Detailed Embodiments

[0021] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will clearly and completely describe the technical solutions in the present utility model in conjunction with the accompanying drawings in the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without any creative work fall within the scope of protection of the present utility model.

[0022] The following will describe Figures 1-3 the packaging material paper scraps suction removal device of the present utility model.

[0023] As Figure 1 shown, in the embodiment of the present utility model, the packaging material paper scraps suction removal device includes: a collection mechanism, a vacuum generator 21, and a first collection box 30. The collection mechanism includes a second collection box 10 and a blowing component. Through holes 101 are respectively provided on the opposite surfaces of the second collection box 10, and the two through holes 101 cooperate to form a moving channel for the packaging material 100. The air outlet of the blowing component is communicated with the inside of the second collection box 10 to blow off the paper scraps on the cut end face of the packaging material 100. The vacuum suction port of the vacuum generator 21 is communicated with the inside of the second collection box 10, and the air outlet of the vacuum generator 21 is communicated with the inside of the first collection box 30. The first collection box 30 is provided with exhaust holes 321. Optionally, there are multiple exhaust holes 321.

[0024] Specifically, the through hole 101 is a strip-shaped hole, and the length of the strip-shaped hole is less than the length of the second collection box 10. The packaging material 100 moves along the moving channel formed by the two through holes 101. The blowing component extends into the second collection box 10. When the cut end face of the packaging material 100 moves into the second collection box 10, the blowing component blows off the paper scraps on the cut end face into the second collection box 10.

[0025] The vacuum generator 21 forms a jet by high-speed jet of compressed air, generates a entrainment effect, thereby obtaining a negative pressure, and sucks the paper scraps in the second collection box 10 into the first collection box 30.

[0026] The blowing component includes an air source and a trachea connected to the air source. The air outlet end of the trachea is communicated with the inside of the second collection box 10 to convey gas into the second collection box 10 to blow off the paper scraps. The air inlet of the vacuum generator 21 is connected to an external air source. It can be understood that the blowing component and the vacuum generator 21 can share the air source or be provided with separate air sources.

[0027] The paper scraps suction device for packaging materials provided by the embodiment of the present utility model can, by setting a blowing component, blow the paper scraps on the cut end surface of the packaging material 100 onto the second collection box when the cut end surface of the packaging material passes through the second collection box, and suck the paper scraps into the first collection box 30 through the negative pressure action of the vacuum generator 21, thus avoiding the paper scraps adhering to the packaging material and affecting the quality of the dairy product contained in the packaging material. Moreover, compared with using a vacuum pump, the vacuum generator 21 has a low use cost and is easy to transform according to the on-site application scenario.

[0028] In a specific embodiment, the paper scraps suction device for packaging materials further includes a compressed air source (not shown in the drawings). Both the blowing component and the vacuum generator 21 are connected to the compressed air source, so that the blowing component and the vacuum generator 21 share the air source, reducing the number of air source settings.

[0029] In an optional embodiment, the blowing component is connected to the compressed air source through a pipeline, and the vacuum generator 21 is connected to the compressed air source through another pipeline. The blowing component and the vacuum generator 21 independently use the compressed air source, and the two do not affect each other. In another optional embodiment, the compressed air source is communicated with the air inlet of the blowing component and the air inlet of the vacuum generator 21 through a tee pipe 22. Wherein, a switch valve 12 is installed on the connection path between the tee pipe 22 and the compressed air source. When the switch valve 12 is opened, the compressed air source can supply air to the blowing component and the vacuum generator 21; when the switch valve 12 is closed, the compressed air source cannot supply air to the blowing component and the vacuum generator 21.

[0030] As Figure 1 and Figure 2 shown, in the embodiment of the present utility model, the blowing component includes a blow pipe 11 and a nozzle 14. The air inlet of the blow pipe 11 is connected to the compressed air source, and the nozzle 14 is installed at the air outlet of the blow pipe 11. The nozzle 14 is located in the second collection box 10.

[0031] One end of the blow pipe 11 extends into the second collection box 10 and the nozzle 14 is installed. The air outlet direction of the nozzle 14 is parallel to the extension direction of the cut end surface of the packaging material 100.

[0032] Further, in order to improve the efficiency of blowing off the paper scraps, a plurality of nozzles 14 are provided. Specifically, the blow pipe 11 is a multi-branch pipe, one of the branch pipes is used as an air inlet pipe and is connected to the compressed air source, and the end parts of the other branch pipes used as air outlet pipes are respectively installed with nozzles 14. The plurality of nozzles 14 can be annularly arranged along the inner wall of the second collection box 10, or can be oppositely arranged on both sides of the second collection box 10. When the plurality of nozzles 14 are oppositely arranged on both sides of the second collection box 10, the nozzles 14 on both sides can be symmetrically arranged or staggered.

