Description

Technical Field

[0001] This invention belongs to the field of yarn processing equipment, specifically relating to an automatic yarn start-up and cutting device and its application system. Background Technology

[0002] The yarn winding process is the pre-winding process in the spinning process. In the traditional dyeing process, the yarn is manually hung into the winding frame and wound. After winding, the excess yarn is cut off manually with scissors. This process is very labor-intensive, labor-intensive, and has low efficiency and output.

[0003] Existing yarn-forming mechanisms fix the yarn end to the spool at the start of winding, allowing the yarn to continue winding on the spool. This is typically done manually or semi-automatically, by binding the yarn end to the spool or clamping it to the spool clips. However, the main drawback of manual yarn-forming is its slow speed. The main drawback of semi-automatic mechanisms is inconsistent yarn-forming quality and uncontrollable yarn length. If the yarn end is too long, it will tangle and make unwinding difficult; if it is too short, it will easily fall off, resulting in failed yarn-forming. Therefore, existing yarn-forming mechanisms can no longer meet production needs. Summary of the Invention

[0004] Purpose of the invention: In order to overcome the shortcomings of the prior art, the present invention provides an automatic yarn feeding and cutting device and its application system.

[0005] Technical solution: An automatic wire feeding and cutting device, including a plug nut, a sliding pad, a sliding lever, a shape pressing plate, a main cutter, a secondary cutter, a telescopic cylinder, a base, a slider joint, a locking bolt, a wire pressing trigger, a countersunk bolt, a base plate, a fastening bolt, a return spring, a rotary actuator, a position sensor, a sensor bracket, a speed regulating valve, a swing arm, and a grooved wire pressing seat;

[0006] A rotary actuator is fixedly installed at the bottom of the swing arm. The bottom of the rotary actuator is provided with a mounting hole, which can be used to install it onto the equipment base plate or the position where the rotation function needs to be performed. Two speed regulating air valves are provided on the side of the rotary actuator. A sensor bracket is provided on the front face of the rotary actuator, and a position sensor is fixedly installed on the sensor bracket.

[0007] The swing arm has a small round hole on the side facing the rotary actuator containing a sensing magnet. When the swing arm rotates and swings with the output shaft of the rotary actuator, the position of the sensing magnet on the swing arm rotates and changes until it coincides with the position sensor. The vertical reset information can be detected by the position sensor. The swing arm can hook or cut the yarn during the swinging process.

[0008] The top of the swing arm is provided with mounting holes for fixing a component with yarn clamping and cutting functions; a wire pressing trigger is installed in the right cavity of the component's base, and a rotating hole is provided in the middle of the wire pressing trigger, which mates with a boss in the right cavity of the base.

[0009] The bottom of the wire pressing trigger is connected to a return spring. In the absence of external interference, the return force of the return spring can keep the wire pressing trigger in a vertical initial state. When the wire pressing trigger is rotated inward by external force to overcome the tension of the return spring, it can press into the groove of the grooved wire pressing seat to form a pressing mating surface.

[0010] The countersunk bolt pulls the upper hook of the reset spring, and the fastening bolt pulls the lower hook of the reset spring. The countersunk bolt and the fastening bolt also fix the wire pressing trigger in the right cavity of the base.

[0011] A telescopic cylinder is installed on the left cavity of the component's base. The end of the telescopic cylinder is connected to a slider joint. The telescopic cylinder's up and down movement can drive the slider joint to move together.

[0012] The right end face of the slider connector forms a contact-type pressing fit with the wire pressing trigger. When the telescopic cylinder extends and descends with the slider connector, the right end face of the slider connector will press the lower contact surface of the wire pressing trigger, causing the wire pressing trigger to rotate inward around the boss in the base cavity. At the same time, it overcomes the spring tension of the reset spring and presses against the grooved wire pressing seat until it is pressed tightly.

[0013] The left end face of the slider connector has a sliding groove, which slides into contact with the protrusion on the sliding lever.

[0014] The circular through hole on one side of the sliding paddle forms a concentric rotational fit with the shape pressing plate, the main cutter, and the auxiliary cutter. The sliding paddle has a threaded set hole that is fastened together with the main cutter, driving the main cutter to rotate.

[0015] The aforementioned plug nut, sliding washer, and locking bolt enclose the four assembly components—sliding paddle, shape pressing plate, main cutter, and secondary cutter—in the middle.

