Description

Technical Field

[0001] This invention relates to the field of filament splitting roller technology, and more specifically to a maintenance device for filament splitting rollers in texturing machines. Background Technology

[0002] The primary function of the fiber separating roller in a texturing machine is to guide and separate fiber filaments, ensuring their uniform distribution during processing, thereby improving processing efficiency and product quality. Through its special design and materials, the separating roller effectively handles and distributes fiber filaments, making it a key rotating component in the texturing machine. Its design takes into account the characteristics of the fiber filaments and processing requirements to ensure optimal separation and guidance. Proper lubrication and maintenance of the separating roller are crucial; regular maintenance ensures its optimal performance and prevents product processing abnormalities caused by abnormal roller rotation.

[0003] Currently, the lubrication requirement for the splitting roller is to apply oil lubricant periodically. After lubrication, manually rotate the splitting roller. (See below) Figure 1 As shown, grease is injected through the central hole 2 of the sealing cap at the tail of the splitting roller, making the splitting roller stand upright. Manual rotation allows the grease to enter the internal cage and bearing 1 of the splitting roller for lubrication. The sealing ring 3 prevents grease from flowing out during rotation and potentially splashing. The polyester fibers are stretched on the surface of the splitting roller housing 4. The splitting roller shaft 5 mainly serves for fixing and supporting. However, as the service life of the texturing machine's splitting roller increases, the lubrication cycle gradually shortens, manual rotation becomes less effective, and grease lubrication is incomplete, leading to a gradual increase in the number of abnormal splitting rollers and affecting daily production.

[0004] It should be noted that the information disclosed in the background section above is only for understanding the background of this application. Therefore, the background section of this invention may include background information about the problems or environment of this invention, and is not necessarily a description of the prior art. Thus, the content included in the background section does not constitute an admission of the prior art by the applicant. Summary of the Invention

[0005] The purpose of this invention is to overcome one or more shortcomings in the prior art and to provide an improved maintenance device for the splitting roller of a texturing machine.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A maintenance device for a texturing machine splitting roller, the maintenance device comprising: At least one set of clamping assemblies, each set of clamping assemblies including multiple clamping members, the multiple clamping members being configured into a clamping member array; the clamping members are rotatably disposed and are provided with a filament splitting roller shaft clamping part and a rotatable mating part; The system includes a drive assembly corresponding to the number of clamping components and a limiting assembly corresponding to the number of clamping members. The limiting assembly is located above the clamping members and includes a limiting member that can be opened and closed. The drive assembly includes a drive member that is rotatably disposed and a transmission belt that is pultrusively connected to the drive member. The transmission belt is wound around the rotating engagement portion of the clamping member and is used to drive the clamping member to rotate; the clamping member array includes multiple rows of clamping members arranged side by side along a first path and multiple columns of clamping members arranged side by side along a second path. In the same row on the first path, any two adjacent clamping members rotate in opposite directions; in the same column on the second path, all clamping members rotate in the same direction.

[0007] In some embodiments of the present invention, the clamping array includes a first clamping member and a second clamping member; one of the first clamping member and the second clamping member is the first clamping member to be contacted when the transmission belt enters the clamping array, and the other of the first clamping member and the second clamping member is the last clamping member to be contacted when the transmission belt moves away from the clamping array; When the number of clamping members in the same row on the first path is an even number, the mating part of the transmission belt that contacts the rotating mating part of the first clamping member and the mating part of the transmission belt that contacts the rotating mating part of the second clamping member are both located between the first clamping member and the second clamping member. When the number of clamping members in the same row on the first path is odd, both the first clamping member and the second clamping member are located between the mating parts of the transmission belt that contact the rotating mating part of the first clamping member and the mating parts of the transmission belt that contact the rotating mating part of the second clamping member.

[0008] In some embodiments of the present invention, the limiting member forms a limiting cavity, the limiting cavity including a first state and a second state. When the limiting cavity is in the first state, the limiting cavity has a first radial dimension in the horizontal direction. When the limiting cavity is in the second state, the limiting cavity has a second radial dimension in the horizontal direction. The first radial dimension is smaller than the second radial dimension.

