[0026] like Figure 1 and Figure 2 As shown, this double-turntable bowl packaging machine includes a machine base and a first turntable A, and the first turntable A is rotatably mounted on the machine base 9. Figure 3 As shown, a plurality of first bowl placement positions A0 are equally divided along the circumference of the first turntable A, and each first bowl placement position A0 is provided with a first bowl placement hole A00. Figure 5 As shown, the first turntable A has a bowl placing station A1, a material adding station A2 and a bowl taking out station A4. The bowl placing station A1 is used to place the bowl into the first bowl placing hole A00, the material adding station A2 is used to add materials into the bowl, and the bowl taking out station A4 is used to take out the bowl.

[0027] like Figure 1 and Figure 2 As shown, a second turntable B is rotatably mounted on the base 9, and the second turntable B is connected to a turntable power source for driving the second turntable B to rotate. Figure 4As shown in the figure, a plurality of second bowl - placing positions B0 are provided along the circumference of the second turntable B. Each second bowl - placing position B0 is provided with a second bowl - placing hole B00. The second turntable B has a bowl - loading station B1, a bowl - sealing station B2, and a bowl - unloading station B4. The bowl - loading station B1 is used to place the bowls on the bowl - placing positions A4 of the first turntable A onto the second bowl - placing holes B00. Therefore, the bowl - placing position A4 of the first turntable A is close to the bowl - loading station B1 of the second turntable B. The bowl - sealing station B2 completes the bowl - sealing work, and the bowl - unloading station B4 is used to remove the sealed bowls. In order to take out the bowls on the first turntable A, a bowl - lifting mechanism 4 is provided below the bowl - placing position A4 of the first turntable A. As Figure 7 shown, the bowl - lifting mechanism 4 includes a bowl - lifting member 40 and a bowl - lifting power source for driving the bowl - lifting member 40 to move up and down. Driven by the bowl - lifting power source, the bowl - lifting member 40 lifts the bowl located at the bowl - placing position A4. Above the bowl - placing position A4 of the first turntable A, a bowl - feeding mechanism 5 is provided. As Figure 8 shown, the bowl - feeding mechanism 5 includes a bowl - grasping hand and a bowl - feeding power source 54 for driving the bowl - grasping hand to move between the bowl - placing position A4 of the first turntable A and the bowl - loading station B1 of the second turntable B. When the bowl at the bowl - placing position A4 is lifted, the bowl - grasping hand grabs the bowl, and then driven by the bowl - feeding power source 54, the bowl - grasping hand brings the bowl to the bowl - loading station B1 of the second turntable B and finally places it into the second bowl - placing hole B00 of the second turntable B.

[0028] The working principle of this double - turntable bowl - type packaging machine is as follows: As Figure 5 shown, the first turntable A rotates driven by a power source. The first turntable A has a bowl - placing station A1, a feeding station A2, and a bowl - placing position A4. At the bowl - placing station A1, the bowl - placing mechanism 1 places empty bowls into the first bowl - placing holes A00 of the first turntable A. As the first turntable A rotates, the empty bowls reach the feeding station A2 of the first turntable A. At the feeding station A2, the feeding mechanism 2 adds the materials to be packaged into the bowls (as Figure 8 shown, the feeding mechanism 2 includes a hopper 20 and a material - control plate 21 for controlling the feeding). Then, as the first turntable A rotates, the bowls filled with materials reach the bowl - placing position A4. At the bowl - placing position A4, the bowl - lifting member 40 of the bowl - lifting mechanism 4 lifts the bowl, and then the bowl - grasping hand of the bowl - feeding mechanism 5 grabs the lifted bowl and transports it to the second turntable B. As Figure 5As shown in the figure, the second turntable B has an upper bowl station B1, a bowl sealing station B2, and a lower bowl station B4. Among them, the upper bowl station B1 of the second turntable B is close to the bowl outlet station A4 of the first turntable. After the bowl gripper of the bowl feeding mechanism 5 grabs the bowl, it is transported to the second bowl placing hole B00 at the upper bowl station B1. As the second turntable B rotates, the bowl reaches the bowl sealing station B2. At the bowl sealing station B2, the bowl sealing mechanism 6 seals the bowl mouth with a film. Then, as the second turntable B rotates, the sealed bowl reaches the lower bowl station B4. At the lower bowl station B4, the lower bowl mechanism 8 removes the sealed bowl, thus completing all the work.

[0029] Since the feeding work is completed on the first turntable A and the bowl sealing work is completed on the second turntable B, the juice dripping or food falling during feeding will only fall on the first turntable A, making the bowl cleaner and more hygienic during packaging on the second turntable B. At the same time, since two turntables are made, the area of each turntable can be made smaller, greatly reducing the manufacturing difficulty.

[0030] In order to smoothly place the bowl into the second bowl placing hole B00 of the second turntable B, a bowl supporting mechanism 90 is provided below the upper bowl station B1 of the second turntable B. As Figure 1 shown, the bowl supporting mechanism 90 includes a bowl supporting member and a bowl supporting power source for driving the bowl supporting member to move up and down (the structure of the bowl supporting mechanism 90 is the same as that of the bowl lifting mechanism 4, and the figure can be referred to Figure 7 ). The bowl feeding mechanism 5 delivers the bowl, making the bowl directly above the second bowl placing hole B00 of the second turntable B. At this time, the bowl supporting member passes through the second bowl placing hole B00 and waits below the bowl. When the bowl gripper of the bowl feeding mechanism 5 puts down the bowl, the bowl is placed on the bowl supporting member. Then, the bowl supporting power source drives the bowl supporting member to move down, so that the bowl on the bowl supporting member moves down and is placed in the second bowl placing hole B00 of the second turntable B. Of course, a structure for moving the bowl gripper of the bowl feeding mechanism 5 up and down can be added, such as adding a cylinder to drive the bowl gripper to move up and down, so that the bowl can also be smoothly placed into the second bowl placing hole B00 of the second turntable B. It is worth mentioning here that the bowl supporting power source and the bowl lifting power source can be independent power sources (such as motors or cylinders), or a main power source can be transmitted through a transmission structure (such as a cam).

