[0002] Melamine impregnated paper, the full name is melamine impregnated film paper, also known as "melamine" paper, is a kind of plain paper or printed decorative paper impregnated with amino resin and dried to a certain degree, with a certain resin content and volatile content. It can be glued to each other or to the artificial board substrate by hot pressing. In the production process of melamine impregnated paper, a cutting device is usually used to cut the impregnated paper tape that has been impregnated and dried into sections. For example, the patent with the publication number CN211388933U proposes a cutting device for melamine impregnated paper. This device first controls the cutting mechanism to move downward by an electric telescopic rod, and then drives the cutting mechanism to move from left to right by a slider, so as to complete the cutting of the impregnated paper tape. However, when the width of the impregnated paper tape is relatively wide, the cutting mechanism needs to move a relatively long distance to cut off the impregnated paper tape, resulting in low cutting efficiency. Moreover, during the process of the cutting mechanism cutting the impregnated paper tape, since the impregnated paper tape is not fixed, the front section of the impregnated paper tape may skew in the translation direction of the cutting mechanism during cutting, causing the impregnated paper tape to be cut obliquely, which affects the finished product quality of the impregnated paper.

Two rows of vertical sliding rods 5 are slidably installed on the bottom plate 4. A strip-shaped pressing plate 6 is installed at the bottom of each row of sliding rods 5. A spring 7 is sleeved on each sliding rod 5, and the spring 7 abuts between the bottom plate 4 and the strip-shaped pressing plate 6. A blade 8 that is horizontally left and right and perpendicular to the horizontal plane is installed at the bottom of the bottom plate 4. The blade 8 is located between the two rows of sliding rods 5. When there is no external force squeezing the spring 7, the blade 8 is located above the two strip-shaped pressing plates 6. A support plate 9 is installed between the left and right inner side walls of the first U-shaped frame 1. The support plate 9 is located directly below the strip-shaped pressing plate 6 and the blade 8. An inclined slope is provided in front of the support plate 9. A gap that is horizontally left and right and vertically penetrates the support plate 9 is opened on the support plate 9. The gap is located directly below the blade 8. The length of the gap is slightly greater than the length of the blade 8, and the width of the gap is slightly greater than the thickness of the blade 8. When cutting the impregnated paper tape, the hydraulic cylinder 3 will drive the bottom plate 4 to move downward. The two strip-shaped pressing plates 6 will first contact the impregnated paper tape, and then the bottom plate 4 will continue to move downward to compress the spring 7. The impregnated paper tape is tightly pressed on the support plate 9 through the strip-shaped pressing plate 6, and then the blade 8 contacts the impregnated paper tape and cuts the impregnated paper tape. The left edge of the blade 8 of the blade 8 slopes upward by about 2 degrees - 5 degrees. When the blade 8 moves downward, it will cut the impregnated paper tape from right to left. Two stop rods 10 are installed between the left and right inner side walls of the first U-shaped frame 1. Both of the two stop rods 10 are located above the support plate 9. The two strip-shaped pressing plates 6 are located between the two stop rods 10. The function of setting the stop rods 10 is to prevent the strip-shaped pressing plates 6 and the blade 8 from lifting the impregnated paper when moving upward.

[0020] A set of electric push rods 11 with output rods perpendicular downward are installed at the bottom of the cross plate of the first U-shaped frame 1. The end of the output rod of the electric push rod 11 is installed with a second U-shaped frame 12 that is flipped 90 degrees. A first roller 13 is rotatably installed on the second U-shaped frame 12. A second roller 14 is rotatably installed between the left and right inner side walls of the first U-shaped frame 1. The second roller 14 is located directly below the first roller 13. A servo motor 15 is installed on the outside of the first U-shaped frame 1. The output shaft of the servo motor 15 is connected to the main shaft of the second roller 14. The first roller 13 can be driven to move downward by the electric push rod 11, so that the first roller 13 and the second roller 14 cooperate to clamp the impregnated paper tape. Then, the second roller 14 is driven to rotate by the servo motor 15, and the impregnated paper tape can be pushed forward. By controlling the number of rotation circles of the output shaft of the servo motor 15, the pushing length of the impregnated paper tape can be controlled. A controller is also provided on this device to control the hydraulic cylinder 3 and the servo motor 15. Before using the device, the length of the impregnated paper is set on the controller. When the servo motor 15 pushes out the impregnated paper tape of the preset length each time, the servo motor 15 is turned off. After the hydraulic cylinder 3 drives the blade 8 to complete a cutting operation, the servo motor 15 starts again. A conveyor belt 16 is provided in front of the first U-shaped frame 1. The entrance of the conveyor belt 16 is arranged below the support plate 9. The cut impregnated paper can be conveyed forward through the conveyor belt 16.

[0021] The working principle and usage process of the present utility model: When using this melamine impregnated paper cutting device, the front end of the impregnated paper tape is passed through between the first roller 13 and the second roller 14, and between the support plate 9 and the stop rod 10. Then, the first roller 13 is driven to move downward by the electric push rod 11, so that the first roller 13 and the second roller 14 cooperate to clamp the impregnated paper tape. Then, the hydraulic cylinder 3 is manually started once. The hydraulic cylinder 3 drives the bottom plate 4 to move downward horizontally. The two strip-shaped pressing plates 6 will first contact the impregnated paper tape, and then the bottom plate 4 continues to move downward to compress the spring 7. The impregnated paper tape is tightly pressed on the support plate 9 through the strip-shaped pressing plates 6. Then, the blade 8 contacts the impregnated paper tape and cuts off the front end of the impregnated paper tape. Then, the hydraulic cylinder 3 drives the bottom plate 4 to reset. After the cutting operation is completed, the length of the impregnated paper is set, and the just-cut waste is taken away. The device is debugged. Finally, the cutting device and the conveyor belt 16 are started to carry out the cutting work of the impregnated paper.
