Description

Technical Field

[0001] The utility model relates to the technical field of drying cylinder guide roller devices, in particular to a drying cylinder guide roller device which is convenient to replace and is used in a pulp cleaning production process. Background Art

[0002] With the rapid development of large paper machines, paper machines often have multiple sets of guide rollers working together. The main functions of paper machine guide rollers on paper machines are: (1) to provide a moving surface; (2) to keep pace with the speed of the paper machine; (3) to support fabrics or paper webs. However, after long-term use, guide rollers will inevitably wear out and need to be maintained and replaced regularly.

[0003] At present, in the existing utility model, the guide roller replacement of the drying section of the paper machine is applied. Since the shape of the column plate and the cantilever support plate connected to the bottom frame plate seat matches the shape of the gap between the two drying cylinders of the drying section of the paper machine, the column plate and the cantilever support plate can be directly inserted into the gap under the guide roller, and then the guide roller bearing seat on the paper machine frame is loosened, the guide roller is removed and placed directly on the upper side of the cantilever support plate, the guide roller is placed in the arc support groove, and the guide roller bearing seat to be replaced is fixed on the mounting seat plate of the front end cantilever of the cantilever support plate; at the same time, a counterweight block with the same weight as the corresponding guide roller is assembled at the rear end of the bottom frame plate seat before disassembly. In this way, the guide roller can be quickly and conveniently pulled out from the paper machine frame through the balance bracket composed of the cantilever support plate, the column plate and the bottom frame plate seat; without removing any irrelevant equipment, the replacement time of the guide roller in the drying section is effectively shortened, the downtime of the paper machine is shortened, the control is convenient, and the replacement difficulty is reduced, thereby improving work efficiency and economic benefits.

[0004] For example, the guide roller changing device for a paper machine disclosed in the authorization number CN213804624U is used for disassembly, assembly and replacement of guide rollers on a paper machine frame, and includes a base frame plate seat, four guide wheels, two column plates and a cantilever support plate, wherein the four guide wheels are mounted on the four legs of the base frame plate seat, and the two column plates are vertically fixed side by side at the front end of the base frame plate seat; the cantilever support plate is connected to the top ends of the two column plates in parallel along the length direction of the base frame plate seat, and the front end of the cantilever support plate is cantilevered and inserted to receive the lower end of the guide roller on the paper machine frame; a support plate for balancing the cantilever support plate is installed at the rear end of the base frame plate seat The front end cantilever bears the weight of the guide roller with a counterweight block; the cantilever support plate, two column plates and the bottom frame plate seat are connected in sequence to form a balance bracket between the guide roller and the counterweight block; when the guide roller is disassembled, the bottom frame plate seat is driven or driven by the rotating guide wheel to drive the cantilever support plate to pull the guide roller out of the paper machine frame; when the guide roller is installed, one end of the guide roller is inserted into the outer end of the paper machine frame through a crane or a hanging chain, and the other end of the guide roller is fixed to the front end cantilever of the cantilever support plate, and the bottom frame plate seat is pushed or driven to drive the cantilever support plate to move horizontally along the axial direction of the guide roller and insert the guide roller into the two ends of the paper machine frame. However, such a guide roller changing device for a paper machine is not convenient for supporting and disassembling guide rollers of different heights, and is not convenient for supporting and disassembling guide rollers at different distances.

[0005] It can be seen from the solutions disclosed in the above-mentioned existing patent documents that it is inconvenient to support and disassemble guide rollers at different heights, and it is inconvenient to support and disassemble guide rollers at different distances. Therefore, it is necessary to improve the existing technology. Utility Model Content
