Use process:

No-load machine test: before starting the machine every day, inch the motor and listen carefully to whether there is friction sound. In case of friction, immediately shut down the machine for inspection and adjustment. Start the machine for no-load test run after troubleshooting. Check whether the pressure of the pressure regulator is proper before startup, and normally idle for half a minute. Note that the no-load operation time should not be too long, generally not exceed 30 seconds. When the machine is shut down for a long time, it shall be started for idling for 1 minute every half month to prevent the parts from rust.

Uniform feeding: feed raw materials into the hopper immediately after the machine is started. The feeding shall be uniform and continuous. Idle operation is strictly prohibited. The feeding method adopts feeding belt and clamping flat belt, playing a stable feeding function, which is beneficial to the positive feeding of fish conveying clamp and not easy to slide. The middle part of the feed belt is designed with a V-shaped guide groove to ensure the overall effect during fish driving. If the fish is too large, cut it into small pieces or pick it up with a wooden cabinet. Raw materials must be mixed with stones, ironware and other hard sundries to avoid damaging the machine.

Automatic discharging: the fish body is cut into three pieces, i.e. one piece of middle bone of the fish and two pieces of fish willow, so as to completely remove the fish meat on the middle bone. Processed products are horizontally discharged from the outlet of the machine along the conveyor belt to complete automatic flow process. Fishbone ejects from the bottom of the machine. Stop the equipment after the framework in the hopper is emptied. The fish after discharging can be sent to the subsequent processing equipment such as the peeling machine via the rear conveyor.

Versatility and durability

Feeding mechanism: the feeding box adopts reverse thread and positive thread design, which can easily adjust the belt width. The feeding mode adopts one feeding belt and two clamping flat belts for stable feeding of fish, which is beneficial to the positive feeding of fish conveying clamp and not easy to slide. The middle part of the feed belt is designed with a V-shaped guide groove to ensure the overall effect during fish driving. A synchronous part is arranged on the rack to drive two clamping wheels to move close to or away from the rack synchronously, so as to keep the fish in the center all the time and avoid accidental injury caused by offset.

Cutting mechanism: the auxiliary knife is set in front of the main knife, and the auxiliary knife adjusts the position through the upper and lower adjusting rods and the left and right adjusting rods to assist the main knife in cutting. The auxiliary knife and the main knife share the same power and are driven by the chain to improve the yield of fish. The blades are designed as multiple pairs of removable structures, and the cutting blades with different functions are successively arranged along the conveying direction to realize accurate slitting. The cutting strength can be adjusted according to the size of the fish to ensure the integrity of the meat.

Modular design: the fish bone remover adopts modular design, and each functional component is relatively independent. Core components such as blades, conveying components, etc. can be quickly removed, replaced and cleaned. No special tools are required for the disassembly and assembly of the complete machine, which is easy to maintain and minimize the downtime. The modular structure facilitates flexible integration with existing production lines and can also be customized for different fish species. The equipment is compact and easy to move and deploy among different stations.

Simplified operation process

Check the blades and fasteners before startup, and test the machine with no load for half a minute after inching and hearing. Then the feeding is uniform and continuous, the equipment automatically completes the cutting, and the fishy willow and middle bone are discharged respectively. When the work is completed and the framework is emptied, shut down the machine, disassemble the blades and removable parts, wash and clean them with water, and dry them for assembly. Easy operation in the whole process, easy for novice to master.

Frequently Asked Questions

How to solve the problem that the fish has bone or is not completely separated after being cut by the fish bone slitting machine?

Common causes are worn or improperly installed blades that need to be replaced or re-tightened. The clearance between the blade and the conveyor belt is too large, and turn the hand wheel to reduce the clearance. If the positioning device is not adjusted when the fish spec. changes, it shall be re-calibrated so that the fish is centered against the blade.

How to solve the problem of incomplete fish bone separation during fish slitting machine processing?

The common reason is that the blade position deviates or the clearance is too large. Readjust the blade depth to make it close to the spine for cutting. The feeding speed is fast and slow to maintain uniform feeding. If the size of raw fish is not adjusted timely due to large difference, the clamping wheel and blade positioning shall be synchronously adjusted according to the thickness of fish body.   

Mode of maintenance:

Daily maintenance: after the work of each shift, the equipment shall be emptied and stopped. Dismantle the contact parts such as conveyer belt, blade and meat barrel, wash the residue with clean water, and do not directly wash the motor and electrical parts with high pressure water gun. Check whether the blade edge is damaged and whether the fasteners are loose. Wipe the machine body and apply food grade lubricating oil on the movable joint. Assemble and check whether it is normal during no-load operation.

Regular maintenance: weekly check the tension of transmission chain and belt, and add lubricating grease on the bearing. Check the oil level and quality of the reducer monthly, and add or replace new oil in case of insufficiency. Check the abrasion of the conveyor belt and the elasticity of the rubber belt, and replace it in case of serious abrasion. Check the electrical circuit, fasten the connecting terminal and test the effectiveness of the emergency stop safety device quarterly. It shall be operated again after being idle for more than one month to prevent corrosion of components.
