[0003] Due to their usage characteristics, the yarn bobbins for sewing threads and embroidery threads are often small. Therefore, during the rewinding process, the yarn tubes need to be frequently replaced, and the yarn needs to be cut before replacing the yarn tube. If the yarn is manually cut and then the yarn tube is manually replaced, not only is the labor intensity high and the amount of labor is large, but also the production efficiency of the equipment is reduced.

Detailed implementation manners

[0036] Please refer to the attached drawings in the specification Figure 1 to attached drawing Figure 13 As shown, the present utility model is a full-automatic winding machine, which is assembled by a frame 1 and a raw yarn frame 2, an active winding mechanism 3, a yarn guiding mechanism 4, a passive head mechanism 5, a tube clamping mechanism 6, a scissor mechanism 7, a vibrating disk 8 and a tube feeding mechanism 9 etc. installed on the frame 1.

[0037] Among them, the frame 1 is the skeleton of the entire winding machine, which is supported on the ground, and various mechanisms are installed on it.

[0038] The original yarn stand 2 is arranged on the top of the machine frame 1, and a number of large rolls of original yarn 10 are placed thereon. In this embodiment, there are 4 rolls of the large rolls of original yarn 10 to correspond to 4 workstations. The original yarn stand 2 is successively provided with a tensioner 21, a yarn passing roller 22, and a yarn detector 23. The yarn 11 unwound from the original yarn stand 2 adjusts the tension through the tensioner 21 and successively passes through the yarn passing roller 22 and the yarn detector 23, and the yarn detector 23 detects whether the yarn 11 is broken.

[0039] The active winding mechanism 3 and the passive head mechanism 5 are arranged opposite to each other and are provided with a number of groups. In this embodiment, there are 4 groups. A yarn tube 12 is clamped between the active winding mechanism 3 and the passive head mechanism 5. The active winding mechanism 3 rotates to drive the yarn tube 12 to rotate, so as to wind the yarn 11 unwound from the large roll of original yarn 10 onto the yarn tube 12.

[0040] The yarn guiding mechanism 4 is arranged on one side of the active winding mechanism 3 and can reciprocate radially along the yarn tube 12, so as to drive the yarn 11 to move and make the yarn 11 cover the yarn tube 12. Specifically, the yarn guiding mechanism 4 is assembled by a yarn guiding support 41, a vertical plate 42, a yarn guiding motor 43, a transmission shaft 44, a moving screw rod clamp block 45, a moving screw rod 46, a yarn guiding head 47, etc.

[0041] The yarn guiding support 41 is the base of the entire yarn guiding mechanism 4, enabling the yarn guiding mechanism 4 to be manufactured modularly. There are two vertical plates 42, which are welded to the yarn guiding support 41 in parallel and are perpendicularly connected to the yarn guiding support 41.

[0042] The yarn guiding motor 43 is installed on one of the vertical plates 42. In this embodiment, the yarn guiding motor 43 is located between the two vertical plates 42, so as to make full use of the space between the two vertical plates 42 and make the structure of the entire yarn guiding mechanism compact. A main synchronous pulley 431 is connected to the yarn guiding motor 43, and the main synchronous pulley 431 rotates driven by the yarn guiding motor 43.

[0043] The transmission shaft 44 is pivotally connected and supported on the two vertical plates 42, and a passive pulley I 441 and a passive pulley II 442 are respectively installed at both ends thereof. A synchronous belt I 481 is sleeved on the main synchronous pulley 431 and the passive pulley I 441. The yarn guiding motor 43 drives the main synchronous pulley 431, the synchronous belt I 481, and the passive pulley I 441 in sequence, and the passive pulley I 441 drives the transmission shaft 44 in linkage, and the transmission shaft 44 drives the passive pulley II 442 again.

