Detailed Implementation

[0017] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] First Embodiment In the field of construction waste recycling, die extrusion molding technology, as a core process for producing recycled building materials, commonly suffers from quality defects caused by waste residue. Specifically, construction waste remains on the upper surface of the side wall of the lower die 2, affecting the fit between the lower die 2 and the upper die 3, significantly reducing the quality of the manufactured cement products. However, traditional techniques do not thoroughly clean the top of the lower die 2, resulting in waste. To improve the quality and precision of the pressed products and prevent waste accumulation from affecting the quality of cement products made from construction waste, [further details are needed]. Figure 1 - Figure 2 This embodiment provides an automatic cleaning and pressing device, which consists of a base plate 1, a lower mold 2, an upper mold 3, and a cleaning mechanism 4. The schematic diagram shows the state after cleaning the residual construction waste on the upper surface of the side wall of the lower mold 2. The lower mold 2 is set on the top of the base plate 1, and the upper mold 3 is set on the top of the lower mold 2. A pressing drive is set on the top of the upper mold 3 to drive the upper mold 3 to move downward and press the waste in the lower mold 2, thereby making building cement products. A cover for protecting the cleaning mechanism 4 is also installed on the upper mold 3.

[0019] To ensure more thorough waste removal and prevent waste residue on the upper surface of the side wall of the lower mold 2, a cleaning mechanism 4 for cleaning residual construction waste on the upper surface of the side wall of the lower mold 2 is provided on the top of the upper mold 3. The cleaning mechanism 4 includes a top plate 41 fixed to the top of the upper mold 3 and movable scrapers 42 respectively arranged around the top plate 41. The top of the movable scrapers 42 is rotatably connected to the edge of the top plate 41. A gear shaft 44 is fixed to the top of one of the movable scrapers 42. When the gear shaft 44 rotates, it drives the movable scraper 42 at its bottom to rotate. A limiting horizontal plate 43 is fixed on the gear shaft 44. A limiting vertical plate 45 fixed to the base plate 1 is provided at the bottom end of the limiting horizontal plate 43. When the limiting horizontal plate 43 moves downward, it is blocked by the limiting vertical plate 45, causing the limiting horizontal plate 43 to drive the gear shaft 44 to rotate. A lifting rod 46 is provided between two adjacent movable scrapers 42. The four movable scrapers 42 and the lifting rod 46 are initially set to a vertical state.

[0020] As the bottom ends of the four movable scrapers 42 and the lifting rods 46 contact the top of the lower mold 2, the limiting horizontal plate 43 contacts the limiting vertical plate 45, thereby causing the gear shaft 44 to rotate. The gear shaft 44 drives the movable scrapers 42 on it to rotate. At the same time, the gear shaft 44 drives the four lifting rods 46 to rotate through the transmission structure, which in turn drives the four movable scrapers 42 to rotate. The four movable scrapers 42 scrape off the waste material around the top of the lower mold 2, while the four lifting rods 46 scrape off the waste material at the four corners of the top of the lower mold 2. This can complete the efficient cleaning in a short time without affecting the pressing process of the product.

[0021] Second Embodiment To quickly clean the residual waste material on the upper surface of the side wall of the lower mold 2, and to improve the cleaning effect, refer to Figure 3 - Figure 4 In this embodiment, a transmission assembly 48 is provided on the top plate 41 for driving the gear shaft 44 to rotate and driving the lifting rod 46 to rotate. Specifically, the transmission assembly 48 includes a rack 481 slidably disposed on the top of the top plate 41. A limiting buckle fixed to the top plate 41 is slidably disposed in the middle of the rack 481, so that the rack 481 slides stably on the top plate 41. One end of the rack 481 is meshed with the gear shaft 44 at its bottom, and a transmission gear 482 is meshed with the top of the end of the rack 481 away from the gear shaft 44. A horizontal shaft 483 is fixed at the center of the transmission gear 482 and rotates with the top plate 41 through a bearing seat. A horizontal shaft 484 is rotatably mounted at the four corners of the top of the top plate 41 through bearing seats. A bevel gear set 485 is driven at one end of the horizontal shaft 484 and is connected to the top of the lifting rod 46. The bevel gear set 485 consists of two bevel gears. The bevel gear at one end of the horizontal shaft 484 meshes with the bevel gear on one side of the top of the lifting rod 46, so that the lifting rod 46 can rotate around the axis of the bevel gear.

