Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1-4 shown, the present utility model provides two technical solutions:

[0027] The first embodiment: A paper tray edge trimming device, comprising:

[0028] Frame 1, on one side of the upper surface of frame 1, two linear guide rails 11 are fixed. On the upper surface of linear guide rail 11, a placement plate 12 is provided. On one side of the middle part of the upper surface of placement plate 12, a fixed frame 13 is fixed. Fixed frame 13 is set as an inverted L-shaped structure. On the other side of the upper surface of placement plate 12, a cutting groove 14 is opened to facilitate the edge trimming work;

[0029] The limiting component 2 is arranged on the fixing frame 13 and cooperates with the placing plate 12 to press and limit the paper tray. The limiting component 2 includes a first air cylinder 21 fixed at one end of the upper surface of the fixing frame 13. The output end of the first air cylinder 21 is connected with a pressing plate 22. The first air cylinder 21 drives the pressing plate 22 to move downward to facilitate pressing and limiting the paper tray. In the middle of one end of the upper surface of the pressing plate 22, a piston cylinder 23 is fixed. The top of the piston cylinder 23 is fixed with a second air cylinder 24. A rubber pad 25 is adhered to the lower surface of the pressing plate 22. The rubber pad 25 plays a role in damping and limiting, and at the same time avoids damaging the paper tray. In the middle of one side of the rubber pad 25, a plurality of ventilation grooves 26 distributed in a rectangular array are formed. The ventilation grooves 26 are communicated with the piston cylinder 23. The output end of the second air cylinder 24 is connected with the piston in the piston cylinder 23. When the second air cylinder 24 drives the piston to move upward, negative pressure is generated in the piston cylinder 23. The negative pressure adsorbs the paper tray through the ventilation grooves 26 to prevent the paper tray from moving, playing a role in further limiting.

[0030] The edge cutting component 4 is arranged in the middle of the other side of the upper surface of the machine frame 1 and is used for edge cutting the paper tray. The edge cutting component 4 includes a third air cylinder 41 fixed in the middle of the other side of the upper surface of the machine frame 1. Guide plates 42 are arranged on both sides of the third air cylinder 41. An installation plate 43 is arranged between the upper ends of the two guide plates 42. The output end of the third air cylinder 41 is connected with the bottom of the installation plate 43. The third air cylinder 41 drives the installation plate 43 to move up and down. The two guide plates 42 play a guiding role to make the installation plate 43 move vertically up and down. In the middle of one side of the installation plate 43, a motor 44 is fixed. The output end of the motor 44 is connected with a cutting piece 45. The cutting piece 45 includes a protective cover fixed at one end of the motor 44. A cutting blade is arranged inside the protective cover. The middle of the cutting blade is fixedly connected with the output shaft of the motor 44. The motor 44 drives the cutting blade to rotate to cut the paper tray. The cutting blade corresponds to the cutting groove 14 to avoid damaging the placing plate 12 during edge cutting.

[0031] The second implementation mode is mainly different from the first implementation mode in that: there is an adjusting component 3. The adjusting component 3 is arranged on the placing plate 12 and is connected to the fixing frame 13, and is used to adjust the trimming position of the paper tray. The adjusting component 3 includes an adjusting plate 31 arranged on one side of the upper surface of the placing plate 12. The adjusting plate 31 is arranged in an L-shaped structure. The middle part of one side of the adjusting plate 31 is movably connected with a screw rod 32 through a bearing. A screw groove 33 is opened in the middle of the lower end of the fixing frame 13. One end of the screw rod 32 penetrates through the screw groove 33 and is fixed with a knob 34. The screw rod 32 is driven to rotate by the knob 34. The screw rod 32 cooperates with the screw groove 33 to drive the adjusting plate 31 to move on the placing plate 12, so as to adjust the trimming position of the paper tray, thereby improving the trimming accuracy of the device. Both sides of one side of the adjusting plate 31 are fixed with guide rods 35. Guide grooves 36 are opened on both sides of the lower end of the fixing frame 13. One end of the guide rod 35 is connected through the guide groove 36. The cooperation between the guide rod 35 and the guide groove 36 plays a guiding role.

[0032] When the device is working, first adjust the trimming position of the paper tray. At this time, turn the knob 34. The knob 34 drives the screw rod 32 to rotate. The screw rod 32 cooperates with the screw groove 33 to drive the adjusting plate 31 to move until the distance between the adjusting plate 31 and the cutting groove 14 is the trimming distance of the paper tray. At this time, place the paper tray on the placing plate 12 and make the paper tray fit with the adjusting plate 31. Then start the first air cylinder 21. The first air cylinder 21 drives the pressing plate 22 to move downward until the rubber pad 25 on the pressing plate 22 contacts the paper tray to limit the paper tray. Then start the second air cylinder 24. The second air cylinder 24 drives the piston to move upward in the piston cylinder 23, so that negative pressure is generated in the piston cylinder 23. The piston cylinder 23 with negative pressure adsorbs the paper tray through the air vent groove 26 to prevent the paper tray from moving, improving the trimming accuracy of the paper tray. Then start the third air cylinder 41. The third air cylinder 41 drives the motor 44 to move downward through the mounting plate 43 until the cutting blade on the cutting member 45 is inserted into the cutting groove 14. Then start the motor 44. The motor 44 drives the cutting blade to rotate. Then start the linear guide rail 11. The linear guide rail 11 drives the placing plate 12 to move. The placing plate 12 drives the paper tray to move to the position of the cutting blade and continues to move, so that the cutting blade trims the paper tray.
