Description

Technical Field

[0001] This utility model belongs to the field of polyurethane foaming technology, specifically a polyurethane spraying foaming device that is easy to clean. Background Technology

[0002] Polyurethane spray insulation material is an important branch of the polyurethane industry. Its key feature is its versatility, offering multiple functions including thermal insulation and waterproofing. Sprayed polyurethane includes two parts: direct spraying with primer and synthetic resin, and foamed polyurethane spraying. Direct spraying with primer and synthetic resin is mainly used for corrosion resistance, wear resistance, sealing, and thermal insulation. Its characteristics include good wear resistance, excellent erosion resistance, and a one-time coating without dripping. Before application, a foaming device is needed to foam the polyurethane spray material.

[0003] After use, existing foaming devices require cleaning. However, most existing foaming devices are one-piece designs, which makes cleaning them very complicated and difficult because they cannot be quickly disassembled. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a polyurethane spraying foaming device that is easy to clean. It solves the problem that most existing foaming devices are integrated units, which make cleaning the inside of the foaming device very complicated and difficult to disassemble quickly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polyurethane spraying foaming device that is easy to clean, comprising a foaming cylinder, a top cover being provided on the top of the foaming cylinder, a positioning post being fixedly connected to the bottom of the top cover, and a plurality of positioning posts being provided. Multiple positioning grooves are provided on the top of the foaming cylinder corresponding to the positions of the positioning posts, and the positioning posts are slidably connected through the positioning grooves. Insert blocks are fixedly connected to both sides of the top of the foaming cylinder, and mounting blocks are fixedly connected to both sides of the bottom of the top cover corresponding to the positions of the insert blocks. Insert rods are slidably connected through the mounting blocks, and handles are fixedly connected to the top of the insert rods. Limiting blocks are symmetrically fixedly connected to the bottom of the insert rods through the insert blocks. Limiting grooves are provided on the top of the insert blocks corresponding to the positions of the limiting blocks. A limiting ring is fixedly connected to the outer arc surface of the insert rods located on the top of the mounting blocks. A feed cylinder is fixedly connected to the top of the top cover, and a discharge pipe is fixedly connected to the bottom of the foaming cylinder.

[0006] As a further embodiment of this utility model: a motor protective shell is fixedly connected to the center of the top of the top cover, a servo motor is fixedly connected inside the motor protective shell, the output end of the servo motor passes through the top cover and is fixedly connected to a stirring rod, and the top end of the stirring rod is rotatably connected to the top cover through a bearing.

[0007] As a further embodiment of this utility model: the bottom of the foaming cylinder is fixedly connected to three fixed legs, and the bottom of the foaming cylinder is fixedly connected to a support leg on the side corresponding to the fixed legs.

[0008] As a further embodiment of this utility model: one end of the support leg is fixedly connected to the center of one side of the fixed leg, and the bottom sides of the fixed leg are rotatably connected to support arms via pins.

[0009] As a further embodiment of this utility model: one end of the support arm is rotatably connected to a connecting arm via a pin, and the bottom ends of the two connecting arms are rotatably mounted with movable wheels via pins.

[0010] As a further embodiment of this utility model: a damping telescopic rod is fixedly connected between the movable wheel and the fixed leg, and a buffer spring is sleeved on the outer arc surface of the damping telescopic rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This easy-to-clean polyurethane spraying foaming device features a rotating handle, a limiting block, an insert block, and a top cover. When it is necessary to disassemble the foaming cylinder and the top cover, the rotating handle drives the insert rod and the limiting block to rotate, aligning the limiting block with the limiting groove. At this point, the top cover can be lifted, and the top cover simultaneously pulls the insert rod out of the insert block, allowing the foaming cylinder and the top cover to be disassembled. This facilitates the cleaning of the inner wall of the foaming cylinder and the stirring rod, enabling quick disassembly and timely cleaning of the foaming device.

[0013] 2. This easy-to-clean polyurethane spraying foaming device, equipped with moving wheels, buffer springs, and damping telescopic rods, allows for easy movement on the construction site. When encountering bumpy roads, the moving wheels move up and down, compressing the buffer springs and damping telescopic rods. The spring force cushions the compression of the moving wheels, preventing violent vibrations that could damage the internal components of the foaming device and thus extending its lifespan.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a polyurethane spraying foaming device that is easy to clean, including a foaming cylinder 1, a top cover 2 provided on the top of the foaming cylinder 1, and a positioning post 3 fixedly connected to the bottom of the top cover 2. The number of positioning posts 3 is several. A plurality of positioning grooves 4 are opened on the top of the foaming cylinder 1 corresponding to the positions of the positioning posts 3. The positioning posts 3 are slidably connected in the positioning grooves 4. By setting the positioning posts 3 and the positioning grooves 4, when it is necessary to install the top cover 2 and the foaming cylinder 1, the positioning posts 3 at the bottom of the top cover 2 can be aligned with the positioning grooves 4 at the top of the foaming cylinder 1, and the positioning posts 3 can be inserted into the positioning grooves 4 to position the top cover 2 and prevent deviation when the top cover 2 is fixed.