[0044] Further, a driven pulley III 421 is installed on the other vertical plate 42 where the yarn guiding motor 43 is not installed. A synchronous belt II 482 is sleeved on the driven pulley II 442 and the driven pulley III 421, so that the driven pulley II 442 drives the synchronous belt II 482 and the driven pulley III 421 in sequence. In this embodiment, the main synchronous pulley 431, the driven pulley I 441, the driven pulley II 442, and the driven pulley III 421 are arranged in a 2×2 matrix, making the arrangement regular and ensuring that the lengths of the synchronous belt I 481 and the synchronous belt II 482 are the same, with good versatility.

[0045] The moving lead screw clamps 45 are respectively fixed on the synchronous belt I 481 and the synchronous belt II 482, and can be respectively driven by the synchronous belt I 481 and the synchronous belt II 482. The moving lead screws 46 are respectively fixed on the moving lead screw clamps 45 and are driven by the moving lead screw clamps 45 to reciprocate back and forth in the front-rear direction.

[0046] To limit the left-right and up-down positions of the moving lead screw 46, a V-shaped supporting pulley 461 is arranged below the moving lead screw 46, and a pressing pulley 462 is arranged above it. The V-shaped supporting pulley 461 and the pressing pulley 462 are arranged oppositely and clamp the moving lead screw 46. Specifically, the V-shaped supporting pulley 461 can clamp the moving lead screw 46 to limit the left, right, and lower positions of the moving lead screw 46; the pressing pulley 462 presses down on the moving lead screw 46 to prevent the moving lead screw 46 from moving upwards.

[0047] Two mutually parallel moving lead screws 46 are provided. Each moving lead screw 46 is perpendicular to and passes through the yarn guiding bracket 41 and is respectively arranged outside the two vertical plates 42, making the layout reasonable. The two moving lead screws 46 are connected by a connecting rod 463 to prevent the two moving lead screws 46 from rotating.

[0048] The yarn guiding head 47 can hook the yarn 11 and is installed at one end of the moving lead screw 46. In this embodiment, two yarn guiding heads 47 are arranged on each moving lead screw 46, so that the two moving lead screws 46 drive the four yarn guiding heads 47 synchronously and the four yarn guiding heads 47 move synchronously, greatly improving the yarn guiding efficiency.

[0049] The working principle of the yarn guiding mechanism 4 is as follows: The yarn guiding motor 43 rotates forward and backward, and drives the main synchronous pulley 431 in sequence. The main synchronous pulley 431 drives the synchronous belt I 481, the driven pulley I 441, the transmission shaft 44, the driven pulley II 442, the synchronous belt II 482, and the driven pulley III 421 in sequence. The above transmission is realized through the synchronous belt and the pulley, with stable transmission, reliable performance, and long service life. The reciprocating movement of the synchronous belt I 481 and the synchronous belt II 482 drives the movement of the moving screw rod clamp 45 in a reciprocating manner. The moving screw rod clamp 45 drives the moving screw rod 46 to move back and forth, and drives the yarn guiding head 47 to guide the yarn through the moving screw rod 46. By controlling the number of rotations of the yarn guiding motor 43, the reciprocating stroke of the synchronous belt I 481 and the synchronous belt II 482 can be adjusted, and thus the stroke of the yarn guiding head 47 can be adjusted arbitrarily to meet different yarn guiding requirements.

[0050] Furthermore, the active winding mechanism 3 and the yarn guiding mechanism 4 are installed on the same yarn guiding bracket 41, which is composed of an active winding motor 31 and several active winding rollers 32 and other components. The active winding motor 31 is installed on the yarn guiding bracket 41, and drives all the active winding rollers 32 to rotate through a transmission belt 33. The active winding roller 32 abuts against the side surface of the yarn tube 12, and drives the yarn tube 12 to rotate through the rotation of the active winding roller 32.

[0051] The tube clamping mechanism 6 is located below the active winding mechanism 3, and can grasp the wound yarn tube 12, so that the yarn tube 12 is separated from between the active winding mechanism 3 and the passive top head mechanism 5, and rotates towards the scissors mechanism 7. After the scissors mechanism 7 cuts the yarn, the tube clamping mechanism 6 releases the yarn tube 12. The tube clamping mechanism 6 is a prior art, so it will not be described in detail here.

