Description
Technical Field
[0001] This application relates to the field of food packaging, and in particular to equipment for packaging quick-frozen dumplings. Background Technology
[0002] The frozen food industry has developed rapidly in recent years, and frozen dumplings, as an important category, are experiencing increasing market demand. With the expansion of production scale, improving the packaging efficiency and quality of frozen dumplings has become a key focus for the industry.
[0003] Currently, the packaging of premium-grade frozen dumplings requires workers to first stack the dumplings one by one into the individual compartments of a dumpling box. The filled boxes are then placed on a conveyor belt, which transports them to a film heat-sealing machine for sealing. To ensure a good sealing effect, the boxes need to be aligned before entering the heat-sealing machine. This process requires workers to check and adjust the position of each box individually to prevent skewing during sealing. However, manually aligning the boxes is labor-intensive, leading to worker fatigue and reduced efficiency. Furthermore, manual operation is susceptible to human error, making it difficult to ensure accurate alignment of every box and increasing the risk of skewing during sealing. This results in uneven patterns on the sealed boxes, affecting the overall appearance and quality of the product. Utility Model Content
[0004] In order to ensure that dumpling packaging boxes are accurately aligned before entering the film heat sealing machine, so that the pattern on the sealed dumpling packaging boxes is neat and not skewed, thereby improving the overall appearance quality of the product, this application provides quick-frozen dumpling packaging equipment.
[0005] The quick-frozen dumpling packaging equipment provided in this application adopts the following technical solution: A quick-frozen dumpling packaging equipment includes a frame, a first conveyor belt mounted on the frame, two second conveyor belts symmetrically positioned at the ends of the first conveyor belt, and two packaging conveyor belts respectively positioned at the ends of the second conveyor belts. The two dispensing conveyor belts are spaced apart, and a transfer conveyor belt is provided between the two dispensing conveyor belts. The transfer conveyor belt is equipped with a film heat sealing machine for sealing dumpling packaging boxes and a correction and arrangement mechanism for arranging and automatically correcting the deviation of dumpling packaging boxes.
[0006] By adopting the above technical solution, workers place the frozen dumplings one by one from the dispensing conveyor belt into the compartments inside the dumpling packaging boxes. The dumpling boxes are then placed on a transfer conveyor belt, where a correction mechanism automatically aligns and corrects the boxes. Afterward, the boxes are transported to a film heat-sealing machine for sealing. If a dumpling box is skewed, the correction mechanism on the transfer conveyor belt will guide and correct it during operation, ensuring it neatly positions itself between the correction guide plates. This avoids the tedious manual inspection and adjustment of each box, reducing worker workload and minimizing the impact of random human error. It ensures each box is accurately aligned, resulting in neat patterns on the sealed packaging and improving the overall appearance and quality of the product.
[0007] Optionally, the correction and arrangement mechanism includes two support seats fixed at intervals to the frame and a correction guide plate disposed between the two support seats. The end of the correction guide plate away from the film heat sealer is provided with an arc-shaped guide corner, and the ends of the two correction guide plates close to the film heat sealer are provided with arrangement gates that can move closer to or further away from each other.
[0008] By adopting the above technical solution, when dumpling packaging boxes are conveyed on the transfer conveyor belt, the arc-shaped guide corner of the correction guide plate at the end away from the film heat sealer guides and corrects the dumpling packaging boxes, ensuring they neatly enter between the two correction guide plates. After the dumpling packaging boxes enter between the two correction guide plates, the arrangement barrier at the end near the film heat sealer temporarily blocks the dumpling packaging boxes, allowing the dumpling packaging boxes on the transfer conveyor belt to be neatly arranged to a certain number. Then, the arrangement barrier opens, allowing the arranged dumpling packaging boxes to enter the film heat sealer for sealing. The arrangement barrier setting can control the number and rhythm of dumpling packaging boxes entering the film heat sealer, achieving neat arrangement and orderly sealing of dumpling packaging boxes, improving packaging efficiency and quality.
[0009] Optionally, a support frame is fixed between the two support seats, a lifting screw is threaded onto the support frame, a pressure plate is rotatably connected below the lifting screw, a guide rod is fixed to the top of the pressure plate, and the guide rod is slidably connected to the support frame.
[0010] By adopting the above technical solution, during the packaging process of quick-frozen dumplings, when the dumpling packaging boxes move on the transfer conveyor belt to the front of the arrangement gate for neat arrangement, the pressure plate will limit the top of the dumpling packaging boxes, preventing multiple dumpling packaging boxes from overlapping and intersecting at the edges due to the pushing force applied by the transfer conveyor belt. This ensures the normal sealing operation of the subsequent film heat sealing machine. In addition, the height of the pressure plate is adjustable to adapt to dumpling packaging boxes of different heights and sizes.
[0011] Optionally, the support base is threaded with an adjusting screw in the horizontal direction. One end of the adjusting screw is rotatably connected to the correction guide plate. A guide rod is fixed on the side of the correction guide plate near the support base, and the guide rod is slidably connected to the support base.
