Abstract

When yarn needs to be wound, a plurality of connecting rods are driven by an adjusting mechanism to move outwards at the same time and then are kept in a fixed state, so that the distance from a plurality of supporting arms to a rotating shaft is kept fixed, and the length of each circle is fixed when the yarn is wound; when yarn winding is completed and needs to be taken down, the multiple connecting rods are in a telescopic state through the adjusting mechanism, the multiple connecting rods stretch out and draw back to a certain degree under the gravity effect, the distances between the multiple supporting arms and the rotating shaft are reduced or unchanged, and the supporting arms located on the lower portion are still kept in a completely-stretching-out state under the gravity effect; and at the moment, multiple groups of wound yarns can be conveniently taken down.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of detection, in particular to a multifunctional sliver length measuring machine. BACKGROUND

[0002] The sliver length measuring machine is mainly used for measuring the linear density (count) and the sliver strength of the yarn. Its functions are as follows: (1) by shaking a certain number of yarns, the total length is calculated according to the number of turns and the length of a single turn, and then the linear density is calculated in combination with the weight; (2) preparing a strength sample for testing the breaking strength and other properties of the yarn.

[0003] For example, the Chinese patent with the authorization announcement number CN205561794U and the authorization announcement date of September 7, 2016 discloses a sliver length measuring machine. By sliding the sliding block towards the rotating shaft, the two segments of the stand are exposed. By folding the stand inwards or outwards, the straight-line distance between the length measuring rod and the rotating shaft is reduced, thereby facilitating the removal of the yarn after the length measurement is completed.

[0004] The sliver length measuring machine can simultaneously wind a plurality of yarns for subsequent calculation and averaging. However, in the above-mentioned comparative patent, after folding the stand inwards or outwards, it cannot be fixed. At this time, one hand needs to apply force to the stand, and the other hand needs to remove the yarn, thereby making the operation of removing the yarn very inconvenient. SUMMARY

[0005] The purpose of the present application is to provide a multifunctional sliver length measuring machine which has the function of facilitating the removal of the yarn.

[0006] The above technical purpose of the present application is achieved by the following technical scheme: a multifunctional sliver length measuring machine, comprising a base, a machine box arranged on the rear side of the base, a first guide frame arranged on the left side of the base and through which the yarn passes, a tensioner arranged on the left side of the machine box and through which the yarn passes, a second guide frame arranged in the middle of the machine box and through which the yarn passes, a yarn frame device rotatably connected to the right side of the machine box and used for winding the yarn, the yarn frame device comprising a rotating shaft rotatably connected to the machine box, a drive motor arranged in the machine box and driving the rotating shaft, a plurality of connecting rods arranged in a circumferential array at the front and rear ends of the rotating shaft, a plurality of support arms arranged between the front and rear connecting rods and through which the yarn is connected and wound, and an adjusting mechanism arranged in the rotating shaft, one end of the connecting rod being telescopically arranged on the rotating shaft and not falling off, the adjusting mechanism being used for driving the plurality of connecting rods to move outwardly and then remain in a fixed state or allowing the plurality of connecting rods to be in a telescopic state, and the operating part of the adjusting mechanism protruding out of the rotating shaft.

[0007] By adopting the above technical solution, when it is necessary to wind the yarn, the adjustment mechanism drives multiple connecting rods to move outward simultaneously and then remain in a fixed state, so that the distance from multiple support arms to the rotating shaft remains fixed, thus ensuring that the length of each turn of the yarn is fixed during winding. When the yarn winding is completed and needs to be removed, the adjustment mechanism makes multiple connecting rods in a telescopic state. Under the action of gravity, the multiple connecting rods extend and retract to a certain extent, so that the distance from multiple support arms to the rotating shaft decreases or remains unchanged (the support arm located at the bottom remains fully extended under the action of gravity). At this time, it is convenient to remove multiple sets of wound yarn.

