Abstract

The present invention discloses a device for adjusting the draft multiple of a spinning frame, belonging to the technical field of the drafting end of a spinning frame. It includes an assembled base frame, a first driving roller sleeve, a second driving roller sleeve, and a lubricant twisting mechanism, which fills the second driving roller sleeves on both sides at this position with lubricant for fine yarn lubrication and twisting operations. Through the coordinated execution mechanism of dynamic lubrication and draft multiple adjustment, the defect that the shutdown adjustment and lubrication process of traditional equipment are separated is solved. The lubricant twisting mechanism and the driving roller are integrally designed, and the servo motor is used to synchronously drive the mixing mechanism and the twisting rod, so that the lubricant can penetrate to the surface of the fiber in real time during the drafting process. Among them, the combination of heat generation by the friction coating and the flow rate control of multiple leakage ports realizes the uniform mixing of the lubricant during the conveying process. Without the need for external lubrication equipment, it effectively reduces the yarn breakage rate and significantly improves the flexible switching ability of multi-variety yarn production.

Description

Technical Field

[0001] The present invention relates to the technical field of the drafting end of a spinning frame, and more specifically, to an adjustable device for the drafting multiple of a spinning frame. Background Art

[0002] The spinning frame is a core device in the spinning process. It uniformly draws and twists the thick fiber sliver through a drafting mechanism to finally form a fine yarn that meets the requirements. During the drafting process, the rotational speed difference between the front roller and the rear roller determines the drafting multiple, and this parameter directly affects the yarn count and the quality stability. In traditional spinning frames, the adjustment of the drafting multiple usually relies on a fixed combination of gear sets or pulley transmission ratios. It is necessary to stop the machine to replace gears or adjust the transmission structure, resulting in a reduction in production efficiency and difficulty in meeting the flexible production requirements of multi-variety and small-batch yarns.

[0003] Although existing adjustable devices for the drafting multiple have made improvements through mechanical structures, such as adjustable gearboxes, to achieve a certain degree of dynamic adjustment, they lack coordinated optimization of the friction problem between the rollers and the fiber sliver. Due to the long-term high-speed operation of the roller surface and the lack of continuous lubrication, the fiber sliver is prone to generate static electricity, flyers, and broken yarns during the drafting process, especially when processing high-count yarns or synthetic fibers.

[0004] Although in the prior art, the above problems can be improved by lubricating the fiber sliver through external oiling equipment or manual methods, such methods require additional processes, resulting in an increase in equipment complexity, an extension of downtime, and difficulty in ensuring lubrication uniformity, and cannot reduce friction losses while improving the adjustment efficiency. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide an adjustable device for the drafting multiple of a spinning frame, aiming to solve the above technical problems.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] An adjustable device for the drafting multiple of a spinning frame includes an assembled base frame. On both sides of the surface of the assembled base frame, a number of groups of first driving roller sleeves are arranged. And an outward-turning sleeve frame is movably hinged on the upper surface of the assembled base frame. At positions on both sides of the surface of the outward-turning sleeve frame opposite to the first driving roller sleeves, second driving roller sleeves are arranged. And at the position of the second driving roller sleeve in the exact middle of the upper surface of the outward-turning sleeve frame, a lubricant twisting mechanism is also arranged to pour lubricant into the second driving roller sleeves on both sides at this position for fine yarn lubrication and twisting operations.

[0008] Above the lubricant twisting mechanism, there is a lubricant mixing mechanism for replenishing lubricant to the lubricant twisting mechanism. The lubricant twisting mechanism includes a disc sleeve, a first extended twisting rod and a second extended twisting rod which are respectively movably arranged on both sides of the disc sleeve, and the first extended twisting rod and the second extended twisting rod are respectively aligned with the first driving roller sleeve on the same side.

[0009] Among them, at the central axis position of the top of the lubricant mixing mechanism, a servo motor is fixedly installed. The lubricant mixing mechanism includes a liquid storage cylinder fixedly installed on the upper side of the disc sleeve through a bracket. Inside the liquid storage cylinder, a second shaft rod fixedly connected to the output end of the servo motor is movably installed. At the bottom of the second shaft rod, an auxiliary reagent self-supplementing mechanism is also configured to control the auxiliary reagent stored in the auxiliary reagent self-supplementing mechanism to dissolve in the lubricant through the driving action of the output end of the servo motor for deep lubrication and twisting operation of the fine yarn.

