Description

Technical Field

[0001] This utility model relates to the field of lubricant filling technology, and in particular to a lubricant filling structure for self-heating condom packaging. Background Technology

[0002] With the widespread use of condoms in the medical and personal care fields, lubricants are increasingly being added to condom packaging to enhance user experience and product value. The precise dispensing of lubricant directly affects product performance and is also related to cost control and quality stability. Therefore, developing a device capable of efficient, precise, and clean lubricant dispensing is of significant practical importance and application prospects. This invention provides a self-heating lubricant dispensing structure for condom packaging, aiming to solve the technical problems of low accuracy and cleaning difficulties associated with traditional dispensing methods.

[0003] Currently, most lubricant dispensing equipment on the market uses a plunger pump or pneumatically driven dispensing system, which pushes the lubricant from the storage chamber to the target packaging container through the reciprocating motion of a piston. Its structure typically includes a storage cylinder, a dispensing channel, and a dispensing head, with the dispensing volume mainly determined by piston stroke control or time control. Furthermore, to prevent impurities in the lubricant from clogging the system, some devices have a filter or buffer chamber before dispensing to stabilize the flow rate. However, this type of structure has significant errors in controlling the accuracy of lubricant dispensing, and after repeated use, the storage cylinder is prone to sedimentation or stratification due to long-term lubricant retention, resulting in high cleaning and maintenance costs.

[0004] However, existing lubricant dispensing equipment generally suffers from inaccurate lubricant dispensing quantity control during use. This is particularly problematic when dispensing lubricant into condom packaging, where structural limitations make it prone to under- or over-dispensing, impacting product consistency and user experience. Therefore, there is an urgent need for a lubricant dispensing structure capable of precisely controlling the dispensing volume and possessing excellent self-cleaning capabilities to improve automation and dispensing reliability. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a self-heating lubricant filling structure for condom packaging, aiming to improve the problem of inaccurate control of the amount of lubricant used during traditional lubricant filling.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a self-heating lubricant filling structure for condom packaging, comprising a storage cylinder, wherein a discharge pipe is fixedly connected to the bottom of the storage cylinder, and a metering component is provided at one end of the discharge pipe.

[0007] The metering component includes a housing, the outer wall of which is fixedly connected to one end of a discharge pipe. A drive assembly is provided on the outer wall of a storage cylinder. A storage pipe is fixedly connected to the top of the housing. A piston is slidably connected inside the storage pipe. A connecting plate is fixedly connected to the top of the piston.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, firstly, the output end of the electric push rod two extends out and drives the metering cylinder to rotate through the connecting rod, so that the metering cylinder seals the connection between the discharge pipe one and the shell. Then, the output end of the electric push rod one extends out and drives the piston to press down, thereby pushing the lubricant into the discharge pipe two to add to the condom packaging, achieving the effect of quantitative dispensing. This solves the problem that the amount of lubricant cannot be accurately controlled when adding lubricant in the traditional way, and improves the accuracy of lubricant dispensing.

[0024] 2. In this utility model, the spiral blade agitates the lubricant inside the storage cylinder, and the horizontal stirring rod agitates the lubricant inside the storage cylinder laterally.

[0035] Reference Figure 4 and Figure 5A motor 14 is fixedly connected to the top of the storage cylinder 1, serving as a power source to drive the internal stirring and scraping structure. A rotating shaft 15 is fixedly connected to the output end of the motor 14, transmitting the rotational power of the motor 14 to the stirring device inside the storage cylinder 1. A scraper 16 is fixedly connected to the outer wall of the rotating shaft 15, scraping off the lubricant adhering to the inner wall of the storage cylinder 1 to prevent residue and deposition. The outer wall of the scraper 16 fits against the inner wall of the storage cylinder 1 to ensure thorough scraping and improve the cleanliness of the cylinder.
