[0002] SPC material is an environmentally friendly modified plastic, its main components are polyvinyl chloride and curing agent, made by high-temperature extrusion and cooling and shaping. SPC material has the characteristics of high strength, not easy to deform, high temperature resistance, acid and alkali resistance, etc.

[0003] At present, when using SPC materials to make cabinet panels, multi-layer solid pressing is often used, that is, the panels are made by stacking multiple layers of board cores. However, the sound insulation performance of the panels made in this way is poor. When making cabinet panels, there are still the following shortcomings:

[0004] It is difficult to place the lower panel, the sound insulation frame and the upper panel in a vacuum state, resulting in air still existing between the upper panel and the lower panel, which is bound to affect the sound insulation performance of the manufactured cabinet panel.

DETAILED DESCRIPTION

[0045] The embodiments of the present invention are described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0046] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms, "connection" and "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "connection" can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed" means that they are connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present invention, such as "inside", "outside", "top", "bottom", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.

[0047] Example 1: Reference Figure 1-Figure 10A soundproof and heat-insulating SPC cabinet panel of this embodiment includes a lower panel 20 and an upper panel 22. The lower panel 20 is fixedly connected to the upper panel 22 through a soundproof frame 21, and a heat-insulating film 23 is applied on the side of the lower panel 20 and the upper panel 22 away from each other.

[0048] S1, cutting and cleaning: First, the lower panel 20 and the upper panel 22 are cut according to the design size in advance to ensure the size is accurate. After cutting, the surface of the lower panel 20 and the upper panel 22 is thoroughly cleaned to remove dust, oil and other impurities on the surface to ensure the quality of subsequent processing.

[0049] S2. Assembly preparation: Place the cut and cleaned lower panel 20, soundproof frame 21 and upper panel 22 in the press according to a predetermined order. The press includes a processing box 2, and a plurality of columns 1 are symmetrically fixedly installed on the bottom of the processing box 2 to provide stable support. Guide grooves 16 are fixedly installed on the inner walls on both sides of the processing box 2, and a slide bar 17 is slidably connected in the guide groove 16. The tops of the two slide bars 17 extend into the processing box 2 and jointly support the first support plate 18. A door panel 3 is fixedly installed on one side of the first support plate 18, and the door panel 3 is sealed and clamped with the opening of the processing box 2 to ensure that the gas in the processing box 2 can be effectively extracted.

[0050] S3, vacuuming: start the suction mechanism of the press, which is installed on one side of the top of the processing box 2 and is connected to the inside of the processing box 2 through a pipeline. The suction mechanism starts to work, and the air in the processing box 2 is sucked out, so that the lower panel 20, the sound insulation frame 21 and the upper panel 22 can be in a vacuum state when they are assembled, thereby eliminating the influence of air on the pressing process.

[0051] S4, pressing and forming: Use the pressing mechanism of the press machine to provide downward pressure on the upper panel 22. The pressing mechanism passes through the top inner wall of the processing box 2 and is connected to the top inner wall of the processing box 2. Its power source can be a hydraulic cylinder or a pneumatic cylinder, etc. The pressing mechanism moves by driving the pressing mechanism. The pressing mechanism includes a pressing box 19 fixedly mounted on the top of the first support plate 18, and the cabinet panel is arranged in the pressing box 19. The pressing mechanism also includes two fixing components symmetrically installed on the support frame 24, and the fixing components are used to attract and fix the upper panel 22. Under the action of the pressing mechanism, the two fixing components move downward, driving the upper panel 22 and the sound insulation frame 21 to be pressed until an integrated cabinet panel is formed.

[0052] S5. Static treatment: Take out the pressed integrated cabinet panel from the press and let it stand for a while to release the stress inside the cabinet panel and ensure the stability and durability of the cabinet panel.

[0053] S6, laminating treatment: After the static standing is completed, the cabinet board is placed in a laminating machine, and a layer of thermal insulation film 23 is applied on the side of the lower panel 20 and the upper panel 22 away from each other. The thermal insulation film 23 can be applied by hot pressing or gluing to ensure a close fit between the thermal insulation film 23 and the cabinet board.

