Description

Technical Field

[0001] This utility model relates to the field of toilet paper processing technology, and more specifically, to a toilet paper pulping and filtering mechanism. Background Technology

[0002] Toilet paper is mainly used for daily hygiene and is one of the indispensable types of paper for the general public. There are many raw materials for making toilet paper, commonly including natural and pollution-free raw materials such as cotton pulp, wood pulp, bamboo pulp, and straw pulp. In the process of toilet paper processing, the pulp needs to be filtered and screened to remove larger plant fibers and impurities. Therefore, a toilet paper pulp filtration mechanism is needed.

[0003] The prior art discloses a pulp filtration and screening device for clean papermaking, application number CN202021225819.5. This invention uses a filter screen to filter and intercept large fibers and impurities in the pulp. A stepper motor drives a lead screw to rotate, which in turn drives a cleaning plate and brush to clean the filtered large fibers and impurities. Finally, the pulp is discharged through the cleaning port. However, opening the cleaning port requires the user to stop feeding pulp for a considerable period, which affects the device's efficiency. Furthermore, the lead screw is prone to clogging and malfunction in the pulp filtration environment, making its practicality somewhat limited. To address these shortcomings, those skilled in the art have proposed a toilet paper pulp filtration mechanism. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a toilet paper pulping and filtering mechanism that can automatically clean up debris intercepted on the filter screen without prolonged downtime. This results in higher work efficiency, greater reliability, less malfunction, and enhanced practicality, thereby solving the problems mentioned in the background technology.

[0005] To achieve the advantages of automatic cleaning of debris intercepted on the filter screen without prolonged downtime, resulting in higher work efficiency, greater reliability, less malfunction, and enhanced practicality, the specific technical solution adopted by this utility model is as follows: A toilet paper pulping and filtering mechanism includes a pulp tank, a filter half-cylinder, and a scraper. A support block is fixedly installed on the inner wall of the pulp tank. A filter screen is fixedly installed on the arc-shaped bottom surface of the filter half-cylinder, which is placed on the support block. Mounting plates are symmetrically fixedly installed on the pulp tank. A rotating shaft is installed between the two mounting plates, and one end of the rotating shaft is connected to the output end of a servo motor. Mounting blocks are symmetrically fixedly installed on the rotating shaft, and mounting grooves are provided on the mounting blocks. Mounting connecting rods are symmetrically welded to the bottom surface of the scraper and inserted into the mounting grooves. A cleaning port is provided on one side wall of the pulp tank. A placement plate is fixedly installed on one side wall of the pulp tank, and a collection box is placed on the placement plate.

[0006] Furthermore, several return springs are installed on one side wall of the mounting groove, and a locking pin is connected to the movable end of the return spring. A pull rod is fixedly connected to one side of the locking pin, and a locking hole is opened on one side of the mounting rod.

[0007] Furthermore, mounting screw holes are correspondingly opened at the four corners of the filter slurry half-cylinder and on the support block, and mounting bolts are screwed into the mounting screw holes.

[0008] Furthermore, several pulp inlet pipes are provided above the pulp tank, and pulp inlet valves are installed on the pulp inlet pipes. A pulp discharge pipe is connected to one side of the bottom of the pulp tank, and a pulp discharge valve is installed on the pulp discharge pipe.

[0009] Furthermore, a control panel is fixedly installed on the side wall of the pulp tank, and the control panel is electrically connected to the servo motor, the pulp inlet valve, and the pulp outlet valve.

[0010] Furthermore, the top of the scraper plate abuts against the inner wall of the filter screen.

[0011] Furthermore, the height of the top surface of the filter slurry half-cylinder is higher than the height of the bottom surface of the cleaning port.

