Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textile equipment, in particular to a spinning winding device for preventing yarn interference between bobbins. Background Art
[0002] The winding device is an important component in textile machinery. The winding device can form a silk tube with a certain volume on the bobbin after processing of the processed yarn, so as to facilitate the subsequent dyeing, transportation and storage.
[0003] The winding device includes a base and a bobbin holder. The bobbin holder is rotatably connected to the base through its rotating shaft. The bobbin holder is symmetrically installed with two bobbins. Driven by the rotating shaft, the silk bobbin on one bobbin is wound up, that is, it rotates downward to the tray position, and the other bobbin rotates upward and contacts the black roller (the black roller applies contact pressure to the bobbin to meet customers' different needs for yarn density or hardness wound on the bobbin).
[0004] When the two bobbins are completed alternating up and down, the wire catching frame moves between the two bobbins to cut the silk thread. After the silk thread is cut, the lower bobbin is still in the process of high-speed rotation and gradually slows down. In this way, the silk thread end on the lower bobbin is easily thrown out and entangled on the upper bobbin, causing interference between the yarns between the bobbins. Utility Model Content
[0005] In view of this, an embodiment of the utility model provides a spinning winding device for preventing yarn interference between bobbins, the main purpose of which is to prevent the yarn of the lower bobbin from being thrown out and winding around the upper bobbin.
[0006] In order to achieve the above purpose, the utility model mainly provides the following technical solutions:
[0007] The embodiment of the utility model provides a spinning winding device for preventing yarn interference between bobbins, the device comprising: a base, a bobbin support and a flap mechanism;
[0008] The bobbin holder is rotatably connected to the base with its rotating shaft as the center, and a wire catching frame is arranged in a space on one side of the bobbin holder. The wire catching frame can move radially with respect to the bobbin holder and is used to cut the wire between the two bobbins of the bobbin holder;
[0009] The flap mechanism includes a cylinder, a guide sleeve and a flap, the cylinder and the guide sleeve are fixedly connected to the base in the space on the other side of the bobbin holder, the guide sleeve and the bobbin of the bobbin holder extend in the same direction, the piston rod of the cylinder is inserted into the guide sleeve, a spiral guide groove is provided on the upper side of the tube wall of the guide sleeve, one side of the flap is connected to the axial side of the piston rod through a connecting rod, and the connecting rod is slidably connected to the spiral guide groove.
[0010] The purpose of the utility model and the solution to its technical problems can also be further achieved by adopting the following technical measures.
[0011] Optionally, the other side of the flap is connected to a folding plate, and the folding plate is inclined toward the bobbin holder relative to the flap.
[0012] Optionally, a threaded blind hole is provided on the axial side of the piston rod, one end of the connecting rod is connected to the flap by a bolt, the other end of the connecting rod is fixedly connected to one end of a cylindrical pin, the cylindrical pin is slidably connected to the spiral guide groove, and the other end of the cylindrical pin is threadedly connected to the threaded blind hole.
[0013] Optionally, the number of the connecting rods and the number of the spiral guide grooves are at least two.
[0014] Optionally, when the flap is rotated close to the bobbin holder, the extension direction of the folding plate coincides with the extension direction of the wire catching frame.
[0015] By means of the above technical solution, the utility model has at least the following advantages:
[0016] When the silk thread winding of one bobbin is completed, the silk thread bobbin on one bobbin is driven by the rotating shaft to rotate downward to the tray position, and the other bobbin rotates upward and contacts the black roller, ready to restart the silk thread winding, and the wire catching frame extends to the position between the two bobbins of the bobbin holder. At the same time, the piston rod of the cylinder is extended, and the piston rod drives the connecting rod to spirally advance along the spiral guide groove, so that the connecting rod and the flap rotate radially at a certain angle relative to the guide sleeve, so that the other side of the flap is aligned with the wire catching frame, separating the space where the two bobbins are located.
