Description

Technical Field

[0001] This invention relates to the technical field of glass bottle manufacturing, and more particularly to a small-mouth blow molding device and method for energy-saving glass bottles. Background Technology

[0002] The glass blowing equipment in the glass bottle production process is mainly used to produce glass containers of various shapes and sizes, such as bottles and jars. This process is one of the key links in glass bottle production. It is usually mainly composed of pressing and blowing. The pressing equipment combines two processes, forming glass bottles by pressing and blowing bubbles. The press-blowing process is a method of pressing molten glass into a mold and expanding it with air pressure. In this process, the raw material is heated to a high temperature and then pressed and shaped through a specific mold to form the initial shape of the bottle.

[0003] While existing glass blowing processes can effectively produce glass bottles using high-pressure gas, they still have the following problems: When molten glass is blown into the initial shape of a bottle, the molten glass itself is fluid, and due to gravity, the glass solution will accumulate towards the bottom of the bottle. This sag phenomenon will cause the glass at the bottom of the bottle to be relatively thick, while the bottle mouth and side walls may be thinner, resulting in uneven glass bottle thickness. At the same time, during the blowing process, the airflow expands the glass bottle through the blowing device. If the angle at which the high-pressure airflow enters the glass bottle is off, the airflow distribution inside the glass bottle will be uneven, which may also lead to uneven bottle thickness. Furthermore, under the influence of gravity and uneven airflow, the glass bottle needs to be blown under high pressure for a longer time, which not only affects the production efficiency of glass bottles but also greatly increases energy consumption and production costs during the production process. Summary of the Invention

[0004] In view of the problem that the thickness of glass bottles may be uneven due to gravity and airflow angle deviation during the blowing process of molten glass in the existing technology, a small-mouth pressure blowing device and method for energy-saving glass bottles is proposed.

[0005] This application provides a small-mouth pressure blowing device and method for energy-saving glass bottles. The purpose is to: by setting up a rotatable horizontal mold cylinder and a transfer cylinder, when the transfer cylinder injects high-pressure gas into the molten glass through the pressure blowing groove, it will drive the molten glass to rotate continuously at high speed. The centrifugal force generated by the high-speed rotation makes the bottle body of the molten glass in a uniform state and with consistent thickness during the blowing process. Under the action of centrifugal force, it will also assist the internal molten glass to move outward, effectively reducing the blowing time, improving the production efficiency of glass bottles, and reducing energy consumption in the production process.

[0006] The technical solution of the present invention is: a blow molding device for small mouth of energy-saving glass bottles, including a mounting base plate and a horizontal blowing unit disposed on the mounting base plate, wherein the horizontal blowing unit includes a mold-changing component and a blow molding component disposed on the mounting base plate;

[0007] The mold-changing component includes sliding grooves on both sides of the mounting base plate, sliding rods slidably disposed in the two sliding grooves, sliding support plates respectively disposed on the side walls of the two sliding rods, a bearing plate disposed between the two sliding support plates, two rotating seats disposed on both sides of the upper end of the bearing plate, rotating rods disposed on the two rotating seats, opening and closing arc rods disposed on the rotating rods, a closing cylinder disposed at one end of the opening and closing arc rods, an embedding groove disposed inside the closing cylinder, a mold cylinder disposed in the embedding groove, and a mold groove disposed inside the mold cylinder.

[0008] A limit unlocking component is installed between the mold cylinder and the closed cylinder. A support base is installed on the upper end of the mounting base plate. A load-bearing plate is set on the side wall of the support base. An interlocking plate is set on the side wall of the load-bearing plate. A servo rod is set on the load-bearing plate. A push rod is set on the side wall of the interlocking plate. One end of the push rod is fixedly connected to the telescopic end of the servo rod.

[0009] Furthermore, the limiting and unlocking assembly includes limiting grooves formed on the two closed cylinders, an installation groove formed on the mold cylinder, a positioning plate set on the inner wall of the installation groove, a return spring set on the positioning plate, a limiting block set on the return spring, the upper end of the limiting block being located in the limiting groove, a stop rod set at the lower end of the limiting block, a linkage plate set at the lower end of the stop rod, and a mating element installed on the mold cylinder.

