[0019] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0020] An environmentally friendly production process for curtain fabrics comprises the following steps: Step 1: Choose natural fiber as the fabric base material, and use warm water and natural detergent to clean and degrease the natural fiber. Using warm water and natural detergent to clean the fiber can effectively remove impurities and grease to ensure the fiber is clean. In addition, using natural detergent can avoid the use of chemical detergents, reduce pollution to the environment, and improve the natural environmental protection characteristics of the fiber. Step 2: Soak the pretreated natural fibers in step 1 in a natural dye solution extracted from plants, control the dyeing temperature at 60-80°C, add natural fixatives for color fixation after dyeing, and dry the dyed natural fibers at low temperature; using natural dyes extracted from plants to replace chemical dyes (such as turmeric, indigo and safflower) can significantly reduce the discharge of toxic wastewater during the production process and meet environmental protection requirements. Controlling the dyeing temperature at 60-80°C not only saves energy, but also protects the fibers from damage by high temperatures. In addition, adding natural fixatives (such as tannic acid) for color fixation can improve the color fastness after dyeing and ensure the color durability of the curtains during long-term use; Step 3, spinning the dried natural fiber to obtain yarn; Step 4: The yarn in step 3 is passed through a circular knitting machine and knitted into curtain fabric using a knitting process; Step 5: Use natural softener to treat the surface of curtain fabrics; Use natural softener to soften curtain fabrics to improve the touch while avoiding the potential harm of chemical softeners to human body and environment; Step 6: Check the appearance of the finished curtain fabric to see if there is any damage, color difference, stains, etc. Step 7. Use the rolling equipment to roll up the qualified curtain fabrics, cut the curtain fabrics into appropriate sizes according to needs, and then classify and store them.

[0021] Traditional winding equipment needs to cut the fabric by cutting mechanism after winding the fabric of a certain size on the winding roller. After that, the staff needs to remove the full winding roller, replace it with a new one, and bond the fabric to the new one. The whole process is cumbersome, which not only reduces the work efficiency of the staff, but also has high labor intensity.

[0022] To improve this situation, refer to Figure 1-8The winding device includes a frame 1, a feeding roller 101, a first tensioning roller 102, a guide roller 103, a second tensioning roller 1021, a first winding roller 104, and a synchronous pulley mechanism for simultaneously driving the feeding roller 101 and the first winding roller 104 to rotate. Two fixed plates 105 are provided on the top of the frame 1 near the first winding roller 104, and the two fixed plates 105 are rotatably connected with a rotating plate 106, and the rotating plate 106 is tilted. The rotating plate 106 should be inclined 30 degrees to the ground. The first winding roller 104 is arranged on the side of the rotating plate 106 away from the feeding roller 101 and is rotatably connected to the rotating plate 106. The other side of the rotating plate 106 is rotatably connected with the second winding roller 107 (the position of the second winding roller 107 should be close to the bottom of the fabric but not in contact with the fabric). A switching device for switching the first winding roller 104 and the second winding roller 107 back and forth is provided on the fixed plate 105.

[0023] By setting a switching device, the second winding roller 107 can be ready when the first winding roller 104 is working, thereby realizing automatic switching, reducing downtime, and improving production continuity. In addition, the switching device makes it unnecessary for workers to re-bond the fabric to the new second winding roller 107, thereby improving work efficiency and reducing labor intensity.

[0024] Furthermore, the switching device includes a pressing mechanism for pressing the fabric onto the surface of the second winding roller 107, a cutting assembly for cutting the fabric, and a rotating mechanism for driving the rotating plate 106 to rotate. Both sides of the rotating plate 106 are rotatably connected with rotating disks 108. The first winding roller 104 and the second winding roller 107 are respectively fixedly connected to the corresponding rotating disks 108 by bolts 109. A slot 110 is provided on the side of the rotating disk 108 close to the fixed plate 105. A rotating shaft 111 is rotatably connected to one side of the fixed plate 105. A synchronous pulley mechanism is linked to the rotating shaft 111. A block 112 engaged with the slot 110 is provided on the rotating shaft 111. A sliding assembly for disengaging the block 112 from the slot 110 is provided on the rotating shaft 111.

[0025] The cutting assembly includes a second cylinder 8 and a cutting knife 801. The second cylinder 8 is fixedly connected to the side of the pressing plate 202, and the second cylinder 8 is arranged on the side of the pressing plate 202 away from the discharge roller 101. The cutting knife 801 is arranged on the telescopic rod of the second cylinder 8 and is fixedly connected to the telescopic rod.

[0026] The synchronous pulley mechanism includes a first synchronous pulley 9 fixedly connected to the discharge roller 101, a second synchronous pulley 901 fixedly connected to the rotating shaft 111, a connecting belt 902 connecting the first synchronous pulley 9 and the second synchronous pulley 901, and a driving motor 903 for driving the first synchronous pulley 9 to rotate.

