DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figures 1 to 9 The present invention provides a technical solution: a network cable extrusion device and method, comprising an extruder 1 and a water tank for cooling the extruded cable 2, a base 3 for supporting the cable 2 is provided between the extruder 1 and the water tank, and an effective structure for calibrating the protective layer on the extruded and uncooled cable 2 is provided on the base 3;

[0042] The effect structure includes a transverse extension plate 10 fixedly connected to the base 3, a freely sliding transverse shift seat 11 is provided on the transverse extension plate 10, a support guide roller 18 for supporting the cable 2 is fixedly rotated on the transverse shift seat 11, the transverse shift seat 11 is located on the side of the base 3 facing the extruder 1, and a transverse shift assembly is provided on the base 3 to drive the transverse shift seat 11 to reciprocate in the horizontal direction;

[0043] The base 3 includes two sets of side plates formed in one piece, and a set of directional hollow shafts 4 for the cables 2 to pass through are respectively rotated on the two sets of side plates, and a correction component for reducing the eccentricity problem of the cables 2 is provided on the directional hollow shafts 4;

[0044] A circulation component for pre-cooling the cable 2 that has passed through the deviation correction component is provided on the side of the base 3 facing the water tank.

[0045] like Figure 1 and Figure 2As shown, the cable 2 extruded from the extruder 1 is pulled out from the die head thereon, and the cable 2 is placed on the support guide roller 18. The support guide roller 18 supports the extruded cable 2 to prevent the cable 2 from sagging due to gravity, which helps to maintain the uniformity of the sheath and reduce sagging. The support guide roller 18 can rotate freely and its surface is smoothed, which can reduce friction damage when the cable 2 passes through and maintain the integrity and quality of the sheath.

[0046] At the same time, driven by the transverse movement component, the support guide roller 18 can move freely in the horizontal direction, so that the support point of the cable 2 can change dynamically, avoiding continuous pressure on the cable 2 at a fixed position, thereby helping to evenly distribute the force on the cable 2 and reduce deformation of the sheath. By constantly changing the position of the support point, stress concentration can be alleviated to prevent the sheath and copper wire from generating excessive mechanical stress.

[0047] At the same time, the cable 2 passes through the directional hollow shaft 4 and passes through the correction component. Under the action of the correction component, it can ensure that the cable 2 is evenly supported and corrected during the sheath molding process, reducing the eccentricity problem caused by the sagging of the sheath. In addition, the cable 2 passing through the correction component first passes through the circulation component and enters the water tank for final cooling. The purpose of pre-cooling the cable 2 that is about to enter the water tank is achieved through the circulation component.

[0048] Among them, the pre-cooling process can make the sheath obtain preliminary and uniform cooling before entering the water tank, reduce the sagging or unevenness of the sheath caused by local overheating, and through pre-cooling, the cable 2 can be initially stabilized before entering the water tank, reduce the sagging or unevenness of the sheath caused by local overheating, and effectively reduce the problems of sheath sagging and high eccentricity.

[0049] Among them, the extruder 1 is mainly composed of a wire pay-off frame, a preheating device, an extruder, a die head, a traction device and a water tank, and its main functions are:

[0050] Pay-off rack: used to place and release the copper wire or optical fiber to be extruded, ensuring that the wire can enter the subsequent extrusion process continuously and smoothly;

[0051] Preheating device: used to preheat the wire, remove moisture and impurities on the surface of the wire, and improve the bonding strength between the wire and the molten plastic;

[0052] Extruder: melts and extrude plastic particles, and evenly covers the surface of the wire through the die head to form a protective layer;

[0053] Die head: used to control the shape and thickness of the extruded plastic layer to ensure that the sheath is uniform and smooth;

[0054] Traction device: used to control the moving speed of the wire, ensure that the wire maintains a uniform speed throughout the extrusion process, avoid stretching or relaxation, and ensure consistent sheath thickness;

[0055] Water Trough: Used to quickly cool and solidify the newly extruded wire, so that it can be shaped and maintain the desired size and shape.

[0056] In one of the more preferred embodiments, the transverse movement assembly includes a lateral plate 19 fixedly connected to the transverse extension plate 10, and the lateral plate 19 is provided with a positioning plate 13 which is transmission-connected to the directional hollow shaft 4 and can rotate freely in the vertical direction, and a swing rod 14 which can swing freely in the vertical direction is provided on one side of the positioning plate 13;

[0057] The top end of the swing rod 14 is fixedly rotated on the transverse shift seat 11 , and a transverse sliding groove 12 for the transverse shift seat 11 to slide horizontally is provided on the transverse extension plate 10 .

