Description

Technical Field

[0001] This utility model relates to a filling device for food processing, belonging to the technical field of food processing equipment. Background Technology

[0002] In the food processing industry, the filling of powder products has long faced severe challenges. Due to their high fluidity and tendency to drift, powder products easily generate dust during traditional filling processes. This dust not only severely pollutes the production environment, leading to a decline in air quality within the workshop, but can also enter the human body through the respiratory tract, causing respiratory diseases and other health problems, endangering the health of operators. Furthermore, once the dispersed dust adheres to equipment surfaces, it increases the difficulty and cost of equipment cleaning and maintenance, and may also contaminate other batches of products, affecting food quality and safety.

[0003] Existing filling equipment typically lacks an effective sealing structure, making it difficult to reliably seal the can opening during filling. This leads to significant dust leakage and dispersion. Furthermore, most traditional equipment involves cumbersome adjustments when dealing with cans of different sizes, often requiring the replacement of specialized parts, which greatly limits production efficiency. In addition, with increasingly stringent environmental policies, the dust pollution from traditional filling equipment is no longer sufficient to meet the requirements of modern food processing industries for green and safe production. There is an urgent need to design a filling device with efficient sealing and a wide range of size adaptability to improve the safety, stability, and versatility of food filling production. Utility Model Content

The airbag 105 has a circular structure and is sleeved on the lower end of the sliding bushing 104. The airbag 105 is fixedly connected to the bottom of the airbag mounting plate 10402. Because the powder product has good flowability and is easy to drift, the powder product is prone to generating dust when filling the product can. Dust can easily cause harm to the human body and affect human health. Therefore, an airbag 105 is set on the powder can 101. The airbag 105 is used to seal the product can during the filling process, thereby reducing dust leakage and diffusion, and protecting the production environment and human health.

[0033] The bottom of the sliding bushing 104 includes a switch mounting hole 10403, a tapered opening 10401, a linkage groove 10405, and a sensor 10404, which are arranged opposite to each other.

The adjustment bracket 202 is fixed to the belt conveyor 2. One end of the adjustment bolt 203 is threadedly connected to the adjustment bracket 202, and the other end is threadedly connected to the adjustment plate 201. By rotating the adjustment bolt 203, the size adjustment devices move relative to or towards each other on the adjustment bracket 202, thereby adjusting the distance between the size adjustment devices to accommodate product cans of different sizes. The belt conveyor 2 is driven by a motor that rotates the belt. A certain gap is provided between the adjustment plate 201 and the belt of the belt conveyor 2 to prevent the adjustment plate 201 from obstructing the belt movement.

[0038] A filling device for food processing according to this application includes a control system, which can be a PLC control system. Sensors 10404, pressure gauges 108, first power components 106, second power components 10701, and third power components 1010 are all electrically connected to the control system.

[0039] The working process of a food processing filling device according to this application is as follows:

[0040] 1) The product can is placed between the size adjustment devices with the spacing adjusted, and the belt conveyor 2 transports the product can towards the powder bucket 101. When the sensor 10404 detects that the product can is directly below the powder bucket 101, the belt conveyor 2 stops moving.

[0041] 2) The first power component 106 drives the sliding bushing 104 to slide downward. When the sensor 10404 detects that the relative position between the product and the sliding bushing 104 reaches a preset height, the first power component 106 stops moving.

[0042] 3) The second power component 10701 drives the upper telescopic rod 10702 and the lower telescopic rod 10703 to move, so that the upper telescopic rod through hole 10706 of the upper telescopic rod 10702 is aligned and connected with the air intake channel 10707, and the lower telescopic rod 10703 blocks the vent hole 10705. The airbag power device 107 connects to the air source, and compressed air enters the airbag 105 through the air intake channel 10707. The airbag gradually increases in size until it comes into contact with the opening of the product can, sealing the opening of the product can. The pressure sensor 108 detects that the pressure in the air intake channel 10707 has reached the preset value, and the air source is disconnected. Since the airbag 105 is fixed on the airbag mounting plate 10402, and the airbag mounting plate 10402 is a rigid component, the airbag can only expand vertically downward and horizontally when it increases in size.

[0043] 4) During the process of airbag 105 increasing, airbag 105 presses against the linkage plate 101301 of switch 1013, thereby driving switch 1013 to move downward, so that switch 1013 separates from discharge port 10101, and the powder product in powder bucket 101 is filled into product tank. During the filling process, the sealing effect of airbag 105 greatly reduces the dust generated by powder product.

[0044] 5) When sensor 10404 detects that the powder product in the product can has reached the preset height, the second power component 10701 drives the upper telescopic rod 10702 and the lower telescopic rod 10703 to move, so that the lower telescopic rod 10703 separates from the vent hole 10705, the gas in the air bag 105 is discharged through the vent hole 10705, the air bag 105 separates from the product can, the switch component 1013 is reset under the action of the reset spring 1012, and the discharge port 10101 is blocked again. The second power component 10701 drives the sealing component to reset upward, and the filled product can is transported to the next station by the belt conveyor 2.

[0045] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
