Description

Technical Field

[0001] This invention relates to the field of pressing equipment for composite panels, and more specifically to a pressing device for thermoplastic composite panels. Background Technology

[0002] Composite panels refer to panels made of two or more materials. Regardless of the materials used in composite panels, they all need to be pressed together during the production process, which requires the use of pressing equipment.

[0003] In the actual use of a pressing device for thermoplastic composite panels, a large number of air bubbles will appear between the panels during the pressing and bonding process, resulting in uneven adhesive application. Therefore, the composite panels are prone to cracking during subsequent use. At the same time, if the adhesive in the freshly bonded composite panels is not completely dry, it is very easy to slip and shift under the action of external force, affecting product quality. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a pressing device for thermoplastic composite sheets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pressing device for thermoplastic composite sheets includes two supports. A first conveyor belt is installed on the top of the inner side wall of the supports. A second conveyor belt is installed between the outer walls of the two supports on opposite sides. A first mounting plate is installed above the second conveyor belt between the outer walls of the two supports on opposite sides. A through groove is opened on the top of the first mounting plate. Multiple support mechanisms are slidably installed inside the through groove. Each support mechanism includes a support plate slidably installed inside the through groove. Second clamps are slidably installed on both sides of the top of the support plate. A top plate is installed on the top of the supports through multiple support rods. Multiple pressing mechanisms that can move vertically are installed on the bottom of the top plate above each support mechanism.

[0007] Preferably, the inner two side walls of the first mounting plate are provided with first sliding grooves along the length direction, and multiple first electric sliders slide inside the first sliding grooves. An electric rotating rod is installed on one outer wall of the first electric slider, and one end of each of the two opposing electric rotating rods is connected to one end of the outer wall of the support plate.

[0008] Preferably, the top two ends of the support plate are provided with a fifth sliding groove along the width direction. Two fifth electric sliders are slidably installed inside the fifth sliding groove. The bottom of the second clamping piece is connected to the top of the corresponding two fifth electric sliders. Both ends of the outer wall of the two second clamping pieces on opposite sides are provided with protrusions. A second scraper that can move in the horizontal direction is provided on the outer wall of the protrusion. A third electric telescopic rod is provided between the second scraper and the corresponding protrusion.

[0009] Preferably, the pressing mechanism includes a third mounting plate and a plurality of first pressure plates. The top of the third mounting plate is connected to the bottom of the top plate via a seventh electric telescopic rod. A first mounting groove is provided at the bottom of the third mounting plate, and the plurality of first pressure plates are installed inside the first mounting groove.

[0010] Preferably, multiple nozzles are installed on opposite sides of the two first pressure plates inside the first mounting groove. First air plates are installed at both ends of the outer wall of each first pressure plate inside the first mounting groove. A storage box for storing glue is installed on the top of the top plate. The storage box is connected to the nozzles through a first hose. A first hot air box is also installed on the top of the top plate. The first hot air box is connected to the first air plate through a second hose.

[0011] Preferably, the bottom of the top plate is equipped with multiple clamping mechanisms located above the first conveyor belt. The clamping mechanism includes an L-shaped first connecting block, a fourth mounting plate, and two first clamping pieces. The top of the first connecting block is connected to the bottom of the top plate. A second connecting block that can move horizontally is installed on the outer wall of one side of the vertical end of the first connecting block. The bottom of the second connecting block is connected to the top of the fourth mounting plate. Both first clamping pieces are slidably installed on the bottom of the fourth mounting plate.

[0012] Preferably, a first electric telescopic rod is installed between the top of the first connecting block and the bottom of the top plate, a second electric telescopic rod is installed between the second connecting block and the first connecting block, and a fourth sliding groove is provided at the bottom of the fourth mounting plate along the length direction. Two fourth electric sliders are slidably installed inside the fourth sliding groove, and the bottom of the fourth electric slider is connected to the top of the corresponding first clamping piece.

[0013] Preferably, a laser rangefinder is slidably mounted on one end of the outer wall of each of the two brackets on opposite sides along the width direction, a first scraper that can move in the horizontal direction is slidably mounted on the outer wall of each of the two brackets on opposite sides along the length direction, and a limiting plate that can move in the vertical direction is mounted on the outer wall of each of the two brackets on opposite sides. The limiting plate is located on one side of the first scraper, and the first scraper is located between the limiting plate and the laser rangefinder.

