Description
Technical Field
[0001] The present application relates to the technical field of cable processing, and in particular to a cable extruder. Background Art
[0002] Cable extruder is one of the most common production equipment in the cable production industry. Cable extruder is a device used for extrusion molding of plastic coatings such as the outer insulation layer of the cable.
[0003] In the related art, an extrusion die is provided at the front end of the cable extruder, and the molten cable outer insulation material wraps the cable core and is extruded from the extrusion die. After the extrusion is completed, the cable is reeled in by a reel-in wheel.
[0004] Some cable insulation layers are made of silicone. Since silicone has poor thermal conductivity, it takes longer for the silicone insulation layer to transfer heat to the surrounding environment during the extrusion process. This may cause the cable's outer insulation layer to be reeled in before it is completely cooled after extrusion. At this time, the insulation layers that are close to each other on the reel will stick together, affecting the subsequent sale and use of the cable. There is room for improvement. Utility Model Content
[0005] The purpose of the present application is to provide a cable extruder to solve the problem in the above-mentioned related technology that, due to the poor thermal conductivity of silicone materials, when the extruded cables are reeled up, the insulating layers close to each other on the reeling wheel may stick together, affecting the subsequent sale and use.
[0006] The present application provides a cable extruder adopting the following technical solution:
[0007] A cable extruder comprises a base and an extrusion assembly arranged on the base, an anti-adhesion assembly is arranged on the side of the extrusion assembly, the anti-adhesion assembly comprises anti-adhesion powder, a storage box for accommodating the anti-adhesion powder and a box cover arranged on the upper opening of the storage box, and an inlet and an outlet for cables to pass through are respectively arranged on opposite sides of the storage box.
[0008] By adopting the above technical solution, the cables extruded by the extrusion assembly enter from the cable inlet and outlet of the storage box. When the cables pass through the storage box, the outer surface of their own insulation layer is covered with anti-sticking powder, and then the cables are rolled up by the winding wheel. This arrangement reduces the possibility of adhesion between the insulation layers of the cables wound on the winding wheel.
[0009] Optionally, the storage box is provided with a rotating shaft, stirring blades arranged at both ends of the rotating shaft and rotating in opposite directions, and a driving member for driving the rotating shaft to rotate. The rotating shaft is parallel to the length direction of the storage box, and the stirring blades on the rotating shaft are used to squeeze the anti-sticking powder toward the middle of the storage box.
[0010] By adopting the above technical solution, due to the setting of the rotating shaft, stirring blades and driving parts, the anti-sticking powder inside the storage box can be concentrated to the middle of the storage box, so that the height of the anti-sticking powder in the middle of the storage box is higher than other positions, which is convenient for coating the anti-sticking powder on the outer surface of the cable insulation layer.
[0011] Optionally, the storage box is provided with a support plate and a limiting member on the support plate on the outer side surfaces of the wire inlet and the wire outlet, and the limiting member includes a limiting roller relatively arranged on the support plate, and the limiting roller is rotatably connected to the support plate.
[0012] By adopting the above technical solution, when the cables enter or exit the storage box, the cables are limited by the setting of the limiting rollers, thereby reducing the possibility of the cables being damaged by friction with the edges of the cable inlet and the cable outlet.
[0013] Optionally, a partition plate is provided inside the storage box near the cable inlet and the cable outlet, and a gap is opened on the partition plate for the cables to pass through.
[0014] By adopting the above technical solution, due to the provision of the partition plate, when the storage box is in use, the anti-sticking powder inside the storage box can be discharged from the wire inlet or the wire outlet.
[0015] Optionally, one side of the box cover is hinged to the upper opening of the storage box, and the storage box is provided with a limiting groove at the inner edge of the upper opening for the box cover to be rotatably placed.
[0016] By adopting the above technical solution, the box cover is rotatably connected to the upper part of the storage box, which makes it easy to open the box cover and add and replenish the anti-sticking powder later.
[0017] Optionally, the box cover is provided with an observation window located in the middle of the storage box.
[0018] By adopting the above technical solution, it is convenient for staff to observe the consumption of anti-sticking powder inside the storage box.
[0019] Optionally, a traction handle is provided on the side of the box cover away from the storage box.
[0020] By adopting the above technical solution, it is convenient for the staff to open the box cover and replenish the anti-sticking powder.
[0021] Optionally, the storage box is provided with a protective cover on the outer side of the cable outlet, which is sleeved on the outside of the support plate. A cleaning block is provided on the inner wall of the protective cover. The cleaning block is provided with a limiting hole for the cable to pass through. The protective cover is provided with a connecting gap for the cable to pass through. A collection box is provided below the protective cover.
[0022] By adopting the above technical solution, when the cable is coated with anti-sticking powder, a cleaning block can be used to remove excess anti-sticking powder on the outer surface of the cable, so that the anti-sticking powder falls into the collection box for subsequent recycling, and finally the cable is reeled up by the reel-up wheel.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. Through the setting of the storage box and anti-sticking powder, the cables extruded by the extrusion assembly enter from the cable inlet and outlet of the storage box. When the cables pass through the storage box, the outer surface of their own insulation layer is covered with anti-sticking powder, and then the cables are reeled up by the reel. This setting reduces the possibility of adhesion between the insulation layers of the cables wound on the reel.
[0025] 2. Due to the arrangement of the rotating shaft, stirring blades and driving parts, the anti-sticking powder inside the storage box can be concentrated to the middle of the storage box, so that the height of the anti-sticking powder in the middle of the storage box is higher than that in other positions, which is convenient for coating the anti-sticking powder on the outer surface of the cable insulation layer.

