Description

Technical Field

[0001] This utility model relates to the technical field of galvanizing production line equipment, and in particular to a galvanizing production line roller cleaning device. Background Technology

[0002] The surfaces of tension rollers, guide rollers, and other rollers in galvanizing production lines often have zinc dross, iron oxide scale, foreign matter, and other deposits. Efficient cleaning of the rollers is necessary to prevent these deposits from being pressed into the surface of the strip steel.

[0003] Common roller cleaning methods include manual wiping and simple equipment cleaning. Manual wiping requires the production line to stop running and manual intervention to remove the deposits on the roller surface, which is not only labor-intensive and extremely inefficient, but also makes it difficult to guarantee the cleaning effect. Simple equipment cleaning, while improving cleaning efficiency to some extent, suffers from problems such as incomplete cleaning and inability to target stubborn stains, making it difficult to meet the requirements of modern galvanizing production for efficient and high-quality cleaning.

[0004] When using scraper blades to remove deposits from the roller surface, the blade angle and pressure rely on manual experience for adjustment, which is not only difficult to adjust but also results in a slow response time. Furthermore, due to the high hardness of zinc slag, the scraper blades wear easily, with a lifespan of less than 120 hours.

[0005] Therefore, those skilled in the art are dedicated to developing a convenient, effective, safe, and reliable roller cleaning device for galvanizing production lines, which is of great significance for improving product quality, reducing production costs, and extending the lifespan of roller equipment.

[0028] The following description, with reference to the accompanying drawings, illustrates several preferred embodiments of the present invention to make its technical content clearer and easier to understand. The present invention can be embodied in many different forms, and the scope of protection of the present invention is not limited to the embodiments mentioned herein.

[0029] In the accompanying drawings, components with the same structure are indicated by the same numerical designation, and components with similar structures or functions are indicated by similar numerical designations. The dimensions and thicknesses of each component shown in the drawings are arbitrary, and this invention does not limit the dimensions and thicknesses of each component. To make the illustrations clearer, the thickness of some components has been appropriately exaggerated in the drawings.

[0030] like Figure 1-3 As shown, this embodiment provides a roller cleaning device for a galvanizing production line, including a scraper blade 1, a connecting structure 2, an adjusting device 3, and a supporting structure 4.

[0031] The core component of the roller cleaning device is the scraper blade 1, which can be made of polymer materials (such as polyurethane, ultra-high molecular weight polyethylene or special engineering plastics, etc.), and has high strength, high toughness, high wear resistance, as well as impact resistance (to deal with hard impurities on the roller surface) and chemical stability (resistance to pressure and corrosion).

[0032] The scraper blade 1 is elongated and has opposing cutting edges and a blade body, with the cutting edges facing the outer surface of the roller 6 in the galvanizing production line. The cutting edges are designed as thin sheets or wedges to efficiently scrape away adhering substances (zinc dross, iron oxide scale, foreign matter, etc.) from the outer surface of the roller 5. A thin sheet cutting edge means that the scraper blade 1 is extremely thin, typically no more than 2.5 mm, with the two sides of the cutting edge parallel to each other; while a wedge-shaped cutting edge means that the two sides of the cutting edge form an angle with the center, typically between 15° and 30°.

[0033] The connecting structure 2 is detachably connected to the scraper blade 1, and is responsible for firmly connecting the scraper blade 1 to other parts and transmitting scraping force.

[0034] The connecting structure 2 includes a mounting strip made of metal and a drive end. The mounting strip is the same length as the scraper blade 1, and the drive end is connected to one end of the mounting strip. The blade body of the scraper blade 1 is detachably connected to the mounting strip.

[0035] In some embodiments, a buffer pad may be provided between the mounting strip and the blade body to reduce impact stress damage to the scraper blade 1.

[0036] like Figure 2-3 As shown, the overall length of the scraper blade 1 is L, the width is 20 mm, and the thickness is 2 mm. Nine sets of first mounting holes are evenly arranged along the length of the blade body. Each set of first mounting holes is a hole with a diameter of 6 mm and a vertical distance of 10 mm. The distance between the second set of first mounting holes and the first set of first mounting holes is A1, the distance between the third set of first mounting holes and the first set of first mounting holes is A2, and so on.

[0037] Accordingly, a second mounting hole is provided at the position corresponding to the blade body. The mounting strip and the blade body are fixed together by high-strength anti-loosening bolts passing through the first and second mounting holes. The high-strength anti-loosening bolts ensure a tight connection between the mounting strip and the blade body, preventing them from falling off due to vibration. The bolts are symmetrically distributed to ensure uniform force on the scraper blade 1.

[0038] The adjustment device 3 is connected to the connecting structure 2 and is used to flexibly adjust the contact pressure and angle between the scraper blade 1 and the roller 5 to meet the working requirements and different surface conditions of the roller 5.

[0039] The adjusting device 3 includes a handwheel 6, an input rod 7, and an output gear 8. The input rod 7 meshes with the output gear 8, and the axis of the input rod 7 is perpendicular to the axis of the output gear 8. The axis of the output gear 8 is parallel to or coincides with the axis of the drive end of the connecting structure 2. The output gear 8 is connected to the drive part of the connecting structure 2. The handwheel 6 is sleeved on the end of the input rod 7. The input rod 7 has external threads, forming a precision screw, and the output gear 8 is a helical gear.

[0040] The input rod 7 is also called a pinion or worm gear, and the output gear 8 is also called a worm wheel. The input rod 7 and the output gear 8 together form a worm gear transmission mechanism, which has a large transmission ratio and self-locking characteristics.

[0041] The support structure 5 can be made of metal or other materials to provide reliable support for the adjustment device 3, the connecting structure 2 and the scraper blade 1, and maintain their stability during operation.

[0042] In this embodiment, the support structure 5 is made of a metal frame (such as Q235 carbon steel or stainless steel square tube / channel steel) to provide rigid support.

[0043] In this embodiment, the main body of the support structure 5 is a gantry cantilever bracket, which spans above the roller 5 along the axial direction of the roller 5, and the bottom of the support structure 5 is fixed by anchor bolts.

[0044] The adjustment device 3 can be set on one side of the support structure 4.

[0045] In some embodiments, the support structure 4 may be provided with reinforcing ribs to improve bending resistance and prevent deformation caused by scraping force.

[0046] In use, tightening / loosening the handwheel 6 rotates the input lever 7, which in turn rotates the output gear 8 that meshes with it. The rotation of the output gear 8 can continuously and steplessly adjust the angle of the scraper blade 1, which is converted into a micron-level displacement of the scraper blade 1, thereby adjusting the contact pressure between the scraper blade 1 and the roller 5.

[0047] In this embodiment, the working angle of the scraper blade can be adjusted within an adjustable range of ±5°.

[0048] The roller cleaning device in this embodiment can be adjusted online without stopping the machine, adapting to different production conditions / roller surface conditions.

[0049] The improvement of the roller cleaning device in this embodiment is as follows:

[0050] The cleaning effect is achieved by using polymer scraper blades, and the scraping effect is precisely and stably controlled by a sophisticated adjustment device (especially the helical gear mechanism). Finally, the support structure provides robust support and connection, improving overall reliability and thus achieving efficient and long-lasting cleaning rollers, thereby enhancing the stability and efficiency of the production line.

[0051] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
