Description

Technical Field

[0001] This utility model relates to the field of glass bottle blowing technology, and in particular to a glass bottle blowing device. Background Technology

[0002] Glass bottle blowing is an important process in the glass manufacturing industry, which usually uses high-temperature hot air or compressed air to blow molten glass into shape;

[0003] To this end, patent CN217052025U discloses a glass bottle blowing device, which includes: a blow molding tube, a movable component, and a shaping component. The movable component includes a movable sleeve, an annular groove, a rotating sleeve, and a telescopic rod. The movable sleeve is fitted onto the outer wall of the blow molding tube. An annular groove is provided at the lower end of the outer wall of the movable sleeve. A rotating sleeve is provided inside the annular groove. A telescopic rod is provided laterally on the side wall of the rotating sleeve. The shaping component is connected to the end of the telescopic rod. The shaping component includes a connecting plate, a mounting plate, a screw, a shaping ball, a shaping arc plate, and a shaping block. The upper end of the connecting plate is connected to the end of the telescopic rod. The lower end of the connecting plate is provided with a mounting plate. The shaping ball is used to create a concave shape on the outer wall of the glass bottle. The shaping arc plate is used to create a curved shape on the outer wall of the glass bottle. The shaping block is used to create a flat shape on the outer wall of the glass bottle, which facilitates different forms of shaping and blowing on the outer wall of the glass bottle.

[0004] The existing technical solutions mentioned above have the following drawbacks: the blowing process mostly adopts unidirectional airflow, that is, hot air is directly blown into the mold and then discharged without recycling. The high-temperature gas is directly discharged after blowing is completed and is not effectively recycled, resulting in energy waste and increased enterprise operating costs. The fixed blowing channel makes it impossible to switch the ventilation or recycling state according to different working conditions or blowing needs, resulting in a single gas flow path and inconvenient adjustment. Utility Model Content

[0005] The purpose of this invention is to provide a glass bottle blowing device to overcome the shortcomings of an existing glass bottle blowing device.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a glass bottle blowing device, comprising an outer cylinder and an inner cylinder, wherein an air outlet is fixedly provided at the top opening of the outer cylinder, the inner cylinder is slidably inserted into the outer cylinder and the air outlet, and a sealing ring is fixedly provided in the middle section of the outer wall of the inner cylinder;

[0007] The air outlet is equipped with a lifting component, which is used to control the inner cylinder to slide on the outer cylinder. The sliding action of the inner cylinder acts on the sealing ring to complete the seal between the inner cylinder and the outer cylinder.

[0008] A limiting component is fixedly provided at the bottom of the inner wall of the outer cylinder, and the limiting component is used to limit the movement trajectory of the inner cylinder.

[0009] The air outlet is provided with a recovery port, and the upper end of the outer cylinder is provided with an air inlet.

[0010] Preferably, the lifting assembly includes an electromagnet, an iron base, a spring, a base plate, and a connecting rod. The connecting rod is fixedly disposed on the upper surface of the air outlet cylinder, the base plate is fixedly disposed on the top end of the connecting rod, and the electromagnet is fixedly disposed on the base plate.

[0011] Preferably, the iron base is fixedly disposed at the top of the inner cylinder, the spring is sleeved on the inner cylinder and abuts against the air inlet and the base plate, and the spring applies an elastic thrust to the inner cylinder away from the electromagnet.

[0012] Preferably, the limiting component includes a limiting ring and a fixing block. The fixing block is fixedly provided at equal intervals on the outer wall of the limiting ring. The other end of the fixing block is fixedly provided on the inner wall of the outer cylinder. The inner wall of the limiting ring is symmetrically provided with sliding grooves. The outer wall of the inner cylinder is symmetrically provided with sliders, which are slidably inserted into the sliding grooves.

[0013] Preferably, a sliding sealing structure is provided at the sliding connection between the air outlet and the inner cylinder.

[0014] Preferably, a gasket is fixedly provided at the bottom end of the outer cylinder, and mounting holes are symmetrically provided on the gasket.

[0015] The glass bottle blowing equipment provided by this utility model has the following advantages:

[0016] The blowing structure for blowing glass bottles can be set in a designated position through the mounting holes on the gasket. It is connected to an external air supply source through the air inlet and to an external recovery pipeline through the recovery port. During use, the blowing equipment moves the device so that the gasket rests against the air outlet of the blowing mold. Hot air enters the inner cylinder through the air inlet and is sent into the blowing mold through the inner cylinder. The exhaust gas after blowing enters the outer cylinder and then enters the exhaust cylinder. Finally, it is collected through the recovery port of the exhaust cylinder, thereby recovering the hot air and guiding it to the preheating area. After preheating, it can be reused, reducing the waste of gas heat.

[0017] Furthermore, by improving the design of the components, when it is necessary to close the exhaust gas recovery passage, an external power source is connected to make the electromagnet work. The electromagnet magnetically attracts the iron base, and under the magnetic attraction, it guides the inner cylinder to move upward. At this time, the spring is compressed and deformed, and the inner cylinder drives the sealing ring to move upward, so that the rubber sealing ring abuts against the top of the inner wall of the outer cylinder, thereby cutting off the exhaust gas recovery passage. Conversely, when the electromagnet is disconnected, the inner cylinder is reset under the elastic force of the spring, and the sealing ring moves away from the outer cylinder, thus opening the exhaust gas recovery passage.

