Description

Technical Field

[0001] The present invention relates to the technical field of bottle making machines, in particular to a four-drop matrix bottle making machine. Background Art

[0002] The four-drop matrix bottle making machine adopts multiple groups (arranged in rows and columns) of independent bottle making units. Each unit can produce bottles of the same or different specifications synchronously or asynchronously, and realize efficient continuous production through coordinated control; multiple bottle making units (such as 4 groups, 6 groups, 8 groups, etc.) are arranged in rows and columns, and each unit contains complete bottle making process steps.

[0003] For example, patent application CN101913754B discloses a six-drop, four-drop linear bottle making machine and its press-blow production process. The machine comprises a frame, a preform forming mechanism, a forming die forming mechanism, and a bottle-moving mechanism. The preform forming mechanism comprises an integrated multi-cavity punching device, comprising a drive cylinder, a coupling cylinder, a punch, a piston push-pull plate, and a piston, with the piston connected to the piston push-pull plate. The machine boasts high bottle production capacity and excellent forming quality, capable of producing high-end glass bottles in a variety of specifications.

[0004] However, molten glass droplets are supplied through a material distribution mechanism and a flow pipe, the molten glass droplets are initially squeezed and shaped in a primary mold forming mechanism, and the formed forced preforms are transferred to a forming mold forming mechanism through a servo flipping mechanism and a servo bottle clamping mechanism, and blow-molded in the forced preform forming mechanism. The operation process is complicated and the bottle making efficiency needs to be further improved. The forced preforms dissipate heat during the transfer process. In order to improve the plasticity of the molten glass, secondary auxiliary heating is often required during blow molding in the forming mold forming mechanism, which increases the energy consumption of the equipment.

[0037] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0038] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein may be combined with each other.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0040] Please refer to Figure 1-7 , a four-drop matrix bottle making machine, which includes: a frame 1, a distribution mechanism 2 installed on the frame 1, a flow trough 3 and multiple groups of bottle making mechanisms 43, the multiple groups of bottle making mechanisms 43 supply molten glass droplets through the distribution mechanism 2 and the flow trough 3; the bottle making mechanism 43 includes a frame 4, a mold opening and closing drive assembly installed on the frame 4, two mold bases 5 installed on the mold opening and closing drive assembly, multiple half bottle molds 6 installed on the mold base 5, a half bottom mold 7 installed in the half bottle mold 6 for sliding up and down, a lifting drive member providing power for the up and down sliding of the half bottom mold 7 and an internal pressure blowing mechanism, the internal pressure blowing mechanism includes a multidimensional driver 8, a lifting frame 9 installed on the multidimensional driver 8, multiple blowing heads 10 installed on the lifting frame 9 and an internal support core mold 11 installed at the bottom of the lifting frame 9 and connected to the corresponding blowing heads 10. The multidimensional driver 8 is used to drive the lifting frame 9 to move in the horizontal and vertical directions, and the internal support core mold 11 is used to force the internal support and blowing shaping of the bottle blank.

[0041] The multidimensional driver 8 in this embodiment can adopt a two-dimensional driver or a three-dimensional driver, which can be appropriately selected according to the unloading position of the formed glass bottle; the multidimensional driver 8 is preferably a two-dimensional driver, and the two-dimensional driver includes a horizontal seat slidably mounted on the upper part of the frame 4, a horizontal feed cylinder fixedly mounted on the frame 4 and providing power for feeding the horizontal seat, and a vertical feed cylinder fixedly mounted on the horizontal seat, and the output end of the vertical feed cylinder is transmission-connected to the lifting frame 9; the two-dimensional driver can also adopt other drivers with equivalent two-dimensional driving effects such as a two-dimensional mechanical slide; the blowing head 10 is connected to the external air pressure control system.

[0042] In other embodiments, the two-dimensional driver may also adopt the two-dimensional driver structure disclosed in CN101887007A.

[0043] Please refer to Figure 2 or Figure 13 A half funnel 31 is installed on the upper part of the mold base 5 and is arranged corresponding to the half bottle mold 6; further, the half funnel 31 on the two half bottle molds 6 form a complete funnel after closing.

[0044] Please refer to Figure 4; The lifting drive component includes a slide rod 29 fixedly installed at the bottom of the semi-bottom mold 7 and a spring 30 sleeved on the slide rod 29. A slide hole is provided on the mold base 5, and the slide rod 29 is slidably installed in the slide hole; the lifting drive component can also adopt a telescopic cylinder or other equivalent components that can drive the semi-bottom mold 7 to slide up and down.