[0031] In order to improve the packaging efficiency and feed multiple bowls at a time, as Figure 5 described, each first bowl placing position A0 of the first turntable A is provided with two or more first bowl placing holes A00 (including two); similarly, in order to seal multiple bowls at a time, each second bowl placing position B0 of the second turntable B is provided with two or more second bowl placing holes B00 (including two).

[0032] As Figure 8As shown in the figure, the bowl-gripping hand includes a gripper seat 50, a left gripper 51, a right gripper 52, and a gripper power source 55. The gripper power source 55 is installed on the gripper seat 50. The left gripper 51 and the right gripper 52 can move relative to each other driven by the gripper power source 55 (the gripper power source 55 can be a cylinder). After the bowl is lifted up by the bowl-lifting mechanism 4, the gripper power source 55 drives the left gripper 51 and the right gripper 52 to grip the bowl, and then the bowl-feeding power source 54 drives the gripper seat 50 to move on the guide rail 53. It should be noted here that the bowl-feeding power source 54 and the guide rail 53 can be replaced by a linear module.

[0033] In order to make the materials in the bowl more flat, as Figure 5 shown, the first turntable A also has a material-poking station A3, which is located between the feeding station A2 and the bowl-discharging station A4. As Figure 2 shown, a material-poking mechanism 3 is provided at the material-poking station A3. The material-poking mechanism 3 includes a material-poking head and a material-poking power source for driving the material-poking head to move up and down. After the bowl is filled at the feeding station A2, the first turntable A rotates, and the bowl comes to the material-poking station A3. Driven by the material-poking power source, the material-poking head pokes the materials downward to level the materials in the bowl, ensuring smooth subsequent packaging.

[0034] As Figure 9 and Figure 10 shown, a bowl-sealing mechanism 6 is provided at the bowl-sealing station B2 of the second turntable B. The bowl-sealing mechanism 6 includes a heat-sealing head 60 and a film-guiding roller 61. The film-guiding roller 61 guides the film over, and then the heat-sealing head 60 heat-seals the film to the bowl mouth.

[0035] In order to extend the shelf life of the food, it is necessary to evacuate the bowl and then perform heat-sealing. For this reason, the bowl-sealing mechanism 6 also includes an upper vacuum cover 62 and a lower vacuum cover. The upper vacuum cover 62 and the lower vacuum cover can form a vacuum chamber. Of course, the heat-sealing head 60 is located inside the upper vacuum cover 62. After the upper vacuum cover 62 and the lower vacuum cover are closed, evacuation is performed, and after completion, the heat-sealing head 60 operates for packaging.

[0036] In order to make the connection between the film and the bowl mouth more firm, the second turntable B also has a secondary-sealing station B3, which is located between the bowl-sealing station B2 and the bowl-discharging station B4. A secondary-sealing mechanism 7 is provided at the secondary-sealing station B3. The secondary-sealing mechanism includes a secondary heat-sealing head. After the bowl is subjected to primary heat-sealing at the bowl-sealing station B2, the second turntable B rotates, and the bowl comes to the secondary-sealing station B3. The secondary heat-sealing head of the secondary-sealing mechanism 7 performs secondary heat-sealing on the bowl mouth to further strengthen the adhesion between the film and the bowl mouth.

[0037] After the bowl is packaged, it needs to be removed. Therefore, a bowl-removing mechanism 8 is provided at the bowl-discharging station B4 of the second turntable B. As Figure 11As shown in the figure, the lower bowl mechanism 8 includes a bracket 80, a suction cup 81, a sliding seat 82, and a lifting power source 84. A guide rail 83 is provided on the bracket 80. The sliding seat 82 is slidably arranged on the guide rail 83. The lifting power source 84 is installed on the sliding seat 82 and can drive the suction cup 81 to move up and down. The sliding seat 82 is in transmission connection with a lower bowl power source 86 that drives the sliding seat 82 to move on the guide rail 83. When the bowl reaches the lower bowl station B4 of the second turntable B, the lifting power source 84 drives the suction cup 81 to move downwards. The suction cup 81 sucks the film on the bowl. Then the lifting power source 84 drives the suction cup 81 to move upwards. The suction cup 81 sucks the bowl out from the second bowl discharging hole B00 of the second turntable B. Finally, the lower bowl power source 86 drives the sliding seat 82 to move, sending the bowl outside, thus completing all the packaging work.

[0038] Finally, it is worth mentioning that a bowl placing mechanism 1 is provided at the bowl placing station A1 of the first turntable A, as Figure 6 shown. The bowl placing mechanism 1 includes a bowl placing bracket 12, a bowl groove 10, and a bowl placing rotating vane 11. The bowl groove 10 is installed on the bowl placing bracket 12. The bowl placing rotating vane 11 is rotatably installed on the bowl placing bracket 12 and is in transmission connection with a bowl placing power source that drives the bowl placing rotating vane 11 to rotate. Bowls are stacked together in the bowl groove 10. The bowl placing rotating vane 11 supports the edge of the lowermost bowl to prevent the bowl from falling. As the bowl placing power source drives the bowl placing rotating vane 11 to rotate, the bowl placing rotating vane 11 no longer supports the lowermost bowl. Each time the bowl placing rotating vane 11 rotates one circle, one bowl drops, so that the bowls drop one by one.
