Light reflecting device special for verification of weighing feeder

Abstract

The utility model discloses a special light reflecting device for checking a weighing feeder. In the prior art, a manual visual inspection or paper pasting mode is used for verification of a weighing feeder, the verification is greatly influenced by external factors, a conveying belt is prone to falling off when the conveying belt is wet, time and labor are wasted, interference of human factors is prone to occurring, and the verification result is not accurate enough. The light reflecting plate comprises a light reflecting plate body (2), a first light reflecting sticker (1) and a second light reflecting sticker (3) are pasted on the light reflecting plate body, and clamping devices (4) are fixed to the four corners of the light reflecting plate body respectively. The clamping device comprises a buckling box (42), a U-shaped clamping plate (41) is arranged in the buckling box in a penetrating mode, one end of the U-shaped clamping plate is fixed to a hook face belt (44), and the hook face belt adheres to a net face belt (43) at the top of the buckling box. The weighing feeder checking device is used for checking the weighing feeder.

Description

Technical Field

[0001] The utility model relates to a special reflective device for checking a weighing feeder. Background Art

[0002] Weigh feeder is a continuous weighing device widely used in thermal power plants, mines and other industries. For this type of equipment, regular calibration is required to ensure its measurement accuracy. In the past, weigh feeder calibration used manual visual observation or stickers, which were greatly affected by external factors and easily fell off when the conveyor belt was wet. It was not only time-consuming and labor-intensive, but also easily interfered by human factors, resulting in inaccurate calibration results. Utility Model Content

[0003] The utility model aims to solve the above-mentioned problems and provides a special reflective device for checking a weighing feeder.

[0004] The above purpose is achieved through the following technical solutions:

[0005] A reflective device for weighing feeder calibration, comprising a reflective plate body, a first reflective sticker and a second reflective sticker pasted on the reflective plate body, and four corners of the reflective plate body are respectively fixed with clamps;

[0006] The clamp comprises a buckle box, a U-shaped clamp is inserted into the buckle box, one end of the U-shaped clamp is fixed to a hook surface belt, and the hook surface belt is adhered to the mesh surface belt on the top of the buckle box.

[0007] The reflective device specially used for checking the weighing feeder, the reflective plate body is a flexible reflective plate. Beneficial Effects

[0008] 1. The utility model can be clamped on a conveyor belt and used for checking the conveyor belt during transmission, which can prevent the reflective sticker from falling off and ensure the accuracy of the check.

[0009] 2. The utility model has a simple structure, and the positions of the four clamps can be adjusted according to the width of the conveyor belt so that the four clamps can be clamped on the conveyor belt. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Reference Figure 1-Figure 4 A reflective device for weighing feeder calibration, comprising a reflective plate body 2, the reflective plate body being a flexible reflective plate, a first reflective sticker 1 and a second reflective sticker 3 being attached to the reflective plate body, the reflective spectrum characteristics of the first reflective sticker being different from the reflective spectrum characteristics of the second reflective sticker, and a clamp 4 being fixed to the four corners of the reflective plate body;

[0018] The clamp comprises a buckle box 42, in which a U-shaped clamp 41 is inserted, one end of the U-shaped clamp is fixed to a hook surface belt 44, and the hook surface belt is adhered to the mesh surface belt 43 on the top of the buckle box.

[0019] Working principle: Refer to Figure 5-Figure 6 When in use, separate the hook belt of each clamp from the mesh belt, slide the U-shaped clamp, then place the reflector body on the conveyor belt, slide each U-shaped clamp so that the U-shaped clamp clamps the conveyor belt, and after clamping, the U-mouth of the U-shaped clamp is against the side wall of the conveyor belt, and then the hook belt is attached to the mesh belt on the buckle box. After adjusting the position of the four clamps, the clamping of the device is realized, and then the calibration work is carried out.

Claims
