Technical Field

[0001] The invention relates to the technical field of belt cleaning, in particular to a T-shaped centrifugal scraper double-stage cleaner. Background Art

[0002] In the existing belt cleaning technology, common cleaning devices often have problems such as poor cleaning effect, complicated operation or poor adaptability. Especially for the belts in large mechanical equipment, due to their harsh working environment, they often need to face adverse conditions such as high humidity and high dust. Traditional cleaning methods often cannot achieve ideal cleaning effects. In addition, with the improvement of the automation level of mechanical equipment, the requirements for automation and intelligence of cleaning devices are also getting higher and higher. The T-type centrifugal scraper two-stage cleaner can fit tightly to the conveyor belt through its unique scraper design, effectively scrape off these adhered material residues, thereby keeping the conveyor belt clean and running efficiently.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example

[0029] Reference Figure 1-Figure 4 A T-shaped centrifugal scraper double-stage cleaner comprises an operating panel 1 and a frame 2 arranged on the operating panel 1. The operating panel 1 is integrated with a lifting part for driving the frame 2 to rise and fall, which is used to adjust the contact pressure and distance between the scraper head 212 and the conveyor belt, and can be adapted to clean the belts with different spacings. The frame 2 is a supporting structure of the scraper head 212, which is connected to the operating panel 1 through the lifting part and can be adjusted up and down according to actual needs. It also includes: a plurality of scraper heads 212 arranged on the frame 2, wherein every two adjacent scraper heads 212 are staggered front and back, and the scraper head 212 is the core component of the cleaner, which is used to directly scrape In order to remove the residual materials on the conveyor belt, every two adjacent scraper heads 212 are staggered front and back. This design can ensure that no area is missed during the scraping process, while reducing the friction and wear between the scraper head 212 and the belt. The operating panel 1 is provided with a lifting part for driving the skeleton 2 to rise and fall, and four pull plates 412 are rotatably installed at the four ends of the skeleton 2. Among them, the two pull plates 412 on the same side are rotatably installed with adjusting rollers 47, and the adjusting roller 47 is provided with an adjusting part for controlling the rotation of the skeleton 2, which allows adjustment according to the inclination state of the conveyor belt to ensure the optimal contact angle and scraping effect between the scraper head 212 and the belt.

[0030] Before use, first adjust the height of the frame 2 through the lifting part on the operating panel 1 so that the scraper head 212 maintains appropriate contact pressure and distance with the conveyor belt. Then, according to the inclination of the conveyor belt, fine-tune the frame 2 through the adjustment part on the adjustment roller 47 to ensure the best scraping effect of the scraper head 212. When the conveyor belt starts to move, the scraper head 212 will fit tightly against the surface of the belt and use its own hardness and sharpness to scrape off the residual material on the belt. Since every two adjacent scraper heads 212 are staggered front and back, it can be ensured that no area will be missed during the scraping process.

[0031] Reference Figure 1-Figure 3The lifting part includes a sliding base 33 slidably mounted on the operating panel 1. The design of the sliding base 33 ensures its smooth movement on the slide rail 32, thereby realizing the lifting and lowering control of the frame 2. A lifting rod 36 is rotatably mounted on the sliding base 33. The design of the lifting rod 36 allows it to rotate at a certain angle on the sliding base 33 to adapt to the position change of the frame 2 during the lifting process. A movable head 37 is rotatably mounted on the lifting rod 36, and a rotating head 38 is rotatably mounted on the movable head 37. A lifting slot 28 is provided on the frame 2. The rotating head 38 is slidably mounted in the lifting slot 28. The rotating head 38 can It slides in the lifting groove 28, thereby realizing the lifting movement of the skeleton 2. At the same time, the rotation of the movable head 37 and the rotating head 38 enables the skeleton 2 to be rotated and adjusted according to the inclination angle of the belt. The operating panel 1 is fixedly connected with a slide rail 32, and the sliding base 33 is slidably installed in the slide rail 32. The slide rail 32 is fixedly connected with a driving motor 3, and the output shaft of the driving motor 3 is fixedly connected with a screw rod 31. The screw rod 31 is threadedly engaged with the sliding base 33. The screw rod 31 is threadedly engaged with the sliding base 33. When the driving motor 3 is started, the screw rod 31 will drive the sliding base 33 to perform lifting movement on the slide rail 32.

