[0002] During the production and processing of steel wire, the steel wire needs to be unwound online. Generally, the steel wire coil is unwound by traction force. Under the influence of transmission tension, the diameter of the steel wire coil will shrink smaller and smaller on the unwinding equipment, and may even become entangled, affecting the smooth unwinding of the steel wire. Utility Model Content

[0003] The purpose of this invention is to provide an active unwinding assembly for steel wire, which can achieve stable online unwinding of steel wire.

[0004] To achieve the above-mentioned utility model objectives, this utility model provides an active unwinding assembly for steel wire, including an unwinding mechanism and a tension adjusting mechanism, wherein the unwinding mechanism is located on the feeding side of the tension adjusting mechanism;

[0005] The unwinding mechanism includes a base, a wire unwinding reel, a support column, a support rod, and a first driving component;

[0006] The first driving component is connected to the wire feeding reel via the base, the material support column is located above the wire feeding reel, and the outer wall of the material support column is provided with a plurality of material support rods;

[0007] The tension adjustment mechanism includes a frame, a transmission wheel, an adjustment wheel, a sensing component, a transmission limit component, a driven plate, and a second driving component;

[0008] The frame is vertically provided with a connecting groove, the adjusting wheel is connected to the driven plate through the connecting groove, and the driven plate is connected to the second driving component; both sides of the adjusting wheel are provided with transmission wheels through the frame; the transmission limiting component is located on the feeding side of the frame;

[0009] The sensing assembly includes a sensing plate and a sensing element. The sensing plate is inclinedly disposed on the driven plate, and the sensing element is connected to the frame, with the sensing head of the sensing element facing the sensing plate.

[0010] As a further improvement of the utility model, the top of the wire feeding reel is provided with a mounting block, the bottom of the support column is provided with a mounting plate, the mounting plate is provided with a slot adapted to the mounting block, and the mounting plate is connected to the wire feeding reel through the slot.

[0017] This utility model discloses an active unwinding assembly for steel wire. The steel wire roll is placed on a pay-off reel. The first driving component can be an existing motor, which drives the pay-off reel to rotate continuously, actively unwinding the steel wire roll. The unwound steel wire is transferred to a transmission wheel via a transmission limiting component, which can be an existing bidirectional limiting roller assembly. This component limits the steel wire in both the longitudinal and transverse directions during transmission, preventing excessive bending of the newly unwound wire that could cause fly wire. After the steel wire is transferred to an adjusting wheel, the adjusting wheel is affected by the constantly changing tension of the online-transmitted steel wire, causing it to float up and down within the connecting groove. Simultaneously, a driven plate connected to it rises and falls. The distance between the inclined sensing plate on the driven plate and the sensing element changes. The sensing element can be an existing distance sensor, which senses the distance to the sensing plate in real time and transmits the signal to the terminal control cabinet. This sends a command to the first driving component to adjust its rotation speed, thereby adjusting the online unwinding speed of the steel wire roll in real time according to changes in steel wire tension.

[0018] The advantages of this utility model's active unwinding assembly for steel wire compared to existing technologies are as follows:

[0019] The wire coil is actively unwound, and the changes in wire transmission tension are monitored in real time by a sensing component, thereby adjusting the active unwinding speed in a timely manner to match the real-time material transfer speed required for production and processing. The tension adjustment response is faster, which solves the problem of the wire coil diameter becoming smaller during online unwinding. Attached Figure Description

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 As shown, the present invention provides an active unwinding assembly for steel wire, comprising an unwinding mechanism 1 and a tension adjusting mechanism 2, wherein the unwinding mechanism 1 is located on the feeding side of the tension adjusting mechanism 2.

[0026] like Figure 2 As shown, the unwinding mechanism 1 includes a base 11, a wire unwinding reel 12, a support column 13, a support rod 14, and a first driving component 16;

[0027] The first driving component 16 is connected to the wire feeding reel 12 via the base 11. The support column 13 is located above the wire feeding reel 12, and the outer wall of the support column 13 is provided with several support rods 14.

[0028] like Figure 3-4 As shown, the tension adjustment mechanism 2 includes a frame 21, a transmission wheel 22, an adjustment wheel 23, a sensing component 24, a transmission limit component 26, a driven plate 27, and a second driving component 28;

[0029] The frame 21 is vertically provided with a connecting groove 211, and the adjusting wheel 23 is connected to the driven plate 27 through the connecting groove 211. The driven plate 27 is connected to the second driving member 28. The adjusting wheel 23 is provided with a transmission wheel 22 on both sides of the frame 21. The transmission limiting component 26 is located on the feeding side of the frame 21.

