Description

Technical Field

[0001] The utility model relates to the technical field of industrial heating equipment, in particular to a plate heating device for heating a plate. Background Art

[0002] Lightweighting of automobiles is one of the most effective measures to save energy, improve power, braking performance and endurance. It is also one of the three major development directions of the automobile industry (new energy, unmanned driving, and lightweighting). Lightweight reinforced composite materials are an important trend in achieving lightweighting, such as fiber-reinforced composite products.

[0003] In order to meet the requirements of green environmental protection and low carbonization, more and more automotive interior panels are using fiber-reinforced composite products, such as Figure 1 and Figure 2 The automotive interior panel shown is formed by hot pressing, punching and injection molding using hemp fiberboard as the base panel. The hemp fiberboard is formed into a hot pressing panel portion of a fiber reinforced composite product with a certain contour shape by hot pressing and punching, and the back of the hot pressing panel portion is formed into a plastic portion of the fiber reinforced composite product by injection molding. This automotive interior panel has the characteristics of low density, high modulus and strength, and is very suitable for lightweight automotive parts.

[0004] Hemp fiberboard needs to have a high temperature and pressure during hot pressing. It is hot pressed in the mold under high temperature and pressure to form a solid board. In order to shorten the molding cycle, the board is usually heated outside the mold before being placed in the mold, and then placed in the mold after heating. In this way, while the previous board is being hot pressed, punched, and injection molded in the mold, the next board can be heated outside the mold at the same time, so as to shorten the production cycle and improve production efficiency.

[0005] In the prior art, the heating equipment for such plates usually only has two relative integral heating components. During hot pressing, the temperature of the hot-pressed plates is usually only required to be high at the forming part, while the temperature of the surrounding parts is required to be low. The existing integral heating components cannot perform different temperature control according to the different temperature requirements of different areas of the plate, resulting in high energy consumption and high heating costs, and cannot be used to heat different plates with different temperature requirements.

[0050] Hot pressing is to put resin, wood or other thermoplastic matrix sheets into a mold and press them under high temperature and pressure to form a solid sheet. The hot pressed sheets are often used in furniture, decoration, construction and other fields, and have the advantages of wear resistance, pressure resistance and waterproofness. Figure 1 and Figure 2 The fiber-reinforced composite product shown in the figure has a base of hemp fiberboard. Before hot pressing, the hemp fiberboard is flat, soft, low in density, loose and porous. After hot pressing, it becomes a board with greater hardness and a certain shape, i.e. Figure 1 , Figure 2 The hot press formed part 10 shown in FIG. 1 has increased strength, high density and compactness, and reduced thickness.

[0051] If the unheated raw material is directly placed in the hot pressing mold, the raw material must be heated to the corresponding temperature first, resulting in a long hot pressing production cycle and low production efficiency. To solve this problem, in some embodiments of the present application, a plate heating device is provided, which is used to heat the raw material plate a (usually a thermoplastic plate) to be hot pressed outside the mold before placing it into the hot pressing mold, and then put it into the mold after heating. In this way, the hot pressing of the previous plate a and other processes such as punching, injection molding (such as Figure 1 , Figure 2In the fiber reinforced composite product shown, during the process of injection molding the plastic part 20 on the back side of the thermoforming part 10, the latter sheet a can be heated outside the mold at the same time to shorten the production cycle and improve production efficiency.

[0052] In some embodiments of the present application, reference Figures 3 to 6 ,as well as Figure 8 The plate heating device 2 includes a first heating cabinet 100 and a second heating cabinet 200.

[0053] The first heating cabinet 100 and the second heating cabinet 200 have the same structure, and the outer contour is a rectangular cabinet body 120. The cabinet body 120 may be provided with heat dissipation holes 110 for heat dissipation.

[0054] Among them, the first heating cabinet 100 includes a cabinet body 120 and a radiation heating component arranged in the cabinet body 120. One side of the cabinet body 120 is open to form a cabinet opening. To distinguish it from the cabinet opening of the second heating cabinet 200 described below, the cabinet opening of the first heating cabinet 100 is called the first cabinet opening 150; the radiation heating component includes a plurality of radiation heating components 130, and the radiation heating surface of the radiation heating component 130 faces the first cabinet opening 150. The plurality of radiation heating components 130 are arranged in a plane A, and the plane A is parallel to the plane where the first cabinet opening 150 is located.

[0055] Similarly, the second heating cabinet 200 also includes a cabinet body 120 and a radiation heating component disposed in the cabinet body 120. One side of the cabinet body 120 of the second heating cabinet 200 is open to form a cabinet opening. To distinguish it from the cabinet opening of the first heating cabinet 100, the cabinet opening of the second heating cabinet 200 is called a second cabinet opening 210. The direction of the second cabinet opening 210 is opposite to the direction of the first cabinet opening 150. For example, the first cabinet opening 150 is oriented in a first direction, and the second cabinet opening 210 is oriented in a second direction opposite to the first direction. A plate heating gap 400 is formed between the second heating cabinet 200 and the first heating cabinet 100. The multiple radiation heating components 130 of the second heating cabinet 200 are arranged in plane B, and plane B is parallel to the plane where the second cabinet opening 210 is located.

