[0027] Combination Figures 1 to 3 As shown, the first aspect of this embodiment provides a follow-up unloading device, including: an unloading bracket 11, an unloading member 12 and a guide member 13, wherein the unloading member 12 and the guide member 13 are both arranged on the unloading bracket 11, wherein:

[0028] The material discharge member 12 includes a material discharge pipe 121, at least one of which is arranged in a horizontal direction (i.e., a first direction, Figure 2 The material receiving portion 1211 and the material discharging portion 1212 are connected to each other along the vertical direction (i.e., the second direction, Figure 2The material receiving portion 1211 is funnel-shaped, and the diameter of the material receiving portion 1211 is larger than the diameter of the material discharging portion 1212. The material discharging portion 1212 can extend into the bag body after the bottom and the side are heat-sealed; the guide member 13 is arranged at at least one end of the material discharging bracket 11 in the horizontal direction, and the guide member 13 includes a guide rod 131 and a positioning ring 132. The guide rod 131 and the material receiving portion 1211 are arranged on the same side of the material discharging bracket 11 in the vertical direction, and the positioning ring 132 is sleeved on the end of the guide rod 131 away from the material discharging bracket 11, and the positioning ring 132 can move relative to the guide rod 131 and can be locked with the guide rod 131. Specifically, with the unloading bracket 11 as the dividing line, the guide rod 131 and the material receiving portion 1211 are arranged on the upper side of the unloading bracket 11 in the vertical direction, and the material receiving portion 1211 is arranged on the lower side of the unloading bracket 11 in the vertical direction; the positioning ring 132 can be moved to a suitable position along the guide rod 132, and a threaded hole can be arranged on the positioning ring 132. By setting a thread matching the threaded hole on the guide rod 131, the positioning ring 132 and the guide rod 131 can be locked, so that the height of the positioning ring 132 on the guide rod 132 can be adjusted.

[0029] The follow-up unloading device provided in this embodiment may only have one unloading pipe 121 disposed on the unloading bracket 11, or may have multiple unloading pipes 121 disposed on the unloading bracket 11. If multiple unloading pipes 121 are disposed, the multiple unloading pipes 121 are arranged in a horizontal direction, and any adjacent unloading pipes 121 are spaced apart by a preset spacing. Those skilled in the art may set the number of unloading pipes 121 according to actual conditions. If it is a single-row packaging machine, one unloading pipe 121 is disposed on the unloading bracket 11; if it is a multi-row packaging machine, multiple unloading pipes 121 are disposed on the unloading bracket 11, for example Figure 1 Six feeding tubes 121 are arranged on the feeding bracket 11. Of course, those skilled in the art can also adjust the number of feeding tubes 121 in the multi-row packaging machine according to actual conditions.

[0030] It should be noted that the preset spacing is not further limited in this embodiment, and those skilled in the art may set it according to actual conditions.

[0031] On the basis of the above embodiment, as an optional implementation, the follow-up unloading device includes two guide members 13, which are respectively arranged at two ends of the unloading bracket 11 in the horizontal direction, and the two guide members 13 are respectively fixedly connected to the two ends of the unloading bracket 11 in the horizontal direction, and at least one unloading pipe 121 is arranged between the two guide members 13. Therefore, by respectively arranging the guide members 13 at the two ends of the unloading bracket 11 in the horizontal direction, when the unloading bracket 11 moves in the vertical direction, the unloading bracket 11 can drive the unloading pipe 121 to move more smoothly in the vertical direction, thereby avoiding the unloading bracket 11 and the unloading pipe 121 from tilting or deflecting in the process of moving in the vertical direction.

[0032] On the basis of the above embodiment, as an optional implementation, the material discharge tube 121 and the material discharge bracket 11 are detachably connected. Specifically, the material discharge member 12 also includes a positioning buckle 122 and a positioning card plate 123, both of which are arranged on the material discharge bracket 11, and a through hole is opened in the middle of the positioning card plate 123, and the positioning card plate 123 is sleeved on the outside of the material receiving portion 1211 through the through hole, and the positioning buckle 122 can be buckled on the positioning card plate 123, that is, the outside of the material receiving portion 1211 is in contact with the inner wall of the positioning card plate 123, and the positioning buckle 122 is buckled in the area between the inner wall and the outer wall of the positioning card plate 123. Thus, when the positioning buckle 122 is buckled on the positioning clamping plate 123, the feed tube 121 can be locked on the feed bracket 11, and when the positioning buckle 122 is not buckled on the positioning clamping plate 123, the feed tube 121 can be removed from the feed bracket 11 to facilitate cleaning of the feed tube 121. As an optional embodiment, the cross-section of the positioning clamping plate 123 is annular.

