Block Bottom Valve Bags Conversion Line

Block Bottom Valve Bags Conversion Line
Block bottom valve bags conversion line ,  New generation block bottom valve sack conversion line adopts hot air welding technology to produce laminated pp woven sacks.Block bottom valve sack is the most well known sack style in the world. It shares many advantages compared to other style sacks such as high strength, low cost, improving filing speed, suitable for automatic insert filing line, great environment protection, stably palletize, high efficient transportation, easy remark, etc. This line is widely used in cement, fertilizer, grain, feed, chemical material industry for packing powder and granule.2. Each line consists of:1 set UNWINDING STATION consisting of: automatic control for guiding the fabric length with transversely movable unwinding stand, tension controller (correction distance < 100 mm) roll monitoring system: alarm is given before the fabric roll is empty 2 winding shafts with pneumatic expansion chucks for a core diameter of 108mm (76 mm) 1 set PERFORATION SYSTEM for providing a pin perforation in the tubular fabric to achieve better air permeability of the AD*STAR. sack. Perforation is effected over the complete surface of the sack. 1 set CROSS-CUTTING UNIT for cutting the fabric to the preset length and consisting of: intermittent traction system with servomotor print mark reading device for printed tubular fabric pneumatically operated knife including brake valves in the end positions 1 set INTERMITTENT FEED SECTION WITH PIN TRANSPORT is the zone where the fabric length is cut. Consequently, the fabric is constantly decelerated and accelerated. The variations in speed are compensated by the compensator. The intermittent feed section consists of: intermittent pin transport unit Servo-drive with self-referencing function, thus ensuring a precise sack transfer manually adjustable (depending on the sack dimension) bottom opening station transfer station to the continuous transport section 1 set CONTINUOUS FEED SECTION is the zone where the sack is transported at a constant speed and without pins to the different folding devices and welding stations. The continuous feed section consists of: bottom closing by means of adjusting spindles belt system for the transport of the sacks via an acceleration belt from the main machine to the stacking unit 1 set MANUALLY ADJUSTABLE BOTTOM CENTER DISTANCE for sack length adjustment 1 set VALVE UNIT The valve patch, which has been cut from flat fabric, is applied onto the sack and welded by means of hot air. The valve unit consists of: unwinding station with band brake, monitoring system for fabric end andautomatic control for guiding the fabric length pneumatic expansion chuck traction unit with separate servo-drive for the infinitely variable adjustment of the patch length cutting unit for the valve patches, adjustment of the knifes with a special designed gauge is from outside possible. hot air welding device 1 set BOTTOM PATCH DEVICES The bottom patches, which have been cut from flat fabric, are applied onto the closed sack bottoms and welded by means of hot air. The bottom patch devices consist of: unwinding station with band brake, monitoring system for fabric end and automatic control for guiding the fabric length pneumatic expansion chuck traction unit with separate servo-drive for the infinitely variable adjustment of the patch length during the operation print mark reading device for printed bottom patches cutting unit for the bottom patches, adjustment of the knifes with a specially designed gauge is from outside possible. hot air welding device 1 set STACKING UNIT constructed as a conveyor belt with package separation for an individually adjustable sack number per package 1 set MAIN DRIVE consisting of: position-controlled servomotors with transport system without pins Duplex chain drive control elements drive connections to the other drive units by means of a software coupling 1 set ELECTRICAL INSTALLATION central power distribution for drive, heating and control systems control cabinet, completely installed and checked when connected to the line optimized energy distribution and protection of the line components modular machine structure for add-on and retrofit purposes highly advanced safety and monitoring equipment with checking system separate bus system for the drive system and the control level, including a clearly structured diagnosis system and an integrated software temperature control control cabinet cooling by circulating air, for unlimited ambient temperatures Block bottom valve sacks conversion line ,pp woven block bottom valve sack conversion line,pp woven block bottom valve bag conversion line,pp woven sack conversion line,pp woven bag conversion line,valve bag conversion line,pp valve bag conversion line,pp bag conversion line ,bag conversion line,block bottom valve bag conversion line, pp cement valve bag conversion line, cement valve bag making machine, square bottom valve bags conversion line,square bottom valve bags production line , block bottom valve sacks , square bottom valve bags, square bottom valve bags making machine, pp valve bags making machine, pp cement bags machine, square bottom valve cement bags production line,square bottom valve cement bags conversion line,square bottom valve cement bag making machine
