Description

Technical Field

[0001] The utility model relates to the technical field of loading racks, in particular to a loading rack of a shaftless loading device. Background Art

[0002] Automotive seals are typically composite materials, typically consisting of three layers: 20μm to 100μm thick nitrile rubber, a cold-rolled steel or stainless steel strip in the middle, and a non-stick coating (such as Teflon) on the back. Nitrile rubber with a thickness below 100μm is typically produced using a roller coating process. The entire roller coating line operates at a speed of 100 to 120 m / min, and a single 4,600-meter roll of nitrile rubber can be produced in just 40 to 50 minutes.

[0003] However, with the development of technology, the requirements for seals have gradually increased, resulting in the coating line requiring a length of 700-800 meters of nitrile rubber. In order to meet the needs of these small rolls of nitrile rubber, production costs will inevitably increase, and it will be impossible to achieve a production capacity advantage.

[0004] The shaftless rewinder purchased domestically was capable of separating large rolls into smaller ones. The entire roll weighed 500-600 kg, requiring a 6-inch paper core to support the nitrile rubber and prevent it from being squeezed. However, the large roll of liquid nitrile rubber was heavy and prone to rolling, making it unstable, making it difficult to place in the loading area of ​​the shaftless rewinder. Utility Model Content

[0005] In view of the above problems existing in the prior art, the utility model provides a loading rack of a shaftless loading device.

[0006] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0007] A loading frame of a shaftless loading device, comprising a supporting frame and supporting plates and supporting legs respectively arranged on opposite sides of the supporting frame;

[0017] The utility model has at least the following beneficial effects:

[0018] When the nitrile rubber coil is mounted on the loading rack of the present application, the loading rack can be first placed, and then the nitrile rubber coil is lifted and moved between the two supporting plates, and then the two ends of the paper core on the nitrile rubber coil are respectively placed on the two supporting plates, thereby completing the installation of the nitrile rubber coil on the loading rack. When the nitrile rubber coil is to be placed in the loading area of ​​the rewinder, the nitrile rubber coil can be directly loaded by moving the loading rack, which is easy to operate, can better prevent the nitrile rubber coil from rolling, and improves the stability of the nitrile rubber coil loading process.

[0024] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0025] like Figure 1-3 As shown, this embodiment provides a loading rack of a shaftless loading device, which includes a support frame 100, a supporting plate 200 and a support leg 300, wherein the supporting plate 200 and the support leg 300 are respectively arranged on opposite sides of the support frame 100, and the support leg 300 is in contact with the ground to support the above-mentioned support frame 100, and the nitrile rubber roll 10 can be placed on the supporting plate 200.

[0026] Furthermore, the number of supporting legs 300 is at least three and is evenly distributed on the support frame 100 to support the support frame 100. Preferably, the number of supporting legs 300 is four and is evenly distributed at the four corners of the support frame 100. The number of supporting plates 200 is at least two. For example, two supporting plates 200 are provided, and the two supporting plates 200 are spaced apart. The two ends of the paper core 11 of the nitrile rubber roll 10 can be respectively placed on the two supporting plates 200 to achieve the installation of the nitrile rubber roll 10 on the two supporting plates 200.

[0027] Furthermore, an arcuate groove 210 is formed inwardly on the side of the supporting plate 200 away from the supporting frame 100. The supporting plate 200 specifically supports the paper core 11 of the nitrile rubber roll 10 through the arcuate groove 210, thereby achieving the purpose of setting up the nitrile rubber roll 10.

[0028] It is understandable that, in the process of setting up the nitrile rubber coil 10 on the loading rack of the present application, the loading rack can be placed first, then the nitrile rubber coil 10 is lifted and moved between the two supporting plates 200, and then the two ends of the paper core 11 on the nitrile rubber coil 10 are respectively placed on the two supporting plates 200, thereby completing the setting up of the nitrile rubber coil 10 on the loading rack. When the nitrile rubber coil 10 is to be placed in the waiting loading area of ​​the rewinding machine, the mobile loading of the nitrile rubber coil 10 can be achieved directly by moving the loading rack, which is easy to operate, can better avoid the rolling of the nitrile rubber coil 10, and improve the stability of the loading process of the nitrile rubber coil 10.

[0029] In some embodiments, the diameter of the arc groove 210 on the support plate 200 is smaller than the diameter of the paper core 11 on the nitrile rubber roll 10. When the end of the paper core 11 on the nitrile rubber roll 10 is placed in the arc groove 210, the circumferential side wall of the paper core 11 does not contact the innermost side wall of the arc groove 210, that is, the two ends in the length direction of the arc groove 210 are in contact with the paper core 11, and the paper core 11 is supported by the cooperation of the two ends of the arc groove 210.

