[0041] like Figures 1 to 11 As shown, an embodiment of the present invention provides a fracture strength detection device for plastic wire cloth roll production, including a machine base 1 and a tensile machine 2, the machine base 1 and the tensile machine 2 are the main bodies of the entire fracture strength detection device, the machine base 1 is used to control the tensile machine 2, so that the tensile machine 2 performs fracture strength detection on the fixed sample, and various data in the detection process are displayed on the display screen on the machine base 1, which is convenient for relevant staff to record data, the tensile machine 2 is equipped with a lifting seat 3, the bottom end of the lifting seat 3 is provided with an upper fixed seat 4, the machine base 1 is fixedly connected with a cutting seat 5 corresponding to the position of the tensile machine 2, and the top of the cutting seat 5 is provided with a flip movable The turning plate 6 is provided, and a lower fixing seat 7 is provided on one end of the cutting seat 5 close to the tensile machine 2. The cutting seat 5 and the turning plate 6 are used to process the plastic silk cloth roll into samples with consistent specifications and convenient for testing. The upper fixing seat 4 and the lower fixing seat 7 are equipped with a fixing structure for the sample to be tested for breaking strength. The structure in the upper fixing seat 4 and the lower fixing seat 7 is used to clamp and fix the top and bottom ends of the sample to be tested. After that, the tensile machine 2 can drive the upper fixing seat 4 to move through the lifting seat 3 when working, and apply a stable tensile force to the plastic silk cloth roll sample between the upper fixing seat 4 and the lower fixing seat 7, so as to detect the breaking strength of the plastic silk cloth roll sample;

[0042] The cutting assembly is used to cut the plastic wire cloth roll to be tested to form a sample for breaking strength testing. The cutting assembly is connected to the cutting seat 5 and the flip plate 6 respectively. The setting of the cutting assembly replaces the shortcomings of the traditional staff using scissors to make samples manually, so that the cut samples are consistent in size and shape, and then the subsequent test data is more accurate and more reliable. Secondly, compared with other cutting structures such as laser cutting, the cost is lower and it can be installed on the existing tensile testing machine, and the application range is wider; the ejection assembly is used The middle part of the sample after cutting on the cutting seat 5 is lifted up, and the ejection component is connected to the cutting seat 5. After the cutting component completes the production of the plastic silk cloth roll sample, the sample and the scraps of the plastic silk cloth roll are still on the cutting seat 5, and the gap is small. At this time, the ejection component can be operated to lift the middle part of the plastic silk cloth roll sample, so that there is a gap between the plastic silk cloth roll sample and the scraps and the cutting seat 5, which is convenient for the staff to take the sample, thereby making the entire plastic silk cloth roll breaking strength detection operation process smoother and easier to operate.

[0043] In this embodiment, if Figures 1 to 3 As shown, the upper fixed seat 4 is sleeved with two symmetrically distributed upper clamping jaws 9, and the upper fixed seat 4 is movably connected with a bidirectional screw 8 through a bearing, the bidirectional screw 8 is provided with two sets of threads in opposite directions, and one end of the bidirectional screw 8 extends to the outside of the upper fixed seat 4 and is fixedly connected with a rotating handle 11, the upper clamping jaws 9 and the bidirectional screw 8 are threadedly connected, and the structure provided in the upper fixed seat 4 is used for clamping and fixing the top end of the plastic silk cloth roll sample, the two upper clamping jaws 9 are symmetrically distributed on the outside of the bidirectional threads on the bidirectional screw 8, rotating the rotating handle 11 can drive the bidirectional screw 8 in the upper fixed seat 4 to rotate, and then the two upper clamping jaws 9 are synchronously pushed to slide on the inner side of the upper fixed seat 4 through the bidirectional threads on the outside of the bidirectional screw 8, changing the spacing between the two upper clamping jaws 9 until the two upper clamping jaws 9 clamp and fix the top end of the plastic silk cloth roll sample.

