The purpose of the utility model can be realized by the following technical proposal: the oral liquid plastic bottle preforming device is characterized by comprising a rack, two guide vane press wheels, two separating blocks and a mold, wherein the guide vane press wheels, the separating blocks and the mold are sequentially arranged on the rack, the two guide vane press wheels are symmetrically distributed on two sides of the separating blocks, the separating blocks are triangular, the mold comprises two pressing plates and a section bar positioned between the two pressing plates, a plurality of pressing heads are fixedly arranged on the two pressing plates respectively, the pressing heads are connected to the rack in a sliding mode through guide rods, the pressing heads on the two pressing plates are symmetrically distributed on two sides of the section bar, and each pressing head comprises two notches which are symmetrically distributed, have the radian of 0.5 pi, and have the diameters matched with the section bar;

the profile is driven by a longitudinal cylinder which is positioned above the rack and can drive the profile to reciprocate longitudinally, and the pressing plate is driven by a transverse cylinder which is arranged on one side of the rack and can drive the pressing plate to reciprocate transversely.

After a plastic sheet is folded in half, the plastic sheet is driven to intermittently move by a guide sheet pressing wheel, a separating block is divided into pieces, the plastic sheet passes through a die, a section bar is used as a support of an inner cavity of an oral liquid plastic bottle during preforming, the section bar is pushed by a longitudinal cylinder and can move downwards to a designated position during pressing, the section bar rises to be separated from the inner cavity of a semi-finished product after pressing is completed, demolding is realized, a plurality of semi-finished products can be formed at one time, a filling process is carried out after forming, and then a closing and sealing process is carried out.

It is difficult to see out, and this device passes through profile longitudinal movement, makes the oral liquid plastic bottle inner chamber smooth level, smooths and the flattening process to the bottle inner wall before the cooling, and the bottle outer wall carries out the flattening through the pressure head, does not cut apart between the adjacent semi-manufactured goods to going on of next process, the pressure head is for being heated the state, can soften plastic wafer.

In the oral liquid plastic bottle preforming device, two groups of air injection structures positioned between the separation block and the guide vane pinch roller are symmetrically arranged on the rack, and each air injection structure comprises a plurality of longitudinally arranged air injection nozzles.

The air injection of the air nozzle and the movement of the plastic film are kept synchronous, the air injection of the air nozzle is suspended in a pressing state, and the purpose of air injection is to preheat the sheet and avoid indentation and color difference at the bending part of the sheet in the pressing and forming process.

FIG. 1 is a schematic view of the structure of the preforming device.

In the figure, 1, a guide vane pinch roller; 2. a separation block; 3. molding; 4. a pressure head; 5. a recess; 6. an air nozzle.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, the preforming device comprises a frame, two guide sheet press wheels 1, two separating blocks 2 and a mold, wherein the guide sheet press wheels 1, the separating blocks 2 and the mold are sequentially arranged on the frame, the two guide sheet press wheels 1 are symmetrically distributed on two sides of the separating blocks 2, the separating blocks 2 are triangular, the mold comprises two pressing plates and section bars 3 positioned between the two pressing plates, a plurality of pressing heads 4 are fixedly arranged on the two pressing plates respectively, the pressing heads 4 are connected to the frame in a sliding mode through guide rods, the pressing heads 4 on the two pressing plates are symmetrically distributed on two sides of the section bars 3, and each pressing head 4 comprises two notches 5 which are symmetrically distributed, have the radian of 0.5 pi and are matched with the section bars 3 in diameter;

the section bar 3 is driven by a longitudinal cylinder which is positioned above the machine frame and can drive the section bar 3 to do longitudinal reciprocating motion, and the laminated plate is driven by a transverse cylinder which is arranged on one side of the machine frame and can drive the laminated plate to do transverse reciprocating motion.

After a plastic sheet is folded in half, the plastic sheet is driven to intermittently move by a guide sheet pressing wheel 1, a separation block 2 is subjected to separation, the plastic sheet passes through a die and is preformed, a section bar 3 serves as a support of an inner cavity of an oral liquid plastic bottle, the section bar 3 is pushed by a longitudinal cylinder and can move downwards to a designated position during pressing, the section bar rises to be separated from the inner cavity of a semi-finished product after pressing is completed, demoulding is realized, a plurality of semi-finished products can be formed at one time, a filling process is carried out after forming, and then a closing and sealing process is carried out.
