An on-line detection mechanism with tension control

Abstract

This utility model discloses an online detection mechanism with tension control. It relates to the technical field of detection mechanisms and includes a base plate. A motor is connected to the middle of the right side of the base plate. One end of a threaded rod is connected to the drive end of the motor, and the other end of the threaded rod is rotatably connected to a fixed rod. The advantages of this utility model are: by activating an electric push rod, the upper clamping seat moves downward until it contacts the lower clamping seat, clamping and limiting the non-woven fabric roll and the extended non-woven fabric on the lower clamping seat. A bolt drives a pressure plate to press down, fixing the other end of the extended non-woven fabric, facilitating tension detection. When detecting non-woven fibers, only the two ends of the non-woven fiber need to be wound around winding post one and winding post two respectively. Due to the elastic element, winding post one and winding post two will not interfere with the detection of the non-woven fabric, achieving a simultaneous detection effect for both non-woven fabric and non-woven fibers.

Description

Technical Field

[0001] This utility model relates to the field of testing mechanism technology, specifically to an online testing mechanism with tension control. Background Technology

[0002] Nonwoven fabric is a type of non-woven material. It is made by directly forming fibers from polymer chips, short fibers, or filaments into a web through airflow or mechanical means, then reinforcing it through hydroentangling, needle punching, or hot rolling, and finally finishing it to form a non-woven fabric. It is a new type of fiber product with softness, breathability, and planar structure. Its advantages include no fiber lint, strength, durability, silky softness, and it is also a type of reinforcing material. It also has a cotton-like feel. Compared with cotton fabrics, nonwoven bags are easier to shape and cheaper to manufacture.

[0003] In the production and processing of existing nonwoven fabrics, the tension of both the woven fabric and the spun yarn needs to be tested. However, existing testing institutions cannot test the woven fabric and the spun yarn at the same time, resulting in low testing efficiency. Therefore, we propose an online testing institution with tension control. Summary of the Invention

[0004] The purpose of this invention is to provide an online detection mechanism with tension control.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an online testing mechanism with tension control, comprising a base plate, a motor connected to the middle of the right side of the base plate, a threaded rod connected to the drive end of the motor, a fixed rod rotatably connected to the other end of the threaded rod, the fixed rod located at the middle of the left side of the base plate, a movable seat connected to the outer side of the threaded rod, a crossbeam connected to the top of the movable seat, movable frames connected to the front and rear sides of the top of the crossbeam, a tensile testing machine connected to the top side of the movable frame, and a tensile testing machine connected to the left end of the tensile testing machine. A clamping frame is attached, with a bolt threaded to the top center of the clamping frame. A pressure plate is connected to the bottom end of the bolt. Brackets are connected to the front and rear sides of the top of the fixing rod. An electric push rod is connected to the bottom side of the brackets. An upper clamping seat is connected to the drive end of the electric push rod. A lower clamping seat is provided below the upper clamping seat. The lower clamping seat is connected to the outer wall of the fixing rod. Multiple winding columns 1 are slidably connected to the top right side of the lower clamping seat. A second winding column 2 is slidably connected to the inside left side of the clamping frame. Elastic elements are connected to the bottom of the second winding column 2 and the multiple winding columns 1.

[0006] As a further embodiment of this utility model: both of the inner bottom sides of the movable frames are slidably connected with inserts, the outer sides of the inserts are connected with movable rings, the right side of the movable rings is connected with one end of a spring, and the other end of the spring is connected to the inner wall of the movable frame.

[0007] As a further embodiment of this utility model: a plurality of positioning holes are provided on the outer right side of the crossbeam, and the positioning holes and the movable frame are correspondingly arranged.

[0008] As a further embodiment of this utility model: a sliding groove adapted to the moving ring is provided at the middle of the right side of the interior of each of the two movable frames.

[0009] As a further embodiment of this utility model: the upper clamping seat and the lower clamping seat are both provided with recesses on the side that are close to each other, and the upper clamping seat and the lower clamping seat on the same side are provided correspondingly.

[0010] As a further embodiment of this utility model: the pressure plate is located inside the clamping frame, and the pressure plate is square in shape.

[0011] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0012] 1. This utility model uses an electric push rod to move the upper clamping seat downward until it contacts the lower clamping seat, clamping and limiting the non-woven fabric roll and the extended non-woven fabric on the lower clamping seat. The pressure plate is pressed down by bolts to fix the other end of the extended non-woven fabric, which facilitates tension detection. When detecting non-woven fibers, it is only necessary to wrap the two ends of the non-woven fibers around the first and second winding posts respectively. Due to the setting of the elastic element, the first and second winding posts will not interfere with the detection of non-woven fabric, achieving the effect of simultaneously adapting to the detection of non-woven fabric and non-woven fibers.

[0013] 2. This utility model, by moving the insert post outward, causes the moving ring to compress the spring, and simultaneously the end of the insert post disengages from the positioning hole. This allows for changing the position of the tensile testing machine, facilitating tension testing at different locations on the non-woven fabric, improving testing quality. Furthermore, by using two tensile testing machines, two tests can be performed simultaneously, or comparative tests can be conducted, enhancing the practicality of the device.