[0052] The scissors mechanism 7 is located below the passive top head mechanism 5, and can cut the yarn 11. Specifically, the scissors mechanism 7 is composed of a mounting seat 71, a scissors telescopic cylinder 72, a scissors seat 73, a fixed blade 74, a movable blade 75, a scissors connecting rod 76, and a scissors cylinder 77 and other parts.

[0053] Among them, the mounting seat 71 is fixed to the frame 1 of the winding machine, so that the entire scissors mechanism is installed on the frame 1.

[0054] The scissor telescopic cylinder 72 is installed in the mounting seat 71, which is connected to and pushes the scissor seat 73, so that the scissor mechanism can retract when it does not need to cut the yarn 11, to avoid the scissors from accidentally cutting the yarn 11 or conflicting with other mechanisms of the winding machine (such as the tube clamping mechanism 6, etc.). Specifically, the scissor telescopic cylinder 72 includes a cylinder rod 721, which vertically passes through the mounting seat 71 and is connected to the scissor seat 73, and the scissor seat 73 is pushed to telescope through the cylinder rod 721. A guide rod 722 is respectively provided on both sides of the cylinder rod 721, one end of the guide rod 722 is connected to the scissor seat 73, and is supported on the mounting seat 71 through a linear bearing 723. The guide rod 722 limits the moving direction of the scissor seat 73 to prevent the scissor seat 73 from rotating.

[0055] The fixed blade 74 is fixedly mounted on the scissor seat 73 and moves in conjunction with the scissor seat 73. The movable blade 75 is pivotally connected to the scissor seat 73 and can rotate relative to the fixed blade 74 and cooperate with the fixed blade 74 to cut the yarn 11. That is, when the movable blade 75 and the fixed blade 74 are engaged, the yarn 11 is cut.

[0056] The scissor cylinder 77 is installed on one side of the scissor seat 73, and is connected to and drives the scissor connecting rod 76 to extend and retract, thereby providing power for the shearing action of the scissor mechanism. Since only one scissor cylinder 77 is needed for driving, the structure of the scissor mechanism is simple and the cost is low.

[0057] The scissor link 76 is pivotally connected to the movable blade 75 and can drive the movable blade 75 to open and close. Specifically, the movable blade 75 is provided with a waist hole 751, and the scissor link 76 is provided with a pin 761, which is received in the waist hole 751 and pushes the movable blade 75 to open and close through the pin 761. Further, a plurality of guide blocks 731 are provided at the bottom of the scissor seat 73, and the scissor link 76 passes through the guide blocks 731 to limit the moving direction of the scissor link 76.

[0058] The movable blades 75 are provided with a plurality of blades, all of which are driven simultaneously by the same scissor link 76. Since the scissor link 76 drives a plurality of movable blades 75 simultaneously, the wire cutting efficiency is high, the actions are synchronized, and the labor intensity of the workers is greatly reduced. In this embodiment, the movable blades 75 are specifically provided with 4 blades, which are arranged at equal intervals; each movable blade 75 corresponds to a fixed blade 74.

[0059] The working principle of the scissor mechanism 7 is as follows: When it is necessary to cut the yarn 11, the scissor telescopic cylinder 72 drives the cylinder rod 721 to extend the cylinder rod 721. The cylinder rod 721 drives components such as the scissor seat 73, the fixed blade 74 and the movable blade 75 mounted on the scissor seat 73. During the extension process of the scissor mechanism, the telescopic direction of the scissor mechanism is defined by the guide rod 722. After the scissor mechanism extends, the yarn 11 enters between the fixed blade 74 and the movable blade 75. Then, the scissor cylinder 77 is activated and pulls the scissor link 76. The scissor link 76 drives all the movable blades 75 in a linkage manner, causing the movable blades 75 to close relative to the fixed blade 74, thereby cutting the yarn 11.

