Description

Technical Field

[0001] The invention relates to the technical field of cloth winding, and in particular to an anti-curling cloth winding device. Background Art

[0002] In the existing cloth production process, cloth is usually transported and stored in the form of material rolls. Therefore, after the cloth is processed, it is necessary to use a winding device to roll the cloth. The winding form is generally to use a motor to drive a winding roller to rotate, so that the cloth is automatically wound around the winding roller to form a material roll. However, in the process of rolling the cloth, the two sides of the cloth are prone to roll inward and cause curling, resulting in wrinkles and curling of the rolled cloth. Especially for elastic cloth, the two sides of the cloth are affected by its own elastic force, and the curling problem is particularly serious, resulting in the thickness of the two sides of the cloth being greater than the thickness in the middle after rolling, making the rolled cloth roll an irregular circle, which affects the sorting, packaging and subsequent use of the cloth. Therefore, in the process of rolling the cloth, the two sides of the cloth need to be flattened to avoid curling of the cloth.

[0003] The patent document with publication number CN219546243U discloses a cloth winding device with an anti-warping device, including a winding device and a guiding device; the winding device includes a first base, two supporting seats are arranged on the first base, the top of the supporting seat is fixedly connected with a first bearing seat, and a winding roller shaft is rotatably connected between the left and right first bearing seats; the guiding device includes a second base, a supporting frame is also protruding from the second base, two second bearing seats are symmetrically connected to the top of the supporting frame, and a guiding roller shaft is rotatably connected between the two second bearing seats; and the anti-warping device is also included. The invention relates to a device which comprises two turning arms located on both sides of a supporting frame, one end of the turning arm being rotatably connected to the supporting frame, and the other end of the turning arm being fixedly connected to a third bearing seat, and a pressing roller shaft being rotatably connected between the left and right third bearing seats; the patent can use an anti-warping device to rely on a pressing roller wheel to press on the top of the material roll, so that the surface of the cloth can be kept flat without warping during the process of winding the cloth around the winding roller shaft, thereby ensuring that the two ends of the material roll will not bulge after the cloth is wound into a material roll, which not only ensures the beauty of the material roll, but also ensures that it will not be affected during the subsequent processing.

[0004] However, through the abutment between the pressure roller and the material roll, only the raised edges of the cloth can be flattened. For cloth with curled edges, the pressure roller may press the curled edges onto the material roll and fail to effectively flatten the curled edges. In addition, as the winding roller continues to rotate, the thickness of the material roll will gradually increase, and the abutment effect between the circumference of the pressure roller and the circumference of the material roll cannot be guaranteed, thereby failing to guarantee the flattening effect on the side edges of the cloth. Summary of the invention

[0005] The present invention provides an anti-curling cloth winding device, which aims to solve the problem that the anti-curling device in the related art can only flatten the curling on both sides of the cloth, and for the cloth with curled edges, the pressing roller may press the curled edges on the material roll and cannot effectively flatten the curled edges. In addition, as the winding roller continues to rotate, the thickness of the material roll will gradually increase, and the abutment effect between the circumference of the pressing roller and the circumference of the material roll cannot be guaranteed, thereby failing to ensure the flattening effect on the side edges of the cloth.

[0006] The present invention discloses an anti-curling cloth winding device, comprising a frame, a winding roller, a supporting structure and a driving structure 1 are arranged on the frame, the winding roller is detachably mounted on the supporting structure, the driving structure 1 is used to drive the winding roller to rotate so as to wind the cloth on the outside of the winding roller, and also comprises an anti-curling mechanism and a driving assembly arranged on the frame;

[0007] The anti-warping mechanism is provided in two groups and is symmetrically arranged on the left and right sides of the frame. Each group of the anti-warping mechanism includes two oppositely arranged spreading wheels and a driving member for driving the spreading wheels to rotate around their own axes. There is a gap between the two spreading wheels for the cloth to pass through. The two spreading wheels approach each other along the conveying direction of the cloth and form a contact portion that contacts the cloth. The movement direction of the contact portion is arranged opposite to the curling direction of the cloth, so that the curling edge of the cloth is flattened through the friction contact between the contact portion and the peripheral side of the cloth.

