Abstract
Description
Technical Field
[0001] This utility model relates to the field of sheet processing technology, specifically to a multi-layer sheet synchronous correction mechanism. Background Technology
[0002] Sheet materials refer to long, continuous materials such as paper, film, metal foil, rubber, and non-woven fabrics. In the processing of sheet materials, which involves transmission through long production lines and being stretched by multiple tensioners, coating rollers, and guide rollers, the roll material will inevitably experience some degree of deviation. To ensure that the edges of the roll material are aligned after winding, a correction and centering process is required before winding. Otherwise, the roll material on the winding roller will be messy, affecting the winding and the appearance quality of the roll material. Therefore, a multi-layer sheet material synchronous correction mechanism is needed.
[0003] Regarding the aforementioned related technologies, the applicant believes that a multi-layer sheet synchronous correction mechanism, when in operation, involves placing multiple layers of sheets on a device, conveying the sheets via transfer rollers, and detecting the sheets using correction sensors. When the sheet deviates, a control cylinder is activated. This cylinder can push the slider forward or pull it back, causing the guide rollers to move. The sheet, guided by the deflection of the guide rollers, rotates at a small angle, thus correcting the sheet's deviation. However, when the sheet is conveyed over long distances in a production line, the stretching action of multiple tensioning devices, coating rollers, and guide rollers can cause stretching and wrinkling on the sheet surface, leading to slippage during the correction process and affecting the correction accuracy. This phenomenon is particularly common when processing flexible materials such as films and paper. Utility Model Content
[0004] The purpose of this invention is to provide a multi-layer sheet synchronous correction mechanism to solve the problem mentioned in the background art that the sheet surface will be stretched and wrinkled during the conveying of the sheet, causing the sheet to slide during correction, thereby affecting the correction accuracy of the device.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer sheet synchronous correction mechanism, comprising a base and an adjustment mechanism. The adjustment mechanism is disposed at the top of the base and includes a support column disposed at the top of the base. A drive motor is disposed at the top of the support column, and a lead screw is disposed at the output end of the drive motor. A threaded seat is engaged with the outside of the lead screw.

An elastic pressure roller is rotatably disposed inside the movable seat. A support roller is rotatably disposed inside the support column and is disposed directly below the elastic pressure roller.
[0006] By adopting the above technical solution, the operation of the drive motor can drive the lead screw to rotate, causing the threaded seat outside the lead screw to move up and down, which can drive the movable seat to move, adjust the distance between the elastic pressure roller and the support roller, press and smooth the sheet, and minimize the slippage of the sheet during correction, thereby improving the correction accuracy of the device.
[0007] Preferably, both ends of the movable seat are provided with movable blocks, and the inner side of the support column is provided with a limiting groove that matches the movable blocks.

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1
[0028] Please see Figures 1 to 4 This embodiment provides a technical solution: a multi-layer sheet synchronous correction mechanism, including a base 2 and an adjustment mechanism 1. The adjustment mechanism 1 is located at the top of the base 2 and includes a support column 101 at the top of the base 2. A drive motor 103 is fixedly connected to the top of the support column 101. The drive motor 103 operates based on the principle of electromagnetic induction. When three-phase AC power is applied to the stator winding, a rotating magnetic field is generated in the stator core. Its rotational speed is determined by the power supply frequency and the number of pole pairs of the motor. The rotor conductor cuts the magnetic lines of force in the rotating magnetic field to generate an induced current. The current interacts with the magnetic field to generate electromagnetic torque, driving the rotor to rotate. When selecting the appropriate model, it should be selected according to the actual needs. All the components required in the drive motor 103 are existing technologies and will not be described in detail below.
[0029] A lead screw 107 is fixedly connected to the output end of a drive motor 103. A threaded seat 106 is engaged with the outside of the lead screw 107. A connecting rod 105 is fixedly connected to one end of the threaded seat 106 near the center point inside the base 2. A movable seat 104 is fixedly connected to the bottom end of the connecting rod 105. An elastic pressure roller 109 is rotatably disposed inside the movable seat 104. A support roller 102 is rotatably disposed inside the support column 101. The support roller 102 is disposed directly below the elastic pressure roller 109. The movable seat 104 is moved up and down by the forward and reverse rotation of the drive motor 103, which can adjust the distance between the elastic pressure roller 109 and the support roller 102 to ensure that the distance matches the total thickness of the multilayer sheet and that the elastic pressure roller 109 applies uniform pressure to the sheet. It can effectively smooth out wrinkles on the surface of the sheet caused by uneven tension, and reduce the relative sliding amount between the sheet and the roller during the correction process. The support roller 102 is provided in two sets, which can facilitate synchronous correction of the two sets of sheets. The movable block 108 is fixedly connected to both ends of the movable seat 104, and the inner side of the support column 101 is provided with a limiting groove that matches the movable block 108.