[0054] In the specific structure of the press, the fixed assembly includes two pressing head rods 25 that penetrate the support frame 24 and are slidably connected to the support frame 24. The pressing head rods 25 are sleeved with a second compression spring 35 located above the support frame 24 to provide an upward elastic force. A suction cover 26 is fixedly installed at the bottom end of the pressing head rod 25, and a rubber skirt 27 is fixedly installed at the bottom opening position of the suction cover 26 to increase the contact area and sealing with the upper panel 22. Both suction covers 26 are used to suck the upper panel 22, and their interiors are connected to the suction cover 29 through the mounting tube 28. A retaining ring 30 is fixedly installed in the suction cover 29, and a first piston plate 31 is sealingly and slidably connected in the suction cover 29, and a pull rod 32 is fixedly installed on one side of the first piston plate 31. After the upper panel 22 is attached to the four rubber skirts 27, the pull rods 32 are pulled at the same time to bring the corresponding two pull rods 32 closer to each other, thereby driving the first piston plate 31 to move, and the gas in the suction cover 26 is sucked into the suction cover 29, forming a negative pressure state. Afterwards, the threaded disk 33 and the threaded cover 34 are threadedly connected to lock the position of the pull rod 32, so that the two suction covers 26 maintain a constant suction force, and the upper panel 22 is braked stably. Under the downward pressure of the pressing mechanism, the four pressing rods 25 can move downward, driving the upper panel 22 and the sound insulation frame 21 to be stably pressed.

[0055] In the processing technology, the pressing mechanism is one of the core components, which is responsible for pressing the upper panel 22 and the sound insulation frame 21. The pressing mechanism includes a fixed cover 36 fixedly mounted on the top inner wall of the processing box 2, and a moving rod 37 is slidably connected through the top inner wall of the fixed cover 36. A pressing frame 38 is fixedly mounted on the bottom end of the moving rod 37, and pressing rods 39 are fixedly mounted at the four corners of the bottom of the pressing frame 38. These pressing rods 39 are in active contact with the corresponding pressing head rods 25. The moving rod 37 is sleeved with a tension spring 40 located in the fixed cover 36, and the top and bottom ends of the tension spring 40 are fixedly connected to the top inner wall of the fixed cover 36 and the top of the pressing frame 38, respectively, to provide an upward reset force for the moving rod 37.

[0056] A transmission assembly is installed at the top of the moving rod 37, and the transmission assembly is connected to the suction mechanism. The transmission assembly includes two second support plates 41 symmetrically fixedly installed on the top of the fixed cover 36, and the two second support plates 41 are rotatably connected to the same U-shaped rod 43 on one side close to each other. A rectangular ring 42 is fixedly installed at the top of the moving rod 37, and the U-shaped rod 43 penetrates the rectangular ring 42 and cooperates with the rectangular ring 42. When the U-shaped rod 43 rotates, it will drive the rectangular ring 42 and the moving rod 37 to move together.

[0057] A U-shaped frame 46 is rotatably sleeved on the U-shaped rod 43, and an L-shaped plate 44 is slidably connected to the top of the fixed cover 36. Two limit rods 45 are symmetrically fixedly installed on the L-shaped plate 44, and two limit plates 47 are symmetrically fixedly installed in the U-shaped frame 46. The limit rods 45 penetrate the corresponding limit plates 47 and are slidably connected to the limit plates 47. This structure enables the L-shaped plate 44 to drive the U-shaped frame 46 to move horizontally when moving, thereby generating a pulling force on the U-shaped rod 43 to rotate it.

[0058] The L-shaped plate 44 is connected to the air suction mechanism, and two reset rods 49 are symmetrically fixedly installed on one side of the L-shaped plate 44. A mounting plate 48 is slidably sleeved on the reset rod 49, and the mounting plate 48 is fixedly installed on the top of the fixed cover 36. A reset spring 50 is sleeved on the reset rod 49, and the two ends of the reset spring 50 are respectively fixedly connected to one side of the mounting plate 48 and one end of the reset rod 49, so as to provide elastic force for the L-shaped plate 44 to reset.

