Description

Technical Field

[0001] This invention relates to the field of mixing device technology, specifically to a mixing device for JS polymer cement-based waterproof coating. Background Technology

[0002] Polymer cement waterproof coating, abbreviated as JS waterproof coating, where J stands for polymer and S stands for cement, is an organic liquid coating composed of polymer emulsions such as polyacrylate emulsion and ethylene-vinyl acetate copolymer emulsion, along with various additives.

[0003] Existing patent (publication number: CN108211906A) discloses a mixing device for JS polymer cement-based waterproof coatings. This invention relates to a mixing device, specifically a mixing device for JS polymer cement-based waterproof coatings, including a support frame and a motor mounted on the top of the support frame. The motor's shaft is connected to a connecting shaft located at the top of the support frame, and a mixing shaft is fixed on the connecting shaft. A mixing roller is mounted on the mixing shaft. A cylinder is connected to the support frame via a fixed seat, and the outer wall of the cylinder is fixed by a locking buckle. The cylinder and the fixed seat are rotatably connected. A material outlet is located at the bottom of the cylinder, and the material outlet is connected to the inlet of a three-way valve. An inner liner is installed inside the cylinder, and a connecting pipe is connected to the top of the inner liner. A fine sieve is located at the outlet of the connecting pipe, and one end of the connecting pipe is connected to a suction pump fixed on the support frame. The combined use of the suction pump and the fine sieve enables the circulating crushing of the coating. This invention can completely refine the slurry, thoroughly solve the problem of small lumps, and simultaneously achieve thorough mixing of powder, thereby ensuring the accuracy of the proportions.

[0004] The above case addressed the issue of accurate proportions, but if the material is left for an extended period, its tendency to absorb water leads to clumping. This results in the outside being covered in water while the inside remains dry, causing uneven mixing. Furthermore, even if the clumps are broken up during internal mixing, the clumped material can damage the mixing blades, rendering the mixture impractical.

[0005] To address this, a JS polymer cement-based waterproof coating mixing device is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a JS polymer cement-based waterproof coating mixing device that can crush materials that have clumped inside the shell, thus avoiding insufficient mixing caused by material clumping. At the same time, this avoids mechanical wear and tear on the mixing device itself when directly mixing clumps, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a JS polymer cement-based waterproof coating mixing device, comprising a shell, a motor fixedly connected to the upper end of the shell, a feed pipe fixedly connected to the upper end of the shell near the left side, a discharge pipe fixedly connected to the lower end of the shell near the left side, a support leg fixedly connected to the lower end of the shell, a water pipe fixedly connected to the left side of the shell, a rotating rod fixedly connected to the lower end of the motor, a crushing mechanism provided on the left side of the rotating rod near the upper end, and a mixing mechanism provided at the center of the rotating rod.

[0008] The materials to be mixed are fed into the interior of the shell through the feed pipe, and an appropriate amount of water is introduced through the water pipe. At this time, the motor works, driving the rotating rod to rotate and the mixing mechanism to work. The mixing mechanism can move up and down to mix, which can avoid the material from separating and the phenomenon of uneven mixing when mixing horizontally. At the same time, the crushing mechanism can crush the lumps of material entering the shell, which can prevent the material from clumping and causing insufficient mixing. This also avoids the mechanical wear and tear of the mixing device when directly mixing lumps.

[0009] Preferably, the crushing mechanism includes a support rod, a pressure rod, a filter screen, a fixing block, a vertical rod, a horizontal rod, a striking block, a protrusion, and a support plate. The support rod is movably connected to the left side of the rotating rod's wall. The pressure rod is rotatably connected to the support rod's wall. The filter screen is fixedly connected to the inner wall of the outer casing near the upper end. The fixing block is fixedly connected to the center of the filter screen. The vertical rod is fixedly connected to the lower end of the fixing block near both sides. The horizontal rod is rotatably connected to the lower end of the vertical rod. The striking block is fixedly connected to the side of the horizontal rod away from the rotating rod. The support plate is fixedly connected to the center of both sides of the rotating rod's wall. The protrusion is fixedly connected to the upper end of the support plate.