[0030] It is worth mentioning that because the paper core 11 on the nitrile rubber coil 10 is cylindrical, if the diameter of the arcuate groove 210 is equal to or larger than the diameter of the nitrile rubber coil 10, the paper core 11 is likely to roll to a certain extent in the arcuate groove 210 during the movement of the nitrile rubber coil 10, causing the nitrile rubber coil 10 to easily wobble, and there is a certain risk of the loading rack to topple over. By designing the diameter of the arcuate groove 210, the arcuate groove 210 can support the paper core 11 through two fulcrums, thereby effectively improving the stability of the paper core 11.

[0031] It is understandable that the cross-sectional shape of the arcuate groove 210 can be a regular circle or an irregular circle, as long as the two ends of the arcuate groove 210 in the longitudinal direction can form two fulcrums to support the paper core 11, and there is no special limitation on this.

[0032] In some embodiments, a rubber pad 220 is provided on a side edge of at least one end of the arc-shaped groove 210 in the length direction. Preferably, a rubber pad 220 is provided on both ends of the arc-shaped groove 210 in the length direction.

[0033] It can be understood that after the paper core 11 is placed on the arc groove 210, the two ends of the arc groove 210 in the length direction can contact the paper core 11 through the rubber pads 220 provided thereon, thereby increasing the friction between the paper core 11 and the arc groove 210, making it difficult for the paper core 11 to shake or roll on the arc groove 210, thereby improving the stability of the paper core 11 placed on the arc groove 210, and thus making it difficult for the nitrile rubber roll 10 to shake or roll on the loading rack, thereby improving the stability and safety of the nitrile rubber roll 10 during the loading process.

[0034] In particular, since the rubber pad 220 has a certain elasticity, it can protect the paper core 11 to a certain extent, preventing the paper core 11 from being deformed by force, and at the same time, it can also play a certain buffering effect under the impact of external force.

[0035] In some embodiments, the height of the support legs 300 provided on the support frame 100 is not less than the height of the supporting platform 21 of the hydraulic trolley 20 .

[0036] For example, in this embodiment, the height dimensions of the four legs 300 evenly arranged on the support frame 100 are all greater than or equal to the height of the supporting platform 21 of the hydraulic trolley 20. When the rewinder needs to be loaded, the supporting platform 21 of the hydraulic trolley 20 can be extended into the space formed by the four legs 300 under the support frame 100, and then the hydraulic trolley 20 is operated to raise the supporting platform 21 to lift the loading rack and the nitrile rubber coil 10 thereon. Then, by moving the hydraulic trolley 20, the loading rack and the nitrile rubber coil 10 can be driven to move, and then the loading rack and the nitrile rubber coil 10 can be moved to the loading area of ​​the rewinder. Then, the hydraulic trolley 20 is operated to lower the supporting platform 21, and finally the hydraulic trolley 20 is moved out.

[0037] In some embodiments, the support frame 100 includes a bottom frame 110 and a plurality of support columns 120 , wherein the support columns 120 and the legs 300 are respectively disposed on opposite sides of the bottom frame 110 . Furthermore, the support plate 200 is connected to the bottom frame 110 via at least two support columns 120 .

[0038] By setting the above-mentioned support column 120, on the one hand, the support function of the supporting plate 200 can be achieved, and on the other hand, the height requirement of the supporting plate 200 can be achieved, so that the supporting plate 200 has sufficient height to support the nitrile rubber roll 10.

[0039] Furthermore, a certain angle is formed between the support columns 120 and the bottom frame 110 , so that the cooperation between the multiple support columns 120 can improve the stability of the supporting plate 200 .

[0040] In some embodiments, a reinforcing rod 400 is provided between adjacent support columns 120. By connecting adjacent support columns 120 with the reinforcing rod 400, the stability of the fit between adjacent support columns 120 can be improved, and the structural strength can be increased to a certain extent, making the support of the support plate 200 more stable and safe.

[0041] In some embodiments, a support rod 500 is provided between the bottom frame 110 and the support column 120, or between the bottom frame 110 and the reinforcing rod 400, or between the bottom frame 110, the support column 120, and the reinforcing rod 400. By connecting the bottom frame 110 with the support column 120 and / or the reinforcing rod 400 through the support rod 500, the stability of the cooperation between the bottom frame 110, the support column 120, and / or the reinforcing rod 400 can be improved, and the structural strength can be improved to a certain extent, making the support of the supporting plate 200 more stable and safe.

[0042] In some embodiments, the height of the supporting plate 200 relative to the bottom frame 110 is set to be greater than the diameter of the nitrile rubber roll 10. This can be achieved by designing the height dimensions of the support legs 300, the bottom frame 110, the support columns 120, and the supporting plate 200.

[0043] It can be understood that by setting the height of the supporting plate 200 on the bottom frame 110, it can be better ensured that when the paper core 11 is placed in the arc groove 210, the nitrile rubber roll 10 can remain suspended, which can better prevent the nitrile rubber roll 10 from touching the bottom frame 110, thereby preventing the nitrile rubber roll 10 from being scratched.

[0044] In short, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention patent.
