Description

Technical Field

[0001] The utility model relates to the technical field of glue spray nozzles, in particular to a glue spray nozzle with flexible angle adjustment. Background Art

[0002] Glue is a viscous liquid substance, which is usually formed by dissolving or dispersing high molecular polymers or other viscous components in a solvent. In industrial production, such as the manufacture of adhesive products and coating processes, glue spray nozzles play a key role in accurately controlling the distribution and amount of glue. By adjusting the parameters of the nozzle, such as the aperture size and angle, different glue spraying effects can be achieved, such as atomization effect, linear spraying, etc.

[0003] The glue spray nozzle usually has a small outlet that can spray the glue evenly in a specific form and flow rate. The glue spray nozzle can be designed into different shapes and specifications as needed to adapt to different application scenarios and glue types.

[0004] In the actual glue spraying process, according to the actual products and processes, it is necessary to use dual-channel or multi-channel nozzles to spray glue at the same time, and the glue spraying intervals of multiple glue spray nozzles need to be adjusted according to actual needs. In the prior art, multiple glue spray nozzles are usually arranged on the same glue pump body, and the multiple glue spray nozzles can slide horizontally within a certain range, thereby playing a role in adjusting the glue spraying intervals of the multiple glue spray nozzles. However, in order to ensure the sealing of the glue spray nozzles, such an adjustment method can only be adjusted within a small range, and the scope of application is small. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a glue spray nozzle with flexible angle adjustment, including a glue pump main body, on which a plurality of adjustable glue spray components are arranged, each adjustable glue spray component includes an adjustable mounting plate, each adjustable mounting plate is provided with a nozzle, and each adjustable mounting plate is provided with a positioning rod on one side close to the glue pump main body, and a rotating positioning hole that cooperates with the positioning rod is provided on the glue pump main body, and arc-shaped positioning holes are provided on both sides of each adjusting mounting plate, and each arc-shaped positioning hole is connected to the glue pump main body by bolts.

[0006] Through the above technical scheme, different from the translational sliding adjustment method of the prior art, the utility model rotates and adjusts the nozzle with the positioning rod as the center, and freely adjusts the spacing between the nozzles when spraying glue by changing the angle between the nozzles. With this setting method, it is only necessary to design the nozzle to be long enough to reduce the moving distance of the connection between the nozzle and the corresponding channel on the glue pump body, which not only ensures the sealing of the connection between the nozzle and the glue pump body, but also expands the adjustment range of the nozzle, thereby improving the application range of the glue spray nozzle.

[0007] Furthermore, each regulating glue spraying assembly also includes a glue outlet hole and an air outlet hole, and the glue outlet hole and the air outlet hole are both arranged on the glue pump body.

[0008] Furthermore, each adjustment mounting plate is provided with an arc-shaped glue inlet groove and an arc-shaped air inlet groove corresponding to the glue outlet hole and the air outlet hole respectively. The glue inlet end of the nozzle is connected with the glue outlet hole through the arc-shaped glue inlet groove, and the air inlet end of the nozzle is connected with the air outlet hole through the arc-shaped air inlet groove.

[0009] Through the above technical solution, whether installing the nozzle or cleaning and maintaining the nozzle, the quick connection and assembly of the nozzle and the glue pump body can be quickly completed.

[0010] Furthermore, flexible sealing gaskets are provided in the arc-shaped glue inlet groove and the arc-shaped air inlet groove.

[0011] By arranging flexible sealing gaskets in the arc-shaped glue inlet groove and the arc-shaped air inlet groove, the sealing performance can be improved. When the angle of the nozzle is adjusted, the arc-shaped glue inlet groove and the arc-shaped air inlet groove can be ensured to be always in a sealed state to avoid glue overflow.

[0012] Furthermore, the adjusting mounting plate is rotatably connected to the rotating positioning hole through a positioning plug rod.

[0013] According to actual production needs, the user can first loosen the bolts on both sides of the adjustment mounting plate, and then adjust the setting angle of the nozzle with the rotating positioning hole as the center. When it is adjusted to a suitable angle, tighten the bolts to complete the angle adjustment of the nozzle. This way, the spraying distance between adjacent nozzle parts can be changed through such angle adjustment.

[0014] Furthermore, a plurality of durable components are arranged on the glue pump body, the number of the durable components is equal to and corresponds one to one with the regulating glue spraying components, each durable component includes two threaded rods, and a threaded groove corresponding to the threaded rod is opened on the glue pump body, and the outer surface of the threaded rod is threadedly connected to the threaded groove.

[0015] Furthermore, a mounting groove is provided on the inner wall of each threaded rod, the number of the mounting grooves is equal to and corresponds to the number of the bolts, and each bolt is threadedly connected to the corresponding mounting groove.

[0016] Furthermore, a polygonal disassembly groove for disassembling and assembling the threaded rod is provided at the front end of the inner wall of each threaded rod.

[0017] In the prior art, when the nozzle needs to be adjusted frequently, the bolt needs to be frequently tightened, which will cause the screw holes on the glue pump body to become thread-slipped, affecting the use of the nozzle. However, with the above technical solution, the bolt is not directly connected to the glue pump body, but is connected by providing a detachable and replaceable threaded rod. When the bolt or threaded rod becomes thread-slipped, it can be replaced in time, thereby extending the service life of the glue nozzle.

