Description

Technical Field

[0001] The utility model relates to tobacco leaf screening equipment, and more specifically, to a pull-out type vibrating groove screen for tobacco. Background Art

[0002] Vibrating conveyors are widely used in the tobacco industry. When the vibrating conveyor is working, the motor pulley drives the eccentric shaft to rotate through the V-belt, thereby generating a periodic exciting force, which is transmitted to the balance frame by the connecting rod and the vibration reduction mechanism, and then to the trough body by the rocker arm, forcing the trough body to perform approximate simple harmonic vibrations in a certain direction. The material is then continuously thrown or slid in the transportation direction in the trough body, thereby moving the material forward and achieving the purpose of conveying. By installing appropriate vibrating trough screens in the trough body of the vibrating conveyor, a screening effect can be achieved, so that materials such as tobacco shreds and tobacco leaves can pass through the screen for screening normally and enter the next process; while fine particles such as smoke dust and smoke residue fall into the trough body after being screened by the screen and are centrally processed by the dust removal negative pressure system. The screen can generally have one or two layers of screens, and multiple layers can be set when special needs arise. There are two main types of connection between the screen and the trough body:

[0003] 1. Fixed type - directly connected to the tank body with rivets;

[0004] 2. Movable type - fixedly connected to the tank body with screws;

[0005] After long-term use, vibrating conveyors require maintenance of the trough. This involves removing the screen to clean tobacco residue from the trough surface beneath it and prevent the infestation of the trough. However, the numerous screws connecting the screen to the trough make disassembly complex, and after removal, multiple people are required to lift the screen out of the trough, which is labor-intensive.

[0006] CN115518874A discloses a screen that uses a 4*4 woven mesh vibrating groove screen compared to the mesh size of a traditional screen to facilitate screening and recovering long tobacco in a residual smoke mixture. This solution only solves the problem of tobacco recovery by improving the mesh size of the screen, and its disassembly and maintenance are relatively complicated.

[0007] CN210538860U discloses a switching device for a wire feeding vibration trough screen, which uses a hinge to connect a thin plate and a screen, and is equipped with a magnet to facilitate the fixing of the thin plate. When it is necessary to screen out cigarette dust, the thin plate is in an open state, and when it is not necessary to screen out, the thin plate is in a closed state to cover the screen. Although the device switches states quickly and easily, it is inconvenient to clean the vibration trough because the screen is fixedly installed in the vibration trough, and the thin plate is fixed to the screen by a magnet. When the vibration trough vibrates, the thin plate is easily vibrated open, resulting in an unstable state of the thin plate. Utility Model Content

[0008] The utility model overcomes the shortcomings of the prior art and provides an implementation method of a pull-out type vibrating trough screen for cigarettes, in the hope of solving the problem that the vibrating trough screen for cigarettes needs to be disassembled as a whole when cleaning and maintaining the existing vibrating trough, and the disassembly process is relatively complicated.

[0009] In order to solve the above technical problems, one embodiment of the present invention adopts the following technical solutions:

[0010] A pull-out vibrating trough screen for cigarettes comprises a screen and a screen frame. The screen is in the shape of a rectangular plate with a plurality of sieve holes distributed in a matrix on its upper portion. The screen frame is a hollow frame with a screen inlet on one side. The length of the screen inlet matches the length of the screen and the width matches the thickness of the screen. The screen is slidably installed in the screen frame from the screen inlet, and the screen frame is horizontally fixedly installed on the upper portion of the vibrating trough.

[0011] Furthermore, the mesh holes on the sieve are 4*4mm mesh holes.

[0012] Furthermore, a handle is provided on one side of the screen.

[0013] Furthermore, slide rails are provided on both sides of the screen inlet on the screen frame, and the slide rails are arranged along the pulling direction of the screen. The two ends of the screen are slidably installed in the screen frame through the slide rails.

[0014] Furthermore, locking devices for locking and limiting the screen are fixedly installed on both sides of the screen inlet on the screen frame.

[0015] Furthermore, the locking device includes a locking buckle and a locking hook, the locking buckle is fixedly installed on one side of the screen frame, and the locking hook is fixedly installed on one side of the screen.

[0016] Furthermore, screens are installed on both sides of the screen frame, and the screens on both sides are arranged opposite to each other. A plurality of screen frames are continuously installed on the upper part of the vibration trough.

[0017] Compared with the existing technology, the utility model has at least the following beneficial effects: the utility model can quickly move the screen out of the vibration trough through the pull-out screen, and the operator can quickly restore the screen after cleaning the vibration trough, thereby improving the efficiency of cleaning and maintenance of the vibration trough and reducing labor intensity during work.
