Description

Technical Field

[0001] This utility model relates to the field of PET film-faced artificial board production technology, specifically a low-temperature hot pressing device for sheet PET film-faced artificial boards. Background Technology

[0002] In industries such as furniture manufacturing and interior decoration, sheet PET film-faced engineered wood panels have been widely used due to their attractive appearance, good wear resistance, and stain resistance. Hot-pressing is a crucial step in bonding PET film to engineered wood panels. PET film possesses unique optical properties, and its surface gloss is one of the important indicators for evaluating the quality of sheet PET film-faced engineered wood panels. To avoid a decrease in gloss due to high-temperature hot pressing, low-temperature hot-pressing equipment is used for processing.

[0003] Based on the above, the inventors have discovered the following problem: During the sheet hot pressing process, the hot press plate needs to apply downward pressure to ensure a tight bond between the sheet and the finishing material. In existing low-temperature hot pressing devices, the hot press plate is directly and rapidly pressed down into contact with the sheet under the action of the driving mechanism. Because the PET film in the sheet, especially in PET film-finished engineered wood panels, is relatively soft, and the engineered wood panels themselves have uneven density, the rigid pressure applied instantaneously by the hot press plate can cause excessive localized stress on the sheet surface, leading to surface damage.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a low-temperature hot pressing device for sheet PET film-faced artificial boards, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a low-temperature hot pressing device for sheet PET film-faced artificial boards, in order to solve the problem mentioned in the background art that the hot pressing plate of the existing low-temperature hot pressing device directly and quickly presses down and contacts the sheet under the action of the driving mechanism, which causes the sheet surface to bear excessive local stress.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A low-temperature hot-pressing device for sheet PET film-faced artificial boards includes a driving mechanism, a buffer mechanism, and a forming mechanism. The driving mechanism includes a base, with slide rods fixedly installed at the four corners of the upper end of the base, and a top plate fixedly installed at the top of the four slide rods. The buffer mechanism includes a movable plate located at the bottom of the top plate, with its four corners slidably connected to the slide rods. A pair of limiting rods are slidably inserted on both sides of the upper surface of the movable plate, and springs are sleeved at the bottom of each limiting rod.

[0014] Furthermore, a power connector is fixedly installed on one side of each of the hot press plates, and the power connector is electrically connected to the corresponding heating wire via a wire.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the power connector is electrically connected to the heating wire through a wire, which facilitates the connection to an external power source to supply power to the heating wire and realize the heating function of the hot press plate.

[0016] Furthermore, a pair of T-shaped sliding grooves are provided at the bottom end of the movable plate and the top end of the base plate.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-4A pair of telescopic rods 104 are inserted into the upper end of the top plate 103. Each telescopic rod 104 has a pressure sensor 105 mounted on its bottom end. The bottom end of the pressure sensor 105 is connected to the top end of the moving plate 201. The telescopic rods 104 on the top plate 103 can drive the moving plate 201 to move up and down, thereby applying pressure to the plate. The pressure sensor 105 monitors the pressure applied to the moving plate 201 in real time and feeds the data back to the operator, which facilitates precise control of the hot pressing pressure, avoids insufficient or excessive pressure affecting the forming quality of the plate, and ensures that the pressure during the hot pressing process meets the process requirements.

[0032] Specifically, the working principle of this low-temperature hot pressing device for sheet PET film-faced artificial boards is as follows: During use, the telescopic rod 104 on the top plate 103 is activated, driving the moving plate 201 downwards along the sliding rod 102. At this time, the moving plate 201 pushes the movable plate 301 downwards via the limiting rod 202. The hot pressing plate 304 at the bottom of the movable plate 301 gradually approaches the board material along with the hot pressing plate 304 on the bottom plate 302. During this process, the pressure sensor 105 monitors the pressure applied to the moving plate 201 in real time and feeds the data back to the operator for precise pressure control. When the hot pressing plate 304 contacts the board material, the power connector 305 connects to an external power source, supplying power to the coiled heating wires 307 inside the hot pressing plate 304, causing them to heat up evenly and providing heat for hot pressing. Temperature sensor 308 monitors the temperature inside hot press plate 304 in real time. Operators adjust the heating temperature in a timely manner based on the monitoring data to ensure accurate hot pressing temperature. At the same time, spring 203 is compressed under pressure to generate buffer force, absorb pressure fluctuations, and ensure uniform and stable pressure during the hot pressing process, preventing deformation and damage to the sheet material due to sudden pressure changes. After hot pressing is completed, telescopic rod 104 drives moving plate 201 to move upward and reset. Movable plate 301 also resets under the action of spring 203. If it is necessary to replace hot press plate 304, the sliding cooperation between T-shaped slide rod 306 and T-shaped slide groove 303 can be used to easily disassemble and install hot press plate 304. The whole process realizes low-temperature hot pressing molding of sheet PET film-faced artificial board, ensuring product quality and production efficiency.
