Description

Technical Field

[0001] This utility model belongs to the field of glass production technology. Specifically, this utility model relates to a glue nozzle for applying adhesive to insulated glass. Background Technology

[0002] Currently, manual production lines for insulating glass coating products cannot complete the coating process in one go. The traditional production method involves applying structural adhesive to the glass surface according to the required coating width, and then using a scraper to smooth it from beginning to end. This process is time-consuming, labor-intensive, inefficient, and results in discontinuous production. The coated surface is not glossy and is prone to air bubbles, which seriously affects the appearance quality and safety of the finished insulating glass and can also cause adhesive overflow, resulting in contamination of the glass surface.

[0003] Chinese patent application CN109158268A, published on January 8, 2019, discloses a rotating glass coating rack for producing insulated glass. The rack includes a frame, a glass receiving frame rotatable relative to the frame, a glass placement position on the glass receiving frame, a sliding guide rail located on the side of the frame, a slider slidable relative to the sliding guide rail, a coating arm hinged to the slider, and a coating head located at the end of the coating arm and coupled to the coating arm. The rotation axis of the glass receiving frame is perpendicular to the extension direction of the sliding guide rail. However, this rotating glass coating rack does not solve the aforementioned technical problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a simple, easy-to-operate, and efficient adhesive nozzle for applying adhesive to insulating glass.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The adhesive nozzle for applying adhesive to insulating glass includes an interface, which is connected to an adhesive dispensing head. The adhesive dispensing head includes an adhesive dispensing channel, and a positioning baffle is provided on one side of the adhesive dispensing head.

[0007] A partition is fixedly connected to one side of the interface, and a through hole is provided in the middle of the partition, which is connected to the glue outlet channel.

[0008] The dispensing head is inclined relative to the lower end face of the positioning baffle; the lower end face of the dispensing head is parallel to the lower end face of the positioning baffle.

[0009] Both the dispensing head and the dispensing channel have rectangular cross-sections.

[0010] The interface cross-section is a circular ring structure.

[0011] The partition has positioning notches on both sides.

[0012] The interface end is provided with a bevel.

[0013] The dispensing head and the positioning baffle are an integral structure, and the interface, dispensing head and partition are fixed by welding.

[0014] The technical advantages of this invention are as follows: The adhesive nozzle for insulating glass coating of this invention changes the traditional coating method, eliminating the time required for smoothing the structural adhesive with an oil-spraying knife. It achieves one-time injection and smoothing, avoiding excess sealant overflow and waste. The positioning baffle on the side of the nozzle makes positioning more convenient and faster, reducing manual steps, lowering sealant usage costs, and better ensuring product appearance and performance. No other auxiliary tools are required during operation; the one-time injection and coating process helps reduce manpower, improve per capita production efficiency, increase the overall production line output, and achieve the goals of product quality and mass production processing.

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.

[0022] like Figures 1 to 4As shown, the sealing nozzle for insulated glass includes an interface 1 connected to a dispensing head 2. The dispensing head 2 includes a dispensing channel 5 and a positioning baffle 4 on one side. The interface 1 is snapped into place with the outlet end of the glue gun for easy installation. The dispensing channel 5 is used to shape the sealant, ensuring uniform dispensing and forming the required coating width. The dispensing head 2 smooths the sealant layer. During the application process, the positioning baffle 4 holds the glass edge, positioning the sealant and ensuring that the position of the dispensing head 2 in the dispensing channel 5 remains constant relative to the glass. This controls the uniformity of the coating surface, and because the positioning baffle 4 holds the glass edge, the sealant will not overflow from the glass edge, ensuring the product's appearance.

[0023] like Figure 1 As shown, a partition 3 is fixedly connected to one side of interface 1. A through hole 6 is provided in the middle of the partition 3, which communicates with the glue dispensing channel 5. After interface 1 is engaged with the glue gun, the partition 3 can abut against the outlet end of the glue gun, so that the glue gun is installed in place and the sealant will not overflow from the gap between interface 1 and the glue gun when the glue gun dispenses glue.

