Fig. 1 to 8 schematically show an embodiment of a dust collecting mechanism for a three-dimensional packaging sheet spreading device according to the present invention.

As shown in fig. 4 to 8, the dust collecting mechanism for the three-dimensional wrapping sheet spreading device includes a support plate 40 and a housing unit; wherein, the supporting plate 40 is fixedly arranged relative to the frame 20 of the three-dimensional packaging sheet unfolding device, the supporting plate 40 is arranged below a clamping position of a stretching mechanism 30 of the three-dimensional packaging sheet unfolding device for clamping the packaging sheet, the stretching mechanism 30 is generally realized by at least one group of roller structures 300 arranged at a feed inlet and at least one group of roller structures 300 arranged at a discharge outlet 2003, each group of roller structures 300 comprises rollers 301 arranged at the upper part and rollers 301 arranged at the lower part, and the rollers 301 at the upper part and the rollers 301 at the lower part of each group of roller structures 300 clamp the packaging sheet in a way that the outer diameters are abutted against each other; a containing structure which penetrates the supporting plate 40 up and down is integrally formed or processed on the supporting plate 40, and the containing structure can avoid the stretching mechanism 30; the receiving unit is movably disposed with respect to the frame 20, or the receiving unit is detachably disposed on the frame 20, is disposed below the supporting plate 40 and the stretching mechanism 30, and is integrally formed or processed with a first opening disposed toward the first opening. In the present invention, the accommodating structure is a structure that can accommodate the stretching mechanism 30 and can accommodate at least a part of the stretching mechanism 30 and penetrate the support plate 40, for example, a common structure that penetrates up and down, such as the through groove 400 or the through hole.

As a first embodiment of the support plate 40, as shown in fig. 5, 7 and 9, the receiving structure is implemented as a through groove 400 integrally formed or machined on the support plate 40 and capable of avoiding at least the roller 301 at the discharge end of the stretching mechanism 30. Illustratively, such a through slot 400 may be obtained by configuring the support plate 40, for example, as shown in fig. 5, 7 and 9, the support plate 40 includes a first connecting plate 41 for being disposed on the feeding end 201 of the frame 20, a second connecting plate 42 for being disposed on the discharging end 202 of the frame 20, and a connecting rod 43 for connecting the first connecting plate 41 and the second connecting plate 42, and the adjacent connecting rod 43, the first connecting plate 41 and the second connecting plate 42 enclose the through slot 400. For example, the cross section of the connecting rod 43 may be circular or square.

As a second embodiment of the support plate 40, as shown in fig. 10, the support plate 40 may be constructed in reference to the first embodiment of the support plate 40, including connecting the first connection plate 41 and the second connection plate 42 by a connection rod 43. The difference from the support plate 40 of the first embodiment is mainly in the specific shape of the connecting rod 43. Specifically, the top of the connecting rod 43 is the edge 431 thereof, so that the connecting rod 43 is in line contact with the packaging sheet supported by the connecting rod through the edge 431, and the top of the connecting rod 43 is the edge 431 and can be implemented by providing inclined surfaces 432 on the left and right sides of the edge 431 or providing the inclined surfaces 432 on only one side (left side or right side) of the edge 431 so as to avoid dust deposition on the supporting plate 40.

As a third embodiment of the supporting plate 40, as shown in fig. 11, the receiving structure provided on the supporting plate 40 includes a first through hole 401 and a second through hole 402 integrally formed or machined on the supporting plate 40, wherein the first through hole 401 is provided to allow at least a portion of the discharge end of the stretching mechanism 30 to protrude thereinto. Preferably, at least one of the first through holes 401 and the second through holes 402 is provided in plurality, and the first through holes 401 are distributed in a staggered manner on the support plate 40, the second through holes 402 are distributed in a staggered manner on the support plate 40, or the first through holes 401 and the second through holes 402 are distributed in a staggered manner, so that the dust deposited on the support plate 40 can be moved to fall into the first through holes 401 or the second through holes 402 by the driving of the packaging sheet.

