[0046] In actual use, the mounting support 41 inside the drive control structure 3 limits the installation of the motor 40. At this time, the motor 40 is started by control, driving the driving wheel 38 to rotate. The driving wheel 38 is provided with the synchronous belt 39, which is driven to rotate by the driving wheel 38, driving the synchronous belt 39 to rotate. The front end of the synchronous belt 39 is connected with the driven wheel 37, which can be driven to rotate, helping to transmit power.

[0047] The second toothed disc 20 is meshingly connected with the first toothed disc 16 and can drive the worm gear 17 through the worm 36. The meshing connection between the second toothed disc 20 and the first toothed disc 16 can drive the first toothed disc 16 to rotate when the worm gear 17 rotates, thereby realizing the driving task of the second toothed disc 20 and driving the driven transmission wheel 22 at the lower end of the second toothed disc 20 to rotate, cooperating with the rotation of the driving transmission wheel 19 to realize the transmission and arrangement of the core-spun yarn.

[0048] The docking rod 28 is sleeved on the upper part of the first toothed disc 16, and the bearing disc 27 is rotatably arranged opposite to the first toothed disc 16.

[0049] The driving transmission wheel 19 and the driven transmission wheel 22 are correspondingly arranged. The gap between the driving transmission wheel 19 and the driven transmission wheel 22 can be adjusted. Through the pushing of the hydraulic oil cylinder 23, the position of the driven transmission wheel 22 can be changed, thereby adjusting the gap between the driving transmission wheel 19 and the driven transmission wheel 22, so that the driving transmission wheel 19 and the driven transmission wheel 22 can conduct with the diameter of the core-spun yarn, helping to perform the cooperative regulation and control work.

[0050] The bottom of the feeding production structure 1 is fixedly connected with a first mounting plate 5, the center of the first mounting plate 5 is fixedly provided with a feeding inlet pipe 4, the lower end of the first mounting plate 5 is fixedly connected with a supporting bottom plate 6, the side away from the first mounting plate 5 of the supporting bottom plate 6 is fixedly connected with a second mounting plate 7, and the center of the second mounting plate 7 is fixedly provided with a feeding outlet pipe 8.

[0051] In use, the user combines the feeding production structure 1, the metering structure 2, the driving control structure 3, the feeding inlet pipe 4, the first mounting plate 5, the supporting bottom plate 6, the second mounting plate 7 and the feeding outlet pipe 8 as a whole, and the core-spun yarn enters through the feeding inlet pipe 4.

[0052] At this time, the driving control structure 3 can work, the mounting support 41 in the driving control structure 3 limits the installation of the motor 40, at this time, the motor 40 is started through control, drives the driving wheel 38 to rotate, at this time, the driving wheel 38 is provided with a synchronous belt 39, which is driven to rotate by the rotation of the driving wheel 38, the front end of the synchronous belt 39 is connected with the driven wheel 37, which can be driven to rotate, helping to transmit power, the front end of the driven wheel 37 is fixedly connected with the worm 36, which is driven to rotate by the rotation of the driven wheel 37, and the other end of the worm 36 is limited by the positioning end frame 34 and the positioning shaft frame 35, the worm 36 can rotate on the positioning shaft frame 35, and can drive the worm gear 17 to rotate synchronously by the rotation of the worm 36, the upper part of the worm gear 17 is fixed with the first tooth disc 16, the lower part is fixed with the driving transmission wheel 19, and the first adapter bearing ring 18 at the center position plays a supporting role, so that the first tooth disc 16, the worm gear 17 and the driving transmission wheel 19 can rotate on the first adapter bearing ring 18, the rotation of the worm gear 17 drives the first tooth disc 16 and the driving transmission wheel 19 to rotate synchronously, at this time, the user adjusts the position of the second tooth disc 20 through the hydraulic oil cylinder 23, the hydraulic oil cylinder 23 is controlled to extend and retract, driving the push derivation seat 24 to move on the first grid frame 12, so as to change the positions of the second tooth disc 20, the second adapter bearing ring 21, the driven transmission wheel 22 and the push derivation seat 24, at this time, the second tooth disc 20 is in contact with the first tooth disc 16, and the rotation of the first tooth disc 16 can drive the second tooth disc 20 to rotate in the opposite direction, while the second tooth disc 20 drives the driven transmission wheel 22 at the lower end to rotate synchronously, at this time, the driving transmission wheel 19 and the driven transmission wheel 22 rotate in opposite directions, driving the core-spun yarn at the center position to be transmitted.

