[0003] A twisting machine is a machine that winds the bobbin yarn on a rotating yarn frame to form a twist. The current twisting machine generally includes a frame, a rotating yarn frame connected to the frame, and a motor or a crank that drives the rotating yarn frame to rotate. After the bobbin yarn is wound on the rotating yarn frame for a certain number of turns, a twisted yarn is formed. At present, the existing twisting process is still in the semi-automatic stage: workers manually make the yarn, the machine twists it, and then the double-∞-shaped strands are manually tied and knotted, and finally the twisted yarn is taken out from the yarn frame.

DETAILED DESCRIPTION

[0031] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1 and 2 As shown, an automatic shaking and twisting machine includes an electrical box 1, a base 2, a bracket 3, a wire moving assembly 4, a yarn frame assembly 5, a transverse movement assembly 6, a head assembly 7, a stranding, twisting and knotting assembly 8, a yarn dropping assembly and a yarn storage assembly 10. The wire moving assembly 4 is arranged at one end of the bracket 3 for realizing the wire moving of the yarn, the yarn frame assembly 5 is arranged on both sides of the bracket 3 for shaking and twisting the yarn, the transverse movement assembly 6 is arranged at the upper end of the bracket 3 for driving the head assembly and the stranding, twisting and knotting assembly to move forward and backward, the head assembly 7 is connected to the bottom of the transverse movement assembly for cutting the yarn and clamping the yarn tail, the stranding, twisting and knotting assembly 8 is connected to the transverse movement assembly 6 for dividing the shaken yarn and automatically twisting it, the yarn dropping assembly is movably arranged on both sides of the base for removing the twisted yarn on the yarn frame and transporting it to the yarn storage assembly, and the yarn storage assembly 10 is arranged at one end of the base 2 for hanging the twisted yarn.

[0033] like Figure 3 As shown, the wire moving assembly 4 includes a wire moving base 4-1, a wire moving motor 4-2, a primary synchronous belt 4-3, a secondary synchronous belt 4-4, a guide post 4-5, a wire moving seat 4-6, and a wire guide hook 4-7; the wire moving motor 4-2 is mounted on the wire moving base 4-1, and drives two primary synchronous belts 4-3 respectively, and then drives the two left and right secondary synchronous belts 4-4. The wire moving seat 4-6 is fixed on the secondary synchronous belt 4-4 and can slide on the guide post 4-5, and each wire moving seat is equipped with a wire guide hook 4-7. In this way, the wire moving motor 4-2 can drive the four left and right wire guide hooks 4-7 to move back and forth by constantly rotating forward and reverse, thereby realizing the yarn moving.

[0034] like Figure 4 As shown, the transverse moving assembly 6 includes a cross beam 6-1, a transverse moving guide rail 6-2, a transverse moving motor 6-3, a transverse moving rack 6-4 and a transverse moving frame 6-5. The cross beam 6-1 is mounted on the bracket 3, on which the transverse moving guide rail 6-2 and the transverse moving rack 6-4 are installed, and the transverse moving frame 6-5 is seated on the linear guide rail 6-2. The transverse moving motor 6-3 is engaged with the rack 6-4 through the gear, and drives the transverse moving frame 6-5 to move horizontally on the cross beam 6-1.

[0035] like Figure 5As shown, the head assembly 7 includes a head base 7-1, a head bracket 7-2, a lifting guide rail 7-3, a lifting cylinder 7-4, a double-shaft motor 7-5, a coupling 7-6 and a clamping and shearing device 7-7. The head base 7-1 is fixed on the transverse frame 6-5 so that it can move horizontally with the transverse frame 6-5. The head base 7-1 is installed with a lifting guide rail 7-3, and the head bracket 7-2 is installed on the lifting guide rail 7-3, and is driven by the lifting cylinder 7-4 so that it can move up and down in the vertical direction. The head bracket 7-2 is installed with a double-shaft motor 7-5 and four groups of clamping and shearing devices 7-7, which are interconnected by a coupling 7-6, so that the synchronous clamping and shearing of the four groups of devices can be achieved.

[0036] like Figure 6 As shown, the clamping and cutting device 7-7 clamps and releases the skein yarn 13 by driving the left fixed seat 7-71 and the right fixed seat 7-72. The left fixed seat 7-71 and the right fixed seat 7-72 ​​are slidably connected with two long guide pins 7-74 and two short guide pins 7-75 through bearings 7-73. One end of the long guide pin 7-74 and the short guide pin 7-75 is processed with a step plug in the fixed seat to prevent sliding from one direction of the fixed seat, and the other end is fixedly connected with a pressure block 7-76 for clamping the tail of the skein yarn. The clamping force is provided between the pressure block 7-76 and the fixed seat by a clamping spring 7-77 with different pre-compression amounts on the long guide pin 7-74 and the short guide pin 7-75. The difference between the left and right fixed seats is that one side is fixedly connected with a blade 7-78, and the other side is fixedly connected with a wire groove 7-79 that matches the blade 7-78. The blade 7-78 and the wire groove 7-79 work together to cut the tail of the skein of yarn while clamping the tail of the skein of yarn on both sides at the same time. Among them, a pair of pressing blocks 7-76 fixedly connected to the short guide pin 7-75 are close to the shaking yarn frame, and a pair of pressing blocks 7-76 fixedly connected to the long guide pin 7-74 are far away from the shaking yarn frame. In the process of the distance between the left and right fixed seats approaching, the pair of pressing blocks 7-76 fixedly connected to the long guide pin 7-74 first contact each other, followed by the pair of pressing blocks 7-76 fixedly connected to the short guide pin 7-75, and finally the blade 7-78 and the wire groove 7-79 interact with each other. In the process of the distance between the left and right fixed seats moving away, the blade 7-78 and the wire groove 7-79 first separate from each other, followed by the pair of pressing blocks 7-76 fixedly connected to the short guide pin 7-75, and finally the pair of pressing blocks 7-76 fixedly connected to the long guide pin 7-74.

