Abstract

This invention relates to a processing method for trimming thick foam tape, comprising the following steps: S1: Unwinding: The thick foam tape is unwound on an unwinding machine; S2: Feeding: The foam tape with a protective film is unwound and conveyed to the first workstation; S3: Forming: At the first workstation, a release film is installed, two double-sided adhesive strips are applied to both sides of the product, and then the release film is applied; trimming is performed at the second workstation; S4: Rewinding: The formed thick foam tape is wound into the third workstation via a traction wheel. Compared with the prior art, this invention improves material displacement and steps (uneven trimming) by fixing the release film suspended on both sides with double-sided adhesive.

Description

Technical Field

[0001] This invention relates to the field of thick foam processing technology, and in particular to a processing method for trimming thick foam strips. Background Technology

[0002] Foam is a material made by foaming plastic particles. Foam types include PU foam, antistatic foam, conductive foam, EPE, antistatic EPE, CR, EVA, crosslinked PE, SBR, EPDM, etc.

[0003] Foam has a series of characteristics such as elasticity, light weight, quick pressure-sensitive fixation, ease of use, flexible bending, ultra-thin size, and reliable performance.

[0004] Trimming the material strip is a major challenge for foam products because the thick foam strips are left unsupported on both sides after lamination. Trimming can result in uneven edges and discrepancies between the product and the strip edge dimensions. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects of the existing technology and provide a processing method for trimming thick foam material strips. By fixing the release film suspended on both sides with double-sided adhesive, abnormalities such as material displacement and steps (uneven trimming) can be improved.

[0006] This invention provides a processing method for trimming thick foam material, comprising the following steps:

[0007] S1: Unwinding: The thick foam strip is installed on an unwinding machine for unwinding;

[0008] S2: Feeding: Discharge the foam material strip with protective film and convey it to the first workstation;

[0009] S3: Molding: At the first workstation, the release film is installed, two strips of double-sided tape are applied to both sides of the product, and then the release film is applied; at the second workstation, the edge trimming process is carried out.

[0010] S4: Winding: The formed thick foam strip enters the third workstation for winding via the traction wheel.

[0011] Furthermore, in S2, the foam strip with a protective film is fed out by a servo motor.

[0012] Furthermore, in S3, the molds used by the first and second workstations have two mold clamps to assist in product molding.

[0013] Furthermore, the mold clamps of the molds used in the first and second workstations are adjusted using screws to accommodate thick foam strips of different widths.

[0014] Furthermore, the width of the thick foam strip is 30mm-50mm.

[0015] Furthermore, the diameter of the thick foam strip roll is 200Mmin-300Mmin.

[0016] Furthermore, the inner wall of the mold during processing is provided with several cooling holes, with a 5cm interval between adjacent cooling holes and a diameter of 0.5mm, to cool the mold.

[0017] Furthermore, in S3, two 5mm double-sided adhesive strips are applied to both sides of the product, followed by a release film.

[0018] Furthermore, in S3, the product edges are trimmed using an edge trimmer or milling machine.

[0019] Furthermore, in S3, the release film suspended on both sides is fixed by double-sided adhesive.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] In this invention, the release film is fixed together on both sides by double-sided adhesive and a protective film, ensuring dimensional stability and fully meeting customer precision requirements. The double-sided adhesive also helps to fix the release film, which is suspended on both sides, improving issues such as material displacement and uneven edges (steps). Attached Figure Description
