Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cable manufacturing equipment and tooling, and in particular relates to an online continuous longitudinal wrapping equipment for strip materials. Background Technology
[0002] Electrical equipment production lines are undergoing an unprecedented wave of technological transformation, exhibiting a deep integration of high speed, intelligence, green technology, and flexibility. Driven by Industry 4.0 and the "dual carbon" goal, traditional production lines are accelerating their transformation towards digital twins and high speed. For example, high-precision high-speed extruders are gradually replacing older equipment. The high precision of high-speed extruders is mainly reflected in their high production speed and high level of intelligence. As electrical equipment for cable production continues to develop towards high speed and intelligence, corresponding supporting equipment should also improve its adaptability to ensure that when equipment is used in combination with other equipment to meet specific needs, it can also meet the requirements of high speed.
[0003] Some equipment products require longitudinal wrapping of strip materials, and this structure is produced concurrently with the next production process; for example, longitudinally wrapping strip material around a conductor while simultaneously extruding an insulation layer, or longitudinally wrapping strip material around a cable core while simultaneously extruding a non-metallic sheath. These strip materials typically include polyester tape, mica tape, insulating paper, aluminum-plastic film paper, high-strength non-woven fabric, and fiberglass tape. This strip material, when wrapped around the outer layer of the corresponding structure, primarily serves as an insulating or shielding layer. This invention mainly addresses the drawbacks of continuous, non-stop production on high-speed extruders or is used in conjunction with equipment requiring longitudinal wrapping of strip materials; particularly for electrical equipment lines, whose structural dimensions often exhibit small outer diameters and specifications. Therefore, large-length production is frequently required in actual production. This equipment can solve the problem of continuous production when there is a simultaneous need for long-length cable production and longitudinal wrapping, reducing material consumption and production cycle time caused by extruder downtime, thus saving manufacturing costs for enterprises. Utility Model Content

The adjusting component has a central shaft, on which two strip winding wheels are symmetrically mounted. Two locking nuts are symmetrically mounted at both ends of the central shaft. An upper stop bar is provided at the top of the adjusting component, on which two fixed guide wheels are symmetrically mounted.
[0007] Furthermore: the storage component includes a storage box, one end of which is provided with a storage belt conveyor wheel, a servo motor is provided behind the storage belt conveyor wheel, a clamping guide wheel is provided above the storage belt conveyor wheel, and a telescopic cylinder is provided behind the clamping guide wheel.

[0010] Furthermore, the end guide wheel is a V-shaped wheel, which guides the longitudinal wrapping strip to wrap the wire core into a V-shape.
[0011] Furthermore, the transition guide plate is V-shaped with a smooth bottom and a roughness of less than 0.8, mainly to reduce friction and prevent strip breakage from affecting production.
[0012] Furthermore, the length of the transition guide plate extending beyond the flow guide frame is adjustable.

Combined with the pre-stored strip mechanism in the storage box, it can achieve seamless connection between new and old strips and completely eliminate the downtime of traditional reel changing. It has achieved a technological breakthrough of "no stop during reel changing and zero production interruption", ensuring the continuity of long-length cable wrapping production and has significant industrial application value.
[0018] 2. The speed coordination control of the servo motor and the extruder head (initial 2x speed belt storage + subsequent constant speed matching) ensures the dynamic balance between belt supply and consumption, extending the continuous operation time of the production line; the dynamic storage system acts as a buffer unit, reducing the number of downtimes and thus saving losses from start-up and shutdown material discharge, saving manufacturing costs for enterprises and increasing profit margins;
[0019] 3. Modular adjustment components enable three-dimensional adjustment: height adjustable (upper / lower support column sliding lock), horizontal rotation (second locking pin fixed), and roller angle adjustment, adapting to different production line layouts and shortening installation and commissioning time;
[0020] 4. The dual-wheel structure of the storage and conveying wheel, together with the clamping guide wheel and the telescopic cylinder, generates a constant tension force, reduces the belt deviation rate, and prevents the belt from loosening or being overstretched. Attached Figure Description

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figures 1-4 A continuous longitudinal wrapping equipment for strip includes a guiding device for storing and guiding the flow of longitudinally wrapped strip 3, and a feeding device for switching between two stations is provided at the feeding end of the guiding device.
