Abstract

The utility model relates to a sieving type plastic recovering machine. A vibration sieve hopper is also arranged right below a sieve of a crushing chamber, and the vibration sieve hopper is driven by a horizontal reciprocating motion mechanism; the bottom of the vibration sieve hopper is provided with plane sieve, one side of the vibration sieve hopper is provided with an opening at the part adjacent to the lower end of the sieve thereby, and the opening of the vibration sieve hopper is in alignment with a feed port of a recovered material chamber; an opening hopper used for collecting dust is also arranged right below the vibration sieve hopper. The utility model enables powder and dust to be not contained in recovered plastic particles; thus a cleaner can not be clogged, and the operation of the recovering machine can not be affect, which is favorable to ensuring the effect of the surface appearances of plastic products made of the recovered plastic particles.

Description

Sieve powder formula plastics recovery machine

Technical field

The utility model belongs to the plastics machinery technical field, is specifically related to a kind of sieve powder formula plastics recovery machine.

Background technology

In the plastic products process of manufacture, can produce a large amount of leftover pieces, these leftover pieces can be collected by the plastics recovery machine that is placed on the device of plastic processing next door, and in its crushing chamber, stir by stirring knife up speed, be ground into particle, crushing chamber bottom is provided with screen cloth, makes to pulverize the particle that obtains and just can fall into down automatically into the reclaimed materials chamber after less than screened port, sends device of plastic processing back to by air blast then and utilizes again.Existing plastics recovery machine is sent back in the plastic grain of device of plastic processing, also can be embedded simultaneously powder and the space dust that produces in a large amount of crushing process, bring the problem of two aspects thus, the first can badly influence utilizes these to reclaim the appearance effect of the prepared plastic products of plastic grain, reduces its brightness; It two is that powder and dust also can stop up cleaner gradually and influence the work of plastics recovery machine.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of sieve powder formula plastics recovery machine is provided, and it can make and not contain powder and dust in the plastic grain that is recovered to substantially.

Its purpose can realize by following scheme: this sieve powder formula plastics recovery machine comprises crushing chamber and reclaimed materials chamber, the crushing chamber bottom is provided with fixed grit, its main feature is, under the screen cloth of crushing chamber, also be provided with the vibratory sieve bucket, the vibratory sieve bucket is driven by a horizontal reciprocating movement mechanism, vibratory sieve bucket bottom is provided with the screen cloth of flat shape, and the screen cloth of vibratory sieve bucket is the lower heeling condition of the higher other end of an end; The vibratory sieve bucket is provided with opening in the side near its screen cloth low side, and the opening of vibratory sieve bucket is aimed at the charging aperture in reclaimed materials chamber; Under the vibratory sieve bucket, also be provided with the uncovered bucket that is used to collect dust.

Realization above-mentioned purpose scheme preferably is: the opening of vibratory sieve bucket is arranged near on the sidewall of its screen cloth low side.

Realize that the better scheme of above-mentioned purpose is: described horizontal reciprocating movement mechanism is a toggle.

The stirring cutter of toggle and crushing chamber can be by same motor-driven.

It is vertical that the direction that best and vibratory sieve bucket straight line move back and forth is moved towards in the inclination of vibratory sieve bucket screen cloth.So-called " the inclination trend of vibratory sieve bucket screen cloth " is meant by the higher-end of vibratory sieve bucket screen cloth and points to direction than low side.

The aperture of vibratory sieve bucket screen cloth is preferably 1mm～3mm less than 6mm.

The angle of inclination of vibratory sieve bucket screen cloth can be 1 °～10 °, is preferably 2 °～4 °.

Described vibratory sieve bucket can be drawer type, is convenient to change the vibratory sieve bucket of different mesh sizes like this, to adapt to the needs of different condition.

The utlity model has following advantage and effect:

1, plastic leftover bits is after pulverizing chamber is crushed to less than the particle that sets value; fall to the vibratory sieve bucket under can be from the fixed grit of pulverizing chamber vertical; the quick level of vibratory sieve bucket is vibrated back and forth; powder that is embedded in the particle and dust can be in vibration processes screened separating; and under the screen cloth of vibratory sieve bucket, fall to uncovered bucket; other particle is then in vibration processes; slip down gradually along the screen cloth that tilts a little; slip out and fall into the charging aperture in reclaimed materials chamber until opening, finally blow back device of plastic processing by the air blast in the reclaimed materials chamber from the vibratory sieve bucket.Therefore, do not contain powder and dust substantially in the particle that the utility model reclaims, avoid stopping up cleaner and influence the work of recovery machine, help guaranteeing to adopt the appearance effect that reclaims the prepared plastic products of plastic grain.

2, the stirring blade of toggle and crushing chamber can be by same motor-driven, and overall structure is simply compact like this, and cost is low, convenient operation and control.

3, utilize toggle to drive the vibratory sieve bucket, then the forms of motion of sieve bucket has only pure straight line to move back and forth, this vibrating mechanism reliability height like this, and long service life just in time satisfies the requirement of the moving equipment of the long-time not failure of oscillation of this need.