[0010] Furthermore, the mating element includes a square groove formed inside the mold cylinder, a transmission block slidably disposed inside the square groove, and a synchronizing rod disposed at the lower end of the transmission block, the lower end of the synchronizing rod being fixedly connected to the upper end of the linkage plate.

[0011] Furthermore, the rotary blowing component includes a back plate disposed on the upper end of the mounting base plate, a drive box disposed on the side wall of the back plate, a drive motor disposed in the drive box, a transfer cylinder disposed on the side wall of the drive box, a pressure blowing groove opened at the axis of the transfer cylinder, and a connecting component installed between the transfer cylinder and the transmission block.

[0012] Furthermore, the connecting assembly includes a sealing ring disposed on the side end wall of the transfer cylinder and a connecting sleeve disposed on the side end wall of the transfer cylinder, wherein the shape and size of the end face of the inner wall of the connecting sleeve are equal to the shape and size of the end face of the transmission block.

[0013] Furthermore, a telescopic rod is fixedly installed at the upper end of the sliding support plate, and a hinge rod is installed at the end of the opening and closing arc rod away from the closing cylinder. The telescopic end of the telescopic rod is fixedly connected to the hinge rod.

[0014] Furthermore, a method for applying a small-mouth press-blown glass bottle to energy-saving glass includes the following steps:

[0015] Raw material melting: Quartz sand, soda ash, limestone and other raw materials are melted at high temperature to form a uniform glass melt;

[0016] Material feeding: Molten glass is cut into quantitative droplets by a feeding machine and dripped into the primary mold;

[0017] Initial pressing: The punch presses downwards to form the initial shape of the bottle mouth and body;

[0018] Transfer: The semi-finished product formed by initial pressing is transferred from the initial mold to the mold cylinder through the transfer cylinder;

[0019] Blow molding: High-pressure gas is injected into the semi-finished product through the blow molding trough, and the mold cylinder is driven to rotate synchronously by the high-speed rotating transfer cylinder, so that the glass expands evenly and fits the inner wall of the mold groove to form the final bottle shape.

[0020] Annealing: The formed glass bottle is placed in an annealing furnace for annealing;

[0021] Inspection and Packaging: Defective products are removed through appearance inspection and thickness testing, and qualified products are packaged.

[0022] Furthermore, during the annealing process of the glass bottle, the temperature inside the annealing furnace is 500-600 degrees Celsius, and the temperature is slowly reduced to eliminate internal stress in the glass bottle and prevent cracking.

[0023] The beneficial effects of this invention are:

[0024] 1. By setting up a rotatable mold cylinder and a transfer cylinder, when the transfer cylinder injects high-pressure gas into the molten glass, it will drive the mold cylinder to rotate synchronously at high speed. The high-speed rotating mold cylinder can make the molten glass more evenly distributed through centrifugal force. Furthermore, by setting the mold cylinder horizontally, it can effectively avoid the situation where the thickness between the bottom and the body of the bottle is uneven due to gravity. The horizontal setting of the mold cylinder and the centrifugal force generated by high-speed rotation work together to effectively avoid the situation where the thickness of the bottle body is uneven.

[0025] 2. By setting a limit unlocking component, when the mold cylinder is in a non-working state, the limit block limits the mold cylinder, so that the mold cylinder will not rotate relative to the closed cylinder. When the mold cylinder is in a working state and the transfer cylinder is pressed against the side end of the mold cylinder, the limit block will not limit the mold cylinder, and the mold cylinder can rotate at high speed with the transfer cylinder. This ensures that when the mold cylinder is in a non-working state, the mold cylinder will not rotate relative to the closed cylinder and will not be displaced, thus affecting the merging of the two mold cylinders later.

[0026] 3. By setting up a mold cylinder that can rotate at high speed, when high-pressure gas is injected into the molten glass, centrifugal force assists the high-pressure gas to promote the molten glass to diffuse outward and adhere tightly to the inner wall of the mold groove. This ensures that the molten glass is evenly distributed and accelerates the forming speed of the molten glass, effectively reducing the injection time of high-pressure gas and greatly reducing energy consumption in the glass bottle preparation process. Even if the angle of the gas entering the molten glass deviates during high-speed rotation, it will not cause uneven glass bottle forming, further improving the uniformity of the glass bottle preparation process.

