Description

TECHNICAL FIELD

[0001] The utility model belongs to printing and dyeing device technical field, concretely relates to a kind of high-efficiency printing and dyeing device for knitted fabric production. BACKGROUND

[0002] Printing and dyeing is to apply dyes or pigments to textiles through specific processes, and through a series of physical and chemical processes, the dyes are combined with fibers, so as to form persistent, bright colors and patterns on textiles. Its principle is mainly based on the interaction between dyes and fibers, including adsorption, diffusion, fixation and other processes.

[0003] The utility model with publication number CN221663186U discloses a kind of high-efficiency printing and dyeing device for knitted fabric production, it is driven by motor to stir vane wheel rotation, stir vane wheel rotation stirs dye in dye pool, can promote dye mixing, avoid the emergence of uneven dye condition, simultaneously, water pump extracts dye in one side dye pool into another dye pool, this leads to the liquid level of latter to rise, reflux pipe can conduct dye backflow, so that dye is circulated between two dye pools, make the dye color consistent in two dye pools, guarantee the effect of double-sided printing and dyeing, but its use, since dye pool is deep, it will remain more dye in its dye pool cannot be dipped by printing and dyeing roller, after finishing work, this part of dye is difficult to clean out, and it is driven by water pump to circulate dye in two groups of dye pool, largely, it will lead to the liquid level of each dye pool to be undulating, lead to printing and dyeing roller cannot be dipped evenly even cannot be dipped, affect printing and dyeing effect UTILITY MODEL CONTENT

[0004] In view of the above problems, the utility model aims to provide a kind of high-efficiency printing and dyeing device for knitted fabric production, can guarantee that the liquid level in dye dipping groove is stably kept in a certain range, so as to guarantee that printing and dyeing roller can dip dye, and the residual amount of dye in dye dipping groove is smaller, avoid waste situation, also facilitate subsequent cleaning work.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency dyeing and printing device for knitted fabric production, comprising a machine casing, with an inlet and a outlet at both ends of the machine casing, and a first guide roller, a front dyeing roller group, a back dyeing roller group, a fourth guide roller, and a reversing roller mechanism on the inner side of the machine casing. A reversing roller mechanism is located between the front and back dyeing roller groups on the inner side of the machine casing. Dye dipping tanks are installed below both the front and back dyeing roller groups on the inner side of the machine casing. A scraper is installed at the top of each dye dipping tank, and a liquid inlet cylinder is installed at the bottom of each dye dipping tank. A third hydraulic telescopic rod is installed inside the liquid inlet cylinder, and a piston is installed at the top of the piston rod of the third hydraulic telescopic rod. A liquid delivery pipe is connected to the back of the liquid inlet cylinder, and the other end of the liquid delivery pipe is connected to a dye storage tank. A first motor is also located at the bottom of the dye storage tank, and the output end of the first motor is fixedly connected to a stirring paddle. A liquid level sensor is installed at the top of the liquid inlet cylinder.

[0006] The beneficial effects of this invention are as follows: During printing and dyeing, dye is injected into the dye storage tank. Under the action of gravity, the dye flows into the liquid delivery pipe. The third hydraulic telescopic rod drives the piston to descend, releasing the seal on the liquid delivery pipe, allowing the dye in the liquid delivery pipe to be injected into the liquid inlet cylinder. As the amount of dye entering increases, the liquid level gradually rises into the dye dipping tank, enabling the printing and dyeing rollers to contact the dye for over-dipping. The liquid level height inside the dye dipping tank is monitored by a liquid level sensor. When the liquid level inside the dye dipping tank reaches a certain height, the control device automatically... The third hydraulic telescopic rod drives the piston upward, sealing the liquid delivery pipe and stopping the input of dye into the inlet cylinder. The second motor drives the dyeing roller to rotate. After the dyeing roller picks up the dye, a scraper smooths the dye on the rotating roller, and then the dye is coated onto the fabric surface. When the level sensor detects that the liquid level in the dye dipping tank has dropped to a certain position, the control device controls the third hydraulic telescopic rod to drive the piston downward, allowing the dye in the delivery pipe to replenish the inlet cylinder and the dye dipping tank, ensuring the dye dipping tank remains in good working order. The liquid level in the dyeing tank is kept stable within a certain range to ensure that the dyeing roller can pick up the dye. During continuous operation, the first motor can be controlled to drive the stirring paddle to rotate, which stirs the dye in the dye storage tank, preventing the dye from settling due to static conditions and maintaining the uniformity of the dye composition. This ensures that the dye composition in the dye inlet cylinder and dye dipping tank entering through the liquid delivery pipe is uniform, and because the volume of the dye dipping tank and liquid inlet cylinder is relatively small, the dye in the dye dipping tank and liquid inlet cylinder can be consumed quickly, which also prevents the dye from settling in the dye dipping tank and liquid inlet cylinder. The phenomenon is that when the dyeing and printing work is about to end, the third hydraulic telescopic rod can be controlled to drive the piston to rise until the top of the piston is flush with the bottom of the dye dipping tank, so that all the dye enters the dye dipping tank and is picked up by the dyeing roller. Because the bottom of the dyeing roller is close to the bottom of the dye dipping tank, the amount of dye residue in the dye dipping tank is small, avoiding waste and facilitating subsequent cleaning. During cleaning, simply open the valve to inject cleaning water into the dye dipping tank, the liquid inlet cylinder and the dye storage tank for cleaning. The cleaning wastewater can be discharged through the valve.