DETAILED DESCRIPTION
[0036] The present application is further described in detail below in conjunction with all the accompanying drawings.
[0037] Example:
[0038] Reference Figure 1 and Figure 2 A cable extruder comprises a base 1 and an extrusion assembly 2 arranged on the base 1, an anti-adhesion assembly 3 is arranged on the side of the extrusion assembly 2, the anti-adhesion assembly 3 comprises anti-adhesion powder (powdered, not shown in the figure), a storage box 31 for accommodating the anti-adhesion powder and a box cover 32 arranged on the storage box 31, and opposite sides of the storage box 31 are respectively provided with an inlet 311 and an outlet 312 for cables to pass through; the extruded cable enters from the inlet 311 of the storage box 31 and exits from the outlet 312, the outer surface of the cable is covered with anti-adhesion powder, and then the cable is reeled up by a reel-up wheel (not shown in the figure), and the cable is always in a taut state during this process.
[0039] In other embodiments, after the anti-sticking powder is covered and before the cable is reeled up by the reel-up wheel, a water-passing process is provided, in which the cable is passed through cooling water in a water tank. This is a conventional structure and will not be described in detail here. It is used to further cool the insulation layer of the extruded cable before finally reeling it up by the reel-up wheel.
[0040] Reference Figure 1 The extrusion component 2 melts the plastic particles and coats the surface of the copper wire through heating, melting, injection and other processes. This is a conventional extrusion structure and will not be described here. The anti-sticking powder is usually talcum powder or a talcum powder mixture. Talc has excellent lubricity and anti-stickiness, which can effectively prevent the insulation layer of the cable from sticking together during the winding process.
[0041] Reference Figure 3 and Figure 4The storage box 31 is provided with a rotating shaft 33, stirring blades 331 arranged at both ends of the rotating shaft 33 and rotating in opposite directions, and a driving member 34 for driving the rotating shaft 33 to rotate. The outer side of the storage box 31 is provided with a control console for controlling the driving member 34. The driving member 34 includes a motor 341 and a transmission belt 342. The motor 341 drives the rotating shaft 33 to rotate through the transmission belt 342. This is a conventional driving structure and is not described here. After the rotating shaft 33 is installed, the rotating shaft 33 is parallel to the length direction of the storage box 31. The stirring blades 331 on the rotating shaft 33 are used to squeeze the anti-sticking powder to the middle of the storage box 31, so that the height of the anti-sticking powder in the middle of the storage box 31 is higher than that of other positions.
[0042] Reference Figure 4 One side of the box cover 32 is hinged to the upper opening of the storage box 31. The storage box 31 is provided with a limit groove 313 at the inner edge of the upper opening for the box cover 32 to rotate and place. At the same time, a traction handle 321 is provided on the side of the box cover 32 away from the storage box 31. An observation window 322 located in the middle of the storage box 31 is fixed on the box cover 32. The observation window 322 is made of transparent material, which is convenient for observing the consumption of the anti-sticking powder inside the storage box 31.
[0043] Reference Figure 5 , the interior of the storage box 31 is close to the line inlet 311 (see Figure 3 ) and the outlet 312 are provided with two partition plates 314, the partition plates 314 are fixedly connected to the inner wall of the storage box 31, and the partition plates 314 are provided with a clearance gap 3141 for the cable to pass through, so as to reduce the anti-sticking powder inside the storage box 31 from the inlet 311 (see Figure 3 ) or the possibility of discharge from outlet 312.
[0044] Reference Figure 3 , the storage box 31 is located at the inlet 311 and the outlet 312 (see Figure 2 ) are fixedly provided with a support plate 35 and a limiting member 36 on the support plate 35, wherein the limiting member 36 comprises two limiting rollers 361 relatively vertically arranged on the support plate 35, wherein the limiting rollers 361 are rotatably connected to the support plate 35, and thus the cable is limited when the cable enters and exits the storage box 31, so as to reduce the cable and the cable inlet 311 and the cable outlet 312 (see Figure 2 ) possibility of edge friction.
[0045] Reference Figure 6 and Figure 7 A protective cover 37 is provided on the outer side of the outlet 312 of the storage box 31 and is sleeved on the outside of the support plate 35. A connecting notch 371 is opened on the protective cover 37 for the cable to pass through. A cleaning block 38 is fixed to the inner wall of the protective cover 37 by glue. The cleaning block 38 is made of sponge and is used to remove excess anti-sticking powder on the outer surface of the cable.
[0046] Reference Figure 7 and Figure 8 The cleaning block 38 is provided with a limiting hole 381 for the cable to pass through, the connecting hole is coaxially arranged with the limiting hole 381, and a collecting box 39 is arranged below the protective cover 37. When the cleaning block 38 removes the excess anti-sticking powder on the outer surface of the cable, the anti-sticking powder falls into the collecting box 39 for subsequent recycling.
[0047] The implementation principle of the embodiment of the present application is:
[0048] The extruded cables enter from the cable inlet 311 and exit from the cable outlet 312 of the storage box 31, and the outer surface of the cables is covered with anti-sticking powder. Then, the cleaning block 38 is used to remove the excess anti-sticking powder on the outer surface of the cables, so that the anti-sticking powder falls into the interior of the collection box 39, and finally the cables are reeled up by a reel-up wheel (not shown in the figure).