[0040] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] Example 1, referring to Figures 1-7 as well as Figure 11 The first embodiment of the present invention provides a small-mouth blow molding device for energy-saving glass bottles, including a mounting base plate 1 and a horizontal blowing unit mounted on the mounting base plate 1. The horizontal blowing unit includes a mold-changing component and a blowing component mounted on the mounting base plate 1.

[0042] The mold-changing component includes sliding grooves 2 on both sides of the mounting base plate 1, sliding rods 3 slidably installed in the two sliding grooves 2, sliding support plates 4 fixedly installed on the side walls of the two sliding rods 3 respectively, bearing plate 5 fixedly installed between the two sliding support plates 4, two rotating seats 6 fixedly installed on both sides of the upper end of the bearing plate 5, rotating rods 7 fixedly installed on the two rotating seats 6, opening and closing arc rods 8 rotatably installed on the rotating rods 7, closing cylinder 9 fixedly installed at one end of the opening and closing arc rod 8, embedding groove 10 opened inside the closing cylinder 9, mold cylinder 11 slidably installed in the embedding groove 10, and mold groove 12 opened inside the mold cylinder 11.

[0043] A telescopic rod 32 is fixedly installed on the upper end of the sliding support plate 4, and a hinge rod 33 is installed on the end of the opening and closing arc rod 8 away from the closing cylinder 9. The telescopic end of the telescopic rod 32 is fixedly connected to the hinge rod 33.

[0044] Workers control the angle of the opening and closing arc rod 8 through the telescopic end of the telescopic rod 32. When the angle of the opening and closing arc rod 8 is controlled, the opening and closing arc rod 8 can control the close contact and separation of the two closed cylinders 9. When the two closed cylinders 9 are separated, the molten glass can be placed inside the mold groove 12. When the two closed cylinders 9 are close, the mold groove 12 inside them cooperates to form a complete glass bottle. At this time, when the molten glass is blown, the expanding molten glass can continuously spread outward and adhere to the inner wall of the mold groove 12. After the expansion is completed, the molten glass is blown into the shape of a glass bottle.

[0045] A limit unlocking assembly is installed between the mold cylinder 11 and the closed cylinder 9. A support base 13 is installed on the upper end of the mounting base plate 1. A load-bearing plate 14 is fixedly installed on the side wall of the support base 13. An interlocking plate 15 is fixedly installed on the side wall of the bearing plate 5. A servo rod is fixedly installed on the load-bearing plate 14. A push rod 16 is fixedly installed on the side wall of the interlocking plate 15. One end of the push rod 16 is fixedly connected to the telescopic end of the servo rod.

[0046] Specifically, the function of the mold transfer component is to prevent the existing pressure blow molding device from blowing molten glass into the initial shape of a bottle. The molten glass itself is fluid, and under the action of gravity, the molten solution will accumulate at the bottom of the bottle, resulting in uneven thickness of the glass bottle. In addition, if there is a deviation in the angle at which the high-pressure airflow enters the glass bottle during the blowing process, the airflow distribution inside the glass bottle will be uneven, which may also lead to uneven thickness of the bottle.

[0047] The mold-turning component is designed so that, before blowing the molten glass, the molten glass is placed inside the horizontally placed mold cylinder 11, keeping it in a horizontal position. The high-speed rotation of the mold cylinder 11 drives the molten glass inside to rotate synchronously. During the high-speed rotation, the centrifugal force generated by the molten glass, along with the fact that the sidewall of the glass bottle is always alternately at the bottom during the rotation, avoids the influence of gravity. The centrifugal force from the high-speed rotation ensures that the flowing molten glass can spread outward more quickly and adhere tightly to the inner wall of the mold groove 12. Therefore, the centrifugal force ensures more uniform diffusion of the molten glass while accelerating the overall blowing time, effectively reducing the overall glass blowing time of this device, reducing energy consumption during the glass blowing process, and lowering production costs.

