The feeding unit is designed to streamline the paper feeding process into the machines. It starts with paper reel securely mounted on an air expanding shaft, which is then fed into the machine using a swing arm equipped with a hydraulic lifting system. This unit is enhanced with several key features: an alarm function that alerts when paper feeding is required, an automatic web guide system for improved paper surface smoothness, and a uniform tension control to ensure consistent paper feed. Additionally, changing paper rolls is simplified through an easy-to-use button control, making the process straightforward and efficient.

This unit efficiently die cuts a window on the paper and makes an easy-tear line, enhancing the functionality and user experience of the final product.

The glue spraying and pasting unit uniformly applies adhesive onto the paper. Following this, it pastes peel and seal paper onto the glued area, ensuring a strong and clean bond.

The handle making unit start the handle making process by simultaneously feeding two rolls of patch paper and one roll of paper rope. The paper rope is then adhered to the patch paper using a combination of water-based and hot melt glue. Following this, a compression device ensures the handles are firmly attached and aligned. The final step involves cutting the handles to the required length and transferring them to the handle patching unit, ready for the next stage of bag assembly.

The handle pasting unit in our paper bag making machinery is a key component for attaching handles. Once the handle strips are cut to size, they are precisely positioned onto the designated area of the paper bag. The unit applies a water-based adhesive to bond the handle to the bag securely. Following this, the handles are firmly pressed onto the bag surface to ensure a strong attachment. This process is completed before the bag is sent to the forming unit for pre-creasing, preparing it for the final production steps.

The bag forming unit plays a crucial role in shaping the final product. It begins by forming the glued paper, complete with handles, into tubes. These tubes are then precisely cut into individual pieces as per the set requirements. The next stage involves transferring these tubes to a drum mechanism, which opens them into a four-cornered shape, aided by a vacuum suction system. Following this, the bottom of the bag is glued, sealed, and formed into a square shape. The final step involves compressing and delivering the finished bags out of the machine.
