Description

Technical Field

[0001] The utility model relates to the technical field of waterproof coiled material production, in particular to a sand spraying device for a waterproof coiled material production process. Background Art

[0002] The production process of waterproof coiled materials is unrolling, dipping, sand spraying, film laminating, cooling, and winding. The coiled base fabric is unrolled, asphalt is dipped on the unrolled base fabric, a layer of sand is sprayed on the base fabric dipped with asphalt, then a side PE film is laminated on the sand-sprayed base fabric, the laminated waterproof coiled material is cooled, and finally the cooled waterproof coiled material is wound into rolls. By spraying a layer of sand on the base fabric dipped with asphalt, the wear resistance of the waterproof coiled material can be improved and the waterproof effect can be enhanced.

[0003] However, after spraying sand on the base fabric dipped with asphalt, the sand will adhere to the base fabric under the action of asphalt. Since the sand is simply sprayed on the base fabric dipped with asphalt, the adhesion effect on the base fabric will be slightly poor, resulting in poor density of the sand material on the base fabric. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a sand spraying device for a waterproof coiled material production process to solve the above-mentioned existing problems.

[0005] To achieve the above purpose, the utility model provides a sand spraying device for a waterproof coiled material production process, including a conveyor belt and a rolling component;

[0006] A sand spraying box is arranged on the upper side of the front end of the conveyor belt. An outlet is arranged at the lower end of the sand spraying box, and a rotatable sand spraying roller is arranged at the position of the outlet;

[0007] The rolling component is arranged on the upper side of the rear end of the conveyor belt. The rolling component includes a driving part, fixing plates, guiding blocks, U-shaped sliding blocks, and a rolling roller. There are two fixing plates, and the two fixing plates are respectively arranged on both sides of the conveyor belt. Guiding blocks are respectively arranged on the two fixing plates. There are two U-shaped sliding blocks, and the two U-shaped sliding blocks are respectively movably arranged on the guiding blocks. Both ends of the rolling roller are rotatably connected to the two U-shaped sliding blocks respectively, and the driving part is used to drive the U-shaped sliding blocks to reciprocate on the fixing blocks.

[0008] The above beneficial effects are as follows: The base fabric coated with asphalt is conveyed from front to back. When passing under the sand spraying box, the sand in the sand spraying box falls onto the sand spraying roller through the outlet, and then the sand is continuously sprayed onto the asphalt on the base fabric through the rotating sand spraying roller. Subsequently, the driving member drives the U-shaped sliding block to repeatedly move horizontally along the guiding block, and the U-shaped sliding block drives the rolling roller to continuously move. During the movement, the rolling roller rotates and continuously compresses the sand on the asphalt, making the sand adhere more firmly to the asphalt layer. At the same time, the compaction effect of the rolling roller improves the density of the sand material.

[0009] A preferred solution is that there are two groups of the driving members, and the two groups of driving members are respectively arranged on two fixed plates. Each group of driving members includes a rotating disk, a hinged rod, and a motor. The outer end of the upper side of the rotating disk is rotatably connected to the front end of the hinged rod, the rear end of the hinged rod is rotatably connected to the upper end of the U-shaped sliding block, and the output shaft of the motor passes through the fixed plate and is connected to the rotating disk.

Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0017] AsFigure 1 and Figure 2 As shown in Figure 2 , the utility model provides a sand - spreading device for a waterproof coiled material production process, which includes a conveyor belt 10 and a rolling component 20;

[0019] The rolling component 20 is arranged on the upper side of the rear end of the conveyor belt 10. The rolling component 20 includes a driving part 210, a fixing plate 21, a guiding block 22, a U - shaped sliding block 23 and a rolling roller 24. There are two fixing plates 21, and the two fixing plates 21 are respectively arranged on both sides of the conveyor belt 10. The guiding blocks 22 are respectively arranged on the two fixing plates 21. There are two U - shaped sliding blocks 23, and the two U - shaped sliding blocks 23 are respectively movably arranged on the guiding blocks 22. The two ends of the rolling roller 24 are respectively rotatably connected to the two U - shaped sliding blocks 23. The driving part 210 is used to drive the U - shaped sliding block to reciprocate on the fixed block.

[0020] During the working process, the base fabric impregnated with asphalt is conveyed from front to back. When passing under the sand - spreading box 11, the sand in the sand - spreading box 11 falls onto the sand - spreading roller 12 through the outlet, and then the sand is continuously spread on the asphalt on the base fabric through the rotating sand - spreading roller 12. Subsequently, the driving part 210 drives the U - shaped sliding block 23 to repeatedly move horizontally along the guiding block 22. The U - shaped sliding block 23 drives the rolling roller 24 to continuously move. The rolling roller 24 rotates during the moving process and continuously rolls the sand on the asphalt, so that the sand adheres more firmly to the asphalt layer, and at the same time, the compactness of the sand is improved through the compaction effect of the rolling roller 24.

[0021] Preferably, there are two groups of the driving parts 210, and the two groups of driving parts 210 are respectively arranged on the two fixing plates 21. Each group of the driving parts 210 includes a rotating disk 211, a hinged rod 212 and a motor 213. The outer end of the upper side of the rotating disk 211 is rotatably connected to the front end of the hinged rod 212, the rear end of the hinged rod 212 is rotatably connected to the upper end of the U - shaped sliding block 23, and the output shaft of the motor 213 passes through the fixing plate and is connected to the rotating disk.

[0022] The motor 213 drives the rotating disk 211 to rotate. The rotating disk 211 drives the hinged rod 212 to rotate. Since the hinged rod 212 is eccentrically connected to the rotating disk 211, at this time, the hinged rod 212 drives the U - shaped sliding block 23 to move horizontally, and the U - shaped sliding block 23 drives the rolling roller 24 to move horizontally, thus completing the rolling process.

[0023] Preferably, support rods 13 are respectively arranged on both sides of the sand spraying box 11. The lower ends of the support rods 13 are connected to the side plates 15 of the conveyor belt 10, and one end of the sand spraying roller 12 is connected to the driving motor 19.

[0024] Preferably, the two fixing plates 21 are respectively arranged in an adjustable manner, and the two lower ends of the fixing plates 21 are respectively connected to the telescopic rods of the lifting cylinders 51.

[0025] By the telescopic rod of the lifting cylinder 51 extending to drive the fixing plate 21 to rise, or the lifting cylinder 51 contracting to drive the fixing plate 21 to descend, the height position of the entire rolling assembly 20 can be adjusted, so that the height position of the rolling assembly can be adjusted according to the thickness of the asphalt applied on the base fabric.

[0026] Preferably, a collection box 81 is arranged on the lower side of the rear end of the conveyor belt 10.

[0027] In addition, during the process of conveying the base fabric after being dipped with asphalt and then sand-sprayed, it is inevitable that there will be sand residues on the conveyor belt 10. At this time, when the conveyor belt 10 rotates to the rear end, the sand on the conveyor belt 10 will fall into the collection box 81 for collection, preventing the sand from falling to the ground.

[0028] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
