Description

Technical Field

[0001] The utility model specifically relates to a low-noise automatic packaging machine, belonging to the technical field of packaging machines. Background Art

[0002] An automatic packaging machine is a highly automated piece of machinery, primarily used in the food, pharmaceutical, and chemical industries to automatically package materials. It integrates multiple functions, including metering, filling, bag making, sealing, cutting, conveying, and printing production batch numbers, significantly improving packaging efficiency and product quality. Automatic packaging machines are classified into two types: semi-automatic and fully automatic. Fully automatic packaging machines are fully automated, with everything from raw materials to finished products completed automatically by the machine, making them suitable for packaging scenarios requiring large-scale and high-efficiency packaging. However, existing packaging machines require clamping and fixing the top ends of plastic bags when feeding materials into them for packaging. During the clamping and fixing process, collisions in the clamping structure can easily increase noise. Furthermore, because plastic bags are relatively smooth, they can easily fall off during the filling process, resulting in low stability during the packaging process. Furthermore, the bag's opening size is difficult to adjust, making leakage more likely to occur during packaging. This creates certain drawbacks during use.

[0003] In view of this, the present utility model is proposed. Utility Model Content

[0009] Furthermore, in order to be able to drive the movable extrusion block to move through the driving slider, the self-resetting pushing assembly includes the limiting slide rod and the vertical mounting seat, the limiting slide rod is fixed in the connecting slot opened on the inner wall of the first positioning block and the second positioning block, the driving slider is slidably sleeved on the limiting slide rod, and the movable extrusion block is fixed on the driving slider.

[0010] Furthermore, in order to reset the driving slider by the reset spring, the driving slider is slidably engaged in the connecting slot, and the driving slider is elastically connected to the inner wall of one end of the connecting slot through the reset spring.

[0011] Furthermore, in order to drive the rotation drive rod to rotate by controlling the stepper motor to turn on, the vertical mounting seat is fixed on the top of the first positioning block and the second positioning block, the rotation drive rod is rotatably mounted on the inner wall of the vertical mounting seat, the stepper motor is fixedly mounted on the outer wall of one end of the vertical mounting seat, and one end of the rotation drive rod is fixedly connected to the output shaft of the stepper motor.
