Description

Technical Field

[0001] This invention relates to the field of cable winding technology, specifically to a stranded wire winding machine and winding method for computer cable production. Background Technology

[0002] Currently, in the production of computer cables, the outer surface winding of stranded wires is typically completed using traditional winding equipment. Most of this equipment only has a single winding function. After winding to a preset length, mechanical blades are used to cut the winding film. However, this mechanical cutting method has significant drawbacks: the ends of the cut winding film lack effective fixing measures and are prone to loosening, curling, or even detachment due to subsequent traction of the stranded wire or external forces during storage. This severely affects the cable's insulation performance and structural stability. To compensate for this deficiency, some manufacturers need to manually perform heat welding or tape application on the film ends, which not only increases labor costs but also adds complexity to the process. This not only reduces production efficiency, but also leads to inconsistent film end fixing quality due to the randomness of manual operation, making it difficult to meet the stringent requirements of computer cables for winding precision and consistency. In addition, the coordination between the winding mechanism and the cutting mechanism in traditional equipment is poor, and the cutting action easily disturbs the stranded wires during winding, further affecting the uniformity of the winding layer. The above problems have become key bottlenecks restricting the large-scale and automated production of computer cables. Therefore, it is of great practical significance to develop a special equipment that integrates winding and cutting fixing functions and can achieve synchronous operation. To this end, we propose a stranded wire winding machine and winding method for computer cable production to solve the above technical problems. Summary of the Invention

[0004] As a preferred embodiment of the present invention, the stranded wire winding mechanism includes a frame located on the side of the winding film cutting mechanism. At least four support rollers are provided on the frame, and the support rollers are evenly distributed around the circumference of the frame. A C-shaped plate is rotatably mounted between the four support rollers. A connecting plate is fixedly mounted on the side of the C-shaped plate away from the frame, and a positioning pin is fixedly mounted on the side of the connecting plate away from the C-shaped plate. The inner wall of the C-shaped plate has annularly distributed teeth. A power unit is fixedly mounted on the top of the side of the frame away from the C-shaped plate. The power unit is assembled with a servo motor and a dual parallel shaft reducer, and gears are fixedly mounted on both output shafts of the dual parallel shaft reducer. The gears mesh with the teeth.

[0005] In a preferred embodiment of the present invention, the cutting execution seat is connected to the cutting positioning table via a sliding guide; The cutting positioning table is also provided with a limiting block, which is used to limit the sliding stroke of the cutting execution seat; The cutting divider includes a support base, guide rollers, film roll support, and torsion springs; The support base is symmetrically fixed to the cutting execution base about the central axis of the cutting execution base. The guide roller is rotatably mounted on the support base. The film roll bracket is hinged to the support base. The torsion spring is sleeved on the roller shaft of the guide roller. One end of the torsion spring is fixedly connected to the support base, and the other end of the torsion spring is fixedly connected to the film roll bracket.

[0006] As a preferred embodiment of the present invention, the cutting execution unit includes a mounting base, a column, a cutter arm, a heating wheel, a first positioning bolt, a second positioning bolt, and a tension spring; The mounting base slides on the cutting execution seat, the blade arm is fixedly connected to the mounting base via a column, the heating roller is rotatably mounted on the end of the blade arm, the first positioning bolt is fixedly mounted on the top of the cutting execution seat, the second positioning bolt is fixedly mounted on the bottom of the mounting base, and the tension spring is fixedly mounted between the first positioning bolt and the second positioning bolt.

[0007] As a preferred embodiment of the present invention, the heating roller is arranged toward the winding axis of the strand winding mechanism, and the bottom outer edge of the heating roller contacts the top of the film roll support.

[0008] In a preferred embodiment of the present invention, the driving unit is a driving cylinder, the cylinder body of the driving cylinder is fixed to the cutting positioning table, and the piston rod of the driving cylinder is fixedly connected to the mounting base for driving the mounting base to reciprocate along the cutting execution seat.

[0009] As a preferred embodiment of the present invention, a floating joint is provided between the piston rod of the drive cylinder and the mounting base, and the floating joint is used to compensate for assembly errors.

[0010] As a preferred embodiment of the present invention, the heating roller has an integrated heating element inside.

[0011] As a preferred embodiment of the present invention, the stranded wire winding mechanism and the stretch film cutting mechanism are integrally mounted on a cabinet with casters. The cabinet is equipped with a control module, which is electrically connected to the stranded wire winding mechanism and the stretch film cutting mechanism respectively.

