TECHNICAL FIELD

[0001] The present application relates to the field of textile equipment, in particular to a silk doubling machine. BACKGROUND

[0002] The silk doubling machine is used for winding the multiple yarns on the bobbin after being combined into a strand, and cutting into a spindle according to a certain length of the yarn. In the prior art, the cutting is directly performed by scissors or heating after the winding is completed, the thread end on the bobbin is not fixed, and there is a risk of being scattered, and manual fixing is required subsequently. SUMMARY

[0003] The present application overcomes at least one of the above problems and provides a silk doubling machine.

[0004] The technical scheme adopted by the present application is as follows: A silk doubling machine comprises: a frame; a clamping and rotating mechanism arranged on the frame and used for clamping an empty bobbin and driving the bobbin to rotate, the bobbin comprising a rod part and plate parts located at both ends of the rod part; a thread arranging mechanism arranged on the frame and having a guide hole through which the strand passes, the thread arranging mechanism being used for driving the strand to reciprocate between the two plate parts of the bobbin of the clamping and rotating mechanism; a thread end pasting mechanism used for pasting the strand on the plate part through a pasting block after the winding of the bobbin of the clamping and rotating mechanism is completed; a cutting mechanism used for cutting the strand after the work of the thread end pasting mechanism is completed.

[0005] Compared with the prior art, the thread end pasting mechanism is added in the present application, the strand can be pasted on the plate part through the pasting block after the winding of the bobbin is completed, so that the thread end of the strand of the bobbin is still limited after the strand is cut by the cutting mechanism, and there is no risk of being scattered, and workers do not need to additionally fix it.

[0006] In one embodiment of the present application, the thread end pasting mechanism comprises: a first support seat fixed on the frame; a second support seat fixed on the frame; a rotating member having a body and an extension rod fixed at one end of the body, the body being rotatably installed on the first support seat; a switching motor used for driving the rotating member to rotate; a first guide wheel fixed on the body; a second guide wheel fixed at one end of the extension rod away from the body; a waste disc rotatably installed on the body; a winding motor used for driving the waste disc to rotate; The sticking block tray is rotatably installed on the second support base, and the sticking block tray comprises a tape and sticking blocks arranged on the tape at intervals. The tape is wound on the waste tray after sequentially passing through the first guide wheel and the second guide wheel. The sticking block is a sticking layer, and the sticking force between the sticking block and the tape is less than the sticking force between the sticking block and the plate portion. The rotating member has an initial working position and a sticking working position. When the rotating member is in the sticking working position, the extension rod is rotated to one side of the bobbin in the clamping rotating mechanism, and the sticking block on the tape is in contact with the upper end of the plate portion of the bobbin, so that the sticking block sticks the strand on the plate portion.

[0007] In one embodiment of the present application, the extension rod has an elastic protrusion between the extension rod and the tape. When the rotating member is in the sticking working position, the elastic protrusion is aligned with the upper end of the plate portion.

[0008] When the thread sticking mechanism is working, the winding motor rotates by a set angle. At this time, the sticking block corresponds to the elastic protrusion. The switching motor drives the rotating member to switch from the initial working position to the sticking working position, that is, the extension rod is rotated to one side of the bobbin in the clamping rotating mechanism, and the sticking block on the tape is in contact with the upper end of the plate portion of the bobbin, so that the sticking block sticks the strand on the plate portion. Because of the existence of the elastic protrusion, the sticking block can better contact and bear force with the strand and the plate portion.

[0009] In one embodiment of the present application, the thread sticking mechanism further comprises a limiting assembly. The limiting assembly comprises two limiting rods. The limiting rod has a straight portion and an arc-shaped guide portion. One end of the straight portion is fixed on the rack. The straight portion is located above the bobbin of the clamping rotating mechanism and is arranged along the axis direction of the bobbin. The arc-shaped guide portion is connected with the end of the straight portion away from the rack. The two limiting rods form a shape similar to a pair of eight characters.

[0010] The limiting assembly is used to limit the position of the strand, so that the strand has more contact with the plate portion, and the sticking block can stick the strand on the plate portion.

