Abstract
The utility model discloses a pulp mould pressed pull tube type valve which comprises an outer pipe 1, wherein, the outer side of the outer pipe 1 is connected with a pipe 2 which is communicated with the outer pipe 1. The inner part of the outer side 1 is provided with an inbuilt pipe 3 which can slide in the outer pipe 3. The inbuilt pipe 3 is provided with a hole 4. The valve can move synchronously with machinery for controlling a transferring die and gradually get close into a die groove with the transferring die. A vacuum via hole in the valve is opened gradually from a small state to a big state till a needed vacuum degree absorbs pulp wet blanks in the transferring die. When An absorption process is finished and water needs to be drained, the transferring die gets away from the die groove gradually and the vacuum via hole is closed gradually. The utility model has the advantages of favorable closeness, energy saving, high reliability, etc.
Description
Technical field:
The utility model relates to a kind of valve.Especially a kind of pull-tube type valve that is used for pulp molding technology.
Background technique:
At present, the pulp molding technology is widely used, by technologies such as pre-shaping, typing, cross cuttings, can produce pulp molding products such as disposable snack box, instant noodle bowl, various pallets.Pre-shaping in the existing pulp molding technology all be by vacuum adsorption method with paper pulp moulding on mould, valve all is installed in the vacuum-pumping pipeline, valve opens wide when vacuumizing, valve closing during draining, used valve has solenoid valve, steam valve etc. usually.But because paper pulp has many fibers and thickness, therefore the spool blocking phenomenon often takes place in existing valve.And because at every turn when vacuumizing, existing valve is all opened, when causing paper pulp upper mould (transfer mould) and counterdie also not to have matched moulds, whole vacuum-pumping pipeline just is in strong vacuum state, wastes a large amount of energy.
Summary of the invention:
The purpose of this utility model is in order to solve the shortcoming that the existing in prior technology spool easily blocks up, wastes energy, but a kind of energy saving, pulp molding pull-tube type valve that reliability is high are provided.
Technical solution of the present utility model is: a kind of pulp molding pull-tube type valve, be provided with outer tube 1, and be connected to the pipe 2 that communicates with outer tube 1 outside the outer tube 1, be provided with the built-in pipe 3 that can in outer tube 1, slide in the outer tube 1, built-in pipe 3 is provided with hole 4.
Described pipe 2 is provided with seal ring 5 with outer tube 1 connecting part.
The utility model can shift the mechanical synchronization of mould with control, lean on into mold slots gradually along with shifting mould, vacuum through hole in the valve will be by little to opening greatly gradually, up to required degree of vacuum the wet base of paper pulp that shifts in the mould is adsorbed,, shift mould and leave mold slots gradually when absorption finishes when needing draining, the vacuum through hole is closed gradually, the utility model compares with prior art that to have encapsulation good, saves the energy, the reliability advantages of higher.
Description of drawings:
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model: be provided with outer tube 1, porose 6 on the outer tube 1, outside outer tube 1, be connected to pipe 2, pipe 2 is communicated with outer tube 1 by hole 6, pipe 2 and outer tube 1 connecting part are provided with seal ring 5.Be provided with built-in pipe 3 in the outer tube 1, its spacing should guarantee that built-in pipe 3 can be free to slide in outer tube 1, and built-in pipe 3 is provided with hole 4.
During use, the machinery that built-in pipe 3 and control is shifted mould links to each other, makes when shifting mould and falling to mold slots, and built-in pipe 3 glides thereupon, and when the transfer mould left mold slots, built-in pipe was then up thereupon.When shifting mould and fall, the hole 4 on the built-in pipe 3 will be gradually overlaps with hole 6 on the outer tube 1, built-in pipe 3 is communicated, the vacuum passage of formation maximum with pipe 2 by the hole on the outer tube 16; When shifting mould when up, the hole 4 on the built-in pipe 3 will be gradually with outer tube 1 on hole 6 stagger sealing vacuum passage, beginning draining.
