AI Technical Summary
When preparing stretching specimens of adhesive strips, if the adhesive dispensing from the mixing tube is too thin, the specimen near the bottom of the mold will have insufficient adhesive, resulting in low sample preparation efficiency and low yield. This is especially true for thixotropic adhesives with poor flowability, which require skilled application techniques to compensate for the insufficient adhesive.
A glue application nozzle for assisting in the preparation of stretching specimens was designed, including a connecting nozzle, a glue dispensing nozzle, and a glue outlet. The glue outlet is a long strip or rectangle corresponding to the shape of the mold to ensure uniform glue distribution. It is fitted onto the glue dispensing tube to achieve a wide range of glue dispensing.
By improving the adhesive applicator nozzle structure, uniform adhesive distribution was achieved, reducing the defect rate and improving sample preparation efficiency and yield.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of adhesives, specifically relating to an adhesive applicator nozzle for assisting in the preparation of stretching specimens. Background Technology
[0002] When preparing stretching specimens from adhesive strips, the excessively thin adhesive dispensing from the mixing tube (dispensing tube) makes application difficult, often resulting in insufficient adhesive near the bottom of the mold and rendering the specimens unusable. In actual adhesive application and sample making, free-flowing adhesives can fill the mold on their own, but for thixotropic adhesives with poor flowability, only skilled application techniques can compensate for insufficient adhesive, leading to low sample making efficiency and a low yield. Utility Model Content
[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a glue applicator nozzle for assisting in the preparation of stretching specimens.
[0004] To achieve the above and other related objectives, this utility model provides a glue application nozzle for assisting in the preparation of stretching strips. The nozzle includes a connecting nozzle for connecting with a glue dispensing tube and a glue dispensing nozzle connected to the connecting nozzle. The connecting nozzle includes an inlet, an outlet, and a connecting part located between the inlet and the outlet. The glue dispensing nozzle is fixedly connected to and communicates with the outlet. The glue dispensing nozzle has an elongated or rectangular glue dispensing outlet.
[0005] Optionally, the connector is a cylindrical connector, and the inlet is a conical inlet that gradually narrows from the outside to the inside.
[0006] Optionally, the dispensing nozzle is a cuboid dispensing nozzle, and the dispensing opening is a square pyramidal dispensing opening that gradually expands in diameter from the inside out.
[0007] Optionally, the inlet end of the connector is further provided with a connecting ring for connecting with the dispensing tube. The dispensing tube has a protrusion protruding from the outer wall of the dispensing tube, and the connecting ring has an "L"-shaped groove for the protrusion to be engaged.
[0008] As described above, the glue application nozzle for assisting in the preparation of stretching specimens of this utility model has the following beneficial effects: When using the glue application nozzle for assisting in the preparation of stretching specimens of this utility model, the connecting nozzle of the nozzle is connected to the glue outlet tube. During the glue dispensing process, the glue flows out from the inlet, outlet, glue outlet nozzle, and glue outlet. Since the glue outlet is a long strip or rectangle corresponding to the shape of the mold, the glue dispensing can be wider and directly fit into the inner groove of the mold, which is convenient and quick and can greatly reduce the defect rate.

[0015] like Figure 1-3 As shown, this embodiment provides a glue application nozzle for assisting in the preparation of stretching strips. The nozzle 10 includes a connecting nozzle 12 for connecting with a glue dispensing tube 11, and a glue dispensing nozzle 13 connected to the connecting nozzle 12. The connecting nozzle 12 includes an inlet 14, an outlet 15, and a connecting portion 16 located between the inlet 14 and the outlet 15. The glue dispensing nozzle 13 is fixedly connected to and communicates with the outlet 15. The glue dispensing port 17 of the glue dispensing nozzle 13 is an elongated or rectangular glue dispensing port 17.
[0016] Preferably, the adhesive applicator nozzle 10 is integrally molded from silicone material.
[0017] When using the glue application nozzle 10 of this utility model for auxiliary stretching sample preparation, the connecting nozzle 12 of the nozzle 10 is fitted onto the glue outlet tube 11. During the glue dispensing process, the glue flows out from the inlet 14, outlet 15, glue outlet nozzle 13, and glue outlet 17. Since the glue outlet 17 is a long strip or rectangle corresponding to the shape of the mold, the glue dispensing can be wider and can directly fit into the inner groove of the mold, which is convenient and quick and can greatly reduce the defect rate.
[0018] Specifically, the connector 12 is a cylindrical connector 12, and the inlet 14 is a conical inlet 14 that gradually narrows from the outside to the inside.
[0019] Preferably, the dispensing nozzle 13 is a rectangular parallelepiped nozzle 13, and the dispensing outlet 17 is a four-sided pyramidal dispensing outlet 17 that gradually expands in diameter from the inside to the outside.
[0020] Furthermore, such as Figure 3 As shown, the inlet 14 end of the connector 12 is also provided with a connecting ring for connecting with the dispensing tube 11. The dispensing tube 11 is provided with a protrusion 18 protruding from the outer wall of the dispensing tube 11. The connecting ring is provided with an "L"-shaped groove 19 into which the protrusion 18 can be engaged.
[0021] When the dispensing tube 11 is inserted into the nozzle 10, the protrusion 18 is engaged in the vertical groove of the "L"-shaped groove 19. Rotating the nozzle 10 can cause the protrusion 18 to be engaged in the horizontal groove of the "L"-shaped groove 19, preventing the nozzle 10 from falling off the dispensing tube 11.
[0022] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
