Description

Technical Field

[0001] The utility model relates to the technical field of weighing instruments, in particular to a weighing device for food quality inspection with high stability. Background Art

[0002] Measurement and quality-related data generally refers to weight. Weighing is a proprietary term in the weighing industry. Weighing products include chemicals, machinery, electronics, food, grain, feed, construction materials, petroleum, metallurgy, etc. Food refers to various finished products or raw materials for human use or drinking. It is the most basic substance for human survival and development. The so-called food actually refers to food products for people to eat, which can maintain, improve or regulate the body's metabolic function and are nutritious, functional and diverse.

[0003] Usually, when manufacturers produce food, there will be food weighing devices on the production line to control the quality of the produced food. After the food is produced, it is also necessary to send the food for inspection to see if it is qualified. The weighing inspection of food is mostly done by placing the food on a weighing instrument for weighing. The weighing instrument needs to be leveled before the weighing inspection. Although most existing weighing instruments are equipped with height-adjustable feet, the leveling process is to increase the length of the feet extended from the concave part of the plane. After the extended length of the feet is increased, the feet can support the concave plane. However, the concave part is often accompanied by a curved surface or an inclined surface, and the angle of the bottom surface of the feet cannot be adjusted, resulting in a low fit between the feet and the concave part, which will also make the weighing instrument unstable.

[0004] Therefore, we propose a weighing device for food quality inspection with high stability. Summary of the Invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides a weighing device for food quality inspection with high stability.

[0006] In order to achieve the above-mentioned purpose of the invention, the technical solution adopted by the present utility model is:

[0007] A highly stable weighing device for food quality inspection comprises: an electronic scale body, a weighing sensor protruding from the surface provided at the top center, a measuring plate provided at the top of the electronic scale body, the measuring plate being in contact with the weighing sensor in an unstressed state; a support assembly provided at the corners of the bottom of the electronic scale body, the support assembly being used to independently adjust the height of each corner of the electronic scale body; and a universal assembly provided within the support assembly, the universal assembly being used to adjust the angle of the support assembly to adapt to inclined support.

[0008] By setting up a support assembly that can independently adjust each corner and arranging a universal assembly on the support assembly, the angle of the support assembly can be adjusted. When encountering an uneven ground or table, leveling is performed by adjusting the height of the support assembly at the corresponding corner. The universal assembly rotates when the support assembly contacts the uneven ground or table, so that the support assembly can better fit the ground or table, which can improve the stability of the weighing instrument.

[0009] It is further defined that guide rods are vertically provided at the top corners of the electronic scale body, and guide cylinders matching the guide rods are provided at the bottom corners of the measuring disc. The outer diameter of the guide rod matches the inner diameter of the guide cylinder. When the measuring disc contacts the weighing sensor in an unstressed state, there is a gap between the top of the guide rod and the top of the inner hole of the guide cylinder. Arranging guide rods at the top corners of the electronic scale body and corresponding guide cylinders at the bottom of the measuring disc can prevent the measuring disc from tilting due to uneven sample distribution during the weighing process.

[0010] The lifting mechanism is configured to be connected to a base frame, and the base frame is connected to the support frame by a threaded connection to the bottom frame of the lifting mechanism. The lifting mechanism is configured to be connected to the support frame by a threaded connection to the bottom frame of the lifting mechanism. The lifting mechanism is connected to the support frame by a threaded connection to the bottom frame of the lifting mechanism. The lifting mechanism is connected to the support frame by a threaded connection to the bottom frame of the lifting mechanism.

[0011] It is further defined that the limit assembly includes a limit bar and a limit groove. The limit bar is arranged on the circumferential surface of the lifting cylinder along the axial direction of the lifting cylinder, and the limit groove is opened on the bottom surface of the supporting shell corresponding to the limit bar. The limit is achieved by setting the limit bar and the limit bar, the structure is simple, and the production is convenient.

[0012] It is further defined that the universal joint assembly includes a universal ball and a universal seat. The universal ball is fixed at the bottom of the lifting cylinder, the universal seat is fixed at the top of the supporting leg, and the universal ball is clamped in the universal seat. The angle of the supporting leg is adjusted by rotating the universal ball in the universal seat. The adjustment can be completed through contact, which is quicker and more convenient.

[0013] It is further defined that the supporting foot is in the shape of a suction cup and is deformable; setting the supporting foot in the shape of a suction cup and being deformable can achieve better fit to the inclined surface or curved surface and improve stability.

[0014] It is further defined that a spirit level is embedded on the central outer wall of the measuring disk; by embedding the spirit level on the central outer wall of the measuring disk, the adjustment result can be directly observed through the spirit level, thereby improving the leveling efficiency.

[0015] The beneficial effects of the utility model are as follows: by setting a support component with adjustable height and angle, the stability of the weighing instrument on an uneven surface can be improved, the support component can better fit the surface and is not easy to shake, and the structure is simple and easy to use.
