Description

Technical Field

[0001] The utility model relates to the technical field related to papermaking machines, and in particular to a high-pressure hose tightening structure and a high-pressure system for tearing paper webs. Background Art

[0002] Reel change on a paper machine refers to the series of operations performed during the papermaking process when the paper roll currently being wound reaches a predetermined length, diameter, or weight, or when a new roll is needed to continue winding the paper due to other reasons. This process includes stopping the current roll, tearing the paper web, removing the completed roll, installing a new roll, and redirecting the paper web for winding. The goal is to achieve continuous production and ensure that paper can be wound and collected uninterruptedly, thereby improving production efficiency and product quality.

[0003] When tearing a paper web, the force generated by air pressure is usually used. This is achieved by injecting high-pressure gas into a specific space or device, causing the pressure generated by the gas to act on the paper web. When the force generated by the air pressure exceeds the tensile strength of the paper material itself, the paper web will tear.

[0004] In pneumatic paper tearing systems, the high-pressure hose is the pipe used to transmit gas. During installation, it is typically wound halfway around a hose reel before connecting to the cutting nozzle. This allows the hose to move within a fixed width, reducing the possibility of collision and interference with other equipment, components, or operators, and improving work safety and smoothness. However, during actual operation, the high-pressure hose can become loose around the reel, causing the hose to become tangled. The loose hose can also whip or entangle the operator during movement, causing personal injury.

[0005] Currently, no effective solution has been proposed for the problem in the related art that the high-pressure hose may become loose when wound around the hose reel. Utility Model Content

[0202] Connect the air compressor to the first end of the connecting element 131 through a first high-pressure hose and secure them with a clamp;

[0203] Connect one end of the second high-pressure hose to the second end of the connecting element 131 and secure them with a clamp;

[0204] Pass the second end of the second high-pressure hose through the third through-groove element 155 and the adjusting element 151, and then wind it clockwise or counterclockwise along the wire groove or track of the hose reel half a circle. During the winding process, ensure that the air pipe is evenly distributed and does not cross, twist or over-stretch. After winding half a circle, connect it to the cutting nozzle and fix it with a clamp.

[0205] (2) Debugging work

[0206] Twist the second locking element 181 counterclockwise to separate it from the second limiting element 171;

[0212] When the pulling force is lost, the tightening element 121 moves in the axial direction of the guide element 111 away from the adjusting element 151 under the action of the elastic element 141 .

[0213] The advantage of the present invention is that the high-pressure hose can be tensioned and adjusted by using the cooperation between the guide unit, the tightening unit and the elastic unit, so that the high-pressure hose and the hose reel always keep in contact, avoid slack, make the winding neat and improve safety; the adjustment unit, the first limit unit, the second limit unit and the locking unit can be used to adjust the movement range of the elastic unit between the tightening unit and the adjustment unit, so as to better adapt to the pulling force of the high-pressure hose when pulling the elastic unit, avoid the high-pressure hose from being torn due to excessive pulling, avoid the high-pressure air pipe from being loose in the hose reel due to insufficient pulling, and improve practicality.
