Description

Technical Field

[0001] The invention belongs to the field of metal casting and smelting equipment, and in particular relates to an anti-slip device for an intelligent wire feeding machine. Background Art

[0002] The wire feeder is used in the foundry and smelting industry to add cored wire made of alloy core wire to molten iron to achieve the purpose of spheroidization, creeping, deoxidation, desulfurization, change the morphology of inclusions, improve material properties, fine-tune the composition, save alloy and reduce material costs. The wire feeder works by driving the driven friction wheel through the cylinder to press down the cored wire and clamp the cored wire between the active friction wheel and the driven friction wheel. Then the active friction wheel rotates to drive the clamped cored wire to be shot into the molten iron, and the driven friction wheel will also rotate when the active friction wheel drives the cored wire to move.

[0003] At present, due to the production process and actual production conditions of the cored wire and the steel strip, the core material of the cored wire may be uneven or loose. This will cause the two friction wheels to fail to clamp the cored wire during the wire feeding process of the wire feeder, resulting in slippage between the active friction wheel and the cored wire, the driven friction wheel also stops rotating, and the cored wire will stop adding to the molten iron. At this time, manual intervention is required to clamp the cored wire by the two friction wheels again and implement the wire feeding work, which can easily cause the entire package of molten iron to be scrapped and returned to the furnace for re-heating, and will also reduce work efficiency. Summary of the invention

[0004] The object of the present invention is to provide an anti-slip device for an intelligent wire feeding machine to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above purpose, the specific technical solution of an intelligent wire feeding machine anti-slip device of the present invention is as follows:

[0006] It includes a shell, a meter and a PLC. The shell is provided with a power unit, and a transmission shaft is distributed on the power unit. An active friction wheel is provided at one end of each transmission shaft away from the power unit. An opening is provided on one side of the shell, and an outlet is provided on the other side. The cored wire enters from the opening and passes over the active friction wheel and then is led out through the outlet. A pressing part is provided at a position corresponding to each active friction wheel on the shell. The pressing part can be lowered to clamp the cored wire between the active friction wheel and the pressing part. A meter for measuring the length of the cored wire is provided on the pressing part. The power unit, the meter and the pressing part are all electrically connected to the PLC.

[0007] The intelligent anti-slip device for wire feeding machine of the present invention has the following advantages:

[0008] 1. The present invention sets a second cylinder on the top plate of the frame, and connects the second cylinder to one of the lower pressure parts. When the core material of the cored wire is uneven or insufficient, and the active friction wheel and the driven friction wheel cannot clamp the cored wire, the PLC detects that the meter counter stops counting, and the PLC sends a signal to the second cylinder. The second cylinder drives the lower pressure part connected to it to compact the cored wire, thereby playing an anti-skid role between the active friction wheel and the cored wire. The rotation of the active friction wheel will drive the cored wire to make a linear motion again, so that the cored wire resumes the wire feeding work. When the meter counter starts counting again, the PLC sends a signal to the second cylinder to make the lower pressure part driven by it rise and return to the initial position. This can save time wasted on manual intervention to make the anti-skid device of the wire feeder resume the wire feeding work of the cored wire, thereby improving the working efficiency of the anti-skid device of the wire feeder. At the same time,

[0009] 2. The present invention drives the driven friction wheel on the pressing part to descend by the second cylinder, and the driven friction wheel rotates under the drive of the pneumatic motor, and gives the cored wire a power in another direction to make the cored wire move linearly, so that the driven friction wheel and the cored wire have a non-slip effect, thereby avoiding the loss and waste caused by the scrapping of molten iron and the re-reheating caused by the wire jamming or slipping when the wire feeder is working.

[0010] 3. The present invention arranges a pneumatic motor on the sliding component, and the pneumatic motor is connected to the pressing part arranged on the second cylinder. The PLC sends signals to the second cylinder and the pneumatic motor at the same time. When the second cylinder drives the pressing part connected to it to move downward, the pneumatic motor moves downward synchronously with the pressing part and drives the driven friction wheel on the pressing part to rotate. The driven friction wheel and the corresponding active friction wheel re-clamp the cored wire, and the thrust of the driven friction wheel can be increased in addition to the thrust of the active friction wheel, so that the cored wire can resume the feeding work more smoothly and gently, thereby improving the practicability of the anti-slip device of the wire feeding machine.

