Description

Technical Field

[0001] The utility model relates to the technical field of feeding, in particular to a powder feeding device. Background Art

[0002] At present, the main powder feeding methods used are glove box feeding, manual suction gun feeding and semi-automatic feeding.

[0003] Glove box feeding is done by manually carrying powder bags into the glove box, then manually opening the bags through isolation gloves and manually dumping the powder bags to achieve loading. This method is labor-intensive, low-efficiency, and dusty. It is necessary to open and close the glove box door, and it is not easy to control dust in the workshop.

[0004] Before use, powder materials go through two stages: storage and transportation. During transportation, the powder materials are shipped in bags. During the storage stage, the powder materials may clump due to various reasons. The clumped powder materials will affect the processing quality during subsequent use. Therefore, the lumps that may exist in the powder materials need to be crushed before use to ensure processing efficiency. Utility Model Content

[0007] Preferably, the first linkage shaft and the second linkage shaft are both axially connected to the inner wall of the base.

[0008] Preferably, the lower end of the base is fixedly connected to a feed chute, one side of the feed chute is fixedly connected to a second motor, and a powder crushing shaft is provided in the middle of the second motor.

[0009] Preferably, one side of the base is fixedly connected to the placement rack, one side of the placement rack is fixedly connected to the third motor, and a push plate is provided in the middle of the third motor.

[0010] Preferably, the base is fixedly connected to a fourth motor on a side close to the first bag breaking cutter, and one end of the fourth motor is connected to a hook plate via an output shaft.

[0012] Preferably, a plurality of legs are fixedly connected to the bottom end of the base.

[0013] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0014] First, the utility model can reduce the workload of workers by providing a first motor and a first bag breaking knife. The first motor drives the driving block to rotate, and the driving block pushes the first connecting rod and the second connecting rod at both ends. The first connecting rod pushes the first bag breaking knife, and the second connecting rod pushes the second bag breaking knife. The first bag breaking knife and the second bag breaking knife move inward at the same time to contact the powder bag, thereby cutting the powder bag, thereby reducing the workload of workers and improving work efficiency.

[0015] Secondly, the utility model can break up the powder by setting up the feeding chute and the powder crushing shaft. The second motor drives the powder crushing shaft to break up the agglomerated powder. At the same time, the powder is buffered by the buffer plate and screened by the sieve holes to avoid impurities being mixed in the powder, thereby improving the quality of the powder.

[0016] Third, the utility model can process the bag breaking knife by arranging the fourth motor and the hook plate. The fourth motor drives the hook plate to rotate so as to hook the powder bag on the first bag breaking knife, thereby preventing the powder bag from being entangled in the device and ensuring the operation of the device.

[0017] Fourthly, the utility model can reduce the contact between workers and the device by providing the third motor and the push plate. When the powder bag is placed on the placement rack by manpower, the third motor pushes the push plate to move inward. The push plate moves inward, thereby driving the powder bag to move inward, reducing the contact between workers and the internal mechanism of the device, and providing certain protection for the personal safety of workers.
