Description

Technical Field

[0001] This utility model relates to the field of single yarn strength testing technology, and in particular to a fully automatic single yarn strength testing machine for nylon yarn production. Background Technology

[0002] The fully automatic single yarn strength tester is an automated testing device designed specifically for chemical fiber filaments. It is mainly used to determine the mechanical properties of a single nylon filament and other chemical fibers, such as breaking strength and breaking elongation.

[0003] In the prior art, for example, Chinese patent application publication number CN202837096U, patent application title: A novel single yarn strength machine, its structure includes an upper clamp, a lower clamp, a yarn feeder and a robot arm, the upper clamp is located below the robot arm and the yarn feeder is installed above the robot arm.

[0004] In the existing technology, a robotic arm is used to grasp the yarn to improve the stability of the yarn during the measurement process. However, the surface of the yarn and nylon filament is relatively smooth, which makes it easy for the robotic arm to shift or fail to feed the yarn when it is grasping the yarn or nylon filament.

[0005] Meanwhile, during the strength testing of nylon filaments, broken nylon filaments are usually cleaned by using a blower to extract them. This causes the nylon filaments to easily get tangled at the output end of the blower, affecting the normal operation of the blower and making the broken nylon filaments unusable, thus reducing the cleaning efficiency after the nylon filaments break.

[0006] Therefore, we propose a fully automatic single yarn strength tester for nylon filament production to solve the problems mentioned above. Utility Model Content

[0007] By utilizing the irregular arrangement of the friction blocks, the nylon filaments can be interlaced and embedded between multiple friction blocks during the traction process, thereby increasing the frictional force during nylon filament traction detection. At the same time, the opening of the hook can limit the nylon filaments during the detection process, and the rotation of the hook can be used to wind and collect broken nylon filaments, thus solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: including a body, a friction mechanism and a collection mechanism, wherein the friction mechanism includes a rubber bladder and friction blocks, the friction blocks being evenly distributed on the outer surface of the rubber bladder, and the rubber bladder and friction blocks being used to increase the friction force during nylon filament traction and prevent the nylon filament from falling off during the traction process;

[0009] The collection mechanism includes a fitting rod and a hook. The side surface of the hook is fixedly connected to the right end of the fitting rod. The hook and fitting rod are used to wrap and collect the broken nylon filaments after the strength measurement, so as to facilitate the unified collection of the broken nylon filaments in the later stage.

[0010] Preferably, the friction mechanism further includes a sliding plate, a counterweight is provided on the side surface of the sliding plate, the side surface of the counterweight is connected to a rubber bladder, a fixing rod is sleeved on the outer surface of the rubber bladder, and an opening is provided on the outer surface of the fixing rod.

[0011] Preferably, the collecting mechanism further includes a connecting seat, the interior of which is fitted with a fitting rod, and the upper surface of the connecting seat is threaded with a threaded rod, the bottom end of which is threaded with the fitting rod.

[0012] Preferably, a first wire plate is fixedly connected to the upper surface of the machine body, a movable seat is fixedly connected to the upper surface of the machine body, an electric push rod is provided on the rear surface of the movable seat, a movable plate is fixedly connected to the output end of the electric push rod, a second wire plate is fixedly connected to the upper surface of the movable plate and the second wire plate is located in front of the first wire plate, a miniature cylinder rod is provided on the front surface of the movable plate, a winding plate is fixedly connected to the front surface of the movable plate and the winding plate is located below the miniature cylinder rod.

[0013] Preferably, the front surface of the machine body is connected to a limiting seat by bolts and threads. A first motor is fixedly connected inside the limiting seat, and the output end of the first motor is fixedly connected to the connecting seat. A mounting box is fixedly connected to the front surface of the machine body. A measuring roller is provided inside the mounting box and is located below the limiting seat. A second motor is provided inside the machine body, and the output end of the second motor is fixedly connected to the measuring roller.

[0014] Preferably, a rotating plate is provided on the side surface of the machine body, a swing rod is fixedly connected to the side surface of the rotating plate, a traction rod is fixedly connected to the front end of the swing rod, and the interior of the traction rod is slidably connected to the slide plate. A stop block is fixedly connected to the left end of the fixed rod. A third motor is provided inside the machine body, and the output end of the third motor is fixedly connected to the rotating plate.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, the sliding connection between the sliding plate and the traction rod is utilized. When the swing rod and the traction rod are swinging, the sliding plate can drive the counterweight block to shake slightly inside the traction rod, squeezing the rubber bladder. This causes the traction rod to expand during the swinging process, allowing the friction blocks on the surface of the rubber bladder to extend out of the fixed rod through the opening. The irregular arrangement of the friction blocks allows the nylon filaments to interlock and embed between multiple friction blocks during the traction process, thereby increasing the friction force during the traction detection of the nylon filaments and making the nylon filaments more stable during the traction process.

