Weighing apparatus

Abstract

The invention discloses a weighing apparatus. The weighing apparatus comprises: a weighing bench and a guiding material lifting platform. The weighing bench possesses several loading plates and a load cell. The several loading plates are parallelly arranged with an interval on a top of the load cell. And the tops of the loading plates form a recess whose center is low and two sides are high. The guiding material lifting platform can be arranged on the top of the weighing bench in a lifting way. The guiding material lifting platform possesses a feeding material end and a discharge end. A guiding material lifting platform height gradually decreases from the feeding material end to the discharge end and the guiding material lifting platform is inclined. The guiding material lifting platform is provided with a plurality of through grooves corresponding to the several loading plates along an inclined direction. When the guiding material lifting platform descends to a preset position, the recesses of the loading plates can extend out of an inclined surface of the guiding material lifting platform. By using a technical scheme of the invention, steps of material supporting, weighing and feeding and the like can be rapidly completed so as to improve an object weight detection efficiency. The objects to be detected, such as good products and defective products, can be accurately separated so as to improve an object screening accuracy rate.

Description

technical field [0001] The invention relates to a weighing device, in particular to a weighing device for measuring the weight of blanks of machining objects. Background technique [0002] Before carrying out specific mechanical processing steps, the blanks of appropriate size are selected to avoid too small blanks that cannot be processed, or too large blanks to cause excessive processing waste and waste, and even cause damage to molds (such as forging molds). Among them, generally, the screening method for blanks with approximately the same appearance is achieved by weighing; taking pipe fittings as an example, the long pipes obtained by extrusion are cut off, and the cut pipes are weighed one by one. Detect whether the pipe fittings meet the requirements of subsequent processing, to screen out the defective blanks that are too light or too heavy, so as to ensure the quality of the product.

Problems solved by technology

[0003] However, the current detection method is carried out manually. The inspector needs to place the blanks to be tested on a weighing device one by one. After reading the weight value, it is judged whether the blanks are good or bad. The billet is removed and put into the corresponding collection area

Therefore, this manual inspection method is not only time-consuming and laborious, but the detection efficiency is not high, and the detection efficiency is closely related to the concentration of the inspectors; moreover, this manual inspection method is also prone to errors in the judgment of the inspectors, and the defective products are mistakenly put back. Due to the situation in the good product collection area, there is always a risk of error in the screening of blank materials
