[0002] Infrared heating is a heating method that relies on infrared radiation to transfer heat, directly heating objects instead of the surrounding air. It features direct heating (no air as a medium), high thermal efficiency, fast response rate, high temperature control accuracy, focused heating (through the design and installation of reflectors, over 90% of the energy can be concentrated within a 30° divergence angle), non-contact heating (reducing dust and other pollution from hot air), and good wind resistance (in a wind speed of 5 m / s, the effective heat output of an infrared heater decreases by only 15%, while the efficiency of a hot air furnace decreases by more than 40%).

[0016] Example 1 like Figure 1-5 As shown, an adjustable handheld high-efficiency infrared heating device for rapid curing is provided. A control system 5 on the support plate 1 is used to accelerate the curing degree of the paint film. The control system 5 includes a temperature controller 501 on the upper surface of the support plate 1 and an infrared radiation plate 502 on the lower surface of the support plate 1. The temperature controller 501 and the infrared radiation plate 502 are connected by a signal. A lead screw is rotatably provided at both ends of the support plate 1 in the vertical direction. A light-concentrating sheet 7 is provided on both sides of the lower surface of the support plate 1. When the lead screw rotates along the support plate 1, it is used to unfold the light-concentrating sheet 7. The corresponding surfaces of the two light-concentrating sheets 7 are provided with infrared reflective coating. The infrared reflective coating is used to concentrate the light source generated by the infrared radiation plate 502.

[0017] Furthermore, the temperature controller 501 fixed on the upper surface of the support plate 1 is equipped with a display panel and a temperature sensor. The temperature sensor signal is connected to the infrared radiation plate 502 and feeds back the temperature of the infrared radiation plate 502 to the display panel. The display panel can adjust the temperature at which the paint film needs to be cured by the infrared radiation plate 502, and the display panel can turn off the infrared radiation plate 502 at any time. The focusing sheet 7 is folded into a fan shape when not unfolded, and becomes a thin sheet when unfolded. Moreover, the focusing sheet 7 is tilted after unfolding, which is beneficial for focusing the light emitted by the infrared radiation plate 502 onto the position where the paint film is sprayed. The lead screw is vertically movable on both sides of the support plate 1, and the lead screw unfolds or folds the focusing sheet 7 during rotation. The focusing sheet 7 is made of a flexible or lightweight rigid substrate (such as aluminum foil composite film, polyester film, or stainless steel sheet), and its surface is uniformly coated with a layer of high-reflectivity infrared reflective coating, which has high reflectivity for mid-wave or long-wave infrared light.

[0018] The upper surface of the support plate 1 is also provided with a handle 101, and the two ends of the support plate 1 are provided with connecting components 13, which are rotatably connected to the first rotating plate 2 and the second rotating plate 3 respectively.

[0019] Furthermore, the support plate 1 is fixed with a handle 101 for easy handling by staff. The two ends of the support plate 1 are rotatably connected to the first rotating plate 2 and the second rotating plate 3 via a connecting assembly 13, so that the first rotating plate 2 and the second rotating plate 3 can be flipped with the connecting assembly 13 and can be folded for easy storage. The support plate 1, the first rotating plate 2, and the second rotating plate 3 are made of metal or plastic materials with low thermal conductivity to avoid accidental injury to staff due to the high thermal conductivity of the materials themselves.

[0020] The support plate 1 is fixedly provided with fixing components 4 on both sides, and the fixing components 4 are detachably connected to the first rotating plate 2 and the second rotating plate 3.

[0021] Furthermore, fixing components 4 are fixedly installed at intervals on both sides of the support plate 1. The fixing components 4 can fix the first rotating plate 2 and the second rotating plate 3 to the support plate 1 on the same plane. When the first rotating plate 2 and the second rotating plate 3 are flipped to the same horizontal plane as the support plate 1, the fixing components 4 fix the first rotating plate 2 and the second rotating plate 3 to the support plate 1. The fixing components 4 are detachably connected to the first rotating plate 2 and the second rotating plate 3, and facilitate the loosening of the first rotating plate 2 and the second rotating plate 3 and folding through the connecting components 13.