[0008] The driving assembly is used to drive the anti-warping mechanism to move around the circumference of the winding roller, so as to drive the end of the cloth clamped by the contact part to move, and to wind the end of the cloth on the outside of the winding roller.

[0009] The cloth is then rolled up on the reel to prevent the cloth from being thick at both ends and thin in the middle, thereby improving the quality of the roll. In addition, when a new roll of cloth is rolled up, the anti-warping mechanism can be driven by the drive assembly to move around the circumference of the roll, and the end of the cloth clamped by the contact part on the spreading wheel can be driven to move, so that the end of the cloth rotates around the roll and moves to the intersection of the unwound cloth and the roll, so that the end of the cloth is rolled into the interior of the subsequent cloth through the movement of the cloth and the rotation of the roll, and the end of the cloth is rolled up on the roll, without the need to manually roll up the end of the cloth, thereby reducing the labor intensity.

[0010] Preferably, two fixed plates are provided on the frame, and the two fixed plates are symmetrically installed on the left and right sides of the frame. Two groups of anti-warping mechanisms are respectively installed on the two fixed plates through mounting plates. Two material spreading wheels in the same group are respectively connected to the corresponding mounting plates through mounting rods, and a driving member is arranged on the mounting rod.

[0011] Preferably, a guide groove is provided on the fixed plate, and the guide groove includes a first groove section arranged longitudinally and a second groove section arranged in an arc shape, and the end of the first groove section is transitionally connected to the head end of the second groove section. When the anti-warping mechanism is located at the head end of the first groove section, the side edge of the cloth can be flattened by rotating the material spreading wheel. In the process of the anti-warping mechanism moving from the head end of the first groove section to the end of the second groove section, the end of the cloth can be rolled up on the outside of the winding roller, and the driving component is used to drive the mounting plate to move along the guide groove.

[0012] Preferably, the driving assembly includes a slider, a rack and a gear. The slider is slidably disposed in the guide groove and is fixedly connected to the mounting plate. The rack is disposed on the fixed plate along the trajectory of the guide groove. The slider is open on one side facing the rack. The gear is rotatably disposed in the slider, and the gear is meshed with the rack. The gear is a self-driving structure.

[0013] Preferably, an adjustment component for adjusting the inclination angle between the two material spreading wheels is provided on the mounting plate, and the adjustment component includes an arc-shaped slide groove and a second driving structure. The arc-shaped slide groove is provided on the mounting plate, and two rod members are connected to the end of the mounting rod toward the mounting plate, so that the mounting rod can slide in cooperation with the arc-shaped slide groove through the rod members, and the second driving structure is used to drive the rod member to slide in the arc-shaped slide groove to adjust the inclination angle of the mounting rod.

[0014] The second driving structure can drive the mounting rod to slide along the arc-shaped slide groove, adjust the inclination angle of the mounting rod, and then adjust the inclination angle of the material spreading wheel, so that the gap between the contact parts on the two material spreading wheels changes, so that the anti-warping mechanism can adapt to fabrics of different thicknesses, thereby improving the applicability of the equipment.

[0015] Preferably, the second driving structure includes an electric push rod and an adjustment frame. The electric push rod is arranged on the mounting plate, and the output end is connected to the adjustment frame for driving the adjustment frame to move. The adjustment frame is nested on the outside of the rod so that the rod can move with the adjustment frame.

[0016] Preferably, the spreading wheel is formed from a rubber material.

[0017] It can provide good flexibility and adaptability during the flattening process of the fabric, which helps to more effectively unfold the curled edge of the fabric. At the same time, it can provide appropriate friction, which helps to stabilize the fabric during the flattening process, prevent the fabric from sliding or shifting, and avoid damage to the fabric.

