Description

Technical Field

[0001] This utility model relates to the field of roll changing, and in particular to an automatic roll changing device for paper machine water jets. Background Technology

[0002] The automatic paper roll changer is a device used in the paper production process to automatically change paper rolls, which can improve the production efficiency of paper machines, reduce manual operation, and ensure the continuity of the production process.

[0003] During paper roll changing, the two water needles on the support move to the middle of the paper sheet. Then, the high-pressure water pump and glue pump are turned on, and the two water needles begin to move to cut out the paper tip. Under the action of the glue, the paper tip is adhered to the paper roll. The paper sheet is wound onto the paper roll as it rotates. The glue valve is then closed, and the two water needles continue to move to the paper edge on both sides to completely cut and separate the paper sheet from the previous roll, thus completing the roll changing. During the movement of the water needles, the internal liquid flow causes them to wobble due to the force exerted during movement, which affects the flat cutting of the paper and thus impacts the effectiveness of the automatic water needle roll changing device on the paper machine. Utility Model Content

[0004] The technical problem this invention aims to solve is that when the water needle moves, the internal liquid flow causes the water needle to shake due to the force exerted during movement, which affects the flat cutting of the paper and thus affects the performance of the automatic water needle roll changing device of the paper machine.

These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Figures 1 to 6 The paper machine automatic roll changing device shown includes a support 1, with water needles 2 on one side of the support 1, a paper roll 3 on another side of the support 1, and a stabilizing device 4 on another side of the support 1. The stabilizing device 4 supports and stabilizes the water needles 2 via a stabilizing plate 42. During paper roll changing, the support device on the support 1 stabilizes the water needles 2. Then, the two water needles 2 on the support 1 move to the middle of the paper sheet, and the high-pressure water pump and glue pump connected to the water needles 2 are turned on. The two water needles 2 begin to move and cut out paper tips. Under the action of the glue, the paper tips are adhered to the paper roll 3. The paper sheet is wound onto the paper roll 3 as the paper roll 3 rotates. The glue valve is then closed, and the two water needles 2 continue to move to the paper edges on both sides, completely cutting and separating the paper sheets from the previous roll, thus completing the roll changing.

[0026] Figures 1 to 6The stabilizing device 4 shown includes a slide rail 41, a stabilizing plate 42, a through hole 43 on the stabilizing plate 42, and a lubrication assembly 44. The slide rail 41 is located on one side of the bracket 1, and the stabilizing plate 42 is located inside the slide rail 41. The size of the through hole 43 on one side of the stabilizing plate 42 is adapted to the size of the water needle head 2. The stabilizing plate 42 and the through hole 43 on one side are connected to the water needle head 2. The lubrication assembly 44 is located on one side of the stabilizing plate 42 to lubricate the contact area between the slide rail 41 and the stabilizing plate 42.

[0027] Figures 1 to 6 Before using the water needle head 2, the through hole 43 of the stabilizing plate 42 is connected and fixed to the water needle head 2. Then, the lubrication assembly 44 is used to add lubricating oil inside the stabilizing plate 42 and the slide rail 41. When the water needle head 2 moves, it drives the stabilizing plate 42 to move inside the slide rail 41. At this time, the lubricating oil reduces the friction between the stabilizing plate 42 and the slide rail 41, making it easier for the stabilizing plate 42 to move inside the slide rail 41. The stabilizing plate 42 better supports and stabilizes the water needle head 2. By using the stabilizing device 4, the water needle head 2 can be supported and stabilized, so that the water needle head 2 can move stably. This avoids the water needle head 2 from shaking due to the internal liquid flow during movement, which would affect the flat cutting of the paper and thus improve the performance of the automatic water needle roll changing device of the paper machine.

