Description

Technical Field

[0001] This utility model relates to the field of material feeder technology, specifically a material feeder for powder feeding and conveying. Background Technology

[0002] Powder feeding and conveying feeders are key equipment used in industrial production to control the uniform and stable feeding of powder materials. Their core function is to break up the accumulated powder and convey it to downstream equipment through a mechanical structure, while avoiding problems such as blockage and arching.

[0003] Most existing feeders are fixed cross-shaped, requiring replacement of the entire feeder when the blades are physically damaged, resulting in high maintenance costs. Therefore, those skilled in the art have provided a feeder for powder feeding and conveying to solve the problems mentioned in the background section. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a powder feeding and conveying device, which solves the problem that existing feeding devices require replacement of the entire device when the blades are physically damaged, resulting in high maintenance costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a powder feeding and conveying device, comprising a drive shaft, a mounting plate installed at one end of the drive shaft, a slot provided on the periphery of the mounting plate, a paddle inserted into the slot, a positioning hole provided at one end of the paddle in the slot, a positioning groove provided vertically in the slot, a horizontal plate installed horizontally in the positioning groove, a positioning bolt inserted vertically in the slot, a through groove provided in the middle of the positioning bolt, a limit rod installed vertically in the through groove, and a spring sleeved on the limit rod.

[0006] Preferably, the horizontal plate extends horizontally through the through groove, the limiting rod extends vertically through the horizontal plate, the bottom end of the spring presses against the bottom inner wall of the through groove, and the top end of the spring presses against the bottom side wall of the horizontal plate. Under the action of the spring, the positioning bolt is always pressed downward, thereby engaging with the positioning hole at the end of the leaf blade in the insertion slot, thereby fixing the leaf blade.

[0007] Preferably, the leaf is slidably inserted into the mounting plate via a slot, and the positioning bolt is positioned and inserted into the positioning hole. By pulling the positioning bolt upward, the positioning bolt is disengaged from the positioning hole, and the leaf can be removed from the slot for replacement.

[0008] Preferably, a threaded groove is formed on the upper circumference of the placement plate, and a protective cover is provided on the top of the placement plate. The protective cover is threadedly connected to the placement plate through the threaded groove, which can protect the positioning bolt and prevent dust from entering the gap of the positioning groove.

[0009] Compared with the prior art, the present invention provides a powder feeding and conveying device, which has the following beneficial effects: The design employs a V-shaped slot to engage with the deflector blade, and the blade is secured by a positioning bolt that inserts into the positioning hole at the end of the blade. This robust structure ensures the stability of the blade during operation. Furthermore, the positioning bolt, through the cooperation of a horizontal plate, a limiting rod, and a spring, maintains a constant downward pressure, ensuring a tight fit between the positioning bolt and the positioning hole of the blade. This further enhances the reliability of the blade's fixation. When the blade needs to be replaced, simply unscrew the protective cover and pull the positioning bolt upwards to disengage it from the positioning hole, allowing the blade to be easily removed from the slot for replacement. This simple and quick operation improves work efficiency and reduces maintenance costs. Attached Figure Description
