the plastic bag 2631 is provided with an elastic band 2632. The closed opening of the plastic bag 2631 is provided with an outlet 2633 corresponding to the support shaft 4. The plastic bags 2631 on the two unwinding mechanisms 26 are used to be inserted from both ends of the rolled fabric, and the elastic band 2632 of one plastic bag 2631 passes over the elastic band 2632 of the other plastic bag 2631 and is tightened around the periphery of the plastic bag 2631. Meanwhile, the support frame 261 is provided with an auxiliary bracket 264 for the plastic bag 2631 to pass through, and the auxiliary bracket 264 is provided with a ceramic guide sleeve 265 for the plastic bag 2631 to pass through. When the limiting plate 241 moves to the limit state towards the nearby unwinding wheel 262, the distance between the limiting plate 241 and the rolled fabric is less than the distance between the ceramic guide sleeve 265 and the rolled fabric, and the plastic bag 2631 passing through the ceramic guide sleeve 265 hangs down on the outside of the limiting plate 241.

[0036] like Figure 2 , Figure 3 , Figure 6 and Figure 8 As shown, a limiting structure 27 is provided between the limiting plate 241 and the unwinding wheel 262 to limit or unlock the rotation of the unwinding wheel 262. When the limiting plate 241 moves toward the adjacent unwinding wheel 262 to the limit state, the limiting structure 27 unlocks the rotation of the unwinding wheel 262. When the limiting plate 241 is in other positions, the limiting structure 27 restricts the rotation of the unwinding wheel 262. The limiting structure 27 includes an annular toothed ring 271 disposed on the periphery of the unwinding wheel 262, a limiting rack 272 that is raised and lowered on the limiting plate 241 and used to mesh with the annular toothed ring 271, an elastic component 273 disposed between the limiting plate 241 and the limiting rack 272 and used to drive the limiting rack 272 to move upward and mesh with the annular toothed ring 271, and a guide component 274 that causes the limiting rack 272 to disengage from the annular toothed ring 271 when the limiting plate 241 moves toward the adjacent unwinding wheel 262 to its limit state.

[0037] like Figure 8 As shown, the elastic component 273 includes two guide sleeves 2731 disposed on the limiting plate 241, two guide shafts 2732 disposed on the limiting rack 272 and passing downward through the guide sleeves 2731, a first spring 2733 sleeved on the guide shafts 2732 and with both ends pressed against the limiting rack and the guide sleeves 2731, and an anti-loosening nut 2734 threadedly connected to the lowest end of the guide shaft 2732 passing through the guide sleeve 2731. The guide assembly 274 includes a first wedge 2741 mounted on the frame 21 and a second wedge 2742 sleeved on one end of the guide sleeve 2731 and two guide shafts 2732. After the anti-loosening nut 2734 is installed, it prevents the second wedge 2742 from falling off. When the limiting plate 241 moves toward the adjacent unwinding wheel 262 to the limit state, the inclined surface of the first wedge 2741 presses down on the inclined surface of the second wedge 2742 so that the limiting rack 272 separates from the annular gear ring 271.

[0038] like Figure 2 and Figure 6 As shown, guide rails 28 for guiding the roll of fabric are embedded between the end faces of the two limiting plates 241 that are close to each other. The guide rails 28 include a vertical section 281 extending vertically upward and an inclined section 282 positioned above the vertical section 281 and extending downward. As the two limiting plates 241 approach each other, both ends of the support shaft 4 are embedded in the guide rails 28. The width of the guide rails 28 is greater than the diameter of the support shaft 4. As the two lifting mechanisms 25 push the roll of fabric upward, the two ends of the support shaft 4 first move to the junction of the vertical section 281 and the inclined section 282. Then, the operator applies a force towards the inclined section 282 to the roll of fabric, causing the two ends of the support shaft 4 to enter the inclined section 282 and roll down.

