Description

Technical Field

[0001] The utility model relates to the technical field of shoe press rollers, in particular to an improved device for shoe press paired rollers. Background Art

[0002] In the papermaking industry, paper sheets still contain a large amount of moisture after being formed on the wire. Generally, the wet paper sheets must be dehydrated before being sent to the dryer. If they are sent directly to the dryer without pre-dehydration, a large amount of steam will be consumed, and the resulting paper sheets will have low density, rough surface, and low strength. Therefore, a shoe press device is needed to squeeze out the moisture on the paper to achieve the dehydration effect.

[0003] According to Chinese patent publication number CN217127869U, a shoe-type press roll for papermaking dewatering includes a support frame, a bottom press roll rotatably mounted below the support frame, and a drive wheel fixedly mounted at one end of the bottom press roll. A chute is provided above the support frame, and a slide is slidably mounted within the chute. A top press roll rotatably mounted within the slide, and a grid pattern is uniformly distributed on the top press roll. The utility model is provided with a mounting frame that cooperates with a feed wheel, allowing paper to be fed while the press wheel is dewatering the paper, thereby increasing the functionality of the press wheel and improving its practicality. A scraper is provided that cooperates with a recovery box.

[0004] The boot-type pressing roller in this announcement number can squeeze and dehydrate the paper through the cooperation of the top pressing roller and the bottom pressing roller, and can scrape and collect the paper scraps attached to the surface of the pressing roller through the cooperation of the scraper and the recycling box. Therefore, the scraper needs to be in contact with the roller surface. The scraper scrapes off the impurities on the surface during the rotation of the pressing roller, but the scraper is relatively sharp and can easily cause certain wear to the roller surface, thereby easily damaging the roller surface.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 5 In this embodiment, an improved device for a boot pressure pairing roller includes a support frame 1, a boot pressure roller 2 is provided on the support frame 1, a boot pressure back roller 3 is provided on the support frame 1 and is located below the boot pressure roller 2, an adjusting member 7 is provided on the side wall of the support frame 1, a fixing rod 8 is provided between the adjusting members 7 on both sides, a splash guard 5 is provided on the side of the fixing rod 8 close to the boot pressure back roller 3, a buffer member 9 is provided on the inner wall of the splash guard 5, a mounting plate 10 is provided on the buffer member 9, a cleaning cotton block 11 is provided inside the mounting plate 10, a water collecting hopper 4 is provided on the inner wall of the support frame 1 and is located below the boot pressure back roller 3, and the splash guard 5 is an arc-shaped plate.

[0025] Among them, the shoe pressure roller 2 and the shoe pressure back roller 3 are used together to squeeze the moisture in the paper being conveyed, and the side wall of the support frame 1 is provided with a driving mechanism, which includes a motor, a transmission wheel and a transmission belt. The transmission wheel is arranged on the shaft of the shoe pressure back roller 3, and the transmission belt is arranged on the two transmission wheels. The motor can drive the shoe pressure back roller 3 to rotate.

[0026] The adjusting member 7 includes a fixing plate 71, which is mounted on the side wall of the support frame 1. The side wall of the fixing plate 71 is provided with a threaded column 74. The outside of the fixing plate 71 is slidably connected to a U-shaped plate 72. An adjusting groove 73 is provided on one side of the U-shaped plate 72. The threaded column 74 is located inside the adjusting groove 73. The external thread of the threaded column 74 is connected to a nut 75 that is tightly pressed against the side wall of the U-shaped plate 72.

[0027] By loosening the nut 75, the U-shaped plate 72 can be moved forward or backward to adjust the distance between the cleaning cotton piece 11 and the shoe pressure back roller 3, thereby facilitating the adjustment of the pressure of the cleaning cotton piece 11 on the roller surface.

[0028] The buffer member 9 includes an outer cylinder 91, which is installed on the side of the splash plate 5 close to the boot pressure back roller 3. A spring 92 is provided inside the outer cylinder 91, and a movable rod 93 is provided on one side of the spring 92. The end of the movable rod 93 away from the spring 92 passes through the outer cylinder 91 and is fixedly connected to the mounting plate 10.

[0029] By setting the buffer part 9, the mounting plate 10 can be moved back and forth under the elastic action of the spring 92 itself, thereby avoiding hard contact between the mounting plate 10 and the shoe pressure back roller 3. When the shoe pressure back roller 3 rotates, the cleaning cotton block 11 can clean the impurities on the roller surface of the shoe pressure back roller 3 without causing damage to the roller surface.

[0030] See also Figure 2 、 Figure 3 In this embodiment, a card slot 12 is opened inside the mounting plate 10, and a card plate 15 is clamped inside the card slot 12. The cleaning cotton block 11 is arranged on the side wall of the card plate 15. The card slot 12 is a "T"-shaped slot. The side of the cleaning cotton block 11 away from the card plate 15 extends to the outside through the card slot 12. The side wall of the mounting plate 10 is rotatably connected to a blocking rod 13. The side wall of the mounting plate 10 is provided with a limiting column 14. The side wall of the blocking rod 13 is opened with a U-shaped groove, and the limiting column 14 is clamped inside the U-shaped groove.

[0031] It can be understood that the blocking rod 13 serves to limit the card plate 15 . When the card plate 15 needs to be pulled out from the card slot 12 , the blocking rod 13 can be rotated to move away from the side wall of the card plate 15 .

[0032] See also Figure 1 In this embodiment, the fixing rod 8 is arranged between the two U-shaped plates 72, and the mounting plate 10 and the cleaning cotton block 11 are both arc-shaped structures.

[0033] It should be noted that by setting the cleaning cotton piece 11 and the mounting plate 10 to be arc-shaped, the cleaning cotton piece 11 can fit the roller surface more closely.

[0034] The working principle of the above embodiment is as follows: when in use, the setting of the buffer part 9 can make the mounting plate 10 move back and forth under the elastic action of the spring 92 itself, thereby avoiding hard contact between the mounting plate 10 and the boot pressure back roller 3, and the cleaning cotton block 11 can clean the impurities on the roller surface of the boot pressure back roller 3 when the boot pressure back roller 3 rotates, without causing damage to the roller surface, and the setting of the adjusting part can adjust the distance between the cleaning cotton block 11 and the boot pressure back roller 3 by loosening the nut 75 and moving the U-shaped plate 72 to slide, thereby facilitating the adjustment of the pressure of the cleaning cotton block 11 on the roller surface, and if the cleaning cotton block 11 needs to be replaced or cleaned later, the stop rod 13 is rotated upward to move the limit column 14 out of the U-shaped groove, and the stop rod 13 is moved away from the side wall of the card plate 15, so that the card plate 15 can be pulled out of the card slot 12, thereby facilitating the replacement or cleaning of the cleaning cotton block 11.
