Description

Technical Field

[0001] This utility model relates to the field of coated plywood production, specifically to a coating equipment for coated plywood production. Background Technology

[0002] In the plywood production process, laminating equipment is required to coat the plywood surface. However, most existing laminating equipment for plywood production can only coat one side of the plywood. Therefore, double-sided lamination requires two coats. Furthermore, after lamination, the plywood needs to be moved to a cutting area to trim excess film around the edges, reducing the efficiency of the lamination process. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a laminating equipment for the production of laminated plywood. This solves the technical problems that most current laminating equipment for the production of laminated plywood can only laminate one side of the plywood. Therefore, when laminating both sides of the plywood, it is necessary to laminate the plywood twice. Furthermore, after lamination is completed, the laminated plywood needs to be moved to the cutting area to cut off the excess film around the plywood.

[0004] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a laminating equipment for producing laminated plywood is designed, including a processing table. Support rods are installed at the four corners of the surface of the processing table. A support plate is installed between the tops of the four support rods. A first hydraulic cylinder is installed at the bottom center of the support plate. A connecting plate is installed at the drive end of the first hydraulic cylinder. Frames are installed on both sides of the processing table and the bottom sides of the connecting plate. Unwinding rollers are installed on two frames on one side, and winding rollers are installed on two frames on the other side. A thin film is provided between the unwinding rollers and the winding rollers. A cutting mechanism is provided at the bottom center of the support plate.

[0005] Preferably, the cutting mechanism includes a second hydraulic cylinder installed at the middle of the bottom end of the support plate, the drive end of the second hydraulic cylinder is connected to a rectangular pressure cover, and a rectangular cutting blade is installed at the bottom end of the rectangular pressure cover.

[0006] Preferably, an installation rod is installed between each pair of adjacent support rods among the four support rods, and a cylinder is installed on the outer middle of each of the four installation rods. The drive end of each of the four cylinders is connected to a limit rod, and the four limit rods are all positioned above the processing table.

[0007] Preferably, a spring is installed at the top center of the inner cavity of the rectangular pressure cover, and a pressure plate is connected to the bottom of the spring, with the pressure plate slidably connected inside the rectangular pressure cover.

[0008] Preferably, rectangular holes are provided in the center of each of the four sides of the rectangular pressure cover, and all four rectangular holes are connected to the inner cavity of the rectangular pressure cover.

[0009] Preferably, a connecting frame is installed at both ends of the processing table, and a support roller is rotatably connected between the inner sides of the two connecting frames, and the top of the support roller is on the same horizontal plane as the surface of the processing table.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model combines a first hydraulic cylinder, a second hydraulic cylinder, a rectangular pressure cover, a rectangular cutting blade, an unwinding roller, and a winding roller to place the plywood to be coated between two thin films and support it on a processing table. Then, the first hydraulic cylinder is activated to move the upper film towards the surface of the plywood and adhere it, thus enabling simultaneous coating of both sides of the plywood. After the plywood is coated, the second hydraulic cylinder is activated to push the rectangular pressure cover downwards and cover the outside of the plywood. This allows the rectangular cutting blade to simultaneously cut the excess film around the perimeter of the coated plywood, detaching the plywood from the film. This eliminates the need to move the coated plywood to the cutting process to cut the excess film around the perimeter, further improving the efficiency of plywood coating.

