Description

Technical Field

[0001] The present invention relates to the technical field of sandwich panel processing, and more particularly to a pressing machine for sandwich panel production and a method of using the same. Background Art

[0002] Metal-faced sandwich panels are a common building material, typically consisting of two metal panels, top and bottom, with a core material filling the middle. They offer lightweight, high strength, thermal insulation, sound insulation, and fire resistance, making them widely used in industries such as construction, transportation, and refrigeration. The upper and lower panels are typically made of color-coated steel, aluminum, or stainless steel, while the core material is typically rock wool, polyurethane, or glass wool. When using rock wool or glass wool as the core material, adhesive bonding and lamination are required, as these materials are inherently non-sticky.

[0003] In the prior art, when scraping off the adhesive that overflows during the sandwich panel lamination process, the scraping is usually done after the sandwich panels are completely laminated. At this point, the adhesive has already solidified, making scraping off laborious and easily damaging the edges of the sandwich panels.

DETAILED DESCRIPTION

[0036] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0037] like Figures 1-10As shown, the pressing machine for sandwich panel production includes: a base 1, four groups of clamping components 2, a pressing component 3 and four groups of scraping components 4. It should be noted that the sandwich panels applicable to this application are sandwich panels with a rectangular structure. Among them, the base 1 mainly plays the role of support and installation, and can provide a carrier for installation and support of the corresponding components. For example, the sandwich panel can be placed on the base 1 for pressing operations. The four groups of clamping components 2 are mainly used to limit the four side walls of the sandwich panel placed on the base 1, so as to ensure that the sandwich panel will not be displaced during the pressing process, which is conducive to improving the quality of pressing. The pressing component 3 is mainly used to press the sandwich panel to ensure that the structure of the sandwich panel is more reliable and stable. It should be noted that the pressing component 3 usually needs to go through three stages of pre-pressing, hot pressing and holding pressure in the process of pressing the sandwich panel. Pre-pressing is to initially fix the stacking structure of the sandwich panel to prevent displacement and ensure initial contact of the adhesive. The hot pressing stage is to foam the core material in the sandwich panel or accelerate the curing of the adhesive. The pressure holding stage is to maintain the pressure on the sandwich panel until the adhesive is completely cured. The four sets of scraping components 4 are used to scrape off the adhesive overflowing from the edge of the sandwich panel when it is squeezed, so as to make the edge of the sandwich panel more flat.

[0038] Specifically, if Figure 1 As shown, the base 1 includes a top plate 11, a bottom plate 13, and a plurality of connecting columns 12, each of which is fixedly connected to the top plate 11 and the bottom plate 13 at both ends. Vertically, the top plate 11 has a square cross-section and is positioned above the bottom plate 13. The top plate 11 is primarily used to support the sandwich panels. The plurality of connecting columns 12 are spaced apart to provide more comprehensive support points for the top plate 11, thereby making the top plate 11 more stable and providing better support for the sandwich panels.

[0039] In addition, if Figure 1 and Figure 3 As shown, four groups of clamping assemblies 2 are arranged on the base 1 for selectively fixing the four sides of the sandwich panel. It should be noted that the four clamping assemblies 2 can be respectively arranged in four directions of the base 1 so as to better correspond to the four side walls of the sandwich panel. Specifically, the clamping assembly 2 includes: a first cylinder 21, an L-shaped connecting rod 22 and a clamping plate 23. The first cylinder 21 is fixedly connected to the bottom of the top plate 11, the telescopic end of the first cylinder 21 is fixedly connected to one end of the L-shaped connecting rod 22, and the other end of the L-shaped connecting rod 22 is fixedly connected to the clamping plate 23, and the clamping plate 23 is located above the top plate 11. Fixedly connecting the first cylinder 21 to the bottom of the top plate 11 can save space and avoid interference between the first cylinder 21 and other components, making it more convenient to use. The four clamping plates 23 are respectively arranged parallel to the four sides of the corresponding sandwich panel.

