Description

Technical Field

[0001] This invention relates to the technical field of steel wire cord processing, and in particular to a steel wire cord uninterrupted feeding machine. Background Technology

[0002] In the tire manufacturing industry, especially in the production of high-performance radial tires, steel cord serves as a key reinforcing skeleton material. Its performance directly determines the tire's load-bearing capacity, durability, high-speed stability, and safety. Steel cord has extremely high tensile strength, fatigue resistance, and dimensional stability. It is a core component that withstands complex stresses (such as rolling pressure, centrifugal force, and impact loads) during tire operation. Therefore, the stability, efficiency, and continuity of the steel cord laying process are important foundations for ensuring the quality of subsequent calendering, cutting, and other processes, as well as overall production efficiency.

[0003] Traditional steel cord feeding methods typically use single-station feeding machines. When the cord on a reel is used up, the entire production line must be stopped, and operators must manually replace it with a new full reel. The ends of the new cord must then be re-threaded and connected to subsequent equipment before production can be restarted. This process leads to frequent production interruptions, long downtime, and low production efficiency. In addition, repeated stopping, starting, and manual threading operations can easily cause fluctuations in cord tension and positional deviations. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a non-stop wire cord feeding machine, the specific technical solution of which is as follows: The present invention provides a continuous wire cord feeding machine, comprising a switching structure for switching wire cord storage reels, a clamping structure for conveying wire ends on the reels, a feeding structure for continuous feeding, and an auxiliary structure for connecting wire ends on one reel to wire cord on another reel. The transposition structure includes a long plate and a power shaft located in the middle of the long plate for driving the long plate to rotate. Rotating rollers for mounting spools are provided at both ends of the long plate. The wire feeding structure includes two wire feeding reels arranged vertically.

[0005] Furthermore, a circular groove is provided in the middle area of ​​the outer circumference of the wire feeding reel, and synchronous teeth are provided on both sides of the circular groove. The two wire feeding reels are driven by meshing with each other through the synchronous teeth. The area of ​​the synchronous teeth near the circular groove is provided with a slope surface that cooperates with the circular groove.

[0006] Furthermore, the auxiliary structure includes a conductive layer disposed on the circular groove.

[0007] Furthermore, the wire feeding structure also includes a support shaft disposed on each of the wire feeding wheels and two side beams disposed opposite to each other. The support shaft on one of the wire feeding wheels is rotatably disposed on the side beam, and the support shaft on the other wire feeding wheel is slidably disposed on the side beam through a movable sleeve, and the movable sleeve and the side beam are connected by a spring piece.

[0008] Furthermore, the auxiliary structure also includes a support plate and a conductive ring disposed on the movable sleeve, and the conductive ring is fitted on the corresponding support shaft, and the conductive ring is electrically connected to the conductive layer on the corresponding pay-off reel; Two auxiliary wheels are rotatably mounted on the support plate. The two auxiliary wheels are driven by a conductive belt. When the movable sleeve moves, the conductive ring contacts the conductive belt and is electrically connected to it.

[0009] Furthermore, the conductive strip is composed of a conductive layer, a rubber layer located outside the conductive layer, and a plurality of conductive sheets disposed on the rubber layer, wherein the conductive sheets are electrically connected to the conductive layer, and the plurality of conductive sheets are equidistantly distributed on the rubber layer.

[0010] Furthermore, the support plate is vertically slidably mounted on the side beam; The wire feeding structure also includes a synchronous wheel rotatably mounted on the side beam, and two synchronous rods rotatably mounted on the synchronous wheel, and the two synchronous rods are respectively rotatably connected to the movable sleeve and the support plate on the side beam; The axis of rotation of the synchronous wheel is located between the movable sleeve and the support plate.

[0011] Furthermore, a first baffle and a second baffle are slidably disposed on the rotating roller. The first baffle is connected to the long plate by a spring. The second baffle is provided with a plurality of insert rods. A plurality of slots are provided at the end of the rotating roller. The slots are used in conjunction with the insert rods.

