DETAILED DESCRIPTION

[0026] In order to further understand the features, technical means and specific purposes and functions achieved by the utility model, the utility model will be described in further detail below in combination with the drawings and specific embodiments

[0027] See Figures 1-8As shown in the figure, the anti-rotation wire pressing device for transformer winding includes a wire rack 1, a wire feeding device 3 arranged on the wire rack 1 and capable of rotating, a check mechanism 32 arranged at the bottom of the wire rack 1 and used for preventing the wire feeding device 3 from rotating, and a wire feeding roller 6 arranged at the top of the wire feeding device 3 and used for feeding wire. The wire feeding device 3 includes a rotating table 31 rotatably arranged on the wire rack 1. The rotating table 31 is provided with a first insertion rod 311 capable of being inserted into the inside of the wire feeding roller 6. The first insertion rod 311 is horizontally provided with two equal-height pins 312. The first insertion rod 311 is internally provided with a curved rod 313 which is hingedly arranged on the pins 312. The inside of the first insertion rod 311 is horizontally provided with a first reset spring 314 used for driving the curved rod 313 to reset.

[0028] The check mechanism 32 includes a ratchet wheel 321 which is fixedly connected with the mounting shaft at the bottom of the wire feeding device 3.

[0029] During the wire feeding process, when the wire feeding roller 6 is placed on the rotating table 31, the inner hole arranged in the inside of the wire feeding roller 6 is adapted to the outside of the first insertion rod 311. At this time, the end of the hingedly-arranged curved rod 313 in the inside of the first insertion rod 311 is extruded by the inner hole wall of the wire feeding roller 6, so as to drive the curved rod 313 to rotate along the axial direction of the pins 312. With the rotation of the curved rod 313, the top end of the curved rod 313 is gradually opened and tightly abuts against the inner hole wall of the wire feeding roller 6, so as to improve the stability of the connection between the rotating table 31 and the wire feeding roller 6. During the passive rotation of the wire feeding roller 6, the wire feeding roller 6 can effectively drive the rotating table 31 to synchronously rotate through the transmission of the first insertion rod 311. When the wire feeding roller 6 stops rotating, the rotating table 31 also stops rotating. At this time, the check mechanism 32 arranged at the bottom of the wire rack 1 quickly limits the rotating table 31, so as to effectively avoid the rotating table 31 from continuing to rotate due to the inertial effect.

[0030] As shown in the figure, Figure 1 , Figure 3 Figure 7 and Figure 8 As shown in the figure, the wire rack 1 is provided with a positioning mechanism 5 used for preventing the wire feeding roller 6 from tilting during the wire feeding. The positioning mechanism 5 includes an abutting head 53 which can be longitudinally moved and abut against the top of the wire feeding roller 6. The positioning mechanism 5 further includes a first hydraulic telescopic member 51 longitudinally arranged at the top of the wire rack 1 and used for driving the abutting head 53 to descend. The outside of the output end of the first hydraulic telescopic member 51 is provided with a limiting mechanism 54 used for limiting. The abutting head 53 is fixed to the bottom of the limiting mechanism 54.

[0031] When the output end of the first hydraulic telescopic component 51 extends outward, it drives the pressing head 53 downward until the pressing head 53 makes tight contact with the top of the feeding roller 6. This effectively prevents the feeding roller 6 from shifting due to the traction force of the wire during feeding. To further enhance the structural strength of the output end of the first hydraulic telescopic component 51, a limiting mechanism 54 is added to the outside of the output end. This effectively improves the load-bearing capacity of the output end of the first hydraulic telescopic component 51 and prevents the first hydraulic telescopic component 51 from bending and deforming due to excessive force.

[0032] See Figure 7 and Figure 8 As shown, the clamping head 53 includes a pressure sensor 531 fixed to the limiting mechanism 54 and electrically connected to the controller; the pressure sensor 531 is fixed to the lower end face of the moving base 541.

[0033] When the clamping head 53 contacts the top of the feeding roller 6, a pressure sensor 531 is installed to monitor the clamping force applied by the clamping head 53 in real time to ensure appropriate clamping force. This effectively prevents two situations: first, avoiding excessive downward pressure from the clamping head 53, which could damage or deform the surface of the feeding roller 6; second, avoiding excessive downward pressure from the clamping head 53, which could obstruct the rotation of the feeding roller 6 and affect the smoothness of the feeding process. Through the precise monitoring of the pressure sensor 531, it can be ensured that the clamping force of the clamping head 53 on the feeding roller 6 is always within a reasonable range.

[0034] See Figure 1 , Figure 7 and Figure 8 As shown, the clamping head 53 also includes a conical head 532, which is vertically mounted on the outside of the pressure sensor 531. When the feeding roller 6 is released, the conical head 532 rotates together with it.

