Specifically, as shown in fig. 1 to 5, a packaging apparatus according to an embodiment of the present invention is shown, and the packaging apparatus includes a frame 10, a pallet assembly 11, a first folio assembly 12, a support frame 13, a shelf plate 14, a connecting plate 15, a connecting plate driving mechanism 16, a clamping assembly 17, and a second folio assembly 18. The frame 10 is a structural frame of the device, and can be regarded as a basic carrier for installing other components and parts, such as a fixed supporting plate assembly 11, a first folding assembly 12, a supporting frame 13, a frame plate 14, a connecting plate 15, a connecting plate driving mechanism 16, a clamping assembly 17, a second folding assembly 18 and the like. The frame 10 mainly includes a metal frame made of aluminum alloy or other metal section bars through welding or bolt connection, and may further include an enclosure plate surface of a metal plate section bar arranged outside the metal frame. The metal frame can be freely and coordinately arranged according to the arrangement positions of different components and parts, and the components can normally operate without interference, so that the specific shape and structure of the frame 10 are not limited in the embodiment of the invention.

Of course, universal wheels can be arranged at the bottom of the metal frame for moving and carrying. Where the frame 10 is mentioned in the embodiments that follow, the frame 10 may be considered to refer to a metal frame for ease of understanding.

As shown in fig. 6-10, is a separate schematic of the pallet assembly 11. The supporting plate assembly 11 is mounted on the frame 10, can be fastened by bolts and the like, and is kept relatively static with the frame 10, and the supporting plate assembly 11 can also be connected with the frame 10 in a sliding manner through a sliding block and a guide rail. The pallet assembly 11 has a carrying surface parallel to the horizontal plane on which the wrappers and the target products to be packaged can be placed. For a clearer understanding of the bearing surface of the embodiment of the present invention, in conjunction with the example of fig. 6, the bearing surface may be the illustrated plane S, which is a solid surface on the pallet assembly 11. A wrapper may be laid flat on the carrying surface over which the hamburger or other target product to be packaged is placed.

The first folding assemblies 12 are assemblies for folding the packing paper along a first direction, and two first folding assemblies 12 connected to the frame in the packing device respectively fold the packing paper from a first side and a second side opposite to the supporting plate assembly 11, so that the first folding is realized. As shown in fig. 1 to 5, the two first pair of folding assemblies 12 may be folded in the X direction to roll the wrapper to wrap the target product.

After the first folding process, the packaging paper needs to be folded from another direction to completely wrap the target product. Therefore, the wrapping paper and the target product can be clamped and lifted by means of the clamping assembly 17 connected with the connecting plate 15, under the action of the connecting plate driving mechanism 16, the connecting plate driving mechanism 16 drives the connecting plate 15 to move along the direction vertical to the bearing surface, namely the connecting plate 15 moves along the Z direction shown in the figure, and simultaneously drives the clamping assembly 17 connected with the connecting plate 15 to move up and down along the Z direction. The link plate driving mechanism 16 is a mechanism that can drive the driving link plate 15 to move linearly in the Z direction. Illustratively, the connecting plate driving mechanism 16 may be any one of a pneumatically controlled telescopic cylinder, a motor-driven rack-and-pinion mechanism, a motor-driven lead screw nut mechanism, or a motor-driven synchronous belt driving mechanism, a power source of the connecting plate driving mechanism 16 is fixed on the frame 10, and a linear motion component of the connecting plate driving mechanism 16 is fixedly connected to the connecting plate 15. In the embodiment of the present invention, the specific type of the connecting plate driving mechanism 16 is not limited, and regarding the specific connection manner of the connecting plate driving mechanism 16, a person skilled in the art can easily perform connection according to the specific mechanism type, and details are not described here.

Subsequently, two second folding assemblies 18 are moved along the line connecting the third and fourth opposite sides of the tray assembly 11 to fold the wrapping paper from the Y-direction as shown, thereby completely wrapping the target product. Therefore, it can be understood that, when it is necessary to achieve complete wrapping, at least two paper folding packaging processes are required, wherein the two paper folding packaging processes are respectively in an X direction formed by connecting lines of the first side and the second side of the pallet assembly 11, and a Y direction formed by connecting lines of the third side and the fourth side of the pallet assembly 11, which may be two orthogonal directions. The first and

second folio assemblies

12, 18 respectively fold the wrapper from different directions to simulate manual wrapping to complete the product wrapping process.

Alternatively, referring to fig. 6 to 10, the pallet assembly 11 includes a first pallet 111, a second pallet 112, and a pallet driving mechanism 113;

the first supporting plate 111 and the second supporting plate 112 are both connected with the rack 10 in a sliding manner, and the first supporting plate 111 and the second supporting plate 112 are arranged oppositely;

the supporting plate driving mechanism 113 is fixedly connected to the frame 10, and the supporting plate driving mechanism 113 drives the first supporting plate 111 and the second supporting plate 112 to move closer to or away from each other.

