Description

Technical Field

[0001] The utility model relates to the technical field of packaging transportation, and specifically discloses a turret machine. Background Art

[0002] A packaging production line is a general term for a system. Generally, a packaging production line is composed of several different packaging machines and conveyor belts. Products in production or completed products are transported to the packaging production line for packaging processing, and after completion, they are sent out to become complete products that are convenient for transportation. When the product is packed in a packaging bag, there is a situation where the packaging bag needs to be transported in a turned direction during transportation.

[0003] Chinese Patent CN204916386U discloses an adjustable subcontracting machine, including a frame. One side above the frame is vertically fixed with a motor mounting seat. A stepping motor with an output shaft perpendicular to the top surface of the frame is fixed on the side of the motor mounting seat. A driving wheel is fixedly fitted on the output shaft of the stepping motor. A rotating mechanism is installed at the center of the top surface of the frame. The rotating mechanism includes a fixed sleeve fixed on the top surface of the frame. A rotating shaft extending downward through the top surface of the frame is rotatably inserted into the fixed sleeve. A driven wheel is fixedly fitted on the rotating shaft. A cover is fixed at the bottom of the rotating shaft. A clamping mechanism is installed in the cover. The clamping mechanism includes a clamp that can move along the long side direction of the frame. The upper end of the clamp is also symmetrically fixed with a rotating shaft. A horizontally arranged air cylinder is fixed on the rotating shaft. An air cylinder mounting seat is vertically fixed between the bottom of the air cylinder and the cover. After automatically clamping the material bag by the clamp, it automatically releases the material bag after turning and returns to the original position. The structure is simple and effective, avoiding the phenomena of tipping, deviation, and dropping during the turning process, and improving the production efficiency.

[0004] For the adjustable subcontracting machine disclosed in the above document, its clamp is directly pushed by an air cylinder, and the clamp is subjected to a large impact force at the moment of starting and stopping, which is easy to damage the air cylinder and the clamp. Therefore, a turret machine is needed to solve this problem. Summary of the Utility Model
