Description

Technical Field

[0001] The present invention relates to the technical field of glass bottle preparation, and particularly relates to an energy-saving small-mouth press-blow device and method for glass bottles. Background Art

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

[0003] In the existing blowing process, although glass bottles can be effectively prepared through high-pressure gas, there are still the following problems: When the molten glass is blown into the preliminary shape of the bottle, the molten glass itself has fluidity, and due to the action of gravity, the glass solution will accumulate at the bottom of the bottle. This sagging phenomenon will cause the glass at the bottom of the bottle to be relatively thick, while the mouth and side walls of the bottle may be thinner, resulting in uneven thickness of the glass bottle. At the same time, during the blowing process, the air flow blows the glass bottle to expand through the blowing device. If the angle of the high-pressure air flow entering the inside of the glass bottle is deviated and the air flow distribution entering the inside of the glass bottle is uneven, it may also cause uneven thickness of the bottle. Moreover, under the influence of gravity and uneven air flow, the glass bottle needs to be blown under high pressure for a longer time, which not only affects the production efficiency of the glass bottle, but also greatly increases the energy consumption and production cost during the production process. Summary of the Invention

[0004] In view of the problem that the molten glass in the existing technology may cause uneven thickness of the glass bottle due to gravity and air flow angle deviation during the blowing process, an energy-saving small-mouth press-blow device and method for glass bottles are proposed.

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

[0006] The technical solution of the present invention is as follows: An energy-saving small-mouth press-blow device for glass bottles, including a mounting base plate, and further including a horizontal blowing unit arranged on the mounting base plate. The horizontal blowing unit includes a mold rotating component and a blowing rotating component arranged on the mounting base plate; The mold rotating component includes sliding grooves opened on both sides of the mounting base plate, sliding rods slidably arranged in the two sliding grooves, sliding support plates respectively arranged on the side walls of the two sliding rods, a bearing plate arranged between the two sliding support plates, two rotating seats arranged at both sides of the upper end of the bearing plate, a rotating rod arranged on the two rotating seats, an opening and closing arc rod arranged on the rotating rod, a closing cylinder arranged at one end of the opening and closing arc rod, an embedding groove opened inside the closing cylinder, a mold cylinder arranged in the embedding groove, and a mold cavity opened in the mold cylinder; A limit unlocking component is installed between the mold cylinder and the closing cylinder. A support seat is installed at the upper end of the mounting base plate, a load-bearing plate arranged on the side wall of the support seat, an interlocking plate arranged on the side wall of the bearing plate, a servo electric rod arranged on the load-bearing plate, and a push rod arranged on the side wall of the interlocking plate. One end of the push rod is fixedly connected to the telescopic end of the servo electric rod.

[0007] Further, the limit unlocking component includes limit grooves opened on the two closing cylinders, an installation groove opened on the mold cylinder, a positioning plate arranged on the inner wall of the installation groove, a reset spring arranged on the positioning plate, a limit block arranged on the reset spring. The upper end of the limit block is located in the limit groove, a resisting rod arranged at the lower end of the limit block, a linkage plate arranged at the lower end of the resisting rod, and a matching element is installed on the mold cylinder.

[0008] Further, the matching element includes a square groove opened in the mold cylinder, a transmission block slidably arranged in the square groove, and a synchronous rod arranged at the lower end of the transmission block. The lower end of the synchronous rod is fixedly connected to the upper end of the linkage plate.

[0009] Further, the blowing rotating component includes a back plate arranged at the upper end of the mounting base plate, a driving box arranged on the side wall of the back plate, a driving motor arranged in the driving box, a transfer cylinder arranged on the side wall of the driving box, and a press-blow groove opened at the axis of the transfer cylinder. A connection component is installed between the transfer cylinder and the transmission block.

[0010] Further, the connection component includes a sealing ring arranged on the side end wall of the transfer cylinder and a connecting sleeve arranged on the side end wall of the transfer cylinder. The shape and size of the inner wall end face of the connecting sleeve are equal to those of the end face of the transmission block.

[0011] Further, 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.

[0012] Furthermore, an energy-saving small-mouth press-blowing method for glass bottles includes the following steps: Raw material melting: High-temperature melting of raw materials such as quartz sand, soda ash, and limestone to form a uniform glass liquid; Feeding: The glass liquid is cut into quantitative droplets by a feeder and dropped into the primary mold; Primary pressing and forming: The punch presses downward to form the prototypes of the bottle mouth and the bottle body; Transfer: The semi-finished product after primary pressing and forming is transferred from the primary mold to the mold cylinder through a transfer cylinder; Blowing and forming: Inject high-pressure gas into the semi-finished product through a pressure-blowing groove, and drive the mold cylinder to rotate synchronously through the transfer cylinder rotating at high speed, so that the glass expands and evenly adheres to the inner wall of the mold groove to form the final bottle body shape; Annealing treatment: Send the formed glass bottle into an annealing furnace for annealing; Inspection and packaging: Eliminate defective products through appearance inspection, thickness testing, etc., and package the qualified products.