[0011] 4. The present invention can guide the cored wire entering into the anti-slip device of the wire feeder by providing a guide portion, so as to prevent the cored wire from escaping from between the active friction wheel and the driven friction wheel, thereby affecting the normal operation of the anti-slip device of the wire feeder.

[0019] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0021] Please refer to the attached Figures 1 to 5 An anti-slip device for an intelligent wire feeding machine according to some embodiments of the present invention is described. Figure 1 The direction indicated by the arrow is the front of the anti-slip device of the wire feeder, and the opposite direction is the rear of the anti-slip device of the wire feeder.

[0022] like Figures 1 to 5As shown, an intelligent anti-slip device for a wire feeding machine of the present invention comprises a housing, a meter 18 for measuring the length of a cored wire 9, and a PLC. A power unit is provided on the housing, and a transmission shaft 6 is distributed on the power unit and extends outward. An active friction wheel 7 is provided at the extended end of each transmission shaft 6, and the power unit drives the active friction wheel 7 to rotate through the transmission shaft 6. An opening is provided on the front side of the housing, and an outlet is provided on the rear side. The cored wire 9 enters from the opening and passes over the active friction wheel 7 and then is led out through the outlet. The cored wire 9 extending into the frame 2 is located on each active friction wheel 7. A pressing portion 8 is provided at a position corresponding to each active friction wheel 7 on the housing. The cored wire 9 in the frame 2 is located below the pressing portion 8, and the pressing portion 8 can move up and down on the housing, and the pressing portion 8 descends to clamp the cored wire 9 between the active friction wheel 7 and the pressing portion 8, and then the power unit drives the active friction wheel 7 to make the cored wire 9 clamped between the active friction wheel 7 and the pressing portion 8 move linearly. When the cored wire 9 performs a linear motion, a meter 18 for measuring the feeding length of the cored wire 9 is provided on one side of the pressing portion 8 .

[0023] The power unit, the meter counter 18 and the pressing unit 8 are all electrically connected to the PLC so that the PLC can control and monitor the power unit, the meter counter and the pressing unit 8 .

[0024] Specifically, the shell is composed of a base plate 1 and a frame 2 arranged on one side of the base plate 1. A power device consisting of a motor 3, a reducer 4 and a gear box 5 is arranged on the base plate 1, and the motor 3 and the gear box 5 are connected through the reducer 4. The transmission shaft 6 is rotatably distributed on the gear box 5. There are three transmission shafts 6. Under the action of the gear box 5, each transmission shaft 6 can rotate synchronously. Each transmission shaft 6 passes through the frame 2 and extends to the inside of the frame 2. Each transmission shaft 6 is rotatably arranged with the frame 2. An active friction wheel 7 is arranged at the extended end of each transmission shaft 6. Each active friction wheel 7 is located in the frame, and the axis of each active friction wheel 7 is arranged in parallel. Specifically, the pressing part 8 is arranged on the bottom surface of the top plate of the frame 2. The motor 3 is electrically connected to the PLC, and the PLC can control the start and stop of the motor 3.

[0025] like Figure 5As shown, the first gear 15 and the second gear 16 are arranged at intervals in the gear box 5, and the first gear 15 and the second gear 16 are both arranged to rotate with the gear box 5, and each second gear 16 is located between the adjacent first gears 15 and meshes. The arrangement of the second gear 16 can make the rotation direction of each first gear 15 the same, that is, the rotation direction of each active friction wheel 7 connected to each first gear 15 through the transmission shaft 6 is the same, each first gear 15 is provided with a transmission shaft 6, and the output end of the reducer 4 is connected to any first gear 15. Specifically, there are three first gears 15, and the rotation of the three first gears 15 can drive the active friction wheels 7 on each transmission shaft 6 to rotate, and the cored wire 9 clamped between the active friction wheel 7 and the pressing part 8 can be transported. The reducer 4 connected between the motor 3 and the gear box 5 can increase the torque of the motor 3 on the gear box 5, so that the gears in the gear box 5 rotate more smoothly.