[0033] On the basis of the above embodiment, as an optional implementation, the blanking part 12 also includes a guide stud 124 and an elastic part 125. The guide stud 124 is arranged on the side wall of the blanking bracket 11. The positioning buckle 122 is fixed to the blanking bracket 11 through the guide stud 124. The elastic part 125 is sleeved on the guide stud 124, and one end of the elastic part 125 abuts against the positioning buckle 122, and the other end of the elastic part 125 abuts against the guide stud 124. The elastic part 125 is used to push the positioning buckle 122 toward the positioning clamping plate 123. Specifically, the positioning buckle 122 includes a first positioning buckle and a second positioning buckle that are integrally connected. The first positioning buckle and the second positioning buckle are vertically arranged so that the positioning buckle 122 is L-shaped, and the second positioning buckle is arranged parallel to the side wall of the blanking bracket 11. The guide stud 124 passes through the second positioning buckle and fixes the second positioning buckle on the blanking bracket 11. One end of the elastic member 125 abuts on the second positioning buckle, and the other end of the elastic member 125 abuts on the guide stud 124. The elastic member 125 pushes the first positioning buckle toward the positioning clamping plate 123 through the second positioning buckle, so that the positioning buckle 122 can be fixed on the positioning clamping plate 123, so as to fix the blanking tube 121 on the blanking bracket 11 more stably and avoid the blanking tube 121 from loosening. When the blanking tube 121 needs to be removed from the blanking bracket 11, the elastic member 125 also facilitates the loosening of the positioning buckle 122 fixed on the positioning clamping plate 123. As an optional implementation, the elastic member 125 may be a compression spring.

[0034] Combination Figures 4 to 6 As shown, the second aspect of this embodiment provides a packaging machine, which includes the follow-up feeding device 10 shown in the first aspect, and the packaging machine also includes a transverse sealing bag pulling device 20 and a former 30. The transverse sealing bag pulling device 20 is used to heat-seal the bag body transversely, and the transverse sealing bag pulling device 20 can also pull the bag body to move a certain distance in the vertical direction while heat-sealing the bag body transversely, which can be the distance of a packaging bag, so that the transverse sealing bag pulling device 20 also plays the role of pulling the bag; the former 30 is used to process the packaging material into a bag body. The transverse sealing bag pulling device 20 and the former 30 are both connected to the follow-up feeding device 10, and the transverse sealing bag pulling device 20 can drive the follow-up feeding device 10 to move in the vertical direction, and the former 30 is used to limit the displacement of the follow-up feeding device 10 in the vertical direction.

[0035] The height of the discharge port of the existing feeding device is fixed, so that the feeding pipe 121 is fixed in the vertical height. During the bag pulling process of the horizontal sealing bag pulling device 20, the packaging bag will be pulled downward in the vertical direction, and the height of the feeding pipe 121 and the bottom of the bag body will gradually increase, so that when the material falls from the feeding pipe 121 into the bag body, it is easy to cause dust. In this embodiment, the follow-up feeding device 10 is connected to the transverse sealing bag pulling device 20 and the former 30 respectively. After the transverse sealing bag pulling device 20 performs transverse heat sealing on the bottom of the bag body, the feeding tube 121 extends into the bag body, and the feeding tube 121 is close to the bottom of the bag body. Subsequently, during the process of the transverse sealing bag pulling device 20 pulling the bag, the transverse sealing bag pulling device 20 can drive the follow-up feeding device 10 to move in the vertical direction, so that the feeding tube 121 moves in the vertical direction with the transverse sealing bag pulling device 20, so that the height between the feeding tube 121 and the transverse sealing bag pulling device 20 remains unchanged, thereby keeping the height difference between the discharge port of the feeding tube 121 and the bottom of the bag body unchanged. The height difference between the discharge port of the material pipe 121 and the bottom of the bag body is a first preset value, thereby reducing the height between the discharge pipe 121 and the bottom of the bag body, which can not only ensure that the material falls into the bag body smoothly, but also reduce the dust generated during the falling process of the material, which is beneficial to improving the sealing of the packaged product; subsequently, when the horizontal sealing bag pulling device 20 drives the follow-up discharge device 10 to move in the vertical direction to the second preset value, the former 30 abuts against the follow-up discharge device 10 to stop the follow-up discharge device 10 from moving in the vertical direction, and the horizontal sealing bag pulling device 20 continues to move in the vertical direction until the material discharge is completed, and the horizontal sealing bag pulling device 20 performs horizontal heat sealing on the top of the bag body.

