Description

Technical Field

[0001] The invention belongs to the technical field of packaging equipment, and in particular relates to a cable packaging machine. Background Art

[0002] Cable is a wire product used to transmit electric energy in power information engineering. Cable consists of a core and an insulating layer covering the core. In order to facilitate transportation and storage, the cable will be coiled into a cable roll after processing, and then wrapped with plastic film to play a role in waterproofing and dustproofing.

[0003] In the prior art, there are two main cable packaging methods: wrapping packaging and film packaging. Wrapping packaging is to wrap a plastic packaging tape around the cable roll. The advantage of this packaging method is that it is simple and easy to operate, but the disadvantage is that it is easy to produce wrinkles due to the stacking of the packaging tape, and the appearance is poor. Film packaging is to transport the wire roll between the upper and lower layered plastic films (PE heat shrink film), and then heat-seal and cut the upper and lower layers of plastic film so that the upper and lower layers of plastic film form a plastic bag that wraps the cable roll. This operation is called "bagging". After the bagging is completed, the cable roll with the plastic film on the outside is transported to the heat shrink device. Since the PE heat shrink film is provided with air holes, the PE heat shrink film shrinks under high temperature environment, and the air is discharged from the air holes. After the heat shrinkage is completed, the PE heat shrink film can form a plastic protective layer on the outer surface of the wire roll. The advantage of film packaging is that it is beautiful, but the disadvantage is that the hollow part in the middle of the cable roll will be wrapped in the film. In this way, during the handling or transportation of the cable roll, the plastic film in the hollow position is prone to tearing, perforation and other damage problems, affecting the packaging quality of the wire roll. Summary of the invention

[0004] The invention provides a cable packaging machine, aiming to solve the problem in the prior art that a hollow part of a cable roll is wrapped into a film during film packaging.

[0026] A feeding conveyor, arranged on the feeding side of the lower film conveying assembly;

[0027] A material unloading conveyor, arranged on the unloading side of the lower film conveying assembly;

[0028] A heat shrink film sealing machine is arranged on the unloading side of the unloading conveyor; and

[0034] The cable packaging machine provided by the present invention includes a first bracket, a lower film conveying assembly, a second bracket, an upper film conveying assembly, a third bracket and a film sealing assembly.

[0058] Please also read Figures 1 to 10 , the cable packaging machine 1 provided by the present invention is described below.

[0059] See also Figures 1 to 5 The present invention provides a cable packaging machine 1, comprising a first bracket 10, a lower film conveying assembly 20, a second bracket 30, an upper film conveying assembly 40, a third bracket 50, and a film cutting assembly. Among them, the first bracket 10 has a carrying plate 11; the lower film conveying assembly 20 includes a first unwinding mechanism 21 and a first winding mechanism 22, the first unwinding mechanism 21 and the first winding mechanism 22 are arranged on the first bracket 10 at intervals along the conveying direction of the lower packaging film 24, and the carrying plate 11 is located below the lower packaging film 24; the second bracket 30 is arranged above the carrying plate 11, and an adjustment groove is opened along the conveying direction of the upper packaging film 44; the upper film conveying assembly 40 includes a second unwinding mechanism 41, a second winding mechanism 42, and a surplus compensation mechanism 43, the second unwinding mechanism 41 and the second winding mechanism 42 are arranged on the second bracket 30 at intervals along the conveying direction of the upper packaging film 44, the surplus compensation mechanism 43 includes two adjustment shafts 431, and an adjustment drive unit, the second unwinding mechanism 41 and the second winding mechanism 42 are located at the same height, and are arranged at intervals along the conveying direction of the upper packaging film 44, the adjustment shaft 431 is located below the second unwinding mechanism 41 and the second winding mechanism 42, and the upper packaging film 44 is arranged at an angle of 0. Figure 5The path is set as shown. Two adjustment shafts 431 are arranged between the second unwinding mechanism 41 and the second winding mechanism 42, and are respectively slidably matched with the adjustment grooves. The upper packaging film 44 is wound around the adjustment shafts 431, and the adjustment drive unit is used to drive the two adjustment shafts 431 to move closer to or away from each other; the third bracket 50 is arranged above the second bracket 30; the film sealing assembly 60 includes an inner ring heat sealing knife 61, an outer ring heat sealing knife 62, and a lifting mechanism 63. The inner ring heat sealing knife 61 and the outer ring heat sealing knife 62 are coaxially arranged on the third bracket 50 and are both located above the upper packaging film 44. The lifting mechanism 63 is used to drive the inner ring heat sealing knife 61 and the outer ring heat sealing knife 62 to move vertically; the lifting mechanism 63 is linked with the adjustment drive unit. When the inner ring heat sealing knife 61 and the outer ring heat sealing knife 62 move downward, the adjustment drive unit can drive the two adjustment shafts 431 to move closer to each other. When the inner ring heat sealing knife 61 and the outer ring heat sealing knife 62 are reset upward, the adjustment drive unit can drive the two adjustment shafts 431 to move away from each other for reset.

