Description

Technical Field

[0001] This utility model belongs to the field of aerated concrete product manufacturing technology, specifically a continuous ring cutting system for aerated concrete blocks and panels. Background Technology

[0002] With the development of the gas filling industry, the market has experienced explosive growth. To improve competitiveness, gas filling plants are demanding higher and higher annual production capacity, and the cycle time of each process is getting shorter and shorter.

[0003] Currently, the cutting unit uses a cutting conveyor to transport materials back and forth. The cutting conveyor needs to carry the base plate and the slab along the conveying route to complete the cutting and unloading operations. After unloading, the cutting conveyor returns from the unloading position to the loading position (i.e., from the end position to the initial position). Cutting operations cannot be performed during the return process of the cutting conveyor, resulting in low cutting efficiency and long production cycle. This method cannot meet the increasingly high production capacity requirements to a certain extent.

[0004] Therefore, a continuous ring cutting system for aerated concrete block panels is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing aerated concrete block panel cutting system has low cutting efficiency and long production cycle, which cannot meet the requirements of large production capacity.

[0006] To solve the above-mentioned technical problems, the inventors, through practice and summarization, derived the technical solution of this utility model, which adopts the following technical solution:

[0007] A continuous circular cutting system for aerated concrete block panels includes a conveying device, a conveying vehicle on the conveying device for holding the blanks, and the path of the conveying vehicle on the conveying device is a loop.

[0008] The conveying device is equipped with a feeding area, a longitudinal cutting area, a transverse cutting area, and a discharging area;

[0009] A separate loading crane is set up in the loading area to transport the billet to the conveyor vehicle;

[0010] A separate longitudinal cutting machine is set up in the longitudinal cutting zone, which longitudinally cuts the billet passing through it;

[0011] A separate cross-cutting machine is set up in the cross-cutting zone, which cross-cuts the billet passing through it;

[0012] A separate unloading crane is set up in the palletizing area to unload the billets from the conveyor truck.

[0013] The conveyor is equivalent to the carrier or working platform of the billet. Its travel path forms a loop. Multiple sets of conveyor vehicles form an assembly line operation mode in the loop. Each conveyor vehicle works at the corresponding work station at the same time, which effectively improves the efficiency of cutting.

[0014] In this application, the cutting system further includes a driver that provides power for the movement of the conveyor vehicle between sections. It should be noted that when the driver is mounted on the conveyor, at least one driver must be present at the bottom of the conveyor vehicle to provide power as it moves on the conveyor. Alternatively, the driver can also be located at the bottom of the conveyor vehicle.

[0015] In this application, the conveying device includes a first conveying track, a second conveying track, a first connecting track, and a second connecting track.

[0016] Connecting track one and connecting track two are set at both ends of conveying track one and conveying track two to form a U-shaped circular conveying track;

[0017] The conveyor vehicle moves on conveyor track one, conveyor track two, connecting track one, and connecting track two. This forms an assembly line operation mode, shortening the original system's round-trip time, improving production efficiency, and meeting high-capacity requirements.

[0018] In this application, a shuttle bus is installed on the connecting track.

[0019] A shuttle bus is installed on the second connecting track;

[0020] Shuttle bus 1 transfers the transport vehicle from transport track 1 to transport track 2;

[0021] Shuttle bus 2 will transfer the transport vehicle from transport track 2 back to transport track 1;

[0022] Both shuttle bus 1 and shuttle bus 2 are equipped with reversing tracks corresponding to the positions of the conveyor tracks. The reversing tracks enable the conveyor vehicles to enter and leave the shuttle bus without obstacles, and to pass through the conveyor tracks without obstruction, thus forming an assembly line operation mode.

[0023] In this application, the feeding area and the longitudinal cutting area are arranged on the first conveyor track;

[0024] The cross-cutting area and the unloading area are located on the second conveyor track.

[0025] This configuration method helps save system layout space.

[0026] In this application, a turning table and a steam curing cart are independently provided in the material feeding area;

[0027] The unloading crane transports the billet to the turning table and then transfers the turned billet to the curing car. The turning table is used to turn the billet, effectively removing the top and bottom skins.

[0028] In this application, the continuous annular cutting system further includes a gantry frame;

[0029] The gantry crane spans across the loading and unloading areas;

[0030] Both the loading crane and the unloading crane are mounted on the gantry frame and their positions on the gantry frame are adjustable.

[0031] While saving system layout space, a gantry crane can be used to share the loading and unloading cranes, thus saving system equipment costs.

[0032] In this application, the conveyor is provided with a rotating shaft and a cleaning shaft at both ends. The rotating shaft is equipped with a limit wheel, which is located on the side of the conveying device. The rotating shaft and the cleaning shaft are connected by a belt drive. The bottom of the cleaning shaft is provided with a cleaning component for cleaning the surface of the conveying device.