[0012] 2. This utility model combines a cylinder and limiting rods. When laminating plywood, the cylinder is activated to push four limiting rods to form a rectangular frame. The inner dimensions of the rectangular frame match the inner dimensions of the rectangular pressure cover, allowing personnel to quickly place the plywood onto the processing table between the two films, aligning it with the rectangular pressure cover. This eliminates the need for personnel to adjust the position of the plywood to match the rectangular pressure cover, further improving the efficiency of plywood lamination. When cutting excess film around the plywood, the cylinder is first activated to pull the limiting rods away from the plywood, preventing the limiting rods from obstructing the rectangular cutting blade from cutting the film below the plywood.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0019] Example 1: A laminating equipment for producing laminated plywood, see [link to example]. Figures 1 to 4 The system includes a processing table 1, with support rods 11 installed at each of the four corners of the surface of the processing table 1. A support plate 12 is installed between the tops of the four support rods 11. A first hydraulic cylinder 2 is installed at the bottom center of the support plate 12. A connecting plate 21 is installed at the drive end of the first hydraulic cylinder 2. Frames 3 are installed on both sides of the processing table 1 and the bottom sides of the connecting plate 21. Unwinding rollers 31 are installed on two frames 3 on one side, and winding rollers 32 are installed on two frames 3 on the other side. A film 33 is placed between the unwinding rollers 31 and the winding rollers 32. Both the unwinding rollers 31 and the winding rollers 32 are driven to rotate by a motor. A cutting mechanism is installed at the bottom center of the support plate 12. The cutting mechanism includes a second hydraulic cylinder 4 installed at the bottom center of the support plate 12. A rectangular pressure cover 41 is connected to the drive end of the second hydraulic cylinder 4. A rectangular cutting blade 42 is installed at the bottom end of the rectangular pressure cover 41. During operation, the unwinding rollers 31 and the winding rollers 32 are driven by a motor to tighten the film 33 and lower the film 33. The plywood to be laminated is placed on the processing table 1, and then the plywood to be laminated is placed between the upper and lower films 33 and supported on the processing table 1. Then, the first hydraulic cylinder 2 is activated to move the upper film 33 to the surface of the plywood and laminate it, so that both sides of the plywood can be laminated at the same time. After the plywood is laminated, the second hydraulic cylinder 4 is activated to push the rectangular pressure cover 41 downward and cover the outside of the plywood. Since the width of the film 33 is greater than the width of the plywood, the rectangular cutting blade 42 can cut the excess film 33 around the laminated plywood at the same time, so that the plywood is separated from the film 33. Therefore, it is not necessary to move the laminated plywood to the cutting process to cut the excess film 33 around the plywood, which further improves the efficiency of plywood lamination. Then, the motor is activated at the same time to drive the unwinding roller 31 and the winding roller 32 to rotate so that the intact film 33 on the unwinding roller 31 is placed directly under the rectangular pressure cover 41, which facilitates the lamination of the next plywood.

[0020] For details, see Figure 2An installation rod 6 is installed between each pair of adjacent support rods 11. A cylinder 61 is installed on the outer middle of each of the four installation rods 6. The drive end of each of the four cylinders 61 is connected to a limit rod 62, and the four limit rods 62 are all positioned above the processing table 1. When the plywood is being laminated, the cylinders 61 are activated to push the four limit rods 62 to form a rectangular frame. The inner dimensions of the rectangular frame are matched with the inner dimensions of the rectangular pressure cover 41, which makes it easier for personnel to quickly place the plywood onto the processing table 1 between the two films 33 and align it with the rectangular pressure cover 41. This eliminates the need for personnel to adjust the position of the plywood to match the rectangular pressure cover 41, further improving the efficiency of plywood lamination. When cutting the excess film 33 around the plywood, the cylinders 61 are activated first to pull the limit rods 62 away from the plywood, preventing the limit rods 62 from blocking the rectangular cutting blade 42 from cutting the film 33 below the plywood.

[0021] Further, see Figure 4 A spring 45 is installed at the top center of the inner cavity of the rectangular pressure cover 41. A pressure plate 44 is connected to the bottom of the spring 45 and is slidably connected inside the rectangular pressure cover 41. When the rectangular pressure cover 41 is fitted on the outside of the plywood, the plywood pushes the pressure plate 44 to move upward and compress the spring 45. Thus, the spring 45 pushes the pressure plate 44 to squeeze the plywood after film coating, so that the film 33 is pressed tightly on the plywood, thereby improving the effect of plywood coating.

[0022] It is worth noting that, see Figure 3 The rectangular cover 41 has rectangular holes 43 in the middle of its four sides, and the four rectangular holes 43 are connected to the inner cavity of the rectangular cover 41. The rectangular holes 43 ensure that the pressure inside and outside the rectangular cover 41 is the same, so as to prevent the plywood from being adsorbed inside the rectangular cover 41 when the rectangular cover 41 is placed on the outside of the plywood, which would affect the film coating of the next plywood.

[0023] It is worth noting that, see Figure 2 Both ends of the processing table 1 are equipped with connecting frames 5. Support rollers 51 are rotatably connected between the inner sides of the two connecting frames 5. The top of the support rollers 51 is on the same horizontal plane as the surface of the processing table 1. The film 33 is supported by the support rollers 51 during the lamination process, ensuring that the film 33 can adhere to the processing table 1 and improving the quality of plywood lamination.
