Bus seat cushion backrest foaming production line

Abstract

The invention discloses a bus seat cushion chair back foaming production line. The invention relates to the field of bus component production, aims to solve the problem that a large amount of gas is left inside after a traditional chair back and a seat cushion are produced, and the production line is characterized by comprising a first rotating disc, a feeding mechanism is arranged on the side edge of the first rotating disc, and an exhaust mechanism for exhausting air in the chair backrest and the seat cushion is arranged at the end, away from the first rotating disc, of the feeding mechanism; the feeding mechanism comprises a feeding conveying belt connected with the first rotating disc and the exhaust mechanism. The exhaust mechanism comprises a sealing box located at the end, away fromthe first rotating disc, of the feeding conveying belt. A vacuumizing device is arranged on the side wall of the sealing box; a feeding opening is formed in the top wall of the sealing box, a sealingcover covering the feeding opening is hinged to the outer side wall of the sealing box, a guiding device for guiding the seat cushion and the chair backrest into the sealing box is arranged at the end, away from the first rotating disc, of the feeding conveying belt, and the effect of conveniently exhausting air in the chair backrest and the seat cushion is achieved.

Description

technical field [0001] The invention relates to the technical field of bus component production, in particular to a foaming production line for bus seat cushions and seat backs. Background technique [0002] The bus seat is mainly used for the rest of passengers. The existing bus seat mainly includes a metal seat frame, and the EVA material seat back and cushion are arranged on the metal frame. After the EVA material is foamed, the texture is relatively Because the metal frame will be softer, it will bring comfort to passengers during the journey. [0003] The Chinese patent of the existing application publication number CN105500587A discloses a production line for foaming EVA sheets, which includes a fixed workbench, a rotating workbench, a foaming machine, and EVA sheet baking equipment. It is circular, and the rotary table is set on the inner side of the circular fixed table, and the rotary table can rotate within 360 degrees relative to the fixed table, and multiple foa...

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: there will be a large amount of gas in the seat back and seat cushion produced by the existing EVA production line, and the gas will fill the cavity in the seat cushion and the seat back, resulting in poor texture of the seat cushion and the seat back. It is very hard. One of the existing treatment methods is to place the seat cushion in an extrusion device to discharge the air in the seat cushion. However, the back of the seat contains a metal frame, and direct extrusion will cause the metal frame in the back of the seat to be damaged. problem to be solved
