Description

Technical Field

[0001] The present application relates to the technical field of fur dyeing, and in particular to a dyeing device and a process for dyeing imitation animal fur clothing fabrics. Background Art

[0002] In the field of modern textile and leather manufacturing, in order to meet consumers' demand for product diversification and beauty, the application of imitation animal fur clothing fabrics is becoming more and more widespread. Animal fur is deeply loved by people for its unique texture and appearance. However, due to factors such as animal protection and cost, imitation animal fur clothing fabrics have gradually become the mainstream choice in the market. Imitation animal fur fabrics usually have fine and dense fur on one side. In order to more realistically imitate the natural effect of animal fur and increase the layering of product color, it is often necessary to dye the tip of the fur (i.e. the tip of the fur) so that the tip and end of the fur present different colors.

[0003] At present, when printing and dyeing the hair tips of imitation animal fur fabrics, most of them rely on manual operation. The fur fabric is spread flat on the table with the fur side facing up, and the worker uses a brush to contact the hair tips and brushes repeatedly to complete the hair tip dyeing.

[0004] However, the manual printing and dyeing method has obvious defects. Since it relies entirely on manual strength and experience, it is difficult to ensure the consistency of the contact between the brush and the fluff. This leads to uneven dyeing degrees on different hair tips and extremely poor printing and dyeing uniformity, which affects the quality and aesthetics of the imitation animal fur fabric. Summary of the invention

[0005] In order to improve the uniformity of hair tip printing and dyeing of imitation animal fur and ensure the quality and aesthetics of the imitation animal fur, the present application provides a dyeing device and a process for imitation animal fur clothing fabrics.

[0006] In the first aspect, the present application provides a dyeing device for imitation animal fur clothing fabrics, which adopts the following technical scheme: it includes a base, a frame is fixedly arranged on the base, a winding wheel and a tensioning wheel are rotatably arranged on the top of the frame, a traction rope is wound around the winding wheel, and the end of the traction rope is connected to one end of the fur fabric through a clip, and an intermittent rotating component is arranged on the frame, and the intermittent rotating component is used to drive the winding wheel to intermittently rotate in the direction of winding the traction rope; a tensioning rope is wound around the tensioning wheel, and the end of the traction rope is connected through a clip. A clip is connected to the other end of the fur fabric; a dye tray for storing dye is fixedly arranged on the base, a slide rail is fixedly arranged on the frame, the slide rail is located directly above the dye tray, a slider is slidably arranged on the slide rail, a brush roller is rotatably arranged on the slider, the top side of the brush roller contacts the tip of the fur fabric, and the bottom side of the brush roller contacts the dye in the dye tray, a rotating part is arranged on the slider, the rotating part is used to drive the brush roller to rotate, and a reciprocating sliding assembly is also arranged on the frame, the reciprocating sliding assembly is used to drive the slider to slide back and forth.

[0007] By adopting the above technical scheme, when dyeing the hair tips of the imitation animal fur fabric, the hair tips of the fabric to be dyed are connected to the traction rope and the tension rope respectively through clips, and the brush roller contacts the dye in the dye tray driven by the rotating part to pick up the dye; the reciprocating sliding component drives the slider to slide back and forth on the slide rail, and the brush roller brushes and dyes the hair tips; the intermittent rotation of the winding wheel is controlled by the intermittent rotation component, and the winding wheel intermittently pulls the fur fabric through the winding rope, changing the contact position of the brush roller and the fur fabric, so as to dye the hair tips at different positions of the fur fabric, thereby improving the uniformity of printing and dyeing of the hair tips of the imitation animal fur and ensuring the quality and aesthetics of the imitation animal fur.

[0008] Optionally, a pressure rod is provided on the top of the frame in the vertical direction, a mounting frame is fixedly provided at the bottom of the pressure rod, a group of pressure rollers are rotatably provided at the bottom of the mounting frame, the circumferential surface of the pressure rollers is in contact with the fur fabric and presses down the fur fabric, and the brush roller is in contact with the part of the fur fabric pressed down by the pressure rollers.

