The lower part of the extrusion piece 34 is in extrusion cooperation with the right part of the first wedge block 31. The downward movement of the placing plate 21 drives the wedge piece to move downward. The downward movement of the wedge piece drives the extrusion piece 34 to move upward through the first wedge block 31. In turn, the limiting frame 35 moves inward to limit the paper.

[0036] When people need to squeeze the paper dry, the paper can be stacked on the upper part of the placing plate 21, and then the placing plate 21 is moved downward, the first pressure spring 25 is compressed, the placing plate 21 moves downward to drive the rack and wedge to move downward, the rack moves downward to drive the rotating shaft to rotate through the gear 22, the rotating shaft rotates to drive the screw rod 23 to rotate through the bevel gear 22, the screw rod 23 rotates to drive the first pressing plate 24 to move downward, the first pressing plate 24 moves downward faster than the placing plate 21, so the first pressing plate 24 moves downward to press the paper dry, so the water in the paper is squeezed out, when the wedge moves downward and contacts the first wedge block 31, the first wedge block 31 and the first guide rod 32 are driven to move rightward, the tension spring 33 is stretched, the first wedge block 31 moves rightward to press the extrusion piece 34 upward, the extrusion piece 34 moves upward to press the right limiting frame 35 leftward, the elastic piece is compressed, the right limiting frame 35 moves leftward to drive the left limiting frame 35 to move rightward through the bidirectional threaded rod 36, in this way, the two limiting frames 35 respectively move inward to automatically limit the left and right sides of the paper, so that the paper is pressed dry while avoiding displacement, after the paper is pressed dry, the placing plate 21 is loosened, under the action of the first pressure spring 25, the placing plate 21 moves upward to reset, the placing plate 21 moves upward to reset to drive the rack and wedge to move upward, the rack moves upward to drive the rotating shaft to reverse through the gear 22, the rotating shaft reverses to drive the screw rod 23 to reverse through the bevel gear 22, so that the first pressing plate 24 also automatically moves upward to reset, the wedge moves upward to release the first wedge block 31, under the action of the tension spring 33, the first wedge block 31 and the first guide rod 32 move leftward to reset, the extrusion piece 34 moves downward to reset due to its own weight, under the action of the elastic piece, the right limiting frame 35 moves rightward to reset, the left limiting frame 35 moves leftward to reset through the bidirectional threaded rod 36 to release the paper. Embodiment 2

[0037] On the basis of embodiment 1, as shown in Figure 1 , Figure 6 and Figure 7 , it further includes a scraping mechanism 4 for scraping water droplets on the front and back of the paper, the scraping mechanism 4 includes a second guide rod 41, a second pressure spring 42, a second pressing plate 43 and a drainage plate 44, the second guide rod 41 is connected on the top of the guide frame 11, the second pressing plate 43 is slidably connected on the second guide rod 41, the second pressure spring 42 is connected between the bottom of the second pressing plate 43 and the guide frame 11, the second pressure spring 42 is arranged around the second guide rod 41, the drainage plate 44 connected with the first pressing plate 24 is connected on the front and back of the second pressing plate 43, the drainage plate 44 is moved downward to scrape the water droplets on the front and back of the paper.

[0038] When the first pressing plate 24 moves downward to press the paper, the drainage plate 44 and the second pressing plate 43 are also moved downward, and the second pressure spring 42 is compressed. At this time, the water in the paper is squeezed out through the side of the paper. Then, the second pressing plate 43 can be continuously moved downward, which drives the drainage plate 44 to move downward. The drainage plate 44 moves downward to scrape the water droplets on the front and back sides of the paper downward, and the water is discharged. In this way, the paper can be squeezed faster, and the water can be squeezed out. After the water is squeezed out, the first pressing plate 24 moves upward to drive the second pressing plate 43 and the drainage plate 44 to move upward. Under the action of the second pressure spring 42, the second pressing plate 43 and the drainage plate 44 can be driven to move upward and reset.

