Description
Technical field
It is specifically a kind of paper mould grouting device that the utility model, which designs paper mould technical field,.
Background technique
Paper mould is a kind of three-dimensional paper technology.It is moulded on mould machine by certain moduli tool using waste paper as raw material
The paper products of certain shapes out.It has four big advantages: raw material is waste paper, including paperboard, litter decoration paper, useless white edge paper etc., is come
Source is extensive；Its manufacturing process is completed by processes such as slurrying, adsorption forming, dryness finalizations, environmental sound；It can be with reclaiming benefit
With；Volume ratio foamed plastic is small, can be overlapped, and communications and transportation is convenient.It is slow more to do industry in addition to making cutlery box, tableware for paper mould
Punching packaging, development is very rapid at present.Production paper mould technical equipment have developed rapidly, and basic craft course includes that raw material is beaten
Slurry, ingredient, compression molding, drying, sizing.
In paper mould manufacturing process, to improve production efficiency, multiple product once grouting moldings are generallyd use.One
In mould multiple products in each slip casting mould grouting amount control, be that slip casting weight is freely distributed by vaccum pulp absorbing by unified slurry storage bucket
's.This grouting amount control mode is difficult to ensure the consistency of each product weight, therefore molds the multiple products of a mould in midge
In production, it may appear that with the big defect of a batch product weight deviation, such as cause product became uneven, thick waste material is thin
It can't meet the quality requirement.Also have using monomer slip casting, however use monomer slip casting, though advantageously account for above-mentioned weight unevenness
Technical problem, but production efficiency is greatly reduced, and energy consumption increases, so that production cost increases substantially.Therefore, a mould multiple products
The control of injection forming weight is always a great problem in paper mould production.
In addition, slurry does not have a mixing plant in slurry storing tank, slurry is placed after a certain period of time, the slurry in slurry storing tank on to
Under have concentration difference, even if the amount of slip casting is consistent, it is also possible to the inconsistent situation of each product thickness occur.
Utility model content
The utility model aim is intended to provide a kind of paper mould grouting device, it is ensured that each mould in a mould mostly system
The grouting amount of chamber is consistent, and the concentration of slurry is consistent, to improve the quality of product.
To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
A kind of paper mould grouting device, including slurry storing tank and several slip casting buckets, the bottom of the slurry storing tank offers
Several grout outlets, upper part offer pulp inlet, and the number of the grout outlet is identical as the number of the slip casting bucket；It is described go out
Slurry mouth passes through connecting tube respectively and is connected to the bottom of corresponding slip casting bucket, and the bottom of the slip casting bucket is also communicated with Grouting Pipe, described
Connecting tube is provided with the first check valve close to that one end of slip casting bucket, and the Grouting Pipe is arranged close to that one end of the slip casting bucket
There is second one-way valve, first check valve and second one-way valve are in a unlatching, a state closed always；The note
It is provided with piston in slurry bucket, hydraulic cylinder is provided at the top of the slip casting bucket, the hydraulic stem of the hydraulic cylinder passes through the slip casting
The top of bucket is fixedly connected in the piston.
Utility model by adopting the above technical scheme, when initial state, piston is located at the bottom of slip casting bucket, piston and slip casting
The bottom of bucket is in vacuum state, opens the first check valve, starts hydraulic cylinder, so that piston moves up, will be stored up by negative pressure
Slurries are drawn into slip casting bucket in slurry bucket, after piston motion to predeterminated position, are closed hydraulic cylinder, are then opened second one-way valve,
It is again started up hydraulic cylinder, piston moves downward, moves to initial position, and slurry all in slip casting bucket is injected by Grouting Pipe
Into die cavity.The slurries in slurry storing tank are drawn into slip casting bucket so that forming negative pressure inside slip casting bucket by the movement of piston
In, to guarantee that the grouting amount injected in each die cavity is consistent；It needs to inhale to control by controlling the distance of piston motion simultaneously
The number of slurry entered.
It further limits, the slurry storing tank bottom is equally divided into several areas by partition by the bottom of the slurry storing tank
Domain, the number in the region of division is identical as the number of the grout outlet, be at the top of each region it is interconnected, bottom is equal
Offer grout outlet.
Because grout outlet is arranged at the bottom of slurry storing tank, for the influence between reducing, set in the bottom of slurry storing tank
Partition is set, bottom is averagely divided into several regions.And in order to guarantee pulp inlet injection slurry storing tank slurries can uniformly into
Enter to each region, interconnected structure will be set as between the top of region.
It further limits, further includes return-flow structure, the return-flow structure includes several return pipes, pump, the slurry storing tank
Each region of bottom offers bypass outlet, and the top of the slurry storing tank is corresponding with the bypass outlet to be provided with back
Inflow entrance, the both ends of the return pipe are connected to the bypass outlet and reflux inlet.
Slurries are stored after a certain period of time in slurry storing tank, it is more likely that a concentration difference from top to bottom are occurred, and flowed back
The slurries of slurry storing tank bottom are drawn at the top of slurry storing tank by structure by pump, are re-mixed, and guarantee that slurries are dense in slip casting bucket
The consistency of degree.
It further limits, the slurry storing tank is cylinder, and the reflux inlet is respectively positioned on same circumference, and inclination is set
It sets, and angle of the tangent line of each reflux inlet and circumference with corresponding reflux inlet is acute angle, and each is returned
The inclined direction of inflow entrance is clockwise or counter-clockwise.
Reflux inlet is arranged around circumference tilt, so that the slurries flowed out from reflux inlet are according to the clockwise or inverse time
Needle flowing is conducive to generate whirlpool, can further eliminate the concentration difference of slurries.
It further limits, the pulp inlet and the reflux inlet are located on same circumference, and are obliquely installed, and pass back into
The inclined direction of mouth is consistent.
Equally, the setting by pulp inlet as reflux inlet, purpose also for eddy flow is generated, by bottom slurry and
Top slurry is sufficiently mixed.