[0009] By adopting the above technical solution, the mounting frame and the pressure roller at the bottom of the pressure rod can press the fur fabric downward, increasing the stability of the fur fabric and making the contact between the brush roller and the fur fabric more stable, thereby further improving the uniformity and effect of dyeing and reducing defects in the dyeing process.

[0010] Optionally, a cylinder is fixedly arranged on the top of the frame, and the top end of the pressure rod is fixedly connected to the output end of the cylinder.

[0011] By adopting the above technical solution, the cylinder can flexibly control the lifting and lowering of the pressure rod, thereby adjusting the degree of downward pressure of the pressure roller on the fur fabric according to the specific requirements of the dyeing degree of the fur tip of the fur fabric, thereby adjusting the contact degree between the fluff and the brush roller, thereby improving the versatility and applicability of the equipment.

[0012] Optionally, the intermittent rotation component includes a groove wheel, a dial, a first motor, and a connecting piece, wherein the first motor is fixed on the frame, the dial is coaxially fixed with the driving shaft of the first motor, the groove wheel is rotationally connected to the rotating shaft of the winding wheel, the dial is used to drive the groove wheel to rotate intermittently, and the connecting piece is used to fix the groove wheel and the winding wheel in the circumferential direction.

[0013] By adopting the above technical solution, when it is necessary to drive the winding wheel to rotate intermittently, the first motor is started, and the driving shaft of the first motor drives the dial to rotate coaxially, and the convex pins on the dial contact the radial grooves on the groove wheel in turn. When the convex pins enter the radial grooves, the groove wheel is pushed to rotate a certain angle. During the time period when the convex pins of the dial do not contact the radial grooves of the groove wheel, the groove wheel is in a resting state, and because the connecting piece fixes the groove wheel and the winding wheel in the circumferential direction, the rotation of the groove wheel will drive the winding wheel to rotate synchronously; in this way, the groove wheel is continuously turned by the dial, and the groove wheel rotates intermittently, thereby realizing the intermittent rotation of the winding wheel and achieving the effect of intermittently winding the traction rope.

[0014] Optionally, the connecting member includes a first chuck and a second chuck, the first chuck is coaxially fixed with the winding wheel, the second chuck is threadedly matched with the rotating shaft of the winding wheel, and the first chuck and the second chuck have a common clamping groove.

[0015] By adopting the above technical solution, when it is necessary to fix the groove wheel and the winding wheel in the circumferential direction, tighten the second chuck so that it can clamp the groove wheel together with the first chuck to ensure that the groove wheel and the winding wheel are fixed in the circumferential direction, thereby realizing synchronous rotation of the two; when it is necessary to release the groove wheel and the winding wheel from fixation in the circumferential direction, loosen the second chuck.

[0016] Optionally, the reciprocating sliding assembly includes a connecting rod, a crank, a driving sprocket, a driven sprocket, and a transmission chain. The crank is rotatably arranged on a frame, one end of the connecting rod is hinged to the crank at a position offset from the axis, the other end of the connecting rod is hinged to the slider, the driving sprocket is coaxially fixed to the driving shaft of the first motor, the driven sprocket is coaxially fixed to the crank, one end of the transmission chain is meshed with the driving sprocket, and the other end of the transmission chain is meshed with the driven sprocket.

[0017] By adopting the above technical solution, when the first motor is started, the driving shaft of the first motor drives the active sprocket to rotate, and drives the driven sprocket to rotate through the transmission chain, thereby rotating the crankshaft. When the crankshaft rotates, its deviation from the axis drives the connecting rod to move, and the connecting rod pushes and pulls the slider to perform reciprocating sliding motion on the slide rail. In this way, only one motor is used to simultaneously drive the intermittent rotation of the winding wheel and the reciprocating sliding of the slider, thereby saving power source and simplifying the equipment structure.

[0018] Optionally, the center line of the motion trajectory of the slider passes through the rotation center of the curved plate, and the number of sprocket teeth of the driving sprocket is an integer multiple of the number of sprocket teeth of the driven sprocket.

