In the production process of photovoltaic cables, in order to ensure the tight wrapping between the sheath and the conductor, the cable conductor needs to be preheated. Traditional preheating devices have many shortcomings, such as the easy adhesion of foreign particles on the surface of the cable conductor and poor preheating effect. These problems will affect the production quality and service life of photovoltaic cables.

[0023] Among them, a door panel 16 is installed through a hinge just below the control panel 2 and at the port of the box body 1, and a handle 17 is provided on the outer wall of the door panel 16.

[0024] The method for using the device of the present invention comprises the following steps: Operation step 1: When the switch of the control panel is turned on, the control panel controls the driving motor to operate, and then the driving shaft of the driving motor drives the reel to operate, and the reel drives the cable to move laterally. At the same time, the control panel controls the operation of the heating rod, and the heating rod preheats the cable on one side. The control panel controls the operation of the fan filter, and then the fan filter generates airflow to blow the heating rod, and the device generates hot air to preheat the cable inside the preheating cavity.

[0025] Operation step two: When the cable moves to the cleaning chamber, the conical coil spring inside the cleaning chamber is sleeved on the cable, so that the conical coil spring scrapes the outer wall of the cable, thereby scraping off large pieces of adhesion on the surface of the cable. At the same time, the control panel controls the high-pressure atomizing nozzle to open, and the high-pressure atomizing nozzle generates high-pressure mist to clean the floating dust on the surface of the cable. The conical coil spring is just sleeved on the outer wall of the cable, and the conical coil spring can fit cables of different sizes.

[0026] Operation step three: When the cable moves to the drying chamber, the sponge block adheres to the outer wall of the cable to block the water vapor on the surface of the cable. The control panel controls the high-speed fan on the inner wall of the high-speed fan to operate, and the high-speed fan blows away the water vapor on the surface of the cable. At the same time, the control panel controls the operation of the exhaust pump, and the exhaust pump extracts the water vapor inside the drying chamber through the air inlet shell. The high-speed fan and the exhaust pump cooperate to keep the surface of the cable dry.

[0027] Operation step 4: The control panel controls the servo motor to operate, so that the driving shaft of the servo motor drives the driving gear to operate, and then the driving gear engages and drives the ring gear to rotate. When the ring gear rotates, the ring gear drives the fixed rod to move in a circle; Operation step five: when the fixed rod moves, the fixed rod drives the push plate to move, and then the push plate applies thrust to the sliding rod through the sliding rod. The sliding rod slides inward on the inner wall of the limiting sleeve under the force, and then the sliding rod pushes the scraper member to move inward. The ring gear drives multiple groups of scraper members to move inward at the same time through the transmission member, and then the scraper member fits on the outer wall of the cable located in the inner cavity of the cleaning chamber, and the scraper member cleans the original pre-treated cable.

[0028] Operation step six: When the size of the cable is large, when its scraper shell fits on the surface of the cable, due to the large diameter of the cable, its multiple groups of scraper shells cannot contact each other. Since the sliding scraper cannot be blocked by the scraper shell on one side, the sliding rod continues to move inward, and the sliding rod drives the fixed block to move inward. At this time, the fixed block pushes the connecting plate to move, and then the connecting plate applies thrust to the sliding scraper through the connecting piece.

[0029] Operation step seven: Since the connecting piece is a symmetrical structure, the two sets of connecting plates apply opposite thrusts at this time, so that the two sets of sliding scrapers move to both sides from the opposite side walls of the scraper shell respectively, and scraper plates are arranged on the outer walls of the scraper shell and the sliding scraper in sequence from front to back. The scraper piece is provided with multiple groups of annular structures and are respectively located in the inner cavity of the fixed base. The sliding scraper and the scraper shell cooperate to drive the scraper plate to fit the outer wall of the cable to scrape away impurities.
