Description

Technical Field

[0001] This utility model relates to the field of fabric preparation technology, specifically to an environmentally friendly uniform printing and dyeing device for the preparation of bio-based fabrics. Background Technology

[0002] Bio-based fabrics refer to textile fabrics made from renewable biomass resources through a series of processing techniques. In the processing of bio-based fabrics, dyeing is required to meet the requirements of different colors. However, the current dyeing process is time-consuming and prone to uneven dyeing.

[0003] The utility model patent with authorization announcement number CN213538388U discloses an environmentally friendly dyeing and printing system for wool fabrics, including a dyeing and printing system body. The dyeing and printing system body includes a base, on which a dyeing and printing box and a washing box are installed. A drying box is installed between the dyeing and printing box and the washing box. Upper roller 1, upper roller 2, lower roller 1, and lower roller 2 are installed inside the dyeing and printing box and the washing box, respectively. Upper roller 1 and lower roller 1 cooperate with each other, and upper roller 2 and lower roller 2 cooperate with each other. A load-bearing cylinder is installed on the top of the dyeing and printing box and the washing box. A support rod is welded to the inner wall of the dyeing and printing box and a limit cylinder is installed on the support rod.

[0004] As shown in the above-mentioned utility model, existing printing and dyeing systems generally use rollers to squeeze and dye the fabric. During squeeze dyeing, the fabric is fully dyed by squeezing, avoiding uneven dyeing. This squeeze dyeing method improves the dyeing efficiency of the fabric to a certain extent. However, the fabric needs to stay in the dyeing box for a certain period of time. That is, the fabric's transmission speed during dyeing needs to be reduced to a rate at which the fabric can be fully dyed in the dyeing box, which reduces the dyeing efficiency of the fabric. Moreover, the fabric itself does not absorb much dye liquor during squeeze dyeing, but after squeezing, the fabric will still absorb some dye liquor in the dyeing box. This dye liquor is transported outside with the fabric without treatment, which can easily cause dye liquor to pollute the surrounding equipment or environment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an environmentally friendly uniform printing and dyeing device for the preparation of bio-based fabrics, thus solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly uniform dyeing and printing device for preparing bio-based fabrics, comprising:

[0007] The dyeing box has two symmetrically distributed dyeing rollers inside for transferring fabric within the box. Guide rollers are provided on both sides of the opening of the dyeing box for guiding the fabric in and out of the box.

[0008] A pressing component is fixed on both sides of the top of one end of the printing and dyeing box opening. A pressure roller is connected between the two pressing components. The pressure roller is located above one of the guide rollers. The pressure roller and the guide roller work together to squeeze the printed and dyed fabric to squeeze out excess dye from the fabric.

[0009] The movable component is located at the bottom of the inner cavity of the dyeing box. The movable component is driven by a drive mechanism located on the outside of the dyeing box to move and reciprocate to beat the fabric between the two guide rollers, thereby improving the dyeing efficiency of the fabric.

[0010] A connector, located inside the movable part, is used to connect the drive mechanism and the striking mechanism of the movable part, and to ensure the sealing of the drive mechanism.

[0011] Preferably, the clamping component includes a protruding plate fixed to one end of the top of the opening of the printing and dyeing box. A dovetail groove is formed in the middle of one side of the protruding plate. A movable plate is attached to one side of the protruding plate. A dovetail slider is fixed to one side of the movable plate. The dovetail slider is located in the dovetail groove and is used to drive the movable plate to move vertically up and down. The top of the dovetail slider is connected to the inner top wall of the dovetail groove by a spring. The middle of the other side of the movable plate is movably connected to the pressure roller by a pin.

[0012] Preferably, the movable component includes a motor disposed in the middle of the lower surface of the dyeing box, the motor being the drive mechanism, the output shaft of the motor being fixed with a reciprocating lead screw, one end of the reciprocating lead screw penetrating the inner bottom wall of the dyeing box and connected to the dyeing box through a sealed bearing.