[0033] In this application, the second conveying track is provided with an adjusting component on one side near the end of the connecting track and a positioning component on the other side. The adjusting component includes an adjusting plate, a track plate, and a driving component. The driving component is used to drive the adjusting plate to slide on the track plate.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] This invention utilizes a conveyor vehicle that travels in a loop along the conveying device, achieving a streamlined operation mode. This effectively solves the problem of long production cycles and inability to meet high-capacity requirements caused by the reciprocating operation mode in existing technologies. Furthermore, the conveying device is equipped with a driver, which allows for individual control of a single conveyor vehicle, enabling simultaneous operation at corresponding workstations. This shortens the cycle time, increases capacity, optimizes system layout, and saves equipment costs, among other advantages.

[0036] In this system, multiple conveyor vehicles operate simultaneously at different workstations. When one vehicle finishes cutting, the next vehicle can enter the cutting station at the same time, reducing the vehicle's reciprocating time, realizing continuous cutting of blocks / boards, and improving cutting efficiency.

[0044] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0045] A continuous circular cutting system for aerated concrete block panels includes a conveying device 3, a conveying vehicle 2 on the conveying device 3, the conveying vehicle 2 being used to hold the blanks, and the path of the conveying vehicle 2 on the conveying device 3 being a loop-shaped circulation.

[0046] The conveying device 3 is equipped with a feeding area, a longitudinal cutting area, a transverse cutting area, and a discharging area;

[0047] A separate loading crane 4 is set up in the loading area to transport the billet to the conveyor 2;

[0048] A longitudinal cutting machine 5 is independently set up in the longitudinal cutting zone, which longitudinally cuts the billet passing through it;

[0049] A cross-cutting machine 7 is independently set up in the cross-cutting zone, and the cross-cutting machine 7 cross-cuts the billet that passes through it;

[0050] A separate unloading crane 8 is set up in the palletizing area to unload the billet from the conveyor 2.

[0051] The conveying device 3 includes a first conveying track 31, a second conveying track 32, a first connecting track 33, and a second connecting track 34.

[0052] Connecting track 1 33 and connecting track 2 34 are set at both ends of conveying track 1 31 and conveying track 2 32 to form a U-shaped circular conveying track;

[0053] The conveyor 2 moves on conveyor track 1 31, conveyor track 2 32, connecting track 1 33 and connecting track 2 34.

[0054] By having the conveyor 2 complete a circular motion in a U-shape on conveyor track 31, conveyor track 32, connecting track 33 and connecting track 34, the conveyor 2 can achieve a production line operation mode, shorten the production cycle, and increase production capacity.

[0055] The cutting system also includes a driver 1, which is a combination of a friction wheel and a reduction motor. Refer to CN201710599591.2. Multiple drivers are provided, specifically distributed on the side of each track. The driver 1 provides power for the movement of the conveyor 2 in each section.

[0056] In the cutting system, a shuttle car 6 is provided on the connecting track 33;

[0057] A shuttle bus 210 is installed on connecting track 234;

[0058] Shuttle bus 6 transfers transport vehicle 2 from transport track 1 31 to transport track 2 32;

[0059] Shuttle bus 210 transfers transport vehicle 2 from transport track 232 back to transport track 131;

[0060] Both shuttle car 6 and shuttle car 10 are equipped with reversing tracks corresponding to the positions on the conveyor tracks. Shuttle cars 6 and 10 can transfer the conveyor car 2 between conveyor tracks 31 and 32, thus achieving a continuous, cyclical conveying path and continuous cutting. With the help of the drive unit 1, the conveyor car 2 at the corresponding workstation can perform the corresponding operation (cutting, flipping, or stacking).

[0061] In the cutting system, the feeding area and longitudinal cutting area are set on conveyor track 31, and the transverse cutting area and unloading area are set on conveyor track 32, which effectively saves system layout space.

[0062] In the cutting system, a turning table 9 and a curing car are independently provided in the unloading area. The unloading crane 8 transports the billet to the turning table 9 and transfers the turned billet to the curing car. The turning table 9 flips the billet and the bottom plate by 90 degrees, removing the top skin, bottom skin, and side skin at the ends. The turning table 9 can be a turning device in an existing system.

[0063] The continuous annular cutting system further includes a gantry frame.

[0064] The gantry crane spans above the loading and unloading areas. Both the loading crane 4 and the unloading crane 8 are mounted on the gantry crane and their positions on the gantry crane are adjustable.

