Technical Field

[0001] This utility model relates to the field of cleaning technology for papermaking production equipment, and specifically to a scraper holder cleaning device. Background Technology

[0002] In the papermaking process, the doctor blade holder is an important component used to install the doctor blade. After the doctor blade cuts the paper, some paper fibers often adhere to its surface. These paper fibers can easily affect the cutting operation of the doctor blade, and thus the cleanliness of its surface directly affects the use effect of the doctor blade and the production quality of the paper.

[0003] Traditional methods of cleaning doctor blade holders rely heavily on manual operation. Operators need to use handheld paper lint suction devices to remove paper lint from the doctor blade surface, or rinse the doctor blade holder with water after cutting the paper. This is not only labor-intensive and inefficient, but also difficult to guarantee cleaning results, easily leading to cleaning dead spots. Residual pulp, ink, and other impurities can affect the installation accuracy and scraping performance of subsequent doctor blades, resulting in scratches, stains, and other quality problems on the paper surface, increasing the scrap rate in the production process and hindering cost reduction and efficiency improvement for enterprises. In addition, manual cleaning also poses certain safety hazards, as operators may suffer mechanical injuries due to improper operation. Utility Model Content

[0061] Please see Figures 1 to 5 This embodiment relates to a scraper holder cleaning device, including a support mechanism 100, a mounting mechanism 200, a lifting mechanism 300, and a cleaning mechanism 400. The support mechanism 100 is a load-bearing base component, used to fix the entire device and provide an installation reference for other mechanisms. The mounting mechanism 200 is rotatably mounted above the support mechanism 100. The rotatability of the mounting mechanism 200 allows the cleaning mechanism 400 to adapt to scraper holders of different models and installation angles, expanding the device's applicability.

[0062] Furthermore, the cleaning mechanism 400 is mounted on the mounting mechanism 200. The mounting mechanism 200 is used to install the cleaning mechanism 400 and adjust its working angle; it is the core structure for achieving cleaning orientation adaptation. The cleaning mechanism 400 is used to clean the scraper holder; it is an actuator for removing impurities, employing a pneumatic cleaning principle to blow away impurities using high-pressure airflow.

[0063] Furthermore, the lifting mechanism 300 is disposed on the support mechanism 100, and the lifting mechanism 300 is connected to the installation mechanism 200. The lifting mechanism 300 is used to lift the installation mechanism 200. The lifting mechanism 300 is a power component that drives the installation mechanism 200 and the cleaning mechanism 400 to move up and down, and is the core of adjusting the cleaning distance.

[0064] Specifically, in this embodiment, the scraper cleaning device has a support mechanism 100 that provides stable support for the entire device, an installation mechanism 200 for fixing and adjusting the cleaning mechanism 400, and a lifting mechanism 300 for vertical displacement of the cleaning mechanism 400. The cleaning mechanism 400 directly completes the impurity removal operation. The rotatable and height-adjustable connection of each mechanism ensures the flexibility and coverage of the cleaning operation. Through the coordinated operation of the support mechanism 100, installation mechanism 200, lifting mechanism 300, and cleaning mechanism 400, traditional manual operation is replaced, achieving automated and precise cleaning of the scraper, significantly reducing labor intensity. The rotatable installation mechanism 200 allows the cleaning mechanism 400 to adapt to scraper frames of different models and installation angles, expanding the device's applicability, avoiding blind spots in manual cleaning, and improving the comprehensiveness of cleaning. Furthermore, the clear division of labor and reliable connection of each mechanism effectively solves the technical problems of low efficiency, poor results, and insufficient safety in manual cleaning.

[0065] Optionally, in some embodiments, such as Figures 1 to 5 As shown, the support mechanism 100 includes a horizontal plate 1 and two support seats 9. Both support seats 9 are fixedly connected to the bottom of both sides of the horizontal plate 1. Each support seat 9 has several mounting holes. These mounting holes allow the device to be fixed to the corresponding position on the production line using bolts or other fasteners, ensuring structural stability during cleaning operations. The symmetrical design of the double support seats 9 enhances the overall load-bearing capacity and operational stability of the device. The mounting holes allow the device to adapt to the installation requirements of different production lines, making it highly versatile.

