[0026] like Figures 1 to 4 The U-shaped fixing frame is a kind of thick paper binding device shown in FIG1 , and comprises a U-shaped fixing frame, an inner side wall of the U-shaped fixing frame 1 is installed with a support plate 2, thick paper is placed on the upper surface of the support plate 2, and an opening mechanism 3 for opening holes in the thick paper is installed on the top of the inner wall of the U-shaped fixing frame 1, two groups of card slots are opened on the upper surface of the support plate 2, and a positioning mechanism 4 is arranged inside the two groups of card slots of the support plate 2, a groove is opened on the back side of the U-shaped fixing frame 1, and a cleaning mechanism 7 is installed inside the groove of the U-shaped fixing frame 1; specifically, the opening mechanism 3 is started and pushed into the interior of the thick paper, so that the opening mechanism 3 cuts and opens holes in the thick paper during the continuous downward pressure, and then the lower surface of the opening mechanism 3 abuts against the upper surface of the thick paper, so that the subsequent thick paper is not easily deformed and damaged during the opening process, thereby reducing the damage rate of the subsequent thick paper during the binding process, thereby improving the applicability of the device.

[0027] like Figures 1 to 3As shown, the hole opening mechanism 3 includes a hydraulic cylinder 301, which is installed on the top of the inner wall of the U-shaped fixing frame 1, and a fixed plate 302 is installed at the output end of the hydraulic cylinder 301. The lower surface of the fixed plate 302 is provided with multiple groups of cutting dies 303, and the outer surfaces of the multiple groups of cutting dies 303 are slidably connected with positioning plates 304. Two groups of damping springs 305 are installed on the upper surface of the positioning plate 304. The top ends of the two groups of damping springs 305 are installed on the lower surfaces of the two groups of fixing plates 302. The inner walls of the multiple groups of cutting dies 303 are all provided with electric telescopic rods 306. The output ends of the multiple groups of electric telescopic rods 306 are all installed with fixed blocks 307. The multiple groups of fixed blocks 307 are respectively slidably connected to the interiors of the multiple groups of cutting dies 303.

[0028] Specifically, when thick paper sheets are neatly stacked and placed on the upper surface of the support plate 2, the hydraulic cylinder 301 is activated to push the fixing plate 302, driving the back surfaces of the multiple sets of cutting dies 303 and the positioning plate 304 to abut against the upper surface of the thick paper sheets, so that the subsequent multiple sets of cutting dies 303 cut holes inside the thick paper sheets during the continuous downward pressure, and then the positioning plate 304 is squeezed by the two sets of damping springs 305 and continuously abuts against the upper surface of the thick paper sheets, so that the subsequent thick paper sheets are less likely to be deformed and damaged during the hole opening process, thereby reducing the damage rate of the subsequent thick paper sheets during the binding process, thereby improving the applicability of the device;

[0029] At the same time, when the subsequent staff resets the position of the three sets of cutting dies 303 by starting the hydraulic cylinder 301, the fixed block 307 is pushed to move by starting the electric telescopic rod 306, and then the position of the fixed block 307 is set inside the cutting die 303, so that the subsequent fixed block 307 can push out the paper scraps accumulated inside the cutting die 303 during the downward movement, thereby minimizing the impact of the paper scraps accumulated inside the subsequent cutting die 303 on the normal opening of thick paper by the cutting die 303.

[0030] like Figure 1 、 Figure 2 and Figure 4As shown, the positioning mechanism 4 includes a university-type positioning plate 401 and an electric telescopic rod 2 402. The electric telescopic rod 2 402 is installed on the lower surface of the support plate 2. The university-type positioning plate 401 is slidably connected to the two groups of card slots of the support plate 2. The output end of the electric telescopic rod 2 402 is installed with a connecting rod 403. The left and right sides of the connecting rod 403 are respectively installed on the left and right inner walls of the university-type positioning plate 401; specifically, when subsequent thick paper stacks are placed on the upper surface of the support plate 2, the electric telescopic rod 2 402 is started to push the connecting rod 403 to pull the university-type positioning plate 401 to move, so that the top of the inner wall of the university-type positioning plate 401 is abutted against the upper surface of the thick paper at the upper end of the support plate 2, so that the subsequent positioning mechanism 4 limits the moving position of the thick paper during the hole opening and binding process, thereby avoiding the subsequent thick paper from moving during the hole opening process and causing the internal hole of the thick paper to shift, thereby improving the stability of the subsequent device in the process of hole opening for thick paper.

[0031] like Figure 2 As shown, the cleaning mechanism 7 includes a cleaning scraper 703 and an L-shaped fixing rod 701. The L-shaped fixing rod 701 is mounted on the back of the U-shaped fixing frame 1. The cleaning scraper 703 is slidably connected to the inside of the groove of the U-shaped fixing frame 1. A through hole is opened on the back of the L-shaped fixing rod 701. A fixing rod 702 is slidably connected inside the through hole of the L-shaped fixing rod 701. The fixing rod 702 is mounted on the back of the cleaning scraper 703. The lower surface of the cleaning scraper 703 is parallel to the upper surface of the support plate 2. The left and right sides of the cleaning scraper 703 are parallel to the left and right inner walls of the university-shaped positioning plate 401.