[0011] In one embodiment of the present application, the cutting mechanism comprises: A supporting plate is located directly below the bobbin of the clamping rotating mechanism. After the clamping rotating mechanism releases the bobbin, the supporting plate can receive the bobbin. A first telescopic element is used to drive the supporting plate to move up and down. A first movable rod is installed on the rack and can move horizontally. A heating wire is fixed on the end of the first movable rod. A first driving structure is used to drive the first movable rod to move, so that the heated heating wire is in contact with the strand above the bobbin, and the strand is cut off.

[0012] In one of the embodiments of the present application, the supporting plate has a limiting slot matched with the rod part of the cartridge. When the heating wire moves, the vertical distance between the upper end of the plate part of the cartridge and the heating wire is 0mm-10mm.

[0013] In this way, the cut strand is basically not exposed to the plate part.

[0014] In one of the embodiments of the present application, the wire arranging mechanism comprises: The second movable rod is installed on the frame and can move horizontally; The guide head is fixed on the second movable rod, and the guide hole is arranged on the guide head; The second driving structure is used to drive the second movable rod to move reciprocally.

[0015] The clamping and rotating mechanism is a conventional structure, and in one of the embodiments of the present application, the clamping and rotating mechanism comprises: The rotating shaft is rotatably installed on the frame, and the first elastic ejector pin is arranged on the rotating shaft; The rotating driving assembly is used to drive the rotating shaft to rotate; The third movable rod is installed on the frame and can move horizontally; The ejector pin seat assembly is fixed on the movable rod, and the ejector pin seat assembly comprises the second elastic ejector pin which can rotate and is aligned with the first elastic ejector pin; The third driving structure is used to drive the third movable rod to move, so that the cartridge is clamped between the rotating shaft and the ejector pin seat assembly.

[0016] In one of the embodiments of the present application, the feeding mechanism comprises: The inclined track is used to sequentially place a plurality of cartridges; The feeding seat is slidably installed on the frame, and the feeding seat is located below the inclined track, and the feeding seat has the positioning slot for receiving the cartridge from the inclined track; The fourth driving structure is used to drive the feeding seat to move, so that the cartridge on the positioning slot is located between the rotating shaft and the ejector pin seat assembly.

[0017] In one of the embodiments of the present application, the feeding seat rotatably has the positioning block, the positioning slot is arranged on the positioning block, one end of the tension spring is fixed to the feeding seat, and the other end of the tension spring is fixed to the positioning block, the positioning block has the horizontal working position and the inclined working position, and the tension spring is used to reset the positioning block to the horizontal working position after the positioning block is rotated by external force.

[0018] When the material cylinder on the positioning groove is clamped by the clamping and rotating mechanism, if the feeding seat moves directly, the presence of the positioning groove will cause interference. In this application, the positioning groove is set on the positioning block that is rotatably mounted on the feeding seat, so that the positioning block can rotate during the translation, which does not affect the reset movement of the feeding seat. Moreover, due to the presence of the tension spring, the positioning block can automatically reset when the positioning groove is disengaged from the material cylinder.

[0019] The drive structures in this application can adopt various existing drive structures, such as electric actuators, cylinders, etc. The first telescopic element in this application can be an electric actuator. The rotary drive assembly in this application can have various structural forms, including but not limited to direct drive by a motor or drive by a transmission shaft.

[0020] The beneficial effects of this invention are: compared with the existing twinning machine, this application adds a thread end pasting mechanism, which can paste the strands onto the plate by pasting blocks after the material barrel is wound. In this way, after the cutting mechanism cuts the strands, the ends of the strands in the material barrel are still restricted, so there is no need to worry about the risk of them coming apart, and no need for workers to fix them separately.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of 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.

They are used only for the convenience of describing this application and for 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 limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] The present invention will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1 to 15 As shown, a spinning machine includes: Rack 1; The clamping and rotating mechanism 2 is mounted on the frame 1 and is used to clamp the empty material cylinder 3 and drive the material cylinder 3 to rotate. The material cylinder 3 includes a rod 31 and plate parts 32 located at both ends of the rod 31. The wire laying mechanism 4 is mounted on the frame 1 and has a guide hole 421 for the strands to pass through. The wire laying mechanism 4 is used to drive the strands to reciprocate between the two plates 32 of the barrel 3 of the clamping and rotating mechanism 2. The wire end pasting mechanism 5 is used to paste the strands of wire onto the plate part 32 by pasting block 582 after the material cylinder 3 of the clamping and rotating mechanism 2 has been wound. The cutting mechanism 6 is used to cut the strand after the wire head pasting mechanism 5 has finished working.