[0010] When the rotating rod rotates, it drives the support rod to move, which in turn drives the pressure rod to move. The pressure rod then compresses the incoming material. The rotation of the rotating rod also drives the support plate to rotate, which in turn drives the protrusion to rotate. As the protrusion moves and squeezes against the crossbar, it causes the crossbar to rotate upwards. This rotation of the crossbar causes the striking block to rotate upwards, thus creating an impact with the filter screen. This accelerates the material's passage through the filter screen and its entry into the lower part of the outer casing. It should be noted that because the vertical rod is fixedly connected to the fixed block, the rotation of the crossbar causes the striking block to rotate. To ensure better contact between the striking block and the filter screen, the striking block is rotatably connected to the crossbar. This crushes any clumps of material and speeds up the mixing process.

[0011] Preferably, a groove is provided on the left side of the rotating rod wall, and a slider is slidably connected inside the groove. The left side of the slider is fixedly connected to the right side of the support rod, and a first spring is fixedly connected to the upper end of the slider.

[0012] Because the size of the clumps is uneven, when the clumps come into contact with the pressure rod, the pressure rod drives the support rod to move upward. The support rod then drives the slider to move inside the groove, while simultaneously squeezing the first spring. This prevents the clumps from being too hard and damaging the device.

[0013] Preferably, the fixed block is rotatably connected to a first damping bearing, the inside of the first damping bearing is fixedly connected to the rod wall of the rotating rod, and the filter screen is fixedly connected to a first bearing on the outside.

[0014] Because the feed pipe is located on the upper left side of the outer casing, the material will accumulate on one side when it enters the casing. When the rotating rod rotates, it drives the first damping bearing to rotate, which in turn drives the fixed block to rotate. The rotation of the fixed block drives the filter screen to rotate. Because of the action of the first damping bearing, the rotation speed of the filter screen is slower than that of the rotating rod, so it will not affect the work of the striking block. This allows the material entering the casing to be evenly distributed on the top of the filter screen.

[0015] Preferably, a return spring is fixedly connected to the inner wall of the pressure rod, and an L-shaped rod is fixedly connected to one end of the return spring near the support rod. A toggle rod is fixedly connected to the wall of the support rod.

[0016] When the pressure rod is crushing, it rotates due to friction. The rotation of the pressure rod drives the internal return spring to rotate, which in turn drives the L-shaped rod to rotate. When the L-shaped rod comes into contact with the actuating rod fixedly connected to the support rod, the L-shaped rod rotates, and the return spring is stressed. When the L-shaped rod and the actuating rod are misaligned, the L-shaped rod returns to its original position under the force of the return spring, striking the inside of the pressure rod. This causes the pressure rod to vibrate.

[0017] Preferably, the end of the actuating lever away from the support rod is arc-shaped.

[0018] This reduces friction and protects the device.

[0019] Preferably, the stirring mechanism includes a reciprocating groove, a lead screw nut, a second damping bearing, a sleeve rod, and a stirring blade. The reciprocating groove is located on the rod wall near the lower end of the rotating rod. The lead screw nut is helically driven on the surface of the reciprocating groove. The second damping bearing is fixedly connected to the outside of the lead screw nut. The sleeve rod is fixedly connected to the outside of the second damping bearing. The stirring blade is fixedly connected to the outside of the sleeve rod.

[0020] When the rotating rod rotates, it drives the reciprocating groove to rotate, which in turn drives the lead screw nut to rotate. The lead screw nut then drives the second damping bearing to rotate, which in turn drives the sleeve rod to rotate. The sleeve rod then drives the stirring blades to rotate. Because the stirring blades are obstructed when the rotating rod rotates, the second damping bearing cannot rotate at the same speed as the rotating rod. This prevents the lead screw nut from rotating synchronously with the rotating rod. As a result, the lead screw nut moves up and down on the rod wall, which in turn drives the stirring blades to move up and down, allowing for stirring at different levels.

[0021] Preferably, a sealing ring is provided at the connection between the sleeve rod and the rotating rod.

