Description

Technical Field

[0001] The invention belongs to the technical field of plate pressing production equipment, in particular to short-wave fiber-reinforced polyurethane plate pressing production equipment. Background Art

[0002] Polyurethane sheet refers to a polyurethane sandwich panel made entirely of PU or a composite of PU and color-coated steel plates. It has become the most widely used product system of PU and is mainly used in external insulation systems of industrial and civil buildings. Polyurethane sheet has the characteristics of low thermal conductivity, good thermal performance, moisture-proof, waterproof, fire-proof, flame-retardant, high temperature resistance, and strong deformation resistance.

[0003] Polyurethane sheets are formed by combining multiple layers of materials. When pressing and forming, it is often necessary to inject polyurethane composite materials between the bottom plate and the upper non-woven fabric. The polyurethane composite materials are liquid. In order to prevent the paint from spraying out of the bottom plate, gaps will be left on the edges of the bottom plate without spraying when the polyurethane composite materials are actually sprayed. This results in unsatisfactory spraying effects and poor insulation effects at the edges of the bottom plate. At the same time, after spraying, the polyurethane composite materials will be immediately covered and squeezed by the roller with the upper non-woven fabric. Affected by the squeezing, the liquid paint flows to the edges of the bottom plate, making it easy for the paint to adhere to the junction of the bottom plate edge and the roller. The traditional way to clean the paint on the roller surface is to stop the press after the press has completed its work and then remove the paint on the surface. This method affects the flatness of the roller surface during processing and leads to poor roller pressing effects.

Since the upper non-woven fabric is constantly moving, the pressing shaft will also move continuously and apply pressure to the upper non-woven fabric, thereby compensating for the roller shaft bending or deformation due to excessive load and uneven wear during operation, resulting in high pressure in the middle of the roller shaft, while the pressure at both ends gradually decreases, so that the bottom plate and the edge of the upper non-woven fabric are not pressed in place, resulting in the situation that the processed and formed plate does not meet the standard. When a batch of materials is processed, the connecting rod also follows the guide plate to reset, and the sleeve is reset under the action of the torsion spring, and then resets with the scraper, and the scraper fits the surface of the roller shaft, and then scrapes off the paint adhered to the surface of the roller shaft, thereby solving the problem that the paint adheres to the surface of the roller shaft and affects its surface flatness, resulting in unsatisfactory lamination effect.

[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0042] like Figures 1 to 12 As shown, the short-wave fiber reinforced polyurethane sheet lamination production equipment described in the embodiment of the present invention comprises a lamination molding machine 1 and a spraying machine 2 fixedly installed on the top, the spraying machine 2 is equipped with a spray gun that can reciprocate, and the lamination molding machine 1 is fixedly equipped with two symmetrically arranged fixed tables 3, and the two fixed tables 3 are rotatably connected to the sides close to each other with rollers 4, and a bottom plate 5 is placed on the lamination molding machine 1, and the surface of the roller 4 is abutted against an upper non-woven fabric 6;

[0043] A leak-proof mechanism 10 is provided on the pressing and molding machine 1. The leak-proof mechanism 10 includes two fixed frames 11 fixedly installed on the pressing and molding machine 1. An electric push rod 12 is fixedly installed inside the fixed frame 11. A guide plate 13 is fixedly connected to the output end of the electric push rod 12. A guide groove 14 is provided on the inclined surface of the guide plate 13. A storage box 16 is fixedly installed on one side of the pressing and molding machine 1. The storage box 16 and the guide groove 14 are connected by a guide pipe 15. A telescopic support block 17 is fixedly installed between the guide plate 13 and the inner wall of the fixed frame 11. The telescopic support block 17 is composed of a plurality of hollow blocks that slide.

