Description

Technical Field

[0001] This utility model relates to the technical field of cleaning components for dip coating machines, specifically a cleaning brush head for dip coating machines. Background Technology

[0002] A dip coating machine is a processing device that uses electric heating to bring the workpiece to a certain temperature, then immerses it in a dip coating solution. Afterward, it is removed and baked in another oven to allow the dip coating solution to solidify on the workpiece before it is cooled. The dip coating solution in the machine needs frequent replacement. Because the solution solidifies on the inner wall of the machine, industrial cleaning brushes are needed to polish and clean the inner wall during solution replacement. However, existing industrial cleaning brushes are not specifically designed for dip coating machines; their bristles are not uniform or dense enough, making them prone to deformation during use, resulting in low cleaning efficiency. Furthermore, the connection between the existing industrial cleaning brushes and the rotating shaft is not strong enough, hindering efficient polishing and cleaning of the dip coating machine. Utility Model Content

[0003] This invention provides a cleaning brush head for a dip coating machine, which can solve the problems of insufficient connection strength and uneven and dense bristle clusters in existing brush heads.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cleaning brush head for a dip coating machine, comprising mounting bases symmetrically arranged axially and a connecting shaft passing between the two mounting bases. A fixing ring is clamped between the radial edges of the two mounting bases. At least two brush units are arranged axially on the radially outer side of the fixing ring. The brush clusters on the brush units extend radially outward evenly. At least two brush units have radially outward extending clamping plates on their axial upper and lower sides. The two clamping plates clamp the brush clusters on the brush units. A firm mounting connection is formed by the two mounting bases and the fixing ring, which can be firmly connected to the rotating shaft. By setting the fixing ring, brush units, and clamping plates, the brush clusters can be clamped, thus improving the grinding and cleaning efficiency.

[0005] Preferably, the connecting shaft is provided with a ring of mounting steps, and the mounting base clamps and fixes the mounting steps. Clamping the mounting steps with the mounting base can simplify the assembly structure.

[0006] Preferably, the mounting base includes a clamping mounting portion in the middle, a stepped portion on the circumferential edge, and a transition reinforcement portion for connecting the clamping mounting portion and the stepped portion. The transition reinforcement portion includes an axial sidewall connected to the stepped portion and a conical surface connected to the clamping mounting portion. An acute angle is formed between the axial sidewall and the conical surface. The fixing ring abuts against the axial sidewall. The step portion can clamp and fix the fixing ring. The transition reinforcement portion can significantly enhance the strength of the mounting base and prevent deformation during high-speed rotation. The step portion can also provide abutment for the fixing ring and radially limit the fixing ring.

[0007] Preferably, the clamp is provided with a number of protrusions that protrude into the brush clusters evenly around the circumference edge. The protrusions can be embedded into the brush clusters, which can improve the uniformity of the brush clusters and prevent the brush clusters from shifting too much, thus improving the polishing effect.

[0008] Preferably, the protrusion is formed by flanging an X-shaped through-slot through the clamping plate, which is simple to form and can complete the formation of the protrusion at the same time as processing the X-shaped through-slot.

[0009] Preferably, the brush unit includes a U-shaped clamp and a limiting ring disposed within the clamp. The brush cluster passes through the space between the limiting ring and the clamp, which can improve the installation firmness of the brush cluster.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] With a simple structure, it forms a sturdy mounting connection through two mounting bases and a retaining ring, which can be firmly connected to the rotating shaft. By setting the retaining ring, brush unit and clamping plate, the brush cluster can be clamped, which can improve the grinding and cleaning efficiency. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] like Figure 1-2 As shown, in order to solve the problems of insufficient connection strength and uneven and tight brush clusters in existing brush heads, this utility model provides a cleaning brush head for a dip coating machine, including mounting bases 2 arranged symmetrically along the axis and a connecting shaft 1 passing between the two mounting bases 2. A fixing ring 6 is clamped between the radial edges of the two mounting bases 2. At least two brush units 3 are arranged axially on the radially outer side of the fixing ring 6. The brush clusters on the brush units 3 extend radially outward evenly. At least two brush units 3 are provided with radially outward extending clamping plates 7 on the upper and lower sides along the axis. The two clamping plates 7 clamp the brush clusters on the brush units 3. A strong mounting connection is formed by the two mounting bases 2 and the fixing ring 6, which can be firmly connected to the shaft. By setting the fixing ring 6, brush units 3 and clamping plates 7, the brush clusters can be clamped tightly, which can improve the grinding and cleaning efficiency.

[0017] Specifically, the mounting base 2 is made of sheet metal in one piece. The fixing ring 6 and the mounting base 2 can be interference-fitted, such as riveting or interference snap-fit, to ensure the connection strength between the two. During installation, the mounting base 2 can be connected to the connecting shaft 1 first, and then the fixing ring 6 can be installed. Alternatively, the fixing ring 6 can be assembled with the brush unit 3 and the clamping plate 7 first, and then installed with the mounting base 2. The brush unit 3 is a separate unit. Multiple brush units 3 are stacked axially, and the brush clusters are superimposed and pressed together to form a cleaning component with a relatively high density. The brush clusters can be made of plastic or metal wire.

[0018] In this embodiment, a ring of mounting steps 11 is provided on the connecting shaft 1, and the mounting base 2 clamps and fixes the mounting steps 11. The mounting base 2 can simplify the assembly structure by clamping the mounting steps 11.

[0019] In this embodiment, the mounting base 2 includes a clamping mounting portion 25 located in the middle, a stepped portion 24 disposed on the circumferential edge, and a transition reinforcing portion 21 for connecting the clamping mounting portion 25 and the stepped portion 24. The transition reinforcing portion 21 includes an axial sidewall 23 connected to the stepped portion 24 and a conical surface 22 connected to the clamping mounting portion 25. An acute angle is formed between the axial sidewall 23 and the conical surface 22. The fixing ring 6 abuts against the axial sidewall 23. The fixing ring 6 can be clamped and fixed by the stepped portion 24. The transition reinforcing portion 21 can greatly enhance the strength of the mounting base 2 and is not easily deformed when rotating at high speed. The stepped portion 24 can also provide abutment for the fixing ring 6 and radially limit the fixing ring 6.

[0020] In this embodiment, as Figure 1-2 As shown, the clamping plate 7 has several protrusions 8 evenly arranged around its circumference, protruding towards the brush cluster. These protrusions 8 can be embedded into the brush cluster, improving its uniformity and preventing significant misalignment, thus enhancing the polishing effect. The protrusions 8 are formed by flanging an X-shaped through-slot penetrating the clamping plate 7, simplifying the forming process and allowing the protrusions 8 to be formed simultaneously with the X-shaped through-slot.

[0021] In this embodiment, the brush unit 3 includes a U-shaped clamp 4 and a limiting ring 5 disposed within the clamp 4. The brush cluster passes through the space between the limiting ring 5 and the clamp 4, which can improve the installation firmness of the brush cluster.

[0022] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0023] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
