Description
Technical Field
[0001] The utility model relates to the technical field of impregnation and rolling equipment, in particular to a double-drive uniform rolling vehicle. Background Art
[0002] The padder is mainly used for rolling water or dipping working solution. During the washing process and before the drying process, the excess water on the fabric is removed as much as possible to reduce the consumption of heat energy by water. The removal of liquid should be uniform and the efficiency of liquid rolling should be high. Dipping is to roll the working solution (such as acid, alkali, bleaching solution, dyeing solution, resin finishing solution, etc.) into the fabric and remove the excess solution. The efficiency of liquid rolling should be high and the uniformity of liquid rolling should be good. The padder is composed of rollers, a pressure device, an expansion device, a transmission system, a frame, a safety protection device and an automatic control system. The liquid rolling mill also includes a liquid rolling tank. Among them, the uniform padder is a flat-width dipping equipment that can compensate for the deflection of the rollers to obtain a uniform liquid rate in the width of the fabric. At the same time, a certain residual rate must be guaranteed after the fabric is dipped.
[0003] There are many factors that affect the uniformity of the rolling fluid, such as rolling pressure, roller surface hardness and roller stiffness. The roller is characterized by a rotating shell and a fixed mandrel. The inner wall of the roller and the mandrel are separated by a sealing strip into hydraulic high-pressure and low-pressure areas. The radial and axial sealing structures at both ends ensure stable hydraulic pressure. The roller structure is a seamless steel tube covered with nitrile rubber.
[0004] There are usually two rollers. When the dyed cloth is discharged, there is friction between the two rollers. The dyed cloth passes between the two rollers, squeezing out the excess solution in the dyed cloth. The rollers of the current uniform roller are usually driven by a single motor. The driving force of the two rollers is insufficient, the squeezing force between the two rollers is insufficient, the squeezing speed is slow, the efficiency is low, and it is difficult to ensure the liquid carrying rate. Utility Model Content

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A dual-drive uniform rolling mill comprises a rolling trough, in which a cloth guide roller group is arranged, the rolling trough is connected with one side of a discharging trough, a filtrate roller group is arranged in the discharging trough, an outlet is opened on the other side of the discharging trough, a rolling roller group is arranged at the outlet, the cloth guide roller group, the filtrate roller group and the rolling roller group are arranged in parallel, the rolling roller group comprises two parallel rollers, each roller is connected to a cloth rolling motor, each roller rotates under the drive of the corresponding cloth rolling motor, and the two rollers rotate synchronously.

[0010] By adopting the above structural scheme, the position of the bottom end of the swing arm is adjusted by a linear fine-tuning device. After the swing arm rotates and balances, the position of the top end of the swing arm can be fine-tuned, thereby adjusting the position of the swing roller and the pressure between the swing roller and another roller, thereby ensuring the liquid carrying rate and reducing energy consumption.
[0011] As a preferred implementation method of a dual-drive uniform rolling mill, one end of the swing arm connected to the linear fine-tuning device is connected to one side of the flexible member, and the other side of the flexible member is connected to the outer shell of the discharge trough.

One end of the worm is connected to the swing arm, and the worm can slide relative to the outer shell of the discharge trough in the length direction of the worm.
[0012] By adopting the above structural scheme, the worm gear structure can not only achieve the effect of precise adjustment, but also has a self-locking function, so that the fine-tuning process of the swing arm is relatively stable, and the swing arm can stably maintain the posture after fine-tuning.
[0013] As a preferred implementation of a dual-drive uniform rolling mill, the moving distance of the worm is ±1 mm.
[0014] By adopting the above structural solution, only the position of the swing roller is finely adjusted.
[0015] As a preferred implementation method of a dual-drive uniform rolling mill, it also includes a liquid level control system, which includes a liquid level meter, which is located in the rolling trough.

The liquid level regulator controls the opening of the electric regulating valve according to the liquid level height data, thereby controlling the flow of fresh dye solution entering the rolling trough, ensuring the stability of the liquid level in the rolling trough, and eliminating the front and back color difference of the dyed cloth caused by the change of the dye solution level.

