According to the expandable polyethylene extruder, materials are conveyed by utilizing the conveying cylinder and are extruded by utilizing the gear pump, and the storage cylinder is arranged between the conveying cylinder and the gear pump, so that the expandable polyethylene extruder has the advantages of stable processing process and high continuity, the expandable polyethylene coiled materials with consistent density and uniform air bubbles can be produced.
Description
Technical field
The utility model relates to the processing mechanical apparatus technical field, the cotton gear pump extruder of particularly a kind of pearl.
Background technology
The pearl cotton is claimed EPE (Expandable Polyethylene) again; Adopting the low density polyethylene (LDPE) ester to produce countless separated foams through physical blowing constitutes; It has overcome the shortcoming of frangible, the yielding and recovery difference of common foamed glue; Have water proof protection against the tide, shockproof, sound insulation, insulation, plasticity is good, toughness is strong, capable of circulationly reproduce, plurality of advantages such as power is strong are hit in environmental protection and anti-; Also has good chemical resistance; The ideal that is the Traditional Packing material substitutes device, is widely used in the packing of multiple products such as electronic apparatus, instrument and meter, computer, sound equipment, medicine equipment, industry control toy, lamp decoration, workmanship, glass, pottery, household electrical appliances, spraying, furniture, drinks and gift wrap, hardware, toy, melon and fruit, the inner packing of leather shoes, daily device.After adding the antistatic agent fire retardant, more show its remarkable performance.
At present on the market the cotton extruder of pearl adopts screw mechanism mostly, and the rotation through screw rod is pressed into the pearl cotton of liquid state in the slit between the screw thread on the screw rod, again the finished product after shaping area output extruding.It has the big advantage of thrust the cotton extruder of above-mentioned existing pearl, can produce the bigger pearl lap material of density.But its flow is less, extrudes instability, can't guarantee continuous at the uniform velocity extruding, thereby is easy to generate density unevenness, the finished product that outward appearance is not good, and production capacity is also low.
The utility model content
The main purpose of the utility model is, to above-mentioned deficiency of the prior art, provides a kind of pearl cotton gear pump extruder, and it has the production capacity height, can be continuously, stably produce high-quality, the pearl lap material of thickness greatly.
For realizing the foregoing invention purpose, the utility model adopts following technical scheme.
The cotton gear pump extruder of the pearl that the utility model provides; Comprise the feeding tube, material storage tube, gear pump and the moulding delivery outlet that are linked in sequence successively; Said feeding tube is input to the pearl cotton of liquid state in the said material storage tube, and said gear pump will output to said moulding delivery outlet after will being stored in the cotton extruding of said pearl in the said material storage tube.
Preferably, be provided with screw rod in the said feeding tube, said pearl cotton is released by said screw rod and is sent to said material storage tube.
Preferably, said feeding tube is outside equipped with attemperator.
Preferably, said gear pump comprise two each other near gear, and two said gear velocities of rotation are identical, in the opposite direction.
Preferably, two said gears drive uniform rotation by same drive motors.
Than above-mentioned prior art, the utlity model has following beneficial effect:
The utility model utilizes feeding tube to carry out feeding; Gear pump pushes; And the design of material storage tube is set between feeding tube and gear pump, and have that process is stable, a continuity advantage preferably, can produce consistent in density, the uniform pearl lap of bubble material.In addition,, need not to apply simultaneously high thrust, therefore can reach higher flows, thereby can produce the pearl lap material of thickening type, satisfy diversified production demand because the feeding tube of the utility model is only controlled the cotton flow of pearl.
Description of drawings
Fig. 1 is the structural representation of the cotton gear pump extruder of pearl among the utility model embodiment;
Fig. 2 is the utility model embodiment middle gear pump structure sketch map.
The realization of the utility model purpose, functional characteristics and advantage will combine embodiment, further specify with reference to accompanying drawing.
The specific embodiment
Below will combine accompanying drawing and specific embodiment to specify the technical scheme of the utility model, so as clearer, understand the invention essence of the utility model intuitively.
Fig. 1 is the structural representation of the cotton gear pump extruder of pearl among the utility model embodiment; Fig. 2 is the utility model embodiment middle gear pump structure sketch map.
Shown in seeing figures.1.and.2; Present embodiment provides a kind of pearl cotton gear pump extruder; It comprises feeding tube 1, material storage tube 2, gear pump 3 and moulding delivery outlet 4 etc., and above-mentioned feeding tube 1, material storage tube 2, gear pump 3 and moulding delivery outlet 4 are linked in sequence successively, are input in the material storage tube 2 by the pearl cotton pulp material of feeding tube 1 with liquid molten; To be stored in the pearl cotton pulp material extruding in the material storage tube by gear pump 3 then; And output to moulding delivery outlet 4 places, behind the cooling and shaping, be pearl lap material finished product.
Particularly, be provided with screw rod (not shown) in the feeding tube 1, feeding tube 1 is outside equipped with attemperator 11, is used to the insulation of pearl cotton pulp material.Slit between the screw thread of pearl cotton pulp material on screw rod is pressed in the material storage tube 2; Gear pump 3 comprises two gears 5 that lean on very closely each other; These two gear 5 velocities of rotation are identical, in the opposite direction, in rotation process, in material storage tube 2, draw pearl cotton pulp material; After extruding, export by the moulding delivery outlet.In the whole process; The effect of material storage tube 2 is to serve as buffering area, and the influence that the velocity perturbation that produces when avoiding feeding tube 1 to carry slurry produces extrusion process is to guarantee the continuity and the stability of production process; Thereby pearl lap material density and thickness are consistent, and outward appearance is preferable.
As preferred version, above-mentioned two gears 5 are driven at the uniform velocity synchronously by same drive motors 6 and rotate.Thereby in process of manufacture, gear pump 3 can continuously, stably be produced high-quality pearl lap material.
Certainly, the feeding tube 1 of present embodiment can not adopt screw rod yet and directly through pipeline pearl cotton pulp material is input in the material storage tube 2, at this moment; The flow of pearl cotton pulp material can reach very big, and when needs were produced the pearl lap material of thickening type, the rotation that only needs to improve two gears 5 got final product; Very convenient, up to the coiled strip that processes suitable depth, therefore; When carrying out the conversion of thick material and thin material processing technology, seem very flexible.
In sum; The utility model utilizes feeding tube 1 to carry out feeding, and gear pump 3 pushes, and between feeding tube 1 and gear pump 3, the design of material storage tube 2 is set; Have that process is stable, continuity advantage preferably, can produce that density is even, the uniform pearl lap of bubble material.In addition,, therefore can reach higher flows, thereby can produce the pearl lap material of thickening type, can satisfy diversified production demand because the cotton flow of 1 control of the feeding tube of the utility model pearl need not to apply simultaneously high thrust.
The above is merely the preferred embodiment of the utility model; Be not so limit its claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