[0019] By adopting the above technical solution, since the center line of the motion trajectory of the slider passes through the rotation center of the curved disk, the reciprocating sliding speed of the slider is consistent, which can ensure that the reciprocating sliding motion of the slider is more stable and smooth, and the number of sprocket teeth of the active sprocket is an integer multiple of the number of sprocket teeth of the driven sprocket. Therefore, every time the groove wheel rotates once, the slider reciprocates for an integer number of complete strokes, further improving the uniformity and quality of dyeing.

[0020] Optionally, a spring is provided at the rotational connection between the frame and the tensioning wheel, and the spring is used to undergo elastic deformation when the tensioning wheel releases the tensioning rope.

[0021] By adopting the above technical solution, when the traction rope pulls the fur fabric to move, the tensioning wheel releases the tensioning rope, the mainspring undergoes elastic deformation to store force, and ensures that the fur fabric is in a taut state, avoiding relaxation or wrinkles during the dyeing process as much as possible, which is conducive to the brush roller dyeing the hair tip more evenly, improving the dyeing effect and product quality; when the tensioning wheel needs to retighten the tensioning rope, the mainspring releases elastic potential energy to provide auxiliary power for the tensioning wheel, so that the tensioning rope can be quickly and effectively recovered.

[0022] Optionally, the rotating member includes a stepping motor, the stepping motor is fixedly disposed on the slider, and the driving shaft of the stepping motor is coaxially fixed with the brush roller.

[0023] By adopting the above technical solution, since the stepper motor has the characteristics of accurately controlling the rotation angle and speed, it is fixed on the slider and coaxially fixed with the brush roller, so that the rotation of the brush roller can be accurately controlled. During the dyeing process, the rotation speed and rotation angle of the brush roller can be flexibly adjusted according to specific dyeing needs, so that the brush roller can fully contact and absorb the dye in the dye tray, and at the same time, the contact with the hair tips of the fur fabric is more uniform and effective, thereby significantly improving the uniformity and quality of dyeing, and ensuring that the dyeing effect of the imitation animal fur fabric is better.

[0024] In the second aspect, the present application provides a dyeing process for imitation animal fur clothing fabrics using the following technical solutions: S1. Twist the second chuck to release the clamping of the first chuck and the second chuck on the groove wheel, so that the winding wheel can rotate freely; S2. Use the clip at the end of the traction rope to clamp one end of the fur fabric, and use the clip at the end of the tension rope to clamp the other end of the fur fabric, and ensure that the fur side of the fur fabric faces downward. The spring automatically restores its deformation to drive the tension wheel to reel in the tension rope, and the end of the fur fabric connected to the traction rope is located directly above the brush roller; S3, start the extended output end of the cylinder, move the pressure rod downward, the circumference of the pressure roller abuts against the fur fabric and presses the fur fabric downward, the brush roller contacts the hair tips of the fur fabric pressed by the pressure roller, and adjust the extension of the cylinder output end according to the required dyeing degree of the hair tips, twist the second chuck, so that the first chuck and the second chuck re-clamp the groove wheel; S4. Blow air on the fur fabric to make it fluffy, and the fur tends to droop under the action of gravity; S5, starting the stepper motor, so that the brush roller is stained with the dye in the dye tray, and the brush roller rotates at least one circle; S6, start the first motor, the dial and the curved disc rotate simultaneously, the curved disc drives the brush roller on the slider to slide back and forth continuously, the brush roller paints and dyes the hair tip, and during the sliding process, the stepper motor drives the brush roller to rotate an angle intermittently to replenish the dye at the contact position between the brush roller and the hair tip, the dial drives the groove wheel to rotate intermittently, the winding wheel intermittently pulls the fur fabric through the winding rope, and changes the contact position between the brush roller and the fur fabric; S6. Blow hot air on the dyed fur. After the dye is preliminarily dried on the fur tips, remove the fur from the traction rope and the tension rope and put it into a drying device for further drying.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting the dyeing disc, winding wheel, traction rope, tension wheel, tension rope, spring, slide rail, slider, brush roller, rotating part, intermittent rotating component, and reciprocating sliding component, the automation of the tip dyeing of the imitation animal fur fabric is realized, the uniformity of the tip printing and dyeing of the imitation animal fur is improved, and the quality and aesthetics of the imitation animal fur are guaranteed; 2.

