Description

Technical Field

[0001] The invention belongs to the technical field of cable sheath processing, and in particular relates to special equipment for surface processing of power cable sheath. Background Art

[0002] The cable sheath is the outermost layer of the cable. The sheath is made of relatively rigid material with strong tensile strength and good flame retardant properties. It can provide electrical insulation and protect the inner core of the cable. It also prevents the internal components of the cable from being polluted or affected by external forces. They are resistant to oil, heat, flame, sunlight, aging, acid and alkali. After the overall molding of the cable sheath is completed, the corresponding fonts need to be printed on the outside to facilitate the construction personnel to confirm and use. During this printing process, the outer surface of the cable is prone to high humidity and dust, which affects the quality of the font molding. Therefore, special equipment is required to complete the processing.

[0003] For example, patent application number CN202010704191.5 discloses a special equipment for surface processing of power cable sheath, whose structure includes a processing chamber, a connecting plate, a body, a fixed rotating wheel, a drying device, an adjusting screw, a conveying disc, a traction device, a guide rod, and a positioning seat. When the improved present invention is used, the fan blades rotate to generate wind energy, which is transported to the air suction disc through the through hole, and the air is transported through the two rotating discs to assist the air outlet plate. The wind can be transported to the air outlet pipe through the air outlet plate, and then the air outlet pipe is used to evenly transport the wind to the surface of the cable sheath, and the surface of the cable sheath is evenly dried to improve the protective effect of the sheath; the cable sheath is inserted into the placement cavity, and the cable sheath is output through the rotation of the traction wheel. The fitting pad pushes the friction pad upward, and the traction wheel will contact the friction pad and be subject to a certain resistance, so that the rotation speed of the traction wheel is controlled at a certain speed, and the cable sheath is subjected to uniform tension, which protects the cable sheath just processed and improves the use effect of the sheath.

[0004] In the prior art, the cable sheath can be evenly pulled during printing by using a traction wheel and a friction pad in combination with a suction plate and the like. At the same time, the wind can flow evenly outside, which effectively improves the quality of the hard brush. However, there are still some shortcomings in the overall use process:

[0005] Firstly, in the prior art, only the cable sheath is dried after hard brushing. However, the cable sheath undergoes a long period of transportation and storage before printing, and a large amount of moisture and dust easily remain on the surface. During the printing process, these moisture and dust are easily brought into the printing equipment, causing uneven adhesion, tilting and crookedness of the printed fonts, which seriously affects the printing quality.

[0006] Secondly, the prior art only stabilizes the sheath in the transport state, but the sheath tube is prone to shaking and slipping on the line roller during the winding and delivery process, causing the sheath tube that was originally uniformly wound to become loose and deformed, which affects the tightness of the winding on the one hand, and the stability of the discharge on the other hand, and cannot ensure continuous discharge. Summary of the invention

[0007] In order to overcome the shortcomings of the prior art, the present invention provides a special equipment for processing the surface of a power cable sheath.

At the same time, the sheath tube can be guaranteed not to be loose and slippery, thereby improving the discharge stability.

DETAILED DESCRIPTION

[0036] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Embodiment 1:

[0037] Reference Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 7 and attached Fig.11A special equipment for processing the surface of a power cable sheath comprises a first base 10 and a printing machine 11. The printing machine 11 is arranged on the upper end surface of the first base 10. Second bases 12 are arranged on both sides of the printing machine 11. A bracket 13 is arranged on the upper end surface of the second base 12. A wire-releasing roller 18 and a wire-receiving roller 19 are rotatably arranged in the two brackets 13. Rubber rings 25 are arranged on the outer circumferential surfaces of both sides of the wire-releasing roller 18 and the wire-receiving roller 19. A connecting seat 29 is slidably arranged under each rubber ring 25. A hard block 48 is arranged on the inner end surface of the connecting seat 29. The hard block 48 is arranged on the inner end surface of the connecting seat 29. A sleeve 45 is arranged on the outside of 8, and a hard ball 47 is arranged at the center of the end face of the sleeve 45. Drying components are arranged on the second base 12 below the pay-off roller 18 and the take-up roller 19. Reinforcement tubes 20 are also arranged on both sides of the printing machine 11, and a stabilization component is arranged in the reinforcement tube 20. A connecting tube 21 is arranged on one side wall of the reinforcement tube 20, and a corrugated water retaining ring 31 is arranged in the connecting tube 21. Scraping rings 33 are arranged on the inner circular surface of the bending of the water retaining ring 31 near the center of the circle, and a heating ring 35 is arranged on one side of each scraping ring 33 on the outer circular surface of the bending of the water retaining ring 31.