[0013] Preferably, one end of the reciprocating screw is connected to a connector, and the top end of the connector is connected to a mounting frame. Both ends of the mounting frame are attached to the inner wall of the printing and dyeing box through extension plates. The upper surface of the mounting frame is fixed with a plurality of elastic columns arranged in a linear array, and the elastic columns correspond to the fabric between the two guide rollers.

[0014] Preferably, the connector includes two symmetrically arranged arc-shaped plates fixed in the middle of the lower surface of the mounting bracket. A connecting sleeve is fixed at the bottom end of the arc-shaped plate. The connecting sleeve is connected through the reciprocating lead screw, and the inner wall of the connecting sleeve is adapted to the helical groove of the reciprocating lead screw through a protrusion.

[0015] Preferably, the two arc-shaped plates are connected by a sealing sheet, and the bottom end of the connecting sleeve is connected to the inner bottom wall of the dyeing box by an elastic sealing sleeve, which is used to seal the end of the reciprocating screw located inside the dyeing box.

[0016] Beneficial effects

[0017] This invention provides an environmentally friendly uniform dyeing and printing device for the preparation of bio-based fabrics. Compared with the prior art, it has the following advantages:

[0018] 1. This environmentally friendly uniform dyeing and printing equipment for bio-based fabrics uses a movable part at the bottom of the dyeing and printing box. The motor drives the reciprocating screw to rotate, causing the connecting sleeve and mounting frame to move up and down. The elastic column on the mounting frame continuously impacts the fabric between the dyeing and printing rollers, increasing the contact area between the fabric and the dye liquor. The fabric can be fully dyed without reducing the fabric conveying speed, avoiding the inefficiency caused by extending the fabric dwell time and reducing the conveying speed in the existing technology, and significantly improving the dyeing and printing efficiency of the fabric.

[0019] 2. This environmentally friendly uniform printing and dyeing equipment for bio-based fabrics incorporates a pressing component. After printing and dyeing, the fabric is squeezed by pressure rollers and guide rollers, and excess dye liquor is squeezed out and flows back into the printing and dyeing box. This effectively prevents the dye liquor from being transported outside with the fabric, thus preventing the dye liquor from polluting surrounding equipment and the environment. It solves the problem of pollution caused by dye liquor flowing out with the fabric without treatment in the existing technology, making the entire printing and dyeing process more environmentally friendly.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides an environmentally friendly uniform dyeing and printing device for the preparation of bio-based fabrics, including a dyeing box 1, a pressing part 2, a moving part 3 and a connecting part 4. The inner cavity of the dyeing box 1 is provided with two symmetrically distributed dyeing rollers 11 for the transfer of fabric in the dyeing box 1. Guide rollers 12 are provided on both sides of the opening of the dyeing box 1 for guiding the fabric in and out of the dyeing box 1.

[0028] Specifically, the clamping components 2 are fixed on both sides of the top of one end of the opening of the printing and dyeing box 1. A pressure roller 13 is connected between the two clamping components 2. The pressure roller 13 is located above one of the guide rollers 12. The pressure roller 13 and the guide roller 12 cooperate to squeeze the fabric after printing and dyeing, squeezing out the excess dye on the fabric. The clamping component 2 includes a convex plate 21 fixed at one end of the top of the opening of the printing and dyeing box 1. A dovetail groove 22 is opened in the middle of one side of the convex plate 21. A movable plate 23 is attached to one side of the convex plate 21. A dovetail slider 24 is fixed on one side of the movable plate 23. The dovetail slider 24 is located in the dovetail groove 22 and is used to drive the movable plate 23 to move vertically up and down. The top of the dovetail slider 24 is connected to the inner top wall of the dovetail groove 22 through a spring 25. The middle of the other side of the movable plate 23 is movably connected to the pressure roller 13 through a pin. The spring 25 can drive the pressure roller 13 to move downward, so that the pressure roller 13 and the guide roller 12 cooperate to play a squeezing role.