[0010] As a further scheme of the present invention: at the central position of the inner circle of the disc sleeve, a socket bracket is fixedly installed. The socket position of the socket bracket is a cavity structure, and a cavity conduit is movably installed through the cavity structure. The cavity conduit communicates with the socket cavity of the socket bracket. On both sides of the cavity conduit, a first extended twisting rod and a second extended twisting rod that can movably penetrate the side wall of the disc sleeve are respectively fixedly installed. On the outer ends of the first extended twisting rod and the second extended twisting rod, twisting socket heads are fixedly installed. An adsorption coating is sleeved on the outer surface of each twisting socket head. And at the inner central axis position of each twisting socket head, a liquid guiding inner cavity channel for supplying liquid to the adsorption coating is opened. And micro-sized through openings communicating with the liquid guiding inner cavity channels and the cavity conduit on the same side are opened inside the first extended twisting rod and the second extended twisting rod.

[0011] As a further scheme of the present invention: the lubricant twisting mechanism further includes a first shaft rod movably installed at the central position of the upper surface of the disc sleeve. And at the end of the first shaft rod extending into the disc sleeve, a second gear disc is fixedly connected. On the surface of the second extended twisting rod, a first gear disc corresponding to meshing with the second gear disc is fixedly installed. On the outer surface of the socket bracket, two first drain hoses communicating with the socket cavity are also fixedly installed. And the extending ends of the first drain hoses bypass the second gear disc and penetrate outwards from the top of the disc sleeve.

[0012] As a further solution of the present invention: The lubricant mixing mechanism further includes a circular sleeve cavity fixedly connected to the bottom of the second shaft rod. A number of concentric circular cavities coaxial with the circular sleeve cavity are fixedly installed at the bottom of the circular sleeve cavity, and there are gaps between each group of circular cavities. A first friction coating is fixedly installed on the outer circular surface of each group of circular cavities. A number of first leakage openings are provided on the upper surface of each group of circular cavities, and four second leakage openings separated by 90 degrees are provided on the lower surface of each group of circular cavities. A third shaft rod is also fixedly connected to the center position at the bottom of the circular sleeve cavity.

[0013] As a further solution of the present invention: The bottom of the liquid storage cylinder is fixedly connected with a multi-ring chassis. The multi-ring chassis is an inverted disk structure composed of multiple concentric rings. The multi-ring chassis is fitted with the circular cavities at the bottom of the circular sleeve cavity one by one. A second friction coating corresponding to and fitting the first friction coating on the outer surface of the circular cavity is also fixedly installed on the ring surface of the multi-ring chassis. The bottom of the multi-ring chassis is fixedly connected with a funnel bottom bin. Four third leakage openings are provided on the bottom surface of each ring grid of the multi-ring chassis, and each third leakage opening is separated by 90 degrees. A through-hole conduit through which the third shaft rod can penetrate into the funnel bottom bin is also fixedly installed at the center position of the multi-ring chassis.

[0014] As a further solution of the present invention: The auxiliary reagent self-supplementing mechanism includes a sealing disk fixedly installed at the bottom of the third shaft rod penetrating into the funnel bottom bin. The sealing disk is closely attached to the bottom of the multi-ring chassis. A bidirectional threaded rod is fixedly connected to the center position at the bottom of the sealing disk. A threaded sleeve is meshingly installed on the bidirectional threaded rod. A limiting sleeve housing is also fixedly connected to the bottom of the multi-ring chassis. A convex block fitted into the limiting sleeve housing is fixedly connected to the side surface of the threaded sleeve.

[0015] As a further solution of the present invention: The auxiliary reagent self-supplementing mechanism further includes four sector-shaped liquid storage cavities fixedly installed at the center position of the inner bottom of the funnel bottom bin. A self-sealing rubber spray nozzle is fixedly installed on the outer circular surface of each group of sector-shaped liquid storage cavities. The self-sealing rubber spray nozzle is a structure of four closely-fitting sector-shaped sealing sheets. An outer bent rod that is hermetically inserted into the sector-shaped liquid storage cavity is fixedly connected to the bottom surface of the threaded sleeve at a position corresponding to each group of sector-shaped liquid storage cavities. A piston plate is fixedly installed on each outer bent rod extending into the sector-shaped liquid storage cavity.

