Feeding device and powder material packaging machine

Abstract

The application discloses a feeding device and a powder material packaging machine. The feeding device comprises a machine table, a rotating disc mechanism connected to the machine table and a material distribution partition. The machine table is provided with a driving assembly connected with the rotating disc mechanism and capable of driving the rotating disc mechanism to rotate. The rotating disc mechanism is provided with a cavity. The bottom wall of the cavity is provided with a downwardly recessed metering cavity. The material distribution partition is located in the cavity and has a first partition part, a second partition part and a distribution part. The first partition part, the second partition part and the distribution part are all arranged at intervals relative to the circumferential wall of the cavity. The first partition part and the second partition part are arranged at intervals and form a discharging area therebetween. The metering cavity can move in and out of the discharging area with the rotation of the rotating disc mechanism. The distribution part is located on the entering side of the discharging area and is connected with the first partition part and the second partition part respectively, and can distribute the powder material in the cavity to both sides of the distribution part. The application can reduce the accumulation of the powder material in front of the material distribution partition, and is beneficial to the normal discharging and conveying of the powder material.

Claims

1. A feeding device, characterized in that, include: The machine tool is equipped with a drive assembly; A turntable mechanism is provided on the machine base and connected to the drive assembly. The turntable mechanism has a cavity for placing powder materials. The bottom wall of the cavity has a downwardly recessed metering cavity. The drive assembly can drive the turntable mechanism to rotate. A material distribution partition, connected to the machine base and located within the cavity, comprises a first partition, a second partition, and a diversion section. These partitions are spaced apart from the peripheral wall of the cavity. The first and second partitions are spaced apart and form a discharge area between them. The metering cavity can move in and out of the discharge area with the rotation of the turntable mechanism. The diversion section is located on the entry side of the discharge area and is connected to both the first and second partitions. The diversion section can divert powder material in the cavity to both sides. The diversion section has a "V"-shaped plate structure. Both the first and second partitions have arc-shaped plate structures, guiding the powder material in the cavity to be conveyed in the direction of rotation of the turntable mechanism. A scraper is connected to the lower side of the material distribution partition, and the scraper has a spring-loaded... The material distribution plate is elastically and abuts against the bottom wall of the cavity. A connecting member is provided between the material distribution plate and the machine base, and the connecting member can adjust the relative position of the material distribution plate in the cavity. An air blowing channel is provided on the lower side of the metering cavity. A one-way valve is provided between the metering cavity and the air blowing channel, so that the airflow of the air blowing channel can enter the metering cavity and restrict the powder material in the metering cavity from entering the air blowing channel. The machine base is provided with a first driver and a second driver. The first driver drives and connects to a first moving seat. The first moving seat is provided with a discharge pipe. The first driver can drive the first moving seat to move so that the discharge pipe docks with the metering cavity. The second driver drives and connects to a second moving seat. The second moving seat is provided with an air blowing pipe. The second driver can drive the second moving seat to move so that the air blowing pipe docks with the air blowing channel.

2. The feeding device according to claim 1, characterized in that, The discharge pipe can be moved and adjusted relative to the first moving seat and / or the air blowing pipe can be moved and adjusted relative to the second moving seat.

3. The feeding device according to claim 1, characterized in that, The discharge pipe is provided with a first elastic element. When the discharge pipe is connected to the metering cavity, the first elastic element is in a compressed state and acts on the discharge pipe.

4. The feeding device according to claim 1, characterized in that, An elastic ring is provided at the opening of the discharge pipe. When the discharge pipe is connected to the metering cavity, the elastic ring abuts against the bottom wall of the cavity.

5. A powder material packaging machine, characterized in that, Includes the feeding device according to any one of claims 1 to 4.

6. The powder material packaging machine according to claim 5, characterized in that, It also includes a frame and a film feeding device, a heat-sealing packaging forming device, and a cutting device disposed on the frame. The film feeding device is disposed on the frame. The film feeding device is used to convey film material. The heat-sealing packaging forming device is used to roll the film material into a strip-shaped package with a cavity and heat-seal the strip-shaped package. The film feeding device can convey powder material into the cavity of the strip-shaped package. The cutting device is used to cut the heat-sealed strip-shaped package.
