Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, and in particular to an automatic bobbin winding machine. Background Technology

[0002] In the wire manufacturing process, the winding machine is a key piece of equipment for facilitating subsequent storage, transportation, and use. Its core function is to orderly wind the processed wire onto the surface of the spool, forming a neat coil. To ensure that the wire evenly covers the spool and avoids local accumulation, most mainstream winding machines are equipped with a reciprocating motion guide. This component adjusts the winding position of the wire in real time through a lateral reciprocating motion synchronized with the rotation rhythm of the spool, guiding the wire to be distributed alternately along a straight line.

[0003] However, there is usually a certain gap between the guide and the spool. When the wire is conveyed from the guide outlet to the spool surface, due to factors such as the rigidity of the wire itself, the wire cannot be accurately positioned according to the trajectory set by the guide. This can easily lead to large errors, resulting in loose winding, and some wire deviating from the preset winding track, causing the wire at the edge of the spool to bulge or dent, and the winding precision is generally not high. Utility Model Content

[0004] To solve the above problems, this utility model provides an automatic bobbin winding machine.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic bobbin winding machine, including a bottom frame, a middle frame on the bottom frame, a winding roller rotatably mounted on the middle frame, a drive assembly for driving the winding roller to rotate on the bottom frame, a rotating shaft rotatably mounted on the middle frame, the rotating shaft being parallel to the winding roller, a rotating seat rotatably mounted on the rotating shaft, a mounting box mounted on the rotating seat, a pressure roller rotatably mounted on the side of the mounting box adjacent to the winding roller, an opening on the side of the mounting box adjacent to the winding roller, a toggle member slidably mounted in the opening along the length direction of the winding roller, a reciprocating assembly for driving the toggle member to reciprocate on the mounting box, a connecting rod on the side of the rotating seat adjacent to the winding roller, and a tension spring between the connecting rod and the bottom frame.

[0006] By adopting the above technical solution, a bottom frame, a middle frame, a winding roller, and a rotating shaft are set up. During operation, the spool is placed on the winding roller, and the wire passes sequentially through the actuating component and the pressure roller before connecting to the spool. The tension spring provides a continuous pulling force to the rotating seat, ensuring that the pressure roller always tightly clamps the wire between the pressure roller and the winding roller, effectively preventing the wire from loosening or shifting during the winding process. The drive assembly drives the winding roller to rotate clockwise, providing the core power for wire winding. At the same time, the reciprocating assembly drives the actuating component to reciprocate along the length of the winding roller, which can evenly distribute the wire on the spool surface, preventing local accumulation of wire and ensuring the regularity of the winding. The clamping action of the pressure roller also has a compacting effect on the wire during the winding process, increasing the winding density of the wire on the spool. This ensures that the wire is flush at the edge of the spool, resulting in a more aesthetically pleasing wire roll.

[0007] Furthermore, the reciprocating assembly includes a reciprocating lead screw that is horizontally rotatably disposed within the mounting box, and the actuating component is provided with a connecting plate on one side of the mounting box, and a reciprocating nut that cooperates with the reciprocating lead screw is provided on the connecting plate.

[0008] By adopting the above technical solution, a connecting plate and a reciprocating screw are set up. When the reciprocating screw rotates horizontally, it can drive the actuating component to make a stable reciprocating linear motion along the length direction of the winding roller through the helical transmission with the reciprocating nut on the connecting plate.

[0009] Furthermore, the mounting box is equipped with a slide rail, the length direction of which is consistent with the length direction of the reciprocating lead screw, and the connecting plate is slidably connected to the slide rail via a slider.

[0010] By adopting the above technical solution and setting up slide rails and sliders, precise guidance is provided for the movement of the connecting plate.

[0011] Furthermore, the drive assembly includes a drive motor horizontally mounted on the bottom frame, a first active synchronous pulley fixedly mounted on the output shaft of the drive motor, a first driven synchronous pulley fixedly mounted on the winding roller, and the first active synchronous pulley and the first driven synchronous pulley connected by a first synchronous belt.

[0012] By adopting the above technical solution, a drive motor, a first active synchronous pulley, and a first driven synchronous pulley are set up. The drive motor drives the first active synchronous pulley to rotate, and the first driven synchronous pulley and the winding roller are driven to rotate through the first synchronous belt.

