Description

Technical Field

[0001] The invention relates to the technical field of hot pressing equipment for decorative panels, and more specifically to hot pressing equipment for decorative panels based on wood grain paper veneer. Background Art

[0002] The main body of the hot press can be divided into three parts: the heating system (providing heat source), the hydraulic system (providing pressure and controlling the action of the press) and the press body (frame, control part). The working principle of the hot press is to perform positive pressure on the basis of negative pressure, and use special glue to process the decorative panels. The hot press also has the characteristics of high pressure, low temperature and short film pressing time, which solves the deformation problem of workpieces processed by negative pressure equipment, greatly reduces the deformation degree of workpieces, and ensures the quality and performance of the product.

[0003] There are two ways to heat the hot plate on the traditional hot press. The high-temperature circulation pump inside the equipment will circulate the heat transfer oil or water vapor heated by the heating device in the pressure plate flow channel continuously, transfer the temperature to the hot plate, and then return to the heating device to continue heating, and repeat this cycle until the hot plate meets the requirements of the production industry. When the mold temperature controller detects that the template temperature reaches the set value, it stops heating. Although the working pressure of the electric heating heat transfer oil furnace of the hot press hot plate is relatively low, the temperature of the heat transfer fluid in the furnace is high, and most of them are flammable and explosive. Once a leak occurs during operation, it will cause a fire. Accidents such as explosions may even cause casualties and property losses. The supporting facilities of general small-scale processing plants are generally unable to cope with leakage, so steam heating is adopted. However, in the existing hot pressing equipment, water vapor will condense with the inner wall of the pressure plate flow channel during the circulation heating process in the pressure plate flow channel, thereby releasing heat, but the condensed water will still remain in the pressure plate flow channel, so that the condensed water will block the pressure plate flow channel when the equipment is used next time, thereby seriously reducing the heating efficiency of the heating plate. At the same time, when water vapor condenses into condensed water, some of the heat in the condensed water itself cannot be recycled.

[0004] Therefore, in order to solve the above problems, a hot pressing device for decorative panels based on wood grain paper veneer is proposed. Summary of the invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a decorative panel hot pressing equipment based on wood grain paper veneer, which can be provided with multiple feedback components in the heating chamber opened on the heating plate, and multiple conduction components are provided on both sides of the feedback components. While the water vapor releases heat to the conduction components, the conduction components can also collect the condensed liquid, and the condensed liquid is collected through the conduction components, thereby preventing the existence of a large amount of condensed liquid on the inner wall of the heating chamber when the water vapor condenses and releases heat and cannot be collected, thereby causing the equipment to reduce the heating efficiency due to the presence of condensed water when heating the heating plate next time. At the same time, the condensed liquid can be recycled through the feedback components, so that the condensed water with this part of the heat can be recycled and heated again into water vapor and transported to the heating chamber. Compared with heating water at room temperature, part of the energy can be saved, thereby improving the utilization rate of energy.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0010] Furthermore, a heat conducting plate is installed at one end of a pair of heating plates close to each other, and the heat conducting column, at one end away from the heating cavity, penetrates through the inner wall of the heating plate and extends to the outside of the heating plate and is fixedly connected to the heat conducting plate.

[0011] Furthermore, a plurality of evenly distributed collecting holes are provided on the heating plate, and a collecting cavity is provided on the heating plate, the plurality of collecting holes are connected to the collecting cavity, and the inner walls of the collecting holes are in contact with the feedback component.

The conduction components can make the water vapor entering the heating chamber contact with the conduction components to condense. While the water vapor releases heat to the conduction components, the conduction components can also collect the condensed liquid, and the condensed liquid is collected through the conduction components, thereby preventing the water vapor in the heating chamber from having a large amount of condensed liquid on the inner wall that cannot be collected when condensing and releasing heat, thereby reducing the heating efficiency of the equipment due to the presence of condensed water when heating the heating plate next time.

