Description

Technical Field

[0001] This utility model belongs to the field of spray painting technology, and specifically relates to a spray painting device for plastic parts. Background Technology

[0002] After plastic parts are manufactured, they need to be painted. For safety reasons, to avoid inhaling paint or contact with the skin, a protective sleeve needs to be fitted on the outside of the spray gun during the painting process. However, the existing protective sleeves are relatively soft and are prone to deformation under external force, making them inconvenient to use.

[0003] For example, patent number CN218078509U discloses a plastic part painting masking device, including a fixing sleeve, which is a cylindrical structure. The lower side of the fixing sleeve is fixed to the masking cover. The masking cover is a ring structure with a small opening at the top and a large opening at the bottom. The side of the fixing sleeve is provided with a mounting hole, and a positioning structure is screwed into the mounting hole. By providing a bottom edge at the bottom of the masking cover, the deformation resistance of the bottom of the masking cover is greatly improved, reducing the deformation after being subjected to external forces. The reinforcing strips located on the side of the masking cover further improve the overall deformation resistance of the masking cover, reducing its deformation after being subjected to external forces.

[0004] When using the above-mentioned device, it is necessary to first manually cover the outside of the workpiece, then carry out the painting process. After the process is completed, the cover is then manually lifted up to remove the workpiece before the next workpiece is processed, which results in low processing efficiency. Utility Model Content

[0005] Based on the problems mentioned in the background technology above, this utility model provides a plastic parts painting device to solve the problem of low processing efficiency caused by the fact that some plastic parts painting masking devices require manual covering of the outside of the workpiece before painting, and then manual lifting of the masking cover to remove the workpiece before processing the next workpiece.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A plastic parts painting apparatus, comprising:

[0008] The cylinder has a cone-shaped top and an operating port on its periphery. Two closed doors are slidably arranged opposite each other at the operating port.

[0009] A rotating placement platform is located at the bottom of the cylinder;

[0010] A painting assembly is disposed on the peripheral sidewall of the cylinder;

[0011] A baking assembly is disposed at the top opening of the cylinder;

[0012] A shielding assembly is disposed at the top opening of the cylinder and located below the baking assembly;

[0013] A drive assembly, located on the outside of the cylinder, is used to drive the adjustment shielding assembly.

[0014] Based on the above technical solution, the present invention has made the following improvements:

[0015] Furthermore, the rotating placement platform includes a motor and a turntable. The motor is mounted at the bottom of the cylinder via a mounting bracket, and the turntable is secured to the bottom of the cylinder. The drive shaft of the motor is connected to the shaft at the center of the bottom of the turntable. The top of the turntable is provided with two top posts and two support posts. The two top posts are higher than the two support posts, and each of the two top posts has a notch on the top side near the support posts.

[0016] Furthermore, the painting assembly includes a spray head, which is disposed on the peripheral side wall of the cylinder. A connecting pipe is provided on the part of the spray head located on the outer side of the cylinder, and multiple spray pipes are provided on the side wall of the spray head located on the inner side of the cylinder.

[0017] Furthermore, the baking assembly includes an electric heating lamp, which is disposed at the top opening of the cylinder.

[0018] Furthermore, the shielding assembly includes a fixing sleeve disposed below the top opening of the cylinder. Multiple mounting rods are rotatably arranged in an array on the fixing sleeve. Each mounting rod is provided with a shield on its rod body located in the inner cavity of the fixing sleeve. The same side end of each mounting rod extends through to the outside of the cylinder.

[0019] Furthermore, the drive assembly includes a second motor, multiple synchronous pulleys, and a synchronous belt. The second motor is located outside the cylinder, and the drive shaft of the second motor is connected to the end of one of the mounting rods. Each synchronous pulley is located at the end of its corresponding mounting rod, and a synchronous belt is provided between each synchronous pulley.

[0020] Furthermore, flanges are provided on both sides of the operating port, and protrusions are provided on both sides of the top of each closed door. A stabilizing rod is provided between the two protrusions on each closed door, and each stabilizing rod is respectively locked in the corresponding flange.

[0021] The beneficial effects of this utility model are:

[0022] 1. The system combines a cylindrical body, two closed doors, a rotating platform, and a painting assembly. During use, the two closed doors are slidably stored inside the cylindrical body, allowing the workpiece to be placed on the rotating platform through the operating port and rotated. Then, the two closed doors slide out of the cylindrical body and snap onto the operating port. Finally, the painting assembly is used to paint the rotating workpiece. During the painting process, the closed doors can be slid open to achieve the desired seal, requiring minimal additional operation and improving processing efficiency.

[0023] 2. The baking component can be used to bake and dry the paint on the workpiece after the workpiece has been painted.

[0024] 3. By setting up a combination of masking components and driving components, the driving component drives the masking component to block the baking component before painting, so as to prevent the paint from spreading on the baking component during the painting process. After the painting is completed, the driving component drives the masking component to disperse from under the baking component, so that the baking component can be used to dry the paint on the workpiece.

