Description
Technical Field
The utility model relates to a hardware and tools technical field, specifically speaking relates to a hot melt adhesive rifle.
Background
The hot melt glue gun has the development trend that the glue discharging time is shortened and the use is convenient, most glue discharging time of glue guns on the market is about one minute, the glue discharging time of individual glue guns is below 30 seconds, but no glue stopping valve is arranged, and glue discharging is continued after the glue guns are used, so that the use experience of customers is influenced. The heating scheme of our glue gun has shortened the heating time of glue out to 30 seconds, and the rifle thorax embeds has only glues the valve moreover, has guaranteed that the customer uses and has experienced.
SUMMERY OF THE UTILITY MODEL
To solve the above problems, an object of the present invention is to provide an internal heating type hot melt adhesive gun.
In order to achieve the above purpose, the technical solution of the present invention is as follows:
internal heating formula hot melt adhesive gun, including being used for going out the bore of a gun of gluing, characterized by sets up the heating rod in the bore of a gun, and the heating rod outside cover has heat conduction metal covering, and inside heating rod and the vertical bore of a gun that sets up of heat conduction metal covering, the hot melt adhesive setting was entered the mouth at the bore of a gun rear end, and the bore front end sets up out the jiao kou.
The upper end of the heating rod is connected with a lead, and an insulating sleeve is arranged at the joint of the lead and the heating rod. And the lead and the aluminum piece are isolated, so that the short circuit of the heating rod is prevented.
An O-shaped sealing ring is arranged on the joint surface of the metal sleeve and the gun bore. The heated glue is prevented from overflowing from the threaded engagement part of the aluminum piece and the gun bore.
The inner side of the glue outlet is provided with a glue stop valve. After the glue gun is stopped, the glue which is not cooled is prevented from flowing out from the front port of the gun chamber.
The thermistor is arranged outside the gun bore and connected with the main control PCB through a lead, and the main control circuit board is enabled to execute heating or stop heating through temperature sensing of the thermistor so as to keep the temperature in the gun bore within an interval.
The outer side of the bore is provided with a shell which is a detachable bore left shell and a bore right shell. The left and right casings of the gun chamber separate the gun chamber from the casing to prevent the casing from being damaged by high temperature
The rear end of the shell is provided with a rubber sleeve. The heated glue is prevented from overflowing from the rear end of the gun bore.
Glue the rifle, adopt the internal heating formula heating rod, rate of heating is fast, the heating goes out to glue the time and shortens to 30 seconds, the bore embeds in addition has the valve of only gluing, guarantees sealedly, customer experience is good.

Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further described with reference to the following embodiments.
Referring to fig. 1 and 2, internal heating formula hot melt adhesive gun, including being used for going out the bore of a gun 1 of gluing, set up heating rod 5 in the bore of a gun 1, the cover has heat conduction metal covering 7 outside heating rod 5, inside heating rod 5 and the vertical bore of setting of heat conduction metal covering 7, hot melt adhesive 11 set up at the entry of bore of a gun 1 rear end, and the front end of bore of a gun 1 sets up out the jiao kou.
Furthermore, the heat-conducting metal sleeve 7 is made of aluminum, so that the heat-conducting effect is good.
Furthermore, the upper end of the heating rod 5 is connected with a lead, and an insulating sleeve 6 is arranged at the joint of the lead and the heating rod.
An O-shaped sealing ring 8 is arranged on the joint surface of the aluminum alloy metal sleeve 7 and the gun bore.
The inner side of the glue outlet is provided with a glue stop valve 2.
The outer side of the gun chamber 1 is provided with an assembly thermistor 9, and the thermistor and the heating rod are respectively connected with a main control circuit board by leads.
The outer side of the bore 1 is provided with a shell which is a detachable bore left shell 3 and a bore right shell 4.
The rear end of the housing is provided with a rubber sleeve 10.
The assembly steps are as follows:
the stop cock valve 2 is press fitted into the bore 1.
The O-ring 8 is slipped onto the threaded bottom of the aluminum part 7.
And (4) carrying out snap-fit assembly on the aluminum piece 7 and the gun bore thread.
The insulating ring 6 is sleeved on the heating rod 5 and is put into the hole of the aluminum piece 7.
The thermistor is sleeved on the protruding part below the gun bore.
The assembled parts are placed in the left shell of the gun chamber, and then the left shell and the right shell are combined to be interfered.
The rubber sleeve 10 is fitted into the rear end of the bore.
The glue gun of this embodiment theory of operation: the heating rod is used for heating the bore component, so that the hot melt adhesive is changed from solid into fluid and flows out from the front end of the bore.
The working process is as follows: after the glue gun is started, the heating rod is heated to drive the gun chamber to be heated to reach a set temperature range, the glue feeding assembly of the glue gun pushes the glue rod to be pushed forwards and heated into fluid inside the gun chamber, the glue feeding assembly continuously pushes the glue rod to move forwards, and the glue which is the fluid flows out of the front end of the gun chamber.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention.