[0037] like Figures 7 to 10As shown, the threading device 8-3 is mainly composed of an upper spray suction nozzle 8-4 and a lower spray suction nozzle 8-8 with the same functions, forming a "C" shaped structure. Taking the upper spray suction nozzle 8-4 as an example, it is connected to two air pipes, namely: an upper suction pipe 8-6 and an upper nozzle 8-7. One end of the upper suction pipe 8-6 is connected to the mouth, and the other end is connected to a negative pressure generator (not shown), through which negative pressure is generated in the spray suction pipe to suck in the yarn. The upper nozzle 8-7 is connected to the upper flow channel 8-5 facing the mouth. Since the aperture of the upper flow channel 8-5 is very small, the flow rate of compressed air becomes faster when it flows through the upper flow channel, so that the air can blow out the yarn in the upper suction pipe 8-6 when it flows out of the mouth. The specific strand binding and twisting process is as follows:

[0038] First, the yarn frame rotates to drive the twist rod to rotate so that the yarn is wound and forms a skein. Before shaking, the yarn head is fixed to one side of the skein position by the clamping assembly. After shaking, the yarn tail 9 is also moved to the same position by the wire moving assembly, and then cut and clamped. Then the upper nozzle 8-4 generates negative pressure, and the binding strand 14 is sucked into the upper suction pipe 8-6. The threading device 8-3, together with the left threading rod 8-1 and the right threading rod 8-2, falls from just above the horizontal skein. The left threading rod 8-1 and the right threading rod 8-2 penetrate into the skein and divide the skein into three parts, completing the stranding action.

[0039] After the stranding is completed, the threading device 8-3 drives the tied strand 14 to start moving to the left. When the mouths of the upper spray suction nozzle 8-4 and the lower spray suction nozzle 8-8 of the threading device move to the center of the right threading rod 8-2, the upper spray suction nozzle 8-4 starts to spray air to blow out the tied strand located in the upper suction pipe 8-6. At the same time, the lower spray suction nozzle 8-8 starts to inhale, and immediately sucks the tied strand 14 blown out from the upper spray suction nozzle 8-4 into the lower suction pipe 8-10, thereby realizing the position conversion of the tied strand 14 from top to bottom. Similarly, when the mouth moves to the center of the left threading rod 8-1 and the left side of the skein, the upper and lower positions of the tied strand are interchanged through the cooperation of the upper and lower spray suction nozzles, and finally the threading device returns to the right until the mouth is aligned with the center of the yarn head 8-19 and the yarn tail 8-20, so that the tied strand is threaded around the skein in the shape of a double "∞" character. In particular, in order to prevent the entangled stranded wire from affecting the thread threading during the return process, the threading device moves a distance L towards the threading rod when it moves to the leftmost side, so as to avoid threading failure during the return process.

[0040] Afterwards, the threading device 8-3 and the left and right threading rods 8-1 and 8-2 are lifted upward, and the lower suction nozzle 8-8 also starts to suck air. At the same time, the clamping components of the yarn head and yarn tail are loosened, so that the yarn head and tail together with the binding wire are sucked into the lower suction nozzle 8-8 and lifted above the knotting device. Finally, the upper thread shifting rod 8-17 and the lower thread shifting rod 8-18 make a fixed-axis rotation to shift the tying twisted wire 14, the yarn head 8-19 and the yarn tail 8-20 to the center of the knotting upper baffle 8-13 and the knotting lower baffle 8-14 on the knotting device 8-12, and then the yarn gathering upper baffle 8-15 and the yarn gathering lower baffle 8-16 push all the lines to the knotting upper baffle 8-13 and the knotting lower baffle 8-14. Since these are "V"-shaped baffles, the four lines are gathered at the two concave points of the upper and lower baffles to form a yarn, which is then knotted by the knotting device to complete the tying and twisting action.

