Embodiment 1

[0024] in such as figure 1 figure 2 In the shown embodiment 1, a through-type electromagnetic induction heating pipe structure includes a pipe body 1 and an induction heating coil 2 surrounding the periphery of the pipe body. The pipe body is arranged in a vertical state, and the inner cavity of the pipe body is horizontal. The cross-section is circular, suitable for circular workpieces, and the distance between the edge of the workpiece and the inner wall of the pipe is equal (see image 3); the body is provided with an induction heating coil, and there are 3 induction heating coils, which are arranged on the outer surface of the pipe body in sections, a buffer section 4 is provided between adjacent induction heating coils, and a buffer section of the pipe body is provided with There are two through holes 5, symmetrically arranged on both sides of the central axis of the pipe body, and a ventilation device 6 is arranged on the through hole, and the ventilation device is a f...

Embodiment 2

[0026] The cross-section of the inner cavity of the tube used in embodiment 2 is elliptical, which is compatible with the elliptical end workpiece, and the distance between the edge of the elliptical workpiece and the inner wall of the tube is equal (see Figure 4 ), the workpiece transmission device is two single-sided toothed synchronous belts, which are symmetrically arranged on the short side of the cross-section of the oval inner cavity of the pipe body. There is a partition 7 between them, and the tooth surface of the upward section of the single-sided toothed synchronous belt faces the center of the pipe body (see Figure 7 ), there are 4 induction heating coils, which are arranged on the outer surface of the pipe body, and the structure of the remaining pipe body parts is the same as that of embodiment 1.

Embodiment 3

[0028] Embodiment 3 The lumen cross-section of the pipe body is elliptical, and the length-to-short-side ratio of the lumen cross-section is greater than the length-to-short side ratio of the elliptical workpiece (see Figure 5 ), the workpiece transmission device is two double-sided toothed synchronous belts, which are symmetrically arranged in the direction of the short side of the inner cavity cross section. Separator, the structure of other pipe body parts is identical with embodiment 1.

[0029] When the through-type electromagnetic induction heating tube is working, the motor drives the synchronous belt arranged on the inner side of the tube body to move upward synchronously through the driving wheel 9, the driving wheel 10, and the driven wheel 11, and the iron sheet workpiece 8 such as the end cover passes through the lower part of the tube body. The inlet conveyor belt 12 at the port is transferred to the timing belt, and the workpiece is placed in the tooth grooves o...

Abstract

The invention discloses a through electromagnetic induction heating pipe structure, which comprises a pipe body and induction heating coils surrounding the periphery of the pipe body, wherein the pipe body is arranged vertically; the outside of the pipe body is provided with a plurality of induction heating coils; the inside of the pipe body is provided with a work piece transferring device; and both the pipe body and the work piece transferring device adopt non-magnetic heat-resisting materials. The through electromagnetic induction heating pipe structure effectively solves the problems of high energy consumption and long drying time of the prior heating and drying device for thin iron workpieces such as end covers and the like, and also solves the problems of easy adhesion among the workpieces and serious influence on the product quality in the prior heating and drying device for thin iron work pieces such as end covers and the like. The through electromagnetic induction heating pipe structure has the advantages of simple structure, low energy consumption, good drying effect and high product quality, and is worth of popularization and application.

Description

technical field [0001] The invention relates to an induction heating device for thin iron workpieces such as end caps, in particular to a through-type electromagnetic induction heating tube structure with good heating effect and uniform heating of workpieces. Background technique [0002] In the production of canned food, tea, food and other canned packaging products, it is necessary to apply sealant on the outer periphery of the metal sealing cover such as the bottom cover, top cover or easy-open cover of the can to ensure the sealing performance of the can after it is closed , and the metal sealing cover after applying the sealant needs to be heated and dried. Most of the traditional drying methods adopt the structural form of electric heating tube heating with workpiece conveying device or gas drying room heating. 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 ...
