Description

Technical Field

[0001] This utility model relates to the field of building materials manufacturing technology, specifically a trial molding machine. Background Technology

[0002] In building materials testing, the preparation of concrete test blocks is a crucial step in evaluating concrete performance. Traditional methods of concrete test block preparation typically rely on manual labor, including steps such as mixing concrete, pouring it into molds, transferring the molds, and removing the test blocks. This method is not only labor-intensive and inefficient, but the instability of manual operation also easily leads to inconsistent test block quality, affecting the accuracy of the test results. Furthermore, manual operation also poses certain safety hazards.

[0003] With the development of automation technology, some equipment for making concrete test blocks has appeared on the market. However, most of these devices have only one function and cannot achieve full automation of the process from concrete feeding to test block demolding. Moreover, they are not effective in separating concrete from the inner wall of the mold, making it difficult to meet the needs of efficient and high-quality concrete test block production. Utility Model Content

[0004] In order to overcome the problems existing in the prior art, the purpose of this utility model is to provide a trial molding machine.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a trial molding machine, comprising:

[0006] Tilting hopper mechanism, stirring mechanism, transfer mechanism, mold feeding mechanism, and mold ejection mechanism;

[0007] The tilting hopper mechanism includes a hopper body and a tilting assembly. The hopper body is mounted on the tilting assembly, and the mixing mechanism is mounted on one side of the tilting hopper mechanism. The tilting assembly drives the hopper body to tilt, thereby allowing concrete in the hopper body to be poured in from above the mixing mechanism.

[0008] The transfer mechanism is installed below the mixing mechanism. The transfer mechanism has an inlet end and an outlet end. The mold feeding mechanism is installed on one side of the inlet end, and the mold discharging mechanism is installed on one side of the outlet end. The mold feeding mechanism feeds the mold into the inlet end of the transfer mechanism. The mixing mechanism pours the mixed concrete into the mold. The transfer mechanism transfers the mold containing the concrete from the inlet end to the outlet end. The outlet end feeds the mold containing the concrete into the mold discharging mechanism. The mold discharging mechanism sends the mold containing the concrete out.

[0009] The outlet end is provided with a finishing component, and the finishing component has a finishing panel on the side facing the mold. The finishing panel is inserted into the inner wall of the mold to separate the concrete from the inner wall of the mold.

[0010] Main working principle: This mold-making machine completes the entire process of concrete from raw material input to mold delivery through the coordinated operation of the tilting hopper mechanism, mixing mechanism, transfer mechanism, mold feeding mechanism and mold delivery mechanism. Before the mold is delivered, the concrete is separated from the inner wall of the mold by the finishing component, ensuring that the subsequent test blocks can be taken out smoothly.

[0011] The tilting hopper mechanism consists of a hopper body and a tilting assembly. The hopper body is mounted on the tilting assembly, and the mixing mechanism is installed on one side of the tilting hopper mechanism. Workers pour concrete raw materials into the hopper body. When it is necessary to feed material to the mixing mechanism, the tilting assembly starts operating, causing the hopper body to tilt. Because the mixing mechanism is located on one side of the tilting hopper mechanism, as the hopper body tilts, the concrete inside is poured in from above the mixing mechanism, providing raw materials for subsequent mixing operations.

[0012] The mixing mechanism is installed on one side of the tilting hopper mechanism, with a discharge port located below it, opposite the inlet end of the transfer mechanism. Concrete poured from the tilting hopper mechanism enters the mixing mechanism. The mixing mechanism starts and thoroughly mixes the concrete, ensuring its components are evenly combined. After mixing, the concrete flows out from the discharge port below the mixing mechanism and falls directly into a pre-prepared mold in the transfer mechanism, located below and opposite to its inlet end.

[0013] The formwork feeding mechanism is installed on one side of the inlet end of the transfer mechanism. Workers place the mold containing the concrete to be filled onto the feeding mechanism. The feeding mechanism is activated, sending the mold into the inlet end of the transfer mechanism, positioning the mold to receive the mixed concrete.

[0014] The transfer mechanism is installed below the mixing unit and has an inlet and an outlet. After the mixing unit pours the mixed concrete into the mold located at the inlet, the transfer mechanism begins its operation. It smoothly transfers the mold containing the concrete from the inlet to the outlet. This transfer process ensures that the mold does not shake or tilt during the transfer, guaranteeing a uniform distribution of concrete within the mold.

