Description

Technical Field

[0001] This utility model relates to the field of papermaking equipment, and in particular to a transmission device for the steam head sleeve of a drying cylinder. Background Technology

[0002] In papermaking, the drying cylinder is a crucial component of the paper machine, used to dry wet paper sheets. During operation, the drying cylinder is heated by introducing hot air or other heat media. The paper then adheres tightly to the rotating surface of the drying cylinder, and the moisture gradually evaporates under the heat, thus drying the paper. A steam inlet is located at one end of the drying cylinder, blowing hot air into the cylinder to rapidly dry the paper. A siphon tube is also installed inside the drying cylinder to remove condensate generated during the cooling of the hot air. The siphon tube, drying cylinder, and steam inlet are connected by rotating joints, friction blocks, and other structural components.

[0003] In actual production, the surface of the drying cylinder is required to be very smooth to ensure that the paper is not damaged during the drying process. Therefore, a Teflon coating is sprayed onto the cylinder surface. During production, pulp and impurities come into contact with and rub against the drying cylinder surface, causing wear and affecting paper quality. Consequently, the drying cylinder coating needs to be reapplied during maintenance.

[0004] During the respraying process, the steam head and siphon pipe need to be removed. The aforementioned rotary joint is very inconvenient to disassemble and assemble. In addition, the siphon pipe is fixed inside the drying cylinder by a bracket, so staff need to enter the drying cylinder to remove it. The whole process is time-consuming and labor-intensive. Summary of the Invention

[0005] This invention addresses the problem of complex operations when removing the steam head and siphon pipe during the re-spraying of the drying cylinder by providing a transmission device for the steam head sleeve of the drying cylinder.

[0006] To solve the above problems, the technical solution adopted by this utility model is a transmission device for a drying cylinder steam head sleeve, including a sleeve body, which is a hollow tube. One end of the sleeve body is provided with a drive connecting plate, and the other end of the sleeve body is provided with a drying cylinder connecting plate with a siphon tube opening at its center for the siphon tube to pass through. A rotating connector is provided inside the sleeve body, and the rotating connector has a through hole at its center and is concentrically arranged with the sleeve body. This solution designs a sleeve structure, with one end connected to the drying cylinder and the other end connected to the drive device. While driving the drying cylinder to rotate, it covers the siphon tube and steam head inside the sleeve, preventing spraying onto the siphon tube and cylinder head during spraying, thus eliminating the need to remove them and greatly simplifying the drying cylinder maintenance and spraying process.

[0007] As a preferred implementation of the drying cylinder steam head sleeve transmission device, the rotating connecting member is located at one end of the sleeve body near the drive connecting plate.

[0008] As a preferred implementation of the steam head sleeve transmission device for the drying cylinder, the rotating connecting component is a bearing, and the end of the sleeve body is provided with a bearing mounting plate. The bearing mounting plate has a mounting hole that matches the outer diameter of the bearing. The bearing is installed in the mounting hole, and the inner ring of the bearing is used to connect the siphon pipe.

[0009] In a preferred embodiment of the drying cylinder steam head sleeve transmission device, the bearing end face facing the inside of the sleeve body is provided with a bearing seal to prevent moisture from entering the bearing and damaging the bearing lubrication.

[0010] As a preferred implementation of the steam head sleeve transmission device for the drying cylinder, a retaining ring is also provided in the mounting hole, which abuts against the end face of the bearing facing the outside of the sleeve body. This fixes the bearing position and prevents the bearing from falling off.

[0011] As a preferred embodiment of the drying cylinder steam head sleeve transmission device, the drive connecting plate has multiple drive connecting plate threaded holes for connecting the drive device; the drying cylinder connecting plate has multiple drying cylinder connecting plate threaded holes for connecting the drying cylinder. This enhances the stability of the connection and facilitates the installation and maintenance of the equipment.

[0012] As can be seen from the above technical solutions, the advantages of this utility model are as follows: One end of the sheath structure can be connected to the drying cylinder, and the other end is connected to the drive device. During the rotation of the drying cylinder, the siphon tube and steam head are covered inside the sheath, avoiding direct spraying of paint onto the siphon tube and cylinder head during spraying. Therefore, it is not necessary to remove them before spraying, greatly simplifying the drying cylinder maintenance and spraying process. The rotating connector is set in the main body of the sheath near the drive connecting plate, which improves the transmission efficiency and makes the transmission of driving force more direct and efficient. The use of bearings as rotating connectors and the opening of mounting holes on the bearing mounting plate that are compatible with the outer diameter of the bearing not only reduces the coefficient of friction and wear, and extends the service life of the equipment, but also the bearing sealing design effectively prevents water vapor from entering the bearing, protects the lubrication state of the bearing, and ensures the normal operation of the equipment. The mounting hole is equipped with a retaining ring to fix the bearing position and prevent the bearing from falling off during operation, enhancing the reliability and safety of the equipment. The design of multiple threaded holes on the drive connecting plate and the drying cylinder connecting plate enhances the stability of the connection, facilitates the installation and maintenance of the equipment, and improves the overall ease of use of the device.