[0016] The secondary cutter is fixed to the left outer surface of the base. The main cutter and the secondary cutter form a scissor set. When the top of the telescopic cylinder extends or retracts, it drives the slider joint to extend or retract up and down, and drives the sliding paddle and the main cutter to rotate inward or outward within a certain range.

[0017] As an optimization: the output shaft end of the rotary actuator is connected to the swing arm.

[0018] As an optimization: the speed regulating air valve can adjust the rotational speed of the output shaft of the rotary actuator by the amount of compressed air entering and leaving the machine.

[0019] As an optimization: the swing arm's swing is controlled by PLC programming, and it can swing 90° to the left or 90° to the right.

[0020] As an optimization: the wire pressing trigger is an L-shaped structure.

[0021] As an optimization: the pressing surface of the wire pressing trigger and the mating surface of the grooved wire pressing seat are kept at a certain distance; the mating surface of the wire pressing trigger is one side of the grooved wire pressing seat.

[0022] As an optimization: the telescopic cylinder is fixed in a reserved position on the base, and the telescopic end of the telescopic cylinder is inserted into the groove cavity, allowing for a certain range of vertical extension and retraction.

[0023] As an optimization: when the telescopic cylinder extends downwards with the slider joint, the sliding paddle rotates inwards, causing the blade of the main cutter to move closer to the secondary cutter, satisfying the shearing action posture; when the telescopic cylinder retracts upwards with the slider joint, the sliding paddle rotates outwards, causing the blade of the main cutter to move away from the secondary cutter, satisfying the reset state.

[0024] As an optimization: the automatic yarn feeding and cutting device is a new type of automated, programmable, intelligent control type automatic yarn feeding and cutting auxiliary device, whose main functions are automatic yarn feeding and automatic tail cutting.

[0025] An application system for an automatic yarn feeding and cutting device includes an automatic yarn feeding and cutting device, a yarn to be wound, an automatic yarn feeding device, a feeding bobbin, and a winding and shaking frame; the yarn to be wound in the feeding bobbin passes through the automatic yarn feeding device, and then passes through the automatic yarn feeding and cutting device to grab the lead yarn or cut the tail yarn, and arrives at the winding and shaking frame for continuous winding.

[0026] Beneficial effects: The specific advantages of this invention are as follows:

[0027] 1. The system of the present invention replaces manual operation, helps manufacturing enterprises reduce labor costs, and significantly optimizes the production process.

[0028] 2. The system of the present invention has a higher degree of intelligence and automation, which makes the process of cutting the beginning and end of the yarn more convenient, the consistency of the beginning and end of the finished yarn is better, and the product quality is better.

[0029] 3. The system of the present invention has higher production efficiency and output per unit time. The original manual operation required repetitive labor and a lot of time, but now it can be completely replaced by this intelligent equipment, which promotes the automation process and rapid development of the yarn winding field.

Detailed Implementation

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below, so that those skilled in the art can better understand the advantages and features of the present invention, thereby making a clearer definition of the scope of protection of the present invention. The embodiments described in this invention are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Specific Implementation Example 1

[0047] like Figure 1 As shown, the general operation for processing the start and end of yarn in skein is as follows: The yarn start 50 to be wound onto the skein frame is manually placed into the edge slot of the skein frame 51. After the yarn start 50 is wound, the skein frame 51 is started to wind the yarn. After one skein is completed, the yarn end 52 is manually located and then cut off with scissors 53. This process is repeated to produce skeins of finished yarn. The above operation has the following disadvantages: 1) It relies entirely on manual labor, resulting in low efficiency and high time consumption; 2) Sudden rotation of the skein frame can easily lead to finger injuries or other accidents; 3) If the operator is not skilled, the yarn start may fall off and get caught, or the yarn end may be left too long, resulting in unnecessary waste. To overcome the shortcomings of the existing technology, this invention provides an automatic yarn start and cut system.

[0048] like Figure 2-3As shown, the application system of the automatic yarn feeding and cutting device of the present invention includes an automatic yarn feeding and cutting device 22, a yarn to be wound 23, an automatic yarn feeding device 24, a feeding bobbin 25, and a winding and shaking frame 26. The yarn to be wound 23 in the feeding bobbin 25 passes through the automatic yarn feeding device 24, and then passes through the automatic yarn feeding and cutting device 22 to grasp the leading yarn or cut the trailing yarn, before reaching the winding and shaking frame 26 for continuous winding. The automatic yarn feeding and cutting device 22 is a novel automated, programmable, intelligent control type auxiliary device for automatic yarn feeding and cutting, and its main functions are automatic yarn feeding and automatic tail cutting.

