Description

Technical Field

[0001] The invention relates to the technical field of textile cross-rolling, in particular to an auxiliary agent double-dipping and double-cross-rolling integrated machine. Background Art

[0002] As one of the indispensable light industries, the textile industry is closely related to our lives. The textile industry has a huge market. In the textile printing, dyeing and finishing process, the supporting equipment cannot do without the process of padding auxiliaries.

[0003] Currently, the liquid rolling machines on the market are divided into flat rolling, vertical rolling and oblique rolling. Flat rolling / vertical rolling have the problem of uneven deformation of the rollers after pressure is applied. Although oblique rolling is adopted to form a more uniform S-shaped pressure on the cloth surface, it can only be rolled once, or additional machines can be added for more dipping and rolling. There are also three-roller vertical rolling machines that are dipped and rolled twice, but the effect is not good due to the deformation of the rollers under pressure.

[0004] Patent CN114059253B discloses a skew rolling mill, which eliminates the indentation caused by the curling of the cloth edge by first determining the position of the widening roller, and then placing the rolling surface of the rolling roller group close to the widening roller, so that the discharge position of the widening roller is matched with the rolling surface, thereby solving the problem of indentation caused by the curling of the cloth edge.

[0005] The above patent drives the lever arm through a bladder cylinder, so that the auxiliary roller is used as the fulcrum of the lever arm for the lever movement, reducing the overall movement of the roller group. At the same time, it avoids the change of the rolling surface when the roller group is pressed again after the gap is opened, reducing the indentation problem caused by the curling of the cloth edge, but the problem of uneven deformation of the roller after pressurization has not been solved.

[0006] To this end, the present application proposes an integrated machine for double dipping and double oblique rolling of an inclined three-roller rolling mill. Summary of the Invention

For example, "connected" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; it may refer to internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0049] Example 1: Please refer to Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 8 , an additive double-dipping and double-oblique rolling integrated machine, comprising a machine body 1, an oblique three-roller rolling mill unit 2 and a double-tank dipping assembly 3, wherein the oblique three-roller rolling mill unit 2 is installed inside the machine body 1, and the bottom roller 8, the middle roller 9 and the upper roller 10 form an asymmetric oblique triangle layout, a first oblique rolling surface is formed between the middle roller 9 and the bottom roller 8, and a second oblique rolling surface is formed between the middle roller 9 and the upper roller 10, and the pressure distribution on the two oblique rolling surfaces is uniform;

[0050] The bottom roller 8 and the upper roller 10 are composite rubber rollers with a roller diameter of 220-400 mm. The selection of the diameter is positively correlated with the working width. A pressure sensor 29 is installed inside the roller body to monitor the cross-rolling pressure in real time. The middle roller 9 is a mirror stainless steel roller with a surface roughness Ra of less than 0.2 μm and a diameter of 180-300 mm. Circulating cooling water is passed through the interior of the middle roller 9. A water temperature controller 28 is installed inside the roller body to regulate the cooling water temperature.

[0051] The double-tank immersion assembly 3 is installed inside the machine body 1 below the inclined three-roller mill unit 2. The first immersion tank 21 and the second immersion tank 22 are arranged horizontally and side by side. The tank body is made of 316L stainless steel and welded as a whole. The inner wall is polished to prevent additive residue. A porous distribution plate is provided in the tank to allow the additive to penetrate the cloth vertically. The temperature control module 34 has a built-in heating tube and a temperature sensor to control the temperature of the additive.

[0052] Each tank is independently equipped with a refill subassembly, including: a liquid level sensor 20, a refill proportional valve 23, and a refill tube 24, to achieve dynamic closed-loop control of the additive concentration and liquid level. The refill subassembly operates independently, and the refill proportional valve 23 is used to accurately supply different additives to meet various process requirements.

[0053] A pneumatic pressurizing assembly 11 is installed on the upper portion of the machine body 1 to provide pressure for the inclined three-roller rolling mill unit 2 to roll the cloth. A dual cylinder 12 is installed on the outside of the machine body 1 and achieves precise downward pressure on the upper roller 10 through a connecting rod 13. The pressure range of the cylinder 12 is 3-10 tons and is continuously adjustable. The connecting rod 13 is a high-strength alloy steel forging. A digital pressure transmitter 30 is connected to the pressure sensor 29 for signal transmission. The digital pressure transmitter 30 adjusts the pressure value according to process requirements to ensure uniformity of the rolling liquid.