[0027] When it is necessary to switch the winding roller, firstly, apply adhesive on the surface of the second winding roller 107, then start the pressing mechanism, so that the fabric is bonded to the surface of the second winding roller 107 and stays for a period of time, ensuring that the fabric is firmly adhered to the second winding roller 107. Next, start the cutting assembly to cut off the fabric connected to the first winding roller 104. After that, remove the first winding roller 104 and replace it with a new first winding roller 104. Next, make the pressing mechanism and the cutting assembly detach from the surface of the fabric, and then make the clamping block 112 detach from the clamping slot 110. Finally, start the rotating mechanism to rotate the rotating plate 106 180 degrees to replace the original position of the first winding roller 104. At this time, the clamping block 112 on the rotating shaft 111 is clamped with the clamping slot 110 on the rotating disk 108, thereby driving the rotating disk 108 to rotate. Finally, the staff starts the drive motor 903 to drive the winding device to continue working.

[0028] The switching device in this embodiment can be semi-automated, eliminating the need for frequent manual adjustments by operators, simplifying the operating process, thereby reducing the labor intensity of workers during long hours of work and improving the automation level of the equipment.

[0029] More specifically, the top of the fixed plate 105 is fixedly connected to the cover plate 201 through a plurality of guide rods 2, and the pressing mechanism includes a pressing plate 202, a first cylinder 203 that pushes the pressing plate 202 to move, a first connecting rod 204, a second connecting rod 205, and a first elastic member 206 (the first elastic member 206 can be a tension spring), the telescopic rod of the first cylinder 203 should be fixedly connected to the pressing plate 202, both sides of the pressing plate 202 are slidably connected to the guide rods 2, and a sliding groove is provided on the side of the pressing plate 202 close to the frame 1 207, sliders 208 are slidably connected on both sides of the slide groove 207, the first elastic member 206 is arranged between the two sliders 208 and is fixedly connected to the two sliders 208 respectively, one end of the first connecting rod 204 and the second connecting rod 205 are rotatably connected to the two sliders 208 respectively, and the other ends of the first connecting rod 204 and the second connecting rod 205 are rotatably connected to the pressing roller 209, the first connecting rod 204 is rotatably connected to the second connecting rod 205, and the second winding roller 107 is arranged between the two pressing rollers 209.

[0030] When in use, the staff starts the first cylinder 203, and the first cylinder 203 drives the pressing plate 202 to move in the direction close to the second winding roller 107, and the pressing plate 202 then drives the two pressing rollers 209 to contact the surface of the second winding roller 107. As the pressing plate 202 continues to move downward, the two pressing rollers 209 will adapt to the structure of the arc-shaped surface of the second winding roller 107 and gradually open, pressing most of the fabric on the surface of the second winding roller 107. When the two pressing rollers 209 open outward, the first connecting rod 204 and the second connecting rod 205 will rotate, and the other ends of the first connecting rod 204 and the second connecting rod 205 will respectively drive the slider 208 to move away from each other and stretch the first elastic member 206. When the first cylinder 203 retracts, the first elastic member 206 recovers its deformation, drives the two sliders 208 to move in the direction close to each other, and finally returns to the original position, so that the two pressing rollers 209 are reset.

[0031] The laminating mechanism in this embodiment can make most of the fabric adhere to the second winding roller 107, increase the contact area between the fabric and the second winding roller 107, ensure that the fabric is firmly adhered to the second winding roller 107, and reduce the risk of falling off. Secondly, the first elastic member 206 enables the laminating mechanism to adapt to winding rollers with similar sizes, thereby expanding the application range of the laminating mechanism and improving its practicality.

[0032] Furthermore, the rotating mechanism includes a rotating motor 3, a worm wheel 301, and a worm 302. The rotating plate 106 is rotatably connected to the fixed plate 105 through a rotating shaft 303. One end of the rotating shaft 303 passes through one side of the fixed plate 105 and extends to the outside of the fixed plate 105. The worm wheel 301 is arranged on a side of the rotating shaft 303 away from the fixed plate 105 and is fixedly connected to the rotating shaft 303. The worm 302 is meshed with the worm wheel 301, and one end of the worm 302 is fixedly connected to the output end of the rotating motor 3. The rotating motor 3 is fixedly connected to the side of the fixed plate 105 through a motor seat 304. A rotating motor 3 with a self-locking function should be selected.

