Description

Technical Field

[0001] This application relates to the technical field of static tensile force detection, and particularly to a static tensile force detection device. Background Art

[0002] The static tensile force test requirement for non-woven handles is to hang the sample at a preset height from the ground and for a preset time without falling, and the sample is defined as a qualified product.

[0003] In the related art, a hanging bracket is provided, and multiple hanging ends are provided on the hanging bracket. Gravity sensors are provided on the multiple hanging ends. Multiple non-woven handles are hung on the gravity sensors. After the non-woven handle breaks and falls off the gravity sensor, the gravity sensor sends a signal and alarms, and the staff starts timing to detect whether the non-woven handle is qualified. At different temperatures, the mechanical properties of non-woven handles are different, and different temperature environments affect the test results, but the related art does not provide a stable temperature environment for detection, which affects the accuracy of the test. Utility Model Content

[0004] In view of this, this application provides a static tensile force detection device to solve or improve the problem that the sample cannot be detected in a stable temperature environment.

[0005] This application provides a static tensile force detection device, including:

[0006] An incubator;

[0007] A lifting device, placed at the inner bottom of the incubator, and multiple hanging parts are provided at the lifting end of the lifting device;

[0008] Multiple gravity sensing hooks for hanging samples are respectively installed on the multiple hanging parts. When the sample is hung on the gravity sensing hook, the gravity sensing hook sends a start signal, and when the sample is separated from the gravity sensing hook, the gravity sensing hook sends a stop signal;

[0009] Multiple timers are respectively electrically connected to the multiple gravity sensing hooks to calculate the time difference between the start signal and the stop signal.

[0010] Beneficial effects: Place the lifting device inside the incubator, hang multiple samples on multiple gravity-sensing hooks one by one, activate the gravity-sensing hooks, the gravity-sensing hooks send a start signal to the counter, and the corresponding timer starts timing. The lifting device rises upward so that the sample reaches a preset height from the bottom of the incubator. When the sample breaks during the detection process and detaches from the gravity-sensing hook, the weight suspended on the gravity-sensing hook changes. At this time, it is determined that the sample has fallen, and a stop signal is sent, and the corresponding timer stops timing. The timer can calculate the time difference between the start signal and the stop signal. If the time difference between the start signal and the stop signal is less than the preset time, the product is unqualified; if the time difference between the start signal and the stop signal is greater than the preset time, the product is qualified. The incubator can provide a stable temperature environment and improve the detection accuracy of the sample.

[0011] In an optional embodiment, a temperature adjustment module is provided inside the incubator for adjusting the temperature inside the incubator.

[0012] In an optional embodiment, a gravity-sensing device is further included. The gravity-sensing device is installed on the inner bottom of the incubator, the lifting device is placed on the gravity-sensing device, and the gravity-sensing device is electrically connected to multiple gravity-sensing hooks.

[0013] When the sample to be tested breaks and detaches from the gravity-sensing hook and falls on the gravity-sensing device, the gravity-sensing device is induced, detects that a sample has fallen, and transmits the signal to multiple gravity-sensing hooks. The gravity-sensing hook corresponding to the fallen sample receives the signal, and combines with the gravity sensing of the gravity-sensing hook itself to determine that the sample has detached. At this time, it can be ensured that the time difference between the start signal and the stop signal recorded by the timer is the time when the sample is suspended. The gravity-sensing device and the gravity-sensing hook monitor the breakage and fall of the sample at the same time, can accurately monitor the fall of the sample, and accurately time through the timer, improving the detection accuracy.

[0014] In an optional embodiment, a sound monitoring device is further included. The sound monitoring device is installed inside the incubator for monitoring the sound emitted when the sample falls onto the gravity-sensing device, and the sound monitoring device is electrically connected to multiple gravity-sensing hooks.