[0066] Optionally, in some embodiments, such as Figures 1 to 5 As shown, the mounting mechanism 200 includes a first mounting frame 3 and a second mounting frame 4; the first mounting frame 3 is located above the support mechanism 100 and is connected to the lifting mechanism 300; the second mounting frame 4 is located above the first mounting frame 3, and the inner walls of both ends of the first mounting frame 3 are rotatably connected to the second mounting frame 4 via pins; both ends of the first mounting frame 3 are threaded with fastening bolts 8, one end of the fastening bolt 8 extending to the inner side of the first mounting frame 3 and abutting against the end of the second mounting frame 4. Specifically, in this embodiment, as... Figures 1 to 5 As shown, threaded holes are provided at both ends of the first mounting bracket 3, and the fastening bolt 8 is threadedly connected to the first mounting bracket 3 through the threaded holes.

[0067] The first mounting bracket 3 is connected to the lifting mechanism 300, and the second mounting bracket 4 is rotatably connected to the first mounting bracket 3 via a pin, allowing for angle adjustment within the range of 0-90°. After the angle adjustment is completed, the fastening bolts 8 at both ends of the first mounting bracket 3 are fixed in position by abutting against the ends of the second mounting bracket 4. The adjustable angle design allows the cleaning mechanism 400 to adapt to different models and different installation angles of scraper holders, expanding the applicability of the device. The threaded connection of the fastening bolts 8 ensures reliable angle fixation, avoids displacement during the cleaning process, and improves cleaning accuracy.

[0068] Optionally, in some embodiments, such as Figures 1 to 5 As shown, the first mounting bracket 3 is U-shaped, and the second mounting bracket 4 is U-shaped. The U-shaped structure combines structural strength and space utilization, ensuring stable support for the cleaning mechanism 400 while avoiding obstruction of the cleaning path and improving the cleaning effect; the symmetrical U-shaped design makes the force more even and extends the service life of the mechanism.

[0069] Optionally, in some embodiments, such as Figures 1 to 5 As shown, the cleaning mechanism 400 includes an air supply component 13, multiple air pipes 5, and multiple air nozzles 11. The multiple air pipes 5 are respectively mounted on the second mounting bracket 4, and the multiple air nozzles 11 are respectively mounted on the top of the multiple air pipes 5. The air supply component 13 is connected to the multiple air pipes 5 via pipelines, and the air supply component 13 is used to provide air to the air pipes 5. The air supply component 13 delivers high-pressure air to the air pipes 5 through pipelines. The airflow is sprayed out through the air nozzles 11 and acts on the surface of the scraper frame, blowing away impurities such as paper fibers and pulp. In this embodiment, the air supply component 13 is an air compressor or an air tank. The pneumatic cleaning method leaves no liquid residue, avoiding equipment corrosion problems caused by water washing. The distribution design of multiple air pipes 5 and multiple air nozzles 11 expands the cleaning coverage area, and the high-pressure airflow can penetrate gaps to remove dead corners that are difficult to reach by manual cleaning, improving the thoroughness of cleaning.

[0070] Optionally, in some embodiments, such as Figures 1 to 5 As shown, the cleaning mechanism 400 also includes a main pipe 7 and multiple branch pipes 6; the multiple branch pipes 6 are respectively connected to the bottom of the multiple air pipes 5, and the multiple branch pipes 6 are respectively connected to the main pipe 7. One end of the main pipe 7 is fixedly installed with an external port 12, and the external port 12 is connected to the air supply component 13 to form a complete air path of "air supply component 13 → main pipe 7 → branch pipe 6 → air pipe 5 → air nozzle 11". The diversion design of the main pipe 7 and the branch pipes 6 ensures that the airflow pressure of each air nozzle 11 is uniform, avoiding incomplete cleaning caused by insufficient airflow from a single air nozzle 11; the external port 12 facilitates the quick connection and disassembly of the air supply component 13, reducing the difficulty of equipment maintenance.

[0071] Specifically, in this embodiment, as shown in the figure, the lifting mechanism 300 can drive the air pipes 5 on the first mounting frame 3 and the second mounting frame 4 to rise and fall as a whole, achieving cleaning adaptation for scraper frames of different heights. The second mounting frame 4 is rotatably connected to the first mounting frame 3 through a pin, and with the abutment and fixation of the fastening bolts 8, the tilt angle of the air pipes 5 can be flexibly adjusted, thereby accurately aligning with different cleaning areas of the scraper frame and avoiding cleaning dead corners. Multiple air pipes 5 are connected to the main pipe 7 through branch pipes 6. After the air source provided by the air supply component 13, the surface of the scraper frame can be cleaned by air jets in all directions at the same time, quickly and efficiently removing impurities such as paper fibers and pulp, significantly improving the cleaning effect and efficiency, reducing the intensity of manual labor, reducing safety accidents caused by improper manual operation, ensuring the cleanliness of the scraper surface, ensuring the quality of subsequent paper production, reducing the scrap rate, and providing strong support for enterprises to reduce costs and increase efficiency.

