Intermittent feeding device

Abstract

The invention discloses an intermittent feeding device. The intermittent feeding device comprises a rack, a pushing device and a feeding device; the feeding device comprises a hopper, the hopper is fixedly installed on the rack, a discharge opening is formed in the side wall of the bottom portion of the hopper, and a bottom plate is installed at the bottom of the hopper; the pushing device comprises a pushing block, and the pushing block is connected with the bottom plate in a sliding mode; the pushing device further comprises a gas bag, an output tube, a squeezing plate and a pushing plate; the gas bag and the squeezing plate are fixedly installed on the rack; the top of the gas bag abuts against the squeezing plate; the pushing plate is connected with the rack under the gas bag in a vertical sliding mode; the output tube is installed between the gas bag and the hopper; an exit of the gas bag communicates with the output pipe; a piston sliding horizontally is connected in the output pipe; the piston is fixedly connected with the pushing block; a fixing plate is connected with the portion, located between the piston and the pushing block, of the output pipe wall; and an elastic part is connected between the piston and the fixing plate. Compared with the prior art, the intermittent feeding device has the advantage that thrust of the pushing block to materials is quiet soft in the material pushing process, so that damage to the materials caused by instantaneous crashing force of the pushing plate is avoided.

Description

technical field [0001] The invention relates to a feeding device, in particular to an intermittent feeding device. Background technique [0002] The feeder is a device that evenly discharges the material in the silo to the conveyor through the feeder, and makes the material form a material layer of appropriate thickness and width. [0003] The existing feeder consists of two parts, which are respectively a pushing device and a feeding device. The feeding device is usually a hopper, and the pushing device is a pushing block, a push rod and a cylinder, and the cylinder is fixed on the frame , the push rod is connected to the output rod of the cylinder, the push block is connected to the push rod, there is a discharge port on the side wall of the hopper, the bottom plate is welded on the bottom of the hopper, the push block is slidably connected to the bottom plate of the hopper, and the push block is used Push the material from the bottom of the hopper out of the outlet, put ...

AI Technical Summary

Problems solved by technology

[0004] The problem of the above-mentioned feeder: the cylinder directly controls the pushing block to push the material, the pushing force of the cylinder is relatively large, the pushing block will maintain a relatively high running speed and contact with the material, and the contact between the pushing block and the material will generate a large impact force , making the pushing block easy to damage the material
