DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-5 This application is described in further detail.

[0030] The embodiment of the present application discloses an anti-clogging powder filling machine for lactose production.

[0032] The placing table 3 includes a bottom plate 31 and an upper plate 32, and a damping spring 33 is arranged between the bottom plate 31 and the upper plate 32. When filling starts, the packaging bag 4 is located at the top. As the powder in the packaging bag 4 increases, the supporting force of the packaging bag 4 to overcome the damping spring 33 gradually decreases.

[0033] The feed hopper 2 is conical, and the bottom of the feed hopper 2 is connected to a straight cylindrical discharge pipe 21 and a telescopic tube 22. The telescopic tube 22 is arranged outside the discharge pipe 21, and a hook 221 is arranged on the outer wall of the telescopic tube 22. The top of the packaging bag 4 is provided with a straight cylindrical feed bag 41 and a sling 42 for hanging. The feed bag 41 is tied to the discharge pipe 21 by a binding rope, and the sling 42 is hung on the hook 221.

[0034] Reference Figure 2-4 A scraper rod 5 is rotatably arranged in the discharge pipe 21, a scraper 51 is arranged between the scraper rod 5 and the discharge pipe 21, the scraper 51 abuts against the inner peripheral wall of the discharge pipe 21, a waste collecting bowl 52 is arranged below the scraper 51, the waste collecting bowl 52 is detachably connected to the scraper rod 5 by a connecting bolt, a connecting plate 521 is arranged on the waste collecting bowl 52, a connecting column 522 is fixedly connected to the bottom end of the scraper rod 5, one end of the connecting plate 521 is annular and sleeved on the connecting column 522, and the connecting bolt passes through the connecting plate 521 and the connecting column 522 and is threadedly connected with a connecting nut to fix the waste collecting bowl 52. The bottom end of the scraper rod 5 extends to the bottom of the discharge pipe 21, and a poking rod 6 is arranged on the scraper rod 5, and the poking rod 6 is telescopically arranged.

[0035] The scraper rod 5 is provided with a fixing bolt, which passes through the scraper rod 5 and the scraper 51 and is threadedly connected with a fixing nut, thereby fixing the scraper 51 .

[0036] When filling powder, the scraper 51 on the scraper rod 5 scrapes the powder attached to the inner wall of the discharge pipe 21 along the inner wall of the discharge pipe 21 and drops it into the waste collecting bowl 52, so that the powder on the inner wall of the discharge pipe 21 is cleaned in time, and the poking rod 6 on the scraper rod 5 pokes and disperses the powder that may be gathered together when it is extended and retracted, thereby improving the smoothness of the powder falling and improving the filling efficiency.

[0037] Reference Figure 2-5The poking rod 6 includes an outer rod 61 and an inner rod 62, both ends of the outer rod 61 pass through the scraper rod 5 and are fixedly connected to the scraper rod 5, the inner rod 62 is slidably connected to the outer rod 61, and one end of the inner rod 62 close to the central axis of the discharge pipe 21 passes through the outer rod 61, and a receiving groove 611 for the extension and retraction of the inner rod 62 is provided in the outer rod 61, and a compression spring 63 is provided in the receiving groove 611, one end of the compression spring 63 is fixedly connected to the inner wall of the receiving groove 611, and the other end of the compression spring 63 is fixedly connected to the inner rod 62, and the compression spring 63 applies a force to the inner rod 62 to extend the inner rod 62 toward the outside of the outer rod 61, and the end of the inner rod 62 away from the central axis of the discharge pipe 21 is provided with a pulling component for intermittently pulling the inner rod 62 in a direction away from the central axis of the discharge pipe 21.

[0038] The pulling assembly includes a traction rope 64 and a guide block 65. One end of the traction rope 64 is fixedly connected to the inner rod 62. The other end of the traction rope 64 is rotatably connected to the outer wall of the discharge pipe 21 after passing the guide block 65. The traction rope 64 is kept in a tensioned state. The side of the guide block 65 away from the discharge pipe 21 is in an arc shape. There are multiple guide blocks 65 arranged along the circumference of the discharge pipe 21. A dovetail block 66 is arranged above the guide block 65. One end of the traction rope 64 away from the inner rod 62 is fixedly connected to the dovetail block 66. An annular dovetail groove 67 is provided on the outer peripheral wall of the discharge pipe 21. The dovetail block 66 slides in the dovetail groove 67. The position where the feed bag 41 and the discharge pipe 21 are tied is above the dovetail groove 67 to prevent the feed bag 41 and the discharge pipe 21 from being tied tightly to hinder the movement of the traction rope 64.