[0012] A winding method for a stranded wire bundle winding machine used in computer cable production includes the following steps: S1. Pass one end of the stranded wire used in computer cable production through the inside of the film roll bracket and fix it to the winding end of the external traction equipment. S2. The external traction equipment pulls the stranded wire used in computer cable production at a uniform speed, and the stranded wire winding mechanism simultaneously wraps the winding film evenly around the outer surface of the stranded wire. S3. After winding is completed, the drive unit pushes the mounting seat along the cutting execution seat to move towards the stranded wire winding area, driving the film roll bracket, the cutter arm and the heating roller to approach the wound stranded wire simultaneously. The heating roller squeezes the film roll bracket to flip horizontally downwards along the guide roller and rests on the top outer surface of the stranded wire used for computer cable production. S4. The external traction equipment stops traction, and the strand winding mechanism continues to evenly wind the film around the outer surface of the strand and the outer two circles of the extruded film roll support. The drive unit continues to push the mounting base to move, and the heating roller begins to roll along the top of the film roll support. During the rolling process, the heating roller uses its own heat to heat and press the ends of the two layers of film wound on the film roll support together, thereby achieving the welding of the film ends and forming a continuous film segment. On the other hand, the high temperature of the heating roller also acts on the cutting end of the film, causing the film to melt and break at the designated position, thus completing the cutting action.

[0013] This invention integrates a stranded wire winding mechanism and a wrapping film cutting mechanism. The driving unit drives the cutting execution seat and the cutting execution unit to slide along the cutting positioning table. With the heating and rolling action of the heating roller, the melting and cutting of the wrapping film and the end welding are completed simultaneously, effectively solving the problem of the film end being easy to loosen after cutting in traditional wrapping machines.

[0014] This invention utilizes a hot-rolling roller to roll and cut the film roll support, which flips downwards and rests on the top outer surface of the stranded wire used in computer cable production. The support of the film roll support forms a temporary film transition structure, providing a stable working reference for subsequent end welding and melting-cutting of the wound film. Simultaneously, by using the film roll support to block the top outer surface of the stranded wire, the hot-rolling roller does not directly contact the surface of the stranded wire during the rolling process, avoiding damage to the insulation layer or internal core of the computer cable caused by the high-temperature hot-rolling roller, and ensuring that the structural integrity and electrical performance of the cable product are not affected.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1 to 8 The technical solution provided by the present invention specifically includes the following embodiments: A stranded wire winding machine for computer cable production includes a stranded wire winding mechanism 100 and a stretch film cutting mechanism 200. The stretch film cutting mechanism 200 includes a cutting positioning table 201, a cutting execution seat 202, a cutting partition 203, a cutting execution part 204, and a drive part 205. The cutting positioning table 201 is fixedly disposed on the side of the stranded wire winding mechanism 100, and the length direction of the cutting positioning table 201 is parallel to the winding operation direction of the stranded wire winding mechanism 100. The cutting execution seat 202 is slidably mounted on the top of the cutting positioning table 201, and the sliding direction of the cutting execution seat 202 is the same as the winding operation direction of the stranded wire winding mechanism 100. The cutting execution seat 202 is connected to the cutting positioning table 201 via a sliding guide. The cutting positioning table 201 is also provided with a limiting block 2011, which is used to limit the sliding stroke of the cutting execution seat 202. The cutting partition 203 is installed on the cutting execution seat 202. The cutting execution part 204 is connected to the side of the cutting execution seat 202 facing the stranded wire winding mechanism 100, and the working end of the cutting execution part 204 extends to the winding working area of ​​the stranded wire winding mechanism 100. The driving part 205 is connected to the cutting execution part 204 for driving the cutting execution seat 202 and the cutting execution part 204 to slide along the cutting positioning table 201. After the computer cable bundle to be processed is passed through the relevant components and the device is started, the bundle winding mechanism 100 is responsible for evenly winding the wrapping film around the outer surface of the bundle, completing the winding operation. During the winding operation, the wrapping film cutting mechanism 200 is in a standby state. The cutting positioning table 201 serves as a base, providing stable support for the entire cutting mechanism. Its length direction is parallel to the winding operation direction to ensure the synchronization of the operation. The cutting execution seat 202 is mounted on the top of the cutting positioning table 201 through a sliding guide and can slide along the winding operation direction. The limit stop 2011 on 1 limits its sliding stroke to prevent excessive sliding. When the stranded wire is wound to the preset requirement, the drive unit 205 starts and cooperates with the cutting execution unit 204 to drive the cutting execution seat 202 and the cutting execution unit 204 to move along the cutting positioning table 201 to the stranded wire winding area. During the movement, the cutting partition 203 moves synchronously with the cutting execution seat 202 to block the stranded wire and cooperates with the cutting execution unit 204 to complete the cutting operation of the wrapping film. The working end of the cutting execution unit 204 extends to the winding work area to ensure cutting accuracy.