[0019] (2) This solution allows the condensed liquid to be recycled through a feedback component, so that the condensed water with this part of the heat can be recycled and heated again to become water vapor and transported to the heating chamber. Compared with heating water at room temperature, this can save some energy and improve the utilization rate of energy. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The first implementation method:

[0032] See also Figure 1-2 A hot pressing device for a decorative board based on wood grain paper veneer comprises a hot press machine 1, a pair of mutually symmetrical fixing columns 11 are fixedly connected at both ends of the top side of the hot press machine 1, a top plate 12 is fixedly connected to the outer periphery of the fixing columns 11 by bolts, a hydraulic rod 13 is fixedly connected to the top of the top plate 12, an output end of the hydraulic rod 13 penetrates the inner wall of the top plate 12 and extends to one end outside the top plate 12 and is fixedly connected to an extrusion block, a fine adjuster 14 is installed at the top of the hydraulic rod 13, a pressure gauge 15 is installed at the outer end of the hydraulic rod 13, and a plurality of fixing columns 11 are fixedly connected to the top plate 12. The outer enclosure is slidably connected with a pair of symmetrical fixed plates 3, the top of the upper fixed plate 3 is fixedly connected to the extrusion block, and the bottom of the lower fixed plate 3 is fixedly connected to the top of the hot press 1. A pair of fixed plates 3 are installed with a heating plate 31 at one end close to each other, and a heating cavity 32 is opened on the heating plate 31. A plurality of feedback components 4 are arranged in the heating cavity 32, and a plurality of conduction components 5 are arranged on both sides of the feedback component 4. In this scheme, a plurality of feedback components 4 are arranged in the heating cavity 32 opened on the heating plate 31, and a plurality of conduction components 5 are arranged on both sides of the feedback component 4. A plurality of conduction components 5 are arranged, so that through a plurality of feedback components 4 arranged in the heating chamber 32, the water vapor is transported to the heating chamber 32 opened on the heating plate 31 through the connecting pipe 21 through the heating device 2, and contacts with the inner wall of the heating chamber 32 to condense and release heat. The conduction component 5 can make the water vapor entering the heating chamber 32 contact with the conduction component 5 and condense. While the water vapor releases heat to the conduction component 5, the conduction component 5 can also collect the condensed liquid, and the condensed liquid is collected through the conduction component 5, so as to prevent the water vapor in the heating chamber 32 from having a large amount of condensed liquid on its inner wall when condensing and releasing heat, thereby causing the equipment to reduce the heating efficiency due to the presence of condensed water when heating the heating plate 31 next time. At the same time, the condensed liquid can be recycled through the feedback component 4, so that the condensed water of this part of the heat can be recycled and heated again into water vapor and transported to the heating chamber 32. Compared with heating water at room temperature, part of the energy can be saved, thereby improving the utilization rate of energy.

[0033] A heating device 2 is installed at one end of the hot press 1, and a pair of connecting pipes 21 are installed on the heating device 2. One end of the connecting pipe 21 is connected to a heating chamber 32 opened on the heating plate 31. In this scheme, a pair of connecting pipes 21 installed on the heating device 2 are connected to the heating chamber 32 opened on the heating chamber 32, so that water vapor can be transported to the heating chamber 32 through the connecting pipes 21 by the heating device 2, thereby completing the heating of the heating plate 31.

[0034] See also Figure 2-6 The conduction component 5 includes a heat-conducting column 51, the top of which is fixedly connected to the inner wall of the heating chamber 32, and a plurality of evenly distributed elastic fibers 52 are installed on the outer periphery of the heat-conducting column 51, and a heat-insulating pad 53 is installed in the accommodating cavity opened in the elastic fibers 52. In this scheme, a plurality of elastic fibers 52 are installed on the outer periphery of the heat-conducting column 51, so that when the heating device 2 transports water vapor to the heating chamber 32 opened on the heating plate 31 through the connecting pipe 21, the water vapor entering the heating chamber 32 contacts the plurality of elastic fibers 52 on the heat-conducting column 51 arranged in the heating chamber 32, thereby condensing and transferring the condensed heat to the elastic fibers 52. When a large amount of water vapor gathers on the elastic fibers 52, it falls to the inner wall of the heating chamber 32 under the action of the gravity of the condensed water. By setting the inner wall surface of the heating chamber 32 to be a plurality of curved shapes, the condensed water can be collected in the collecting hole 33.

