Check-weigher

Abstract

The invention discloses a check-weigher. The check-weigher comprises a feeding device and a horizontally arranged weighing slide-way, and a weighing sensor is arranged below the weighing slide-way; the check-weigher further comprises a weighing control meter electrically connected with the weighing sensor; the weighing slide-way is a rigid passage, wherein the surface of the rigid passage in contact with material is a smooth groove, the axial line direction of the groove is arranged horizontally, and the axial line direction of the groove is consistent with the material running direction.

Description

technical field [0001] The proposal relates to a checkweigher whose measurement unit adopts a horizontal inertia weighing slideway, and is mainly used for automatic dynamic weight detection of intermittent bulk materials. Background technique [0002] The automatic dynamic weight detection of intermittent bulk materials refers to the uninterrupted dynamic weighing detection during the operation of the object being weighed. Blocky materials include but are not limited to hard materials, soft elastic materials, bagged materials, boxed materials, bottled materials, boxed materials, bundled materials, serially connected materials, and bonded materials. [0003] Checkweigher refers to a dynamic automatic electronic weight detection scale using a load cell, most of which use a belt to convey materials, also known as sorting scales, sorting scales, sorting scales, sorting scales, re-inspection scales, grading scales, etc. Class sorting scales, weight labeling scales, etc., are mai...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned weighing power belt has always had the following problems: the vibration or jump caused by the unbalanced mass of the driving motor, synchronous belt, conveyor belt, roller and other rotating parts seriously affects the weighing accuracy; the connection between the driving motor cable and the outside affects the weighing and measuring unit. Freedom, which in turn affects the weighing accuracy; the invalid weight of its own mechanical structure also affects the weighing accuracy; the high-precision machining cost of the moving parts affects the economy and maintenance cost of the weighing unit of the checkweigher; the speed limit of each rotating part is determined The efficiency of sorting cannot be greatly improved; the rotating parts are difficult to achieve high-level protection and the requirements of food, medicine and hygiene seriously restrict the scope of use of the weighing unit of the sorting scale

It can be seen that the rotating moving parts in the weighing power belt seriously affect the weighing accuracy, economy and practicability of the checkweigher
