Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically a polyurethane mixing equipment. Background Technology

[0002] Polyurethane resin is a polymer material produced by the polymerization reaction of isocyanate and polyol. Its molecular structure contains urethane groups, which makes it highly tunable. It can be made into various forms of products such as foam, elastomer, and coating by changing the raw material ratio.

[0003] Existing methods for mixing polyurethane resins primarily utilize stirred reactors. These reactors typically consist of a tank, a rotating rod, and stirring blades. In some cases, the stirring blades are directly fixed to the rotating rod, allowing the rod's rotation to drive the blades and thus achieve mixing. However, this method results in a large overall size, making installation cumbersome. Furthermore, replacing damaged stirring blades is inconvenient, often requiring users to replace both the rotating rod and the stirring blades together, which is costly. To address these issues, we offer polyurethane mixing equipment. Utility Model Content

[0004] 1) Technical problems to be solved

[0005] This utility model proposes a polyurethane mixing device, which solves the problem of costly replacement of the rotating rod and mixing blade together by means of the cooperation between components such as the threaded rod and the push block.

[0006] (ii) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a polyurethane mixing device, comprising a tank, a top cover installed on the upper surface of the tank, a horizontal plate connected inside the tank, a rotating rod rotatably connected inside the horizontal plate, and a positioning ring connected to the outer surface of the rotating rod;

[0008] The outer surface of the positioning ring is connected to a threaded rod, the outer surface of the threaded rod is rotatably connected to a positioning block, the outer surface of the threaded rod is threadedly connected to a protective block, the outer surface of the positioning block is connected to an installation block, the outer surface of the installation block is connected to a positioning rod, and the outer surface of the positioning rod is rotatably connected to a stirring blade.

[0009] A push rod is slidably connected inside the stirring blade. One end of the push rod contacts a push block. An insert rod is connected to the outer surface of the push block. The end of the insert rod away from the push block contacts a limit rod.

[0010] Furthermore, a motor is mounted on the upper surface of the top cover, and the output end of the motor is connected to the upper surface of the rotating rod.

[0011] Furthermore, the outer surface of the rotating rod is rotatably connected to the interior of the top cover, and the outer surface of the rotating rod is rotatably connected to the interior of the tank.

[0012] Furthermore, a barrier block is connected to the outer surface of the push rod, and the outer surface of the barrier block is slidably connected to the inside of the stirring blade.

[0017] (iii) Beneficial effects:

[0018] Compared with existing technologies, this polyurethane mixing equipment has the following advantages:

[0019] I. This polyurethane mixing equipment, through the cooperation between components such as the threaded rod and the push block, allows the protective block to be disassembled. After removing the protective block, the user can remove the positioning block along with the mixing blade. This eliminates the need to replace the threaded rod when the mixing blade is damaged, allowing the equipment to replace the mixing blade directly. The push block is movable, and after the push block is pulled out from the mixing blade, the mixing blade can rotate around the positioning rod, allowing the position of the mixing blade to be adjusted and making it easier to insert the mixing blade into the tank. This solves the problem of the wasteful cost of replacing the rotating rod and the mixing blade together.

[0020] Second, this polyurethane mixing equipment, through the cooperation between components such as the insert rod and the barrier block, allows the push block to move so that the insert rod can move. The movement of the insert rod can push the limit rod out of the positioning block, thereby allowing the positioning block to rotate. The user can move the push rod by pushing the barrier block, which makes it convenient for the user to move the position of the push rod. It is very easy to use. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] The motor 16 in this utility model is a common electrical device in the prior art, and this application will not elaborate on its model or internal structure.

[0030] like Figure 1-5 As shown, this utility model provides a technical solution: a polyurethane mixing device, including a tank 1, a top cover 2 installed on the upper surface of the tank 1, a horizontal plate 3 connected inside the tank 1, a rotating rod 4 rotatably connected inside the horizontal plate 3, a positioning ring 5 connected to the outer surface of the rotating rod 4, and a movable plate provided inside the top cover 2. The user can open the top cover 2 by moving the plate. The tank 1 will fix the position of the horizontal plate 3, and the horizontal plate 3 will reduce the vibration generated when the rotating rod 4 rotates. When the rotating rod 4 rotates, it will rotate with the positioning ring 5.

