Description

Technical Field

[0001] The present invention relates to the field of fabric winding equipment, and particularly to a fabric winder. Background Art

[0002] A winder is a material receiving device for a processing production line, which is used to wind raw materials into coils by mechanical means and is widely used in processing production lines such as paper rolls, fabric rolls, and plastic rolls.

[0003] A prior application with the authorization number CN217780237U discloses a worsted fabric winder, which includes an operation platform. A feeding mechanism and a winding mechanism are arranged on the operation platform. The feeding mechanism is two parallel conveying rollers respectively driven by motors, and the winding mechanism includes a winding roller rotatably arranged between two mounting seats. A placement groove is arranged on the winding roller, and a clamping plate is arranged in the placement groove. The winding roller can be vertically lifted to adapt to the winding of fabrics with different thicknesses.

[0004] The above-mentioned winder cannot adapt to the winding of fabrics with different widths, and as a component of the equipment, the winding roller cannot automatically discharge the fabric roll after the fabric is wound and adapt to the winding of the next piece of fabric, so there is room for improvement. Summary of the Invention

[0005] Aiming at the disadvantages that the existing fabric winder is not suitable for winding fabrics with different widths and cannot automatically discharge the fabric after winding, the present invention provides a fabric winder that can automatically discharge the fabric and adapt to the winding of fabrics with different widths.

[0006] In order to solve the above technical problems, the present invention is solved by the following technical solutions: A fabric winder includes an operation table, a feeding mechanism and a winding mechanism arranged on the operation table. The winding mechanism includes a plurality of winding drums with different lengths and a winding drive assembly that can clamp or release any one of the winding drums and drive the winding drums to rotate synchronously after clamping the winding drums. The winding drive assembly includes two first mounting seats that are guided and slide on the operation table, a central positioning and inner support assembly that rotates concentrically on the opposite sides of the two first mounting seats, and a drive mechanism that drives the two first mounting seats to move relatively closer or farther away synchronously. The central positioning and inner support assembly includes a blind cylinder that rotates on the first mounting seat, a telescopic cylinder that elastically expands and contracts along the axial direction of the blind cylinder at the open end of the blind cylinder and is coaxially distributed with the blind cylinder, and a pressing member that protrudes from the outer ring wall of the telescopic cylinder and can be pressed against by the end of the winding drum. At least three inner support units that expand outward synchronously as the telescopic cylinder retracts are circumferentially and evenly spaced on the outer ring wall of the telescopic cylinder at the end away from the blind cylinder. A first drive motor for driving the blind cylinder on one of the first mounting seats to rotate is arranged on one of the first mounting seats.

[0007] By adopting the above scheme, the cloth rolling machine removes the winding roller and is equipped with a plurality of rolls of different lengths and a center positioning inner support assembly. The center positioning inner support assembly can make its telescopic cylinder first inserted into the two ends of the target roll as the two first mounting seats are relatively close to each other, and as the first mounting seats continue to approach, the end of the roll is pressed against the pressing member to achieve the retraction of the telescopic cylinder. As the telescopic cylinder retracts, the inner support unit expands outward. Since the inner support units are distributed at intervals around the circumference of the telescopic cylinder, when the inner support unit is pressed against the inner ring wall of the roll, After that, the reel, telescopic cylinder and blind cylinder can be coaxially distributed. With the rotation of the first drive motor, the reel can be driven to rotate. On the contrary, with the relative distance of the first mounting seat, the telescopic cylinder first extends out relative to the blind cylinder, and the inner support unit retracts inward. When the telescopic cylinder is separated from the reel, the reel with the cloth rolled up automatically separates from the first mounting seat to realize unloading. The spacing between the first mounting seats can be used to adapt to reels of different lengths. Therefore, the cloth rolling machine can adapt to the rolling of cloths of different widths and can realize automatic unloading after rolling.

[0008] Preferably, the internal support unit includes an internal support block and a first lifting arm and a second lifting arm hinged at both ends of the internal support block, the first lifting arm is located at one end of the internal support block away from the pressure piece and the end away from the internal support block is hinged to the telescopic cylinder, the second lifting arm is located at one end of the internal support block close to the pressure piece and the end away from the internal support block is hinged to a moving block, the moving block is guided to move in the telescopic cylinder, and a push rod is fixed at the end of the blind cylinder away from the opening, which presses the moving block as the telescopic cylinder retracts to drive the inner support block to expand outward.

[0009] By adopting the above scheme, the inner support unit is a hinged three-section structure. The above structure can make the middle inner support block float first and then move parallel to the axis of the telescopic cylinder when expanding outward, and then stably press against the inner ring wall of the reel. When in the floating state, the inner support reel can be quickly realized to achieve pre-positioning, and as the moving block continues to move, the end of the floating block that is not in contact with the inner ring wall of the reel continues to expand outward until the floating block is distributed along the axial direction of the reel and presses against the inner ring wall of the reel, thereby realizing the center positioning clamping of the reel.

