Description

Technical Field

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

[0002] Fabric dyeing involves conveying the fabric to a dyeing box containing dye for dyeing. Usually, multiple guide rollers are installed inside the dyeing box to guide and transport the fabric. During the dyeing process, the guide rollers are used to guide the fabric and facilitate its delivery into the dyeing box for dyeing.

[0003] The existing guide rollers are in a relatively fixed position inside the dyeing box, which means that when the fabric is transported to the dyeing box by the guide rollers, the path length that the fabric travels in the dyeing box is the same, and the contact time between the fabric and the dye in the dyeing box is the same. It is not possible to adjust the path length that different fabrics travel in the dyeing box by adjusting the position of the guide rollers, so it cannot meet the processing requirements of different fabrics.

[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 fabric dyeing device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fabric dyeing device, including a dyeing box and multiple guide rollers, wherein the top of the dyeing box is open and a mounting frame is fixedly connected to the top of the dyeing box, and a horizontal adjustment mechanism for moving the guide rollers in the horizontal direction is provided on the mounting frame, wherein the number of horizontal adjustment mechanisms corresponds one-to-one with the number of guide rollers, and a vertically arranged hydraulic rod is fixedly connected to the horizontal adjustment mechanism, wherein the bottom of the hydraulic rod is a telescopic end, and a movable frame with an inverted U-shaped cross section is fixedly installed at the bottom of the hydraulic rod through a connecting assembly, and the guide rollers are rotatably connected inside the movable frame.

[0007] Preferably, the leveling mechanism includes a lead screw and a threaded block. The lead screw is horizontally positioned and rotatably connected to the mounting bracket. The lead screw passes through the threaded block, which is threadedly connected to the outer peripheral wall of the lead screw. The top of the hydraulic rod is fixedly connected to the bottom of the threaded block.

[0008] Preferably, the connecting assembly includes two flanges, and an installation rod is fixedly connected to the top of the movable frame. The two flanges are respectively fixedly connected to the bottom of the hydraulic rod and the top of the installation rod. The flanges on the hydraulic rod and the installation rod are correspondingly arranged, and the corresponding flanges are fixedly installed by bolts.

[0009] Preferably, a bevel gear one is fixedly connected to the outer peripheral wall of the end of the guide roller and is arranged coaxially. A motor is fixedly connected to the top of the moving frame. The output end of the motor passes through the top of the moving frame and a bevel gear two that meshes with the bevel gear one is fixedly connected to the output end of the motor.

[0010] Preferably, a snap-fit ​​frame is fixedly connected to the outer side wall of the movable frame, and a cleaning pad is provided on the snap-fit ​​frame. The cleaning pad is used to abut against the inner side wall of the dyeing box.

[0011] Preferably, the snap-fit ​​frame includes an upper abutment strip, a lower abutment strip, and two side plates.

The user can use the horizontal adjustment mechanism to move the hydraulic rod, movable frame, and guide roller horizontally, adjusting the horizontal distance between adjacent guide rollers. The hydraulic rod can also move the movable frame and guide roller vertically to adjust the height of the guide rollers, allowing adjustment of the height difference between adjacent guide rollers. This allows for adjustment of the horizontal distance or height difference between adjacent guide rollers by moving the guide rollers horizontally or vertically according to different fabrics.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Example:

