Description

Technical Field

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

[0002] At present, in the autoclaved aerated concrete board production industry, most boards need to be turned 90 degrees before packaging, loading or storage. Before turning the boards, they often need to be pre-packed in layers, that is, according to the set number of boards, the stacked boards are layered and pads are placed between the boards in different layers. After the boards in different layers are bundled and packed, the boards are turned over and transported to the next process for storage.

[0003] However, since there are pads after the slabs are layered and there are certain gaps between different layers of slabs, the existing turning machines are unable to remove the pads and gaps between the two layers of slabs, resulting in the turning machine being able to turn over only a single layer of slabs after layering and bundling at one time, and then transporting the turned slabs away for storage together. This turning method has been unable to meet the needs of large-scale concrete slab production, and has seriously affected production efficiency.

[0004] The Chinese patent application number is: CN202010734214.7, and the patent document with the publication date of 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 on the end away from the L-shaped turning table. 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 concrete slab turning table has the problem mentioned above that it can only turn over a single layer of bundled concrete slabs at a time, and there is no effective solution for the pads and gaps between the multi-layer bundled slabs, resulting in low overall slab production efficiency.

[0006] The Chinese patent application number is: CN202111430421.4, and the patent document with the publication date of January 14, 2022 discloses an aerated concrete slab flipping device and its use method. As a device, it includes: a flipping assembly, a removal assembly, and a conveying assembly. The flipping assembly includes multiple flipping frames, and the flipping frame includes a pallet and a linear sliding mechanism perpendicular to the pallet; the removal assembly includes multiple storage mechanisms corresponding to the sliding mechanisms one by one; the conveying assembly includes a transmission mechanism and a translation mechanism; as a method, the flipped aerated concrete slab is moved out of the flipping frame by the sliding trolley on the flipping frame, and parked on the sliding trolley that has entered the storage slide rail, waiting to be close to the next flipped aerated concrete slab parked on the removal slide rail, and then transported by a forklift.

[0007] Compared with conventional turning machines, this concrete slab turning device temporarily takes over the turned slab through the setting of the sliding trolley, so that the two turned slabs can be put together, but it needs to set up various additional devices outside the turning table, which increases the process cost. At the same time, the turning frame still needs to be turned twice, and the improvement of the production efficiency of the slab is still limited. Summary of the invention

Therefore, the scope of the present invention is limited only by the appended claims.

[0033] Example 1

[0034] A double-layer plate turning machine is used in the production of concrete plates to turn over the bundled plates and send them to the next process. Its specific structure and working principle are described in detail below.

[0035] like Figure 1 and Figure 2 As shown, the plate turning machine mainly includes a turning frame 3, a pulley 4, two groups of support blocks 5, a cushion block conveying device 6 and a pulley push-pull device 9.

[0036] The turning frame 3 is provided with fork teeth perpendicular to the turning frame 3, and the turning frame 3 is provided with a slide rail. The bottom of the pulley 4 is matched and mounted on the slide rail through a slider, and is driven to move by the pulley push-pull device 9. One group of support blocks 5 is fixedly mounted on the turning frame 3, and the other group of support blocks 5 is fixedly mounted on the pulley 4. The cushion block conveying device 6 is installed on the turning frame 3 between the two groups of support blocks 5.

[0037] In this embodiment, the two groups of support blocks 5 each have a plurality of support blocks 5, which are arranged at intervals along the turning frame 3 and the pulley 4. The pulley push-pull device 9 is a cylinder, one end of which is connected to the turning frame 3 and the other end is connected to the pulley 4. The pad conveying device 6 is a belt conveyor.

[0038] It is worth mentioning that a stopper is installed at the end of the slide rail, which can limit the maximum moving distance of the pulley 4 when the pulley 4 moves, so as to prevent the pulley 4 from falling off the turning frame 2 and causing the plate to fall.

[0039] In addition, the plate turning machine also includes a track 1, a car body 2 and a car body push-pull device 7. The track 1 is installed on the ground, and the bottom of the car body 2 is matched and installed on the track 1 through a slider, and is driven to move by the car body push-pull device 7. A bearing seat is installed on the car body 2, and a rotating shaft connected to the bearing seat is installed on the turning frame 3, which is driven to rotate by the turning device. In this embodiment, the car body push-pull device 7 is an oil cylinder, one end of which is connected to the ground and the other end is connected to the car body 2. The turning device is also an oil cylinder, one end of which is connected to the turning frame 3 and the other end is connected to the car body 2.

[0040] By installing the turning frame 3 on the movable vehicle body 2, the plate can be close to the conveying vehicle 10, so that the plate on the conveying vehicle 10 can fit with the support block 5, ensuring that the turning process of the plate is more stable and preventing the plate from falling off.

[0041] When working, Figure 3 As shown, the conveyor 10 transports the bundled upper plate 11 and lower plate 12 to one side of the turning machine, and a cushion block 13 is placed between the upper plate 11 and the lower plate 12, so that the conveyor 10 can be raised and lowered. At this time, the fork of the plate turning machine is in a horizontal state, the support block 5 and the cushion block conveying device 6 are in a vertical state, the vehicle body push-pull cylinder is retracted and the vehicle body is in an outer state, the pulley 4 is in the middle position, and the gap between a group of support blocks 5 on the pulley 4 and a group of support blocks 5 on the turning frame 3 is the height of the corresponding cushion block 13.

[0042] When turning over, after the transport vehicle 10 is in place, Figure 4 The turning machine body push-pull cylinder pushes the body 2 to move to one side of the conveying vehicle 10, so that the fork teeth enter the gap between the conveying vehicle 10 and the lower plate 12, and the support block 5 fits with the side of the plate. Figure 4 In this embodiment, the transport vehicle 10 is provided with a plurality of supporting parts for supporting the plate, and the gaps between the fork teeth corresponding to the supporting parts are also multiple and arranged at intervals, and there are gaps between different supporting parts for the fork teeth to extend into.

[0043] Next, the transport vehicle 10 is lowered, so that the plate falls onto the fork teeth and is freed from the support of the transport vehicle. Figure 4Then the flip machine flips 90 degrees clockwise. Figure 4 After the flipping is completed, the conveyor 10 moves back to wait for the next template material to be conveyed. At the same time, the pulley 4 drives the upper plate 11 to move a little distance outward, so that the pad 13 clamped by the upper plate 11 and the lower plate 12 falls onto the belt conveyor below. Figure 4 As shown in e.

[0044] After the cushion block 13 falls onto the belt conveyor, the belt conveyor transports the cushion block 13 to the outside of the turning machine for processing in the next step. At the same time, the pulley 4 drives the upper plate 11 to move inward so that the upper plate 11 and the lower plate 12 are close to each other, and the turning machine body push-pull cylinder pushes the body 2 to move outward. Figure 4 As shown in f.

[0045] Wait for the forklift to transport the flipped plate to the yard or other location. After the forklift takes the plate away, the flipping machine rotates counterclockwise, and the pulley 4 moves outward to increase the distance between the two sets of support blocks 5. Figure 4 As shown in g in FIG. After waiting for the conveying vehicle 10 to convey the plate back again, the next cycle is completed.

[0046] In summary, compared with conventional turning machines, the double-layer plate turning machine of this embodiment can turn over two layers of bundled plates at one time, remove the pads and gaps between the two layers of plates, and effectively improve the production efficiency of the plates.
