Description

Technical Field

[0001] The present invention relates to the technical field of doubling twisting machines, and in particular, to an emergency braking mechanism for a doubling twisting machine and a control method therefor. Background Art

[0002] A twisting machine is a twisting device which is essentially a wire merging device (merging multiple strands into one), called a wire merging machine, without specific Chinese or English names. It can achieve two twists in one revolution, with the twisting efficiency being increased several times compared to traditional twisting equipment, the winding capacity being increased, no joints in ten thousand meters, the twisting quality being greatly improved, a lower floor height, being particularly suitable for operation. The wire merging machine can twist and bond two or more single yarns into a ply yarn through twisting, and enhance the performance of the original yarn to meet the requirements of customers.

[0003] In the prior art, a doubling twisting machine with convenient cleaning, with the publication number of CN218491907U, includes a doubling twisting machine frame. The inner wall of the doubling twisting machine frame is fixedly connected with a blower and a filter air box, and the output end of the blower is fixedly connected with the inner wall of the filter air box. Place the bobbin in the bobbin tube, pass the silk thread through the spindle assembly, air guiding ring, wire guiding plate, first wire guiding wheel, second wire guiding wheel and wire guiding ring, and then wind the silk thread around the winding tube to start the doubling twisting work. Start the blower to filter the dust in the air through the filter air box and blow it into the first air duct and blow it out through the air guiding ring. The air enters the second air duct and the air is blown onto the surface of the winding tube through the air guiding cover to perform two dust removals on the silk thread, achieving the goal of facilitating the automatic dust removal and cleaning of the silk thread of the doubling twisting machine, avoiding the problem that after the doubling twisting machine is used for a long time and dust accumulates on the surface of the spindles and the machine frame, the silk thread is stained with dust for a long time, resulting in the color and quality of the silk thread being affected, and it is very convenient to use.

[0004] However, when the above doubling twisting machine is in use, although it can perform a good cleaning operation on the dust sucked and sealed on the doubling twisting machine, during the daily use of the doubling twisting machine, there is a lack of an emergency braking mechanism for automatically monitoring and identifying the bobbin tube on the doubling twisting machine. When there is an abnormality in the bobbin tube on the doubling twisting machine, the doubling twisting machine cannot be locked and braked in time, reducing the maintenance efficiency of the bobbin tube, and further reducing the overall operating efficiency of the doubling twisting machine. At the same time, when monitoring the emergency braking of the bobbin tube on the doubling twisting machine, the all-round adjustment and monitoring effect on the bobbin tube is not high, and when the bobbin tube is rotating normally, the synchronous limiting effect on the bobbin tube is not high, which does not meet the usage requirements of people. Therefore, we propose an emergency braking mechanism for a doubling twisting machine and a control method therefor. Summary of the Invention

[0005] To solve the problems mentioned in the above background, the present invention provides an emergency braking mechanism for a doubling twisting machine and its control method, so as to solve the problem that there is a lack of an emergency braking mechanism for automatically monitoring and identifying the bobbin on the doubling twisting machine, resulting in the inability to promptly lock and brake the doubling twisting machine when there is an abnormality in the bobbin on the doubling twisting machine, and reducing the maintenance efficiency of the bobbin.

[0006] To achieve the above technical objectives, the technical solutions adopted by the present invention are as follows:

[0008] The doubling twisting machine body further includes:

[0009] A monitor body, which is arranged on the top of the doubling twisting machine body and is used to monitor the motion state of the bobbin;

[0010] A locking mechanism, which is arranged on the outer wall of the connecting shaft and is used to emergently brake the connecting shaft;

[0011] The locking mechanism includes a friction plate and a limiting block. The monitor body is slidably connected to the outer wall of the doubling twisting machine body.

A connecting rod is slidably connected to the outer wall of the lifting block. A limiting block located on one side of the connecting shaft is fixedly connected to the outer wall of the connecting rod. A friction plate for braking the connecting shaft is arranged on the outer wall of the swing rod.

[0012] Preferably, the moving distance of the monitor body is adapted to the length of the bobbin, and the outer wall contour of the connecting part between the limiting block and the connecting shaft is arc-shaped.

[0013] Preferably, a limiting groove is opened at the connecting part between the outer wall of the swing rod and the lifting block, and the swing rod and the lifting block are slidably connected.

