[0002] With the rapid development of the food industry and the increasing demands of consumers for food safety and convenience, automated packaging equipment is playing an increasingly important role in the food processing industry. Traditional raisin packaging is mostly done by automated equipment. However, most automated raisin packaging equipment requires raisins to be poured into a screen in batches and times for sieving. This requires multiple manual operations, which is not only cumbersome, but also causes raisins to be squeezed on the screen if too many are poured in, resulting in product quality problems.

[0003] Therefore, existing technologies need further development. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a raisin packaging machine to solve the technical problem that in the process of use, raisins need to be poured into the screen in batches and times for screening, which requires multiple manual operations. Not only is the operation cumbersome, but pouring in too many raisins can also cause the raisins to be squeezed on the screen, resulting in product quality problems.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: A raisin packaging machine is provided, comprising: a screening component, which is movably arranged in a vertical direction and is used to screen the raisins according to their specifications; a feeding component, which is disposed on top of the screening component, and has a feeding chamber and a sealing part, wherein the output end of the feeding chamber is located above the screening component, and the sealing part is disposed at the output end of the feeding chamber, and is used to avoid and block the output end of the feeding chamber; the sealing part is connected to the screening component, and is used to block or avoid the feeding chamber according to the movement of the screening component.

[0006] Furthermore, the raisin packaging machine also includes a housing with a processing chamber inside. At least a portion of the feeding assembly is located within the processing chamber, and a screening assembly is movably disposed within the processing chamber along the height direction of the housing. The feeding assembly includes: a feeding hopper installed on the top of the housing, extending through the housing into the processing chamber, and having a feeding cavity connected to the processing chamber; a feeding cover rotatably disposed at the bottom of the feeding hopper, forming a sealing portion; and a feeding rod disposed on the screening assembly, extending along the height direction of the housing, located below the feeding cover, and connected to the feeding cover. The screening assembly can drive the feeding cover to rotate via the feeding rod. When the screening assembly moves upward, the feeding rod drives the feeding cover to rotate upward, gradually closing the feeding cavity; when the screening assembly moves downward, the feeding rod drives the feeding cover to rotate downward, gradually opening the feeding cavity.

[0007] Further, the screening assembly includes: a first screen, which is movably disposed within the processing chamber along the height direction of the housing, the first screen having a first receiving end and a first discharging end, the first screen gradually tilting downward from the first receiving end to the first discharging end, and a discharge hopper located above the first receiving end; a discharge rod mounted on the first screen; and a second screen, which is movably disposed within the processing chamber along the height direction of the housing, the second screen located below the first screen, the second screen having a second receiving end and a second discharging end, the second screen gradually tilting downward from the second receiving end to the second discharging end, the second screen and the first screen being spaced apart along the height direction of the housing, and the aperture of the second screen being smaller than that of the first screen.

[0008] Furthermore, the raisin packaging machine also includes: a drive assembly, which includes: a connecting plate located inside the processing cavity and connected to the first screen and the second screen respectively; and a drive rod movably mounted on the housing along the height direction of the housing and connected to the connecting plate, so as to drive the first screen and the second screen to move through the connecting plate.

[0009] Furthermore, the drive assembly also includes: a drive element, which is mounted on one side of the housing; and a cam, the output end of which is connected to a cam drive, and the cam is connected to a drive rod so that the drive rod can be moved by the rotation of the cam.

[0010] Furthermore, the raisin packaging machine also includes: a discharge assembly, which includes: a first discharge bin connected to a first discharge end, a first discharge port opened on the side of the housing near the first discharge end, at least a portion of the first discharge bin located within the first discharge port, the first discharge bin being movably arranged along the height direction of the housing, and a first guide port opened on the side of the first discharge bin facing the ground; and a second discharge bin connected to a second screen, a second discharge port opened on the side of the housing near the first discharge end, the second discharge port and the first discharge port being spaced apart along the height direction of the housing, at least a portion of the second discharge bin located within the second discharge port, the second discharge bin being movably arranged along the height direction of the housing, and a second guide port opened on the side of the second discharge bin facing the ground.