[0014] Preferably, a second sliding groove is formed along the width direction at one end of the outer wall of each of the two brackets on opposite sides. A second electric slider is slidably installed inside the second sliding groove. One side of the outer wall of the second electric slider is connected to a corresponding laser rangefinder. A third sliding groove is formed along the length direction on the outer wall of each of the two brackets on opposite sides. A third electric slider is slidably installed inside the third sliding groove. A sixth electric telescopic rod is installed on one side of the outer wall of the third electric slider. The extended end of the sixth electric telescopic rod is connected to a corresponding first scraper. A fifth electric telescopic rod is also installed between the limiting plate and the corresponding bracket.

[0015] Preferably, a second mounting plate is installed on one end of the outer wall of the two supports on opposite sides, above the first conveyor belt. A second pressure plate that can move vertically is installed at the bottom of the second mounting plate. A fourth electric telescopic rod is installed between the second pressure plate and the second mounting plate. A second air box is installed at the top of the second mounting plate. Multiple second air outlets are opened at both ends of the bottom of the second mounting plate. The second air outlets are connected to the second air box through a third flexible hose.

[0016] The beneficial effects of this invention are reflected in:

[0017] 1. By setting up a third mounting plate and support plate, to prevent air bubbles in the adhesive between the two boards from affecting the bonding effect, a corresponding electric rotating rod can be used during the pressing process to make the support plate slightly reciprocate and squeeze. This ensures a more even distribution of adhesive between the two boards, and the mutual squeezing between the boards removes air bubbles in the adhesive, guaranteeing the quality of the composite board. Furthermore, during the placement of the second board, the friction between the two boards removes some air bubbles from the adhesive. When the electric rotating rod drives the support plate to rotate slightly, the air bubbles inside the adhesive are completely eliminated, preventing cracking of the composite board during subsequent use.

[0018] 2. By setting up a second scraper and a first air vane, after the composite board is dried, if some glue overflows from both sides of the composite board, the third mounting plate is moved downwards to press and fix the composite board. Then, the second clamping piece is moved inside the fifth slide groove by the fifth electric slider. After moving a certain distance, the second scraper is moved outwards by the third electric telescopic rod. One side of the second scraper can scrape and clean the glue overflowing from the side walls of the composite board, and the other side of the second scraper can scrape and clean the glue adhering to the outer wall of the corresponding second clamping piece, ensuring the cleanliness of the second clamping piece and preventing it from affecting the subsequent pressing effect of other boards. Throughout the operation, the first air vane continuously dries and heats the composite board to prevent the glue from not solidifying. At the same time, during the slow retraction of the third mounting plate, the first air vane can blow away impurities remaining on the top surface of the support plate, preventing them from affecting the subsequent pressing work.

[0019] 3. By setting up clamping and pressing mechanisms, when pressing three or more boards together, after the first two boards are glued and pressed, the glue needs to be dried and fixed, and the glue overflowing from both sides after the two boards are laminated needs to be cleaned up before the third board is laminated and pressed. This prevents the glue from solidifying during the pressing process and affecting the two second clamping pieces. When placing the board next time, the distance between the two second clamping pieces is slightly larger than the width of the board. There is a certain gap between the board and the second clamping pieces, which will affect the subsequent pressing operation. Therefore, product quality can still be guaranteed when laminating three or more boards. Attached Figure Description

A second conveyor belt 3 is installed between the outer walls of the two supports 1 on opposite sides. A first mounting plate 8 is installed above the second conveyor belt 3 between the outer walls of the two supports 1 on opposite sides. A through groove is opened on the top of the first mounting plate 8. Multiple support mechanisms are slidably installed inside the through groove.

Multiple first electric sliders 10 slide inside the first sliding grooves 9. An electric rotating rod 33 is installed on one side outer wall of the first electric slider 10. One end of each of the two opposing electric rotating rods 33 is connected to one end of the outer wall of the support plate 11.

[0039] As a technical optimization of the present invention, the top two ends of the support plate 11 are provided with a fifth sliding groove 38 along the width direction. Two fifth electric sliders 39 are slidably installed inside the fifth sliding groove 38. The bottom of the second clamping piece 37 is connected to the top of the corresponding two fifth electric sliders 39. Both ends of the outer wall of the two second clamping pieces 37 on opposite sides are provided with protrusions 34. A second scraper 36 that can move in the horizontal direction is provided on one side of the outer wall of the protrusion 34. A third electric telescopic rod 35 is installed between the second scraper 36 and the corresponding protrusion 34.

