Description

Technical Field

[0001] This invention relates to the field of concrete brick production technology, specifically to a concrete brick production and molding device and its usage method. Background Technology

[0002] Concrete bricks are a new type of building material that is lightweight, porous, has good thermal insulation and fire resistance, can be nailed, sawed, and planed, and has a certain earthquake resistance. China began producing this product as early as the early 1930s and it has been widely used in high-rise frame structure buildings. It is an excellent new building material with advantages such as environmental protection. The production process of concrete bricks requires mixing raw materials such as concrete, and then pouring the fully mixed concrete into molds to form the bricks.

[0003] Referring to a Chinese patent, a device for producing and molding concrete blocks (Publication No.: CN113119284B, Publication Date: 2022-05-24), this patent solves the problems of insufficient compressive strength of the side plates of existing concrete molding molds, and the difficulty in opening the side plates, which makes it difficult to remove the molded concrete blocks and facilitates subsequent cutting. Furthermore, currently, after the concrete blocks are removed from the mold, holes need to be drilled in the blocks depending on their actual use environment. This is not only cumbersome, labor-intensive, and costly, but drilling after molding may also affect the strength and quality of the concrete blocks. However, the aforementioned patent still has the following shortcomings:

[0004] 1. During the concrete extrusion process, excess concrete overflows from the top of the side plate of the mold. However, this patent lacks an automatic scraping and cleaning mechanism, so the excess concrete on the top of the concrete brick can only be scraped off manually with a scraper, which is inefficient, time-consuming and labor-intensive.

[0005] 2. The lack of a collection device for overflowing concrete from above leads to concrete waste and increases production costs. Moreover, the overflowing concrete easily falls into the groove and further adheres to the surface of the double-acting screw. Concrete adhering to the threads of the double-acting screw affects the movement of the two side plates driven by the double-acting screw. Since the double-acting screw is set in the groove of the bottom plate, it is difficult to effectively clean its surface.

[0006] To address this issue, we propose a concrete brick production and molding device and its usage method. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a concrete brick production and molding device and its usage method, which solves the problems of lacking an automatic scraping and cleaning mechanism, requiring manual scraping of excess concrete from the top of the concrete brick, resulting in low cleaning efficiency, time and labor costs, lack of collection device for overflowing concrete, and inconvenience in cleaning concrete adhering to the threads of the bidirectional screw.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a concrete brick production and molding device, comprising a base plate, two fixing plates fixed to the top of the base plate, a groove formed on the top of the base plate, a first bidirectional lead screw rotatably connected between opposite sides of the inner wall of the groove, a first motor fixed to one side of the base plate, the output end of the first motor being fixed to one end of the first bidirectional lead screw via a coupling, connecting ears threaded to both sides of the outer surface of the first bidirectional lead screw, the outer surfaces of the two connecting ears being slidably connected to the inner surface of the groove, two side plates slidably connected to the top of the base plate, the bottoms of the two side plates being connected to the top of the connecting ears. The two side plates are fixed, and their opposite sides are in contact with and pressed against the side of the two fixed plates that is away from each other. A round rod is provided on the opposite side of each of the two side plates, and the opposite ends of the round rods are in contact with each other. An automatic scraping and cleaning mechanism is provided on one side of the top of the bottom plate, and a collection box is slidably connected to the other side of the top of the bottom plate. A concrete lifting assembly is provided inside the collection box. Two horizontal bars are fixed to the bottom of the collection box. Two grooves are opened on one side of the top of the bottom plate. The bottoms of the two horizontal bars pass through the grooves and extend into the grooves. The outer surfaces of the two horizontal bars are slidably connected to the inner surfaces of the grooves. A material blocking assembly is provided on the opposite side of each of the two side plates.

[0009] Preferably, the automatic scraping and cleaning mechanism includes a connecting plate fixed to one side of the fixed plate, a rack slidably connected to the top of the connecting plate, and a rotating rod rotatably connected to the top of the connecting plate.

[0010] Preferably, a gear is fixed to the top of the rotating rod, the teeth of the gear meshing with the teeth of the rack, and a second motor is fixed to the bottom of the connecting plate, the output end of the second motor being fixed to the bottom end of the rotating rod via a coupling.

[0011] Preferably, a pusher plate is fixed to one side of the rack, and the bottom of the pusher plate is slidably connected to the top of the side plate and the fixed plate.

[0012] Preferably, the concrete lifting assembly includes a second bidirectional screw rotatably connected between opposite sides of the inner wall of the collection box, one end of the second bidirectional screw passing through the collection box and extending to the outside of the collection box.

[0013] Preferably, one end of the second bidirectional lead screw is fixed with a rotating handle, a top plate is slidably connected between the inner walls of the collection box, and movable plates are threadedly connected to both sides of the outer surface of the second bidirectional lead screw.

