With the accelerating pace of life, the demand for the preservation and consumption of pre-treated foods and fresh foods is gradually increasing, and the demand for antibacterial preservative films required for fresh foods is also increasing. As a kind of polymer antibacterial material, polyoxometalates have been widely used in industrial catalysis, chemical pharmaceuticals, and antibacterial and antiviral products, and their antibacterial and antivirus effects are also widely applied in food packaging.

[0003] At present, the preparation of polyoxometalate antibacterial films for experiments mainly relies on manual paving.

Detailed implementation manners

[0021] As Figure 1 and Figure 2 shown, an antibacterial film preparation device, its main structure is composed of a spraying and spreading system, a vibration film forming system, a temperature control and drying system, etc.

[0022] The spraying and spreading system includes a lower box body 15, a longitudinal guide beam 6, a transverse guide beam 3, a spraying device 7 and a raw material bin 8. The upper end of the lower box body 15 is detachably provided with an upper box body 20.

[0023] The spraying device 7 is slidably arranged on the lower box body 15 through the longitudinal guide beam 6 and the transverse guide beam 3. A longitudinal toothed track 1 is arranged on the upper edge of the lower box body 15. The transverse guide beam 3 drives the spraying device 7 to move longitudinally along the longitudinal guide beam 6 through the longitudinal drive motor 2 and the longitudinal drive gear 11. A transverse toothed track 4 is arranged on the upper edge of the lower box body 15. The longitudinal guide beam 6 drives the spraying device 7 to move transversely along the transverse guide beam 3 through the transverse drive motor 12 and the transverse drive gear 5.

[0024] The upper end of the spraying device 7 is provided with a raw material bin 8. A forming plate 17 cooperating with the spraying device 7 is arranged in the lower box body 15. The forming plate 17 is matched with the opening on the side wall of the lower box body 15 through a support pulley 18. A push-pull handle is arranged on the front end face of the forming plate 17.

[0025] A stirrer 9 and a pressure device 10 are arranged in the raw material bin 8.

[0026] The vibration film forming system includes an electromagnetic oscillator 23. The boundary of the forming plate 17 is connected to the electromagnetic oscillator 23 in the lower box body 15.

[0027] During the paving process of the antibacterial film, the film forming plate 17 is in a vibrating state. In this way, the viscous resistance of the forming plate 17 can be used to make the film forming process reciprocate, so as to make the paving of the film-making composite liquid uniform, improve the quality of the antibacterial film. At the same time, in order to improve the film-making efficiency during the solution paving process, the rear of the forming plate 17 is heated by the electric control heater 21, and the upper fan 22 circulation system can also be used for accelerated drying, so that the biological antibacterial film dries quickly to achieve the test purpose.

[0028] Furthermore, the temperature control drying system includes a heater 21 and a fan 22. The heater 21 and the fan 22 that cooperate with the forming plate 17 are arranged on the rear end face of the lower box body 15.

[0029] A control screen 16, a temperature sensor 13 and a humidity sensor 14 are arranged on the front end face of the lower box body 15.

[0030] Rollers 19 are arranged at the bottom end of the lower box body 15.

[0031] The antibacterial film preparation device of the utility model is used for sample preparation according to the preparation process of the polyoxometalate antibacterial film and the characteristics of the antibacterial film. The polyoxometalate antibacterial material is sprayed and paved on the forming plate 17 by pressure spraying. By controlling different process parameters, the antibacterial film of the required specifications is prepared, providing a material sample for the antibacterial film characteristic test. Through the optimization of the antibacterial film preparation process parameters, a packaging film with uniform distribution of antibacterial substances and good light transmittance is obtained, providing important process control parameters for the industrial production of antibacterial films.

[0032] When the antibacterial film preparation device works:

[0033] The antibacterial film raw materials are placed in the raw material bin 8 and homogenized under the stirring of the stirrer 9. The antibacterial raw materials in the raw material bin 8 are sprayed on the forming plate 17 through the ejector device 7 by the pressure intensifier 10;

[0034] The ejector device 7 is fixedly installed crosswise with the transverse guide beam 3 and the longitudinal guide beam 6. The longitudinal driving gear 11 on the opposite side is synchronously driven by the longitudinal driving motor 2 to move longitudinally along the longitudinal tooth-shaped track 1, so as to realize the longitudinal movement of the raw material bin 8. The transverse driving gear 5 on the opposite side is synchronously driven by the transverse driving motor 12 to move transversely along the transverse tooth-shaped track 4, so as to realize the transverse movement of the raw material bin 8. Through the coordinated movement in the transverse and longitudinal directions, the ejector device 7 at the lower part of the raw material bin 8 sprays the antibacterial film raw materials onto the forming plate 17 for paving the antibacterial film;

[0035] The forming plate 17 is installed on the front end face of the lower box body 15 in a pull-out manner through the support pulleys 18. At the same time, the inner boundary of the forming plate 17 is connected to the electromagnetic oscillator 23 on the lower box body 15. During the spraying and paving process, the forming plate 17 can perform small reciprocating movements through electromagnetic vibration, promoting the uniformity of the antibacterial film thickness and removing small air bubbles in the film.

[0036] The heater 21 dries the antibacterial film that has been sprayed and paved on the forming plate 17 by means of the fan 22 with hot air, and discharges the wet air in the device through the exhaust port on the upper box body 20, accelerating the drying speed of the antibacterial film.

[0037] The temperature sensor 13 and humidity sensor 14 in the device monitor the working states of the heater 21 and the fan 22, controlling the internal environment of the forming device. At the same time, the information of the temperature sensor 13 and humidity sensor 14 is displayed on the control screen 16 at the front end of the device. After the antibacterial film is heated and dried, the forming plate 17 is taken out, and the antibacterial film is removed and made into test samples for research as needed.
