[0031] As Figures 1-4 shown, the film roll winding tightness detection device of the present disclosure may include components such as a ground 1, a pressing component, and a clamping component.
[0032] As Figure 1 , Figure 2 and Figure 3 shown, in the present disclosure, a film roll tube 51 is arranged inside the film roll 5. The pressing component includes a film fixing plate 6. The film fixing plate 6 is arranged at the top of the film roll 5. A tensioning rope 61 is arranged at the bottom end of the film fixing plate 6, and the other end of the tensioning rope 61 is fixedly connected to the top end of the base 15;
[0033] The clamping component includes a self-expanding sling 8. The self-expanding sling 8 is arranged inside the film roll 5. A protruding block 81 is arranged on the outer side of the self-expanding sling 8, and a tooth groove 82 is arranged on the outer side of the protruding block 81.
[0034] Thus, place the film roll 5 on the top of the base 15, set the film fixing plate 6 on the top of the film roll 5. The middle part of the film fixing plate 6 is hollowed out, so that the film fixing plate 6 can be effectively pressed on the top of the film roll 5, and the film roll tube 51 is exposed. By setting the tensioning rope 61, the tensioning rope 61 is fixed between the base 15 and the film fixing plate 6. Thus, when the upper lifting tool drives the film roll tube 51 to move upward, it can ensure that the film roll 5 does not move. By setting the self-expanding lifting tool 8, the self-expanding lifting tool 8 can be inserted into the inner side of the film roll tube 51. The outer side of the self-expanding lifting tool 8 is provided with protruding blocks 81 and tooth grooves 82. Four protruding blocks 81 are evenly arranged and slide on the inner side of the self-expanding lifting tool 8, and the ends are also limited on the inner side of the self-expanding lifting tool 8, so that the protruding blocks 81 will not slide out from the inner side of the self-expanding lifting tool 8. When not in use, the protruding blocks 81 can enter the inner side of the self-expanding lifting tool 8 as a whole for placement, can effectively contact the inner wall of the film roll tube 51, can effectively increase the friction force between the inner wall of the film roll tube 51, and when pulling upward, a greater force is generated between the protruding blocks 81 and the inner wall of the film roll tube 51, which can effectively make the self-expanding lifting tool 8 be clamped inside the film roll tube 51, facilitating the subsequent pulling work.
[0035] As Figure 3 and Figure 4 shown, in a preferred embodiment, a pull rod 83 is provided at the top of the self-expanding lifting tool 8. The pull rod 83 is slidably connected to the inner side of the self-expanding lifting tool 8. The top of the pull rod 83 is fixedly connected with a pull ring 84. A triangular extrusion block 831 is fixedly connected to the outer side of the pull rod 83. The triangular extrusion block 831 is arranged corresponding to the tooth groove 82.
[0036] Thus, by setting the pull rod 83, the pull rod 83 is slidably connected to the inner side of the self-expanding lifting tool 8. The top of the pull rod 83 is fixedly connected with a pull ring 84. A triangular extrusion block 831 is provided on the outer side of the pull rod 83. When the pull rod 83 is pulled, the pull rod 83 moves upward. At this time, the triangular extrusion block 831 also moves upward, so as to extrude the protruding block 81 from the inner side of the self-expanding lifting tool 8, and increase the extrusion of the protruding block 81 during the continuous upward movement, effectively increasing the friction force between the tooth groove 82 and the inner wall of the film roll tube 51, and improving the pulling effect.
[0037] As Figure 1 shown, in the present disclosure, a column 11 is fixedly connected to the top of the ground 1. A cross bar 12 is fixedly connected to one side of the column 11. A reinforcing rib 13 is arranged between the column 11 and the cross bar 12.
[0038] Thus, by setting the reinforcing rib 13, the firmness of the connection and fixation between the cross bar 12 and the column 11 can be effectively increased.
[0039] As Figure 1As shown, in a preferred embodiment, a hand crank 2 is fixedly connected to one side of the vertical column 11, a fixed pulley 14 and a tension sensor 4 are fixedly connected to the bottom end of the cross bar 12, a movable pulley 7 is arranged at the bottom end of the tension sensor 4, a first towing rope 3 is slidably connected to the inner sides of the fixed pulley 14 and the movable pulley 7, one end of the first towing rope 3 is in transmission connection with the hand crank 2, and the other end of the first towing rope 3 is fixedly connected to the bottom end of the tension sensor 4.
[0040] Thus, by arranging the movable pulleys 7 and 17, the first towing rope 3 slides inside them. One end of the first towing rope 3 is in transmission connection with the hand crank 2, and the other end is fixed to the bottom end of the tension sensor 4. According to the characteristics of the movable pulley 7, the tension received at the bottom end of the movable pulley 7 can be completely detected from the tension sensor 4. The tension sensor 4 can effectively detect the magnitude of the tension received at the bottom end of the movable pulley 7. By arranging the hand crank 2, the first towing rope 3 can be effectively driven to contract, and the object fixed to the bottom end of the second towing rope 71 can be effectively lifted.
[0041] As Figure 1 shown, in the present disclosure, a second towing rope 71 is fixedly connected to the bottom end of the movable pulley 7, and the bottom end of the second towing rope 71 is fixedly connected to the inner side of the pull ring 84.
[0042] Thus, the second towing rope 71 is fixed to the pull ring 84, so that the self-expanding sling 8 can be effectively lifted, that is, the membrane coil tube 51 can be effectively lifted.
[0043] During specific use, place the membrane coil 5 to be detected on the base 15, press the film fixing plate 6 against the outer edge part of the top surface of the membrane coil 5, tighten the tensioning rope 61 between the film fixing plate 6 and the base 15, place the self-expanding sling 8 into the membrane coil tube 51, and slowly lift the membrane coil tube 51 with the hand crank 2. As the membrane coil tube 51 rises, the tension will gradually increase. After reaching a certain value, the membrane coil tube 51 and the membrane coil 5 will slide and separate. This situation is called tube separation. Record the reading of the tension sensor 4 at the time of tube separation, which is the result of this test.
[0044] Those skilled in the art should understand that the above embodiments are only for clearly illustrating the present disclosure, rather than limiting the scope of the present disclosure. For those skilled in the art, other changes or variations can be made based on the above disclosure, and these changes or variations are still within the scope of the present disclosure.
