[0041] like Figure 1-Figure 5 As shown, the present application discloses a pole roll delivery device 10. The pole roll delivery device 10 includes a pole roll 200, a pole roll delivery packaging structure 300 and a box structure 400.
[0042] The pole roll shipping packaging structure 300 includes a reel 310 and an isolation cover 320. The reel 310 is used to roll up the pole roll 200. The isolation cover 320 is inserted into the reel 310. The isolation cover 320 is used to cover the pole roll 200 rolled up on the reel 310. In the axial direction of the reel 310, the inner wall of the isolation cover 320 is spaced from the pole roll 200 rolled up on the reel 310.
[0043] In the pole roll shipping packaging structure 300, the pole roll 200 is rolled up by the reel 310, and the pole roll 200 wound up on the reel 310 is covered by the isolation cover 320 penetrated on the reel 310, so that the pole roll 200 wound up on the reel 310 is located in the isolation cover 320, and the pole roll 200 packaged by the pole roll shipping packaging structure 300 can be isolated and protected by the isolation cover 320. Therefore, the pole roll shipping packaging structure 300 can prevent the pole ears of the pole roll 200 from being damaged during the subsequent packaging and transportation process.
[0044] Moreover, in the above-mentioned pole roll shipping packaging structure 300, in the axial direction of the reel 310, the inner wall of the isolation cover 320 is spaced apart from the pole roll 200 wound on the reel 310, that is, in the axial direction of the reel 310, the inner wall of the isolation cover 320 is gap-matched with the pole ear of the pole roll 200 wound on the reel 310 (the pole roll 200 has two ends located in the axial direction of the reel 310, and at least one of the two ends has a pole ear), which can avoid the isolation cover 320 (specifically, it can be the end plate 322 described below) from directly contacting the pole ear of the pole roll 200, thereby preventing the pole ear of the pole roll 200 from being damaged.
[0045] In addition, when the pole roll 200 packaged with the above-mentioned pole roll shipping packaging structure 300 is placed in a vacuum bag for vacuum treatment, since the isolation cover 320 does not contact the pole ear of the pole roll 200 in the axial direction of the reel 310, it can be avoided that the pole ear of the pole roll 200 is deformed and excessive pressure is applied to the pole ear, thereby crushing the pole ear. This can prevent the pole ear of the pole roll 200 from being damaged by the influence of vacuum, thereby preventing the pole ear of the pole roll 200 from being damaged.
[0046] In some optional embodiments of the present application, in the radial direction of the reel 310, the inner wall of the isolation cover 320 is spaced from the pole coil 200 wound on the reel 310. In this way, the isolation cover 320 can be further prevented from directly contacting the pole lug of the pole coil 200, thereby preventing the pole lug of the pole coil 200 from being damaged. Moreover, when the pole coil 200 packaged by the pole coil shipping packaging structure 300 is placed in a vacuum bag for vacuum treatment, the isolation cover 320 can be further prevented from exerting excessive pressure on the pole lug of the pole coil 200 and crushing the pole lug, thereby preventing the pole lug of the pole coil 200 from being damaged due to the influence of vacuuming, thereby preventing the pole lug of the pole coil 200 from being damaged due to the influence of vacuuming, thereby preventing the loss of the pole coil 200.
[0047] In some optional embodiments of the present application, the isolation cover 320 includes two end plates 322 and a circumferential portion 324 connecting the two end plates 322. The two end plates 322 are arranged at intervals in the axial direction of the reel 310. In the axial direction of the reel 310, the end plate 322 is spaced apart from the end surface of the pole roll 200 wound on the reel 310. In the radial direction of the reel 310, the circumferential portion 324 is spaced apart from the outer peripheral surface of the pole roll 200 wound on the reel 310. In this way, it is not only convenient for the isolation cover 320 to be stably installed on the reel 310 through the two end plates 322, but also the structure of the isolation cover 320 itself can be made more stable. It can be understood that in some optional embodiments, the isolation cover 320 may include only one end plate 322, and the end plate 322 is arranged at one end of the circumferential portion 324.