[0059] The suction mechanism includes a vacuum pump 55 fixedly mounted on one side of the top of the processing box 2, and a connecting pipe 56 is fixedly mounted on the suction end of the vacuum pump 55, one end of the connecting pipe 56 extends into the fixed cover 36 and is fixedly connected to the inner wall of one side of the fixed cover 36. A first solenoid valve 57 is fixedly mounted in the connecting pipe 56 for controlling the on-off of the connecting pipe 56. An air supply pipe 54 is fixedly mounted on the inner wall of the top of the connecting pipe 56, and the top end of the air supply pipe 54 extends to the top of the fixed cover 36 and is fixedly mounted with a transmission box 51. A second piston plate 53 is sealingly and slidably connected to the inner wall of the transmission box 51, and a transmission rod 52 is fixedly mounted on one side of the second piston plate 53, and one end of the transmission rod 52 extends to the outside of the transmission box 51 and is fixedly connected to one side of the L-shaped plate 44. A second solenoid valve 58 is fixedly mounted in the air supply pipe 54 for controlling the on-off of the air supply pipe 54.

[0060] When the vacuum pump 55 is started, it will extract the gas in the processing box 2 and the fixed cover 36, so that the processing box 2 is in a vacuum state. In this process, the gas in the transmission box 51 will be transported to the connecting pipe 56 through the air pipe 54, and then discharged through the vacuum pump 55. This causes the transmission box 51 to be in a negative pressure state, thereby driving the second piston plate 53 to move. The movement of the second piston plate 53 will drive the L-shaped plate 44 to move laterally through the transmission rod 52. During the movement of the L-shaped plate 44, it will drive the U-shaped frame 46 to move through the sliding cooperation of the limit rod 45 and the limit plate 47, thereby generating a pulling force on the U-shaped rod 43 to rotate downward. The rotation of the U-shaped rod 43 will drive the moving rod 37 to move downward through the rectangular ring 42. The downward movement of the moving rod 37 will drive the pressing frame 38 and the pressing rod 39 to move together, thereby pressing the upper panel 22 and the sound insulation frame 21.

[0061] After the pressing is completed, when the vacuum pump 55 stops working, the first solenoid valve 57 and the second solenoid valve 58 will be closed, and the L-shaped plate 44 will move in the reverse direction under the elastic force of the return spring 50. The return movement of the L-shaped plate 44 will drive the moving rod 37 and the pressing frame 38 to move upward through the transmission assembly, thereby completing a pressing cycle.

[0062] Two support columns 4 are symmetrically fixedly installed on one side of the door panel 3. Wheels 5 are installed at the bottom ends of the two support columns 4 by means of rotational connection, so that when the door panel 3 needs to be moved, it can rely on the two wheels 5 for rolling support, thereby realizing the lateral movement of the door panel 3. In order to maintain the stability and linearity of the door panel 3 during movement, a mounting rod 6 is also fixedly installed on the side where the two support columns 4 are close to each other. A connecting rod 7 is fixedly connected to one side of the mounting rod 6, and a sliding rod 9 is fixedly installed at the end of the connecting rod 7. Both ends of the sliding rod 9 are designed with sliding connection structures, which can slide with the sliding rails 8 fixed on the multiple columns 1. Therefore, when the door panel 3 is pulled to move, the sliding rod 9 will keep moving in a straight line under the guidance of the sliding rails 8, thereby ensuring that the door panel 3 can be stably and accurately clamped with the processing box 2.

[0063] Example 2: Reference Figure 4 This embodiment is based on the first embodiment. Regarding the production process proposed in the first embodiment, in order to further enhance the connection stability and convenience between the door panel 3 and the processing box 2, a rotating rod 10 is rotatably connected to the top of one side of the door panel 3. Two clamping plates 11 are symmetrically fixedly mounted on the rotating rod 10. A clamping shaft 12 is fixedly installed on the top of both sides of the processing box 2. When the door panel 3 is moved to the opening of the processing box 2 and is ready to be engaged, the rotating rod 10 can be rotated so that the two clamping plates 11 are respectively engaged with the corresponding clamping shafts 12. This clamping method can effectively fix the door panel 3 to prevent it from accidentally opening or moving during the processing process.