[0044] The position of the lower fixing seat 7 corresponds to the position of the upper fixing seat 4, and the lower fixing seat 7 is sleeved with two symmetrically distributed lower clamping jaws 12, and the lower fixing seat 7 is movably connected with a bidirectional screw 8 through a bearing, and the lower clamping jaws 12 are threadedly connected to the bidirectional screw 8. The lower fixing seat 7 and the lower clamping jaws 12 are set for clamping and fixing the bottom end of the plastic silk cloth roll sample. The lower clamping jaws 12 in the lower fixing seat 7 are also symmetrically distributed on the outside of the bidirectional threads of the bidirectional screw 8. When the bidirectional screw 8 in the lower fixing seat 7 rotates, it can also drive the lower clamping jaws 12 to slide in the lower fixing seat 7, change the spacing between the two bidirectional screws 8, and form a clamping and fixing of the bottom end of the plastic silk cloth roll sample. The position of the lower fixing seat 7 corresponds to the position of the upper fixing seat 4, and can also ensure that the plastic silk cloth roll sample after being clamped and fixed by the lower clamping jaws 12 and the upper clamping jaws 9 is in a vertical state, and is subjected to uniform force during the breaking strength test, thereby ensuring the accuracy of the test results.

[0045] In this embodiment, if Figures 5 to 8 As shown, one end of the bidirectional screw 8 in the lower fixed seat 7 extends to the interior of the machine base 1 and is fixedly connected to a transmission rod 34. The machine base 1 and the transmission rod 34 are movably connected through a bearing, and a pipe matching the size of the transmission rod 34 is opened in the machine base 1. The end of the transmission rod 34 extends to the outside of the machine base 1 and is fixedly connected to a knob 14. The arrangement of the transmission rod 34 and the knob 14 enables the staff to rotate the knob 14 at a position close to the display screen of the machine base 1, and then drives the bidirectional screw 8 in the lower fixed seat 7 to rotate through the transmission of the transmission rod 34, and finally drives the lower clamping jaw 12 to move in the lower fixed seat 7 and clamp and fix the bottom end of the plastic silk cloth roll sample. The positions of the knob 14 and the cutting seat 5 are also adapted to the regular operating habits of the staff, making the entire plastic silk cloth roll fracture strength detection process smoother to operate.

[0046] The outer parts of the upper clamping jaws 9 and the lower clamping jaws 12 are fixedly connected with positioning plates 10, and the positioning plates 10 on the two upper clamping jaws 9 and the two lower clamping jaws 12 are cross-distributed. The positioning plates 10 are provided with inclined surfaces on the surfaces facing the upper clamping jaws 9 and the lower clamping jaws 12. The arrangement of the positioning plates 10 enables the upper clamping jaws 9 or the lower clamping jaws 12 to synchronously drive the positioning plates 10 to move when they approach each other, thereby forming a space surrounding the outside of the plastic silk cloth roll sample between the upper clamping jaws 9 and the positioning plates 10 or the lower clamping jaws 12 and the positioning plates 10. The positioning plates 10 are used to block the plastic silk cloth roll sample so as to avoid the edge of the plastic silk cloth roll from deviating to the outside of the clamping area of ​​the upper clamping jaws 9 and the lower clamping jaws 12 during the clamping process, thereby helping The auxiliary positioning of the clamping operation of the plastic wire cloth roll sample is assisted by the staff to ensure that the plastic wire cloth roll sample remains in a vertical device after being clamped and fixed, and then the force is evenly applied during the subsequent fracture strength test, so that accurate and reliable test data can be obtained. The setting of the inclined surface on the positioning plate 10 makes the distance between the ends of the positioning plate 10 larger, so that the end of the plastic wire cloth roll sample can be wrapped more easily in the process of the upper clamping jaw 9 or the lower clamping jaw 12 approaching each other, and the contact between the inclined surface and the outside of the sample can push the sample to move, and guide its displacement, so as to guide the top or bottom end of the plastic wire cloth roll sample to the clamping area of ​​the upper clamping jaw 9 or the lower clamping jaw 12, so as to further ensure the accuracy of the clamping position.