[0056] When the plate a is placed in the plate heating gap 400 for heating in a posture parallel to the plane where the first cabinet opening 150 is located (or the plane where the second cabinet opening 210 is located), the first heating cabinet 100 and the second heating cabinet 200 both work to heat the plate a from two opposite sides of the plate a to improve the heating efficiency; and for the plate a with thermal insulation function, such as hemp fiber board, carbon fiber board, etc., heating on both sides can also heat the plate a as thoroughly as possible so that it can be hot-pressed.

[0057] The multiple radiation heating components 130 of the first heating cabinet 100 and the second heating cabinet 200 are all equipped with independently controlled temperature control devices, that is, the temperature control devices are arranged one by one with the radiation heating components 130, so that each radiation heating component 130 can be independently temperature controlled. The set heating temperature of each radiation heating component 130 can be different, or divided by area, each area includes several adjacent radiation heating components 130, and the set heating temperature of the radiation heating components 130 contained in each area is the same, but different from the set heating temperature of the radiation heating components 130 in other areas, depending on the specific type of the plate a to be heated. By independently controlling the temperature of each radiation heating component 130, the zoned temperature control of the plate heating device 2 can be achieved, making the temperature control more accurate and more targeted, meeting the different requirements for heating temperature of different areas of the same plate a, which is conducive to reducing production costs, and can also be controlled by zones to match plates of different sizes, thereby improving the general flexibility of the plate heating device 2.

[0058] For the hemp fiberboard, since the central part is the main hot-pressing forming part, the radiation heating components 130 in the first heating cabinet 100 and the second heating cabinet 200 corresponding to the main hot-pressing forming part on the hemp fiberboard are set to have a higher heating temperature, and the temperature of the remaining parts is lower to save energy consumption.

[0059] In some embodiments of the present application, the radiation heating component 130 is an infrared ceramic heating plate, which has a high thermal radiation coefficient, high heating efficiency, a high upper temperature limit, and a large effective wavelength.

[0060] In some embodiments of the present application, the radiation heating component 130 may also be an infrared quartz heating plate or the like.

[0061] Since the plate a to be heated is usually relatively small in thickness, about 10 mm, in order to fully heat the plate a, the distance between the first heating cabinet 100 and the second heating cabinet 200, that is, the width w of the plate heating gap 400 should not be too large, preferably 20-30 mm.

[0062] For the temperature control device, in some embodiments of the present application, it includes a power supply, a thermostat and a temperature sensor; the thermostat is electrically connected to the power supply, the temperature sensor is electrically connected to the power supply, the radiation heating component 130 is electrically connected to the power supply, and an electronic switch is arranged on the connection line between the radiation heating component 130 and the power supply, and the electronic switch is used to switch on and off the line in which it is located; the thermostat is communicatively connected to the temperature sensor, the thermostat is connected to the electronic switch, and the temperature sensor is arranged near the radiation heating component 130 to detect the temperature at the radiation heating component 130.

[0063] The temperature sensor sends the detected temperature information to the thermostat, and the thermostat determines whether to open or close the electronic switch according to the received temperature information detected by the temperature sensor.

[0064] Taking one of the radiation heating components 130 as an example, when the temperature information detected by its corresponding temperature sensor is greater than the set heating temperature of the radiation heating component 130, the thermostat controls the electronic switch to close, so that the radiation heating component 130 is disconnected from the power supply, and the radiation heating component 130 is no longer heated; when the temperature information detected by the temperature sensor is less than the set heating temperature of the corresponding radiation heating component 130, the thermostat controls the electronic switch to open, so that the radiation heating component 130 is connected to the power supply, and the radiation heating component 130 works to heat.

[0065] In some embodiments of the present application, the multiple radiation heating components 130 of the first heating cabinet 100 and the multiple radiation heating components of the second heating cabinet 200 are arranged one by one so that each part of the plate a can be heated symmetrically on both sides, thereby improving the heating effect and heating efficiency.

[0066] In some embodiments of the present application, the plurality of radiation heating components 130 of the first heating cabinet 100 are arranged at equal intervals, such as Figure 8 As shown, correspondingly, the plurality of radiation heating components of the second heating cabinet 200 are arranged at equal intervals.

