[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0019] This utility model provides a lifting and balancing device for an inner paper cutter holder 3, the specific structure of which is as follows: like Figures 1 to 8 As shown, the lifting and balancing device includes a lifting plate 1 and a counterweight 2. The first section 111 of the lifting plate 1 is detachably connected to the inner paper knife holder 3, and the second section 121 is connected to the counterweight 2. It also includes a lifting ring 4 connected to the third section 122 of the lifting plate 1, located between the first section 111 and the second section 121. Furthermore, it includes a hook 8 connected to external lifting equipment. The lifting ring 4 is mounted on the hook 8 so that the center of gravity of the inner paper knife holder 3 and the center of gravity of the counterweight 2 are on the same horizontal plane. In a preferred embodiment, the weight of the inner paper knife holder 3 is 63 kg and it is detachably connected to the first section 111 by bolts. The counterweight 2 weighs 22 kg. To ensure that the center of gravity of the inner paper knife holder 3 and the center of gravity of the counterweight 2 are on the same horizontal plane after the lifting ring 4 is mounted, the distance from the center of gravity of the inner paper knife holder 3 to the lifting ring 4 is 272 mm, and the distance from the center of gravity of the counterweight 2 to the lifting ring 4 is 780 mm. When in use, the external lifting equipment lifts the hook 8, and the hook 8 lifts the lifting ring 4 to lift the inner paper knife frame 3. Since the center of gravity is always at the lifting ring 4, the inner paper knife frame 3 will not tilt or overturn during lifting.
[0020] like Figures 1 to 5 As shown, when lifting paper cutter holders 3 with different weights, the length of the lifting plate 1 needs to be adjusted as needed. For ease of adjustment, it is preferable that the first section 111 and the third section 122 are detachably connected. Specifically, the lifting plate 1 includes a hollow tube 12, one end of which forms the aforementioned second section 121, and the other end forms the aforementioned third section 122. The lifting plate 1 also includes a plate 11, one end of which forms the aforementioned first section 111, and the other end forms a detachable end 112 embedded in the third section 122. In use, by replacing the plate 11 with different specifications and connecting it to the tube 12, lifting plates 1 of different lengths can be formed.
[0021] Furthermore, the disassembly end 112 is provided with several disassembly holes 51, and the tube wall of the third section 122 is provided with several corresponding through hole groups. The through hole group consists of a first through hole 52 located above the disassembly holes 51 and a second through hole 53 located below the disassembly holes 51. The disassembly end 112 and the third section 122 are also connected by screws that pass through the first through hole 52, the disassembly hole 51 and the second through hole 53 in sequence. The end of the screw located outside the second through hole 53 is threadedly connected to a fixing nut, and the fixing nut abuts against the third section 122. Through the combination of embedded and screw connection, the detachable connection between the first section 111 and the third section 122 has extremely high structural strength and can meet the lifting requirements of the heavy inner lining paper knife holder 3.
[0022] like Figure 1 , Figure 6 and Figure 7As shown, to allow the counterweight 2 to be replaced according to the different weights of the inner paper knife holder 3, it is preferable that the counterweight 2 is detachably connected to the second end. Specifically, the counterweight 2 includes a counterweight part and at least one through-ring 21 disposed on the counterweight part, with the second segment 121 passing through the through-ring 21. In use, the through-ring 21 can constrain the counterweight 2 to move along its width direction, and can achieve the positioning of the counterweight very easily and quickly.
[0023] Furthermore, the counterweight is provided with a first threaded hole 61, and the second section 121 is provided with multiple second threaded holes 62. The multiple second threaded holes 62 are arranged sequentially along the length of the lifting plate 1. The counterweight and the lifting plate 1 are connected by screws that pass through the second threaded holes 62 and the first threaded holes 61 in sequence. In use, the screw connection further strengthens the connection between the counterweight 2 and the second section 121. Moreover, by selecting different second threaded holes 62, the position of the counterweight 2 can be finely adjusted to ensure precise alignment of the center of gravity.
[0024] In a preferred embodiment, there are two through-rings 21, and the first threaded hole 61 is located between the two through-rings 21 and at the midpoint of the line connecting the geometric centers of the two through-rings 21. The central arrangement of the two through-rings 21 and the screw can effectively share the shear force and ensure uniform force distribution.
[0025] like Figure 7 and Figure 8 As shown, to facilitate the adjustment of the weight of the counterweight 2, the counterweight unit includes a counterweight body 22 and multiple counterweight discs 23, which are detachably connected to the counterweight body 22. Furthermore, to prevent imbalance caused by uneven loading of the counterweight unit, it is preferable that an even number of counterweight discs 23 are symmetrically arranged on the counterweight body 22 with its central axis as the axis of symmetry. Specifically, the counterweight body 22 has an even number of third threaded holes 71, which are symmetrically arranged on both sides of the counterweight body 22 with its central axis as the axis of symmetry. A fourth threaded hole 72 is provided at the center of each counterweight disc 23. The counterweight disc 23 is connected to the counterweight body 22 by screws that pass through the fourth threaded hole 72 and the third threaded hole 71 in sequence. This centrally loaded force method effectively prevents the counterweight disc 23 from tilting.