[0024] like Figure 2 As shown, the dispensing head 2 is inclined relative to the lower end face of the positioning baffle 4; the lower end face of the dispensing head 2 is parallel to the lower end face of the positioning baffle 4. This structure allows the glue gun to dispense glue at an angle to the glass, which facilitates the smoothing of the glue layer by the dispensing head 2 and increases the glue output. During operation, there is no obstruction to the view of the glue layer, making it easier for the operator to observe and control. With this structure, during the glue application process, when the lower end face of the dispensing head 2 abuts against the glass, the lower end face of the positioning baffle 4 abuts against the worktable surface, also achieving a positioning effect. This, combined with the side of the positioning baffle 4, forms two positioning points, further improving the positioning accuracy of the dispensing head 2 and the ease of operation.

[0025] like Figure 2 As shown, both the dispensing head 2 and the dispensing channel 5 have rectangular cross-sections. The above-described structure of the dispensing head 2 and dispensing channel 5 facilitates the formation of the required adhesive width, prevents sealant overflow, and ensures that the length of the through-hole 6 matches the dispensing channel 5, guaranteeing smooth sealant dispensing without residue.

[0026] like Figure 1 As shown, the cross-section of interface 1 is a circular ring structure. Interface 1 has a cylindrical structure, which has good versatility and can adapt to the shape of various glue guns.

[0027] like Figure 3 As shown, positioning notches 7 are provided on both sides of the partition 3. The width of the positioning notches 7 is the same as the thickness of the dispensing head 2, which facilitates accurate matching between the through hole 6 and the dispensing channel 5.

[0028] like Figure 1 As shown, the end of interface 1 is provided with a bevel angle 8. The bevel angle 8 serves to guide the installation of interface 1 and the outlet end of the glue gun, preventing excessive contact force between the two from causing damage.

[0029] like Figure 1 and Figure 2 As shown, the dispensing head 2 and the positioning baffle 4 are an integral structure, and the interface 1, dispensing head 2, and baffle 3 are fixed by welding. Both the dispensing head 2 and the positioning baffle 4 are structures that contact the glass, and their integral structure makes them less prone to deformation and damage. The interface 1, dispensing head 2, and baffle 3 can be molded separately to accommodate different sizes of glue guns and different glue application widths. The three are welded together to form an integral structure, making them less prone to damage.

[0030] The adhesive nozzle for insulating glass is made with a duckbill-shaped dispensing head 2 of a matching width according to the adhesive width requirements of insulating glass processing. The dispensing head 2 is embedded in a pneumatic or manual glue gun to achieve one-time dispensing, smoothing and forming of adhesive. The adhesive effect is full and glossy, without overflow, without bubbles, and without residual adhesive, ensuring product performance and improving the quality and appearance of the finished product.

[0031] The operating method is as follows: Secure interface 1 to the glue gun, ensuring that the partition 3 abuts against the glue gun outlet end so that its through-hole 6 aligns with it. Place the positioning baffle 4 against the glass edge, controlling the glue gun to move the dispensing head 2 along the glass edge. Complete the glue application process around the glass in sequence, then proceed with subsequent work. During the glue application process, the rectangular dispensing channel 5 forms a uniform glue layer. The dispensing head 2 at the rectangular outlet end provides a uniform smoothing effect on the glue layer, reducing scraping time during production and improving production efficiency. The positioning baffle 4 positions the dispensing head 2, reducing waste caused by glue extrusion and maximizing the saving of hollow glue and consumption costs, thus achieving the goal of reducing glue consumption and saving costs.

[0032] This insulated glass adhesive applicator has revolutionized traditional adhesive application methods, eliminating the need for a spatula to smooth the structural adhesive. It achieves a one-step application and smoothing process, preventing excess sealant overflow and waste. The applicator head features a positioning baffle plate on its side for easier and faster positioning, reducing manual steps, lowering sealant usage costs, and better ensuring product appearance and performance. No other auxiliary tools are required during operation; the one-step application reduces manpower, increases per capita productivity, and improves the overall production line output, achieving the goals of product quality and mass production.

[0033] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
