Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical dressings, and in particular relates to production equipment for medical dressings. Background Art
[0002] Hydrophilic dressings are playing an increasingly important role in wound care, particularly those that effectively maintain a moist wound environment, promote healing, and reduce the risk of infection. Carboxymethylcellulose (CMC), due to its excellent biocompatibility, moisture retention, and cell growth-promoting properties, is an ideal material for hydrophilic dressings. Hydrophilic dressings are highly absorbent, equivalent to 4-5 times that of six layers of gauze. They absorb and lock in exudate, forming a gel that provides a moist wound healing environment.
[0003] CMC dressings require a special sewing method to increase their structural stability and need to be cut into appropriate sizes before use. In the existing technology, the production process of medical dressings usually requires multiple steps for compounding and cutting materials, which is inefficient. Summary of the Invention
[0004] The technical problem to be solved by the utility model is to provide a production equipment for medical dressings. By integrating a first unwinding device, a second unwinding device, a sewing machine, a longitudinal slitting device, a bonding machine and a transverse slitting machine, one-time compounding and slitting of the dressing is achieved, thereby greatly improving production efficiency.
[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:
[0006] A medical dressing production device includes a first unwinding device and a second unwinding device. The first unwinding device and the second unwinding device are equipped with a sewing machine at the rear end of the process, and the sewing machine is used to sew the dressings on the first unwinding device and the second unwinding device; the sewing machine is equipped with a longitudinal slitting device at the rear end of the process, and the longitudinal slitting device is equipped with a bonding machine and a transverse slitting machine in sequence at the rear end of the process.
[0007] Preferably, the first unwinding device, the second unwinding device, the sewing machine, the longitudinal slitting device, the bonding machine and the transverse slitting machine are all installed on the frame, and an operator's work station is provided between the first unwinding device and the second unwinding device.
[0008] Preferably, the first unwinding device unwinds the material from below the operator's work station, and the second unwinding device unwinds the material from obliquely above the operator's work station.
[0009] Preferably, the bobbin rack of the sewing machine is installed above or obliquely above the operator's work station.
[0010] Preferably, the first unwinding device and the second unwinding device are both equipped with an automatically adjusting tension swing frame.
[0011] Preferably, the transverse slitting machine is installed at the end of the frame and arranged opposite to the first unwinding device, and the bonding machine is located in the middle of the frame.
[0012] The utility model can achieve the following beneficial effects:
[0013] Existing finished dressings are whole pieces, requiring users to cut them again before use, which is inconvenient. The present invention uses a bonding machine to recompact the dressing, significantly reducing the appearance of hairiness and small thread ends after slitting, preventing them from falling onto wounds during use, particularly ulcers or cavitary wounds, where they are difficult to find and clean. By integrating a first unwinding device, a second unwinding device, a sewing machine, a longitudinal slitting device, a bonding machine, and a transverse slitting machine, the dressing is laminated and slit into shape in one go, significantly improving production efficiency.

DETAILED DESCRIPTION
[0019] The preferred solution is Figures 1 to 3 As shown, a medical dressing production device includes a first unwinding device 1 and a second unwinding device 2. A sewing machine 3 is installed at the rear end of the process of the first unwinding device 1 and the second unwinding device 2. The sewing machine 3 is used to sew the dressings on the first unwinding device 1 and the second unwinding device 2; a longitudinal slitting device 4 is installed at the rear end of the process of the sewing machine 3, and a bonding machine 5 and a transverse slitting machine 6 are sequentially provided at the rear end of the process of the longitudinal slitting device 4.

The gel-forming fibers include spun cellulose fibers, chemically modified cellulose fibers, pectin fibers, alginate fibers, chitosan fibers, hyaluronic acid fibers, other polysaccharide fibers, and gum-extending fibers.
[0021] This device can compound and cut (including cross-cutting and longitudinal cutting) CMC dressing into shape at one time, reducing the problems of hairiness and thread ends that are prone to occur after cutting.
[0022] Preferably, the first unwinding device 1, the second unwinding device 2, the sewing machine 3, the longitudinal slitting device 4, the bonding machine 5 and the transverse slitting machine 6 are all installed on the frame, and an operator workstation 7 is provided between the first unwinding device 1 and the second unwinding device 2.
[0023] The operator's workstation 7 is used to provide an operating platform for the operator, and the operator operates the sewing machine 3 to sew the composite double-layer material.
[0024] In this embodiment, the first unwinding device 1 unwinds the material from below the operator's work station 7, and the second unwinding device 2 unwinds the material from obliquely above the operator's work station 7. In this way, the unwinding material will not cause interference to the operator. In addition, if Figure 1 As shown, the bobbin frame 8 of the sewing machine 3 is installed above or obliquely above the operator's work station 7. The transverse slitting machine 6 is installed at the end of the frame and arranged opposite to the first unwinding device 1, and the bonding machine 5 is located in the middle of the frame.