[0044] During operation, when the pressing and forming machine 1 is started, the bottom plate 5 has been laid on the pressing and forming machine 1, and a part of the upper non-woven fabric 6 has passed through the roller 4, so that the upper non-woven fabric 6 can be driven to move when the roller 4 rotates. At this time, the electric push rod 12 in the fixed frame 11 is started, and the electric push rod 12 is allowed to move the guide plate 13 toward the bottom plate 5, so that the two guide plates 13 and the edges of the bottom plate 5 fit together, and the telescopic support block 17 provides support and auxiliary movement for the guide plate 13. Then start the sprayer, and let the paint be sprayed back and forth evenly on the bottom plate 5 through the spray gun of the sprayer. At the same time, there is no need to leave a margin on the edge of the bottom plate 5 during spraying, so that the sprayed paint can completely cover the bottom plate 5, achieving a better and more uniform bonding effect, and also allowing the upper non-woven fabric 6 and the bottom plate 5 to have a better insulation effect after being pressed together. At the same time, the excess and splashed paint during spraying will be guided into the guide groove 14 by the inclined surface of the guide plate 13, and then introduced into the storage box 16 through the guide groove 14 and the guide pipe 15 for storage, so as to facilitate the next use. The closed guide and storage design can minimize the pollution of the paint and slow down the drying of the paint, so as to better utilize the paint.

[0045] Specifically, the guide plate 13 is internally installed with a stirring assembly 18 for accelerating the flow of the paint in the guide groove 14. The stirring assembly 18 includes a receiving groove 181 opened in the guide plate 13 and connected to the guide groove 14. A servo motor 182 is fixedly installed in the receiving groove 181. A screw rod 183 is installed at the output end of the servo motor 182. A sleeve plate 184 is movably connected to the surface of the screw rod 183. A plurality of conical stirring rods 184 are fixedly installed on one side of the sleeve plate 184. 85, a plurality of sleeve rings 186 are rotatably connected to the surface of the stirring rod 185, a plurality of conical rods are fixedly connected to the surface of the sleeve ring 186, an arc-shaped cleaning plate is fixedly installed on the end of the stirring rod 185 away from the sleeve plate 184, and the end of the cleaning plate away from the stirring rod 185 is in contact with the inner wall of the guide groove 14, and a stretchable bellows 187 passing through the sleeve plate 184 is fixedly installed inside the receiving groove 181, and both sides of the bellows 187 are slidably connected to the inner wall of the guide plate 13.

[0046] During operation, when the paint passes through the guide groove 14, the servo motor 182 in the receiving groove 181 is started, and the servo motor 182 drives the sleeve 184 on the screw 183 to reciprocate, and the sleeve 184 drives the stirring rod 185 to stir the paint in the guide groove 14, thereby accelerating the flow of the paint, and the cleaning plate at one end of the stirring rod 185 scrapes the inner wall of the guide groove 14 to reduce the paint adhesion to the inner wall of the guide groove 14, causing the flow to decrease or block. When the paint flow is too much, it will drive the sleeve 186 to rotate when flowing through the stirring rod 185, so that the rotating sleeve 186 and the conical rod on its surface accelerate the flow of the paint, and the bellows 187 can effectively prevent the paint from entering the receiving groove 181 and affecting the operation of the screw 183 and the servo motor 182, which plays a good protective role.

[0047] Specifically, a heating component 19 is provided in the storage box 16 to prevent the paint from solidifying. The heating component 19 includes a partition 192 installed in the storage box 16 for dividing it into an upper chamber and a lower chamber. A heating wire 191 is electrically connected to the lower chamber of the storage box 16. A connecting pipe 193 connected to the lower chamber is installed on the side of the storage box 16 away from the fixed frame 11. The connecting pipe 193 is made of flexible material and is wrapped around the surface of the guide pipe 15. A plurality of through holes 194 are provided on the top of the partition 192, and a waterproof and breathable cloth 195 and a bracket 196 with an arc-shaped top are fixedly installed inside the through hole 194. The bracket 196 lifts up the waterproof and breathable cloth 195.

[0048] During operation, in order to prevent the paint in the storage box 16 from solidifying after cooling, a heating wire 191 is installed, and the heat emitted by the heating wire 191 flows into the upper chamber of the storage box 16 through the through hole 194, heating the paint stored in the upper chamber, thereby effectively preventing the stored paint from solidifying. At the same time, the heat generated by the heating wire 191 can also be transmitted through the connecting pipe 193. Since the connecting pipe 193 is wound around the guide pipe 15, the hot air is used to heat the paint in the guide pipe 15, effectively preventing the paint from cooling on the way and causing the flow rate to slow down.

