Abstract

This utility model discloses a hot melt adhesive machine with an aeration disc and a connecting tube, relating to the field of hot melt adhesive machines. It includes a storage tank, with an aerator fixed to one side of the top of the storage tank. An aeration disc is fixed to the top of the inside of the storage tank, and the aeration disc has an internal cavity. Multiple aeration pipes are connected to the bottom of the aeration disc. When the aerator is activated, the gas generated by the aerator passes sequentially through the aeration disc and the multiple aeration pipes, and is finally discharged from the aeration holes. Because multiple aeration pipes are installed and inserted into the hot melt adhesive, and the multiple aeration holes are at different depths within the hot melt adhesive, gas can be introduced into different positions and heights of the hot melt adhesive within the storage tank, ensuring thorough mixing and more uniform heating of the hot melt adhesive. This effectively prevents sedimentation and solidification of the hot melt adhesive. Simultaneously, the impact force of the gas improves the fluidity of the hot melt adhesive, facilitating discharge.

[0002] Hot melt adhesive machines are automated application equipment mainly used for hot melt adhesive spraying, scraping, rolling, coating, and dispensing. They are widely used in household products (diapers, sanitary napkins, mousetraps, cockroach traps, and other disposable items), the automotive industry (interior sealing, headlight manufacturing, windshield assembly, air filters, non-woven fabric lamination, footwear, printing, electronic product assembly, clothing, self-adhesive labels), the packaging industry (cardboard packaging, cigarette box packaging, Tetra Pak beverage packaging), the coating and laminating industry (label paper, double-sided label tape, medical breathable tape), bookbinding, and other industries.

[0003] For example, a patent entitled "A Hot Melt Adhesive Machine for Connecting Tubes with Aeration and Anti-Sedimentation Function" (patent application number: CN201921790481.5) discloses a hot melt adhesive machine for connecting tubes with aeration and anti-sedimentation function. An aerator is fixedly installed on one side of the top of the storage tank. The output end of the aerator is fixedly connected to the air pipe through a diverter pipe. An aeration disc is fixedly installed at one end of the air pipe that extends into the storage tank. Several aeration holes with equal spacing are fixedly opened at the bottom of the aeration disc. The gas generated by the aerator is input into the hot melt adhesive through the air pipe and the aeration disc, so that the hot melt adhesive is fully mixed and heated more evenly, effectively preventing the hot melt adhesive from settling. However, the volume of the aeration disc is limited, and the aeration disc is only at a certain height in the storage tank, so the gas cannot be input into the hot melt adhesive at different heights.

[0004] Therefore, it is necessary to propose a hot melt adhesive machine with an aeration disc for the adhesive tube to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a hot melt adhesive machine with an aeration disc to solve the problem in the prior art where the aeration disc has a limited volume and is only located at a certain height in the storage tank, and gas cannot be introduced into the hot melt adhesive at different heights.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hot melt adhesive machine with an aeration disc, comprising a storage box, an aerator fixed to one side of the top of the storage box, an aeration disc fixed to the top inside the storage box, a cavity inside the aeration disc, a plurality of aeration pipes connected to the bottom of the aeration disc, a plurality of aeration holes evenly distributed along the height direction on the aeration pipes, the plurality of aeration holes being connected to the interior of the corresponding aeration pipes, and a pipe connected to the bottom of the aerator, the bottom of the pipe being connected to the interior of the cavity;

[0007] One end of the storage tank is connected to a glue dispensing pipe, and the other end of the glue dispensing pipe is connected to a hot melt glue nozzle.

[0008] Preferably, an inclined block is fixed to the bottom of the inner wall of the storage box, and the inclined block is inclined downward on the side near the dispensing pipe.

[0009] Preferably, the inclined block is provided with an electric heating tube inside, and the height of the downward inclined end of the inclined block is lower than the height of the dispensing tube.

[0010] Preferably, the top of the storage box is provided with a feeding port, which is connected to the inside of the storage box, and the feeding port is provided with a threaded cap.

[0011] Preferably, the bottom of the storage box is connected to an insulation box, and the bottom of the insulation box is fixed with a base plate.

[0012] Preferably, a transparent window is provided on one side of the storage box along the height direction.

[0013] Preferably, the top of the storage box is provided with an exhaust port, and a filter element is provided inside the exhaust port.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] In the actual operation of this utility model, by starting the aerator, the gas generated by the aerator passes through the aeration disc and multiple aeration pipes in sequence, and is finally discharged from the aeration holes. Since there are multiple aeration pipes, which are inserted into the hot melt adhesive, and the multiple aeration holes are at different depths of the hot melt adhesive, the gas can be introduced into different positions and heights of the hot melt adhesive in the storage tank, so that the hot melt adhesive is fully mixed and heated more evenly, effectively preventing the hot melt adhesive from settling and avoiding the hot melt adhesive from solidifying. At the same time, the impact force of the gas can improve the fluidity of the hot melt adhesive, making it easier to discharge.

[0016] In the actual operation of this utility model, the tilt angle of the upper surface of the tilt block can facilitate the flow of hot melt adhesive and facilitate the hot melt adhesive to flow to the dispensing pipe for discharge. At the same time, the electric heating tube can heat and keep the hot melt adhesive inside the storage box warm to prevent solidification. Attached Figure Description
