Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, and more specifically to an anti-fragmentation side bagging device, an anti-fragmentation side bag feeding packaging machine and an anti-fragmentation side weighing packaging integrated machine. Background Art

[0002] For foods such as quick-frozen dumplings and rice crusts, their texture is relatively brittle and they have large flaky edges and corners. If they are directly packed into bags after weighing, the food may easily be hit and break into pieces.

[0003] For example, the utility model patent with the authorization announcement number CN209988188U and the authorization announcement date January 24, 2020, and the name of the patent is "Anti-crushing weighing and packaging all-in-one machine". In this anti-crushing weighing and packaging all-in-one machine, the material weighed by the combination scale first falls onto the material receiving conveyor, and the height difference between the bottom of the combination scale and the material receiving conveyor is small, so as to avoid collision and breakage between materials; the bag sealing device is tilted as a whole, and the material slides downward in the discharge pipe of the bag sealing device, so as to further avoid collision and breakage between materials, thereby improving the packaging quality.

[0004] The above-mentioned prior art can only solve the problem of preventing the falling materials from breaking after being weighed by the combination weigher. Although the bag sealing device is tilted as a whole, and the materials slide downward in the discharge pipe of the bag sealing device, when they fall to the bottom of the bag, the materials will still collide with each other, causing the edges of the materials to break. That is, the above-mentioned prior art has a poor effect of preventing the edges of the materials from breaking when they are bagged, and there is still a situation where the materials fall to the bottom of the bag and collide with each other and break. Utility Model Content

When the material in the drop hopper falls into the bag, the support platform slowly descends. After all the materials are loaded into the bag, the support platform is reset to wait for the next bag to be supported. The anti-fragmentation edge bagging device of the present application changes the distance between the bottom of the bag and the drop hopper by setting a support platform, reduces the drop difference between the material from the drop hopper to the bottom of the bag, thereby reducing the collision between the materials when they fall from the drop hopper to the bottom of the bag, reduces the edge breakage rate, and thus improves the packaging quality.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings of the utility model specification to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example 1

[0031] As a preferred embodiment of the present invention, refer to the attached specification Figure 1 and attached Figure 2 As shown, the present embodiment discloses an anti-fragmentation edge bagging device, comprising a feeding hopper 1 and a rotating table 2 for driving the packaging bag 5 to move to the bottom of the receiving hopper for receiving materials, and also comprising a support table 3 arranged below the feeding hopper 1 and the packaging bag 5 located below the feeding hopper 1, wherein the support table 3 is assembled on a lifting drive assembly 4; after the rotating table 2 drives the empty packaging bag 5 to move to the bottom of the feeding hopper 1, the lifting drive assembly 4 drives the support table 3 to rise, and the support table 3 holds the bottom of the packaging bag 5 and moves it toward the bottom of the feeding hopper 1 to shorten the height difference between the bottom of the packaging bag 5 and the feeding hopper 1, and after reaching the set height, the support table 3 remains stationary, and during the process of the material falling into the packaging bag 5 through the feeding hopper 1, the lifting drive assembly 4 drives the support table 3 to descend, and after all the materials fall into the packaging bag 5, the lifting drive assembly 4 drives the support table 3 to descend and reset. It should be noted that during the material dropping process, the speed at which the lifting drive assembly 4 drives the support platform 3 to descend can be set according to the amount of a bag of material, ensuring that the material can smoothly fall from the drop hopper 1 into the packaging bag 5 without causing the collision between the materials to be aggravated during the material dropping due to the large height difference between the bottom of the packaging bag 5 and the drop hopper 1.

[0032] In this embodiment, when bagging materials, the support platform 3 is used to change the height difference between the bottom of the packaging bag 5 and the drop hopper 1, so as to avoid the problem of broken edges caused by violent collision when the materials fall into the packaging bag 5 due to the large height difference, which effectively improves the problem of broken edges when the materials are dropped and improves the packaging quality.

[0033] As an implementation of this embodiment, the lifting drive assembly 4 is provided with a lifting guide rail 6, and the support platform 3 is slidably assembled on the lifting guide rail 6. The lifting guide rail 6 ensures the stability of the support platform 3 during the lifting movement.

[0034] As an example of this embodiment, the lifting drive assembly 4 includes a transmission component and a driving component, the driving component drives the transmission component to move, and the transmission component is connected to the support platform 3 to drive the support platform 3 to move up and down. The transmission component is a synchronous belt transmission component or a screw transmission component, and the driving component is a servo motor component.

