Application of LB series and K1 servo driver of Huada servo motor in slitting machine
1.Introduction
The sewing machine is an important splitting, cutting and sewing equipment in the woven bag industry. It does not need any mold. It directly cuts and sews the products according to the cutting and sewing production process of the woven bag through the control of the system software. It only needs to set the corresponding parameters on the operation platform, and it is highly automated, simple to operate, and the products produced are standard and tidy. It can completely replace the previous heavy physical labor, reduce the error rate, reduce the human consumption, and integrate the performance advantages of the woven bag equipment of the sewing machine, which inject new vitality into the production of woven bags and improve the production efficiency.
Characteristics are as follows
1、 It can automatically finish the fixed length thermal cutting and bottom sewing of the woven tube cloth, saving labor.
2、 Touch screen setting, PLC control, servo motor drive, precise control of bag length.
3、 After thermal cutting, the bag does not stick and is easy to open.
4、 Automatic counting, bag can be stacked.
5、 Pneumatic feeding, convenient operation and labor saving.
2.Equipment function and commissioning requirements
This product is suitable for the processing and packaging of various cement bags, flour bags, feed bags, sugar bags, fertilizer bags, etc. All processes of feeding, folding, sewing, breaking, receiving, cutting and counting of woven bags can be completed by one person, which are closely matched and do not interfere with each other.
The equipment process is divided into roll up – cutting – holding – sewing bottom – bag collection.
The correct operation method of the whole machine of weaving bag hot seam.
1、The woven bag hot seam machine hangs the cloth on the shaft, on the pressing wheel which overwhelms the hot seam, the pneumatic automatic feeding.
2、Automatic correction.
3、Color mark tracking, servo control bag length.
4、Hot cutting, automatic rubbing, cold knife device.
5、PLC centralized control, color man-machine interface, set data, display and record.
6、Frequency control, automatic counting.
7、 Automatic bag folding and conveying.
Device parameters
Rated voltage: two-phase / three-phase
Sewing needle pitch: 5-14mm
Bag cutting speed: 20 ~ 40pcs / min
Bag cutting length: 500 ~ 1300mm
Bag cutting width: 800mm
Debugging requires precise positioning of servo driver to ensure uniform bag length and neat stitching track.
