Description

Technical Field

[0001] The present invention relates to the technical field of yarn strength detection, and more specifically, to a yarn strength detection device for spinning. Background Art

[0002] The yarn strength test for spinning mainly tests the tensile strength of the yarn. During the spinning process, the yarn will be displaced by the traction of the traction machine, which will produce tension on the yarn. When the tensile strength of the yarn is insufficient, it is easy to break, which will lead to the problem of missing needles in spinning. After the yarn production is completed, the tensile strength of the yarn is usually tested.

[0003] Existing yarn strength detection devices usually use a tensile gauge to stretch the yarn. However, during the detection process, the existing detection device requires the inspector to observe the change in the tensile value of the tensile gauge in real time. At the moment the yarn breaks, the tensile gauge will automatically reset, resulting in the inspector being unable to fully determine the maximum tensile value of the yarn. At the same time, the existing yarn detection method can only detect the maximum tensile strength of the yarn, but cannot detect the maximum tensile force that the yarn can withstand instantaneously. During the spinning process of the yarn, the traction force of the traction machine is constantly changing, which will result in an instantaneous strong tensile state. Therefore, the instantaneous maximum tensile strength of the yarn needs to be detected. For this reason, the existing detection device needs to be structurally optimized. Summary of the invention

[0044] like Figure 1 , Figure 4 As shown, a yarn strength detection device for spinning includes a detection platform 1, a tension gauge mechanism is arranged on one side of the top of the detection platform 1, the tension gauge mechanism includes a detection installation box 16, a first clamping unit 14 is arranged in the middle of the detection installation box 16, a pointer 15 is arranged at one end of the front of the first clamping unit 14, and scale lines 13 are arranged at positions of the detection installation box 16 near both sides of the pointer 15;

[0045] The dynamometer mechanism also includes side boxes 18 arranged on both sides of the detection installation box 16, and a positioning and locking mechanism is arranged inside the side boxes 18. The positioning and locking mechanism includes a limit plate 39 arranged inside the side box 18, and a limit tooth groove 40 is arranged on one side of the limit plate 39 close to the detection installation box 16. A support plate 45 that slides up and down inside the detection installation box 16 is arranged on the top of the first clamping unit 14, and limit teeth 41 that are mutually engaged with the limit tooth groove 40 are arranged at both ends of the support plate 45. A control mechanism that is mutually adapted to the positioning and locking mechanism is arranged on the top of the detection installation box 16;

[0046] like Figure 1 , Figure 2 As shown, a supporting platform mechanism is provided in the middle of the top of the detection platform 1, and the supporting platform mechanism includes a supporting platform 10, and a wire tower 11 is supported on the top of the supporting platform 10, and a yarn 5 is wound around the outer side of the wire tower 11, and one end of the yarn 5 is inserted from the bottom of the tensile gauge mechanism and is positioned and clamped by a first clamping unit 14;

[0047] The support platform mechanism also includes a support rail 9 symmetrically arranged in the middle of the top of the detection platform 1, and a support slider 25 is arranged on the top of each of the support rails 9. The tops of the two groups of support sliders 25 are away from the detection installation box 16 and jointly support the support platform 10. The tops of the two groups of support sliders 25 are close to the detection installation box 16 and jointly support the clamping plate 12.

As the first clamping unit 14 continues to move downward, when the yarn 5 reaches the maximum tensile force and breaks, the two ends of the support plate 45 are engaged with the limit teeth 41 and the limit tooth grooves 40 and cannot be reset, thereby maintaining the corresponding stability of the positions of the pointer 15 and the scale line 13, which is convenient for the detection personnel to read. After the reading is completed, the control mechanism is pressed to release the engagement of the limit tooth grooves 40 and the limit teeth 41, so that the overall structure of the support plate 45 is reset.

[0052] The dynamometer mechanism also includes side boxes 18 arranged on both sides of the detection installation box 16, and a positioning and locking mechanism is arranged inside the side boxes 18.

The detection platform 1 is provided with piston chambers 20 that are interconnected with the collecting chamber 4 at positions on both sides of the collecting chamber 4, and a plurality of groups of first springs 22 are evenly provided at the bottom of the piston chamber 20, and the tops of the first springs 22 jointly support a piston plate 21, and the edge of the piston plate 21 is in contact with the inner wall of the piston chamber 20, and the top of the piston plate 21 is provided with an upper pressing plate 3 extending to the top of the detection platform 1, and a first guide wedge 23 is provided at one end of the upper pressing plate 3 close to the detection installation box 16;

[0061] like Figures 7 to 10 As shown, both ends of the bottom of the traction plate 2 are provided with rolling mechanisms adapted to the upper pressure plate 3, and the rolling mechanisms include support slide bars 32 symmetrically arranged at both ends of the bottom of the traction plate 2, and the outer sliding sleeve of the support slide bar 32 is provided with a displacement slider 26, and the outer sides of the support slide bar 32 are provided with support springs 31 on both sides of the displacement slider 26, and the bottom of the displacement slider 26 is provided with an extrusion wheel 24 that rolls and displaces on the top of the upper pressure plate 3 and the first guide wedge block 23, and the clamping plate 12 is symmetrically provided with a second guide wedge block 30 at a position close to the displacement slider 26, and one end of the displacement slider 26 close to the second guide wedge block 30 is guided and squeezed by the second guide wedge block 30;

[0062] Two groups of first limiting slide bars 27 penetrating the traction plate 2 are symmetrically arranged on one side of the clamping plate 12 close to the traction plate 2. The first limiting slide bars 27 are located between the traction plate 2 and the clamping plate 12 and are sleeved with first return springs 29 on the outer sides. A second clamping unit 28 is arranged in the middle of the clamping plate 12. The clamping plate 12 and the top of the support platform 10 are both fastened to the support slider 25.

