Description

Technical Field

[0001] This application relates to the technical field of shielded wire production equipment, and specifically relates to a pre-twisting device for a cable braided mesh. Background Art

[0002] A shielded wire is a wire with a conductor wrapped around its exterior. The wrapped conductor is called a shielding layer, which is generally a braided copper mesh or copper foil (aluminum). The shielding layer needs to be grounded, and external interference signals can be introduced into the ground by this layer.

[0003] Before using a shielded cable, it is usually necessary to process the shielding layer at its end, that is, to separate the metal wire braided shielding layer at its end from the wire core, and twist the separated metal wire bundles that make up the shielding layer into a single wire rope.

[0004] The existing production process is that a cable conveying device conveys the shielded cable that has been brushed and dispersed to a pre-treatment device, and the pre-treatment device performs a certain combing and orientation adjustment on the brushed and dispersed metal wires so as to enter the twisting device for processing later. However, the existing pre-treatment device cannot completely separate the wire core and the dispersed shielded metal wires, and manual separation and combing are required during the conveying process.

[0005] Therefore, it is necessary to provide a pre-twisting device for a cable braided mesh to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute prior art. Summary of the Invention

[0007] Based on the above problems existing in the prior art, the problem to be solved by this application is: to provide a pre-twisting device for a cable braided mesh, which solves the problem that the wire core and the dispersed shielded metal wires cannot be separated.

[0008] The technical solution adopted by this application to solve its technical problems is: a pre-twisting device for a cable braided mesh, including a moving platform and a dispersion mechanism; the moving platform is located on one side of the cable conveying device, and the dispersion mechanism is slidably connected to the moving platform;

[0009] The dispersion mechanism includes a base and a separation plate. One end of the base is slidably connected to the moving platform. A connecting seat is fixedly installed on the top of the base, and the separation plate is fixedly installed at the end of the connecting seat away from the base; thus, the separation plate cooperates with the later movement of the moving platform and the base to separate the wire core and the metal wire, so that the angle between the wire core and the metal wire is close to a right angle.

[0010] Further, the separation plate is an L-shaped plate, and the short side plate of the separation plate is close to the side of the cable conveying device.

[0011] Furthermore, the evacuation mechanism further includes a combing and sweeping wheel. An opening groove is formed in the end face of the base table. A servo motor is arranged inside the opening groove. The output end of the servo motor is fixedly connected with a driving wheel. The other end of the base table far from the moving platform is installed with a rotating shaft through a bearing. The rotating shaft is located at the opening groove, and one end is located outside the base table and fixedly connected with the combing and sweeping wheel. The combing and sweeping wheel is located below the separation plate. A driven wheel is fixedly connected to the side surface of the rotating shaft located in the opening groove. The side surface of the driving wheel is connected with the driven wheel through a belt.

[0012] Thus, the motor controls the rotation of the driven wheel through the driving wheel, so that the rotating shaft drives the combing and sweeping wheel to rotate, thereby realizing the brushing and spreading of the metal wire.

[0013] Furthermore, the moving platform includes a slide rail seat and a fuselage. The bottom end of the fuselage is a matching mechanism with the slide rail. An electric push rod is fixedly connected to the rear side of the fuselage. A rotating motor is arranged inside the top end of the fuselage. The output end of the rotating motor is fixedly connected with a gear. A rack is installed inside the fuselage through a sliding connection. The tooth surface of the gear meshes with the rack.

[0014] A clamping groove is formed in the end face of the connecting seat. The clamping groove and the separation plate are not on the same side. The clamping groove is clamped with the rack.

[0015] Thus, the electric push rod controls the front-back movement of the fuselage on the slide rail seat. The rotating motor controls the rotation of the gear, and further controls the up-down movement of the rack at the fuselage. Further, the base table is driven to move up and down in front of the fuselage through the connecting seat. Further, the combing and sweeping wheel is controlled to perform a square-shaped displacement on the vertical plane. When the fuselage moves forward, the combing and sweeping wheel is placed below the metal wire and the wire core. As the base table moves up, the combing and sweeping wheel adjusts the metal wire from a horizontal state to a vertical state. Subsequently, the fuselage moves backward, so that the combing and sweeping wheel is separated from the metal wire and the wire core. Since the wire core has good bending resistance, the wire core is located below the metal wire. Finally, the base table moves down, the combing and sweeping wheel does not contact the metal wire and the wire core, and the lower side of the separation plate contacts the wire core and presses the wire core, so that the included angle between the wire core and the metal wire is close to a right angle.

[0016] Furthermore, the combing and sweeping wheel is an I-shaped wheel. Combing teeth are uniformly arranged on the outer side of the straight cylinder of the combing and sweeping wheel. The combing teeth are made of silica gel material, so as to reduce the wear on the metal wire.

[0017] Further, a carding member is fixedly installed at the top end of the separation plate. One end of the carding member extends out of the side of the separation plate away from the fuselage, and a Y-shaped groove is formed on the end face of the carding member. When the separation plate presses the wire core to a horizontal state, the fuselage moves forward, enabling the metal wire to enter the Y-shaped groove. Subsequently, after the base moves upward, the carding member combs the metal wire. At this time, the carding wheel does not rotate, and the wire core is pushed to rotate upward. Then the fuselage moves backward, separating the carding member from the metal wire and the carding wheel from the wire core. Due to the bending resistance of the wire core, the wire core rebounds. The downward movement of the base drives the lower side of the separation plate to contact the wire core, once again making the angle between the wire core and the metal wire close to a right angle.

