Description

Technical Field

[0001] The utility model relates to the field of rail transit cable production, in particular to a coating device for rail transit cable production. Background Art

[0002] In production and life, cables are particularly common in people's use, and their safety is also an important indicator in the process of selecting cables in people's daily life. Rail transit is one of the important means of transportation for contemporary people. In the selection process of cables used in the initial construction, the safety and service life of the cables are used as hard indicators. During the use of the cable, its external coating device serves as an external protective layer, which determines the service life and safety of the cable during use.

[0003] The outer layer of the existing cable is coated with a thermoplastic molded slurry. When the slurry is static for a long time, it is easy to precipitate and harden, which makes its coating effect on the cable poor. In addition, the cooling device of the cable usually adopts a condensation water structure. After working for a long time, the temperature of the condensation water increases, which easily leads to the deterioration of its condensation effect. Utility Model Content

[0009] Preferably, a first spring is installed symmetrically on the inner side wall of the limiting sleeve, and an arc plate is installed on the other end of the first spring.

[0010] Technical effects and advantages of the utility model:

[0011] 1. The utility model adopts the first motor structure, and the first motor drives the stirring rod to stir the slurry to avoid the slurry settling after being stationary for a long time, thereby failing to achieve the coating effect on the cable surface.

[0012] 2. The utility model adopts a water cavity structure to quickly cool down the outer slurry layer of the cable through condensed water to improve its molding rate. At the same time, a temperature sensor structure is adopted to avoid the water temperature in the second ring cavity from rising after long-term cooling treatment, which will not have the cooling effect on the cable.

When working, the slurry enters the slurry pump 2 through the feed pipe after thermal treatment, and the cable is arranged in the first annular cavity 14. The valve on the first connecting pipe 15 is opened, and the slurry enters the first annular cavity 14 through the first connecting pipe 15. The cable surface is sprayed by the nozzle 16. In order to avoid the slurry settling due to long-term static state, so as to achieve the failure of coating the cable surface, the first motor 11 is started to drive the annular frame 12 to rotate, and the annular frame 12 drives the stirring rod 13 to rotate, so as to stir the slurry to prevent it from static hardening.

[0020] A water chamber 17 is arranged in front of the slurry pump 2, and a second annular chamber 18 is arranged on the right side of the water chamber 17. The water chamber 17 and the second annular chamber 18 are connected by a second connecting pipe 19. When working, the water chamber 17 is filled with condensed water, and the water in the water chamber 17 is transported to the first annular chamber 14 through the second connecting pipe 19. The cable passes through the inner end of the first annular chamber 14, and the condensed water in the second annular chamber 18 quickly cools down the outer slurry layer of the cable, thereby increasing its forming rate.

[0021] A water pump 21 is installed on the upper end surface of the workbench 1, and the water pump 21 is connected to the water cavity 17 and the second annular cavity 18 through a connecting pipe. When working, after a long period of cooling treatment, the water temperature in the second annular cavity 18 will increase, and at this time, it will not have a cooling effect on the cable. At this time, the water pump 21 is turned on, and the water in the second annular cavity 18 enters the water cavity 17 through the connecting pipe, thereby realizing the recycling of water.

[0022] A plurality of temperature sensors 22 are installed along the circumferential direction of the inner wall of the second annular cavity 18 .

[0024] The first spring 25 is symmetrically installed on the inner wall of the limiting sleeve 24, and an arc plate 26 is installed on the other end of the first spring 25.

The electric slider 23 is started to drive the cable to move forward, so that the entire cable is clad.

[0025] During specific operation, one end of the cable is fixed in the limit sleeve 24, and the first spring 25 drives the arc plate 26 to move toward the inner end to fix the cable.

The electric slider 23 is started to drive the cable forward, thereby covering the entire cable.
