Description

Rotating disk type container forming system, container forming method and product thereof

Technical Field

The invention relates to a container forming system, in particular to a rotating disc type container forming system capable of manufacturing a plastic container product with the texture similar to glass. The invention further comprises a rotating disc type container forming method and a product thereof, wherein the container forming system can be used for manufacturing a plastic container product with the texture similar to glass.

Background

Hollow containers used for holding articles in the past, such as cosmetic bottles, care bottles, perfume bottles, and medicine bottles … …, are mostly made of glass materials, so that the walls of the glass containers have a certain thickness and weight feeling, but the glass containers have a significant disadvantage of being easily broken.

Based on this disadvantage of the known glass containers, the associated practitioner is pursuing the need for a container that is not fragile, and that reduces the manufacturing costs, and therefore polymeric materials, such as plastics, are widely used for the production of containers. The commonly known plastic containers are roughly divided into two types, one of which is blow molding and the other is injection molding.

The bottle blowing molding is that a high molecular material is made into at least one hollow bottle blank by an injection molding mode through at least one bottle blank mold of an injection device, then each bottle blank with high temperature is placed into a bottle blowing mold of another extension bottle blowing device, each bottle blank softened by heat is expanded and attached to the inner wall of the bottle blowing mold through an air filling bottle blowing mode, and finally at least one molded plastic container is ejected through an ejection mechanism, thus completing the molding step of the bottle blowing molding. The bottle blow molded plastic container has the advantages that the plastic container is not easy to break, the shape below the bottle opening is changed greatly, and the thick feeling similar to glass cannot be formed due to the thin wall of the bottle.

The injection molding is to make a polymer material into at least one plastic container by an injection molding method through at least one bottle mold of an injection device, and the at least one plastic container is ejected by an ejection mechanism to complete the molding step of the injection molding. The injection molding plastic container has the advantages that the plastic container is not easy to break, and the plastic container with thicker bottle wall and similar glass texture can be manufactured; however, the internal volume of the plastic container is defined by a slide which can axially extend and retract within the bottle mold, so that a receiving chamber with a predetermined volume is formed within the plastic container.

Therefore, how to manufacture a plastic container with a texture similar to glass without increasing the height of the plastic container or increasing the size of the bottle body when the internal volume of the plastic container is changed is a common problem for related practitioners.

Detailed Description

As shown in fig. 1 to 12, basically, the turntable type container forming system of the present invention is composed of a lifting and rotating mechanism 1, a first injection mechanism 2, an extended bottle blowing mechanism 3, a second injection mechanism 4, and an ejection mechanism 5.

Referring to fig. 1 to 3, the lifting and rotating mechanism 1 includes a lifting base 11 and a rotating disc 12 pivoted therein, the lifting base 11 is driven by a lifting driving device 13, such as a hydraulic cylinder or a pneumatic cylinder, to be lifted and lowered longitudinally on a plurality of supports 141 fixed on a machine 14, so as to drive the rotating disc 12 to move longitudinally synchronously. These are well known techniques and will not be described in detail herein. A transmission device 15 is disposed above the rotary table 12, for example, a servo motor drives the rotary table to rotate, a first station, a second station, a third station and a fourth station are respectively formed at positions of the rotary table 12 corresponding to the first ejection mechanism 2, the extended bottle blowing mechanism 3, the second ejection mechanism 4 and the ejection mechanism 5, and four bottle mouth seats 121 are disposed at positions of the bottom of the rotary table 12 corresponding to the first to fourth stations, so that when the rotary table 12 rotates, the four bottle mouth seats 121 respectively circulate and position among the first station, the second station, the third station and the fourth station in sequence.

The bottle mouth seats 121 are of a known structure, each bottle mouth seat 121 has one or more bottle mouth dies 122, and each bottle mouth seat 121 is divided into two halves, that is, each bottle mouth seat 121 is formed by combining two split mold clamping sheets 121a (shown in fig. 11 and 12), and the two are pressed against each other by at least one elastic device, such as a pressing spring (not shown due to the projection angle relationship), and the adjacent surface of the top surface of the pair of mold clamping sheets 121a is provided with a pair of inclined surfaces 121b which are inclined inwards and form a V-shaped guide groove 121c when sealed.

