Description
TECHNICAL FIELD
[0001] The utility model relates to paper product processing industry field, and specifically relates to a paper roll machine roll-off mechanism. BACKGROUND
[0002] In today's papermaking and related paper product processing industry, the paper roll machine roll-off mechanism is the key equipment to realize paper roll unwinding, conveying and further processing. The traditional paper roll machine roll-off mechanism has many defects.
[0003] On the one hand, in the conveying and processing of the paper roll, the function is relatively single. Most of the traditional roll-off mechanisms can only realize simple unwinding operation, and cannot flexibly cut or directly output the paper roll according to the actual demand, which is difficult to meet the diversified production requirements. For example, in some packaging, printing and other production links that require different lengths of paper roll, the traditional equipment needs additional manual or other complex equipment for cutting, which not only increases the production cost, but also reduces the production efficiency.
[0004] On the other hand, in the conveying process of the paper roll, the protection and cleaning measures for the paper roll are insufficient. The compression roller of the traditional roll-off mechanism usually does not have the function of cleaning the side surface of the paper roll, which leads to the fact that the paper roll is easily contaminated with dust, impurities and the like during the conveying process, affecting the quality of the paper roll, especially for some paper products with high cleanliness requirements, such as household paper, medical paper roll, etc. This problem is more prominent.
[0005] In addition, the operation convenience and equipment maintenance of the traditional paper roll machine roll-off mechanism are poor. The unreasonable design of the equipment structure makes it inconvenient for the operator to perform unwinding, adjustment and other operations, and the equipment is difficult to overhaul and maintain. Once a fault occurs, the maintenance time is long, which affects the production progress. At the same time, there is a lack of transparent shielding door and other protection design, which has certain safety hazards.
[0006] In summary, it is of great practical significance to develop a paper roll machine roll-off mechanism that can flexibly meet the direct unwinding output or the output after cutting of the paper roll, has a paper roll cleaning function, is convenient to operate and safe. This patent is based on this background and is designed to research and develop. UTILITY MODEL CONTENT

[0029] An assembly consisting of a pre-feeding upper pressure roller 3 and a pre-feeding lower pressure roller 4 is installed next to the roll feed roller shaft 2, ensuring smooth relative rotation between them. A sponge layer 14 is wrapped around the outer surfaces of the pre-feeding upper pressure roller 3 and the pre-feeding lower pressure roller 4.
