Description

Technical Field

[0001] This invention relates to the field of brick kiln processing equipment technology, and in particular to a self-cleaning brick kiln roller mechanism. Background Technology

[0002] The three-dimensional brick kiln roller cleaning equipment is a specialized machine used to clean the surface of freshly fired bricks. Its core function is to use a roller covered with fiber material to roll on the high-temperature brick surface to crush and remove the debris and impurities adhering to the bricks.

[0003] However, existing equipment often encounters the following problems in use: Traditional three-dimensional brick kiln roller cleaning equipment uses a robotic arm to push the entire large equipment so that the cleaning end rollers push the debris on the surface of rows of neatly fired bricks to achieve the purpose of removal. However, the rollers themselves will absorb some gravel and sand particles due to their fibrous material. At this time, manual cleaning is required, which is not only time-consuming and labor-intensive, but also makes the cleaning operation uninterrupted. It is necessary to stop the machine from time to time to clean the rollers, which affects the work efficiency. Summary of the Invention

The design of this invention aims to solve the problem that traditional three-dimensional brick kiln roller cleaning equipment uses a robotic arm to push the entire large device, so that the cleaning end roller of the device rolls on the surface of rows of neatly fired bricks to remove debris. However, the roller itself, due to its fibrous material, will adsorb some gravel and sand particles, which requires manual cleaning. This is not only time-consuming and labor-intensive, but also makes the cleaning operation uninterrupted, requiring frequent stops for roller cleaning, thus affecting work efficiency.

Simultaneously, the positioned reciprocating motion mechanism starts, its main motor driving the sliding frame to reciprocate via a connecting rod, which in turn causes the threaded rod to push the sleeve and drive gear in both forward and reverse directions, ultimately driving the reciprocating sliding plate equipped with a scraper to reciprocate linearly along the guide rail, automatically scraping away the gravel and sand particles adsorbed on the surface of the tilted roller. The entire process requires no disassembly of the roller or stopping the machine, achieving online, continuous, and automated cleaning operations. Attached Figure Description

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0057] like Figure 1-5 As shown, the present invention provides a self-cleaning brick kiln roller mechanism, which includes a three-dimensional frame 1, an extended frame 2, a base 3, a reciprocating motion mechanism 4, a guide rail 5, a vertical base plate 6, and a roller positioning mechanism 7.

[0058] The extension frame 2 is flush with the main frame, expanding the load-bearing area of ​​the main frame and forming a dedicated operating platform area. The extension frame 2 is fixedly connected to one side of the main frame. This fixed connection ensures that the extension frame 2 and the main frame are integrated, guaranteeing the rigidity and stability of the entire support structure. The base 3 is located on the top surface of the extension frame 2, providing a higher and flatter dedicated mounting surface for supporting and positioning the subsequent reciprocating motion mechanism 4. Two sets of reciprocating motion mechanisms 4 are provided, symmetrically arranged about the cross-section of the extension frame 2. This symmetrical arrangement allows for simultaneous cleaning from both sides of the brick kiln roller 76, ensuring balanced cleaning force and preventing unilateral force from causing roller 76 to shift or incomplete cleaning.

[0059] In this invention, the guide rail 5 is horizontally positioned on the seat, and one side of the vertical base plate 6 is fixedly connected to the extension end of the extension frame 2. This design aims to create a vertical mounting surface at the end of the mechanism for supporting and fixing the roller 76 positioning system. Furthermore, the vertical base plate 6 is perpendicular to the extension frame 2. This perpendicular relationship ensures that the mounting axis of the roller 76 remains parallel to the movement direction of the scraper 49, creating conditions for effective cleaning contact. The roller positioning mechanism 7 is located on the surface of the vertical base plate 6. The brick kiln roller 76 to be cleaned is installed and positioned on this mechanism, enabling the roller 76 to switch between the "working position" and the "cleaning position."

[0060] In this invention, such as Figure 2 As shown, each reciprocating motion mechanism 4 includes a slide 41 whose top-view direction is perpendicular to the guide rail 5. A guide rail 5 fixing frame 42 is located above the slide 41. This arrangement is designed to spatially connect the guide rail 5 with the drive mechanism of the slide 41 below through the fixing frame 42, forming a compact functional unit. The fixing frame 42 is used to fix the guide rail 5, and the fixing frame 42 is mounted inside the slide 41. The purpose of mounting the fixing frame 42 inside the slide 41 is to use the side wall of the slide 41 to limit and provide auxiliary support for the fixing frame 42, thereby enhancing its structural stability. A sliding frame 43 is built into the slide 41. The purpose of being built into the slide 41 is to constrain the sliding frame 43 to only move linearly along the length direction of the slide 41. The sliding frame 43 is slidably connected to the slide 41. The purpose of the sliding connection is to enable the sliding frame 43 to move smoothly back and forth within the slide 41, transmitting driving force.

