Description

Technical Field

[0001] This utility model belongs to the field of medical dressing production technology, and specifically relates to a drying device for X-ray imaging gauze. Background Technology

[0002] Gauze is widely used in medical surgeries as a disposable medical dressing due to its high absorbency, low cost, and ease of disposal. However, some surgeries, especially major surgeries such as abdominal surgeries, involve the extensive use of gauze to absorb blood or other bodily fluids. Used gauze is difficult to separate from the patient's internal tissues and can easily remain inside the patient's body undetected, causing significant pain and even endangering their life.

[0003] In existing technologies, an X-ray tracking line that can be detected by X-ray equipment is attached or woven into medical fabric. This allows for accurate location and removal of the gauze even in the event of an accident, ensuring the patient's health. Currently, the X-ray tracking line is made of barium sulfate blended with other non-toxic yarns, such as cotton or synthetic fibers. The preparation process of X-ray imaging gauze typically includes: weaving the gauze and embedding the X-ray tracking line, degreasing and bleaching (in large rolls), drying, and slitting. Drying and slitting are usually performed using the same equipment.

[0004] For example, patent application number CN201320085363.0 discloses a drying, slitting, and winding integrated machine, including: an unwinding device for unwinding strip material; a drying cylinder device for drying the strip material, the drying cylinder device being disposed after the unwinding device; a pressure-cutting slitting device, the pressure-cutting slitting device being disposed after the drying cylinder device, which includes at least one slitting blade capable of slitting the strip material into at least two sub-material strips; and a winding device, the winding device including at least two sets of winding mechanisms for winding the sub-material strips respectively.

[0005] For example, patent application number CN201721421167.0 discloses a three-roller dryer for nonwoven fabric, including a frame and an unwinding device, a correction device, an annular transfer roller, a first reversing roller, a heating roller, a pressing device, a second reversing roller, a cooling device, and a winding device arranged on the frame; both the unwinding device and the winding device are equipped with correction devices; an annular transfer roller is arranged on the right side of the unwinding device; a first reversing roller is arranged on the right side of the annular transfer roller; a heating roller is arranged on the right side of the first reversing roller; a pressing device is arranged on the heating roller to compress the nonwoven fabric wound on the heating roller; a second reversing roller is arranged on the right side of the heating roller; a cooling device is arranged on the right side of the second reversing roller; and a winding device is arranged on the right side of the cooling device; the heating roller includes a first heating roller, a second heating roller, and a third heating roller; the first heating roller, the second heating roller, and the third heating roller are arranged in an inverted triangular shape on the frame.

[0006] For example, patent application number CN202222624631.3 discloses a continuous production line for impregnating and drying carbon felt, including a dual-station unwinding mechanism, a cutting and splicing mechanism, a material changing and buffering mechanism, an impregnation and gluing mechanism, and a drying mechanism connected in sequence. The dual-station unwinding mechanism includes two unwinding rollers, which are used to continuously transport multiple carbon felt raw material rolls to the cutting and splicing mechanism. The cutting and splicing mechanism is used to connect two continuously passing carbon felt raw material rolls. The material changing and buffering mechanism includes two spaced-apart limiting rollers and a buffer roller located between the two limiting rollers. The buffer roller is movable relative to the two limiting rollers to facilitate bending the carbon felt raw material located between the two limiting rollers.

[0007] During actual production, the applicant discovered that the thickness of the gauze increases at the location where the X-ray imaging line is implanted. When the gauze is wound, it is wound in hundreds of layers, so the area with the X-ray imaging line becomes thicker than other areas. As the gauze roll gradually increases in size, the area with the X-ray imaging line gradually bulges, which stretches the gauze, causing the gauze to deform or the yarn to break. Summary of the Invention

[0008] To address the aforementioned problems, this utility model provides a drying device for X-ray developing gauze. After the flattening rollers distribute and flatten the gauze, the device swings the gauze back and forth, continuously adjusting the X-ray developing lines left and right to stagger them, thereby preventing the gauze with X-ray developing lines from stacking and thickening in the same position. The technical solution is as follows:

[0015] Furthermore, the traction structure 7 in this embodiment of the present invention also includes a cylinder, two columns and two slides. The third traction roller 71 is mounted on the frame of the slitting structure 6.
