Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spray painting, in particular to an automatic spray painting line for plastic parts. Background Art
[0002] Spray painting is a processing method that uses a spray gun to atomize paint and apply it to the surface of an object. There are many types of spray painting, including compressed air spray painting, high-pressure airless spray painting, and electrostatic spray painting. Spray painting uses flammable paints containing a large amount of solvents. Under conditions that require quick drying, the solvent vapor evaporates into the air and is likely to form an explosive mixture. In particular, electrostatic spray painting is carried out at a high voltage of more than 60 kV. If the distance between the spray nozzle and the workpiece to be painted is within 250 mm, spark discharge is very likely to occur, which will ignite flammable vapors.
[0003] During the use of the existing automatic spray painting line for plastic parts, due to the poor sealing effect of the spray painting line, gas containing flying paint will overflow from the spray painting line and cause surrounding air pollution. If the workers around the spray painting line inhale the gas containing flying paint, it will cause damage to their bodies and easily cause diseases. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] Embodiment 1:
[0020] like Figure 1-3 As shown, a plastic parts automatic painting line includes a sealing box 1, a rotating table 2, a lifting plate 3 and a painting assembly 4. The above structure is directly quoted from the prior art and will not be described in detail here.
[0021] A sealing plate 5 is slidably connected to the inner wall of the sealing box 1, and the sealing plate 5 can seal and protect the sealing box 1. A movable block 6 is fixedly connected to one side of the sealing plate 5. The movable block 6 is arranged in an L shape. A through groove 7 is opened on one side of the movable block 6. A card slot 8 is connected to one side of the through groove 7. The number of the card slots 8 is set to two and the two card slots 8 are arranged in a mirror-symmetrical manner with the through groove 7 as the center. The movable block 6 and the sealing box 1 are fixed by a limiter.
[0022] The limiting member includes a support block 9, which is fixedly installed on one side of the sealing box 1. A clamping plate 10 is fixedly connected to the top of the support block 9. A through hole identical to the clamping slot 8 is opened on one side of the clamping plate 10. A movable column 11 is slidably connected to the inner wall of the clamping plate 10, and the movable column 11 is adapted to the through slot 7.
[0023] Embodiment 2:
[0024] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, one end of the movable column 11 is fixedly connected to a circular block 12, one side of the circular block 12 is fixedly connected to a spring 13, the spring 13 is fixedly connected to one side of the support block 9, and the spring 13 is sleeved on the outer wall of the movable column 11.
[0025] Embodiment three:
[0026] The technical solution is basically the same as that of the first embodiment, except that Figure 1 and Figure 2 As shown, the inner wall of the sealing box 1 is slidably connected with a sealing strip 14, the number of the sealing strips 14 is set to two and the two sealing strips 14 are abutted against each other in a mirror-symmetrical arrangement, an arc groove 15 is opened on one side of the sealing strip 14, and when the two sealing strips 14 abut against each other, the two arc grooves 15 will be combined into a circular hole, and the pipe in the paint spraying assembly 4 will be inserted into the circular hole.
[0027] The outer wall of the sealing strip 14 is fixedly connected with a second spring 16 , and the second spring 16 is fixedly connected to the inner wall of the sealing box 1 . The second spring 16 pushes the two sealing strips 14 to abut against each other.
[0028] In summary, when the working line provided in the present embodiment is in operation, the staff first delivers the plastic parts to the rotating table 2 of the sealing box 1 through the manipulator or the transport component, and then the staff grabs the circular block 12 to move the movable column 11, and then the staff can move the sealing plate 5 through the movable block 6. After the sealing plate 5 moves upward, the card plate on the support block 9 will be inserted into the through groove 7 on the movable block 6, and the movable column 11 will be on the same horizontal line with the card slot 8. At this time, the staff can release the circular block 12, and the spring 13 will push the movable column 11 to insert into the inside of the card slot 8, thereby fixing the sealing plate 5 on one side of the sealing box 1, so that the sealing box 1 is sealed before painting, so that the gas containing flying paint during the painting process will not pollute the surrounding air;
[0029] During the process of spraying paint on the plastic parts, the lifting plate 3 will drive the spray head in the spray assembly 4 to move up and down so as to spray paint on the entire plastic parts. However, the up and down movement of the spray head will drag the spray pipe to move, and the spray pipe will move in the arc groove 15. Since the number of sealing strips 14 is set to two, no matter whether the spray pipe moves up or down, the spring 16 will push the sealing strip 14 to make the arc groove 15 firmly abut against the spray pipe, thereby improving the sealing performance of the device and reducing the pollution of the surrounding air by the flying paint during the movement of the spray pipe.
[0030] When the painting work is completed, the staff only needs to grab the circular block 12 to move the movable column 11 from the slot 8. Due to gravity, the sealing plate 5 will drive the movable block 6 to move downward, and the movable block 6 will be separated from the supporting block 9. The sealed box 1 will be opened, and the staff can take the painted plastic parts out of the sealed box 1 through a manipulator or a transport component.
[0031] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
