Description

Atomizing spray coating rubberizing device of sanitary towel production usefulness

Technical Field

The utility model relates to a be used for sanitary towel trade spraying rubberizing device, especially relate to an atomizing spraying rubberizing device of nozzle area spiral groove.

Background

At present, the manual glue brushing and the glue applying device which applies glue by means of rolling of a machine roller in the sanitary towel industry mainly comprise two types, namely a drip glue applying device and a roller glue applying device. The manual glue brushing and gluing mode is that a glue coating process is carried out on a production line of a forming workshop, a glue coating barrel made of a galvanized iron sheet is used, an iron sheet is inserted into a glue outlet, and a glue receiving box is used below the iron sheet. During operation, an operator needs to pull the iron sheet out and put the glue into the glue receiving box, insert the iron sheet after the box is full, take the glue out of the box by using a brush and paste the glue, and repeat the operation. The method is time-consuming and labor-consuming, and the glue barrel needs to be cleaned every day after work, thereby causing glue waste. The roller glue rolling and coating device of the machine has higher efficiency than a manual glue brushing and coating mode, but has the advantages of time consumption, glue consumption, high cost, uneven distribution of the bonding surface, higher rework rate and lower efficiency. The existing atomizing and gluing device sprays the glue in a radial shape onto the surface of an object to be glued. Only solves the problems that the coating line is not finished and the coating range is not uniform. But the adhesive is more expensive, the cost is high and the adhesive effect is not ideal.

For example, the chinese patent application No. 00267821, a gluing device for a shoe making machine, applied by taiwan full-cutting industries ltd, mainly comprises a base, a cantilever of which is provided with a left and right parallel double-gun type glue wiping rod assembly, a sleeve rod of which is connected in series with a lifting rod, and an automatic glue feeding mechanism at the front end of the rod. It is composed of an up-down telescopic mechanism for pushing the lifting rod, a straight telescopic mechanism for pushing the movable rod, and a transverse telescopic mechanism which is arranged alternately to make the sleeve rod open or close.

Chinese patent No. 200710073535.1, publication No. CN101085437A discloses an atomizing spray coating gumming device. The container with glue solution container is equipped with air inlet and sprayer communicated with glue solution container, and the sprayer is equipped with spiral spray sheet and strong spray cover, and the periphery of the spiral spray sheet is uniformly distributed with air-jet holes capable of making the glue body be uniformly distributed on the surface of the object to be bonded in the form of fog. The glue solution is sprayed out from small holes uniformly distributed on the spiral spraying sheet by a spray head consisting of a spray cover and a spiral spraying sheet, and is sprayed onto the surface of an object to be bonded in a radial shape after being converged by a conical hole at the lower end of the strong spray cover. Only solves the problems that the coating line is not finished and the coating range is not uniform.

SUMMERY OF THE UTILITY MODEL

The utility model provides a technical scheme that technical problem adopted is: the utility model provides a sanitary towel production is with atomizing spraying coating rubberizing device, includes the needle valve body of the glue solution of flowing through, is equipped with lock nut on one of them face of needle valve body, has nut spiro union in the needle valve body on the other face, needle valve body side is equipped with into gluey hole, inlet port and 2 fixed screw holes of needle valve, and the nut is embedded to have spouts the lid, spouts lid lower extreme system to have and to make the glue solution assemble the back and be radial injection's taper hole, and it has the spiral spray piece to spout the lid is embedded, and the equipartition has the fumarole that enables the colloid to be vaporific injection on the circumference of spiral spray piece, and the taper hole has the embedded helicla flute at the edge.

Compared with the prior art, the utility model has the following beneficial effects.

The helicla flute makes gaseous flow direction can change behind each helicla flute of high-pressure gas through, and under the effect of inertial force, high-pressure gas forms the hurricane of high-speed autogyration in the atomizing space, tears glue, forms tiny even atomized particles, has avoided atomizing inhomogeneous, has had big liquid drop or the condition that atomized particles diameter is bigger than normal after atomizing, has guaranteed out gluey even to form the regional increase that makes out gluey area of negative pressure in spout department, economize and glue, high efficiency is swift. The glue solution sprayed on the bonding surface is uniformly distributed. Convenient use, and solves the problems of time and glue consumption, high cost, uneven distribution of the bonding surface, higher rework rate, unsatisfactory bonding effect and low efficiency of the drip gluing device and the roller gluing device.

For further explanation and not limitation of the above-described implementation of the present invention, the following description of the present invention is provided in connection with the accompanying drawings and examples, but the present invention is not limited thereto. All of these concepts should be considered as within the scope of the present disclosure and the present invention.
