Description

Technical Field

[0001] The present application relates to the technical field of spinning equipment, and in particular to a bobbin support device and a processing technology for multi-color plied yarns. Background Art

[0002] When multiple single yarns are combined into one, it is necessary to support and fix the bobbins of the single yarns.

[0003] Currently, a bobbin support device includes a fixed frame, a guiding frame provided on the fixed frame, and a guiding ring fixed on the guiding frame; a tray is fixedly connected to the fixed frame, and a fixed rod is fixed on the tray. The bobbin is placed on the tray, and the fixed rod passes through the bobbin.

[0004] Since the fixed rod only passes through the bobbin, when the bobbin abuts against the tray, the bobbin will shake. When the bobbin shakes, the yarn dragged on the bobbin will be damaged, resulting in a decline in the production quality of subsequent products. Summary of the Invention

[0005] In order to ensure the quality of subsequent products, the present application provides a bobbin support device and a processing technology for multi-color plied yarns.

[0006] In a first aspect, a bobbin support device provided by the present application adopts the following technical solution: A bobbin support device includes a fixed frame, a guiding frame, and a guiding ring. The guiding frame is provided on the fixed frame, and the guiding ring is provided on the guiding frame. It further includes a bobbin connection mechanism. The bobbin connection mechanism includes a first fixing block, a supporting block, a fixed rod, and a pressing component. The first fixing block is provided on the fixed frame, the fixed rod is provided on the first fixing block, and the supporting block is provided on the fixed rod; the pressing component includes a first connecting ring, a second connecting ring, and elastic pressing blocks. Both the first connecting ring and the second connecting ring are provided on the fixed rod. There are multiple elastic pressing blocks. One end of the elastic pressing block is connected to the first connecting ring and the other end is connected to the second connecting ring; the fixed rod is located below the guiding ring.

[0007] By adopting the above technical solution, move the bobbin so that the fixed rod passes through the middle hole on the bobbin; when the bobbin abuts against the elastic pressing block, the elastic pressing block will deform; when the bobbin abuts against the supporting block, the force of the elastic pressing block restoring its elastic deformation will cause the elastic pressing block to press against the bobbin, thereby fixing the bobbin on the fixed rod; then wind the yarn on the bobbin out of the bobbin and pass it through the guiding ring above the fixed rod. In this way, when the yarn moves, the yarn only winds out of the bobbin and does not drive the bobbin to move; therefore, the provided bobbin connection mechanism can reduce the phenomenon that the bobbin moves when the yarn winds out of the bobbin, thereby ensuring the quality of subsequent products.

[0008] Optionally, an adjustment mechanism is provided on the fixed rod. The adjustment mechanism includes a first adjustment block, a second adjustment block, a third adjustment block, an adjustment lead screw, and a first spring. A first cavity is formed in the fixed rod, and a first through hole and a second through hole communicating with the first cavity are formed in the fixed rod. The first through hole and the second through hole are respectively located on both sides of the support block; the adjustment lead screw is rotatably arranged in the first cavity; one end of the first adjustment block is fixedly connected to the second connection ring, and the end of the first adjustment block away from the first connection ring passes through the first through hole and is located in the first cavity, and the first adjustment block is slidably connected to the first through hole; the adjustment lead screw passes through the first adjustment block and is threadedly connected to the first adjustment block; the second adjustment block is rotatably arranged on the fixed rod, one end of the third adjustment block is connected to the third adjustment block and the other end passes through the second through hole and is fixedly connected to the adjustment lead screw, and the third adjustment block is slidably connected to the second through hole; one end of the first spring is connected to the fixed rod and the other end is connected to the first adjustment block.

[0009] By adopting the above technical solution, when the fixed rod has not passed through the hole on the bobbin, rotate the second adjustment block. The third adjustment block on the second adjustment block drives the adjustment lead screw to rotate. The adjustment lead screw makes the first adjustment block slide in the first through hole. The first adjustment block drives the second connection ring to move away from the first connection ring. In this way, when moving the bobbin so that the bobbin abuts against the support block, the phenomenon that the elastic abutting block abuts against the bobbin and applies a force to the bobbin, which is not convenient for the bobbin to move, can be reduced; and when the bobbin abuts against the support block, rotate the second adjustment block to make the second connection ring move towards the first connection block, so that the elastic abutting block can better abut against the bobbin.