[0009] In some embodiments of the present invention, the limiting member includes a first limiting sub-part and a second limiting sub-part respectively movably disposed thereon, the first limiting sub-part and the second limiting sub-part surrounding to form the limiting cavity; Furthermore, the limiting assembly also includes a first rod, a second rod arranged parallel to the first rod, and a fastener. The two ends of the first limiting sub-part are respectively sleeved on the first rod, and the two ends of the second limiting sub-part are respectively sleeved on the second rod. The fastener includes a fastening sub-part capable of driving the first limiting sub-part and the second limiting sub-part to move respectively.

[0010] In some embodiments of the present invention, the clamping member includes a clamping body rotatably disposed thereon and the filament splitting roller clamping part and the rotatable mating part respectively disposed on the clamping body; the filament splitting roller clamping part includes a clamping cavity and an elastic member formed around the clamping cavity and capable of freely entering and exiting the clamping cavity, wherein the extension and retraction direction of the elastic member intersects with the height direction of the clamping cavity.

[0011] In some embodiments of the present invention, the extension and retraction direction of the elastic element is perpendicular to the height direction of the clamping cavity.

[0012] In some embodiments of the present invention, the elastic element has multiple members and is uniformly distributed around the clamping cavity.

[0013] In some embodiments of the present invention, the splitting roller shaft clamping part further includes abutting members that correspond one-to-one with the number of the elastic members, one end of the elastic member being fixedly disposed and the other end being connected to the corresponding abutting member.

[0014] In some embodiments of the present invention, the rotating engagement portion includes a recess formed on the clamping body, and the transmission belt engages with the recess to achieve transmission.

[0015] In some embodiments of the present invention, the splitting roller shaft clamping part is located at the end of the clamping body, and the rotating mating part is located in the middle of the clamping body.

[0016] In some embodiments of the present invention, the limiting component is located directly above the clamping member.

[0017] In some embodiments of the present invention, the extension line of the first path intersects the extension line of the second path. Further, the extension lines of the first path and the second path are perpendicular to each other.

[0018] In some embodiments of the invention, the number of clamps in the same column on the second path is an even number.

[0019] In some embodiments of the present invention, the maintenance device further includes a platform and a base, the platform being disposed on the base with a gap between them; the clamping assembly and the driving assembly are respectively disposed on the base, the limiting assembly is disposed on the platform, and the clamping member extends in the vertical direction and has at least a portion located in the gap.

[0020] Due to the application of the above-mentioned technical solution, the present invention has the following advantages compared with the prior art: Currently, each shaft of the splitting roller has an independent grease chamber, and grease is added during later maintenance, which easily leads to uneven initial distribution. The current method is to manually rotate each one one by one, but problems such as incomplete grease dispersion and poor lubrication still exist. The inventors of this invention innovatively propose to use the same transmission belt to drive all clamping components (the splitting shaft is set on the clamping components and moves synchronously), and to make any two adjacent clamping components in the same row on the first path rotate in opposite directions; in the same column on the second path, all clamping components rotate in the same direction. This ensures that each shaft starts and stops synchronously, rotates at the same speed, and has the same forward and reverse rotation process, so that the grease in each independent chamber undergoes consistent shear-time conditions, thereby improving batch uniformity. Furthermore, by realizing the forward / reverse rotation of adjacent shafts, a forward and reverse grease uniformity cycle can be adopted in the process, breaking the axial aggregation and dead zone retention caused by unidirectional shearing in the vertical chamber, and promoting the full spreading and wetting of the subsequently added grease. Although the grease paths between multiple shafts are not interconnected, a smooth start-stop impact can be achieved through weak coupling via belts. For example, if the initial grease dispersion of one or more split shafts is uneven, or even biased to one side, the start and stop of each split shaft can be mutually restrained by the same transmission belt, making the start and stop of all split shafts tend to be balanced and smooth. By controlling sufficient rotation time, the severe unidirectional shearing effect caused by the independent start of a single split shaft can be greatly reduced, which causes the grease to be thrown to a local area. This is beneficial for the stable dispersion of high-viscosity grease and also helps to achieve batch-to-batch uniformity. Attached Figure Description

[0022] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0024] The following is combined with Figures 1 to 10 The technical solution of the present invention will be further described below.