[0008] A further configuration of the present invention is as follows: two annular connecting covers, respectively fixed to the front and rear ends of the rotating shaft by screws, are telescopically provided on the rotating shaft. Each annular connecting cover has a plurality of threaded holes arranged in a circumferential array. A threaded adjusting sleeve with a telescopic hole for one end of a connecting rod to pass through is threadedly connected to each threaded hole. A limiting ball is provided at the end of the connecting rod passing through the telescopic hole to prevent the connecting rod from falling off. The rotating shaft is hollow, and a connecting hole is provided on the rotating shaft corresponding to the limiting ball. When the threaded adjusting sleeve is fully tightened towards the direction close to the rotating shaft, the adjusting threaded sleeve drives the limiting ball to partially pass through the connecting hole; the adjusting... The mechanism acts on the limiting ball to drive multiple connecting rods to move outward simultaneously and then remain fixed. The operation steps for installing the connecting rods on the rotating shaft are as follows: (S1) One end of the connecting rod passes through the telescopic hole of the threaded adjusting sleeve, and the limiting ball is installed at the end of the connecting rod that passes through the telescopic hole. The position of the threaded adjusting sleeve is adjusted so that the limiting ball can be hidden on the annular connecting cover. Multiple connecting rods are installed one by one. (S2) The annular connecting cover is telescopically set on the rotating shaft and fixed by screws after it is moved into place. (S3) The threaded adjusting sleeve is fully tightened in the direction close to the rotating shaft, and the threaded adjusting sleeve drives the limiting ball to partially pass through the connecting hole.

[0009] By adopting the above scheme, the operation steps for installing the connecting rod on the rotating shaft are as follows: (S1) One end of the connecting rod passes through the telescopic hole of the threaded adjusting sleeve, a limiting ball is installed at the end of the connecting rod that passes through the telescopic hole, and the position of the threaded adjusting sleeve is adjusted so that the limiting ball can be hidden on the annular connecting cover. Multiple connecting rods are installed one by one; (S2) The annular connecting cover is telescopically set on the rotating shaft and fixed by screws after it is moved into place; (S3) The threaded adjusting sleeve is fully tightened in the direction close to the rotating shaft, and the threaded adjusting sleeve drives the limiting ball to partially pass through the connecting hole. In this process, the relative telescopic setting of the connecting rod and the rotating shaft and the function of preventing the connecting rod from falling off are solved; at the same time, with the adjustment of the threaded adjusting sleeve, the limiting ball at the end of the connecting rod will not interfere with the circumference of the rotating shaft during the installation process, so that the limiting ball can partially pass through the connecting hole after installation, so as to facilitate the adjustment mechanism set in the rotating shaft to apply the action of the limiting ball.

[0010] A further configuration of the present invention is as follows: the adjustment mechanism includes a first anti-detachment end cap disposed at the end of the rotating shaft, a threaded shaft threadedly connected to the first anti-detachment end cap, a first adjustment handwheel disposed at the end of the threaded shaft outside the rotating shaft, and a drive shaft disposed at the end of the threaded shaft inside the rotating shaft; the drive shaft is provided with two first annular grooves corresponding to two limiting balls respectively, the depth of the first annular grooves gradually increasing towards the direction closer to the chassis; in the initial state, the limiting balls abut against the circumference of the drive shaft, so that the connecting rod remains in a fixed state; during the rotation of the threaded shaft away from the chassis, the limiting balls gradually fall within the range of the first annular grooves, so that the connecting rod is in a telescopic state.

[0011] By adopting the above technical solution, in the initial state, the limiting ball is pressed against the circumference of the drive shaft, so that the connecting rod remains in a fixed state; as the threaded shaft rotates away from the chassis, the limiting ball gradually falls into the range of the first annular inclined groove, so that the connecting rod is in a telescopic state; finally, the adjustment mechanism can realize the function of driving multiple connecting rods to move outward simultaneously and then keeping them in a fixed state or making multiple connecting rods in a telescopic state.

