Description

Technical Field

[0001] The utility model belongs to the field of paper sheet production, relates to the technology of a vacuum suction roller for paper sheets, and specifically provides a vacuum box structure of the vacuum suction roller. Background Art

[0002] like Figure 1 As shown, the vacuum area 10 of the vacuum box of the old suction roller is divided into a low vacuum area 101' and a high vacuum area 102', which are arranged side by side, and vacuum suction and pressing are performed on both sides of the operating side and the transmission side. Since the area of ​​the high vacuum area 102' is relatively small, the vacuum suction force provided to both sides of the low vacuum area 101' is insufficient, and the paper sheets are prone to falling off on both sides of the vacuum suction roller, thereby causing paper breaks and affecting the production efficiency of the paper machine. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art; to this end, the present invention proposes a vacuum box structure of a vacuum suction roller, which is used to solve the technical problem of edge falling.

[0004] To achieve the above objectives, the first aspect of the present invention provides a vacuum box structure for a vacuum suction roller, comprising:

[0005] A vacuum box structure of a vacuum suction roller comprises a roller body, wherein at least a pair of first partitions are provided on the roller body in a radial direction;

[0006] A vacuum zone is formed between the pair of first partitions; the length direction of the pair of first partitions is parallel to the axis of the roller body, and a second partition is provided on the roller body in parallel with the pair of first partitions;

[0007] The second partition divides the vacuum area into a low vacuum area and a high vacuum area, and the second partition is close to the first partition on the high vacuum area side;

[0008] Fixed partitions are provided at both ends of the second partition close to the low vacuum area;

[0009] The fixed partition, the second partition and the first partition close to the low vacuum area form a closed loop low vacuum area;

[0010] A third partition is provided on the outer side of each end of the roller body corresponding to the second partition. The third partition and the first partition form a closed-loop vacuum area on the roller body. A vacuum notch is provided in the vacuum area.

[0011] The third partition plate, the fixed partition plate, the first partition plate close to the high vacuum zone and the second partition plate form a closed loop connected to the high vacuum zone.

[0012] During operation, the high vacuum area is improved to form a concave shape and wrapped on both sides of the low vacuum area, so that the two sides of the original low vacuum area become high vacuum areas, which increases the vacuum suction force of the paper sheets on both sides of the low vacuum area of ​​the vacuum suction roller, making it less likely for the paper sheets to fall off on both sides of the vacuum suction roller. This effectively solves the problem that the traditional vacuum suction roller has insufficient vacuum suction force on both sides of the low vacuum area, which is prone to falling off and even paper breaking in the subsequent pressing work.

[0013] As a further technical solution of the present invention: the distance between the third partition and the fixed partition can be adjusted; it is convenient to adjust the width of the vacuum zone and the area of ​​the high vacuum zone on both sides, so as to better adapt to different operating requirements.

[0014] As a further technical solution of the present invention: at least one width adjustment rod is provided in the high vacuum area, one end of the width adjustment rod is connected to the third partition, and the side away from the third partition is movably connected in the vacuum area.

[0015] As a further technical solution of the utility model: there are two width adjustment rods, which are arranged parallel to the second partition;

[0016] One of the width adjustment rods is located on the side of the second partition close to the high vacuum area and is movably connected in the high vacuum area through an adjustment seat;

[0017] The other width adjustment rod is located on a side of the second partition close to the fixed partition, passes through the fixed partition and extends into the low vacuum area, and is movably connected through the adjustment seat.

[0018] As a further technical solution of the present invention: the adjustment seat includes a base and a sleeve, the sleeve is connected to the top of the base, the width adjustment rod is sleeved on the sleeve and can be locked; the adjustment seat is installed on the roller body through the base.

[0019] As a further technical solution of the present invention: the width adjustment rod is connected to the third partition through a fixing seat.

[0020] As a further technical solution of the present invention: the fixed partition is provided with a through hole, the width adjustment rod is sleeved on the through hole, and a sealing ring is provided on the through hole.

[0021] As a further technical solution of the present invention: the first partition, the second partition, the fixed partition and the top of the third partition are all provided with sealing strips, which are installed on the sealing grooves set at the corresponding positions to improve the sealing effect of the vacuum area.

[0022] As a further technical solution of the present invention: the vacuum notches are arranged at intervals along the length direction of the second partition, so that the vacuum suction force is more uniform.

[0023] As a further technical solution of the present invention: the vacuum groove extends radially along the roller body to the low vacuum zone and high vacuum zone on both sides of the second partition, so that the vacuum suction of the low vacuum zone and the high vacuum zone to the paper sheet can be smoothly connected.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention improves the high vacuum area to form a concave shape, which is wrapped around the two ends of the low vacuum area, so that the two sides of the original low vacuum area become high vacuum areas, and the vacuum suction force of the paper sheets on both sides of the low vacuum area of ​​the vacuum suction roller is increased, so that the paper sheets are not prone to edge falling on both sides of the vacuum suction roller, which effectively solves the problem that the traditional vacuum suction roller has insufficient vacuum suction force on both sides of the low vacuum area, which is prone to edge falling and even paper breaking in the subsequent pressing work.

[0037] The second partition 12 divides the vacuum area 10 into a low vacuum area 101 and a high vacuum area 102, and the second partition is close to the first partition on the side of the high vacuum area; thus, the low vacuum area 101 has a large area and the high vacuum area 102 has a small area;

[0038] Fixed partitions 13 are provided at both ends of the second partition 12 close to the low vacuum zone 101;

[0039] The fixed partition 13, the second partition 12 and the first partition 11 close to the low vacuum zone 101 form a closed loop low vacuum zone 101;

[0040] The roller body 1 is provided with third partitions 14 on the outer sides of both ends of the second partition 12. The third partitions 14 and the first partitions 11 form a closed-loop vacuum area 10 on the roller body 1. A vacuum notch 103 is provided in the vacuum area 10.

[0041] The third partition plate 14 , the fixed partition plate 13 , the first partition plate 11 close to the high vacuum zone 102 , and the second partition plate 12 form a closed loop communicating with the high vacuum zone 102 .

[0042] The distance between the third partition and the fixed partition can be adjusted. In an exemplary embodiment, at least one width adjustment rod 15 is provided in the high vacuum area 102. One end of the width adjustment rod 15 is connected to the third partition 14, and the side away from the third partition 14 is movably connected in the vacuum area 10. Exemplarily, the width adjustment rod 15 is connected to the third partition 14 through a fixed seat (not shown in the figure).

[0043] There are two width adjustment rods 15, which are arranged parallel to the second partition 12; one of the width adjustment rods 15 is located on the side of the second partition 12 close to the high vacuum zone 102, and is movably connected to the high vacuum zone 102 through an adjustment seat 16; the adjustment seat 16 includes a base 161 and a sleeve 162, the sleeve 162 is connected to the top of the base 161, and the width adjustment rod 15 is sleeved on the sleeve 162 and can be locked; illustratively, it can be locked by a locking screw. The adjustment seat 16 is mounted on the roller body through the base 161. illustratively, the base 161 is mounted on the roller body by screws;

[0044] Another width adjustment rod 15 is located on a side of the second partition plate 12 close to the fixed partition plate 13 , passes through the fixed partition plate 13 and extends into the low vacuum area 101 , and is movably connected via an adjustment seat 16 .