[0022] The lead screw includes a first lead screw 9 disposed on the first rotating plate 2 and a second lead screw 10 disposed on the second rotating plate 3, with the first lead screw 9 and the second lead screw 10 being staggered.

[0023] Furthermore, the lead screw includes a first lead screw 9 and a second lead screw 10. The first lead screw 9 is movably mounted on the first lead screw 9, and the second lead screw 10 is movably mounted on the second rotating plate 3. The first lead screw 9 and the second lead screw 10 are staggered to facilitate the storage of the first lead screw 9 and the second lead screw 10.

[0024] The connecting assembly 13 includes a connecting rod 1302 rotatably connected to two sets of adapter shafts 1301, and the two sets of adapter shafts 1301 are concentrically arranged. One set of adapter shafts 1301 is fixed to both ends of the support plate 1, and the other set of adapter shafts 1301 is fixed to the first rotating plate 2 and the second rotating plate 3 respectively.

[0025] Furthermore, the connecting assembly 13 includes a transition shaft 1301 and a connecting rod 1302. The transition shaft 1301 is provided in two sets, which are concentrically arranged. Each set of connecting shafts 1301 has multiple shafts spaced apart. The transition shaft 1301 is a hollow circular tube. One set of transition shafts 1301 is fixedly connected to both ends of the support plate 1, and the other set of transition shafts 1301 is fixedly connected to the first rotating plate 2 and the second rotating plate 3 respectively. There are two connecting rods 1302, which are movably sleeved on the two sets of transition shafts 1301 respectively, so that the first rotating plate 2 and the second rotating plate 3 can be flipped on the support plate 1, and the first lead screw 9 and the second lead screw 10 can be flipped to be parallel to the support plate 1 through the two rotating plates respectively.

[0026] The fixing component 4 includes a fixing plate 401, a tightening screw 402, and a tightening nut 403. The fixing plate 401 is fixedly connected to both sides of the support plate 1 on one side, and detachably connected to the first rotating plate 2 and the second rotating plate 3 on the other side. The tightening screw 402 is provided with through holes on the first rotating plate 2, the second rotating plate 3, and the fixing plate 401 respectively. The tightening nut 403 is threaded to both ends of the tightening screw 402. When the tightening nut 403 rotates on the tightening screw 402, it holds the fixing plate 401 against it, so as to fix the first rotating plate 2 and the second rotating plate 3 to the support plate 1.

[0027] Furthermore, the fixing component 4 includes a fixing plate 401, a tightening screw 402, and a tightening nut 403. The fixing plate 401 has two sets, with two plates in each set, respectively located on both sides of the support plate 1. One side of the fixing plate 401 is fixedly connected to the support plate 1, and the other side is detachably connected to the first rotating plate 2 and the second rotating plate 3. The tightening screw 402 has threads and moves through the through holes provided in the first rotating plate 2, the second rotating plate 3, and the fixing plate 401. Because the fixing plate 401 is fixedly connected to the support plate 1, when the tightening nut 403 is threaded onto both ends of the tightening screw 402, the tightening nut 403 can hold the fixing plate 401 against the first rotating plate 2 and the second rotating plate 3 respectively, so that the first rotating plate 2 and the second rotating plate 3 are parallel and fixed to the support plate 1. At this time, the focusing sheet 7 connected to the first rotating plate 2 and the second rotating plate 3 is unfolded.

[0028] The first rotating plate 2 and the second rotating plate 3 are respectively inclined at the ends away from the support plate 1 and are provided with adjusting nuts 8. The first lead screw 9 and the second lead screw 10 are respectively threaded to the adjusting nuts 8.

[0029] Furthermore, one end of the first rotating plate 2 and the second rotating plate 3 is fixedly connected with an adjusting nut 8 at an angle, and the adjusting nut 8 is located at the end away from the support plate 1. The first lead screw 9 and the second lead screw 10 are respectively threaded onto the adjusting nut 8. When the first lead screw 9 and the second lead screw 10 rotate in the adjusting nut 8, they can move up and down and realize the unfolding and folding of the light-concentrating sheet 7.

[0030] The light-concentrating sheet 7 is fixedly connected to the lower surface of the first rotating plate 2 and the second rotating plate 3 respectively.