[0016] As a further solution of the present invention: The auxiliary reagent self-supplementing mechanism further includes four liquid supplement conduits hermetically inserted from the bottom of the funnel bottom bin, and each inserted liquid supplement conduit is connected to the fan-shaped liquid storage cavity on the same side. The bottom of the bidirectional threaded rod is also fixedly connected with a fourth shaft rod, and a fourth leak port for the fourth shaft rod to hermetically pass through is also opened at the center position of the bottom of the funnel bottom bin, and the fourth shaft rod passing through the fourth leak port is fixedly connected to the first shaft rod.

[0017] As a further solution of the present invention: The auxiliary reagent self-supplementing mechanism further includes four groups of auxiliary reagent storage boxes fixedly installed on the outer surface of the liquid storage cylinder, and a second liquid discharge hose is fixedly connected to the bottom of each group of auxiliary reagent storage boxes. The end of the liquid supplement conduit hermetically inserted from the bottom of the funnel bottom bin, which is far away from the fan-shaped liquid storage cavity, is fixedly connected to the second liquid discharge hose on the same side.

[0018] As a further solution of the present invention: Fifth leak ports for communicating with the first liquid discharge hose passing through the upper surface of the disc sleeve are also opened at both side end positions of the bottom of the funnel bottom bin. An open-type stirring frame is fixedly connected to the outer surface of the second shaft rod. A fiber filament winding module is fixedly installed on the outside of the assembly base frame.

[0019] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects:

[0020] (1) Through the collaborative execution mechanism of dynamic lubrication and draw ratio adjustment, the defect that the traditional equipment stops for adjustment and the lubrication process are separated is solved. The lubricant twisting mechanism and the driving roller are integrally designed, and the servo motor is used to synchronously drive the mixing mechanism and the twisting rod, so that the lubricant can penetrate to the fiber surface in real time during the drawing process. The combination of heat generation by the friction coating and the flow rate control of multiple leak ports realizes the uniform mixing of the lubricant during the transportation process. Without an external lubrication device, it effectively reduces the yarn breakage rate and significantly improves the flexible switching ability of multi-variety yarn production.

[0021] (2) Through the linkage design of the bidirectional threaded rod and the fan-shaped liquid storage cavity, combined with the reciprocating extrusion action of the piston plate, the quantitative release of four types of auxiliary reagents is realized. The device can automatically adjust the mixing ratio of antistatic agents, heat-resistant agents, etc. according to the material characteristics of the yarn, further expanding the applicability of synthetic fibers and natural fibers, enabling the lubrication equipment to lubricate lubricating reagents and auxiliary reagents on the premise of providing lubrication, and adapting to more complex processing environments, and solving the concentration gradient problem existing in traditional manual proportioning.

[0022] (3) Through energy recovery and process intensification design, a sustainable closed-loop process system is formed. The mechanical energy generated by the rotation of the roller is used to drive the friction heat generation module, stably controlling the lubricant temperature within a certain optimal active range, and being more energy-efficient compared to the electric heating method. The sequential matching design of the circular cavity and the multi-leakage port structure extends the residence time of the lubricant in the system, ensuring the full activation of the additives.

[0041] As shown in the figure, in order to clearly show the structure of the embodiments of the present invention, specific structures and devices are marked in the figure. However, this is only for schematic purposes and is not intended to limit the present invention to this specific structure, device, and environment. Those of ordinary skill in the art can adjust or modify these devices and environments according to specific needs. Detailed Embodiment

[0042] The following describes in detail a device for adjusting the draft multiple of a spinning frame provided by the present invention with reference to the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. Those skilled in the art in some well - known technical fields can also implement them in other alternative ways; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.

[0043] As Figures 1 to 10As shown in the figure, an adjustable drafting multiple device for a spinning frame according to an embodiment of the present invention includes an assembled base frame 1. On both sides of the surface of the assembled base frame 1, a plurality of groups of first driving roller sleeves 2 are arranged. And an outward-turning sleeve frame 4 is movably hinged on the upper surface of the assembled base frame 1. At positions on both sides of the surface of the outward-turning sleeve frame 4 facing the first driving roller sleeves 2, second driving roller sleeves 5 are arranged. And at the position of the second driving roller sleeve 5 in the middle of the upper surface of the outward-turning sleeve frame 4, a lubricant twisting mechanism 6 is further arranged to pour lubricant into the second driving roller sleeves 5 on both sides at this position for lubricant twisting operation of the spun yarn;

