Description

Technical Field

[0001] The invention relates to the technical field of pre-prepared meal packaging equipment, and in particular to a pre-prepared meal production and packaging equipment. Background Art

[0002] Pre-prepared meals are the product of food industrialization. They are pre-packaged dishes made from one or more edible agricultural products and their products as raw materials, industrially pre-processed, and can only be eaten after heating or cooking.

[0003] During the processing of pre-prepared meals, the ingredients need to be selected and cleaned, processed, put into food packaging boxes, plastic-sealed on the surface of the packaging boxes, marked on the plastic-sealed surface, and packed. In the plastic-sealing process on the surface of the packaging boxes, vacuum packaging machines and modified atmosphere packaging machines are usually used. The modified atmosphere packaging machine uses packaging film to package the ingredients. The air in the packaging box is extracted and filled with inert gas to reduce oxidation of the ingredients and extend the shelf life.

[0004] For example, Chinese invention patent CN112093118B discloses a modified atmosphere packaging machine and a modified atmosphere packaging method, the packaging machine includes an upper film and a lower film for packaging articles and an upper cavity and a lower cavity placed therebetween, the lower cavity can be combined with or separated from the upper cavity, the upper and lower cavities are respectively provided with an upper concave inner cavity and a lower concave inner cavity, a heating plate is provided in the upper concave inner cavity for pressing the peripheral parts of the upper film and the lower film to realize the packaging of articles, when the lower cavity is combined with the upper cavity, a first space between the upper film and the upper concave inner cavity, a second space between the upper film and the lower film, and a third space between the lower film and the lower concave inner cavity are formed in the modified atmosphere packaging machine, the upper cavity is provided with a channel for extracting air in the first and second spaces and a channel for filling the first and second spaces with inert gas after the vacuum degree of the second space reaches the requirement, and the lower cavity is provided with a channel for filling the first and second spaces with inert gas after the vacuum degree of the second space reaches the requirement, and the lower cavity is provided with a channel for filling the first and second spaces with inert gas. The cavity is provided with a channel for extracting air from the third space and a channel for filling the third space with inert gas. The use of the packaging machine and method can reduce equipment cost and processing cost; however, the packaging machine still has the following problems: the pre-prepared dishes contain soup or diluted ingredients, such as pickled fish, preserved vegetable pork, and boiled beef, which are transported to the packaging box through a pipeline after pre-processing. Since the conveying port is 10-20 cm away from the packaging box and the pre-prepared ingredients are input in a quantitative manner, the soup and ingredient particles in the ingredients splash onto the upper edge of the packaging box. The operating personnel are required to inspect the upper edge of the packaging box one by one and clean the soup and ingredient particles splashed onto the upper edge, thereby increasing the processing cost. If the soup and ingredient particles are not cleaned, the packaging film cannot be tightly sealed with the packaging box, resulting in the problem of leakage of the pre-prepared dishes.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects:

[0018] 1. The present invention provides a pre-prepared meal production and packaging equipment. Before sealing the film, the packaging equipment uses a cleaning mechanism to suck away the soup and food particles on the upper edge of the packaging box by suction air pressure, and then performs modified atmosphere sealing and packaging, so that the packaging film and the packaging box are tightly sealed, the pre-prepared meal does not leak out, and the processing cost is reduced.

[0019] 2. The present invention provides a pre-prepared meal production and packaging equipment, and the cleaning mechanism is equipped with a plurality of electric telescopic cylinders on the front support rod. The two ends of the hole in the center of the electric telescopic cylinder are respectively connected to the hose and the bowl and plate. The vacuum equipment in the packaging line is connected to the hose, and the hose is connected to the bowl and plate. The bowl and plate are vertically pressed against the surface of the upper edge ring. The soup and food particles in the upper edge ring are quickly sucked away by the vacuum equipment, thereby improving production efficiency, realizing unmanned quality inspection, and reducing processing costs.

[0020] 3. The present invention provides a pre-prepared meal production and packaging equipment, in which the bowl and plate are divided into an outer bowl and an inner bowl and plate by a plurality of partitions, and a plurality of air passages are formed between the outer bowl and the inner bowl and plate to improve the air passage suction force and suction efficiency; a single air passage is prone to disperse the air pressure in the air passage, resulting in low suction efficiency and unclean suction, and multiple air passages are provided to improve the suction efficiency and suction cleanliness.

