Description

Technical Field

[0001] This invention relates to the field of textile printing and dyeing fabric taking-up technology, specifically a fabric taking-up device for textile printing and dyeing machinery. Background Technology

[0002] After the textile fabric has been printed, dyed, and dried, it needs to be wound up using a fabric winding device. Existing fabric winding devices, such as the fabric winding device in textile machinery disclosed in CN103922175B, include a frame, F-shaped supports, guide rollers, and spreading rollers. A set of transverse F-shaped supports is fixed on the frame. The two ends of the guide rollers are respectively hinged to the uprights at the front end of the F-shaped supports. Connecting rods are hinged to the uprights in the middle of the F-shaped supports. Positioning posts are fixed to the middle of the connecting rods and the uprights in the middle of the F-shaped supports. The two ends of springs are respectively fixed to the connecting rods and the positioning posts of the F-shaped supports. The two ends of the spreading rollers are respectively hinged to the top of the connecting rods. Branch rods are fixed to the uprights in the middle of the F-shaped supports, and the two ends of the stop rods are respectively fixed to the top of the branch rods. It has a simple structure and low manufacturing cost. During winding, the fabric, under the action of the spreading rollers under tension, effectively eliminates fabric overlap and wrinkles, thereby improving the quality of the wound fabric. In actual use, the existing fabric winding device requires manual disassembly and replacement of the winding rollers when the fabric roll reaches the rated diameter or the fabric length reaches the predetermined value. The overall operation is time-consuming and labor-intensive, with low work efficiency, making it difficult to meet the needs of automated production. Summary of the Invention

[0003] The purpose of this invention is to provide a fabric take-up device for textile printing and dyeing machinery to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a fabric taking-up device for textile printing and dyeing machinery, comprising a frame, a drive mechanism mounted on the frame, a cylinder fixed to the upper rear side of the frame, a drop roller mechanism fixed on the frame, a cutting mechanism mounted on the front side of the frame, and a fabric turning mechanism mounted on the frame on the side of the cutting mechanism. The fabric turning mechanism includes a rotating shaft with bearings connected to the frame, a turning frame fixed on the rotating shaft, two arc-shaped frames symmetrically fixed on the turning frame, and a fabric turning rod connected by bearings between the two arc-shaped frames. The rotating shaft also includes... A drive gear is fixed, which meshes with a movable gear frame. A guide rod is fixed on the movable gear frame, and the guide rod is slidably connected to a fixed plate. The fixed plate is fixed on the frame, and a second spring is fixed between the fixed plate and the movable gear frame. A connecting rod is also connected to the movable gear frame by a bearing, and a torsion spring is fixed between the connecting rod and the movable gear frame. The connecting rod contacts a blocking plate for positioning, and the blocking plate is fixed on the movable gear frame near the arc frame, so that the connecting rod can only rotate in one direction. A convex shaft is also fixed on the connecting rod, and the convex shaft is slidably connected to the inclined plate.

[0005] Preferably, a platform is fixed to the front side of the frame, and a guide roller is also connected to the frame by a bearing. The guide roller can guide the fabric, and the platform can store the take-up roller for the fabric.

[0006] Preferably, the drive mechanism includes a first motor fixed on the frame, and a drive gear is fixed to the output end of the first motor. The drive mechanism also includes a first drive roller and a second drive roller connected to the frame by bearings, and a driven gear is fixed on both the first drive roller and the second drive roller. The driven gear and the drive gear are meshed together. At the same time, the surfaces of the first drive roller and the second drive roller are covered with rough rubber sheets. The first drive roller and the second drive roller contact the take-up roller to achieve transmission. Driven by the first motor, and with the transmission action between the driven gear and the drive gear, the first drive roller and the second drive roller can rotate in the same direction, thereby providing a basic guarantee for driving the take-up roller to rotate and take up the fabric.

[0007] Preferably, the second drive roller is also connected to an arc-shaped pressure plate by a bearing, and a torsion spring is fixed between the arc-shaped pressure plate and the second drive roller. The arc-shaped pressure plates are distributed at equal angles about the center of the second drive roller. Through the action of the arc-shaped pressure plate, pressure can be generated on the fabric to ensure that the fabric is stably wound on the take-up roller and to ensure the normal winding of the fabric.

[0008] Preferably, the output end of the cylinder is fixed with a pusher frame, and the upper end of the pusher frame is fixed with an L-shaped plate. The distance between the L-shaped plate and the lower limit plate is greater than the diameter of the take-up roller. With the above structure, the take-up roller that takes up the fabric can be pushed, thereby realizing the automatic feeding function of the take-up roller.