[0025] See Figure 1As shown, it provides an exemplary schematic diagram of the current filament splitting roller. After grease is injected into the filament splitting shaft through the middle hole 2 of the tail sealing cover, the filament splitting shaft is usually held vertically with the middle hole 2 of the tail sealing cover facing upwards. The grease is injected through a needle hole, making it difficult for it to come out again. After injecting the grease, the filament splitting roller shaft 5 is usually manually rotated by holding the filament splitting shaft housing 4, dispersing the grease during the rotation. However, in practice, it has been found that for the currently produced varieties (15D-35D) fine denier filament products, even after lubrication is performed before production to address the rotation issue of the filament splitting roller, batches of filament splitting rollers still fail to rotate, resulting in abnormalities and poor production, failing to achieve the desired effect. The high viscosity of the grease after lubrication leads to uneven lubrication, resulting in high rotational resistance of the bearings inside the filament splitting roller, and the thin filaments with low tension, indicating insufficient rotational flexibility of the filament splitting roller. This suggests that the current manual rotation lubrication effect is poor and the grease lubrication is incomplete.

[0026] Based on the aforementioned problems, this invention innovatively provides a rotational lubrication dispersion method that departs from the one-to-one method. It employs a single drive corresponding to multiple threaded shafts, specifically, each threaded shaft has its own independent rotation direction in different directions. Furthermore, the rotation directions of adjacent clamping members, particularly those along the first path, are opposite. This arrangement causes the originally independently dispersed lubrication to interact with each other. Uneven distribution of lubricating oil in any threaded shaft, which affects the transmission belt, will be distributed to the other threaded shafts. Thus, although the threaded shafts rotate independently, they also influence each other, achieving a weak coupling effect. This greatly avoids the severe interference of start-stop on the grease during one-to-one rotation, making start-stop smoother. Simultaneously, with the same transmission, it is easier to control the rotation time, resulting in a more uniform lubrication effect for each threaded shaft.

[0027] See Figures 2 to 10As shown, this example provides a maintenance device for a texturing machine's splitting roller. The device includes at least one set of clamping components 1, a drive component, and a limiting component 3. Each clamping component 1 includes multiple clamping members 11, which are configured as a clamping member array 12. The number of clamping components 1 corresponds one-to-one with the number of drive components, and the number of limiting components 3 corresponds one-to-one with the number of clamping members 11. The clamping members 11 are rotatably arranged and are provided with a splitting roller shaft clamping portion 111 and a rotating mating portion 112. The limiting components 3 are located above the clamping members 11. The system includes an opening and closing limiting member 31, and a driving assembly including a rotatably disposed driving member 21 and a transmission belt 22 connected to the driving member 21. The transmission belt 22 is wound around the rotating mating part 112 of the clamping member 11 and is used to drive the clamping member 11 to rotate. The clamping member array 12 includes multiple rows of clamping members arranged side by side along a first path X and multiple columns of clamping members arranged side by side along a second path Y. In the same row on the first path X, any two adjacent clamping members 11 rotate in opposite directions. In the same column on the second path Y, all clamping members 11 rotate in the same direction. In this example, the limiting assembly 3 is used to limit and fix the housing of the texturing machine's splitting roller, the clamping assembly 1 is used to fix the shaft of the texturing machine's splitting roller, and the driving assembly drives the clamping member 11 to rotate, thereby driving the shaft of the splitting roller to rotate.

[0028] In this example, the clamping array 12 includes a first clamping member 121 and a second clamping member 122. One of the first clamping member 121 and the second clamping member 122 is the first clamping member to contact when the transmission belt 22 enters the clamping array 12, and the other of the first clamping member 121 and the second clamping member 122 is the last clamping member to contact when the transmission belt 22 moves away from the clamping array 12. When the number of clamping members 11 in the same row on the first path X is even, the transmission belt 22 contacts the first clamping member 121. The mating parts of the first clamping member 121 and the second clamping member 122 that are in contact with the rotating mating parts of the transmission belt 22 are both located between the first clamping member 121 and the second clamping member 122. When the number of clamping members 11 in the same row on the first path X is an odd number, the first clamping member 121 and the second clamping member 122 are both located between the mating parts of the transmission belt 22 that are in contact with the rotating mating parts of the first clamping member 121 and the mating parts of the transmission belt 22 that are in contact with the rotating mating parts of the second clamping member 122.

[0029] The limiting component 3 is located directly above the clamping member 11, and the extension line of the first path X intersects the extension line of the second path Y. In this example, the extension lines of the first path X and the second path Y are perpendicular to each other. The number of clamping members 11 in the same column on the second path Y is even.