[0044] Above the lubricant twisting mechanism 6, a lubricant mixing mechanism 7 for supplementing lubricant to the lubricant twisting mechanism 6 is arranged. The lubricant twisting mechanism 6 includes a disc sleeve 61 and a first outward-extending twisting rod 64 and a second outward-extending twisting rod 65 which are respectively movably arranged on both sides of the disc sleeve 61. And the first outward-extending twisting rod 64 and the second outward-extending twisting rod 65 are respectively aligned with the first driving roller sleeves 2 on the same side;

[0045] Among them, a servo motor 19 is fixedly installed at the central position of the top of the lubricant mixing mechanism 7. The lubricant mixing mechanism 7 includes a liquid storage cylinder 71 fixedly installed on the upper side of the disc sleeve 61 through a bracket. Inside the liquid storage cylinder 71, a second shaft rod 72 fixedly connected to the output end of the servo motor 19 is movably installed. At the bottom of the second shaft rod 72, an auxiliary reagent self-supplementing mechanism 15 is further arranged to control the auxiliary reagent stored in the auxiliary reagent self-supplementing mechanism 15 to dissolve in the lubricant through the driving action of the output end of the servo motor 19 for deep lubricant twisting operation of the spun yarn.

[0046] To solve the problem that the drafting end of the existing spinning frame lacks the collaborative optimization of the friction problem between the rollers and the fiber strip, the above technical solution is adopted to solve it. The above technical solution mainly consists of an assembled base frame 1, a first driving roller sleeve 2, an outward-turning sleeve frame 4, a second driving roller sleeve 5, a lubricant twisting mechanism 6, and a lubricant mixing mechanism 7. The assembled base frame 1 is the driving base device of the existing spinning frame and is the basic support part of the entire spinning frame. It not only bears the weight of all mechanical components but also ensures the stability of the machine during operation. Its output end is arranged inside the housing and is used to drive the first driving roller sleeve 2 on both output shafts. Both the first driving roller sleeve 2 and the second driving roller sleeve 5 are roller rod structures in the existing technology. The system is responsible for drafting the roving. It is made of strong and durable metal materials and has sufficient strength and rigidity to resist the vibration generated by high-speed operation. It is divided into a front roller, a middle roller, and a rear roller. The front roller outputs the sliver after the final drafting and feeds it into the twisting area. The middle roller participates in the drafting process in the intermediate stage, helps to adjust the fiber arrangement, participates in the drafting process in the intermediate stage, helps to adjust the fiber arrangement, cooperates with the feeding mechanism, and controls the speed of the roving entering the drafting area. The so-called feeding mechanism is a structure in the shape of a trumpet mouth for feeding fibers and belongs to the double-in single-out trumpet mouth in the existing technology. The overall structure has a technical transformation with an extra-large diameter of 32.5 mm at the front apron position of the roving frame and an extra-large diameter of 34 mm at the front apron position of the spinning frame. The configured outward-turning sleeve frame 4 also belongs to the inherent structure hinged on the assembled base frame 1 in the existing technology and is used to adjust the interval between the upper and lower groups of the first driving roller sleeve 2 and the second driving roller sleeve 5;

[0047] The configured lubricant twisting mechanism 6 as a whole is a structure installed on the everted sleeve frame 4. The roller rod structures extending from the output ends on both sides of the lubricant twisting mechanism 6 replace the middle roller structure in the prior art to avoid interfering with the working characteristics of the front roller and the rear roller. The so-called lubricant mixing mechanism 7 is arranged above the lubricant twisting mechanism 6 and is a mechanism for supplementing lubricant to the lubricant twisting mechanism 6. Specifically, the lubricant twisting mechanism 6 includes a disc sleeve 61 and a first externally extending twisting rod 64 and a second externally extending twisting rod 65 respectively movably arranged on both sides of the disc sleeve 61, which is used to replace the middle roller structure in the prior art. Among them, a servo motor 19 is fixedly installed at the central axis position at the top of the lubricant mixing mechanism 7. The so-called servo motor 19 is a driving motor structure capable of servo control in the prior art, which provides driving force for the device. A second shaft rod 72 is arranged inside the liquid storage cylinder 71. An auxiliary reagent self-supplementing mechanism 15 is also arranged at the bottom of the second shaft rod 72. During the working process, the auxiliary reagent stored in the auxiliary reagent self-supplementing mechanism 15 can be controlled to dissolve in the lubricant through the driving action of the output end of the servo motor 19, and then the lubricating reagent mixed with the auxiliary reagent is guided to the first externally extending twisting rod 64 and the second externally extending twisting rod 65 through the conveying action of the lubricant twisting mechanism 6 to perform deep lubrication and twisting operations on the fine yarn, so as to solve the problem of lack of coordinated optimization of the friction problem between the roller and the fiber strip in the prior art structure.

