Description

Technical Field

[0001] This invention relates to fabric winding equipment, and particularly to a fully automatic winding and sealing integrated machine. Background Technology

[0002] Circular knitting machines are core equipment in the production of knitted fabrics. The tubular fabrics produced by these machines require subsequent winding and straightening operations, which is a crucial step in the fabric forming process. The core working principle of existing fabric winding and straightening machines is as follows: First, the tubular knitted fabric woven by the circular knitting machine is automatically wound open and flattened to open and flatten the fabric, eliminating wrinkles and tubular structures, resulting in a flat sheet structure. Then, through roller drive and tension adjustment, the flattened fabric is continuously wound up, ultimately forming a regular cylindrical roll, completing the fabric setting and winding process.

[0003] In the existing production process, the fabric rolls formed by the open-width winding machine need to be processed in a multi-stage step-by-step manner to complete the final packaging process. The specific process is as follows: after the fabric roll is formed, it is first ejected from the winding station of the open-width winding machine by the equipment ejection mechanism; then, the formed fabric roll is transported to a designated storage area for temporary storage by manual labor or handling equipment; after a certain number of fabric rolls have been accumulated, a second transfer is carried out, and the stored fabric rolls are uniformly transported to a dedicated packaging station to complete the subsequent sealing operation, and finally the finished fabric roll is obtained.

[0004] The aforementioned traditional processing techniques have numerous defects and shortcomings in actual production applications. First, the fabric processing from initial unwinding to final packaging involves multiple independent steps, including winding, unwinding, storage, secondary handling, and packaging. These steps are cumbersome and fragmented, with significant waiting and transfer time between each step, making continuous, integrated operation impossible. This drastically reduces the overall fabric processing efficiency and hinders the automation and high-efficiency production requirements of knitted fabric production lines. Second, the fabric rolls undergo multiple handling, loading, unloading, and storage transfers. During these repeated transfers and placements, the outer fabric layer is easily subjected to friction, impacts, and compression from equipment, the ground, and tooling, leading to pilling, scratches, wrinkles, and damage, thus compromising the fabric's appearance and performance.

[0005] In summary, the current operational mode of separating fabric opening, winding, and packaging processes, and involving multi-stage transfers, suffers from core problems such as low production efficiency, cumbersome procedures, easy fabric damage, and poor product quality stability, making it difficult to meet the demands of large-scale, high-quality, and high-efficiency production of modern knitted fabrics. To overcome the numerous shortcomings of existing technologies, improve the integration and production efficiency of fabric winding, sealing, and packaging processes, and reduce fabric waste, this paper proposes an integrated winding and sealing machine.

[0014] A further improvement is made to the automatic roll changing mechanism, which includes a core supply track, a fabric turning roller, and fabric turning arms. The core supply track is located on the left and right side walls of the frame above the fabric rolling roller assembly. The two ends of the outer core extend into the core supply track on the left and right sides, respectively. The outlet of the core supply track is located directly above the fabric rolling groove of the fabric rolling roller assembly. The fabric turning arms are respectively sleeved on the left and right ends of the fabric rolling roller located behind the fabric rolling groove. The two ends of the fabric turning roller are located at the free ends of the fabric turning arms on the left and right sides. The frame is equipped with a fabric turning drive device that drives the fabric turning arms to flip and press the fabric ends onto the surface of the new core, and a release device that releases the cores one by one as they fall into the fabric rolling groove.

[0015] A further improvement is made to the fabric turning drive device, which includes a fabric turning piston cylinder, a rack, a fabric turning gear, and a clearance gear. The fabric turning piston cylinder is located below the fabric rolling roller assembly and is fixed to the frame in the front-to-back direction. One end of the rack is fixedly connected to the piston rod of the fabric turning piston cylinder. The frame is provided with a rack guide device to guide the rack to slide linearly. The fabric turning gear is rotatably sleeved on the end of the fabric rolling roller and fixedly connected to the fabric turning arm. The clearance gear is rotatably disposed on the frame between the fabric turning gear and the rack, and the clearance gear meshes with the fabric turning gear and the rack for transmission.

[0016] A further improvement is that the rack and pinion guide device includes a guide rail and a guide slider. The guide rail is fixed to the frame, the guide slider is slidably sleeved on the guide rail, and the rack is fixed on the guide slider.

[0017] A further improvement is that the core supply track includes an upper plate, a lower plate, and a side plate; the side plates are respectively fixedly disposed on the left and right sides of the frame, the upper section of the side plate is inclined upward, the upper plate and the lower plate are respectively fixed to the upper edge and the lower edge of the side plate, and a horizontally open sliding channel is formed between the upper plate, the lower plate and the side plate.

