An adjustment motor is installed in the transmission box. The adjustment motor is drivingly connected to a gear transmission mechanism. A transmission gear is connected to the clutch-type driving mechanism. A rack fixed to the lifting block is meshed with the transmission gear. An elastic pushing mechanism is installed at the bottom of the lifting block. A pressure sensor abutted against the elastic pushing mechanism is installed on the frame.

[0030] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0031] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the limitations of the specific embodiments disclosed below.

[0032] As Figures 1-9A strength detection device for manufacturing polypropylene fiber filaments as shown includes a detection device main body 1. At a position near the top on the front side of the detection device main body 1, a control panel 2 is fixedly connected. At the four corners of the bottom end of the detection device main body 1, support feet 3 are fixedly connected. A clamping assembly is arranged at the front end of the detection device main body 1. The clamping assembly includes an upper clamp 4 and a lower clamp 5. There are six groups of clamping assemblies. The clamping assemblies are used to clamp and fix the upper and lower ends of the polypropylene fiber filaments. The top end of the upper clamp 4 is fixedly connected to the detection device main body 1. The lower clamp 5 is arranged at the bottom end of the upper clamp 4. A split-actuated detection mechanism is arranged between the lower clamp 5 and the detection device main body 1. The split-actuated detection mechanism is used to control the movement of the six groups of clamping assemblies. By setting the cooperation of the split-actuated detection mechanism and the clamping assemblies, it can simultaneously detect multiple groups of polypropylene fiber filaments and can control the redundant clamping assemblies not to move according to the number of polypropylene fiber filaments to be detected. When only one group or a few groups of polypropylene fiber filaments need to be detected, the load of the servo motor 61 can be significantly reduced, achieving an energy-saving effect. When more clamping assemblies need to be detected, six groups of clamping assemblies can be used simultaneously to detect the polypropylene fiber filaments, effectively improving the detection efficiency of the polypropylene fiber filaments, and solving the problem that although the single-filament strength detection device in the prior art can effectively detect a single fiber, when sampling and detecting polypropylene fiber filaments, it is necessary to detect the strength of multiple polypropylene fiber filaments in multiple different batches. Using the existing device can only detect the polypropylene fiber filaments one by one, which takes a long time and has low detection efficiency.

[0033] The split-actuated detection mechanism includes a tension sensor 51. The tension sensor 51 is fixedly connected to the rear side of the lower clamp 5. A connecting block 52 is fixedly connected to the rear side of the tension sensor 51. The connecting block 52 is fixedly connected to the top end of the front side of a rack 53. The rack 53 is slidably connected inside a transmission cavity 58. The transmission cavity 58 is opened inside the detection device main body 1. The rack 53 also meshes with a gear 54. The gear 54 is arranged inside the transmission cavity 58, and a connecting rod 55 is fixedly connected to the front end of the gear 54. A rotating shaft 57 is arranged at the rear side of the gear 54, and a control component is arranged between the gear 54 and the rotating shaft 57. The control component is used to control the meshing state between the gear 54 and the rack 53. A transmission component is arranged outside the rotating shaft 57. The transmission component is used to control the rotation of the gear 54. The rear side of the rotating shaft 57 is rotatably connected to the inner wall of the transmission cavity 58. The control panel 2 is electrically connected to the servo motor 61 and the tension sensor 51, and the control panel 2 can control the operation of the servo motor 61. When six groups of polypropylene fiber filaments need to be detected simultaneously.

[0034] The front end of the connecting rod 55 penetrates through the main body 1 of the detection device and extends to the outside of the main body 1 of the detection device. A knob 56 is fixedly connected to the front end of the connecting rod 55. Anti-slip grooves are provided on the outer side of the knob 56. The anti-slip grooves provided on the outer side of the knob 56 play an effect of increasing the friction force, avoiding slipping due to too small friction force when pushing the knob 56. At the same time, the gear 54 can be manually driven to rotate through the knob 56, achieving the effect that when the transmission component of the device is damaged, the knob 56 can be used as a redundant function backup to temporarily detect the acrylic fiber filaments.

