[0023] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figure 1 、 Figure 2 and Figure 4, an embodiment provided by the present utility model: a wire feeding and positioning device for a multifunctional terminal machine, including a box body 1. A support frame 2 is fixedly connected to the right side of the top of the box body 1. Both sides of the top of the support frame 2 are fixedly connected with fixing blocks 5. A limiting groove 6 is opened inside the fixing block 5. A spring 7 is fixedly connected inside the limiting groove 6. The other end of the spring 7 is fixedly connected with a limiting block 8. One side of the limiting block 8 is fixedly connected with a pull rod 9. The other side of the limiting block 8 is fixedly connected with a clamping block 10. A support rod 11 is slidably connected inside the fixing block 5. A plurality of clamping grooves 12 are opened on the side of the support rod 11 close to the clamping block 10. A second wire feeding roller 13 is rotatably connected between the two clamping blocks 10. A motor 3 is installed outside the support frame 2. The output end of the motor 3 is connected with a first wire feeding roller 4 through a rotating shaft. The other end of the rotating shaft extends to the other side of the support frame 2 and is fixedly connected with a turntable 14. The limiting block 8 is slidably connected inside the limiting groove 6. The spring 7 is sleeved outside the pull rod 9. The longitudinal section of the clamping block 10 is square. The outside of the clamping block 10 is engaged with the inside of the clamping groove 12.

[0025] Specifically, the box body 1 plays a role in fixing the support frame 2, so that the support frame 2 can support and fix the fixing block 5. By pulling the pull rod 9 outside the fixing block 5, the pull rod 9 drives the limiting block 8 to move inside the limiting groove 6, thereby pressing the spring 7 to contract. The limiting groove 6 can limit the movement of the limiting block 8, making the structure operate stably. At the same time, the limiting block 8 will drive the clamping block 10 to disengage from the clamping groove 12. At this time, the support rod 11 can be moved, thereby changing the distance between the second wire feeding roller 13 and the first wire feeding roller 4, so as to adapt to wires of different thicknesses, improve the flexibility of the device, and will not produce deviation, improving the accuracy of wire feeding and ensuring the quality of product processing. Among them, the spring 7 can rebound after the pull rod 9 is released, thereby pushing the clamping block 10 to insert into the clamping groove 12 to complete the clamping, realizing the fixation of the support rod 11. The motor 3 is installed and fixed through the support frame 2, so that the motor 3 remains stable during operation, and then can drive the first wire feeding roller 4 to rotate under the connection of the rotating shaft, thereby realizing the operation of wire feeding.

[0026] Referring to Figure 3 and Figure 5 , a dust cleaning component is arranged on the top of the box body 1. The dust cleaning component is used for cleaning the dust on the surface of the wire. The dust cleaning component includes a sleeve 16. A piston 18 is slidably connected inside the sleeve 16. One side of the piston 18 is fixedly connected with a connecting rod 17. One end of the connecting rod 17 extends to the outside of the sleeve 16 and is rotatably connected with a moving rod 15. The other end of the moving rod 15 is rotatably connected to the outside of the turntable 14. A first one-way valve 19 is installed on the top of the sleeve 16. A second one-way valve 20 is installed on the side of the sleeve 16. An air delivery pipe 21 is fixedly connected to the outside of the second one-way valve 20. The other end of the air delivery pipe 21 is fixedly connected to the top of the fixing frame 22, and the end of the air delivery pipe 21 is fixedly connected with a spray head.

[0027] Specifically, the operation of the motor 3 causes the rotating shaft connected thereto to drive the turntable 14 to rotate, thereby driving the moving rod 15 to continuously move. Under the connection of the moving rod 15, the piston 18 reciprocates inside the sleeve 16, so that air enters the inside of the sleeve 16 from the first one-way valve 19 and then is discharged from the second one-way valve 20. Thus, it is discharged from the spray head connected to the other end through the delivery of the air delivery pipe 21. In this way, the dust on the surface of the wire can be blown off while feeding the wire, avoiding the influence of dust on the wire during the operation of the wire, improving the quality of the product. The fixing bracket 22 can fix the other end of the air delivery pipe 21, so that the spray head fixed at the end of the air delivery pipe 21 remains stable.

[0028] Refer to Figure 2 , a through hole 24 is opened on the left side of the top of the box body 1. A bearing plate 25 is rotatably connected inside the box body 1. A controller is arranged on the top of the box body 1. A plurality of universal wheels are installed at the bottom of the box body 1. A fixing bracket 22 is fixedly connected to the top of the box body 1. A guide roller 23 is rotatably connected inside the fixing bracket 22.

[0029] Specifically, the through hole 24 facilitates the wire to pass through the inside of the box body 1. The bearing plate 25 can place the wire to realize the support of the wire. The controller facilitates the control of the operation of the device, improving the degree of automation. The universal wheels can conveniently move the device, improving the flexibility of use. The guide roller 23 rotatably arranged inside the fixing bracket 22 can guide the movement of the wire, making the wire feeding more accurate.

[0030] Working principle: When using this device, first place the coiled wire on the bearing plate 25, pass one end of it through the through hole 24 and then above the guide roller 23, and then pass through between the first wire feeding roller 4 and the second wire feeding roller 13. At this time, by pulling the pull rod 9 on the outer sides of the two fixing blocks 5, the pull rod 9 drives the limiting block 8 to move inside the limiting groove 6, thereby pressing the spring 7 to contract, and at the same time driving the clamping block 10 to disengage from the clamping groove 12. At this time, the support rod 11 can be moved, thereby changing the distance between the second wire feeding roller 13 and the first wire feeding roller 4, so as to adapt to wires of different thicknesses, improving the flexibility of use of the device and not generating deviation, improving the accuracy of wire feeding, and at the same time making the surfaces of the first wire feeding roller 4 and the second wire feeding roller 13 close to the wire. Then, the operation of the motor 3 drives the first wire feeding roller 4 to rotate to realize the wire feeding operation of the wire. Secondly, when the motor 3 is running, it can drive the turntable 14 to rotate through the rotating shaft, and then the turntable 14 drives the moving rod 15 to move. Under the connection of the moving rod 15, the piston 18 reciprocates inside the sleeve 16, so that air can continuously enter, and is discharged from the spray head connected to the other end through the delivery of the air delivery pipe 21. In this way, the dust on the surface of the wire can be blown off while feeding the wire, avoiding the influence of dust on the wire during the operation of the wire, improving the quality of the product.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
