Structure.
Background technique
Double-chamber vacuum machine is a kind of single-chamber room, and chamber can be because of the vacuum packing machine of vacuum chamber lid or so parallel rotation；
Product to be packaged is loaded by one side, is vacuum-packed on one side, Lai Tigao production efficiency, reach single-chamber vacuum packaging machine two are efficiency-timed
Rate.And have benefited from flat platform, it is also very convenient to clean.
Past, transmission double-chamber vacuum machine need to lift vacuum chamber lid using manpower, are moved into another side to start
Vacuum packaging.And after machine dimensions become larger, some lids needs are excessive compared with great strength or moving distance, are unfavorable for manually grasping
Make, reduces production efficiency.So also just there is semi-automatic double-chamber vacuum machine.Semi-automatic double-chamber vacuum machine only needs button press,
Vacuum chamber lid can rise automatically and be moved to another side.
But pneumatic structure used by traditional semi-automatic vacuum machine is all that a cylinder controls a direction, a drawing is arrived
Bottom, when vacuum chamber is built, cylinder pulling force overcomes vacuum chamber lid gravity, moreover it is possible to make its stable rotation, but surely under cavity cap
When drop, cylinder pulling force added the gravity of vacuum chamber lid, so that its decline is rapidly, cover suddenly, have security risk, and prominent
The vacuum chamber being so closed can also allow the internal vacuum bag for having put good position to be blown, to influence packaging quality.

Embodiment
As shown in Figures 1 to 7, the pneumatic gearing structure of automatic double-chamber vacuum machine, including vacuum platform 1 and be located at described
The vacuum chamber lid 2 on 1 top of vacuum platform, the left side of the vacuum chamber lid 2 are hinged with left front upper swing arm 31, left back upper swing arm 32,
The right side of the vacuum chamber lid 2 is hinged with upper swing arm 34 behind right front upper swing arm 33, the right side, left front upper swing arm 31, right front upper swing arm 33
Be fixedly connected respectively with rotational installation in the front rotary shaft 51 on vacuum platform 1, left back upper swing arm 32, it is right after upper swing arm 34 respectively with
It is rotatablely installed and is fixedly connected in the rear shaft 52 on vacuum platform 1, front rotary shaft, rear shaft are respectively by being mounted on vacuum platform two
The bearing block of side is installed；Upper swing arm 34, which is parallel to each other, behind left front upper swing arm 31, left back upper swing arm 32, right front upper swing arm 33, the right side sets
It sets, so that vacuum chamber lid 2 can be relative to 1 front and back parallel rotating motion of vacuum platform；Left front upper swing arm 31, left back upper swing arm
32, the spacing shim 6 that slides axially is respectively arranged between upper swing arm 34 and vacuum platform 1 behind right front upper swing arm 33, the right side, with fixation
The firmly spacing between each upper swing arm and platform；
With reference to Fig. 2, the left and right sides of the vacuum platform 1 is respectively disposed with a driving cylinder 4, the driving of the left and right sides
Cylinder 4 arranges that the compression chamber 41 of the driving cylinder 4 is connected with scavenging air valve and pressure reducing valve, the scavenging air valve of cylinder in reverse symmetry
Known common components can be used with pressure reducing valve, is not shown in the figure and is no longer described in detail；
With reference to Fig. 3, the front end of the left side driving cylinder 4 is hinged with left front lower swing arm 35, the left front lower swing arm 35 with
51 left end of front rotary shaft is fixedly connected, and the angle between the left front lower swing arm 35 and the left front upper swing arm 31 is a1；Left side institute
The rear end for stating driving cylinder is hinged with left back lower swing arm 36, and the left back lower swing arm 36 is fixedly connected with rear 52 left end of shaft, institute
The angle stated between left back lower swing arm 36 and the left back upper swing arm 32 is b1；Wherein, a1、b1It is obtuse angle, and a1≠b1, i.e.,
a1、b1With deviation；
The front end of the right side driving cylinder 4 is hinged with right front lower swing arm 37, the right front lower swing arm 37 and front rotary shaft 51
Right end is fixedly connected, and the angle between the right front lower swing arm 37 and the right front upper swing arm 33 is a2(not shown)；It is right
The rear end of cylinder is driven to be hinged with lower swing arm 38 behind the right side described in side, lower swing arm 38 and the fixed company of rear 52 right end of shaft behind the right side
Connect, it is described it is right after lower swing arm and it is described it is right after angle between upper swing arm be b2(not shown)；Wherein, a2=b1、b2=a1。
The angle and the degree of deviation of a1, b1 can according to the difference of type length flexible setting, but to guarantee that a1, b1 are obtuse angle, and
A1 ≠ b1 is reached at travel compression minimum with realizing that two sides cylinder is non-concurrent.
With reference to fig. 4 to fig. 6, vacuum chamber lid by vacuum platform front end backward end motion when, along the direction of motion, when left front upper pendulum
When angle between arm 31 and vacuum platform 1 is c (being 85 ° in the present embodiment), the left side driving cylinder reaches travel compression
At minimum；Since the driving cylinder of the left and right sides is arranged in reverse symmetry, and a2=b1、b2=a1, when left front upper swing arm and vacuum
When angle between platform is 95 °, the right side driving cylinder reaches at travel compression minimum.Certainly, angle c may be it
His angle.
Termination is installed on the front rotary shaft and touches piece 71 and swings and touches piece 72, be equipped on the vacuum platform 1 with
The swing limit switch of the cooperation of piece 72 is touched with the finishing limit switch 81 for terminating the touch cooperation of piece 71, with the swing
82, the closed position and intermediate swing that can monitor vacuum chamber lid respectively depressurize position of losing heart.
Referring again to fig. 4 to fig. 6, working principle is as follows: the driving cylinder symmetrical reverse installation of left and right two, ipsilateral to connect with cylinder
Angle deviation certain angle between the lower swing arm and upper swing arm connect.Surely when cavity is pressed against platform side, the compression chamber of cylinder
41 air inlets, two cylinder stroke synchronous drive vacuum chamber lid 2 to rotate so that upper swing arm rotates.Due to angular displacement, this reality
It applies in example, (see Fig. 5) when vacuum chamber lid turns to 85 °, a cylinder reaches at travel compression minimum, but another cylinder is also
Not up to, resultant moment still will be another (see Fig. 6) when last vacuum chamber lid rotates more than 95 ° so that vacuum chamber lid continues to rotate
A cylinder also reaches at travel compression minimum, at this moment by scavenging air valve and pressure reducing valve, slows down the discharge of gas of compression chamber, to vacuum
Chamber lid declines the effect for foring damping, so that vacuum chamber lid slowly land.It is also same that vacuum chamber lid, which opens rotation from the other end,
The working principle of sample.
After vacuum cover closure, finishing limit switch receives signal, by PLC precompiler, carries out a series of vacuum
Packing work.Standby after the completion, after button press, automatic cover-turning completes vacuum packaging work.
The above descriptions are merely exemplary embodiments of the present utility model, the model being not intended to limit the utility model
It encloses.Any those skilled in the art, it is made under the premise of not departing from the conceptions and principles of the utility model to be equal
Variation and modification, should belong to the range of the utility model protection.