[0060] The moving speed, moving stroke and other parameters of the motor actuators such as the first bracket 10, the lower film conveying assembly 20, the second bracket 30, the upper film conveying assembly 40, the third bracket 50, and the film cutting assembly can be set according to actual conditions and can be specifically controlled by a PLC controller.

[0061] Compared with the prior art, the cable packaging machine 1 provided in the embodiment of the present invention has the following beneficial effects:

[0062] The cable packaging machine 1 provided by the embodiment of the present invention includes a first bracket 10, a lower film conveying assembly 20, a second bracket 30, an upper film conveying assembly 40, a third bracket 50 and a film sealing assembly 60. The upper film conveying assembly 40 and the lower film conveying assembly 20 are arranged relative to each other up and down, and the upper packaging film 44 and the lower packaging film 24 are respectively parallel to the supporting plate 11, and a packaging space for accommodating the cable roll is formed between the two. When in use, the cable roll to be packaged is first placed between the upper packaging film 44 and the lower packaging film 24, and the cable roll is supported by the supporting plate 11, and then the film sealing assembly 60 works, and the lifting mechanism 63 can drive the inner ring heat sealing knife 61 and the outer ring heat sealing knife 62 to move downward, perform heat sealing and cutting of the upper packaging film 44 and the lower packaging film 24, and wrap the cable roll in the film to complete the packaging of the cable roll.

[0063] See also Fig. 9 and Fig.10Since the inner ring heat sealing knife 61 and the outer ring heat sealing knife 62 will stretch the upper packaging film 44 when they move downward, in order to prevent the upper packaging film 44 from being broken or excessively deformed, the upper film conveying assembly 40 in the embodiment of the present invention is also provided with a surplus compensation mechanism 43, and the surplus compensation mechanism 43 can adjust the distance between the two adjustment shafts 431 by adjusting the driving unit. In this way, when the inner ring heat sealing knife 61 and the outer ring heat sealing knife 62 move downward, the two adjustment shafts 431 are close to each other, so that the upper packaging film 44 forms a film cutting surplus for the inner ring heat sealing knife 61 and the outer ring heat sealing knife 62 to stretch downward, thereby ensuring that the upper packaging film 44 and the lower packaging film 24 can be successfully heat-sealed and cut.

[0064] The embodiment of the present invention can obtain a ring-shaped packaging bag by providing a film sealing assembly 60 having an inner ring heat sealing knife 61 and an outer ring heat sealing knife 62, thereby solving the problem that the hollow part of the cable roll will be wrapped into the film when the cable roll is covered with film. By providing a surplus compensation mechanism 43, it is possible to provide film cutting surplus compensation when the film sealing assembly 60 drives the upper packaging film 44 to move downward, thereby ensuring that the upper packaging film 44 is not broken or excessively deformed. By providing a lower film conveying assembly 20 and an upper film conveying assembly 40, the unwinding and rewinding of the upper and lower films can be automatically completed after the film cutting is completed, which helps to achieve continuous packaging. The first bracket 10, the lower film conveying assembly 20, the second bracket 30, the upper film conveying assembly 40, the third bracket 50 and the film sealing assembly 60 work together to complete the packaging of the cable roll, and obtain a cable roll packaging product with beautiful appearance and the hollow part of the cable roll not easily damaged.

[0065] In the embodiment of the present invention, the first bracket 10, the second bracket 30 and the third bracket 50 are used to provide support and fixation for the components installed thereon, and there is no limitation on their specific shapes and structures, and they can be made by welding steel sections, pipes or steel plates.

[0066] The lower film conveying assembly 20 includes a first unwinding mechanism 21 and a first winding mechanism 22, and the upper film conveying assembly 40 includes a second unwinding mechanism 41 and a second winding mechanism 42, wherein the first unwinding mechanism 21 and the second unwinding mechanism 41 are used to release new packaging films, and the first winding mechanism 22 and the second winding mechanism 42 are used to wind up the film waste remaining after the film is cut. The first unwinding mechanism 21, the first winding mechanism 22, the second unwinding mechanism 41 and the second winding mechanism 42 are arranged as shown in the following figure: Figure 3 and Figure 5 As shown, but not limited to this. Since the above components work in a similar manner, the first unwinding mechanism 21, the first rewinding mechanism 22, the second unwinding mechanism 41 and the second rewinding mechanism 42 can adopt the same structure to complete the unwinding and retracting operation of the packaging film.

