Abstract

The utility model relates to a multi-functional recovery granule-making machine for a plastic film. The utility model is composed of a charging barrel, a machine frame, and a power wheel, wherein, the inner part of the charging barrel is provided with a movable blade, a fixed blade, and a rubbing blade. The utility model is characterized in that the upper part of the movable blade is coaxially provided with a rough cut movable blade which is used for tearing. A shaft lever is provided with a sealing ring. The outer side of the wall of the charging barrel is added with a holding and heating baffle plate. Both sides of the charging barrel are provided with screw type plastic extruders. The discharge holes of the extruders are provided with stripe-shaped granular material molding filter screens. The utility model has the advantages that the performance of a recovery granule-making machine for a plastic film is improved, the melting stock of the charging barrel directly enters into the plastic extruder and does not need to be stored, and compact stripe-shaped granular materials can be extruded directly, and the quality of the granulation is improved. The utility model is suitable for crush molding and granulating molding for waste plastics and plastic films.

Description

The multifunctional plastic film reclaims comminutor

The utility model belongs to the processing of plastic of using, particularly a kind of machinery of pulverizing plastics and granulation that is specifically designed to.

At present, the use of plastic sheeting more and more widely, a large amount of waste or used plastics pollute utilization extremely to be recycled to environment.As high and low pressure polyethylene film, poly-third vinyl film, braid over braid, PVC thin-film sheet, PS polystyrene, foam slippers, mess-tin etc., need to reclaim pulverizing, granulation, reshaping is made various suitable products.Chinese patent " the one-step method plastic sheeting reclaims grain-making machine " the 94201937.7th, a kind of novel plastic sheeting reclaims comminutor; utilize the friction blade to drive the material of chopping and the friction between material tube inner wall; heat taking place in barrel the temperature in the barrel is raise, the plastic sheeting that is cut into fragment can be plastified into graininess.Handling safety, easy, the reworked material water content is low, the quality height.But, plastifying into short grained particle from the discharging opening ejection, the surface is fine and close inadequately smooth, still need improve.

The purpose of this utility model is, designs a kind of multi-functional plastic sheeting and reclaims comminutor, and it is combined integrated cleverly with the screw plastic extruder that the one-step method plastic sheeting is reclaimed comminutor, makes the bar shaped pellet densification gloss of extruding, better quality.

Multifunctional plastic film of the present utility model reclaims comminutor, be made up of barrel, frame, power wheel, the barrel top is a charging aperture, and the below is provided with sprays discharging opening and impurity outlet, be provided with ledger-plate in the barrel, cutting blade, the friction blade is characterized in that, above cutting blade coaxial, be provided with the rough lumber cutting blade that tears waste or used plastics, establish the axostylus axostyle sealing ring at cutting blade rotating shaft root, establish elongated material-blocking plate between cutting blade and friction blade, barrel barrel periphery adds insulation heating coaming plate; In the barrel both sides two parallel screw plastic extruders are set, offer the feeding port that leads to extruder in the barrel bottom, the discharging opening place of extruder is provided with the push-and-pull slide type and changes filter screen fast.

Using method of the present utility model is that waste plastic film is dropped into barrel, after the rough lumber cutting blade tears fragmentation, precession blade chopping again, fall into friction blade top, stir down at elongated material-blocking plate, the friction cutter through rotating presses to the barrel barrel with particle and carries out frictional heat, the heating of the resistance heated coaming plate of barrel periphery simultaneously, insulation makes the barrel internal temperature rise, the particle fusing, under centrifugal action, eject into pellet by spraying discharging opening;

For the deep processing pellet, the particle of fusing can be guided to the extruder feeding port, under the long screw propulsion rod of extruded stock promotes, be the bar shaped material by the discharging opening place of extruder by filter screen and extrude, again through cooling, the cut-out of routine, the pellet of one-tenth short cylindrical.

The utility model has the advantages that, set up the rough lumber cutting blade, can discerp the Polypropylence Sheet of bulk, be beneficial to and pulverize and granulation; The rotating shaft root is established the axostylus axostyle sealing ring, can prevent that powder from entering bearing; The resistance that barrel installs additional is protected the electric heating coaming plate, and the temperature that can improve the friction plate position reaches 200 ℃, utilizes plastics flour fusing granulation; The melting charge of barrel directly enters the screw plastic extruder, can store, and directly extrudes fine and close bar shaped pellet; The slide type filter screen is convenient to quick replacing, and uninterrupted granulation is applicable to pulverizing, the granulation of plastic sheeting, waste or used plastics.

Below in conjunction with drawings and Examples, the utility model is further described.

Fig. 2 is the A-A profile of Fig. 1;

Fig. 3 is the B-B profile of Fig. 1;

Fig. 4 is a push-and-pull slide type filter screen organigram.

As seen from the figure; the multifunctional plastic film reclaims comminutor; by barrel 1; frame 2; power wheel 3 is formed; the barrel top is a charging aperture 4; the below is provided with sprays discharging opening 5 and impurity outlet 6; be provided with ledger-plate 7 in the barrel; cutting blade 8; friction blade 9; it is characterized in that; above cutting blade coaxial, be provided with the rough lumber cutting blade 10 that tears waste or used plastics; establish axostylus axostyle sealing ring 11 at cutting blade rotating shaft root; between cutting blade and friction blade, establish elongated material-blocking plate 12; barrel barrel periphery adds insulation heating coaming plate 13; in the barrel both sides two parallel screw plastic extruders 14 are set, offer the feeding port 15 that leads to extruder in the barrel bottom, the discharging opening place of extruder is provided with the push-and-pull slide type and changes filter screen 16 fast.
