Description

Technical Field

[0001] This utility model relates to the field of glass bottle production, and in particular to an air outlet structure for an air blowing head at the mouth of a glass bottle. Background Technology

[0002] In the glass bottle blowing process, the blowing head is the core component used to blow high-pressure gas into the forming mold to form the glass preform. Traditional blowing heads usually adopt an integrated cooling structure with a cooling chamber at the bottom. Inside the cooling chamber, there is a blowing chamber with a blowing tube. When the blowing head is installed in the forming mold, the bottle mouth of the glass bottle is in close contact with the blowing chamber, so that the blowing tube extends into the bottle mouth. When the blowing gas source supplies gas to the blowing tube, the blowing tube blows and shapes the inside of the glass bottle. In order to accelerate the solidification of the bottle mouth, cooling air inlets and outlets are opened on the outer edge of the blowing head. The cooling air inlets are connected to an external cooling gas source. The gas enters the cooling chamber through the cooling air inlets, circulates, and is discharged from the outlets to remove heat from the bottle mouth area.

[0003] In actual production lines, the cooling air source is usually far from the blowing head. The cooling air source needs to transport the gas to the blowing head through a long pipeline. During the transportation process, the gas will experience pressure loss due to pipeline friction, bend resistance, and minor leakage. Therefore, the cooling air source usually needs to increase the gas supply. Due to the long distance, there is a pressure transmission delay in the pipeline from the cooling air source to the blowing head. Therefore, it is difficult to adjust the gas supply of the cooling air source to make the air pressure in the cooling chamber reach the standard value of the process. If the air pressure in the cooling chamber of the blowing head is slightly high, the cooling rate in the bottle mouth area will exceed the process set threshold, causing the bottle mouth to solidify and shrink prematurely under rapid cooling, resulting in a smaller inner diameter of the bottle mouth. If the air pressure in the cooling chamber of the blowing head is slightly low, the cooling rate in the bottle mouth area will be less than the process set threshold. After the mold opens and closes, when the robot grabs the bottle mouth of the glass bottle that has not been fully cooled, the bottle mouth is easily deformed by external mechanical force, resulting in a decrease in the yield of the glass bottle. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an air outlet structure for a blowing head at the mouth of a glass bottle. The purpose is to solve the technical problem that, because the cooling gas source is far from the blowing head, there is a pressure transmission delay in the gas pipeline from the cooling gas source to the blowing head, making it difficult to adjust the gas supply of the cooling gas source to make the air pressure in the cooling chamber reach the standard value of the process.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] An air outlet structure for a glass bottle mouth includes an air outlet body. A cooling chamber is formed at the bottom of the air outlet body, and a blowing chamber is formed inside the cooling chamber. A blowing tube is provided inside the blowing chamber. Multiple first air inlets and multiple first exhaust holes are provided along the outer edge of the air outlet body. The multiple first air inlets and multiple first exhaust holes are respectively connected to the cooling chamber. The first air inlets are connected to an external cooling air source. Multiple adjusting seats are provided along the outer edge of the air outlet body, and the multiple adjusting seats correspond to the multiple first exhaust holes. An adjusting cavity is formed at one end of each adjusting seat. An isolation plate is slidably connected inside the adjusting cavity, and the isolation plate divides the adjusting cavity into an exhaust cavity and a connecting cavity. The exhaust cavity is connected to an adjacent first exhaust hole, and the connecting cavity is away from the first exhaust hole. Multiple second exhaust holes are formed on one side of the adjusting seat, and the exhaust cavity and the connecting cavity are connected to adjacent second exhaust holes.

