[0001] This utility model relates to the field of winding machine technology, specifically to an automatic winding machine for changing rolls. Background Technology

[0002] In the field of textile technology, finished yarns need to be wound up. Traditional winding devices usually only have one winding shaft. When the wound yarn bundle reaches the set value, the machine needs to be stopped, the wound finished product needs to be removed, and a new winding shaft needs to be installed for the next winding. In the dual-station automatic winding mechanism provided by patent CN201920535793.5, the cutting component includes a threading part (71) and a cutting part (72) disposed on one side of the threading part (71) and cooperating with the threading part (71). After changing the roll, it is necessary to manually thread the wire back into the threading part. This is a semi-automatic winding mechanism. Compared with manual winding, the operation is simplified, but the degree of mechanization is not high. Therefore, this automatic winding machine was designed. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic winding machine that changes the position of the winding roller by rotating the gear, so that the yarn is wound around the cutter shaft. The reciprocating motion of the yarn brings the yarn into contact with the cutter, cutting the yarn. The yarn at the cut is clamped on the reciprocating conveying mechanism and another winding roller, so that the yarn is wound around the winding roller, thus realizing the winding change.

[0004] This utility model provides the following technical solution: an automatic winding machine with rewinding function, comprising a frame, characterized in that: a winding and rewinding mechanism is connected to the back of the frame, and a rotating plate is connected to the front of the frame; the winding and rewinding mechanism includes a rotating gear and a limiting wheel; the limiting wheel is rotatably connected to the back of the frame, and the rotating gear is located inside the limiting wheel; the rotating plate is connected to the front of the rotating gear; two symmetrical winding rollers are rotatably connected to the rotating gear; the two ends of the winding rollers are located on both sides of the frame; a cutter shaft is fixed on the rotating plate, and a cutter is fixed on the cutter shaft; the cutter shaft and the winding rollers are evenly distributed on the rotating plate, and the axis of the cutter shaft is perpendicular to the axis of the winding rollers; a reciprocating conveying mechanism is installed on the frame; after the winding rollers are repositioned, the cutter shaft is located between the reciprocating conveying mechanism and the winding rollers, cutting the wire.

[0005] To rotate the rotating gear and adjust the position of the take-up roller, a side gear meshes on the outer edge of the rotating gear. The side gear is rotatably connected to the back of the frame via a mounting bracket, and a motor is connected to the back of the side gear.

[0006] To keep the timing belt taut, a tensioning wheel is also connected to the rotating gear. The tensioning wheel is located on the side of the timing belt, and a fixing plate with a waist hole is connected to the lower end of the tensioning wheel. The fixing plate is fixed to the rotating gear by bolts.

[0007] To enable the take-up rollers to rotate, a motor connecting rod is fixed to the outside of the rotating gear, and two motors are fixed on the motor connecting rod. A central roller is provided between the take-up rollers, and the central roller is connected to the rotating gear by a bearing. The motor drives the central roller to rotate through a synchronous belt, and the central roller and the take-up roller are connected by a synchronous pulley and a synchronous belt.

[0008] To adjust the position of the reciprocating conveying mechanism, the wire is clamped between the reciprocating conveying mechanism and the take-up roller. The frame has a waist-shaped hole. The reciprocating conveying mechanism includes a panel inserted into the frame. A cylinder is connected to the lower end of the panel.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1 to 5 This utility model provides a technical solution: an automatic roll-changing winding machine, including a frame 1, a winding and changing mechanism 8 connected to the back of the frame 1, and a rotating plate 2 connected to the front of the frame 1. The winding and changing mechanism 8 includes a rotating gear 89 and a limiting wheel 86. The limiting wheel 86 is rotatably connected to the back of the frame 1 via a pin, and the limiting wheel 86 limits the position of the rotating gear 89, causing the rotating gear 89 to rotate within the limiting wheel 86. The rotating gear 89 is located inside the limiting wheel 86. The rotating plate 2 is connected to the front of the rotating gear 89, and the rotating gear 89 drives the rotating plate 2 to rotate. Two symmetrical winding rollers 81 are rotatably connected to the rotating gear 89, with the two ends of the winding rollers 81 located on both sides of the frame 1. A cutter shaft 810 is fixed on the rotating plate 2, and a cutter 811 is fixed on the cutter shaft 810. The cutter shaft 81 and the take-up roller 81 are evenly distributed on the rotating plate 2, and the axis of the cutter shaft 810 and the axis of the take-up roller 81 are perpendicularly distributed. A reciprocating conveyor mechanism 7 is installed on the frame 1. The yarn is led out from the reciprocating conveyor mechanism 7 and wound on the take-up roller 81. When the take-up roller 81 changes position, the reciprocating conveyor mechanism 7 will move outward to make room. The cutter shaft 810 is located between the reciprocating conveyor mechanism 7 and the take-up roller 81, supporting the yarn, and the yarn continues to reciprocate. At the same time, the reciprocating conveyor mechanism 7 resets and moves to the left to fit against another take-up roller 81. When the yarn reciprocates and contacts the cutter on the cutter shaft 810, the yarn will be cut. The cut yarn is clamped between the reciprocating conveyor mechanism 7 and the other take-up roller 81. The rotation of the other take-up roller 81 will wind the yarn onto the take-up roller 81, realizing automatic roll changing.

