The over-expanded polyurethane material may have problems such as too large pores and uneven density, which will affect its compressive strength and heat insulation performance.

[0015] The present invention provides a polyurethane insulation device for exterior wall insulation. It has the following beneficial effects: (1) For the polyurethane insulation device for exterior wall insulation, when the motor is started, the output end of the motor drives the reciprocating lead screw to rotate. The rotation of the reciprocating lead screw drives the sleeve box to reciprocate up and down, improving the efficiency of spraying polyurethane material by the spraying box. When the sliding rod slides away from the reciprocating lead screw, it drives the rotating rod to rotate counterclockwise. The rotation of the rotating rod drives the swing of the rotating shaft, and the spraying box swings upward under the action of the rotating shaft, realizing multi-angle spraying of the spraying box. Through spraying at different angles, the spraying is made more uniform, further improving the spraying efficiency, avoiding the problems of local over-thickness or over-thinness, thus enhancing the overall consistency of the insulation effect, and being able to cover more areas in a shorter time.

[0016] (2) For the polyurethane thermal insulation device used for external wall thermal insulation, when the staff pushes the trolley to move towards the construction wall, then the material feeding plate moves until the circular groove coincides with the port of the pipeline, and the polyurethane material inside the pipeline can pass through. It realizes that only when the protection plate is in full contact with the wall, the restriction on the pipeline will be released and the polyurethane material will be sprayed, preventing the premature start of the spraying of the polyurethane material by the staff's accidental touch operation, causing the sprayed material to overflow to places that do not require thermal insulation and being contaminated by the sprayed material, reducing the cleaning workload, ensuring the cleanliness of the construction site. When the sliding box reciprocates up and down, it drives the protection plate to move, so that the protection plate always maintains a consistent protection effect when the spraying box moves for spraying, realizing the control of spraying the polyurethane material, controlling the coverage area and spraying thickness of the sprayed material, and ensuring that the material is evenly and accurately sprayed onto the predetermined area.

[0017] (3) For the polyurethane thermal insulation device used for external wall thermal insulation, when the first inclined block moves upward, it drives the cutting plate to move. Then the cutting plate moves upward until it gets out of the restriction of the protection plate on it. Releasing the limit can adjust the position of the cutting plate more quickly, reducing unnecessary steps and improving the cutting speed. At the same time, it also prevents unnecessary negative impacts caused by improper operation of the staff. The free end of the telescopic clamping arm moves to drive the cutting plate to move until it reaches the designated position. Then when the sleeve box moves, it drives the cutting plate to move to cut and shape the over-expanded polyurethane material. The over-expanded polyurethane material may have problems such as too large pores and uneven density, which will affect its compressive strength and heat insulation performance. Cutting and adjusting it can remove the over-expanded part and retain the area with good performance. Description of the Drawings

A Z-shaped groove 58 is formed on the surface of the lifting frame 4, the sliding rod 59 is slidably installed on the inner wall of the Z-shaped groove 58, the P-shaped rod 510 is fixedly installed on the circumferential surface of the sliding rod 59, the clamping plate 511 is slidably installed on the surface of the lifting frame 4, the linkage rod 512 is rotatably connected to the end of the P-shaped rod 510 away from the clamping plate 511, the rotating rod 513 is fixedly installed on the circumferential surface of the end of the rotating shaft 55 away from the sliding box 54. The movement of the P-shaped rod 510 drives the rotating rod 513 to rotate clockwise, the rotation of the rotating rod 513 drives the rotating shaft 55 to swing, and the spraying box 56 swings downward under the action of the rotating shaft 55.

[0022] The surface of the lifting frame 4 is provided with a first sliding groove. The sleeve box 53 is fixedly connected to the sliding box 54. The sleeve box 53 is slidably connected to the lifting frame 4. The sleeve box 53 is threadedly connected to the reciprocating lead screw 52. The output end of the motor 51 drives the reciprocating lead screw 52 to rotate, and the rotation of the reciprocating lead screw 52 drives the sleeve box 53 to reciprocate up and down.

[0023] The shape of the clamping plate 511 is set to L-shaped. The clamping plate 511 is slidably connected to the P-shaped rod 510. The rotating rod 513 is rotatably connected to one end of the linkage rod 512 away from the P-shaped rod 510. The clamping plate 511 is fixedly connected to the sleeve box 53.

