Description

Technical Field

[0001] The utility model relates to the field of papermaking equipment, in particular to a roller device of a papermaking machine. Background Art

[0002] In the current old-fashioned paper machine structure, the blanket is inside the frame. When the operator needs to replace the blanket, the column frame blocks it and there is no cantilever blanket replacement device. The operator can only remove the pull-out block under the guide roller and push the blanket out and in little by little, which is very time-consuming. It usually takes four hours for a skilled operator to complete the entire blanket replacement work. The labor intensity of the workers is high and there are many types of work involved, which brings inconvenience to the blanket replacement process and low efficiency. When the sling is used in the blanket replacement process, each operation varies from person to person, so there are differences in methods and time consumption, which is easy to produce deviations, there is a large uncertainty, and it takes a long time, so there are certain safety hazards. In the old-fashioned paper machine structure, the water collection component is connected to the roller body seat. When the roller body needs to be removed for maintenance, the water collection component also needs to be removed, which is a lot of work. Utility Model Content

[0023] See also Figures 1 to 3, is a paper machine roller device of the utility model, which includes a roller body 1, a positioning assembly 2, a blanket replacement assembly 3, a driver 4, a water receiving assembly 5 and a connecting plate 6. The positioning assembly 2 includes a transmission side frame 21, an operating side frame 22 and a cantilever beam 23, the transmission side frame 21 and the operating side frame 22 are fixed to the ground, the roller body 1 is connected between the transmission side frame 21 and the operating side frame 22, and the cantilever beam 23 is connected to the transmission side frame 21 and the operating side frame 22 at the same time. The blanket replacement assembly 3 includes a pull rod 31, a first extraction seat 32 and a second extraction seat 33, the pull rod 31 is connected to one end of the cantilever beam 23 away from the operating side frame 22, and the pull rod 31 is fixed to the ground; the first extraction seat 32 and the second extraction seat 33 are respectively arranged on the upper and lower sides of the operating side frame 22.

[0024] It can be understood that after the first withdrawal seat 32 and the second withdrawal seat 33 are withdrawn, a space for changing blankets can be created, and the blankets can be directly inserted into the original setting space of the first withdrawal seat 32 and the second withdrawal seat 33 for installation and replacement. The blanket replacement time of the roller part is greatly shortened, the safety is improved, the work efficiency is improved, the process of pulling out the blankets is simplified, the dependence on the operator's technical proficiency is reduced, the difficulty and labor intensity of blanket replacement work are reduced, and the production arrangement plan of base paper production is beneficial.

[0025] Among them, the transmission side frame 21, the operating side frame 22 and the pull rod 31 are arranged parallel to each other, and the cantilever beam 23 is perpendicular to the transmission side frame 21 and the operating side frame 22. The transmission side frame 21, the operating side frame 22 and the pull rod 31 are all fixed on the ground through the fastening plate 24, and the fastening plate 24 is connected with a fastener, which can be an explosive bolt, so that the transmission side frame 21, the operating side frame 22 and the pull rod 31 can be stably fixed on the ground. The cantilever beam 23 is supported and connected and fixed by the operating side frame 22 and the transmission side frame 21. The pull rod 31 is fixedly connected to the cantilever beam 23 and also fixedly connected to the fastening plate 24. The pull rod 31 serves as a locking fulcrum to ensure that after the first extraction seat 32 and the second extraction seat 33 are extracted, the cantilever beam 23 and the roller body 1 will not fall to the operating side, thereby ensuring the safety during the carpet changing process. The number of the pull rods 31 can be multiple, which can strengthen the support force of the cantilever beam 23, making the overall structure more stable and having higher strength.

[0026] Further, the connecting plate 6 is connected to the roller body 1, the driver 4 is installed on the operating side frame 22, and the output end of the driver 4 is connected to the connecting plate 6, and the driver 4 is used to drive the connecting plate 6 to move, so as to drive the roller body 1 to move. Specifically, the driver 4 can drive the roller body 1 to move, so as to drive the roller body 1 to move within a certain range, so as to facilitate the position change of the roller body 1. The driver 4 can be a pneumatic driver, a hydraulic driver or an electric driver.

[0027] In addition, the water receiving assembly 5 is connected to the connecting plate 6, and the water receiving assembly 5 is arranged corresponding to the roller body 1, and is used to process the water on the roller body 1. Specifically, the water receiving assembly 5 includes a water receiving tray 53 connected to the connecting plate 6 and a scraper 52 arranged on the water receiving tray 53, and the water receiving tray 53 is arranged corresponding to the roller body 1. The water receiving tray 53 is provided with a drainage hole and a drainage pipe arranged corresponding to the drainage hole. It can be understood that since the wet blanket in the blanket runs with water on the roller body 1, there will be water on the roller body 1. If there is too much water during the operation, it will cause splashing and affect the production process. The function of the scraper 52 is to scrape the water on the roller body 1 or the water in the wet blanket into the water receiving tray 53, and when the roller body 1 runs at high speed, a lot of water will automatically splash out of the wet blanket. At this time, the water receiving tray 53 can also receive the splashed water into the drainage hole and drain it along the drainage pipe to ensure the normal progress of the papermaking process.

[0028] There are multiple scrapers 52 , and the multiple scrapers 52 scrape the water retained on the roller body 1 together. The scrapers 52 are arranged at intervals along the circumferential direction of the roller body 1 .

[0029] In general, the paper machine roller device can create a space for changing blankets through the arrangement of the first extraction seat 32 and the second extraction seat 33. The blanket can be directly inserted into the original setting space of the first extraction seat 32 and the second extraction seat 33 for installation and replacement. The blanket replacement time of the roller part is greatly shortened, the safety is improved, the work efficiency is improved, the process of pulling out the blanket is simplified, the dependence on the operator's process proficiency is reduced, the difficulty and labor intensity of blanket replacement work are reduced, and it is beneficial to the production arrangement plan of base paper production. At the same time, through the arrangement of the water receiving component 5, it can receive moisture and drainage from the roller body 1 during operation, ensure the normal progress of the papermaking process, and improve the stability of the quality of the finished paper. At the same time, the driver 4 can drive the roller body 1 to move, so as to drive the roller body 1 to move within a certain range, so as to facilitate the position replacement of the roller body 1. And because the water receiving component 5 is connected to the connecting plate 6, when the roller body 1 needs to be disassembled for maintenance, it is not necessary to disassemble the water receiving component 5, thereby reducing the workload.

[0030] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should fall within the scope of the claims of the utility model.