[0007] When supplying cooling air, the air supply volume is pre-increased to slightly exceed the theoretical requirement to compensate for pressure losses caused by pipeline friction, bend resistance, and minor leaks during long-distance transportation. At this point, the cooling airflow enters the cooling chamber through the first inlet. When the actual air pressure reaching the cooling chamber is found to be lower than the process standard value, the operator adjusts the position of the isolation plate within the adjustment cavity, moving it closer to the first exhaust port. This reduces the volume ratio of the exhaust cavity while increasing the volume of the connecting cavity. This reduces the number of connecting holes between the exhaust cavity and the second exhaust port, slowing the exhaust gas discharge rate from the cooling chamber. More high-pressure airflow remains and circulates within the cooling chamber, raising the air pressure within the cooling chamber to the standard value. If the actual cooling chamber pressure exceeds the process standard value, the operator adjusts the position of the isolation plate within the adjustment cavity, moving the isolation plate away from the first exhaust port. This increases the proportion of the exhaust cavity volume, reduces the volume of the connecting cavity, and increases the number of connecting holes between the exhaust cavity and the second exhaust port, allowing the gas in the cooling chamber to be discharged quickly. This reduces the gas pressure in the cooling chamber to the standard value. By adjusting the position of the isolation plate to preset the exhaust resistance, the gas pressure in the cooling chamber can be adjusted in real time. This design upgrades the traditional passive mode that relies on remote cooling gas source adjustment to an active control mode based on local structural optimization, significantly improving the stability and adaptability of the bottle mouth cooling process.

[0008] Furthermore, in this application, the other end of the adjusting seat is provided with an adjusting hole, the adjusting hole is connected to the connecting cavity, and an adjusting screw is threaded inside the adjusting hole. One end of the adjusting screw passes through the connecting cavity, so that one end of the adjusting screw is connected to the isolation plate.

[0009] The adjusting screw is screwed into the adjusting cavity through a thread, and one end of it is rigidly connected to the isolation plate. When the operator rotates the adjusting screw, the rotational motion of the thread is converted into the linear displacement of the isolation plate. This structure directly converts manual rotation operation into position movement control of the isolation plate, thereby facilitating the adjustment of the volume of the connecting cavity and the exhaust cavity.

[0010] Furthermore, in this application, the other end of the adjusting screw extends out of the adjusting hole, and the other end of the adjusting screw is provided with a rotating block. A slot is formed on one side of the rotating block, and the slot is used for screwdriver rotation.

[0011] When the operator inserts a flathead screwdriver into the slot of the rotating block and rotates it, the rotating block drives the adjusting screw to rotate synchronously. The adjusting screw moves axially under the thread constraint of the adjusting cavity, thus avoiding the operator's hand touching the rotating block when the adjusting screw needs to be rotated, and preventing the operator from being burned by the rotating block.

[0012] Furthermore, in this application, a fixing hole is provided on the other side of the adjusting seat, the fixing hole is connected to the adjusting hole, and a fixing bolt is threaded into the fixing hole, the fixing bolt abutting against the adjusting screw.

[0013] Furthermore, in this application, a setting groove is provided on one side of the adjusting seat, the setting groove connects the connecting cavity and the exhaust cavity, an exhaust plate is provided inside the setting groove, and a plurality of second exhaust holes are provided inside the exhaust plate.

[0014] Furthermore, in this application, a sealing ring is fitted around the outer edge of the isolation disc. The sealing ring is elastic, and the outer edge of the sealing ring abuts against the interior of the adjustment cavity.

[0015] Furthermore, in this application, the outer edge of the isolation disc is provided with a mounting groove, the mounting groove is matched with the shape of the sealing ring, and the sealing ring is located inside the mounting groove.

[0016] Furthermore, in this application, the sealing ring is a high-temperature resistant sealing ring.

[0017] Furthermore, in this application, the top of the air blowing head body is provided with a mounting end, and the top of the mounting end is provided with a second air inlet, which is connected to an external air blowing source.

[0018] Furthermore, in this application, mounting extension blocks are provided on both sides of the mounting end, and a mounting slot is provided on one side of the mounting extension block. The mounting slot is used to connect with the transmission mechanism of the column machine.

