[0016] Second, by arranging a tightening mechanism on the conveyor belt, a spring is arranged on the tightening mechanism, and the relative position between the two guide frames can be adjusted by rotating the connecting sleeve on the tightening mechanism, so that the conveyor belt is tensioned to avoid slipping. At the same time, the eccentric roller is driven to rotate by the second motor, so that the eccentric roller and the conveyor belt are in periodic contact, and cooperate with the spring on the tightening mechanism to keep the conveyor belt vibrating. Through the vibration of the conveyor belt, the raw material casting speed on the conveyor belt is accelerated, ensuring the flatness of the surface of the product after molding.