[0015] The finishing assembly is located at the outlet end of the transfer mechanism, and a finishing panel is provided on the side of the finishing assembly facing the mold. When the mold containing concrete is transferred to the outlet end, the finishing assembly is activated. The finishing panel moves towards the mold and inserts into the inner wall of the mold. Due to the insertion of the finishing panel, a certain gap is created between the concrete and the inner wall of the mold, thereby achieving separation of the concrete from the inner wall of the mold. This operation helps the test block to be smoothly removed from the mold during subsequent demolding, avoiding damage to the test block due to the concrete sticking to the inner wall of the mold.

[0016] The demolding mechanism is installed on one side of the outlet end of the transfer mechanism. After the finishing component completes the finishing operation, the outlet end of the transfer mechanism sends the mold containing concrete into the demolding mechanism. The demolding mechanism starts and sends out the mold containing concrete. Workers can collect the mold that has completed the placement and finishing operations at the output end of the demolding mechanism, waiting for subsequent curing and demolding processes.

[0017] Through the collaborative work of the above-mentioned institutions, the molding machine has achieved fully automated operation of the entire process of raw material feeding, mixing, mold placement, transfer, surface finishing, and demolding in the concrete test block production process, thereby improving production efficiency and test block quality.

[0018] Preferably, the finishing assembly further includes a finishing cylinder, a connecting plate, and a plurality of finishing panels;

[0019] The cylinder body of the trimming cylinder is connected to the upper part of the outlet end, and the drive end of the trimming cylinder faces the mold. The drive end of the trimming cylinder is connected to one side of the connecting plate, and the plurality of trimming panels are connected to the other side of the connecting plate.

[0020] Preferably, the trimming panel is provided with four panels, which form a rectangle, and the rectangle formed by the four trimming panels corresponds to the inner wall of the mold.

[0021] Preferably, every four of the repair panels constitute a repair group, and multiple repair groups are provided, with the multiple repair groups connected to each other through the connecting plate.

[0022] Preferably, the flipping assembly includes a flipping frame, a flipping cylinder, and a rotating shaft. The two ends of the rotating shaft are connected to the two sides of the flipping frame, and the hopper body is rotatably connected to the rotating shaft. The drive end of the flipping cylinder is connected to the bottom surface of the hopper body, and the cylinder body of the flipping cylinder is connected to the flipping frame.

[0023] Preferably, the transfer mechanism includes a transfer frame, a lateral movement component, and a longitudinal movement component. The lateral movement component is installed inside the transfer frame, and its two ends are located at the inlet end and the outlet end, respectively.

[0024] The lateral movement assembly includes a tray, rollers, guide rails, and a lateral cylinder. The rollers are mounted on both sides of the tray, and the guide rails are mounted on both sides of the transfer frame, with both ends of the guide rails extending to the inlet and outlet ends. The rollers on both sides are mounted in the guide rails on both sides. The lateral cylinder is parallel to the guide rails, and the drive end of the lateral cylinder is connected to the tray. The cylinder body of the lateral cylinder is connected to the transfer frame.

[0025] Preferably, the transfer mechanism further includes a longitudinal movement component, which is installed at the outlet end and connected to the transfer frame;

[0026] The longitudinal moving assembly includes a push plate and a longitudinal cylinder. The longitudinal cylinder is connected to the transfer frame, and the drive end of the longitudinal cylinder faces one side of the demolding mechanism. The push plate is installed on the drive end of the longitudinal cylinder.

[0027] Preferably, the stirring mechanism includes a housing, a stirring motor, a stirring shaft, and a stirring rod;

[0028] The housing is installed on one side of the tilting hopper mechanism, and a discharge port is provided on the top of the housing and a discharge port is provided on the bottom of the housing. The discharge port is opposite to the inlet end. The stirring shaft passes through the housing and is rotatably connected to the housing.

[0031] Preferably, the ejection mechanism includes an ejection conveyor belt, which is opposite to the exit end.

[0032] Compared with the prior art, the beneficial effects of this utility model are:

[0033] This invention integrates a tilting hopper mechanism, a mixing mechanism, a transfer mechanism, a mold-feeding mechanism, and a mold-discharging mechanism. These mechanisms work in close coordination to achieve fully automated operation from concrete raw material input to mold delivery. Compared to traditional manual operation, this avoids delays caused by human intervention between different processes and operational errors, significantly shortening the production cycle time for each test block and substantially improving production efficiency.