[0012] A further configuration of the present invention is as follows: the adjustment mechanism includes a first spring embedded in the rotating shaft, a telescopic shaft telescopically disposed within the rotating shaft, a second anti-detachment end cap disposed at the end of the rotating shaft, a pressing rod disposed on the telescopic shaft and passing through the second anti-detachment end cap, a pressing cover disposed on the pressing rod, and an adsorption assembly disposed between the end of the telescopic shaft near the first spring and the chassis, which can be adsorbed and fixed after the first spring is compressed; the first spring drives the telescopic shaft to move toward the direction near the second anti-detachment end cap, and the telescopic shaft is provided with two second annular grooves with two corresponding limiting balls, the depth of the second annular grooves gradually decreasing toward the direction near the chassis; in the initial state, the limiting balls abut against the periphery of the drive shaft, so that the connecting rod remains fixed; during the pressing of the pressing cover toward the direction near the chassis, the first spring is compressed, and the limiting balls gradually fall into the range of the second annular grooves, so that the connecting rod is in a telescopic state, and the adsorption assembly gradually adsorbs; when the pressing of the pressing cover is released, the adsorption assembly first maintains the adsorption state and then gradually separates under the action of the first spring, and the first spring drives the telescopic shaft to reset.

[0013] By adopting the above technical solution, when it is necessary to remove the wound yarn, the pressing cover is pressed towards the direction of the machine housing. During this process, the first spring is compressed, and the limiting ball gradually falls into the range of the second annular inclined groove, so that the connecting rod is in a telescopic state. At the same time, when the pressing cover is released, the adsorption component first maintains the adsorption state and then gradually separates under the action of the first spring. The first spring drives the telescopic shaft to reset, so as to allow enough time to remove multiple sets of wound yarn. In addition, when the adsorption component is fixed to restrict the rotation of the shaft, the wound yarn is cut to avoid the problem of error in the number of turns of yarn winding due to the accidental rotation of the shaft.

[0014] A further feature of the present invention is that the circumference of the rotating shaft is provided with a plurality of waist-shaped holes extending along its length direction, and the adsorption assembly includes an annular plastic plate disposed on the chassis and surrounding the rotating shaft, a support rod with one end threaded to the telescopic shaft and the other end passing through the waist-shaped hole, and a flexible suction cup disposed at the end of the support rod passing through the waist-shaped hole and facing the annular plastic plate. During the movement of the telescopic shaft toward the direction closer to the chassis, the flexible suction cup adsorbs onto the annular plastic plate.

[0015] By adopting the above technical solution, as the telescopic shaft moves toward the direction closer to the chassis, the flexible suction cup adheres to the annular plastic plate to overcome the elastic force of the first spring and fix the telescopic shaft; at the same time, under the continuous action of the first spring, the flexible suction cup and the annular plastic plate will gradually separate, thereby achieving reset after maintaining the adhesion for a period of time, during which the wound yarn can be removed.

[0016] A further configuration of the present invention is as follows: a total of six support arms are provided; the adjustment mechanism includes a rotating shaft disposed within a rotating shaft, a third anti-detachment end cap disposed at the end of the rotating shaft away from the chassis, a protruding shaft disposed at one end of the rotating shaft and extending through the third anti-detachment end cap, a second adjustment handwheel disposed on the protruding shaft, and a limiting structure disposed between the protruding shaft and the third anti-detachment end cap; the rotating shaft is provided with multiple arc-shaped grooves arranged in a circumferential array at the corresponding limiting ball position; in the initial state, the limiting ball abuts against the circumference of the rotating shaft, so that the connecting rod remains in a fixed state; during the rotation of the rotating shaft... The limiting ball gradually falls within the area of ​​the arc-shaped groove, making the connecting rod in a telescopic state; as the rotating shaft continues to rotate, the limiting ball abuts against the circumference of the rotating shaft; in the initial state, the limiting ball abuts against the circumference of the rotating shaft, keeping the connecting rod in a fixed state; when the rotating shaft rotates 30 degrees, the limiting ball corresponds to the arc-shaped groove, making the connecting rod in a telescopic state; when the rotating shaft continues to rotate 30 degrees, the limiting ball abuts against the circumference of the rotating shaft again; every time the rotating shaft rotates 30 degrees, the limiting structure limits the rotation shaft.

[0017] By adopting the above technical solution, when it is necessary to remove the wound yarn, the second adjusting handwheel is turned to drive the rotating shaft to rotate. When the rotating shaft rotates 30 degrees, the limiting structure limits the rotating shaft, and the limiting ball corresponds to the arc groove, so that the connecting rod is in a telescopic state to facilitate the removal of the wound yarn. When the rotating shaft continues to rotate 30 degrees, the limiting ball is pressed against the circumference of the rotating shaft again, so that the connecting rod remains in a fixed state.

