Description

Technical Field

[0001] The utility model belongs to the field of concrete product production equipment, and more specifically relates to a double-opening concrete blank turning machine. Background Art

[0002] At present, in the autoclaved aerated concrete product production industry, most of the blocks and panels need to be flipped 90 degrees to remove the bottom skin, and then the flipped panels are sent to the next process to continue production. However, the existing semi-finished product flipping machines generally adopt an overall structure with a flipping body arranged at 90 degrees. When the flipping machine is working, it often needs 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. The work on both sides of the flipping machine cannot be carried out synchronously, resulting in the overall work efficiency of the flipping machine is not high, and it cannot meet the current large-capacity aerated concrete block and panel production line speed increase and improve production efficiency.

[0003] For example, the Chinese patent application number is CN201310730686.5, and the publication date is April 2, 2014, which discloses a turning table of an aerated concrete equipment for automatically removing waste bricks. It includes a horizontal turning frame and a vertical turning frame perpendicular to each other, and both turning frames are hinged to the same turning axis. The turning table power device is connected to the turning table by driving the turning table to turn. The key point of its composition is that it also includes a separation mechanism and a waste collection device for separating and removing waste on both sides of the aerated concrete casting body that has completed trimming. The separation mechanism includes a separation component and a separation power device. The separation power device drives the separation component to run along the trimming trace or lag behind the trimming waste for the whole process or a part until the trimming waste falls and is separated. The waste collection device for receiving the fallen separated waste is arranged under the aerated concrete casting body of the waste to be separated.

[0004] For example, the patent document with Chinese patent application number: CN202010734214.7 and publication date: October 30, 2020, discloses a non-powered aerated concrete slab turning table, including a base and an L-shaped turning table, wherein support blocks are rotatably arranged at the middle position of one side of both sides of the L-shaped turning table, and the two support blocks are respectively fixedly connected to the two sides of the base, and oil cylinders are hinged on both sides of the L-shaped turning table close to the support blocks, and the two oil cylinders are hinged with hinged seats at the end away from the L-shaped turning table, and the two hinged seats are fixed to the outer wall of the top of the base by bolts, and a bracket is fixed on one side of the outer wall of one side of the L-shaped turning table close to the base, and a counterweight assembly is arranged on the side wall of the bracket, and a buffer assembly is arranged at the top of the base close to the position of the two support block brackets.

[0005] The flipping machine in the above two solutions adopts a flipping body with an overall structure arranged at 90 degrees. When the flipping 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. The work on both sides of the flipping machine cannot be carried out synchronously, resulting in low work efficiency. Utility Model Content

The more detailed description of the embodiments of the present invention below is not intended to limit the scope of the claimed present invention, but is merely for illustration and does not limit the description of the features and characteristics of the present invention, in order to propose the best way to perform the present invention, and is sufficient to enable those skilled in the art to implement the present invention. Therefore, the scope of the present invention is limited only by the appended claims.

[0045] Example 1

[0046] A double-opening concrete body turning machine is used in the autoclaved aerated concrete product production industry to turn over blocks and plate bodies to remove the bottom skin and prepare for subsequent other processes. Its specific structure and technical effects are described in detail below.

[0047] like Figure 1 As shown, the turning machine mainly includes a base 1, a support 2, a first turning assembly 3, a first turning drive member 4, a second turning assembly 5, a second turning drive member 6 and a locking device 7.

[0048] The base 1 is the installation base of the turning machine, which is generally fixed on the ground or a platform, and the support 2 is fixed on the base 1. In this embodiment, in order to ensure the overall structural strength of the turning machine, a set of base 1 and support 2 are respectively provided at both ends of the turning machine.

[0049] like Figure 2 and Figure 3As shown, the first turning assembly 3 includes a first turning frame 31 , a first pulley 32 and a first push-pull cylinder 33 .

[0050] The two ends of the first flip frame 31 are respectively hingedly connected to a support 2, and the first flip driving member 4 adopts a cylinder arranged on the base 1 to drive the first flip assembly 3 to rotate along the hinge point.