[0007] As a further improvement to the above technical solution: the front dyeing roller group and the back dyeing roller group include a dyeing roller, a second guide roller, and a third guide roller rotatably mounted inside the machine housing. The inside of the machine housing is also provided with a clamping roller bracket. The top of the clamping roller bracket is provided with a first hydraulic telescopic rod. The top of the first hydraulic telescopic rod is equipped with a first clamping roller mounting frame. The first clamping roller is rotatably mounted inside the first clamping roller mounting frame. A second motor is installed on the side of the machine housing. The output end of the second motor is connected to the dyeing roller.

[0008] In use, the fabric is pulled into the machine housing from the feed inlet, passes the top of the first guide roller, turns downward, goes around the bottom of the second guide roller in the front dyeing roller group, and then goes around the top of the dyeing roller. The fourth hydraulic telescopic rod drives the second clamping roller mounting frame to descend, so that the second clamping roller cooperates with the dyeing roller to clamp the fabric, making the fabric stick to the dyeing roller. Then the fabric passes between the first clamping roller and the third guide roller, and the first hydraulic telescopic rod drives the first clamping roller mounting frame together with the first clamping roller to rise, cooperate with the third guide roller to clamp the fabric. After the fabric is flipped, it follows the same path as when it entered the front dyeing roller group, going around the bottom of the second guide roller in the reverse dyeing roller group and then between the dyeing roller and the second clamping roller. After entering between the first clamping roller and the third guide roller, it goes around the top of the fourth guide roller and is output from the discharge port.

[0009] To hold the fabric in place during the printing and dyeing process:

[0010] As a further improvement to the above technical solution: a fourth hydraulic telescopic rod is installed inside the machine housing above the dyeing roller, a second clamping roller mounting frame is installed at the bottom of the fourth hydraulic telescopic rod, and a second clamping roller is rotatably installed on the inner side of the second clamping roller mounting frame.

[0011] The beneficial effect of this improvement is that when the fabric passes over the dyeing roller, the second clamping rod is pushed towards the dyeing roller by the fourth hydraulic telescopic rod, and the fabric is clamped in cooperation with the dyeing roller to avoid wrinkles in the fabric.

[0012] For the direction of the fabric:

[0013] As a further improvement to the above technical solution: the reversing roller mechanism includes a first bracket and a second bracket fixed inside the chassis. A first reversing roller mounting frame is installed at one end of the first bracket, and a first reversing roller is installed on the inner side of the first reversing roller mounting frame. One end of the second bracket is fixed to a second hydraulic telescopic rod, and one end of the second hydraulic telescopic rod is fixed to a second reversing roller mounting frame. A second reversing roller is rotatably mounted on the inner side of the second reversing roller mounting frame.

[0014] The beneficial effects of this improvement are as follows: after the fabric leaves the space between the first clamping roller and the third guide roller in the front dyeing roller group, the fabric is twisted and enters the space between the first reversing roller and the second reversing roller. The second reversing roller mounting frame and the second reversing roller are driven by the second hydraulic telescopic rod to move closer to the first reversing roller. The fabric is clamped by the second reversing roller and the first reversing roller. Then the fabric is twisted again to complete the flipping of the fabric, so as to meet the dyeing needs of the reverse side after the other side of the fabric enters the reverse dyeing roller group.