[0061] In this invention, the linkage 44 is built into the sliding frame 43. This design aims to fix the linkage 44 to the sliding frame 43, allowing the linkage 44 to move together with the sliding frame 43. Connecting slots are provided on both sides of the linkage key. The purpose of these slots is to provide an interface for movable connection with the first connecting rod 410 and the threaded rod 45, for transmitting and converting motion. One end of the threaded rod 45 is fixedly connected to one side of the linkage 44. This fixed connection allows the threaded rod 45 to move linearly synchronously with the linkage 44. The other end of the threaded rod 45 passes through the frame of the fixed frame 42. This through-through design provides a path for the threaded rod 45 to pass through the fixed frame 42 and align it with subsequent threaded fitting components. The sleeve 46 is movably built into the fixed frame 42. This movable design allows the sleeve 46 to rotate freely around its own axis within the fixed frame 42. Furthermore, the threaded rod 45 is threadedly connected to the sleeve 46. The purpose of the threaded connection is to efficiently convert the linear motion of the threaded rod 45 into the rotational motion of the sleeve 46.

[0062] In this invention, such as Figure 2 and Figure 5As shown. The drive gear 47 is sleeved on one end of the sleeve 46. The purpose of this sleeved and fixed design is to allow the drive gear 47 and the sleeve 46 to rotate synchronously, thereby outputting rotational power. The reciprocating slide plate 48 is slidably connected to the guide rail 5. The purpose of this sliding connection is to allow the reciprocating slide plate 48 to perform linear reciprocating motion strictly along the trajectory defined by the guide rail 5. Furthermore, the bottom surface of the reciprocating slide plate 48 is provided with a row of teeth that mesh with the drive gear 47. The purpose of this rack structure and its meshing with the drive gear 47 is to precisely convert the rotational motion of the drive gear 47 into the linear motion of the reciprocating slide plate 48. The scraper 49 is fixed to one side of the reciprocating slide plate 48. The purpose of this fixed connection is to allow the scraper 49 to move synchronously with the reciprocating slide plate 48 and perform a scraping cleaning action on the surface of the roller 76. One end of the first link 410 is movably connected to the other side of the linkage 44. The purpose of this movable connection is to convert the rotational motion output by the main motor 412 into a reciprocating force that pushes or pulls the linkage 44 through the linkage mechanism. One end of the second link 411 is movably connected to the other end of the first link 410. This movable connection constitutes the second hinge point of the linkage mechanism. The purpose of this connection is to transmit and change the motion trajectory and direction. The output end of the main motor 412 is connected to the other end of the second link 411. The purpose of this direct connection is to provide a stable and controllable power source for the entire reciprocating motion mechanism 4.

[0063] In this invention, the roller positioning mechanism 7 includes: two sets of drive frames 71 arranged symmetrically, designed to synchronously drive and support the flipping frame 73 from both ends of the roller 76, ensuring that the roller 76 is stable and does not skew during the flipping process. The output end of the motor 72 is connected to one end of a drive rod 13; this direct connection provides power for the flipping action of the roller 76, allowing the entire flipping frame 73 to be linked by driving the drive rod 13 on one side. The flipping frame 73 is built into the vertical rail 8, designed to constrain the overall movement of the flipping frame 73 within the vertical plane defined by the vertical rail 8, ensuring motion accuracy. Bottom sliders 74 are located on both sides of the bottom of the flipping frame 73 and are slidably connected to the vertical rail 8. The bottom sliders 74 and their slidable connection are designed to bear the main weight of the flipping frame 73 and guide it to slide purely up and down along the vertical rail 8 in the initial stage.

[0064] In this invention, such as Figure 3As shown, the central slider 75 is located on both sides of the middle section of the tilting frame 73. The central slider 75 is slidably connected to the linear rail 10. The purpose of the central slider and its slidable connection with the linear rail 10 / extension rail 11 is to serve as a second support point during the tilting phase and move along a specific track, thereby determining the rotation axis of the tilting frame 73. The roller 76 is installed at the top of the tilting frame 73. The purpose of installing it at the top is that when the tilting frame 73 is in a vertical state, the roller 76 is in the lower working position; when the tilting frame 73 is tilted to a horizontal position, the roller 76 is raised to the upper cleaning position where it contacts the scraper 49.

