Description

Technical Field

[0001] The invention relates to a high-efficiency drying cylinder for fabric drying, belonging to the technical field of printing and dyeing equipment. Background Art

[0002] Many processes in the printing and dyeing production process require drying drums to achieve flat-width drying. The flat-width wet fabric is tightly attached to the rotating hot drum surface at a certain wrap angle. During the operation, the heat energy conducted by the drum surface is absorbed to vaporize the water to achieve drying of the fabric. The water vapor in the drum will form condensed water after heat conduction and cooling. The condensed water will form a water film on the inner surface of the drying drum as the drying drum rotates at high speed, affecting the heat conduction. For this reason, a turbulator to prevent the formation of a uniform water film and a siphon device to discharge the condensed water will be installed in the drying drum. The existing siphon device includes a siphon tube extended into the drying drum. In order to prevent scratches on the drum wall, there will be a certain gap between the siphon tube and the inner wall of the drying drum, making it impossible to effectively and quickly discharge the condensed water, affecting the drying effect.

It includes a siphon tube 9 extending into the cylinder 3 through the hollow shaft 1, the siphon tube 9 is a movable siphon tube rotating together with the cylinder 2, the spoiler rod 5 is provided with a branch pipe 10 connecting the drainage channel 6 with the siphon tube 9 at the end plate end, the spoiler rod 5 is separated by the spoiler rod 5, the uniform water film cannot be formed when the drying cylinder rotates, and the condensed water gathers toward the spoiler rod 5 under the action of centrifugal force and enters the drainage channel 6 through the inlet, otherwise it will be scattered due to the loss of centrifugal force, and there is no gap between the inlet, the drainage channel 6 and the inner wall of the cylinder 2. Once there is condensed water on the inner wall of the cylinder, it will enter the drainage channel 6 through the inlet and be quickly discharged, and the inward folded edge can further prevent the condensed water entering the drainage channel 6 from escaping, thereby realizing the rapid and complete discharge of the condensed water.

[0021] As a preferred embodiment, the spoiler rod 5 is obliquely arranged on the outer edge of the connecting ring 4, and is provided with a branch pipe 10 end located behind the other end. When the drying cylinder 7 rotates along the needle, the spoiler rod 5 with the branch pipe end is located at the ten o'clock direction, and the other end is located at the twelve o'clock direction. The obliquely arranged spoiler rods 5 distributed along the circumference further prevent the condensed water from forming a uniform water film on the one hand, and on the other hand, the condensed water entering the drainage channel 6 of the spoiler rod 5 will be guided from away from the branch pipe end to the end with the branch pipe 10 under the action of centrifugal force, which is further conducive to the discharge of the condensed water.

[0022] As a preferred embodiment, the connecting ring 4 is an elastic ring with an opening on the circumference, and an inner folding flange 12 is provided at the opening of the elastic ring. A corresponding right-angle diverter 13 is provided at the opening of each connecting ring 4. The right-angle diverter 13 has an output shaft 14 and an input shaft 15 extending through its two ends at right angles. The two ends of the output shaft 14 are respectively spirally connected to the inner folding flanges 12 on both sides of the opening. The input shafts 15 of several right-angle diverters 13 are located on the same axis and connected in sequence. The synchronous transmission of multiple right-angle diverters 13 realizes the synchronous contraction and expansion of multiple connecting rings 4 on the turbulator. Before being placed in the cylinder 2, the right-angle diverter 13 is synchronously driven to shrink the opening of the elastic ring inward. The diameter of the turbulator 3 is made smaller than the inner diameter of the cylinder 2, so that the turbulator 3 can be easily placed in the cylinder 2. Then, the input shaft 14 is operated to synchronously expand the multiple elastic rings, so that the spoiler rod 5 on the elastic ring is in contact with the inner wall of the cylinder 2 and is tightened. The branch pipe 10 between the spoiler rod 5 and the siphon tube 9 is connected and installed, and the end plates and the hollow shaft 1 are installed at both ends of the cylinder 2. Since the multiple right-angle diverters 13 are synchronously driven, it is only necessary to operate the right-angle diverter 13 close to the end of the cylinder 2 during installation. The installer does not need to enter the cylinder 2, which is convenient for installation. In addition, the connecting ring 4 is synchronously expanded to evenly expand the turbulator 3, and the force is evenly distributed, which is conducive to the installation of the turbulator 3.

[0023] As a preference, at least one right-angle steering gear 13 is provided with a fastener for fixing the input shaft 15. During operation, the input shaft 15 of the right-angle steering gear 13 close to the end of the cylinder 2 can be rotated to achieve synchronous transmission of multiple right-angle steering gears 13. The fastening screw 11 can be screwed on the right-angle steering gear 13 close to the end. After the turbulator is expanded and installed by rotating the input shaft 15 of the right-angle steering gear 13 close to the end of the cylinder 2, the fastening screw 11 is tightened to fix the input shaft 15 to prevent it from rotating and prevent it from loosening during use.

The lubricating oil first enters the annular groove 20 and then enters between the outer ring and the inner ring through the through hole and then flows into the oil storage tank 21 of the shaft seal 19 on both sides through the refueling hole 25. The lip 24 contacts the hollow shaft 1 to achieve sealing. The structure of the shaft seal assembly 19 in which the inner shaft seal 22 and the outer shaft seal 23 cooperate with each other can enhance the sealing performance on the one hand, and on the other hand, an oil storage tank 21 can be formed between the outer shaft seal 23 and the lip 24 of the inner shaft seal 22. The oil storage tank 21 is connected to the cavity 8. When lubricating oil is added to the bearing shaft 18 in the bearing seat through the refueling nozzle 17, the lubricating oil can be automatically replenished into the oil storage tank 21 of the shaft seal assembly 19, so that the shaft seal assembly 19 can be kept in a state of being full of lubricating oil for use, thereby reducing wear and extending the service life.

[0025] As a preferred embodiment, a valve membrane 26 is provided at the filling hole 25. The valve membrane 26 is made of rubber and plays a one-way blocking role. When lubricating oil is added to the cavity 8, the valve membrane 26 is lifted up, and the lubricating oil can be automatically added to the oil storage tank 21 through the filling hole 25. Then the valve membrane 26 blocks the filling hole 25, and the lubricating oil in the oil storage tank 21 cannot flow back to the cavity 8, so that the shaft seal assembly 19 is kept full of lubricating oil. When the bearing shaft 18 is filled with lubricating oil, the shaft seal assembly 19 can also be supplemented with lubricating oil.