[0045] Please refer to Figure 2-Figure 7 as well as Figure 13 The mold opening and closing drive assembly includes a rod frame 32 slidably mounted on the frame 4, a slide 33 slidably mounted on the rod frame 32, and a synchronous, directional drive. A first mounting plate 34 and a second mounting plate 35 are fixedly mounted at each end of the rod frame 32. The two mold bases 5 are mounted on the slide 33 and the second mounting plate 35, respectively. The synchronous, directional drive includes a drive gear 36 rotatably mounted on the frame 4, two racks 37 arranged parallel to and meshing with the drive gear 36, and a first drive cylinder 38 fixedly mounted on the first mounting plate 34. The output end of the first drive cylinder 38 is fixedly connected to the slide 33, and the ends of the two racks 37 are fixedly connected to the first mounting plate 34 and the slide 33, respectively. Furthermore, the two mold bases 5 are mounted on adjacent sides of the slide 33 and the second mounting plate 35, respectively. The first drive cylinder 38 is preferably a hydraulic cylinder, and its kinetic energy is provided by an external hydraulic pump station.

[0046] The four-drop determinant bottle making machine provided by the present invention has a complete funnel formed after the two half funnels 31 are closed to each other. The complete funnel can receive the molten glass droplets flowing out of the flow trough 3, so that it can more smoothly enter the bottle mouth formed by the two half bottle molds 6 being closed; when the molten glass droplets come into contact with the bottom mold formed by the two half bottom molds 7 being closed, the spring 30 is compressed under the action of the self-gravity of the molten glass droplets, and the bottom mold moves downward to ensure that the molten glass droplets enter the upper part of the complete bottle mold and avoid the molten glass droplets from completely entering the bottom of the complete bottle mold, thereby providing a guarantee for the subsequent forced bottle blank pressing; and in the process of forced bottle blank pressing, as the inner support core mold 11 gradually penetrates into the complete bottle mold, the bottom mold moves downward synchronously , so that the molten glass droplets are gradually evenly distributed from top to bottom in the complete bottle mold, thereby improving the uniformity of the distribution of the molten glass droplets in the complete bottle mold and providing a guarantee for the subsequent blow molding; it should be noted that as the spring 30 is compressed, the pressure of the bottom mold on the molten glass droplets gradually increases, and the air pressure in the forced bottle blank needs to be increased synchronously to balance the air pressure in the glass bottle and the air pressure inside the bottom mold. When the spring 30 is fully compressed, the pressure of the bottom mold on the molten glass droplets should not be too large to ensure the thickness of the molten glass droplets between the bottom mold and the inner support core mold 11; in order to control the thickness of the molten glass droplets, the lifting drive can use a telescopic cylinder to control the descending speed of the bottom mold to prevent the bottom thickness of the subsequently formed glass bottle from failing to meet the standard.

[0047] When the output end of the first driving cylinder 38 is extended, after being transmitted by the driving gear 36 and the two racks 37, the first mounting plate 34 and the slide plate 33 move away from each other synchronously, while the slide plate 33 and the second mounting plate 35 move closer to each other, so that the two mold bases 5 move closer synchronously. Similarly, when the output end of the first driving cylinder 38 is shortened, the two mold bases 5 move away from each other synchronously, thereby realizing the synchronous movement of the two mold bases 5. When unloading the molded glass bottles, the two mold bases 5 are opened synchronously, and the glass bottles are clamped by the inner support of the inner support core mold 11 and stop between the two mold bases 5, so that the force on the glass bottles is balanced, avoiding uneven force and deformation of the glass bottles during the mold opening process, thereby improving the unloading smoothness and molding success rate of the molded glass bottles in the bottle mold; compared with the traditional clamp-type mold opening and closing mechanism, it does not require an excessively large opening operation space, and the synchronous opening of the two mold bases 5 can be achieved in a small space.