[0022] To prevent materials from getting inside the sleeve and affecting its operation.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. It can crush the material that has clumped inside the shell, thus avoiding insufficient mixing caused by material clumping. At the same time, it can also avoid mechanical wear and tear on the mixing device when it directly mixes the clumps.

[0025] 2. When the L-shaped rod and the lever are misaligned, the L-shaped rod will return to its original position under the force of the return spring, striking the inside of the pressure rod. This will cause the pressure rod to vibrate, resulting in a more ideal crushing effect. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 4 The present invention provides a technical solution:

[0033] A JS polymer cement-based waterproof coating mixing device, such as Figure 1 As shown, the device includes an outer shell 1. A motor 2 is fixedly connected to the upper end of the outer shell 1. A feed pipe 3 is fixedly connected to the upper end of the outer shell 1 near the left side. A discharge pipe 9 is fixedly connected to the lower end of the outer shell 1 near the left side. A support leg 10 is fixedly connected to the lower end of the outer shell 1. A water pipe 4 is fixedly connected to the left side of the outer shell 1. A rotating rod 5 is fixedly connected to the lower end of the motor 2. A crushing mechanism 28 is provided on the left side of the rotating rod 5 near the upper end. A stirring mechanism 31 is provided at the center of the rotating rod 5.

[0034] During operation, the material to be stirred is fed into the interior of the outer shell 1 through the feed pipe 3, and an appropriate amount of water is introduced through the water pipe 4. At this time, the motor 2 drives the rotating rod 5 to rotate, which in turn drives the stirring mechanism 31 to work. The stirring mechanism 31 can move up and down to stir, which can avoid the material from separating and the phenomenon of uneven stirring when stirring horizontally. At the same time, the crushing mechanism 28 can crush the material that has entered the interior of the outer shell 1, which can avoid the phenomenon of insufficient stirring caused by material clumping. At the same time, this can avoid the mechanical wear and tear of the stirring device when directly stirring the clumped material.

[0035] As one embodiment of the present invention, such as Figure 2 and Figure 3As shown, the crushing mechanism 28 includes a support rod 16, a pressure rod 6, a filter screen 7, a fixing block 22, a vertical rod 23, a horizontal rod 24, a striking block 25, a protrusion 26, and a support plate 27. The support rod 16 is movably connected to the left side of the rod wall of the rotating rod 5. The pressure rod 6 is rotatably connected to the rod wall of the support rod 16. The filter screen 7 is fixedly connected to the inner wall of the outer casing 1 near the upper end. The fixing block 22 is fixedly connected to the center of the filter screen 7. The vertical rod 23 is fixedly connected to the lower end of the fixing block 22 near both sides. The horizontal rod 24 is rotatably connected to the lower end of the vertical rod 23. The striking block 25 is fixedly connected to the side of the horizontal rod 24 away from the rotating rod 5. The support plate 27 is fixedly connected to the center of both sides of the rod wall of the rotating rod 5. The protrusion 26 is fixedly connected to the upper end of the support plate 27.

[0036] During operation, when the rotating rod 5 rotates, it drives the support rod 16 to move. The movement of the support rod 16 drives the pressure rod 6 to move, which in turn squeezes the incoming material. The rotation of the rotating rod 5 drives the support plate 27 to rotate, which in turn drives the protrusion 26 to rotate. When the protrusion 26 moves and squeezes against the crossbar 24, it causes the crossbar 24 to rotate upward. When the crossbar 24 rotates, it drives the striking block 25 to rotate upward. This causes the material to be struck by the filter screen 7, accelerating the passage of the material through the filter screen 7 into the lower part of the inner shell 1. It should be noted that because the vertical rod 23 is fixedly connected to the fixed block 22, the rotation of the crossbar 24 will cause the striking block 25 to rotate. In order to better fit the striking block 25 with the filter screen 7, the striking block 25 is rotatably connected to the crossbar 24. This can crush the material clumps and speed up the stirring rate.