[0035] The transmission component includes a worm gear 59. The worm gear 59 meshes with a worm 60. The right side of the worm 60 is rotatably connected to the inner wall of the transmission cavity 58. The left side of the worm 60 is fixedly connected to the output shaft of the servo motor 61. The worm 60 is fixedly connected to the inner wall of the transmission cavity 58. When six groups of polypropylene fiber filaments need to be detected simultaneously, the servo motor 61 is controlled to work through the control panel 2. When the servo motor 61 drives the worm 60 to rotate, the worm gear 59 that cooperates with the worm 60 rotates synchronously. The rotation of the worm gear 59 drives the fixedly connected rotating shaft 57 to rotate synchronously, and drives the gear 54 to rotate synchronously through the control component. The rotation of the gear 54 drives the rack 53 to move, so that the rack 53 drives the tension sensor 51 and the lower fixture 5 to move downward, pulling the polypropylene fiber filament to detect the magnitude of the tension borne by the polypropylene fiber filament through the tension sensor 51 and sending the detected data to the control panel 2, achieving the effect of detecting the strength of the polypropylene fiber filament.

[0036] The control component includes a plugging shaft 62 which is fixedly connected to the central position at the rear side of the gear 54. The plugging shaft 62 is inserted into the interior of a plugging slot 63 which is opened at the front side of a rotating shaft 57. A fixed seat 64 is fixedly connected to the rear side of the inner wall of the plugging slot 63. A moving slot 65 is opened on the fixed seat 64. A moving block 66 is slidably connected to the interior of the moving slot 65. A first sliding slot 67 is opened at the top end of the moving block 66. A first sliding block 68 is slidably connected to the interior of the first sliding slot 67. The top end of the first sliding block 68 is fixedly connected to the front side of the bottom end of a hinge rod 69. The rear side of the hinge rod 69 is rotatably connected to a hinge seat 70. The hinge seat 70 is fixedly connected to the rear side of the top end of the fixed seat 64. A guiding rod 71 is fixedly connected to the rear side of the moving block 66. A spring 72 is wound around the outer side of the guiding rod 71. A push rod 73 is fixedly connected to the front side of the moving block 66. A connecting seat 75 is fixedly connected to the bottom end of the fixed seat 64. The connecting seat 75 is rotatably connected to a claw 76. A second sliding block 77 is fixedly connected to the top end of the claw 76. The second sliding block 77 is slidably connected to the interior of a second sliding slot 78 which is opened on both sides of a pulling block 79. The pulling block 79 is fixedly connected to the bottom end of the moving block 66. The claw 76 is designed in a hook shape and is engaged with a locking block 80. The locking block 80 is fixedly connected to the rear side of the plugging shaft 62. The front end of the spring 72 is fixedly connected to the rear side of the moving block 66, and the rear side of the spring 72 is fixedly connected to the rear side of the inner wall of the moving slot 65. When a certain set of pulling components is not needed, first press the knob 56 towards the detection device main body 1, so that the knob 56 moves towards the detection device main body 1 and drives the connecting rod 55 to move towards the detection device main body 1 synchronously, causing the connecting rod 55 to push the gear 54 to move. When the gear 54 moves, it pushes the plugging shaft 62 to move into the interior of the plugging slot 63. At this time, the plugging shaft 62 pushes the cushion block 74 and the push rod 73 to move. The cushion block 74 pushes the moving block 66 to move backward, causing the first sliding block 68 slidably connected to the interior of the first sliding slot 67 to slide along the shape of the first sliding slot 67. At this time, the moving block 66 simultaneously squeezes the spring 72, causing the spring 72 to further undergo elastic deformation. When the moving block 66 moves backward, the pulling block 79 fixedly connected to the bottom end of the moving block 66 drives the claw 76 to slightly rotate counterclockwise through the second sliding slot 78 and the second sliding block 77. After the first sliding block 68 slides in the interior of the first sliding slot 67, it no longer remains at the central position at the front end of the first sliding slot 67. At this time, the moving block 66 moves forward under the restoring force of the spring 72 and pushes the push rod 73 and the cushion block 74 to move forward synchronously. At the same time, the pulling block 79 fixedly connected to the bottom end of the moving block 66 also moves synchronously with the movement of the moving block 66, and through the cooperation between the second sliding slot 78 and the second sliding block 77, the claw 76 is disengaged from the engagement with the locking block 80. At this time, the plugging shaft 62 is no longer fixed,Under the thrust of the ejector rod 73 and the cushion block 74, it moves forward and drives the fixedly connected gear 54 to move forward synchronously to release the meshing state with the rack 53. At this time, when the set of gears 54 rotates, it cannot drive the corresponding lower fixture 5 to move. When the set of lower fixtures 5 needs to be used again, the knob 56 is pushed towards the main body 1 of the detection device again to make the gear 54 mesh with the rack 53. Through the control component, the effect is achieved that which several groups or a specified group of clamping components can be used to pull the polypropylene fiber filaments for detection, so that which several groups or a specified group of clamping components can be used for detection. It can make the clamping components effectively adapt to the number of polypropylene fiber filaments to be detected, and control whether to use the set of clamping components according to the number of polypropylene fiber filaments to be detected.,