[0053] After that, the core yarn is conducted to the first feeder 9 through the combined connecting frame 10, and continues to be conducted and finally transmitted through the feeding outlet pipe 8 on the second mounting plate 7 to help the production process, and when the first toothed disc 16 rotates, the rotation speed sensor 26 is fixed on the upper part of the matching bearing disc 27, and the lower end probe position of the rotation speed sensor 26 penetrates through the matching bearing disc 27 and the first toothed disc 16, which is used for the detection of the rotation speed of the first toothed disc 16. The rotation speed sensor 26 at the upper position can monitor and calculate the rotation speed of the first toothed disc 16. The rotation speed sensor 26 can detect the number of rotations per unit time when the first toothed disc 16 rotates through the photoelectric effect, so as to detect the speed. Through calculation and measurement, the amount of conduction can be calculated and processed, and the position of the rotation speed sensor 26 and the matching bearing disc 27 can be adjusted.

[0054] When speed calculation is not required, the user can manually adjust to cancel the contact between the butt plug rod 28 and the first toothed disc 16, and press the matching bearing disc 27 by pushing it with the user. The matching bearing disc 27, the butt plug rod 28 and the first hinged rod 29 are installed in position and set in position. When the matching bearing disc 27 moves backward, the upper butt plug rod 28 and the first hinged rod 29 can move backward to push the hinged rod frame 30, so that the hinged rod frame 30 pushes the adaptive displacement seat 32 to move on the limiting slide rod 31 through the second hinged rod 33, changes the distance between the symmetrically arranged adaptive displacement seats 32, and adjusts the position of the front and rear ends of the matching bearing disc 27. When the device is not counted, it can prevent false touch. Through the adjustment of the position, the space above can be expanded to facilitate personnel observation and complete the work.

[0055] Based on example 1, as shown in Figure 9 The side end of the first mounting plate 5 is fixedly connected with a combined partition 42, the center of the combined partition 42 is rotatably connected with a threaded adjusting rod 43, the upper end of the threaded adjusting rod 43 is threadedly connected with a threaded transmission frame 44, and the middle part of the threaded transmission frame 44 is fixedly connected with a butt cone pipe 45.

[0056] In the implementation of the embodiment, the combined partition 42 is connected at the side end of the first mounting plate 5, and the threaded adjusting rod 43 is rotatably connected to the combined partition 42. The threaded adjusting rod 43 can change the position of the threaded transmission frame 44 by rotating adjustment. The threaded transmission frame 44 can cooperate with the rotation of the threaded adjusting rod 43 to change the position, so as to adjust the position of the butt cone pipe 45. The core yarn can enter the feeding inlet pipe 4 and the first mounting plate 5 through the butt cone pipe 45. When the core yarn reaches the butt cone pipe 45, the impurities and dust on the upper part of the core yarn can be treated. Example 2

[0057] It is found in the process used in Embodiment 1 that the thickness of the core yarn directly determines the distance between the driving transmission wheel 19 and the driven transmission wheel 22, that is, the thickness of the core yarn determines the extension length of the hydraulic cylinder 23, and the thicker the core yarn, the more material is needed when wrapping the powdered additive layer on the outside of the core yarn, and the more time is needed to wrap the powdered additive layer, which means that the thicker the core yarn, the smaller the conveying amount of the core yarn per unit time, so as to ensure that the powdered additive layer can be smoothly and uniformly wrapped outside the core yarn. Therefore, the conveying feed amount of the core yarn needs to be adjusted according to the thickness of the core yarn. Based on this, the following improvement scheme is proposed in the present application:

