Technical Field

[0001] This utility model relates to the field of hollow brick forming technology, specifically to a hollow brick forming equipment. Background Technology

[0002] Hollow brick forming refers to the process of shaping prepared raw materials (such as clay, shale, concrete mixture, etc.) into brick blanks with specified external dimensions and internal pore structure through specific processes and equipment. This is one of the most core and critical processes in hollow brick production.

[0003] Chinese patent publication number CN218576577U discloses a hollow brick forming device for easy brick production, including a base, a mold assembly on top of the base, a support leg fixed to the bottom of the base, a fixed frame fixed to one side of the mold assembly at the upper end of the base, and a pressure plate below the fixed frame; a scraper on one side of the fixed frame, a moving component on the side of the scraper near the fixed frame, limit plates fixed on both sides of the fixed frame away from the moving component, and a collection trough for collecting raw materials on the side of the mold assembly away from the scraper. This invention, by setting up a scraper, uses a second electric push rod to drive the scraper to move, allowing the scraper to scrape off excess raw materials on the left and right molds, ensuring that the top of the raw materials inside the left and right molds is in a flat state, thereby increasing the quality of the formed bricks. Simultaneously, the collection trough allows for the collection of scraped raw materials, avoiding waste.

[0004] In the aforementioned prior art, excess raw materials can be scraped off during the processing by scraper and limiting plate. Although excess hollow brick raw materials can be scraped off, the combined structure of scraper and limiting plate is a large opening structure. Excess hollow brick raw materials may still diffuse outward from the opening and fall to the outside. Therefore, a hollow brick forming device is proposed. Utility Model Content

[0019] 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.

[0020] Please see Figure 1 and Figure 2 A hollow brick forming device includes a base 10, which is supported by its support legs. A bracket 11 and a limiting mold 30 are installed on the upper end of the base 10. A processing component is installed inside the bracket 11. The processing component includes an electric push rod 20 fixed to the bottom of the inner end of the bracket 11. The output end of the electric push rod 20 is provided with a pressure plate 21. The pressure plate 21 processes and forms the hollow brick raw material. The pressure plate 21 is detachably connected to the output rod of the electric push rod 20 by a fastener through a connecting pin 22 at its top. The electric push rod 20 drives the pressure plate 21 to rise and fall. The limiting mold 30 consists of left and right molds. The limiting mold 30 in the closed state limits the hollow brick raw material to be formed, providing processing space. The limiting mold 30 consists of left and right molds, each equipped with a transmission frame 31. The transmission frames 31 of the left and right molds are arranged opposite each other, located at the ends of the left and right molds that are far apart from each other. A driving component 1, which is driven and connected to the limiting mold 30, is installed at the bottom of the base 10. The driving component 1 includes a dual-output shaft motor 40 installed at the bottom of the base 10. The dual-output shaft motor 40 is fixed to the bottom of the base 10 by its mounting base. The dual-output shaft motor 40 is provided with a protective shell fixed to the bottom of the base 10. The fixing method between the dual-output shaft motor 40 and the corresponding protective shell and the base 10 includes, but is not limited to, bolt fixing. The two output shafts of the dual-output shaft motor 40 are respectively threaded to the corresponding transmission frames 31 of the driving rods 41. The ends of the two driving rods 41 that are far apart from each other are respectively fixed to the bottom of the base 10. The bracket 12 is rotatably connected to further stabilize the drive rod 41 and keep the drive rod 41 stable. During the operation of the dual-output shaft motor 40, it can drive the drive rods 41 on both sides to rotate. The base 10 has a limit groove corresponding to the transmission frame 31 to provide space for the transmission frame 31 to slide and limit the transmission frame 31. During the rotation of the drive rod 41, it can drive the corresponding transmission frame 31 to slide. The external threads of the two drive rods 41 are opposite. When the dual-output shaft motor 40 is started, it can drive the drive rods 41 on both sides to rotate at the same time, thereby driving the corresponding transmission frame 31 of each drive rod 41 to slide, causing the left and right molds to move closer or further apart. When the limiting mold 30 is in the closed state, the left and right molds are in a docking state.

