Description

Technical Field

[0001] The present application relates to the field of mixers, and in particular to a mixer that is convenient for unloading materials. Background Art

[0002] Paint is a protective film applied to the surface of the object to be protected or decorated. During the production process of paint, auxiliary materials are often needed to mix the paint. Usually, a mixer is used to stir the paint to make it fully mixed.

[0003] In the traditional mixer, due to the centrifugal force during the mixing process, the powder material tends to move toward the wall of the mixing bin and concentrate, resulting in a large amount of powder material remaining on the wall of the mixing bin. When the mixture is discharged, these residues often cannot be completely discharged, resulting in waste and insufficient utilization of raw materials. In order to solve the above problems, the existing mixer is equipped with a vibrator on the bin wall, trying to clean the powder off the inner wall by vibration. However, the actual effect is not ideal, and the vibrator is often difficult to completely remove the residual powder. This incomplete cleaning not only affects the mixing effect of the mixer, but may also cause quality problems in subsequent production. Utility Model Content

[0004] The purpose of this application is to overcome the above technical problems and provide a powder mixer that is easy to feed. The mixer has the advantages of simple structure, convenient operation, good mixing effect, etc., and can effectively solve the technical problems of insufficient utilization of powder raw materials and serious residual problems in the prior art.

[0005] The present application provides a mixer that is convenient for unloading and adopts the following technical solution:

[0006] A mixer convenient for unloading materials comprises a bracket, a vertically arranged mixing barrel is fixedly connected to the bracket, a main stirring shaft is vertically arranged in the mixing barrel, an auger is fixedly connected to the outer circumference of the main stirring shaft, a driving motor is arranged at one end of the main stirring shaft, the driving motor drives the main stirring shaft to rotate, a discharge pipe is fixedly connected to the lower end of one side of the mixing barrel, a cover plate is arranged on the upper side of the mixing barrel, an auxiliary stirring shaft is vertically arranged in the mixing barrel, a transmission assembly is provided together with the auxiliary stirring shaft and the auxiliary stirring shaft and the main stirring shaft can revolve around the main stirring shaft and rotate at the same time under the action of the transmission assembly, a scraper is arranged on the outer circumference of the auxiliary stirring shaft and the scraper can abut against the inner wall of the mixing barrel.

[0007] By adopting the above technical solution, when the driving motor drives the main stirring shaft to rotate, the transmission assembly will simultaneously drive the auxiliary stirring shaft to revolve and rotate around the main stirring shaft. Since scrapers are arranged on the outer peripheral surface of the auxiliary stirring shaft, these scrapers can move on the inner wall of the mixing barrel with the revolution and rotation of the auxiliary stirring shaft, thereby effectively scraping off the powder material attached to the inner wall of the mixing barrel. This design not only improves the utilization rate of powder materials and reduces the waste of raw materials, but also ensures that the mixed materials in the mixer are more uniform, thereby improving the mixing effect.

[0008] Optionally, the transmission assembly includes an outer ring gear, a sun gear and a planetary gear, the outer ring gear is rotatably connected to the bracket, the sun gear is coaxially fixed to the main stirring shaft, and the planetary gear is coaxially connected to the auxiliary stirring shaft.

[0009] By adopting the above technical solution, the auxiliary stirring shaft can be driven by the driving motor and can rotate around the main stirring shaft at the same time through the transmission of the planetary gear system. This planetary gear transmission method has the advantages of compact structure, large transmission ratio, and high load capacity. In the mixer, it can ensure that the auxiliary stirring shaft moves in a complex trajectory in the mixing barrel, so as to more effectively clean the powder material on the inner wall of the mixing barrel.

[0010] Optionally, a plurality of the auxiliary stirring shafts are provided, and a plurality of the planetary gears are also provided, and the planetary gears correspond to the auxiliary stirring shafts one by one.

[0011] By adopting the above technical solution, the mixing effect and cleaning ability of the mixer are further enhanced. The setting of multiple auxiliary stirring shafts increases the number of scrapers, which not only covers a wider area in the mixing barrel, but also can generate stirring force at different positions and angles, making the materials mixed more evenly. At the same time, multiple scrapers can more comprehensively clean the powder materials attached to the inner wall of the mixing barrel, reduce the waste of raw materials, and improve the utilization rate of powder materials.