[0017] 2. In this utility model, since the front surface of the hook has a notch, the nylon filament extending vertically into the limit seat can enter the interior of the hook. After the strength of the nylon filament is measured, the nylon filament can break, so that the broken end of the nylon filament can always remain inside the hook. Connect the first motor to the external power supply, start the first motor to drive the hook to rotate, and use the rotation of the hook to wind the broken nylon filament. Through the continuous winding of the nylon filament by the hook, the tension of the nylon filament will continuously increase. The nylon filament wrapped on the surface of the winding plate can break and be completely rolled into the interior of the hook. After the nylon filament is collected, the threaded rod can be turned to separate the fitting rod from the connecting seat and uniformly process the nylon filament wrapped on the surface of the hook.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as shown in the attached document Figure 1 , Figure 3 and Figure 4 As shown, it includes a body 1, a friction mechanism 15 and a collection mechanism 17. The friction mechanism 15 includes a rubber bladder 155 and friction blocks 152. The friction blocks 152 are evenly distributed on the outer surface of the rubber bladder 155. The rubber bladder 155 and the friction blocks 152 are used to increase the friction force when the nylon filament is pulled, and to prevent the nylon filament from falling off during the pulling process.

[0026] The collection mechanism 17 includes a fitting rod 173 and a hook 174. The side surface of the hook 174 is fixedly connected to the right end of the fitting rod 173. The hook 174 and the fitting rod 173 are used to wrap and collect the broken nylon filaments after the strength measurement, so as to facilitate the unified collection of the broken nylon filaments in the later stage.

[0027] The overall effect of embodiment 1 is as follows: by using the irregular arrangement of the friction blocks 152, the nylon filaments can be interlaced and embedded between multiple friction blocks 152 during the traction process, which can improve the friction force during the traction detection of the nylon filaments. At the same time, the opening 153 of the hook 174 can limit the nylon filaments during the detection process, and the rotation of the hook 174 can be used to wind and collect the broken nylon filaments being measured.

[0028] Example 2, as Figure 1 and Figure 4As shown, the friction mechanism 15 also includes a slide plate 151. A counterweight 156 is provided on the side surface of the slide plate 151. The side surface of the counterweight 156 is connected to the rubber bladder 155. A fixing rod 154 is sleeved on the outer surface of the rubber bladder 155. An opening 153 is provided on the outer surface of the fixing rod 154. A rotating plate 14 is provided on the side surface of the machine body 1. A swing rod 13 is fixedly connected to the side surface of the rotating plate 14. A traction rod 10 is fixedly connected to the front end of the swing rod 13. The interior of the traction rod 10 is slidably connected to the slide plate 151. A stop block 9 is fixedly connected to the left end of the fixing rod 154. A third motor 19 is provided inside the machine body 1. The output end of the third motor 19 is fixedly connected to the rotating plate 14.

[0029] The overall effect achieved in Embodiment 2 is as follows: Connecting the third motor 19 to an external power source and starting the third motor 19 causes the swing rod 13 and the traction rod 10 to move together, fitting the traction plate into the groove in front of the moving plate 5. By moving the moving plate 5, the fixed rod 154 can be aligned with the nylon filament to be measured. Starting the third motor 19 again causes the swing rod 13 and the traction rod 10 to swing back and forth, allowing the traction rod 10 to extend out from the groove, while the fixed nylon filament can be fitted into the surface of the fixed rod 154. The sliding connection between the sliding plate 151 and the inside of the traction rod 10 is utilized. When the swing rod 13 and the traction rod 10 swing, the slide plate 151 can drive the counterweight 156 to shake slightly inside the traction rod 10, squeezing the rubber bladder 155. This causes the traction rod 10 to expand during the swing, allowing the friction blocks 152 on the surface of the rubber bladder 155 to extend through the opening 153 into the interior of the fixed rod 154. By utilizing the irregular arrangement of the friction blocks 152, the nylon filaments can be interlaced and embedded between multiple friction blocks 152 during the traction process, which can improve the friction force during the traction detection of the nylon filaments, making the nylon filaments more stable during the traction process.

[0030] Example 3, as Figure 1 and Figure 3 As shown, the collecting mechanism 17 also includes a connecting seat 171. The interior of the connecting seat 171 is fitted with the fitting rod 173. The upper surface of the connecting seat 171 is threaded with a threaded rod 172, and the bottom end of the threaded rod 172 is threaded with the fitting rod 173. The front surface of the body 1 is threaded with a limiting seat 8 by bolts. The interior of the limiting seat 8 is fixedly connected with a first motor 16, and the output end of the first motor 16 is fixedly connected with the connecting seat 171.

[0031] The effect achieved by the entire embodiment 3 is as follows: When the nylon filament is being measured, the nylon filament can enter vertically between the measuring roller 11 and the interior of the limiting seat 8. Since the front surface of the hook 174 has a notch, the nylon filament extending vertically into the interior of the limiting seat 8 can enter the interior of the hook 174. After the strength measurement of the nylon filament is completed, the nylon filament can break, so that the broken end of the nylon filament can always remain inside the hook 174. The first motor 16 is connected to an external power source, and starting the first motor 16 can drive the hook 174 to rotate. The rotation of the hook 174 can be used to wind the broken nylon filament. Through the continuous winding of the nylon filament by the hook 174, the tension of the nylon filament continuously increases. The nylon filament wrapped on the surface of the winding plate 7 can break and be completely wound into the interior of the hook 174. After the nylon filament is collected uniformly, the threaded rod 172 can be turned to separate the fitting rod 173 from the connecting seat 171 and uniformly process the nylon filament wrapped on the surface of the hook 174.

