[0026] like Figure 2 As shown, the material discharge assembly 2 includes a hopper 14 , and a second groove 25 is formed on the inner wall of the hopper 14 .

[0028] like Figure 5 As shown, a detachably connected positioning strip 15 is provided in the opening 23, and the specific connection method includes but is not limited to snap-on connection. The size of the positioning strip 15 matches the opening 23, and a windshield 16 is fixedly connected to one side of the positioning strip 15. A plurality of ventilation holes are provided on the windshield 16. The windshield 16 is arranged on the top of the baffle 17. The windshield 16 is arranged in the first groove 24, and the baffle 17 is arranged in the second groove 25. The opening 23 is connected to one end of the first groove 24, and the other end of the first groove 24 is connected to the second groove 25. The hopper 14 is connected to the bottom of the drying box 5, and the material collection port 22 is connected to the placement plate 10.
[0029] like Figure 3 As shown, the drying mechanism 4 includes a heating bellows 11, which is an existing device and will not be elaborated on here. One side of the outer wall of the heating bellows 11 is connected to an air outlet duct 12, which is connected to the drying box 5. The other side of the outer wall of the heating bellows 11 is connected to a return air duct 13, which is connected to the drying box 5. The heating bellows 11 provides a source of hot air for the drying box 5.
[0030] like Figure 6 As shown, the bottom of the placement plate 10 is connected to the discharge assembly 3 to transport the preheated raw materials to the next device.
[0031] The material discharging assembly 3, the material drying mechanism 4 and the motor 20 are electrically connected.
[0032] Working principle: In one embodiment, the heating air box 11 is started, and the hot air from the heating air box 11 is sent into the drying box 5 along the air outlet duct 12, and then flows into the heating air box 11 from the return air duct 13. The positioning strip 15 is held by hand, and the baffle 17 is inserted along the opening 23. The baffle 17 is slowly inserted downward from the first slot 24. When the lower edge of the air shield 16 contacts the top surface of the hopper 14, and the positioning strip 15 is flush with the top of the drying box 5, it means that the air shield 16 is installed in place.
[0033] At this time, the wind shield 16 divides the drying box 5 into two areas. Since the raw materials are piled up in the hopper 14, the gap is filled and the hot air is isolated by the wind shield 16. Only a small amount of hot air flows out from the ventilation holes on the wind shield 16, and a large amount of hot air remains in the drying box 5 on the side close to the air outlet 12. At this time, the temperature in the space where the first conveyor belt 7 is located is higher than the space where the second conveyor belt 9 is located. The overly moist cable material is put in from the first lower hopper 6, and the first conveyor belt 7 is started. After a certain period of drying, the first conveyor belt 7 transports the cable material to the hopper 14, and the slightly dry cable material is put in from the second lower hopper 8, and the second conveyor belt 9 is started. The second conveyor belt 9 transports the cable material to the hopper 14. The two cable materials with different humidity flow along the material confluence port 22 to the regulating discharge component 3;
[0034] It should be noted that the first lower hopper 6 and the second lower hopper 8 can be loaded with the same or different cable materials according to production requirements, and the wind shield 16 is replaceable. Figure 7 As shown, when the cable material is dried under the same conditions, since the positioning strip 15 is detachably connected, the positioning strip 15 can be rotated to invert the wind shield 16, and the positioning strip 15 can be placed in the opening 23, and the wind shield 16 is located outside the drying box 5. At this time, the temperature in the drying box 5 is uniform, and the flow rate of hot air can also be changed by adjusting the setting of the ventilation holes on the wind shield 16, such as size, number, position, etc.
[0035] In another embodiment, when the first conveyor belt 7 and the second conveyor belt 9 convey the cable material to the hopper 14, the motor 20 is started, the motor 20 controls the shaft 21, the shaft 21 drives the flap 18 to swing left and right, the flap 18 applies external force to the cable material, and when the flap 18 is in a vertical position, the swing amplitude of the flap 18 is controlled not to exceed 80° to avoid hitting the baffle 17. The swing of the flap 18 can accelerate the falling of the cable material, and at the same time, it can prevent congestion inside the hopper 14, and the material can also flow from the through hole in the flap 18.
[0036] The device can divide the drying box 5 into two spaces by arranging a windshield 16 in the drying box 5. The hot air stock in the two spaces in the drying box 5 is changed according to the ventilation holes on the windshield 16, so that a temperature difference is generated between the two spaces. By arranging a first lower hopper 6 and a second lower hopper 8, two different cable materials can be dried. By arranging a flap 18 on the baffle 17, the falling of the cable material in the hopper 14 can be accelerated and congestion can be prevented, thereby solving the problems raised in the background technology.
