[0002] With the continuous development of technology and the accelerating pace of life, unmanned smart restaurants are gradually entering the public eye. These restaurants integrate big data, artificial intelligence, and automation technologies to create efficient, transparent, and healthy catering solutions, providing consumers with convenient and nutritionally balanced dining services and meeting modern people's demand for healthy eating.

[0003] Unmanned smart restaurants utilize automated cooking machines for stir-frying, achieving automation in the cooking process. However, the actual ingredient loading still requires manual intervention. To address this, various ingredient bags are sequentially ordered and connected in the cooking sequence, with each bag opened and added to the pan as the cooking progresses, automating the ingredient loading process. To this end, the applicant's R&D team designed an ingredient bag connection device to connect multiple ingredient bags sequentially, improving the efficiency and standardizing the connection process. However, after vacuum packaging, the ingredient bags vary in thickness and length due to differences in ingredient quantity and characteristics. The varying lengths of the bags make it difficult to connect them using the connection device, hindering standardization of the connection process.

[0004] Therefore, a food bag sealing and cutting device was developed and designed to seal the edges of each food bag and cut it to a set length to meet the requirements of the subsequent food bag stringing device for connecting and processing bags. Utility Model Content

[0028] Example 1 like Figures 1 to 6 As shown, the food bag sealing and cutting device in this embodiment includes a support 1, a first pressing conveyor belt group 2, a second pressing conveyor belt group 3, a third pressing conveyor belt group 4, a sealing mechanism 5, and a cutting mechanism 6.

[0029] A bag-placement component 11 is provided at the front end of the support frame 1, on which food bags are placed. A transition guide component 12 is provided at the rear end of the support frame 1, through which the sealed and cut food bags fall into the next production node (food bag serial connection device). A support plate 13 is provided at the middle position along the left-right direction on the support frame 1, extending along the length of the support frame 1, and is used to support the food bags. During the movement of the food bags with the pressing conveyor belt group, the food bags are supported by the support plate 13.

[0030] The first pressing conveyor belt group 2 is located on the left side of the support 1 and extends along the length of the support 1. The first pressing conveyor belt group 2 is used to clamp one side of the food bag.

[0031] The second pressing conveyor belt group 3 is located on the right side of the support 1, and the second pressing conveyor belt group 3 extends along the length of the support 1. The second pressing conveyor belt group 3 is used to clamp the other side of the food bag.

[0032] The third pressing conveyor belt group 4 is mounted on the support 1, located between the first pressing conveyor belt group 2 and the second pressing conveyor belt group 3, and extends along the length of the support 1. The third pressing conveyor belt group 4 is used to clamp the middle position of the food bag. One end of the third pressing conveyor belt group 4 is located at the rear end of the support 1, and the other end is located at the middle position of the support 1.

[0033] The first pressing conveyor belt group 2, the second pressing conveyor belt group 3, and the third pressing conveyor belt group 4 each include an upper pressing conveyor belt 71 and a lower pressing conveyor belt 72. The lower surface of the upper pressing conveyor belt 71 is located above the upper surface of the lower pressing conveyor belt 72, and there is space between the lower surface of the upper pressing conveyor belt 71 and the upper surface of the lower pressing conveyor belt 72 to allow the food bag to pass through.

[0034] The first pressing conveyor belt group 2, the second pressing conveyor belt group 3, and the third pressing conveyor belt group 4 all include a pressing conveyor belt drive mechanism, an upper drive pulley 74, an upper driven pulley 75, a lower drive pulley 76, and a lower driven pulley 77.

[0035] The upper drive pulley 74 and the upper driven pulley 75 are rotatably connected to both ends of the support 1 along its length, and the upper pressing conveyor belt 71 is connected between the upper drive pulley 74 and the upper driven pulley 75. The lower drive pulley 76 and the lower driven pulley 77 are rotatably connected to both ends of the support 1 along its length, and the lower pressing conveyor belt 72 is connected between the lower drive pulley 76 and the lower driven pulley 77.