[0010] Optionally, a fixing mechanism is provided on the second adjustment block. The fixing mechanism includes a first adjusting block, a second adjusting block, a second fixing block, and a second spring. A second cavity is formed in the second adjustment block, and a third through hole and a fourth through hole communicating with the second cavity are formed in the second adjustment block. A clamping groove is formed in the fixed rod. The first adjusting block is slidably arranged in the second cavity. The second fixing block is arranged on the first adjusting block. The end of the second fixing block away from the first adjusting block can pass through the third through hole and be clamped with the clamping groove; the second adjusting block is connected to the first adjusting block, and the end of the second adjusting block away from the first adjusting block passes through the fourth through hole; one end of the second spring is connected to the second adjusting block and the other end is connected to the second adjustment block.

[0011] By adopting the above technical solution, before the bobbin touches the support block, the second fixing block is clamped with the card slot; after the bobbin is located on the support block, the operator squeezes the second adjusting block, and the second adjusting block drives the second fixing block to move through the first adjusting block, so that the second fixing block is separated from the card slot, and then the second adjusting block is rotated.

[0012] Optionally, an adjusting mechanism connected to the second adjusting block is provided on the second adjusting block. The adjusting mechanism includes a third adjusting block, an adjusting rod, a fourth adjusting block, a fifth adjusting block, a third spring, a sixth adjusting block, an adjusting component and a positioning component. The third adjusting block is slidably arranged on the support block, the adjusting rod is arranged on the third adjusting block, and the fourth adjusting block is arranged on the adjusting rod; a fifth through hole communicating with the second cavity is formed in the second adjusting block, and the fifth adjusting block is slidably arranged in the fifth through hole; one end of the third spring is connected to the fifth adjusting block and the other end is connected to the second adjusting block; the sixth adjusting block is slidably arranged in the second cavity, a sixth through hole is formed in the sixth adjusting block, the second adjusting block is slidably arranged in the sixth through hole, and the end of the second spring away from the connection with the second adjusting block is connected to the sixth adjusting block; the adjusting component is arranged on the second adjusting block, and both the fifth adjusting block and the sixth adjusting block are connected to the adjusting component; the positioning component is arranged on the support block and connected to the third adjusting block.

[0013] By adopting the above technical solution, when the fixed rod enters the hole in the middle of the bobbin and the bobbin does not touch the support block, the axis of the fixed rod may not coincide with the central axis of the bobbin. Therefore, when the bobbin is moved at this time, the bobbin will still touch the elastically tightened block that has been deformed and drive the elastically tightened block to move. However, due to the clamping connection between the second fixing block and the card slot, the position of the second connecting ring is fixed, and at this time, the bobbin may be worn or the tightening component may be damaged; therefore, before the bobbin touches the support block, the second fixing block is not clamped with the card slot, and the cross-section of the hole in the middle of the bobbin is larger than the maximum cross-section surrounded by the plurality of elastically tightened blocks. In this way, even before the bobbin touches the support block, when the bobbin touches one or several of the elastically tightened blocks, these elastically tightened blocks drive the second connecting ring to rotate, the first adjusting block on the second connecting block drives the adjusting screw rod to rotate, and the third adjusting block on the adjusting screw rod drives the second adjusting block to move; the bobbin touches the third adjusting block and drives the third adjusting block to move, the adjusting rod on the third adjusting block drives the fourth adjusting block to move, the fourth adjusting block pushes the fifth adjusting block to move, the fifth adjusting block drives the sixth adjusting block to move through the adjusting component, the sixth adjusting block drives the second adjusting block to move, and the first adjusting block on the second adjusting block drives the second fixing block to move closer to the fixed rod so that the second fixing block is still clamped with the card slot; then the third adjusting block is fixed on the support block by the positioning component.

