Description

Technical Field

[0001] This utility model relates to the technical field of galvanizing production line equipment, and in particular to a device for improving the surface quality of sheet and strip products. Background Technology

[0002] Galvanized steel sheet is a welded steel sheet that has undergone galvanizing treatment. It has good corrosion resistance and weather resistance and is often used in the manufacture of metal components, building structures, automobiles, home appliances and other fields. As downstream industries increase their requirements for the surface precision and quality of galvanized steel sheet products, traditional metal rollers are prone to defects such as scratches, indentations and dents when they come into direct contact with the strip steel due to minor wear on the roller surface, impurity adhesion or hard contact.

[0003] After a hot-dip galvanizing line is shut down for maintenance, restarting it often results in iron oxide scale and zinc scale that easily stick to the rollers and are difficult to clean, directly affecting product quality and downstream customer use. Furthermore, when restarting after maintenance, the roller roughness and level must be checked and adjusted before operation. During startup, due to the high temperature of the steel plates exiting the zinc bath, slag easily adheres to the roller surface, causing damage that is difficult to remove. Manual cleaning of the roller surface by staff is necessary, posing a high risk factor and is cumbersome, time-consuming, and labor-intensive.

[0004] Therefore, those skilled in the art are dedicated to developing a device to improve the surface quality of sheet and strip products in order to solve the aforementioned problems. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is that when starting up the machine after shutdown and maintenance, it is necessary to check the roughness and level of the rollers first, and adjust them before starting up. During the start-up operation, due to the high temperature of the steel plate exiting the zinc pot, slag is easily stuck to the roller surface when it reaches the zinc pot tower, resulting in damage defects that are not easy to remove. It is necessary for the staff to manually clean the roller surface, which has a high risk factor and is cumbersome, time-consuming and labor-intensive.

[0006] To achieve the above objectives, this utility model provides a device for improving the surface quality of sheet and strip products, comprising: A roller assembly, which is rotatably mounted on a support base; A fabric layer is covered on the outer surface of the roller component; Two fixing components are respectively disposed on two end surfaces of the roller component and configured to fix the fabric layer in place; and A transmission component is connected to the rotating shaft of the roller component and is configured to drive the roller component to rotate.

[0007] Furthermore, the covering layer is made of one of the following: felt, non-woven fabric, cotton-linen blend, or chemical fiber.

[0008] Furthermore, the felt includes one of needle-punched felt and elastic felt.

[0009] Furthermore, the synthetic fiber includes fine-textured synthetic fiber.

[0010] Furthermore, the covering layer includes either a sleeve-type covering or a stitched-on covering.

[0011] Furthermore, the roller component is mounted on the support base via bearings.

[0012] Furthermore, each of the fixing components includes a chain and a limiting rod. The chain includes an inner ring chain, an outer ring chain, and a connecting chain. The inner ring chain is disposed around the axis of rotation of the roller component. The outer ring chain is disposed at the outer edge near the end surface of the roller component. The connecting chain extends radially along the roller component, is distributed circumferentially along the roller component, and connects the inner ring chain and the outer ring chain. The limiting rod is distributed circumferentially along the outer ring chain and fixed to the outer ring chain. The limiting rod is configured to fix the edge of the fabric layer located at the end of the roller component.

[0013] Furthermore, the transmission component includes a power source and a transmission body, the transmission body being disposed between the power source and the rotating shaft of the roller component, the power source including at least one of a motor and a reducer, the transmission body including one of a chain, a belt and a coupling, and the coupling including one of a rigid coupling and a flexible coupling.

[0014] Furthermore, it also includes a fit inspection component, which is fixedly connected to the support base. The fit inspection device includes a roller disposed facing the outer surface of the roller component and is configured to detect the fit between the fabric layer and the outer surface of the roller component.

[0015] Furthermore, it also includes a cleaning component comprising a scraper blade that extends axially along the roller component and is fixedly connected to the support base, the scraper blade being made of a polymer material.

[0016] The beneficial effects of this utility model are: 1. During normal production operations on a galvanizing line, a cloth is added to the surface of the rollers. This is mainly done by changing the characteristics of the roller surface (coefficient of friction, hardness, cushioning, etc.) to achieve the purpose of protecting and optimizing the processing effect or assisting the process. The cloth is soft and smooth, which can prevent the metal rollers from directly contacting the processed materials (such as zinc sheets, mud spots, fabrics, etc.), reducing defects such as scratches and indentations caused by roller surface wear, burrs or impurities. The cloth surface has a certain degree of roughness, which can increase the friction between the rollers and the materials, and prevent the materials from slipping during transmission or processing.