[0015] The sound monitoring device is used to monitor the sound emitted when the sample drops. When a sound appears in the incubator, the sound monitoring device transmits a signal to multiple gravity sensing hooks. The gravity sensing hook corresponding to the dropped sample receives the signal, combines it with the start signal sent by the gravity sensing hook, and determines that this sound is the sound emitted due to the sample dropping. When the sound monitoring device detects a sound and transmits the sensing signal to the corresponding gravity sensing hook, and the gravity sensing device senses that an object has dropped and transmits the sensing signal to the corresponding gravity sensing hook, it is determined that the sample hanging on the gravity sensing hook has detached. Then, the time difference between the start signal and the stop signal recorded by the timer is the hanging time of the sample. By simultaneously detecting the sample dropping through the gravity sensing device and the sound monitoring device, the accuracy of monitoring the hanging time of the sample is improved.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0031] The following will describe the embodiments of the present application in conjunction with Figure 1 , describing the embodiments of the present application.

[0032] According to an embodiment of the present application, there is provided a static tensile testing device, including: an incubator 1, a lifting device 3, a plurality of gravity sensing hooks for hanging samples, and a plurality of timers.

[0033] Specifically, the incubator 1 is rotatably provided with a door 2, and the incubator 1 is provided with a heat-insulating layer inside. The lifting device 3 is placed at the inner bottom of the incubator 1, and a plurality of hanging parts are arranged at the lifting end of the lifting device 3; a plurality of gravity-sensing hooks are respectively installed on the plurality of hanging parts. When a sample is hung on the gravity-sensing hook, the gravity-sensing hook emits a start signal. When the sample is separated from the gravity-sensing hook, the gravity-sensing hook emits a stop signal; a plurality of timers are electrically connected to the plurality of gravity-sensing hooks respectively to calculate the time difference between the start signal and the stop signal.

[0034] Place the lifting device 3 inside the incubator 1, hang a plurality of samples on the plurality of gravity-sensing hooks respectively, activate the gravity-sensing hooks, the gravity-sensing hooks send a start signal to the counter, and the corresponding timer starts timing. The lifting device 3 rises upward so that the sample reaches a preset height from the bottom of the incubator 1. When the sample breaks during the detection process and separates from the gravity-sensing hook, the weight hanging on the gravity-sensing hook changes. At this time, it is determined that the sample has fallen, and a stop signal is sent. The corresponding timer stops timing. The timer can calculate the time difference between the start signal and the stop signal. If the time difference between the start signal and the stop signal is less than the preset time, the product is unqualified. If the time difference between the start signal and the stop signal is greater than the preset time, the product is qualified. The incubator 1 can provide a stable temperature environment to improve the detection accuracy of the sample.

[0035] It should be noted that the preset height is more than 10 cm from the inner bottom of the incubator 1. The preset time can be set to 10 hours, 12 hours, 15 hours, 18 hours or any length of time according to different detection standards.

[0036] The sample for detection using this device is a non-woven fabric handle. The non-woven fabric handle is hung on the gravity-sensing hook to detect the static tensile force of the non-woven fabric handle, improve the standardization and timeliness of the static tensile force test of the non-woven fabric handle, improve the operation efficiency, and improve the accuracy of the inspection work.

[0037] In one embodiment, a display screen 8 electrically connected to the plurality of gravity-sensing hooks is arranged on the incubator 1, which can display the weight hanging on the gravity-sensing hook for the convenience of workers to view.

[0038] It should be noted that the gravity-sensing hook can monitor the gravity hanging on its hook. When the gravity hanging on the hook changes, it can send a signal to the timer. The timer uses an electronic timer and can start or stop timing according to the received signal.

[0039] In one embodiment, a temperature adjustment module is provided inside the incubator 1 for adjusting the temperature inside the incubator 1. The adjustment module controls the temperature inside the incubator 1 within the range of 34°C to 38°C, which is more in line with the temperature of the sample usage environment and improves the accuracy of the detection data.

[0040] More specifically, the temperature adjustment module can control the temperature by heating with an electric heating wire, or can adjust the temperature through a compressor (the same principle as air-conditioning heating).

[0041] In a specific embodiment, the temperature inside the incubator 1 is set to 34°C or 36°C or 38°C, and the sample is tested in an environment of 34°C or 36°C or 38°C, which is beneficial to reflecting the more real mechanical strength of the sample.

