Description

Technical Field

[0001] This utility model relates to the field of coating spraying technology, and in particular to a spraying equipment for the production of a new polyurea material. Background Technology

[0002] In modern industrial production and construction, polyurea materials are increasingly widely used due to their superior waterproof, corrosion-resistant, and wear-resistant properties. To ensure that polyurea materials can fully utilize their excellent characteristics, high-quality production and spraying equipment is crucial. Polyurea production and spraying equipment can uniformly and efficiently spray polyurea materials onto various object surfaces, meeting the needs for protective coatings in different scenarios, and playing an irreplaceable role in ensuring project quality and extending the service life of objects.

[0003] Traditional polyurea material production spraying equipment mostly employs relatively simple mechanical structures in the mixing stage. Commonly, a single motor drives a mixing shaft with ordinary-shaped mixing blades. The technical principle is that the motor drives the mixing shaft to rotate, causing the mixing blades to rotate and thus mixing the polyurea material, ensuring the various raw materials are evenly mixed.

[0004] Because there is only one stirring shaft, the coverage area of ​​the blades is limited, and a large area within the storage tank cannot be effectively reached by the blades. Materials farther from the stirring shaft cannot participate in mixing as frequently as those closer to the shaft, resulting in significant differences in the degree of mixing at different locations. This uneven mixing prevents the polyurea components from fully blending, affecting the uniformity of material properties. Therefore, a new polyurea material production spraying device is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a polyurea new material production spraying equipment, which aims to improve the problem that the traditional polyurea material stirring in the prior art uses single-shaft stirring, which has a limited stirring range and is not uniform enough.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A new polyurea material production spraying equipment includes a base plate, a storage box fixedly connected to the side wall of the base plate, a fixed frame fixedly connected to the side wall of the storage box, a stirring assembly disposed inside the storage box, a mixer fixedly connected to the side wall of the fixed frame, a controller fixedly connected to the side wall of the fixed frame, a spray gun disposed on the side wall of the storage box, and a fixed assembly disposed inside the spray gun.

[0008] The stirring assembly includes a rotating shaft and stirring blades. A main gear is rotatably connected to the side wall of the storage tank, and a driven gear is rotatably connected to the side wall of the storage tank. A motor is installed inside the fixed frame. A partition is fixedly connected inside the storage tank. A connecting frame is fixedly connected inside the storage tank. A main gear is rotatably connected inside the connecting frame. The rotating shaft is rotatably connected inside the connecting frame. A driven gear is fixedly connected to the side wall of the rotating shaft. The stirring blades are fixedly connected to the side wall of the rotating shaft.

[0009] As a further description of the above technical solution:

[0010] The fixing component includes a locking block, and a delivery pipe is fixedly connected to the side wall of the spray gun, and the side wall of the delivery pipe is fixedly connected to the side wall of the mixer.

[0011] As a further description of the above technical solution:

[0012] A sliding frame is fixedly connected to the side wall of the spray gun, and a spray head is slidably connected inside the sliding frame;

[0013] As a further description of the above technical solution:

[0014] The nozzle has a fixing hole inside, and a sleeve is fixedly connected inside the sliding frame.

[0015] As a further description of the above technical solution:

[0016] The locking block is slidably connected to the sleeve and the fixing hole, and a connecting block is fixedly connected to the side wall of the locking block;

[0017] As a further description of the above technical solution:

[0018] A spring is fixedly connected to the side wall of the connecting block, and the spring side wall is fixedly connected to the inside of the sleeve.

[0019] As a further description of the above technical solution:

[0020] The first main gear meshes with the first driven gear, and the output end of the motor is connected to the first main gear;

[0021] As a further description of the above technical solution:

[0022] The second main gear is connected to the first driven gear, and the second main gear meshes with the second driven gear. The second driven gear is rotatably connected inside the connecting frame, and the stirring blade has a recessed hole inside.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the starting motor drives the main gear one to rotate, the main gear one meshes with the driven gear one, and drives the driven gears one on both sides to rotate. The storage box is divided into two by a partition. The driven gear one drives the main gear two to rotate, the main gear two meshes with the driven gear two, and causes the driven gears two on both sides to rotate, thereby driving the rotating shaft and stirring blade to rotate, stirring the material in the storage box. The concave hole in the stirring blade increases the material flowability, which solves the problem that the traditional polyurea material stirring uses single-shaft stirring, which has a limited stirring range and is not uniform enough. The above technical solution improves the uniformity and efficiency of polyurea material stirring.