[0067] It should be noted that in order to successfully complete the packaging operation, the cable roll needs to be placed coaxially with the inner ring heat sealing knife 61, the width of the lower packaging film 24 should be greater than the maximum diameter of the cable roll, and the width of the upper packaging film 44 can be greater than the width of the lower packaging film 24. The upper packaging film 44 and the lower packaging film 24 can use PE heat shrinkable films in the prior art, which have air holes to facilitate the discharge of internal air during heat shrinkage. The cable roll can be manually picked up and placed, or it can be automatically picked up and placed by the robot 742.

[0068] The film sealing assembly 60 includes an inner ring heat sealing knife 61, an outer ring heat sealing knife 62 and a lifting mechanism 63. The inner ring heat sealing knife 61 and the outer ring heat sealing knife 62 have the same structure and working principle, but the difference is that the diameters of the inner ring heat sealing knife 61 should be smaller than the inner diameter of the cable roll, and the diameter of the outer ring heat sealing knife 62 should be larger than the outer diameter of the cable roll.

[0069] The function of the inner ring heat sealing knife 61 and the outer ring heat sealing knife 62 is to heat-melt the upper packaging film 44 and the lower packaging film 24 together by using their own heating parts after the upper packaging film 44 and the lower packaging film 24 overlap, thereby forming an annular packaging bag wrapped around the cable roll. The inner ring heat sealing knife 61 and the outer ring heat sealing knife 62 can be circular, or they can be square, regular pentagon, regular hexagon, regular octagon and the like. Preferably, they are circular. The inner ring heat sealing knife 61 and the outer ring heat sealing knife 62 adopt an electrically heated structure, and their structure and working principle are no different from the heat sealing cutter used for packaging film in the prior art, which will not be repeated here.

[0070] When performing film cutting and heat sealing of the plastic film, the lifting mechanism 63 can drive the inner ring heat sealing knife 61 and the outer ring heat sealing knife 62 to move downward. After the film cutting is completed, the lifting mechanism 63 drives them to reset. The inner ring heat sealing knife 61 and the outer ring heat sealing knife 62 can be lifted and lowered together. Alternatively, as a better implementation method, the lifting mechanism 63 includes a first lifting unit connected to the inner ring heat sealing knife 61 and a second lifting unit connected to the outer ring heat sealing knife 62. When film cutting and heat sealing are required, the inner ring heat sealing knife 61 is first driven downward by the first lifting unit. After the heat sealing of the inner ring is completed, the second lifting unit drives the outer ring heat sealing knife 62 to move downward to perform heat sealing and cutting of the outer ring.

[0071] like Fig. 9 and Fig.10As shown, when the inner ring heat sealing knife 61 and the outer ring heat sealing knife 62 move downward, the upper packaging film 44 will be pressed down accordingly. At this time, the margin compensation mechanism 43 works, and the two adjustment shafts 431 are driven to approach each other by the adjustment drive unit, thereby leaving a film cutting margin for the upper packaging film 44 to be pressed down, so as to prevent the upper packaging film 44 from being broken or over-stretched and deformed. After the film cutting is completed, during the upward reset period of the inner ring heat sealing knife 61 and the outer ring heat sealing knife 62, the two adjustment shafts 431 are driven to move away from each other and reset by the adjustment drive unit. In the process of the two adjustment shafts 431 approaching or moving away from each other, the upper packaging film 44 is always kept in a tensioned state to prevent wrinkles.

[0072] The adjustment drive unit may be a drive member capable of realizing linear reciprocating movement, such as an electric telescopic rod and a telescopic cylinder.

[0073] See also Figure 4 , Figure 5 and Figure 6 In some possible embodiments, the first unwinding mechanism 21 includes an unwinding shaft 211 and an unwinding motor 212. The unwinding shaft 211 is horizontally arranged on the first bracket 10 and is rotatably matched with the first bracket 10. The axial direction of the unwinding shaft 211 is perpendicular to the conveying direction of the lower packaging film 24, and the lower packaging film 24 is wound around the unwinding shaft 211. The unwinding motor 212 is arranged on the first bracket 10, and is used to drive the unwinding shaft 211 to rotate around its own axis, thereby completing the release of the lower packaging film 24. The structures of the first rewinding mechanism 22, the second unwinding mechanism 41 and the second rewinding mechanism 42 are similar to those of the first unwinding mechanism 21, and are not described in detail here.

