[0062] The small glue-width atomizing nozzle of the embodiment of the present utility model will be described in detail below with reference to the drawings.

[0063] Refer to Figures 1 to 7 As shown, the small glue-width atomizing nozzle provided by the embodiment of the present utility model includes a housing 10, a glue outlet pipe 20 and a gas supply assembly.

[0064] The housing 10 is used for installing the glue outlet pipe 20. It can be made of stainless steel material, has a long service life, and is beneficial for use. The inside of the glue outlet pipe 20 has a glue outlet hole 21. The glue outlet hole 21 extends in the vertical direction, and the aperture of the lower end of the glue outlet hole 21 is smaller than that of the upper end. In this way, the larger aperture at the upper end of the glue outlet hole 21 can facilitate the entry of water, and the smaller aperture at the lower end of the glue outlet hole 21 can make the glue form a small glue flow. At the same time, the glue flow rate is also relatively fast, so as to facilitate the formation of a small glue path when the glue is sprayed on the product. + A jacket body 22 is arranged at the middle and lower part of the outer wall of the glue outlet pipe 20. The jacket body 22 is tightly connected to the housing 10 to divide the internal space of the housing 10 into an upper space 221 and a lower space 222; A plurality of spiral air outlet grooves 223 communicating the upper space 221 and the lower space 222 are evenly arranged on the jacket body 22. The jacket body 22 protrudes from the outer wall of the glue outlet pipe 20 and is tightly connected to the housing 10, thereby dividing the inside of the housing 10 into an upper space 221 and a lower space 222 that are not connected to each other. The lower end and the glue outlet of the glue outlet pipe 20 are located in the lower space 222. The spiral air outlet grooves 223 are arranged on the jacket body 22. Therefore, the upper space 221 and the lower space 222 can be communicated through the spiral air outlet grooves 223. In this way, the air in the upper space 221 can flow downward through the spiral air outlet grooves 223 and finally be blown to the product together with the glue in the glue outlet pipe 20 from the lower space 222.

[0065] The air supply assembly is connected to the housing 10 and is used for supplying air to the upper space 221 inside the housing 10. The air supply assembly can generate an air flow and transmit the air flow into the upper space 221. The upper space 221 is connected to the lower space 222 through the spiral air outlet grooves 223. Therefore, the air flow can enter the lower space 222 through the spiral air outlet grooves and finally be sprayed out together with the glue in the glue outlet pipe 20, thereby atomizing the glue and making the glue be sprayed on the product more evenly, not prone to splashing or rebounding, and being beneficial to improving the dispensing effect.

[0066] Specifically, when the present application is in use, the air supply assembly can be installed on the dispensing device so as to move along the dispensing path of the product under the drive of the driving mechanism of the dispensing device. During dispensing, the glue is transmitted into the glue outlet pipe 20. Since the aperture of the glue outlet pipe 20 is large at the upper end and small at the lower end, the glue flow is small and the flow rate is fast when the glue is sprayed out through the glue outlet pipe 20. While the glue enters the glue outlet pipe 20, air is introduced into the housing 10 through the air supply assembly. After the air enters the upper space 221 inside the housing 10, it spirally enters the lower space 222 through the spiral air outlet grooves and atomizes the glue when the glue is sprayed out from the glue outlet pipe 20, so that the glue is evenly sprayed on the product. Thus, the phenomenon of glue splashing or rebounding can be avoided, which affects the glue path.

[0067] According to the small glue-width atomizing nozzle provided by the present utility model, the structure is simple and compact, which can be applied to the dispensing of small glue paths. At the same time, the glue can be atomized so that the glue can be evenly sprayed on the product to prevent the glue from splashing.

[0068] Advantageously, in an embodiment of the present utility model, the housing 10 includes an outer shell 11 and a connecting head 12;

[0069] The connecting head 12 is arranged on the lower surface of the bottom wall of the outer shell 11, and a funnel-shaped mounting hole 121 is arranged inside the connecting head 12. The glue outlet pipe 20 passes through the mounting hole 121, and the outer wall of the outer sleeve 22 is tightly connected to the inner wall of the mounting hole 121 to separate the upper space 221 and the lower space 222.

[0070] That is to say, the aperture of the mounting hole 121 inside the connecting head 12 gradually decreases from top to bottom. Then, when the glue outlet pipe 20 is installed in the mounting hole 121, the upper space 221 separated by the outer sleeve 22 is larger than the lower space 222, and in the direction from the upper space 221 to the lower space 222, the space gradually decreases. In this way, it can play a certain role in compressed air, and to a certain extent, it can accelerate the air flow speed, thus being beneficial to improving the atomization efficiency of the glue and being beneficial to use.

[0071] Advantageously, in an embodiment of the present utility model, a connecting seat 111 is arranged inside the outer shell 11. The connecting seat 111 is tightly installed in the mounting hole 121 for installing the glue outlet pipe 20 in the mounting hole 121 and defining the upper space 221 with the outer sleeve 22.

