„PP woven bag making machine is one of the most important machines in the pp woven bag production line. The PP woven bag production line has four important parts, the first one is plastic tape drawing machine, make whole piece woven film from Polypropylene (pp) particles, then cut into pp silk and wind in group one by one. The second one is circular loom.
PP yarn extrusion line is mainly composed of extruder, machine head, first stretching roller, heating plate, second stretching roller, winder and electrical control part. The extruder is mainly composed of a screw, a barrel, a hopper, a reducer and a drive motor. The machine head consists of three parts: three-way, filter net, filter plate and lip. In order to adapt to the production of recycled materials containing more impurities, the machine head adopts a tee and a filter plate with a large filtration area, and a suitable device is installed, and the net change operation can be performed by one person alone.
PP yarn rewinding machine matches the tape drawing machine to wind the tape into tape spindle for the weaving of circular loom. It adopts magnetic-driving which makes the winding speed twice as quick as that of combination winding machine and keeps the winding tension steady and winding spindle flat to improve the quality of weaving flatness, by macthine high speed tape drawing machine, it can increase the output and reduce the cost greatly.
A circular loom is used to create a seamless tube of fabric for things like tights, sacks, tshirts, fabrics, fire hoses and so on. Circular looms can be small „”jigs”” used for hand knitting or large high speed machines for modern garments.
Coating and laminating machine can be equipped for coating and laminating functions. Additionally, for R&D needs, we provide lab lines to test materials and methods. Various coating and laminating methods are available. Coating and laminating machine features the functions include slot die coating, gravure coating, spray laminating, and ultrasonic bonding systems. Depending on individual needs, the coating and laminating systems can also include splice tables, edge guiding, auto cutoff and transfer, slitting, scrap winders, liner unwinds and rewinds, camera systems, perforators, printers, and roll discharge systems.
PP woven bag printing machine is specially designed for printing the words and trademarks on the woven sacks and laminated sacks, non woven bags, jute bags and papers, as well as carton box. It can finish multicolor printing at one time.
PP woven bag cutting and sewing machine automatically accomplishes the heat cutting and bottom hemming at fixed length for color-printed or plain woven cloth roll, which saves labor forces. It adopts touch screen for setting, PLC for controlling and servo motor for driving in order to control the length of sack precisely. The mouth of bag is easy to open and won’t be conglutinated after heat cutting. With automatic counting, the finished sacks can be delivered in batches. With pneumatic rolling-up, it’s convenient to operate.
Cement woven bag making machine has the advantages of reasonable structure, stable performance, convenient operation, etc. It can produce cement bags with good sealing performance and a beautiful appearance. The device has a conveyor belt that feeds a continuous sheet of paper into the machine. The machine cuts the paper to the correct size and then prints the design on the bag. The machine then forms the bag and seals it. Cement woven bag making machine is an important piece of equipment for the cement production lines. It can be used to make cement bags with high efficiency and high quality. It also has the advantages of large output, low energy consumption, and good performance.
Non woven bag production line follows strict compliance to meet high quality standards. There is a significant system which is being followed depending on what type of non-woven shopping bag is about to manufacture. The first process is the Slitting Machine or commonly called the slitter rewinder. The second process is the printing machine. This process is the application of the desired color and design on the non-woven fabric. Non-woven shopping bag usually comes in different colors and styles so in this stage you will be able to decide which type of common color is being printed out on the fabric. This is sometimes incorporated with dyeing. The common color is usually black, green and even orange. The third one is an automatic non-woven bag machine. The last part of the process is the ultrasonic handle sewing machine.
Spun bond and melt blown are the most common methods to produce polymer-laid nonwoven fabrics in the spunbond or meltblown nonwoven production line. This is a process of melting and spinning.
