Description

Technical Field

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

[0002] The spinning frame is the core equipment in the spinning process. It uses the drafting mechanism to evenly stretch and twist the coarse fiber strips to finally form fine yarn that meets the requirements. During the drafting process, the speed difference between the front roller and the rear roller determines the drafting multiple, which directly affects the count and quality stability of the yarn. In traditional spinning frames, the adjustment of the drafting multiple usually relies on a fixed combination of gear sets or pulley transmission ratios, which requires stopping the machine to replace gears or adjust the transmission structure, resulting in reduced production efficiency and making it difficult to meet the flexible production needs of multiple varieties and small batches of yarn.

[0003] Although the existing drafting multiple adjustable device has achieved a certain degree of dynamic adjustment through mechanical structure improvement, such as adjustable gear box, it lacks the coordinated optimization of the friction problem between the roller and the fiber strip. Due to the long-term high-speed operation of the roller surface and the lack of continuous lubrication, the fiber strip is prone to static electricity, flying and yarn breakage due to friction during the drafting process, which is more obvious when processing high-count yarn or synthetic fiber.

[0004] Although the prior art can improve the above problems by lubricating the fiber strips through external oiling equipment or manual methods, such methods require additional processes, resulting in increased equipment complexity, extended downtime, and difficulty in ensuring lubrication uniformity, and it is impossible to reduce friction loss while improving regulation efficiency.

[0025] like Figures 1 to 10 As shown, an embodiment of the present invention provides an adjustable draft multiple device for a spinning frame, comprising an assembly base frame 1, a plurality of first driving roller sleeves 2 are arranged on both sides of the surface of the assembly base frame 1, and an outward sleeve frame 4 is also movably hinged on the upper surface of the assembly base frame 1, and second driving roller sleeves 5 are arranged at positions on both sides of the surface of the outward sleeve frame 4 facing the first driving roller sleeves 2, and a lubricant twisting mechanism 6 is also arranged at the position of the second driving roller sleeve 5 located in the middle of the upper surface of the outward sleeve frame 4, so as to inject lubricant into the second driving roller sleeves 5 on both sides of the position to perform spinning lubrication and twisting operations; The upper side of the lubricant twisting mechanism 6 is provided with a lubricant mixing mechanism 7 for replenishing lubricant to the lubricant twisting mechanism 6. The lubricant twisting mechanism 6 comprises a disc sleeve 61 and a first outwardly extending twisting rod 64 and a second outwardly extending twisting rod 65 movably arranged on both sides of the disc sleeve 61, and the first outwardly extending twisting rod 64 and the second outwardly extending twisting rod 65 are respectively aligned with the first driving roller sleeve 2 on the same side; Among them, a servo motor 19 is fixedly installed at the top axial position of the lubricant mixing mechanism 7, and 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, and a second shaft rod 72 fixedly connected to the output end of the servo motor 19 is movably installed inside the liquid storage cylinder 71, and an auxiliary reagent self-replenishing mechanism 15 is also configured at the bottom of the second shaft rod 72, so as to control the auxiliary reagent stored in the auxiliary reagent self-replenishing mechanism 15 to dissolve in the lubricant through the driving action of the output end of the servo motor 19 to perform deep lubrication and twisting operations on the spun yarn.

