Technical Field

[0001] This utility model relates to the field of toughness testing devices, and in particular to a cotton fiber toughness testing device. Background Technology

[0002] Cotton is an important economic crop, belonging to the genus Gossypium of the Malvaceae family. Its seed fiber is a major raw material for the textile industry, possessing excellent moisture absorption and warmth retention properties. Cotton is widely cultivated in my country, especially in the Yellow River and Yangtze River basins, and is a vital resource related to the national economy and people's livelihood.

[0003] To test the quality of cotton, cotton fiber toughness testing equipment is needed. Most fiber toughness testing equipment uses the traditional winding sample fixing method when testing cotton fibers. This method is time-consuming, labor-intensive, and extremely inconvenient for loading and unloading, resulting in low testing efficiency and reducing the practicality of the equipment.

[0004] Therefore, those skilled in the art have provided a cotton fiber toughness testing device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cotton fiber toughness testing device. The device rotates a worm gear within a fixed cylinder by twisting the handle. This causes the worm wheel, meshing with the worm gear, to rotate, which in turn rotates the second bevel gear fixedly connected to the worm wheel within the protective housing. This, in turn, causes the first bevel gear to mesh with the second bevel gear, rotating the first threaded rod. The first threaded rod rotates with the lower clamping block as its base point, causing the upper clamping block mounted on it to move up and down. One end of the cotton fiber to be tested is placed on a roughened pad on the lower clamping block, and then the upper clamping block is manipulated to hold and fix the cotton fiber there. This achieves convenient fixing, improves testing efficiency, and enhances the practicality of the device.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A cotton fiber toughness testing device includes a fixed clamping mechanism, a pulling mechanism, and a controller. The fixed clamping mechanism is fixedly connected to one end of the ground surface of the pulling mechanism. The controller is located on one side of the pulling mechanism. The fixed clamping mechanism includes a base. A lower clamping block is fixedly connected to the middle of the upper surface of the base. A guide block is fixedly connected to one end of the upper surface of the lower clamping block. A first threaded rod is rotatably connected to the middle of the upper surface of the lower clamping block. A first bevel gear is fixedly connected to the upper end of the first threaded rod. An upper clamping block is sleeved on the outer wall of the first threaded rod. A second bevel gear is meshed with one side of the outer wall of the first bevel gear. A worm gear is fixedly connected to one side of the second bevel gear. A worm is meshed with one side of the outer wall of the worm gear. A handle is fixedly connected to the upper end of the worm. A fixed cylinder is rotatably connected to the lower end of the worm. A roughened pad is located on one side of each of the upper and lower clamping blocks. A protective shell is fixedly connected to one end of the upper surface of the base.

[0008] Through the above technical solution, the equipment rotates the worm gear inside the fixed cylinder by twisting the handle. At this time, the worm wheel, which is meshed with the worm gear, also rotates, causing the second bevel gear, which is fixedly connected to the worm wheel inside the protective shell, to rotate. As a result, the first bevel gear meshes with the second bevel gear and rotates, causing the first threaded rod to rotate. The first threaded rod rotates with the lower clamping block as the base point, causing the upper clamping block sleeved on it to move up and down. One end of the cotton fiber to be tested is placed on the rough pad block set on the lower clamping block, and then the upper clamping block is manipulated to clamp and fix the cotton fiber on it. This achieves convenient fixation, improves the testing efficiency, and enhances the practicality of the equipment.

[0009] Furthermore, the pulling mechanism includes a slide block, a groove is provided in the middle of one side of the outer wall of the slide block, a servo motor is provided at one end of the slide block, a second threaded rod is fixedly connected to the output end of the servo motor, a slider is sleeved on the outer wall of the second threaded rod, a guide post is fixedly connected to the upper end of the slider, a tension sensor is slidably connected to one side of the outer wall of the guide post, a receiving platform is fixedly connected to the middle of the upper end face of the slide block, and a dustproof shell is sleeved around the outer wall of the servo motor;

[0010] Through the above technical solution, the equipment uses a controller to control a servo motor to drive the second threaded rod to rotate in the groove set inside the slide block. The rotation of the second threaded rod causes the slider to slide simultaneously on the groove and the receiving platform to maintain stability. The tension sensor on it can also slide along with it, fixing the other end of the cotton fiber to be tested on the tension sensor. Then, the controller can make the servo motor stably control the speed and direction of the second threaded rod to stretch the cotton fiber and test its toughness, realizing automatic and controllable detection, improving detection efficiency and enhancing the practicality of the equipment.