[0021] Please see Figure 3-5The embodiments proposed in this application include: a hollow brick forming device, which further includes a cleaning structure 50 that is contacted on the upper side of the limiting mold 30. The cleaning structure 50 is a frame with a closed perimeter, and its lower opening is adapted to the specifications of the upper opening of the limiting mold 30. The cleaning structure 50 can scrape off the excess raw material squeezed out by the pressure plate 21 in the limiting mold 30 during the forming of the hollow brick. The side of the cleaning structure 50 located away from the limiting mold 30 at its lower opening is connected to the bottom plate to form a collection groove 51. The excess raw material squeezed out by the pressure plate 21 is squeezed and collected into the collection groove 51. The inner end of the bracket 11 is equipped with a second driving component and a scraping component on opposite sides. The second driving component and the scraping component are detachably connected to the cleaning structure 50. The second driving component can drive the movement of the cleaning structure 50. One end of the scraping component is placed in the cleaning structure 50 to push out and scrape off the excess raw material accumulated in the limiting mold 30, so as to avoid the accumulation of a large amount of hollow brick raw material in the limiting mold 30. Specifically, the second driving component includes an electric push rod 80 fixed to the inner wall of one side of the bracket 11. The output rod of the electric push rod 80 is connected to a push plate 81. After the electric push rod 80 is started, the cleaning structure 50 can be pushed by the push plate 81. The sludge scraping assembly includes a scraper 60 located in the collection tank 51. The scraper 60 is in contact with the corresponding surface of the collection tank 51 and the cleaning structure 50. When the cleaning structure 50 moves towards the side closer to the sludge scraping assembly, the scraper 60 can push out and scrape off the excess material accumulated in the limiting mold 30. The second component includes several connectors 61 fixed to the inner wall of the other side of the bracket 11. Each connector 61 is detachably connected to the scraper 60 with a support rod 62. The support rod 62 passes through the cleaning structure 50, and its two ends are threadedly connected to the corresponding scraper 60 and connector 61, respectively, which facilitates the overall assembly and disassembly of the sludge scraping assembly. Insert plates 811 are slidably arranged on both sides of the push plate 81. Two docking blocks 52 are fixedly installed on the outer end of the cleaning structure 50 corresponding to the side of the drive component 2. The docking blocks 52 correspond one-to-one with the insert plates 811 and have slots 521 inside. When the drive component 2 and the cleaning structure 50 are connected, the insert plates 811 engage with the corresponding slots 521, thereby causing the output rod of the electric push rod 2 80 to push and pull the cleaning structure 50 during the extension and retraction process. The push plate 81 has limiting grooves 812 at both ends corresponding to the insert plates 811, which provide sliding space and limiting function for the insert plates 811. The limiting grooves 812 have a reset spring 813 inside to abut the insert plates 811. The spring force of the reset spring 813 can push the insert plates 811 outward from the push plate 81, so that the insert plates 811 can automatically engage with the slots 521 of the corresponding docking blocks 52, maintaining the connection between the drive component 2 and the cleaning structure 50.

[0022] Furthermore, support frames 70 are provided on both sides of the sludge scraping assembly. The two ends of the support frames 70 are fixed to the bracket 11 and the base 10, respectively. Several rollers 71 are rotatably arranged on the inner side of the upper end of the support frame 70. The outer end of the cleaning structure 50 is provided with docking blocks 52 corresponding to the two sides of the support frame 70. When the cleaning structure 50 moves, the docking blocks 52 contact the rollers 71 on the corresponding side. The two support frames 70 support the two sides of the cleaning structure 50 during the movement, making the movement of the cleaning structure 50 more stable. This reduces the stress load on the output rod of the electric push rod 80 and the support rod 62 connected to the scraper 60 during the movement of the cleaning structure 50, making the structure more stable and improving the service life of parts and components. In addition, during the movement of the cleaning structure 50, the contact between the docking blocks 52 and the rollers 71, through the transmission of the rollers 71, can also reduce the friction when the two are in contact.

