Abstract
Description
A drum-type premixer for processing animal formula milk powder Technical Field
[0001] This utility model relates to the field of milk powder processing technology, specifically a barrel-type premixer for processing animal formula milk powder. Background Technology
[0002] Animal formula milk powder is used to feed calves, lambs, piglets, etc. When preparing animal formula milk powder, it is often necessary to premix and stir the additives. After the premixing and stirring is completed, the additives and raw materials are mixed and stirred to achieve the effect of mixing the milk powder. A stirring device is needed during the premixing process to achieve the purpose of quickly stirring the additives, avoiding the use of manual mixing, and speeding up the mixing process and improving work efficiency.
[0003] After mixing, some milk powder adheres to the inner wall of the mixing drum and the mixing mechanism, resulting in milk powder waste. Although some mixing devices have scrapers on the mixing mechanism, the scrapers rotate simultaneously when the mixing mechanism is mixing the milk powder, which causes wear on the scrapers. Over time, the scrapers will not be able to make close contact with the inner wall, affecting the scraping effect. At the same time, when the milk needs to be discharged after mixing, the milk powder will accumulate and squeeze against each other at the discharge port, which can easily cause blockage of the discharge port and affect the discharge efficiency. Summary of the Invention
[0004] Based on this, the purpose of this utility model is to provide a barrel-type premixer for processing animal formula milk powder, so as to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a barrel-type premixer for processing animal formula milk powder, comprising a mixing barrel, a hydraulic rod mounted on the top of the mixing barrel via a mounting bracket, a movable plate fixed to the output end of the hydraulic rod, a stirring shaft mounted on the bottom of the movable plate, and the stirring shaft slidably connected to the mixing barrel, the outer surface of the stirring shaft being respectively provided with driven conical teeth and stirring blades, a toothed rod provided at the bottom of the mounting bracket, a sliding rod fixed to the inner side of the mounting bracket, and the movable plate slidingly engaging with the sliding rod, a fixed plate provided on one side of the bottom of the movable plate, a connecting shaft mounted on one side of the fixed plate, a rotating gear and a driving conical tooth respectively fixed at both ends of the connecting shaft, and a servo motor mounted on one side of the mixing barrel. The system includes a motor and a threaded cylinder, with the threaded cylinder rotatably connected to a mixing tank. A one-way lead screw is threaded internally onto the threaded cylinder, and a scraper ring is fixed to the bottom end of the lead screw. A brush is located on the inner side of the scraper ring. A drive shaft is mounted on one side of the mixing tank, and a driven gear is fixed to the top end of the drive shaft. A transmission gear is located on the outer surface of the threaded cylinder. A drive gear is connected to the output end of the motor. An eccentric wheel is fixed to the bottom end of the drive shaft. A support plate is fixed to the bottom of the mixing tank. A movable rod is slidably connected to one side of the support plate. An impact ball is fixed to one end of the movable rod, and springs are fixed to both the top and bottom of the movable rod. A force-bearing plate is fixed to the other end of the movable rod. The drive gear is connected to the output end of the servo motor.
[0006] Furthermore, a feeding port is provided on the other side of the top of the mixing tank, and a discharge port runs through the middle of the bottom of the mixing tank, with a valve provided on the outer surface of the discharge port.
[0007] By adopting the above technical solution, milk powder can be easily added to the mixing tank through the feeding port. After mixing is completed, the staff opens the valve and the milk powder is discharged from the discharge port.
[0008] Furthermore, a guide block is provided at the bottom of the interior of the mixing tank, and the top of the guide block is inclined towards the discharge port.
[0009] By adopting the above technical solution, the milk powder can be discharged more cleanly and thoroughly under the action of the guide block.
[0010] Furthermore, the outer surface of the mixing tank is provided with an observation window, which is made of tempered glass.
[0011] By adopting the above technical solution, staff can observe the mixing process in the mixing tank at any time through the observation window in order to keep track of the processing progress.
[0012] Furthermore, a control panel is installed above the outer surface of the mixing tank, and the servo motor and hydraulic rod are both electrically connected to the control panel.
[0013] By adopting the above technical solution, staff can control the servo motor and hydraulic rod through the control panel.
[0014] Furthermore, the stirring blades are provided in several groups, and the outer surface of the several groups of stirring blades is perforated with multiple through holes.
[0015] By adopting the above technical solution, several sets of stirring blades can fully stir the milk powder raw materials, and the through holes reduce the resistance when the stirring blades rotate, making the stirring blades rotate more smoothly.
[0016] Furthermore, the driving gear meshes with the transmission gear, and the transmission gear meshes with the driven gear.
[0017] By adopting the above technical solution, the rotation of the driving gear can drive the rotation of the transmission gear, and the rotation of the transmission gear can cause the driven gear to rotate.
[0018] Furthermore, the rotating gear meshes with the rack, and the driving bevel gear meshes with the driven bevel gear.
[0019] By adopting the above technical solution, when the rotating gear moves up and down, it will rotate under the cooperation of the rack, which will cause the connecting shaft to drive the active bevel gear to rotate. The rotation of the active bevel gear can cause the driven bevel gear to rotate.