[0026] In order to solve the problem that the drafting end of the existing spinning machine lacks coordinated optimization of the friction problem between the rollers and the fiber strips, the above-mentioned technical solution is now adopted to solve the problem. The above-mentioned technical solution is mainly composed of an assembly base frame 1, a first driving roller sleeve 2, an outward sleeve frame 4, a second driving roller sleeve 5, a lubricant twisting mechanism 6 and a lubricant mixing mechanism 7. The assembly base frame 1 is a driving base device of the spinning machine in the prior art, and is the basic supporting part of the entire spinning machine. It not only bears the weight of all mechanical components, but also ensures the stability of the machine during operation. The output end is arranged inside the shell to drive the first driving roller sleeve 2 on the output shafts on both sides, and the first driving roller sleeve 2 and the second driving roller sleeve 5 are both roller rod structures in the prior art. The system is responsible for drafting the coarse yarn and is made of sturdy and durable metal material with sufficient strength. The strength and rigidity are used to resist the vibration caused by high-speed operation. It is divided into front roller, middle roller and back roller. The front roller outputs the whiskers after the final drafting and sends them to the twisting zone, while the middle roller participates in the drafting process in the middle stage to help adjust the fiber arrangement and cooperates with the feeding mechanism to control the speed of the roving entering the drafting zone. The so-called feeding mechanism is a trumpet-shaped structure for fiber entry, which belongs to the double-inlet and single-outlet trumpet in the prior art. The overall structure has a 32.5mm large diameter technical improvement of the front stop of the roving machine and a 34mm large diameter structure of the front stop of the roving machine. The configured outward-turning sleeve frame 4 also belongs to the inherent structure hinged on the assembly base frame 1 in the prior art, which 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; The configured lubricant twisting mechanism 6 is a structure installed on the outer-turned sleeve frame 4 as a whole. The roller rod structure extending from the output ends on both sides of the lubricant twisting mechanism 6 replaces the middle roller structure located in the middle position in the prior art so as not to interfere with the working characteristics of the front roller and the rear roller. The so-called lubricant mixing mechanism 7 is a mechanism configured on the upper side of the lubricant twisting mechanism 6 to replenish the lubricant to the lubricant twisting mechanism 6. Specifically, the lubricant twisting mechanism 6 includes a disc sleeve 61 and a first outwardly extending twisting rotating rod 64 and a second outwardly extending twisting rotating rod 65 which are movably arranged on both sides of the disc sleeve 61, that is, it is used to replace the middle roller structure located in the middle position in the prior art, wherein the lubricant mixing mechanism 7 is fixed at the top axial position A servo motor 19 is installed. The so-called servo motor 19 is a driving motor structure capable of servo control in the prior art, which is used to provide the device with driving force. A second shaft rod 72 is arranged inside the liquid storage cylinder 71, and an auxiliary reagent self-replenishing mechanism 15 is also arranged at the bottom of the second shaft rod 72. During operation, the auxiliary reagent stored in the auxiliary reagent self-replenishing 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 agent mixed with the auxiliary reagent is guided to the first outwardly extending twisting rotating rod 64 and the second outwardly extending twisting rotating rod 65 through the conveying action of the lubricant twisting mechanism 6, so as to perform deep lubrication and twisting operations on the spun 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 structure of the prior art.

[0027] like Figures 1 to 10 As shown, a sleeve bracket 62 is fixedly installed at the inner center position of the disc sleeve 61, and the sleeve position of the sleeve bracket 62 is a cavity structure, and a cavity catheter 63 is movably installed through the cavity structure, and the cavity catheter 63 is communicated with the sleeve cavity of the sleeve bracket 62. A first outwardly extending twisting rod 64 and a second outwardly extending twisting rod 65 that can movably pass through the side wall of the disc sleeve 61 are respectively fixedly installed on both sides of the cavity catheter 63. A twisting sleeve 66 is fixedly installed on the protruding ends of the first and second protruding twisting rods 64 and 65, and the outer surfaces of the twisting sleeves 66 are covered with adsorption coatings, and each twisting sleeve 66 has a liquid conducting lumen channel 68 at the inner axial position for supplying liquid to the adsorption coating, and the first and second protruding twisting rods 64 and 65 have miniature openings 67 inside that communicate with the liquid conducting lumen channel 68 and the cavity catheter 63 on the same side.