[0018] Preferably, when the anti-warping mechanism is located at the head end of the first section of the groove, the contact portion on the material spreading wheel is close to the intersection of the rolled fabric and the unrolled fabric.

[0019] After the curled edges on both sides of the cloth are flattened by the spreading wheel, they can be rolled up on the outside of the winding roller in a flat state, preventing the side edges of the cloth from curling again after leaving the spreading wheel, thereby avoiding the phenomenon that the cloth becomes thick at both ends and thin in the middle after being rolled up.

[0020] Preferably, the supporting structure comprises two supporting members symmetrically installed on the left and right sides of the frame, the two supporting members can be close to each other or away from each other, and the winding roller is installed between the two supporting members.

The present invention is provided with an anti-warping mechanism, so that during the process of cloth winding, both sides of the cloth can pass through the two spreading wheels on the corresponding sides, so that the warping or curling formed on the cloth side can be flattened through the friction contact between the spreading wheel and the cloth side, so that the cloth can be smoothly wound on the winding roller, avoiding the phenomenon that the rolled material roll is thick at both ends and thin in the middle, thereby improving the winding quality.

[0025] 2. When winding a new roll of material, the present invention can drive the anti-warping mechanism to move around the circumference of the winding roller through the driving component, and drive the end of the cloth clamped by the contact part to move, so that the end of the cloth rotates around the winding roller and moves to the intersection of the unwound cloth and the winding roller, so that the end of the cloth is rolled into the interior of the subsequent cloth through the movement of the cloth and the rotation of the winding roller, and the end of the cloth is rolled on the winding roller, without manual rewinding of the end of the cloth, thereby reducing labor intensity.

[0026] 3.

[0037] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] like Figures 1 to 8 As shown, an anti-curling cloth winding device of the present invention includes a frame 1, on which a winding roller 11, a guide roller 16, a supporting structure, a driving structure 1 and an anti-curling mechanism 2 are provided.

[0039] The support structure includes two support members 13 symmetrically installed on the left and right sides of the frame 1. The winding roller 11 is detachably installed between the two support members 13. The two support members 13 can be close to or away from each other so as to install and disassemble the winding roller 11. At the same time, the support mechanism can be adapted to the winding rollers 11 of different lengths to wind up the fabrics 4 of different widths. The guide roller 16 is rotatably arranged on the frame 1 to guide the unwound fabric 4 and keep the fabric 4 in a tensioned state. The driving structure is used to drive the winding roller 11 to rotate so as to wind up the fabric 4 on the outside of the winding roller 11. The dynamic structure 1 includes a motor, a transmission belt 14 and two transmission wheels 15, the two transmission wheels 15 are rotatably connected to the frame 1, and the transmission belt 14 realizes reciprocating rotation through the two transmission wheels 15, one of the transmission wheels 15 is connected to the winding roller 11, and the other transmission wheel 15 is connected to the output end of the motor. The anti-warping mechanism 2 is arranged between the guide roller 16 and the winding roller 11, and can flatten the warping and curling formed on both sides of the cloth 4 during the winding process of the cloth 4, so that the surface of the cloth 4 remains flat, thereby ensuring that the two ends of the material roll formed after the cloth 4 is wound will not bulge, so as to ensure the subsequent packaging and use of the cloth 4.

[0040] The anti-warping mechanism 2 is provided in two groups and symmetrically arranged on the left and right sides of the frame 1. Each group of the anti-warping mechanism 2 includes two oppositely arranged material spreading wheels 21 and a driving member 1 for driving the material spreading wheels 21 to rotate around its own axis. There is a gap between the two material spreading wheels 21 for the cloth 4 to pass through. The two material spreading wheels 21 approach each other along the conveying direction of the cloth 4 and form a contact portion 211 that contacts the cloth 4. The movement direction of the contact portion 211 is opposite to the curling direction of the cloth 4, so that the curling of the cloth 4 is flattened through the friction contact between the contact portion 211 and the peripheral side of the cloth 4.

