The utility model does not improve the structure of the high-frequency induction heater. At the same time, this is not the focus of the improvement of the utility model. Therefore, the structure of the high-frequency heating mechanism is no longer repeated; at the same time, in order to improve the drying efficiency, the hot air duct is located directly below the cotton swab head, and the hot air flowing out of the hot air hole blows hot air directly to the cotton swab head to dry the cotton swab head; in addition, it should be noted that the cotton swab drying device of the utility model can be used in conjunction with other equipment in the cotton swab production process, such as cotton swab disinfection, cotton swab packaging, etc., to form a cotton swab production line, and the cotton swabs are transported by the cotton swab conveying mechanism to perform disinfection, drying, packaging and other processes in sequence to complete the cotton swab production.

[0027] In one of the embodiments, a lower insulation mechanism 5 is provided on the lower side of the cotton swab conveying mechanism, and an upper insulation mechanism 4 is provided on the upper side of the cotton swab conveying mechanism; the lower side of the hot air pipe 9 is embedded in the lower insulation mechanism 5. By providing the lower insulation mechanism and the upper insulation mechanism, not only can the heat loss be reduced, but also burns caused by excessive temperature on the outer surface of the equipment can be avoided.

[0028] In one embodiment, the lower insulation mechanism 5 and the upper insulation mechanism 4 are both L-shaped as a whole. The lower insulation mechanism 5 and the upper insulation structure are relatively arranged to form a rectangular channel. The cotton swab conveying mechanism passes through the rectangular channel and is dried in the rectangular channel.

[0029] In one embodiment, the lower heat insulation mechanism 5 is fixedly mounted on the frame 1, and the upper heat insulation mechanism 4 is hinged to the frame 1. During use, the upper heat insulation mechanism can be opened for easy maintenance.

[0030] In one of the embodiments, a cotton swab pressing plate 6 is provided above the cotton swab conveying mechanism, and the cotton swab pressing plate 6 is connected to the vertical part of the lower heat insulation mechanism 5 through a plurality of connecting columns 7. The upper heat insulation mechanism 4 is provided with a receiving groove on the upper side corresponding to the cotton swab pressing plate 6. The cotton swab is pressed by the cotton swab pressing plate to prevent one end of the cotton swab from being blown up by hot air and falling from the cotton swab conveying mechanism. In order to improve stability, the cotton swab pressing plate is directly opposite to the middle of the cotton swab rod. In addition, a precision-milled steel ingot bar can be used as the cotton swab pressing plate. In order to improve the stability of the cotton swab pressing plate installation and avoid deformation, a thick wall panel can be provided on the frame, and one end of each connecting column is installed on the thick wall panel.

[0031] In one embodiment, a hot air gathering protective cover 8 is provided above the hot air pipe 9. The hot air gathering protective cover gathers the hot air near the cotton swab head to improve the hot air drying efficiency.

[0033] In one embodiment, the lower insulation mechanism 5 and the upper insulation mechanism 4 both include an insulation board arranged on the surface and insulation cotton arranged on the inner side. The lateral part of the upper insulation mechanism 4 is hinged to the frame 1. Specifically, the insulation board can be a mica insulation board, and insulation is performed by the insulation cotton and the insulation board.

[0034] In one embodiment, the vertical part of the upper heat insulation mechanism 4 is installed with a first heat insulation strip 11. When the upper heat insulation mechanism 4 is buckled with the lower heat insulation mechanism 5, the first heat insulation strip 11 abuts against the lower heat insulation mechanism 5; a second heat insulation strip 12 is arranged between the hot air duct 9 and the lower heat insulation mechanism 5. Specifically, the heat insulation strip can be a silicone strip, which plays a role of sealing and heat insulation; the first heat insulation strip includes an arc-shaped strip, the lower surface of the arc-shaped strip is an arc surface, the upper surface is a plane, an L-connecting part is arranged on the upper side of the arc-shaped strip, a snap-fitting gap is reserved on the upper heat insulation mechanism, the horizontal part of the L-connecting part can extend into the gap, the vertical part of the L-connecting part connects the upper surface of the arc-shaped strip, and the arc-shaped strip is provided with a cavity. When the first heat insulation strip 11 abuts against the lower heat insulation mechanism 5, the lower end of the first heat insulation strip is slightly deformed and pressed against the lower heat insulation mechanism, so that the sealing and heat insulation effect is better.

[0035] In one embodiment, the cotton swab conveying mechanism includes a transmission chain and a cotton swab bracket 15 arranged on both sides of the transmission chain. The upper surface of the cotton swab bracket 15 is evenly provided with a plurality of saw teeth, and the groove between two adjacent saw teeth is used to place the cotton swab. Specifically, the cotton swab conveying mechanism can be used to feed the cotton swab disinfection, drying, packaging and other processes of the cotton swab production line.

A rotatable roller is provided on each link 14 of the transmission chain, and the roller is tangent to the upper surface of the guide convex strip. Specifically, the transmission chain adopts a roller chain, and the roller rolls along the guide convex strip during the drying process.

[0037] The above embodiments can be combined with each other.

[0038] During use, the transmission chain carries the cotton swab through the rectangular channel for drying. A return air port is provided at the end of the rectangular channel, and the circulating fan draws air with residual heat into the high-frequency heating mechanism, which enters the hot air duct after being heated by the high-frequency heating mechanism. The utility model adopts a high-frequency heating mechanism instead of a resistance tube for heating, which has fast heating and high efficiency. Heat insulation mechanisms are respectively provided on the upper and lower sides of the hot air duct to avoid burns and reduce energy consumption. The transmission chain is supported by a chain guide to ensure the stability of the cotton swab transportation. The chain link rollers of the transmission chain are tangent to the guide convex strips of the chain guide. During the transportation process, the chain link rollers roll along the guide convex strips. Compared with sliding, the rolling friction is smaller, which reduces the wear of the transmission chain due to friction and extends the service life. A cotton swab pressing plate is provided to press on the top of the cotton swab to prevent the cotton swab from falling.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