[0019] Figure 6 , Figure 7 and Figure 8As shown: The stranded wire winding mechanism 100 includes a frame 101 located on the side of the stretch film cutting mechanism 200. At least four support rollers 102 are provided on the frame 101. The support rollers 102 are evenly distributed around the frame 101. A C-shaped plate 103 is rotatably installed between the four support rollers 102. A connecting plate 104 is fixedly installed on the side of the C-shaped plate 103 away from the frame 101. A positioning pin 105 is fixedly installed on the side of the connecting plate 104 away from the C-shaped plate 103. The inner wall of the C-shaped plate 103 is provided with annularly distributed teeth 106. A power unit 107 is fixedly installed on the top of the side of the frame 101 away from the C-shaped plate 103. The power unit 107 is assembled with a dual parallel shaft reducer via a servo motor. Gears 108 are fixedly installed on both output shafts of the dual parallel shaft reducer. The gears 108 mesh with the teeth 106.

[0020] Specifically, the positioning pin 105 is used to insert and fix the winding film roll. When the servo motor of the power unit 107 starts, the dual parallel shaft reducer transmits power to the two gears 108. Through the meshing transmission between the gears 108 and the teeth 106 on the inner wall of the C-shaped plate 103, the C-shaped plate 103 is driven to rotate stably along the support rollers 102. The four support rollers 102 not only provide circumferential support for the C-shaped plate 103, but also reduce the frictional resistance during its rotation, ensuring smooth rotation. As the C-shaped plate 103 rotates, the connecting plate 104 drives the positioning pin 105 and the winding film roll to make a circular motion around the computer cable production bundle that passes through the central area of ​​the support rollers 102, so that the winding film is wound on the outer surface of the computer cable production bundle with a uniform spiral spacing. At the same time, the external traction equipment pulls the computer cable production bundle at a uniform speed, so that the winding film forms a continuous and uniform spiral winding layer on the surface of the bundle, covering the entire area to be wound of the bundle.

[0021] Body reference Figures 3-6As shown: The cutting partition 203 includes a support base 2031, a guide roller 2032, a film roll support 2033, and a torsion spring 2034. The support base 2031 is symmetrically fixed to the cutting execution base 202 about the central axis of the cutting execution base 202. The guide roller 2032 is rotatably mounted on the support base 2031. The film roll support 2033 is hinged to the support base 2031. The torsion spring 2034 is sleeved on the roller shaft of the guide roller 2032. One end of the torsion spring 2034 is fixedly connected to the support base 2031, and the other end of the torsion spring 2034 is fixedly connected to the film roll support 2033. The cutting execution unit 204 includes a mounting base 2041, a column 2042, a blade arm 2043, a heating roller 2044, a first positioning bolt 2045, a second positioning bolt 2046, and a tension spring 2047. The mounting base 2041 slides on the cutting execution base 202, and the blade arm 2043 passes through... The column 2042 is fixedly connected to the mounting base 2041. The heating roller 2044 is rotatably mounted on the end of the cutter arm 2043. The heating roller 2044 integrates a heating element such as a nickel-chromium heating wire or a ceramic heating tube. The heating roller 2044 is positioned towards the winding axis of the stranded wire winding mechanism 100, and the outer edge of the bottom of the heating roller 2044 contacts the top of the film roll support 2033. The first positioning bolt 2045 is fixedly mounted on the top of the cutting execution seat 202, and the second positioning bolt 2046 is fixedly mounted on the bottom of the mounting base 2041. The tension spring 2047 is fixedly mounted between the first positioning bolt 2045 and the second positioning bolt 2046. The drive unit 205 is a drive cylinder. The cylinder body of the drive cylinder is fixed on the cutting positioning table 201, and the piston rod of the drive cylinder is fixedly connected to the mounting base 2041 for driving the mounting base 2041 to slide back and forth along the cutting execution seat 202.