[0032] When the height of the skeleton 2 needs to be adjusted, the drive motor 3 is started first. The output shaft of the drive motor 3 will drive the screw rod 31 to rotate. Since the screw rod 31 is threadedly engaged with the sliding base 33, when the screw rod 31 rotates, the sliding base 33 will move linearly on the slide rail 32. This linear motion is achieved by the rotation of the screw rod 31 and the threaded cooperation of the sliding base 33, and has the characteristics of smooth movement and high precision. As the sliding base 33 moves linearly, the lifting rod 36 will also be forced to move upward, thereby driving the lifting and lowering of the skeleton 2. By adjusting the height of the skeleton 2, the contact pressure and distance between the scraper head 212 and the conveyor belt can be adjusted accordingly. This adjustment is crucial to ensuring the best scraping effect of the scraper head 212 and the service life of the belt.

[0033] Reference Figure 1-Figure 4The adjusting part includes a driving gear 4 rotatably mounted on the operating panel 1, a threaded rod 41 is fixedly connected to the driving gear 4, a matching rod 42 is meshingly mounted on the threaded rod 41, and rotates with the rotation of the driving gear 4, the matching rod 42 is meshingly mounted with the threaded rod 41, when the threaded rod 41 rotates, the matching rod 42 will move axially along the threaded rod 41, a spring sleeve rod 44 is mounted on the matching rod 42, a push rod 45 is slidably mounted in the spring sleeve rod 44, the design of the spring sleeve rod 44 allows the push rod 45 to perform telescopic movement within a certain range, and maintain a certain stability through the elastic force of the spring, an adjusting roller 47 is rotatably mounted on the push rod 45, and the adjusting roller 47 allows it to rotate at a certain angle on the push rod 45 to adapt to the position change of the skeleton 2 during the adjustment process, a first connecting rod 34 is fixedly connected to the sliding base 33, and a walking gear is fixedly connected to the first connecting rod 34 Plate 35, the walking tooth plate 35 is meshed and installed with the driving gear 4, and the movement of the sliding base 33 drives the walking tooth plate 35 to move synchronously, and the driving gear 4 is driven to rotate by the walking tooth plate 35, the matching rod 42 is fixedly connected with the mounting head 43, the spring sleeve rod 44 is fixedly connected to the mounting head 43, the adjusting roller 47 is fixedly connected with the roller shaft 46, the roller shaft 46 is rotatably installed on the top rod 45, and the roller shaft 46 is rotatably installed with a pull plate 412, the pull plate 412 is fixedly connected with the third connecting rod 414, the skeleton 2 is fixedly connected with a mounting plate 413, the third connecting rod 414 is rotatably installed on the mounting plate 413, the pull plate 412 is rotatably installed on the mounting plate 413 through the third connecting rod 414, the mounting plate 413 is fixedly connected to the skeleton 2, the pull plate 412 allows it to be connected with the adjusting roller 47, and drives the skeleton 2 to be fine-tuned by the movement of the adjusting roller 47.

[0034] When the position of the skeleton 2 needs to be adjusted, the driving gear 4 is first driven to rotate by an external driving device. As the driving gear 4 rotates, the mating rod 42 meshed with it will move axially along the threaded rod 41. This movement is achieved through the meshing action of the threads, and has the characteristics of smooth movement and high precision. The movement of the mating rod 42 will drive the spring sleeve rod 44 and the push rod 45 inside it to perform telescopic movement. Since the design of the spring sleeve rod 44 allows the push rod 45 to be telescopic within a certain range, the position of the adjusting roller 47 can be fine-tuned. As the push rod 45 telescopes, the adjusting roller 47 will rotate on the push rod 45 at a certain angle. At the same time, since the pull plate 412 is rotatably installed on the mounting plate 413 through the third connecting rod 414, the rotation of the adjusting roller 47 will drive the pull plate 412 to move, and this movement will be further transmitted to the skeleton 2, thereby achieving fine-tuning of the position of the skeleton 2. Since the traveling tooth plate 35 is meshed and installed with the driving gear 4, when the driving gear 4 rotates, the traveling tooth plate 35 will move along the tooth surface of the driving gear 4. This movement will be synchronized with the movement of the matching rod 42, thereby ensuring the stability and accuracy of the sliding base 33 and the frame 2 during the adjustment process.