[0009] Preferably, the dropping roller mechanism includes a bracket fixed on the frame, and a guide plate is fixed on the bracket. The guide plate and the take-up roller are slidably connected. Through the action of the guide plate, the take-up roller can be ensured to move vertically downward.

[0010] Preferably, a mounting plate is provided on the front side of the bracket, and a protruding plate is fixed at the lower end of the mounting plate. The lower end surface of the protruding plate is lower than the upper end surface of the L-shaped plate. At the same time, sliding rods are symmetrically fixed on the mounting plate. The sliding rods are slidably connected to the bracket, and a first spring is fixed between the sliding rods and the bracket. When the mounting plate moves, the sliding guide action between the sliding rods and the bracket can ensure the stability of the movement of the mounting plate. The elastic action of the first spring can provide a basic force for the automatic reset of the mounting plate.

[0011] Preferably, an upper limit plate and a lower limit plate are fixed on the mounting plate, and the distance between the upper limit plate and the lower limit plate is greater than the diameter of the take-up roller. The upper limit plate is provided with a slot for the take-up roller to fall, and the width of the upper limit plate is greater than the width of the lower limit plate. The upper limit plate, the lower limit plate and the guide plate are all slidably connected. Through the cooperation of the upper limit plate and the lower limit plate, the automatic feeding of a single take-up roller can be realized.

[0012] Preferably, the cutting mechanism includes a second motor fixed on the frame, and the output end of the second motor is fixed to a threaded rod connected to the frame by a bearing. The threaded rod is threadedly connected to the movable frame, and the movable frame is slidably connected to the crossbar fixed on the frame. Through the above structure, a basic force can be provided for the movement of the movable frame, thereby providing a basic guarantee for the cutting of the fabric.

[0013] Preferably, a cutting blade is fixed at the upper end of the movable frame at an angle, and a slanted panel is fixed at the lower end of the movable frame. Through the action of the cutting blade, the fabric can be automatically cut, ensuring the normal operation of the device.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This fabric taking-up device for textile printing and dyeing machinery can automatically feed the taking-up roller of the fabric through the action of cylinder and pusher frame. Combined with the cutting action, it can realize the automatic cutting of the fabric. In addition, with the linkage drop roller mechanism, it can realize the automatic feeding of new taking-up roller, thus ensuring the fully automatic replacement of taking-up roller without manual operation. This can effectively reduce the intensity of manual labor and improve work efficiency, thereby better meeting the actual production needs. 2. The fabric take-up device for textile printing and dyeing machinery, through a linked fabric flipping mechanism, can automatically flip the end of the fabric to contact the take-up roller after the fabric is cut by the cutting mechanism. With the help of the arc-shaped pressure plate, pressure is applied to the fabric, so that the fabric can automatically cooperate with the take-up roller to be rolled up, thereby ensuring the normal operation of the device. There is no need for manual winding of the take-up roller and the fabric, which effectively ensures the convenience of the device operation. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-9 The present invention provides a technical solution: a fabric taking-up device for textile printing and dyeing machinery, including a frame 1, a drive mechanism 2 installed on the frame 1, a cylinder 4 fixed at the upper rear end of the frame 1, a drop roller mechanism 5 fixed on the frame 1, a cutting mechanism 6 installed on the front side of the frame 1, and a fabric turning mechanism 7 installed on the frame 1 on the side of the cutting mechanism 6.

