[0044] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0045] Various non-limiting embodiments of the present invention are described in detail below. Any number of elements in the accompanying drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0046] like Figure 1-Figure 4As shown, a cutting device is arranged obliquely as a whole, extending from front to back and tilted upwards, in order to be integrated with other equipment. The cutting device includes a frame 1, a support plate 8, a cutting assembly, a push-out assembly and a placement table 3. A conveying device is used to transport printed matter to the support plate 8 to wait for cutting by the cutting assembly. After the cutting of the printed matter is completed, the push-out assembly pushes the printed matter cut into two parts to the placement table 3. The placement table 3 is installed at the rear side of the support plate 8 to receive the cut printed matter. The printed matter on the placement table 3 waits to be transported away by the transfer device.

[0047] Specifically, there are two support plates 8, both of which are mounted on the frame 1 through support blocks 14, and both of which are in the same horizontal plane. There is a gap 16 between the two support plates 8, and the length direction of the gap 16 extends along the front-to-back direction. The gap 16 is the position where the cutting assembly cuts. Each support plate 8 is provided with an avoidance hole 13, which is a through hole that passes through the support plate 8 from top to bottom, and extends along the front-to-back direction. In this embodiment, the number of avoidance holes 13 on each support plate 8 is two, and according to actual conditions, the number of avoidance holes 13 on each support plate 8 can also be one or more than three.

[0048] Because the entire cutting device is arranged at an angle, in order to prevent the printed matter conveyed to the supporting plate 8 from sliding off, the front sides of the two supporting plates 8 are provided with flanges 9 extending upward, and the avoidance holes 13 extend through the flanges 9, while the avoidance holes 13 penetrate the rear sides of the supporting plates 8. The flanges 9 here have a protective function and a positioning function. The protective function is to prevent the conveyed printed matter from sliding off the supporting plate 8; the positioning function is: because the cutting device is inclined, when the printed matter reaches the supporting plate 8, one side of the printed matter will abut against the flange 9 and be just aligned, thereby correcting one side of the printed matter.

[0049] The cutting assembly is arranged on the frame 1, and is used for cutting the printed matter on the supporting plate 8, so that a single printed matter becomes two printed matters.

[0050] Specifically, Figure 4As shown, there are two push-out assemblies, each of which is used to push the cut printed matter from the support plate 8 to the placement table 3. The two push-out assemblies are located on the corresponding sides of the support plate 8, that is, one push-out assembly is installed under each support plate 8. Each push-out assembly includes a pneumatic slide 2 and two pushers 15. The pneumatic slide 2 is installed on the frame 1, and the pneumatic slide 2 is located below the corresponding support plate 8. The extension direction of the pneumatic slide 2 is consistent with the extension direction of the avoidance hole 13. The two pushers 15 are both arranged on the pneumatic slide 2. The pushers 15 extend from the avoidance hole 13 to the top of the support plate 8. The pneumatic slide 2 drives the two pushers 15 to move in the corresponding avoidance hole 13, so that the pushers 15 push the printed matter and send the cut printed matter out of the support plate 8. At the same time, because the avoidance hole 13 extends to the flange 9, the push handle 15 can also pass through the flange 9 through the avoidance hole 13, so that the flange 9 will not affect the movement of the push handle 15, even if the push handle 15 can pass through the flange 9, and the push handle 15 can be placed on one side of the supporting plate 8.

[0051] The left side of the frame 1 has an inlet for receiving the transported printed matter, that is, the printed matter can enter the support plate 8 in the cutting device from the left side of the frame 1. The right side of the frame 1 is provided with a positioning member for positioning the position of the printed matter. The position of the printed matter to be cut is positioned by the positioning member, so that the cutting assembly determines the cutting position of the printed matter. The positioning member in this embodiment includes a positioning cylinder 7 and a push plate 12. The telescopic axis of the positioning cylinder 7 extends in the left and right directions. The push plate 12 is installed on the telescopic axis of the positioning cylinder 7. The push plate 12 is used to stop the printed matter to locate the cutting position of the printed matter. By adjusting the telescopic degree of the positioning cylinder 7, the positioning position of the printed matter is adjusted, that is, different positions of the printed matter are placed at the interval 16 of the two support plates 8, so that the cutting positions of the same type of printed matter are different, or it is used to cut printed matters of different sizes. Because the entire device is arranged at an angle, the flange 9 can position one side of the printed product, and the positioning member can position the other side of the printed product. The two sides are perpendicular to each other. By positioning the flange 9 and the positioning member, the printed product can be straightened to ensure that a qualified printed product can be obtained.

