DETAILED DESCRIPTION

[0026] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Reference Figures 1-6 As shown, the utility model provides: an automatic filling and sealing mechanism for bowl porridge, comprising a conveyor 1 and a sealing assembly 6 installed on the conveyor 1, the conveyor 1 conveys the bowl body 3 to the bottom of the sealing assembly 6 for sealing, a plurality of limit devices 2 are fixed on the conveyor 1 through a conveyor belt, a support member 21 for supporting the bowl body 3 is installed on the limit device 2, the support member 21 extends upward for a distance, and a plurality of annular grooves 22 are provided on the limit device 2, the sealing assembly 6 includes a lifting mechanism, the lifting mechanism includes a heating ring 67 and a cutter 671 corresponding to the bowl body 3, the heating ring 67 is energized and heated to seal the heat-sealing film placed on the bowl body 3 on the bowl body 3, the cutter 671 extends downward for a distance, the depth of the annular groove 22 matches the cutting depth of the cutter 671, ensuring that each cutting can accurately remove excess heat-sealing film while protecting the edge of the bowl body 3 from damage. During use, the heating ring 67 is pressed down to contact the heat-sealing film on the bowl body 3, and the cutter 671 is inserted into the ring groove 22 to cut off the excess film.

[0028] When the bowl body 3 reaches the designated position, the lifting mechanism is started, and the heating ring 67 is first pressed down to contact the heat-sealing film for heating and sealing. Then the cutter 671 is synchronously inserted into the ring groove 22 to cut off the excess film material. The whole process is fast and coherent. After the sealing is completed, the conveyor 1 continues to transport the sealed bowl of porridge to the next process, such as packaging, boxing or quality inspection area.

[0029] When in use, a heating ring 67 and a cutter 671 are provided, the heating ring 67 corresponds to the rim of the bowl, and the cutter 671 extends downward for a distance. During heat sealing, the heating ring 67 presses the heat-sealing film onto the rim of the bowl, and the cutter 671 is inserted into the ring groove 22 to form pressure, cutting the heat-sealing film into the same shape as the rim of the bowl, thereby avoiding incomplete detachment of the heat-sealing film, which causes the bowl to be transported together with the heat-sealing film during transportation, causing the bowl to be stuck in the sealing machine.

[0030] The sealing assembly 6 includes a power box 68, which is fixed to the conveyor 1. The lifting mechanism is arranged in the power box 68. The lifting mechanism includes a crankshaft 62. The rotational motion of the crankshaft 62 is converted into linear motion by a connecting rod 63, thereby driving the heating ring 67 and the cutter 671 to move up and down. The crankshaft 62 is rotatably arranged in the power box 68. The power box 68 is also equipped with a rotary drive member 61 for driving the crankshaft 62 to rotate. The rotary drive member 61 generally adopts an efficient power source such as an electric motor or a pneumatic motor to transmit power to the crankshaft 62, achieving its stable rotational motion. The crankshaft 62 is also provided with a connecting rod 63, and the bottom of the connecting rod 63 is provided with a connecting plate 64 through an axis. The top of the connecting plate 64 is also equipped with four guide rods 641, and the guide rods 641 extend into the power box 68. The four guide rods 641 not only enhance the stability of the connecting plate 64, but also ensure its linear motion during the lifting process, preventing sealing quality problems caused by deviation or shaking.

[0031] During use, when the rotary drive member 61 is activated, the crankshaft 62 begins to rotate. As the crankshaft 62 rotates, the connecting rod 63 drives the connecting plate 64 in an up and down reciprocating motion. The up and down motion of the connecting plate 64 further drives the heating ring 67 and the cutter 671 to rise and fall. When the bowl 3 is transferred to the designated position, the heating ring 67 presses down to contact the heat-sealing film on the bowl 3 to heat and seal it. Subsequently, the cutter 671 is inserted into the annular groove 22 to remove excess film material. Throughout this process, the guide rod 641 ensures the accuracy and stability of the lifting movement.

[0032] A buffer 65 is installed at the center of the bottom of the connecting plate 64. The main function of the buffer 65 is to absorb and mitigate the impact force and vibration generated by the lifting mechanism during its descent. This helps protect the heating ring 67, the bowl 3, and the entire sealing mechanism from damage caused by sudden impact. The buffer 65 is sheathed with a spring 651, and a stamping plate 66 is installed at the bottom of the buffer 65. The heating ring 67 is installed at the bottom of the stamping plate 66. When the lifting mechanism causes the heating ring 67 to contact the bowl 3, the spring 651 will gradually compress. When the lifting mechanism drives the connecting plate 64 to descend, causing the heating ring 67 to contact the bowl 3, the spring 651 will gradually compress, thereby absorbing and dispersing the impact force generated at the moment of contact. This design helps maintain uniform contact force and avoid sealing quality problems or equipment damage caused by excessive local pressure.

