[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] Example 1: Figure 1 As shown, a high-precision and high-efficiency packaging bag cutting device includes a control unit 1 and a cutting unit 2. The cutting unit 2 includes a mesh fence 3 and a cutting mechanism 4. The mesh fence 3 is provided with a plurality of cutting openings 5 ​​arranged in a square array, and each cutting opening 5 is provided with a cutting mechanism 4; wherein the control unit 1 is arranged above the cutting unit 2, and the cutting mechanism 4 is electrically connected to the control unit 1.

[0027] Preferably, if Figure 2-5 As shown, the cutting mechanism 4 includes a front support plate 6, a rear support plate 7, a guide plate 8, a guide wheel 9, a connecting rod 10, and a blade 11;

[0028] The front support plate 6 and the rear support plate 7 are arranged longitudinally, and the inner sides of the front support plate 6 and the rear support plate 7 are relatively located, and the track A12 and the track B13 are respectively vertically provided; the track A12 and the track B13 are both provided with sliding blocks, and the upper ends of the sliding blocks are connected to the telescopic cylinders;

[0029] The connecting rod 10 is a cylindrical crossbar structure, and sliding blocks are horizontally penetrated at the left and right ends of the connecting rod 10; a blade 11 and a guide wheel 9 are fixedly penetrated in the middle of the connecting rod 10;

[0030] The guide plate 8 is vertically fixed to the left side of the front side track B13 of the rear support plate 7, and a row of tooth grooves A14 is provided on the right side of the lower end of the guide plate 8;

[0031] The outer side of the guide wheel 9 is provided with a tooth groove B15, and the tooth groove A14 and the tooth groove B15 are meshed with each other.

[0032] Preferably, the length of the tooth groove B15 is one quarter of the circumferential length of the guide wheel 9, and the length of the tooth groove A14 is consistent with that of the tooth groove B15.

[0033] Preferably, when the guide wheel 9 is located at the bottom of the tooth groove A14, the cutting edge of the blade 11 is vertically downward; when the guide wheel 9 is located at the top of the tooth groove A14, the blade 11 is vertically arranged, and the cutting edge of the blade 11 is vertically facing right.

[0034] Preferably, when the cutting edge of the blade 11 in each cutting opening 5 is pointing vertically downward, the blades 11 in the same row are located on the same straight line and are closely connected.

[0035] In the specific implementation of the present invention, the working principle of the cutting mechanism 4 is as follows: the telescopic cylinder drives the sliding block to move downward, so that the connecting rod 10 drives the blade 11 and the guide wheel 9 to move downward. When the guide wheel 9 moves downward along the guide plate 8 to the top of the tooth groove A14, the guide wheel 9 does not rotate, so the blade 11 Figure 4 As shown, the blade 11 is always pointing vertically to the right. When the guide wheel 9 continues to move downward, the tooth groove B15 on the guide wheel 9 begins to mesh with the tooth groove A14 of the guide plate 8, and the guide wheel 9 rotates clockwise. Since the length of the tooth groove B15 accounts for one-fourth of the circumference of the guide wheel 9, the guide wheel 9 rotates clockwise by 90 degrees, thereby driving the blade 11 to rotate clockwise by 90 degrees during the downward movement through the connecting rod 10, and becomes Figure 5 Status shown.

[0036] In the specific implementation of the utility model, the control unit 1 controls the working condition of the cutting mechanism 4 in each cutting opening 5, adjusts the desired cutting length, and realizes cutting of packaging bags of different sizes. This process does not require the replacement of blades, thereby improving production efficiency; at the same time, the control unit 1 controls the cutting mechanism 4 that needs to work, thereby improving cutting accuracy.

[0037] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
