DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figure 1 As shown, a cross-cutting machine for easy replacement of blades includes a base 1, a knife holder 5 and a cutter assembly 7. A feeding table 2 is provided on one side of the upper side of the base 1, and a support column 3 is fixed below the base 1. Side frames 4 are fixed on both sides of the upper side of the base 1, and a knife holder 5 is slidably provided between the side frames 4. A lifting assembly 6 is installed on the outer side of the knife holder 5, and the lifting assembly 6 includes a cylinder 601, a piston rod 602 and a fixed plate 603. The cylinder 601 is installed on the upper side of the side frame 4, and the lower side of the cylinder 601 is provided with a piston rod 602 penetrating the side frame 4. The bottom of the piston rod 602 is connected to a fixed plate 603, and the fixed plate 603 is fixedly connected to the knife holder 5; the middle part of the side frame 4 corresponding to the mounting frame 701 is a hollow structure;

[0022] The specific operation is as follows: the cylinder 601 and the piston rod 602 are used to drive the fixed plate 603 and the tool holder 5 to rise and fall, so that the tool holder 5 can drive the cutter 706 on one side to cut the packaging cardboard fed from the upper surface of the base 1, and the inclined unloading platform 2 is used to facilitate the unloading of the packaging cardboard after cutting.

[0023] like Figure 2-Figure 3As shown, a cutter assembly 7 is installed on the inner side of the tool holder 5, and the cutter assembly 7 includes a mounting frame 701, a driving motor 702, a bidirectional screw rod 703, a movable sleeve 704, a blade mounting seat 705, a cutter 706, a spring frame 707 and a rubber gasket 708. The mounting frame 701 is fixedly connected to the side frame 4, and a driving motor 702 is installed inside the mounting frame 701. A bidirectional screw rod 703 is arranged on one side of the driving motor 702, and two movable sleeves 704 are sleeved on the outer side of the bidirectional screw rod 703. Blade mounting seats 705 are fixed below the two movable sleeves 704, and a cutter 706 is arranged on the inner side between the blade mounting seats 705. A spring frame 707 is protruded from the outer side of the blade mounting seat 705, and a rubber gasket 708 is fixed to one end of the spring arranged inside the spring frame 707; a slide groove 8 is opened in the middle of the tool holder 5, and the blade mounting seat 705 is slidably connected to the slide groove 8;

[0024] The specific operation is as follows: the driving motor 702 is used to drive the rotation of the bidirectional screw rod 703, and then the two movable sleeves 704 outside the bidirectional screw rod 703 are driven to move, so that the two blade mounting seats 705 move toward or in the opposite direction. The cutter 706 is arranged between the two blade mounting seats 705. The two blade mounting seats 705 move toward each other to clamp the cutter 706. At the same time, the rubber gasket 708 can fit tightly with the side of the cutter 706 under the action of the spring inside the spring frame 707. The large friction of the rubber gasket 708 is conducive to tightening the side of the cutter 706. Conversely, the two blade mounting seats 705 move in the opposite direction to expose the cutter 706, so as to facilitate the quick replacement of the cutter 706 without frequent disassembly and assembly of bolts.

[0025] like Figure 1-Figure 2 As shown, a feeding assembly 9 is installed below the two side frames 4, and the feeding assembly 9 includes an electric lifting rod 901 and a mounting plate 902, a mounting plate 902 is fixed below the electric lifting rod 901, and two electric lifting rods 901 and mounting plates 902 are symmetrically arranged about the center line of the base 1; the feeding assembly 9 also includes a leveling roller 903, a feeding roller 904 and a rotating motor 905, the leveling roller 903 and the feeding roller 904 are rotatably arranged between the mounting plates 902 through a rotating shaft, and a rotating motor 905 is installed outside the rotating shaft of the feeding roller 904, and the rotating shafts of the leveling roller 903 and the feeding roller 904 are connected through a transmission belt transmission;

[0026] The specific operation is as follows: the electric lifting and retracting rod 901 is used to easily adjust the height of the leveling roller 903 and the feeding roller 904, which is suitable for packaging cardboards of different thicknesses; the rotating motor 905 is used to easily drive the leveling roller 903 and the feeding roller 904 to rotate, so that the feeding roller 904 can feed the packaging cardboard.

[0027] like Figure 1-Figure 2As shown, the limited position correction assembly 10 is installed on both sides of the middle position of the base 1, and the limited position correction assembly 10 includes a side plate 1001, an electric push rod 1002 and a correction plate 1003, the side plate 1001 is fixedly connected to the base 1, and the electric push rod 1002 is installed on the inner side of the side plate 1001, and the correction plate 1003 is fixed to one end of the electric push rod 1002;

[0028] The specific operation is as follows: the electric push rod 1002 is conveniently extended and pushed to push the deflection correction plate 1003, so that the deflection correction plate 1003 can limit and correct the deflection of both sides of the packaging cardboard during the feeding process.

[0029] In summary, if Figure 1-Figure 3 As shown, the cross-cutting machine with easy blade replacement, when in use, firstly, the height of the leveling roller 903 and the feeding roller 904 can be adjusted by telescopically adjusting the electric lifting and retracting rod 901 to be suitable for packaging cardboards of different thicknesses, and then the rotation motor 905 drives the leveling roller 903 and the feeding roller 904 to rotate, so that the feeding roller 904 can feed the packaging cardboard, and the electric push rod 1002 can be telescopically pushed to push the correction plate 1003, so that the correction plate 1003 can limit and correct the two sides of the packaging cardboard during the feeding process, and then the cylinder 601 and the piston rod 602 drive the fixed plate 603 and the knife holder 5 to rise and fall, so that the knife holder 5 can drive the cutter 706 on one side to cut the packaging cardboard fed from the upper surface of the base 1;

[0030] When the cutter 706 needs to be replaced, the bidirectional lead screw 703 can be driven to rotate by the driving motor 702, thereby driving the movement of the two movable sleeves 704 outside the bidirectional lead screw 703, so that the two blade mounting seats 705 move in the opposite direction, and the cutter 706 can be exposed to facilitate the rapid replacement of the cutter 706. The cutter 706 is then reset to be located between the two blade mounting seats 705, and the bidirectional lead screw 703 rotates to drive the two movable sleeves 704 and the blade mounting seats 705 to move toward each other to clamp the cutter 706. At the same time, the rubber gasket 708 can be closely fitted with the side of the cutter 706 under the action of the spring inside the spring frame 707. The large friction force of the rubber gasket 708 is conducive to tightening the side of the cutter 706. Otherwise, the two blade mounting seats 705 move in the opposite direction, thus completing the use process of the cross-cutting machine that is easy to replace the blade.
