Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically a packaging material switching mechanism. Background Technology

[0002] In automated packaging processes in industries such as tea, food, and pharmaceuticals, material weighing and sorting are often required. For example, tea packaging machines are typically equipped with weighing hoppers. When tea weight is detected to be below the set standard (too light or too heavy), it must be intercepted and reprocessed to avoid packaging substandard products. Traditional sorting methods mainly rely on manual sorting or simple mechanical baffles. Therefore, there is an urgent need for a compact, precise, and automatically controllable material switching mechanism to solve the aforementioned technical problems and meet the demands of high-speed, high-precision packaging. Utility Model Content

[0003] This invention provides a packaging material switching mechanism that overcomes the shortcomings described in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A packaging material kicking switching mechanism includes a kicking bin and a drive assembly. The kicking bin is driven to move by the drive assembly. The kicking bin includes a main slope that slopes downward to the right and an L-shaped opening and closing plate. In the initial state, the main slope and the L-shaped opening and closing plate cooperate to form a complete slope. In the open state, the L-shaped opening and closing plate rotates around the connecting rod as the rotation base point. The L-shaped opening and closing plate intercepts and changes the tea conveying path.

[0006] In some implementations, a collection container is also included, located below the L-shaped hinged plate.

[0007] In some embodiments, the drive assembly includes a first motor, a drive pulley, a belt, a mating pulley, and a linkage. The output end of the first motor is equipped with the drive pulley, the belt is wound around the drive pulley and the mating pulley, the linkage is connected to a portion of the belt, and the back side of the ejector hopper is connected to the linkage.

[0008] In some implementations, the linkage includes a connecting frame and a slider, with the connecting frame locked onto the slider and connected to the kicking hopper.

[0009] In some implementations, a guide rail is provided on the back side of the slider, and the slider slides along the direction of the guide rail.

[0010] In some implementations, the L-shaped hinge is opened or closed via a control component.

[0011] In some embodiments, the control component includes a second motor, a drive gear, and a driven gear. The drive gear is mounted on the output end of the second motor, the driven gear is mounted on the side end of the connecting rod, and an L-shaped opening and closing plate is mounted on the upper limit of the connecting rod. The drive gear meshes with the driven gear, and the driven gear, connecting rod, and L-shaped opening and closing plate rotate synchronously.

[0012] In some implementations, the kicking hopper is equipped with several limiting components to restrict the displacement of the L-shaped opening and closing plate.

[0013] In some implementations, in the initial state of the L-shaped opening and closing plate, the kicking bin contains material, and the position of the kicking bin is changed along a first direction by the drive assembly. In the initial state of the L-shaped opening and closing plate, the kicking bin is a container as a whole, and the first direction can be horizontal to the left or horizontal to the right, depending on the position of the kicking bin and other structures inside the packaging machine.

[0014] In some implementations, when the L-shaped hinged plate is in the open state, the L-shaped hinged plate rotates, and an opening for material to pass through is formed on the main slope.

[0015] By adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. This utility model controls the horizontal displacement of the material ejection bin through a drive component and independently adjusts the opening and closing of the L-shaped opening and closing plate through a control component. The two power systems work together without interfering with each other, ensuring the accuracy and reliability of the material distribution action.

[0017] 2. When this utility model is linked with a packaging machine, it can automatically respond to the weighing results. When the material is qualified, the kicking bin maintains its initial position and the material enters the packaging process normally. When the material is unqualified, the kicking bin moves and opens the L-shaped opening and closing plate to guide the material to the collection container, reducing manual intervention and improving sorting efficiency.

[0018] 3. The modular design of this utility model facilitates disassembly and maintenance, and the belt drive and gear set structure have high stability, making it suitable for continuous operation. Attached Figure Description

The drive gear 42 meshes with the driven gear 43, and the driven gear 43, the connecting rod 121, and the L-shaped opening and closing plate 12 rotate synchronously.

[0032] According to some embodiments of this utility model, optionally, a plurality of limiting members are provided on the kicking bin 1 to limit the displacement of the L-shaped opening and closing plate 12.

[0033] According to some embodiments of the present invention, optionally, in the initial state of the L-shaped opening and closing plate 12, the kicking bin 1 is filled with materials and the position of the kicking bin 1 is changed along the first direction by the driving component 2.

[0034] According to some embodiments of the present invention, optionally, when the L-shaped opening and closing plate 12 is in the open state, the L-shaped opening and closing plate 12 rotates, and an open opening for material to pass through is formed on the main slope surface 11.