[0048] The challenge in designing the mold-changing component lies in the need for the two mold cylinders 11 to cooperate. When the two mold cylinders 11 and the closed cylinder 9 are in close contact, they form a complete cylindrical shape, with the internal mold groove 12 forming a complete glass bottle shape. Therefore, the two mold cylinders 11 must be set in a separate state so that the molten glass can be placed in the mold groove 12 and the glass bottle can be removed after blowing. At the same time, when the two mold cylinders 11 are in close contact, they are in a rotatable state so that they can rotate freely at high speed during subsequent blowing. When the two mold cylinders 11 are separated, they are respectively limited and fixed inside the closed cylinder 9 to prevent the mold cylinders 11 from shifting in position within the closed cylinder 9, which could lead to failure to overlap later, thus improving the overall stability of the device.

[0049] During use, when the molten glass needs further shaping by blowing, the two closed cylinders 9 are separated, and the molten glass is placed between the two closed cylinders 9. Then, the two closed cylinders 9 are tightly closed. High-pressure gas is then injected into the molten glass, causing the two mold cylinders 11 to rotate at high speed. During the high-speed rotation of the mold cylinders 11, the molten glass being blown inside rotates synchronously, and the side walls of the mold cylinders 11 are alternately located at the bottom, which can effectively reduce the impact of gravity on the molten glass, thereby effectively improving the uniformity of the molten glass thickness. During the rotation, the molten glass can be assisted by centrifugal force to diffuse outward and adhere tightly to the inner wall of the mold groove 12, further accelerating the diffusion of high-pressure gas into the molten glass, reducing the high-pressure gas injection time, effectively reducing energy consumption in the molten glass production process, and reducing costs.

[0050] Example 2, refer to Figures 1-10 This is the second embodiment of the present invention, which differs from the first embodiment in that: the limiting and unlocking assembly includes limiting grooves 17 formed on the two closed cylinders 9, an installation groove 18 formed on the mold cylinder 11, a positioning plate 19 fixedly installed on the inner wall of the installation groove 18, a return spring 20 fixedly installed on the positioning plate 19, a limiting block 21 fixedly installed on the return spring 20, the upper end of the limiting block 21 being located within the limiting groove 17, a stop rod 22 fixedly installed at the lower end of the limiting block 21, and a linkage plate 23 fixedly installed at the lower end of the stop rod 22. A mating element is installed on the mold cylinder 11. The mating element includes a square groove 24 formed within the mold cylinder 11, a transmission block 25 slidably installed within the square groove 24, and a synchronizing rod 26 fixedly installed at the lower end of the transmission block 25, the lower end of the synchronizing rod 26 being fixedly connected to the upper end of the linkage plate 23.

[0051] Specifically, the function of the limiting and unlocking component is as follows: the mold cylinder 11 is located inside the semi-cylindrical closed cylinder 9, and the mold cylinder 11 is slidably installed inside the closed cylinder 9. When the two closed cylinders 9 are separated, the mold cylinder 11 inside needs to be limited to prevent the mold cylinder 11 from shifting in its internal position, so that the two mold cylinders 11 cannot stick together and affect the subsequent blowing. When the two mold cylinders 11 and the closed cylinder 9 are sticking together, the two mold cylinders 11 can rotate at high speed inside the closed cylinder 9, thereby assisting the high-pressure gas to blow the molten glass.

[0052] The remaining structure is the same as that in Example 1.

[0053] Example 3, referring to Figures 1-2This is the third embodiment of the present invention, which differs from the second embodiment in that: the rotary blowing component includes a back plate 27 fixedly mounted on the upper end of the mounting base plate 1, a drive box 28 fixedly mounted on the side wall of the back plate 27, a drive motor (not shown in the figure) fixedly mounted inside the drive box 28, a transfer cylinder 29 fixedly mounted on the side wall of the drive box 28, and a pressure blowing groove 34 formed at the axis of the transfer cylinder 29. A connecting assembly is installed between the transfer cylinder 29 and the transmission block 25. The connecting assembly includes a sealing ring 30 fixedly mounted on the side end wall of the transfer cylinder 29, and a connecting sleeve 31 fixedly mounted on the side end wall of the transfer cylinder 29. The shape and size of the end face of the inner wall of the connecting sleeve 31 are equal to the shape and size of the end face of the transmission block 25.