The first injection mechanism 2 is located at the first station and includes at least one blank mold 21 and at least one core mold 22, which is located above the lifting base 11 and has the same number as the at least one blank mold 21, the at least one blank mold 21 is fixed on the machine table 14 and located below the turntable 21, and the at least one core mold 22 is connected to a first telescopic driving device 23, such as the bottom of a pneumatic cylinder. If the injection operation of at least one bottle blank a is to be performed, the lifting driving device 13 drives the lifting seat 11, the rotating disc 12 and the at least one bottle neck mold 122 of the bottle mouth seat 121 therebelow to descend, so that the at least one bottle neck mold 122 is inserted into the at least one bottle blank mold cavity 211 correspondingly formed in the bottle blank mold 21. Then, the first telescopic driving device 23 is activated to make each core mold 22 pass through the corresponding bottle neck mold 122 and extend into the corresponding bottle blank mold cavity 211 of the bottle blank mold 21 to form a mold closing state. Finally, a discharging tube 25 of a first injection machine 24 injects the molten plastic into the bottle blank mold 21 to perform an injection operation of at least one bottle blank a, after the mold opening mold 122 is opened, the first telescopic driving device 23 drives the core mold 22 to ascend, and then the lifting and rotating mechanism 1 drives the lifting seat 11 to ascend, so that the at least one bottle blank a leaves the bottle blank mold 21 and is clamped by the at least one bottle opening mold 122 of the bottle opening seat 121 (as shown in fig. 4), so that the at least one bottle blank a is located at the first station.

As shown in fig. 5, when the bottle opening seat 121 and the at least one bottle preform a clamped by the at least one bottle opening die 122 thereof rotate to the second station, i.e. the position of the extended bottle blowing mechanism 3, via the turntable 12.

As shown in fig. 6, the extended bottle blowing mechanism 3 includes at least one bottle blowing mold 31 fixed on the machine 14, and at least one air blowing extension rod 32 disposed above the lifting base 11 and having the same number as the at least one bottle blowing mold 31. The bottle blowing mold 31 receives the at least one bottle preform a transferred from the first station, and the top of the bottle blowing mold is used for inserting the bottle opening molds 122. If the bottle blowing operation of the at least one bottle preform a is to be performed, the lifting driving device 13 drives the lifting base 11, the turntable 12, the at least one bottle neck mold 122 of the bottle neck base 121 and the at least one bottle preform a to descend together, so that the at least one bottle preform a is inserted into the at least one bottle blowing mold cavity 311 correspondingly formed in the bottle blowing mold 31 in the mold opening state, and then is closed by at least one first opening and closing driving device 33, such as a pair of oil hydraulic cylinders, at two sides of the bottle blowing mold 31. At this time, each of the air-blowing extension rods 32 descends by the action of a second telescopic driving device 34, such as a pneumatic cylinder, and passes through and closes each of the bottle mouth molds 122 of the bottle mouth seat 121, so that each of the air-blowing extension rods 32 extends into the corresponding bottle preform a for performing air-blowing expansion operation, and each bottle preform a is expanded and attached to the inner wall of the corresponding bottle-blowing mold cavity 311, thereby forming at least one container semi-finished product B as shown in fig. 7.

Referring to fig. 7, after the at least one container semi-finished product B is cooled and solidified, the at least one blowing extension rod 32 retracts, and the bottle blowing mold 31 is opened by the at least one first opening/closing driving device 33. At this time, the lifting and rotating mechanism 1 drives the bottle mouth seat 121 and the at least one container semi-finished product B clamped by the at least one bottle mouth mold 122 to ascend, and then rotates to the third station shown in fig. 8, i.e. the position of the second injection mechanism 4, through the turntable 12.

