Description

Technical Field

[0001] This invention belongs to the technical field of yarn splicing devices, specifically relating to an automatic yarn splicing device for a winding machine. Background Technology

[0002] Our company uses a winding machine in the production process of fiber yarn winding molds. After the fiber yarn comes out of the yarn rack, it is dipped in the glue tank, passes through the winding nozzle, and then the clamps on the winding machine drive the mold to rotate, so that the fiber yarn is wound on the mold. After winding, the fiber yarn on the mold is cut by a yarn cutting device. Then, the molds at each station of the winding machine are removed and replaced with new molds. The yarn cutting device automatically connects the molds. Patent application number "202110753432.X" discloses a method and device for automatic yarn cutting of wound yarn. Through a first pressure roller, a yarn clamping rod, a second pressure roller, and a cutter driven by a cylinder, the yarn splicing and cutting operations of the winding mold are automatically realized. Compared with the existing manual yarn cutting operation, it greatly improves the working efficiency of the winding yarn process and realizes automated yarn splicing and cutting operations. The existing technology has the following shortcomings:

[0003] 1. The existing yarn splicing device is installed on the winding nozzle, and the winding nozzle and the existing yarn splicing device share a power unit. The existing yarn splicing device is heavy, and with each additional station on the winding machine, an additional yarn splicing device is added to the winding nozzle, further increasing the weight. The winding nozzle needs to move rapidly left and right to follow the rotation of the mold. Due to the increased weight, the winding nozzle cannot withstand excessive speed, thereby reducing the rotation speed of the mold on the winding machine station. This changes the time required to wind the fiber yarn from 400 minutes to 500-600 minutes, greatly reducing production efficiency.

[0004] 2. The existing yarn-splitting device is located directly above the mold, cutting the fiber yarn from above. This device is positioned between the molds at the upper and lower stations of the winding machine. This necessitates increasing the center-to-center distance between each station. For example, if the original distance between the upper and lower stations was 0.6 meters, the height of a winding machine with 6 stations would be 3.6 meters. Adding the yarn-splitting device increases the distance by 0.3 meters per station, totaling 1.8 meters for 6 stations. The total height of the winding machine then becomes 5.4 meters. This increases production costs and size, especially the height. According to customer feedback, it even exceeds the factory's height, making installation and use impossible. Workers must climb to observe the machine's operation and resolve mold and yarn issues during winding, which is both dangerous and cumbersome. Since customers are moving towards intelligent and automated production, the excessive height of the equipment severely hinders the subsequent automatic mold-mounting and unmounting operation of the robotic arm, significantly increasing the manufacturing cost and difficulty of the automated production line.

[0005] 3. Existing yarn splicing devices require each one to be installed on the winding nozzle, which is inconvenient to transport and unload, and also requires workers to install, increasing installation costs. Summary of the Invention

[0006] Purpose of the invention: The purpose of this invention is to provide an automatic yarn cutting device that prevents the low yarn winding efficiency of winding machines, reduces the production cost of winding machines, and is suitable for many enterprises with low factory heights and requirements for automated production. It reduces the risk of workers having to climb high to check the work station, and the yarn cutting device is installed on the winding machine, making installation convenient, reducing installation costs and installation time.

[0007] An automatic yarn splicing device for a winding machine includes a winding machine, a clamp on the winding machine, a mold on the clamp, a winding nozzle on the winding machine, and a yarn splicing device on the winding machine. The device is characterized in that the winding machine has a first cylinder, the yarn splicing device includes a splicing mechanism and a support, the first cylinder is connected to the support, the support has the splicing mechanism located in front of the mold, the winding machine has a first guide rail, the support has a first slider slidably connected to the first guide rail, the splicing mechanism includes a support plate, the support plate has a second guide rail, the support has a second slider slidably connected to the second guide rail, the support has a second cylinder connected to the support plate, and the support plate includes a pushing mechanism, a yarn receiving mechanism, and a yarn cutting mechanism.

[0008] The clamps on the winding machine drive the mold to rotate. After the fiber yarn is impregnated in the glue tank, it passes through the winding nozzle. The winding nozzle moves back and forth on the winding machine, so that the fiber yarn is wound on the mold. The support is equipped with a shearing mechanism with multiple stations. Cylinder 1 pushes the support, and slider 1 slides on guide rail 1, so that the support drives the shearing mechanism to move back and forth. Cylinder 2 pushes the support plate, and guide rail 2 moves on slider 2, so that the support plate moves back and forth on the support.

