Abstract
The utility model relates to a suction type material loading gun which comprises a cavity body. The lower end of the cavity body is provided with a feed outlet, the side wall of the cavity body is provided with a feed inlet which is connected with a feed inlet pipeline, the upper end of the cavity body is provided with a cylinder which is connected with a plunger, the plunger is arranged in the cavity body, the length of the plunger is bigger than the diameter of the feed inlet. People utilizing one cylinder control device can control the works of the cylinder and makes the plunger moves upward and downward; when the plunger opens the feed inlet, the materials in the material storing container pass through the feed inlet and enter into a model inner cavity under the effect of the subpressure; when the plunger closes the feed inlet, the materials stop entering. The utility model can make the feeding evenly, elevates the production speed and also saves the energy wastage.
Description
Technical field:
The utility model relates to a kind of make-up machine of foamed plastics, relates in particular to a kind of by the feed of moulding material and make its device that enters mould impression, particularly a kind of suction-type feeding gun.
Background technology:
In the prior art, make the foam forming machine of cystosepiment and raw material need be sent into mould impression, the method that adopts is provided with a loading hopper above foam forming machine, raw material is placed in the loading hopper, loading hopper is connected with mould impression, utilize compressed air that raw material is applied active force, raw material is sent into mould impression.
Summary of the invention:
Technical problem to be solved in the utility model is: because in the prior art, the foam forming machine of making cystosepiment adopts loading hopper that raw material is sent into mould impression, and the supply of raw material is wayward in the loading hopper, and is reinforced inhomogeneous, cause product density inhomogeneous, influence product quality.The utility model is that the technical scheme that solution above-mentioned technical problem of the prior art is adopted provides a kind of suction-type feeding gun, described this suction-type feeding gun comprises a cavity, the lower end of wherein said cavity is provided with a discharging opening, and the sidewall at described cavity is provided with a charging aperture, further, described discharging opening is connected with the mould impression of foam forming machine, described charging aperture connects a feed pipe, described feed pipe links to each other with the raw material hold-up vessel, be provided with a cylinder in the prior art in the upper end of described cavity, described cylinder connects a piston, described piston is arranged in the described cavity, the length of described piston is greater than the diameter of described charging aperture, further, described piston can be a cylinder, when described piston moves in described cavity, can change the area of section of described charging aperture, thereby change the speed of charging, further, the diameter of described discharging opening is set to 70 millimeters at least, can allow quick feed.The course of work of the present utility model is: a kind of suction-type feeding gun of the present utility model is fixedly installed on the top of foam forming machine, discharging opening wherein is connected with the mould impression of foam forming machine, in described mould impression, apply the negative pressure in the prior art, particularly, an air exhauster can be set in mould impression, produce negative pressure, utilize the work that cylinder control unit in the prior art can control cylinder, piston is moved up and down, when piston is opened charging aperture, under the effect of negative pressure, raw material in the raw material hold-up vessel is by charging aperture and enter mould impression, and when the piston closes charging aperture, raw material stops to enter, further, a plurality of a kind of suction-type feeding guns of the present utility model can be set above foam forming machine, and it is arranged at regular intervals, can be so that charging be even.The utility model and prior art contrast, because in reinforced passage, be provided with the switch of a piston as reinforced passage, and utilize the negative pressure in the mould impression that raw material is sucked, so can be equably to the mould impression feed, Jia Liao speed can be controlled easily simultaneously, improve the speed of producing, saved energy consumption again.
Description of drawings:
Fig. 1 is the schematic diagram of a kind of suction-type feeding gun of the utility model.
The specific embodiment:
As shown in Figure 1, a kind of suction-type feeding gun of the utility model, comprise a cavity 1, the lower end of wherein said cavity 1 is provided with a discharging opening 2, and the sidewall at described cavity 1 is provided with a charging aperture 3, further, described discharging opening 2 is connected with the mould impression of foam forming machine, described charging aperture 3 connects a feed pipe 4, described feed pipe 4 links to each other with the raw material hold-up vessel, be provided with a cylinder 5 in the prior art in the upper end of described cavity 1, described cylinder 5 connects a piston 6, and described piston 6 is arranged in the described cavity 1, the length of described piston 6 is greater than the diameter of described charging aperture 3, when described piston 6 moves, can change the area of section of described charging aperture 3 in described cavity 1, thereby change the speed of charging.In a preferred embodiment of the present utility model, described piston 6 is a cylinder, also be cylinder between the motor area of piston 6 in the described cavity 1, the diameter of described discharging opening 2 is set to 80 millimeters, the course of work of the present utility model is: a kind of suction-type feeding gun of the present utility model is fixedly installed on the top of foam forming machine, discharging opening 2 wherein is connected with the mould impression of foam forming machine, in described mould impression, apply the negative pressure in the prior art, particularly, an air exhauster can be set in mould impression, produce negative pressure, utilize the work that cylinder control unit in the prior art can control cylinder 5, piston 6 is moved up and down, when piston 6 is opened charging aperture 3, under the effect of negative pressure, the raw material in the raw material hold-up vessel is by charging aperture 3 and enter mould impression, when piston 6 sealing charging apertures 3, raw material stops to enter, and has reached the effect of control feed.When the utility model is applied on the EPS sheet-forming machine in the prior art, upside at the EPS sheet-forming machine, whenever be separated by 1 meter, a suction-type feeding gun of the present utility model be set, can reach reinforced rapidly, density evenly, reduce the good effect of energy consumption.
