[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] The core of this invention is to provide a wide-width spray nozzle to disperse the adhesive, thereby improving the uniformity of the adhesive during spraying and achieving wide-width uniform coating.

[0041] Another core aspect of this invention is to provide a glue spraying device that includes the aforementioned wide-width glue nozzle.

[0042] Another core aspect of this invention is to provide a glue spraying device that includes the aforementioned glue spraying apparatus.

[0043] Please refer to Figure 3 A wide-width glue nozzle includes a glue nozzle body 1, which has a cavity. The glue nozzle body 1 has a glue inlet 101 and a strip-shaped glue outlet 103, both of which are connected to the cavity. The cross-sectional area of ​​the glue outlet 103 is smaller than that of the glue inlet 101. A glue-spreading barrier 102 is provided in the cavity to ensure that the glue entering the cavity through the glue inlet 101 is evenly dispersed.

[0044] It should be noted that uniform dispersion of adhesive in this utility model refers to the adhesive being dispensed evenly from both ends of the strip-shaped nozzle outlet 103, in order to improve the uniformity of adhesive during the spraying process.

[0045] In addition, the cross-sectional area of ​​the hollow cavity in this invention gradually decreases along the downward spacing of the cavity to achieve a smaller spray gap for the strip-shaped glue nozzle outlet 103.

[0046] Optionally, in some embodiments, the nozzle body 1 is integrally molded.

[0047] In other embodiments, the nozzle body 1 is composed of two identical body parts, which are fixed together by bolts or welding. Using bolts makes it easy to disassemble and clear blockages, which is convenient for users.

[0048] In the above embodiments, the contact surfaces of the two body components are connected by a flange structure, or a sealing element 211, such as a sealing gasket or rubber gasket, is provided between the two body components to ensure the sealing performance of the two body components.

[0049] In the above embodiments, there are two identical uniform adhesive resists 102, which are located on the two body parts respectively.

[0050] In use, the glue inlet 101 of the glue nozzle is connected to the glue supply equipment. The glue enters the cavity through the glue inlet 101. The cross-sectional area of ​​the glue outlet 103 of the glue nozzle is smaller than that of the glue inlet 101. At the same time, a glue-spreading device 102 is provided in the cavity. The glue-spreading device 102 is used to evenly disperse the glue that enters the cavity through the glue inlet 101. Therefore, after the glue enters the cavity, the pressure of the glue will increase in the cavity due to the small cross-sectional area of ​​the glue outlet 103. Due to the increased pressure in the cavity, the glue pressure at the glue outlet 103 is not much different. The glue with increased pressure will be evenly sprayed out through the strip-shaped glue outlet, and then dispersed by the glue-spreading device 102, further improving the uniformity of the glue and achieving wide-width uniform coating.

[0051] Please refer to Figure 2 In some embodiments, the cavity includes a uniform dispensing cavity, a shaping cavity, and a dispensing cavity, which are sequentially distributed from the glue inlet 101 to the glue outlet 103. The cross-sectional areas of the uniform dispensing cavity, the shaping cavity, and the dispensing cavity decrease sequentially. That is to say, the cavity is composed of a uniform dispensing cavity, a shaping cavity, and a dispensing cavity. The glue first enters the uniform dispensing cavity and comes into contact with the uniform dispensing resist 102 to achieve uniform dispensing. Then it enters the shaping cavity for shaping and finally is sprayed out through the dispensing cavity and the glue outlet 103 to achieve uniform glue dispensing.

[0052] In the above embodiment, the uniform adhesive cavity and the shaping cavity are separated by the uniform adhesive resist 102.

[0053] In the above embodiments, the cross-sectional areas of the uniform dispensing chamber, the shaping chamber, and the dispensing chamber decrease sequentially, which is beneficial to further increase the pressure at the nozzle outlet and thus increase the uniformity of the dispensing.

[0054] Please refer to Figure 1 In some embodiments, the glue-spreading barrier 102 is a protrusion provided on the glue nozzle body 1. The protrusion is arranged along a preset trajectory, and there are two protrusions, which are symmetrically arranged along the glue outlet 103 of the glue nozzle.

[0055] Optionally, in some embodiments, the protrusion is integrally formed with the nozzle body 1, and the side of the protrusion facing the glue inlet is inclined towards the opposite protrusion to reduce the resistance when the glue flows out, which helps to reduce the generation of air bubbles when the glue is sprayed out.

[0056] In the above embodiment, the provision of two protrusions can further improve the uniformity of glue sprayed from the glue nozzle outlet 103. The two protrusions are respectively provided on both sides of the glue nozzle outlet 103 to improve the uniformity of its distribution.

[0057] In the above embodiment, the centerline of the glue outlet 103 is the centerline along its length.

[0058] Please refer to Figure 1 In some embodiments, the protrusion includes a middle section and two side sections, with the two side sections located on both sides of the middle section. The middle section and the two side sections are arranged in a W-shape. The middle section is arranged parallel to the glue outlet 103 and is located below the glue inlet 101. That is, the protrusion adopts a W-shaped structure, and the middle section is located close to the glue inlet 101, which allows the glue to first contact the middle section when it enters the cavity, so that the middle section exerts a reverse force on the glue, thereby achieving the purpose of dispersing the glue on both sides, which is beneficial to improving the uniformity of the glue.

[0059] Optionally, in some embodiments, the length of the middle section is greater than or equal to the width of the glue inlet 101. Setting the length of the middle section to be longer than the width of the glue inlet 101 can ensure the blocking effect on the glue.

