After the packaging of the packaging bag 7 is completed, it is detached from the fixation when it is above the conveying mechanism 4, falls above the conveying mechanism 4, and is conveyed to the next step by the conveying mechanism 4. Embodiment 2

[0042] Based on the first embodiment, Figure 1 - Figure 2 and Figure 5 As shown, an air outlet cavity 11 and a negative pressure cavity 13 are provided inside the packaging device body 2 , and the adaptive traction mechanism 5 is a breathable structure, and the air outlet cavity 11 and the negative pressure cavity 13 are separated by a partition 26 .

[0043] Furthermore, the air outlet cavity 11 and the negative pressure cavity 13 form a ring shape, and the air outlet cavity 11 is adapted to the position of the conveying mechanism 4 .

[0044] When in use, the packaging bag 7 adopts an airtight and lightweight structure such as a plastic packaging bag. The negative pressure of the negative pressure chamber 13 passes through the adaptive traction mechanism 5 to adsorb the packaging bag 7 to the surface of the adaptive traction mechanism 5, and through the intermittent rotation of the adaptive traction mechanism 5, the intermittent transportation of the packaging bag 7 is achieved.

[0045] like Figure 1 - Figure 4 As shown, the adaptive traction mechanism 5 includes an adsorption layer 18, a vertical rod 19 and a driving ring 20. A transmission base plate 9 is provided at the bottom of the packaging device body 2. The driving ring 20 is rotatably arranged inside the transmission base plate 9. A plurality of vertical rods 19 are provided. The plurality of vertical rods 19 are evenly distributed on the upper end surface of the driving ring 20. The adsorption layer 18 is distributed between the vertical rods 19 and the driving ring 20.

[0046] Furthermore, the adsorption layer 18 and the vertical rod 19 form an annular structure, and the adsorption layer 18 and the vertical rod 19 are both in contact with the outer end surfaces of the negative pressure chamber 13 and the air outlet chamber 11.

[0047] When in use, the driving ring 20 rotates intermittently to drive the rotation of the adsorption layer 18 and the vertical rod 19. The adsorption layer 18 is made of breathable material. The negative pressure of the negative pressure chamber 13 makes the packaging bag 7 adhere to the surface of the adsorption layer 18 and move with the rotation of the adsorption layer 18. The arrangement of the vertical rod 19 improves the structural strength of the adsorption layer 18, thereby improving the conveying effect of the packaging bag 7.

[0048] like Figure 1 - Figure 4 As shown, a reinforcing rib 23 is provided through the interior of the adsorption layer 18 , and adsorption holes 21 are provided in both the reinforcing rib 23 and the adsorption layer 18 .

The vertical rod 19 is provided with a cutting groove 25 compatible with the cutting mechanism 8.

[0050] When in use, the structural strength of the adsorption layer 18 is strengthened by the reinforcing ribs 23 , so that the adsorption layer 18 is arc-shaped and spliced ​​together into a ring-shaped arrangement, thereby improving the smoothness of conveying the packaging bag 7 .

[0051] like Figure 1 - Figure 2 As shown, a vane cavity 17 is provided inside the packaging device body 2, and a rotating shaft 12 is eccentrically arranged inside the vane cavity 17. The rotating shaft 12 is driven to rotate by the driving source 3. A fitting vane 14 is fixedly connected to the outer end face of the rotating shaft 12. The end of the fitting vane 14 facing away from the rotating shaft 12 is elastically fitted to the inner wall of the vane cavity 17. The vane cavity 17 is connected to the air outlet cavity 11 and the negative pressure cavity 13 respectively through the first connecting port 10 and the second connecting port 16.

[0052] When in use, the rotation of the rotating shaft 12 is driven by the packaging device main body 2. The packaging device main body 2 can be directly driven by a motor, etc. The rotating shaft 12 drives the fitting vane 14 to rotate while rotating, and the fitting vane 14 fits with the inner wall of the vane cavity 17, and the rotating shaft 12 is eccentrically arranged inside the vane cavity 17, so that negative pressure is provided to the inside of the negative pressure cavity 13 through the rotating shaft 12, and the gas is discharged through the air outlet cavity 11 after compression, and can also be used for returning the packaging bag 7, so that the packaging bag 7 falls into the interior of the conveying mechanism 4.

[0053] like Figure 1 - Figure 5 , Figure 7 and Fig. 9 As shown, a driving cavity 32 is opened inside the transmission base plate 9, and the rotating shaft 12 extends into the driving cavity 32. The rotating shaft 12 is eccentrically arranged inside the driving cavity 32. The outer end surface of the rotating shaft 12 is fixedly connected to a lever 33. The inner wall of the driving ring 20 is provided with multiple groups of driving rods 22, and the lever 33 is intermittently adapted with the driving rod 22.