[0015] For the support of the dye storage tank:

[0016] As a further improvement to the above technical solution: the bottom of the dye storage tank is equipped with supporting feet.

[0017] The beneficial effect of this improvement is that the support feet are used to support the dye storage tank.

[0018] To ensure proper drainage of wastewater during the cleaning of this device:

[0019] As a further improvement to the above technical solution: a valve is connected to one side of the liquid delivery pipeline.

[0020] The beneficial effect of this improvement is that the valve opens when cleaning the dye dipping tank, the liquid inlet cylinder, and the dye storage tank to discharge wastewater.

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0033] like Figures 1-6 As shown, a high-efficiency dyeing and printing device for knitted fabric production includes a housing 1. The housing 1 has an inlet 2 and an outlet 14 at its two ends. Inside the housing 1 are a first guide roller 3, a front dyeing roller group 4, a back dyeing roller group 5, a fourth guide roller 13, and a reversing roller mechanism 15. The reversing roller mechanism 15 is located between the front dyeing roller group 4 and the back dyeing roller group 5 inside the housing 1. Dye-dipping tanks 23 are installed below both the front dyeing roller group 4 and the back dyeing roller group 5 on the inside of the housing 1. The top of the dye-dipping tank 23... A scraper 24 is installed in the part, and a liquid inlet cylinder 25 is installed at the bottom of the dye dipping tank 23. A third hydraulic telescopic rod 26 is installed on the inner side of the liquid inlet cylinder 25. A piston 27 is installed at the top of the piston rod of the third hydraulic telescopic rod 26. A liquid delivery pipe 28 is connected to the back of the liquid inlet cylinder 25. The other end of the liquid delivery pipe 28 is connected to the dye storage tank 29. A first motor 30 is also provided at the bottom of the dye storage tank 29. The output end of the first motor 30 is fixedly connected to the stirring paddle 31. A liquid level sensor 32 is installed at the top of the liquid inlet cylinder 25.

[0034] During the dyeing process, dye is injected into the dye storage tank 29. Under gravity, the dye flows into the liquid delivery pipe 28. The third hydraulic telescopic rod 26 drives the piston 27 to descend, releasing the seal on the liquid delivery pipe 28. This allows the dye in the liquid delivery pipe 28 to be injected into the liquid inlet cylinder 25. As the amount of dye entering increases, the liquid level gradually rises into the dye dipping tank 23, allowing the dyeing roller 6 to contact the dye and perform over-dipping. The liquid level sensor 32 monitors the liquid level inside the dye dipping tank 23. When the liquid level inside the dye dipping tank 23 reaches a certain height, the control device 37 automatically controls... The third hydraulic telescopic rod 26 drives the piston 27 to rise, sealing the liquid delivery pipe 28 and stopping the input of dye into the liquid inlet cylinder 25. The second motor 33 drives the dyeing roller 6 to rotate. After the dyeing roller 6 picks up the dye, the doctor blade 24 scrapes the dye off the rotating roller 6, and the dye is then coated onto the fabric surface. When the level sensor 32 detects that the liquid level in the dye dipping tank 23 has dropped to a certain position, the control device 37 controls the third hydraulic telescopic rod 26 to drive the piston 27 to descend, allowing the dye in the liquid delivery pipe 28 to be replenished into the liquid inlet cylinder 25, and the dye dipping... Inside the dyeing tank 23, during continuous operation, the first motor 30 can be controlled to drive the stirring paddle 31 to rotate. The stirring paddle 31 stirs the dye in the dye storage tank 29, preventing the dye from settling due to static conditions and maintaining the uniformity of the dye composition. This ensures that the dye composition in the inlet cylinder 25 and dye dipping tank 23, which enter through the liquid delivery pipe 28, is uniform. Since the volumes of the dye dipping tank 23 and inlet cylinder 25 are relatively small, the dye in these tanks can be consumed quickly, preventing dye deposition. This process is effective when the dyeing process is about to end. During operation, the third hydraulic telescopic rod 26 can be controlled to drive the piston 27 to rise until the top of the piston 27 is flush with the bottom of the dye dipping tank 23, so that all the dye enters the dye dipping tank 23 and is picked up by the dyeing roller 6. Since the bottom of the dyeing roller 6 is close to the bottom of the dye dipping tank 23, the amount of dye residue in the dye dipping tank 23 is small, avoiding waste and facilitating subsequent cleaning. During cleaning, only the valve 38 needs to be opened to inject cleaning water into the dye dipping tank 23, the liquid inlet cylinder 25 and the dye storage tank 29 for cleaning. The cleaning wastewater can be discharged through the valve 38.

