Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, and in particular to an adjustable support structure for a papermaking pressure roller. Background Technology

[0002] Papermaking technology is the process of making paper from cellulose and other fibrous materials through wet or dry processes. It is divided into two types: machine-made and hand-made. Machine-made papermaking is carried out continuously on a papermaking machine. Pulp suitable for paper quality is diluted with water to a certain concentration and initially dewatered in the wire section of the papermaking machine to form a wet sheet. It is then pressed to dewater and then dried to form paper. Hand-made papermaking uses a frame with bamboo screens, polyester mesh, or copper mesh to form a wet sheet of fibers that are dispersed and suspended in water. It is then pressed to dewater and then dried in the sun or oven to form paper. With the development of society, more and more people are adopting machine-made papermaking.

[0003] In mechanical papermaking, paper dewatering is an important process. Pressure is applied to the wet paper sheet using pressure rollers to squeeze out the water, thereby achieving the dewatering effect.

[0004] In real life, when dewatering wet paper sheets using pressure rollers, the pressure rollers and their connected support structures are mostly fixed, which means that the pressure rollers can only press paper within a fixed width range. When faced with the pressing needs of paper of different widths, the pressure rollers cannot be adjusted accordingly, thus limiting production flexibility. Therefore, an adjustable support structure for papermaking pressure rollers is needed. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable support structure for papermaking pressure rollers to solve the problems mentioned in the background art.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0043] Given that in the current technology, when dewatering wet paper sheets using pressure rollers, the pressure rollers and the support structure they are connected to are mostly fixed, which means that the pressure rollers can only press paper within a fixed width range. When faced with the pressing needs of paper of different widths, the pressure rollers cannot be adjusted accordingly, thus limiting production flexibility.

[0044] like Figure 1-4 As shown, this utility model embodiment provides an adjustable support structure for a papermaking pressure roller, comprising:

[0045] Support assembly 1, support assembly 1 includes:

[0046] First support 11;

[0047] There are two first supports 11, and their bottom ends are fixed on the frame of the paper machine dewatering process. The entire device is connected and supported by the first supports 11.

[0048] The outer wall of the connecting frame 12 is slidably disposed on the inner wall of the first bracket 11;

[0049] The second bracket 13 is fixedly mounted on the top of the connecting frame 12 on one side of its bottom end;

[0050] Adjustment component 2, adjustment component 2 includes:

[0051] The double-ended lead screw 21 has its outer wall penetrating one side of the second bracket 13;

[0052] The bidirectional lead screw 21 is connected to the second bracket 13 by a bearing;

[0053] A rotating knob 22 is fixedly mounted on one end of a bidirectional lead screw 21 on one side.

[0054] The outer wall of the knob 22 is provided with protective threads to increase the friction between the hand and the outer wall of the knob 22, making it easier to rotate the knob 22;

[0055] Connecting block 23, the inner wall thread of connecting block 23 is set on one side of the outer wall of the bidirectional lead screw 21;

[0056] The top end of the connecting plate 24 is fixedly mounted on the bottom end of the connecting block 23;

[0057] The pressure roller 3 has one end rotatably mounted on one side of the connecting plate 24, and the two coaxial pressure rollers 3 are slidably connected to each other.

[0058] The pressure roller 3 is used to press and dewater the wet paper sheet, and the two coaxial pressure rollers are always in contact with each other as the connecting block 23 moves on the bidirectional screw 21.

[0059] Furthermore, a through groove 18 is provided at the top of the second bracket 13, and one side of the through groove 18 is connected to the other end of the bidirectional lead screw 21 by a bearing.

[0060] Furthermore, the adjustment component 2 also includes:

[0061] A horizontal plate 25 is provided with a pressure roller 3 on one side of the horizontal plate 25;

[0062] The pressure roller 3 connected to the horizontal plate 25 can perform secondary pressing on the paper after it has been pressed by the pressure roller 3 connected to the connecting plate 24, thereby improving the paper dewatering effect.