[0017] 2. The elasticity of the fabric can disperse the local pressure of the roller on the material, making the force more uniform. It is especially suitable for brittle or easily deformable materials (such as thin glass and soft plastics). The fabric can absorb dust, debris or excess media (such as grease and moisture) on the surface of the material, reducing the interference of impurities on the processing and indirectly improving product quality.

[0018] The following will further explain the concept, specific structure and technical effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model. Attached Figure Description

[0021] 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.

[0022] 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.

[0023] This invention provides a device for improving the surface quality of strip products and extending the service life of equipment rollers. This invention utilizes a covering fabric to wrap the surface of the equipment rollers, providing excellent protection, isolation, and cleanliness. The covering fabric is a component used in surface treatment equipment during the processing of metal sheets such as galvanized wire. Its working principle is mainly based on the contact between the flexible material (such as felt, non-woven fabric, nylon, special fibers, etc.) on the roller surface and the strip steel surface to achieve functions such as cleaning, polishing, and auxiliary coating. During installation, no operator support is required, and the installation operation is simple, saving time and effort.

[0024] The basic structure of this utility model consists of a metal roller core and an outer layer of flexible material (special fiber cloth or felt). The roller body is driven by a motor device to rotate, ensuring uniform contact between the strip steel and the surface.

[0025] like Figure 1-4 As shown, this embodiment provides an apparatus for improving the surface quality of strip products, including a roller component 1, a fabric covering layer 2, a fixing component 3, and a transmission component.

[0026] The roller component 1 is rotatably mounted on the support base 4.

[0027] Preferably, the roller component 1 can be mounted on the support base 4 via a bearing.

[0028] The support base 4 is made of high-strength and rigid materials, such as cast steel, and is connected and fixed to the galvanized wire frame to provide stable support for the bearing and roller assembly 1. The support base 4 is equipped with lubrication oil passages, installation and positioning structures, etc., to facilitate bearing installation, maintenance and lubrication, and to ensure the assembly accuracy and smooth rotation of the roller assembly 1.

[0029] Roller component 1 is a generally cylindrical roller body, made of a high-strength, wear-resistant and corrosion-resistant material through forging and processing.

[0030] The covering layer 2 is composed of a flexible covering material (usually felt, non-woven fabric, or other special fiber materials), which is covered on the outer surface of the roller component 1 to ensure uniform contact with the strip surface. It also protects the surface of the processed strip product, reduces damage, increases friction, prevents slippage, buffers pressure, and uniformly transmits force.

[0031] The function of the fabric layer 2 is to provide protection and isolation through the flexible material attached to its surface, preventing the strip steel from directly contacting the roller component 1 during operation and delaying wear and aging. It also prevents impurities such as zinc scale, zinc dross, and foreign matter from adhering to the roller surface during galvanizing production, thus avoiding surface scratches and bumps.

[0032] The flexible material of the covering layer 2 can buffer contact pressure and reduce surface damage caused by hard friction, thereby meeting the production requirements of high-quality strip products. At the same time, for the production of thin strip steel or low zinc coating products, the covering layer 2 can prevent zinc coating scratches or deformation caused by contact with metal roller components 1. In order to adapt to the production of such strip products, the covering layer 2 is installed to maintain the surface quality of the product. If the roller surface is dirty and needs to be cleaned, it is very convenient without stopping the machine, thereby improving the surface quality of the steel plate.

[0033] Preferably, considering durability, the fabric layer 2 is adjusted according to the thickness of the strip product and the contact pressure. When the thickness of the strip product is less than 0.5mm, a 3-5mm thick fabric layer 2 is selected. Too thin or too thick a layer will cause excessive pressure and deformation. For thicker specifications or high-tension production scenarios, a 5-10mm thick fabric layer 2 is selected to enhance the cushioning effect. For high-speed (greater than 100m / min) or continuous production scenarios, a fabric layer 2 made of abrasion-resistant fibers (polyester, nylon, etc.) is selected.