[0023] Furthermore, such as Figure 4 As shown, the connector 61 has a threaded groove 601 adapted to the support rod 62. When the entire sludge scraper assembly is in the installation state, that is, when the support rod 62 and the connector 61 are in the installation state, there is extra gap in the threaded groove 601 to provide space for the support rod 62 to rotate and retract. This is suitable for situations where the entire sludge scraper assembly needs to be disassembled and assembled.

[0024] Please see Figure 6 In a further embodiment, the bottom of the scraper assembly is provided with a discharge trough 90 formed on the base 10. The inner wall width of the discharge trough 90 is equal to or greater than the corresponding inner width of the limiting mold 30 in the sealing state (it can also be the length depending on the viewing angle under different conditions). The discharge trough 90 is positioned close to the limiting mold 30 and is located on the side near the collection trough 51, so as to receive and discharge the empty brick raw material that was originally located in the collection trough 51 and discharged from the cleaning structure 50 by the scraper 60 pushing out and scraping it through the discharge trough 90. The upper end of the discharge trough 90 is provided with A receiving frame 91 is fixed on the base 10. The receiving frame 91 is a three-sided frame with the opening facing the limiting mold 30. The inner wall of the receiving frame 91 is sloping, so that the opening at the top of the receiving frame 91 is slightly larger than the opening at the bottom, so as to better receive the hollow brick raw material discharged from the cleaning structure 50. At the same time, there is a gap between the inner edge of the bottom of the receiving frame 91 and the outer edge of the discharge trough 90, so that when the collection container is embedded in the discharge trough 90, the top frame of the collection container is supported by the gap between the receiving frame 91 and the discharge trough 90, which facilitates the installation of the collection container.

[0025] Working principle: During the use of this molding equipment, after the hollow brick raw material in the limiting mold 30 is processed and shaped by the pressure plate 21 (during the processing, the limiting mold 30 is in a closed state), the electric push rod 80 is activated to drive the cleaning structure 50 to move through the push plate 81. Through the closed frame structure of the cleaning structure 50 and the contact between the cleaning structure 50 and the limiting mold 30, the excess raw material squeezed out by the pressure plate 21 in the limiting mold 30 can be scraped off and collected in the collection trough 51 to prevent the excess raw material from overflowing and falling onto the base 10. At the same time, the scraper 60 pushes out the raw material collected in the collection trough 51 (during this process, the entire scraping assembly is in the installation state), so that the excess raw material is discharged into the collection container at the discharge trough 90.

[0026] After a period of use, a certain amount of hollow brick material may accumulate and adhere inside the cleaning structure 50 and on the scraper 60. Removing the cleaning structure 50 and the scraper 60 will help with better cleaning (e.g., in dead corners). At this time, first rotate the support rod 62 so that one end of the support rod 62 corresponding to the connector 61 is inserted into the threaded groove 601, and then the other end of the support rod 62 is withdrawn from the scraper 60 and the cleaning structure 50. At this time, the sludge scraping assembly is disassembled and the scraper 60 can be removed. Then, press the two insert plates 811 towards the position close to the push plate 81, and then the insert plates 811 will lose the engagement with the corresponding docking block 52. At this time, the drive component two and the cleaning structure 50 are disassembled and the cleaning structure 50 can be removed. After both the scraper 60 and the cleaning structure 50 are disassembled, the residual material can be cleaned.

[0027] The distance that the electric push rod 280 drives the output rod to move is preset in advance, so as not to cause the scraper 60 to excessively squeeze the inner wall of the cleaning structure 50. The control method of the electric push rod 280 can use existing technology. For example, the control method can be a button controller that is electrically connected by a cable, but there are no restrictions on the specific control method, as long as it conforms to industry standards.

[0028] The connection methods of the output rod of the electric push rod 20 and the connecting pin 22, the connection method of the output end of the dual-shaft motor 40 and the drive rod 41, and the connection method of the output rod of the electric push rod 80 and the push plate 81 can all adopt existing methods, referring to the conventional professional standards of industrial machinery.