[0018] A further configuration of the present invention is as follows: the limiting structure includes a regular hexagonal portion disposed on the protruding shaft and a metal spring sheet disposed on the third anti-detachment end cap and in the shape of a "U"; the two sides of the metal spring sheet are used to abut against the two corresponding sides of the regular hexagonal portion, and in this state, the limiting ball abuts against the circumference of the rotating shaft; the two sides of the metal spring sheet are provided with recessed portions in the middle, and when the rotating shaft rotates 30 degrees from the state of abutting against the two corresponding sides of the regular hexagonal portion, the bend of the regular hexagonal portion can be embedded in the recessed portion for positioning.

[0019] By adopting the above technical solution, the limiting structure includes a regular hexagonal portion disposed on the protruding shaft and a metal spring piece in the shape of a "U" disposed on the third anti-detachment end cap; the two sides of the metal spring piece are used to abut against the two corresponding sides of the regular hexagonal portion, and in this state, the limiting ball abuts against the circumference of the rotating shaft; the two sides of the metal spring piece are provided with recessed portions in the middle, and when the rotating shaft rotates 30 degrees from the state of abutting against the two corresponding sides of the regular hexagonal portion, the bend of the regular hexagonal portion can be embedded in the recessed portion for positioning; finally, when the connecting rod is in the fixed state, the two sides of the metal spring piece are used to abut against the two corresponding sides of the regular hexagonal portion, and the limiting structure can stably restrict the rotation of the rotating shaft; when the connecting rod is in the telescopic state, the limiting structure provides slight limiting through the recessed portion, thereby facilitating the switching of the state of the two sides of the metal spring piece abutting against the two corresponding sides of the regular hexagonal portion.

[0020] A further feature of the present invention is that a second spring is provided at one end of the connecting rod that passes through the telescopic hole, and the two ends of the second spring are pressed between the threaded adjusting sleeve and the limiting ball. When the threaded adjusting sleeve is fully tightened, the second spring is in a compressed state.

[0021] By adopting the above technical solution, when the connecting rod is in the telescopic state, the stability of the connecting rod can be increased by setting a second spring, so that the limiting ball at the end of the connecting rod can be kept pressed against the annular limiting groove when it is in the holding position, ensuring that the distance between the connecting rod and the rotating shaft is reduced, so as to facilitate the removal of the wound yarn.

[0022] A further configuration of the present invention is as follows: a limiting seat is rotatably connected to the lower part of the first guide frame via a bearing; a limiting rod is provided on the limiting seat; a first annular airbag is provided on the upper surface of the limiting seat; a second annular airbag is provided around the periphery of the limiting rod; a connecting pipe is provided between the first annular airbag and the second annular airbag; a yarn bobbin is used to be sleeved on the limiting rod and rested on the limiting seat; when the bottom of the yarn bobbin rests on the limiting seat, the air in the first annular airbag is compressed and enters the second annular airbag, and the second annular airbag abuts against the inner wall of the yarn bobbin.

[0023] By adopting the above technical solution, when the bottom of the yarn bobbin is placed on the limiting seat, the air in the first annular airbag is compressed and enters the second annular airbag. The second annular airbag presses against the inner wall of the yarn bobbin to improve the stability of the yarn bobbin after installation and reduce shaking.

[0024] The beneficial effects of this invention are as follows: When it is necessary to wind the yarn, the adjustment mechanism drives multiple connecting rods to move outward simultaneously and then remain in a fixed state, so that the distance from multiple support arms to the rotating shaft remains fixed, thereby fixing the length of each turn of the yarn during winding; when the yarn winding is completed and needs to be removed, the adjustment mechanism makes multiple connecting rods in a telescopic state, and the multiple connecting rods extend and retract to a certain extent under the action of gravity, so that the distance from multiple support arms to the rotating shaft decreases or remains unchanged (the support arm located at the bottom remains fully extended under the action of gravity), which makes it convenient to remove multiple sets of wound yarn.

