A sleeve filling mechanism

Abstract

This utility model discloses a packaging filling mechanism, belonging to the field of powder filling. The device includes a hopper located at the outlet of a powder tank, a rotating drive ring at the bottom of the hopper, a rotating guide ring at the bottom of the drive ring, and a sliding push rod and a push block at the bottom of the hopper. The push block keeps the guide ring stationary relative to the hopper, while the sliding of the push rod, via a drive assembly, drives the drive ring to rotate. When the powder inside the packaging is nearly full, the powder causes the push block to slide into the hopper, causing the guide ring to rotate. An angle is formed between the guide ring and the hopper, guiding the powder towards the edge of the packaging. The rotating drive ring alters the sliding path of the powder during filling, causing the powder to slide towards the edge of the packaging. When filling at the top of the packaging, the powder fills from the inner wall of the packaging towards the filling port, filling the inner wall first, thus quickly completing the powder filling of the packaging.

Description

Technical Field

[0001] This utility model relates to the field of powder filling, and in particular to a packaging filling mechanism. Background Technology

[0002] Some flat, large sheet materials are processed by making the sheet into a tube shape, with a filling port at one end. Powder is filled into the filling port through a powder tank and pipes, and then the powder is burned into a liquid. After the liquid solidifies, the end of the sheet is welded to seal it, thus completing the manufacturing of the sheet. The tubular sheet is called a cladding.

[0003] The filling sleeves come in square, round, and other shapes. Existing systems use lifting filling valves or rotary filling mechanisms to fill the sleeves with powder. However, because the filling port is located at the end, the powder can flow relatively smoothly to the sides during the initial filling stage. As the filling volume increases, the flow of powder within the container becomes more restricted; especially near the filling port, the powder flow is obstructed, and the powder inside the filling port cannot quickly diffuse to the sides, resulting in a small space at the top of the sleeve that is difficult to fill completely.

[0004] In summary, when filling powder with a packaged filling mechanism in the prior art, the fixed position of the filling port makes it difficult to quickly fill the space at the top of the package when it is nearly full. Utility Model Content

[0005] This utility model provides a sleeve filling mechanism, which can solve the problem that when the existing sleeve filling mechanism is used for powder filling, it is difficult to quickly fill the space at the top of the sleeve when it is close to being full because the filling port position is fixed.

[0006] A packaging filling mechanism includes a hopper for guiding powder filling. The hopper is fixedly installed at the outlet of a powder tank by a fixing component. A guiding mechanism is provided inside the hopper, and the guiding mechanism includes: A drive ring is rotatably set at the bottom of the hopper. A guide ring is rotatably connected to the bottom of the drive ring. Several guide blocks are rotatably connected inside the guide ring. The several guide blocks are arranged in a ring array inside the guide ring. A push rod is slidably disposed inside the hopper. A drive assembly for transmission is provided between the push rod and the drive ring. A push block is fixedly connected to the end of the push rod. A positioning assembly for limiting the rotation of the guide ring is provided between the guide ring and the push block. The guide block is slidably connected to the push block.

[0007] Optionally, the surface of the push block is provided with a plurality of through grooves, and the plurality of through grooves are evenly distributed on the surface of the push block.

[0008] Optionally, a raised ring is fixedly connected to the surface of the push block, the edge of the raised ring coincides with the edge of the push block, the cross-section of the raised ring is arc-shaped, and the projection of the raised ring toward the push block is located on the surface of the push block.

[0009] Optionally, the guide block has a sliding groove on its surface, and the push block has a sliding shaft fixedly connected to its surface. The sliding shaft is adapted to the sliding groove, and the cross-section of the sliding shaft is T-shaped.

[0010] Optionally, the fixing component includes several fixing rods rotatably disposed inside the powder tank, and the surface of the hopper is provided with an annular groove and several fixing grooves, all of which are connected to the annular groove, and the fixing rods are adapted to the fixing grooves.

[0011] Optionally, the drive assembly includes a plurality of contact rings fixedly disposed on the surface of the push rod, the plurality of contact rings being arranged in a ring array on the surface of the push rod, the contact rings being alternately disposed with guide rings, and the contact rings being threadedly connected to the drive ring.

