Description

Technical Field

[0001] This utility model relates to the field of medical gauze production technology, specifically to a medical gauze slitting machine. Background Technology

[0002] Medical gauze slitting machines are used to cut medical gauze into several strips. These machines have a mounting shaft with multiple blades, typically ring-shaped, that are fitted onto the outside of the shaft. Since the blades are usually fixed to the mounting shaft, adjusting the blade spacing or replacing blades requires disassembling the entire shaft, which affects the efficiency of adjustment and disassembly. Furthermore, medical gauze slitting machines usually contain two sets of mounting shafts, and the blades on these shafts can only slit single-roller medical gauze, resulting in low slitting efficiency.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] The double-roller medical gauze feeding system is set up, as shown in the attached document. Figure 1 and attached Figure 2As shown, a medical gauze slitting machine includes a worktable 1, a support frame 2 mounted on the lower side of the worktable 1, and gauze conveying and winding assemblies mounted on both sides above the worktable 1. Each gauze conveying and winding assembly includes two sets of feeding rods 3 and two sets of receiving rods 4. The feeding rods 3 and receiving rods 4 are rotatably mounted on the worktable 1 and symmetrically distributed on both sides of the cutter mounting assembly. Positioning receiving platforms 5 are mounted on the lower outer sides of the feeding rods 3 and receiving rods 4, and limit covers 6 are mounted on their tops. The machine includes a winding wheel containing medical gauze and an empty winding wheel. The feeding rod 3 and the take-up rod 4 are respectively vertically sleeved on the outside. The take-up wheel is provided with a rod on the lower side and inserted into the insertion hole in the positioning receiving platform 5. The upper end of the take-up wheel is limited by the limiting cover 6 to ensure the stability of the take-up wheel. Two sets of motors 7 are installed on the lower side of the worktable 1 and connected to the shaft end of the take-up rod 4. The motors 7 drive the take-up rod 4 to rotate, and the take-up rod 4 drives the empty take-up wheel to rotate, so as to roll up the cut medical gauze and move the gauze above the worktable 1. The take-up wheel is composed of multiple spliced ​​sets. After winding the cut medical gauze, it can be separated.

[0030] As attached Figure 1 Appendix Figure 4 and attached Figure 5 As shown, multiple sets of cutters 13 are installed above the middle of the workbench 1. Three sets of cutter mounting assemblies for mounting multiple sets of cutters 13 are provided above the middle of the workbench 1. Each cutter mounting assembly includes a mounting shaft 8 and multiple sets of mounting blocks 9. The multiple sets of mounting blocks 9 are equidistantly sleeved on the outside of the mounting shaft 8. Multiple sets of mounting grooves 10 are provided on the side wall of the mounting block 9. The back of the cutter 13 is integrally formed with an arc-shaped connecting plate 14. Multiple sets of positioning through holes 15 are provided on the arc-shaped connecting plate 14. Multiple sets of positioning through holes 11 are provided on the upper and lower side walls of the mounting groove 10. The arc-shaped connecting plate 14 is inserted into the mounting groove 10. The positioning through holes 15 and 11 are aligned and a positioning bolt 12 passes through them. The cutter 13 is fixedly installed inside the set of mounting grooves 10 on the side wall of the mounting block 9 by threaded connection.

[0031] The mounting groove 10 has an annular structure. The side wall of the arc-shaped connecting plate 14 fits against the inner wall of the mounting groove 10, and the blades are located on the same side. The three sets of cutting blade mounting assemblies are on the same straight line. The middle set of cutting blade mounting assemblies is fixedly connected to the worktable 1, and the two sets of cutting blade mounting assemblies on both sides are rotatably connected to the worktable 1. By rotating the two sets of mounting shafts 8 on both sides, the multiple sets of cutting blades 13 on both sides are brought closer to the inner cutting blade 13 and staggered vertically. The medical gauze passes through the angle between the two sets of staggered cutting blades 13 and is cut.

[0032] Example 2

[0033] Based on Embodiment 1, in order to facilitate bringing the multiple sets of cutters 13 on both sides closer to the inner cutter 13, a rotating assembly is connected between the lower sides of the two sets of cutter mounting assemblies that are rotatably connected to the worktable 1. The rotating assembly includes an electric rotating assembly and a manual rotating assembly.

[0034] As attached Figure 2 As shown, the electric rotating assembly includes two sets of gears 16, which are respectively mounted on the lower ends of two sets of mounting shafts 8. An L-shaped frame 17 is mounted on the lower side of the worktable 1, and a second motor 18 is mounted on the lower side of the L-shaped frame 17. The shaft end of the second motor 18 is connected to the shaft of one set of gears 16. A control switch 19 connected to the second motor 18 is mounted on one side of the worktable 1. The second motor 18 is started by the control switch 19, which drives the first set of gears 16 to rotate. The two sets of gears 16 mesh, causing the two sets of gears 16 and the mounting shafts 8 to rotate in opposite directions at the same time. This causes multiple sets of cutters 13 on both sides to move closer to the inner cutter 13. The locking structure at the shaft end of the second motor 18 positions the multiple sets of cutters 13 on both sides.

[0035] As attached Figure 3 As shown, the manual rotation assembly includes two sets of handwheels 20, which are respectively installed at the lower ends of two sets of mounting shafts 8. The eccentric part of each handwheel 20 passes through a limiting bolt 21 and is connected by a thread. The lower side of the worktable 1 is provided with multiple sets of insertion holes 22 for inserting the limiting bolts 21. Rotating the two sets of handwheels 20 respectively drives the mounting shafts 8 to rotate, bringing the multiple sets of cutters 13 on both sides closer to the inner cutter 13. Rotating the limiting bolts 21 inserts the top of the limiting bolts 21 into the corresponding insertion holes 22, thereby limiting the handwheels 20 and positioning the multiple sets of cutters 13 on both sides.