[0054] Furthermore, the sum of the lengths of the drive cavity 32 and the drive rod 22 is greater than the minimum value from the outer edge of the rotating shaft 12 to the inner wall of the drive cavity 32 , and the sum of the lengths of the drive cavity 32 and the drive rod 22 is greater than the maximum value from the outer edge of the rotating shaft 12 to the inner wall of the drive cavity 32 .

[0055] When in use, the lever 33 is driven to rotate by the rotating shaft 12, and the lever 33 rotates eccentrically inside the driving chamber 32, so that the lever 33 and the driving rod 22 are intermittently adapted, and then the driving rod 22 drives the driving ring 20 to rotate intermittently. Embodiment 3

[0056] Based on the first and second embodiments, Figure 1 - Figure 3 , Figure 6 , Figure 8 and Fig.10As shown, a support ring 15 for auxiliary support of the adsorption layer 18 is further provided inside the negative pressure chamber 13 , and an opening mechanism 27 for opening the bag mouth of the packaging bag 7 is partially provided on the support ring 15 .

[0057] Furthermore, the opening mechanism 27 is adapted to the position of the feeding mechanism 1 , so that the feeding mechanism 1 can easily load the dried fruits into the packaging bag 7 .

[0058] When in use, a support ring 15 is provided inside the negative pressure chamber 13, and the support ring 15 fits against the inner wall of the adsorption layer 18, so as to support the adsorption layer 18 and prevent the adsorption layer 18 from being deformed under the negative pressure of the negative pressure chamber 13, thereby improving the conveying effect of the adsorption layer 18, and an opening mechanism 27 is provided for opening the packaging bag 7, without the need for an independent opening mechanism, thereby greatly reducing the cost of the device.

[0059] like Figure 1 - Figure 3 , Figure 6 , Figure 8 and Fig.10 As shown, the opening mechanism 27 includes a vertical sealing plate 29, an extension rod 30 and a receiving rod 31. The vertical sealing plates 29 are provided with two groups. The two groups of vertical sealing plates 29 are fixedly embedded in the negative pressure chamber 13. The two groups of vertical sealing plates 29 are respectively arranged to fit with the side of the vertical rod 19 facing the packaging device body 2. The extension rod 30 is fixedly connected to the end of the vertical sealing plate 29 away from the support ring 15, and the receiving rod 31 is fixedly arranged between the extension rods 30.

[0060] Furthermore, the height of the vertical sealing plate 29 is adapted to the vertical rod 19 , the extension rod 30 and the receiving rod 31 are arranged in a trapezoidal shape, and the extension rod 30 and the receiving rod 31 are concave toward one side of the packaging device body 2 , and the positions of the extension rod 30 and the receiving rod 31 are flush with the position of the reinforcing rib 23 .

[0061] During use, when the packaging bag 7 moves to the opening mechanism 27 along with the adsorption layer 18, under the negative pressure state inside the negative pressure chamber 13, the adsorption layer 18 is concave in the direction of the extension rod 30 and the receiving rod 31, and the adsorption hole 21 is provided on the surface of the adsorption layer 18. The adsorption layer 18 is adsorbed on the packaging bag 7, thereby driving the packaging bag 7 to open, and when the reinforcing rib 23 is concave in the direction of the receiving rod 31, the end of the adsorption layer 18 will move toward the middle, thereby causing the two ends of the packaging bag 7 to generate an extrusion force toward the middle, further improving its opening effect. At the same time, the vertical sealing plate 29 is fitted with the vertical rod 19 so that the end of the adsorption layer 18 moves along the surface of the vertical rod 19, which restricts the movement of the end of the adsorption layer 18 while avoiding the gap caused by the movement of the end of the adsorption layer 18 to affect the negative pressure effect inside the negative pressure chamber 13. At the same time, the concave design of the opening mechanism 27 also provides space for opening the packaging bag 7.

[0062] like Figure 1 - Fig.11As shown, the feeding mechanism 1 includes a feeding port 34, a filter plate 35, a filter cloth 36 and a pressure roller 37. The feeding port 34 is opened inside the feeding mechanism 1, the filter plate 35 is tilted and embedded inside the feeding port 34, the pressure roller 37 is rotatably embedded on the side where the feeding mechanism 1 and the packaging device body 2 are in contact, the filter cloth 36 is arranged below the filter plate 35, and a connecting hole 28 connected to the negative pressure chamber 13 is embedded inside the feeding mechanism 1, and the end of the connecting hole 28 facing away from the negative pressure chamber 13 is connected to the bottom of the filter cloth 36.

[0063] Furthermore, the end of the feeding port 34 is located at the side edge of the packaging device body 2, that is, above the packaging bag 7. There are multiple groups of pressing rollers 37, which are distributed in an arc shape on the inner surface of the feeding mechanism 1, and the pressing rollers 37 are in contact with the surface of the packaging bag 7.

