Description

Technical Field

[0001] The present invention relates to the technical field of cable production, and more specifically, it relates to an aluminum foil longitudinal wrapping device suitable for cables. Background Art

[0002] In the technical field of power cable processing, the process of longitudinally wrapping aluminum-plastic tape to bond polyethylene inner sheath or flame-retardant polyolefin inner sheath as a waterproof isolation sleeve has been widely used. In the prior art, cable sheath processing equipment usually includes a longitudinal wrapping horn die, a wire stabilizing die, a sizing die and a thermal control device. The core technical route is "progressive deformation of three-stage dies + thermal control bonding and shaping": the aluminum-plastic tape is first preliminarily deformed from a flat shape to a tubular shape by the longitudinal wrapping horn die, then gradually reduced in diameter to the designed size through the wire stabilizing die and the sizing die, and finally the edge film of the aluminum-plastic tape is heated by a hot air blower to achieve bonding and shaping. However, there are still certain defects in the process of controlling the deformation of the aluminum-plastic tape by the horn die and wrapping it around the cable:

[0003] When the horn die guides the aluminum-plastic tape, the aluminum-plastic tape enters from the larger-diameter end of the horn die and is extruded and deformed in the gradually shrinking die cavity, and finally wrapped around the cable. This method relies on the shape of the horn die to force the aluminum-plastic tape to deform. During the wrapping process of the horn die, the extrusion pressure received by the aluminum-plastic tape at different positions in the die cavity changes greatly. The extrusion pressure is large near the inner wall of the die cavity, while the central area is relatively small. This easily leads to uneven deformation of the aluminum-plastic tape, and it is easy to appear wrinkles or excessive stretching. Moreover, the aluminum-plastic tape has a low degree of fit with the outer contour of the cable after being deformed by the horn die, and subsequent adjustment is required through the wire stabilizing die and the sizing die step by step. Summary of the Invention

[0004] The present invention provides an aluminum foil longitudinal wrapping device suitable for cables to solve the above technical problems.

[0005] The present invention provides an aluminum foil longitudinal wrapping device suitable for cables, which includes a frame and a unwinding rack arranged on the top of the frame. The unwinding rack is wound with a cable and an aluminum-plastic tape. A reciprocating longitudinal wrapping mechanism is arranged on the top of the frame through a workbench. The reciprocating longitudinal wrapping mechanism includes two sets of longitudinal wrapping components for pushing the aluminum-plastic tape to gradually deform and wrap along the outer contour of the cable and be distributed left and right, and a control component for controlling the reciprocating movement of the longitudinal wrapping components. A hot pressing mechanism for hot air heating and extrusion bonding of the longitudinally wrapped aluminum-plastic tape is arranged on the front side of the longitudinal wrapping component.

[0006] A cleaning mechanism is arranged on the front side of the hot pressing mechanism. An extruder head is fixedly installed on the top of the frame and is located in front of the cleaning mechanism. The cleaning mechanism includes a brushing component for brushing and removing impurities on the outer surface of the cable before entering the extruder head, and two sets of traction driving components for traction driving the brushing component and distributed left and right to cooperate with the corresponding longitudinal wrapping components to reciprocate.

[0007] The cleaning mechanism further includes an air guiding pipe for connecting the hot pressing mechanism and the brush assembly. The air guiding pipe guides the hot air used by the hot pressing mechanism to heat the aluminum-plastic tape to the brush assembly for auxiliary cleaning and impurity discharge.

[0008] Further, the two longitudinal wrapping assemblies are symmetric left and right and are arranged in a staggered manner in the front-back direction. The longitudinal wrapping assembly includes a sliding plate that slides through the workbench up and down and a telescopic rod fixedly installed at the top of the sliding plate. A roller is rotatably installed at one end of the telescopic rod close to the center of the workbench.

[0009] Further, the control assembly includes a cylinder fixedly installed at the bottom of the workbench and a connecting plate fixedly installed at the output end of the cylinder and connected to the left and right sliding plates. A chute is opened at the rear side of the fixed section of the telescopic rod, and a spring telescopic rod that is slidably connected in the chute is fixedly installed at the rear side of the telescopic section of the telescopic rod.

[0010] Further, a fixing plate is fixedly installed at the top of the workbench. A control groove is opened at the front side of the fixing plate. The telescopic section of the spring telescopic rod is slidably connected in the control groove.

[0011] Further, the hot pressing mechanism includes a hot air cover fixedly installed at the top of the workbench, and a hot air pipe is fixedly installed at the top of the hot air cover.

[0012] Further, the brush assembly includes a dust collection box fixedly penetrating the workbench. Rotating shafts are rotatably penetrated through the left and right inner walls of the dust collection box, and soft brushes are fixedly installed at one end of the two rotating shafts close to each other.