[0058] A pressure sensor is fixedly assembled on the outer side wall of the driven transmission wheel 22. The diameter standard of the thickness of the core yarn is D1. Therefore, the standard distance that the driven transmission wheel 22 moves under the driving of the hydraulic cylinder 23 is L1. Therefore, when feeding the core yarn with different diameters, the pressure sensor is always ready to contact the core yarn during the movement of the driven transmission wheel 22 driven by the hydraulic cylinder 23. When the driven transmission wheel 22 contacts the core yarn, the pressure sensor will generate a pressure signal. At this time, the extension length L of the hydraulic cylinder 23 can be detected, and then the extension length L of the hydraulic cylinder 23 is compared with L1. If L is less than L1, it indicates that the diameter of the core yarn is greater than D1. At this time, the controller reduces the speed of the motor 40 to match the core yarn with larger thickness, so as to more uniformly wrap the powdered additive layer on the core yarn. When the motor 40 with larger thickness reduces the speed, the rotating speed of the first toothed disc 16 is indirectly reduced, so as to reduce the transmission speed of the core yarn between the driving transmission wheel 19 and the driven transmission wheel 22. This facilitates the powdered additive layer to be better wrapped on the core yarn, improves the uniformity and wrapping quality of the powdered additive layer, otherwise, the conveying feed amount of the core yarn can be adjusted according to the thickness of the core yarn. Embodiment 3

[0059] It is found in the process used in Embodiment 2 that the softness and hardness of the core yarn will directly affect the distance between the driving transmission wheel 19 and the driven transmission wheel 22, and the core yarn with different softness and hardness will deform during conveying, which easily leads to insufficient friction between the core yarn and the driving transmission wheel 19 and the driven transmission wheel 22, and cannot achieve the purpose of transmission feeding. In addition, when the core yarn is soft, the resilience of the core yarn is different, which leads to different plasticity. Therefore, when the powdered additive layer is wrapped on the outside of the core yarn, the core yarn and the powdered additive layer are not easily pressed and attached, which leads to the separation of the powdered additive layer. Therefore, the softness and hardness of the core yarn will affect the wrapping quality of the powdered additive layer. Based on this, the following improvement scheme is proposed in the present application:

[0060] When the driven transmission wheel 22 and the core yarn contact, the pressure sensor generates a pressure signal, at this time the pressure sensor sends a control signal to the controller to start feeding the yarn, at this time it indicates that the core yarn is in a transmission state, at this time the core yarn is transmitted by the friction between the driving transmission wheel 19 and the driven transmission wheel 22, and the transmission speed of the core yarn is the same as the rotation speed of the driving transmission wheel 19 in principle. When the transmission speed of the core yarn is less than the rotation speed of the driving transmission wheel 19, it indicates that there is a transmission speed difference between the driving transmission wheel 19 and the core yarn, which indicates that the softness of the outer side of the core yarn causes insufficient friction between the driving transmission wheel 19 and the core yarn, thereby affecting the normal transmission of the core yarn. At this time, the controller controls the hydraulic cylinder 23 to extend to reduce the distance between the driving transmission wheel 19 and the driven transmission wheel 22, thereby increasing the friction between the core yarn and the driving transmission wheel 19 and the driven transmission wheel 22, until the rotation speed of the driving transmission wheel 19 and the transmission speed of the core yarn are the same. At this time, the extension length of the hydraulic cylinder 23 is the softness of the core yarn. In this way, the speed ratio between the transmission speed of the core yarn and the rotation speed of the driving transmission wheel 19 is used to control the extension length of the hydraulic cylinder 23, and the extension length of the hydraulic cylinder 23 is used to detect the softness of the core yarn.