[0037] As one embodiment of the present invention, such as Figure 2 As shown, a sliding groove 18 is provided on the left side of the rod wall of the rotating rod 5. A slider 20 is slidably connected inside the sliding groove 18. The left side of the slider 20 is fixedly connected to the right side of the support rod 16. A first spring 19 is fixedly connected to the upper end of the slider 20.

[0038] During operation, because the size of the lumps is uneven, when the lumps come into contact with the pressure rod 6, the pressure rod 6 drives the support rod 16 to move upward. The support rod 16 drives the slider 20 to move inside the slide groove 18, while squeezing the first spring 19. This can prevent the hardness of the lumps from being too large and damaging the device, thus improving the practicality of the device.

[0039] As one embodiment of the present invention, such as Figure 2 As shown, the first damping bearing 21 is rotatably connected inside the fixed block 22, and the inside of the first damping bearing 21 is fixedly connected to the rod wall of the rotating rod 5. The first bearing 14 is fixedly connected to the outside of the filter screen 7.

[0040] During operation, because the feed pipe 3 is located on the upper left side of the outer casing 1, the material will accumulate on one side when it enters the outer casing 1. When the rotating rod 5 rotates, it drives the first damping bearing 21 to rotate. The first damping bearing 21 drives the fixed block 22 to rotate. The rotation of the fixed block 22 drives the filter screen 7 to rotate. Because of the action of the first damping bearing 21, the rotation speed of the filter screen 7 is slower than the rotation speed of the rotating rod 5, so it will not affect the operation of the striking block 25. In this way, the material entering the outer casing 1 can be evenly distributed on the filter screen 7, which improves the practicality of the device.

[0041] As one embodiment of the present invention, such as Figure 4 As shown, a return spring 13 is fixedly connected to the inner wall of the pressure rod 6. An L-shaped rod 15 is fixedly connected to one end of the return spring 13 near the support rod 16. A toggle rod 17 is fixedly connected to the wall of the support rod 16. The end of the toggle rod 17 away from the support rod 16 is arc-shaped.

[0042] During operation, when the pressure rod 6 is crushing, it rotates due to friction. The rotation of the pressure rod 6 drives the internal return spring 13 to rotate, which in turn drives the L-shaped rod 15 to rotate. When the L-shaped rod 15 contacts the actuating rod 17 fixedly connected to the support rod 16, the L-shaped rod 15 rotates, and the return spring 13 is stressed. When the L-shaped rod 15 and the actuating rod 17 are misaligned, the L-shaped rod 15 returns to its original position under the force of the return spring 13, striking the inside of the pressure rod 6. This causes the pressure rod 6 to vibrate, resulting in a more ideal crushing effect.

[0043] As one embodiment of the present invention, such as Figure 2 As shown, the stirring mechanism 31 includes a reciprocating groove 11, a lead screw nut 29, a second damping bearing 30, a sleeve rod 12, and a stirring blade 8. The reciprocating groove 11 is located on the lower end of the rod wall of the rotating rod 5. The lead screw nut 29 is helically driven on the surface of the reciprocating groove 11. The second damping bearing 30 is fixedly connected to the outside of the lead screw nut 29. The sleeve rod 12 is fixedly connected to the outside of the second damping bearing 30. The stirring blade 8 is fixedly connected to the outside of the sleeve rod 12. A sealing ring is provided at the connection between the sleeve rod 12 and the rotating rod 5.

[0044] During operation, when the rotating rod 5 rotates, it drives the reciprocating groove 11 to rotate. The rotation of the reciprocating groove 11 drives the lead screw nut 29 to rotate, which in turn drives the second damping bearing 30 to rotate. The second damping bearing 30 drives the sleeve rod 12 to rotate, which in turn drives the stirring blade 8 to rotate. When the rotating rod 5 rotates, the stirring blade 8 is obstructed, so the second damping bearing 30 cannot rotate at the same speed as the rotating rod 5. This prevents the lead screw nut 29 from rotating synchronously with the rotating rod 5. At this time, the lead screw nut 29 moves up and down on the rod wall of the rotating rod 5, which in turn drives the stirring blade 8 to move up and down. This allows for stirring at different levels, making the stirring more thorough and uniform.

