Problems solved by technology

The degree of mechanization of this method is not high, basically still rely on manual production, the production efficiency is low, the continuity is poor, the process and process conditions are easy to master, resulting in the disadvantages of high production intensity, high production cost and unstable product quality
In addition, the constant temperature process needs a special constant temperature furnace to achieve, the energy utilization rate is low, and the furnace body is constantly opened and the mold is moved, which also causes a lot of waste of energy

Embodiment Construction

[0023] As shown in Figures 1 to 4, the main body of the equipment of the one-time forming production line for seat cushions and back cushions of the present invention is a turntable mechanism. The turntable mechanism is composed of a turntable 1 and a turntable drive device. The speed reducer 3 connected by transmission on the output shaft constitutes, and the sprocket assembled on the output shaft of the speed reducer 3 cooperates with the ring gear formed by the fixed circle chain at the bottom of the turntable 1 . There is a one-time forming mold 4 with a circle of seat cushion and back cushion installed around the turntable 1. The one-time forming mold 4 is a vacuum-absorbing one-time forming mold for cold plastic high-resilience foaming materials and fabrics. The mold 4 is equipped with a vacuum for fabrics. structure and the liquid circulation heat exchange mechanism 9 for the foaming material, a liquid temperature control circulation device and a vacuum pumping device 6 ...

Abstract

The chair cushion and back pad one time forming production line equipment comprises a rotary table that is made of the rotary plate and its drive mechanism, a ring of cushion and back pad one time forming mold around the rotary plate. With this reciprocating control and running, it can greatly improve production efficiency, reducing labor intensity. With standardized and consistent process and craft conditions, it effectively ensures and improves the product quality. Using temperature and vacuum drawing control on the rotary plate, it can effectively improve the energy utilization, reduce energy waste.

Description

technical field [0001] The invention relates to a production equipment for seat cushions and back cushions, in particular to a one-time forming production line equipment capable of continuous and efficient operation. Background technique [0002] At present, the production of seat cushions and back cushions is still carried out in a manual and semi-mechanized manner. The process is to prepare a set of molding molds first, and a vacuum chamber is installed under the molding cavity in the mold. There are capillary holes for air extraction, and the upper opening of the mold cavity is equipped with a mold cover. During production, first heat the airtight and soft fabric (such as various soft leather) of the heated seat cushion or back cushion to a certain degree, then stretch it out and place it on the mold mouth, and then vacuum it so that the fabric is sucked tightly On the inner wall of the mold cavity, preform the contours of the face and side of various types of seat cushi...