[0041] Specifically, Figures 1 to 8 As shown, starting the motor can drive the transmission wheel 15 connected thereto to rotate, and under the action of the transmission belt 14, the two transmission wheels 15 rotate synchronously, thereby driving the winding roller 11 to rotate, gradually winding the cloth 4 on the outside of the winding roller 11, and pulling the unwound cloth 4 to gradually transport it in the direction close to the winding roller 11. During this process, the unwound cloth 4 will pass through the gap formed between the two spreading wheels 21, and the contact portion 211 on the spreading wheel 21 will contact the peripheral side of the cloth 4. At this time, the spreading wheel 21 is driven by the driving member to rotate around its own axis, and the movement direction of the contact portion 211 is opposite to the curling direction of the cloth 4, which can gradually flatten the curling formed on the peripheral side of the cloth 4, so that the cloth 4 can be smoothly rolled up on the outside of the winding roller 11.

[0042] It should be noted that the spreading wheel 21 is made of rubber material, which has excellent elasticity and can provide good flexibility and adaptability during the flattening process of the cloth 4, which helps to more effectively unfold the curled edge of the cloth 4. In addition, the rubber material can provide appropriate friction, which helps to stabilize the cloth 4 during the flattening process and prevent the cloth 4 from sliding or shifting, while preventing the spreading wheel 21 from causing damage to the cloth 4.

[0043] In some embodiments, a reel can be placed on the outside of the winding roller 11. When the winding roller 11 is driven to rotate by a driving structure, the reel can also be driven to rotate synchronously, and the cloth 4 is gradually wound on the outside of the reel. After completing the winding of a roll of material, the reel is removed from the winding roller 11, and then a new reel is placed to continue winding the cloth 4. By setting the reel, better winding tightness control can be provided, so that the layers of cloth 4 fit more closely and the generation of gaps and wrinkles is reduced. In addition, the reel can provide additional support and protection to facilitate subsequent handling and storage.

[0044] The frame 1 is also provided with a driving assembly for driving the anti-warping mechanism 2 to move around the circumference of the winding roller 11 to drive the end of the cloth 4 clamped by the contact portion 211 to move, and to wind the end of the cloth 4 on the outside of the winding roller 11.

[0045] Specifically, Figures 1 to 8 As shown, after completing the winding of a material roll, the cloth 4 is cut by the cutting device, and then the two support members 13 are moved away from each other to disassemble the winding roller 11, and the material roll is taken off the winding roller 11, and then the two support members 13 are moved closer to each other to continue to support and clamp the winding roller 11, and then the driving structure 1 drives the winding roller 11 to rotate, and at the same time, the anti-warping mechanism 2 is driven by the driving component to move around the circumference of the winding roller 11, and drives the end of the cloth 4 clamped by the contact portion 211 to move, so that the end of the cloth 4 rotates around the outer side of the winding roller 11 until the end of the cloth 4 moves to the intersection of the unwound cloth 4 and the winding roller 11, at this time it can be passed. By moving the cloth 4 and rotating the winding roller 11, the end of the cloth 4 is wound into the interior of the subsequent cloth 4, that is, the subsequently wound cloth 4 can cover the outer side of the end of the cloth 4, and the end of the cloth 4 is fixed on the winding roller 11. At this time, by continuing to rotate the winding roller 11, the cloth 4 can be gradually wound on the outer side of the winding roller 11. When the end of the cloth 4 is fixed, the anti-warping mechanism 2 is driven by the driving component to move in the circumferential reverse direction around the winding roller 11 for reset. In this process, the contact part 211 on the spreading wheel 21 can always contact with the cloth 4, and the curling edge formed on the peripheral side of the cloth 4 is flattened to ensure that the cloth 4 wound on the outer side of the winding roller 11 is in a flat state, thereby ensuring the winding effect.