[0013] Furthermore, when the glass bottle is subjected to annealing treatment, the temperature inside the annealing furnace is 500 - 600 degrees Celsius, and it cools down slowly to eliminate the internal stress of the glass bottle and prevent cracking.

[0014] Advantages of the present invention: 1. By setting 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 through the transfer cylinder. The mold cylinder rotating at high speed can make the molten glass distribute more evenly through centrifugal force, and by arranging the mold cylinder horizontally, it can effectively avoid the situation that the thickness between the bottle bottom and the bottle body is inconsistent due to gravity. The horizontal arrangement of the mold cylinder and the centrifugal force generated by high-speed rotation cooperate with each other to effectively avoid the situation of uneven bottle body thickness.

[0015] 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 closing cylinder. When the mold cylinder is in a working state and the transfer cylinder presses against the side end of the mold cylinder, the limit block will no longer limit the mold cylinder, and the mold cylinder can rotate at high speed following the transfer cylinder, ensuring that when the mold cylinder is in a non-working state, the mold cylinder will not rotate and displace relatively, affecting the subsequent combination of the two mold cylinders.

[0016] 3. By setting up a mold cylinder that can rotate at high speed, when high-pressure gas is injected into the molten glass, the centrifugal force assists the high-pressure gas to promote the outward diffusion of the molten glass and closely adhere to the inner wall of the mold cavity. While ensuring uniform distribution of the molten glass, it can accelerate the forming speed of the molten glass, effectively reduce the injection time of the high-pressure gas, and greatly reduce the energy consumption during the preparation of glass bottles. During the high-speed rotation process, even if the angle of the gas entering the molten glass deviates, it will not cause uneven forming of the glass bottle, further improving the uniformity during the preparation of glass bottles.

[0019] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings of the specification.

[0020] Example 1, referring to Figures 1-7 and Figure 11 , which is the first embodiment of the present invention, provides an energy-saving glass bottle small-mouth press-blowing device, including a mounting base plate 1, and further including a horizontal blowing unit mounted on the mounting base plate 1. The horizontal blowing unit includes a rotating mold component and a rotating blowing component mounted on the mounting base plate 1.

[0021] The rotating mold component includes sliding grooves 2 opened on both sides of the mounting base plate 1, sliding rods 3 slidably mounted in the two sliding grooves 2, sliding support plates 4 respectively fixedly mounted on the side walls of the two sliding rods 3, a bearing plate 5 fixedly mounted between the two sliding support plates 4, two rotating seats 6 fixedly mounted on both sides of the upper end of the bearing plate 5, a rotating rod 7 fixedly mounted on the two rotating seats 6, an opening and closing arc rod 8 rotatably mounted on the rotating rod 7, a closing cylinder 9 fixedly mounted at one end of the opening and closing arc rod 8, an embedding groove 10 opened inside the closing cylinder 9, a mold cylinder 11 slidably mounted in the embedding groove 10, and a mold cavity 12 opened in the mold cylinder 11.

[0022] An expansion rod 32 is fixedly mounted at the upper end of the sliding support plate 4, and a hinge rod 33 is mounted at the end of the opening and closing arc rod 8 away from the closing cylinder 9. The telescopic end of the expansion rod 32 is fixedly connected to the hinge rod 33.

[0023] The staff controls the angle of the opening and closing arc rod 8 through the telescopic end of the expansion rod 32. When controlling the angle of the opening and closing arc rod 8, the opening and closing arc rod 8 can control the close contact and separation of the two closing cylinders 9. When the two closing cylinders 9 are separated, the glass melt can be placed inside the mold cavity 12. When the two closing cylinders 9 are in close contact, the mold cavities 12 inside them cooperate with each other to form a complete glass bottle. At this time, when the glass melt is press-blown, the expanded glass melt can continuously diffuse outward and closely adhere to the inner wall of the mold cavity 12. When the expansion is completed, the molten glass is blown into the shape of a glass bottle.

[0024] A limit unlocking component is installed between the mold cylinder 11 and the closing cylinder 9. A support seat 13 is installed at the upper end of the mounting base plate 1, a load-bearing plate 14 fixedly mounted on the side wall of the support seat 13, an interlocking plate 15 fixedly mounted on the side wall of the bearing plate 5, a servo electric rod fixedly mounted on the load-bearing plate 14, and a push rod 16 fixedly mounted 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 electric rod.

