Detailed Description

The utility model is further described with reference to the following figures and specific embodiments.

As shown in fig. 1-2, this embodiment provides a convenient-to-clean glue spraying head, including the valve seat 10 with the mixed glue cavity 11, the lower extreme of valve seat 10 is connected with the play glue pipe 20 that communicates with mixed glue cavity 11, and still set up the first glue inlet hole that communicates with mixed glue cavity 11 on the valve seat 10 respectively, the second enters the glue hole, wash hole 12 and inlet port 13, wherein, it arranges vertically to go out glue pipe 20, so that improve out the glue speed with the help of gravity, the first glue inlet hole, the second enters the glue hole, wash hole 12 and inlet port 13 all set up on valve seat 10 week side, of course, inlet port 13 also can set up in the upper end of valve seat 10. In addition, the first glue inlet hole, the second glue inlet hole, the cleaning hole 12 and the air inlet hole 13 are respectively provided with an opening and closing valve 30, and the opening and closing valve 30 is preferably a pneumatic valve; the end of the rubber outlet pipe 20 away from the valve seat 10 is connected with an injection assembly 40. Of course, the valve seat 10 is also provided with a mounting threaded hole.

Preferably, in this embodiment, swing joint has a spiral reamer (not shown in the figure) in the play hose 20, and specifically, the spiral reamer only alternates in a play hose 20, and when glue flowed through the spiral reamer, the spiral reamer can rotate under the effect of glue extrusion force, drives glue in a play hose 20 spiral motion in opposite directions, and at this in-process, glue can constantly overturn, and then promotes the homogeneous mixing of glue.

The rubber outlet pipe 20 is sleeved with a rigid pipe 50 fixedly connected to the valve seat 10, and the injection assembly 40 is fixedly connected to the lower end of the rigid pipe 50. Since the glue outlet pipe 20 and the rigid pipe 50 are respectively fixedly connected with the valve seat 10, the reaction force applied by the injection assembly 40 during injection can act on the valve seat 10 through the rigid pipe 50 and can not be transmitted through the glue outlet pipe 20, which helps to ensure the stability of the glue outlet amount and the accuracy of the glue injection position.

The spraying assembly 40 can be an existing assembly, and this embodiment provides a spraying assembly with relatively good uniformity of glue spraying, where the spraying assembly 40 includes a body 41, one end (i.e., the upper end) of the body is provided with a first connection hole 42 for inserting the glue outlet pipe 20, an inner thread section for connecting to the rigid pipe 50 is provided on an inner side wall of the first connection hole 42, and of course, an outer thread section matched with the inner thread section is required to be provided at the lower end of the rigid pipe 50; the other end of the body 41 is provided with a second connecting hole 43 communicated with the first connecting hole 42, and the second connecting hole 43 is spirally connected with a nozzle 44. Preferably, in order to ensure that the flow rate of the glue is stable, in this embodiment, one end of the glue outlet pipe 20 penetrating into the first connection hole 42 has a reducing section 21, and a positioning sleeve 45 sleeved on the reducing section 21 is disposed in the first connection hole 42.

One end of the nozzle 44, which is far away from the body 41, is provided with a tubular spraying part 46, one end of the body 41, which is far away from the rigid pipe 20, is also fixedly connected with an outer sleeve 47 covering the nozzle 44 in a sealing manner, one end of the outer sleeve 47, which is far away from the body 41, is provided with a through hole, the spraying part 46 is inserted in the through hole, an annular air outlet 48 is formed between the inner side wall of the through hole and the outer side wall of the spraying part 46, and in addition, the body 41 is also provided with an air inlet channel 49 communicated with the inner cavity of the outer sleeve 47. Preferably, the outer periphery of the nozzle 44 is fixedly connected or integrally connected with a convex ring 60 positioned in the inner cavity of the outer sleeve 47, and the convex ring 60 is provided with a plurality of through holes which are uniformly distributed by taking the nozzle 44 as the center, so that the air flow in the outer sleeve 47 can be rectified, and the spraying stability is improved.

Before the use, connect the air supply line on inlet channel 49 and the on-off valve 30 that is connected with inlet port 13 respectively, this air supply line is connected with the air supply, connect cleaner feeding mechanism on the on-off valve 30 that is connected with washing hole 12, connect the gluey bucket of A glue on the on-off valve 30 that is connected with first gluey hole of advancing, connect the gluey bucket of B glue on the on-off valve 30 that is connected with the second gluey hole of advancing, of course, above-mentioned air supply line, air supply, cleaner feeding mechanism, gluey bucket of A glue and gluey bucket of B glue do not belong to a part of this embodiment, need dispose in addition when using. When in use, the glue solution passing through the first glue inlet and the second glue inlet is mixed in the glue mixing cavity 11, flows out from the glue outlet pipe 20, and is driven by the air flow sprayed out from the annular air outlet 48 to be sprayed out from the nozzle 44; when the cleaning is needed, the opening and closing valve 30 connected with the first glue inlet hole and the second glue inlet hole is closed, cleaning agents are injected from the cleaning hole 12, and then high-pressure gas is injected from the air inlet hole 13, so that the cleaning of the glue spraying head is alternately realized.

The present invention is described in detail with reference to the attached drawings, but the embodiments of the present invention are not limited to the above embodiments, and those skilled in the art can make various modifications to the present invention based on the prior art, which fall within the scope of the present invention.
