Description

Technical Field

[0001] This utility model relates to the field of laminated stainless steel sheet technology, specifically to a heating device for the production of laminated stainless steel sheets. Background Technology

[0002] Laminated stainless steel sheet is a uniform steel sheet inside and out, which is widely used in industry, construction, aerospace and other fields. Its advantages include corrosion resistance, high temperature resistance and high tensile strength, making it suitable for various harsh working environments and demanding applications. During the production of laminated stainless steel sheet, the stainless steel sheet (substrate) needs to be heated, which requires the use of heating equipment.

[0003] To ensure the drying effect, the existing heating equipment for producing laminated stainless steel sheets uses a conveying device to transport the stainless steel sheet (substrate) into the heating chamber during the heating process. Multiple hot air nozzles in the heating chamber are used to heat and dry the stainless steel sheet. However, the following shortcomings exist in its use.

[0004] The fixed positions of multiple hot air nozzles cause the hot air to be too concentrated on the stainless steel surface, resulting in some parts of the steel plate being overheated while others are not fully heated, leading to uneven heating of the steel plate and affecting the heating effect. In view of this, this application proposes a heating device for the production of laminated stainless steel plates to solve the above-mentioned problems. Utility Model Content

[0038] Specifically, the hot air supply guide assembly includes a fixed box 4 fixedly installed on the right side of the top inner wall of the inverted U-shaped baffle 1. Multiple electric heating rods 402, which are air heating tubes, are fixedly installed between the front and rear inner walls of the fixed box 4. A fan 401 with an air outlet connected to the inside of the fixed box 4 is embedded and fixed on the right side. An air guide hood 403 is fixedly connected to the left side of the fixed box 4. A rectangular tube 404 is fixedly connected to the left side of the air guide hood 403.

[0040] Furthermore, the timed reminder component includes a timer switch 2 fixedly installed on the top left side of the inverted U-shaped baffle 1. The top of the timer switch 2 is fixed and electrically connected to an audible and visual warning light 201. The timer switch 2 and the audible and visual warning light 201 work together. Personnel can pre-set the activation time of the audible and visual warning light 201 according to the different pause heating time requirements of the stainless steel plate. When heating, personnel turn on the timer switch 2. When the pause heating time is reached, the timer switch 2 controls the audible and visual warning light 201 to turn on to warn personnel to continue the start and transport work, so as to achieve the effect of reminding personnel when the stainless steel plate reaches the set heating time.

[0041] The usage method of this embodiment is as follows: When using the laminating stainless steel plate production heating device, the stainless steel plate to be heated is placed on the steel belt conveyor 100. The steel belt conveyor 100 transports the stainless steel plate to be heated to the inverted U-shaped baffle 1. Then, the steel belt conveyor 100 is turned off, and the drive motor 5, fan 401 and electric heating rod 402 are started. The electric heating rod 402 heats the air entering the fixed box 4, and the fan 401 blows air into the fixed box 4. The heated air is then supplied to the distribution box 3 through the air guide hood 403, rectangular tube 404 and rectangular inner tube 405 in sequence, and then blown downwards through multiple nozzles 301 to heat the stainless steel plate to be heated below it. When the drive motor 5 is started, it drives the reciprocating screw 501 to rotate, reciprocating... The rotation of the lead screw 501 drives the slider 502 to slide back and forth on the two T-shaped guide rails. The slider 502 drives the diversion box 3 to slide back and forth on the two horizontal guide rods 503. The diversion box 3 drives the rectangular inner tube 405 to slide back and forth horizontally within the rectangular tube 404, performing horizontal guiding work. At the same time, the diversion box 3 drives multiple nozzles 301 to swing back and forth. By swinging multiple nozzles 301 back and forth, the phenomenon of uneven heating caused by each nozzle 301 blowing gas from a fixed point is avoided, thus avoiding the phenomenon of hot air being too concentrated on the stainless steel surface, improving the heating uniformity and heating effect. In addition, the cleaning brush 6 can brush and clean the top of the stainless steel plate when it is conveyed into the inverted U-shaped baffle 1, improving the cleaning effect of the top.

[0042] Personnel can pre-set the activation time of the audible and visual warning light 201 using timer switch 2 according to the different requirements for pausing heating of stainless steel plates. During heating, personnel turn on timer switch 2. When the pausing heating time is reached, timer switch 2 controls the audible and visual warning light 201 to turn on to remind personnel to continue the transportation work. This achieves the effect of reminding personnel when the stainless steel plate reaches the set heating time, avoiding the phenomenon of personnel neglecting to remember and leaving the plate idle for too long, resulting in waste.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