[0019] A fabric dyeing apparatus, such as Figures 1 to 3As shown, the apparatus includes a dyeing box 1 and multiple guide rollers 2. The dyeing box 1 has an inlet and an outlet on both sides. The top of the dyeing box 1 is open, and a mounting frame 3 is welded to the top of the dyeing box 1. The mounting frame 3 corresponds vertically to the dyeing box 1. A horizontal adjustment mechanism 4 is mounted on the mounting frame 3 to move the guide rollers 2 horizontally. The number of horizontal adjustment mechanisms 4 corresponds one-to-one with the number of guide rollers 2. Vertically arranged hydraulic rods 5 are welded to the horizontal adjustment mechanisms 4. There are four horizontal adjustment mechanisms 4, four guide rollers 2, and four hydraulic rods 5. The bottom of the hydraulic rod 5 is a telescopic end, and a movable frame 7 with an inverted U-shaped cross-section is fixedly installed at the bottom of the hydraulic rod 5 through a connecting assembly. The guide roller 2 is rotatably connected inside the movable frame 7, and the guide roller 2 and the inner top wall of the movable frame 7 form a gap for the fabric to pass through. The horizontal adjustment mechanism 4 includes a lead screw 401 and a threaded block 402. The lead screw 401 is horizontally set and rotatably connected to the mounting frame 3. The lead screw 401 is rotatably connected to the mounting frame 3 through a servo motor. The output end of the servo motor passes through the side wall of the mounting frame 3 and is welded to one end of the lead screw 401. The number of servo motors and lead screws 401 corresponds to the number of four. Lead screws 401 pass through threaded blocks 402, which are threaded onto the outer peripheral wall of lead screws 401. The outer peripheral wall of lead screws 401 is machined with external threads, and the interior of threaded blocks 402 is machined with internal threads that mate with the outer peripheral wall of lead screws 401. The top of hydraulic rod 5 is welded to the bottom of threaded block 402. The connecting assembly includes two flanges 6. A mounting rod 8 is welded to the top of the moving frame 7. The mounting rod 8 is vertically positioned and corresponds to the hydraulic rod 5. The two flanges 6 are respectively welded... At the bottom of the hydraulic rod 5 and the top of the mounting rod 8, flanges 6 are correspondingly set on the hydraulic rod 5 and the mounting rod 8. The corresponding flanges 6 are fixedly installed by bolts. The end of the guide roller 2 is rotatably installed on the inner side wall of the moving frame 7. A bevel gear 9 is welded to the outer peripheral wall of the end of the guide roller 2. The bevel gear 9 is welded to one end of the guide roller 2. A motor 10 is installed on the top of the moving frame 7 by screws. The output end of the motor 10 passes through the top of the moving frame 7. A bevel gear 11 that meshes with the bevel gear 9 is welded to the output end of the motor 10.

[0020] A snap-fit ​​frame 12 is bonded to the outer wall of the movable frame 7. A cleaning pad 13 is installed on the snap-fit ​​frame 12. The cleaning pad 13 is used to abut against the inner wall of the dyeing box 1. The snap-fit ​​frame 12 includes an upper abutment strip 121, a lower abutment strip 122, and two side plates 123. The upper abutment strip 121, the lower abutment strip 122, and the side plates 123 are integrally formed. The upper abutment strip 121 and the lower abutment strip 122 are both located between the two side plates 123. The upper abutment strip 121 and the lower abutment strip 122 are arranged symmetrically from top to bottom. Both have L-shaped cross sections. The upper abutment strip 121 and the lower abutment strip 122 are both bonded to the outer side wall of the moving frame 7. The cleaning pad 13 has elastic recovery properties. The cleaning pad 13 is made of sponge and abuts against the upper abutment strip 121, the lower abutment strip 122 and the two side plates 123 respectively. The top of the cleaning pad 13 is used to abut against the vertical part of the upper abutment strip 121, and the bottom of the cleaning pad 13 is used to abut against the vertical part of the lower abutment strip 122.

[0021] The user starts motor 10 to rotate its output end. When the output end of motor 10 rotates, it drives bevel gear 11 to rotate. Because bevel gear 11 meshes with bevel gear 9, and bevel gear 9 is installed at one end of guide roller 2, the rotation of the output end of motor 10, through the meshing of bevel gear 9 and bevel gear 11, can drive guide roller 2 to rotate within moving frame 7. When guide roller 2 rotates, motor 10 does not contact the dye in dyeing box 1. Afterwards, the user can start the servo motor to drive lead screw 401 to rotate clockwise. When lead screw 401 rotates clockwise, it drives threaded block 402, hydraulic rod 5, moving frame 7, and guide roller 2 respectively. Moving horizontally towards the servo motor, the screw 401 rotates counterclockwise, driving the threaded block 402, hydraulic rod 5, moving frame 7, and guide roller 2 to move horizontally away from the servo motor. When the guide roller 2 moves horizontally, it is located inside the dyeing chamber 1, allowing adjustment of the horizontal distance between adjacent guide rollers 2. Increasing the horizontal distance increases the path length of the fabric within the dyeing chamber 1, thus increasing the contact time between the fabric and the dye. Conversely, decreasing the horizontal distance reduces the path length of the fabric within the dyeing chamber 1, thus shortening the contact time between the fabric and the dye. The contact time of the dye phase in the dyeing box 1 is controlled by moving the bottom of the hydraulic rod 5 upward, which in turn moves the moving frame 7 and the guide roller 2 upward, thereby increasing the working height of the guide roller 2. Conversely, moving the bottom of the hydraulic rod 5 downward, which in turn moves the moving frame 7 and the guide roller 2 downward, thereby decreasing the working height of the guide roller 2. When one guide roller 2 moves upward or downward and its adjacent guide roller 2 does not move or moves only a small distance, this can be used to increase the height difference between the two adjacent guide rollers 2. This increases the distance between the fabric and the guide roller 2 as it is guided from above or below to the adjacent guide roller 2. After passing through the feed inlet and then through multiple guide rollers... The guide roller 2 transports the fabric to the dyeing box 1 for dyeing. At this time, the fabric will pass through the gap between the guide roller 2 and the top wall of the moving frame 7. When the fabric is guided and transported by multiple guide rollers 2, it is transported and dyed in a wave-like shape in the dyeing box 1. Afterwards, the fabric is transported out of the dyeing box 1 through the discharge port. Thus, the guide rollers 2 can be moved horizontally or vertically to adjust the horizontal distance or height difference between adjacent guide rollers 2 according to different fabrics. This allows the path length of the fabric when it is guided and transported to the dyeing box 1 by multiple guide rollers 2 to be adjusted, thereby adjusting the contact time between the fabric and the dye in the dyeing box 1, which can meet the dyeing processing needs of different fabrics.

