Abstract

The utility model relates to a material feeding mechanism for a wall-plate shaping machine, relating to an improved material feeding mechanism. The material discharge port of a material hopper is arranged on the opening of a guide pipe. A threaded rod passes through the guide pipe, which enables a material feeding channel to be formed by the material hopper, the guide pipe and the threaded rod. The utility model has the different proposal that a vibrator is connected with the material hopper through a connecting frame. One end of the connecting frame is connected with the material hopper and the other end is fixed to a vibrating plate. The vibrating force is transferred to the material hopper whose rigidity is poor by the vibrator through the rigid connecting frame, which enables the material hopper to generate three-dimensional synthesis vibration. Thus the material has a larger flow rate corresponding to the material hopper. The thickness of a boundary layer is thinned and thus the material can not be agglomerated, and the material loading is even and fluent.

Description

The feed mechanism of wall panel forming machine

The utility model relates to a kind of feed mechanism of the wall panel forming machine that has improved.

The structure of existing wall panel forming machine feed mechanism is as follows, the relative frame of hopper is fixed and discharging opening places on the opening of conduit, hopper and conduit, screw rod is formed feeding channel, material places hopper and enter forming cavity from discharging opening through conduit under the effect of deadweight and screw rod, forming cavity is provided with vibrating plate, vibration effect lower bearing bracket at vibrating plate also will vibrate, make hopper produce the dither of little amplitude thereupon, because material is the fluid with viscosity, meet hydromechanical boundary layer theory, promptly constitute the border of material at the hopper wall, under the effect of viscous drag, the thickness in boundary layer is very big, the dither that adds the little amplitude of elevating hopper rolls the material at discharging opening place up and down and is bulk, and this makes the material density inequality that obtains in the forming cavity, directly influence the quality of forming wall plate, also the discharging opening of hopper can be stopped up when serious.

The purpose of this utility model is improved the feed mechanism that has wall panel forming machine, designs a kind of new feed mechanism, solves the problem of feeding inequality and obstruction discharging opening.

For achieving the above object, the utility model adopts following technical scheme, and discharging opening that will hopper places on the opening of conduit, and screw rod passes conduit, makes hopper and conduit, screw rod surround feeding channel, and different is that vibrator is connected with hopper by link.

Link one end is connected with hopper, and the other end is fixed on the vibrating plate.

By above scheme as seen, vibrator is passed to the relatively poor hopper of rigidity by the link of rigidity with exciting force, hopper is produced contain vertical, horizontal and vertical three-dimensional resultant vibration, the amplitude of this vibration is bigger, thereby make the relative hopper of material that bigger flow velocity be arranged, boundary layer thickness attenuate, material can't conglomerations, and blanking is evenly smooth.

Fig. 1 is the structural representation of embodiment, omitted and other irrelevant parts of the utility model theme for saying something, screw rod 3 left ends connect with reduction box, its thread segment is contained in the conduit 2, the bar section of finding time stretches into forming cavity, elasticity is connected between hopper 1 and the frame 7,3 outlets are fastened on the frame 7 decompression plate 8 near conduit, vibrating plate 6 is arranged near decompression plate 8, link 5 left ends and hopper 1 bottom are fastening, right-hand member and vibrating plate 6 middle parts are fastening, vibrator 4 is fixed on the link 5, when vibrator 4 vibrations, drive vibrating plate 6 on the one hand along the four root post up-down vibration that are fixed on the frame 7, simultaneously, make the three-dimensional vibrating of hopper 1 work by link 5, thereby finish feeding smoothly than large amplitude.