As a fourth embodiment of the support plate 40, as shown in fig. 12, it differs from the first embodiment of the support plate 40 mainly in that: the angle between the end of the connecting rod 43 close to the second connecting plate 42 and the discharging direction on the horizontal plane is greater than 0 ° and less than 90 °, that is, the end of the connecting rod 43 close to the second connecting plate 42 is obliquely arranged in the horizontal plane, so that the dust deposited on the supporting plate 40 can be driven by the packaging sheet to move to fall into the first through hole 401 or the second through hole 402.

Regardless of the embodiment of the support plate 40, it is preferred that the side of the support plate 40 near the discharge end 202 of the three-dimensional wrapping sheet dispenser be inclined downwardly as shown in fig. 4 and 9 to 11. So as to facilitate the discharge of the packaging sheet.

As one of the embodiments of the receiving unit, as shown in fig. 4 to 8, the receiving unit is implemented as a drawer fitted on the rack 20.

In the using process of the three-dimensional packaging sheet unfolding device, the rotating speed of the roller structure 300 of the feeding port is set to be smaller than that of the roller structure 300 of the discharging port 2003, namely, the packaging sheet clamped between the feeding port and the discharging port 2003 can be stretched through the speed difference between the roller structure 300 of the feeding port and the roller structure 300 of the discharging port 2003. According to the invention, the accommodating unit with the upward first opening is arranged below the stretching mechanism 30, dust generated when the stretching mechanism 30 stretches the packaging sheet can fall into the accommodating unit through the first opening, and the accommodating unit is used for accommodating the dust generated when the packaging sheet is stretched; moreover, because the supporting plate 40 is arranged below the clamping position of the stretching mechanism 30 for clamping the packaging sheet, the supporting plate 40 is provided with an accommodating structure for accommodating the stretching mechanism 30 and penetrating through the supporting plate from top to bottom, and because the accommodating unit is also arranged below the supporting plate 40, dust generated by stretching the packaging sheet can directly fall into the accommodating unit from the accommodating structure or fall on the supporting plate 40, and then the packaging sheet is driven by the stretched packaging sheet to move to the accommodating structure and fall into the accommodating unit from the accommodating structure, so that the dust is accommodated by the accommodating unit; moreover, since the support plate 40 separates the packaging sheet from the accommodating unit, the possibility that the dust accommodated in the accommodating unit is lifted by the movement of the packaging sheet can be greatly reduced; the dust can be prevented from being brought out of the three-dimensional packaging sheet unfolding device due to the fact that the packaging sheet is in contact with dust stored in the containing unit, and the prepared three-dimensional packaging sheet is large in dust carrying amount and poor in quality; when the dust that holds in the unit holds is more, can also remove the relative frame 20 of unit that holds to under the condition of not dismantling frame 20, the dust that holds in the unit is held in the clearance, and operation process convenient and fast, and the clearance process need not with the help of high-pressure draught, and the production environment can not be blown up and be polluted because of the dust that holds in the unit is held by high-pressure draught.

As an example of the tolerance structure, the tolerance structure is a through groove 400 integrally formed or machined on the support plate 40, and the through groove 400 is provided in plurality. Preferably, at least the through slots 400 of the outfeed 2003 are capable of avoiding the rollers 301 located therein. In some embodiments, the through grooves 400 of the inlet and outlet 2003 can avoid the rollers 301 located therein, and of course, the through grooves 400 may also be disposed at a position of the support plate 40 located between the inlet and outlet 2003, the through grooves 400 between the inlet and outlet 2003 may be relatively independent from the through grooves 400 at the inlet and outlet 2003, and the through grooves 400 between the inlet and outlet 2003 may be distributed in a regular array or randomly, and the through grooves 400 disposed between the inlet and outlet 2003 are mainly for facilitating the dust generated during the stretching process of the packaging sheet to fall into the accommodating unit, and reducing the dust deposited on the support plate 40. As a preferred embodiment of the containment structure, as shown in fig. 5, the containment structure is a through slot 400 integrally formed or machined in the support plate 40, and the through slot 400 extends from the feed end 201 of the stereoscopic packaging sheet material unwind to the discharge end 202 of the stereoscopic packaging sheet material unwind. When the stretching mechanism 30 includes the roller structure 300 of the inlet and the roller structure 300 of the outlet 2003, the through groove 400 extends at least from the position of the roller structure 300 of the inlet to the position of the roller structure 300 of the outlet 2003, so that most of the dust generated when the wrapping sheet between the inlet and the outlet 2003 is stretched can fall into the containing unit through the through groove 400, only a small amount of dust is deposited on the support plate 40, and most of the dust deposited on the support plate 40 moves to the through groove 400 along with the moving wrapping sheet and then falls into the containing unit.

