Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of decorative plate hot pressing equipment, in particular to a decorative plate hot pressing equipment based on wood grain paper skin. BACKGROUND

[0002] The main machine of the hot press can be divided into three parts: a heating system (providing a heat source), a hydraulic system (providing pressure and controlling the action of the press), and a press body (a frame, a 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 plate. The hot press also has the characteristics of large pressure, low temperature, and short film pressure time, which solves the deformation problem of workpieces processed by negative pressure equipment, greatly reduces the degree of deformation of workpieces, and ensures the quality and performance of products.

[0003] There are two heating methods for the hot pressing plate on the traditional hot press. The high-temperature circulating pump in the equipment continuously circulates the heat-conducting oil or water vapor heated by the heating device in the pressing plate flow channel, transfers the temperature to the hot pressing plate, and then returns to the heating device for continuous heating. This cycle is repeated until the hot pressing plate meets the requirements of the production industry. When the mold temperature machine detects that the mold temperature reaches the set value, heating is stopped. The working pressure of the hot pressing plate electric heating heat-conducting oil furnace of the hot press is relatively low, but the temperature of the heat-conducting liquid in the furnace is high, and it mostly has the characteristics of being flammable and explosive. Once a leak occurs during operation, it will cause fires, explosions and other accidents, and even cause personnel injuries and property losses. Therefore, it is difficult for general small processing plants to cope with the situation of leakage, so steam heating is used. However, in the process of circulating heating of water vapor in the pressing plate flow channel of the existing hot pressing equipment, the water vapor will condense on the inner wall of the flow channel and then release heat. However, the condensed water still exists in the pressing plate flow channel, which will block the pressing 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 the water vapor condenses into condensed water, a part of the heat of the condensed water cannot be recycled.

[0004] Therefore, a decorative plate hot pressing equipment based on wood grain paper skin is proposed to solve the above problems. SUMMARY

[0005] To address the problems existing in the prior art, the present invention aims to provide a hot-pressing device for decorative panels based on wood grain paper veneer. This device features a heating chamber on a heating plate with multiple feedback components and multiple conduction components on both sides. While water vapor releases heat to the conduction components, the components also collect the condensed liquid. This collection prevents excessive condensation from forming on the inner wall of the heating chamber during the condensation process, which would otherwise reduce heating efficiency during subsequent heating of the heating plate. Furthermore, the feedback components allow for the recycling of the condensed liquid, enabling it to be reheated into steam and returned to the heating chamber. Compared to heating room-temperature water, this method saves energy and improves energy utilization.

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

Multiple conduction components are arranged on both sides of each feedback component.

[0008] Furthermore, a heating device is installed at one end of the hot press, and a pair of connecting pipes are installed on the heating device. One end of the connecting pipes is connected to a heating cavity opened on the heating plate.

[0010] Furthermore, a heat-conducting plate is installed at one end of each of the two heating plates close to each other, and the end of the heat-conducting column away from the heating cavity penetrates the inner wall of the heating plate and extends to the outer side of the heating plate, where it is fixedly connected to the heat-conducting plate.

[0011] Further, a plurality of collecting holes are evenly distributed on the heating plate, and a collecting cavity is formed on the heating plate, the collecting holes are communicated with the collecting cavity, and the inner wall of the collecting hole is in abutment with the feedback assembly.

[0012] Further, the feedback assembly comprises a hollow ball, the hollow ball is filled with magnetic powder, and a sealing ring matched with the collecting hole is mounted outside the hollow ball.

[0031] First embodiment:

