Abstract
The utility model provides a composite packaging bag raw materials foaming device is moulded to paper utensil, includes that one has a mould case that the chamber is held in the foaming, the chamber is held in the foaming can be for circular or square structure, be equipped with feed inlet and discharge gate on the mould case the foaming is held the intracavity and is connected with the piston rod, piston rod one end is connected to the pneumatic cylinder, and the other end is connected with the increased pressure board, the increased pressure board contacts with the inner wall that the chamber is held in the foaming increased pressure board the edge is equipped with the sealing washer, and this sealing washer adopts the heat proof material of the expandable that is heated to make, and the thermal expansion in carrying out extrusion process to the fuse -element forms sealedly, be provided with the air bleeding valve on the increased pressure board, when pressure reached a definite value, the air bleeding valve was opened, prevented that the mould case from taking place to burst the phenomenon, the mould incasement still is equipped with electric heater unit, can heat the fuse -element of foaming appearance intracavity, prevents that the fuse -element from solidifying, be equipped with the cooling pipe on the mould case outer wall, can carry out cooling treatment to the fuse -element in needs.
Description
Technical field
The utility model relates to foam device technical field, is specifically related to a kind of paper plastic combined package bag raw material foam device.
Background technology
Polywoven Bag, also known as woven bag, is widely used in a kind of packaging material of the article such as fertilizer, chemical products a few days ago.Plastics stretch tight and knit bag and be configured to Polypropylene Bag, Polythene Bag by main material system; Be divided into seam end bag by method of sewing, compile bag at the bottom of limit.The production technology of Polywoven Bag utilizes plastic raw materials to be flat filament through extrusion film, cutting, simple tension, through obtaining product through knitting device.Because braiding have employed crisscross transmission, woven bag is provided with and good draw resistance and anti-ly pierce through performance, but its table and uneven, not only have impact on the outward appearance of Total Product, and the dim design of printing from the teeth outwards.In order to make the surfacing of woven bag, printed patterns is clear, attractive in appearance, is coated with one deck again moulds plastic sheeting on the surface of woven bag, is thisly referred to as composite plastic woven bag.
Existing braided bag production line needs when producing composite plastic woven bag to improve, to adapt to this new joint product.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of easy to operate, steady quality reliable paper plastic combined package bag raw material foam device.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of paper plastic combined package bag raw material foam device tool, comprise the die box that has foaming cavity volume, described foaming cavity volume can be circular or square structure, for holding flux foaming material, described die box is provided with charging aperture and discharging opening, piston rod is connected with in described foaming cavity volume, described piston rod one end is connected to hydraulic cylinder, the other end is connected with increased pressure board, described increased pressure board contacts with the inwall of foaming cavity volume, sealing ring is provided with in described increased pressure board edge, sealing circle adopts the expandable heat proof material that is heated to make, expanded by heating in extrusion process is being carried out to melt, form sealing, described increased pressure board is provided with air bleeding valve, and when pressure reaches certain value, air bleeding valve is opened, and prevents die box generation Decrepitation Phenomena, in described die box, be also provided with electric heater unit, the melt in foaming cavity volume can be heated, prevent melt solidifying, described die box outer wall is provided with cooling pipe, cooling processing can be carried out to melt when needs.
Described die box outer setting has incubator, can be incubated the melt foamed, and releases melt and enter molding procedure when needs.
The beneficial effects of the utility model are: the utility model device structure is simple, novel in design, supercharging mode is adopted to foam, reduce bubble floating, the uniformity of foamed melt density can be kept, guarantee uniform in foaming, improve product percent of pass, overcome conventional melt foaming and to foam uneven problem.
