Description

Technical Field

[0001] This utility model relates to the field of dispensing technology, specifically to an extended nozzle used in dispensing processes. Background Technology

[0002] Dispensing is a process, also known as gluing, coating, or dripping, in which a certain amount of adhesive is applied to the surface or interior of a product using specialized equipment to achieve functions such as bonding, potting, insulation, fixing, and heat dissipation. Dispensing technology is widely used in many fields, including electronics, automobiles, and construction, and has multiple functions and importance.

[0003] However, when using existing dispensing nozzles, the specifications of the nozzles are fixed, and most of them are short. However, when the dispensing position is narrow or deep, the nozzle is restricted by the dispensing valve and cannot directly reach the dispensing area, which affects the dispensing range and accuracy. Therefore, an extended nozzle for dispensing is designed. Utility Model Content

[0004] The main purpose of this invention is to provide an extended nozzle for dispensing. This invention solves the problem that existing dispensing nozzles are inconvenient to adjust the position of the inner nozzle during use, and cannot dispense glue to narrower or deeper areas, by setting an adjustment component, an outer nozzle, an inner nozzle, and a nozzle hole.

[0005] The technical solution adopted by this utility model to solve its technical problem is an extended nozzle applied to dispensing processing, including an outer nozzle and an inner nozzle. An adjustment component for fixing the inner nozzle is provided on the outside of the outer nozzle. The adjustment component includes an arc plate A, an arc plate B, a limiting block A, a limiting block B, and a threaded sleeve. The arc plate A is rotatably connected to the outside of the outer nozzle, and the end of the arc plate A away from the outer nozzle is welded with the limiting block A. The arc plate B is rotatably connected to one side of the outer nozzle, and the limiting block B is welded to one end of the arc plate B to contact the inner nozzle. The limiting blocks A and B are threadedly connected to the outside of the threaded sleeve to tightly connect the limiting blocks A and B with the inner nozzle.

[0006] By adopting the above technical solution, when adjusting the nozzle, the threaded sleeve outside the limiting blocks A and B is rotated, causing the threaded sleeve to separate from the limiting blocks A and B. Then, the arc plate A on the outer nozzle drives the limiting block A to rotate, and the arc plate B drives the limiting block B to rotate, causing the limiting blocks A and B to separate from the surface of the inner nozzle. Then, the inner nozzle is pulled to move on the outer nozzle. After the position of the inner nozzle is adjusted, the arc plate A drives the limiting block A to rotate, and the arc plate B drives the limiting block B to rotate, causing the limiting blocks A and B to contact the surface of the inner nozzle. Then, the threaded sleeve is moved through the inner nozzle to the end of the limiting blocks A and B. Then, the threaded sleeve is rotated to move the threaded sleeve outside the limiting blocks A and B, so that the limiting blocks A and B are in close contact with the surface of the inner nozzle, fixing the inner nozzle. This facilitates the adjustment of the position of the inner nozzle and improves the range and accuracy of glue application.

[0007] Specifically, the inner nozzle has a nozzle hole at the end away from the outer nozzle to allow glue to be discharged.

[0008] By adopting the above technical solution, when the glue enters the inner nozzle through the outer nozzle, the nozzle hole at the end of the inner nozzle discharges the glue, thus facilitating the glue application operation.

[0009] Specifically, a rubber ring is bonded to the end of the inner nozzle away from the nozzle orifice to increase the sealing with the outer nozzle.

[0010] By adopting the above technical solution, a rubber ring is bonded to the outer end of the inner nozzle that enters the outer nozzle. The rubber ring contacts the inner side of the outer nozzle, thereby improving the sealing between the outer nozzle and the inner nozzle.

[0011] Specifically, rubber pads that increase the friction on the surface of the inner nozzle are adhered to the inner sides of both the limiting block A and the limiting block B.

[0012] By adopting the above technical solution, when the inner sides of the limiting blocks A and B contact the surface of the inner nozzle, the rubber pads bonded inside the limiting blocks A and B increase the friction on the surface of the inner nozzle, thereby improving the stability of the limiting blocks A and B in clamping the inner nozzle.

