Description

Technical Field

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

[0002] In the field of power cable processing technology, the process of using longitudinally wrapped aluminum-plastic tape to bond a polyethylene inner sheath or a flame-retardant polyolefin inner sheath as a waterproof isolation sleeve has been widely used. In the existing technology, the cable sheath processing equipment usually includes a longitudinally wrapped horn mold, a line stabilizing mold, a sizing mold and a thermal control device. Its core technical route is "three-stage mold progressive deformation + thermal control bonding and shaping": the aluminum-plastic tape is first deformed from a flat plate to a tubular shape by the longitudinally wrapped horn mold, and then gradually reduced to the designed size by the line stabilizing mold and the sizing mold. Finally, the edge film of the aluminum-plastic tape is heated by a hot air blower to achieve bonding and shaping. However, the process of controlling the deformation of the aluminum-plastic tape and covering the cable by the horn mold still has certain defects:

[0003] When the aluminum-plastic strip is guided by the horn mold, it enters from the larger end of the horn mold and is squeezed and deformed in the gradually shrinking mold cavity, ultimately wrapping around the cable. This method relies on the shape of the horn mold to force the aluminum-plastic strip to deform. During the horn mold wrapping process, the extrusion pressure on the aluminum-plastic strip varies greatly at different locations within the mold cavity, with greater pressure near the inner wall and relatively less pressure in the center. This can easily lead to uneven deformation of the aluminum-plastic strip, prone to wrinkling or excessive stretching. Furthermore, after deformation by the horn mold, the aluminum-plastic strip has a poor fit with the outer contour of the cable, requiring subsequent step-by-step adjustment using the line stabilization die and sizing die.

[0006] A cleaning mechanism is provided on the front side of the hot pressing mechanism, and an extruder head is fixedly installed on the top of the frame in front of the cleaning mechanism. The cleaning mechanism includes a sweeping brush assembly for sweeping and removing impurities from the outer surface of the cable before entering the extruder head, and two groups of traction drive assemblies distributed on the left and right to cooperate with the corresponding longitudinal wrapping assembly to move back and forth and pull the sweeping brush assembly.

[0007] The cleaning mechanism also includes an air duct for connecting the hot pressing mechanism and the sweeping brush assembly. The air duct guides the hot air heated by the hot pressing mechanism to the sweeping brush assembly for auxiliary cleaning and impurity removal.

[0008] Furthermore, the two groups of longitudinal wrapping components are symmetrical on the left and right and are staggered in the front-to-back direction. The longitudinal wrapping components include a sliding plate that slides up and down through the workbench and a telescopic rod fixedly installed on the top of the sliding plate. The telescopic rod has a roller installed on one end near the center of the workbench for rotation.

[0009] Furthermore, the control component includes a cylinder fixedly installed on the bottom of the workbench and a connecting plate fixedly installed on the output end of the cylinder and connecting the left and right sliding plates. A sliding groove is opened on the rear side of the fixed section of the telescopic rod, and a spring telescopic rod slidingly connected in the sliding groove is fixedly installed on the rear side of the telescopic section of the telescopic rod.

[0010] Furthermore, a fixing plate is fixedly installed on the top of the workbench, a control groove is opened on the front side of the fixing plate, and the telescopic section of the spring telescopic rod is slidably connected in the control groove.

[0011] Furthermore, the hot pressing mechanism includes a hot air hood fixedly mounted on the top of the workbench, and a hot air pipe is fixedly mounted on the top of the hot air hood.

[0012] Furthermore, the sweeping brush assembly includes a dust box fixedly passing through the workbench, and a rotating shaft is rotatably passed through the left and right inner walls of the dust box, and a soft brush is fixedly installed at one end of the two rotating shafts.

[0013] Furthermore, the traction drive assembly includes a fixed base fixedly installed on the top of the workbench, a plurality of mounting grooves are opened on the rear side of the fixed base, a rack is fixedly installed on the rear side of the mounting groove through a reset spring, and a fixed sleeve is provided at the end of the rotating shaft away from the soft brush with a gear meshing with the corresponding rack, the rack is L-shaped, and the teeth are opened at the top of the horizontal section of the rack.

[0014] Furthermore, a fixed pulley is fixedly installed on the top of the workbench, a traction rope is wound around the outer side of the fixed pulley, a traction frame is fixedly installed on the top of the telescopic rod, and both ends of the traction rope are respectively connected to the traction frame and the rack.

