Description

Technical Field

[0001] The utility model relates to the technical field of cardboard packaging, in particular to a steam-type packaging cardboard molding device. Background Art

[0002] In the existing packaging technology, due to the characteristics of convenient recycling, low production cost, and simple and easy-to-control production process, packaging cardboard has been widely used in various industries; for example, packaging cardboard for cosmetics, electronic products, computers, mobile phones, packaging cushions for machining products, food packaging, food packaging, and beverage product packaging.

[0003] In the prior art, the production of packaging cardboard first involves the recycling of paper materials in the early stage, and then the initial molding work. The initial molding work is to make a cardboard structure with a preliminary model from pulp products through a mold. However, in this process, serious deformation of the cardboard will occur after the pulp products are air-dried. Therefore, secondary molding work is required. The secondary molding is carried out by pressing with a designed and matched mold. When the cardboard is already air-dried, it can be directly pressed to produce a formed cardboard structure, which can be directly used as packaging cardboard.

[0004] The secondary molding mechanisms in the prior art directly press the cardboard, and it is very easy to damage the cardboard during the whole pressing process. If the cardboard is deformed greatly, it will be directly crushed by the template, and the pressing effect and quality are relatively poor.

[0005] In addition, although large-scale cardboard production is carried out in the prior art and the shapes and structures are already fixed, sometimes it is also necessary to press cardboard of different shapes. However, the upper and lower molds in the prior art are fixedly installed and cannot be effectively replaced, resulting in inconvenient use.

[0006] Therefore, in order to solve the above problems, it is necessary to develop a steam-type packaging cardboard molding device with a reasonable structure, which can improve the packaging performance and product transportation safety. Content of the Utility Model

[0007] The purpose of the utility model is to provide a steam-type packaging cardboard molding device aiming at the deficiencies of the prior art; the technical solution is as follows:

[0008] A steam-type packaging cardboard molding device includes a workbench, an inner groove is arranged on the workbench, and a detachable lower template is correspondingly installed in the inner groove. The lower template is of an overall concave structure. The space on the upper end surface of the lower template is set as a packaging cardboard molding cavity, and a steam cavity is formed between the lower end surface and the inner groove. A steam device is arranged outside the workbench, and an air delivery pipe is arranged on the steam device. The air delivery pipe is correspondingly connected to the steam cavity to correspondingly deliver steam into the steam cavity.

[0009] Above the workbench, a pressing device is further provided. The main shaft of the pressing device extends downward, and a mounting plate is provided at the shaft end. A detachable upper template is correspondingly mounted at the lower end of the mounting plate. A punch is provided on the lower end surface of the upper template, and the position of the punch corresponds to the position of the packaging cardboard cavity below. After the upper template moves downward, the punch is correspondingly pressed into the packaging cardboard cavity.

[0010] Further, a steam cavity is provided in the upper template, and a steam pipe is correspondingly provided by the steam equipment and connected to the steam cavity of the lower template.

[0011] Further, an air outlet cavity is also provided in the workbench. The air outlet cavity is arranged below the steam cavity in the workbench, and the air outlet cavity and the steam cavity are correspondingly connected through a communication pipe. A recycling device is also provided outside the workbench, and the air outlet cavity and the recycling device are correspondingly connected through a recycling pipe. The recycling device sends the recycled steam back to the steam equipment.

[0012] Further, the steam cavity in the lower template is connected to the recycling device through a recycling pipeline. The hot steam in the steam cavity of the lower template is recycled by the recycling device and then sent into the steam equipment for recycling.

[0013] Further, support columns are also provided in the inner groove to correspondingly support the lower template through the support columns; and support columns are also provided in the steam cavity of the upper template.

[0014] Further, both sides of the lower template are correspondingly mounted at the upper ends of both sides of the inner groove through detachable fixing parts; and the lower template is provided with a corresponding number of sets of template structures according to the shape of the packaging cardboard actually being molded.

[0015] Further, both sides of the upper template are correspondingly detachably mounted on both sides of the mounting plate through detachable fixing parts; the punch of the upper template corresponds to the shape of the lower template and is correspondingly provided with different template structures.

[0016] Beneficial effects: The present utility model has the following beneficial effects:

[0017] 1) In this device, an inner groove is provided on the workbench, and the lower template is mounted on the inner groove. However, the upper end surface of the lower template is set as the packaging cardboard cavity, and a steam cavity is provided between the lower template and the inner groove. Then, a steam equipment is connected to the steam cavity, and after steam is introduced into the steam cavity, when specifically molding, the air-dried and deformed pulp cardboard is placed in the packaging cardboard cavity and pressed by the lower template above.

[0019] 3) In this device, an air outlet cavity is also arranged inside the workbench. This air outlet cavity is arranged below the steam cavity and is correspondingly connected through a connecting pipe. And a recovery device is arranged outside. Then, when the steam device sends steam into the steam cavity, the steam heats the upper template in the steam cavity, and then enters the air outlet cavity through the connecting pipe and is recovered by the recovery device. After that, the steam is sent back to the steam device by the recovery device to form a cycle of hot steam. On the one hand, the steam heat is continuously maintained. And since the air outlet cavity is also arranged inside the workbench, when recovering, the heat will not be wasted, and the heat can still be absorbed by the steam cavity above; On the other hand, it keeps the gas circulating and will not cause situations such as excessive steam pressure;

[0020] 4) In this device, a steam cavity is also arranged in the upper template. Using the same method, the steam can circulate. The advantage of such a setting is that from the upper position, the upper template is also heated by steam. The upper template and the lower template together perform hot steam pressing on the cardboard to be molded, with better effect, faster onset, and more reasonable structure.