[0014] Preferably, a threaded rod threadedly connected to the outer wall of the monitor body is rotatably connected to the top of the doubling twisting machine body. A first servo motor for driving the threaded rod to rotate is arranged on the outer wall of the doubling twisting machine body.

[0015] Preferably, the monitor body reciprocally slides on one side of the bobbin through the rotation of the threaded rod, so as to automatically identify and monitor the motion of the bobbin in all directions.

[0016] Preferably, a rotating rod is rotatably connected to the outer wall of the doubling machine body. The doubling machine body is provided with a second servo motor for driving the rotating rod to rotate. A pulling rod for driving the lifting block to slide is rotatably connected to the outer wall of the rotating rod.

[0026] 2. The swing rod provided in the present invention drives the lifting block to slide along the inner wall of the limiting groove. At the same time, the rotation of the swing rod drives the friction plate to perform emergency braking on the connecting shaft, improving the effect of emergency braking and maintenance of the bobbin.

[0027] 3. The limiting block provided in the present invention, when the spool tube is in normal use, through the movement of the lifting block and under the connection of the connecting rod, drives the limiting block to slide centeringly along the outer wall of the connecting shaft, playing a role in synchronously limiting the connecting shaft during rotation.

[0038] To further illustrate the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in combination with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present invention as follows.

[0039] Embodiment 1:

[0040] Please refer to Figures 1 to 8, this embodiment provides a double-twisting machine emergency braking mechanism and its control method, including a double-twisting machine body 1. A connecting shaft 10 is rotatably connected to the outer wall of the double-twisting machine body 1. A processing motor 2 for driving the connecting shaft 10 to rotate is installed on the outer wall of the double-twisting machine body 1. A spool cylinder 3 is fixedly connected to the outer wall of the connecting shaft 10. A spindle assembly 4 is arranged on the outer wall of the double-twisting machine body 1 and is located below the spool cylinder 3.

[0041] Embodiment 2:

[0042] Based on Embodiment 1, the locking mechanism 9 is further disclosed.

[0043] As Figures 1 - 8 shown, the double-twisting machine body 1 further includes:

[0044] A monitor body 7, arranged on the top of the double-twisting machine body 1, for monitoring the motion state of the spool cylinder 3;

[0045] A locking mechanism 9, arranged on the outer wall of the connecting shaft 10, for emergently braking the connecting shaft 10;

[0046] The locking mechanism 9 includes a friction plate 908 and a limit block 910. The monitor body 7 is slidably connected to the outer wall of the double-twisting machine body 1. A speed sensor 701 is arranged at the bottom of the monitor body 7. A displacement sensor 702 is arranged at the bottom of the monitor body 7. A camera 703 is arranged at the bottom of the monitor body 7. A swing rod 906 is rotatably connected to the outer wall of the double-twisting machine body 1. A lifting block 904 for driving the swing rod 906 to rotate is slidably connected to the outer wall of the double-twisting machine body 1. A connecting rod 909 is slidably connected to the outer wall of the lifting block 904. A limit block 910 located on one side of the connecting shaft 10 is fixedly connected to the outer wall of the connecting rod 909. A friction plate 908 for braking the connecting shaft 10 is arranged on the outer wall of the swing rod 906. After judging that emergency braking is required, the monitor transmits the braking information to the second servo motor 901 through the connecting line 8. The second servo motor 901 starts to drive after receiving the signal. The driving of the second servo motor 901 rotates the rotating rod 902, drives the pulling rod 903 to rotate. The rotation of the pulling rod 903 drives the lifting block 904 to slide along the inner wall of the lifting groove 905 and drives the lifting block 904 to slide along the inner wall of the limit groove 907, causing the swing rod 906 to rotate relatively. The rotation of the swing rod 906 drives the friction plate 908 to contact the connecting shaft 10, emergently braking the connecting shaft 10, so that the spool cylinder 3 is in an emergency shutdown state, and timely cleaning and maintenance operations are carried out on the impurities existing on the surface of the spool cylinder 3. At the same time, when the spool cylinder 3 rotates normally, the reverse movement of the lifting block 904 drives the limit block 910 to move closer to the connecting shaft 10 through the connection of the connecting rod 909, playing a role in normally limiting the connecting shaft 10.

