Description

Quick net change belt cleaning device for paper machine Technical Field The invention relates to the field of forming wire equipment, in particular to a quick wire-changing cleaning device for a paper machine. Background The special paper is used for manufacturing cigarettes, and the production process of the special paper needs to be subjected to multiple steps, such as raw material preparation, pulping, seasoning addition, post-manufacturing processing and the like. Wherein, the papermaking comprises the steps of paper pulp screening, squeezing, dewatering, drying and the like. The pulp is fed to a head box of a paper machine, and the pulp is uniformly sprayed to a net part of the paper machine through the head box, so that the fibers are preliminarily interweaved and formed at the net part to form a wet paper sheet, and meanwhile, the net part can be preliminarily dehydrated, so that the wet paper sheet has certain wet strength, and is convenient for subsequent transmission and further processing. The press dewatering is that the wet paper sheet is transferred from the wire part to the press part, and a certain pressure is applied by a press roll and other devices, so that the moisture in the wet paper sheet is further removed, the performances of tightness and the like of the paper sheet are improved, and the burden is reduced for subsequent drying. The pulp wire-up needs to be completed by a corresponding device, namely a forming wire device. At present, the forming wire equipment types are more, for example, a three-layer forming wire for papermaking disclosed in a Chinese patent with publication number CN111764191B comprises a forming device, a support frame and a water absorbing device main body, wherein the forming device is fixedly arranged in the support frame, the water absorbing device main body is fixedly arranged at one end edge inside the support frame, the three-layer forming wire is movably arranged in the forming device, the inner surface of the three-layer forming wire is tightly contacted with a driving roller, two end faces of the driving roller are both welded with positioning shafts, one end of each positioning shaft is fixedly connected with a first driving motor, a support frame is fixedly arranged in the support frame, and a slurry spraying port is welded on the top surface of the support frame. By using the forming wire provided by the patent, paper pulp can be filtered through the three-layer forming wire, the retention rate of paper pulp fibers on the surface of the three-layer forming wire can be improved, and the water absorbing cotton conveyer belt is added on the bottom surface of the three-layer forming wire to absorb water on the paper pulp, so that the dehydration speed and the production efficiency of the forming wire are improved. Although the forming wire provided by the above patent enables the formation of pulp, it has some drawbacks. For example, the forming wire is directly sleeved on the outer side of the roller body and stably supports paper pulp under the support of the roller body. However, if the mesh body of the forming mesh device is to be disassembled according to the requirement for maintenance or replacement, the limitation of the mesh body of the forming mesh device is released by disassembling the roll body, and then the disassembly of the mesh body of the forming mesh device can be realized, so that the operation is not beneficial to efficiently completing the disassembly task of the forming mesh. In addition, in the process of supporting the paper pulp by the forming net, part of scraps block the forming net, and the forming net equipment is not provided with a cleaning structure, so that the dewatering of the paper pulp is not facilitated. Disclosure of Invention The invention aims to provide a quick net-changing cleaning device for a paper machine, and aims to solve the problem that forming net equipment is inconvenient to detach a net body. The quick net-changing cleaning device for the paper machine comprises a frame, wherein a forming net body is arranged at the top of the frame and is arranged along the length direction of the frame, a plurality of groups of supporting rollers are arranged at the top of the frame side by side, each group of supporting rollers is arranged along the width direction of the frame, each supporting roller comprises a first roller body, a second roller body and a supporting mechanism, the first roller body and the second roller body are positioned on the same straight line, one ends close to each other are detachably connected in an inserting mode and penetrate through the forming net body, one ends, far away from each other, of the first roller body and the second roller body are respectively connected with the supporting mechanism, and the supporting mechanism is adjustably arranged on the frame. As one embodiment of the invention, a plum blossom hole is formed in one end, close to the second roller body, of the fir
