Description
Technical field
The utility model relates to plastic pipe forming equipment, relates in particular to a kind of modified node method of vacuum two-way valve tube forming device.
Background technology
Plastic pipe because of its chemical stability good, strong to the repellence of weak acid and weak base, a lot of field progressively replaces glass and ceramic material, and cheap, and the application of present plastic pipe is more and more extensive, is used gradually in a lot of field, an important link is had cooling forming in current plastic pipe production process, tubing cooling forming equipment is specifically set in vacuum tank, then the air in vacuum tank is taken out, keep being in vacuum state in vacuum tank, then extrude vacuum tank by atmospheric pressure, thus make tube forming, but because current vacuum tank ante-chamber and back cavity utilize vaccum pump motor to be taken away by the air in vacuum tank respectively, produce large pipe needs two vaccum pump motors to start simultaneously, just can reach the vacuum of tube forming, but just only need to start a wherein vacuum level requirements that just can reach midget tube material forming when producing small-sized tubing, if now only start wherein one, another vaccum pump motor is because be connected with the external world, thus cause the effect vacuumized not to be fine, and may the air in the external world be brought in vacuum tank, make vacuum in vacuum tank not up to standard, thus affect midget tube material forming effect, if two start together, waste electric energy.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of modified node method saving the effective vacuum two-way valve tube forming device of electric energy, tube forming.
For achieving the above object, the utility model provides a kind of modified node method of vacuum two-way valve tube forming device, comprises the first vaccum pump motor, the second vaccum pump motor and vacuum tank; Described first vaccum pump motor is provided with the first exhaust tube and downtake pipe; Described second vaccum pump motor is provided with the second exhaust tube and second exhaust pipe; Tubing cooling forming device is provided with in described vacuum tank; Described vacuum tank is divided into ante-chamber and back cavity; Connector and the described ante-chamber of described first exhaust tube are tightly connected; Connector and the described back cavity of described second exhaust tube are tightly connected; Described first exhaust tube and/or the second exhaust tube are provided with manual bidirectional ball valve.
Preferably, the connector of described first exhaust tube is provided with silica gel thin film.
More preferably, the connector of described second exhaust tube is provided with silica gel thin film.
The beneficial effect that the utility model has is: 1, by being provided with manual bidirectional ball valve at the first exhaust tube and/or the second exhaust tube, can select well to open a wherein vaccum pump motor, has saved electric energy; 2, air can not enter vacuum tank, and vacuumizing effect is good, tube forming effective; 3, equipment can produce the tubing of various model neatly.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for description, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.In the accompanying drawings:
Fig. 1 is the front view of the modified node method of this vacuum two-way valve tube forming device.
In figure: 1, the first vaccum pump motor; 2, the second vaccum pump motor; 3, vacuum tank; 4, the first exhaust tube; 5, downtake pipe; 6, the second exhaust tube; 7, second exhaust pipe; 8, ante-chamber; 9, back cavity; 10, manual bidirectional ball valve; 44, the connector of the first exhaust tube; 66, the connector of the second exhaust tube.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figure 1; The modified node method of a kind of vacuum two-way valve of the utility model tube forming device, comprises the first vaccum pump motor 1, second vaccum pump motor 2 and vacuum tank 3; First vaccum pump motor 1 is provided with the first exhaust tube 4 and downtake pipe 5; Second vaccum pump motor 1 is provided with the second exhaust tube 6 and second exhaust pipe 7; Tubing cooling forming device is provided with in vacuum tank 3; Vacuum tank 3 is divided into ante-chamber 8 and back cavity 9; Connector 44 and the ante-chamber 8 of the first exhaust tube 4 are tightly connected; Connector 66 and the back cavity 9 of the second exhaust tube 5 are tightly connected; First exhaust tube 4 and/or the second exhaust tube 6 are provided with manual bidirectional ball valve 10.After adopting said structure, the utility model can realize following work: when producing large pipe, vacuum tank due to needs higher, now ensure that the first exhaust tube 4 and the second exhaust tube 6 are in connected state with vacuum tank 3, start the first vaccum pump motor 1, second vaccum pump motor 2, such 2 vaccum pump motors just can vacuumize process to vacuum tank 3, ensure that the vacuum in vacuum tank 3 reaches the requirement of large pipe cooling forming vacuum, if produce small-sized tubing, only need owing to not needing startup 2 vaccum pump motors to start wherein one, but because exhaust tube is communicated with extraneous connection, even if closedown vaccum pump motor, air still can enter in vacuum tank 3 from the vaccum pump motor of closing, but be provided with at the first exhaust tube 4 and/or the second exhaust tube 6 and just can optionally carry out starting a wherein vaccum pump motor after manual bidirectional ball valve 10, because manual two ball valve 10 is closed rear exhaust tube and would not be in communication with the outside, therefore air also can not enter exhaust tube by vaccum pump motor, thus enter in vacuum tank 3, when therefore producing small-sized tubing, only need to select to close one of them manual bidirectional ball valve 10 and just can ensure normally producing of small-sized tubing, because vacuum is guaranteed, midget tube material forming degree is fine, completely can be up to standard.
In order to ensure that the first exhaust tube 4 is tightly connected with vacuum tank 3 ante-chamber 8, be provided with silica gel thin film (not shown in FIG.) at the connector 44 of the first exhaust tube 4, so just can ensure that the first exhaust tube 4 has been tightly connected with vacuum tank 3 ante-chamber 8 well.
In order to ensure that the second exhaust tube 6 is tightly connected with vacuum tank 3 back cavity 9, the connector 66 of the second exhaust tube (6) is provided with silica gel thin film (not shown in FIG.), so just can ensure that the second exhaust tube 6 has been tightly connected with vacuum tank 3 back cavity 9 well.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