[0012] The beneficial effects of this invention are as follows: By connecting the wire ends on the spool fully loaded with steel wire cord to the steel wire cord on the spool in the unloading state, the steel wire cord can be continuously released, improving the continuity of the unloading operation, avoiding frequent downtime that leads to low production efficiency, and its operation is simple and can significantly save manpower; by using the repositioning structure to repeatedly transfer new spools to the unloading position, the unloading operation and spool assembly operation can be carried out in separate areas and simultaneously, avoiding downtime waiting.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0018] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0019] like Figures 1 to 5 As shown, the present invention provides a continuous wire cord feeding machine, which includes a switching structure for switching wire cord storage reels, a clamping structure 1 for conveying the wire ends on the reels, a feeding structure 2 for continuous feeding, and an auxiliary structure for connecting the wire ends on one reel to the wire cord on another reel. The transposition structure includes a long plate 4 and a power shaft 3 located in the middle of the long plate 4 for driving the long plate 4 to rotate. Rotary rollers 5 for mounting spools are provided at both ends of the long plate 4. The line feeding structure 2 includes two line feeding reels 6 distributed vertically.

[0020] In this invention, the transposition structure and the wire feeding structure 2 can be distributed left and right. The clamping structure 1 is set above the transposition structure and will not interfere with the operation of the transposition structure. The power shaft 3 can be powered by a motor, thereby causing the long plate 4 to rotate and the two rotating rollers 5 at both ends of the long plate 4 to switch positions. The rotation of the long plate 4 can be on a horizontal or vertical plane, as long as the position switching function of the two rotating rollers 5 can be completed. In order to facilitate operation and set up more workstations, the rotating rollers 5 can also be set up in multiple positions around the axis of the power shaft 3. In this way, the position of each rotating roller 5 is a workstation. Based on multiple workstations, a number of tasks such as wire feeding, wire reel disassembly, and wire reel assembly can be set up.

[0021] One of the rotating rollers 5 on the long plate 4 is close to the feeding structure 2. When the remaining amount of steel wire cord on the rotating roller 5 is small, the clamping structure 1 conveys the end of the steel wire cord on the other rotating roller 5 toward the feeding structure 2 and feeds the end of the cord into the space between the two feeding wheels 6 inside the feeding structure 2. At this time, the end of the cord overlaps with the cord between the two feeding wheels 6 and is connected by an auxiliary structure. In this way, the cord in the continuous feeding state will pull the reels on the two rotating rollers 5 to move synchronously and continuously feed the cord until the reel on the rotating roller 5 close to the feeding structure 2 completely releases the cord. Then, the drive shaft 3 rotates, causing the two rotating rollers 5 to switch positions. The reel carrying a large amount of cord and the corresponding rotating roller 5 move to a position close to the feeding structure 2, thereby realizing the uninterrupted feeding of the cord. The rotating roller 5 that has finished feeding moves to the side away from the feeding structure 2, the reel on the rotating roller 5 is removed, and a new reel is installed on the rotating roller 5.

[0022] It should be noted that the two feed rollers 6 clamp and feed the cord between them. Here, a motor can be installed on the feed rollers 6 to enable the feed rollers 6 to rotate actively and feed the cord, or the cord can be continuously released by pulling the cord using external equipment. In this case, the feed rollers 6 only need to clamp the cord.

[0023] The clamping structure 1 can use a robotic arm to transport the wire end, or it can use a method such as... Figure 1 As shown, the clamping structure 1 includes two horizontally arranged transmission wheels 27, a transmission belt 28 mounted on the two transmission wheels 27, a slider 29 that can move laterally and is connected to the transmission belt 28, and two rubber pillars 30 rotatably mounted on the slider 29. The vertical connection line of the two rubber pillars 30 is inclined, allowing the thread end to be placed directly between the two rubber pillars 30. The two rubber pillars 30 clamp the thread end, and then the transmission wheels 27 and the transmission belt 28 move, pulling the slider 29 and the thread end on it to move, thus conveying the thread end into the pay-off structure 2. The inclined vertical connection line of the two rubber pillars 30 makes it easier for the thread end to face between the two pay-off wheels 6, thereby facilitating the clamping and conveying of the thread end by the rotating pay-off wheels 6. Of course, in order to facilitate the separation of the rubber pillars 30 from the cord, the rubber pillars 30 can be made into a cone shape, or a propulsion structure such as a cylinder can be provided on the slider 29 to control the movement of the rubber pillars 30 along their own axis, so as to facilitate the adjustment of the position of the rubber pillars 30.

