Hot-melting edge sealing fixture

Abstract

The invention relates to a hot-melting edge sealing fixture which comprises a fixture seat and a workbench, wherein the workbench is provided with a film fixing groove, a film cavity fixing block, a side edge fold-down plate, a front flanged plate, a push-up folded plate, a side edge fold-up frame and a hot melting device; and the workbench is further provided with a first cylinder, a second cylinder, a third cylinder, a screw rod sliding mechanism, a servo motor, a four cylinder a fifth cylinder. The hot-melting edge sealing fixture adopts the edge sealing mode that the margins of a first edge and a third edge and the margins of a second edge and a fourth edge are overlapped, the overlapped parts are melted into one in a hot melting mode, thereby achieving the purpose of edge sealing. Inthe hot melting mode, the sealing edge belongs to face-face contact, has a good mechanical property and is not easy to break. The edge sealing fixture has the advantages of high degree of automation,high processing efficiency and low processing cost.

Description

Technical field [0001] The invention relates to the field of film processing, in particular to a hot-melt edge sealing jig. Background technique [0002] Such as figure 1 The film shown needs to seal the first side A1 and the third side B1, and the second side A2 and the fourth side B2. The existing method is as follows figure 2 As shown, fold A in half along the middle line, roughly coincide with B, align the first side A1 with the third side B1, and align the second side A2 with B2, and then use a hot melt knife to cut the part near the edge (along the dotted line) Cut off, the first side A1 and the third side B1, the second side A2 and the fourth side B2 of the film will be melted together at the cut part under the action of the hot melt knife to form an edge seal. Although this method has achieved the purpose of edge sealing to a certain extent, it is easy to break at the edge of the product during actual use, that is to say, the first side A1 and the third side B1, and the ...

Problems solved by technology

Although this method achieves the purpose of edge banding to a certain extent, the product is easy to break at the edge banding during actual use, that is to say, the first side A1 and the third side B1, the second side A2 In the process of edge sealing with the fourth side B2, the connection is a wire connection, and the contact area is extremely small, and it will be broken with a little force. Therefore, a new edge sealing method needs to be designed to overcome the shortcoming of easy disconnection