[0019] This utility model has the following beneficial effects:

[0020] When supplying cooling air, the air supply volume is pre-increased to slightly exceed the theoretical requirement to compensate for pressure losses caused by pipeline friction, bend resistance, and minor leaks during long-distance transportation. At this point, the cooling airflow enters the cooling chamber through the first inlet. When the actual air pressure reaching the cooling chamber is found to be lower than the process standard value, the operator adjusts the position of the isolation plate within the adjustment cavity, moving it closer to the first exhaust port. This reduces the volume ratio of the exhaust cavity while increasing the volume of the connecting cavity. This reduces the number of connecting holes between the exhaust cavity and the second exhaust port, slowing the exhaust gas discharge rate from the cooling chamber. More high-pressure airflow remains and circulates within the cooling chamber, raising the air pressure within the cooling chamber to the standard value. If the actual cooling chamber pressure exceeds the process standard value, the operator adjusts the position of the isolation plate within the adjustment cavity, moving the isolation plate away from the first exhaust port. This increases the proportion of the exhaust cavity volume, reduces the volume of the connecting cavity, and increases the number of connecting holes between the exhaust cavity and the second exhaust port, allowing the gas in the cooling chamber to be discharged quickly. This reduces the gas pressure in the cooling chamber to the standard value. By adjusting the position of the isolation plate to preset the exhaust resistance, the gas pressure in the cooling chamber can be adjusted in real time. This design upgrades the traditional passive mode that relies on remote cooling gas source adjustment to an active control mode based on local structural optimization, significantly improving the stability and adaptability of the bottle mouth cooling process.

[0033] Reference Figures 1-7In some specific embodiments, a blower head air outlet structure for a glass bottle mouth includes a blower head body 1. A cooling chamber 8 is formed at the bottom of the blower head body 1. A blowing chamber 7 is formed inside the cooling chamber 8. A blowing pipe 6 is provided inside the blowing chamber 7. Multiple first air inlets 9 and multiple first air outlets 10 are provided along the outer edge of the blower head body 1. The multiple first air outlets 10 are located below the multiple first air inlets 9. The multiple first air inlets 9 and multiple first air outlets 10 are respectively connected to the cooling chamber 8. The first air inlets 9 are connected to an external cooling air source. The blower head body 1... Multiple adjustment seats 11 are provided on the outer edge, and the multiple adjustment seats 11 correspond to multiple first exhaust holes 10 respectively. An adjustment cavity 12 is opened at one end of the adjustment seat 11. An isolation plate 16 is slidably connected inside the adjustment cavity 12. The isolation plate 16 divides the adjustment cavity 12 into an exhaust cavity 20 and a connecting cavity 19. The exhaust cavity 20 is connected to the adjacent first exhaust hole 10, and the connecting cavity 19 is away from the first exhaust hole 10. Multiple second exhaust holes 15 are opened on one side of the adjustment seat 11. The exhaust cavity 20 and the connecting cavity 19 are connected to the adjacent second exhaust holes 15.

