Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable processing, in particular to an automatic wrapping device for cable insulation material. BACKGROUND

[0002] As the core carrier of power transmission and signal conduction, the insulation performance of the cable directly determines the operation safety and service life, and the wrapping process of the insulation material is the key link to ensure the insulation effect of the cable. At present, the mainstream cable insulation material wrapping equipment in the industry is mainly the traditional wrapping machine, and its core working principle is: the wrapping equipment (including wrapping head, insulation material unwinding mechanism, etc.) is fixedly arranged, the cable is moved along the axial direction by the traction device, the wrapping equipment synchronously completes the spiral winding of the insulation material (such as insulation tape, mica tape, etc.), and the wrapped cable is wound on the cable reel through the take-up mechanism, realizing continuous wrapping operation.

[0003] The above-mentioned traditional wrapping machine is widely used in large-scale production, but its structural design and working mode determine that it has inherent technical defects: on the one hand, the wrapping logic of the traditional wrapping machine is "fixed equipment and moving cable", the thickness of the insulation layer after wrapping remains uniform, and it is impossible to differentially thicken the specific sections of the cable according to the actual use requirements; on the other hand, in actual application scenarios, some cable sections, such as the vicinity of the cable joint, the wall-penetrating and pipe-penetrating sections, and the stress concentration sections, require higher insulation strength and mechanical protection capability, and it is difficult to meet the local strengthening requirements by relying on the insulation wrapping layer with uniform thickness. If the whole insulation layer is thickened, it will lead to material waste, increase in the self-weight of the cable, and inability to improve the use performance of the key sections. At the same time, for short cables that need to prepare thick insulation layers (such as special equipment connecting wires, test short cables, small internal wiring of electrical appliances, etc.), the traditional wrapping machine needs to continuously wrap long cables and then cut them, and there is a large amount of material loss due to the fact that the cutting waste cannot be reused.

[0004] In addition, if the traditional wrapping machine needs to adjust the insulation thickness, it needs to stop and replace the insulation material specifications or adjust the wrapping parameters, which is cumbersome and cannot realize the gradual thickness control of different sections on the same cable, especially the formation of a shuttle-shaped insulation structure with thin ends and thick middle. The shuttle-shaped insulation structure can reduce the material consumption of non-key sections while ensuring the insulation strength of key sections, and can balance the protection effect and economy. Therefore, there is an urgent need for an automatic wrapping device for cable insulation material that can form a shuttle-shaped insulation structure to solve the technical pain points of the traditional wrapping machine, such as the inability to selectively strengthen the local insulation and the difficulty in flexibly adjusting the thickness of the insulation layer. SUMMARY

[0005] In view of the problems that the traditional wrapping machine cannot selectively strengthen the local insulation and cannot flexibly adjust the thickness of the insulation layer, the present application provides an automatic wrapping device for cable insulation material, and the technical scheme used is: An automatic cable insulation material wrapping device, comprising a walking driving device, a fixed jaw, a moving jaw and a moving frame, the fixed jaw is fixedly arranged at the starting end of the walking driving device, the moving jaw and the moving frame are moved by the walking driving device, the moving frame is located between the fixed jaw and the moving jaw, and a wrapping device is installed on the moving frame; the wrapping device comprises a rotating frame and a driving motor one, the rotating frame is rotatably installed on the moving frame, and the driving motor one is fixedly installed on the moving frame, and the output end thereof is in synchronous transmission connection with the rotating frame; a plurality of rotating plates are rotatably installed on the rotating frame, and a fixed shaft disc is installed on the rotating plate.

[0006] Further, a pair of clamping wheels are arranged on the front side of the wrapping device, and the clamping wheels are moved by a moving driving device installed on the moving frame.

[0008] Further, the fixed shaft disc is provided with a detachable mounting shaft disc, and the insulation material belt disc is installed between the fixed shaft disc and the mounting shaft disc.

[0009] Further, a plurality of friction wheels and tension wheels are rotatably installed on the rotating plate for supporting the insulation material belt.

[0010] Further, a detection sensor is also installed on the rotating plate for detecting whether there is remaining insulation material belt on the insulation material belt disc.

[0011] Further, a box body is arranged on the moving frame, the box body is provided with openings corresponding to the cable at the front and rear ends, and a supporting wheel one is rotatably installed at the opening position of the rear end; a box door is arranged at the rear end of the box body.

