Description

Technical Field

[0001] The invention relates to the technical field of thread twisting monitoring, in particular to a thread twisting monitoring device for a glass fiber twisting machine. Background Art

[0002] A twisting machine is a textile machinery equipment that twists multiple strands of yarn into one strand. Its function is to process yarn or combined strands of yarn into linear products for weaving and knitting. A twisting machine usually includes a twisting machine body and a circuit part, in which the spindle outside the body is connected to the motor output shaft of the circuit part to achieve the twisting of the yarn. In the production process of the glass fiber twisting machine, the length and quality of the yarn are key indicators. Therefore, installing a twist monitoring device is of great significance to ensure that the yarn length meets the requirements and improve production efficiency and product quality.

[0003] In the prior art, the traditional yarn twisting machine only has a yarn break sensor, which can stop the single-spindle motor in time when the yarn breaks. There is no flash frequency meter monitoring device, and there is no device to monitor the YARN (twisted glass fiber yarn) during the operation of the twisting motor. During the operation of the equipment, it is impossible to detect whether the speed of the single-spindle motor reaches the set value, and it is impossible to ensure that the twist of each YARN (twisted glass fiber yarn) is normal. Abnormal speed cannot be discovered in time to stop in time to reduce losses. In addition, it is impossible to see whether there are any abnormalities on the surface of the YARN (twisted glass fiber yarn) or whether there are too many hairiness during operation, so as to stop in time to reduce losses.

[0004] Therefore, the present invention proposes a twisting monitoring device for a glass fiber twisting machine to solve the problem that the actual speed of the high-speed motor cannot be monitored during the twisting process of the twisting machine due to the high-speed operation of the motor.

Through the installed monitoring device bracket 4, YARN (monitoring of the glass fiber yarn after twisting) during the twisting process is realized, and multiple groups of flash frequency meters 6 monitor whether the motor speed of each spindle is abnormal at any time. The flash frequency is close to the motor speed. The setting of the flipping mechanism 5 is used to ensure that when the yarn twisting is completed and the yarn dropping operation is required, the monitoring device bracket 4 can be flipped up as a whole. While not affecting the yarn dropping operation, it ensures that the twisting process of the yarn twisting machine is more comprehensive, reducing the production of a large number of defective products due to spindle abnormalities due to various reasons, causing waste, and reflecting the practicality of the equipment; with the optimized design of the assembly mechanism 9, it is convenient for the quick assembly of the flash frequency meter 6 and the yarn break automatic stop sensor 7, which is convenient for the yarn twisting operation and easy for disassembly and maintenance, and has high practicality.

