Description

Technical Field

[0001] The utility model relates to the technical field of sealing machines, in particular to a continuous air extraction sealing machine. Background Art

[0002] Vacuum sealing machines are generally suitable for vacuuming, inflating, and fitting various foods, meat products, seafood, fruits and vegetables, pickles, chilled meat, pharmaceutical products, hardware components, medical equipment, etc. After the items to be packaged are evacuated, the packaging bag shrinks and some air (oxygen) in the packaging container is removed, which can effectively prevent the packaging from spoiling. The use of packaging materials with excellent barrier properties (air tightness) and strict sealing technology and requirements can effectively prevent the exchange of packaging contents, which can avoid food weight loss and taste loss, and prevent secondary pollution. The sealing machine often uses a printing wheel to print the production date on the packaging bag.

[0003] In the prior art, it is relatively complicated to replace the printing wheels of most sealing machines, which causes the operator to spend a lot of time during replacement, resulting in reduced work efficiency. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a continuous vacuum sealing machine to solve the above problems.

[0005] In view of this, the utility model provides a continuous vacuum sealing machine, including a sealing machine body, including:

[0006] The ink wheel is installed on the working end of the sealing machine body;

[0007] The printing wheel is installed on the working end of the sealing machine body, and the printing wheel includes a shell installed on the working end of the sealing machine body, a mounting groove arranged at the end of the shell away from the sealing machine body, a conflicting column arranged at the bottom of the mounting groove, a mounting column inserted in the mounting groove and conflicting with the conflicting column, a plurality of placement grooves arranged on the side wall of the mounting column, a plurality of moving holes arranged on the outer side of the shell, a fixed end installed in the plurality of placement grooves, a plurality of letter grains penetrating the moving holes at the printing end, and an opening and closing structure installed at the end of the shell away from the sealing machine body, the plurality of placement grooves are respectively arranged in a circumferential direction with the central axis of the mounting column, the plurality of moving holes are respectively arranged in a circumferential direction with the central axis of the shell, and the moving holes are all connected to the end of the shell away from the sealing machine body;

[0008] Among them, one end of the installation column facing away from the abutment column is flush with the notch of the installation groove, and the opening and closing structure is used to prevent the installation column from moving. When the opening and closing structure is installed, a number of the letter particles abut against the side wall of the movable hole facing the sealing machine body, and the fixed end of the letter particles is attached to the inner wall of the shell and the side wall of the placement groove facing away from the sealing machine body.

[0009] By adopting the above technical solution, when the type particles need to be installed, firstly, the fixed ends of several type particles are placed at the bottom of the placement groove, and then the installation columns are pushed into the installation grooves after aligning several type particles with the movable holes. When the installation columns are in conflict with the interference columns, the type particles are fixed by the interference, and finally the opening and closing structure is installed to complete the installation of the type particles, which greatly provides convenience for the operator. When the type particles need to be replaced, the opening and closing structure is removed, the installation columns are pulled out, and then the type particles are replaced. Finally, the above installation steps are performed for installation, which greatly provides convenience for the operator in replacing and installing the type particles.

[0010] Furthermore, the opening and closing structure includes:

[0011] A contact cover is contacted with a side of the shell facing away from the sealing machine body;

[0012] The thread groove is arranged on a side of the abutment block away from the bottom of the installation groove;