[0032] Example 4, as Figures 1-2 As shown, a first wire plate 3 is fixedly connected to the upper surface of the machine body 1, a movable seat 2 is fixedly connected to the upper surface of the machine body 1, an electric push rod 20 is provided on the rear surface of the movable seat 2, a movable plate 5 is fixedly connected to the output end of the electric push rod 20, a second wire plate 4 is fixedly connected to the upper surface of the movable plate 5, and the second wire plate 4 is located in front of the first wire plate 3, a miniature cylinder rod 6 is provided on the front surface of the movable plate 5, a winding plate 7 is fixedly connected to the front surface of the movable plate 5, and the winding plate 7 is located below the miniature cylinder rod 6, a mounting box 12 is fixedly connected to the front surface of the machine body 1, a measuring roller 11 is provided inside the mounting box 12, and the measuring roller 11 is located below the limit seat 8, a second motor 18 is provided inside the machine body 1, and the output end of the second motor 18 is fixedly connected to the measuring roller 11.

[0033] The overall effect achieved in Embodiment 4 is as follows: When the nylon filament is being measured for strength, the nylon filament can be passed through the interior of the first filament plate 3 and the second filament plate 4 respectively. Utilizing the air pressure effect of the micro cylinder rod 6, the nylon filament passing through the interior of the second filament plate 4 is placed behind the micro cylinder rod 6. Releasing the micro cylinder rod 6 allows it to be reset under air pressure, compressing the nylon filament. Part of the nylon filament can be wound inside the winding plate 7. By starting the third motor 19, the swing rod 13 and the traction rod 10 can move together, fitting the traction plate into the groove in front of the moving plate 5. By moving the moving plate 5, the fixed rod 154 can be aligned with the part to be measured. The nylon filaments are matched accordingly. The third motor 19 is restarted to drive the swing rod 13 and the traction rod 10 to swing back and forth, so that the traction rod 10 can extend out from the inside of the groove, and the fixed nylon filaments can be embedded in the surface of the fixed rod 154. By swinging the swing rod 13, the traction rod 10 can pull the nylon filaments between the two sets of measuring rollers 11. The second motor 18 is connected to the external power supply. Starting the second motor 18 can drive the measuring rollers 11 to rotate. According to the rotation of the measuring rollers 11, the nylon filaments can be conveyed and pulled to detect the strength of the nylon filaments. After the strength of the nylon filaments is detected, the measured nylon filaments can be broken and collected inside the hook 174.

[0034] The working principle of the entire device is as follows: Nylon filaments can be passed through the interior of the first filament plate 3 and the second filament plate 4 respectively. Using the air pressure of the micro cylinder rod 6, the nylon filaments passing through the interior of the second filament plate 4 are placed behind the micro cylinder rod 6. The micro cylinder rod 6 is released, so that it can be reset by air pressure to squeeze the nylon filaments. Some of the nylon filaments can be wound inside the winding plate 7. By starting the third motor 19, the swing rod 13 and the traction rod 10 can move together, and the traction plate is fitted into the groove in front of the moving plate 5. By moving the moving plate 5, the fixed rod 154 can be aligned with the nylon filament to be measured.

[0035] Restarting the third motor 19 causes the swing rod 13 and the traction rod 10 to swing back and forth, allowing the traction rod 10 to extend from the inside of the groove. The fixed nylon thread can be embedded in the surface of the fixed rod 154. Utilizing the sliding connection between the sliding plate 151 and the inside of the traction rod 10, when the swing rod 13 and the traction rod 10 are swinging, the sliding plate 151 can cause the counterweight 156 to shake slightly inside the traction rod 10, squeezing the rubber bladder 155. This causes the traction rod 10 to expand during the swinging process, allowing the friction block 152 on the surface of the rubber bladder 155 to extend through the opening 153 into the inside of the fixed rod 154. The irregular arrangement of the friction block 152 allows it to... During the nylon filament traction process, the nylon filaments can be interlocked and embedded between multiple friction blocks 152. By swinging the swing rod 13, the traction rod 10 can pull the nylon filaments between two sets of measuring rollers 11. Starting the second motor 18 can drive the measuring rollers 11 to rotate. Based on the rotation of the measuring rollers 11, the nylon filaments can be conveyed and pulled to detect the strength of the nylon filaments. Starting the first motor 16 can drive the hook 174 to rotate. By rotating the hook 174, it can wrap the broken nylon filaments. Through the continuous wrapping of the nylon filaments by the hook 174, the tension of the nylon filaments continuously increases. The nylon filaments wrapped on the surface of the winding plate 7 can break and be completely wound into the interior of the hook 174.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