A mounting frame 242 is fixedly disposed at the bottom of the pressure rod 241, and a group of pressure rollers 243 are rotatably disposed at the bottom of the mounting frame 242. The group of rollers are flush with each other in height, and the circumference of the pressure rollers 243 is against the non-pile surface of the fur fabric and presses down the fur fabric. The traction rope 211, the tension rope 221, and a group of rollers work together to tighten the fur fabric.

[0030] Reference Figure 1 A dye tray 11 for storing dye is fixedly arranged on the base 1, and a slide rail 23 is fixedly arranged on the frame 2 in the horizontal direction. The slide rail 23 is located directly above the dye tray 11, and a slider 231 is slidably arranged on the slide rail 23. A brush roller 232 is rotatably arranged on the slider 231, and there are bristles on the circumference of the brush roller 232. The top side of the brush roller 232 contacts the hair tips of the fur fabric pressed down by the pressed roller 243. And the sliding stroke of the brush roller 232 completely covers the length of the fur fabric pressed down by the pressed roller 243.

[0031] Reference Figure 1 The bottom side of the brush roller 232 contacts the dye in the dye tray 11, and a rotating member 233 is provided on the slider 231, and the rotating member 233 is used to drive the brush roller 232 to rotate. The rotating member 233 specifically includes a stepping motor, and the stepping motor is fixedly provided on the slider 231, and the driving shaft of the stepping motor is coaxially fixed with the brush roller 232. A reciprocating sliding assembly 4 is also provided on the frame 2, and the reciprocating sliding assembly 4 is used to drive the slider 231 to slide back and forth.

[0032] Reference Figure 1 When dyeing the hair tips of the imitation animal fur fabric, the hair tips to be dyed are connected to the traction rope 211 and the tension rope 221 with clips. The cylinder 24 is started to drive the pressure rod 241 to move downward, the pressure roller 243 presses the fur fabric downward, and the brush roller 232 contacts the hair tips of the pressed part. The output end of the cylinder 24 can be adjusted to extend outward according to the required dyeing degree of the hair tips, and the contact degree of the fluff and the brush roller 232 can be adjusted. The reciprocating sliding component 4 allows the slider 231 to reciprocate on the slide rail 23, and the brush roller 232 brushes and dyes the hair tips of the pressed part. The intermittent rotation component 3 controls the intermittent rotation of the winding wheel 21, and the winding wheel 21 intermittently pulls the fur fabric by the winding rope, changing the contact position of the brush roller 232 with the fabric, thereby dyeing the hair tips at different positions, improving the printing and dyeing uniformity, and ensuring the quality and aesthetics.

[0033] In order to facilitate the intermittent rotation of the winding wheel 21, refer to Figure 2 and Figure 3The intermittent rotation assembly 3 includes a groove wheel 31, a dial 32, a first motor 33, and a connecting member 34. The first motor 33 is fixedly arranged on the frame 2, the dial 32 is coaxially fixed with the driving shaft of the first motor 33, the groove wheel 31 is rotationally connected with the rotating shaft of the winding wheel 21, and the dial 32 is used to move the groove wheel 31 to make intermittent rotation. In this embodiment, only one convex pin is provided on the dial 32 for moving the convex pin groove wheel 31, and four radial grooves for inserting the convex pin are provided on the groove wheel 31. The connecting member 34 is used to fix the groove wheel 31 and the winding wheel 21 in the circumferential direction. The driving shaft of the first motor 33 drives the dial 32 to rotate coaxially, and a convex pin on the dial 32 contacts the radial groove on the groove wheel 31 in turn. When the convex pin enters the radial groove, the groove wheel 31 is pushed to rotate 90 degrees. During the period when the convex pin of the dial 32 does not contact the radial groove of the groove wheel 31, the groove wheel 31 is in a rest state, and because the connecting member 34 fixes the groove wheel 31 and the winding wheel 21 in the circumferential direction, the rotation of the groove wheel 31 drives the winding wheel 21 to rotate synchronously.