[0018] A further improvement is made to the release device, which includes a release opening, a swing block, a first insert block, a second insert block, a guide block, and a release piston cylinder. The release opening is located at the rear end of the upper plate. The guide block is fixed to the frame above the release opening. The swing block is rotatably mounted on the frame above the guide block. The upper end of the first insert block is hinged to the front end of the swing block, and the upper end of the second insert block is hinged to the rear end of the swing block. The distances from the two hinge axes to the rotation center line are equal. The guide block has a guide channel that guides the first and second insert blocks to slide vertically through the release opening and into the sliding channel. The release piston cylinder is fixed to the frame in the front-rear direction. The piston rod of the release piston cylinder is hinged to the swing block, and the piston rod drives the first and second insert blocks to alternately extend into the sliding channel.

[0019] A further improvement is that the discharge section of the sliding channel is a vertical guide section that guides the core to fall vertically.

[0020] A further improvement is that the upper section of the lower plate extends upward and is folded and fixed to the side plate, the upper section of the upper plate is shorter than the upper section of the side plate, and the upper ends of the upper plate, lower plate and side plate form an upward-facing core feeding inlet.

[0021] A further improvement is that: receiving blocks are provided on the frame on both sides of the fabric roll groove to receive the roll core and restrict its forward and backward movement; the receiving blocks slide up and down on the frame; the receiving blocks have a limiting groove from the top to the bottom for the roll core to enter; the receiving blocks are provided with a locking device to prevent the roll core from detaching from the receiving blocks upward; and the frame is provided with a lifting drive device to drive the receiving blocks to slide up and down.

[0022] A further improvement is that the locking device is a locking piston cylinder, the housing of which is fixed to the receiving block along the direction perpendicular to the core, and the receiving block has a locking channel that connects to the limiting groove. The piston rod of the locking piston cylinder passes through the locking channel. The piston rod of the locking piston cylinder extends out to close the limiting groove opening and retracts to release the limiting groove opening.

[0023] A further improvement is made to the lifting drive device, which includes a lifting guide rail, a lifting slider, a first lifting gear, a second lifting gear, a lifting gear chain, and a lifting reduction motor. The lifting guide rail is longitudinally mounted on the frame on one side of the receiving block. The lifting slider is slidably sleeved on the lifting guide rail. The first and second lifting gears are rotatably mounted on the frame at the upper and lower ends of the lifting guide rail. The lifting gear chain is wound around the first and second lifting gears and is fixedly connected to the lifting slider. The lifting reduction motor is fixedly mounted on the frame, and its output shaft is drivenly connected to either the first or second lifting gear.

[0024] A further improvement is that: a plug-in piston cylinder is fixedly installed on the lifting slider, a plug-in block is fixedly installed on the piston rod of the plug-in piston cylinder, a plug-in rod is fixedly installed on the receiving block, and a plug-in groove is horizontally opened on the plug-in block for the plug-in rod to slide horizontally into.

[0025] By adopting the aforementioned technical solution, the beneficial effects of the present invention are: 1. The frame serves as the main support for the entire machine, uniformly supporting the fabric roll assembly, ejector device, cutting device, and automatic roll changing mechanism. The two rollers of the fabric roll assembly form a roll groove to continuously complete the fabric roll-up. After the fabric roll is formed, the ejector device pushes the fabric roll outward, the cutting device cuts the fabric simultaneously, and the automatic roll changing mechanism automatically completes the replenishment of the roll core and its contact with the fabric end. The conveyor rail is arranged vertically to the fabric roll mechanism, providing a linear sliding track for the roll receiving mechanism, realizing the continuous transfer of the fabric roll from the roll-up station to the sealing station.

[0026] In the coiling mechanism, the sliding seat is driven by the conveyor drive device to reciprocate along the conveyor rail. The mounting plate is fixed at both ends of the sliding seat to provide installation support for the coiling arms and positioning baffles. The two upwardly inclined coiling arms form a receiving surface to receive the formed fabric roll. The coiling roller is mounted on the free ends of the two coiling arms, which not only enhances the synchronization and structural stability of the coiling arms and reduces the friction of the fabric roll receiving, but also allows the coiling arms to be as close as possible to the fabric roll assembly. Even if the coiling roller contacts the fabric roll assembly, it can rotate accordingly without interfering with normal fabric rolling, allowing the coiling arms to be in position in advance. The positioning baffle prevents the fabric roll from sliding backward. The flipping device can simultaneously drive the coiling arms and positioning baffles to flip and unload the material.