[0028] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the utility model will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0029] Reference Figure 1-3 This embodiment provides a dual-drive uniform rolling mill, including a rolling trough 5, a side wall of which is provided with a cloth inlet, a cloth guide roller group 7 is provided in the rolling trough 5, and the cloth guide roller group 7 includes a steel roller and three rubber rollers, the axial directions of the steel roller and the three rubber rollers are all arranged horizontally, and the steel roller and the three rubber rollers are in the same vertical plane. The top of the rolling trough 5 is connected to the bottom of the discharge trough 6, and a filtrate roller group 8 is provided in the discharge trough 6.
[0030] An outlet is provided at the top of the discharge trough 6, and a roller group 1 is provided at the outlet. The cloth guide roller group 7, the filtrate roller group 8 and the roller group 1 are arranged in parallel. The roller group 1 includes two rollers arranged in parallel, each roller is connected to a cloth rolling motor, each roller rotates under the drive of the corresponding cloth rolling motor, and the two rollers rotate synchronously. A reducer is connected between each roller and the corresponding cloth rolling motor.
[0031] One of the rollers in the roller group 1 is a swing roller 11, which is connected to one end of the swing arm 2. The middle part of the swing arm 2 is hinged to the outer shell of the discharge trough 6, and the hinge shaft is arranged parallel to the swing roller 11; the other end of the swing arm 2 is connected to the linear fine-tuning device 3. The linear fine-tuning device 3 includes a worm and a worm wheel, which are meshed with each other. The worm is arranged perpendicular to the axial direction of the swing roller 11. One end of the worm is connected to the swing arm 2. The worm can slide relative to the outer shell of the discharge trough 6 in the length direction of the worm. The rotation of the worm wheel can drive the worm to move in the length direction. The moving distance of the worm is ±1mm, thereby driving the swing arm 2 to perform fine-tuning, thereby adjusting the pressure between the swing roller 11 and another roller. In this way, the end of the swing arm 2 can move linearly in a direction perpendicular to the axial direction of the roller under the drive of the linear fine-tuning device 3; the swing roller 11 can approach or move away from another roller under the drive of the swing arm 2. One end of the swing arm 2 connected to the linear fine-tuning device 3 is connected to one side of the flexible part 4, and the other side of the flexible part 4 is connected to the outer shell of the discharge trough 6. The flexible part 4 is made of rubber, and the flexible part 4 has good flexibility. It can compensate for the small misalignment between the small swing arc of the swing arm 2 and the small linear movement of the worm, and maintain the stability of the bottom end of the swing arm 2.
[0032] This embodiment also includes a liquid level control system, which includes a liquid level meter, which is located in the rolling trough 5. The liquid level meter is electrically connected to the liquid level regulator, which is electrically connected to the electric regulating valve. The electric regulating valve is located on the pump-out pipe of the dye pump, the pump-out pipe of the dye pump is connected to the rolling trough 5, and the pump-in pipe of the dye pump is connected to the dye box, which is used to store the dye.
[0033] This embodiment Figure 1 The bold dotted line in the figure represents the dyed cloth, which is introduced into the material feeding trough 5 from the cloth inlet of the material feeding trough 5 and discharged from between the roller groups 1 in the material discharging trough 6.
[0034] The working principle of this embodiment is:
[0035] When in use, the cloth to be dyed is introduced into the rolling trough 5 from the cloth inlet of the rolling trough 5. The cloth feeding method is single-width flat cloth feeding. The cloth to be dyed bypasses the cloth guide roller group 7 and is immersed and rolled more in the rolling trough 5. The liquid level gauge in the rolling trough 5 can detect the liquid level of the dye solution in the rolling trough 5. The liquid level gauge can transmit the liquid level data to the liquid level regulator. The liquid level regulator controls the opening of the electric regulating valve according to the liquid level data, thereby controlling the flow of fresh dye solution entering the rolling trough 5, ensuring the stability of the liquid