Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper, in particular to a corrugated paper flattening device. Background Art

[0002] Before corrugated paper is put into use, it is necessary to use a flattening strength tester to test its flattening strength. Through the relative movement of the two chucks on the flattening strength tester, with the cooperation of the force sensor and the displacement sensor, the flattening strength performance of the corrugated paper can be obtained.

[0003] However, the clamp of the flattening strength tester lacks a limit mechanism for the corrugated paper. Therefore, when performing the flattening strength test, the staff needs to ensure that the position of the corrugated paper is stable to prevent the corrugated paper from falling off the clamp during the movement of the clamp. Therefore, it is necessary to improve the traditional flattening strength test device so that the corrugated paper can remain stable on the clamp by itself and cannot fall off the clamp. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems and to provide a corrugated paper flattening device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A corrugated paper flattening device comprises a body, a connecting rod, a first chuck and a second chuck, wherein an annular disk is fixed to the second chuck via a connecting piece, a sliding hole is provided on the annular disk, the sliding hole is slidably connected to a round rod fixed on an arc rod, a clamping block is fixed to the end of the round rod, a spring is provided on the round rod, a screw hole is provided on the arc rod, and a bolt is threadedly connected in the screw hole.

[0007] Preferably, the connecting member includes an annular groove on the second chuck, the annular groove fits with the annular disk, a screw groove is provided on the annular groove, a vertical hole matching the screw groove is provided on the annular disk, and the vertical hole and the screw groove are connected with a screw rod through threads.

[0008] Preferably, a notch is formed on the annular groove, and a protrusion matching the notch is fixed on the annular disk.

[0009] Preferably, three arc-shaped rods are provided, and the three arc-shaped rods form a complete collar which is slidably connected to the second chuck.

[0010] Preferably, an elastic rubber gasket protrudes from the portion where the notch engages with the protrusion.

[0011] Preferably, a rubber anti-slip ring protrudes from the portion of the clamping block that contacts the corrugated paper.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] 1. In the present application, the clamping block clamps the corrugated paper on the second chuck under the elastic force of the spring, so that the corrugated paper is fixed to the second chuck, and the corrugated paper cannot be separated from the second chuck. Therefore, when the staff conducts a flattening strength test on the corrugated paper, there is no need to pay attention to whether the corrugated paper on the second chuck will fall off the second chuck as the second chuck moves in the vertical direction.

[0014] 2. In the present application, after the protrusion is engaged with the notch, the position of the annular disk is restricted, so the annular disk cannot be rotated on the second chuck under force. At this time, the vertical hole on the annular disk is aligned with the screw groove provided on the second chuck, and the staff can more conveniently connect the screw rod with the vertical hole and the screw groove through threads, thereby fixing the annular disk and the second chuck as a whole.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1:

[0022] The utility model provides a technical solution, please refer to Figure 1-3 :

[0023] A corrugated paper flattening device comprises a body 1, a connecting rod 2, a chuck 1 3 and a chuck 2 4, characterized in that an annular disk 8 is fixed to the chuck 2 4 through a connecting piece, a sliding hole 12 is provided on the annular disk 8, the sliding hole 12 is slidably connected to a round rod 16 fixed on an arc rod 13, a clamping block 17 is fixed to the end of the round rod 16, and a rubber anti-slip ring is protruded on the part of the clamping block 17 that contacts the corrugated paper. Therefore, when the clamping block 17 presses and clamps the corrugated paper, the friction between it and the corrugated paper is effectively increased, the round rod 16 is sleeved with a spring 18, a screw hole 14 is provided on the arc rod 13, and a bolt 15 is threadedly connected in the screw hole 14. There are three arc rods 13, and the three arc rods 13 form a complete ring, which is slidably connected to the chuck 2 4. Therefore, after the three arc rods 13 are removed, the staff can remove the annular disk 8 from the chuck 2 4 by disassembling the screw rod 11.

[0024] Embodiment 2:

[0025] The technical solution is basically the same as that of the first embodiment, except that Figure 2 and Figure 3 As shown, the connecting piece includes an annular groove 5 provided on the second chuck 4, the annular groove 5 is fitted with the annular disk 8, a screw groove 7 is provided on the annular groove 5, a vertical hole 10 adapted to the screw groove 7 is provided on the annular disk 8, and a screw rod 11 is connected to the vertical hole 10 and the screw groove 7 by threads. A notch 6 is provided on the annular groove 5, and a convex block 9 adapted to the notch 6 is fixed on the annular disk 8. An elastic rubber gasket protrudes from the part where the notch 6 and the convex block 9 are engaged. After the convex block 9 is engaged with the notch 6, the vertical hole 10 is aligned with the screw groove 7, so that the staff can use the screw rod 11 to fix the annular disk 8 and the second chuck 4 as a whole.

[0026] In summary, the annular disk 8 is engaged with the annular groove 5, and the protrusion 9 is engaged with the notch 6, and the screw 11 is connected with the vertical hole 10 and the screw groove 7 by threading, and the annular disk 8 is fixed to the second chuck 4 as a whole. The three arc rods 13 are all sleeved on the lower part of the outer wall of the second chuck 4, and the end of the spring 18 is pressed to compress the spring 18 until the upper end of the spring 18 is located below the annular disk 8. After the position adjustment of the arc rod 13 is completed, the force on the spring 18 is released, and the upper end of the spring 18 is abutted against the bottom of the annular disk 8. At this time, the round rod 16 is slidably connected with the sliding hole 12.

[0027] Use bolts 15 to fix the three arc rods 13 as a whole, then the clamping block 17 can be lifted up, the spring 18 is compressed, the corrugated paper is placed on the second clamp 4, and the force on the clamping block 17 is released.