[0035] The conical head 532 is rotatably mounted on the outside of the pressure sensor 531, allowing it to partially insert into the inner hole of the feed roller 6. When the feed roller 6 is passively rotated by the winding traction force, the conical head 532 is caused to rotate along the axial direction of the pressure sensor 531. This not only helps maintain the stability of the feed roller 6's rotation but also allows for fine-tuning of the axial position of the feed roller 6 through the engagement of the conical head 532 with the inner hole of the feed roller 6.

[0036] See Figure 4 and Figure 6 As shown, the check mechanism 32 also includes a pawl 322, which is hinged to the mounting post at the bottom of the wire feeder 1. One end of the pawl 322 can be adapted to the tooth groove of the ratchet 321.

[0037] The pawl 322 is hingedly provided with a pull spring 323 for resetting, and the end of the pull spring 323 away from the pawl 322 is hingedly connected to another mounting column arranged at the bottom of the base pay-off rack 1.

[0038] When the turntable 31 drives the ratchet wheel 321 to rotate, the pawl 322 is pushed by the teeth on the ratchet wheel 321. This causes the pawl 322 to rotate along the axis of the mounting column arranged on the pay-off rack 1, ensuring that the ratchet wheel 321 can rotate smoothly. At the same time, the tension of the pull spring 323 installed on the pawl 322 will gradually increase. When the turntable 31 stops driving the ratchet wheel 321, the ratchet wheel 321 no longer rotates, and the tension of the pull spring 323 will decrease accordingly until it disappears completely. At this time, the pull spring 323 will use its elastic potential energy to pull the pawl 322 to rotate in the opposite direction along the mounting shaft arranged on the pay-off rack 1. Until the end of the pawl 322 completely matches the tooth groove on the ratchet wheel 321, effectively preventing the turntable 31 from rotating outward.

[0039] Referring to Figure 8 As shown, a limiting hole 11 is arranged on the pay-off rack 1;

[0040] The limiting mechanism 54 includes a moving seat 541 fixed to the output end of the first hydraulic telescopic member 51, and a sliding rod 542 is arranged longitudinally on the moving seat 541 and can slide with the limiting hole 11.

[0041] By fixing the moving seat 541 to the output end of the first hydraulic telescopic member 51. When the output end of the first hydraulic telescopic member 51 extends downward, the first hydraulic telescopic member 51 simultaneously drives the moving seat 541 to move downward. In this process, the moving seat 541 further drives the sliding rod 542 to slide along the inside of the limiting hole 11. Effectively preventing unnecessary swinging of the output end of the first hydraulic telescopic member 51 in the working state, while also reducing the risk of bending of the first hydraulic telescopic member 51 due to the extension of the output end being blocked, thereby ensuring the stability and reliability of the entire system.

[0042] The utility model discloses a work, and the material feeding roller 6 is placed on the rotary table 31, and realizes adaptive installation through the first plug rod 311 and rotary table 31. When the inner hole in the material feeding roller 6 and the first plug rod 311 outside contact, the curved rod 313 is extruded and rotates along the pin 312 axial, and the curved rod 313 top gradually expands and tightly abuts on the inner hole wall of the material feeding roller 6, and the stability of the connection between the rotary table 31 and the material feeding roller 6 is enhanced. With the passive rotation of the material feeding roller 6, the rotary table 31 rotates synchronously through the transmission effect of the first plug rod 311. To ensure the stability of the material feeding roller 6 in the feeding process, the output end of the first hydraulic telescopic part 51 drives the downward movement of the abutting head 53, and until the abutting head 53 is in close contact with the top of the material feeding roller 6, effectively preventing the deviation. At the same time, the pressure sensor 531 real-time monitoring the pressing force of the abutting head 53 to the material feeding roller 6, ensures that the pressing force is always within a reasonable range, avoids the damage or rotation of the material feeding roller 6. In addition, the conical head 532 is rotatably installed outside the pressure sensor 531, and is partially inserted into the inner hole of the material feeding roller 6, and rotates along the pressure sensor 531 axial with the rotation of the material feeding roller 6, which helps to keep the stability of the rotation of the material feeding roller 6, and realizes the fine adjustment of the axial position of the material feeding roller 6. When the rotary table 31 drives the ratchet wheel 321 to rotate, the pawl 322 is rotated by the ratchet teeth, and the tension spring 323 bears the traction. When the rotary table 31 stops driving, the tension spring 323 pulls the pawl 322 to rotate reversely by using its elastic potential energy, until the one end of the pawl 322 is matched with the tooth groove of the ratchet wheel 321, effectively preventing the rotary table 31 from rotating back.

It should be pointed out that for ordinary skilled person in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model.
