Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging devices, specifically a packaging device for nut processing. Background Technology
[0002] Nuts are weighed quantitatively by a quantitative weighing device (whose core is a pressure sensor) and then transported by a conveying mechanism to the packaging section and put into packaging bags.
[0003] Existing dispensing devices typically have a rotating valve plate. After the packaging bag is effectively fitted onto the feed inlet, the valve plate is opened to allow the nuts to fall into the packaging bag. However, it needs to be closed manually or electrically afterwards to prevent subsequent nuts from falling directly downwards. It is impossible to reset and close the valve plate immediately after the nuts fall. Utility Model Content
[0004] The purpose of this utility model is to provide a nut processing and packaging device in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a nut processing and packaging device, comprising a feeding hopper, the inner wall of which has a conical structure that is wider at the top and narrower at the bottom, a hollow sphere with a spherical structure connected to the bottom end of the narrow opening of the feeding hopper, and a straight cylindrical feeding cylinder connected to the output end of the hollow sphere, the inner cavity of the hollow sphere communicating with the inner cavities of the feeding hopper and the feeding cylinder, a rotary motor fixedly mounted on the outer wall of the feeding cylinder by a fixing frame, a 90-degree rotation mechanism mounted on the output end of the rotary motor, a rotating valve plate located in the inner cavity of the hollow sphere coaxially connected to the output end of the 90-degree rotation mechanism, and limit reset mechanisms mounted on both ends of the rotating valve plate.
[0006] As a further embodiment of this utility model: the 90-degree rotation mechanism includes a drive gear coaxially fixedly mounted on the end of the output shaft of the rotary motor. The tooth blocks on the outer wall of the drive gear are evenly distributed in the 90-degree direction. A driven gear is arranged directly above the drive gear. A rotating shaft is fixedly mounted on one end of the driven gear. The other end of the rotating shaft is fixedly connected to one end of the rotating valve plate.

The rotating plate and the first fixing plate are aligned with each other, and a torsion spring is fixedly installed between the rotating plate and the first fixing plate. The torsion spring is sleeved on the outer periphery of the rotating shaft.
[0008] As a further embodiment of this utility model: the limiting and resetting mechanism further includes a rotating shaft welded to the other end of the rotating valve plate and a second fixing plate integrally formed on the other end of the outer wall of the hollow ball. The center of the second fixing plate coincides with the rotation center of the rotating valve plate. The second fixing plate is provided with an arc-shaped groove that matches the rotation trajectory of the rotating valve plate. The arc-shaped groove is distributed at ninety degrees.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1-4In this embodiment of the present invention, a nut processing and packaging device includes a feeding hopper 1. The inner wall of the feeding hopper 1 has a conical structure that is wider at the top and narrower at the bottom. A hollow ball 2 with a spherical structure is connected to the bottom end of the narrow opening of the feeding hopper 1. The output end of the hollow ball 2 is connected to a straight cylindrical feeding cylinder 3. The inner cavity of the hollow ball 2 is connected to the inner cavities of the feeding hopper 1 and the feeding cylinder 3. A rotary motor 5 is fixedly installed on the outer wall of the feeding cylinder 3 through a fixing frame 4. A 90-degree rotation mechanism is installed at the output end of the rotary motor 5. A rotary valve plate 9 located in the inner cavity of the hollow ball 2 is coaxially connected to the output end of the 90-degree rotation mechanism. Limiting and resetting mechanisms are installed at both ends of the rotary valve plate 9.
[0019] In this embodiment: First, the weighed nuts fall into the hollow ball 2 through the top of the feeding hopper 1 and are blocked by the horizontal rotating valve plate 9. At this time, the packaging bag is placed on the bottom outer wall of the feeding cylinder 3. Then, the rotating motor 5 is controlled to run. The controller controls the output end of the rotating motor 5 to rotate one revolution (monitored by the shaft encoder). At this time, the 90-degree rotation mechanism installed on the output shaft of the rotating motor 5 synchronously drives the rotating valve plate 9 to rotate 90 degrees to the vertical state. At this time, the nuts located on the rotating valve plate 9 fall into the packaging bag. Then, the rotating valve plate 9 is reset to the horizontal state under the reset force of the limit reset mechanism, completing the packaging of nuts.