[0028] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] Example 1: A multifunctional yarn length measuring machine, such as Figure 1As shown, it includes a base 1, a housing 2 located on the rear side of the base 1, a first guide frame 3 located on the left side of the base 1 for the yarn to pass through, a tensioner 4 located on the left side of the housing 2 for the yarn to pass through, a second guide frame 5 located in the middle of the housing 2 for the yarn to pass through, and a yarn frame device 6 rotatably connected to the right side of the housing 2 for winding the yarn.

[0030] like Figure 1 and Figure 2 As shown, the yarn frame device 6 includes a rotating shaft 61 rotatably connected to the housing 2, a drive motor 62 disposed inside the housing 2 and driving the rotating shaft 61 to rotate, multiple connecting rods 63 arranged in a circumferential array at the front and rear ends of the rotating shaft 61, multiple support arms 64 disposed between the front and rear connecting rods 63 and for winding the yarn after connection, and an adjustment mechanism 65 disposed inside the rotating shaft 61. One end of the connecting rod 63 is telescopically mounted on the rotating shaft 61 and will not fall off. The adjustment mechanism 65 is used to drive multiple connecting rods 63 to move outward simultaneously and then maintain a fixed state or to make multiple connecting rods 63 in a telescopic state. The operating part of the adjustment mechanism 65 protrudes from the rotating shaft 61.

[0031] like Figures 2 to 5 As shown, two annular connecting covers 66 are telescopically mounted on the rotating shaft 61 and are respectively fixed to the front and rear ends of the rotating shaft 61 by screws. The annular connecting covers 66 are provided with multiple threaded holes 661 arranged in a circumferential array. The threaded holes 661 are threadedly connected to threaded adjusting sleeves 67 with telescopic holes 671 through which one end of the connecting rod 63 passes. The end of the connecting rod 63 that passes through the telescopic hole 671 is provided with a limiting ball 68 to prevent the connecting rod 63 from falling off. The rotating shaft 61 is hollow and has a connecting hole 611 corresponding to the limiting ball 68. When the threaded adjusting sleeve 67 is fully tightened in the direction close to the rotating shaft 61, the adjusting threaded sleeve drives the limiting ball 68 to partially pass through the connecting hole 611. The adjusting mechanism 65 acts on the limiting ball 68 to drive multiple connecting rods 63 to move outward simultaneously and then maintain a fixed state. The operation steps for mounting the connecting rod 63 on the rotating shaft 61 are as follows: (S1) One end of the connecting rod 63 passes through the telescopic hole 671 of the threaded adjusting sleeve 67, and a limiting ball 68 is installed at the end of the connecting rod 63 that passes through the telescopic hole 671. The position of the threaded adjusting sleeve 67 is adjusted so that the limiting ball 68 can be hidden on the annular connecting cover 66. Multiple connecting rods 63 are installed one by one; (S2) The annular connecting cover 66 is telescopically mounted on the rotating shaft 61 and fixed with screws after it is moved into place; (S3) The threaded adjusting sleeve 67 is fully tightened in the direction close to the rotating shaft 61, and the threaded adjusting sleeve 67 drives the limiting ball 68 to partially pass through the connecting hole 611.

[0032] like Figures 2 to 5As shown, the adjustment mechanism 65 includes a first anti-detachment end cap 6511 disposed at the end of the rotating shaft 61, a threaded shaft 6512 threadedly connected to the first anti-detachment end cap 6511, a first adjustment handwheel 6513 disposed at the end of the threaded shaft 6512 outside the rotating shaft 61, and a drive shaft 6514 disposed at the end of the threaded shaft 6512 inside the rotating shaft 61. The drive shaft 6514 is provided with two first annular grooves 65141 corresponding to two limiting balls 68 respectively. The depth of the first annular grooves 65141 gradually increases towards the direction closer to the chassis 2. In the initial state, the limiting balls 68 are pressed against the periphery of the drive shaft 6514, so that the connecting rod 63 remains in a fixed state. During the rotation of the threaded shaft 6512 away from the chassis 2, the limiting balls 68 gradually fall into the range of the first annular grooves 65141, so that the connecting rod 63 is in a telescopic state.

