Description

Technical Field

[0001] This invention belongs to the field of insulation board manufacturing technology, specifically a multi-layer insulation board pressing and molding equipment. Background Technology

[0002] As the name suggests, insulation board is a type of board used for insulation. In order to balance insulation and board strength, insulation board needs to use multiple layers of boards, which are pressed together into a whole to achieve both insulation and strength. Pressing and molding equipment is used in the pressing process.

[0003] In the existing process of pressing insulation boards, the multi-layer board material needs to be cut first. During this process, the board material is transported to the cutting equipment, where it is cut into regular sizes. The cut board material is then deburred to keep its surface clean. Next, the board material is fed to the pressing equipment for pressing. During this process, the workers need to place the boards according to their layers. Glue needs to be applied to the outer surface of multiple single-layer insulation boards. Then, the glue-coated insulation boards are stacked in sequence in the mold of the pressing equipment. Finally, the pressing equipment presses the multiple single-layer insulation boards into a multi-layer insulation board.

[0004] A Chinese patent with publication number CN116442633B discloses a pressing device and pressing method for processing insulation boards. The device uses the weight of the board itself to press some of the assemblies. Based on the length and width dimensions of the board, some of the assemblies are matched to fit the board. Under the heavy pressure of the board, the assemblies that fit the board move downward relative to the unpressed assemblies, thereby forming a reference groove in all the assemblies.

[0005] Existing insulation board pressing equipment requires manual application of adhesive during use. The adhesive-coated insulation board is then placed on the mold of the pressing equipment for pressing. This process requires manual operation, and the adhesive application process consumes a lot of time. Furthermore, during placement, the staff needs to correct the multi-layer insulation boards to ensure that they are in the correct position for pressing, resulting in low pressing efficiency.

[0006] Therefore, the present invention provides a multi-layer thermal insulation board pressing molding equipment. Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0008] The technical solution adopted by the present invention to solve its technical problem is as follows: The multi-layer thermal insulation board pressing molding equipment of the present invention includes a base, a lower mold installed at the top of the base, a top seat fixedly connected to the top of the base by four support columns, a top oil cylinder installed in the middle of the top seat, a lifting pressure head fixed at the bottom of the output rod of the top oil cylinder, the lifting pressure head being slidably connected to the outside of the four support columns, an upper mold installed at the bottom of the lifting pressure head, and one side of the upper mold communicating with an external air extraction device; It also includes a guide frame disposed on one side of the base, the interior of which can pass through a single layer of sheet material, a conveying assembly disposed inside the guide frame, a pair of glue-brushing rollers disposed at the end of the guide frame, and glue-applying assemblies disposed above and below the glue-brushing rollers; In this process, a single-layer sheet is passed through the guide frame, and the glue application component applies glue to the outside of the single-layer sheet through the guide frame. The sheet is then conveyed to the top of the lower mold by the conveying component inside the guide frame.

[0009] Preferably, the conveying assembly includes multiple transmission rollers rotatably connected at equal intervals on both sides inside the guide frame. Each side of the multiple transmission rollers is fitted with a conveyor belt. The distance between the ends of two conveyor belts away from the lower mold is less than the distance between the ends of the conveyor belts close to the lower mold. A first motor is installed at the top of the guide frame, and the end of the shaft of the first motor is fixedly connected to the top of the transmission rollers. When the conveyor belt moves the single-layer board to the top of the lower mold, the single-layer board automatically falls off between the conveyor belts.

[0010] Preferably, both ends of the glue roller are rotatably connected to lifting blocks, both sides of the guide frame are fixed with fixing blocks, the top and bottom ends of the fixing blocks are fixed with guide rods, the lifting blocks are slidably connected to the outside of the guide rods, the outside of the guide rods is fitted with springs, the other end of the guide rods is fixed with a pressure sensor, and the pressure sensor is fixedly connected to one end of the spring.

