Pocket spring mattress making machine is fully automatic nc operation. As a result of the use of back sealing ultrasonic edge sealing.In the production of thicker steel spring can also be used in a thinner non-woven fabric. With empty cutting part length setting and cloth consumption automatic stop and other functions. Thus improves the intelligence of the machine, so that the production of the product cost is lower, less waste, the structure is more solid, is independent bag bed mesh and sofa seat package ideal equipment.
Features:
1.It can produce drum, straight drum spring.
2.Connection function of non-woven fabric, saving fabric and loading time.
3.Reliable heat treatment system, quick and convenient adjustment.
4.Each station is equipped with detection and alarm device, which makes the fault clear and convenient to deal with.
5.The spring relief system has been improved, compared with the same industry machine,more safe and reliable operation.
6.The wire delivery system has been improved, compared with the same industry machine, more safe and reliable, not easy to mess.
7.Full servo precision control, greatly reduce the amount of gas used and reduce the maintenance rate of pneumatic components, more stable operation.
8.More user-friendly procedures,more safe and stable operation.