[0012] By adopting the above technical solution, the distance between the two correction guide plates can be adjusted by adjusting the screw, thereby adapting to dumpling packaging boxes of different widths and sizes, so that the correction arrangement mechanism can arrange and automatically correct dumpling packaging boxes of different specifications.
[0013] Optionally, an opening and closing cylinder is fixed on the support base, and the output end of the opening and closing cylinder is fixedly connected to the arrangement of the baffle gate.
[0014] By adopting the above technical solution, the opening and closing of the arrangement gate is controlled by a simple and sensitive opening and closing cylinder, which can quickly respond to control signals and promptly open or close the arrangement gate, thereby improving the separation efficiency of dumpling packaging boxes.
[0015] Optionally, the two arranged gates are provided with guide ramps on the side that is close to each other.
[0016] By adopting the above technical solution, when a set of arranged dumpling packaging boxes enters the film heat sealing machine, the arrangement gates will approach and close each other under the drive of the opening and closing cylinder. At this time, the guide slope will separate the first dumpling packaging box of the next set from the last dumpling packaging box of the previous set. The guide slope facilitates the arrangement gates to cut between the two dumpling packaging boxes.
[0017] Optionally, multiple guide rollers are rotatably connected to the front of the arc-shaped guide corner of the correction guide plate.
[0018] By adopting the above technical solution, multiple guide rollers can further assist dumpling packaging boxes to enter the space between two correction guide plates more smoothly, thereby improving the correction and guidance effect.
[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. If the dumpling packaging box is tilted, the correction and arrangement mechanism on the transfer conveyor belt will play a role during operation, guiding and correcting the tilted dumpling packaging box so that it neatly enters between the correction guide plates. This avoids the tedious operation of manually checking and adjusting the position of each dumpling packaging box, thereby reducing the labor intensity of the staff and reducing the impact of random factors in human operation. This ensures that each dumpling packaging box is accurately positioned, guarantees that the pattern on the sealed dumpling packaging box is neat, and improves the overall appearance and quality of the product. 2. The arrangement of the baffle gates can control the number and rhythm of dumpling packaging boxes entering the film heat sealing machine, achieving neat arrangement and orderly sealing of dumpling packaging boxes, and improving packaging efficiency and quality; 3. During the packaging process of quick-frozen dumplings, when the dumpling boxes move on the conveyor belt to the front of the arrangement gate for neat arrangement, the pressure plate will limit the top of the dumpling boxes to prevent multiple dumpling boxes from overlapping and intersecting at the edges due to the pushing force applied by the conveyor belt. This ensures the normal sealing operation of the subsequent film heat sealing machine. In addition, the height of the pressure plate is adjustable to accommodate dumpling boxes of different heights and sizes. Attached Figure Description

[0022] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.
[0023] This application discloses a quick-frozen dumpling packaging device. (Refer to...) Figure 1 and Figure 2 The quick-frozen dumpling packaging equipment includes a frame 1, a first conveyor belt 2 mounted on the frame 1, two second conveyor belts 3 symmetrically positioned at the ends of the first conveyor belts 2 and perpendicular to their conveying direction, two packaging conveyor belts 4 respectively positioned at the ends of the second conveyor belts 3 and perpendicular to their conveying direction, a film heat-sealing machine 5 for sealing the dumpling packaging boxes, and a web-aligning mechanism 6. The two packaging conveyor belts 4 are spaced apart, and a transfer conveyor belt 7 connects them. The film heat-sealing machine 5 and the web-aligning mechanism 6 are mounted on the transfer conveyor belt 7. The film heat-sealing machine 5 uses heat sealing technology to seal the film to the dumpling packaging boxes through heating. The web-aligning mechanism 6 is used to arrange and automatically correct the web alignment of the dumpling packaging boxes.
[0024] Frozen dumplings are conveyed from the first conveyor belt 2 to two second conveyor belts 3 at the end. From there, they are conveyed to the two side packaging conveyor belts 4. Workers place the frozen dumplings from the packaging conveyor belts 4 into the compartments of dumpling packaging boxes. The boxes are then placed on the transfer conveyor belt 7, where a correction mechanism 6 automatically aligns and corrects the dumpling boxes. Afterward, the boxes are conveyed to the film heat-sealing machine 5 for sealing. If a dumpling box is tilted, the correction mechanism 6 on the transfer conveyor belt 7 will guide and correct it during operation, ensuring it fits neatly between the correction guide plates 62. This avoids the tedious manual inspection and adjustment of each dumpling box's position.
