[0037] Please also read Figures 1 to 6 Now, a scissor-type waste cutting device provided in an embodiment of the present application is described. The scissor-type waste cutting device includes a wall panel 101, a shearing assembly and a driving mechanism. Among them:

[0038] The shearing assembly includes a fixed knife 201 fixedly connected to the wallboard 101 and a movable knife 202 movably connected to the wallboard 101. The end of the movable knife 202 forms an extension portion 203 that always slides against the fixed knife 201. The extension portion 203 is used to extend the surface that abuts against the fixed knife 201 and then pass through the blade of the movable knife 202. The fixed knife 201 is used to extend the surface that abuts against the extension portion 203 and then pass through the blade of the fixed knife 201. The driving mechanism is transmission-connected to the movable knife 202 and is used to drive the movable knife 202 to move relative to the fixed knife 201.

[0039] According to the above structure provided in the present embodiment, in the scissor-type waste cutting device provided in the present embodiment, the end of the movable knife 202 forms an extension portion 203 that always slides against the fixed knife 201. Since the surface of the extension portion 203 that is used to abut against the fixed knife 201 extends through the blade of the movable knife 202 and the surface of the fixed knife 201 that is used to abut against the extension portion 203 extends through the blade of the fixed knife 201, the extension portion 203 and the fixed knife 201 that abut against each other form a scissor-type structure, which can not only make the blade of the movable knife 202 stably approach or move away from the blade of the fixed knife 201, but also make the movable knife 202 and the fixed knife 201 have a sliding contact matching state without matching gap when they cooperate to shear materials, which is very beneficial to the shearing of waste materials and can provide stability far superior to the prior art.

[0040] In another embodiment of the present application, please refer to Figures 1 to 6The driving mechanism includes a moving seat 301 for mounting the moving knife 202 and a guide block 302 connected to the moving seat 301. The guide block 302 forms a slide groove 303 extending along the moving direction of the moving knife 202. The driving mechanism also includes a roller 304 that is rollingly connected to the side wall of the slide groove 303. In this embodiment, the scissor-type waste cutting device also includes a first top plate 102 horizontally connected to the wall plate 101 and an adjustment seat 103 hinged on the wall plate 101. The roller 304 is also hinged on the adjustment seat 103 and forms a parallel rotation center axis with the adjustment seat 103. A tension spring 104 is also connected between the adjustment seat 103 and the first top plate 102 to make the adjustment seat 103 form a rotation tendency. The roller 304 forms a tendency to approach the fixed knife 201 under the rotation tendency of the adjustment seat 103.

[0041] According to the above structure provided in the present embodiment, since the tension spring 104 connected between the first top plate 102 and the adjustment seat 103 can make the adjustment seat 103 continuously have a tendency to rotate, and under this rotation tendency, the roller 304 hinged on the adjustment seat 103 has a tendency to rotate close to the fixed knife 201, so the roller 304 rollingly connected in the slide groove 303 can, on the one hand, smoothly roll in the slide groove 303 during the process in which the movable seat 301 drives the movable knife 202 to move toward the fixed knife 201, and on the other hand, it can also drive the guide block 302 and the movable seat 301 to have a tendency to approach the fixed knife 201, so that the movable knife 202 and its extension part 203 connected to the movable seat 301 always slide and press against the cutting edge surface of the fixed knife 201 during the movement, ensuring that the cutting edges of the movable knife 202 and the fixed knife 201 are always in the best matching state, which is conducive to further improving the use stability of the scissors-type waste cutting device in the present embodiment.

Since at least a portion of the adjusting seat 103 protrudes onto the axial extension path of the adjusting handle 106, when the adjusting handle 106 moves relative to the support 105, not only can the distance between the adjusting handle 106 and the adjusting seat 103 be changed, but it can also be used to limit the rotation range of the adjusting seat 103 and adjust the pressing force between the extension part 203 and the fixed knife 201, which has a flexible adjustment effect.

[0043] In another embodiment of the present application, please refer to Figures 1 to 6The end of the tension spring 104 away from the adjustment seat 103 is connected to a pull rod 107, and the tension spring 104 is connected to the first top plate 102 through the pull rod 107. The upper end of the pull rod 107 that passes through the first top plate 102 is screwed with an adjustment nut 507 for adjusting the position of the pull rod 107 along its own axial direction. According to the above structure provided in this embodiment, the pull rod 107 can effectively reduce the length of the spring 314 and significantly reduce the manufacturing cost of the scissor-type waste cutting device in this embodiment. At the same time, the tension force of the tension spring 104 can be adjusted by adjusting the upper and lower positions of the pull rod 107, thereby adjusting the pressing force of the mating surface between the extension part 203 and the fixed knife 201.

An opening slot 310 for the moving seat 301 to pass through is provided on the wall panel 101. The moving seat 301 passes through the opening slot 310 and is connected to the pulling arm 309. According to the above structure provided in this embodiment, when the power end of the main cylinder 307 is extended or retracted, the moving seat 301 can be driven to move in the opening slot 310 through the pulling arm 309, which not only has a better driving effect, but also can further improve the moving stability of the moving seat 301.

[0046] In another embodiment of the present application, please refer to Figures 1 to 6The scissor-type waste cutting device also includes a traction mechanism and a conveyor belt 401 distributed on both sides of the shearing assembly. The traction mechanism includes a driving roller 501 and a pressure roller 502 arranged in parallel with each other, and also includes a swing seat 503 connected to both ends of the pressure roller 502 and hinged on the wall panel 101.

According to the above structure provided in this embodiment, the pressure roller 502 that can approach or move away from the driving roller 501 can be adapted to the thickness of different waste materials, which is conducive to significantly improving the feeding stability of the traction mechanism in this embodiment. In addition, the cut waste can be directly dropped onto the conveyor belt 401 and transported to the target position, which is conducive to further improving the waste cutting efficiency of the scissor-type waste cutting device in this embodiment.
