Technical Field

[0001] This utility model relates to the field of dispensing device technology, specifically a lubricant dispensing device. Background Technology

[0002] Lubricant repackaging technology refers to a series of processes that involve filling large-capacity storage of various lubricating greases or oils into small containers (such as bottles, cans, barrels, and tubes) according to a predetermined precise volume or weight. This step is an indispensable and crucial one between the production and manufacturing of lubricant products and their use by end users, directly affecting the product's ease of use, storage stability, measurement accuracy, and the end-user experience. Existing lubricant dispensing technologies still face numerous challenges and limitations. Firstly, regarding metering accuracy, especially for high-viscosity greases or complex formulations containing special additives, insufficient filling or overflow is prone to occur. Secondly, complex cleaning procedures and lengthy maintenance times lead to decreased production efficiency. Furthermore, the sealing and anti-contamination designs of existing equipment still need improvement; lubricant exposure to the environment during filling can easily lead to cross-contamination risks. Therefore, we propose a lubricant dispensing device. Utility Model Content

[0005] Furthermore, the filter assembly includes a guide tube, a slip ring, a filter screen, a sealing cap, and connecting strips. The lower end of the outlet tube is fixed with a guide tube, and the upper end of the guide tube is slidably connected with a slip ring. The upper end of the slip ring has a groove, and the filter screen is placed inside the groove. The upper end of the circumferential surface of the slip ring is threaded with a sealing cap, and the sealing cap has an opening in the middle. The sealing cap fits against the upper end of the filter screen. The lower end of the slip ring is fixed with two corresponding connecting strips. By setting up the filter assembly, it is convenient to filter the dispensed lubricating oil.

[0006] Furthermore, the connecting assembly includes a connecting block, a connecting rod, and a connecting ring. The connecting ring is fitted onto the circumferential surface of the guide tube.

[0015] The working principle of the lubricant dispensing device provided by this utility model is as follows: First, the lubricant to be dispensed is injected into the storage tank 41. The liquid level sensor 42 monitors the liquid level of the lubricant in the tank in real time and feeds the data back to the external PLC controller. When dispensing is required, the external PLC controller controls the solenoid valve 44 to open according to the preset quantitative parameters. The lubricant in the storage tank 41 flows into the filter assembly 5 below through the outlet pipe 43 under the action of gravity. The lubricant first enters the guide pipe 51 and flows through the filter screen 53 placed in the groove at the upper end of the slip ring 52. The filter screen 53 intercepts and filters impurities in the lubricant to ensure the purity of the dispensed lubricant. The filtered lubricant finally flows into the container placed in the placement tank 3 through the lower port of the guide pipe 51 to complete the dispensing. During the dispensing process or when maintenance is required, it can be controlled by the external PLC controller. The PLC controller starts the electric telescopic rod 72 of the adjustment component 7. The telescopic arm of the electric telescopic rod 72 drives the fixed plate 73 and the connecting ring 63 fixed thereto to move up and down. The connecting ring 63 slides in the guide tube 51 through the linkage of the connecting rod 62 and the connecting block 61 with the slip ring 52. When the slip ring 52 is pulled down to be completely removed from the guide tube 51, the user can unscrew the threaded sealing cover 54 to easily take out the filter screen 53 in the groove for cleaning or replacement. It is worth noting that during the movement of the slip ring 52, the rubber ring 8 fixed in the annular groove on its circumference will fit tightly against the inner wall of the guide tube 51 and rub against it, automatically scraping off the residual lubricant or impurities attached to the inner wall, playing an auxiliary cleaning role. After the maintenance is completed, the adjustment component 7 can be reversed to reset the slip ring 52 and the filter screen 53 to the working position inside the guide tube 51. The entire dispensing process achieves quantitative control of lubricant, online filtration, and convenient maintenance and self-cleaning of key components. During dispensing, the baffle 2 can be closed to seal the dispensing box 1, preventing external residues from entering and contaminating the lubricating oil.

[0016] It is worth noting that the external PLC controller disclosed in the above embodiments is specifically a Siemens S7-200. The hydraulic sensor 42, solenoid valve 44 and electric telescopic rod 72 can be freely configured according to the actual application scenario. The external PLC controller controls the operation of the solenoid valve 44 and the electric telescopic rod 72 using methods commonly used in the prior art.