[0035] Reference Figure 4-Figure 7A scraper frame 29 is fixedly connected to the skeleton 2, a scraper plate 210 is fixedly connected to the scraper frame 29, a scraper head 212 is fixedly connected to the scraper plate 210, an air hole 211 is opened on the scraper plate 210, a cavity is opened in the scraper frame 29 and is connected to the air hole 211, the design of the cavity allows gas to flow inside the scraper frame 29 and spray out through the air hole 211 to assist the cleaning work of the scraper head 212, wherein an air box 5 is fixedly connected to the skeleton 2, an air bag 53 is fixedly connected to the air box 5, an air outlet of the air bag 53 is fixedly connected to an air pipe 51, the air pipe 51 is fixedly connected to the cavity in the scraper frame 29, and the air bag 53 serves as a component for gas storage and release, a lever 48 is fixedly connected to the roller shaft 46, the lever 48 rotates with the rotation of the roller shaft 46, a rotating plate 49 is rotatably installed on the lever 48, and a rotating plate 49 is fixedly connected to the rotating plate 49 A second connecting rod 410 is rotatably mounted on the second connecting rod 410, and a pull rod 411 is connected to the rotating plate 49 through the second connecting rod 410. The pull rod 411 is slidably mounted on the air box 5 and moves with the rotation of the rotating plate 49. The pull rod 411 is slidably mounted on the air box 5, wherein push plates 52 are fixedly connected on both sides of the airbag 53, and a slider 54 is fixedly connected on the push plate 52. A slide groove 55 is provided on the air box 5, and the slider 54 is slidably mounted in the slide groove 55. A slide groove 55 is provided on the air box 5, and the slider 54 is slidably mounted in the slide groove 55. This design allows the volume of the airbag 53 to be changed by moving the push plate 52 and the slider 54 when inflating or deflating. The pull rod 411 is fixedly connected to the push plate 52, and the movement of the push plate 52 driven by the pull plate 412 can change the volume of the airbag 53, so that the airbag 53 can be inflated or deflated.

[0036] When the cleaner is not working, the airbag 53 is in an uninflated state, the push plate 52 and the slider 54 are located at a certain position of the slide groove 55, and the pull rod 411 is also in its initial position. When the roller 46 starts to rotate, the lever 48 will also rotate accordingly. The rotation of the lever 48 will drive the rotating plate 49 and the second connecting rod 410 to move. Since the pull rod 411 is connected to the rotating plate 49 through the second connecting rod 410, and the pull rod 411 is slidably installed on the air box 5, the rotation of the rotating plate 49 will drive the pull rod 411 to slide on the air box 5, and the sliding of the pull rod 411 will further drive the push plate 52 to move in the slide groove 55. This movement The movement will change the volume of the airbag 53, thereby causing it to be inflated or deflated. When the airbag 53 is inflated, the internal pressure will be transmitted to the cavity in the scraper frame 29 through the air pipe 51, and further ejected through the air hole 211. The ejected gas can assist the scraper head 212 to scrape off the residue on the conveyor belt. When the airbag 53 is deflated, the gas can be extracted from the scraper frame 29 in some way to perform the next inflation operation. As the roller 46 continues to rotate, the airbag 53 will continuously perform the above-mentioned cyclic motion, thereby realizing the continuous supply and release of gas to assist the scraper head 212 in cleaning.

[0037] Reference Figure 7 , adjustment plates 22 are slidably installed at both ends of the skeleton 2, and the adjustment plates 22 are slidably installed at both ends of the skeleton 2, providing adjustment flexibility, an adjustment slot 23 is opened on the adjustment plate 22, and an adjustment frame 21 is slidably installed on the adjustment slot 23, and the adjustment frame 21 is fixedly installed on the skeleton 2. This design allows the adjustment frame 21 to be adjusted relative to the adjustment plate 22, thereby further adjusting the position of the skeleton 2, and a support frame 24 is fixedly connected to the adjustment plate 22, and an adjustment screw 25 is rotatably installed in the support frame 24, and the adjustment screw 25 is fixedly connected to the adjustment frame 21. When the adjustment screw 25 rotates, it drives the adjustment frame 21 to slide in the adjustment slot 23, thereby changing the relative position between the adjustment frame 21 and the skeleton 2, wherein a locking nut 27 is meshingly installed on the support frame 24, and a support spring 26 is fixedly connected to the locking nut 27, and the free end of the support spring 26 is fixedly connected to the support frame 24, providing an elastic support system, which can offset or adjust the force or displacement generated by the movement of the adjustment frame 21.