[0011] Preferably, guide plates are fixed on the side of the upper and lower sets of lifting blocks away from the guide frame, and the two guide plates are symmetrically distributed about the horizontal center line of the fixed block; When a single-layer board is placed between two glue-brushing rollers, the spacing between the two glue-brushing rollers is adjusted by a guide plate.

[0012] Preferably, each set of lifting blocks is rotatably connected to the side near the connecting shaft with a transmission rod, and both ends of the glue brush roller are fixed with connecting shafts. The transmission rod and the connecting shaft are fitted with belts. In this process, a single-layer board drives a transmission rod to rotate, and the transmission rod drives a connecting shaft via a belt, enabling the gluing assembly to pre-apply glue to the glue roller.

[0013] Preferably, the glue application assembly includes guide tubes disposed above and below the glue brush roller, one end of the guide tubes being connected to an external glue supply device, and multiple glue spray tubes being disposed at equal intervals on the side of the guide tubes near the glue brush roller.

[0014] Preferably, a fixed plate is fixed to the top of the lifting block, a rotating rod is rotatably connected between the fixed plates, the outer side of the fixed plate is fixedly connected to the top of the guide pipe, a J-shaped scraper is fixed to one side of the rotating rod, a second motor is installed on one side of one of the fixed plates, and the output shaft of the second motor is fixedly connected to one end of the rotating rod.

[0015] Preferably, a J-shaped scraper is fixed to one side of the rotating rod, and the second motor can drive the rotating rod to rotate so that the J-shaped scraper is pressed against the surface of the glue roller.

[0016] Preferably, both sides of the guide frame are fixed with moving strips, one side of the base is fixed with two support plates, one side of the support plate is rotatably connected with two sets of first gears, the two sets of first gears are meshed with the moving strips, one end of the shaft of one of the first gears is fixed with a second gear, one side of the lifting head is fixed with two lifting plates, and a rack is provided below one side of the lifting plate.

[0017] Preferably, four cylinders are evenly spaced on the outer side of the lower mold. The cylinders are fixedly connected to the base via connecting rods, and a push plate is fixed to the end of the output shaft of the cylinder.

[0018] The beneficial effects of this invention are as follows: 1. The multi-layer thermal insulation board pressing and molding equipment of the present invention uses a conveyor belt to pull the single-layer board into the interior of the guide frame, and a glue roller to apply glue to the outer surface of the single-layer board, thereby realizing automatic glue application during material feeding and reducing the time consumed by applying glue separately.

