Description

Technical Field

[0001] The invention belongs to the technical field of fiber detection, and in particular relates to a device for detecting the fibrillation degree of lyocell fibers. Background Art

[0002] Lyocell is a regenerated cellulose fiber, and its production process involves dissolving the cellulose in wood pulp and re-spinning it. Fibrillation refers to the phenomenon that during wet treatment, friction or washing of Lyocell fiber, the fine fibers on the fiber surface loosen and stretch out, forming a fluff-like structure. This phenomenon may cause the fabric to feel worse, become less smooth, and appear to have slight pilling. It may also increase the cohesion between fibers, affecting the appearance and texture of the textile.

[0003] Therefore, in order to ensure product quality and optimize the production and processing process, it is very important to test the fibrillation degree of Lyocell fiber. Testing the fibrillation degree of Lyocell fiber can help adjust process parameters, guide subsequent processing based on data, and ensure that the product meets the expected quality standards. At the same time, the study and detection of fibrillation phenomenon can also contribute to the development of new materials and the exploration of new technologies, and promote the continuous optimization of Lyocell fiber performance and the expansion of new application areas.

Therefore, they cannot be understood as limitations on the present invention.

[0035] In addition, the terms "first", "second" and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] A device for detecting the fibrillation degree of lyocell fibers, such as Figure 1-Figure 5As shown, it includes: a frame 1, a fibrillation roller 2, a humidifier 3, a limiting roller 4 and a storage box 51. The fibrillation roller 2 for rubbing the lyocell fiber 01 is rotatably provided in the middle of the frame 1. The fibrillation roller 2 is driven to rotate by an external power source, and the power source is a driving motor. The humidifier 3 located directly above the fibrillation roller 2 is provided on the upper side of the middle of the frame 1. The humidification treatment of the humidifier 3 allows the lyocell fiber 01 on the upper side of the fibrillation roller 2 to be subjected to fibrillation degree detection in a wet state. The left and right sides of the frame 1 are provided with a limit roller 4 and a storage box 51. The highest point of the limit roller 4 is located between the highest point of the storage box 51 and the highest point of the fibrillation roller 2. The upper front side of the storage box 51 is equipped with a control console 50. The lyocell fiber 01 is placed on the upper side of the fibrillation roller 2 and the upper sides of the left and right limit rollers 4, and then the two ends of the lyocell fiber 01 are respectively stored in the two storage boxes 51, so that the external power source can be controlled to drive the fibrillation roller 2 to rotate. The lyocell fiber 01 is rubbed with the lyocell fiber 01 during rotation, so as to detect the fibrillation degree of the lyocell fiber 01 by comparing the surface roughness change of the lyocell fiber 01 during friction, comparing the fiber state before and after friction, and according to the time when the lyocell fiber 01 breaks, etc. The two storage boxes 51 are rotatably provided with door panels on the sides away from each other, a support seat 52 is provided in the storage box 51, a rotating shaft 53 is rotatably provided on the support seat 52, a stopper 54 is connected to the eccentric position of the front end of the rotating shaft 53, a semicircular notch is provided on the upper side of the rear part of the rotating shaft 53, a pressing shaft 55 suitable for cooperating with the rotating shaft 53 to form a full circle is slidably provided on the notch of the rotating shaft 53, the shape of the pressing shaft 55 is semicircular, and the front end of the pressing shaft 55 is connected to a sliding block 56 that slides through the upper part of the rotating shaft 53, when the end of the lyocell fiber 01 is stored in the storage box 51, the door panel on the storage box 51 is opened, and the end of the lyocell fiber 01 is passed between the pressing shaft 55 and the rotating shaft 53 (such as Figure 3 As shown in the figure, the pressing shaft 55 is driven downward by the sliding block 56 to press the Lyocell fiber 01 onto the rotating shaft 53, thereby fixing the end of the Lyocell fiber 01 and preventing the Lyocell fiber 01 from being separated from the rotating fibrillating roller 2. The pressing shaft 55 is driven to rotate by rotating the rotating shaft 53 to reel in the excess Lyocell fiber 01, and the Lyocell fiber 01 is prevented from constantly shifting and changing the friction position during the friction of the fibrillating roller 2, thereby ensuring the effective contact between the Lyocell fiber 01 and the fibrillating roller 2. The storage box 51 is provided with a servo motor 57, which is controlled by the console 50 to open and close. The servo motor 57 is embedded in the front lower part of the storage box 51. The output shaft of the servo motor 57 is connected with a plane spiral ring 58. The sliding block 56 is slidably matched in the spiral gap on the plane spiral ring 58. One side of the plane spiral ring 58 is connected with a shifting block 59 suitable for contacting and matching with the stopper 54. When the end of the lyocell fiber 01 is passed between the pressing shaft 55 and the rotating shaft 53 (such as Figure 3When the plane spiral ring 58 is rotated, the servo motor 57 is controlled to drive the plane spiral ring 58 to rotate and squeeze the sliding block 56 to move downward, and the sliding block 56 will drive the pressing shaft 55 to move downward to press the Lyocell fiber 01 on the rotating shaft 53, so as to realize automatic mounting. Then the plane spiral ring 58 continues to rotate and drives the shifting block 59 to push the stopper 54 to rotate. The stopper 54 will drive the rotating shaft 53 to rotate, and the rotating shaft 53 will drive the pressing shaft 55 to rotate synchronously with the plane spiral ring 58. Therefore, the pressing shaft 55 will stop squeezing the Lyocell fiber 01, and only pass By controlling the servo motor 57, the rotating shaft 53 and the pressing shaft 55 can be automatically and synchronously rotated to roll up the excess lyocell fiber 01 after clamping the end of the lyocell fiber 01, with a high degree of automation and synchronization. In addition, when the lyocell fiber 01 is broken by friction, the left and right servo motors 57 can be continuously controlled to drive the left and right rotating shafts 53 to rotate, so that the two broken lyocell fibers 01 can be respectively rolled up into the left and right storage boxes 51, thereby eliminating the need to manually pick up the broken lyocell fibers 01.