[0021] Embodiment 2 On the basis of Example 1, in order to achieve the adaptive installation between the flash frequency meter 6, the yarn break automatic stop sensor 7 and the monitoring device bracket 4: the U-shaped seat 91 is movably installed on the outer side of the monitoring device bracket 4, and the U-shaped seat 91 is an "I"-shaped plate structure as a whole. The flash frequency meter 6 and the yarn break automatic stop sensor 7 are fixedly installed on the outer surface of one side of the U-shaped seat 91. The outer surfaces of both sides of the U-shaped seat 91 are fixedly installed with side support plates 911, and the inner walls of the side support plates 911 are provided with limited hole grooves 912; the locking assembly includes a turning handle 92, the outer surface of the turning handle 92 is rotatably connected to the inner wall of the monitoring device bracket 4, one end of the turning handle 92 is rotatably connected to the inner wall of the reserved square groove 80, and the outer surface of the turning handle 92 is fixedly installed A connecting gear cylinder 921 is installed, and the outer surfaces of both sides of the connecting gear cylinder 921 are respectively meshed and rotated with a meshing gear rod 1 922 and a meshing gear rod 2 923, and the outer surfaces of the meshing gear rod 1 922 and the meshing gear rod 2 923 are respectively fixed with protrusions; the protrusions and the meshing gear rod 1 922 and the meshing gear rod 2 923 are an integrally formed structure, and a movable groove 40 is opened on the inner wall of the reserved square groove 80, and the inner surface of the movable groove 40 is slidably connected with the outer surface of the protrusion; the outer ends of the meshing gear rod 1 922 and the meshing gear rod 2 923 are fixedly installed with a rounded plug-in terminal 924, and the outer surface of the rounded plug-in terminal 924 is movably abutted with an elastic block 913, and the elastic block 913 is fixedly installed on the inner surface of the limiting hole groove 912; Before the yarn twisting operation, the flash frequency meter 6 and the yarn break automatic stop sensor 7 are installed. The frequency of each flash frequency meter 6 is synchronized with the frequency of the yarn twisting spindles of the yarn twisting machine body 1. A starting switch of the flash frequency meter is added to the control panel. When the personnel patrol, turn on the switch and the flash frequency meter works. After the personnel leave, the switch can be turned off and the flash frequency meter is turned off. The winding state of the yarn can be monitored through the characteristics of the flash frequency meter, and the turning on and off of the flash frequency meter does not affect the normal use of the yarn break automatic stop sensor 7. The flash frequency meter 6 and the yarn break automatic stop sensor 7 are respectively installed on one side of the two groups of U-shaped seats 91. Then, the other side of the U-shaped seat 91 is abutted against the outer side surface of the monitoring device bracket 4. At this time, manually grasp the turning handle 92 and rotate it clockwise. At this time, the connecting gear cylinder 921 rotates synchronously, and the meshing gear rod 1 922 and the meshing gear rod 2 9 23 In the state of matching teeth, they move to both sides in relative position. Under the continuous rotation of the handle 92, the rounded plug-in terminal 924 connected to the outer end of the meshing gear rod 1 922 and the meshing gear rod 2 923 is respectively passed through the inner side of the limiting hole groove 912 provided on the side support plate 911. At this time, the meshing gear rod 1 922 and the meshing gear rod 2 923 complete the locking between the side support plate 911; the reason why the elastic block 913 is added on the inner side of the limiting hole groove 912 is to be able to rely on the elastic force storage of the elastic block 913 to abut the outer side of the rounded plug-in terminal 924, so as to achieve the locking of the meshing gear rod 1 922 and the meshing gear rod 2 923, further enhance the locking effect between the side support plate 911 and the monitoring device bracket 4, ensure that the twisting process monitoring of the yarn twisting machine is more comprehensive, and improve the yield rate of the glass fiber twisting.

[0022] Embodiment 3 On the basis of the second embodiment, in order to prevent the rotation handle 92 from accidentally touching and rotating, thus affecting the locking of the meshing rack one 922 and the meshing rack two 923: The anti-rotation assembly 10 includes an outer sleeve ring 101, and the outer sleeve ring 101 is fixedly installed on the inner surface of the reserved circular hole 8. The outer sleeve ring 101 is in a ring-shaped frame structure. An inner ring surface 102 is provided on the inner side surface of the outer sleeve ring 101. An installation groove plate 103 is fixedly installed on the inner surface of the inner ring surface 102. There are multiple groups of installation groove plates 103, and the multiple groups of installation groove plates 103 are circularly arrayed about the central axis of the inner ring surface 102; The installation groove plate 103 is in a "C"-shaped plate structure. An installation groove 1030 is opened on the inner side of the installation groove plate 103. A soft abutting elastic block 1031 is fixedly installed on the inner wall of the installation groove 1030. The cross-section of the soft abutting elastic block 1031 is in a "T"-shaped structure. Side grooves 1032 are respectively opened on both sides of the soft abutting elastic block 1031. An elastic push piece 1033 is fixedly installed on the inner surface of the side groove 1032. The other end of the elastic push piece 1033 is fixedly connected to the inner wall of the installation groove 1030. The elastic push piece 1033 is in an "X"-shaped plate structure, and the elastic push piece 1033 is symmetrically distributed about the longitudinal central axis of the soft abutting elastic block 1031; When the rotation handle 92 rotates and the meshing rack one 922 and the meshing rack two 923 are inserted into the inner side of the limit hole groove 912 for locking, during the rotation process of the rotation handle 92, the installation groove plates 103 on the inner side of the outer sleeve ring 101 are evenly distributed. The soft abutting elastic blocks 1031 installed on the inner side thereof are subjected to a certain abutment due to the rotation of the outer rotation handle 92, providing a certain resistance to the rotation handle 92, and through its elastic acting force, it will not affect the rotation of the rotation handle 92. When the soft abutting elastic block 1031 is extruded by an external force, it generates a certain elastic deformation, and at this time, the elastic push pieces 1033 on both sides are compressed synchronously. When the operator releases the rotation handle 92 and stops rotating, at this time, the soft abutting elastic block 1031 and the elastic push piece 1033 generate a reverse elastic acting force, thereby restricting the rotation handle 92, preventing the rotation handle 92 from rotating randomly when in the non-use state, thus causing the locking failure of the meshing rack one 922 and the meshing rack two 923. It further ensures the stability of the installation of the flash frequency meter 6 and the broken yarn self-stop inductor 7, facilitating the accurate monitoring of the actual speed of the high-speed rotating motor. At the same time, it can achieve the purpose of observing the static form of the high-speed rotating object and can also play the role of automatically stopping the operation, with high practicality.

