Technical Field
[0001] The utility model relates to the technical field of composite board production, in particular to an infrared drying oven for composite boards. Background Art
[0002] Composite board is a kind of board composed of layers of materials with different functions. There are many types of composite boards, including metal composite boards, wood composite boards, color steel composite boards, rock wool composite boards, etc. These composite boards all require core materials.
[0003] At present, the core material needs to be dried in an oven in the market to soften it, so that during the production process of the composite board, the core layer board and the upper layer board, and the core layer board and the lower layer board can be bonded with glue or polymer film.
[0004] The traditional drying oven is relatively simple, consisting of a box body and an electric heating tube. When drying, the rolled core material is placed in the drying oven, and then the electric heating tube is used to heat the core material. Since this method only uses electric heating equipment to heat the core material, the energy consumption is high. In addition, in the early stage of drying, a large amount of heat is used to heat up the entire interior of the box, so the efficiency is not good. Utility Model Content
[0005] The main purpose of the utility model is to provide an infrared drying oven for composite panels. When the interior of the box is initially heated, the electric heater and the infrared heater are turned on simultaneously. The infrared heater is mainly used for drying the core material, and the electric heater is mainly used for increasing the temperature of the box. The two heaters work together to speed up the heating speed of the box and reduce the time required for drying and softening the core material. Moreover, when the temperature inside the box reaches the required range, the electric heater is turned off and only the infrared heater is used to dry the core material, thereby reducing energy consumption and reducing costs.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A composite board infrared oven comprises a box body with an opening on one side, wherein the box body is divided into an upper cavity and a lower cavity by a partition, an upper bracket is slidably connected to the upper cavity by a first sliding component, and a lower bracket is slidably connected to the lower cavity by a second sliding component, infrared heaters are respectively arranged on the top of the upper cavity and the top of the lower cavity, and electric heaters are also installed in the upper cavity and the lower cavity.
[0008] Furthermore, the upper bracket and the lower bracket have the same structure and are both composed of a bearing plate, a vertical plate and a roller body. The roller body is rotatably connected to the vertical plate and the vertical plate is fixedly connected to the bearing plate.
[0009] Furthermore, a motor is connected to the vertical plate of the lower bracket, and an output shaft of the motor is fixedly connected to the roller body of the lower bracket.
[0010] Furthermore, the first sliding assembly and the second sliding assembly have the same structure and are both composed of a sliding groove and a sliding plate. The sliding groove of the first sliding assembly is opened on the top surface of the partition and extends to the edge of the partition. The sliding plate of the first sliding assembly is fixedly connected to the supporting plate of the upper bracket.
[0011] Furthermore, the slide groove of the second sliding assembly is provided on the bottom surface of the box body and extends to the edge thereof, and the slide plate of the second sliding assembly is fixedly connected to the bearing plate of the lower bracket.
[0012] Furthermore, the partition is fixedly connected to the box body, and an end of the partition away from the opening of the box body is an arc-shaped surface.
[0013] Furthermore, a thermometer is arranged outside the box and a detection end of the thermometer is located inside the box.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] During the initial heating of the interior of the box of the utility model, the electric heater and the infrared heater are turned on simultaneously. The infrared heater is used to dry and soften the core material, and the electric heater is mainly used to increase the temperature of the box. The two heaters work together to speed up the heating speed of the box and reduce the time required for drying and softening the core material. Moreover, when the temperature inside the box reaches the required range, the electric heater is turned off and only the infrared heater is used to dry the core material, thereby reducing energy consumption and lowering costs.
[0016] The upper bracket and the lower bracket of the utility model can be moved out of the box body through the first sliding assembly and the second sliding assembly respectively, so that it is convenient for personnel to sleeve the rolled core material on the outer periphery of the roller body of the upper bracket and to remove the core material from the roller body of the lower bracket.
[0017] The motor of the utility model can drive the roller of the lower bracket to rotate, so as to transport the core material from the upper bracket to the lower bracket. At this time, the infrared heater can dry the core material during the transportation process to ensure that the core material can be dried evenly to ensure the softening quality of the core material.
[0018] One end of the partition of the utility model is an arc surface, and the free end of the core material is connected to the lower bracket through the guidance of the arc surface. Since the arc surface is smooth, the core material can turn smoothly through the arc surface.
[0019] The thermometer of the utility model can detect the temperature inside the box, so that when the temperature inside the box rises to a required range, personnel can turn off the electric heater in time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0025] like Figure 1-3 As shown, a composite board infrared drying oven includes a box body 1 with an opening on one side, a box door 2 is also provided at the opening, an air outlet is provided on the top of the box body 1, an upper cavity 9 and a lower cavity 10 are separated by a partition 8 in the box body 1, an upper bracket 5 is slidably connected to the upper cavity 9 through a first sliding component 3, and a lower bracket 6 is slidably connected to the lower cavity 10 through a second sliding component 4, the upper bracket 5 and the lower bracket 6 have the same structure and are both composed of a bearing plate 601, a vertical plate 603 and a roller body 602, the roller body 602 is rotatably connected to the vertical plate 603 and the vertical plate 603 is fixedly connected to the bearing plate 601, infrared heaters 11 are respectively provided on the top of the upper cavity 9 and the top of the lower cavity 10, and electric heaters 12 are also installed in the upper cavity 9 and the lower cavity 10, and the type of the electric heater 12 is a resistance heater.
