Therefore, they should not be understood as limitations on the present utility model.

[0041] In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more than two. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0042] like Figure 1-7 As shown, the utility model provides a cutting mechanism, which includes: a frame 1, the middle part of the frame 1 is horizontally provided with a carrier plate 101; a lower cutting assembly 2, including a carrier 201, a knife plate 204 and a lower cutting knife 203, a side surface of the carrier 201 is provided with a receiving cavity 202, the knife plate 204 is fixedly arranged on the side of the carrier 201, and the lower cutting knife 203 is arranged in the receiving cavity 202 and is fixedly connected with the knife plate 204; an upper cutting assembly 3, including a fixed plate 301 and an upper cutting knife 302 fixedly arranged on the side of the fixed plate 301; a driving cylinder 4, which is mounted on the top of the frame 1, and the driving cylinder 4 is used to drive the connected fixed plate 301 to drive the upper cutting knife 302 to reciprocate up and down relative to the lower cutting knife 203.

[0043] The utility model provides a cutting knife mechanism that drives the fixing plate 301 by driving the cylinder 4, thereby driving the upper cutting knife 302 to perform a close up and down offset reciprocating motion relative to the lower cutting knife 203 to achieve cutting of the edge material. Under the above structure, the upper cutting knife 302 and the fixing plate 301 are tightly locked by the screw, and the lower cutting knife 203 is tightly locked with the blade support plate 204 by the screw, and the lower cutting knife 203 is fixed in the accommodating cavity 202 by the blade support plate 204, so that the cutting knife mechanism will not loosen the upper and lower cutting knives 203 due to the vibration generated by itself during operation. At the same time, the setting of the guide rod 5 enables the upper cutting knife 302 to move up and down more stably, reducing the wear of the lower cutting knife 203; The cutting edge surface of the knife 203 is tightly connected to the inner side surface of the blade support plate 204. When the cutting edge surface of the lower cutter 203 is ground and then reinstalled on the blade support plate 204, the cutting edge surface of the lower cutter 203 is always in the same plane with the side surface of the carrier 201, that is to say, there is no need to adjust the gap between the lower cutter 203 and the upper cutter 302 when the cutting edge surface of the lower cutter 203 is reinstalled after grinding; the cutting edge surface of the upper cutter 302 can also be kept in the same plane with the side surface of the fixed plate 301 when it is reinstalled on the fixed plate 301 after grinding. Therefore, the cutting edges of the upper and lower cutters can be directly installed and used after grinding, and there is no need to perform tedious adjustment work on the gap between the upper and lower cutters, thereby improving production efficiency.

[0044] In this embodiment, if Figure 3As shown, the frame 1 includes a bottom plate arranged at the bottom, two vertical supporting upright plates are respectively arranged on both sides of the bottom plate, and a top plate in a horizontal plane is arranged at the top of the frame 1, and the two ends of the top plate are respectively fixedly connected to the tops of the two supporting upright plates; the carrier plate 101 is horizontally connected between the two supporting upright plates. On the one hand, the carrier plate 101 can enhance the stability of the entire frame 1, and on the other hand, it is used to carry and install the entire lower cutting assembly 2 and withstand the impact force brought by the cutting mechanism during cutting.

[0045] Further, such as Figure 4 and Figure 5 As shown, the carrier 201 is positioned on the carrier plate 101 by a plurality of pins, and the outer side surface of the carrier 201 and the outer side surface of the fixing plate 301 are arranged in the same plane up and down; a receiving cavity 202 matching the lower cutter 203 is opened in the middle of the outer side surface of the carrier 201, and when the lower cutter 203 is placed in the receiving cavity 202, the blade surface of the lower cutter 203 and the outer side surface of the carrier 201 are in the same plane, and four screw holes are respectively opened in an array at both ends of the outer side surface of the blade plate 204, and the blade plate 204 is respectively connected to the lower cutter 203 by screws. The cutter 203 and the outer side surface of the carrier 201 are threadedly fastened. This connection structure prevents the lower cutter 203 from loosening due to the vibration generated when the cutter mechanism is running, thereby avoiding the problem of the lower cutter 203 being worn due to looseness. At the same time, when the lower cutter 203 is re-ground and re-installed on the blade plate 204, the blade surface of the lower cutter 203 is always in the same plane with the outer side surface of the carrier 201, and there is no need to adjust the gap between the lower cutter 203 and the upper cutter 302, thereby improving work efficiency.