[0072] Optionally, in some embodiments, such as Figures 1 to 5 As shown, the lifting mechanism 300 includes a lifting cylinder 2, the output end of which extends to the top of the support mechanism 100 and is fixedly connected to the mounting mechanism 200. Specifically, in this embodiment, as... Figures 1 to 5 As shown, the top of the horizontal plate 1 has an opening, and the output end of the lifting cylinder 2 extends through the opening to the top of the horizontal plate and is fixedly connected to the bottom of the first mounting bracket 3. The lifting mechanism 300 uses the lifting cylinder 2 as its power source. The cylinder body of the lifting cylinder 2 is fixed to the support mechanism 100, and its output end passes through the top of the horizontal plate 1 of the support mechanism 100 and is fixedly connected to the first mounting bracket 3 of the mounting mechanism 200. The extension and retraction of the cylinder piston rod drives the mounting mechanism 200 and the cleaning mechanism 400 to rise and fall, adjusting the distance between the air nozzle 11 and the scraper frame. The cylinder drive achieves automated control of the lifting action, with fast response speed and high positioning accuracy. It can quickly adjust the cleaning distance according to the height of the scraper frame, improving cleaning efficiency. Compared with manual lifting, it reduces human intervention and further ensures operational safety.

[0073] Optionally, in some embodiments, such as Figures 1 to 5 As shown, the lifting mechanism 300 further includes at least one guide lifting rod 10, one end of which passes through the support mechanism 100 and is fixedly connected to the mounting mechanism 200. The guide lifting rod 10 is a guiding component that assists the lifting cylinder 2 in achieving smooth lifting and lowering, preventing deviation during the lifting and lowering of the mounting mechanism 200. At least one guide lifting rod 10 rises and falls synchronously with the mounting mechanism 200, serving as a guide and limiting element to prevent tilting or swaying of the mounting mechanism 200 during lifting and lowering.

[0074] Specifically, in this embodiment, such as Figures 1 to 5As shown, there are two guide lifting rods 10, which are distributed on both sides of the bottom of the mounting mechanism 200. The two guide lifting rods 10, symmetrically distributed on both sides of the bottom of the mounting mechanism 200, form a three-point support structure with the central lifting cylinder 2, jointly constraining the lifting trajectory of the mounting mechanism 200. The symmetrical distribution on both sides makes the guiding force more balanced, further improving the stability of the mounting mechanism 200 and avoiding structural deformation caused by unilateral force. The three-point support structure enhances the overall rigidity, ensuring lifting accuracy after long-term use.

[0075] Optionally, in some embodiments, such as Figures 1 to 5 As shown, the guide lifting rod 10 includes an inner rod 101 and an outer rod 102. One end of the inner rod 101 is nested within the inner wall of the outer rod 102, and the inner rod 101 and the outer rod 102 are slidably connected. The other end of the inner rod 101 is fixedly connected to the bottom of the mounting mechanism 200, and the outer rod 102 is fixed to the horizontal plate 1 of the support mechanism 100. During lifting, the inner rod 101 slides back and forth along the inner wall of the outer rod 102. The nested sliding structure provides high guiding accuracy and low frictional resistance, ensuring smooth lifting. The cooperation between the inner rod 101 and the outer rod 102 effectively prevents dust and impurities from entering, extending the service life of the guide lifting rod 10 and reducing maintenance costs.

[0076] The scraper holder cleaning device in this embodiment achieves the cleaning operation through the following steps, with each mechanism working in concert to ensure the cleaning effect:

[0077] Device fixing: The entire device is fixed to the corresponding position on the paper production line through the mounting holes on the support base 9 of the support mechanism 100, so that the cleaning mechanism 400 is aligned with the area to be cleaned by the scraper holder.