[0034] Through the above technical solution, when supplying cooling air, the air supply volume is pre-increased to slightly higher than the theoretical requirement (e.g., 105%-110% of the standard value) to compensate for pressure loss caused by pipeline friction, bend resistance, and minor leakage during long-distance transportation. At this time, the cooling airflow enters the cooling chamber 8 through the first air inlet 9. When it is found that the actual air pressure reaching the cooling chamber 8 is lower than the process standard value (for example, if the bottle mouth curing is found to be insufficient, causing deformation when the robot grips the bottle mouth, or if a pressure sensor is installed inside the cooling chamber 8 to identify insufficient air pressure), the operator adjusts the position of the isolation plate 16 within the adjustment cavity 12 (e.g., ...). (By fixing with bolts), the isolation plate 16 moves closer to the first exhaust port 10, reducing the volume percentage of the exhaust cavity 20 (e.g., from 60% to 40%), while increasing the volume of the connecting cavity 19 (e.g., from 40% to 60%). At this point, the number of connecting holes between the exhaust cavity 20 and the second exhaust port 15 decreases (e.g., 3 out of the original 5 second exhaust ports 15 are isolated by the isolation plate 16). Since the connecting cavity 19 is not connected to the first exhaust port 10, cooling gas will not be discharged from the second exhaust ports 15 connected to the connecting cavity 19 under the isolation of the isolation plate 16, thus only 2 second exhaust ports 15 remain connected to the exhaust cavity 20. This reduces the exhaust speed of the cooling gas in the cooling chamber 8, causing more cooling airflow to circulate within the cooling chamber 8, thus raising the air pressure in the cooling chamber 8 to the standard value. If the actual pressure reaching the cooling chamber 8 exceeds the process standard value (for example, if premature curing after bottle neck molding causes inner diameter shrinkage, or if a pressure sensor is installed inside the cooling chamber 8 for pressure identification), the operator adjusts the position of the isolation plate 16 within the adjustment cavity 12 (e.g., by bolt fixing), causing the isolation plate 16 to move away from the first exhaust port 10, increasing the volume ratio of the exhaust cavity 20 (e.g., from 30% to 70%), and decreasing the volume of the connecting cavity 19 (e.g., from 7%). (0% to 30%) and the number of connecting holes between the exhaust cavity 20 and the second exhaust port 15 increases (for example, the three second exhaust ports 15 that were originally isolated by the isolation plate 16 are reopened, and a total of two second exhaust ports 15 are connected to the exhaust cavity 20), so that the gas in the cooling cavity 8 is discharged quickly, thereby reducing the gas pressure in the cooling cavity 8 to the standard value. The position of the isolation plate 16 is adjusted to preset the exhaust resistance, so as to adjust the gas pressure in the cooling cavity 8 in real time. This design upgrades the traditional passive mode that relies on remote cooling gas source adjustment to an active control mode based on local structural optimization, which significantly improves the stability and adaptability of the bottle mouth cooling process of glass bottles.

[0035] Reference Figures 5-7 In some specific embodiments, the other end of the adjusting seat 11 is provided with an adjusting hole 23, which is connected to the connecting cavity 19. An adjusting screw 21 is threaded inside the adjusting hole 23, and one end of the adjusting screw 21 passes through the connecting cavity 19 so that one end of the adjusting screw 21 is connected to the isolation plate 16.

[0036] Through the above technical solution, the adjusting screw 21 is screwed into the adjusting hole through the thread, and one end of it passes through the connecting cavity 19 and is rigidly connected to the isolation plate 16. When the operator rotates the adjusting screw 21, the rotational motion of the thread is converted into the linear displacement of the isolation plate 16 (for example, clockwise rotation moves the isolation plate 16 toward the first exhaust port 10, and counterclockwise rotation moves it in the opposite direction). This structure directly converts the manual rotation operation into position movement control of the isolation plate 16, thereby facilitating the adjustment of the volume of the connecting cavity 19 and the exhaust cavity 20.

[0037] Reference Figures 5-7 In some specific embodiments, the other end of the adjusting screw 21 extends through the adjusting hole 23, and the other end of the adjusting screw 21 is provided with a rotating block 22. A slot 26 is provided on one side of the rotating block 22 for the screwdriver to rotate.

[0038] With the above technical solution, when the operator inserts a flathead screwdriver into the slot 26 of the rotating block 22 and rotates it, the rotating block 22 drives the adjusting screw 21 to rotate synchronously. The adjusting screw 21 moves axially under the thread constraint of the adjusting cavity 12, thereby avoiding the operator's hand from touching the rotating block 22 when the adjusting screw 21 needs to be rotated, and preventing the operator from being burned by the high temperature of the rotating block 22.

[0039] Reference Figures 5-7 In some specific embodiments, a fixing hole 24 is provided on the other side of the adjusting seat 11. The fixing hole 24 is connected to the adjusting hole 23. A fixing bolt 25 is threaded into the fixing hole 24. The fixing bolt 25 abuts against the adjusting screw 21.