[0061] It is worth mentioning that two groups of first feeders 9 and second feeders 10 are symmetrically arranged in the application file, and there are four groups of driving transmission wheels 19 and driven transmission wheels 22 for conveying the core yarn. In actual use, the four groups of driving transmission wheels 19 and driven transmission wheels 22 are used to realize synchronous conveying of the core yarn, and the four groups of hydraulic cylinders 23 are extended synchronously until the pressure sensor generates a pressure signal. At this time, the extension length of the hydraulic cylinder 23 is recorded as L0, indicating that the core yarn is clamped between the driving transmission wheel 19 and the driven transmission wheel 22. During the conveying process, when the core yarn passes through the first group of driving transmission wheel 19 and driven transmission wheel 22, the hydraulic cylinder 23 at this position continues to extend at a constant speed. In the process of driving the driving transmission wheel 19 to rotate and drive the driven transmission wheel 22 to rotate, the extrusion force of the driven transmission wheel 22 on the core yarn is gradually increased by the extension of the hydraulic cylinder 23, until the pressure value on the pressure sensor reaches the maximum threshold value, and the time from when the pressure sensor receives the pressure signal to when the maximum threshold value is reached is recorded. Since the extension speed of the hydraulic cylinder 23 is constant, the extension length of the driven transmission wheel 22 driven by the hydraulic cylinder 23 can be intuitively obtained within this time period. At this time, the extension length L1 of the second group of hydraulic cylinders 23 is recorded, that is, the thickness of the compressed core yarn. By detecting the compressible thickness of the core yarn, the compressibility of the core yarn can be determined. Then the core yarn in the conveying process reaches between the second group of driving transmission wheel 19 and driven transmission wheel 22. Since the core yarn has been subjected to extreme extrusion by the first group of driving transmission wheel 19 and driven transmission wheel 22, the core yarn is in a compressed state. The second group of hydraulic cylinders 23 is extended to drive the second group of driven transmission wheels 22 to move until they contact the core yarn. At this time, the extension length L2 of the second group of hydraulic cylinders 23 is recorded. Similarly, the extension length L3 of the third group of hydraulic cylinders 23 and the extension length L4 of the fourth group of hydraulic cylinders 23 are recorded in turn. In this way, the resilience of the core yarn is obtained by L1, L2, L3 and L4, which is:

[0062] When L2, L3 and L4 are the same, it indicates that the resilience of the core-spun yarn is poor, and the resilience range is the difference between L1 and L2; when L1 is greater than L2 and greater than L3 and L4 and L3 and L4 are the same, it indicates that the resilience of the core-spun yarn is relatively good, and the resilience range is the difference between L1 and L3; when L1 is greater than L2, greater than L3, greater than L4 and greater than L0, it indicates that the resilience of the core-spun yarn is good, but it does not indicate that the resilience range of the core-spun yarn reaches the maximum, at this time the controller reduces the speed of the motor 40 to reduce the conveying speed of the core-spun yarn until L3 and L4 are the same, at this time it indicates that the core-spun yarn has reached the maximum resilience after being extruded by the first set of driving and driven transmission wheels 19 and 22 to the third set of driving and driven transmission wheels 19 and 22, at this time the difference between L1 and L3 is the resilience range of the core-spun yarn, if L3 is less than L0 at this time, it indicates that the core-spun yarn cannot fully rebound after being extruded, and the ratio of the difference between L1 and L3 to L0 is the resilience of the core-spun yarn.

[0063] In summary, the first feeder 9 and the second feeder 10 are used to detect the resilience of the core-spun yarn during conveying, and the conveying speed of the motor 40 can be adjusted by feedback to the controller, so as to ensure that the first feeder 9 and the second feeder 10 have high accuracy during resilience detection, and to provide feedback control for the resilience detection of the core-spun yarn, and when the resilience is less than the standard threshold, it indicates that the resilience of the batch of core-spun yarn is unqualified.
