Description

Technical Field

[0001] This utility model relates to the field of steel strip winding technology, specifically to a steel strip winding and decontamination device. Background Technology

[0002] In the steel processing and metal products manufacturing industry, steel strip, as an important basic material, is widely used in the manufacture of various products. During the production and processing of steel strip, its surface often becomes contaminated with various stains, such as oil, dust, and metal shavings. These stains not only affect the appearance quality of the steel strip but may also adversely affect subsequent processing techniques, such as reducing welding quality and affecting coating adhesion. Therefore, effective decontamination treatment of the steel strip before winding is essential.

[0003] Currently, existing steel strip decontamination methods have some significant shortcomings. While existing decontamination spray devices can rinse the steel strip surface to a certain extent, they lack a systematic decontamination process design. Residual moisture on the steel strip surface after cleaning cannot be removed promptly and effectively, leading to easy corrosion during the winding process due to moisture residue, severely affecting the quality and service life of the steel strip. Utility Model Content

[0004] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a steel strip winding and decontamination device that can clean, decontaminate, rinse and dry the steel strip, so that the wound steel strip can be better stored.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a steel strip winding and decontamination device, comprising:

[0006] A take-up roller, which is rotatably mounted on the frame;

[0007] The spray assembly, located in front of the take-up roll, includes two spray frames for spraying the upper and lower sides of the steel strip, respectively.

[0008] A dehumidification assembly, located between the spray assembly and the take-up roller, is used to dehumidify the sprayed steel strip. It includes a dryer and two dehumidification scrapers located on the upper and lower sides of the steel strip, respectively. The dryer has two air outlets, one on the upper side and one on the lower side of the steel strip, respectively.

[0009] Preferably, the take-up roller has a plurality of evenly distributed support plates on its circumferential surface, and the take-up roller is provided with a spreading mechanism for driving the support plates to move radially along the take-up roller.

[0010] Preferably, the spreading mechanism includes multiple drive shafts, which are rotatably mounted on the circumferential surface of the take-up roller via bearing seats, and the multiple drive shafts correspond one-to-one with the support plate; each drive shaft is provided with multiple telescopic units, one end of the telescopic unit is hinged to the support plate, and the other end is provided on the drive shaft. When the drive shaft rotates, the telescopic unit extends and retracts, driving the support plate to move radially along the take-up roller.

[0011] Preferably, the telescopic unit includes:

[0012] Two rotating sleeves, both of which are threaded into the drive shaft with opposite thread directions;

[0013] Two connecting rods are respectively hinged to two rotating sleeves, and the ends of the two connecting rods away from the rotating sleeves are hinged to the support plate through the same hinge axis.

[0014] Preferably, the drive shaft includes a plurality of sub-shafts connected in sequence, the number of which is the same as the number of telescopic units; the ends of two adjacent sub-shafts are connected by bushings, and the bushings are splined to the two sub-shafts.

[0015] Preferably, a toothed ring is rotatably mounted on the take-up roller, and a gear that meshes with the toothed ring is fixed at the end of the drive shaft. When the toothed ring rotates, it drives all gears to rotate synchronously.

[0016] Preferably, a guide rib is fixed on the support plate, a limit frame is fixed on the winding roller, and a limit groove is provided on the limit frame to cooperate with the guide rib.

[0017] Preferably, the side of the support plate away from the winding roller is provided with an arc-shaped support portion for abutting against the inner wall of the steel strip.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1:

[0033] like Figures 1 to 6 As shown, Embodiment 1 of this utility model provides a steel strip winding and decontamination device, including a winding mechanism, a spray assembly, and a dehumidification assembly. Figure 1 As shown, the take-up roller 1 is located at the end of the device. The steel strip passes through the spray assembly and the dehumidification assembly in sequence before being wound up by the take-up mechanism.

[0034] like Figures 2 to 6 As shown, the winding mechanism designed in this utility model includes a frame 2 and a winding roller 1 rotatably mounted on the frame 2. Eight support plates 11 are evenly arranged on the circumferential surface of the winding roller 1, and the length direction of these eight support plates 11 is parallel to the axial direction of the winding roller 1. Two limiting frames 112 are fixed on the winding roller 1, and eight limiting grooves 113 are opened on the limiting frames 112. Guide ribs 111 that slide and engage with the limiting grooves 113 are fixed on the support plates 11. Through the sliding engagement of the guide ribs 111 and the limiting grooves 113, the movement of the support plates 11 is guided, ensuring that the support plates 11 move radially along the winding roller 1, and avoiding the positional displacement of the support plates 11 from affecting the winding effect.

[0035] In order to increase the contact area between the support plate 11 and the steel strip, the present invention has an arc-shaped support part 114 fixed on the side of the support plate 11 away from the winding roller 1. The arc-shaped support part 114 can fit against the inner wall of the steel strip over a larger area, providing stable support for the steel strip roll, preventing the steel strip from deforming during the winding process, and ensuring the roundness of the steel strip roll.

