[0002] Paper barrels are also called fiberboard barrels. The barrel body is made of eight layers of kraft paper glued by polyvinyl alcohol solution. The barrel cover and barrel bottom are made of five layers of plywood glued by machine. Nowadays, paper barrels are widely used in foreign trade export packaging, chemical industry, medicine, food and other fields. In the production and processing of paper tubes, the bottom paper of the paper barrel needs to be connected to the paper tube.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 3 A paper barrel bottom paper positioning device comprises a bottom plate 1 and a support ring 2, the support ring 2 is arranged above the bottom plate 1, the top of the bottom plate 1 is fixedly connected with a first pad 3 and a second pad 4, the bottom of the support ring 2 is fixedly connected with a support rod 6, the bottom of the support rod 6 is fixedly connected with the bottom plate 1, the top of the support ring 2 is fixedly connected with a fixing rod 7, and the other end of the fixing rod 7 is fixedly connected with a first paper tube guide block 8;

[0020] A travel rod 9 is fixedly connected to the outer wall of the support ring 2, and a clamping rod 13 and an L-shaped bottom paper positioning frame 12 are slidably sleeved on the rod wall of the travel rod 9. The bottom of the L-shaped bottom paper positioning frame 12 is slidably connected to the top of the bottom plate 1, and the top of the clamping rod 13 is fixedly connected to the second paper tube guide block 14.

[0021] A gap is provided between the second pad 4 and the first pad 3 so that the pad will not affect the downward insertion of the paper tube.

[0022] Guide frames 5 are symmetrically arranged on both sides of the first pad 3. The guide frames 5 are fixedly connected to the bottom plate 1 and are arranged at an angle. The guide frames 5 can guide the bottom paper of the paper barrel placed on the pad, so that the bottom paper is placed between the three L-shaped bottom paper positioning frames 12.

[0023] A spring 11 is provided on the side of the L-shaped bottom paper positioning frame 12 away from the clamping rod 13. The spring 11 is sleeved on the outer wall of the travel rod 9, and a limit block 10 is provided at the other end of the spring 11. The limit block 10 is fixedly connected to the end of the travel rod 9. The elastic force of the spring 11 can push the clamping rod 13 and the L-shaped bottom paper positioning frame 12 toward the support ring 2.

[0024] The tops of the first paper tube guide block 8 and the second paper tube guide block 14 are both provided with downwardly inclined surfaces, and the inclined surfaces can make it easier for the paper tube to be inserted between the first paper tube guide block 8 and the three second paper tube guide blocks 14 .

[0025] An arc-shaped chamfer is provided on the inner top wall of the support ring 2 to facilitate the paper tube to be inserted into the interior of the support ring 2 .

[0026] The second pad 4 is arranged just below the center of the support ring 2 , so that the second pad 4 can effectively support the base paper.

[0027] Working principle: When in use, place the bottom paper of the paper barrel on the first pad 3 and push it horizontally along the guide frame 5 to the bottom of the support ring 2. The bottom paper will move along the first pad 3 to the second pad 4 and be positioned by three L-shaped bottom paper positioning frames 12 to ensure that the bottom paper is placed concentrically with the support ring 2.

[0028] Then, the barrel body of the paper drum, i.e., the paper tube, is inserted downward into the interior of the support ring 2 along the inclined surfaces of the three second paper tube guide blocks 14. When the outer tube wall of the paper tube contacts the inclined surfaces of the second paper tube guide blocks 14, the second paper tube guide blocks 14 will be pushed to drive the L-shaped bottom paper positioning frame 12 to move outward along the stroke rod 9. After the paper tube passes through the support ring 2, it can be sleeved on the bottom paper.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
