Description

Technical Field

[0001] The utility model relates to the technical field of steel coil processing, in particular to a steel coil coating device. Background Art

[0002] Currently, in the steel coil production process, to avoid flattening the embossed steel coil surface, the coil ends are often passed through a laminating machine before entering a flattening machine. To facilitate storage and use of protective film, the film is often wrapped around a paper roll to form a protective film roll. Therefore, laminating machines are equipped with an unwinding mechanism to accommodate and unwind the protective film roll. Existing unwinding mechanisms typically consist of a positioning frame and an unwinding shaft, which is rotatably mounted on the positioning frame. When installing the protective film roll, the paper roll is tightly fitted onto the unwinding shaft for smooth unwinding.

[0003] Because most existing unwinding shafts are rollers with awkward outer diameters (e.g., those disclosed in Chinese Patent Publication No. CN210062311U), and the paper roll must be tightly fitted onto the unwinding shaft, the process of fitting the paper roll onto the unwinding shaft is cumbersome, especially during the initial installation. This significantly inconveniences the installation of the protective film roll. Furthermore, the limited structural strength of the paper roll means that the ends of the paper roll can easily fold inward during installation, further compromising the ease of installing the protective film roll.

[0004] Therefore, it is very necessary to design a steel coil coating device that can solve the above-mentioned technical problems. Utility Model Content

[0022] like Figures 1 to 4As shown, the steel roll coating device described in the present invention includes a frame 1, a coating roller assembly 2, a reeling shaft 3, and a swing positioning mechanism 4, wherein the coating roller assembly 2 is arranged on the frame 1, one end of the reeling shaft 3 can be rotatably arranged on the frame 1, and a positioning convex ring 31 is provided on the outer circumferential surface of one end of the reeling shaft 3, and a small shaft portion 32 is provided on the end face of the other end of the reeling shaft 3, and a guiding cone 33 extending to the small shaft portion 32 is provided on the corner of the other end of the reeling shaft 3, and the outer end of the small shaft portion 32 is a frustum end 34 with a small outside and a large inside, and the swing positioning mechanism 4 is arranged on the frame 1, and a sleeve hole 41 matching the frustum end 34 is opened on the swinging end of the swing positioning mechanism 4, and the sleeve hole 41 can make a reciprocating motion away from and close to the frustum end 34 with the swinging of the swinging end of the swing positioning mechanism 4, and also make the sleeve hole 41 relatively rotatable sleeved on the frustum end 34.

[0023] This steel roll coating device features a small shaft portion 32 on the other end of the unwinding shaft 3, a guiding tapered surface 33 extending from the small shaft portion 32 at the corner of the other end, and a truncated cone 34 with a smaller outer end and a larger inner end. This not only greatly facilitates fitting the paper roll end onto the unwinding shaft 3 but also reduces the chance of the end folding during the fitting process, significantly improving the convenience of installing the protective film roll.

[0024] By providing a positioning protrusion 31 on the outer circumferential surface of one end of the unwinding shaft 3, the positioning protrusion 31 can quickly and accurately define the installation position of the protective film roll, thereby improving the convenience and accuracy of the installation and positioning of the protective film roll.

[0025] By setting the swing positioning mechanism 4, not only can the other end of the unwinding shaft 3 be accurately and stably positioned, but the swing positioning mechanism 4 can also be prevented from affecting the installation process of the protective film roll. Such a steel roll coating device can have very high reliability and applicability.

[0026] like Figure 1 and Figure 4As shown, the swing positioning mechanism 4 includes a swing rod body 42, a limit rod 43, a locking screw 44, and a limit block 45. One end of the swing rod body 42 is hinged to the frame 1, and the set hole 41 is opened on the other end of the swing rod body 42. The limit rod 43 and the limit block 45 are respectively arranged on both sides of the swing direction of the swing rod body 42, and the limit block 45 is fixed to the frame 1. One end of the limit rod 43 is also hinged to the frame 1, and the limit rod 43 is enabled to swing in and out of the swing area of the swing rod body 42. The locking screw 44 is screwed on the limit rod 43, and the locking screw 44 can clamp and position the swing rod body 42 together with the limit block 45. Such a swing positioning mechanism 4 is very reliable. When the swing rod 42 is clamped and positioned by the locking screw 44 and the limit block 45, the sleeve hole on the swing rod 42 is sleeved on the truncated cone end 34, thereby achieving the purpose of stably positioning the unwinding shaft 3. Such a swing positioning mechanism 4 is very reliable. Moreover, such a swing positioning mechanism 4 is very convenient to operate, which helps to improve the convenience of use.

[0027] The other end of the limiting rod 43 can swing in and out of the swing range of the swinging rod body 42. The locking screw 44 is screwed onto the other end of the limiting rod 43. When the other end of the limiting rod 43 swings into the swing range of the swinging rod body 42, the limiting rod 43 prevents the swinging rod body 42 from swinging away from the limiting block 45. At this time, the locking screw 44 presses against the surface of the swinging rod body 42 away from the limiting block 45. This not only ensures the normal swinging of the swinging rod body 42 and the limiting rod 43, but also helps to stably limit the swinging rod body 42, thus meeting the needs of practical use.

[0028] like Figure 4 As shown, the sleeve hole 41 is formed by the inner hole of a bearing 411 embedded in the swing rod body 42. The inner hole of the bearing 411 is a tapered hole that matches the truncated cone end 34. This allows the unwinding shaft 3 to rotate very smoothly, thereby improving the reliability and applicability of the steel coil coating device.