[0033] like Figure 4 and Figure 5 As shown, a second spring 6515 is provided at one end of the connecting rod 63 that passes through the telescopic hole 671. The two ends of the second spring 6515 are pressed between the threaded adjusting sleeve 67 and the limiting ball 68. When the threaded adjusting sleeve 67 is fully tightened and the limiting ball 68 is located at any position of the first annular inclined groove 65141, the second spring 6515 is in a compressed state.

[0034] like Figure 1 As shown, the lower part of the first guide frame 3 is rotatably connected to the limiting seat 71 via a bearing (not marked in the figure). The limiting seat 71 is provided with a limiting rod 72. The upper surface of the limiting seat 71 is provided with a first annular airbag 73. The periphery of the limiting rod 72 is provided with a second annular airbag 74. A connecting pipe 75 is provided between the first annular airbag 73 and the second annular airbag 74. The yarn bobbin is used to be sleeved on the limiting rod 72 and rested on the limiting seat 71. When the bottom of the yarn bobbin rests on the limiting seat 71, the air in the first annular airbag 73 is compressed and enters the second annular airbag 74. The second annular airbag 74 presses against the inner wall of the yarn bobbin.

[0035] Implementation effect: When it is necessary to wind the yarn, the adjustment mechanism 65 drives multiple connecting rods 63 to move outward simultaneously and then remain fixed, so that the distance between multiple support arms 64 and the rotating shaft 61 remains fixed, thus ensuring that the length of each turn of the yarn is fixed during winding. When the yarn winding is completed and needs to be removed, the adjustment mechanism 65 makes multiple connecting rods 63 in a telescopic state. Under the action of gravity, multiple connecting rods 63 extend and retract to a certain extent, so that the distance between multiple support arms 64 and the rotating shaft 61 decreases or remains unchanged (the lower support arm 64 remains fully extended under the action of gravity). At this time, it is convenient to remove multiple sets of wound yarn.

[0036] The steps for installing connecting rod 63 on rotating shaft 61 are as follows: (S1) One end of connecting rod 63 passes through the telescopic hole 671 of threaded adjusting sleeve 67, a limiting ball 68 is installed at the end of connecting rod 63 passing through telescopic hole 671, and the position of threaded adjusting sleeve 67 is adjusted so that the limiting ball 68 can be hidden on annular connecting cover 66. Multiple connecting rods 63 are installed one by one; (S2) Annular connecting cover 66 is telescopically mounted on rotating shaft 61 and fixed with screws after being moved into place; (S3) The threaded adjusting sleeve 67 is oriented towards the rotating shaft 61. When shaft 61 is fully tightened, threaded adjusting sleeve 67 drives limiting ball 68 to partially pass through connecting hole 611. In this process, the relative extension and retraction of connecting rod 63 and rotating shaft 61 is resolved, and the function of preventing connecting rod 63 from falling off is also resolved. At the same time, with the adjustment of threaded adjusting sleeve 67, the limiting ball 68 at the end of connecting rod 63 will not interfere with the circumference of rotating shaft 61 during installation. This allows the limiting ball 68 to partially pass through connecting hole 611 after installation, so that the adjusting mechanism 65 set in rotating shaft 61 can apply force to the limiting ball 68.

[0037] In the initial state, the limiting ball 68 abuts against the circumference of the drive shaft 6514, keeping the connecting rod 63 in a fixed state. As the threaded shaft 6512 rotates away from the housing 2, the limiting ball 68 gradually falls into the range of the first annular inclined groove 65141, making the connecting rod 63 in a telescopic state. Finally, the adjusting mechanism 65 can be used to drive multiple connecting rods 63 to move outward simultaneously and then keep them in a fixed state or to keep multiple connecting rods 63 in a telescopic state. When the connecting rod 63 is in the telescopic state, the stability of the connecting rod 63 can be increased by setting a second spring 6515, so that the limiting ball 68 at the end of the connecting rod 63 can remain abutted against the annular limiting groove when it is in action, ensuring that the distance between the connecting rod 63 and the rotating shaft 61 is reduced, so as to facilitate the removal of the wound yarn.

