Feed extrusion machinery manufacturer tells you: Installation and training of pet feed production line

Feed extrusion machinery manufacturers tell you: 1. In the control system of pet feed production equipment, a basic reference data for the arch-breaking feeding bin and feeder is the material flow rate. The addition amounts of water, steam, and other liquids in the system are all based on the material flow rate. Therefore, the stability of the material flow rate directly affects the stability of the entire extrusion production. To ensure stable material flow, the system adopts differential weight feeding, which places the entire feeding bin and feeder on a load cell, forming a closed-loop control among the load cell, variable frequency feeder, and computer to achieve feeding.

The basic requirement for differential weight feeding is the flexible connection between the upper and lower interfaces, namely the flexible connection between the arch-breaking feeding bin and the pneumatic gate at the upper part of the bin, and the flexible connection between the feeder outlet and the conditioner inlet. For these two flexible connections, canvas is typically used as the material for connection.

The feed extrusion machinery manufacturer tells you: The installation and training of weighing sensors for pet feed production lines is another important factor affecting feeding. There are usually two methods for sensor installation: hanging and supporting. Both methods can be selected based on site requirements. When using the hanging method, certain measures should be taken to ensure the stability of the bin. During the operation of the extruder, when material is fed into the feeding bin, the falling material causes the entire bin to shake. The amplitude and duration of the shaking are closely related to the length of the sensor tie rods. Although the control program retains the feeding data from before the material enters the bin during the feeding period, if the bin continues to shake after the material enters, it will directly affect the accuracy of the sensor weighing. Therefore, it is necessary to add a limiting device at the lower part of the bin, ensuring that this limiting device does not affect the weighing. The other installation method is the supporting method, which does not cause shaking, but the entire bin is prone to displacement. This requires fixing the sensor on the support frame during installation and installing limiting blocks on both sides of each lifting lug of the feeding bin to prevent the entire bin from shifting.

In the equipment of the Jinan feed extruder's anti-bridge feeding bin, attention should be paid to the location of the maintenance door. Ensure that the maintenance door can be opened, and a maintenance platform should be installed below the maintenance door.

2. Installation of the Jinan feed extruder's dual-shaft differential conditioner

Since the support frame of the dual-shaft differential conditioner is a welded assembly, deformation may occur during the transportation of the feed extruder. If the support frame is installed directly without adjustment after deformation, it will cause misalignment between the conditioner main shaft and the gearbox output shaft. During operation, the noise generated by the roller chain coupling will cause wear on the coupling gear and chain. Therefore, during installation, it is necessary to adjust the support frame to align the conditioner main shaft with the gearbox output shaft.

The relative position of the two main shafts is also required when installing the conditioner of the Jinan feed extruder. During installation, it can be carried out according to the marks on the shaft ends, or the relative position can be selected independently. Please refer to the manual for specific methods.