[0021] 4. The present invention provides a pre-prepared meal production and packaging equipment, in which the partition in the bowl is 1-3 cm lower than the edges of the outer bowl and the inner bowl, the outer bowl, the inner bowl and the partition together form a groove, and a number of freely rotating baffles are arranged on the groove. When the suction air pressure enters the airway, the baffles are arranged in a straight line due to the upward suction force of the airways on both sides. Since the two airways inject upward suction force at the same time, the baffles are affected by the suction force and are in a static and sequentially arranged state, so that the outer bowl, the inner bowl and the upper ring are relatively closed spaces, thereby improving the suction efficiency and cleanliness.

[0022] 5. The present invention provides a pre-prepared meal production and packaging equipment. When the bowls and plates drive the outer bowls and inner bowls to move downward, due to the existence of the blocking plates, part of the blocking plates occasionally adhere to food particles and soup. At this time, the airway is injected with suction force, and the blocking plates that adhere to the food particles are affected by the suction force. The blocking plates rotate by themselves to scrape the food particles into the airway and suck them away; some of the soup and food particles are adhered to the bottom end surface of the blocking plate body. At this time, multiple airways simultaneously suck, so that a single blocking plate is in a longitudinal static state or a free rotation and sequential arrangement state; specifically, the soup and food particles are adhered to the bottom end surface of the single blocking plate body. When the airway enters the suction force, the single blocking plate will have two forms. One form is that the blocking plate and the partition are perpendicular to each other up and down. This form is a gap caused by the adhesion of the soup and food particles. This form is that the single blocking plate is in a longitudinal static state; the other form is that multiple independent blocking plates are affected by the suction force of the airway, and the blocking plates rotate and are arranged in sequence in a straight row.

[0023] When a single baffle plate is in a longitudinal static state, the adjacent airways on the left and right complement each other to form a single independent closed state. Under the suction of the left and right airways, the baffle plates on both sides of the static baffle plate cannot be arranged and closed in sequence, and the baffle plate enters a free rotation or left-right swinging imbalance state; specifically, when a single baffle plate is in a longitudinal static state, that is, the first form, the baffle plate and the partition are perpendicular to each other up and down. This form is a gap caused by the adhesion of soup and food particles. Since the partitions are set to 8, 8 groups of airways are divided. When a single or multiple baffle plates on a certain partition adhere to food particles to cause gaps, the left and right airways adjacent to it complement each other to form a single large closed space. When suction force enters the airway, the baffle plate is acted upon by the suction force, and the baffle plate is in the joint action of free rotation and left-right swinging imbalance, which scrapes and sucks away the food particles and soup, reduces the residue of food particles and soup in the upper ring, and improves the cleaning efficiency.

[0024] 6. The present invention provides a pre-prepared meal production and packaging equipment, wherein the upper ring surface of the packaging box is adapted to abut against the edges of the outer bowl and the inner bowl, and the wall thickness of the outer bowl and the inner bowl is 0.1-0.5 cm, so that the outer bowl, the inner bowl and the upper ring surface form a relatively closed space; considering that there is a gap between the cavity and the packaging box, when the bowl moves down, it cannot completely abut against the upper ring surface, and thus the present application innovatively designs the upper ring surface, and the width of the upper ring surface is increased by 1 cm, so that the bowl can better adapt to the upper ring of the packaging box, thereby improving cleaning efficiency and processing efficiency.