[0038] When the yarn bobbin is placed on the limiting seat 71 at the bottom, the air in the first annular airbag 73 is compressed and enters the second annular airbag 74. The second annular airbag 74 presses against the inner wall of the yarn bobbin to improve the stability of the yarn bobbin after installation and reduce shaking.

[0039] Example 2: A multifunctional yarn length measuring machine, such as Figures 6 to 8As shown, the difference from Embodiment 1 lies in the adjustment mechanism 65. The adjustment mechanism 65 includes a first spring 6521 embedded in the rotating shaft 61, a telescopic shaft 6522 telescopically disposed in the rotating shaft 61, a second anti-detachment end cap 6523 disposed at the end of the rotating shaft 61, a pressing rod 6524 disposed on the telescopic shaft 6522 and passing through the second anti-detachment end cap 6523, a pressing cover 6525 disposed on the pressing rod 6524, and an adsorption component 6526 disposed between the end of the telescopic shaft 6522 near the first spring 6521 and the housing 2, which can be adsorbed and fixed after the first spring 6521 is compressed.

[0040] like Figures 6 to 8 As shown, the first spring 6521 drives the telescopic shaft 6522 to move towards the direction of the second anti-detachment end cover 6523. The telescopic shaft 6522 is provided with two second annular grooves 65221 corresponding to two limiting balls 68 at two different locations. The depth of the second annular grooves 65221 gradually decreases towards the direction of the chassis 2. In the initial state, the limiting balls 68 are pressed against the periphery of the drive shaft 6514, so that the connecting rod 63 remains fixed. During the pressing of the pressing cover 6525 towards the direction of the chassis 2, the first spring 6521 is compressed by force, and the limiting balls 68 gradually fall into the range of the second annular grooves 65221, so that the connecting rod 63 is in a telescopic state, and the adsorption component 6526 gradually adsorbs. When the pressing of the pressing cover 6525 is released, the adsorption component 6526 first maintains the adsorption state and then gradually separates under the action of the first spring 6521, and the first spring 6521 drives the telescopic shaft 6522 to reset.

[0041] like Figures 6 to 9 As shown, the circumference of the rotating shaft 61 is provided with a plurality of waist-shaped holes 612 extending along its length direction. The adsorption assembly 6526 includes an annular plastic plate 65261 disposed on the housing 2 and surrounding the rotating shaft 61, a support rod 65262 with one end threaded to the telescopic shaft 6522 and the other end passing through the waist-shaped hole 612, and a flexible suction cup 65263 disposed at one end of the support rod 65262 passing through the waist-shaped hole 612 and facing the annular plastic plate 65261. During the movement of the telescopic shaft 6522 toward the direction closer to the housing 2, the flexible suction cup 65263 adsorbs onto the annular plastic plate 65261.

[0042] Implementation effect: When it is necessary to remove the wound yarn, press the pressing cover 6525 towards the direction of the machine housing 2. During this process, the first spring 6521 is compressed, and the limiting ball 68 gradually falls into the range of the second annular inclined groove 65221, so that the connecting rod 63 is in a telescopic state. At the same time, when the pressing cover 6525 is released, the adsorption component 6526 first maintains the adsorption state and then gradually separates under the action of the first spring 6521. The first spring 6521 drives the telescopic shaft 6522 to reset, so as to allow enough time to remove multiple sets of wound yarn. In addition, when the adsorption component 6526 is fixed to restrict the rotation of the rotating shaft 61, the wound yarn is cut to avoid the problem of error in the number of turns of yarn winding due to the misrotation of the rotating shaft 61. As the telescopic shaft 6522 moves toward the housing 2, the flexible suction cup 65263 adheres to the annular plastic plate 65261 to overcome the elastic force of the first spring 6521 and fix the telescopic shaft 6522. At the same time, under the continuous action of the first spring 6521, the flexible suction cup 65263 and the annular plastic plate 65261 will gradually separate, thereby achieving reset after maintaining the adhesion for a period of time. During this process, the wound yarn can be removed.

