Problems solved by technology

But its disadvantages are: 1. Its flexible plastic packaging is composed of two cylindrical films nested together, which is difficult to realize automation and the production cost of glue filling is relatively high.
2. The flexible packaging plastic shell and propulsion device used (the soft packaging plastic shell and the propulsion device are actually two components of a larger glue gun) are more complicated and expensive

Embodiment

[0027] Simple no-mix two-component one-packs of adhesives such as figure 1 and figure 2 As shown, a static mixer 10, a soft plastic package 20, and a rubber cartridge 30 are included. Wherein, described static mixer 10 is as image 3 As shown, it consists of a mixed shell 11 and a mixed double helix core 12. The front end of the mixing shell 11 is a nozzle, the middle is a cylinder, and the inner wall of the rear end is threaded. The mixing double-helix core 12 is a double-helix structure with opposite directions, and its outer diameter is slightly smaller than the cylinder in the middle of the mixing shell 11 .

[0028] Described soft plastic package 20 such as Figure 4 and Figure 5 As shown, two film tubes 22 are welded around two welding points 21 by a piece of film, and there are tie-down heads 23 at its two ends. Two film cartridges 22 each pack a component of the sealing adhesive. The size ratio of the two film tubes 22 is adjustable to meet the ratio requireme...

Embodiment 2

[0032] The rubber cartridge 40 is as Figure 10 As shown, it can be replaced by a soft plastic bag 41 and a movable cover 42. The soft plastic bag 41 is a straight film with a cavity in the middle. One end is welded with the movable cover 42, and the other end is welded or fastened. The movable cover 42 and Figure 7 The movable cover 32 shown is similar. outline.

Embodiment 3

[0034] The movable cover 60 is as Figure 11 As shown, the inner body is a conical cavity 61 . One side of the conical cavity 61 is a step 62 . The other side of the tapered cavity 61 is a glue outlet 63 . The outer wall of the glue outlet 63 has threads 64 .

Abstract

The invention relates to a simple-type unmixed bi-component single package for an adhesive. The simple-type unmixed bi-component single package is characterized by comprising a static mixer, a flexible plastic package and a glue cylinder, wherein the flexible plastic package is welded into two film cylinders by surrounding two welding points by a film, both ends of the flexible plastic package are respectively provided with a fastening head, and the two film cylinders are respectively used for packaging and sealing one component of the adhesive; the glue cylinder comprises a cylinder, a movable cover and a piston, wherein one end of the cylinder is connected with the step of the movable cover, and the inner wall at the other end of the cylinder is connected with the piston; the inner wall of the glue cylinder is connected with the flexible plastic package, a glue outlet of the movable cover of the glue cylinder is connected with the mixed shell of the static mixer. The simple-type unmixed bi-component single package has the beneficial effects that the two components of the adhesive are respectively packaged, so that the adhesive has a stable chemical property and a long storage life; when the adhesive is extruded for use, the two components can be mixed into a whole body, so that the adhesive has good adhesive performance and is convenient to use; moreover, the glue-pouring production cost is lower, a flexible plastic package glue shell and a propelling device which are used are simpler and cheaper.

Description

technical field [0001] The present invention relates to packaging of sealing adhesives, in particular non-mixing two-component single packaging of sealing adhesives. Background technique [0002] Sealing adhesives generally consist of two components, A and B. When the two components exist alone, there is no viscosity and the chemical properties are stable. When the two components are mixed, a chemical reaction will occur and it will be viscous, but as time goes by, it will harden and gradually reduce or lose its viscosity, reducing or disappearing the use value. Therefore existing main packing has two kinds of forms: the one, hard shell, plastic packing tube (or paper tube) with nozzle, or toothpaste formula packing. The A and B components of the packaging sealing adhesive have been mixed and can be used. Its advantage is that it is convenient to use, but its disadvantage is that it must be used within a certain period of time, and it will become invalid when it expires. ...