[0049] A pressing assembly 20 is provided on one side of the fixed platform 3, and the pressing assembly 20 includes a rectangular groove 21 which is penetrated and opened on the fixed platform 3, and an inverted "V"-shaped pressure plate 23 is slidably connected to the inside of the rectangular groove 21 through a spring, and a connecting rod 22 is fixedly installed on one side of the guide plate 13, and an inclined plate is installed at one end of the connecting rod 22 away from the guide plate 13 and fits with the pressure plate 23, and a fixed column 24 is fixedly installed on one side of the fixed platform 3 close to the roller shaft 4, and a sleeve 25 is rotatably sleeved on the surface of the fixed column 24 through a torsion spring, and an inclined fixed block 26 and a fixed rod 28 are fixedly installed on the surface of the sleeve 25, one end of the fixed block 26 is rotatably connected to a pressure roller 27, and a scraper 29 is fixedly installed at one end of the fixed rod 28 away from the sleeve 25.

[0050] Specifically, a plurality of rollers 30 are rotatably connected to the surface where the pressure plate 23 and the connecting rod 22 are in contact, a groove which is inclined downward and for the pressure plate 23 to slide is provided inside the fixed platform 3, a plurality of hollow blocks in the telescopic support block 17 are sealed and slidably connected, and a hose 31 connected to the interior is fixedly installed at one end of the telescopic support block 17 away from the guide plate 13, and one end of the hose 31 away from the telescopic support block 17 is close to the bottom of the scraper 29, and an air duct 32 connected to the interior is connected to one side of the storage box 16, and one end of the air duct 32 away from the storage box 16 is aligned with the roller 4.

[0051] During operation, when the guide plate 13 moves, it will drive the connecting rod 22 to move together. Since one end of the connecting rod 22 is in contact with the pressure plate 23, the connecting rod 22 will push the pressure plate 23 to move. By installing a plurality of rollers 30 on the pressure plate 23, friction can be reduced to facilitate the connecting rod 22 to efficiently push the pressure plate 23. At the same time, the inclined groove provides a designated path for the sliding of the pressure plate 23, so that it can only slide obliquely downward. The sliding pressure plate 23 squeezes the fixed block 26 on the sleeve 25, allowing the fixed block 26 to carry the pressure roller 27 rotates downward, allowing the pressing roller 27 to press on the surface of the upper non-woven fabric 6. Since the upper non-woven fabric 6 is constantly moving, the pressing roller will also continuously move and apply pressure to the upper non-woven fabric 6, thereby compensating for the bending or deformation of the roller 4 due to excessive load and uneven wear during operation, resulting in high pressure in the middle of the roller, while the pressure at both ends gradually decreases, making the bottom plate 5 and the edge of the upper non-woven fabric 6 not pressed in place, resulting in the processed and formed plate not meeting the standards. When a batch of materials is processed, there will be residual paint adhered to the edge of the roller 4 and the bottom plate 5. The electric push rod 12 is started again, and the electric push rod 12 is allowed to shrink and reset with the guide plate 13 into the fixed frame 11, and the connecting rod 22 is also reset with the guide plate 13, so that the pressure plate 23 and the fixed block 26 on the sleeve 25 are no longer squeezed. The sleeve 25 is reset under the action of the torsion spring, and then resets with the scraper 29. The scraper 29 fits with the surface of the roller 4, and then scrapes off the paint adhered to the surface of the roller 4, thereby solving the problem of the paint adhering to the surface of the roller 4 affecting its surface flatness, resulting in an unsatisfactory pressing effect. Since the hot air from the heating wire 191 flows to the adhesive part of the roller 4 through the air guide tube 32, the adhered paint will not adhere too tightly, so that the scraper 29 can easily scrape off the paint. At the same time, during the next extension and retraction process of the electric push rod 12, the gas in the telescopic support block 17 will be squeezed, so that the gas in the telescopic support block 17 will be blown to the scraper 29 through the hose 31, thereby cleaning the scraper 29 and effectively avoiding residual paint at the port of the scraper 29. At the same time, the guide plate 13 slides and retracts into the fixed frame 11 to facilitate the placement of the next batch of bottom plates 5 on the pressing and forming machine 1 for processing.

[0052] A grinding assembly 40 is provided on one side of the fixed frame 11, and the grinding assembly 40 includes a connecting plate 41 fixedly installed on one side of the fixed frame 11. An adjustable grinding plate 42 is screwed to one side of the connecting plate 41 close to the bottom plate 5, and sandpaper is installed on one side of the grinding plate 42 close to the bottom plate 5.

