[0033] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0034] According to the utility model, if Figure 1 and Figure 2As shown, a tobacco shred slicer is provided, including: a guard plate 1 with a U-shaped structure, installed on an equipment bracket 6, which protects the internal equipment of the slicer, and a rectangular opening is provided at the upper end of the guard plate 1 for the cutter to pass through when it moves up and down; a shaft 2 is located above the guard plate 1, including an internal rotating shaft and an external fixed shaft, the internal rotating shaft is mechanically connected to a motor reducer 12, and drives it to run when the motor runs, and the external fixed shaft is mechanically connected to the cutter 9 and is fastened with bolts; a first roller 3 is installed inside the guard plate and fastened with bolts for the safety rope 4 to slide; one end of the safety rope 4 is fastened to a screw rod 7, one end of which is a fixed part, the middle of the safety rope 4 passes through the first roller 3 and the second roller 8, and the other end is fastened to a limit switch 5 This part is the movable part; the limit switch 5 is installed inside the guard plate 1 and is bolted, and the movable rod of the limit switch 5 is connected to one end of the safety rope 4; the bracket 6 stands on the ground to support the entire slicer; the screw 7 is fixed inside the guard plate 1 and is tightly connected to one end of the safety rope 4, which is used to fix one end of the safety rope 4; the second roller 8 is installed inside the guard plate and is bolted for the safety rope 4 to slide; the cutter 9 is driven up and down by the shaft 2; one end of the hinge 10 is fixed to the side box frame of the slicer, and the other end is fixed to the edge of the side door 11, one on the upper and lower sides, which is used to open and close the side door 11; the side door 11 is connected to the side box of the slicer through the hinge 10, which plays a role in the equipment inside the side box of the slicer. Safety protection function; the motor reducer 12 is installed on the upper and lower movable platform, the load end of the reducer is connected to the shaft 2, and the operation of the motor reducer 12 drives the shaft 2 to run; the gear 13 is installed on the shaft 2, located between the motor reducer 12 and the cutter 9 connecting shaft, the operation of the shaft 2 drives the gear 13 to run, and the motor reducer and its platform are driven up and down by the chain 14, thereby driving the cutter to run up and down; the chain 14 is fixed on the fixed seat 17, and the motor reducer 12 and its platform are driven to run up and down by the operation of the gear 13; the door handle 15 is installed on the side door 11, and is used to open and close the side door 11; the first proximity switch 16 is installed on the inner guard plate of the side box of the slicer, and its detection part is in contact with the opening and closing edge of the side door 11 The sensing piece 20 is installed below the movable platform of the motor reducer 12, and the motor reducer 12 drives it to move up and down. The second and third proximity switches 18 and 19 are sensed by the sensing piece 20, and the upper and lower running positions of the motor reducer 12 are controlled, thereby controlling the upper and lower running positions of the cutter 9.

[0035] Specific working principle: limit switches and proximity switches are connected to the PLC system, and the slicer motor reducer servo drive is connected to the PLC system.

[0036] When the slicer is not working, the cutter 9 is in the lifting state and stops at the third proximity switch 19 at the upper limit. When working, when a cigarette pack is detected under the cutter, the PLC system controls the motor reducer 12 to run downward, and the cutter slices the cigarette pack. When the induction plate runs to the second proximity switch 18, the motor reducer stops running and the cutter stops at the lowest point. At this time, the cutter just cuts the cigarette pack; at the same time, when the second proximity switch 18 detects a signal, the PLC system controls the motor reducer to run in the reverse direction and controls the cutter to lift the cutter. When the induction plate runs to the third proximity switch 19, the motor reducer stops running, and the process of cutting a cigarette pack is completed.

[0037] One end of the safety rope 4 inside the slicer is connected to the rotating part of the limit switch 5, and the limit switch 5 is connected to the equipment emergency stop system. The other end is fixed on the screw 7. When relevant personnel enter the slicer to handle faults or clean and maintain, in an emergency, they can pull the safety rope 4 to any position to drive the rotating part of the limit switch 5 to rotate, disconnect the equipment emergency stop system, and cut off the power of the slicer's electronic control system, which plays a good protective role in dealing with unexpected situations.

[0038] There are motor reducers 12, lifting platforms and induction plates 20 running up and down in the side box of the slicer. When relevant personnel enter the inside to handle faults or clean and maintain, there is a possibility of moving parts running, which poses a safety hazard of injuring people. A first proximity switch 16 is added at the position of the switch of the inner door 11 of the side box of the slicer. The first proximity switch 16 is connected to the PLC system. When the side door 11 is closed, the first proximity switch 16 is sensed, and the system detects that the side door 11 is in a closed state, and the slicer works normally; when the side door 11 is opened, the first proximity switch 16 is not sensed, and the system believes that the side door 11 is in an open state. At this time, the entire slicer is in a paused state. When the door is closed, the system resumes normal operation. Because relevant personnel need to open the side door 11 before entering the side box to handle faults or clean and maintain, adding the first proximity switch 16 for detection at the position of the switch of the inner door 11 of the side box of the slicer plays a good protective role.

[0039] In summary, the technical content disclosed by the utility model can cut off the power of the slicer machine through a safety rope when relevant personnel enter the interior and encounter an emergency, and when the side door is opened, the slicer cutter temporarily stops running, etc., which improves the intelligence level of the equipment and increases the safety of equipment use.

[0040] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