[0041] like Figures 11 to 13 As shown, when the yarn dropping assembly starts working, it is in the skein storage area and directly opposite to the yarn storage assembly, the yarn pushing actuator 9-15 is at a position far from the skein, and the upper yarn pushing plate 9-1510 and the lower yarn pushing plate 9-1511 are at a position far from the skein and remain horizontal. Then the entire device moves horizontally to the yarn dropping work area and directly opposite to the shaking device. The yarn pushing actuator 9-15 moves longitudinally to a position near the skein, and at the same time, the upper yarn pushing plate 9-1510 and the lower yarn pushing plate 9-1511 move longitudinally to a position near the skein and still remain horizontal, and at this time, the upper and lower yarn pushing actuators have extended into the shaking device. Then, the shaking device moves to relax the upper yarn and falls onto the upper and lower yarn pushing actuators 9-15. Next, the upper yarn pushing plate 9-1510 and the lower yarn pushing plate 9-1511 rotate 90° to a vertical state, and then the upper yarn pushing plate 9-1510 and the lower yarn pushing plate 9-1511 move back longitudinally, and at the same time, the yarn pushing actuator 9-15 moves back longitudinally. The distance moved by the upper yarn pushing plate 9-1510 and the lower yarn pushing plate 9-1511 plus the distance moved by the yarn pushing actuator 9-15 can make the skein completely detach from the shaking device and fall on the yarn pushing actuator. Then the whole device returns to the skein storage area, and prepares to put the yarn on the yarn pushing actuator on the yarn storage rack, and at the same time, the shaking device also returns to its original position. Similarly, through the movement and coordination of the upper yarn pushing plate 9-1510, the lower yarn pushing plate 9-1511 and the yarn pushing actuator 9-15, the skein on the yarn pushing actuator 9-15 falls completely on the yarn storage rack.

[0042] like Fig.14As shown, the yarn storage assembly 10 includes a yarn storage base 10-1, a main shaft 10-2 and a yarn storage frame 10-3. Eight pairs of yarn storage frames 10-3 are installed on the main shaft 10-2, and the main shaft 10-2 can be driven by a motor to rotate on the yarn storage base 10-1, driving one pair of yarn storage frames 10-3 to be perpendicular to the traverse assembly 6, so that the yarn on the sand falling assemblies 9-1 and 9-2 can be conveniently placed on the yarn storage frame 10-3.

[0043] In summary, different groups of yarn frame components 5 and wire moving components 4 can be set according to the matching of the binding and knotting time and the shaking time. For example, when the yarn is thinner and the shaking time is longer, 6 minutes, and the stranding time is 2 minutes, four groups of yarn frames and wire moving components should be set; when the yarn is thicker and the shaking time is shorter, 2 minutes, and the stranding time remains unchanged, two groups can meet the requirements. Figure 1 , Figure 2 As shown, the machine takes three groups of yarn frame assemblies 5 as an example, and each group of yarn frame assemblies can shake four groups of twisted yarns 11 symmetrically on both sides. Four groups of stranding, twisting and knotting assemblies 8 are installed on the corresponding transverse frame 6-5, so that they can move back and forth on the crossbeam 6-1 together with the yarn assembly 7. The left and right sand dropping assemblies 9-1 and 9-2 are respectively installed on the two sides of the base 2, and can move back and forth between the yarn frame assembly 5 and the yarn storage assembly 10, so as to facilitate the placement of the shaken yarn 12 on the yarn storage frame 10-3.

[0044] First, the first artificial yarn-spinning clamps the twelve yarn ends on the upper components 5 of the three groups of yarn frames. After that, the yarn frames rotate to start the wire movement and start shaking and twisting. When a group of yarn frames is fully twisted, the lateral movement component 6 drives the yarn-spinning component 7 and the strand-binding and knotting component 8 to come to the top of the yarn frame of this group. The lifting cylinder 7-4 drives the yarn-spinning bracket 7-2 to move downward to the clamping position, and the double-output shaft motor 7-5 rotates to drive the clamping and cutting device 7-7 to cut and clamp the yarn tail. After that, the four-group strand-binding and knotting components start strand-binding and knotting. When the binding and twisting are completed, the left and right sand-dropping components 9-1 and 9-2 move to the yarn frame of this group to drop the sand, and then the four strands of yarn are sent to the yarn rack of the yarn storage component 10. Finally, the lifting cylinder 7-4 is retracted, and the lateral movement component 6 moves horizontally for a distance, and then the yarn head is clamped by the yarn-spinning component 7 to spin the yarn. After the yarn is finished, the traverse assembly 6 moves to the next set of yarn frames for automatic tying and twisting, and the yarn frame with the yarn finished can start the next round of shaking and twisting. After a set of yarn storage racks 10-3 are full of skeins, they can be rotated at a certain angle to replace the yarn racks. When the yarn storage racks are almost full, the workers are reminded to unload the yarn.

[0045] This device can realize the whole process of automatic shaking and twisting from yarn production, stranding, binding, knotting to yarn doffing, greatly reducing the labor intensity of industrial workers. The high-speed shaking and twisting of the short yarn frame, coupled with the high efficiency of non-stop stranding, binding, twisting and knotting, can bring huge social and economic benefits.

Those skilled in the art should understand that the above embodiments do not limit the protection scope of the present invention in any form, and all technical solutions obtained by equivalent replacement and the like fall within the protection scope of the present invention.