[0041] like Figure 1-Figure 10As shown, a pre-prepared meal production and packaging equipment provided in this embodiment includes a packaging line 1, on which a film sealing machine 3 is arranged, and a film placing shaft 4 and a film collecting shaft 5 are respectively arranged on both sides of the film sealing machine 3, and a cleaning mechanism 6 is arranged on the outer side of the film placing shaft 4, and the edge of the bowl and plate 65 in the cleaning mechanism 6 is adapted to abut against the upper ring 91 of the packaging box 9, and the bowl and plate 65 absorbs the soup and food particles splashed from the upper ring 91 by air pressure; the cleaning mechanism 6 also includes a front support rod 61, on which a plurality of electric telescopic cylinders 64 are arranged, and a hole is arranged in the electric telescopic cylinder 64, and the hole is connected to the hose 63; the bottom of the electric telescopic cylinder 64 is adapted to fix the bowl and plate 65 through a threaded rod 654, and the bowl and plate 65 is connected through a plurality of partitions 10 divides the bowl 65 into an outer bowl 651 and an inner bowl 652, and the outer bowl 651 and the inner bowl 652 form an airway 653, and the airway 653 is connected to the hose 63 for air pressure circulation; a fixing plate 62 is arranged on the rear side of the film sealing machine 3 body, and the fixing plate 62 is fixedly connected to the front support rod 61, and the front support rod 61 is an inverted L shape; an operation panel 2 is arranged on the front side of the film sealing machine 3 body, and the operation panel 2 is connected to the power supply; in this embodiment, a cleaning mechanism 6 is arranged on one side of the film sealing machine 3 in the packaging line 1, and one end face of the front support rod 61 of the L-shaped body of the cleaning mechanism 6 is fixed to the side of the packaging line 1 close to the operation panel 2, and the other end face of the front support rod 61 is fixed on the fixing plate 62, and fixed The plate 62 is fixed to the rear side of the film sealing machine 3. At this point, the front support rod 61 is perpendicular to the lower mold body 7. Three cavities 8 are set on the lower mold body 7. The packaging box 9 is suitable for being placed in the cavity 8; three electric telescopic cylinders 64 are also vertically installed on the front support rod 61. The electric telescopic cylinder 64 is an existing product on the market and will not be described in detail here. A hole is set through the center of the electric telescopic cylinder 64. The top surface of the hole is sealed and connected to the hose 63. The hose 63 is connected to the suction pump. The suction pump is an existing product and will not be described in detail here. The bottom of the electric telescopic cylinder 64 is an internal thread adapted to the threaded rod 654. The threaded rod 654 is fixed to the top surface of the bowl of the outer bowl plate 651. The threaded rod 654 and the outer bowl plate 651 are also provided with a through hole 6 56. A plurality of partitions 10 are symmetrically arranged on the inner wall of the outer bowl 651. In the present embodiment, the number of the partitions 10 is 8. The partitions 10 are semi-crescent-shaped and are vertically sealed and fixed on the outer wall of the inner bowl 652. The inner bowl 652 is a solid bowl body. The inner bowl 652 and the outer bowl 651 form an airway 653 space. The airway 653 is connected to the hose 63 for air pressure circulation. The suction pump is connected to the hose, and the hose is connected to the bowl. The bowl is telescopically displaced up and down by an electric telescopic cylinder, so that the bowl is vertically pressed against the upper ring surface of the packaging box. The soup and food particles splashed in the upper ring are quickly sucked away by the suction pump, thereby improving production efficiency, realizing unmanned quality inspection, and reducing processing costs.

[0042] like Figure 3-Figure 10As shown, in this embodiment, a threaded rod 654 is set at the top center of the outer wall of the outer bowl plate 651, and the through hole 656 in the threaded rod 654 penetrates the body of the outer bowl plate 651; the body of the inner bowl plate 652 is a solid bowl body, and a plurality of partitions 10 are fixedly and sealedly set on the outer wall of the inner bowl plate 652, and the top of the partition 10 extends to the outer periphery of the through hole 656, and the other side of the partition 10 is vertically and sealedly fixed to the inner wall of the outer bowl plate 651, and a plurality of air passages 653 are formed between the outer bowl plate 651 and the inner bowl plate 652, and the distance between the outer bowl plate 651 and the inner bowl plate 652 is 1-3cm. A threaded rod 654 is vertically arranged at the center of the top of the outer bowl wall of the outer bowl plate 651, and a through hole 656 is arranged in the threaded rod 654. The through hole 656 runs through the body of the outer bowl plate 651, and the through hole 656 is used to connect the hose 63. Eight partitions 10 are vertically sealed and fixed on the inner wall of the body of the outer bowl plate 651. The partition 10 is a semi-crescent-shaped body, and its pointed corner extends upward to the outer periphery of the through hole 656, with the wide side of the crescent at the bottom. Eight airways 653 are formed between the outer bowl plate 651 and the inner bowl plate 652, and the airways are used to circulate the air pressure of the suction pump and the food particles and soup. A single airway can easily disperse the air pressure in the airway, resulting in an unsatisfactory suction effect and unclean suction. Arranging multiple airways can improve the efficiency and cleanliness of suction, increase the airway pressure value, and improve the suction efficiency.