[0042] It should be noted that placing the lifting device 3 inside the incubator 1 can ensure that the sample is tested in an environment with a temperature of 34 to 38°C, reducing the interference of the outside world on the detection.

[0043] In one embodiment, a gravity sensing device 4 is further included. The gravity sensing device 4 is installed at the inner bottom of the incubator 1, the lifting device 3 is placed on the gravity sensing device 4, and the gravity sensing device 4 is electrically connected to a plurality of gravity sensing hooks.

[0044] When the sample to be tested breaks and falls off the gravity sensing hook onto the gravity sensing device 4, the gravity sensing device 4 is induced, detects that a sample has fallen, and transmits a signal to the plurality of gravity sensing hooks. The gravity sensing hook corresponding to the fallen sample receives the signal, and combines the gravity sensing of the gravity sensing hook itself to determine that the sample has detached. At this time, it can be ensured that the time difference between the start signal and the stop signal recorded by the timer is the hanging time of the sample. The gravity sensing device 4 and the gravity sensing hooks simultaneously monitor the breakage and fall of the sample, can accurately monitor the fall of the sample, and accurately time through the timer, improving the accuracy of the detection.

[0045] In a specific embodiment, a temperature monitoring screen 9 is provided on the incubator 1, which can display the temperature inside the incubator 1, facilitating the adjustment of the temperature inside the incubator 1.

[0046] In a specific embodiment, a plurality of pulleys 7 are provided at the bottom of the incubator 1, facilitating the movement of the incubator 1.

[0047] In a specific embodiment, an alarm is further included. The alarm is electrically connected to the gravity sensing device 4. When the gravity sensing device 4 senses the fall of a sample, it transmits a signal to the alarm, and the alarm sounds an alarm so that the staff can quickly respond and start the re-inspection and verification work to ensure the timeliness of the inspection.

[0048] In one embodiment, it further includes a sound monitoring device. The sound monitoring device is installed inside the incubator 1 for monitoring the sound emitted when the sample drops onto the gravity sensing device 4. The sound monitoring device is electrically connected to a plurality of gravity sensing hooks.

[0049] The sound monitoring device is used to monitor the sound emitted when the sample drops. When a sound appears inside the incubator 1, the sound monitoring device transmits a signal to a plurality of gravity sensing hooks. The gravity sensing hook corresponding to the dropped sample receives the signal, and combines with the start signal sent by the gravity sensing hook to determine that this sound is the sound emitted due to the dropping of the sample. When the sound monitoring device detects a sound and transmits the sensing signal to the corresponding gravity sensing hook, and the gravity sensing device 4 senses that an object has dropped and transmits the sensing signal to the corresponding gravity sensing hook, it is determined that the sample hanging on the gravity sensing hook has fallen off. Then, the time difference between the start signal and the stop signal recorded by the timer is the hanging time of the sample. By detecting the dropping of the sample simultaneously through the gravity sensing device 4 and the sound monitoring device, the accuracy of monitoring the hanging time of the sample is improved.

[0050] In one embodiment, the lifting device 3 includes a connecting frame 31, a lifting mechanism 32, and a hanging frame 33. The connecting frame 31 is placed on the gravity sensing device 4, the lifting mechanism 32 is installed on the connecting frame 31, and the hanging frame 33 is connected to the lifting end of the lifting mechanism 32. A plurality of hanging parts are provided on the hanging frame 33.

[0051] The lifting mechanism 32 can drive the hanging frame 33 to move up and down, adjusting the distance between the sample hanging on the gravity sensing hook and the bottom of the incubator 1, which is convenient to meet the experimental requirements. And the connecting frame 31 is placed on the gravity sensing device 4 to ensure that the sample can fall onto the gravity sensing device 4 after dropping, improving the accuracy of sample dropping monitoring.

[0052] More specifically, the lifting mechanism 32 can be a cylinder, and the hanging frame 33 is installed at one end of the piston rod of the cylinder.

[0055] In a specific embodiment, three hanging rods 332 are provided, and six hanging parts are provided on the three hanging rods 332. Multiple samples can be detected simultaneously in a single experiment.

[0056] In one embodiment, the suspension rod 332 is a telescopic rod, and the telescopic end of the telescopic rod is provided as a suspension portion.

