The sealing machine is also a packaging machine. The sealing machine is composed of a frame, a speed reduction transmission mechanism, a sealing printing mechanism, a conveying device and an electrical and electronic control system. When the power is turned on, each mechanism starts to work, and the heating element is heated after being energized, so that the upper and lower heating blocks are heated up sharply, and the temperature is controlled to the required temperature by the temperature control system, the printing wheel rotates, and the cooling system starts to cool as needed, and the conveyor belt is sent, And adjusted by the speed control device to the required speed.
When the package containing the article is placed on the conveyor belt, the sealing portion of the bag of the sealing machine is automatically fed between the two sealing tapes in operation and brought into the heating zone, and the heat of the heating block is transmitted to the bag through the sealing tape. The sealing part is such that the film is melted by heat, and then passes through the cooling zone to appropriately lower the surface temperature of the film, and then is rolled by a knurling wheel (or a printing wheel) to bond the upper and lower plastic films of the sealing part and press the mesh pattern (or Printing the mark), and then the sealed bag is sent out of the machine by the guiding rubber belt and the conveyor belt to complete the sealing operation.
The first step of the sealing machine operation process is to seal the machine - wear the film, get the film to confirm the winding direction of the film, find the counterclockwise direction, and put it on the film rod to fix it. Please turn off the power), pay attention to whether the front and rear fixing plates of the film are tightly combined with the film. If it cannot be tightly combined, use a utility knife to cut the inside of the film tube and then insert it. After wearing the film, use glue to glue the film. The film is firmly attached to the receiving paper tube.
The second step begins the sealing operation. The sealing machine is powered on, the power switch is turned on, the indicator light is on, the temperature controller is set to the predetermined temperature, and the green heating indicator is on. When the upper hot plate reaches the predetermined temperature, the red constant temperature indicator light is on (the sealing device is alternately in the heating and heat preservation state during the work and the process, so the green and red indicator lights are alternately displayed, which is a normal phenomenon).
Put the plastic cup into the lower mold slide and push the lower mold slide to the determined position by hand (if it is a fully automatic sealing machine or automatic sealing machine, after placing the plastic cup, the lower mold slide will automatically enter), press down Seal the handle of the machine to the maximum stroke, hold it for 1~2 seconds, then slowly raise the handle and push it to the original position.
For a dieboard slide; take out the cup and place it in the final seal cup and then perform another cycle to bring the cup to temperature and condition.
After understanding the working principle and operation method of the sealing machine, it is very convenient when used, and saves a lot of unnecessary troubles.