[0019] 2. The multi-layer thermal insulation board pressing molding equipment of the present invention uses the lifting pressure head to lower the lifting plate when it descends, which can drive the guide frame to move to one side of the support plate, thereby preventing the guide frame from blocking the upper mold when the upper mold and the lower mold are closed, thus affecting normal use.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 8 As shown in the embodiment of the present invention, a multi-layer thermal insulation board pressing molding equipment includes a base 1, a lower mold 11 installed at the top of the base 1, a top seat 13 fixedly connected to the top of the base 1 by four support columns, a top cylinder 131 installed in the middle of the top seat 13, a lifting pressure head 12 fixed at the bottom of the output rod of the top cylinder 131, the lifting pressure head 12 being slidably connected to the outside of the four support columns, an upper mold 121 installed at the bottom of the lifting pressure head 12, and one side of the upper mold 121 communicating with an external air extraction device. It also includes a guide frame 2 set on one side of the base 1. The interior of the guide frame 2 can pass through the single layer of board 3. The interior of the guide frame 2 is equipped with a conveying component. The end of the guide frame 2 is equipped with a pair of glue brushing rollers 22. Glue application components are set above and below the glue brushing rollers 22. When using the device, the single-layer board 3 needs to be placed at the top of the downward mold 11. In the initial state, the lifting pressure head 12 is pulled to a higher position by the top oil cylinder 131. (Refer to...) Figure 1In this state, the worker places the single-layer board 3 into the opening of the guide frame 2. The conveying component inside the guide frame 2 pulls the single-layer board 3 from the opening into the guide frame 2. During this pulling process, the single-layer board 3 passes between two glue-applying rollers 22. At this time, the glue-applying component outputs glue to the outside of the glue-applying rollers 22. As the single-layer board 3 passes between the glue-applying rollers 22, it causes the glue-applying rollers 22 to roll. The glue adhering to the outside of the glue-applying rollers 22 is applied to the surface of the single-layer board 3 as it rolls. The single-layer board 3 is coated with glue on the outside. Then, the single-layer board 3 is conveyed towards the guide frame 2 and closer to the lower mold 11 by the conveying assembly. When the single-layer board 3 is conveyed directly above the lower mold 11, it falls from the inside of the guide frame 2 and lands on the top of the lower mold 11. After placing the single-layer board 3 repeatedly, multiple layers of insulation boards can be stacked on the top of the lower mold 11. Then, the guide frame 2 moves away from the top of the lower mold 11, and the top hydraulic cylinder 131 is activated to push the lifting pressure head 12. The lifting pressure head 12 pushes the upper mold 121 to close above the lower mold 11. When the lower mold 11 and the upper mold 121 are closed, multiple single-layer boards 3 are placed between the lower mold 11 and the upper mold 121. The pressure of the top hydraulic cylinder 131 presses the multiple single-layer boards 3 together. At the same time, the external air extraction device extracts air from the upper mold 121, keeping the space between the upper mold 121 and the lower mold 11 in a vacuum state. In the vacuum state, the glue air bubbles between the multiple single-layer boards 3 are eliminated, enhancing the bonding effect between the multiple single-layer boards 3, so that the multiple single-layer boards 3 are pressed together to form a multi-layer insulation board. After completion, the air extraction device stops running, and the interior of the lower mold 11 and the upper mold 121 gradually returns to normal pressure. Then, the top hydraulic cylinder 131 pulls the lifting pressure head 12 to separate the upper mold 121 from the lower mold 11. At this time, the finished multi-layer insulation board is placed on the top of the lower mold 11, and the staff can remove it. This can achieve rapid application of glue to the single-layer boards 3 and reduce the time consumed in the glue application process.

[0025] like Figures 1 to 5 As shown, the conveying assembly includes multiple transmission rollers 232 that are rotatably connected at equal intervals on both sides inside the guide frame 2. Each side of the multiple transmission rollers 232 is fitted with a conveyor belt 233. The distance between the ends of the two conveyor belts 233 away from the lower mold 11 is less than the distance between the ends of the conveyor belts 233 that are close to the lower mold 11. A first motor 231 is installed at the top of the guide frame 2. The end of the shaft of the first motor 231 is fixedly connected to the top of the transmission rollers 232. When the single-layer board 3 moves inside the guide frame 2, the first motors 231 on both sides are started at the same time. The first motors 231 drive the transmission rollers 232 to rotate, and the transmission rollers 232 drive the conveyor belts 233 to roll. The conveyor belts 233 on both sides carry the single-layer board 3 to move above the lower mold 11. At this time, the single-layer board 3 can move inside the guide frame 2. When the single-layer board 3 moves to the position above the lower mold 11, the single-layer board 3 falls off due to the change in the spacing of the conveyor belts 233. This can realize automatic conveying and automatic unloading of the single-layer board 3.

