Description

Technical Field

[0001] The invention patent relates to the field of foam packaging materials, and in particular to a method for preparing foam packaging materials and a roller press for producing foam packaging materials. Background Art

[0002] Foam is a material made of plastic particles that have been expanded. It is also called foam. Foam has a series of properties that make it widely used in packaging and other fields. First, foam is elastic, which means it can adapt to different shapes and sizes and provide better protection. Secondly, foam is lightweight, which makes it more convenient to transport and store. In addition, foam's quick pressure-sensitive fixation and easy bending make it easy to handle and process. Most importantly, foam is ultra-thin and reliable, which can effectively protect the items inside from damage.

[0003] With respect to the above-mentioned related technologies, the inventors found that the existing foam materials are generally simply foamed and then cut, and their shapes are single and all are block structures. For the current cylindrical foam materials, their cutting is complicated and the molding scheme is not good, resulting in poor mechanical properties and strength of the prepared foam materials, which affects the actual production efficiency. Summary of the invention

[0004] In order to solve the above technical problems, the present application provides a method for preparing a foam packaging material and a roller press for producing the foam packaging material.

[0005] In the first aspect, the present application provides a method for preparing a foam packaging material using the following technical solution:

[0006] A method for preparing a foam packaging material comprises the following steps:

[0007] The material in the foam packaging material is placed in a mixing device, and after the mixing is completed, it is placed in an extruder to collect the extruded material;

[0008] The extruded material is placed on the surface of a cylindrical mold, and the two ends of the mold are respectively placed on the first set of rollers and the second set of rollers of the roller press, and then the surface is rolled by a long roller, and the rolling strength and the thickness of the foam packaging material are adjusted, and the rolling process is performed;

[0009] After the rolling is completed, the rolled material is collected and placed in a drying device. After drying, the foam packaging material can be prepared.

[0010] Through the above technical solution, the present application performs roller forming after extrusion of the material. On the one hand, the present application improves the combination performance and mixing uniformity between the materials through extrusion. Secondly, the technical solution of roller forming can rely on the opposite rotation of the rollers. The material passing through the gap between the rollers is subjected to the shear force in the calendering direction and the extrusion force perpendicular to the calendering direction to become a product of a fixed shape. Due to the calendering effect, the macromolecules of the product obtain a certain orientation in the calendering direction, so that it has good and stable structural strength and mechanical properties.

[0011] Preferably, the drying process is to dry the foam packaging material until the moisture content is 10-30%.

[0012] Through the above technical scheme, the present application further optimizes the moisture content of the foam packaging material. By optimizing the moisture content of the foam packaging material, the foam packaging material can maintain good humidity and performance under appropriate moisture content conditions, thereby preventing the problem of poor packaging performance of the packaging material due to excessively high or low humidity.

[0013] In a second aspect, the present application provides a roller press including the following technical solutions:

[0014] A roller press comprises:

[0015] Rack body;

[0016] A rolling assembly is arranged on the frame body and is provided with a long roller and a sleeve roller assembly which are arranged relatively at intervals. The sleeve roller assembly includes two sleeve rollers which are coaxially arranged at intervals. The two sleeve rollers move in the same direction and are respectively arranged in parallel with the long rollers in the same horizontal plane.

[0017] Through the above technical scheme, the present application performs roller pressing processing through two sleeves combined with a mold of a columnar structure of foam packaging materials. On the one hand, the setting of this structure can effectively ensure the operation of different sizes of foam packaging materials, which is convenient for the actual generation and meets the needs of foam packaging materials of different sizes. On the other hand, the present application performs roller pressing processing through the sleeve setting, and directly rolls the foam material onto the mold surface, thereby facilitating actual generation and packaging and improving work efficiency. At the same time, the design of the roller press significantly improves the uniformity and stability of the prepared foam packaging material.

[0018] Preferably, the roller assembly further comprises:

[0019] A roller slide rail is arranged along the length direction of the frame body, and the two rollers are arranged on the roller slide rail so that the rollers can move along the length direction.

[0020] Through the above technical solution, the present application facilitates the rolling processing of foam packaging materials of different sizes by setting a set of roller slides.

[0021] Preferably, the set of rollers comprises:

[0022] A sleeve roller, wherein the sleeve roller is formed as a cylindrical metal piece and can move circumferentially along its axial direction;

[0023] An annular airbag, which is arranged at the end of the roller and is arranged in an annular shape along the outer circumference of the roller;

[0024] An air pump is arranged on a side of the frame body close to the roller and can inflate the annular airbag through an air pipe to inflate the annular airbag.

[0025] Through the above technical scheme, the present application makes it easy to disassemble and assemble the mold of the foam packaging material during actual use through the design of the annular airbag and the air pump. Through the expansion treatment of the annular airbag, it can ensure that the mold of the foam packaging material has good stability, which is convenient for the subsequent roll forming of the foam packaging material.

[0026] Preferably, the long roller comprises:

[0027] A long roller drum is formed as a cylindrical metal piece and can move circumferentially along its axial direction.

[0028] Preferably, the long roller further comprises:

[0029] The long roller slide rail is arranged on the same horizontal plane as the sleeve roller slide rail and is mounted on the frame body. Two long roller slide rails are provided and are vertically spaced apart from the sleeve roller slide rail. The long roller cylinder is arranged on the long roller slide rail so that it can move along the setting direction of the long roller slide rail.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. This application uses roller forming after extrusion of materials. On the one hand, this application improves the combination performance and mixing uniformity between materials through extrusion. Secondly, the technical solution of roller forming can rely on the opposite rotation of rollers. The materials passing through the gap between rollers are subjected to shear force in the calendering direction and extrusion force perpendicular to the calendering direction to become products with fixed shapes. Due to the calendering effect, the macromolecules of the product obtain a certain orientation in the calendering direction, so that it has good and stable structural strength and mechanical properties.

[0032] 2. The present application uses two sleeves in combination with a columnar structure to perform rolling processing on the foam packaging material mold. On the one hand, the setting of this structure can effectively ensure the operation of different sizes of foam packaging materials, which is convenient for the actual generation and meets the needs of foam packaging materials of different sizes. On the other hand, the present application uses the sleeve setting to perform rolling processing, and the foam material is directly rolled on the mold surface, which is convenient for actual generation and packaging and improves work efficiency. At the same time, the design of the roller press significantly improves the uniformity and stability of the prepared foam packaging material.

[0033] 3. The present application uses the design of an annular airbag and an air pump to facilitate disassembly and assembly of the mold of the foam packaging material during actual use. The expansion treatment of the annular airbag can ensure that the mold of the foam packaging material has good stability, which is convenient for subsequent roll forming of the foam packaging material.