[0032] Please refer to Figures 1-2 A kind of wood grain paper veneer-based decorative plate hot-pressing equipment, including hot press 1, the top side of hot press 1 both ends are fixedly connected with a pair of mutually symmetrical fixed column 11, fixed column 11 is surrounded by bolted connection with top plate 12, top plate 12 top end is fixedly connected with hydraulic rod 13, the output end of hydraulic rod 13 penetrates the inner wall of top plate 12 and extends to the one end of top plate 12 outside and is fixedly connected with extrusion block, and the top end of hydraulic rod 13 is installed with micro-adjuster 14, pressure gauge 15 is installed on the outer end of hydraulic rod 13, a plurality of fixed column 11 is surrounded and is slidably connected with a pair of mutually symmetrical fixed plate 3, the top end of upper fixed plate 3 is fixedly connected with extrusion block, the bottom end of lower fixed plate 3 is fixedly connected with the top end of hot press 1, a pair of fixed plate 3 are installed with heating plate 31 at the end of mutual approach, heating cavity 32 is opened in heating plate 31, a plurality of feedback components 4 are arranged in heating cavity 32, a plurality of conduction components 5 are arranged on the both sides of feedback component 4, in the present application, a plurality of feedback components 4 are arranged in heating cavity 32 opened in heating plate 31, and a plurality of conduction components 5 are arranged on the both sides of feedback component 4, so that a plurality of feedback components 4 arranged in heating cavity 32 can be condensed by heating device 2 to heat cavity 32 and contact the inner wall of heating cavity 32 to release heat, water vapor can be condensed into contact with conduction component 5 by conduction component 5, while water vapor releases heat to conduction component 5, conduction component 5 can also collect condensed liquid, and the condensed liquid is collected by conduction component 5, so that when the water vapor in heating cavity 32 is condensed and released, the condensed liquid on the inner wall of heating cavity 32 cannot be collected, which reduces the heating efficiency due to the existence of condensed water when the heating plate 31 is heated next time, and the condensed water is recycled by feedback component 4, so that the part of heat can be recovered and heated into water vapor to be delivered to heating cavity 32, compared with heating normal temperature water, a part of energy can be saved, and the utilization rate of energy is improved.

[0033] The heating device 2 is provided with a pair of connecting pipes 21, one end of the connecting pipes 21 is communicated with the heating cavity 32 of the heating plate 31, the water vapor is delivered to the heating cavity 32 through the connecting pipes 21 by the heating device 2, so that the heating plate 31 is heated.

[0034] Please refer to Figures 2-6 The heat conduction assembly 5 comprises a heat conduction column 51, the top end of the heat conduction column 51 is fixedly connected with the inner wall of the heating cavity 32, a plurality of elastic fibers 52 are uniformly arranged outside the heat conduction column 51, and a heat insulation pad 53 is arranged in the accommodating cavity of the elastic fiber 52, the water vapor in the heating cavity 32 is in contact with the plurality of elastic fibers 52 on the heat conduction column 51, so that condensation occurs and the condensed heat is transmitted to the elastic fiber 52, when the water vapor is gathered on the elastic fiber 52, the condensed water falls to the inner wall of the heating cavity 32 under the action of gravity, and the inner wall surface of the heating cavity 32 is provided in a plurality of curved shapes, so that the condensed water is collected into the collecting hole 33.

[0035] One end of the pair of heating plates 31 is provided with a heat conduction plate 35, one end of the heat conduction column 51 penetrating through the inner wall of the heating plate 31 and extending to the outer side of the heating plate 31 is fixedly connected with the heat conduction plate 35, the heat conduction column 51 is fixedly connected with the heat conduction plate 35, so that the heat is transmitted to the heat conduction plate 35 through the heat conduction column 51 after the condensed water is in contact with the plurality of elastic fibers 52 arranged on the heat conduction column 51, and the heat conduction plate 35 is heated.

[0036] A plurality of collection holes 33 are evenly distributed on the heating plate 31, and a collection cavity 34 is arranged on the heating plate 31, the plurality of collection holes 33 are communicated with the collection cavity 34, and the inner wall of the collection hole 33 abuts against the feedback assembly 4. According to the scheme, the plurality of collection holes 33 are evenly distributed on the heating plate 31, and the collection cavity 34 is arranged on the heating plate 31 and communicated with the plurality of collection holes 33. The condensed water in the heating cavity 32 can be collected through the plurality of collection holes 33 arranged on the heating plate 31. The condensed water in the heating cavity 32 is collected through the plurality of collection holes 33, so that the collected condensed water can enter the collection cavity 34 together. An air suction pump can be arranged at one end of the outlet of the collection cavity 34, so that the condensed water in the collection cavity 34 can be sucked into the heating device 2 for heating to generate water vapor again. Since the condensed water in the collection cavity 34 itself still has a certain amount of heat, the energy required for heating is lower than that in the normal temperature state, thereby saving a certain amount of energy loss.

