Description

An oven door for a rotational molding machine

technical field

The invention relates to the field of rotomolding machine equipment, in particular to an oven door of a rotomolding machine.

Background technique

As we all know, the operation of the rotomolding machine is inseparable from the heating of the oven. The oven is generally composed of a box body and two left and right sliding doors arranged at the front of the box body. The left and right sliding doors move outward to open the box door, and the rotomolding machine moves forward. Move, extend the working arm into the box body, move the left and right sliding doors to the middle to close the box door, there is a working port at the joint of the left and right sliding doors where it contacts the rotating arm, the working port is generally square, and its size is also larger than The diameter of the swivel arm, which is convenient for swiveling of the swivel arm in the working port. However, the volume of the oven is generally large. When the door of the left and right sliding doors is opened to both sides, it takes up a lot of space. Sometimes the smaller factory buildings cannot accommodate the oven with the sliding door. Very demanding.

The technical problem to be solved by the present invention is to overcome the defects of the prior art, and propose a box door of a rotational molding machine oven, which greatly reduces the occupied space of the box door and increases the adaptability of the oven to the site.

Technical scheme of the present invention:

A box door of a rotomolding machine oven, including a box body, the front side of the box body is set as a box opening, and the mold connected to the rotating arm of the rotomolding machine extends into the box body from the front side of the box body through the box opening , the left and right ends of the top plate above the box opening are provided with brackets, and rolling gates are set up on the brackets, vertical guide grooves are provided on the left and right panels of the box body at the box opening, and the curtains of the rolling gates Inserted into the guide groove from top to bottom, the curtain is provided with an opening, the opening extends upward from the bottom edge of the curtain, the opening is in the shape of a vertical strip, the center line of the opening is in line with the rotating arm The axis lines intersect, the width of the opening is greater than the diameter of the rotating arm, and the height of the top of the opening is higher than the height of the rotating arm when the rolling shutter is closed.

Further, the rolling gate is composed of a shaft with both ends fixed on the bracket, a drive disc installed at one end of the shaft, a disc mounted on the shaft to fix the curtain, and a motor. The output shaft of the motor is connected to the drive disc through a chain .

Further, the motor is a stepper motor with remote control function.

Further, the shape of the opening is an inverted "U" shape.

Further, the manufacturing material of the curtain is stainless steel.

Further, the width of the opening is 2-4cm longer than the diameter of the rotating arm.

Further, the height of the top of the opening is 1-2 cm higher than the height of the rotating arm.

Compared with the prior art, the present invention sets the door of the oven as a rolling gate, and sets an opening on the curtain of the rolling gate, which is used to pass through the rotating arm of the rotomolding machine. The rotomolding machine moves forward and the mold on the rotating arm extends into the box, and the shutter is controlled by the remote control to lower the curtain. The rotating arm is located in the opening on the curtain, which does not affect the downward movement of the curtain until the shutter is closed. At the mouth of the box, the mold is heated inside the box. The invention has the advantages of simple structure, convenient installation and manufacture, and low manufacturing cost, which effectively solves the problems that the traditional oven door occupies a large space and takes time and effort to open and use, reduces the space requirement of the oven on the site, and improves work efficiency.
