Description

Technical Field

[0001] The invention relates to the technical field of packaging equipment, and in particular to packaging equipment for producing bird's nests. Background Art

[0002] As a precious tonic, bird's nest is very important to its preservation during transportation and storage. In order to prevent bird's nest from getting damp and breeding bacteria or mold, to ensure food safety and hygiene and to facilitate storage for consumers, using heat shrink film to package bird's nest is an effective way.

[0003] The existing bird's nest packaging method is mostly manual heat shrink film packaging with the help of tools. When using tools to pre-package and cut the heat shrink film, due to the special shape of the bird's nest and the extremely uneven edges, it is usually necessary to manually cut multiple times to complete the heat shrink film pre-packaging of a bird's nest, resulting in low overall packaging efficiency; in addition, when using hot air tools to heat the heat shrink film on the surface of the bird's nest, it is difficult to ensure that the heat shrink film is heated evenly, which may cause the thickness of the heat shrink film after forming to be inconsistent, and the protective effect of the heat shrink film on the bird's nest may be reduced, thereby failing to provide reliable moisture-proof and protective effects for the bird's nest.

[0028] like Figures 1 to 5 As shown, an embodiment of the present invention provides a packaging device for bird's nest production, which includes a processing box, a bracket 110, a bottom film frame, a top film frame, a preform and a cutting knife.

[0029] The interior of the processing box is hollow, and is provided with a heating wire and a temperature control plate. The heating wire can heat the interior of the heating box, and the control plate can adjust the temperature inside the heating box. During the bird's nest packaging process, the internal temperature of the heating box is constant at a first preset temperature, wherein the first preset temperature is a manually set parameter.

[0030] The support 110 is arranged inside the processing box. The support 110 is in a fixed state inside the processing box. A horizontal storage table 120 is arranged on the support 110. A plurality of packing stations are arranged on the storage table 120. Each packing station is a circular groove with an opening facing upward. Each packing station is provided with a partition plate 122. The partition plate 122 divides the circular groove into two parts. Each part can place a bird's nest, so that two bird's nests can be packed at one packing station at the same time. The partition plate 122 can prevent the two bird's nests from contacting each other. Furthermore, the shape of the bird's nest is slightly half a bowl shape. By setting the depth of the circular groove and the height of the partition plate 122, it is ensured that the bird's nest can be placed in the circular groove.

[0031] The bottom film frame is connected to the bracket 110. Specifically, the bottom film frame includes a first winding roller and a first unwinding roller. The first winding roller and the first unwinding roller are arranged in parallel and spaced apart. The first winding roller and the first unwinding roller are both rotatably connected to the bracket 110. The first unwinding roller and the first winding roller are both wound with a first heat shrinkable film 160. In the initial state, the amount of the first heat shrinkable film 160 wound on the first unwinding roller is much greater than the amount of the first heat shrinkable film 160 wound on the first winding roller. The bracket 110 is provided with a first driving motor, and the first driving motor is used to drive the first winding roller to rotate. When the first winding roller rotates, the first heat shrinkable film 160 is gradually wound on the first winding roller, and the first unwinding roller rotates passively. In the initial state, the first heat shrinkable film 160 is laid on the upper surface of the storage table 120. When the first winding roller rotates, the first heat shrinkable film 160 laid on the upper surface of the storage table 120 is replaced. When the temperature in the processing box is the first preset temperature, the first heat shrink film 160 does not shrink, and the first preset temperature does not reach the shrinkage temperature of the first heat shrink film 160. However, the hardness of the first heat shrink film 160 decreases under the first preset temperature environment.

