[0042] Adhesive needles are connectors widely used in garment factories, washing plants, toy factories, and other fields, primarily for attaching and securing hang tags, labels, and other similar items. Currently, adhesive needles are typically applied using a needle gun, which injects the adhesive onto the product. However, existing needle guns suffer from problems such as needle jamming and low application efficiency.

[0043] Therefore, this utility model proposes a glue needle gun that is less prone to needle jamming and has high injection efficiency. The following is a description of the attached... Figure 1-4 This section describes in detail the glue needle gun of the present invention.

[0044] This utility model embodiment proposes a glue needle gun, such as Figures 1 to 3 As shown, the glue needle gun includes a housing 100, a handle 600, a linkage mechanism 700, a ejector pin mechanism 800, a hook mechanism 900, a syringe 1000, an ejector pin 1100, a hook 1200, a blade 1800, and an oil injection mechanism (not shown). The housing 100 has a first slide 200, a second slide 300, a needle outlet channel 400, and a needle inlet channel 500 inside. The first slide 200 and the second slide 300 are parallel and spaced apart. The needle outlet channel 400 is located at the front end of the first slide 200, and the needle inlet channel 500 is located between the needle outlet channel 400 and the first slide 200. The handle 600 is movably connected to the housing 100, and the linkage mechanism 700 is disposed inside the housing 100 and connects... The lever mechanism 700 is connected to the handle 600; the ejector pin mechanism 800 is located in the first slide 200 and connected to the linkage mechanism 700; the hook needle mechanism 900 is located in the second slide 300 and connected to the linkage mechanism 700; the syringe 1000 is a hollow structure and is located in the needle outlet channel 400; the ejector pin 1100 is connected to the ejector pin mechanism 800; the hook 1200 is connected to the hook needle mechanism 900 and is located below the ejector pin 1100; the blade 1800 is located below the hook 1200; the oil injection mechanism is located outside the housing 100 and is connected to the first slide 200, the second slide 300 and the needle outlet channel 400 through a pipe.

[0045] The glue needle gun according to this utility model embodiment can be used to inject glue needles into products such as socks, clothes, and toys. When the glue needle gun is in operation, the glue needle plate 1700 is first placed in the needle inlet channel 400. The glue needle plate 1700 includes multiple glue needles 1701, and adjacent glue needles 1701 are connected by a connecting strip 1702. At this time, pressing the handle 600 will cause the linkage mechanism 700 to drive the ejector mechanism 800, which in turn pushes the ejector pin 1100, pushing the glue needle 1701 into the syringe 1000, thereby ejecting the glue needle 1701 from the syringe 1000 into the product. Simultaneously, pressing the handle 600 will also drive the hook mechanism 900 through the linkage mechanism 700, causing the hook mechanism 900 to rotate the hook 1200 clockwise. When handle 600 is released, linkage mechanism 700 drives ejector mechanism 800 and ejector pin 1000, simultaneously resetting hook mechanism 900. When hook mechanism 900 resets, it drives hook 1200 to rotate counter-clockwise. At this time, hook 1200 moves the next rubber needle 1701 to the front of ejector pin 1100, facilitating the next press of handle 600 so that ejector pin 1100 can push the next rubber needle 1701. Simultaneously, when hook 1200 moves the next rubber needle 1701 to the front of ejector pin 1100, the connecting strip 1702 of the next rubber needle 1701 is cut by blade 1800. Furthermore, periodically, the oiling mechanism injects machine oil into the first slide rail 200, second slide rail 300, and needle outlet channel 400 through pipes to keep each slide rail unobstructed and prevent needle jamming. The oiling mechanism includes an oil tank containing machine oil and a pump body for pumping out the machine oil.

[0046] Therefore, the glue needle gun according to the present invention is easy to operate, can dispense glue needles 1701 one by one, avoids needle jamming, and improves injection efficiency.