[0012] Further, a cable discharging device is also included, the cable discharging device comprises a cable disc, a driving motor two, a mounting frame one and a rotating frame; the cable disc is rotatably installed on the mounting frame one; the driving motor two is fixedly installed on the mounting frame one, and the output end thereof is coaxially fixedly connected with the cable disc; a counterweight is installed on one end of the rotating frame, a supporting wheel two is rotatably installed on the other end of the rotating frame, and the middle part of the rotating frame is rotatably installed on the mounting frame one; an encoder is installed on the mounting frame one for detecting the rotation angle of the rotating frame.

[0013] Further, the cable straightening device is further included, the cable straightening device includes mounting frame two, lower roller one, a plurality of lower roller two and support wheel three are sequentially rotated and installed on the mounting frame two from front to back, the mounting frame two is equipped with the upper roller one and the upper roller two that can be lifted, the upper roller one and lower roller one are oppositely arranged, and the upper roller two and lower roller two are spaced apart.

[0014] Further, the PLC control system is further included for controlling the operation of the whole automatic wrapping device.

[0015] Compared with the prior art, the present application has the following advantages: 1. The cable is fixed, and the reciprocating movement of the moving frame (and the wrapping device thereon) can repeatedly wrap the specific section of the cable, efficiently forming a shuttle-shaped insulation structure with thin ends and thick middle, which can specifically improve the insulation thickness and mechanical protection capability of the key section, solve the technical defects that the traditional wrapping machine can only form a uniform thickness insulation layer and cannot be locally strengthened, and avoid material waste and increased cable weight caused by overall thickening, while balancing protection reliability and use flexibility.

[0016] 2. The reciprocating path and movement frequency of the moving frame (and the wrapping device thereon) can be adjusted to accurately control the thickening amplitude and thickening section length of the shuttle-shaped insulation structure, realizing multi-specification adaptation from slight local thickening to substantial reinforcement without the need to replace equipment or stop adjustment, solving the problem that the thickness adjustment of the traditional wrapping machine is complicated and cannot realize differentiated gradual change of the same cable, and adapting to individualized insulation needs in different fields such as power and communication.

[0017] 3. For long cable local reinforcement scenarios, the shuttle-shaped insulation structure of the present application only increases the amount of insulation material in the key section, and the non-key section maintains the conventional thickness, which can save insulation material consumption and reduce production cost compared with the overall thickening scheme; At the same time, it avoids the problems of increased laying difficulty and increased energy consumption caused by the increase of the overall weight of the cable, maintains the good bending property and installation convenience of the cable under the premise of ensuring the protection performance of the key section, and prolongs the overall service life of the cable. 4. For short cable thick insulation preparation scenarios, the shuttle-shaped insulation structure of the present application directly winds the blank accurately, and cuts the shuttle-shaped insulation structure after wrapping, and the other thickness part is not affected, without cutting waste loss, improving material utilization rate and reducing production cost.

[0018] 5. The present application cooperates with the fixed jaw and the moving jaw to position, and combines the automatic movement of the moving frame (and the wrapping device thereon) driven by the walking driving device to realize automatic winding, which is high in automation, improves production efficiency and wrapping precision; The PLC control system integrates parameter setting, operation monitoring and fault alarm functions, and is convenient to operate.

[0035] As a specific embodiment of the present embodiment, the walking driving device 1 can adopt a rack and pinion driving mode, driven by a motor as a power source to drive the sliding seat to move on the guide rail. The motor and the gear are installed on the sliding seat, the rack is installed on the guide rail, the motor drives the gear to rotate, the gear meshes with the rack to convert the rotary motion into linear motion, realizing the movement of the sliding seat. The moving clamp jaw 3 and the moving frame 4 are respectively installed on the respective sliding seats; the fixed clamp jaw 2 and the moving clamp jaw 3 can adopt a three-jaw centering chuck for clamping the cable.

[0036] As shown in Figures 3-6 , the wrapping device includes a rotating frame 7 and a driving motor 8. The rotating frame 7 is rotatably installed on the moving frame 4 (at the position of the cable through hole), and the driving motor 8 is fixedly installed on the moving frame 4. The output end of the driving motor 8 drives the rotating frame 7 to rotate through a transmission wheel and a transmission belt. A plurality of rotating plates 9 are rotatably installed on the rotating frame 7, and a fixed shaft disc 10 is installed on the rotating plate 9. The fixed shaft disc 10 is provided with a mounting shaft disc 11. A pair of clamping wheels 5 are provided on the front side of the wrapping device, and the clamping wheels 5 are driven to move by the moving driving device 6 installed on the moving frame 4.

