Step 1: Pre-operation preparation, including safety precautions and pre-treatment of the fish food making machine

The core premise of lubrication operation is safety and minimal interference. Therefore, it is necessary to take precautions and pre-treat the equipment in advance to avoid safety hazards and incomplete lubrication. First, safety precautions: Operators must wear non-slip gloves, safety glasses, and work clothes. Loose clothing and jewelry are strictly prohibited to prevent lubricating grease from coming into contact with skin or clothing, or clothing from getting caught in moving parts. Second, tool and grease preparation: Prepare suitable lubrication tools and grease. Basic tools include a grease gun, grease can, funnel, rag, and brush. The lubricating grease should be a high-temperature resistant, wear-resistant grease specifically for floating fish food extruders (lithium-based grease is recommended, with a high-temperature range of -20℃ to 180℃, suitable for floating fish food makers). (Due to the high-temperature operation requirements of the machine), ordinary grease is strictly prohibited (it melts easily and has poor lubrication effect). Ensure that tools are intact and the grease is not deteriorated. Thirdly, equipment pretreatment: First, turn off the main power supply of the extruder, unplug the power cord, hang a "Lubricating in Progress, Do Not Start" warning sign, and assign a dedicated person to monitor the process. Wait for the equipment to cool down completely (the body temperature can reach 120-160℃ during operation, and needs to be cooled to below 50℃). Clean the surface of the equipment and the area around moving parts to remove material residue and dust, preventing impurities from mixing into the lubricating grease and affecting the lubrication effect.

Second step: Precise positioning and identification of core lubrication points

The key to lubrication of the floating fish food making machine is the moving parts. Precise positioning of each core lubrication point is necessary to avoid omissions or incorrect lubrication, ensuring that every moving part receives effective lubrication. First, the core lubrication point 1: the connection between the screw and the barrel. This is the core of the equipment's operation, subject to long-term high-speed friction, requiring focused lubrication to ensure smooth screw operation and reduce barrel wear. Second, the core lubrication point 2: bearings (motor bearings, screw bearings, gearbox bearings). Bearings are high-speed rotating components; insufficient lubrication can lead to bearing wear and seizure, affecting power transmission. Third, the core lubrication point 3: the gearbox. The gears inside the gearbox mesh at high speeds, requiring regular lubrication to reduce gear wear and lower operating noise. Fourth, the core lubrication point 4: the guide rails and sliders (inlet and outlet adjustment components). This area operates at a lower frequency, but prolonged lack of lubrication can cause adjustment jams, affecting production operations. Fifth, the core lubrication point 5: other moving parts, such as couplings and drive shaft connections, requiring regular, small-volume lubrication to ensure smooth operation.

Step 3: Standardized Operation, Lubrication by Part

First, floating fish meal processing Lubrication of the screw and barrel connection: Clean residual material and dust from the connection with a brush. Apply special grease evenly to the screw connection, keeping the thickness to 1-2mm. Do not apply too much (to avoid mixing with raw materials and affecting feed quality). Secondly, bearing lubrication: Both motor bearings and screw bearings have grease filling ports. Use a grease gun to slowly inject grease into the filling ports until it overflows from the bearing gaps (indicating sufficient filling). After filling, wipe away any overflowing grease with a cloth. For gearbox bearings, open the gearbox cover and apply grease evenly to the bearing surface, while simultaneously checking... First, check the grease level in the gearbox and replenish it promptly if necessary. Second, lubricate the gearbox: open the gearbox filler port and slowly pour in the special gear grease using a funnel until it reaches the level line (there are clear level marks on the inner wall of the gearbox). After filling, close the filler port and wipe away any excess grease. Third, lubricate the guide rails and sliders: wipe the surfaces of the guide rails and sliders with a cloth, and evenly apply the grease to the surfaces of the guide rails and the grooves of the sliders. After applying the grease, push the sliders back and forth to ensure even lubrication. Fourth, lubricate other moving parts: use a brush to apply a small amount of grease to the joints of the couplings and drive shafts to ensure smooth operation of the joints.