[0063] The spinning yarn strength detection device proposed in this embodiment has the same basic structure as that of Embodiment 2, and the difference or improvement is that: when the maximum tensile strength of the yarn 5 needs to be detected, one end of the yarn 5 wound on the outside of the pylon 11 is passed through the clamping plate 12, the traction plate 2, the first steering wheel 19, and the second steering wheel 46 in sequence, and then one end of the yarn 5 is clamped by the first clamping unit 14, and the yarn 5 is clamped synchronously by the second clamping unit 28 in the middle of the clamping plate 12, so that the yarn 5 is in a straightened state;

[0064] At this time, the support plate 45 is in the initial position of the top of the detection installation box 16 as a whole, and the support platform 10 on the top of the support slider 25 is also in the initial position close to one end of the detection installation box 16, and then the drive motor 6 is started to drive the winding shaft 7 to rotate the winding traction rope 8, and the traction plate 2 is pulled by the traction rope 8 to follow the displacement, and then the traction plate 2 squeezes the first return spring 29 to generate a driving force on the clamping plate 12. At this time, the drive motor 6 drives the winding shaft 7 to rotate in a slow-speed state, and then drives the traction plate 2 to squeeze the clamping plate 12 and move synchronously at a slow speed;

[0065] As the traction plate 2 squeezes the clamping plate 12, the clamping plate 12 as a whole is pushed, and the support slider 25 is driven by the clamping plate 12 to slide and displace on the top of the support guide rail 9. At this time, the displacement slider 26 moves synchronously with the traction plate 2. The second guide wedge block 30 guides the displacement slider 26, so that the displacement slider 26 drives the extrusion wheel 24 to roll and displace from the top of the first guide wedge block 23 to the top of the upper pressure plate 3. The extrusion wheel 24 squeezes the upper pressure plate 3 downward, so that the upper pressure plate 3 drives the piston plate 21 to move downward. Since the upper pressure plate 3 is slowly subjected to the extrusion force, the piston plate 21 moves downward synchronously slowly, and the airflow inside the piston chamber 20 is squeezed to be discharged slowly to the inside of the collecting chamber 4.

[0066] As the yarn 5 follows the overall displacement of the traction plate 2, the first clamping unit 14 is pulled to follow the downward displacement, driving the support plate 45 and the pointer 15 to move downward, and stretching the third spring 35. Through the downward displacement of the support plate 45, the limiting tooth 41 is driven to continuously move downward and engage with the limiting tooth groove 40;

[0067] As the third spring 35 is continuously stretched, the rebound force generated is continuously increased to react on the yarn 5, so that the tension on the yarn 5 is continuously increased. When the yarn 5 reaches the maximum tension, the yarn 5 will be broken. At this moment, due to the engagement of the limiting tooth groove 40 and the limiting tooth 41, the support plate 45 will not be reset, so that the pointer 15 can correspond to the scale line 13, which is convenient for the inspection personnel to read.

[0068] At the moment when the yarn 5 breaks, the clamping plate 12 as a whole is not affected by the reverse pulling force of the yarn 5, and then under the action of the rebound force of the first return spring 29, the clamping plate 12 and the traction plate 2 are pushed away from each other, so that the second guide wedge 30 no longer guides the extrusion wheel 24, and under the action of the rebound force of the support slide bar 32, the extrusion wheel 24 is driven to separate from the top of the upper pressure plate 3, and the piston plate 21 is affected by the rebound force of the first spring 22, and instantly moves upward, thereby generating a suction effect on the bottom of the piston chamber 20, and the airflow flows through the top of the collecting chamber 4 to the inside of the piston chamber 20, and then with the flow of airflow, the debris generated at the moment of the yarn 5 breaking is collected into the inside of the collecting chamber 4;

[0069] After the reading of the detection strength is read through the pointer 15 and the scale line 13, the pressing column 17 is pressed to drive the cam frame 34 to squeeze the third guide wedge block 36 to move, and the displacement of the third guide wedge block 36 drives the limiting plate 39 to deflect as a whole, so that the engagement state of the limiting tooth 41 and the limiting tooth groove 40 is released, and under the action of the rebound force of the third spring 35, the support plate 45 is driven to reset as a whole.

[0070] When it is necessary to test the set instantaneous tensile strength of the yarn 5, the support plate 45 is manually pulled downward to move the pointer 15 to the set scale line 13. At this time, the limit tooth 41 and the limit tooth groove 40 are engaged with each other to clamp one end of the yarn 5 with the first clamping unit 14. At the same time, the support platform 10 is displaced as a whole to the initial position close to one end of the detection installation box 16, so that the yarn 5 is in a straightened state;

[0071] Then, the pressing column 17 is pressed, driving the cam frame 34 to move and squeeze the third guide wedge 36, instantly releasing the limiting state of the limiting tooth groove 40 on the limiting tooth 41, and under the action of the rebound force of the third spring 35, driving the support plate 45 to instantly move in the reverse direction, generating an instantaneous pulling force on the yarn 5;

[0072] When the yarn 5 is not broken, the yarn 5 reaches the set instantaneous tensile strength requirement. When the yarn 5 is broken, the yarn 5 is unqualified, thereby realizing the dual detection function of the tensile strength of the yarn 5.

[0073] The specific implementation methods of this embodiment are described above, but this embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms inspired by this embodiment, all of which are within the protection of this embodiment.