level in the rolling trough 5, and eliminating the front and back color difference of the dyed cloth caused by the change of the dye solution level. After being led out from the top of the cloth guide roller group 7, the dyed cloth enters the filtrate roller group 8. The filtrate roller group 8 includes two filtrate rollers. The dyed cloth is in an "S" shape in the filtrate roller group 8. The rotation direction of the two filtrate roller groups 8 is opposite to the moving direction of the dyed cloth. After the dyed cloth is discharged from the filtrate roller group 8, it enters the roller group 1 above. The roller group 1 includes two individually driven rollers. The two rollers run synchronously according to the analog quantity to ensure the liquid carrying rate of the dyed cloth and ensure that the liquid in the dyed cloth can be evenly distributed. The roller is a key component of the uniform rolling car. The roller shell rotates and the core shaft is fixed. The cloth rolling motor is used to drive the roller shell. The outside of the roller is wrapped with a sealed rubber bladder. By pressurizing and depressurizing the bladder, the contact area of the rubber between the two rollers and the pressure between the two rollers can be controlled. At the same time, since the pressure required for dyed cloth of different materials is different, when the roller cannot meet the requirement, the linear fine-tuning device 3 is used to control the number of revolutions and the rotation angle of the worm gear, so that the bottom end of the swing arm 2 can be fine-tuned within the range of ±1mm (the zero point position of the ±1mm adjustment range is the predetermined standard installation position). Since the bottom end of the swing arm 2 is connected to the outer shell of the discharge trough 6 by the flexible part 4, the small swing arc of the swing arm 2 and the small linear movement of the worm will not interfere with each other. Therefore, the position of the top end of the swing arm 2 is fine-tuned, that is, the position of the swing roller 11 is fine-tuned, and the contact area of the rubber between the two parallel rollers is increased or decreased, thereby ensuring the liquid carrying rate and reducing energy consumption.
[0036] The double-drive uniform padder in this embodiment can be operated in conjunction with a washing machine. After the dyed cloth is discharged from the roller group 1, it is introduced into the washing machine to form a wet short steaming process.
[0037] Those skilled in the art should understand that the rolling trough 5 and the discharging trough 6 are structures with troughs.
[0038] There is still a technical problem in the prior art that the roller cannot meet the pressure required for uniform liquid squeezing of the dyed cloth due to factors such as roller aging and changes in the material of the dyed cloth. Therefore, this embodiment also realizes fine-tuning of the swing roller 11 through the linear fine-tuning device 3 to increase or decrease the contact area of the rubber between the two parallel rollers. Compared with the prior art, this embodiment can further ensure the liquid carrying rate and reduce energy consumption.
[0039] In this embodiment, the mandrel of the swing roller 11 can be slidably mounted on the outer shell of the discharge chute 6, and the mandrel of the swing roller 11 is connected to the top of the swing arm 2, and the sliding direction is the swing direction of the swing arm 2. The sliding amplitude of the swing roller 11 is small, and when the swing arm 2 swings under the action of the linear fine-tuning device 3, the position of the swing roller 11 can be fine-tuned. In another embodiment, the mandrel of the swing roller 11 can be mounted on the top of the swing arm 2, and when the swing arm 2 swings under the action of the linear fine-tuning device 3, the swing arm 2 can directly drive the swing roller 11 to fine-tune its position.
[0040] In this embodiment, a spring is connected between the swing arm 2 and the housing of the discharge chute 6 .
[0041] Those skilled in the art should understand that the setting of the swing arm 6 and the linear fine-tuning device 3 cannot interfere with the entry and exit of the dyed cloth. The swing arm 6 and the linear fine-tuning device 3 can be installed on the outer side wall of the outer shell of the discharge trough 6, and the core shaft of the swing roller 11 extends out of the outer shell of the discharge trough 6 and is connected to the top of the swing arm 6. Furthermore, the swing arm 6 and the linear fine-tuning device 3 can be covered with a dustproof protective cover.
[0042] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