[0035] The front dyeing roller group 4 and the back dyeing roller group 5 include a dyeing roller 6, a second guide roller 7, and a third guide roller 8 rotatably mounted inside the machine housing 1. The machine housing 1 is also provided with a clamping roller bracket 9. The top of the clamping roller bracket 9 is provided with a first hydraulic telescopic rod 10. The top of the first hydraulic telescopic rod 10 is equipped with a first clamping roller mounting frame 11. The inner side of the first clamping roller mounting frame 11 is rotatably mounted with a first clamping roller 12. The side of the machine housing 1 is equipped with a second motor 33. The output end of the second motor 33 is connected to the dyeing roller 6.

[0036] In use, the fabric is pulled into the machine housing 1 from the feed inlet 2, passes over the top of the first guide roller 3, turns downwards, goes around the bottom of the second guide roller 7 in the front dyeing roller group 4, and then goes around to the top of the dyeing roller 6. The fourth hydraulic telescopic rod 34 is then controlled to drive the second clamping roller mounting frame 35 to descend, causing the second clamping roller 36 to cooperate with the dyeing roller 6 to clamp the fabric, making the fabric adhere tightly to the dyeing roller 6. The fabric then passes between the first clamping roller 12 and the third guide roller 8, and the first hydraulic... The telescopic rod 10 drives the first clamping roller mounting frame 11 and the first clamping roller 12 to rise, and cooperates with the third guide roller 8 to clamp the fabric. After the fabric is flipped, it passes through the same path as entering the front dyeing roller group 4, so that the fabric passes under the second guide roller 7 in the reverse dyeing roller group 5 and enters between the dyeing roller 6 and the second clamping roller 36, then between the first clamping roller 12 and the third guide roller 8, and after passing over the fourth guide roller 13, it is output from the discharge port 14.

[0037] Inside the housing 1, above the printing roller 6, a fourth hydraulic telescopic rod 34 is installed. A second clamping roller mounting frame 35 is installed at the bottom of the fourth hydraulic telescopic rod 34. A second clamping roller 36 is rotatably installed on the inner side of the second clamping roller mounting frame 35.

[0038] When the fabric passes over the dyeing roller 6, the second clamping rod 36 is pushed toward the dyeing roller 6 by the fourth hydraulic telescopic rod 34, and works with the dyeing roller 6 to clamp the fabric and prevent wrinkles from forming.

[0039] The reversing roller mechanism 15 includes a first bracket 16 and a second bracket 19 fixed inside the housing 1. A first reversing roller mounting frame 17 is installed at one end of the first bracket 16, and a first reversing roller 18 is installed inside the first reversing roller mounting frame 17. One end of the second bracket 19 is fixed to a second hydraulic telescopic rod 20, and one end of the second hydraulic telescopic rod 20 is fixed to a second reversing roller mounting frame 21. A second reversing roller 22 is rotatably mounted on the inner side of the second reversing roller mounting frame 21.

[0040] After the fabric leaves the space between the first clamping roller 12 and the third guide roller 8 in the front printing roller group 4, the fabric is twisted 90 degrees and enters the space between the first reversing roller 18 and the second reversing roller 22. The second reversing roller mounting frame 21 and the second reversing roller 22 are driven by the second hydraulic telescopic rod 20 to move closer to the first reversing roller 18. The fabric is clamped by the second reversing roller 22 and the first reversing roller 18. Then the fabric is twisted 90 degrees to complete the flipping of the fabric, so as to meet the printing and dyeing needs of the reverse side after the other side of the fabric enters the reverse printing roller group 5.

[0041] The bottom of the dye storage tank 29 is equipped with supporting feet.

[0042] The support feet are used to support the dye storage tank 29.

[0043] A valve 38 is connected to one side of the liquid delivery pipe 28.

[0044] Valve 38 is opened when cleaning the dye dipping tank 23, the liquid inlet cylinder 25, and the dye storage tank 29 to discharge wastewater.

[0045] A control device 37 is installed on the side of the chassis 1.

[0046] The control device 37 is equipped with a PLC controller inside, and a touch screen is also provided on the front of the control device 37. The operation interface is displayed and the device is controlled through the touch screen.

