Introduction to Ton Package Feeding Station

1、 Mechanical structure inspection

1. Lifting and support system

• Hook/sling status：

• Visually inspect the hook for cracks and deformation (if the opening exceeds 15% of the original size, it needs to be scrapped);

• Whether the sling is worn or broken (fiber breakage exceeding 10% or local damage needs to be replaced);

• Whether the lifting connection of the crane/forklift is firm, and whether the lifting action during trial operation is smooth and without any jamming.

• Feeding station bracket and platform：

• Check whether the welding points and bolt connections of the bracket are loose (use a wrench to tap and listen for sound to determine);

• Whether the platform guardrail is intact and whether the anti slip pad is damaged (if there are holes or protrusions, they need to be repaired).

2. Unloading and arch breaking device

• Unloading port component：

• Manually rotate the discharge port valve/gate to check whether it opens and closes flexibly, and whether the sealing strip is aged (if it hardens or falls off, it needs to be replaced);

• Observe whether the discharge port is aligned with the ton bag interface, and whether the clamp or sealing ring is intact (to prevent material leakage).

• Vibration/arch breaking equipment：

• Are the fixing bolts of the vibration motor and pneumatic hammer tightened (check one by one with a wrench);

• Check if there is any air leakage in the pneumatic system's air pipe connection (soap water can be applied to detect bubbles), and if the pressure gauge value is within the specified range (usually 0.4-0.6MPa).

3. Dust removal and pipeline system

• Filter bag and dust collector：

• Open the dust removal box and check if the filter bag is clogged (if the color turns black or the pressure difference gauge value exceeds the set value, it needs to be cleaned);

• Whether the seam of the filter bag is damaged (small holes can be repaired with patches, and large areas of damage need to be replaced).

• Pipelines and valves：

• Check for cracks and air leaks in the dust removal pipeline (especially at the elbow and flange connections);

• Whether the butterfly valve and ball valve are flexible in opening and closing, and whether the sealing ring is aged (no jamming sensation during rotation is normal).

2、 Electrical system inspection

1. Power supply and grounding

• Power connection：

• Check if the indicator lights in the distribution box are normal and if the voltage is stable (three-phase power needs to be tested for phase to phase voltage of 380V ± 10%);

• Check for any damage or aging on the outer sheath of the cable, and whether the joints are loose (use a multimeter to check the continuity of the circuit).

• grounding protection：

• Use a grounding resistance tester to measure the grounding resistance of the equipment (should be ≤ 4 Ω), and check if the grounding wire is firmly connected to the grounding post.

2. Control components and sensors

• control panel：

• Whether the buttons and knobs are sensitive (with normal contact feedback after pressing), and whether the emergency stop switch is effective (the equipment should be immediately powered off after pressing);

• Whether the display screen is clear and whether the parameter settings (such as vibration time and dust removal fan power) meet the current material requirements.

• Sensor function：

• Level gauge (if any): Simulate feeding test to determine if high and low level alarms are triggered;

• Deviation switch (for belt conveyors): Manually toggle the switch to check if it can automatically stop the machine.

3、 Security protection inspection

1. Integrity of protective devices

• Safety fence and warning signs：

• Whether the safety fence around the equipment is closed, and whether the entrance and exit doors are equipped with interlocking devices (the equipment cannot be started when the door is opened);

• Are warning signs such as' No Overloading ',' Attention to Dust ', and' Beware of Mechanical Injury 'posted in prominent locations.

• Dust and explosion prevention measures：

• In an explosion-proof environment, check whether the equipment is explosion-proof (motors, switches, etc. need to have Ex explosion-proof markings);

• Whether the anti-static ground is grounded, and whether the operators are wearing anti-static work clothes and shoes.

2. Emergency equipment and channels

• firefighting facilities：

• Is the operating area equipped with dry powder fire extinguishers (for combustible dust) or sand boxes, and is the pressure of the fire extinguishers normal (pointer in the green area);

• Is the fire escape clear and free of debris.

• first aid supplies：

• If handling toxic materials, it is necessary to equip eye wash stations, first aid kits (including chemical resistant gloves, disinfectants, drugs, etc.), and ensure that they are within their validity period.

4、 Material and tooling compatibility inspection

1. Matching ton bags with feeding ports

• Confirm that the size of the ton bag (such as the spacing between the lifting straps and the position of the discharge port) matches the slot of the feeding station bracket to avoid tilting during lifting due to non-compliance with specifications.

• Check the appearance of the ton bag for any damage, moisture, or cracked seams, and ensure that the material labels are consistent with production requirements (to prevent mixing).

2. Process parameter preset

• Based on material characteristics such as fluidity, humidity, and particle size, set vibration frequency, discharge port opening, and other parameters in advance:

• Materials with good fluidity: The initial opening can be set to 50%, and the vibration interval time can be extended;

• Materials prone to clumping: Start the arch breaking device in advance and pre vibrate for 10-20 seconds.

5、 Trial operation and recording

1. No load trial operation

• Start the dust removal fan and observe if it runs smoothly and if there is any abnormal noise (which should be a uniform buzzing sound during normal operation);

• Test vibration device: run for no more than 10 seconds at a time, feel whether the vibration intensity is uniform and there is no severe shaking.

2. Problem Handling and Recording

• If problems such as loose bolts or air leakage in pipelines are found, they need to be repaired immediately and rechecked;

• Fill out the "Equipment Inspection Record Form", record the inspection time, identified problems, and handling results, and have the operator and safety officer sign and confirm.
