Description

Technical Field

[0001] This invention belongs to the field of concrete product production equipment, and more specifically, relates to a double-opening concrete billet turning machine and its turning method. Background Technology

[0002] Currently, in the autoclaved aerated concrete (AAC) product manufacturing industry, block and slab blanks generally need to be rotated 90° to remove the bottom layer before being fed into the next process. However, existing semi-finished product turning machines typically employ an integrated structure with the turning body arranged at a 90-degree angle. When these machines are operating, they often require waiting for the loading and unloading of materials on one side to be completed before they can begin work on the other side. This prevents the two sides from operating synchronously, resulting in low overall efficiency and failing to meet the demands of increased production speed and efficiency in high-capacity AAC block and slab production lines.

[0003] For example, Chinese patent application number CN201310730686.5, published on April 2, 2014, discloses a turning platform for automatically removing waste from aerated concrete (AAC) brick blanks. It includes a horizontal turning frame and a vertical turning frame that are perpendicular to each other, both hinged to the same turning shaft. A power unit for the turning platform is connected to the platform to drive its rotation. The key feature is that it also includes a separation mechanism and a waste collection device for separating and removing waste from both sides of the AAC casting after edge trimming. The separation mechanism includes a separation component and a separation power unit. The separation power unit drives the separation component to run along the trimming marks, either entirely or partially, until the trimmed waste falls off and is separated. The waste collection device for receiving the fallen waste is located below the AAC casting containing the waste to be separated.

[0004] For example, Chinese patent application number CN202010734214.7, published on October 30, 2020, discloses a non-powered aerated concrete panel turning platform, including a base and an L-shaped turning platform. Support blocks are rotatably installed at the middle position on both sides of the L-shaped turning platform, and the two support blocks are fixedly connected to the two sides of the base respectively. Hydraulic cylinders are hinged to the sides of the L-shaped turning platform near the support blocks, and hinge seats are hinged to the ends of the two hydraulic cylinders away from the L-shaped turning platform. The two hinge seats are fixed to the outer wall of the top of the base by bolts. A bracket is fixed to the outer wall of the L-shaped turning platform near the base, and a counterweight component is provided on the side wall of the bracket. A buffer component is provided on the top of the base near the bracket positions of the two support blocks.

[0005] The flipping machines in the two schemes mentioned above use a 90-degree integrated structure for the flipping body. This results in a problem where the flipping machine can only start working on the other side after the loading and unloading work on one side is completed. The work on both sides of the flipping machine cannot be carried out synchronously, leading to low work efficiency. Summary of the Invention

[0006] 1. The problem to be solved

[0014] The locking device connects the first flipping component and the second flipping component when they intersect at 90°.

[0015] As a further improvement to the technical solution, the first tilting assembly includes a first tilting frame, a first trolley, and a first push-pull cylinder;

[0016] The first tilting frame is hinged to the support and is provided with a first slide rail parallel to the tilting direction; the bottom of the first trolley is provided with a first slider that matches the first slide rail, and is equipped with a roller and a base plate drive assembly; the first push-pull cylinder is installed on the first tilting frame to control the movement of the first trolley on the first slide rail.

[0020] As a further improvement to the technical solution, the second trolley is equipped with a second base plate clamping assembly.

[0021] As a further improvement to the technical solution, a pair of bottom skin clamping mechanisms are symmetrically installed on both sides of the second trolley. The bottom skin clamping mechanism includes a pusher and a clamping plate installed at the end of the pusher.

[0022] As a further improvement to the technical solution, the locking device includes a locking shaft, a locking block, a rotating shaft, and a rotating shaft drive mechanism;

[0023] The rotating shaft is rotatably mounted on the upper side of the first flipping assembly, and the rotating shaft drive mechanism is fixedly mounted on the first flipping assembly and controls the rotation of the rotating shaft;

[0024] The locking shaft is located on the side of the second flip assembly away from the first flip assembly; the locking block is fixedly installed on the end of the rotating shaft facing the second flip assembly, and is an annular part with a notch that matches the locking shaft.

[0025] As a further improvement to the technical solution, the rotary shaft drive mechanism includes a mounting base, a locking telescopic component, and a connecting rod;

[0026] The mounting base is fixedly mounted on the first flipping assembly, the locking telescopic component is fixedly mounted on the mounting base, and the two ends of the connecting rod are respectively hinged to the rotating shaft and the telescopic rod of the locking telescopic component.

