Description

Technical Field

[0001] The present invention relates to the technical field of food processing, and specifically to a food packaging device for food processing. Background Art

[0002] A sealing machine is a machine that seals containers filled with products. After the products are loaded into packaging containers, in order to seal and preserve the products, maintain the product quality, and avoid product loss, the containers need to be sealed, and this operation is completed by a sealing machine. After food processing, the food is generally transferred into a packaging bag or other packaging containers, and then the sealing machine is used to perform packaging processing on the packaging bag or packaging container.

[0003] Generally, a sealing machine consists of components such as a frame, a speed reduction and speed regulation transmission mechanism, a sealing and printing mechanism, a conveying device, and an electrical and electronic control system. When a packaged item is placed on the conveyor belt, the sealing part of the bag is automatically fed between two running sealing belts and brought into the heating area. The heat of the heating block is transmitted to the sealing part of the bag through the sealing belt, causing the film to soften by heating. Then, through the cooling area, the surface temperature of the film is appropriately reduced. Then, through rolling by a knurling wheel (or printing wheel), the upper and lower plastic films of the sealing part are adhered together and a net pattern (or printed logo) is pressed out. Then, the sealed packaging bag is sent out of the machine by a guiding rubber belt and the conveyor belt to complete the sealing operation.

[0004] However, for many existing sealing machines used in small workshops or individual stores, most of them manually place the packaging containers into the packaging mold cavity of the sealing machine by hand, and then manually or by machine inject liquid foods into the containers, and then the sealing machine performs the packaging operation, or directly manually places the containers filled with liquid foods into the packaging mold cavity and then the sealing machine packages them. Such sealing machines are generally directly exposed to the air, and due to financial problems, a dust-free or sterile environment cannot be established for operation, so the hygiene of the packaged food cannot be guaranteed. People with low immunity are prone to health and safety problems after eating, and the shelf life of the packaged food is too short, easily causing food waste. At the same time, loading into the container and unloading the product are mostly manual operations, with low automation, and manual operations are also prone to hygiene problems.

[0005] Therefore, a food packaging device for food processing is proposed. Summary of the Invention

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1 to 11 , the present invention provides a food packaging device for food processing, and the technical solution is as follows:

[0039] A food packaging device for food processing, comprising:

[0040] A working platform 1, which is fixedly installed on the ground;

[0041] An installation housing 2, an installation housing 2 is fixedly installed on the working platform 1, two third cylinders 10 are vertically and fixedly installed above the installation housing 2, the output ends of the two third cylinders 10 are fixedly installed on the upper heat-sealing knife 11, a lower heat-sealing knife 12 is arranged below the upper heat-sealing knife 11, the lower heat-sealing knife 12 and the upper heat-sealing knife 11 are connected by four bolts 13, and four springs 14 are evenly wound around the four bolts 13. The springs 14 are located between the upper heat-sealing knife 11 and the lower heat-sealing knife 12. Two fourth cylinders 15 are fixedly installed behind the installation housing 2, motors 16 are fixed on the output ends of the two fourth cylinders 15, the output rods of the two motors 16 extend into the installation housing 2, the output rod of one motor 16 is wound with an encapsulation film 17, and the output rod of the other motor 16 is used for winding the waste film 18 after being discarded;

[0042] A cylinder 1 is horizontally installed on the working platform 1. A sealing plate 4 that cooperates with the installation shell 2 is fixedly installed at the output end of the cylinder 1. A packaging table 5 is fixedly installed on the sealing plate 4. The sealing plate 4 and the packaging table 5 can be driven by the cylinder 1 to cooperate with the installation shell 2 to form a sealed space during food packaging. A packaging mold 6 is installed on the packaging table 5. A packaging can 31 for packaging is placed in the packaging mold 6. A cylinder 2 7 is horizontally and fixedly installed on the sealing plate 4. A partition plate 8 is fixedly installed at the output end of the cylinder 2 7. A material pipe 9 is fixedly installed on the partition plate 8, and the material pipe 9 passes through the sealing plate 4.