[0036] In this embodiment, the first preset value refers to the height difference between the discharge port of the discharge pipe 121 and the bottom of the bag body. The first preset value can be a fixed value. In this embodiment, the specific value of the first preset value is not further limited. Those skilled in the art can set it according to actual conditions, as long as it can reduce dust during the falling process of the material. As an optional implementation, the first preset value is one-third of the height of the bag body, thereby effectively reducing dust during the falling process of the material.

[0037] In this embodiment, the second preset value refers to the height value that the horizontal sealing bag pulling device 20 drives the follow-up feeding device 10 to move in the vertical direction. In this embodiment, the specific value of the second preset value is not further limited. Those skilled in the art can set it according to the difference between the height of the material to be loaded in the bag body and the height of the top of the bag body, as long as it can reduce the dust in the process of material falling and ensure that the former 30 is in contact with the follow-up feeding device 10. As an optional embodiment, the second preset value is 80% to 90% of the bag height, thereby better reducing the dust in the process of material falling and facilitating the packaging of the material.

[0038] Based on the above embodiment, as an optional implementation mode, Figure 6 As shown, the transverse bag sealing device 20 includes a first connecting rod 21 and a second connecting rod 22. The first connecting rod 21 is extended in the horizontal direction, and the second connecting rod 22 is arranged on the first connecting rod 21. The second connecting rod 22 is extended in the vertical direction. A fork 23 is fixedly arranged at one end of the second connecting rod 22 away from the first connecting rod 21. The transverse bag sealing device 20 also includes a driving member, which can drive the first connecting rod 21 to move in the vertical direction, so as to drive the second connecting rod 22 and the fork 23 arranged thereon to move in the vertical direction. A U-shaped groove is provided on the shift fork 23, and the guide rod 131 of the follow-up feeding device 10 can be snapped into the U-shaped groove, so that the shift fork 23 is connected to the guide rod 131 of the follow-up feeding device 10 through the U-shaped groove. When the shift fork 23 abuts against the positioning ring 132 of the follow-up feeding device 10, when the shift fork 23 moves in the vertical direction, the shift fork 23 can drive the follow-up feeding device 10 to move in the vertical direction; specifically, when the shift fork 23 moves upward in the vertical direction, the shift fork 23 can drive the positioning ring 132 abutting therewith to move upward in the vertical direction, thereby driving the follow-up feeding device 10 as a whole to move upward in the vertical direction through the positioning ring 132; when the shift fork 23 moves downward in the vertical direction, the follow-up feeding device 10 can slide downward in the vertical direction under its own gravity, so that the positioning ring 132 always abuts against the shift fork 23, thereby causing the follow-up feeding device 10 to move downward in the vertical direction along with the shift fork 23. When the former 30 limits the follow-up unloading device 10, when the fork 23 moves in the vertical direction, the follow-up unloading device 10 does not move with the fork 23, and the fork 23 can move in the vertical direction relative to the guide rod 131. At this time, the fork 23 does not abut against the positioning ring 132 of the follow-up unloading device 10, and the fork 32 is located between the positioning ring 132 and the end of the guide rod 131 connected to the unloading bracket 11. Therefore, the horizontal sealing bag pulling device 20 and the follow-up unloading device 10 are movably connected through the fork 23 and the guide rod 131, and when the fork 23 and the positioning ring 132 abut, the horizontal sealing bag pulling device 20 can drive the follow-up unloading device 10 to move in the vertical direction, so that the height of the unloading pipe 121 and the bottom of the bag body remains unchanged, reducing dust during the falling process of the material.