[0012] Optionally, the bottom wall of the mixing barrel is provided with an annular relief portion for the auxiliary stirring shaft to revolve, and a baffle is rotatably connected above the bottom wall of the mixing barrel, the outer circumference of the baffle abuts against the inner wall of the mixing barrel, the baffle is fixedly connected to the auxiliary stirring shaft and is rotatably connected to the main stirring shaft.

[0013] By adopting the above technical solution, the annular clearance portion provided on the bottom wall of the mixing barrel provides sufficient space for the revolution of the auxiliary stirring shaft, ensuring that the auxiliary stirring shaft will not interfere with the bottom wall of the mixing barrel during the revolution. The setting of the baffle plays a certain sealing role, preventing the material from leaking from the clearance portion at the bottom of the mixing barrel during the mixing process.

[0014] Optionally, a sealing strip is fixedly connected to the outer circumference of the baffle, and a sealing strip is also fixedly connected to the inner circumference of the baffle, and the baffle is sealedly connected to the mixing barrel and the main stirring shaft through the sealing strip.

[0015] By adopting the above technical solution, sealing strips are fixed to the outer circumference and inner circumference of the baffle, which ensure a close fit between the baffle and the inner wall of the mixing barrel and the main stirring shaft, effectively preventing leakage of materials during the mixing process and improving the operational safety and reliability of the mixer.

[0016] Optionally, the scraper is provided with a sleeve, the sleeve is sleeved on the outside of the auxiliary stirring shaft, the scraper is connected to the auxiliary stirring shaft through the sleeve, the sleeve is provided with a locking assembly for locking, and the sleeve can slide and lock along the length direction of the auxiliary stirring shaft.

[0017] By adopting the above technical solution, the scraper can slide and lock along the length direction of the auxiliary stirring shaft, so as to adjust the contact position between the scraper and the inner wall of the mixing barrel. This adjustability enables the operator to adjust the scraper position according to actual needs, ensuring that the scraper can effectively clean the powder material on the inner wall of the mixing barrel.

[0018] Optionally, the auxiliary stirring shaft is provided with a positioning hole along the length direction, and the locking assembly includes a latch, and the latch is inserted into the positioning hole to achieve locking of the sleeve.

[0019] By adopting the above technical solution, the sleeve and the auxiliary stirring shaft can be quickly locked and released. This locking method is simple and reliable, easy to operate, and can quickly and effectively fix the position of the scraper, making the use of the device more convenient and flexible.

[0020] Optionally, the scraper is detachably connected to the auxiliary stirring shaft, and the scraper is made of elastic and wear-resistant material.

[0021] By adopting the above technical solution, the scraper and the auxiliary stirring shaft are detachably connected. This design allows the scraper to be easily disassembled and replaced when it is worn or needs to be replaced, thereby extending the service life of the mixer. At the same time, the scraper is made of elastic wear-resistant material, which has good elasticity and wear resistance, and can maintain a stable contact force and scraping effect when scraping powder materials, while reducing the wear of the scraper itself.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The planetary gear transmission mechanism is used to drive the auxiliary stirring shaft to perform revolution and rotation, so that the scraper can scrape the powder residue on the inner wall of the mixing barrel more evenly, improving the mixing effect and raw material utilization rate, so that the powder in the mixing barrel can be fully discharged;

[0024] 2. The use of multiple auxiliary stirring shafts and scrapers further enhances the scraping effect and mixing uniformity, reduces the amount of powder residue and improves product quality.

[0025] 3. By setting the baffle and its sealing strip, the powder is effectively prevented from leaking from the gap between the bottom wall of the mixing barrel and the auxiliary stirring shaft, ensuring the cleanliness of the production environment and the stability of the mixing effect;

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0034] The present application embodiment discloses a mixer that is convenient for feeding. Figure 1 A mixer that is convenient for unloading includes a bracket 1, on which a vertically arranged mixing barrel 2 is fixedly connected, a main stirring shaft 3 is vertically arranged in the mixing barrel 2, and an auger 31 is fixedly connected to the outer circumference of the main stirring shaft 3 for stirring powder materials. A driving motor 32 is arranged at one end of the main stirring shaft 3, and the driving motor 32 is fixedly connected to the bracket 1, and the driving motor 32 drives the main stirring shaft 3 to rotate. A discharge pipe 21 is fixedly connected to the lower end of one side of the mixing barrel 2 for discharging the mixed powder material. A valve is installed on the discharge pipe 21 for controlling the discharge of the discharge pipe 21. A cover plate 22 is arranged on the upper side of the mixing barrel 2 for sealing the upper opening of the mixing barrel 2.

