Description

Technical Field

[0001] The utility model relates to the technical field of plate processing equipment, in particular to a plate flat laminating machine. Background Art

[0002] In the advertising industry and building materials decoration industry, in order to improve the appearance or use experience of the board, the board is usually coated with film. The initial coating method is generally to first apply glue, spray glue or pour glue on the board, and then cure it with a UV lamp. Since the glue itself has a strong odor, it evaporates more during curing, and there are many overflowing glue stains, which pollute the working environment. As an improvement, the current better coating method is to use a flat laminating machine to complete the film on the board. The film laminating method of the flat laminating machine is generally to pass the viscose film and the board through the upper and lower rollers, and the board and the film are bonded together by the rollers.

[0003] An existing plate laminating machine (publication number: CN220314443U) has at least the following drawbacks: the above-mentioned device preheats the film and the plate by arranging a first heating hood and a second heating hood inside the machine body, and then heats them during the pressing process to keep the surface temperature of the film and the plate uniform. However, after the pressing is completed, the temperature of the film and the plate is still relatively high just after being heated and pressed. If the external environment is relatively cold, the temperature of the film and the plate will drop rapidly, making the colloid curing speed between the film and the plate uneven, and the problem of warping may still occur. For this reason, the present utility model is proposed. Utility Model Content

[0023] In this embodiment, detection holes 203 are provided at the center of the top surface and near the front side of the cooling chamber 2, and a temperature sensor 204 is fixed inside the detection hole 203. A first hydraulic rod 205 is fixed on the top surface of the cooling chamber 2, and one end of the telescopic rod of the first hydraulic rod 205 penetrates the top surface of the cooling chamber 2 and is fixed to the top surface of the upper heating plate 202. A preheating box 206 is inserted through the top surface of the body 1, and the preheating box 206 extends to one end of the body 1 as an air outlet, and the other end is opened as an air inlet. A first motor is fixed on one side of the preheating box 206, and the output shaft of the first motor penetrates one side of the preheating box 206 and extends to the interior of the preheating box 206. A cross-flow fan blade 207 is fixed to the output shaft end of the first motor, and a heating pipe 208 is fixed inside the preheating box 206 and in front of the cross-flow fan blade 207. By setting the preheating box 206 and in the preheating Cross-flow fan blades 207 and heating tubes 208 are respectively arranged inside the box 206, so that the preheating box 206 can continuously input hot air into the body 1, so that the plate and the film are preheated by the hot air before being pressed. When the hot air is blown to the plate and the film, it flows along the front and rear sides of the plate surface, so that the surface of the plate is evenly preheated, so that the film is better fitted to the plate. By setting a cooling chamber 2, the plate and the film are input to the interior of the cooling chamber 2 after being pressed, and the lower heating plate 201 and the upper heating plate 202 are fitted with the top and bottom surfaces of the plate, and the surface temperature of the plate is detected by the temperature sensor 204, and then the heating temperature of the lower heating plate 201 and the upper heating plate 202 is gradually reduced, so that the surface temperature of the plate is uniform and decreases slowly, effectively avoiding the problem of uneven gluing speed of the film when the external environment is cold, which causes the film to warp.

[0024] In this embodiment, an air filter 209 is fixed inside the preheating box 206 near the air inlet, and the air entering the preheating box 206 can be filtered through the air filter 209 to reduce dust contamination on the plate and the film, thereby increasing the bonding effect between the film and the plate.

[0025] In this embodiment, a support plate 3 is fixed to the top surface of the body 1, and a second hydraulic rod 301 is fixed to the bottom surface of the support plate 3. The telescopic rod of the second hydraulic rod 301 is fixed to the top surface of the connecting frame 103. Sliding holes 302 are opened on the left and right sides of the body 1. The bottom end of the connecting frame 103 passes through the top surface of the body 1 and is slidably arranged inside the sliding hole 302. By setting the second hydraulic rod 301, the upper hot pressing roller 104 can be driven to move up and down, so that the distance between the upper hot pressing roller 104 and the lower hot pressing roller 102 can be adjusted according to the thickness of the plate to be leveled, thereby increasing the applicability of the device.