[0013] Specifically, the threaded sleeve is provided with protrusions on its exterior to increase the friction of the threaded sleeve surface.

[0014] By adopting the above technical solution, the protrusions on the outside of the threaded sleeve increase the friction on the outside of the threaded sleeve, making it easier for the threaded sleeve to rotate.

[0015] The beneficial effects of this utility model are:

[0016] This utility model describes an extended nozzle for dispensing applications. When dispensing glue to narrower or deeper areas, the threaded sleeves outside the limiting blocks A and B are rotated, causing them to separate from the limiting blocks A and B. Then, the arc plate A on the outer nozzle drives the limiting block A to rotate, and the arc plate B drives the limiting block B to rotate, causing the limiting blocks A and B to separate from the surface of the inner nozzle. The inner nozzle is then pulled along the outer nozzle. After the inner nozzle position is adjusted, the arc plate A drives the limiting block A to rotate, and the arc plate B drives the limiting block B to rotate, causing the limiting blocks A and B to contact the surface of the inner nozzle. The threaded sleeve is then moved through the inner nozzle to the ends of the limiting blocks A and B. The threaded sleeve is then rotated to move outside the limiting blocks A and B, causing the limiting blocks A and B to make tight contact with the surface of the inner nozzle, thus fixing the inner nozzle. This facilitates the adjustment of the inner nozzle's position, improving the dispensing range and accuracy. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] In order to adjust the position of the inner nozzle 3, as an embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 3As shown, the extended nozzle for dispensing according to this utility model includes an outer nozzle 1 and an inner nozzle 3. An adjustment component 2 for fixing the inner nozzle 3 is provided on the outside of the outer nozzle 1. The adjustment component 2 includes an arc plate A6, an arc plate B8, a limiting block A7, a limiting block B9, and a threaded sleeve 12. The arc plate A6 is rotatably connected to the outside of the outer nozzle 1, and the limiting block A7 is welded to the end of the arc plate A6 away from the outer nozzle 1. The arc plate B8 is rotatably connected to one side of the outer nozzle 1, and the limiting block B9, which contacts the inner nozzle 3, is welded to one end of the arc plate B8. The limiting blocks A7 and B9 are threadedly connected to the inner nozzle 3 by the threaded sleeve 12, which tightly connects the limiting blocks A7 and B9 with the inner nozzle 3.

[0024] During use, when applying glue to narrower or deeper areas, rotate the threaded sleeve 12 outside the limiting blocks A7 and B9, causing the threaded sleeve 12 to separate from the limiting blocks A7 and B9. Then, the arc plate A6 on the outer nozzle 1 drives the limiting block A7 to rotate, and the arc plate B8 drives the limiting block B9 to rotate, causing the limiting blocks A7 and B9 to separate from the surface of the inner nozzle 3. Then, pull the inner nozzle 3 to move on the outer nozzle 1. After the position of the inner nozzle 3 is adjusted, the arc plate A6 drives the limiting block A7 to rotate. The arc plate B8 drives the limiting block B9 to rotate, so that the limiting blocks A7 and B9 come into contact with the surface of the inner nozzle 3. Then, the threaded sleeve 12 passes through the inner nozzle 3 and moves to the end of the limiting blocks A7 and B9. Then, the threaded sleeve 12 is rotated so that it moves outside the limiting blocks A7 and B9, so that the limiting blocks A7 and B9 are in close contact with the surface of the inner nozzle 3, fixing the inner nozzle 3. This makes it easier to adjust the position of the inner nozzle 3 and improves the range and accuracy of glue application.

[0025] For example, to perform the glue application operation, such as... Figure 1 , Figure 2 and Figure 3 As shown, the present invention also includes a nozzle hole 4 for discharging glue at the end of the inner nozzle 3 away from the outer nozzle 1.

[0026] When in use, when the glue enters the inner nozzle 3 through the outer nozzle 1, the nozzle hole 4 at the end of the inner nozzle 3 discharges the glue, thus facilitating the glue application operation.