[0014] Optionally, the adjusting assembly includes a first rack, an adjusting shaft, a first gear, a second gear and a second rack. The first rack is arranged on the fifth adjusting block; the adjusting shaft is rotatably arranged in the second cavity, the first gear and the second gear are both key-connected to the adjusting shaft, and the first gear meshes with the first rack; the second rack is arranged on the sixth adjusting block and meshes with the second gear.

[0015] By adopting the above technical solution, the first rack on the fifth adjusting block drives the first gear to rotate, the first gear drives the adjusting shaft to rotate, the second gear on the adjusting shaft will drive the second rack to move, and the second rack drives the sixth adjusting block to move.

[0016] Optionally, a first groove and a seventh through hole communicating with the first groove are formed in the support block. The third adjusting block is slidably arranged in the first groove, and the adjusting rod is slidably arranged in the seventh through hole; a second groove communicating with the first groove and an adjusting threaded hole communicating with the second groove are formed in the support block. The positioning assembly includes a positioning block and an adjusting bolt. The positioning block is slidably arranged in the second groove, and a positioning groove for clamping the positioning block is formed in the third adjusting block; the adjusting bolt is rotatably arranged on the positioning block, and one end of the adjusting bolt far away from the positioning block passes through the adjusting threaded hole and is in threaded connection with the adjusting threaded hole.

[0017] By adopting the above technical solution, when the wire reel abuts against the third adjusting block and drives the third adjusting block to move, the wire reel will enter the first groove. After the third adjusting block abuts against the bottom wall of the first groove, rotate the adjusting bolt, and the adjusting bolt drives the positioning block to move so that the positioning block is clamped with the positioning groove.

[0018] Optionally, a limiting groove is formed in the support block, and the wire reel can enter the limiting groove.

[0019] By adopting the above technical solution, the arranged limiting groove can position the wire reel, so that a plurality of elastic abutting blocks can better abut against the wire reel, thereby improving the stability.

[0020] Optionally, the first fixing block is slidably arranged on the fixing frame. A connecting assembly is arranged on the first fixing block. The connecting assembly includes a first fixing bolt, a second fixing bolt, a third fixing block and a slider. A sliding groove is formed in the fixing frame, and the slider is slidably arranged in the sliding groove; the third fixing block is fixedly arranged on the slider, and the first fixing bolt passes through the third fixing block and is in threaded connection with the fixing frame; a second fixing bolt is arranged on the first fixing block, and the second fixing bolt passes through the first fixing block and is in threaded connection with the third fixing block.

[0021] By adopting the above technical solution, as required, the slider slides in the chute, and the slider drives the third fixed block to move; after the position of the slider is determined, the first fixing bolt passes through the third fixed block and is bolted to the fixing frame to fix the positions of the slider and the third fixed block; then the first fixed block is abutted against the third fixed block, and the second fixing bolt passes through the first fixed block and the third fixed block to fix the first fixed block on the third fixed block.

[0041] The implementation principle of a bobbin support device in an embodiment of the present application is as follows: Move the bobbin so that one end of the fixing rod 23 away from the first fixing block 21 passes through the hole in the middle of the bobbin, and the bobbin first enters the limiting groove 221 of the support block 22. At this time, all the elastic abutting blocks 243 will not abut against the bobbin; then move the bobbin. The bobbin drives the third adjustment block 51 to move. The adjusting rod 52 on the third adjustment block 51 drives the fourth adjustment block 53 to move in a direction close to the second adjustment block 32. The fourth adjustment block 53 squeezes the fifth adjustment block 54 to make the fifth adjustment block 54 move. The first rack 571 on the fifth adjustment block 54 drives the first gear 573 to rotate. The first gear 573 drives the adjusting shaft 572 to rotate. The adjusting shaft 572 drives the second gear 574 to rotate. The second gear 574 drives the second rack 575 to move. The second rack 575 drives the sixth adjustment block 56 to move. The second spring 44 on the sixth adjustment block 56 drives the second adjustment block 42 to move. The second adjustment block 42 drives the first adjustment block 41 to move. The first adjustment block 41 drives the second fixing block 43 to move in a direction close to the fixing rod 23. When the third adjustment block 51 abuts against the bottom wall of the first groove, the second fixing block 43 is clamped with a clamping groove on the fixing rod 23. One end of the second adjustment block 42 away from the first adjustment block 41 passes through the fourth through-hole and is located outside the second adjustment block 32; at this time, the positioning block 581 is aligned with the positioning groove on the third adjustment block 51. Rotate the adjusting bolt 582, and the adjusting bolt 582 will drive the positioning block 581 to move in a direction close to the third adjustment block 51, so that the positioning block 581 is clamped with the positioning groove on the third adjustment block 51.

