Description

Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a weighing device for solid food detection. Background Art

[0002] The weight detection of existing solid food production lines generally adopts a separate workstation design. The staff needs to perform weight detection on the food individually, or adopt a random sampling method. In this method, the staff needs to place the products one by one on the scale for weighing, which reduces the efficiency of food detection.

[0003] A Chinese patent discloses a weighing device for solid food detection (authorization announcement number CN211205468U). The patent technology is provided with transmission components on both sides of the box. When the user performs weight detection on the solid food, first, the solid food is transmitted to the weighing component through the first transmission component, and the weight of the solid food is known by the operation of the weighing component. Secondly, the solid food is pushed into the second transmission component by the operation of the pushing component, and the solid food is transmitted to the corresponding equipment by the second transmission component, thereby improving the efficiency of the solid food weight detection; however, it has certain disadvantages: it transmits the solid food to the supporting plate through the first transmission component, and the falling position of the solid food is at the right end of the first transmission component, which is fixed, and the position of the bearing plate is also fixed, which makes it easy for the solid food to overlap when it falls on the bearing plate, so that it falls on the ground, or falls to the edge of the bearing plate, which makes it easy for the pushing component to push a part of the solid food from the front and rear edges of the bearing plate when pushing the solid food, and it is impossible to ensure that all the solid food is pushed onto the second transmission component.

[0023] The solid food 24 is transported from right to left through the conveyor belt 1. The two baffles 2 are very close to the belt of the conveyor belt 1, but do not touch it, so as to limit the solid food 24 and prevent it from deviating due to the vibration of the conveyor belt 1. The slide plate 4 and the two baffles 2 are detachably connected, such as bolted, so that when the spacing between the baffles 2 changes, it is convenient to replace slide plates 4 of different specifications.

[0025] The distance between the two baffles 2 can be adjusted by moving the adjustment rod 23 in the adjustment seat 21 to be suitable for solid foods 24 of different specifications.

[0026] The working principle of the utility model is as follows: when in use, the solid food 24 moves from the right end to the left end of the conveyor belt 1, and falls into a support box 10 through the slide plate 4. The photoelectric sensor 5 detects that the solid food 24 passes through. After a delay of several seconds, the motor 13 drives the threaded rod 14 to rotate, and the displacement block 15 threadedly connected to the threaded rod 14 drives another support box 10 to move to the bottom of the slide plate 4; when all the support boxes 10 are filled, the weighing sensor 8 transmits the detected weight data, and then the electromagnet 19 is powered off, the movable plate 17 is opened, and the solid food 24 falls.
