Description

Technical Field

[0001] The utility model belongs to the field of pressure roller driving, in particular to a pressure roller device for a winding mechanism of a slitting machine. Background Art

[0002] After the slitting machine cuts the large roll of material as needed, it needs to be rewound. During the rewinding process, in order to prevent the roll from being loose, the pressure roller needs to be pressed by the rewinding roller throughout the process. The traditional pressure roller usually uses the deadweight of the pressure roller to achieve the state that the pressure roller always presses the rewinding roller. Now there are also some pressure roller driving devices that can adjust the pressure of the pressure roller. In order to adapt to the continuous thickening of the roll during the winding process and to better keep the pressure change of the pressure roller on the rewinding roller from being too large, this pressure roller driving device usually drives the pressure roller to retreat a corresponding distance after the roll reaches a certain thickness, and then repeats this retreat process until the rewinding is completed. The proximity switch will be used in the middle, which is a step-by-step retreat. However, because the pressure roller will instantly leave the rewinding roller a distance when retreating, the pressure of the pressure roller on the rewinding roller will be in a state of gradually increasing from small to large during the period before the next retreat, which will cause the tightness of the rewinding of the roll to be different from front to back in this process, which will affect the overall quality of the roll. Therefore, people hope to find a method that can not only provide an adjustable pressure roller pressure to the winding roller, but also ensure that the pressure roller pressure remains substantially unchanged in real time. Utility Model Content

[0003] The utility model aims to provide a pressure roller device for a slitting machine winding mechanism which has sensitive and accurate adjustment and can adapt to the winding of different coils.

[0004] The utility model is realized by the following technical solutions:

[0005] The pressure roller device for the winding mechanism of the slitting machine is used to be arranged next to the winding device to press the winding roller during winding. The pressure roller device includes a moving trolley driven by a driving motor and pressure rollers whose two ends are mounted on the moving trolley through rockers, and the number and position of the rollers can match the number and position of the synchronous winding stations on the winding device. The other end of the rocker arm is also fixedly connected to the movable end of the cylinder with a potential ruler fixedly arranged on the moving trolley, so that the cylinder drives the pressure roller to press the winding roller. The potential ruler is preset with a zero position on the cylinder. The potential ruler and the driving motor are communicated and linked, so that when the piston rod of the cylinder is not at the zero position, the driving motor drives the moving trolley to retreat until the piston rod of the cylinder returns to the zero position, so that the pressure roller can retreat smoothly in real time as the thickness of the coil on the winding roller it presses increases, so that the winding roller is always in a state of being pressed by substantially the same pressure during the winding process, thereby well ensuring that the tightness of each layer of the wound coil from front to back is comparable.

[0006] Preferably, the movable trolley includes a symmetrically arranged left wall panel and a right wall panel, which are connected by a cross beam. The left wall panel and the right wall panel are respectively slidably arranged on two parallel linear guide rails which are relatively fixed to the position of the winding device, and are respectively driven by two synchronous belts driven by the driving motor through a transmission shaft. Specifically, the left wall panel and the right wall panel are respectively fixedly connected to synchronous belt seats fixed on the two synchronous belts, so that they can move simultaneously along the linear guide rails under the drive of the driving motor.

[0007] Preferably, a precision linear displacement sensor is provided at the rear end of the mobile trolley to control and detect the initial position and final position of the mobile trolley.

[0008] Preferably, the linear guide rail and the precision linear displacement sensor are both fixedly mounted on the wall plate of the winding device.

[0015] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0016] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0017] like Figure 1-2 As shown, a pressure roller device for the winding mechanism of the slitting machine is used to be arranged next to the winding device to press the winding roller 20 during winding. The pressure roller device includes a moving trolley 1 driven by a driving motor 2 and pressure rollers 4 whose ends are mounted on the moving trolley 1 through rocker arms 3, and the number and position of the rollers can match the number and position of the synchronous winding stations on the winding device. The other end of the rocker arm 3 is also fixedly connected to the movable end of a cylinder 5 with a potential ruler fixedly arranged on the moving trolley 1, so that the cylinder 5 drives the pressure roller 4 to press against the winding roller 20. A zero position is preset on the potential ruler on the cylinder 5, and the potential ruler and the drive motor 2 are communicated and linked, so that when the piston rod of the cylinder 5 is not at the zero position, the drive motor 2 drives the moving trolley 1 to retreat until the piston rod of the cylinder 5 returns to the zero position, thereby allowing the pressure roller 4 to retreat smoothly in real time as the thickness of the coil on the winding roller 20 it presses increases, so that the winding roller 20 is always in a state of being pressed by substantially the same pressure during the winding process, thereby ensuring that the tightness of each layer of the wound coil from front to back is comparable.

[0018] The mobile trolley 1 includes a symmetrically arranged left wall panel 1.1 and a right wall panel 1.2, which are connected by a crossbeam 1.3. The left wall panel 1.1 and the right wall panel 1.2 are respectively slidably arranged on two parallel linear guide rails 6 which are relatively fixed to the position of the winding device, and are respectively driven by two synchronous belts 1.5 driven by the drive motor 2 through a transmission shaft 1.4. Specifically, the left wall panel 1.1 and the right wall panel 1.2 are respectively fixedly connected to synchronous belt seats 1.6 fixed on the two synchronous belts 1.5, so that they can move simultaneously along the linear guide rails 6 under the drive of the drive motor 2.

[0019] The rear end of the mobile vehicle 1 is also provided with a precision linear displacement sensor 7 for controlling and detecting the initial position and final position of the mobile vehicle 1 .

[0020] The linear guide rail 6 and the precision linear displacement sensor 7 are both fixedly arranged on the wall panel 21 of the winding device. One end of the precision linear displacement sensor 7 is mounted on the wall panel 21 of the winding device, and the other end is connected to the moving trolley 1, specifically, to the left wall panel 1.1 or the right wall panel 1.2.

[0021] The winding device comprises two synchronous winding stations arranged one above and one below, and two pressing rollers 4 are correspondingly arranged on the movable carriage.

[0022] Working principle:

[0023] When it is necessary to press the winding roller 20 for winding, the pressure roller 4 is moved to the position of pressing the winding roller 20 through the control of the drive motor 2 and the cylinder 5. At this time, the piston rod of the cylinder 5 is at the zero position preset by the potentiometer on the cylinder. As the thickness of the coil increases, the piston rod of the cylinder 5 will be pushed backward. When it leaves the zero position preset by the potentiometer on the cylinder, the drive motor 2 will drive the moving trolley 1 backward in real time through the linkage between the potentiometer and the drive motor 2 until the piston rod of the cylinder 5 returns to the zero position, and repeat the zero position recovery action until the winding is completed. While the drive motor 2 controls the translation of the moving trolley 1, the electrical signal generated by the precision linear displacement sensor 7 is used to display the precise moving distance to ensure the translation distance of the pressure roller 4. When the coil needs to be unloaded, the drive motor drives the moving trolley to move backward a certain distance and leave the winding roller.

[0024] The pressure roller device for the winding mechanism of the slitting machine of the utility model has an ingenious structure. Through the cooperation of the potentiometer arranged on the cylinder and the driving motor of the mobile trolley, the position of the piston rod of the cylinder can be adjusted to the zero position in real time, that is, the pressure roller can smoothly retreat as the thickness of the coil increases, thereby ensuring that the pressure of the pressure roller on the winding roller is always in a substantially same state, thereby ensuring the quality of the winding, and due to its adjustment sensitivity, it can also adapt to the winding of different coils or coils of different thicknesses, has strong practicality, and is worthy of promotion.

[0025] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