[0027] The winding mechanism on the sliding seat gathers the loose ends of the fabric roll during transport, making the roll compact and neat. The conveying drive device uses screw transmission to precisely control the start and stop of the sliding seat and the conveying distance, ensuring smooth and vibration-free transport. Two sealing slide rails are symmetrically arranged at the rear end of the conveyor rail. The sliding drive device drives the sealing seat to slide left and right along the sealing slide rails to adapt to fabric rolls of different widths. The sealing seat and the longitudinally installed sealing disc have a through sealing channel for the fabric roll to pass through. The sealing rod on the sealing disc can load the sealing film roll. The sealing drive device uses friction transmission to drive the sealing disc to rotate at a constant speed to complete the film coating. The entire mechanism integrates the winding, transporting, winding, and sealing processes, eliminating the need for manual handling and storage of fabric rolls, reducing fabric bumps and scratches, and achieving continuous automated production.

[0028] 2. Two winding rollers are installed on the mounting plate of the sliding seat to form a winding groove. When the formed fabric roll is transferred, it falls into the winding groove. The matching rotation drive device drives the two winding rollers to rotate synchronously, which drives the fabric roll to roll and gather the fabric tail section that is drooping after cutting, eliminating the problem of loose and curled edges of the fabric roll, avoiding film wrinkles and incomplete coverage when sealing the roll, and improving the flatness of the finished packaging appearance.

[0029] 3. The output torque of the rotating reduction motor drives the first gear to rotate. The second and third gears at the ends of the two winding rollers are synchronously linked by the gear chain to achieve complete synchronization of the rotation speed of the two winding rollers. The transmission structure is stable and the power distribution is uniform, preventing the single winding roller from pulling the fabric too fast and ensuring a uniform winding and gathering effect.

[0030] 4. The rotating shaft is fixed on the mounting plates on both sides. The receiving arm and the tilting arm are synchronously sleeved on the rotating shaft and fixed as one piece. The piston cylinder pushes and pulls the tilting arm to rotate around the rotating shaft, which can synchronously drive the receiving arm and the positioning baffle to tilt and complete the unloading. A limit unloading rod is added above the mounting plate. When the cloth roll falls and impacts the receiving arm, it shares the instantaneous load and avoids the impact being entirely applied to the piston cylinder. It buffers and protects the cylinder body, tilting arm and other stress-bearing parts, extends the service life of the tilting device and reduces the frequency of equipment maintenance.

[0031] 5. The conveyor geared motor drives the first lead screw to rotate continuously. The lead screw meshes with the first lead screw nut to convert the rotational motion into linear displacement, which drives the sliding seat to smoothly convey the fabric roll along the conveyor rail. The lead screw transmission has high positioning accuracy and strong load-bearing capacity. It can accurately control the start and stop of the roll receiving mechanism and the conveying stroke. There is no impact or shaking during the transfer process, which ensures the stability of the fabric roll posture and provides a precise positioning basis for subsequent roll sorting and sealing.

[0032] 6. Multiple rollers are arranged around the outer periphery of the sealing reel. Positioning and rotating grooves are opened on the outer wall of the rollers to engage and limit the sealing reel. The sealing reel reduction motor drives the rotation of a single roller. The friction between the roller and the groove wall of the sealing reel drives the entire sealing reel to rotate at a uniform speed. The friction transmission speed is stable and the film tension is constant. During lamination, there will be no film stretching and breaking, stacking and wrinkling. It can completely and evenly cover the outer periphery and end faces of the fabric roll.

[0033] 7. The sliding reduction motor drives the second lead screw to rotate. The second lead screw, together with the second lead screw nut, drives the sealing roll seat to slide towards or away from each other along the sealing roll slide rail. The lead screw transmission has high adjustment accuracy and can accurately control the closing distance of the sealing roll seats on both sides according to the width of the fabric roll. It is suitable for various specifications of fabric rolls, avoids film tearing and damage during lamination, and improves the versatility of the equipment.

[0034] 8. The core supply track is installed on both sides of the frame above the fabric roll assembly, which can store cores in batches. The discharge port is directly opposite the fabric roll groove. The release device enables the cores to fall into the fabric roll groove one by one. The fabric turning arm is fitted at both ends of the fabric roll, and the fabric turning roller is mounted on the free end of the fabric turning arm. The fabric turning drive device drives the fabric turning arm to press down. The fabric turning roller presses the fabric end tightly against the newly dropped core. There is no need for manual fabric bonding. The winding and winding start is completed automatically. The whole mechanism continuously supplies cores and bonds fabric, realizing automatic roll changing without downtime, eliminating waiting time for roll changing, and improving the continuity of winding.

