Research and development of disposable tableware equipment

The existing disposable tableware equipment generally uses a cylinder as an actuator to push the molding die to mold the disposable tableware. The molding speed is controlled by the air source pressure of the cylinder. Therefore, the disadvantages include: inconvenient and inaccurate adjustment, and the molding speed is difficult to control. The molding speed is an important factor in ensuring the molding quality of disposable tableware.

Therefore, some R&D personnel have specially developed a disposable tableware equipment that can easily and accurately control the molding speed to achieve high molding quality. The equipment includes a forming die, movable bracket, fixed bracket, motor and matching screw nut. The motor is installed on the fixed bracket, the motor output shaft is connected to the screw rod, and the nut and forming die are fixedly connected to the movable bracket. The screw uses a ball screw, and the motor uses a stepper motor or servo motor. Among them, the fixed bracket is composed of a bottom plate, a top plate, and a pillar. The bottom plate is fixed on the frame through a guide plate and a base. The servo motor is installed on the top plate. The output shaft of the servo motor is connected through a ball screw and a coupling. The shaft heads at both ends of the ball screw are supported on the bottom plate and the top plate through bearings and activities. Inside, the movable bracket is composed of a guide pillar, an upper plate and a lower pillar. The upper plate is fixedly connected to the nut, and the lower plate is fixedly connected to the forming die. The guide pillar passes through the bottom plate of the fixed bracket and is slidingly connected to the specially provided guide bush on the bottom plate. At the same time, the mold rod of the forming die passes through the guide bush provided on the guide plate. This disposable tableware equipment uses motor drive and screw nut transmission instead of a cylinder to realize the linear motion of the molding die. In order to improve control accuracy, the screw uses a ball screw, and the motor uses a servo motor or stepper motor. The molding speed of this disposable tableware equipment can not only be adjusted conveniently and accurately for better control, but also be better controlled, ensuring the molding quality of disposable tableware.