[0039] On the basis of the above embodiment, as an optional implementation, the former 30 includes at least one forming tube 31 arranged in a horizontal direction, and each forming tube 31 is arranged in a one-to-one correspondence with the discharge tube 121, that is, the number of forming tubes 31 is consistent with the number of discharge tubes 121. If the packaging machine is a single-row packaging machine, the number of forming tubes 31 and the discharge tube 121 are both set to one; if the packaging machine is a multi-row packaging machine, the number of forming tubes 31 and the discharge tube 121 are both set to multiple. Each forming tube 31 is extended in the vertical direction, and the forming tube 31 is sleeved on the outside of the discharge tube 121, and the forming tube 31 can abut against the side of the discharge bracket 11 away from the material receiving portion 1211, so that when the horizontal sealing bag pulling device 20 drives the follow-up discharge device 10 to move in the vertical direction until the forming tube 31 abuts against the side of the discharge bracket 11 away from the material receiving portion 1211, the follow-up discharge device 10 stops moving in the vertical direction, and the horizontal sealing bag pulling device 20 can continue to move in the vertical direction until the material discharge is completed, thereby completing the packaging of the material.

[0040] On the basis of the above embodiment, as an optional implementation, the packaging machine further includes a discharge pipe 40, the number of which is the same as the number of the discharge pipes 121, the discharge pipe 40 is connected to the material receiving portion 1211, the material receiving portion 1211 and the discharge pipe 40 are coaxially arranged, the diameter of the material receiving portion 1211 is larger than the diameter of the discharge pipe 40, and the material receiving portion 1211 is sleeved on the outside of the discharge pipe 40. Therefore, by sleeve-arranging the material receiving portion 1211 on the outside of the discharge pipe 40, when the material receiving portion 1211 moves along the vertical direction with the horizontal sealing bag pulling device 20, it is possible to prevent the discharge pipe 40 from being separated from the material receiving portion 1211, which causes the material to be scattered outside the discharge pipe 121 during the discharge process, thereby wasting the material.

[0041] A third aspect of the present embodiment provides a packaging method, which uses the packaging machine shown in the second aspect to perform packaging, and includes the following steps:

[0042] After the horizontal sealing bag pulling device 20 heat-seals the bottom of the bag body horizontally, the material falls into the bag body through the feeding tube 121 of the follower feeding device 10, and the horizontal sealing bag pulling device 20 pulls the bag body to move in the vertical direction. At the same time, the horizontal sealing bag pulling device 20 drives the follower feeding device 10 to move, so that the height between the feeding tube 121 and the bottom of the bag body is maintained at a first preset value;

[0043] When the transverse bag sealing device 20 drives the follow-up feeding device 10 to move to the second preset value, the former 30 abuts against the follow-up feeding device 10, so that the follow-up feeding device 10 stops moving in the vertical direction, and the transverse bag sealing device 20 moves in the vertical direction relative to the follow-up feeding device 10 until the material is fed, and the transverse bag sealing device 20 performs transverse heat sealing on the top of the bag body to complete the packaging of the material.

[0044] Specifically, after the transverse sealing bag pulling device 20 heat-seals the bottom of the bag body, the feeding tube 121 extends into the bag body, and the feeding tube 121 is close to the bottom of the bag body, and the material falls from the feeding tube to the bottom of the bag body. At the same time, in the process of the transverse sealing bag pulling device 20 moving the bag in the vertical direction, the fork 23 abuts against the positioning ring 132 of the follower feeding device 10, and the driving member drives the first connecting rod 21 to drive the second connecting rod 22 and the fork 23 arranged thereon to move in the vertical direction. The fork 23 drives the follower feeding device 10 to move in the vertical direction through the positioning ring 132, so that the feeding tube 121 The height between the discharge port and the bottom of the bag body remains unchanged. At this time, the height difference between the discharge port of the discharge pipe 121 and the bottom of the bag body is a first preset value; then, when the horizontal sealing bag pulling device 20 drives the follow-up discharge device 10 to move to the second preset value, the follow-up discharge device 10 abuts against the side of the forming tube 31 and the discharge bracket 11 away from the material receiving portion 1211, so that the follow-up discharge device 10 stops moving in the vertical direction, and the horizontal sealing bag pulling device 20 can continue to move in the vertical direction until the material is discharged. The horizontal sealing bag pulling device 20 performs horizontal heat sealing on the top of the bag body to complete the packaging of the material. The horizontal sealing bag pulling device 20 is reset, and the follow-up discharge device 10 is reset along with the horizontal sealing bag pulling device 20. Therefore, by packaging the material through the above method, dust can be reduced during the falling process of the material, which is conducive to improving the sealing of the packaged product and improving the quality of the packaged product.

[0045] It should be noted that the explanations of the first preset value and the second preset value are as described above and will not be repeated here.

[0046] Although the disclosure is as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the utility model.