[0039] like Figures 4 to 6 As shown, a mounting base 253 is provided on the output shaft of the first cylinder 251. An arc-shaped support plate 252 is hinged to the mounting base 253. The hinge point between the mounting base 253 and the arc-shaped support plate 252 is located on the side of the vertical plane where the center line of the support shaft 4 is located, away from the inclined section 282. A limiting block 254 is provided on one side of the mounting base 253 to restrict the arc-shaped support plate 252 from rotating towards the inclined section 282 away from the guide rail 28. Two arc-shaped shafts 255 are provided on the side of the arc-shaped support plate 252 near the inclined section 282 of the guide rail 28. They are wrapped around the hinge axis of the arc-shaped support plate 252 and pass through the mounting base 253. A second spring 256, which is arc-shaped and has both ends pressed between the arc-shaped support plate 252 and the mounting base 253, is sleeved on the arc-shaped shaft 255. When the support shaft 4 moves upward to the junction of the vertical section 281 and the inclined section 282, the rolled fabric overcomes the action of the second spring 255 so that the arc-shaped support plate 252 is in an inclined rotation toward the inclined section 282. With the continued lifting of the lifting mechanism 25, the support shaft 4 is guided to move into the inclined section 282 and roll down.

[0040] like Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, the inclined section 282 faces away from the main body 1 of the fabric inspection machine. On the side of the frame 21 away from the fabric inspection machine, there are two support beams 291 for receiving the rolls of fabric rolling off the inclined section 282. A baffle 292 is rotatably connected to the end of the support beam 291 away from the frame 21. A pressing mechanism 293 is provided on the support beam 291. A flexible rubber sleeve 294 covering the pressing mechanism 293 is provided on the support beam 291. A linkage mechanism 295 is provided between the pressing mechanism 293 and the baffle 292. When the roll of fabric rolls off the inclined section 282 and falls onto the pressing mechanism 293, the pressing mechanism 293 is compressed by force. The linkage mechanism 295 drives the baffle 292 to rotate to a vertical state to prevent the roll of fabric from rolling off. When the pressing mechanism 293 is not subjected to external force, the baffle 292 is in a horizontal state after rotation.

[0041] like Figure 9As shown, the upper surface of the support beam 291 is provided with a receiving groove 2911. The pressing mechanism 293 includes a reinforcing bracket 2931 provided between the front side of the frame 21 and the bottom of the support beam 291, two lifting shafts 2932 that are lifted and lowered and are inserted into the receiving groove 2911 at their upper ends, a pressing plate 2933 provided at the upper end of the two lifting shafts 2932 and located in the receiving groove 2911, an annular plate 2934 provided around the lifting shafts 2932, a third spring 2935 sleeved on the lifting shafts 2932 and with both ends pressed against the lower surface of the annular plate 2934 and the reinforcing bracket 2931, and a flexible rubber sleeve 294 covering the receiving groove 2911. The linkage mechanism 295 includes a first connecting ring 2951 located at the lower end of the lifting shaft 2932, a second connecting ring 2952 located on the side of the baffle 292 away from the frame 21, a reversing sleeve 2953 located at the end of the support beam 291 away from the frame 21, and a cable 2954 connected at both ends to the first connecting ring 2951 and the second connecting ring 2952 and passing through the reversing sleeve 2953. When the pressing plate 2933 is subjected to the action of the rolled fabric and moves downward, the cable 2954 pulls the baffle 292 to rotate to a vertical state.

[0042] The steps for placing a plastic bag 2631 on the rolled fabric are as follows: (S1) After the fabric is rolled, the left-end limiting mechanism 24 is moved to its limit towards the adjacent unwinding wheel 262 to unlock the rotation of the left-end unwinding wheel 262; (S2) The right-end lifting mechanism 25 is activated, and the first cylinder 251 drives the arc-shaped support plate 252 to move upward, lifting the rolled fabric upward. The right end of the rolled fabric is limited by the right-end limiting mechanism 24 to prevent slippage; (S3) The left-end plastic bag assembly 263 is pulled, and a plastic bag 2631 is torn off and placed on the left end of the rolled fabric; (S4) The right-end lifting mechanism 25 and the left-end limiting mechanism 24 are reset; (S5) The right-end limiting mechanism 2631 is activated. 4. Move towards the unwinding wheel 262 to its limit state to unlock the rotation of the unwinding wheel 262 at the right end; (S6) cause the lifting mechanism 25 near the left end to operate, the first cylinder 251 drives the arc-shaped support plate 252 to move upward, lifting the roll of fabric upward, and the left end of the roll of fabric is limited by the left end limiting mechanism 24 to prevent slippage; (S7) pull the plastic bag assembly 263 at the right end, tear off a plastic bag 2631 and put it into the right end of the roll of fabric, and make the elastic band 2632 of the plastic bag 2631 put into the right end pass over the elastic band 2632 of the plastic bag 2631 put into the left end and tighten around the plastic bag 2631; (S8) the lifting mechanism 25 at the left end and the limiting mechanism 24 at the right end reset.