[0035] 9. The fabric-turning piston cylinder pushes and pulls the rack back and forth. The rack is driven to the fabric-turning gear through the meshing of the avoidance gear, which in turn drives the fabric-turning arm to flip and press down. The avoidance gear is staggered to avoid the arrangement path of the fabric roll group, making the whole machine structure more compact. The rack guide device constrains the rack to slide in a straight line, so there is no deviation or jamming in the transmission. The downward pressure of the fabric-turning roller is uniform, and the fabric end is firmly bonded to the roll core, so there will be no problems such as delamination at the beginning or uneven roll shape.

[0036] 10. The guide rail is fixed to the frame, the guide slider is slidably mounted on the outside of the rail, and the rack is fixed on the guide slider. The cooperation between the rail and the slider restricts the rack to move only in a straight line back and forth, eliminating transmission jamming caused by rack swing and offset, and ensuring stable fabric turning action and accurate positioning.

[0037] 11. The side plates are fixed to the left and right side walls of the frame. The upper section is inclined to prevent the core from rolling off on its own. The upper plate and lower plate are fixed to the upper and lower edges of the side plates respectively. The three together form a horizontal sliding channel, which can store multiple cores at one time for later use, realize batch replenishment of cores, and reduce frequent manual feeding operations.

[0038] 12. The side plates are fixed to the left and right side walls of the frame. The upper section is inclined to prevent the core from rolling off on its own. The upper plate and lower plate are fixed to the upper and lower edges of the side plates respectively. The three together form a horizontal sliding channel, which can store multiple cores at one time for later use, realize batch replenishment of cores, and reduce frequent manual feeding operations.

[0039] 13. The material discharge section of the sliding channel is equipped with a vertical guide section. After the core is released from the sliding channel, it falls vertically along the vertical guide section and is accurately aligned with the fabric rolling groove below. This prevents the core from falling crookedly, tipping over, or getting stuck, and ensures that the core falls smoothly to the winding station.

[0040] 14. The upper part of the lower plate is folded upward to fix the side plate, and the upper part of the upper plate is shorter than the upper part of the side plate. The upper ends of the three are joined together to form an upward-facing core replenishment inlet. Operators can put cores in batches from above. The inlet enclosure structure can prevent cores from falling out from above the sliding channel, making core storage more stable and maximizing the use of the sliding channel for core storage.

[0041] 15. The receiving blocks on both sides of the fabric roll groove can slide up and down and have limiting grooves to receive the falling roll core. The limiting grooves restrict the roll core from moving back and forth. The matching locking device locks the roll core to prevent it from jumping up during winding. The lifting drive device drives the receiving blocks to lift and lower, completing the roll core receiving and winding station positioning. During the winding process, the roll core does not deviate or shake. The formed fabric roll has a regular cylindricity, improving the quality of fabric winding.

[0042] 16. The locking piston cylinder is installed vertically on the receiving block. The piston rod passes through the locking channel of the connecting limiting groove. The piston rod extends out of the closed limiting groove to lock the core. After winding is completed, the piston rod retracts to unlock and release the core. The locking and releasing of the core is completed automatically. No manual limit is required throughout the process, which avoids the core from jumping or shifting.

[0043] 17. The lifting slider is equipped with a plug-in piston cylinder. The piston rod drives the plug-in block to extend and retract horizontally. The plug-in slot of the plug-in block is engaged with the plug-in rod on the receiving block. During the core receiving and lifting stages, the plug-in locking provides power to the receiving block and improves the overall rigidity of the receiving block. During the fabric winding stage, the plug-in structure separates, releasing the moving allowance of the receiving block, offsetting the winding tension, reducing the fatigue of the lifting drive device, extending its service life, and balancing structural strength and operational flexibility.

The upper ends of the upper plate 57, lower plate 58 and side plate 59 form an upward-opening core supply inlet 68 to prevent the core from falling out of the sliding channel.

[0068] On the left and right sides of the frame 10 of the fabric roll groove 14, there are receiving blocks 69 that receive the roll core and restrict the front and back movement of the roll core. The receiving blocks 69 are slidably disposed on the frame 10. The receiving blocks 69 have a limiting groove 70 for the roll core end to fall into from the upper end. The receiving blocks 69 are provided with a locking device to prevent the roll core from detaching from the receiving blocks 69. The frame 10 is provided with a lifting drive device to drive the receiving blocks 69 to slide up and down.

