Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and 2, the present invention provides a production system of a vacuum insulation mineral wool board, comprising a conveying device, and an inclined roller conveying device, a getter bonding device, a film laminating device and a vacuum packaging device which are sequentially arranged on the conveying device according to a core material conveying direction, wherein the inclined roller conveying device is used for aligning the core material, the getter bonding device is used for bonding a getter on the core material, the film laminating device is used for laminating a high gas barrier film with a size larger than that of the core material on the upper surface of the core material, and the vacuum packaging device is used for vacuum packaging the high gas barrier film on the outer edge of the lower surface of the core material.
The vacuum packaging device comprises a sealed isolation chamber 1 which forms a sealed isolation space after a flip cover is closed, a core material aligning mechanism 2 used for aligning the position of a core material is installed inside the sealed isolation chamber 1, a film vacuum laminating mechanism 3 used for laminating a high-gas-barrier film on the outer side of the core material is installed inside the sealed isolation chamber 1, a vacuum generating device 4 matched with the sealed isolation space inside the sealed isolation chamber 1 to form a vacuum environment is installed at the bottom end of the sealed isolation chamber 1, and a film sealing device 5 used for packaging the redundant high-gas-barrier film on the core material is installed on the film vacuum laminating mechanism 3.
When the core material bonded with the getter and laminated high-gas-resistance film is transported to a vacuum packaging device along with a conveying device, the core material is placed on a core material limiting supporting plate 11 of a sealed isolation chamber 1, then a core material aligning mechanism 2 is started, and the core material is pushed out synchronously through push plates in four directions and is pushed on the core material limiting supporting plate 11.
If the push plate extrudes redundant high gas-barrier film, the pressure on the high gas-barrier film can be reduced by limiting the push plate pushing-out force of the core material aligning mechanism 2, and the high gas-barrier film material has certain toughness, so that the high gas-barrier film is not easy to damage when being extruded by the push plate with smaller extrusion force.
On the other hand, because the high gas barrier film is of a single-layer structure, and in the process of preliminary lamination through the film vacuum laminating mechanism 3, air between the high gas barrier film and the upper surface of the core material is exhausted, when the core material is placed in the sealed isolation chamber 1 and is in a vacuum state, the shape of the high gas barrier film per se cannot be greatly changed, the probability of extruding the high gas barrier film is reduced by adjusting the contact height between the push plate of the core material aligning mechanism 2 and the periphery of the core material, and when the peripheral side surface of the core material and the longitudinal central axis of the push plate of the core material aligning mechanism 2 are in a lower position, the redundant part of the high gas barrier film is difficult to naturally fall below the longitudinal central axis under the action of the toughness of the material of the core material, so that the core material aligning mechanism 2 is difficult to extrude redundant high gas barrier film when the periphery of the core material is extruded.

The folding pressure bar mechanism 32 comprises a second push rod 321 fixedly installed on the sliding block 312, an output end of the second push rod 321 faces downwards and is rotatably connected with a torsion energy storage connecting rod 322 which inclines outwards and is connected with the edge sealing installation roller frame 331, a connection position of the torsion energy storage connecting rod 322 and the second push rod 321 is sleeved with a second torsion spring 323 to keep the inclination state of the torsion energy storage connecting rod 322, the torsion energy storage connecting rod 322 is elastically abutted to the upper surface of the core material to drive the torsion energy storage connecting rod 322 to enlarge the outwards inclined angle after the torsion energy storage connecting rod 322 is matched with the turning cover of the sealed isolation chamber 1 to be closed, and the output end of the second push rod 321 is controlled to retract through a sensor 335.
In the process of closing the sealed isolation room 1, the two groups of folding pressure bar mechanisms 32 mounted on the power rail device 31 contact the upper surface of the core material first, and are continuously closed along with the turning cover of the sealed isolation room 1, under the condition that the length of the second push rod 321 is unchanged, the two groups of torsion energy storage connecting rods 322 for extruding the upper surface of the core material rotate along the joint of the second push rod 321 to increase the inclination of the torsion energy storage connecting rods, and simultaneously the second torsion spring 323 is twisted, at the moment, the film pressure rollers 333 mounted inside the edge sealing mounting roller frame 331 at the bottom end of the torsion energy storage connecting rods 322 roll outwards for a small distance under the action of the increase of the inclination of the torsion energy storage connecting rods 322, and the high gas barrier film on the upper surface of the core material is leveled in the rotating process.