[0026] like Figures 1 to 8 As shown, lifting blocks 222 are rotatably connected to both ends of the glue roller 22, fixing blocks 221 are fixed to both sides of the guide frame 2, and guide rods 223 are fixed to the top and bottom ends of the fixing blocks 221. The lifting blocks 222 are slidably connected to the outside of the guide rods 223, and springs 224 are sleeved on the outside of the guide rods 223. A pressure sensor 229 is fixed to the other end of the guide rods 223, and the pressure sensor 229 is fixedly connected to one end of the springs 224. When the single-layer board 3 passes between the glue-applying rollers 22, a movable lifting block 222 is set because the thickness of the single-layer board 3 is different. In the initial state, the gap between the glue-applying rollers 22 is at its minimum. Then, the single-layer board 3 is placed between the glue-applying rollers 22. The glue-applying rollers 22 are pushed and the lifting block 222 slides outside the guide rod 223. When the lifting block 222 slides, it squeezes the spring 224. After the spring 224 is squeezed, it applies pressure to the pressure sensor 229. After receiving the pressure signal, the pressure sensor 229 controls the glue-applying component to output glue. When the single-layer board 3 passes between the glue-applying rollers 22, the elastic force of the spring 224 drives the glue-applying rollers 22 to automatically reset, which can achieve adaptive adjustment based on the thickness of the single-layer board 3.

[0027] like Figures 1 to 8 As shown, guide plates 225 are fixed on the side of the upper and lower sets of lifting blocks 222 away from the guide frame 2, and the two guide plates 225 are symmetrically distributed about the horizontal center line of the fixed block 221. When the glue roller 22 needs to adapt to the thickness of the single-layer board 3, the single-layer board 3 is inserted between the connecting shafts 226. At this time, the single-layer board 3 pushes the connecting shaft 226 through the inclined surface of the connecting shaft 226. The connecting shaft 226 drives the lifting block 222 to move, which can make the glue roller 22 move automatically, making it easier to move the single-layer board 3 into the position between the glue rollers 22.

[0028] like Figures 1 to 8 As shown, each set of lifting blocks 222 is rotatably connected to the side of the connecting shaft 226, and the two ends of the glue brush roller 22 are fixed with the connecting shaft 226. The transmission rod 228 and the connecting shaft 226 are fitted with belts 227. Each time the glue roller 22 is used to apply glue to the outer surface of the single-layer board 3, the glue application assembly needs to pre-coat the surface of the glue roller 22, resulting in a blank area when the glue roller 22 coats the single-layer board 3. Therefore, pre-coating is required when the glue roller 22 coats the single-layer board 3. At this time, the single-layer board 3 first contacts the transmission rod 228 and drives the transmission rod 228 to roll. The transmission rod 228 drives the connecting shaft 226 through the belt 227 to make the glue roller 22 roll. At this time, the glue roller 22 can roll one revolution in advance for pre-coating. When the glue roller 22 contacts the single-layer board 3, its surface is already wetted with glue, preventing some areas of the single-layer board 3 from having no glue coating.

[0029] like Figures 1 to 8 As shown, the glue application assembly includes guide pipes 243 disposed above and below the glue brush roller 22. One end of the guide pipe 243 is connected to an external glue supply device. Multiple glue spraying pipes 244 are equally spaced on the side of the guide pipe 243 near the glue brush roller 22. When applying glue, the external glue supply device inputs glue into the guide pipe 243 through the pipeline. The guide pipe 243 outputs the glue evenly to the surface of the glue brush roller 22 through the glue spraying pipe 244. The glue brush roller 22 coats the glue onto the outer surface of the single-layer board 3 and stops outputting when not in use, which makes it easy to output glue to the surface of the glue brush roller 22.

[0030] like Figures 1 to 8 As shown, a fixed plate 24 is fixed to the top of the lifting block 222, and a rotating rod 241 is rotatably connected between the fixed plates 24. The outer side of the fixed plate 24 is fixedly connected to the top of the guide pipe 243. A J-shaped scraper 242 is fixed to one side of the rotating rod 241. A second motor 245 is installed on one side of one of the fixed plates 24. The output shaft of the second motor 245 is fixedly connected to one end of the rotating rod 241. When the guide tube 243 and the glue spray tube 244 are not needed, the second motor 245 is started to drive the rotating rod 241 to rotate. At this time, the rotating rod 241 drives the guide tube 243 and the glue spray tube 244 to rotate and separate from the glue brush roller 22, so that the glue spray tube 244 does not affect the rotation of the glue brush roller 22.

