Perforator for hollow bodies Description

The perforator for hollow bodies is mainly used in sorting plants for recyclable materials according to Germany's dual system.

In recent years, the proportion of PET beverage bottles has grown steadily. These PET beverage bottles are so strong that they do not burst when closed in the baling presses currently in use and can be compressed without trapping air.

The perforator has the task of creating openings in closed hollow bodies (plastic containers) through which the air trapped in the hollow body can escape when it is pressed into bales.

As the air in the hollow bodies escapes, greater compaction and thus a higher bale weight is achieved during pressing, resulting in savings in the storage space required for the bales and in the transport costs of the bales from the sorter to the recycling plant.

The perforator can be fed in different ways:

1. manual

2. by conveyor belt

3. by front loader

4. in the filling shaft of a baler

The size and design of the perforator depends on the type of feed and the hollow body throughput per hour.

The perforator for hollow bodies essentially consists of the following components (see drawing sheet 1):

(1) Housing

(2) Toothed drum

(3) Referrer

(4) Constriction slope

(5) Scraper

(6) Drive

(7) Material flow distributor

The hollow bodies to be perforated are guided by the guide (3) between the toothed drum (2) and the side wall of the housing (1), whereby the flow divider (6) promotes an inclined entry for better feeding of the hollow bodies.

The teeth of the toothed drum (2) pull the hollow bodies downwards over the constriction slope (4).

The gap narrows in this way and allows the teeth of the toothed drum (2) to penetrate into the hollow bodies.

After passing the constriction slope (4) the hollow bodies fall downwards.

Any hollow bodies adhering to the drum are removed from the toothed drum (2) by the scraper (5).

The toothed drum is driven directly by a commercially available gear motor.

The removal of the perforated hollow bodies is carried out in a user-specific manner.

Claims (6)

1. Perforator for hollow bodies, characterized in that only one toothed drum ( 2 ) presses the material to be perforated (hollow body) against a constriction slope ( 4 ). 2. Perforator for hollow bodies, characterized in that a flow divider ( 6 ) feeds long hollow bodies predominantly obliquely (for better capture by the toothed drum ( 2 )) to the press gap. 3. Toothed drum ( 2 ), characterized in that the toothed rings ( 8 ) are fastened to the drum as a unit or as removable segments. 4. Toothed drum ( 2 ) characterized in that its distance from the constriction slope ( 4 ) is continuously adjustable. 5. Toothed rims ( 8 ) characterized in that the tooth shape is designed in such a way that adhesion of the hollow bodies is made difficult. 6. Toothed rims ( 8 ) characterized in that the entrainment and perforation of the hollow bodies is promoted by teeth ( 9 ) of equal or different heights (depending on the type of hollow body).