[0013] Furthermore, a second driving synchronous pulley is fixedly sleeved on the winding roller, and a second driven synchronous pulley is fixedly sleeved on the rotating shaft. The second driving synchronous pulley and the second driven synchronous pulley are connected by a second synchronous belt. A circular hole concentric with the reciprocating screw and penetrating the mounting box is opened on the rotating seat. A circular shaft connected to the reciprocating screw is rotatably arranged in the circular hole. A driven sprocket is fixedly sleeved on the circular shaft, and a driving sprocket is fixedly sleeved on the rotating shaft. The driving sprocket and the driven sprocket are connected by a chain.

[0014] By adopting the above technical solution, a second active synchronous pulley and a second driven synchronous pulley are set up. When the winding roller rotates, the second active synchronous pulley, the second synchronous belt and the second driven synchronous pulley work together to drive the rotating shaft to rotate synchronously. The rotating shaft then drives the reciprocating screw to rotate through the transmission of the active sprocket, the chain and the driven sprocket, and finally realizes the reciprocating motion of the actuating component.

[0015] Furthermore, a square tube is vertically arranged on the middle layer frame, a square rod is slidably arranged inside the square tube, a threaded hole is horizontally opened on the square tube, a bolt is spirally arranged in the threaded hole, a crossbar is arranged at the upper end of the square rod, and a tension roller is rotatably arranged on the crossbar, the tension roller is in contact with the outer belt surface of the second synchronous belt.

[0016] By adopting the above technical solution, a square tube, a square rod, and a tension roller are set up. The tension roller is in contact with the outer surface of the second synchronous belt. When the second synchronous belt becomes loose during long-term use, the bolts are loosened, the square rod is slid down, and the tension roller is moved until the second synchronous belt returns to a suitable tension. Then the bolts are tightened to fix the position of the square rod.

[0017] Furthermore, a horizontal bar is provided on the middle shelf, a first clamping piece is provided on the horizontal bar, an installation rod is concentrically provided on the first clamping piece, a second clamping piece is slidably sleeved on the installation rod, a stop is provided at the end of the installation rod away from the first clamping piece, a compression spring is sleeved on the rod body of the installation rod located between the stop and the second clamping piece, a top shelf is provided on the middle shelf, a fixing rod is provided on the top shelf, and a guide roller is rotatably provided on the fixing rod.

[0018] By adopting the above technical solution, a first clamp and a second clamp are set. The wire passes over the mounting rod and is located between the first clamp and the second clamp. The compression spring pushes the second clamp to move towards the first clamp, providing clamping force for the wire and controlling the tightness of the wire. This effectively prevents the wire from becoming loose or sagging during the conveying process and ensures that the wire between the mounting rod, guide roller, and actuating component can be kept taut.

[0019] Furthermore, an L-shaped plate is provided at the end of the fixed rod, and a rotating shaft is provided on the horizontally rotatable vertically on the L-shaped plate. A rotating seat is provided at the lower end of the rotating shaft, and the guide roller is rotatably connected to the rotating seat.

[0020] By adopting the above technical solution, with the L-shaped plate, rotating shaft, and rotating seat, the actuating component will continuously reciprocate along the length of the winding roller. This movement ensures that the angle between the actuating component and the guide roller is always dynamically changing. When the angle between the actuating component and the guide roller changes, the wire will exert a slight lateral force on the guide roller. This force can drive the rotating seat to rotate around the rotating shaft, thereby causing the guide roller to adjust its guiding angle accordingly.

[0021] Furthermore, the actuating element includes an actuating plate and a U-shaped groove disposed on the actuating plate.

[0022] By adopting the above technical solution, a toggle plate and a U-shaped groove are set up, and the U-shaped groove can limit the movement of the wire.

[0023] In summary, this utility model has the following beneficial effects: In this application, a bottom frame, a middle frame, a winding roller, and a rotating shaft are provided. During operation, the spool is fitted onto the winding roller, and the wire passes sequentially around the actuating component and the pressure roller before connecting to the spool. The tension spring provides a continuous pulling force to the rotating seat, ensuring that the pressure roller always tightly clamps the wire between the pressure roller and the winding roller, effectively preventing the wire from loosening or shifting during winding. The drive assembly drives the winding roller to rotate clockwise, providing the core power for wire winding. Simultaneously, the reciprocating assembly drives the actuating component to reciprocate along the length of the winding roller, evenly distributing the wire on the spool surface, preventing localized accumulation and ensuring the regularity of the winding. The clamping action of the pressure roller also compacts the wire during winding, increasing the winding density on the spool. This ensures that the wire is flush at the edges of the spool, resulting in a more aesthetically pleasing wire roll. Attached Figure Description

