Description

Technical Field

[0001] This application relates to the field of packaging film tensile testing technology, specifically a packaging film tensile strength testing device. Background Technology

[0002] Packaging film is a thin film material used to wrap products. Its main function is to protect products from damage, contamination and moisture, and to extend the product's shelf life.

[0003] To measure the mechanical properties of packaging film, such as strength and elongation, during the stretching process, testing equipment is usually used to perform tensile strength tests on the packaging film. During the test, the packaging film to be tested needs to be clamped and fixed first, and then the testing equipment is started to perform the tensile test.

[0004] However, when testing batch packaging films, it is usually necessary to remove the tested packaging film first, and then install the new packaging film before testing. This results in a long time for changing packaging films, which prolongs the batch packaging film testing operation time and reduces the testing efficiency. Therefore, it is necessary to provide a packaging film tensile strength testing device to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0007] The technical solution adopted by this application to solve its technical problem is: a packaging film tensile strength testing device, comprising:

[0008] A base, on the upper end of which a tension sensor is mounted, and on the upper end of which a lower mounting plate is mounted, wherein a lower clamping component is fitted on the lower mounting plate;

[0009] A vertical plate, which is installed at the upper end of the base;

[0010] An upper mounting plate is disposed on one side of the vertical plate. An upper clamping member is mounted on the upper mounting plate. A mounting groove is formed on one side of the upper mounting plate, and engaging grooves are formed on both sides of the mounting groove.

[0011] A drive mechanism is disposed on the vertical plate, and the drive mechanism is used to drive the upper mounting plate to move;

[0012] The locking mechanism has a locking plate mounted on the upper clamping member. A gear is rotatably connected to the center end of the locking plate. Two sets of first and second horizontal frames are respectively mounted on the surface of the locking plate. A first support plate is slidably connected in the first horizontal frame, and a second support plate is slidably connected in the second horizontal frame.

[0013] Furthermore, a second rack is fixedly installed on the side of the first support plate near the gear, and the second rack is meshed with the upper part of the gear. A third rack is fixedly installed on the side of the second support plate near the gear, and the third rack is meshed with the lower part of the gear. The first support plate and the second support plate cooperate with the engaging groove.

[0014] Furthermore, two sets of vertical frames are fixedly installed vertically on the surface of the card plate, and an adjustment plate is slidably connected inside the vertical frames. The adjustment plate is located outside the second rack and the third rack. A slot is opened at the upper end of the adjustment plate, and a first rack is provided on one side of the slot.

Detailed Implementation

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] like Figures 1-2 As shown, this application provides a packaging film tensile strength testing device, including a base 1, a tensile sensor 2 fixedly installed on the upper end of the base 1, a lower mounting plate 21 fixedly installed on the upper end of the tensile sensor 2, a lower clamping member 22 assembled on the lower mounting plate 21, and the lower clamping member 22 is used to fix the packaging film to be tested from below.

[0034] Meanwhile, a vertical plate 11 is fixedly installed on the upper end of the base 1. The vertical plate 11 is located on one side of the tension sensor 2. A drive mechanism is provided on the vertical plate 11. The drive mechanism has a drive motor 18 fixedly installed on the upper end of the vertical plate 11. The drive shaft of the drive motor 18 is set downwards, and a drive rod 17 is fixedly installed on the drive shaft of the drive motor 18. A base plate 15 is threadedly connected to the drive rod 17. At the same time, two sets of slide rails 14 are fixedly installed on the inner side of the vertical plate 11. The two sets of slide rails 14 are located on both sides of the drive rod 17. Two sets of sliders 16 are also fixedly installed on one side of the base plate 15. The two sets of sliders 16 are slidably connected to the slide rails 14. Therefore, the drive motor 18 can drive the base plate 15 to perform vertical reciprocating motion. When the base plate 15 moves up and down, the sliders 16 will also slide on the slide rails 14, thus improving the stability of the base plate 15 when it moves.

[0035] Furthermore, an upper mounting plate 12 is fixedly installed on the side of the base plate 15 away from the vertical plate 11. An upper clamping member 13 is mounted on the upper mounting plate 12. The upper clamping member 13 is used to fix the packaging film to be tested above the upper clamping member 22. Therefore, the packaging film to be tested is fixed as a whole by the upper clamping member 13 and the lower clamping member 22.

[0036] In this application, the installation method and structure of the upper clamping member 13 and the lower clamping member 22 are the same. For ease of understanding, the following explanation will be based on the upper clamping member 13 as an example. Specifically:

[0037] like Figures 3-4As shown, the upper clamping member 13 has a first clamping plate 131 mounted on the upper mounting plate 12. A second clamping plate 133 is provided on the side of the first clamping plate 131 away from the upper mounting plate 12. Bolts 134 are threaded to both ends of the second clamping plate 133, and threaded holes 132 are provided at both ends of the first clamping plate 131. The bolts 134 are threaded into the threaded holes 132. Therefore, the distance between the first clamping plate 131 and the second clamping plate 133 can be adjusted by turning the bolts 134 to complete the clamping operation.

