Description

Technical Field

[0001] This utility model relates to a flipping device for a packaging machine. Background Technology

[0002] Existing patent CN212667817U discloses a flipping bag clamping mechanism, including a sealing bag clamp, a flipping plate, a crank assembly, a support base, and two flipping cylinders for driving the flipping plate to flip. The flipping cylinders are divided into a front flipping cylinder and a rear flipping cylinder according to their front and rear positions. The rear flipping cylinder is fixed to the surface of the lower support base, and its piston rod extends forward and upward and is hinged to the crank assembly. The lower end of the front flipping cylinder is hinged to the support base, and its upper end is rotatably connected to the lower end of the flipping plate through its piston rod. The upper and lower ends of the crank assembly are respectively hinged to the flipping plate and the support base. It has the following shortcomings:

[0003] The crank assembly is controlled by the extension and retraction of the rear tilting cylinder. Since the rear tilting cylinder is easily affected by the pressure fluctuations of the pneumatic system, the extension and retraction speed is uneven, which makes the back-and-forth swinging motion of the crank assembly less smooth and affects the working efficiency of the packaging machine. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a turning device for a packaging machine.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a flipping device for a packaging machine, including a frame, a flipping plate is provided on the top of the frame, a rear flipping cylinder is connected between the flipping plate and the front side of the frame, and a flipping crank is connected between the rear side of the frame, and a crank-connecting rod mechanism driven by a motor is connected between the flipping crank and the frame to facilitate the forward and backward rotation of the flipping crank.

[0006] Preferably, the bottom end of the cylinder body of the rear tilting cylinder is hinged to the frame, and the top end of the piston rod of the rear tilting cylinder is hinged to the tilting plate.

[0007] Preferably, the initial posture of the flip crank when the flip plate is in a horizontal state is tilted, and it extends tilted forward from top to bottom.

[0008] Preferably, the bottom end of the flip crank is hinged to the frame, and the top end of the flip crank is hinged to the flip plate.

[0009] Preferably, the motor is fixedly connected to the frame.

[0010] Preferably, the crank-connecting rod mechanism includes a crank and a connecting rod.

[0011] Preferably, one end of the crank is fixedly connected to the output shaft of the motor, and the other end of the crank is hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to the reversing crank.

[0012] Preferably, a buffer assembly is provided between the front side of the flip crank and the frame, and between the rear side of the flip crank and the frame.

[0013] Preferably, each of the buffer components includes a riser fixedly connected to the frame, and each riser has a damper on the contact side near the rotating crank.

[0014] Preferably, the heightening seat has an inclined surface on the contact side near the flip crank.

[0015] Compared with the prior art, the present invention has the following advantages: the flipping device of the packaging machine uses a crank-connecting rod mechanism driven by a motor to drive the flipping crank to swing back and forth. The crank-connecting rod mechanism directly transmits power through its own mechanical structure, without the interference of medium compressibility, resulting in high speed stability, smooth motion trajectory, smooth and fast action, and improved work efficiency.