[0038] Specifically, the first base 10 refers to various objects such as the ground or a processing platform, and is a reference setting for the convenience of indicating the movement of the equipment and the general layout. This scheme will not be elaborated in detail. The printing machine 11 is installed and fixed on the first base 10. It is a prior art, and this scheme will not be elaborated in detail. The printing machine 11 includes a feed end and a discharge end. The staff can put the sheath tube into the inside of the printing machine 11 through the feed end, and then the printing machine 11 will print the sheath tube, and the printed sheath tube will be sent out through the discharge end.

[0039] The pay-off roller 18 and the take-up roller 19 are rotatably arranged in the bracket 13 on the two second bases 12 arranged on both sides of the printing machine 11, and are arranged at the feeding end and the discharging end of the printing machine 11 respectively. The pay-off roller 18 and the take-up roller 19 are provided with two limit disks as a whole. A large number of unprinted sheaths are wound around the outside of the pay-off roller 18. The take-up roller 19 is used to reel up the printed sheath. A driving motor is provided on one end face of the bracket 13. The output end of the driving motor is connected to the end face of the pay-off roller 18 or the take-up roller 19. The pay-off roller 18 and the take-up roller 19 can be driven to rotate by the rotation of the driving motor, thereby completing the sheath retraction and release processing;

[0040] A rubber ring 25 is provided on the limit plate of the pay-off roller 18 and the take-up roller 19. The rubber ring 25 is made of elastic rubber material and has an elastic shock-absorbing effect. A first push cylinder 16 is provided on the end surface of the second base 12 below each rubber ring 25. A connecting seat 29 is connected to the output end of the first push cylinder 16. A hard block 48 provided on the end surface of the connecting seat 29 is made of hard material. The sleeve 45 on the hard block 48 is made of elastic buffer material. The hard ball 47 with a spherical end surface on the sleeve 45 is made of hard material. When the pay-off roller 18 and the take-up roller 19 have finished rotating, the first push cylinder 16 6 The output end will push the connecting seat 29 upward, thereby pushing the hard block 48 and the sleeve 45 on the hard block 48 to press on the rubber ring 25, so that the rubber ring 25 and the pay-off roller 18 or the take-up roller 19 can be clamped and fixed. During this clamping and fixing process, the hard block 48 and the hard ball 47 can provide the necessary hard clamping pressure, and the sleeve 45 and the rubber ring 25 can absorb the shaking of the pay-off roller 18 and the take-up roller 19 during the clamping process, so that the pay-off roller 18 and the take-up roller 19 can be more stable when they are stopped as a whole, reducing shaking, so that the sheath wound on the outside will not be scattered.

[0041] During the process of the pay-off roller 18 and the take-up roller 19 taking up and paying out the wire, the drying assembly arranged on the second base 12 will dry and remove dust from the wound sheath tube to ensure that the overall storage performance of the sheath tube is improved.

[0042] A reinforcement tube 20 with through holes at both ends is provided between each second base 12 and the printer 11. When the sheath tube enters or exits the printer 11, it needs to pass through the reinforcement tube 20. The stabilizing component inside the reinforcement tube 20 will reinforce and prevent the sheath tube between the second base 12 and the printer 11 from shaking, so that the sheath tube will not shake excessively when printing inside the printer 11, thereby improving the printing quality.

[0043] A connecting pipe 21 is arranged on the end surface of each reinforcement pipe 20 near the pay-off roller 18, wherein the connecting pipe 21 between the printing machine 11 and the pay-off roller 18 is used to remove dust and dry the unprinted jacket pipe that is about to enter the printing machine 11, so as to reduce the influence of moisture and dust on printing, and the connecting pipe 21 between the printing machine 11 and the take-up roller 19 is used to dry the printed jacket pipe so that the printed font on the jacket pipe can be dried, wherein a corrugated water retaining ring 31 is arranged inside the connecting pipe 21 between the printing machine 11 and the pay-off roller 18, and the corrugated water retaining ring 31 is provided inside the connecting pipe 21 between the printing machine 11 and the pay-off roller 18. 1 has a plurality of inwardly concave bent inner circular surfaces, which will fit on the outer circular surface of the sleeve when the sleeve enters the interior of the reinforcement tube 20. Therefore, scraper rings 33 are arranged on the plurality of bent inner circular surfaces, so that the scraper rings 33 can scrape moisture and dirt on the outer circular surface of the sleeve in the moving state into the outwardly protruding bent groove on one side, and the cleaning can be effectively completed by scraping multiple times. In this process, the heating ring 35 arranged on one side of the scraper ring 33 at the back of the water retaining ring 31 will also be heated, so that the scraper ring 33 can be heated. The scraper ring 33 in the heated state can accelerate the evaporation of moisture on the outer circular surface of the sleeve, thereby improving the drying quality.