[0011] Furthermore, one end of the upper clamping block is slidably connected to the guide block;

[0012] The above technical solution enables the upper clamping block to move stably without deflection.

[0013] Furthermore, the first threaded rod is rotatably connected to the middle of the lower end face of the protective shell, and one end of the second bevel gear is rotatably connected to the middle of one side end face of the protective shell;

[0014] Through the above technical solution, this setting enables the protective shell to protect the first and second bevel gears from the influence of the external environment and to provide fixed support for the second bevel gear and the worm gear.

[0015] Furthermore, the fixed cylinder is fixedly connected to one side of the upper end face of the base;

[0016] Through the above technical solution, this setting makes the fixed cylinder the rotation base point of the worm gear.

[0017] Furthermore, one end of the second threaded rod is rotatably connected to one end of the inner side of the groove;

[0018] Through the above technical solution, this setting enables the second threaded rod to have a stable rotation fulcrum.

[0019] Furthermore, a slider is slidably connected to one side of the outer wall of the receiving platform, and the lower end face of the receiving platform completely covers the upper end of the slide groove.

[0020] The above technical solution enables the slider to slide stably along the receiving platform direction and prevents cotton fibers from falling into the chute and affecting the operation of the equipment.

[0021] Furthermore, the fixed height of the tension sensor on one side of the guide column outer wall is adjusted by bolts;

[0022] Through the above technical solution, this setting enables the tension sensor to adjust the fixed height in a timely manner according to the thickness of the cotton fibers being clamped.

At this time, the worm wheel connected to the worm gear also rotates, causing the second bevel gear fixedly connected to the worm wheel inside the protective shell to rotate. As a result, the first bevel gear meshes with the second bevel gear and rotates, causing the first threaded rod to rotate. The first threaded rod rotates with the lower clamping block as the base point, causing the upper clamping block sleeved on it to move up and down. One end of the cotton fiber to be tested is placed on the rough surface pad provided on the lower clamping block.

Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1-3 One specific embodiment provided by this utility model:

[0035] A cotton fiber toughness testing device includes a fixed clamping mechanism 1, a pulling mechanism 2, and a controller 3. The fixed clamping mechanism 1 is fixedly connected to one end of the ground surface of the pulling mechanism 2, and the controller 3 is located on one side of the pulling mechanism 2. The fixed clamping mechanism 1 includes a base 101. A lower clamping block 102 is fixedly connected to the middle of the upper surface of the base 101. A guide block 103 is fixedly connected to one end of the upper surface of the lower clamping block 102. A first threaded rod 104 is rotatably connected to the middle of the upper surface of the lower clamping block 102. A first bevel gear 105 is fixedly connected to the upper end of the first threaded rod 104. An upper clamping block 106 is sleeved on the outer wall of the first threaded rod 104. A second bevel gear 107 is meshed with one side of the outer wall of the first bevel gear 105. A worm gear 108 is fixedly connected to one side of the second bevel gear 107. A worm 109 is meshed with one side of the outer wall of the worm gear 108. A handle 110 is fixedly connected to the upper end of the worm 109. The lower end is rotatably connected to a fixed cylinder 111. One end of the upper clamping block 106 and the lower clamping block 102 is provided with a rough surface pad 112. One end of the upper surface of the base 101 is fixedly connected to a protective shell 113. The device rotates the worm 109 in the fixed cylinder 111 by twisting the handle 110. At this time, the worm wheel 108, which is meshed with the worm 109, also rotates, causing the second bevel gear 107, which is fixedly connected to the worm wheel in the protective shell 113, to rotate. As a result, the first bevel gear 105 meshes with the second bevel gear 107 and rotates, causing the first threaded rod 104 to rotate. The first threaded rod 104 rotates with the lower clamping block 102 as the base point, causing the upper clamping block 106 sleeved on it to move up and down. One end of the cotton fiber to be tested is placed on the rough surface pad 112 provided on the lower clamping block 102. Then, the upper clamping block 106 is manipulated to clamp and fix the cotton fiber on it, which realizes convenient fixation, improves detection efficiency and enhances the practicality of the device.