[0029] Specifically, the movable component 3 is located at the bottom of the inner cavity of the dyeing box 1. Driven by a driving mechanism located on the outside of the dyeing box 1, the movable component 3 moves to reciprocate and strike the fabric between the two guide rollers 12, thereby improving the dyeing efficiency of the fabric. The movable component 3 includes a motor 31 located in the middle of the lower surface of the dyeing box 1. The motor 31 is the driving mechanism. A reciprocating screw 32 is fixed to the output shaft of the motor 31. One end of the reciprocating screw 32 penetrates the inner bottom wall of the dyeing box 1 and is connected to the dyeing box 1 through a sealed bearing. The end is connected to a connector 4, and the top of the connector 4 is connected to a mounting frame 33. Both ends of the mounting frame 33 are attached to the inner wall of the printing and dyeing box 1 through extension plates, which plays a guiding role, so that the mounting frame 33 can move vertically up and down. Multiple elastic columns 34 are fixed on the upper surface of the mounting frame 33 in a linear array. The elastic columns 34 correspond to the fabric between the two guide rollers 12. The elastic columns 34 can hit the fabric located between the two printing and dyeing rollers 11, increasing the contact area between the fabric and the dye liquor, and improving the printing and dyeing efficiency of the fabric.

[0030] More specifically, the connector 4 is located inside the movable part 3 and is used to connect the drive mechanism and the striking mechanism of the movable part 3, and to ensure the sealing of the drive mechanism. The connector 4 includes two symmetrically arranged arc-shaped plates 41 fixed in the middle of the lower surface of the mounting bracket 33. A connecting sleeve 42 is fixed at the bottom end of the arc-shaped plate 41. The connecting sleeve 42 is connected through the reciprocating screw 32, and the inner wall of the connecting sleeve 42 is adapted to the spiral groove of the reciprocating screw 32 through the protrusion. When the reciprocating screw 32 rotates, it drives the connecting sleeve 42 to move up and down reciprocally. The two arc-shaped plates 41 are connected by a sealing plate 43. The sealing plate 43 is connected to the mounting bracket 33 on the top and the connecting sleeve 42 on the bottom, which can seal the gap between the two arc-shaped plates 41. The bottom end of the connecting sleeve 42 is connected to the inner bottom wall of the printing and dyeing box 1 through an elastic sealing sleeve 44, which is used to seal the end of the reciprocating screw 32 located in the printing and dyeing box 1, while not affecting the up and down movement of the connecting sleeve 42.

[0031] When this device is in operation, the fabric is first wound sequentially around the guide roller 12 at one end of the dyeing box 1, the two dyeing rollers 11 inside the dyeing box 1, and the guide roller 12 at the other end of the dyeing box 1. Finally, it is wound onto the roller shaft for the next process. After winding, the limit of the pressure roller 13 is released, and the pressure roller 13 squeezes the fabric under the action of the spring 25. Then, the dye is injected into the dyeing box 1, and the dye liquor is heated by the heating mechanism inside the dyeing box 1 to maintain the dye liquor at a suitable temperature. Then, the fabric is moved by an external traction mechanism, so that the fabric is dyed in the dyeing box 1. During dyeing, the motor 31 is started. 31 drives the reciprocating screw 32 to rotate. The reciprocating screw 32 cooperates with the connecting sleeve 42 to drive the connecting sleeve 42 to move up and down reciprocally. The connecting sleeve 42 drives the mounting frame 33 to move up and down reciprocally through the arc plate 41, so that the multiple elastic columns 34 on the mounting frame 33 can continuously hit the fabric between the two dyeing rollers 11, increasing the contact area between the fabric and the dye liquor, improving the dyeing efficiency of the fabric, and ensuring that the fabric is uniformly printed and dyed. After printing and dyeing, the fabric is squeezed by the pressure roller 13 and the guide roller 12 to squeeze out the excess dye liquor and flow back into the dyeing box 1, avoiding the overflow of dye liquor and pollution of the surrounding equipment and environment.
