Technical Field

[0001] This invention belongs to the field of filling machine technology, and particularly relates to a soft film powder filling machine with automatic powder extraction function. Background Technology

[0002] A soft film powder filling machine is an automated or semi-automated device specifically designed to accurately and efficiently fill soft film powder (a powdered product commonly used in the beauty and skincare industry, which needs to be mixed with water before use) into various packaging containers (such as cans, bags, bottles, etc.).

[0003] Existing soft film powder filling machines generally require manual addition of powder into the funnel during use. However, due to the fast filling speed of existing soft film powder filling machines, powder needs to be added frequently, which makes the work tiring for workers and generates a lot of dust. Even when wearing masks, dust can still enter the mouth and nose, posing a potential health hazard to workers.

[0004] Therefore, it is necessary to invent a soft film powder filling machine with automatic powder extraction function to solve the above problems. Summary of the Invention

The movable sleeve is slidably sleeved on the drive shaft, and a reset component is provided at the bottom end of the movable sleeve. The auger blades are evenly connected to the surface of the movable sleeve and are used to convey the soft film powder in the feed pipe downward when the drive shaft drives the movable sleeve to rotate. The grinding mechanism is located at the top of the movable sleeve and is used to crush the soft film powder. The polarization mechanism is located at the bottom of the grinding mechanism and is used to drive the movable sleeve to move in the vertical direction.

[0007] Furthermore, the grinding mechanism includes grinding rollers, a perforated plate, and scrapers. Multiple grinding rollers are evenly distributed in a ring around the outside of the drive shaft. One end of each grinding roller is rotatably connected to the surface of the drive shaft, and the other end of each grinding roller is inclined downwards. The perforated plate is conical, and its diameter gradually decreases from top to bottom.

Multiple scrapers are evenly fixedly connected to the surface of the drive shaft, and their bottom edges are in contact with the top surface of the perforated plate.

[0008] Furthermore, the polarization mechanism includes pull rods, counterweight balls, conical rings, and spherical protrusions. Multiple pull rods are evenly distributed in a ring on the side of the movable sleeve. The top of each pull rod is hinged to the surface of the movable sleeve. The counterweight ball is rotatably connected to the bottom of the pull rod. The conical ring is coaxial with the drive shaft, and its diameter gradually increases from top to bottom, allowing it to contact the counterweight ball. Several connecting rods are fixedly connected between the outer surface of the conical ring and the inner wall of the feed pipe. An annular spherical groove, coaxial with the inner surface of the conical ring, is provided, allowing the counterweight ball to enter the annular spherical groove. Multiple spherical protrusions are evenly fixedly connected within the annular spherical groove.

[0009] Furthermore, the reset component includes a sleeve, a pressure ring, a support ring, and a reset spring. The sleeve is fixedly connected to the bottom end of the movable sleeve, the pressure ring is fixedly connected to the inner wall of the sleeve, the support ring is located at the bottom of the pressure ring and is fixedly sleeved on the drive shaft, and the reset spring is sleeved on the drive shaft, with both ends of the reset spring fixedly connected to the pressure ring and the support ring, respectively.

[0010] Furthermore, both ends of the movable sleeve are fixedly connected to retractable plastic sleeves, which are slidably fitted onto the drive shaft, and the end of the plastic sleeve away from the movable sleeve is tightly fitted together with the surface of the drive shaft.

