AI Technical Summary
During the point-cutting process of surgical drapes, excessive tension may cause the drape to break and the cutting to be uneven. Existing technologies make it difficult to ensure the neatness and continuity of the cutting.
The tension on the sheet surface is adjusted by moving the unwinding roller and the receiving roller up and down. The tension is increased during point cutting to ensure a neat cut, and the tension is reduced after cutting to avoid breakage. The transmission assembly and cylinder drive the cutting piece for precise cutting.
The point-break and line cutting of surgical drapes is made more neat, misalignment is reduced, breakage is avoided, and the consistent cutting spacing is ensured each time, thereby improving processing efficiency and product quality.

Technical Field
[0001] The utility model relates to the technical field of surgical drape processing, in particular to a point breaking device for surgical drape. Background Art
[0002] Disposable bed sheets are often stored in rolls. Multiple bed sheets connected by dotted lines are rolled into a roll for storage. During the processing, it is necessary to set uniform dotted lines on the bed sheets through dotted settings to facilitate subsequent use by users.
[0003] The common point-break setting is generally set between the feed roller and the receiving roller, and the sheet stretched between the feed roller and the receiving roller is cut at a certain point. During the cutting process, it is necessary to ensure that the sheet between the feed roller and the receiving roller has a certain tension to avoid wrinkles or curling of the sheet, which may cause misalignment of the point-break line processing. However, if the tension is too large, the sheet that has been point-break cut may break at the point-break position during the receiving and unloading process, causing the processing of the device to be interrupted.
[0004] Based on this, the utility model designs a point breaking device for surgical drapes to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a point-breaking device for surgical drapes, so as to change the surface tension of the drape when feeding the drape during the processing process by moving the unwinding roller and the receiving roller up and down. After the point-breaking cutting, the unwinding roller and the receiving roller descend to reduce the tension of the drape, thereby avoiding the drape from being broken by force. When the point-breaking line of the drape is wound onto the receiving roller, the unwinding roller and the receiving roller move up to increase the surface tension of the drape, thereby making the point-breaking line cutting more neat.

[0029] See also Figure 1-Figure 5 , the utility model provides a technical solution:
[0030] A surgical drape cutting device includes a middle mounting frame 2 and side mounting frames 1 symmetrically distributed on both sides of the middle mounting frame 2. A feeding assembly is provided between the middle mounting frame 2 and the side mounting frames 1. The feeding assembly includes:
[0031] The unloading roller 7 is rotatably mounted on one side of the side mounting frame 1, and the unloading roller 7 can periodically move up and down on the side mounting frame 1;
[0032] The receiving roller 10 is rotatably mounted on the other side mounting frame 1. A transmission assembly is provided between the receiving roller 10 and the unloading roller 7. The transmission assembly can drive the receiving roller 10 and the unloading roller 7 to move up and down synchronously.
[0033] The middle roller 3 is rotatably connected between the middle mounting frame 2. One end of the surgical drape on the unwinding roller 7 passes through the lower surface of the middle roller 3 and is fixed on the receiving roller 10. A point breaking component is provided above the middle roller 3.
[0034] The limiting bent rod 6 has two groups of symmetrically arranged limiting bent rods 6, both of which are slidably connected to the middle mounting frame 2. The lower surface of the limiting bent rod 6 can contact the upper surface of the sheet on the side close to the discharge roller 7. The limiting bent rod 6 can automatically move to both sides during the upward movement of the discharge roller 7 and the receiving roller 10.
[0035] The utility model changes the surface tension of the sheet when feeding the material during the processing by moving the unloading roller 7 and the receiving roller 10 up and down. During point-break cutting, the unloading roller 7 and the receiving roller 10 move up to increase the surface tension of the sheet, ensuring that the surface of the sheet at the position of the middle roller 3 remains flat, thereby making the point-break line cutting more neat and reducing the possibility of cutting misalignment. After the point-break cutting, the unloading roller 7 and the receiving roller 10 descend to reduce the tension of the sheet, avoiding the sheet from being broken by force. When the point-break line of the sheet is wound onto the receiving roller 10, the unloading roller 7 and the receiving roller 10 are driven up again to cut again, ensuring that the spacing between the point-break lines is consistent each time.
[0036] The transmission assembly includes threaded rods 9 and sliding plates 11. Multiple sets of threaded rods 9 are provided and are rotatably mounted on both ends of the side mounting frame 1. Each threaded rod 9 is threadedly connected to a movable frame 8. The receiving roller 10 and the unloading roller 7 are rotatably connected between the movable frames 8. The threaded rods 9 rotate and interact with the movable frames 8, thereby driving the receiving roller 10 and the unloading roller 7 to move up and down.
[0037] An upper mounting plate 4 is fixedly mounted between the intermediate mounting frames 2. This upper mounting plate 4 is positioned above the intermediate rollers 3 and evenly mounted with multiple cylinders 5. Cutting elements 18 are fixedly mounted at the output ends of the cylinders 5. The cylinders 5 drive the cutting elements 18 downward, which then pass through slots 19 to cut the drape surface below the intermediate rollers 3.
[0038] The positions of the intermediate rollers 3 corresponding to the cutting pieces 18 are each provided with through slots 19, which allow the cutting pieces 18 to pass through. The threaded rods 9 at both ends of the mounting frame 1 on the same side have opposite threads, ensuring that the movable frames 8 on both sides move up and down synchronously.
[0039] The sliding plate 11 is slidably connected to both sides of the side mounting frame 1. Gears 16 are provided at both ends of the sliding plate 11. A driven gear 15 is fixedly mounted on the lower end of the threaded rod 9, meshing with the gears 16. The sliding of the sliding plate 11 drives the gears 16 to move, which in turn meshes with the driven gear 15. The rotation of the driven gear 15 drives the rotation of the threaded rod 9.
[0040] Among them, a connecting plate 12 is provided between the sliding plates 11 on both sides. A curved groove 13 is provided at both ends of the connecting plate 12. A connecting block 14 is slidably connected in the curved groove 13. The upper end of the connecting block 14 is fixedly connected to the lower end of the limiting curved rod 6. When the sliding plate 11 moves toward the discharge roller 7 to drive the discharge roller 7 and the receiving roller 10 to move upward, the connecting block 14 slides in the curved groove 13. As a result, when the discharge roller 7 and the receiving roller 10 pull the bed sheet upward, the limiting curved rod 6 also slides outward under the left and right sides of the curved groove 13. The limiting curved rod 6 limits the curling of the edge of the bed sheet, thereby partially avoiding the situation of point breakage and line misalignment.
[0041] A connecting post 17 is fixedly mounted in the middle of the connecting plate 12. An electric telescopic rod is provided at one end of the connecting post 17, which can drive the connecting post 17 to slide on the side mounting frame 1. The electric telescopic rod drives the connecting post 17 to slide, and the sliding plate 11 moves by moving the connecting post 17 toward the unloading roller 7, thereby driving the unloading roller 7 and the receiving roller 10 to move upward. After cutting, the electric telescopic rod drives the connecting post 17 away from the unloading roller 7, thereby driving the unloading roller 7 and the receiving roller 10 to move downward.