[0032] The top film frame is connected to the bracket 110, and the top film frame has a first state in which it is directly above the storage table 120 and a second state in which it is obliquely above the storage table 120. Specifically, the top film frame includes a sliding frame 140, a second winding roller and a second unwinding roller. The sliding frame 140 is horizontally arranged, and the sliding frame 140 is horizontally slidably connected to the bracket 110. In the initial state, the sliding frame 140 is obliquely above the storage table 120. When the sliding frame 140 slides on the bracket 110, the sliding frame 140 can move to directly above the storage table 120, thereby realizing the switching of the top film frame between the first state and the second state. The second winding roller and the second unwinding roller are arranged in parallel and spaced apart, the axis of the second winding roller is arranged in parallel with the axis of the first winding roller, the second winding roller and the second unwinding roller are both rotatably connected to the sliding frame 140, the second unwinding roller and the second winding roller are both wound with the second heat shrink film 170, in the initial state, the amount of the second heat shrink film 170 wound on the second unwinding roller is much greater than the amount of the second heat shrink film 170 wound on the second winding roller, the sliding frame 140 is provided with a second driving motor, the second driving motor is used to drive the second winding roller to rotate, when the second winding roller rotates, the second heat shrink film 170 is gradually wound on the second winding roller, and the second unwinding roller rotates passively. When the temperature in the processing box is the first preset temperature, the second heat shrink film 170 does not shrink, then the first preset temperature does not reach the shrinking temperature of the second heat shrink film 170, but the hardness of the second heat shrink film 170 decreases under the environment of the first preset temperature. Furthermore, when the first preset temperature is set, it is determined based on the properties of the first heat shrinkable film 160 and the second heat shrinkable film 170 . In the present embodiment, the material and thickness of the first heat shrinkable film 160 and the second heat shrinkable film 170 are the same.

[0033] The preform is used to preform the first heat shrink film 160 when the bird's nest is not placed in the packaging station. The preform is also used to preform the second heat shrink film 170 when the top film frame is in the second state. Specifically, the first heat shrink film 160 and the second heat shrink film 170 do not shrink at the first preset temperature. The hardness of the first heat shrink film 160 and the second heat shrink film 170 decreases under the first preset temperature. Under this condition, the first heat shrink film 160 and the second heat shrink film 170 are preformed to ensure that the first heat shrink film 160 and the second heat shrink film 170 can evenly contact the surface of the bird's nest.

[0034] The cutting knife is used to cut the first heat shrinkable film 160 and the second heat shrinkable film 170 along the outline of the bird's nest when the first heat shrinkable film 160 and the second heat shrinkable film 170 are abutted. Specifically, after the preformed part preforms the first heat shrinkable film 160 and the second heat shrinkable film 170, the bird's nest is placed at the packaging station. At this time, the preformed first heat shrinkable film 160 is below the bird's nest. Then, the sliding frame 140 is driven to move in the horizontal direction of the bracket 110, so that the preformed second heat shrinkable film 1 70 moves to the top of the bird's nest to ensure that the first heat shrink film 160 and the second heat shrink film 170 are in abutment. At this time, the bird's nest is between the first heat shrink film 160 and the second heat shrink film 170, and a cutting knife is used to cut the first heat shrink film 160 and the second heat shrink film 170 simultaneously along the contour of the bird's nest, so as to achieve that the amount of the first heat shrink film 160 and the second heat shrink film 170 used is roughly the same, thereby ensuring that the thickness of the first heat shrink film 160 and the second heat shrink film 170 after heat shrinkage is roughly the same.

[0035] The packaging equipment for producing bird's nests of the present invention sets the interior of the processing box to a first preset temperature when packaging the bird's nests, and lays the first heat shrink film 160 on the storage table 120 under the action of the bottom film frame. At this time, the top film frame is in a second state obliquely above the storage table 120, and the first heat shrink film 160 and the second heat shrink film 170 at the first preset temperature will not shrink. The preformed part preforms the first heat shrink film 160 and the second heat shrink film 170, and then a plurality of bird's nests are placed on the packaging station, and each packaging station can accommodate two bird's nests. Subsequently, the top film rack is moved to the first state directly above the storage table 120, and the preformed second heat shrink film 170 is laid on top of multiple bird's nests. The first heat shrink film 160 and the second heat shrink film 170 are then cut using a cutting knife to ensure that the amount of first heat shrink film 160 and the second heat shrink film 170 used for each bird's nest is the same, thereby ensuring that the thickness of the first heat shrink film 160 and the second heat shrink film 170 after heat shrinkage is roughly the same. In addition, the form of packaging the bird's nest is set to automatic packaging, which improves the packaging efficiency while ensuring good packaging performance.

