[0021] Example 1

[0022] See also Figure 1-4 The utility model provides the following technical solutions: a carton production cutting device, including a cutting table 4, a fixing component 6 is installed at the bottom of the cutting table 4, a fixing frame 5 is arranged on the top of the cutting table 4, a frame 1 is installed on the side of the fixing frame 5, a hydraulic cylinder 9 is arranged on the inner top of the frame 1, a lifting plate 2 is connected to the bottom of the hydraulic cylinder 9, an auxiliary component 3 is installed on the top of the lifting plate 2, a cutting knife 7 is connected to the bottom of the lifting plate 2, and a ruler 8 is installed on the side of the frame 1.

[0023] Specifically, the fixing assembly 6 includes a transmission frame 61, a screw 62, a bevel gear 1 63, a bevel gear 2 64, a control rod 65 and a pressure plate 66. A screw 62 is installed at the bottom of the cutting table 4, the bottom end of the screw 62 is connected to the bevel gear 1 63, a control rod 65 is arranged on the side of the bevel gear 1 63, and the side end of the control rod 65 is connected to the bevel gear 2 64. Pressure plates 66 are arranged on both sides of the interior of the fixing frame 5, and the sides of the pressure plate 66 are connected to the transmission frame 61, and the sides of the bevel gear 1 63 and the bevel gear 2 64 are meshed with each other.

[0024] By adopting the above technical solution, the control rod 65 is rotated to drive the bevel gear 2 64 to rotate. Under the meshing transmission between the bevel gear 2 64 and the bevel gear 1 63, the screw rod 62 can be driven to limit its rotation. Under the meshing connection between the screw rod 62 and the transmission frame 61, the sliding limit between the transmission frame 61 and the cutting table 4 can enable the transmission frame 61 to drive the two pressing plates 66 to move downward to complete the pressing and fixing of the cardboard, which can make the installation and positioning effect of the cardboard better and the operation simpler.

[0025] Specifically, a positioning block 67 is disposed on the bottom surface of the cutting table 4 , and a positioning sleeve 68 is connected to the top end of the screw rod 62 inside the positioning block 67 .

[0026] By adopting the above technical solution, the positioning sleeve 67 limits the positioning block 68, so that the bevel gear 1 63 can drive the screw 62 to limit the rotation, so that the transmission control effect of the pressure plate 66 is better.

[0027] Specifically, the side end of the control rod 65 is in an L-shaped structure, and a limited rotation structure is provided between the control rod 65 and the cutting table 4 .

[0028] By adopting the above technical solution, the L-shaped handle is convenient for rotating the control lever 65 to drive the bevel gear 2 64 to rotate, which can make the rotation operation of the bevel gear 2 64 more labor-saving and convenient.

[0029] When this embodiment is used, the cardboard for carton production is placed in the fixed frame 5 of the cutting table 4, and the control rod 65 is rotated to drive the bevel gear 2 64 to rotate. Under the meshing transmission between the bevel gear 2 64 and the bevel gear 1 63, the positioning sleeve 67 limits the positioning block 68, so that the bevel gear 1 63 drives the screw rod 62 to limit its rotation. Under the meshing connection between the screw rod 62 and the transmission frame 61, the sliding limit between the transmission frame 61 and the cutting table 4 can make the transmission frame 61 drive the two pressing plates 66 to move down to complete the pressing and fixing of the cardboard, so that the installation and positioning effect of the cardboard is better and the operation is simpler. Then, the cutting length of the cardboard is adjusted by the ruler 8, and the hydraulic cylinder 9 inside the frame 1 drives the lifting plate 2 to drive the cutting knife 7 to move down to complete the cutting of the cardboard.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the auxiliary component 3 includes a bracket 31, a spring 32, a pressure piece 33 and a connecting plate 34, brackets 31 are provided on both sides of the top of the lifting plate 2, two pressure pieces 33 are embedded in the interior of the lifting plate 2, the sides of the two pressure pieces 33 are connected to the connecting plates 34, and two springs 32 are connected between the connecting plates 34 and the bracket 31.

[0032] Specifically, two sliding grooves are provided inside the lifting plate 2 , and the side edges of the connecting plate 34 are tightly fitted with the inner wall of the bracket 31 .

[0033] By adopting the above technical solution, the elastic force of the spring 32 inside the bracket 31 can make the connecting plate 34 drive the pressing piece 33 to move downward to a limited position, and the pressing piece 33 presses the cardboard on both sides of the cutting knife 7 to prevent the cardboard from moving and twisting when being cut and pressed.

[0034] When this embodiment is used, the pressing piece 33 will first contact the cardboard when the cutting knife 7 moves downward. Under the elastic force of the spring 32 inside the bracket 31, the connecting plate 34 can drive the pressing piece 33 to move downward within a limited position. The pressing piece 33 presses the cardboard on both sides of the cutting knife 7, which can make the cutting accuracy of the cardboard of this carton production cutting device higher.

[0035] The structure and use principle of the frame 1, lifting plate 2, cutting table 4, fixed frame 5, cutting knife 7, ruler 8 and hydraulic cylinder 9 in the utility model have been disclosed in Chinese patent application No. 202222456023.6 which discloses a cutting device for carton production. Its working principle is to place the cardboard for carton production in the fixed frame 5 of the cutting table 4, and then adjust the cutting length of the cardboard by the ruler 8. The hydraulic cylinder 9 inside the frame 1 drives the lifting plate 2 to drive the cutting knife 7 to move downward to complete the cutting of the cardboard.

[0036] Working principle and use process of the utility model: When the utility model is used, the cardboard for carton production is placed in the fixed frame 5 of the cutting table 4, and the control rod 65 is rotated to drive the bevel gear 2 64 to rotate. Under the meshing transmission between the bevel gear 2 64 and the bevel gear 1 63, the positioning sleeve 67 limits the positioning block 68 so that the bevel gear 1 63 drives the screw 62 to limit the rotation, and under the meshing connection between the screw 62 and the transmission frame 61, the sliding limit between the transmission frame 61 and the cutting table 4 can make the transmission frame 61 drive the two pressing plates 66 to move down to complete the cardboard cutting. The pressing and fixing can make the installation and positioning effect of the cardboard better and the operation simpler. Then, the cutting length of the cardboard is adjusted by the ruler 8. The hydraulic cylinder 9 inside the frame 1 drives the lifting plate 2 to drive the cutting knife 7 to move downward to complete the cutting of the cardboard. When the cutting knife 7 moves downward, the pressing piece 33 will first contact the cardboard. Under the elastic force of the spring 32 inside the bracket 31, the connecting plate 34 can drive the pressing piece 33 to move downward in a limited manner. The pressing piece 33 presses the cardboard on both sides of the cutting knife 7, which can make the cutting accuracy of the cardboard of this carton production cutting device higher.
