In order to meet the packaging requirements of cargo storage, transportation and mechanized loading and unloading operations, we have designed and manufactured a series of products such as pallet wrapping machine, top-pressing type resistance winding machine and pre-drawing type automatic film winding machine. The cost of assembly of products such as beverage, irrigation system, paper making, dye, plastic chemical, glass ceramic and electromechanical casting increases the production efficiency, prevents the goods from being damaged during handling, and plays a role of dustproof, moisture proof and cleaning. PLC programmable controller control. Can set the number of windings, you can choose to strengthen the local, automatic reset and so on. With overload, over current protection, safe and reliable. The design is concise and easy to maintain. Closed structure, durable.
