Description

Technical Field

[0001] The utility model relates to the technical field of papermaking machines, in particular to a papermaking pressing and dehydrating mechanism. Background Art

[0002] A papermaking machine is a machine that makes paper from a water-suspension of pulp that meets the requirements of papermaking through processes such as filter dehydration, mechanical extrusion dehydration and drying. A papermaking machine includes three main parts that complete the above process: forming, pressing and drying, and is equipped with necessary finishing, winding and transmission devices, as well as auxiliary systems such as pulp supply, pulp and white water circulation, vacuum, ventilation and exhaust, damaged paper handling and lubrication, and automatic control.

[0003] Please refer to the patent for a paper machine squeezing and dehydrating mechanism with announcement number CN214401200U, in which it is proposed that "the existing squeezing and dehydrating mechanism is inconvenient to adjust the squeezing force for different papers when in use, and it is impossible to match the appropriate squeezing force for the thickness and material of different papers during dehydration. When squeezing, the debris on the pressure roller is easily adhered to the next paper when it rotates again, causing pollution to the paper"; in this patent, different squeezing forces can be adjusted according to different papers by using slide grooves, and slide grooves are provided on both sides of the main body. The slide groove is driven to move inside the slide groove by rotating the threaded rod at the top of the slide, so that the slide groove drives the rotating rod to move through the rotating shaft, so that the rotating rod is fitted in the arc groove on the side of the pressure plate, and the appropriate squeezing force can be matched for different papers, which is convenient for dehydrating the paper.

[0004] Although the above patent adjusts different pressing forces according to different papers, the distance between the two horizontal bars that move the paper cannot be adjusted. When the thickness or material of the paper changes, the pulling effect on the paper will change, which will cause the paper to be unable to move and the paper to be damaged. It has certain limitations when used, and the contact area between the pressure plate and the paper is large. When the rotating rod cooperates with the pressure plate to press the paper, the paper is easily damaged due to friction with the pressure plate when it moves. In view of this, the present application proposes a papermaking pressing and dehydration mechanism. Utility Model Content

[0025] Embodiment 1: The pressing adjustment mechanism includes a conveying motor 5 fixedly connected to the front of the mounting frame 1. The left and right sides of the mounting frame 1 are fixedly connected with mounting blocks 102, so that the mounting frame 1 can be conveniently fixed on the papermaking machine by using the provided mounting blocks 102. The mounting frame 1 is U-shaped, so that the paper belt 10 can be conveniently moved inside the mounting frame 1. The output end of the conveying motor 5 is fixedly connected with a driving roller 2. The inside of the mounting frame 1 is rotatably connected with a plurality of driven rollers 3, and a conveyor belt 4 is sleeved on the outside of the driving roller 2 and the driven roller 3.

[0026] Among them, the inside of the installation frame 1 is movably connected with a pressure roller 6 corresponding to the position of the conveyor belt 4, and the driving roller 2 and a plurality of driven rollers 3 are evenly arranged in an arc trajectory, so that the shape of the conveyor belt 4 can be easily adapted to the pressure roller 6. The top of the installation frame 1 is rotatably connected with a guide roller 101 for guiding the paper tape 10, so that the set guide roller 101 can be used to guide the paper tape 10 to move toward the inside of the installation frame 1. A pressing adjustment component for adjusting the position of the pressure roller 6 is arranged inside the installation frame 1.

[0027] In this embodiment, the pressing adjustment assembly includes a first rotating block 8 fixedly connected to the front and rear sides of the mounting frame 1. The first rotating block 8 is internally rotatably connected to a first screw rod 9. The outer side of the first screw rod 9 is threadedly connected to a first shift block 7 rotatably connected to the pressure roller 6, so that the first shift block 7 can drive the pressure roller 6 to move toward or away from the conveyor belt 4 as the first screw rod 9 rotates.

[0028] Among them, the interior of the installation frame 1 is rotatably connected with the conveying roller 11 and the pressure rod 12 located on the upper and lower sides of the paper belt 10, and the interior of the installation frame 1 is provided with a transmission component for linking the conveying roller 11 and the driven roller 3. The transmission component includes a sprocket 13 fixedly connected to the conveyor belt 4 and the front of the driven roller 3. The outer sides of the two sprockets 13 are provided with chains 14, so that the conveying roller 11 and the driven roller 3 can be linked by using the set chain transmission structure.