[0040] With the above technical solution, when the cooling gas is discharged at high speed from the second exhaust port 15, the airflow reaction force is transmitted to the isolation plate 16. The cooling airflow may push the adjusting screw 21 to rotate slightly. Therefore, after the adjusting screw 21 is adjusted to the desired position, the fixing bolt 25 is screwed into the fixing hole 24. The static friction force is generated by the thread preload, so that the fixing bolt 25 and the adjusting screw 21 come into contact, thereby restricting the rotational freedom of the adjusting screw 21 and preventing the isolation plate 16 from axially displacing under the impact of the airflow.

[0041] Reference Figures 5-7 In some specific embodiments, a setting groove 13 is provided on one side of the adjusting seat 11. The setting groove 13 connects the connecting cavity 19 and the exhaust cavity 20. An exhaust plate 14 is provided inside the setting groove 13, and a plurality of second exhaust holes 15 are provided inside the exhaust plate 14.

[0042] By using the above technical solution, the installation position of the exhaust plate 14 is limited by the installation groove 17 of the exhaust plate 14 inside the groove 13, thereby improving the accuracy of the installation position of the second exhaust hole 15.

[0043] Furthermore, the exhaust plate 14 can be detachably connected to the setting slot 13. When all the second exhaust holes 15 are connected to the exhaust cavity 20, but the cooling cavity 8 still fails to reach the standard air pressure, the exhaust plate 14 with a larger second exhaust hole 15 can be replaced. When only one second exhaust hole is connected to the exhaust cavity 20, but the cooler still fails to reach the air pressure, the exhaust plate 14 with a smaller second exhaust hole 15 can be replaced, thereby expanding the air pressure adjustment range.

[0044] Reference Figures 5-7 In some specific embodiments, a sealing ring 18 is fitted around the outer edge of the isolation disc 16. The sealing ring 18 is elastic, and the outer edge of the sealing ring 18 abuts against the inside of the adjustment cavity 12.

[0045] With the above technical solution, when the isolation disk 16 slides in the adjustment cavity 12, the elastic sealing ring 18 sleeved on its outer edge always maintains close contact with the inner wall of the adjustment cavity 12. The sealing ring 18 is squeezed and produces elastic deformation, filling the tiny gap between the isolation disk 16 and the adjustment cavity 12, forming a dynamic sealing interface, and blocking the cooling gas from leaking through the edge of the isolation disk 16 to the connecting cavity 19.

[0046] Reference Figures 5-7 In some specific embodiments, the outer edge of the isolation plate 16 is provided with a mounting groove 17, the mounting groove 17 is matched with the shape of the sealing ring 18, and the sealing ring 18 is located inside the mounting groove 17.

[0047] By matching the shape of the mounting groove 17 with that of the sealing ring 18, the radial and circumferential displacement of the sealing ring 18 is limited. This design ensures that the sealing ring 18 remains in the predetermined position when the isolation disc 16 slides, avoiding displacement, twisting or even falling off due to airflow impact or vibration.

[0048] Reference Figures 5-7 In some specific embodiments, the sealing ring 18 is a high-temperature resistant sealing ring 18.

[0049] Through the above technical solution, the high-temperature resistant sealing ring 18 has strong resistance to water vapor, trace acidic substances and lubricating oil mist that may be contained in the cooling gas, thereby avoiding sealing failure caused by swelling or corrosion.

[0050] Reference Figures 1-4 In some specific embodiments, the top of the air blowing head body 1 is provided with a mounting end 2, and the top of the mounting end 2 is provided with a second air inlet 3, which is connected to an external air blowing source.

[0051] With the above technical solution, when the blowing gas source supplies gas to the second air inlet 3, the gas will blow and shape the inside of the glass bottle after passing through the blowing pipe 6, thus facilitating the shaping of the glass bottle.

[0052] Reference Figures 1-4 In some specific embodiments, mounting extension blocks 4 are provided on both sides of the mounting end 2, and a mounting slot 5 is provided on one side of the mounting extension block 4. The mounting slot 5 is used to connect with the transmission mechanism of the row machine.

[0053] Through the above technical solution, the mounting slot 5 is used to connect with the transmission mechanism of the row machine, thereby facilitating the installation of the air blowing head body 1, so that the air blowing head body 1 can be combined with the mold to form a glass bottle.