[0033] Driven by the lifting mechanism, the connecting plate 64 lowers the buffer 65, spring 651, punching plate 66, and heating ring 67. As the heating ring 67 approaches contact with the heat-sealing film on the bowl body 3, the spring 651 gradually compresses, absorbing and mitigating the impact force generated at the moment of contact. As the spring 651 further compresses, the heating ring 67 makes close contact with the heat-sealing film and begins heating and sealing. Throughout this process, the synergistic effect of the buffer 65 and spring 651 ensures a smooth and reliable sealing operation.

[0034] During use, by providing a buffer 65 and a spring 651, the spring 651 will be gradually compressed under the action of the stamping plate 66, thereby playing a buffering role, avoiding excessive impact force when pressing down to seal, which may cause damage to the device.

[0035] The sealing assembly 6 is also provided with a film conveying assembly 5 , which is used for unwinding the heat-sealing film and rewinding the used heat-sealing film.

[0036] The film conveying assembly 5 includes a guide roller 51, the main function of which is to guide the path of the heat-sealing film during the unwinding and rewinding process, ensuring that the heat-sealing film can be transported smoothly and stably. The guide roller 51 is usually made of wear-resistant and corrosion-resistant materials to ensure stability and reliability under long-term use. Two guide rollers 51 are symmetrically arranged on the sealing assembly 6. The film conveying assembly 5 also includes an unwinding wheel 52 for unwinding the heat-sealing film and a rewinding wheel 53 for rewinding the heat-sealing film. The unwinding wheel 52 serves as the starting point of the heat-sealing film and is responsible for gradually unwinding the rolled heat-sealing film. The film conveying assembly 5 also includes a drive member for driving the rewinding wheel 53 to rotate. When the drive member rotates, the rewinding wheel 53 pulls the heat-sealing film out of the unwinding wheel 52.

[0037] Before the sealing operation begins, the heat-sealing film on the unwinding wheel 52 is pulled out and laid above the bowl body 3 on the conveyor 1 under the guidance of the guide roller 51. As the conveyor 1 runs and the bowl bodies 3 are transported one by one to the sealing position, the heating ring 67 presses down to contact the heat-sealing film to heat and seal. After the sealing is completed, the excess heat-sealing film enters the winding area of ​​the winding wheel 53 under the guidance of the guide roller 51. At this time, the drive starts and drives the winding wheel 53 to rotate, and the used heat-sealing film is wound. Throughout the process, the coordinated work of the unwinding wheel 52 and the winding wheel 53 ensures the continuous supply and timely winding of the heat-sealing film, improving production efficiency and the degree of automation.

[0038] A filling assembly 4 is also installed on one side of the sealing assembly 6. The filling assembly 4 is used to draw the internal material into the bowl body 3 for automatic filling.

[0039] The filling assembly 4 includes a box body 41 for storing materials and a pump body 42 installed on the box body 41. One end of the pump body 42 is connected to a connecting pipe 43, and the other end of the pump body 42 extends to the box body 41 through a pipeline. One end of the connecting pipe 43 is connected to a diversion pipe 44, and a blocking ring 45 corresponding to the bowl body 3 is distributed on the diversion pipe 44. The blocking ring 45 is slightly larger than the bowl body 3. When filling, the blocking ring 45 covers the bowl body 3 to prevent material from splashing.

[0040] A telescopic drive member 46 is also fixed to the bottom of the box body 41. The output end of the telescopic drive member 46 is fixedly connected to the diversion pipe 44. The telescopic drive member 46 is used to move the diversion pipe 44 downward to facilitate the blocking ring 45 to cover the bowl body 3 for filling.

[0041] During use, before the filling process begins, material is first added to the tank 41 and the pump 42 is activated. The pump 42 draws the material from the tank 41 through a pipeline and delivers it to the diverter pipe 44 via a connecting pipe 43. When the conveyor 1 transports the bowl 3 to the filling position, the barrier ring 45 on the diverter pipe 44 automatically covers the bowl 3. At this point, the pump 42 continues to operate, pumping the material through the gap between the diverter pipe 44 and the barrier ring 45 into the bowl 3. The sealing effect of the barrier ring 45 prevents material from splashing during the filling process, ensuring accurate and hygienic filling.

[0042] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
