Detailed Implementation

[0017] This application discloses an adaptive furniture board coating hot press roller. Hot air is blown from the bottom of the hot press roller body 20 by the hot air blower 72, so that the adhesive is less likely to become uneven due to cooling, thereby improving the coating effect and reducing adhesive residue. The spring 64 drives the scraper 62 to contact the outside of the hot press roller body 20 to scrape off the residual adhesive and drop it into the collection bin 65, preventing the residual adhesive from affecting the coating.

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] Please refer to Figure 1 and Figure 2 This embodiment provides an adaptive furniture board coating hot press roller, including a hot press roller body 20 rotatably connected to the bottom of a mounting base 10. A connecting seat 30 is provided on the top of the mounting base 10, and the top of the connecting seat 30 is connected to a hydraulic rod. A cleaning assembly 60 is provided on the front of the mounting base 10, and a blowing assembly 70 is provided on the back of the mounting base 10. The blowing assembly 70 includes a connecting plate 71 and a hot air blower 72. The connecting plate 71 is fixedly disposed on the back of the mounting base 10, and the hot air blower 72 is installed at the bottom of the connecting plate 71. The bottom of the blower 72 faces the bottom of the hot press roller body 20. The hydraulic rod drives the connecting seat 30 and the mounting seat 10 to move down, so that the hot press roller body 20 at the bottom of the mounting seat 10 moves down onto the board and applies pressure to the board to perform the film coating work. When the outside temperature is low, hot air is blown out by the hot air blower 72 towards the bottom of the hot press roller body 20, so that when the hot press roller body 20 coats the board, the curing of the adhesive can be more uniform, preventing edge curling and reducing adhesive residue on the hot press roller body 20.

[0020] Please refer to Figure 1 , Figure 2 and Figure 3The cleaning component 60 includes a fixed base 61, a scraper 62, guide rails 63, a spring 64, a collection bin 65, a baffle 66, and a locking block 67. The fixed base 61 is slidably connected to the front of the mounting base 10. A movable groove 611 is provided on the side of the fixed base 61 near the hot press roller body 20. The scraper 62 is slidably connected inside the movable groove 611. Multiple guide rails 63 are fixedly installed inside the movable groove 611, and the multiple guide rails 63 are interlocked with the scraper 62. The spring 64 is sleeved... Located on the outside of the guide rail 63, and with the spring 64 positioned between the inner wall of the movable groove 611 and the scraper 62, the collection chamber 65 is detachably mounted on the bottom of the fixed base 61 and the scraper 62, with the bottom inner wall of the collection chamber 65 inclined upwards towards the hot press roller body 20. Two baffles 66 are respectively mounted on both sides of the collection chamber 65, and two locking blocks 67 are symmetrically mounted on the front of the collection chamber 65. The front of the fixed base 61 has two locking slots 612, and the locking blocks 67 engage with the locking slots. 612 is snapped in place. Two electric push rods 68 are respectively set on both sides of the front of the mounting base 10. One end of the two electric push rods 68 is fixedly connected to the fixed base 61. The extension and retraction of the electric push rods 68 drives the fixed base 61 to move closer to the hot press roller body 20. With the elastic force of the spring 64, the scraper 62 can be tightly attached to the outside of the hot press roller body 20. After the film is coated, the scraper 62 can scrape off the residual adhesive on the hot press roller body 20 when the hot press roller body 20 rotates. The scraped residual adhesive falls into the collection chamber 65 at the bottom. Because the bottom inner wall of the collection chamber 65 is inclined, the adhesive slides into the interior of the collection chamber 65. Two baffles 66 are set on both sides of the collection chamber 65 to seal both sides of the collection chamber 65 to prevent impurities from falling from both sides onto the bottom plate or conveyor roller. The collection chamber 65 can be removed by opening the two locking blocks 67 on one side of the collection chamber 65 to centrally process the adhesive and prevent the adhesive residue on the hot press roller body 20 from affecting the film coating effect.

[0021] Please refer to Figures 1-3 A pressure sensor 40 is provided on the top of the connecting seat 30, and a display 50 is provided on the side of the mounting seat 10. The pressure sensor 40 and the display 50 are electrically connected. The connecting seat 30 is installed at the bottom of the hydraulic rod. The pressure sensor 40 can measure the pressure received by the hydraulic rod when it is pressed down, thereby detecting the pressure of the hot press roller body 20 on the bottom plate. The display 50 displays the pressure value. When the pressure of the bottom plate exceeds the threshold, the hydraulic rod stops driving the hot press roller body 20 to move down, so that the hot press roller body 20 can adapt to plates of different thicknesses, which is convenient for coating different plates.

[0022] The functional principle of this application can be explained through the following methods:

[0023] In use, the connecting seat 30 is installed at the bottom of the hydraulic rod. The hydraulic rod drives the mounting seat 10 and the hot press roller body 20 to move down to the top of the board. The pressure sensor 40 detects the pressure on the hydraulic rod, thereby detecting the pressure of the hot press roller body 20 on the board. The display 50 shows the pressure value. When the pressure on the bottom board exceeds the threshold, the hydraulic rod stops driving the hot press roller body 20 to move down, allowing the hot press roller body 20 to adapt to boards of different thicknesses, facilitating lamination work on different boards. When laminating, if the external temperature is low, the hot air blower 72 is started. As the hot press roller body 20 rotates, the hot air blower 72 towards the bottom of the hot press roller body 20, preventing the adhesive from suddenly cooling during lamination. This allows the adhesive to cure more evenly on the board and reduces the adhesive residue. After the film coating is completed, the electric push rod 68 is activated, which moves the fixed seat 61 towards the hot press roller body 20. The scraper 62 first contacts the hot press roller body 20, and then continues to approach a certain distance. The spring 64 inside the movable groove 611 is in a compressed state. The elasticity of the spring 64 makes the scraper 62 stick tightly to the outside of the hot press roller body 20. When the hot press roller body 20 rotates, the scraper 62 can scrape off the adhesive residue on the outside of the hot press roller body 20. The adhesive falls into the collection chamber 65, which is inclined at the bottom. The baffles 66 on both sides prevent the adhesive inside the collection chamber 65 from falling into the plate or conveyor roller from both sides. Opening the latches 67 on both sides of the collection chamber 65 allows the collection chamber 65 to be removed from the bottom of the fixed seat 61, and the adhesive inside the collection chamber 65 can be cleaned in a concentrated manner.