[0011] Furthermore, a limiting rod is provided near the bottom of the pull rod, and the limiting rod and the pull rod opposite it are located in the same vertical plane. The limiting rod is arc-shaped, and one end of the limiting rod is fixedly connected to the surface of the drive shaft.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] This invention provides, for example Figures 1 to 5The soft film powder filling machine shown includes a filling machine body 1, a feeding hopper 2 connected to the top of the filling machine body 1, a powder extraction device for adding powder connected to the feeding hopper 2, the powder extraction device including a powder extraction machine body 3, a powder suction pipe 5 connected to one side of the powder extraction machine body 3 through a flexible hose 4, a feeding pipe 6 connected to the bottom of the powder extraction machine body 3, a fixing frame 7 detachably connected to the feeding pipe 6, the fixing frame 7 being fixedly connected to the top of the filling machine body 1, and an anti-blocking component provided inside the feeding pipe 6, the anti-blocking component including a drive shaft 8, a movable sleeve 9, an auger blade 10, a grinding mechanism and a polarization mechanism; The drive shaft 8 is located at the center of the feed pipe 6, and the top end of the drive shaft 8 is connected to the rotating shaft of the powder extraction machine body 3. The movable sleeve 9 is slidably sleeved on the drive shaft 8, and a reset component is provided at the bottom end of the movable sleeve 9. The auger blades 10 are evenly connected to the surface of the movable sleeve 9, and are used to convey the soft film powder in the feed pipe 6 downward when the drive shaft 8 drives the movable sleeve 9 to rotate. The grinding mechanism is located at the top of the movable sleeve 9 and is used to crush the soft film powder. The polarization mechanism is located at the bottom of the grinding mechanism and is used to drive the movable sleeve 9 to move in the vertical direction. By setting up a powder extraction machine body 3, during the use of the filling machine body 1, the powder extraction machine body 3 can be installed on the feeding hopper 2, and then the powder suction pipe 5 is inserted into the raw material bucket of soft film powder. Subsequently, as the powder extraction machine body 3 is started, the powder extraction machine body 3 can suck the soft film powder in the raw material bucket of soft film powder into the feeding hopper 2 through the flexible hose 4 and the powder suction pipe 5, thereby automatically completing the powder addition operation of the filling machine body 1. Compared with the existing manual powder addition method, it improves the powder addition efficiency, reduces the amount of manual labor, and avoids the harm of soft film powder to the workers' bodies during long-term powder addition. Furthermore, by installing an anti-clogging component in the feed pipe 6, the grinding mechanism can crush the soft film powder entering the feed pipe 6 during the operation of the powder suction machine body 3, thereby preventing the feed pipe 6 from being blocked due to clumps of soft film powder entering the feed pipe 6. At the same time, the auger blades 10 can accelerate the downward conveying of the soft film powder in the feed pipe 6 under the drive of the drive shaft 8. The deflection mechanism can also work with the movable sleeve 9 and the reset component to make the auger blades 10 move back and forth in the vertical direction, thereby further discharging the soft film powder smoothly from the feed pipe 6, preventing the soft film powder from blocking the feed pipe 6, and ensuring the normal operation of the powder suction machine body.

[0020] like Figure 2 and Figure 3As shown, the grinding mechanism includes grinding rollers 11, a perforated plate 12, and a scraper 13. Multiple grinding rollers 11 are evenly distributed in a ring around the outside of the drive shaft 8. One end of each grinding roller 11 is rotatably connected to the surface of the drive shaft 8, while the other end of each roller is inclined downwards. The perforated plate 12 is conical, with its diameter gradually decreasing from top to bottom. The perforated plate 12 is rotatably sleeved on the drive shaft 8, and its top surface is in contact with the grinding rollers 11. Several fixing blocks 14 are evenly fixed between the bottom edge of the perforated plate 12 and the inner wall of the feed pipe 6. The scraper... There are multiple scrapers 13, which are evenly fixedly connected to the surface of the drive shaft 8. The bottom edge of the scraper 13 is in contact with the top surface of the hollow plate 12. The top surface of the fixing block 14 is smoothly connected to the top surface of the hollow plate 12, and the scraper 13 can contact the top surface of the fixing block 14. The top of the multiple grinding rollers 11 is provided with the same guide shroud 27. The guide shroud 27 is a cone shape that is wider at the top and narrower at the bottom. The guide shroud 27 is sleeved on the outside of the drive shaft 8, and the bottom end of the guide shroud 27 is close to the top end of the grinding roller 11. The top edge of the guide shroud 27 is detachably connected to the inner wall of the feed pipe 6. During the operation of the powder extraction machine body 3, the soft film powder may clump. Therefore, when the clumped soft film powder enters the feed pipe 6, it may cause blockage. At this time, a grinding mechanism is provided. During the rotation of the drive shaft 8, the grinding roller 11 can roll along the top of the perforated plate 12 under the drive of the drive shaft 8. During this process, when the soft film powder enters the feed pipe 6, it can fall into the grinding pipe near the top under the guidance of the guide shroud 27. Then, when the soft film powder falls on the perforated plate 12, the grinding roller 11 can cooperate with the perforated plate 12 to crush the soft film powder, thereby crushing the clumped soft film powder. The crushed soft film powder can then pass through the perforated plate 12 or fall into the area where the auger blade 10 is located through the bottom edge of the perforated plate 12, thereby avoiding the problem of the feed pipe 6 being blocked due to the clumping of soft film powder. At the same time, as the drive shaft 8 drives the grinding roller 11 to move, the scraper 13 can also scrape against the top of the perforated plate 12 under the drive of the drive shaft 8, thereby accelerating the soft film powder to pass through the gaps of the perforated plate 12 and its bottom edge, thus avoiding the perforated plate 12 from being blocked and also avoiding the accumulation of soft film powder in the top space of the perforated plate 12.

