[0002] Low-formaldehyde furniture impregnated film paper is a kind of sizing paper obtained by impregnating a plain paper or a printed decorative paper with a low-formaldehyde or formaldehyde-free amino resin, drying to a certain degree, and having a certain resin content and volatile content. It can be glued to each other or to a wood-based panel substrate by hot pressing. When producing panel parts, it is necessary to cut the impregnated film paper according to the required length. During the cutting process, generally, one end of the impregnated film paper needs to be pulled and fixed, and then the impregnated film paper of the required length is cut.

[0017] Preferably, a cutting method for a positioning type low - formaldehyde furniture impregnated film paper is as follows:

[0018] S1. Installation of impregnated film paper: After unscrewing the limit screw ring, install the impregnated film paper roll outside the fixed shaft. Then, after screwing on the limit screw ring, limit the impregnated film paper roll through the limit plate and the limit screw ring.

[0019] S2. Fixing the end of the paper: Pull the impregnated film paper between the two transverse frames on the paper cutting unit on the side away from the fixed shaft.

[0020] S3. Smoothing the paper: Move the two transverse frames on the paper cutting unit on the side close to the fixed shaft closer to each other so that the contact roller contacts the paper surface. Drive this paper cutting unit towards the fixed shaft to smooth the paper, and determine the moving distance through the measuring scale, thereby determining the length of the paper.

[0021] S4. Cutting the paper: Turn on the storage battery switch to energize the electromagnet to generate a repulsive force on the magnetic block, drive the cutting knife towards the paper, and cut the paper.

[0022] S5. Subsequent paper unfolding and cutting: After cutting the paper, one end of the paper is clamped on the paper cutting unit close to the fixed shaft. Then, drive the paper cutting unit to move towards the end position on the side away from the fixed shaft, and move the other paper cutting unit towards the fixed shaft to smooth the paper. The two paper cutting units alternately perform paper end clamping and paper smoothing and cutting.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1) During operation, the two paper cutting units provided respectively fix the end of the paper and smooth the paper. The two paper cutting units are respectively installed on two sliding seats on both sides of the top of the cutting seat, which is convenient to drive the two paper cutting units to move alternately, so that the two paper cutting units alternately perform paper end clamping and paper smoothing and cutting. After cutting the paper once, it is not necessary to manually pull one end of the paper for fixing, which is convenient for paper cutting and improves the paper cutting effect.

[0025] 2) During operation, after the set extrusion slope contacts the surface of the paper, the transverse frame moves toward the fixed axis to smooth the paper and keep the paper horizontal. The paper is limited by the limit plate and the end screw, so as to facilitate the positioning of the paper. A cutting knife is arranged between the two contact rollers, so that after the paper is cut, the end of the paper can be clamped to facilitate subsequent cutting.

[0026] 3) During operation, when the horizontal frame is fixed, the pressing block in its original state presses the bottom of the extrusion slope against the pressure convex block, so that the second spring is compressed and the pressing plate presses and fixes the contact roller. When the horizontal frame moves, the generator generates electricity to make the electromagnet generate attraction to the magnetic block, driving the second spring to open, and the pressing plate no longer presses the contact roller, so that the friction force of the extrusion slope on the paper during fixing is greater than the friction force of the extrusion slope on the paper during smoothing, thereby preventing the paper from being pulled and torn during smoothing.

[0027] 4) During operation, when the sliding seat moves toward one side of the fixed shaft, the pinion generates electricity and outputs it to the electromagnet under the action of the fixed tooth plate and the rotating tooth plate, which is convenient for driving the second spring to open, so that the pressure plate and the contact roller are loosened, which is convenient for smoothing. When the switch is turned on, it is convenient to drive the cutting knife to move for cutting, and the generator is connected in parallel with the battery, and the current direction of the input electromagnet is opposite, which is convenient for driving the extrusion wedge block to move in two directions, so as to facilitate the execution of two different actions;

[0028] 5) During operation, a limit stop is set on the side of the rotating tooth plate close to the fixed shaft, and the rotating tooth plate cannot rotate toward the limit stop. When the transverse frame moves toward the fixed shaft, the small gear can continuously rotate to generate electricity. When the transverse frame moves back, the fixed tooth plate can drive the rotating tooth plate to rotate, so that the generator does not generate electricity, ensuring that the end of the paper is clamped and fixed, which is convenient for the unfolding and fixing of the paper.

The generator 3456 is fixedly installed on the sliding seat 32. The electromagnet 3387 is connected in series with the generator 3456 and the rectifier. When the transverse frame 332 is fixed, in the original state, the pressing block 3374 makes the bottom of the pressing inclined surface 3375 press tightly against the pressed convex block 33513, so that the second spring 33511 is compressed and the pressing plate 3358 presses and fixes the contact roller 3357. When the transverse frame 332 moves, the electricity generated by the generator 3456 makes the electromagnet 3387 generate an attractive force on the magnetic block 3386, driving the second spring 33511 to open, and the pressing plate 3358 no longer presses the contact roller 3357 tightly. Thus, the frictional force of the pressing inclined surface 3375 on the paper during fixation is greater than the frictional force of the pressing inclined surface 3375 on the paper during smoothing, preventing the paper from being torn when the paper is smoothed. The circuit where the generator 3456 is located and the circuit where the storage battery is located are connected in parallel. When the sliding seat 32 moves towards the fixed shaft 22, under the action of the fixed toothed plate 3453 and the rotating toothed plate 3443, the small gear 3455 generates electricity and outputs it to the electromagnet 3387, facilitating driving the second spring 33511 to open, loosening the pressing plate 3358 from the contact roller 3357, and facilitating smoothing. When the switch is turned on, it is convenient to drive the cutting knife 3364 to move for cutting. Moreover, the generator 3456 is connected in parallel with the storage battery, and the current direction input to the electromagnet 3387 is opposite, facilitating driving the extrusion wedge block 3381 to move in two directions and facilitating driving the execution of two different actions.