[0027] A method for turning over concrete billets, using the aforementioned double-opening concrete billet turning machine, includes the following steps:

[0028] 1. In the initial state, both the first flipping assembly and the second flipping assembly are in a horizontal state. The base plate is transported to the first flipping assembly and the second flipping assembly and fixed. The base plate on the second flipping assembly is loaded with the blank.

[0029] 2. Flip the first flipping component 90°, and then connect the first flipping component and the second flipping component with the locking device;

[0030] Third, the first and second flipping components are flipped 90° simultaneously to achieve a 90° flip of the billet and its transfer to the first flipping component. Then, the locking device is activated to separate the first and second flipping components and flip the second flipping component 90° back to its initial state.

[0031] 4. Remove the base plate containing the billet from the first flipping assembly and receive the next base plate. At the same time, move the base plate on the second flipping assembly and receive the next base plate containing the billet.

[0032] 5. Repeat steps one through four.

[0033] As a further improvement to the technical solution, the specific working process of the locking device is as follows:

[0034] In step one, the notch of the locking block in the initial state is horizontally oriented towards the second flipping component;

[0035] In step two, after the first flipping component flips 90°, the rotating shaft is controlled to rotate clockwise by 120° to 135°.

[0036] In step three, the rotating shaft is controlled to rotate so that the locking block returns to its initial state.

[0037] 3. Beneficial effects

[0038] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0039] (1) The present invention provides a double-opening concrete billet turning machine, which controls the turning frames on both sides of the turning machine to turn through separate drive mechanisms, so that the two can work at the same time. This solves the problem that when the existing turning machine is working, it is necessary to wait for the loading and unloading work on one side to be completed before the work on the other side can be carried out, and the work on both sides of the turning machine cannot be carried out synchronously, resulting in low work efficiency.

[0040] (2) The present invention provides a double-opening concrete billet turning machine. By setting a locking device with a unique structure, the two turning frames can be fixed together when they are perpendicular to each other, thereby ensuring the synchronous turning of the two turning frames in subsequent work and completing the turning and transfer of the billet. In particular, the locking device, by setting a simple and ingenious locking shaft and locking block, makes the locking process convenient and quick, without too many complicated operations and complex structures, low cost, and not easy to damage. Moreover, it realizes the vertical positioning of the two turning frames at the same time during locking, which effectively improves the working efficiency and working accuracy of the turning machine.

[0041] (3) The present invention provides a double-opening concrete billet turning machine. By setting a bottom plate clamping component on the trolley of the turning component, the bottom plate can be clamped and fixed on the trolley when the turning component turns, so as to prevent the bottom plate from falling off and ensure the stable operation of the turning machine.

[0042] (4) The present invention provides a double-opening concrete billet turning machine, wherein a slide rail parallel to the turning direction is provided at the bottom of the trolley of the turning component, so that the trolley can adjust the water level position of the turning direction on the turning frame, which facilitates the transportation of the bottom plate and the turning of the billet.

[0043] (5) The present invention provides a double-opening concrete billet turning machine, wherein a pair of bottom skin clamping mechanisms are symmetrically installed on both sides of the second trolley, which can clamp the bottom skin of the billet when the second turning component turns over to transfer the billet to the first turning component, thereby improving the bottom skin separation effect of the billet.

[0054] Exemplary embodiments of the present invention are described in detail below. While these exemplary embodiments have been described in sufficient detail to enable those skilled in the art to practice the invention, it should be understood that other embodiments may be implemented and various changes may be made to the invention without departing from its spirit and scope. The more detailed description of embodiments of the invention below is not intended to limit the scope of the claimed invention, but is merely illustrative and does not limit the description of the features and characteristics of the invention, in order to suggest the best mode for carrying out the invention and to enable those skilled in the art to practice it. Therefore, the scope of the invention is defined only by the appended claims.

[0055] Example 1

[0056] A double-opening concrete billet turning machine is used in the autoclaved aerated concrete (AAC) product manufacturing industry. It turns over the billets of blocks and slabs to remove the bottom layer and prepare them for subsequent processes. The specific structure and technical effects are described in detail below.

[0057] like Figure 1 As shown, the flipping machine mainly includes a base 1, a support 2, a first flipping component 3, a first flipping drive component 4, a second flipping component 5, a second flipping drive component 6, and a locking device 7.

[0058] In this embodiment, the base 1 serves as the mounting base for the tilting machine, typically fixedly mounted on the ground or a platform, while the support 2 is fixedly mounted on the base 1. To ensure the overall structural strength of the tilting machine, a set of base 1 and support 2 are respectively installed at both ends of the machine.