[0074] See also Figure 4 , Figure 5 and Figure 6 In some possible embodiments, the lower film conveying assembly 20 further includes at least one tensioning shaft 23 , which is disposed between the first unwinding mechanism 21 and the first winding mechanism 22 , and rotatably cooperates with the first bracket 10 , and the upper packaging film 44 is wound around the tensioning shaft 23 .

[0075] The tensioning shaft 23 is used to keep a certain tension on the lower packaging film 24 to prevent it from wrinkling and affecting the packaging effect. The tensioning shaft 23 can be as follows Figure 6 As shown, two are provided, and the first unwinding mechanism 21 and the first winding mechanism 22 are arranged below the tensioning shaft 23, with a compact structure and a reasonable layout.

[0076] See also Figure 1 The carrier plate 11 is provided with a waste outlet 111 that penetrates the thickness of the carrier plate 11. The radial dimension of the waste outlet 111 corresponds to the radial dimension of the inner ring heat sealing knife 61. Under the premise of not affecting the heat sealing and cutting of the inner ring heat sealing knife 61, the size of the waste outlet 111 is the same as or slightly smaller than the size of the inner ring heat sealing knife 61. The waste outlet 111 is used for the circular waste cut off by the inner ring heat sealing knife 61 to fall.

[0077] In some possible embodiments, a collection pipe is connected below the waste outlet 111, and the collection pipe is connected to a negative pressure fan. The negative pressure fan and the collection pipe function like a vacuum cleaner, and can generate negative pressure suction to absorb the cut circular waste and complete the automatic collection of the waste.

[0078] See also Figure 1 , Figure 3 and Figure 4 In some possible embodiments, the adjustment drive unit includes a bidirectional screw 432 and a screw motor 433. The bidirectional screw 432 is rotatably arranged on the second bracket 30, and the bidirectional screw 432 has a first thread segment and a second thread segment spaced apart in the axial direction, and the first thread segment and the second thread segment have opposite spiral directions, and the two adjustment shafts 431 are respectively threadedly matched with the first thread segment and the second thread segment; the screw motor 433 is arranged on the second bracket 30, and is used to drive the bidirectional screw 432 to rotate around its own axis. By controlling the rotation direction of the bidirectional screw 432, the two adjustment shafts 431 can be moved closer to or farther away from each other.

[0079] See also Figure 5 , Figure 7 and Figure 8 In some possible embodiments, the film sealing assembly 60 further includes a pre-pressing mechanism 64, which includes a plurality of first elastic telescopic rods 641 and a plurality of second elastic telescopic rods 642. The plurality of first elastic telescopic rods 641 are arranged at intervals along the circumferential direction on the outer periphery of the inner ring heat sealing knife 61, and a first pressing wheel 6414 is provided at the bottom of the first elastic telescopic rods 641; the plurality of second elastic telescopic rods 642 are arranged at intervals along the circumferential direction on the outer periphery of the outer ring heat sealing knife 62, and a second pressing wheel is provided at the bottom of the second elastic telescopic rods 642.

[0080] The pre-pressing mechanism 64 is used to press down the inner ring heat sealing knife 61 and the outer ring heat sealing knife 62 before they contact the packaging film. Such a configuration can achieve a better pressing effect on the one hand, and on the other hand, it can also prevent the inner ring heat sealing knife 61 and the outer ring heat sealing knife 62 from contacting the upper packaging film 44 too early and cutting it. The first elastic telescopic rod 641 can be raised and lowered together with the inner ring heat sealing knife 61, and the second elastic telescopic rod 642 can be raised and lowered together with the outer ring heat sealing knife 62. The first elastic telescopic rod 641 and the second elastic telescopic rod 642 have the same structure. The first elastic telescopic rod 641 includes a sleeve 6411, a spring 6412, a rod body 6413 and a first pressing wheel 6414. The rod body 6413 is slidably arranged in the sleeve 6411, and the first pressing wheel 6414 is rotatably arranged at the lower end of the rod body 6413. The first pressing wheel 6414 can be made of plastic, ceramic, metal, rubber and other materials. Under the action of the spring 6412, the rod body 6413 extends downward from the sleeve 6411.

[0081] In the free state, the height of the rod body 6413 and the first pressing wheel 6414 is lower than the bottom of the inner ring heat sealing knife 61 and the outer ring heat sealing knife 62, so that when it moves downward, the first pressing wheel 6414 first contacts the upper packaging film 44 until the upper packaging film 44 and the lower packaging film 24 are overlapped.