[0028] Among them, the configured sleeve bracket 62 is as shown in the attached specification. Fig.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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] The circular sleeve cavity 74 and the annular cavity 75 disposed at the bottom of the second shaft 72 are an integral structure, and the annular cavity 75 is composed of a plurality of groups of multi-annular cavities coaxial with the circular sleeve cavity 74, and there is a gap between each group of annular cavities 75, and the gap is for fitting with the multi-annular chassis 8, so that the first friction coating 78 on the outer annular surface of each group of annular cavities 75 fits with the second friction coating 9 on the annular surface of the multi-annular chassis 8. During the high-speed rotation of the annular cavity 75, the two fitted first friction coatings 78 and the second friction coatings 9 can generate heat by friction, and because each group of annular cavities Several groups of first leaks 76 are provided on the upper surface of the annular cavity 75, and only four groups of second leaks 77 spaced 90 degrees apart are provided on the lower surface of each group of annular cavities 75. Specifically, the openings on the upper side of each group of annular cavities 75 are much larger than the openings on the lower side, so that the reagents stored on the upper side of the liquid storage cylinder 71 can smoothly enter the annular cavity 75 from the first leaks 76 on the upper side of each group of annular cavities 75, but are difficult to be discharged from the bottom of the annular cavity 75. By utilizing the flow rate difference, the entering reagents can be stored in each group of annular cavities 75 for a period of time, so that the reagents can be heated in the cavity for a longer time.

[0033] like Figures 1 to 10 As shown, the bottom of the liquid storage cylinder 71 is fixedly connected to a multi-ring chassis 8, and the multi-ring chassis 8 is a concave disk structure composed of multiple groups of concentric circular rings as a whole, and the multi-ring chassis 8 is one-to-one embedded with the circular ring cavity 75 at the bottom of the circular sleeve cavity 74, and the circular surface of the multi-ring chassis 8 is also fixedly installed with a second friction coating 9 corresponding to the first friction coating 78 on the outer surface of the circular ring cavity 75, and the bottom of the multi-ring chassis 8 is fixedly connected to a funnel bottom bin 12, and the bottom surface of each group of circular ring grids of the multi-ring chassis 8 is provided with four groups of third leakage openings 10, and each third leakage opening 10 is 90 degrees apart, and a central conduit 11 for allowing the third shaft rod 79 to penetrate into the funnel bottom bin 12 is also fixedly installed at the center position of the multi-ring chassis 8.

[0034] Among them, the configured multi-circular ring chassis 8 is a concave disk structure composed of multiple groups of concentric circular rings. The concave disk structure is set on the one hand to fit the circular ring cavity 75, and on the other hand to make the upper surface of the fitted circular ring 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. Furthermore, the bottom surface of each group of circular ring grids of the multi-circular ring chassis 8 is provided with four groups of third leakage holes 10, and each third leakage hole 10 is 90 degrees apart. The circular ring cavity 75 is set on the upper surface of the multi-circular ring chassis 8. Only when the second leakage hole 77 opened at the bottom of the circular ring cavity 75 is aligned with the third leakage hole 10, the reagent stored in each group of cavities of the circular ring cavity 75 will be discharged, which further increases the residence time of the reagent in the circular ring cavity 75 and provides a longer heating environment for it.

[0035] like Figures 1 to 10 As shown, the auxiliary reagent self-replenishing mechanism 15 includes a sealing disk 151 fixedly installed at the bottom of the third shaft rod 79 that penetrates into the funnel bottom bin 12, and the sealing disk 151 is tightly attached to the bottom of the multi-ring chassis 8 as a whole. A bidirectional threaded rod 152 is fixedly connected at the bottom center position of the sealing disk 151, and a threaded sleeve 154 is meshingly installed on the bidirectional threaded rod 152. The bottom of the multi-ring chassis 8 is also fixedly connected to a limiting sleeve 153, and the side of the threaded sleeve 154 is fixedly connected to a protrusion 155 embedded in the limiting sleeve 153.