When the telescopic section of the spring telescopic rod moves in the wrapping section of the control groove, it drives the telescopic rod and the roller to move strictly according to the outer contour of the cable. This enables the aluminum-plastic tape to fit closely to the surface of the cable when the roller pushes it, and evenly wrap the cable from all angles, avoiding problems such as loose fit and excessive gaps.

DETAILED DESCRIPTION

[0028] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that these embodiments are discussed to enable those skilled in the art to better understand and implement the subject matter described herein. The functions and arrangements of the elements discussed may be varied without departing from the scope of protection of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0029] See Figure 1 and Figure 2 In this embodiment, an aluminum foil longitudinal wrapping device suitable for cables is proposed, including a frame 1 and a reeling frame 2 arranged on the top of the frame 1, a cable 3 and an aluminum-plastic tape 4 are wound on the reeling frame 2, a reciprocating longitudinal wrapping mechanism 5 is provided on the top of the frame 1 through a workbench 8, a belt stabilizer 9 and an extruder head 11 located in front of the workbench 8 are fixedly installed on the top of the frame 1, the belt stabilizer 9 is located on the rear side of the workbench 8 and is used to guide the aluminum-plastic tape 4, a wire stabilizer 10 and several arc-shaped guide frames 12 are fixedly installed on the top of the workbench 8, the arc-shaped guide frames 12 are located on the rear side of the reciprocating longitudinal wrapping mechanism 5 and are used to guide the aluminum-plastic tape 4 to gradually deform, and the wire stabilizer 10 is located on the rear side of the arc-shaped guide frame 12 and is used to guide the cable 3.

[0030] See Figure 2 、 Figure 3 and Figure 5The reciprocating longitudinal wrapping mechanism 5 includes two groups 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 are distributed left and right, and a control component 52 for controlling the reciprocating movement of the longitudinal wrapping components 51. The two groups of longitudinal wrapping components 51 are symmetrical left and right and are staggered in the front and back directions. The longitudinal wrapping component 51 includes a sliding plate 511 that slides up and down through the workbench 8 and a telescopic rod 512 fixedly installed on the top of the sliding plate 511. The telescopic rod 512 is rotatably installed with a roller 513 at one end near the center of the workbench 8.

[0031] See 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 connecting the left and right sliding plates 511. A sliding groove 523 is provided on the rear side of the fixed section of the telescopic rod 512, and a spring telescopic rod 524 slidingly connected in the sliding groove 523 is fixedly installed on the rear side of the telescopic section of the telescopic rod 512.

[0032] See Figure 2 、 Figure 3 、 Figure 5 and Figure 7 A fixing plate 526 is fixedly installed on the top of the workbench 8, and a control groove 525 is opened on 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] See Figure 7 The control groove 525 includes a lower check segment 5251 located at the lower right corner of the fixed plate 526. The upper part of the lower check segment 5251 is connected with a covering segment 5252 and an upper check segment 5253 in sequence. The covering segment 5252 is arc-shaped, and the inner arc diameter of the covering segment 5252 matches the diameter of the cable 3. A reset segment 5254 is connected between the upper check segment 5253 and the lower check segment 5251. The connection between the lower check segment 5251 and the covering segment 5252 and the connection between the upper check segment 5253 and the reset segment 5254 are both provided with transition arc surfaces.

[0034] During specific use, the cable 3 and the aluminum-plastic tape 4 on the unwinding rack 2 begin to unwind, the wire stabilizer 10 guides the cable 3 to ensure that the position of the cable 3 is fixed, 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 passes stably from under the cable 3 to prevent deviation.

[0035] When the aluminum-plastic belt 4 passes through the arc-shaped guide frame 12, it gradually deforms under its action, initially fitting the outer contour of the cable 3, reducing the working pressure of the subsequent longitudinal wrapping component 51, making the deformation process of the aluminum-plastic belt 4 more uniform. When the cable 3 and the aluminum-plastic belt 4 move to the fixed pulley 726, the cylinder 521 is started, and the output end of the 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 then driving the telescopic section of the spring telescopic rod 524 to move upward synchronously. 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 trajectory of the covering section 5252, thereby driving the telescopic section of the telescopic rod 512 to move synchronously, and then driving the pulley to move upward again and move along the outer contour of the cable 3, first pushing the initially deformed aluminum-plastic belt 4 to fit closely to the cable 3, and then pushing the aluminum-plastic belt 4 to further deform around the cable 3 until it is completely covered on the outside of the cable 3.

