Description

Technical Field

[0001] This utility model relates to a foreign object cleaning device for submerged roller grooves, belonging to the technical field of cold-rolled strip steel production equipment in the metallurgical industry. Background Technology

[0002] Tin-plated steel sheets are environmentally friendly and non-toxic, possessing excellent corrosion resistance, weldability, and the beautiful appearance unique to tin. They are primarily used in food and beverage packaging, pharmaceutical packaging, aerosol cans, general cans, chemical cans, and electronic stamping parts. Before tin plating, the raw substrate, after cold rolling, requires annealing to determine the mechanical properties of the cold-rolled strip. However, before annealing, the surface needs to be degreased and cleaned to remove rolling oil. During the cleaning process, to ensure thorough cleaning and straight running of the strip, a grooved immersion roller is used on the production line. However, because the immersion roller has grooves, foreign objects easily get stuck in the grooves, causing surface scratches on the strip. This defect can only be eliminated by cleaning and wiping the rollers on the production line.

[0003] There are two methods for using grooved immersion rollers: one is to fully immerse them in the bath solution, and the other is to partially immerse them. There are generally two methods for treating contaminated roller marks on online rollers: one is to stop the machine, which increases start-up and shutdown costs and reduces machine-hour output; the other is to start the machine and reduce the speed, lowering the normal operating speed from 300 m / min to 100 m / min, and then cleaning the roller grooves with a sharp object. This method poses safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide a foreign object cleaning device for submerged roll grooves, which can clean foreign objects in the submerged roll grooves online during the production of cold-rolled strip steel, thus solving the problems existing in the background technology.

[0005] The technical solution of this utility model is:

[0006] A foreign object cleaning device for a submerged roller groove includes hooks, a first support sleeve, a handwheel, a support rod, and a second support sleeve. The support rod is located directly above the submerged roller, and the support rod is provided with several hooks that cooperate with the grooves on the submerged roller. One end of the support rod is provided with the first support sleeve and the handwheel, and the other end of the support rod is provided with the second support sleeve.

[0007] The number of hooks is the same as the number of grooves on the immersion roller.

[0008] The upper end of the hook is fixed to the support rod, and the lower end of the hook is provided with a hook that matches the groove on the immersion roller.

[0009] The first support sleeve and the second support sleeve are symmetrically arranged at both ends of the support rod.

[0010] The first and second support sleeves are rotatably connected to the support rod.

[0011] A lock nut that cooperates with the handwheel is provided between the support sleeve and the handwheel.

[0012] Using this invention, during normal production, the hook head stays away from the groove on the immersion roller and does not come into contact with it. When foreign objects appear in the groove on the immersion roller, the handwheel is turned to make the hook head fit snugly against the groove on the immersion roller, and the hook at the lower end of the hook head is used to hook the foreign objects out of the groove.

[0013] The beneficial effects of this utility model are: during the production of cold-rolled strip steel, foreign objects in the grooves of the submerged rolls can be cleaned online, avoiding the formation of dents on the surface of the strip steel, reducing production capacity losses caused by downtime, and reducing safety hazards.

[0016] The markings in the diagram are as follows: Immersion roller 1, hook head 2, support sleeve one 3, handwheel 4, lock nut 5, support rod 6, support sleeve two 7. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and examples.

[0018] See attached document Figure 1 , 2 A foreign object cleaning device for a submerged roller groove includes hooks 2, a first support sleeve 3, a handwheel 4, a support rod 6 and a second support sleeve 7. The support rod 6 is located directly above the submerged roller 1. The support rod 6 is provided with a plurality of hooks 2 that cooperate with the grooves on the submerged roller 1. One end of the support rod 6 is provided with the first support sleeve 3 and the handwheel 4, and the other end of the support rod 6 is provided with the second support sleeve 7.

[0019] In this embodiment, refer to the appendix Figure 1 , 2 The immersion roller 1 is partially immersed in the bath liquid, and the support rod 6 is located directly above the immersion roller 1. The hooks 2 on the support rod 6 correspond one-to-one with the grooves on the immersion roller 1. The upper end of the hook 2 is fixed to the support rod 6, and the lower end of the hook 2 is provided with a bend that cooperates with the grooves on the immersion roller 1.

[0020] Support sleeve 1 (3) and support sleeve 2 (7) are symmetrically arranged at both ends of support rod 6, and support rod 6 can rotate within support sleeve 1 (3) and support sleeve 2 (7). A lock nut 5 that cooperates with handwheel 4 is provided between support sleeve 1 (3) and handwheel 4.

[0021] The working principle is as follows:

[0022] During normal production, hook 2 is away from the groove on the immersion roller 1 and does not come into contact with the groove. When foreign objects appear in the groove on the immersion roller 1, the operator turns the handwheel 4 to make hook 2 close to the groove on the immersion roller 1, and uses the hook at the lower end of hook 2 to hook the foreign objects out of the groove.