[0019] A platform 101 is fixed to the front of the frame 1, and a guide roller 102 is also connected to the frame 1 by bearings. The drive mechanism 2 includes a first motor 201 fixed to the frame 1, and a drive gear 202 is fixed to the output end of the first motor 201. The drive mechanism 2 also includes a first drive roller 203 and a second drive roller 204 connected to the frame 1 by bearings. A driven gear 205 is fixed on both the first drive roller 203 and the second drive roller 204, and the driven gear 205 is meshed with the drive gear 202. At the same time, a rough rubber sheet is pasted on the surface of both the first drive roller 203 and the second drive roller 204. The first drive roller 203 and the second drive roller 204 contact the take-up roller 3 to realize transmission. An arc-shaped pressure plate 206 is also connected to the second drive roller 204 by bearings, and a torsion spring is fixed between the arc-shaped pressure plate 206 and the second drive roller 204. The arc-shaped pressure plate 206 is distributed at equal angles with respect to the center of the second drive roller 204. When using the fabric take-up device for textile printing and dyeing machinery, such as Figures 1-9 As shown, firstly, the fabric to be rolled up is passed around the guide roller 102 and through the gap between the first drive roller 203 and the second drive roller 204. Then, the fabric is wrapped around the take-up roller 3 on the first drive roller 203 and the second drive roller 204 several times to complete the preparation work. When rolling up the fabric, simply start the first motor 201 to drive the drive gear 202 to rotate counterclockwise. With the transmission between the drive gear 202 and the driven gear 205, the first drive roller 203 and the second drive roller 204 rotate clockwise synchronously. With the friction between the rough rubber sheet on the upper surface of the first drive roller 203 and the second drive roller 204 and the fabric on the take-up roller 3, the take-up roller 3 can rotate counterclockwise, thereby realizing the roll-up of the fabric. A pusher frame 401 is fixed to the output end of cylinder 4, and an L-shaped plate 402 is fixed to the upper end of the pusher frame 401. The distance between the L-shaped plate 402 and the lower limit plate 508 is greater than the diameter of the take-up roller 3. The drop roller mechanism 5 includes a bracket 501 fixed to the frame 1, and a guide plate 502 is fixed on the bracket 501. The guide plate 502 and the take-up roller 3 are slidably connected. A mounting plate 503 is provided on the front side of the bracket 501, and a protruding plate 504 is fixed to the lower end of the mounting plate 503. The lower end surface of the protruding plate 504 is lower than the upper end surface of the L-shaped plate 402. At the same time, the mounting plate 503 also has A sliding rod 505 is fixed symmetrically on the left and right sides. The sliding rod 505 is slidably connected to the bracket 501, and a first spring 506 is fixed between the sliding rod 505 and the bracket 501. An upper limit plate 507 and a lower limit plate 508 are fixed on the mounting plate 503. The distance between the upper limit plate 507 and the lower limit plate 508 is greater than the diameter of the take-up roller 3. The upper limit plate 507 is provided with a slot for the take-up roller 3 to fall. At the same time, the width of the upper limit plate 507 is greater than the width of the lower limit plate 508. The upper limit plate 507, the lower limit plate 508 and the guide plate 502 are all slidably connected. During the fabric winding process, such as Figures 1-9As shown, when the fabric on the take-up roller 3 needs to be replaced after being wound to a preset length, the first motor 201 stops rotating and the cylinder 4 starts to extend. The extension of the cylinder 4 drives the pusher frame 401 forward. When the pusher frame 401 contacts the fabric on the take-up roller 3, it exerts a force on the take-up roller 3, causing it to move forward. This separates the take-up roller 3 from the first drive roller 203 and the second drive roller 204, and it rolls onto the platform 101, thus achieving automatic unloading of the take-up roller 3. Simultaneously, as the pusher frame 401 moves forward, it also drives the L-shaped plate 402 forward. When the L-shaped plate 402 contacts the convex plate 504 and exerts a force, the mounting plate 503, the upper limit plate 507, and the lower limit plate 508 move forward under pressure. Combined with the sliding guide action between the slide rod 505 and the bracket 501, this ensures that the mounting plate 503, the upper limit plate 507, and the lower limit plate 508 move forward. 