As one of the embodiments of the accommodating unit, as shown in fig. 1 to 8, the accommodating unit includes at least one of a first drawer 51 and a second drawer 52. First drawer 51 and/or second drawer 52 may be disposed on either side of rack 20 as desired. However, since the stretching mechanism 30 is generally disposed on both sides of the frame 20 in the stretching direction, and the driving unit 33 for driving the stretching mechanism 30 to move is also generally disposed on the side of the frame 20 where the stretching mechanism 30 is disposed, it is preferable that the first drawer 51 and the second drawer 52 are disposed to be capable of reciprocating in the stretching direction of the stretching mechanism 30 in order to avoid the problem that the first drawer 51 and the second drawer 52 disposed on the bracket affect the operation of the stretching mechanism 30 and the driving unit 33, and to avoid the problem that the volume of the device is large due to mutual escape of the mechanisms because the stretching mechanism 30, the driving unit 33, the first drawer 51 and the second drawer 52 are disposed on the same side of the frame 20; a first drawer 51 is fitted on the frame 20 and arranged to be able to move out of the frame 20 from the feed end 201 of the three-dimensional wrapping sheet unrolling device; a second drawer 52 is fitted to the frame 20 and is arranged to be able to move out of the frame 20 from the outfeed end 202 of the three-dimensional packaging sheet material unrolling device. Therefore, the dust in the drawer can be cleaned conveniently, and the structure compactness of the three-dimensional packaging sheet unfolding device provided with the dust collecting mechanism can be kept.

Since the stretching mechanism 30 of the three-dimensional packaging sheet material unfolding device also drives the packaging sheet material to move in the direction from the feeding end 201 to the discharging end 202 when stretching the packaging sheet material, so that the first drawer 51 and the second drawer 52 have a tendency to move in the direction from the feeding end 201 to the discharging end 202 during the operation of the three-dimensional packaging sheet material unfolding device, in order to avoid the first drawer 51 and the second drawer 52 from moving during the operation of the three-dimensional packaging sheet material unfolding device, as a preferred embodiment of the first drawer 51, as shown in fig. 2 and 5, the outer surface of the first drawer 51 extends to the outer side of the side wall of the first drawer 51, and the part of the outer surface of the first drawer 51 extending out of the outer side of the side wall thereof can abut against the end surface of the feeding end 201 of the frame 20 when the first drawer 51 is pushed into the frame 20. As a preferred embodiment of the second drawer 52, the second drawer 52 is configured to be capable of being magnetically attracted to the rack 20, for example, an outer surface of the second drawer 52 extends to an outer side of a side wall of the second drawer 52, and a portion of the outer surface of the second drawer 52 extending out of the outer side of the side wall thereof can abut against an end surface of the discharge end 202 of the rack 20 when the second drawer 52 is pushed into the rack 20, at least one of the abutting positions of the end surfaces of the second drawer 52 and the discharge end 202 is provided with a magnet 221, and the other abutting position is provided with either a magnet 221 or a ferromagnetic member capable of being magnetically attracted, and at least one of the rack 20 or the second drawer 52 can be made of a material capable of being magnetically attracted.
