Description

Technical Field

[0001] This utility model relates to a quick-change device for a flat belt of a dual-tube filter receiver, belonging to the technical field of filter transport device accessories in tobacco equipment. Background Technology

[0002] The YF24B.4IA dual-tube filter receiver, widely used in the tobacco industry, frequently experiences flat belt breakage due to its high operating time and speed. The initial design of the flat belt conveyor uses a self-tensioning structure without an independent tensioning mechanism, resulting in a fixed and non-adjustable shaft support spacing. Because the flat belt has limited elasticity, replacement requires forcibly stretching it to fit onto a drive shaft with a diameter larger than the trough surface. This operation easily leads to belt breakage, frequent replacements, and severely impacts equipment operating efficiency and maintenance costs. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a quick replacement device for the flat belt of a dual-tube filter receiver. The device sets the original drive shaft to a foldable state. When the drive shaft is folded, the flat belt can be installed smoothly. When the drive shaft is unfolded, the filter rod can be conveyed smoothly and can enter the hopper smoothly, thereby improving the equipment operating efficiency and maintenance costs.

[0004] To solve the above problems, the specific technical solution of this utility model is as follows: A quick replacement device for a flat belt of a dual-tube filter receiver includes a drive shaft, a movable bracket, a balance plate, a fixed bracket, and a driven shaft; the front and rear sides of the balance plate are respectively connected to the movable bracket and the fixed bracket by bolts; the outer ends of the two movable brackets support the drive shaft by bearings, and the outer ends of the two fixed brackets support the driven shaft by bearings; the drive shaft and the driven shaft have the same diameter, and grooves corresponding to the position of the flat belt are respectively provided on their circumferences; in the working state, the axes of the drive shaft and the driven shaft are located in the same plane; in the maintenance state, the movable bracket rotates to drive the drive shaft to rise, and the distance between the axes of the drive shaft and the driven shaft decreases.

[0005] The top surface of the balance plate is horizontal, and the bottom surface has a groove corresponding to the position of the flat belt. When the flat belt is running, it runs along the grooves on the top and bottom surfaces of the balance plate.

[0006] The balance plate has through guide grooves on its left and right sides and bottom; belt running grooves are equidistantly distributed around the circumference of the drive shaft and the driven shaft, and the positions of the belt running grooves and guide grooves are consistent with the projected position of the flat belt.

[0007] One end of the fixed bracket is connected to the balance plate by screws; the middle of the fixed bracket is provided with a limiting groove, which is inserted into an external fixing component; the fixed bracket positions the axis of the passive shaft by screws and the limiting groove.

[0008] One end of the movable bracket is connected to the balance plate by a screw; the middle part of the movable bracket is connected to the balance plate by a limit bolt; the movable bracket positions the axis of the drive shaft by the screw and the limit bolt; in the maintenance state, the limit bolt is loosened, and the movable bracket rotates around the screw.

[0009] The balance plate is located on one side of the movable bracket and has two connecting rods. These connecting rods pass around the drive shaft and connect to the dust collector plate. The inner end face of the dust collector plate is close to the flat belt on the drive shaft. The dual-tube filter receiver flat belt quick-change device of this application adopts the above structure and has the following advantages: 1. The balance plate of this application connects the passive shaft and the active shaft through a fixed bracket and a movable bracket respectively. By setting the included angle between the fixed bracket and the movable bracket, the axial distance between the passive shaft and the active shaft is shortened, which facilitates the disassembly and installation of the flat belt and improves maintenance efficiency. 2. The flat belt runs along the bottom guide groove and the grooves of the drive shaft and the driven shaft to prevent the flat belt from changing position when running at high speed and improve the running stability of the flat belt; 3. The fixed bracket uses a limiting groove for external positioning, which not only saves on connection structure but also provides good positioning effect; the movable bracket uses limiting bolts for positioning, which makes disassembly and assembly convenient and improves maintenance efficiency.