[0036] like Figures 1 to 10 As shown, the auxiliary reagent self-replenishing mechanism 15 also includes four groups of fan-shaped liquid storage cavities 158 fixedly installed at the center position of the bottom circle of the funnel bottom bin 12, and a self-sealing rubber nozzle 159 is fixedly installed on the outer annular surface of each group of fan-shaped liquid storage cavities 158. The self-sealing rubber nozzle 159 is a structure of four tightly fitting fan-shaped sealing sheets as a whole. The bottom surface of the threaded sleeve 154 is fixedly connected with an outer bending rod 156 that is sealingly inserted into the inside of the fan-shaped liquid storage cavity 158 at a position facing each group of fan-shaped liquid storage cavities 158, and a piston plate 157 is fixedly installed on each outer bending rod 156 that extends into the fan-shaped liquid storage cavity 158.

[0037] Among them, the configured sealing disk 151 is used to seal the protruding end at the bottom of the third shaft rod 79, and the limiting sleeve 153 arranged at the bottom of the multi-ring chassis 8 is used to cooperate with the protrusion 155 to limit the threaded sleeve 154 in this direction. During the rotation of the bidirectional threaded rod 152, the engaged threaded sleeve 154 can only move up and down along the limiting sleeve 153. The so-called self-sealing rubber nozzle 159 is actually a structure of four tightly fitted fan-shaped sealing sheets in the prior art. When there is no pressure, the four tightly fitted fan-shaped sealing sheets are in a sealed and tight state due to the toughness of their own materials. When under pressure, they will be squeezed open by the pressure, that is, the sealed state is opened.

[0038] like Figures 1 to 10 As shown, the auxiliary reagent self-replenishing mechanism 15 also includes four fluid infusion tubes 1510 that are sealably inserted from the bottom of the funnel bottom bin 12, and each inserted fluid infusion tube 1510 is connected to the fan-shaped liquid storage cavity 158 on the same side, and the bottom of the bidirectional threaded rod 152 is also fixedly connected to a fourth shaft rod 1511, and a fourth leakage port 13 is also opened at the bottom center position of the funnel bottom bin 12 for the fourth shaft rod 1511 to seal through, and the fourth shaft rod 1511 passing through the fourth leakage port 13 is fixedly connected to the first shaft rod 610.

[0039] like Figures 1 to 10 As shown, the auxiliary reagent self-replenishing mechanism 15 also includes four groups of auxiliary reagent storage boxes 17 fixedly mounted on the outer surface of the liquid storage cylinder 71, and each group of auxiliary reagent storage boxes 17 is fixedly connected to the bottom of a second drainage hose 18, and the end of the liquid replenishment catheter 1510 sealed and inserted from the bottom of the funnel bottom bin 12 away from the fan-shaped liquid storage cavity 158 is fixedly connected to the second drainage hose 18 on the same side.

[0040] Among them, the four sets of auxiliary reagent storage boxes 17 are configured to store four sets of different types of auxiliary reagents, and the so-called auxiliary reagents are reagents used to assist in mixing in the lubricating reagent. In the prior art, in order to reduce the friction between the roller and the fiber without causing pollution to the fiber or affecting its quality, the lubricating reagent used will select silicone oil or other synthetic oil as a lubricant to significantly reduce the friction coefficient. That is to say, silicone oil or other synthetic oil is stored in the liquid storage cylinder 71. Since friction easily generates static electricity, it is very necessary to add antistatic components to the lubricating oil. Therefore, an antistatic agent can be stored in one of the four sets of auxiliary reagent storage boxes 17. The antistatic agent helps neutralize the static charge generated by friction. , to prevent fibers from being adsorbed onto the rollers to form flying flowers, and to store non-ionic surfactants, which can improve the conductivity of the roller surface and accelerate the dissipation of static charge. Furthermore, considering that the roller surface temperature is high when the spinning frame is running at high speed, the lubricating oil must have good heat resistance to avoid decomposition or failure due to overheating. Therefore, a heat-resistant active agent can be stored in one of the storage boxes to improve the heat resistance. In view of the strict requirements of the textile industry on product safety, the selected lubricating oil must also meet the relevant environmental protection standards to ensure that it is harmless to human health and does not pollute the final product. Therefore, a natural biodegradable agent can also be stored in a group of storage boxes to better ensure the environmental performance of the lubricating grease.