08. For the stability of movement, when the lower limit plate 508 separates from the bottommost take-up roller 3 of the guide plate 502, the upper limit plate 507 contacts the second bottommost take-up roller 3 of the guide plate 502 to achieve positioning. This allows the bottommost take-up roller 3 of the guide plate 502 to automatically fall onto the first drive roller 203 and the second drive roller 204 under the action of gravity, thereby realizing the automatic replacement of the new take-up roller 3. When the cylinder 4 retracts and resets, the first spring 506 can automatically reset the mounting plate 503, the upper limit plate 507, and the lower limit plate 508. When the upper limit plate 507 and the lower limit plate 508 have finished resetting, the lower limit plate 508 blocks the gap between the guide plates 502. At this time, the slot on the upper limit plate 507 is exactly matched with the second bottommost take-up roller 3 of the guide plate 502, so that the second take-up roller 3 falls onto the lower limit plate 508 for the next replacement. The cutting mechanism 6 includes a second motor 601 fixed on the frame 1, and the output end of the second motor 601 is fixed to a threaded rod 602 connected to the frame 1 by a bearing. The threaded rod 602 is threadedly connected to the movable frame 603, and the movable frame 603 is slidably connected to the crossbar 604 fixed on the frame 1. A cutting blade 605 is obliquely fixed at the upper end of the movable frame 603, and an oblique panel 606 is fixed at the lower end of the movable frame 603. After cylinder 4 has retracted and reset, as follows: Figures 1-9 As shown, at this time, the second motor 601 starts and drives the threaded rod 602 to rotate. With the threaded connection between the threaded rod 602 and the movable frame 603, the movable frame 603 moves from left to right. With the sliding guide between the movable frame 603 and the crossbar 604, the stability of the movement of the movable frame 603 can be ensured. When the movable frame 603 moves, the cutting blade 605 moves synchronously. When the cutting blade 605 contacts the fabric, the automatic cutting of the fabric can be realized. When the cutting blade 605 moves to the rightmost side, the cutting of the fabric is completed. The fabric turning mechanism 7 includes a rotating shaft 701 connected to the frame 1 by bearings. A turning frame 702 is fixed on the rotating shaft 701. Two arc-shaped frames 703 are symmetrically fixed on the turning frame 702, and a fabric turning rod 704 is connected between the two arc-shaped frames 703 by bearings. A drive gear 705 is also fixed on the rotating shaft 701. The drive gear 705 meshes with a movable gear frame 706. A guide rod 707 is fixed on the movable gear frame 706. The guide rod 707 is slidably connected to a fixed plate 708. The fixed plate 708 is fixed to the frame 1. A second spring 709 is fixed between the fixed plate 708 and the movable gear frame 706. A connecting rod 710 is also connected to the movable gear frame 706 by a bearing. A torsion spring is fixed between the connecting rod 710 and the movable gear frame 706. The connecting rod 710 contacts the blocking plate 711 to achieve positioning. The blocking plate 711 is fixed on the side of the movable gear frame 706 near the arc frame 703, so that the connecting rod 710 can only rotate in one direction. A convex shaft 712 is also fixed on the connecting rod 710. The convex shaft 712 is slidably connected to the inclined plate 606. When the movable frame 603 moves from left to right, such as Figures 1-9As shown, the movement of the movable frame 603 can synchronously drive the inclined panel 606 to move. When the inclined panel 606 exerts a force on the left convex shaft 712, the connecting rod 710 rotates under force. At this time, the connecting rod 710 does not move back and forth. When the inclined panel 606 moves to contact the right convex shaft 712, the cutting blade 605 has completed the cutting of the fabric, and the cut fabric automatically falls onto the fabric flipping rod 704. When the inclined panel 606 exerts a force on the right convex shaft 712, the connecting rod 710 cannot rotate due to the blocking effect of the blocking plate 711. When the right-side convex shaft 712 slides against the inclined surface of the inclined plate 606, the connecting rod 710 is forced to move forward, thereby driving the movable gear frame 706 forward. Combined with the sliding guidance between the guide rod 707 and the fixed plate 708, the stability of the movable gear frame 706's movement is ensured. During the movement of the movable gear frame 706, the meshing transmission between the movable gear frame 706 and the drive gear 705 causes the rotating shaft 701 to rotate counterclockwise, thus synchronously driving the flipping frame 702, the arc frame 703, and the fabric flipping rod 704 forward. The fabric is rotated, and the fabric flipping rod 704 rotates, flipping the fabric falling on the flipping rod 704 backward. When the movable frame 603 and the inclined plate 606 move to the rightmost position, the right convex shaft 712 separates from the inclined plate 606. With the elastic action of the second spring 709, the flipping frame 702, the arc frame 703, and the fabric flipping rod 704 can be reset for the next flipping. After the fabric is flipped, it covers the upper surface of the new take-up roller 3, and the end of the fabric is in contact with the second drive roller 204 and the arc pressure plate 206. The first motor 2 is then restarted. 01 causes the first drive roller 203 and the second drive roller 204 to rotate clockwise, which in turn drives the new take-up roller 3 to rotate. With the elastic action of the arc-shaped pressure plate 206 and the torsion spring, a certain pressure can be applied to the end of the fabric, so that the end of the fabric can be put into contact with the new take-up roller 3 under the action of the arc-shaped pressure plate 206. With the rotation of the new take-up roller 3, the new take-up roller 3 can re-wrap the fabric, thereby realizing the automatic replacement of the take-up roller 3 without manual intervention, which better meets the needs of automated production. This is the working principle of the take-up device for textile printing and dyeing machinery.
