[0002] Food storage bags, mainly made of food preservation film, are bags used to preserve vegetables, fruits, grains, cooked food and other foods. They are widely used in daily life. When producing food storage bags, in order to ensure the quality and strength of the connection between the bags, a tensile test is required. This requires the use of a food storage bag sealing tensile strength testing device.

[0003] The tensile strength testing devices for sealing edges of food storage bags currently on the market have the following problems in actual use:

[0004] 1. Traditional food storage bag sealing tensile strength testing devices have poor protection because the test position is exposed to the outside during testing. When the food storage bag breaks during the test, the broken part of the bag will pull outwards.

[0005] 2. Most food storage bag sealing tensile strength testing devices are inconvenient to use because they do not have a horizontal testing device. When the device is tilted after placement, the stress point of the device will change, which may affect the test value. Utility Model Content

[0029] like Figure 1-5As shown, the present invention provides a tensile strength testing device for sealing edges of food storage bags, comprising a testing device body 1, a base 2 mounted at the bottom of the testing device body 1, a fixing block 4 welded to the top of the testing device body 1, a bushing 5 welded to the top of the fixing block 4, a shaft 6 sleeved inside the bushing 5, a fixing frame 7 welded to the surface of the shaft 6, a protective plate 3 welded to the other end of the fixing frame 7, and glass 8 adhered to the surface of the protective plate 3. The protective plates 3 are symmetrically distributed. By installing the protective plates 3, when using the device, the bushing 5 and the shaft 6 can be used to rotate the protective plates 3 until the protective plates 3 are fully extended. The testing device body 1 is concealed inside. The protective plate 3 can be used to block the food storage bag being tested inside the device, preventing it from being pulled out. The operation inside the device can be observed through the glass 8. It has strong protective properties during use. The shaft 6 has external threads on its surface, and the extrusion turntable 9 is fitted onto the surface of the shaft 6. When it is necessary to fix the position of the protective plate 3 by installing the extrusion turntable 9, the external threads on the surface of the shaft 6 can be used as a basis. By rotating the extrusion turntable 9, the friction between the bushing 5 and the fixing frame 7 is increased, thereby fixing the baffle. It is very convenient to use.

[0030] A second external threaded rod 22 is welded to the bottom of the base 2. An internal threaded sleeve 21 is fitted onto the surface of the second external threaded rod 22. A base plate 20 is welded to the bottom of the internal threaded sleeve 21. A retaining strip 15 is installed at the bottom of the base 2. A sliding groove 16 is opened on the surface of the retaining strip 15. A slider 17 is engaged inside the retaining strip 15. A sliding rod 18 is welded to the bottom of the slider 17. The sliding rod 18 is located inside the sliding groove 16. A movable plate 14 is welded to the side of the slider 17. A level 10 is glued to the top of the movable plate 14. By installing the level 10, the internal threaded sleeve 21, and the second external threaded rod 22, the level effect of the device after placement can be observed using the level 10. If the device is not level, the internal threaded sleeve 21 can be rotated to provide movement to the floor, thereby adjusting the device. It is very convenient to use.

[0031] The base 2 has a first external threaded rod 13 welded to its bottom, and a fixing plate 11 welded to the side of the clip 15. The first external threaded rod 13 passes through the fixing plate 11, and a nut 12 is fitted onto the surface of the first external threaded rod 13. One end of the nut 12 is attached to the bottom of the fixing plate 11. By installing the first external threaded rod 13, when the clip 15 needs to be installed, the first external threaded rod 13 can pass through the fixing plate 11, and then the nut 12 is fitted onto the surface of the first external threaded rod 13 until one end of the nut 12 is attached to the bottom of the fixing plate 11. At this time, the clip 15 can be installed, ensuring the stability of the clip 15 during use.

[0032] The protective plate 3 is fixedly connected to the fixing seat 25, which is symmetrically distributed. The other end of the fixing seat 25 is fixedly connected to the handle 26. By installing the handle 26, when it is necessary to rotate the protective plate 3, the handle 26 can be used as the force point, and the protective plate 3 can be directly driven to rotate through the handle 26, which is very convenient to use.

[0033] A baffle 19 is welded to the other end of the slide bar 18. The baffles 19 are symmetrically distributed. By installing the baffles 19, the baffles 19 can provide a limiting effect for the slide bar 18, so that the slide bar 18 will not fall out of the slide groove 16, which is very convenient to use.

[0034] A collar 24 is fitted onto the surface of the base plate 20. An anti-slip pad 23 is bonded inside the collar 24. The top of the anti-slip pad 23 is attached to the bottom of the base plate 20. By installing the anti-slip pad 23, the friction between the base plate 20 and the placement position can be increased, thereby improving the stability of the device after placement.

[0035] The working principle of this food storage bag sealing tensile strength testing device is as follows: When using this device, the clip 15 should be installed first. During installation, the first external threaded rod 13 can be used to penetrate the fixing plate 11. Then, a nut 12 is fitted onto the surface of the first external threaded rod 13 until one end of the nut 12 is attached to the bottom of the fixing plate 11. This provides the installation effect for the clip 15. The device can then be placed in a suitable position. At this point, a second external threaded rod 22 is welded to the bottom of the base 2, and the surface of the second external threaded rod 22...

A slider 17 is fitted inside the retaining strip 15, and a sliding rod 18 is welded to the bottom of the slider 17. At this time, the sliding rod 18 is located inside the groove 16. A movable plate 14 is welded to the side of the slider 17, and a level 10 is attached to the top of the movable plate 14. When the device is placed, the groove 16 can be used to move the sliding rod 18, thereby moving the movable plate 14 out of the base 2. Then, the level effect of the device after placement can be observed using the level 10. If it is not level, the internal threaded sleeve 21 can be rotated to provide movement to the floor, thereby adjusting the device. It is very convenient to use. After that, the device can be used. When using the device, the base 2 is installed at the bottom of the test device body 1, and the fixing block 4 is welded to the top of the test device body 1. The bushing 5 is welded to the top of the fixing block 4. The shaft 6 is sleeved inside the bushing 5, and the fixing frame 7 is welded to the surface of the shaft 6. The other end of the fixing frame 7 is welded to the protective plate 3, and the glass 8 is glued to the surface of the protective plate 3. At this time, the protective plate 3 is symmetrically distributed. The shaft 6 has external threads, and the extrusion turntable 9 is sleeved on the surface of the shaft 6. The bushing 5 and the shaft 6 can be used to rotate the protective plate 3 until the protective plate 3 hides the inside of the test device body 1. At this time, the protective plate 3 can be used to block the food storage bag being tested inside the device, so that it cannot be pulled out. The operation inside the device can be observed through the glass 8. It has strong protection when used.
