Description

Technical Field

[0001] This utility model relates to the field of latex powder conveying technology, and in particular to a latex powder conveying device. Background Technology

[0002] Chemical building materials generally refer to materials used in construction projects, produced from organic polymers and their composites. They possess advantages such as low density, low energy consumption, good corrosion resistance, strong decorative properties, reduced transportation costs, and energy-saving insulation. With the rapid development of urban construction and the construction industry, chemical building materials have become a pillar industry of the national economy. Redispersible latex powder is a commonly used cement mortar additive, widely used due to its convenient transportation, easy storage, and easy-to-control mixing ratio when blended with cement mortar on-site.

[0003] Traditional screw conveyors, due to their fixed inclination, are severely limited in terms of storage and usage scenarios. For example, they are difficult to transport into low-ceilinged rooms, and even if placed there, they cannot operate properly. Furthermore, these fixed-inclination screw conveyors can only adapt to equipment of specific heights, failing to flexibly handle inlet or outlet heights. This often leads to inaccurate connections when interfacing with various equipment, easily causing powder leakage. This not only affects production efficiency but also pollutes the environment and hinders the smooth flow of powder to the next process. Therefore, to address these issues, a latex powder conveying device is proposed. Utility Model Content

[0027] 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.

[0028] Reference Figures 1 to 3One embodiment of this utility model provides: the movable base 1 is made of sturdy and durable metal to ensure the stability of the device during operation. Its shape is a cuboid structure, and brakeable casters are installed at the four corners of the bottom of the base, facilitating flexible movement and positioning of the device in different work environments. A motor 3 is fixedly connected to the left end of the transport pipe 2. The motor 3 is a three-phase asynchronous motor with appropriate power, and its casing is made of high-strength aluminum alloy, which not only provides good heat dissipation but also effectively reduces the overall weight of the motor 3. The motor 3 is tightly fixed to the left end casing of the transport pipe 2 with bolts, ensuring that the motor 3 will not shift during high-speed operation.

[0029] The bottom end of the transport pipe 2 is rotatably connected to the top left end of the movable base 1. The transport pipe 2 is made of stainless steel, which has good wear resistance and corrosion resistance, effectively preventing the latex powder from wearing and corroding the inner wall of the pipe. The drive end of the motor 3 is fixedly connected to the bottom end of the auger 4. The drive end of the motor 3 is rigidly connected to the bottom end of the auger 4 through a coupling, ensuring that the torque output by the motor 3 can be stably transmitted to the auger 4. The auger 4 is externally rotatably connected to the inner wall of the transport pipe 2. The auger 4 consists of spiral blades and a central shaft.

[0030] A hopper 5 is fixedly connected to the top left end of the transport pipe 2. The hopper 5 has an inverted conical structure, with its large end tightly connected to the top left end of the transport pipe 2 by welding. The small end is used to facilitate the pouring of latex powder, and reinforcing ribs are provided at the edge of the large end to enhance the structural strength of the hopper 5. A discharge port 6 is fixedly connected to the top end of the transport pipe 2. The discharge port 6 is made of stainless steel, the same material as the transport pipe 2. One end of the discharge port 6 is welded to the top end of the transport pipe 2, and the other end is used to transport the latex powder in the transport pipe 2 to a designated location. The diameter of the discharge port 6 is designed reasonably according to the actual conveying requirements.

[0031] refer to Figure 2 , Figure 4 A collar 7 is fixedly connected to the middle of the transport pipe 2. The collar 7 is firmly fixed to the middle position of the transport pipe 2 by welding. The main function of the collar 7 is to ensure stability when the height of the transport pipe 2 is adjusted. Auxiliary rods 8 are fixedly connected to both the front and rear sides of the collar 7. The auxiliary rods 8 are made of solid metal. One end of the auxiliary rod 8 is tightly connected to the collar 7 by welding, and the other end of the auxiliary rod 8 slides within the pipes fixed on both sides of the sleeve frame 10. During the height adjustment of the transport pipe 2, the auxiliary rods 8 assist the rack rod 9 in sliding stably, enhancing the stability of the entire device.