[0010] Preferably, an elastic member is provided in the blind cylinder between the moving block and the bottom of the blind cylinder to drive the telescopic cylinder to extend outward to a maximum stroke state.

[0011] Preferably, an elastic layer for increasing anti-skid performance is provided on the side of the inner support block facing away from the outer ring wall of the telescopic cylinder, and anti-skid patterns are provided on the surface of the elastic layer.

[0012] With the above solution, the elastic layer and the anti-skid pattern are both used to increase damping, ensuring that the reel and the telescopic cylinder rotate synchronously, that is, the reel and the blind cylinder are in a synchronous rotation state.

[0013] Preferably, the pressing member is a pressing ring that expands outwardly along the radial direction of the telescopic cylinder or a pressing block that protrudes outwardly at uniform intervals around the circumference of the telescopic cylinder.

[0014] Preferably, the blind tube is rotatably arranged on a lifting block which is vertically guided and lifted on the first mounting seat. The lifting of the lifting block is controlled by a lifting drive member which is vertically mounted on the first mounting seat. The lifting rod of the lifting drive member is vertically arranged upward and the end thereof abuts against the bottom of the lifting block.

[0015] With the above scheme, the blind tube rises to the highest state as the lifting rod of the lifting drive extends, and descends with the descent of the lifting rod. The descent stroke depends on the thickness of the rolled cloth. The assembly of the lifting drive can realize the rolled cloth automatically and slowly falling onto the operating table for the operator to pick up.

[0016] Preferably, the feeding mechanism includes two parallel conveying rollers, each of which is rotatably mounted on a group of mounting structures, each group of mounting structures includes two parallel second mounting seats, and one of the second mounting seats in each group of mounting structures is provided with a second drive motor for driving the conveying rollers thereon to rotate.

[0017] By adopting the above solution, as the conveying roller rotates, the cloth can be stably delivered to the winding drive assembly.

[0018] Preferably, the two second mounting seats in each mounting structure group can be synchronously moved closer or farther away from each other, and the conveying roller includes two fixed rollers each having two ends rotatably mounted to a second mounting seat and an adjusting roller simultaneously guided and inserted into the two fixed rollers at both ends.

[0019] By adopting the above solution, when adapting to cloths of different widths, the spacing between the second mounting seats can be adjusted to limit the deviation of the cloth during delivery, and the conveying roller can adaptively change its length as the spacing between the second mounting seats changes.

[0020] Preferably, the relative approach or distance of each group of second mounting seats is synchronously controlled by a driving mechanism, and the bottoms of the first mounting seat and the two second mounting seats located on the same side are synchronously fixed on a driving plate located below the operating table, and the operating table is provided with a clearance groove for the first mounting seat and the second mounting seat to pass through and translate, and the driving mechanism is arranged on the operating table and the two driving plates.

[0021] By adopting the above solution, the second mounting seat and the first mounting seat can adjust the distance synchronously, which can simplify the program control and ensure that the cloth does not deviate during the delivery and winding process.

[0022] Preferably, the driving mechanism includes a forward and reverse screw rod that rotates horizontally under the operating table, two driving plates are located on the two threaded sections of the forward and reverse screw rod with opposite thread directions, a third driving motor that drives the forward and reverse screw rod to rotate is arranged under the operating table, a guide rod parallel to the axis of the conveying roller is fixed under the operating table, and the two driving plates cooperate with the guide rod.

[0023] By adopting the above scheme, the first mounting seat and the second mounting seat are connected together through the driving plate. As the forward and reverse screws rotate, the driving plate moves relatively closer or farther away under the guidance of the guide rod, thereby achieving the relative movement between the first mounting seat and the second mounting seat always being synchronized.

[0024] The present invention has significant technical effects due to the adoption of the above technical scheme: the cloth rolling machine removes the winding roller and is equipped with a plurality of winding drums of different lengths, and is equipped with a center positioning inner support component. The center positioning inner support component can make its telescopic cylinder first inserted into the two ends of the target winding drum as the two first mounting seats are relatively close to each other, and as the first mounting seats continue to approach, the end of the winding drum is pressed against the pressing member to achieve the retraction of the telescopic cylinder. As the telescopic cylinder retracts, the inner support unit expands outward. Since the inner support units are distributed at intervals around the circumference of the telescopic cylinder, when the inner support unit After the element is pressed against the inner ring wall of the reel, the reel, the telescopic cylinder and the blind cylinder can be coaxially distributed. As the first drive motor rotates, the reel can be driven to rotate; conversely, as the first mounting seat moves away from each other, the telescopic cylinder first extends out relative to the blind cylinder, and the inner support unit retracts inward. When the telescopic cylinder is detached from the reel, the reel with the cloth rolled up automatically detaches from the first mounting seat to achieve unloading. The spacing between the first mounting seats can be used to adapt to reels of different lengths. Therefore, the cloth rolling machine can adapt to the rolling of cloths of different widths and can achieve automatic unloading after rolling. BRIEF DESCRIPTION OF THE DRAWINGS
