Description

Technical Field

[0001] This utility model relates to the field of printing equipment, and more specifically, it relates to a winding device for printing. Background Technology

[0002] Printed fabric is a process in which dyes or pigments are printed onto textiles to create patterns with a certain degree of colorfastness. Using a paste as the dyeing medium, dyes or pigments are mixed into printing paste and printed onto the fabric. After drying, the fabric undergoes subsequent treatments such as steaming and color development, depending on the properties of the dyes or colors, so that the dyes are attached to the fibers. After the printed fabric is finished, it is usually wound up using a winding device.

[0003] Existing winding devices typically consist of a single winding roller, which is driven by a motor to rotate and wind up the fabric. Once the winding roller is fully wound with fabric, it needs to be removed and a new winding roller needs to be installed on the winding device for winding. This process requires stopping the winding operation, which leads to a decrease in the overall efficiency of fabric winding.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a winding device for printing.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a winding device for printing, including a winding frame and a guide roller. The winding frame has a U-shaped cross-section. The guide roller is rotatably connected to the inner side wall of the winding frame. A horizontally arranged turntable is rotatably mounted on the inner bottom wall of the winding frame. Four L-shaped mounting blocks are fixedly connected to the top surface of the turntable. Two of the horizontal parts of the mounting blocks are rotatably connected to winding rollers via motors. The number of winding rollers is two, and the axial directions of the two winding rollers are relatively parallel. The output end of the motor is fixedly mounted to the end of the winding roller near the motor via a connector. The horizontal part of the mounting block is provided with a clamping component for clamping the end of the winding roller.

[0007] Preferably, a vertically arranged hydraulic rod is fixedly connected to the inner bottom wall of the winding frame. The top end of the hydraulic rod is a telescopic end, and a mounting plate is fixedly connected to the telescopic end of the hydraulic rod. The turntable is rotatably connected to the top surface of the mounting plate via a rotating shaft. The bottom end of the rotating shaft is rotatably mounted on the top surface of the mounting plate. A limit component is provided between the mounting plate and the rotating shaft.

[0008] Preferably, the limiting component includes a ratchet and a pawl. The ratchet is fixedly connected to the outer peripheral wall of the rotating shaft and the two are coaxially arranged. The pawl is rotatably connected to the top surface of the mounting plate. A leaf spring is provided on the top surface of the mounting plate. The leaf spring abuts against one side of the pawl so that the pawl and the ratchet are engaged.

[0009] Preferably, the connecting component includes a flange, which is fixedly connected to the output end of the motor and the end of the take-up roller near the motor, respectively. The flanges of the motor and the take-up roller are correspondingly arranged, and the corresponding flanges are fixedly installed by bolts.

[0010] Preferably, the clamping assembly includes a lower clamping block and an upper clamping plate rotatably connected to the top of the lower clamping block. The bottom of the lower clamping block is fixedly connected to the horizontal part of the mounting block. The lower clamping block and the upper clamping plate are both provided with grooves for accommodating the end of the take-up roller on their respective sides. The upper clamping plate and the lower clamping block are fixedly installed by screws.

[0011] In summary, this utility model has the following beneficial effects: This solution has a horizontally arranged turntable mounted inside the winding frame, and two winding rollers are mounted on the turntable via a motor. When the printed fabric is finished and being wound, the fabric is first fed to the guide roller and then wound around the surface of one of the winding rollers. The motor drives the winding roller to rotate, thus winding the fabric. After one winding roller finishes winding the fabric, the turntable rotates, causing both winding rollers to rotate, bringing the unused winding roller closer to the guide roller for winding the next roll of fabric. While the unused winding roller is winding the fabric, the winding roller that has finished winding can be removed from the mounting block on the turntable via a connector for replacement with a new winding roller. This allows for the simultaneous removal of one winding roller that has finished winding the fabric and the use of the other winding roller to wind a new roll of fabric, thereby improving the fabric winding efficiency.

