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
Present technique relates to controlled atmosphere fresh-keeping packing machine, specifically, is a kind of transmission device of controlled atmosphere fresh-keeping packing machine.
Background technology
Because desk-top controlled atmosphere fresh-keeping packing machine volume is little; Domestic similar product major part all adopts manually and seals at present, and the self-sealing mechanism of ability is complicated, and the results in machines external form is difficult to mate transmission device; Cause outward appearance not attractive in appearance; The transmission device maintenance difficult, defective such as sealing effect is undesirable, and volume is bigger.
Summary of the invention
The purpose of present technique provides a kind of transmission device that can drive the controlled atmosphere fresh-keeping packing machine that vacuum chamber parallelly up and down moves, sealing effect is good, volume is little, simple in structure.
The transmission device of this controlled atmosphere fresh-keeping packing machine; Comprise rotating and be arranged on the screw rod that links to each other on the frame, with actuating unit; Has the opposite positive minus thread of hand of spiral on the screw rod; Two nuts respectively with positive and negative screw thread fit, the two ends of arbitrary connecting rod in two connecting rods are hinged with a nut and last vacuum chamber respectively; Positive minus thread, two nuts, two connecting rods are all with following plane of symmetry symmetry: the said plane of symmetry is perpendicular to screw rod and passes through the plane of positive minus thread linking part.
The beneficial effect of present technique: drive screw rod through actuating unit and rotate, be positioned at two nuts on the screw rod promptly do each other near or each other away from move, through two connecting rods, can drive (on) vacuum chamber moves up and down.Because positive minus thread, two nuts, two connecting rods so vacuum chamber can be not crooked in the process of moving up and down, have guaranteed seal quality all with plane of symmetry symmetry.Present technique has reached with simple structure and driven vacuum chamber parallel mobile purpose up and down, and is reliable, with low cost.
Described transmission device, positive minus thread is Acme thread.
Described transmission device, actuating unit are the worm and gear reducing motor.
Description of drawings
Fig. 1 is the scheme drawing of the desktop electric controlled atmosphere fresh-keeping packing machine of present technique.
Fig. 2 is the scheme drawing of the transmission device among Fig. 1.
The specific embodiment
Referring to Fig. 1, shown in 2; The transmission device of desktop electric controlled atmosphere machine; Comprise through 5 rotations of outer goal rolling bearing units being arranged on the positive and negative trapezoidal screw 2 that links to each other on the frame 6, with worm and gear reducing motor 1, have the opposite positive and negative Acme thread of hand of spiral on the screw rod.Right handed unt 3, left-handed nut 4 cooperate with positive and negative Acme thread respectively.Right handed unt 3 is hinged through two connecting rods 71 and pressing plate 8, and left-handed nut 4 is hinged through two connecting rods 72 and pressing plate 8, and the two ends, bottom of pressing plate 8 respectively join through depression bar 9 and last vacuum chamber 14.Pitman shaft 15 and pressing plate are passed through respectively in the two ends of connecting rod, nut is hinged.Positive and negative Acme thread, connecting rod 71 and connecting rod 72, right handed unt 3 and left-handed nut are all with following plane of symmetry symmetry: the said plane of symmetry is perpendicular to screw rod and passes through the plane of positive minus thread linking part.
This structure is by the worm and gear reducing motor, coaxial positive and negative trapezoidal screw and nut, composition such as spherical outside surface rolling bearing units, four connecting rods and pressing plate; When the worm and gear reducing motor is worked; Drive coaxial positive and negative screw drive, positive and negative nut locking phase to or opposite moving, drive pressing plate through connecting rod; Pressing plate drive upward vacuum chamber is steadily gone up and down, and promptly realizes the transmission packaging process of machine.