[0009] Furthermore, the pushing mechanism includes a cylinder three, one end of which is fixed to a support plate, and a flattening roller frame is provided at one end of the cylinder three. A guide rail three is provided on the inner side of the support plate, and a slider three is provided on the flattening roller frame. The guide rail three and the slider three are slidably connected.

[0010] Cylinder three pushes the leveling roller frame, and slider three slides on guide rail three, causing the leveling roller frame to move back and forth on the support plate.

[0011] Furthermore, the leveling roller frame is equipped with a cylinder four, the cylinder four is equipped with a leveling roller bracket, the leveling roller bracket is equipped with an upper pressure roller, the leveling roller bracket is rotatably connected to the leveling roller frame via a support shaft, and the leveling roller frame is equipped with a limiting shaft.

[0012] The cylinder pushes the flattening roller bracket to rotate on the flattening roller frame, and the limit shaft limits the flattening roller bracket to keep the upper pressure roller moving to the highest point and level with the horizontal plane.

[0013] Furthermore, the yarn splicing mechanism includes a cylinder five, and a cylinder shaft support is provided on the support plate. The cylinder five is rotatably connected to the cylinder shaft support through a cylinder connecting shaft. A large pressure roller is provided on the support plate, and a small pressure roller support is provided on the shaft of the large pressure roller. A small pressure roller is provided on the small pressure roller support, and the small pressure roller support is rotatably connected to the cylinder five through a pin.

[0014] Cylinder five pushes the small pressure roller bracket to rotate on the shaft of the large pressure roller, and the small pressure roller rotates along with the small pressure roller bracket.

[0015] Furthermore, the support plate is provided with a bearing seat, the bearing seat is provided with a rotating shaft, the rotating shaft is provided with a clamping bracket, the inner side of the support plate is provided with a cylinder six, the cylinder six is ​​connected to the clamping bracket, and the clamping bracket is provided with a clamping plate one.

[0016] The cylinder pushes the clamping bracket, the rotating shaft rotates in the bearing seat, and the clamping plate rotates in one circle.

[0017] Furthermore, the clamping plate is L-shaped.

[0018] The clamping plate simultaneously lifts the fiber yarn from the upper and right sides.

[0019] Furthermore, the yarn shearing mechanism includes a cylinder support, which is fixed on a bracket plate. A cylinder seven is provided on the cylinder support, and a cutter is provided on the cylinder seven.

[0020] Cylinder seven drives the cutter to move up and down.

[0021] Furthermore, the cylinder support is provided with a clamping plate two.

[0022] When the clamping plate lifts the limiting yarn, its right side clamps the lifted fiber yarn with the clamping plate.

[0023] Furthermore, the upper pressure roller, the large pressure roller, and the small pressure roller are all made of rubber.

[0024] Maximum protection and limit yarn to prevent breakage of fiber yarn.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] The yarn splicing device is no longer installed on the winding nozzle, but is independently mounted on the winding machine. It does not move with the movement of the winding nozzle. When the fiber yarn needs to be cut after the mold has wound it, cylinder one pushes the bracket to the left, so that the splicing mechanism is directly in front of the mold. Then, through the pushing mechanism, yarn splicing mechanism, and yarn cutting mechanism, the yarn lifting, clamping, pressing, and cutting are completed. Then, cylinder two pushes the bracket plate closer to the mold to complete the yarn splicing. This invention is independently installed, which does not add weight to the winding nozzle and prevents low yarn winding efficiency of the winding machine. At the same time, each splicing mechanism on the bracket is located directly in front of the corresponding mold, without changing the vertical distance between the workstations and the molds on the winding machine, thus reducing the production cost of the winding machine. It is suitable for many enterprises with low factory heights and requirements for automated production. It reduces the risk of workers climbing to check the workstations. Moreover, the entire yarn splicing device is installed on the winding machine, which is convenient for installation, reduces installation costs, and reduces installation time.

A guide rail 15 is provided on the inner side of the support plate 9, and a slider 16 is provided on the flattening roller frame 14. The guide rail 15 and the slider 16 are slidably connected.

[0043] Furthermore, the leveling roller frame 14 is provided with a cylinder 4 17, the cylinder 4 17 is provided with a leveling roller bracket 18, the leveling roller bracket 18 is provided with an upper pressure roller 19, the leveling roller bracket 18 is rotatably connected to the leveling roller frame 14 through a support shaft 20, and the leveling roller frame 14 is provided with a limiting shaft 21.

[0044] Furthermore, the yarn splicing mechanism includes a cylinder 22, and a cylinder shaft support 23 is provided on the support plate 9. The cylinder 22 is rotatably connected to the cylinder shaft support 23 through a cylinder connecting shaft 24. A large pressure roller 25 is provided on the support plate 9. A small pressure roller support 26 is provided on the shaft of the large pressure roller 25. A small pressure roller 27 is provided on the small pressure roller support 26. The small pressure roller support 26 is rotatably connected to the cylinder 22 through a pin.

