Abstract
A kind of pneumatic sealing device and its encapsulating method, sealing installation panel are fixed on overhead door, and cylinder is fixed on sealing installation panel, and connecting plate is fixed on cylinder push-rod, and polyethylene strip and rubber weather strip are fixed by connecting plate.When overhead door is closed and machine is run, push sealing strip that sealing strip is pressed to another overhead door end face by cylinder, so as to fulfill sealing.When machine down, overhead door need to rise, cylinder is died, and compressed spring pushes the spring connecting rod being mounted on connecting plate to retract sealing strip, and sealing strip is made to be completely disengaged, then rise overhead door with another overhead door end face.The advantages and positive effects of the present invention are：Since sealing strip can realize that, compared with large deformation, sealing strip pressure can be adjusted by cylinder, can effectively eliminate seal clearance；The friction and impact between sealing strip and overhead door end face are avoided, effectively extends the service life of sealing device.
Description
Technical field
It is the present invention relates to tobacco machine, i.e., a kind of to the device of overhead door progress pneumostop outside cigarette making and tipping machine and its close
Encapsulation method.
Background technology
Cigarette making and tipping machine is the machine that runs at high speed for producing cigarette, and speed of production is high, and production environment noise is big, simultaneously
A large amount of subtle pipe tobacco dusts can be generated in process of production.So cigarette making and tipping machine outside need is close to machine progress by overhead door
Envelope, and end face needs to be sealed by sealing strip device between Men Yumen.Existing sealing strip device is using overhead door
One end pushes polyethylene sealing strip to press to another overhead door end face by multiple springs.Due to there is relative motion between Men Yumen,
It is larger that sealing material can only choose hardness, the smaller polythene material of deflection, and acting force of the spring is unequal on sealing strip,
So there is a situation where that polyethylene sealing strip is poorly sealed, lead to that cigarette making and tipping machine production work environmental noise is excessive, and dust is more.
And fricting movement can be generated between sealing strip and overhead door, in the course of time abrasion can be generated to sealing strip.Novel cigarette simultaneously
Unit overhead door is arc overhead door, there is a situation where that two end faces are completely disengaged between Men Yumen, then two recombine
When sealing strip and overhead door between can form impact, it is possible to damage sealing strip device.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide one kind can in cigarette making and tipping machine operational process it is close
Obturage effective sealing device and method of the sealing strip without friction and impact during close, overhead door rises.
This pneumatic sealing device includes rubber weather strip, polyethylene strip, connecting plate, cylinder, sealing installation panel, spring
Connecting rod, compressed spring.It is characterized in that：The pneumatic sealing device is sealing device to be pushed to realize sealing, sealing by cylinder
Installation panel is fixed on overhead door, and cylinder is fixed on sealing installation panel, and connecting plate is fixed on cylinder push-rod, Ran Houyou
Connecting plate fixes polyethylene strip and rubber weather strip.When overhead door is closed and machine is run, push sealing strip will be close by cylinder
Strip of paper used for sealing presses to another overhead door end face, so as to fulfill sealing.When machine down, overhead door need to rise, cylinder is died, compression
Spring pushes the spring connecting rod being mounted on connecting plate to retract sealing strip, makes sealing strip completely de- with another overhead door end face
From, then rise overhead door.
The number of cylinders is set according to the height of overhead door, is 2-5.
The spring connecting rod quantity is set according to the height of overhead door, is 2-15.
The advantages and positive effects of the present invention are：As a result of soft rubber weather strip, sealing strip can realize compared with
Large deformation, while sealing strip presses to the active force of overhead door end face and can be adjusted by cylinder, can effectively eliminate seal clearance；
And when overhead door rises, sealing strip can be fully disconnected with another overhead door end face, avoid sealing strip and overhead door end
Friction and impact between face effectively extend the service life of sealing device.
Description of the drawings
Fig. 1 is the structural front view of the embodiment of the present invention
Fig. 2 is I partial enlarged views
Fig. 3 is the dimensional structure diagram of the embodiment of the present invention
In figure：1- lifts door main body, 2- polyethylene strips, 3- rubber weather strips, 4- cylinders, 5- connecting plates, 6- sealings
Panel, 7- spring connecting rods, 8- compressed springs are installed.
Specific embodiment
The embodiment of the present invention is further described below in conjunction with the accompanying drawings.
In fig. 1-3, this pneumatic sealing device, including glue sealing strip 3, polyethylene strip 2, connecting plate 5, cylinder 4, sealing
Panel 6, spring connecting rod 7, compressed spring 8 are installed.Sealing installation panel 6 is mounted on lifting door main body 1, and cylinder 4 passes through spiral shell
Nail is mounted on sealing installation panel 6, and connecting plate 5 is connect by nut with 4 push rod of cylinder, and one end of spring connecting rod 7 passes through
Screw is mounted on connecting plate 5, after the other end passes through the through-hole of sealing installation panel 6, puts on compressed spring 8, then twist at the end
Upper band grommet screw makes compressed spring be between band grommet screw and sealing installation panel 6, and polyethylene strip 2 is mounted on by screw
On connecting plate 5, rubber weather strip 3 is mounted in the slot of polyethylene strip 2.
In the present embodiment, when machine is run and closes overhead door, cigarette making and tipping machine is supplied to cylinder 4, and then passes through gas
The push rod of cylinder 4 pushes connecting plate 5 to be moved to another overhead door end face, on the one hand the movement of connecting plate 5 pushes polyethylene strip 2, from
And rubber weather strip 3 is pushed to press to another overhead door end face, it realizes sealing, spring connecting rod 7 is on the other hand driven to move, this
When, the compressed spring being sleeved in spring connecting rod 7 is since the effect of sealing installation panel 6 is in compressive state；Work as machine down
And overhead door need rise when, cylinder 4 is died, and then compressed spring 8 is in the state procedure that affranchises, pullback spring connecting rod
7 and connecting plate 5, cylinder 4 is made to bounce back, while polyethylene strip 2 and rubber weather strip 3 bounce back, rubber weather strip 3 is made to completely disengage separately
One overhead door end face, then rise overhead door.
Number of cylinders is 3 in the present embodiment.
Spring connecting rod quantity is 6.
The pneumatic sealing device, simple in structure, sealing effect is good, and without impact, service life is long for no friction.
