Description

Technical Field

[0001] The utility model belongs to the technical field of glue dispensing barrels, and particularly relates to a novel glue dispensing device. Background Art

[0002] For each production process that requires glue dispensing, there is currently a common problem. That is, the shape of the glue ejected from the glue dispensing barrel is circular. When adhering to another part, due to the extrusion between the two parts, the circular glue naturally spreads to both sides. At this time, it is easy to generate bubbles or the phenomenon that the glue on one side is insufficient due to uneven force during extrusion while the glue overflows on the other side.

[0003] For products with relatively strict requirements, sometimes after glue dispensing, it is necessary to use another scraping mechanism to scrape the path of the ejected glue a second time, and then adhere to another product. At this time, the mechanism is large, resulting in waste of equipment. Another problem is the synchronization problem between the two mechanisms. Content of the Utility Model

[0004] To solve the problems raised in the above background art, the utility model provides a novel glue dispensing device, which has the characteristics of completing glue dispensing and scraping at one time.

[0005] To achieve the above object, the utility model provides the following technical solution: A novel glue dispensing device includes a glue dispensing barrel, a glue needle is connected below the glue dispensing barrel, and a glue scraping plate is detachably connected to the circumference of the glue needle.

[0006] To ensure the scraping effect of the glue scraping plate on the glue path, further, the lower end surface of the glue scraping plate is lower than the lower end surface of the glue needle.

[0007] To position and limit the upper end surface of the glue scraping plate and ensure the consistency of the glue outlet height and the scraping height, further, there is a step on the connection surface between the glue dispensing barrel and the glue needle. The glue scraping plate is of a rectangular structure.

[0008] To facilitate the disassembly and assembly between the glue scraping plate and the glue needle, it is convenient to disassemble when the glue scraping plate is not needed, and at the same time, it is also convenient to remove the glue scraping plate for cleaning. Further, an elastic buckle is integrally formed on the side surface of the glue scraping plate.

[0009] To reduce the use cost of the glue scraping plate, further, the glue scraping plate is made of plastic material.

[0010] To adjust the height difference between the lower end surface of the glue scraping plate and the lower end surface of the glue needle, further, a nut is engaged above the glue scraping plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model realizes scraping the glue path while applying glue through the setting of the glue scraping plate, solving the problems of easy generation of bubbles during glue application or uneven force during extrusion, resulting in insufficient glue on one side and glue overflow on the other side. It also solves the problems of large size of the secondary scraping mechanism, which causes equipment waste, and the synchronization problem between the secondary scraping mechanisms.

[0013] 2. The lower end face of the glue scraping plate of the utility model is lower than the lower end face of the glue needle, ensuring the scraping effect of the glue scraping plate on the glue path.

[0014] 3. There is a step on the connection surface between the glue dispensing barrel and the glue needle of the utility model to position and limit the upper end face of the glue scraping plate, ensuring the consistency of the glue outlet height and the scraping height.

[0015] 4. An elastic buckle is integrally formed on the side surface of the glue scraping plate of the utility model, facilitating the disassembly and assembly between the glue scraping plate and the glue needle. It is convenient to disassemble when the glue scraping plate is not needed, and it is also convenient to remove the glue scraping plate for cleaning. Description of the Drawings
