Description

Technical Field

[0001] The utility model relates to the technical field of spraying, in particular to a pressure tank for spraying suitable for a small batch production mode. Background Art

[0002] In the traditional spraying production industry, spraying operations are generally carried out manually or by robots. Manual spraying is when a person wears relevant protective equipment to spray the workpiece in the spray paint room, which will result in high labor costs and low production capacity. If it is robot spraying, then its main equipment will be planned in the spray paint room and the paint supply room. The paint supply equipment is mainly composed of raw material barrels, agitators, pumps, etc. in the paint supply room. Under normal circumstances, the spray paint room and the paint supply room are separated by several meters to tens of meters due to reasons such as the site. In addition, due to the large output and usage, the equipment in the paint supply room is large in volume and capacity and large in number. Due to the long distance, the paint transmission and mixing ancillary equipment such as pipelines will also reach several meters or even tens of meters, which is more suitable for some production companies with relatively large output. However, if some special materials are used, since the paint itself is extremely expensive, any waste will result in high costs, and its usage is very small, and the output of each batch is not very high. Under this premise, in the traditional model of large-scale paint transportation equipment and long-distance pipelines, the cost of purchasing equipment will increase, and spraying materials will be wasted.

[0023] 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.

[0024] As shown in the figure, the utility model discloses a pressure tank for spraying, comprising a tank body 1, a tank cover 2 is installed on the top of the tank body 1, a bracket connecting plate 3 is installed on the bottom of the tank body 1, a tank body mounting bracket 4 is installed on one side of the tank cover 2 and the bracket connecting plate 3, the tank body mounting bracket 4 is installed at a robot 5, a shaft seal 6 is installed at the middle of the upper end of the tank body 1, an air motor 7 is installed on the top of the shaft seal 6, a stirring shaft 8 is installed at the output end of the air motor 7, the end of the stirring shaft 8 is located at the bottom of the tank body 1, and a stirring paddle 9 is installed at the end of the stirring shaft 8, an air pipe 10, a pressure relief valve 11 and a pressure gauge 12 are installed on the tank cover 2, an air pressure regulating valve 13 is installed on the air pipe 10, an outlet pipe 14 is installed at the middle of the bottom of the tank body 1, an outlet valve 15 is installed at the outlet pipe 14, and an observation window 16 is provided at the front end of the tank body 1.

[0025] The tank body 1 is used to store paint. The tank body 1 is designed to discharge from the bottom, and the bottom is a dome-bottom semicircular structure, which helps to concentrate the remaining paint at the bottom discharge port to avoid waste. Since the paint needs external pressure to push the paint out from the bottom during spraying, an air pressure regulating valve 13 is installed on the tank cover 2 to connect compressed air.

[0026] The gas enters the tank 1 from the air pipe 10 at the top, filling the volume of the tank 1 except for the paint part. In order to ensure that the thrust of the paint remains constant during spraying, the pressure will continue to be given after filling. The pressure of the pressurized gas is generally between 1-6Bar, because the normal automatic spraying pressure is also between 1-6Bar, which can ensure that the paint has enough pressure when it reaches the spray gun. A pressure gauge 12 is also installed on the filling cover 2 to display the pressure, so in the working state, the tank 1 actually has a certain pressure, and the pressure is required to be stable without leakage.

[0027] Due to the particularity of the paint, if it is stored in the tank body 1 for a long time without spraying, it will often be stratified or deposited, which will affect the quality of the subsequent spraying. In order to solve this problem, the utility model installs an air motor 7 on the top of the tank body 1. The air motor is a conventional component and will not be introduced in detail here. The air motor 7 drives the stirring paddle 9 to rotate, and can stir in a non-working state to ensure the stability of the paint. Similarly, for the sealing performance of the tank body 1, the utility model installs a shaft seal 6 to ensure that the sealing performance of the output end of the air motor entering the tank body section meets the standard. At the same time, in order to be able to check the liquid level in the tank body 1 in real time, an observation window 16 is designed on the surface of the tank body 1, so that the remaining paint in the tank can be observed at any time.

[0028] Since the tank body 1 carries a certain pressure, if it is opened directly when it needs to be opened, safety accidents may easily occur due to the residual pressure. For example, the residual paint may splash onto the operator's body or even face due to the residual pressure in the tank. Therefore, a pressure relief valve 11 is designed on the tank cover 2. When the tank cover 2 needs to be opened, it is only necessary to turn off the pneumatic motor 7 and the air pressure regulating valve 13, and pull the pressure relief valve 11. After the pressure in the tank body 1 is released through the pressure relief valve 11, it can be opened safely. Similarly, in order to ensure that the length of the paint delivery pipeline can be maintained at the most reasonable length, the utility model designs a tank body mounting bracket 4, which can be installed on the mechanical arm of the robot 5, so that the distance from the outlet of the tank body 1 to the spray gun can be reasonably controlled at about 1 meter, which greatly saves the waste caused by the excessively long paint delivery pipeline.

[0029] In one embodiment of the utility model, the top of the tank body 1 is an open structure, and three groups of connecting pin mounting blocks 17 are provided on the outer side of the upper end of the tank body 1, and each group of connecting pin mounting blocks 17 is provided with two parallel connecting pin mounting blocks, and both ends of the connecting pin 18 are installed at the connecting pin mounting blocks 17, and a fixing rod 19 is fixed at the middle of the connecting pin 18, and the fixing rod 19 is provided with an external thread, and the tank cover 2 is provided with a card slot 201 corresponding to the fixing rod, and a locking ear 20 is installed on the upper end of the fixing rod 19. When the utility model is used to put paint, the tank cover 2 is first opened as a whole to facilitate the introduction of paint.

[0030] In one embodiment of the utility model, a shaft seal connecting plate 21 is installed in the middle of the top of the tank cover 2, the bottom of the shaft seal 6 is installed on the shaft seal connecting plate 21, and a lifting ring 22 is installed on the top of the tank cover 2 facing the tank body mounting bracket. The lifting ring 22 is used to lift and place the tank cover 2 as a whole.

[0031] In an embodiment of the utility model, the tank mounting bracket 4 includes a mounting vertical plate 1 41, and the upper and lower ends of the mounting vertical plate 1 41 are respectively mounted with mounting horizontal plates 42, and the other end of the mounting horizontal plate 42 is mounted with a mounting vertical plate 2 43, and the mounting vertical plate 1 41 is connected to one side of the tank cover 2 by bolts, and the mounting vertical plate 1 41 is connected to one side of the bracket connecting plate 3 by bolts. The design of the mounting vertical plate 1 43 is due to the size of the robot's mechanical arm, and the mounting vertical plate 1 41 cannot be installed on the mechanical arm as a whole, so two small-sized mounting vertical plates 2 43 are used for transfer.

[0032] In an embodiment of the present invention, four mounting holes 421 are provided on the mounting transverse plate 42, and the mounting transverse plate is connected to the robot.

[0033] In one embodiment of the utility model, the tank cover 2 is provided with a stirring shaft through hole 202, a stirring paddle avoidance hole 301 is provided in the middle of the bracket connecting plate 3, and the stirring paddle 9 is installed on the side of the stirring paddle installation shaft 23, and the stirring paddle installation shaft 23 is installed at the lower end of the stirring shaft 8. The stirring paddle 9 starts to work when needed.

The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the present utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the present utility model.
