Description

Technical Field

[0001] This invention relates to the field of wool yarn quality testing technology, specifically to a quality testing device for wool yarn. Background Technology

[0002] Wool yarn is a type of yarn spun from wool and is widely used in the textile industry. It is soft, with tightly interlocked fibers, excellent warmth retention, can absorb one-third of its own weight in water, is non-flammable and fire-retardant, has good fiber elasticity, and its special scaly structure makes finished products durable. Wool yarn has a wide range of uses, mainly for hand-knitting and machine-weaving, and can be used to weave sweaters, trousers, scarves, and other clothing and accessories, providing both warmth and decoration. It is also used to weave industrial fabrics, stationery, and carpets. Currently, wool yarn requires testing during production, such as tension testing, twist testing, and appearance testing. Existing testing methods mostly rely on specialized equipment and require specialized personnel. Therefore, purchasing personnel often can only judge the quality of wool yarn based on data in reports and cannot directly observe its quality. Furthermore, wool yarn testing often involves multiple processes and takes a considerable amount of time, and purchasing personnel often need to compare multiple manufacturers, making it difficult to quickly determine the quality differences between various groups of wool yarn.

The drive gear 606 is rotatably installed on the rear side of the mounting base plate 1, and the drive gear 606 and the hollow gear 602 mesh.

[0036] The fixing mechanism 7 includes a third movable groove 701 and an extrusion cylinder 702. The fixing wheel 4 has a third movable groove 701, and the extrusion cylinder 702 is movably arranged in the third movable groove 701.

[0037] The counting drive mechanism 8 includes a mounting side plate 801 and an electronic counter 803. The mounting side plate 801 is located at the right end of the mounting base plate 1.

[0038] The observation mechanism 9 includes a magnifying lens 903 and a thread-pulling needle 910, both of which are movably mounted on the front side of the mounting base plate 1. This device, through the clamping mechanism 5 and the fixing mechanism 7, allows wool yarn to be wound at one end and rotated at the other, thereby achieving tension and twist testing. Furthermore, when using one function, the other function will not adversely affect it, increasing the convenience and stability of the equipment. The rotation of the winding wheel 2 and the fixing wheel 4 can be digitized, allowing for a more intuitive display of the wool yarn's test data, making it easier for users to judge the quality of the wool yarn. The device also includes an observation mechanism 9 to facilitate user observation of the wool yarn, increasing the functionality of the equipment.

[0039] Furthermore, the clamping mechanism 5 also includes an upward lifting block 502, a clamping block 504, an annular placement groove 505, a clamping groove 506, a first movable groove 507, a first movable block 508, a first guide hole 509, a first guide rod 510, and a compression spring 511.

A schematic diagram of this structure is shown below. Figure 3 This structure is used to clamp wool yarn. The yarn can be placed in the clamping groove 506 so that the clamping block 504 clamps it, or the wool yarn can be wound around the clamping block 504 and then fixed by the engagement between the clamping block 504 and the clamping groove 506, thereby achieving stable fixation.

[0040] Furthermore, the marking drive mechanism 6 also includes a length marking groove 603, a pointing block 604, and a counterweight block 605.

The counterweight block 605 is fixedly mounted on the lower side of the first connecting shaft 601. A schematic diagram of this structure is shown below. Figure 2 and Figure 3 The pointing block 604 is located in front of the length gauge groove 603, and the relative position of the length gauge groove 603 and the pointing block 604 can be clearly observed, so that the user can intuitively read the tension data of the wool yarn. The counterweight block 605 can facilitate the hollow gear 602 to be reset under the action of gravity, which increases the convenience of using the equipment.

