Therefore, a material discharging synchronizing device is needed to adjust the wire rod to keep near the center line transmission and discharging at any time. SUMMARY

[0003] Based on the content in the background art, the utility model discloses a material discharging synchronizing device, which comprises a material discharging frame, a walking wheel, a guide rail, a driving motor and a side detection device.

[0004] The material discharging frame is provided with a walking wheel, and the walking wheel is in contact with the guide rail. An annular groove is formed in the walking wheel, which is in contact with the guide rail to prevent the walking wheel from derailing when it is in operation. The material discharging frame can move left and right along the guide rail through the walking wheel.

[0005] The walking wheel is driven by the driving motor, which can change the moving direction of the material discharging frame along the guide rail by forward and reverse rotation. The driving motor is a speed reducer. When the driving motor rotates forward, the walking wheel can drive the material discharging frame to move right along the guide rail. When the driving motor rotates reversely, the walking wheel can drive the material discharging frame to move left along the guide rail.

[0006] A side detection device is arranged in front of the material discharging frame, which comprises a first moving roller, a second moving roller, a long plate, a first sliding block, a second sliding block, a first spring, a second spring, a first proximity sensor and a second proximity sensor.

[0007] The first moving roller and the second moving roller are both installed on the long plate, and are vertically and oppositely arranged. The first moving roller is located on the left side of the long plate, and the second moving roller is located on the right side of the long plate. The long plate is fixedly connected to the top end of the vertical column, and the vertical column is fixedly connected to the ground, so that the long plate is fixedly arranged. First long holes are formed in the long plate at the positions corresponding to the first moving roller, and second long holes are formed in the long plate at the positions corresponding to the second moving roller.

[0008] The shaft rod end of the first moving roller is clamped in the first long hole through a first sliding block, that is, the lower end of the shaft rod of the first moving roller is connected with a first sliding block, the front and rear sides of the first sliding block are provided with sliding grooves, and the first sliding block is clamped in the corresponding long hole through the sliding grooves, so that the first sliding block can slide along the first long hole, and the first moving roller can also move along the direction of the first long hole.

[0009] The shaft rod end of the second moving roller is clamped in the second long hole through a second sliding block, that is, the lower end of the shaft rod of the second moving roller is connected with a second sliding block, the front and rear sides of the second sliding block are provided with sliding grooves, and the second sliding block is clamped in the corresponding long hole through the sliding grooves, so that the second sliding block can slide along the second long hole, and the second moving roller can also move along the direction of the second long hole.

[0010] Of course, the first long hole and the second long hole are provided in the same direction as the direction of the guide rail, so that the first moving roller and the second moving roller can move left and right along the corresponding long hole. The specific structure of the first moving roller and the second moving roller is that the roller of the moving roller is sleeved on the shaft rod of the moving roller, and a bearing is arranged between the roller of the moving roller and the shaft rod of the moving roller, so that the roller of the moving roller can rotate along the axis.

[0011] The first long hole is also provided with a first spring, one end of the first spring is fixed to the left side of the first sliding block, and the other end of the first spring is fixedly connected to the inner wall of the first long hole.

[0015] The material shaft wound with the wire is unwound on the material rack, the transmitted wire is located between the first moving roller and the second moving roller, when the transmitted wire is greatly deviated to the left side, the wire compresses the first moving roller to cause the first spring to be compressed, the first moving roller moves to the left side, after the first proximity sensor detects that the distance between the first proximity sensor and the first moving roller is too small, the driving motor is driven to rotate in the positive direction, the walking wheel can drive the material rack to move right along the guide rail, so that the transmitted wire moves right to correct the deviation, and the first moving roller can also move right under the elastic recovery of the first spring.

[0016] When the wire material being transported is greatly deviated to the right side, the wire material presses the second moving roller, causing the second spring to compress, and the second moving roller moves to the right side. After the second proximity sensor detects that the distance between the second proximity sensor and the second moving roller is too small, the driving motor reverses, the walking wheels can drive the material feeding frame to move along the guide rail to the left, so that the wire material being transported moves to the left to correct the deviation, and the second moving roller can also move to the left under the elastic recovery of the second spring.

[0019] The information processing module compares and processes the detected distance information with the set distance information: after the distance detected by the first proximity sensor is less than the set distance, the driving motor is controlled to rotate forward, so that the material feeding frame can move along the guide rail in the direction that can increase the distance detected by the first proximity sensor, i.e. in the direction shown in the figure, so that the material feeding frame moves to the right;

[0020] After the distance detected by the second proximity sensor is less than the set distance, the driving motor is controlled to reverse, so that the material feeding frame can move along the guide rail in the direction that can increase the distance detected by the second proximity sensor, i.e. in the direction shown in the figure, so that the material feeding frame moves to the left;

[0021] After the distance detected by the first proximity sensor and the distance detected by the second proximity sensor are both greater than or equal to the set distance, the driving motor is controlled to stop working.

[0022] Under the above control principle, the material feeding synchronization device can automatically adjust at any time to keep the wire material being transported near the center line.
