Particle material feeding device

Abstract

The invention discloses a particle material feeding device. The particle material feeding device comprises two mounting plates, wherein a rotary shaft seat and a V-shaped swing frame are mounted between the two mounting plates, a rotary shaft is arranged in the middle of the rotary shaft seat in a penetrating mode, one end of the rotary shaft is in threaded connection with a swing shaft hinged tothe upper end of the swing frame, a swing arm is connected between the two mounting plates through a swing arm shaft, the two ends of the swing arm shaft are sleeved with sliding blocks respectively and inserted into longitudinal sliding grooves formed in the two mounting plates through the sliding blocks, and the front end of the swing frame is in a fork shape and inserted into the swing arm shaft; a metering bottom plate is fixed between the front ends of the two mounting plates, a metering cover is hinged to the lower end of the swing arm, a wedge-shaped groove is formed in the metering cover and matched with the metering bottom plate to form a material accommodating cavity, a discharging air cylinder is mounted between the two mounting plates through an air cylinder base plate, and thefront end of a piston rod is clamped in a long hole formed in the lower portion of the swing arm in the longitudinal direction through a connector by using a pin shaft. The particle material feedingdevice has the advantages that manual or automatic adjustment of the loading amount can be achieved, and accurate loading amount is ensured; and the device is compact in structure and reliable in work.

Description

technical field [0001] The invention relates to a feeding device, in particular to a granular material feeding device with an adjustment function. Background technique [0002] The granular material feeding device is installed on the granular packaging machine to realize the metering and blanking of granular materials. The existing granular material feeding device mostly adopts an old-fashioned swing feeding machine, including a motor and a crank slider mechanism. The reciprocating sliding of the crank slider mechanism drives a swing bar to swing left and right, and the swing bar is installed with corresponding multi-row strips. A plurality of metering covers are opened or closed by swinging the pendulum to open or close the metering covers to realize opening or closing. This kind of feeding device is inconvenient to adjust the loading amount, and cannot realize the automatic adjustment of the loading amount, and because the old-fashioned swing feeding machine is mostly use...

AI Technical Summary

Problems solved by technology

This kind of feeding device is inconvenient to adjust the loading amount, and cannot realize the automatic adjustment of the loading amount, and because the old-fashioned swing feeding machine is mostly used in multi-row bag packaging machines, it often occurs due to insufficient processing accuracy, installation errors and fatigue. Deformation leads to problems such as poor closing of the metering cover
