[0002] The copper wire drawing and unwinding machine is a key piece of equipment in the copper wire processing process. It is mainly used to unwind thick copper wire and guide it to the drawing machine for subsequent stretching. Existing expansion shaft unwinding machines only have the function of fixing the thick copper wire take-up roller. After the thick copper wire take-up roller undergoes axial sliding displacement on the expansion shaft, the expansion shaft unwinding machine does not have a real-time monitoring function, which affects the drawing quality, production efficiency and equipment stability of copper wire. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an expansion shaft pay-off machine that can perform real-time monitoring and generate an alarm signal after the coarse copper wire take-up roller generates axial sliding displacement on the expansion shaft.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: an expansion shaft wire feeding machine, comprising a rotary table body, a central shaft, a telescopic cylinder, an expansion shaft, an upper collar, a lower collar, an elastic cover, a touch switch, an alarm module, and a control module.

The piston rods of the telescopic cylinders are fixedly connected to the lower collar. Four expansion shafts are arranged in a ring array around the central shaft. The two ends of the first connecting rod are respectively hinged to the expansion shaft and the upper collar. The two ends of the second connecting rod are respectively hinged to the expansion shaft and the lower collar. The two ends of the third connecting rod are respectively hinged to the expansion shaft and the upper rotating body of the rotary table body.

[0005] The main body of the rotary table has symmetrical grooves on both sides of the top surface. The elastic cover is slidably installed in the groove. The guide sleeve is fixedly installed in the groove. The guide rod is slidably installed in the guide sleeve. The disc is fixedly installed on the top of the guide rod. The spring is sleeved on the guide rod. The upper and lower ends of the spring act on the disc and the guide sleeve respectively. The elastic cover is also screwed to the disc. The touch switch is fixedly installed in the groove. The elastic cover can contact the contact of the touch switch to make it actuate. The touch switch and the alarm module are respectively connected to the control module through circuits.

[0006] Preferably, a base is fixedly installed on the rotating body of the rotary table body, the central shaft is fixedly installed on the base, and the inner ends of the third connecting rod are hinged to the base.

[0007] Preferably, the guide rod is fixedly fitted with an anti-detachment stop ring.

[0008] Preferably, the main body of the rotary table is provided with a guide receiving groove in the radial direction that cooperates with the expansion shaft.

[0009] Preferably, the alarm module is mounted on a fixed base at the bottom of the rotary table body.

[0010] Compared with the prior art, the advantages of this utility model are: This expansion shaft wire feeding machine is in the open state by using an elastic cover pressure touch switch to monitor the axial displacement of the coarse copper wire take-up roller in real time, and sends an alarm signal through the alarm module to remind the operator to stop the machine in time and re-clamp and adjust the coarse copper wire take-up roller. This avoids the problem of axial relative displacement between the coarse copper wire take-up roller and the expansion shaft, which would affect the wire drawing quality, production efficiency and equipment stability.

[0015] The present invention will now be described in detail with reference to specific embodiments:

[0016] like Figures 1 to 3 The expansion shaft wire feeding machine shown includes a rotary table body 1, a central shaft 2, a telescopic cylinder 3, an expansion shaft 4, an upper collar 5, a lower collar 6, an elastic cover 8, a touch switch, an alarm module, and a control module. The bottom end of the central shaft 2 is fixedly installed on the upper rotating body of the rotary table body 1. The upper collar 5 is slidably installed on the rotary table body 1, and the lower collar 6 is slidably installed on the rotary table body 1. The cylinder bodies of the two telescopic cylinders 3 are symmetrically and fixedly installed on the rotary table body 1. The piston rod of the telescopic cylinder 3 is fixedly connected to the lower collar 6. The four expansion shafts 4 are arranged in a ring array around the central shaft 2. The two ends of the first connecting rod 41 are respectively hinged to the expansion shaft 4 and the upper collar 5. The two ends of the second connecting rod 42 are respectively hinged to the expansion shaft 4 and the lower collar 6. The two ends of the third connecting rod 43 are respectively hinged to the expansion shaft 4 and the upper rotating body of the rotary table body 1.

[0017] The main body of the rotating platform 1 has symmetrical grooves 13 on both sides of its top surface. The elastic cover 8 is slidably installed in the groove 13. The guide sleeve 93 is fixedly installed in the groove 13. The guide rod 92 is slidably installed in the guide sleeve 93. The top of the guide rod 92 is fixedly installed with a disc 91. A spring is sleeved on the guide rod 92. The upper and lower ends of the spring act on the disc 91 and the guide sleeve 93 respectively. The elastic cover 8 is also screwed to the disc 91. The touch switch is fixedly installed in the groove 13. The elastic cover 8 can contact the contact of the touch switch to make it actuate. The touch switch and the alarm module are respectively connected to the control module through circuits.

[0018] A base 7 is fixedly installed on the rotating body of the rotary table body 1, the central shaft 2 is fixedly installed on the base 7, and the inner ends of the third connecting rod 43 are hinged to the base 7.

[0019] The guide rod 92 is fixedly fitted with an anti-detachment stop ring. After the anti-detachment stop ring contacts the guide sleeve 93, it can prevent the bottom of the guide rod 92 from coming out of the guide sleeve 93.

[0020] The main body 1 of the rotary table is radially provided with a guide receiving groove 11 that cooperates with the expansion shaft 4. When the four expansion shafts 4 contract, they enter the guide receiving groove 11, which can reduce the axial dimension of the central shaft 2 and still meet the actual use requirements.

[0021] The alarm module is installed on a fixed base at the bottom of the rotary table body 1. The alarm module is set as a sound and / or light alarm module. When the two alarm modes are used simultaneously, the probability of the operator receiving the alarm signal can be further increased.

[0022] The piston rod of the telescopic cylinder 3 drives the lower collar 6 to move up and down along the central axis 2, realizing the expansion shaft 4 expansion / contraction. After the expansion shaft 4 expands, it fixes the thick copper wire take-up roller. The upper rotating body of the rotary table 1 rotates, driving the expansion shaft 4 and the thick copper wire take-up roller to rotate synchronously for wire feeding. At this time, the bottom end of the thick copper wire take-up roller presses against the elastic cover 8, causing the elastic cover 8 to overcome the spring force and move downward with the combination of the disc 91 and the guide rod 92. When the top surface of the elastic cover 8 is flush with the top surface of the upper rotating body of the rotary table 1, the bottom surface of the thick copper wire take-up roller simultaneously presses against the top surface of the elastic cover 8 and the top surface of the upper rotating body of the rotary table 1. The bottom surface of the elastic cover 8 presses against the contact of the touch switch, and the touch switch is in the closed state. When the coarse copper wire take-up roller undergoes axial displacement relative to the expansion shaft 4, the elastic cover 8 springs upward under the action of the spring force. The bottom surface of the elastic cover 8 releases the pressure on the contact of the touch switch. At this time, the touch switch is in the power-off state. The control module controls the alarm module to issue an alarm signal. After the operator stops the machine, the coarse copper wire take-up roller is re-clamped and adjusted.
