Embodiment Construction

[0010] see figure 1 , 2 As shown, the transmission mechanism of the table-top electric controlled atmosphere fresh-keeping machine includes a positive and negative trapezoidal screw 2 which is arranged on the frame 6 through the rotation of the outer ball bearing 5 and is connected with the worm gear motor 1. The screw has opposite helical direction Positive and negative trapezoidal thread. The right-handed nut 3 and the left-handed nut 4 cooperate with the positive and negative trapezoidal threads respectively. The right-handed nut 3 is hinged with the pressing plate 8 through two connecting rods 71, the left-handed nut 4 is hinged with the pressing plate 8 through two connecting rods 72, and the lower two ends of the pressing plate 8 are respectively connected with the upper vacuum chamber 14 through the pressing rod 9. The two ends of connecting rod are hinged with pressing plate and nut respectively by connecting rod shaft 15. The positive and negative trapezoidal threa...

Abstract

The invention aims at providing a transmission mechanism of a modified atmosphere fresh-keeping packaging machine, which can drive an upper vacuum chamber and a lower vacuum chamber to move in parallel and has good sealing effect, small size and simple structure. The transmission mechanism comprises a screw rod rotatably arranged on a stand and connected with a power mechanism, the screw rod is provided with positive and negative threads with opposite spiral directions, two nuts are respectively matched with the positive and negative threads, both ends of any one of two connecting rods are respectively hinged with one nut and the upper vacuum chamber; the positive and negative threads, the two nuts and the two connecting rods are symmetrical in relative to the following plane of symmetry; and the plane of symmetry is a plane perpendicular to the screw rod and passing by the jointing part of the positive and negative threads.

Description

technical field [0001] The technology relates to a modified atmosphere fresh-keeping packaging machine, specifically, a transmission mechanism of a modified atmosphere fresh-keeping packaging machine. Background technique [0002] Due to the small size of the desktop modified atmosphere fresh-keeping packaging machine, most of the similar products in China currently use manual sealing, and the automatic sealing mechanism is complicated, which makes it difficult for the appearance of the machine to match the transmission mechanism. The effect is not ideal, the volume is large and other defects. Contents of the invention [0003] The purpose of this technology is to provide a transmission mechanism of a modified atmosphere fresh-keeping packaging machine that can drive the vacuum chamber to move up and down in parallel, has good sealing effect, small volume and simple structure. [0004] The transmission mechanism of this modified atmosphere fresh-keeping packaging machine ...