[0017] At this time, the cutting knife on the wire catching frame cuts off the silk thread at the edge of the silk reel at the tray position. Even if the silk reel continues to rotate due to inertia, the silk thread is thrown out to a certain length relative to the silk reel radially. Since the two bobbins have been separated, the thrown out silk thread is blocked by the flap and will not touch the bobbin at the black roller upward, thus preventing the silk thread of the lower bobbin from interfering with the upper bobbin. The process of winding the yarn on the two bobbins is relatively independent.
[0018] When the wire tube at the tray stops its inertial rotation, the piston rod of the cylinder contracts, driving the connecting rod to move in the reverse spiral direction, the flap rotates away from the bobbin holder, and the wire catching frame retracts to prepare for the next rotation of the bobbin holder.
[0019] The device converts the reciprocating movement of the cylinder piston rod into the rotation of the flap through the cooperation of the cylinder and the guide sleeve structure, thereby isolating the two bobbins from each other and completely preventing the yarn of the lower bobbin from being thrown out and entangled on the upper bobbin.

DETAILED DESCRIPTION
[0026] In order to further explain the technical means and effects adopted by the utility model to achieve the predetermined utility model purpose, the specific implementation methods, structures, features and effects of the utility model application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.
[0027] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0028] like Figures 1 to 5 As shown, an embodiment of the utility model provides a spinning winding device for preventing yarn interference between bobbins, which includes: a base 1, a bobbin 14 support and a flap 6 mechanism;
[0029] The bobbin 14 support is rotatably connected to the base 1 with its rotating shaft 2 as the center. A wire catching frame 3 is arranged on one side of the bobbin 14 support. The wire catching frame 3 can move radially relative to the bobbin 14 support to cut the wire between the two bobbins 14 of the bobbin 14 support.
[0030] The flap 6 mechanism includes a cylinder 4, a guide sleeve 5 and a flap 6, the cylinder 4 and the guide sleeve 5 are fixedly connected to the base 1 on the other side of the space of the bobbin 14 bracket, the guide sleeve 5 and the bobbin 14 of the bobbin 14 bracket extend in the same direction, the piston rod 7 of the cylinder 4 is inserted into the guide sleeve 5, and a spiral guide groove 8 is provided on the upper side of the tube wall of the guide sleeve 5, one side of the flap 6 is connected to the axial side of the piston rod 7 through a connecting rod 9, and the connecting rod 9 is slidably connected to the spiral guide groove 8.
[0031] The working process of the spinning winding device to prevent yarn interference between bobbins is as follows:
[0032] When the silk winding of the silk reel 12 of a bobbin 14 is completed, the silk reel 12 on one bobbin 14 is driven by the rotating shaft 2 to rotate downward to the position of the tray 15, and the other bobbin 14 rotates upward and contacts the black roller 16, ready to restart the silk winding, and the wire catching frame 3 extends to the position between the two bobbins 14 of the bobbin 14 bracket, and at the same time, the piston rod 7 of the cylinder 4 is extended, and the piston rod 7 drives the connecting rod 9 to spirally advance along the spiral guide groove 8, so that the connecting rod 9 and the flap 6 are radially rotated at a certain angle relative to the guide sleeve 5, so that the other side of the flap 6 is aligned with the wire catching frame 3, separating the space where the two bobbins 14 are located.
[0033] At this time, the cutting knife 13 on the wire catching frame 3 cuts off the silk thread at the edge of the silk reel 12 at the tray 15. Even if the silk reel 12 continues to rotate due to inertia, the silk thread is thrown out radially to a certain length relative to the silk reel 12. Since the two bobbins 14 have been separated, the thrown out silk thread is blocked by the flap 6 and will not touch the bobbin 14 at the black roller 16 upward, thereby preventing the silk thread of the silk reel 12 on the lower bobbin 14 from interfering with the upper bobbin 14. The process of winding the yarn on the two bobbins 14 is relatively independent.
[0034] When the wire tube 12 at the tray 15 stops its inertial rotation, the piston rod 7 of the cylinder 4 contracts, driving the connecting rod 9 to move in the reverse spiral direction, the flap 6 rotates away from the bobbin 14 bracket, and the wire catching frame 3 retracts to prepare for the next rotation of the bobbin 14 bracket.
