Description

Technical Field

[0001] The utility model relates to the technical field of cable extruders, in particular to a material-guiding type cable extruder. Background Art

[0002] A wire extruder is a device used to produce wires and cables. It is mainly used to extrude plastic or metal materials into cables of various shapes. The device is usually composed of an extruder, a heating system, a cooling system, a tractor and a cutter.

[0003] During operation, the raw materials are first placed in the hopper of the extruder, and the screw pushes the raw materials into the heating system for heating and melting. Then, the molten raw materials are extruded through the die to form the shape of the cable. Next, the cable is cooled by the cooling system to solidify and form. Finally, the cable is stretched and cut by the tractor and cutter to finally produce the wire and cable products that meet the requirements.

[0004] A general cable extruder cools the cable with water after extruding it. However, since the avoidance slot at the side of the water cooling box is lower than the cable during cooling, it is difficult for the water used for cooling to completely submerge the cable, so the cooling effect cannot be guaranteed, affecting the stability of the cable structure. Therefore, the above problems need to be improved. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a material-guiding cable extruder, comprising an extruder, a water-cooling mechanism for cooling and shaping the cable is provided at the front end of the extrusion head of the extruder, and an air-drying device for drying the cable surface is provided at the front end of the water-cooling mechanism; the water-cooling mechanism comprises a water reservoir and a plurality of water-cooling boxes installed inside the water reservoir.

[0007] Preferably, a cooling pipe is installed above the water reservoir, a plurality of stop valves are equidistantly connected on the cooling pipe, one end of the cooling pipe is connected to a circulation pipe, a water pump is provided inside the water reservoir, and the lower end of the circulation pipe is connected to the water outlet end of the water pump inside the water reservoir.

[0012] Preferably, the reflux groove is a notch-shaped structure with a high front end and a low rear end, and a guide plate is installed at the bottom of the rear end of the reflux groove. The guide plate is also high at the front end and low at the rear end, and the rear end of the guide plate is inserted into the reflux port of the water reservoir, and the cross-section of the guide plate is a U-section shape.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: in the utility model, when the cable core passes through the extruder head, the extruder wraps the cable shell material in a molten state around the outer ring of the core through the extruder head to form a protective layer shell of the cable, and the formed cable shell is then cooled by a water cooling mechanism for rapid shaping. During water cooling, the avoidance slots at both ends of the water cooling box are used for the passage of the cable, and the water in the water cooling box is blocked by a sponge pad so that the water in the water cooling box can overflow the cable surface, thereby improving the cooling effect and ensuring the mechanical properties of the cable. Finally, the moisture used for cooling the cable shell is dried by an air drying device for subsequent cable winding and storage. While air drying, the water-cooled cable can be further cooled, and the reflux groove at the bottom of the wire hole of the air drying box and the guide plate connected thereto can also discharge the moisture dripping during the air drying process back into the water reservoir.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Example: See Figure 1-4 A material-guiding cable extruder 1 in the utility model comprises an extruder 1, a water-cooling mechanism for cooling and shaping the cable is provided at the front end of the extruder head of the extruder 1, and an air-drying device for drying the surface of the cable is provided at the front end of the water-cooling mechanism; the water-cooling mechanism comprises a water reservoir 2 and a plurality of water-cooling boxes 11 installed inside the water reservoir 2; when the cable core passes through the head of the extruder 1, the extruder 1 wraps the cable casing material in a molten state on the outer ring of the core through the head of the extruder 1 to form a protective layer casing of the cable, and the formed cable casing is cooled by the water-cooling mechanism so as to quickly shape and ensure the mechanical properties of the cable, and finally the moisture used for cooling the cable casing is dried by the air-drying device so as to facilitate the subsequent cable winding and storage.

[0022] In the utility model, a cooling pipe 4 is installed above the water reservoir 2, and a plurality of stop valves 5 are equidistantly connected on the cooling pipe 4. One end of the cooling pipe 4 is connected to a circulation pipe 3. A water pump is provided inside the water reservoir 2, and the lower end of the circulation pipe 3 is connected to the water outlet end of the water pump inside the water reservoir 2. Three water cooling boxes 11 are provided in the water reservoir 2, and a plurality of fixing rods connected to the water reservoir 2 are provided at the bottom end of the water cooling box 11. The formed cable passing through the head of the extruder 1 is first cooled in a water cooling mechanism, and the cable is cooled step by step by the three water cooling boxes 11 in the water reservoir 2 to improve the water cooling effect. The water in the water cooling box 11 submerges the cable under the action of the sponge pad 9, thereby ensuring uniform heat dissipation of the cable, and the overflowing water will flow back into the water reservoir 2, and then the cable is circulated and cooled under the action of the water pump and the circulation pipe 3, thereby saving water.

[0023] In the utility model, open grooves corresponding to the avoidance notches are provided on the upper part of the two side walls of the water cooling box 11, and a wire roller 12 is rotatably provided in the middle of the water cooling box 11; the wire roller 12 supports the cable and facilitates the sliding of the cable, which is convenient for subsequent cable transportation.

[0024] In the utility model, both ends of the water reservoir 2 are provided with avoidance slots, and sponge pads 9 are installed in the avoidance slots and the open slots. A reflux port 10 is also provided below the avoidance slots on the side wall of the water reservoir 2. The air drying device includes an air drying box 6, a plurality of mounting ports provided on the top of the air drying box 6, and a fan 7 provided inside the mounting ports. A wire hole is provided inside the air drying box 6, and a drying pad 8 is installed at the front end of the wire hole. A reflux groove 13 is provided on the inner bottom surface of the wire hole along the length direction. The reflux groove 13 is a groove with a high front end and a low rear end. The reflux groove 13 has a mouth-shaped structure, and a guide plate 14 is installed at the bottom of the rear end of the reflux groove 13. The guide plate 14 is also high at the front end and low at the rear end. The rear end of the guide plate 14 is inserted into the reflux port 10 of the water reservoir 2, and the cross-section of the guide plate 14 is a U-section shape. The fan 7 is used to dry the cable after water cooling, and at the same time, the cable can be air-cooled, which achieves multiple goals at one stroke. The reflux groove 13 in the wire hole can drain the water dripping from the air drying back to the water reservoir 2 through the guide plate 14, so as to prevent the water from accumulating in the air drying box 6 and avoid waste.

[0025] Working principle: When the utility model is used, firstly, the electrical components of the device are powered on, and after the wire chips are passed through the corresponding positions of the various mechanisms of the device in turn, the power supply of the extruder 1 is started, and the head of the extruder 1 covers the cable shell material in a molten state on the surface of the cable. The formed cable first passes through the three water cooling boxes 11 in the water reservoir 2, and the wire roller 12 in the middle of the water cooling box 11 provides support for the bottom end of the cable while conveying the cable forward. When the cable passes through the avoidance slots at both ends of the water cooling box 11, the sponge pad 9 is squeezed, and the sponge pad 9 covers the cable while The water in the water cooling box 11 is blocked so that the water overflows over the cable and then flows into the water reservoir 2 from above the sponge pad 9. The water in the water reservoir 2 is then transported from the circulation pipe 3 to the cooling pipe 4 by a water pump. The water stop valve is opened to circulate and cool the water in the water reservoir 2. The water-cooled cable is transported to the air drying box 6 and dried by the fan 7. The water dripping during the air drying process flows back to the water reservoir 2 through the reflux groove 13 and the guide plate 14. The air-dried cable is finally wiped by the drying pad 8 and then transported to the subsequent winding mechanism for winding and storage.
