Description

Technical Field

[0001] The utility model relates to the technical field of decorative panel production, in particular to a hot pressing and forming device for decorative panel production. Background Technique

[0002] The full name of the decorative panel is decorative veneer faced plywood. It is a surface material for interior decoration formed by adhering natural wood to the surface of plywood and then hot pressing with a hot press. However, most of the existing hot presses do not have two sets of pressing mechanisms, resulting in poor stability. Moreover, most of the existing hot presses do not have a waste heat recovery structure. They often directly use electric heating plates to heat the plates, which not only cannot achieve waste heat recovery but also cannot be recycled. The design has defects and is not convenient to use.

[0003] As disclosed in Chinese Patent Publication No. CN216181403U, a hot press for fireproof decorative panel production with a waste heat recovery structure is provided. When in use, the fireproof decorative panel to be pressed is placed between the bottom pressing mechanism and the top pressing mechanism. At this time, the staff uses the control switch to turn on the driving motor, the bottom hydraulic press, and the hydraulic cylinder. The bottom hydraulic press can push the bottom pressing plate upward. The electrothermal oil in the heating tank 1 can heat the bottom pressing plate. The movable end of the hydraulic cylinder can push the fixed seat downward. The fixed seat can drive the top pressing plate downward. The electrothermal oil in the heating tank 2 can heat the top pressing plate. By reducing the distance between the top pressing plate and the bottom pressing plate, the device can press the plate. The driving motor can drive the screw rod to rotate. The screw rod and the threaded sleeve can reduce the distance between the bottom pressing plate and the top pressing plate, improving the pressing effect of the hot press. Through two control valves 1, the two connecting pipes 4 can be controlled separately. The oil pump box can suck the electrothermal oil into the electrothermal oil tank through the connecting pipe 3 on the left side of the base and the connecting pipe 4. The electrothermal oil tank can heat the electrothermal oil. The heated electrothermal oil can enter the heating tank 2 and the heating tank 1 through the connecting pipe 1, the connecting pipe 2, the connecting pipe 3 on the right side of the base, and the connecting pipe 5, achieving waste heat recovery and recycling at the same time. The overall design is reasonable and convenient to use.

[0004] However, the hot press for fireproof decorative panel production with a waste heat recovery structure in the above application often produces harmful gases during the hot pressing process, which need to be purified to avoid affecting the health of workers. Therefore, there are certain limitations.

[0005] Therefore, we urgently need to provide a hot pressing and forming device for decorative panel production. Content of the Utility Model

[0006] The purpose of the present utility model is to provide a hot pressing and forming device for decorative panel production, so as to solve the problem in the above-mentioned background technology that for the hot pressing of fireproof decorative panels with waste heat recovery structure, harmful gases are often generated during the hot pressing process, and it is necessary to purify them to avoid affecting the physical health of workers.

[0007] To achieve the above purpose, the present utility model provides the following technical solution: A hot pressing and forming device for decorative panel production, including a base and a hot press. The hot press is installed on the base, and purification devices are respectively arranged on both sides of the top of the hot press, and a forming device is arranged inside the hot press.

[0008] The purification device includes a water washing tank, an exhaust pipe, a water inlet pipe, a sewage discharge pipe, an electric sealing valve, and a purification component. The water washing tank is installed at the rear end of the left side of the top of the hot press. The front end of the exhaust pipe extends into the interior of the hot press, and the rear end extends into the lower part of the interior of the water washing tank. The water inlet pipe is fixedly connected to the rear end of the left side of the top of the water washing tank. The sewage discharge pipe is fixedly connected to the bottom of the right side of the back of the water washing tank. The electric sealing valve is installed on the sewage discharge pipe. The purification component is installed at the rear end of the right side of the top of the water washing tank. Harmful gases generated during the hot pressing process enter the water body of the water washing tank through the exhaust pipe, thereby washing and purifying the harmful gases. When the water body inside the water washing tank is polluted, start the electric sealing valve to discharge the sewage through the sewage discharge pipe, and then replenish water through the water inlet pipe.

[0009] Further improvement lies in that the purification component includes a discharge pipe, a placement box, and a pull ring. The discharge pipe is installed at the rear end of the right side of the top of the water washing tank. The placement box is installed inside the discharge pipe. The pull ring is fixedly connected to the center of the back of the placement box.

[0010] Further improvement lies in that a push-pull groove is opened on the back of the discharge pipe. The placement box is slidably connected inside the push-pull groove, and activated carbon is placed inside the placement box. Uniform ventilation holes are formed through the bottom of the placement box. The gas after water washing is discharged through the discharge pipe and passes through the inside of the placement box. The harmful gases and odors in the gas are adsorbed by the activated carbon placed inside. Regularly pull the pull ring to take out the placement box from the inside of the push-pull groove to replace the activated carbon inside.