[0014] Preferably, the outer surfaces of both movable plates are slidably connected to the inner surface of the collection box, and the tops of both movable plates are rotatably connected to movable rods, the tops of both movable rods being rotatably connected to the bottom of the top plate.

[0015] Preferably, the baffle assembly includes U-shaped baffles fixed to the opposite side of the two side plates. Horizontal grooves are provided on both sides of the top of the bottom plate. The bottoms of the two U-shaped baffles penetrate the horizontal grooves and extend into the interior of the grooves. The outer surfaces of the two U-shaped baffles are slidably connected to the inner surface of the horizontal grooves.

[0016] This invention also discloses a method for using a concrete brick production and molding device, specifically including the following steps:

[0017] S1. First, place the concrete material on the top of the base plate, then start the first motor so that the first motor drives the first bidirectional screw to rotate. At the same time, the first bidirectional screw drives the two connecting ears and the side plates to move in opposite directions. Finally, the two side plates and the two fixed plates work together to extrude and mold the concrete material. At the same time, the two round rods move in opposite directions to drill holes in the concrete.

[0018] S2. Further start the second motor, so that the second motor drives the rotating rod to rotate, and at the same time the rotating rod drives the gear to rotate, and at the same time the gear drives the rack to slide backward, and at the same time the rack drives the pusher plate to slide backward, and at the same time the pusher plate pushes the excess overflowing concrete, and further pushes the concrete into the collection box for collection.

[0019] S3. When it is necessary to remove the concrete, turn the handle to make the second double-acting screw rotate. At the same time, the second double-acting screw drives the two moving plates to slide in opposite directions. Simultaneously, the two moving plates drive the two movable rods to rotate and rise. At the same time, the two rotating rods drive the top plate to slide upward. Finally, the top plate pushes out the collected concrete.

[0020] Beneficial effects

[0021] This invention provides a concrete brick production and molding apparatus and its method of use. Compared with the prior art, it has the following advantages:

[0022] (1) The concrete brick production and molding device and its usage method, through the setting of the automatic scraping and cleaning mechanism, realize the automatic scraping and cleaning of excess concrete, without the need to manually scrape off the excess concrete with a scraper, with a high degree of automation, saving time and effort, and greatly improving the cleaning efficiency.

[0023] (2) The concrete brick production and molding device and its usage method, through the setting of the collection box, the automatic scraping and cleaning mechanism pushes the cleaned concrete into the inside of the collection box, completing the centralized collection of excess concrete, avoiding concrete waste, reducing production costs, and through the setting of the concrete lifting component, it is convenient to quickly lift the collected concrete, making it easier to remove the concrete, which is very practical.

[0024] (3) The concrete brick production and molding device and its usage method, by inserting two horizontal bars at the bottom of the collection box into the chute, the horizontal bars slide along the inside of the chute. Through the setting of the horizontal bars and the chute, the collection box can slide freely, which facilitates the disassembly and assembly between the collection box and the bottom plate. Moreover, it realizes the limitation of the collection box, which can be aligned with the fixed plate, so that the pusher plate can be accurately pushed into the collection box during the scraping process.

[0025] (4) The concrete brick production and molding device and its usage method, by moving the two side plates in opposite directions, the two side plates drive the two U-shaped baffles to slide in opposite directions along the inner surface of the transverse groove. Finally, the two U-shaped baffles block the groove. By setting the material blocking component, excess concrete is prevented from overflowing from the left and right sides and falling into the groove during the scraping process of the pusher plate. This further avoids concrete sticking to the thread surface of the first bidirectional screw, so that the first bidirectional screw can work normally without cleaning it. Attached Figure Description

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.

[0034] This invention provides two technical solutions, specifically including the following embodiments:

[0035] Example 1

[0036] Please see Figure 1-4 , Figure 6A concrete brick production and molding device includes a base plate 1, with two fixed plates 2 fixed to the top of the base plate 1. A groove 3 is formed in the top of the base plate 1, and a first bidirectional lead screw 4 is rotatably connected between opposite sides of the inner wall of the groove 3. The surface of the first bidirectional lead screw 4 is engraved with two sections of threads with opposite helical directions. The central part of the first bidirectional lead screw 4 is smooth. When the first bidirectional lead screw 4 rotates, it can drive two connecting ears 6 to move in opposite directions. A first motor 5 is fixed to one side of the base plate 1. The first motor 5 is a three-phase asynchronous motor, capable of forward and reverse rotation, controlled by an external switch, and electrically connected to an external power supply. The output end of the first motor 5 is fixed to one end of the first bidirectional lead screw 4 via a coupling. Connecting ears 6 are threadedly connected to both sides of the outer surface of the first bidirectional lead screw 4. The outer surfaces of both connecting ears 6 are slidably connected to the inner surface of the groove 3. Two side plates 7 are slidably connected to the top of the base plate 1. When the two side plates 7 move in opposite directions... The concrete raw material can be extruded and molded. The bottom of the two side plates 7 is fixed to the top of the connecting ear 6. The opposite sides of the two side plates 7 are in contact with the side away from the two fixed plates 2 and are extruded. The opposite sides of the two side plates 7 are provided with round rods 8, which can drill holes in the concrete raw material. The opposite ends of the round rods 8 are in contact. An automatic scraping and cleaning mechanism 9 is provided on one side of the top of the bottom plate 1. A collection box 10 is slidably connected to the other side of the top of the bottom plate 1. The collection box 10 can collect the excess concrete pushed down by the pusher plate 96. A concrete lifting component 11 is provided inside the collection box 10. Two horizontal bars 12 are fixed to the bottom of the collection box 10. Two grooves 13 are opened on one side of the top of the bottom plate 1.

