The swing blanking device 100 guides the material into a receiving groove (not shown in the figure) to realize blanking of the material, and solves the problem that the material is piled up at a fixed position by conveying the material to a plurality of positions. The swing blanking device 100 comprises a blanking member 110, a driving mechanism 120 and a transmission mechanism 130, wherein the driving mechanism 120 drives the blanking member 110 to swing back and forth through the transmission mechanism 130, so that the blanking member 110 has a plurality of blanking stations.

It should be noted that, during the operation of the swing blanking device 100, the swinging of the blanking member 110 is continuous, and the blanking action of the blanking member 110 can be set to be continuous or intermittent by the blanking rhythm of the material on the blanking member 110, the distribution of the storage grooves, and the like. The number of the accommodating grooves can be set to be one, and the size of the accommodating grooves can cover the whole swing path of the blanking part 110, so that materials falling from the blanking part 110 which continuously swings can be collected, the falling rhythm of the materials does not need to be considered, and the blanking part 110 can realize continuous station blanking; the accommodating grooves can be arranged at intervals along the swinging path of the blanking part 110, the intervals between the accommodating grooves are arranged in a matched mode through the swinging speed and the blanking rhythm of the blanking part 110, and the blanking part 110 can achieve blanking at intervals.

The blanking member 110 serves to guide out the material falling thereon. In this embodiment, the blanking member 110 is obliquely arranged, and the material falling onto the blanking member slides down under the action of self gravity to slide to the opening at the end part of the blanking member 110, namely, the material falls into the accommodating groove at the rear part of the blanking opening to complete blanking. The blanking member 110 has a channel therethrough for guiding the material thereon. The blanking member 110 itself may be a groove body, or a pipe body, and the guide groove thereon may be a straight guide groove, or a guide groove in a specific form.

The blanking member 110 is rotatably connected to a machine table 200 to which the swing blanking device 100 is applied, the machine table 200 is provided with a guide member 210, the guide member 210 is communicated with the blanking member 110 for accurately guiding the material onto the blanking member 110, and the blanking member 110 is inclined downwards from the end communicated with the guide member 210.

The swing axis of the blanking part 110 can be perpendicular to the machine table 200, the projection of the swing path of the blanking port on the blanking part 110 on the machine table 200 is arc-shaped, the blanking part 110 swings left and right, and the guide angle is not changed; the swing axis of the blanking member 110 may also be parallel to the machine table 200, but perpendicular to the projection of the blanking member 110 on the machine table 200, so that the projection of the swing path of the blanking port on the blanking member 110 on the machine table 200 coincides with the projection of the blanking member 110 on the machine table 200, that is, a straight path, and the blanking member 110 swings up and down, and the guide angle changes.

In this embodiment, the swing axis of the blanking member 110 is perpendicular to the machine 200, the path of the blanking opening is an arc path, and the receiving slot is a box body with an opening facing the machine 200, and the opening covers the swing path of the blanking member 110. Compared with the up-and-down swinging of the blanking piece 110, the swinging range of the blanking piece 110 swinging left and right is larger, so that the falling materials can be more uniformly spread in the accommodating groove.

Illustratively, the transmission mechanism 130 includes a rocker arm 131 and a connecting rod 132, both ends of the connecting rod 132 are respectively rotatably connected with the rocker arm 131 and the blanking member 110, the driving mechanism 120 drives the rocker arm 131 to rotate, and the rocker arm 131 drives the blanking member 110 to swing back and forth through the connecting rod 132. The swing arm 131 has a fixed rotation shaft, and the blanking member 110 has a fixed rotation shaft. Thus, the rocker arm 131, the connecting rod 132 and the blanking member 110 form a crank rocker mechanism, the rocker arm 131 is driven to rotate by the driving mechanism 120, and the rocker arm 131 is linked with the blanking member 110 to swing back and forth through the connecting rod 132.

Meanwhile, the knuckle bearings 140 at both ends of the connecting rod 132 are twisted at 90 °, and the rotation axis of the rocker arm 131 is switched to be parallel to the machine table 200.

The driving mechanism 120 can directly drive the rocker arm 131 to rotate, and can also indirectly drive through other linkage components.

As shown in fig. 3, in another embodiment, the swing blanking device 100 further includes a linkage mechanism 150, and the driving mechanism 120 drives the rocker arm 131 to swing through the linkage mechanism 150, so as to drive the blanking member 110 to swing.
