Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic bottle production, in particular to a linear injection blow filling all-in-one machine. BACKGROUND

[0002] Plastic bottles are a kind of common containers with very large demand, and are widely used in many fields, such as food and beverage, medical containers, medicine containers, seasoning containers, etc. The production process of plastic bottles has two-step method (commonly used in the early stage of industry development, i.e. first making bottles, then storing the made bottles for later use as needed, the bottle making and use are separated, i.e. two-step method) and one-step method (the bottle making and use are on the same production line).

[0003] In recent years, the one-step method has been increasingly recognized by the market. For example, a Chinese patent with application number CN202210193687.X discloses a linear injection blow filling all-in-one plastic bottle packaging equipment. In the patent (CN202210193687.X), as shown in the attached Figure 1 , a bottle receiving mechanism composed of a transition slide rail 105, a transition mold 106, a lifting power device 107, and a horizontal power device 108 is provided, and a bottle taking mechanism not shown in the attached Figure 1 is provided. During operation, the bottle receiving mechanism is started to move the transition mold 106 horizontally between the blank mold assembly 101 and the half mold 103. When the half mold 103 rises to a certain height and the mold is opened, the bottle preform in the half mold 103 automatically falls into the corresponding transition mold 106 below, and then the transition mold 106 drives the bottle preform to return horizontally and exit to the center axis position of the whole machine. At this time, the bottle taking mechanism first descends to clamp the bottle preform, then moves upward to a certain height and stops to take the bottle preform out of the transition mold 106. Finally, the transfer mechanism moves horizontally to clamp the bottle preform on the bottle taking mechanism and then moves vertically to the next process.

[0004] In the patent, since the transition mold 106 cannot be opened, the bottle taking mechanism is required to take the bottle preform out of the transition mold 106 upward. The addition of the bottle taking mechanism not only makes the whole device complex and increases the manufacturing cost, but also makes the bottle preform exposed to the air for a long time during the operation process of first descending to take the bottle, then moving upward to a certain height and stopping, which results in more heat loss. Additional heating is required before the subsequent pre-blowing or formal blowing, which not only consumes energy and increases cost, but also seriously affects the work efficiency.

[0005] In the second aspect, due to the structure of the bottle receiving mechanism and the bottle taking mechanism, the device operation is complex and has many steps, which not only leads to the difficulty in seamless connection between the injection molding of the bottle preform mold and the preform taking step, and a long idle time, but also makes the subsequent process unable to be connected for continuous and efficient production of multiple batches, and makes the existing injection molding module 100 intermittent injection molding, which cannot realize continuous injection molding to meet the efficient production.

[0006] Thirdly, the bottle receiving mechanism has lateral reciprocating movement along the width direction, so the transfer mechanism can only be arranged on the lateral outward side of the bottle receiving mechanism to avoid interference, that is, the transfer mechanism can only transfer the bottle preforms after clamping the bottle preforms on one side of the bottle preforms, and cannot be arranged on the two opposite sides of the bottle preforms to transfer the bottle preforms after clamping the bottle preforms; the position where the bottle receiving mechanism and the transfer mechanism transfer the bottle preforms is the central axis position of the whole device, and the subsequent heat preservation device, pre-blowing device, bottle blowing device, filling device, sealing device and output device are arranged along the central axis (the injection molding module 100 is located on one side of the central axis), so when designing, to avoid the interference between the transfer mechanism and the bottle receiving mechanism, the transfer mechanism has two actions of lateral and longitudinal directions, and each action is as follows: first, the transfer mechanism approaches the central axis laterally to take the bottle preforms, then moves longitudinally to the next working position, then exits laterally, and finally moves longitudinally to return to the initial position to wait, and the movement route of the transfer mechanism is a "mouth" type, so the transfer mechanism has a complex structure, a complex action process, a high manufacturing cost and a low working efficiency.

[0060] Optionally, as Figure 6 And Figure 5As shown, the straight line conveying device 40 comprises the heat preservation mold stripping device 42 arranged reciprocatingly along the central axis 110, and the heat preservation mold stripping device 42 is arranged transversely opening and closing along the central axis 110 for clamping and heat preservation of the bottle preform row. In operation, the upper mold of the bottle preform forming mold 20 drives the bottle preform row to move upward, and the heat preservation mold stripping device 42 slides along the central axis 110 to the lower side of the upper mold, at this time, the heat preservation mold stripping device 42 is slightly opened or not clamped along the transverse width direction, the upper mold is opened, and all the bottle preforms in the bottle preform row are freely dropped to the heat preservation mold stripping device 42 below, after all the bottle preforms enter the heat preservation mold stripping device 42, the heat preservation mold stripping device 42 clamps the bottle preform row and heat preserves the bottle preforms, and finally the heat preservation mold stripping device 42 drives the bottle preform row to slide along the central axis 110 to the transfer station, and after the heat preservation mold stripping device 42 moves to the position at the transfer station, it is opened to expose the bottle preform row, and the bottle conveying device at the transfer station clamps the bottle preform row to move longitudinally to the next station.