[0048] In some optional embodiments of the present application, in the axial direction of the reel 310, the distance between the end plate 322 and the end surface of the pole roll 200 wound on the reel 310 is 5mm-50mm. In this way, the pole ears of the pole roll 200 can be prevented from being damaged due to the influence of vacuuming, and the size of the isolation cover 320 can be prevented from being too large.
[0049] In some optional embodiments of the present application, in the radial direction of the reel 310, the distance between the circumferential portion 324 and the outer peripheral surface of the pole roll 200 wound on the reel 310 is 5mm-50mm. In this way, it is possible to prevent the pole ears of the pole roll 200 from being damaged due to the influence of vacuuming, and to prevent the isolation cover 320 from being too large. Specifically, in some optional embodiments of the present application, in the radial direction of the reel 310, the distance between the outer peripheral surface of the end plate 322 and the outer peripheral surface of the pole roll 200 is 50mm-150mm. In this way, it is very convenient to achieve that in the radial direction of the reel 310, the distance between the circumferential portion 324 and the outer peripheral surface of the pole roll 200 wound on the reel 310 is 5mm-50mm.
[0050] In some optional embodiments, the isolation cover 320 is detachably connected to the reel 310. In this way, it is very convenient to disassemble and assemble the isolation cover 320. It can be understood that in some optional embodiments, the isolation cover 320 and the reel 310 can also be fixedly connected (non-detachably connected). For example, when the isolation cover 320 includes two half covers, and the two half covers can be spliced to form a complete isolation cover 320, one of the two half covers can be fixedly connected to the reel 310, and the other can be fixedly connected to the half cover.
[0051] Specifically, in some optional embodiments of the present application, the end plate 322 is detachably connected to the reel 310, and the two ends of the circumferential portion 324 are detachably connected to the two end plates 322. In this way, it is very convenient to realize the detachable connection between the isolation cover 320 and the reel 310. It can be understood that in some optional embodiments, when the isolation cover 320 includes two half covers, and the two half covers can be spliced to form a complete isolation cover 320, one of the two half covers can be detachably connected to the reel 310, and the other can be detachably connected to the half cover.
[0052] Specifically, in some optional embodiments of the present application, the end plate 322 has a mounting hole 322a. The end plate 322 is inserted through the mounting hole 322a on the reel 310. In this way, it is very convenient to realize the detachable connection between the end plate 322 and the reel 310, and the end plate 322 can be prevented from rotating on the reel 310. More specifically, in some optional embodiments of the present application, the end plate 322 and the reel 310 are both cylindrical, and the inner diameter of the mounting hole 322a of the end plate 322 is 5mm-15mm smaller than the outer diameter of the reel 310.
[0053] In some optional embodiments of the present application, the circumferential portion 324 includes a plurality of connecting rods 3242. The plurality of connecting rods 3242 are arranged at intervals along the circumference of the reel 310. That is, in some optional embodiments of the present application, the circumferential portion 324 is a discontinuous circumferential wall structure, so that the isolation cover 320 can have a relatively small weight. It can be understood that in some optional embodiments, the circumferential portion 324 can also be a continuous circumferential wall structure.
[0054] In some optional embodiments of the present application, the connecting rod 3242 is detachably connected to the end plate 322. In this way, it is very convenient to disassemble and assemble the isolation cover 320. It can be understood that in some optional embodiments, the connecting rod 3242 and the end plate 322 can also be fixedly connected (non-detachably connected). At this time, the end face of the connecting rod 3242 and the end plate 322 can be fixedly connected by gluing, and at this time, the end face of the connecting rod 3242 and the end plate 322 have an adhesive layer.