[0032] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0033] like Figure 1-7As shown in the figure, this application discloses an automatic bobbin winding machine, including a bottom frame 10, a middle frame 11, a winding roller 12, and a rotating shaft 30. The middle frame 11 is disposed on the bottom frame 10, and the winding roller 12 is horizontally rotatably disposed on the middle frame 11. A drive assembly 20 is disposed on the bottom frame 10 for driving the winding roller 12 to rotate. The rotating shaft 30 is rotatably disposed on the middle frame 11 and is parallel to the winding roller 12. A rotating seat 31 is rotatably disposed on the rotating shaft 30, and a mounting box 32 is disposed on the rotating seat 31. A pressure roller 33 is also rotatably disposed on the side of the mounting box 32 adjacent to the winding roller 12. An opening 34 is opened on the side of the mounting box 32 adjacent to the winding roller 12. A toggle member 35 is slidably disposed in the opening 34 along the length direction of the winding roller 12. A reciprocating assembly 40 is disposed on the mounting box 32 to drive the toggle member 35 to reciprocate. A connecting rod 36 is disposed on the side of the rotating seat 31 adjacent to the winding roller 12, and a tension spring 37 is disposed between the connecting rod 36 and the bottom frame 10. During operation, the spool is fitted onto the winding roller 12. The connection method between the spool and the winding roller 12 is existing technology and will not be described in detail here. The wire passes sequentially through the actuating element 35 and the pressure roller 33 before connecting to the spool. The tension spring 37 provides a continuous pulling force to the rotating seat 31, which keeps the pressure roller 33 tightly clamping the wire between the pressure roller 33 and the winding roller 12, effectively preventing the wire from loosening or shifting during the winding process. The drive assembly 20 drives the winding roller 12 to rotate clockwise, providing the core power for the wire winding. At the same time, the reciprocating assembly 40 drives the actuating element 35 to reciprocate along the length of the winding roller 12, which can evenly distribute the wire on the surface of the spool, prevent local accumulation of wire, and ensure the regularity of the winding. The clamping action of the pressure roller 33 also has a compacting effect on the wire during the winding process, increasing the winding density of the wire on the spool. This ensures that the wire is flush at the edge of the spool, making the wire roll more aesthetically pleasing.

[0034] Specifically, the mounting box 32 has two extension plates located below the opening 34 on the side near the winding roller 12, and the pressure roller 33 is rotatably positioned between the two extension plates. A horizontal bar 70 is mounted on the middle layer frame 11, a first clamping piece 71 is mounted on the horizontal bar 70, a mounting rod 72 is concentrically mounted on the first clamping piece 71, a second clamping piece 73 is slidably mounted on the mounting rod 72, a stop 74 is mounted on the end of the mounting rod 72 away from the first clamping piece 71, and a compression spring 75 is mounted on the rod body of the mounting rod 72 located between the stop 74 and the second clamping piece 73. A top layer frame 13 is mounted on the middle layer frame 11, a fixing rod 80 is mounted on the top layer frame 13, and a guide roller 81 is rotatably mounted on the fixing rod 80. The wire passes over the mounting rod 72 and is positioned between the first clamp 71 and the second clamp 73. A compression spring 75 pushes the second clamp 73 towards the first clamp 71, providing clamping force to the wire and controlling its tension. This effectively prevents the wire from slackening or sagging during transport, ensuring the wire remains taut between the mounting rod 72, the guide roller 81, and the actuating element 35. This tautness not only reduces path deviation caused by wire movement but also prevents unnecessary friction and scratching between the wire and other equipment components, reducing the risk of wire wear. The actuating element 35 continuously reciprocates along the length of the winding roller 12, causing the connection angle between the actuating element 35 and the guide roller 81 to remain dynamically changing. To avoid wire stretching and deformation, and path deviation caused by improper angle, an L-shaped plate 82 is provided at the end of the fixed rod 80. The vertical section of the L-shaped plate 82 is connected to the fixed rod 80, and a rotating shaft 83 is provided for vertical rotation in the horizontal direction. A rotating seat 84 is provided at the lower end of the rotating shaft 83, and the guide roller 81 is rotatably connected to the rotating seat 84. When the angle between the actuating element 35 and the guide roller 81 changes, the wire will exert a slight lateral force on the guide roller 81. This force can drive the rotating seat 84 to rotate around the rotating shaft 83, thereby causing the guide roller 81 to adjust its guiding angle accordingly. This dynamic adjustment mechanism ensures that the guide roller 81 always maintains a suitable angle with the wire between the actuating element 35 and the guide roller 81, ensuring that the wire is always transported along a smooth path.

