Description

Technical Field

[0001] The utility model relates to the technical field of kitchen paper, in particular to a TAD kitchen paper high-speed paper folding machine. Background Art

[0002] TAD kitchen paper is produced using through-air drying technology. This technology represents a major innovation in tissue production systems, designed to improve paper quality. The key to this technology is reducing compression during the production process, imparting a three-dimensional structure to the paper, significantly improving its softness, bulk, and absorbency. TAD enables the paper to absorb 15 times its own weight in water, far exceeding traditional products.

[0003] In order to reduce the floor space occupied by kitchen paper and facilitate use, stacking and transportation, kitchen paper needs to be folded by a folding machine. When unfolded, the kitchen paper is large in size and occupies relatively more space, which causes inconvenience during storage and transportation. By folding, storage space can be saved, transportation costs can be reduced, and it is more convenient to use and carry. Folding and sealing the packaging reduces contact with the external environment, thereby reducing the risk of contamination.

[0004] Due to the loose structure of TAD base paper, the existing vacuum chamber is prone to vacuum leakage, resulting in unstable adsorption. The feed roller of the loose base paper folding machine is prone to knife jamming, which reduces the equipment service life and product production efficiency. Utility Model Content

[0005] The purpose of the present invention is to provide a TAD kitchen paper high-speed folding machine to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A TAD kitchen paper high-speed folding machine comprises a wall panel, a bottom blade roller arranged in a symmetrical structure, a paper folding roller, a vacuum tube, a reinforced adsorption and blocking roller, and an upper blade. Two bottom blade rollers are symmetrically installed on the wall panel in parallel. The vacuum tube is connected to the air outlets of the two bottom blade rollers respectively. The two vacuum tube outlets are connected to a vacuum device via a connecting tube. The reinforced adsorption and blocking roller is located parallel to the two bottom blade rollers on the side close to the outside.

[0008] The bottom knife roller is evenly distributed with knife roller air chambers, and the outer circumferential wall of the knife roller air chamber is evenly penetrated with suction adsorption holes. There are four suction adsorption holes on each knife roller air chamber, and the suction adsorption holes pass through the knife roller air chamber and are connected to the vacuum tube.

[0009] As a preferred solution of the present invention, the upper blade is located on the two bottom knife rollers, and the outer circumferential wall of each bottom knife roller is evenly connected with a bottom blade used in conjunction with the upper blade. The bottom blade on the outer circumferential wall of one of the bottom knife rollers is engaged and pushed with the suction adsorption hole on the other bottom knife roller close to one side.

[0010] As a preferred solution of the present invention, the reinforced adsorption sealing roller is connected to the wall panel, and a sealing plug is provided on the outer circumferential wall of the reinforced adsorption sealing roller for engaging and sealing the suction adsorption holes on the outer wall of the bottom knife roller. The sealing plug is engaged and sealed with the suction adsorption holes on the outer wall of the bottom knife roller, and the reinforced adsorption sealing roller moves synchronously with the bottom knife roller.

[0011] As a preferred solution of the present invention, the folding roller has a symmetrical structure and is located below one side of one of the bottom knife rollers. Folders for folding are evenly distributed on the outer circumferential wall of each folding roller. The folding devices are arranged in an externally protruding conical structure. A push-folding adsorption hole is provided between the two folding devices on the outer circumferential wall of the folding roller. The entrance structure of the push-folding adsorption hole matches the outer wall structure of the folding device.

[0012] As a preferred solution of the present invention, the folding device on one of the folding rollers is engaged and connected with the pushing and folding adsorption hole on the other folding roller adjacent to it.

[0013] As a preferred solution of the present invention, the air outlet at one end of the folding device is connected to the vacuum equipment through a connecting pipe.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In response to the problems in the background technology, the present invention provides a TAD kitchen paper folding machine with stable adsorption. A reinforced adsorption blocking roller is provided on the outer side of the bottom blade roller. A sealing plug is provided on the outer circumferential wall of the reinforced adsorption blocking roller. The sealing plug blocks the suction adsorption holes on the blade roller air chamber on the side away from the upper blade, thereby increasing the adsorption force of the bottom blade roller on the basis of the traditional suction adsorption holes, thereby strengthening the suction force of the kitchen paper on the blade roller air chamber on the side of the upper blade.