[0032] A rack 9 is rotatably connected to the bottom end of the collar 7. The rack 9 is made of a long strip of metal, and one side surface of the rack 9 is machined with evenly distributed teeth. The top end of the rack 9 is rotatably connected to the bottom end of the collar 7 via a rotating shaft, allowing the rack 9 to slide up and down as the height of the transport pipe 2 needs to be adjusted. The auxiliary rod 8 is externally slidably connected to a sleeve 10. The sleeve 10 adopts a frame structure, which is welded from multiple metal square tubes. Pipes for sliding the auxiliary rod 8 are fixed on both sides of the sleeve 10. The inner diameter of the pipes is adapted to the outer diameter of the auxiliary rod 8 to ensure that the auxiliary rod 8 can slide smoothly within it.

[0033] A protective shell 11 is fixedly connected to the top of the sleeve 10. A second driven gear 16 is fixedly connected to the outside of the connecting shaft 14. The external teeth of the second driven gear 16 mesh with the external teeth of the rack rod 9. The protective shell 11 is made of bent and welded thin metal sheet, and has an internal space to accommodate the rocker arm 12, the driving gear 13, the connecting shaft 14, the first driven gear 15, and the second driven gear 16, serving as protection and dustproof. The rack rod 9 is slidably connected to the inner wall of the protective shell 11. A guide groove is provided on the inner wall of the protective shell 11, and the tooth side of the rack rod 9 cooperates with the guide groove to ensure the accuracy and stability of the rack rod 9 during the up and down sliding process.

[0034] The rocker arm 12 and the protective shell 11 are externally equipped with a limiting component for fixing the position of the rack 9. The limiting component includes a ratchet 17, which is made of a metal disc with evenly distributed teeth machined on its outer edge. The middle part of the ratchet 17 is fixedly connected to the outside of the rocker arm 12, and the ratchet 17 and the rocker arm 12 are ensured to rotate synchronously by welding. The front end of the protective shell 11 has a groove 18. The shape and size of the groove 18 can ensure that the pawl block 20 and the spring plate 19 have sufficient rotation space. The spring plate 19 is fixedly connected to the front side of the groove 18. The spring plate 19 is made of a highly elastic metal sheet. One end of the spring plate 19 is fixed to the front side of the groove 18, and the other end abuts against the pawl block 20.

[0035] A pawl block 20 is rotatably connected to the front side of the groove 18. The pawl block 20 is made of metal. One end of the pawl block 20 is rotatably connected to the front side of the groove 18 via a rotating shaft, and the other end has a claw tip that matches the teeth of the ratchet 17. The outer top of the pawl block 20 is engaged with the outer teeth of the ratchet 17. The outer top of the spring plate 19 is engaged with the pawl block 20. With this structure, when the rocker arm 12 is shaken, the ratchet 17 rotates synchronously. Under the action of the spring plate 19, the pawl block 20 is always engaged with the teeth of the ratchet 17, which achieves a self-locking effect and prevents the device from shaking accidentally.

[0036] The rocker arm 12 and the protective shell 11 are provided with a limiting component for fixing the position of the rack 9. The limiting component includes a ratchet 17. The middle part of the ratchet 17 is fixedly connected to the outside of the rocker arm 12. The front end of the protective shell 11 has a groove 18. A spring plate 19 is fixedly connected to the front side of the groove 18. A pawl block 20 is rotatably connected to the front side of the groove 18. The top of the pawl block 20 is engaged with the external teeth of the ratchet 17. The top of the spring plate 19 is engaged with the pawl block 20.