[0048] As Figures 1 through 10 shown, a socket support 62 is fixedly installed at the central position inside the disc sleeve 61. The socket position of the socket support 62 is a cavity structure, and a cavity conduit 63 is movably installed through the cavity structure. The cavity conduit 63 communicates with the socket cavity of the socket support 62. A first externally extending twisting rod 64 and a second externally extending twisting rod 65 that can movably penetrate the side wall of the disc sleeve 61 are respectively fixedly installed on both sides of the cavity conduit 63. Twisting sleeves 66 are fixedly installed on the externally extending ends of the first externally extending twisting rod 64 and the second externally extending twisting rod 65. Adsorption coatings are sleeved on the outer surfaces of the twisting sleeves 66, and a liquid guiding inner cavity channel 68 for supplying liquid to the adsorption coating is opened at the central axis position of each twisting sleeve 66. Micro-sized through openings 67 communicating with the liquid guiding inner cavity channel 68 and the cavity conduit 63 on the same side are opened inside the first externally extending twisting rod 64 and the second externally extending twisting rod 65.

[0049] Among them, the configured socket support 62 is as shown in the attached Figure 10As shown, the interior is a cavity structure for storing the reagent entering, and the cavity catheter 63 movably installed inside is a catheter structure connected in the cavity of the sleeve bracket 62 through a connecting plate. On the one hand, it ensures that the catheter ends output on both sides can rotate synchronously, and on the other hand, it does not affect the reagent in the cavity of the sleeve bracket 62 from entering the catheter, and the first outwardly extending twisting rod 64 and the second outwardly extending twisting rod 65 arranged on both sides of the cavity catheter 63 are provided with miniature openings 67 to transport the reagent entering the cavity of the sleeve bracket 62 from the cavity catheter 63 through the miniature openings 67 to the liquid guiding lumen channel 68, so that the outer surfaces of the first outwardly extending twisting rod 64 and the second outwardly extending twisting rod 65 are soaked with the lubricating reagent.

[0050] like Figures 1 to 10 As shown, the lubricant twisting mechanism 6 also includes a first shaft rod 610 movably mounted at the center position of the upper surface of the disc sleeve 61, and the first shaft rod 610 extends inside the disc sleeve 61. One end is fixedly connected to a second gear plate 611, and the surface of the second extended twisting rod 65 is fixedly mounted with a first gear plate 69 corresponding to the second gear plate 611, and two groups of first drainage hoses 16 communicating with the sleeve cavity are also fixedly mounted on the outer surface of the sleeve bracket 62, and the protruding end of the first drainage hose 16 bypasses the second gear plate 611 and passes out from the top of the disc sleeve 61.

[0051] Among them, the second gear plate 611 arranged inside the disc sleeve 61 is meshed with the first gear plate 69 on the surface of the second extended twisting rod 65. When the first shaft 610 is driven, the second gear plate 611 can drive the first gear plate 69 to rotate synchronously, and then the first extended twisting rod 64 and the second extended twisting rod 65 on both sides can rotate synchronously in the same direction, so that the wetted twisting rod can cooperate with the rotation of the first driving roller sleeve 2 to evenly apply the lubricating agent to the surface of the passing fiber.

[0052] like Figures 1 to 10 As shown, the lubricant mixing mechanism 7 also includes a circular sleeve disc cavity 74 fixedly connected to the bottom of the second shaft rod 72, and a plurality of groups of annular cavities 75 coaxial with the circular sleeve disc cavity 74 are fixedly installed at the bottom of the circular sleeve disc cavity 74, and there are gaps between each group of annular cavities 75, and a first friction coating 78 is fixedly installed on the outer annular surface of each group of annular cavities 75, and a plurality of groups of first leakage openings 76 are opened on the upper surface of each group of annular cavities 75, and four groups of second leakage openings 77 spaced 90 degrees apart are opened on the lower surface of each group of annular cavities 75, and a third shaft rod 79 is also fixedly connected to the center position of the bottom of the circular sleeve disc cavity 74.