[0023] Embodiment Four On the basis of the third embodiment, in order to ensure that when the yarn twisting is completed and the yarn dropping operation is required, the yarn twisting monitoring device can be flipped up without affecting the yarn dropping operation: the driving flipping component includes a servo motor 51, the servo motor 51 is fixedly mounted on the inner surface of the yarn twisting machine body 1, and a driving pulley 511 is fixedly mounted on the output shaft of the servo motor 51, and a driven pulley 512 is arranged on the outer surface of the driving pulley 511, and the outer surface of the driven pulley 512 is rotatably connected to the outer surface of the driving pulley 511 through a belt, and a rotating pulley is fixedly mounted on the central inner surface of the driven pulley 512. A movable shaft 513, the outer surface of the rotating shaft 513 is rotatably connected to the inner wall of the monitoring device base 3; a rotating gear 514 is fixedly installed on the outer surface of the rotating shaft 513, and the rotating gear 514 is rotatably installed on the outer surfaces of both sides of the monitoring device base 3, and an outer surface of one side of the rotating gear 514 is meshed and rotatably engaged with a meshing toothed disc 515, and a center rod 516 is fixedly installed on the central inner surface of the meshing toothed disc 515, and the outer surface of the center rod 516 is rotatably connected to the inner wall of the monitoring device base 3, and the outer surface of the center rod 516 is fixedly connected to the inner wall of the upper end of the monitoring device bracket 4; After the yarn twisting operation is completed, it is allowed to flip the entire monitoring device to a non-working position at the end of the yarn twisting operation to avoid interfering with the yarn dropping operation. Specifically, the servo motor 51 is controlled to work, and its output shaft rotates to drive the active pulley 511 to rotate. Under the rotation connection of the belt, the driven pulley 512 rotates synchronously, and then drives the rotating shaft 513 to rotate. The rotation of the rotating shaft 513 drives the rotating gear 514 to rotate. When the tooth surfaces are adapted to each other, the meshing toothed disc 515 meshes and rotates with the outer surface of the rotating gear 514. The flipping angle of the monitoring device bracket 4 is controlled according to the rotation amplitude of the servo motor 51. In this way, the overall flipping operation of the monitoring device bracket 4 is facilitated to avoid affecting the yarn dropping operation.

[0024] Embodiment 5 On the basis of the fourth embodiment, in order to realize the protection of the monitoring device as a whole during the up and down flipping process: the protection component includes a double-ear tension spring 52 and a shock-absorbing rubber pad 53, the shock-absorbing rubber pad 53 is fixedly mounted on the inner surface of the monitoring device base 3, and the outer surface of the shock-absorbing rubber pad 53 is movably abutted against the outer surface of the monitoring device bracket 4, one end of the double-ear tension spring 52 is rotatably connected to the lower surface of the monitoring device base 3, and the other end of the double-ear tension spring 52 is hinged to the upper outer surface of the monitoring device bracket 4; A shock-absorbing rubber pad 53 is installed on the inner side of the monitoring device base 3 to provide a buffering effect for the entire monitoring device bracket 4 that is flipped up and down, so as to reduce the vibration and noise generated by the monitoring device when it is flipped up and down or when the equipment is running, protect the equipment and improve the monitoring accuracy. In conjunction with the setting of the double-ear tension spring 52, a dynamic stability enhancement structure is introduced at the connection between the monitoring device base 3 and the monitoring device bracket 4. When the bracket is flipped up, the double-ear tension spring 52 provides a pulling force to prevent the monitoring device bracket 4 from falling down due to gravity, thereby maintaining the stability of the monitoring device, and can provide additional support and stability during the flipping process to prevent shaking caused by sudden acceleration or deceleration, thereby further improving the stability of the monitoring device.

