[0002] Certain fillers are required in the production and manufacturing of aircraft seats, and this type of filler is mostly made of polyurethane rigid foam. Polyurethane rigid foam is a high-molecular polymer made of isocyanate and polyether as the main raw materials. It is mixed with special equipment under the action of various additives such as foaming agents, catalysts, flame retardants, etc., and foamed on-site by high-pressure spraying. There are two types of polyurethane foam: soft foam and hard foam. Soft foam has an open-cell structure, while hard foam has a closed-cell structure.

[0003] During the production of rigid polyurethane foam plastics, it is usually necessary to foam the rigid polyurethane foam plastics. When the existing foaming equipment is in use, the box cover of the foaming box is mostly fixed by bolts or connected and fixed by industrial buckles. When disassembling, it is necessary to manually remove multiple bolts or open multiple industrial buckles before the box cover can be removed. The disassembly is cumbersome and inconvenient, which seriously affects the use. Utility Model Content

[0018] Example 1:

[0019] like Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the overall structure of a mixer for processing aircraft seat back foam. Figure 2 It is a cross-sectional view of the mixing tank 101. The utility model provides a mixer for processing foam for aircraft seat backrests: comprising a mixing tank 101 and an auxiliary mechanism, wherein the auxiliary mechanism comprises a top cover 103, a feeding pipe 104, a V-shaped guide seat 105, a fixing plate 106, a rotary hydraulic cylinder 107, a pressure block 108, a discharge valve 109, a V-shaped stirring rod 114, a hoisting device and a stirring device, wherein the hoisting device comprises a first hanging ring 110 and a second hanging ring 111, and the stirring device comprises a stirring motor 112 and a stirring frame 113. The aforementioned scheme can realize quick and convenient disassembly of the equipment top cover 103 when it is necessary to disassemble it during processing. It can be understood that the aforementioned scheme can realize quick and convenient disassembly and quick installation of the top cover 103.

[0020] In this embodiment, a plurality of supporting legs 102 are welded to the bottom of the mixing tank 101 for working support. Meanwhile, through holes are provided on the bottom abutment plate for easy fixation by anchor bolts.

[0021] Among them, the cross-section of the top cover 103 is T-shaped, and is detachably connected to the stirring tank 101 and located at the top of the stirring tank 101. The feeding pipe 104 is welded to the feeding port of the top cover 103. The V-shaped guide seat 105 is fixedly connected to the stirring tank 101 and is located at the bottom inner side of the stirring tank 101. The fixed plate 106 is welded to the outer wall of the stirring tank 101, and three pieces are evenly arranged at annular intervals. The angle hydraulic cylinder 107 is fixed on the top of the fixed plate 106, and its corresponding oil port is connected to the hydraulic valve seat of the external hydraulic station through a movable oil pipe. The pressure block 108 is installed on the output end of the angle hydraulic cylinder 107. The discharge valve 109 is fixedly connected to the stirring tank 101 and is located outside the discharge port of the stirring tank 101. The lifting device is symmetrically arranged on the top of the top cover 103, and the stirring device is arranged on the side of the top cover 103 close to the stirring tank 101. The cross-section of the top cover 103 is T-shaped, and its bottom stepped portion can directly slide into the top cavity of the mixing tank 101. The bottom of the feeding pipe 104 is welded to the top cover 103, and the V-shaped guide seat 105 is fixed to the bottom of the mixing tank 101 by bolts. The bolts are set upward from the outside of the bottom of the mixing tank 101 to achieve tension. The fixed plate 106 is welded to the outer wall of the mixing tank 101, and three pieces are set at an interval of 120°. The model of the angular hydraulic cylinder 107 is SRCR-50x90. When it is in action, it rotates 90° counterclockwise to the left and presses down. The cylinder body is fixed to the fixed plate 106 by bolts, and its corresponding oil port is connected to the hydraulic valve seat of the external hydraulic station through an active oil pipe. The pressure block 108 is fixedly installed on the output end of the angular hydraulic cylinder 107 by bolts, and the mounting plate of the discharge valve 109 is fixed to the outside of the discharge port of the mixing tank 101 by bolts. The lifting device is used to assist in the disassembly of the top cover 103, and the stirring device is used to stir and mix materials.

[0022] Secondly, the first lifting ring 110 is threadedly connected to the top cover 103 and is located on one side of the top cover 103. The second lifting ring 111 is threadedly connected to the top cover 103 and is located on the side of the top cover 103 away from the first lifting ring 110, and is symmetrically arranged with the first lifting ring 110. The first lifting ring 110 and the second lifting ring 111 are of the same size, and the external threaded ends at the bottom can directly mate with the threaded holes on the top cover 103 for installation. When installing or removing the top cover 103, the first lifting ring 110 and the second lifting ring 111 can be directly threaded with a lifting rope to install or remove the top cover 103.

[0023] Then, the stirring motor 112 is fixedly connected to the top cover 103 and is located on the top of the top cover 103. The top connecting shaft of the stirring frame 113 is connected to the output shaft of the stirring motor 112 through a rigid coupling and is located in the stirring tank 101.

First, when processing materials, the materials are first fed in through the feeding pipe 104. At this time, the discharge valve 109 is closed. Then, after the materials are fully fed in, the stirring motor 112 is controlled to drive the stirring frame 113 and the V-shaped stirring rod 114 to rotate, so that the materials can be stirred and mixed. After the mixing is complete, the discharge valve 109 is opened to discharge the mixed materials. When the top cover 103 needs to be disassembled, the three rotary hydraulic cylinders 107 are directly controlled to move, which will drive the pressing block 108 to rotate and move away from the top of the top cover 103, so that the top cover 103 can be quickly loosened. Then, the lifting device can be used to quickly lift and remove it, so as to achieve quick disassembly. Compared with traditional bolt fixing or industrial buckle fixing, the top cover 103 is faster to disassemble or install, thereby achieving quick and convenient disassembly when the top cover 103 of the equipment needs to be disassembled during processing.
