[0019] As attached Figure 1 To the attached Figure 3 The embodiment of the present utility model provides a feed opening adjustment mechanism of a reversible packaging machine, comprising a frame 1, a feed opening adjustment assembly 2 symmetrically arranged on the inner side of the frame 1, a body lifting assembly 3 arranged on the lower side of the frame 1, a reversible conveyor belt 4 fixedly mounted on the upper inner surface of the frame 1, and a telescopic column 5 fixedly mounted on the lower outer surface of the frame 1;

[0020] The material mouth adjustment assembly 2 includes a worm 21, a handle 22 is fixedly installed on the outer surface of one end of the worm 21, a worm wheel 23 is meshed on the outer surface of the worm 21, a connecting column 24 is fixedly installed on the outer surface of the upper end of the worm wheel 23, a limiting plate 25 is fixedly installed on the outer surface of the connecting column 24, and a roller 26 is rotatably connected to the inner surface of the limiting plate 25.

[0021] The worm 21, the worm wheel 23 and the connecting column 24 are all rotatably connected to the inner wall of the frame 1, and the outer surface of one side of the limiting plate 25 can be attached to the inner surface of the frame 1;

[0022] By turning the handle 22, the worm 21 is driven to rotate. The rotation of the worm 21 drives the two worm wheels 23 meshing on its outer surface to rotate relative to each other. The rotation of the worm wheel 23 drives the connecting column 24 to rotate, thereby driving the limit plate 25 to rotate synchronously, thereby realizing the adjustment of the material opening size of the packaging machine, thereby avoiding material blockage or excessive flow affecting the packaging accuracy and efficiency.

[0023] Among them, the body lifting assembly 3 includes a base 31, a motor 32 is fixedly installed on the inner wall of one side of the base 31, and a positive and negative screw rod 33 is fixedly installed on the outer surface of the output end of the motor 32. The outer surface of the positive and negative screw rod 33 is threadedly connected to a U-shaped frame 1 34, and the inner surface of the U-shaped frame 1 34 is rotatably connected to a connecting plate 35. The outer wall of one end of the connecting plate 35 is rotatably connected to a U-shaped frame 2 36. The base 31 is fixedly sleeved on the lower outer wall of the telescopic column 5, the positive and negative screw rod 33 is rotatably connected to the inner wall of the base 31, the U-shaped frame 1 34 slides on the inner surface of the base 31, and the U-shaped frame 2 36 is fixedly installed on the lower outer surface of the frame 1;

[0024] By starting the motor 32 to drive the forward and reverse screw rods 33 to rotate, the rotation of the forward and reverse screw rods 33 drives the two U-shaped frames 1 34 connected by threads on their outer surfaces to slide relative to each other on the inner wall of the base 31.

[0028] First, the device is placed in a suitable working area, and then according to the packaging requirements of the material, the handle 22 is turned to drive the worm 21 to rotate. The rotation of the worm 21 drives the two worm wheels 23 engaged on its outer surface to rotate relative to each other. The rotation of the worm wheel 23 drives the connecting column 24 to rotate, thereby driving the limit plate 25 to rotate synchronously, thereby realizing the adjustment of the material opening size of the packaging machine, thereby avoiding material blockage or excessive flow affecting the packaging accuracy and efficiency, greatly improving the flexibility and practicality of the device. When the height of the device needs to be adjusted, the motor 32 is started to drive the forward and reverse screw rods 33 to rotate. The rotation of the forward and reverse screw rods 33 drives the two U-shaped frames 1 34 threadedly connected on their outer surfaces to slide relative to each other on the inner wall of the base 31. The sliding of the U-shaped frame 1 34 causes the connecting plate 35 to rotate on the inner surface of the base 31 and the U-shaped frame 2 36, thereby pushing the frame 1 to move up and down, and then driving the telescopic column 5 to extend and retract, realizing the up and down movement of the frame 1, facilitating the height adjustment of the device, and further improving the flexibility and practicality of the device.