[0044] For further information, see Attachment Figure 3 and attached Figure 6 The reinforcing tube 20 and the first base 10 are fixed via a third base 26 , and a control panel 14 is provided on one side of the reinforcing tube 20 on the end surface of the bracket 13 .

[0045] Specifically, a plurality of bolt holes are provided on the third base 26 to facilitate the installation and fixation of the reinforcement pipe 20 . The staff can control the overall working efficiency of the equipment and the specific movement process through the control panel 14 .

[0046] For further information, see Attachment Fig.10 A plurality of rough surface particles 46 are arranged on the end surface of the sleeve 45 .

[0047] Specifically, the plurality of rough surface particles 46 are all made of hard material, which can effectively improve the surface contact friction and strength of the end face of the sleeve 45 , and can effectively improve the fixing effect on the pay-off roller 18 or the take-up roller 19 .

[0048] For further information, see Attachment Figure 1 , Attachment Figure 4 , Attachment Fig. 9 and attached Fig.12The drying component includes a first rotating seat 27 slidably arranged above the second base 12, a ventilation mesh pipe 41 is fixedly arranged in the first rotating seat 27, a connecting pipe port 50 is arranged on one end face of the ventilation mesh pipe 41, a hot air blower 15 is arranged on the end face of the second base 12 below the connecting pipe port 50, and the hot air blower 15 and the connecting pipe port 50 are connected to each other through a hose.

[0049] Specifically, a plurality of second pushing cylinders 17 are arranged on the end face of the second base 12, and the output ends of the plurality of second pushing cylinders 17 are connected to the bottom end face of the first rotating seat 27, so that the first rotating seat 27 can be pushed to move up and down, so that when the amount of sheath on the pay-off roller 18 or the take-up roller 19 above the first rotating seat 27 becomes less or more, the ventilation mesh pipe 41 can be pushed in real time to fit the outermost sheath surface and move. In the process of sheath winding, the hot air blower 15 will work, thereby generating hot air and blowing it to the connecting pipe port 50 through a hose. The connecting pipe port 50 will pass the hot air into the ventilation mesh pipe 41. A plurality of holes are arranged on the outer surface of the ventilation mesh pipe 41, so that the hot air can be evenly sprayed on the outside of the sheath, so that the sheath in the wound state can be dried. In this relationship, the ventilation mesh pipe 41 below the pay-off roller 18 plays a preliminary drying role, and the ventilation mesh pipe 41 below the take-up roller 19 plays a drying role for long-term storage of the sheath.

[0050] For further information, see Attachment Fig. 9 , Attachment Fig.12 and attached Fig.13 The drying component also includes a pressure roller 28 rotatably arranged on the outer circumferential surface of the ventilation mesh tube 41 , and a plurality of anti-skid grooves 52 are arranged on the outer circumferential surface of the pressure roller 28 , and a connecting opening 51 is arranged in each anti-skid groove 52 on the pressure roller 28 .

[0051] Specifically, the pressure roller 28 is made of elastic material and can be attached to the outside of the sheath tube in a rolled-up state, so as to clamp and fix the sheath in the rolled-up state. In this relationship, the pressure roller 28 is rotatably arranged on the outer cylindrical surface of the ventilation mesh tube 41, and can be driven to rotate by the sheath during the sheath rolling process, thereby avoiding the jamming of the sheath. The provision of multiple anti-slip grooves 52 effectively improves the surface roughness, thereby improving the limiting reinforcement effect. The multiple connecting openings 51 prevent the hot air ejected from the ventilation mesh tube 41 from being wrapped and blocked by the pressure roller 28, and can be sprayed on the outside of the sheath through the multiple connecting openings 51. This provision enables the drying component to not only further dry the sheath tube in the rolled-up state, but also reduce the occurrence of scattered sheath tubes.

[0052] For further information, see Attachment Figure 6 and attached Figure 7A heating seat 22 is arranged on the outer circumferential surface of the connecting pipe 21, a heating mesh plate 37 is arranged inside the heating seat 22, a plurality of air inlet tubes 24 are arranged on one side of the heating mesh plate 37 on the end surface of the heating seat 22, and a rotating fan wheel 38 is rotatably arranged inside the air inlet tube 24.