[0022] When the stranded wire reaches the preset length and is wound, the control module triggers the drive unit 205 to operate. The piston rod of the drive cylinder extends and applies a thrust to the mounting base 2041. Initially, under the elastic connection of the tension spring 2047, the mounting base 2041 drives the cutting execution seat 202 to move along the top of the cutting positioning table 201 towards the stranded wire winding mechanism 100, until it is stopped by the limit stop 2011 along the cutting positioning table 201. After the cutting execution seat 202 is stopped, the support seat 2031 and the cutting partition 203, which are symmetrically fixed at its top, stop moving as a whole. At this time, the drive cylinder of the drive unit 205 continues to apply a thrust, and the mounting base 2041 overcomes the tension spring 2047. The elastic tension of 047 begins to slide along the cutting execution seat 202 towards the strand winding area. The mounting seat 2041 drives the cutter arm 2043 and the rotatably mounted heating roller 2044 at its end to move synchronously via the column 2042. Since the bottom outer edge of the heating roller 2044 is initially in contact with the top of the film roll support 2033, and the heating roller 2044 is set towards the winding axis of the strand winding mechanism 100, as the heating roller 2044 continues to move, its squeezing force on the film roll support 2033 gradually increases, causing the film roll support 2033 to overcome the preload of the torsion spring 2034 and move around the hinge point with the support seat 2031, along the rotatably mounted on the support seat 2031. The guide roller 2032 rotates downwards until it reaches a horizontal position, firmly resting on the top outer surface of the wound stranded wire, providing a stable support surface for subsequent film end welding and cutting. After the film roll support 2033 rotates into position, the control module issues a command, the external traction equipment stops traction, the stranded wire stops moving, while the stranded wire winding mechanism 100 continues to operate, tightly winding the film around the horizontal film roll support 2033 twice, forming two overlapping layers of film on the film roll support 2033, providing a reliable welding surface for the film end welding, and preventing the film from falling off due to weak welding. Then, the drive unit 205 continues to push the mounting base 2041 along... The cutting actuator 202 slides, causing the heating roller 2044 to roll smoothly along the top of the film roll support 2033. At this time, the heating element integrated inside the heating roller 2044, such as a nickel-chromium heating wire or a ceramic heating tube, has been heated to the preset welding and melting temperature. During the rolling process, the heating roller 2044 uses its own high temperature to heat and tightly press the ends of the two layers of wrapping film on the film roll support 2033 together, achieving a firm weld at the ends of the wrapping film and forming a continuous film segment, further ensuring the wrapping and sealing of the stranded wire wrapping film. On the other hand, the high temperature of the heating roller 2044 acts synchronously on the cutting end of the wrapping film, causing the wrapping film to melt at the designated position and accurately complete the cutting action.

[0023] Reference Figure 6As shown: A floating joint is provided between the piston rod of the drive cylinder and the mounting seat 2041. The floating joint is used to compensate for assembly errors. During the process of the drive cylinder pushing the mounting seat 2041 to slide along the cutting execution seat, the floating joint can effectively absorb the angular offset and axial clearance between the piston rod and the mounting seat 2041 caused by assembly accuracy deviation, thermal expansion and contraction of parts or long-term wear. This avoids stress concentration problems caused by hard connection, prevents deformation, breakage and other damage at the connection part of the cylinder piston rod or the mounting seat 2041, and ensures the stability and continuity of power transmission of the drive unit 205. The stranded wire winding mechanism 100 and the stretch film cutting mechanism 200 are mounted on a cabinet with casters. The cabinet contains a control module, which is electrically connected to both the stranded wire winding mechanism 100 and the stretch film cutting mechanism 200. The control module can adjust the winding speed of the stranded wire winding mechanism 100 in real time according to the speed signal of the external traction equipment to ensure that the winding tension of the stretch film is uniform and stable. At the same time, an operation touch screen is provided on the side of the cabinet. Operators can set winding parameters (such as the number of winding layers, film tension, cutting temperature, etc.) and monitor the equipment operation status in real time through the touch screen.