[0018] The beneficial effects of this application are as follows: A cable braided net twisting pretreatment device provided by this application, by providing a separation plate, the separation plate cooperates with the later movement of the moving platform and the base to separate the wire core and the metal wire, making the angle between the wire core and the metal wire close to a right angle, thereby solving the problem that the wire core and the scattered shielding metal wire cannot be separated.

[0019] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. The following will refer to the drawings to further elaborate on this application in detail. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] As Figures 1-4 shown, the present application provides a cable braided mesh twisting pretreatment device, which is applied to the production of shielded wires, and includes a mobile platform 1 and an evacuation mechanism 2; the mobile platform 1 is located on one side of the cable conveying device, and the evacuation mechanism 2 is slidably connected to the mobile platform 1;

[0032] Referring to Figure 1 , the evacuation mechanism 2 includes a base 21 and a separation plate 27. One end of the base 21 is slidably connected to the mobile platform 1, a connecting seat 22 is fixedly installed on the top of the base 21, and the separation plate 27 is fixedly installed at one end of the connecting seat 22 away from the base 21; thus, the separation plate 27 cooperates with the later movement of the mobile platform 1 and the base 21 to separate the wire core and the metal wire, so that the angle between the wire core and the metal wire is close to a right angle.

[0033] Referring to Figure 2 , Figure 3 , the separation plate 27 is an L-shaped plate, and the short side plate of the separation plate 27 is close to the side of the cable conveying device.

[0034] The evacuation mechanism 2 further includes a sweeping wheel 26. An opening groove 211 is formed in the end face of the base 21. A servo motor is arranged inside the opening groove 211. The output end of the servo motor is fixedly connected with a driving wheel 23. The other end of the base 21 away from the moving platform 1 is installed with a rotating shaft 25 through a bearing. The rotating shaft 25 is located at the opening groove 211, and one end is located outside the base 1 and fixedly connected with the sweeping wheel 26. The sweeping wheel 26 is located below the separation plate 27. A driven wheel 24 is fixedly connected to the side surface of the rotating shaft 25 located inside the opening groove 211. The side surface of the driving wheel 2 is connected with the driven wheel 24 through a belt.

[0035] Thus, the motor controls the rotation of the driven wheel 24 through the driving wheel 23, so that the rotating shaft 25 drives the sweeping wheel 26 to rotate, thereby realizing the brushing and spreading of the metal wire.

[0036] Refer to Figure 1 、 Figure 4 The moving platform 1 includes a slide rail seat 11 and a fuselage 12. The bottom end of the fuselage 12 and the slide rail seat 11 are a matching mechanism. An electric push rod is fixedly connected to the rear side of the fuselage 12. A rotating motor 121 is arranged inside the top end of the fuselage 12. The output end of the rotating motor 121 is fixedly connected with a gear 122. A rack 123 is installed inside the fuselage 12 through a sliding connection. The tooth surface of the gear 122 meshes with the rack 123.

[0037] A clamping groove 221 is formed in the end face of the connecting seat 22. The clamping groove 211 and the separation plate 27 are not on the same side. The clamping groove 221 is clamped with the rack 123.

[0038] Its working process is as follows: The electric push rod controls the fuselage 12 to move back and forth on the slide rail seat 11. The rotating motor 121 controls the rotation of the gear 122, and then controls the up and down movement of the rack 123 at the fuselage 12. Then, the base 21 is driven to move up and down in front of the fuselage 12 through the connecting seat 22. Then, the sweeping wheel 26 is controlled to perform a square-shaped displacement on the vertical plane. When the fuselage 12 moves forward, the sweeping wheel 26 is placed below the metal wire and the wire core. As the base 21 moves up, the sweeping wheel 26 adjusts the metal wire from a horizontal state to a vertical state. Subsequently, the fuselage 12 moves backward, so that the sweeping wheel 26 is separated from the metal wire and the wire core. Since the wire core has good bending resistance, the wire core is located below the metal wire. Finally, the base 21 moves down, the sweeping wheel 26 does not contact the metal wire and the wire core, and the lower side of the separation plate 27 contacts the wire core and presses the wire core, so that the included angle between the wire core and the metal wire is close to a right angle.

[0039] Among them, the sweeping wheel 26 is an I-shaped wheel. Comb teeth 261 are evenly arranged on the outer side of the straight cylinder of the sweeping wheel 26. The comb teeth 261 are made of silica gel material, so as to reduce the wear on the metal wire.

[0040] Embodiment 2: Further optimization is proposed on the basis of Embodiment 1. Specifically:

[0041] Reference Figure 5 , a carding member 271 is fixedly installed at the top end of the separation plate 27. One end of the carding member 271 extends out of the side of the separation plate 27 away from the fuselage 12, and a Y-shaped groove 272 is formed on the end face of the carding member 271; when the separation plate 27 presses the wire core to a horizontal state, the fuselage 12 moves forward, so that the metal wire enters the Y-shaped groove 272. Then, after the base 21 moves upward, the carding member 271 combs the metal wire. At this time, the carding wheel 26 does not rotate, and the wire core is pushed to rotate upward; then the fuselage 12 moves backward, so that the carding member 271 is separated from the metal wire, and the carding wheel 26 is separated from the wire core. Due to the bending resistance of the wire core, the wire core rebounds, and the downward movement of the base 21 drives the lower side of the separation plate 27 to contact the wire core, and the included angle between the wire core and the metal wire is close to a right angle again.

[0042] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
