Description
Technical Field
[0001] The utility model relates to the technical field of detection equipment, in particular to a novel device capable of testing the breaking duration of a tape. Background Art
[0002] A tape is a material used in many industries, such as electrical tapes and pressure-sensitive tapes for packaging, etc. In the production of tapes, manufacturers need to test the performance of tapes to ensure the quality of products leaving the factory, and end-users need to test the performance of tapes to understand the performance of the products they use. Among them, testing the strength (i.e., tensile capacity) of tapes is an important link.
[0003] In existing tape strength performance testing equipment, generally one end of the tape is fixed in a fixed seat, and the other end is fixed in a limit seat at the front side of an electric pull rod. A tensile sensor is installed between the electric pull rod and the limit seat. During measurement, the electric pull rod gradually extends the tape. At the moment when the tape breaks, the measurement personnel obtain specific tape strength data by observing in real time and reading the data on a tensile display meter connected to the signal output end of the tensile sensor through a wire. Although the existing tape strength performance testing equipment meets the testing needs to a certain extent, due to structural limitations, there are still the following technical drawbacks. Specifically, it can only obtain the tensile data at the moment when the tape breaks, and cannot effectively measure the breaking time data of the tape under a certain extension force condition (for example, in the actual application of electrical tapes, under the corresponding winding force, after multiple turns of tape winding, if it is too loose, the sealing performance is poor, and substances such as water will enter the conductive parts of related equipment, causing the insulation performance of related equipment to deteriorate; if it is wound too tightly, after a long time and due to factors such as aging, the tape may break, also resulting in poor insulation performance, etc.), which cannot effectively ensure the product quality of manufacturers; if the measurement personnel stay at the testing station in real time, although they can obtain the breaking data of the tape based on a corresponding extension force, usually in this testing mode, the breaking time of the tape is very long, so it is not practical for the measurement personnel to observe at the testing station for a long time. In summary, it is particularly necessary to provide a device that can not only measure the instantaneous breaking data of the tape, but also measure the breaking time data of the tape under a certain extension force condition. Summary of the Utility Model
[0004] In order to overcome the disadvantages of the existing tape strength performance testing equipment due to structural limitations as described in the background, the utility model provides a novel device capable of testing the breaking duration of a tape, which, under the combined action of relevant mechanisms, can not only test the instantaneous breaking data of the tape, but also obtain the breaking time data of the tape under a certain extension force condition, providing favorable technical support for relevant personnel to accurately master the extension force breaking data of the tape under various states (that is, obtaining the strength data of the tape under various states) and ensuring the product quality of manufacturers.
[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:
[0006] A device for testing the duration of tape breakage of the new type, including a bottom plate, a measuring table, an upper support frame, an electric push rod, and a pressure sensor.

There is a clamping opening at the inner end of the fixed block, a threaded hole at the upper end of the clamping opening, and the lead screw is connected to the threaded hole through a thread and is rotatably installed on the pressing plate; the fixed blocks of the two sets of the fixed clamp mechanisms and the two sides of the lower end of the upper support frame are respectively installed on the upper ends of the two sets of the measuring tables; the upper end of the electric push rod is installed on the upper end of the upper support frame, the pressure sensor is installed at the lower end of the electric push rod, and a top plate is installed at the lower end of the force-receiving surface of the pressure sensor; the display mechanism and the timing mechanism are installed in the component box, and the signal output end of the pressure sensor is electrically connected to the signal input ends of the display mechanism and the timing mechanism.
[0007] Further, there is a distance between the lower end of the pressing plate and the inner lower end of the clamping opening, and the clamping openings of the fixed blocks of the two sets of the fixed clamp mechanisms face each other on the inner side.
[0008] Further, the distance between the lower end of the fixed block of the fixed clamp mechanism and the inner lower end of the clamping opening is greater than the thickness of the tape.
[0009] Further, the display mechanism includes a voltage display meter.
