Background

The hot melt glue gun has accurate on-off effect and various nozzles, and can meet the requirements of different production lines. The common hot melt glue gun can not deform when used at the high temperature of 200 ℃ for a long time, and the joint is durable. Therefore, the hot melt glue gun is widely applied to hot melt glue strip bonding products of electronic factories, food factories, packaging factories and the like.

In the existing hot melt adhesive gun, the internal structure of the gun body is not reasonable, and usually the hot melt adhesive rod cannot be advanced or the hot melt adhesive can not be normally used when the trigger is pulled. The main reason that the hot melt adhesive gun is inconvenient to use normally is that the adhesive rod cannot be melted rapidly and uniformly in the melting cavity, and particularly when the hot melt adhesive gun is just electrified for use, only the melting cavity close to the position of the gun nozzle is directly heated, and other positions need to wait for the heat conduction of the gun bore to gradually have the temperature for melting the hot melt adhesive rod, so that the hot melt adhesive rod cannot be melted in time to block, and certain blocking feeling can be realized even after the hot melt adhesive gun is used for a period of time. Moreover, the rubber stick can not advance when the trigger is pulled, abrasion can be caused after the trigger is used for a long time, the hole matched with the size of the rubber stick is enlarged, the friction force of the rubber stick can be reduced, and the normal service life is influenced. In addition, most hot melt glue guns have no placement mechanisms such as supports, so that the hot melt glue guns can only be laterally and flatly placed on a workbench, and safety accidents are easily caused by high-temperature gun mouths.

It should be noted that all the directional terms such as "upper" and "lower" referred to herein are used with respect to the view of the drawings, and are only for convenience of description, and should not be construed as limiting the technical solution.

As shown in fig. 1 and 2, a glue gun with a winding heating plate comprises a handle 1 and a gun barrel 2 which are connected with each other, wherein a track, a pipe sleeve 4, a gun chamber 5 and a gun nozzle 6 which are communicated with each other are sequentially arranged in the gun barrel 2 from one end close to the handle 1 to the other end, and a slide block 3 which can reciprocate on the track is arranged on the track;

a trigger 7 is hinged between the handle 1 and the barrel 2, one end of the trigger 7 is hinged with a connecting rod 8, and the connecting rod 8 is hinged with the sliding block 3, so that the sliding block 3 can push the hot melt adhesive rod into the pipe sleeve 4;

the pipe sleeve 4 comprises a hard sleeve 41 and a soft sleeve 42, the hard sleeve 41 is fixedly connected with the shell of the gun barrel 2, and the soft sleeve 42 is used for connecting the hard sleeve 41 and the gun chamber 5;

the shell of the gun chamber 5 is wrapped with an electrothermal film 51, and the electrothermal film 51 is electrically connected with a switch 9 and a battery 10 which are arranged in the handle 1 in sequence through lead wires 52;

the gun nozzle 6 is sleeved with a protective sleeve 61, and the protective sleeve 61 is fixedly connected with the shell of the gun barrel 2.

The utility model discloses can fix each part in the rifle pipe to melting the stick of gluing and forming the hot melt adhesive and use, electric heat membrane 51 can make the melting chamber thermally equivalent in the bore of a gun 5, realizes better melting effect. The utility model discloses during the use, the linkage of 7 accessible connecting rods 8 of trigger is pulled, makes slider 3 slide on the track, and then pushes the hot melt adhesive stick to in pipe box 4. The fixed connection of the hard sleeve 41 and the protective sleeve 61 enable the gun nozzle 6 to be fixedly connected with the shell of the gun barrel 2, so that the gun chamber 5 connected between the hard sleeve and the gun barrel is fixed at a corresponding position, and the hot melt adhesive rod can enter the melting cavity of the gun chamber 5 after penetrating through the pipe sleeve 4 through the connection of the soft sleeve 42. The electric heating film 51 wrapped on the outer shell of the gun chamber 5 generates heat after being electrified, the heat is uniformly transmitted into the melting cavity of the gun chamber 5, the glue stick is melted, and the generated liquid hot melt glue can flow out of the gun nozzle 6 for use.

Because electric heat membrane 51 can be rolled up to wrap up peripherally, bore 5 is made for the aluminum alloy material to conveniently carry out heat-conduction, simultaneously, it has certain hardness, is equipped with two archs that are used for mutually the joint with the casing of barrel 2 on the 5 shells of bore, and electric heat membrane 51 wraps up between two archs. The two protrusions are used for being clamped with the shell of the gun barrel 2 to further fix the relative position of the gun chamber 5, and are also used for limiting the electric heating film 51, so that the electric heating film is more convenient to position during replacement and installation.

In one embodiment, the end of the bore 5 near the sleeve 4 is provided with an external thread, and the soft sleeve 42 is a silicone sleeve and is sleeved between the hard sleeve 41 and the bore 5. The soft cover 42 of silica gel is established between hard cover 41 and bore 5 for forming different materials, and silica gel is also comparatively stable simultaneously to reduce heat-conduction's emergence, make the heat keep in bore 5, avoid extending to in the hard cover 41, thereby avoid liquid hot melt adhesive to flow to the rear end of barrel 2. In addition, the external thread on the bore 5 is for increasing the friction force with the soft sleeve 42, so that the sleeving between the two is more stable, and meanwhile, one of the two bulges close to the soft sleeve 42 also has a limiting effect on the sleeving of the soft sleeve 42.

In one embodiment, a limiting sleeve 53 is arranged at one end of the bore 5 close to the nozzle 6, a steel ball 62 matched with the limiting sleeve 53 is arranged in the nozzle 6, and an elastic piece 63 for enabling the steel ball 62 to be close to the limiting sleeve 53 is further arranged in the nozzle 6. This elastic component 63 is the pressure spring, under the circumstances of not atress for make steel ball 62 be close to stop collar 53, thereby when stop collar 53 avoided steel ball 62 to get into bore of a gun 5, realize certain sealed effect to this passageway, avoid melting into liquid hot melt adhesive refluence when not using gluey rifle. When the hot melt adhesive pressing device is normally used, the force for pushing the hot melt adhesive rod by pulling the trigger 7 is enough to compress the pressure spring, so that the steel ball 62 is temporarily far away from the limiting sleeve 53 to enlarge the flow channel.

The sliding block 3 can be arranged to be solid, a hot melt adhesive rod can be put in from an opening above the gun barrel 2, and the sliding block 3 is pushed into the pipe sleeve 4; it is also possible to arrange: the hole with hot melt adhesive stick looks adaptation is seted up at slider 3 middle part, and the bottom that corresponds the hole on the connecting rod 8 is equipped with top 31, and connecting rod 8 and slider 3's articulated department is located between the articulated department of top 31 and connecting rod 8 and trigger 7, and the hot melt adhesive stick entry has been seted up to the orbital entry end that corresponds on the shell of barrel 2, and the inboard cover in hot melt adhesive stick entry is equipped with ends sliding ring 11.