[0012] Optionally, a movable rod is fixedly connected inside the hopper, and a movable groove is formed on the surface of the push rod. The movable rod is adapted to the movable groove. A vertical groove is formed on the surface of the movable rod, and a vertical shaft is fixedly connected inside the movable groove. The vertical shaft is adapted to the vertical groove.

[0013] Optionally, a connecting spring is fixedly connected between the moving rod and the pushing rod.

[0014] Optionally, the positioning component includes a plurality of sliding blocks fixedly disposed on the surface of the guide ring, the sliding blocks being spaced apart from the guide ring, and a plurality of positioning grooves being formed on the surface of the pushing block, the positioning grooves being adapted to the sliding blocks.

[0016] This utility model provides a packaging filling mechanism, including a hopper located at the outlet of a powder tank. A rotating drive ring is located at the bottom of the hopper, and a rotating guide ring is located at the bottom of the drive ring. A sliding push rod and a push block are located at the bottom of the hopper. The push block keeps the guide ring stationary relative to the hopper. Simultaneously, the sliding of the push rod can drive the drive ring to rotate through a drive assembly. When the powder inside the packaging is nearly full, the amount of powder continuously increases, causing the push block to slide into the hopper, which in turn causes the guide ring to rotate. An angle is formed between the guide ring, the push block, and the hopper. At this time, some powder tends to fill from the surface of the guide ring into the packaging. The guide ring guides the powder to slide towards the edge area of ​​the packaging. The drive ring rotates when the push block slides, which changes the sliding path of the powder during filling. This causes the powder to slide out of the guide ring at a certain angle towards the edge of the packaging. When filling at the top of the packaging, the powder fills from the inner wall of the packaging towards the filling port. The inner wall is filled first, which can quickly complete the powder filling of the packaging. Attached Figure Description

