DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-2 As shown, in the embodiment of the utility model, a high-speed wrapping machine with a built-in tape reel structure includes a frame 1, a plurality of built-in tape reels 2, a plurality of movable limiting components 3, a plurality of tension feedback guide wheels 4, and a telescopic wire sleeve 5. The frame 1 is rotatably connected to the inside of the wrapping machine, and a driving component 11 is provided at one end of the frame 1. The frame 1 is penetrated by a wire passage 12 along the length direction. A plurality of built-in tape reels 2 are respectively arranged on the inner side walls of the frame 1 opposite to the wire passage 12. A plurality of movable limiting components 3 are respectively arranged on the inner side walls of the frame 1 opposite to the wire passage 12. A plurality of tension feedback guide wheels 4 are located on the tape wrapping path between the corresponding built-in tape reels 2 and the movable limiting components 3 and are fixedly connected to the frame 1. The telescopic wire sleeve 5 is arranged at one end of the frame 1, and the telescopic wire sleeve 5 includes a fixed sleeve 51 and a telescopic sleeve 52, the fixed sleeve 51 is fixedly connected to the frame 1, and the telescopic sleeve 52 is detachably connected to the fixed sleeve 51.

[0028] The two ends of the frame 1 are rotatably connected to the wrapping machine through bearings, and the frame 1 can be driven by the driving component 11 to rotate at high speed in the wrapping machine. The wire passage 12 is used for wire passing, and the wire is wrapped during the wire passing process. The built-in wrapping disk 2 is tension-controlled by the servo motor and the PLC program center, and the tension feedback guide wheel 4 is used to monitor the tension of the wrapping tape and feed back the data to the control center. The movable limit component 3 is used to change the direction of travel of the wrapping tape and the wrapping angle.

[0029] The cable enters from one end of the cable passage 12 and moves to the other end. Driven by the driving component 11, the frame 1 rotates around the cable as a whole. During the rotation process, the tape extends from a number of built-in tape reels 2, bypasses the tension feedback guide wheel 4 and reaches the movable limit assembly 3. After the movable limit assembly 3 changes direction, it is wound around the cable under the action of rotation. In this process, the real-time monitoring value of the tension feedback guide wheel 4 and the tape wrapping condition on the surface of the wire core after wrapping are used to confirm whether the set tension meets the process requirements, and the tension parameters are adjusted online in time according to the actual situation and the remaining amount of tape, thereby realizing the closed-loop control of the wrapping tension.

[0030] The built-in tape reel 2 moves the tape placement reel from the outer end of the frame 1 to its inner end, reducing the distance between the reel and the center of the wire core. Since the tape and the built-in tape reel 2 are the largest units, this setting can reduce the rotation radius of the two, reduce the overall rotational inertia, and increase the production line speed of the equipment.

[0031] A telescopic wire sleeve 5 is designed at the wire core wrapping inlet end. In order to increase the wrapping speed, the overall rotation speed of the frame 1 needs to be increased. As the wrapping speed increases, the shaking degree of the cable will increase, especially the small diameter wire core will shake more during the wrapping process, affecting the production speed and process requirements. The telescopic wire sleeve 5 can adjust the length of the wire sleeve according to cables of different specifications through the cooperation of the fixed sleeve 51 and the telescopic sleeve 52, limit the maximum shaking of the cable without interfering with the wrapping, and improve the stability of the cable wrapping.

[0032] The movable track 31 is located on the side wall of the frame 1, and the guide wheel support 32 can be moved and fixed on the movable track 31. The limiting guide wheel 33 and the guide wheel support 32 can be connected by bolts. When the bolts are not tightened, the limiting guide wheel 33 can be rotated relative to the guide wheel support 32 to adjust the angle. After the bolts are tightened, the limiting guide wheel 33 is fixed on the guide wheel support 32. By adjusting the position of the guide wheel support 32 on the movable track 31 and the relative angle between the limiting guide wheel 33 and the guide wheel support 32, the outlet angle of the wrapping tape after passing through the limiting guide wheel 33 can be controlled, and the position angle of the limiting guide wheel 33 in each movable limiting assembly 3 can be adjusted independently to meet the process requirements of cables of different specifications.

[0033] See also Figure 4 As shown, the guide wheel surface 331 on the limiting guide wheel 33 is used for the tape to pass through the line, and the limiting clamping shoulders 332 at both ends ensure that the tape is limited to both ends of the guide wheel to prevent deviation and slipping. The surface of the guide wheel surface 331 can be designed as a frosted surface with a certain friction force to ensure that the tape does not run out to the sides and does not scratch the tape during the wrapping process.

[0034] A conical transition structure is formed between the guide wheel surface 331 and the limiting shoulder 332 to prevent the tape from encountering a sudden change in the side wall at the limiting shoulder 332, causing the tape to accumulate and twist, and to ensure a smooth transition of the tape.

[0035] See also Figure 1 and Figure 3 As shown, a bearing can be provided on the periphery of the fixed sleeve 51 as a rotation axis, and the telescopic sleeve 52 can slide in the fixed sleeve 51 to adjust the overall length of the telescopic wire sleeve 5. When the position of the telescopic sleeve 52 is adjusted, the telescopic sleeve 52 can be fixed by tightening the fastening bolts 511 on the periphery of the fixed sleeve 51 so that the fastening bolts 511 contact the bottom wall of the positioning slot 521 of the telescopic sleeve 52 to provide a fastening force to prevent the telescopic sleeve 52 from rotating or deviating.

[0036] When the fastening bolt 511 contacts the positioning slot 521, it can provide lateral blocking force and axial friction force to fix the telescopic sleeve 52, but the telescopic sleeve 52 still has the risk of sliding in the axial direction of the fixing sleeve 51. Therefore, a plurality of positioning circular holes 522 are provided in the positioning slot 521, so that the ends of the fastening bolts 511 can be screwed into the positioning circular holes 522, thereby limiting the freedom of the telescopic sleeve 52 in all directions and improving the fastening effect.

[0037] See also Figure 1 and Figure 2 As shown, in order to further improve the stability of cable wrapping, a baffle 6 can be set between the built-in wrapping disc 2 and the movable limit assembly 3, and the wire passage 12 passes through the baffle 6. A telescopic wire sleeve 5 is set at the passing position to limit the shaking of the cable. A perforation can be opened on the baffle 6 for the wrapping tape to pass through.

[0038] The above contents are merely examples and explanations of the structure of the utility model. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the utility model.