[0013] Further, the traction drive assembly includes a fixed seat fixedly installed at the top of the workbench. A plurality of installation grooves are opened at the rear side of the fixed seat. A rack is fixedly installed at the rear side of the installation groove through a return spring. A gear that meshes with the corresponding rack is fixedly sleeved at one end of the rotating shaft away from the soft brush. The rack is in an L shape, and teeth are opened at the top of the horizontal section of the rack.

[0014] Further, a fixed pulley is fixedly installed at the top of the workbench. A traction rope is wound around the outside of the fixed pulley. A traction frame is fixedly installed at the top of the telescopic rod. The two ends of the traction rope are respectively connected to the traction frame and the rack.

[0015] Further, the control groove includes a lower check section located at the lower right of the fixing plate. An enclosing section and an upper check section are sequentially connected above the lower check section. The enclosing section is arc-shaped, and the inner arc diameter of the enclosing section coincides with the diameter of the cable. A return section is commonly connected between the upper check section and the lower check section.

[0016] Further, through holes that penetrate through the front and back and are used for passing the cable are opened in the middle of the hot air cover and the dust collection box. The air guiding pipe is fixedly installed between the hot air cover and the dust collection box.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. In this application, at the initial stage of coating, the aluminum-plastic tape is preliminarily fitted to the outer contour of the cable with the help of the arc-shaped guide frame. Subsequently, through the design that the contour of the arc section of the control groove is consistent with the outer diameter of the cable, when the telescopic section of the spring telescopic rod moves in the coating section of the control groove, it will drive the telescopic rod and the roller to move strictly along the outer contour of the cable. This enables the aluminum-plastic tape to closely fit the surface of the cable when the roller pushes the aluminum-plastic tape, uniformly wrapping the cable from all angles and avoiding problems such as loose fitting and excessive gaps.

[0019] 2. In this application, hot air is guided into the dust collection box through the air duct and blown downward. On the one hand, the hot air can make the impurities on the surface of the cable easier to detach, enhancing the cleaning effect; on the other hand, the flow of the hot air can blow the impurities swept by the brush downward and discharge them through the bottom of the dust collection box, playing an auxiliary role in discharging impurities, thereby realizing the recycling of the hot air of the hot pressing mechanism and achieving the efficient utilization of energy.

Detailed implementation mode

[0028] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed so that those skilled in the art can better understand and thus implement the subject matter described herein. Changes can be made to the functions and arrangements of the elements discussed without departing from the scope of protection of the content of this specification. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0029] Refer to Figure 1 and Figure 2 As shown in FIGS. and, in this embodiment, an aluminum foil longitudinal wrapping device applicable to cables is proposed, which includes a frame 1 and an unwind rack 2 arranged on the top of the frame 1. A cable 3 and an aluminum-plastic tape 4 are wound on the unwind rack 2. A reciprocating longitudinal wrapping mechanism 5 is arranged on the top of the frame 1 through a workbench 8. A tape stabilizer 9 and an extrusion machine head 11 located in front of the workbench 8 are fixedly installed on the top of the frame 1. The tape stabilizer 9 is located behind the workbench 8 and is used to guide the aluminum-plastic tape 4. A wire stabilizer 10 and a plurality of arc guiding frames 12 are fixedly installed on the top of the workbench 8. The arc guiding frames 12 are located behind the reciprocating longitudinal wrapping mechanism 5 and are used to guide the aluminum-plastic tape 4 to gradually deform. The wire stabilizer 10 is located behind the arc guiding frames 12 and is used to guide the cable 3.

[0030] Refer to Figure 2 、 Figure 3 and Figure 5, the reciprocating longitudinal wrapping mechanism 5 includes two sets of longitudinal wrapping components 51 for pushing the aluminum-plastic tape 4 to gradually deform and wrap along the outer contour of the cable 3 and be distributed left and right, and a control component 52 for controlling the reciprocating movement of the longitudinal wrapping components 51. The two sets of longitudinal wrapping components 51 are symmetric left and right and are arranged in a staggered manner in the front-back direction. The longitudinal wrapping component 51 includes a sliding plate 511 that slides through the workbench 8 up and down, and a telescopic rod 512 fixedly installed on the top of the sliding plate 511. A roller 513 is rotatably installed at one end of the telescopic rod 512 close to the center of the workbench 8.

[0031] Refer to Figure 2 , Figure 3 and Figure 5 , the control component 52 includes a cylinder 521 fixedly installed at the bottom of the workbench 8 and a connecting plate 522 fixedly installed at the output end of the cylinder 521 and connected to the left and right sliding plates 511. A chute 523 is opened at the rear side of the fixed section of the telescopic rod 512, and a spring telescopic rod 524 slidably connected in the chute 523 is fixedly installed at the rear side of the telescopic section of the telescopic rod 512.