[0064] During use, the dried fruits are fed into the feeding mechanism 1 through the feeding port 34. During the feeding process, the filter plate 35 can filter the debris or broken fruit shells in the dried fruits while guiding them, and the debris or broken fruit shells fall into the surface of the filter cloth 36 for collection. The inner surface of the feeding mechanism 1 is provided with a pressure roller 37 to fit the packaging bag 7, thereby improving the position stability of the packaging bag 7 during the bagging process. At the same time, in order to improve the debris processing effect, the bottom of the filter cloth 36 is also connected to the negative pressure chamber 13 through the connecting hole 28, and the negative pressure of the negative pressure chamber 13 further improves the collection effect of the debris.

[0065] Working principle: the packaging bag 7 is fixed to the side end surface of the packaging device body 2 by the adaptive traction mechanism 5, and the packaging bag 7 rotates intermittently with the adaptive traction mechanism 5, and the packaging bag 7 moves gradually along the outer end surface of the packaging device body 2. When the packaging bag 7 passes through the cutting mechanism 8, the packaging bag 7 is cut by the cutting mechanism 8. After the cutting, the packaging bag 7 enters the inside of the feeding mechanism 1 with the adaptive traction mechanism 5, and the dried fruits are loaded into the packaging bag 7 through the feeding mechanism 1. After the packaging bag 7 is packed, it is detached from the fixation when it is above the conveying mechanism 4, falls above the conveying mechanism 4, and is conveyed to the next step with the conveying mechanism 4. The packaging bag 7 adopts an airtight and lightweight structure such as a plastic packaging bag, and the negative pressure of the negative pressure chamber 13 is permeable. The packaging bag 7 is adsorbed to the surface of the adaptive traction mechanism 5 through the adaptive traction mechanism 5, and the intermittent transportation of the packaging bag 7 is realized through the intermittent rotation of the adaptive traction mechanism 5. The driving ring 20 intermittently rotates to drive the rotation of the adsorption layer 18 and the vertical rod 19. The adsorption layer 18 is made of a breathable material. The negative pressure of the negative pressure chamber 13 makes the packaging bag 7 adhere to the surface of the adsorption layer 18 and move with the rotation of the adsorption layer 18. The structural strength of the adsorption layer 18 is improved by the setting of the vertical rod 19, thereby improving the transportation effect of the packaging bag 7. The structural strength of the adsorption layer 18 is strengthened by the reinforcing ribs 23, so that the adsorption layer 18 is arc-shaped and spliced ​​into a ring-shaped setting, thereby improving the smoothness of the transportation of the packaging bag 7. The rotating shaft 1 is driven by the packaging device body 2 2, the packaging device body 2 can be directly driven by a motor or the like, the rotating shaft 12 drives the fitting rotary blade 14 to rotate while rotating, and the fitting rotary blade 14 fits with the inner wall of the rotary blade cavity 17, and the rotating shaft 12 is eccentrically arranged inside the rotary blade cavity 17, so that the negative pressure is provided to the inside of the negative pressure cavity 13 through the rotating shaft 12, and the gas is discharged through the gas outlet cavity 11 after compression, and can also be used for returning the packaging bag 7, so that the packaging bag 7 falls into the interior of the conveying mechanism 4, the rotation of the lever 33 is driven by the rotating shaft 12, and the lever 33 rotates eccentrically inside the driving cavity 32, so that the lever 33 is intermittently adapted to the driving rod 22, and then the driving rod 22 drives the driving ring 20 to rotate intermittently, by providing a support ring 15 inside the negative pressure cavity 13, the support ring 15 and the suction The inner wall of the attachment layer 18 is fitted to support the adsorption layer 18, thereby preventing the adsorption layer 18 from deforming under the negative pressure of the negative pressure chamber 13, improving the conveying effect of the adsorption layer 18, and providing an opening mechanism 27 for opening the packaging bag 7, without the need for an independent opening mechanism, greatly reducing the device cost, when the packaging bag 7 moves to the opening mechanism 27 along with the adsorption layer 18, under the negative pressure state inside the negative pressure chamber 13, the adsorption layer 18 is concave in the direction of the extension rod 30 and the receiving rod 31, and the surface of the adsorption layer 18 is provided with adsorption holes 21, the adsorption layer 18 is adsorbed on the packaging bag 7, thereby driving the packaging bag 7 to open, and when the reinforcing rib 23 is concave in the direction of the receiving rod 31, the end of the adsorption layer 18 will move toward the middle, so that the two ends of the packaging bag 7 generate an extrusion force toward the middle,To further improve its opening effect, the vertical sealing plate 29 is fitted with the vertical rod 19 so that the end of the adsorption layer 18 moves along the surface of the vertical rod 19. While limiting the movement of the end of the adsorption layer 18, it also avoids the gap caused by the movement of the end of the adsorption layer 18 affecting the negative pressure effect inside the negative pressure chamber 13. At the same time, the concave design of the opening mechanism 27 also provides space for the opening of the packaging bag 7. The dried fruit is fed into the feeding mechanism 1 through the feeding port 34. During the feeding process, the filter plate 35 can filter the debris or broken fruit shells in the dried fruit while guiding them, and they fall into the surface of the filter cloth 36 for collection.
