Method of operation

 Bag centralization – Machine inlet :  The bags can be fed to the inlet of the machine by roller or belt conveyor. By either method the bags are presented to a set of grip faced powered rollers situated within the machine inlet. The powered rollers propel the bags forward between adjustable side guides to centralise the bags prior to the main Belt  conveyor of the “pneuCONVEYOR” Bag Slitting machine.

Automatic location :  A bag passing through the centralising guides is automatically collected by the twin adjustable paddle. The twin paddle guide the bag to move thoroughly on the belt conveyor where it gets cut by 2Nos. Knife cutter.

Bag slitting :   The Machine is provided with Multi cut  Blade, In multi cut, the bags are impaled onto a high speed cutting knife. To impale the bags against the knife the machine literally “drops” the bag from a height of about 2 to 3 feet onto the blade. The moment the bag is slit, the material spills out.  The rotating knife is adjustable for cutting depth. Bags are conveyed across the rotating knife and are slit open lengthwise. A set of adjustable rollers exert pressure on the bags, to ensure that they are fully cut by the knife cutter. 

Product discharge :  After multi cut of bag, the cut bag is tumbled in an inclined wire mesh drum in which the bag is repeatedly lifted and dropped as it moves forward to the exit. Material falls through the mesh to a collection hopper while the cut bag pieces find their way to a bag compactor & finally get discharge through screw conveyor.

Ancillary Equipment :  The unit can be supplied with a wide range of ancillary equipment. Platforms, supports and catwalks are designed to any client specifications.

Dust filter unit :  Mechanical- or Reverse Jet dust filter in several executions place don top or next to the machine. An integrated dust filter is placed on top of the machine directly above the cutting- and vibration area. The pneuCONVEYOR can be fitted with 3 pipe connections for ducting to an externally placed dust filter. Choice of type of filter is determined by the product handled.

Operator/control panel :  Fitted with motor contactors and motor protectors. Control facilities include door mounted LCD display for all alarm and event messages and PLC controller with Start/Stop sequence.

Belt conveyor in various executions :  Almost any desired type of belt conveyor can be fitted to the bag slitting unit for automatic bag in feed. Choice of belt conveyor type is subject to local situation, type of bag and desired working height. Belt width varies from 500 till 600mm with a maximum elevation angle of approx. 35°.

Rotating-brush cleaning-unit :  To prevent contamination of product when bags are used with dirt or dust on the outside, a rotating-brush cleaning-unit can be placed at the bag inlet of the “pneuCONVEYOR” machine.

Screw conveyor :  For mechanical conveying of product after discharge.

Rotating sieve or built-in vibrating screen : For removal of contaminants and lumps from product after discharge.

Crusher / lump breaker :  For breaking down lumps and agglomerates from the conveyed productroduct after discharge.

Rotary blowing seal :  A blowing seal can be fitted directly under the product hopper to accommodate pneumatic conveying of product after discharge.

Bag compactor :  A screw compactor can be fitted at the discharge chute of the machine. Bags are compacted and discharged into plastic bags secured to the outlet of the compactor.

pneuCONVEYOR – Multi cut is a versatile automatic slitter and earns its name owing to its ability to cut any type of bag be it paper or polythene. It is ideally suited to Indian conditions where the raw materials in bags are not properly sealed.

SALIENT FEATURES:

• Loss free, dust free bag handling.
• Increased efficiency and productivity
• Pneumatically operated opening system.
• Low cost easy maintenance.
• Low spares requirement.
• Available in a wide range of construction materials including SS316.
• Belt system ensures positive feeding of the sacks. The fact that spikes are not used on

  the belts ensure positive discharge into the waste bag compactor.
