[0024] Please see Figures 1-2In this embodiment of the utility model, a paper bowl edge strength testing device includes a test placement device 1. The upper end of the test placement device 1 is provided with a paper bowl body 2. A counterweight water tank 3 is provided above the paper bowl body 2. A connecting block 40 is provided at the bottom inner side of the paper bowl body 2. A hanging rope 4 is connected to the connecting block 40. There are four hanging ropes 4, which are arranged in a circular array. The counterweight water tank 3 is placed on the connecting block 40 at the bottom inner side of the paper bowl body 2. The ends of the four hanging ropes away from the connecting block 40 are attached to the edge of the paper bowl body 2, and a counterweight block 401 is fixedly installed at the ends of the four hanging ropes away from the connecting block 40. A box cover 5 is fixedly connected to the upper end of the counterweight water tank 3. A water inlet pipe 6 is fixedly installed on one side of the upper end of the box cover 5. A water outlet pipe 7 is fixedly installed at the lower end of one side wall of the counterweight water tank 3. A control valve 8 is provided on both the water inlet pipe 6 and the water outlet pipe 7. The counterweight water tank 3 restricts the position of the connecting block 40 placed at the bottom of the inner side of the paper bowl body 2. The edge strength of the paper bowl body 2 can be tested by the cooperation of the connecting block 40, the hanging rope 4, and the counterweight 401. This method is not only simple and convenient to operate, but also has low production cost, and can be widely used in small production enterprises and indoor laboratories.

[0025] In order to make the amount of water added in the counterweight water tank 3 observable, an observation port 9 is provided on one side wall of the counterweight water tank 3. A transparent glass is fixedly installed in the observation port 9. A scale line 10 is provided on one side wall of the counterweight water tank 3. The scale line 10 is located on one side of the observation port 9. The setting of the observation port 9 and the scale line 10 makes it easy to observe the amount of water added to the counterweight water tank 3.

[0026] The test placement device 1 includes a placement base plate 101. The paper bowl body 2 is seated in the middle of the upper end surface of the placement base plate 101. Support legs 102 are fixedly installed on the lower end surface of the placement base plate 101. There are four support legs 102, which are located at the four corners of the lower end surface of the placement base plate 101. Each support leg 102 has an insertion port 103 on its lower end surface. Each support leg 102 has a support block 104 below it. An insertion rod 105 is fixedly installed on the upper end surface of the support block 104. The four insertion rods 105 are respectively inserted into the insertion ports 103 on the lower end surfaces of the four support legs 102. The placement base plate 101 supports the paper bowl body 2, and the support legs 102 support the placement base plate 101.

[0027] In order to allow the height of the base plate 101 to be adjusted, such as Figure 3As shown, each of the support legs 102 has a first positioning hole at the lower end of one side wall, and each of the insert rods 105 has a plurality of second positioning holes in sequence on one side wall. Each of the first positioning holes is provided with a positioning bolt 106. One end of each positioning bolt 106 passes through the first positioning hole and into a second positioning hole on one side wall of the insert rod 105. When it is necessary to adjust the height of the base plate 101, loosen the positioning bolt 106, and then move the support block 104 up and down along the insertion port 103. When the support block 104 moves to the appropriate position, insert the positioning bolt 106 through the first positioning hole into a second positioning hole on one side wall of the insert rod 105. This design facilitates the adjustment of the height of the base plate 101.

[0028] To prevent the test placement device 1 from tilting due to uneven ground during use, such as Figure 4 As shown, each support block 104 has a threaded opening on its lower end face, and each support block 104 has a pad 107 below it. Each pad 107 has a threaded rod 108 fixedly installed on its upper end face. The four threaded rods 108 correspond to the positions of the four threaded openings, and the four threaded rods 108 are connected to the four threaded openings by threads. When the test placement device 1 is placed on an uneven ground, the pad 107 is rotated. The rotation of the pad 107 causes the threaded rods 108 to rotate within the threaded openings. The rotation of the threaded rods 108 finely adjusts the height of the support leg 102 until the test placement device 1 is adjusted to be level. This can prevent the device from tilting due to uneven ground during use.

[0029] The working principle of this utility model is as follows:

[0030] First, place the paper bowl body 2 in the middle of the upper surface of the base plate 101. Then, place the connecting block 40 on the bottom inner side of the paper bowl body 2 and press the counterweight water tank 3 containing a certain weight of water onto the upper surface of the connecting block 40. Next, hang the counterweight block 401 connected to the hanging rope 4 on the connecting block 40 on the edge of the paper bowl body 2. Hang it for five seconds. If the paper bowl body 2 breaks, the product is unqualified. If the paper bowl body 2 does not break, the product is qualified.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
