Description

Technical Field

[0001] The invention relates to the technical field of fabric dyeing, in particular to a dyeing mechanism used for cushion processing. Background Art

[0002] Cushions are indispensable fabric products in the bedroom. They are a product in which cotton is filled in a sealed fabric. The fabrics include coral fleece, cotton and linen blends, nylon, polyester and cotton, simulated silk satin, etc. They are comfortable to use and have irreplaceable decorative effects that other items cannot replace. Cushions are used to adjust the contact points between the human body and seats and beds to obtain a more comfortable angle to reduce fatigue. Therefore, they are used in various occasions and environments. In order to improve the comfort of cushions during use, elastic fabrics are used to make cushions. The outer fabric can be stretched when people squeeze the cotton core to better fit the contact points, making it more comfortable to use. However, in the production process of cushions, in order to meet the preferences of different users, the cushion fabrics will be dyed into different colors, so dyeing equipment is needed.

[0003] The prior art discloses an open-type dyeing device for stretch fabrics with a publication number of CN116988238A. By opening the upper lifting frame and the lower lifting frame in the printing and dyeing component for relative operation, the stretch fabric transmitted between the upper pressing roller and the lower pressing roller pair equipped with an annular pressure plate can be squeezed and deformed to fully open the length and width directions of the stretch fabric. The upper roller brush and the lower roller brush can be used to efficiently print and dye the stretch fabric, thereby improving the printing and dyeing efficiency and quality of the stretch fabric. The washing component cooperates with the annular roller body to allow the stretch fabric here to pass back and forth, and then the washing component is used to clean the stretch fabric step by step, thereby replacing the traditional flat-width washing equipment, improving the washing efficiency of the stretch fabric, and reducing the space occupied by the equipment assembly.

[0004] However, there are still some defects in actual use. Since the expansion component of the dyeing device can only expand the elastic fabric to the two sides for dyeing, it is impossible to fully expand the elastic fabric to the four sides for extrusion dyeing, and thus the elastic fibers woven in the longitudinal direction cannot be evenly contacted with the dye for dyeing. Multiple rounds of printing and dyeing are required to ensure that the elastic fabric is completely printed and dyed, which greatly reduces the production efficiency of the device.

DETAILED DESCRIPTION

[0030] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0031] like Figure 1-Figure 8A dyeing mechanism for cushion processing shown in the figure comprises an unwinding mechanism 1, a dyeing tank 2, a drying mechanism 3 and a winding mechanism 4 which are connected in sequence. A pressing mechanism 39 for cleaning up excess dye is provided on the inner side of the dyeing tank 2. The pressing mechanism 39 is mainly driven by a motor to drive a pressing roller to rotate, and another pressing roller is driven to rotate through two sets of gears to squeeze out excess dye passing through the fabric. Guide rollers 5 for guiding materials are rotatably connected to the top of both sides of the inner wall of the dyeing tank 2. A pair of pressing rollers 7 for pressing the fabric are rotatably connected to the bottom of the inner side of the dyeing tank 2. A support frame 6 is fixedly connected to the top of the dyeing tank 2 and located between the pressing rollers 7. A servo telescopic cylinder 8 is fixedly connected to the top of the support frame 6. A pair of L-shaped frames 9 are provided below the support frame 6. An adjusting mechanism for adjusting the spacing between the L-shaped frames 9 is provided on the support frame 6. The output end of the servo telescopic cylinder 8 is fixedly connected to a top plate 10 through the top of the support frame 6. An extrusion mechanism for pressing the corners and holding open the elastic fabric is provided below the top plate 10.

[0032] When dyeing the elastic fabric of the cushion, the traction rope of the elastic fabric on the unwinding mechanism 1 is pulled over the guide roller 5 on the dyeing tank 2, and then passes under the two pressing rollers 7 in turn, and then passes through the pressing mechanism 39, and then passes over the other guide roller 5, and finally passes through the drying mechanism 3 in turn and is wound on the winding mechanism 4, and the equipment can be driven to start dyeing the cushion fabric.

