Description

Technical Field

[0001] The utility model relates to the technical field of strapping belt detection, in particular to a strapping belt toughness detection device. Background Art

[0002] The strapping tape (binding tape) for packaging is made of polyethylene, polypropylene resin, cold-rolled steel strip as the main raw materials, and also made of nylon and polyester as raw materials. It is made by extrusion, uniaxial stretching, and heat treatment and bluing. In addition to being used for sealing and bundling corrugated boxes, bundling hot-rolled steel coils, and bundling cold-rolled steel coils, it can also be used to bundle glass, pipes, materials, fruits, etc.

[0003] Toughness testing is one of the testing items for strapping tapes. Currently, the toughness testing of strapping tapes is mostly done by load-bearing methods. This method not only requires the preparation of more counterweights, but also requires more personnel assistance, which is more troublesome to operate. Although some devices that use the strapping tape to be pulled and stretched for testing have appeared, the testing device is large in size and poor in portability because the strapping tape to be tested has a certain length. At the same time, it is not easy to tighten the strapping tape before it is fixed, which can easily affect the elongation distance during testing and reduce the accuracy of the test. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a strapping belt toughness detection device, which solves the problems that the existing strapping belt detection devices are large in size and poor in portability, and the strapping belt is not easy to tighten before being fixed, which easily affects the elongation distance during detection and reduces the detection accuracy.

[0006] (II) Technical solution

[0007] To achieve the above purpose, the utility model is implemented by the following technical solutions: a strapping toughness detection device, including a frame and a fixing plate fixed inside the frame, a pressure sensor is provided on the top of the fixing plate, a strapping fixing assembly corresponding to the pressure sensor is provided in the frame, a tension spring and a distance measuring rod corresponding to the strapping fixing assembly are provided on the top of the inner wall of the frame, a lifting ring for the strapping to pass through is connected to the bottom of the tension spring, a sliding plate slidably connected to the frame is provided above the fixing plate, a lifting piece is connected to the sliding plate and the bottom of the inner wall of the frame, and the lifting piece is a mechanical jack or a hydraulic jack;

[0008] The strapping belt fixing assembly includes a fixed pulley located on the frame and the fixed plate, an upper and lower sleeve frame on the fixed plate, a fixed frame at the bottom of the sliding plate, and clamping members in the upper and lower sleeve frames and the fixed frame. The fixed plate, the sliding plate, the upper and lower sleeve frames and the fixed frame are all provided with channels for the strapping belt to pass through.

[0009] Furthermore, there are three groups of strapping tape fixing components, which are arranged corresponding to the pressure sensor and the tension spring. The three groups of strapping tape fixing components enable three strapping tapes to be detected in a single operation, which is beneficial to improving the detection efficiency.

[0010] Furthermore, a through hole is opened in the fixed plate for the upper and lower frames to pass through, and the upper and lower frames can produce longitudinal relative displacement with the fixed plate through the through hole. The pressure sensor is located in the upper and lower frames. During detection, the strapping belt drives the upper and lower frames to move downward, thereby pressing down the pressure sensor, and measuring and displaying the tension on the strapping belt.

[0011] Furthermore, the pressure sensor is a digital display rechargeable sensor.

[0012] Furthermore, the ranging rod is located directly below the fixed frame, passes through the fixed plate and is in sliding contact with the fixed plate. The ranging rod is made of a magnetic material with scale lines on the outside and can be attracted to the fixed frame made of iron. A screw that contacts the ranging rod passes through the front surface of the fixed plate. The screw does not contact the ranging rod before measurement. When the fixed frame rises, the ranging rod can rise together. When the strapping tape at this location shows signs of breaking, the screw can be rotated to contact the ranging rod to limit its movement, thereby stabilizing the moving length trace of the strapping tape and facilitating subsequent calculations.

[0013] Furthermore, the fixed pulleys are staggered at the bottom of the inner wall of the frame and the bottom of the fixed plate.

[0014] (III) Beneficial effects

[0015] The utility model provides a packing belt toughness detection device, which has the following beneficial effects:

[0016] 1. The strapping belt toughness detection device, through the staggered fixed pulleys, makes the strapping belt go around during detection, which ensures the detection length while greatly reducing the volume of the detection device, which is conducive to improving the portability of the device; before the detection, the strapping belt is passed through the ring under the tension spring, and the strapping belt to be detected is straightened through the elastic deformation of the tension spring to prevent the strapping belt from being loose when fixed, which affects the accuracy of the elongation length detection.

