When the hot pressing head 110 is withdrawn, the return spring 200 can quickly push the limit pin 170 out and return to the initial position, facilitating the next process. This automatic reset function ensures the accuracy and consistency of each packaging, improving production efficiency and ease of operation.

[0036] There are three stop pins 170, which are spaced 120 degrees apart along the circumference of the through hole 190. The even distribution of the three stop pins 170 effectively prevents the aluminum film from shifting during the hot pressing process, ensuring that the aluminum film can be smoothly and evenly attached to the bowl body, thereby improving the uniformity and sealing of the seal.

[0037] There are four retaining pins 170, spaced 90° apart along the circumference of through-hole 190.

The even distribution of the four retaining pins 170 effectively prevents the aluminum film from shifting during the hot pressing process, ensuring that the aluminum film adheres smoothly and evenly to the bowl body, improving the uniformity and tightness of the seal.

[0038] The bowl-sealing device includes two sets of heating components, spaced apart along the conveyor belt 150 to form an observation station 140. By spacing the two heating components apart, the second heating component can perform secondary heating after the first heating component completes the initial seal, ensuring uniformity and reliability of the seal and improving sealing quality. The design of observation station 140 allows operators to easily observe and adjust the sealing process, ensuring optimal sealing of each bowl and reducing scrap.

[0039] A buffer spring 130 is provided between the drive base and the hot pressing head 110. One end of the buffer spring 130 abuts the hot pressing head 110, and the other end abuts the top of the hot pressing head 110. The buffer spring 130 ensures that the hot pressing head 110 presses down smoothly when contacting the aluminum film, preventing deformation or damage to the aluminum film due to sudden impact, and ensuring uniform sealing and tightness. The elastic design of the buffer spring 130 enables the hot pressing head 110 to adapt to aluminum films of varying thicknesses, ensuring optimal sealing results each time, and improving the versatility and flexibility of the device.

[0040] The through hole 190 is circular, and the shape of the through hole 190 is adapted to the bowl body. The precise matching of the circular through hole 190 and the shape of the bowl body can ensure that the bowl body is firmly fixed in the through hole 190 during the film sealing process, avoiding poor sealing caused by position deviation.

[0042] The heating assembly also includes a guide rod 120, which is positioned on one side of the heat press head 110 and extends vertically. This rod ensures smooth vertical movement of the heat press head 110 during both the downward and retracting processes, preventing lateral deviation and improving the accuracy and consistency of the seal. The provision of the guide rod 120 enhances the stability of the heat press head 110, reduces motion errors caused by equipment vibration or external interference, and ensures uniform and reliable sealing every time.

[0043] The number of hot pressing heads 110 matches the number of through holes 190, and the positions of the hot pressing heads 110 and the through holes 190 correspond one to one. This ensures that each hot pressing head 110 can accurately align with the corresponding bowl body, avoiding poor sealing due to position offset and improving sealing accuracy and consistency.

[0044] Reference Figures 1 to 3, this embodiment provides a bowl body sealing device, which is used for the aluminum film sealing and heat treatment of the bowl body.

The mutual adaptation of the alignment blocks 180 and the inner recess ensures that the hot pressing head 110 can accurately align with the bowl during the pressing process, improving the accuracy and consistency of the sealing.

[0046] In the previous process, the bowl body and the aluminum film have been pre-assembled, and the aluminum film covers the opening of the bowl body. Four limiting pins 170 are circumferentially arranged on the outer side of the through hole 190. The limiting pins 170 are arranged at 90° intervals along the circumference of the through hole 190. When the aluminum film is placed in the through hole 190, the limiting pins 170 can clamp the aluminum film to ensure that the aluminum film does not shift during the hot pressing process. The assembled bowl body is transported to the bottom of the heating assembly by the conveyor belt 150, and the drive seat drives the hot pressing head 110 to move downward. During the downward pressing process of the hot pressing head 110, the buffer spring 130 absorbs the impact force to ensure that the hot pressing head 110 contacts the aluminum film smoothly. The hot pressing head 110 contacts the aluminum film, so that the aluminum film and the bowl body form a closed cavity. The temperature and pressure of the hot pressing head 110 ensure that the aluminum film can be evenly heated and firmly attached to the opening of the bowl body, completing the sealing process. After the hot pressing head 110 completes the sealing, it retracts upwards, and the limiting pin 170 automatically extends under the action of the return spring 200 and returns to the initial position, making it convenient for the next process.