[0067] by Figure 8 For example, the radiation heating assembly in the first heating cabinet 100 includes 6 rows and 4 columns, totaling 24 radiation heating components 130, and the radiation heating assembly in the second heating cabinet 200 includes 6 rows and 4 columns, totaling 24 radiation heating components 130, that is, a total of 48 radiation heating components 130 on both sides. Each radiation heating component 130 is individually controlled and is respectively equipped with a temperature sensor, so that the zone control can achieve more accurate temperature control, and each radiation heating component 130 can be controlled individually or by zone control to match plates a of different sizes.

[0068] For the hemp fiberboard whose central part is the main hot pressing forming part, a plurality of radiation heating components 130 (such as Figure 8 The eight radiation heating components 130 in the middle are set to a higher heating temperature, and the multiple radiation heating components 130 on the periphery (such as Figure 8 The 16 radiation heating components 130 at the periphery are set to a lower heating temperature to save energy.

[0069] Taking the first heating cabinet 100 as an example, Figures 6 to 8As shown, the radiation heating assembly also includes a mounting bracket 160, and the plurality of radiation heating components 130 are specifically mounted in the first heating cabinet 100 through the mounting bracket 160. The mounting bracket 160 includes an annular frame 161 and a mounting plate 162 fixed on the annular frame 161. The outer contour of the annular frame 161 is adapted to the inner contour of the cabinet body 120 of the first heating cabinet 100, and can be mounted in the cabinet body 120 of the first heating cabinet 100 by welding or screw connection; the mounting plate 162 faces the side where the second heating cabinet 200 is located, and the plurality of radiation heating components 130 can be arranged on the mounting plate 162 in a rectangular array and face the side where the second heating cabinet 200 is located, and can be specifically fastened to the mounting plate 162 by screws.

[0070] The structure of the radiation heating assembly in the second heating cabinet 200 is the same as that of the radiation heating assembly in the first heating cabinet 100, and will not be described in detail here.

[0071] In some embodiments of the present application, wire holes 163 are formed on the mounting plate 162 at positions corresponding to the radiation heating components 130 to facilitate the routing of connection wires between the radiation heating components 130 and the power supply.

[0072] As for the method of taking and placing the plate a into the plate heating gap 400, it can be taken and placed by a robot or manually.

[0073] In some embodiments of the present application, the plate heating device 2 also includes a base 300, and the first heating cabinet 100 and the second heating cabinet 200 are relatively arranged on the base 300, and the first heating cabinet 100 and the second heating cabinet 200 can be fixed on the base 300 in a detachable manner.

[0074] In some embodiments of the present application, one of the first heating cabinet 100 and the second heating cabinet 200 may be fixedly arranged and the other movably arranged, for example, the second heating cabinet 200 is fixedly arranged on the base 300, and the first heating cabinet 100 is slidably arranged on the base 300.

[0075] In order to realize the sliding of the first heating cabinet 100, in some embodiments of the present application, the plate heating equipment 2 also includes a linear reciprocating motion mechanism, which is used to drive the first heating cabinet 100 to move linearly and reciprocatingly on the base 300, that is, reciprocating linear sliding, so that the first heating cabinet 100 has a closed position opposite to the second heating cabinet 200 and an open position staggered with the second heating cabinet 200.

[0076] When the plate heating device 2 is working to heat the plate a, the first heating cabinet 100 and the second heating cabinet 200 are facing each other. Figure 3 and Figure 4As shown, the double-sided heating of the plate a is normally performed; when manually placing or placing the parts or observing the heating condition of the plate a, the linear reciprocating motion mechanism can be operated to move the first heating cabinet 100 to the open position, referring to Fig.10 as shown for easy operation or observation.

[0077] In some embodiments of the present application, the linear reciprocating motion mechanism may be a cylinder or oil cylinder drive mechanism, and the piston rod of the cylinder or oil cylinder is connected to the cabinet 120 of the first heating cabinet 100. Alternatively, the linear reciprocating motion mechanism is a ball screw slider mechanism driven by a motor, and the cabinet 120 of the first heating cabinet 100 is connected to the slider.

[0078] In order to guide the reciprocating linear motion of the first heating cabinet 100, a sliding guide mechanism 500 is provided between the base 300 and the cabinet body 120 of the first heating cabinet 100, such as a guide rail slider mechanism. The guide rail can be fixed on the base 300, and the slider can be fixed on the bottom plate of the cabinet body 120. Pushing and pulling the first heating cabinet 100 can realize its reciprocating sliding on the base 300 along the guide rail direction.

[0079] Of course, the linear reciprocating motion of the first heating cabinet 100 can also be manually operated. In this case, it is also necessary to set a sliding guide mechanism 500 between the base 300 and the cabinet body 120 of the first heating cabinet 100, such as a guide rail slider mechanism. The guide rail can be fixed on the base 300, and the slider can be fixed on the bottom plate of the cabinet body 120. Pushing and pulling the first heating cabinet 100 can realize its reciprocating sliding along the guide rail direction on the base 300.