[0036] The pressing conveyor belt drive mechanism drives the lower drive pulley 76 and the upper drive pulley 74 to rotate. Specifically, the pressing conveyor belt drive mechanism includes a first motor 731, a first drive shaft 732, a gearbox 733, and a second drive shaft 734. The output shaft of the first motor 731 is connected to the first drive shaft 732, the lower drive pulley 76 is mounted on the first drive shaft 732, the first drive shaft 732 is connected to the input end of the gearbox 733, the output end of the gearbox 733 is connected to the second drive shaft 734, and the upper drive pulley 74 is mounted on the second drive shaft 734.

[0037] The transmission 733 includes a transmission housing 7331 and a plurality of gears 7332 rotatably connected to the transmission housing 7331. Adjacent gears 7332 mesh with each other. The input end of the transmission 733 is connected to the first gear 7332, and the output end of the transmission 733 is connected to the last gear 7332. The input and output ends of the transmission 733 are respectively connected to the first drive shaft 732 and the second drive shaft 734, so that the first drive shaft 732 and the second drive shaft 734 have the same direction of rotation and speed, thereby realizing the synchronous operation of the upper pressing conveyor belt 71 and the lower pressing conveyor belt 72, realizing the clamping of the food bag and driving the food bag to move.

[0038] The rotation of the output shaft of the first motor 731 drives the first transmission shaft 732 to rotate, which in turn drives the lower drive pulley 76 to rotate. The lower drive pulley 76 drives the lower pressing conveyor belt 72 to run and also drives the lower driven pulley 77 to rotate. The first transmission shaft 732 drives the second transmission shaft 734 to rotate via the gearbox 733, which in turn drives the upper drive pulley 74 to rotate. The upper drive pulley 74 drives the upper pressing conveyor belt 71 to run and also drives the upper driven pulley 75 to rotate.

[0039] The food bag sealing and cutting device of this embodiment adopts a single motor (first motor 731) in conjunction with a gearbox 733 and a drive shaft (first drive shaft 732, second drive shaft 734). It has a compact structure and simple control. It synchronously drives the upper and lower pressing conveyor belts, ensuring the uniformity of the clamping force of the upper and lower pressing conveyor belts and synchronizing the conveying speed of the lower surface of the upper pressing conveyor belt and the upper surface of the lower pressing conveyor belt.

[0040] The sealing mechanism 5 is located at the front end of the support 1 and is situated between the first pressing conveyor belt group 2 and the second pressing conveyor belt group 3. The sealing mechanism 5 is used to seal one side of the food bag.

[0041] The sealing mechanism 5 includes a first support frame 51, an upper clamping plate 52, a lower clamping plate 53, and a push-drive mechanism 54. The first support frame 51 is mounted on a bracket 1, the upper clamping plate 52 is mounted on the first support frame 51, and the lower clamping plate 53 is mounted on either the first support frame 51 or the bracket 1. The push-drive mechanism 54 moves the upper clamping plate 52 closer to or further away from the lower clamping plate 53. When the upper clamping plate 52 moves away from the lower clamping plate 53, a space is left between the upper clamping plate 52 and the lower clamping plate 53 to allow the food bag to pass through; when the upper clamping plate 52 moves closer to the lower clamping plate 53, the upper clamping plate 52 and the lower clamping plate 53 together clamp the food bag. The upper clamping plate 52 and / or the lower clamping plate 53 are used to heat the food bag. In this embodiment, a heating unit (such as a heating wire) is arranged on the lower end face of the lower clamping plate 53. Powering the heating unit causes radiation, raising the temperature of the lower clamping plate 53, thereby heating the food bag. During the process of the upper clamping plate 52 and the lower clamping plate 53 jointly holding the food bag, the food bag is heated and sealed.