[0032] Refer to Figure 2 , Figure 3 , Figure 5 and Figure 7 , a fixing plate 526 is fixedly installed on the top of the workbench 8. A control groove 525 is opened at the front side of the fixing plate 526. The telescopic section of the spring telescopic rod 524 is slidably connected in the control groove 525.

[0033] Refer to Figure 7 , the control groove 525 includes a lower check section 5251 located at the lower right of the fixing plate 526. The upper part of the lower check section 5251 is sequentially connected with a wrapping section 5252 and an upper check section 5253. The wrapping section 5252 is arc-shaped, and the inner arc diameter of the wrapping section 5252 is consistent with the diameter of the cable 3. A reset section 5254 is commonly connected between the upper check section 5253 and the lower check section 5251. Transition arc surfaces are opened at the connection between the lower check section 5251 and the wrapping section 5252 and at the connection between the upper check section 5253 and the reset section 5254.

[0034] During specific use, the cable 3 and the aluminum-plastic tape 4 on the unwinding rack 2 start to unwind. The wire stabilizer 10 guides the cable 3 to ensure the fixed position of the cable 3 and provides a stable reference for the wrapping of the aluminum-plastic tape 4. The tape stabilizer 9 guides the aluminum-plastic tape 4 to ensure that the aluminum-plastic tape 4 stably passes under the cable 3 and prevents deviation.

[0035] When the aluminum-plastic tape 4 passes through the arc-shaped guide frame 12, it gradually deforms under its action, initially conforming to the outer contour of the cable 3, reducing the working pressure of the subsequent longitudinal wrapping assembly 51, and making the deformation process of the aluminum-plastic tape 4 more uniform. When the cable 3 and the aluminum-plastic tape 4 move to the fixed pulley 726, the air cylinder 521 is activated. The output end of the air cylinder 521 pushes the connecting plate 522, driving the left and right sliding plates 511 to move upward, thereby driving the two telescopic rods 512 to move upward, and further driving the telescopic section of the spring telescopic rod 524 to move synchronously upward. During the upward movement of the telescopic section of the spring telescopic rod 524, it will first cross the transition arc surface between the lower check section 5251 and the covering section 5252 and enter the covering section 5252, and then move along the arc track of the covering section 5252, thereby driving the telescopic section of the telescopic rod 512 to also move synchronously, and further driving the pulley to move upward along the outer contour of the cable 3. First, it pushes the initially deformed aluminum-plastic tape 4 to closely adhere to the cable 3, and then pushes the aluminum-plastic tape 4 to further deform around the cable 3 until it is completely wrapped around the outside of the cable 3.

[0036] When the telescopic section of the spring telescopic rod 524 moves into the upper check groove, a wrapping action is completed. Then, the output end of the air cylinder 521 contracts, driving the sliding plate 511 to move downward, thereby driving the telescopic rod 512 to move downward, and further driving the spring telescopic rod 524 to move synchronously downward. During this process, the telescopic end of the spring telescopic rod 524 first crosses the transition arc surface between the upper check section 5253 and the reset section 5254, and then resets along the reset section 5254 and finally moves into the lower check section 5251 to complete the reset. Finally, the output end of the air cylinder 521 continuously repeats the above wrapping and reset operations to achieve the longitudinal wrapping operation of the cable 3.

[0037] Refer to Figure 1 and Figure 2 On the front side of the longitudinal wrapping assembly 51, there is a hot pressing mechanism 6 for hot air heating and extrusion bonding of the longitudinally wrapped aluminum-plastic tape 4. The hot pressing mechanism 6 includes a hot air hood 61 fixedly installed on the top of the workbench 8, and a hot air pipe 62 fixedly installed on the top of the hot air hood 61. The hot air pipe 62 is connected to an external hot air blower.

[0038] During specific use, when the aluminum-plastic tape 4 is wrapped around the cable 3 under the action of the longitudinal wrapping assembly 51, the hot air pipe 62 introduces the hot air generated by the external hot air blower into the hot air hood 61, and the hot air evenly blows towards the longitudinal joint of the aluminum-plastic tape 4 in the hot air hood 61, making the aluminum-plastic tape 4 heat-softened. Since the opening diameter of the outlet end of the hot air hood 61 is the same as the diameter of the cable 3 after being wrapped with the aluminum-plastic tape 4, when the softened aluminum-plastic tape 4 passes through the hot air hood 61 following the cable 3, the outlet edge will exert a uniform extrusion effect on it, making the edges of the aluminum-plastic tape 4 closely adhere to achieve bonding, thereby forming a seamless and sealed coating layer outside the cable 3. As the cable 3 continues to move, the hot pressing process continues, ensuring that the entire coating layer of the aluminum-plastic tape 4 can be fully heated and extrusion-bonded.