[0049] The specific advantages of this system are as follows: 1. Modular design and assembly, compact and intelligent; PLC programming control, adaptable to various frame lengths according to the extension and retraction of the yarn feeder; 2. High degree of automation, reducing labor costs and the labor intensity of process personnel, and improving production efficiency; 3. Possesses certain angle rotation and position calibration sensing functions, with high accuracy in yarn grabbing and yarn cutting; 4. When used in conjunction with an automatic yarn feeding device, it can form a complete solution for fully automatic continuous yarn production, maximizing the reduction of labor costs for manufacturing enterprises. The high consistency of yarn fixing and yarn cutting can significantly improve the consistency and reliability of finished product quality, helping enterprises improve product quality levels.

[0050] like Figure 4-14 As shown, an automatic wire feeding and cutting device includes a plug nut 1, a sliding pad 2, a sliding lever 3, a shape pressing plate 4, a main cutter 5, a secondary cutter 6, a telescopic cylinder 7, a base 8, a slider connector 9, a locking bolt 10, a wire pressing trigger 11, a countersunk bolt 12, a base plate 13, a fastening bolt 14, a reset spring 15, a rotary actuator 16, a position sensor 17, a sensor bracket 18, a speed regulating valve 19, a swing arm 20, and a grooved wire pressing seat 21.

[0051] A rotary actuator 16 is fixedly mounted on the bottom of the swing arm 20. Specifically, the output shaft end of the rotary actuator 16 is connected to the swing arm 20. The bottom of the rotary actuator 16 has mounting holes, allowing it to be mounted to the equipment base plate or the location where rotation is required. Two speed-regulating air valves 19 are provided on the side of the rotary actuator 16, which can adjust the rotation speed of the output shaft of the rotary actuator 16 by adjusting the amount of compressed air entering and exiting. A sensor bracket 18 is provided on the front end face of the rotary actuator 16, and a position sensor 17 is fixedly mounted on the sensor bracket 18.

[0052] A sensing magnet is installed in the small circular hole on the side of the swing arm 20 facing the rotary actuator 16. When the swing arm 20 rotates and swings with the output shaft of the rotary actuator 16, the position of the sensing magnet on the swing arm 20 rotates and changes until it coincides with the position sensor 17, and the vertical reset information can be detected by the position sensor 17. The swing of the swing arm 20 is controlled by PLC programming and can swing 90° to the left or 90° to the right. During the swing within the above angle range, the swing arm 20 can hook or cut the yarn.

[0053] The top of the swing arm 20 is provided with mounting holes for fixing a component with yarn clamping and cutting functions. A thread pressing trigger 11 is installed in the right cavity of the base 8 of the component. The thread pressing trigger 11 has an L-shaped structure and a rotating hole is provided in the middle position of the thread pressing trigger 11. The rotating hole cooperates with the boss in the right cavity of the base 8.

[0054] The bottom of the wire pressing trigger 11 is connected to a return spring 15. In the absence of external interference, the return force of the return spring 15 can keep the wire pressing trigger 11 in a vertical initial state (the pressing surface of the wire pressing trigger 11 and the mating surface of the grooved wire pressing seat 21 maintain a certain distance). The mating surface (pressing surface) of the wire pressing trigger 11 is one side of the grooved wire pressing seat 21. When the wire pressing trigger 11 rotates inward by overcoming the tension of the return spring 15 with external force, it can press into the groove of the grooved wire pressing seat 21 to form a pressing mating surface.

[0055] The countersunk bolt 12 pulls the upper hook of the reset spring 15, and the fastening bolt 14 pulls the lower hook of the reset spring 15. The countersunk bolt 12 and the fastening bolt 14 also fix the wire pressing trigger 11 in the right cavity of the base 8.

[0056] A telescopic cylinder 7 is installed on the left cavity of the base 8 of the component. Specifically, the telescopic cylinder 7 is fixed in a reserved position on the base 8, and the telescopic end of the telescopic cylinder 7 is engaged in the groove cavity, allowing for a certain range of vertical extension and retraction. The end of the telescopic cylinder 7 is connected to a slider joint 9, and the vertical extension and retraction of the telescopic cylinder 7 can drive the slider joint 9 to move together.

