Description

Technical Field

[0001] The utility model relates to the technical field of automatic screw locking machine equipment, in particular to a screw feeding inclined barrel. Background Art

[0002] The automatic screw locking machine conveys the screws to the locking mechanism for locking through the feeding mechanism. The existing feeding mechanism generally uses a pushing device to push the screws to the transmission mechanism, or uses a hopper to make the screws fall to the transmission mechanism under the action of gravity for feeding. However, this type of feeding mechanism is difficult to ensure the continuity of screw feeding, and the amount of screws that can be loaded is relatively small. For example, the utility model patent with application number 201520057436.4 discloses a screw feeding device, which is provided with a bending plate on the inner wall of the feeding mechanism, the bending plate is close to the bottom of the feeding mechanism and the bending direction is consistent, and then the screws are fed through the bending plate through the rotation of the feeding mechanism. However, in this type of structure, in order to allow more screws to fall into the flat vibration mechanism through the bending plate, more bending plates need to be provided, but the increase in the number of bending plates not only takes up space and affects the loading amount of the screws, but also affects the stable flow of the screws when the feeding mechanism rotates, thereby affecting continuous feeding.

[0006] Furthermore, the drum includes a first drum body, a drum bottom and a drum cover, wherein the drum bottom is arranged at an end of the first drum body away from the discharge port, and the drum cover is arranged at an end of the first drum body close to the discharge port.

[0007] Furthermore, the drum also includes a second cylinder, which is coaxially sleeved on the outer periphery of the first cylinder.

[0008] Furthermore, the first cylinder is a hollow cylindrical structure.

[0009] Furthermore, the first ends of the plurality of spiral guide plates are evenly spaced in the circumferential direction of the plane where the bottom wall of the drum is located.

[0010] Furthermore, the plurality of spiral guide sheets have the same lead and helix angle.

[0012] Furthermore, the bending portion is arranged in an arc shape extending from one side connected to the inner wall of the drum to the other side along the radial direction of the drum.

[0013] The beneficial effect of the utility model is that the utility model discloses a screw feeding inclined barrel, which is provided with a spiral guide piece in the drum, so that the drum pushes more screws in the drum to the feeding blades through the spiral guide piece during continuous rotation, and then sprinkles them to the external screening channel from the feeding blades, thereby ensuring the continuity of screw feeding.