[0033] The extrusion mechanism includes side rollers 11 and a support plate 12. A bottom plate 13 is provided below the top plate 10. A pair of sliding rods 14 are fixedly connected to the top of the bottom plate 13 and pass through the top of the top plate 10. An upper spring 40 is fixedly connected between the bottom of the top plate 10 and the top of the bottom plate 13. A rectangular rod 15 is fixedly connected to the center of the bottom of the top plate 10 and passes through the bottom of the bottom plate 13. The support plate 12 is fixedly connected to the bottom end of the rectangular rod 15. A pair of round holes 16 are penetrated through the side wall of the bottom plate 13. A clamping plate 18 is provided on the inner side of the L-shaped frame 9, and a round rod 17 is fixedly connected to the side close to the clamping plate 18 and is slidably connected to the inner side of the round hole 16. Through the arrangement of the round hole 16 and the round rod 17, when the adjustment mechanism drives the L-shaped frame 9 to slide, the round rod 17 can be driven to slide in the round hole 16. Not only will it not hinder the normal operation of the adjustment mechanism, but it also ensures the connection between the clamping plate 18 and the bottom plate 13. A pair of fixing plates 19 are fixedly connected to the bottom of the side close to the L-shaped frame 9. The side rollers 11 are fixedly connected between the fixing plates 19. A clamping mechanism for clamping the two sides of the elastic fabric is provided next to the bottom plate 13. The bottom of the opening plate 12 is set to a smooth arc surface to avoid damage to the elastic fabric at the corners and improve the production quality of the device. The clamping plate 18 is set to an arc shape that fits the outer wall of the side roller 11, which can improve the clamping effect on both sides of the elastic fabric and ensure the stable clamping of the device. The top of the slide rod 14 is fixedly connected to the limit plate 31. Through the setting of the limit plate 31, the limit plate 31 can be pushed when the top plate 10 slides upward, driving the slide rod 14 and the bottom plate 13 to slide upward;

[0034] The clamping mechanism includes a clamping roller 21, a fixing frame 20 is provided inside the dyeing tank 2 and above the pressing roller 7, an inwardly sunken slide groove 22 is provided on the front and rear sides of the inner wall of the dyeing tank 2 and at positions corresponding to the fixing frame 20, the fixing frame 20 is slidably connected to the inside of the slide groove 22, the clamping roller 21 is fixedly connected to the inside of the fixing frame 20, a fixing roller 42 is provided on the side away from the clamping roller 21, a lower inclined block 23 is fixedly connected to the middle position of the top of the fixing frame 20, the two lower inclined blocks 23 are symmetrically arranged, a connecting rod 24 is fixedly connected to the side wall of the bottom plate 13, an upper inclined block 25 that fits the inclined surface of the lower inclined block 23 is fixedly connected to the side away from the connecting rod 24, and a lower spring 26 for pushing the clamping roller 21 to reset is fixedly connected between the inner side of the slide groove 22 and the side wall of the fixing frame 20;

[0035] During the dyeing process of the cushion elastic fabric, the servo telescopic cylinder 8 can be controlled by the timing controller to start at a fixed time, thereby pushing the top plate 10 to move upward. At this time, the bottom plate 13 is pushed upward at the same time by the elastic force of the upper spring 40, and the clamping plate 18 is driven to slide downward by the round rod 17. As the servo telescopic cylinder 8 continues to drive, the clamping plate 18 is driven to squeeze the front and rear sides of the elastic fabric on the side roller 11. At the same time, when the bottom plate 13 moves downward, the upper inclined block 25 is driven to move downward at the same time through the connecting rod 24. Then, when the upper inclined block 25 moves and fits with the inclined surface of the lower inclined block 23, the lower inclined block 23 is squeezed, so that as the upper inclined block 25 gradually moves downward, the lower inclined block 23 and the fixed frame 20 are pushed to move to both sides, and the lower spring 26 in the slide groove 22 is compressed, so that the clamping roller 21 moves toward the side close to the fixed roller 42, and the left and right sides of the elastic fabric are clamped between the clamping roller 21 and the fixed roller 42, so as to achieve simultaneous clamping of the four sides of the elastic fabric in the dyeing tank 2;

[0036] Finally, the servo telescopic cylinder 8 continues to drive. At this time, the bottom plate 13 is restricted by the clamping plate 18 on the side roller 11, which prevents the bottom plate 13 from continuing to slide downward. As a result, when the top plate 10 continues to slide downward, it will compress the upper spring 40, thereby driving the rectangular rod 15 and the stretching plate 12 to move downward to push the center of the elastic fabric, and then stretch the four sides of the elastic fabric toward the middle direction at the same time, ensuring that the longitudinal and transverse woven elastic fibers can be stretched to evenly contact the dye in the dyeing tank 2, thereby improving the dyeing efficiency of the device. Finally, the servo telescopic cylinder 8 can be controlled to be retracted.

[0037] In order to further improve the dyeing effect of the device, a dyeing sponge 27 for pressure dyeing the elastic fabric at the clamping position is fixedly connected to the side close to the clamping plate 18 and the side roller 11. Through the arrangement of the dyeing sponge 27, when the clamping plate 18 and the side roller 11 clamp both sides of the elastic fabric, the two sides of the elastic fabric can be squeezed, so that the dye adsorbed on the dyeing sponge 27 is squeezed into the elastic fabric, thereby increasing the speed at which the elastic fabric absorbs the dye, and further improving the dyeing efficiency of the elastic fabric.