[0035] During setup, the reciprocating assembly 40 includes a reciprocating lead screw 41 horizontally rotatably mounted within the mounting box 32. The reciprocating lead screw 41 is parallel to the rotating shaft 83. A connecting plate 42 is located on one side of the actuating element 35 within the mounting box 32, and a reciprocating nut 43 that mates with the reciprocating lead screw 41 is mounted on the connecting plate 42. When the reciprocating lead screw 41 rotates horizontally, the helical transmission with the reciprocating nut 43 on the connecting plate 42 drives the actuating element 35 to reciprocate linearly along the length of the winding roller 12. The reciprocating lead screw 41 provides smooth transmission and can precisely control the reciprocating speed and stroke of the actuating element 35, further ensuring the uniformity of the wire winding on the spool and avoiding wire arrangement disorder caused by deviations in the movement of the actuating element 35. A slide rail 38 is provided within the mounting box 32, with its length aligned with the length of the reciprocating lead screw 41. The connecting plate 42 is slidably connected to the slide rail 38 via a slider. The slide rail 38 and slider provide precise guidance for the movement of the connecting plate 42. When the reciprocating screw 41 drives the connecting plate 42 to move the actuating component 35, the cooperation between the slide rail 38 and the slider can limit the movement direction of the connecting plate 42, preventing the connecting plate 42 from deviating or wobbling during the movement, ensuring that the actuating component 35 always moves stably along the set trajectory, further improving the stability and reliability of the reciprocating assembly 40 transmission, and indirectly ensuring the uniformity of wire winding.

[0036] The drive assembly 20 includes a drive motor 21 horizontally mounted on the bottom frame 10. A first driving synchronous pulley 22 is fixedly sleeved on the output shaft of the drive motor 21, and a first driven synchronous pulley 23 is fixedly sleeved on the winding roller 12. The first driving synchronous pulley 22 and the first driven synchronous pulley 23 are connected by a first synchronous belt 24. The drive motor 21 drives the first driving synchronous pulley 22 to rotate, which in turn drives the first driven synchronous pulley 23 and the winding roller 12 to rotate via the first synchronous belt 24. A second driving synchronous pulley 50 is also fixedly sleeved on the winding roller 12, and a second driven synchronous pulley 51 is fixedly sleeved on the rotating shaft 30. The second driving synchronous pulley 50 and the second driven synchronous pulley 51 are connected by a second synchronous belt 52. When the winding roller 12 rotates, the second driving synchronous pulley 50, the second synchronous belt 52, and the second driven synchronous pulley 51 work together to drive the rotating shaft 30 to rotate synchronously. The rotating base 31 has a circular hole concentric with the reciprocating lead screw 41 and passing through the mounting box 32. A circular shaft 53, connected to the reciprocating lead screw 41, is rotatably mounted within the circular hole. The circular shaft 53 is parallel to the rotating shaft 30. A driven sprocket 54 is fixedly sleeved on the circular shaft 53, and a driving sprocket 55 is fixedly sleeved on the rotating shaft 30. The driving sprocket 55 and the driven sprocket 54 are connected by a chain 56. The rotating shaft 30 drives the reciprocating lead screw 41 to rotate through the transmission of the driving sprocket 55, chain 56, and driven sprocket 54, ultimately realizing the reciprocating motion of the actuating element 35. This power transmission method eliminates the need for an independent drive source for the reciprocating lead screw 41, reducing the number of power components in the equipment and lowering manufacturing costs.

[0037] In the specific setup, a square tube 60 is vertically mounted on the middle frame 11, and a square rod 61 is slidably mounted inside the square tube 60. A threaded hole is horizontally opened on the square tube 60, and a bolt 62 is screwed into the threaded hole. A crossbar 63 is mounted at the upper end of the square rod 61, and a tension roller 64 is rotatably mounted on the crossbar 63. The tension roller 64 contacts the outer surface of the second synchronous belt 52. When the second synchronous belt 52 becomes loose during long-term use, the bolt 62 is loosened, the square rod 61 is slid downwards, and the tension roller 64 is moved until the second synchronous belt 52 regains its appropriate tension. Then, the bolt 62 is tightened to fix the position of the square rod 61. This effectively eliminates the impact of synchronous belt slack on power transmission, ensuring the stability and reliability of the second synchronous belt 52 transmission. It also avoids the problem of the rotational speed of the rotating shaft 30 fluctuating due to slippage of the second synchronous belt 52, which in turn affects the reciprocating motion accuracy of the actuating component 35. This improves the ease of maintenance and long-term operational stability of the equipment's transmission system.

