Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and in particular to a dip-coating tank that is convenient for use with steel pipes of different sizes. Background Technology

[0002] Steel pipes, as a common metal material, are widely used in many fields such as construction, machinery, and transportation. To enhance their corrosion resistance and aesthetics, surface treatment is often required, and dip coating is an important method. Dip coating involves immersing the steel pipe in a plasticizing tank formed by molten plastic powder, allowing the plastic to adhere evenly to the surface of the steel pipe, forming a strong and attractive plastic coating. Dip coating of steel pipes plays a crucial role in industries such as civil defense engineering, bridge construction, and furniture manufacturing. As a key step in the steel pipe processing flow, the performance of the dip coating tank has a decisive influence on the dip coating effect. However, while existing dip coating tanks are designed to be relatively large and can accommodate steel pipes of various sizes, they have gradually revealed significant limitations in actual operation.

[0003] Specifically, existing dip coating tanks lack effective restraint structures, which allows steel pipes of different sizes to easily sink and roll inside the tank after being placed in it. This phenomenon not only leads to instability in the dip coating process, affecting the uniformity and adhesion of the dip coating layer, but may also cause collisions and damage between the steel pipes, thus affecting the quality of the dip-coated product.

[0004] Therefore, to address the shortcomings of existing dip coating tanks, we urgently need a dip coating tank that can accommodate steel pipes of different sizes. This type of tank should be able to easily adapt to steel pipes of varying sizes, effectively restrict the movement and rolling of the pipes within the tank, ensure the stability and uniformity of the dip coating process, improve the quality of the coated products and production efficiency, and provide strong support for the sustainable development of industries such as civil defense engineering, bridge construction, and furniture manufacturing. Utility Model Content

[0005] The purpose of this invention is to provide a dip coating tank that is convenient for use with steel pipes of different sizes. It solves the problem that existing dip coating tanks lack an effective limiting structure, which makes it easy for steel pipes of different sizes to sink and roll inside the tank after being placed in it.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A plastic coating tank that is convenient for use with steel pipes of different sizes includes a plastic coating chamber and two support blocks symmetrically arranged on both sides inside the plastic coating chamber;

[0008] A support frame is provided at the center of the bottom of the inner cavity of the dip-coating chamber, and a connecting structure is connected to both sides of the support frame. Vertical lifting components connected to the connecting structure are installed on both sides of the dip-coating chamber.

[0009] Both of the two bearing blocks have a sloping surface on one corresponding side.

[0010] Preferably, the bottom and sidewalls of the bearing block are fixedly connected to the inner wall of the dip-coating chamber, and a number of stepped grooves are linearly arranged on one side of the inclined surface along the inclined direction.

[0011] Preferably, the connecting structure includes a vertical frame and a top frame, the bottom of the vertical frame being connected to the top of the support frame, and the top of the vertical frame being connected to the bottom of the top frame.

[0012] Preferably, the distance between the two support blocks is greater than the length of the support frame, and the height of the support block is less than the height of the dip-molding chamber.

[0013] Preferably, the vertical lifting assembly includes a mounting plate bolted to the side wall of the dip coating chamber and a lifting cylinder connected to the center of the bottom of the mounting plate, wherein the output end of the lifting cylinder slides through the mounting plate and is connected to the bottom of the top frame.

[0014] Preferably, both sides of the bottom of the top frame are fixedly connected to a guide rod with one end sliding through the mounting plate, and the inside of the support frame is connected to a crossbar.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Example 1

[0026] Please see Figure 1-5 As shown, this embodiment provides a dip coating tank that is convenient for use with steel pipes of different sizes, including a dip coating chamber 1 and two support blocks 3 symmetrically arranged on both sides inside the dip coating chamber 1.

[0027] A support frame 2 is provided at the center of the bottom of the inner cavity of the dip coating chamber 1. Both sides of the support frame 2 are connected to the connecting structure. Both sides of the dip coating chamber 1 are equipped with vertical lifting components connected to the connecting structure.

[0028] Both load-bearing blocks 3 have inclined surfaces 4 on their corresponding sides.

