Problems solved by technology

This method for changing tires is labor-intensive and time-consuming, and in this case, the effective working time of the machine will be greatly reduced
In addition, the disassembly of the roller shaft requires a very large space, which increases the width of the paper machine workshop, and in addition, there are hidden dangers in terms of work safety

Embodiment Construction

[0020] Figure 1 shows a mechanical structure formed by a closed tire ring. In this case, the belt calender comprises a calender belt 2 running around a main control roller 3 which is used to adjust the pressure of the belt 2 or / and the length of the treatment zone when it 3 At least some of them can be moved. The calender belt 2 follows the ring of the installed roller shaft 5 and travels outside the roller shaft 5 , and then an adjustable calendering area is formed between the belt belt 2 and the roller shaft 5 in the longitudinal direction. The dotted line in the figure shows that the nip roller 4 as a pressing mechanism may press the roller 5 against the belt 2 to form a strong pressure in the calendering zone of the nip area. The roller shaft 4 as the pressing mechanism can be of other shapes or a shrinking and pressing structure with a fixed shape. In addition, this pressing and pressing mechanism can be composed of more continuous parts in the transverse direction of th...

Abstract

The present invention relates to a device and a method for exchanging endless tires or corresponding parts in a paper / board machine or polishing machine, which must include at least one ring of the tire. The device includes at least one support mechanism extending transversely across the machine to define a receiving mechanism mounted on the frame mechanism of the machine inside the tire loop. The support mechanism is assembled to the receiving mechanism and can be pulled inward or outward to the desired position to change the tire while the machine is running. The end region of the support means is provided with at least one switching position, the frame means inside the rim of the tire can be moved away from at least one side of said frame means by means of the power conduction of the switching points mounted on the support means, the support means is removed from the receiving device The tire is stretched out to be in the extended state in the transverse direction of the machine and the tire ring is directly or indirectly wrapped around it, and then the tire is removed from the machine or installed on the machine by a corresponding device.

Description

technical field [0001] The invention relates to a device and a method for changing an endless belt or a corresponding component in a paper / board machine or in a polishing machine, which comprises at least one endless belt ring. The technical solution according to the invention can be applied to replace conveyor belts and felts of various paper / board machines and textile machines. Replacing conveyor belts has always been considered difficult, and these problems are exacerbated by increasing the width of the paper machine. The size of the conveyor belt, especially the width of the conveyor belt, increases accordingly, and it is also more difficult to handle and pass the conveyor belt through the machine in such a short distance. [0002] The invention can be particularly effectively applied to the replacement of endless metal conveyor belts. It is difficult to replace long-distance endless conveyor belts, especially calenders for metal conveyor belts. Such a calender has a co...