[0018] Compared with the prior art, the utility model provides a flexible angle-adjustable glue spray nozzle, which has the following beneficial effects:

[0019] In the utility model, different from the translational sliding adjustment method of the prior art, the utility model uses the positioning rod as the center to rotate and adjust the nozzle. By changing the angle between the nozzles, the spacing between the nozzles when spraying glue can be freely adjusted. With this arrangement, it is only necessary to design the nozzle to be long enough to reduce the moving distance of the connection between the nozzle and the corresponding channel on the glue pump body, which not only ensures the sealing of the connection between the nozzle and the glue pump body, but also expands the adjustment range of the nozzle, thereby improving the application range of the glue spray nozzle.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 6 The utility model provides a technical solution: a glue spray nozzle with flexible angle adjustment, including a glue pump body 1, on which a plurality of adjustable glue spray components are arranged, each of which includes an adjustable mounting plate 3, on which a nozzle 2 is arranged, and on which a positioning rod 10 is arranged on a side of each adjusting mounting plate 3 close to the glue pump body 1, and on which a rotating positioning hole 6 cooperating with the positioning rod 10 is provided on the glue pump body 1, and on which arc-shaped positioning holes 4 are provided on both sides of each adjusting mounting plate 3, and each arc-shaped positioning hole 4 is connected to the glue pump body 1 by a bolt 5.

[0029] In the utility model, different from the translational sliding adjustment method of the prior art, the utility model uses the positioning rod 10 as the center to rotate and adjust the nozzle 2. By changing the angle between the nozzles 2, the spacing between the nozzles 2 when spraying glue can be freely adjusted. In this setting method, it is only necessary to design the nozzle 2 to be long enough to reduce the moving distance of the connection between the nozzle 2 and the corresponding channel on the glue pump body 1, which not only ensures the sealing of the connection between the nozzle 2 and the glue pump body 1, but also can expand the adjustment range of the nozzle 2, thereby improving the application range of the glue spray nozzle.

[0030] See also Figure 3-Figure 4 The adjusting mounting plate 3 is rotatably connected to the rotating positioning hole 6 through the positioning rod 10. The user can first loosen the bolts 5 on both sides of the adjusting mounting plate 3 according to actual production needs, and then adjust the setting angle of the nozzle 2 with the rotating positioning hole 6 as the center. When it is adjusted to a suitable angle, the bolt 5 is tightened to complete the angle adjustment of the nozzle 2, so that the glue spraying distance between the adjacent nozzles 2 can be changed through such angle adjustment.

[0031] See also Figure 3-Figure 4 Each adjustable glue spraying assembly also includes a glue outlet hole 8 and an air outlet hole 9, which are both arranged on the glue pump body 1. Each adjustable mounting plate 3 is provided with an arc-shaped glue inlet groove 11 and an arc-shaped air inlet groove 12 corresponding to the glue outlet hole 8 and the air outlet hole 9 respectively. The glue inlet end of the nozzle 2 is connected to the glue outlet hole 8 through the arc-shaped glue inlet groove 11, and the air inlet end of the nozzle 2 is connected to the air outlet hole 9 through the arc-shaped air inlet groove 12.

[0032] It should be noted that, no matter the nozzle 2 is installed or the nozzle 2 is cleaned and maintained, the quick connection and assembly of the nozzle 2 and the glue pump body 1 can be completed quickly.

[0033] See also Figure 3-Figure 4 Flexible sealing gaskets 7 are provided in the arc-shaped glue inlet groove 11 and the arc-shaped air inlet groove 12. By providing flexible sealing gaskets 7 in the arc-shaped glue inlet groove 11 and the arc-shaped air inlet groove 12, the sealing performance can be improved. When the angle of the nozzle 2 is adjusted, it can be ensured that the arc-shaped glue inlet groove 11 and the arc-shaped air inlet groove 12 are always in a sealed state to avoid glue overflow.

[0034] See also Figure 5-Figure 6 A plurality of durable components are arranged on the glue pump body 1, and the number of the durable components is equal to and corresponds to the number of the regulating glue spraying components. Each durable component includes two threaded rods 14. A threaded groove 13 corresponding to the threaded rod 14 is provided on the glue pump body 1. The outer surface of the threaded rod 14 is threadedly connected to the threaded groove 13. A mounting groove 15 is provided on the inner wall of each threaded rod 14. The number of the mounting grooves 15 and the bolts 5 are equal and correspond one to one. Each bolt 5 is threadedly connected to the corresponding mounting groove 15. A polygonal disassembly groove 16 for disassembling and assembling the threaded rod 14 is provided at the front end of the inner wall of each threaded rod 14.

[0035] In the prior art, when the nozzle 2 needs to be adjusted frequently, the bolt 5 needs to be frequently turned, which will cause the screw hole on the glue pump body 1 to become thread-slipped, affecting the use of the nozzle 2. Compared with the prior art, the utility model does not directly connect the bolt 5 to the glue pump body 1, but rather connects it by providing a removable and replaceable threaded rod 14. When the bolt 5 or the threaded rod 14 becomes thread-slipped, it can be replaced in time, thereby extending the service life of the glue nozzle. When the threaded rod 14 needs to be replaced, the threaded rod 14 can be disassembled and assembled by simply inserting the corresponding disassembly and assembly tool into the polygonal disassembly and assembly groove 16.