[0033] For example, air nozzles 14 are respectively arranged on opposite sides of the second collection box 10. Specifically, the blowing pipe 11 is a three-way pipe, including a first pipeline, a second pipeline and a third pipeline. The first pipeline communicates with the first side of the second collection box 10, the second pipeline communicates with the second side of the second collection box 10, and the third pipeline is connected to a compressed air source. Among them, the first side and the second side are arranged oppositely. When the compressed air source is connected to the air inlet of the blowing assembly through the three-way pipe 22, the third pipeline is connected to one interface of the three-way pipe 22. In this embodiment, a part of the gas entering the third pipeline enters one side of the second collection box 10 through the first pipeline, and the other part enters the other side of the second collection box 10 through the second pipeline. When the cut of the packaging material 100 enters the second collection box 10, the first pipeline and the second pipeline blow off the paper scraps on the cut at the same time, so as to improve the efficiency of removing paper scraps.

[0034] The shape of the air nozzle 14 matches the shape of the packaging material 100. Specifically, there are two types of packaging materials 100, one is a roll of paper strips and the other is a paper box. For the roll of paper strips, its cut is one edge; while for the paper box, the cut is quadrilateral and has four edges. Since the shapes of the packaging materials 100 are different, the shapes of their cuts are also different, and different shapes of air nozzles 14 need to be set to ensure the purging effect. For example, for the roll of paper strips, the shape of the air nozzle 14 can be square or circular, so that the air flow can be gathered into a stream and blown towards the cut to ensure the purging effect. For the paper box, since its cut has four edges, the air flow needs to be dispersed to increase the air outlet area of the air nozzle 14, so that the gas can be blown to each edge. At this time, the end of the air nozzle 14 facing the cut is an expansion port to increase the purging area. Optionally, the shape of the air nozzle 14 can be funnel-shaped or rectangular, and the long side of the rectangle is parallel to the opposite cut.

[0035] To adjust the amount of gas distributed from the compressed air source to the blowing assembly and the vacuum generator 21, a pressure regulating valve 13 is installed on the connection path between the three-way pipe 22 and the blowing assembly.

[0036] As Figure 1 shown, the pressure regulating valve 13 is arranged on the blowing pipe 11. Of course, a pressure regulating valve can also be installed on the connection path between the three-way pipe 22 and the vacuum generator 21. Or, a control valve is arranged on the connection path between the three-way pipe 22 and the vacuum generator 21 and / or on the connection path between the three-way pipe 22 and the blowing assembly to control the on-off of the corresponding connection path.

[0037] As Figure 1As shown in the figure, the vacuum generator 21 is connected to the second collection box 10 through the suction pipe 20. Optionally, the suction pipe 20 is a multi-branch pipe to improve the dust collection efficiency. For example, the suction pipe 20 is a three-branch path, including: a main pipe, a fourth pipe 201 and a fifth pipe. The main pipe is connected to the vacuum generator 21, and the fourth pipe and the fifth pipe are respectively communicated with the opposite sides of the second collection box 10. Under the action of negative pressure, the paper scraps enter the main pipe through the fourth pipe 201 and the fifth pipe, and then enter the first collection box 30.

[0038] There is liquid in the first collection box 30. Under the action of the vacuum generator 21, the paper scraps are sucked into the first collection box 30, and the contained liquid is used to prevent the paper scraps from flying around.

[0039] As Figure 1 shown, in the embodiment of the present utility model, the first collection box 30 includes: a box body 31 and a cover body 32. The box body 31 and the cover body 32 are detachably connected. For example, the cover body 32 is hinged to the box opening of the box body 31; or, the cover body 32 is buckled on the box opening of the box body 31. Among them, the box body 31 is connected to the vacuum generator 21, there is liquid in the box body 31, and the cover body 32 is provided with an exhaust hole 321.

[0040] As Figure 1 shown, a partition 33 is installed in the first collection box 30. As Figure 3 shown, there is a gap between a part of the outer edge of the partition 33 and the inner wall of the first collection box 30. Or, the outer periphery of the partition 33 fits with the inner wall of the first collection box 30, and the partition 33 is provided with ventilation holes to ensure that the gas can flow smoothly in the first collection box 30.

[0041] Specifically, due to the large airflow impact force at the air outlet of the vacuum generator 21, the partition 33 is arranged in the box body 31, which can prevent the liquid from splashing and avoid the paper scraps from flying out.

[0042] Furthermore, the number of the partitions 33 can be multiple, and the multiple partitions 33 are arranged in sequence along the height direction of the first collection box 30, and adjacent two partitions 33 are arranged staggeredly to optimize the blocking effect.

[0043] As Figure 1 shown, in the embodiment of the present utility model, an annular protection member 40 is provided at the inlet and / or outlet of the moving channel.

[0044] Among them, the annular protection member 40 can be located on the inner wall surface or the outer wall surface of the second collection box 10. As Figure 1 shown, an annular protection member 40 is respectively provided on the outer surface of the top wall and the outer surface of the bottom wall of the second collection box 10. Preferably, the annular protection member 40 is a flexible protection member. For example, the annular protection member 40 is a silica gel member or a polyethylene member.

[0045] The cavity of the annular protective member 40 allows the packaging material 100 to pass through. The annular protective member 40 protrudes at the inlet and / or outlet of the moving channel, which can not only fix the packaging material 100, but also prevent the packaging material 100 from being scratched by means of the annular protective member 40.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the present invention in each embodiment.