[0036] In one embodiment, the preform includes a plurality of push blocks 150, a first air guide channel 151 and a second air guide channel 123. The plurality of push blocks 150 are arranged on the top film frame. Specifically, the plurality of push blocks 150 are arranged on the sliding frame 140. When the sliding frame 140 is directly above the storage table 120, each push block 150 is directly above a packaging station. Further, the sliding frame 140 can slide in the vertical direction on the bracket 110. The sliding frame 140 can drive the push blocks 150 into the circular groove. The bracket 110 is provided with a vertical first drive cylinder. The first drive cylinder has a fixed end and a telescopic end. The fixed end of the first drive cylinder is horizontally slidably connected to the bracket 110, and the telescopic end of the first drive cylinder is fixedly connected to the sliding frame 140. When the sliding frame 140 is obliquely above the storage table 120, each push block 150 is in a state of abutting the second heat shrink film 170. Each pushing block 150 is provided with a plurality of first air guiding channels 151, and the sliding frame 140 is provided with a first air source, which can extract gas from the plurality of first air guiding channels 151 at the same time. When the first air source is started, the hardness of the second heat shrinkable film 170 decreases at this time. Under the action of the first air source and the plurality of first air guiding channels 151, the second heat shrinkable film 170 covers the pushing block 150. Furthermore, the lower end face of the pushing block 150 is arranged in an arc shape, and when the second heat shrinkable film 170 covers the pushing block 150, the second heat shrinkable film 170 is gradually preformed.

[0037] Furthermore, a plurality of second air guide channels 123 are provided on the storage table 120, and the second air guide channels 123 are provided at the packaging station. A second air source is provided on the bracket 110, and the second air source can extract gas from the inside of the plurality of second air guide channels 123. When the first heat shrinkable film 160 is laid on the storage table 120, the circular groove is in a state of being blocked by the first heat shrinkable film 160. At this time, the second air source is started, and the second air source extracts the gas in the circular groove through the second air guide channel 123, so that the first heat shrinkable film 160 is laid inside the circular groove, and the first heat shrinkable film 160 is gradually pre-formed.

[0038] In one embodiment, the curvature of the lower end surface of the push block 150 is greater than the curvature of the circular groove. When the push block 150 moves into the circular groove, the push block 150 and the circular groove are in point contact. The first air source can also supply air to the first air guide channel 151. When the bird's nest is placed in the circular groove, the sliding frame 140 moves to the top of the storage table 120, and then the first drive cylinder extends, so that the push block 150 is gradually inserted into the circular groove. By setting the curvature of the push block 150 and the circular groove, the push block and the circular groove are in point contact. At this time, the first air source simultaneously supplies air to multiple first air guide channels 151. At this time, the second heat shrink film 170 gradually breaks away from the push block 150, and the second heat shrink film 170 gradually fits the bird's nest. Furthermore, the temperature of the gas supplied by the first gas source to the inside of the first gas guide channel 151 is a second preset temperature, and the second preset temperature is higher than the shrinkage temperature of the second heat shrinkable film 170, so that the second heat shrinkable film 170 gradually shrinks during the process of laminating the bird's nest.

[0039] In one embodiment, the second air source can also supply air to the second air guide channel 123. When the bird's nest is placed inside the circular groove, the second air source starts to supply air to the second air guide channel 123. The gas entering the second air guide channel 123 causes the first heat shrink film 160 to gradually separate from the circular groove, thereby making the first heat shrink film 160 fit the bird's nest. The temperature of the gas supplied by the second air source to the second air guide channel 123 is a second preset temperature, and the second preset temperature is higher than the heat shrink temperature of the first heat shrink film 160. Further, when the bird's nest is placed inside the circular groove, the first air source and the second air source are started at the same time, and the first air guide channel 151 and the second air guide channel 123 are simultaneously discharged, and the gas between the first heat shrink film 160 and the bird's nest can be squeezed out, and the gas between the second heat shrink film 170 and the bird's nest can be squeezed out, ensuring that the first heat shrink film 160 and the second heat shrink film 170 are in close contact with the bird's nest.

