[0036] To describe the technical content, achieved purpose and effects of the present utility model in detail, the following is described in conjunction with the implementation mode and with reference to the drawings.

[0037] Please refer to Figures 1 to 6 , a sizing device for sizing the surface of paper in paper processing, comprising:

[0038] A conveyor 1, with baffles 11 provided on both sides of the conveyor 1;

[0039] A coating device 2, which is arranged on one side of the baffle 11 close to the starting end of the conveyor 1. The coating device 2 includes a coating box 21, a connecting plate 22 and a scraper 23. An opening 211 is provided at the upper part of the coating box 21. The coating box 21 is detachably connected to the baffle 11. A plurality of glue discharge pipes 24 communicating with the inside of the coating box 21 are provided at the bottom of the coating box 21. A nozzle 241 is provided at the lower end of the glue discharge pipe 24. The connecting plate 22 is connected to the X-direction side of the coating box 21. The connecting plate 22 is located above the conveyor 1. The upper end of the scraper 23 is detachably connected to the X-direction side of the connecting plate 22 through a fastener 3. The scraper 23 is inclined;

[0040] A cleaning plate 4, on which a cleaning part 41 matching the lower end of the scraper 23 is provided. When the cleaning plate 4 moves in the Y direction, the cleaning part 41 is in frictional cooperation with the lower end of the scraper 23 to scrape off the colloid;

[0041] A driving member 5, which is connected to the baffle 11 and is used to drive the cleaning plate 4 to move;

[0042] A collection box 6, which is connected to the Y-direction side of the baffle 11.

[0043] In the above embodiments, the solution to be sized is placed in the sizing tank 21, and then the paper is placed at the starting end of the conveyor 1. The starting end of the conveyor 1 transports the paper to the lower part of the nozzle 241. The nozzle 241 applies glue to the paper. After the glue application, the paper is smeared by the squeegee 23, so that the glue can be evenly dispersed on the paper. Since a small amount of glue remains at the lower end of the squeegee 23 every time the squeegee 23 smears the paper, after the squeegee 23 is used for a period of time, a large amount of glue remains at the lower end of the squeegee 23. At this time, when the conveyor 1 transports the paper, the paper cannot be transported between the lower end of the squeegee 23 and the conveyor 1, which affects the smearing of the paper by the squeegee 23. At this time, the driving member 5 drives the cleaning plate 4 to move along the Y direction, and the cleaning plate 4 scrapes off a large amount of glue at the lower end of the squeegee 23, and finally scrapes the glue into the collection box 6 for unified collection and finally cleaning, thereby ensuring the stability of the subsequent smearing of the paper by the squeegee 23 and the smooth transportation of the paper. Compared with the prior art, it can clean a large amount of glue accumulated at the lower end after the squeegee 23 smears the paper evenly, thereby ensuring the efficiency of paper sizing.

[0044] As an alternative embodiment, the driving member 5 is a hydraulic cylinder or an electric push cylinder.

[0045] As an alternative embodiment, a connecting block 7 is provided on one side of the baffle 11 close to the starting end of the conveyor 1. A groove 71 is provided on the connecting block 7. Circular through holes 711 are provided on the inner walls of the groove 71 in the X direction and the -X direction. One end of a spring 712 is connected to the bottom of the circular through hole 711, and the other end of the spring 712 is connected to a plug block 713. A first slope 7131 is provided at the end of the plug block 713 away from the spring 712. A limiting post 714 is connected to the end of the plug block 713 close to the spring 712. The limiting post 714 is coaxially sleeved on the spring 712, and one end of the limiting post 714 extends outside the through hole. A limiting block 715 matching the groove 71 is provided at the lower part of the sizing tank 21. A second slope 7151 matching the first slope 7131 is provided at the lower part of the limiting block 715. A limiting groove 7152 matching the plug block 713 is provided on the side wall of the limiting block 715.

[0046] In the above embodiments, the limiting block 715 of the sizing tank 21 is aligned with the groove 71 and inserted downward. When the second slope 7151 of the limiting block 715 contacts the first slope 7131, the spring 712 is compressed. Continuing to insert downward, the spring 712 rebounds, so that the plug block 713 is inserted into the limiting groove 7152, fixing the sizing tank 21 to one side of the baffle 11 close to the starting end of the conveyor 1. When the sizing tank 21 needs to be disassembled, the limiting post 714 is pulled outwards, the plug block 713 squeezes the spring 712, and the spring 712 is compressed, so that the plug block 713 disengages from the limiting groove 7152, and the sizing tank 21 is disassembled.

[0047] As an alternative embodiment, the paper surface sizing device for paper processing further includes a feeding device 8, which is located on the reverse side of the X direction at the starting end of the conveyor 1. The feeding device 8 includes a base 81, a support plate 82, a cross plate 83, a screw rod guide rail assembly 84, a slider, a cylinder 85 and a suction cup 86. Support plates 82 are provided on both sides of the base 81. The cross plate 83 is connected above the support plates 82. The screw rod guide rail assembly 84 is connected to the cross plate 83. The axial direction of the screw rod guide rail assembly 84 is the X direction. The slider is slidably connected to the screw rod guide rail assembly 84. The cylinder 85 is connected to the lower part of the slider. The axial direction of the cylinder 85 is the vertical direction. The suction cup 86 is connected to the piston rod of the cylinder 85;

[0048] The screw rod guide rail assembly 84 drives the slider to switch between the first state and the second state;

[0049] In the first state, the suction cup 86 is located above the base 81;

[0050] In the second state, the suction cup 86 is located above the starting end of the conveyor 1.

[0051] In the above embodiment, the paper is placed on the base 81. The screw rod guide rail assembly 84 drives the slider to move to the first state. The cylinder 85 extends, and the paper is sucked by the suction cup 86. Then the screw rod guide rail assembly 84 drives the slider to move to the second state. The cylinder 85 extends, and the suction cup 86 releases the paper, enabling the paper to fall into the starting end of the conveyor 1. Through the automatic feeding of the paper, the efficiency of paper sizing is improved.

[0052] As an alternative embodiment, a liquid storage tank 9 is provided above the cross plate 83. The liquid storage tank contains sizing solution. A discharge pipe 91 is provided at the lower part of the liquid storage tank. One end of the discharge pipe 91 is located above the opening 211 of the coating tank 21. A valve 911 is provided on the discharge pipe 91.

[0053] In the above embodiment, by opening the valve 911, the sizing solution in the liquid storage tank 9 is put into the coating tank 21.

[0054] As an alternative embodiment, a threaded hole is provided on one side of the connecting plate 22 in the X direction. A through hole matching the threaded hole is provided at the upper end of the scraping plate 23. The fastener 3 is a screw.

[0055] In the above embodiment, the screw passes through the through hole and the threaded hole in sequence to connect the scraping plate 23 and the connecting plate 22.
