[0026] An electric push rod 15 is fixedly installed at the middle position of the top of the movable frame 111 and on one side away from the coating box 6. The telescopic end of the electric push rod 15 is connected to a sealing plate 151, and the sealing plate 151 is installed to be lifted and lowered with the movable frame 111 through the electric push rod 15.

[0027] A feed pipe 62 is fixedly connected to the middle of the top of the coating box 6, and an overflow pipe 66 is fixedly connected to the middle of one side of the coating box 6 close to the coating roller 5, and the overflow pipe 66 is open on the side facing the coating roller 5, and the overflow pipe 66 is connected to the bottom shell body 67 through the coating box 6 and the telescopic shell 68. The liquid level sensor 14 penetrates the movable frame 111 and the coating box 6 and is inserted on the inner side of the bottom shell body 67. The liquid level sensor 14 is used to monitor the liquid level inside the bottom shell body 67.

[0028] The first blade cylinder 71 and the second blade cylinder 72 are clamped and installed on the inner side of the deformation frame 7, and the first blade cylinder 71 is horizontally installed with the frame 1 through the deformation frame 7, and the second blade cylinder 72 is obliquely installed with the first blade cylinder 71 through the deformation frame 7. A first rod 73 is telescopically installed on the first blade cylinder 71, and a second rod 74 is telescopically installed on the second blade cylinder 72. The middle parts of the adjacent ends of the first rod 73 and the second blade cylinder 72 are both threadedly connected with a ball head rod 78, and the adjacent ends of the first rod 73 and the second blade cylinder 72 are both installed with a torsion piece 77 through the ball head rod 78, and the torsion piece 77 is installed on the side of the first support plate 75 away from the square frame 11.

[0029] The PLC controller 10 is used to receive signals from the sensor 9 and the liquid level meter 14, and control the power module 13 to supply power to the first blade cylinder 71 and the second blade cylinder 72 according to a preset coating thickness threshold. The PLC controller 10 is used to receive signals from the liquid level meter 14, and control the power module 13 to supply power to the servo motor 12 according to a preset liquid level height threshold. The power module 13 is used to specifically supply power to the servo motor 12 to cooperate with the PLC controller 10 to accurately control the opening and closing states of the servo motor 12, to achieve precise control of the power-off and power-on time of the servo motor 12, and to achieve precise adjustment of the height of the liquid level inside the telescopic shell 68 by the worm 61; the PLC controller 10 is electrically connected to the drive motor 4, the control panel 8, the sensor 9, the servo motor 12, the power module 13, the liquid level meter 14, the electric push rod 15, the stepping motor 114, the first blade cylinder 71, and the second blade cylinder 72.

[0030] First, install the frame 1 at the designated position of the production workshop to ensure its stability; then install the transmission system, including the conveyor belt 2, the transmission roller 3, the transmission box and the drive motor 4. The conveyor belt 2 is installed on the transmission roller 3 and is driven by the drive motor 4 and the transmission box to achieve continuous transportation of paper; then install the coating system, install the coating roller 5 above the frame 1, and install the coating box 6 side by side in front of it, so that the opening of the overflow pipe 66 fits the surface of the coating roller 5, and the coating roller 5 is kept tangent to the opening of the overflow pipe 66 at all times. Add an appropriate amount of silicone oil to the U-shaped tube cavity structure in advance through the feed pipe 62, so that the liquid level of the silicone oil is lower than the opening of the overflow pipe 66 and is located below the overflow pipe 66.

[0031] Then install the control system, fix the control panel 8 on the side of the frame 1, and install the sensor 9 at the bottom of the frame 1 and near the coating roller 5 for real-time monitoring of the coating thickness; the PLC controller 10 is connected to the sensor 9, the servo motor 12, the power module 13, the liquid level meter 14 and the stepper motor 114 of the coating roller 5, and adjusts the rotation speed of the coating roller 5 according to the feedback signal to ensure precise control of the coating thickness.