[0048] For details, please refer to Figure 4-12 The inner support core mold 11 includes a neck mold rod 12 and an inner support mold installed at the bottom of the neck mold rod 12. A pressure plug 13 that fits the inner diameter of the bottle mouth on the half bottle mold 6 is fixedly installed on the neck mold rod 12. The inner support mold includes a core rod 14, multiple sets of needle exhaust valves 15 evenly distributed on the outer wall of the core rod 14, a top plug seat 16 that slides up and down on the end of the core rod 14, and multiple inner support members 17 evenly distributed around the outer wall of the core rod 14. The inner support member 17 includes a A plurality of vertically arranged sloped seats 18, vertical rods 19, a plurality of driving blocks 20 fixedly mounted on the vertical rods 19, an arc-shaped support mold 21 and a plurality of connecting rods 22 mounted on the driving blocks 20, the arc-shaped support molds 21 on the plurality of inner support members 17 are aggregated to form an annular column, the driving block 20 is provided with a slope portion that matches the inclined slope surface of the sloped seat 18, one end of the plurality of connecting rods 22 is hinged to the top plug seat 16, and the other ends of the plurality of connecting rods 22 are respectively hinged to the plurality of corresponding vertical rods 19. Furthermore, a bottle mouth shaping protrusion protruding inward is provided at the neck of the half-bottle mold 6; the bottle mouth shaping protrusion is used to shape the bottle mouth of the formed glass bottle, and can also prevent the molten glass droplets from falling quickly into the mold cavity of the half-bottle mold 6; the neck mold rod 12 and the core rod 14 both adopt internal hollow rods; the input end of the needle exhaust valve 15 is connected to the interior of the core rod 14, and the needle exhaust valve 15 is preferably a remotely controlled solenoid valve or an online controlled electric control valve; the slope seat 18 is provided with a slide groove parallel to the upper slope surface of the slope seat 18, and the drive block 20 is provided with a slide rail slidably installed in the slide groove, so that the drive block 20 can slide stably at the slope seat 18.

[0049] Please refer to Figure 4-Figure 7 as well as Figure 14The half-bottle mold 6 is rotatably mounted on the mold base 5, wherein a rotating driving member for providing power for the rotation of the half-bottle mold 6 is installed on one of the mold bases 5, and the rotating driving member includes a half gear 26 fixedly connected to the half-bottle mold 6, a gear set 27 meshing with the half gear 26, and a drive motor 28 for providing power for the rotation of the gear set 27; further, the drive motor 28 can be one or more, and the drive motor 28 and the gear set 27 can be used to provide power for the synchronous rotation of multiple half-bottle molds 6, or multiple drive motors 28 and the gear set 27 can be used to provide power for the rotation of a single half-bottle mold 6; the outer wall of the half-bottle mold 6 is coated with a molybdenum disulfide coating or a diamond-like carbon coating to reduce the friction coefficient between the half-bottle mold 6 and the mold base 5.

[0050] Please refer to Figure 11 or Figure 12 A multi-stage telescopic rod 23 is fixedly mounted on the driving block 20, and the output end of the multi-stage telescopic rod 23 is fixedly connected to the arc-shaped support mold 21; furthermore, the multi-stage telescopic rod 23 adopts a pneumatic telescopic cylinder, and the input end of the multi-stage telescopic rod 23 is connected to the interior of the core rod 14. The air inlet end of the multi-stage telescopic rod 23 is equipped with an electric control valve to control the telescopic state of the multi-stage telescopic rod 23. For details, please refer to Figure 9 or Figure 10 as well as Figure 11 or Figure 12 The top of the arc-shaped support mold 21 is provided with a bottle shoulder support mold 24, and the bottom of the arc-shaped support mold 21 is provided with a bottle bottom support mold 25. For details, please refer to Figure 3 as well as Figure 13 A first locking hook 39 is fixedly installed on the lifting frame 9, and a second locking hook 40 and a second driving cylinder 41 that provides power for the sliding of the second locking hook 40 are slidably installed on the slide plate 33; further, the second driving cylinder 41 is preferably a pneumatic cylinder, and the pneumatic cylinder provides kinetic energy through an external air pressure system; when the inner support core mold 11 is inserted into the complete bottle mold, the output end of the second driving cylinder 41 is extended, and the second locking hook 40 and the first locking hook 39 are locked, and the multi-dimensional driver 8 does not need to provide a downward force on the inner support core mold 11. The multi-dimensional driver 8 can achieve close contact between the inner support core mold 11 and the complete bottle mold without starting during the process of drop-pressing and blowing the molten glass material into a bottle, thereby reducing the energy consumption of the equipment.