[0037] The feedback assembly 4 comprises a hollow ball 41, the hollow ball 41 is filled with magnetic powder 42, and a sealing ring 43 matched with the collection hole 33 is arranged outside the hollow ball 41. According to the scheme, the hollow ball 41 is filled with magnetic powder 42, and the sealing ring 43 matched with the collection hole 33 is arranged outside the hollow ball 41. When the condensed water collected on the conduction assembly 5 falls to the inner wall of the heating cavity 32, and the shape of the inner wall of the heating cavity 32 is inclined to one side of the collection hole 33, the condensed water flows to the collection hole 33. The hollow ball 41 abuts against the inner wall of the collection hole 33, so that the condensed water is collected in the collection hole 33. When the amount of the condensed water collected reaches a certain amount, the buoyancy of the condensed water on the hollow ball 41 becomes larger and larger, so that the hollow ball 41 is floated to separate from the inner wall of the collection hole 33. The condensed water is collected in the collection cavity 34. When the hollow ball 41 is floated, the hollow ball 41 is filled with magnetic powder 42, so that the magnetic powder 42 can generate an attractive force on the heat-conducting column 51, so that the plurality of elastic fibers 52 arranged outside the heat-conducting column 51 change from the inclined state to the parallel state. Therefore, the condensed water adsorbed on the outer surface of the elastic fiber 52 is difficult to fall down, 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, the condensed water adsorbed on the outer surface of the elastic fiber 52 is prevented from falling down when the hollow ball 41 is floated to collect the condensed water, so that the time for the hollow ball 41 to float is longer, and the heat loss in the heating cavity 32 is reduced.

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

[0039] A plurality of shaking rods 61 are installed at the top end of the heating cavity 32, and a gravity ball 62 is installed at one end of the plurality of shaking rods 61 close to the feedback assembly 4. Through the installation of the gravity ball 62 at one end of the shaking rod 61 close to the feedback assembly 4, when water vapor enters the heating cavity 32, the shaking rod 61 can be shaken, thereby enabling the gravity ball 62 to be shaken by the shaking rod 61 to cause the inner wall of the heating cavity 32 to vibrate, so that the condensed water adsorbed on the upper inner wall of the heating cavity 32 can be shaken off.

[0040] The material of the magnetic powder 42 is set as a magnet material. Through the setting of the material of the magnetic powder 42 as a magnet material, the elastic fiber 52 can be attracted to the heat insulation pad 53 installed in the elastic fiber 52 by the magnetic powder 42, thereby preventing the condensed water adsorbed on the outer surface of the elastic fiber 52 from continuing to drop down when the hollow ball 41 floats up to collect the condensed water under the action of the condensed water, thereby causing the hollow ball 41 to float up for a long time and causing heat loss in the heating cavity 32.

[0041] The material of the elastic fiber 52 is set as an elastic heat-conducting material. Through the setting of the material of the elastic fiber 52 as an elastic heat-conducting material, when the hollow ball 41 floats up to collect the condensed water under the action of the condensed water, the elastic fiber 52 can be deformed by the magnetic powder 42 generating an attractive force to the heat insulation pad 53 installed in the elastic fiber 52.

[0042] Working principle: when the device is working, the device switch is started, so that the water vapor is transported to the heating cavity 32 on the heating plate 31 through the connecting pipe 21 and contacts the inner wall of the heating cavity 32 to condense and release heat, and the water vapor entering the heating cavity 32 contacts the multiple elastic fibers 52 on the heat conducting column 51 arranged in the heating cavity 32, so that condensation occurs and the condensed heat is transmitted to the elastic fibers 52, when the water vapor gathers on the elastic fibers 52, the condensed water drops to the inner wall of the heating cavity 32 under the action of gravity, the inner wall surface of the heating cavity 32 is arranged in multiple curved shapes, so that the condensed water can be collected into the collection hole 33, the hollow ball 41 abuts against the inner wall of the collection hole 33, so that the collected condensed water is gathered at the collection hole 33, when the amount of the collected condensed water reaches a certain amount, the buoyancy of the condensed water on the hollow ball 41 becomes larger and larger, so that the hollow ball 41 floats up and separates from the state of abutting against the inner wall of the collection hole 33, so that the condensed water is collected in the collection cavity 34, in the state that the hollow ball 41 floats up, the hollow ball 41 is filled with magnetic powder 42, so that the magnetic powder 42 can generate an attractive force on the heat insulation pad 53, so that the multiple elastic fibers 52 installed outside 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 fibers 52 is difficult to fall down, so that the condensed water adsorbed on the outer surface of the elastic fibers 52 can continue to transmit heat to the heat conducting column 51, and also prevent the condensed water adsorbed on the outer surface of the elastic fibers 52 from falling down when the hollow ball 41 floats up to collect the condensed water, so that the time for the hollow ball 41 to float up is longer, resulting in heat loss in the heating cavity 32, an air suction pump can be arranged at one end of the outlet of the collection cavity 34, so that the condensed water in the collection cavity 34 can be sucked into the heating device 2 for heating to generate water vapor again, because the condensed water in the collection cavity 34 itself still has a certain amount of heat, so that the energy required for heating is lower than that in the normal temperature state, and energy loss is saved.

[0043] The above is only a preferred specific embodiment of the present application; however, the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical solution and improvement concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
