Description

Technical Field

[0001] The invention belongs to the technical field of laminating devices, and in particular relates to a surface film pasting device for a foam plastic sound insulation board. Background Art

[0002] Foam plastic sound insulation board is a building material with excellent performance. It can effectively prevent the transfer of heat, significantly reduce the loss of indoor heat, reduce heating energy consumption, and absorb and block the spread of sound, providing a quiet environment for the room. In order to improve the protective performance of foam plastic sound insulation board, it is usually necessary to stick a layer of protective film on the foam plastic sound insulation board after it is produced. The protective film made of biomass conversion material has the properties of sustainability, low carbon emission, biodegradability, and reduced dependence on oil, so it is widely used on insulation board. Due to the chemical properties of biomass materials, The chemical properties may lead to insufficient adhesion to the surface of the insulation board, which is prone to falling off or warping. Therefore, before the protective film made of biomass conversion material is affixed to the insulation board, it needs to be coated with glue. For example, a polystyrene foam sound insulation board surface film pasting device proposed in the authorization publication number CN208428782U allows the protective film and the EPS insulation board to fit seamlessly. On the one hand, it avoids the entry of air and loss of viscosity. On the other hand, it allows the EPS insulation board to fit seamlessly with the object of use during use, is not easy to fall off, and greatly extends the service life.

[0003] The existing film pasting device still has the following problems when pasting the film on the foam plastic sound insulation board:

[0004] When the protective film is applied to the surface of the foam plastic sound insulation board, the factory usually controls the film application device to run at a specific speed to ensure its working efficiency. However, when the film application device works at a faster speed, the gas between the protective film and the foam plastic sound insulation board will not be discharged in time, and small bubbles will be generated on the surface of the foam plastic sound insulation board. These bubbles will form gaps between the protective film and the foam plastic sound insulation board, causing the paths of heat conduction and sound propagation to change, thereby reducing the insulation and sound insulation effects, and also affecting the flatness and overall appearance of the foam plastic sound insulation board. At this time, the operator is required to use a sharp needle to poke a very small hole on the surface of the bubble to release the gas, and compact the bubble with the help of a pressure roller, which undoubtedly increases the workload of the operator, but if the working speed of the film application device is greatly reduced, its working efficiency will be seriously affected.

[0005] Therefore, a foam plastic sound insulation board surface film pasting device is proposed to solve the above problems. Summary of the invention

The metal block 25 is electrically connected to the electromagnetic block 17 and the induction component 31 through the PLC controller 58. When bubbles are generated between the insulation board and the protective film 6 due to the fast fitting speed, the bubbles can be automatically burst, and then the raised parts of the bubbles are pressed to restore the surface of the insulation board to a flat state, thereby ensuring the thermal insulation and sound insulation performance of the insulation board, and no manual cleaning is required, thereby reducing the workload of the operator.

[0034] The induction assembly 31 includes an induction box 311 and an induction tube 312. The induction box 311 is fixedly connected to the front side wall of the base 1. The induction box 311 is connected to the air outlet pipe 30 through the induction tube 312. A control valve 32 is arranged in the induction tube 312. An air pressure hole is opened on the left side wall of the induction box 311. The left inner wall of the induction box 311 is fixedly connected to a piston plate 33 through a spring. The lower inner wall of the induction box 311 is fixedly connected to a stopper 34. The lower side wall of the induction box 311 is inlaid with a microporous plate 35 located on the right side of the stopper 24. The left side wall of the piston plate 33 is fixedly connected to a horizontal box 36. The right side wall of the horizontal box 36 is connected to a horizontal tube 37. The right end of the horizontal tube 37 extends out of the piston plate 33. The lower side wall of the horizontal box 36 is fixedly connected to an elastic air bag 38. The lower side wall of the elastic air bag 38 is fixedly connected to a convex seat 39. A plurality of trigger switches 40 are embedded on the lower inner wall of the box 311, and the pressing part of the trigger switch 40 is connected to the arc block 41.

A buzzer 44 is fixedly connected to the front side wall of the base 1. The squeezing switch 43 is electrically connected to the buzzer 44 through the PLC controller 58, and can sense the amount of bubbles on the surface of the insulation board. When it is sensed that there are many bubbles on the surface of the insulation board, the working speed of the film laminating device can be automatically slowed down to avoid bubbles generated when the bubbles between the protective film 6 and the insulation board are not discharged in time due to the film laminating device working too fast, thereby ensuring the working performance of the film laminating device.