[0051] Please refer to Figure 6 and Figure 14 The mold base 5 is equipped with an electromagnet 42 arranged corresponding to the half bottle mold 6, and the half bottle mold 6 is made of magnetic material; when the two mold bases 5 are separated from each other, the electromagnet 42 is started and absorbs the half bottle mold 6 to prevent the half bottle mold 6 from detaching from the mold base 5.

[0052] The four-drop determinant bottle making machine provided by the present invention has an inner support core mold 11 inserted into the molten glass drop in the complete bottle mold. Under the action of the neck mold rod 12 and the pressure plug 13, the molten glass drop between the bottle mouth of the complete bottle mold and the neck mold rod 12 is squeezed into the shape of a glass bottle mouth, and the pressure plug 13 can block the upper part of the bottle mouth of the complete bottle mold to prevent the gas source from leaking during the glass bottle blowing process; when the glass bottle needs to be blown, the inner support mold is completely inserted into the mold cavity of the complete bottle mold, and there is a pressurized gas source outside. The liquid is injected into the core rod 14 through the blowing head 10 and the neck mold rod 12, the top plug seat 16 moves downward, the connecting rod 22 pulls the corresponding vertical rod 19 to slide downward along the axial direction of the core rod 14, and the driving block 20 slides down along the inclined slope of the slope seat 18, and the arc-shaped support mold 21 moves outward away from the center of the core rod 14. Under the external support of the arc-shaped support mold 21, a larger cavity is formed in the middle of the molten glass drop, and the molten glass drop moves closer to the inner wall of the molded bottle. Then the needle exhaust valve 15 is opened, and the gas in the cavity is exhausted. As the pressure increases, the molten glass droplets are further pushed toward the inner wall of the forming bottle mold under the action of the air pressure until the molten glass droplets come into contact with the inner wall of the complete bottle mold, thereby realizing the pressing and forming of the forced bottle blank and blowing the forced bottle blank into a formed glass bottle; through the initial inner support of the inner support mold, and then the subsequent pressure blowing, the forming of the glass bottle can be completed in a single time, which greatly improves the efficiency of the glass bottle making; and when the formed glass bottle is unloaded, each arc-shaped support mold 21 is completely gathered and moved to the forming At the mouth of the glass bottle, pressurized air is again pressed into the core rod 14, the top plug seat 16 moves downward, and the arc-shaped support mold 21 is tightly in contact with the mouth of the molded glass bottle to clamp the molded glass bottle. The molded glass bottle can be moved to the desired unloading position through the multi-dimensional driver 8. The inner support core mold 11 can be used as a "unloading clamp" and no external unloading robot is required to unload the molded glass bottle; when unloading the molded glass bottle, the inner cavity wall of the molded glass bottle can also be directly supported and clamped by the arc-shaped support mold 21.

[0053] After the two half gears 26 are closed, a complete gear is formed, and the driving motor 28 drives the complete bottle mold to rotate after being transmitted through the gear set 27; in the process of forced bottle blank production, due to the high temperature of the molten glass droplets, the molten glass droplets are in an expanded state, and the contact area between the molten glass droplets and the inner wall of the complete bottle mold is large. The friction between the molten glass droplets and the inner wall of the complete bottle mold is greater than the friction between the inner support core mold 11 and the molten glass droplets. The molten glass droplets in the complete bottle mold can rotate synchronously with the complete bottle mold, and the inner support core mold 11 can evenly support the inside of the forced bottle blank during the rotation process, so that the thickness of the forced bottle blank tends to be balanced, and the inner wall tends to be smooth, which provides a guarantee for the subsequent glass bottle blowing molding quality.

[0054] When the glass bottle is blown into shape, the connection between the two half-bottle molds 6 will cause a seam line on the outer wall of the molded glass bottle. The seam line makes the outer wall of the molded glass bottle uneven. If the seam line is too large, it will affect the aesthetics and subsequent sales of the glass bottle. The seam line can be eliminated by rotating the complete bottle mold. The temperature of the molded glass bottle decreases due to the cold air flow entering the interior and contact with the half-bottle mold 6 in a low-temperature state (the mold base 5 can also be actively cooled by an external cooling device). After the glass bottle cools down, it shrinks. At this time, the pressure between the glass bottle and the inner wall of the half-bottle mold 6 decreases, and the friction between the arc-shaped support mold 21 and the inner wall of the molded glass bottle is greater than the friction between the outer wall of the molded glass bottle and the inner wall of the complete bottle mold. The molded glass bottle is clamped in the inner support core mold 11 and is in a stationary state, while the complete bottle mold is in a rotating state. During the rotation process, the complete bottle mold further shapes the outer wall of the molded glass bottle and flattens the seam line on the outer wall of the glass bottle, thereby ensuring that the inner and outer walls of the glass bottle are smooth, further improving the quality of the molded glass bottle.