[0054] The body 1 is provided with four opening positions, namely the first opening roller 4, the second opening roller 5, the third opening roller 6 and the fourth opening roller 7. The opening position adopts a modular design and is designed with a quick-change interface. The roller type is changed according to the type of fabric. The woven fabric adopts a bending roller to open the width, and the stretch fabric and knitted fabric adopt a rib roller to open the width, so as to ensure the smooth feeding of the fabric.

[0055] The intelligent control component 27 can control the all-in-one machine to switch between the two working modes of "double dipping and double cross rolling" and "single dipping and single cross rolling". In the "double dipping and double cross rolling" mode, the cloth is sequentially dipped in the first dipping tank 21, squeezed by the first cross rolling surface, and then dipped in the second dipping tank 22. Finally, it is squeezed by the second cross rolling surface and discharged and rewound from the second cloth outlet 18. It is suitable for processes that require two dipping and squeezing.

[0056] A cloth guide roller 25 is provided inside the machine body 1, and a parallel tension frame 26 is installed on the top of the machine body 1. The cloth guide roller 25 and the parallel tension frame 26 work together to maintain the stability of the cloth tension and prevent the cloth from wrinkling and deflecting during the rolling process.

[0057] An intelligent control component 27 is installed on the upper outer wall of the machine body 1. A human-machine interface 33 is flush with the outer wall of the machine body 1. The other side of the human-machine interface 33 is connected to a central control unit 31 and a storage unit 32. The human-machine interface 33 is a touch screen that displays four parameters: pressure, speed, liquid level, and temperature in real time. The parameters in the integrated machine can be automatically adjusted by the central control unit 31. The storage unit 32 can save 50 sets of rolling recipes, and the target parameters can be set by the central control unit 31.

[0058] Furthermore, in the wide-width woven fabric production line, the operator selects the "double immersion and double rolling" mode on the human-machine interface 33 and calls the preset cotton cloth rolling formula in the storage unit 32. The cotton cloth rolling formula is: pressure 6 tons, temperature 45°C and cloth speed 35 m / min. After the cloth enters the machine body 1 from the cloth inlet 16, the bending roller structure of the first opening roller 4 quickly unfolds the cloth curling edge, and then immerses it in the pretreatment auxiliary agent in the first immersion tank 21. The porous distribution plate in the tank ensures that the auxiliary agent penetrates the cloth vertically. The liquid level sensor 20 is linked to the liquid replenishment proportional valve 23 to dynamically maintain the liquid level. After the second flattening by the second opening roller 5, the cloth enters the first oblique rolling surface of the oblique three-roller rolling mill unit 2, the squeezing area formed by the bottom roller 8 and the middle roller 9. At this time, the double cylinder 12 of the pneumatic pressure component 11 accurately pressurizes the upper roller 10 through the high-strength alloy steel connecting rod 13, and the pressure sensor 29 feeds back data to the digital pressure transmitter 30 in real time to stabilize the oblique rolling surface pressure. The error is controlled within ±0.1 tons. After the cloth is squeezed, wrinkles are eliminated by the third opening roller 6 and it is immersed in the dye solution in the second immersion tank 22. The temperature control module 34 keeps the dye solution at a constant temperature of 50°C through the built-in heating tube. Finally, the cloth is squeezed twice through the second oblique rolling surface formed by the middle roller 9 and the upper roller 10. The middle roller 9 made of mirror stainless steel can effectively prevent the cloth from snagging. The temperature of the circulating cooling water in the middle roller 9 is regulated by the water temperature controller 28, which effectively prevents the thermal condensation of the dye. The full-length guide roller 25 and the parallel tension frame 26 work together to maintain the cloth tension. The finished product is output from the second cloth outlet 18, which greatly improves production efficiency, reduces the rolling rate, and reduces the waste of auxiliaries.

[0059] Example 2: Please refer to Figure 1 、 Figure 3 、 Figure 7 and Figure 8 , an additive double-dipping and double-oblique rolling integrated machine, comprising a machine body 1, an oblique three-roller rolling mill unit 2 and a double-tank dipping assembly 3, wherein the oblique three-roller rolling mill unit 2 is installed inside the machine body 1, and the bottom roller 8, the middle roller 9 and the upper roller 10 form an asymmetric oblique triangle layout, a first oblique rolling surface is formed between the middle roller 9 and the bottom roller 8, and a second oblique rolling surface is formed between the middle roller 9 and the upper roller 10, and the pressure distribution on the two oblique rolling surfaces is uniform;

[0060] The machine body 1 is internally provided with a transmission assembly, and a bottom roller motor 14 is connected to the bottom roller 8. The power range of the bottom roller motor 14 is 7.5-15 kW, and the power value is proportional to the working width, ensuring that the integrated machine can operate stably under different widths. The bottom roller motor 14 is provided with a current transformer, and emergency braking is performed when overloaded by 10%. The frequency converter 19 controls the output power of the bottom roller motor 14 to regulate the cloth speed.