[0058] A positioning pin 15 is fixedly connected to one end of the positioning plate 13 facing the swing rod 14. The swing rod 14 is provided with an orientation groove 16 for the positioning pin 15 to slide. A limit block 17 is also slidably connected in the orientation groove 16. The limit block 17 rotates on a fixed axis on the side plate 19.

[0059] like Figure 6 and Figure 8 As shown, when the positioning plate 13 rotates freely in the vertical direction, it can drive the positioning pin 15 fixed thereon to rotate synchronously, wherein the horizontal position of the positioning pin 15 changes all the time when it rotates. Therefore, during the rotation process, the positioning pin 15 can drive the orientation slot 16 to swing freely in the vertical direction, wherein the orientation slot 16 can drive the transverse displacement seat 11 rotatably connected to its top to move in the horizontal direction when it swings.

[0060] At the same time, the positioning plate 13 performs circular motion, thereby driving the transverse shift seat 11 and the supporting guide rollers 18 arranged thereon to reciprocate in the horizontal direction, and the supporting guide rollers 18 support the extruded cable 2, so that the supporting point of the cable 2 changes dynamically, avoiding continuous pressure on the cable 2 at a fixed position, thereby helping to evenly distribute the force on the cable 2 and reduce deformation of the sheath.

[0061] It should be noted that the side plate 19 has a fixed-axis rotating limit block 17, and the limit block 17 is rotatably connected to the rocker arm 14 through the directional groove 16, and the limit block 17 is always in the directional groove 16, wherein the top fixed-axis rotating part of the rocker arm 14 is on the transverse displacement seat 11, therefore, when the rocker arm 14 swings vertically, the relative position of the limit block 17 and the directional groove 16 can be changed, thereby ensuring that the limit block 17 can always limit the rocker arm 14, so as to ensure that the rotation center point of the rocker arm 14 is always at the position of the limit block 17.

[0062] Based on the embodiment of the transverse movement assembly, the deviation correction assembly includes a plurality of groups of abutment cylinders 9 arranged above the base 3 and arranged in a ring shape and equidistantly distributed on the vertical cross section, and the outer peripheral surfaces of the plurality of groups of abutment cylinders 9 are in sliding contact with the cables 2;

[0063] The plurality of groups of the stop tubes 9 can rotate freely in the vertical direction and can revolve around the directional hollow shaft 4 as the central axis, and an inner cavity for the cable 2 to pass through is formed between the plurality of groups of the stop tubes 9 .

[0064] The two groups of directional hollow shafts 4 are both provided with a three-claw seat 5 for fixed axis rotation. Both ends of the stop tube 9 are respectively fixed axis rotation on a group of three-claw seats 5 for making way. The stop tube 9 is coaxially fixed with a side gear 7. The side gear 7 is meshingly connected with an axial gear 6. The axial gear 6 is fixedly sleeved on the directional hollow shaft 4. The side gear 7 is also meshingly connected with an internal gear ring 8. The internal gear ring 8 is fixedly connected to the base 3.

[0065] like Figure 1-Figure 3 As shown, when the positioning plate 13 rotates, it can drive the directional hollow shaft 4 connected to it to rotate in the vertical direction. At the same time, an axial gear 6 is fixedly sleeved on the directional hollow shaft 4, thereby driving the axial gear 6 to rotate synchronously, and driving the multiple sets of side gears 7 meshing with the axial gear 6 to rotate synchronously, and the side gear 7 is meshingly connected with an internal gear ring 8, and the internal gear ring 8 is fixed on the base 3 and does not rotate. Therefore, when the axial gear 6 rotates, it can drive the multiple sets of side gears 7 and the coaxially fixed stop cylinder 9 thereon to rotate synchronously and revolve around the directional hollow shaft 4 as the central axis.

[0066] It should be noted that the inner chamber formed between the multiple groups of retaining cylinders 9 is coaxial with the directional hollow shafts 4, and the extruded cables 2 enter the inner chamber through one group of directional hollow shafts 4 and pass through another group of directional hollow shafts 4. When the retaining cylinders 9 rotate and revolve synchronously, the retaining cylinders 9 can be evenly in contact with the cables 2 to provide stable support for the cables 2, and can provide multiple support points for the cables 2, thereby dispersing the pressure and preventing the cables 2 from sagging and deviating from the center.