[0060] Furthermore, the passive head mechanism 5 and the scissor mechanism 7 are installed on the same mounting seat 71, and it is composed of a passive head cylinder 51, a top plate 52, a top rod 53, a head 54, etc. Among them, the passive head cylinder 51 is installed on the mounting seat 71 and is connected to and drives the top plate 52. A number of the top rods 53 are provided and penetrate through the mounting seat 71. Each top rod 53 is connected to the top plate 52 and is driven by the top plate 52, so that one passive head cylinder 51 can synchronously drive all the top rods 53. One end of the top rod 53 is pivotally connected to the head 54, and the head 54 abuts against the side of the yarn tube 12. A return spring 55 is sleeved on the top rod 53, and the return spring 55 abuts against the top plate 52 to reset the top plate 52.

[0061] The vibrating bowl 8 is docked with the tube feeding mechanism 9, and it can straighten the yarn tubes 12 and send them to the tube feeding mechanism 9. The vibrating bowl 8 is a commercially available product and will not be elaborated here.

[0062] The tube feeding mechanism 9 can load a number of empty yarn tubes 12 and can transport the yarn tubes 12 to between the active winding mechanism 3 and the passive head mechanism 5. Specifically, the tube feeding mechanism 9 is composed of a bottom plate 92, a guide rail 93, a slider 94, a pipe connecting seat 95, a lead screw 96, a conveying motor 97, a hopper 98, a cylinder I 99, etc.

[0063] Among them, the bottom plate 92 is installed on the frame 1. In this embodiment, a bearing seat 91 is installed on the frame 1, and one end of the bottom plate 92 is pivotally connected to the frame 1 through the bearing seat 91, so that the bottom plate 92 can rotate relative to the frame 1. The other end of the bottom plate 92 is provided with a limit block 921, and the limit block 921 is installed on the frame 1 and can abut against the side of the bottom plate 92 to prevent the bottom plate 92 from deflecting during rotation.

[0064] Further, a compression spring seat 13 is provided on the frame 1. A compression spring 14 is provided inside the compression spring seat 13. The compression spring 14 abuts against the bottom of the bottom plate 92 to support the bottom plate 92 and cooperate with the limit block 921 to keep the bottom plate 92 in a horizontal state.

[0065] The guide rail 93 is fixed to the bottom plate 92; the slider 94 cooperates with the guide rail 93 and slides along the guide rail 93.

[0066] The pipe connection seat 95 is installed on the slider 94 and is driven by the slider 94. A plurality of bobbin positioning grooves 951 are provided on the pipe connection seat 95, and each bobbin positioning groove 951 can accommodate one of the bobbins 12. In this embodiment, 4 bobbin positioning grooves 951 are provided, so that 4 bobbins 12 can be conveyed simultaneously, and the bobbin positioning grooves 951 can position the bobbins 12 to prevent the bobbins 12 from rolling.

[0067] The lead screw 96 is pivotally connected to the bottom plate 92 through a lead screw seat 961; the lead screw 96 is screwed with the slider 94, so that the lead screw 96 can drive the slider 94 to reciprocate along the guide rail 93. The conveying motor 97 is installed on the bottom plate 92 and is on the same side as the bearing seat 91. The conveying motor 97 can drive the lead screw 96 to rotate. Specifically, the conveying motor 97 and the lead screw 96 are driven by a synchronous pulley 971 and a synchronous belt 972.

[0068] The hopper 98 is installed on the frame 1 and is located at one end of the guide rail 93. A plurality of bobbins 12 can be accommodated inside it. The hopper 98 is vertically arranged, and clamping arms 981 are provided on both sides thereof. The bobbins 12 are clamped between the clamping arms 981 to prevent the bobbins 12 from falling and to arrange the bobbins 12 in a single stack vertically. A bobbin induction probe 982 is installed on the hopper 98, which can detect whether there are bobbins 12 in the hopper 98, so as to replenish the bobbins 12 in time and ensure that each bobbin positioning groove 951 of the pipe connection seat 95 can receive one bobbin 12.

[0069] The cylinder I 99 is installed at the bottom on one side of the hopper 98 and includes a mandrel 991, which can be inserted into the lowermost bobbin 12 to prevent the bobbin 12 from falling.