[0046] In some embodiments, two fixed plates 12 are provided on the frame 1, and the two fixed plates 12 are symmetrically installed on the left and right sides of the frame 1. Two groups of anti-warping mechanisms 2 are respectively installed on the two fixed plates 12 through mounting plates 22. The two material spreading wheels 21 in the same group are respectively connected to the corresponding mounting plates 22 through mounting rods 23, and a driving member is arranged on the mounting rod 23.

[0047] In some embodiments, the two fixed plates 12 can be moved closer to or farther away from each other, and the distance between the two fixed plates 12 can be adjusted, thereby adjusting the distance between the two anti-warping mechanisms 2, so that the anti-warping mechanisms 2 can adapt to fabrics 4 of different widths, thereby improving the applicability of the equipment.

[0048] In some embodiments, a guide groove 121 is provided on the fixing plate 12, and the guide groove 121 includes a first groove 121a arranged longitudinally and a second groove 121b arranged in an arc shape, and the end of the first groove 121a is transitionally connected to the head end of the second groove 121b. When the anti-warping mechanism 2 is located at the head end of the first groove 121a, the side of the cloth 4 can be flattened by rotating the material spreading wheel 21. In the process of moving the anti-warping mechanism 2 from the head end of the first groove 121a to the end of the second groove 121b, the cloth 4 can be flattened. The end of the cloth 4 is wound on the outside of the winding roller 11, and the driving component is used to drive the mounting plate 22 to move along the guide groove 121. The driving component includes a slider 31, a rack 32 and a gear 33. The slider 31 is slidably arranged in the guide groove 121 and is fixedly connected to the mounting plate 22. The rack 32 is arranged on the fixed plate 12 along the trajectory of the guide groove 121. The slider 31 is open on one side facing the rack 32. The gear 33 is rotatably arranged in the slider 31, and the gear 33 is meshed with the rack 32. The gear 33 is a self-driving structure.

[0049] Specifically, Figures 2 to 7As shown, during the winding process of the cloth 4, the anti-warping mechanism 2 is at the head end of the first groove 121a. At this time, the curling edges formed on both sides of the cloth 4 can be flattened by the rotation of the unwinding wheel 21, so that the cloth 4 wound on the outside of the winding roller 11 is in a flat state. After completing the winding of one roll of material, the cloth 4 is cut off by the cutting device, and the roll is taken off. Then, the end of the cloth 4 is wound on the outside of the winding roller 11 by the driving component to carry out the winding of the next roll of material. The specific steps for realizing the winding of the end of the cloth 4 are: rotating the gear 33, and through the meshing transmission between the gear 33 and the rack 32, the gear 33 is driven to move along the length direction of the rack 32, and the slider 31 is driven to move along the length direction of the guide groove 121, thereby driving the mounting plate 22 connected to the slider 31 to move synchronously, so that the anti-warping mechanism 2 gradually moves from the head end of the first groove 121a to the second groove When the anti-warping mechanism 2 is at the end of the second groove 121b, the end of the cloth 4 just moves to the intersection of the unwound cloth 4 and the winding roller 11. At this time, the spreading wheel 21 is driven by the driving member to rotate, and the friction contact between the contact portion 211 and the cloth 4 can be used to drive the cloth 4 to move relative to the spreading wheel 21. At this time, the end of the cloth 4 can be gradually rolled into the space between the cloth 4 and the winding roller 11 through the movement of the cloth 4 and the rotation of the winding roller 11, and the subsequently wound cloth 4 can be pressed on the outer side of the end of the cloth 4, and the end of the cloth 4 is wound on the outer side of the winding roller 11. At this time, the subsequent cloth 4 can be gradually wound on the outer side of the winding roller 11 through the continued rotation of the winding roller 11.

[0050] It should be noted that when the anti-warping mechanism 2 is located at the head end of the first section groove 121a, the contact portion 211 on the unwinding wheel 21 is close to the intersection of the rolled cloth 4 and the unrolled cloth 4, so that the curled edges on both sides of the cloth 4 can be flattened by the unwinding wheel 21 and then rolled up on the outside of the winding roller 11 in a flattened state, thereby preventing the side edges of the cloth 4 from curling again after leaving the unwinding wheel 21, thereby avoiding the phenomenon that the cloth 4 becomes thick at both ends and thin in the middle after being rolled up.

