Description

Technical Field

[0001] The invention relates to the technical field of aerated concrete blank production, in particular to a plate turning table. Background Art

[0002] Aerated concrete is a lightweight porous silicate product made from siliceous materials (sand, fly ash and silicon-containing tailings, etc.) and calcareous materials (lime, cement) as the main raw materials, with the addition of a gas-generating agent (aluminum powder). It is made through a process of batching, mixing, pouring, pre-curing, cutting, autoclaving, and curing.

[0003] During the processing of the plate, it needs to be flipped 90° to facilitate subsequent processing operations. The floor turning table currently used by our company is a utility model patent that our company has disclosed (application date: 2020.06.12, application number: 202021084422.9, invention name: A floor turning table in front of a kettle). Although this floor turning table can meet the purpose of driving the blank to flip, this floor turning table needs to be used in conjunction with the side plate of the conveying plate (as shown in the attached patent). Figure 1 The efficiency of the turning table is affected by the efficiency of the side plate transfer during use. Therefore, there is an urgent need for a turning table that can improve the efficiency of plate movement. The plates have a certain degree of stickiness, and the flipping detachment of the conventional side plates can easily cause damage to the end faces of the plates.

[0004] In view of the above-mentioned defects, the designer actively conducts research and innovation in order to create a plate turning table to make it more valuable for industrial use. Summary of the invention

[0005] In order to solve the above technical problems, the object of the present invention is to provide a plate turning table.

[0006] The present invention discloses a plate turning table, comprising a bracket, on which a plurality of cross beams for supporting are arranged, on which a sliding feeding rack is installed through a slide rail, and on one side of the bracket there is a side supporting rack that can be turned over;

[0007] There are multiple synchronously rotating conveying rollers on the feeding rack;

[0008] The side support frame relies on the connecting shaft to perform 90° flipping movement.

[0009] This type of plate turning table first provides a conveying mechanism, which is a plurality of synchronously rotating conveying rollers. The conveying rollers can drive the plates to move when rotating, so that the plates can be separated from the side plates to achieve the purpose of automatic conveying. Subsequently, the plates can be turned over by rotating the side support frame to facilitate subsequent operations.

[0010] Furthermore, both ends of the conveying roller on the feed rack are movably installed through bearing seats and bearings. The conveying roller has a transmission rod protruding from the bearing seat on the side away from the side support frame. Two parallel sprockets are installed on the transmission rod. The chains on adjacent transmission rods are installed on the sprockets in a staggered manner. The driving teeth of the driving motor installed on the side of the feed rack are connected to the sprocket on the transmission rod close to the driving motor through the driving chain.

[0011] The conveyor rollers on the feeding rack realize transmission by driving the corresponding chains through the driving motor, and each conveyor roller has a corresponding connected chain, which realizes the purpose of synchronous rotation of the conveyor rollers and meets the purpose of conveying the plates, avoiding the situation where the rotation speed between the conveyor rollers is not constant and causes wear of the plates.

[0012] Furthermore, racks are installed on both sides of the bottom of the feeding rack, and a synchronization rod fixing seat is provided in the middle of the bracket, a synchronization rod bearing seat is fixed on the synchronization rod fixing seat, a synchronization shaft is movably installed in the synchronization rod bearing seat through a bearing, and both ends of the synchronization shaft are synchronization teeth, which are meshed with the racks. A mobile hydraulic cylinder is installed on the bracket, and the front end of the telescopic rod of the mobile hydraulic cylinder is fixedly connected to the feeding rack.

[0013] The entire feed rack is driven to translate by a mobile hydraulic cylinder installed on the bracket, so that the position of the feed rack can be transferred between the feed track and the flipping station, thereby improving work efficiency and ensuring the integrity of the plate structure.

[0014] Furthermore, the side support frame includes a plurality of neatly arranged right-angled flip plates, and the rear side of the flip plate has a baffle in contact with the ground support after flipping.

[0015] The maximum flipping angle of the flip board is limited by the ground support to prevent the board on the flip board from being too heavy, causing the flipping angle of the flip board to exceed 90° and causing the board to slip.

[0016] Furthermore, the corner of the flip plate is installed on the flip plate fixing seat through a connecting shaft. A push rod extending downward is provided on the flip plate. The middle of the push rod is movably connected to the telescopic rod of the flip plate hydraulic cylinder through a pin shaft. The tail end of the flip plate hydraulic cylinder is fixed to the bracket through a pin shaft and a mounting seat.

