Embodiment 1

[0044] The embodiment of the present application discloses a buffer material forming process. refer to figure 2, is a kind of molding equipment used in the implementation of this process, including core mold 3, side pressure mold 4, hydraulic cylinder 5, heating rod 6 and frame 7 and other components, wherein, core mold 3 and side pressure mold 4 They are all arranged in the shape of long straight rods. The core mold 3 and the side pressure mold 4 are made of heat-conducting metal materials. For example, in this embodiment, the core mold 3 and the side pressure mold 4 are made of cast iron, and they can also be made of aluminum alloy or Made of copper alloy material. The mandrel 3 is arranged along the horizontal direction, and one end of the mandrel 3 is fixedly installed on the frame 7. The cross section of the mandrel 3 is arranged in a U-shape, which is consistent with the shape of the inner edge of the packaging buffer material 2. The mandrel 3 is used for The paper su...

Embodiment 2

[0063] The difference between this embodiment and Embodiment 1 is that the working pressure of the hydraulic cylinder is 2.5 tons, the thickness of the paper tube is 2 mm, the baking temperature is 120 degrees Celsius, and the holding time of the extrusion action is set to 60 s.

[0064] Experiments have shown that if a 24-inch display screen is selected, the buffer packaging material is set to the side of the display screen, and the display screen is dropped from a height of 0.5 meters. After repeated 10 times, the screen display is normal and undamaged, which meets the requirements Requirements.

Embodiment 3

[0066] The difference between this embodiment and Embodiment 1 is that the working pressure of the hydraulic cylinder is 3 tons, the thickness of the paper tube is 3 mm, the baking temperature is 130 degrees Celsius, and the holding time of the extrusion action is set to 70 s.

[0067] Experiments have shown that if a 24-inch display screen is selected, the buffer packaging material is set to the side of the display screen, and the display screen is dropped from a height of 0.5 meters. After repeated 10 times, the screen display is normal and undamaged, which meets the requirements Requirements.

Abstract

The invention relates to the field of paper product forming processes, in particular to a buffer material forming process. According to the technical scheme, the buffer material forming process is characterized by comprising the following steps that S1, a base material is prepared, a paper tube is used as the base material, and the paper tube is a kraft paper tube; S2, equipment is debugged, equipment is provided with a core mold and side pressing molds located at one side of the core mold, the number of the side pressing molds is four, the four side pressing molds are located at the upper side, the lower side, the left side and the right side of the core mold correspondingly, and the side pressing molds and the core mold are heated; S3, the base material is placed, specifically, the paper tube is connected to the core mold in a sleeving manner so as to be placed; S4, the equipment is started, so that the side pressing molds move towards the core mold and are combined with the core mold, and the paper tube is extruded and deformed; S5, the extrusion action is kept, and the paper tube is baked and hardened through the side pressing molds and the core mold; S6, the equipment is started, and the side pressing molds return; and S7, a workpiece is taken out of the core mold. The process has the effects of improving the production process of a buffer material and further improving the production quality of the buffer material.

Description

technical field [0001] The present application relates to the field of paper molding technology, in particular to a buffer material molding technology. Background technique [0002] Cushion packaging can also be called shockproof packaging. From the completion of production to delivery of industrial products, it usually involves logistics links such as transportation, storage, stacking, and loading and unloading. In any link, external forces act on the product. Here, The so-called cushioning packaging refers to the packaging that takes certain protective measures to slow down the impact and vibration of the product and reduce damage, and is widely used in production and life. [0003] At present, the widely used cushioning materials are mainly foam cushioning materials and paper cushioning materials. On the one hand, foam cushioning materials mainly use plastics and rubber as raw materials, and are obtained by foaming and expanding through foaming technology, which has corro...