[0051] In some embodiments, an adjustment component for adjusting the inclination angle between the two material spreading wheels 21 is provided on the mounting plate 22, and the adjustment component includes an arc-shaped slide groove 221 and a driving structure 2. The arc-shaped slide groove 221 is provided on the mounting plate 22, and two rods 231 are connected to the end of the mounting rod 23 facing the mounting plate 22, so that the mounting rod 23 can slide with the arc-shaped slide groove 221 through the rod 231. The driving structure 2 is used to drive the rod 231 to slide in the arc-shaped slide groove 221 to adjust the inclination angle of the mounting rod 23. The driving structure 2 includes an electric push rod 24 and an adjustment frame 25. The electric push rod 24 is provided on the mounting plate 22, and the output end is connected to the adjustment frame 25, which is used to drive the adjustment frame 25 to move. The adjustment frame 25 is nested on the outer side of the rod 231, so that the rod 231 can move with the adjustment frame 25.

[0052] Specifically, Figures 2 to 8As shown, when the inclination angle of the material spreading wheel 21 needs to be adjusted, the electric push rod 24 is started to drive the adjustment frame 25 connected thereto to move, thereby driving the rod 231 nested in the adjustment frame 25 to move. At this time, the rod 231 will slide in the arc-shaped slide groove 221. The movement of the rod 231 will change the inclination angle of the mounting rod 23 connected to the rod 231, thereby changing the inclination angle of the material spreading wheel 21 and changing the gap between the contact parts 211 on the two material spreading wheels 21, so that the material spreading wheel 21 can be adjusted according to the thickness of the cloth 4. The inclination angle can be adjusted so that the anti-warping mechanism 2 can adapt to fabrics 4 of different thicknesses, thereby improving the applicability of the equipment. In addition, when the anti-warping mechanism 2 is at the head end of the first section groove 121a and flattens the peripheral side of the fabric 4, the two spreading wheels 21 approach each other along the conveying direction of the fabric 4, so that the spreading wheel 21 contacts the fabric 4 on the side facing the conveying direction of the fabric 4, so that the fabric 4 is flattened through the friction contact between the spreading wheel 21 and the fabric 4. In the process of the anti-warping mechanism 2 moving from the head end of the first section groove 121a to the end of the second section groove 121b, the spreading wheel 21 The tilt angle of the material spreading wheel 21 does not change. When the anti-warping mechanism 2 moves from the end of the second groove 121b to the beginning of the first groove 121a for resetting, since the anti-warping mechanism 2 and the cloth 4 move in opposite directions, the contact portion 211 on the material spreading wheel 21 may hinder the movement of the cloth 4. Therefore, it is necessary to adjust the tilt angle of the material spreading wheel 21 through the adjustment component, so that the two material spreading wheels 21 move away from each other along the conveying direction of the cloth 4, so that the side of the material spreading wheel 21 away from the conveying direction of the cloth 4 contacts the cloth 4, so that the anti-warping mechanism 2 and the cloth 4 move in the opposite direction. In the process, the material spreading wheel 21 can continue to apply a force on the cloth 4 in the opposite direction to the curling direction, which can not only flatten the curling formed on the side of the cloth 4, but also avoid wrinkles in the rolled-up area, thereby improving the rolling effect of the cloth 4. When the anti-warping mechanism 2 moves to the head end of the first groove 121a, the anti-warping mechanism 2 stops moving. At this time, the inclination angle of the material spreading wheel 21 is adjusted again through the adjustment component, so that the material spreading wheel 21 contacts the cloth 4 again on the side facing the conveying direction of the cloth 4, so as to continue to flatten the cloth 4 through the friction contact between the material spreading wheel 21 and the cloth 4.
