A rotating support for improving coating uniformity

Abstract

This utility model discloses a rotating bracket for improving the uniformity of spraying. The rotating bracket is driven by a motor to rotate the turntable continuously, which drives the workpieces on multiple workpiece positioning mechanisms to rotate synchronously. With the help of multiple nozzles evenly distributed by the flow divider, the bracket performs all-round spraying, which fundamentally ensures the uniformity and integrity of the coating on the workpiece surface. The circumferential array drying mechanism realizes the synchronous drying of batch workpieces through multiple adjustable partitions. Combined with the directional exhaust pipe and liquid-absorbing sponge layer, the bracket effectively collects volatile gases and dripping paint while accelerating the curing of the coating, which greatly reduces environmental pollution. This application integrates spraying, rotating positioning and drying functions into one unit. Through the automation process, it not only significantly improves the work efficiency, but also comprehensively optimizes the stability of coating quality and the environmental friendliness of production.

Description

Technical Field

[0001] This utility model belongs to the technical field of spraying equipment and relates to a spraying bracket, specifically a rotating bracket for improving the uniformity of spraying. Background Technology

[0002] In industrial production, spraying is widely used for surface treatment of various workpieces to achieve purposes such as corrosion prevention, decoration, or imparting specific functions. However, traditional spraying methods often suffer from problems such as poor coating uniformity, low efficiency, and susceptibility to environmental pollution. Specifically, for batch workpieces, especially those requiring multi-sided spraying, a fixed spraying method is often used, which easily leads to uneven coating thickness on the workpiece surface, resulting in defects such as runs, missed areas, or excessively thick coatings in certain areas. Furthermore, the drying process after spraying is usually carried out directly in the workshop, which not only occupies extra space and time but also lacks effective measures for collecting volatiles and treating dripping paint. This not only prolongs the overall process cycle but also easily causes paint volatiles to diffuse into the work environment, affecting the health of operators and polluting the environment. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes a rotating bracket for improving the uniformity of spraying, which integrates efficient and uniform spraying, flexible workpiece positioning and environmentally friendly air drying functions, effectively improving spraying quality and production efficiency.

[0004] The objective of this utility model can be achieved through the following technical solutions: A rotating support for improving coating uniformity includes: a coating box, a workpiece positioning mechanism, and spray nozzles. The coating box contains a turntable rotatably connected to the bottom plate of the coating box and driven by a motor. Multiple workpiece positioning mechanisms are mounted on the turntable to position and fix multiple workpieces. A paint tank is mounted on the top plate of the coating box, and pump bodies are connected to both sides of the paint tank. The pump bodies are connected to a flow divider plate via hoses. The flow divider plate is mounted on the side plate of the coating box, and multiple spray nozzles are evenly distributed on the flow divider plate. One end of each spray nozzle is connected to the flow divider plate, and the other end extends through the side plate of the coating box into the coating box to perform coating operations on the workpieces positioned and fixed on the turntable.

[0005] Furthermore, the motor is installed below the spray box, and the turntable is connected to the motor through a rotating shaft passing through the bottom plate of the spray box.

[0006] Furthermore, the workpiece positioning mechanism includes: a U-shaped plate, a clamping rod, and a positioning plate. The U-shaped plate is fixedly installed on the turntable, and the positioning plate is connected to the U-shaped plate through the clamping rod. The workpiece is positioned and fixed on the positioning plate.

[0007] Furthermore, one end of the clamping rod is rotatably connected between the two side plates of the U-shaped plate via a rotating rod, and the other end is connected to the positioning plate. The side of the positioning plate connected to the clamping rod is provided with a clamping groove. The clamping rod is inserted into the clamping groove and detachably connected to the positioning plate. The clamping rod and the clamping groove are interference fit.

[0008] Furthermore, a through groove is provided in the middle of the positioning plate, and a first clamping plate and a second clamping plate are movably connected in the through groove. Both the first clamping plate and the second clamping plate can slide along the extension direction of the through groove and can be locked and fixed to clamp and fix the workpiece between the first clamping plate and the second clamping plate.

[0009] Furthermore, it also includes multiple drying mechanisms to dry the workpieces after the spraying operation is completed. The multiple drying mechanisms are arranged in a circular array around the periphery of the spraying box, and the drying mechanisms are connected to the side plates of the spraying box through fixed rods.

[0010] Furthermore, the drying mechanism includes a drying box, a fan, and an exhaust pipe. The fan is located on one side of the drying box to transfer the workpiece that has completed the spraying operation into the drying box and assists in drying. The exhaust pipe is located on the top of the drying box to directionally exhaust the paint that evaporates during the drying process.

[0011] Furthermore, the drying chamber is equipped with multiple layers of partitions to allow multiple workpieces to be placed on the partitions and dried simultaneously. The two ends of the partitions are detachably connected to the side walls of the drying chamber by screws.