[0037] As a specific embodiment of the present embodiment, the moving frame 4 is provided with a box body 401, which surrounds the devices on the moving frame 4 and plays a protective role. The box body 401 is provided with openings corresponding to the cable at the front and rear ends, and a support wheel one 402 is rotatably installed at the opening position of the rear end. The rear end of the box body 401 is provided with a box door.

[0038] As shown in Figure 5 and Figure 7 , the moving driving device 6 includes a reversible screw rod 601, a sliding plate 602 and a driving cylinder 603. The reversible screw rod 601 is installed on the moving frame 4 and is driven to rotate by a motor. The sliding plate 602 is provided in pairs and is slidably installed on the moving frame 4. The sliding plate 602 is threadedly connected with the reversible screw rod 601 and is driven to move by the reversible screw rod 601. Each sliding plate 602 is provided with a driving cylinder 603, and the cylinder body of the driving cylinder 603 is fixedly installed on the sliding plate 602. The output end of the driving cylinder 603 is rotatably installed with a clamping wheel 5. The reversible screw rod 601 drives the pair of sliding plates 602 to move towards each other, and the driving cylinder 603 drives the clamping wheel 5 to move, so as to adjust the distance between the same pair of clamping wheels 5. When the same pair of clamping wheels 5 move close to each other, the cable is clamped to facilitate the wrapping of the insulating material. When the same pair of clamping wheels 5 move away from each other, the cable is loosened.

[0039] As shown in Figures 5-6 and Figures 8-10As shown, the two ends of the rotating plate 9 are fixedly installed with rotating shafts, and are rotatably installed on the rotating frame 7 through the rotating shafts. Three sets of rotating plates 9 are taken as an example for description in the embodiment, and the three sets of rotating plates 9 are circumferentially distributed. A plurality of friction wheels 901 and tension wheels 902 are rotatably installed on the rotating plate 9 (one friction wheel 901 and three tension wheels 902 are taken as an example for description in the embodiment), which are used to support the insulating material belt. Figure 10 As shown, the insulating material belt disc is installed between the fixed shaft disc 10 and the mounting shaft disc 11, and the extended insulating material belt is wound on the cable after passing through the friction wheel 901 and the tension wheel 902. A detection sensor 903 is further installed on the rotating plate 9, which is used to detect whether there is insulating material belt left on the insulating material belt disc. If the insulating material belt is used up, the detection sensor 903 will alarm. Specifically, the detection sensor 903 can adopt a diffuse reflection sensor.

[0040] As a specific implementation of the embodiment, the mounting shaft disc 11 is detachable. During operation, the mounting shaft disc 11 is removed, the insulating material belt disc is placed on the center sleeve of the fixed shaft disc 10, and then the mounting shaft disc 11 is installed on the fixed shaft disc 10. Specifically, the mounting shaft disc 11 and the fixed shaft disc 10 can adopt a plug-in type quick installation connection. The center sleeve of the fixed shaft disc 10 is provided with an L-shaped groove including an axial insertion section and a circumferential clamping section. A positioning rod is fixedly installed on the center shaft of the mounting shaft disc 11. The positioning rod on the center shaft is aligned with the axial section of the L-shaped groove on the center sleeve, is pushed in along the axial direction, and is then rotated to make the positioning rod slide along the circumferential section of the L-shaped groove and be clamped in. The positioning rod is clamped at the end of the L-shaped groove to achieve fixation.

[0041] As shown in the figure, Figure 1 The front side of the fixed jaw 2 is sequentially provided with a cable discharging device 12 and a cable straightening device 13.

[0042] As shown in the figure, Figure 11 The cable discharging device 12 includes a cable disc 1201, a driving motor two 1202, a mounting frame one 1203, and a rotating frame 1204. The cable disc 1201 is rotatably installed on the mounting frame one 1203. The driving motor two 1202 is fixedly installed on the mounting frame one 1203, and the output end is coaxially fixedly connected with the cable disc 1201. A counterweight 1206 is installed on one end of the rotating frame 1204, and a support wheel two 1207 (two support wheels two 1207 are taken as an example for description in the embodiment) is rotatably installed on the other end of the rotating frame 1204. The middle part of the rotating frame 1204 is rotatably installed on the mounting frame one 1203. An encoder 1205 is installed on the mounting frame one 1203, which is used to detect the rotation angle of the rotating frame 1204.