[0040] As a technical optimization of the present invention, the pressing mechanism includes a third mounting plate 21 and a plurality of first pressure plates 30. The top of the third mounting plate 21 is connected to the bottom of the top plate 5 through a seventh electric telescopic rod. A first mounting groove is provided at the bottom of the third mounting plate 21, and the plurality of first pressure plates 30 are installed inside the first mounting groove.

[0041] As a technical optimization of the present invention, multiple nozzles 31 are installed inside the first mounting groove on opposite sides of the two first pressure plates 30. First air plates 32 are installed at both ends of the outer wall of each first pressure plate 30 inside the first mounting groove. A storage tank 6 for storing adhesive is installed on the top of the top plate 5. The storage tank 6 is connected to the nozzles 31 via a first flexible hose. A first hot air box 7 is also installed on the top of the top plate 5, and the first hot air box 7 is connected to the first air plate 32 via a second flexible hose. It should be noted that a pump is also installed between the storage tank 6 and the first hot air box 7. The pump's inlet is connected to the storage tank 6, and its outlet is connected to the nozzles 31. After the pump is started, the nozzles 31 can spray adhesive. The pump is a common driving device and is therefore not shown in the accompanying drawings.

[0042] As a technical optimization of the present invention, the bottom of the top plate 5 is equipped with a plurality of clamping mechanisms above the first conveyor belt 2. The clamping mechanism includes an L-shaped first connecting block 25, a fourth mounting plate 22 and two first clamping pieces 23. The top of the first connecting block 25 is connected to the bottom of the top plate 5. A second connecting block 27 that can move in the horizontal direction is installed on the outer wall of one side of the vertical end of the first connecting block 25. The bottom of the second connecting block 27 is connected to the top of the fourth mounting plate 22. The two first clamping pieces 23 are slidably installed on the bottom of the fourth mounting plate 22.

[0043] As a technical optimization of the present invention, a first electric telescopic rod 24 is installed between the top of the first connecting block 25 and the bottom of the top plate 5, and a second electric telescopic rod 26 is installed between the second connecting block 27 and the first connecting block 25. A fourth sliding groove 28 is formed along the length direction at the bottom of the fourth mounting plate 22. Two fourth electric sliders 29 are slidably installed inside the fourth sliding groove 28, and the bottom of the fourth electric sliders 29 is connected to the top of the corresponding first clamping piece 23. During the pressing process, to prevent air bubbles in the adhesive between the two boards from affecting the bonding effect, the support plate 11 can be slightly reciprocated and squeezed during the pressing process by the corresponding electric rotating rod 33. This allows the adhesive between the two boards to be distributed more evenly, and the mutual squeezing between the boards can expel air bubbles in the adhesive, ensuring the product quality of the composite board. In addition, during the placement of the second board, the friction between the two boards can remove some air bubbles in the glue. When the electric rotating rod 33 drives the support plate 11 to rotate slightly, the air bubbles inside the glue will be completely removed, preventing the composite board from cracking during subsequent use.

[0044] As a technical optimization of the present invention, a laser rangefinder 16 is slidably installed on one end of the outer wall of each of the two brackets 1 on opposite sides along the width direction. A first scraper 19 that can move in the horizontal direction is slidably installed on the outer wall of each of the two brackets 1 on opposite sides along the length direction. A limiting plate 20 that can move in the vertical direction is installed on the outer wall of each of the two brackets 1 on opposite sides. The limiting plate 20 is located on one side of the first scraper 19, and the first scraper 19 is located between the limiting plate 20 and the laser rangefinder 16.

[0045] As a technical optimization of the present invention, a second sliding groove 14 is provided at one end of the outer wall of each of the two supports 1 on opposite sides along the width direction. A second electric slider 15 is slidably installed inside the second sliding groove 14. One side of the outer wall of the second electric slider 15 is connected to a corresponding laser rangefinder 16. A third sliding groove 17 is provided at one end of the outer wall of each of the two supports 1 on opposite sides along the length direction. A third electric slider 18 is slidably installed inside the third sliding groove 17. A sixth electric telescopic rod 43 is installed on one side of the outer wall of the third electric slider 18. The protruding end of the sixth electric telescopic rod 43 is connected to a corresponding first scraper 19. A fifth electric telescopic rod 42 is also installed between the limiting plate 20 and the corresponding support 1. When it is necessary to inspect the composite board, the laser rangefinder 16 can be slid inside the second sliding groove 14 according to the standard thickness of the composite board. Then, the laser rangefinder 16 is used to inspect the processed composite board. If the composite board is qualified, it is output through the second conveyor belt 3 for packaging. If it is unqualified, the unqualified composite board is removed manually or by an external robot and placed away, which affects the overall quality of the product.