[0017] like Figure 4 and 5 As shown, a side gear 84 meshes on the outer edge of the rotating gear 89. The side gear 84 is rotatably connected to the back of the frame 1 via the mounting bracket 88. A motor 87 is connected to the back of the side gear 84. The motor 87 drives the side gear 84 to rotate, which in turn drives the rotating gear 89 to rotate, adjusting the position of the symmetrical winding rollers 81 on both sides, and driving the winding and changing mechanism 8 to operate, thereby realizing the changing of the roll.

[0018] A tensioning wheel 85 is bolted to the rotating gear 89. The tensioning wheel 85 is located on the side of the timing belt. A fixing plate with a waist hole is connected to the lower end of the tensioning wheel 85. The tensioning wheel 85 is connected to the top of the fixing plate through a bearing and a shaft. The fixing plate is fixed to the rotating gear 89 by bolts. The position of the bolt in the waist hole can adjust the position of the tensioning wheel 85 to ensure that the timing belt is in a taut state.

[0019] A motor connecting rod 83 is fixed to the outside of the rotating gear 89. Two motors are fixed on the motor connecting rod 83. A central roller 82 is arranged between the take-up rollers 81. The central roller 82 is connected to the rotating gear 89 by a bearing. The motor drives the central roller 82 to rotate through a synchronous belt. Multiple synchronous pulleys are sleeved and fixed on the central roller 82. The synchronous pulleys of the central roller 82 are connected to the synchronous pulleys on the take-up rollers 81 through a synchronous belt, so that one motor can drive two take-up rollers 81 to rotate at the same time, while the other motor is a spare motor.

[0020] like Figure 6 and 7 As shown, the frame 1 has a waist-shaped hole. The reciprocating conveying mechanism 7 includes a panel 73 inserted into the frame 1. The panel 73 is inserted into the waist-shaped hole. The lower end of the panel 73 is connected to a cylinder 74 via a pin. One end of the cylinder 74 is connected to the panel 73. The telescopic end of the cylinder 74 is connected to a T-shaped seat on the frame 1 via bolts. A guide rail 71 is connected to the back of the frame 1. A connecting plate 72 is fixed on the sliding part of the guide rail 71. The connecting plate 72 is connected to the panel 73. The sliding between the guide rail 71 and the connecting plate 72 guides the movement of the panel 73, so that the reciprocating conveying mechanism 7 moves along the guide rail 71 smoothly.

[0021] Side plates 75 are fixed to both ends of the panel 73. An upper roller 76 and a side roller 77 are rotatably connected between the side plates 75. Both the upper roller 76 and the side roller 77 guide the yarn. A mounting plate is connected to the side of the side plate 75. Rollers 78 are rotatably connected to both ends of the mounting plate. A motor is also mounted on the mounting plate. A synchronous pulley is connected to the output end of the motor. A synchronous belt is also connected between the synchronous pulley and the roller 78. A yarn guide clamp 711 is connected to the synchronous belt. By reciprocating rotation of the motor, the reciprocating motion of the synchronous belt is controlled, so that the yarn guide clamp 711 drives the yarn to reciprocate above the mounting plate, so that the yarn is evenly distributed on the take-up roller 81.

[0022] A reciprocating slide rail 79 is fixed to the mounting plate by bolts. A sliding block 710 slides on the reciprocating slide rail 79. The sliding block 710 is located below the synchronous belt. The wire guide clamp 711 and the sliding block 710 are respectively clamped on the upper and lower ends of the synchronous belt. The reciprocating slide rail 79 guides the movement of the sliding block 710, which in turn guides the movement of the wire guide clamp 711, making the reciprocating movement of the wire guide clamp 711 and the wire smoother.

[0023] like Figure 1 and 2As shown, the front of the frame 1 is also connected to the guide wheel 3, traction wheel 4, traction inclined wheel 5, tension rod 6, and guide wheel 9. The guide wheel 3, traction wheel 4, traction inclined wheel 5, tension rod 6, and guide wheel 9 are distributed above the reciprocating conveying mechanism 7. The wire passes through the guide wheel 3, traction wheel 4, traction inclined wheel 5, tension rod 6, guide wheel 9, reciprocating conveying mechanism 7, and take-up roller 81 in sequence. The guide wheel 3, traction wheel 4, and traction inclined wheel 5 guide the take-up of the wire, the tension rod 6 adjusts the tension on the wire, and the reciprocating conveying mechanism 7 is used to evenly and repeatedly wind the wire onto the take-up roller 81.

[0024] A brake seat 10 is also fixed on the frame 1. The brake seat 10 is located on one side of a take-up roller 81. The brake seat 10 is attached to the side of the take-up roller 81 after it has been wound up, so that the take-up roller 81 stops rotating, making it convenient to remove the spool from the take-up roller 81.

[0025] The winding process is as follows: First, the reciprocating conveyor mechanism is shifted to one side to make room, and then the rotating gear is driven to rotate, rotating the fully loaded take-up roller to the side of the brake seat and the unloaded take-up roller to the side of the reciprocating conveyor mechanism. Then, the reciprocating conveyor mechanism is reset. At this time, the yarn is still wound on the fully loaded take-up roller, and the cutter shaft is located between the two take-up rollers, supporting the yarn. The yarn reciprocates and contacts the cutter on the cutter shaft, cutting the yarn. The yarn at the cut is subjected to the pressure of the unloaded take-up roller and the reciprocating conveyor mechanism, which winds the yarn onto the unloaded take-up roller, realizing automatic winding. The rotation of the bobbin on the take-up roller is stopped by the brake seat, which facilitates the replacement of the bobbin and prepares for the next winding.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
