Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to an insulating sheath extrusion device for cable production. Background Art

[0002] The insulation sheath extrusion device for cable production is a key equipment used to form the outer protective layer of the cable through the extrusion process.

[0003] The thermoplastic material is extruded forward by an extruder and formed through a mold. The main parameters that need to be controlled in this process include temperature, pressure and speed. The formation of the insulating sheath depends on a specially designed mold. Through this mold, the plastic is extruded into the desired shape and coated on the outside of the cable conductor to form a protective layer. The existing extrusion device for cable insulating sheaths does not have the ability to adjust the caliber, so the specifications of the produced cable insulating sheaths are fixed values, and the applicability of the equipment production is not high. Therefore, we propose an insulating sheath extrusion device for cable production to solve the deficiencies in the existing technology. Utility Model Content

[0013] Compared with the related art, the insulating sheath extrusion device for cable production proposed by the utility model has the following beneficial effects:

[0020] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0021] Reference Figure 1-4 , please refer to Figure 1-Figure 4 ,in, Figure 1 A schematic diagram of the three-dimensional structure of an insulating sheath extrusion device for cable production proposed by the utility model Figure 1 ; Figure 2 A schematic diagram of the three-dimensional structure of an insulating sheath extrusion device for cable production proposed by the utility model Figure 2 ; Figure 3 A schematic diagram of the three-dimensional structure of an insulating sheath extrusion device for cable production proposed by the utility model Figure 3 ; Figure 4 The utility model discloses a partial three-dimensional structure disassembly diagram of an insulating sheath extrusion device for cable production. The insulating sheath extrusion device for cable production comprises: a cable insulating sheath production extruder 1, and an extrusion assembly 8 is arranged at the end of the cable insulating sheath production extruder 1.

[0022] In the present embodiment, the extrusion assembly 8 includes a second motor 81, a first gear 82 is fixedly mounted on the output end of the second motor 81, a rotating shaft 83 and an extrusion outlet 87 are mounted on the side of the cable insulation sheath production extruder 1, a second gear 84 is fixedly mounted on the end of the rotating shaft 83, the second gear 84 is meshed with the first gear 82, a connecting rod 85 is fixedly connected to the side of the rotating shaft 83, an arc-shaped support 86 is fixedly mounted on the end of the connecting rod 85, three receiving cylinder seats 810 are fixedly mounted on the bottom of the arc-shaped support 86, three cable insulation sheath extrusion cylinders 811 of different sizes are fixedly mounted on the top of the arc-shaped support 86, the cable insulation sheath extrusion cylinder 811 is connected to the receiving cylinder seat 810, a sliding sealing sleeve 88 is slidably mounted on the outer side of the extrusion outlet 87, and an electric telescopic rod 89 is mounted on the side of the sliding sealing sleeve 88.

[0023] Through the arrangement in the above manner, three cable insulation sheath extrusion barrels 811 of different sizes are fixedly installed on the top of the arc support 86. By rotating the arc support 86, the receiving barrel seat 810 connected to the inner side of the cable insulation sheath extrusion barrel 811 is made to correspond to the extrusion outlet 87, thereby completing the docking of the extrusion outlet 87 with the cable insulation sheath extrusion barrels 811 of different sizes. Then, the cable insulation sheaths extruded and molded by the end of the cable insulation sheath production extruder 1 have different sizes, and their sizes correspond to the inner diameter size of the cable insulation sheath extrusion barrel 811, so that the device has the function of producing cable insulation sheaths of multiple specifications.

[0024] In this embodiment, the electric telescopic rod 89 is symmetrically arranged along both sides of the sliding sealing sleeve 88, and the inner diameter of the sliding sealing sleeve 88 is matched with the outer diameter of the receiving cylinder seat 810.

[0025] By the above arrangement, the electric telescopic rods 89 are symmetrically arranged along the two sides of the sliding sealing sleeve 88. Then, when the two electric telescopic rods 89 are synchronously driven, the driving force of the sliding sealing sleeve 88 is not eccentric, so that the sliding sealing sleeve 88 is more stable when sliding.

[0026] In this embodiment, the first gear 82 has a smaller number of teeth than the second gear 84 .

[0027] By the above-mentioned arrangement, the number of teeth of the first gear 82 is smaller than that of the second gear 84. When the second motor 81 drives the first gear 82 to rotate, the rotation speed of the second gear 84 is reduced under the meshing transmission action, and the stability during rotation is improved, thereby improving the stability when switching the cable insulation sheath extrusion barrel 811.

[0028] In this embodiment, a first motor 4 is fixedly installed on the right side of the cable insulation sheath production extruder 1, and an output end of the first motor 4 rotates through the inside of the cable insulation sheath production extruder 1 and a feeding dragon 7 is fixedly installed on the output end of the first motor 4.

[0029] By the arrangement in the above manner, when the first motor 4 rotates, it drives the feeding dragon 7 inside the cable insulation sheath production extruder 1 to rotate, and transports the melted liquid plastic in the heating cylinder 5 to the extrusion outlet 87 on the left.

[0030] In this embodiment, a base 2 is provided at the bottom of the cable insulation sheath production extruder 1, and a controller 3 is installed on the side of the base 2. The controller 3 is a PLC compilable controller.

[0031] In this embodiment, a heating cylinder 5 is installed on the upper side of the cable insulation sheath production extruder 1, and a solenoid valve 6 is installed on the heating cylinder 5.

[0032] Through the above-mentioned arrangement, the electromagnetic valve 6 provides an opening and closing state of the connection port between the heating cylinder and the cable insulation sheath production extruder 1.

[0033] The working principle of an insulating sheath extrusion device for cable production provided by the utility model is as follows:

[0034] When in use, the raw materials for production are added into the heating cylinder 5 for heating and melting to generate a plastic solution, the first motor 4 is started to drive the feeding dragon 7 to rotate, and the solenoid valve 6 is opened at the same time, and the liquid plastic flows into the cable insulation sheath production extruder 1, and then the liquid plastic is extruded and transported to the extrusion outlet 87 under the action of the feeding dragon 7. The plastic flows from the extrusion outlet 87 to the receiving cylinder seat 810, and finally extruded through the cable insulation sheath extrusion cylinder 811 connected to the receiving cylinder seat 810 to generate a cable insulation sheath. The outer diameter of the generated cable insulation sheath is compatible with the inner diameter of the cable insulation sheath extrusion cylinder 811. When it is necessary to produce cable insulation sheaths of different sizes, the corresponding cable insulation sheath extrusion cylinder 811 can be switched before the equipment is operated.

[0035] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