[0034] Simultaneously, a finishing component installed at the outlet end inserts a finishing panel into the inner wall of the mold, separating the concrete from the mold's inner wall. This operation effectively prevents the test block from being damaged due to adhesion to the mold during removal, ensuring the integrity of the test block. Intact test blocks can more accurately reflect the performance of the concrete, providing reliable data support for subsequent tests and inspections. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0047] Example 1

[0048] This embodiment discloses a molding machine, such as Figures 1-8 As shown, it includes a tilting hopper mechanism 1, a stirring mechanism 2, a transfer mechanism 3, a mold feeding mechanism 4, and a mold ejection mechanism 5.

[0049] The tilting hopper mechanism 1 consists of a hopper body 10 and a tilting component 11. The hopper body 10 is mounted on the tilting component 11, and the mixing mechanism 2 is installed on one side of the tilting hopper mechanism 1. Workers pour concrete raw materials into the hopper body 10. When it is necessary to supply material to the mixing mechanism 2, the tilting component 11 starts operating, causing the hopper body 10 to tilt. Since the mixing mechanism 2 is located on one side of the tilting hopper mechanism 1, as the hopper body 10 tilts, the concrete inside is poured in from above the mixing mechanism 2, providing raw materials for subsequent mixing operations.

[0050] The mixing mechanism 2 is installed on one side of the tilting hopper mechanism 1, with a discharge port at its bottom, which is opposite to the inlet end 30 of the transfer mechanism 3. Concrete poured from the tilting hopper mechanism 1 enters the mixing mechanism 2. The mixing mechanism 2 starts, thoroughly mixing the concrete to ensure its components are evenly combined. After mixing, the concrete flows out from the discharge port at the bottom of the mixing mechanism 2 and falls directly into the prepared mold in the transfer mechanism 3, which is located below and opposite to the inlet end 30.

[0051] The mold feeding mechanism 4 is installed on one side of the inlet end 30 of the transfer mechanism 3. The worker places the mold to be filled with concrete on the mold feeding mechanism 4. The mold feeding mechanism 4 is activated, sending the mold into the inlet end 30 of the transfer mechanism 3, so that the mold is in the position to receive the mixed concrete.

[0052] The transfer mechanism 3 is installed below the mixing mechanism 2 and has an inlet end 30 and an outlet end 31. After the mixing mechanism 2 pours the mixed concrete into the mold located at the inlet end 30, the transfer mechanism 3 begins to work. It smoothly transfers the mold containing the concrete from the inlet end 30 to the outlet end 31. This transfer process ensures that the mold will not shake or tilt during the transfer, guaranteeing that the concrete is evenly distributed within the mold.

[0053] A finishing assembly 35 is located at the outlet end 31 of the transfer mechanism 3, and a finishing panel 350 is provided on the side of the finishing assembly 35 facing the mold. When the mold containing concrete is transferred to the outlet end 31, the finishing assembly 35 is activated. The finishing panel 350 moves towards the mold and inserts into the inner wall of the mold. Due to the insertion of the finishing panel 350, a certain gap is created between the concrete and the inner wall of the mold, thereby achieving separation of the concrete from the inner wall of the mold. This operation helps the test block to be smoothly removed from the mold during subsequent demolding, avoiding damage to the test block due to the concrete adhering to the inner wall of the mold.

[0054] The demolding mechanism 5 is installed on one side of the outlet end 31 of the transfer mechanism 3. After the finishing component 35 completes the finishing operation, the outlet end 31 of the transfer mechanism 3 sends the mold containing concrete into the demolding mechanism 5. The demolding mechanism 5 starts and sends out the mold containing concrete. The workers can collect the mold that has completed the placement and finishing operations at the output end of the demolding mechanism 5, waiting for subsequent curing and demolding processes.

[0055] Through the collaborative work of the above-mentioned institutions, the molding machine has achieved fully automated operation of the entire process of raw material feeding, mixing, mold placement, transfer, surface finishing, and demolding in the concrete test block production process, thereby improving production efficiency and test block quality.

[0056] In some optional embodiments, when the finishing component 35 is working, the cylinder body of the finishing cylinder 351 is connected to the top of the outlet end 31, the drive end faces the mold and is connected to one side of the connecting plate 352, and multiple finishing panels 350 are connected to the other side of the connecting plate 352. When the mold reaches the designated position at the outlet end 31, the finishing cylinder 351 is activated, the drive end extends, and pushes the connecting plate 352 to move the multiple finishing panels 350 toward the mold. The finishing panels 350 are inserted into the inner wall of the mold, realizing the separation of concrete from the inner wall of the mold.