Detailed Implementation

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] Example:

[0018] A printing winding device, such as Figures 1 to 3 As shown, the device includes a take-up frame 1 and a guide roller 2. The take-up frame 1 has a U-shaped cross-section. The guide roller 2 is rotatably connected to the inner wall of the take-up frame 1 via a geared motor 5. The geared motor 5 is mounted on the outer wall of the take-up frame 1 via mounting bolts. A horizontally positioned turntable 3 is rotatably mounted on the inner bottom wall of the take-up frame 1. Four L-shaped mounting blocks 4 are welded to the top surface of the turntable 3. The vertical parts of the mounting blocks 4 are welded to the turntable 3. Two of the horizontal parts of the mounting blocks 4 are rotatably connected to take-up rollers 6 via motors 5. The motors 5 are mounted on the horizontal parts of the mounting blocks 4 via fastening bolts. There are two motors 5 and two take-up rollers 6, and the axial directions of the two take-up rollers 6 are relatively parallel. One take-up roller 6 is correspondingly positioned with two mounting blocks 4, and the motor 5 is correspondingly positioned with the take-up roller 6. The output end of the motor 5 is fixedly mounted to the end of the take-up roller 6 closest to the motor 5 via a connector. A clamping assembly 7 for clamping the end of the take-up roller 6 is mounted on the horizontal part of the mounting block 4. The number of holding components 7 and mounting blocks 4 are both four. A vertically arranged hydraulic rod 8 is welded to the inner bottom wall of the winding frame 1. The top of the hydraulic rod 8 is a telescopic end. The end of the hydraulic rod 8 furthest from the telescopic end is mounted on the inner bottom wall of the winding frame 1 by screws. A mounting plate 9 is welded to the telescopic end of the hydraulic rod 8. The turntable 3 is rotatably connected to the top surface of the mounting plate 9 via a rotating shaft 10. The bottom end of the rotating shaft 10 is rotatably mounted on the top surface of the mounting plate 9, and the top end of the rotating shaft 10 is welded to the bottom surface of the turntable 3. A limiting component 11 is installed between the disk 9 and the rotating shaft 10. The limiting component 11 includes a ratchet 111 and a pawl 112. The ratchet 111 is welded to the outer peripheral wall of the rotating shaft 10 and the two are coaxially arranged. The pawl 112 is rotatably connected to the top surface of the mounting disk 9 through the rotating shaft. A leaf spring 12 is installed on the top surface of the mounting disk 9. One side of the leaf spring 12 is partially bonded to the top surface of the mounting disk 9. The leaf spring 12 abuts against one side of the pawl 112 so that the pawl 112 and the ratchet 111 are engaged.

[0019] The connecting component includes a flange 13, which is welded to the output end of the motor 5 and the end of the take-up roller 6 near the motor 5. The flanges 13 of the motor 5 and the take-up roller 6 are respectively set and fixed by bolts. The clamping assembly 7 includes a lower clamping block 701 and an upper clamping plate 702 rotatably connected to the top of the lower clamping block 701 via a rotating shaft. The bottom of the lower clamping block 701 is welded to the horizontal part of the mounting block 4. The lower clamping block 701 and the upper clamping plate 702 are both provided with grooves 14 for accommodating the end of the take-up roller 6 on their respective sides. The upper clamping plate 702 and the lower clamping block 701 are fixedly installed by screws 15. The upper clamping plate 702 and the lower clamping block 701 are both provided with threaded holes for connecting with the screws 15.

