[0023] Reference Figs. 1-3This utility model provides an automatic knife locking device for a slitting machine, including symmetrically arranged mounting plates 1. A rotatable bottom knife shaft 2 and a circular knife shaft 3 are located between the two mounting plates 1. The axes of the bottom knife shaft 2 and the circular knife shaft 3 are located in the same plane. A plurality of bottom knives 21 are slidably mounted on the bottom knife shaft 2, and a plurality of circular cutting blades 31 are sleeved on the circular knife shaft 3. Connecting bolts are provided between the bottom knives 21 and the bottom knife shaft 2, and between the circular cutting blades 31 and the circular knife shaft 3. The use of the bottom knife shaft 2 and the circular knife shaft 3 is the same as in the prior art, which is a mature existing technology in this field. The connection and usage principles of the bottom knives 21, the circular cutting blades 31, the circular knife shaft 3, and the bottom knife shaft 2 will not be elaborated here. Both ends of the cutter shaft 2 are rotatably connected to the mounting plate 1, and both ends of the circular cutter shaft 3 are rotatably connected to the sliding seat 5. The sliding seats 5 are all slidably connected to the mounting plate 1 (the mounting plate 1 is provided with a limiting groove 12 that cooperates with the sliding seat 5). One end of the sliding seat 5 is connected to the connecting plate 51, and the end of the connecting plate 51 away from the sliding seat 5 is connected to the mounting seat 52. The mounting seats 52 are all slidably connected to the mounting plate 1 (the mounting plate 1 is provided with a sliding groove 11 that cooperates with the mounting seat 52). The mounting plate 1 is provided with a telescopic member 6, and the output end of the telescopic member 6 is connected to the connecting plate 51. The telescopic member 6 can drive the connecting plate 51, the sliding seat 5, and the mounting seat 52 to move horizontally on the mounting plate 1.

[0024] See Figs. 1-3 Specifically, when it is necessary to provide power to the bottom cutter shaft 2, a motor can be installed at the end of a mounting plate 1 away from the bottom cutter shaft 2, and then the output shaft of the motor can be connected to the bottom cutter shaft 2 through the mounting plate 1 so that it can drive the bottom cutter shaft 2 to rotate.

[0025] See Figs. 1-3 Preferably, both the bottom cutter shaft 2 and the round cutter shaft 3 are fitted with mutually cooperating transmission gears 4. When the bottom cutter shaft 2 and the round cutter shaft 3 approach each other, the two transmission gears 4 mesh with each other, causing the bottom cutter shaft 2 to rotate. The bottom cutter shaft 2 drives the transmission gears 4 on it to rotate. Through the transmission of the two transmission gears 4, the round cutter shaft 3 can be driven to rotate, so that the bottom cutter shaft 2 and the round cutter shaft 3 can rotate at the same time.

[0026] See Figs. 1-3 Furthermore, if the transmission gear 4 is not suitable for the current working environment during actual use, a separate power can be provided for the circular cutter shaft 3. The limiting groove 12 of one of the mounting plates 1 is opened, and a hollow clearance space is formed on the limiting groove 12 to allow the motor output shaft to move. The end of the sliding seat 5 away from the circular cutter shaft 3 is exposed. Then, the motor is set at the end of the mounting plate 1 away from the circular cutter shaft 3, and the motor is slidably connected to the mounting plate 1 (optional slide rail or other structure). Then, the output shaft of the motor passes through the mounting plate 1 and the sliding seat 5 and is connected to the circular cutter shaft 3, so that it can move with the sliding seat 5 and drive the circular cutter shaft 3 to rotate, thus providing a separate power for the circular cutter shaft 3.

[0027] See Figs. 1-3 Preferably, the telescopic component 6 is a cylinder that provides power to the device.

[0028] See Figs. 1-3 Preferably, a stabilizing rod 53 is provided between the two mounting bases 52. Sliding sleeves 54 are symmetrically slidably mounted on the stabilizing rod 53. Slots 531 that mate with the sliding sleeves 54 are symmetrically provided on the stabilizing rod 53. Inserts 541 that mate with the slots 531 are symmetrically provided on each sliding sleeve 54. One end of each insert 541 is inserted into the slot 531 and connected to the others. Each insert 541 inside the stabilizing rod 53 is connected to a top rod 532 that is elastically connected to the inside of the stabilizing rod 53 (a slider is symmetrically provided on the top rod 532 inside the stabilizing rod 53, and a slide rail that mates with the slider is provided inside the stabilizing rod 53. The sliders are slidably disposed within the slide rail, and an elastic element 533 is provided between the slider and the slide rail). The inserts 541 are away from the top rod. One end of each rod 532 is connected to a plug rod 542. The end of each plug rod 542 away from the sliding sleeve 54 is inserted into the mounting base 52 (the mounting base 52 has a plug hole that mates with the plug rod 542). When it is necessary to disassemble the stabilizer rod 53, both sliding sleeves 54 are pushed simultaneously towards the end closest to the center of symmetry. The sliding sleeves 54 drive the plug rod 542 to slide on the stabilizer rod 53. At the same time, the sliding sleeves 54 push the top rod 532. The top rod 532 squeezes the elastic element 533. When the plug rod 542 disengages from the mounting base 52, the sliding sleeve 54 is released. Under the action of the elastic element 533, the top rod 532 drives the sliding sleeve 54 back to its initial position. The structure of the sliding sleeve 54 can be used to achieve quick disassembly and assembly of the stabilizer rod 53.

[0029] See Figs. 1-3 Preferably, the elastic element 533 is a spring, which provides return power.

[0030] See Figs. 1-3 When it is necessary to adjust the bottom cutter 21 and the circular cutter 31, the telescopic component 6 is used to drive the connecting plate 51, the sliding seat 5 and the mounting seat 52 to move horizontally on the mounting plate 1, so that the circular cutter shaft 3 moves away from the bottom cutter shaft 2, and then the bottom cutter 21 and the circular cutter 31 can be adjusted.

[0031] This utility model provides an automatic blade locking device for a slitting machine, including a sliding seat, a connecting plate, and a telescopic component. These components work together to move the circular blade shaft away from the bottom blade shaft when the positions of the bottom blade and the circular cutter need adjustment, saving labor and improving the accuracy of resetting. The top rod and sliding sleeve allow for quick assembly and disassembly of the stabilizing rod, reducing manual operation time. A detachable stabilizing rod is provided between the two mounting seats, establishing a connection between them and improving the stability of the circular blade shaft during movement. In summary, the beneficial effects of this utility model are: saving labor, improving the accuracy of resetting, and enhancing the stability of the circular blade shaft during movement when the positions of the bottom blade and the circular cutter need adjustment.

[0032] Of course, the utility model can also have other various embodiments, and the skilled in the art can make various corresponding changes and deformations according to the utility model without departing from the spirit and essence of the utility model, but these corresponding changes and deformations should all belong to the protection scope of the claims attached to the utility model.
