Damage, it is necessary to the defects of for electric consumption, and embodied in the production of micro- cable it is more obvious because micro- cable wall thickness is thin, general setting
0.2mm or so, it is thinner than common cable very much, if vacuum is excessive in forming process, adsorption capacity can be caused excessive, there is depression substandard products.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of energy in view of the deficiency of the prior art
Ensure the continuously adjustable device of vacuum for micro- cable production of micro- cable quality of production..
Technical solution is used by the utility model：A kind of continuously adjustable device of vacuum for micro- cable production, its
It is characterized in that：Including rack, negative pressure generator is equipped with rack, the entrance of the negative pressure generator passes through air inlet pipeline and gas
Source is connected, and outlet is connected by jet pipe with head cavity, and micro- cable cable core is stretched into from the entrance of head, is pierced by from exit,
The inlet and outlet of head with cable core seal arrangement.
By above-mentioned technical proposal, pressure regulator valve is equipped with air inlet pipeline.
By above-mentioned technical proposal, the source of the gas connects pneumatic triple piece, and the pneumatic triplets are connected with pressure regulator valve.
By above-mentioned technical proposal, muffler is configured with negative pressure generator.
By above-mentioned technical proposal, the vacuum meter that head cavity is connected is configured with head.
By above-mentioned technical proposal, PE material spray equipments are configured with head cavity, for making PE material in vacuum environment
Lower uniform adsorption forms thin-walled on cable core surface.
By above-mentioned technical proposal, the jet pipe of the negative pressure generator is connected with the rear tube of head.
It is -0.2Mpa-0Mpa in the range of negative pressure of the generation of head cavity during work by above-mentioned technical proposal.
Having the beneficial effect that acquired by the utility model：
1st, the utility model obtains being suitable for the molding vacuum environment of micro- cable by controlling the air inflow of negative pressure generator,
So that the uniform absorption of PE material on cable core surface, controls the diameter of micro- cable, have simple in structure, it is reasonable to set, easy to operate, and
It is applied in actual production, ensure that the stability of product diameter, further increases the quality of product.
2nd, the utility model controls air inflow by pneumatic triple piece, precise pressure regulating valve, obtains continuously adjustable vacuum
Degree, changes the nonadjustable problem of traditional mode of production mode vacuum, ensure that micro- cable production diameter stability.
3rd, package unit is furnished with muffler, will not produce noise powerful in vacuum process, and complete component cost is low, exempts to tie up
Shield, is that a kind of utility model for being exclusively used in micro- cable production creates device.
Brief description of the drawings
Fig. 1 is the structure chart of the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of continuously adjustable device of vacuum for micro- cable production is present embodiments provided, including machine
Frame, is equipped with negative pressure generator 4 in rack, and the entrance of the negative pressure generator 4 is connected by air inlet pipeline with source of the gas 1, outlet
It is connected by jet pipe with the rear tube 6 of head cavity, the entrance of micro- cable cable core 9 from head 7 stretches into, and is pierced by from exit,
The inlet and outlet of head with 8 seal arrangement of cable core.PE material spray equipments are configured with head cavity, for expecting PE
Uniform adsorption forms thin-walled on cable core surface under vacuum environment.Negative pressure generator in the utility model is high using jet pipe
Speed injection compressed air, jet stream is formed in nozzle exit, is produced volume and is inhaled flowing, under Involving velocity so that around nozzle exit
Air be constantly sucked away, the pressure in adsorbent chamber is down to below atmospheric pressure, formed certain vacuum degree a kind of device.
The a diameter of 6-10 ㎜ of micro- cable in the utility model, in order to further ensure the stability of micro- cable diameter, are connected
Continue adjustable vacuum, pneumatic triple piece and pressure regulator valve 2 are equipped with air inlet pipeline, the source of the gas 1 connects pneumatic triple piece, institute
Pneumatic triplets are stated with pressure regulator valve 2 to be connected.
In the utility model, muffler 3 is configured with negative pressure generator 4, will not so be produced in process of production true
Powerful noise in null process, complete component cost is low, non-maintaining, highly practical.
When cable core 8 passes through head 7, inlet and outlet forms certain sealing function, and negative pressure generator 4 is in source of the gas tune at this time
Start that head cavity is carried out to vacuumize action under the action of section, the range of negative pressure that negative pressure generator 4 produces can just match
The shaping environment of micro- cable PE material, negative pressure it is too big or it is too small be all unfavorable for vacuum sizing, and be furnished with precise vacuum table 5, can monitor
Vacuum magnitude, it is preferred that in the range of negative pressure of the generation of head cavity be -0.2Mpa-0Mpa.Cable core 8 and PE material spray equipments
The PE of ejection expects that under the action of vacuum the uniform absorption of PE material forms thin-walled on cable core surface, and has certain lines, can
Promote cable core 8 to travel forward in air-blowing construction, micro- cable 9 is formed after having gone out the exit of head 7.
