Description
Technical Field
[0001] The utility model belongs to the technical field of textile sizing, and in particular relates to a yarn synchronous winding device of a sizing machine for continuous performance testing. Background Art
[0002] Sizing is a crucial step in the textile production process. It involves sizing, drying, and winding the warp yarns (longitudinal yarns). Sizing reduces yarn breakage and hairiness during the weaving process, lowering the yarn breakage rate and improving yarn weaving performance. Sizing performance directly impacts the success of the subsequent weaving process and the quality of the fabric. Therefore, after sizing, the yarn is tested for performance.
[0003] Traditional sizing performance tests often use an intermittent operation method, that is, when the sizing machine is working, the sizing-treated yarn is unwound from the weaving shaft and the yarn that meets the performance test length is removed, which is generally 100-200 meters; and in order to prevent the sizing yarn already wound on the weaving shaft from becoming messy due to the unwinding of longer yarns, the industry generally adopts a small amount of multiple removal method, that is, only 1-20 meters of sizing yarn is unwound each time, and then these shorter sizing yarn segments removed multiple times are spliced together to form a whole sizing yarn segment with a length of 100-200 meters. Finally, this whole segment after multiple splicing is placed in the test module for performance testing.
[0004] Although this traditional sizing performance test method can obtain sizing test results, on the one hand, the shorter sizing yarns are connected into a whole through multiple joints before the performance test is carried out. The yarns at the joints will have a great interference with the results of the yarn performance test, affecting the accuracy of the sizing performance test; on the other hand, the steps of removing the sizing yarns in small quantities and then splicing them are relatively cumbersome, which will greatly affect the sizing test efficiency, and cannot achieve continuous and synchronous winding and real-time monitoring of the sized yarns, and cannot timely feedback the performance test data of the sizing yarns and discover and solve possible problems, which ultimately leads to poor consistency in the obtained sizing performance and may even affect the subsequent weaving efficiency. Utility Model Content
[0005] In response to the above technical problems, the utility model provides a synchronous winding device for a sizing machine yarn for continuous performance testing, which abandons the traditional method of winding the sizing yarn onto a weaving shaft and then unwinding it for sampling, and realizes sampling while the sizing yarn is wound onto the weaving shaft. It can obtain continuous yarn that meets the test length requirements at one time, making the test more accurate, and avoids the tedious yarn joint operation caused by the existing method, thereby improving the work efficiency of the performance test and avoiding the problems that may be caused by the unwinding operation.
[0006] To achieve the above-mentioned object, the utility model provides a sizing machine yarn synchronous winding device for continuous performance testing, comprising a synchronous wheel 31 and a programmable logic controller 32 installed at the drag roller 2 in the sizing machine head 1, and a yarn guide hook 33, a stepping motor 42, an active drum 41, a rotating wheel 43, a rotating bearing 44 and a detachable bobbin 45 installed in a sizing winder 40;
[0007] In addition to the traction roller 2, the sizing machine head 1 is also provided with a pressure length measuring roller 3, a tension adjustment roller 4 and a weaving shaft 5. The sizing yarn is guided to the top of the pressure length measuring roller 3 through a telescopic reed (not shown in the figure), and then transmitted to the tension adjustment roller 4 through the traction roller 2, and then wound onto the weaving shaft 5.
[0008] In the synchronous winding device, the synchronous wheel 31 is electrically connected to the programmable logic controller 32. The programmable logic controller 32 controls the speed of the stepping motor 42 to drive the active drum 41 to rotate at the same linear speed as the traction roller 2, thereby making the detachable bobbin 45 also rotate at the same linear speed as the traction roller 2.
[0009] The yarn guide hook 33 guides part of the sizing yarn after passing through the tension adjustment roller 4 to the detachable yarn tube 45; the stepping motor 42 executes the speed instruction of the programmable logic controller 32 and drives the rotating wheel 43 to rotate, and the rotating wheel 43 is connected to the rotating bearing 44 through a belt and drives it to rotate. The rotating bearing 44 drives the active rotating drum 41 on its outer ring to rotate, and the active rotating drum 41 finally drives the detachable yarn tube 45 to rotate.
[0010] In the synchronous winding equipment, the synchronous wheel 31 is provided with an encoder for obtaining the real-time rotational linear speed of the traction roller 2 and transmitting it to the programmable logic controller 32. The programmable logic controller 32 will control the rotation speed of the stepper motor 42 according to the real-time rotational linear speed of the traction roller 2; the pressure-applying length measuring roller 3 is used to pressurize the sizing yarn and test the sizing yarn length. The tested sizing yarn length data will be collected in real time and displayed on the programmable logic controller 32; the tension adjustment roller 4 is used to adjust the winding tension at the sizing yarn weaving shaft.