[0035] A pair of heating plates 31 are installed with a heat conducting plate 35 at one end close to each other, and a heat conducting column 51 is away from the heating chamber 32, one end of the heat conducting column 51 penetrates the inner wall of the heating plate 31 and extends to the outside of the heating plate 31 and is fixedly connected to the heat conducting plate 35. In this scheme, one end of the heat conducting column 51 penetrates the inner wall of the heating plate 31 and is fixedly connected to the heat conducting plate 35, so that when condensed water contacts with multiple elastic fibers 52 arranged on the heat conducting column 51 to condense and release heat, the heat is transferred to the heat conducting column 51 through the multiple elastic fibers 52, and then transferred to the heat conducting plate 35 through the heat conducting column 51, thereby heating the heat conducting plate 35.

[0036] A plurality of evenly distributed collecting holes 33 are provided on the heating plate 31, and a collecting chamber 34 is provided on the heating plate 31, and the plurality of collecting holes 33 are connected to the collecting chamber 34, and the inner wall of the collecting hole 33 abuts against the feedback component 4. In this scheme, a plurality of evenly distributed collecting holes 33 are provided on the heating plate 31, and a collecting chamber 34 is provided on the heating plate 31, and the plurality of collecting holes 33 are connected to the collecting chamber 34, so that the condensed water in the heating chamber 32 can be collected through the plurality of collecting holes 33 provided on the heating plate 31, and the condensed water in the heating chamber 32 is collected by the plurality of collecting holes 33, so that the collected condensed water can enter the collecting chamber 34 together, and an air suction pump can be provided at one end outlet of the collecting chamber 34, so that the condensed water in the collecting chamber 34 can be sucked into the heating device 2 for heating again to generate water vapor, and because the condensed water in the collecting chamber 34 itself still has a certain amount of heat, the energy required for heating it is lower than that under normal temperature, thereby saving a certain amount of energy loss.

[0037] The feedback component 4 includes a hollow ball 41, which is filled with magnetic powder 42, and a sealing ring 43 matching the collecting hole 33 is installed on the outer periphery of the hollow ball 41. In this solution, the hollow ball 41 is filled with magnetic powder 42, and the sealing ring 43 matching the collecting hole 33 is installed on the outer periphery of the hollow ball 41, so that when the condensed water collected on the conductive component 5 falls to the inner wall of the heating chamber 32, and the shape of the inner wall of the heating chamber 32 is inclined to the side of the collecting hole 33, the collected condensed water flows to the collecting hole 33, and the hollow ball 41 abuts against the inner wall of the collecting hole 33, so that the collected condensed water gathers at the collecting hole 33. When a certain amount of condensed water gathers, the buoyancy generated by the condensed water on the hollow ball 41 becomes larger and larger, thereby floating the hollow ball 41 and separating it from the collecting hole 33. The inner wall of the hole 33 is in abutment with each other, so that the condensed water is collected by the collecting chamber 34. When the hollow ball 41 floats, the magnetic powder 42 is filled in the hollow ball 41, so that the magnetic powder 42 can generate attraction for the thermal insulation pad 53, so that the multiple elastic fibers 52 installed around the heat-conducting column 51 change from an inclined state to a relatively parallel state, so that the condensed water adsorbed on the outer surface of the elastic fiber 52 is difficult to fall off, so that the condensed water adsorbed on the outer surface of the elastic fiber 52 can continue to transfer heat to the heat-conducting column 51. At the same time, it also prevents the condensed water adsorbed on the outer surface of the elastic fiber 52 from continuing to drip when the hollow ball 41 floats up to collect the condensed water, so that the hollow ball 41 floats for a long time, resulting in heat loss in the heating chamber 32.