[0026] It should be noted that the sensor of the meter counter 18 is connected to the PLC of the anti-slip device of the wire feeder, and the PLC can monitor the meter counter 18. When the anti-slip device of the wire feeder is feeding the cored wire 9, the meter counter 18 can measure the feeding length of the cored wire 9 in real time, so that the human can know the feeding length of the anti-slip device of the wire feeder in real time.

[0027] like Figure 1 As shown, the pressing part 8 is provided with three groups corresponding to the active friction wheel 7, and each pressing part 8 includes a first cylinder 801 provided on the inner wall of the top plate of the frame 2, and the first cylinder 801 is provided with a telescopic end facing downward, and the PLC is electrically connected to the first cylinder 801. A clamping frame 802 is provided at the telescopic end of the first cylinder 801, and a driven friction wheel 803 is rotatably provided in the clamping frame 802. The meter counter 18 is provided on the clamping frame 802 and connected to the driven friction wheel 803, and the driven friction wheel 803 rotates to drive the meter counter 18 to perform meter counting. The outer walls of the driven friction wheel 803 and the active friction wheel 7 are provided with teeth, and when the corresponding active friction wheel 7 and the driven friction wheel 803 clamp the cored wire 9, the teeth on the active friction wheel 7 and the driven friction wheel 803 can press tooth marks on the cored wire 9 to improve the transmission effect of the active friction wheel 7 and the driven friction wheel 803 on the cored wire 9. Of course, the active friction wheel 7 and the driven friction wheel 803 may also be provided with a smooth surface or a groove adapted to the cored wire 9 may be provided on the circumferential outer surface of each friction wheel, and no excessive restrictions are made here.

[0028] When the anti-slip device of the wire feeding machine needs to feed the cored wire 9, firstly, air is ventilated to each first cylinder 801 arranged on the inner plate of the frame 2 through an air pump, and the first cylinder 801 drives the corresponding driven friction wheel 803 to move downward through the clamping frame 802, and makes the lowest end of the driven friction wheel 803 and the top end of the corresponding active friction wheel 7 clamp the cored wire 9, and the motor 3 provides power to each first gear 15 and the second gear 16 inside the gear box 5 through the reducer 4, and each active friction wheel 7 rotates through the transmission shaft 6 of the first gear 15 corresponding to it on the gear box 5, and the cored wire 9 is driven by the active friction wheel 7 to move, and then the driven friction wheel 803 also starts to rotate under the action of the cored wire 9, and the meter 18 starts to work.

[0029] Preferably, a second cylinder 11 is provided on the top plate of the frame 2, and the telescopic end of the second cylinder 11 penetrates the frame 2 and is connected to the first cylinder 801 of the pressing part 8. Specifically, when the cored wire 9 cannot be clamped by the active friction wheel 7 and the driven friction wheel 803 due to uneven or insufficient core material, the active friction wheel 7 and the cored wire 9 slip, the driven friction wheel 803 stops rotating, and the meter counter 18 stops counting. When the PLC detects that the meter counter 18 stops working, the PLC sends a signal to the second cylinder 11, and the second cylinder 11 drives the pressing part 8 connected to it to move to the The active friction wheel 7 in the middle of the frame 2 rotates and continues to drive the cored wire 9 to make a linear motion, so that the cored wire 9 resumes the wire feeding work. The driven friction wheel 803 also resumes its rotation at this time, and the meter counter 18 continues to count meters. When the PLC detects that the meter counter 18 re-detects the meter, the PLC sends a signal to the second cylinder 11 to make the downward pressure part 8 driven by it rise and return to the initial position. Each active friction wheel 7 in the frame 2 and the driven friction wheel 803 corresponding to the downward pressure part 8 continue to clamp the cored wire 9 and implement the wire feeding work. This prevents the active friction wheel 7 from slipping with the cored wire 9, and also saves the time wasted by manual intervention to resume the wire feeding work, thereby improving the working efficiency of the anti-slip device of the wire feeding machine.

