Technical Field

[0001] This utility model relates to the field of medical packaging equipment technology, and in particular to a sterile dressing packaging cutting device. Background Technology

[0002] With the advancement of medical technology and the improvement of people's health awareness, the market demand for sterile dressings, as a commonly used medical consumable, has shown a rapid growth trend. From daily wound care to applications in various surgeries, the scope of use of sterile dressings is constantly expanding. During the production and packaging of sterile dressings, it is necessary to package and cut them into individual pieces, so a sterile dressing packaging and cutting equipment is used.

It often requires frequent manual loading and unloading and adjustment of equipment parameters. The packaging material is placed on the cutting table by hand, the machine is started to cut, and then the cut packaging is removed manually. This is time-consuming and labor-intensive, resulting in low work efficiency. Utility Model Content

[0016] The aseptic dressing packaging and cutting device provided by this utility model has the following advantages:

[0017] With a feeding structure, sterile dressings are stacked inside the feeding box. A micro motor drives the feeding roller to rotate, causing the feeding roller to remove the sterile dressing at the top through the discharge port. The sterile dressing slides down to the top of the worktable under the guidance of the slide plate. The packaged and cut sterile dressings are then transported to the inside of the collection box by the unloading roller. This device realizes the function of automatic loading and unloading, thereby improving the working efficiency of the sterile dressing packaging and cutting equipment during use.

[0018] With the first slitting structure, the electric push rod drives the lifting plate to move downward, so that the electric heating rod presses down to heat seal the packaging film. As the electric push rod presses down, the return spring contracts, so that the first slitting blade cuts the heat seal, thus realizing the function of the device to facilitate heat sealing and slitting, thereby improving the convenience of using the aseptic dressing packaging slitting equipment.

[0019] By incorporating a second slitting structure, the slitting pressure roller slides on the outside of the drive shaft, causing the second slitting blade to be collinear with the separator plate. Rotating the threaded handle causes one end of the threaded handle to abut against one side of the shaft key, thereby fixing the slitting pressure roller to the drive shaft via a limiting ring. The heating ring heat-seals the packaging film, and the second slitting blade cuts the heat-sealed sections. This allows the device to facilitate continuous simultaneous slitting of multiple packaging units, further improving the working efficiency of the aseptic dressing packaging slitting equipment during use.