[0032] After the equipment is started, the paper is transported to the bottom of the coating roller 5 by the conveyor belt 2. The PLC controller 10 starts the servo motor 12 to drive the turbine 121 to rotate counterclockwise according to the real-time feedback of the silicone oil level signal of the liquid level meter 14. The meshing transmission of the turbine 121 and the worm 61 is used to make the worm 61 rotate counterclockwise in the ball spline 112, driving the bottom shell 67 to rise, squeezing the internal space of the telescopic shell 68, and slowly raising the liquid level of the silicone oil in the telescopic shell 68 towards each other, so as to control the total amount of silicone oil overflowing from the overflow pipe 66. When the liquid level change meets the preset silicone oil overflow threshold, the servo motor 12 no longer rotates at this time, and the silicone oil overflowing from the overflow pipe 66 is evenly coated on the paper with the help of the coating roller 5 under the operation of activating the stepper motor 114 to drive the coating roller 5 to rotate and coat on the surface of the paper.

[0033] When silicone oil is coated on the paper by the coating roller 5, the thickness of the silicone oil at the coating part is monitored in real time by the sensor 9. Once it is detected that the thickness of the silicone oil does not meet the preset coating thickness threshold, the information will be fed back to the PLC controller 10 under the monitoring of the sensor 9, and the PLC controller 10 controls the first blade cylinder 71 and the second blade cylinder 72 to start, and the first blade cylinder 71 drives the first rod 73 to retract, and the second blade cylinder 72 drives the second rod 74 to extend, and drives the first support plate 75 to adjust 90 degrees counterclockwise around the top of the second support plate 76, and the square frame 11 is translated backward as a whole for a distance, and the above operation is repeated again to apply the silicone oil on the paper for a second time, so that the silicone oil thickness meets the preset coating thickness threshold. After the supplementary coating action is completed, the first blade cylinder 71 and the second blade cylinder 72 are immediately activated to perform a return operation, return to the initial coating operation position, and continue the coating operation.

[0034] On the other hand, when the coating roller 5 is coating the paper with silicone oil, the thickness of the silicone oil at the coating portion is monitored in real time via the sensor 9. Once the thickness of the silicone oil is detected to exceed the preset coating thickness threshold, the information is fed back to the PLC controller 10 under the monitoring of the sensor 9. The PLC controller 10 controls the first blade cylinder 71 and the second blade cylinder 72 to start, and the first blade cylinder 71 drives the first rod 73 to retract, and the second blade cylinder 72 drives the second rod 74 to extend, driving the first support plate 75 to adjust the angle in the counterclockwise direction around the top of the second support plate 76; the square frame 11 is translated backward as a whole to transform a distance; at this time, the servo motor 12 is activated, and the turbine 121 is engaged and rotated with the worm 61 to sink the bottom shell 67 downward. The principle of communicating vessels is used to make the silicone oil level lower than the opening of the overflow pipe 66, so that the silicone oil no longer overflows from the overflow pipe 66. At this time, since there is no replenished silicone oil on the surface of the coating roller 5, and the silicone oil on the surface of the coating roller 5 is coated on the paper at the initial coating operation station, the coating roller 5 can be used as a recovery structure for dipping silicone oil, and the silicone oil excessively coated on the paper can be returned to the coating roller 5, so that the thickness of the silicone oil layer on the paper meets the preset coating thickness threshold.

[0035] Among them, the first support plate 75 is driven to make an angle adjustment action in the counterclockwise direction around the top of the second support plate 76. Specifically: the distance between the coating roller 5 and the silicone oil layer on the surface of the paper can be controlled in real time according to the monitoring information of the sensor 9 and the feedback to the PLC controller 10, so that the use of the first blade cylinder 71 and the second blade cylinder 72 can be finely controlled by the PLC controller 10, the retraction amount of the first rod 73 can be controlled, and the extension amount of the second rod 74 can be controlled, so that the coating roller 5 is set and positioned at a height on the paper, and the excess silicone oil on its surface can be dipped and recovered, so that the silicone oil thickness meets the preset coating thickness threshold. After the silicone oil recovery action is completed, the first blade cylinder 71 and the second blade cylinder 72 are immediately enabled to perform a return operation, return to the initial coating operation position, and continue the coating operation.

[0036] During use, the real-time monitoring of the silicone oil liquid level inside the U-shaped tubular cavity structure by the liquid level meter 14 facilitates the PLC controller 10 to control the activation time of the servo motor 12, so as to achieve precise control of the silicone oil liquid level inside the telescopic shell 68 with the help of the worm 61 under the precise thread guidance and adjustment of the ball spline 112, and to achieve precise control of the silicone oil outflow at the opening of the overflow pipe 66, thereby ensuring the uniformity and uniformity of the silicone oil coating thickness on the paper by the silicone oil coating equipment.

