Description

Conveying device for automatic production line of metal packaging container

Technical Field

The utility model relates to a working device of metal packaging container manufacturing equipment, in particular to a conveying device for an automatic production line of metal packaging containers.

Background

The metal packaging container manufacturing equipment is often provided with a conveying mechanism, so that the metal containers on the production equipment line production stations can be automatically transferred from one processing station to the next processing station to perform multi-station flow processing. The conveying mechanism on the existing metal packaging container manufacturing equipment can adopt an all-cylinder conveying mechanism and the like, but has the defects of complex and large mechanism and low conveying speed.

The present applicant previously filed chinese patent No. 201120268767.4, which is a transfer mechanism for metal can making equipment, is structurally characterized by comprising a placing plate, a left side normal feeder, a right side normal feeder, a motor, a speed reducer, a cam mechanism and a horizontal pulling cylinder, wherein the placing plate is fixed on a frame, the left side normal feeder and the right side normal feeder are respectively arranged at the left side and the right side of the placing plate, the left side normal feeder and the right side normal feeder are respectively in running fit and sliding fit on the frame, the speed reducer is fixed on the frame, the motor is connected with an input shaft of the speed reducer, the cam mechanism is connected on the left side normal feeder and the right side normal feeder and the cam thereof is in outward pushing fit with the left side normal feeder and the right side normal feeder, a driving rotating arm of the cam mechanism is connected with an output shaft of the speed reducer, and the horizontal pulling cylinder is connected between the left side normal feeder and the right side normal feeder and is in inward pulling fit with the left side normal feeder and the right side normal feeder. The left side normal feeder and the right side normal feeder can be respectively composed of a sliding rotating rod which is rotatably matched and is in sliding fit with the rack, a can clamping rack which is fixed on the sliding rotating rod, and a clamping fork which is fixed on the can clamping rack and extends towards the inner side.

When the driving rotating arm is driven to rotate by the speed reducer, the connecting rod pulls the cam mechanism together with the left normal transmitter, the right normal transmitter and the transverse pulling cylinder to reciprocate on the sliding sleeve seat of the rack, and simultaneously the connecting rod drives the cam to do reciprocating swing motion; when the cam does reciprocating swinging motion, the working surface of the cam pushes the clamping tank bracket outwards through the roller, so that the left clamping fork and the right clamping fork are opened to release the metal tank; when the non-working surface of the cam releases the tank clamping frame through the roller, the left and right side normal feeders are pulled in the horizontal pulling cylinder, and the left and right clamping forks are closed in the horizontal pulling cylinder to clamp and hold the metal tank; when the left side normal conveyor and the right side normal conveyor reciprocate back and forth, the metal cans placed on the placing plate can be clamped and released, and can be continuously conveyed forwards and continuously conveyed from one processing position to another processing position. However, the disadvantages of this solution are: since the spread width of the left and right side normal feeders is limited by the outer diameter of the cam, when metal cans of different diameters are conveyed, the metal cans cannot be adapted by adjusting the conveying mechanism and can be adapted only by replacing the cam, which not only increases the operation cost, but also reduces the operation efficiency.