[0038] In order to control the stretching force, a waterproof pressure sensor 28 is provided at the bottom of the dyeing pool 2 and at a position corresponding to the stretching plate 12, and the waterproof pressure sensor 28 is electrically connected to the servo telescopic cylinder 8 through a controller. Before use, the pressure sensing value of the waterproof pressure sensor 28 can be set, so that when the extrusion mechanism drives the elastic fabric to stretch, the stretching plate 12 will touch the waterproof pressure sensor 28 at the bottom. When the stretching plate 12 gradually moves downward and applies pressure to the waterproof pressure sensor 28 to reach a specified value, the waterproof pressure sensor 28 will transmit a signal to the controller, and then the controller controls the servo telescopic cylinder 8 to retract the stretching plate 12, so that different forces can be stretched according to fabrics with different elastic forces, thereby further improving the dyeing effect of the device.

[0039] In order to further improve the degree of automation of the device, a positioning plate 29 is fixedly connected to the bottom of the support frame 6 and is located next to the top plate 10. A travel switch 30 is fixedly connected to the positioning plate 29, and the touch end of the travel switch 30 is in contact with the top of the top plate 10. The travel switch 30 is electrically connected to the winding motor of the winding mechanism 4 through the controller. When the servo telescopic cylinder 8 drives the top plate 10 to move downward, it will drive the top plate 10 to move out of the contact position with the touch end of the travel switch 30. Then the travel switch 30 transmits a signal to the controller, and the controller controls the motor on the winding mechanism 4 that provides tension for the elastic fabric to be turned off, so that the fabric can be automatically controlled to stop conveying before the elastic fabric is stretched, thereby ensuring the stable operation of the subsequent extrusion mechanism, and the travel switch 30 will be touched when the top plate 10 is reset, so that the dyed fabric can be conveyed away, and the automatic stretching and dyeing of the fabric can be achieved repeatedly in this way.

[0040] In order to enable the extrusion mechanism to stretch and dye elastic fabrics of different widths, the adjustment mechanism includes a bidirectional screw rod 32 and a servo motor 33. An inward adjustment groove 34 is provided on the top of the support frame 6. The bidirectional screw rod 32 is rotatably connected to the inner side of the adjustment groove 34. The servo motor 33 is fixedly connected to the side wall of the support frame 6. The output end of the servo motor 33 passes through the adjustment groove 34 and is fixedly connected to the side wall of the bidirectional screw rod 32. A pair of sliding blocks 35 are threadedly connected to the outer wall of the bidirectional screw rod 32. Figure 6 It can be seen that the sliding block 35 is adapted to the adjustment slot 34, and can play a guiding role when the two-way screw rod 32 rotates to drive the sliding block 35 to move, so as to prevent the sliding block 35 from rotating with the two-way screw rod 32. The bottom of the sliding block 35 is fixedly connected to the top of the L-shaped frame 9, and a pair of guide rods 36 are fixedly connected to the top of the clamping plate 18 and are arranged through the top of the L-shaped frame 9. Through the arrangement of the guide rods 36, when the servo telescopic cylinder 8 drives the clamping plate 18 to move up and down, the guide rods 36 can be driven to slide up and down on the L-shaped frame 9, thereby ensuring the connection between the clamping plate 18 and the L-shaped frame 9, and will not hinder the up and down movement of the clamping plate 18, so as to avoid affecting the subsequent adjustment of the spacing between the clamping plates 18;

[0041] When dyeing elastic fabrics of different widths and adjusting the spacing between the L-shaped frames 9 is required, the servo motor 33 is controlled to start and drive the bidirectional screw rod 32 to rotate, thereby driving the two threaded sliding blocks 35 to move toward or away from each other, and at the same time driving the L-shaped frame 9 to move, thereby adjusting the side clamping position of the elastic fabric, and then elastic fabrics of different widths can be stretched and dyed, further improving the scope of application of the device.

[0042] In order to accurately adjust the spacing between the L-shaped frames 9, a pointer 37 is fixedly connected to the top of one of the sliding blocks 35, and an inward-recessed length scale groove 38 is opened on the top of the support frame 6 and next to the pointer 37. When the sliding block 35 slides to adjust the spacing between the L-shaped frames 9, the pointer 37 will be driven to move, and then by observing the position of the pointer 37 on the length scale groove 38, the servo motor 33 can be controlled to accurately adjust the position of the L-shaped frame 9 according to the size of the elastic fabric.

[0043] The basic principles, main features and advantages of the present invention are shown and described above.