[0047] The working principle and usage process of this utility model are as follows: When using this device, the fabric is pulled into the machine housing 1 from the feed inlet 2, passes the top of the first guide roller 3, turns downward, goes around the bottom of the second guide roller 7 in the front dyeing roller group 4, and then goes around to the top of the dyeing roller 6. The fourth hydraulic telescopic rod 34 drives the second clamping roller mounting frame 35 to descend, so that the second clamping roller 36 cooperates with the dyeing roller 6 to clamp the fabric, making the fabric stick to the dyeing roller 6. Then the fabric passes between the first clamping roller 12 and the third guide roller 8, and the first hydraulic telescopic rod 10 drives the first clamping roller mounting frame 11 together with the first clamping roller 12 to rise, cooperate with the third guide roller 8 to clamp the fabric. Then the fabric is twisted 90 degrees and enters the first reversing roller 18 and the second... Between the reversing rollers 22, the second reversing roller mounting frame 21 and the second reversing roller 22 are driven by the second hydraulic telescopic rod 20 to approach the first reversing roller 18. The fabric is clamped by the second reversing roller 22 and the first reversing roller 18, and then the fabric is twisted 90 degrees to complete the flipping of the fabric. Following the same path as entering the front dyeing roller group 4, the fabric passes under the second guide roller 7 in the reverse dyeing roller group 5 and enters between the dyeing roller 6 and the second clamping roller 36, then between the first clamping roller 12 and the third guide roller 8, and after passing over the fourth guide roller 13, it is output from the discharge port 14. After the fabric is dyed on one side by the dyeing roller 6 in the front dyeing roller group 4, the reversing roller mechanism 15 completes a 180-degree twist. After turning, the dye enters the reverse dyeing roller group 5, where the dyeing roller 6 dyes the other side of the fabric, thus achieving continuous synchronous double-sided dyeing. During dyeing, dye is injected into the dye storage tank 29. Under gravity, the dye flows into the liquid delivery pipe 28. The third hydraulic telescopic rod 26 drives the piston 27 to descend, releasing the seal on the liquid delivery pipe 28, allowing the dye in the liquid delivery pipe 28 to be injected into the liquid inlet cylinder 25. As the amount of dye entering increases, the liquid level gradually rises into the dye dipping tank 23, allowing the dyeing roller 6 to contact the dye and over-dip it. The liquid level sensor 32 monitors the liquid level inside the dye dipping tank 23. When the liquid level inside the dye dipping tank 23 reaches a certain height... The control device 37 automatically controls the third hydraulic telescopic rod 26 to drive the piston 27 to rise, sealing the liquid delivery pipe 28 and stopping the input of dye into the liquid inlet cylinder 25. The second motor 33 drives the dyeing roller 6 to rotate. After the dyeing roller 6 picks up the dye, the doctor blade 24 scrapes the dye off the rotating roller 6, and the dye is then coated onto the fabric surface. When the level sensor 32 detects that the liquid level in the dye dipping tank 23 has dropped to a certain position, the control device 37 controls the third hydraulic telescopic rod 26 to drive the piston 27 to fall, allowing the dye in the liquid delivery pipe 28 to replenish the liquid inlet cylinder 25 and the dye dipping tank 23. During continuous operation, the first motor 30 can be controlled to drive the stirring paddle 31 to rotate.The dye in the dye storage tank 29 is stirred by the stirring paddle 31 to prevent the dye from settling due to static conditions, thus maintaining the uniformity of the dye composition. This ensures that the dye composition in the inlet cylinder 25 and dye dipping tank 23, which enter through the liquid delivery pipe 28, is uniform. Since the volumes of the dye dipping tank 23 and inlet cylinder 25 are relatively small, the dye in these tanks can be consumed quickly, preventing dye deposition. When the dyeing process is about to end, the piston can be driven by the third hydraulic telescopic rod 26. Piston 27 rises until its top is flush with the bottom of dye-dipping tank 23, allowing all dye to enter the tank and be picked up by printing roller 6. Because the bottom of printing roller 6 is close to the bottom of dye-dipping tank 23, the amount of dye residue in the tank is small, avoiding waste and facilitating subsequent cleaning. During cleaning, simply open valve 38 to inject cleaning water into dye-dipping tank 23, inlet cylinder 25, and dye storage tank 29. Cleaning wastewater is discharged through valve 38.
