the working principle of the sealing machine
the working principle of the sealing machine: its working principle is simpler and easier to understａnd than those of larger packaging equipment such as shrinking machines. when the package containing the heat-shrinkable film is placed on the heat-sealing film conveyor belt, the sealing part of the bag is automatically sent between the two sealing belts running the heat-shrinking gun and brought into the heating zone, and the heat of the heating block is transmitted through the sealing belt to the sealing part of the bag, the film is heated and softened, and then through the cooling zone, the surface temperature of the film is appropriately lowered, and then it is rolled by the knurling wheel or the printing wheel, so that the upper and lower plastic films of the sealing part are bonded and pressed into a net pattern or the logo is printed, and the sealed packaging bag is sent out of the machine by the guiding rubber belt and the conveyor belt, and the sealing machine completes the sealing.
the assembly part of the sealing machine is composed of a frame, a transmission mechanism for slowing down and speed regulation, a printing mechanism during sealing, a conveying device and an electrical and electronic control system. after the sealing machine is connected to the power supply, each mechanism can start to work. the electric heating element is heated by electricity, so that the temperature of the upper and lower heating parts rises sharply. the temperature can be controlled to adjust the system to the required temperature. the impression wheel rotates according to the cooling system needs to start cooling, and the conveyor belt is transferred and adjusted to the required speed by the speed control device. the sealing machine adopts electronic optional precision temperature controller, sealing and printing are automatically completed at one time, and can seal any kind of heatable film. the sealing machine is the development and application of modern technology. it is easy to operate and uses delicate ptfe-coated sealing tape. nowadays, whether it is heat-sealing film food, cosmetics, clothing and shoes, or heat-sealing film chemicals, electrical appliances, medicine, tea, dairy, beverages and other fields, with the development of the times, the wide application of sealing machines has been the market is getting more and more attention.
