Embodiment 1

[0044] Example 1. A kind of dipping process method for condom production, as shown in Figure 1. 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 condo...

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 technological method and dipping equipments are used for producing condom. The method includes the steps of cleaning, gum dipping, exsiccating, demoulding, dunking and washing, drying, electric inspecting and packing of a model etc. The gum dipping includes the technological flows of dipping down and lifting up of the model, and the lifting up includes three to six sub-steps of three to six segments of liner or curvilinear lifting according to different oblique angle and different lifting heights. The equipments include a screw lifting rod, a dripping groove, latex, a machine frame, double up-turned and down-turned chain wheels, a motor, a double chain, a multi-chain plate, a model base, a model and a double-guideway. The double-guideway includes a dripping down segment and a lifting up segment. The lifting up segment includes three to six segments of liner or curvilinear segments according to different oblique angle and different lifting heights. The method and the equipments can solve the problem of the uniformity of the film and can produce the thin product to improve the sensitivity, comfort and pleasant feeling when using; at the same time the cost of the raw material is saved more than 10 percent, which greatly reduces the production cost; the method and the equipments can be widely applied to the production of a super-thin natural latex condom which achieves the international standard.

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. Its 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 dipping methods, it is divided into two-pass dipping equipment and three-pass dipping equipment. [0003] So far, no matt...