[0038] When the position of the adjusting frame 21 needs to be adjusted, it can be achieved by rotating the adjusting screw 25. Since the adjusting screw 25 is fixedly connected to the adjusting frame 21, rotating the adjusting screw 25 will drive the adjusting frame 21 to slide in the adjusting groove 23. At the same time, since the locking nut 27 is meshed and installed with the support frame 24, and the locking nut 27 is fixedly connected to the support spring 26, the movement of the adjusting frame 21 will be affected by the elastic resistance of the support spring 26. This elastic resistance can provide a buffering effect to prevent the adjusting frame 21 from moving suddenly or causing excessive displacement. When the adjusting frame 21 is moved to the desired position, the adjusting screw 25 can be fixed at the current position by the locking nut 27 to ensure the stability and reliability of the adjusting frame 21. At this time, the support spring 26 is still in a certain compression or tension state, providing additional support and stability for the entire structure.

[0039] In the present invention, before cleaning the belt, it is necessary to adjust the contact angle and position of the scraper head 212 with the conveyor belt. By rotating the adjusting screw 25, the position of the adjusting frame 21 in the adjusting slot 23 can be adjusted, thereby changing the relative position of the scraper head 212 with the conveyor belt. During the adjustment process, attention should be paid to observing the scraping effect of the scraper head 212 to ensure that it can effectively scrape off the residue on the conveyor belt. At the same time, the compression degree of the support spring 26 can also be adjusted to change its support strength for the adjusting frame 21, so that the contact between the scraper head 212 and the conveyor belt is more stable. At the same time, the lifting rod 36 is driven to rise by starting the driving motor 3, so that the scraper head 212 is attached to the surface of the conveyor belt, and the adjusting roller 47 rises synchronously. When the adjusting roller 47 rises, the spring elastic support in the spring sleeve rod 44 makes the adjusting roller 47 adapt to the inclination angle of the belt, and the rotating plate 49 pulls the skeleton 2 to follow the rotation adjustment, so that the scraper head 212 can be accurately adjusted according to the inclination angle of the belt.

[0040] During the belt cleaning process, as the belt moves, the roller 46 rotates. When the lever 48 on the roller 46 rotates with it, this rotational force is converted into linear motion, which is transmitted through the rotating plate 49, the second connecting rod 410 and the pull rod 411, and finally acts on the push plates 52 on both sides of the airbag 53. The reciprocating movement of the push plates 52 in the slide groove 55 directly changes the volume of the airbag 53, thereby realizing the suction and discharge of gas. This process does not require an external power source and is completely dependent on the rotation of the roller 46 itself, reflecting the ingenuity and efficiency of the design. During the inflation stage of the airbag 53, the high-pressure gas quickly enters the cavity in the scraper frame 29 through the air pipe 51 and is ejected at high speed through the air hole 211. This airflow not only enhances the cleaning ability of the scraper head 212, but also enables it to be more It can effectively scrape off the stubborn residue on the conveyor belt, and reduce the friction between the scraper head 212 and the belt through the flushing effect of the airflow, thereby extending the service life. When the airbag 53 is deflated, the waste gas in the scraper frame 29 is extracted through the negative pressure mechanism inside the system to prepare for the next inflation. In addition, the combined design of the adjustment plate 22 and the adjustment frame 21 in the present invention provides great convenience for the position adjustment of the skeleton 2. The user only needs to rotate the adjustment screw 25 to smoothly adjust the position of the adjustment frame 21 in the adjustment groove 23 through the elastic buffering effect of the support spring 26. This design not only improves the accuracy and stability of the adjustment, but also enables the entire cleaner to better adapt to conveyor belts of different widths or inclination angles, thereby enhancing its versatility and practicality.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