[0053] During operation, since the paint is between the bottom plate 5 and the upper non-woven fabric 6, and the paint will overflow from the edge during pressing, sandpaper is installed on the grinding plate 42 to grind the overflowed paint, effectively avoiding the situation that the overflowed paint is difficult to remove after it is completely solidified. At the same time, according to the different thicknesses of the bottom plate 5 and the upper non-woven fabric 6, the grinding plate 42 is adjusted by adjusting the screw to adapt to the bottom plate 5.

[0054] Working principle: When the pressing and forming machine 1 is started, the bottom plate 5 has been laid on the pressing and forming machine 1, and a part of the upper non-woven fabric 6 has passed through the roller 4. The electric push rod 12 in the fixed frame 11 is started, and the electric push rod 12 is allowed to move with the guide plate 13 toward the bottom plate 5. The two guide plates 13 and the edges of the bottom plate 5 are fitted together, and the telescopic support block 17 provides support and auxiliary movement for the guide plate 13. Then the sprayer is started, and the paint is sprayed back and forth evenly on the bottom plate 5 through the spray gun of the sprayer. At this time, the excess and splashed paint during spraying will be guided into the guide groove 14 by the inclined surface of the guide plate 13. When the paint passes through the guide groove 14, the servo motor 182 in the storage groove 181 is started, and the servo motor 182 drives the sleeve plate 184 on the screw rod 183 to reciprocate, and the sleeve plate 184 stirs the paint in the guide groove 14 with the stirring rod 185. When the paint flow is too much, the paint will be driven to rotate the ring 186 when flowing through the stirring rod 185, so that the rotating ring 186 and the conical rod on its surface accelerate the flow of the paint, and then the paint is introduced into the storage box 16 through the guide groove 14 and the guide pipe 15 for storage.

[0055] By installing the heating wire 191, the heat emitted by the heating wire 191 flows into the upper chamber of the storage box 16 through the through hole 194, thereby heating the paint stored in the upper chamber. At the same time, the heat generated by the heating wire 191 can also be transmitted through the connecting tube 193. Since the connecting tube 193 is wound around the guide tube 15, the hot air is used to heat the paint in the guide tube 15.

[0056] When the guide plate 13 moves, it will drive the connecting rod 22 to move together. Since one end of the connecting rod 22 is in contact with the pressure plate 23, the connecting rod 22 will push the pressure plate 23 to move. By installing a plurality of rollers 30 on the pressure plate 23, the friction can be reduced to facilitate the connecting rod 22 to efficiently push the pressure plate 23. At the same time, the inclined groove provides a designated path for the sliding of the pressure plate 23, so that it can only slide diagonally downward. The sliding pressure plate 23 squeezes the fixed block 26 on the sleeve 25, allowing the fixed block 26 to rotate downward with the pressure roller 27, so that the pressure roller 27 is pressed on the surface of the upper non-woven fabric 6. Since the upper non-woven fabric 6 is constantly moving, the pressure shaft will also move continuously and exert pressure on the upper non-woven fabric 6. When a batch of materials is processed, the electric push rod 12 is started again, and the electric push rod 12 and the guide plate 13 are retracted and reset into the fixed frame 11, and the connecting rod 22 is also reset with the guide plate 13, so that the pressing plate 23 and the fixed block 26 on the sleeve 25 are no longer squeezed, and the sleeve 25 is reset under the action of the torsion spring, and then the scraper 29 is reset, and the scraper 29 is fitted with the surface of the roller 4 to perform the scraping operation. The hot air of the heating wire 191 flows to the adhesive part of the roller 4 through the air guide pipe 32, which facilitates the scraper 29 to easily scrape off the paint. At the same time, during the next extension and retraction process of the electric push rod 12, the gas in the telescopic support block 17 will be squeezed, so that the gas in the telescopic support block 17 is blown to the scraper 29 through the hose 31, thereby cleaning the scraper 29.

[0057] The overflowed paint is polished by installing sandpaper on the polishing plate 42. At the same time, according to the different thicknesses of the bottom plate 5 and the upper non-woven fabric 6, the polishing plate 42 is adjusted by adjusting the screws to adapt to the bottom plate 5.
