Description

Technical Field

[0001] The invention relates to the technical field of food processing, and in particular to automatic conveying equipment used for food processing. Background Art

[0002] In the food processing industry, automated conveying equipment is a key component for achieving efficient production. These devices are responsible for transporting raw materials, semi-finished products or finished products from one production link to another, ensuring the continuity and efficiency of the production process. As consumers' requirements for food safety and hygiene increase, food processing companies are paying more and more attention to dust control and hygiene management during the production process.

[0003] Existing automatic conveying equipment for food processing usually uses dust covers and dust suction devices to control dust diffusion when conveying powdered food. However, these dust suction devices are usually fixed on the dust covers at equal intervals. The suction force is concentrated, resulting in uneven suction in different areas. Some dust may remain on the conveying equipment or the dust cover, which is prone to dust accumulation, which not only affects the production environment, but may also breed bacteria due to long-term accumulation, affecting food safety.

[0056] Beneficial effects of the present invention:

[0057] 1. When the dust cleaning and collecting mechanism moves to one side, the scraper blade 1 in the forward direction will be expanded by the rebound of the coil spring, and the scraper blade 2 will be used to clean the inner wall of the conveying unit. The scraper blade 1 on the other side is pulled by one end of the slider and adheres to the inner wall of the conveying unit to further clean the inner wall to prevent residual dust from adhering to the inner wall and falling on the food due to shaking, which will affect food safety. It effectively improves the food hygiene quality and cleaning quality during transportation.

[0058] 2. Driven by the air pump, suction is generated in one circular hole. When the accumulated dust falls, it will be sucked in and slide along the slope of the inclined block to the second circular hole. The No. 2 motor drives the threaded rod to rotate, and the accumulated dust in the second circular hole is discharged into the dust collecting trough along the discharge hole. This structure can not only collect the scraped dust to prevent it from falling into the conveying unit and affecting the conveying hygiene, but also can adsorb the position with less suction around the dust collection unit, effectively improving the dust collection quality and avoiding dust overflow.

[0059] 3. The silica gel plate will adhere to the dust on the path, and the unadhered dust will pass through the circular holes and be concentrated, which is convenient for the dust collection unit to collect. The dual-axis motor can drive the frame to flip and adjust the distance between one end of the frame and the conveyor belt of the conveying unit to ensure that the food can pass through while maximizing the contact area with the dust, effectively improving the dust adhesion rate, and at the same time, it can adhere to the dust at the position where the suction force of the dust collection unit is relatively small to reduce dust diffusion.