[0029] like Figure 4 As shown, a hand wheel portion 46 is provided on the outer end of the locking screw 44. This can improve the convenience of locking and unlocking the locking screw 44, thereby helping to improve the convenience of use.

[0030] like Figures 1 to 4As shown, the frame 1 includes a support frame 11 and a sliding frame 12. The support frame 11 is provided with an adjustment screw 13. The sliding frame 12 is horizontally slidably arranged on the support frame 11 and is screwed to the adjustment screw 13. The film rolling assembly 2 is arranged on the support frame 11, one end of the unwinding shaft 3 is rotatably arranged on the sliding frame 12, and the swing positioning mechanism 4 is arranged on the sliding frame 12. In this way, the position of the unwinding shaft 3 can be adjusted, which not only can achieve the purpose of correcting component processing and assembly errors, but also can facilitate matching the position of the steel coil, thereby better meeting the needs of actual use.

[0031] like Figure 4 As shown, the sliding frame 12 and the supporting frame 11 are arranged to slide horizontally via a linear slide rail 121 , which can meet the requirements of stable assembly and sliding.

[0032] like Figure 4 As shown, an adjusting hand wheel 131 is provided on the end of the adjusting screw rod 13. This can improve the convenience of adjusting the adjusting screw rod 13, thereby helping to improve the convenience of use.

[0033] like Figure 1 and Figure 2 As shown, the laminating roller assembly 2 includes a lifting frame 21, a lower laminating roller 22, an upper laminating roller 23, and at least one lifting cylinder 24. The lifting cylinder 24 is vertically mounted on the support frame 11. The lifting frame 21 is vertically slidably mounted on the support frame 11 and is drivably connected to the lifting cylinder 24. The lower laminating roller 22 is rotatably mounted horizontally on the support frame 11. The upper laminating roller 23 is horizontally arranged above the lower laminating roller 22 and is rotatably connected to the lifting frame 21. The upper laminating roller 23 and the lower laminating roller 22 are parallel to each other and can reciprocate away from and toward the lower laminating roller 22 under the drive of the lifting cylinder 24. Such a laminating roller assembly 2 can not only coat steel coils of different thicknesses, but also adjust the laminating pressure, thereby facilitating the achievement of different laminating effects and further improving the applicability of the steel coil laminating device.

[0034] like Figure 1As shown, a support bracket 5 that can swing up and down is hinged on the side wall of the support frame 11, and the support bracket 5 is located on the input side of the coating roller assembly 2. A number of horizontally arranged support rollers 51 are provided on the top surface of the support bracket 5, and the support rollers 51 are parallel to each other. A driving cylinder 52 is arranged below the support bracket 5, and the two ends of the driving cylinder 52 are respectively hinged to the side wall of the support frame 11 and the bottom of the support bracket 5. This allows the steel coil to enter the coating roller assembly 2 more smoothly, thereby helping to improve the stability of the coating and, in turn, the quality of the coating. By driving the support bracket 5 to swing by the driving cylinder 52, it is possible to free up operating space on the side of the steel coil coating device, which not only facilitates the placement of the protective film coil, but also facilitates maintenance operations. This helps to further improve the applicability of the steel coil coating device.

[0035] like Figure 1 As shown, in the actual manufacturing process, the highest point of each supporting roller 51 and the highest point of the lower coating roller 22 are in the same horizontal plane, which can help the steel coil enter the coating rolling assembly 2 more smoothly, thereby further improving the coating quality.

[0036] like Figure 1 As shown, the support frame 11 is provided with a guide roller 14, and the guide roller 14 is located between the unwinding shaft 3 and the rolling portion of the film rolling assembly 2. The guide roller 14 can be used to guide the protective film, which can greatly reduce the influence of the film rolling assembly 2 on the installation position of the unwinding shaft 3, thereby facilitating the installation and positioning of the unwinding shaft 3.

[0037] like Figure 1 As shown, in actual use, the protective film roll 10 is mounted on the unwinding shaft 3, so that the end of the protective film 101 on the protective film roll 10 passes around the guide roller 14 and enters between the lower coating roller 22 and the upper coating roller 23. When the steel coil enters between the lower coating roller 22 and the upper coating roller 23, the protective film roller can be pressed onto the steel coil, thereby meeting the coating requirements.

[0038] like Figure 3 As shown, one end of the unwinding shaft 3 passes through the sliding frame 12, and a counterweight wheel 35 is mounted on the end of the unwinding shaft 3 that passes through the sliding frame 12. When the swing positioning mechanism 4 swings away from the other end of the unwinding shaft 3, the counterweight wheel 35 can offset the gravity exerted on the other end of the unwinding shaft 3, so that the unwinding shaft 3 can be stably maintained in a horizontal state, thereby reducing the probability of deformation of related components and further improving the reliability of the steel coil coating device.

[0039] like Figure 1As shown, a support frame 6 is provided on the side of the output end of the laminating roller pressing assembly 2. A plurality of horizontally arranged support rollers 61 are provided on the top surface of the support frame 6, and the support rollers 61 are arranged parallel to each other. This allows the laminating steel coil to be received horizontally, thereby ensuring a very smooth transfer of the steel coil to avoid adverse effects on the lamination, which helps to improve the lamination quality.