[0035] As another example of this embodiment, the lifting drive component 4 is a linear motor.

[0036] As another implementation method of this embodiment, refer to the attached Figure 1 and attached Figure 2 As shown, the drop hopper 1 is assembled on the frame 8 through the telescopic drive assembly 7, and the telescopic drive assembly 7 drives the drop hopper 1 to be inserted into the bag mouth of the empty packaging bag 5 below it, and drives the drop hopper 1 to shake up and down when the material falls into the packaging bag 5 through the drop hopper 1. When the material falls into the packaging bag 5, the drop hopper 1 is telescopically shaken to avoid the situation that the material is accumulated in the drop hopper 1 and affects the material discharge. By shaking the drop hopper 1, the material falls from the drop hopper 1 into the packaging bag 5 faster.

[0037] Example 2

[0038] As another preferred embodiment of the present invention, refer to the attached specification. Figure 3 As shown, the present embodiment discloses an anti-fragmentation edge bag packaging machine, comprising a frame 8, a bag making machine, a bag loading device, a bag opening device 9, a sealing device 10 and the anti-fragmentation edge bagging device as described in the above embodiment, wherein the bag loading device, the hopper 1 and the sealing device 10 are arranged along the circumference of the rotating table 2, the bag making machine is docked with the bag loading device, and the bag loading device transfers the packaging bag 5 made by the bag making machine to the rotating table 2, the bag opening device 9 is used to open the bag mouth of the packaging bag 5 on the rotating table 2, and the packaging bag 5 that has completed the material receiving is driven by the rotating table 2 to the sealing device 10 for sealing.

[0039] Compared with the prior art, the anti-shatter edge bag packaging machine described in this embodiment is different from the existing bag packaging machine in that a liftable support platform 3 is arranged under the drop hopper 1. When the rotating table 2 drives the empty packaging bag 5 to move to the bottom of the drop hopper 1, the lifting drive component 4 drives the support platform 3 to rise, and the support platform 3 holds the bottom of the packaging bag 5 and moves toward the bottom of the drop hopper 1 to shorten the height difference between the bottom of the packaging bag 5 and the drop hopper 1. After reaching the set height, the support platform 3 remains stationary. During the process of the material falling into the packaging bag 5 through the drop hopper 1, the lifting drive component 4 drives the support platform 3 to descend slowly to ensure that the material can fall into the packaging bag 5 smoothly without affecting the material dropping due to the distance between the bottom of the packaging bag 5 and the drop hopper 1. After all the materials fall into the packaging bag 5, the lifting drive component 4 drives the support platform 3 to descend and reset.

[0040] It should be noted that during the material dropping process, the speed at which the lifting drive assembly 4 drives the support platform 3 to descend can be set according to the amount of a bag of material, ensuring that the material can smoothly fall from the drop hopper 1 into the packaging bag 5 without causing the collision between the materials to be aggravated during the material dropping due to the large height difference between the bottom of the packaging bag 5 and the drop hopper 1.

[0041] The anti-shatter edge feeding bag packaging machine of this embodiment adopts an anti-shatter edge bagging device, which also has the function and effect of preventing the material from breaking when filling the material into the packaging bag 5. Compared with the existing bag feeding packaging machine, it only needs to set the lifting drive assembly 4 and the support platform 3 under the drop hopper 1 to realize the anti-shatter edge bagging of the material. The improvement to the existing bag feeding packaging machine is relatively small, and it is easy to realize the transformation and upgrading of the existing bag feeding packaging machine.

[0042] Example 3

[0043] As another preferred embodiment of the present invention, refer to the attached specification. Figure 4 As shown, the present embodiment discloses an anti-fragmentation edge weighing and packaging integrated machine, comprising the anti-fragmentation edge bag feeding packaging machine described in the above-mentioned embodiment 2, a multi-head combination weigher 11, a buffer receiving hopper 12 and a collecting hopper 13, wherein the buffer receiving hopper 12 is located below the multi-head combination weigher, and the collecting hopper 13 is located below the buffer receiving hopper 12 and at the outlet of the buffer receiving hopper 12; the multi-head combination weigher 11, the buffer receiving hopper 12 and the collecting hopper 13 are assembled above the drop hopper 1 of the anti-fragmentation edge bag feeding packaging machine through a mounting frame 14; the axes of the multi-head combination weigher 11, the buffer receiving hopper 12, the collecting hopper 13 and the drop hopper 1 coincide.

