Description

Technical Field

[0001] This utility model relates to the field of polyurethane foam production technology, and in particular to a mixing tank for polyurethane foam production. Background Technology

[0002] Polyurethane foam is a high molecular polymer made from isocyanate and polyether as the main raw materials, and is produced by mixing with various additives such as foaming agents, catalysts, and flame retardants, and then foaming on-site through high-pressure spraying. In the production process of polyurethane foam, a mixing tank is required to mix the polyurethane foam raw materials.

[0003] Patent publication number CN112755888A discloses a food ingredient container, belonging to the technical field of food ingredient container technology, including a base plate. This invention relates to a food ingredient container that incorporates a damping spring. During the operation of the drive motor, the container body vibrates; the magnetic effect of the damping spring reduces this vibration. A sliding plate is included; during vibration, the sliding plate slightly slides left and right within a first T-slot, preventing friction between the sliding plate and the base plate. A handwheel, threaded rod, moving block, and limiting rod are included. After a period of use, the damping spring can be easily disassembled for maintenance and replacement. Disassembly involves manually rotating the handwheel, causing the threaded rod to rotate. This moves the moving block upwards along with the limiting rod. When the limiting rod is completely separated from the insertion block, a cylinder is activated to detach the insertion block from the limiting block. A second slider prevents the moving block from rotating in place during its movement.

[0004] In the aforementioned patent, although the vibration of the mixing tank can be reduced by setting damping springs, the end of the damping spring furthest from the mixing tank is directly fixed, while the end closer to the mixing tank is fixed by plugging. This arrangement means that when damping the mixing tank, the damping springs need to be fixed one by one, and when the damping is removed, the connection between the damping springs and the mixing tank needs to be removed one by one. This process is cumbersome, time-consuming, affects the work efficiency of the staff, and reduces the practicality of the mixing tank. Utility Model Content

[0035] A movable component is provided on the outer surface of the bottom end of the support leg 2. The movable component includes a caster wheel 24 and a sliding sleeve 25. The caster wheel 24 is fixedly installed on the bottom end of the support leg 2. The sliding sleeve 25 is fitted on the outer surface of the bottom end of the support leg 2.

The support leg 2 and the caster wheel 24 pass through the support ring 27. A limit bolt 28 is threadedly connected to the outer surface of the sliding sleeve 25. The limit bolt 28 extends into the interior of the sliding sleeve 25 and is inserted into the support leg 2.

[0036] By incorporating casters 24, sliding sleeves 25, limiting blocks 26, support rings 27, and limiting bolts 28, the mixing tank can be easily moved. A retractable caster 24 is provided at the bottom of the support leg 2, allowing for convenient and quick movement of the mixing tank. Furthermore, retracting the caster 24 into the sliding sleeve 25 enables rapid positioning of the mixing tank. Additionally, the support ring 27 increases the contact area between the support leg 2 and the ground, enhancing the stability of the mixing tank.

[0037] Working principle: Before mixing the raw materials of polyurethane foam using the mixing tank, place the mixing tank on the upper surface of the base 11, so that the tank body 1 is between the two clamping plates 17. Then, start the two electric push rods 13. When the electric push rods 13 extend, they push the movable plate 14 towards the tank body 1. The slider 15 slides inside the slide groove. At the same time, the movable plate 14 drives the clamping plates 17 to move closer to the tank body 1 through the telescopic rod 16. When the two clamping plates 17 contact the outer surface of the tank body 1, they clamp the tank body 1. At the same time, the movable plate 14 continues to move, so that the telescopic rod 16 shortens and the damping spring 18 is compressed and deformed. When the movable plate 14 moves to the appropriate position, control the electric push rods 13 to stop extending or shortening. The above operations complete the positioning and vibration reduction of the mixing tank.

[0038] When mixing the raw materials for polyurethane foam using the mixing tank, the raw materials are added into the tank 1 through the feed hopper 3. At the same time, the motor 5 is started. When the motor 5 moves, it drives the rotating rod 6 to rotate inside the tank 1, which in turn drives the actuating rod 8, the cutting blade 9, and the stirring rod 10 to rotate. The guide plate 7 causes the raw materials to fall to the middle of the tank 1. The actuating rod 8 sweeps off the raw materials remaining on the guide plate 7. Then, the cutting blade 9 beats and cuts the clumps of raw materials. The stirring rod 10 then mixes the raw materials. During the mixing process, when the mixing tank vibrates, the tank 1 shakes, which pushes the clamping plate 17, causing it to move. This further compresses the damping spring 18. When the damping spring 18 returns to its original position, it pushes the clamping plate 17 back to its original position. During this process, the damping spring 18 buffers the force generated by the vibration of the tank 1, thus completing the vibration reduction function. After the raw materials are mixed, the valve on the discharge pipe 4 is opened, and the polyurethane foam can be discharged through the discharge pipe 4.

[0039] When it is necessary to move the mixing tank, rotate the limiting bolt 28 to move it away from the sliding sleeve 25, thereby releasing the restriction on the sliding sleeve 25. Then pull the sliding sleeve 25 upward, and the sliding sleeve 25 slides upward along the outer surface of the support leg 2. The limiting block 26 slides inside the limiting groove, while driving the support ring 27 to move upward. After the universal wheel 24 at the bottom of the support leg 2 is exposed, rotate the limiting bolt 28 in the opposite direction to fix the sliding sleeve 25 again, and the mixing tank can be moved. Repeat the above operation in reverse to store the universal wheel 24 and position the mixing tank.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