[0037] The insertion shaft 62 is integrally designed in a rectangular shape, and the insertion shaft 62 fits with the insertion slot 63. Through the rectangular design, the insertion shaft 62 effectively transmits the rotation, avoiding the inability to transmit the power to the gear 54 when rotating in the first chute 67.

[0038] A cushion block 74 is fixedly connected to the front side of the ejector rod 73. The cushion block 74 is made of rubber. By using the cushion block 74 made of rubber, the collision between the insertion shaft 62 and the insertion slot 63 is buffered, avoiding damage to the insertion shaft 62 or the ejector rod 73 under the impact.

[0039] A third slider 81 is fixedly connected to the bottom end of the insertion shaft 62. The third slider 81 is slidably connected inside the third chute 82. The third chute 82 is opened on the inner wall of the bottom end of the transmission cavity 58. When the insertion shaft 62 slides, the third slider 81 fixedly connected to the insertion shaft 62 slides synchronously inside the third chute 82. Through the combination of the third slider 81 and the third chute 82, the moving distance of the insertion shaft 62 is limited, avoiding excessive movement of the insertion shaft 62 under the thrust of the ejector rod 73 and the cushion block 74.

[0040] The pulling block 79 is integrally designed in an inverted U shape, and the second chute 78 is designed in a gradually descending inclined shape from front to back.

[0041] Working principle: When it is necessary to detect six groups of polypropylene fiber filaments simultaneously, the servo motor 61 is controlled to work through the control panel 2. When the servo motor 61 drives the worm 60 to rotate, the worm wheel 59 that cooperates with the worm 60 rotates synchronously. The rotation of the worm wheel 59 drives the fixedly connected rotating shaft 57 to rotate synchronously, and drives the gear 54 to rotate synchronously through the control component. The rotation of the gear 54 drives the rack 53 to move, so that the rack 53 drives the tension sensor 51 and the lower fixture 5 to move downward, pulling the polypropylene fiber filament to detect the magnitude of the tension borne by the polypropylene fiber filament through the tension sensor 51, and sending the detected data to the control panel 2, achieving the effect of detecting the strength of the polypropylene fiber filament.

[0042] When a certain set of pulling components is not needed, first press the knob 56 towards the detection device main body 1, so that the knob 56 moves towards the detection device main body 1, and drives the connecting rod 55 to move towards the detection device main body 1 synchronously, so that the connecting rod 55 pushes the gear 54 to move. When the gear 54 moves, it pushes the insertion shaft 62 into the inside of the insertion slot 63. At this time, the insertion shaft 62 pushes the cushion block 74 and the ejector rod 73 to move. The cushion block 74 pushes the moving block 66 to move backward, so that the first slider 68 slidingly connected inside the first chute 67 slides along the shape of the first chute 67. At this time, the moving block 66 simultaneously squeezes the spring 72, causing the spring 72 to further undergo elastic deformation. When the moving block 66 moves backward, the pulling block 79 fixedly connected to the bottom end of the moving block 66 passes through the second chute 78 and the second slider 77, pulling the claw 76 to slightly rotate counterclockwise. After the first slider 68 slides inside the first chute 67, it no longer remains at the central position at the front end of the first chute 67. At this time, the moving block 66 moves forward under the restoring force of the spring 72, and pushes the ejector rod 73 and the cushion block 74 to move forward synchronously. At the same time, the pulling block 79 fixedly connected to the bottom end of the moving block 66 also moves synchronously with the movement of the moving block 66, and releases the engagement between the claw 76 and the block 80 through the cooperation between the second chute 78 and the second slider 77. At this time, the insertion shaft 62 is no longer fixed, and moves forward under the thrust of the ejector rod 73 and the cushion block 74, and drives the fixedly connected gear 54 to move forward synchronously to disengage from the engagement with the rack 53. At this time, when this set of gears 54 rotates, it cannot drive the corresponding lower fixture 5 to move. When this set of lower fixtures 5 needs to be used again, push the knob 56 towards the detection device main body 1 again to make the gear 54 and the rack 53 engage.