[0017] The flipping operation of the flip plate is performed by the flip plate hydraulic cylinder. When the flip plate hydraulic cylinder contracts, it drives the flip plate to flip. After the flip plate hydraulic cylinder is reset, the flip plate is reset.

[0018] Furthermore, the flip plate has a slidable sliding plate on one side of the baffle plate.

[0019] The sliding plate can perform a sliding operation. After the flipping is completed, the sliding plate drives the plate to move outward a certain distance, so that the plate is separated from the initial load-bearing part of the flip plate, avoiding the situation in which the plate is damaged due to direct sliding between the plate and the flip plate during subsequent handling operations.

[0020] Furthermore, a slide rail is provided on the inner side of each flip plate, and a slider matching the slide rail is fixed to the inner side of each sliding plate by bolts.

[0021] The sliding plate moves by means of a slider installed on the inner side thereof cooperating with a slide rail on the inner side of the flip plate.

[0022] Furthermore, each sliding plate has an end plate extending toward the inside of the flip plate at the upper end, a pull rod is movably installed on the lower end of the end plate through a pin, a right-angle push rod is movably installed on the lower end of the pull rod through a pin, and the corner of the right-angle push rod is movably installed on the flip plate through a pin. After the flip plate is flipped 90°, the right-angle push rod contacts the upper end of the ground support and promotes the rotation of the right-angle push rod.

[0023] The outer side of the right-angle push rod contacts the upper end of the ground support after the flip plate flips 90 degrees, and the other end of the right-angle push rod drives the pull rod to push outward, thereby driving the sliding plate to move a certain amount, thereby realizing automatic displacement.

[0024] Furthermore, inside the flip plate, a tension spring fixing rod is installed below the pull rod, the upper end of the tension spring is fixed to a pin shaft for movable connection between the lower end of the pull rod and the right-angle push rod, and the lower end of the tension spring is fixedly connected to the tension spring fixing rod.

[0025] After the flip plate is reset, the sliding plate is driven to reset by the tension of the tension spring.

[0026] Furthermore, the lower end of the right-angle push rod is open, and a roller is movably installed in the opening via a pin.

[0027] The roller at the end of the right-angle push rod causes sliding friction when it contacts the ground support, thus avoiding direct collision and extending the service life of the right-angle push rod.

[0028] Through the above scheme, the present invention has at least the following advantages: when this plate turning table is in use, the plate is driven to move forward by the synchronously rotating conveying rollers, and after the plate is completely conveyed to the flipping plate, it is flipped by the flipping plate without using the side plates, and after the flipping is completed, the plate can be driven to move outward in a small range by a sliding mechanism, so that the plate is detached from one side of the flipping plate, thereby avoiding the situation where the plate is damaged due to friction when other handling devices lift the plate.

DETAILED DESCRIPTION

[0042] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0043] See also Figure 1-3 The initial position of the feeding rack 4 on the local turning table is located on the right side of the bracket 1 of the device ( Figure 3 As shown in the figure, the conveying roller 6 on the upper part is in the same straight line with other conveying mechanisms for feeding in the workshop. The plate is conveyed to the feeding rack 4 through the conveying mechanism. At this time, the rotation of the conveying roller 6 on the feeding rack 4 facilitates the introduction of the feeding rack. Finally, the side support frame 5 is flipped to complete the 90° flipping operation of the plate.

[0044] See also Figure 4 Figure 5 The drive motor 11 and the feeding rack 4 are fixedly installed, so the drive motor 11 can move synchronously with the feeding rack 4. The drive motor 11 matches the sprocket 9 installed on the transmission rod 8 closest to it through the driving chain 12. The transmission rod 8 and the conveying roller 6 are integrated. Each transmission rod 8 has a sprocket, and each sprocket is connected by a chain 10. Under the transmission of the chain, the purpose of synchronously driving each conveying roller 6 can be met, avoiding inconsistent linear speeds on the surface of the conveying roller 6, resulting in friction on the bottom of the plate and damage to the plate.

[0045] See also Figure 2 and Figure 6In order to facilitate the forward and backward movement of the feeding rack 4, at least two groups of mobile hydraulic cylinders 21 are installed between the feeding rack 4 and the bracket 1. When the mobile hydraulic cylinder 21 is telescopic, the slider installed under the feeding rack 4 cooperates with the slide rail 3 on the middle cross beam 2 of the bracket 1 to provide a sliding track. At this time, the feeding rack 4 can move forward and backward, and when moving, the meshing relationship between the gear rail 33 installed at the bottom of the feeding rack 4 and the synchronous tooth 16 at the end of the synchronous shaft 15 makes the moving speed of the two ends consistent, ensuring that the feeding rack 4 is driven to move synchronously. Because the length of the entire plate is basically 6m, if the moving speed is not consistent, it is easy to bump, resulting in damage to the plate.