[0011] Furthermore, the discharge assembly also includes: a first guide tube, which is connected to a first guide port, and the other end of the first guide tube is located inside the first packaging bag; and a second guide tube, which is connected to a second guide port, and the other end of the second guide tube is located inside the second packaging bag.

[0013] Furthermore, the raisin packaging machine also includes a collection hopper, which is located below the second screen and has a collection chamber that is connected to the processing chamber for collecting raisins smaller than the aperture of the second screen.

[0014] Beneficial effects: 1. The screening component and the feeding component form a linkage control structure. By moving the screening component up and down, the sealing part is intermittently triggered to open or close the feeding chamber. This prevents excessive feeding. At the same time, you only need to put the raisins into the feeding component. By intermittent feeding, the amount of raisins entering the screening component is controlled. This solves the technical problem that requires multiple manual operations, which is cumbersome. Also, if too many raisins are poured in, they will be squeezed on the screen, causing product quality problems.

[0015] 2. The discharge rod and the discharge cover form a lever-type linkage mechanism, which directly converts the vertical displacement of the screening component into the rotational motion of the discharge cover without the need for an additional drive device. This structure mechanically couples the discharge control with the screening operation, ensuring that the discharge action and the screening status are synchronized in real time, while reducing the complexity of the equipment.

[0016] 3. The stop bars constitute the limiting mechanism of the guide tube, which restricts the swing range of the upper part of the guide tube and prevents it from shifting position due to material impact or equipment vibration. This structure maintains the necessary flexibility of the guide tube while maintaining the alignment accuracy of the outlet. Furthermore, the vibration generated when the two guide tubes hit the two stop bars respectively accelerates the entry of raisins into the packaging bag and effectively prevents raisins from accumulating inside the guide tube.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] According to an embodiment of this utility model, a raisin packaging machine is provided. Please refer to [link / reference]. Figures 1 to 3The system includes: a screening component 1, which is movably arranged in a vertical direction and is used to screen raisins according to their specifications; and a feeding component 2, which is arranged on top of the screening component 1 and has a feeding chamber and a sealing part. The output end of the feeding chamber is located above the screening component 1, and the sealing part is arranged at the output end of the feeding chamber to avoid and block the output end of the feeding chamber. The sealing part is connected to the screening component 1 and can block or avoid the feeding chamber according to the movement of the screening component 1.

[0021] By adopting the above technical solution, the screening component 1 and the feeding component 2 form a linkage control structure. By moving the screening component 1 up and down, the sealing part is intermittently triggered to open or close the feeding chamber, preventing excessive feeding. At the same time, only raisins need to be placed in the feeding component 2. By intermittent feeding, the amount of raisins entering the screening component 1 is controlled, which solves the technical problems of needing to perform multiple manual operations, which is cumbersome, and that pouring too many raisins can easily cause raisin compression on the screen, resulting in product quality problems.

[0022] Please refer to the figure. The raisin packaging machine also includes a housing 3, which has a processing chamber. At least a portion of the feeding assembly 2 is located within the processing chamber. The screening assembly 1 is movably disposed within the processing chamber along the height direction of the housing 3. The feeding assembly 2 includes: a feeding hopper 4, which is installed on the top of the housing 3 and extends through the housing 3 into the processing chamber. The feeding hopper 4 has a feeding cavity that communicates with the processing chamber and is used to store raisins; and a feeding cover 5, which is rotatably disposed at the bottom of the feeding hopper 4. A sealing section is formed to control the opening degree of the discharge chamber; a discharge rod 6 is set on the screening assembly 1, extending along the height direction of the housing 3, and located below the discharge cover 5. The discharge rod 6 is connected to the discharge cover 5, and the screening assembly 1 drives the discharge cover 5 to rotate through the discharge rod 6; wherein, when the screening assembly 1 moves upward, the discharge rod 6 drives the discharge cover 5 to rotate upward, gradually closing the discharge chamber; when the screening assembly 1 moves downward, the discharge rod 6 drives the discharge cover 5 to rotate downward, gradually opening the discharge chamber.

