Description

Technical Field

[0002] A cable is usually a rope-like cable twisted together by several or several groups of conductors (at least two in each group). Each group of conductors is insulated from each other and often twisted around a center. The entire outer surface is covered with a highly insulating covering layer. The cable has the characteristics of internal power supply and external insulation. At present, when producing cables, it is necessary to sheath the outer surface of the cable conductor to protect the cable conductor and avoid damage to the cable conductor, and it has an insulating effect. When producing the cable sheath, it is necessary to heat and melt the raw materials and then introduce them into an extrusion device for extrusion production, and it needs to be cooled after extrusion. However, the current existing cooling methods all use water bath cooling for the cable sheath. However, water bath cooling cannot keep the cooling temperature constant, and the cable sheath cannot be fully cooled, which will lead to insufficient crystallinity inside the sheath material, affecting the mechanical and electrical properties of the material. At the same time, the cable sheath may crack. In view of this, a high-precision cable sheath extrusion device is proposed. Utility Model Content

[0023] Example 1

[0024] See also Figure 1-Figure 4 As shown, this embodiment provides a high-precision cable sheath extrusion device, including a workbench 1 and an extruder 2 for extruding the sheath, a feed barrel is installed on the upper side of the extruder 2, the material enters the extruder 2 through the feed barrel, and then the extruder 2 extrude the material into shape, a cooling chamber 3 is installed on one side of the extruder 2, a condensation component 4 is provided in the inner cavity of the cooling chamber 3, the condensation component 4 cools the extruded cable sheath, a drying component 5 is provided on the side of the cooling chamber 3 away from the extruder 2, and small water droplets will be attached to the surface of the cable sheath after cooling, and the drying component 5 dries the cooled cable sheath to remove the small water droplets and keep the cable sheath dry;

[0025] The condensation component 4 includes a first drive motor 41 embedded in the workbench 1. On the one hand, it prevents small water droplets attached to the cable sheath after cooling from dripping onto the first drive motor 41 to maintain stability and extend the service life of the first drive motor 41. On the other hand, it enables the first drive motor 41 to maintain a stable state when working. The output shaft of the first drive motor 41 is connected to the first connecting shaft 42. The first drive motor 41 starts and drives the first connecting shaft 42 to rotate. The end of the first connecting shaft 42 away from the first drive motor 41 is sleeved with a transmission belt 43. The rotating first connecting shaft 42 drives the transmission belt 43 to rotate and transmit. A round rod is inserted into the inner side wall of the transmission belt 43 away from the first connecting shaft 42, and the rotating transmission belt 43 will drive the round rod to rotate, and the round rod is movably connected to the workbench 1, so that the round rod can rotate normally.

[0026] The first connecting shaft 42 and one end of the round rod close to the workbench 1 are fixedly connected with a first gear 44, and the first gear 44 follows the first connecting shaft 42 and the round rod to perform the same movement, that is, the first gear 44 rotates, and the opposite sides of the adjacent first gears 44 are meshed with second gears 45. When the first gear 44 rotates, the teeth on the first gear 44 push the teeth on the second gear 45, so that the first gear 44 drives the second gear 45 to rotate, and a plurality of groups of second gears 45 are fixedly inserted with a support rod 46 in the middle, and the support rod 46 performs the same movement as the second gear 45 under the drive of the second gear 45, that is, the support rod 46 rotates, and the plurality of groups of support rods 46 are movably connected to the workbench 1, on the one hand, the support rod 46 can be kept to rotate normally, and on the other hand, the support rod 46 fixes the position of the second gear 45, so that the second gear 45 always remains in a state of meshing with the first gear 44.

[0027] Condensation columns 47 are installed at one end of multiple groups of support rods 46 away from the workbench 1. The condensation columns 47 rotate when the support rods 46 rotate, and adjacent condensation columns 47 rotate in the same direction. At this time, adjacent condensation columns 47 will drive the cable sheath to transmit. At the same time, the condensation columns 47 are generally I-shaped, so that the cable sheath passes through the gap between adjacent condensation columns 47. The opposite side walls of adjacent condensation columns 47 contact each other, so that the cable sheath is fully cooled. The contact part of the condensation column 47 and the cable sheath will reduce the temperature of the condensation column 47 under the action of the cable sheath, but the condensation column 47 is always in a rotating state. The contact part of the condensation column 47 and the cable sheath returns to the original cooling temperature during rotation, and the cable sheath is always at the same cooling temperature, so that the cable sheath is further fully cooled.

[0028] The drying assembly 5 includes a drying chamber 51 installed on the upper side of the workbench 1, and a plurality of groups of electric heating wires are embedded in the inner wall of the drying chamber 51. The electric heating wires generate heat to increase the temperature of the inner cavity of the drying chamber 51 to achieve the drying effect. A second drive motor 52 is installed on the upper side of the drying chamber 51. At the same time, the drying chamber 51 supports the second drive motor 52, so that the second drive motor 52 maintains a stable state during operation. The output shaft of the second drive motor 52 is connected to the second connecting shaft 53. When the second drive motor 52 is started, the second drive motor 52 will drive the second connecting shaft 53 to rotate. A fan 54 is installed at one end of the second connecting shaft 53 close to the workbench 1, and the second connecting shaft 53 will drive the fan 54 to rotate, so as to evenly disperse the temperature in the drying chamber 51 and keep the drying chamber 51 at a stable temperature value as a whole.

[0029] The upper side of the workbench 1 is equipped with equally spaced positioning plates 6, which position the extruded cable sheath so that the cable sheath always maintains a stable position. The ends of the equally spaced positioning plates 6 away from the workbench 1 are all arc-shaped. The arc-shaped positioning plates 6 fit the cable sheath more closely, so that the cable sheath can maintain stable movement under the drive of the condensation column 47.

[0030] Circular holes are provided on the opposite side walls of the cooling chamber 3 and the drying chamber 51, and the cable sheath enters the cooling chamber 3 and the drying chamber 51 through the circular holes to be cooled and dried respectively. Sponge pads are installed on the circular holes on the opposite side walls of the cooling chamber 3 and the drying chamber 51. Small water droplets will appear on the surface of the cable sheath after cooling, making the cable sheath moist. The sponge pad wipes the cable sheath for the first time when the cable sheath leaves the cooling chamber 3 and enters the drying chamber 51, so that the cable sheath can be quickly dried when entering the drying chamber 51.

[0031] A fixing plate is symmetrically installed on the upper side of the cooling chamber 3 located in the inner cavity of the drying chamber 51. The fixing plate allows the cable sheath to maintain a stable trajectory when moving, that is, it always moves within the arc of the positioning plate 6. Absorbent cloth is installed on the opposite side walls of adjacent fixing plates. During the movement, the absorbent cloth absorbs most of the small water droplets on the surface of the cable sheath, thereby further accelerating the drying speed of the cable sheath in the drying chamber 51.

[0032] When the high-precision cable sheath extrusion device of this embodiment is used, the first drive motor 41 is provided to drive the first gear 44 to rotate, thereby rotating the multiple groups of second gears 45, thereby driving the multiple groups of condensation columns 47 to rotate, so that the cable sheath extruded by the extruder 2 passes through the gaps between the multiple groups of condensation columns 47, and the rotating condensation columns 47 keep the cable sheath at the same cooling temperature, so that the cable sheath is fully cooled and the internal material of the cable sheath is completely crystallized, thereby avoiding cracking caused by incomplete cooling of the cable sheath. At the same time, a drying component 5 is provided to dry small water droplets generated on the surface of the cable sheath during the cooling process, so that the cable sheath remains dry, thereby ensuring the quality of the cable sheath.
