Description

Technical Field

[0001] The utility model mainly relates to the technical field of paper cup machines, in particular to a paper cup bottom sealing device. Background Art

[0002] The paper cup machine needs to perform operations such as paper feeding, cup body sealing and bottom sealing during the paper cup production process. Before the bottom sealing operation, the sealed cup body needs to be placed in the mold, and the cup body is squeezed and fitted into the mold through the pressing plate above the mold. The feeding punch below the mold pushes the cup bottom to the bottom of the cup body and seals it.

[0003] The existing patent (Announcement No.: CN218804290U) discloses a cup bottom forming device, which is used in a paper cup machine and includes: a preforming device, which includes a preforming mold and a first power device, the preforming mold has a forming recess and a central opening, wherein the first power device actuates the preforming mold to move toward or away from the bottom of the paper cup, so that the forming recess can pre-bend the bottom of the paper cup; and a bending forming device, which includes a bending forming mold and a second power device, wherein the bending forming mold has a punch, which can be actuated by the second power device to pass through the central opening of the preforming device so that the bottom of the paper cup continues to bend and complete the forming of the bottom. In this way, the cup bottom is formed by means of two molds in two separate actions, which can prevent the surface of the paper cup from being scratched without the need for lubricants, thereby improving product quality and reducing costs.

[0004] In the process of implementing the solution, the inventor sent the unsealed cup body into the mold, and there was a certain probability that the conical cup body would be deformed, resulting in the inability to seal the cup body with the cup bottom normally. The inventor proposed a paper cup bottom sealing device, which cooperates with the paper cup machine to complete the positioning and assembly of the cup body in the mold to avoid deformation of the cup body before the bottom is sealed.