[0035] In the technical solution of the utility model, the device converts the reciprocating movement of the piston rod 7 of the cylinder 4 into the rotation of the flap 6 through the cooperation of the cylinder 4 and the guide sleeve 5 structure, thereby isolating the two bobbins 14 from each other and completely preventing the yarn of the lower bobbin 14 from being thrown out and entangled on the upper bobbin 14.
[0036] Specifically, the rotating shaft 2 of the bobbin 14 support is coaxially connected to the output shaft of the programmable motor, thereby realizing the switching of the positions of the two bobbins 14 .
[0037] Specifically, the radial angle of the guide sleeve 5 occupied by the spiral guide groove 8 is 90°. During the reciprocating movement of the piston rod 7 of the cylinder 4 along the guide sleeve 5, due to the constraint of the spiral guide groove 8 on the connecting rod 9, the piston rod 7 undergoes a 90° radial rotation, thereby realizing a 90° flipping of the flap 6.
[0038] like Figures 1 to 5 As shown, in a specific embodiment, the other side of the flap 6 is connected to the folding plate 10, and the folding plate 10 is inclined relative to the flap 6 toward the bobbin 14 support.
[0039] In this embodiment, specifically, when the flap 6 flips to the proximal end of the bobbin 14 bracket, the folding plate 10 tilts toward the bobbin 14 bracket relative to the flap 6, and the flap 6 and the folding plate 10 cooperate with each other. The center of curvature of the curved surface formed by the flap 6 and the folding plate 10 is close to the bobbin 14 at the tray 15, so that the inner contour of the curved surface matches the contour of the wire drum 12, and the silk thread thrown out by the rotation of the wire drum 12 is blocked by the curved surface, further limiting the throwing range of the silk thread.
[0040] In a specific embodiment, a threaded blind hole is provided on the axial side of the piston rod 7, one end of the connecting rod 9 is connected to the flap 6 by a bolt, the other end of the connecting rod 9 is fixedly connected to one end of a cylindrical pin 11, the cylindrical pin 11 is slidably connected to the spiral guide groove 8, and the other end of the cylindrical pin 11 is threadedly connected to the threaded blind hole.
[0041] In the present embodiment, specifically, a first through hole is provided on one end side of the connecting rod 9, and a second through hole is provided on the flap 6. The bolt passes through the first through hole and the second through hole in sequence and is connected to the nut to realize the fixed connection between the connecting rod 9 and the flap 6. The axial side surface of the cylindrical pin 11 is in sliding contact with the inner wall of the spiral guide groove 8, and the other end of the cylindrical pin 11 is threadedly connected to the threaded blind hole for easy disassembly.
[0042] like Figure 1 As shown, in a specific embodiment, the number of the engagement rods 9 and the number of the spiral guide grooves 8 are at least two.
[0043] In this embodiment, specifically, the number of the spiral guide grooves 8 and the number of the connecting rods 9 are at least two, and each connecting rod 9 is slidably connected to one of the spiral guide grooves 8 .
[0044] like Figure 4 As shown, in a specific embodiment, when the flap 6 rotates close to the bobbin 14 support, the extension direction of the folding plate 10 coincides with the extension direction of the wire catching frame 3 .
[0045] In the present embodiment, specifically, when the piston rod 7 of the cylinder 4 drives the flap 6 to rotate close to the bobbin 14 bracket, the extension direction of the folding plate 10 coincides with the extension direction of the wire catching frame 3, and at the same time the wire catching frame 3 extends between the two bobbins 14, the wire catching frame 3 and the folding plate 10 are close to each other, and the wire catching frame 3 and the folding plate 10 are located in the same plane at this time, which can better cover the wire reel 12 at the tray 15 to form an isolation space, and after the cutting knife 13 of the wire catching frame 3 cuts off the silk thread, the silk thread at the edge of the silk reel 12 is centrifugally thrown out and will not leave the isolation space, that is, the silk thread of the lower silk reel 12 will not contact the upper bobbin 14.
[0046] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
