Description

Technical Field

[0001] The utility model relates to the field of aluminum composite plate production equipment, in particular to an automatic screening device for raw materials for aluminum composite plate production. Background Art

[0002] In the production process of aluminum composite panels, it is necessary to screen the raw materials used in production to prevent larger particles or agglomerated materials in the powder from entering the silo. The utility model patent with application number 201620317701.2 discloses a production equipment for aluminum composite panels, which uses a screen to screen the powder, avoids the clogging of the powder in the silo, and reduces the adverse effects on the production of aluminum composite panels.

[0003] In order to improve the screening efficiency of powder materials, the screen can be vibrated or reciprocated horizontally, but it is unable to automatically clean the larger particles or agglomerated materials retained on the screen, and often requires shutdown for cleaning and maintenance, which reduces production efficiency and needs improvement. Utility Model Content

[0004] The utility model aims to provide an automatic screening device for raw materials in the production of aluminum composite panels, which can screen powder materials and automatically clean up larger particles and agglomerated materials.

[0005] To achieve this purpose, the utility model adopts the following technical solutions:

[0006] An automatic screening device for raw materials for producing aluminum composite panels comprises: a first hopper, a second hopper, a frame and an annular screen, wherein the first hopper is arranged at the bottom of the frame, two parallel and spaced synchronous belts are arranged in the frame, the annular screen is connected between the two synchronous belts and is located above the first hopper, the frame is provided with a material guide trough extending obliquely downward from the inner side of the annular screen, and the second hopper is arranged at the bottom of the material guide trough.

[0007] Wherein, a third hopper located above the annular screen is arranged on the frame.

[0008] Wherein, a synchronous wheel supporting the operation of the synchronous belt is arranged in the frame.

[0009] Wherein, a discharge valve is arranged at the bottom of the first hopper.

[0010] Wherein, a flow box is arranged below the discharge valve.

[0011] Wherein, a screw conveyor is arranged at the bottom of the second hopper.

[0012] The beneficial effects of the utility model are as follows: an automatic screening device for raw materials for the production of aluminum composite panels, in which powdered materials fall downward through a third hopper onto a rotating annular screen, and are quickly filtered by utilizing the movement and vibration of the annular screen, and qualified powdered materials fall into a guide trough and are sent to a second hopper through the guide trough, facilitating subsequent transportation, and larger particles and agglomerated materials retained on the annular screen run along with the annular screen to one end or the bottom of the annular screen, and are shaken off into the first hopper, thus realizing automatic cleaning and maintenance of the annular screen, avoiding the problem of clogging of the annular screen, and requiring no downtime, thereby greatly improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0014] Combine the following Figure 1 The technical solution of the utility model is further illustrated by specific embodiments.

[0015] like Figure 1 The automatic screening device for raw materials for producing aluminum composite panels shown in the figure comprises: a first hopper 1, a second hopper 2, a frame 7 and an annular screen 10, wherein the first hopper 1 is arranged at the bottom of the frame 7, and two parallel and spaced synchronous belts 8 are arranged in the frame 7. In this embodiment, a synchronous wheel 11 supporting the operation of the synchronous belt 8 is arranged in the frame 7, and the synchronous wheels 11 corresponding to the two synchronous belts 8 can be driven by the same rotating shaft, and the rotating shaft is driven by a motor to ensure the synchronous rotation of the two synchronous belts 8.

[0016] The annular screen 10 is connected between two synchronous belts 8 and is located above the first hopper 1 . The edges on both sides of the annular screen 10 can be fixed on the two synchronous belts 8 by rivets, and the synchronous belts 8 drive the operation of the annular screen 10 .

[0017] A material guide trough 6 extending obliquely downward from the inner side of the annular screen 10 is provided in the frame 7, and the second hopper 2 is arranged at the bottom of the material guide trough 6. In this embodiment, a third hopper 9 located above the annular screen 10 is provided on the frame 7. The powder falls onto the rotating annular screen 10 through the third hopper 9, and is quickly filtered by utilizing the movement and vibration of the annular screen 10. Qualified powder falls into the material guide trough 6 and is sent into the second hopper 2 through the material guide trough 6, so as to facilitate subsequent transportation.

[0018] A screw conveyor 3 is provided at the bottom of the second hopper 2, which can convey the qualified powder in the second hopper 2 to the silo or the stirring mechanism for subsequent production of the aluminum composite plate.

[0019] like Figure 1As shown, the larger particles and agglomerated materials retained on the annular screen 10 run to one end or the bottom of the annular screen 10 and are shaken into the first hopper 1, thereby realizing automatic cleaning and maintenance of the annular screen 10 and avoiding the clogging problem of the annular screen 10. There is no need to stop the production process, thereby improving work efficiency.

[0020] In this embodiment, a discharge valve 5 is provided at the bottom of the first hopper 1 for easy opening for discharge. A flow box 4 is provided below the discharge valve 5 for collecting larger particles and agglomerated materials, and the larger particles and agglomerated materials can be poured back into the third hopper 9 through the flow box 4 for secondary screening to improve the utilization rate of the materials.