[0029] In this embodiment, a shift adjustment component for adjusting the position of the pressure rod 12 is provided inside the installation frame 1, and the shift adjustment component includes a second rotating block 16 fixedly connected to the front and rear sides of the installation frame 1, and the internal thread of the second rotating block 16 is connected to the second screw 17, and the bottom end of the second screw 17 is fixedly connected to the second shift block 15 rotatably connected to the pressure rod 12, so that the second shift block 15 can drive the pressure rod 12 to move up and down as the second screw 17 rotates.

[0030] It should be noted that the papermaking pressing and dehydrating mechanism, through the setting of the pressing adjustment mechanism, can make the pressing roller 6 squeeze the paper tape 10 toward the conveyor belt 4, so as to achieve the pressing and dehydration of the paper tape 10. During this process, the conveyor belt 4 and the conveyor roller 11 can rotate synchronously, so as to apply a stable and continuous pulling effect to the paper tape 10, improve the movement stability of the paper tape 10, and reduce the risk of damage to the paper tape 10 due to excessive friction. When the thickness and material of the paper tape 10 change, the position of the pressing roller 6 and the pressure rod 12 can be adjusted as needed, so that while ensuring the good pressing and dehydration effect, the gap between the conveyor roller 11 and the pressure rod 12 is suitable for different types of paper tapes 10, so as to further improve the movement stability of the paper tape 10 and effectively enhance the practicality of the device.

[0031] Embodiment 2: The cleaning component includes a collection frame 19 fixedly connected to the inside of the mounting frame 1, and an upper scraper 20 is fixedly connected to the inner bottom wall of the collection frame 19, so that the upper scraper 20 can scrape off impurities on the upper surface of the paper tape 10 and store the impurities in the collection frame 19. A plurality of water-permeable holes 1901 are provided at the bottom of the collection frame 19, so that the liquid entering the collection frame 19 along with the impurities can flow downward through the water-permeable holes 1901.

[0032] Among them, the installation frame 1 is fixedly connected to the inside with a lower scraper 18, which facilitates the lower scraper 18 to scrape off impurities on the lower surface of the paper tape 10.

[0033] It should be noted that the papermaking pressing and dewatering mechanism, through the cleaning component, the upper scraper 20 and the lower scraper 18 can respectively scrape off the impurities on the upper and lower surfaces of the paper belt 10, and utilize the collecting frame 19 and the water collecting frame 21 to collect the impurities, so as to maintain a good cleaning effect, prevent impurities from contaminating other papers, and effectively improve the practicability of the device.

[0034] The working principle of the above embodiment is:

[0035] When the papermaking pressing and dewatering mechanism is used, the mounting frame 1 needs to be fixed on the papermaking machine by using the mounting block 102, and the paper tape 10 outputted from the papermaking machine is pulled to the mounting frame 1 through the guide roller 101, and then the first screw 9 and the second screw 17 need to be rotated according to the thickness and material of the paper tape 10, so that the first shift block 7 drives the pressing roller 6 to move away from or close to the conveyor belt 4 as the first screw 9 rotates, so as to facilitate maintaining a good pressing and dewatering effect;

[0036] The second shift block 15 drives the pressure rod 12 to move up and down as the second screw 17 rotates, so that the pressure rod 12 cooperates with the conveying roller 11 to clamp the paper belt 10. After that, the conveying motor 5 only needs to be operated to rotate the conveying belt 4. The conveying roller 11 can be rotated synchronously with the conveying belt 4 using a chain transmission structure, so as to maintain a stable and continuous conveying effect, thereby facilitating continuous squeezing and dehydration of the paper belt 10.

[0037] During this process, the lower scraper 18 can scrape off impurities on the lower surface of the paper tape 10, and use the water collecting frame 21 to collect impurities and waste water falling into the paper tape 10, and the filter plate 22 can realize solid-liquid separation; and the upper scraper 20 can scrape off impurities on the upper surface of the paper tape 10, and store the impurities in the collecting frame 19, so as to facilitate the collection of impurities on the paper tape 10 and facilitate subsequent centralized processing.