[0053] Among them, the circular sleeve cavity 74 configured at the bottom of the second shaft rod 72 and the annular cavity 75 are of an integral structure. The annular cavity 75 is composed of several groups of multi-ring cavities coaxial with the circular sleeve cavity 74, and there is a gap between each group of annular cavities 75. This gap is for fitting with the multi-ring chassis 8, so that the first friction coating 78 on the outer ring surface of each group of annular cavities 75 corresponds to the second friction coating 9 on the ring surface of the multi-ring chassis 8. During the high-speed rotation of the annular cavity 75, the two fitted first friction coating 78 and the second friction coating 9 can generate heat by friction. Also, because several groups of first leakage ports 76 are provided on the upper surface of each group of annular cavities 75, and only four second leakage ports 77 spaced 90 degrees apart are provided on the lower surface of each group of annular cavities 75. Specifically, it means that the openings on the upper side of each group of annular cavities 75 are much larger than the openings on the lower side. As a result, the reagent stored on the upper side of the liquid storage cylinder 71 can smoothly enter the annular cavity 75 through the first leakage ports 76 on the upper side of each group of annular cavities 75, and it is very difficult to discharge from the bottom of the annular cavity 75. By using this flow rate difference, the entering reagent can be stored in each group of annular cavities 75 for a period of time, so that the reagent can be heated in this cavity for a longer time.

[0054] As Figures 1 to 10 shown, the bottom of the liquid storage cylinder 71 is fixedly connected with a multi-ring chassis 8. The multi-ring chassis 8 is an overall concave disc structure composed of multiple groups of concentric rings, and the multi-ring chassis 8 is fitted with the annular cavity 75 at the bottom of the circular sleeve cavity 74 one by one. Also, a second friction coating 9 corresponding to the first friction coating 78 on the outer surface of the annular cavity 75 is fixedly installed on the ring surface of the multi-ring chassis 8. The bottom of the multi-ring chassis 8 is fixedly connected with a funnel bottom bin 12, and four third leakage ports 10 are provided on the bottom surface of each ring grid of the multi-ring chassis 8, and each third leakage port 10 is spaced 90 degrees apart. A through conduit 11 through which the third shaft rod 79 can penetrate into the funnel bottom bin 12 is also fixedly installed at the center position of the multi-ring chassis 8.

[0055] Among them, the configured multi-ring chassis 8 is an overall concave disk structure composed of multiple groups of concentric rings. Setting it as a concave disk structure is for the purpose of fitting the circular cavity 75 on one hand, and on the other hand, to make the upper surface of the fitted circular cavity 75 flush with the bottom surface of the liquid storage cylinder 71, so that the reagent at the bottom of the liquid storage cylinder 71 can be discharged smoothly. Further, four groups of third leakage ports 10 are opened on the bottom surface of each ring grid of the multi-ring chassis 8, and each third leakage port 10 is separated by 90 degrees. The circular cavity 75 is sleeved on the upper surface of the multi-ring chassis 8. Only when the second leakage port 77 opened at the bottom of the circular cavity 75 is aligned with the third leakage port 10, the reagent stored in each cavity of the circular cavity 75 will be discharged, further increasing the residence time of the reagent in the circular cavity 75 and providing a longer heating environment for it.

[0056] As Figures 1 to 10 shown, the auxiliary reagent self-supplementing mechanism 15 includes a sealing disk 151 fixedly installed at the bottom of the third shaft rod 79 penetrating into the bottom bin 12 of the funnel. The sealing disk 151 is integrally closely attached to the bottom of the multi-ring chassis 8. A bidirectional threaded rod 152 is fixedly connected to the center position of the bottom surface of the sealing disk 151. A threaded sleeve disk 154 is meshingly installed on the bidirectional threaded rod 152. A limiting sleeve housing 153 is also fixedly connected to the bottom of the multi-ring chassis 8. A convex block 155 fitted into the limiting sleeve housing 153 is fixedly connected to the side surface of the threaded sleeve disk 154.