[0038] The outer surface of the thermal insulation pad 53 is provided with a magnetic strip 54, and the material of the magnetic strip 54 is set to be a thermal insulation material. In this solution, by setting the material of the magnetic strip 54 to be a thermal insulation material, heat can be better transferred to the side of the heating plate 31 close to the heat conducting plate 35, thereby preventing excessive heat from being transferred to the air through the heating plate 31 and causing waste.

[0039] A plurality of shaking rods 61 are installed at the top end of the heating chamber 32, and a gravity ball 62 is installed at one end of the shaking rods 61 close to the feedback component 4. In this scheme, the gravity ball 62 is installed at one end of the shaking rods 61 close to the feedback component 4, so that when water vapor enters the heating chamber 32, the shaking rods 61 can be driven to shake, so that the shaking rods 61 can drive the gravity ball 62 to shake, so that the inner wall of the heating chamber 32 can vibrate to a certain extent, so that the condensed water adsorbed on the upper inner wall of the heating chamber 32 can be shaken off.

[0040] The material of the magnetic powder 42 is set to be a magnetic material. In this solution, by setting the material of the magnetic powder 42 to be a magnetic material, the magnetic powder 42 can generate an attraction for the thermal insulation pad 53 installed in the elastic fiber 52, thereby preventing the hollow ball 41 from floating up under the action of condensed water to collect condensed water. The condensed water adsorbed on the outer surface of the elastic fiber 52 continues to drip down, causing the hollow ball 41 to float for a longer time and resulting in heat loss in the heating chamber 32.

[0041] The material of the elastic fiber 52 is set to be an elastic thermally conductive material. In this solution, the material of the elastic fiber 52 is set to be an elastic thermally conductive material, so that when the hollow ball 41 floats up under the action of condensed water to collect condensed water, the magnetic powder 42 generates an attraction for the thermal insulation pad 53 installed in the elastic fiber 52, so that the elastic fiber 52 can be deformed.

[0042] Working principle: When the device is working, the device switch is turned on, so that the water vapor is transported to the heating chamber 32 opened on the heating plate 31 through the connecting pipe 21 through the heating device 2, and condenses and releases heat by contacting the inner wall of the heating chamber 32. At the same time, the water vapor entering the heating chamber 32 contacts the multiple elastic fibers 52 on the heat-conducting column 51 provided in the heating chamber 32, thereby condensing and transferring the condensed heat to the elastic fibers 52. When the water vapor gathers more on the elastic fibers 52, the condensed water is heated by the gravity. The condensed water drips down to the inner wall of the heating chamber 32. By setting the inner wall surface of the heating chamber 32 to be a plurality of curved surfaces, the condensed water can be collected in the collecting hole 33. The hollow ball 41 abuts against the inner wall of the collecting hole 33, so that the collected condensed water gathers at the collecting hole 33. When a certain amount of condensed water is gathered, the buoyancy generated by the hollow ball 41 becomes greater and greater, so that the hollow ball 41 floats up and is separated from the abutment state with the inner wall of the collecting hole 33, so that the condensed water is collected by the collecting chamber 34. In the floating state, the hollow ball 41 is filled with magnetic powder 42, so that the magnetic powder 42 can generate attraction for the thermal insulation pad 53, so that the multiple elastic fibers 52 installed around the heat-conducting column 51 change from an inclined state to a relatively parallel state, so that the condensed water adsorbed on the outer surface of the elastic fiber 52 is difficult to fall off, and the condensed water adsorbed on the outer surface of the elastic fiber 52 can continue to transfer heat to the heat-conducting column 51. At the same time, it also prevents the condensed water adsorbed on the outer surface of the elastic fiber 52 from continuing to drip when the hollow ball 41 floats up to collect the condensed water, thereby causing the hollow ball 41 to float for a long time and causing heat loss in the heating chamber 32. By providing an air suction pump at the outlet of one end of the collecting chamber 34, the condensed water in the collecting chamber 34 can be sucked into the heating device 2 for heating again to generate water vapor. Because the condensed water in the collecting chamber 34 itself still has a certain amount of heat, the energy required to heat it is lower than that at normal temperature, thereby saving a certain amount of energy loss.

[0043] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