[0026] The second motor is fixed to the left side of the machine body 1, and the output shaft of the second motor is fixed to the left end of the lower hot pressing roller 102 near the middle of the machine body 1. The internal rotation of the connecting frame 103 is provided with a rubber-coated roller 5. The top surface of the machine body 1 is fixed with a rotating frame 501, and the internal rotation of the rotating frame 501 is connected with a film winding roller 502. The outer wall of the film winding roller 502 is wound with a coating film, and one end of the coating film is clamped between the coating roller 5 and the lower hot pressing roller 102, and the bonding surface of the coating film is bonded to the outer wall of the coating roller 5. The gears of the two lower hot pressing rollers 102 are meshed with a toothed belt for transmission. When the second motor drives one of the lower hot pressing rollers 102 to rotate, the two lower hot pressing rollers 102 rotate synchronously to prevent the two lower hot pressing rollers 102 from rotating at different speeds, which causes friction between the lower hot pressing roller 102 and the plate to affect the flattening effect.

[0027] In this embodiment, two limit rods 4 are fixed on the top surface of the upper heating plate 202, and the limit rods 4 penetrate the bottom surface of the body 1 and are slidably inserted.

[0028] The limiting rod 4 can limit and support the upper heating plate 202, so that the upper heating plate 202 and the lower heating plate 201 remain parallel, and the upper heating plate 202 and the lower heating plate 201 better fit the top and bottom surfaces of the plates.

[0029] From the above description, it can be seen that the above-mentioned embodiment of the utility model achieves the following technical effects: in use, according to the thickness of the plate to be flattened, the second hydraulic rod 301 is connected to the frame 103 and moves up and down respectively, so as to adjust the distance between the upper hot pressing roller 104 and the lower hot pressing roller 102, and then the plate to be flattened is placed in from the feed port of the body 1 on the front side of the body 1, and the support roller 101 supports the plate. In this process, the first motor is started to drive the cross-flow fan blade 207 to rotate, and the heating tube 208 is started. At this time, the preheating box 206 can continuously input hot air into the body 1. When the hot air is blown to the plate and the coating, it flows along the front and rear sides of the plate surface, so that the surface of the plate is preheated. The coating is better fitted to the plate, and then the plate is clamped by the upper hot pressing roller 104 and the lower hot pressing roller 102 and begins to be transported from the front side of the machine body 1 to the rear side of the machine body 1. During this process, the upper hot pressing roller 104 cooperates with the rubber-coated roller 5 to transport the coating to the plate, and the rubber-coated roller 5 adds colloid to the bonding surface of the coating, and then the preheated plate and the coating are pressed by the upper hot pressing roller 104 and the lower hot pressing roller 102. After the pressing is completed, the plate is transported to the inside of the preheating box 206, and the plate is located on the top surface of the lower heating plate 201. The first hydraulic rod 205 is started to drive the upper heating plate 202 to approach the lower heating plate 201 and clamp the plate. At this time, the lower heating plate 201 and the upper heating plate 2 02 is fitted with the top and bottom surfaces of the plate, and the temperature sensor 204 detects the temperature at the center and edge of the plate respectively. The staff adjusts the heating temperature of the lower heating plate 201 and the upper heating plate 202 according to the plate surface detected by the temperature sensor 204, so that the surface temperature of the plate slowly decreases, effectively avoiding the problem of warping caused by cold shrinkage of the film when the external environment is cold. The air entering the preheating box 206 can be filtered through the air filter 209 to reduce dust contamination on the plate and the film, and increase the fitting effect of the film and the plate. The second hydraulic rod 301 can be set to drive the upper hot pressing roller 104 to move up and down. Therefore, the distance between the upper hot pressing roller 104 and the lower hot pressing roller 102 can be adjusted according to the thickness of the plate to be flattened, thereby increasing the applicability of the device. The gears of the two lower hot pressing rollers 102 are driven by toothed belt meshing. When the second motor drives one of the lower hot pressing rollers 102 to rotate, the two lower hot pressing rollers 102 rotate synchronously to prevent the two lower hot pressing rollers 102 from rotating at different speeds, which would cause friction between the lower hot pressing rollers 102 and the plate and affect the flattening effect. By setting a limit rod 4, the upper heating plate 202 can be limited and supported, so that the upper heating plate 202 and the lower heating plate 201 remain parallel, so that the upper heating plate 202 and the lower heating plate 201 can better fit the top and bottom surfaces of the plate.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