[0067] Furthermore, when a small amount of eccentricity problem has occurred in the cable 2, multiple groups of positioning cylinders 9 are used to synchronously rotate and revolve in contact with the cable 2, and the force is evenly distributed by utilizing multiple positioning cylinders 9 to correct the cable 2 passing through the inner chamber, thereby ensuring the consistency of the thickness and position of the cable 2 sheath and improving the consistency and reliability of the product.

[0068] At the same time, the retaining tube 9 can adopt a metal structure. In actual use, the contact surface between the retaining tube 9 and the cable 2 is constantly changing, and then the retaining tube 9 is cooled by external natural air. The contact position between the retaining tube 9 and the cable 2 is utilized to cool the cable 2 while adjusting the eccentricity problem of the cable 2, and the cable 2 can be initially shaped due to cooling.

[0069] Based on the embodiment of the deviation correction component, the circulation component includes two groups of vertical support plates 23 fixedly arranged on the base 3, two groups of cooling rollers 24 arranged vertically between the two groups of vertical support plates 23, cooling water sources flowing between the two groups of cooling rollers 24, and two groups of end shafts 26 communicating with the cooling rollers 24 are fixedly connected at both axial ends of the cooling rollers 24, and the end shafts 26 are fixedly rotated on the vertical support plates 23;

[0070] The middle parts of the two groups of cooling rollers 24 are integrally formed with an annular recessed portion 25 , and a space for the cable 2 to pass through is formed between the two groups of annular recessed portions 25 . A water circulation component for providing circulating water to the cooling rollers 24 is provided on the base 3 .

[0071] like Figure 1 , Figure 2 and Figure 4 As shown, after passing through the inner chamber position formed by multiple groups of positioning cylinders 9, it can pass between two groups of cooling rollers 24, and the two groups of cooling rollers 24 include an integrally formed annular recessed portion 25, and the cross-sectional shape of the two groups of annular recessed portions 25 in the vertical direction is the cross-sectional shape of the cable 2. After the cable 2 passes through the position of the annular recessed portion 25, the water source circulating in the cooling roller 24 can cool the cable 2, so that the cable 2 can undergo a pre-cooling process before entering the water tank.

[0072] It should be noted that if a small amount of sheath sagging or eccentricity occurs in the cable 2, the sheath sagging or eccentricity can be adjusted through the movement of multiple groups of positioning cylinders 9. Therefore, after the cable 2 is adjusted, it subsequently passes through two groups of cooling rollers 24 to pre-cool it in time so that it can be shaped after correction.

[0073] In addition, pre-cooling the cable 2 can reduce the sudden drop in temperature of the cable 2 when entering the water tank, avoid cracking of the sheath or uneven internal stress due to too fast cooling speed, and pre-cooling can make the cable 2 initially stabilized before entering the water tank, and the sheath forms a stable initial structure, thereby improving the appearance quality of the cable 2.

[0074] Furthermore, the water circulation assembly includes a water cylinder 21 fixedly connected to the transverse extension plate 10, and a transverse column 20 fixedly connected to the transverse displacement seat 11 is provided on the water cylinder 21. The end of the transverse column 20 away from the transverse displacement seat 11 is fixedly connected to a piston plate 22, and the outer peripheral surface of the piston plate 22 is in sliding contact with the inner wall of the water cylinder 21. The cooling roller 24 and the water tank are both in gas communication with the water cylinder 21.

[0075] The water cylinder 21 is fixedly provided with a water outlet pipe 27, and one end of the water outlet pipe 27 away from the water cylinder 21 is fixedly provided with two sets of branch pipes 28, and one end of the branch pipe 28 away from the water outlet pipe 27 is fixedly provided on the support plate 23 and is in gas communication with one set of end shaft portions 26;

[0076] The water cylinder 21 is also fixedly provided with a water inlet pipe 29, and one end of the water inlet pipe 29 away from the water cylinder 21 is fixedly provided on the water tank. The water tank is also fixedly provided with a water return pipe 30, and one end of the water return pipe 30 away from the water tank is provided on the vertical support plate 23 and is in gas communication with the other set of end shaft portions 26.

[0077] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, driven by the transverse movement assembly, the transverse movement seat 11 can reciprocate in the horizontal direction, wherein the transverse movement seat 11 is fixedly provided with a piston plate 22 through a transverse column 20, and the piston plate 22 is in sliding contact with the water cylinder 21, so that the reciprocating movement of the piston plate 22 can push the water source in the water cylinder 21.