[0039] As shown in Figure 1 , Figure 8 and Figure 9 , the device further comprises a shaking mechanism 5 for shaking the paper on the placing plate 21 to shake off the water. The shaking mechanism 5 comprises a fixed plate 51, a third guide rod 52, a third pressure spring 53, and a concave-convex plate 54. The left and right sides of the front upper part of the paper squeezing frame 1 are connected with the fixed plate 51. The lower part of the fixed plate 51 is slidingly connected with the third guide rod 52. The rear part of the third guide rod 52 is connected with the concave-convex plate 54 which is in pressing cooperation with the front part of the placing plate 21. The front part of the concave-convex plate 54 and the fixed plate 51 are connected with the third pressure spring 53. The placing plate 21 intermittently presses the concave-convex plate 54 to make the concave-convex plate 54 continuously move forward and backward to shake the placing plate 21.

[0040] When the placing plate 21 moves downward or upward, the placing plate 21 intermittently presses the concave-convex plate 54. When the placing plate 21 and the concave-convex plate 54 are in contact, the concave-convex plate 54 drives the third guide rod 52 to move forward, and the third pressure spring 53 is compressed. When the placing plate 21 and the concave-convex plate 54 are separated, the concave-convex plate 54 and the third guide rod 52 are driven to move backward and reset under the action of the third pressure spring 53. Through the above operation, the concave-convex plate 54 continuously moves forward and backward to shake and pat the placing plate 21. The water squeezed out shakes together with the placing plate 21, which facilitates the water to be discharged faster to press the paper.

[0041] As shown in Figure 1 , Figure 10 , Figure 11 and Figure 12As shown, the drying mechanism 6 for drying the paper is also included, and the drying mechanism 6 includes a second wedge block 61, a guide plate 62, a fourth guide rod 63, a fourth pressure spring 64 and a heating tube 65. The heating tube 65 is connected to the bottom of the placing plate 21. The guide plate 62 is connected to the front side of the bottom of the placing plate 21. The fourth guide rod 63 is slidably connected to the front side of the guide plate 62. The second wedge block 61 is connected between the right parts of the fourth guide rod 63 and is in extrusion fit with the first pressing plate 24. The guide plate 62 is connected to the right part of the second wedge block 61 and is in extrusion fit with a switch. The switch and the heating tube 65 are electrically connected. The first pressing plate 24 is in contact with the second wedge block 61 when moving downward, and drives the second wedge block 61 to move left to press the switch, and the heating tube 65 is turned on. The fourth pressure spring 64 is connected between the second wedge block 61 and the guide plate 62 and is wound on the fourth guide rod 63.

[0042] When the first pressing plate 24 is moved downward to contact the second wedge block 61, the second wedge block 61 is driven to move left to press the switch, the fourth pressure spring 64 is compressed, and the heating tube 65 is turned on. The heating tube 65 can dry the paper through the placing plate 21, so as to accelerate the drying of the paper. When the first pressing plate 24 is moved upward to release the second wedge block 61, the second wedge block 61 is driven to move right to reset and release the switch under the action of the fourth pressure spring 64, so that the heating tube 65 is automatically turned off.

[0043] As shown in Figure 1 and Figure 13 The edge cutting mechanism 7 for cutting the left and right sides of the paper is also included, and the edge cutting mechanism 7 includes a third pressing plate 71, a cutter holder 72 and a fifth pressure spring 73. The third pressing plate 71 is connected to the left and right sides of the first pressing plate 24. The cutter holder 72 is slidably connected to the third pressing plate 71. The cutter holder 72 is used for cutting the left and right sides of the paper. The fifth pressure spring 73 is connected between the cutter holder 72 and the third pressing plate 71.

[0044] After the paper is pressed dry, the cutter holder 72 can be moved downward to facilitate cutting the left and right sides of the paper. The fifth pressure spring 73 is stretched, so that the left and right sides of the paper are more flat. Then, the cutter holder 72 is released, and the cutter holder 72 is driven to move upward to reset under the action of the fifth pressure spring 73.
