Description

Technical Field

[0001] This utility model relates to the field of hydraulic system technology, specifically a hydraulic system for makeup brushes. Background Technology

[0002] With the rapid development of the cosmetics industry, the market is placing increasingly higher demands on the quality, diversity, and production efficiency of makeup products. One of the core production steps for makeup brushes, especially powder products (such as eyeshadow brushes, blush brushes, and pressed powder), is pressing well-mixed loose powder raw materials into dense, smooth, and appropriately strong powder blocks. This pressing process is typically completed by a press driven by a hydraulic system.

[0003] Currently, the cosmetics industry commonly uses traditional hydraulic systems for powder pressing and molding. These systems typically consist of a motor, oil pump, directional valve, relief valve, hydraulic cylinder, and simple pressure control device. While they provide basic pressing capabilities, they are increasingly revealing many inherent shortcomings when facing the stringent requirements of high-end cosmetics production. Insufficient pressure control precision: Traditional hydraulic systems often use ordinary relief valves in conjunction with pressure gauges for pressure regulation, resulting in poor pressure stability and susceptibility to oil temperature changes and internal system leakage. This leads to differences in compaction density between different batches and even within the same batch of products, causing problems such as uneven product hardness, brittleness, powdering, and color variations, severely impacting product quality and consistency.

[0004] In addition, traditional hydraulic systems are cumbersome to adjust and slow to respond, making it difficult to quickly adapt to the flexible production needs of multiple varieties and small batches, especially the requirements for switching between fast and slow speeds.

[0005] Therefore, we propose a hydraulic system specifically for makeup brushes to solve the problems mentioned above. Utility Model Content

The oil pump 9 is a constant power pump. The bell-shaped cover 7 serves to protect the coupling 8 and also seals the connection to the oil pump 9 to ensure a sealing effect, enabling free switching between high pressure and low flow or low pressure and high flow. The oil pump 9 is connected to the inside of the oil tank 1 through a pipeline, and an oil suction filter 4 is installed in the pipeline. The motor 6 drives the oil pump 9 to draw oil from the oil tank 1 and filter it through the oil suction filter 4.

[0017] An air cooler 5 is also fixedly installed on the upper surface of the oil tank 1. The air cooler 5 is connected to the inside of the oil tank 1 and the oil pump 9 through a pipeline. The air cooler 5 cools the hydraulic oil from the oil tank 1 to the oil pump 9. A liquid level thermometer 17 is also installed on the oil tank 1. The main body of the liquid level thermometer 17 penetrates into the inside of the oil tank 1 to monitor the liquid level and liquid temperature in the oil tank 1 in real time and, together with the air cooler 5, to control the temperature of the hydraulic oil and ensure that the temperature of the oil tank 1 is around 45°C. The upper surface of the fuel tank 1 is also equipped with an oil passage block 19, a return oil filter 10, and a filler port 2; The oil circuit block 19 is connected to the oil pump 9 and the return oil filter 10 through pipelines. A first electromagnetic reversing valve 13 is fixedly installed above the oil circuit block 19 to switch the hydraulic oil flow direction between the oil circuit block 19 and the oil pump 9 and the return oil filter 10, and to control the flow rate of the hydraulic oil. Filler port 2 is used to replenish or extract hydraulic oil from oil tank 1; A check valve 11 is installed on the pipeline between the oil pump 9 and the manifold 19. An embedded pressure gauge 12 is also installed between the check valve 11 and the manifold 19 to monitor the pressure of the hydraulic oil between the check valve 11 and the manifold 19 in real time. The hydraulic oil drawn by the oil pump 9 is sent to the manifold 19 through the check valve 11, and then output and recovered through the manifold 19.

[0018] An oil level gauge 3 is also installed on one side of the oil tank 1. The oil level gauge 3 is used to monitor the oil level in the oil tank 1 in real time.

[0019] The hydraulic manifold 19 is provided with an oil inlet and an oil outlet, and a pressure relay 16 and a throttle valve 14 are installed on the hydraulic manifold 19.

The throttle valve 14 and the second solenoid directional valve 15 control the free switching of the hydraulic oil flow rate between the hydraulic manifold 19 and the hydraulic cylinder 18. The fastest speed can reach 0.5 m / min, and the slowest speed can reach 0.001 m / min. The pressure relay 16 is used to monitor the hydraulic oil pressure of the throttle valve 14, so as to realize the real-time adjustment of the hydraulic oil flow rate.

[0020] Working principle: The motor 6 is equipped with a constant power oil pump 9 to ensure free switching between high pressure and low flow or low pressure and high flow, which is suitable for adjusting the speed of makeup pen refill manufacturing. Motor 6 drives oil pump 9 to draw hydraulic oil from oil tank 1 and send it to oil circuit block 19. The flow rate, flow speed and direction are controlled by first solenoid directional valve 13. Then, throttle valve 14 and second solenoid directional valve 15 push it to oil cylinder 18 to make oil cylinder 18 work. The direction is switched by second solenoid directional valve 15 so that the hydraulic oil in oil cylinder 18 flows back to oil circuit block 19 and then flows back to oil tank through return oil filter 10. The oil pump 9, the air cooler 5 and the oil tank 1 form a closed loop channel, so that the hydraulic oil is cooled and its temperature is controlled by the air cooler 5.