[0032] like Figures 1-4 As shown in the figure, a plastic parts painting device includes:

[0033] The cylinder 101 has a conical top and an operating port 102 on its periphery. Two slidable closing doors 103 are provided at the operating port 102. Flanges 105 are provided on both sides of the operating port 102. Protrusions 106 are provided on both sides of the top of each closing door 103. A stabilizing rod 107 is provided between the two protrusions 106 on each closing door 103. Each stabilizing rod 107 is respectively locked in the corresponding flange 105, thereby realizing the sliding assembly of the two closing doors 103 at the operating port 102. When the closing door 103 is pushed, it can be stored inside the cylinder 101. When the closing door 103 is pulled, it can be moved out from the inside of the cylinder 101 and cover the operating port 102.

[0034] A rotating placement table is located at the bottom of the cylinder 101. The rotating placement table includes a motor 201 and a turntable 202. The motor 201 is mounted at the bottom of the cylinder 101 via a mounting bracket 104. The turntable 202 is secured to the inner bottom of the cylinder 101. The drive shaft of the motor 201 is connected to the shaft at the center of the bottom of the turntable 202. The motor 201 can drive the turntable 202 to rotate. The top of the turntable 202 is provided with two top posts 203 and two support posts 204. The two top posts 203 are higher than the two support posts 204. Each of the top posts 203 has a notch 205 on the top side near the support posts 204. In use, one side of the workpiece 3 is placed against the notch 205 of the support post 204, so that the bottom of the other end of the workpiece 3 rests on the top post 203. The workpiece 3 is then placed at an angle on the turntable 202. When the turntable 202 rotates, the angled workpiece 3 can rotate.

[0035] The painting assembly is disposed on the circumferential side wall of the cylinder 101. The painting assembly includes a spray head 401, which is disposed on the circumferential side wall of the cylinder 101. A connecting pipe is provided on the part of the spray head 401 located on the outer side of the cylinder 101. The connecting pipe can be connected to an external paint pipe to introduce paint into the spray head 401. Multiple spray pipes 402 are provided on the side wall of the spray head 401 located on the inner side of the cylinder 101. The paint introduced into the spray head 401 can be dispersed and sprayed out from each spray pipe 402 onto the rotating workpiece 3.

[0036] In use, push the two closed doors 103 to slide them into the inside of the cylinder 101. Then, insert the workpiece 3 into the cylinder 101 through the operating port 102, so that one side of the workpiece 3 rests against the notch 205 of the support column 204, and the bottom of the other end rests on the top column 203, causing the workpiece 3 to be placed at an angle on the turntable 202. Then, pull the closed doors 103 to move them out from the inside of the cylinder 101 and cover the operating port 102. When the turntable 202 rotates, the tilted workpiece 3 can be rotated. During the rotation of the turntable 202 and the workpiece 3, paint can be sprayed from each spray nozzle 402 onto the rotating workpiece 3 to achieve the painting operation. During the painting operation, the closed doors 103 can be slid closed, without much additional operation, which can improve processing efficiency.

[0037] See Figure 2 and Figure 4 The baking component is located at the top opening of the cylinder 101. The baking component includes an electric heating lamp 5. After the workpiece 3 is painted, the electric heating lamp 5 can be used to bake and dry the paint on the workpiece 3.

[0038] See Figure 1 , Figure 3 and Figure 4 A shielding assembly is located at the top opening of the cylinder 101 and below the baking assembly. The shielding assembly includes a fixing sleeve 601 located below the top opening of the cylinder 101. Multiple mounting rods 602 are rotatably arranged in an array on the fixing sleeve 601. Each mounting rod 602 has a shielding plate 603 on its rod body located within the inner cavity of the fixing sleeve 601. The same-side end of each mounting rod 602 extends to the outside of the cylinder 101. A drive assembly is located outside the cylinder 101. The drive assembly includes a second motor 701, multiple synchronous pulleys 702, and a synchronous belt 703. The second motor 701 is located outside the cylinder 101, and its drive shaft is connected to one of the mounting rods. The end of the 602 is connected, and each synchronous pulley 702 is respectively set at the end of the corresponding mounting rod 602. A synchronous belt 703 is provided between each synchronous pulley 702. The corresponding mounting rod 602 can be driven to rotate by the motor 701. After being driven by each synchronous pulley 702 and the synchronous belt 703, each mounting rod 602 can be driven to rotate synchronously. When each mounting rod 602 rotates synchronously, each cover plate 603 can be rotated. When each cover plate 603 rotates to a horizontal position, each cover plate 603 is closed and covers the electric heating lamp 5. When each cover plate 603 rotates to a vertical position, there is a gap between each cover plate 603, which allows the heat of the electric heating lamp 5 to be dissipated to the workpiece 3 through the gap.

[0039] Before painting, the corresponding mounting rod 602 is driven to rotate by starting motor 701. After being driven by each synchronous pulley 702 and synchronous belt 703, the mounting rod 602 is driven to rotate synchronously, causing each shield 603 to rotate to a horizontal position and close under the electric heating lamp 5, thereby preventing paint from spreading to the electric heating lamp 5 during painting.

[0040] After the painting is completed, the motor 701 is started to drive the corresponding mounting rod 602 to rotate. After being driven by the synchronous pulleys 702 and the synchronous belt 703, the mounting rods 602 are driven to rotate synchronously, causing the masking plates 603 to rotate to an upright position, creating gaps between the masking plates 603. At this time, the heat from the electric heating lamp 5 can be dissipated to the workpiece 3 through the gaps, thereby drying the paint on the workpiece 3.

[0041] The present invention has been described in detail above. The specific embodiments are provided only to help understand the method and core idea of ​​the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
