Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of cable production equipment, and specifically to a wire break protection device and a cable shielding machine. Background Art

[0002] In the field of cable technology, water-blocking cables have good waterproof and electrical properties and are widely used in many fields such as electricity and communications. Most water-blocking cables use a metal wire shield plus an aluminum-plastic composite tape structure to protect the electrical circuits inside the cable by enhancing the water-blocking properties.

[0003] During the production process of water-blocking structure cables, a wire break protection device needs to be installed to prevent the metal wire from breaking during the wire splitting process.

However, if the wire breaks after the metal wire is twisted, the wire break protection device of the shielding machine cannot sense it in time and the equipment will not shut down. It is easy to miss and cause rework, which affects production efficiency and makes the quality of the manufactured cable unqualified. Utility Model Content

[0039] With the widespread use of water-blocking structure cables in the market, it is necessary to ensure the quality inspection and production efficiency of cables during the production process. By installing a wire break protection device at the rear end of the production line such as the metal wire twisting structure and metal belt binding structure of the cable shielding machine, the wire break protection device can be used to identify the breakage of the metal wire or metal belt during the production process of the cable to avoid affecting the quality and production efficiency of the cable.

[0040] In view of this, the wire break protection device of the embodiment of the present application includes an identification structure and a fixed structure. The identification structure includes a fixing part and a sensing part. The fixing part is clamped on the outer peripheral surface of the sensing part. The sensing part has an opening for the cable to pass through. The fixed structure includes a base and a support part. One end of the support part is connected to the base, and the other end of the support part is connected to the fixing part of the identification structure. In other words, the fixed structure supports the identification structure in a suitable position to ensure the stability and reliability of the identification structure during operation. The identification structure is used to detect the production status of the cable in the cable production line, identify the breakage of the metal wire or metal belt in the cable through the identification part, and respond in time when an abnormal situation occurs, thereby improving the production efficiency of the cable and reducing quality hazards and safety risks in the production process.

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] The cable shielding machine provided in the embodiment of the present application is used to realize the shielding work of the cable 50 to ensure the quality and performance of the cable 500. The cable shielding machine includes a metal wire twisting structure, a metal belt binding structure, and a wire break protection device respectively arranged at the rear ends of the metal wire twisting structure and the metal belt binding structure. Among them, the metal wire twisting structure is responsible for twisting the metal wires together to form a shielding layer of the cable 500. The metal belt binding structure is used to bind the metal belt on the cable 500 to further enhance the shielding effect of the cable 500. The wire break protection device plays a role in protecting the cable 500 and preventing wire breakage, ensuring that wire breakage can be detected and handled in time during the production process of the cable 500.

[0044] It should be noted that in the present application example, the wire break protection device at one end of the metal wire twisted structure is connected to the wire break protection device at one end of the metal wire twisted structure by a connecting structure 400. The stability and reliability of the wire break protection are enhanced, and the efficiency and accuracy of the wire break protection are improved. Figure 1 As shown, the connection structure 400 includes a second connection line 410 and a fourth connection member 420 disposed at both ends of the second connection line 410. The second connection line 410 is a main connection member responsible for connecting the two disconnection protection devices to form a whole. The fourth connection member 420 is respectively disposed at both ends of the second connection line 410, and the fourth connection member 420 is connected to the second connection member 123 on the disconnection protection device, thereby achieving the stability and reliability of the entire connection structure 400.

[0045] In some embodiments of the present application, Figure 1 As shown, the identification structure 100 includes a fixing member 110 and a sensing member 120. The fixing member 110 is clamped on the outer peripheral surface of the sensing member 120. The sensing member 120 has an opening 130 for the cable 500 to pass through. The fixing structure 200 includes a base 210 and a supporting member 220. One end of the supporting member 220 is connected to the base 210, and the other end of the supporting member 220 is connected to the fixing member 110 of the identification structure 100.