[0061] The intelligent control component 27 can control the all-in-one machine to switch between two working modes: "double dipping and double cross-rolling" and "single dipping and single cross-rolling". The "single dipping and single cross-rolling" mode adjusts the cloth rolling path, using only the first dipping tank 21 and the first cross-rolling surface, and discharging from the first cloth outlet 17, which is suitable for a single dipping and rolling process.

[0062] Furthermore, when processing stretch fabrics, the modular opening rollers of the equipment are used to achieve rapid changeover. The technicians replace the first opening roller 4 and the second opening roller 5 with rib rollers through the quick-change interface to adapt to the high elasticity characteristics of the stretch fabric. After the operator selects the "single immersion and single rolling" mode on the human-machine interface 33, the fabric path is shortened to: fabric inlet 16 → first opening roller 4 → first immersion tank 21 → second opening roller 5 → first oblique rolling surface → first fabric outlet 17. The Shore hardness of the composite rubber upper roller 10 is adjusted to 90 degrees. The width of 1.8 m corresponds to a roller diameter of 310 mm. The hydraulic balancing cylinder automatically offsets the deadweight bias. When the fabric speed increases to the limit value of 60 m / min, the current transformer of the bottom roller motor 14 detects load fluctuations, and the frequency converter 19 adjusts the power of the bottom roller motor 14 to 12 within 0.5 seconds. kW, to avoid overload shutdown. During the process, the intelligent control component 27 displays and adjusts four parameters in real time: the pressure sensor 29 feedbacks the oblique rolling surface pressure, the immersion tank liquid level maintains an error of ±2 mm, the dye solution temperature is stable at 48°C, and the cloth speed fluctuation is less than 0.3 m / min. Compared with the traditional vertical padder, this mode ensures the balanced tension of the warp and weft directions of the stretch fabric while greatly reducing the downtime caused by replacing the opening roller body, and there is no problem of positive and negative color of the cloth surface caused by roller deformation.

[0063] Example 3: Please refer to Figure 1 、 Figure 2 and Figure 5 , an additive double-dipping and double-oblique rolling integrated machine, comprising a machine body 1, an oblique three-roller rolling mill unit 2 and a double-tank dipping assembly 3, wherein the oblique three-roller rolling mill unit 2 is installed inside the machine body 1, and the bottom roller 8, the middle roller 9 and the upper roller 10 form an asymmetric oblique triangle layout, a first oblique rolling surface is formed between the middle roller 9 and the bottom roller 8, and a second oblique rolling surface is formed between the middle roller 9 and the upper roller 10, and the pressure distribution on the two oblique rolling surfaces is uniform;

[0064] The double-tank immersion assembly 3 is installed inside the machine body 1 below the inclined three-roller mill unit 2. The double-tank immersion assembly 3 consists of a first immersion tank 21, a second immersion tank 22, a temperature control module 34 and a liquid replenishing subassembly;

[0065] The first immersion tank 21 and the second immersion tank 22 are arranged horizontally and side by side. The tank body is made of 316L stainless steel and welded as a whole. The inner wall is polished to prevent additive residue. A porous distribution plate is provided in the tank to allow the additive to penetrate the cloth vertically. The temperature control module 34 has a built-in heating tube and temperature sensor to control the temperature of the additive in the tank.

[0066] Each tank is independently equipped with a refill subassembly, including: a liquid level sensor 20, a refill proportional valve 23, and a refill tube 24, to achieve dynamic closed-loop control of the additive concentration and liquid level. The refill subassembly operates independently, and the refill proportional valve 23 is used to accurately supply different additives to meet various process requirements.