[0037] like Figure 1 , Figure 2 and Figure 6 As shown, it also includes: two left and right opposite electric guide rails 61 are installed on the frame 1, and a lifting frame 62 is connected to the slider of the electric guide rail 61, and an adjusting roller 63 is provided on the lifting frame 62. The left and right adjusting rollers 63 are respectively located on the left and right sides of the fibrillation roller 2, and the left and right adjusting rollers 63 are both located between the left and right limiting rollers 4. When the fibrillation degree of the Lyocell fiber 01 needs to be detected, the Lyocell fiber 01 is passed around the upper side of the fibrillation roller 2, the upper side of the left and right limiting rollers 4 and the lower side of the left and right adjusting rollers 63, and then the electric guide rail 61 is controlled to drive the lifting frame 62 to drive the adjusting roller 63 to rise and fall to adjust the height of the adjusting roller 63, so that by adjusting the downward pressure of the adjusting roller 63 on the Lyocell fiber 01, the contact between the Lyocell fiber 01 and the fibrillation roller 2 can be ensured, and the contact area between the Lyocell fiber 01 and the fibrillation roller 2 can be changed, so as to realize diversified fibrillation detection.

[0038] like Figure 6-Figure 8 As shown, it also includes: L-shaped sleeves 64 are connected to the front and rear center endpoints of the rotating shaft 53, and a connecting rod 65 is connected to the L-shaped sleeve 64. A limiting sleeve 66 for limiting the position around the lyocell fiber 01 is rotatably provided between the ends of the two adjacent front and rear connecting rods 65. The center of the limiting sleeve 66 corresponds to the midpoint of the axial center line of the hollow roller 631. L-shaped shaft rods 67 are connected to the front and rear center endpoints of the limiting roller 4. The front and rear L-shaped shaft rods 67 slide through the front and rear L-shaped sleeves 64 respectively. The bending angles of the L-shaped sleeves 64 and the L-shaped shaft rod 67 are both ninety degrees. Since the tangent of the circle is perpendicular to the radius passing through the tangent point, the slidingly matched L-shaped sleeves 64 and the L-shaped shaft rod 67 are equivalent to coinciding with the tangent between the limiting roller 4 and the adjusting roller 63 in the main view (as shown in FIG. Figure 2 As shown), when the Lyocell fiber 01 bypasses the upper side of the limiting roller 4 and the lower side of the adjusting roller 63, the Lyocell fiber 01 will be parallel to the L-shaped sleeve 64 and the L-shaped shaft rod 67, so that the limiting sleeve 66 corresponds to the Lyocell fiber 01, and when the Lyocell fiber 01 passes through the limiting sleeve 66, the limiting sleeve 66 can be used to limit the front and rear position of the Lyocell fiber 01 to prevent the Lyocell fiber 01 from being displaced in the front and rear directions. Even on the basis that the adjusting roller 63 can be raised and lowered, the restraint between the sliding-fitting L-shaped sleeve 64 and the L-shaped shaft rod 67 can be cleverly used to make the limiting sleeve 66 always correspond to the Lyocell fiber 01, and the various structures are interrelated and coordinated with each other. In another feasible solution, if the Lyocell fiber 01 to be tested for the degree of fibrillation is in sheet form, the limiting sleeve 66 and the middle opening thereof can be shaped into a long strip (as shown in FIG. 1 ). Figure 8 As shown), but in this embodiment, the shape of the limiting sleeve 66 is circular (as shown Figure 7 as shown).