[0044] In this embodiment, a buffer receiving hopper 12 and a collecting hopper 13 are arranged below the multi-head combination weigher 11. The setting of the buffer receiving hopper 12 reduces the drop of the material falling from the multi-head combination weigher 11, and reduces the probability of material edge fragmentation after weighing. The setting of the collecting hopper 13 reduces the drop between the material in the buffer receiving hopper 12 and the drop hopper 1. The material falls from the buffer receiving hopper 12 to the collecting hopper 13. When the material falls into the drop hopper 1, the drop of the material is reduced through multi-stage dropping, thereby reducing the edge fragmentation rate. The setting of the collecting hopper 13 is also conducive to collecting the material falling from the multi-head combination weigher 11, and then the material falls into the drop hopper 1 as a whole after collection. While reducing the drop of the material, it is also convenient for the collection of the material. The material falls into the drop hopper 1 as a whole, which does not affect the subsequent drop of the multi-head combination weigher 11, thereby improving the packaging efficiency.

[0045] As an implementation method of this embodiment, refer to the attached Figure 5 As shown, the collecting hopper 13 includes a support frame, a plurality of collecting plates 17 and a driving assembly, wherein the support frame includes an upper supporting ring 15 and a lower supporting ring 16; the upper ends of the plurality of collecting plates 17 are rotatably connected to the upper supporting ring 15, and the lower ends of the plurality of collecting plates 17 are assembled on the lower supporting ring 16 through the driving assembly; the plurality of collecting plates 17 are all arranged tilted; when the collecting hopper 13 is in a closed state, the plurality of collecting plates 17 are spliced ​​together to form the collecting hopper 13 with a closed bottom outlet; when the bottom outlet of the collecting hopper 13 is opened, the driving assembly drives the lower ends of the plurality of collecting plates 17 to rotate around their upper ends and the connecting piece 19 of the upper supporting ring 15 in a set first direction to a set angle, and the lower ends of adjacent collecting plates 17 partially overlap, thereby opening the bottom outlet of the collecting hopper 13; after the driving assembly drives the plurality of collecting plates 17 to reset, the bottom outlet of the collecting hopper 13 is closed.

[0046] The present embodiment uses a plurality of collecting plates 17 to be spliced ​​into a petal-shaped collecting hopper 13, which is conducive to the concentration of materials at the bottom of the collecting hopper 13. When releasing materials, the collecting plates 17 rotate in a set direction by a set angle to open the bottom opening of the collecting hopper 13, and the concentrated materials are released together. After the materials are released, the collecting plates 17 rotate in a set direction by a set angle in the opposite direction of the set direction, and the bottom opening of the collecting hopper 13 is closed, which is convenient for the next material collection. Compared with the existing material receiving conveyor, the collecting hopper 13 of the utility model can better concentrate the materials output from different hoppers of the combination weigher and release them together into the packaging machine. The inclined collecting plates 17 also reduce the drop of the materials. The opening method of the collecting hopper 13 also further shortens the drop of the materials, which can effectively avoid the occurrence of broken edges caused by the large drop of the materials.

[0047] As an example of this embodiment, the driving assembly includes a driving ring 18, a plurality of connecting members 19 and a driving member. The driving ring 18 is assembled concentrically with the lower support ring 16 and is assembled on the lower support ring 16 through a slider rail structure 22. The driving member is connected to the driving ring 18 to drive the driving ring 18 to rotate on the lower support ring 16; the connecting member 19 corresponds to the collecting plate 17, one end of the connecting member 19 is hinged to the driving ring 18, and the other end is hinged to the bottom of the collecting plate 17.

[0048] As another example of this embodiment, a connecting column I 20 is opened at the bottom of the lower end of the collecting plate 17, and a plurality of connecting columns II 21 are evenly arranged on the driving ring 18, and the connecting columns II 21 correspond to the collecting plate 17. One end of the connecting member 19 is connected to the connecting column I 20, and the other end is connected to the connecting column II 21; a plurality of groups of slider rail structures 22 are arranged between the driving ring 18 and the lower support ring 16, and the plurality of groups of slider rail structures 22 are evenly arranged along the circumferential direction of the driving ring 18.