[0033] When the staff starts the rotating motor 3, the output end of the motor will drive the worm 302 to rotate, and the worm 302 will then drive the worm wheel 301 to rotate, and the worm wheel 301 will then drive the rotating shaft 303 to rotate, and the rotating shaft 303 will further drive the rotating plate 106 to rotate, and finally the first winding roller 104 and the second winding roller 107 are switched through the rotating plate 106. By setting the worm wheel 301 and the worm 302, the efficiency and accuracy of the winding roller switching operation can be ensured. At the same time, the worm wheel 301 and the worm 302 have a natural self-locking characteristic, that is, when the worm wheel 301 stops rotating, the worm 302 will not rotate in the opposite direction. This means that after the first winding roller 104 and the second winding roller 107 are switched, a stable state can be maintained to avoid the retreat phenomenon caused by external interference, thereby improving the safety and reliability of the equipment.

[0034] In this embodiment, the cross-sections of the card slot 110 and the card block 112 are both square structures. The card block 112 of the square structure makes it difficult for the card block 112 to slide relative to the card slot 110, thereby ensuring that the card block 112 can transmit the rotational force to the rotating disk 108, thereby improving the reliability and stability of the winding equipment under long-term use.

[0035] The sliding assembly includes a second elastic member 5 (the second elastic member 5 can be a cylindrical compression spring), a sliding disk 501, a receiving groove 502 is provided on the side of the rotating shaft 111 close to the rotating plate 106, one end of the second elastic member 5 is fixedly connected to the side of the receiving groove 502, and the other end of the second elastic member 5 is fixedly connected to the clamping block 112. A plurality of limiting grooves 503 are provided on the side of the rotating shaft 111, and each side of the clamping block 112 is provided with a limiting block 504, each limiting block 504 is respectively slidably connected to the corresponding inner wall of the limiting groove 503, and the side of the limiting block 504 away from the clamping block 112 is fixedly connected to the sliding disk 501.

[0036] When the operator needs to switch the first winding roller 104 or the second winding roller 107, he first needs to hold the sliding disk 501 so that the sliding disk 501 drives the block 112 to move along the direction of the compression elastic member, thereby making the block 112 disengage from the slot 110. Then, the operator can start the rotating motor 3 to drive the rotating disk 108 to rotate. The sliding assembly in this embodiment is simple in design. The operator only needs to move the sliding disk 501 to make the block 112 disengage from the slot 110 without complicated operations, thereby improving the convenience of operation. In addition, the diameter of the sliding disk 501 should be larger than the diameter of the rotating disk 108, so that the sliding disk 501 can be exposed on the surface of the rotating disk 108, which is convenient for the operator to operate.

[0037] Working principle: When the staff needs to switch, firstly, the adhesive is applied to the surface of the second winding roller 107, and then the first cylinder 203 is started. The first cylinder 203 drives the pressing plate 202 to move in the direction close to the second winding roller 107, and the pressing plate 202 then drives the two pressing rollers 209 to contact the surface of the second winding roller 107. As the pressing plate 202 continues to move downward, the two pressing rollers 209 will adapt to the structure of the arc-shaped surface of the second winding roller 107, and gradually open, pressing most of the fabric on the surface of the second winding roller 107 (the fabric generally has a certain toughness). When the two pressing rollers 209 open outward, the first connecting rod 204 and the second connecting rod 205 will rotate, and the other ends of the first connecting rod 204 and the second connecting rod 205 respectively drive the slider 208 to move away from each other, and stretch the first elastic member 206, so that the pressing roller 209 stays on the surface of the second winding roller 107 for a period of time, thereby ensuring that the fabric is firmly adhered to the second winding roller 107.

[0038] Then, the second cylinder 8 is started, and the telescopic rod of the second cylinder 8 drives the cutting knife 801 to cut the fabric connected to the first winding roller 104. Then, the operator uses a tool to remove the first winding roller 104 and replace it with a new first winding roller 104. At this time, the operator needs to retract the telescopic rods of the first cylinder 203 and the second cylinder 8 and return them to their original positions.

[0039] Next, the operator slides the sliding disk 501 to drive the block 112 to disengage from the slot 110 and keep it for a while until the position of the slot 110 of the rotating disk 108 on the second winding roller 107 corresponds to the position of the block 112. Then, the rotating motor 3 is started, and the output end of the rotating motor 3 drives the worm 302 to rotate, and the worm 302 drives the worm wheel 301 to rotate, and the worm wheel 301 drives the rotating shaft 303 to rotate, and the rotating shaft 303 then drives the rotating plate 106 to rotate 180 degrees. When the slot 110 on the rotating disk 108 is aligned with the position of the block 112, the sliding disk 501 is released, and the block 112 will automatically snap into the slot 110 under the action of the second elastic member 5. If the block 112 cannot be smoothly snapped into the slot 110, the operator needs to rotate the second winding roller 107 for manual alignment to ensure that the block 112 is snapped into the slot 110.

