Description

Technical Field

[0001] This utility model relates to the field of cable processing equipment technology, and in particular to a wrapping frame for a cable braiding machine. Background Technology

[0002] With societal progress and development, and increasing market demands, the performance requirements for cables are becoming increasingly stringent. Cable shielding layers require longitudinal wrapping with aluminum foil and copper foil tape, and the stability of the wrapping frame determines the cable's standing wave stability. In existing technologies, cable braiding machines typically have wrapping frames for supplying and discharging aluminum or copper foil tape. These frames include a support frame with a rotating shaft mounted on it. The rotating shaft has a wrapping disc containing coiled aluminum or copper foil tape. During longitudinal wrapping, the aluminum or copper foil tape is pulled into the longitudinal wrapping die of the cable braiding machine. The rotating disc and shaft rotate under this pulling action to discharge the aluminum or copper foil tape. However, because the tension of the turntable shaft of the tape holder is unstable when it rotates, as the amount of aluminum foil or copper foil tape on the tape turntable gradually decreases, the tape roll changes from a full roll to a half roll, and then to an empty roll, and the tension continuously decreases, requiring constant manual adjustment of the tension; at the same time, when the slices on both sides of the aluminum foil or copper foil tape are uneven, it is impossible to level them manually. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a cable braiding machine wrapping frame that can adjust the tension of the metal wrapping tape and flatten the metal wrapping tape, based on the shortcomings of the existing technology.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a wrapping frame for a cable braiding machine, including a support frame, a turntable shaft mounted on the support frame, and a wrapping turntable for accommodating metal wrapping tape mounted at the front end of the turntable shaft; a tension guiding device and several guide rollers are also mounted on the support frame, and the metal wrapping tape in the wrapping turntable can be discharged after passing through the tension guiding device and the guide rollers; the tension guiding device includes a swing arm shaft, a swing arm, a tension guiding rod, an adjusting rod, a spring seat, and a spring, the swing arm shaft is mounted on the support frame and located above the turntable shaft, the swing arm is mounted at the front end of the swing arm shaft, the tension guiding rod is mounted at the other end of the swing arm, one end of the adjusting rod is connected to the rear end of the swing arm shaft, the spring seat is mounted on the support frame and located above the other end of the adjusting rod, the upper end of the spring is connected to the spring seat, and the lower end of the spring is connected to the other end of the adjusting rod.

[0005] In the above technical solution, the tension guiding device further includes a sliding wheel, a belt positioning seat, and a belt. The sliding wheel is installed at the rear end of the turntable shaft and has an annular groove. The belt positioning seat is installed on the bracket. One end of the belt is connected to the belt positioning seat, and the other end of the belt is connected to the middle of the adjusting rod. The middle of the belt is wound around the annular groove of the sliding wheel and slides in contact with the annular groove.

[0006] In the above technical solution, the bracket is equipped with a first bushing, a first bearing is installed inside the first bushing, and the middle part of the turntable shaft is installed inside the first bearing.

[0007] In the above technical solution, the bracket is equipped with a second bushing, and a second bearing is installed inside the second bushing. The middle part of the swing arm shaft is installed inside the second bearing.

[0008] In the above technical solution, the other end of the adjusting rod is provided with a plurality of spring connecting holes in parallel, and the lower end of the spring is connected to any one of the spring connecting holes.

[0009] In the above technical solution, there are seven optical guide wheels, namely, a first optical guide wheel, a second optical guide wheel, a third optical guide wheel, a fourth optical guide wheel, a fifth optical guide wheel, a sixth optical guide wheel, and a seventh optical guide wheel. The first optical guide wheel is located on the support near the swing arm. The second, third, and fourth optical guide wheels are arranged at the upper end of the support. The fifth, sixth, and seventh optical guide wheels are arranged at the middle of the support and are located below the second, third, and fourth optical guide wheels. The metal strapping in the strapping turntable can be sequentially guided by the first optical guide wheel, the tension guide rod, the second optical guide wheel, the fifth optical guide wheel, the third optical guide wheel, the sixth optical guide wheel, the fourth optical guide wheel, and the seventh optical guide wheel before being led out.

