[0002] Waterproof membranes are mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater seepage. They are flexible building materials that can be rolled up and serve as a leak-proof connection between the foundation and the building. They are the first line of defense for waterproofing the entire project and play a vital role in the overall project.

[0003] The production of waterproof membrane requires coating mixing. To improve mixing efficiency, a graded mixing device is often used. During the mixing process, due to the weight of the materials, the materials at the bottom of the mixing device will accumulate, and some materials will clump together, resulting in uneven mixing, reduced coating quality, and affected waterproof membrane performance.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0020] Please see Figure 1-7 A coating grading and mixing device for waterproof membrane production includes a housing 1, with an inlet 11 and an outlet 12. A stirring mechanism and a telescopic mechanism are respectively installed inside the housing 1. The telescopic mechanism drives the stirring mechanism to perform a linear reciprocating motion within the housing 1 to fully stir the materials inside. Through the telescopic mechanism, the stirring mechanism can stir the materials located at the bottom of the housing 1, preventing caking. Furthermore, the reciprocating motion of the stirring mechanism ensures thorough mixing of the materials within the housing 1, enhancing the uniformity of the mixture and improving the processing quality.

[0021] In a further embodiment of this utility model, the stirring mechanism includes a motor 2 fixedly mounted on the upper side of the housing 1. A bushing 21 is fixedly connected to the output shaft of the motor 2. The bushing 21 is rotatably connected to the housing 1. A rotating shaft 22 is slidably connected within the bushing 21 in the axial direction. When the bushing 21 rotates, it drives the rotating shaft 22 to rotate synchronously. The rotating shaft 22 is provided with multiple blades 23. Multiple flat keys 24 are also provided on the rotating shaft 22. A sliding groove 25, adapted to each flat key 24, is provided within the bushing 21. The motor 2 drives the rotating shaft 22 to rotate through the cooperation of the flat keys 24 on the rotating shaft 22 and the sliding grooves 25 on the bushing 21, thereby stirring the material through the blades 23. The flat keys 24 and the sliding grooves 25 are slidably connected, allowing the rotating shaft 22 to move along the axial direction of the bushing 21.

[0022] In a further embodiment of this utility model, the telescopic mechanism includes a turntable 3 rotatably connected to a bushing 21. A limiting groove 31, connecting the beginning and end of the turntable 3, is provided on the outer surface of its sidewall. An L-rod 32 is slidably connected to the upper side of the housing 1. One end of the L-rod 32 is fixedly connected to a limiting rod 33 adapted to the limiting groove 31. The limiting rod 33 extends into and slidably connects to the limiting groove 31, and the other end of the L-rod 32 is rotatably connected to a rotating shaft 22. The limiting groove 31 includes an inclined groove 37 and a horizontal groove 34. The two ends of the inclined groove 37 and the horizontal groove 34 are connected to form a closed groove connecting the beginning and end. The horizontal groove 34 is positioned at a lower height than the inclined groove 37.

[0023] See appendix Figure 2 Rotating turntable 3 causes the limiting groove on turntable 3 to rotate synchronously. Since the limiting rod 33 on L rod 32 extends into and slides into the limiting groove 31, when the limiting rod 33 slides with the inclined groove 37, the height of the inclined groove 37 in the vertical direction changes continuously. The L rod 32 is slidably connected to the housing 1 and is limited. The limiting rod 33 drives the L rod 32 to move up and down, and the movement of the L rod 32 drives the rotating shaft 22 to move. When the limiting rod 33 slides with the horizontal groove 34, the limiting rod 33 and the L rod 32 remain at their respective heights, thereby keeping the rotating shaft 22 at that height, thus stirring the material at the bottom of the housing 1. This causes the rotating shaft 22 to form a cyclical motion of rising, falling, and maintaining a horizontal position, thereby effectively stirring the material inside the housing 1.

[0024] It is worth noting that, see appendix Figure 6 and attached Figure 7A ring 38 is fixedly connected to one end of the L-rod 32 that is connected to the rotating shaft 22. A groove is provided on the rotating shaft 22. The ring 38 is rotatably connected to the rotating shaft 22 at the groove, that is, the L-rod 32 and the rotating shaft 22 are rotatably connected. The cooperation between the ring 38 and the groove makes the L-rod 32 and the rotating shaft 22 form a snap-fit ​​connection in the vertical direction, so that the up and down movement of the L-rod 32 can drive the up and down movement of the rotating shaft 22.

[0025] In a further embodiment of this utility model, a reduction mechanism is also included. The reduction mechanism includes a drive gear 4 fixedly connected to a bushing 21. A reduction assembly is drivenly connected to the drive gear 4. The reduction assembly includes a first reduction gear 41 and a second reduction gear 42 meshing with each other. The drive gear 4 meshes with the first reduction gear 41. The first reduction gear 41 and the second reduction gear 42 are respectively fixedly connected to a first reduction shaft 43 and a second reduction shaft 44. The first reduction shaft 43 and the second reduction shaft 44 are respectively rotatably connected to the housing 1, and the second reduction shaft 44 drives the turntable 3 to move through a transmission mechanism. The transmission mechanism includes a transmission gear 45 fixedly mounted on the second reduction shaft 44. A gear ring 35 meshing with the transmission gear 45 is provided on the inner wall of the turntable 3. The reduction mechanism is driven by a motor 2, and the speed is reduced by the reduction assembly to drive the turntable 3 to rotate. Specifically, the motor 2 drives the drive gear 4 to rotate through the bushing 21. The rotation of the drive gear 4 drives the second reduction shaft 44 to rotate through the meshing of the first reduction gear 41 and the second reduction gear 42. The rotation of the second reduction shaft 44 causes the turntable 3 to rotate through the meshing of the transmission gear 45 and the gear.

[0026] In a further embodiment of this utility model, the bottom of the turntable 3 is provided with multiple through holes 36. The turntable 3 receives the material from the feed inlet 11 and transmits it to the stirring mechanism inside the housing 1 through the through holes 36. The material enters the turntable 3 through the feed inlet 11, undergoes centrifugal motion in the rotating turntable 3, and enters the stirring mechanism inside the housing 1 through the through holes 36 for stirring. Compared with the material directly entering the stirring mechanism, the turntable 3 throws the material towards the inner wall of the housing 1, so that the material is evenly transported into the stirring mechanism, thereby improving the mixing effect.

[0027] Working principle: The material enters the turntable 3 through the feed port 11, undergoes centrifugal motion in the rotating turntable 3, and enters the stirring mechanism inside the casing 1 through the through hole 36 for stirring. After stirring is completed, the valve of the discharge port 12 is opened to discharge the mixed material.

[0028] Motor 2 drives drive gear 4 to rotate via bushing 21. Drive gear 4 rotates and drives second reduction shaft 44 to rotate via meshing first reduction gear 41 and second reduction gear 42. Second reduction shaft 44 rotates and meshes with transmission gear 45 to make turntable 3 rotate. Turntable 3 rotates and, through the engagement of limiting groove 31 on turntable 3 and limiting rod 33 on L rod 32, makes rotating shaft 22 form a cyclical motion of rising, falling and maintaining horizontal position (for the sake of brevity, please refer to the above for the specific motion process). In addition, while driving turntable 3, motor 2 also drives rotating shaft 22 to rotate through the engagement of flat key 24 on rotating shaft 22 and sliding groove 25 on bushing 21. This allows the material to be stirred by blades 23. Flat key 24 and sliding groove 25 are slidably connected so that rotating shaft 22 can move along the axial direction of bushing 21.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