As shown in fig. 9, the second injection mechanism 4 includes at least one covering mold 41 fixed on the machine 14 and at least one extending assembly 42 disposed above the lifting base 11 and having the same number as the at least one covering mold 41. The cover mold 41 receives the at least one container semi-finished product B transferred from the second station therein, and the top thereof is used for inserting each bottle neck mold 122. If the at least one container semi-finished product B is to be coated and ejected, the lifting driving device 13 drives the lifting base 11, the rotating plate 12, the at least one neck mold 122 of the neck base 121 and the at least one container semi-finished product B to descend together, so that the at least one container semi-finished product B is inserted into the at least one coating mold cavity 411 correspondingly formed in the coating mold 41 in the mold opening state, and passes through at least one second opening and closing driving device (not shown in the perspective view, the at least one second opening and closing driving device is equivalent to the at least one first opening and closing driving device 33 shown in fig. 9) on both sides of the coating mold 41, for example, a pair of hydraulic cylinders is used for mold closing.

At this time, each pressure maintaining extension assembly 42 descends by the action of a third telescopic driving device 44, such as a pneumatic cylinder, and passes through and closes each bottle neck mold 122 of the bottle neck seat 121, so that an air inlet pipe 421 of the pressure maintaining extension assembly 42 extends into the corresponding container semi-finished product B for blowing, and the excess air in each container semi-finished product B is exhausted from an air exhaust pipe 422 of the pressure maintaining extension assembly 42, so that the in-bottle pressure in the container semi-finished product B maintains a default value, thereby forming a pressure maintaining blowing and exhaust cooling effect.

Then, a molten plastic is injected into the coating mold 41 by an injection/discharge pipe 46 of a second injection machine 45 at a predetermined injection pressure, so as to perform a plastic thickening operation on the outer wall of each of the vessel semi-finished products B to form a vessel finished product C. In the coating injection operation, the pressure in the bottle is greater than the injection pressure, so that the semi-finished product B of the container is not contracted and deformed, the change of the inner volume of the finished product C of the container is avoided, and the finished product C of the container with the texture similar to glass can be manufactured.

After the at least one container product C is cooled and solidified, the at least one stretching assembly 42 is retracted, and the covering mold 41 is opened by the at least one second opening/closing driving device. At this time, the lifting and rotating mechanism 1 drives the bottle mouth seat 121 and the at least one container finished product C clamped by the at least one bottle mouth mold 122 to ascend, and then rotates to the fourth station shown in fig. 10, that is, the position of the ejection mechanism 5, through the turntable 12.

Referring to fig. 10 to 12, the ejection mechanism 5 is mounted on the lifting base 11 and has a bottle releasing device 51 capable of vertically lifting, the bottle releasing device 51 includes at least one ejecting blade 511 with a bottom having a tapered thickness and formed in a flat shape, such as a screwdriver shape, and the at least one ejecting blade 511 is driven by a fourth telescopic driving device 52 to lift. In one embodiment, the at least one ejecting blade 511 is mounted on a bottom surface of a cross bar 512, and the cross bar 512 is driven by the fourth driving device 52 to move up and down.

When the at least one container product C is transferred to the fourth station, the fourth retractable driving device 52 on the lifting base 11 drives the at least one ejecting blade 511 to enter the guiding slot 121C on the top surface of the bottle mouth base 121, so as to expand and laterally displace the pair of mold clamping sheets 121a to separate each bottle mouth mold 122, so that the at least one container product C falls, and then the at least one ejecting blade 511 retracts along with the fourth retractable driving device 52, so that the at least one container product C falling off can be conveyed out of the machine 14 via a conventional conveying belt (not shown).

After the at least one container product C is conveyed by the conveyor belt, the lifting seat 11 is lifted and rotated so as to return to the first station from the fourth station, and the remaining three finish seats 121 are respectively rotated to the next station in sequence, for example, the finish mold 122 of the original first station clamps another at least one bottle blank a and transfers it to the second station, the finish mold 122 of the original second station clamps another at least one container semi-product B and transfers it to the third station, and the finish mold 122 of the original third station clamps another at least one container product C and transfers it to the fourth station, so as to repeat the continuous operations of the bottle blank ejection, the extended bottle blowing, the cladding ejection and product ejection.
