Description

Improved condom lubricant on-line coating device

Technical Field

The utility model belongs to the technical field of condom production, in particular to an on-line lubricant coating device in the condom production process.

Background

The condom is an effective means for implementing birth control and preventing venereal disease and AIDS infection.

Condom products currently on the market generally have the problem of insufficient lubrication of the collar (the wound portion), even without lubricant in the portion near the open end of the condom. The problem is mainly caused by an oiling process in the condom production process, and the process comprises the following steps: on the production line, the condom is wound firstly, then the oil dripping process is carried out, the lubricant is dripped at the top end part of each wound condom, and then the condom is packaged singly. The condom collar (wound portion) is in a wound state at this time, and the lubricant slowly permeates into the wound portion from the tip portion. The permeation time is usually long, and is generally 3-6 months; and the permeation effect is very uneven. Thereby increasing product inventory pressure.

In order to assist in lubricant penetration, the industry has added a powdering step before the condom is wound, and added a layer of lubricant powder on the outside of the condom. However, this adds an additional substance to the condom, which is not safe and therefore has been eliminated.

CN201261264Y and CN207204465U disclose "a device for filling lubricant during condom production" and "a modified device for filling lubricant during condom production", respectively, to adjust the lubricant applying process before the condom is wound.

CN201261264Y "oiling device in the condom production process" adopts the mode: before the coiling process of the condom production line, an oil groove is arranged below the steel die and is used for containing lubricating oil and an oil absorption soft body, when the steel die is used for oiling, the steel die descends to enable the outer side of the condom to be dipped with oil, and then the coiling process is carried out.

Patent CN207204465U "improved generation filling device in condom production process" adopts the mode the same with patent CN201261264Y "improved generation filling device in condom production process", and its patent improves its oil groove setting, improves to a plurality of oil grooves by an oil groove to reach and to separate the cell body and place and hold lubricating oil, the lubricating oil of each partition cell body is same kind or different.

However, although the above scheme can dip the surface of the condom with lubricant, it has disadvantages, which are specifically shown in:

1) in the production process, along with the consumption of the lubricant in the oil groove, the liquid level is gradually reduced, and the oil content in the oil absorption soft body is continuously changed, so that the lubricant content of products produced before and after the same production process is inconsistent;

2) in the soft body for absorbing the lubricant, the lubricant content at the position close to the oil penetration hole is relatively high, while the lubricant content at the position far from the oil penetration hole is low or possibly none, so that the lubricant content at different positions in the same product in actual production is inconsistent;

3) due to the preparation process of the oil absorption soft body material, the adsorption amount of the lubricant at different positions on the surface of the oil absorption soft body is different. This difference has little effect on the product when the coating amount is large, but when the coating amount is low, the lubricant distribution on the surface of the product is very uneven, and even the lubricant is not locally available.

4) In the process of coating the lubricant, the absorption of the lubricant needs to extrude the oil absorption soft body by using a die sleeved with a condom. However, due to the non-uniform absorption of the lubricant by the oil-absorbing soft body and the manufacturing precision error of the die, the transfer amount of the lubricant at different positions on the surface of the oil-absorbing soft body is not uniform when the condom is coated by 8 processes, thereby causing the non-uniform lubricant on the surface of the condom.

5) The effect of applying the lubricant to the surface of the condom cannot be designed and cannot be fully achieved by applying the lubricant only to the portion where the lubricant is desired.

CN106391391A discloses an "oiling device in production process", which adopts the design of oil storage tank and oil inlet pipe, uses metering pump as conveying device, and designs the lubricant coating block into vertical cylinder. The design can improve the distribution of the lubricant content in the lubricant coating block, but in practical application, when the die sleeved with the condom passes through the cylinder, the closer to the central axis of the cylinder, the higher the pressure on the lubricant coating block is, the more the extruded and exuded lubricant is, the more uniform distribution cannot be realized, and the more the die can not be coated according to requirements.

Thus, there is a need for an in-line applicator for condom lubricants that can be applied uniformly, on-demand.