[0020] Please refer to this carefully. Figure 1 and Figure 2 The 90-degree rotation mechanism includes a drive gear 7 coaxially fixedly mounted on the end of the output shaft of the rotary motor 5. The tooth blocks on the outer wall of the drive gear 7 are evenly distributed in the 90-degree direction. A driven gear 8 is arranged directly above the drive gear 7. A rotating shaft 11 is fixedly mounted on one end of the driven gear 8. The other end of the rotating shaft 11 is fixedly connected to one end of the rotating valve plate 9. A protective shell 6, which is fixedly connected to the fixed frame 4, is rotatably mounted on the outer side of the driven gear 8 and the drive gear 7.
[0021] In this embodiment: During the operation of the rotary motor, the driving gear 7 rotates, and the driving gear 7 rotates from a state of disengagement with the driven gear 8 to a state of engagement. In the engagement state, the driven gear 8 rotates, and the driven gear 8 drives the rotating valve plate 9 to rotate synchronously until the driven gear 8 drives the rotating valve plate 9 to rotate 90 degrees. At this time, the rotating valve plate 9 rotates from a horizontal state to a vertical state, and all the nuts on the rotating valve plate 9 fall down. Then, the teeth of the continuously rotating driving gear 7 separate from the driven gear 8. At this time, the limit reset mechanism drives the rotating valve plate 9 to reset and return to the initial horizontal position.
[0022] Please refer to this carefully. Figure 3 and Figure 4The limiting and resetting mechanism includes a rotating plate 12 fixedly installed on the outer wall of the rotating shaft 11 and a first fixing plate 10 integrally formed on the outer wall of the hollow sphere 2. The rotating plate 12 and the first fixing plate 10 are aligned. A torsion spring 13 is fixedly installed between the rotating plate 12 and the first fixing plate 10. The torsion spring 13 is sleeved on the outer circumference of the rotating shaft 11. The limiting and resetting mechanism also includes a rotating shaft 11 welded to the other end of the rotating valve plate 9 and a second fixing plate 15 integrally formed on the other end of the outer wall of the hollow sphere 2. The center of the second fixing plate 15 coincides with the rotation center of the rotating valve plate 9. An arc-shaped groove 16 is opened on the second fixing plate 15, which matches the rotation trajectory of the rotating valve plate 9. The arc-shaped groove 16 is distributed at ninety degrees. A connecting frame 14 is installed at the center of the other end of the rotating valve plate 9. A sliding column is integrally formed at the end of the connecting frame 14 away from the rotating valve plate 9. The sliding column is movably connected to the inner side of the arc-shaped groove 16.
[0023] In this embodiment: During the rotation of the rotating valve plate 9, the rotating valve plate 9 drives the rotating plate 12 to rotate synchronously through the rotating shaft 11, while the first fixed plate 10 remains stationary. Therefore, the end of the torsion spring 13 connected to the rotating plate 12 rotates accordingly, and the torsion spring 13 twists. When the driven gear 8 and the driving gear 7 are misaligned, the torsion spring 13 can drive the rotating plate 12 to reset. The rotating plate 12 drives the rotating valve plate 9 to reset through the rotating shaft 11. At the same time, the other end of the rotating valve plate 9 drives the connecting frame 14 to rotate synchronously and reset. The connecting frame 14 drives the sliding column to move synchronously in the arc groove 16. When the rotating valve plate 9 is reset to the horizontal state, the sliding column contacts one end of the arc groove 16, thus keeping the rotating valve plate 9 in the current horizontal state.
[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