[0035] Reference Figure 2 , a plurality of auxiliary stirring shafts 4 are vertically arranged in the mixing barrel 2. In this embodiment, two auxiliary stirring shafts 4 are taken as an example. The two auxiliary stirring shafts 4 are respectively located on both sides of the main stirring shaft 3. The two auxiliary stirring shafts 4 and the main stirring shaft 3 are provided with a transmission assembly 5. The transmission assembly 5 includes an outer ring gear 51, a sun gear 52 and two planetary gears 53. The auxiliary stirring shaft 4 corresponds to the planetary gear 53 one by one. The outer ring gear 51 is rotatably connected to the bracket 1, the sun gear 52 is coaxially fixed to the main stirring shaft 3, and the planetary gear 53 is coaxially connected to the auxiliary stirring shaft 4. When the driving motor 32 drives the main stirring shaft 3 to rotate, the sun gear 52 rotates accordingly, and the outer ring gear 51 is driven to rotate through the planetary gear 53. The planetary gear 53 also revolves around the sun gear 52, thereby driving the auxiliary stirring shaft 4 to revolve around the main stirring shaft 3, and the planetary gear 53 rotates at the same time.

[0036] Reference Figure 2In order to facilitate the revolution of the auxiliary stirring shaft 4, the bottom wall of the mixing barrel 2 is provided with an annular clearance portion 23 for the revolution of the auxiliary stirring shaft 4. Due to the opening of the clearance portion 23, the powder will fall from the position of the clearance portion 23 to the position of the transmission assembly 5, so a baffle 8 is rotatably connected above the bottom wall of the mixing barrel 2, and the outer circumference of the baffle 8 abuts against the inner wall of the mixing barrel 2. The baffle 8 is fixedly connected to the auxiliary stirring shaft 4 and is rotatably connected to the main stirring shaft 3. When the auxiliary stirring shaft 4 revolves, the baffle 8 moves accordingly. The setting of the baffle 8 can reduce the possibility of powder leaking from the gap between the bottom wall of the mixing barrel 2 and the auxiliary stirring shaft 4, affecting the normal operation of the transmission assembly 5, and improving the reliability of the device.

[0037] Furthermore, a sealing strip (not shown in the figure) is fixedly connected to the outer circumference of the baffle 8, and a sealing strip (not shown in the figure) is also fixedly connected to the inner circumference of the baffle 8. The baffle 8 is sealedly connected to the mixing barrel 2 and the main stirring shaft 3 through the sealing strip. The provision of the sealing strip can further improve the sealing performance and prevent powder leakage.

[0038] Reference Figure 2 A plurality of scrapers 6 are arranged on the outer peripheral surface of each auxiliary stirring shaft 4. The plurality of scrapers 6 can abut against the inner wall of the mixing barrel 2 as the auxiliary stirring shaft 4 rotates, and the powder material attached to the inner wall of the mixing barrel 2 is scraped off, thereby further improving the mixing effect and reducing powder residue.

[0039] Reference Figure 2 and Figure 3 , the scraper 6 is fixedly connected with a sleeve 61, and the sleeve 61 is sleeved on the outside of the auxiliary stirring shaft 4. The scraper 6 is connected to the auxiliary stirring shaft 4 through the sleeve 61, and the sleeve 61 is provided with a locking assembly 7 for locking. A spline is fixedly connected inside the sleeve 61, and the auxiliary stirring shaft 4 is provided with a vertical keyway. The spline slides in the keyway so that the sleeve 61 can slide along the length direction of the auxiliary stirring shaft 4, and the locking assembly 7 can realize the locking of the sleeve 61. By adjusting the position of the sleeve 61, the contact position between the scraper 6 and the inner wall of the mixing barrel 2 can be adjusted, so that the worker can adjust the height of the scraper 6 according to actual needs.