Specifically, in one embodiment, as shown in fig. 6 to 10, the above-mentioned tray assembly 11 may include a first tray 111 slidably connected to the frame 10, a second tray 112, and a tray driving mechanism 113 fixed to the frame 10. The first and

second support plates

111 and 112 may be strip-shaped elements, and are disposed in parallel and opposite to each other, and the upward planes of the two support plates jointly form a bearing surface for placing wrapping paper and a target product to be packaged. Each of the pallets can slide and translate relative to the frame 10, as shown in fig. 6, when the first pallet 111 and the second pallet 112 are driven by the pallet driving mechanism 113 to approach each other along a first direction, i.e., the illustrated X direction, the distance between the two is reduced, and at this time, a target product with a small size and a small volume can be placed on the carrying surface of the pallet assembly 11. When the first and

second pallets

111 and 112 are driven by the pallet driving mechanism 113 to move away from each other along a first direction, i.e., the illustrated X direction, the distance between the two pallets increases, and at this time, a target product with a larger size and a larger volume can be placed on the carrying surface of the pallet assembly 11. Therefore, the size of the bearing surface of the supporting plate assembly 11 can be flexibly adjusted by the two slidable supporting plates, and target products with different sizes can be borne and placed.

Alternatively, referring to fig. 8, the pallet drive mechanism 113 includes a first drive motor 1131, a bidirectional lead screw 1132, a first push plate 1133, and a second push plate 1134;

the internal threads of the first push plate 1131 and the internal threads of the second push plate 1132 have opposite directions of rotation.

Specifically, the pallet driving mechanism 113 is a mechanism that can drive the first pallet 111 and the first pallet 112 to move linearly in the X direction, similarly to the aforementioned connecting plate driving mechanism 16. The supporting plate driving mechanism 113 may be any one of a pneumatically controlled telescopic cylinder, a motor-driven rack-and-pinion mechanism, a motor-driven lead screw nut mechanism, or a motor-driven synchronous belt driving mechanism. The pallet driving mechanism 113 may be provided with two pallets for driving the first pallet 111 and the first pallet 112 independently, or may be provided with only one pallet for driving the first pallet 111 and the first pallet 112 simultaneously.

In one embodiment, as shown in fig. 8, the pallet driving mechanism 113 may include a first driving motor 1131, a bidirectional lead screw 1132, a first push plate 1133 and a second push plate 1134. It can be understood that, two-way lead screw 1132 is provided with both ends and revolves to opposite screw thread, first push plate 1133 and second push plate 1134 are two push plates that are provided with the opposite internal screw thread of revolve to, thereby, first push plate 1133, after second push plate 1134 and two-way lead screw 1132 threaded connection, when first driving motor 1131 rotates and drives two-way lead screw 1132 and rotate, first push plate 1133 and second push plate 1134 are close to each other or keep away from along the axial of two-way lead screw 1132, because first push plate 1133 and first layer board 111 fixed connection, second push plate 1134 and second layer board 112 fixed connection, consequently, utilize the motion that above-mentioned two-way lead screw 1132 can drive first layer board 111 and second layer board 112 simultaneously, compare in respectively independent drive, the structure volume of spare part is less, occupation space is less and drive efficiency is higher.

Optionally, referring to fig. 6-10, the pallet assembly 11 further comprises a first rotary drive 114, a first clamp plate 115, a second rotary drive 116, and a second clamp plate 117;

the first rotary driving element 114 is fixedly connected with the first supporting plate 111, an output end of the first rotary driving element 114 is fixedly connected with the first clamping plate 115, and the first rotary driving element 114 drives the first clamping plate 115 to move to a position parallel to or perpendicular to the bearing surface;

the second rotary driving element 116 is fixedly connected with the second supporting plate 112, and the output end of the second rotary driving element 116 is fixedly connected with the second clamping plate 117; the second rotary driving member 116 drives the second clamping plate 117 to move to a position parallel or perpendicular to the bearing surface;

when the first clamping plate 115 and the second clamping plate 117 are perpendicular to the bearing surface, the first clamping plate 115 and the second clamping plate 117 protrude from the bearing surface.

Specifically, in one embodiment, as shown in fig. 6 to 10, the pallet assembly 11 further includes a first rotary driver 114, a first clamping plate 115, a second rotary driver 116, and a second clamping plate 117. The first and second

rotary driving members

114 and 116 may be driving members such as motors or rotary cylinders, and the motion form of the output end is circular rotation motion.