[0011] In one embodiment, the rotational linear speed of each component satisfies the following relationship:
[0012] V1=V2=V3
[0013] V4=V5=3 / 5V1
[0014] V3=V6
[0015] Among them, V1 is the rotational linear speed of the traction roller 2, V2 is the rotational linear speed of the synchronous wheel 31, V3 is the rotational linear speed of the active drum 41; V4 is the rotational linear speed of the rotating bearing 44, V5 is the rotational linear speed of the rotating wheel 43, and V6 is the rotational linear speed of the detachable yarn tube 45.
[0016] In one embodiment, the rotational angular velocity of each component satisfies the following relationship:
[0017] n5=3 / 200πV1
[0018] n1 / n5=2 / 3
[0019] n4=n3
[0020] Among them, V1 is the rotational linear velocity of the traction roller 2, n1 is the angular velocity of the synchronous wheel 31, n3 is the angular velocity of the active drum 41, n4 is the angular velocity of the rotating bearing 44, and n5 is the angular velocity of the rotating wheel 43.
[0021] In one embodiment, the linear velocity V1 of the traction roller 2 and the linear velocity V2 of the synchronous wheel can be collected in real time through the synchronous wheel 31. The linear velocity V1 of the traction roller 2 is equal to the linear velocity V2 of the synchronous wheel 31. At the same time, the diameter of the synchronous wheel is known to be d1, and the angular velocity of the synchronous wheel 31 can be obtained as n1; the linear velocity of the active drum 41 driven by the rotating bearing 44 is V3, and its diameter is d3. Here, V3=V2=V1, so the angular velocity of the active drum is obtained as n3; the rotating bearing 44 is connected to the rotating wheel 43 by a belt. 4's angular velocity n4 is equal to n3. According to the diameter of the rotating bearing 44 being d4, it can be concluded that the linear velocity V4 of the rotating bearing 44 is 3 / 5V1. The linear velocity V5 of the runner 43 driven by the stepper motor is equal to the linear velocity of the rotating bearing 44. Its diameter is d5. It can be concluded that the angular velocity n5 of the runner 43 is 3 / 200πV1, and thus n1 / n5=2 / 3 is obtained. The PLC can set the rotation speed of the stepper motor 42 according to this ratio, and finally make the rotation speed of the detachable bobbin 45 the same as that of the dragging roller 2, thereby realizing synchronous winding.
[0022] In one embodiment, the programmable logic controller 32 is provided with a display screen.
[0023] In one embodiment, the yarn guide hook 33 is fixed on one side of the sizing winder 40 near the tension adjustment roller 4 and is connected to the main frame of the sizing winder 40 through a support plate.
[0024] In one embodiment, the yarn guide hook 33 can be made of ceramic material, high-hardness chrome-plated metal material, stainless steel material, plastic material, manganese steel material, or aluminum alloy material.
[0025] In one implementation, the yarn guide hook 33 can be replaced by an alumina ceramic eyelet, that is, a portion of the sizing yarn after passing through the tension adjustment roller 4 is led out by the alumina ceramic eyelet and wound onto the detachable yarn tube 45 .
[0026] Advantages of this utility model:
[0027] The present invention achieves continuous synchronous winding and real-time monitoring of the yarn by making the traction roller 2 and the detachable yarn tube 45 rotate at the same linear speed. The step of connecting the shorter sized yarns into a whole through multiple joints before performing the performance test is omitted, which eliminates the interference of multiple joints on the yarn performance test, makes the test more accurate, and improves the work efficiency of the performance test. The present invention can also monitor the status of the yarn in real time during the sizing process, timely feedback the performance test data of the sizing yarn, and discover and solve possible problems, further improving the quality and consistency of the sizing yarn. In addition, the present invention provides a yarn guide hook 33 to directly and independently separate a portion of the sizing yarn from the tension adjustment roller 4 and guide it to the detachable yarn tube 45, so that the sizing yarn wound on the detachable yarn tube 45 exists independently and clearly. Because the sizing yarn wound on the detachable yarn tube 45 is a single winding, there is no problem of becoming messy due to unwinding, and the unwinding can be achieved quickly and smoothly, maintaining the structural integrity of the yarn. Further, under the condition of simulating actual production conditions, the accuracy of the test is guaranteed, and the testing and production efficiency of the sizing yarn are improved. The utility model discloses a yarn synchronous winding device for a sizing machine for continuous performance testing, which not only promotes the technological progress of the textile industry, but also provides strong support for improving product quality and competitiveness.

[0034] The yarn synchronous winding equipment for continuous performance testing of a sizing machine according to the present application will be described below with reference to Embodiment 1, and a structure diagram thereof is shown in
[0035] In addition to the tow roller 2, the sizing machine head 1 is provided with a pressure measuring roller 3, a tension adjusting roller 4 and a weaving shaft 5. The pressure measuring roller 3 is located above the tow roller 2, and the tension adjusting roller 4 is located on the side close to the sizing bobbin winder 40 in the horizontal direction of the tow roller 2. The sizing is guided to the upper side of the pressure measuring roller 3 through an expansion reed (not shown in the figure), and then transmitted to the tension adjusting roller 4 through the tow roller 2, and then wound on the weaving shaft 5.