[0043] After the packaging can 31 is placed in the packaging mold 6, the cylinder 1 will push the sealing plate 4 and the packaging table 5 into the installation shell 2. Subsequently, the cylinder 2 7 extends towards the packaging mold 6, driving the partition plate 8 to extend at the same time. The material pipe 9 on the partition plate 8 will inject liquid food into the packaging can 31. After injection, the cylinder 2 7 drives the partition plate 8 and the material pipe 9 to retract. Subsequently, the two cylinders 4 15 extend towards the installation shell 2, driving the packaging film 17 to extend towards the packaging mold 6 and align with the packaging can 31 at the same time. Subsequently, the two cylinders 3 10 extend downward at the same time, driving the upper heat-sealing knife 11 and the lower heat-sealing knife 12 downward. Finally, the lower heat-sealing knife 12 presses the packaging film 17 tightly against the mouth of the packaging can 31 to package the packaging can 31 and cut the packaging film 17. After completion, the two cylinders 3 10 drive the upper heat-sealing knife 11 and the lower heat-sealing knife 12 to retract upward. Subsequently, the two cylinders 4 15 also retract. At the same time, the two motors 16 will rotate, winding up the waste film 18 with holes cut out and making the packaging film 17 roll out towards the waste film 18 to replace the packaging film 17 at the packaging position. Finally, the cylinder 1 drives the sealing plate 4 and the packaging table 5 to move towards the outside of the installation shell 2, and then the packaged finished product can be taken down manually. By packaging food in a sealed space, it avoids the problem that dust in the external environment falls on the food, resulting in dirt in the packaged food and making the food product not meet the hygiene standards, improving the safety of food.

[0044] As an implementation manner of the present invention, referring to Figure 7 , sterilization lamps 19 are fixedly installed on the inner walls of the left and right sides of the installation shell 2.

[0045] The sterilization lamp 19 is an ultraviolet sterilization lamp or other devices that can emit sterilization light. The sterilization lamp 19 sterilizes and disinfects the inside of the installation shell 2 by continuously emitting ultraviolet rays, preventing bacteria from growing inside the installation shell 2. At the same time, due to the blocking of the installation shell 2 and the sealing plate 4, it can reduce the harm of ultraviolet rays to the human body, solve the problem of bacteria growth inside the installation shell 2, and avoid harm to the human body as much as possible while improving food hygiene and safety.

[0046] As an implementation manner of the present invention, referring to Figure 3 ,Figure 9 , Figure 10 , a partition plate 8 is provided with an L-shaped material hole 20 in the middle of its interior, and a material pipe 9 is fixedly installed on the material hole 20 near one end of the sealing plate 4.

[0047] The bottom of the partition plate 8 is closely attached to the tabletop of the packaging table 5. The L-shaped material hole 20 communicates the side wall and the bottom surface of the partition plate 8. The material pipe 9 accesses from the hole in the side wall. When the partition plate 8 completely seals the packaging can 31, the liquid food is injected from the hole in the side wall through the material pipe 9, and then the liquid food is injected into the interior of the packaging can 31 from the bottom surface of the partition plate 8 through the material hole 20. By providing the material hole 20 inside the partition plate 8, the partition plate 8 can completely seal the can mouth of the packaging can 31 for feeding, further reducing the contact between the liquid food and the air.

[0048] As an embodiment of the present invention, referring to Figure 3 , Figure 9 , an L-shaped nitrogen gas hole 21 is provided inside the partition plate 8 in parallel with the material hole 20. An air inlet pipe 22 is fixedly installed on the nitrogen gas hole 21, and the air inlet pipe 22 passes through the sealing plate 4.

[0049] The arrangement of the nitrogen gas hole 21 is the same as that of the material hole 20. The nitrogen gas hole 21 is parallel to the material hole 20. The air inlet pipe 22 is also connected to the side surface of the partition plate 8 and is parallel to the material pipe 9. One end of the air inlet pipe 22 away from the nitrogen gas hole 21 is connected to a nitrogen gas source. After the partition plate 8 seals the can mouth of the packaging can 31, nitrogen gas is first injected into the interior of the packaging can 31 through the nitrogen gas hole 21, then food is injected through the material pipe 9, and finally it is packaged; the injection of nitrogen gas makes the shelf life of the packaged food longer, reducing food waste caused by too short a shelf life of the food.

[0050] As an embodiment of the present invention, referring to Figure 3 , Figure 9 , an L-shaped air extraction hole 23 is provided inside the partition plate 8 in parallel with the material hole 20. An air outlet pipe 24 is fixedly installed on the air extraction hole 23, and the air outlet pipe 24 passes through the sealing plate 4.