[0057] In some optional embodiments, four trimming panels 350 form a rectangle corresponding to the inner wall of the mold. When the trimming cylinder 351 pushes the connecting plate 352, the four trimming panels 350 are simultaneously inserted into the inner wall of the mold, separating the concrete from the inner wall of the mold from four directions, ensuring uniform separation of the concrete from the inner wall of the mold, and avoiding damage to the test block due to local adhesion when it is removed.

[0058] In some optional embodiments, every four finishing panels 350 constitute a finishing group, and multiple finishing groups are interconnected by connecting plates 352. When the finishing cylinder 351 pushes the connecting plate 352, multiple finishing groups act simultaneously, which more effectively separates the concrete from the inner wall of the mold for multi-compartment molds, improving the finishing effect.

[0059] In some optional embodiments, when the tilting assembly 11 is in operation, both ends of the rotating shaft 112 are connected to the sides of the tilting frame 110, and the hopper body 10 is rotatably connected to the rotating shaft 112. The cylinder body of the tilting cylinder 111 is connected to the tilting frame 110, and the drive end is connected to the bottom surface of the hopper body 10. When it is necessary to feed material to the mixing mechanism 2, the tilting cylinder 111 is activated, the drive end retracts or extends, driving the hopper body 10 to tilt around the rotating shaft 112, so that the concrete in the hopper body 10 is poured into the mixing mechanism 2 from above.

[0060] In some optional embodiments, when the lateral movement assembly 33 is in operation, rollers 331 are mounted on both sides of the pallet 330, and guide rails 332 are mounted on both sides of the transfer frame 32, extending to the inlet end 30 and the outlet end 31. The rollers 331 are mounted in the guide rails 332. The lateral cylinder 333 is parallel to the guide rails 332, with the cylinder body connected to the transfer frame 32 and the drive end connected to the pallet 330. When the mold enters the inlet end 30, the lateral cylinder 333 is activated, and the drive end extends or retracts, causing the pallet 330 to move on the guide rails 332 via the rollers 331, smoothly transferring the concrete-filled mold from the inlet end 30 to the outlet end 31.

[0061] In some alternative embodiments, the longitudinal moving assembly 34 is mounted on the outlet end 31 and connected to the transfer frame 32. When the mold containing concrete reaches the outlet end 31, the longitudinal cylinder 341 is activated, and its driving end extends toward the mold ejection mechanism 5, driving the push plate 340 to move. The push plate 340 pushes the mold from the outlet end 31 into the mold ejection mechanism 5, realizing the transfer of the mold between the transfer mechanism 3 and the mold ejection mechanism 5.

[0062] In some optional embodiments, when the mixing mechanism 2 is working, the housing 20 is installed on one side of the tilting hopper mechanism 1, with a discharge port at the top and a discharge port at the bottom, opposite to the inlet end 30 of the transfer mechanism 3. The mixing shaft 22 passes through the housing 20 and is rotatably connected to the housing 20, with one end extending outside the housing 20 and connected to the drive end of the mixing motor 21. Multiple sets of mixing rods 23 are staggered on the mixing shaft 22, and each set of mixing rods 23 has a mixing block at its end. After the concrete enters the housing 20 from the discharge port, the mixing motor 21 starts, driving the mixing shaft 22 to rotate. The mixing rods 23 and the mixing block rotate accordingly, thoroughly mixing the concrete. After mixing is complete, the concrete flows out from the discharge port.

[0063] In some optional embodiments, when the mold feeding mechanism 4 is working, the mold feeding conveyor belt 40 is opposite to the inlet end 30 of the transfer mechanism 3. The push cylinder 42 is set on both sides of the mold feeding conveyor belt 40, with the drive end facing the inlet end 30 and equipped with a push block 41. When the operator places the mold on the mold feeding conveyor belt 40, and the mold moves with the conveyor belt to a position close to the inlet end 30, the push cylinder 42 is activated, the drive end extends, and drives the push block 41 to push the mold into the inlet end 30 of the transfer mechanism 3.

[0064] In some alternative embodiments, when the demolding mechanism 5 is in operation, the demolding conveyor belt 50 is opposite to the outlet end 31 of the transfer mechanism 3. After the mold containing concrete is pushed into the demolding mechanism 5 by the longitudinal moving component 34 of the transfer mechanism 3, the mold falls onto the demolding conveyor belt 50, the demolding conveyor belt 50 starts, and sends the mold out. Workers can collect the mold at the output end of the demolding conveyor belt 50.

[0065] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