[0072] An installation groove is arranged on the inner surface of the bottom wall of the seat body. The connecting seat 111 is hermetically installed in the installation groove. In this way, the upper space 221 can be formed into a sealed space. Thus, when the air supply component passes the gas into the upper space 221, the gas in the upper air can only quickly flow into the lower space 222 from the spiral air outlet groove to atomize the glue, and cannot be diverted to other spaces, which is beneficial to ensuring the atomization effect.

[0073] Advantageously, in another embodiment of the present utility model, the connecting seat 111 is of a T-shaped structure, and a glue inlet hole 1111 penetrating from the upper surface to the lower surface is arranged on the upper surface;

[0074] The upper end of the glue outlet pipe 20 penetrates into the glue inlet hole 1111, and the glue outlet hole 21 is communicated with the glue inlet hole 1111.

[0075] The glue inlet hole 1111 is generally in a funnel-shaped structure, with its upper end connected to the glue feeding component and its lower end connected to the glue outlet pipe 20. Therefore, it can be used to transfer glue. Its funnel-shaped structure facilitates the introduction of glue and also enables the introduced glue to quickly flow towards the glue outlet pipe 20, thereby enabling the rapid outflow of glue for dispensing.

[0076] Advantageously, in some embodiments of the present invention, the air supply component includes an air pipe connection block 30 and an air supply member;

[0077] The air pipe connection block 30 is in an L-shaped structure, with a through hole 31 provided at its lower end. The outer shell 11 is disposed within the through hole 31, and the lower end of the connection head 12 passes through the through hole 31;

[0078] The air supply member is connected to the air pipe connection block 30 and is used to supply air into the through hole 31 through the air pipe connection block 30.

[0079] Preferably, an air passage 32 is provided within the air pipe connection block 30. The upper airway opening of the air passage 32 is connected to the air supply member, and the lower airway opening is connected to the through hole 31.

[0080] The air pipe connection block 30 is used to connect the outer shell 11 and the air supply member. Specifically, an air passage 32 is provided within the air pipe connection block 30. The upper end of the air passage 32 is connected to the air supply member through an air flow regulating valve. In this way, the air flow rate can be adjusted through the air flow regulating valve. The lower end is connected to the through hole 31 on the air pipe connection block 30. In this way, the gas generated by the air supply member can flow towards the through hole 31 via the air passage 32, and then flow through the through hole 31 into the upper space 221, so as to be blown out from the lower air to atomize the glue subsequently.

[0081] Advantageously, in some other embodiments of the present invention, a first annular groove 112 and a second annular groove 122 are respectively provided on the outer wall of the outer shell 11 and the outer wall of the connection head 12. Sealing rings 1221 are provided within both the first annular groove 112 and the second annular groove 122. The sealing rings 1221 are used to tightly mount the upper ends of the outer shell 11 and the connection head 12 within the through hole 31;

[0082] The lower airway opening of the air passage 32 is located between the first annular groove 112 and the second annular groove 122.

[0083] As a preference, a third annular groove 123 is provided on the outer wall of the connection head 12 above the second annular groove 122. A plurality of air inlet holes 1231 are evenly spaced on the inner wall of the third annular groove 123. The plurality of air inlet holes 1231 are connected to the upper space 221.

[0084] That is to say, a sealing ring 1221 is sleeved on the outer walls of both the outer shell 11 and the connector 12. The sealing ring 1221 is respectively arranged in the first annular groove 112 on the outer wall of the housing 10 and the second annular groove 122 on the outer wall of the connector 12. In this way, a closed space can be formed in the through hole 31 through the sealing washers on the outer shell 11 and the connector 12. This closed space is connected to the lower airway opening of the air passage 32. Therefore, the gas introduced by the gas supply member can flow into this closed space in the through hole 31 after being transmitted through the air passage 32. And a third annular groove 123 is arranged above the second annular groove 122. Therefore, the third annular groove 123 is located in this closed space, and a plurality of air inlet holes 1231 communicating with the upper space 221 are arranged on the third annular groove 123. Then, the air flowing into this closed space can flow into the upper space 221 through the plurality of air inlet holes 1231. In this way, the air can be transmitted into the upper space 221 to facilitate the subsequent atomization of the glue by using the air.

[0085]

[0086] The fourth annular groove 113 below the first annular groove 112 is opposite to the lower airway opening of the air passage 32. Therefore, after the gas enters the fourth annular groove 113 from the lower airway opening of the air passage 32, it can be filled in the fourth annular groove 113. And a plurality of air passing grooves 114 are arranged in the fourth annular groove 113. Therefore, the gas filled in the fourth annular groove 113 can uniformly flow into the third annular groove 123 along the plurality of air passing grooves 114. In this way, by arranging the fourth annular groove 113 and the plurality of air passing grooves 114 therein, a guiding effect can be achieved, ensuring that the gas can uniformly flow into the third annular groove 123 and finally uniformly flow into the upper space 221 through the plurality of air inlet holes 1231. Thus, it can also ensure that the subsequent gas uniformly blows on the glue to atomize the glue.
