Description

Technical Field

[0001] This utility model relates to the field of glue dispensing machine technology, and more specifically, to a glue dispensing nozzle for a semi-automatic glue dispensing machine. Background Technology

[0002] Traditional glue dispensing nozzles consist of a metal tube. One end of the nozzle is fixedly connected to the glue dispensing machine, and an empty tube is fitted over the other end. The glue from the dispensing machine flows from the nozzle into the tube. After dispensing, the empty tube is usually fitted over the nozzle to protect it. This serves two purposes: preventing foreign objects from entering the nozzle and reducing air intake, thus extending the curing time of any remaining glue. However, in practical use, this protection only lasts for a short time. Therefore, improvements to traditional glue dispensing nozzles are necessary. Utility Model Content

[0003] The purpose of this utility model is to provide a dispensing nozzle for a semi-automatic dispensing machine that solves the above-mentioned problem.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A dispensing nozzle for a semi-automatic dispensing machine includes a dispensing nozzle body for connection with the dispensing machine. The dispensing nozzle body includes an outer tube and an inner tube. The inner tube is connected to the outer tube in a frictionless seal. The outlet end of the inner tube is threadedly connected to the outer tube.

[0006] Preferably, the outlet end of the inner tube protrudes to the outside of the outer tube, and a connecting pipe head is integrally provided at this end. The outer diameter of the connecting pipe head is equal to the outer diameter of the outer tube, and the connecting pipe head is threadedly connected to the outer tube.

[0007] Preferably, the outer circumferential surface of the outlet end of the outer tube is provided with an external thread, and the end of the connecting pipe head opposite the outer tube is provided with a nut, and the nut is provided with an internal thread for engaging with the external thread.

[0008] Preferably, the outer tube has an internal thread on its inner circumferential surface at the outlet end, and the connecting tube head has an inner bushing protruding at one end opposite to the outer tube. The inner bushing has an external thread for engaging with the internal thread.

[0009] Preferably, a retaining ring is integrally provided on the inner circumference of the other end of the outer tube opposite to the connecting pipe head, and the inner diameter of the retaining ring is equal to the inner diameter of the inner tube.

[0010] Preferably, it also includes a cap, which is used to provide a threaded seal connection with the outlet end of the outer tube when the inner tube is pulled out from the outer tube.

[0011] Preferably, a suspension rope is connected to the cap, and the other end of the suspension rope is connected to the outer tube.

[0012] The beneficial effects of this utility model are: during the glue dispensing operation, the inner tube is disassembled into the outer tube, and the glue flows from the inner tube into the inner tube. After the glue dispensing operation is completed, the inner tube is pulled out from the outer tube, which makes it easy to clean the glue residue in the inner tube and keep the inner tube clean. At the same time, the cap is threadedly connected to the outer tube to prevent foreign objects from entering the outer tube. Attached Figure Description

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0020] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0021] according to Figure 1-4As shown, a dispensing nozzle for a semi-automatic dispensing machine includes a dispensing nozzle body for connection with the dispensing machine. The dispensing nozzle body includes an outer tube 1 and an inner tube 2. The inner tube 2 is connected to the outer tube 1 in a frictionless seal. The outlet end of the inner tube 2 protrudes to the outside of the outer tube 1, and a connecting tube head 21 is integrally provided at this end. The outer diameter of the connecting tube head 21 is equal to the outer diameter of the outer tube 1. The connecting tube head 21 is threadedly connected to the outer tube 1. The other end of the outer tube 1, opposite the outlet end, is welded or threadedly connected to the dispensing machine body. A sealing cap 3 is connected to the outer tube 1 near the connecting tube head 21 by a hanging rope 4. When the inner tube 2 is pulled out from the outer tube 1, the sealing cap 3 is used to make a threaded seal connection with the outlet end of the outer tube 1.

[0022] There are two ways to connect the connecting pipe head 21 to the outer pipe 1. One way is that the outer circumference of the outlet end of the outer pipe 1 is provided with an external thread, and the connecting pipe head 21 is provided with a nut protruding from one end opposite the outer pipe 1. The nut is provided with an internal thread for mating with the external thread (e.g., ...). Figure 1 (as shown); another type has an internal thread on the inner circumference of the outlet end of the outer tube 1, and an inner bushing protrudes from one end of the connecting tube head 21 relative to the outer tube 1. The inner bushing has an external thread for engaging with the internal thread.

[0023] according to Figure 3-4 As shown, a retaining ring 11 is integrally formed on the inner circumference of the other end of the outer tube 1 relative to the connecting tube head 21. The inner diameter of the retaining ring 11 is equal to the inner diameter of the inner tube 2. The retaining ring 11 is set to protect the inner tube 2 and prevent the glue from impacting the inner tube 2 or even flowing between the inner tube 2 and the outer tube 1 during glue pouring. A hanging rope 4 is connected to the cap 3, and the other end of the hanging rope 4 is connected to the outer tube 1.

[0024] according to Figure 1-4 As shown, during the glue dispensing operation, the inner tube 2 is inserted into the outer tube 1, and the glue flows from the inner tube 2 into the inner tube 2. After the glue dispensing operation is completed, the inner tube 2 is pulled out from the outer tube 1 to facilitate cleaning of the glue residue in the inner tube 2 and to keep the inner tube 2 clean. At the same time, the cap 3 is threadedly connected to the outer tube 1 to prevent foreign objects from entering the outer tube 1.