[0051] The air extraction hole 23 is symmetric with the material hole 20 and the nitrogen gas hole 21. One end of the air outlet pipe 24 far from the air extraction hole 23 is connected to an air suction device, which can be an air pump or other devices capable of effectively sucking air. After the partition plate 8 completely seals the mouth of the packaging can 31, the air suction device will extract about 80% of the air inside the packaging can 31 through the air outlet pipe 24 and the air extraction hole 23 and then stop air extraction. Subsequently, nitrogen gas is injected into the can through the nitrogen gas hole 21, food is injected into the can through the material hole 20, and finally, after the partition plate 8 is removed, the packaging can 31 is sealed. By extracting most of the air inside the packaging can 31 in advance, injecting nitrogen gas, and finally injecting food for sealing, the oxygen inside the packaging can 31 is further reduced, the growth of bacteria is reduced, the shelf life and hygienic safety of the food are improved, and at the same time, food waste caused by the too short shelf life of the food is reduced.

[0052] As an implementation mode of the present invention, referring to Figure 6 , a square notch 25 matching with the encapsulation mold 6 is opened on the encapsulation table 5, and the encapsulation mold 6 is horizontally placed in the square notch 25.

[0053] By using the mutual cooperation of the square notch 25 and the encapsulation mold 6, the encapsulation mold 6 can be horizontally placed in the square notch 25 on the encapsulation table 5 to complete the installation. At the same time, if the encapsulation mold 6 needs to be replaced, it can also be quickly removed, making the installation and maintenance of the encapsulation mold 6 more convenient without disassembling the encapsulation table 5.

[0054] As an implementation mode of the present invention, referring to Figure 1 、 Figure 3 、 Figure 5 , an electric slide rail 26 is horizontally and fixedly installed on the installation shell 2, a slider 27 is slidably installed on the electric slide rail 26, a material pushing device 28 is fixedly installed on the slider 27, and a cylinder five 29 is vertically installed in the square notch 25. A push plate 30 is fixedly installed on the output end of the cylinder five 29.

[0055] After the encapsulation is completed, when the cylinder one 3 drives the sealing plate 4 and the encapsulation table 5 to leave the installation shell 2, the electric slide rail 26 drives the slider 27 to move from one end of the electric slide rail 26 to the other end. At the same time, the cylinder five 29 inside the square notch 25 extends, and the push plate 30 pushes the encapsulated packaging can 31 to extend out of the encapsulation mold 6. The material pushing device 28 installed on the slider 27 pushes the encapsulated packaging can 31 off the encapsulation table 5 to complete the unloading. By driving the slider 27 by the electric slide rail 26 and then driving the material pushing device 28 to reciprocate left and right and cooperating with the cylinder five 29, automatic unloading is realized, and the production efficiency is improved.

[0056] As an implementation mode of the present invention, referring to Figure 3 、 Figure 6 、 Figure 11, the pushing device 28 is a square pipeline, and the inner pipe of the square pipeline is the same size as the packaging can 31. Two torsion springs 32 are installed at the lower part inside the square pipeline, and two suction ports 33 are provided on the push plate 30.

[0057] The packaging can 31 is installed inside the pipeline of the pushing device 28. The packaging cans 31 are vertically stacked inside the pushing device 28. However, when stacking, they can only fall naturally and cannot be artificially squeezed to prevent the packaging cans 31 from getting stuck together and unable to be separated. The two torsion springs 32 hold the packaging cans 31 inside the pushing device 28 to prevent them from falling. When the packaging platform 5 is moved out of the installation housing 2 and the packaging die 6 is aligned with the pushing device 28, the packaging platform 5 stops. The pushing device 28 moves from one end of the electric slide rail 26 to the other end. At the same time, the cylinder five 29 extends to push out the packaged packaging can 31. When the pushing device 28 moves to the packaging die 6, it pushes the packaged packaging can 31 away in the moving direction. When the pushing device 28 is facing the packaging die 6, the pushing device 28 pauses briefly. The two suction ports 33 on the push plate 30 are both connected to an external suction device. Subsequently, the two suction ports 33 on the push plate 30 suck the unpackaged and unencapsulated packaging cans 31 inside the pushing device 28. Then the cylinder five 29 retracts and pulls the unpackaged and unencapsulated packaging cans 31 into the packaging die 6. The new packaging can 31 above will move down by the position of one packaging can 31. At the same time, due to the action of the torsion spring 32, the lowermost packaging can 31 is stuck at the torsion spring 32, achieving the purpose of taking only one packaging can 31 at a time. Subsequently, the electric slide rail 26 continues to move in the original moving direction, and the pushing device 28 pushes the packaged packaging can 31 off the packaging platform 5, realizing automatic unloading and automatic replacement of the packaging can 31. Moreover, the unloading and the replacement of the packaging can 31 are linked and occur almost simultaneously, improving the production efficiency. The structure is also relatively compact and does not occupy too much space.