[0035] The tensioning assembly 45 includes an electric push rod 451 and a working cylinder 452. The electric push rod 451 is fixedly connected to the upper side wall of the rear connecting plate 4. The working cylinder 452 is fixedly connected to the output end of the electric push rod 451. A lifting plate 46 is slidably arranged in the working cylinder 452. The same spring is fixedly connected between the lifting plate 46 and the working cylinder 452. An electric contact frame 47 is fixedly connected to the upper side wall of the lifting plate 46. The electric contact frame 47 is electrically connected to an external power supply. Two electric contact blocks 48 are embedded in the right inner wall of the working cylinder 452.

A lifting rod 49 is fixedly connected to the upper side wall of the lifting plate 46. The upper end of the lifting rod 49 extends out of the working cylinder 452 and is connected to Tensioning roller 50. When the tension of the protective film 6 is relatively small, the tensioning roller 50 will drive the electric contact frame 47 to move upward and release the upper electric contact block 48 under the elastic force of the spring. The upper electric contact block 48 is electrically connected to the positive circuit of the electric push rod 451, and the electric contact frame 47 is electrically connected to the external power supply, so that the electric push rod 451 can be controlled to drive the working cylinder 452 and the tensioning roller 50 to move upward, thereby increasing the tensioning force of the protective film 6. On the contrary, when the tension of the protective film 6 is too large, the electric push rod 451 will drive the tensioning roller 50 to move downward. This structure can keep the protective film 6 under appropriate tension conditions when it is attached to the surface of the insulation board for film pasting, thereby avoiding the problem of wrinkles on the protective film 6 during the glue coating and pressing stage due to too small tension, thereby ensuring the film pasting quality of the insulation board.

[0036] The glue spraying assembly 51 includes a fixed seat 511 and a glue sol machine 512. The fixed seat 511 is fixedly connected to the rear side wall of the base 1. The glue sol machine 512 is fixedly connected to the upper side wall of the fixed seat 511. The side wall of the base 1 is fixedly connected to a glue spraying cylinder 52 through a bracket. The lower side wall of the glue spraying cylinder 52 is fixedly connected to multiple glue spraying heads 53. The glue sol machine 512 delivers glue to the glue spraying cylinder 52 through a delivery pump, and can spray the glue evenly onto the protective film 6.

[0037] The lower side wall of the cross box 36 is fixedly connected with a connecting tube 54, a connecting block 55 is inserted in the connecting tube 54, and the lower side wall of the connecting block 55 is fixedly connected with a bent rod 56. The same spring is fixedly connected between the connecting seat 28 and the lower inner wall of the connecting tube 54. The lower end of the bent rod 56 passes through the connecting tube 54 and is fixedly connected to the side wall of the convex seat 39. When the gas in the elastic airbag 38 is discharged, the convex seat 39 will return to its initial position.

[0038] A plurality of contact wheels 57 are fixedly connected to the left and right sides of the lower end of the square cylinder 11. The plurality of contact wheels 57 on both sides are tilted outwardly, so that when the lower end of the square cylinder 11 passes through the bubble, the square cylinder 11 can be moved upward quickly.

[0039] The operating principle of the present invention is now described as follows: when the film pasting device is working, the insulation board is conveyed to the right through the conveying roller structure 2. When the insulation board moves to the bottom of the second guide roller 8, the protective film 6 guided by the second guide roller 8 will be located above the insulation board. When the protective film 6 passes under the glue spraying tube 52, the glue will be sprayed evenly to the protective film 6 through the glue spraying head 53. When the protective film 6 and the insulation board pass under the pressing roller structure 9 (the transmission modes of the conveying roller structure 2 and the pressing roller structure 9 are both existing mature technologies and will not be described in detail in this article), the protective film 6 and the insulation board are pressed together by the pressing roller structure 9. When the conveying speed of the conveying roller structure 2 and the pressing roller structure 9 is too fast, a small amount of gas between the protective film 6 and the insulation board will not be discharged in time. After the protective film 6 and the insulation board are pressed together, the gas will form bubbles between the protective film 6 and the insulation board.