[0025] Specifically, the function of the mold rotating component is as follows: to avoid the situation that when the existing press-blowing device blows the molten glass into the initial shape of a bottle, the molten glass itself has fluidity, and under the action of gravity, the molten solution will accumulate at the bottom of the bottle bottom, resulting in uneven thickness of the glass bottle. Moreover, during the blowing process, if the angle of the high-pressure air flow entering the interior of the glass bottle is deviated and the air flow distribution entering the interior of the glass bottle is uneven, it may also cause uneven thickness of the bottle.

[0026] With the setting of the mold rotating component, before the device blows the molten glass, the molten glass is placed inside the horizontally placed mold cylinder 11, so that the molten glass is in a horizontal state, and through the high-speed rotation of the mold cylinder 11, the molten glass inside is driven to rotate synchronously. During the high-speed rotation of the molten glass, the centrifugal force generated by it and during the rotation process, the side walls of the glass bottle are always alternately located at the bottommost position. Thus, the influence brought by gravity can be avoided, and through the centrifugal force of high-speed rotation, it can ensure that the flowing molten glass can spread outward faster and closely adhere to the inner wall of the mold groove 12. Therefore, while the centrifugal force can ensure more uniform diffusion of the molten glass, it can accelerate the overall blowing time, effectively reduce the overall glass blowing time of the device, reduce the energy consumption during the glass blowing process, and reduce the production cost.

[0027] At the same time, the difficulty in setting the mold rotating component is as follows: the two mold cylinders 11 need to cooperate with each other. When the two mold cylinders 11 and the closing cylinder 9 are closely attached to each other, they form a complete cylindrical shape, and the mold groove 12 inside forms a complete glass bottle shape. Therefore, the two mold cylinders 11 must be set in a separated state so that the molten glass can be placed in the mold groove 12 and the glass bottle can be taken out after blowing. At the same time, when the two mold cylinders 11 are closely attached to each other, the mold cylinders 11 are in a state where they can rotate, so that during the subsequent blowing process, the mold cylinders 11 can rotate freely at high speed. When the two mold cylinders 11 are separated, the two mold cylinders 11 are respectively limited and fixed inside the closing cylinder 9 to prevent the position of the mold cylinders 11 inside the closing cylinder 9 from shifting, resulting in the situation that they cannot coincide subsequently, and improving the overall stability of the device.

[0028] During use, when the molten glass needs to be further shaped 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 closely closed. Subsequently, high-pressure gas is injected into the molten glass, and the two mold cylinders 11 are driven to rotate at high speed. During the high-speed rotation of the mold cylinders 11, the molten glass being blown inside is driven to rotate synchronously. Moreover, the side walls of the mold cylinders 11 are constantly alternately located at the bottommost position, thereby effectively reducing the influence of gravity on the molten glass, effectively improving the uniformity of the thickness of the molten glass. And the molten glass during rotation can, under the action of centrifugal force, assist the high-pressure gas to diffuse outward and closely adhere to the inner wall of the mold groove 12, further accelerating the diffusion of the high-pressure gas to the molten glass, reducing the injection time of the high-pressure gas, effectively reducing the energy consumption during the production of the molten glass, and reducing costs.

[0029] Example 2, referring to Figures 1-10 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the limit unlocking assembly includes a limit groove 17 opened on the two closed cylinders 9, an installation groove 18 opened 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 limit block 21 fixedly installed on the return spring 20, the upper end of the limit block 21 is located in the limit groove 17, a resisting rod 22 fixedly installed at the lower end of the limit block 21, a linkage plate 23 fixedly installed at the lower end of the resisting rod 22, and a matching element is installed on the mold cylinder 11. The matching element includes a square groove 24 opened in the mold cylinder 11, a transmission block 25 slidably installed in the square groove 24, a synchronous rod 26 fixedly installed at the lower end of the transmission block 25, and the lower end of the synchronous rod 26 is fixedly connected to the upper end of the linkage plate 23.

[0030] Specifically, the function of the limit unlocking assembly 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 position inside, resulting in the subsequent inability of the two mold cylinders 11 to be closely attached, affecting subsequent blowing. And when the two mold cylinders 11 and the closed cylinder 9 are closely attached to each other, at this time, the two mold cylinders 11 can rotate at high speed inside the closed cylinder 9, thereby assisting the blowing of the high-pressure gas to the molten glass.

[0031] The remaining structures are the same as those in Embodiment 1.

