[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0026] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0027] Combined with Figures 1-7 , a cutting device for enameled wire production of the present utility model includes a cutting table 1 and a material conveying table 2. A bracket 101 is fixedly arranged on the top of the cutting table 1. Two mounting frames 201 are symmetrically and fixedly arranged on the top of the material conveying table 2. A first shaft rod 301 is rotatably connected between the two mounting frames 201. A plurality of wire pay-off reels 3 are sleeved on the first shaft rod 301. A material conveying assembly 4 is arranged on one side close to the cutting table 1 between the two mounting frames 201. A cutting assembly 5 is arranged at the bottom of the bracket 101. Two pressing and fixing assemblies 6 are symmetrically arranged on the cutting assembly 5. A cutting opening 102 is opened at the middle position of the top surface of the cutting table 1. The material conveying assembly 4 includes two second shaft rods 401 rotatably connected to the mounting frames 201. A positioning plate 4011 is fixedly arranged on one side of the second shaft rod 401. A plurality of protrusions 4012 are circumferentially distributed on the second shaft rod 401. A plurality of pulleys 402 corresponding to the number and positions of the wire pay-off reels 3 are sleeved on the second shaft rod 401. A slot 4021 is opened at the center of the pulley 402. The slot 4021 is sleeved on the second shaft rod 401 and the protrusion 4012. A section of thread is arranged at the other end of the second shaft rod 401. A thread ring 403 is used to thread-connect with this end thread to fix the pulley 402.

[0028] Specifically, during installation, the pulley 402 is sleeved onto one end of the second shaft rod 401, and the slot 4021 is fitted with the bump 4012 so that the pulley 402 itself cannot rotate on the second shaft rod 401. When the pulley 402 moves to the positioning plate 4011, the next pulley 402 is sleeved. After all the pulleys 402 are sleeved, the threaded ring 403 is threadedly connected to the threaded end of the second shaft rod 401 to fix the pulley 402. Then, the second shaft rod 401 is rotatably connected between the mounting brackets 201. The enameled wire is drawn from the unwinding reel 3 to between the two pulleys 402. A motor is installed on the side of one of the mounting brackets 201 and is docked with the upper second shaft rod 401. At this time, the motor is started to drive the upper second shaft rod 401 to rotate, and the enameled wire moves accordingly, driving the lower second shaft rod 401 to jointly push the enameled wire towards the cutting table 1. When it moves to the cutting position 102, the cutting assembly 5 at the bottom of the bracket 101 presses down for cutting. This assembly is easy to operate, realizes automatic feeding of the enameled wire, has a high degree of automation, improves production efficiency, and can meet cutting of different lengths by adjusting the rotation speed to control the feeding speed.

[0029] Combined with Figure 4 , the cutting assembly 5 includes two electric push rods 501 fixed to the bottom of the cutting table 1. The bottom of the electric push rod 501 is connected to a mounting plate 502. In the middle of the bottom of the mounting plate 502, a cutting knife 503 is fixedly connected. When the enameled wire is transported to the cutting position 102 below the cutting assembly 5, the electric push rod 501 moves downward to drive the lower mounting plate 502 and the cutting knife 503 on the mounting plate 502 to move downward to complete the cutting of the enameled wire.

[0030] A clamping plate is provided at the top of the cutting knife 503. After the clamping plate is slid into the card slot of the mounting plate 502, bolts are used for fixation. The method of sliding the clamping plate at the top of the cutting knife 503 into the card slot of the mounting plate 502 and using bolts for fixation effectively ensures the cutting stability and is convenient for replacing the cutting knife 503. When replacement and maintenance are required, the device does not need to be disassembled, saving time and improving efficiency.

[0031] Combined with Figures 4-5, a pressing and fixing component 6 includes two limiting rods 602 slidably mounted on the mounting plate 502. A pressing plate 601 is fixed to the bottom of the limiting rod 602. A spring 603 is connected between the pressing plate 601 and the mounting plate 502. Multiple pressing blocks 6011 corresponding to the number and position of the wire pay-off reels 3 are fixed to the bottom of the pressing plate 601. The pressing blocks 6011 are designed in a semi-circular shape. When the electric push rod 501 pushes the mounting plate 502 downward, the bottom pressing plate 601 also moves downward accordingly. When the pressing blocks 6011 contact the top surface of the cutting table 1, the enameled wire is pressed and fixed. At this time, the spring 603 is compressed, and the limiting rods 602 slide in the mounting plate 502. The mounting plate 502 continues to move downward to complete the cutting, and the pressing and fixing are completed during the cutting process, preventing the enameled wire from warping due to the force generated during cutting and affecting the cutting effect, greatly improving the cutting accuracy and quality.

[0032] A layer of rubber pad 6012 is fixed to the surface of the pressing block 6011. By fixing the rubber pad 6012 on the surface of the pressing block 6011, buffering is provided during pressing and fixing to prevent damage to the enameled wire. Good elasticity and anti-slip properties can more stably press and fix the enameled wire, and at the same time reduce component friction and extend the service life of the device.

[0033] Combined Figures 1-4 , an anti-slip coating made of a rubber material is coated on the surface of the pulley 402. By coating the surface of the pulley 402 with a rubber material anti-slip coating, the friction between the pulley 402 and the enameled wire can be significantly improved, making the transportation of the enameled wire more stable, thus improving the transportation efficiency. Moreover, the rubber material is wear-resistant and corrosion-resistant, which can well extend the service life of the pulley 402.

[0034] Multiple wire grooves 103 corresponding to the number and position of the wire pay-off reels 3 are opened on both sides of the cutting opening 102 at the top of the cutting table 1. The wire grooves 103 are located directly below the pressing blocks 6011 and correspond to them. The wire grooves 103 are designed in an inwardly concave semi-circular shape. By opening the inwardly concave semi-circular wire grooves 103 corresponding to the pressing blocks 6011 on both sides of the cutting opening 102 at the top of the cutting table 1, it is convenient to cooperate with the pressing blocks 6011 to press and fix the enameled wire when the pressing blocks 6011 press down. And it corresponds to the number and position of the wire pay-off reels 3, which can well separate the enameled wires, and multi-station cutting will not be disordered, improving the production efficiency.

[0035] Two clamping blocks 104 are fixed to one side of the cutting table 1. An aggregate box 7 is placed between the clamping blocks 104. A brakeable universal wheel is fixed to the bottom of the aggregate box 7. When the enameled wire is cut, the material conveying component 4 continues to feed, pushing the cut enameled wire out of the cutting table 1 and falling into the aggregate box 7 in front, completing automatic aggregation. After the aggregation is completed, the brake is released and the aggregate box 7 can be moved away. This process is convenient to operate and saves manpower, while the clamping blocks 104 limit the position of the aggregate box 7, improving the accuracy of the aggregation position.