The first rotary driving member 114 is fixedly connected to the first supporting plate 111, and an output end of the first rotary driving member 114 drives the first clamping plate 115 to rotate, that is, the first clamping plate 115 can rotate relative to the first supporting plate 111. Similarly, the second clamp plate 117 can rotate relative to the second blade 112. According to the actual structure size and the assembling relationship, when the first clamping plate 115 and the second clamping plate 117 are designed to be perpendicular to the bearing surface, the first clamping plate 115 and the second clamping plate 117 protrude out of the bearing surface. It can be understood that, in this state, the first clamping plate 115 and the second clamping plate 117 can force the wrapping paper on the bearing surface to be turned over in advance along the direction perpendicular to the bearing surface, i.e. the Z direction, so that the wrapping paper can be pre-folded, positioned and clamped, and the difficulty of directly folding the flat wrapping paper can be reduced.

Optionally, referring to fig. 6, the packaging device further comprises a first vacuum generator, the carrying surface is provided with a first suction hole 118, and the first suction hole 118 is communicated with the first vacuum generator.

Specifically, in one embodiment, as shown in fig. 6, the packaging device disclosed in the embodiment of the present invention may further include a first vacuum generator (not shown in the figure), and the first vacuum generator may be a vacuum pump generating a negative pressure vacuum condition.

Illustratively, the first suction holes 118 may be a plurality of openings uniformly arranged in an array on the support surface to provide a tight suction fit of the wrapper against the support surface to prevent misalignment of the wrapper during movement of the first vacuum generator.

Alternatively, referring to fig. 11 to 20, the first folio assembly 12 includes a bottom folio board 121, a sliding plate 122, a sliding plate driving mechanism 123, a first folio board 124, a second folio board 125, and a folio board driving mechanism 126;

the paper folding bottom plate 121 is connected with the frame 10;

the sliding plate driving mechanism 123 is fixedly connected with the paper folding bottom plate 121, the output end of the sliding plate driving mechanism 123 is connected with the sliding plate 122, and the sliding plate driving mechanism 123 drives the sliding plate 122 to move along the first direction;

the paper folding board driving mechanism 126 is fixedly connected to the sliding plate 122, an output end of the paper folding board driving mechanism 126 is connected to the first paper folding board 124 and the second paper folding board 125, and the paper folding board driving mechanism 126 drives the first paper folding board 124 and the second paper folding board 125 to move along the second direction.

Specifically, in one embodiment, as shown in fig. 11-14, a structural schematic of the first folio component 12 is shown. The first folio assembly 12 may include a bottom folio board 121, a slide plate 122, a slide plate drive mechanism 123, a first sheet folding plate 124, a second sheet folding plate 125, and a sheet folding plate drive mechanism 126. The folding base 121 serves as a carrier for the slide 122, the slide driving mechanism 123, the first folding board 124, the second folding board 125 and the folding board driving mechanism 126 to be mounted thereon for sliding connection or fixed connection with the frame 10. When the bottom folding plate 121 is slidably connected to the frame 10, the entire first folding unit 12 can move in translation relative to the frame 10.

Referring to fig. 12, the slide plate driving mechanism 126 is fixed on the paper folding base plate 121, and when the slide plate driving mechanism 126 operates, the output end of the slide plate driving mechanism drives the slide plate 122 to move along a first direction, i.e., the X direction shown in the figure, relative to the paper folding base plate 121. Meanwhile, since the paper folding board driving mechanism 126 is fixed on the sliding plate 122, the sliding plate 122 also drives the paper folding board driving mechanism 126 to move synchronously, and in addition, the paper folding board driving mechanism 126 drives the first paper folding board 124 and the second paper folding board 125 to move along the second direction, i.e., the Y direction in the figure. Therefore, with the bottom folding plate 121 as a reference, the first folding assembly 12 can realize two different directions of movement of the first folding plate 124 and the second folding plate 125 relative to the bottom folding plate 121.

With reference to the schematic diagrams of fig. 15 to 20, the two first folding assemblies 12 in the packaging device have the same structure, and the two first folding assemblies 12 are respectively disposed on two sides of the pallet assembly 11. The two first folding members 12 are actuated simultaneously to fold the wrapper from the first and second sides of the pallet assembly 11 respectively. For either first folding assembly 12, and as shown in connection with the illustration of FIG. 18, the wrapper may be folded as the first and second tucking flaps 124, 125 are moved in a first direction. When the first and

second folding plates

124 and 125 move in the second direction, the packaged product may be separated. Therefore, the combination of the two directions of movement can complete the first automatic folding and packaging process.

In addition, similar to the connecting plate driving mechanism 16, the sliding plate driving mechanism 126 and the paper folding plate driving mechanism 126 may be any one of a pneumatically controlled telescopic cylinder, a motor-driven gear rack mechanism, a motor-driven lead screw nut mechanism or a motor-driven synchronous belt driving mechanism.