[0047] Furthermore, such as Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the housing 100 includes a base 110 and a top cover 120. A first slide rail 200, a second slide rail 300, and a needle outlet channel 400 are all disposed within the base 110. The top cover 120 is detachably connected to the base 110, and a handle 600 is disposed between the base 110 and the top cover 120. By making the top cover 120 and the base 110 detachably connected, it is convenient to remove the top cover 120 to inspect the various components inside the base 110, facilitating inspection and repair when the glue needle gun malfunctions.

[0048] Furthermore, such as Figure 2As shown, in some embodiments of this utility model, the base 110 is provided with a plurality of positioning holes 111, and the upper cover 120 is provided with a plurality of positioning posts (not shown). The positioning holes 111 correspond one-to-one with the positioning posts, and the base 110 and the upper cover 120 are engaged through the positioning holes 111 and the positioning posts. Simultaneously, to ensure a stable connection between the base 110 and the upper cover 120, screws can be screwed into the positioning posts and positioning holes 111. It should be noted that the base 110 and the upper cover 120 can also be connected by a detachable method such as magnetic attraction.

[0049] Furthermore, such as Figure 2 As shown, in some embodiments of this utility model, the linkage mechanism 700 includes: a first linkage 710, a second linkage 720, an elastic column 730, and a compression spring 740. One end of the first linkage 710 is rotatably connected to the handle 600, and the other end of the first linkage 710 is connected to the pin mechanism 800 and the hook mechanism 900. One end of the second linkage 720 is rotatably connected to one end of the first linkage 710, one end of the elastic column 730 is connected to the other end of the second linkage 720, and the other end of the elastic column 730 is connected to the handle 600. The compression spring 740 is sleeved on the outside of the elastic column 730. When handle 600 is pressed, the first link 710 and the second link 720 will rotate in opposite directions. At this time, the first link 710 can drive the ejector pin mechanism 800 and the hook mechanism 900 to move, while the second link 720 will press the elastic column 730 and the compression spring 740. When handle 600 is released, the elastic column 730 and the compression spring 740 will drive the first link 710 and the second link 720 to reset, so that the first link 710 drives the ejector pin mechanism 800 and the hook mechanism 900 to reset.

[0050] Furthermore, such as Figure 2 As shown, in some embodiments of this utility model, the hook mechanism 900 includes a push block 910 and a connecting needle 920. The push block 910 is disposed within the second slide rail 300 and is connected to the linkage mechanism 700. One end of the connecting needle 920 is connected to the push block 910, and the other end of the connecting needle 920 is rotatably connected to the hook 1200. When the first linkage 710 rotates, it drives the push block 910 to move forward along the second slide rail 300, causing the push block 910 to drive the connecting needle 920 to move forward, and the connecting needle 920 to drive the hook 1200 to rotate clockwise. When the first linkage 710 resets, it drives the push block 910 to reset, causing the connecting needle 920 to drive the hook 1200 to rotate counterclockwise.

[0051] Furthermore, such as Figure 4As shown, in some embodiments of this utility model, the glue gun also includes a protective sleeve 1400, with a connecting wire 1500 connected to the protective sleeve 1400. The housing 100 also has a threading hole, and the connecting wire 1500 is wound around the threading hole. The protective sleeve 1400 is used to cover the syringe 1000. Specifically, when the glue gun is not in use, to prevent damage to the syringe 1000 or damage to the user caused by the syringe 1000, the protective sleeve 1400 is placed over the syringe 1000, which can provide a certain degree of protection. When the glue gun is to be used, the protective sleeve 1400 can be removed, making operation convenient.

[0052] Furthermore, such as Figure 2 As shown, in some embodiments of this utility model, a guide groove 210 is provided at one end of the first slide 200 near the needle outlet channel 400, and the ejector pin 1100 passes through the guide groove 210. The guide groove 210 serves to guide the ejector pin 1100.

[0053] Furthermore, such as Figure 2 As shown, in some embodiments of this utility model, the ejector mechanism 800 includes a top block 810, which is disposed within the first slide rail 200. The top block 810 has an opening groove 820, and the other end of the first connecting rod 710 is placed within the opening groove 820. When the first connecting rod 710 rotates, it can push the top block 810 to move along the first slide rail 200, thereby causing the top block 810 to drive the ejector 1100 to move.

[0054] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