[0024] By connecting the wire ends on the spool fully loaded with steel wire cord to the steel wire cord on the spool in the unloading state, the steel wire cord can be continuously released, improving the continuity of the unloading operation, avoiding frequent downtime that leads to low production efficiency, and its operation is simple and can significantly save manpower; by using the repositioning structure to repeatedly transfer new spools to the unloading position, the unloading operation and spool assembly operation can be carried out in separate areas and simultaneously, avoiding downtime waiting.

[0025] Furthermore, a circular groove 7 is provided in the middle area of ​​the outer circumference of the wire feeding reel 6, and synchronous teeth 8 are provided on both sides of the circular groove 7. The two wire feeding reels 6 are driven by meshing with each other through the synchronous teeth 8. The area of ​​the synchronous teeth 8 near the circular groove 7 is provided with a slope 9 that cooperates with the circular groove 7.

[0026] The circular groove 7 between the two feed rollers 6 can form a closed ring. This shape can confine the cord within it, thereby preventing the cord from moving randomly between the two feed rollers 6 and improving the stability of cord conveying. The synchronous teeth 8 on the two feed rollers 6 can ensure that the two feed rollers 6 can move synchronously. The slope 9 can be used in conjunction with the circular groove 7 to push the cord that deviates from the middle of the feed rollers 6 toward the inside of the circular groove 7.

[0027] Furthermore, the auxiliary structure includes a conductive layer disposed on the circular groove 7.

[0028] When the end of the wire on a spool moves between the two feed rollers 6, the two feed rollers 6 in motion can clamp and feed the end of the wire. At this time, the wire end and the cord between the two feed rollers 6 are simultaneously fed, which energizes the conductive layers on the two circular grooves 7. At this time, the closest position of the two conductive layers performs discharge welding on the end of the wire and the cord between them, thereby connecting them together.

[0029] Furthermore, the wire feeding structure 2 also includes a support shaft 10 disposed on each wire feeding wheel 6 and two opposing side beams 11. The support shaft 10 on one wire feeding wheel 6 is rotatably disposed on the side beam 11, and the support shaft 10 on the other wire feeding wheel 6 is slidably disposed on the side beam 11 through a movable sleeve 12, and the movable sleeve 12 and the side beam 11 are connected by a spring piece 26.

[0030] Because the gap between the two feed rollers 6 is limited, when the thread end passes between the two feed rollers 6, there will be two cords on the two feed rollers 6 at the same time. At this time, the two cords will push the feed rollers 6 on the moving sleeve 12 to move, increasing the gap between the two feed rollers 6. The circular groove 7 always limits the position of the cord. The moving sleeve 12 moves on the side beam 11, and the spring piece 26 undergoes elastic deformation. Using this mode, the two feed rollers 6 can hold one cord and transport it stably, or hold two cords and transport them stably.

[0031] Furthermore, the auxiliary structure also includes a support plate 13 and a conductive ring 31 disposed on the movable sleeve 12, and the conductive ring 31 is fitted on the corresponding support shaft 10, and the conductive ring 31 is electrically connected to the conductive layer on the corresponding wire feeding wheel 6. Two auxiliary wheels 14 are rotatably mounted on the support plate 13. The two auxiliary wheels 14 are driven by the conductive belt 15. When the movable sleeve 12 moves, the conductive ring 31 contacts the conductive belt 15 and is electrically connected to each other.

[0032] When two feed rollers 6 are feeding a single cord, the conductive ring 31 and the conductive strip 15 are separated. At this time, no discharge phenomenon occurs between the two conductive layers. When two cords are fed between the two feed rollers 6, the moving sleeve 12 moves, and the conductive ring 31 moves toward the conductive strip 15 and becomes electrically connected to each other. The external power supply transmits electrical energy to the corresponding circular groove 7 through the conductive strip 15 and the conductive ring 31, so that discharge can occur between the two circular grooves 7. Using the above structure, the power supply and de-energization of the conductive layer can be automatically controlled according to the number of cords. Furthermore, by utilizing the cooperation between the conductive strip 15 and the conductive ring 31, the conductive strip 15 can undergo a slight deformation, so that a part of the conductive strip 15 can adhere to the conductive ring 31, achieving a surface contact mode between the conductive strip 15 and the conductive ring 31. When the support shaft 10 and the conductive ring 31 rotate, the conductive ring 31 will drive the conductive strip 15 and the two auxiliary rollers 14 to rotate, thereby avoiding friction between the conductive strip 15 and the conductive ring 31.

