Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a workpiece spraying device for machining. Background Technology

[0002] Machinery is a general term for machines and mechanisms, which are tools and devices that can help people reduce the difficulty of work or save effort. Items such as chopsticks, brooms and tweezers can be called machinery. They are simple machines. Complex machines are composed of two or more simple machines. These more complex machines are usually called machines. From the point of view of structure and motion, there is no difference between mechanisms and machines. They are generally referred to as machinery. When processing workpieces, it is usually necessary to spray paint on their surface to form a protective layer on the surface of the workpiece to improve the service life of the workpiece.

[0003] In the existing technology, when spraying workpieces, the spraying area needs to be dried in time. However, the hot airflow can easily dry the paint in the paint spray head, which can cause the spray head to become clogged. In addition, when spraying mechanical workpieces, the operator needs to manually adjust the spraying position, which can cause the coating above to become dirty or be wiped. Utility Model Content

The feeding pipe is fixedly installed on the top of the paint storage tank, the sealing piston is located inside the feeding pipe, the pump is fixedly installed on the front of the paint storage tank, and the suction end of the pump is connected to the paint storage tank. One end of the transmission pipe is fixedly installed on the output end of the pump, the spray head is fixedly installed on the top of the turntable, the other end of the transmission pipe is fixedly installed on the input end of the spray head, and the battery is fixedly installed on the top of the sealed tank.

[0011] Preferably, the mechanical workpiece drying assembly further includes a hot air blower, a connecting pipe, and an air outlet. The hot air blower and the air outlet are both fixedly installed at the bottom of the turntable. One end of the connecting pipe is fixedly installed at the output end of the hot air blower, and the other end of the connecting pipe is fixedly installed at the input end of the air outlet. The hot air blower and the pump are electrically connected to the battery.

[0012] By adopting the above technical solution, the hot air blower can discharge hot air after starting and allow the coated workpieces to be dried without the need for workers to transfer the workpieces, thus improving work efficiency.

[0013] Preferably, the discharge trough is triangular in shape, and the paint scraper is made of high-temperature resistant steel.

[0018] By adopting the above technical solution, the placement slot facilitates the placement of workpieces, and the workpiece clamping plate is moved by the second electric telescopic rod to clamp the workpiece.

[0020] 1. This utility model, through its specially designed mechanical workpiece spraying adjustment component and mechanical workpiece drying component, features a hot air blower, air outlet, and spray head all mounted on a turntable, rotating synchronously with the second drive shaft. This ensures that the hot air and the spraying area are staggered: during spraying, the spray head is aligned with the workpiece, and during drying, the air outlet is turned towards the workpiece, preventing the hot airflow from directly contacting the paint inside the spray head and preventing the paint from drying and clogging the spray head. This solves the problem of mutual interference between drying and spraying in traditional equipment, ensuring a continuous and stable spraying process. The mechanical workpiece spraying adjustment component is driven by a first motor to drive the first drive shaft, causing the workpiece clamping plate and the workpiece to rotate. The clamping angle is adjusted in conjunction with a second electric telescopic rod, achieving automatic flipping of all sides of the workpiece. Simultaneously, the turntable drives the spray head to rotate, expanding the spraying range. No manual adjustment is required, avoiding coating contamination or wiping damage caused by hand contact, ensuring a uniform and complete coating, and improving the surface quality of the workpiece.

[0021] 2. This utility model integrates the spraying function of the spray head and the drying function of the air outlet within the sealed box through a mechanical workpiece drying component. Workpieces can be directly dried after being sprayed in the same equipment without needing to be transferred to other equipment, reducing process connection time. The hot air blown out by the hot air blower is precisely applied to the workpiece surface through the air outlet via the connecting pipe, accelerating the curing of the coating, significantly shortening the overall processing cycle and improving work efficiency. The triangular discharge trough at the bottom of the sealed box facilitates the collection of excess coating dripped during the spraying process. The first electric telescopic rod drives the high-temperature resistant steel coating scraper to scrape the residual coating at the bottom of the box into the discharge trough, where it is recycled and reused through the discharge pipe. This design reduces coating waste, lowers production costs, and keeps the inside of the sealed box clean, reducing cleaning workload. Attached Figure Description
