Embodiment 1

[0044] Example 1. A kind of dipping process method for condom production, such as figure 1 shown. This embodiment includes the steps of model cleaning, first dipping, drying, second dipping, drying, third dipping, drying, mold removal, soaking, drying, electrical inspection and packaging. The dipping step includes the dipping and lifting process of the model, and the lifting process includes the corresponding 5 sub-steps of lifting according to 5 sections of straight lines or curves with different inclinations and different lifting heights to improve the uniformity of the condom. sex. At the same time, the consumption of raw materials can be saved, and the production cost can be greatly reduced.

[0045] The 5 sub-steps of the lifting process are:

[0046] (1) After the model is turned from dipping to lifting, use a short straight line with a large inclination to lift to a small height to speed up the lifting speed so that the latex and thickness of the weak part of the co...

Embodiment 2

[0052] Example 2. A dipping process method for condom production. Wherein, the lifting process includes three corresponding sub-steps of lifting according to three sections of straight lines or curves with different bevel angles and different lifting heights, so as to improve the uniformity of the condom.

[0053] The 3 sub-steps of the lifting process are:

[0054] (1) After the model is turned from dipping to lifting, use a short straight line with a large inclination to lift to a small height to speed up the lifting speed so that the latex and thickness of the weak part of the condom will increase significantly;

[0055] (2) Raise the model to a relatively high height with a small oblique angle and a long straight line, and keep a slow lifting speed to make the latex at the weaker part near the middle part of the condom more uniform and correspondingly increase, and the thickness is correspondingly increased;

[0056] (3) Raise the model to a middle height with a curve wi...

Embodiment 3

[0058] Example 3. A dipping process method for condom production. Wherein, the lifting process includes 6 corresponding sub-steps of lifting according to 6 sections of straight lines or curves with different bevel angles and different lifting heights, so as to improve the uniformity of the condom.

[0059] The 6 sub-steps of the lifting process are:

[0060] (1) After the model is turned from dipping to lifting, use a short straight line with a large inclination to lift to a small height to speed up the lifting speed so that the latex and thickness of the weak part of the condom will increase significantly;

[0061] (2) Raise the model to a relatively high height with a small oblique angle and a long straight line, and maintain a slow lifting speed so that the latex in the middle part of the condom near the opening is appropriately increased, and the thickness is appropriately increased;

[0062] (3) Raise the model to a smaller height with a curve with a smaller slope and l...

Abstract

A dipping process method and dipping equipment for condom production. The method includes the steps of model cleaning, glue dipping, drying, demoulding, soaking, drying, electric inspection and packaging. Dipping includes the process of dipping and lifting the model, and lifting includes 3-6 sub-steps of 3-6 sections of straight line or curved lifting according to different bevel angles and different lifting heights. The equipment includes spiral lifting rod, dipping tank, latex, frame, double up and down sprockets, motor, double chain, multi-chain plate, model base and model, double guide rail. The double guide rails include the dipping section and the lifting section, and the lifting section includes 3-6 straight or curved sections with different inclination angles and different lifting heights. It can solve the problem of homogenization of the film, produce thin products, improve the sensitivity, comfort and pleasure of use; at the same time save more than 10% of raw material consumption, greatly reducing production costs. It can be widely used in the production of international-level ultra-thin natural rubber latex condoms.

Description

technical field [0001] The invention belongs to the technical field of condoms, and more specifically relates to the innovation of a dipping process for condom production and dipping equipment. Background technique [0002] At present, domestic male condoms are mostly made of natural rubber latex, which is a relatively mature contraceptive device, and they are all manufactured by dipping technology. The production equipment can be divided into two types according to different operation modes: vertical vertical operation type and horizontal balance operation type. The applicant is the patent holder of the horizontal balance operation type production equipment, and the patent number is 01261740.7. According to the different assembly forms of mold fixtures, it can be divided into double combination and single combination. In addition, due to the different impregnation methods, it is divided into two-pass impregnation equipment and three-pass impregnation equipment. [0003] S...