[0033] Furthermore, the conductive strip 15 is composed of a conductive layer 16, a rubber layer 17 located outside the conductive layer 16, and a plurality of conductive sheets 18 disposed on the rubber layer 17, wherein the conductive sheets 18 are electrically connected to the conductive layer 16, and the plurality of conductive sheets 18 are equidistantly distributed on the rubber layer 17.

[0034] At most one of the conductive sheets 18 is in contact with the conductive ring 31. Thus, when the conductive belt 15 and the conductive ring 31 are running, the conductive sheets 18 are intermittently electrically connected to the conductive ring 31, thereby causing the conductive layer on the pay-off reel 6 to discharge intermittently, so that the welding points on the two cords between the two pay-off reels 6 are evenly distributed. The above structure can effectively reduce the number of welding points and avoid the overlapping area of ​​the two cords being welded as a whole during continuous discharge, thereby reducing power loss.

[0035] Furthermore, the support plate 13 is vertically slidably mounted on the side beam 11; The wire feeding structure 2 also includes a synchronous wheel 19 rotatably mounted on the side beam 11. Two synchronous rods 20 are rotatably mounted on the synchronous wheel 19, and the two synchronous rods 20 are rotatably connected to the movable sleeve 12 and the support plate 13 on the side beam 11, respectively. The axis of rotation of the synchronous pulley 19 is located between the movable sleeve 12 and the support plate 13.

[0036] When the movable sleeve 12 moves, it can drive the synchronous wheel 19 to rotate via the synchronous rod 20. The synchronous wheel 19, through the synchronous rod 20 on the support plate 13, drives the support plate 13 to move toward the movable sleeve 12, thereby bringing the movable sleeve 12 and the support plate 13 closer together. The conductive ring 31 and the conductive strip 15 move synchronously relative to each other. Using the above structure, when the two feed rollers 6 are feeding one cord, the conductive ring 31 and the conductive strip 15 remain separated and the distance between them is large. When the two feed rollers 6 are feeding two cords, the movable sleeve 12 moves, and the support plate 13 will also actively move closer to the movable sleeve 12, thereby bringing the conductive strip 15 and the conductive ring 31 into contact. If only the conductive ring 31 moves and moves closer to the conductive strip 15, then even when the conductive strip 15 and the conductive ring 31 are separated, the distance between them cannot be too large, otherwise the conductive ring 31 cannot contact the conductive strip 15.

[0037] Furthermore, a first baffle 21 and a second baffle 22 are slidably arranged on the rotating roller 5. The first baffle 21 is connected to the long plate 4 by a spring 23. The second baffle 22 is provided with several insert rods 24. Several slots 25 are opened at the end of the rotating roller 5. The slots 25 are used in conjunction with the insert rods 24.

[0038] Both baffle 1 21 and baffle 2 22 can slide on the rotating roller 5, and baffle 2 22 can be secured to the outer wall of the rotating roller 5 via the insert rod 24 and the slot 25; Figure 5 As shown, the slot 25 is right-angled, with one right-angled side along the axis of the rotating roller 5 and the end of the right-angled side extending to the end face of the rotating roller 5. The other right-angled side is along the circumference of the rotating roller 5. Thus, when installing the second baffle 22, simply insert the insert rod 24 into the slot 25 corresponding to the opening of the slot 25 at the end of the rotating roller 5, and then rotate the second baffle 22 by a specified angle so that the insert rod 24 is inserted into the right-angled side of the slot 25 along the circumference of the rotating roller 5. This completes the installation of the second baffle 22. When it is necessary to assemble the coil, place the second baffle 22 downwards, put the coil on the rotating roller 5, and make the end face of the coil contact the first baffle 21. Then assemble the second baffle 22 onto the rotating roller 5. At this time, the spring 23 presses and fixes the coil through the first baffle 21.

[0039] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