[0037] Combined with the description of the above-mentioned use process, it can be known that the silicone oil coating equipment can be used with the cooperation between the deformation frame 7 and the structures thereon. After the liquid level device 14 fails to monitor the silicone oil coating thickness on the paper, or when the silicone oil coating thickness on the paper does not meet the preset coating thickness threshold due to other factors, it can automatically detect the abnormality and can timely move the coating roller 5 back a certain distance to re-coat or recycle the silicone oil on the paper, so as to secondary ensure the uniform thickness coating function of the silicone oil on the paper.

[0038] Among them, the sensor 9 can monitor the coating thickness in real time and make feedback adjustments through the PLC controller 10 to make the coating process more stable and accurate. The digital display function on the control panel 8 enables the operator to monitor the production parameters in real time and facilitate adjustment and control.

[0039] From the description of the above structural functions, it can be seen that the overall structure of the silicone oil coating equipment is simple and easy to operate. It can achieve uniform coating of silicone oil and uniform thickness coating of silicone oil, thereby improving production efficiency and product quality. In addition, the coating operation height of the coating roller 5 can be adjusted in linkage through the deformation frame 7 and its affiliated structure to adapt to the silicone oil coating operation of the coating roller 5 on paper of different thicknesses. It is also suitable for the production and processing of various types of silicone oil paper.

[0040] The second embodiment is based on the first embodiment.

The seat plate 772 is bolted on the first support plate 75, and a short pin 773 is inserted in the middle of the torsion member 77. A locking pin 774 is inserted on the curved surface of the torsion member 77. The short pin 773 is positioned and assembled with the torsion member 77 through the locking pin 774, and the ball head rod 78 is hinged to the short pin 773.

[0041] A folded corner 751 is fixedly installed on one side of one end of the first support plate 75 close to the second support plate 76, and an arc-shaped abutment plate 752 is fixedly connected to the other side of one end of the first support plate 75 close to the second support plate 76. The folded corner 751 and the arc-shaped abutment plate 752 are used to limit the rotational range of the first support plate 75 around the second support plate 76.

[0042] Through the installation method of the above structure, the torsion member 77 can rotate on the seat plate 772 around the clamping head 771, and the short pin 773 can be locked in the torsion member 77 by the locking pin 774. In addition, the first rod member 73 and the second rod member 74 are hinged with the ball head of the short pin 773 through the ball head rod 78. This can effectively cooperate with the telescopic changes of the first rod member 73 driven by the first blade cylinder 71 and the telescopic changes of the second rod member 74 driven by the second blade cylinder 72, and jointly accurately adjust the rotation accuracy of the first support plate 75, thereby realizing the adjustment of the installation height of the coating roller 5 on the frame 1.

[0043] When in use, by starting the first blade cylinder 71 and the second blade cylinder 72, the first blade cylinder 71 drives the first rod 73 to retract or extend, and the second blade cylinder 72 drives the second rod 74 to extend or retract, driving the first support plate 75 to make an angular adjustment in the counterclockwise or clockwise direction around the top of the second support plate 76, and the coating roller 5 can be freely adjusted in the height variation range of the overall highest point and the lowest point in the hinged state of the first support plate 75 and the second support plate 76. The installation height and the installation position of the coating roller 5 above the frame 1 can be freely adjusted. During the adjustment period, the coating roller 5 and the square frame 11 as a whole are always parallel to the conveyor belt 2, which will not affect the overflow of silicone oil at the opening of the overflow pipe 66, and can ensure that the overflow pipe 66 can normally overflow and coat the silicone oil onto the coating roller 5.

[0044] Not only can the vertical distance between the coating roller 5 and the paper be changed to apply silicone oil to papers of different thicknesses, but also the coating pressure of the coating roller 5 on the paper surface can be changed to ensure uniform coverage of the silicone oil on the paper surface. The silicone oil coating position of the coating roller 5 on the paper can be changed to achieve adaptive blanking of the silicone oil coating position on the paper to meet different processing requirements.

[0045] By adjusting the front and rear position of the coating roller 5 above the frame 1 with the help of the deformation frame 7, not only can the silicone oil layer that does not meet the standards be supplemented, but the silicone oil that is accidentally excessively coated on the paper can also be recovered on the coating roller 5 to avoid the waste of silicone oil. At the same time, after the coating roller 5 returns to the initial working position, the recovered silicone oil can be promptly coated on the paper that needs to be coated subsequently.

[0046] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
