DETAILED DESCRIPTION

[0029] 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.

[0030] See also Figure 1-6 The utility model provides a technical solution: a wire break protection device for a braiding machine, comprising a braiding machine body 1, a wire drum 2, a winding drum 3, a braiding wire 4, a guide ring 5, a lead roller 6, a limit block 7, a connecting plate 8, an infrared sensor 9, a warning device 10, a connecting column 11, a magnetic line plate 12, a rotating shaft 13, a rotating plate 14, and a clamping block 15.

[0031] Example 1

[0032] The wire break protection device of the knitting machine is provided with a wire break prompting structure. When the wire is broken, the infrared sensor 9 turns on the alarm 10 to give a prompt, specifically:

[0033] A braiding machine body 1, wherein a wire drum 2 is arranged on the upper surface of the braiding machine body 1, and further comprising a wire reel 3, which is mounted on the upper surface of the groove of the braiding machine body 1, and a braiding wire 4 is wound around the outer surface of the wire reel 3, and a wire breakage prompting structure is installed on the upper surface of the groove of the braiding machine body 1, and the wire breakage prompting structure comprises a guide ring 5, which is fixedly mounted on the upper end side surface of the wire reel 3, and a wire lead roller 6 is installed on one side of the lower end of the guide ring 5, and the upper surface of the wire lead roller 6 corresponds to the lower surface of the limiting block 7, and the wire lead roller 6 is installed on the upper surface of the groove of the braiding machine body 1 through a connecting piece, and a connecting column 11 is installed on the upper surface of the groove of the braiding machine body 1, and a connecting plate 8 is connected to the upper surface of the connecting column 11, and a slot is arranged on the upper surface of the connecting plate 8, and an infrared sensor 9 is embedded in the slot, and the infrared sensor 9 is controlled and connected with an alarm 10, and the alarm 10 is installed on the upper surface of the connecting plate 8, and the limiting block 7 corresponds to the slot arranged on the upper surface of the guide ring 5, and the limiting block 7 is arranged as a 7-shaped structure;

[0034] When the braiding machine wire breaking protection device is in use, Figure 2 As shown, the braided wire 4 wound on the outer surface of the winding drum 3 will first pass under the lead roller 6. Since the upper side of the lead roller 6 corresponds to the lower surface of the limit block 7, the braided wire 4 passes through the slot of the limit block 7 upward, and then continues upward, through the guide ring 5 installed on the upper end side surface of the winding drum 3. Through the multiple guidance of the lead roller 6, the limit block 7 and the guide ring 5, it is possible to avoid the braided wire 4 and the winding drum 3 from being quickly entangled when the wire breaks, making the braided wire 4 messy. Then the braided wire 4 passes upward through the slot of the connecting plate 8 to connect with the wire drum 2. The wire drum 2 rotates and pulls the braided wire 4, so that the braided wire 4 drives the winding drum 3 and the lead roller 6 to rotate. When the wire breaks, the infrared sensor 9 installed at the slot of the connecting plate 8 will sense it, and then the alarm 10 will be controlled to turn on, so that the staff can handle it in the first time to avoid malfunction of the device.

[0035] Example 2

[0036] The braiding machine wire break protection device is also provided with a wire break clamping structure, which drives the clamping block 15 to rotate and clamp the winding drum 3 by the rotating plate 14, specifically:

[0037] The braiding machine body 1 is also provided with a broken wire clamping structure, which can drive the clamping block 15 to clamp the broken wire and stop the winding drum 3 from rotating by controlling the rotation of the rotating plate 14. The broken wire clamping structure includes a magnetic line plate 12, which is fixedly installed on the upper surface of the groove of the braiding machine body 1, and the magnetic line plate 12 is controlled and connected with the infrared sensor 9 through a connecting column 11. The upper surface of the magnetic line plate 12 is magnetically slidably connected with the rotating plate 14, and the contact part between the rotating plate 14 and the magnetic line plate 12 is set to iron material. There are two rotating plates 14 symmetrically arranged, and the middle of the lower surface of the rotating plate 14 is rotatably connected with a rotating shaft 13, and the rotating shaft 13 is fixedly installed on the upper surface of the groove of the braiding machine body 1. The front end of the rotating plate 14 is fixedly connected with a clamping block 15, and the clamping block 15 corresponds to the outer surface of the winding drum 3, and the clamping block 15 is set to an arc structure;

[0038] The rotation of the wire reel 2 and pulling the braided wire 4 will cause the winding drum 3 to rotate. When the wire is broken, the winding drum 3 cannot stop quickly, which will cause the wire to continue to be drawn out. Therefore, when the wire is broken, since the infrared sensor 9 is controlled and connected to the magnetic line plate 12 through the connecting column 11, the magnetic line plate 12 will be opened. Since the contact portion between the rotating plate 14 and the magnetic line plate 12 is set to iron material, the magnetic line plate 12 will guide the rear ends of the two rotating plates 14 to move in opposite directions through magnetic force, so that the rotating plate 14 rotates around the rotating shaft 13, so that the arc-shaped structure clamping block 15 installed at the front end of the rotating plate 14 clamps the winding drum 3, so that the winding drum 3 stops rotating and avoids continuing to draw out the wire, which is convenient for the staff to quickly handle and avoid affecting the processing efficiency.

[0039] Working principle: When using the braiding machine wire breakage protection device, the wire breakage prompt structure can use the infrared sensor 9 when the wire breaks, and then control the alarm 10 to turn on and notify the staff; the wire breakage clamping structure can clamp the winding drum 3 by controlling the clamping block 15, so that the winding drum 3 stops rotating, thereby increasing the overall practicality.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