[0054] Specifically, the blowing component and the limit unlocking component work together: during the blowing process, the servo rod drives the entire bearing plate 5 to slide horizontally along the sliding groove 2 through the telescopic end and the push rod 16. During the sliding process, one end of the mold cylinder 11 and one end of the transfer cylinder 29 come into contact and press against each other, thereby triggering the limit unlocking component, so that the limit unlocking component no longer limits the mold cylinder 11, allowing the mold cylinder 11 to rotate freely inside the closed cylinder 9, and thus the mold cylinder 11 can rotate synchronously and at high speed with the transfer cylinder 29.

[0055] During use, when the molten glass is inside the mold groove 12, the push rod 16 is driven to move horizontally by the telescopic end of the servo rod. During the movement of the push rod 16, the bearing plate 5 is driven to slide horizontally along the sliding groove 2. During the sliding process, the mold cylinder 11 moves horizontally and is in close contact with the transfer cylinder 29. During the close contact process, the sealing ring 30 and the blow molding groove 34 are connected to the inside of the mold groove 12, and the connecting sleeve 31 is connected to the corresponding transmission block 25, which drives the transmission block 25 to slide a distance inside the square groove 24. During the movement of the transmission block 25, the lower linkage plate 23 is driven to move synchronously through the synchronizing rod 26. During the movement of the linkage plate 23, the limiting block 21 is driven to move downward through the abutment rod 22. When the limiting block 21 moves downward, it no longer limits the limiting groove 17, so that when the transfer cylinder 29 rotates at high speed, the mold cylinder 11 is driven to rotate synchronously at high speed through the connecting sleeve 31 and the transmission block 25.

[0056] The remaining structure is the same as that in Example 2.

[0057] Example 4, refer to Figures 1-11 A method for pressure blowing at the neck of energy-saving glass bottles includes the following steps:

[0058] Raw material melting: Quartz sand, soda ash, limestone and other raw materials are melted at high temperature to form a uniform glass melt.

[0059] Material feeding: The molten glass is cut into quantitative droplets by a feeding machine and dripped into the primary mold.

[0060] Initial pressing: The punch presses downwards to form the initial shape of the bottle mouth and body.

[0061] Transfer: The semi-finished product formed by initial pressing is transferred from the initial mold to the mold cylinder 11 through the transfer cylinder 29.

[0062] Blowing and Shaping: When the molten glass needs to be blown for further shaping, the two closed cylinders 9 are separated and the molten glass is placed between the two closed cylinders 9. Then the two closed cylinders 9 are closed tightly. When the molten glass is inside the mold groove 12, the push rod 16 is driven to move horizontally through the extension end of the servo rod. During the movement, the push rod 16 drives the bearing plate 5 to slide horizontally along the sliding groove 2. During the sliding process, the mold cylinder 11 moves horizontally and the transfer cylinder 29 is in close contact with each other. During the close contact process, the sealing ring 30 and the blow molding groove 34 are connected to the inside of the mold groove 12, and the connecting sleeve 31 is connected to the corresponding transmission block 25. The transmission block 25 is driven to slide a distance inside the square groove 24. During the movement, the transmission block 25 drives the lower linkage plate 23 to move synchronously through the synchronous rod 26. During the movement, the linkage plate 23 drives the limiting block 21 to move downward through the abutment rod 22. When the limiting block 21 moves downward, it no longer limits the limiting groove 17.

[0063] Subsequently, high-pressure gas is injected into the molten glass, and the transfer cylinder 29 is driven to rotate at high speed by the drive motor, which in turn drives the two mold cylinders 11 to rotate at high speed. During the high-speed rotation of the mold cylinders 11, the molten glass being blown inside rotates synchronously, and the side walls of the mold cylinders 11 are alternately located at the bottom, which can effectively reduce the impact of gravity on the molten glass, thereby effectively improving the uniformity of the molten glass thickness. During the rotation, the molten glass can assist the high-pressure gas to diffuse outward under the action of centrifugal force and stick tightly to the inner wall of the mold groove 12, further accelerating the diffusion of high-pressure gas into the molten glass, reducing the high-pressure gas injection time, effectively reducing energy consumption and costs in the molten glass production process.

[0064] Annealing: The formed glass bottle is placed in an annealing furnace for annealing.

[0065] Inspection and Packaging: Defective products are removed through appearance inspection and thickness testing, and qualified products are packaged.