[0065] Each drive frame 71 includes a vertical rail 8 fixed to one side of the vertical base plate 6. This fixed connection provides a vertical reference track and mounting base for the entire flipping motion. An external rail 9 is C-shaped and integrally formed with the vertical rail 8. This C-shape and integral forming design creates a robust guiding and limiting structure to precisely constrain the movement trajectory of the moving end of the drive rod 13. One end of a linear rail 10 connects to one side of the vertical rail 8. This connection provides a smooth transition channel for the central slider 75 on the flipping frame 73 from the vertical rail 8 to the extension rail 11. The other end of the linear rail 10 does not contact the external rail 9. This disconnection is intentional, designed to provide the flipping frame 73 with freedom to rotate around the end of the extension rail 11 after the central slider 75 enters the extension rail 11, thus avoiding structural interference.

[0066] The extension rail 11 and the straight rail 10 are aligned on a straight line. This straight line design ensures that the center slider 75 of the tilting frame 73 can seamlessly slide from the straight rail 10 into the extension rail 11. One end of the extension rail 11 is integrally formed with the outer rail 9. This integral forming design enhances the structural strength of the end of the extension rail 11, allowing it to reliably serve as the rotation fulcrum for the tilting motion. A positioning slot 12 is formed on the vertical rail 8, located within the C-shaped area of ​​the outer rail 9. The purpose of forming the positioning slot 12 and placing it within the C-shaped rail is to provide a reliable locking point for the movable end of the drive rod 13 after completing the tilting action, locking the tilting frame 73 in the horizontal cleaning position. One end of the drive rod 13 is movably connected to the middle section of the vertical rail 8. This movable connection allows the drive rod 13 to rotate and swing around that point. The other end of the drive rod 13 is a movable end, and the positioning slot 12 is located within the movement trajectory of this movable end. This design aims to ensure that when the drive rod 13 rotates, its movable end can accurately pass through and ultimately embed into the positioning slot 12, achieving mechanical self-locking. The movable end of the drive rod 13 is movably connected to one side of the tilting frame 73. The purpose of this movable connection is to convert the rotational motion of the drive rod 13 into a pushing and pulling action on the tilting frame 73, driving it to complete a combined sliding and tilting motion.

[0067] It should be noted that in the self-cleaning brick kiln roller mechanism designed in this invention, the roller 76 is facing downwards by default. When cleaning is required, the motor sets the motor 72 to rotate 180 degrees. The output end of the motor 72 drives one end of the drive rod 13 to rotate. The movable end of the drive rod 13 pulls the flipping frame 73 to slide downwards. The space constrained by the outer rail 9 is the flipping trajectory of the movable end of the drive rod 13. During the sliding process, the central slider 75 in the middle section of the flipping frame 73 will pass through the straight rail 10 to reach the extension rail 11, until it reaches the end of the extension rail 11. With this as the axis, the bottom slide rail that slides downwards continuously will cause the originally downward-facing end of the flipping frame 73 to drive the roller 76 to flip upwards until the movable end of the drive rod 13 rotates 180 degrees and is embedded in the positioning groove. At this time, the flipping frame 73 is flush with the vertical base plate 6, and the roller 76 has been completely flipped to the top and is in contact with the scraper 49 above. Once the roller 76 contacts the scraper 49, the main motor 412 starts and drives the second connecting rod 411 to rotate. The second connecting rod 411 is driven to rotate one revolution, forming a complete circular trajectory. This circular trajectory is now divided into an upper semicircle and a lower semicircle. In the upper semicircle, the second connecting rod 411 pushes the first connecting rod 410 to move in the direction of the guide rail 5. The first connecting rod 410 pushes the sliding frame 43 to slide in the slide groove 41, thereby causing the linkage 44 to push. The threaded rod 45 on one side continues to penetrate deeper into the sleeve 46. Due to the threaded connection between the two, the sleeve 46 will be fixed due to the torque between the threads. When the fixed frame 42 rotates around its axis, the drive gear 47, which is sleeved at one end of the sleeve 46, will also be driven to rotate. The rotation of the drive gear 47 drives the reciprocating sliding plate 48, which will slide linearly in one direction under the guidance of the guide rail 5. Conversely, when the trajectory enters the lower semicircle, the second connecting rod 411 will drive the first connecting rod 410 to pull back the sliding frame 43, which in turn causes the pulled threaded rod 45 to drive the threaded sleeve 46. The reverse-rotating sleeve 46 will drive the drive gear 47, causing it to drive the reciprocating sliding plate 48 to slide in the opposite direction. In this way, the output end of the main motor 412 rotates one revolution, and the reciprocating sliding plate 48 will drive the scraper 49 to slide back and forth on the guide rail 5. The roller 76 in contact with the scraper 49 will also be scraped off by the scraper 49.

[0068] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