[0042] Then, the operator holds the second adjustment block 32, and the palm of the operator will squeeze the second adjustment block 42, causing the end of the second adjustment block 42 away from the first adjustment block 41 to be located within the fourth through hole of the second adjustment block 32, and the second spring 44 is deformed; the first adjustment block 41 on the second adjustment block 42 drives the second fixing block 43 to move, separating the second fixing block 43 from the card slot on the fixing rod 23; then, the second adjustment block 32 is rotated, the second adjustment block 32 drives the third adjustment block 33 to rotate, the third adjustment block 33 drives the adjustment screw rod 34 to rotate, and the adjustment screw rod 34 causes the first adjustment block 31 to slide within the first through hole 232 of the fixing rod 23. The first adjustment block 31 drives the second connection ring 242 to move towards the direction close to the first connection block, and the second connection ring 242 drives the elastic abutting block 243 to deform, and causes the elastic abutting block 243 to abut against the bobbin; after the elastic abutting block 243 better abuts against the bobbin, or when the third adjustment block 33 is rotated from one end of the second through hole to the other end of the second through hole, the second adjustment block 32 is released, and the force of the second spring 44 restoring elastic deformation drives the second adjustment block 42 to move. The first adjustment block 41 on the second adjustment block 42 drives the second fixing block 43 to move, causing the end of the second fixing block 43 away from the first adjustment block 41 to pass through the third through hole and be clamped with another card slot on the fixing rod 23; when the second adjustment block 32 is rotated, the fifth adjustment block 54 slides within the annular groove 531 of the fourth adjustment block 53.

[0043] After the bobbin is fixed on the fixing rod 23, the yarn on the bobbin is pulled out and passes through the guiding ring 13 on the guiding frame 12, and the yarn passing through the guiding ring 13 enters the doubling and twisting machine, combining multiple strands of yarn into one strand.

[0044] The embodiment of the present application also discloses a processing technology for multi-color plied yarns.

[0045] A processing technology for multi-color plied yarns includes the following steps: S1: Place the bobbins of yarns of different colors on the fixing rod 23, and cause the yarns of different colors on the bobbins to pass through the guiding ring 13 and then enter the doubling and twisting machine to form a preliminary color yarn bundle, and wind the yarn bundle on an empty bobbin; S2: Place the bobbin wound with the preliminary color yarn bundle on the fixing rod 23, and cause multiple preliminary color yarn bundles to pass through the guiding ring 13 and then enter the doubling and twisting machine to form a multi-color plied yarn.

[0046] For example, a total of five guiding rings 13 are provided on the guiding frame 12, and the five guiding rings 13 are located on the same straight line; the five guiding rings 13 are successively the first guiding ring 13, the second guiding ring 13, the third guiding ring 13, the fourth guiding ring 13, and the fifth guiding ring 13. The yarn passing through the first guiding ring 13, the second guiding ring 13, and the fifth guiding ring 13 is black, and the yarn passing through the third guiding ring 13 and the fourth guiding ring 13 is white. In this way, the five strands of yarn are twisted together in the doubling and twisting machine to form a preliminary color yarn bundle, and the preliminary color yarn bundles formed by the black yarn and the white yarn passing through the guiding rings 13 at different positions will be different.

[0047] Fix the bobbin of a preliminary color yarn bundle on the fixing rod 23, then pass the yarn of the preliminary color yarn bundle and a yarn of another color or a preliminary color yarn bundle through the guiding rings 13 at different positions and then enter the doubling and twisting machine for doubling operation, and finally form a multi-color doubled yarn.

[0048] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