[0043] like Figure 6-Figure 10As shown, in this embodiment, the end surfaces on both sides of the partition 10 are respectively abutted against the inner wall of the outer bowl 651 and the outer wall of the inner bowl 652 to form a groove 657. The recessed size of the groove 657 is 1-3 cm, and the edges of the outer bowl 651 and the inner bowl 652 are flush; a plurality of freely rotating blocking plates 11 are arranged in the groove 657, and the blocking plates 11 are used to close the air pressure in the airway 653. The outer bowl 651 is flush with the edge of the inner bowl 652, and is used to abut against the outer ring edge and the inner ring edge of the upper edge ring 91 in the packaging box 9. The end walls on both sides of the groove 657 body are perpendicular to the inner wall of the outer bowl 651 and the outer wall of the inner bowl 652. A blocking plate 11 is installed on the groove 657. The number of blocking plates 11 can be increased or decreased according to user needs. The blocking plate 11 is used to seal the air pressure in each airway 653; the baffle is 1-3 cm lower than the edge of the outer bowl and the inner bowl. When the outer bowl and the inner bowl move down, due to the existence of the baffle on the baffle, some food particles and soup occasionally adhere to the baffle or the bottom end surface of the baffle. At this time, suction force is injected into the airway, and the baffle with food particles adhered is affected by the suction force. The baffle rotates by itself to scrape the food particles into the airway and suck them away; there is also Part of the soup and food particles are adhered to the bottom end surface of the baffle plate. At this time, the left and right airways are sucked simultaneously, so that the single baffle plate is in a longitudinal static state or a free rotation and sequential arrangement state. The best state is that the baffle plate rotates itself to scrape the food particles into the airway and suck them away, and then freely rotates and arranges them in sequence; when a single baffle plate is in a longitudinal static state, at this time, due to the mutual suction effect of the left and right airways, the baffle plates on both sides of the static baffle plate itself cannot be arranged and closed in sequence, and enter a free rotation or left-right swinging imbalance state. At this time, the left and right airways complement each other to form a relatively large closed space. At this time, the food particles are affected by the suction force, free rotation and left-right swinging imbalance, so that the food particles and soup are scraped and rubbed off and then sucked away, thereby reducing the residue of food particles and soup in the upper ring and improving the cleaning efficiency.

[0044] like Figure 1-Figure 3 As shown, in this embodiment, the packaging line 1 is connected to several lower mold bodies 7 through a sprocket, and the lower mold bodies 7 are arranged in sequence and moved by the sprocket, and several cavities 8 are set on the main body of the lower mold body 7, preferably 3 cavities 8, and a packaging box 9 is suitable for placing in the cavity 8, and the lower surface of the upper edge ring 91 in the packaging box 9 is against the upper surface of the cavity 8, and the cavity 8 and the packaging box 9 are both round bowl-shaped bodies, and the width of the upper edge ring 91 in the packaging box 9 is 1-4cm; the upper edge ring surface of the packaging box is adapted to be against the edges of the outer bowl and the inner bowl, and the wall thickness of the outer bowl and the inner bowl is 0.1-0.5cm, so that the outer bowl, the inner bowl and the upper edge ring surface form a relatively closed space; considering that there is a gap between the cavity and the packaging box, when the bowl moves down, it cannot completely abut against the upper edge ring surface, and then the present application innovatively designs the upper edge ring surface, and the width of the upper edge ring surface is increased by 1cm, so that the bowl and the packaging box can better adapt to the upper edge ring of the packaging box, providing cleaning efficiency and processing efficiency.

