It should be noted that the following are only some specific embodiments of the present utility model, and the specific and direct descriptions of related structures are merely for the convenience of understanding the present utility model; the specific features do not necessarily or directly limit the scope of implementation of the present utility model.

[0053] Example 1:

[0054] like Figures 1-3 As shown, this utility model discloses a motor-driven lifting cutting device, comprising:

[0055] Carrier 1;

[0056] The first motor drive mechanism 2 has an output end facing left and right, and a first coupling member 21 is provided on the output end of the first motor drive mechanism 2. A second coupling member 22 is provided on the first coupling member 21 that is eccentrically arranged with the output end of the first motor drive mechanism 2.

[0057] The knife holder 3 is arranged on the carrier 1 in vertical sliding mode, and the coupling track 31 extending forward and backward is arranged on the knife holder 3, and the second coupling member 22 is matched in the coupling track 31;

[0058] The cutting structure 4 is fixedly installed on the knife holder 3;

[0059] The coupling structure is formed by the combination of the first coupling member 21 and the second coupling member.

[0060] When the cutting structure 4 needs to be lifted, the first motor driving mechanism 2 works to drive the first coupling member 21 to rotate, so that the knife holder 3 and the cutting structure 4 are lifted through the cooperation of the second coupling member 22 and the coupling track 31.

[0061] Therefore, when the cutting structure 4 needs to cut or stop cutting the paperboard 9, the first motor driving mechanism 2 is controlled to work, the first motor driving mechanism 2 rotates and outputs, and the linkage of the cutting structure 4 is quickly lifted under the action of the rigidly matched linkage and the coupling track 31, which has a shorter reaction time compared with the cylinder driving, so that the longitudinal cutting precision is higher when the paperboard 9 is continuously transmitted, and the transmission of the paperboard 9 is stopped at the beginning and end of the longitudinal cutting, and then the knife holder 3 is lifted, so that the transmission stopping time is shortened to improve the production efficiency.

[0062] In addition, if the first motor driving mechanism 2 works without stopping, the knife holder 3 can reciprocate up and down, and the cutting lines are formed at intervals when the paperboard 9 is transmitted, so that the function is more diversified.

[0063] Preferably, the first motor driving mechanism 2 is arranged on the left side of the carrier 1, and the carrier 1 is perforated, so that the first coupling member 21 passes out from the left side of the carrier 1 to the right side of the carrier 1, the knife holder 3 is arranged on the right side of the carrier 1 and is slidably installed on the carrier 1 through the cooperation of the guide rail and the sliding block, so that the structure is distributed on both sides of the carrier 1, and the structure is more compact and orderly.

[0064] Preferably, the second coupling member 22 is a roller rotatably arranged on the first coupling member 21; correspondingly, the width of the coupling track 31 and the diameter of the second coupling member 22 are matched, so that the second coupling member 22 and the coupling track 31 are rollingly matched to improve the smoothness.

[0069] Therefore, when the paperboard 9 is transmitted, the paperboard 9 is more flatly transmitted by the first guide plate 5 limiting the paperboard 9 above the paperboard 9, and the setting of the lower knife hole 51 makes the paperboard 9 cut in the state of being limited by the first guide plate 5, so that the position of the paperboard 9 cut by the knife head 41 of the cutting structure 4 is more accurate.

[0070] Preferably, the left side of the first guide plate 5 is provided with a first inclined portion 52 inclined upward, so that the paperboard 9 is more smoothly guided into the lower side of the first guide plate 5.