[0038] The actuating element 35 includes an actuating plate 351 and a U-shaped groove 352 disposed on the actuating plate 351. The U-shaped groove 352 can limit the movement of the wire. When the wire passes through the U-shaped groove 352, the two side walls of the U-shaped groove 352 can restrict the lateral displacement of the wire, preventing the wire from falling off the actuating element 35 during its reciprocating motion, ensuring that the wire always moves along the set path. At the same time, the opening 34 of the U-shaped groove 352 facilitates the installation and removal of the wire. When changing the wire or spool, the wire can be quickly placed into or removed from the U-shaped groove 352, improving the convenience of operation.

[0039] The rotating shaft 30 includes a first shaft and a second shaft respectively rotatably mounted on the middle shelf 11. The first shaft and the second shaft are rotatably connected. A second driven synchronous pulley 51 and a driving sprocket 55 are fixedly sleeved on the second shaft. A rotating seat 31 is rotatably sleeved on the second shaft. A control cabinet 131 is mounted on the top shelf 13. A controller is installed inside the control cabinet 131. Control buttons are installed on the control cabinet 131. The controller receives signals from the control buttons to control the drive motor 21.

[0040] In one possible implementation, the middle shelf 11 is rotatably equipped with first pass rollers 90 at its upper and lower parts, and a second pass roller 91 is rotatably equipped above the horizontal bar 70. The top shelf 13 is rotatably equipped with two vertically spaced rotating rods above the second pass rollers 91, and several third pass rollers 92 are fixedly sleeved on the rotating rods. The wire first passes over the horizontal bar 70, then passes upward over the first pass roller 90 at the lower part of the middle shelf 11, and then passes upward over the second pass roller 91 above the horizontal bar 70 of the middle shelf 11; then it enters the area of ​​the third pass rollers 92 of the top shelf 13, and is interlaced between the third pass rollers 92 carried by the two vertically spaced rotating rods. After the winding is completed, it is led out from the third pass roller 92 of the lower rotating rod, and finally passes forward over the guide roller 81, and enters the subsequent process of the actuating member 35 and the pressure roller 33 to buffer the tension of the wire.

[0041] The operating principle of the automatic bobbin winding machine in this embodiment is as follows: First, the bobbin is placed on the winding roller 12. Then, the wire is sequentially passed around the rod body of the mounting rod 72 located between the first clamp 71 and the second clamp 73, the guide roller 81, the U-shaped groove 352 on the actuating plate 351, and the pressure roller 33, and finally connected to the bobbin. Subsequently, the drive motor 21 is started to drive the first driven synchronous pulley 23 and the winding roller 12 to rotate clockwise through the first active synchronous pulley 22 and the first synchronous belt 24, providing power for the winding of the wire. At the same time, the winding roller 12 drives the rotating shaft 30 to rotate synchronously through the second active synchronous pulley 50 and the second synchronous belt 52. The rotating shaft 30 then drives the reciprocating screw 41 in the mounting box 32 to rotate through the active sprocket 55, the chain 56, and the driven sprocket 54. The reciprocating screw 41, through its cooperation with the reciprocating nut 43 on the connecting plate 42, drives the actuating element 35 to move back and forth along the length of the winding roller 12, so that the wire is evenly distributed on the surface of the bobbin. During this process, the tension spring 37 between the connecting rod 36 on the rotating seat 31 and the bottom frame 10 continuously pulls the rotating seat 31 closer to the winding roller 12, so that the pressure roller 33 always clamps the wire between the pressure roller 33 and the winding roller 12, preventing the wire from loosening and shifting and increasing the winding density. At the same time, the clamping force of the first clamping piece 71 and the second clamping piece 73 on the wire ensures that the wire is taut during the conveying process, reducing path deviation, and finally achieving neat and tight winding of the wire on the spool.

All technical solutions falling within the scope of this utility model's concept are protected.
