DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0027] like Figure 1-4 As shown, an embodiment of the present application discloses a tunnel-type infrared heating furnace, including a frame 10, a linear module 11, a tray frame 20 and a heating assembly 30, wherein two linear modules 11 are respectively arranged on both sides of the frame 10 and arranged along its length direction, and the linear module 11 runs through the feeding area, the heating area and the discharging area; the tray frame 20 is arranged above the linear module 11, and the bottom of the tray frame 20 is respectively connected to the sliders of the two linear modules 11, and the material plate is carried by the tray frame 20; the heating assembly 30 is arranged in the middle section of the frame 10 for heating the material plate; the linear module 11 pulls the tray frame 20 to move smoothly between the feeding area, the heating area and the discharging area, thereby ensuring the stability of the material plate in the transmission between the various areas.

[0028] Specifically, the input shafts of the two linear modules 11 are connected together through a driving rod 14, so that the input shafts of the two linear modules 11 can rotate synchronously. A driving motor 15 is provided on the frame 10, and the output shaft of the driving motor 15 is connected to the input shaft of one of the linear modules 11, so that the driving motor 15 can drive the two linear modules 11 to move synchronously, thereby ensuring the stability of the movement of the tray frame 20.

[0029] A steel mesh 22 woven by steel wire ropes 21 is arranged in the tray frame 20, and the material plate is placed on the steel mesh 22, so that the heat component can heat the upper and lower sides of the material plate to avoid uneven heating. When setting, a fixing seat 23 is arranged on the adjacent two sides of the tray frame 20, and an adjustment seat 24 is arranged on the side of the tray frame 20 relative to the fixing seat 23. A plurality of threaded holes 25 are arranged at intervals along the length direction of the adjustment seat 24, and the hole core of the threaded hole 25 is located in the horizontal direction and perpendicular to the length direction of the adjustment seat 24. A stud 26 is spirally arranged in the threaded hole 25, and a circular hole is arranged in the stud 26 with the same core. An annular groove is also opened on the wall of the circular hole, and a circular plate is rotatably arranged in the annular groove. One end of the steel wire rope 21 is connected to the fixing seat 23, and the other end extends into the circular hole and is fixedly connected to the circular plate, so that the steel wire rope 21 and the stud 26 can rotate relative to each other. There is a cross groove on the outer surface of the stud 26. When the tension of the wire rope 21 needs to be adjusted, the stud 26 is rotated by a screwdriver so that the stud 26 drives one end of the wire rope 21 to move outward, so that the wire rope 21 is tightened and has better bearing capacity. At the same time, the wire rope 21 and the stud 26 are rotatably connected to prevent the rotation of the stud 26 from twisting the wire rope 21, thereby causing uneven stress distribution inside the wire rope 21.

[0030] In the specific configuration, the heating assembly 30 includes a heating plate 31 and an infrared heater. Two heating plates 31 are respectively arranged on the upper and lower sides of the tray. There are several infrared heaters, which are arranged on the plate surface of the heating plate 31 adjacent to the tray frame 20, so as to heat the upper and lower sides of the material plate, ensuring that the material plate is fully heated. The infrared heater can also be controlled by partition according to the size of the material plate. When the material plate is small, only the infrared heating lamp of the corresponding area needs to be turned on to reduce energy consumption. Several through holes are arranged at intervals on the heating plate 31, and a fan 32 is arranged in the through hole. Air is blown outward by the fan 32 to avoid excessive temperature in the heating assembly 30.

[0031] The two heating plates 31 are all surrounded by a panel 33 extending toward the middle, and the panel 33 prevents heat loss from the heating plates 31. The frame 10 around the heating assembly 30 is provided with a baffle 12, and the inner surface of the baffle 12 is provided with a heat insulation board 13, which isolates heat and effectively reduces the temperature of the baffle 12, thereby avoiding safety hazards caused by overheating of the baffle 12.

[0032] The use principle of a tunnel-type infrared heating furnace in this embodiment is as follows: the material sheet is placed on the wire mesh 22 of the tray frame 20 by a robotic arm, the drive motor 15 is started to drive the two linear modules 11 to move synchronously to move the tray frame 20 to the middle of the frame 10, and then the heating component 30 is started. The heating component 30 heats the upper and lower surfaces of the material sheet at the same time to ensure uniform heating. After the heating is completed, the linear component moves the tray frame 20 to the discharge area, and the robotic arm removes the material sheet and transports it to the next step. After the material sheet is removed, the linear module 11 drives the tray frame 20 to move to the feeding area to complete a process. The linear module 11 runs through the feeding area, the heating area, and the discharge area to ensure the stability of the material sheet in the transmission between the various areas.

[0033] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