[0046] Specifically, a guide groove 241 is provided at the middle position of the knife plate 204, which is inclined outward. When the edge materials are chopped, they first fall on the guide groove 241 and are then transported to the collection box through the guide groove 241. The setting of the guide groove 241 makes it easier to uniformly collect the chopped edge materials, simplifies the subsequent collection work, and improves the efficiency of collecting debris.

[0047] In this embodiment, if Figure 1 and Figure 4As shown, an air avoidance hole 205 is respectively opened on the upper end surface of the carrier 201 on the left and right sides of the lower cutter 203, and a linear bearing is embedded in each of the two air avoidance holes 205. A sliding sleeve 501 is slidably provided in the two linear bearings. Two guide rods 5 are connected between the fixed plate 301 and the carrier 201. The upper ends of the two guide rods 5 are respectively fixed to the bottom surface of the fixed plate 301 on the left and right sides of the upper cutter 302, and the lower ends of the two guide rods 5 can be slidably extended into the sliding sleeve 501, so that the length range of the guide rod 5 extending into the sliding sleeve 501 is relatively large, which is convenient for the upper cutter. When the component 3 is pressed down, the guide rod 5 is provided with a sufficient avoidance stroke. The setting of the guide rod 5 enables the upper cutter 302 to move up and down more stably, reducing the wear of the upper and lower cutters 203; at the same time, a limit spring 502 is sleeved on the guide rod 5, one end of the limit spring 502 abuts against the bottom surface of the fixed plate 301, and the other end of the limit spring 502 abuts against the end of the upper end of the sliding sleeve 501. Therefore, when the guide rod 5 moves up and down, the sliding sleeve 501 will not be separated from the linear bearing due to the up and down movement of the guide rod 5, so that the guide rod 5 can slide tightly up and down on the sliding sleeve 501.

[0048] Further, such as Figure 6 and Figure 7 As shown, a connecting piece 6 is fixedly provided on the upper end surface of the fixed plate 301, and the top surface and one side surface of the connecting piece 6 are open structures. The upper ends of the left and right side surfaces of the connecting piece 6 are respectively protruded with shoulders 601 facing each other, and the driving cylinder 4 is installed on the top plate. The outer peripheral ring of the output end of the driving cylinder 4 is provided with a boss 401, and the boss 401 is located in the connecting piece 6, and the upper end surface of the boss 401 abuts against the bottom surface of the shoulder 601, and the lower end surface of the boss 401 abuts against the upper end surface of the fixed plate 301. The driving cylinder 4 drives the connecting piece 6 and the fixed plate 301 to drive the upper cutter 302 to perform a tight dislocation movement relative to the lower cutter 203 to achieve the cutting of the edge material; the setting of the connecting piece 6 can, on the one hand, play a connecting role between the driving cylinder 4 and the fixed plate 301, and on the other hand, it can facilitate the disassembly and assembly work between the driving cylinder 4 and the fixed plate 301, so that the structure of the cutter mechanism is simpler, the disassembly and assembly work of the cutter mechanism is reduced, and the work efficiency of manufacturing and later maintenance of the cutter mechanism is improved.

[0049] Specifically, Figure 6 As shown, the upper cutter 302 is threadedly locked and fixed to the outer side surface of the fixing plate 301 by multiple screws, so that the upper cutter 302 will not loosen due to the vibration generated when the cutter mechanism is running, thereby avoiding the problem of the upper cutter 302 loosening and causing the lower cutter 203 to wear. At the same time, when the upper cutter 302 is re-installed on the fixing plate 301 after grinding, the blade surface of the upper cutter 302 is always in the same plane with the outer side surface of the fixing plate 301, and there is no need to adjust the gap between the upper cutter 302 and the lower cutter 203, thereby improving work efficiency.
