Embodiment Construction

[0031] Such as Figure 1-2 As shown, an electronic measurement and weighing unit of a checkweigher, it includes a support frame 3 and at least one load cell 2 fixedly arranged on the support frame 3, and a weighing slideway 1 is fixedly arranged on the load cell 2 , the length direction of the weighing slideway 1 is at an angle A with the horizontal plane, 0°<A<90°; The length direction of the slideway 1 is vertical; when the load cell 2 is a rectangular load cell, it must be satisfied that the gravity does not generate a force component in the normal direction of the side of the load cell 2 . A weighing control instrument 4 electrically connected to the load cell 2 is also provided. The weighing slideway 1 is a rigid body made of hard wear-resistant material, which is in the form of a concave groove or a plane or a bobbin-shaped structure with openings at both ends. For example, the weighing slideway 1 can be a tank structure of stainless steel bent and then processed to co...

Abstract

The invention provides an electronic measuring and weighing unit of a checkweigher. The electronic measuring and weighing unit of the checkweigher comprises a supporting frame, and a weighing sensor which is fixedly arranged on the supporting frame; a rigid weighing chute is fixedly arranged in the weighing sensor. The electronic measuring and weighing unit of the checkweigher is characterized in that the rigid weighing chute is in an angle A with the level in the length direction, wherein A is more than 0 degree and less than 90 degrees; a rigid feeding chute is fixedly arranged in the supporting frame or a feeding device or an independent bracket; the chute is parallel to and opposite in a short distance with the weighing chute, does not contact with the weighing chute and is slightly higher than the weighing chute; the bearing end of the weighing sensor is rigidly connected with the rigid weighing chute, and the designed bearing stress direction of the weighing sensor is vertical to the length direction of the rigid weighing chute; a weighing control instrument is provided and electrically connected with the weighing sensor.

Description

technical field [0001] The proposal relates to an electronic weighing unit of a checkweigher, which is mainly used for automatic dynamic weight detection of intermittent bulk materials. Background technique [0002] All electronic weighing equipment (including: electronic scales) feel the weight of the object being weighed through sensors. Most electronic weighing devices use force sensors or load cells to measure the local gravity of objects. As we all know, the gravity of an object is perpendicular to the horizontal plane where the object is located. For a long time, when the force sensor or load cell is used, the installation method, force point and direction are strictly specified, so as not to affect the accuracy of the sensor. In order to reduce the component deviation of the sensor, almost all sensor manufacturers, weighing equipment manufacturers, textbooks, weighing industry standards and specifications, training materials, and equipment operation and debugging in...
