Description

Technical Field

[0001] The invention relates to the technical field of packaging can manufacturing, in particular to a swing rod feeding machine. Background Art

[0002] When existing packaging cans or corresponding lids are produced, the cylindrical structure is conveyed step by step by a stepping can-holding or lid-holding clamping device. The clamping jaws need to have the functions of loosening the tube cylinder and clamping the cylinder, which makes the structure of the entire clamping jaw complex and occupies the width of the production line, making the production equipment occupy a large area. In addition, due to the complex structure of the clamping jaws, once a failure occurs, maintenance is time-consuming and labor-intensive. Summary of the Invention

[0003] In response to the above problems, the present invention provides a rocker feeding machine, which makes the conveying structure of cylindrical raw materials simple and reliable, and reduces the width space occupied by a single production line, ensuring that multiple production lines can be arranged within a unit area, thereby improving production efficiency.

The pairs of push claws 23 are used to locate the position of the product corresponding to each station.

[0033] The intermittent swing gear box 24 rotates one circle to drive the feeding push claw assembly forward and backward for one cycle;

[0034] A push rod seat 70 is provided directly below the position of the lower base body 12 corresponding to each processing station. The workbench 11 is provided with a through hole corresponding to each push rod seat 70. The upper surface of the push rod seat 70 is not higher than the upper surface of the workbench 11 when not in operation. The bottom of each push rod seat 70 supports an eccentric rocker 80.

[0035] The upper mounting frame 13 is provided with corresponding tooling corresponding to each work station.

[0036] The distance between the starting positions of the raw materials between the adjacent stations corresponding to the loading station 20 and several working stations is the same, ensuring accurate and reliable feeding;

[0039] In a specific embodiment, four groups of production lines are arranged in the width direction of the machine base 10, and each group of production lines corresponds to a can support servo motor 100, ensuring a small footprint;

[0042] Each production line only needs two servo motors to complete the processing operation, with good synchronization and low equipment cost.

[0043] Its working principle is as follows: the intermittent swing gearbox performs rotational motion, and the rocker arm drives the feeding connecting rod to swing synchronously. The product reaches the loading seat position through the inlet slide, and then the suction cylinder descends to make the product reach the unloading position corresponding to the unloading station. The product is sent to the position of each work station on the workbench through the pairs of push claws on each station. When it is delivered, the servo motor of the supporting tank is activated to lift the product through the push rod seat, so that the product is separated from the push claw and rises. The feeding frame is connected to the push claw and resets smoothly. After each work station is completed through the corresponding tooling on the upper mounting frame, the servo motor of the supporting tank is activated to support the product on the workbench again, and the feeding claw assembly drives the claw frame to cycle again, which makes the conveying structure of cylindrical raw materials simple and reliable, and makes the width space occupied by a single production line small, ensuring that multiple production lines can be arranged within a unit area, thereby improving production efficiency.