When the turnover cover of the sealed isolation chamber 1 is completely closed, the bending degree of the torsion energy storage connecting rod 322 does not change, and the second torsion spring 323 releases elasticity to drive the torsion energy storage connecting rod 322 to obliquely press on the upper surface of the core material, at this time, the second motor 314 controlling the power guide rail device 31 starts to drive the two-way threaded screw rod 313 to start rotating, the two sliding blocks 312 are driven to slide towards two sides along the guide rails 311 under the action of the rotation of the two-way threaded screw rod 313, the two sliders 312 drive the folding pressure bar mechanisms 32 arranged on the sliders to move towards two sides, at the moment, the two groups of folding pressure bar mechanisms 32 and the compression roller switch mechanisms 33 extruding the upper surface of the core material move towards the outer side, in the process, the film pressing roller 333 which is rotatably connected to the edge sealing mounting roller frame 331 and the film pressing roller 333 which is rotatably connected to the opening and closing roller frame 332 roll along the upper surface of the core material in the moving process, so that air bubbles and wrinkles which may exist on the upper surface of the core material are flattened.
When the two groups of folding pressure bar mechanisms 32 move to the outer edges of the two sides of the core material, the film pressing rollers 333 which are rotatably connected to the edge banding mounting roller frame 331 roll from the upper surface of the core material to the side surfaces of the core material, and at the moment, the second torsion spring 323 releases elasticity, so that the film pressing rollers 333 on the edge banding mounting roller frame 331 press redundant protrusions of the high-gas-barrier film to the two side surfaces of the core material.
Meanwhile, the switch roller frame 332 rotatably connected to the edge sealing mounting roller frame 331 is jacked up along the side edge of the core material in the process that the edge sealing mounting roller frame 331 descends, when the film pressing roller 333 on the edge sealing mounting roller frame 331 presses the side edge of the core material, the switch roller frame 332 rotates until the switch roller frame is detected by the sensor 335 mounted on the torque energy storage connecting rod 322, the sensor 335 provides a switching signal to the PLC controller, the preset program processing is performed, the third motor 52 mounted in the switch roller frame 332 is controlled to start, the third motor 52 drives the turning frame 51 to turn downwards through a belt until the film sealing device 5 mounted on the turning frame 51 is attached to the area, close to the outer edge, of the lower surface of the core material, the packaging thermal resistance device 53 on the film sealing device 5 is started to package the high-gas-resistance film at the outer edge of the lower surface of the core material, and the remaining part is fused through the thermal resistance fusing device 54, the appearance of the mineral wool board processed by the core material is guaranteed.
Because the film sealing device 5 arranged on the roll-over stand 51 rotates along the film pressing roller 333 arranged on the edge sealing mounting roller stand 331 in the process of turning over downwards, the film sealing device 5 is not easy to wrinkle when turning over downwards and laminating redundant parts of the high-gas-resistance film, and the high-gas-resistance film is packaged in a vacuum environment without bubbling, so that the effect of packaging the high-gas-resistance film on two sides of the core material is better.
After the film sealing device 5 packages the high-gas-resistance films protruding from the two ends of the core material, the PLC controls the third motor 52 to rotate reversely, so that the roll-over stand 51 is driven to be lifted to the original height again, the second push rods 321 of the two groups of folding pressure bar mechanisms 32 are controlled to retract, the core material is not extruded by the compression roller switch mechanism 33, the second motor 314 is controlled to drive the two-way threaded screw rod 313 to rotate reversely, the two groups of sliding blocks 312 are driven to move relatively to the original position, and the high-gas-resistance film packaging steps on the left side and the right side of the core material are completed.

Specifically, the first push rods 132 at the front end and the rear end of the core material limiting supporting plate 11 are controlled to retract firstly, so that the two core material side clamping rods 13 do not extrude the front end side face and the rear end side face of the core material any more, and then the first motor is controlled to drive the core material limiting supporting plate to rotate by 90 degrees, so that the left side face and the right side face of the core material which is originally packaged are changed into a front side face and a rear side face, the first push rods 132 at the front end face and the rear end face of the core material limiting supporting plate 11 are controlled to extend out according to the steps, the two core material side clamping rods 13 are driven to cooperate with the front end side face and the rear end side face for clamping the core material to be packaged, and the subsequent film vacuum laminating mechanism 3 is convenient to perform secondary packaging on the left side and the right side of the core material according to the steps.
After the secondary packaging is finished, the protruding parts of the high-gas-resistance film on the upper surface of the core material are packaged around the core material, the sealing performance of the high-gas-resistance film, the upper surface of the core material and the periphery of the core material is guaranteed through the packaging heat resistance device 53 of the film sealing device 5, and a small amount of air generated by the core material can be absorbed through the getter adhered to the edge of the upper surface of the core material in the subsequent use process, so that the mineral wool board processed by the core material is wrapped by the high-gas-resistance film to form a stable vacuum environment.