[0010] In the above technical solution, a fixing seat is integrally connected to the end of the bracket away from the tension guiding device, and the fixing seat is provided with a number of fixing holes.

[0011] The beneficial effects of this utility model are as follows: Since a tension guiding device and several guide rollers are installed on the support, the tension of the metal tape in the tape turntable can be adjusted by the tension guiding device during the tape export process, and the metal tape can be flattened by the guide rollers, thereby improving the export stability and quality of the metal tape and increasing manual efficiency. In operation, the cable braiding machine pulls the metal strapping tape outwards, and the tape turntable rotates clockwise continuously. During this process, the spring of the tension guide device pulls the other end of the adjusting rod upwards, giving the other end of the adjusting rod an upward pulling force. The adjusting rod then gives the swing rod and tension guide rod a counterclockwise swinging force through the swing rod shaft. When the tension of the metal strapping tape is too high, the metal strapping tape will pull the swing rod and tension guide rod to swing clockwise, reducing the tension of the metal strapping tape. When the tension of the metal strapping tape is too low, the swing rod and tension guide rod will swing counterclockwise under the action of the spring, increasing the tension of the metal strapping tape, thereby achieving the purpose of adjusting the tension of the metal strapping tape. When the metal strapping tape passes through each guide roller, the guide roller can flatten the metal strapping tape. Attached Figure Description

[0016] The structural and working principles of this utility model will be further described in detail below with reference to the accompanying drawings.

[0017] like Figures 1-4As shown, this utility model is a wrapping frame for a cable braiding machine, including a support 1. A turntable shaft 2 is mounted on the support 1, and a wrapping turntable 3 for accommodating metal wrapping tape is mounted at the front end of the turntable shaft 2. A tension guiding device and several guide rollers 4, 5, 6, 7, 8, 9, and 10 are also mounted on the support 1. The metal wrapping tape 100 in the wrapping turntable 3 can be discharged after passing through the tension guiding device and the guide rollers. The tension guiding device includes a swing arm shaft 11, a swing arm 12, a tension guiding rod 13, and an adjusting rod. 14. Spring seat 15 and spring 16, the swing arm shaft 11 is mounted on the bracket 1 and located above the turntable shaft 2, the swing arm 12 is mounted on the front end of the swing arm shaft 11, the tension guide rod 13 is mounted on the other end of the swing arm 12, one end of the adjusting rod 14 is connected to the rear end of the swing arm shaft 11, the spring seat 15 is mounted on the bracket 1 and located above the other end of the adjusting rod 14, the upper end of the spring 16 is connected to the spring seat 15, and the lower end of the spring 16 is connected to the other end of the adjusting rod 14. The number of optical guide wheels is seven, namely, the first optical guide wheel 4, the second optical guide wheel 5, the third optical guide wheel 6, the fourth optical guide wheel 7, the fifth optical guide wheel 8, the sixth optical guide wheel 9, and the seventh optical guide wheel 10. The first optical guide wheel 4 is located on the support 1 at the end near the swing arm 12. The second optical guide wheels 5, 6, and 7 are arranged at the upper end of the support 1. The fifth optical guide wheel 8, 9, and 10 are arranged in the middle of the support 1, below the second, third, and fourth optical guide wheels 5, 6, and 7. (See [reference needed]). Figure 4 The metal strapping tape 100 in the strapping tape turntable 3 is sequentially guided by the first guide roller 4, the tension guide rod 13, the second guide roller 5, the fifth guide roller 8, the third guide roller 6, the sixth guide roller 9, the fourth guide roller 7, and the seventh guide roller 10 before being led out. The metal strapping tape 100 in this invention is either aluminum foil strapping tape or copper foil strapping tape.

