Description

Technical Field

[0001] This utility model relates to the field of painting equipment technology, specifically a multi-angle painting production line for workpieces. Background Technology

[0002] Spraying is a coating method that uses a spray gun or disc atomizer to disperse the material into uniform and fine droplets by pressure or centrifugal force and apply them to the surface of the object being coated. In the production and processing of workpieces, it is often necessary to spray anti-rust paint or topcoat on the surface of the workpiece to achieve the purpose of rust prevention or beautification.

[0003] A search revealed a Chinese patent publication number (CN 219597040 U) disclosing a workpiece painting device, comprising a paint spraying box. The paint spraying box contains a telescopic receiving assembly and a painting assembly. The telescopic receiving assembly includes slide rails fixedly installed on the left and right inner walls of the paint spraying box. A telescopic mounting frame, extending from the front of the paint spraying box to the outside, is slidably connected inside the slide rails. A holding mesh plate is fixedly installed on the inner wall of the telescopic mounting frame. This workpiece painting device uses a servo motor to drive a transmission rod, which, through the meshing of a first worm gear and a first worm wheel, drives a screw to rotate, causing the telescopic mounting frame to extend from the front of the paint spraying box along the slide rails. This facilitates the placement of workpieces on the surface of the holding mesh plate for painting. Since workers do not need to enter the paint spraying box, this avoids the inhalation of excessive toxic gases, thus protecting their health.

[0004] The workpiece painting device in the above-mentioned patent still has some shortcomings. In the existing workpiece processing production line, the surface painting of the workpiece is mostly done by personnel holding spray guns, which is extremely harmful. Although some spray guns do not require workers to hold them, the angle of their nozzles is difficult to adjust flexibly, making it impossible to paint multiple sides of the workpiece, which is inconvenient for users to use for painting. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a multi-angle painting production line for workpieces. It solves the problem that in existing workpiece processing production lines, the surface painting of workpieces is mostly done by hand-held spray guns, which is extremely harmful. Although some spray guns do not require hand-held operation, the angle of their nozzles is difficult to adjust flexibly, making it impossible to paint multiple sides of the workpiece and inconvenient for users.

[0006] This utility model provides the following technical solution: a multi-angle painting production line for workpieces, including a bottom support frame, a painting chamber at the top of the bottom support frame, two symmetrical feeding openings on both sides of the painting chamber, a workpiece conveying track through and fixedly inserted at the top of the bottom support frame, a multi-angle painting assembly for painting workpieces at multiple angles on the painting chamber, and an outer closing assembly on the side of the painting chamber.

[0007] The multi-angle painting assembly for the workpiece includes a bottom rotating disk located at the bottom of the paint spraying chamber. A drive motor is located at the center of the bottom end of the bottom support frame. The output shaft at the top of the drive motor extends through the bottom support frame to the bottom of the paint spraying chamber and is connected to the bottom end of the bottom rotating disk. Two lifting cylinders are symmetrically arranged on both sides of the top of the bottom rotating disk. Each lifting cylinder has a top connecting seat at its top. A rotating ball is rotatably embedded at the top of the top connecting seat. An abutting screw is threaded into the side of the top connecting seat. The end of the abutting screw abuts against the side of the rotating ball. A paint gun is fixedly connected to the top of the rotating ball. A paint gun receiving pipe is connected to the side of the paint gun.

[0008] Preferred technical solution 1: The outer closure component includes a side discharge port opened in the paint spraying chamber, a door frame is provided on the outer side of the discharge port, a door groove is opened on the inner side wall of the door frame, and a side insertion hole is opened on the side of the door frame.

[0009] Preferred technical solution 2: A closing plate is slidably inserted into the side insertion hole, and the sides of the closing plate are all inserted into the door groove and slidably.

[0010] Preferred technical solution 3: The end of the contact screw is provided with an anti-slip pad, and the end of the contact screw abuts against the side of the rotating ball.

[0011] This solution allows the user to fix the rotating ball bearings in place by rotating the screw.

[0012] Preferred technical solution four: The closing plate is slidably inserted into the door groove to close the middle of the door frame.

[0013] This solution enables the side of the closing plate to be more stably limited by the door groove when the closing plate slides in the door frame.

[0014] Preferred technical solution five: Two handles are symmetrically arranged on the side of the closing plate.

[0015] This solution makes it easier for users to pull the closing plate out of the door frame.

