Description

Technical Field

[0001] The utility model relates to the technical field of maintenance of cigarette processing equipment, in particular to a quick disassembly and replacement tool for a rotary joint of a German Hauni-kld tobacco drying machine. Background Art

[0002] The tobacco drying machine equipment is mainly composed of the main components such as drying cylinder, bracket, transmission device, steam pipeline system, compressed air pipeline system, hot air system, front chamber, and rear chamber. The drying cylinder is the main working part of the drying machine, which is composed of a rotary joint, a steam inlet ring pipe, a steam outlet ring pipe, a roller, a large gear, etc.; its function is to provide and conduct heat to realize the transportation of materials. The tobacco in the drying cylinder is heated by the thin plate heating device and the hot air entering the drying cylinder at the same time. During the heating process, the water evaporated from the tobacco is discharged from the moisture outlet at the discharge end of the drying cylinder. The rotary joint is the main component of the steam pipeline system of the drying machine. Its function is to send steam from the static pipeline to each heat exchange plate of the rotating drying cylinder through the air inlet ring pipe. After heat exchange, the condensed water is collected to the rotary joint through the air outlet ring pipe and led out.

[0003] At present, the method for replacing the rotary joint of the silk drying machine is to place the rotary joint on a pallet and lift the pallet with a forklift for installation. Due to the heavy weight and large size of the rotary joint, it is difficult to adjust during installation, and the installation space is small, the installation is time-consuming and labor-intensive, and there are safety hazards.

[0004] In the prior art, as disclosed in patent application No. 201820788124.4 “A Rotary Joint Installation Tool for Silk-Drying Machine”, it includes a bracket, a fork frame and a connecting rod arranged between the fork frame and the bracket. The bracket is an unclosed “C”-shaped cylinder as a whole, with a through slot at its lower end. One end of the bracket is open and the other end is closed. A circular hole is arranged at the center of the closed end face of the bracket. A push screw is axially passed through the circular hole and fixedly connected by a nut. The fork frame is fixed to the bracket by a connecting rod, and a wedge block is arranged inside the fork frame. However, when installing the rotary joint, the device cannot rotate and adjust the rotary joint, and the rotary joint is not fixed, which poses a hidden danger. Utility Model Content

In this embodiment, the German Hauni-kld silk drying machine is taken as an example. The rotary joint of this model of silk drying machine weighs 150Kg. It needs to be locked and fixed with a locking sleeve during installation, otherwise there will be hidden dangers.

[0033] Specific working principle:

[0034] 1. First, install the rotary joint of the German Hauni-kld tofu drying machine in the overall frame and lock it with a locking sleeve;

[0035] 2. After installation, insert the forklift fork into the bottom beam and lock it;

[0036] 3. Lift the forklift fork until the parallel line of the flange of the positioning distributor of the tofu drying machine overlaps with it;

[0037] 4. Use the point contact of the bull's eye bolt to rotate and fine-tune the axial adjustment bolt to align it with the locating pin hole of the locating distributor flange;

[0038] 5. Now that the two lines are in place, rotate the axial bull's eye bolt clockwise (the point contact friction is small) to push the rotary joint into combination with the positioning distributor flange, and install the flange fixing bolts.

[0039] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