[0043] Example 3: A multifunctional yarn length measuring machine, such as Figures 10 to 12 As shown, the difference from Embodiment 1 lies in the adjustment mechanism 65. A total of six support arms 64 are provided. The adjustment mechanism 65 includes a rotating shaft 6531 disposed within the rotating shaft 61, a third anti-detachment end cap 6532 disposed at the end of the rotating shaft 61 away from the housing 2, a protruding shaft 6533 disposed at one end of the rotating shaft 6531 and extending through the third anti-detachment end cap 6532, a second adjustment handwheel 6534 disposed on the protruding shaft 6533, and a limiting structure 6535 disposed between the protruding shaft 6533 and the third anti-detachment end cap 6532. The rotating shaft 6531 has multiple arc-shaped grooves 65311 arranged in a circular array at the corresponding limiting ball 68. In the initial state, the limiting ball 68 is pressed against the circumference of the rotating shaft 6531, so that the connecting rod 63 remains fixed. During the rotation of the rotating shaft 6531, the limiting ball 68 gradually falls into the range of the arc-shaped grooves 65311, so that the connecting rod 63 is in a telescopic state. During the continued rotation of the rotating shaft 6531, the limiting ball 68 is pressed against the circumference of the rotating shaft 6531. In the initial state, the limiting ball 68 is pressed against the circumference of the rotating shaft 6531, keeping the connecting rod 63 in a fixed state; when the rotating shaft 6531 rotates 30 degrees, the limiting ball 68 corresponds to the arc groove, making the connecting rod 63 in a telescopic state; when the rotating shaft 6531 continues to rotate 30 degrees, the limiting ball 68 is pressed against the circumference of the rotating shaft 6531 again; every time the rotating shaft 6531 rotates 30 degrees, the limiting structure 6535 limits the rotation shaft 6531.

[0044] likeFigure 11 and Figure 12 As shown, the limiting structure 6535 includes a regular hexagonal portion 65351 disposed on the protruding shaft 6533 and a metal spring piece 65352 disposed on the third anti-detachment end cap 6532 and shaped like the letter "U". The two sides of the metal spring piece 65352 are used to abut against the two corresponding sides of the regular hexagonal portion 65351. In this state, the limiting ball 68 abuts against the circumference of the rotating shaft 6531. The two sides of the metal spring piece 65352 are provided with recessed portions 653521. When the rotating shaft 6531 rotates 30 degrees from the state of abutting against the two corresponding sides of the regular hexagonal portion, the bend of the regular hexagonal portion 65351 can be embedded in the recessed portion 653521 for positioning.

[0045] Implementation effect: When it is necessary to remove the wound yarn, the second adjusting handwheel 6534 is turned to drive the rotating shaft 6531 to rotate. When the rotating shaft 6531 rotates 30 degrees, the limiting structure 6535 limits the rotating shaft 6531, and the limiting ball 68 corresponds to the arc groove, so that the connecting rod 63 is in a telescopic state to facilitate the removal of the wound yarn; when the rotating shaft 6531 continues to rotate 30 degrees, the limiting ball 68 is pressed against the circumference of the rotating shaft 6531 again, so that the connecting rod 63 remains in a fixed state.

[0046] The limiting structure 6535 includes a regular hexagonal portion 65351 disposed on the protruding shaft 6533 and a metal spring piece 65352 in the shape of a "U" disposed on the third anti-detachment end cap 6532; the two sides of the metal spring piece 65352 are used to abut against the corresponding two sides of the regular hexagonal portion 65351. In this state, the limiting ball 68 abuts against the circumference of the rotating shaft 6531; the two sides of the metal spring piece 65352 are provided with recessed portions 653521. When the rotating shaft 6531 rotates 30 degrees from the state of abutting against the corresponding two sides of the regular hexagonal portion 65351, the limiting ball 65352 is used to abut against the circumference of the rotating shaft 6531. The corner of the hexagonal portion 65351 can be embedded in the recessed portion 653521 for positioning; finally, when the connecting rod 63 is in the fixed state, the two sides of the metal spring 65352 are used to abut against the two corresponding sides of the regular hexagonal portion 65351, and the limiting structure 6535 can stably restrict the rotation of the rotating shaft 6531. When the connecting rod 63 is in the telescopic state, the limiting structure 6535 performs slight limiting through the recessed portion 653521, thereby facilitating the switching of the state in which the two sides of the metal spring 65352 abut against the two corresponding sides of the regular hexagonal portion 65351.