[0043] Under normal circumstances, the two ends of the rotating frame 1204 are in a balanced state. The second drive motor 1202 drives the cable reel 1201 to rotate, and the cable moves through the gap between the two support wheels 1207. When the speed of the cable reel 1201 is too fast, causing too much cable to extend and droop, the rotating frame 1204 will be driven to rotate. After the encoder 1205 detects that the rotation angle of the rotating frame 1204 is too large, the second drive motor 1202 will slow down the speed of the cable reel 1201 and control the speed at which the cable moves out until the two ends of the rotating frame 1204 are balanced again.

[0044] like Figure 12 As shown, the cable straightening device 13 includes a second mounting frame 1308. The second mounting frame 1308 is rotatably mounted from front to back with a lower roller 1301, several lower rollers 1302, and a support wheel 1307. The second mounting frame 1308 also has a second drive cylinder 1305 and a manual height adjustment component 1306. The cylinder body of the second drive cylinder 1305 is fixedly mounted on the second mounting frame 1308, and an upper roller 1303 is rotatably mounted on its output end. The upper roller 1303 and the lower roller 1301 are arranged opposite each other. The manual height adjustment component 1306, taking a threaded lifting component as an example, has an upper roller 1304 rotatably mounted on its moving platform, with the upper roller 1304 and the lower rollers 1302 spaced apart.

[0045] The manual height adjustment component 1306 is manually controlled to adjust the height of the upper roller 1304. The drive cylinder 1305 drives the upper roller 1303 to move down. The upper roller 1303 and the lower roller 1301 work together to limit the cable. Then the cable passes through the upper roller 1304 and the lower roller 1302 to complete the straightening work, and then enters the fixing jaw 2 for fixing.

[0046] Support wheel 1 (402), support wheel 2 (1207), and support wheel 3 (1307) are used to support and guide the movement of the cable, reduce friction, and protect the cable sheath.

[0047] This embodiment also includes a PLC control system, which integrates parameter setting, operation monitoring and fault alarm functions to control the operation of the entire automatic packaging device.

[0048] The working principle of this embodiment is as follows: Before processing the package, the operator sets parameters through the PLC to control parameters such as the moving distance of the moving gripper 3, the thickness of the package, and the length of the reciprocating movement path of the moving frame 4.

[0049] After the cable removed from the cable reel 1201 is straightened by the cable straightening device 13, it passes through the fixed clamp 2 and the moving frame 4 and reaches the moving clamp 3. After the moving clamp 3 clamps the end of the cable, it starts to move under the drive of the walking drive device 1. The moving distance is controlled according to the processing requirements.

[0050] After the moving gripper 3 stops moving, the forward and reverse threaded screw 601 rotates and the drive cylinder 603 is activated, and the clamping wheel 5 clamps the cable. The box door of the box 401 is opened manually, the insulating material reel is installed, and the insulating material tape is wrapped around the cable after passing around the friction wheel 901 and tension wheel 902. Then the drive motor 8 is started, the rotating frame 7 begins to rotate around the cable, and at the same time the walking drive device 1 drives the moving frame 4 to start moving, and the insulating material tape is wrapped around the cable. During the wrapping process, the insulating material reel will rotate on its own, and because the rotating plate 9 can rotate, the rotating plate 9 can drive the insulating material reel to make adaptive angle adjustments when the insulating material tape moves, preventing the wrapping process from getting stuck.

[0051] When wrapping the thickened section, the moving frame 4 moves back and forth. When the moving frame 4 moves to the end of the preset path (near the moving gripper 3), the PLC control system triggers a reverse signal. The moving frame 4 moves in the opposite direction along the original path, moves to a position slightly behind the starting point, and then turns again, moving to a position slightly in front of the end of the preset path. This process is repeated multiple times to repeatedly wrap the same section, gradually increasing the thickness of the insulation layer and forming a spindle-shaped insulation structure. After wrapping is completed, the moving frame 4 continues to move towards the moving gripper 3 to continue wrapping the next section until all cables are wrapped.
