Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Example (b): the bottle blank conveying line and the heating device thereof are shown in the attached figures 1-3 and comprise an annular conveying line 1, a carrier 3, a constant temperature box 2 and a workbench 4. As shown in fig. 1, the endless conveyor line 1 is a conventional guide-rail conveyor. The carrier 3 is an existing bottle embryo clamp and is used for fixing the bottle embryo. The carrier 3 is embedded on the annular conveying line 1.

The incubator 2 is fixedly mounted on the annular conveying line 1, and a cavity (the bottom of the cavity is of an open structure) is arranged in the incubator 2, and the annular conveying line 1 penetrates through the cavity (as shown in fig. 1). The thermostat 2 is used for heating bottle blanks, and under a normal working state, the bottle blanks are transported on the carriers 3 of the annular conveying line 1 and are transported to the workbench 4 for blow molding after being heated by the thermostat 2. The working table 4 is a blow-molding station (which is also located on the ring conveyor line 1), and a blow-molding mold (not shown in the figure, and different blow-molding molds can be selected according to specific products) is fixedly installed on the working table.

Two sides of the inner wall of the cavity of the constant temperature box 2 are respectively provided with a heat radiation wall 8, and the heat radiation walls 8 are of arc structures. The surface of the heat radiation wall 8 is coated with a radiation layer.

It should be noted that the radian of the heat radiation wall 8 is selected according to the actual conditions, and the standard is to radiate heat to the body of the bottle blank as much as possible and to radiate heat to the bottle mouth at the bottom of the bottle blank as little as possible. The 8 radians of heat radiation wall of this embodiment are about 80, and bottle embryo bottom bottleneck is in the below of 8 bottom end faces of heat radiation wall, and about 3cm apart from the bottom end face of heat radiation wall 8.

A heating lamp tube 5 is further disposed in the cavity of the oven 2, as shown in fig. 2, the heating lamp tube 5 is located on the inner wall of the oven 2, and a mounting frame 6 is further disposed between the heating lamp tube 5 and the inner wall of the oven 2.

It should be noted that the heating lamp 5 is used as a heat source and must have the function of uniformly heating the bottle blank. Under normal conditions, two groups are installed, namely a left group and a right group; however, if rotatable carriers (bottle blanks are rotated at a constant speed on the carriers 3) are used on the conveyor line, the heating lamps 5 may be installed in a group on one side only.

As shown in fig. 3, mounting frame 6 is provided with a mounting surface 9 which is fixedly connected to oven 2. The mounting surface 9 is provided with a mounting groove 12 on the inner side, and the mounting groove 12 is of an arc-shaped structure and is used for mounting the heating lamp tube 5 (the heating lamp tube 5 can be directly embedded into the mounting groove 12 for fixing). In addition, a wire casing 11 is arranged on one side of the mounting groove 12, and the wire casing 11 and the mounting groove 12 are separated by a heat insulation pad. Two wiring holes 10 are arranged on the outer side wall of the wire casing 11. The wire grooves 11 are used for wiring, and the wiring holes 10 are used for circuit connection. The back that wire casing 11 is located mounting groove 12 can prevent that high temperature from causing the influence to the circuit.

The top of the incubator 2 is provided with ventilation openings 7, and the number of the ventilation openings 7 can be selected according to actual conditions (such as the length of a conveying line). An induced draft fan is arranged in the ventilation opening 7, and an output port of the induced draft fan is positioned right above the ventilation opening 7.

During heating, the heating lamp tube 5 is started, the heating lamp tube 5 continuously radiates heat, and bottle blanks passing through are heated under the action of the heat radiation wall 8. It is worth noting that at this stage, it is necessary to activate the fan (which keeps the inside of oven 2 at a suitable temperature) to remove the heat, which draws the hot air out of oven 2. Outside cold air (i.e. natural air) enters the constant temperature box from the bottom and exchanges with hot air, so that the constant temperature is kept. At the moment, the cold air directly contacts the bottle mouth at the bottom of the bottle blank, so that the bottle mouth part can be always in a lower temperature state, and the subsequent blow molding work is facilitated.
