What is the Solution to the Displacement of the Vacuum Packaging Machine?

What's the matter with people shifting when they use the vacuum packaging machine? The following editor will introduce the solution to the displacement of the vacuum packaging machine.

There are two kinds of commonly used single-chamber and double-chamber. The single-chamber is a flat-panel type. There are two sets of support frames on the rear side of the upper and lower vacuum systems. There is a long shaft with double torsion springs in the middle, which is balanced by the double torsion springs. The interaction force opens the viewing angle of 45-75 degrees.

The double chamber is reciprocating. The lower vacuum system is divided into two upper and lower working rooms. The upper vacuum system is offset up and down by the support points of the four crankshafts. The four crankshafts are fixed on the two long shafts. There are tension spring forks on the long shafts. , The lower side of the two tension springs is fixed on the sound card rack, and the upper end is fixed on the tension spring fork, which has the effect of balancing the actual operating force. The two long shafts are precisely positioned by two sets of seated bearings. Four The upper end of the crankshaft is also inlaid with a miniature bearing, so the up and down shift is very light and easy. The vacuum pump starts up with a slight working pressure, and it can be opened automatically after the air return is completed.

The support points are offset from the four connecting rods of the upper vacuum system. The front and rear, left and right sides of each long axis must be parallel. The upper and lower crankshafts should also be relatively parallel to ensure that the upper vacuum system is in all parts of the upper and lower parts. Keep parallel surfaces with the lower vacuum system. Otherwise, the upper and lower vacuum systems cannot maintain parallel surfaces, and the actual operating pressure will increase significantly. When it is more serious, it is impossible to create a vacuum pump normally.