[0057] In a specific embodiment, the diameter of the suspension portion is 2.5 cm to 3.5 cm.

[0058] It should be noted that the suspension rod 332 being a telescopic rod facilitates adjusting the distance between two adjacent suspension portions, making it convenient to hang samples, and after the detection, it is also convenient for storage.

[0059] In one embodiment, the lifting mechanism 32 includes a mounting base 321, a rack 322, a motor, and a gear. The mounting base 321 is connected to the connecting frame 31. The mounting base 321 is provided with a guiding groove along the lifting direction of the lifting end of the lifting mechanism 32. The rack 322 is slidably connected in the guiding groove. The motor is connected to the mounting base 321. The gear is mounted on the output shaft of the motor and is in transmission connection with the rack 322. The connecting rod 331 is connected to the rack 322.

[0060] The motor drives the gear to rotate. The gear drives the rack 322 to slide in the guiding groove. The rack 322 drives the connecting rod 331 to move up and down, and further drives the suspension rod 332 to move up and down.

[0061] In one embodiment, a plurality of driving wheels 5 are mounted on the connecting frame 31 to drive the connecting frame 31 to enter and leave the incubator 1.

[0062] In a specific embodiment, there are two lifting mechanisms 32. The connecting frame 31 includes two fixed rods. The mounting bases 321 of the two lifting mechanisms 32 are respectively connected to the two fixed rods. One ends of the two racks 322 are connected to both ends of the suspension rod 332. A plurality of driving wheels 5 are mounted on the two fixed rods.

[0063] In one embodiment, there is also a conveying plate 6 for the connecting frame 31 to enter the incubator 1. One side of the conveying plate 6 is rotatably connected to the bottom side of the incubator 1, and the other side abuts against the ground.

[0064] A plurality of driving wheels 5 are mounted on the connecting frame 31, and the plurality of driving wheels 5 slide along the conveying plate 6, facilitating the connecting frame 31 to enter and leave the incubator 1.

[0065] In a specific embodiment, the driving wheel 5 includes a wheel body and a motor. The wheel body is rotatably connected to the bottom of the incubator 1 through a connecting member. The motor drives the wheel body to rotate to drive the connecting frame 31 to enter or leave the incubator 1.

[0066] In a specific embodiment, there is also a cylinder. The cylinder barrel of the cylinder is hinged to the bottom side of the incubator 1, and the telescopic rod of the cylinder is hinged to the bottom surface of the conveying plate 6 to drive the conveying plate 6 to rotate, facilitating the connecting frame 31 to enter and leave the incubator 1.

[0067] The following takes an embodiment to comprehensively elaborate on Figure 1 all of the above solutions.

[0068] The heating wire in the incubator 1 is heated, and the temperature in the incubator 1 is set at 36°C. The air cylinder drives the conveying plate 6 to rotate. One side end of the conveying plate 6 abuts against the ground. Multiple samples are respectively hung on multiple gravity-sensing hooks. When the temperature reaches the set temperature, the door 2 is opened. Multiple driving wheels 5 drive the connecting frame 31 into the incubator 1 and move to the gravity-sensing device 4, and then the door 2 is closed. The motor drives the gear to rotate, and the gear drives the rack 322 to slide in the guide groove. The rack 322 drives the connecting rod 331 to move up and down, and further drives the suspension rod 332 to move up and down, so that the sample is more than 10 cm away from the bottom of the incubator 1. The gravity-sensing hook is started, and the gravity-sensing hook sends a start signal to the counter, and the corresponding timer starts timing. When the sample breaks during the detection process and detaches from the gravity-sensing hook, the weight suspended on the gravity-sensing hook changes, and a stop signal is sent to the timer. At the same time, the sample falls on the gravity-sensing device 4. The gravity-sensing device 4 senses the gravity and the sound monitoring device detects the sound of the sample falling. At this time, it is determined that the sample has fallen, and the time difference between the start signal and the stop signal is recorded. If the time difference between the start signal and the stop signal is greater than the preset time, the product is qualified. The incubator 1 can provide a stable temperature environment and improve the detection accuracy of the sample.
