Description

Technical Field

[0001] This utility model relates to the field of cardboard packaging material processing technology, and more specifically, it relates to a thermoforming equipment for multi-layer composite cardboard materials. Background Technology

[0002] With the continuous development of the packaging industry, multi-layer composite cartons have been widely used due to their advantages such as high strength, low cost, and reusability.

[0003] In existing thermoforming equipment for multi-layer composite cardboard boxes, the heating elements are not evenly distributed, resulting in significant temperature differences in different areas within the mold. This uneven heating of the multi-layer composite cardboard material directly affects the forming quality of the boxes. Furthermore, the mold's structural design is inadequate, hindering easy disassembly. Existing molds are typically fixed to the equipment, requiring mold replacement to accommodate different box sizes or shapes, a cumbersome and time-consuming process. This not only increases downtime and reduces production efficiency but also risks mold damage due to improper operation during replacement, further increasing production costs. Utility Model Content

[0004] To address the problem of uneven heating element distribution in existing multi-layer composite cardboard box material thermoforming equipment, which leads to significant temperature differences in different areas of the mold and consequently uneven heating of the multi-layer composite cardboard box material, directly affecting the forming quality of the cardboard box, and further compromising the design of the forming mold, this invention aims to provide a multi-layer composite cardboard box material thermoforming device. This device addresses the issue of uneven heating element distribution in existing equipment, resulting in significant temperature differences within the mold and consequently, uneven heating of the multi-layer composite cardboard box material. Furthermore, the existing mold design is inefficient, hindering easy disassembly.

[0013] The advantages of this utility model are: 1. This utility model uses bolts and nuts to fix the connecting plate and forming mold onto the support frame. The detachable design allows for quick disassembly, significantly reducing mold change time. This is particularly important for the production of multi-specification and multi-shape cartons, effectively improving production efficiency. By replacing molds of different shapes and sizes, it adapts to the production needs of various carton specifications, enhancing the equipment's versatility and flexibility. The bolt and nut connection provides sufficient mechanical strength, ensuring the stability and safety of the mold during the thermoforming process. During thermoforming, the mold may be subjected to vibration and impact forces; the bolt connection effectively resists these forces, maintaining the mold's fixed position and preventing loosening.
