Description

TECHNICAL FIELD

[0001] The utility model relates to cloth processing technical field, especially relate to a kind of compression roller device for chemical fibre cloth processing. BACKGROUND

[0002] In the processing of chemical fibre cloth, compression roller device plays a very key role. Chemical fibre cloth needs to go through multiple complex processes during production, and compression roller device can apply uniform pressure to the cloth, so that it meets the ideal processing standard in thickness, flatness and tightness. Through the rolling of compression roller, the surface of the cloth is smoother, and the internal fiber structure is more compact and orderly. This not only improves the appearance quality of the cloth, but also enhances its physical properties, such as tensile strength and wear resistance, so that the chemical fibre cloth can better meet the needs of subsequent processing and market application. However, compression roller device has many problems in use, among which cloth tension unevenness and deviation are particularly prominent.

[0003] In the processing flow of chemical fibre cloth, the cloth will go through different processing links and be transmitted between multiple devices. The fabric is prone to deviate into the compression roller when being pulled over a long distance between devices, because of the positional accuracy between devices and the self-deviation of the cloth due to elastic difference and uneven thickness. If not intervened, the fabric will be in a non-perpendicular state with the compression roller during rolling, and the pressure on each part of the fabric will be different, resulting in deviation in thickness and flatness and affecting product quality.

[0004] The existing compression roller device generally uses electrical automation control to deal with these problems, but this control method is relatively complex in structure and operation, and the manufacturing cost and subsequent maintenance cost of the device are high. In order to simplify the fabric deviation correction structure, facilitate deviation correction operation and reduce the use cost, the device meets the needs of small and medium-sized enterprises for equipment.

[0009] Further improvement is that the surfaces of the outer sleeve inside the two fixed flaps are respectively provided with movable flaps which can be disengaged and clamped and which can adjust the deviation rectifying distance according to the width of the fabric, and the lower end of the movable flap is provided with a clamping opening with a smaller diameter than the outer diameter of the outer sleeve.

[0010] Further improvement is that the movable flaps are made of hard plastic or soft plastic.

[0011] A further improvement is made to the bracket, which has three sets of pressure roller structures arranged horizontally or staggered vertically. Each pressure roller structure includes an upper pressure roller, a lower pressure roller, a pressure adjusting block, a sealing block, and a threaded drive rod. The two ends of the lower pressure roller are rotatably mounted on the front and rear panels of the bracket. The front and rear panels of the bracket are respectively provided with sliding pressure adjusting grooves above the lower pressure roller. The pressure adjusting block is slidably mounted in the sliding pressure adjusting grooves.

[0016] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0017] 1. This design utilizes a manually adjustable split rod to rotate the worm gear, which in turn drives the turbine. This allows for precise adjustment of the tilt angle between the tension adjusting roller and the alignment roller, thus accurately regulating the fabric tension. In actual production, this effectively prevents the fabric from sagging due to excessive slack, thereby preventing fabric skew caused by looseness and ensuring that the fabric maintains a stable tension state throughout processing. This provides a favorable foundation for subsequent pressure roller processing. After adjustment, the self-locking function of the worm gear simplifies the structure that restricts the autonomous rotation of the tension adjusting roller and the alignment roller.

[0018] 2. After long-term continuous operation of the pressure roller device and the preceding device, wear and tear on the transmission components inevitably occurs, easily leading to speed differences between the two devices. When the transmission speed of the preceding device is greater than that of the pressure roller device, the fabric tension can be flexibly adjusted by changing the tilt angle of the tension regulating roller and the correction roller, or the rotation speed of the pressure roller device can be increased in a timely manner to effectively match the speed difference between the two devices. However, when the transmission speed of the preceding device is less than that of the pressure roller device, the fabric will be stretched taut after the equipment has been running for a period of time. At this time, the damping shaft between the mounting block and the mounting shaft plays a crucial role. It can be forced to rotate under the condition of fabric tension, thus cleverly alleviating the problem of excessive fabric tension. At the same time, the operator can intuitively know the real-time changes in fabric tension by observing the initial tilt angle of the manually adjusted fixing rod and the change in the tilt angle position after the damping shaft is forced to rotate, so as to adjust the speed of the pressure roller device or the preceding device in a timely and accurate manner, comprehensively protecting the integrity and quality of the fabric during the processing.