[0040] Specifically, refer to Figure 2 The auxiliary stirring shaft 4 is provided with a positioning hole 421 along the length direction, and the locking assembly 7 includes a latch 71, which is inserted into the positioning hole 421 to lock the sleeve 61. The cooperation between the latch 71 and the positioning hole 421 can realize the quick locking and unlocking of the sleeve 61, and the operation is convenient.

[0041] Further, see Figure 2The scraper 6 and the sleeve 61 are detachably connected by bolts, and the scraper 6 is made of elastic wear-resistant materials such as rubber, silicone or polyurethane. The detachable connection facilitates the replacement of the worn scraper 6 and prolongs the service life; the elastic wear-resistant material can improve the wear resistance and service life of the scraper 6.

[0042] Reference Figure 2 Each auxiliary stirring shaft 4 is divided into a fixed part 41 and a movable part 42 along the length direction, and the fixed part 41 and the movable part 42 are detachably connected. The sleeve 61 is connected to the movable part 42, one end of the fixed part 41 is fixedly connected to the planetary gear 53 coaxially, and the other end is provided with a spline, and the movable part 42 is provided with a keyway near the end of the fixed part 41. By inserting one end of the movable part 42 with the keyway outside the spline, the fixed part 41 and the movable part 42 are detachably connected, and the fixed part 41 and the movable part 42 can rotate synchronously. The detachable connection facilitates the maintenance and replacement of the auxiliary stirring shaft 4, and also facilitates the replacement of the scraper 6.

[0043] The arrangement of multiple auxiliary stirring shafts 4 can reduce the length of the sleeve 61 and the scraper 6 on each auxiliary stirring shaft 4, and the inner wall of the entire mixing barrel 2 can also be cleaned by staggering the multiple sleeves 61 along the height direction of the mixing barrel 2. This not only ensures the cleaning effect, but also reduces the weight of the sleeve 61 connected to each auxiliary stirring shaft 4, making it easier to separate the movable part 42 from the fixed part 41.

[0044] Furthermore, a wear-resistant layer (not shown in the figure) is fixedly connected to the inner wall of the mixing barrel 2. The wear-resistant layer can increase the service life of the mixing barrel 2. Figure 2 A plurality of auxiliary stirring shafts 4 are movably connected to the top of the main stirring shaft 3 by a support rod 9, and the ends of the auxiliary stirring shaft 4 and the main stirring shaft 3 are provided with a support rod 9, and the support rod 9 is rotatably connected to the mixing barrel 2. The support rod 9 supports each auxiliary stirring shaft 4 to ensure the stability of the auxiliary stirring shaft 4 during rotation.

[0045] The implementation principle of a mixer that is easy to unload in an embodiment of the present application is as follows: the powder raw materials to be mixed are added into the mixing barrel 2 through the upper cover plate 22 of the mixing barrel 2. The drive motor 32 is started, and the drive motor 32 drives the main stirring shaft 3 to rotate, and the auger 31 on the main stirring shaft 3 preliminarily mixes the powder raw materials. At the same time, the transmission assembly 5 drives the auxiliary stirring shaft 4 to revolve around the main stirring shaft 3 and rotate, and the scraper 6 on the auxiliary stirring shaft 4 abuts against the inner wall of the mixing barrel 2, scrapes off the powder raw materials adhering to the inner wall of the mixing barrel 2 and mixes them again, thereby improving the mixing effect and raw material utilization. After the mixing is completed, the discharge pipe 21 is opened, and the mixed powder raw materials are discharged from the discharge pipe 21, completing the entire mixing process.

[0046] In addition, according to actual needs, the operator can adjust the position of the scraper 6 and the inner wall of the mixing barrel 2 by adjusting the position of the sleeve 61 on the auxiliary stirring shaft 4, and by adjusting multiple scrapers 6 to different heights, the different heights of the entire mixing barrel 2 can be cleaned. At the same time, the scraper 6 is made of elastic wear-resistant material, has good wear resistance and service life, and the detachable connection also facilitates the replacement and maintenance of the scraper 6.

[0047] The embodiment of the present application has the advantages of simple structure, convenient operation, good mixing effect, etc., and can effectively solve the technical problems of insufficient utilization of powder raw materials and serious residue problems in the prior art, and improve production efficiency and product quality.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
