Description

Technical Field

[0001] The utility model relates to the technical field of vacuum fillers, in particular to a separation type vacuum filler. Background Art

[0002] The filler is a conveying and feeding equipment that replaces manual feeding. The existing filler includes a pellet silo, a vacuum pump and a hopper. When the filler is working, the vacuum pump sucks the pellets in the pellet silo into the hopper and then feeds them out of the hopper to achieve the purpose of filling. Since the pellets contain a lot of dust, a filtering device is required to filter the dust in the silo to prevent the dust from entering the vacuum pump and causing damage to the vacuum pump.

[0003] At present, a separation type vacuum filler, such as the separation type vacuum filler described in the patent with announcement number CN210392932U, comprises: a hopper body, the surface of the hopper body is provided with a material feeding and discharging mechanism, the bottom end of the hopper body is provided with a supporting mechanism, the left side wall of the hopper body is provided with a movable basket, the right side of the movable basket extends to the inside of the hopper body and is fixedly provided with an elastic filter net, and the left side of the movable basket is fixedly provided with a placement plate. The utility model is provided with a cleaning rod, an electric push rod, a push block, a vertical plate and a telescopic spring, so that the electric push rod drives the push block to move upward, pushes the cleaning rod to rotate to the left and separates from the elastic filter net, and when the electric push rod drives the push block to move downward, the telescopic spring resets and stretches to push the cleaning rod to rotate to the right quickly, so that the cleaning rod knocks on the surface of the elastic filter net, which is conducive to the dust accumulated on the surface of the elastic filter net falling, effectively preventing the elastic filter net from being blocked, and having a better use effect.

[0004] In view of the above-mentioned related technologies, the applicant found that when a separate vacuum filler is used, two electric push rods are used to drive two cleaning rods separately, so as to achieve the effect of cleaning the elastic filter screen. However, when the two electric push rods are driven at the same time, the energy consumption of the device is greatly increased, and the cost of the device is increased during use. Therefore, we propose a separate vacuum filler. Utility Model Content