[0058] As an implementation mode of the present invention, referring to Figure 8 , two support rods 34 are vertically slidably installed on both the left and right sides of the upper heat-sealing knife 11. A pressing rod 35 is commonly fixed to the bottoms of the two support rods 34 on the left side, and a pressing rod 35 is also commonly fixed to the bottoms of the two support rods 34 on the right side. Sponge pressing rollers 36 are fixedly installed on both pressing rods 35. Spring two 37 is evenly wound around all four support rods 34. Spring two 37 is located between the pressing rod 35 and the upper heat-sealing knife 11.

[0059] When the partition plate 8 seals the mouth of the packaging can 31 and processes and fills the inside of the packaging can 31, the packaging film 17 will extend in advance and the height of the packaging film 17 is 1 mm higher than the upper surface of the partition plate 8. At this time, the two cylinders III 10 move the upper heat-sealing knife 11 and the lower heat-sealing knife 12 downward, so that the distance between the lower heat-sealing knife 12 and the packaging film 17 is 1 mm. Since the support rod 34 is longer than the distance from the lower heat-sealing knife 12 to the upper heat-sealing knife 11, the support rod 34 causes the sponge pressing roller 36 installed on the pressing rod 35 to press the packaging film 17 against the partition plate 8 and the packaging table 5. After the partition plate 8 finishes injecting the food and retracts, the two cylinders III 10 quickly press the lower heat-sealing knife 12, and the lower heat-sealing knife 12 drives the packaging film 17 to stick downward to the mouth of the packaging can 31. Finally, it is heated and sealed and edge-cut to realize the packaging of the food. Since the support rod 34 can slide on the upper heat-sealing knife 11 and there is a spring II 37 for buffering, it will not be damaged. By pressing the packaging film 17 against the partition plate 8 and the packaging table 5 in advance, it is quickly sealed after the food injection is completed, reducing the contact between the food and the air, further preventing the food from being contaminated by dirt or bacteria, while preventing the nitrogen from escaping and being wasted before packaging, and preventing the quality preservation effect from being reduced, and reducing the entry of external air into the inside of the packaging can 31, further improving the food hygiene and safety, and improving the shelf life, and reducing the waste caused by the food spoilage due to expiration.

[0060] As an implementation manner of the present invention, referring to Figure 1 , Figure 2 , Figure 3 , conveyor belts 38 are arranged on both the left and right sides of the installation housing 2, and two collection boxes 39 are fixedly installed on the working platform 1, and both of the two collection boxes 39 are located at the end of the conveying direction of the conveyor belt 38.

[0061] After the pushing device 28 pushes the packaged packaging can 31 off the packaging table 5, it will fall on the conveyor belt 38, and the conveyor belt 38 will convey it to the collection box 39 for collection, reducing the manual collection steps and improving the production efficiency.

