Embodiment 1

[0026] in such as figure 1 In the shown embodiment 1, a through-type electromagnetic induction heating drying furnace includes a frame 1, an electromagnetic heating pipeline 2 and a workpiece conveying device. The electromagnetic heating pipeline is vertically arranged, and the inner cavity cross section of the electromagnetic heating pipeline is It is round and suitable for round workpieces, and the distance between the edge of the workpiece and the inner wall of the electromagnetic heating pipe is equal (see Figure 5 ). The electromagnetic heating pipeline includes a pipe body 3 and an induction heating coil 4 arranged around the pipe body. There are three induction heating coils, which are arranged in sections on the outer surface of the pipe body. A buffer section 5 is arranged between adjacent induction heating coils. The buffer section on the upper side of the body is symmetrically provided with a through hole 6, and the through hole is provided with a ventilation devi...

Embodiment 2

[0028] The workpiece conveyor belt adopted in embodiment 2 is a double-sided toothed synchronous belt, and the inner cavity cross section of the electromagnetic heating pipeline is non-dome-shaped, which is suitable for the non-dome-shaped workpiece, and the distance between the edge of the workpiece and the inner wall of the electromagnetic heating pipeline is equal, so The timing belt described above is set in the direction of the short side of the non-circular cover (see Figure 6 ). Compared with Example 1, there is no reversing wheel, and four limit wheels are arranged at the upper and lower ends of the electromagnetic heating pipeline. The driven wheel has the characteristic of unidirectional rotation and has a tensioning effect. All the other are identical with embodiment 1.

Embodiment 3

[0030] The synchronous belt used in embodiment 3 is a double-sided toothed synchronous belt, and the synchronous belt is arranged around the side wall of the electromagnetic heating pipeline. The inner cavity cross section of the electromagnetic heating pipeline is non-circular-shaped, and the ratio of the length of the inner cavity cross-section non-circular cap is Greater than the ratio of the long and short sides of the non-circular-shaped workpiece, the conveyor belt is arranged on the short-side direction of the non-circular cap (see Figure 7 ). Compared with embodiment 2, no limit wheel and liner are provided, the driven wheel doubles as a one-way wheel, and the rest are the same as embodiment 2.

[0031] When the through-type electromagnetic induction heating drying furnace is working, the motor drives the synchronous belts arranged on both sides of the electromagnetic heating pipeline to move upward synchronously through the driving wheel and the driving wheel, and th...

Abstract

The invention discloses a through electromagnetic induction heating and drying furnace, which comprises a stander, an electromagnetic heating pipe arranged vertically and a workpiece conveying device, wherein the electromagnetic heating pipe comprises a pipe body and induction heating coils arranged around the pipe body; the induction heating coils are arranged on the pipe body by section; a buffer section is arranged between the adjacent induction heating coils; at least one buffer section of the pipe body is provided with a through hole and a ventilating device; the workpiece conveying device comprises a motor, a transmission mechanism and a workpiece conveyor belt; the motor drives the workpiece conveyor belt through the transmission mechanism; and both the pipe body and the workpiece conveyor belt are made of non-conductive heat-resisting materials. The through electromagnetic induction heating and drying furnace effectively solves the problems that the prior heating and drying device for end covers and other iron sheet workpieces has high energy consumption and long drying time, workpieces are easily mutually stuck and the product quality is seriously influenced. The through electromagnetic induction heating and drying furnace has the advantages of simple structure, low energy consumption, good drying effect and high product quality, and is worthy of popularization and use.

Description

technical field [0001] The invention relates to a heating and drying device, in particular to a through-type electromagnetic induction heating and drying furnace with high work efficiency and low energy consumption. Background technique [0002] In the production of cans, tea, food and other can packaging products, during the production process of the cans, it is necessary to apply anti-corrosion glue on the end caps at both ends of the cans to ensure the anti-rust performance of the processed end caps, while applying anti-corrosion After gluing, the end caps need to be heated and dried. Traditional end caps and other thin iron workpieces are mostly dried by electric heating tubes with workpiece conveyors or gas-fired ovens. The disadvantage of this type of heating and drying process is high energy consumption and long drying time. In addition, because the anticorrosion glue is an adhesive substance, the traditional drying method still has the problem that the end caps are ...
