Abstract
The utility model belongs to the technical field of a cushion, and relates to a hollow plastic thread cushion and its production device. The hollow plastic thread cushion comprises plastic flosses which are arranged randomly and are mutualy connected, the plastic floss is a hollow plastic hose. The production device for the hollow plastic thread cushion comprises two plastic extruding machines connected with a feed inlet of an multiple-hose extruding mold, and a forming device, a cooling and shaping device, a towing mechanism and a cutting device which are arranged in sequence. The utility model has the advantages tht the hollow plastic thread cushion has good elasticity, light weight, low cost, good air permeability, easy washing and comfortable sitting and sleeping, the hollow plastic thread cushion produced by the production device is suitable for producing various products such as the cushion, the back cushion, the bed mattress and the like.
Description
Technical field
The utility model belongs to a cushion technical field, refers in particular to a kind of hollow plastic silk cushion and production equipment thereof.
Background technology
Traditional elastic cushion is that its weak point is by the plastics silk production of steel wire, spring, sponge and real core: the one, and the weight of the product that real core plastics sleave is made is big, and consumption of raw material is many, the product cost height; The 2nd, the poor flexibility of the plastics sleave of real cored structure, comfortableness is poor.
Summary of the invention
The purpose of this utility model provides a kind of good springiness, viscosity is good, in light weight, cost is low, good permeability, easy cleaning, seat crouch comfortable hollow plastic silk cushion and production equipment thereof.
The purpose of this utility model is achieved in that
Hollow plastic silk cushion comprises lack of alignment and the plastics sleave of tie point is arranged each other that described plastics sleave is the plastic flexible pipe of hollow.
Above-mentioned plastic flexible pipe is made with EVA, LDPE plastic material.
The production equipment of hollow plastic silk cushion includes two plastic extruders and is connected with the charging aperture of one many flexible pipe extrusion dies, is disposed with shaped device, cooling and shaping device, draw-gear and cutter sweep afterwards.
The outstanding compared to existing technology advantage of the utility model is:
1, the good springiness of hollow plastic silk cushion of the present utility model, viscosity is good, in light weight, cost is low, good permeability, easy cleaning, seat crouch comfortable;
2, the hollow plastic silk cushion suitable for making with device fabrication of the present utility model becomes products such as various cushions, back cushion, mattress.
Description of drawings
Fig. 1 is a partial sectional view of the present utility model;
Fig. 2 is the cutaway view of hollow plastic sleave of the present utility model;
Fig. 3 is the structure diagram of production equipment of the present utility model.
The specific embodiment
With specific embodiment the utility model is further described below, referring to Fig. 1-:
Hollow plastic silk cushion 1 comprises lack of alignment and the plastics sleave 90 of tie point is arranged each other that described plastics sleave 90 is the plastic flexible pipe of hollow 901.
Above-mentioned plastic flexible pipe 90 is to make with EVA, LDPE plastic material.
The production equipment of hollow plastic silk cushion, including two plastic extruders 10 is connected with the charging aperture of one many flexible pipe extrusion dies 30, the outlet that is every plastic extruder 10 is connected with the charging aperture of one many flexible pipe extrusion dies 30, is disposed with shaped device 40, cooling and shaping device 50, draw-gear 60 and cutter sweep 70 afterwards.
Production technology of the present utility model is: plastic matrix EVA and LDPE are mixed a charge door 20 addings of back from the production equipment of hollow plastic silk cushion, single plastic matrix LDPE is added from another charge door 20 of the production equipment of hollow plastic silk cushion, the starting device power supply, heating plasticizing formation melt shape in plastic extruder 10 after, two groups of material that two charge doors 20 add enter in the many flexible pipe extrusion dies 30, and be extruded into the tubular plastic sleave 90 of mesopore from the discharging opening of many flexible pipe extrusion dies 30, tubular plastic sleave 90 is subjected to the restriction of shaped device 40, in the thickness that limits, intersect, because the temperature of the discharging opening of many flexible pipe extrusion dies 30 is higher, plastics sleave 90 is bonding mutually at the crossing place, under the traction of draw-gear 60, the semi-finished product that shaped device 40 molds in cooling device 50 behind cooling and shaping, draw-gear 60 draws to cutter sweep 70 places and cuts into the size that needs, and is transported on the work top 80 to package spare.
The utility model adds the adhesive property that EVA can improve plastics sleave 90 in masterbatch base-material LDPE, the tubular plastic sleave 90 of hollow 901 has better elastic performance, make the hollow plastic silk cushion 1 produce good springiness, that viscosity is good, in light weight, cost is low, good permeability, easy cleaning, seat crouch is comfortable, suitable for making becomes products such as various cushions, back cushion, mattress.
The foregoing description only is one of preferred embodiment of the present utility model; be not to limit protection domain of the present utility model according to this; so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
