When the primary feeding is finished, the 86 stepping motor 105 controls the feeding control baffle 102 to reduce an included angle between the feeding control baffle and the slope, so that the welding rod is prevented from being discharged continuously; the mechanism comprises a coarse screening control part and a fine screening control part, wherein an initial included angle between a feeding control baffle plate 102 of the left coarse screening part and a slope of a feeding trough 104 is larger so as to improve feeding efficiency, and an initial included angle of the right fine screening part is smaller so as to ensure accuracy; the feeding trough 104 is divided into two areas to prevent the newly added electrode from impacting the feeding control baffle 102, resulting in a sudden large discharge of the electrode, as shown in fig. 4.
As shown in fig. 5, since the weight control is performed by passing through three stations, namely, a coarse screening station, a fine screening station and a feeding station by station, the transfer of the welding rods between the three stations needs to be realized by the feeding conveyer 2, the servo motor 205 advances the feeding hopper 211 by one station every time of movement; in order to detect the weight of the welding wire in the hopper, the feeding hopper 211 is provided with a first weight sensor 212. The first weight sensor 212 is used to detect the weight of the welding rod in the feeding hopper 211.
As shown in fig. 6 and 7, the second weight sensor 309 is used for detecting the weight of the welding rod in the weighing hopper plate 305, and after the weight meets the requirement, the transition 86 stepping motor 307 controls the weighing hopper plate 305 to rotate, so that the bottoms of the two weighing hopper plates 305 are separated to form a middle gap, the hopper is opened, the welding rod falls from the middle gap to the lower side, and the state before and after the weighing hopper 305 is opened is shown in fig. 8.
As shown in fig. 9, in order to ensure the product quality, the weight of each package of welding rods is strictly controlled within the required range, the welding rods are separated one by adopting a one-by-one screening mechanism 4 and then added to the transitional weighing hopper 3 one by one, the welding rods are placed in the middle of the screening baffle 408, a 57 stepping motor 402 drives a double-sided tooth synchronous belt 407 to move, because each groove outside the double-sided tooth synchronous belt 407 can just accommodate one welding rod, after the welding rods are blocked by the screening baffle 408, only one welding rod is left at each groove of the double-sided tooth synchronous belt 407, the one-by-one separation of the welding rods is realized, and then the rotating angle of the 57 stepping motor 402 is controlled to make the welding rod on one groove drop to the transitional weighing hopper 3 at each rotating angle, so that.
Therefore, the automatic weighing and feeding device can realize automatic weighing and feeding of the welding rods, solves the problems of high labor intensity, poor packaging quality and the like caused by manual weighing in the conventional welding rod packaging process, and improves the feeding efficiency and precision of the welding rod packaging machine.