[0064] In order to limit the rotation rod 10 and ensure that it can be stably maintained in the clamping state, a clamping ring 13 is also slidably sleeved on the rotation rod 10. A positioning frame 14 is fixedly installed on the top of one side of the door panel 3, and this positioning frame 14 can be movably clamped with the clamping ring 13. At the same time, a first compression spring 15 is also sleeved on the rotation rod 10, and the two ends of this spring are respectively fixedly connected to one side of the door panel 3 and one side of the clamping ring 13. Therefore, after the door panel 3 is clamped with the processing box 2, and the rotation rod 10 is rotated to complete the clamping of the clamping plate 11 and the clamping shaft 12, the clamping ring 13 can be released. At this time, the first compression spring 15 in a stressed state will push the clamping ring 13 to move until the clamping ring 13 is clamped with the positioning frame 14. In this way, the clamping ring 13 will limit the rotation rod 10 to prevent it from accidentally rotating or loosening, thereby ensuring that the clamping plate 11 can be tightly clamped with the corresponding clamping shaft 12.

[0065] Instructions for use: First, stack the lower panel 20 and the sound insulation frame 21 in the pressing box 19, and then apply the upper panel 22 to the four rubber skirts 27. At this time, the pull rods 32 can be pulled at the same time to make the corresponding two pull rods 32 close to each other. When the pull rods 32 move, the first piston plate 31 can be driven to move, so that the gas in the suction cover 26 can be sucked into the suction cover 29, so that the suction cover 26 is in a negative pressure state. After that, the threaded disk 33 and the threaded cover 34 can be threadedly connected, so that the two suction covers 26 can maintain a constant suction force and stably brake the upper panel 22. Then, the door panel 3 can be pushed to make the door panel 3 block the processing box 2. Then, the rotating rod 10 can be rotated to make the two clamping plates 11 They are respectively clamped with the corresponding clamping shafts 12, so that the door panel 3 can be stably clamped, and then the clamping ring 13 can be released, and the first compression spring 15 in a stressed state can push the clamping ring 13 to move, so that the clamping ring 13 and the positioning frame 14 are clamped, so that the rotating rod 10 can be limited and braked, so that the clamping plate 11 and the corresponding clamping shaft 12 are tightly clamped, and the vacuum pump 55 can be started to extract the gas in the processing box 2 and the fixed cover 36, so that the processing box 2 is in a vacuum state, and in the process of exhausting air, the gas in the transmission box 51 can be transported to the connecting pipe 56 through the air supply pipe 54, and then it can be discharged through the vacuum pump 55, so that the transmission box 51 is in a negative pressure state, which can drive the second piston plate 53 to advance. The U-shaped frame 46 can be moved laterally by the transmission rod 52, and the U-shaped frame 46 can be moved laterally by the sliding cooperation of the two limit rods 45 and the corresponding limit plates 47. At this time, a pulling force can be provided to the U-shaped rod 43, so that the U-shaped rod 43 rotates downward, so that the moving rod 37 can be driven to move downward under the transmission cooperation with the rectangular ring 42. When the moving rod 37 moves downward, it can drive the pressing frame 38 to move downward. At this time, the four pressing rods 39 can press the four pressing head rods 25 to move downward respectively, so that the upper panel 22 and the sound insulation frame 21 can be pressed conveniently. Since the four pressing head rods 25 are pressed synchronously by the four pressing rods 39, the upper panel 22 When being pressed together with the sound insulation frame 21, the upper panel 22 can be evenly stressed, so that the upper panel 22 and the sound insulation frame 21 can be tightly bonded, and when the vacuum pump 55 is started, the upper panel 22 and the sound insulation frame 21 can be pressed while evacuating the processing box 2, so that there is no gap between the lower panel 20 and the upper panel 22, and when the L-shaped plate 44 moves, it can drive the reset rod 49 to move, so that the reset spring 50 is in a stressed state. Therefore, when the L-shaped plate 44 is not subjected to the driving force of the suction mechanism, the elastic force of the two reset springs 50 can make the L-shaped plate 44 move in the opposite direction, thereby driving the pressing frame 38 to move upward.