[0045] The present invention provides a pre-prepared food production and packaging equipment, the working principle of which is as follows:

[0046] The lower mold body 7 in the packaging line 1 is transported and moved by the sprocket. When the lower mold body 7 moves to the right below the cleaning mechanism 6, the packaging line is in a paused state. The electric telescopic cylinder 64 in the front support rod 61 moves downward, and the bowl 65 is pressed against the packaging box 9 in the lower mold body 7. The packaging box 9 is placed in the cavity 8 in the lower mold body 7. The cavity 8 is adapted to the packaging box 9. At this time, the edges of the outer bowl 651 and the inner bowl 652 in the bowl 65 are pressed against the upper ring 9 on the body of the packaging box 9. 1, the width of the upper ring 91 is greater than the distance between the outer bowl 651 and the inner bowl 652, the width of the upper ring 91 is 1-4cm, the distance between the outer bowl 651 and the inner bowl 652 is 1-3cm, the width of the upper ring 91 is 1cm greater than the width of the bowl 651, and the width of the upper ring surface is increased by 1cm, so that the bowl can better fit the upper ring of the packaging box, improving cleaning efficiency and processing efficiency; the wall thickness of the outer bowl and the inner bowl is 0.1-0.5cm, so that the outer bowl plate, the inner bowl plate and the upper ring surface form a relatively closed space; at this time, the suction pump inputs suction air pressure to the hose 63, the hose 63 is connected to the top of the electric telescopic cylinder 64, and the air pressure reaches the airway 653 through the holes and perforations 657 in the inner cavity of the electric telescopic cylinder 64. The airway 653 is composed of the partition 10, the outer bowl plate 651 and the inner bowl plate 652. The top wall of the outer bowl plate 651 body is provided with a threaded rod 654, the threaded rod 654 is connected to the bottom of the electric telescopic cylinder 64, and the threaded rod 654 and the outer bowl plate 651 are penetrated by a perforation 656, and the inner bowl plate 652 is a solid bowl body, the size of the inner bowl plate 652 is smaller than the outer bowl plate 651, and the inner bowl plate 652 is a vertical sleeve The air passage 653 is formed by the partition 10, the outer bowl 651 and the inner bowl 652, and the air passage 653 is formed by the partition 10. The air passage 653 is formed by the partition 10, the outer bowl 651 and the inner bowl 652. The air passage 653 is formed by the partition 10, the outer bowl 651 and the inner bowl 652, and the air passage 653 is formed by the partition 10. The air passage 653 is formed by the partition 10, the outer bowl 651 and the inner bowl 652, and the air passage 653 is formed by the partition 10. The air passage 653 is formed by the partition 10, the outer bowl 651 and the inner bowl 652, and the air passage 653 is formed by the partition 10. The air passage 653 is formed by the partition 10, the outer bowl 651 and the inner bowl 652, and the air passage 653 is formed by the partition 10. The air passage 653 is formed by the partition 10, the outer bowl 651 and the inner bowl 652, and the air passage 653 is formed by the partition 10. The number of blocking plates 11 can be increased or decreased according to user needs. The blocking plates 11 are used to close the airflow in each airway 653 to prevent the airflow from overflowing. When the bowls and plates move down, the outer bowls and inner bowls in the bowls and plates are pressed against the upper ring of the packaging box. Due to the existence of the blocking plates, some of the blocking plates occasionally stick to food particles and soup. At this time, the airway is injected with suction air pressure, and the blocking plates that stick to the food particles are affected by the suction force. The blocking plates rotate themselves to scrape the food particles into the airway and suck them away; some soup and food particles are stuck to the bottom end surface of the blocking plate. At this time, the left and right airways are sucked at the same time, so that a single blocking plate is in a longitudinal static state or a free rotation state arranged in sequence; when a single blocking plate is in a longitudinal In the static state, the baffles on both sides of the static baffle plate cannot be arranged in sequence due to the suction effect of the left and right airways. Affected by the food particles, the baffles on both sides enter a state of free rotation or left-right swinging imbalance. At this time, the left and right airways complement each other to form a single relatively closed large space. The food particles are affected by the upward suction force, free rotation and left-right swinging imbalance, and the food particles and soup are scraped away and sucked out; other baffles without adhesion of soup and food particles are affected by the upward suction force generated by the left and right airways. The baffles rotate freely and are arranged in sequence to form a relatively closed single airway, thereby improving the cleaning efficiency and reducing the residue of food particles and soup in the upper ring.