[0027] To improve the sealing between the outer nozzle 1 and the inner nozzle 3, for example, such as... Figure 2 As shown, the present invention also includes a rubber ring 5 that is bonded to the end of the inner nozzle 3 away from the nozzle hole 4 to increase the sealing with the outer nozzle 1.

[0028] During use, a rubber ring 5 is bonded to the outer end of the inner nozzle 3 that enters the outer nozzle 1. The rubber ring 5 contacts the inner side of the outer nozzle 1, thereby improving the sealing between the outer nozzle 1 and the inner nozzle 3.

[0029] To improve the stability of the clamping of the inner nozzle 3 by the limiting block A7 and the limiting block B9, for example, as follows: Figure 3 As shown, this utility model also includes rubber pads 10 that increase the friction on the surface of the inner nozzle 3, which are both bonded to the inner sides of the limiting block A7 and the limiting block B9.

[0030] When in use, when the inner sides of the limiting blocks A7 and B9 contact the surface of the inner nozzle 3, the rubber pads 10 bonded inside the limiting blocks A7 and B9 increase the friction on the surface of the inner nozzle 3, thereby improving the stability of the limiting blocks A7 and B9 in clamping the inner nozzle 3.

[0031] To facilitate the rotation of the threaded sleeve 12, for example, as shown... Figure 3 As shown, the present invention also includes protrusions 11 on the outside of the threaded sleeve 12 to increase the surface friction of the threaded sleeve 12.

[0032] During use, the protrusions 11 on the outside of the threaded sleeve 12 increase the friction on the outside of the threaded sleeve 12, making it easier for the threaded sleeve 12 to rotate.

[0033] In use, the outer nozzle 1 is first connected to the glue cartridge. Glue then enters the outer nozzle 1 and is transferred to the inner nozzle 3. The glue then exits through the nozzle hole 4 on the inner nozzle 3, facilitating glue application. When applying glue to narrower or deeper areas, the threaded sleeve 12 outside the limiting blocks A7 and B9 is rotated, causing the threaded sleeve 12 to separate from the limiting blocks A7 and B9. Then, the arc plate A6 on the outer nozzle 1 drives the limiting block A7 to rotate, and the arc plate B8 drives the limiting block B9 to rotate, causing the limiting blocks A7 and B9 to separate from the surface of the inner nozzle 3. Finally, the inner nozzle 3 is pulled... After the inner nozzle 3 is adjusted, the outer nozzle 1 moves and the inner nozzle 3 is moved. Then, the arc plate A6 drives the limiting block A7 to rotate, and the arc plate B8 drives the limiting block B9 to rotate, so that the limiting blocks A7 and B9 contact the surface of the inner nozzle 3. Then, the threaded sleeve 12 passes through the inner nozzle 3 and moves to the end of the limiting blocks A7 and B9. Then, the threaded sleeve 12 is rotated so that the threaded sleeve 12 moves to the outside of the limiting blocks A7 and B9, so that the limiting blocks A7 and B9 are in close contact with the surface of the inner nozzle 3, thus fixing the inner nozzle 3. This makes it easier to adjust the position of the inner nozzle 3 and improves the range and accuracy of glue application.

[0034] When the glue enters the inner nozzle 3 through the outer nozzle 1, the nozzle hole 4 at the end of the inner nozzle 3 discharges the glue, thus facilitating the glue application operation.

[0035] A rubber ring 5 is bonded to the outer end of the inner nozzle 3 that enters the outer nozzle 1. The rubber ring 5 contacts the inner side of the outer nozzle 1, thereby improving the sealing between the outer nozzle 1 and the inner nozzle 3.

[0036] When the inner sides of the limiting blocks A7 and B9 come into contact with the surface of the inner nozzle 3, the rubber pads 10 bonded inside the limiting blocks A7 and B9 increase the friction on the surface of the inner nozzle 3, thereby improving the stability of the limiting blocks A7 and B9 in clamping the inner nozzle 3.

[0037] The protrusions 11 provided on the outside of the threaded sleeve 12 increase the friction on the outside of the threaded sleeve 12, making it easier for the threaded sleeve 12 to rotate.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