[0031] Furthermore, the light-concentrating sheet 7 is fan-shaped and foldable. The light-concentrating sheet 7 is fixedly connected to the lower surface of the first rotating plate 2 and the second rotating plate 3 respectively, and can be flipped and stored along with the first rotating plate 2 and the second rotating plate 3.

[0032] Several connecting rings 11 are spaced apart on the back of the two light-concentrating sheets 7, and an adjusting bearing 12 is provided at the lower end of each light-concentrating sheet 7. One end of the first lead screw 9 and the second lead screw 10 respectively passes through the connecting rings 11 and is fixedly sleeved on the adjusting bearing 12.

[0033] Furthermore, the fixed connecting rings 11 of the light-concentrating sheet 7 are used to pass through the first lead screw 9 and the second lead screw 10 respectively, so as to avoid the two light-concentrating sheets 7 being unsupported when unfolded. The lower end of the light-concentrating sheet 7 is fixedly installed with an adjusting bearing 12. The first lead screw 9 and the second lead screw 10 are threaded to the adjusting nut 8 and pass through the connecting rings 11 respectively, and are fixedly sleeved in the middle of the adjusting bearing 12. When the first lead screw 9 and the second lead screw 10 rotate, the adjusting bearing 12 can increase the sliding of the rotation. The rotation of the first lead screw 9 and the second lead screw 10 can realize the vertical translation and realize the unfolding and folding of the light-concentrating sheet 7.

[0034] The other end of the first lead screw 9 and the second lead screw 10 is provided with a handle 910.

[0035] Furthermore, the handle 910 is made of heat-insulating plastic material. The handle 910 is installed on the first lead screw 9 and the second lead screw 10, which facilitates the operator to rotate the first lead screw 9 and the second lead screw 10.

[0036] Example 2 The support plate 1 serves as the main support for the entire structure. When the fixing component 4 is released, the first rotating plate 2 and the second rotating plate 3 can flip up and down along both ends of the support plate 1, thus achieving the folding of the entire structure. The control system 5 is installed on the support plate 1, and the temperature controller 501 in the control system 5 can control the temperature of the infrared radiation plate 502. The first lead screw 9 and the second lead screw 10 are respectively mounted on the rotating plate through the adjusting nut 8, and the first lead screw 9 and the second lead screw 10 can rotate on the adjusting nut 8. When the first lead screw 9 and the second lead screw 10 rotate, the light-concentrating sheet 7 is unfolded and straightened. The corresponding surface of the light-concentrating sheet 7 is coated with infrared reflective paint, which facilitates the reflection of the light emitted by the infrared radiation plate 502 and focuses the light onto the paint that needs to be dried.

[0037] The upper surface of the support plate 1 is provided with a power outlet, which facilitates the connection of the control system 5 to a power source. A rechargeable lithium battery can also be installed on the support plate 1 to handle special situations. When the first rotating plate 2 and the second rotating plate 3 need to be flipped upwards, the first lead screw 9 and the second lead screw 10 are rotated to retract the focusing sheet 7, and then the first rotating plate 2 and the second rotating plate 3 are flipped. When the first rotating plate 2 and the second rotating plate 3 need to be flipped downwards, the infrared radiation plate 502 needs to be cooled down, and the focusing sheet 7 does not need to be folded. The first rotating plate 2 and the second rotating plate 3 can be flipped downwards directly, and the first lead screw 9 and the second lead screw 10 flip and fold along with the rotating plates.

[0038] In summary, the implementation principle of the embodiment is as follows: First, the first rotating plate 2 and the second rotating plate 3 are flipped to be parallel along both ends of the support plate 1. The first rotating plate 2 and the second rotating plate 3 are locked on the support plate 1 by the fixing components. Then, the first lead screw 9 and the second lead screw 10 are rotated to unfold and straighten the light-concentrating sheet 7. Finally, the control system 5 is powered on, and the infrared radiation plate 502 is set to a suitable temperature by the temperature controller 501. Wait for the infrared radiation plate 502 to preheat. After preheating, the operator holds the handle 101 and moves this structure to the coating area that needs to be dried.