[0057] As Figures 1 to 10 shown, the auxiliary reagent self-supplementing mechanism 15 further includes four groups of sector-shaped liquid storage cavities 158 fixedly installed at the center position of the inner bottom of the funnel bottom bin 12. A self-sealing rubber spray nozzle 159 is fixedly installed on the outer ring surface of each group of sector-shaped liquid storage cavities 158. The self-sealing rubber spray nozzle 159 is an overall structure of four closely-fitting sector-shaped sealing sheets. A bent outer rod 156 that is hermetically inserted into the sector-shaped liquid storage cavity 158 is fixedly connected to the bottom surface of the threaded sleeve disk 154 at a position corresponding to each group of sector-shaped liquid storage cavities 158. A piston plate 157 is fixedly installed on each bent outer rod 156 extending into the sector-shaped liquid storage cavity 158.

[0058] Among them, the configured sealing disc 151 is for sealing the bottom extending end of the third shaft rod 79. The limiting sleeve housing 153 arranged at the bottom of the multi-ring chassis 8 is for cooperating with the bump 155 to limit the threaded sleeve disc 154 in this direction. During the rotation of the bidirectional threaded rod 152, the engaged threaded sleeve disc 154 can only move up and down reciprocally along the limiting sleeve housing 153. The so-called self-sealing rubber nozzle 159 is actually a structure of four closely-fitting fan-shaped sealing pieces in the prior art. Without the action of pressure, the four closely-fitting fan-shaped sealing pieces are in a sealed and tight state due to the toughness of their own materials. Under the state of being pressured, they will all be pushed open by the pressure, that is, the sealed state is opened.

[0059] As Figures 1 to 10 shown, the auxiliary reagent self-supplying mechanism 15 further includes four liquid supplement conduits 1510 hermetically inserted from the bottom of the funnel bottom bin 12, and each inserted liquid supplement conduit 1510 is connected to the fan-shaped liquid storage cavity 158 on the same side. The bottom of the bidirectional threaded rod 152 is also fixedly connected with a fourth shaft rod 1511, and a fourth leakage port 13 for the fourth shaft rod 1511 to hermetically pass through is also opened at the center position of the bottom of the funnel bottom bin 12, and the fourth shaft rod 1511 passing through the fourth leakage port 13 is fixedly connected with the first shaft rod 610.

[0060] As Figures 1 to 10 shown, the auxiliary reagent self-supplying mechanism 15 further includes four groups of auxiliary reagent storage boxes 17 fixedly installed on the outer surface of the liquid storage cylinder 71. A second drain hose 18 is fixedly connected to the bottom of each group of auxiliary reagent storage boxes 17, and one end of the liquid supplement conduit 1510 hermetically inserted from the bottom of the funnel bottom bin 12, which is far away from the fan-shaped liquid storage cavity 158, is fixedly connected with the second drain hose 18 on the same side.

[0061] Among them, the four configured auxiliary reagent storage boxes 17 are used to store four different types of auxiliary reagents. The so-called auxiliary reagents are reagents that assist the lubricating reagent in mixing. In the prior art, in order to reduce the friction between the roller and the fiber and at the same time not cause pollution to the fiber or affect its quality, the lubricating reagent used will choose silicone oil or other synthetic oils as lubricants to significantly reduce the friction coefficient. That is to say, the liquid storage cylinder 71 stores silicone oil or other synthetic oils. And because friction easily generates static electricity, it is very necessary to add an antistatic component to the lubricating oil. Therefore, an antistatic agent can be stored in one of the four auxiliary reagent storage boxes 17 to help neutralize the static charges generated by friction and prevent the fibers from adsorbing onto the roller to form flyers. A non-ionic surfactant can also be stored to improve the conductivity of the roller surface and accelerate the dissipation of static charges. Further, considering that the surface temperature of the roller is relatively high during the high-speed operation of the spinning frame, the lubricating oil must have good heat resistance to avoid decomposition or failure due to overheating. Therefore, a heat-resistant surfactant can also be stored in one of the storage boxes to improve the heat resistance. And in view of the strict requirements of the textile industry for product safety, the selected lubricating oil also needs to meet relevant environmental protection standards to ensure that it is harmless to human health and does not pollute the final product. Therefore, a natural characteristic biodegradable reagent can also be stored in one of the storage boxes to better ensure the environmental protection performance of the lubricating grease.