[0034] Reference Figure 2 and Figure 3 , wherein the connecting member 34 specifically includes a first chuck 341 and a second chuck 342. The first chuck 341 is coaxially fixed with the winding wheel 21, and the second chuck 342 is threadedly matched with the rotating shaft of the winding wheel 21, and the first chuck 341 and the second chuck 342 clamp the groove together. Tighten the second chuck 342, and the second chuck 342 and the first chuck 341 clamp the groove wheel 31 together, and the groove wheel 31 and the winding wheel 21 are fixed in the circumferential direction. Loosen the second chuck 342, and the groove wheel 31 no longer constrains the winding wheel 21 in the circumferential direction, so as to quickly release the traction rope 211.

[0035] In order to realize the reciprocating sliding of the slider 231, refer to Figure 1 and Figure 2 The reciprocating sliding assembly 4 includes a connecting rod 41, a crank 42, a driving sprocket 43, a driven sprocket 44, and a transmission chain 45. The crank 42 is rotatably arranged on the frame 2. The center line of the motion trajectory of the slider 231 passes through the rotation center of the crank 42. One end of the connecting rod 41 is hinged to the part of the crank 42 that deviates from the axis, and the other end of the connecting rod 41 is hinged to the slider 231. The driving sprocket 43 is coaxially fixed with the driving shaft of the first motor 33, and the driven sprocket 44 is coaxially fixed with the crank 42. One end of the transmission chain 45 is meshed with the driving sprocket 43, and the other end of the transmission chain 45 is meshed with the driven sprocket 44. The number of sprocket teeth of the driving sprocket 43 is an integer multiple of the number of sprocket teeth of the driven sprocket 44, and twice is used in this embodiment. When the first motor 33 rotates, the driving shaft of the first motor 33 drives the driving sprocket 43 to rotate, and drives the driven sprocket 44 to rotate through the transmission chain 45, thereby rotating the crank 42. The active motor rotates one circle, and the crank plate 42 rotates two circles. The crank plate 42 deviates from the axis and drives the connecting rod 41 to move. The connecting rod 41 pushes and pulls the slider 231 on the slide rail 23 to perform two reciprocating sliding movements.

[0036] The implementation principle of the embodiment of the present application is as follows: when dyeing the tips of the imitation animal fur fabric, first connect the fabric to be dyed to the traction rope 211 and the tension rope 221 respectively through the clips, and ensure that the side of the fur fabric with the fluff is facing downward, and the fluff tends to sag under the action of gravity. Then start the cylinder 24, move the pressure rod 241 downward, and the pressure roller 243 presses down the fur fabric, and adjust the extension of the output end of the cylinder 24 according to the specific dyeing requirements, so as to control the contact degree between the fluff and the brush roller 232. Next, start the first motor 33, the first motor 33 drives the dial 32 to rotate, and the convex pin of the dial 32 drives the groove wheel 31 to rotate intermittently. Since the groove wheel 31 and the winding wheel 21 are fixed by the connecting member 34, the winding wheel 21 intermittently reels the traction rope 211, changing the contact position between the fur fabric and the brush roller 232. At the same time, the first motor 33 drives the curved disc 42 to rotate through the driving sprocket 43, the transmission chain 45 and the driven sprocket 44, and the curved disc 42 drives the connecting rod 41 to make the slider 231 slide back and forth on the slide rail 23. Every time the reel 21 pulls the fur fabric once through the traction rope 211, the brush roller 232 on the slider 231 performs two reciprocating brushing actions on the hair tips of the fur fabric. In this process, the brush roller 232 rotates an angle intermittently under the drive of the stepper motor to replenish the dye at the contact position between the brush roller 232 and the hair tips. In this way, the uniformity of the hair tips of the imitation animal fur is improved, and the quality and aesthetics of the imitation animal fur are guaranteed.