[0057] The right end face of the slider connector 9 forms a contact-type pressing fit with the wire pressing trigger 11. When the telescopic cylinder 7 extends and descends with the slider connector 9, the right end face of the slider connector 9 will press the lower contact surface of the wire pressing trigger 11, causing the wire pressing trigger 11 to rotate inward around the boss in the cavity of the base 8, while overcoming the spring tension of the reset spring 15 and pressing it against the grooved wire pressing seat 21 until it is pressed tightly.

[0058] The left end face of the slider connector 9 has a sliding groove, which slides into contact with the protrusion on the sliding paddle 3.

[0059] The circular through hole on one side of the sliding paddle 3 forms a concentric rotational fit with the shape pressing plate 4, the main cutter 5, and the secondary cutter 6. The sliding paddle 3 has a threaded set hole that is fastened together with the main cutter 5, which can drive the main cutter 5 to rotate.

[0060] The aforementioned plug nut 1, sliding pad 2, and locking bolt 10 enclose the four assemblies—sliding paddle 3, shape pressing plate 4, main cutter 5, and secondary cutter 6—in the middle.

[0061] The secondary cutter 6 is fixed to the left outer surface of the base 8 and cannot move. The main cutter 5 and the secondary cutter 6 form a scissor set. When the top of the telescopic cylinder 7 extends or retracts, it drives the slider connector 9 to extend or retract up and down, and drives the sliding paddle 3 and the main cutter 5 to rotate inward or outward within a certain range. Specifically, when the telescopic cylinder 7 extends downward with the slider connector 9, the sliding paddle 3 rotates inward, and the blade of the main cutter 5 moves closer to the secondary cutter 6, satisfying the cutting posture. When the telescopic cylinder 7 retracts upward with the slider connector 9, the sliding paddle 3 rotates outward, and the blade of the main cutter 5 moves away from the secondary cutter 6, satisfying the reset state. Specific Implementation Example 2

[0063] like Figure 15 As shown, an automatic yarn-forming and cutting mechanism includes two parts: a yarn-forming assembly and a yarn-forming auxiliary clamp. The yarn-forming assembly consists of a swing cylinder, a swing rod, a tail yarn shear, a spring block, a clamping cylinder, a clamping slider, a clamping swing rod, a return spring, and a base. When the yarn is caught in the assembly's clamping slot, the clamping cylinder extends, pushing the clamping slider forward, which in turn drives the clamping swing rod and the tail yarn shear to close. When the clamping slider is pushed to half its stroke, the clamping swing rod and the spring block close, clamping the yarn. When the clamping slider is pushed to its end, the tail yarn shear is fully closed, and the yarn is cut. This design ensures that the yarn is first clamped by the clamping swing rod before being cut, preventing the yarn from slipping out of the clamping slot during cutting.

[0064] The specific workflow of this invention is as follows:

[0065] a. When the winch finishes winding, the yarn feeding assembly is raised; the yarn tail is inserted into the feeding assembly slot, the clamping cylinder is activated, the yarn tail is cut off, and the yarn on the feeding side is clamped by the clamping swing rod.

[0066] b. After the yarn on the winch is unloaded, the winch unloading is completed, the winch is returned to zero, and the automatic yarn generation process begins;

[0067] c. When the starting assembly is lowered to a horizontal position, the starting yarn is straightened;

[0068] d. The winding turntable begins to rotate counterclockwise. During the rotation, the straightened yarn will be caught in the starter clip at the end of the turntable's support rod. At this time, the yarn between the starter clip and the starter assembly is the end of the yarn.

[0069] e. Adjusting the length of the yarn end: First, loosen the yarn end assembly, then tighten the yarn end auxiliary clamp to hold the yarn in place. Next, rotate the turntable counterclockwise by a certain angle to shorten the yarn end length to the target value.

[0070] f. Finally, release the head-growing clips to complete the head-growing process.

[0071] The system of this invention has a high degree of automation, high work efficiency, and intelligent control. It can adjust the length of the tail according to the specific yarn, effectively preventing the tail from tangling or falling off, thus promoting the automation process and rapid development in the field of yarn winding.