[0018] Furthermore, through the design of the limiting component, the outer wall of the inner cylinder is slidably inserted into the limiting ring, and the fiber ring limits the movement trajectory of the inner cylinder to prevent it from deflecting.

[0019] By setting a recovery port in the exhaust pipe, the exhaust gas after blowing is guided to an external recovery pipeline, and the hot air can be recovered to the preheating area for recycling, reducing heat waste and improving energy efficiency.

[0020] By setting up a lifting component structure to control the sliding of the inner cylinder, the airflow channel is switched by the sliding of the sealing ring driven by the inner cylinder, realizing flexible switching between blowing state and waste gas recovery state, meeting different process requirements, and improving equipment applicability. The outer wall of the inner cylinder is equipped with a sealing ring, which, together with the sliding sealing structure of the outer cylinder and the air outlet, achieves effective sealing of the blowing gas under high temperature and high pressure conditions, prevents hot air leakage, and maintains stable blowing pressure.

[0021] By setting up a limit component structure, the movement trajectory of the inner cylinder is limited, avoiding deviation or jamming during the sliding process, thereby improving the stability and reliability of the equipment operation and extending the service life of the equipment.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figure 1-5 The present invention provides a glass bottle blowing device, including a gasket ring 1, an outer cylinder 2, an air outlet cylinder 3, an inner cylinder 4, a lifting component 5, an air inlet 6, a recovery port 7, a limiting component 8, and a sealing ring 9.

[0031] In this embodiment, the outer cylinder 2 is a hollow cylindrical structure, with an air outlet 3 fixedly installed at its top opening. The inner cylinder 4 is slidably inserted between the outer cylinder 2 and the air outlet 3, and can slide axially inside the outer cylinder 2. A sealing ring 9 is fixedly installed in the middle section of the outer wall of the inner cylinder 4 to achieve a sealing fit between the outer cylinder 2 and the inner cylinder 4 during the sliding process.

[0032] Example 2

[0033] This embodiment also includes: a lifting assembly 5 installed above the air outlet 3, the lifting assembly 5 including an electromagnet 501, an iron base 502, a spring 503, a base plate 504 and a connecting rod 505.

[0034] In this embodiment, the connecting rod 505 is fixedly installed on the upper surface of the air outlet cylinder 3, the base plate 504 is fixedly installed on the top end of the connecting rod 505, and the electromagnet 501 is fixedly installed on the base plate 504. The iron base 502 is fixedly installed on the top end of the inner cylinder 4, and the spring 503 is sleeved on the inner cylinder 4, located between the air inlet 6 and the base plate 504. The spring 503 applies an elastic thrust to the inner cylinder 4 in a direction away from the electromagnet 501.

[0035] During equipment operation, if it is necessary to close the waste gas recovery passage, an external power source can be used to energize electromagnet 501. Electromagnet 501 generates a magnetic attraction force on iron base 502, causing inner cylinder 4 to move upward. During the upward movement of inner cylinder 4, sealing ring 9 moves to the top of the inner wall of outer cylinder 2, forming a seal with outer cylinder 2 and cutting off the flow path of recovered gas. If the power supply to electromagnet 501 is disconnected, inner cylinder 4 returns to its original position under the elastic force of spring 503, sealing ring 9 moves away from the inner wall of outer cylinder 2, waste gas recovery passage opens, and hot air can be recovered and reused through recovery port 7.

[0036] Example 3

[0037] This embodiment also includes: a limiting component 8 is fixedly installed at the bottom of the inner wall of the outer cylinder 2 to limit the movement trajectory of the inner cylinder 4, prevent it from deviating, and maintain the sliding accuracy. The limiting component 8 includes a limiting ring 801 and a fixing block 802. Multiple fixing blocks 802 are fixedly installed at equal intervals on the outer wall of the limiting ring 801. The other end of the fixing block 802 is fixed on the inner wall of the outer cylinder 2.

[0038] In this embodiment, the inner wall of the limiting ring 801 is symmetrically provided with grooves, and the outer wall of the inner cylinder 4 is symmetrically fixed with sliders. The sliders are slidably inserted into the grooves to ensure that the inner cylinder 4 slides smoothly along the axial direction.

[0039] A gasket 1 is fixedly installed at the bottom of the outer cylinder 2. The gasket 1 has symmetrical mounting holes to facilitate fixing the equipment at the air blowing port of the blow molding die. In use, the external air supply is connected through the air inlet 6 to introduce hot air into the inner cylinder 4. The hot air is sent into the blow molding die along the inner cylinder 4 to complete the glass blowing. The exhaust gas after blowing flows back along the outer cylinder 2 and is discharged through the recovery port 7 of the air outlet 3. It can be connected to an external recovery pipeline to guide the exhaust gas to the preheating area for reuse, thereby improving the thermal energy utilization rate.

[0040] Furthermore, a sliding seal structure is provided at the sliding connection between the air outlet 3 and the inner cylinder 4 to improve the gas sealing performance and prevent hot air leakage during the sliding process.

[0041] In summary, through the above structural design, the glass bottle blowing equipment of the present invention can switch between blowing and waste gas recovery channels through simple mechanical components, thereby improving blowing efficiency, reducing energy consumption, simplifying operation procedures, and being suitable for glass bottle blowing operations under different working conditions. It has good promotion and application value.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