[0021] like Figures 3 to 5As shown, the polarization mechanism includes a pull rod 15, a counterweight ball 16, a conical ring 17, and spherical protrusions 18. There are multiple pull rods 15, which are evenly distributed in a ring on the side of the movable sleeve 9. The top of the pull rod 15 is hinged to the surface of the movable sleeve 9. The counterweight ball 16 is rotatably connected to the bottom of the pull rod 15. The conical ring 17 is coaxial with the drive shaft 8. The diameter of the conical ring 17 gradually increases from top to bottom, and the conical ring 17 can contact the counterweight ball 16. Several connecting rods 19 are fixedly connected between the outer side of the conical ring 17 and the inner wall of the feed pipe 6. An annular spherical groove 20 coaxial with the conical ring 17 is provided on the inner side of the conical ring 17, and the counterweight ball 16 can enter the annular spherical groove 20. There are multiple spherical protrusions 18, which are evenly fixedly connected in the annular spherical groove 20. The reset component includes a sleeve 21, a pressure ring 22, a support ring 23, and a reset spring 24. The sleeve 21 is fixedly connected to the bottom end of the movable sleeve 9. The pressure ring 22 is fixedly connected to the inner wall of the sleeve 21. The support ring 23 is located at the bottom of the pressure ring 22 and is fixedly sleeved on the drive shaft 8. The reset spring 24 is sleeved on the drive shaft 8, and both ends of the reset spring 24 are fixedly connected to the pressure ring 22 and the support ring 23, respectively. The outer diameter of the support ring 23 matches the inner diameter of the sleeve 21, and the support ring 23 can always be located inside the sleeve 21. When the powder is added to the feed hopper 2 by the powder extraction machine body 3, the counterweight ball 16 and the pull rod 15 can deflect away from the drive shaft 8 under the action of centrifugal force as the drive shaft 8 rotates. As the counterweight ball 16 and the pull rod 15 deflect, when the counterweight ball 16 contacts the conical ring 17, the counterweight ball 16 can be inserted into the annular spherical groove 20. As the drive shaft 8 drives the movable sleeve 9 to rotate, the counterweight ball 16 can roll along the spherical groove. During this process, when the counterweight ball 16 contacts the spherical protrusion 18, the counterweight ball 16 can pull the pull rod 15 downward under the pushing action of the spherical protrusion 18. As the pull rod 15 moves downward, the movable sleeve 9 can drive the winch... While the auger blade 10 rotates, the movable sleeve 9 can also drive the auger blade 10 to move vertically. During this process, the return spring 24 can be gradually compressed under the pressure of the pressure ring 22. When the counterweight ball 16 separates from the spherical protrusion 18, the movable sleeve 9 can be reset upward under the support of the return spring 24. Since there are many spherical protrusions 18, the movable sleeve 9 can drive the auger blade 10 to move back and forth vertically at a high frequency during the process of the counterweight ball 16 contacting multiple spherical protrusions 18 in sequence. This allows the soft film powder in the feed pipe 6 to be moved out of the feed pipe 6 more quickly under the action of the auger blade 10, avoiding blockage of the soft film powder in the feed pipe 6.

[0022] like Figure 4 and Figure 5As shown, both ends of the movable sleeve 9 are fixedly connected with retractable plastic sleeves 25. The plastic sleeves 25 are slidably sleeved on the drive shaft 8, and the end of the plastic sleeve 25 away from the movable sleeve 9 is tightly sleeved with the surface of the drive shaft 8. By providing a plastic sleeve 25, the plastic sleeve 25 can adaptively extend or shorten as the movable sleeve 9 moves vertically, thus not affecting the movement of the movable sleeve 9. In addition, the plastic sleeve 25 can also seal both ends of the movable sleeve 9, thereby preventing the soft film powder from entering the inside of the movable sleeve 9 through both ends and causing the movement of the movable sleeve 9 to be obstructed.

[0023] like Figure 3 and Figure 4 As shown, a limiting rod 26 is provided near the bottom of the pull rod 15, and the limiting rod 26 and the pull rod 15 opposite it are located in the same vertical plane. The limiting rod 26 is arc-shaped, and one end of the limiting rod 26 is fixedly connected to the surface of the drive shaft 8. The limiting rod 26 has a slot that matches its length in the vertical direction, and the pull rod 15 is locked in the slot near the bottom. By setting a limit rod 26, when the pull rod 15 and the counterweight ball 16 deflect away from the drive shaft 8 under the action of centrifugal force, the pull rod 15 will also be subjected to a torsional force perpendicular to its direction of movement. Therefore, during long-term use, the hinge between the pull rod 15 and the drive shaft 8 may become loose. The presence of the limit rod 26 can support and restrict the pull rod 15, preventing the torsional force on the pull rod 15 during movement from damaging its connection.

[0024] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