[0023] By adopting the above technical solution, the discharge rod 6 and the discharge cover 5 form a lever-type linkage mechanism, which directly converts the vertical displacement of the screening component 1 into the rotational motion of the discharge cover 5 without the need for an additional drive device. This structure mechanically couples the discharge control with the screening operation, ensuring that the discharge action and the screening status are synchronized in real time, while reducing the complexity of the equipment.

[0024] Please refer to Figure 1 and Figure 2The screening assembly 1 includes: a first screen 7, which is movably disposed in the processing chamber along the height direction of the housing 3. The first screen 7 has a first receiving end and a first discharging end. The first screen 7 gradually slopes downward from the first receiving end to the first discharging end. The discharge hopper 4 is located above the first receiving end. The discharge rod 6 is installed on the first screen 7. A second screen 8 is movably disposed in the processing chamber along the height direction of the housing 3. The second screen 8 is located below the first screen 7. The second screen 8 has a second receiving end and a second discharging end. The second screen 8 gradually slopes downward from the second receiving end to the second discharging end. The second screen 8 and the first screen 7 are spaced apart along the height direction of the housing 3. The aperture of the second screen 8 is smaller than that of the first screen 7.

[0025] By adopting the above technical solution, a stepped screening structure is formed by two-stage inclined screens. The first screen 7 performs primary screening of raisins, and large particles that do not pass through slide along the inclined surface to the first discharge end, while smaller particles that pass through the screen holes fall into the second screen 8 for secondary screening. This design achieves material grading through gravity flow, and the synchronous vibration of the two-stage screens can effectively prevent screen hole clogging and improve grading accuracy.

[0026] Please refer to Figure 3 The raisin packaging machine also includes: a drive assembly 9, which includes: a connecting plate 10 located inside the processing chamber and connected to the first screen 7 and the second screen 8 respectively; and a drive rod 11 movably mounted on the housing 3 along the height direction of the housing 3, connected to the connecting plate 10, and driving the first screen 7 and the second screen 8 to move through the connecting plate 10.

[0027] By adopting the above technical solution, the connecting plate 10 integrates the first screen 7 and the second screen 8 into a synchronous motion unit, and the linkage lifting and lowering of the two screens can be realized through a single drive rod 11. This integrated design simplifies the drive structure, ensures the consistency of the movement of the two-stage screens, and avoids the problem of material accumulation caused by asynchronous movement.

[0028] Please refer to Figure 2 The drive assembly 9 also includes: a drive member 12, which is mounted on one side of the housing 3; and a cam 13, the output end of the drive member 12 being drivenly connected to the cam 13, which is connected to the drive rod 11 so that the drive rod 11 can be moved by the rotation of the cam 13.

[0029] By adopting the above technical solution, the cam 13 mechanism converts the rotational motion of the drive component 12 into the reciprocating linear motion of the drive rod 11. By adjusting the profile of the cam 13, the vibration amplitude and frequency of the screen can be precisely controlled. This transmission method features controllable motion trajectory and low impact, which is beneficial for maintaining the stability of the screening operation.

[0030] Please refer to Figure 1 and Figure 3 The raisin packaging machine also includes: a discharge assembly 14, which includes: a first discharge bin 15 connected to a first discharge end, a first discharge port on the side of the housing 3 near the first discharge end, at least a portion of the first discharge bin 15 located within the first discharge port, the first discharge bin 15 being movably arranged along the height direction of the housing 3, and a first guide port on the side of the first discharge bin 15 facing the ground; and a second discharge bin 16 connected to a second screen 8, a second discharge port on the side of the housing 3 near the first discharge end, the second discharge port and the first discharge port being spaced apart along the height direction of the housing 3, at least a portion of the second discharge bin 16 located within the second discharge port, the second discharge bin 16 being movably arranged along the height direction of the housing 3, and a second guide port on the side of the second discharge bin 16 facing the ground.

[0031] By adopting the above technical solution, the movable discharge bin structure allows the first discharge bin 15 and the second discharge bin 16 to rise and fall synchronously with the screen, always maintaining connection with the screen's discharge end. This design prevents material spillage during transfer, and the dual guide port setting enables independent output of raisins of different sizes, facilitating subsequent sorting and packaging.