[0055] By activating the multi-stage telescopic rod 23, the arc-shaped support mold 21 can be further approached to the inner wall of the complete bottle mold, and the molten glass material droplets can be further pushed toward the inner wall of the complete bottle mold, thereby reducing the wall thickness of the forced bottle blank. The thin-walled forced bottle blank can be more easily blown under the action of air pressure, providing a guarantee for the subsequent blow molding of glass bottles. It is suitable for blow molding of glass bottles with large inner diameters and greatly improves the molding quality of large inner diameter glass bottles. In the process of the complete bottle mold driving the forced bottle blank to rotate, the multi-stage telescopic rod 23 gradually extends, which plays a positive role in the molding of the forced bottle blank, making the bottle wall thickness of the molded glass bottle more balanced and reducing the error value of the bottle wall thickness at various locations of the glass bottle.

[0056] As the arc-shaped support die 21 moves away from the core rod 14, the bottle shoulder support die 24 and the bottle bottom support die 25 move synchronously with the arc-shaped support die 21. The bottle shoulder support die 24 can shape the bottle shoulder of the forced bottle blank in a rotating state, so that the thickness of the bottle shoulder tends to be consistent at all locations. The bottle bottom support die 25 can shape the bottle bottom of the forced bottle blank in a rotating state, so that the thickness of the bottle bottom tends to be consistent at all locations, thereby further improving the quality of the formed glass bottles.

[0057] Please refer to Figure 1 as well as Figure 15 A bottle conveying assembly 44 is provided on one side of the frame 1, and a bottle clamping mechanism 45 is provided on the frame 1. A plurality of clamps 46 are provided at the lower end of the bottle clamping mechanism 45. The bottle clamping mechanism 45 is connected to a lead screw (not shown in the figure) that drives it to move back and forth in a direction perpendicular to the bottle conveying assembly 44. The clamps 46 are used to transfer the formed glass bottles to the bottle conveying assembly 44, and then the bottle conveying assembly 44 is used to convey the glass bottles to the next process and cool them during the conveying process.

[0058] The use process of the four-drop determinant bottle making machine provided by the present invention is as follows: the mold opening and closing drive assembly drives the two mold bases 5 to approach each other until the two mold bases 5 are closed, and the two half bottle molds 6 are surrounded by a complete bottle mold, and molten glass droplets are supplied to the bottle mouth of the complete bottle mold through the material distribution mechanism 2 and the flow trough 3. The molten glass droplets fall into the bottle mouth of the complete bottle mold through the funnel surrounded by the two half funnels 31, and the lifting drive member drives the half bottom mold 7 to move downward synchronously until the molten glass completely enters the bottle mouth. The multi-dimensional driver 8 drives the lifting frame 9 to move to the top of the bottle mouth and move downward, the inner support core mold 11 is inserted into the bottle mouth and blocks the bottle mouth, and the molten glass droplets in the complete bottle mold are squeezed into forced bottle blanks by the inner support core mold 11. In this process, the rotating drive The moving part drives the two half bottle molds 6 to rotate, and the multi-stage telescopic rod 23 gradually extends, and the forced bottle blank is further shaped under the action of the arc support mold 21, the bottle shoulder support mold 24 and the bottle bottom support mold 25 on the inner support core mold 11. Then the needle exhaust valve 15 is opened, and then air is blown into the forced bottle blank through the blowing head 10 and the inner support core mold 11, so that the forced bottle blank is blown into a glass bottle shape in the complete bottle mold. Then the inner support core mold 11 clamps the molded glass bottle inner support, and the rotating driving part drives the complete bottle mold to rotate to shape the outer wall of the molded glass bottle. After the shaping is completed, the opening and closing mold drive assembly drives the two mold bases 5 to separate from each other, and the molded glass bottle is located on the inner support core mold 11, and the molded glass bottle can be unloaded through the multi-dimensional driver 8.
