[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0032] Refer to Figure 1 、Figure 2 and Figure 3 An embodiment provided by the present utility model: A fixture device for cover glue peeling test, including a base 1 providing support. A clamping assembly is provided at the top of the base 1. The clamping assembly includes a fixture two 3 for fixing the left and right sides of the wet wipe flip cover and a fixture one 2 for fixing the front and back sides of the wet wipe flip cover. A positioning block 4 providing support and guidance is provided on the front surface of the fixture two 3. A guide rod 33 driving the positioning block 4 to move is fixedly connected to the bottom end of the positioning block 4. An activity groove 31 for the linear movement of the guide rod 33 is opened at the top of the base 1. The guide rod 33 is slidably connected to the inner wall of the activity groove 31. A turntable 34 is rotatably connected to the inner wall of the base 1 near the lower part of the activity groove 31, which drives the guide groove 35 to rotate and squeeze the guide rod 33 so that a plurality of guide rods 33 can move inward to clamp the wet wipe flip cover. A guide groove 35 for pushing the guide rod 33 to move the guide rod 33 is opened at the top of the turntable 34. The guide rod 33 is slidably connected to the inner wall of the guide groove 35.
[0033] Referring to Figure 1 、 Figure 2 and Figure 4 ,An adjusting assembly is provided on the rear surface of the positioning block 4. The adjusting assembly includes a support plate 42 providing support and guidance to drive the fixture two 3 and the fixture one 2 to move. The support plate 42 penetrates and is slidably connected to the front surface of the positioning block 4. A positioning groove 41 for limiting the direction of moving the fixture two 3 outward by sliding the limiting rod 43 into the positioning groove 41 is opened at the top of the support plate 42, and a plurality of groups are opened. A plurality of groups of positioning grooves 41 are all opened at the top of the support plate 42. By providing a plurality of groups, the positions of the fixture one 2 and the fixture two 3 relative to each other can be adjusted according to the size of the wet wipe flip cover, improving the applicability.
[0034] Referring to Figure 2 、 Figure 3 and Figure 5 ,The guide groove 35 is set in an arc shape. By setting the guide groove 35 in an arc shape, the guide rod 33 can be squeezed by the arc-shaped surface so that the guide rod 33 can move inward to drive the positioning block 4 and the fixture two 3 to move inward to fix the wet wipe flip cover. A positioning rod 37 for supporting the turntable 34 and driving the turntable 34 to rotate is fixedly connected to the center of the bottom end of the guide groove 35. The positioning rod 37 is rotatably connected to the inner wall of the base 1 below the turntable 34. A worm gear 38 for driving the positioning rod 37 and the turntable 34 to rotate is fixedly connected to the outer wall of the positioning rod 37 near the lower part of the turntable 34.
[0035] Furthermore, a rotating rod 32 is rotatably connected to the front surface of the base 1 to drive the worm 36 to rotate. A worm 36 is fixedly connected to the rear surface of the rotating rod 32 to drive the worm wheel 38 to rotate. The worm 36 meshes on the right side of the worm wheel 38. By the meshing of the worm 36 and the worm wheel 38, the worm 36 can drive the worm wheel 38 to rotate, while the worm wheel 38 cannot drive the worm 36 to rotate, so as to achieve a limiting effect. Multiple groups of positioning blocks 4, guide rods 33, and guide grooves 35 are provided. The multiple groups of positioning blocks 4, guide rods 33, and guide grooves 35 are symmetrically arranged with the center line of the base 1 as the axis of symmetry. The fixture one 2 is arranged on the left side of another group of positioning blocks 4 on the right side. Setting multiple groups can fix the four sides of the wet wipe flip cover at the same time, improving the fixing effect and stability.
[0036] Refer to Figure 1 、 Figure 2 and Figure 4 As shown in, a limiting rod 43 is slidably connected to the top end of the positioning block 4. The limiting rod 43 can slide into the positioning groove 41 to limit the fixture two 3 in the outward direction. A support spring 44 for driving the limiting rod 43 to reset is fixedly connected to the outer wall of the limiting rod 43. The support plate 45 is elastically connected to the positioning block 4 through the spring 44. One end of the spring 44 is fixedly connected to the top end of the support plate 45, and the other end of the spring 44 is fixedly connected to the inner wall of the top end of the positioning block 4. The spring 44 is sleeved on the outer wall of the limiting rod 43. By pulling the limiting rod 43 outward to drive the support plate 45 to move and compress the spring 44, the reverse acting force of the compressed spring 44 can drive the limiting rod 43 to reset, so as to facilitate the inward adjustment of the fixture two 3 and improve the operation convenience.
[0037] Furthermore, the support plate 45 is slidably connected to the inner wall of the positioning block 4. The front surface of the bottom end of the limiting rod 43 is set as an inclined surface. When the fixture two 3 and the support plate 42 are moved inward, the inclined surface of the limiting rod 43 is squeezed, so that the limiting rod 43 moves outward to compress the spring 44. Thus, the reverse acting force of the compressed spring 44 can drive the limiting rod 43 to reset and slide into the positioning groove 41 to limit the outward movement direction of the support plate 42, improving the adjustment convenience. The bottom end of the limiting rod 43 slides on the inner wall of the positioning groove 41. Multiple groups of support plates 42 and limiting rods 43 are provided, and the multiple groups of support plates 42 and limiting rods 43 are symmetrically arranged with the center line of the base 1 as the axis of symmetry. The fixture two 3 is fixedly connected to the rear surface of the support plate 42, and the fixture one 2 is fixedly connected to the left side of another group of support plates 42 on the right side. Setting multiple groups can cooperate with the support to adjust multiple groups of fixture two 3 and fixture one 2, so as to fix wet wipe flip covers of different sizes.
[0038] Working principle: When in use, during the glue covering peeling test, first adjust the positions of fixture 1 and fixture 2 according to the size of the wet wipe flip cover. By pulling the limit rod 43 outwards, drive the support plate 45 to move and compress the spring 44. At this time, fixture 2 and the support plate 42 can be moved. When moving fixture 2 and the support plate 42 inwards, the inclined surface of the limit rod 43 will be squeezed, causing the limit rod 43 to move outwards and compress the spring 44. When fixture 2 and the support plate 42 move to the appropriate positions, the reverse acting force of the compressed spring 44 drives the limit rod 43 to reset and slide into the corresponding positioning groove 41, thereby limiting the direction of the outward movement of the support plate 42 and realizing the adjustment of the distance between fixture 1 and fixture 2 to adapt to wet wipe flip covers of different sizes.
[0039] Then rotate the rotating rod 32 to drive the worm 36 on its rear surface to rotate. Through the meshing of the worm 36 and the worm wheel 38, drive the worm wheel 38, the positioning rod 37, and the turntable 34 to rotate. Since the guiding groove 35 at the top of the turntable 34 is arc-shaped, when the turntable 34 rotates, the arc-shaped guiding groove 35 surface will squeeze the guiding rod 33 to move inwards. Through multiple groups of guiding rods 33 sliding linearly inwards along the inner wall of the movable groove 31, thereby driving the positioning block 4, fixture 2, and fixture 1 to move inwards. Through the cooperative movement of fixture 2 and fixture 1, the four sides of the wet wipe flip cover are fixed simultaneously, improving the fixing effect and stability.
[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