[0026] In this embodiment, if Figure 2As shown, the upper bracket 5 is first moved out of the box body 1 through the first sliding assembly 3, and then the rolled core material is sleeved on the roller body 602 of the upper bracket 5, and then the upper bracket 5 is moved into the box body 1 through the first sliding assembly 3, so that the rolled core material is moved into the upper cavity 9, and then the free end of the rolled core material is connected to the roller body 602 of the lower bracket 6 through the partition 8. Since the vertical plate 603 of the lower bracket 6 is also connected to the motor 7, the motor 7 is a high temperature resistant reduction motor, and the output shaft of the motor 7 is fixedly connected to the roller body 602 of the lower bracket 6, the motor 7 can drive the roller body 602 of the lower bracket 6. The body 602 rotates to transport the core material from the upper bracket 5 to the lower bracket 6. At the same time, the infrared heater 11 should be controlled to dry the core material to soften the core material. In addition, during the initial heating, the electric heater 12 should be turned on simultaneously to speed up the heating speed of the box body 1, reduce the time for the temperature of the box body 1 to rise to the required range, and avoid the heat on the core material from being transferred to other positions of the box body 1 to improve efficiency. When the internal temperature of the box body 1 reaches the required range, the electric heater 12 is turned off and only the infrared heater 11 is used to reduce energy consumption.
[0027] Among them, Figure 2 and Figure 3 As shown, the first sliding assembly 3 and the second sliding assembly 4 have the same structure and are both composed of a slide groove 401 and a slide plate 402. The slide groove 401 of the first sliding assembly 3 is opened on the top surface of the partition 8 and extends to the edge of the partition 8. The slide plate 402 of the first sliding assembly 3 is fixedly connected to the supporting plate 601 of the upper bracket 5. Therefore, when the slide plate 402 of the first sliding assembly 3 is disengaged from the matching slide groove 401, the upper bracket 5 can be moved out of the box body 1, and the slide groove 401 of the second sliding assembly 4 is opened on the bottom surface of the box body 1 and extends to its edge. The slide plate 402 of the second sliding assembly 4 is fixedly connected to the supporting plate 601 of the lower bracket 6. Therefore, when the slide plate 402 of the second sliding assembly 4 is moved out of the matching slide groove 401, the lower bracket 6 can be moved out of the box body 1, so that personnel can move the core material out of or into the box body 1.
[0028] Among them, Figure 2 and Figure 3 As shown, the partition 8 is fixedly connected to the box body 1 and the end of the partition 8 away from the opening of the box body 1 is an arc surface 801. The free end of the rolled core material is connected to the lower bracket 6 through the guidance of the arc surface 801. Since the arc surface 801 is smooth, the core material passes through more smoothly.
[0029] Among them, Figure 1 As shown, a thermometer 13 is provided on the outside of the box 1 and the detection end of the thermometer 13 is located inside the box 1. Therefore, the operator can know the temperature inside the box 1 through the thermometer 13, so that the operator can turn off the electric heater 12 in time.
[0030] Working principle: first, the upper bracket 5 is moved out of the box body 1 through the first sliding component 3, and then the rolled core material is sleeved on the roller body 602 of the upper bracket 5, and then the upper bracket 5 is moved into the box body 1 through the first sliding component 3, so that the rolled core material is moved into the upper cavity 9, and then the free end of the rolled core material is connected to the roller body 602 of the lower bracket 6 through the partition 8. Since the vertical plate 603 of the lower bracket 6 is also connected to the motor 7, the output shaft of the motor 7 is fixedly connected to the roller body 602 of the lower bracket 6. Therefore, the motor 7 can drive the roller body 602 of the lower bracket 6 to rotate, so as to transport the core material from the upper bracket 5 to the lower Bracket 6, at the same time, the infrared heater 11 should be controlled to work, so that it can dry the core material to achieve the purpose of softening the core material, and, during the initial heating, the electric heater 12 should be turned on simultaneously to speed up the heating rate of the box body 1 and improve efficiency. When the internal temperature of the box body 1 reaches the required range, the electric heater 12 is turned off, and only the infrared heater 11 is used to work, so as to reduce energy consumption. Next, when the drying operation of the core material is completed, the box door 2 is opened, and the lower bracket 6 is moved out of the box body 1 through the second sliding assembly 4, so that the dried and softened core material is moved out of the box body 1 to carry out the production operation of the next process.