[0028] In this embodiment: the feeding device includes a rotating base 103, on which an adjusting component for vertical telescopic adjustment of height is rotatably mounted. The adjusting component has a central shaft 106, on which two strip winding wheels 107 are symmetrically mounted. Two locking nuts 108 are symmetrically mounted at both ends of the central shaft 106. An upper stop bar 109 is provided at the top of the adjusting component, on which two fixed guide wheels 110 are symmetrically mounted. The adjusting component includes a lower support column 102, within which an upper support column 101 is slidably mounted. A first locking pin 104 is mounted at the top of the lower support column 102. The lower support column 102 and the rotating base 103 are connected by bearings, and the central shaft 106 and the upper support column 101 are connected by bearings. A second locking pin 105 is mounted on the rotating base 103. The feeding device is placed at the feeding end of the guiding device, and then, with the support of the lower support column 102, the upper support column 101 is pulled to the appropriate position. The height is adjusted, and the first locking pin 104 is tightened to fix it. Under the support of the rotating seat 103, the lower support column 102 is rotated, causing the upper support column 101 to rotate accordingly. The strip reel 107 with the longitudinally wrapped strip 3 is aligned with the feed end of the guide device, and the second locking pin 105 is tightened to fix it. Then, under the support of the central shaft 106, the longitudinally wrapped strip 3 is pulled out from the strip reel 107, passes around the fixed guide wheel 110 on the upper stop bar 109, and then the longitudinally wrapped strip 3 is pulled out from the storage strip. The conveyor wheel 203 is inserted into the storage box 202. After the longitudinally wrapped strip 3 on the strip reel 107 is released, the second locking pin 105 is released. Under the support of the rotating seat 103, the lower support column 102 is rotated so that the upper support column 101 rotates accordingly. The strip reel 107 with the longitudinally wrapped strip 3 on the other side is rotated to align with the feed end of the guide device. The end of the new longitudinally wrapped strip 3 is then connected to the exposed end of the longitudinally wrapped strip 3 according to the steps during preparation.
[0029] In this embodiment: the guiding device includes a support base 201, on which a storage component for pre-storing a portion of the longitudinally wrapped strip 3 is provided, and on the storage component a flow guiding component for guiding the longitudinally wrapped strip 3 to flow around the core 4; the storage component includes a storage box 202, one end of which is provided with a storage conveyor wheel 203, a servo motor 204 is provided behind the storage conveyor wheel 203, a clamping guide wheel 205 is provided above the storage conveyor wheel 203, and a telescopic cylinder 206 is provided behind the clamping guide wheel 205; both the storage conveyor wheel 203 and the clamping guide wheel 205 are double-wheel structures, used to apply force tightly against the longitudinally wrapped strip 3; the flow guiding component includes a flow guide frame 207, the discharge end of which is provided with A transition guide plate 210 is provided, with an end guide wheel 209 on one side of the transition guide plate 210. Several guide rods 208 are evenly distributed on the side of the end guide wheel 209 away from the transition guide plate 210. The end guide wheel 209 is a V-shaped wheel, guiding the longitudinally wrapped strip 3 to wrap the wire core 4 into a V-shape. The transition guide plate 210 is V-shaped, with a smooth bottom transition and a roughness of less than 0.8, mainly to reduce friction and prevent strip breakage from affecting production. The length of the transition guide plate 210 extending beyond the guide frame 207 is adjustable. During preparation, the guiding device is placed between the extruder head 5 and the wire feeding frame, allowing the longitudinally wrapped strip 3 to pass through the storage conveyor wheel 203 into the storage box 202 and out through the clamping guide wheel 205. The longitudinally wrapped strip 3, padded under the wire core 4 released from the pay-off frame, passes sequentially around the guide rod 208 on the guide frame 207. Finally, guided by the end guide wheel 209, the longitudinally wrapped strip 3 wraps the wire core 4 into a V-shape and enters the transition guide plate 210. The transition guide plate 210 maintains the V-shape of the longitudinally wrapped strip 3 wrapping the wire core 4 as it enters the extruder head 5. During normal operation, the longitudinally wrapped strip 3 and the wire core 4 are tightly wrapped together. When the extruder head 5 pulls the wire core 4, it simultaneously drives the longitudinally wrapped strip 3 forward. The telescopic cylinder 206 pushes the clamping guide wheel 205 to clamp the longitudinally wrapped strip 3, generating a pulling tension force. Initially, the servo motor 204 drives the storage conveyor wheel 203 to rotate at a speed more than twice the traction speed of the extruder head 5. The storage conveyor wheel 203 pulls the longitudinally wrapped strip 3 on the strip reel 107 into the storage box 202 to quickly store a portion of the longitudinally wrapped strip 3. After completion, the drive speed of the servo motor 204 returns to the same speed as the traction speed of the extruder head 5. When all the longitudinally wrapped strip 3 on the strip reel 107 has been released, the servo motor 204 stops working and connects the end of the new longitudinally wrapped strip 3 to the exposed end of the longitudinally wrapped strip 3 according to the steps during preparation. Then, the servo motor 204 restarts to drive the storage conveyor wheel 203 to rotate, pulling the longitudinally wrapped strip 3 into the storage box 202. During this period, the extruder head 5 uses a portion of the longitudinally wrapped strip 3 pre-stored in the storage box 202 to ensure the continuity of production.