[0039] like Figure 6 and Fig. 9 As shown, the adjusting roller 63 includes: a hollow roller 631 arranged on the frame 1, a cavity is opened on the hollow roller 631, and the cavity is located in the middle and lower part of the hollow roller 631. A pressure sensor 632 electrically connected to the control console 50 is installed at the position where the cavity is opened on the hollow roller 631. When the fibrillation degree of the lyocell fiber 01 is detected, a timer is used to calculate the time when the end of the lyocell fiber 01 is opened. When the pressure sensor 632 is subjected to pressure, the control console 50 controls the external timer to stop timing. Two left and right sliding rods are provided at the position where the cavity is opened on the hollow roller 631. The sliding rods 633 are opposite to each other, and a compression spring around the hollow roller 631 is connected between the sliding rods 633 and the hollow roller 631. A semicircular arc-shaped abutment plate 634 is connected between the lower ends of the two sliding rods 633. The arc-shaped abutment plate 634 is suitable for forming a full circle with the hollow roller 631. The inner arc surface of the arc-shaped abutment plate 634 is connected to an L-shaped pressing plate 635. The L-shaped pressing plate 635 is used to press the pressure sensor 632. The pressure sensor 632 is located between the L-shaped pressing plate 635 and the arc-shaped abutment plate 634. Initially, when the lyocell fiber 01 passes around the lower side of the adjusting roller 63 (such as Figure 6 As shown in the figure, the Lyocell fiber 01 will press the arc-shaped support plate 634 upwards, and the compression spring will be deformed. During the fibrillation degree detection, when the Lyocell fiber 01 is broken by the friction of the fibrillation roller 2, the arc-shaped support plate 634 will move down and reset under the action of the compression spring. The downward movement of the arc-shaped support plate 634 will drive the L-shaped pressure plate 635 to move down and squeeze the pressure sensor 632, so as to automatically and synchronously record after the Lyocell fiber 01 is broken. At this time, the pressure sensor 632 can also control the servo motor 57 through the control console 50 to drive the rotating shaft 53 to rotate and roll up the broken Lyocell fiber 01, which is easy to operate.

[0040] like Figure 10-Figure 14 As shown, the fibrillation roller 2 includes: a support shaft 21 rotatably arranged in the middle of the frame 1, a shaft roller 22 is sleeved on the support shaft 21, a friction sleeve 23 is slidably arranged on the shaft roller 22, and the friction sleeve 23 is used to rub the lyocell fiber 01. In order to diversify the detection, the friction sleeve 23 is designed to be made of different materials or with different roughness of the outer arc surface or with different patterns for friction of the outer arc surface according to the needs of the fibrillation degree detection, and the friction sleeve 23 on the shaft roller 22 can be slid out and replaced, which further realizes the diversification of the detection and is useful for understanding the fibrillation degree of the lyocell fiber 01 under different conditions. The first end and the second end of the support shaft 21 are respectively provided with a first ferrule 24 and a second ferrule 25, and the first ferrule 24 is detachably arranged on the support shaft 21. The first end of the shaft 21 and the second clamping sleeve 25 are fixedly connected to the second end of the support shaft 21. The second end of the support shaft 21 is driven to rotate by an external power source. The first clamping sleeve 24 and the second clamping sleeve 25 are respectively provided with a first clamping jaw group and a second clamping jaw group for clamping the friction sleeve 23 to the front and rear ends of the shaft roller 22. If the friction sleeve 23 needs to be replaced, the first clamping jaw group and the second clamping jaw group are first controlled to loosen the friction sleeve 23, and then the first clamping sleeve 24 together with the second clamping jaw group are removed from the support shaft 21. At this time, the friction sleeve 23 on the support shaft 21 can be replaced, and then the first clamping sleeve 24 together with the second clamping jaw group are reinstalled on the support shaft 21, and then the first clamping jaw group and the second clamping jaw group are controlled to clamp the friction sleeve 23 to the shaft roller 22.