[0055] Specifically, in some optional embodiments of the present application, the end plate 322 has an installation opening 322b. The end of the connecting rod 3242 is inserted into the installation opening 322b with interference fit. In this way, during the installation process, it is possible to prevent the inconvenience caused to the packing personnel by the rotation of the connecting rod 3242, and it is very convenient to realize the detachable connection between the connecting rod 3242 and the end plate 322. More specifically, in some optional embodiments of the present application, the installation opening 322b is opened on the outer peripheral surface of the end plate 322 and penetrates the end surface of the end plate 322 close to the pole roll 200. In this way, the matching of the connecting rod 3242 and the end plate 322 can be an eccentric circle matching, that is, the connecting rod 3242 is located outside the center of the end plate 322, which is conducive to the outer side of the connecting rod 3242 being flush with the outer peripheral surface of the end plate 322, and can avoid the situation that the connecting rod 3242 protrudes outside the outer surface of the end plate 322 and causes the connecting rod 3242 to break the vacuum bag during vacuuming. Furthermore, during the installation process, the two end plates 322 may be installed on the reel 310 respectively so that the spacing between the two end plates 322 matches the length of the connecting rod 3242, and then the connecting rod 3242 is clamped in the installation opening 322b from the radial direction of the reel 310. Alternatively, the two end plates 322 may be installed on the reel 310 respectively so that the spacing between the two end plates 322 is greater than the length of the connecting rod 3242, and then one end of the connecting rod 3242 is plugged into one end plate 322, and finally the other end plate 322 is pushed toward the connecting rod 3242 so that the end plate 322 is plugged into the other end of the connecting rod 3242. More specifically, in some optional embodiments of the present application, the outer side of the connecting rod 3242 is flush with the outer peripheral surface of the end plate 322.
[0056] In some optional embodiments of the present application, the connecting rod 3242 is a connecting tube. That is, in some optional embodiments of the present application, the connecting rod 3242 is a hollow structure. In this way, the isolation cover 320 can have a relatively small weight. It can be understood that in some other optional embodiments, the connecting rod 3242 can also be a solid structure. It should be noted that when the connecting rod 3242 is a hollow structure, and the end face of the connecting rod 3242 is fixedly connected to the end plate 322 by gluing, a base can be inserted at the end of the connecting rod 3242 to increase the connection surface between the connecting rod 3242 and the end plate 322. At this time, there is an adhesive layer between the base and the end plate 322. Specifically, in some optional embodiments of the present application, the thickness of the adhesive layer can be 0.01mm-0.08mm.
[0057] Specifically, in some optional embodiments of the present application, the end plate 322 is a foam board. In this way, not only the weight of the isolation cover 320 can be reduced, but also the cost of the isolation cover 320 can be reduced. More specifically, in some optional embodiments of the present application, the foam board can be an EPE (Expandable Polyethylene, expandable polyethylene) board, EPS board (expandable polystyrene, expandable polystyrene), GPO (Grand Polystyrene beads (expandable), expandable polystyrene beads) board or EPO (Expandable Plocelan expandable polyethylene, styrene polymer) board, wherein the density of the foam board is 15g / cm 3 -45g / cm 3 . More specifically, in some optional embodiments of the present application, in the axial direction of the reel 310, the thickness of the end plate 322 is 15mm-100mm. In this way, not only the weight of the end plate 322 can be reduced, but also the end plate 322 can have better strength. Specifically, in some optional embodiments of the present application, the connecting rod 3242 is a PVC (Polyvinylchloride) tube. In this way, not only the weight of the isolation cover 320 can be reduced, but also the cost of the isolation cover 320 can be reduced.
[0058] In some optional embodiments of the present application, the pole roll shipping packaging structure 300 further includes a protective film 330. The protective film 330 is used to wrap the outer circumference of the pole roll 200 at least one circle along the circumference of the reel 310. In the axial direction of the reel 310, the end faces of the protective film 330 at both ends extend beyond the end faces of the pole roll 200 at both ends. In the axial direction of the reel 310, the end faces of the protective film 330 are in contact with or spaced apart from the inner wall of the isolation cover 320. In this way, not only can it be ensured that the inner wall of the isolation cover 320 is spaced apart from the end face of the pole roll 200, but the pole roll 200 can also be better protected. It can be understood that in some optional embodiments, the protective film 330 can also be omitted.
