[0033] The transmission conveyor line 4 of the present invention transmits the strip material cut by the strip cutting component 6 to the cutting component for pelletizing, adopts a composite processing method for pelletizing, and divides the pelletizing process into two steps. First, the dried mango is cut into strips, and then the mango is pelletized by the pelletizing component 7 to ensure that the particle size is uniform and meet the requirements of dried mangoes of different varieties and sizes. The material digging component 3 pushes the material on the feeding track 2 to effectively control the overlapping phenomenon of dried mangoes; the material blocking component 8 blocks and filters the strip material on the pelletizing component 7, and can block and filter the dried mango stuck on the pelletizing component 7, thereby preventing the vibration of the material caused by the pelletizing process and reducing the waste of mango particles.

At the feeding place, the size of the pellets is controlled by the speed of the driving motor 95 through the drive of the roller to meet the pelletizing requirements, and the stroke of the tool meets the requirements of dried mangoes of different varieties and sizes.

[0045] In one embodiment of the present invention, the unloading track 5 includes a unloading rack, which is arranged on the frame 1. The unloading rack is provided with an unloading inclined plate 51. The upward end of the unloading inclined plate 51 is provided with a blocking plate, and the blocking plate is arranged opposite to the transmission belt 43.

[0046] Specifically, a blocking plate is provided at the upturned end of the unloading inclined plate 51. The blocking plate is arranged opposite to the transmission belt 43.

[0049] Usage process

[0050] The dried mango material is poured onto the inclined plate 23, and the material-discharging motor 35 drives the material-discharging roller 33 to rotate so that the material-discharging protrusion 34 thereon performs material-discharging and separation on the stacked dried mango material. Since the material-discharging protrusion 34 is provided on the material-discharging roller 33, the part with the protruding particles gives the dried mango a force to slide forward, effectively solving the problem of overlapping of the dried mango feeding, and conveying the dried mango to the transmission belt 43. The transmission motor 44 drives the conveying roller 42 to rotate and drives the transmission belt 43 to convey the separated dried mango material to the strip cutting assembly 6.

The mango strips are cut into strips, and the transmission motor 44 drives the conveyor roller 42 to rotate and drive the transmission belt 43 to transmit the strip dried mango material to the pelletizing assembly 7. The driving motor 95 drives the runner 93 connected to the driving shaft 92 to rotate to drive the sliding rod 72 to move back and forth on the guide frame 74 to achieve up and down reciprocating motion to achieve pelletizing action to the mango strips, thereby driving the cutter 73 on the cutting frame 71 to pelletize the strip material on the transmission conveyor line 4 to produce pelletized products. The cutter 73 is arranged on the cutting channel, and two baffle plates 81 are provided on the baffle frame. The baffle plate 81 can block and filter the dried mango stuck on the cutter 73, which can prevent the vibration of the conveyor belt caused by the processing of the cutter 73 and reduce the waste of mango particles.