[0063] Furthermore, a slider 4 is fixedly provided on the inner wall of the pressure roller 3, and the outer wall of the slider 4 is slidably connected to the inner wall of another pressure roller 3 on the same axis.

[0064] The inner wall of the pressure roller 3 on the other side of the coaxial axis is provided with a groove that matches the slider 4.

[0065] Furthermore, the bottom end of the outer wall of the pressure roller 3 is lower than the bottom ends of the horizontal plate 25 and the connecting plate 24, respectively;

[0066] Furthermore, the adjustment component 2 also includes:

[0067] The slide rod 26 has one end fixedly mounted on the other side of the horizontal plate 25, and a rod seat 17 is slidably mounted on the outer wall of the slide rod 26. One side of the rod seat 17 is fixedly mounted on one side of the first bracket 11.

[0068] The slide bar 26 can guide and limit the connecting plate 24 and the horizontal plate 25 to move horizontally. At the same time, the slide bar 26 can also provide auxiliary connection support for the horizontal plate 25, improve the overall stability of the pressure roller 3 and its connecting parts, and the slide bar 26 is always in contact with the rod seat 17 during the adjustment and movement of the connecting plate 24.

[0069] The working principle is as follows: First, according to the width of the wet paper sheet to be dehydrated, the knob 22 is rotated. The rotation of the knob 22 drives the bidirectional lead screw 21 to rotate. The rotation of the bidirectional lead screw 21 drives the two connecting plates 24 to move in opposite directions through the two connecting blocks 23. The opposite movement of the two connecting plates 24 drives the two coaxial pressure rollers 3 to move in opposite directions. Similarly, the opposite movement of the two connecting plates 24 drives the pressure rollers 3 connected to them to move in opposite directions through the two horizontal plates 25. In this way, the pressure rollers 3 can be adaptively adjusted according to the pressing requirements of different paper widths, thereby increasing production flexibility and ensuring the stability of pressing quality.

[0070] Specifically, such as Figure 1-4 As shown, the support assembly 1 also includes:

[0071] The locking bolt 15 has an outer wall thread set at the top of one side of the first bracket 11, and one end of the locking bolt 15 contacts one side of the connecting bracket 12. A scale line 14 is engraved on one side of the connecting bracket 12.

[0072] The locking bolt 15 is used to lock and fix the connecting frame 12 after the position is adjusted. The scale line 14 is used to precisely adjust the position of the pressure roller 3 up and down to adjust the contact pressure between the pressure roller 3 and the paper.

[0073] Furthermore, the support assembly 1 also includes:

[0074] The slide bar 16 is fixedly mounted on one side of the connecting frame 12, and the outer wall of the slide bar 16 is slidably connected to the inner wall of the first bracket 11.

[0075] The slide bar 16 is I-shaped and is used to limit the movement of the connecting frame 12 to prevent it from sliding out of the first bracket 11. The inner walls of the first bracket 11 are provided with fixing grooves that are compatible with the slide bar 16 on both sides, and the narrow side end of the slide bar 16 passes through the top of the fixing groove to the top of the first bracket 11.

[0076] The working principle is as follows: After adjusting the width of the pressure roller 3, according to the thickness of the pressed paper or the characteristics of different pulping fibers, the locking bolt 15 is loosened, and then the second support 13 is moved up and down. The up and down movement of the second support 13 drives the pressure roller 3 to move up and down. At the same time, the up and down movement of the second support 13 drives the two connecting frames 12 to move up and down until the designated scale line 14 on one side of the connecting frame 12 coincides with the top of the first support 11. Then the two locking bolts 15 are tightened. In this way, while the pressure roller 3 is adaptively adjusted, the position of the pressure roller 3 can also be accurately adjusted so as to adjust the contact pressure between the pressure roller 3 and the paper.

[0077] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