[0031] The outer surface of the positioning ring 5 is connected to a threaded rod 6. The outer surface of the threaded rod 6 is rotatably connected to a positioning block 7. The outer surface of the threaded rod 6 is threadedly connected to a protective block 8. The outer surface of the positioning block 7 is connected to a mounting block 9. The outer surface of the mounting block 9 is connected to a positioning rod 10. The outer surface of the positioning rod 10 is rotatably connected to a stirring blade 11. The positioning ring 5 restricts the position of the threaded rod 6. The positioning block 7 can be fitted onto the surface of the threaded rod 6. The user can restrict the position of the positioning block 7 between the positioning ring 5 and the mounting block 9 by installing the protective block 8. However, the protective block 8 will not be tightly attached to the positioning block 7. The positioning block 7 will fix the position of the mounting block 9. The stirring blade 11 can rotate around the positioning rod 10 as the central axis.

[0032] A push rod 12 is slidably connected inside the stirring blade 11. One end of the push rod 12 contacts a push block 13. An insert rod 14 is connected to the outer surface of the push block 13. The end of the insert rod 14 away from the push block 13 contacts a limit rod 15. The stirring blade 11 can push the push rod 12 to move. The movement of the push rod 12 can push the push block 13 out of the stirring blade 11. When the push block 13 moves, it will move the insert rod 14 with it. When the push block 13 is pushed out of the stirring blade 11 by the push rod 12, the insert rod 14 will push the limit rod 15 out of the positioning block 7.

[0033] A motor 16 is mounted on the upper surface of the top cover 2. The output end of the motor 16 is connected to the upper surface of the rotating rod 4. The top cover 2 restricts the position of the motor 16 so that the motor 16 will not rotate on its own when it starts. The start of the motor 16 will cause the rotating rod 4 to rotate.

[0034] The outer surface of the rotating rod 4 is rotatably connected to the inside of the top cover 2, and the outer surface of the rotating rod 4 is rotatably connected to the inside of the tank 1. The top cover 2 and the tank 1 will reduce the vibration generated when the rotating rod 4 rotates.

[0035] A baffle block 17 is connected to the outer surface of the push rod 12. The outer surface of the baffle block 17 is slidably connected to the inside of the stirring blade 11. The user can move the push rod 12 by moving the baffle block 17.

[0036] The outer surface of the push block 13 is slidably connected to the interior of the stirring blade 11, and the outer surface of the push block 13 is slidably connected to the interior of the mounting block 9. When the push block 13 moves between the stirring blade 11 and the mounting block 9, it prevents the stirring blade 11 from rotating around the positioning rod 10.

[0037] The outer surface of the insertion rod 14 is slidably connected to the interior of the mounting block 9, and the outer surface of the insertion rod 14 is slidably connected to the interior of the positioning block 7. The mounting block 9 and the positioning block 7 restrict the direction in which the insertion rod 14 can move.

[0038] The outer surface of the limiting rod 15 is slidably connected to the inside of the positioning block 7, and the outer surface of the limiting rod 15 is slidably connected to the inside of the positioning ring 5. When the limiting rod 15 moves between the positioning block 7 and the positioning ring 5, the positioning block 7 cannot rotate around the threaded rod 6. One end of the limiting rod 15 inside the positioning ring 5 is connected to an elastic component, which provides thrust to the limiting rod 15.

[0039] The mounting block 9 has an internal connection to a spring 18. One end of the spring 18 is connected to the outer surface of the push block 13. The spring 18 is fitted onto the outer surface of the insert rod 14. The spring 18 provides a thrust to the mounting block 9. The insert rod 14 can prevent the spring 18 from bulging to one side when compressed.

[0040] Working principle: When placing the rotating rod 4 and the stirring blade 11 into the tank 1, the operator can first push the blocking block 17. The movement of the blocking block 17 will cause the push rod 12 to push the push block 13 out of the stirring blade 11. The movement of the push block 13 will cause the insert rod 14 to push the limit rod 15 out of the positioning block 7. Then the user can rotate the positioning block 7 until the stirring blade 11 can rotate downwards. Then rotate the stirring blade 11 so that the stirring blade 11 is parallel to the rotating rod 4, and then the rotating rod 4 and the stirring blade 11 can be placed into the tank 1. Then the push block 13 and the limit rod 15 can be reinserted into their original positions. When the stirring blade 11 is damaged, the user can rotate the protective block 8 to remove the protective block 8 from the threaded rod 6. Then the user can remove the positioning block 7 and replace it with a new one.
