As the gun base is provided with the gun body, the gun needle and the piston; the compression spring is arranged between the back end face of the piston and the internal top end of the nut; the spring-pressure adjusting screw is arranged on the nut and the adjusting screw adopted to adjust the pressure of the compression spring to realize the change of the piston compression; accordingly, the utility model can realize the demands to different coating material spraying and solve the technical problem that the present film coating spray gun can not meet the requirements of the spraying of different coating materials.
Description
Technical field
This utility model relates to the spray gun in a kind of tablet film coating equipment.
Background technology
At present, and since the difference of coating material in the film coating, the method that process that film coating adopts and process will be different from the continuous hydrojet of sugar coating, otherwise can cause the coating rough surface owing to rapid draing, and do not reach the coating requirement.Therefore, coating is carried out in the circulation that needs to adopt whitewashing, homogenate, dry three operation sections to form, and the film coating equipment of prior art is to realize these operations, and especially therefore the spray gun in the film coating equipment, can only be starched dropper with thin film and replace.
Summary of the invention
This utility model is that a kind of film coating spray gun will be provided, and is used to solve the technical problem that existing film coating spray gun can not be applicable to the whitewashing of different coating materials.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of film coating spray gun, comprise gun platform, the rifle body, rifle pin, rifle head, be characterized in: be inserted with the rifle body in the gun platform front end, the rifle body is inserted with the rifle pin, gun platform front end fixed seal connection rifle head, and the rear end is fixedly connected with nut, in nut with gun platform between plunger shaft in the piston of fixedlying connected with the rifle pin is installed, between the top compression spring is installed in the rear end face of piston and the nut; Be provided with spring tension adjusting screw above the nut; Be fixedly connected with inlet suction port on the periphery of gun platform middle part, and the air inlet of inlet suction port communicates with plunger shaft, corresponding rifle body inlet place is provided with inlet on the gun platform.
The rifle head is fixedlyed connected with gun platform with nut, and seals with sealing gasket; Be connected with the feed tube joint on the inlet; Inlet suction port is the plug-in type fast connecting joint.
This utility model compared with prior art has following beneficial effect: because the rifle body is installed in the gun platform, the rifle pin is equipped with the compression spring between the top in the piston, the rear end face of piston and nut; Be provided with spring tension adjusting screw above the nut, regulate the pressure of compression spring by adjustment screw, realize the variation of piston pressure, thereby can realize requirement, solve the technical problem that existing film coating spray gun can not be applicable to the whitewashing of different coating materials the whitewashing of different coating materials.
Description of drawings
Fig. 1 is a structure cutaway view of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, further set forth this utility model.Should be understood that these embodiment only to be used to this utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications this utility model after the content of having read this utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, a kind of film coating spray gun of the present utility model comprises nut 1, compression spring 2, piston 3, rifle pin 4, nut 5, rifle head 6, sealing gasket 7, rifle body 8, adjustment screw 9, gun platform 10 etc.
Be inserted with rifle body 8 in gun platform 10 front ends, rifle body 8 is inserted with rifle pin 4, gun platform 10 front end fixed seal connection rifle heads 6, the rear end is fixedly connected with nut 1, in nut 1 with gun platform 10 between plunger shaft in the piston 3 of fixedlying connected with rifle pin 4 is installed, compression spring 2 is installed between the top in the rear end face of piston 3 and the nut 1; Be provided with spring tension adjusting screw 9 above the nut 1, be used to regulate the pressure of compression spring 2, make pressure on the piston 3 can promote 4 pairs of different coating materials of piston 3 and rifle pin and whitewash.
Be fixedly connected with inlet suction port 12 on the gun platform 10 middle part peripheries, and the air inlet of inlet suction port 12 communicates with plunger shaft, after compressed air enters plunger shaft by air inlet, promote piston 3 and move backward.Corresponding rifle body 8 inlet places are provided with inlet on the gun platform 10.
Assembling process of the present utility model is: earlier rifle body 8 is inserted gun platform 10, load onto rifle head 6 and sealing gasket 7, with special spanner nut 5 is tightened, then rifle pin 4 and piston 3 are inserted from behind, load onto spring 2 back fastening nut 4 and adjustment screw 9.Should guarantee air tight, the leakage of each sealing place after the installation.