[0070] A cylinder II 15 is installed on the frame 1; the cylinder II 15 is connected to one end of the bottom plate 92, and the cylinder II 15 and the bearing seat 91 are located at different ends of the bottom plate 92. The cylinder II 15 can drive the bottom plate 92 to rotate around the bearing seat 91 to tilt the pipe connection seat 95.

[0071] The working principle of the pipe feeding mechanism 9 is as follows:

[0072] 1), The bobbin induction probe 982 detects whether there is a bobbin 12 in the hopper 98. If there is no bobbin 12, the vibrating disk 8 is started to automatically add bobbins 12 into the hopper 98 for use. At this time, the mandrel 991 of the cylinder I99 is inserted into the bottommost bobbin 12 to prevent the bobbin 12 from falling.

[0073] 2), When the winding machine needs a new bobbin 12, the conveying motor 97 is started, which drives the lead screw 96 to rotate. The rotation of the lead screw 96 drives the slider 94 to move along the guide rail 93. The movement of the slider 94 is linked to the connection seat 95, causing the connection seat 95 to extend. At this time, the mandrel 991 of the cylinder I99 retracts, and the bottommost bobbin 12 falls onto the connection seat 95, but is still restricted by the hopper 98.

[0074] 3), The conveying motor 97 continuously drives the connection seat 95. When the bobbin positioning groove 951 of the connection seat 95 passes by the bottommost bobbin 12, this bobbin 12 is loaded into the bobbin positioning groove 951 until one bobbin 12 is loaded into each of the 4 bobbin positioning grooves 951.

[0075] 4), After the winding machine grabs the 4 bobbins 12 on the connection seat 95, the cylinder II15 retracts, causing the bottom plate 92 to rotate downward by an angle, so that the bobbins 12 on the connection seat 95 are separated from the connection seat 95, and the bobbins 12 will not be caught when the connection seat 95 retracts. At the same time, the conveying motor 97 rotates in the reverse direction to reset the connection seat 95. After the connection seat 95 is reset, the cylinder II15 is also reset, and the bottom plate 92 is kept in a horizontal state by the compression spring 14.

[0076] The winding method of the full-automatic winding machine of the present utility model is as follows:

[0077] 1), The yarn 11 is unwound from the large roll of raw yarn 10 and passes through the tensioner 21, the yarn passing roller 22, the yarn detector 23 and the yarn guiding mechanism 4 in sequence to reach the bobbin 12; at this time, the active winding mechanism 3 is started and drives the bobbin 12 to rotate, and the yarn guiding mechanism 4 reciprocates to guide the yarn, so that the yarn 11 is continuously wound onto the bobbin 12 until the body of the bobbin 12 is covered with the yarn 11.

[0078] 2), The tube clamping mechanism 6 rises and grabs the bobbin 12, and the passive headstock mechanism 5 retracts to release the bobbin 12; then, the tube clamping mechanism 6 descends and rotates downward, making the bobbin 12 lean towards one side of the scissor mechanism 7.

[0079] 3), The tube feeding mechanism 9 is started, and it conveys a new bobbin 12 to between the active winding mechanism 3 and the passive headstock mechanism 5; then the passive headstock mechanism 5 extends, making the bobbin 12 abut between the active winding mechanism 3 and the passive headstock mechanism 5, and clamping the yarn 11 between the passive headstock mechanism 5 and the bobbin 12.

[0080] 4), the scissors mechanism 7 extends and starts to cut the yarn 11; the cut yarn 11 is still clamped by the passive head mechanism 5 and the yarn bobbin 12, and the scissors mechanism 7 resets; thereafter, the tube clamping mechanism 6 further rotates downward, releases the yarn bobbin 12 and then resets;

[0081] 5), the active winding mechanism 3 restarts and repeats the actions of steps 1) to 4), thereby realizing full-automatic continuous production.

[0082] The above specific embodiments are only preferred embodiments of the present creation, and are not intended to limit the present creation. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present creation shall be included within the protection scope of the present creation.