[0025] Specifically, refer to Figure 2 and Figure 3 The alignment and arrangement mechanism 6 includes two support seats 61 fixed at intervals on the frame 1, an alignment guide plate 62 disposed between the two support seats 61, an arrangement gate 63 disposed on the end of the alignment guide plate 62 near the film heat sealer 5, a support frame 64 fixed between the two support seats 61, a lifting screw 641 threadedly connected to the support frame 64, a pressure plate 642 rotatably connected below the lifting screw 641, a guide rod 643 fixed to the top of the pressure plate 642 and slidably connected to the support frame 64, an adjusting screw 621 threadedly connected to the support seat 61 in the horizontal direction and rotatably connected to the alignment guide plate 62, a guide rod 622 fixed to the side of the alignment guide plate 62 near the support seat 61 and slidably connected to the support seat 61, and an opening and closing cylinder 631 fixed to the support seat 61 and whose output end is fixedly connected to the arrangement gate 63.
[0026] Among them, reference Figure 2 and Figure 3 The end of the guide plate 62 furthest from the film heat sealer 5 is provided with an arc-shaped guide bend 623. This arc-shaped guide bend 623 is used to guide and correct the dumpling packaging boxes, allowing them to neatly enter between the two guide plates 62. Multiple guide rollers 624, made of rubber, are rotatably connected to the front of the arc-shaped guide bend 623 of the guide plate 62. These multiple guide rollers further assist the dumpling packaging boxes in entering smoothly between the two guide plates 62, improving the guiding and correcting effect. A baffle 63 is used to temporarily block the dumpling packaging boxes entering between the two guide plates 62, ensuring that the dumpling packaging boxes on the conveyor belt 7 are neatly arranged to a certain number before entering the film heat sealer 5 for sealing. The two arrangement gates 63 are provided with a guide slope 632 on the side that is close to each other. The guide slope 632 facilitates the timely separation of the first dumpling packaging box of the next group from the last dumpling packaging box of the previous group after the arrangement gates 63 are closed and after a group of arranged dumpling packaging boxes enter the film heat sealing machine 5.
[0027] As the dumpling boxes are conveyed on the transfer conveyor belt 7, the arc-shaped guide corner 623 at the end of the correction guide plate 62 away from the film heat sealer 5 guides and corrects the dumpling boxes, ensuring they neatly enter between the two correction guide plates 62. After the dumpling boxes enter between the two correction guide plates 62, the arrangement barrier 63 at the end near the film heat sealer 5 temporarily blocks the dumpling boxes, allowing them to be neatly arranged on the transfer conveyor belt 7 to reach a certain number. Then, the arrangement barrier 63 opens, allowing the arranged dumpling boxes to enter the film heat sealer 5 for sealing.
[0028] When the lifting screw 641 is rotated, it is threadedly connected to the support frame 64, and the guide rod 643 on the top of the pressure plate 642 is slidably connected to the support frame 64, allowing the pressure plate 642 to rise and fall under the drive of the lifting screw 641. The pressure plate 642 is used to limit the top of the dumpling packaging box, preventing the edges of adjacent dumpling packaging boxes from overlapping and intersecting due to the pushing force applied by the conveyor belt when multiple dumpling packaging boxes are moved to the front of the arranging plate for neat arrangement, thus affecting the normal sealing operation of the subsequent film heat sealing machine 5. Moreover, by rotating the lifting screw 641, the height of the pressure plate 642 can be adjusted to accommodate dumpling packaging boxes of different heights. When the adjusting screw 621 rotates, it is threadedly connected to the support base 61, and the guide rod 622 is slidably connected to the support base 61, so that the correction guide plate 62 can move horizontally under the drive of the adjusting screw 621, thereby adjusting the distance between the two correction guide plates 62 to adapt to dumpling packaging boxes of different widths.
[0029] The implementation principle of a quick-frozen dumpling packaging device according to an embodiment of this application is as follows: Quick-frozen dumpling packaging boxes are conveyed to a second conveyor belt 3 via a first conveyor belt 2, and then guided by the second conveyor belt 3 to two packaging conveyor belts 4. Workers place the quick-frozen dumplings one by one into the compartments inside the dumpling packaging boxes on the packaging conveyor belts 4. The dumpling packaging boxes are then placed on a transfer conveyor belt 7. On the transfer conveyor belt 7, the dumpling packaging boxes are first guided and corrected by the arc-shaped guide corner 623 and guide roller 624 of the correction guide plate 62, and then enter between the two correction guide plates 62. A placement barrier 63 temporarily blocks the dumpling packaging boxes to ensure they are neatly arranged. A pressure plate 642 limits the top of the dumpling packaging boxes to prevent their edges from intersecting. When a certain number of dumpling packaging boxes have been arranged, an opening / closing cylinder 631 controls the placement barrier 63 to open, allowing the dumpling packaging boxes to enter the film heat-sealing machine 5 for sealing and packaging. This quick-frozen dumpling packaging equipment automatically corrects and arranges the dumpling boxes, avoiding the labor-intensive, inefficient, and misaligned sealing problems associated with manual box alignment. It ensures each box is accurately aligned, guaranteeing neat and uniform packaging patterns and improving the overall appearance and quality of the product. Furthermore, it is adaptable to different sizes of dumpling boxes, enhancing the equipment's versatility and applicability.
[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