[0022] By removing the bolts to detach them from the flanges 6 on the hydraulic rod 5 and mounting rod 8 respectively, the movable frame 7 and guide roller 2 can be removed from the bottom of the hydraulic rod 5 and removed from the gap between the dyeing box 1 and the mounting frame 3 for cleaning or replacement of the guide roller 2.

[0023] When the fabric is guided and transported into the dyeing box 1 by the guide roller 2, the cleaning pad 13 is not installed in the snap-fit ​​frame 12. After the fabric is discharged through the outlet, the bottom of the hydraulic rod 5 is moved upward, which in turn moves the moving frame 7 and the guide roller 2 upward until the moving frame 7 is disengaged from the inside of the dyeing box 1. Then the cleaning pad 13 is snapped into the snap-fit ​​frame 12. Because the cleaning pad 13 has elastic recovery, the user can compress and deform it by squeezing the top and bottom of the cleaning pad 13, and then it will be in a compressed state. The cleaning pad 13 is placed inside the snap-fit ​​frame 12. Then, by releasing the cleaning pad 13, it gradually regains its elasticity until the top of the cleaning pad 13 is pressed by the vertical part of the upper abutment bar 121, causing the top of the cleaning pad 13 to deform and press firmly. Simultaneously, the bottom of the cleaning pad 13 is pressed firmly by the vertical part of the lower abutment bar 122. At this point, the two sides of the cleaning pad 13 are pressed against the two side walls, facilitating the installation of the cleaning pad 13 inside the snap-fit ​​frame 12. Then, by moving the bottom of the hydraulic rod 5 downwards, the frame is moved. 7. The guide roller 2 and cleaning pad 13 move until one side of the cleaning pad 13 is in contact with the inner wall of the dyeing frame. Then, the horizontal adjustment mechanism 4 drives the moving frame 7 and cleaning pad 13 to move horizontally, and the hydraulic rod 5 drives the moving frame 7 and cleaning pad 13 to move vertically. This is used to adjust the position of the cleaning pad 13 in the dyeing box 1 to facilitate cleaning of the inner wall of the dyeing box 1. When cleaning the inner wall of the dyeing box 1, the cleaning pad 13 is supported by the upper abutment strip 121, the lower abutment strip 122 and the two side plates 123. To prevent the cleaning pad 13 from falling off the moving frame 7, when the cleaning pad 13 needs to be replaced, the bottom of the hydraulic rod 5 is moved upward to drive the moving frame 7 and the cleaning pad 13 to move until the cleaning pad 13 is no longer in contact with the inner wall of the dyeing box 1. Then, the cleaning pad 13 is pulled along the axis of the guide roller 2 to remove it from the snap-fit ​​frame 12. At this time, the cleaning pad 13 is deformed and its top and bottom are no longer in contact with the upper abutment strip 121 and the lower abutment strip 122, respectively, making it easy to remove and replace the cleaning pad 13 from the snap-fit ​​frame 12.