[0065] In the cutting system, such as Figure 2 As shown, both ends of the conveyor 2 are equipped with a rotating shaft 21 and a cleaning shaft 22. A limiting wheel 23 is mounted on the rotating shaft 21 and is located on the side of the conveyor 3. The rotating shaft 21 and the cleaning shaft 22 are connected by a belt drive. A cleaning component 24 for cleaning the surface of the conveyor 3 is located at the bottom of the cleaning shaft 22. The cleaning component 24 has a disc-shaped structure and its bottom surface is made of a flexible material, such as sponge or polyurethane strip. The limiting wheel 23, in conjunction with the traveling wheels on the conveyor 2, restricts movement on the track, preventing horizontal movement relative to the track. Simultaneously, as the conveyor 2 moves, the limiting wheel 23 rotates along the side of the track, causing the cleaning component 24 to clean the top surface of the track, preventing dirt on the track surface from affecting the horizontal movement of the conveyor 2. Especially during longitudinal cutting, if the traveling wheels pass over dirt, they will bounce up and down, causing up and down movement of the cut surface and grooved surface of the billet layer, affecting product quality.

[0066] In the cutting system, such as Figures 3 to 5 As shown, the second conveying track 32 has an adjusting component on one side near the end of the connecting track 33, and a positioning component 321 on the other side. The adjusting component includes an adjusting plate 322, a track plate 323, and a driving component 324. The driving component 324 is used to drive the adjusting plate 322 to slide on the track plate 323. Because the longitudinally cut billet is transported to the end of the second conveying track 32 by the transfer car 6, the previous method of directly transporting it to the end position and then stopping it abruptly can cause the longitudinally cut billet to tilt to one side. Although this does not affect the cross-cutting operation, it does affect the flipping operation, which can lead to billet deformation and quality problems. Therefore, the shuttle car 6 is slowed down and stopped before reaching the positioning component 321. The driving component 324 (cylinder, hydraulic cylinder or electric cylinder) drives the adjusting plate 322 to move along the track plate 323. The end of the adjusting plate 322 is provided with an inclined plate. The end of the inclined plate near the connecting channel 33 gradually deviates from the positioning component 321. The adjusting plate 322 causes the shuttle car 6 to fit against the positioning component 321, ensuring that the connecting channel 33 and the conveying track 32 are in corresponding positions.

[0067] In practical implementation:

[0068] 1) The billet that has been statically stopped and gasified is transported to the fixed area directly below the loading crane 4. The loading crane 4 hooks the bottom plate and the billet and lifts it onto the conveyor 2.

[0069] 2) The driver starts, and the transport vehicle 2 (including the base plate and billet) travels on the transport track 31 and passes through the longitudinal cutting machine 5, and finally travels to the waiting position after longitudinal cutting.

[0070] During transportation, the slitting machine 5 can horizontally cut the whole square blank into the corresponding number of layers according to the size requirements. In the process, side cutting and grooving operations can also be completed.

[0071] 3) After longitudinal cutting is completed, the conveyor 2 is transported to the shuttle car 6. The shuttle car 6 moves from the waiting position after longitudinal cutting on the conveyor track 31 to the waiting position before transverse cutting on the conveyor track 32, and allows the conveyor 2 to leave the shuttle car 6. The shuttle car 6 then moves from the end of the conveyor track 32 to the end of the conveyor track 31 to wait for the next conveyor 2.

[0072] 4) After the blank on the previous conveyor 2 is transversely cut, it is transported to the next station. The conveyor waiting for transverse cutting is transported to the bottom of the transverse cutting machine 7. The transverse cutting machine 7 is started and cuts the whole mold blank into blocks of different lengths according to the size requirements.

[0073] 5) After the cross-cutting is completed, the conveyor 2 is transported to the underside of the unloading crane 8. At the same time, the conveyor 2, which was originally located under the unloading crane 8, is transported to the next station. The unloading crane 8 lifts the cut billet and base plate to the tilting table 9, and then lifts the processed billet on the tilting table 9 to the curing car. Then, it waits for the next conveyor 2.

[0074] 6) At this time, there are no blanks and bottom plates on the conveyor 2. The conveyor 2 is transported to the transfer car 2 10 by the drive 1. The transfer car 2 10 moves from the second conveyor track 2 32 to the first conveyor track 31 and allows the conveyor to leave the transfer car 2 10. It then moves from the end of the first conveyor track 31 to the end of the second conveyor track 2 32 to wait for the next conveyor 2.

[0075] 7) After the conveyor 2 gets off the shuttle car 210, it is first transported to the waiting position before longitudinal cutting. When the conveyor 2 under the feeding crane 4 is longitudinally cutting, the conveyor 2 is transported to the feeding crane 4 directly below it to wait for the freshly fermented green body to be placed. Thus, the conveyor 2 completes one cycle.

[0076] In this system, multiple conveyor vehicles 2 move continuously forward along a circular line, enabling continuous cutting, improving production efficiency, reducing the reciprocating time of the trolleys in previous processes, and meeting the needs of current high-capacity processes.

[0077] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