[0047] As Figure 2 and Figure 3As shown, the moving distance of the monitor body 7 is set to be adapted to the length of the spool cylinder 3. The outer wall contour of the connecting part between the limit block 910 and the connecting shaft 10 is arc-shaped, which is conducive to the all-round adjustment and monitoring of the spool cylinder 3 by setting the moving distance of the monitor body 7 to be adapted to the length of the spool cylinder 3.

[0048] As Figure 8 shown, a limit groove 907 is opened at the connecting part between the outer wall of the swing rod 906 and the lifting block 904. The swing rod 906 and the lifting block 904 are slidably connected, which is conducive to driving the swing rod 906 to rotate conveniently through the opening of the limit groove 907.

[0049] As Figure 4 shown, a threaded rod 6 that is threadedly connected to the outer wall of the monitor body 7 is rotatably connected to the top of the doubling machine body 1. A first servo motor 5 for driving the threaded rod 6 to rotate is arranged on the outer wall of the doubling machine body 1, which is conducive to the drive of the first servo motor 5. Through the rotation of the threaded rod 6, the monitor body 7 is driven to reciprocally slide along the outer wall of the doubling machine body 1, playing a role in all-round adjustment and monitoring of the usage state of the spool cylinder 3.

[0050] As Figure 3 and Figure 4 shown, the monitor body 7 reciprocally slides on one side of the spool cylinder 3 through the rotation of the threaded rod 6, which is used for all-round automatic recognition and monitoring of the movement of the spool cylinder 3. It is conducive to the monitor body 7 reciprocally sliding on one side of the spool cylinder 3 through the rotation of the threaded rod 6, playing a role in all-round adjustment and monitoring of the usage state of the spool cylinder 3.

[0051] As Figure 7 shown, a rotating rod 902 is rotatably connected to the outer wall of the doubling machine body 1. A second servo motor 901 for driving the rotating rod 902 to rotate is arranged on the doubling machine body 1. A pulling rod 903 for driving the lifting block 904 to slide is rotatably connected to the outer wall of the rotating rod 902. A lifting groove 905 for limiting the movement of the lifting block 904 is opened on the outer wall of the doubling machine body 1.

[0052] As Figure 7 shown, the lifting block 904 is slidably connected to the doubling machine body 1 through the lifting groove 905. The pulling rods 903 are equidistantly distributed about the rotation center of the rotating rod 902, which is conducive to the lifting block 904 being slidably connected to the doubling machine body 1 through the lifting groove 905, playing a role in driving the swing rod 906 to rotate conveniently, and achieving the effect of driving the friction plate 908 to be used conveniently.

[0053] As Figure 5 shown, a connecting line 8 for driving the second servo motor 901 is fixedly connected to the outer wall of the monitor body 7, which is conducive to playing a role in quickly transmitting the emergency braking signal through the setting of the connecting line 8.

[0054] Embodiment 3:

[0055] Based on Embodiments 1 and 2, an emergency braking control method for an emergency braking mechanism of a doubling machine is further disclosed, including the following steps:

[0056] Step S1: The monitor body 7 measures the continuous rotation speed of the bobbin 3 through the speed sensor 701;

[0057] Step S2: The monitor body 7 measures the displacement of the bobbin 3 under the continuous rotation state through the displacement sensor 702;

[0058] Step S3: The monitor body 7 collects the situation of obstacles on the surface of the bobbin 3 through the camera 703 and judges whether emergency braking is required.

[0059] Step S4: After judging that emergency braking is required, the monitor transmits the braking information to the second servo motor 901 through the connecting wire 8. The second servo motor 901 starts to drive after receiving the signal. The drive of the second servo motor 901 rotates the rotating rod 902, drives the pulling rod 903 to rotate. The rotation of the pulling rod 903 drives the lifting block 904 to slide along the inner wall of the lifting groove 905 and drives the lifting block 904 to slide along the inner wall of the limiting groove 907, causing the swing rod 906 to rotate relatively. The rotation of the swing rod 906 drives the friction plate 908 to contact the connecting shaft 10, performs emergency braking on the connecting shaft 10, makes the bobbin 3 in an emergency stop state, and timely cleans and repairs the impurities existing on the surface of the bobbin 3.

Although the present invention has been disclosed above with the preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
