Description

Technical Field

[0001] This utility model relates to the field of texturing machine technology, and more specifically, to a lateral box lifting force adjustment system based on pressure feedback. Background Technology

[0002] The pressure feedback traverse box lifting force adjustment system is a key control system in textile texturing machines. It is mainly used to precisely adjust the lifting force of the guide yarn traverse device to ensure that the yarn tension is uniform and stable during the winding process.

[0003] The pressure feedback-based traverse box lifting force adjustment system mainly collects the pressure value between the yarn guide at the top of the traverse box and the yarn through a pressure sensor. The yarn tension is determined based on the pressure value, and the lifting force is adjusted by driving the yarn guide to rise and fall, thereby controlling the yarn tension. This allows for flexible control of the yarn tension. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] To enable flexible control of yarn tension, this solution provides Example 1:

[0024] Please see Figures 1-5 In this utility model: a pressure feedback-based lateral box lifting force adjustment system includes a lateral box body 1, a base 2 fixedly connected to the top of the lateral box body 1, a groove 3 opened at the bottom of the base 2, a motor 4 fixedly connected to the inner wall of the groove 3, a lead screw 5 rotatably connected to the inner bottom wall of the base 2, two limit rods 6 fixedly connected to the inner bottom wall of the base 2, a lifting block 7 threadedly connected to the lead screw 5, the bottom of the lifting block 7 respectively fitted onto the two limit rods 6 and slidably connected to them, a pressure sensor 8 fixedly connected to the top of the lifting block 7, a mounting base 9 fixedly connected to the top of the pressure sensor 8, a wire guide 10 provided on the top of the mounting base 9, a locking mechanism 11 provided on the top of the mounting base 9, a controller 12, a threshold module 13 and a comparison module 14 fixedly connected to the top of the lateral box body 1, the output ends of the pressure sensor 8 and the threshold module 13 are signal connected to the comparison module 14, the output end of the comparison module 14 is signal connected to the controller 12, and the output end of the controller 12 is signal connected to the motor 4.

[0025] In this invention, the yarn slides on the top of the yarn guide 10. During the sliding process, the tension of the yarn will generate a certain pressure on the yarn guide 10. The yarn guide 10 will transmit the pressure to the pressure sensor 8 through the mounting base 9. The pressure sensor 8 will detect the pressure value generated by the yarn on the yarn guide 10, thereby realizing the pressure value generated by the yarn tension on the yarn guide 10.

[0026] The threshold module 13 stores a maximum threshold and a minimum threshold. The maximum threshold is the value detected by the pressure sensor 8 under the maximum tension of the yarn under normal working conditions, and the minimum threshold is the value detected by the pressure sensor 8 under the minimum tension of the yarn under normal working conditions.

[0027] In actual operation, the maximum and minimum thresholds of the threshold module 13 are adjusted according to the type of yarn. Then, the pressure value detected by the pressure sensor 8 is sent to the comparison module 14, which compares the detected value with the maximum and minimum thresholds respectively.

[0028] When the yarn tension is too high, the comparison module 14 compares the detected pressure value with the maximum threshold value in the threshold module 13. At this time, the comparison module 14 will send an excessive tension signal to the controller 12.

[0029] When the yarn tension is too low, the comparison module 14 compares the detected pressure value and finds that it is less than the minimum threshold in the threshold module 13. At this time, the comparison module 14 will send a tension too low signal to the controller 12.

[0030] When the yarn tension is normal, the detected pressure value will be between the maximum and minimum thresholds, and the comparison module 14 will not generate a signal, thus maintaining the stable operation of the device.

[0031] After receiving a signal of excessive tension, the controller 12 will start the motor 4. The motor 4 will drive the lead screw 5 to rotate. The lead screw 5 is threadedly connected to the lifting block 7. When the motor 4 starts, it will drive the lifting block 7 to descend along the two limit rods 6. At this time, the height of the yarn guide 10 will decrease, thereby reducing the lifting force and reducing the yarn tension.

[0032] After receiving a signal that the tension is too low, the controller 12 will drive the motor 4 in the reverse direction. The motor 4 will drive the lead screw 5 to rotate in the reverse direction, the lifting block 7 will rise, and the height of the yarn guide 10 will increase, thereby increasing the lifting force and increasing the yarn tension.

[0033] Different yarns use different guides 10. To facilitate the replacement of the guides 10, this solution provides an embodiment two:

[0034] Please see Figure 3 The locking mechanism 11 includes two vertical plates 111, the bottom of which is fixedly connected to the mounting base 9. Each of the two vertical plates 111 has a locking rod 112 threaded through it. The bottom bracket of the wire guide 10 has locking holes 113 on both sides that are adapted to the locking rod 112.

[0035] In this utility model, the locking rod 112 cooperates with the locking hole 113 on the bottom bracket of the wire guide 10 to connect the wire guide 10 to the mounting base 9. When the wire guide 10 needs to be replaced, the locking rod 112 is rotated until the locking rod 112 is pulled out from the locking hole 113. At this time, the wire guide 10 will lose its lock, and the wire guide 10 can be replaced. The process is very convenient and quick, effectively improving the practicality of the device.

[0036] The yarn guide 10 generates heat during prolonged contact with the yarn, which is then transferred to the surface of the mounting base 9. This increased temperature of the mounting base 9 affects the detection performance of the pressure sensor 8. To address this issue, this solution provides Embodiment 3:

[0037] Please see Figure 3 and 2 The mounting base 9 has equidistant heat dissipation grooves 15 on its top, and the heat dissipation grooves 15 are V-shaped. The mounting base 9 is a ceramic pad layer, and the outer side of the base 2 has two through holes 16.

[0038] In this utility model, the heat dissipation groove 15 on the top of the mounting base 9 can reduce the contact area with the wire guide 10, thereby reducing heat conduction. At the same time, the gaps in the heat dissipation groove 15 can be used for heat dissipation. Moreover, the mounting base 9 is a ceramic gasket, which can effectively reduce heat conduction, thereby reducing the impact of heat on the pressure sensor 8.

[0039] The two through holes 16 made in the base 2 and the magnetic yoke can be used to expel air and improve the smoothness of the up and down movement of the lifting block 7.

[0040] Please see Figure 1 and 5 The top of the transverse box body 1 is fixedly connected to an abnormality recording module 17 and an alarm 18. The input end of the abnormality recording module 17 is connected to the comparison module 14, and the output end of the abnormality recording module 17 is connected to the alarm 18.

[0041] In this invention, when the comparison module 14 detects that the received pressure value exceeds or falls below the threshold, the comparison module 14 sends a signal to the anomaly recording module 17, which records the anomaly and activates the alarm 18. The alarm is activated until the pressure is between the maximum and minimum thresholds, at which point the anomaly recording module 17 deactivates the alarm 18, thus serving as an auxiliary reminder to the worker of the working status of the wire guide 10.

[0042] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
