Conventional operations mostly use fixed-shape molds with heating functions to perform hot pressing to ensure the aesthetics and flatness of the final product. However, the current hot pressing device uses a high temperature. In particular, when the operator directly removes the paper-plastic packaging bag that has just been hot-pressed from the hot pressing device, improper operation can easily cause burns, posing a certain safety hazard. In view of this, it is necessary to improve the current hot pressing and shaping to solve the above problems.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0024] Reference Figure 1-4 A paper-plastic bag hot pressing and shaping device includes a base 1, a table 2, a storage platform 12, and an extrusion plate 5. A controller 14 is mounted on the base 1 via a bracket 3. Hydraulic cylinders 4 are symmetrically arranged on the horizontal portion of the bracket 3. The telescopic portion of the hydraulic cylinder 4 passes through the horizontal portion of the bracket 3. The extrusion plate 5 is horizontally arranged between the bottom end surfaces of the telescopic portion of the hydraulic cylinder 4, and the bottom end surface of the extrusion plate 5 is provided with an electric heating plate 6.

[0025] In other embodiments, the controller 14 is electrically connected to the hydraulic cylinder 4 and the electric heating plate 6 respectively;

[0026] Through this design, the hydraulic cylinder 4 and the motor heating plate 6 are electrically connected to the controller 14, which makes it easier for the operator to use and control the hot pressing and shaping device through the controller 14. The controller 14 can raise and lower the telescopic part of the hydraulic cylinder 4 through electrical signals, and at the same time, the controller 14 can also increase the temperature of the electric heating plate 6.

[0027] A platform 2 is provided in the middle of the top surface of the base 1, and a plurality of through holes 7 are opened at equal intervals on the platform 2. A cover 10 is provided on the top surface of the through holes 7. An inverted T-shaped block 9 is slidably inserted in the middle of the cover 10. A storage platform 12 is horizontally provided between the inverted T-shaped blocks 9, and a paper-plastic bag body 13 is placed flat on the storage platform 12.

[0028] In other embodiments, the storage platform 12 is made of aluminum, and the thickness of the storage platform 12 is 2 mm to 4 mm;

[0029] Through this design, the storage platform 12 is designed to be a thin aluminum plate with a thickness of 2mm-4mm. Metal aluminum has good heat dissipation function, which helps to quickly dissipate heat from the paper-plastic bag body 13 after hot pressing;

[0030] The inverted T-shaped block 9 includes a vertical portion and a horizontal portion, wherein the vertical portion of the inverted T-shaped block 9 passes through the cover plate 10 , and the horizontal portion of the inverted T-shaped block 9 is located inside the through hole 7 .

[0031] In other embodiments, a spring 11 is provided on the bottom wall inside the through hole 7, and the top end surface of the spring 11 is fixedly connected to the bottom end surface of the horizontal portion of the inverted T-shaped block 9;

[0032] Through this design, when the spring 11 is in a natural rebound state, the storage platform 12 is away from the table 2. At this time, the storage platform 12 suspends the paper-plastic bag body 13 to facilitate air circulation for cooling. When the hydraulic cylinder 4 drives the electric heating plate 6 under the extrusion plate 5 to perform hot pressing operation on the paper-plastic bag body 13, when the spring 11 is in a compressed state, the storage platform 12 and the table 2 fit together, thereby better ensuring the contact between the electric heating plate 6 and the paper-plastic bag body 13.

[0033] In other embodiments, the inner wall of the through hole 7 is provided with a wear-resistant rubber layer.

[0034] With this design, the wear-resistant rubber layer is arranged on the inner wall of the through hole 7. When the spring 11 is repeatedly deformed, the wear-resistant rubber layer can reduce the wear caused by the horizontal portion of the inverted T-shaped block 9 and the outer side of the spring 11 on the inner wall of the through hole 7, thereby improving the service life of the hot pressing shaping device.

[0035] In this embodiment, a through hole is opened on the table, and a storage platform for placing the paper-plastic bag body is elastically provided in the through hole by a spring and an inverted T-shaped block. The storage platform is made of a thin plate material of aluminum material, which can quickly dissipate heat. In addition, the hot pressing and shaping device is reset upward with the hydraulic cylinder after the hot pressing is completed, which is convenient for the operator to take and place the paper-plastic bag body, reducing the occurrence of safety hazards such as burns.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