[0052] Specifically, the cutting assembly includes a top-pressing cylinder 4, a mounting plate 5, a cutter 6 and a pressing plate 11. The top-pressing cylinder 4 is mounted on the frame 1, and the telescopic shaft of the top-pressing cylinder 4 extends in the up-down direction. The mounting plate 5 is slidably mounted on the frame 1, and the mounting plate 5 is located above the supporting plate 8. The telescopic shaft of the top-pressing cylinder 4 is connected to the mounting plate 5, and the mounting plate 5 can slide in the up-down direction by the driving of the top-pressing cylinder 4. The cutter 6 is fixedly mounted on the mounting plate 5, and the cutter 6 extends in the front-back direction, and the cutter 6 is directly opposite to the interval 16 between the two supporting plates 8. There are two pressing plates 11, and the two pressing plates 11 are disposed on the left and right sides of the cutter 6, and are used to press the printed matter. Each pressing plate 11 is connected to the mounting plate 5 through an elastic guide column 10. The printed matter is pressed by the pressing plate 11 to prevent the printed matter from being offset during cutting, which affects the cutting quality of the printed matter. The structure of the elastic guide column 10 in this embodiment can be the structure of the elastic connector described in the Chinese patent document with the authorization announcement number CN219542101U.

[0053] The cutter 6 has a cutting edge, and the cutting edge is arranged at an angle. In order to quickly complete the cutting action, reduce the stuck of the printed product, increase the stability of the cutting, not form burrs on the printed product, improve the quality of the finished product, and protect the cutter 6 and the equipment at the same time, the cutting edge can be arranged from front to back to face upwards, or from back to front to face upwards. Either inclination is feasible. In this embodiment, the inclination direction of the cutting edge is from back to front to face upwards.

[0054] Each pressing plate 11 has a tilted plate section and a flat plate section connected together, the tilted plate section is located on the left side of the flat plate section, and tilted upward. The tilted plate section of the pressing plate 11 faces the direction in which the printed matter is conveyed, and the tilting of the pressing plate 11 can prevent the printed matter from being affected by the pressing plate 11 and unable to be placed normally on the supporting plate 8.

[0055] The positioning cylinder 7 and the pressing cylinder 4 in this embodiment may also be replaced by an electric push rod or a hydraulic cylinder or other components capable of achieving linear movement.

[0056] By setting up the pneumatic slide 2, the pusher 15 can move in the avoidance hole 13 under the action of the pneumatic slide 2, so that the pusher 15 pushes the cut printed matter to move, and sends the printed matter out of the supporting plate 8, avoiding the use of manual handling of the cut printed matter and improving production efficiency. At the same time, the cutting device can be linked with the front-end process and the back-end process by adding a transfer device, thereby improving the degree of integration and automation, and realizing automatic transportation of printed matter.

[0057] The working process of this utility model is as follows:

[0058] The printed matter is transported to the support plate 8 by a conveying device to wait for cutting by the cutting assembly. At this time, the flange 9 positions one side of the printed matter, and the positioning member positions the other side of the printed matter. The two sides are perpendicular to each other. The printed matter is corrected by positioning the flange 9 and the positioning member. The cutter 6 is pressed down, and the pressing plate 11 first contacts the printed matter, thereby pressing the printed matter to prevent it from shifting during cutting. Then, the cutter 6 facing the gap cuts the printed matter, cutting one printed matter into two printed matters. Then, the two pneumatic slides 2 push the pushers 15 to push the printed matters placed on the two support plates 8 onto the placement table 3, thereby completing the cutting of the printed matter.