The outer surfaces of the two horizontal bars 12 are slidably connected to the inner surfaces of the grooves 13. A baffle component 14 is provided on the side away from the two side plates 7.

[0037] The automatic scraping and cleaning mechanism 9 includes a connecting plate 91 fixed to one side of the fixed plate 2, a rack 92 slidably connected to the top of the connecting plate 91, and a rotating rod 93 rotatably connected to the top of the connecting plate 91.

The second motor 95 is a three-phase asynchronous motor that can rotate in both directions. It is controlled by an external switch and is electrically connected to an external power supply. The output end of the second motor 95 is fixed to the bottom end of the rotating rod 93 through a coupling.

[0039] A pusher plate 96 is fixed on one side of the rack 92. The pusher plate 96 can scrape away the excess concrete pushed out by the side plate 7. The bottom of the pusher plate 96 is slidably connected to the top of the side plate 7 and the fixed plate 2. With the automatic scraping and cleaning mechanism 9, the excess overflowing concrete can be automatically scraped and cleaned. There is no need to manually scrape off the excess concrete with a scraper. The degree of automation is high, saving time and effort and greatly improving the cleaning efficiency.

[0040] The material blocking assembly 14 includes a U-shaped baffle 141 fixed to one of the two side plates 7 on opposite sides. The U-shaped baffle 141 blocks the groove 3 as the two side plates 7 move in opposite directions. The U-shaped baffle 141 prevents overflowing concrete from falling into the groove 3. Horizontal grooves 142 are provided on both sides of the top of the bottom plate 1. The bottom of both U-shaped baffles 141 penetrates the horizontal grooves 142 and extends into the interior of the horizontal grooves 142. The outer surfaces of both U-shaped baffles 141 are slidably connected to the inner surfaces of the horizontal grooves 142. By setting up the material blocking assembly 14, excess concrete is prevented from overflowing from the left and right sides and falling into the groove 3 during the scraping process of the pusher plate 96. This further prevents concrete from adhering to the threaded surface of the first bidirectional screw 4, thus allowing the first bidirectional screw 4 to work normally without the need for cleaning.

[0041] This invention also discloses a method for using a concrete brick production and molding device, specifically including the following steps:

[0042] S1. First, place the concrete material on the top of the base plate 1, and then start the first motor 5 so that the first motor 5 drives the first bidirectional screw 4 to rotate. At the same time, the first bidirectional screw 4 drives the two connecting ears 6 and the side plates 7 to move in opposite directions. Finally, the two side plates 7 and the two fixed plates 2 cooperate to extrude and mold the concrete material. At the same time, the two round rods 8 drill holes in the concrete when they move in opposite directions.

[0043] S2. Further start the second motor 95, so that the second motor 95 drives the rotating rod 93 to rotate. At the same time, the rotating rod 93 drives the gear 94 to rotate. At the same time, the gear 94 drives the rack 92 to slide backward. At the same time, the rack 92 drives the pusher plate 96 to slide backward. At the same time, the pusher plate 96 pushes the excess overflowing concrete and further pushes the concrete into the collection box 10 for collection.

[0044] S3. When it is necessary to remove the concrete, rotate the rotating handle 112 to drive the second bidirectional screw 111 to rotate. At the same time, the second bidirectional screw 111 drives the two moving plates 114 to slide in opposite directions. Simultaneously, the two moving plates 114 drive the two movable rods 115 to rotate and rise. At the same time, the two rotating rods 93 drive the top plate 113 to slide upward. Finally, the top plate 113 pushes out the collected concrete.

[0046] Based on Example 1, see Figure 5 As shown

[0047] The concrete lifting assembly 11 includes a second bidirectional screw 111 rotatably connected between opposite sides of the inner wall of the collection box 10, one end of which passes through the collection box 10 and extends to the outside of the collection box 10.

[0048] One end of the second bidirectional screw 111 is fixed with a rotating handle 112. A top plate 113 is slidably connected between the inner walls of the collection box 10.
