Common Problem 1: The latch is stuck and cannot be unlocked; the lid of the floating fish food making machine cannot be removed.
This is the most common problem (accounting for 45% of lid opening failures). The core causes are wear and tear on the latch due to long-term use, material residue clogging the latch gaps, or aging and malfunctioning latch springs, preventing the latch from unlocking properly. Troubleshooting Tips: First, turn off the power. Use a brush to clean any material residue and dust from the latch gaps to prevent it from obstructing movement. Apply a small amount of cooking oil or lubricant to the moving parts of the latch, wait 1-2 minutes for the lubricant to penetrate, then gently press the latch with your fingers and use a special pry bar to gently pry the edge of the latch. Do not use excessive force to avoid breaking the latch. If the latch spring is malfunctioning and cannot be unlocked, remove the latch and replace it with a spring of the same specifications before attempting to open the lid. After opening the lid, clean the latch promptly to prevent it from getting stuck again.
Common Problem 2: Bolts on floating fish food maker machines are stuck, stripped, and cannot be disassembled.
This type of problem often occurs with bolts on the barrel cover and die head cover. The main causes are prolonged exposure to high temperatures, leading to thread oxidation and rust, or material residue sticking to the threads. In some cases, excessive force during operation causes the bolt threads to strip. Solutions: For bolts that are stuck (but not stripped): Clean the surface and threads of the bolt with a brush to remove rust and material residue. Apply rust remover (or a small amount of cooking oil), wait 3-5 minutes for the rust remover to penetrate, then use a suitable wrench to gently wiggle the bolt clockwise (to loosen the threads), then slowly unscrew it counterclockwise. Do not force it to avoid breaking the bolt. For stripped bolts: If the stripping is slight, use a non-slip wrench to hold the bolt head and slowly unscrew it. If the stripping is severe and cannot be removed, gently grind the bolt head with an angle grinder to expose a new stress surface, then unscrew it with a wrench. Alternatively, replace the bolt with a new one, applying high-temperature rust-preventive oil after replacement to prevent further stripping.
Common Problem 3: The lid is stuck to the main body of the floating fish feed extruder machine and cannot be separated.
This type of problem often occurs with the barrel cover and die head cover. The cause is material leakage during machine operation, which causes the material to stick to the interface between the lid and the machine, or the seal has stuck to the interface due to prolonged disassembly, preventing the lid from separating. Solution: First, ensure the fish meal making machine has completely cooled down. Use a brush to clean any remaining material from the lid and interface. Use a special pry bar (padded with a soft cloth to avoid scratching the machine surface) to gently pry the edge of the lid, applying even force point by point, allowing the lid to slowly separate from the interface. Do not apply excessive force to a single point to avoid deforming the lid. If the seal is stuck, use a plastic scraper to gently scrape off the stuck seal residue, or apply a small amount of cooking oil to lubricate the interface before gently prying the lid again. After separation, promptly clean any remaining material and seal residue from the interface, and check the seal for damage. If damaged, replace it immediately.