[0043] Implementation effect: When the limiting plate 241 moves to its limit towards the adjacent unwinding wheel 262, the guide component 274 causes the limiting rack 272 to disengage from the annular gear ring 271, thereby unlocking the rotation of the unwinding wheel 262, allowing the plastic bag 2631 to be unwound and torn off. When the limiting plate 241 is in other positions, the elastic component 273 drives the limiting rack 272 to move upward and engage with the annular gear ring 271, thereby limiting the rotation of the unwinding wheel 262 and preventing the plastic bag 2631 from falling as the unwinding wheel 262 rotates. The elastic component 273 includes a guide sleeve 2731, a guide shaft 2732, a first spring 2733, and an anti-loosening nut 2734. The first spring 2733 can drive the limiting rack 272 to move upward, so that the limiting rack 272 engages with the annular gear ring 271 to limit the rotation of the unwinding wheel 262. The guide assembly 274 includes a first wedge 2741 and a second wedge 2742. When the limiting plate 241 moves toward the adjacent unwinding wheel 262 to its limit state, the inclined surface of the first wedge 2741 presses down on the inclined surface of the second wedge 2742, so that the limiting rack 272 separates from the annular gear ring 271.

[0044] During the process of the two lifting mechanisms 25 pushing the rolled fabric upward, the two ends of the support shaft 4 first move to the junction of the vertical section 281 and the inclined section 282. Then, the operator applies a force to the rolled fabric toward the inclined section 282, so that the two ends of the support shaft 4 enter into the inclined section 282 and roll down, thereby facilitating the removal of the rolled fabric from the winding device 2.

[0045] When the support shaft 4 moves upward to the junction of the vertical section 281 and the inclined section 282, the rolled fabric overcomes the action of the second spring 255 so that the arc-shaped support plate 252 is tilted towards the inclined section 282. With the continued lifting of the lifting mechanism 25, the support shaft 4 is guided to move into the inclined section 282 and roll down. At this time, there is no need to use manpower to apply a force towards the inclined section 282 to the rolled fabric, and the automatic unloading of the rolled fabric can be realized.

[0046] The support beam 291 can receive the rolled fabric from the roller. When the rolled fabric rolls down from the inclined section 282 and falls onto the pressing mechanism 293, the pressing mechanism 293 is compressed by force. The linkage mechanism 295 drives the baffle 292 to rotate to a vertical state to prevent the rolled fabric from rolling down. When the operator lifts the rolled fabric, the pressing mechanism 293 is not subjected to external force, and the baffle 292 is in a horizontal state after rotation, so as to avoid the baffle 292 interfering with the handling of the rolled fabric.

[0047] After the rolled fabric rolls down, it falls onto the flexible rubber sleeve 294 and presses down on the lifting shaft 2932 against the action of the third spring 2935. The cable 2954 of the linkage mechanism 295 pulls the baffle 292 to rotate to a vertical position to prevent the rolled fabric roll from falling. After the operator lifts the rolled fabric roll, the pressing mechanism 293 and the linkage mechanism 295 are both reset, so that the baffle 292 is in a horizontal position after rotation, so as to avoid the baffle 292 interfering with the handling of the rolled fabric roll.

[0048] Example 2: A multi-functional fabric inspection machine, such as Figure 8 and Figure 9 As shown, the difference from Embodiment 1 is that the structure at the support beam 291 is not provided. In this embodiment, the inclined section 282 faces away from the fabric inspection machine body 1, and a movable shelf 5 with rollers is provided on the side of the frame 21 close to the fabric inspection machine body 1. The movable shelf 5 is provided with a cavity 51 for accommodating several rolls of fabric to be accumulated after rolling down from the inclined section 282. Finally, the rolled fabric can fall into the cavity 51 of the movable shelf 5 for collection, so as to realize the automatic collection and accumulation of rolled fabric.
