Description

Technical Field

[0001] This utility model relates to the field of testing technology, specifically to a testing instrument for testing the smoothness of industrial silk. Background Technology

[0002] Industrial yarns (polyester industrial yarn, nylon industrial yarn, etc.) are widely used in the automotive industry, construction engineering, marine and energy engineering, and other fields. The silkiness of industrial yarns is an important indicator for evaluating their performance. For example, in mechanical rubber products (such as automotive airbags and cables), industrial yarns must possess high toughness and impact resistance; the "silky smoothness" of industrial yarns is reflected in low friction and smoothness during operation. Therefore, silkiness testing of industrial yarns is necessary.

[0003] In existing technologies, when using silk smoothness testing instruments, the tension of the silk thread cannot be flexibly adjusted and monitored, which easily leads to a decrease in testing accuracy due to loosening. Therefore, it is necessary to develop a testing instrument that can adjust and monitor the tension of the silk thread to meet the testing needs of industrial silk smoothness. Utility Model Content

[0004] The purpose of this invention is to provide a testing instrument for testing the smoothness of industrial silk, so as to solve the problem that existing testing instruments in the background art cannot flexibly adjust and monitor the tension of the silk when conducting tests, which leads to a decrease in accuracy due to loosening during testing.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An instrument for testing the smoothness of industrial silk includes a limiting frame. An adjusting tension component is disposed on the inner side of the limiting frame to adjust the tension of the silk. Stabilizing limiting components are disposed on the front sides of both ends of the limiting frame to maintain rotational stability. The adjusting tension component includes an adjusting screw, and a limiting slider is disposed on the outer side of the adjusting screw. A movable plate is mounted on the front side of the limiting slider, and slotted photoelectric sensors are disposed at both ends of the movable plate. A fixed plate is mounted on the side of the slotted photoelectric sensor away from the limiting slider, and a pressure plate is movably embedded in the inner side of the fixed plate. Force-sensing guide wheel; the stabilizing and limiting component includes a limiting plate, and a drive shaft is movably arranged in the middle of the limiting plate. The end of the drive shaft is a square structure with a screw hole. A splicing sleeve is provided on the front of the limiting plate, and the splicing sleeve is located outside the drive shaft. A square inclined groove is opened between the drive shaft and the splicing sleeve, and a square inclined frame is spliced ​​on the inner side of the square inclined groove. A spring frame is installed on the outer side of the square inclined frame, and a compression frame is provided on the inner side of the back of the spring frame. The compression frame contacts the front of the splicing sleeve. A fastening screw is provided in the middle of the square inclined frame, and the fastening screw is located inside the screw groove.

[0007] Preferably, the front of the limiting frame is provided with three sets of limiting grooves, and the limiting grooves are located on the outside of the limiting slider and the groove-shaped photoelectric sensor, respectively.

[0008] Preferably, a take-up reel is installed on the outer side of the splicing sleeve, and a ball bearing is embedded on the back of the splicing sleeve, the ball bearing contacting the limiting disc.

[0009] Preferably, the input end of the drive shaft is provided with a drive motor, and the drive motor is fixed to the back of the limiting plate by a bolt structure. A combined bearing is provided on the outer side of the drive shaft near the drive motor, and the combined bearing is located on the inner side of the limiting plate.

[0010] Preferably, a fastening knob is installed at the end of the fastening screw away from the drive shaft, and the outer side of the fastening screw near the fastening knob is fixed to the square inclined frame by a bearing. A strong spring is provided on the inner side of the spring frame and the compression frame.

[0011] Preferably, the top of the adjusting screw is provided with an adjusting knob, and both ends of the adjusting screw are fixed to the inside of the limiting frame by bearings.

[0012] Preferably, the grooved photoelectric sensor has limit sliding columns installed on both sides of its back side, and the limit sliding columns are located inside the limit sliding groove. The two sides inside the limit sliding groove are provided with sliding column grooves and limit sliding column combinations. The grooved photoelectric sensor and the pressure sensing guide wheel are provided with connecting wires on their back sides.

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial effects:

[0014] This utility model features an adjustable tensioning component. By using an adjusting screw to rotate and drive the limiting slider to adjust its height along the inner side of the limiting groove, the industrial wire at the bottom of the pressure sensing guide wheel groove will achieve a tensioning effect during the adjustment process. At the same time, the pressure sensing guide wheel will constantly detect the pressure on the guide wheel to determine the tension status and prevent breakage.

[0015] Industrial yarn needs to be placed on a take-up reel. During testing, the take-up reel needs to be placed on the surface of the testing structure. This invention prevents loosening during rotation due to gaps in the splicing process by setting a stabilizing limiting component. Specifically, this invention uses a square drive shaft and a splicing sleeve with a square inclined groove on the inner side. The combined square inclined frame splicing and pressing increases the tightness. When the inclined surfaces are in contact, continuous pressing supports the outer splicing sleeve. Continuous pressing keeps the splicing sleeve and drive shaft in a pressed and locked state. Then, the spring frame and pressing frame, together with the internal strong spring, press the take-up reel onto the limiting plate, thereby preventing it from falling off and shaking. The stabilizing limiting component effectively increases stability and prevents movement from affecting the accuracy of the test. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5The present invention discloses a tester for testing the smoothness of industrial silk threads, comprising a limiting frame 1, an adjusting tension component disposed on the inner side of the limiting frame 1 for adjusting the tension of the silk thread, and stabilizing limiting components disposed on the front of both ends of the limiting frame 1 for maintaining rotational stability; the adjusting tension component includes an adjusting screw 4, and a limiting slider 402 disposed on the outer side of the adjusting screw 4, a movable plate 401 mounted on the front of the limiting slider 402, and slotted photoelectric sensors 501 disposed at both ends of the movable plate 401, a fixed plate mounted on the side of the slotted photoelectric sensor 501 away from the limiting slider 402, and a pressure sensing guide wheel 5 movably embedded in the inner side of the fixed plate; the stabilizing limiting component... The device includes a limiting plate 102, and a drive shaft 203 is movably disposed in the middle of the limiting plate 102. The end of the drive shaft 203 is a square structure with a screw hole. A splicing sleeve 204 is disposed on the front of the limiting plate 102, and the splicing sleeve 204 is located outside the drive shaft 203.

[0024] With the above technical solution, by installing the tension adjustment component, the adjusting screw 4 can be rotated to drive the limit slider 402 to adjust the height along the inner side of the limit groove 101. During the adjustment process, the industrial wire set at the bottom of the groove of the pressure sensing guide wheel 5 will achieve the tensioning effect.

The fastening screw 302 needs to be subjected to a certain rotational force to rotate, and it will not loosen or fall off under normal conditions.

[0034] Specifically, the top of the adjusting screw 4 is provided with an adjusting knob 403, and both ends of the adjusting screw 4 are fixed to the inside of the limiting frame 1 by bearings.

[0035] Through the above technical solution, the adjustment knob 403 can provide a grip for the user to easily control the rotation of the adjustment screw 4, and the adjustment screw 4 can be used to limit the limit slider 402.

[0036] Specifically, the slotted photoelectric sensor 501 has limit sliding posts 502 installed on both sides of its back side, and the limit sliding posts 502 are located inside the limit sliding groove 101.
