Description

Technical Field

[0001] The utility model relates to the technical field of extruders, in particular to a multi-color cable rubber sheath extruder. Background Art

[0002] Cables are usually made of several or several groups of wires (at least two in each group) twisted together in a rope-like style. Each group of wires is insulated from each other and often twisted around a center wire. The entire outside is covered with a highly insulating covering. Cables have the characteristics of being powered inside and insulated outside.

[0003] Extruder is a commonly used equipment in the cable production process. The working process of the extruder is that the raw materials enter the barrel through the hopper and move forward under the rotation of the screw. During the forward movement, the raw materials are heated by the barrel, sheared and compressed by the screw to melt the materials. The pressure and shear force generated by the rotation of the screw make the materials fully plasticized and mixed evenly. Then, through the die and molds of different shapes, the plastic is extruded into continuous plastic layers of various shapes required and wrapped on the wire core. It is an indispensable equipment in the cable production process.

[0004] With the modernization of optical communication and power transmission industries, the transmission of optical, electrical and control signals requires multiple cables to be laid together. For the convenience of engineering installation and maintenance, cables need to be distinguished by different colors, or multi-color cables should be used. However, the existing extrusion equipment for producing multi-color cable insulation layers is relatively complex in structure and has a high production cost.

[0005] For example, in the patent document with the patent number CN201910472520.5 and the name "Double-layer Cable Extruder Head", a double-layer cable extruder head is disclosed, which includes a shell, a first glue guide component, a second glue guide component and an outlet component. The shell is provided with a first glue inlet, a second glue inlet and an installation channel; the first glue guide component is arranged in the installation channel, and a first plug-in channel is arranged in the first glue guide component, and a first glue guide channel is formed between the first glue guide component and the installation channel; the second glue guide component is arranged in the first plug-in channel, and the second glue guide component has two threading holes, and a second glue guide channel is formed between the second glue guide component and the first plug-in channel; the outlet component is arranged at the front of the installation channel, and an outlet hole coaxial with the threading hole is arranged on the outlet component, and a third glue guide channel is formed between the outlet component and the first glue guide component. The above-mentioned extruder head needs to be equipped with a more complex extruder line for feeding, which is troublesome to assemble and arrange. The extruder head is difficult to disassemble and clean. In addition, it is also difficult to adjust and replace different extruder heads according to the specifications of the cable.

[0006] Therefore, in order to reduce the difficulty of assembling and disassembling the extruder head, improve the extruder's adaptability to multi-color extruder heads of different sizes and specifications, reduce the difficulty of replacing the extruder head, and improve production efficiency, it is necessary to improve and develop the structure of the extruder.

[0035] like Figures 1 to 5 As shown, this embodiment provides a multi-color cable sheath extruder, including a main extrusion component 1, an auxiliary extrusion component 2 and a double-layer extrusion head 3, the double-layer extrusion head 3 is provided with a main inlet 301 and an auxiliary inlet 302 connected to a cable channel 303, the output end of the main extrusion component 1 is detachably connected to the main inlet 301, the output end of the auxiliary extrusion component 2 is vertically downwardly connected to the auxiliary inlet 302, the auxiliary extrusion component 2 is connected to a lifting screw 4, and the bottom of the lifting screw 4 is slidably sleeved with a translation track 5.

[0036] In actual use, since the main extrusion assembly 1 and the auxiliary extrusion assembly 2 are both detachably connected to the double-layer extrusion head 3, and the position of the auxiliary extrusion assembly 2 can be adjusted as needed using the lifting screw 4 and the translation track 5, the double-layer extrusion head 3 can be quickly assembled and disassembled and various specifications of the double-layer extrusion heads 3 with auxiliary inlets 302 at different positions can be adapted, effectively reducing the maintenance difficulty of the equipment and improving production flexibility. Different colors of rubber materials are respectively transported to the surface of the cable passing through the cable channel 303 through the main inlet 301 and the auxiliary inlet 302 and cooled and covered, thereby forming a cable rubber sleeve with different color mixtures on the cable surface.

[0037] A cable channel 303 is horizontally provided through the double-layer extrusion head 3, the main inlet 301 is provided at the side of the double-layer extrusion head 3, the secondary inlet 302 is provided at the top of the double-layer extrusion head 3, and the output ends of the main inlet 301 and the secondary inlet 302 are both provided at the ends of the cable channel 303.

The feed hopper 201 is arranged at the input end of the vertical extrusion sleeve 202. The vertical extrusion sleeve 202 is fixedly connected to the support frame 203. The top of the lifting screw 4 is rotatably sleeved in the bearing sleeve 401 at the bottom of the support frame 203, and the bottom thread of the lifting screw 4 is sleeved with a lifting thread seat 402.

[0042] The vertical extrusion sleeve 202 is provided with a rotating screw 204, the feed hopper 201 is provided with a stirring rod 7, the top of the stirring rod 7 is connected with a driving connecting rod 701, the driving connecting rod 701 is hinged to the outer side of the stirring driving wheel 702, the stirring driving wheel 702 and the rotating screw 204 are coaxially connected with a driving pulley 801, and the driving pulley 801 is connected to the output end of the rotating motor 8 through a synchronous belt 802. The raw material stirring mechanism and the extrusion screw mechanism of the auxiliary extrusion component 2 are driven by the same power source, the equipment has a high degree of integration, can effectively reduce the equipment volume, and reduce the load of the supporting mechanism of the auxiliary extrusion component 2.

[0043] The top of the lifting threaded seat 402 is coaxially connected with a turntable handle 404 through a thrust bearing 403, and the central thread of the turntable handle 404 is sleeved on the lifting screw 4. Rotating the turntable handle 404 can drive the screw to move up and down, thereby adjusting the lifting of the auxiliary extrusion assembly 2, which is convenient to use.

[0044] The bottom of the lifting thread seat 402 is slidably sleeved on the translation track 5, and the bottom thread of the lifting thread seat 402 is serially connected with a translation drive screw 501. The horizontal position of the auxiliary extrusion assembly 2 can be quickly adjusted by rotating the translation drive screw 501 through the translation handle 502, so that the output end of the auxiliary extrusion assembly 2 can be connected to the auxiliary inlet 302 at different positions.

[0045] The main extrusion assembly 1 and the translation track 5 are both mounted on a frame 9, and the translation track 5 is correspondingly arranged on one side of the output end of the main extrusion assembly 1.
