[0002] With social development and the increasing variety of goods, people are paying more and more attention to the outer packaging of goods. Corrugated paper is one of the important materials for outer packaging of goods, so the demand for corrugated paper is increasing day by day. In order to better cater to consumers, corrugated paper manufacturers are also setting up factories like mushrooms after rain.

[0003] Currently, corrugated rolls are used in corrugated paper production lines. These rolls effectively control the moisture content of the corrugated paper, thus controlling the finishing effect. Therefore, corrugated rolls play a crucial role in the corrugated paper production line. However, the production process requires welding of these rolls. Because of their large size, laying the rolls flat during welding at both ends would negatively impact the welding results. Therefore, the rolls must be vertically clamped, requiring workers to climb to a high position for welding. This is inconvenient, affecting welding efficiency and posing certain safety hazards.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0030] Please see Figure 1 As shown, this utility model provides a welding fixture for corrugated roll production, comprising: a chamber 1 extending downwards from the production workshop floor; a standing platform 2 at the top of the chamber 1; a clamping hole 21 on the standing platform 2; a locking member 3 on one side of the clamping hole 21; a support frame inside the chamber 1, located directly below the clamping hole 21; and a limiting member 4 at the top of the support frame, the limiting member 4 being funnel-shaped. The locking member 3 and the limiting member 4 are used to limit the two ends of the corrugated roll, respectively. In this embodiment, the standing platform 2, the support frame, and the limiting member 4 are all made of metal to provide sufficient strength and rigidity to support the worker and clamp the corrugated roll; there are at least two supports, limiting members 4, and clamping holes 21, and the two supports have different heights to clamp corrugated rolls of different lengths; the limiting member 4 is funnel-shaped, and corrugated rolls of different diameters will abut against different positions within the limiting member 4 during clamping, thus enabling the welding fixture to be applicable to corrugated rolls of different diameters.

[0031] In the welding process, the corrugated roll to be welded is vertically placed into the chamber 1 through the clamping hole 21, with the lower end of the corrugated roll confined within the limiting member 4, and the upper end protruding from the clamping hole 21 and locked in place by the locking member 3. Workers can then stand on the standing platform 2 to perform the welding. This welding fixture for corrugated roll production utilizes a chamber 1 located below ground level and a support frame within the chamber 1 to hold the corrugated roll. The limiting member 4 and the locking member 3 clamp and secure the corrugated roll, facilitating clamping. Workers do not need to climb to higher ground; they can perform welding operations simply by standing on the standing platform 2, reducing the risk to workers and improving the safety of both the corrugated roll and the workers.

[0032] Please see Figure 1As shown, the support includes a first frame 5 and a second frame 6. The first frame 5 and the second frame 6 have the same structure, but the volume of the first frame 5 is larger than that of the second frame 6. The first frame 5 is fitted over the second frame 6. The first frame 5 includes three support rods 51 and at least two triangular frames 52. The three support rods 51 are fixedly connected to the three corners of the triangular frames 52, and the at least two triangular frames 52 are fixedly connected via the support rods 51 and are parallel to each other. In this embodiment, the triangular frames 52 are equilateral triangles. The lower ends of the support rods 51 are fixed to the bottom surface of the chamber 1. The first frame 5 includes three triangular frames 52, which are located at the top, middle, and bottom of the support rods 51, respectively, to make the connection between the three support rods 51 more secure and improve the stability of the first frame 5. The second frame 6 includes two triangular frames 52, which are located at the top and middle of the support rods 51, respectively, so that the height of the first frame 5 is greater than the height of the second frame 6.

[0033] Please see Figure 1 As shown, the height of the first frame 5 is greater than the height of the second frame 6. The larger diameter end of the limiting member 4 is fixedly connected to the triangular frame 52 at the top of the first frame 5, and the smaller diameter end of the limiting member 4 is fixedly connected to the triangular frame 52 at the top of the second frame 6. The height difference between the first frame 5 and the second frame 6 is less than the height of the limiting member 4. The height difference between the first frame 5 and the second frame 6 provides double fixation and support for the limiting member 4, improving its strength and preventing deformation and damage.

[0034] Please see Figure 1 As shown, one side of the clamping hole 21 has an arc-shaped wall, and the other side has an obtuse angle. The locking member 3 is located on the arc-shaped side. In this embodiment, there are two clamping holes 21 with different diameters to accommodate corrugated rolls of different diameters. The arc-shaped hole wall has an arc greater than 180°. The locking member 3 is located in the middle of the arc-shaped hole wall and points towards the middle of the obtuse angle. The locking member 3 presses the corrugated roll against the two sides of the obtuse angle, thus clamping and fixing the upper end of the corrugated roll.

[0035] Please see Figure 2As shown, the locking component 3 includes a fixed sleeve 31, a locking pin 32, and a locking bolt 33. The fixed sleeve 31 is fixedly installed on the standing platform 2. The locking pin 32 is movably accommodated within the fixed sleeve 31. The top of the fixed sleeve 31 is provided with a threaded hole 34 for threaded installation of the locking bolt 33. The locking bolt 33 is used to abut against the locking pin 32 to fix the locking pin 32. In this embodiment, two nuts are fixedly connected to the top of the fixed sleeve 31, and the threaded hole 34 is located in the nuts. When clamping the corrugated roll, the locking bolt 33 is loosened to allow the locking pin 32 to move within the fixed sleeve 31. After one end of the locking pin 32 is pressed against the corrugated roll, the locking bolt 33 is tightened to abut against the locking pin 32, preventing the locking pin 32 from moving away from the corrugated roll, thereby achieving the purpose of fixing the corrugated roll.

[0036] Please see Figure 1 As shown, a cover plate 7 is provided on the standing platform 2. One side of the cover plate 7 is hinged to the standing platform 2, and the cover plate 7 is used to cover the clamping hole 21. In this embodiment, the cover plate 7 is made of metal material. The cover plate 7 covers the clamping hole 21 when welding is not required, which can prevent workers or tools from accidentally falling into the chamber 1 from the clamping hole 21, thereby improving safety.

[0037] Please see Figure 1 As shown, the standing platform 2 is provided with a groove 22, which is formed by recessing downwards from the top of the standing platform 2. The clamping hole 21 is located in the groove 22, and the groove 22 is used to accommodate the cover plate 7. In this embodiment, the depth of the groove 22 is equal to the thickness of the cover plate 7, so that the cover plate 7 is flush with the surface of the standing platform 2, preventing workers from tripping over the cover plate 7.

[0038] Please see Figure 1 As shown, a handle 71 is provided on the cover plate 7. The handle 71 is located on the side of the cover plate 7 away from the clamping hole 21. The handle 71 is provided to facilitate workers to lift the cover plate 7.
