Problems solved by technology

[0004] However, the weighing object dropped by the micro-feeding mechanism (c') and the feeding device (b') of the aforementioned metering device directly falls into the weighing cylinder (10'), and the drop between it and the weighing cylinder (10') is large. , the reaction time of the weighing is long and the acceleration of gravity when the weighing object falls will affect the sensing accuracy of the load cell (20'), so it has the disadvantage of not being able to accurately measure and count

Embodiment Construction

[0032] First, please refer to Figure 4 , 5 , shown in 6, metering device of the present invention comprises: a weighing tube (10), a load element (20), a opening and closing mechanism (30);

[0033] The weighing tube (10) is formed by pivoting a fixed box plate (11) and a movable box plate (12), and at least one weighing plate (121) of appropriate size and height is arranged on the inside of the movable box plate, And this fixed box plate (11) outside must be provided with a projection (111), when fixed box plate (11) and a movable box plate (12) are closed, can undertake weighing object;

[0034] The load element (20) is placed on the side of the fixed box plate (11) of the weighing cylinder (10), and is sent into the weighing cylinder (10) to measure the weight of the weight;

[0035] This opening and closing mechanism (30) is constituted by a moving rod (31) and a driving member (32). 31), the moving bar (31) is located at a suitable place on the outside of the movable ...

Abstract

A metering device, including a weighing cylinder, which is formed by the pivot connection of a fixed box plate and a movable box plate, and can accept and weigh objects when the movable box plate is closed. When the measurement reaches a preset value, the movable box The plate is opened with the pivot point as the fulcrum so that the weighing objects inside can enter the packaging bag; a load cell can weigh the weight of the weighing objects sent into the weighing cylinder; an opening and closing mechanism is located outside the movable box plate, with a Move the rod to open or close the movable box plate; at least one weighing plate is arranged inside the movable box plate, which can reduce the drop of the weighing object and achieve more accurate measurement of the weighing object.

Description

【Technical field】 [0001] The invention relates to a metering device. 【Background technique】 [0002] The structure of conventional metering devices (please refer to figure 1 As shown), its feeding cylinder (a') is placed above a feeding device (b'), and the weighing objects are fed into a feeding device (b') in sequence, and the feeding device (b') at the end ') Drop the weighing object into the weighing cylinder (10'), and slow down when the load cell (20') on one side of the weighing cylinder (10') senses that the weighing object in the cylinder reaches the preset value The feeding speed can make the weighing object be sent out in a small amount or in a single way, and when the preset value is reached, the feeding will be stopped and the movable box plate of the opening and closing mechanism (30') will be opened, so that the weighing object falls into the packaging bag and the weighing action is completed . Please also refer to figure 2 As shown, it is equipped with a...