[0028] Compared with the existing wire twisting machine, this application adds a wire end pasting mechanism 5, which can paste the strands onto the plate 32 by pasting block 582 after the material cylinder 3 is wound. In this way, after the cutting mechanism 6 cuts the strands, the ends of the strands in the material cylinder 3 are still restricted, so there is no need to worry about the risk of them coming apart, and no need for workers to fix them.

[0029] like Figures 9 to 12 As shown, in this embodiment, the thread-attaching mechanism 5 includes: The first support base 51 is fixed on the frame 1; The second support base 52 is fixed on the frame 1; The rotating component 53 has a body 531 and an extension rod 532 fixed at one end to the body 531. The body 531 is rotatably mounted on the first support seat 51. Switch motor 54 to drive rotating component 53 to rotate; The first guide wheel 551 is fixed on the main body 531; The second guide wheel 552 is fixed to the end of the extension rod 532 away from the main body 531; Waste tray 56 is rotatably mounted on body 531; The winding motor 57 is used to drive the waste tray 56 to rotate; The adhesive block tray 58 is rotatably mounted on the second support base 52. The adhesive block tray 58 includes a material strip 581 and adhesive blocks 582 spaced apart on the material strip 581. After the material strip 581 passes around the first guide wheel 551 and the second guide wheel 552 in sequence, it is wound around the waste tray 56. The adhesive blocks 582 are adhesive layers. The adhesive force between the adhesive blocks 582 and the material strip 581 is less than the adhesive force between the adhesive blocks 582 and the plate portion 32. The rotating member 53 has an initial working position and a pasting working position. When the rotating member 53 is in the pasting working position, the extension rod 532 rotates toward the material cylinder 3 in the clamping and rotating mechanism 2, and the pasting block 582 on the material strip 581 contacts the upper end of the plate portion 32 of the material cylinder 3, so that the pasting block 582 pastes the strands of wire onto the plate portion 32.

[0030] like Figure 10 and 12 As shown, in this embodiment, the extension rod 532 has an elastic protrusion 533, which is located between the extension rod 532 and the strip 581. When the rotating member 53 is in the pasting position, the elastic protrusion 533 is aligned with the upper end of the plate portion 32.

[0031] When the thread-end pasting mechanism 5 is working, the take-up motor 57 rotates at a set angle. At this time, the pasting block 582 corresponds to the elastic protrusion 533. The switching motor 54 drives the rotating component 53 to switch from the initial working position to the pasting working position. That is, the extension rod 532 rotates towards the material cylinder 3 in the clamping and rotating mechanism 2, and the pasting block 582 on the material strip 581 contacts the upper end of the plate portion 32 of the material cylinder 3, so that the pasting block 582 pastes the strands of thread onto the plate portion 32. Because of the presence of the elastic protrusion 533, the pasting block 582 can better contact and bear force with the strands of thread and the plate portion 32.

[0032] like Figure 7 , 8 As shown in Figure 12, in this embodiment, the wire end pasting mechanism 5 further includes a limiting component, which includes two limiting rods 59. Each limiting rod 59 has a straight portion 591 and an arc-shaped guide portion 592. One end of the straight portion 591 is fixed on the frame 1. The straight portion 591 is located above the material cylinder 3 of the clamping and rotating mechanism 2 and is arranged along the axial direction of the material cylinder 3. The arc-shaped guide portion 592 is connected to the end of the straight portion 591 away from the frame 1. The two limiting rods 59 form a figure-eight-shaped structure.

[0033] The limiting component is used to restrict the position of the strand, so that the strand has more contact with the plate 32, making it easier for the adhesive block 582 to attach the strand to the plate 32.