[0053] Specifically, the heating mesh plate 37 is in the prior art and can generate high temperature after being energized. A plurality of holes for ventilation are arranged on the end face. A driving motor 36 is arranged in the air inlet tube 24. A rotating fan wheel 38 is connected to the output end of the driving motor 36. When there is a sheath inside the connecting pipe 21, the output end of the driving motor 36 will drive the rotating fan wheel 38 to rotate, thereby driving external gas to enter the heating seat 22. The heating mesh plate 37 in the heating seat 22 is energized and heated, and the flowing gas can transfer heat to various places outside the sheath, thereby performing all-round heating treatment on the sheath.

[0054] For further information, see Attachment Figure 6 , Attachment Figure 7 and attached Figure 8 A plurality of connecting holes 34 are provided on the outer circumferential surface of the water retaining ring 31 below the heating seat 22 , and a drain port 30 is provided on the outer circumferential surface of the connecting pipe 21 below the water retaining ring 31 .

[0055] Specifically, the bellows-shaped water retaining ring 31 has both a concave surface and a convex surface, and a plurality of connecting holes 34 are evenly arranged on the convex surface. This arrangement allows, on the one hand, the dirt and sewage scraped to one side by the scraper ring 33 to be discharged downward through the connecting holes 34, and then collected by the drain port 30 and discharged outwardly. On the other hand, it facilitates hot air to flow to the outside of the sleeve through the plurality of connecting holes 34, thereby improving the overall drying quality of the sleeve entering the printing machine 11.

[0056] For further information, see Attachment Figure 7 and attached Figure 8 The stabilizing assembly includes a second rotating seat 39 slidably disposed inside the reinforcing tube 20 , and a plurality of first limiting rollers 40 are rotatably disposed inside the second rotating seat 39 .

[0057] Specifically, a third pushing seat 23 is provided on both sides of the outside of the reinforcement tube 20, and the output end of the third pushing seat 23 is connected to the second rotating seat 39. When the sheath enters the interior of the reinforcement tube 20, the output end of the third pushing seat 23 can push the second rotating seat 39, thereby pushing the multiple first limiting rollers 40 in the second rotating seat 39 to fit onto the outer cylindrical surface of the sheath tube, so that the sheath tube can be clamped and limited, so that the overall stability of the sheath tube is improved, and the printing accuracy is guaranteed. Embodiment 2:

[0058] Based on the first embodiment, further embodiments are made. Fig.10 and attached Fig.11Two limit plates 42 are arranged on the end faces of the connecting seat 29 on both sides of each sleeve 45, and a buffer block 49 is arranged on the end face of the limit plate 42 close to the sleeve 45. A third rotating seat 43 is arranged on the end face of the buffer block 49, and a plurality of second limit rollers 44 are rotatably arranged in the third rotating seat 43. The outer cylindrical surface of the second limit roller 44 can contact the outer wall surface of the unwinding roller 18 or the winding roller 19.

[0059] As a further embodiment, limiting plates 42 are provided on the end surfaces of the connecting seat 29 on both sides of the limiting disks of the pay-off roller 18 and the take-up roller 19. When the take-up roller 19 and the pay-off roller 18 are rotating, a plurality of second limiting rollers 44 rotatably arranged inside the third rotating seat 43 can contact with the outer end surface of the limiting disk, thereby performing rotation limiting processing on the limiting disk. During this process, when the pay-off roller 18 or the take-up roller 19 generates a certain vibration, the buffer block 49 on one side of the third rotating seat 43 can absorb the vibration, thereby improving the overall stability of the pay-off roller 18 or the take-up roller 19. In this scheme, the specific arrangement and number of the second limiting rollers 44 are not restricted, and they can be arranged without affecting the rotation of the pay-off roller 18 or the take-up roller 19. Embodiment three:

[0060] Further embodiments are made based on the first or second embodiment, and reference is made to the attached Figure 6 A plurality of guide grooves 32 are provided on the outer surface of the water retaining ring 31 between the plurality of connecting holes 34.

[0061] As a further embodiment, the setting of the water retaining ring 31 makes it difficult for the hot air to flow to various places inside the connecting pipe 21. The guide groove 32 can guide the hot air so that the hot air can flow to various places inside the connecting pipe 21, thereby improving the uniformity of heating and drying.