[0046] As a technical optimization of the present invention, a second mounting plate 12 is installed on one end of the outer wall of the two supports 1 on opposite sides above the first conveyor belt 2. A second pressure plate 40 that can move in the vertical direction is installed at the bottom of the second mounting plate 12. A fourth electric telescopic rod 41 is installed between the second pressure plate 40 and the second mounting plate 12. A second air box 13 is installed at the top of the second mounting plate 12. Multiple second air outlets 44 are opened at both ends of the bottom of the second mounting plate 12. The second air outlets 44 are connected to the second air box 13 through a third flexible hose.

[0047] In this invention, when a user needs to use the device to press the composite material together, the device is moved to the designated location and powered on, and the pressing operation can begin.

[0048] When the pressing operation begins, the plates to be pressed are first placed manually or by an external robotic arm on top of the two first conveyor belts 2. After placement, the first electric telescopic rods 24 are extended downwards so that the first clamping plates 23 are positioned above the corresponding plates to be used. Then, the two first clamping plates 23 slide inside the fourth groove 28 at the bottom of the fourth mounting plate 22 via the corresponding fourth electric sliders 29, clamping and fixing the plates to be used. After fixing, the first electric telescopic rods 24 are adjusted adaptively and the second electric telescopic rods 26 are extended outwards. Finally, the plates to be used are placed on the support plate 11, which is in a straight line with the two first clamping plates 23. After placement, the first clamping plates 23 are returned to their original positions. Figure 4 The device in the indicated state can wait for the next clamping operation.

[0049] When the sheet material to be used is placed above the support plate 11, the fifth electric slider 39 is slidably adjusted inside the fifth slide groove 38 at the top of the corresponding support plate 11. The two second clamping pieces 37 are moved by the fifth electric slider 39. The two second clamping pieces 37 can clamp and fix the two sides of the sheet material, which is convenient for subsequent pressing. Then, the third mounting plate 21 is moved downwards via the seventh electric telescopic rod. When the third mounting plate 21 moves above the board, each nozzle 31 can spray glue for bonding the board. The simultaneous spraying of multiple nozzles 31 can make the sprayed glue more evenly cover the top of the board. Then, the third mounting plate 21 can be retracted via the seventh electric telescopic rod. Then, the above clamping operation is repeated on the other side of the clamping mechanism. The other board to be used is clamped and fixed by the two first clamping pieces 23 on the other side. The board to be used is placed on top of the board that has been coated with glue. Then, the corresponding clamping mechanism is retracted. During the placement of the other board, the fifth electric slider 39 can be slid outwards, so that the two second clamping pieces 37 temporarily stop clamping the board after the glue has been applied, which is convenient for the subsequent placement of the board. When the other board is placed on top of the board after the glue has been applied, the two second clamping pieces 37 clamp and fix the two boards again. While the boards are being laminated, the two boards move relative to each other, so that the glue is applied more evenly and the laminated board is prevented from cracking during the subsequent use of the laminated board. Then, the corresponding third mounting plate 21 is moved downwards, and the two panels are pressed down by the first pressure plates 30 at the bottom of the third mounting plate 21. Under the joint pressure of the first pressure plates 30 and the corresponding support plates 11, the two panels can be glued and pressed together. During the pressing process of the two panels, the second clamping pieces 37 on both sides can abut and fix the sides of the two panels. This not only ensures that the position between the panels does not shift during the pressing process, but also prevents glue from overflowing from the sides of the panels during the pressing process, further improving the product quality of the composite panel.

[0050] During the lamination process, to prevent air bubbles in the adhesive between the two boards from affecting the bonding effect, the support plate 11 can be slightly rotated and squeezed by the corresponding electric rotating rod 33 during the lamination process. This ensures a more even distribution of adhesive between the two boards, and the mutual squeezing between the boards removes air bubbles in the adhesive, ensuring the quality of the composite board. Furthermore, during the placement of the second board, the friction between the two boards removes some air bubbles from the adhesive. When the electric rotating rod 33 drives the support plate 11 to rotate slightly, the air bubbles inside the adhesive are completely eliminated, preventing cracking of the composite board during subsequent use.

[0051] After extrusion is completed, the third mounting plate 21 is contracted so that it is positioned above the composite board. Then, the first hot air box 7 is activated, and the composite board is dried through the first air plate 32 at the bottom of the third mounting plate 21, so that the adhesive can solidify quickly. During the drying process, the two second clamping pieces 37 can limit and fix the composite board to prevent it from sliding and shifting under the action of external force when the adhesive in the newly glued composite board is not completely dry, thus affecting the product quality.

