[0017] The embodiments will be further described below with reference to the accompanying drawings.

[0018] like Figures 1-4 As shown in the preferred embodiment 1, a water-blocking fixture is used on the side of the scraper of the rotating drum. The fixture is installed on the scraper plate 2 on one side of the rotating drum 1, and on both ends of the scraper plate 2 away from the rotating drum 1. Each fixture includes a mounting component 3. One end of the mounting component 3 is detachably fixed to the scraper plate 2 by several fasteners, and the other end of the mounting component 3 is detachably fixed to a flexible scraper 6 by several fixing components 4. The orientation of the flexible scraper 6 is the same as that of the scraper 9 on the scraper plate 2, ensuring that the rotating drum 1 can cooperate with the flexible scraper 6 in the same way as the scraper 9. It is equivalent to adding scrapers on both sides of the scraper plate 2 to further control the thickness of the material on the rotating drum 1. The mounting component 3 is provided with several adjusting components 5 to adjust the tilt angle of the flexible scraper 6. The thickness on both sides can be adjusted according to the actual situation. If a thinner thickness is required, the tilt angle is increased; if a thicker thickness is required, the tilt angle is decreased, which increases the applicability and facilitates adjustment.

[0019] The tooling is symmetrically arranged about the middle position of the scraper plate 2. This ensures stability during use and prevents material accumulation at both ends of the drum 1.

[0020] The flexible scraper 6 is made of silicone. The flexible scraper 6 is designed to have a certain degree of deformability, and its angle can be adjusted via the adjusting component 5. Food-grade silicone is used.

[0021] The device is easy to install. It uses the original scraper plate 2 as a base and installs this fixture at both ends to prevent material from accumulating on both sides and causing water leakage. When in use, the mounting component 3 is installed on the scraper plate 2 with fasteners. Then, the flexible scraper plate 6 is fixedly installed by the fixing component 4. The adjustment component 5 is adjusted according to the required thickness on both sides of the material. The flexible scraper plate 6 is pressed tightly against the adjustment component 5 under the pressure provided by the material rotating on the drum 1 to form a limit. The tilt angle limited by the adjustment component 5 is used to further scrape the two sides to prevent material from accumulating on both sides and causing water leakage.

[0022] As a more preferred embodiment 2, the mounting assembly 3 includes a fixing plate 301, which is detachably fixed to the scraper plate 2 by at least two third screws 7. A mounting plate 303 is provided on the side of the fixing plate 301 away from the scraper plate 2. The mounting plate 303 is fixedly connected to the fixing plate 301 by an extension plate 302. The flexible scraper 6 is detachably fixed to the side of the mounting plate 303 near the scraper plate 2 by a number of fixing components 4.

[0023] Preferably, the cap of the third screw 7 is provided with a second washer 8 on the fixing plate 301.

[0024] The fixed plate 301 is parallel to the scraper plate 2, the mounting plate 303 is parallel to the fixed plate 301, and the extension plate 302 is perpendicular to the fixed plate 301. The extension plate 302 creates a certain adjustment space between the fixed plate 301 and the mounting plate 303, providing room for angle adjustment of the flexible scraper 6. Simultaneously, the positional relationship of the mounting plate 303 being parallel to the fixed plate 301 and the extension plate 302 being perpendicular to the fixed plate 301 facilitates the use of the device and allows it to operate in a manner similar to the existing scraper 9.

[0025] Preferably, the mounting plate 303, the extension plate 302, and the fixing plate 301 are integrally formed to create a zigzag steel plate structure.

[0026] The fixing components 4 are arranged at equal intervals along the direction parallel to the extension of the scraper plate 2, and are used to fix the flexible scraper plate 6 near the middle position. The adjusting components 5 are arranged at equal intervals along the direction parallel to the extension of the scraper plate 2, and are used to adjust the tilt of the flexible scraper plate 6 near the top position.

[0027] Preferably, there are at least two fixing components 4 and at least two adjusting components 5.

[0028] Each of the fixing components 4 includes a first screw 401. The cap of the first screw 401 cooperates with the side of the mounting plate 303 near the scraper plate 2 to press the flexible scraper 6. The screw of the first screw 401 passes through the mounting plate 303 and is threadedly connected to a first nut 402. The first nut 402 cooperates with the cap of the first screw 401 to press the mounting plate 303 and the flexible scraper 6.

[0029] During installation, tighten the first nut 402 so that the first nut 402 and the cap end of the first screw 401 cooperate to press the mounting plate 303 and the flexible scraper 6, thus completing the fixation of the flexible scraper 6.

[0030] Preferably, a first washer 403 is provided between the first nut 402 and the mounting plate 303.

[0031] Each of the adjustment components 5 includes a second nut 502. The second nut 502 is welded and fixed to the side of the mounting plate 303 away from the scraper plate 2. The screw of the second screw 501 is threaded with the second nut 502 and passes through the mounting plate 303 and forms a limiting fit with the flexible scraper plate 6 near the top position. The screw of the second screw 501 is threaded with a third nut 503 on the side near the flexible scraper 6. The third nut 503 cooperates with the mounting plate 303 to form a limiting fit on the second screw 501.

[0032] During adjustment, rotate the second screw 501 to a suitable position so that the screw protrudes from the mounting plate 303 by a suitable length. Then tighten the third nut 503 to lock the position of the second screw 501, ensuring stability during subsequent operation. When the drum 1 is running, the material layer on the drum 1 applies pressure to the flexible scraper 6. The second screw 501 abuts against the flexible scraper 6 to provide a reaction force to fix the flexible scraper 6, thereby enabling the flexible scraper 6 to provide scraping operation according to the set tilt angle.

[0033] Preferably, the mounting component 3, the fixing component 4, and the adjusting component 5 are all made of 304 stainless steel.

[0034] This design effectively reduces the contact area of ​​the drum during production, greatly minimizing the risk of wet material on the drum. After testing, it was concluded that the silicone reinforcing plate is the most ideal solution.

[0035] In a preferred embodiment 3, the scraper plate 2 is located near the lower side of the drum 1, the scraper blades 9 on the scraper plate 2 are arranged upwards, and the top of the flexible scraper plate 6 is higher than the top of the scraper blades 9. This ensures the normal operation of the flexible scraper plate 6 and prevents it from interfering with the scraper blades 9.

[0036] In a preferred embodiment 4, the top of the flexible scraper 6 is arranged at an angle, with the end of the flexible scraper 6 near the middle of the scraper plate 2 being lower than the end of the flexible scraper 6 away from the middle of the scraper plate 2. This further ensures the effectiveness of the flexible scraper 6 by minimizing the thickness near the end and preventing material accumulation due to excessive thickness at the end.

[0037] The working principle of this utility model: The device is easy to install. It uses the original scraper plate 2 as a base and installs this fixture at both ends to prevent material from accumulating on both sides and causing water leakage. When in use, the mounting component 3 is installed on the scraper plate 2 with fasteners. Then, the flexible scraper plate 6 is fixedly installed by the fixing component 4. The adjustment component 5 is adjusted according to the required thickness on both sides of the material. The flexible scraper plate 6 is pressed tightly against the adjustment component 5 under the pressure provided by the material rotating on the drum 1 to form a limit. The tilt angle limited by the adjustment component 5 is used to further scrape the two sides to prevent material from accumulating on both sides and causing water leakage.
