Description

Technical Field

[0001] The utility model relates to the technical field of glue liquid conveying devices, in particular to a dense glue-discharging type glue applying nozzle. Background Art

[0002] When manufacturing care products such as disposable diapers and sanitary napkins, they need to be bonded together through a glue spraying process. During the glue spraying process, a nozzle is used to spray and deliver the glue liquid.

[0003] In the prior art, glue is usually controlled by a glue supply device, which adds glue to the nozzle in a quantitative manner and discharges it through the nozzle outlet to spray glue on the product. For some long strip products, a glue nozzle with a rectangular glue spray outlet is usually required. The glue outlet and compressed air outlet of this type of glue nozzle are usually arranged in a straight line and crossed. This results in a smaller number of glue outlets that can be set on the glue nozzle at the same width. When it is necessary to spray long strips of glue, the amount of glue discharged at the same width will also be smaller. The result reflected on the product is that the glue sprayed on the product becomes thin, which ultimately leads to insufficient adhesion of the product and difficulty in meeting actual glue spraying needs.

[0004] To this end, we proposed a dense glue-discharging type glue nozzle. Utility Model Content

[0005] The purpose of the utility model is to provide a dense glue-discharging type glue-dispensing nozzle to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a dense glue-discharging type glue-dispensing nozzle, comprising a nozzle mounting seat and a glue-inlet channel and an air-inlet channel provided on the nozzle mounting seat, and further comprising a fastening clamping plate detachably connected to the nozzle mounting seat, with a multi-piece glue-discharging assembly provided between the nozzle mounting seat and the fastening clamping plate:

[0007] The multi-piece glue discharge assembly consists of a glue discharge sheet located in the middle and jet components located on both sides of the glue discharge sheet, which are arranged in sequence. The glue discharge sheet is provided with multiple glue discharge slots for discharging glue. The jet components include an air discharge sheet, which is provided with multiple air discharge slots for exhausting.

[0008] Through the above technical solution: the glue discharge structure is set to a multi-piece structure, and by distributing multiple air outlet slots on both sides of the film discharge sheet, multiple glue discharge slots can be set as needed on a straight line of the film discharge sheet, and will not affect the delivery of compressed air by the air outlet slots. Through such improvements, more glue discharge slots can be opened without changing the width of the film discharge sheet, thereby increasing the glue discharge amount at the same width, and the glue sprayed on the product becomes thicker, ensuring the adhesion of the product to meet the actual glue spraying needs.

[0009] Furthermore, a fastening bolt is threadedly connected to the nozzle mounting seat, and the fastening bolt passes through the multi-piece glue discharge assembly in sequence and is threadedly connected to the fastening clamping plate.

[0010] Through the above technical solution, the installation and disassembly of the nozzle can be completed quickly.

[0011] Furthermore, the multi-piece glue discharging assembly also includes two side clamping plates and two first connecting plates. The two side clamping plates are respectively fitted with the nozzle mounting seat and the fastening clamping plate, and both side clamping plates are provided with transfer grooves.

[0012] Furthermore, two first connecting pieces are respectively arranged on both sides of the film outlet sheet, two air outlet pieces are provided, and each air outlet piece is connected to the film outlet sheet through a first connection.

[0013] Through the above technical solution: the two air outlet pieces are respectively located on both sides of the glue outlet piece, and then air can be blown synchronously from both sides of the glue outlet slot to the middle glue outlet slot, which can better form airflow at the glue outlet slot, and can assist in better atomization of the glue liquid, so that the glue liquid can be sprayed out in a smaller particle state, thereby increasing the coverage area and uniformity of the glue liquid.

[0014] Furthermore, air guide holes are provided on the film outlet plate, the first connecting plate, the air outlet plate and the side clamping plate close to the nozzle mounting seat, and the air guide holes are connected to the air inlet channel.

[0015] Furthermore, a plurality of glue guiding grooves are provided on the first connecting piece and the air outlet piece close to the fastening bolt, and the glue guiding grooves are used to connect the glue inlet channel with the plurality of glue outlet grooves.

[0016] Furthermore, a plurality of air guiding grooves are provided on the film outlet sheet, the first connecting sheet and the air outlet sheet, and the plurality of air guiding grooves are used to connect the plurality of air outlet slots with the air inlet channel.

[0017] Furthermore, the transfer grooves provided on the side plates close to the fastening plates are used to connect the multiple air guide holes with the multiple air guide grooves.

[0018] Through the above technical solution: the glue liquid in the glue inlet channel can be transported to multiple glue outlet slots and discharged, while not affecting the process of compressed air entering the multiple air outlet slots from the air inlet channel and being discharged, so that the transportation of glue liquid and gas can be independently controllable and can be adjusted according to actual needs, which is more in line with actual production needs.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] In the present invention, the glue discharge structure is set as a multi-piece structure, and by distributing a plurality of air outlet slots on both sides of the film discharge sheet, a plurality of glue discharge slots can be set as needed on a straight line of the film discharge sheet, and will not affect the delivery of compressed air by the air outlet slots. Through such an improvement, more glue discharge slots can be opened without changing the width of the film discharge sheet, thereby increasing the glue discharge amount at the same width, and the glue sprayed on the product becomes thicker, ensuring the adhesion of the product to meet the actual glue spraying needs.

The jet components include an air discharge sheet 10, and the air discharge sheet 10 is provided with a plurality of air discharge slots 13 for exhausting.

[0035] In the present invention, the glue discharge structure is set as a multi-piece structure, and by distributing multiple air outlet slots 13 on both sides of the film discharge sheet 8, multiple glue discharge slots 12 can be set as needed on a straight line of the film discharge sheet 8, and will not affect the delivery of compressed air by the air outlet slots 13. Through such improvements, more glue discharge slots 12 can be opened without changing the width of the film discharge sheet 8, thereby increasing the glue discharge amount at the same width, and the glue sprayed on the product becomes thicker, ensuring the adhesion of the product to meet the actual glue spraying needs.

[0036] See also Figure 1-Figure 2 ,as well as Figure 5-Figure 6 The nozzle mounting seat 1 is threadedly connected with a fastening bolt 6, which passes through the multi-piece glue discharge component 5 in sequence and is threadedly connected to the fastening clamp plate 2.

[0037] Through such an arrangement, the nozzle can be quickly installed and disassembled.

A second connecting piece 11 is provided between the two side clamps 7 and the two adjacent air outlet pieces 10. The second connecting piece 11 is provided with a through groove 18 for air to pass through.

[0039] It should be noted that the two air outlet pieces 10 are respectively located on both sides of the glue outlet piece 8, so that air can be blown synchronously from both sides of the glue outlet slot 12 to the middle glue outlet slot 12, which can better form airflow at the glue outlet slot 12, and can assist in better atomization of the glue liquid, so that the glue liquid can be sprayed out in a smaller particle state, thereby increasing the coverage area and uniformity of the glue liquid.

[0043] It should be noted that the delivery path of the glue liquid in this nozzle is that the glue liquid enters the transfer groove 16 from the glue inlet channel 3, then passes through the multiple glue guide grooves 17 and is finally discharged through the multiple glue outlet grooves 12.

[0044] The gas delivery path in this nozzle is that the gas passes through multiple air guide holes 15 from the air inlet channel 4, enters another transfer groove 16, and enters multiple air guide grooves 14 through the through groove 18, and is finally discharged through multiple air outlet grooves 13 on both sides of the film 8.
