[0002] In the prior art, for example, a utility model with publication number 202022797874.8 discloses a knife-type wire feeding card structure for a high-speed nail making machine. In order to solve the problem that the current wire feeding card lever adopts bolt positioning with poor rigidity and deformation occurs when biting the wire, resulting in inadequate locking, the present wire feeding card mechanism adopts a rotating eccentric adjusting shaft to make the bearing and the upper alloy mounting clip move up and down to adapt to wires of different diameters; the eccentric adjustable upper alloy clip assembly is positioned by the mounting shaft to increase the rigidity; the spring and the adjustable bolt are threadedly installed on the wire feeding card carrier, and the preload force is adjustable (adjusting the length of the adjustable bolt compression spring) to adapt to different wire feeding speeds.

[0003] Similar to the above application, there are still some shortcomings:

DETAILED DESCRIPTION

[0023] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0024] like Figure 1-Figure 4 As shown, this embodiment provides a knife-type wire feeding card structure, including a wire feeding card carrier plate 1, a lower alloy part 2 fixedly mounted on the bottom of the wire feeding card carrier plate 1, and an upper alloy mounting clip 3 rotatably mounted on the top of the wire feeding card carrier plate 1, one side of the top of the wire feeding card carrier plate 1 is provided with a positioning mechanism 4 for limiting the rotation angle of the upper alloy mounting clip 3, an inner screw tube 7 is installed on the other side of the top of the wire feeding card carrier plate 1, and an adjusting bolt 8 is installed on the internal thread of the inner screw tube 7, a ball 5 is rotatably mounted on the side of the top of the upper alloy mounting clip 3 close to the inner screw tube 7, a limiting rod 6 is fixedly mounted on the ball 5, the limiting rod 6 passes through the inside of the adjusting bolt 8 and is slidably connected with the adjusting bolt 8, a spring 9 is installed between the side edge of the top of the upper alloy mounting clip 3 and the end of the adjusting bolt 8, and the limiting rod 6 passes through the inside of the spring 9.

[0025] The overall working principle is as follows: during the wire conveying process, the upper alloy mounting clip 3 and the lower alloy part 2 clamp the wire for conveying during wire feeding, and the elastic force applied by the upper alloy mounting clip 3 of the spring 9 is used to ensure the clamping effect of the wire, and the rotation angle of the upper alloy mounting clip 3 is limited by the positioning mechanism 4 to ensure the clamping effect of the wire without causing excessive compression on the wire. During the wire withdrawal process, the top of the upper alloy mounting clip 3 will compress the spring 9 to a certain extent, so as to facilitate the upper alloy mounting clip 3 to move toward the rear of the wire. In addition, during the wire feeding and withdrawal process, the wire feeding clip carrier plate 1 will vibrate greatly. By using the limit rod 6 to cross the inside of the spring 9, the spring 9 can be effectively prevented from deforming outward, thereby ensuring the elastic effect and service life of the spring 9.

[0026] In this embodiment, a sliding hole 10 is opened inside the adjusting bolt 8 along the length direction, and the inner diameter of the sliding hole 10 is larger than the diameter of the limiting rod 6 .

[0027] Partial working principle: When the upper alloy mounting clip 3 squeezes the spring 9 , the limiting rod 6 will slide inside the sliding hole 10 to ensure the limiting of the spring 9 .

[0028] In this embodiment, a conical head 13 is provided at one end of the adjusting bolt 8 close to the upper alloy mounting clip 3 , and the end of the conical head 13 is inserted into the interior of the spring 9 .

[0029] Partial working principle: The conical head 13 at the end of the adjusting bolt 8 can ensure the positioning effect between the spring 9 and the adjusting bolt 8.

[0030] In this embodiment, both ends of the adjusting bolt 8 are threadedly mounted with first fastening nuts 12 , and the first fastening nuts 12 are attached to two sides of the inner screw tube 7 .

[0031] Partial working principle: After adjusting the adjusting bolt 8, tighten the first fastening nut 12 to fasten the adjusting bolt 8 to stabilize the position of the adjusting bolt 8.

[0032] In this embodiment, a rotating rod 14 is rotatably mounted on the bottom end of the inner spiral tube 7 , and one end of the rotating rod 14 away from the inner spiral tube 7 is fixedly connected to the wire feeding clamp carrier plate 1 .

[0033] Local working principle: Due to the use of the rotating rod 14, the inner screw tube 7 is rotationally connected to the wire feeding clip carrier plate 1. When the spring 9 is subjected to extrusion force, the angle of the inner screw tube 7 can be automatically adjusted to ensure that the spring 9 is subjected to force along the length direction and to avoid the spring 9 being deformed outward due to force.

[0034] In this embodiment, an arc groove 11 is formed on the side of the upper alloy mounting clip 3 , and the ball 5 is rotatably mounted inside the arc groove 11 .

[0035] Partial working principle: Since the upper alloy mounting clip 3 is rotatably mounted on the wire feeding clip carrier plate 1, the position angle of the limit rod 6 can also be adjusted as the upper alloy mounting clip 3 rotates.

[0036] In this embodiment, the positioning mechanism 4 includes a fixing block 15, a positioning bolt 16 and a second fastening nut 17. The fixing block 15 is fixed on the wire feeding clip carrier plate 1. The internal thread of the fixing block 15 is installed with the positioning bolt 16. One end of the positioning bolt 16 is threadedly installed with the second fastening nut 17, and the second fastening nut 17 is fitted with the outer side of the fixing block 15.

[0037] Partial working principle: During use, in order to limit the rotation angle of the upper alloy mounting clip 3, the positioning bolt 16 can be rotated to change the distance between the positioning bolt 16 and the upper alloy mounting clip 3, and then the second fastening nut 17 is tightened to fix the position of the positioning bolt 16.

[0038] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