[0030] The limiting member 31 forms a limiting cavity 311, which includes a first state and a second state. When the limiting cavity 311 is in the first state, it has a first radial dimension in the horizontal direction. When the limiting cavity 311 is in the second state, it has a second radial dimension in the horizontal direction. The first radial dimension is smaller than the second radial dimension. Furthermore, in this example, the limiting member 31 includes a first limiting sub-part 312 and a second limiting sub-part 313 that are movably disposed, as well as a first rod 32, a second rod 33 disposed parallel to the first rod 32, and a fastener (not shown). The first limiting sub-part 312 and the second limiting sub-part 313 enclose each other to form a limiting cavity 311. The two ends of the first limiting sub-part 312 are respectively sleeved on the first rod 32, and the two ends of the second limiting sub-part 313 are respectively sleeved on the second rod 33. The fastener includes a fastening sub-part that can drive the first limiting sub-part and the second limiting sub-part to move respectively, such as a bolt.

[0031] See Figure 9 and Figure 10 As shown, the clamping member 11 includes a clamping body 13 rotatably disposed and a splitting roller shaft clamping portion 111 and a rotating mating portion 112 respectively disposed on the clamping body 13. The splitting roller shaft clamping portion 111 includes a clamping cavity 1111 and an elastic member 1112 formed around the clamping cavity 1111 and capable of freely entering and exiting the clamping cavity 1111. The extension and retraction direction of the elastic member 1112 intersects the height direction of the clamping cavity 1111. The limiting cavity of the limiting member is connected to the clamping cavity and is disposed opposite to it. In this example, the extension and retraction direction of the elastic member 1112 is perpendicular to the height direction of the clamping cavity 1111. There are multiple elastic members 1112, which are evenly distributed around the clamping cavity 1111. The splitting roller shaft clamping portion 111 also includes abutment members 1113 corresponding one-to-one with the number of elastic members 1112. One end of the elastic member 1112 is fixedly disposed, and the other end is connected to the corresponding abutment member 1113. In this example, the abutment 1113 may include, but is not limited to, a spherical shape, etc. Under the action of the elastic member 1112, it only abuts against the shaft of the inserted splitting roller. When it is preferably arranged in multiple directions, it can better hold the shaft of the splitting roller. When the clamping member is driven to rotate, the shaft of the splitting roller will also be driven to rotate synchronously. The housing of the splitting roller is limited and fixed under the action of the limiting component and will not rotate, thereby realizing the rotation and dispersion of the internal grease and making it fully lubricated inside.

[0032] In this example, the elastic element 1112 can be a spring, etc.

[0033] The rotating engagement part 112 includes a recess 1121 formed on the clamping body 13. The transmission belt 22 engages with the recess 1121 to achieve transmission, and the transmission belt 22 can be locked inside the recess 1121. In this example, the splitting roller shaft clamping part 111 is located at the end of the clamping body 13, which is conducive to the vertical placement of the clamping member 11. The rotating engagement part 112 is located in the middle of the clamping body 13, which is conducive to better driving the clamping member 11 to rotate.

[0034] The maintenance device also includes a stage 4 and a base 5. The stage 4 is disposed on the base 5 and there is a gap between the two. The clamping component 1 and the driving component are respectively disposed on the base 5. The limiting component 3 is disposed on the stage 4. The clamping member 11 extends in the vertical direction and has at least a portion located in the gap.