[0032] Please refer to Figure 3 The discharge assembly 14 further includes: a first guide tube 17, which is connected to a first guide port and the other end of the first guide tube 17 is located inside a first packaging bag; and a second guide tube 18, which is connected to a second guide port and the other end of the second guide tube 18 is located inside a second packaging bag.

[0033] Specifically, the first feed tube 17 and the second feed tube 18 are flexible feed tubes.

[0034] By adopting the above technical solution, the flexible feed tube can adapt to the lifting and lowering movement of the discharge hopper, ensuring the continuity of the material conveying channel. The dual-channel feed design enables simultaneous packaging of graded materials, significantly improving packaging efficiency, and the positioning of the feed tube end inside the packaging bag effectively suppresses dust diffusion.

[0035] Please refer to Figure 3The raisin packaging machine also includes: a first stop rod 19, which is installed on the outer wall of the housing 3 and is located on the side of the housing where the first guide port is provided, and protrudes from the housing 3; the first stop rod 19 is located above the first guide tube 17 and is used to stop the first guide tube 17; a second stop rod 20, which is installed on the outer wall of the housing 3 and is located on the side of the housing where the second guide port is provided, and protrudes from the housing 3; the second stop rod 20 is located above the second guide tube 18 and is used to stop the second guide tube 18.

[0036] By adopting the above technical solution, the stop bar constitutes the limiting mechanism of the guide tube, which prevents the guide tube from shifting position due to material impact or equipment vibration by restricting the swing range of the upper part of the guide tube. This structure maintains the necessary flexibility of the guide tube while maintaining the alignment accuracy of the outlet. Moreover, the vibration generated when the two guide tubes hit the two stop bars respectively can accelerate the entry of raisins into the packaging bag and effectively prevent raisins from accumulating in the guide tube.

[0037] Please refer to Figure 3 The raisin packaging machine also includes a collection hopper 21, which is located below the second screen 8. The collection hopper 21 has a collection chamber that is connected to the processing chamber for collecting raisins smaller than the aperture of the second screen 8.

[0038] By adopting the above technical solution, the collecting hopper 21, as a three-stage collection device, can receive fine particulate materials that have passed through the two-stage screening, forming a complete three-stage sorting system. Its funnel-shaped structure guides the material to fall in a concentrated manner, facilitating the unified collection of ultra-small raisins and realizing the graded utilization of materials of all particle sizes.

[0039] Working principle: When the raisin packaging machine starts, the drive component 12 drives the cam 13 to rotate, and the drive rod 11 reciprocates along the height direction of the housing 3 under the action of the cam 13. This, in turn, synchronously pulls the first screen 7 and the second screen 8 to vibrate up and down through the connecting plate 10. The raisins in the hopper 4 fall to the first receiving end of the first screen 7 under gravity. If the screening component 1 is in a low position at this time, the discharge rod 6 drives the discharge cover 5 to rotate downwards, fully opening the discharge chamber, and the raisins continue to fall. When the first screen 7 moves upwards, it drives the discharge rod 6 to rotate upwards in conjunction with the discharge cover 5 to close the discharge chamber and stop feeding. Each up-and-down movement of the first screen 7 forms one discharge, achieving intermittent discharge and preventing excessive raisins from being discharged at the first screen. Excessive accumulation on screen 7 causes raisins larger than its aperture to slide down the inclined surface into the first discharge bin 15 during the vibration of the first screen 7, and then into the first packaging bag via the first guide pipe 17. Smaller particles passing through the first screen 7 fall into the second screen 8. After secondary screening, medium-sized particles slide down the second screen 8 into the second discharge bin 16, and are guided into the second packaging bag via the second guide pipe 18. The smallest particles pass through the second screen 8 and fall into the collection hopper 21 for centralized collection. The first stop bar 19 and the second stop bar 20 limit the swing amplitude of the guide pipes 17 and 18 to ensure that the discharge port is always aligned with the packaging bag. During the process of the two guide pipes hitting the two stop bars respectively, vibration is generated, which accelerates the entry of raisins into the packaging bag and effectively prevents raisins from accumulating in the guide pipes.