[0036] Reference Figure 3-5The traction mechanism 2 includes a slide block 201. A groove 202 is formed in the middle of one side of the outer wall of the slide block 201. A servo motor 203 is installed at one end of the slide block 201. A second threaded rod 204 is fixedly connected to the output end of the servo motor 203. A slider 205 is fitted onto the outer wall of the second threaded rod 204. A guide post 206 is fixedly connected to the upper end of the slider 205. A tension sensor 207 is slidably connected to one side of the outer wall of the guide post 206. A receiving platform 208 is fixedly connected to the middle of the upper surface of the slide block 201. A dustproof shell 209 is fitted around the outer wall of the servo motor 203. The device is controlled by a controller 3. The servo motor 203 drives the second threaded rod 204 to rotate in the groove 202 set in the slide block 201. The rotation of the second threaded rod 204 causes the slider 205 to slide on both the groove 202 and the receiving platform 208 to maintain stability. The tension sensor 207 on it can also slide along with it, fixing the other end of the cotton fiber to be tested on the tension sensor 207. Then the controller 3 can make the servo motor 203 stably control the speed and direction of the second threaded rod 204 to stretch the cotton fiber and test its toughness, realizing automatic and controllable detection, improving detection efficiency and enhancing the practicality of the equipment.

[0037] One end of the upper clamping block 106 is slidably connected to the guide block 103, which enables the upper clamping block 106 to move stably without deflection.

[0038] The first threaded rod 104 is rotatably connected to the middle of the lower end face of the protective shell 113, and one end of the second bevel gear 107 is rotatably connected to the middle of one side end face of the protective shell 113. This arrangement allows the protective shell 113 to protect the first bevel gear 105 and the second bevel gear 107 from the influence of the external environment and to provide fixed support for the second bevel gear 107 and the worm gear 108.

[0039] The fixed cylinder 111 is fixedly connected to one side of the upper end face of the base 101, which makes the fixed cylinder 111 the rotation base point of the worm gear 109.

[0040] One end of the second threaded rod 204 is rotatably connected to one end of the inner side of the slide groove 202. This arrangement allows the second threaded rod 204 to have a stable fulcrum for rotation.

[0041] A slider 205 is slidably connected to one side of the outer wall of the receiving platform 208. The lower end of the receiving platform 208 completely covers the upper end of the slide groove 202. This arrangement allows the slider 205 to slide stably along the direction of the receiving platform 208 and prevents cotton fibers from falling into the slide groove 202 and affecting the operation of the equipment.

[0042] The fixed height of the tension sensor 207 on one side of the outer wall of the guide post 206 is adjusted by bolts. This setting allows the tension sensor 207 to adjust the fixed height in a timely manner according to the thickness of the cotton fibers being clamped.

[0043] Working principle: The device rotates the worm gear 109 within the fixed cylinder 111 by twisting the handle 110. At this time, the worm wheel 108, which meshes with the worm gear 109, also rotates, causing the second bevel gear 107, which is fixedly connected to the worm wheel within the protective shell 113, to rotate. Consequently, the first bevel gear 105 meshes with the second bevel gear 107, causing the first threaded rod 104 to rotate. The first threaded rod 104 rotates with the lower clamping block 102 as its base point, causing the upper clamping block 106, which is fitted onto it, to move up and down. One end of the cotton fiber to be tested is placed on the roughened pad 112 provided on the lower clamping block 102. The upper clamp 106 clamps the cotton fiber to fix it. The device controls the servo motor 203 through the controller 3 to drive the second threaded rod 204 to rotate in the slide groove 202 set in the slide block 201. The rotation of the second threaded rod 204 causes the slider 205 to slide on the slide groove 202 and the receiving platform 208 at the same time to maintain stability. The tension sensor 207 on it can also slide along with it, fixing the other end of the cotton fiber to be tested on the tension sensor 207. Then the controller 3 can make the servo motor 203 stably control the speed and direction of the second threaded rod 204 to stretch the cotton fiber and test its toughness.