[0078] Among them, when the piston plate 22 moves toward the water cylinder 21, it can drive the water source in the water cylinder 21 to enter the cooling roller 24 through the water outlet pipe 27 and the branch pipe 28 in turn, and let the water source enter the water tank through the cooling roller 24 and the return water pipe 30, so as to replace the water source in the cooling roller 24, so that there is a flowing water source in the cooling roller 24, so as to ensure the continuous cooling of the cable 2.

[0079] At the same time, when the piston plate 22 moves away from the water cylinder 21, it can suck the water in the water tank through the water inlet pipe 29, and then replenish the water into the water cylinder 21, so that the water can enter the water cylinder 21 through the water tank, and enter the cooling roller 24 through the water cylinder 21, and the water can flow into the water tank again through the cooling roller 24.

[0080] It should be noted that a group of one-way valves with opposite valve ports are respectively provided on the water outlet pipe 27 and the water inlet pipe 29. The two groups of one-way valves are provided to limit the flow direction of the water source, so as to enable the water source in the water tank to enter the cooling roller 24 through the water cylinder 21 and to flow back to the water tank again.

[0081] The network wire extrusion method is applied to the network wire extrusion device, comprising the following steps;

[0082] S1, wire extrusion: extrude the cable 2 from the die head of the extruder 1, and pull the cable 2 onto the supporting guide roller 18;

[0083] S2. Change of fulcrum: The supporting guide roller 18 reciprocates in the horizontal direction under the drive of the transverse shifting assembly, thereby dynamically changing the position of the supporting point, evenly distributing the force, and reducing the deformation of the sheath;

[0084] S3, wire correction: the cable 2 enters the inner chamber through the directional hollow shaft 4, and passes through the correction component, and is stably supported and corrected through the revolution and rotation of the stop cylinder 9 to ensure the consistency of the sheath thickness and position;

[0085] S4, cooling and shaping: the cable 2 passes through the cooling roller 24, and the circulating water in the cooling roller 24 is used to preliminarily cool the cable 2 to avoid a sudden drop in temperature when entering the water tank. After pre-cooling, the cable 2 enters the water tank for final cooling to further stabilize the sheath structure and improve the appearance quality of the cable 2.

[0086] like Fig. 9 As shown, in the extruder 1, the cable 2 is extruded from the die head. The extruded cable 2 will be pulled onto the support guide roller 18. The function of the support guide roller 18 is to support the cable 2 just extruded to prevent it from sagging due to gravity. The surface of the support guide roller 18 is smoothed to reduce the friction damage caused by the cable 2 during the passage, thereby maintaining the integrity and quality of the sheath. The free rotation design of the support guide roller 18 reduces friction, helps to protect the sheath of the cable 2, ensures its smooth surface, and avoids defects in the subsequent processing process.

[0087] Driven by the transverse movement component, the support guide roller 18 reciprocates in the horizontal direction. The dynamically changing support point design can evenly distribute the force on the cable 2 and reduce the problem of sheath deformation. By continuously adjusting the position of the support point, the cable 2 can be effectively prevented from being subjected to continuous pressure at a fixed position, thereby reducing the risk of sheath deformation. In addition, the dynamic change of the support point can also alleviate the stress concentration phenomenon and prevent the sheath and internal copper wire from being subjected to excessive mechanical stress.

[0088] The cable 2 enters the inner chamber from the directional hollow shaft 4 and passes through the correction assembly. The correction assembly includes multiple positioning cylinders 9, which can rotate freely and revolve in the vertical direction. The positioning cylinders 9 can stably support and correct the cable 2, thereby ensuring that the cable 2 is evenly supported during the sheath molding process, thereby reducing the eccentricity problem of the sheath. The contact between the positioning cylinders 9 and the cable 2 can disperse the pressure on the cable 2, ensure the consistency of the thickness and position of the sheath, and improve the consistency and reliability of the product. The metal structure of the positioning cylinders 9 can also be cooled by natural air to help the cable 2 remain stable during the adjustment process.

[0089] After the deviation correction, the cable 2 will pass through the cooling roller 24. The cooling water flowing inside the cooling roller 24 will preliminarily cool the cable 2 to reduce the sudden temperature drop of the cable 2 when entering the water tank. This pre-cooling process helps to stabilize the initial structure of the cable 2 and avoid the problem of sheath cracking or uneven internal stress caused by too fast cooling speed. After passing through the cooling roller 24, the cable 2 will further enter the water tank for final cooling. This final cooling step further stabilizes the sheath structure and significantly improves the appearance quality of the cable 2, making it meet higher production standards.

[0090] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