[0051] The first turning frame 31 is provided with a first slide rail 34 parallel to the turning direction, and the turning direction is perpendicular to the conveying direction of the bottom plate, generally the width direction of the turning frame. The bottom of the first pulley 32 is provided with a first slider 35 matching the first slide rail 34, on which rollers and bottom plate driving components are installed. In this embodiment, a plurality of rollers are arranged at intervals along the conveying direction of the bottom plate on the upper side of the first pulley 32, and the bottom plate driving component adopts at least one motor connected to the rollers, which drives the rollers to rotate through the motor and then drives the bottom plate on the rollers to move through friction. The cylinder seat of the first push-pull oil cylinder 33 is installed on the first turning frame 31, and its piston rod is hingedly connected to the first pulley 32 to control the first pulley 32 to move on the first slide rail 34. In addition, the first pulley 32 is also equipped with a first bottom plate clamping component 36, which can clamp the bottom plate when the first turning component is turned over to prevent the bottom plate from falling off.

[0052] like Figure 4 and Figure 5 As shown, the second turning assembly 5 includes a second turning frame 51 , a second pulley 52 and a second push-pull cylinder 53 .

[0053] The second flip frame 51 is hingedly connected to the support 2 or the first flip assembly 3. In this embodiment, the second flip frame 51 is installed on the inner side of the first flip frame 31, and its two sides are respectively hingedly connected to the two sides of the first flip frame 31. The second flip driving member 6 uses a cylinder arranged on the base 1 to drive the second flip assembly 5 to rotate along the hinge point.

[0054] The second turning frame 51 is also provided with a second slide rail 54 parallel to the turning direction, and the second slider 55 matching the second slide rail 54 is provided at the bottom of the second pulley 52. ​​The second pulley 52 is equipped with rollers and a bottom plate driving assembly. In this embodiment, although the second pulley 52 is also equipped with multiple rollers along the bottom plate conveying direction, the rollers are unpowered rollers and only play a supporting role. The bottom plate driving 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 drive the bottom plate to move. The cylinder seat of the second push-pull oil cylinder 53 is installed on the second turning frame 51, and its piston rod is hingedly connected to the second pulley 52 to control the second pulley 52 to move on the second slide rail 54. In addition, the second pulley 52 is also equipped with a second bottom plate clamping assembly 56 with a structure and function basically consistent with the first bottom plate clamping assembly 56.

[0055] It is worth mentioning that the second flipping assembly 5 is a component that receives the bottom plate with the blank and flips and transfers the blank to the first flipping assembly 3, so as to separate the bottom skin of the blank during the flipping process. In view of this requirement, the present embodiment symmetrically installs a pair of bottom skin clamping mechanisms 57 on both sides of the second pulley 52. ​​The bottom skin clamping mechanism 57 includes a push member and a clamping plate installed at the end of the push member. The push member can be any one of a cylinder, an oil cylinder and an electric push rod, so that when the blank is flipped, the bottom skin at the bottom of the blank can be clamped, so that the bottom skin stays on the second flipping assembly 5, and the blank is transferred to the first flipping assembly 3, so as to improve the removal effect of the bottom skin in this way.

[0056] In this embodiment, the first bottom plate clamping assembly 36 and the second bottom plate clamping assembly 56 belong to the prior art in this field, so they are not described in detail. For details, please refer to the patent application number: CN202110707223.1, entitled: A patent document for a mechanism for conveniently fixing and clamping the bottom plate of an aerated concrete turning table.

[0057] 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 driving mechanism.

[0058] The rotating shaft 73 is rotatably mounted on the upper side of the first flip assembly 3, and the rotating shaft driving mechanism is fixedly mounted on the first flip assembly 3 and controls the rotation of the rotating shaft 73. The rotating shaft driving mechanism includes a mounting seat 74, a locking telescopic member 75 and a connecting rod 76. The mounting seat 74 is fixedly arranged on the first flip assembly 3, the locking telescopic member 75 is fixedly mounted on the mounting seat 74, and the two ends of the connecting rod 76 are respectively hingedly connected to the rotating shaft 73 and the telescopic rod of the locking telescopic member 75. In this embodiment, the locking telescopic member 75 adopts any one of an oil cylinder, an air cylinder or an electric push rod, and the connecting rod 76 drives the rotating shaft 73 to rotate through the extension and retraction of the telescopic rod.