[0059] like Figure 2 and Figure 3 As shown, the first tilting assembly 3 includes a first tilting frame 31, a first trolley 32 and a first push-pull cylinder 33.

[0060] The first tilting frame 31 is hinged to a support 2 at both ends, and the first tilting drive 4 is a hydraulic cylinder set on the base 1 to drive the first tilting assembly 3 to rotate along the hinge point.

[0061] The first tilting frame 31 is provided with a first slide rail 34 parallel to the tilting direction, which is perpendicular to the conveying direction of the base plate and is generally the width direction of the tilting frame. The bottom of the first trolley 32 is provided with a first slider 35 that matches the first slide rail 34, on which rollers and a base plate drive assembly are mounted. In this embodiment, multiple rollers are arranged at intervals along the base plate conveying direction on the upper side of the first trolley 32. The base plate drive assembly uses at least one motor connected to the rollers for transmission, driving the rollers to rotate and thus moving the base plate on the rollers through friction. The cylinder seat of the first push-pull cylinder 33 is mounted on the first tilting frame 31, and its piston rod is hinged to the first trolley 32, controlling the movement of the first trolley 32 on the first slide rail 34. Furthermore, the first trolley 32 is also equipped with a first base plate clamping assembly 36, which can clamp the base plate when the first tilting assembly tilts, preventing the base plate from falling off.

[0062] like Figure 4 and Figure 5 As shown, the second tilting assembly 5 includes a second tilting frame 51, a second trolley 52, and a second push-pull cylinder 53.

[0063] The second tilting frame 51 is hinged to the support 2 or the first tilting assembly 3. In this embodiment, the second tilting frame 51 is installed inside the first tilting frame 31, and its two sides are hinged to the two sides of the first tilting frame 31 respectively. The second tilting drive 6 is a hydraulic cylinder mounted on the base 1, which drives the second tilting assembly 5 to rotate along the hinge point.

[0064] Similar to the arrangement of the first tilting frame 31, the second tilting frame 51 is also equipped with a second slide rail 54 parallel to the tilting direction. The bottom of the second trolley 52 is equipped with a second slider 55 that matches the second slide rail 54. The second trolley 52 is equipped with rollers and a base plate drive assembly. In this embodiment, although the second trolley 52 is also equipped with multiple rollers along the base plate conveying direction, these rollers are unpowered and only serve a supporting function. The base plate drive assembly consists of friction wheels installed between the rollers and a motor connected to the friction wheels. The motor controls the rotation of the friction wheels to move the base plate. The cylinder seat of the second push-pull cylinder 53 is installed on the second tilting frame 51, and its piston rod is hinged to the second trolley 52, controlling the movement of the second trolley 52 on the second slide rail 54. Furthermore, the second trolley 52 is also equipped with a second base plate clamping assembly 56, which has a structure and function basically the same as the first base plate clamping assembly 56.

[0065] It is worth mentioning that the second flipping component 5 is a component that receives the bottom plate containing the billet and flips and transfers the billet to the first flipping component 3, achieving separation of the bottom skin of the billet during the billet flipping process. To meet this requirement, this embodiment symmetrically installs a pair of bottom skin clamping mechanisms 57 on both sides of the second trolley 52. ​​The bottom skin clamping mechanism 57 includes a pusher and a clamping plate installed at the end of the pusher. The pusher can be any one of a cylinder, a hydraulic cylinder, or an electric push rod, so that when flipping the billet, it can clamp the bottom skin of the billet, so that the bottom skin stays on the second flipping component 5, while the billet is transferred to the first flipping component 3. In this way, the bottom skin removal effect is improved.

[0066] In this embodiment, the first base plate clamping assembly 36 and the second base plate clamping assembly 56 are prior art in the field, so they will not be described in detail. For details, please refer to the patent document with patent application number CN202110707223.1 entitled: A mechanism for conveniently fixing and clamping the base plate of an aerated concrete turning table.

[0067] like Figure 7 and Figure 8 As shown, the locking device 7 includes a locking shaft 71, a locking block 72, a rotating shaft 73, and a rotating shaft drive mechanism.

[0068] The rotating shaft 73 is rotatably mounted on the upper side of the first tilting assembly 3, and the rotating shaft drive mechanism is fixedly mounted on the first tilting assembly 3 and controls the rotation of the rotating shaft 73. The rotating shaft drive mechanism includes a mounting base 74, a locking telescopic member 75, and a connecting rod 76. The mounting base 74 is fixedly disposed on the first tilting assembly 3, the locking telescopic member 75 is fixedly mounted on the mounting base 74, and the two ends of the connecting rod 76 are respectively hinged to the telescopic rods of the rotating shaft 73 and the locking telescopic member 75. In this embodiment, the locking telescopic member 75 is any one of a hydraulic cylinder, a pneumatic cylinder, or an electric push rod. The extension and retraction of the telescopic rod causes the connecting rod 76 to drive the rotating shaft 73 to rotate.