[0030] like Figure 1 and Figure 4As shown, the frame 2 is symmetrically provided with a limit assembly 10, and the limit assembly 10 includes a first limit block 1001 and a second limit block 1002. A slide groove is provided on one side of the first limit block 1001, and a slide groove is provided on both sides of the left and right sides of the second limit block 1002. The clamping frame 802 of the first pressing part 8 on both sides of the frame 2 is slidably arranged between the first limit block 1001 and the second limit block 1002, and the clamping frame 802 of each pressing part 8 in the middle of the frame 2 is slidably arranged between the adjacent second limit blocks 1002. The arrangement of the first limit block 1001 and the second limit block 1002 can increase the stability of each pressing part 8 arranged corresponding thereto, and at the same time, it is also convenient for the driven friction wheel 803 on the clamping frame 802 to be positioned with the corresponding active friction wheel 7, so as to prevent the problem of positional displacement between the corresponding driven friction wheel 803 and the active friction wheel 7 after each first cylinder 801 is used for a long time.

[0031] As another preferred embodiment, Figure 2 , Figure 4 and Figure 5 As shown, a through slot 17 is provided on the frame 2, a sliding component 12 is provided on the side of the frame 2 opposite to the pressing part 8, an air motor 14 is provided on the sliding component 12, the output end of the air motor 14 passes through the through slot 17 and is connected to the driven friction wheel 803 of the pressing part 8, and the air motor 14 is electrically connected to the PLC. The through slot 17 on the frame 2 is a longitudinal long slot, and the width of the through slot 17 is wider than the diameter of the output end of the air motor 14, so that the output end of the air motor 14 can move up and down in the through slot 17.

[0032] The sliding member 12 includes a longitudinal sliding bar 1202 symmetrically arranged on the left outer wall of the frame 2, and the upper end of the sliding bar 1202 is detachably connected to the frame 2 through a clamp 1201, and the clamp 1201 and the frame 2 can be installed by bolts. A sliding plate 1203 is slidably arranged on the two sliding bars 1202, and the pneumatic motor 14 is arranged on the sliding plate 1203. The pneumatic motor 14 can move up and down between the two sliding bars 1202 through the sliding plate 1203. Specifically, when the second cylinder 11 drives the connected pressing part 8 to move downward, the pneumatic motor 14 connected to the pressing part 8 will move downward from the sliding rod 1202 through the sliding plate 1203. At the same time, when the second cylinder 11 receives the PLC signal and starts to move downward, the PLC will also send a signal to the pneumatic motor 14 to ventilate the pneumatic motor 14 and drive the connected driven friction wheel 803 to rotate synchronously. The driven friction wheel 803 connected to the pneumatic motor 14 has the same rotation direction and speed as the active friction wheel 7. The rotating driven friction wheel 803 and the active friction wheel 7 simultaneously clamp and apply force to the cored wire 9 due to uneven and insufficient core material, so as to quickly restore the cored wire 9 to the wire feeding work.

[0033] In this embodiment, the second cylinder 11 and the pneumatic motor 14 are preferably one, and the second cylinder 11 and the pneumatic motor 14 are correspondingly arranged, and are simultaneously connected to the driven friction wheel 803 in any pressing part 8. Specifically, in this embodiment, the second cylinder 11 is connected to the driven friction wheel 803 of the pressing part 8 in the middle of the frame 2, and the pneumatic motor 14 is connected to the driven friction wheel 803.