[0030] The overall effect of this embodiment is as follows: The drive motor 103 is activated by a control switch, causing the vertically arranged ball screw 107 to rotate. The threaded seat 106, externally fitted to the screw 107, moves up and down along the axial direction of the screw 107 under the threaded transmission of the screw 107; this synchronously drives the two sets of movable seats 104 to move stably. An elastic pressure roller 109 is fixed to the bottom of the movable seat 104, with a support roller 102 positioned directly below it. By controlling the up and down movement of the movable seat 104 through the forward and reverse rotation of the drive motor 103, the distance between the elastic pressure roller 109 and the support roller 102 can be adjusted, ensuring that the distance matches the total thickness of the multi-layer sheet, and that the elastic pressure roller 109 applies uniform pressure to the sheet. This effectively smooths wrinkles on the sheet surface caused by uneven tension, reducing the relative sliding amount between the sheet and the roller during the correction process; combined with the buffering characteristics of the elastic pressure roller 109, it avoids damaging the ultra-thin sheet, ultimately improving the synchronous correction accuracy of the multi-layer sheet.
[0031] Example 2
[0032] Based on the above embodiment, the fixing frame 4 is fixedly connected to the top of the base 2, the support plate 3 is fixedly connected to the inner side of the fixing frame 4, the slide block 6 is fixedly connected to both ends of the top of the support plate 3, the slider 7 is slidably disposed inside the slide block 6, the correction roller 10 is rotatably disposed inside the slider 7, and the alignment sensor 5 is fixedly connected to the inner side of the fixing frame 4. The alignment sensor 5 is a laser displacement sensor adapted to the synchronous correction requirements of multi-layer sheets. Its core function is to collect the edge position offset of the sheet in real time. During operation, the alignment sensor 5 outputs a high-frequency laser beam through the transmitting end. The laser beam is vertically irradiated to the edge area of the sheet. The reflected light is focused by the optical lens of the receiving end, and the internal photoelectric conversion module converts the light signal into an electrical signal. Then, the signal processing unit calculates the deviation value between the edge of the sheet and the preset baseline. When the sheet is offset, the alignment sensor 5 immediately transmits the deviation data to the synchronous controller through the shielded cable. The controller compares the deviation threshold and triggers the correction command, providing data basis for the subsequent adjustment of the correction roller 10 driven by the micro cylinder 9. At the same time, the sensor has an edge defect recognition auxiliary function to ensure the reliability of the detection data. When selecting the appropriate model, the correct model should be selected according to the actual needs. All the components required in the above alignment sensor 5 are existing technologies and will not be described in detail below.
[0033] The accessory seat 8 is fixedly connected to one end of the slide 6, and the cylinder 9 is fixedly connected to one end of the accessory seat 8. The working principle of the cylinder 9 is to convert the pressure energy of compressed air into mechanical energy, driving the mechanism to achieve linear reciprocating motion, oscillation, and rotational motion. The cylinder 9 mainly consists of a cylinder barrel, end cover, piston, piston rod, and seals. Its basic working principle is to move the piston by compressing air, and to change the direction of piston rod movement by changing the air intake direction. When selecting a cylinder 9, the appropriate model should be selected according to actual needs. All the components required in the cylinder 9 mentioned above are existing technologies and will not be described in detail below. The output end of the cylinder 9 is connected to the slide 7 by fixing bolts.
[0034] The effect achieved by the entire second embodiment is as follows: the sheet is detected by the alignment sensor 5. When the sheet is deviated, the control cylinder 9 is activated. At this time, the cylinder 9 can push the slider 7 forward or pull it back, so that the correction roller 10 moves. The sheet is guided by the deflection of the correction roller 10 and rotates at a small angle to achieve the correction of the sheet.
[0035] Working principle: The drive motor 103 is started by a control switch, which drives the vertically arranged ball screw 107 to rotate. The threaded seat 106 on the outside of the screw 107 moves up and down along the axial direction of the screw 107 under the action of the screw 107 thread transmission; it can synchronously drive the two sets of movable seats 104 to move stably. The bottom of the movable seat 104 is fixed with an elastic pressure roller 109, and a support roller 102 is set directly below it; by controlling the up and down movement of the movable seat 104 by the forward and reverse rotation of the drive motor 103, the distance between the elastic pressure roller 109 and the support roller 102 can be adjusted to ensure that the distance matches the total thickness of the multi-layer sheet, and that the elastic pressure roller 109 forms a uniform pressure on the sheet. It can effectively smooth out the wrinkles on the surface of the sheet caused by uneven tension, reduce the relative sliding amount between the sheet and the roller during the correction process; combined with the buffering characteristics of the elastic pressure roller 109, it can avoid crushing the ultra-thin sheet, and ultimately improve the synchronous correction accuracy of the multi-layer sheet.
[0036] Secondly, the smoothed sheet is fed onto the alignment roller 10. The alignment sensor 5 detects the sheet. When the sheet deviates, the control cylinder 9 is activated. At this time, the cylinder 9 can push the slider 7 forward or pull it back, causing the alignment roller 10 to move. The sheet is guided by the deflection of the alignment roller 10 and rotates at a small angle to achieve the alignment of the sheet.
