Description

Welding Die for Double Hose Mouth Tube with Buffer Tank

technical field

The utility model relates to an orifice pipe welding mold, in particular to a double-hose mouth pipe welding mold with buffer grooves.

Background technique

There are mainly two types of packaging forms of large infusion soft bags popular in the market now: one is a single-mouth tube soft bag, and the other is a double-tube soft bag. Due to the separation of the dosing port and the injection port of the double-hose soft bag, it is easy to realize the production of anaerobic drugs, and the advantages of high pricing and large profits have gradually attracted the attention of pharmaceutical factories and have achieved rapid development.

In the actual production of double-hose soft bags, the hose needs to be welded twice and once shaped to be welded together with the membrane material. As the core component, the mouth tube welding mold has a decisive influence on the quality of the soft bag. The soft bag welded by the existing mouth tube welding mold is prone to slight liquid leakage at the root of the hose. The reason is that during the mouth tube welding process, the stretching rate of the membrane material is too large, and at the same time, it is affected by high temperature and high pressure. The internal structure of the material is damaged and loses its original physical properties.

Utility model content

According to the deficiencies in the prior art above, the technical problem to be solved by the utility model is: to provide a double-hose mouth tube welding mold with a buffer tank, so that the membrane material can reduce the damage to the membrane material during the mouth tube welding process. damage, and reduce the leakage rate of the double-hose soft bag during production.

The welding mold for double-hose mouth pipes with buffer grooves described in the utility model includes a welding mold base body, two concave cylindrical surfaces are arranged on the welding mold base body, and a semicircular buffer groove is arranged on the cylindrical surface along the circumferential direction .

Wherein, three semicircular buffer grooves are preferably arranged on the cylindrical surface along the circumferential direction.

Working process and principle of the present utility model:

When heating and pressurizing the membrane and the hose, due to the existence of the buffer tank, the membrane at the corresponding position is not affected by high temperature and high pressure, and the physical properties are not affected. At the same time, this part maintains the original physical properties. The high-performance membrane material has a compensating effect on other membrane materials under pressure and heat, which strengthens the strength of the membrane material on the entire welding surface, ensures the welding effect of the membrane material and the hose, and reduces the leakage rate.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. During the welding process, due to the existence of the buffer tank, the influence of the mold on the high temperature and high pressure of the membrane material corresponding to the buffer tank can be reduced, and the physical properties of the original membrane material are maintained.

2. The welding surface of the soft bag hose after welding has a ring-shaped convex ring, which makes the whole bag look beautiful and exquisite.

3. It can reduce the leakage rate caused by equipment factors.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1 to 4, the double-hose mouth pipe welding mold with a buffer tank described in the utility model includes a welding mold base 1, and two concave cylindrical surfaces 2 are arranged on the welding mold base 1, and the cylindrical surface 2 is provided with three semicircular buffer grooves 3 along the circumferential direction.

Working process and principle of the present utility model:

When welding the membrane material 4 and the hose 5 under heat and pressure, due to the existence of the buffer tank 3, the membrane material 4 at the corresponding position is not affected by high temperature and high pressure, and its physical properties are not affected. At the same time, this part remains The membrane material 4 with the original physical properties has a compensating effect on other membrane materials 4 under pressure and heat, which strengthens the strength of the membrane material 4 on the entire welding surface, ensures the welding effect of the membrane material 4 and the hose 5, and reduces the Leakage rate.

In addition, there are three annular convex rings on the welding surface of the soft bag hose after welding, which makes the whole bag look more beautiful and exquisite.