[0040] In one embodiment, the cutting knife includes a knife holder and a knife assembly, and the knife holder is disposed on the top film frame. Specifically, the knife holder is disposed on the sliding frame 140 . There are multiple knife groups, each knife group is arranged corresponding to a push block 150; the knife group includes two first arc knives 210 and two second arc knives 220, the first arc knives 210 and the second arc knives 220 are fixedly connected to the knife holder, the first arc knife 210 is arranged horizontally, and the second arc knife 220 is arranged vertically, the two first arc knives 210 in the same knife group can form a quasi-circular shape, and the two arc knives in the same knife group are arranged in parallel and spaced apart. When the push block 150 is inside the circular groove, the knife group starts to cut the first heat shrink film 160 and the second heat shrink film 170 at the same time, the two first arc knives 210 cut the first heat shrink film 160 and the second heat shrink film 170 along the edge of the circular groove, and the two second arc knives 220 cut the first heat shrink film 160 and the second heat shrink film 170 along the partition plate 122, so that each bird's nest can be independently wrapped.

[0041] In one embodiment, the cutting knife also includes a cutting ring groove 230, and a plurality of cutting ring grooves 230 are provided. The plurality of cutting ring grooves 230 are provided on the storage table 120, and each cutting ring groove 230 is provided corresponding to a packaging station. The first arc knife 210 can be inserted into the cutting ring groove 230. Specifically, the cutting ring groove 230 is provided on the outer side of the circular groove. When cutting the first heat shrinkable film 160 and the second heat shrinkable film 170, the two first arc knives 210 are inserted into the cutting ring groove 230 at the same time. By providing the cutting ring groove 230, it is ensured that the first heat shrinkable film 160 and the second heat shrinkable film 170 are cut off. Furthermore, the thickness of the partition plate 122 is equal to the distance between the two second circular arc knives 220. When cutting the first heat shrink film 160 and the second heat shrink film 170, the second circular arc knife 220 abuts against the partition plate 122, and the relative movement between the second circular arc knife 220 and the partition plate 122 realizes the cutting of the first heat shrink film 160 and the second heat shrink film 170.

[0042] In one of the embodiments, when the first arc knife 210 is inserted into the cutting ring groove 230, the first arc knife 210 and the second arc knife 220 begin to heat up. When the first arc knife 210 and the second arc knife 220 heat up, the first arc knife 210 and the second arc knife 220 simultaneously weld the first heat shrink film 160 and the second heat shrink film 170 together, thereby ensuring that there is no gap between the first heat shrink film 160 and the second heat shrink film 170 that seal a bird's nest.

[0043] In one embodiment, a bird's nest production packaging device further includes a conveyor, which is used to convey unpackaged bird's nests to a packaging station, and can also convey packaged bird's nests away from the packaging station. By providing the conveyor, manual intervention in packaging bird's nests is reduced, ensuring that the process of packaging bird's nests is fully automatic, thereby improving the efficiency and quality of packaging bird's nests.

[0044] In one embodiment, the conveying member includes a conveyor belt 310 and a conveying claw 320. A plurality of conveying claws 320 are provided. The plurality of conveying claws 320 are fixedly connected to the top film frame. Specifically, the plurality of conveying claws 320 are provided on the sliding frame 140. When the sliding frame 140 is located obliquely above the storage table 120, each conveying claw 320 is located directly above a circular groove. The conveyor belt 310 is provided outside the processing box. The processing box has a conveying port connecting the external environment and the interior. When the sliding frame 140 moves to directly above the storage table 120, the plurality of conveying claws 320 move to directly above the conveyor belt 310 through the conveying port. Each conveying claw 320 can clamp two bird's nests on the conveyor belt 310, thereby moving the two bird's nests into the circular groove.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