[0030] The sensing assembly 24 includes a sensing plate 241 and a sensing element 242. The sensing plate 241 is inclinedly disposed on the driven plate 27, and the sensing element 242 is connected to the frame 21. The sensing head of the sensing element 242 faces the sensing plate 241.

[0031] This utility model discloses an active unwinding assembly for steel wire. The steel wire roll is placed on a pay-off reel 12. The first driving component 16 can be an existing motor, which drives the pay-off reel 12 to rotate continuously, actively unwinding the steel wire roll. The unwound steel wire is transferred to a transfer wheel 22 via a transfer limiting component 26. The transfer limiting component 26 can be an existing bidirectional limiting roller assembly, which limits the longitudinal and transverse directions of the wire during transmission to prevent excessive bending of the newly unwound wire, thus avoiding wire breakage. After the steel wire is transferred to an adjusting wheel 23, the adjusting wheel 23 is subjected to online transmission... The constantly changing tension of the wire causes it to float up and down within the connecting groove 211, and the driven plate 27 connected to it rises and falls simultaneously. The distance between the inclined sensing plate 241 and the sensing element 242 on the driven plate 27 changes. The sensing element 242 can be an existing distance sensor that senses the distance between itself and the sensing plate 241 in real time and transmits the signal to the terminal control cabinet, thereby issuing a command to the first drive unit 16 to adjust the rotation speed of the first drive unit 16 so as to adjust the online unwinding speed of the wire coil in real time according to the changes in wire tension.

[0032] When the wire is unwound, the support column 13 can support the inner ring of the wire roll, preventing the wire roll from being tightened or even the wire from getting tangled after continuous unwinding. The support rod 14 increases the distance between the support column 13 and the wire roll, making it easier for the wire roll to be loaded onto the support column 13.

[0033] The top of the wire feeding reel 12 is provided with a mounting block 121, and the bottom of the support column 13 is provided with a mounting plate 15. The mounting plate 15 has a slot 151 that matches the mounting block 121, and the mounting plate 15 is connected to the wire feeding reel 12 through the slot 151. The wire feeding reel 12 and the support column 13 have a detachable connection structure, and the support column 13 can be replaced with a suitable one according to the different sizes and specifications of the wire coils.

[0034] The tension adjustment mechanism 2 also includes a positioning roller 25. Both the transmission wheel 22 and the adjustment wheel 23 are equipped with positioning rollers 25. The positioning roller 25 can limit the transmission position of the steel wire. When the tension of the steel wire is out of control, the wire flying phenomenon occurs, so that the steel wire is always transmitted on the transmission wheel 22 and the adjustment wheel 23.

[0035] The sensing plate 241 is provided with a mounting part 244, and the fastener 245 detachably connects the sensing plate 241 to the driven plate 27 through the mounting part 244. The tilt of the sensing plate 241 can be adjusted according to the unwinding requirements of the wire coil and the specifications of the wire, that is, the initial sensing distance between the sensing plate 241 and the sensing element 242 can be adjusted.

[0036] The sensor 242 is provided with a protective block 243, and the protective block 243 is provided with a clearance opening 246, in which the sensor 242 is located. The protective block 243 protects the sensor 242 and prevents the tilted sensor plate 241 from going out of control and colliding with the sensor 242 during displacement.

[0037] The frame 21 is equipped with a guide rail assembly 271, which is connected to the driven plate 27. The guide rail assembly 271 can be an existing linear guide rail and slider assembly. The driven plate 27 is connected to the linear guide rail through the slider, so that the driven plate 27 always moves up and down along the same straight line, reducing the offset of the driven plate 27 and avoiding affecting the position of the adjusting wheel 23.

[0038] The frame 21 is equipped with a limit plate 212, which is located below the driven plate 27. The limit plate 212 restricts the maximum travel of the driven plate 27 during descent, preventing it from going out of control, derailing, or damaging the equipment.

[0039] The second driving component 28 serves to connect, reset, and buffer the driven plate 27. The second driving component 28 is preferably a cylinder, which facilitates machine adjustment. According to the thickness of different steel wires and unwinding requirements, the initial height of the driven plate 27, i.e. the adjusting wheel 23, can be quickly adjusted by the cylinder.