[0034] As a further improvement, a guide portion 13 is provided at the opening of the frame 2, and the guide portion 13 can limit and guide the cored wire 9 to prevent the cored wire 9 from rubbing against the opening for a long time, which will increase the size of the opening and damage the appearance of the cored wire 9. The guide portion 13 includes a guide frame 1301 provided at the opening, and a first rotating wheel 1302 and a second rotating wheel 1303 are symmetrically rotated in the guide frame 1301, and the axes of the first rotating wheel 1302 and the second rotating wheel 1303 are staggered and vertically arranged, and the second rotating wheel 1303 is located on one side of the first rotating wheel 1302. Specifically, there are two first rotating wheels 1302 and two second rotating wheels 1303 respectively, and a rectangular wire straightener is combined and formed in the middle of the two first rotating wheels 1302 and the two second rotating wheels 1303. The cored wire 9 can pass through the rectangular wire straightener. The cored wire 9 passing through the rectangular wire straightener passes between each active friction wheel 7 and each driven friction wheel 803 and then passes out through the outlet. When the active friction wheel 7 and the driven friction wheel 803 start to feed the clamped cored wire 9, the cored wire 9 will have a large deviation in the rectangular wire straightener, that is, the cored wire 9 contacts the first rotating wheel 1302 or the second rotating wheel 1303. At this time, the first rotating wheel and the second rotating wheel 1303 will limit the cored wire 9 to prevent the cored wire 9 from escaping from the rectangular wire straightener and between the active friction wheel 7 and the driven friction wheel 803. At the same time, in order to reduce the friction when the cored wire 9 contacts the first rotating wheel 1302 and the second rotating wheel 1303, when the cored wire 9 contacts the first rotating wheel 1302 and the second rotating wheel 1303, the first rotating wheel 1302 and the second rotating wheel 1303 will rotate with the cored wire 9, reducing the friction of the first rotating wheel 1302 and the second rotating wheel on the cored wire 9, preventing the cored wire 9 from being damaged, and playing a protective effect on the cored wire 9. In order to prevent the cored wire 9 between the active friction wheel 7 and the driven friction wheel 803 from escaping, an auxiliary wire tube 19 is provided inside the frame 2, and there are two auxiliary wire tubes 19, and the cored wire 9 can pass through the auxiliary wire tubes 19.

[0035] Method of use: insert the cored wire 9 from the opening of the frame 2 and extend it through the outlet, start each first cylinder 801, each first cylinder 801 drives the driven friction wheel 803 connected to it through the clamping frame 802 to descend, and clamp the cored wire 9 between the corresponding active friction wheel 7 and the driven friction wheel 803. Start the motor 3, the motor 3 drives the transmission shaft 6 connected to each first gear 15 in the gear box 5 to rotate synchronously through the reducer 4, at this time, each active friction wheel 7 rotates synchronously, the cored wire 9 clamped between each active friction wheel 7 and each driven friction wheel 803 is fed, the driven friction wheel 803 also starts to rotate under the transmission of the cored wire 9, and the meter 18 used to measure the cored wire 9 also starts to work. When the cored wire 9 has insufficient or uneven core material locally, the diameter of the cored wire 9 changes, the corresponding active friction wheel 7 and the driven friction wheel 803 cannot hold the cored wire 9, the active friction wheel 7 and the cored wire 9 slip, the driven friction wheel 803 stops rotating, and the meter counter 18 stops working. When the PLC detects that the meter counter 18 stops working, it sends a signal to the second cylinder 11 and the pneumatic motor 14. At this time, the second cylinder 11 and the pneumatic motor 14 work at the same time, and the driven friction wheel 803 connected to the pressing part 8 of the second cylinder 11 rotates with the starting motor, and the second cylinder 11 drives the driven friction wheel 803 connected to it to rotate. The pressing part 8 connected to the second cylinder 11 moves downward, so that the driven friction wheel 803 rotating in the pressing part 8 connected to the second cylinder 11 and the corresponding active friction wheel 7 clamp the cored wire 9 again, and the active friction wheel 7 and the driven friction wheel 803 that clamp the cored wire 9 apply force at the same time, which can quickly restore the wire feeding work of the cored wire 9. When the PLC detects that the meter counter 18 resumes counting again, it sends a signal to the second cylinder 11 and the pneumatic motor 14 again, and the second cylinder 11 drives the pressing part 8 connected to it to rise to the initial position, and the pneumatic motor 14 drives the driven friction wheel 803 connected to it to stop rotating.
