The present disclosure relates to the field of plant trimmers, in particular to a cutting device with a blade moving in parallel, a moving method and a plant trimmer
In equipment for trimming flower buds, branches and leaves, a blade often needs to be removed for cleaning, and then are mounted back into the equipment. During assembling, it is necessary to ensure that a round blade is parallel to a cutting mesh, and to adjust a space between the round blade and the cutting mesh in real time according to a length of a residual leaf that needs to be reserved for a flower bud. In the existing equipment for trimming flower buds, branches and leaves, a plurality of screws are often combined to perform adjustment, which easily causes inconsistency in adjustment heights of the plurality of screws and leads to a problem of tilting of the round blade.

The present disclosure has the beneficial effects below: By the structural design, the rotating signal of the adjustment knob is transmitted to the adjustment portion through the flexible shaft, so as to drive the adjustment portion to push the movable plates to horizontally move. The round blade can be adjusted to be kept in vertical rising and dropping, and is always kept in parallel to the cutting mesh. By an adjustment knob, an adjustment screw is driven to rotate by a flexible shaft, so that the movable blade holder moves up and down, which completes the adjustment of the round blade in a visible region of the equipment. The automatic blade adjustment structure is simple. After the cleaning of the round blade is completed at each time, only simple screw locking is required, which can easily adjust the space between the round blade and the cutting mesh, without worrying about the parallelism.
The plant to be trimmed is stripped using the rotation of the agitation fingers. Since a fan is arranged in the cutting device, the negative pressure is generated in the barrel body due to adjustment of an air intake adjustment port. Thus, it is convenient for the waste to pass through the cutting mesh for cutting and collection. The material is rotated to be attached on the inner wall of the barrel body under the rotation of the agitation fingers, and is thrown into the material collection tank for collection under the action of the centrifugal force. Thus, the waste and the material are stripped for separate collection.

Further, as shown in
During working, when the cutting motor 75 drives the motor rotating shaft 751 to rotate after being powered on, the motor rotating shaft rotates to drive the movable blade holder 710 to rotate, so that the fan vanes and the round blade rotate together with the movable blade holder to perform cutting. When the position of the round blade in the vertical direction needs to be adjusted, the adjustment knob 732 is rotated. A rotating signal is transmitted to the adjustment portion 734 through the flexible shaft 731. The adjustment portion rotates in the adjustment device guide slot 763 to push the movable plates to horizontally move. Since the movable plates horizontally move, a certain point on the inclined guide slot 761 moves relatively in both the horizontal direction and the vertical direction. Under the action of the step pins 772, the bearing pedestal moves in the guide slots relatively in the horizontal direction and the vertical direction. The bearing pedestal is arranged on the guide pins 791 and cannot move in the horizontal direction. Therefore, the bearing pedestal 77 can only move in the vertical direction. Thus, the movable plates move horizontally, and the bearing pedestal only moves in the vertical direction. When the bearing pedestal moves in the vertical direction, the bearing pedestal drives the movable blade holder 710 to move only in the vertical direction, so that the round blade 71 moves in parallel in the vertical direction.
A moving method of a cutting device with a blade moving in parallel according to a preferred embodiment of the present disclosure includes the following steps:
Step 1: the adjustment knob is rotated to transmit a rotating signal to the adjustment portion through the flexible shaft.
Step 2: the adjustment portion pushes the movable plates to horizontally move.
Step 3: the movable plates horizontally move to adjust the movement of the bearing pedestal in the vertical direction.
Step 4: the movement of the bearing pedestal in the vertical direction drives the round blade to move in parallel in the vertical direction.

During use, a cover plate 21 for feeding is opened to add a material to be trimmed to the barrel body 3. The agitation motor 61 drives the agitation fingers 62 to rotate to trim and strip the material to be trimmed Under the action of the agitation fingers, the qualified material is stripped from the waste. The negative pressure is generated in the barrel body due to the gravity of the waste and the fan vanes 72, so that the waste is chopped by the round blade 71 after passing through the cutting mesh 32, and then enters the waste collection tank. Since the radius of the qualified material is larger than an aperture of the cutting mesh, lots of qualified materials are accumulated at the top of the cutting mesh. As the agitation fingers rotate, the qualified materials are attached to the inner wall of the barrel body under the action of the centrifugal force in the rotating process, and rotate with the agitation fingers. After the baffle plate 4 is pulled away, the qualified materials on the inner wall of the barrel body are discharged from the material outlet 31 in the rotating process, and enter the material collection tank 5. The collection progress of the material collection tank can be observed through the observation window 51. When the air flow and the negative pressure in the barrel body need to be adjusted, the air intake adjustment plate 20 is opened to let air enter the barrel body, thereby adjusting the negative pressure in the barrel body. When the distance between the round blade and the cutting mesh needs to be adjusted, a reference will be made to the description of the foregoing parallel movement of the cutting device, and repeated descriptions will not be made here.
