Description

Technical Field

[0001] The utility model relates to the technical field of tobacco cutters, and more specifically, to a metal automatic removal device for a cutter. Background Art

[0002] Due to the high-speed rotation of the cutter roller of the cutter, in order to prevent the cutter from cutting metal impurities during operation and damaging the equipment, a metal removal device is installed before the cutter feeds materials. The device mainly consists of a metal detector, a cylinder, a connecting rod and a flap. When the metal detector detects that the conveyed materials contain metal debris, after appropriate delay, at the moment when the materials pass through the flap, the solenoid valve acts to retract the cylinder rod, driving the connecting rod to open the valve, and the materials containing metal fall through the debris channel. After an appropriate time, the cylinder drives the flap to return to its original position.

[0003] During the delay time when the flap valve is open, the materials containing metal impurities are uniformly collected into the collection box. It is necessary to manually screen the metal impurities and then re-mix the materials. Some metal impurities are small and sometimes cannot be found manually. The metal impurities in the re-mixed materials pass through the debris channel again and are screened again, which brings a lot of difficulties to the sorting work, is time-consuming and laborious, and also causes waste of tobacco leaves.

[0025] As Figure 1 shown, an embodiment of the present utility model provides a metal automatic removal device for a wire cutting machine, including: a material conveying vibrating trough 1, a first metal sensor 2, a removal assembly 3, and a control assembly.

[0026] The material conveying vibrating trough 1 is fixed on the frame of the wire cutting machine.

The second metal sensor 34 is arranged above the feeding opening 11.

[0028] Specifically, both the second metal sensor 34 and the first metal sensor 2 are connected to the control assembly.

[0029] During use, when the first metal detector detects that there is metal in the cut tobacco and transmits the detection signal to the control assembly, the control assembly controls the movable flap 12 to open, and then opens the feeding opening 11, so that the cut tobacco with metal in the material conveying vibrating trough 1 enters the wire inlet and enters the connecting pipe 31.

[0030] When the second metal detector detects that there is metal in the cut tobacco, the second metal detector transmits the detection signal to the control assembly. The control assembly controls the purging pipe to open and introduce air into the connecting pipe 31, and then blows the cut tobacco with metal into the metal discharge channel 32, thereby accurately removing the metal in the cut tobacco.

[0031] In the present utility model, the movable flap 12 is rotatably arranged on the feeding port 11. The first metal sensor 2 is arranged at the wire inlet of the material conveying vibrating trough 1.

The control component controls the movable flap 12 to open, so that the cut tobacco with metal enters the connecting pipe 31 from the feeding port 11. When the second metal detector detects that there is metal in the cut tobacco, the second metal detector transmits the detection signal to the control component. The control component controls the purging pipe to open and introduce air into the connecting pipe 31, and then blows the cut tobacco with metal into the metal export channel 32, thereby completing the accurate rejection of the metal in the cut tobacco, reducing the labor intensity of the operator, and improving the efficiency of metal screening and rejection.

[0034] When the first metal detector detects that there is metal in the cut tobacco and transmits the detection signal to the control component, the control component controls the movable flap 12 to open and controls the first cylinder 35 to start. The first cylinder 35 starts to drive the blanking flap 36 to rotate, thereby conducting the connecting pipe 31 to enable the cut tobacco to continue to fall.

[0035] In the present utility model, by arranging the blanking flap 36 inside the connecting pipe 31 and close to the first end of the connecting pipe 31, and connecting the first cylinder 35 to the blanking flap 36, a buffering effect is exerted on the falling process of the cut tobacco, avoiding the problem that the falling speed of the cut tobacco with metal is too fast, resulting in poor metal rejection efficiency.

The second cylinder 4 drives the connecting rod to move, and the connecting rod drives the movable flap 12 to move, thereby opening the feeding port 11, so that the cut tobacco with metal drops from the feeding port 11 into the connecting pipe 31.

[0048] At this time, the controller controls the first cylinder 35 to start. The first cylinder 35 starts to drive the blanking flap 36 to rotate, thereby opening the connecting pipe 31 to enable the cut tobacco to continue to fall.

[0049] When the photoelectric switch 39 continuously detects the material falling into the connecting pipe 31, the first cylinder 35 continuously maintains the working state. When the photoelectric switch 39 detects that there is no material falling into the connecting pipe 31, the photoelectric switch 39 transmits the detection signal to the controller, and the controller controls the first cylinder 35 to close, so as to be able to close the connecting pipe 31 with the blanking flap 36.

[0050] When the second metal detector detects that there is metal in the cut tobacco, the second metal detector transmits the detection signal to the controller, and the controller controls the purge solenoid valve 33 to open, so that the purge pipe is opened to introduce air into the connecting pipe 31, and then the cut tobacco with metal is blown into the metal export channel 32, thus completing the precise removal of the metal in the cut tobacco.