[0010] Further, the timing mechanism includes an adjustable resistor, a resistor, a triode, a buzzer, a counter, and a relay that are electrically connected. One end of the adjustable resistor is connected to one end of the first resistor and one end of the second resistor. The other end of the second resistor is connected to the base of the triode. The collector of the triode is connected to the negative power input terminal of the first relay. The positive power input terminal and the control power input terminal of the first relay and the positive power input terminal of the counter are connected.

The two contacts under the counting button of the counter are connected to the control contact terminal and the normally open contact terminal of the second relay.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: Before the test, a section of the tape to be tested is fixed by the clamping openings of two sets of fixing clip mechanisms respectively. Through the power switch, the top plate is controlled to move downward to tightly press the middle part of the upper end of the tape.

To sum up, the present utility model has a good application prospect. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 、 2 As shown in 2 , the novel device for testing the fracture duration of the tape includes a bottom plate 1, a measuring table 2, an upper support frame 3, an electric push rod M1, a power switch S1, a pressure sensor A2, a power supply module A1, and further has a fixing clip mechanism 4, a display mechanism V, and a timing mechanism 5. There are two sets of the measuring tables 2, and the lower ends of the two sets of measuring tables 2 are welded to the upper parts of the left and right side ends of the bottom plate 1. The two lower sides of the "Π"-shaped upper support frame 3 are respectively welded to the middle parts of the outer sides of the upper ends of the two sets of measuring tables 2. There are two sets of the fixing clip mechanisms 4, and each set of the fixing clip mechanism 4 includes a fixing block 41, a pressing plate 42, and a manual adjustment screw rod 43. There is a "[ "-shaped clamping opening 44 at the inner side end of the rectangular fixing block. There is a threaded hole in the middle of the upper end of the clamping opening 44. A limiting ring 45 is welded to the middle of the upper end of the rectangular pressing plate. A bearing 46 is tightly sleeved inside the limiting ring 45. The lower end of the screw rod 43 is screwed into the clamping opening through the threaded hole and is located below the upper end of the clamping opening 44. The lower side of the screw rod 43 is tightly sleeved in the inner ring of the bearing 46. The fixing blocks 41 of the two sets of the fixing clip mechanisms are respectively welded horizontally to the middle parts of the upper ends of the two sets of measuring tables 2. The cylinder body of the electric push rod M1 is vertically installed in the middle of the lower side of the upper end of the upper support frame 3. The pressure sensor A2 is installed at the lower end of the push rod of the electric push rod M1 and its force-bearing surface faces downward. A top plate 6 is longitudinally welded to the lower end of the force-bearing surface of the pressure sensor A2, and the lower end of the top plate is a conical structure. The power supply module A1, the power switch S1, the display mechanism V, and the timing mechanism 5 are installed in the component box 8, and the component box 8 is installed at the front side end of the right measuring table 2.
[0016] Figure 1 、 2As shown, there is a spacing between the lower end of the pressure plate 42 and the inner lower end of the clamping mouth 44. The clamping mouths 44 of the fixing blocks of the two sets of fixing clamp mechanisms face each other on the inner side. When the pressure plate 42 of the fixing clamp mechanism is at the top dead center, the distance between it and the inner lower end of the clamping mouth 44 is greater than the thickness of the tape 9. The display mechanism is a liquid crystal voltage display meter V. The timing mechanism includes a variable resistor RP1, resistors R1 and R2, a triode Q1, a buzzer B, a counter A3, relays J2 and J1 connected by circuit board wiring. One end of the variable resistor RP1 is connected to one end of the first resistor R1 and one end of the second resistor R2. The other end of the second resistor R2 is connected to the base of the triode Q1. The collector of the triode Q1 is connected to the negative power input terminal of the first relay J1. The positive power input terminal and the control power input terminal of the first relay J1 and the positive power input terminal 1 of the counter A3 are connected. The normally closed contact terminal of the first relay J1 is connected to the buzzer B and the positive power input terminal of the second relay J2. The other end of the first resistor R1 is connected to the emitter of the triode Q1, the negative power input terminal of the buzzer B, the negative power input terminal of the second relay J2, and the negative power input terminal 2 of the counter A3. The two contacts of the counting button J of the counter A3 are connected to the control contact terminal and the normally open contact terminal of the second relay J2.