[0019] 3. The coordinated action of the inner rod, outer sleeve, spiral block, and balance spring allows the correcting roller to automatically adjust according to the actual movement of the fabric. The distance between the spiral block and the outer sleeve is adjusted to compress the balance spring, thus regulating the spring's elastic preload to accommodate fabrics of different weights and thicknesses. The outer sleeve moves back and forth under the influence of the fabric and eventually settles in the middle of the inner rod under the action of the springs on both sides. A greater elastic preload results in a smaller range of fabric deviation and a stronger correcting force, suitable for high-weight fabrics. A smaller elastic preload results in a larger range of deviation, suitable for low-weight, lightweight fabrics. It can adapt to the spontaneous back-and-forth movement of the fabric due to stretching, preventing fabric deformation, and gradually and automatically completes the correction under the balance of the springs on both sides, thus protecting the fabric.

The outer sleeve 23 has movable baffles 28, which are detachably and clampably mounted on the inner surfaces of the two fixed baffles 27, respectively. These movable baffles 28 adjust the correction distance according to the fabric width. Each movable baffle 28 has a clamping opening at its lower end with a diameter smaller than the outer diameter of the outer sleeve 23. The outer surface of the outer sleeve 23 is coated with a silicone coating to increase the static friction of the movable baffles 28, thus limiting their slippage under fabric offset and improving their correction effect. The movable baffles 28 can better adapt to fabrics of different widths, improving the equipment's versatility. The movable baffles 28 are made of either hard or soft plastic to facilitate assembly and disassembly and to enhance friction.

[0028] The support 10 has three sets of pressure roller structures 11 arranged horizontally or staggered vertically.

[0029] Drive structure scheme one: The drive structure includes a motor, a sprocket, and a chain. The housing of the motor is fixedly mounted on the outer side of the bracket 10. The sprocket is located on the outer side of the bracket 10 and is fixedly sleeved on the three lower pressure rollers 30 and the rotating shaft of the motor. The chain is wound around the sprocket.

[0030] Drive structure scheme two: The drive structure includes three motors, the housing of the motor is fixedly disposed on the outer side of the bracket 10, and the rotating shaft of the motor is fixedly connected to the rotating shaft of the motor.

[0031] Both Scheme 1 and Scheme 2 for the drive structure are conventional designs, so they will not be described in detail here.

[0032] The working principle of pressure adjustment and correction of a pressure roller device for processing chemical fiber fabrics:

[0033] The outer fabric is sequentially threaded between the tension adjusting roller 16 and the correction roller, between the upper pressure roller 29 and the lower pressure roller 30 of the three-roller structure 11, and between the output guide clamping roller. By manually adjusting the split rod 20 to rotate the worm gear 19, the turbine 18 is driven to finely adjust the tilt angle between the tension adjusting roller 16 and the correction roller, so that the lower end of the tension adjusting roller 16 and the upper end of the correction roller are pressed against the fabric, thereby adjusting the tension of the fabric and preventing the fabric from becoming too loose and sagging, which would aggravate the fabric deviation. After prolonged use, the transmission components of the pressure roller device and the preceding device wear down, resulting in a speed difference between them. When the transmission speed of the preceding component is greater than that of the pressure roller device, the fabric tension can be adjusted by changing the tilt angle of the tension adjusting roller 16 and the correction roller, or by increasing the rotation speed of the pressure roller device. When the transmission speed of the preceding component is less than that of the pressure roller device, the fabric may become stretched and taut after the equipment has been running for a period of time. This can lead to fabric deformation or even tearing. In this case, the damping shaft 14 between the mounting block 15 and the mounting shaft 13 can be forced to rotate under the tension of the fabric to alleviate the problem of excessive fabric tension. By manually judging the initial tilt angle of the manual adjustment fixing rod 17 and the tilt angle position of the damping shaft 14 after forced rotation, the change in fabric tension can be determined, making it easier to adjust the speed of the pressure roller device or the preceding device to protect the fabric.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
