The method of using a screening machine to conveniently hang bags and receive materials can be considered and implemented from the following aspects:

　　1、 Choose the appropriate feeding bag

　　1. Material selection: Based on the screening material characteristics and working environment of the screening machine, choose the appropriate material for the receiving bag, such as polyester, acrylic, fiberglass, etc., to ensure that the receiving bag has wear resistance, corrosion resistance, tensile strength and other properties.

　　2. Size matching: Ensure that the size of the feeding bag matches the discharge port of the screening machine, avoiding inconvenience in feeding or material spillage caused by being too large or too small.

　　2、 Install the material receiving device

　　1. Fixed bracket: Install a fixed bracket or hook below the discharge port of the screening machine for hanging the receiving bag. The bracket should be stable and reliable, able to withstand the weight of the material bag filled with materials.

　　2. Adjustment device: If possible, install adjustable brackets or hooks to adjust according to the actual size and weight of the receiving bag, ensuring that the receiving bag is securely hung and not easily detached.

　　3、 Optimize the bag hanging method

　　1. Hook tensioning method: For woven screens or screen plates with small thickness, the tail end of the screen or screen plate can be bent into a hook shape, or a thin steel plate and rubber pad can be used to wrap the edge of the screen and then bent into a hook shape, and then fixed to the bracket with hooks or bolts. This method can ensure the stability of the feeding bag and avoid damage to the screen or sieve plate.

　　2. Use specialized fixtures: There are feeding bag fixtures designed specifically for screening machines on the market, which can be easily fixed under the discharge port of the screening machine and firmly clamped onto the fixtures through adjusting devices. The use of this specialized fixture can greatly improve the convenience and stability of hanging bags.

　　4、 Precautions

　　1. Regular inspection: Regularly check whether the suspension device of the receiving bag is stable and reliable, to avoid the bag falling off or materials spilling due to looseness or damage.

　　2. Safe operation: During the process of hanging and retrieving bags, safety operating procedures should be followed to ensure the personal safety of operators.

　　3. Timely replacement: When the receiving bag is full of materials, a new receiving bag should be replaced in a timely manner to avoid overloading causing the receiving bag to break or the bracket to be damaged.

　　In summary, the methods for convenient bag hanging and feeding of screening machines mainly include selecting suitable feeding bags, installing feeding devices, optimizing bag hanging methods, and paying attention to safety and timely replacement of feeding bags. By implementing these measures, the efficiency and convenience of the screening machine can be greatly improved.