[0040] When in use, it should be noted that, in the initial state, the centers of the four clamping plates 23 are at the same distance from the center of the top plate 11. In this way, after the sandwich panel is placed on the top plate 11, it is only necessary to start the four first cylinders 21 at the same time. The four first cylinders 21 drive the corresponding clamping plates 23 to move the same distance through the corresponding L-shaped connecting rods 22 to achieve the positioning of the sandwich panel, thereby improving the error rate during the initial placement of the sandwich panel and making it easier to control.

[0041] In addition, if Figures 1-4 and Figure 8 As shown, the pressing assembly 3 is mounted on the base 1. The pressing assembly 3 comprises a drive assembly 31, multiple pressure rods 32, a pressure plate 33, and a vibration damping assembly 34. The drive assembly 31 primarily provides power for the movement of the pressure rods 32 and pressure plate 33. The pressure rods 32 are primarily used to transmit power. The pressure plate 33 primarily contacts and applies pressure to the sandwich panel. The vibration damping assembly 34 primarily absorbs vibrations on the pressure plate 33, thereby protecting the pressure plate 33 and ensuring a more stable clamping of the sandwich panel.

[0042] Specifically, the drive assembly 31 is mounted on the base 1 and includes a bracket 311, a hydraulic cylinder 312, and a drive plate 313. The bracket 311 comprises three vertical sections and one horizontal section. The bottoms of the three vertical sections are fixedly connected to the bottom plate 13, while the tops of the three vertical sections are fixedly connected to the horizontal section. The three vertical sections are spaced 90 degrees apart horizontally, which provides a more stable structure for the bracket 311. The open side of the bracket 311 facilitates placement of the sandwich panel onto the top plate 11.

[0043] The fixed end of the hydraulic cylinder 312 is connected to the bottom of the horizontal portion, and the telescopic end of the hydraulic cylinder 312 is fixedly connected to the drive plate 313. The ends of the multiple pressure rods 32 are respectively fixedly connected to the drive plate 313 and the pressure plate 33 in the drive assembly 31. It should be noted that the telescopic end of the first cylinder 21 is fixedly connected to the center of the drive plate 313, and the multiple pressure rods 32 are arranged in a circular array around the center of the drive plate 313. At the same time, the multiple pressure rods 32 are also distributed around the central circular array of the pressure plate 33. The arrangement of multiple pressure rods 32 can transmit the power of the first cylinder 21 to the pressure plate 33 from multiple directions, so that when the pressure plate 33 presses the sandwich panel, the force on the pressure plate 33 and the sandwich panel is more uniform, which is beneficial to protecting the pressure plate 33 and also can better press the sandwich panel.

[0044] Furthermore, in the vertical direction, the cross-sectional dimensions of the pressing plate 33 are identical to those of the sandwich panel. If the cross-sectional dimensions of the pressing plate 33 are smaller than those of the sandwich panel, the pressing plate 33 cannot fully compress the sandwich panel, affecting the sandwich panel's pressing effect. If the cross-sectional dimensions of the pressing plate 33 are larger than those of the sandwich panel, it is inconvenient to scrape off any adhesive that overflows from the sandwich panel's sidewalls during the pressing process. After the pressing is complete, the adhesive will have solidified and become difficult to handle. Therefore, the cross-sectional dimensions of the pressing plate 33 are identical to those of the sandwich panel. This allows for scraping off any adhesive that overflows from the sandwich panel's sidewalls during the pressing process, making it more convenient to use.

[0045] In addition, if Figure 1 and Figure 2 As shown, four sets of scraper assemblies 4 are positioned on the pressure plate 33, respectively used to scrape off any adhesive that overflows from the four edges of the sandwich panel. It should be noted that the four scraper assemblies 4 can be positioned in four directions on top of the pressure plate 33, corresponding to the four sidewalls of the sandwich panel, facilitating the scraping of adhesive that overflows from the sidewalls. Positioning the scraper assemblies 4 on the pressure plate 33 allows them to scrape off any adhesive that overflows from the sidewalls of the sandwich panel at any time during the lamination process, preventing interference between the scraper assemblies 4 and other components on the top plate 11 and providing greater convenience.