[0017] Figure 1 , 2 As shown, the power input terminals 1 and 2 of the power module A1 are respectively connected to the two poles of the AC 220V power supply through wires. The power output terminals 3 and 4 of the power module A1 are respectively connected to the power input terminals 1 and 2 of the power switch S1, the power input terminals 1 and 2 of the pressure sensor A2 (connected in series through the power switch S2), and the power input terminals 1 and 2 of the counter A3 of the timing mechanism through wires. The signal output terminals 3 and 2 of the pressure sensor A2 are respectively connected to the two ends of the power input of the display mechanism V through wires; the other end of the variable resistor RP1, which is the signal input terminal of the timing mechanism, is connected to the 3rd pin of the pressure sensor A2 through a wire. The power output terminals 3, 4, 5, and 6 of the power switch S1 are respectively connected to the positive and negative and negative-positive power input terminals of the electric push rod M1 through wires. The handles of the power switches S1 and S2 are located outside the openings at the front end of the component box.
[0018] Figure 1 , 2As shown, after turning on the main power switch and the 220V power supply enters the power input terminal of power module A1, the stable DC 12V power supply output from pins 3 and 4 of power module A1 enters the power input terminals of power switch S1, pressure sensor A2, and timing mechanism. Before the new type of test, the measuring personnel place the left and right sides of a section of tape 9 to be tested respectively at the lower ends of the clamping mouths of the left and right fixed clamping mechanisms and below the pressing plate 42, and then rotate the upper ends of the lead screws 43 of the two sets of fixed clamping mechanisms clockwise by hand respectively. The lead screws 43 drive the pressing plates 42 to move downward, and the two pressing plates 42 press the left and right side ends of the tape respectively. Subsequently, the test process can be entered; specifically, when the pressing plates move downward, the two lead screws rotate along the inner rings of the two bearings respectively, and the two pressing plates do not rotate, ensuring that the two pressing plates do not rotate during downward movement and facilitating the pressing of the tape (if the pressing plates rotate during downward movement, the rear side of the tape will move, and the pressing plates cannot effectively press the tape). After the subsequent test is completed, the measuring personnel rotate the upper ends of the lead screws 43 of the two sets of fixed clamping mechanisms counterclockwise by hand respectively. The lead screws 43 drive the pressing plates 42 to move upward, and the two pressing plates 42 separate from the left and right side ends of the tape respectively, and the measuring personnel can then take out the tested tape. Then the measuring personnel move the handle of power switch S1 to the left, and pins 1 and 2 of power switch S1 are connected to pins 3 and 4 respectively. The positive and negative power input terminals of the electric push rod M1 are powered on, and its push rod drives the pressure sensor and the top plate 6 to move downward. The top plate 6 gradually presses the upper part of the middle of the tape 9 downward, and the tape is gradually pressed tightly. When the electric push rod M1 drives the pressure sensor and the top plate 6 to move downward by a relatively large distance, the force acting on the force receiving surface of the pressure sensor A2 is relatively large, and the voltage signal output from its pin 3 and entering the voltmeter V is correspondingly large (the voltage signal displayed by the voltmeter V representing the downward movement distance of the top plate 6 and the pressure acting on the upper end of the tape 9 is relatively large); when the electric push rod M1 drives the pressure sensor and the top plate 6 to move downward by a relatively small distance, the force acting on the force receiving surface of the pressure sensor A2 is relatively small, and the voltage signal output from its pin 3 and entering the voltmeter V is correspondingly small (the voltage signal displayed by the voltmeter V representing the downward movement distance of the top plate 6 and the pressure acting on the upper end of the tape 9 is relatively small). Through the above, the measuring personnel can observe the voltage data displayed by the voltmeter V and set how long it takes for the top plate to break the middle of the tape under the required torque (that is, test and obtain the data on how long it takes for the tape to break under the corresponding acting force). After the top plate presses the tape 9 tightly, turn on power switch S2 and press the start timing button (momentary action type) of the timer. The timing mechanism is powered on (timer A3 is powered on and starts cumulative timing). The voltage signal output from pin 3 of the pressure sensor A2 when the top plate presses the tape tightly