Description

An efficient furniture automatic spraying device

technical field

The invention relates to an efficient automatic paint spraying device for furniture, which belongs to the field of furniture spraying devices.

Background technique

In the furniture manufacturing industry, painting furniture is a necessary process step. Painting can be done as a whole or in steps. The overall spray painting is to use the spray cavity to spray the assembled furniture at one time. The advantage of this is that the painting is simple and the painting efficiency is high, but there are spray dead corners, and the paint cannot be sprayed to these dead corners. Another method of painting is to paint each part before assembling, and then assemble after painting. This painting method is simple, easy to operate, and there is no dead angle for painting. This spraying method is also commonly used now.

Since the paint contains many substances that are harmful to the human body, long-term exposure to these paints will cause great harm to the body. Moreover, when workers spray paint with a spray gun, due to their lack of personal experience, the quality of the spray paint varies. The quality that comes out depends entirely on the operation of the workers. With the current increase in labor costs, the use of artificial painting is no longer suitable for the development of enterprises. Therefore, it is very necessary to develop equipment that can automatically complete the painting operation.

Some furniture panels have different colors on the side and top surface, which require two painting operations, which are more complicated.

Detailed ways

The following description serves to disclose the invention to enable those skilled in the art to practice the invention. The preferred embodiments described below are given by way of example only, and other obvious modifications will occur to those skilled in the art.

As shown in Figures 1 to 5, in one embodiment of the present invention, an efficient automatic paint spraying device for furniture includes a conveying frame 1, a storage board 2, a baffle mechanism and a paint spraying mechanism.

The conveying rack 1 drives the storage board 2 to move through the chain drive 3 . The middle position of the conveying rack 1 is provided with a track groove 4 for rotating the storage board 2 , and a rotating stopper 5 is arranged at the entrance of the track groove 4 . The bottom surface of the storage board 2 is distributed with four bumps in a square shape, and the two bumps located on the side with the chamfer 6 are the front wheels 7, the front wheels 7 are cylinders, and the diameter is the width of the track groove 4; The two bumps on the side are the rear wheel 8, the rear wheel 8 is a boss type, the section connecting the storage board 2 is a cylinder with a diameter smaller than the width of the rotating block 5, and the other section is a cylinder with a diameter equal to the width of the track groove 4.

The baffle mechanism is composed of baffle 9 , lateral adjustment rod 10 , height adjustment rod 11 , gear set 12 , motor 13 and gas rod 14 . The baffle plate 9 is fixed between the two lateral adjustment rods 10 and forms an included angle of 45° with the lateral adjustment rods 10 . A first laser sensor 15 is provided at the end of the lateral adjustment rod 10 to which the baffle 9 is fixed. The lateral adjustment rod 10 is slidably connected to one end of the height adjustment rod 11 , and the rack section of the height adjustment rod 11 is half of the tooth surface 21 and half of the flat surface 20 . When the height adjusting rod 11 is in the initial position, the tooth surface 21 of the lateral adjusting rod 10 is at the same height as the side of the storage board 2 on which the wooden board 19 is placed. The gear set 12 is composed of two gears, which can be matched with the two lateral adjustment rods 10 or with the two height adjustment rods 11 at the same time. One end of the air rod 14 is fixed to the motor 13 , and the position of the gear set 12 is adjusted by the expansion and contraction of the air rod 14 . The baffle mechanism is symmetrically located on both sides of the conveying frame 1 .

The paint spraying mechanism is composed of a paint spraying rack and a second laser sensor 16 . Two paint spraying racks are fixed on the transfer frame 1, including a first paint spraying frame 17 and a second paint spraying frame 18. The first paint spraying frame 17 and the second paint spraying frame 18 are evenly distributed on the side of the conveying frame 1. A plurality of paint spraying ports are evenly distributed on both sides of the first paint spraying rack 17 and the second paint spraying rack 18 perpendicular to the ground. A second laser sensor 16 is installed on both sides of the first paint spraying rack 17 and the second paint spraying rack 18 parallel to the direction of the chain drive 3 to control the switches of the first paint spraying rack 17 and the second paint spraying rack 18 .

When placing the pallet 2 at the starting position of the conveyor 1, make the side of the pallet 2 with the chamfer 6 in the forward direction. The wooden board 19 is placed on the storage board 2. When the object storage board 2 moves linearly on the conveying frame 1 and passes through the baffle mechanism, the first laser sensor 15 at one end of the lateral adjustment rod 10 detects the wooden board 19, and the motor 13 starts to rotate, making the gear set 12 Drive the lateral adjustment rod 10 to move towards the wooden board 19, the lateral adjustment rods 10 on both sides of the wooden board 19 move at the same time, adjust the wooden board 19 to the center position and the sides are parallel to the paint spraying port. When the lateral adjustment rods 10 on both sides contact the wooden board 19 at the same time, the air rod 14 moves to drive the gear set 12 to disengage from the lateral adjustment rod 10 and cooperate with the height adjustment rod 11 . The gear set 12 drives the height adjustment rod 11 to move upward. When the first laser sensor 15 at one end of the lateral adjustment rod 10 cannot detect the wooden board 19, the motor 13 stops rotating. Junction. The width and height of the wooden board 19 can be known by the distance moved by the lateral adjustment rod 10 and the height adjustment rod 11. According to the size of the wooden board 19 that can be obtained by calculation, the number of spraying ports when the paint spraying rack is working is controlled, and the number of spraying ports is automatically controlled. Save on paint.

The storage board 2 continues to move forward in a straight line. When the second laser sensor 16 on the side of the paint spraying rack close to the storage board 2 detects the wooden board 19, the paint spraying rack starts to spray paint. When the second laser sensor 16 on the other side detects the wooden board 19 When it has passed, the painting is stopped and the shutter mechanism returns to the original position.

At the beginning, the storage board 2 moves in a straight line, and the two front wheels 7 are located in the forward direction. When one front wheel 7 contacts the rotating block 5, since the diameter of the front wheel 7 is larger than the width of the rotating block 5, the front wheel 7 will move along the rotating block 5. As the rotating block 5 moves to the track groove 4, the rear wheel 8 on the same side as the front wheel 7 is used as the driving force, and the rear wheel 8 always moves in a straight line, so that the storage board 2 rotates along the track groove 4 for nine times. ten degrees. At this time, the two rear wheels 8 are located on the chain on the side where the rotating block 5 is provided, and the two front wheels 7 are located on the other chain.

When moving to the second paint spraying rack 18, the same work flow as the first paint spraying rack 17 is performed to end the painting work.

The advantages of this embodiment are:

1. By setting the baffle plate 9, the side and top surface of the wooden board 19 will not interfere with each other when painting, and different colors of paint can be sprayed;

2. The furniture can be rotated 90 degrees for secondary painting to make the painting effect more uniform;

3. Laser sensors are installed on both sides of the spraying rack, and there is a pre-painting action to prevent uneven painting due to slow painting;

4. Automatically control the number of spray nozzles to save paint;

5. Automatically adjust the position of the wooden board 19 to make the painting effect more uniform;

6. The painting process is fully mechanically operated to avoid the damage of the paint to the human body.

The foregoing has shown and described the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above-mentioned embodiments.