[0016] The folding device on one folding roller is meshed with the push-folding suction hole on the folding roller on the other side, ensuring the kitchen paper and the folding roller are conveyed in a close contact manner, ensuring the stable feeding of the subsequent folding roller, and effectively preventing the paper from being too fluffy and causing the knife to get stuck when the base paper is not glued;

[0017] By connecting the vacuum tube to the vacuum equipment, the adsorption force can be effectively controlled to further ensure the stability of the paper during the folding process;

[0018] The design of the TAD kitchen paper high-speed paper folding machine fully considers the characteristics of TAD paper. By strengthening the adsorption force, optimizing the folding mechanism and improving the stability of the equipment, it effectively solves the problems that traditional folding machines may encounter when processing TAD paper. It not only improves production efficiency, but also ensures product quality and reduces waste in the production process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the embodiments of the present invention. Example

[0026] See also Figure 1-5The utility model provides a technical solution: a TAD kitchen paper high-speed paper folding machine, comprising a wall panel 1, a bottom knife roller 2 arranged in a symmetrical structure, a paper folding roller 3, a vacuum tube 4, a reinforced adsorption and blocking roller 5 and an upper blade 6, the two bottom knife rollers 2 are installed parallel and symmetrically on the wall panel 1, the vacuum tube 4 is respectively connected to the air outlets of the two bottom knife rollers 2, the outlets of the two vacuum tubes 4 are connected to the vacuum equipment through connecting tubes, the reinforced adsorption and blocking roller 5 is parallel to the two bottom knife rollers 2 on the side close to the outside; knife roller air chambers 21 are evenly distributed on the bottom knife roller 2, and suction holes 211 are evenly opened on the outer circumferential wall of the knife roller air chamber 21, and there are four suction holes 211 on each knife roller air chamber 21. The suction adsorption hole 211 passes through the knife roller air chamber 21 and is connected to the vacuum tube 4; the upper blade 6 is located on the two bottom knife rollers 2, and the outer circumferential wall of each bottom knife roller 2 is evenly connected with a bottom blade 22 used in conjunction with the upper blade 6, and the bottom blade 22 on the outer circumferential wall of one bottom knife roller 2 is engaged and pushed with the suction adsorption hole 211 on the other bottom knife roller 2 close to one side; the enhanced adsorption sealing roller 5 is connected to the wall panel 1, and the outer circumferential wall of the enhanced adsorption sealing roller 5 is provided with a sealing plug 51 for engaging and sealing the suction adsorption hole 211 on the outer wall of the bottom knife roller 2, the sealing plug 51 is engaged and sealed with the suction adsorption hole 211 on the outer wall of the bottom knife roller 2, and the enhanced adsorption sealing roller 5 moves synchronously with the bottom knife roller 2.

[0027] It should be noted that, in this embodiment, the wall panel 1 serves as the main support structure of the folding machine, ensuring the stability and durability of the machine. The bed knife rollers 2 are installed in parallel and symmetrically. They play a key role in the folding process, supporting and guiding the paper through the machine. The bottom blade 22 on the bed knife roller 2 works in conjunction with the upper blade 6 to achieve precise cutting and subsequent folding.

[0028] Furthermore, a vacuum tube 4 is connected to the air outlet of each bottom knife roller 2 and is connected to a vacuum device through a connecting tube, which creates a negative pressure environment, helping to firmly adsorb the paper onto the bottom knife roller and ensure the stability of the paper during the folding process;

[0029] Furthermore, the enhanced adsorption blocking roller 5 is located on the outer side of the bottom knife roller 2, parallel to the bottom knife roller 2, and blocks the suction adsorption holes 211 on the bottom knife roller 2 slightly away from the cutting side through the sealing plug 51 on its outer circumferential wall, thereby increasing the adsorption force and preventing the paper from sliding or shifting during the folding process. The upper blade 6 is located above the two bottom knife rollers 2 and is used in conjunction with the bottom blade 22 to achieve precise cutting and subsequent folding of the paper. The configuration of the upper and lower blades helps to improve the accuracy and efficiency of cutting and subsequent folding.

