Description

Its structure is precise and complex, typically composed of a series of components with different functions but working in concert.
[0003] Currently, scraper pressure adjustment is typically done via a unified control system. This system requires operating only one control component to adjust the pressure of all scrapers simultaneously. In simple scraping operations, where fine-tuning of the pressure in each section of the scraper is unnecessary, unified control allows for quick and uniform pressure changes, saving operation time and effort.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 An embodiment of this utility model is provided: a multi-segment scraper pressure regulating device, including a housing 1, a connecting plate 12 fixedly connected to the inner side of the housing 1, a plurality of housings 11 fixedly connected to the inner side of the connecting plate 12, a pressure regulating component provided inside the plurality of housings 11, a plurality of scraper limiting components provided inside the housing 1, scraper cleaning components provided on both sides of the housing 1, and snap-fit components provided on the outer sides of both ends of the housing 1.
[0036] The pressure regulating assembly includes a fixed rod 4 21, which is fixedly connected to the inner side of the end of the housing 11. A spring 1 20 is installed on the bottom side of the fixed rod 4 21. A fixed rod 3 19 is slidably connected to the inner side of the housing 11. The other end of the spring 1 20 is located on the side of the fixed rod 3 19. A spring 2 22 is installed on the other side of the fixed rod 3 19. A connecting rod 2 23 is fixedly connected to the inner side of the fixed rod 3 19. The spring 2 22 is sleeved on the inner side of the connecting rod 2 23. A fixed rod 5 24 is slidably connected to the inner side of the housing 11. The other end of the spring 2 22 is located on the side of the fixed rod 5 24. The connecting rod 2 23 is slidably connected to the inner side of the fixed rod 5 24. When gas enters the housing 11, the gas pressure acts on the fixed rod 3 19, causing it to compress the spring 1 20 and push the spring 2 22 through the connecting rod 2 23, thereby driving the fixed rod 5 24 to move. Springs 20 and 22 act as buffers and fine-tunes the pressure. By changing the compression or extension of the springs through gas pressure, the force applied to the fixed rod 24 is adjusted, ultimately regulating the pressure of the scraper 9 connected to the fixed rod 24. The pressure regulating assembly also includes connecting pipe 15 and connecting pipe 17, both fixedly connected to the inside of the housing 11. A solenoid valve 16 is located at the other end of connecting pipe 15, allowing for rapid opening and closing of the gas path to determine whether gas can enter the housing 11. A proportional valve 18 is located at the other end of connecting pipe 17, precisely regulating the pressure and flow rate of the gas entering the housing 11 based on an externally input electrical signal.
[0037] Reference Figure 1 , Figure 2 and Figure 6 The scraper cleaning assembly includes two connecting blocks 6, which are fixedly connected to the outer ends of the housing 1. Connecting rods 7 are rotatably connected to the inner sides of the two connecting blocks 6, and multiple fixing rods 8 are fixedly connected to the outer sides of the connecting rods 7. Cleaning brushes 26 are installed on the inner sides of each fixing rod 8. Control wheels 10 are rotatably connected to the inner sides of the two connecting blocks 6, and both control wheels 10 are fixedly connected to the outer ends of the two connecting rods 7. Rotating the control wheels 10, which are fixed to the ends of the connecting rods 7, causes the connecting rods 7 to rotate, thereby causing the cleaning brushes 26 on the fixing rods 8 to perform a circular motion around the scraper 9, cleaning the surface of the scraper 9, promptly removing debris and residue adhering to the scraper 9 during operation, ensuring the cleanliness and sharpness of the scraper 9, improving the scraping effect, and extending the service life of the scraper 9.
[0038] Reference Figure 2 and Figure 3The scraper limiting assembly includes a fixing block 13, which is fixedly connected to the outside of the fixing rod 24. Two sliding grooves 27 are formed at both ends of the fixing block 13. Multiple fixing rods 14 are fixedly connected to the bottom side of the connecting plate 12, and these fixing rods 14 are slidably connected to the inside of the sliding grooves 27. Scrapers 9 are fixedly connected to the sides of the fixing block 13. When the fixing rod 24 moves due to pressure adjustment, the fixing block 13 is restricted by the fixing rods 14 within the sliding grooves 27, and can only move in a specific direction. This ensures the stability of the scraper 9's movement direction during pressure adjustment, preventing the scraper 9 from deviating and ensuring the accuracy and stability of the scraping operation.
[0039] Reference Figure 1 , Figure 2 and Figure 5 The snap-fit assembly includes a snap-fit block 2, which is fixedly connected to the outside of the housing 1. A snap-fit block 3 is slidably connected to the inside of the snap-fit block 2, and a fixing bolt 4 is fixedly connected to the inside of the snap-fit block 3. The snap-fit block 2 is fixed to the outside of the housing 1, and the snap-fit block 3 can slide inside the snap-fit block 2. After snap-fit block 3 is engaged with the corresponding mounting part on the external equipment, the fixing bolt 4 is tightened to firmly fix the snap-fit block 3 in the snap-fit block 2, thereby stably installing the entire multi-stage scraper pressure regulating device on the external equipment. Multiple housings 11 have sealing rubber rings 25 fixedly connected to their inner bottom sides, and multiple fixing rods 24 are slidably connected to the inner side of the sealing rubber rings 25. The sealing rubber rings 25 on the inner bottom sides of the multiple housings 11, in close cooperation with the fixing rods 24 sliding within them, effectively prevent gas leakage inside the housing and ensure the accuracy and stability of pressure regulation. Multiple pressure indicators 5 are provided on the outside of the housing 1. The pressure display 5 is connected to the pressure measuring element inside each housing 11, and displays the pressure inside each section of housing 11 in real time, so that the operator can keep abreast of the pressure status and make adjustments.
[0040] Working Principle: Connecting pipes 15 and 17 are connected to the housing 11 and are equipped with a solenoid valve 16 and a proportional valve 18, respectively. The solenoid valve 16 can quickly open and close the gas path, controlling whether gas enters the housing 11; the proportional valve 18 can precisely adjust the gas pressure and flow rate entering the housing 11 based on the input electrical signal. When gas enters the housing 11, pressure acts on the fixed rod 19, compressing or stretching springs 20 and 22. By adjusting the gas pressure, the spring deformation changes, causing the fixed rod 24 to shift, ultimately regulating the pressure of the scraper 9.
[0041] The scraper 9 is fixed to the outside of the fixing rod 24 by the fixing block 13, and the sliding grooves 27 at both ends of the fixing block 13 slide in engagement with the fixing rod 24 at the bottom of the connecting plate 12. This design can limit the movement direction of the scraper 9 during the pressure adjustment process, ensure the stable movement of the scraper 9, avoid deviation, and ensure the stability of the scraping effect.
[0042] When it is necessary to clean the surface of the scraper 9 during operation, the operator can rotate the control wheel 10 to drive the connecting rod 7 to rotate, thereby causing the cleaning brush 26 to clean the scraper 9 and prevent debris from adhering to the scraper 9 and affecting the scraping quality.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