[0014] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0022] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Please see the appendix Figure 1 -Appendix Figure 5 This utility model discloses an online testing mechanism with tension control, comprising a base plate 1. A motor 3 is connected to the middle of the right side of the interior of the base plate 1. One end of a threaded rod 2 is connected to the drive end of the motor 3. A fixed rod 11 is rotatably connected to the other end of the threaded rod 2. The fixed rod 11 is located in the middle of the left side of the interior of the base plate 1. A movable seat 4 is connected to the outside of the threaded rod 2. A crossbeam 5 is connected to the top of the movable seat 4. Movable frames 6 are connected to the front and rear sides of the top of the crossbeam 5. A tensile testing machine 7 is connected to the top of the movable frame 6. A clamping frame 8 is connected to the left end of the tensile testing machine 7. The clamping frame 8 is located in the middle of the top of its... A bolt 9 is threadedly connected to the fixed rod 11. A pressure plate 10 is connected to the bottom end of the bolt 9. A bracket 12 is connected to the top front and rear sides of the fixed rod 11. An electric push rod 13 is connected to the bottom side of the bracket 12. An upper clamping seat 14 is connected to the drive end of the electric push rod 13. A lower clamping seat 15 is provided below the upper clamping seat 14. The lower clamping seat 15 is connected to the outer wall of the fixed rod 11. Multiple winding columns 16 are slidably connected to the top right side of the lower clamping seat 15. A winding column 2 17 is slidably connected to the inside left side of the clamping frame 8. An elastic element 18 is connected to the bottom of the winding column 2 17 and the multiple winding columns 16.

[0024] In embodiment 1, the inner bottom sides of the two movable frames 6 are slidably connected with insert posts 19, the outer side of the insert posts 19 is connected with a movable ring 20, the right side of the movable ring 20 is connected with one end of a spring 21, the other end of the spring 21 is connected to the inner wall of the movable frame 6, the right outer wall of the crossbeam 5 is provided with multiple positioning holes 22, the positioning holes 22 and the movable frame 6 are correspondingly set, and the middle of the right side of the two movable frames 6 is provided with a sliding groove that matches the movable ring 20.

[0025] Specifically, by moving the insert post 19 outward, the moving ring 20 compresses the spring 21, and at the same time, the end of the insert post 19 disengages from the positioning hole 22. At this time, the position of the tensile testing machine 7 can be changed, which facilitates tension testing at different positions of the nonwoven fabric and improves the testing quality.

[0026] In embodiment 2, the upper clamping seat 14 and the lower clamping seat 15 are both provided with recesses on the side that are close to each other. The upper clamping seat 14 and the lower clamping seat 15 on the same side are correspondingly arranged. The pressure plate 10 is located inside the clamping frame 8 and is square in shape.

[0027] Specifically, the recessed part can limit the non-woven fabric roll and prevent it from slipping during the test. The square shape of the pressure plate 10 allows the bolt 9 to rotate and descend while driving the pressure plate 10 to descend, thereby fixing the other end of the non-woven fabric.

[0028] Working principle:

[0029] When measuring nonwoven fabric, the nonwoven fabric roll is first placed in the recess of the lower clamping seat 15. Then, the electric push rod 13 is activated to move the upper clamping seat 14 downward until it contacts the lower clamping seat 15, clamping and limiting the nonwoven fabric roll and the extended nonwoven fabric on the lower clamping seat 15. The pressure plate 10 is then pressed down by the bolt 9 to fix the other end of the extended nonwoven fabric. During this process, the first winding column 16 and the second winding column 17 move into the interior of the lower clamping seat 15 and the clamping frame 8 respectively through the elastic element 18, so they will not affect the testing of the nonwoven fabric. After fixing, the starting motor 3 drives the threaded rod 2 to rotate, so that the moving seat 4 and the tensile testing machine 7 on the crossbeam 5 move synchronously, increasing the distance between them and the nonwoven fabric roll. The tension test result is obtained through the tensile testing machine 7. When it is necessary to test the tension at different positions of the nonwoven fabric, the insert post 19 is moved outward, so that the moving ring 20 squeezes the spring 21. At the same time, the end of the insert post 19 disengages from the positioning hole 22. At this time, the position of the tensile testing machine 7 can be changed, which facilitates the tension test at different positions of the nonwoven fabric and improves the test quality.

[0030] When measuring nonwoven yarn, the two ends of the nonwoven yarn are wound onto winding post 16 and winding post 27 respectively. Then, the starting motor 3 drives the threaded rod 2 to rotate, so that the moving seat 4 and the tensile testing machine 7 on the crossbeam 5 move synchronously, increasing the distance between them and the fixed rod 11. The tension test result is obtained through the tensile testing machine 7. Furthermore, by setting up two tensile testing machines 7, two tests can be performed simultaneously or comparative tests can be performed, improving the practicality of the device. At this point, the entire workflow is completed.