[0020] When the printed fabric is wound up after processing, the axes of the two take-up rollers 6 are parallel to the axis of the guide roller 2. The guide roller 2 is driven to rotate by starting the reduction motor 5, and the fabric is first fed to the roller surface of the guide roller 2 and then wound around the roller surface of one of the take-up rollers 6 near the guide roller 2. At this time, the fabric is wound up in the take-up frame. Then, the take-up roller 6 is driven to rotate by starting the motor 5 near the guide roller 2. At this time, bolts are respectively installed on the flange 13 at the output end of the motor 5 and the end of the take-up roller 6, and the inner walls of the grooves 14 on the upper clamping plate 702 and the lower clamping block 701 abut against the outer peripheral wall of the end of the take-up roller 6, and the screws 15 are respectively connected to The threaded holes in the upper clamping plate 702 and the lower clamping block 701 can clamp and install the end of the take-up roller 6, improving the stability of the take-up roller 6 during rotation. This allows the output of the motor 5 to drive the take-up roller 6 to rotate, thus winding the fabric. After one of the take-up rollers 6 near the guide roller 2 has finished winding the fabric, the user holds the turntable 3 and rotates it clockwise. The rotation of the turntable 3 drives the rotating shaft 10 and the two take-up rollers 6 to rotate. At this time, the bottom end of the rotating shaft 10 rotates on the top surface of the mounting plate 9. The rotation of the rotating shaft 10 drives the ratchet 111 to rotate, and the ratchet 111, during its rotation, drives the pawl 112 to rotate, causing the pawl 112 to rotate. 12. First, rotate the pawl 112 away from the ratchet 111 until it contacts the leaf spring 12. At this point, the pawl 112 pushes and deforms the unattached end of the leaf spring 12, causing it to disengage from one of the ratchet 111 teeth. Then, the leaf spring 12 recovers its elasticity and pushes the pawl 112, causing it to rotate towards the ratchet 111 until it engages with the other ratchet 111 teeth. This allows the turntable 3 to remain stationary when not rotating, as the pawl 112 engages with the ratchet 111. The user then continues to rotate the turntable 3 clockwise, driving the two take-up rollers 6 to rotate. When the turntable 3 rotates, neither the motor 5 nor the mounting block 4 contacts the inner wall of the take-up frame until another unused take-up roller 6 approaches the guide roller 2 and their axes are relatively parallel. This allows the other unused take-up roller 6 to approach the guide roller 2 for taking up the next roll of fabric. When the other unused take-up roller 6 is taking up the fabric, the take-up roller 6 that has completed taking up the fabric can be removed from the mounting block 4 on the turntable 3 through the connector and replaced with a new take-up roller 6. This allows the other take-up roller 6 to be used to take up a new roll of fabric while one of the take-up rollers that has completed taking up the fabric is removed, thereby improving the take-up efficiency of the fabric.

[0021] When one of the take-up rollers 6 finishes winding the fabric and another unused take-up roller 6 is used to wind the fabric, first, the screw 15 on the take-up roller 6 that has finished winding is removed, so that the screw 15 is disengaged from the threaded holes of the upper clamping plate 702 and the lower clamping block 701 respectively. Then, the upper clamping plate 702 is rotated until the inner wall of the groove 14 in the upper clamping plate 702 is no longer in contact with the end of the take-up roller 6. Then, the bolts are removed so that they are disengaged from the flange 13 at the output end of the motor 5 and the end of the take-up roller 6 respectively. Then, the user lifts the take-up roller 6 that has finished winding the fabric upwards until the end of the take-up roller 6 is no longer in contact with the inner wall of the groove 14 in the lower clamping block 701, and the motor 5 output is released. The flange 13 at the exit end does not fit with the flange 13 at the end of the take-up roller 6, so that when the other take-up roller 6 is taking up the fabric, the take-up roller 6 that has finished taking up the fabric can be disassembled at the same time and replaced with a new take-up roller 6 for use. Moreover, by moving the telescopic end of the hydraulic rod 8 upward, the mounting plate 9, the turntable 3 and the two take-up rollers 6 can be moved upward respectively, and by moving the telescopic end of the hydraulic rod 8 downward, the mounting plate 9, the turntable 3 and the two take-up rollers 6 can be moved downward respectively, so as to adjust the working height of the take-up roller 6. Thus, the height position of the take-up roller 6 can be adjusted according to the actual use requirements, improving the winding efficiency and also improving the versatility of the winding device.