[0045] Furthermore, the support plate 9 is provided with a bearing seat 28, the bearing seat 28 is provided with a rotating shaft 29, the rotating shaft 29 is provided with a clamping bracket 30, the support plate 9 is provided with a cylinder 31, the cylinder 31 is connected to the clamping bracket 30, and the clamping bracket 30 is provided with a clamping plate 32.

[0046] Furthermore, the clamping plate 32 is L-shaped.

[0047] Furthermore, the yarn cutting mechanism includes a cylinder support 33, which is fixed on the support plate 9. A cylinder 34 is provided on the cylinder support 33, and a cutter 35 is provided on the cylinder 34.

[0048] Furthermore, the cylinder support 33 is provided with a clamping plate 36.

[0049] Furthermore, the upper pressure roller 19, the large pressure roller 25, and the small pressure roller 27 are all made of rubber.

[0050] The method of using this invention is as follows:

[0051] like Figure 1 As shown:

[0052] Cylinder 5 pushes bracket 6 to move to the left, and slider 8 moves on guide rail 7, so that bracket plate 9 is located in front of mold 3.

[0053] like Figure 2-4 As shown:

[0054] Yarn lifting and clamping: The fiber yarn on the mold 3 is located between the clamping plate 32 and the upper pressure roller 19. The cylinder 31 pushes the clamping plate bracket 30, and the rotating shaft 29 rotates in the bearing seat 28. The upper and right parts of the clamping plate 32 lift the fiber yarn until the right part of the clamping plate 32 and the clamping plate 36 clamp the fiber yarn. At the same time, the fiber yarn also abuts against the large pressure roller 25.

[0055] like Figure 5 As shown:

[0056] Yarn pressing: Cylinder 3 13 pushes the flattening roller frame 14, slider 3 16 slides on guide rail 3 15, flattening roller frame 14 drives flattening roller support 18 and upper pressure roller 19 to move closer to mold 3, cylinder 4 17 pushes flattening roller support 18 down, so that upper pressure roller 19 presses the fiber yarn on mold 3, while the glue groove releases a section of zero-tension fiber yarn to prepare for subsequent yarn cutting and splicing.

[0057] Yarn cutting: Cylinder 7 34 drives the cutter 35 to cut down quickly, cutting the fiber yarn on clamping plate 1 32. One end of the fiber yarn on the mold 3 is broken off, and the fiber yarn that comes out from the winding nozzle 4 is still clamped between the right side of clamping plate 1 32 and clamping plate 2 36. At this time, the clamp 2 rotates, and with the help of the upper pressure roller 19, the broken fiber yarn is wound up, so that the exposed yarn end is wrapped around the mold 3. Cylinder 4 17 pushes the flattening roller bracket 18 back to its original position, the upper pressure roller 19 is disengaged from the mold 3, and cylinder 3 13 pulls the flattening roller bracket 14 back to its original position. Then, a new mold 3 without fiber yarn is replaced.

[0058] like Figure 3 and 6 As shown in -10:

[0059] Yarn splicing: Cylinder 212 pushes the support plate 9, and guide rail 210 slides on slider 21, causing the large pressure roller 25 to press against the new mold 3, with the fiber yarn sandwiched between the large pressure roller 25 and the mold 3. Cylinder 522 pushes the small pressure roller support 26 to rotate on the shaft of the large pressure roller 25, causing the small pressure roller 27 to press down and press against the broken end of the fiber yarn against the mold 3, causing the fiber yarn that was originally broken and whose end was sandwiched between the right side of clamping plate 1 32 and clamping plate 2 36 to detach and be pressed against the mold. On die 3, clamp 2 drives die 3 to rotate slightly in the opposite direction, causing the fiber yarn on die 3 to retract a short distance. This allows the detached fiber yarn to be flattened onto die 3 by the large pressure roller 25. Since the fiber yarn has adhesive, it will stick to die 3. Then, cylinder 5 22 drives the small pressure roller 27 back to its original position, and clamp 2 drives die 3 to rotate in the forward direction, causing the zero-tension fiber yarn to continuously wrap around die 3. After one rotation, cylinder 2 12 drives the support plate 9 back to its original position, and cylinder 1 5 drives the support 6 back to its original position. This ends the yarn splicing function, and the winding machine enters the subsequent normal winding state.

[0060] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present invention, and these improvements should also be considered within the scope of protection of the present invention.