[0042] The edge-sealing mechanism 5 also includes a guide seat 55 and a guide shaft 56. The guide seat 55 is mounted on the first support frame 51, and the guide shaft 56 is mounted on the upper clamping plate 52. The guide shaft 56 is arranged vertically and slides in conjunction with the guide seat 55. When the push driver 54 moves the upper clamping plate 52 closer to or further away from the lower clamping plate 53, the sliding contact between the guide seat 55 and the guide shaft 56 guides and limits the movement.

[0043] The push-drive 54 is configured as a cylinder, with the cylinder body end mounted on the first support frame 51 and the telescopic end of the cylinder connected to the upper clamping plate 52. The telescopic end of the cylinder extends or retracts relative to the cylinder body end, causing the upper clamping plate 52 to move closer to or further away from the lower clamping plate 53.

[0044] The edge sealing mechanism 5 in this embodiment adopts a cylinder-driven upper and lower clamping plate structure, which, together with the guide shaft 56 and the guide seat 55, ensures the smoothness of the clamping action and the accuracy of the alignment. The heated clamping plate can quickly and reliably complete the edge sealing operation.

[0045] A cooling fan 57 is installed on the bracket 1. The cooling fan 57 is located at the rear end of the sealing mechanism 5 and is used to blow airflow onto the food bag. In this way, the sealed edge of the food bag can be cooled in time after heat sealing, effectively preventing the sealed edge from sticking and being damaged due to residual heat, thus ensuring the sealing quality and yield.

[0046] The cutting mechanism 6 is located at the rear end of the support 1 and is situated between the first pressing conveyor belt group 2 and the third pressing conveyor belt group 4. The cutting mechanism 6 is used to cut the outer side of the sealing edge of the food bag.

[0047] The cutting mechanism 6 includes a second support frame 61, a second motor 62, and a cutting blade 63. The second support frame 61 is mounted on the bracket 1, and the second motor 62 is mounted on the second support frame 61. The output shaft of the second motor 62 is connected to the cutting blade 63, which is used to cut the outer side of the sealed edge of the food bag. When the output shaft of the second motor 62 rotates, it drives the cutting blade 63 to rotate, and the rotating cutting blade 63 cuts the outer side of the sealed edge of the food bag.

[0048] The food bag sealing and cutting device in this embodiment operates as follows: A food bag is placed on the bag-laying component 11. One side of the food bag is held by the first pressing conveyor belt group 2, and the other side is held by the second pressing conveyor belt group 3. The first and second pressing conveyor belt groups hold both sides of the food bag and move the food bag, cooperating with the sealing mechanism 5 to perform a precise sealing operation on the food bag. After the food bag enters the space between the upper clamping plate 52 and the lower clamping plate 53, the upper clamping plate 52 moves closer to the lower clamping plate 53, and the lower clamping plate 53 heats the food bag to perform heat sealing (secondary sealing). The open side of the food bag has already been sealed once before passing through the sealing mechanism 5.

[0049] After the food bag is sealed twice, as the first and second pressing conveyor belts clamp the two sides of the food bag and move the food bag continuously, the cooling fan 57 blows airflow to the sealed edge of the food bag to cool it down.

[0050] The first and second pressing conveyor belts clamp the two sides of the food bag, while the third pressing conveyor belt 4 clamps the middle of the food bag, forming a stable three-point clamping conveyor. This, combined with the cutting mechanism 6, allows for precise cutting of the food bag. The output shaft of the second motor 62 rotates, driving the cutting blade 63 to rotate. The rotating cutting blade 63 cuts the outer edge of the food bag's sealed area.

[0051] After sealing and cutting, the food bags are guided by transition guide 12 to the next production node.

Based on the above description, those skilled in the art should have a clear understanding of the food bag sealing and cutting device and bag-connecting machine of this utility model. Of course, the above description is only a preferred embodiment of this utility model and does not limit the patent scope of this utility model.
