Abstract
Description
Technical Field
[0001] The utility model relates to a sealing machine, in particular to a sealing machine for hot-pressing and sealing beverage cups, belonging to the field of beverage production. Background Art
[0002] In the packaging fields of freshly squeezed beverages and various dairy products, a sealing machine, that is, a heat-sealing machine, is often used. After placing the product in the packaging container, it can be sent to the sealing machine for hot-pressing and sealing. In the field of freshly squeezed beverages, the packaging container is generally a packaging cup. The existing packaging cups in the prior art are frustum-shaped cups with a large opening, and there is an annular outward-turning edge at the position of the mouth edge. The structure on the sealing machine for supporting the cup uses a film to seal the cup mouth, then uses a hot-pressing method to press the film tightly on the cup mouth, and finally cuts the cup from the film. The current sealing machine has a frame, and there is an installation opening on the frame. The installation opening is a U-shaped notch, and the opening of this U-shaped notch faces one side. Here, one side is relative to the upper and lower ends. The frame has four sides, and this installation opening faces one side. Above the installation opening, there is a sealing film and a heat-sealing device. The installation opening is used to place the beverage cups to be packaged. Specifically, a positioning plate and a support plate are horizontally slidably arranged in the installation opening. Both the positioning plate and the support plate can slide into the interior of the installation opening and can also slide to the outside of the installation opening. Moreover, the support plate is located below the positioning plate and can move up and down relative to the positioning plate. A beverage cup insertion opening is provided on the positioning plate, and the support plate is used to support the bottom of the beverage cup to position the beverage cup. During operation, the positioning plate and the support plate synchronously move outward through their respective power devices, that is, move outward from the installation opening. The operator puts the cup into the beverage cup insertion opening of the positioning plate, and the bottom of the cup falls on the support plate. The positioning plate and the support plate synchronously move inward through their respective power devices. After reaching the designated position, the support plate moves upward to support the cup to contact the sealing film and the heat-sealing device to complete the sealing. Then, the support plate moves downward and moves outward together with the positioning plate to send out the cup to complete the sealing work, and the operator can take away the sealed cup. In the existing sealing machine, there is no protection against pinching hands at the cup position. When sealing, the distance between the support plate and the positioning plate decreases as the support plate moves upward. If the operator accidentally puts his hand between the positioning plate and the support plate, it is dangerous. Moreover, there have been many cases of fingers being cut in the market, and the safety problem of the sealing machine needs to be solved. Summary of the Utility Model
