Detailed Implementation
[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] Please see Figures 1-2 and 5- Figure 6 A tool for forming and manufacturing perforated towels for infusion port maintenance, including a processing table 1 and a perforation forming mechanism 3 located above the processing table 1;
[0029] The hole forming mechanism 3 includes a ring cutter 31 and multiple radial cutters 32 fixed around the ring cutter 31. The ring cutter 31 has a ring structure and a wall sealing its top opening. The ring cutter 31 is used to make holes in the pore cloth, and the radial cutters 32 are used to radially cut the edges of the holes. The radial cutters 32 have a straight structure and are arranged radially along the ring cutter 31, which facilitates subsequent folding of the hole edges and fixing them by adhesive or sewing to form a reinforced edge. The diameter of the ring cutter 31 is 2.0 cm, and the length of the radial cutter 32 is 0.5 cm to adapt to the size of the injection unit.
[0030] A needle 33 is located in the middle of the circumferential cutting blade 31. The top of the needle 33 is fixed to the top wall of the circumferential cutting blade 31, and the bottom end of the needle 33 extends out from the bottom opening of the circumferential cutting blade 31. The needle 33 is hollow and has a hole 331 on its bottom side wall. The hole 331 is located below the circumferential cutting blade 31. An air bladder 332 is installed in the hole 331, and the air inlet of the air bladder 332 faces the inner cavity of the needle 33. When the circumferential cutting blade 31 moves down to make a hole in the fresco, the needle 33 passes through the multiple layers of fresco. This allows the fabric inside the cut hole to be pierced and carried by the needle 33. When multiple layers of opening are completed, the hole 331 moves to the bottom of the multi-layer fresco. At this time, by inflating the needle 33, the air bladder 332 inflates out of the hole 331. The air bladder 332 is located below the cut fabric, which restricts the fabric inside the cut hole, so that the cut fabric can be brought out when the circumferential cutter 31 is lifted. The fabric brought out is retracted again by the air bladder 332, releasing the restriction and making it easy to remove the fabric.
[0031] A deep hole 11 is provided on the processing table 1 directly below the needle 33. The inner diameter of the deep hole 11 is larger than the diameter of the needle 33, which facilitates the smooth insertion of the needle 33 and prevents the airbag 332 from colliding with the inner wall of the deep hole 11 when it inflates out of the hole 331.
[0032] Please see Figures 1-2 The tool for forming and manufacturing perforated towels for infusion port maintenance has a vertical frame 12 fixed on the processing table 1, and a telescopic rod 2 is fixed at the top of the vertical frame 12 extending to the top of the processing table 1. The top wall of the ring cutter 31 is fixed on the telescopic end of the bottom side of the telescopic rod 2, and the ring cutter 31 is raised and lowered by telescopic rod 2.
[0033] Please see Figure 1 The tool for forming and manufacturing perforated towels for infusion port maintenance is provided on the processing table 1, which is equipped with a gas inflator (using existing technology), such as an electrically controlled air inflator. The gas inflator is connected to the top of the needle 33 through a hose 34.
[0034] The inflation and deflation of the airbag 332 is controlled by an electronically controlled inflator.
[0035] Please see Figures 4-7This is a tool for forming and manufacturing perforated cloths for infusion port maintenance. A vertical rod 4 slides through the top wall of the circumferential cutter 31, and the bottom end of the vertical rod 4 is fixedly connected to a push plate 5 that is slidably disposed inside the circumferential cutter 31. At the same time, a spring 6 connects the top end of the vertical rod 4 to the top wall of the circumferential cutter 31. The push plate 5 is slidably sleeved on the needle 33. The elastic support of the push plate 5 is achieved through the cooperation of the spring 6 and the vertical rod 4. When the circumferential cutter 31 moves down to open the hole, the push plate 5 contacts the fabric to be cut and moves up with the fabric, so that the cut fabric is collected in the inner cavity of the circumferential cutter 31. When the airbag 332 is de-inflated, the airbag 332 retracts back into the hole 331. Since the limit is removed, the push plate 5 is pushed down by the rebound of the spring 6 to push out the fabric carried by the needle 33.
[0036] Please see Figures 2-3 The tool for forming and manufacturing perforated towels for infusion port maintenance includes a positioning ring 7 slidably fitted on a ring cutter 31. The inner wall of the positioning ring 7 has a notch 71 that matches the radial cutter 32, allowing the radial cutter 32 to slide in the notch 71. A spring 9 is connected between the positioning ring 7 and the top ring 8 fixedly fitted on the top of the ring cutter 31. The spring 9 pushes the positioning ring 7 to contact the perforated towel before the ring cutter 31 moves down, thus positioning and pressing the multi-layered perforated towel. As the ring cutter 31 and the radial cutter 32 cut in, the positioning ring 7 is in a stationary state and gradually compresses the spring 9.