[0020] Furthermore, a base plate is fixed to the bottom of the support plate, and a rubber pad is provided at the bottom of the base plate.
[0021] By adopting the above technical solution, the bottom plate increases the contact area between the mixing tank and the ground, and the rubber pad can increase the friction between the bottom plate and the ground, thereby making the mixing tank more stable.
[0022] Furthermore, the outer surface of the scraper ring is surrounded by a rubber layer, and the rubber layer is in contact with the inner wall of the mixing tank.
[0023] By adopting the above technical solution, the rubber layer can make closer contact with the barrel wall, and the milk powder can be cleaned more thoroughly.
[0024] In summary, the present invention has the following main advantages:
[0025] 1. This utility model comprises a drive shaft, a servo motor, a drive gear, a transmission gear, a driven gear, a connecting wheel, a threaded cylinder, a one-way screw, a scraper ring, a brush, a spring, a movable rod, an eccentric wheel, a force plate, and an impact ball. After the milk powder is stirred, the operator opens the valve on the discharge port and starts the servo motor. The servo motor's electric rotation causes the drive gear to rotate, which in turn causes the transmission gear to drive the threaded cylinder and the driven gear to rotate. The rotation of the threaded cylinder causes the one-way screw to move the scraper ring downwards. The scraper ring can scrape off the milk powder remaining on the bucket wall, while the brush can clean the milk powder on the stirring shaft and stirring blades, thus avoiding milk powder residue and waste. Compared to traditional scrapers installed on mixing mechanisms, the scraper ring of this invention only rubs against the inner wall of the mixing tank during discharge, which can significantly reduce the wear rate of the scraper ring. At the same time, the rotation of the driven gear can cause the transmission shaft to drive the eccentric wheel to rotate. When the eccentric wheel rotates, it can squeeze the force plate, thereby causing the movable rod to pull the impact ball to move to one side. The spring contracts and stores force. When the eccentric wheel is no longer in contact with the force plate, the spring quickly returns to its original state, which in turn causes the movable rod to drive the impact ball to impact the discharge port. This continuous impact on the discharge port can loosen the milk powder that is squeezed together, avoid the phenomenon of blockage in the discharge port during discharge, and improve the discharge efficiency.
[0026] 2. This utility model, by incorporating a hydraulic rod, a gear rack, a rotating gear, a connecting shaft, and a driving bevel gear and a driven bevel gear, allows for the mixing of milk powder and additives. When mixing, the hydraulic rod drives the movable plate to move up and down, causing the rotating gear to rotate on the gear rack. Simultaneously, the connecting shaft drives the driving bevel gear to rotate. The rotation of the driving bevel gear causes the driven bevel gear to rotate, which in turn drives the mixing shaft to rotate. This process stirs the milk powder, and by driving the mixing shaft to move up and down, the mixing blades can stir milk powder of different thicknesses, resulting in more uniform and thorough mixing of the milk powder and additives, thus improving mixing efficiency.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0034] The embodiments of this utility model will be described below based on its overall structure.
[0035] Example 1: A barrel-type premixer for processing animal formula milk powder, as shown in Figures 1-5, includes a mixing barrel 1. A feeding port 2 is provided on the other side of the top of the mixing barrel 1. A discharge port 19 extends through the center of the bottom of the mixing barrel 1, and a valve is provided on the outer surface of the discharge port 19. Milk powder raw materials are easily added to the mixing barrel 1 through the feeding port 2. After mixing, the operator opens the valve, and the milk powder is discharged from the discharge port 19. A hydraulic rod 8 is mounted on the top of the mixing barrel 1 via a mounting bracket 3. A movable plate 10 is fixed to the output end of the hydraulic rod 8. A stirring shaft 13 is mounted on the bottom of the movable plate 10, and the stirring shaft 13 is slidably connected to the mixing barrel 1. The outer surface of the stirring shaft 13 is respectively provided with driven conical teeth 34 and stirring... The mixing blade 21 has several sets, and the outer surface of each set of mixing blades 21 has multiple through holes. These sets of mixing blades 21 can fully mix the milk powder raw materials, and the through holes reduce the resistance during rotation, making the rotation smoother. The bottom of the mounting frame 3 has a toothed rod 9, and the inner side of the mounting frame 3 is fixed with a sliding rod 11. With the positioning and cooperation of the sliding rod 11, the vertical displacement of the movable plate 10 can be more stable, and the movable plate 10 slides in cooperation with the sliding rod 11. A fixed plate 12 is provided on one side of the bottom of the movable plate 10, and a connecting shaft 24 is installed on one side of the fixed plate 12. A rotating gear 25 and a driving bevel gear 26 are respectively fixed at both ends of the connecting shaft 24. 25 meshes with rack 9, and the driving bevel gear 26 meshes with driven bevel gear 34. When the rotating gear 25 moves up and down, it will rotate under the cooperation of rack 9, which will cause the connecting shaft 24 to drive the driving bevel gear 26 to rotate. The rotation of the driving bevel gear 26 can cause the driven bevel gear 34 to rotate. A servo motor 4 and a threaded cylinder 5 are respectively installed on one side of the mixing tank 1, and the threaded cylinder 5 is rotatably connected to the mixing tank 1. A one-way screw 6 is threaded inside the threaded cylinder 5. A scraper ring 22 is fixed at the bottom end of the one-way screw 6, and a brush 23 is provided on the inner side of the scraper ring 22. A drive shaft 7 is installed on one side of the mixing tank 1. A driven gear 33 is fixed at the top end of the drive shaft 7. The outer surface of the threaded cylinder 5 is provided with The system includes a transmission gear 32, a drive gear 31 connected to the output end of the motor, an eccentric wheel 28 fixed to the bottom end of the transmission shaft 7, a support plate 16 fixed to the bottom of the mixing tank 1, a movable rod 18 slidably connected to one side of the support plate 16, an impact ball 30 fixed to one end of the movable rod 18, and springs 29 fixed to both the top and bottom of the movable rod 18. A force plate 27 is fixed to the other end of the movable rod 18. The drive gear 31 is connected to the output end of the servo motor 4. The drive gear 31 meshes with the transmission gear 32, and the transmission gear 32 meshes with the driven gear 33. The rotation of the drive gear 31 can drive the transmission gear 32 to rotate, and the rotation of the transmission gear 32 can cause the driven gear 33 to rotate.