[0041] Furthermore, the marking drive mechanism 6 also includes a first knob 607, a second connecting shaft 608, a ratchet 609, a mounting block 610, a mounting shaft 611, a mounting cylinder 612, a torsion spring 613, a first limiting piece 614, a second limiting piece 615, a limiting strip 616, a movable block 617, a second movable groove 618, a return spring 619, a limiting triangular block 620, a hollow button 621, a shielding frame 622, a first placement groove 623, a second placement groove 624, and a third placement groove 625. The second connecting shaft 608 is fixedly mounted on the drive gear 606. A ratchet 609 is fixedly mounted on the second connecting shaft 608. The thickness of the second connecting shaft 608 is greater than the thickness of the ratchet 609. A first knob 607 is fixedly mounted on the ratchet 609. A mounting block 610 is fixedly mounted on the mounting base plate 1. The mounting block 610 is located above the drive gear 606. A mounting shaft 611 is fixedly mounted on the mounting block 610. A mounting cylinder 612 is rotatably mounted on the mounting shaft 611. A torsion spring 613 is sleeved on the mounting shaft 611. One end of the torsion spring 613 is fixedly mounted on the mounting shaft 611, and the other end of the torsion spring 613... The end is fixedly installed inside the mounting cylinder 612. A first limiting piece 614 is fixedly installed on the mounting shaft 611. A second limiting piece 615 is fixedly installed inside the mounting cylinder 612, and the second limiting piece 615 abuts against the first limiting piece 614. Limiting strips 616 are fixedly installed in an array on the mounting cylinder 612. A movable round block 617 is sleeved on the mounting cylinder 612. A second movable groove 618 is opened in the movable round block 617. The shape of the second movable groove 618 is adapted to the shape of the mounting cylinder 612 and the limiting strips 616. A limiting triangular block 6 is fixedly installed on the lower side of the movable round block 617. 20. A limiting triangular block 620 engages with a ratchet 609. A return spring 619 is sleeved on the mounting cylinder 612. A hollow button 621 is fixedly mounted on the movable round block 617. A shielding frame 622 is fixedly mounted on the rear side of the mounting base plate 1. A first placement groove 623 and a second placement groove 624 are opened on the rear side of the shielding frame 622. A third placement groove 625 is opened on the left side of the shielding frame 622. The hollow button 621 is inserted into the second placement groove 624, the first knob 607 is inserted into the first placement groove 623, and the hollow gear 602 is inserted into the third placement groove 625. A schematic diagram of this structure is shown below. Figure 4 and Figure 5The component mounted on the mounting block 610 allows the limiting triangle block 620 to rotate in one direction and extend and retract. Unidirectional rotation restricts the rotation of the ratchet 609, while extension and retraction releases the limiting triangle block 620's restriction on the ratchet 609's rotation. Since the width of the second connecting shaft 608 is greater than that of the ratchet 609, the limiting triangle block 620 can be completely positioned in front of the ratchet 609, facilitating the reset of the hollow gear 602 and the drive gear 606. The drive gear 606 has fewer teeth than the hollow gear 602. This allows the user to slowly drive the hollow gear 602 to rotate on the rotary drive gear 606, thereby accurately recording the maximum elongation of the wool yarn when it is about to break, increasing the functionality of the equipment. The maximum elongation of a typical wool yarn usually does not exceed 1.5 times its own length. The distance between the deflector 708 and the fixed wheel 4 is 10 centimeters, and the rotation circumference of the take-up wheel 2 is greater than 5 centimeters. Therefore, the user does not need to rotate the take-up wheel 2 one full turn to break the wool yarn, increasing the convenience of the equipment.

[0042] Furthermore, the fixing mechanism 7 also includes a first screw 703, a second knob 704, and a first threaded sleeve 705. The first screw 703 is rotatably mounted on the upper side of the extrusion cylinder 702, the second knob 704 is fixedly mounted on the upper side of the first screw 703, and the first threaded sleeve 705 is fixedly mounted on the upper side of the fixing wheel 4. The first threaded sleeve 705 is threadedly connected to the first screw 703. A schematic diagram of this structure is shown below. Figure 7 The lower end of the third movable groove 701 is the center of the fixed wheel 4, so that the wool yarn can also rotate coaxially when the fixed wheel 4 rotates, which is beneficial for the twist test of the wool yarn. The extrusion cylinder 702 is cylindrical and fixes the wool yarn by extrusion. Combined with the fixation of the wool yarn by the clamping mechanism 5 mentioned above, the wool yarn can be fixed at both ends. The center of the fixed wheel 4 is also opposite to the lowest point of the clamping groove 506 opened on the winding wheel 2, so that the wool yarn can be in a horizontal state after it is fixed.

[0043] Furthermore, the fixing mechanism 7 also includes engaging blocks 706, engaging grooves 707, and reversing wheels 708. Engaging blocks 706 are fixedly installed in an array within the third movable groove 701. Engaging grooves 707 are arrayed on the lower side of the extrusion cylinder 702, and the engaging blocks 706 engage within the engaging grooves 707. Reversing wheels 708 are fixedly installed on the front side of the mounting base plate 1, with the position of the reversing wheels 708 opposite to the lower end of the third movable groove 701. A schematic diagram of this structure is shown below. Figure 1 and Figure 7This structure allows the wool yarn to be more stably clamped in the third movable groove 701 through the engagement between the locking block 706 and the locking groove 707, in order to meet the needs of tension testing and twist testing. The two sides of the cross-section of the reversing wheel 708 are arc-shaped, and its overall shape is hourglass-shaped. The lower side of its narrowest position is opposite to the lower end of the third movable groove 701, so that the wool yarn can remain horizontal after being fixed, increasing the stability of the equipment during use.

