Description

Technical Field

[0001] This utility model relates to the technical field of pre-degreasing devices, and more specifically, to a pre-degreasing device for hot-dip galvanized structural parts. Background Technology

[0002] During the production of metal structural parts, the distribution of grease on the surface is often uneven. Pre-degreasing devices can treat the workpiece surface comprehensively and evenly through spraying and brushing, reducing the grease content to a relatively uniform level. This allows the workpiece surface to react evenly with the acid and zinc liquids in subsequent pickling and galvanizing processes, ensuring the uniformity of the coating thickness and performance, and improving the overall quality stability of the product.

[0003] A search revealed that publication number CN118773621A discloses a pre-degreasing and pickling device for galvanized hardware parts, relating to the field of hardware processing technology. This degreasing and pickling device includes a base, a treatment tank, a circulating conveyor mechanism, and an oval guide support plate. It also includes the oval guide support plate and multiple storage mechanisms. The treatment tank is internally divided into cavities by multiple partitions, each cavity containing a rotary drive unit. Each storage mechanism includes a movable rod and a perforated mesh frame. When the storage mechanism is inside the treatment tank, the perforated mesh frame is connected to the rotary drive unit. When the perforated mesh frame moves horizontally and is connected to the rotary drive unit, the rotary drive unit can drive the perforated mesh frame to rotate. This invention has a simple structure, allowing multiple sets of hardware parts to undergo simultaneous degreasing and pickling treatment by rotation, resulting in high efficiency and significant degreasing and pickling effects. The storage mechanisms are reusable, making it highly practical. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Existing flushing-type pre-degreasing devices cannot perform deep degreasing cleaning on galvanized objects with porous surfaces. After cleaning, a certain amount of grease still accumulates in the pores of the galvanized object. During the next galvanizing, the zinc layer cannot adhere to the pores, resulting in substandard galvanized object quality and waste. Furthermore, most traditional pre-degreasing devices cannot perform precise cleaning on complex curved surfaces such as automotive parts because the distance between the cleaning brush and the galvanized object remains unchanged.

[0005] Therefore, a pre-degreasing device for hot-dip galvanized structural parts is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pre-degreasing device for hot-dip galvanized structural parts to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pre-degreasing device for hot-dip galvanized structural parts, comprising a sliding mechanism, a brush mechanism, and a displacement assembly. The brush mechanism is installed below the displacement assembly, and the displacement assembly is placed below the brush mechanism. The sliding mechanism includes a threaded assembly and a limiting assembly, and the limiting assembly is installed on the side of the threaded assembly. The brush mechanism includes a conveying assembly, a mounting groove, and a cleaning brush. The outer wall surface of the conveying assembly is equipped with a mounting groove, and the cleaning brush is installed below the mounting groove.

[0008] Preferably, the displacement assembly includes a first connecting plate, a second connecting plate, a telescopic rod, and an electric lifting rod, wherein the second connecting plate is installed above the first connecting plate, the telescopic rod is installed above the second connecting plate, and the electric lifting rod is installed above the telescopic rod.

[0009] Preferably, the conveying assembly includes a second motor, a first rotating shaft, a roller, and a conveyor belt, wherein the first rotating shaft is mounted on the side of the second motor, the roller is mounted on the outer diameter surface of the first rotating shaft, and the conveyor belt is placed on the outer diameter surface of the roller.

[0010] Preferably, the threaded assembly includes a first motor, a connecting shaft, and a threaded rotating shaft, wherein the connecting shaft is mounted on the side of the first motor, and the threaded rotating shaft is mounted on the side of the connecting shaft away from the first motor.

[0011] Preferably, the limiting component includes a slider, a groove, and a limiting plate, wherein the slider has a groove on its side and a limiting plate is installed on the top of the slider.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. Compared with the prior art, this pre-degreasing device for hot-dip galvanized structural parts can adjust the distance between the brush mechanism and the object to be galvanized through the displacement component, so that the brush mechanism can clean the oil stains on the surface of the object more precisely. Moreover, because the displacement component can adjust the vertical position of the brush mechanism, the brush on it can perform deep brushing on the cavity object or the object with holes on the surface, reducing the quality defects of the product in the galvanizing process caused by the internal holes of the object to be galvanized not being effectively cleaned.

[0014] 2. Compared with existing technologies, this pre-degreasing device for hot-dip galvanized structural parts adopts a quick-disassembly structure for easily damaged parts such as brushes, making its replacement time shorter than that of traditional equipment. When a single brush wears out, the worker can also remove the mounting slot of the brush separately and replace it with a new mounting slot containing a intact brush, thus achieving rapid replacement of damaged parts without stopping the machine to replace the entire transmission chain. Furthermore, because the brush can directly contact the oil stains, the amount of degreasing agent used when cleaning the surface of the object is reduced, and the cost of waste liquid treatment is also reduced.

[0022] 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.

[0023] Example 1

[0024] As attached Figures 1 to 6 The device shown is a pre-degreasing device for hot-dip galvanized structural parts, including a sliding mechanism 1, a brush mechanism 2 and a displacement component 3. The brush mechanism 2 is installed below the displacement component 3. The sliding mechanism 1 includes a threaded component 4 and a limiting component 5. The limiting component 5 is installed on the side of the threaded component 4. The brush mechanism 2 includes a conveying component 6, a mounting groove 7 and a cleaning brush 8. The mounting groove 7 is installed on the outer wall surface of the conveying component 6, and the cleaning brush 8 is installed below the mounting groove 7.