[0034] like Figure 13 and 14 As shown, in this embodiment, the cutting-off mechanism 6 includes: The pallet 61 is located directly below the material cylinder 3 of the clamping and rotating mechanism 2, and can receive the material cylinder 3 after the clamping and rotating mechanism 2 releases the material cylinder 3; The first telescopic element 62 is used to drive the tray 61 to move up and down; The first movable rod 63 is mounted on the frame 1 and can move horizontally; Heating wire 64 is fixed to the end of the first movable rod 63; The first driving structure (not shown in the figure) is used to drive the first movable rod 63 to move, so that the heated heating wire 64 contacts the strand above the material cylinder 3 and cuts the strand.

[0035] like Figure 14 As shown, in this embodiment, the support plate 61 has a limiting groove 611 that mates with the rod portion 31 of the barrel 3; when the heating wire 64 moves, the vertical distance between the upper end of the plate portion 32 of the barrel 3 and the heating wire 64 is 0mm to 10mm. This arrangement ensures that the cut strands of wire are basically not exposed on the plate portion 32.

[0036] like Figures 7 to 8 As shown, in this embodiment, the wiring mechanism 4 includes: The second movable rod 41 is mounted on the frame 1 and can move horizontally. The guide head 42 is fixed on the second movable rod 41, and the guide head 42 has a guide hole 421. The second drive structure (not shown in the figure) is used to drive the second movable rod 41 to reciprocate.

[0037] The clamping and rotating mechanism 2 is an existing structure. In this embodiment, the clamping and rotating mechanism 2 includes: A rotating shaft 21 is rotatably mounted on the frame 1, and a first elastic ejector pin 211 is provided on the rotating shaft 21. A rotary drive assembly (not shown in the figure) is used to drive the rotary shaft 21 to rotate; The third movable rod 22 is mounted on the frame 1 and can move horizontally; The ejector pin assembly 23 is fixed on the movable rod. The ejector pin assembly 23 includes a rotatable second elastic ejector pin (not shown in the figure), which is aligned with the first elastic ejector pin 211. The third drive structure (not shown in the figure) is used to drive the third moving rod to move, so that the material cylinder 3 is clamped between the rotating shaft 21 and the ejector pin assembly 23.

[0038] like Figures 1 to 6 As shown, in this embodiment, a feeding mechanism 7 is also included, which includes: Inclined track 71 is used to place multiple material cylinders 3 in sequence; The feeding seat 72 is slidably mounted on the frame 1. The feeding seat 72 is located below the inclined rail 71. The feeding seat 72 has a positioning groove 7211 for receiving the material cylinder 3 from the inclined rail 71. The fourth drive structure (not shown in the figure) is used to drive the feed seat 72 to move, so that the material cylinder 3 on the positioning groove 7211 is located between the rotating shaft 21 and the ejector pin assembly 23.

[0039] like Figure 2 As shown, in this embodiment, a tension spring 722 is also included. A positioning block 721 is rotatably mounted on the feeding seat 72. A positioning groove 7211 is disposed on the positioning block 721. One end of the tension spring 722 is fixed to the feeding seat 72, and the other end is fixed to the positioning block 721. The positioning block 721 has a horizontal working position and an inclined working position. The tension spring 722 is used to reset the positioning block 721 to the horizontal working position after the positioning block 721 is rotated by an external force.

[0040] When the material cylinder 3 on the positioning groove 7211 is clamped by the clamping and rotating mechanism 2, if the feeding seat 72 moves directly, the presence of the positioning groove 7211 will cause interference. In this application, the positioning groove 7211 is set on the positioning block 721 rotatably mounted on the feeding seat 72, so that the positioning block 721 can rotate during the translation, which does not affect the reset movement of the feeding seat 72. Moreover, due to the presence of the tension spring 722, the positioning block 721 can automatically reset after the positioning groove 7211 is disengaged from the material cylinder 3.

[0041] The drive structures in this application can adopt various existing drive structures, such as electric actuators, cylinders, etc. The first telescopic element 62 in this application can be an electric actuator. The rotary drive assembly in this application can have various structural forms, including but not limited to direct drive by a motor or drive by a transmission shaft.

[0042] The above description is merely a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural transformations made based on the description and drawings of the present invention, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present invention.
