Description

Technical Field

[0001] This utility model belongs to the technical field of silent tire processing equipment, and in particular relates to a sealant nozzle device for the production of sticky note silent cotton. Background Technology

[0002] With the development of new energy vehicles, these vehicles have eliminated spare tires and traditional internal combustion engines, using electric motors instead. Tire noise has become a major source of noise in new energy vehicles, making noise-reducing and puncture-resistant tires a necessity for owners. Currently, most silent tires are new. To improve the noise reduction of tires in existing new energy vehicles without replacing them with brand-new tires, a sticky noise-reducing foam has been developed. This sticky noise-reducing foam is applied by attaching three strips of sealant of equal width and thickness inside the tire. These three strips are extruded using a sealant nozzle. Due to the high viscosity of the sealant, existing four-way valves with one inlet and three outlets cannot achieve equal flow rates from all three outlets, resulting in uneven width and thickness of the sealant strips, affecting the application quality. Applying one strip of sealant at a time requires three repetitions to complete the process, necessitating position adjustments, increasing equipment complexity and reducing processing efficiency.

[0022] Reference Figure 1-7 As shown, a sealant nozzle device for producing sticky note noise-reducing cotton includes a nozzle body 1, a sealing joint 2, an adjusting stud 3, a plug 4, and an adhesive outlet nozzle 5. The nozzle body 1 has an adhesive inlet hole 11 on its top surface and several adhesive outlet holes 12 on its bottom surface. The nozzle body 1 has a connecting hole 13 on its side surface, and the adhesive inlet hole 11 communicates with each adhesive outlet hole 12 through the connecting hole 13. The nozzle body 1 has an adjusting hole 14 that passes through each adhesive outlet hole 12. The adjusting stud 3 is located at one end of the adjusting hole 14 and extends to the adhesive outlet hole 12. The plug 4 is located at the other end of the adjusting hole 14 and the outer end of the connecting hole 13. The adhesive outlet nozzle 5 has a nozzle plate 51 and an adhesive outlet 52. The nozzle plate 51 is fixed to the bottom surface of the nozzle body 1, and the adhesive outlet 52 is located on the nozzle plate 51 and corresponds one-to-one with the adhesive outlet holes 12.

[0023] The sealant nozzle device's inlet 11 is connected to the sealant delivery pipeline via a sealing connector 2. The adjusting stud 3 is locked in place, the plug 4 is tightened, and the selected outlet nozzle 5, along with its additional sealing ring 7, is locked to the nozzle body 1. During operation, the equipment applies pressure to the sealant. The sealant flows from the inlet 11 of the sealant pipeline nozzle body 1, along the branched channels of the connecting hole 13, into the outlet holes 12, and then into the outlet nozzles 5, forming several uniform strips of sealant from the outlets 52. During processing, an Allen wrench is used to adjust the locking depth of the adjusting stud 3 to control the size of the outlet holes 12 within the cavity, thereby controlling the flow rate of the outlet nozzles 5. Even with high adhesive viscosity, the width and thickness of the flowing strips remain equal, improving the adhesion of the sound-absorbing cotton.

[0024] Furthermore, the nozzle body 1 has a hexagonal cross-section, and the connecting hole 13 is located on both sides near the bottom surface, with the connecting hole 13 perpendicular to the side surface.

[0025] The "hexagonal" nozzle body 1 has a simple structure, which is more in line with the internal pipeline distribution and processing, reducing processing difficulty, reducing materials, and saving manufacturing costs.

[0026] Furthermore, the "hexagonal" nozzle body 1 is symmetrical about the left and right sides of the glue inlet hole 11, and the glue outlet hole 12 is symmetrically distributed about the left and right sides of the glue inlet hole 11; there are 3 glue outlet holes 12.

[0027] It facilitates the adjustment and control of the glue dispensing rate.

[0028] Furthermore, the glue outlet 52 is a strip-shaped glue outlet.

[0029] This forms a strip of adhesive.

[0030] Furthermore, the opening width of the strip-shaped adhesive nozzle gradually increases from the center to both sides, resembling a "dumbbell shape".

[0031] The glue outlet is located in the center of the nozzle. To ensure uniform glue width, the width of the outlet in the middle is reduced, allowing the glue to fill both sides. This ensures that sealant can flow out from both ends of the strip-shaped nozzle, and that the thickness of the flowing sealant is consistent with the thickness in the middle.

[0032] Furthermore, the width difference between the two sides of the strip-shaped adhesive opening and the central opening is 0.4-0.8 mm. Preferably, the difference is 0.6 mm. This dimensional difference results in the sealant thickness flowing out of the strip nozzle being consistent with the thickness in the middle.

[0033] Furthermore, the maximum opening width on both sides of the strip-shaped adhesive nozzle is 1.6-2mm, and the minimum opening width at the center is 1-1.4mm; the opening length of the strip-shaped adhesive nozzle is 18-25mm. Preferably, the maximum opening width is 1.8mm, the minimum opening width at the center is 1.2mm, and the opening length of the strip-shaped adhesive nozzle is 21mm. Furthermore, a glue storage cavity 6 is provided between the glue outlet 12 and the glue outlet 52, and the glue storage cavity 6 is located at the lower end of the glue outlet 12 and / or inside the glue outlet 52.

[0034] Furthermore, the diameter of the glue storage cavity 6 is larger than the diameter of the glue outlet hole 12.

[0035] Furthermore, the sealing joint 2 is a sealing straight-through joint; the adjusting stud 3 is an internal hex bolt.

[0036] Furthermore, sealing rings 7 are respectively provided between the nozzle plate 51 and the glue outlet hole 12, the adjusting stud 3 and the adjusting hole 14, the plug 4 and the adjusting hole 14, and the sealing joint 2 and the glue inlet hole 11.

[0037] To avoid glue leakage.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