[0069] The locking device is a locking piston cylinder 71. The housing of the locking piston cylinder 71 is fixed to the receiving block 69 along the direction perpendicular to the core. The receiving block 69 has a locking channel that connects to the limiting groove 70. The piston rod of the locking piston cylinder 71 passes through the locking channel. The piston rod of the locking piston cylinder 71 extends out of the opening of the closing limiting groove 70 and retracts to release the opening of the limiting groove 70.

[0070] The lifting drive device includes a lifting guide rail 72, a lifting slider 73, a first lifting gear 74, a second lifting gear 75, a lifting gear chain (not shown in the figure), and a lifting reduction motor (not shown in the figure). The lifting guide rail 72 is longitudinally arranged on the frame 10 on one side of the receiving block 69. The lifting slider 73 is slidably sleeved on the lifting guide rail 72. The first lifting gear 74 and the second lifting gear 75 are rotatably arranged on the frame 10 at the upper and lower ends of the lifting guide rail 72. The lifting gear chain is wound around the first lifting gear 74 and the second lifting gear 75. The lifting gear chain is fixedly connected to the lifting slider 73. The lifting reduction motor is fixedly arranged on the frame 10. The output shaft of the lifting reduction motor is fixedly connected to the first lifting gear 74 or the second lifting gear 75.

[0071] A connecting piston cylinder 76 is fixedly mounted on the lifting slider 73. A connecting block 77 is fixedly mounted on the piston rod of the connecting piston cylinder 76. A connecting rod 78 is fixedly mounted on the receiving block 69. A connecting groove 79 is horizontally opened on the connecting block 77 for the connecting rod 78 to slide horizontally into. When the core winds up the fabric, the connecting block separates from the connecting groove.

[0072] The working process of a fully automatic winding and sealing machine: The operator first inserts the core into the sliding channel through the replenishment inlet at the top of the core supply track 48. The piston cylinder 67 is then released to drive the swing block 63 to reciprocate, causing the first insert block 64 and the second insert block 65 to extend and retract alternately, lowering only one core at a time. The lifting drive device drives the receiving block 69 to rise and receive the core. After the core falls into the limiting groove 70 of the receiving block 69, the locking piston cylinder 71 extends to lock the core. The lifting drive device then drives the receiving block 69 to fall to the winding position to complete the material preparation. Subsequently, the fabric-turning piston cylinder 51 pushes the rack 52, which, through the avoidance gear 54, drives the fabric-turning arm 50 to rotate. The fabric-turning roller 49 presses down to press the fabric end tightly against the surface of the new core. The winding roller group 11 then rotates, continuously winding the core around the fabric. After the winding is stable, the fabric-turning roller 49 returns to its original position. Once the fabric roll reaches the set specifications, the locking piston cylinder 71 retracts and unlocks, the lifting drive device lowers the receiving block 69, and the ejector device 12 pushes the formed fabric roll to the receiving surface of the receiving arm 18. The positioning baffle 19 holds the fabric roll to prevent it from rolling off. Then, the cutting device 13 slides left and right to cut the fabric. If the resulting falling section of the fabric is too long, it can be retracted slightly in the opposite direction. The next roll core falls to await material, and the above actions are repeated.

[0073] The conveyor geared motor 39 drives the first lead screw 40 to move the sliding seat 16 carrying the fabric roll along the conveyor rail 15 towards the sealing station. Before or during transfer, the rotating geared motor 30 on the sliding seat 16 synchronously drives the two winding rollers 27 to rotate via a gear chain. The fabric roll rolls in the winding groove 28 to gather the loose tail of the fabric. The sliding seat 16 stops moving after reaching the end of the conveyor rail 15. The sliding geared motor 45 drives the second lead screw 46 to move the two sealing seats 23 to close towards each other along the sealing slide rail 22. When the end of the fabric roll extends into the sealing channel 25, the film is first wound around the fabric roll by the operator. Then, the sealing geared motor 43 drives the outer peripheral roller 42 to rotate the sealing disc 24 as a whole by friction, releasing the packaging film to completely cover the fabric roll. The sealing seat 23 slides closer to the center of the fabric roll, and the film covers the end of the fabric roll. After the covering is completed, the film is cut off by the operator, and the sealing seat 23 returns to its original position. The piston cylinder of the flipping device extends to push the flipping arm 36 and the receiving arm 18 to flip upward together, tilting out the sealed fabric roll. Repeating the above process, continuous automated winding and sealing cycle production is achieved.
