[0022] The space between the vacuum transfer roll and the spray pipe on the paper machine is limited. To install a water-blocking device, the design must be tailored to the available space. Furthermore, the adjustable-height, cross-width scraper device needs to be rigidly designed to prevent scraper vibration from affecting the paper machine's operation during high-speed running. The design scheme in this embodiment prevents paper web tears and breaks caused by water spraying, thus improving equipment operating efficiency.

[0023] This application provides a height-adjustable baffle device for papermaking equipment. Specifically, the baffle device can be installed in the gap space between a vacuum transfer roll and the outlet spray pipe of the vacuum transfer roll.

[0024] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of an embodiment of the height-adjustable baffle device for papermaking equipment according to this application. Figure 2 yes Figure 1 A side view of the water-blocking device in this embodiment; the water-blocking device in this embodiment includes, but is not limited to, a water-blocking unit 100 and an adjusting unit 200. Figure 1 The water-blocking device consists of two oppositely arranged devices with similar structures. The length of the water-blocking device can be designed according to actual needs, and no specific limitation is made here.

[0025] Specifically, the water-blocking unit 100 includes a water-blocking plate 110 and a connecting frame 120, with the water-blocking plate 110 and the connecting frame 120 fixedly connected. The adjusting unit 200 includes a fixing rod 210 and an adjusting rod 220, with the connecting frame 120 connected to the adjusting rod 220. One end of the fixing rod 210 is fixedly connected to the frame of the papermaking equipment (not shown in the figure) (specifically, it can be welded), and the other end is connected to the adjusting rod 220. The fixing rod 210 adjusts the height of the water-blocking unit 100 by changing its connection position with the adjusting rod 220.

[0026] Optionally, the connecting frame 120 in this embodiment includes a first adjusting sleeve 121 and a support rod 122. The first adjusting sleeve 121 is fixedly connected to the support rod 122, and the baffle plate 110 is fixedly connected to the support rod 122. The first adjusting sleeve 121 is sleeved on the adjusting rod 220. By changing the connection position with the adjusting rod 220, the height of the baffle plate 110 can be adjusted.

[0027] In this embodiment, the connecting frame 120, the fixing rod 210, and the adjusting rod 220 can all be made of stainless steel. Optionally, the adjusting rod in this embodiment can be a screw structure with threads on its outer circumference. The first adjusting sleeve 121 is sleeved on the adjusting rod 220, and the connection position between the first adjusting sleeve 121 and the adjusting rod 220 is adjusted by the first adjusting nuts 123 at both ends.

[0028] Optionally, the support rod 122 in this embodiment further includes a support horizontal rod 1221 and a support vertical rod 1222. The support horizontal rod 1221 is fixedly connected to the first adjusting sleeve 121, the support vertical rod 1222 is fixedly connected to the support horizontal rod 1221, and the baffle plate 110 is fixedly connected to the support vertical rod 1222.

[0029] Alternatively, please continue reading Figure 1 In this embodiment, the water-blocking unit 100 also includes a connecting strip 130, which is fixedly connected to the water-blocking plate 110. The water-blocking plate 110 is connected to the supporting vertical rod 1222 through the connecting strip 130.

[0030] Optionally, please refer to Figure 3 , Figure 3 This is a structural schematic diagram of an embodiment of the baffle plate of this application. In this embodiment, the baffle plate 110 includes a straight section 111 and an arc section 112 of integral structure. The connecting strip 130 is fixedly connected to the straight section 111. The included angle α between the arc section 112 and the straight section 111 is 120° to 140°, specifically 120°, 125°, 137°, 140°, etc. In one embodiment, it can be 137°. The 137-degree angle of the scraper with an arc design is the final angle determined after repeated verification and multiple studies. It meets the requirement of being consistent with the rotation direction of the paper machine pressure blanket. The arc design ensures smooth water flow during the reverse swing. It is designed in accordance with the principle of water flow. In order to prevent water rebounding from the transfer roller and returning to the paper web, the scraper device needs to be designed to allow water droplets to flow downwards.

[0031] The working principle of the baffle device in this embodiment is as follows: Water sprayed from the fixed spray pipe in front of the vacuum transfer roll cleans the roll surface. During the high-speed operation of the vacuum transfer roll, water mist is generated and splashes onto the upper blanket. The paper web passing through the blanket is torn under the action of the high-pressure water mist, causing paper breaks. After the baffle device in this embodiment is installed, adjusting the baffle device to collect the gradually forming water vapor and mist prevents it from dripping onto the paper web, effectively avoiding paper web tears and greatly improving the paper machine's operating efficiency.

[0032] Please see Figure 4 , Figure 4 This is a schematic diagram of another embodiment of the water-blocking device of this application. The water-blocking device in this embodiment can also include a water-blocking unit 100 and an adjusting unit 200.

One end of the fixing rod 210 is used to be fixedly connected to the frame of the papermaking equipment (not shown in the figure) (specifically, it can be fixed by welding), and the other end is connected to the adjusting rod 220. The height of the water-blocking unit 100 can be adjusted by changing the connection position of the fixing rod 210 with the adjusting rod 220.
