Description

Technical Field

[0001] The invention belongs to the technical field of shoe-pressing in a press section of a high-speed paper machine, and in particular relates to a self-adjusting shoe roller device and a use method thereof. Background Art

[0002] The main component of the shoe press is the shoe roller. When the shoe roller is working, the shoe cover is stretched at both ends. The two ends of the shoe cover that contacts the back roller are repeatedly subjected to alternating stresses such as pulling, pressing, and folding, which damages the shoe cover. In order to extend the life of the shoe cover, the shoe cover is generally moved a certain distance after one week of use to move the stress point of the shoe cover to reduce the damage to the shoe cover.

[0003] The traditional adjustment structure evenly installs several studs in the circumference between the transmission side support and the transmission side boot sleeve clamp, engraves scale lines on the support, installs a pointer on the transmission side boot sleeve clamping device, and adjusts the studs to allow the boot sleeve to move. The moving distance is determined according to the pointer and scale lines. This adjustment structure has the following problems when working: first, it is difficult to ensure that the circumferential adjustment studs are evenly stressed on the circumference of the boot sleeve clamping device during adjustment, resulting in damage to the studs; second, the adjustment time is long, which prolongs the downtime; finally, the adjustment studs between the boot sleeve clamping device and the support are unevenly adjusted when the boot sleeve moves, causing uneven axial force on the circumference of the boot sleeve clamping device, poor boot sleeve clamping and sliding, and accelerated wear. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a self-adjusting shoe roller device and a method for using the same.

A fixing frame 2 is provided at the other end of the inner wall of the shoe beam, and one end of the interior of the fixing frame 2 is provided with one end of a tensioning spring 2, and the other end of the tensioning spring 2 is connected to one side of the transmission side sliding cover.

[0008] Furthermore, one end of the boot cover is connected to one side of the operating side sliding cover, and the other end of the boot cover is connected to one side of the transmission side sliding cover.

[0009] Furthermore, the boot cover is made of polyurethane.

[0010] Furthermore, an operation side displacement sensor is provided at one end of the inner wall of the shoe beam, and a transmission side displacement sensor is provided at the other end of the inner wall of the shoe beam.

[0011] The present invention also discloses a method for using the self-adjusting shoe roller device, which mainly comprises the following steps: Step 1: When the shoe roller runs for a period of time and the shoe cover needs to move to the operating side, the output end of the hydraulic cylinder 2 is retracted, the tensioning force of the tensioning spring 2 is reduced, the output end of the hydraulic cylinder 1 is extended, and the tensioning force of the tensioning spring 1 is increased, so that the operating side sliding cover and the transmission side sliding cover move to the operating side at the same time, and the operating side displacement sensor and the transmission side displacement sensor transmit the moving distance signal to the control terminal via Bluetooth; Step 2: When the boot needs to move toward the transmission side, the output end of the hydraulic cylinder 1 is retracted, the tension of the tension spring 1 is reduced, the output end of the hydraulic cylinder 2 is extended, and the tension of the tension spring 2 on the transmission side is increased, so that the operating side sliding cover and the transmission side sliding cover move toward the transmission side at the same time, and the operating side displacement sensor and the transmission side displacement sensor transmit the moving distance signal to the control terminal via Bluetooth; Step 3: Adjust the tension of the boot cover by adjusting hydraulic cylinder 1 and hydraulic cylinder 2 according to work needs to ensure the tension of the boot cover.