[0062] Working principle: In the preparation stage, first turn on the sterilization lamp 19 to perform ultraviolet sterilization and disinfection on the inside of the installation shell 2. Then fix and install the packaging film 17 on the output shaft of one of the motors 16, and lead the packaging film 17 to the output shaft of the other motor 16 for fixation. Subsequently, place the packaging can 31 to fall naturally into the tube of the feeding device 28. The torsion spring 32 on the lower side inside the feeding device 28 will hold the packaging can 31, and make the bottom of the lowermost packaging can 31 coplanar with the bottom of the feeding device 28. Start the equipment. The first cylinder 3 extends to drive the sealing plate 4 and the encapsulation table 5 to move until the encapsulation mold 6 is aligned with the feeding device 28. Subsequently, the electric slide rail 26 drives the slider 27 and the feeding device 28 to move towards the encapsulation mold 6. When the feeding device 28 moves to be aligned with the encapsulation mold 6, the fifth cylinder 29 extends from the bottom of the square notch 25, and the push plate 30 is flush with the table surface of the encapsulation table 5. The suction port 33 on the push plate 30 sucks air to suck the bottom of the packaging can 31 out of the feeding device 28. Subsequently, the fifth cylinder 29 retracts towards the bottom of the square notch 25, pulls the packaging can 31 into the encapsulation mold 6, and then the suction port 33 stops sucking air. Since the torsion spring 32 will hold the packaging can 31 sliding down from above, only one packaging can 31 will be sucked in at a time. Subsequently, the feeding device 28 continues to move in the original movement direction until it completely leaves the encapsulation table 5 and then stops moving. Then the first cylinder 3 continues to push forward to send the encapsulation table 5 into the installation shell 2. When the encapsulation mold 6 is aligned with the lower heat-sealing knife 12, the sealing plate 4 also closes the box opening of the installation shell 2. Subsequently, the second cylinder 7 extends to drive the partition plate 8 to extend along the table surface of the encapsulation table 5 until it is aligned with the encapsulation mold 6 and completely covers the encapsulation mold 6. Then the two fourth cylinders 15 drive the two motors 16 to extend towards the installation shell 2 and drive the packaging film 17 to move towards the partition plate 8 inside the installation shell 2. Finally, the packaging film 17 moves to be aligned with the partition plate 8. At this time, the packaging film 17 is 1 mm higher than the top of the partition plate 8. Subsequently, the two third cylinders 10 extend downward to drive the upper heat-sealing knife 11 and the lower heat-sealing knife 12 to move downward until the lower heat-sealing knife 12 stops at a position about 1 mm above the packaging film 17. And because the four support rods 34 slidably mounted on the upper heat-sealing knife 11 are relatively long, the two pressing rods 35 fixedly mounted on the support rods 34 drive the two sponge pressing rollers 36 fixedly mounted on the pressing rods 35 to press the packaging film 17 on the left and right sides above the partition plate 8 onto the encapsulation table 5 under the action of the second spring 37. Subsequently, the air in the packaging can 31 is extracted through the air outlet pipe 24 and the air extraction holes 23 inside the partition plate 8 by an externally connected air extraction device. After extracting about 80% of the air inside the packaging can 31, the air extraction stops. Then nitrogen is injected into the packaging can 31 through the inlet pipe 22 and the nitrogen holes 21 inside the partition plate 8. Subsequently, the material pipe 9 injects liquid food into the packaging can 31 inside the encapsulation mold 6 through the material holes 20 inside the partition plate 8. After the injection is completed, the second cylinder 7 drives the partition plate 8 to retract.Subsequently, the two cylinders III 10 drive the upper heat-sealing knife 11 and the lower heat-sealing knife 12 to move downward to press the packaging film 17 onto the mouth of the packaging can 31 for heat-sealing, and cut the packaging film 17 around the mouth of the packaging can 31. After completion, the two cylinders III 10 drive the upper heat-sealing knife 11 and the lower heat-sealing knife 12 to retract upward. The two cylinders IV 15 also drive the two motors 16 to retract. At the same time, the two motors 16 rotate to wind up the waste film 18 with a cut gap and unwind the complete packaging film 17 to the horizontal for the next packaging. After the above steps are completed, the cylinder I 3 retracts, driving the sealing plate 4 and the packaging table 5 to be pulled out towards the outside of the installation housing 2. When the packaging die 6 is aligned with the feeding device 28, the cylinder I 3 stops. The electric slide rail 26 drives the slider 27 and the feeding device 28 to move towards the packaging die 6. At the same time, the cylinder V 29 extends to push the packaged packaging can 31 upward out of the packaging die 6. As the feeding device 28 moves, the packaged packaging can 31 will be pushed away from above the packaging die 6 in the moving direction of the electric slide rail 26. When the feeding device 28 moves to directly above the packaging die 6, the electric slide rail 26 stops briefly, and the suction port 33 sucks air to hold the bottom of the new packaging can 31. Subsequently, the cylinder V 29 retracts and pulls the new packaging can 31 into the packaging die 6 to achieve the replacement of the packaging can 31. After completion, the electric slide rail 26 continues to move in the original moving direction and pushes the packaged packaging can 31 away from the packaging table 5 and into the conveyor belts 38 on both sides of the installation housing 2. Finally, it is conveyed by the conveyor belts 38 to the collection box 39 for collection.
