Description

Technical Field

[0001] The utility model relates to the technical field of building decoration equipment, and particularly to a glue nozzle for a glue gun. Background Art

[0002] Glass curtain walls for building decoration usually require gluing, which means using a glue gun to apply glue for sealing, bonding or filling. Traditional gluing usually adopts a working mode where one person injects glue and the other person scrapes glue. It requires two steps and two people to cooperate with each other, resulting in high labor costs and low gluing efficiency.

[0003] The glue injection workers use glue guns to inject two-component structural glue into the groove between the curtain wall and the frame, and then the glue scraping workers use scrapers to scrape the glue. The scraper tool and the proficiency of the glue scraping workers are related to the quality of the glue. Usually, the glue is not formed after one scraping, and it has to be scraped repeatedly for two or three times. The amount of glue cannot be effectively controlled, resulting in waste of materials.

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-3 The utility model is described in further detail.

[0024] like Figure 1 As shown, a glue nozzle for a glue gun includes a steering assembly 1 and a glue injector 2 which are sequentially connected to a glue outlet pipe 4 of the glue gun. The glue injector 2 includes a glue feed cylinder 21 and a scraper 22. A glue outlet 221 is provided at the front end of the bottom surface of the scraper 22. A guide cavity 23 for the colloid to pass through is provided in the scraper 22. The inlet of the guide cavity 23 is connected to the glue feed cylinder 21, and the outlet of the guide cavity 23 is connected to the glue outlet 221. The other end of the glue feed cylinder 21 is detachably connected to the steering assembly 1.

[0025] The scraper 22 of this embodiment is a rectangular flat body made of stainless steel. The flat scraper 22 is convenient for scraping the concave gap between the curtain wall and the frame.

[0026] The glue outlet 221 of this embodiment is a waist-shaped hole, and the glue outlet 221 is parallel to the front edge of the scraper 22 .

[0027] like Figure 1 As shown, the guide cavity 23 of this embodiment extends along the axial direction of the rubber inlet cylinder 21, and the guide cavity 23 is in a trapezoidal shape from the inlet of the guide cavity 23 to the outlet of the guide cavity 23 with a larger rear portion and a smaller front portion.

[0028] The guide cavity 23 is a trapezoidal shape that gradually shrinks from the rear side of the scraper 22 to the front, which can play a role in colloid flow transition and reduce the flow speed of the glue. When the viscosity of the colloid is large, it can reduce the flow resistance of the colloid and improve the uniformity of the glue out of the glue outlet 221.

[0029] In this embodiment, a buffer groove 231 is provided in the guide cavity 23 near the glue outlet 221 , and is recessed into the inner wall of the guide cavity 23 . The buffer groove 231 is parallel to the glue outlet 221 .

[0030] The colloid entering from the inlet of the guide cavity 23 first fills the buffer groove 231 , and then the colloid in the buffer groove 231 overflows and flows to the glue outlet 221 to overflow outward, thus ensuring that the thickness of the colloid flowing out from the glue outlet 221 is uniform.

[0031] like Figure 1 As shown, both ends of the buffer groove 231 of this embodiment extend to both sides of the guide cavity 23 .

[0032] like Figure 2 , 3 As shown, the flow guiding cavity 23 has two buffer grooves 231 .

[0033] Figure 2 It is a schematic diagram of the structure of two buffer slots 231 arranged opposite to each other. Figure 3 The schematic diagram is a structural diagram of two buffer grooves 231 arranged alternately. The cross section of the buffer groove 231 is a trapezoidal groove or a semicircular groove. By providing the buffer groove 231, the colloid first fills the buffer groove 231 after entering the guide cavity 23, and then flows from the buffer groove 231 to the glue outlet 221, ensuring that the colloid flowing out of the glue outlet 221 can flow evenly to the bottom surface of the scraper 22.

[0034] like Figure 1 , 2 As shown, the glue inlet tube 21 includes a tubular joint 211 and a duckbill tube 212. The inner wall of the joint 211 is provided with an internal thread. The joint 211 is threadedly connected to the flexible joint 14. The duckbill tube 212 is in a duckbill shape. The round mouth of the duckbill tube 212 is fixedly connected to the joint 211, and the flat mouth of the duckbill tube 212 is connected to the inlet of the guide chamber 23. By setting the duckbill tube 212, the glue inlet tube 21 is transitioned from a cylindrical shape to a flat mouth to adapt to the inlet of the guide chamber 23, thereby ensuring that the colloid enters the guide chamber 23 smoothly.

[0035] The steering assembly 1 includes an L-shaped joint 11, a first joint 12, a universal joint 13 and a second joint 14 which are threadedly connected in sequence. The other end of the L-shaped joint 11 is threadedly connected to the glue outlet pipe 4 of the glue gun, and the other end of the second joint 14 is threadedly connected to the joint 211 on the glue inlet cylinder 21; the universal joint 13 allows the colloid to pass through and can rotate 360° horizontally and rotate up and down at a certain angle. By setting the universal joint 13, the angle adjustment of the glue injector 2 is facilitated to adapt to the injection and scraping of glue in the gap between the glass curtain wall and the frame, and at the same time it can adapt to the height of the operator.

[0036] like Figure 1-3 As shown, in order to prevent the colloid squeezed out from the glue outlet 221 from flowing to the outside of the scraper 22 by weight, a glue blocking strip 3 protruding from the bottom surface of the scraper 22 is provided at the front edge of the scraper 22, and the length of the glue blocking strip 3 is slightly greater than the length of the glue outlet 221.

[0037] Since the glue nozzle adopts the synchronous operation of glue injection and glue scraping, the glue consumption during glue injection is effectively reduced, thereby reducing the production cost.

[0038] When the glue nozzle is in use, the L-shaped joint 11 is threadedly connected to the glue outlet pipe 4 of the glue gun, and the flexible joint 12, the universal joint 13, the flexible joint 214 and the joint 211 on the glue inlet cylinder 21 are threadedly connected in sequence; when the glue injection starts, the glue outlet 221 is aligned with the concave gap between the curtain wall and the frame along the length direction, and the glue is squeezed out from the glue outlet 221 to fill the concave gap, while the scraper 22 is moved along the length direction of the concave gap between the curtain wall and the frame. In the process of moving the scraper 22, the excess glue is scraped and taken away by the scraper 22, and can also be used to fill the gap with less glue filling. Through the rapid scraping of the scraper 22, the surface of the concave gap filled with glue is smooth and flat, which improves the aesthetics of the glue application, overcomes the two processes of glue injection and glue scraping in the prior art, solves the defects of uneven glue scraping and more glue waste, and glue injection and glue scraping are completed simultaneously, thereby improving work efficiency, saving glue consumption, reducing resource waste, and reducing production costs.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