[0016] Compared with the prior art, this utility model provides a multi-angle painting production line for workpieces, which has the following beneficial effects:

[0017] (1) This utility model has a multi-angle painting component for workpieces installed on the paint spraying chamber. The angle of the paint gun in the multi-angle painting component can be adjusted appropriately by the worker rotating the ball bearing. The height of the paint gun can be moved up and down by the lifting cylinder. At the same time, the lifting cylinder can be driven by the drive motor to the bottom rotating plate, so that the paint gun installed on the lifting cylinder can spray paint the workpieces that are transported to the side of the paint gun via the workpiece conveying track at multiple angles. In this process, no human is required to enter the paint spraying chamber, which avoids the paint mist generated by the paint spraying from causing harm to the workers. At the same time, it can spray paint the surface of the workpiece at multiple angles, making it more flexible and convenient to use. Attached Figure Description

[0025] Please see Figure 1-4 ,

[0026] Example 1: A multi-angle painting production line for workpieces includes a bottom support frame 1, a paint spraying chamber 2 at the top of the bottom support frame 1, two symmetrical feeding openings 3 on both sides of the paint spraying chamber 2, a workpiece conveying track 4 that is fixedly inserted through the top of the bottom support frame 1, a multi-angle painting assembly 5 for painting workpieces at multiple angles on the paint spraying chamber 2, and an outer closing assembly 6 on the side of the paint spraying chamber 2.

[0027] The multi-angle painting assembly 5 includes a bottom rotating disk 501 set at the bottom of the paint spraying chamber 2. A drive motor 502 is set at the middle of the bottom end of the bottom support frame 1. The output shaft at the top of the drive motor 502 extends through the bottom support frame 1 to the bottom of the paint spraying chamber 2 and is connected to the bottom end of the bottom rotating disk 501. Two lifting cylinders 503 are symmetrically arranged on both sides of the top of the bottom rotating disk 501.

[0028] Each lifting cylinder 503 has a top connecting seat 504 at its top. A rotating ball bearing 505 is rotatably embedded in the top of the top connecting seat 504. An abutting screw 506 is threaded into the side of the top connecting seat 504. The end of the abutting screw 506 abuts against the side of the rotating ball bearing 505. A paint gun 507 is fixedly connected to the top of the rotating ball bearing 505. A paint gun receiving pipe 508 is connected to the side of the paint gun 507.

[0029] The outer closing component 6 includes a side outlet 601 opened on the side of the paint spraying chamber 2. A door frame 602 is provided on the outer side of the outlet 601. A door groove 603 is opened on the inner side wall of the door frame 602. A side insertion hole 604 is opened on the side of the door frame 602. A closing plate 605 is slidably inserted into the side insertion hole 604. The sides of the closing plate 605 are all inserted into the door groove 603 and slide.

[0030] Example 2: The difference between this example and Example 1 is that the end of the contact screw 506 is provided with an anti-slip pad, and the end of the contact screw 506 abuts against the side of the rotating ball 505.

[0031] This allows the user to fix the rotating ball bearing 505 in place by rotating the screw 506.

[0032] Example 3: The difference between this example and Example 1 is that the closing plate 605 is slidably inserted into the door groove 603 to close the middle part of the door frame 602.

[0033] This makes the side of the closing plate 605 more stable as it slides in the door frame 602, due to the limiting effect of the door groove 603.

[0034] Example 4: The difference between this example and Example 1 is that the closing plate 605 has two handles symmetrically arranged on its side.

[0035] This makes it easier for users to pull the closing plate 605 out of the door frame 602.

[0036] In this embodiment, since the surface painting of workpieces in existing workpiece processing production lines is mostly done by hand-held spray guns, which is extremely dangerous. Although some spray guns do not require hand-held operation, the angle of their nozzles is difficult to adjust flexibly, making it impossible to paint multiple sides of the workpiece and inconvenient for users to use for painting.

[0037] In summary, in practical implementation, when a user needs to spray paint the surface of a workpiece conveyed by the workpiece conveying track 4, the workpiece will be moved above the workpiece multi-angle spray painting assembly 5 under the conveying of the workpiece conveying track 4. At this time, the user can start the lifting cylinder 503 in the workpiece multi-angle spray painting assembly 5, so that the lifting cylinder 503 can push the top connecting seat 504 upward, and push the paint gun 507 set on the top of the top connecting seat 504 to the side of the workpiece. Furthermore, the spraying direction of the paint gun 507 can be reasonably adjusted by rotating the rotating ball 505. By connecting the paint material to the spray gun receiving pipe 508, multiple areas of the workpiece surface can be sprayed.

[0038] Next, the user starts the drive motor 502, which drives the bottom rotating plate 501 to rotate, which in turn drives the two lifting cylinders 503 on it to rotate. This allows the paint gun 507 on the lifting cylinders 503 to move around the workpiece, enabling multi-angle painting of the workpiece surface. During this process, no one needs to enter the paint spraying chamber 2, avoiding the harm to workers caused by paint mist. At the same time, it can paint the workpiece surface from multiple angles, making it more flexible and convenient to use.