[0047] In this embodiment, if Figures 3 to 5As shown, the top of the cutting seat 5 is sleeved with a uniformly distributed first telescopic column 15 and a second telescopic column 17, and the bottoms of the first telescopic column 15 and the second telescopic column 17 are fixedly connected with a damping seat 18. A second limiting groove 33 adapted to the shape of the damping seat 18 is opened in the cutting seat 5, and a spring 19 is fixedly connected between the second limiting groove 33 and the damping seat 18. The flip plate 6 is movably connected to the top of the first telescopic column 15 through a rotating rod 29. The height value of the first telescopic column 15 is greater than the height value of the second telescopic column 17, and the difference is the same as the thickness value of the flip plate 6. The flip plate 6 can flip around the rotating rod 29 above the cutting seat 5. When the flip plate 6 flips to the top of the cutting seat 5, the flip plate 6 and the cutting seat 5 are parallel to each other in this state, and the bottom surface of the flip plate 6 and the top of the cutting seat 5 are in contact with each other. Both the telescopic column 15 and the second telescopic column 17 can be telescopically slid above the cutting seat 5, and the damping seat 18 is synchronously driven to slide in the second limiting groove 33 during the sliding process. During the downward pressing of the first telescopic column 15 and the second telescopic column 17, the flip plate 6 also moves downward and approaches the top of the cutting seat 5. At this time, the spring 19 is compressed and accumulates elastic potential energy. After the external force is removed, the spring 19 can drive the first telescopic column 15 and the second telescopic column 17 to reset under the action of its own elastic force, and synchronously drive the flip plate 6 to reset. The damping seat 18 is made of hard rubber and is in close contact with the inner side wall of the second limiting groove 33. During the upward and downward sliding of the first telescopic column 15 and the second telescopic column 17, the damping seat 18 relies on the friction between the second limiting groove 33 to generate a certain resistance, thereby providing a buffer for the upward and downward sliding of the first telescopic column 15 and the second telescopic column 17.

[0048] In this embodiment, if Figures 9 to 11As shown, the cutting assembly includes a shaping groove 26 opened on the top of the cutting seat 5, a cutting sleeve 25 matched with the shape of the shaping groove 26 is fixedly connected to the flip plate 6, and a cutting knife 27 matched with the shape of the cutting sleeve 25 is fixedly connected in the shaping groove 26. The width value of the cutting knife 27 at the end is the same as the width value of the upper clamping jaw 9 and the lower clamping jaw 12. When the flip plate 6 is deflected to the top of the cutting seat 5, the cutting sleeve 25 on the flip plate 6 also corresponds to the position of the shaping groove 26 on the cutting seat 5, and then in the process of pressing the flip plate 6 down, the flip plate 6 can drive the cutting sleeve 25 to insert into the shaping groove 26, and the cutting knife 27 in the shaping groove 26 can be embedded in the inside of the cutting sleeve 25, and the plastic placed on the cutting seat 5 at this time. The silk cloth roll is cut to cut out a plastic silk cloth roll sample of the same shape as the cutting knife 27. The width value at the end of the cut plastic silk cloth roll sample is also the same as the width value of the upper clamp 9 and the lower clamp 12. The sample formed by the cutting knife 27 is wide at both ends and narrow in the middle. As a result, the clamping area of ​​the sample between the upper clamp 9 and the lower clamp 12 is wider, and the area in the middle that is mainly subjected to tensile deformation is narrower, which can guide the deformation area of ​​the sample in the process of breaking strength detection to a certain extent, and avoid the breaking of the clamping end under the action of stress and cause abnormal detection data. Then, through the cooperation of the positioning plate 10 outside the upper clamp 9 and the lower clamp 12, the plastic silk cloth roll sample can be accurately clamped to ensure the accuracy of subsequent breaking strength detection. A handle 13 is fixedly connected to the side of the flip plate 6 away from the cutting sleeve 25, and a positioning piece 30 and an anti-skid pattern 31 located outside the cutting sleeve 25 are provided on the flip plate 6. There are two positioning pieces 30, which are symmetrically distributed on both sides of the anti-skid pattern 31, and the positioning pieces 30 are adapted to the shape of the second telescopic column 17. The setting of the handle 13 can facilitate the staff to hold it. After holding the handle 13, the flip plate 6 can be flipped more easily, and the relative position between the flip plate 6 and the cutting seat 5 can be changed. When the flip plate 6 is turned, the relative position between the flip plate 6 and the cutting seat 5 can be changed. 6 is directly above the cutting seat 5, the positioning piece 30 on the flip plate 6 is sleeved on the top of the machine base 1. At this time, the flip plate 6 relies on the common support of the first telescopic column 15 and the second telescopic column 17 to maintain parallelism with the upper surface of the cutting seat 5. After that, when the flip plate 6 is pressed downward to cut the sample of the plastic silk cloth roll, the positioning piece 30 can also ensure that the flip plate 6 and the cutting sleeve 25 always maintain a parallel state with the upper surface of the cutting seat 5 during the downward movement of the flip plate 6 and the cutting sleeve 25, thereby ensuring the cutting quality of the sample.