[0036] In the equipment of the present embodiment, the synchronous wheel 31 is electrically connected with the programmable logic controller 32. The programmable logic controller 32 drives the active rotary drum 41 and the tow roller 2 to rotate at the same linear speed by controlling the rotating speed of the stepping motor 42, so that the detachable yarn pipe 45 also rotates at the same linear speed as the tow roller 2.
[0037] The present embodiment makes the rotating linear speed of the tow roller 2 and the detachable yarn pipe 45 the same, realizes sampling while the sizing is wound on the weaving shaft, that is, the yarn can be continuously and synchronously wound and monitored in real time, and the step of connecting the shorter sizings through multiple joints to form a whole before performance testing is omitted. This not only eliminates the interference of multiple joints on the performance testing of the yarn, makes the testing accuracy higher, and improves the work efficiency of performance testing, but also can monitor the state of the yarn in real time during the sizing process, timely feedback the performance testing data of the sizing, and find and solve possible problems, further improving the quality and consistency of the sizing.
[0038] In the device of the embodiment, the stepper motor 42 executes the rotating speed instruction of the programmable logic controller 32 and drives the rotating wheel 43 to rotate, the rotating wheel 43 is connected with the rotating bearing 44 through a belt and drives the rotating bearing 44 to rotate, the rotating bearing 44 drives the driving cylinder 41 at the outer ring to rotate, and the driving cylinder 41 finally drives the detachable yarn pipe 45 to rotate.
[0039] In the device of the embodiment, the yarn guide hook 33 guides the part of the sizing yarn after the tension adjusting roller 4 to the detachable yarn pipe 45; this abandons the traditional method of winding the sizing yarn to the weaving shaft and then unwinding and sampling, directly winds the sizing yarn to the detachable yarn pipe 45 independently, makes it exist independently and clearly, realizes quick and smooth unwinding, can obtain the continuous yarn meeting the length requirement of the sizing yarn test at one time, further ensures the accuracy of the sizing yarn performance test such as automatic single yarn strength test and yarn hairiness test under the condition of simulating the actual production condition, improves the sizing yarn test and production efficiency, and maintains the structural integrity of the yarn.
[0040] In the device of the embodiment, the synchronous wheel 31 is provided with an encoder for obtaining the real-time rotating linear speed of the drawing roller 2 and transmitting it to the programmable logic controller 32, the programmable logic controller 32 will control the rotating speed of the stepper motor 42 according to the real-time rotating linear speed of the drawing roller 2; the pressure measuring roller 3 is used for applying pressure to the sizing yarn and testing the length of the sizing yarn, and the testing length data of the sizing yarn is collected and displayed on the programmable logic controller 32 in real time; the tension adjusting roller 4 is used for adjusting the winding tension at the sizing yarn weaving shaft.
[0041] In the device of the embodiment, the detachable yarn pipe 45 can be directly taken down after the sizing yarn winding is completed, which is more convenient for yarn unwinding and the next sizing yarn performance test; meanwhile, when the yarn pipe is worn or scrapped after being used for a long time, it can also be conveniently replaced.
[0042] In the device of the embodiment, the rotating linear speeds of the components satisfy the following relationship:
[0043] V1=V2=V3
[0044] V4=V5=3 / 5V1
[0045] Wherein, V1 is the rotating linear speed of the drawing roller 2, V2 is the rotating linear speed of the synchronous wheel 31, V3 is the rotating linear speed of the driving cylinder 41; V4 is the rotating linear speed of the rotating bearing 44, and V5 is the rotating linear speed of the rotating wheel 43.
[0046] In the device of the embodiment, the rotating angular speeds of the components satisfy the following relationship:
[0047] n5=3 / 200πV1
[0048] n1 / n5=2 / 3
[0049] n4=n3
[0050] Among them, V1 is the rotational linear velocity of the traction roller 2, n1 is the angular velocity of the synchronous wheel 31, n3 is the angular velocity of the active drum 41, n4 is the angular velocity of the rotating bearing 44, and n5 is the angular velocity of the rotating wheel 43.
[0051] In the device of this embodiment, the rotational linear velocity V1 of the traction roller 2 and the rotational linear velocity V2 of the synchronization wheel 31 can be collected in real time. The rotational linear velocity V1 of the traction roller 2 is equal to the rotational linear velocity V2 of the synchronization wheel 31. At the same time, the diameter of the synchronization wheel is known to be d1, and the angular velocity of the synchronization wheel 31 can be obtained to be n1.