[0039] During the rotation of the scraper rod 5, the traction rope 64 passes through the guide block 65 at intervals. When the traction rope 64 passes through the guide block 65, the traction rope 64 pulls the inner rod 62 in the direction away from the central axis of the discharge pipe 21. When the traction rope 64 does not pass through the guide block 65, the compression spring 63 pulls the inner rod 62 in the direction close to the central axis of the discharge pipe 21, thereby causing the poking rod 6 to reciprocate and extend.

[0040] The poking rod 6 is tilted, and in this embodiment, the angle between the axis of the poking rod 6 and the horizontal plane is 45°, and the end of the poking rod 6 close to the central axis of the discharge pipe 21 is the highest end of the poking rod 6. The tilted setting makes the poking rod 6 more effective in poking and dispersing the powder when it is extended and retracted.

[0041] The inner rod 62 is provided with a poking needle 621 at one end close to the central axis of the discharge tube 21. A plurality of poking needles 621 are evenly arranged on the end surface of the poking rod 6. When the inner rod 62 is extended or retracted, the poking needles 621 come into contact with the powder. Since the poking needles 621 are thin and distributed in a plurality, some small powder lumps can be poked out.

[0042] Reference Figure 2A stirring assembly 7 is provided in the feed hopper 2, and the stirring assembly 7 includes a stirring rod 71, on which a stirring blade 72 is provided. The stirring rod 71 rotates at the center of the feed hopper 2, and the stirring rod 71 is connected to the scraper rod 5 by a connecting rod 73. When the stirring rod 71 rotates, it drives the scraper rod 5 to rotate along the circumferential direction of the discharge pipe 21.

[0043] Reference Figure 2 The top surface of the feeding hopper 2 is sealed by a sealing plate 23. A feeding pipe 8 is provided on the top surface of the feeding hopper 2 to connect with the feeding mechanism. The feeding pipe 8 penetrates into the sealing plate 23. The feeding pipe 8 is located on one side of the radial direction of the feeding hopper 2. The plane where the blades of the stirring blade 72 are located intersects with the vertical plane. The setting of the sealing plate improves the sealing performance of the feeding hopper and reduces the possibility of dust contaminating the powder during the feeding process.

[0044] The top end of the stirring rod 71 extends out of the sealing plate 23 and is rotatably connected to the sealing plate 23 . A bearing that cooperates with the stirring rod 71 for rotation is provided on the top surface of the sealing plate 23 .

[0045] The feeding hopper 2 includes an outer cylinder 24 and an inner cylinder 25. The sealing plate 23 is fixedly connected to the outer cylinder 24 and the inner cylinder 25 at the same time. The powder enters the inner cylinder 25 from the feeding pipe 8. An air inlet chamber 26 is arranged between the outer cylinder 24 and the inner cylinder 25. The air inlet chamber 26 is located on the side of the feeding hopper 2 where the feeding pipe 8 is radially arranged. An air jet hole 251 communicating with the air inlet chamber 26 is opened on the side wall of the inner cylinder 25. An air inlet pipe 231 is arranged on the sealing plate 23. The air inlet pipe 231 is connected to an external high-pressure air source through a pulse solenoid valve. The high-pressure air source enters the inner cylinder 25 through the air jet hole 251 and blows the powder. The air jet hole 251 is located above the stirring blade 72 and is arranged downward. The airflow ejected from the air jet hole 251 contacts the stirring blade 72 and drives the stirring blade 72 to rotate. The powder falls from the feeding pipe 8 to contact the stirring blade 72 and assists in driving the stirring blade 72 to rotate.

[0046] The high-pressure air source is sprayed into the inner cylinder 25 through the pulse solenoid valve, and is sprayed towards the powder to disperse the powder. At the same time, the air flow ejected from the air jet hole 251 contacts the stirring blade 72 and drives the stirring blade 72 to rotate, which not only further disperses the powder, but also provides power to the stirring blade 72. The impact of the powder on the stirring blade 72 provides auxiliary power. The impact of the high-pressure air source on the stirring blade 72 and the impact of the powder on the stirring blade 72 enable the stirring rod 71 to keep rotating during the filling process, without the need for a driving source such as a motor, thereby saving energy.

[0047] The implementation principle of the anti-clogging powder filling machine for lactose production in the embodiment of the present application is: The feeding mechanism conveys the powder to the inner cylinder 25 through the feeding pipe 8, and the high-pressure gas source drives the stirring blade 72 to rotate, drives the stirring rod 71 to rotate, drives the scraping rod 5 to rotate, and the scraping rod 5 scrapes the powder attached to the inner wall of the discharge pipe 21 into the waste collecting bowl 52 through the scraper 51. After the waste collecting bowl 52 is removed, the waste can be poured out; The stirring rod 71 rotates, the stirring blade 72 rotates and cooperates with the jet to stir the powder, and the poking rod 6 is extended and retracted to further break up the powder at the outlet of the discharge pipe 21, thereby improving the smoothness of the powder flow.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
