Description

Technical Field

[0001] The invention relates to the technical field of motor processing equipment, and in particular to a paint spraying device with a material recovery function for the outer surface of a motor housing. Background Art

[0002] Most existing castings are gray iron parts, which are very easy to rust in the air. In order to facilitate storage and long-distance transportation, the castings will be painted before leaving the factory to prevent surface corrosion. Generally, after painting, they are directly stacked on the ground. The paint on the surface of the castings will sag, and part of the paint will flow directly on the ground, causing the stacking site to be full of paint. After the paint solidifies, it adheres to the ground and is difficult to clean, which also causes waste of paint. For convenience, some companies directly spread a layer of plastic film on the ground. After the paint on the casting solidifies, the casting is moved away and the plastic film is removed, so that there will be no paint on the ground. However, this method will cause waste of plastic film and increase production costs. The paint that flows onto the plastic film cannot be recycled, resulting in waste of paint;

[0003] At present, the existing technology solves the problem that waste paint cannot be effectively processed by adding recovery boxes and recovery plates to collect excess paint from the upper processed parts. However, the paint of the processed parts cannot be completely collected, and this collection method has a low collection rate and cannot effectively recycle more excess paint.

[0004] Therefore, it is necessary to provide a paint spraying device with a material recovery function for the outer surface of a motor housing to solve the above technical problems. Summary of the invention

[0005] The technical problem solved by the present invention is to provide a paint spraying device with a material recovery function for the outer surface of a motor housing, which can effectively solve the problem that the existing device has a low collection rate and cannot effectively and reasonably recover more residual paint.

[0006] In order to solve the above technical problems, the present invention provides a paint spraying device with a material recovery function for the outer surface of a motor housing, comprising: a support frame, a paint spraying box, a grabbing portion, a paint box, and a collecting box, wherein the paint spraying box is arranged in the middle of the support frame, and paint boxes are arranged on both sides of the paint spraying box. The spray gun of the paint box penetrates the side wall of the paint spraying box and extends into the paint spraying box. The top of the paint spraying box is open-type, and a grabbing portion is arranged in the top. The upper half of the paint spraying box is two rectangular plates arranged correspondingly at a certain distance, and the lower half is a collecting plate. The cross-sectional shape of the collecting plate is an inverted triangle, and it is arranged obliquely, with the place close to the paint box as the initial point of inclination. It extends obliquely downward to the collection box. Below the end of the collection plate away from the paint box is the collection box, which is used to collect excess paint. The belt in the grabbing part is horizontally arranged on the top of the paint spraying box. A reinforcing rib is arranged below the belt. Below the reinforcing rib is the remaining assembly of the grabbing part, which extends vertically downward. A baffle is arranged on the wall of the paint spraying box between the spray gun and the belt. There are multiple baffles, which are distributed on the inner walls of the paint spraying box on both sides. The baffles on the same side are arranged at a certain distance. The baffle is in an arc shape. Its arrangement position is on the moving path of the grabbing part, and the bottom of the baffle is on the same horizontal plane as the stop rod in the grabbing part.

[0007] The bottom of the reinforcement rib of the belt is a telescopic rod, and the bottom two sides of the telescopic rod are provided with gear rods, the bottom surface of the telescopic rod is provided with a fixed rod, the bottom surface of the fixed rod is provided with a fixed plate, and the bottom surface of the fixed plate is provided with hooks. There are multiple hooks, which are evenly distributed on the bottom surface of the fixed plate.

There are multiple baffles 22, which are distributed on the inner wall surfaces of both sides of the paint spraying box 2. The baffles 22 on the same side are arranged at a certain distance. The baffle 22 is in a semicircular shape, and its setting position is on the moving path of the grabbing part 3, and the bottom of the baffle 22 is on the same horizontal plane as the stop rod 33 in the grabbing part 3;

[0031] like Figure 4 , Figure 6 As shown, the bottom of the reinforcement rib 311 of the belt 31 is a telescopic rod 32, and the bottom two sides of the telescopic rod 32 are provided with gear bars 33, the bottom surface of the telescopic rod 32 is provided with a fixing rod 34, the bottom surface of the fixing rod 34 is provided with a fixing plate 35, and the bottom surface of the fixing plate 35 is provided with a hook 36. There are multiple hooks 36, which are evenly distributed on the bottom surface of the fixing plate 35. The hooks 36 are used to fix the workpiece and move the workpiece.

[0032] like Figure 2 As shown, preferably, in one embodiment, the collection box 5 is connected to the collection plate 21 through the collection port 51 at the top thereof, and the purpose is to collect by opening the collection port 51 to reduce the solidification of the paint in the collection box 5 caused by contact with the air.

[0033] like Figure 4 As shown, preferably, in one embodiment, the spray guns 41 are provided with at least two rows, the purpose of which is to prevent insufficient paint on the workpiece due to a small spraying surface.

[0034] Preferably, in one embodiment, the belt 31 is an internally toothed belt;

[0035] Preferably, in one embodiment, the length of the reinforcing rib 311 is greater than half the length of the belt 31;

[0036] The purpose of the above two embodiments is to prevent the belt 31 from loosening after a long period of use, causing the workpiece to shake left and right, and to avoid the problem of insufficient coverage during painting.

[0037] Preferably, in one embodiment, the extension end of the lever 33 exceeds half the length of the baffle 22, so as to prevent the problem that the workpiece cannot be effectively lifted due to insufficient contact between the lever 33 and the baffle 22;

[0038] Preferably, in one embodiment, the distance between the shift rod 33 and the fixing plate 35 is greater than the height of the baffle 22;

[0042] Preferably, in one embodiment, the surface of the collecting plate 21 in contact with the paint is a smooth surface;

[0043] Preferably, in one embodiment, the collecting plate 21 has an inclination angle of 45 degrees;

[0044] The purpose of the above two embodiments is to make the collection and flow of residual paint smoother.

[0045] The working principle of a paint spraying device with material recovery function for the outer surface of a motor housing provided by the present invention is as follows:

[0046] During operation, the workpiece is hung on the hook 36 and moved along with the belt 31. After being sprayed with paint by the spray gun 41, it moves toward the collection box 5. Just after the paint is sprayed, the gear rod 33 contacts the baffle 22 and is lifted along the curved surface of the baffle 22. Since the gear rod 33 is connected to the telescopic rod 32, and the telescopic rod 32 is extended due to the weight of the workpiece, the telescopic rod 32 is retracted upward and falls after the gear rod 33 passes the highest point of the baffle 22. Due to the height difference of the telescopic rod, the fall generates vibration and is transmitted to the workpiece, causing the workpiece to vibrate as well. After multiple treatments, the remaining paint on the workpiece falls onto the collection plate 21 and flows into the collection box 5 along the collection plate 21.

[0047] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