[0052] After the composite board is dried, if some glue overflows from both sides of the composite board, first move the third mounting plate 21 downwards to press and fix the composite board. Then, move the second clamping piece 37 inside the fifth slide groove 38 via the fifth electric slider 39. After moving a certain distance, move the second scraper 36 outwards via the third electric telescopic rod 35. One side of the second scraper 36 can scrape and clean the glue overflowing from both sides of the composite board. At the same time, the other side of the second scraper 36 can scrape and clean the glue adhering to the outer wall of the corresponding second clamping piece 37, ensuring the cleanliness of the second clamping piece 37 and preventing it from affecting the pressing effect of the remaining boards. After the scraping and cleaning is completed, the second scraper 36 is retracted and the composite board is held and fixed by the two second clamps 37. The corresponding third mounting plate 21 is slowly retracted. During the entire pressing process, the first air plate 32 continuously dries and heats the composite board to prevent the glue from not solidifying. At the same time, during the slow retraction of the third mounting plate 21, the first air plate 32 can blow away the impurities remaining on the top surface of the support plate 11 to prevent them from affecting the subsequent pressing work.

[0053] After the composite board is pressed, the support plate 11 can be rotated by the electric rotary rod 33 until the top of the support plate 11 faces the top of the second conveyor belt 3 and the two are in a parallel state. Then the two second clamping plates 37 stop clamping the composite board and the composite board falls to the top of the second conveyor belt 3 for packaging.

[0054] It should be noted that if more composite panels need to be stacked for lamination, the above-mentioned panel placement, glue application, and pressing operations can be repeated to press the subsequent panels together. Multiple clamping mechanisms on both sides and the corresponding support plates 11 can work together for feeding and pressing. The entire device operates in multi-station operation during actual use, further improving the production efficiency of composite panels. Furthermore, when pressing three or more panels, after applying glue and pressing the first two panels, the glue needs to be dried and fixed, and any excess glue on both sides after lamination should be cleaned before pressing the third panel. This prevents the solidified glue from affecting the two second clamping plates 37 during pressing. If the distance between the two second clamping plates 37 is slightly greater than the width of the panel when placing the next panel, a gap will exist between the panel and the second clamping plates 37, affecting subsequent pressing operations and making it impossible to guarantee that the panel will not shift during pressing, thus affecting product quality. Therefore, it is necessary to clean the glue again before pressing the next panel. In summary, when using the above operations to composite three or more plates, the overall equipment can still guarantee the quality of the product.

[0055] When the composite board moves above the second conveyor belt 3, two limiting plates 20 are moved outward by the corresponding fifth electric telescopic rod 42 according to the length of the composite board. The two limiting plates 20 can limit and guide the composite board during its movement above the second conveyor belt 3 to facilitate subsequent inspection operations.

[0056] When it is necessary to clean the glue overflowing from both ends of the outer wall of the composite board, when the composite board to be cleaned moves to below the second pressure plate 40, the second conveyor belt 3 is stopped first, and then the second pressure plate 40 is moved downward by the fourth electric telescopic rod 41. The second pressure plate 40 can press and fix the composite board. After fixing, the first scraper 19 is moved outward by the corresponding sixth electric telescopic rod 43 so that both first scrapers 19 can contact both ends of the composite board. Then, the third electric slider 18 slides inside the corresponding third slide groove 17 so that the first scrapers 19 can scrape and clean the glue overflowing from both ends of the composite board, ensuring product quality while maintaining aesthetics. Then, the second pressure plate 40 is retracted and the second conveyor belt 3 is started. During the retraction of the second pressure plate 40, the second air box 13 is activated. The second air box 13 activates the second air outlet 44 to continuously blow air outward, thereby blowing away impurities attached to the outside of the composite board, and such as... Figure 2 , 3 As shown, the top of the second conveyor belt 3 has multiple through holes, allowing impurities to fall out from inside the through holes.

[0057] When it is necessary to test the composite board, the laser rangefinder 16 can be slid through the second electric slider 15 inside the second slide groove 14 according to the standard thickness of the composite board. Then, the laser rangefinder 16 can be used to test the processed composite board. If the composite board is qualified, it will be output through the second conveyor belt 3 for packaging. If it is unqualified, the unqualified composite board will be removed manually or by an external robot and placed away, which will affect the overall quality of the product.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