[0022] Both ends of the horizontal shaft 483 are provided with bevel gear sets 486. The horizontal shaft 483 is connected to two adjacent horizontal shafts 484 via the bevel gear sets 486. The bevel gear sets 486 consist of three bevel gears. The bevel gears at the end of the horizontal shaft 483 mesh with the bevel gears at one end of each of the two horizontal shafts 484. The end of the rack 481 away from the gear shaft 44 is provided with a movable seat 487 that slides with the top plate 41. A return spring 488 is sleeved on one side of the movable seat 487. One end of 488 is fixed with a limiting seat 489 that is fixed to the top plate 41. When the rack 481 moves, it pushes the movable seat 487 to move. The movable seat 487 squeezes the return spring 488, and the return spring 488 is compressed due to elastic deformation. After the compression is completed, the limiting horizontal plate 43 lacks the clamping of the limiting vertical plate 45. The movable scraper 42 rotates downward due to gravity. At the same time, the return spring 488 recovers its elastic deformation, pushes the rack 481 to move, and then pushes the movable scraper 42 to quickly return to the vertical state.

[0023] When the limiting horizontal plate 43 rotates upward, it drives the gear shaft 44 to rotate. The gear shaft 44 drives the movable scraper 42 at its bottom to rotate. At the same time, the gear shaft 44 drives the rack 481 meshing with it to move. The rack 481 drives the transmission gear 482 at one end to rotate. The transmission gear 482 drives the horizontal shaft 483 at its axis to rotate. The horizontal shaft 483 drives the four horizontal shafts 484 to rotate through the bevel gear set 486 at both ends. The horizontal shafts 484 drive the lifting rod 46 to rotate through the bevel gear set 485, which in turn drives the other three movable scrapers 42 to rotate, scraping off the waste material on the upper surface of the side wall of the lower mold 2. This allows for thorough cleaning while pressing cement products, improving the practicality of the pressing device.

[0024] Third Embodiment To ensure that the four movable scrapers 42 and the lifting rod 46 can rotate simultaneously and stably, and to ensure more thorough waste removal, refer to... Figure 2 and Figure 5 In this embodiment, a connecting component 47 is provided at the bottom of the lifting rod 46 for simultaneously lifting the four movable scrapers 42 and cleaning the waste material at the top four corners of the lower mold 2 through the lifting rod 46. Specifically, the connecting component 47 includes strip grooves 471 respectively opened at both ends of the movable scrapers 42 except at the bottom of the gear shaft 44. A connecting rod 472 is fixed on one side of the middle part of the lifting rod 46. Telescopic couplings 473 are fixed on both sides of the connecting rod 472. One end of the telescopic coupling 473 is slidably connected to the strip groove 471. A support column 474 fixed to the top plate 41 is rotatably provided at the middle of the top of the four lifting rods 46.

[0025] When the lifting rod 46 rotates around the axis of the bevel gear, it drives the connecting rod 472 to rotate. The connecting rod 472 drives the telescopic couplings 473 on both sides to rotate simultaneously. The telescopic couplings 473 drive the movable scraper 42 at one end to rotate, thereby making the four movable scrapers 42 and the lifting rod 46 rotate stably at a certain angle.

[0026] The present invention drives the gear shaft 44 to rotate through the transmission component 48 and drives the lifting rod 46 to rotate. At the same time, it works with the connecting component 47 to lift the four movable scrapers 42 and clean the waste at the top four corners of the lower mold 2 through the lifting rod 46, ensuring more thorough waste cleaning and avoiding waste residue on the upper surface of the side wall of the lower mold 2.

[0027] During use, the upper mold 3 moves downward, pressing the construction waste inside the lower mold 2 into shape. When the upper mold 3 moves the top plate 41 downward, the movable scraper 42 contacts the top of the lower mold 2, and at the same time, the limiting horizontal plate 43 contacts the limiting vertical plate 45. The limiting horizontal plate 43 is fixed, causing the gear shaft 44 to rotate upward. The gear shaft 44 drives the movable scraper 42 at its bottom to rotate, and at the same time, the gear shaft 44 drives the rack 481 meshing with it to move. The rack 481 drives the transmission gear 482 at one end to rotate, and the transmission gear 482 drives its shaft to rotate. The horizontal shaft 483 at the center rotates, and the horizontal shaft 483 drives the four horizontal shafts 484 to rotate through the bevel gear sets 486 at both ends. The horizontal shafts 484 drive the lifting rod 46 to rotate around the axis of the bevel gear through the bevel gear set 485. The lifting rod 46 drives the connecting rod 472 to rotate. The connecting rod 472 drives the telescopic couplings 473 on both sides to rotate simultaneously. The telescopic couplings 473 drive the movable scraper 42 at one end to rotate, thereby driving the four movable scrapers 42 and the lifting rod 46 to rotate together, scraping off the waste material on the upper surface of the side wall of the lower mold 2.

[0028] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0029] 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 variations can 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.