[0035] See Figures 2 to 8As shown, the maintenance device is supported on a base surface (such as the ground) by support feet on the base 5. A platform is provided on the base 5, and the platform 4 is detachably mounted on the platform. There is a space between the platform 4 and the platform that can accommodate components such as clamping parts and transmission belts. The driving part 21 can be a driving wheel or the like, which can rotate under the drive of a motor. At the same time, it drives the transmission belt 22 (such as a transmission belt) wrapped around the driving part to drive the transmission. The transmission belt 22 is wrapped around the clamping part 11, which can drive the clamping part 11 to rotate synchronously. In this example, the number of limiting components 3 and clamping components 11 are the same, corresponding one-to-one and arranged vertically. The splitting spool is inserted from the limiting component 31 of the limiting component 3 into the splitting roller clamping part 111 of the clamping component 11. When driven, the splitting spool is vertically oriented and aligned with or even collinear with the axis of the clamping component 11. The housing of the splitting spool can be limited and fixed by the limiting components. The first limiting sub-part 312 and the second limiting sub-part 313 of the limiting component 31 are respectively clamped on the outer wall of the housing of the splitting spool. They can be made of relatively hard rubber material with a certain degree of elasticity. Optionally, the radial dimension of the limiting cavity enclosed by the first limiting sub-part and the second limiting sub-part can be smaller than the outer diameter of the housing of the splitting spool. The elasticity allows the radial dimension of the limiting cavity to be squeezed and enlarged after the splitting spool is inserted, through elastic deformation, so that the splitting spool can pass through, and the elastic recovery... The function is to firmly squeeze and fix the wire splitting shaft. Of course, other methods can also be used to further ensure that the housing of the wire splitting shaft is fixed. For example, the limiting component 3 also includes a fixed seat 35 with a hollow structure. The first limiting sub-part 312 and the second limiting sub-part 313 are both located in the hollow structure of the fixed seat 35. The first rod 32 and the second rod 33 are both set on the fixed seat 35. Fixing the fixed seat 35 on the platform 4 can achieve the overall fixation of the limiting component. Through the bolt holes 34 provided on the fixed seat, fasteners such as bolts pass through and press against the first limiting sub-part or the second limiting sub-part, so that their positions or states are maintained. It can even drive the first limiting sub-part or the second limiting sub-part to move, thereby further limiting and tightening the housing of the wire splitting shaft. When bolt holes are provided on both sides, the first limiting sub-part and the second limiting sub-part can be pressed or driven to move.

[0036] See Figure 6As shown, when the driving member 21 rotates, the transmission belt 22 is driven to rotate. The transmission belt 22 is interlaced and wound around the clamping members 11 in the clamping member array 12, forming a serpentine winding. This results in adjacent clamping members 11 along the X path rotating in opposite directions, while all clamping members along the second path Y rotate in the same direction. In this example, there are an even number of clamping members along the first path X. The mating parts of the transmission belt 22 that contact the rotating mating part of the first clamping member 121 and the mating parts of the transmission belt 22 that contact the rotating mating part of the second clamping member 122 are both located between the first clamping member 121 and the second clamping member 122.

[0037] In this example, the design principle of the maintenance device for the splitting roller simulates the rotation principle of the splitting roller in the texturing machine. By fixing the shaft of the splitting roller, the power unit of the drive component, such as a motor, controls the rotation speed when energized, for example, 300 rpm, 600 rpm, or 900 rpm. Each motor drives the array of two rows of clamping members, which in turn drives the two rows of splitting rollers. Through the transmission belt, such as a rubber belt, the clamping members rotate, which in turn drives the shaft of the splitting roller to rotate. The rotation time can be set as needed, for example, 30 seconds per rotation. The high-speed rotation allows the lubricating grease to quickly enter the interior of the splitting roller for effective lubrication, improving the lubrication effect. The unique one-to-many setting of this invention makes the lubrication effect of the splitting roller uniform and can achieve better lubrication effect, ensuring normal production after installation.

[0038] In summary, this invention uses the same transmission belt to drive all clamping components (with the wire splitting shaft set on the clamping components for synchronous movement), and ensures that any two adjacent clamping components in the same row of the first path rotate in opposite directions; in the same column of the second path, all clamping components rotate in the same direction. This ensures that each shaft starts and stops synchronously, rotates at the same speed, and travels in both forward and reverse directions, so that the grease in each independent cavity undergoes consistent shear-time conditions, thereby improving batch uniformity. Furthermore, by realizing forward / reverse rotation of adjacent shafts, the process can adopt forward and reverse grease-evening circulation, breaking the axial aggregation and dead zone retention caused by unidirectional shearing in the vertical cavity, and promoting the full spreading and wetting of the grease after application. Although the grease paths between multiple shafts are not interconnected, a smooth start-stop impact can be achieved through weak coupling via belts. For example, if the initial grease dispersion of one or more split shafts is uneven, or even biased to one side, the start and stop of each split shaft can be mutually restrained by the same transmission belt, making the start and stop of all split shafts tend to be balanced and smooth. By controlling sufficient rotation time, the severe unidirectional shearing effect caused by the independent start of a single split shaft can be greatly reduced, which causes the grease to be thrown to a local area. This is beneficial for the stable dispersion of high-viscosity grease and also helps to achieve batch-to-batch uniformity.