[0059] The locking shaft 71 is arranged on a side of the second flip assembly 5 away from the first flip assembly 3, and the locking block 72 is fixedly mounted on one end of the rotating shaft 73 facing the second flip assembly 3, and is an annular member having a notch matching the locking shaft 71. After the locking shaft 71 is inserted into the notch of the locking block 72, the rotating shaft 73 is rotated to lock the two, thereby realizing the connection between the first flip assembly 3 and the second flip assembly 5.

[0060] In order to better understand the working principle and technical effect of the flipping machine of this embodiment, the flipping method of the flipping machine is described below, which specifically includes the following steps:

[0061] 1. In the initial state, the first flip assembly 3 and the second flip assembly 5 are both in a horizontal state. Fig. 9 As shown in state a, the notch of the locking block 72 is horizontally facing the second flip assembly 6, and then the bottom plate is transported to the first flip assembly 3 and the second flip assembly 5 and fixed, and the bottom plate on the second flip assembly 5 is equipped with a blank.

[0062] 2. Flip the first flip assembly 3 by 90°. At this time, the locking block 72 is engaged with the locking shaft 71. Fig. 9 Then, the rotating shaft 73 is controlled to rotate 120° to 135° clockwise, so that the state of the locking block 72 and the locking shaft 71 changes to Fig. 9 In this state, when the first flip assembly 3 and the second flip assembly 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 flip assembly 3 and the second flip assembly 5, and realizing the locking and fixing between the first flip assembly 3 and the second flip assembly 5.

[0063] 3. Turn the first flip assembly 3 and the second flip assembly 5 by 90° at the same time, so that the state of the locking block 72 and the locking shaft 71 becomes Fig. 9 As shown in the state d, the blank is turned over 90° and transferred to the first turning assembly 3. Then as Fig. 9 As shown in state e in FIG, the locking block 72 is controlled to rotate to the initial horizontal state toward the second flip assembly 5, so that the first flip assembly 3 and the second flip assembly 5 are separated, and finally the second flip assembly 5 is flipped 90° to return to the initial state.

[0064] Fourth, the bottom plate with the blank on the first flip assembly 3 is removed and the next bottom plate is received. At the same time, the bottom plate on the second flip assembly 3 is moved and the next bottom plate with the blank is received. Figure 6 As shown, loading and unloading work is carried out simultaneously on both sides of the turning machine.

[0065] 5. Repeat steps 1 to 4.

[0066] It must be pointed out that, in the present embodiment, the structural arrangement for separately controlling the flipping assemblies on both sides is not difficult. The difficulty lies in how to ensure the synchronous rotation of the first flipping assembly 3 and the second flipping assembly 5 when flipping the blank, and how to ensure that the locking device 7 can ensure the simplicity of structure and operation as much as possible, reduce costs and locking time, ensure flipping efficiency, and at the same time ensure locking accuracy and strength.

[0067] The locking device 7 of this embodiment only needs to set the installation positions of the locking shaft 71 and the locking block 72 so that when the first flip assembly 3 is exactly perpendicular to the second flip assembly 5, the locking shaft 71 can be inserted into the locking block 72, and the first flip assembly 3 and the second flip assembly 5 can be quickly locked and positioned. At this time, the locking block 72 can be quickly rotated to complete the locking. The entire locking process is not only convenient and fast, effectively improving the working efficiency of the flip machine, but also has a simple structure, is not easy to damage, has a low manufacturing cost, and has good stability. At the same time, it can also achieve locking and positioning synchronously, and the application effect is excellent.

[0068] To sum up, a double-opening concrete blank turning machine in this embodiment controls the turning frames on both sides of the turning machine to turn through a separate driving mechanism, so that the two can work at the same time, which 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 working on the other side, and the work on both sides of the turning machine cannot be carried out synchronously, resulting in low work efficiency.

[0069] The examples described in the present invention are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made to the technical solutions of the present invention by engineers and technicians in this field shall fall within the protection scope of the present invention.
