Description
Technical Field
The utility model belongs to the technical field of plastic processing, a blowing machine material suction device is related to.
Background
Granular plastic particles enter a blow molding machine through a material suction device to enter a hot melting mode, however, the granular material is in a form between fluid and non-fluid, and under the action of air flow, parameters such as adsorption force, negative pressure in a pipeline and the like of the material are difficult to keep stable in the adsorption process, so that great errors are caused to the feeding amount in unit time, and the quality of products is not facilitated.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a blowing machine inhales material device to the above-mentioned problem that prior art exists, the utility model aims to solve the technical problem how to adjust negative pressure fluctuation, improve the pan feeding precision.
The purpose of the utility model can be realized by the following technical proposal: the utility model provides a blowing machine inhales material device, its characterized in that, this inhale material device includes the inlet pipe and inhales the material pipe, the inlet pipe includes pan feeding end and discharge end, be an inclination between pan feeding end and the discharge end, the discharge end stretch into to inhale in the material pipe, inhale the upper end of material pipe and pass through a tip cap closure inhale the upper end opening of material pipe, sliding connection has a piston on inhaling the inner wall of material pipe upper end, the fixed guide bar that is provided with of up end of piston, guide bar sliding connection is on the tip cap, the cover is equipped with on the guide bar and leans on the reset spring who leans on between end cover and the piston, and the material is perpendicular from discharge end spun direction the lower terminal surface of piston, inhale the lower extreme of material pipe and connect an air exhauster.
The suction pipe is sucked by the exhaust fan to generate negative pressure, the negative pressure acts on the piston with a smoother airflow path at first, the piston moves downwards, the piston is close to the opening of the discharge end, the space allowing discharge is reduced, the larger the negative pressure in the suction pipe is, the closer the piston is to the opening of the discharge end, and certain fluctuation can be caused to the negative pressure in the suction pipe due to circulation of granular materials in the suction pipe.
In the above-mentioned material suction device for a blow molding machine, an adjusting nut is connected to the guide rod by a thread.
The adjusting nut can adjust the maximum displacement of the guide rod, so that the minimum flow cross section of the discharge end is controlled.
Drawings
Fig. 1 is a sectional view of the present suction device.
In the figure, 1, a feed pipe; 11. a feeding end; 12. a discharge end; 2. a material suction pipe; 3. a piston; 4. a guide bar; 5. a return spring; 6. and adjusting the nut.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1, this inhale material device includes inlet pipe 1 and inhales material pipe 2, inlet pipe 1 includes pan feeding end 11 and discharge end 12, be an inclination between pan feeding end 11 and the discharge end 12, discharge end 12 stretches into to inhale in material pipe 2, inhale the upper end of material pipe 2 and inhale the upper end opening of material pipe 2 through a tip cap closure, it has a piston 3 to inhale sliding connection on the inner wall of material pipe 2 upper end, the fixed guide bar 4 that is provided with of up end of piston 3, guide bar 4 sliding connection is on the tip cap, the cover is equipped with reset spring 5 that leans on between end cap and piston 3 on the guide bar 4, the material is from the perpendicular lower terminal surface of piston 3 of discharge end 12 spun direction, inhale the lower extreme connection air exhauster of material pipe 2.
The suction pipe 2 is sucked by the exhaust fan to cause negative pressure, the negative pressure is firstly acted on the piston 3 with a smoother airflow path, the piston 3 is made to move downwards, the piston 3 is close to the opening of the discharge end 12, the space allowing discharging is reduced, the larger the negative pressure in the suction pipe 2 is, the closer the piston 3 is to the opening of the discharge end 12, certain fluctuation can be caused to the negative pressure in the suction pipe 2 due to the fact that granular materials circulate in the suction pipe 2, through the structure, when the negative pressure is increased, the negative pressure in the feed pipe can be reduced due to the fact that the opening caliber of the discharge end 12 is reduced, the circulation cross section is reduced, otherwise the negative pressure in the feed pipe can be increased, and further the pressure change in the feed pipe 1 is buffered, the feeding uniformity in unit time is improved, and.
An adjusting nut 6 is connected to the guide rod 4 through threads. The adjusting nut 6 enables the maximum displacement of the guide rod 4 to be adjusted, thereby controlling the minimum flow cross-section of the discharge end 12.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