[0069] A locking shaft 71 is disposed on the side of the second flip assembly 5 away from the first flip assembly 3. A locking block 72, which is a ring-shaped component, is fixedly installed on the end of the rotating shaft 73 facing the second flip assembly 3 and has a notch that matches the locking shaft 71. After the locking shaft 71 is engaged in the notch of the locking block 72, the two are locked together by rotating the rotating shaft 73, thereby connecting the first flip assembly 3 and the second flip assembly 5.

[0070] To better understand the working principle and technical effects of the flipping machine in this embodiment, the following flipping method of the flipping machine is described, specifically including the following steps:

[0071] 1. In the initial state, both the first flipping component 3 and the second flipping component 5 are in a horizontal state. At this time, as follows: Figure 9As shown in state a, the notch of the locking block 72 is horizontally oriented toward the second flipping assembly 6, and then the base plate is transported to the first flipping assembly 3 and the second flipping assembly 5 and fixed. The base plate on the second flipping assembly 5 is equipped with the blank.

[0072] 2. Rotate the first flipping component 3 90°. At this time, the locking block 72 engages with the locking shaft 71, as follows: Figure 9 As shown in state b, then control the rotating shaft 73 to rotate clockwise by 120° to 135°, so that the locking block 72 and the locking shaft 71 are in the same state. Figure 9 As shown in state c. In this state, when the first flipping component 3 and the second flipping component 5 are flipped, the locking shaft 71 and the locking block 72 will block each other in the flipping direction, thereby ensuring the synchronous flipping effect of the first flipping component 3 and the second flipping component 5, and realizing the locking and fixing between the first flipping component 3 and the second flipping component 5.

[0073] Third, simultaneously rotate the first flipping assembly 3 and the second flipping assembly 5 by 90°, so that the locking block 72 and the locking shaft 71 are in the following states: Figure 9 As shown in state d, the billet is flipped 90° and transferred to the first flipping assembly 3. Then, as... Figure 9 As shown in state e, the locking block 72 is rotated to its initial horizontal position facing the second flipping component 5, causing the first flipping component 3 and the second flipping component 5 to separate. Finally, the second flipping component 5 is flipped 90° to return to its initial state.

[0074] Fourth, remove the base plate containing the blank from the first flipping assembly 3 and receive the next base plate. Simultaneously, move the base plate on the second flipping assembly 3 to receive the next base plate containing the blank, i.e. Figure 6 The machine, as shown, performs simultaneous loading and unloading operations on both sides.

[0075] 5. Repeat steps one through four.

[0076] It must be noted that in this embodiment, the structural arrangement for separately controlling the two flipping components is not difficult. The difficulty lies in how to ensure the synchronous rotation of the first flipping component 3 and the second flipping component 5 when flipping the blank, and how to ensure the locking device 7 can guarantee the locking accuracy and strength while keeping the structure and operation as simple as possible, reducing costs and locking time, and ensuring flipping efficiency.

[0077] In this embodiment, the locking device 7 only requires setting the installation positions of the locking shaft 71 and the locking block 72 so that when the first flipping component 3 is exactly perpendicular to the second flipping component 5, the locking shaft 71 can engage with the locking block 72, thus quickly achieving the locking and positioning of the first flipping component 3 and the second flipping component 5. At this time, simply rotating the locking block 72 is sufficient to quickly complete the locking process. The entire locking process is not only convenient and quick, effectively improving the working efficiency of the flipping machine, but also has a simple structure, is not easily damaged, has low manufacturing cost, and good stability. At the same time, it can simultaneously achieve locking and positioning, resulting in excellent application effects.

[0078] In summary, the double-opening concrete billet turning machine of this embodiment controls the turning frames on both sides of the turning machine to turn through separate drive mechanisms, so that the two can work simultaneously. This solves the problem that existing turning machines require waiting for the loading and unloading of one side to be completed before the work on the other side can begin, resulting in the inability to synchronize the work on both sides and low work efficiency.

[0079] The examples described herein are merely preferred embodiments of the invention and are not intended to limit the concept and scope of the invention. Any modifications and improvements made by those skilled in the art to the technical solutions of the invention without departing from the design concept of the invention should fall within the protection scope of the invention.