[0040] Finally, the driving motor 903 is started, and the rotating shaft 111 is driven to rotate through the first synchronous wheel, the connecting belt 902 and the second synchronous pulley 901, and the rotating shaft 111 drives the block 112 to rotate (due to the setting of the limit block 504 and the limit groove 503, the radial freedom of the block 112 is limited, so the block 112 can only rotate with the rotating shaft 111), and the block 112 drives the rotating disk 108 to rotate. In this way, the second winding roller 107 after switching can start to wind up the fabric, avoiding the operation step of the staff to re-bond the cut fabric to the winding roller, thereby reducing labor intensity and improving work efficiency. Example

[0041] Based on Example 1, refer to Figure 3 , Figure 5 , Figure 6 Since the worm wheel 301 and the worm 302 are reduction mechanisms, the rotating plate 106 rotates relatively slowly, and the operator needs to hold the sliding disk 501 for a long time, which may cause arm pain to the operator. In order to reduce the occurrence of this situation, the side of the block 112 away from the second elastic member 5 is designed to be an arc-shaped structure, and an arc groove 6 is provided on the side of the rotating plate 106 close to the block 112, and the bottom of the arc groove 6 is inclined, the center of the arc groove 6 is coaxial with the center of the rotating shaft 303, the thickness of the rotating plate 106 is greater than the thickness of the rotating disk 108 inside the rotating plate 106, and the block 112 is slidably connected to the arc groove 6.

[0042] One side of the clamping block 112 is designed as an arc-shaped structure and an arc-shaped groove 6 is provided. The operator only needs to hold the sliding disk 501 and release the sliding disk 501 after the clamping block 112 is separated from the clamping groove 110. There is no need to wait for the rotating disk 108 on the side of the second winding roller 107 to move to the position of the clamping block 112, thereby further reducing the labor intensity of the staff and reducing the possibility of arm pain.

[0043] Secondly, the thickness of the rotating plate 106 is greater than the thickness of the rotating disk 108 inside the rotating plate 106, so that the block 112 can obtain a greater amount of compression when passing through the arc groove 6, thereby ensuring that the square side of the block 112 can be smoothly inserted into the groove 110 and drive the rotating disk 108 to rotate, thereby ensuring the reliability and stability of the switching device during long-term use.

[0044] In addition, since the positions of the block 112 and the slot 110 may be relative, the block 112 cannot be smoothly inserted into the slot 110. In order to reduce the occurrence of such a phenomenon, a first magnetic attraction structure 601 is provided on the three sides of the slider 208, and a second magnetic attraction structure 602 is provided on the fourth side of the slider 208. The first magnetic attraction structure 601 and the second magnetic attraction structure 602 have different magnetic poles, and a third magnetic attraction structure 603 that is attracted to the second magnetic attraction structure 602 is provided on the side of the rotating disk 108 close to the block 112 (the first magnetic attraction structure 601, the second magnetic attraction structure 602, and the third magnetic attraction structure 603 can be electromagnets or magnets, etc., and this embodiment does not impose too many restrictions on this).

[0045] By setting the first magnetic attraction structure 601, the second magnetic attraction structure 602 and the third magnetic attraction structure 603, when the block 112 moves to the surface of the rotating disk 108, if the position of the block 112 does not match the position of the slot 110, the first magnetic attraction structure 601 on the three sides of the block 112 will repel each other with the third magnetic attraction structure 603 on the rotating disk 108. Since the rotating disk 108 can only rotate radially, the rotating disk 108 will rotate radially under the action of the magnetic field until the second magnetic attraction structure 602 on the block 112 docks with the third magnetic attraction structure 603. In this way, the block 112 can be smoothly inserted into the slot 110 under the action of the second elastic member 5, thereby reducing the time for the staff to align. Example

[0046] Based on Example 1, refer to Figure 2In order to reduce the number of steps for the staff to apply the adhesive, a liquid storage tank 7 for storing the adhesive is provided on the top of the frame 1 in this embodiment, and the liquid storage tank 7 is provided between the two fixed plates 105. A spur gear 701 is provided on the rotating disk 108, and the spur gear 701 is provided on the side of the rotating disk 108 away from the rotating plate 106 and is fixedly connected to the rotating disk 108. An arc gear 702 is provided on the side of the top of the frame 1 close to the liquid storage tank 7, and the horizontal height of the arc gear 702 is lower than the horizontal height of the liquid storage tank 7, and the spur gear 701 is meshed with the arc gear 702.

[0047] When the operator switches the winding roller, the newly installed winding roller will pass through the liquid storage tank 7, and thus automatically carry the adhesive, which reduces the time for the operator to apply the adhesive and reduces the labor intensity. In addition, the spur gear 701 and the arc gear 702 are set to make the rotating disk 108 rotate when passing through the liquid storage tank 7, thereby driving the winding roller to rotate, ensuring that each surface of the newly installed winding roller can be evenly coated with adhesive, thereby ensuring the bonding strength between the fabric and the winding roller when switching the winding roller.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