[0021] The top two sides of the foaming cylinder 1 are fixedly connected with insert blocks 5. The bottom two sides of the top cover 2 are fixedly connected with mounting blocks 7 corresponding to the positions of the insert blocks 5. The mounting blocks 7 are slidably connected with insert rods 10. The top of the insert rods 10 is fixedly connected with handles 8. The bottom of the insert rods 10 passes through the insert blocks 5 and is symmetrically fixedly connected with limiting blocks 11. The top of the insert blocks 5 is provided with limiting grooves 6 corresponding to the positions of the limiting blocks 11. With the setting of the limiting grooves 6, when the limiting blocks 11 are aligned with the limiting grooves 6, the limiting blocks 11 and the insert rods 10 can be inserted into the limiting grooves 6 at the same time. When there is a certain angular deviation between the limiting blocks 11 and the limiting grooves 6, the top cover 2 and the foaming cylinder 1 are locked together.

[0022] The insertion rod 10 is fixedly connected to the outer arc surface at the top of the mounting block 7 with a limit ring 9. The top of the top cover 2 is fixedly connected with a feed cylinder 12, and the bottom of the foaming cylinder 1 is fixedly connected with a discharge pipe 13. With the setting of the feed cylinder 12, when it is necessary to fill, the filler can be filled through the feed cylinder 12 without opening the top cover 2, which is convenient for operation.

[0023] A motor protective shell 14 is fixedly connected to the center of the top of the top cover 2. A servo motor 15 is fixedly connected inside the motor protective shell 14. The output end of the servo motor 15 passes through the top cover 2 and is fixedly connected to a stirring rod 16. The top end of the stirring rod 16 is rotatably connected to the top cover 2 through a bearing. By setting the servo motor 15 and the stirring rod 16, the stirring rod 16 is rotated by starting the servo motor 15. The stirring rod 16 is used to stir the material in the foaming cylinder 1, thereby stirring and mixing the material in the foaming cylinder 1.

[0024] The bottom of the foaming cylinder 1 is fixedly connected to three fixed legs 18. The bottom of the foaming cylinder 1 is fixedly connected to one side of the fixed legs 18, and one end of the support leg 17 is fixedly connected to the center of one side of the fixed leg 18. The bottom sides of the fixed leg 18 are rotatably connected to the support arm 19 through the pin. By setting the support leg 17, the fixed leg 18 is supported by the support leg 17, so that the support leg 17 distributes the pressure on the fixed leg 18, thereby preventing all the pressure from acting on the fixed leg 18.

[0025] One end of the support arm 19 is rotatably connected to the connecting arm 20 via a pin. The bottom ends of the two connecting arms 20 are rotatably mounted with movable wheels 23 via pins. A damping telescopic rod 21 is fixedly connected between the movable wheel 23 and the fixed leg 18. A buffer spring 22 is sleeved on the outer arc surface of the damping telescopic rod 21. With the setting of the damping telescopic rod 21, when the buffer spring 22 is compressed and buffered, the damping telescopic rod 21 extends and retracts at the same time. The extension and retraction friction of the damping telescopic rod 21 reduces the rebound potential energy of the buffer spring 22 and prevents the buffer spring 22 from always being in a rebound state.

[0026] The working principle of this utility model is as follows: First, clean the inside of the foaming cylinder 1. After cleaning, the top cover 2 can be placed on top of the foaming cylinder 1. Align and insert the positioning post 3 at the bottom of the top cover 2 with the positioning groove 4 at the top of the foaming cylinder 1 to position the top cover 2. After positioning, press the handle 8 to drive the insertion rod 10 and the limiting block 11 to insert into the through block 5. At this time, the handle 8 can be rotated, which drives the insertion rod 10 and the limiting block 11 to rotate, causing the limiting block 11 and the limiting groove 6 to be misaligned, so that the limiting block 11 and the through block 5 are locked together, thereby installing and fixing the top cover 2. At this time, it can be moved. When the foaming cylinder 1 moves and encounters a bumpy road surface, the moving wheel 23 will squeeze the damping telescopic rod 21 and the buffer spring 22. The spring force of the buffer spring 22 will buffer and reduce shock. At the same time, the connecting arm 20 and the support arm 19 will rotate alternately and be supported by the connecting arm 20 and the support arm 19. At this time, the foaming cylinder 1 can be moved to a suitable position. Then, material is added into the feeding cylinder 12 so that the material enters the foaming cylinder 1. Then, the servo motor 15 is started, and the stirring rod 16 is driven by the servo motor 15 to stir and mix the material in the foaming cylinder 1, so that the material can foam.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
