Description

Technical Field

[0001] The invention relates to the technical field of tobacco belt dust removal equipment, in particular to a belt dust removal device for tobacco production. Background Art

[0002] During the production process of cigarettes, cigarettes need to be transported by conveyor belts. The cigarette group conveyor belt is located below the cigarette drop channel. After the machine is started normally, the tobacco and smoke at the ends of the cigarettes fall directly and indirectly on the conveyor belt. After being transmitted by the conveyor belt, they are stuck in the teeth and pulleys of the conveyor belt and go up and down. Long-term accumulation fills up the roots of the tooth grooves and the belt grooves, causing the belt to slip and damage during the conveying process, making the equipment unable to operate normally. Normally replacing the belt and dust reduction maintenance also requires a long time and manpower.

[0003] When workers clean the tobacco accumulated on the existing conveyor belt, they need to disassemble the conveyor belt and then clean the tobacco accumulated inside it. Therefore, this method brings great work intensity to the workers, and the conveyor belt can only be cleaned regularly, so the cleaning efficiency is low. Summary of the invention

[0004] The object of the present invention is to provide a belt dust removal device for tobacco production to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0011] As a further solution of the present invention: an annular groove is opened on the side wall of the support plate, and a first slider is fixedly connected to the side wall of the conveyor belt. The first slider is slidably connected in the annular groove. The conveyor belt is made of soft material. The arrangement of the first slider and the annular groove facilitates the sliding of the conveyor belt on the side wall of the support plate.

[0012] As a further solution of the present invention: a fixing plate is fixedly connected to the outer side wall of the suction hood, and the fixing plate is fixedly connected to the side wall of the support plate by locking bolts.

[0020] The left and right outer walls of the shell are provided with sliding grooves, and a second slider is slidably connected in the sliding grooves. The lower end surface of the second slider is fixedly connected to a support plate, and the second slider is fixedly connected in the sliding grooves by screws. When the tobacco in the charging box is discharged to the outside of the shell, the staff manually turns the screw to make one end of the screw detach from the shell and the side wall of the second slider. The staff manually pushes the second slider downward to move the support plate downward. The staff rotates the screw in the opposite direction to fix the support plate, and the support of the shell is achieved through the support plate.

[0021] As a further solution of the present invention: the end of the charging box is fixedly connected with a rotating shaft, one end of the rotating shaft is rotatably connected to the side wall of the second filter plate, and the charging box is easily rotated in the housing through the rotating shaft;

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] First, the detachable connection between the support plates facilitates the disassembly of the support plates by the staff, thereby facilitating the disassembly of the suction cover inside the support plates. When the suction cover is removed from the support plates, it is convenient for the staff to clean the residual tobacco on the suction cover.

[0026] 2. By arranging a first filter plate at the opening of the suction hood, the end of the first filter plate is fixedly connected with a turntable, and the turntable is rotatably connected to the side wall of the opening of the suction hood. When the suction hood is removed from the support plate and the first filter plate needs to be cleaned, the staff manually pulls the pull plate, and the pull plate drives the movement of the locking rod. When one end of the locking rod is separated from the turntable, the staff manually rotates the first filter plate to adjust the first filter plate to a position convenient for cleaning; when the first filter plate is adjusted to a suitable position, the staff manually releases the pull plate, and due to the action of the spring, one end of the locking rod passes through the side wall of the suction hood and is inserted on the turntable. The position of the first filter plate is fixed by the locking rod, which is convenient for the staff to clean.

[0027] 3. The suction hood is connected with a suction pipe, one end of which passes through the side wall of one of the support plates and is connected with a suction device. The suction fan works to make the tobacco on the conveyor belt be sucked into the charging box from the suction pipe, and the accumulated tobacco on the conveyor belt is collected through the charging box in the shell.
