AI Technical Summary
Traditional nozzles have problems such as difficulty in controlling the amount of glue, low glue application efficiency, uneven glue diffusion, unstable connection, and inconvenient cleaning and maintenance in glue application operations.
A novel nozzle structure was designed, comprising a flow guide substrate, a baffle plate, and a temporary adhesive storage space. It is equipped with a flow guide groove and a tapered adhesive supply groove, combined with snap-fit connection and anti-stick coating, to achieve precise control and stable application of adhesive.
It achieves precise control of adhesive dosage, improves the uniformity and efficiency of adhesive application, ensures a stable supply of adhesive and reliable connection, simplifies cleaning and maintenance, and extends service life.

A novel and efficient glue nozzle structure, characterized in that: It includes a flow guide substrate (1), which has an adhesive outlet (2); a baffle plate (3) is provided at the position of the adhesive outlet (2), and the baffle plate (3) and the flow guide substrate (1) enclose an adhesive temporary storage space (4). After the adhesive is discharged from the adhesive outlet (2), it first enters the adhesive temporary storage space (4) and then is applied to the bonding surface through the baffle plate (3).
2. A novel high-efficiency glue nozzle structure according to claim 1, characterized in that: The glue baffle (3) is provided with a guide groove (5) and a glue supply groove (6) connected to the guide groove (5) along the glue supply direction. The glue supply groove (6) is constricted along the glue supply direction.
3. A novel and efficient glue nozzle structure as claimed in claim 2, wherein: The number of the guide grooves (5) is set to multiple, and all the guide grooves (5) are connected to the glue supply groove (6); the distance between the outer edges of the two guide grooves (5) that are furthest apart is less than or equal to the initial width of the glue supply groove (6).
4. The novel and efficient glue nozzle structure according to claim 2, characterized in that: The end of the guide channel (5) near the glue supply channel (6) has a trapezoidal opening (7), and the opening width is adapted to the initial width of the glue supply channel (6).
5. A novel and efficient glue nozzle structure as claimed in claim 4, wherein: The width of the closed end of the glue supply groove (6) is 1 / 3 to 1 / 2 of the initial width.
6. A novel and efficient glue nozzle structure as claimed in claim 1, wherein: The other end of the flow guide substrate (1) is provided with a cylindrical mounting part (8) for connecting the glue supply device, and the outer diameter of the cylindrical mounting part (8) is adapted to the inner diameter of the interface of the glue supply device.
7. A novel and efficient glue nozzle structure as claimed in claim 6, wherein: The flow guide base (1) is semi-cylindrical, and a flow guide structure is provided between the cylindrical mounting part (8) and the flow guide base (1). The flow guide structure is a flow guide part (9) that smoothly transitions from cylindrical to semi-cylindrical.
8. A novel and efficient glue nozzle structure as claimed in claim 1, wherein: The adhesive baffle (3) is provided with a baffle (11) for allowing the adhesive to flow in one direction. The baffle (11) extends along the adhesive supply direction.
9. A novel and efficient glue nozzle structure as claimed in claim 1, wherein: The flow guide substrate (1) and the baffle plate (3) are detachably connected by a snap-fit structure, or are integrally molded by injection molding.
10. A novel and efficient glue nozzle structure as claimed in claim 1, wherein: The surface of the baffle plate (3) in contact with the adhesive is provided with an anti-stick coating (12), the anti-stick coating (12) is made of polytetrafluoroethylene and the coating thickness is 0.1-0.3mm.