[0046] In order to facilitate the installation of the synchronization shaft 15, a synchronization rod fixing seat 13 is installed in the middle of the bracket 1 by welding or bolting. The synchronization shaft 15 is installed in the synchronization rod bearing seat 14 through a bearing, so that the synchronization shaft 15 can rotate relying on the synchronization rod bearing seat 14.

[0047] See also Figure 1 and Figure 7 A flip plate 17 is installed between two adjacent conveying rollers 6. The main body of the flip plate 17 is a right-angle steel structure. Figure 1 The position of the middle flip plate 17 is the initial state. At this time, the upper edge of the flip plate 17 is slightly lower than the upper edge of the conveying shaft 6, or is flush with the upper edge of the conveying shaft 6, which is convenient for conveying the plate to the entire ground flip table. The function of the ground support 18 is to provide support for the flip plate 17 after flipping, to prevent the flip plate 17 from flipping too much and causing the plate placed on the flip plate 17 to slip.

[0048] See also Figure 7 and Figure 8 The turning plate hydraulic cylinder 24 which is concealed on the bracket 1 pushes the push rod 23 under the turning plate 17, driving the turning plate 17 to turn over, thereby driving the plate to rotate 90 degrees.

[0049] See also Figure 8 After the flip plate 17 flips 90°, the sliding plate 20 faces upward. At this time, the sliding plate 20 with the plate placed thereon is moved outward by a certain distance through the displacement mechanism, and the other side of the plate is separated from one surface of the flip plate 17. At this time, when the plate is transported through the transfer mechanism, sliding friction between the plate and the flip plate 17 is avoided, ensuring that the surface of the plate is flat.

[0050] Furthermore, a slide rail (25) is provided on the inner side of each flip plate (17), and a slider (26) matching the slide rail (25) is fixed to the inner side of each sliding plate (20) by bolts.

[0051] See also Figure 8 and Fig. 9 The sliding plate 20 and the flip plate 17 are installed by means of a slide rail 25 and a slider 26 to facilitate sliding.

[0052] See also Figure 8-10 The extension of the sliding plate 20 is provided with thrust by the right-angle push rod 29. After the flip plate 17 flips, the right-angle push rod 29 contacts a bolt protruding from the ground support 18, driving the right-angle push rod 29 to rotate. After the right-angle push rod 29 rotates, it can push the pull rod 28 to move outward, and then drive the entire sliding plate 20 to move outward first through the end plate 27, thereby achieving the purpose of taking the plate away from the flip plate 17.

[0053] See also Figure 8-10 After the plate on the flip plate 17 is removed, the flip plate 17 is reset. At this time, the sliding plate 20 can be moved down and reset by its own weight. When necessary, the tension spring 31 can provide tension to facilitate reset. The tension spring can also be used for the purpose of limiting to prevent the sliding plate 20 from moving when flying.

[0054] See also Fig. 9 In order to facilitate the right-angle push rod 29 to contact with the bolt installed on the ground support 18, a roller is installed on the right-angle push rod 29 through a pin shaft, and contact is made by rolling friction, thereby extending the service life of the right-angle push rod 29.

[0055] The working principle of the present invention is as follows:

[0056] First, the feeding frame 4 of this device is in Figure 3 The position on the middle right side, after the plate is transported to the feeding rack 4 through the feeding mechanism, the mobile hydraulic cylinder 21 is started to drive the feeding rack 4 to move to the left. When it moves to the flipping position, the flip plate 17 is flipped 90° by the operation of the flip plate hydraulic cylinder 24, and the right-angle push rod 29 on the flip plate 17 contacts the bolt on the ground support 18. The right-angle support 29 and the matching pull rod 28 are used to drive the sliding plate 20 to move outward, so that the other side of the plate is separated from one surface of the flip plate 17, which is convenient for subsequent operations. At the same time, the baffle 19 on the flip plate 17 contacts the upper end of the ground support 18, and the ground support 18 is used to provide supporting force for the flip plate. After the plate is taken, the flip plate hydraulic cylinder 24 first drives the flip plate 17 to reset, and then the mobile hydraulic cylinder 21 drives the feeding rack 4 to reset, completing the operation of one process, and repeating the operation can cycle the work.