[0041] like Fig.10 and Fig.11 As shown, it also includes: the first clamping sleeve 24 has an end cover 241 bolted thereto, the end cover 241 is slidably sleeved on the front end of the support shaft 21, the end cover 241 is connected with a circle of T-shaped block 242 slidably embedded in the front end of the support shaft 21, and a latch 211 is inserted between the end of the support shaft 21 and the T-shaped block 242. When the latch 211 is removed from the T-shaped block 242, the end cover 241 can be moved forward and drive the T-shaped block 242 and the first clamping sleeve 24 to be disassembled, thereby facilitating the replacement of the friction sleeve 23.

[0042] like Figure 12-14As shown, the second clamping jaw group includes: a gear ring 251 is rotatably arranged on the second clamping sleeve 25, and four gears 252 that mesh with the gear ring 251 are rotatably arranged on the second clamping sleeve 25, and three slide bars 253 are slidably arranged on the second clamping sleeve 25, and an electric push rod 254 is installed on the second clamping sleeve 25, and the telescopic rod and the slide bar 253 of the electric push rod 254 are connected to a fixed clamp block 255, and the fixed clamp block 255 is connected to a rack 266 that meshes with the gear 252, and the four racks 266 are meshed with the four gears 252 one by one, and when needed When the second clamping jaw group is controlled to clamp the friction sleeve 23 to the shaft roller 22, the electric push rod 254 is controlled to drive the fixed clamping block 255 connected thereto to move inward to clamp the friction sleeve 23. The inward-moving fixed clamping block 255 will drive the gear ring 251 to rotate through the engagement of the rack 266 and the gear 252. The rotation of the gear ring 251 will drive all the gears 252 to rotate and engage with the rack 266, thereby synchronously driving multiple fixed clamping blocks 255 to clamp synchronously, thereby improving the stability of the friction sleeve 23 and being able to clamp friction sleeves 23 of different diameters.

[0043] like Fig.10 , Fig.13 and Fig.14 As shown, the first clamping jaw group includes: the telescopic rod of the electric push rod 254 and the three sliding rods 253 are connected to the transmission rod 257 that slides through the shaft roller 22, and four sliding columns 243 are slidably provided on the end cover 241. The four sliding columns 243 correspond to the four transmission rods 257 one by one. The sliding column 243 has a ring sleeve portion 2431 that is slidably sleeved on the front end of the transmission rod 257. The sliding column 243 is connected to a movable clamping block 244, which will be removed from the support shaft 21 as the first clamping sleeve 24 is removed, thereby removing the restriction on the friction sleeve 23. The movable clamping block 244 and the fixed clamping block 255 are respectively located on the front and rear sides of the friction sleeve 23 and surround the inclined groove for the lyocell fiber 01 to pass through. When the fixed clamping block 255 is driven to move and clamp the friction sleeve 23, The telescopic rod of the electric push rod 254 will drive the sliding column 243 to move through the transmission rod 257 connected to it, and the movement of the sliding rod 253 will also drive the sliding column 243 to move through the transmission rod 257 connected to it. Therefore, when the electric push rod 254 drives all the fixed clamping blocks 255 to clamp the friction sleeve 23, all the sliding columns 243 will drive all the clamping blocks to move and clamp the friction sleeve 23; and when removing the first clamping sleeve 24, the annular sleeve portion 2431 on the sliding column 243 can be slid off the transmission rod 257 to remove the sliding column 243 from the transmission rod 257, so that disassembly can be achieved, and the clamping drive on both sides can be achieved only by one electric push rod 254, and the omitted power components can also reduce the weight of the first clamping sleeve 24, making disassembly and assembly convenient.

[0044] Obviously, the embodiments described above are only some embodiments of the present invention, rather than all embodiments. They only express the preferred implementation modes of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention.

[0045] It should be pointed out that, for ordinary technicians in this field, several modifications, increases and decreases in quantity, improvements and substitutions can be made without departing from the concept of the present invention. Therefore, based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.