[0046] The identification structure 100 is used to detect the breakage of the metal wire or metal binding tape during the production process of the cable 500, which affects the production quality and production efficiency of the cable 500. The identification structure 100 includes a fixing member 110 and a sensing member 120. The fixing member 110 is clamped on the outer peripheral surface of the sensing member 120. The fixing member 110 ensures the stability of the sensing member 120 and effectively fixes the position of the sensing member 120. The sensing member 120 has an opening 130 for the cable 500 to pass smoothly during the production process. When the cable 500 passes through the opening 130 of the sensing member 120, if the cable 500 is found to have broken wires, the broken part contacts the sensing member 120 to quickly sense and stop the production operation.

[0047] The fixed structure 200 is used to support the identification structure 100 and provide a stable support. The fixed structure 200 includes a base 210 and a support member 220. The support member 220 connects the base 210 and the identification structure 100 to ensure that the identification structure 100 can work accurately and efficiently. Figure 1 The base 210 may also be provided with an opening for fixing the base 210 to prevent the water-blocking structure cable 500 on the identification production line from moving during the detection process.

[0048] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the fixing member 110 includes a first fixing ring 111, a second fixing ring 112, and a first connecting member 114 connecting the first fixing ring 111 and the second fixing ring 112. Both ends of the first fixing ring 111 and the second fixing ring 112 are bent 113, and the bent 113 is provided with a first opening (not shown in the figure), and the first connecting member 114 passes through the first opening of the first fixing ring 111 and the first opening of the second fixing ring 112 respectively, and the two ends of the first fixing ring 111 are bent and fixedly connected with the two ends of the second fixing ring 112.

[0049] In a possible implementation, the fixing member 110 includes a first fixing ring 111 and a second fixing ring 112, both ends of the first fixing ring 111 and the second fixing ring 112 are bent 113, and first openings are provided on the bent 113 at both ends of the first fixing ring 111 and the second fixing ring 112, and the first connecting member 114 passes through the first openings on the bent 113 at both ends of the first fixing ring 111 and the second fixing ring 112, so that the first fixing ring 111 and the second fixing ring 112 are firmly connected together, so that the fixing member 110 has a function of clamping the identification member. It can be understood that the first fixing ring 111 and the second fixing ring 112 have bent 113 at both ends, and the connection method is simple, which can not only improve the stability of the fixing member 110, but also make the entire identification structure 100 more secure and reliable.

[0050] It should be noted that when the cable 500 does not need to be broken during production, the first fixing ring 111 can be directly disassembled without affecting other parts of the cable shielding machine. The detachable design of the fixing member 110 can adapt to different work requirements and improve the utilization and flexibility of the broken wire protection device.

[0051] In some embodiments of the present application, Figure 2 As shown, the induction member 120 includes a first induction ring 121 and a second induction ring 122, and a second connecting member 123 is further provided on one side of the second induction ring 122. The first induction ring 121 is located on the inner side of the first fixing ring 111, and the second induction ring 122 is located on the inner side of the second fixing ring 112. In this way, the induction member 120 is used to sense the state and change of the cable 500 on the production line. The first induction ring 121 and the second induction ring 122 are connected at both ends and are clamped and fixed by the fixing member 110. The first induction ring 121 is located on the inner side of the first fixing ring 111, and the second induction ring 122 is located on the inner side of the second fixing ring 112. A second connecting member 123 is further provided on the second fixing ring 112. The second connecting member 123 is used to connect the induction ring with other equipment or systems to realize the transmission of relevant information on the breakage of the metal wire or metal binding belt in the production process of the cable 500.

[0052] In some embodiments of the present application, Figure 1 As shown, the control structure 300 is also included, and the control structure 300 includes a switch, a third connection member 310, and a first connection line 320 for connecting the switch and the third connection member 310. The third connection member 310 is connected to the second connection member 123 on the second induction ring 122, so that the control structure 300 controls the identification structure 100.