[0080] In the case of placing the plate a into the plate heating gap 400 by means of a robot, the robot can directly keep holding the plate a during heating, and can directly take it out by the robot after heating is completed. In the case of manual placement, a corresponding plate placement structure needs to be set in the heating device to place the plate for heating.

[0081] In some embodiments of the present application, a plate hanging portion (not shown) is provided at the first cabinet opening 150 of the first heating cabinet 100, or a plate hanging portion is provided at the second cabinet opening 210 of the second heating cabinet 200. When manually placing the pieces, the plate a can be hung on the plate hanging portion.

[0082] In some embodiments of the present application, a plate hanging portion is provided at the first cabinet opening 150 of the first heating cabinet 100, and a plate hanging portion is also provided at the second cabinet opening 210 of the second heating cabinet 200. When manually placing the plate, the plate a can be placed on the plate hanging portion of the first heating cabinet 100 or the plate hanging portion of the second heating cabinet 200, or the plate can be hung on both the plate hanging portion of the first heating cabinet 100 and the plate hanging portion of the second heating cabinet 200, so as to achieve simultaneous heating of multiple small-sized plates.

[0083] The plate hanging portion extends into the plate heating gap 400, so that after the plate is hung, the position of plate a is as close as possible to the middle of the width of the plate heating gap 400, so that the distances between its two sides and the radiation heating components 130 in the first heating cabinet 100 and the radiation heating components 130 in the second heating cabinet 200 are as equal as possible to improve the heating effect.

[0084] In some embodiments of the present application, the plate hanging portion may be a high temperature resistant detachable hook, such as a hot dip galvanized + Teflon treated hook.

[0085] In some embodiments of the present application, the first cabinet opening 150 of the first heating cabinet 100 is covered with a high-temperature resistant mesh protective component 140, and the second cabinet opening 210 of the second heating cabinet 200 is also covered with a high-temperature resistant mesh protective component 140 to separate the plate a and the radiation heating component 130 to prevent the plate a from sticking to or burning the radiation heating component 130.

[0086] The periphery of the mesh protection component 140 can be fixed on the cabinet body 120 plate around the cabinet opening by screw fastening, and the mesh protection component 140 can be treated by hot-dip galvanizing + Teflon to be resistant to high temperatures.

[0087] Correspondingly, if a detachable hook is provided, the hook can be hung on the mesh protection component 140, and the hanging position can be flexibly changed to be compatible with the requirements of different hanging point positions of various panels.

[0088] In addition, for the plate a that may curl and deform after heating, the first cabinet opening 150 and the second cabinet opening 210 are covered with a high temperature resistant mesh protection component 140, and the mesh protection components 140 on both sides can also support and limit the heating plate a in the middle to prevent it from deforming during heating. Specifically, if the plate a curls to one side, its curled portion will hit the mesh protection component 140 on this side, and the mesh protection component 140 will resist and limit the further curling and deformation of the plate a.

[0089] In order to facilitate the placement and hanging heating of the plate a, in some embodiments of the present application, the first heating cabinet 100 and the second heating cabinet 200 are both vertical heating cabinets, and the first cabinet opening 150 and the second cabinet opening 210 are both horizontally oriented. Figure 3 In the perspective shown, the first cabinet opening 150 is horizontally facing right, and the second cabinet opening 210 is horizontally facing left. The robot clamps the plate a and inserts it into the plate heating gap 400 between the first heating cabinet 100 and the second heating cabinet 200 from above, or slides the first heating cabinet 100 horizontally to an open position offset from the second heating cabinet 200, manually hangs the plate on the plate hanging part, and then returns the first heating cabinet 100 to the closed position to heat the plate.

[0090] Due to different board materials a, the distance between the first heating cabinet 100 and the second heating cabinet 200 is different, that is, the width w of the board heating gap 400 is different, so as to evenly absorb the heat radiation. For example, for a fiber mat with an area density of 1400, the distance needs to be closer, that is, the width of the board heating gap 400 needs to be smaller, and for a PC board, the distance needs to be farther, that is, the width of the board heating gap 400 needs to be larger.

[0091] In order to achieve adjustable width of the plate heating gap 400, in some embodiments of the present application, the second heating cabinet 200 is configured to be movable toward or away from the first heating cabinet 100 to adjust the width of the plate heating gap 400. Along the arrangement direction of the first heating cabinet 100 and the second heating cabinet 200, a plurality of spaced screw holes 310 are formed on the base 300, and correspondingly, a plurality of spaced mounting holes 220 are also formed on the bottom plate of the cabinet body 120 of the second heating cabinet 200. After the second heating cabinet 200 is moved into place along the direction toward or away from the first heating cabinet 100, the aligned mounting holes 220 and the screw holes 310 are fastened by screws.

[0092] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0093] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