[0062] As Figures 1 to 10 shown, fifth drain openings 14 are also formed at both bottom side end positions of the hopper bottom bin 12 for communicating and connecting with a first drain hose 16 passing through the upper surface of the disc sleeve 61. An open stirrer 73 is fixedly connected to the outer surface of the second shaft rod 72. A fiber filament winding module 3 is fixedly installed on the outside of the assembly base frame 1.

[0063] Among them, the configured fifth drain openings 14 are used to introduce the mixed reagent from the hopper bottom bin 12 into the first drain hose 16 and then into the cavity of the socket bracket 62. The open stirrer 73 configured on the outer surface of the second shaft rod 72 is used to stir the lubricating reagent inside the liquid storage cylinder 71 by the rotation of the second shaft rod 72, improve the fluidity of the reagent to be mixed, and provide better mixing activity for subsequent mixing. The configured fiber filament winding module 3 is a sleeve shaft structure for inserting fiber filaments in the prior art.

[0064] The specific working principle provided by the present invention is as follows:

[0065] When the present invention is in use, first, a lubricating reagent and auxiliary reagents are respectively filled in the liquid storage cylinder 71 and the four groups of auxiliary reagent storage boxes 17 on the outer surface. Then, the fiber filaments to be processed are wound on the fiber filament winding module 3, and the fiber filaments are passed through the flared opening and clamped between the roller sleeves of the first driving roller sleeve 2 and the second driving roller sleeve 5. The rotational speeds of the front and rear driving rollers are changed according to the requirements of filament splitting to form a rotational speed difference for automatic filament splitting.

[0066] Then, during the working process, the second shaft rod 72 at the output end of the servo motor 19 can be driven to rotate, so that the circular sleeve cavity 74 at the bottom of the second shaft rod 72 drives the circular ring cavity 75 to rotate in the gaps of the multi-ring chassis 8. The circular ring cavity 75 is heated by using the first friction coating 78 and the second friction coating 9 on the contact surface in cooperation with the heat-conducting material. The reagent that enters the cavity through the first leak port 76 opened on the upper surface of the circular ring cavity 75 will discharge a part of the reagent into the funnel bottom bin 12 when the second leak port 77 of each side of the circular ring cavity 75 aligns with the third leak port 10 during the rotation of the circular ring cavity 75. Therefore, during the working process, the heated lubricating reagent will be stored in the funnel bottom bin 12.

[0067] Furthermore, since the third shaft rod 79 is integrated with the circular ring cavity 75, it will also rotate. During the rotation of the third shaft rod 79, the bidirectional threaded rod 152 at the bottom can be controlled to drive the threaded sleeve plate 154 engaged on the outer surface to reciprocate up and down along the limit sleeve housing 153, so as to control the outer bending rods 156 on the four sides of the threaded sleeve plate 154 to drive the piston plate 157 to reciprocally extrude the fan-shaped liquid storage cavity 158. During the reciprocal extrusion process inside the fan-shaped liquid storage cavity 158, the auxiliary reagent stored in the fan-shaped liquid storage cavity 158 can be discharged to be mixed with the heated lubricating reagent in the cavity to improve the mixing effect. During the process of the piston plate 157 reciprocally extruding in the fan-shaped liquid storage cavity 158, the reagent stored in the auxiliary reagent storage box 17 will also be sucked into the fan-shaped liquid storage cavity 158 during the pulling process to complete the work of automatically replenishing the reagent.

[0068] Finally, the mixed reagent can enter the cavity of the sleeve mouth support 62 from the funnel bottom bin 12 through the first liquid discharge hose 16 at the fifth leak port 14, and then be transported to the twisting end faces of the first externally extending twisting rod 64 and the second externally extending twisting rod 65 through the cavity conduits 63 on both sides of the sleeve mouth support 62. Moreover, by using the rotational force of the second shaft rod 72 again, the rotation of the second gear disk 611 is driven, so that the second gear disk 611 controls the synchronous rotation of the first externally extending twisting rod 64 and the second externally extending twisting rod 65 on both sides without external interference to lubricate the twisted silk thread and ensure the stability of the overall driving end.

[0069] The present invention encompasses any alternatives, modifications, equivalent methods, and solutions that are within the spirit and scope of the present invention. To enable the public to have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention. However, those skilled in the art can fully understand the present invention even without the description of these details. Additionally, well-known methods, processes, procedures, components, and circuits are not described in detail to avoid unnecessary confusion with the essence of the present invention.

[0070] The above description is only a preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