[0060] A glue spraying device includes the aforementioned wide glue spray nozzle.

[0061] Please refer to Figure 4 In some embodiments, a glue supply valve 2 is also included. The glue supply valve 2 includes a valve body 201, which has a glue inlet 202 and a glue outlet 203. The glue nozzle body 1 is installed on the valve body 201, and the glue outlet 203 is connected to the glue inlet 101. The glue supply valve 2 is used to control the opening and closing of the glue outlet 203. That is, the valve body 201 has a cavity, and both the glue inlet 202 and the glue outlet 203 are connected to the cavity. The valve body 201 and the glue nozzle body 1 are detachably connected by bolts, and the glue outlet 203 is connected to the glue inlet 101. The contact surfaces of the glue outlet 203 and the glue inlet 101 are connected by flanges.

[0062] Please refer to Figure 4In some embodiments, the glue supply valve 2 further includes a valve cover 204 and a valve stem 206. The valve cover 204 is installed on the valve body 201. A valve seat 205 is provided at the end of the valve body 201 away from the valve cover 204. The valve stem 206 is installed on the valve cover 204 and located inside the valve body 201. A valve rod 207 is slidably installed inside the valve stem 206. A valve core 208 that cooperates with the valve seat 205 is installed at the end of the valve rod 207. The valve stem 206 is provided with a glue passage cavity 209, which is connected to the glue inlet 202 of the valve body and the glue outlet of the valve body. The glue inlet 203 is connected, meaning that the valve stem 206 is installed on the valve cover 204. The valve cover 204 and the valve body 201 are connected by threads, and their contact surfaces are connected by flanges. A glue passage cavity 209 is provided inside the valve stem 206, and several glue inlet holes are provided on the valve stem 206 to realize the connection between the glue passage cavity 209 and the glue inlet 202 and the glue outlet 203 of the valve body. Therefore, by controlling the movement of the valve core 208, the valve core 208 is separated from or opened from the valve seat 205, thereby realizing the opening or closing of the glue supply valve 2.

[0063] Optionally, in some embodiments, the number of glue inlet holes is at least four, and they are distributed in a circumferential array along the axial direction of the valve stem 206.

[0064] Please refer to Figure 4 In some embodiments, the valve stem 206 is provided with a sealing cavity 210, which is located on the side of the glue passage cavity 209 near the valve cover 204. A sealing element 211 is provided between the sealing cavity 210 and the glue passage cavity 209. The sealing cavity 210 is filled with sealing fluid. In order to improve the sealing performance of the valve stem 207 when sliding, a sealing cavity 210 is provided at the end of the valve stem 206 away from the base, and a sealing element 211 is provided between the sealing cavity 210 and the glue passage cavity 209 to increase the sealing performance of the valve stem 207 when moving. At the same time, the sealing cavity 210 is filled with sealing fluid, which further improves its sealing performance. When glue leakage occurs, the sealing fluid will change color to remind the user of the leakage.

[0065] Optionally, in some embodiments, both the valve body 201 and the valve stem 206 are provided with sealing fluid filling holes for replenishing sealing fluid.

[0066] Optionally, in some embodiments, the sealant filling hole is a threaded hole, and its sealing is achieved by tightening a bolt.

[0067] Optionally, in some embodiments, an observation rod is provided at one end of the bolt inserted into the sealing cavity 210. By inserting the observation rod into the sealing cavity 210, when the sealing liquid changes color, the bolt can be removed to observe the sealing liquid on the observation rod, thus facilitating the observation of the color of the sealing liquid.

[0068] Please refer to Figure 4In some embodiments, the device further includes a drive unit 3, an inlet hose connector 4, and a bracket 5. The drive unit 3 is mounted on the valve cover 204 and is used to control the movement of the valve stem 207. The inlet hose connector 4 is mounted on the valve body 201. The valve body 201 is mounted on the bracket 5. A pipeline fixing assembly 6 is mounted on the bracket 5.

[0069] In the above embodiment, the pipeline fixing assembly 6 includes a fixing plate with a plurality of sockets, and the pipeline fixing assembly 6 is detachably installed on the bracket 5 by bolts.

[0070] In the above embodiments, the valve body 201 and the bracket 5 are detachably connected by bolts, so that each component can be modularized, which facilitates its replacement and maintenance.

[0071] Optionally, in some embodiments, the glue inlet pipe connector 4 includes a glue inlet and a glue outlet, the glue outlet being connected to the glue inlet of the cylinder, and their contact surfaces being connected by a flange.

[0072] A glue spraying device includes the glue spraying apparatus described above.

[0073] In other words, the key point of this utility model is that: the glue enters the cavity through the glue inlet 101, and the cross-sectional area of ​​the glue outlet 103 is smaller than that of the glue inlet 101. At the same time, a glue-spreading device 102 is provided in the cavity. The glue-spreading device 102 is used to evenly disperse the glue entering the cavity through the glue inlet 101. Therefore, after the glue enters the cavity, due to the small cross-sectional area of ​​the glue outlet 103, the glue pressure in the cavity will increase. Because of the increased pressure in the cavity, the glue pressure at the glue outlet 103 is not much different. The glue with increased pressure will be evenly sprayed out through the strip-shaped glue outlet, and then dispersed by the glue-spreading device 102, further improving the uniformity of the glue and achieving wide-width uniform coating.