[0025] In actual use, first, the glass fiber is twisted and yarn is put on. During the twisting process of the yarn twisting machine body 1, a monitoring device is added. Before the yarn twisting operation, the flash frequency meter 6 and the yarn break automatic stop sensor 7 are installed. The frequency of each flash frequency meter 6 is synchronized with the frequency of the yarn twisting spindle of the yarn twisting machine body 1. A start switch of the flash frequency meter is added to the control panel. When the personnel patrol, the switch is turned on and the flash frequency meter works. After the personnel leave, the switch can be turned off and the flash frequency meter is turned off. The winding state of the yarn can be monitored through the characteristics of the flash frequency meter, and the turning on and off of the flash frequency meter does not affect the normal use of the yarn break automatic stop sensor 7. The flash frequency meter 6 and the yarn break automatic stop sensor 7 are respectively installed on one side of the two sets of U-shaped seats 91. Subsequently, the other side of the U-shaped seat 91 is in contact with the outer side surface of the monitoring device bracket 4. At this time, the turning handle 92 is manually grasped and rotated in a clockwise direction. At this time, the connecting gear cylinder 921 rotates synchronously, and the meshing gear rod 1 922 and the meshing gear rod 2 923 move relative to each other on both sides under the state of matching teeth. Under the continuous rotation of the turning handle 92, the rounded plug-in terminal 924 connected to the outer end of the meshing gear rod 1 922 and the meshing gear rod 2 923 is respectively passed through the inner side of the limiting hole groove 912 provided on the side support plate 911. At this time, the meshing gear rod 1 922 and the meshing gear rod 2 923 complete the locking between the side support plate 911; after the turning handle 92 is rotated, the meshing gear rod 1 922 and the meshing gear rod 2 923 are inserted into the limiting hole groove 912 When the inner side of the positioning hole groove 912 is locked, during the rotation of the turning handle 92, the mounting groove plate 103 on the inner side of the outer ring 101 is evenly distributed, and the soft abutting spring block 1031 installed on the inner side thereof produces a certain abutment under the action of the rotation of the outer turning handle 92, thereby providing a certain resistance to the turning handle 92, and through its elastic force, it will not affect the rotation of the turning handle 92, and when the soft abutting spring block 1031 is squeezed by an external force, a certain elastic deformation is produced, and at this time, the elastic push pieces 1033 on both sides are compressed synchronously, and when the operator releases the turning handle 92 and stops rotating, the soft abutting spring block 1031 and the elastic push piece 1033 at this time produce a reverse elastic force, thereby restricting the turning handle 92 and preventing the turning handle 92 from rotating when not in use The monitoring device 510 can be turned over to the non-working position when in use; after the yarn twisting operation is completed, the entire monitoring device is allowed to be flipped over to the non-working position when the yarn twisting operation is completed to avoid interfering with the yarn dropping operation. Specifically, the servo motor 51 is controlled to work, and its output shaft rotates to drive the active pulley 511 to rotate. Under the rotation connection of the belt, the driven pulley 512 rotates synchronously, and then drives the rotating shaft 513 to rotate. The rotation of the rotating shaft 513 drives the rotating gear 514 to rotate. When the tooth surfaces are adapted to each other, the meshing toothed disc 515 meshes and rotates with the outer surface of the rotating gear 514. The flipping angle of the monitoring device bracket 4 is controlled according to the rotation amplitude of the servo motor 51. In this way, the overall flipping operation of the monitoring device bracket 4 is facilitated to avoid affecting the yarn dropping operation.