[0028] Figures 1 to 6 The stabilizing plate 42 shown has a lubrication assembly 44 on one side, including a bolt 441, a mounting plate 442, a storage tube 443, an electric telescopic rod 444, a piston 445, an oil outlet pipe 446, and a guide groove 447 opened on one side of the stabilizing plate. The bolt 441 is inserted into the mounting plate 442 to connect with the stabilizing plate 42. The storage tube 443 is located on the mounting plate 442 and stores lubricating oil inside. The electric telescopic rod 444 is located on the storage tube 443. The piston 445 is located at the output end of the electric telescopic rod 444 and is located inside the storage tube 443. The oil outlet pipe 446 is located in the storage tube 443 away from the electric telescopic rod 444, and the outlet of the oil outlet pipe 446 is close to the guide groove 447 on the side of the stabilizing plate 42. Figures 1 to 6As shown, when using the lubrication assembly 44, the mounting plate 442 is moved to contact the stabilizing plate 42. Then, the bolt 441 is rotated to insert the bolt 441 into one side of the mounting plate 442 for threaded fixation with the stabilizing plate 42. The storage tube 443 fixed on one side of the mounting plate 442 is then installed onto one side of the stabilizing plate 42. Then, the electric telescopic rod 444 fixed on one side of the storage tube 443 is activated, causing the piston 445 fixed at the output end of the electric telescopic rod 444 to move inside the storage tube 443, pushing the lubricating oil inside the storage tube 443. The solenoid valve on one side of the oil outlet pipe 446 is opened, allowing the lubricating oil to reach the inside of the oil outlet pipe 446, and then to the guide groove 447 on one side of the stabilizing plate 42. Finally, the lubricating oil reaches the area between the slide rail 41 and the stabilizing plate 42 through the guide groove 447 to lubricate the contact area between the stabilizing plate 42 and the slide rail 41, making it easier for the stabilizing plate 42 to move inside the slide rail 41.

[0029] Figures 1 to 6 The stabilizing plate 42 shown has a support plate 448 on the side near the oil outlet pipe 446, which provides limiting support for the oil outlet pipe 446. The support plate 448 is fixed to one side of the stabilizing plate 42 and contacts the oil outlet pipe 446 to support and limit its movement, preventing stress on the oil outlet pipe 446 and thus avoiding the situation where the outlet of the oil outlet pipe 446 moves away from the guide groove 447 on the side of the stabilizing plate 42. Several anti-slip blocks 449 are provided on both sides of the mounting plate 442 to increase the friction on both sides. These anti-slip blocks 449 are used to fix the mounting plate 442, increasing the friction on both sides and making the mounting plate 442 easier to hold and move.

[0030] Figures 1 to 6 A positioning plate 4410 is provided on one side of the stabilizing plate 42 to position the mounting plate 442 on one side of the stabilizing plate 42. By fixing the positioning plate 4410 to one side of the stabilizing plate 42, the position of the mounting plate 442 and the stabilizing plate 42 is quickly positioned, facilitating subsequent fixing of the mounting plate 442 with bolts 441. A reinforcing plate 4411 is provided on one side of the storage tube 443, and one side of the reinforcing plate 4411 is connected to the electric telescopic rod 444 to improve the connection strength between the storage tube 443 and the electric telescopic rod 444. By fixing the reinforcing plate 4411 to the electric telescopic rod 444 and the storage tube 443, the connection strength between the electric telescopic rod 444 and the storage tube 443 is improved, preventing the electric telescopic rod 444 from separating from the storage tube 443 under stress.

[0031] Figures 1 to 6The stabilizing plate 42 shown has several balls 45 on one side to reduce the friction between the stabilizing plate 42 and the slide rail 41. By having several balls 45 roll on one side of the stabilizing plate 42, the contact area between the stabilizing plate 42 and the slide rail 41 is reduced, thereby reducing the friction between the stabilizing plate 42 and the slide rail 41, making it easier for the stabilizing plate 42 to move inside the slide rail 41.

[0032] Working principle: When changing paper rolls, the support device on the bracket 1 supports and stabilizes the water needles 2. Then, the two water needles 2 on the bracket 1 move to the middle of the paper sheet, turn on the high-pressure water pump and glue pump connected to the water needles 2, and the two water needles 2 begin to move to cut out the paper tip. Under the action of the glue, the paper tip is stuck to the paper roll 3. The paper sheet is rolled onto the paper roll 3 as the paper roll 3 rotates. Then, the glue spray valve is closed, and the two water needles 2 continue to move to the paper edge on both sides to completely cut and separate the paper sheet from the previous paper roll, thus completing the roll change. Before using the water needle head 2, connect and fix the through hole 43 of the stabilizing plate 42 to the water needle head 2. Then, lubricate the assembly 44 and add lubricating oil inside the stabilizing plate 42 and the slide rail 41. When the water needle head 2 moves, it drives the stabilizing plate 42 to move inside the slide rail 41. At this time, the lubricating oil reduces the friction between the stabilizing plate 42 and the slide rail 41, making it easier for the stabilizing plate 42 to move inside the slide rail 41. The stabilizing plate 42 better supports and stabilizes the water needle head 2. By using the stabilizing device 4, the water needle head 2 can be supported and stabilized, so that the water needle head 2 can move stably. This avoids the water needle head 2 from shaking due to the internal liquid flow during movement, which would affect the flat cutting of the paper and thus improve the performance of the automatic water needle roll changing device of the paper machine.
