Initially in this embodiment, the knocking wheel 32 does not touch the spreading plate 25, and the third spring is in a compressed state. When the material guide plate 20 rotates downward and tilts, the transmission gear 27 will be moved around the fixed gear 26 so that the transmission gear 27 will rotate. Pulling force, the third spring elastic force returns to drive the ring body 31, the second connecting rod 30, and the knocking wheel 32 to move towards the spreading board 25, so that the knocking wheel 32 hits the spreading board 25, and the shock falls and adheres to the spreading board 25 surface feed. When the material guide plate 20 turns back upwards, the transmission gear 27 will move back around the fixed gear 26 so that the transmission gear 27 will rotate in the opposite direction. Squeeze the third spring to compress it, which will drive the ring body 31, the second connecting rod 30, and the knocking wheel 32 to move away from the spreading plate 25, so that the knocking wheel 32 will be separated from the spreading plate 25 after knocking .

Along with the reciprocating tilting rotation of the material guide plate 20, this process is constantly reciprocating, realizing the intermittent knocking of the knocking wheel 32 on the spreading plate 25, so as to effectively shake off the adhered and bonded feed on the spreading plate 25 surface. During this process, the spreader plate 25 passes through the reel and the coil spring, which can buffer the rigid contact from the knocking wheel 32 that the spreader plate 25 is subjected to, so as to avoid damage.