[0044] Furthermore, the counting drive mechanism 8 also includes a first gear 802, an electronic counter 803, a second gear 804, a lever 805, and a connecting block 806. The first gear 802 is rotatably mounted on the mounting side plate 801. The axis of the first gear 802 is on the same horizontal line as the axis of the fixed wheel 4, and the first gear 802 is fixedly connected to the fixed wheel 4. The first gear 802 is fixedly mounted on the counting shaft of the electronic counter 803. The second gear 804 is rotatably mounted on one side of the mounting side plate 801, meshing with the first gear 802. The lever 805 is fixedly mounted on the second gear 804. The connecting block 806 is fixedly mounted on the mounting side plate 801 and is fixedly mounted on the mounting block 3. A schematic diagram of this structure is shown below. Figure 6 The electronic counter 803 is powered by power supply 13, and its wiring is hidden in mounting block 3 and mounting side plate 801. The electronic counter 803 is equipped with a display screen and a reset button, which are existing technologies. The specific working principle will not be described in detail here. There is a clear gap between the connecting block 806 and the fixed wheel 4, so that the fixed wheel 4 has enough rotation space. The twist of wool yarn varies. The twist of yarn in meters is approximately between 200 and 800 depending on the production mode of different processes. The number of rotations required for this equipment is between 20 and 80. The second gear 804 has more teeth than the first gear 802, so that when the user moves the lever 805, the first gear 802 can rotate quickly, thereby quickly reaching the required number of rotations and increasing the convenience of using the equipment.

Figure 8 and Figure 10 The magnifying lens 903 can magnify the observation of wool yarn and can be moved to make the observation more comprehensive. The function of the thread-pulling needle 910 is to pull the yarn apart during the twist test, making the twist test more convenient.

[0046] Furthermore, a background strip 10 is fixedly installed on the front side of the mounting base plate 1. The background strip 10 is located below the L-shaped plate 901, and a horizontal mark groove 11 is formed on the background strip 10. Arc-shaped finger grooves 12 are formed on the upper and lower sides of the mounting block 3. A schematic diagram of this structure is shown below. Figure 8 and Figure 10 The background strip 10 makes the wool yarn more visible when placed, and the horizontal groove 11 can also be used to judge whether the wool yarn is in a horizontal state by comparing it with the background strip 10, which increases the convenience of using the equipment. The arc-shaped finger groove 12 makes the whole equipment easier and more stable to hold.

[0047] Furthermore, a power supply 13 is fixedly installed inside the mounting block 3, a charging port 14 is provided on the rear side of the mounting block 3, a solar module 15 is fixedly installed inside the mounting block 3, and a solar panel 16 is fixedly installed on the rear side of the mounting block 3. A schematic diagram of this structure is shown below. Figure 9 Since the electronic counter 803 requires less power, the solar module 15 and solar panel 16 can supply power to the power source 13 without charging, which increases the convenience of using the equipment. The surface of the solar panel 16 is covered with a transparent plastic plate to protect the solar panel 16.

[0048] Working principle: When using this invention, take a wool yarn sample longer than 10 cm, insert one end of it into the third movable groove 701, and then rotate the second knob 704. The first screw 703 drives the extrusion cylinder 702 to descend and press the yarn through the thread action between it and the first screw sleeve 705. Pass the other end of the yarn through the gap between the take-up wheel 2 and the deflector wheel 708. Then lift the lifting block 502, so that the first movable block 508 compresses the compression spring 511, and the clamping block 504 separates from the clamping groove 506. Place the yarn in the clamping groove 506 and then release the lifting block 502 so that the clamping block 504 presses the yarn. At this time, the yarn should be in a state parallel to the horizontal gauge groove 11.

[0049] During tension testing, the first knob 607 is rotated, which drives the drive gear 606 to rotate. The drive gear 606 meshes with the hollow gear 602, which in turn drives the hollow gear 602 and the take-up wheel 2 to rotate, thereby winding up the yarn. When the drive gear 606 rotates, the limiting triangle block 620 abuts against the ratchet 609. The unidirectional rotation of the limiting triangle block 620 can limit the reverse rotation of the drive gear 606. When the yarn breaks, the first knob 607 is stopped from being rotated. The elongation of the yarn can be observed by observing the relative position of the length mark groove 603 and the pointing block 604. Then, the hollow button 621 is pressed, which moves the movable block 617 along the mounting cylinder 612 to the second connecting shaft 608, thereby releasing the limiting triangle block 620 from limiting the ratchet 609. Then, the hollow gear 602 is reset under the gravity of the counterweight block 605.

[0050] When performing a twist test, fix the yarn according to the above steps, then move the lever 805. The lever 805 drives the second gear 804 to rotate, thereby driving the fixed wheel 4 and the counting shaft of the electronic counter 803 to rotate through the meshing between the second gear 804 and the first gear 802, thus performing a twist test on the yarn. Pulling out the thread-pulling needle 910 allows the yarn to be pulled, making the twist test easier to perform.