[0025] 2. In this utility model, when the nozzle of the spray gun needs to be replaced or cleaned, the nozzle is pulled and moved within the sliding groove frame, causing the locking block to be squeezed into the sleeve. The connecting block compresses the spring, and the locking block disengages from the fixing hole. After the nozzle is removed from the fixing hole, it can be taken out. This solves the problem of disassembly and installation requiring tools when fastened with bolts and nuts. The above technical solution improves the convenience and efficiency of nozzle replacement and cleaning. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a polyurea new material production spraying equipment, including a base plate 1, a storage tank 2 fixedly connected to the side wall of the base plate 1, a fixing frame 3 fixedly connected to the side wall of the storage tank 2, a stirring assembly disposed inside the storage tank 2, a mixer 4 fixedly connected to the side wall of the fixing frame 3, a controller 5 fixedly connected to the side wall of the fixing frame 3, a spray gun 7 disposed on the side wall of the storage tank 2, and a fixing assembly disposed inside the spray gun 7; the stirring assembly includes a rotating shaft 14 and a stirring blade 16; a main gear 9 rotatably connected to the side wall of the storage tank 2, a driven gear 10 rotatably connected to the side wall of the storage tank 2, a motor 11 disposed inside the fixing frame 3, a partition 8 fixedly connected inside the storage tank 2, and a... There is a connecting frame 12, and a main gear 13 is rotatably connected inside the connecting frame 12. A rotating shaft 14 is rotatably connected inside the connecting frame 12. A driven gear 15 is fixedly connected to the side wall of the rotating shaft 14. A stirring blade 16 is fixedly connected to the side wall of the rotating shaft 14. A main gear 9 meshes with a driven gear 10. The output end of the motor 11 is connected to the main gear 9. A main gear 13 is connected to a driven gear 10. A main gear 13 meshes with a driven gear 15. A driven gear 15 is rotatably connected inside the connecting frame 12. A recess 17 is provided inside the stirring blade 16. The stirring blade 16 is used to stir the material in the storage tank 2. The recess 17 inside the stirring blade 16 is used to increase the fluidity of the material during stirring.

[0035] When using this equipment, start motor 11. Motor 11 serves as the power source, providing power to the entire mixing assembly. Motor 11 drives the main gear 9 to rotate, and the main gear 9 meshes with the driven gear 10, thereby driving the driven gears 10 on both sides to rotate through transmission. The internal space of storage tank 2 is divided into two by partition 8. This is to store the A component and R component raw materials required for polyurea spraying separately, preventing the two components from reacting before mixing and ensuring the stability of the raw material performance.

[0036] The driven gear 10 connects to the main gear 13 and rotates it. The main gear 13 meshes with the driven gear 15, causing the driven gears 15 on both sides to rotate, which in turn drives the rotating shaft 14 to rotate, causing the stirring blade 16 to rotate accordingly. The function of the stirring blade 16 is to stir the material in the storage tank 2, preventing sedimentation or stratification and ensuring the uniformity of the material to guarantee the subsequent spraying effect. The concave holes 17 inside the stirring blade 16 can increase the fluidity of the material during stirring, allowing the material to mix better. The stirred material is conveyed to the mixer 4 through corresponding channels for mixing. The mixer 4 can fully mix the A and R components to achieve the required properties of the polyurea material. Finally, it is sprayed out through the spray gun 7, which is the tool for spraying the mixed polyurea material onto the surface of the target object.

[0037] Reference Figure 2 , Figure 4 and Figure 5 The fixing components include a locking block 22, a conveying pipe 6 fixedly connected to the side wall of the spray gun 7, the side wall of the conveying pipe 6 fixedly connected to the side wall of the mixer 4, a sliding frame 18 fixedly connected to the side wall of the spray gun 7, a nozzle 19 slidably connected inside the sliding frame 18, a fixing hole 20 opened inside the nozzle 19, the fixing hole 20 and the locking block 22 are used to cooperate with each other to fix the nozzle 19, a sleeve 21 fixedly connected inside the sliding frame 18, the locking block 22 slidably connected inside the sleeve 21 and the fixing hole 20, a connecting block 23 fixedly connected to the side wall of the locking block 22, a spring 24 fixedly connected to the side wall of the connecting block 23, the spring 24 is used for rebound reset, and the side wall of the spring 24 is fixedly connected inside the sleeve 21.

[0038] When the nozzle 19 of the spray gun 7 needs to be replaced or cleaned, the nozzle 19 is the component that determines the spraying effect and quality. Different nozzles 19 can achieve different spraying shapes and ranges. By pulling the nozzle 19, it is moved inside the slide frame 18, which provides guidance and support for the nozzle 19. The movement of the nozzle 19 compresses the locking block 22, which serves to fix the nozzle 19. The locking block 22 enters the sleeve 21, causing the connecting block 23 to compress the spring 24. The sleeve 21 provides space for the movement of the locking block 22, and the spring 24 is used to store and release elastic potential energy. As the locking block 22 disengages from the fixing hole 20, the fixing hole 20 and the locking block 22 cooperate to fix the nozzle 19. The fixing of the nozzle 19 is then released, and it can be removed for replacement or cleaning.

[0039] Working principle: When using the equipment, the starter motor 11 drives the main gear 9 to rotate. The main gear 9 meshes with the driven gear 10, thereby driving the driven gears 10 on both sides to rotate. The internal space of the storage tank 2 is divided into two by the partition 8. The driven gear 10 is connected to the main gear 13 and makes it rotate. The main gear 13 meshes with the driven gear 15, causing the driven gears 15 on both sides to rotate, which in turn drives the rotating shaft 14 to rotate, causing the stirring blade 16 to rotate and stir the material in the storage tank 2. The concave hole 17 inside the stirring blade 16 can increase the fluidity of the material during stirring. The stirred material is transported to the mixer 4 through the corresponding channel for mixing, and finally sprayed out through the spray gun 7.

[0040] When it is necessary to replace or clean the nozzle 19 of the spray gun 7, the nozzle 19 is pulled to move it inside the slide frame 18. The movement of the nozzle 19 causes the locking block 22 to be squeezed and enter the sleeve 21, causing the connecting block 23 to squeeze the spring 24. As the locking block 22 disengages from the fixing hole 20, the fixing of the nozzle 19 is released, and it can be taken out for replacement or cleaning.

[0041] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