[0011] Further improvement lies in that the molding device includes a hydraulic cylinder, a pressing plate, a buffer assembly, a hot pressing fixing plate, an electric heating plate, and a heat conducting pressing plate. The hydraulic cylinder is installed at the center of the top of the hot press, and its bottom extends into the interior of the hot press. The pressing plate is fixedly connected to the bottom of the hydraulic cylinder. Four groups of the buffer assemblies are respectively installed at the four corners of the bottom of the pressing plate. The hot pressing fixing plate is fixedly connected to the bottom of the buffer assembly. The electric heating plate is installed at the bottom of the hot pressing fixing plate. The heat conducting pressing plate is installed at the bottom of the electric heating plate. Place the decorative panel inside the hot press, then start the electric heating plate to heat up, and start the hydraulic cylinder to drive the pressing plate to move down, thereby driving the hot pressing fixing plate and the electric heating plate at its bottom to move down, and further enabling the heat conducting pressing plate to move down to contact the decorative panel for hot pressing.

[0012] Further improvement lies in that the buffer assembly includes a through hole, a limiting rod, and a buffer spring. The through hole is penetrated and opened on the pressing plate. The limiting rod is installed inside the through hole. The buffer spring is fixedly connected between the pressing plate and the hot pressing fixing plate and is located outside the limiting rod. When the heat conducting pressing plate moves down to contact the decorative panel, as the pressing plate continues to press down, the buffer spring is compressed, thereby using the elasticity of the buffer spring for a certain amount of buffering to avoid the situation of excessive pressing at one time and causing damage to the decorative panel.

[0013] Further improvement lies in that sliding grooves are respectively opened on the left and right sides of the top of the hot press. A flange bushing seat is installed inside the sliding groove. A guiding column is slidably connected inside the flange bushing seat, and its bottom is connected to the pressing plate. When the pressing plate moves down, it pulls the guiding column to move down along the flange bushing seat, thereby ensuring that the pressing plate moves vertically and avoiding its skew, which affects the hot pressing effect.

[0014] Further improvement lies in that sealing doors are respectively hinged on the left and right sides of the front of the hot press. A handle is installed on the front of the sealing door. An observation window is installed on the inner side of the sealing door, and an observation window is also installed on the left outer surface of the water washing tank. Closing the sealing door can isolate the gas generated during hot pressing and then process it through the purification device, avoiding workers inhaling harmful gases and causing physical damage, and can maintain the temperature inside the hot press to a certain extent and save energy. Through the observation window, the hot pressing situation of the decorative panel inside the hot press can be observed in real time.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. For the hot pressing and forming device for producing decorative panels, the harmful gases generated during the hot pressing process enter the water body of the water washing tank through the exhaust pipe, thereby washing and purifying the harmful gases.

[0017] 2. The hot pressing and forming device for producing the decorative panel discharges the gas after water washing through the discharge pipe, which passes through the inside of the placement box. The activated carbon placed inside adsorbs the residual harmful gases and odors in the gas. Periodically pull the pull ring to take out the placement box from the inside of the push-pull groove and replace the activated carbon inside it. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Please refer to Figures 1 - 5 , the present utility model provides a technical solution:

[0026] Embodiment 1:

[0027] A hot pressing and forming device for producing decorative panels, including a base 1 and a hot press 2. The hot press 2 is installed on the base 1. Purifying devices are respectively arranged on both sides of the top of the hot press 2, and a forming device is arranged inside the hot press 2.

[0028] The purifying device includes a water washing tank 301, an exhaust pipe 302, a water inlet pipe 303, a sewage discharge pipe 304, and an electric sealing valve 305. The water washing tank 301 is installed at the rear end of the left side of the top of the hot press 2. The front end of the exhaust pipe 302 extends into the interior of the hot press 2, and the rear end extends into the lower part of the interior of the water washing tank 301. The water inlet pipe 303 is fixedly connected to the rear end of the left side of the top of the water washing tank 301. The sewage discharge pipe 304 is fixedly connected to the bottom of the right side of the back of the water washing tank 301. The electric sealing valve 305 is installed on the sewage discharge pipe 304. Harmful gases generated during the hot pressing process enter the water body of the water washing tank 301 through the exhaust pipe 302, thereby washing and purifying the harmful gases. When the water body inside the water washing tank 301 is polluted, the electric sealing valve 305 is started to discharge the sewage through the sewage discharge pipe 304, and then water is replenished through the water inlet pipe 303.

[0029] The forming device includes a hydraulic cylinder 401, a pressing plate 402, a buffer assembly 403, a hot pressing fixed plate 404, an electric heating plate 405, and a heat conducting pressing plate 406. The hydraulic cylinder 401 is installed at the center of the top of the hot press 2, and its bottom extends into the interior of the hot press 2. The pressing plate 402 is fixedly connected to the bottom of the hydraulic cylinder 401.