[0036] To control the movement of the support plate 11, this invention provides a spreading mechanism on the take-up roller 1. The spreading mechanism includes eight drive shafts 12, which are rotatably mounted on the circumferential surface of the take-up roller 1 via bearing seats. Each drive shaft 12 corresponds to one support plate 11. Three telescopic units 13 are provided on each drive shaft 12, and the three telescopic units 13 are evenly distributed along the length of the support plate 11. Each telescopic unit 13 includes two rotating sleeves 131 threaded onto the drive shaft 12 and two connecting rods 132 respectively hinged to the two rotating sleeves 131. The threads on the drive shafts 12 corresponding to the two rotating sleeves 131 have opposite helical directions; therefore, when the drive rods rotate, the two rotating sleeves 131 in the same telescopic unit 13 will move relative to each other. The ends of the two connecting rods 132 furthest from the rotating sleeves 131 are hinged to the support plate 11 via the same hinge shaft 133. When the drive shaft 12 rotates, the two connecting rods 132 in the same telescopic unit 13 will rotate symmetrically about the hinge shaft 133, thereby driving the support plate 11 to move radially along the winding roller 1. This allows the position of the support plate 11 to be flexibly adjusted according to the inner diameter of the steel strip coil, making it convenient to wind up steel strip coils of different specifications.

[0037] like Figure 1 As shown, the spray assembly is located in front of the take-up roller 1 and includes two spray frames 3, one above the other. Each spray frame 3 is used to spray the upper and lower surfaces of the steel strip. Each spray frame 3 is equipped with multiple cleaning agent spray heads 31 and multiple clean water spray heads 32. The cleaning agent spray heads 31 are located in front, while the clean water spray heads 32 are located behind. The steel strip is first cleaned by the cleaning agent spray heads 31 and then rinsed by the clean water spray heads 32, removing dirt and cleaning agent together. Both the cleaning agent spray heads 31 and the clean water spray heads 32 are at an angle to the steel strip. This arrangement allows the sprayed cleaning agent and clean water to impact the steel strip surface at a certain angle, enhancing the cleaning effect and more effectively removing stains from the steel strip surface, ensuring that all parts of the steel strip are effectively cleaned.

[0038] Example 2

[0039] Based on Embodiment 1, the drive shaft 12 of this invention includes three sequentially connected sub-shafts 121. The number of sub-shafts 121 is the same as the number of telescopic units 13. Each sub-shaft 121 has a stepped structure, with threads formed on the larger diameter portion of the sub-shaft 121, facilitating the threaded installation of the rotating sleeve 131 onto the sub-shaft 121. The ends of two adjacent sub-shafts 121 are connected by a bushing 122. The inner wall of the bushing 122 is provided with a spline, and the ends of the sub-shafts 121 are provided with keyways. The bushing 122 engages with the two adjacent sub-shafts 121 via splines. This allows the rotation of one sub-shaft 121 to drive the other sub-shafts 121 to rotate synchronously via the bushing 122, resulting in more stable and reliable power transmission.

[0040] To drive all drive shafts 12 to rotate simultaneously, this invention features a gear ring 14 rotatably mounted on the take-up roller 1, and a gear 15 meshing with the gear ring 14 fixed at the end of each drive shaft 12. A motor (not shown in the attached diagram) is fixed on the take-up roller 1, and the drive gear 15 meshing with the gear ring 14 is fixed on the motor's output shaft. When the motor operates, it drives the gear ring 14 to rotate, which in turn drives all drive shafts 12 to rotate, achieving synchronous opening or closing of multiple support plates 11, further improving the stability and synchronicity of the winding process.

[0041] Example 3

[0042] Based on Embodiments 1 and 2, the dehumidification component designed in this invention is located between the spraying component and the winding roller 1, and is used to dehumidify the sprayed steel strip. Figure 1 As shown, the dehumidification assembly includes a dryer 4 and two desiccant blades 5 located on the upper and lower sides of the steel strip, respectively. The dryer 4 has two air outlets 41, located on the upper and lower sides of the steel strip, respectively. Each air outlet 41 is equipped with a cover to concentrate the airflow and direct it towards the steel strip. Nylon scraper strips 51 are bolted to the ends of the desiccant blades 5. These nylon scraper strips 51 are angled against the surface of the steel strip, allowing for better contact and effective removal of moisture. The dryer 4 then dries any remaining moisture on the steel strip, effectively preventing corrosion and other problems caused by residual moisture during winding.

[0043] In practical use, when the steel strip needs to be wound up and cleaned, the steel strip is first laid along the device and fixed on the support plate 11. Then, the winding roller 1 is rotated, and the steel strip begins to move. The spray assembly is activated, and the cleaning agent spray head 31 and the clean water spray head 32 spray and clean the upper and lower surfaces of the steel strip in a set sequence. After cleaning, the steel strip enters the dehumidification assembly, where the water removal scraper 5 removes moisture from the surface of the steel strip. The dryer 4 dries the steel strip, removing residual moisture, and the winding roller 1 winds up the steel strip. The arc-shaped support part 114 of the support plate 11 provides stable support for the steel strip roll, ensuring the winding quality.

[0044] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