[0078] Angle adjustment: Loosen the fastening bolts 8 at both ends of the first mounting bracket 3, rotate the second mounting bracket 4 through the pin shaft, and adjust the orientation of the air nozzle 11 of the cleaning mechanism 400 so that it forms the best cleaning angle with the surface of the scraper frame; after the angle is determined, tighten the fastening bolts 8 to fix the second mounting bracket 4.

[0079] Height positioning: Start the lifting cylinder 2 of the lifting mechanism 300. The cylinder output end pushes the installation mechanism 200 to rise or fall. At the same time, the inner rod 101 of the guide lifting rod 10 slides synchronously along the outer rod 102 until the air nozzle 11 and the surface of the scraper frame reach the preset cleaning distance.

[0080] Pneumatic cleaning: When the air supply component 13 is activated, high-pressure gas is distributed from the main pipe 7 to each branch pipe 6, and then delivered to multiple air nozzles 11 through the air pipe 5. The air nozzles 11 spray high-pressure airflow onto the surface of the scraper frame to blow away the attached paper fibers, pulp, ink and other impurities.

[0081] Operation completed: After cleaning is completed, the air supply component 13 stops supplying air, and the lifting cylinder 2 drives the installation mechanism 200 to reset, waiting for the next cleaning instruction.

[0082] Specifically, in use, firstly, using bolts, the entire device is fixed to a suitable position on the paper machine through the mounting holes on the support seats 9 at both ends of the horizontal plate 1, ensuring that the air jet direction of the air pipe 5 can cover the cleaning area of ​​the doctor blade holder. Next, connect the external port 12 at one end of the main pipe 7 to the air supply component 13 to provide a stable airflow for the cleaning operation. Before starting the cleaning program, according to the actual tilt angle and installation position of the doctor blade holder, loosen the fastening bolts 8 at both ends of the first mounting bracket 3, rotate the second mounting bracket 4 through the pin, and adjust the tilt angle of the air pipe 5 and the air nozzle 11 so that the air nozzle 11 can be accurately aligned with the paper lint adhesion area on the doctor blade surface. After adjustment, tighten the fastening bolts 8 again to fix the position of the second mounting bracket 4.

[0083] When cleaning of the scraper holder is required, the lifting mechanism 300 is activated. The output end of the lifting mechanism 300 drives the first mounting bracket 3 to rise or fall along the direction of the guide lifting rod 10 until the air nozzle 11 at the bottom of the air pipe 5 maintains a suitable cleaning distance from the surface of the scraper holder. Then, the external air source is turned on, and high-pressure gas enters each branch pipe 6 through the main pipe 7, and is then distributed to each air pipe 5 through the branch pipes 6. Finally, it is ejected from the air nozzle 11 as a high-speed airflow, powerfully blowing away impurities such as paper fibers, pulp, and ink from the surface of the scraper holder.

[0084] During the cleaning process, the lifting mechanism 300 can be controlled to move the air nozzle 11 up and down on the surface of the scraper frame, ensuring thorough cleaning of the entire working surface and avoiding any blind spots. After cleaning, the air supply is turned off, and the lifting mechanism 300 resets the first mounting bracket 3 and air pipe 5, awaiting the next cleaning instruction. This automated operation process enables efficient and precise cleaning of the scraper frame, effectively replacing traditional manual cleaning methods and significantly improving cleaning efficiency and quality.

[0085] The advantages of the above technical solution, which differ from existing technologies, are as follows:

[0086] High degree of automation: The lifting and cleaning are driven by cylinders and pneumatic cleaning replaces manual operation, which greatly reduces labor intensity, improves cleaning efficiency, and can meet the needs of continuous operation of production lines.

[0087] Thorough cleaning effect: The 11 evenly distributed air nozzles and adjustable angle design ensure that the airflow covers the entire surface of the scraper holder, leaving no dead corners and effectively avoiding paper quality defects.

[0088] High safety: No manual close contact with the scraper holder and mechanical parts is required throughout the process, completely eliminating the risk of mechanical injury and improving the safety of production operations.

[0089] Wide adaptability: The adjustable angle and height structure design can be adapted to different models and installation positions of scraper holders, making it highly versatile.

[0090] Low maintenance cost: The structure of each mechanism is simple and the connection is reliable. Pneumatic cleaning leaves no liquid residue, avoids equipment corrosion, extends the service life of the device, and reduces maintenance frequency and cost.

[0091] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application, and that utilize the content described in the text and drawings of this application to make equivalent structural or procedural substitutions or modifications, as well as any direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
