Description

Technical Field

[0001] The present invention discloses a metal powder packaging sealing device and a method of using the same, and relates to a device and a method of using the same for automatically sealing a packaging bag for packaging metal powder, and belongs to the technical field of metal powder packaging, and particularly relates to a sealing device that can vibrate the packaging bag so that the metal powder at the bag opening falls to the bottom of the bag due to the vibration, and then is heated and sealed, so as to avoid the metal powder remaining at the bag opening, resulting in a loose seal. Background Art

[0002] After the metal powder is mixed, it needs to be packaged. After the metal powder is loaded into the packaging bag, in order to seal the metal powder and prevent it from leaking due to moisture, the bag mouth needs to be sealed. The traditional sealing method is to manually put the metal powder in a separate bag, and then clamp the bag mouth with an electric heating plate for heating and sealing. This method is labor-intensive and has low packaging efficiency. Currently, a packaging and sealing integrated machine is often used to package and seal the metal powder. The packaging and sealing machine uses a whole long packaging bag to pack the metal powder. After a certain amount of metal powder is loaded into the bag by a loading barrel, the packaging bag is heated and sealed by a sealing mechanism, and the sealed packaging bag is cut from the long packaging bag to form an independent package, thereby completing the packaging and sealing operation. However, due to the light weight of the metal powder, when filling the bag, the inner side of the bag mouth is easily stained with powder. When the bag mouth is heated and sealed, the powder retained at the bag mouth is likely to cause a gap in the bag mouth, resulting in a loose seal, which makes the metal powder easy to leak due to moisture, which is not conducive to the preservation of the metal powder.

The fixed electric heating plate cooperates with the mobile electric heating plate to increase the contact area with the bag mouth, so that the bag mouth fits more closely and the seal is more tight. ; 2. The method for using the metal powder packaging sealing device according to claim 1, characterized in that A group of positioning posts is arranged on the installation panel, and the group of positioning posts consists of four positioning posts, and the positioning posts are close to one side of the installation panel, one end of the positioning posts is connected to the installation panel, and the other end is not in contact with the vibration guide plate, and the four positioning posts correspond to four fixed springs one by one, and the fixed spring sleeves are arranged on the corresponding positioning posts, and the length of the positioning posts is smaller than the length of the corresponding fixed springs; the positioning posts can position the fixed springs, limit the displacement amplitude of the fixed springs subjected to vibration after the vibration motor is started, and ensure the stability of the vibration guide plate, so that the packaging bag can be smoothly moved down for heating and sealing.

3. The method for using the metal powder packaging sealing device according to claim 1, characterized in that The fixed electric heating plate is provided with a group of strip embossings, which consist of a plurality of strip embossings, and the plurality of strip embossings are equidistantly distributed along the length direction of the fixed electric heating plate; the movable electric heating plate is provided with a group of strip pressing grooves, which consist of a plurality of strip pressing grooves, and the plurality of strip pressing grooves are equidistantly distributed along the length direction of the movable electric heating plate, and the plurality of strip pressing grooves correspond to the plurality of strip embossings one by one; the strip embossings and the strip pressing grooves can increase the contact area with the bag opening, press the bag opening more tightly, and seal it more tightly.

4. The method for using the metal powder packaging sealing device according to claim 1, characterized in that The cutting knife groove is a V-shaped structure, and the width of the cutting knife groove gradually increases from the groove bottom to the groove mouth, which can guide the cutting knife and smoothly complete the cutting and separation of the sealed packaging bag.

5. The method for using the metal powder packaging sealing device according to claim 1, characterized in that The vibration guide plate cooperates with the vibration motor to vibrate the packaging bag filled with metal powder, so that the metal powder at the bag mouth falls to the bottom of the bag due to the vibration and then is heated and sealed, thereby preventing the metal powder from remaining at the bag mouth and causing a loose seal.