[0067] Furthermore, in order to handle the step-by-step process of dye-resist and color-fixing agent for knitted fabrics, the double-tank immersion component 3 operates independently: the first immersion tank 21 is injected with dye-resist, and the required temperature is 50°C; the second immersion tank 22 is injected with color-fixing agent, and the required temperature is 30°C. The cloth runs according to the "double immersion and double rolling" path, and the immersion time is 0.8 seconds each. A temperature control module 34 is installed in both tanks. The built-in heating tube and temperature sensor of the temperature control module 34 realize independent regulation of the two temperature zones with an accuracy of ±1°C. The rehydration subassembly accurately replenishes different additives according to the data of the liquid level sensor 20 by the rehydration proportional valve 23 to prevent cross contamination. The adaptive oblique rolling surface of the oblique three-roller rolling mill unit 2 is compatible with the low-tension characteristics of knitted fabrics. The circulating cooling water in the middle rolling roller 9 is adjusted to 20°C to prevent the denaturation of heat-sensitive additives. The intelligent control component 27 displays in real time that the liquid level difference between the two tanks is less than 5 mm and the pressure fluctuation at the rolling point is less than 2%, ensuring that the anti-dyeing agent rolling rate is 65% and the fixing agent rolling rate is 70%. At the end of the process, the inner wall of the 316L stainless steel tank is free of additive residue due to polishing, which shortens the cleaning time when switching recipes.

[0068] Example 4: Please refer to Figure 2 、 Figure 4 、 Figure 5 and Figure 6 , an additive double-dipping and double-oblique rolling integrated machine, comprising a machine body 1, an oblique three-roller rolling mill unit 2 and a double-tank dipping assembly 3, wherein the oblique three-roller rolling mill unit 2 is installed inside the machine body 1, and the bottom roller 8, the middle roller 9 and the upper roller 10 form an asymmetric oblique triangle layout, a first oblique rolling surface is formed between the middle roller 9 and the bottom roller 8, and a second oblique rolling surface is formed between the middle roller 9 and the upper roller 10, and the pressure distribution on the two oblique rolling surfaces is uniform;

The pressure sensor 29 monitors the oblique rolling surface pressure in real time. The middle roller 9 is a mirror stainless steel roller. The bearing seat of the middle roller 9 is equipped with a wedge-shaped gap adjustment block with an adjustment accuracy of 0.1 mm.

[0070] The double-tank immersion assembly 3 is installed inside the machine body 1 below the inclined three-roller mill unit 2. The first immersion tank 21 and the second immersion tank 22 are arranged horizontally and side by side. The tank body is made of 316L stainless steel and welded as a whole.

The digital pressure transmitter 30 is connected to the pressure sensor 29 signal to ensure the uniformity of the rolling liquid.

[0073] Furthermore, when processing high-end sports fabric spandex stretch fabric, the high-tension process compatibility of the equipment was verified, and the cloth tension was increased to 180N. The asymmetric layout of the inclined three-roller rolling mill unit 2 demonstrated its adaptive ability: the composite rubber layer of the bottom roller 8 and the upper roller 10 produced elastic deformation compensation, and the mirrored stainless steel rigid body of the middle roller 9 was fine-tuned by 0.5mm spacing through the wedge-shaped gap adjustment block to ensure that there was no fault in the pressure curve. The double-tank immersion component 3 performed a step-by-step process: the first immersion tank 21 was immersed in the moisture-absorbing and perspiration-releasing agent for 0.8 seconds, and the porous distribution plate increased the agent penetration rate to 99%; the second immersion tank 22 was injected with antibacterial finishing agent, and the temperature control module 34 maintained an active temperature of 40°C. The pneumatic pressure component 11 demonstrated precise response during the high-speed rolling stage of the cloth at a speed of 55 m / min: the cylinder 12 achieved stepless adjustment of the pressure from 3 tons to 8 tons within a stroke of 300 mm, and the connecting rod 13 suppressed the vibration amplitude to 0.05 mm or less, and the finished product has been tested to have an additive penetration uniformity of 96% and a tensile strength loss of less than 2%, breaking through the industry record of high-tension rolling of stretch fabric. The equipment can run continuously for 72 hours, and automatically switches through 50 groups of formulas saved in the storage unit 32. The energy consumption is greatly reduced compared with the three-roller vertical rolling mill.

[0074] Example 5: Please refer to Figure 1 、 Figure 4 、 Figure 5 and Figure 6, an additive double-dipping and double-oblique rolling integrated machine, comprising a machine body 1, an oblique three-roller rolling mill unit 2 and a double-tank dipping assembly 3, wherein the oblique three-roller rolling mill unit 2 is installed inside the machine body 1, and the bottom roller 8, the middle roller 9 and the upper roller 10 form an asymmetric oblique triangle layout, a first oblique rolling surface is formed between the middle roller 9 and the bottom roller 8, and a second oblique rolling surface is formed between the middle roller 9 and the upper roller 10, and the pressure distribution on the two oblique rolling surfaces is uniform;

[0075] The bottom roller 8 and the upper roller 10 are composite rubber rollers, and a pressure sensor 29 is installed in the roller body. The pressure sensor 29 monitors the oblique rolling surface pressure in real time. The middle roller 9 is a mirror stainless steel roller. Circulating cooling water is passed through the interior of the middle roller 9. A water temperature controller 28 is installed inside the roller body to regulate the cooling water temperature.

