Below in conjunction with embodiment the utility model is described further.

Please refer to Figures 1-3, the utility model provides a cutting structure of a high-speed paper cutter, including a base 1, the base 1 is used to support and fix the paper cutter and its components, and the top of the base 1 is provided with a cutting mechanism 2, Auxiliary fixing mechanisms 3 are provided on the front and rear sides of the top of the base 1;

The cutting mechanism 2 includes a support plate 4, the support plate 4 is respectively fixed on the left and right sides of the middle part of the top wall of the base 1, and a top plate 5 is fixed on the upper side between the two sets of support plates 4, and the support plate 4 plays the role of supporting and fixing the top plate 5. The middle part of the top plate 5 bottom wall is fixed with a hydraulic cylinder 6, and the output end of the hydraulic cylinder 6 is fixed with a mounting plate 8. When the hydraulic cylinder 6 works, the output end moves up and down to drive the mounting plate 8 to move up and down. Slot 9, the inner side of chute 9 is slidably connected with cutting knife 10, and cutting knife 10 can move left and right on the inner side of chute 9, and the left and right sides of the front and rear side walls of cutting knife 10 are all provided with limiting grooves 11, and the inner sides of limiting groove 11 are all slidably connected There is a toggle lever 13, and the end of the toggle lever 13 away from the cutter 10 is fixed with a fixed block 12, the fixed block 12 can fix the toggle lever 13, and the toggle lever 13 can limit the movement track of the cutter 10, Make it move horizontally in reverse while moving down.

Further as shown in Fig. 1, Fig. 2 and Fig. 3, it is worth explaining in detail that the auxiliary fixing mechanism 3 includes a lower pressing plate 16, and the left and right sides of the bottom wall of the lower pressing plate 16 are fixed with lower pressing rods 15, and the lower pressing rods 15 are all fixed to each other. Through and slidingly connected to the inner side of the through hole 17, the through holes 17 are respectively arranged on the left and right sides of the top wall of the base 1, the front and rear sides, and the lower pressing plate 16 can move down under the pull of the lower pressing rod 15 to cut the cut objects on the top of the base 1. It is clamped and fixed to facilitate subsequent cutting operations.

Further as shown in Figure 3, it is worth specifying that the fixed block 12 is fixed on the bottom of the connecting rod 7, and the connecting rod 7 is respectively fixed on the front, rear, left and right sides of the bottom wall of the top plate 5, and the connecting rod 7 is used to align the fixed block. 12 to install and fix.

This scheme has the following working process: when it is necessary to use a paper cutter to cut paper, first put the material to be cut into the lower sides of the two sets of lower platens 16, then start the cylinder 19, and the output end of the cylinder 19 is extended to make the connecting plate 18 moves downward, and the connecting plate 18 drives the lower pressing rod 15 and the lower pressing plate 16 to move downward to clamp and fix the object to be cut, and then starts the hydraulic cylinder 6, and the output end of the hydraulic cylinder 6 is extended to make the mounting plate 8 and the The cutting knife 10 moves downward, and during the downward movement of the cutting knife 10, it moves in the horizontal direction under the action of the limit groove 11 and the toggle lever 13, so that the cutting knife 10 is pressed down and moved in the process of cutting the object to be cut. Sliding reduces the resistance that the cutting knife 10 is subjected to, and completes the cutting operation of the paper cutter.

According to the above working process, it can be seen that the output end of the hydraulic cylinder 6 is extended during the working process, thereby driving the mounting plate 8 and the lower side cutter 10 to move downward. Restricted by the toggle lever 13, and the toggle lever 13 is fixed, so the cutting knife 10 will move along the track of the limit groove 11 to realize pulling and cutting of the lower side paper articles, which is different from the traditional vertical downward cutting. Compared with the paper machine, the resistance of the cutting structure is reduced, thereby reducing the working difficulty of the paper cutting machine and improving the working efficiency of the paper cutting machine. Before the object is cut, the output end of the cylinder 19 can be stretched. Under the reaction force, the lower pressing rod 15 and the lower pressing plate 16 are moved down, and the lower side of the object to be cut is pressed and fixed, so that the cutting work of the paper cutter will be smoother, the manual operation will be saved, and the working time of the paper cutter will be reduced.

During the downward movement, it can be inserted into the inner opening 14 of the mounting plate 8 to prevent the fixing block 12 from obstructing the mounting plate 8 .

As further shown in FIG. 1 , it is worth mentioning that the cutting knife 10 is located on the upper side between two sets of lower pressing plates 16 , and the cutting knife 10 can cut objects between the lower pressing plates 16 driven by the hydraulic cylinder 6 .

To sum up: the lower pressing rod 15 plays the role of connecting the lower pressing plate 16 and the connecting plate 18, so that the downward movement of the connecting plate 18 can drive the lower pressing plate 16 to move synchronously and then press and fix the cut object, and the opening 14 is set to make the fixing block 12. During the downward movement of the cutting knife 10, it can be inserted into the opening 14 of the mounting plate 8 to prevent the fixed block 12 from hindering the mounting plate 8. The cutting knife 10 can be driven by the hydraulic cylinder 6 to carry out the work on the objects between the lower pressing plates 16. Cutting, during the downward movement of the cutting knife 10, because the limit groove 11 provided on the surface of the cutting knife 10 is restricted by the toggle lever 13, and the toggle lever 13 is fixed, so the cutter 10 will follow the track of the limit groove 11 And move, realize pulling and cutting lower side papery article.

The hydraulic cylinder 6 can be purchased from the market, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the description.