[0018] Because this utility model has a tension guiding device and several guide rollers installed on the bracket 1, the tension of the metal tape 100 in the tape turntable 3 can be adjusted by the tension guiding device during the unloading process, and the metal tape 100 can be flattened by the guide rollers, thereby improving the unloading stability and quality of the metal tape 100 and improving manual efficiency. In operation, the cable braiding machine pulls the metal strapping 100 outwards, and the strapping turntable 3 rotates continuously clockwise. During this process, the spring 16 of the tension guiding device pulls the other end of the adjusting rod 14 upwards, providing an upward pulling force to the other end of the adjusting rod 14. The adjusting rod 14 then provides a counterclockwise swinging force to the swing rod 12 and the tension guiding rod 13 through the swing rod shaft 11. When the tension of the metal strapping is too high, the metal strapping will pull the swing rod 12 and the tension guiding rod 13 to swing clockwise, reducing the tension of the metal strapping 100. When the tension of the metal strapping 100 is too low, the swing rod 12 and the tension guiding rod 13 will swing counterclockwise under the action of the spring 16, increasing the tension of the metal strapping 100, thereby achieving the purpose of adjusting the tension of the metal strapping 100. When the metal strapping 100 passes through each guide roller, the guide roller can flatten the metal strapping. It should be noted that the clockwise and counterclockwise directions in this invention are based on... Figure 1 and Figure 4 For reference.

[0019] like Figures 1-4As shown, the tension guiding device also includes a sliding wheel 17, a belt positioning seat 18, and a belt 19. The sliding wheel 17 is installed at the rear end of the turntable shaft 2 and has an annular groove 171. The belt positioning seat 18 is installed on the bracket 1. One end of the belt 19 is connected to the belt positioning seat 18, and the other end of the belt 19 is connected to the middle part of the adjusting rod 14. The middle part of the belt 19 is wound around the annular groove 171 of the sliding wheel 17 and slides in contact with the annular groove 171. In operation, the cable braiding machine pulls the metal strapping 100 outwards, and the strapping turntable 3 rotates clockwise continuously. During this process, the middle part of the belt 19 maintains sliding contact with the annular groove 171 of the sliding wheel 17, and there is a set friction between them. When the tension of the metal strapping 100 is too high, the metal strapping 100 will pull the swing arm 12 and the tension guide rod 13 to swing clockwise. Then, the swing arm 12 drives the swing arm shaft 11 to rotate clockwise. Next, the swing arm shaft 11 drives the other end of the swing arm 12 to move downwards. Then, the other end of the swing arm 12 lowers the other end of the belt 19, so that the friction between the belt 19 and the annular groove 171 of the sliding wheel 17 is quickly reduced or even eliminated. When the friction decreases rapidly or even disappears, the tape turntable 3 will increase its rotation speed, thereby rapidly reducing the tension of the metal tape 100. When the tension of the metal tape 100 is too low, the rocker arm 12 and the tension guide rod 13 will swing counterclockwise under the action of the spring 16. Then, the rocker arm 12 will drive the rocker arm shaft 11 to rotate counterclockwise. Next, the rocker arm shaft 11 will drive the other end of the rocker arm 12 to move upward at an accelerated speed. Then, the other end of the rocker arm 12 will pull up the other end of the belt 19, causing the friction between the belt 19 and the annular groove 171 of the sliding wheel 17 to increase rapidly. When the friction increases rapidly, the tape turntable 3 will slow down its rotation speed, thereby rapidly increasing the tension of the metal tape 100.

[0020] like Figure 2 and Figure 3 As shown, the bracket 1 is equipped with a first bushing 20, within which a first bearing 21 is installed. The middle portion of the turntable shaft 2 is mounted within the first bearing 21, thus allowing the turntable shaft 2 to rotate more smoothly. The bracket 1 is equipped with a second bushing 22, within which a second bearing 23 is installed. The middle portion of the swing arm shaft 11 is mounted within the second bearing 23, thus allowing the swing arm shaft 11 to rotate more smoothly. The other end of the adjusting rod 14 has multiple spring connecting holes 141 arranged in parallel. The lower end of the spring 16 is connected to any one of the spring connecting holes 141, thus allowing the tension of the spring 16 to be adjusted.

[0021] like Figures 1-4As shown, a fixing seat 24 is integrally connected to the end of the bracket 1 away from the tension guiding device, and the fixing seat 24 is provided with a plurality of fixing holes 241. This utility model, through the fixing seat 24 and its fixing holes 241, enables the bracket 1 to be installed on a cable braiding machine.

[0022] The above description is merely a preferred embodiment of this utility model. Any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical solution of this utility model shall fall within the scope of the technical solution of this utility model.