[0032] Specifically, after the subsequent multiple groups of fixed blocks 307 push the paper scraps out of the multiple groups of cutting dies 303, the cleaning scraper 703 is driven to move by pushing the fixed rod 702, and then the lower surface of the cleaning scraper 703 is kept parallel to the upper surface of the support plate 2, so that the subsequent fixed rod 702 pushes the paper scraps accumulated on the upper surface of the support plate 2 during the movement to move the paper scraps out of the upper surface of the support plate 2, thereby minimizing the subsequent accumulation of paper scraps on the upper end of the support plate 2 and affecting the opening mechanism 3 to open holes for thick paper, resulting in the inability to effectively bind subsequent thick paper; the fixed rod 702 is slidably connected to the through hole of the L-shaped fixed rod 701, so that the internal through hole of the L-shaped fixed rod 701 restricts the moving path of the fixed rod 702 and the cleaning scraper 703, thereby minimizing the subsequent deviation of the cleaning mechanism 7 during use, resulting in the cleaning mechanism 7 being unable to clean the paper scraps accumulated on the surface of the support plate 2.

[0033] like Figure 1 and Figure 2As shown, two groups of side panels 6 are installed on the upper surface of the support plate 2, and the back sides of the two groups of side panels 6 are in contact with the inner side wall of the U-shaped fixing frame 1, and the front sides of the two groups of side panels 6 are in contact with the back side of the university-type positioning plate 401. The adjacent sides of the two groups of side panels 6 are parallel to the left and right inner walls of the university-type positioning plate 401; specifically, the positions of the two groups of side panels 6 are set on the left and right sides of the upper end of the support plate 2, and then the positions of the two groups of side panels 6 are located between the university-type positioning plate 401 and the inner side wall of the U-shaped fixing frame 1, so that the subsequent two groups of side panels 6 and the university-type positioning plate 401 limit the movement path of paper scraps at the upper end of the support plate 2, thereby avoiding as much as possible the subsequent indoor air blowing and the floating of paper scraps accumulated at the upper end of the support plate 2.

[0034] like Figure 1 and Figure 2 As shown, a storage box 5 is placed at the bottom of the inner wall of the U-shaped fixing frame 1, and the storage box 5 is located at the lower end of the moving path of the cleaning scraper 703; specifically, by the storage box 5 being located at the lower end of the moving path of the cleaning scraper 703, the subsequent storage box 5 can collect the paper scraps pushed and cleaned by the cleaning scraper 703, thereby improving the hygiene of the subsequent use of the device; by placing the storage box 5 at the bottom of the inner wall of the U-shaped fixing frame 1, the subsequent storage box 5 can be transported and moved, thereby facilitating the subsequent staff to clean and replace the storage box 5.

[0035] In summary: by starting the hydraulic cylinder 301 to push the fixed plate 302, multiple sets of cutting dies 303 and the back of the positioning plate 304 are driven to abut against the upper surface of the thick paper, so that the subsequent multiple sets of cutting dies 303 cut and open holes in the thick paper during the continuous downward pressure, and then the positioning plate 304 is squeezed by the two sets of damping springs 305 and continuously abuts against the upper surface of the thick paper, so that the subsequent thick paper is not easily deformed or damaged during the hole opening process, thereby reducing the damage rate of the subsequent thick paper during the binding process; by starting the electric telescopic rod 306 to push the fixed block 307 to move, and then the position of the fixed block 307 is set inside the cutting die 303, the subsequent fixed block 307 is pushed out during the downward movement of the cutting die 303, thereby minimizing the impact of the paper scraps accumulated inside the subsequent cutting die 303 on the normal hole opening of the thick paper by the cutting die 303.

[0036] At the same time, by starting the electric telescopic rod 2 402, the connecting rod 403 is pushed to pull the university-type positioning plate 401 to move, and the top of the inner wall of the university-type positioning plate 401 is abutted against the upper surface of the thick paper at the upper end of the support plate 2, so that the subsequent positioning mechanism 4 limits the moving position of the thick paper during the hole opening and binding process, thereby trying to avoid the subsequent thick paper from moving during the hole opening process and causing the internal hole of the thick paper to be offset; by pushing the fixed rod 702 to drive the cleaning scraper 703 to move, and then by keeping the lower surface of the cleaning scraper 703 and the upper surface of the support plate 2 parallel, the subsequent fixed rod 702 pushes the paper scraps accumulated on the upper surface of the support plate 2 to move and remove the paper scraps out of the upper surface of the support plate 2, thereby trying to avoid the subsequent accumulation of paper scraps on the upper end of the support plate 2 affecting the hole opening mechanism 3 to open the thick paper, resulting in the inability to effectively bind the subsequent thick paper.