[0025] Specifically: When pre-degreasing treatment is required for hot-dip galvanized structural parts, the worker first fixes the object on the limiting component 5, then adjusts the distance between the brush mechanism 2 and the object through the displacement component 3, and then moves the position of the limiting component 5 through the threaded component 4 of the sliding mechanism 1, so that the object above the limiting component 5 also moves horizontally. During the horizontal movement of the object, the conveying component 6 of the brush mechanism 2 will drive the cleaning brush 8 on the mounting groove 7 to clean the object on the limiting component 5. During the cleaning process of the cleaning brush 8, the worker also needs to open the degreasing agent nozzles on both sides of the sliding mechanism 1 so that the exposed surface of the object can be evenly sprayed with degreasing agent during the movement.

[0026] Example 2

[0027] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 6 As shown below, see details:

[0028] In a preferred embodiment, the displacement assembly 3 includes a first connecting plate 9, a second connecting plate 10, a telescopic rod 11, and an electric lifting rod 12. The second connecting plate 10 is bolted to the top of the first connecting plate 9, the telescopic rod 11 is bolted to the top of the second connecting plate 10, and the electric lifting rod 12 is bolted to the top of the telescopic rod 11. When the worker adjusts the height of the brush mechanism 2, the electric lifting rod 12 will drive the second connecting plate 10 to move vertically through the telescopic rod 11. The second connecting plate 10 and the first connecting plate 9 are fixed by bolts, so when the second connecting plate 10 moves vertically, the first connecting plate 9 will also move vertically, and the brush mechanism 2, which is connected to the first connecting plate 9 through a bearing, will also move vertically.

[0029] In a preferred embodiment, the conveying assembly 6 includes a second motor 13, a first rotating shaft 14, a roller 15, and a conveyor belt 16. The first rotating shaft 14 is welded to the side of the second motor 13, and the roller 15 is welded to the outer diameter surface of the first rotating shaft 14. The conveyor belt 16 is placed on the outer diameter surface of the roller 15. The second motor 13 drives the roller 15 on its outer diameter surface to rotate through the first rotating shaft 14. The roller 15 drives the conveyor belt 16 to rotate on its outer diameter surface through friction. When the conveyor belt 16 rotates, the mounting groove 7 fixed to its surface by bolts and the cleaning brush inside it will also move horizontally to clean the objects on the limiting assembly 5.

[0030] In a preferred embodiment, the threaded assembly 4 includes a first motor 17, a connecting shaft 18, and a threaded rotating shaft 19. The connecting shaft 18 is welded and installed on the side of the first motor 17, and the threaded rotating shaft 19 is welded and installed on the side of the connecting shaft 18 away from the first motor 17. The first motor 17 drives the threaded rotating shaft 19 to rotate through the connecting shaft 18.

[0031] In a preferred embodiment, the limiting component 5 includes a slider 20, a groove 21, and a limiting plate 22. The groove 21 is placed on the side of the slider 20, and the limiting plate 22 is installed on the top of the slider 20. The threaded component 4 and the slider 20 are connected by threads, and the two sides of the slider 20 are limited by the groove 21. The slider 20 and the groove 21 are slidably connected. Therefore, when the threaded component 4 rotates, the slider 20, which is connected to the threaded component 4 by threads, can slide horizontally in the groove 21 because its two sides are limited by the groove 21 and the threaded component 4 gives the slider 20 a forward thrust by rotating. The limiting plate 22 can limit the position of the object on the slider 20, so that the object will not tilt and fall off the slider 20 due to the inertia of the slider 20's movement.

[0032] The working process of this utility model is as follows: First, when pre-degreasing treatment is required for hot-dip galvanized structural parts, the worker first fixes the object on the limiting component 5, and then adjusts the distance between the brush mechanism 2 and the object through the displacement component 3. When the worker adjusts the height of the brush mechanism 2, the electric lifting rod 12 will drive the second connecting plate 10 to move vertically through the telescopic rod 11. The second connecting plate 10 and the first connecting plate 9 are fixed by bolts. When the second connecting plate 10 moves vertically, the first connecting plate 9 will also move vertically, and the brush mechanism 2 connected to the first connecting plate 9 through the bearing will also move vertically. Then, the position of the slider 20 is moved by the threaded component 4 of the sliding mechanism 1, so that the object above the slider 20 also moves horizontally. When the threaded component 4 rotates, the first motor 17 drives the threaded rotating shaft 19 to rotate through the connecting shaft 18. The threaded rotating shaft 19 is connected to the slider 20 through the thread. Because its two sides are limited by the sliding groove 21, and the threaded component 4 gives the slider 20 a forward direction by rotating. The object is propelled by the thrust of the slider 20, allowing it to slide horizontally in the groove 21. The limiting plate 22 on the slider 20 can limit the position of the object, preventing it from tilting and falling off the slider 20 due to its inertia. During the horizontal movement of the object, the conveying component 6 of the brush mechanism 2 drives the cleaning brush 8 on the mounting groove 7 to clean the object on the limiting component 5. When the conveying component 6 rotates, the second motor 13 drives the roller 15 on its outer diameter surface to rotate through the first rotating shaft 14. The roller 15 drives the conveyor belt 16 to rotate on the outer diameter surface of the roller 15 through friction. When the conveyor belt 16 rotates, the mounting groove 7 fixed to its surface by bolts and the cleaning brush inside it will also move horizontally to clean the objects on the slider 20. During the cleaning process of the cleaning brush 8, the worker also needs to open the degreasing agent nozzles on both sides of the sliding mechanism 1 so that the exposed surface of the object can be evenly sprayed with degreasing agent during the movement. The above is the working principle of the pre-degreasing device for hot-dip galvanized structural parts.