[0059] In some optional embodiments of the present application, in the axial direction of the reel 310, the distance between the end surface of the protective film 330 and the end surface of the corresponding pole roll 200 is greater than or equal to 20 mm. In this way, it is very convenient to achieve that in the axial direction of the reel 310, the distance between the end plate 322 and the end surface of the pole roll 200 wound on the reel 310 is 5 mm-50 mm.
[0060] In some optional embodiments of the present application, the protective film 330 coated on the outer circumference of the pole roll 200 is in contact with the outer circumference of the pole roll 200. In this way, the pole roll 200 can be better protected.
[0061] In some optional embodiments of the present application, in the circumferential direction of the winding drum 310, the circumferential surface of the protective film 330 is spaced from the inner wall of the isolation cover 320. In this way, the pole winding 200 can be better protected.
[0062] In some optional embodiments of the present application, the shipping packaging structure 300 is disposed in the box structure 400. The pole roll 200 is rolled up on the reel 310 of the pole roll shipping packaging structure 300.
[0063] Specifically, in some optional embodiments of the present application, the pole roll delivery device 10 further includes a vacuum bag. The pole roll 200 is rolled up on the reel 310 of the pole roll delivery packaging structure 300, and both the pole roll 200 and the pole roll delivery packaging structure 300 are contained in the vacuum bag.
[0064] Specifically, in some optional embodiments of the present application, the box structure 400 includes two fixing members. The two fixing members are respectively arranged corresponding to the two ends of the reel 310. The end of each reel 310 is fixed in the box structure 400 by a fixing member. More specifically, in some optional embodiments of the present application, the fixing member includes a lower partition 410 and an upper partition 420. The lower partition 410 and the upper partition 420 cooperate to fix the end of the reel 310 in the box structure 400.
[0065] When the pole roll delivery device 10 is working, the pole roll 200 is first rolled up on the reel 310, and then the protective film 330 is set on the pole roll 200. Then, the isolation cover 320 is passed through the reel 310 and the isolation cover 320 is set outside the pole roll 200 to complete the packaging of the pole roll 200. The packaged pole roll 200 is placed in a vacuum bag, and then the pole roll 200 placed in the vacuum bag is placed on the lower partition 410, and then the vacuum bag is vacuumed. After the vacuuming is completed, the upper partition 420 is fixed on the lower partition 410. Finally, the box structure 400 is sealed.
[0066] Specifically, in some optional embodiments of the present application, the box structure 400 also includes two limiters 430 located inside the box structure 400. In the axial direction of the reel 310, the two limiters 430 are respectively arranged corresponding to the two ends of the reel 310 to limit the displacement of the reel 310 in the axial direction of the reel 310. In this way, the pole reel 200 packaged with the pole reel shipping packaging structure 300 can be more stably accommodated in the box structure 400. Specifically, in some optional embodiments of the present application, the side of the limiter 430 close to the reel 310 is a flexible side. In this way, when the reel 310 is displaced and collides with the limiter 430, the limiter 430 can be effectively prevented from breaking the vacuum bag outside the reel 310. Specifically, in some optional embodiments of the present application, the limiting member 430 includes a hard block (eg, a wooden block) disposed on the box structure 400 and a soft block (eg, foam) disposed on a side of the hard block close to the reel 310 .
[0067] Specifically, in some optional embodiments of the present application, the box structure 400 further includes two support members 440 located in the box structure 400. The two support members 440 are respectively located below the two stop members 430 to support the box wall of the box structure 400. In this way, the box wall of the box structure 400 with a relatively thin thickness can also have a good supporting strength, and it is more convenient to install the tongue buckle 460 at the connection between the box wall of the box structure 400 and the base 450.
[0068] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0069] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent.
