[0025] The bracket 110 is used to install the first cylinder 120 and the second cylinder 130 to ensure the stability of the first cylinder 120 and the second cylinder 130. The first cylinder 120 is fixed on the bracket 110, and a feeding pipe 121 is fixed at one end to communicate with the inner cavity of the first cylinder 120 to facilitate the cable to be fed into the inner cavity of the first cylinder 120, and a connecting pipe 122 is provided at the other end to extend into the inner cavity of the second cylinder 130 to facilitate the cable to be fed into the second cylinder 130 after the surface is initially cured.

[0026] The spraying member 140 is used to spray hot air evenly to preliminarily dry the melted plastic on the surface of the cable, and includes a rectangular empty tube 141 fixed on the inner wall of the first cylinder 120 and a nozzle 142 fixed in an array on the rectangular empty tube 141 and connected to the inner cavity of the rectangular empty tube 141. The rectangular empty tube 141 is used to install the nozzle 142 and send hot air into the nozzle 142. The nozzle 142 is used to spray hot air.

[0027] The transmission component 150 is used to deliver the hot air into the ejection component 140. It includes an annular empty pipe 151 sleeved on the outside of the first cylinder 120 and a branch pipe 152 fixed on the inside of the annular empty pipe 151 in an annular array. One end of the branch pipe 152 is connected to the annular empty pipe 151 and the other end is connected to the rectangular empty pipe 141, so that the hot air in the annular empty pipe 151 can enter the rectangular empty pipe 141 through the branch pipe 152.

[0028] The hot air component 160 is used to generate hot air, and includes a shell 161 fixed to the outside of the first cylinder 120 and connected to the annular empty pipe 151, a high-speed fan 162 installed on the inner wall of the shell 161, an electric heating wire 163 installed on the inner wall of the shell 161, and a filter 164 fixed on one side of the shell 161.

[0030] The driving member 190 includes a motor 191 installed on a side bracket 110 and a gear 192 fixedly sleeved on the shaft of the motor 191. The gear 192 is meshed with the gear ring 180. When the motor 191 rotates, it drives the gear 192 to rotate. The rotation of the gear 192 drives the gear ring 180 to rotate. The rotation of the gear ring 180 drives the second cylinder 130 to rotate. The rotation of the second cylinder 130 drives the ultraviolet lamp 170 to rotate. When the cable passes through the second cylinder 130, the rotating ultraviolet lamp 170 can irradiate the surface of the cable in all directions to ensure the uniformity of ultraviolet light curing.

[0031] The working principle and use process of the utility model are as follows: when in use, the cable with melted plastic attached to the surface is placed in the first cylinder 120, at which time the motor 191 is started to suck the outside air into the shell 161 and accelerate it into the annular empty pipe 151, and at the same time the electric heating wire 163 is started to heat the sucked air to make it a high-temperature airflow, and the high-temperature airflow enters the annular empty pipe 151 and then enters the rectangular empty pipe 141 through the branch pipe 152, and is sprayed outward through the nozzle 142 to preliminarily solidify the plastic on the surface of the cable, so that After initial condensation, the cable with a preliminary solidified surface enters the second cylinder 130, and the ultraviolet lamp 170 is started to solidify the plastic protective layer on the cable surface. At the same time, the motor 191 is started to drive the gear 192 to rotate, and the rotation of the gear 192 drives the gear ring 180 to rotate, and the rotation of the gear ring 180 drives the second cylinder 130 to rotate. The rotation of the second cylinder 130 drives the ultraviolet lamp 170 on its inner wall to rotate, so as to ensure the uniformity of ultraviolet light irradiation and improve the curing effect. The cable with the surface solidified is sent out from one side of the second cylinder 130.
