Automatic weighing charging machine

Abstract

The invention discloses an automatic weighing charging machine. The automatic weighing charging machine comprises a feed hopper. A weighing sensor is arranged on the side face of the feed hopper. A spiral feed device is arranged above the feed hopper. A small-amount feed layer board device is arranged below the outlet position of the spiral feed device. The small-amount feed layer board device is arranged on a base. The base is movably arranged below the spiral feed device. The small-amount feed layer board device comprises an obliquely-arranged layer board, the layer board is connected to an installation shaft, the installation shaft is driven by a vibrating device to vibrate leftwards and rightwards, the vibrating device is arranged on the base, a small hopper is arranged above the layer board, an extensible and retractable baffle is arranged at the outlet position of the small hopper, and the baffle is perpendicular to the layer board. The automatic weighing charging machine is reasonable in structure set and smooth in running, interference does not occur, the small-amount feed layer board device moves to the position below the spiral feed device at the later feed period of the spiral feed device, small-amount supplementation feed is carried out, and the problems that the feed flow is too large and consequently feed is too much or too small is solved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to an automatic weighing feeder. Background technique [0002] Feeder is a commonly used equipment in material feeding, processing and packaging, especially for powder materials, the use of feeder is more extensive. Since many materials have certain requirements on the added weight in the process of adding materials, the existing feeding machine has also added a structure for weighing the weight of materials, but it is always easy to add inaccurate phenomena in the process of adding materials. It leads to either more or less. This puts forward high requirements on the equipment for conveying materials. If all the conveying equipment is improved, the cost will be too high. Therefore, it is considered to set up auxiliary devices, and the auxiliary conveying equipment can add and feed materials more accurately. Contents of the invention [0003] The technical problem t...

Problems solved by technology

[0003] The technical problem to be solved in the present invention is that in the existing feeding machine, the material feeding transmission is not accurate enough, and the phenomenon of adding more or less will appear, resulting in the low accuracy of the feeding machine

The automatic weighing feeder of the present invention has a reasonable structure, smooth operation, and no interference with each other. The small-dose feeding pallet device moves to the bottom of the screw feeding device in the later stage of feeding the screw feeding device to perform small-dose supplementary feeding. Avoid too much feed flow, resulting in the problem of adding more or less