[0052] The linear velocity of the active drum 41 driven by the rotating bearing 44 is V3. Its diameter is d3. Here, V3 = V2 = V1, resulting in an angular velocity of the active drum n3. The angular velocity n4 of the rotating bearing 44, which is connected to the pulley 43 via a belt, is equal to n3. Based on the diameter d4 of the rotating bearing 44, the linear velocity of the rotating bearing 44 is V4 = 3 / 5 V1.
[0053] The linear velocity V5 of the rotating wheel 43 driven by the stepper motor is equal to the linear velocity of the rotating bearing 44. Its diameter is d5. The angular velocity n5 of the rotating wheel 43 can be obtained as n5 = 3 / 200πV1, and thus n1 / n5 = 2 / 3. The programmable logic controller 32 can set the speed of the stepper motor 42 according to this ratio, and ultimately make the rotation linear velocity of the detachable bobbin 45 and the traction roller 2 the same, thereby achieving synchronous winding;
[0054] At the same time, according to actual conditions, the rotational angular velocity ratio n1 / n5 can be increased or decreased so that the detachable bobbin 45 can tighten or loosen the wound sizing yarn to facilitate winding or unwinding.
[0055] Therefore, in one implementation, the rotational angular velocity ratio of n1 / n5 can be flexibly adjusted according to the actual operating state. By modifying this ratio, a new embodiment can be formed, which is also within the scope of protection of the present utility model.
[0056] In the device of this embodiment, the front structure of the winding part of the yarn synchronous winding device of the sizing machine for continuous performance testing of the utility model embodiment is as follows: Figure 2 As shown; wherein, the yarn guide hook 33 is fixed on one side of the sizing yarn winder 40 above the sizing yarn winder near the tension adjustment roller 4, and is connected to the main frame of the sizing yarn winder 40 through a support plate (not shown in the figure); the yarn guide hook 33 guides out multiple sizing yarns and winds them onto the detachable yarn tube 45 in a single winding manner; the detachable yarn tube 45 is driven to rotate by the active rotating drum 41.
[0057] In the device of this embodiment, the yarn guide hook 33 can be made of ceramic material, high-hardness chrome-plated metal material, stainless steel material, plastic material, manganese steel material, or aluminum alloy material.
[0058] In the device of this embodiment, the yarn guide hook 33 can control the number of wound yarns by increasing or decreasing the number of yarns and the arrangement density of the yarns; the number of yarn guide hooks 33 can be adjusted according to the axial length of the weaving shaft, the warp arrangement density and the width of the yarn guide hook 33.
[0059] In one embodiment, the yarn guide hook 33 can be replaced by an alumina ceramic eyelet. That is, a portion of the sizing yarn after passing through the tension adjustment roller 4 is guided by the alumina ceramic eyelet and wound onto the detachable bobbin 45. The remaining components and working method are the same as those of the present embodiment. New embodiments can be formed based on this, and they are also within the scope of protection of the present utility model.
[0060] The working principle of the present invention is as follows: the sizing yarn after sizing and drying is guided to the top of the pressurized length measuring roller 3 through the telescopic reed (not shown in the figure), and then transmitted to the tension adjustment roller 4 through the dragging roller 2. Most of the sizing yarn after passing the tension adjustment roller 4 is wound onto the weaving shaft 5. At the same time, the remaining small part of the sizing yarn is separated out through the yarn guide hook 33 and wound onto the detachable yarn tube 45.
[0061] In this process, the rotation of the pressurized length measuring roller 3 and the tension adjusting roller 4 is driven by the dragging roller 2, and the rotation linear speed of the dragging roller 2 is collected by the synchronous wheel 31 and transmitted to the programmable logic controller 32. The programmable logic controller 32 then directly adjusts the rotation speed of the stepper motor 42 in the yarn winding machine 40. The rotation of the stepper motor 42 drives the rotating wheel 43 to rotate, and the rotating wheel 43 is connected to the rotating bearing 44 through a belt and drives it to rotate. The rotating bearing 44 drives the active rotating drum 41 to rotate, and the active rotating drum 41 drives the detachable yarn tube 45 to rotate, so that the rotation linear speeds of the dragging roller 2 and the detachable yarn tube 45 are finally made the same.
[0062] Since the rotational linear speeds of the dragging roller 2 and the detachable yarn tube 45 are the same, when the yarn guide hook 33 guides multiple sized yarns to be wound onto the detachable yarn tube 45, continuous synchronous winding and real-time monitoring of the yarn can be achieved; in addition, the yarn guide hook 33 can adjust the number of wound sized yarns according to actual conditions, so that the sized yarns wound onto the detachable yarn tube 45 exist independently and are clearly distinguished, and finally achieve fast and smooth unwinding, which is convenient for the next step of sizing performance testing.
[0063] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Anyone familiar with this technology may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