[0012] Compared with the prior art, the present invention provides a toilet paper pulping and filtering mechanism, which has the following beneficial effects:

[0013] (1) This utility model is provided with a pulp tank, a filter half-cylinder, and a scraper. A support block is fixedly installed on the inner wall of the pulp tank, and a filter screen is fixedly installed on the arc-shaped bottom surface of the filter half-cylinder. The four corners of the filter half-cylinder and the support block are respectively provided with mounting screw holes, so the filter half-cylinder can be placed on the support block and then fixed by mounting bolts. Mounting plates are symmetrically fixedly installed on the pulp tank, and a rotating shaft is installed between the two mounting plates. One end of the rotating shaft is connected to the output end of a servo motor. Mounting blocks are symmetrically fixedly installed on the rotating shaft, and mounting grooves are provided on the mounting blocks. Mounting connecting rods are symmetrically welded to the bottom surface of the scraper. During installation... The mounting rod can be inserted into the mounting slot. Several return springs are installed on one side wall of the mounting slot, and the movable end of the return spring is connected to a locking pin. When the mounting rod is inserted into the mounting slot, the spring force of the return spring can push the locking pin into the locking hole opened on the mounting rod, thus fixing the mounting rod on the mounting block. This allows the scraper to rotate using the rotating shaft. When the scraper is severely worn, the user only needs to pull the pull rod connected to the locking pin to disengage the locking pin from the locking hole, thus disassembling the scraper and the mounting rod. The operation is simple and convenient, facilitating subsequent maintenance and replacement, and making it more practical.

[0014] (2) This utility model is equipped with a pulp tank, a filter half-cylinder, and a scraper. As described above, after installing the filter half-cylinder and the scraper, the user can open the inlet valve installed on the inlet pipe through the control panel, so that the shredded pulp is introduced into the inner cavity of the filter half-cylinder through the inlet pipe, and large particles of fiber and impurities contained in the shredded pulp are removed by the filter screen. The qualified pulp obtained can be discharged and collected by opening the discharge valve installed on the discharge pipe. As filtration proceeds, a certain amount of large particles of fiber and impurities will be blocked on the filter screen. At this time, the user can temporarily close the inlet valve and start the servo motor to drive the rotating shaft to rotate 360 ​​degrees. The scraper will then rotate 360 ​​degrees and use the scraper to remove impurities. The scraper can scrape the impurities clogging the inside of the filter screen to the cleaning port on one side wall of the pulp tank. A placement plate is fixedly installed on the outer wall of one side of the pulp tank, and a collection box can be placed on the placement plate. So the scraped pulp impurities can slide down the cleaning port into the collection box for collection. The worker only needs to replace and clean the collection box later. The operation is simpler and more convenient. After the scraper rotates one revolution and resets, the control panel can continue to open the pulp inlet valve to feed the pulp, so as to continue filtering and removing impurities. Thus, the impurities intercepted on the filter screen can be automatically cleaned without long-term machine downtime. The work efficiency is higher, the use is more reliable, less prone to failure, and more practical. Attached Figure Description

[0032] Working Principle: This utility model includes a pulp tank 1, a filter cylinder 6, and a scraper 13. A support block 18 is fixedly installed on the inner wall of the pulp tank 1. A filter screen 7 is fixedly installed on the arc-shaped bottom surface of the filter cylinder 6. Mounting screw holes 25 are correspondingly provided at the four corners of the filter cylinder 6 and on the support block 18, allowing the filter cylinder 6 to be placed on the support block 18 and then fixed in place using mounting bolts 19. Mounting plates 11 are symmetrically fixedly installed on the pulp tank 1. A rotating shaft 12 is installed between the two mounting plates 11, and one end of the rotating shaft 12 is connected to the output end of a servo motor 3.

The resulting qualified pulp can be discharged and collected by opening the discharge valve 10 installed on the discharge pipe 9. As filtration progresses, a certain amount of large particles of fiber and impurities will become clogged on the filter screen 7. At this time, the user can temporarily close the inlet valve 14 and simultaneously start the servo motor 3 to rotate the rotating shaft 12 360 degrees, thus removing the scraper 13. 3. The filter screen 7 is rotated 360 degrees, and the scraper 13 scrapes the impurities clogging the inside of the filter screen 7 to the cleaning port 8 on one side wall of the pulp tank 1. A placement plate 15 is fixedly installed on the outer wall of one side of the pulp tank 1, and a collection box 16 can be placed on the placement plate 15. Therefore, the scraped pulp impurities can slide down the cleaning port 8 into the collection box 16 for collection.