[0012] Furthermore, a layer of absorbent sponge is laid on the partition plate to absorb the paint that will flow down the workpiece.

[0013] The beneficial effects of this utility model are as follows: The rotating bracket provided in this application for improving the uniformity of spraying uses a motor to drive the turntable to rotate continuously, which in turn drives the workpieces on multiple workpiece positioning mechanisms to rotate synchronously. With the help of multiple nozzles evenly distributed by the flow divider, it can carry out all-round spraying, which fundamentally ensures the uniformity and integrity of the coating on the workpiece surface. The circumferential array drying mechanism realizes the synchronous drying of batch workpieces through multiple adjustable partition plates. Combined with the directional exhaust pipe and liquid-absorbing sponge layer, it can effectively collect volatile gases and dripping paint while accelerating the curing of the coating, which greatly reduces environmental pollution. This application integrates spraying, rotating positioning and drying functions into one, which not only significantly improves the work efficiency through the automation process, but also comprehensively optimizes the stability of coating quality and the environmental friendliness of production.

Multiple workpiece positioning mechanisms 2 are installed on the turntable 4 to respectively position and fix multiple workpieces.

[0020] A paint tank 6 is installed on the top plate of the spray box 1. Pump bodies 7 are connected to both sides of the paint tank 6. The pump bodies 7 are connected to the diverter plate 9 through the hose 8. The diverter plate 9 is installed on the side plate of the spray box 1. Multiple nozzles 10 are evenly distributed on the diverter plate 9. One end of the nozzle 10 is connected to the diverter plate 9, and the other end passes through the side plate of the spray box 1 and extends into the spray box 1 to perform spraying operations on the workpieces positioned and fixed on the turntable 4.

[0021] Multiple drying mechanisms 3 are arranged in a circular array around the spray box 1 to dry the workpieces after the spraying operation is completed. The drying mechanisms 3 are connected to the side plate of the spray box 1 by a fixing rod 11.

[0022] like Figure 2As shown, the workpiece positioning mechanism 2 includes a U-shaped plate 21, a clamping rod 22, and a positioning plate 23. The U-shaped plate 21 is fixedly mounted on the turntable 4. The positioning plate 23 is connected to the U-shaped plate 21 via the clamping rod 22, and the workpiece is positioned and fixed on the positioning plate 23. One end of the clamping rod 22 is rotatably connected between the two side plates of the U-shaped plate 21 via a rotating rod 24, and the other end is connected to the positioning plate 23. A slot is provided on the side of the positioning plate 23 connected to the clamping rod 22. The clamping rod 22 is inserted into the slot and detachably connected to the positioning plate 23. The clamping rod 22 and the slot are interference-fitted. A through groove 25 is provided in the middle of the positioning plate 23. A first clamping plate 26 and a second clamping plate 27 are movably connected in the through groove 25. Both the first clamping plate 26 and the second clamping plate 27 can slide along the extension direction of the through groove 25 and be locked and fixed by bolts to clamp and fix the workpiece between the first clamping plate 26 and the second clamping plate 27.

[0023] like Figure 3 As shown, the drying mechanism 3 includes a drying chamber 31, a fan 32, and an exhaust pipe 33. The fan 32 is located on one side of the drying chamber to transfer the workpieces after spraying into the drying chamber 31 for drying. The fan 32 assists in the drying process. The exhaust pipe 33 is located at the top of the drying chamber 31 to directionally exhaust the paint that evaporates during the drying process. The drying chamber 31 is equipped with multiple layers of partitions 34 to allow multiple workpieces to be placed on the partitions 34 for simultaneous drying.

Then, the motor 5 below the spray box 1 is turned on, driving the turntable 4 to rotate, which in turn causes the multiple workpieces positioned and fixed on the turntable 4 to rotate. Finally, the pump bodies 7 on both sides of the paint tank 6 are turned on, and the paint in the paint tank 6 is transported through the hose 8 to the diversion plate 9 via the pump bodies 7. The paint is distributed to multiple nozzles 10 by the diverter plate 9, and continuous spraying is performed on the workpieces that rotate with the turntable 4. This allows for simultaneous rotational spraying of multiple workpieces, improving spraying efficiency and ensuring the uniformity and integrity of the spraying. In addition, to enable the paint on the workpieces to dry quickly, the workpieces that have been sprayed can be transferred to the partition plate 34 inside the drying box 31, and the fan 34 on one side of the drying box 31 can be turned on to blow air into the drying box 31 to dry the workpieces on the partition plate 34. During the drying process, the evaporated paint can be directionally discharged through the exhaust pipe 33, effectively preventing the paint from escaping to the outside of the drying box 31 and protecting the environment of the spraying operation.
