Description

Technical Field

[0001] The invention relates to the technical field of spraying devices, and in particular to a quick disassembly and assembly component for a spray gun arm and a spraying device. Background Art

[0002] The current automatic reciprocating spraying device (or sprayer) uses a fixed connection between the spray gun arm and the reciprocating bracket, that is, the spray gun arm and the spray gun bracket are fixed with traditional bolts. In addition, due to the high pressure in the oil pipe connected from the paint pump to the spray gun during the entire painting process, the threads must be sealed, so the thread processing requires high precision. When the thread is connected, in order to prevent leakage between the oil pipe and the oil distributor, sealant must be applied between the threads. Based on the above design, when a component of the spraying device fails, disassembly and maintenance become extremely difficult.

[0003] In addition, due to the production process requirements of different products, when switching spray guns and paints, the traditional design is fixed and the steps of replacing the gun arm are very cumbersome and require professional operation. Since it is impossible to quickly switch to the appropriate spray gun (or paint), production efficiency is affected, and the production time and cost of each unit product are increased.

[0004] It can be seen that how to make the disassembly and assembly of the spray gun arm more convenient is a technical problem that needs to be solved urgently. Summary of the invention

[0048] The second bracket 170 is fixedly connected to the second base 130 at its lower end, and is sleeved on the outside of the first base 120 , the second base 130 and the connector 140 .

[0049] In this embodiment, on the one hand, the second bracket 170 can be used to protect the first base 120, the second base 130 and the connecting head 140, which is beneficial to reduce the impact of the external environment on them, thereby helping to improve their reliability. On the other hand, the second bracket 170, the first base 120, the second base 130 and the connecting head 140 can be used as a whole, and the power device can be connected to the second bracket 170 and drive the second bracket 170 to move, so as to realize the above-mentioned overall movement.

[0050] In this embodiment, the second bracket 170 is optionally connected to a power device, wherein the power device drives the second bracket 170 to achieve the following Figure 1 The reciprocating motion in the front-to-back direction shown is helpful to meet the operation requirements of the reciprocating sprayer (or spraying device). Further optionally, the power device can be a linear motor.