[0049] In this embodiment, if Figures 5 to 10As shown, the ejection assembly includes a movable sheet 16 sleeved in the cutting seat 5, and a movable groove 28 adapted to the shape of the movable sheet 16 is opened in the cutting seat 5. One end of the movable sheet 16 extends to the outside of the cutting seat 5 and is provided with a pressure-bearing end 24, and the other end of the movable sheet 16 extends to the middle of the shaping groove 26 and is provided with an ejection end 22. The setting of the ejection end 22 enables the movable sheet 16 to be squeezed and slided, and the ejection end 22 can extend from the movable groove 28 and lift up the plastic silk cloth roll sample that has been cut at the shaping groove 26. A weakened area 23 is opened on the outside of the movable sheet 16, and the movable sheet 16 The outside of the movable sheet 16 is fixedly connected with the limiting sheet 32, and the movable sheet 16 is C-shaped as a whole. The setting of the weakened area 23 makes the thickness of the movable sheet 16 at the weakened area 23 thinner and the strength weaker. When the entire movable sheet 16 is subjected to external force, it can be more easily deformed in the weakened area 23, and it can also adapt to the sliding and deformation of the movable sheet 16 in the movable groove 28. A first limiting groove 21 adapted to the shape of the limiting sheet 32 ​​is provided in the cutting seat 5, and a uniformly distributed elastic sheet 20 is fixedly connected between the first limiting groove 21 and the limiting sheet 32, and the first limiting groove 21 and the movable groove 28 are connected to each other. The mutual connection between the positioning groove 21 and the movable groove 28 can ensure that the movable piece 16 will not be hindered by other obstacles during the displacement of the movable piece 16 in the movable groove 28, and is only limited by the first limiting groove 21 and the limiting piece 32. After the flip plate 6 is rotated and the flip plate 6 leaves the top of the cutting seat 5, the flip plate 6 is transferred to the top of the movable piece 16. The length of the movable piece 16 outside the cutting seat 5 in the normal state is the same as the length of the second telescopic column 17. Therefore, after the flip plate 6 is flipped 180° from the top of the cutting seat 5, it is just above the movable piece 16 and fits and contacts with the top of the pressure-receiving end 24. Then, the pressing The anti-slip groove 31 area on the flip plate 6 can squeeze the pressure end 24 on the movable sheet 16 by deflecting the flip plate 6, and then drive the movable sheet 16 to slide in the movable groove 28. After the movable sheet 16 slides in the movable groove 28, it can drive the limiting sheet 32 ​​to move downward, and at the same time compress the elastic sheet 20, and make the ejection end 22 at the end of the movable sheet 16 ejected from the middle area of ​​the shaping groove 26 on the cutting seat 5, so that a gap appears between the sample and the remaining scraps from the cutting and the upper surface of the cutting seat 5, which is convenient for the staff to take the cut samples, and further optimizes the operation steps of the entire breaking strength test.