[0034] Preferably, considering compatibility, if cleanliness is the primary concern, a wrapping layer 2 made of highly nonwoven fabric or needle-punched felt is selected. The fiber structure is dense and has strong adsorption, which can avoid tiny impurities. A wrapping layer 2 made of highly soft cotton-linen blend or elastic felt is selected. The flexible texture can reduce contact pressure and prevent indentation or zinc layer damage to the strip. A wrapping layer 2 made of fine-textured chemical fiber is selected. The surface is flat and has good wear resistance, which can improve the micro-uneven shape defects on the surface of the strip and is suitable for the production of appliance panels and automotive panels with high surface quality requirements.

[0035] Preferably, considering economic efficiency, the covering layer 2 uses a quick-removable sleeve-type covering, which avoids the time-consuming replacement caused by glue adhesion; the covering layer 2 of the continuous hot-dip galvanizing line can be equipped with a stitched covering, which is more firmly fixed and can reduce the risk of falling off during operation; for products with lower surface quality requirements, the covering layer 2 made of cost-effective recycled fibers can be used; for the production of high-quality surface appliance panels or automotive panels, the covering layer 2 made of imported high-quality covering can be selected, which can avoid the generation of strip defects caused by shedding and damage.

[0036] Two fixing components 3 are respectively set on the two end surfaces of the roller component 1, and fix the two sides of the fabric layer 2 to prevent the fabric layer 2 from shifting from the roller component 1.

[0037] Each fixing component 3 includes a chain and a limiting rod 6. The chain, typically made of metal, secures the fabric layer 2 and completely covers the end surface of the roller component 1. This prevents the fabric layer from detaching, deforming, or shifting during galvanizing production. When galvanized steel sheet production occurs and one side of the fabric layer 2 is squeezed, the chain action enhances the protection against lateral displacement of the fabric layer 2.

[0038] Preferably, the chain body is made of high-quality 304 stainless steel with a diameter of 1.2mm, a load-bearing capacity of over 8kgf, and is easy to install and operate, with high safety and sturdiness.

[0039] The chain includes an inner ring chain 7, an outer ring chain 8, and a connecting chain 9. The inner ring chain 7 is arranged around the rotating shaft 5 of the roller component 1. The outer ring chain 8 is located at the outer edge of the end surface of the roller component 1. The connecting chain 9 extends radially along the roller component 1, is distributed circumferentially along the roller component 1, and connects the inner ring chain 7 and the outer ring chain 8. The inner ring chain 7, the outer ring chain 8, and the connecting chain 9 can be formed as a whole. A limiting rod 6 is distributed circumferentially along the outer ring chain 8 and fixed to the outer ring chain 8. The limiting rod 6 can fix the edge of the fabric layer 2 at the end of the roller component 1, so that the fabric layer 2 is completely in contact with the outer surface of the roller component 1 after installation. One end of the limiting rod 6 can be fixed to the outer ring chain 8 by welding or pressing, and the other end of the limiting rod 6 is fixed to the edge of the fabric layer 2 at the end of the roller component 1.

[0040] The transmission component is connected to the rotating shaft 5 of the roller component 1 and can drive the roller component 1 to rotate.

[0041] The transmission components include a power source and a transmission body. The transmission body is connected to the journal or extended shaft end of the roller component 1 to receive the power output from the power source and drive the roller component 1 to rotate, thereby realizing the transmission of strip steel in the galvanizing line. The power source (such as a motor, reducer, etc.) is connected to the roller component 1 through the transmission body (chain, belt, coupling, etc.).

[0042] The coupling can be a rigid coupling or a flexible coupling. When a rigid or flexible coupling is used, it can compensate for the installation error of the transmission system, buffer and reduce vibration, and ensure stable power transmission to the roller component 1, avoiding the impact of transmission shock on the running stability of the roller component 1 and the strip.

[0043] In some embodiments, a fitting inspection component is also included. The fitting inspection component is fixedly connected to the support base 4. The fitting inspection device includes a roller facing the outer surface of the roller component 1, which is made of special cast steel, and can detect the fitting degree between the fabric layer 2 and the outer surface of the roller component 1 in real time using a roller-type inspection method, which is convenient for operators to observe and adjust.

[0044] In some embodiments, a cleaning component is also included, which is a roller scraper blade made of a polymer material, preferably a special plastic. The scraper blade extends axially along the roller component 1 and is fixedly connected to the support base 4. Closing the scraper blade before starting the machine can effectively prevent impurities such as zinc scale and zinc dross from adhering to the outer surface of the fabric layer 2.

[0045] 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.
