Polyester foam board heating welding process and heating welding equipment

Abstract

The invention discloses a polyester foam board heating and welding process and its heating and welding equipment, which are applied in the field of polyester foam board welding. The distance between the ester foam board and the surface of the heating plate is 5~15mm, and the distance between the other polyester foam board and the surface of the heating board is 0~2mm. At this time, the two polyester foam boards are left standing for heating, and the heating time is 10~30s, when the surface of the polyester foam board reaches a certain melting state; the technical effect is: it can prevent the heating plate from adhering to part of the polyester on the polyester foam board, thereby ensuring the long-term cleanliness of the heating plate surface and improving The thermal fusion efficiency of the surface of the polyester foam board and the stability of the process maximize the welding area between each polyester foam board and eliminate voids.

Description

technical field [0001] The invention relates to the technical field of polyester foam board welding, in particular to a polyester foam board heating and welding process and heating and welding equipment. Background technique [0002] Polyester foam has a wide range of applications and has penetrated into almost all sectors of the national economy, especially in furniture, bedding, transportation, refrigeration, construction, heat insulation and other sectors. It has become one of the indispensable materials and has become a plastic material. One of the most widely used species. [0003] Since a single piece of polyester foam board is integrally formed, its compressive and bending resistance in the length direction is poor, and it is difficult to adapt to some application fields with high strength requirements. The board is melted along the large vertical plane, and then cut horizontally to form a new polyester foam board. The bending and compression resistance of this polye...

Problems solved by technology

[0003] Since a single piece of polyester foam board is integrally formed, its compressive and bending resistance in the length direction is poor, and it is difficult to adapt to some application fields with high strength requirements. The board is melted along the large vertical plane, and then cut horizontally to form a new polyester foam board. The bending and compression resistance of this polyester foam board is significantly improved in both the length direction and the width direction.

[0004] The above-mentioned existing technical solutions have the following defects: when the heating plate heat-melts two polyester foam boards, it will directly contact with the large plane of the polyester foam boards for heating, which will easily cause the polyester foam boards to be partially bonded to the heated surface. Even if the heating plate is coated with anti-adhesive material, the polyester foam board will still be partially bonded to the heating plate after a period of use, which will affect the welding quality of the polyester foam board