[0056] Working principle: During operation, first unscrew the limit screw ring 25, then sleeved a roll of impregnated film paper to be cut outside the fixed shaft 22, and then screw on the limit screw ring 25. The impregnated film paper roll is limited by the limit plate 23 and the limit screw ring 25. In the original state, the two cross frames 332 on the paper cutting unit 33 near the fixed shaft 22 are in an open state, and the two cross frames 332 on the paper cutting unit 33 far from the fixed shaft 22 are in a closed state. The paper cutting unit 33 near the fixed shaft 22 is a paper flattening part, and the paper cutting unit 33 far from the fixed shaft 22 is an end clamping part. Pull one end of the impregnated film paper towards the end clamping part, and at the same time turn on the top motor 334 of the end clamping part to drive the two cross frames 332 to move away from each other, insert one end of the impregnated film paper between the two cross frames 332, and drive the two cross frames 332 to move closer to clamp the end of the impregnated film paper;

[0057] At this time, the sliding seat 32 of the end clamping part is correspondingly located at the end position of the measuring scale 343 on the transverse narrow plate 341. Then turn on the top motor 334 of the paper flattening part to drive the upper and lower cross frames 332 to move closer to each other, so that the contact roller 3357 contacts the paper surface. Turn on the side motor 36 of the paper flattening part at will to drive the paper flattening part to move towards the fixed shaft 22 side, flatten the paper and make the paper in a horizontal state until the sliding seat 32 moves through the measuring scale 343 to the target position. The distance between the paper end and the paper cutting position is the required cutting length of the paper, which is convenient for positioning and cutting the paper;

[0058] In the original state, the bottom end of the extrusion inclined surface 3375 contacts the pressed convex block 33513, so that the second spring 33511 is in a compressed state, and the pressing plate 3358 presses the contact roller 3357 tightly. When the paper flattening part moves towards the fixed shaft 22 side, since the limit stop block 3446 is arranged on the side of the rotating toothed plate 3443 close to the fixed shaft 22, the rotating toothed plate 3443 cannot rotate towards the limit stop block 3446 side, and the fixed toothed plate 3453 meshes with the rotating toothed plate 3443. Therefore, during the movement, the large gear 3454 rotates continuously, and then drives the small gear 3455 to rotate continuously, so that the generator 3456 generates electricity. After the current passes through the rectifier and is introduced into the electromagnet 3387, the electromagnet 3387 is energized to generate an attraction force on the magnetic block 3386, so that the connecting frame 3382 moves towards the fixed box 3383 side. At this time, the connecting plate 33512 moves back under the elastic force of the second spring 33511, so that the pressing plate 3358 no longer presses the contact roller 3357 tightly. When the paper flattening part moves, the contact roller 3357 can rotate freely, which is convenient for flattening. And the frictional clamping force of the end pressing part on the paper is greater than the frictional force of the paper flattening part on the paper, avoiding tearing the paper during flattening and protecting the paper;

[0059] When the paper flattening member moves to the target position, the generator 3456 stops outputting current, causing the extrusion wedge block 3381 to move back, pressing the pressing block 3374 to move towards the inside of the internal installation groove 3352, generating pressure on the pressed convex block 33513, pushing the connecting plate 33512 to move downward, and causing the pressing plate 3358 to press the contact roller 3357 tightly;

[0060] During cutting, the switch connecting the storage batteries in series is turned on, causing the electromagnet 3387 to be energized, and the current passing through it is in the opposite direction to the current generated and output by the generator 3456. This causes the electromagnet 3387 to generate a repulsive force on the magnetic block 3386, pushing the extrusion wedge block 3381 to move towards the side away from the fixed box 3383, pushing the pressing block 3374 to move towards the pushing groove 3369, pushing the horizontal push rod 3367 to move towards the inside of the internal limiting groove 3361, and pushing the cutting knife 3364 to move towards the paper through the connecting rod 3368, causing the two cutting knives 3364 to cut the paper;

[0061] After cutting is completed, the switch is turned off, causing the horizontal frame 332 to return to its original state. After the two horizontal frames 332 of the end clamping member are opened away from each other, the paper flattening member is driven to move towards the end clamping member, causing the paper flattening member to move to the end position to become the new end clamping member. After the original end clamping member moves a certain distance towards the fixed shaft 22, the two horizontal frames 332 are driven to move closer to each other, causing the contact roller 3357 to contact the paper surface, forming a new paper flattening member, and then the above-mentioned flattening and cutting operations are performed again, and then the paper is continuously cut;

[0062] During the backward movement of the paper flattening member, since the rotating toothed plate 3443 can rotate towards the side away from the limit stop block 3446, when the paper flattening member moves backward, the circular plate 3452 will not rotate, causing the electromagnet 3387 not to be energized, and causing the contact roller 3357 not to rotate when the paper flattening member moves backward, clamping and pulling the paper, which is convenient for the paper to be wound out.