[0046] Specifically, the scraping assembly 4 includes a cutter 41, a cutter holder 42, a second cylinder 43, and an L-shaped mounting bracket 44. The mounting bracket 44 is fixedly connected to the top of the pressing plate 33. The fixed end of the second cylinder 43 is fixedly connected to the mounting bracket 44, and the telescopic end of the second cylinder 43 is fixedly connected to the cutter holder 42. The cutter holder 42 is fixedly connected to the top of the cutter 41. Driven by the second cylinder 43, the cutter 41 moves up and down along the edge of the pressing plate 33. Because the vertical cross-sectional dimensions of the pressing plate 33 are the same as those of the sandwich panel, placing the cutter 41 against the edge of the pressing plate 33 allows for more clean scraping of adhesive that overflows from the sidewalls of the sandwich panel.

[0047] In addition, if Figure 5 and Figure 9As shown, a quadrilateral annular groove 111 is provided on the upper surface of the top plate 11, and the four inner side walls of the annular groove 111 are respectively flush with the four outer side walls of the pressure plate 33. The annular groove 111 is mainly used to collect the adhesive after scraping, which makes collection more convenient and also facilitates the subsequent processing of the adhesive. The four inner side walls of the annular groove 111 are respectively flush with the four outer side walls of the pressure plate 33. Since the cross-sectional dimensions of the pressure plate 33 are the same as the cross-sectional dimensions of the sandwich panel in the vertical direction, the four inner side walls of the annular groove 111 are also flush with the four side walls of the sandwich panel. In this way, after the tool 41 scrapes off the adhesive overflowing from the side wall of the sandwich panel, the scraped adhesive can fall directly into the annular groove 111 when it falls off. The adhesive attached to the tool 41 can be manually scraped off later.

[0048] In addition, if Figure 6 and Figure 9 As shown, a through hole 1111 is provided in the center of the bottom of each side of annular groove 111. Each side of annular groove 111 is provided with inclined surfaces on both sides of through hole 1111, and the side of the inclined surface closest to through hole 1111 is lower than the side of the inclined surface farther from through hole 1111. Once adhesive falls into annular groove 111, it can slide along the inclined surfaces to through hole 1111 under the action of gravity or manual operation, and then be discharged through through hole 1111, making it more convenient to use.

[0049] Further, if Figure 1 and Figure 6 As shown, water inlet pipes 5 are provided at the four corners of the annular groove 111. Two water outlet holes are provided on the water inlet pipe 5, and the two water outlet holes are respectively arranged toward two adjacent sides of the annular groove 111. The water inlet pipe 5 can be placed vertically, and the top of the water inlet pipe 5 is connected to an external water source.

[0050] During use, before starting the scraper assembly 4, water can be filled into the water inlet pipe 5 first. The water in the four water inlet pipes 5 will flow through the entire annular groove 111 and soak the annular groove 111. This can effectively reduce the viscosity between the adhesive and the annular groove 111, making it easier for the adhesive to slide in the annular groove 111. Moreover, after the adhesive falls into the annular groove 111, the flow of water will further drive the adhesive to move toward the corresponding through hole 1111, facilitating the discharge of the adhesive.

[0051] In addition, if Figure 4 and Figure 8As shown, the vibration reduction assembly 34 includes a damper 341 and a connecting assembly 342. The connecting assembly 342 includes a connecting ring 3421, multiple connecting plates 3422, multiple fixing members 3432, and a damping adjustment assembly 3423. The multiple connecting plates 3422 correspond one-to-one with the multiple pressure rods 32. The multiple connecting plates 3422 are fixedly connected to the outer wall of the connecting ring 3421 and are arranged in a circular array around the center of the connecting ring 3421. The connecting plates 3422 are respectively provided with first sliding holes 3424 and second sliding holes 3425 in the vertical and horizontal directions. The pressure rods 32 are also provided with third sliding holes 321 in the horizontal direction. The pressure rods 32 pass through the corresponding first sliding holes 3424. The fixing members 3432 connect the connecting plates 3422 to the corresponding pressure plates 33 through the second sliding holes 3425 and the third sliding holes 321. The damping adjustment component 3423 is connected to the other end of the damper 341 and is used to adjust the angle of the damper 341 .