[0032] Example 3, referring to Figures 1-2, which is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the rotary blowing component includes a back plate 27 fixedly installed at the upper end of the installation base plate 1, a driving box 28 fixedly installed on the side wall of the back plate 27, a driving motor (not shown in the figure) fixedly installed in the driving box 28, a transfer cylinder 29 fixedly installed on the side wall of the driving box 28, a pressure blowing groove 34 opened at the axis of the transfer cylinder 29, and a connection component is installed between the transfer cylinder 29 and the transmission block 25. The connection component includes a sealing ring 30 fixedly installed on the side end wall of the transfer cylinder 29, a connecting sleeve 31 fixedly installed on the side end wall of the transfer cylinder 29, and the end face shape and size 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.

[0033] Specifically, the rotary blowing component cooperates with the limit unlocking component: during the blowing process, the servo electric 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 die cylinder 11 contacts and presses against one end of the transfer cylinder 29, thereby triggering the limit unlocking component, causing the limit unlocking component to no longer limit the die cylinder 11, enabling the die cylinder 11 to rotate freely inside the closing cylinder 9 normally, and thus the die cylinder 11 can rotate synchronously at high speed with the transfer cylinder 29.

[0034] During use, after the molten glass is located inside the mold cavity 12, the push rod 16 is driven to move horizontally along the telescopic end of the servo electric 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, when the die cylinder 11 moves horizontally, the die cylinder 11 is in close contact with the transfer cylinder 29. During the close contact process, the sealing ring 30 and the pressure blowing groove 34 are communicated with the inside of the mold cavity 12, and the connecting sleeve 31 is connected to the corresponding transmission block 25, and drives the transmission block 25 to slide a certain 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 abutting 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 die cylinder 11 is driven to rotate synchronously at high speed through the connecting sleeve 31 and the transmission block 25.

[0035] The remaining structures are the same as those in Embodiment 2.

[0036] Embodiment 4, referring to Figures 1-11 , an energy-saving small-mouth pressure blowing method for glass bottles, includes the following steps: Raw material melting: High-temperature melting of raw materials such as quartz sand, soda ash, and limestone to form a uniform glass liquid.

[0037] Feeding: The glass liquid is cut into quantitative droplets by a feeder and dropped into the primary mold.

[0038] Initial pressing forming: The punch presses downward to form the prototypes of the bottle mouth and the bottle body.

[0039] Transfer: The semi-finished product after initial pressing forming is transferred from the initial mold to the mold cylinder 11 through the transfer cylinder 29.

[0040] Blow forming: When the molten glass needs to be further shaped by blowing, separate the two closing cylinders 9, place the molten glass between the two closing cylinders 9, and then tightly close the two closing cylinders 9. After the molten glass is inside the mold cavity 12, drive the push rod 16 to move horizontally along the telescopic end of the servo electric rod. During the movement of the push rod 16, drive the bearing plate 5 to slide horizontally along the sliding groove 2. During the sliding process, when the mold cylinder 11 moves horizontally, the mold cylinder 11 is in close contact with the transfer cylinder 29. During the close contact process, the sealing ring 30 and the pressure-blowing groove 34 are in communication with the inside of the mold cavity 12, and the connecting sleeve 31 is connected to the corresponding transmission block 25, and drives the transmission block 25 to slide a certain distance inside the square groove 24. During the movement of the transmission block 25, drive the linkage plate 23 at the lower end to move synchronously through the synchronizing rod 26. During the movement of the linkage plate 23, drive the limiting block 21 to move downward through the abutting rod 22. When the limiting block 21 moves downward, it no longer limits the limiting groove 17; Subsequently, inject high-pressure gas into the molten glass, drive the transfer cylinder 29 to rotate at high speed through the drive motor, and drive the two mold cylinders 11 to rotate at high speed. During the high-speed rotation of the mold cylinder 11, drive the molten glass blown inside to rotate synchronously, and the side wall of the mold cylinder 11 is continuously alternately located at the bottommost, thereby effectively reducing the influence of gravity on the molten glass, effectively improving the uniformity of the thickness of the molten glass, and the molten glass during rotation can assist the high-pressure gas to diffuse outward under the action of centrifugal force and closely adhere to the inner wall of the mold cavity 12, further accelerating the diffusion of the high-pressure gas to the molten glass, reducing the injection time of the high-pressure gas, effectively reducing the energy consumption during the production of the molten glass, and reducing the cost.

[0041] Annealing treatment: Send the formed glass bottle into the annealing furnace for annealing.

[0042] Inspection and packaging: Eliminate defective products through appearance inspection, thickness testing, etc., and package the qualified products.