[0053] In a possible implementation, the control structure 300 is used to accurately control the identification structure 100 to ensure the stability and safety of the cable 500 during production. The control structure 300 includes a switch (not shown in the figure), a third connection member 310, and a first connection line 320. One end of the third connection member 310 is connected to the first connection line 320, the other end of the first connection line 320 is connected to the switch, and the other end of the third connection member 310 is connected to the second connection member 123 on the second induction ring 122. In the embodiment of the present application, the third connection member 310 can be a metal clip, and one end of the third connection member 310 can be clamped on the second connection member 123 on the second induction ring 122.

[0054] In another possible implementation, a plurality of line break protection devices may be provided on the production line, and two adjacent line break protection devices are connected via a connection structure 400. A fourth connection member 420 is provided at both ends of the second connection line 410 of the connection structure 400. The fourth connection member 420 may be a metal clip. The fourth connection member 420 may be clamped on the second connection member 123 on the second induction ring 122 to connect the two line break protection devices to form a whole. The third connection member 310 of the control structure 300 may be clamped on the fourth connection member 420 on the second connection member 123 of one of the line break protection devices.

[0055] It is understandable that the switch of the control structure 300 is turned on, and the control current is transmitted to the induction loop to form a current closed circuit using the first connecting wire 320, the third connecting member 310 and the second connecting member 123. When the metal wire and the metal binding belt of the cable 500 on the production line are broken, they come into contact with the induction loop, causing a short circuit to stop the operation of the production line, and the breakage of the cable 500 is discovered in time.

[0056] In some embodiments of the present application, Figure 1 As shown, the side of the second fixing ring 112 facing away from the second induction ring 122 is connected to the support member 220 of the fixing structure 200. It can be understood that the second fixing ring 112 and the support member 220 of the fixing structure 200 are connected as a whole, reducing the risk of failure caused by loose or unstable connection between components. The possibility of structural deformation or displacement caused by vibration or external force is effectively prevented, which is conducive to enhancing the structural stability of the line breaking protection device.

[0057] In some embodiments of this application, please continue to refer to Figure 1 The support member 220 includes a fixed column 221 and an adjusting column 222. The fixed column 221 has a cavity inside, and the cavity is used to accommodate the adjusting column 222, so that the adjusting column 222 is slidably connected in the cavity of the fixed column 221. One end of the fixed column 221 is slidably connected to the adjusting column 222, and the other end of the fixed column 221 is connected to the base 210.

[0058] In a possible implementation, the support member 220 can stably support the identification structure 100, and the support member 220 can also flexibly adjust the height according to the actual needs of the production line. The support member 220 includes a fixed column 221 and an adjustment column 222, wherein one end of the fixed column 221 is connected to the base 210, and is used to support the adjustment column 222 and the identification structure 100. The interior of the fixed column 221 has a cavity for accommodating the adjustment column 222, and the adjustment column 222 is slidably connected to the fixed column 221. By sliding in the cavity of the fixed column 221, the adjustment column 222 can adjust the length of the fixed column 221 as needed, thereby achieving the adjustment of the length of the entire support member 220.

[0059] In some embodiments of the present application, Figure 1 As shown, the fixing structure 200 further includes a fastener 223, which is used to fix the adjusting column 222 and the fixing column 221 so that the adjusting column 222 and the fixing column 221 are tightly connected to prevent the adjusting column 222 and the fixing column 221 from loosening or shifting during use.

[0060] In some embodiments of the present application, the identification structure 100 further includes a first insulating block 140 and a second insulating block 150. The first insulating block 140 is located between the first fixing ring 111 and the first induction ring 121, and the second insulating block 150 is located between the second fixing ring 112 and the second induction ring 122.

[0061] It is understandable that the first insulating block 140 disposed between the first fixed ring 111 and the first induction ring 121, and the second insulating block 150 disposed between the second fixed ring 112 and the second induction ring 122 in the identification structure 100 can enhance the safety and reliability of the identification structure 100. It effectively prevents other metal materials other than the cable 500 from contacting the induction element 120 and causing a circuit breaker. The electrical isolation between the fixed ring and the induction ring is achieved through the first insulating block 140 and the second insulating block 150, providing a strong guarantee for the stable operation of the cable 500 production line.
