Description

Technical Field

[0001] This utility model relates to the field of paint removal technology for hooks, and in particular to a blade wheel for cleaning sprayed hooks. Background Technology

[0002] When the coating production line is running, the workpiece is hung on the production line hook and moves along with the production line. During powder coating operation, the hook and the workpiece are coated with powder at the same time, and then they go to the curing chamber for curing. After curing, the plastic powder has insulating properties, and over time the conductivity of the hook decreases, affecting the coating effect.

[0003] Currently, methods for removing solidified plastic powder include chemical soaking, incineration, physical extrusion, and physical grinding. Existing technology includes patent 1: CN114151800A, an environmentally friendly incineration device and method for powder-coated hooks, used in the field of hook powder coating technology. This equipment uses incineration to remove solidified plastic powder, completing the cleaning of the powder-coated hooks. Existing technology also includes patent 2: CN212120548U, a paint stripping machine for spray-coated hooks, used in the field of hook paint stripping technology. This equipment uses chain-driven upper and lower extrusion rollers, which extrude the paint layer from the spray-coated hooks to clean them. However, the two sets of manganese steel chrome-plated rollers are prone to slippage when in contact with the spray-coated hooks, resulting in poor overall cleaning effect. In physical grinding, some existing technologies use steel wire rollers (steel wire wheels) as consumables. These steel wire rollers (steel wire wheels) have a short lifespan, shed steel wire, and require frequent replacement. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a blade wheel for cleaning spray hooks, which addresses the above-mentioned technical deficiencies. Multiple sets of blades are set in the shaft cylinder. The oscillation of the blades around the shaft rod changes with the shape of the part. When the shaft cylinder rotates, the blades knock off the residual paint when they come into contact with the spray hook to be cleaned. This solves the problem of frequent replacement of consumables and short service life in existing physical grinding.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a blade wheel for cleaning spray hooks, including a shaft cylinder, flanges at both ends of the shaft cylinder, multiple shafts passing through the two sets of flanges, the multiple sets of shafts being distributed in a ring around the shaft cylinder, and multiple sets of blades being sleeved in each shaft.

[0006] To further optimize this technical solution, a keyway is provided on the inner wall of the shaft cylinder.

[0007] To further optimize this technical solution, the blade includes a handle portion and a cutting edge portion, with a through hole in the handle portion and a shaft passing through the through hole.

[0008] To further optimize this technical solution, the two sides of the cutting edge are respectively provided with inwardly converging bevels, and the cutting edge extends outward radially from the flange.

[0009] To further optimize this technical solution, a non-rigid layer is fitted on the outer wall of the shaft cylinder, and an arc-shaped part is provided at the end of the tool holder away from the cutting edge. The arc-shaped part is concentrically set with the through hole, and the arc-shaped part contacts and fits with the non-rigid layer.

[0010] Compared with the prior art, this utility model has the following advantages: 1. Multiple sets of blades are set in the shaft cylinder. The swing of the blades around the shaft rod will change with the shape of the part. When the shaft cylinder rotates, the blades knock off the residual paint when they come into contact with the spray hook to be cleaned. It has the advantages of long service life and reliable operation; 2. The swing of the blades around the shaft rod will change with the shape of the part. That is to say, it is attached to the part and changes with the shape, which has the characteristics of strong adaptability; 3. The non-rigid layer forms radial compression on the arc part, which can suppress the vibration caused by the blades knocking on the spray hook, thereby reducing noise. At the same time, it eliminates the gap between the blade holder and the shaft cylinder, preventing foreign objects in the environment from getting stuck in the gap and causing abnormal operation of the blade wheel.

[0016] 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 specific embodiments. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0017] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" used in this application to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings. They are used solely for the convenience of describing this disclosure and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example 1

[0018] Combination Figures 1 to 3 As shown, a blade wheel for cleaning spray hooks includes a shaft cylinder 1. The inner wall of the shaft cylinder 1 is provided with a keyway 10, which is used to drive a rotating power shaft. Both ends of the shaft cylinder 1 are provided with coaxially arranged flanges 2, which are fixedly positioned relative to the shaft cylinder 1. Multiple flange holes are evenly distributed inside the flanges 2. Multiple shafts 3 are inserted between the flange holes of two sets of flanges 2, and are arranged in a ring around the shaft cylinder 1. Multiple blades 4 are fitted into each shaft 3, and the blades 4 are rotatably connected to the corresponding shaft 3.

[0019] Combination Figure 2 As shown, the blade 4 includes a handle portion 40 and a cutting edge portion 41. The handle portion 40 has a through hole 401, and the shaft 3 passes through the through hole 401. The cutting edge portion 41 has inwardly converging bevels on both sides, and the cutting edge portion 41 extends radially outward from the flange 2.

[0020] When using, combine Figures 1 to 3 As shown, the rotation of the shaft cylinder 1 and the flange 2 causes the blade 4 to extend its cutting edge 41 outward from the radial side of the flange 2 under the action of centrifugal force. When the blade 4 contacts the spray hook to be cleaned, it achieves the purpose of knocking off the residual paint. The swing of the blade 4 around the shaft 3 will change with the shape of the part, that is, it is attached to the part and changes with the shape. The hook can be quickly cleaned by the knocking of the cutting edge 41 of multiple sets of blades 4. It has a long service life and is easy to maintain. Example 2

[0021] A blade wheel for cleaning spray hooks, combined with Figure 4As shown, unlike Embodiment 1, the outer wall of the shaft cylinder 1 is fitted with a non-rigid layer 5, which can be made of rubber. The end of the handle portion 40 away from the cutting edge portion 41 is provided with an arc portion 42, which is concentrically arranged with the through hole 401 and contacts and engages with the non-rigid layer 5. In use, the non-rigid layer 5 forms radial compression on the arc portion 42, which can suppress the vibration caused by the blade 4 striking the spray hook, thereby reducing noise. At the same time, it eliminates the gap between one side of the handle portion 40 and the shaft cylinder 1, preventing foreign objects in the environment from getting stuck in the gap and causing abnormal operation of the blade wheel.

[0022] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