[0030] Working principle: During preparation, first place the guiding device between the extruder head 5 and the feeder frame, then place the feeding device at the feeding end of the guiding device. Next, with the support of the lower support column 102, pull the upper support column 101 to a suitable height and tighten the first locking screw 104 to fix it. With the support of the rotating seat 103, rotate the lower support column 102 so that the upper support column 101 rotates accordingly. Align the strip reel 107 with the longitudinally wrapped strip 3 with the feeding end of the guiding device and tighten the second locking screw 105 to fix it. Then, with the support of the central shaft 106, feed the strip from the feeder... The longitudinal wrapping strip 3 is pulled out from the reel 107, passes around the fixed guide wheel 110 on the upper stop bar 109, and then the longitudinal wrapping strip 3 passes through the storage box 202 from the storage conveyor wheel 203 and passes out from the clamping guide wheel 205. Then the longitudinal wrapping strip 3 is padded under the wire core 4 released by the wire release frame and passes around the guide rod 208 on the guide frame 207 in sequence. Finally, the longitudinal wrapping strip 3 wraps the wire core 4 into a V shape under the guidance of the end guide wheel 209 and enters the transition guide plate 210. The transition guide plate 210 keeps the longitudinal wrapping strip 3 wrapped in the wire core 4 in a V shape and enters the extruder head 5.
[0031] During normal operation, the longitudinally wrapped strip 3 and the wire core 4 are tightly wrapped together. When the extruder head 5 pulls the wire core 4, it simultaneously drives the longitudinally wrapped strip 3 forward. The telescopic cylinder 206 pushes the clamping guide wheel 205 to clamp the longitudinally wrapped strip 3, generating a pulling tension force. Initially, the servo motor 204 drives the storage conveyor wheel 203 to rotate at a speed more than twice the traction speed of the extruder head 5, so that the storage conveyor wheel 203 pulls the longitudinally wrapped strip 3 on the strip reel 107 into the storage box 202, thereby achieving the function of quickly storing a portion of the longitudinally wrapped strip 3. After completion, the driving speed of the servo motor 204 returns to the same speed as the traction speed of the extruder head 5. When all the longitudinally wrapped strip 3 on the strip reel 107 is released... When the servo motor 204 stops working, the end of the longitudinally wrapped strip 3 is exposed. The second locking pin 105 is released. With the support of the rotating seat 103, the lower support column 102 is rotated, causing the upper support column 101 to rotate as well. The strip reel 107 with the longitudinally wrapped strip 3 on the other side is rotated to the feed end of the guide device. The end of the new longitudinally wrapped strip 3 is connected to the exposed end of the longitudinally wrapped strip 3 according to the steps during preparation. Then the servo motor 204 restarts to drive the storage conveyor wheel 203 to rotate, pulling the longitudinally wrapped strip 3 into the storage box 202. During this period, the extruder head 5 pulls and uses a portion of the longitudinally wrapped strip 3 pre-stored in the storage box 202 to ensure the continuity of production.
