Description

Technical Field

[0001] The utility model relates to the technical field of helmet processing, in particular to drying equipment for helmet spray processing. Background Art

[0002] A helmet is a head protection device. It is a hat worn by soldiers during training and combat. It is an indispensable tool for people to travel. It is mostly semicircular and mainly consists of three parts: the outer shell, the lining and the suspension device.

[0003] In the related art, a Chinese patent document with application number CN202223332132.3 proposes a drying device for helmet spraying, which heats the air in the heating box through a heating pipe. Under the action of a blower, the hot air enters the corrugated hose through the connecting pipe, and then enters the conducting pipe and is discharged through the conducting port. The discharged hot air realizes the drying of the sprayed helmet. At the same time, the rotation of the second motor drives the rotation of the cam, and the rotation of the cam drives the roller to move up, and the upward movement of the roller drives the sliding rod to move up, and the upward movement of the sliding rod drives the tooth plate to move up. At this time, the spring is compressed, and the upward movement of the tooth plate engages the second gear, so that the second gear realizes a certain angle of rotation, and the rotation of the second gear drives the rotation of the rotating shaft, and the rotation of the rotating shaft drives the conducting pipe to realize a certain angle of rotation. With the continuous rotation of the cam, the tooth plate reciprocates up and down, that is, the second gear is reciprocated by a certain angle, and the conducting pipe is reciprocated by a certain angle, that is, the contact area between the hot air and the sprayed helmet is increased, which is beneficial to the drying of the sprayed helmet.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the device directly draws air into the heating box for heating through a blower, resulting in a long heating time, and the particulate matter and some moisture contained in the device cannot be effectively filtered and will be directly sucked into the drying box, resulting in small protrusions on the surface of the helmet, affecting its appearance and causing subsequent product inspections to fail. In view of this, a drying device for helmet spray processing is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 A drying device for spraying helmets in this embodiment includes a drying box 1, a drying filter mechanism 2 is provided on the drying box 1, a reciprocating mechanism 3 is provided on the drying box 1, a rotating mechanism 4 is provided on the drying box 1, and a mounting assembly 5 is provided on the drying filter mechanism 2.

[0024] The drying and filtering mechanism 2 includes a heating box 202, a fan 204 and a filter box 208. The heating box 202, the fan 204 and the filter box 208 are fixedly installed on the upper end of the drying box 1 in sequence. A heating tube 203 is fixed in the heating box 202, and the air outlet end of the fan 204 is connected to one side of the heating box 202.

[0025] An air supply pipe 210 is connected between the air inlet end of the fan 204 and one side of the filter box 208. A circulation pipe 207 is fixed to the other side of the filter box 208. The other end of the circulation pipe 207 is located in the drying box 1. A rotatable drying pipe 206 is horizontally arranged in the heating box 202. A plurality of through holes for hot air discharge are provided at the lower end of the drying pipe 206. An air inlet pipe 201 is connected between one side of the drying pipe 206 and one end of the heating box 202.

[0026] The device starts the heating tube 203 and the fan 204, and the fan 204 transports air to the heating box 202, and then the heating tube 203 heats the air. The heated air enters the air inlet pipe 201 and the drying pipe 206, and then is discharged through the through hole to dry the helmet. Then, through the setting of the circulation pipe 207, the hot air in the drying box 1 is reintroduced into the heating box 202 to reduce the heating time.

[0027] A rectangular plate 209 is fixed in the filter box 208 , and a filter cartridge 211 is placed on the rectangular plate 209 . The filter cartridge 211 is used to filter the air.

[0028] At the same time, one end of the gas pipe 210 passes through the filter box 208 and is fixed to the inner top of the rectangular plate 209 , so as to facilitate the transmission of the filtered gas in the filter box 208 to the gas pipe 210 .

[0029] In addition, the filter cartridge 211 includes an inner filter screen 212 and an outer filter screen 213 of a cylindrical structure with an open bottom. The gas is filtered twice by the inner filter screen 212 and the outer filter screen 213. The top ends of the inner filter screen 212 and the outer filter screen 213 are connected by a circular plate 205. The outer filter screen 213 is used to filter large particles so that the large particles are directly filtered in the air intake pipe 201, and the inner filter screen 212 is used to filter fine dust.

[0030] A drying layer 214 is also provided between the inner filter 212 and the outer filter 213. The drying layer 214 is provided to dry the filtered gas to remove moisture from the gas and ensure that the gas source is dry and free of impurities. An air inlet is provided on the rectangular plate 209. The gas pipe 210, the air inlet and the filter cartridge 211 are on the same central axis. The drying layer 214 uses activated carbon adsorption particles. The diameter of the air inlet is slightly smaller than the diameter of the inner filter 212. The filter holes of the inner filter 212 are larger than the filter holes of the outer filter 213.

[0031] See also Figure 3 and Figure 5 The installation component 5 in this embodiment includes a positioning groove 503. The filter box 208 is provided with a positioning groove 503. The circular plate 205 is located in the positioning groove 503. Both ends of the circular plate 205 and the lower end of the positioning groove 503 are provided with threaded grooves 501. The threaded groove 501 is threadedly connected with a screw rod 502, and the screw rod 502 is connected with a nut 504.

[0032] The device places the circular plate 205 in the positioning groove 503, rotates the screw 502 so that the screw 502 passes through the thread groove 501 to be threadedly connected, and then rotates the nut 504 so that the nut 504 abuts against the circular plate 205, thereby fixing the circular plate 205.

[0033] The working principle of the above embodiment is:

[0034] By starting the heating tube 203 and the fan 204, the fan 204 transports air to the heating box 202, and then the heating tube 203 heats the air. The heated air enters the air inlet pipe 201 and the drying pipe 206, and then is discharged through the through hole to dry the helmet. Then, through the setting of the circulation pipe 207, the hot air in the drying box 1 is introduced into the circulation pipe 207.

[0035] The hot air is first filtered through the outer filter 213 to remove large particles of impurities, and then dried through the drying layer 214. The dried gas is finally filtered through the inner filter 212 to remove small particles of dust, and then enters the gas pipe 210. The fan 204 then draws the filtered gas into the heating box 202, thereby reducing the heating time.
