Abstract

The utility model relates to a special feeding truck for a greenhouse film extruder, which belongs to the technical field of multilayer coextrusion blow molding and comprises an open carriage and wheels arranged at the bottom of the carriage, wherein the bottom of the carriage is provided with a discharge opening at which a drawing gate is arranged. When in use, the discharge opening of the feeding truck is rightly opposite to a feed inlet of a feed delivery pipe; and raw materials in the carriage fall from the discharge opening after being opened, slide to materials of the extruder through the feed delivery pipe and are further plasticized and extruded in the extruder. Master batches and auxiliary materials which are evenly mixed and carried by the feeding truck cannot be layered, so the quality of the extruded finished products can be ensured.

Description

The special use of canopy film extruder adds truck

Technical field

The utility model belongs to agricultural film extruder accessory technical field, relates to the trolley that adds that uses on a kind of multi-layer co-extruded machine.

Background technology

Existing multi-layer co-extruded compound blowing production technology, usually after the masterbatch that will prepare in advance below the machine and auxiliary material mix, be pumped to aspiration pump in the charge door of extruder frame top, pellet by deadweight by the conveying pipeline landing of frame top to extruder barrel, and then in extruder, plastify and extrude.

There is following defective in the mode of this conveying plastic granule: because the density of masterbatch and auxiliary material is different, aspiration pump is when extracting raw material, the transporting velocity of masterbatch and auxiliary material is also inequality, the big person's speed of density is slower, the little person's speed of density is very fast, thereby causes the pellet layering that falls into extruder barrel, and it is inhomogeneous that raw material is mixed, finally cause extruded product mass defect, fall flat.

The utility model content

When using the aspiration pump pump in stock for solving existing multi-layer co-extruded compound blowing production technology, masterbatch that causes and auxiliary material mix uneven problem, and the utility model provides the special use of a kind of canopy film extruder to add truck, and its embodiment is as follows:

The special use of canopy film extruder adds truck, this adds the wheel that truck comprises uncovered compartment, is installed in the pushing hands on the railway carriage and is installed on the bottom, compartment, the funnel shaped that the bottom, compartment is square, its discharging opening place is equipped with the drawing and pulling type flashboard, the flashboard front end has one and leaks the material mouth, there is the switch control elbow of a downward bending flashboard rear end, and the bending that makes progress of flashboard front end is equipped with the return spring of a flashboard between last bending and go-cart curb girder.

In multi-layer co-extruded compound blowing is produced, the plastic granule for preparing in advance and mix can be packed into and add in the truck, to add truck by lift winches on the framework platform that is positioned at the extruder top, wheel by the bottom, compartment pushes to the conveying pipeline top with it, make and add the charging aperture of truck discharging opening over against conveying pipeline, this moment, the elbow of flashboard below kept off on the retaining head of installing at canopy film extruder charging aperture front end, the retaining head brake that will feed in raw material pushes away behind the door, make the leakage material mouth of flashboard front end be positioned at the discharging opening middle part, discharging opening is opened, raw material in the compartment promptly falls from discharging opening, fall into the charging aperture of extruder material pipe top, pellet through the conveying pipeline landing to extruder material pipe; Behind reinforced the end, truck is drawn back, at this moment, return spring draws before with flashboard, closes discharging opening.Thisly add the plastic granule that truck transports with special-purpose, masterbatch and auxiliary material mix, can not guaranteed the extruded product quality by layering; The control of the switch of feed opening is simple and convenient in addition.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Fig. 1 is a structural representation of the present utility model;

The specific embodiment

Embodiment: as depicted in figs. 1 and 2, the special use of canopy film extruder adds truck, this adds the wheel 8 that truck comprises uncovered compartment 1, is installed in the pushing hands 2 on the railway carriage 1 and is installed on 1 bottom, compartment, the funnel shaped that 1 bottom, compartment is square, its discharging opening 9 places are equipped with drawing and pulling type flashboard 4, and flashboard 4 front ends have one and leak material mouth 6; There is the switch control elbow 15 of a downward bending flashboard 4 rear ends, and the bending that makes progress of flashboard 4 front ends is equipped with the return spring 7. of a flashboard 4 between last bending and go-cart curb girder

In multi-layer co-extruded compound blowing is produced, the plastic granule 3 for preparing in advance and mix can be packed into and add in the truck compartment 1, to add truck by lift winches to and is positioned on the workbench 10 that extruder goes out conveying pipeline 11 tops, stack pallet is pushed to charging aperture 14 tops of conveying pipeline 13, make and add truck discharging opening 9 over against charging aperture 14, this moment flashboard 4 belows elbow 15 retainings on a retaining that charging aperture 14 front ends of canopy film extruder are installed 5, retaining 5 brake plate 4 pushers that will feed in raw material, leak material mouth 6 on the flashboard 4 and be pushed to discharging opening 9 middle parts, discharging opening 9 is opened, raw material in the compartment promptly falls from discharging opening 9, pellet through conveying pipeline 13 landings to extruder material pipe 12; Behind reinforced the end, truck is drawn back, at this moment, return spring 7 draws before with flashboard 4, closes discharging opening 9.

Claims

1. the special use of canopy film extruder adds truck, this adds the wheel (8) that truck comprises uncovered compartment (1), is installed in the pushing hands (2) on the railway carriage (1) and is installed on bottom, compartment (1), it is characterized in that: the funnel shaped that compartment (1) bottom is square, its discharging opening (9) locates to be equipped with drawing and pulling type flashboard (4), has one on the flashboard (4) and leaks material mouthful (6).

2. canopy film extruder as claimed in claim 1 special use adds truck, it is characterized in that: there is the switch control elbow (15) of a downward bending flashboard (4) rear end, the bending that makes progress of flashboard (4) front end is equipped with the return spring (7) of a flashboard (4) between last bending and go-cart curb girder.
