Abstract
The utility model relates to a hand-operated hot-melt adhesive gun for pasting by using gum as raw material. The hot-melt adhesive gun of the utility model comprises a heating body, a heat conduction body, an outer casing, a protection adhesive ring, a propulsion seat, etc. A piston is arranged in the front end of the heat conduction body which is provided with the heating body, a lock catch is arranged on the bottom of the movable propulsion seat, and a return catapult is connected with a trigger through a draw rod. A hot-melt adhesive strip is locked by the trigger through the lock catch and the propulsion seat, a heat insulating loop is arranged between the heat conduction body and the protection adhesive ring, and a locking device is arranged on the entering direction of the hot-melt adhesive strip. Compared with the prior art, the utility model overcomes the problem that melt adhesive flows out from the tail part of an adhesive gun, so the melt adhesive can be prevented from flowing back or flowing into mechanical devices of the adhesive gun to make the entire product can not be used. The service life of the utility model is prolonged, the use safety performance of the utility model can be improved, and the adhesive injecting process of the utility model is smooth and convenient.
Description
Technical field
The utility model relates to a kind of manual thermosol gelgun that is raw material with the colloid, is used for pasting.
Background technology
General thermosol gelgun in use, the hot melt adhesive tape enters in the heat carrier and owing to hot transmission causes continuing fusing backward melten gel is flowed out after the fusing, the volume of colloidal sol can expand thereupon in the process of fusing simultaneously, prolongation with the work fusing time, when being not enough to open the valve of front end piston, the colloidal sol that expands just can force out adhesive tape backward, thereby cause colloidal sol to flow out from glue gun breech portion, and melten gel flows backwards backward and causes melten gel to flow into glue rifle machinery device, cause that entire product can not use, can flow into when serious in the heater and cause electric leakage, serious phenomenon such as short circuit, make product lose function and scrap, and the entail dangers to personal safety.
The utility model content
The purpose of this utility model is to provide a kind of and has overcome colloidal sol and flow out defective, also make more freely suitable, the thermosol gelgun easily of injecting glue process simultaneously from glue gun breech portion.
The purpose of this utility model realizes by following technical proposals: thermosol gelgun comprises heater, heat carrier, shell, protects cushion rubber and advance seat etc., the built-in piston of heat carrier front end of heater is housed, snap close is equipped with in movable advance seat bottom, connect return catapult and deduction by pull bar, deduction pins the hot melt adhesive tape through snap close and advance seat, described heat carrier and protect and be provided with the thermal resistance circle between the cushion rubber.
The orientation that enters of hot melt adhesive tape of the present utility model is provided with locking device.
The utility model compared with prior art, because having overcome colloidal sol flows out from glue gun breech portion, melten gel is flow backwards cause melten gel to flow into the mechanical device of glue rifle backward and cause entire product and can not use, improved the service life and the usage safety performance of product, also made the injecting glue process more freely suitable, convenient simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail: as shown in Figure 1, thermosol gelgun comprises heater 1, heat carrier 3, shell 4, protects cushion rubber 6 and advance seat 7 etc., the built-in piston 2 of heat carrier 3 front ends of heater 1 is housed, snap close 9 is equipped with in movable advance seat 7 bottoms, connect return catapult 10 and deduction 14 by pull bar 11, deduction 14 pins hot melt adhesive tape 16 through snap close 9 and advance seat 7, heat carrier 3 and protect and be provided with thermal resistance circle 5 between the cushion rubber 6, the orientation that enters of hot melt adhesive tape 16 is provided with locking device.
Thermal resistance circle 5 of the present utility model is devices that prevent that PUR from flowing backwards, and heat before and after it can be separated makes the temperature of heat carrier not pass to the rear from the place ahead, thereby the colloidal sol at rear is not easy to soften, and colloidal sol just is not easy to flow backwards.
Locking device of the present utility model is that a thermosol adhesive tape is locked backward, and is just firmly stuck after the thermosol adhesive tape forward impelling, can not draw back again, and whole exactly adhesive tape plug of result into the glue hole, and colloidal sol can not be flow backwards by the back again when inner melten gel was expanded.Hook hole 17 is in order to keep product when suspention, and the rifle mouth makes progress slightly, makes not spill-over of PUR, does not flow backwards.Because most of thermosol gelgun user, only thermosol gelgun is lain against on the table top, and in fact glue rifle user preferably the glue rifle with the spring use of slinging, its Yu place does not take the table top operating position, also because the rifle mouth makes progress, and melten gel is difficult for spill-over, again owing to the rifle mouth makes progress, it is too high that temperature is not easy the back surface temperature to rising, and the hot melt adhesive tape just can not raise with temperature and cause melten gel of back.
Thermal resistance circle 5 of the present utility model is connecting heat carrier 3 and is protecting cushion rubber 6, and heat carrier 3 front ends that heater 1 is housed are built-in with a piston 2; A snap close 9 is equipped with in advance seat 7 bottoms of an activity, connecting return catapult 10 and deduction 14 by pull bar 11, because the motion of deduction 14, locking device pinning hot melt adhesive tape 16 forward impelling that snap close 9 and advance seat 7 are formed will be driven, through protecting cushion rubber 6 and thermal resistance circle 5, make PUR enter heat carrier 3 and carry out hot melt, melten gel behind the hot melt increases the pressure of the hot melt adhesive tape 16 that continues to come in and opens piston valve 2 and flow to required stickup orientation, owing to placed cup scholar 8, make the propelling of hot melt adhesive tape 16 more steady again at advance seat 7 rears.