is divided by the adjustable resistor RP1 and resistor R1, and the voltage is reduced and the current is limited by resistor R2 and enters the base of the triode Q1 above 0.7V. The triode Q1 conducts and its collector outputs a low level and enters the negative power input terminal of the relay J1. The relay J1 is powered on and its control power input terminal and normally closed contact terminal are open, so the buzzer B and the relay J2 are not powered on, indicating that the tape has not been broken, and the counter continues to perform cumulative timing.The moment the tape 9 is broken off, the voltage signal output from pin 3 of the pressure sensor A2 (the force-receiving surface no longer receives force) stops and enters the base of the triode Q1. The triode Q1 is cut off, and the collector output stops outputting a low level and enters the negative power input terminal of the relay J1. The relay J1 loses power and no longer attracts, and its control power input terminal and normally closed contact terminal are closed. Then, both the buzzer B and the relay J2 will be powered on. After the buzzer B is powered on, it makes a sound to prompt the tester in time that the tape is broken off. The relay J2 is powered on and attracts, and its control contact terminal and normally open contact terminal are closed. The two contacts of the stop button J of the counter A3 are closed. In this way, the counter A3 stops accumulating and timing. Through the above, the tester can prompt the measurer at the moment the tape is broken off and timely turn off the stop button J of the timer A3. Subsequently, the measurer can go to the scene in time to view the time when the tape is broken off under the corresponding acting force through the time data displayed by the timer A3 (after the power switch S2 is turned off later, the timing mechanism loses power and does not measure). In actual situations, after the measurer turns on the power switch S1 to the left, the positive and negative power input terminals of the electric push rod M1 are always powered on. In this way, the electric push rod makes the top plate keep moving downward to break off the tape 9. At the moment the tape is broken off, the measurer turns off the power switch S1 (the pushing column of the electric push rod moves slowly, so it can stop moving downward in time after the power is cut off). By observing the voltage data of the voltmeter in real time (the higher the voltage data, the relatively greater the strength of the tape; conversely, the relatively smaller the strength of the tape), the measurer can timely understand the instantaneous break-off data (strength data) of the tape. Subsequently, the measurer moves the handle of the power switch S1 to the right, and the 1st, 2nd pins and 5th, 6th pins of the power switch S1 are connected respectively. The negative and positive power input terminals of the electric push rod M1 are powered on, and its pushing column drives the pressure sensor and the top plate 6 to move upward. The top plate 6 and the like return to the initial position, preparing for measuring the strength of other tapes next time.
[0019] Figure 1 、 2 As shown above, through the above, the present invention can test the instantaneous fracture data of the tape (obtain the strength data of the instantaneous fracture of the tape), and can also obtain the tape fracture time data on the basis of a certain stretching force condition (obtain the strength data of the tape on the basis of a certain acting force), providing favorable technical support for relevant personnel to accurately master the stretching force fracture data of the tape in various states (that is, obtain the strength data of the tape in various states) and ensure the product quality of the manufacturer. Figure 2Among them, the resistance values of resistors R1 and R2 are 4.7K and 10K respectively; the adjustable resistor RP1 has a specification of 10K (adjusted to 5K in this embodiment); the relays J1 and J2 are DC12V relays; the buzzer B is a finished product of an active continuous buzzer alarm of model FM12V; the liquid crystal voltage display meter V is a finished product of a 12V liquid crystal voltage display meter; the regulated power supply A1 (power supply module) is a finished product of an AC 220V to DC 12V power supply module; the electric push rod M1 is a finished product of a reciprocating electric telescopic rod with a power of 40W; the triode Q1 is of model 9013 (NPN type); the pressure sensor A2 is a finished product of a pressure sensor of model AR-DN101, which has two power input terminals and one signal output terminal. When measuring, the higher the voltage signal output by the signal output terminal under the action of the tensile force on the force-receiving surface, and vice versa (the output voltage signal is up to 10V); the timer A3 is of model SD48-T, which has two power input terminals, one stop button J, and one momentary start button. In application, it starts timing after the start button is pressed and stops timing after the stop button is pressed.
