Description

Technical Field

[0001] The utility model relates to production equipment for a plastic membrane shell for concrete buildings, in particular to a device for facilitating the disassembly of the membrane shell. Background Art

[0002] Concrete building plastic membrane shell is a molding mold widely used in the field of modern construction. It is mainly used to manufacture ribbed floor slabs, especially in high-rise buildings. This mold shell is usually composed of a three-layer structure of a coating layer, a non-woven fabric layer and a plastic layer. It has the characteristics of high strength, light weight and good durability.

[0003] In the production process of plastic membrane shell for concrete buildings, hydraulic press plays a vital role. Through the high pressure of hydraulic press, the plastic raw materials are formed in the bottom mold and the top mold. After the membrane shell is cooled and solidified, the hydraulic press is opened to take out the formed membrane shell.

[0004] In the existing production process, due to the limited space between the workbench and the movable crossbeam of the hydraulic press, and the different sizes and shapes of molds of different types of membrane shells, the membrane shells usually need to be removed from the hydraulic press manually. Due to the certain adhesion between the membrane shell and the bottom mold, it is difficult to remove the membrane shell from the bottom mold of the hydraulic press manually. During the removal process, the membrane shell is easily damaged due to uneven force, which affects the product yield, and workers may also be injured due to improper operation.

[0005] In summary, a device for facilitating the disassembly of the membrane shell is needed to solve the problems existing in the prior art. Summary of the invention

[0033] The bottom mold 102 is arranged on the workbench 101, and the top mold is arranged on the movable crossbeam 104. When the membrane shell 7 is formed, the movable crossbeam 104 cooperates with the workbench 101 to make the top mold and the bottom mold 102 fit tightly. An ejection cylinder is arranged in the workbench 101, and the push rod 103 of the ejection cylinder is arranged around the bottom mold 102.

[0034] After the membrane shell 7 is formed, it remains on the bottom mold 102 . The movable crossbeam 104 drives the top mold and the membrane shell 7 to separate. The push rod 103 of the ejection cylinder is used to lift the edge of the membrane shell 7 to reduce the adhesion between the membrane shell 7 and the bottom mold 102 .

[0035] The disassembly device includes a conveyor belt 2, a column lift 3, and a transverse movement assembly. The conveyor belt 2 is arranged on the ground. The conveyor belt 2 is located on the central axis of the hydraulic press 1. The column lift 3 includes four lifting columns. The four lifting columns perform lifting actions synchronously. Two lifting columns are respectively arranged on both sides of the conveyor belt 2.

[0036] The transverse movement assembly includes a screw assembly 4, a support frame 5 and a clamp 6. The screw assemblies 4 are respectively provided on both sides of the conveyor belt 2. Each screw assembly 4 is connected to two lifting columns, and the two lifting columns jointly drive the screw assembly 4 to move closer to or away from the conveyor belt 2.

[0037] The support frame 5 is arranged between the screw assembly 4, and the support frame 5 includes a pair of first connecting rods parallel to each other and a pair of second connecting rods parallel to each other. The first connecting rod and the second connecting rod are perpendicular to each other. The clamping jaws 6 are arranged at the heads of the pair of first connecting rods, and the first connecting rod is connected to the screw assembly 4 through the second connecting rod.

[0038] The screw assembly 4 includes a housing, a drive motor, a screw and a screw nut. The drive motor and the screw are arranged on the housing. The lifting column drives the housing to rise and fall. The drive motor is used to drive the screw to rotate. The screw nut is threadedly connected to the screw.

[0040] Five vacuum suction cups 603 are provided on the first frame 601, and the vacuum suction cups 603 are respectively arranged at the center and four corners of the first frame 601. The vacuum suction cups 603 on the first frame 601 are used to adsorb the top surface of the membrane shell 7. Two vacuum suction cups 603 are provided on the second frame 602, and the vacuum suction cups 603 are arranged at the same height. The vacuum suction cups 603 on the second frame 602 are used to adsorb the sides of the membrane shell 7.

[0042] The second frame 602 is perpendicular to the first frame 601 under the action of gravity. When the clamp 6 descends, the vacuum suction cup 603 on the second frame 602 contacts the inclined side of the membrane shell 7.

[0043] The working method of the first embodiment is as follows:

[0044] After the membrane shell 7 is formed in the hydraulic press 1, the movable crossbeam 104 drives the top mold and the membrane shell 7 to separate, the column lift 3 lifts the transverse movement assembly, and the screw assembly 4 sends the clamping jaw 6 between the top mold and the bottom mold 102 of the hydraulic press 1 through the support frame 5, so that the clamping jaw 6 is located above the membrane shell 7.

[0045] The push rod 103 of the ejection cylinder lifts the edge of the membrane shell 7, and the column lift 3 lowers the transverse movement assembly, so that the first frame 601 of the clamp 6 contacts the top surface of the membrane shell 7, and each vacuum suction cup 603 is started to make the clamp 6 absorb the membrane shell 7.

[0046] The column lift 3 lifts the transverse movement assembly, so that the clamp 6 removes the membrane shell 7 from the bottom mold 102, and the screw assembly 4 moves the clamp 6 to above the conveyor belt 2 through the support frame 5. The column lift 3 lowers the transverse movement assembly, so that the membrane shell 7 is close to the conveyor belt 2, and each vacuum suction cup 603 is closed, so that the membrane shell 7 falls onto the conveyor belt 2, and the conveyor belt 2 sends the membrane shell 7 to the next step for processing.