[0029] First, the steel pipes to be dipped are placed into the dip-coating chamber 1. A support frame 2 is located at the center of the bottom of the inner cavity of the dip-coating chamber 1. The support frame 2 is designed to initially support and position the steel pipes and lower them into the dip-coating chamber 1. Connecting structures are attached to both sides of the support frame 2. These connecting structures are connected to vertical lifting components installed on both sides of the dip-coating chamber 1, allowing the support frame 2 to move up and down inside the dip-coating chamber 1, thus loading and unloading the steel pipes.

[0030] Meanwhile, symmetrical support blocks 3 are arranged on both sides inside the dip coating chamber 1, and inclined surfaces 4 are opened on the corresponding side of each support block 3. The design of these inclined surfaces 4 cleverly utilizes the principles of physics. When the steel pipe is placed into the dip coating chamber 1, regardless of its diameter, it will naturally move towards the inclined support blocks 3 on both sides due to gravity and be restricted by the inclined surfaces 4, thereby effectively preventing the steel pipe from rolling and displacing during the dip coating process.

[0031] After both ends of the steel pipe come into contact with the inclined plane 4, the support frame 2 will continue to descend to the bottom of the dip-coating chamber 1.

[0032] During the dip coating process, the plasticizing tank formed by the molten plastic powder surrounds the steel pipe. Because the steel pipe is stably restrained by the inclined surface 4 of the bearing block 3, the plastic powder can be evenly adhered to the surface of the steel pipe, forming a strong and aesthetically pleasing plastic coating. The entire dip coating process is stable and efficient, ensuring the uniformity and adhesion of the dip coating layer.

[0033] Example 2

[0034] Please see Figure 1-5 As shown in this embodiment, a dip-coating tank is designed for use with steel pipes of different sizes. The bottom and side walls of the support block 3 are fixedly connected to the inner wall of the dip-coating chamber 1. Several stepped grooves 5 are linearly arranged on one side of the inclined surface 4 along its inclination direction. Specifically, when the steel pipe is placed into the dip-coating chamber 1, its two ends will naturally lean towards the inclined surface 4 of the support block 3 due to gravity. As the support frame 2 descends, the two ends of the steel pipe will gradually enter the stepped grooves 5. The design of the stepped grooves 5 allows steel pipes of different diameters to find suitable support points, further stabilizing the position of the steel pipe. The linear array design of the stepped grooves 5 enhances the limiting ability of the support block 3 on the steel pipe, ensuring that the steel pipe will not roll or shift due to external forces or its own weight during the dip-coating process, thus improving the uniformity and adhesion of the dip-coating layer.

[0035] The distance between the two support blocks 3 is greater than the length of the support frame 2, and the height of the support block 3 is less than the height of the dip coating tank 1. Specifically, this design ensures that the support frame 2 will not interfere with the support block 3 when moving up and down, while the height design of the support block 3 allows the steel pipe to be fully immersed in the plasticizing tank. This spacing and height design improves the applicability and flexibility of the dip coating tank, allowing steel pipes of different lengths to be stably supported and dip coated.

[0036] Example 3

[0037] Please see Figure 1-5 As shown in the figure, this embodiment of a dip-coating tank, which is convenient for use with steel pipes of different sizes, includes a connecting structure comprising a vertical frame 8 and a top frame 7. The bottom of the vertical frame 8 is connected to the top of the support frame 2, and the top of the vertical frame 8 is connected to the bottom of the top frame 7. Specifically, the vertical frame 8 and the top frame 7 serve as a connecting structure, connecting the support frame 2 to the vertical lifting assembly. When the lifting cylinder 9 operates, it transmits force through the top frame 7 and the vertical frame 8, driving the support frame 2 to move up and down. This connecting structure design makes the up-and-down movement of the support frame 2 more stable and reliable, improving the working efficiency and stability of the entire dip-coating tank.