[0039] Refer to Figure 2 、 Figure 4 and Figure 6 As shown in, a cleaning mechanism 7 is provided on the front side of the hot pressing mechanism 6. The cleaning mechanism 7 includes a brushing assembly 71 for brushing and removing impurities on the outer surface of the cable 3 before entering the head 11 of the extruder, and two traction drive assemblies 72 which are used to cooperate with the corresponding longitudinal wrapping assembly 51 to reciprocate, drive the brushing assembly 71, and are distributed left and right.

[0040] Refer to Figure 2 、 Figure 4 and Figure 6 As shown in, the cleaning mechanism 7 further includes an air duct 73 for connecting the hot pressing mechanism 6 and the brushing assembly 71. The air duct 73 guides the hot air for heating the aluminum-plastic tape 4 in the hot pressing mechanism 6 to the brushing assembly 71 for auxiliary cleaning and impurity removal.

[0041] Refer to Figure 2 、 Figure 4 and Figure 6 As shown in, the brushing assembly 71 includes a dust collection box 711 fixedly penetrating through the workbench 8. Rotating shafts 712 are rotatably penetrated through the left and right inner walls of the dust collection box 711. Soft brushes 713 are fixedly installed at the adjacent ends of the two rotating shafts 712.

[0042] Refer to Figure 2 、 Figure 4 and Figure 6 As shown in, the traction drive assembly 72 includes a fixed seat 721 fixedly installed on the top of the workbench 8. A plurality of installation grooves 722 are opened at the rear side of the fixed seat 721. A rack 724 is fixedly installed at the rear side of the installation groove 722 through a return spring 723. A gear 725 meshing with the corresponding rack 724 is fixedly sleeved at the end of the rotating shaft 712 away from the soft brush 713. The rack 724 is in an L shape, and teeth are formed on the top of the horizontal section of the rack 724.

[0043] Refer to Figure 2 、 Figure 4 and Figure 6 As shown in, a fixed pulley 726 is fixedly installed on the top of the workbench 8. A traction rope 727 is wound around the outside of the fixed pulley 726. A traction frame 728 is fixedly installed at the top of the telescopic rod 512. The two ends of the traction rope 727 are respectively connected to the traction frame 728 and the rack 724.

[0044] Refer to Figure 2 As shown in, through holes for passing through the cable 3 are opened in the middle parts of the hot air hood 61 and the dust collection box 711 and penetrate through the front and rear.

[0045] During specific use, when the telescopic rod 512 moves upward along with the sliding plate 511, it will pull the traction rope 727 to move upward through the traction frame 728. At the same time, under the action of the fixed pulley 726, the upward pulling force direction is converted into a horizontal direction, so that the traction rope 727 pulls the rack 724 to drive the gear 725 to rotate, and at the same time stretches the return spring 723, thereby driving the rotating shaft 712 to rotate, and then driving the soft brush 713 to rotate accordingly, to brush the outer surface of the cable 3 passing through the dust collection box 711 and remove impurities such as dust on the surface of the cable 3.

[0046] When the telescopic rod 512 moves downward along with the sliding plate 511, the traction rope 727 gradually relaxes, and at the same time the return spring 723 gradually returns to its original position, thereby driving the rack 724 to reset and driving the gear 725 to rotate again, so as to drive the soft brush 713 to rotate in the reverse direction and brush the outer surface of the cable 3 passing through the dust collection box 711 again from different angles.

[0047] Meanwhile, when the hot pressing mechanism 6 is working, hot air is generated inside the hot air hood 61, and the air guiding pipe 73 guides the hot air into the dust collection box 711 and blows it downward from top to bottom. On the one hand, the hot air can make the impurities on the surface of the cable 3 easier to detach, enhancing the cleaning effect; on the other hand, it can blow the brushed impurities downward and discharge them through the bottom of the dust collection box 711, playing an auxiliary role in removing impurities.

[0048] Finally, the cable 3 that has been cleaned and longitudinally wrapped passes through the extrusion head 11 of the extruder. The die inside the extrusion head 11 of the extruder will guide the plastic melt to uniformly coat the surface of the cable 3 that has been constrained and shaped, forming a plastic sheath to enhance the mechanical properties and electrical insulation performance of the cable 3. After the cable 3 is extruded from the extrusion head 11 of the extruder, it directly enters the external cooling water tank to cool and solidify the plastic sheath.

[0049] It should be noted that the above extrusion head 11 of the extruder and its working process are both prior arts, so they will not be elaborated in this application.

[0050] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
