Description

Technical Field

[0001] This utility model relates to the technical field of powder material conveying equipment, specifically to a residual powder discharge device at the end of a powder feeding line. Background Technology

[0002] The existing automatic powder feeding line cannot properly discharge powder at the end and add powder to the spiral powder hopper. Flour or soybean powder needs to be discharged through the last discharge port. During the discharge operation, the machine needs to be stopped and manually operated. After the discharge is completed, powder cannot be continuously added to the spiral powder hopper. Powder addition still needs to be done manually, which increases the workload of personnel and leads to labor waste. Moreover, the powder discharge and powder addition operations cannot be carried out continuously, which wastes operation time and reduces production efficiency. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a residual powder discharge device at the tail end of a powder feeding line. The device temporarily stores the falling material in a transfer hopper, thereby controlling the material's falling speed. Simultaneously, a reversing valve plate controls the material conveying direction, preventing overflow or blockage of the discharge port due to material accumulation in the hopper.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a powder discharge device at the tail end of a powder feeding line, comprising a transfer box, a receiving hopper at the top of the transfer box, a first discharge port at the bottom, a second discharge port on one side of the transfer box, a reversing valve plate in the middle of the transfer box, and a driving device connected to the reversing valve plate on the outside of the transfer box.

[0005] As a further improvement to the above technical solution:

[0006] The drive device includes a telescopic rod, and the movable end of the telescopic rod is provided with an adapter rod that is connected to the reversing valve plate.

[0007] One end of the adapter rod is connected to the telescopic rod via a spherical bearing, and the other end is provided with a bearing seat.

[0008] One end of the reversing valve plate is rotatably connected to the side wall of the transfer box, and the other end is provided with an extension rod connected to the drive device. The side wall of the transfer box is provided with a clearance groove for use with the extension rod.

[0009] The clearance groove is arc-shaped, and sealing gaskets are provided on the side walls of the transfer box on both sides of the clearance groove.

[0010] One end of the extension rod is connected to the reversing valve plate, and the other end is provided with a sealing block, the diameter of which is greater than the width of the clearance groove.

[0011] The beneficial effects of this utility model embodiment are as follows: The residual powder discharge device at the end of the powder feeding line includes a transfer box, a receiving hopper at the top of the transfer box, a feeding port at the top of the receiving hopper, a first discharge port connected to the discharge hopper at the bottom of the transfer box, a second discharge port on one side of the transfer box, a reversing valve plate in the middle of the transfer box, and a driving device connected to the reversing valve plate on the outside of the transfer box. The transfer box temporarily stores the falling material, thereby controlling the falling speed of the material. At the same time, the reversing valve plate controls the material conveying direction, preventing the material from accumulating in the discharge hopper and overflowing or blocking the discharge port. The transfer box can complete the temporary storage and discharge of materials, and can complete the powder feeding and discharge operations, improving the continuity of the operation and reducing manual intervention.

[0016] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0017] like Figure 1-3 As shown, the residual powder discharge device at the end of the powder feeding line in this embodiment includes a transfer box 1. The upper part of the transfer box 1 is provided with a receiving hopper 2, and the upper part of the receiving hopper 2 is provided with a feeding port. The lower part of the transfer box 1 is provided with a first discharge port 3 connected to the discharge hopper. A second discharge port 4 is provided on one side of the transfer box 1. The design of the two discharge ports can transport materials to different directions. The middle part of the transfer box 1 is provided with a reversing valve plate 5. The outside of the transfer box 1 is provided with a drive device connected to the reversing valve plate 5. The drive device drives the reversing valve plate 5 to alternately seal the first discharge port 3 and the second discharge port 4, thereby changing the conveying direction of the material. When the material height in the discharge hopper is too high, the material is discharged through the second discharge port 4.

[0018] During manufacturing, the side of the transfer box 1 opposite to the second discharge port 4 is designed with a hollow structure. The upper end of the reversing valve plate 5 is rotatably connected to the transfer box 1 through a rotating shaft. The lower end of the reversing valve plate 5 is provided with a sealing step. During normal material feeding, the reversing valve plate 5 replaces the side wall of the transfer box and plays a sealing role. When reversing is required, the reversing valve plate 5 rotates upward, and the material falls along the reversing valve plate 5 and is discharged from the second discharge port 4.

[0019] In operation, an infrared sensor is installed below the transfer hopper 1 to detect the material height in the hopper. When the material height reaches the set value, the sealing valve plate 5 rotates upward, and the telescopic rod 6 is driven by a cylinder. A solenoid valve is installed on the cylinder, and the control panel connects to the solenoid valve and the infrared sensor. When the infrared sensor detects that the material height has reached the set value, the control panel receives the signal and sends an operation command to the solenoid valve to complete the material discharge operation, replacing manual monitoring and improving operational efficiency and continuity.

[0020] The drive device includes a telescopic rod 6. The movable end of the telescopic rod 6 is provided with a transition rod 7 connected to the reversing valve plate 5. One end of the transition rod 7 is connected to the telescopic rod 6 through a spherical bearing 8, and the other end is equipped with a bearing seat 9. The transition rod 7 is L-shaped and is used to connect the telescopic rod 6 and the reversing valve plate 5. The telescopic rod 6 is used to drive the reversing valve plate 5 to rotate, thereby realizing the reversing conveying of materials.

[0021] One end of the reversing valve plate 5 is rotatably connected to the side wall of the transfer box 1, and the other end is provided with an extension rod 10 connected to the drive device. The side wall of the transfer box 1 is provided with a clearance groove 11 that works with the extension rod 10. The clearance groove 11 is arc-shaped and has the same rotation trajectory as the reversing valve plate 5. The side wall of the transfer box 1 is provided with sealing gaskets 12 located on both sides of the clearance groove 11. One end of the sealing gasket 12 is in contact with the side wall of the transfer box 1, and the other end is provided with sealing comb teeth. When the extension rod 10 is sliding or stationary, the sealing gasket 12 is used to seal the clearance groove 11 to prevent material from escaping to the outside of the transfer box 1.

[0022] One end of the extension rod 10 is connected to the reversing valve plate 5, and the other end is provided with a sealing block 13. The diameter of the sealing block 13 is larger than the width of the clearance groove 11. The sealing block 13 covers the outside of the clearance groove 13, making up for the gap between the extension rod 10 and the clearance groove 11, and cooperating with the sealing gasket 12 to perform double sealing and improve the sealing effect.