[0024] When this solution is in operation, firstly, the entire device is fixed on a cabinet with casters. The device is started through the control module inside the cabinet to ensure that the stranded wire winding mechanism 100 and the stretch film cutting mechanism 200 are in a power-on ready state. At this time, all components are in the initial reset position. After the operation starts, the first step is to pull the wire through the film roll bracket 2033, and then fix it to the winding end of the external traction equipment. The control module issues a command, and the external traction equipment starts to pull the stranded wire at a constant speed along the winding operation direction. At the same time, the stranded wire winding mechanism 100 starts synchronously, driving the winding film to rotate and evenly wrapping the winding film around the outer surface of the moving stranded wire. This winding method is a conventional technical method, and the specific principle will not be described in detail. When the stranded wire reaches the preset length and is fully wound, the control module triggers the drive unit 205 to operate. The piston rod of the drive cylinder extends and applies a thrust to the mounting base 2041. Initially, under the elastic connection of the tension spring 2047, the mounting base 2041 drives the cutting execution seat 202 to move along the top of the cutting positioning table 201 towards the stranded wire winding mechanism 100, until it is stopped by the limit stop 2011 along the cutting positioning table 201. After the cutting execution seat 202 is stopped, the support base 2031 and the cutting partition 203, which are symmetrically fixed at its top, stop moving as a whole. At this time, the drive cylinder of the drive unit 205 continues to apply a thrust, and the mounting base 2041 overcomes the elastic tension of the tension spring 2047 and begins to slide along the cutting execution seat 202 towards the stranded wire winding area. The mounting base 2041 drives the cutter arm 2043 and the rotatably mounted heating roller 2044 at its end to move synchronously via the column 2042. Since the bottom outer edge of the heating roller 2044 is initially in contact with the top of the film roll bracket 2033 and the heating roller 2044 is set towards the winding axis of the stranded wire winding mechanism 100, as the heating roller 2044 continues to move, its squeezing force on the film roll bracket 2033 gradually increases, causing the film roll bracket 2033 to overcome the preload of the torsion spring 2034 and flip downward around the hinge point with the support base 2031 and along the guide roller 2032 rotatably mounted between the support base 2031 until it flips to a horizontal state and rests steadily on the top outer surface of the wound stranded wire, providing a stable support surface for subsequent film end welding and cutting.

[0025] After the membrane roll support 2033 is rotated into position, the control module issues a command to stop the external traction device and the stranding wire stops moving, while the stranding wire winding mechanism 100 continues to operate, tightly winding the wrapping film two turns around the horizontal membrane roll support 2033, forming two overlapping layers of wrapping film on the membrane roll support 2033. This provides a reliable welding surface for welding at the end of the film, preventing the film from falling off due to weak welding. Then, the drive unit 205 continues to push the mounting base 2041 to slide along the cutting execution base 202, driving the heating roller 2044 along the top of the membrane roll support 2033. As the film rolls smoothly, the heating elements integrated inside the heating roller 2044, such as nickel-chromium heating wires or ceramic heating tubes, have been heated to the preset welding and melting temperature. During the rolling process, the heating roller 2044 uses its own high temperature to heat and tightly press the ends of the two layers of wrapping film on the film roll support 2033 together, achieving a firm weld at the ends of the wrapping film and forming a continuous film segment, further ensuring the wrapping and sealing of the stranded wire wrapping film. On the other hand, the high temperature of the heating roller 2044 acts simultaneously on the cutting end of the wrapping film, causing the wrapping film to melt and break at the designated position, accurately completing the cutting action.

[0026] After the cutting and welding actions are completed synchronously, the control module issues a reset command, and the piston rod of the drive cylinder of the drive unit 205 retracts to relieve the force.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.

The cabinet is equipped with a control module, which is electrically connected to the stranded wire winding mechanism (100) and the stretch film cutting mechanism (200).

10. The winding method of a stranded wire bundle winding machine for computer cable production according to claim 9, characterized in that: The following usage steps are included: S1. Pass one end of the stranded wire used for computer cable production through the inside of the membrane roll bracket (2033) and fix it to the winding end of the external traction equipment; S2. The external traction equipment pulls the stranded wire used in the production of computer cables at a uniform speed, and the stranded wire winding mechanism (100) simultaneously and evenly winds the winding film onto the outer surface of the stranded wire. S3. After winding is completed, the drive unit (205) pushes the mounting base (2041) to move along the cutting execution base (202) towards the stranded wire winding area, driving the film roll support (2033), the cutter arm (2043) and the heating roller (2044) to approach the wound stranded wire simultaneously. The heating roller (2044) squeezes the film roll support (2033) to flip horizontally downward along the guide roller (2032) and rest on the top outer surface of the stranded wire for computer cable production. S4. The external traction device stops traction, and the strand winding mechanism (100) continues to evenly wind the winding film on the outer surface of the strand and the two outer rings of the extruded film roll support (2033). The drive unit (205) continues to push the mounting base (2041) to move, and the heating roller (2044) begins to roll along the top of the film roll support (2033). During the rolling process, the heating roller (2044) uses its own heat to heat and press the ends of the two layers of film wound on the film roll support (2033) together to achieve the welding of the film ends and form a continuous film segment. On the other hand, the high temperature of the heating roller (2044) also acts on the cutting end of the film, causing the film to melt at the designated position and complete the cutting action.