[0052] Specifically, the damping adjustment assembly 3423 includes a screw 3426, a nut seat 3427, and a knob 3428. The two ends of the screw 3426 are rotatably connected to the inner wall of the connecting ring 3421. One end of the screw 3426 extends outside the connecting ring 3421 and is fixedly connected to the knob 3428. The nut seat 3427 is threadedly connected to the screw 3426 and rotatably connected to the other end of the damper 341. It should be noted that the first sliding hole 3424, the second sliding hole 3425, and the third sliding hole 321 are all elongated structures, and the fixing member 3432 can drive the corresponding connecting plate 3422 to move up and down within the corresponding third sliding hole 321.

[0053] When in use, when the angle of the damper 341 needs to be adjusted, the knob 3428 needs to be rotated, and the knob 3428 will drive the screw 3426 to rotate. The rotation of the screw 3426 will drive the nut seat 3427 to move along the axial direction of the screw 3426. The movement of the nut seat 3427 will drive the damper 341 to deflect. At this time, the height of the top of the damper 341 also changes, and the damper 341 will drive the connecting ring 3421 to move in the vertical direction through the damping adjustment component 3423. The pressure plate 33 is moved so that the connecting plate 3422 moves up and down. When the angle of the damper 341 is fixed, the position of the connecting plate 3422 in the vertical direction is also fixed. Therefore, the vibration on the pressure plate 33 is transmitted to the damper 341 through the pressure rod 32, the connecting plate 3422, the connecting ring 3421 and the damping adjustment assembly 3423. The damper 341 absorbs the vibration on the pressure plate 33, thereby protecting components such as the pressure plate 33 and the pressure rod 32, and the sandwich panel can be pressed more stably.

[0054] As an optional embodiment, the damping adjustment assembly 3423 further includes: two mounting plates 3429, a guide rod 3430, and a guide seat 3431. The two mounting plates 3429 are symmetrically fixedly connected to the top of the connecting ring 3421. The two ends of the guide rod 3430 are respectively fixedly connected to the two mounting plates 3429. The guide seat 3431 is fixedly connected to the top of the nut seat 3427 and is slidably connected to the guide rod 3430. The nut seat 3427 is connected to the guide rod 3430 through the guide seat 3431, which can prevent the nut seat 3427 from rotating with the screw 3426, thereby ensuring more stable movement of the nut seat 3427 and facilitating adjustment of the angle of the damper 341.

[0055] A method for using a pressing machine for producing sandwich panels comprises the following steps:

[0056] Step 1: According to the size of the sandwich panel to be processed and the pressure required to be applied to the sandwich panel, the angle of the damper 341 is adjusted using the angle adjustment assembly.

[0057] Step 2: Place the cleaned sandwich panel on the top plate 11, and then start the four groups of clamping components 2 to clamp the four side walls of the sandwich panel.

[0058] Step three: pre-pressing. Start the pressing assembly 3 to gradually move the pressing plate 33 closer to the sandwich panel and pre-press the sandwich panel.

[0059] Step 4: Hot Pressing: The pressing plate 33 continues to apply pressure to the sandwich panel. At this point, the four clamping assemblies 2 are activated to release the clamping of the sandwich panel. It should be noted that during the hot pressing process, a heating source, such as a heating wire, is typically provided within the pressing plate 33. This is prior art and is not specifically described in this application.

[0060] Step 5: Maintaining pressure: maintaining the pressure of the pressing plate 33 on the sandwich panel for a predetermined period of time to allow the adhesive to fully solidify.

[0061] Step 6: Fill water into the four water inlet pipes 5 to wet the bottom of the annular groove 111 .

[0062] Step 7: Start the four sets of glue scraping components 4 to cut the adhesive overflowing from the edge of the sandwich panel into the annular groove 111 and discharge it through the corresponding through holes 1111 .

[0063] The above describes the embodiments of this embodiment, but this embodiment is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