[0031] like Figures 1 to 8 As shown, a J-shaped scraper 242 is fixed on one side of the rotating rod 241. The second motor 245 can drive the rotating rod 241 to rotate and cause the J-shaped scraper 242 to stick to the surface of the glue roller 22. After use, glue residue remains on the surface of the glue roller 22. At this time, the rotating rod 241 rotates, causing the glue spray tube 244 to move away from the glue roller 22. Then, the J-shaped scraper 242 rotates to press against the surface of the glue roller 22. The glue roller 22 continues to rotate, which can scrape off the glue residue on the outside of the glue roller 22 by the J-shaped scraper 242, thereby preventing glue residue. When applying glue to the bottom single-layer board 3 and the top single-layer board 3, only one side needs to be coated. At this time, the second motor 245, which does not need to be coated, drives the rotating rod 241 to rotate, so that the J-shaped scraper 242 presses against the surface of the glue roller 22. When the single-layer board 3 drives the transmission rod 228 to rotate, the transmission rod 228 drives the glue roller 22 to rotate, so that the glue on the outer surface of the glue roller 22 that does not need to be coated is scraped off by the J-shaped scraper 242. This can realize the removal of glue from the outer surface of the glue roller 22 according to the usage requirements.

[0032] like Figures 1 to 6 As shown, both sides of the guide frame 2 are fixed with moving bars 23, and two support plates 21 are fixed on one side of the base 1. Two sets of first gears 213 are rotatably connected to one side of the support plate 21. The two sets of first gears 213 are meshed with the moving bars 23. A second gear 214 is fixed to the other end of the shaft of one of the first gears 213. Two lifting plates 211 are fixed on one side of the lifting head 12. A rack 212 is provided below one side of the lifting plate 211. When the lifting pressure head 12 pushes the upper mold 121 down, to prevent the glue roller 22 from obstructing the upper mold 121, the guide frame 2 needs to be moved away from below the upper mold 121. As the lifting pressure head 12 descends, it drives the lifting plate 211 downwards. When the lifting plate 211 moves downwards, it drives the rack 212, which in turn drives the second gear 214 to rotate. The second gear 214 then drives one of the first gears 213 to rotate. The first gear 213 drives the moving bar 23 to pull the guide frame 2 from above the lower mold 11 towards the support plate 21. After the second gear 214 passes the position of the rack 212, the lifting plate 211, as the lifting pressure head 12 descends, will no longer drive the guide frame 2 to move, thus preventing the guide frame 2 from... The upper mold 121 and the lower mold 11 will be blocked from closing. When the lifting head 12 drives the lifting plate 211 to move upward, the second gear 214 will first pass through the area above the lifting plate 211. At this time, the second gear 214 does not rotate. The lifting head 12 drives the upper mold 121 to separate from the lower mold 11, so that the multi-layer insulation board can be removed. Then the lifting head 12 drives the lifting plate 211 to continue to move upward. The lifting plate 211 drives the rack 212 to drive the second gear 214 to rotate in the opposite direction. At this time, the second gear 214 drives the moving bar 23 to move in the opposite direction through the first gear 213, so that the guide frame 2 is reset to the top of the lower mold 11. The position of the guide frame 2 can be automatically switched without affecting the closing of the lower mold 11 and the upper mold 121.

[0033] like Figures 1 to 2 As shown, four cylinders 111 are evenly spaced on the outer side of the lower mold 11. The cylinders 111 are fixedly connected to the base 1 via connecting rods, and a push plate 112 is fixed to the end of the output shaft of the cylinder 111. When multiple single-layer boards 3 are placed on the top of the lower mold 11, they may shift as they fall. At this time, the cylinder 111 pushes the push plate 112, and the multiple push plates 112 push the multiple single-layer boards 3 at the same time, squeezing them into the middle of the lower mold 11, thereby correcting the single-layer boards 3 that are not in the correct position.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