[0041] like Figures 1 to 10 As shown, a fifth leakage port 14 is provided at both side ends of the bottom of the funnel bottom bin 12 for connecting to the first liquid discharge hose 16 passing through the upper surface of the disc sleeve 61, an open stirring frame 73 is fixedly connected to the outer surface of the second shaft 72, and a fiber winding module 3 is fixedly installed on the outer side of the assembly base frame 1.

[0042] Among them, the fifth leakage port 14 is configured to introduce the mixed reagent from the funnel bottom bin 12 into the first drainage hose 16, and then from the first drainage hose 16 into the cavity of the sleeve bracket 62, and the open stirring frame 73 configured on the outer surface of the second shaft 72 is to stir the lubricating reagent inside the liquid storage cylinder 71 by the rotation of the second shaft 72, so as to improve the fluidity of the reagent to be mixed and provide better mixing activity for subsequent mixing, and the configured fiber winding module 3 is a sleeve shaft structure used for inserting fiber filaments in the prior art.

[0043] The specific working principle provided by the present invention is as follows: When the present invention is used, firstly, the lubricating agent and the auxiliary agent are respectively filled in the liquid storage cylinder 71 and the four groups of auxiliary agent storage boxes 17 on the outer surface, and then the fiber to be processed is wound on the fiber winding module 3, and the fiber passes through the bell mouth and is clamped between the roller sleeves of the first driving roller sleeve 2 and the second driving roller sleeve 5. The rotation speed of the front and rear driving rollers is changed according to the requirements of the wire separation to form a speed difference, and the automatic wire separation is performed; Then, during the working process, the second shaft 72 at the output end can be driven to rotate by the servo motor 19, so that the circular sleeve cavity 74 at the bottom of the second shaft 72 drives the annular cavity 75 to rotate in the gap of the multi-annular chassis 8, and the first friction coating 78 and the second friction coating 9 on the contact surface are used in combination with the heat-conducting material to heat the annular cavity 75, and the reagent entering the cavity through the first leakage port 76 opened on the upper surface of the annular cavity 75, when the annular cavity 75 on each side rotates and the second leakage port 77 is aligned with the third leakage port 10, a part of the reagent will be discharged into the funnel bottom bin 12, so during the working process, the heated lubricating reagent will be stored in the funnel bottom bin 12; Then, since the third shaft 79 is integrated with the annular cavity 75, it will also rotate. During the rotation of the third shaft 79, the bidirectional threaded rod 152 at the bottom can be controlled to drive the threaded sleeve 154 meshing on the outer surface to rotate back and forth along the limiting sleeve 153, so as to control the outer bending rods 156 on the four sides of the threaded sleeve 154 to drive the piston plate 157 to reciprocate and squeeze the fan-shaped liquid storage cavity 158. During the reciprocating squeezing 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 mix with the heated lubricating reagent in the cavity to improve the mixing effect. During the reciprocating squeezing process in the fan-shaped liquid storage cavity 158, the piston plate 157 will also suck the reagent stored in the auxiliary reagent storage box 17 into the fan-shaped liquid storage cavity 158 during the pulling process, thereby completing the work of automatically replenishing the reagent. Finally, the mixed reagent can enter the cavity of the sleeve bracket 62 from the funnel bottom bin 12 through the first drainage hose 16 at the fifth leakage port 14, and then be transported to the twisting end surfaces of the first and second extended twisting rods 64 and 65 through the cavity ducts 63 on both sides of the sleeve bracket 62, and the rotational force of the second shaft 72 is used again to drive the rotation of the second gear plate 611, so that the second gear plate 611 controls the first and second extended twisting rods 64 and 65 on both sides to rotate synchronously without external interference, thereby lubricating the twisted silk thread and ensuring the stability of the overall driving end.

In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details.
