Description
Technical Field
[0001] The utility model relates to the technical field of braiding machines, in particular to a braiding machine bobbin fixing device. Background Art
[0002] A knitting machine refers to a special mechanical equipment used for knitting processing. It can be divided into sweater knitting machines, glove knitting machines, wire knitting machines, screen knitting machines, etc. The knitting machine is suitable for a wide variety of raw materials. When the knitting machine is working, the wire needs to be removed from the bobbin fixed on the bobbin fixing device, and then the knitting process is carried out.
[0003] There are two main types of braiding machine wire bobbin fixing devices currently available on the market: rotatable and completely fixed. The rotatable wire bobbin rotates on a fixed rod, which causes the wire bobbin to be placed unstable when the wire is pulled. The completely fixed wire bobbin just fits on the outer surface of the fixed rod. When the braiding machine is working, this method can easily cause the wire to be pulled unsmoothly, thereby reducing work efficiency. Utility Model Content

[0011] A further improvement of the technical solution of the utility model is that the rotating unit includes a rotating groove opened inside the right side of the top of the weaving table, and a limiting ring plate is fixedly installed at the notch of the rotating groove. The limiting ring plate fits and abuts against the top four sides of the rotating chassis. The rotating chassis drives the wire reel to rotate inside the rotating groove, thereby promoting smooth pulling of the weaving line.
[0012] A further improvement of the technical solution of the utility model is that a cavity is opened in the middle position of the outer surface of the rotating chassis, and rotating vertical rods are fixedly installed on the upper and lower ends of the cavity.

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Example 1
[0026] like Figure 1-5 As shown, the utility model provides a braiding machine bobbin fixing device, including a braiding machine body 1, the braiding machine body 1 includes a braiding table 2, a traction bracket 3 is fixedly installed on the rear end of the top left side of the braiding table 2, a traction wire hole 31 is opened on the top of the traction bracket 3, a fixing unit is arranged on the top right side of the braiding table 2, and a rotating unit is arranged inside the right side of the braiding table 2 below the fixing unit.
[0027] Example 2
[0028] like Figure 1-5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the fixing unit includes a fixing rod 23 arranged on the right side of the top of the weaving table 2, and an arc-shaped plate 24 is fixedly installed on the top of the outer surface of the fixing rod 23, and a bearing rod 25 is fixedly installed inside the arc-shaped plate 24, and a contact plate 26 is rotatably sleeved on the outer surface of the bearing rod 25, and a rubber protrusion 27 is fixedly installed on the outer surface of the other end of the contact plate 26, and a reset spring 28 is fixedly installed on the inner surface of the other end of the contact plate 26, and the other end of the reset spring 28 is fixedly installed on the outer surface of the bottom end of the fixing rod 23, and a rotating chassis 29 is fixedly installed on the bottom end of the fixing rod 23, and the top of the weaving table 2 is located on the outer surface of the fixing rod 23, and a wire drum 21 is detachably sleeved, and a braiding wire 22 is movably sleeved on the outer surface of the wire drum 21, and the other end of the braiding wire 22 is movably inserted into the inside of the traction wire hole 31.
[0029] Furthermore, by sleeved the wire spool 21 on the outer surface of the fixing rod 23, the bottom end of the wire spool 21 gradually moves downward. At this time, the contact plates 26 on all sides are subjected to extrusion force, and the top thereof rotates on the outer surface of the bearing rod 25, and the bottom thereof moves inward to squeeze the reset spring 28 until the wire spool 21 is completely fitted on the top of the rotating chassis 29. At this time, the contact plate 26 rebounds under the elastic reverse thrust of the reset spring 28, and then contacts the inner wall of the wire spool 21 to fix it. The friction between the two can be enhanced by using the rubber bump 27, thereby further improving the stability of the wire spool 21.
[0030] Example 3
[0031] like Figure 1-5 As shown, on the basis of Examples 1-2, the utility model provides a technical solution: preferably, the rotating unit includes a rotating groove 210 opened on the inner right side of the top of the weaving table 2, and a limiting ring plate 211 is fixedly installed at the notch of the rotating groove 210, and the limiting ring plate 211 fits and abuts against the top four sides of the rotating chassis 29, and a cavity 291 is opened in the middle position of the outer surface of the rotating chassis 29, and a rotating vertical rod 292 is fixedly installed on the upper and lower ends of the cavity 291, and a roller 293 is rotatably sleeved on the outer surface of the rotating vertical rod 292, and the roller 293 rolls on the inner wall of the rotating groove 210.
[0032] Furthermore, during the weaving process, the braiding wire 22 is pulled, causing the wire reel 21 to rotate, thereby driving the rotating chassis 29 to rotate inside the rotating groove 210, and the limiting ring plate 211 can prevent the rotating chassis 29 from leaving the rotating groove 210. When the rotating chassis 29 rotates, the roller 293 is caused to rotate by friction, thereby improving the smoothness of the rotation of the rotating chassis 29.
[0033] The working principle of the braiding machine spool fixing device is described in detail below.
[0034] like Figure 1-5 As shown, when in use, the wire drum 21 is sleeved on the outer surface of the fixing rod 23 so that its bottom end gradually moves downward. At this time, the contact plates 26 around it are subjected to extrusion force, and its top rotates on the outer surface of the bearing rod 25, and its bottom moves inward to squeeze the return spring 28 until the wire drum 21 is completely attached to the top of the rotating chassis 29. At this time, the contact plate 26 rebounds under the elastic reverse thrust of the return spring 28, and then contacts the inner wall of the wire drum 21 to fix it. The friction between the two can be enhanced by using the rubber protrusion 27, and further To improve the stability of the bobbin 21, after fixing it, one end of the braiding wire 22 on the outer surface of the bobbin 21 is inserted into the inside of the traction wire hole 31 and then connected to the needle of the braiding machine to perform weaving. During the weaving process, the braiding wire 22 is pulled to cause the bobbin 21 to rotate, thereby driving the rotating chassis 29 to rotate inside the rotating groove 210. The limiting ring plate 211 can prevent the rotating chassis 29 from escaping from the rotating groove 210. When the rotating chassis 29 rotates, the roller 293 is caused to rotate due to friction, thereby improving the smoothness of the rotation of the rotating chassis 29.
[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
