[0032] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0033] like Figures 1 to 4 As shown, Figure 1 This is a schematic diagram of the overall structure of the suture thread winding device provided in an embodiment of the utility model. Figure 2 This is a schematic diagram of the top view of the suture thread winding device provided in an embodiment of the utility model.

[0034] Embodiment 1:

[0035] The suture winding device provided in this embodiment is applied to the production and processing scenarios of sutures, and is suitable for sutures that are prone to breakage, such as monofilament sutures. By improving the structure of the suture winding device in this embodiment, the suture winding efficiency can be improved while ensuring the quality of the sutures, thereby improving the production efficiency.

[0036] like Figure 3 and Figure 4 As shown, the suture thread winding device in this embodiment includes a recovery roller body 100, an elastic support portion 200 and an arc-shaped protrusion 300, and the material of the elastic support portion 200 is not limited, and includes but is not limited to rubber columns, etc.; the recovery roller body 100 can rotate around its axis; the number of the elastic support portions 200 is multiple, and the multiple elastic support portions 200 are arranged at intervals around the rotation direction of the recovery roller body 100, and the elastic support portion 200 at least partially protrudes from the recovery roller body 100; the number of the arc-shaped protrusion 300 is multiple, and is arranged between any two elastic support portions 200, that is, a plurality of arc-shaped protrusions 300 are provided between any two elastic support portions 200, and the arc-shaped protrusion 300 at least partially protrudes from the recovery roller body 100, and does not protrude from the elastic support portion 200. Exemplarily, the number of the elastic support parts 200 in this embodiment is four. When the suture is wound around the recovery roller body 100, it is divided into four sections and is wound around the recovery roller body 100 in sequence. At this time, each section of the suture is tensioned on at least two elastic support parts 200, and the elastic support parts 200 provide elastic support, thereby providing more uniform tension for each section of the suture. At the same time, for each section of the suture, there is at least one arc-shaped protrusion 300 as a support for the middle part, so that the support area of ​​the suture is increased, thereby reducing the unit area pressure of the suture.

[0037] The suture winding device provided in the present embodiment applies a more uniform tension to the suture by the elastic support portion 200 during the process of the recovery roller body 100 rotating to recover the suture. At this time, the suture is wound around the recovery roller body 100 in a polygonal shape, and the arc-shaped protrusion 300 serves to increase the contact area of ​​the suture and reduce the unit area pressure of the suture. Therefore, the winding device and suture processing equipment in the present scheme can reduce the local tension on the suture, making the suture less likely to break, and further, under the premise of maintaining the quality of the suture, the rotation speed and torque of the recovery roller body 100 can be increased, thereby improving the production efficiency and production quality of the suture winding device and the suture processing equipment.

[0038] Furthermore, the elastic support part 200 is extended along the axis and protrudes from one end of the recycling roller body 100, and the ends of the elastic support parts 200 protruding from the recycling roller body 100 are connected to each other; the other end of the recycling roller body 100 is fixedly connected to the driving roller part 110, and the driving roller part 110 is used to be driven to rotate. Among them, the elastic support parts 200 are connected to each other, which can effectively disperse the pressure and tension generated during the winding process, reduce the bending or deformation caused by uneven load, and improve the production quality.

[0039] Further, the elastic support part 200 is slidably connected with the recovery roller body 100 along the axis, and a telescopic part 120 is installed at one end of the recovery roller body 100, and the telescopic end of the telescopic part 120 can move along the axis; wherein, the elastic support part 200 protrudes from one end of the recovery roller body 100 and is connected to the telescopic end, and the telescopic part 120 can select a structure such as a cylinder, a lifting motor, etc., and can adjust the position of the elastic support part 200 relative to the recovery roller body 100. It can be understood that through the above arrangement, the suture can be evenly wound on the elastic support part 200. For example, after the suture is wound around the first position of the elastic support part 200, the position of the elastic support part 200 is adjusted so that the second circle of the suture is wound around the second position of the elastic support part 200. The first position and the second position are adjacently arranged, and so on, that is, the amount of expansion and contraction of the telescopic part 120 each time is the same as the diameter of the suture, thereby evenly winding the suture around the elastic support part 200, thereby improving the stability of winding.

[0040] Specifically, Figures 1 to 4 As shown, two fixed side ribs 130 are installed outside the recovery roller body 100, and a winding gap 140 is left between the two fixed side ribs 130; a movable side rib 400 is also provided in the winding gap 140, and the movable side rib 400 is installed on the elastic support part 200, and a movable gap 150 is left between the movable side rib 400 and the fixed side rib 130 close to one end of the recovery roller body 100, that is, the suture thread is wound in the movable gap 150. It can be understood that as the winding proceeds, the movable gap 150 gradually increases, thereby facilitating the suture thread to be evenly wound around the elastic support part 200.

[0041] Specifically, the movable retaining edge portion 400 includes a movable base plate 410 installed on the elastic support portion 200, a limiting portion 420 is protruding from the movable base plate 410, and a limiting groove 421 is provided in the limiting groove 421; a movable baffle 430 is movably connected along the axis in the limiting groove 421, and the movable baffle 430 can move between the groove wall of the limiting groove 421 and the movable base plate 410, and a spring unit is provided between the movable baffle 430 and the movable base plate 410, and the spring unit (not shown) is respectively abutted against the movable baffle 430 and the movable base plate 410; a limiting baffle 440 is also connected to the side of the movable baffle 430 away from the movable base plate 410, and the limiting baffle 440 at least partially protrudes from the limiting portion 420. Through the above arrangement, when the thickness of the movable gap 150 is zero, the movable base plate 410 can abut against the fixed retaining edge 130 on one side through the spring unit, the movable baffle 430 and the limiting baffle 440, thereby playing a buffering role and improving the stability of the device.

[0042] Based on the above embodiment, the elastic support part 200 includes a cylindrical support column 210 , and an arc groove 160 is opened on the outer wall of the recovery roller body 100 at a position corresponding to the support column 210 , and the support column 210 is at least partially located in the arc groove 160 .

[0043] On the basis of the above-mentioned embodiment, the end of the support column 210 protruding from the recovery roller body 100 is connected with an arc-shaped connecting portion 220 , and a plurality of arc-shaped connecting portions 220 are connected to each other and installed on the telescopic end through a connecting block.

[0044] In summary, the suture thread winding device provided in this embodiment has the advantages of high production efficiency, high production quality, and high stability.

The processing device can be a coating device, a dyeing device, etc., which are well known to those skilled in the art and will not be specifically expanded; the suture can be released from the unwinding device, and after being processed by the processing device, it can be rewound by the suture winding device. Embodiment 1 describes the specific structure and technical effects of the suture winding device. The suture processing equipment in this embodiment quotes this structure and also has the same technical effects.

[0047] In summary, the suture processing equipment provided in this embodiment has the advantages of high production efficiency, high production quality, and high stability.