[0037] refer to Figure 3 A sleeve 22, made of metal tubing, is fixedly connected to the left end of the movable base 1. One end of the sleeve 22 is welded to the left end of the movable base 1, while the other end is open. A limiting block 23, also made of metal, is slidably connected inside the sleeve 22. Its shape matches the inner diameter of the sleeve 22, allowing it to slide smoothly within the sleeve. Two upright springs 24, made of high-strength spring steel, are fixedly connected to the top of the limiting block 23. One end of each spring is welded to the top of the limiting block 23, and the other end is fixed to the top of the inner wall of the sleeve 22. When the conveying pipe 2 transmits the vibration generated by the rotation of the auger 4, the limiting block 23 moves up and down within the sleeve 22, and the upright springs 24 absorb and buffer the vibration. The bottom end of the upright spring 24 is fixedly connected to the inner wall of the upright spring 24. Dampers 21 are rotatably connected to both the front and rear sides of the sleeve 10. The dampers 21 are hydraulic dampers, one end of which is rotatably connected to both the front and rear sides of the sleeve 10 via a rotating shaft, and the other end is rotatably connected to the top left side of the movable base 1 via a rotating shaft. When the motor 3 starts and drives the auger 4 to rotate and transport latex powder, the transport pipe 2 transmits the vibration generated by the rotation of the auger 4 to the dampers 21 and the limiting block 23 through the auxiliary rod 8 and the sleeve 10. At this time, the air pressure inside the damper 21, combined with the external spring, partially absorbs the transmitted vibration, while the limiting block 23 absorbs it again through the upright spring 24 inside the sleeve 22, achieving a buffering effect and reducing the impact of vibration on the overall performance of the device.

[0038] Working principle: When the height of the transport pipe 2 needs to be adjusted, the operator shakes the rocker arm 12. The teeth of the drive gear 13 at one end of the rocker arm 12 mesh with the first driven gear 15, so shaking the rocker arm 12 drives the first driven gear 15 to rotate. The first driven gear 15 is fixed on the connecting shaft 14, so when the first driven gear 15 rotates, the connecting shaft 14 rotates synchronously, thereby driving the second driven gear 16 on the connecting shaft 14 to rotate. The teeth of the second driven gear 16 mesh with the teeth of the rack 9, so that when the second driven gear 16 rotates, it drives the rack 9 to slide up and down. This multi-gear transmission method saves effort and is convenient for operators to adjust. The rack 9 is connected to the transport pipe 2 through the collar 7, which is fixed in the middle of the transport pipe 2. Therefore, the sliding of the rack 9 allows the height of the transport pipe 2 to be adjusted with one side of the movable base 1 as the center, which is convenient for docking with equipment of different heights.

[0039] During the height adjustment of the transport pipe 2, the auxiliary rods 8 fixed on both sides of the collar 7 slide within the pipes fixed on both sides of the sleeve 10 under the drive of the rack 9. The sliding of the auxiliary rods 8 assists the rack 9 in stable movement, enhancing the stability of the entire adjustment process. Simultaneously, a ratchet 17 is fixed externally to the rocker arm 12; when the rocker arm 12 is rocked, the ratchet 17 rotates synchronously. The pawl block 20, externally engaged with the ratchet 17, remains engaged with the teeth of the ratchet 17 under the action of the spring plate 19. One end of the spring plate 19 is fixed to the front side of the groove 18 at the front end of the protective shell 11, and the other end abuts against the pawl block 20, causing the pawl block 20 to tightly lock the ratchet 17, achieving a self-locking effect and effectively preventing accidental shaking of the device. When it is necessary to lower the height of the transport pipe 2, the operator only needs to press one side of the pawl block 20 against the ratchet 17, disengaging the pawl tip from the ratchet 17, releasing the self-locking state, and then rocking the rocker arm 12 in the opposite direction to lower the transport pipe 2.

[0040] When motor 3 starts and drives auger 4 to rotate and transport latex powder, the transport pipe 2 transmits the vibration generated by the rotation of auger 4. The vibration is first transmitted to the sleeve 10 through the auxiliary rods 8 on both sides of the collar 7, and then transmitted by the sleeve 10 to the damper 21 and the limiting block 23. The dampers 21 set on the front and rear sides of the bottom of the sleeve 10 are hydraulic dampers 21. The internal air pressure and the external spring work together to absorb part of the vibration energy. The limiting block 23 at the middle of the top of the sleeve 10 is located in the sleeve 22 fixed to the left end of the movable base 1. Two upright springs 24 are connected to the top of the limiting block 23, and the other end of the upright springs 24 is fixed to the top of the inner wall of the sleeve 22. The limiting block 23 moves up and down in the sleeve 22, and absorbs the vibration energy again through the upright springs 24, thereby achieving a buffering effect and reducing the impact of vibration on the overall performance of the device.