[0040] When the bubble passes directly under the detection and cleaning component 10, the contact wheel 57 at the lower end of the bubble will contact the bubble. The bubble is a convex structure, and the middle point of the bubble is at the highest position. When the bubble moves to the right, the bubble will gradually push the square tube 11 upwards. The square tube 11 will drive the wheel frame 19 and the metal wheel 20 to move upwards through the fixing plate 18 and the bracket. The metal wheel 20 fits the inner wall of the vertical tube 102. When the metal wheel 20 moves upward, the metal wheel 20 rotates clockwise along the inner wall of the vertical tube 102. During the rotation, the metal wheel 20 will bring The movable metal stopper 22 rotates together with the insulating layer 21. When the metal stopper 22 rotates upward, it will contact the upper stopper 24, so that the metal wheel 20 stops rotating. At this time, the insulating layer 21 will rotate and contact the vertical cylinder 102. When the square cylinder 11 leaves the highest point in the center of the bubble, the square cylinder 11 will move downward under the action of gravity. In the process of moving downward, the square cylinder 11 will drive the metal wheel 20 to rotate counterclockwise. Referring to the above principle, when the metal wheel 20 moves downward, the metal part of the metal wheel 20 will contact the inner wall of the square cylinder 11. When the square tube 11 drops to a distance of one centimeter from the insulation board, the square tube 11 will drive the metal wheel 20 to contact the metal block 25. At this time, the arc seat 23 is electrically connected to the external power supply, and the external current is transmitted to the metal wheel 20 through the metal stop rod 22. When the metal wheel 20 and the metal block 25 are in contact, the external current is transmitted to the metal block 25, and the metal block 25 is electrically connected to the PLC controller 58. The metal block 25 transmits an electrical signal to the PLC controller 58. After receiving the electrical signal, the PLC controller 58 The electromagnetic block 17 will be controlled to contact the external power supply for one second. After being powered on, the electromagnetic block 17 will generate magnetic attraction, thereby attracting the permanent magnetic plate 15 to move downward. The permanent magnetic plate 15 drives the needle 12 to move downward through the curved plate 14 and the horizontal plate 13, so that the needle 12 extends out of the square tube 11, and the needle 12 is used to pierce a very small hole on the surface of the bubble. Under the subsequent lamination of the lamination roller structure 9, the gas in the bubble will be discharged through the puncture point, thereby ensuring the thermal insulation and sound insulation performance of the insulation board, and no manual cleaning is required, reducing the workload of the operator;

[0041] At the same time, the PLC controller 58 will also energize the control valve 32 for one second. When the insulation board is filmed, the air pump 29 is always in the open state. The air pump 29 delivers the high-pressure gas to the dust cleaning box 26 through the air outlet pipe 30 and discharges it through the dust cleaning head 27 to further clean the dust remaining on the surface of the insulation board. When the control valve 32 is energized and opened for one second, the gas delivered by the air pump 29 will be delivered to the induction box 311 through the induction tube 312, so that the air pressure in the space on the right side of the piston plate 33 increases. Under the action of the air pressure, the piston plate 33 will drive the horizontal box 36 and the convex box 36 to move. The convex seat 39 moves to the left together, and before the piston plate 33 moves, the external gas will be first transported to the elastic airbag 38 through the cross pipe 37 and the cross box 36, so that the elastic airbag 38 is inflated, and the elastic airbag 38 will drive the convex seat 39 to move downward, so that the convex seat 39 contacts the lower inner wall of the sensing box 311. When the control valve 32 is opened for one second, the piston plate 33 will only move a short position to the left. After the control valve 32 is opened ten times, the piston plate 33 will drive the convex seat 39 to contact the trigger switch 40 on the far right, and the convex seat 39 will squeeze the rightmost side. The arc block 41 above the trigger switch 40, through the cooperation between the convex seat 39 and the arc block 41, the arc block 41 will move downward, thereby squeezing the trigger switch 40, and the trigger switch 40 will send an electrical signal to the PLC controller 58. After receiving the electrical signal, the PLC controller 58 will control the conveying power of the conveying roller structure 2 and the pressing roller structure 9 to reduce, thereby reducing the film-laminating speed of the insulation board, avoiding the bubbles generated because the film-laminating device works too fast and the bubbles between the protective film 6 and the insulation board cannot be discharged in time. When the convex seat 39 squeezes the two trigger switches 40 on the left, the film-sticking speed of the insulation board will be further reduced. When the bubbles are not caused by the excessive film-sticking speed, the horizontal box 36 will continue to move to the left to press the squeezing switch 43. The squeezing switch 43 will control the buzzer 44 through the PLC controller 58 to remind the operator to find other reasons for the bubbles in the film-sticking of the insulation board. The gas inside the induction box 311 can be slowly discharged through the microporous plate 35, thereby allowing the insulation board to have a small amount of bubbles within a reasonable range when the film-sticking speed is faster.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
