In the working process, the core wire reel needs to rotate under the traction of the core wire to realize the pay-off of the core wire. However, the above scheme often causes the core wire reel to rotate excessively due to excessive tension or inertia of the core wire, causing unstable tension, breakage or winding of the core wire.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0022] Example 1, as Figures 1-4 As shown, a natural wire release mechanism for heating wire core includes a base 1, a support frame 2 vertically mounted above the base 1, an mounting plate 3 fixedly mounted on the front side of the upper end of the support frame 2, a plurality of wire clamping components 4 provided on the front side of the mounting plate 3, and a wire spool placement plate 5 mounted on the upper surface of the base 1, with the wire spool placement plate 5 corresponding vertically to the wire clamping components 4.
[0023] The wire clamping assembly 4 includes a first wire clamping plate 41, a second wire clamping plate 42, a hollow shaft 43, and an adjusting screw 44. The first wire clamping plate 41 and the second wire clamping plate 42 are fitted together. The first wire clamping plate 41 has a first through hole 45 in the middle, and the second wire clamping plate 42 has a second through hole 46 in the middle. One end of the hollow shaft 43 passes through the first through hole 45 and the second through hole 46 in sequence and is fixedly installed on the front side of the mounting plate 3. The other end of the hollow shaft 43 is coaxially fixedly installed with a nut 47. One end of the adjusting screw 44 passes through the nut 47 and is engaged with the screw. The female 47 is threadedly connected, and the stud end of the adjusting screw 44 is movably inserted into the hollow cavity of the hollow shaft 43. The other end of the adjusting screw 44 is fixedly mounted with a knob 48. A spring 49 is fitted on the outer surface of the hollow shaft 43. One end of the spring 49 abuts against the front side of the first clamping piece 41, and the other end of the spring 49 abuts against the rear side of the knob 48. The spring 49 applies an elastic force to the first clamping piece 41 in the direction of the second clamping piece 42, so that the first clamping piece 41 and the second clamping piece 42 can cooperate to clamp the core wire.
[0024] Working principle:
[0025] In use, the core wire spool can be placed vertically on the spool placement plate 5, with the axis of the core wire spool and the inlet end of the clamping assembly 4 on the same vertical line. Then, the core wire (yarn) wound on the core wire spool is directly led out and extended upward, so that it is sequentially wound between the first clamping plate 41 and the second clamping plate 42 of each clamping assembly 4. After that, the core wire is led out and output to the next process.
[0026] When the tension of the core wire is adjusted and controlled, the knob 48 can be rotated to drive the adjusting screw 44 to rotate, so that the adjusting screw 44 moves along the axial direction thereof through the threaded connection relationship between the adjusting screw 44 and the nut 47, thereby the position of the knob 48 is adjusted and moved, the compression amount of the spring 49 is adjusted, the elastic force applied by the spring 49 to the first clamping piece 41 is adjusted, and then the clamping force between the first clamping piece 41 and the second clamping piece 42 can be controlled, thereby the adjustment and control effect of the tension of the core wire is realized. (That is, when the tension of the core wire needs to be increased, the knob 48 can be rotated to move the adjusting screw 44 to the hollow shaft 43, thereby the compression amount of the spring 49 is increased, the elastic force applied by the spring 49 to the first clamping piece 41 is increased, and then the clamping force between the first clamping piece 41 and the second clamping piece 42 is increased, thereby the tension of the core wire is effectively increased. Similarly, when the tension of the core wire needs to be reduced, the knob 48 can be rotated to move the adjusting screw 44 away from the hollow shaft 43, thereby the elastic force applied by the spring 49 to the first clamping piece 41 is reduced, and then the clamping force between the first clamping piece 41 and the second clamping piece 42 is reduced, thereby the tension of the core wire is reduced.)
[0027] In the embodiment, the core wire tension is effectively controlled by the clamping assembly 4, and the core wire reel is directly placed vertically on the reel placing plate 5, and the core wire reel does not need to be rotated during the unwinding process. Therefore, the problems of breakage and loose winding of the core wire caused by excessive stretching or rotation of the core wire reel after the core wire is unwound can be effectively avoided. In addition, the clamping force of the core wire can be adjusted by the plurality of clamping assemblies 4, so that appropriate clamping force can be given to different core wires to meet the needs of different core wires with different tensions. At the same time, the uniformity and continuity of the core wire during unwinding can be effectively ensured.

At the same time, the uniformity and continuity of the core wire during unwinding can be effectively ensured.
[0029] In the third embodiment, as a further preferred solution of the first embodiment, the upper surface of the bobbin placing plate 5 is vertically provided with a winding-off arm 7, which is arranged in vertical alignment with the wire inlet hole 61. Thus, when placing the bobbin, the bobbin can be directly inserted onto the outer surface of the winding-off arm 7, so that the central axis of the bobbin is aligned with the central axis of the winding-off arm 7, thereby achieving the radial limiting effect on the bobbin and enabling quick positioning and placing of the bobbin, so that the central axis of the bobbin is in vertical alignment with the wire inlet hole 61, and the wire head of the bobbin can be directly led upward, thereby effectively ensuring the stability of the wire unwinding of the bobbin.
[0030] In the fourth embodiment, as a further preferred solution of the third embodiment, the outer surface of the winding-off arm 7 is surrounded by a guide slope 8 at the upper end. Thus, when the bobbin is inserted onto the winding-off arm 7, the guide slope 8 can be used to guide the bobbin.
[0031] In the fifth embodiment, as a further preferred solution of the third embodiment, the winding-off arm 7 is movably sleeved with a limiting pressing ring 9. The limiting pressing ring 9 can limit the axial direction of the bobbin, thereby avoiding the movement of the bobbin along the winding-off arm 7.
[0032] In the sixth embodiment, as a further preferred solution of the first embodiment, the rear side of the first wire clamping piece 41 is coaxially provided with a plug-in column 10, which is plugged into the second through hole 46. Thus, the plug-in column 10 can be used to limit the relative position of the first wire clamping piece 41 and the second wire clamping piece 42, thereby ensuring the stable fitting between the first wire clamping piece 41 and the second wire clamping piece 42.

Although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalent ones. Such modifications or replacements do not change the essence of the corresponding technical solutions, and thus fall within the scope of the technical solutions of the embodiments of the present application.