[0045] Working principle:

[0046] During operation, the material to be mixed is fed into the interior of the outer shell 1 through the feed pipe 3, and an appropriate amount of water is introduced through the water pipe 4. At this time, the motor 2 drives the rotating rod 5 to rotate, which in turn drives the mixing mechanism 31. The mixing mechanism 31 can move up and down to mix, which can prevent the material from separating and avoid uneven mixing during horizontal mixing. At the same time, the crushing mechanism 28 crushes the material entering the outer shell 1, which can prevent the material from clumping and causing insufficient mixing. This also avoids mechanical wear on the mixing device itself when directly mixing clumped material. When the rotating rod 5 rotates, it drives the support rod 16 to move. The movement of the support rod 16 drives the pressure rod 6 to move, which in turn crushes the incoming material. The extrusion and rotation of the rotating rod 5 cause the support plate 27 to rotate, which in turn causes the protrusion 26 to rotate. When the protrusion 26 moves and is extruded from the crossbar 24, the crossbar 24 rotates upwards. This rotation of the crossbar 24 causes the striking block 25 to rotate upwards, thus creating an impact with the filter screen 7. This accelerates the material's passage through the filter screen 7 and its entry into the lower part of the inner casing 1. It should be noted that because the vertical rod 23 is fixedly connected to the fixed block 22, the rotation of the crossbar 24 causes the striking block 25 to rotate. To better ensure the striking block 25 adheres to the filter screen 7, the striking block 25 is rotatably connected to the crossbar 24. This crushes material clumps and accelerates the mixing rate. Because the clumps are of uneven size, when the pressing rod 6... When the material comes into contact with the agglomerates, the pressure rod 6 moves the support rod 16 upwards. The support rod 16 then moves the slider 20 inside the groove 18, simultaneously compressing the first spring 19. This prevents the agglomerates from becoming too hard and damaging the device, thus improving its practicality. Because the feed pipe 3 is located on the upper left side of the outer casing 1, the material accumulates on one side when it enters the casing 1. When the rotating rod 5 rotates, it drives the first damping bearing 21 to rotate. The first damping bearing 21 drives the fixed block 22 to rotate, which in turn drives the filter screen 7 to rotate. Due to the action of the first damping bearing 21, the rotation speed of the filter screen 7 is slower than that of the rotating rod 5, so it does not affect the operation of the striking block 25. This allows the material entering the outer casing 1 to be processed more efficiently. When the internal material is evenly distributed on the filter screen 7, the practicality of the device is improved. When the pressure rod 6 is crushing, it rotates due to friction. The rotation of the pressure rod 6 drives the internal return spring 13 to rotate, which in turn drives the L-shaped rod 15 to rotate. When the L-shaped rod 15 contacts the actuating rod 17 fixedly connected to the support rod 16, the L-shaped rod 15 rotates, and the return spring 13 is stressed. When the L-shaped rod 15 and the actuating rod 17 are misaligned, the L-shaped rod 15 returns to its original position under the force of the return spring 13, striking the inside of the pressure rod 6. This causes the pressure rod 6 to vibrate, making the crushing effect more ideal. When the rotating rod 5 rotates, it drives the reciprocating groove 11 to rotate.When the reciprocating groove 11 rotates, it drives the lead screw nut 29 to rotate. The rotation of the lead screw nut 29 drives the second damping bearing 30 to rotate, which in turn drives the sleeve rod 12 to rotate. The sleeve rod 12 then drives the stirring blade 8 to rotate. When the rotating rod 5 rotates, the stirring blade 8 is obstructed. Therefore, the second damping bearing 30 cannot rotate at the same speed as the rotating rod 5. This prevents the lead screw nut 29 from rotating synchronously with the rotating rod 5. At this time, the lead screw nut 29 moves up and down on the rod wall of the rotating rod 5, driving the stirring blade 8 to move up and down as well. This allows for stirring at different levels, resulting in more thorough and uniform stirring.