[0017] 2. The strapping belt toughness detection device uses three sets of strapping belt fixing components to enable a single operation to detect three strapping belts, which is beneficial to improving the detection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a strapping toughness detection device, such as Figure 1-3 As shown, it includes a frame 1 and a fixed plate 2 fixed therein, a pressure sensor 6 is provided on the top of the fixed plate 2, a strapping tape fixing assembly corresponding to the pressure sensor 6 is provided in the frame 1, a tension spring 10 and a distance measuring rod 11 corresponding to the strapping tape fixing assembly are provided on the top of the inner wall of the frame 1, a lifting ring for the strapping tape to pass through is connected to the bottom of the tension spring 10, a sliding plate 3 slidably connected to the frame 1 is provided above the fixed plate 2, and a lifting member 4 is connected to the sliding plate 3 and the bottom of the inner wall of the frame 1, and the lifting member 4 is a mechanical jack or a hydraulic jack, and the strapping tape is made to be looped during detection through staggered fixed pulleys 5, which ensures the detection length while greatly reducing the volume of the detection device, which is conducive to improving the portability of the device; before detection, the strapping tape is passed through the lifting ring below the tension spring 10, and the strapping tape to be detected is straightened through the elastic deformation of the tension spring 10 to prevent the strapping tape from being loose when fixed, which affects the accuracy of the elongation length detection;

[0024] The strapping tape fixing assembly includes a fixed pulley 5 located on the frame 1 and the fixed plate 2, an upper and lower sleeve frame 7 on the fixed plate 2, a fixed frame 8 at the bottom of the sliding plate 3, and a clamping piece 9 in the upper and lower sleeve frame 7 and the fixed frame 8. The clamping piece 9 is composed of two clamping blocks and a push rod. One clamping block is fixed on the upper and lower sleeve frame 7 or the fixed frame 8, and the other clamping block is slidably connected to the upper and lower sleeve frame 7 or the fixed frame 8. The push rod is rotatably connected to the clamping block and penetrates the upper and lower sleeve frame 7 or the fixed frame 8 and is threadedly connected thereto. Channels for the strapping tape to pass through are provided on the fixed plate 2, the sliding plate 3, the upper and lower sleeve frame 7 and the fixed frame 8. The channels on the fixed plate 2 and the sliding plate 3 are on the same vertical line, and the channels will not affect the detection of the strapping tape.

[0025] Specifically, there are three groups of strapping tape fixing components, which are arranged corresponding to the pressure sensor 6 and the tension spring 10. The three groups of strapping tape fixing components enable a single operation to detect three strapping tapes, which is beneficial to improving the detection efficiency.

[0026] Specifically, a through hole is opened in the fixed plate 2 for the upper and lower frames 7 to pass through. The upper and lower frames 7 can produce longitudinal relative displacement with the fixed plate 2 through the through hole. The pressure sensor 6 is located in the upper and lower frames 7. During detection, the strapping belt drives the upper and lower frames 7 to move downward, thereby pressing down the pressure sensor 6, and measuring and displaying the maximum tension on the strapping belt.

[0027] Specifically, the pressure sensor 6 is a digital display rechargeable sensor.

[0028] Specifically, the ranging rod 11 is located directly below the fixed frame 8, and passes through the fixed plate 2 and is in sliding contact with it. The ranging rod 11 is made of a magnetic material with scale lines on the outside, and can be attracted to the fixed frame 8 made of iron. A screw that contacts the ranging rod 11 passes through the front surface of the fixed plate 2. The screw does not contact the ranging rod 11 before measurement. When the fixed frame 8 rises, the ranging rod 11 can rise together. When the strapping tape at this location shows signs of breaking, rotating the screw to contact the ranging rod 11 can limit its movement, thereby stabilizing the moving length trace of the strapping tape and facilitating subsequent calculations.

[0029] Specifically, the fixed pulleys 5 are staggeredly arranged at the bottom of the inner wall of the frame 1 and the bottom of the fixed plate 2 .

[0030] Working principle: When in use, first fix one end of the strapping tape on the clamping piece 9 on the upper and lower sleeve frames 7, and the other end passes through the fixed pulley 5 in turn, passes through the fixed plate 2, the fixed frame 8, the clamping piece 9 and the sliding plate 3, and finally passes through the lifting ring to pull down the strapping tape. After the tension spring 10 is deformed and stabilized, one hand stabilizes the strapping tape and the other hand controls the clamping piece 9 to clamp the other end of the strapping tape to complete the installation of the strapping tape. After all the strapping tapes on the equipment are installed, the sliding plate 3 is controlled to rise slowly by the lifting piece 4, and the fracture of the strapping tape is observed at the same time. The distance measuring rod 11 at the strapping tapes that have been broken one after another is positioned in turn. The final statistical data can be used to know whether the elongation degree and tensile strength of the strapping tape meet the toughness index.