[0030] Furthermore, the suction adsorption holes 211 are evenly distributed on the outer circumferential wall of the knife roller air chamber 21, and penetrate the knife roller air chamber 21 and are connected to the vacuum tube 4. Their existence is crucial for creating a negative pressure environment so that the paper can be firmly adsorbed on the bottom knife roller. Strengthening the synchronous movement of the adsorption sealing roller 5 and the bottom knife roller 2 ensures that during the entire folding process, the sealing plug 51 can always effectively block the suction adsorption holes 211 away from the cutting side, thereby maintaining a stable adsorption force. By accurately considering the characteristics of TAD paper, a high-efficiency and high-quality folding effect is achieved. The innovative introduction of the strengthened adsorption sealing roller 5 solves the adsorption instability problem that traditional folding machines may encounter when processing loose paper, thereby improving production efficiency and product quality.

[0031] See also Figure 3 and 5 The folding rollers 3 are symmetrically structured and are located below one side of one of the bottom knife rollers 2. Folders 31 for folding are evenly distributed on the outer circumferential wall of each folding roller 3. The folding rollers 31 are in an externally protruding conical structure. A push-folding adsorption hole 32 is provided between two folding rollers 31 on the outer circumferential wall of the folding roller 3. The entrance structure of the push-folding adsorption hole 32 matches the outer wall structure of the folding roller 31; the folding roller 31 on one of the folding rollers 3 is engaged and connected with the push-folding adsorption hole 32 on the folding roller 3 on the other side it is close to; the air outlet at one end of the folding roller 31 is connected to the vacuum equipment through a connecting pipe.

[0032] It should be noted that, in this embodiment, in the TAD kitchen paper high-speed paper folding machine, the folding roller 3 has a symmetrical structure and is located below one side of the bottom knife roller 2, so that the folding roller can effectively receive the paper conveyed from the bottom knife roller 2 and perform the next folding process. The outer circumferential wall of each folding roller 3 is evenly distributed with folding devices 31. These folding devices 31 adopt an externally protruding conical structure. This shape is conducive to achieving precise folding of the paper.

[0033] During operation, the folding tool 31 is not only responsible for folding the paper, but also forms a push-folding suction hole 32 between the two folding tools 31 through its unique tapered structure. The structure of this hole matches the outer wall structure of the folding tool 31, ensuring that the paper can be stably sucked and pushed during the folding process, effectively improving the accuracy and stability of the folding and preventing the paper from being deflected or wrinkled during the folding process.

[0034] To improve folding efficiency and quality, the folding device 31 on one folding roller is meshed with the push-folding suction hole 32 on the adjacent folding roller. This meshing connection ensures that the paper can be folded smoothly and accurately when transferred from one folding roller 3 to the other. In addition, the air outlet at one end of the folding device 31 is connected to a vacuum device through a connecting pipe. This creates a negative pressure environment during operation, helping to maintain the stability and accuracy of the paper during the folding process.

[0035] This efficient and precise folding mechanism, combined with vacuum adsorption technology, ensures that TAD kitchen paper can maintain high efficiency and product quality during high-speed production, reflecting the innovation and progress of modern paper processing machinery in the pursuit of production efficiency and product quality.

[0036] The working process of this utility model:

[0037] When in use, vacuum is used to transfer the original TAD kitchen paper from the bottom knife roller 2 to the folding roller 3. The enhanced adsorption blocking roller 5 is located on the outer side of the bottom knife roller 2, parallel to the bottom knife roller 2, and blocks the suction adsorption holes 211 on the bottom knife roller 2 slightly away from the cutting side through the sealing plug 51 on its outer circumferential wall, thereby increasing the adsorption force to prevent the paper from sliding or shifting during the folding process. The original TAD kitchen paper is transferred from the bottom knife roller 2 to the folding roller 3 by vacuum. When the folding device 31 at one end of the folding rod is retracted from the V-shaped groove to the other end of the folding roller 3, the folding device 31 is used to feed the paper from between the folding rollers 3 into the V-shaped groove. Folding suction hole 32, and then vacuum maintains the paper in the V-shaped groove of the push folding suction hole 32. When the paper is held early, when the folding roller 3 rotates 90 degrees, the paper can be removed from the V-shaped groove of the push folding suction hole 32, and the folding claws fold the paper. The design of TAD kitchen paper high-speed paper folding machine fully considers the characteristics of TAD paper. By strengthening the adsorption force, optimizing the folding mechanism and improving the stability of the equipment, it effectively solves the problems that traditional folding machines may encounter when processing TAD paper, which not only improves production efficiency, but also ensures product quality and reduces waste in the production process.