[0036] Referring to Figure 1, in the above embodiment, the outer surface of the mixing tank 1 is provided with an observation window 15, and the observation window 15 is made of tempered glass. The staff can observe the mixing situation inside the mixing tank 1 at any time through the observation window 15 so as to grasp the processing progress.
[0037] Referring to Figure 1, in the above embodiment, a control panel 14 is installed above the outer surface of the mixing tank 1. The servo motor 4 and the hydraulic rod 8 are both electrically connected to the control panel 14. The operator can control the servo motor 4 and the hydraulic rod 8 through the control panel 14.
[0038] Referring to Figures 1 and 2, in the above embodiment, the bottom of the support plate 16 is fixed with a base plate 17, and the bottom of the base plate 17 is provided with a rubber pad. The base plate 17 increases the contact area between the mixing tank 1 and the ground, and the rubber pad can increase the friction between the base plate 17 and the ground, thereby making the mixing tank 1 more stable.
[0039] Referring to Figures 2 and 3, in the above embodiment, the outer surface of the scraper ring 22 is surrounded by a rubber layer, and the rubber layer is in contact with the inner wall of the mixing tank 1. The rubber layer can make closer contact with the tank wall and clean the milk powder more thoroughly.
[0040] Example 2: In order to make the milk powder discharge faster and more thorough, Example 2 is an improvement on Example 1. Referring to Figure 2, a guide block 20 is provided at the bottom of the interior of the mixing tank 1, and the top of the guide block 20 is inclined towards the discharge port 19. Under the action of the guide block 20, the milk powder can be discharged more cleanly and thoroughly.
[0041] The implementation principle of this utility model is as follows: First, the staff adds the milk powder raw materials and additives into the mixing tank 1, and then starts the hydraulic rod 8. The hydraulic rod 8 drives the movable plate 10 to move up and down to reset, thereby causing the rotating gear 25 to rotate on the rack 9. At the same time, the connecting shaft 24 drives the active bevel gear 26 to rotate. The rotation of the active bevel gear 26 causes the driven bevel gear 34 to drive the mixing shaft 13 to rotate. The mixing shaft 13 causes the mixing blade 21 to rotate, thus stirring the milk powder. Furthermore, by driving the mixing shaft 13 to move up and down to reset, the mixing blade 21 can stir milk powder of different thicknesses, making the milk powder more even and thorough. After the milk powder is stirred, the staff opens the valve on the discharge port 19 and then starts the servo motor 4. The servo motor rotates, causing the active gear 31 to rotate, which in turn causes the transmission gear 32 to drive the threaded cylinder 5 and the driven gear 33 to rotate. After the threaded cylinder 5 rotates, the one-way screw 6 drives the scraper ring 22 downward. The scraper ring 22 can scrape off the milk powder residue on the bucket wall, while the brush 23 can clean the milk powder on the stirring shaft 13 and stirring blade 21, thus avoiding milk powder residue and waste. Compared with the traditional scraper installed on the stirring mechanism, the scraper ring 22 of this utility model only rubs against the inner wall of the stirring bucket 1 when discharging, which can greatly reduce the wear rate of the scraper ring 22. At the same time, the rotation of the driven gear 33 can cause the transmission shaft 7 to drive the eccentric wheel 28 to rotate. When the eccentric wheel 28 rotates, it can squeeze the force plate 27, thereby causing the movable rod 18 to pull the impact ball 30 to move to one side. The spring 29 contracts and stores force. When the eccentric wheel 28 is not in contact with the force plate 27, the spring 29 quickly returns to its original state, thereby causing the movable rod 18 to drive the impact ball 30 to impact the discharge port 19. This continuous impact on the discharge port 19 can loosen the milk powder that is squeezed together, avoiding the phenomenon of blockage of the discharge port 19 during discharge.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