[0024] When this embodiment works: Start the feeding pump 3. The feeding pump 3 inputs the polyurethane material inside the material cylinder 2 into the sliding box 54 through the pipeline 61. Then the sliding box 54 transports the polyurethane material into the spraying box 56. At this time, the staff turns on the spray head 57, and the polyurethane material is sprayed onto the wall through the spray head 57. Then start the motor 51. The output end of the motor 51 drives the reciprocating lead screw 52 to rotate, and the rotation of the reciprocating lead screw 52 drives the sleeve box 53 to reciprocate up and down, improving the spraying efficiency of the polyurethane material in the spraying box 56. At the same time, the movement of the sleeve box 53 drives the clamping plate 511 to move. When the clamping plate 511, under the action of the sleeve box 53, reciprocates up and down to drive the sliding rod 59 to move, and at the same time the sliding rod 59 slides on the inner wall of the Z-shaped groove 58. At the same time, the movement of the sliding rod 59 drives the P-shaped rod 510 to move. The P-shaped rod 510 moves in the direction close to the reciprocating lead screw 52 to drive the linkage rod 512 to move. The movement of the linkage rod 512 drives the rotating rod 513 to rotate clockwise. The rotation of the rotating rod 513 drives the swing of the rotating shaft 55. The spraying box 56 swings downward under the action of the rotating shaft 55. When the sliding rod 59 slides in the direction away from the reciprocating lead screw 52, on the contrary, it drives the rotating rod 513 to rotate counterclockwise. The rotation of the rotating rod 513 drives the swing of the rotating shaft 55. The spraying box 56 swings upward under the action of the rotating shaft 55, realizing multi-angle spraying of the spraying box 56. Through spraying at different angles, the spraying is made more uniform, further improving the spraying efficiency, avoiding the problem of local over-thickness or under-thickness, thus improving the overall consistency of the heat preservation effect, and can cover more areas in a shorter time, reducing the complexity and time cost of manual operation. Through the angle spraying of the spray head 57, the construction efficiency and construction quality are improved.

[0025] Please refer to Figures 1-8, on the basis of the above embodiments, in another embodiment of the present invention, it includes a limiting device and a protection device. The limiting device includes a pipeline 61, a protection plate 62, a fixing rod 63, a limiting plate 64, a return plate 66 and a material passing plate 67. The pipeline 61 is fixedly communicated with the feeding pump 3. The protection plate 62 is slidably installed on the top of the sliding box 54. The fixing rod 63 is fixedly installed on the surface of the protection plate 62. The limiting plate 64 is fixedly installed on the top of the sliding box 54. The return plate 66 is fixedly installed on the surface of the limiting plate 64. The material passing plate 67 is fixedly installed at one end of the fixing rod 63 away from the protection plate 62. At the same time, the protection plate 62 moves towards the direction close to the telescopic spring rod 65 under the action of the wall, and the movement of the protection plate 62 drives the movement of the fixing rod 63.

[0026] A telescopic spring rod 65 is fixedly installed on the surface of the limiting plate 64. The protection plate 62 is fixedly installed at the free end of the telescopic spring rod 65. The fixing rod 63 slidably penetrates through the surface of the limiting plate 64. The pipeline 61 is fixedly communicated with the sliding box 54. When the fixing rod 63 moves to drive the material passing plate 67 to move towards the direction close to the pipeline 61, and then the material passing plate 67 moves until the circular groove coincides with the port of the pipeline 61.

[0027] A circular groove is formed on the surface of the material passing plate 67. The material passing plate 67 is slidably connected with the return plate 66. The material passing plate 67 moves until the circular groove coincides with the port of the pipeline 61, and the polyurethane material inside the pipeline 61 can pass through.