[0076] The double-tank immersion assembly 3 is installed inside the machine body 1 below the inclined three-roller mill unit 2. The first immersion tank 21 and the second immersion tank 22 are arranged horizontally and side by side. A temperature control module 34 is provided in the tank. The temperature control module 34 has a built-in heating pipe and a temperature sensor to control the temperature of the additive.

[0077] An observation window 35 is provided on the outer wall of the machine body 1. A handle 36 is installed on the observation window 35. The observation window 35, which is hinged to the outer wall of the machine body 1, can be opened by the handle 36 to serve as an inspection door. The observation window 35 is made of tempered glass, which ensures protection while allowing observation of the internal operation of the machine body 1.

[0078] Furthermore, during the operation of the equipment in the northern winter, the low temperature environment tests the performance of the temperature control system. When producing heavy canvas, the "double immersion and double rolling" mode is started. The dye solution in the second immersion tank 22 drops to 12°C due to the ambient temperature. The temperature control module 34 activates the heating tube and cooperates with the temperature sensor in the tank to heat the dye solution to the set value of 55°C within 90 seconds. At the same time, the circulating cooling water in the middle rolling roller 9 starts the antifreeze mode. The water temperature controller 28 increases the water inlet temperature from 5°C to 25°C to avoid condensation on the roller surface affecting the uniformity of the rolling liquid. When the diameter of the pneumatic pressure component 11 is 250 mm, the cylinder 12 is at the maximum stroke of 400 When the upper roller 10 was pressed down by 0.7 tons, the pressure sensor 29 detected that the pressure at the left end of the upper roller 10 increased abnormally by 0.7 tons. The intelligent control component 27 immediately started self-correction: the hydraulic balance cylinder of the upper roller 10 increased the compensation pressure on the right side, and the digital pressure transmitter 30 synchronously adjusted the pressure distribution of the cylinder 12. The fault information was pushed to the human-computer interaction interface 33 in real time. The maintenance personnel opened the observation window 35 through the handle 36 and quickly cleaned it after finding that the roller was frosted. The time taken for this abnormal handling was greatly shortened compared with traditional rolling equipment, and there was no wrinkle or color difference in the cloth, which greatly reduced the losses caused by downtime.

[0079] Working principle: The operator selects the type of cloth to be rolled on the human-machine interface 33. The central control unit 31 automatically sets the target parameters after retrieving the rolling formula from the storage unit 32. The cloth enters the machine body 1 from the cloth inlet 16, and is unfolded and curled by the first opening roller 4. The cloth is then immersed in the caustic soda solution in the first immersion tank 21 for 0.8 seconds. The porous distribution plate in the tank allows the additive to penetrate the cloth vertically. It is flattened for the second time by the second opening roller 5 and enters the first oblique rolling surface between the bottom roller 8 and the middle roller 9. The cylinder 12 applies a pressure of 3-10 tons to remove the excess additive solution in the cloth. After rolling, the cloth passes through the third opening position 6 to eliminate wrinkles and maintain stable tension. The cloth is immersed in the dye solution in the second immersion tank 22 for 0.8 seconds. The temperature control module 34 automatically adjusts the temperature to ensure the activity of the dye, the liquid level sensor 20 controls the liquid replenishment proportional valve 23 to replenish the liquid, and the cloth is finally unfolded through the fourth opening roller 7 to ensure that there is no weft skew. The cloth enters the second oblique rolling surface between the middle rolling roller 9 and the upper rolling roller 10. The water temperature controller 28 adjusts the cooling water temperature. The cylinder 12 pressurizes and removes excess dye from the cloth. The digital pressure transmitter 30 adjusts the pressure distribution in real time according to the data measured by the pressure sensor 29. The rolled cloth is then passed through the guide roller 25 and the parallel tension frame 26 to ensure that the cloth speed and tension match. Finally, the rolled cloth is reeled from the second cloth outlet 18. During the entire operation process, the human-computer interaction interface 33 displays relevant parameters in real time.