[0038] The vertical lifting assembly includes a mounting plate 6 bolted to the side wall of the dip coating chamber 1 and a lifting cylinder 9 connected to the bottom center of the mounting plate 6. The output end of the lifting cylinder 9 slides through the mounting plate 6 and connects to the bottom of the top frame 7. Specifically, the lifting cylinder 9 is fixed to the side wall of the dip coating chamber 1 via the mounting plate 6, and its output end is connected to the top frame 7. When the lifting cylinder 9 operates, its output end pushes the top frame 7 to move up and down, thereby causing the support frame 2 and the steel pipe to move up and down together. The use of the lifting cylinder 9 provides a stable and controllable lifting force, making the up and down movement of the support frame 2 and the steel pipe more accurate and efficient.

[0039] Both sides of the bottom of the top frame 7 are fixedly connected to guide rods 10, one end of which slides through the mounting plate 6. A crossbar 11 is connected inside the support frame 2. Specifically, the guide rods 10 are designed to guide the vertical movement of the top frame 7, ensuring the accuracy and stability of its movement path. The crossbar 11 is used to enhance the structural strength of the support frame 2 and improve its load-bearing capacity. The use of guide rods 10 and crossbars 11 improves the structural stability and load-bearing capacity of the entire dip coating tank, making the dip coating process more reliable and safe. At the same time, the guiding role of the guide rods 10 also ensures the accuracy of the vertical movement path of the support frame 2 and the steel pipe.

[0040] This solution includes the following work process:

[0041] First, the steel pipe to be dipped is placed into the dip-coating chamber 1. A support frame 2 is located at the center of the bottom of the inner cavity of the dip-coating chamber 1. The support frame 2 is designed to initially support and position the steel pipe. After the steel pipe is placed on the support frame 2, connecting structures are connected to both sides of the support frame 2. These connecting structures specifically include a vertical frame 8 and a top frame 7. The bottom of the vertical frame 8 is connected to the top of the support frame 2, and the top of the vertical frame 8 is connected to the bottom of the top frame 7. Vertical lifting assemblies connected to the connecting structures are installed on both sides of the dip-coating chamber 1. The vertical lifting assemblies include a mounting plate 6 bolted to the side wall of the dip-coating chamber 1 and a lifting cylinder 9 connected to the center of the bottom of the mounting plate 6. The output end of the lifting cylinder 9 slides through the mounting plate 6 and connects to the bottom of the top frame 7.

[0042] Meanwhile, symmetrical support blocks 3 are arranged on both sides inside the dip coating chamber 1. The bottom and side walls of the support blocks 3 are fixedly connected to the inner wall of the dip coating chamber 1. An inclined surface 4 is opened on one side of each of the two support blocks 3. Several stepped grooves 5 are linearly arranged on one side of the inclined surface 4 along the inclined direction of the inclined surface 4. When the steel pipe is placed into the dip coating chamber 1, its two ends will naturally move towards the inclined surface 4 of the support block 3 due to gravity. As the support frame 2 descends, the lifting cylinder 9 drives the top frame 7, which in turn drives the support frame 2 to descend through the vertical frame 8. The two ends of the steel pipe will gradually enter the stepped grooves 5. The design of the stepped grooves 5 allows steel pipes of different diameters and lengths to find suitable support points, further stabilizing the position of the steel pipe.

[0043] The distance between the two support blocks 3 is greater than the length of the support frame 2, and the height of the support block 3 is less than the height of the plasticizing tank 1. This design ensures that the support frame 2 will not interfere with the support block 3 when it moves up and down. At the same time, the height design of the support block 3 allows the steel pipe to be fully immersed in the plasticizing tank.

[0044] During the dip coating process, the plasticized tank formed by the molten plastic powder surrounds the steel pipe. Because the steel pipe is stably restrained by the inclined surface 4 and stepped groove 5 of the bearing block 3, the plastic powder can adhere evenly to the surface of the steel pipe, forming a strong and aesthetically pleasing plastic coating. The entire dip coating process is stable and efficient.

[0045] In addition, guide rods 10 with one end sliding through the mounting plate 6 are fixedly connected to both sides of the bottom of the top frame 7. The guide rods 10 are designed to guide the up and down movement of the top frame 7, ensuring the accuracy and stability of its movement path. A crossbar 11 is connected inside the support frame 2. The crossbar 11 is used to enhance the structural strength of the support frame 2 and improve its load-bearing capacity.
