[0033] Working principle:
[0034] In the cosmetics production process, the purity of raw materials is crucial, and an auxiliary structure of a raw material filtering device for cosmetics production plays an important role in improving the filtering effect and ease of use. The auxiliary structure is mainly composed of a filtering device body 1, a quick-connect assembly 2, a bellows 3, a limit assembly 4 and a sliding assembly 5.
[0035] The quick-connect assembly 2 provides a convenient way to connect the raw material delivery pipeline and the filtering device. When connecting the raw material delivery pipeline, the pipeline is inserted into the outer tube 21. After the pipeline slides into the outer tube 21, the plug 215 can be slid into the air guide tube 29. Then, the operator pushes the piston rod 25 downward through the push ring 24, so that the gas in the gas shell 27 enters the air bag 23 through the air guide tube 29, and the top spring 26 at the bottom of the push ring 24 is used to reset the position of the push ring 24. Since the air bag 23 is distributed in a circular array along the central axis of the outer tube 21, the air bag 23 gradually expands with the entry of gas, tightly hugging the inserted pipeline from multiple directions, realizing a quick connection. The circular array distribution The air guide tube 29 ensures that the gas can enter each air bag 23 evenly, providing a stable connection force for the pipeline connection. The air intake square tube 210 is used to replenish air for the air shell 27. The baffle 211 can prevent the gas from flowing back under the obstruction of the baffle frame 212, thereby preventing the gas from leaking out of the air intake square tube 210 when the gas is pressed into the air guide tube 29. The air blocking soft plate 213 also ensures that the gas will not flow back under the action of the baffle ring 214, thereby ensuring the stability of the connection. The setting of the handle 22 facilitates the operator to operate the quick-connect assembly 2. The inner tube 28 is used to limit the position of the pipeline, and the bellows 3 is connected between the two sets of quick-connect assemblies 2, which can play a role in buffering and adapting to the movement of the pipeline.
[0036] The limit assembly 4 is used to fix the position of the filter device body 1. The fixing block 41 is connected to the sliding rod 43 through the slider 42. The slider 42 can slide on the inner wall of the fixing block 41 to adjust the position of the sliding rod 43. The pressure rod 45 on the fixing rod 44 contacts the top of the filter device body 1 through the soft pad 46. When the position of the filter device body 1 needs to be fixed, the pressure rod 45 is pressed downward, and the pressure rod 45 drives the sliding block 42 to slide in the fixing block 41. As the pressure rod 45 is pressed downward, the contact between the soft pad 46 and the filter device body 1 becomes closer, playing a fixing role. After adjusting to the appropriate position, the position of the pressure rod 45 is fixed by the limit plate 47 and the locking bolt 48. The limit plate 47 is connected to the locking bolt 48 through a thread. When the locking bolt 48 is tightened, it will resist the outer wall of the sliding rod 43 to fix the position of the sliding rod 43. In this way, the entire limit assembly 4 can fix the filter device body 1 to prevent it from moving during operation.
[0037] The sliding assembly 5 is used to move the position of the filter device body 1. The positioning block 51 in the mounting block 52 can cooperate with the plug block 53. When the filter device body 1 needs to be moved, the plug block 53 can be inserted into the inner wall at the bottom of the positioning block 51, and then the position of the plug block 53 is fixed by the clamping block 54. The clamping block 54 is fixedly connected to the outer wall of the mounting block 52, which can prevent the plug block 53 from escaping from the positioning block 51. The pulley 55 at the bottom of the mounting block 52 can make the filter device body 1 easy to move. The setting of the pulley 55 enables the filter device body 1 to be more conveniently switched between different working positions, thereby improving the flexibility of production. The top of the positioning block 51 is fixedly connected to the bottom of the fixing block 41, thereby connecting the limit assembly 4 and the sliding assembly 5 together to form a whole. The limit assembly 4 adopts a modular setting. Therefore, when the pulley 55 needs to be replaced, it is only necessary to contact the locking of the plug block 53 by the clamping block 54, and then slide the mounting block 52 out of the positioning block 51 to quickly replace the pulley 55.