[0038] In order to quickly install the upper clamping member 13 onto the upper mounting plate 12, the upper mounting plate 12 has a mounting groove 121 on one side, and engagement grooves 122 are respectively opened on both sides of the mounting groove 121. Furthermore, an engagement mechanism 3 is provided on the side of the first clamping plate 131 away from the second clamping plate 133. The engagement mechanism 3 is fitted into the mounting groove 121.

[0039] like Figure 3 and Figures 5-6 As shown, the engaging mechanism 3 has a locking plate 31 fixedly installed on the first clamping plate 131. A gear 32 is rotatably connected to the center end of the locking plate 31. Two sets of first horizontal frames 311 and second horizontal frames 312 are fixedly installed laterally on the surface of the locking plate 31. A first support plate 33 is slidably connected in the first horizontal frame 311. A second rack 331 is fixedly installed on the side of the first support plate 33 near the gear 32. The second rack 331 is meshed with the upper part of the gear 32. A second support plate 39 is slidably connected in the second horizontal frame 312. A third rack 391 is fixedly installed on the side of the second support plate 39 near the gear 32. The third rack 391 is meshed with the lower part of the gear 32. In this application, the first support plate 33 and the second support plate 39 cooperate with the engaging groove 122. Therefore, rotating the gear 32 can drive the first support plate 33 to move laterally through the second rack 331 and drive the second support plate 39 to move laterally through the third rack 391.

[0040] Meanwhile, two sets of vertical frames 313 are vertically fixedly installed on the surface of the card plate 31. An adjusting plate 34 is slidably connected inside the vertical frame 313. The adjusting plate 34 is located outside the second rack 331 and the third rack 391. A slot 341 is opened at the upper end of the adjusting plate 34. A first rack 342 is provided on one side of the slot 341. The first rack 342 is meshed with one side of the gear 32. At the same time, a handle 35 is fixedly installed at the lower end of the adjusting plate 34. Therefore, the adjusting plate 34 can be easily pulled up and down through the handle 35. When the adjusting plate 34 moves up and down, it will drive the gear 32 to rotate through the first rack 342. The rotation of the gear 32 will drive the first support plate 33 and the second support plate 39 to move.

[0041] To ensure the stability of the first support plate 33 and the second support plate 39 protruding outwards, two sets of baffles 36 are fixedly installed at the bottom of the clamping plate 31. The two sets of baffles 36 are located inside the vertical frame 313. At the same time, two sets of placement slots 38 are opened on the adjusting plate 34. The baffles 36 are located in the placement slots 38. A compression spring 37 is fixedly installed between the inner sides of the baffles 36 and the placement slots 38. Therefore, in the initial state, the first support plate 33 and the second support plate 39 protrude outwards.

[0042] Meanwhile, a vertical groove 343 is provided on the adjusting plate 34, which is located between the two sets of placement grooves 38. At the same time, a column 314 is fixedly installed on the clamping plate 31, which is located between the compression springs 37. In this application, the column 314 is slidably connected in the vertical groove 343. Therefore, when the adjusting plate 34 slides, the column 314 and the vertical groove 343 limit the sliding of the adjusting plate 34 to be more stable.

[0043] In this application, at least two sets of the upper clamping member 13 and the lower clamping member 22 are provided to facilitate replacement.

[0044] In summary: When testing the packaging film, it is first fixed between the upper clamp 13 and the lower clamp 22, and then the drive motor 18 is started to move the upper clamp 13 upward, thus completing the tensile strength test of the packaging film.

[0045] During the testing of a set of packaging films, the operator installs the next set of packaging films between the upper clamp 13 and the lower clamp 22 of the second set. After the test is completed, the operator manually pulls the handle 35 in the locking mechanism 3 on the upper clamp 13 and the lower clamp 22 outward, so that the first support plate 33 and the second support plate 39 are retracted, and the upper clamp 13 and the lower clamp 22 are removed as a whole with the packaging film. Then, the prepared second set of upper clamp 13 and lower clamp 22 are installed into the upper mounting plate 12 and the lower mounting plate 21 in the same way, and then the tensile test is continued.

[0046] At this point, the packaging film in the upper clamp 13 and lower clamp 22 that were removed is disassembled and replaced, which speeds up the time for changing the packaging film, shortens the batch packaging film testing operation time, and improves the testing efficiency.

[0047] It should be noted that the lower mounting plate 21 also has a slot that matches the locking mechanism 3.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