[0028] The protection device includes telescopic clamping arms 71, a cutting plate 72, a first inclined block 73, a second inclined block 74, a push rod 75, a first connecting rod 76, an auxiliary rod 77, a second connecting rod 78 and a sleeve rod 79. The telescopic clamping arms 71 are fixedly installed on the top of the sleeve box 53. The cutting plate 72 is fixedly installed at the free end of the telescopic clamping arms 71. The first inclined block 73 is fixedly installed at the bottom of the cutting plate 72. The second inclined block 74 is fixedly installed on the surface of the protection plate 62. The push rod 75 is fixedly installed on the surface of the protection plate 62. The first connecting rod 76 is fixedly installed on the circumferential surface of the push rod 75. The auxiliary rod 77 is rotatably installed at one end of the first connecting rod 76 away from the push rod 75. The second connecting rod 78 is rotatably connected to one end of the auxiliary rod 77 away from the first connecting rod 76. The sleeve rod 79 is fixedly installed on the surface of the free end of the telescopic clamping arms 71. When the protection plate 62 moves away from the wall, it will drive the movement of the push rod 75. At the same time, the movement of the push rod 75 drives the movement of the first connecting rod 76, and the movement of the first connecting rod 76 drives the auxiliary rod 77 to rotate counterclockwise.

[0029] The surface of the first inclined block 73 is set as a first inclined surface, and the surface of the second inclined block 74 is set as a second inclined surface. One end of the second connecting rod 78 away from the auxiliary rod 77 is fixedly connected to the circumferential surface of the sleeve rod 79. The rotation of the auxiliary rod 77 drives the second connecting rod 78 to move closer to the wall.

[0030] During the operation of this embodiment: When the staff pushes the trolley 1 to move towards the construction wall, the movement of the trolley 1 drives the movement of the protection plate 62. Subsequently, the protection plate 62 contacts and presses against the wall. At the same time, the protection plate 62 moves towards the telescopic spring rod 65 under the action of the wall. The movement of the protection plate 62 drives the movement of the fixed rod 63. When the fixed rod 63 moves, it drives the material passing plate 67 to move towards the pipeline 61. Subsequently, the material passing plate 67 moves until the circular groove coincides with the port of the pipeline 61, and the polyurethane material inside the pipeline 61 can pass through. It is realized that only when the protection plate 62 is in full contact with the wall, the restriction on the pipeline 61 will be released and the polyurethane material will be sprayed, preventing the premature start of the spraying of the polyurethane material by the spraying tank 56 due to the accidental touch operation of the staff, causing the sprayed material to overflow to places that do not need heat insulation and being contaminated by the sprayed material, reducing the cleaning workload, ensuring the cleanliness of the construction site. When the sliding box 54 reciprocates up and down, it drives the movement of the protection plate 62, so that the protection plate 62 always maintains the same protection effect when the spraying tank 56 moves to spray materials. The control of spraying the polyurethane material is realized, controlling the coverage area and spraying thickness of the sprayed material, ensuring that the material is sprayed evenly and precisely onto the predetermined area, and also ensuring that the sprayed material is concentrated and sprayed on the target area, avoiding the diffusion of the sprayed material to areas that do not need to be sprayed.

[0031] When the protection plate 62 moves away from the wall, it will drive the movement of the second inclined block 74. The movement of the second inclined block 74 contacts and presses against the first inclined block 73 to move upward. The upward movement of the first inclined block 73 drives the movement of the cutting plate 72. Subsequently, the cutting plate 72 moves upward until it breaks away from the restriction of the protection plate 62 on it. Removing the limit can adjust the position of the cutting plate 72 more quickly, reducing unnecessary steps and improving the cutting speed. At the same time, it also prevents unnecessary negative impacts caused by improper operation of the staff. At the same time, when the protection plate 62 moves away from the wall, it will drive the movement of the push rod 75. At the same time, the movement of the push rod 75 drives the movement of the first connecting rod 76. The movement of the first connecting rod 76 drives the auxiliary rod 77 to rotate counterclockwise. The rotation of the auxiliary rod 77 drives the second connecting rod 78 to move closer to the wall. The movement of the second connecting rod 78 drives the free end of the telescopic clamping arm 71 to move closer to the wall. The movement of the free end of the telescopic clamping arm 71 drives the movement of the cutting plate 72 until it reaches the designated position. Subsequently, when the sleeve box 53 moves, it drives the movement of the cutting plate 72 to cut and shape the over-expanded polyurethane material. The over-expanded polyurethane material may have problems such as too large pores and uneven density, which will affect its compressive strength and heat insulation performance. Cutting and adjusting it can remove the over-expanded part, retain the area with good performance, and remove the unevenly expanded part on the surface, making the surface of the thermal insulation material flat and smooth, meeting the construction requirements and ensuring the appearance quality of the building exterior wall.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