[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0020] like Figures 1 to 4As shown in the figure, an embodiment of the present invention provides a packaging filling mechanism, including a feeding hopper 1 for guiding powder filling. The feeding hopper 1 is fixedly installed at the outlet of the powder tank by a fixing component. A guiding mechanism is provided inside the feeding hopper 1, and the guiding mechanism includes: A drive ring 21 is rotatably set at the bottom of the hopper 1. A guide ring 22 is rotatably connected to the bottom of the drive ring 21. A plurality of guide blocks 23 are rotatably connected inside the guide ring 22. The plurality of guide blocks 23 are arranged in a ring array inside the guide ring 22. A push rod 24 is slidably disposed inside the hopper 1. A drive assembly for transmission is provided between the push rod 24 and the drive ring 21. A push block 25 is fixedly connected to the end of the push rod 24. A positioning assembly for limiting the rotation of the guide ring 22 is provided between the guide ring 22 and the push block 25. The guide block 23 is slidably connected to the push block 25. In summary, the packaging filling mechanism provided by this utility model includes a hopper 1 located at the outlet of a powder tank. A rotating drive ring 21 is located at the bottom of the hopper 1, and a rotating guide ring 22 is located at the bottom of the drive ring 21. A sliding push rod 24 and a push block 25 are also located at the bottom of the hopper 1. The push block 25 keeps the guide ring 22 stationary relative to the hopper 1. Simultaneously, the sliding of the push rod 24, through a drive assembly, can drive the drive ring 21 to rotate. When the powder inside the packaging is nearly full, the amount of powder continuously increases, causing the push block 25 to slide into the hopper 1, thereby facilitating the rotation of the guide ring 22. When ring 22 rotates, an angle is formed between guide ring 22, push block 25, and hopper 1. At this time, some powder tends to fill from the surface of guide ring 22 into the inside of the sleeve. The guide ring 22 guides the powder to slide towards the edge area of ​​the sleeve. The drive ring 21 will rotate when push block 25 slides, which will change the sliding path of the powder during filling. This will cause the powder to slide out of guide ring 22 at a certain angle and slide towards the edge of the sleeve. When filling the top of the sleeve, the powder is filled from the inner wall of the sleeve to the filling port. The inner wall is filled first, which can quickly complete the powder filling of the sleeve. In some specific implementations, the surface of the push block 25 is provided with a plurality of through grooves 31, which are evenly distributed on the surface of the push block 25. A raised ring 32 is fixedly connected to the surface of the push block 25, the edge of the raised ring 32 coincides with the edge of the push block 25, the cross-section of the raised ring 32 is arc-shaped, and the projection of the raised ring 32 toward the push block 25 is all located on the surface of the push block 25. The through grooves 31 are provided so that when the powder slides to the surface of the push block 25, it can flow out along the through grooves 31, avoiding a large area of ​​empty powder below the push block 25 during powder filling, thus forming a valley. The arc-shaped raised ring 32 can prevent the powder from accumulating on the surface of the push block 25 along the edge of the push block 25 when it is close to being full, thus affecting the upward movement of the push block 25. The projection of the raised ring 32 is all located on the surface of the push block 25 and the edges of the two coincide, indicating that the arc length of the raised ring 32 on the side closer to the powder is greater than that on the other side, and the raised ring 32 can prevent the powder from sliding onto the surface of the push block 25. In some specific implementations, the guide block 23 has a sliding groove 34 on its surface, and the push block 25 has a sliding shaft 33 fixedly connected to its surface. The sliding shaft 33 is adapted to the sliding groove 34. The cross-section of the sliding shaft 33 is T-shaped. The connection between the sliding shaft 33 and the sliding groove 34 can prevent the guide block 23 and the push block 25 from separating, thus preventing a large amount of powder from sliding in and remaining in the gap between them. In some specific implementations, the fixing assembly includes several fixing rods 41 rotatably disposed inside the powder tank, and the surface of the hopper 1 is provided with an annular groove 43 and several fixing grooves 42, all of which are connected to the annular groove 43, and the fixing rods 41 are adapted to the fixing grooves 42. In some specific embodiments, the drive assembly includes a plurality of contact rings 51 fixedly disposed on the surface of the push rod 24, the plurality of contact rings 51 being arranged in a ring array on the surface of the push rod 24, the contact rings 51 being alternately disposed with the guide ring 22, and the contact rings 51 being threadedly connected to the drive ring 21; In a further embodiment, a movable rod 52 is fixedly connected inside the hopper 1, and a movable groove 53 is formed on the surface of the push rod 24. The movable rod 52 is adapted to the movable groove 53. A vertical groove is formed on the surface of the movable rod 52, and a vertical shaft is fixedly connected inside the movable groove 53. The vertical shaft is adapted to the vertical groove. Through the adaptation of the vertical shaft and the vertical groove, the push rod 24 is restricted to sliding vertically only on the surface of the movable rod 52. A contact ring 51 is provided that contacts the surface of the drive ring 21, and the contact ring 51 is threadedly connected to the drive ring 21. When the contact ring 51 slides under the action of the push rod 24, the drive ring 21 can be rotated due to the sliding of the push rod 24. In a further embodiment, a connecting spring 54 is fixedly connected between the moving rod 52 and the pushing rod 24; In some specific implementations, the positioning component includes a plurality of sliding blocks 61 fixedly disposed on the surface of the guide ring 22, the sliding blocks 61 being spaced apart from the guide ring 22, and a plurality of positioning grooves 62 being formed on the surface of the push block 25, the positioning grooves 62 being adapted to the sliding blocks 61; by restricting the sliding path of the sliding blocks 61 on the surface of the push block 25, the position of the guide ring 22 is restricted, and since the push block 25 can only slide in the vertical direction, the position of the guide ring 22 is further restricted; In some specific implementations, a plurality of annular rods 63 are fixedly connected to the surface of the guide ring 22, and a rotating groove is formed on the surface of the guide ring 22, the rotating groove being adapted to the annular rods 63; The working principle of this utility model: First, place the hopper 1 at the outlet of the powder tank, corresponding to the positions of the fixing rod 41 and the fixing groove 42. Then, rotate the fixing rod 41 to insert it into the fixing groove 42. Next, place the filling port of the sleeve corresponding to the hopper 1, so that the guide ring 22 is located at the junction of the filling port and the sleeve. Then, fill the sleeve with powder. The powder falls along the surface of the push block 25 into the sleeve. As the powder fills the sleeve, it causes the push block 25 to move upward when it is almost full, causing the guide ring 22 to rotate. The powder continues to fill along the guide ring 22, while the drive ring 21 rotates, changing the local path of the powder's descent. This causes the powder to collide with each other, continuously filling the inner wall of the sleeve. After the inner wall is filled, the powder moves towards the filling port under the action of gravity, filling the filling port.

[0021] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
