Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of rapid drying cylinder technology, and more specifically, to a rapid drying cylinder for a tissue paper machine. Background Technology

[0002] The rapid drying cylinder of a toilet paper machine is a device used to quickly dry paper during the toilet paper production process. The rapid drying cylinder heats the surface of the cylinder through an internal heating device. When the wet paper passes through the drying cylinder, it comes into contact with the high-temperature cylinder surface, and the moisture is evaporated, thereby achieving rapid drying of the paper. It can quickly remove moisture from the paper in a short time.

[0003] Drying cylinders are usually made of metal. In humid or high-temperature working environments, the metal surface is prone to oxidation and rust formation. Especially when in contact with wet paper sheets, the frequent contact between the water on the wet paper sheets and oxygen in the air with the drying cylinder, and the condensation of water vapor caused by the surface temperature changes of the drying cylinder, will accelerate the formation of rust. When toilet paper is dried in the drying cylinder, it will cause the toilet paper to be contaminated with rust, affecting the quality and hygiene of the toilet paper. Utility Model Content

[0047] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0048] like Figures 1-4 As shown, a rapid drying cylinder of a toilet paper machine according to an embodiment of the present disclosure includes a base 1 and a cylinder 2. The cylinder 2 is mounted on the base 1 via a rotating mechanism. It also includes a scraper 3, a drive mechanism, and a rotating mechanism. The scraper 3 is located below the cylinder 2 and is used to scrape off rust from the surface of the cylinder 2. The drive mechanism is mounted on the base 1 and is used to drive the scraper 3 to scrape off the rust from the surface of the cylinder 2. The rotating mechanism is mounted on the drive mechanism and is used to drive the scraper 3 to rotate and approach the cylinder 2. The scraper 3 is semi-circular, and one end of the scraper 3 is a pointed surface. When the scraper 3 is horizontal with the base 1, the gap between the scraper 3 and the cylinder 2 is the movable area. After the pointed surface of the scraper 3 scrapes off the rust on the cylinder 2, it slides along the arc of the inner wall of the scraper 3 into the scraper 3.

[0049] When using a drying cylinder to dry toilet paper, the first step is to start the rotating mechanism, which drives the cylinder 2 to rotate. The rotating mechanism includes a rotating motor 16 and a rotating shaft 17. The rotating motor 16 is mounted on the outer wall of the base 1, and the rotating shaft 17 is coaxially and fixedly connected to the output end of the rotating motor 16. The cylinder 2 is fixedly connected to the outer wall of the rotating shaft 17. Start the rotating motor 16, which drives the rotating shaft 17 to rotate. Then the cylinder 2 will rotate with the rotating shaft 17. At this time, the toilet paper can be placed on the cylinder 2 and dried as the cylinder 2 rotates.

[0050] After the toilet paper is dried, the contact between moisture and oxygen with the cylinder 2 will cause the cylinder 2 to become damp and rusty. At this time, it is necessary to remove the rust from the cylinder 2. The drive mechanism includes a drive frame 4, a drive motor 5, a reciprocating screw 6, a screw nut 7, and a sliding component. The drive frame 4 is fixedly connected to the inner bottom wall of the base 1. The drive motor 5 is installed on the outer side wall of the drive frame 4. The reciprocating screw 6 is coaxially fixedly connected to the output end of the drive motor 5. The screw nut 7 is threadedly connected to the reciprocating screw 6. The sliding component is set on the inner bottom wall of the base 1. When the drive motor 5 is started, the reciprocating screw 6 is rotated by the drive motor 5. At this time, the screw nut 7 threadedly connected to the reciprocating screw 6 will begin to slide laterally. At this time, the sliding component will also move along with the sliding of the screw nut 7.

[0051] The sliding assembly includes a fixed frame 8, a smooth rod 9, a sliding block 10, and a connecting rod 11. The fixed frame 8 is fixedly connected to the inner bottom wall of the base 1. The smooth rod 9 is fixedly connected between the inner side walls on both sides of the fixed frame 8. The sliding block 10 is slidably fitted onto the outer wall of the smooth rod 9. The connecting rod 11 is fixedly connected between the lead screw nut 7 and the sliding block 10. The fixed frame 8 and the drive frame 4 are lower than the connecting rod 11. The lead screw nut 7 and the sliding block 10 are fixedly connected by the connecting rod 11. Then, when the lead screw nut 7 slides, it can synchronously drive the sliding block 10 to slide, which can make the sliding of the connecting rod 11 more stable.

[0052] Then, the rotating mechanism is started, which drives the scraper 3 to be adjusted to fit tightly against the outer wall of the cylinder 2. The rotating mechanism includes a rotating port 12, a forward and reverse motor 13, a rotating rod 14, and a connecting block 15. The rotating port 12 is opened on the side wall of the connecting rod 11. The forward and reverse motor 13 is installed on the outer side wall of the connecting rod 11. The rotating rod 14 is coaxially and fixedly connected to the output end of the forward and reverse motor 13. The connecting block 15 is fixedly connected to the outer wall of the rotating rod 14, and the scraper 3 is fixedly connected to the top of the connecting block 15. The rotating rod 14 is rotatably connected inside the rotating port 12, and the diameter of the rotating rod 14 is the same as the diameter of the rotating port 12. The forward and reverse motor 13 is started, which drives the rotating rod 14 to rotate. At this time, the scraper 3 will rotate with the rotating rod 14 to scrape the rust on the outer wall of the cylinder 2. The scraped rust will slide along the arc of the inner wall of the scraper 3 into the semi-circular scraper 3 for collection.

[0053] Working Principle: When using a drying cylinder to dry toilet paper, the rotating motor 16 is first started. The rotating motor 16 drives the rotating shaft 17 to rotate, and then the cylinder 2 rotates along with the shaft 17. At this time, the worker can place the toilet paper on the cylinder 2, and it will dry as the cylinder 2 rotates. After the toilet paper is dried, moisture and oxygen coming into contact with the cylinder 2 will cause it to become damp and rusty. The rust on the cylinder 2 needs to be removed. The forward and reverse rotating motor 13 is started, which drives the rotating rod 14 to rotate. The scraper 3 then rotates along with the rotating rod 14, scraping the rust on the outer wall of the cylinder 2. The pointed scraper 3 removes the rust, and the scraped rust will run along the inner wall of the scraper 3. The paper is collected by sliding in an arc into the semi-circular scraper 3. At this time, the drive motor 5 is started, which drives the reciprocating screw 6 to rotate. The screw nut 7, which is threaded onto the reciprocating screw 6, will start to slide laterally. The screw nut 7 is fixedly connected to the sliding block 10 by the connecting rod 11. Then, when the screw nut 7 slides, it will drive the sliding block 10 to slide synchronously. At this time, the screw nut 7 will drive the scraper 3 to scrape the outer wall of the cylinder 2 back and forth. After scraping, the forward and reverse motor 13 can drive the scraper 3 to rotate to one side to collect the rust collected inside. Then, the screw nut 7 drives the scraper 3 to move closer to the outer wall of one side of the base 1 to avoid interference and obstruction during the drying of the toilet paper.