[0035] Example 1

[0036] This embodiment provides a packaging kicking switching mechanism 100, including a kicking bin 1 and a driving component 2. The kicking bin 1 is driven to move by the driving component 2. The kicking bin 1 includes a main slope 11 that slopes downward to the right and an L-shaped opening and closing plate 12. In the initial state, the main slope 11 and the L-shaped opening and closing plate 12 cooperate to form a complete slope. In the open state, the L-shaped opening and closing plate 12 rotates around the connecting rod 121 as the rotation base point. The L-shaped opening and closing plate 12 intercepts and changes the tea conveying path.

[0037] The drive assembly 2 includes a first motor 21, a drive pulley 22, a belt 23, a mating pulley 24, and a linkage. The drive pulley 22 is installed at the output end of the motor. The belt 23 is wound around the drive pulley 22 and the mating pulley 24. The linkage is connected to a part of the belt 23. The back side of the kicking bin 1 is connected to the linkage.

[0038] The linkage includes a connecting frame 25 and a slider 26. The connecting frame 25 is locked onto the slider 26 and is connected to the kicking bin 1. A guide rail 27 is provided on the back side of the slider 26, and the slider 26 slides along the direction of the guide rail 27. The L-shaped opening and closing plate 12 is opened or closed by a control component 4. The control component 4 includes a second motor 41, a drive gear 42, and a driven gear 43. The drive gear 42 is installed at the output end of the second motor 41, and the driven gear 43 is installed on the side end of the connecting rod 121. The L-shaped opening and closing plate 12 is installed at the upper limit of the connecting rod 121. The drive gear 42 meshes with the driven gear 43, and the driven gear 43, the connecting rod 121, and the L-shaped opening and closing plate 12 rotate synchronously. Several limiting components are provided on the kicking bin 1 to limit the displacement of the L-shaped opening and closing plate 12. In the initial state of the L-shaped opening and closing plate 12, the kicking bin 1 is filled with materials and the position of the kicking bin 1 is changed along the first direction by the drive component 2; in the open state of the L-shaped opening and closing plate 12, the L-shaped opening and closing plate 12 rotates, and an open opening for materials to pass through is formed on the main slope 11.

[0039] The material kicking switching mechanism 100 of this packaging achieves the position switching of the kicking bin 1 and the opening and closing of the L-shaped opening and closing plate 12 through the coordinated action of the drive component 2 and the control component 4, thereby changing the material conveying path and completing the directional material distribution or interception function.

[0040] The operating principle of the packaging material kicking switching mechanism 100 is as follows: The L-shaped opening and closing plate 12 is tightly fitted with the main slope 11 of the kicking bin 1 to form a complete inclined slope. The material (such as tea leaves) can slide naturally down the slope to the predetermined outlet. The first motor 21 drives the linkage to move through the drive pulley 22, belt 23 and matching pulley 24, thereby pushing the kicking bin 1 to slide horizontally along the guide rail 27. The second motor 41 starts, and the drive gear 42 drives the driven gear 43 to rotate. The connecting rod 121 and the L-shaped opening and closing plate 12 rotate synchronously, so that the opening and closing plate flips around the connecting rod 121 and separates from the main slope 11. After the L-shaped opening and closing plate 12 rotates, its vertical part cuts into the material flow, blocking the material on the original slope from continuing to slide down. The main slope 11 forms an open opening due to the flipping of the opening and closing plate. The material can fall into the secondary channel (such as the collection container 3 or another conveying path) through the open opening. The limiting component on the kicking bin 1 limits the rotation angle of the L-shaped opening and closing plate 12 to prevent excessive displacement from causing structural interference.

[0041] Example 2

[0042] This embodiment provides a packaging machine, which includes the packaging material switching mechanism 100 of Embodiment 1.

[0043] In this embodiment, a collection container 3 is also provided, which is located below the L-shaped opening and closing plate 12.

[0044] Taking a tea packaging machine as an example, the packaging kick-off switching mechanism 100 is mainly used for: when the weight of the tea weighed by the weighing hopper on the packaging machine does not meet the requirements (both insufficient and excessive weight are considered non-compliant), the kick-off bin 1 is activated to intercept it; if the weight of the tea meets the requirements, the kick-off bin 1 remains in its initial side position and is not activated, allowing the remaining structures on the packaging machine to cooperate in completing the normal packaging work. The collection container 3 is used to collect the intercepted tea, which can then be removed from the collection container 3 and placed back into the material cylinder on the packaging machine.

[0045] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