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

[0037] See Figure 1 and Figure 2 The front side of the longitudinal wrapping component 51 is provided with a hot pressing mechanism 6 for hot air heating and extrusion bonding of the longitudinally wrapped aluminum-plastic strip 4. The hot pressing mechanism 6 includes a hot air hood 61 fixedly mounted on the top of the workbench 8. A hot air pipe 62 is fixedly mounted on the top of the hot air hood 61, and the hot air pipe 62 is connected to an external hot air blower.

[0038] In specific use, after 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 guides the hot air generated by the external hot air blower into the hot air hood 61. The hot air is evenly blown toward the longitudinal wrapping seam of the aluminum-plastic tape 4 within the hot air hood 61, causing the aluminum-plastic tape 4 to be heated and softened. Because the opening diameter of the outlet end of the hot air hood 61 is consistent with the diameter of the cable 3 after being wrapped with the aluminum-plastic tape 4, the outlet edge will exert a uniform pressure on the softened aluminum-plastic tape 4 as it passes through the hot air hood 61 with the cable 3, causing the edge of the aluminum-plastic tape 4 to fit tightly and achieve adhesion, thereby forming a seamless, sealed coating on the outside of the cable 3. As the cable 3 continues to move, the hot pressing process continues, ensuring that the entire aluminum-plastic tape 4 coating is fully heated and extruded and bonded.

[0039] See Figure 2 、 Figure 4 and Figure 6 A cleaning mechanism 7 is provided on the front side of the hot pressing mechanism 6. The cleaning mechanism 7 includes a sweeping brush assembly 71 for sweeping and removing impurities from the outer surface of the cable 3 before entering the extruder head 11, and two groups of traction drive assemblies 72 for cooperating with the corresponding longitudinal wrapping assembly 51 to move back and forth and pulling the sweeping brush assembly 71 and distributed on the left and right.

[0040] See Figure 2 、 Figure 4 and Figure 6 The cleaning mechanism 7 also includes an air duct 73 for connecting the hot pressing mechanism 6 and the sweeping brush assembly 71. The air duct 73 guides the hot air heated by the hot pressing mechanism 6 to the sweeping brush assembly 71 for auxiliary cleaning and impurity removal.

[0041] See Figure 2 、 Figure 4 and Figure 6 The sweeping brush assembly 71 includes a dust box 711 fixedly passing through the workbench 8. The left and right inner walls of the dust box 711 are both rotatably penetrated by a rotating shaft 712. Soft brushes 713 are fixedly installed near one end of the two rotating shafts 712.

[0042] See Figure 2 、 Figure 4 and Figure 6 The traction drive assembly 72 includes a fixed base 721 fixedly mounted on the top of the workbench 8, and a plurality of mounting grooves 722 are opened on the rear side of the fixed base 721. A rack 724 is fixedly installed on the rear side of the mounting groove 722 through a return spring 723. The rotating shaft 712 is fixedly sleeved with a gear 725 meshing with the corresponding rack 724 at one end away from the soft brush 713. The rack 724 is L-shaped, and the teeth are opened at the top of the horizontal section of the rack 724.

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

[0044] See Figure 2 The middle of the hot air cover 61 and the dust collecting box 711 are both provided with a through hole that runs through from front to back and is used to pass the cable 3.

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

[0046] When the telescopic rod 512 moves downward with the sliding plate 511, the traction rope 727 gradually relaxes, and the reset spring 723 gradually resets, thereby driving the rack 724 to reset and driving the gear 725 to rotate again, thereby driving the soft brush 713 to rotate in the opposite direction, and sweeping the outer surface of the cable 3 passing through the dust box 711 again from different angles.

[0047] At the same time, when the hot pressing mechanism 6 is working, hot air is generated in the hot air hood 61, and the air duct 73 guides the hot air into the dust box 711 and blows it from top to bottom. On the one hand, the hot air can make it easier to remove impurities on the surface of the cable 3, thereby enhancing the cleaning effect; on the other hand, the impurities swept down can be blown downward and discharged through the bottom of the dust box 711, thereby assisting in the removal of impurities.

[0048] Finally, the cleaned and longitudinally wrapped cable 3 passes through the extruder head 11. The mold inside the extruder head 11 will guide the plastic melt to evenly cover the surface of the constrained and shaped cable 3 to form a layer of plastic sheath, thereby enhancing the mechanical properties and electrical insulation properties of the cable 3. After being extruded from the extruder head 11, the cable 3 directly enters the external cooling water tank to cool and solidify the plastic sheath.

[0049] It should be noted that the above-mentioned extruder head 11 and its working process are both existing technologies, and therefore will not be described in detail in this application.

[0050] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. However, obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
