Description

Technical Field

[0001] A bottom cooling and polishing mechanism for a bottle-making machine belongs to the field of glass bottle production technology. Background Technology

[0002] When producing high-end glass bottles using traditional bottle-making machines, the polishing mechanism is usually located close to the glass bottle conveying mechanism. For example, patent CN222348887U mentions that the polishing mechanism is positioned on one side of the glass conveying mechanism via a circulating track to polish the glass bottles. Typically, cooling and polishing are performed separately, with cooling preceding polishing. However, after cooling, the bottle's temperature is already low, requiring significant energy to achieve the desired polishing results, leading to some waste. If the polishing mechanism is located after the forming station, fully utilizing the residual heat of the formed bottle to reduce energy consumption, then a corresponding cooling method needs to be considered, requiring simultaneous polishing and cooling. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a bottom cooling and polishing mechanism for a bottle making machine. The rotating mechanism drives the glass bottle to rotate and cooperates with the polishing component to make full use of the temperature of the glass bottle after the forming station, reduce the consumption of the polishing component, and at the same time cool the bottom of the formed bottle through the bottom cooling component, so as to achieve polishing while cooling the bottom of the glass bottle.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: the bottom cooling and polishing mechanism of the bottle making machine includes a bottom cooling component, a polishing component, a drive bracket, a drive gear, a driven gear and a drive device.

The bottom cooling component is arranged on the lower side of the driven gear and is rotatably connected to the driven gear. Both the bottom cooling component and the driven gear are provided with connecting pipes. The polishing component is arranged on the side of the bottom cooling component.

[0005] Preferably, the bottom cooling assembly includes a bottom cooling base and bottom cooling pipes. A mounting plate is provided on the upper side of the drive bracket. The bottom cooling base is disposed between the mounting plate and the driven gear, and the bottom cooling base and the driven gear are rotatably connected.

A first connecting pipe is provided on the bottom cooling base, and a second connecting pipe is provided on the driven gear. The bottom cooling pipes pass through the through hole and communicate with the first connecting pipe and the second connecting pipe.

[0006] Preferably, the mounting plate has two adjustment holes, and the bolts pass through the bottom cooling seat and are set in the two adjustment holes.

[0007] Preferably, it also includes a coupling and a reducer. The upper end of the coupling passes through the mounting plate and is connected to the drive gear, and the lower end is connected to the reducer fixed on the lower side of the mounting plate.

Detailed Implementation

[0025] Figures 1-3 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-8 The present invention will be further described below.

[0026] Example 1: Reference Figures 1-3In this embodiment, the bottom cooling and polishing mechanism is directly set between the molding station and the conveying station via the frame 15. The bottom cooling and polishing mechanism for the bottle making machine includes a bottom cooling component, a polishing component, and a rotating mechanism. The rotating mechanism includes a drive bracket 3, a drive gear 7, a driven gear 8, and a drive device 4. The drive bracket 3 is connected to the frame 15 via a mounting bracket 2. The drive gear 7 and the driven gear 8 are meshed and set on the upper side of the drive bracket 3. The drive gear 7 is connected to the drive device 4 set on the lower side of the drive bracket 3. The bottom mold 1 is set on the upper side of the driven gear 8. The upper end of the bottom cooling component is rotatably connected to the driven gear 8, and the lower end is fixedly connected to the drive bracket 3. The bottom mold 1, the driven gear 8, and the bottom cooling component are provided with a through pipe. The bottom mold 1 is also provided with an air outlet 102. The through pipe connects to the air outlet 102. The polishing component is set on the side of the bottom mold 1. The lifting mechanism is set on the lower side of the drive bracket 3. The drive device 4 is a motor or other device that can achieve this function.

[0027] In this embodiment, the mounting bracket 2 is a horizontally arranged rectangular frame. The drive bracket 3 is slidably disposed between the mounting bracket 2 and the frame 15. The mounting bracket 2 has a clearance groove on the side near the drive bracket 3 for the drive bracket 3 to pass through. A horizontal mounting plate 301 is provided on the upper side of the drive bracket 3. The driving gear 7 and the driven gear 8 are arranged side by side and meshed on the upper side of the mounting plate 301. The mounting plate 301 has two corresponding through holes. The through hole corresponding to the driving gear 7 allows the coupling 6 to pass through, and the coupling 6 is connected to the driving gear 7. A support bracket is provided between the driving gear 7 and the mounting plate 301. The support bracket supports the driving gear 7, and the driving gear 7 and the support bracket are connected by a ball bearing 12.

[0028] The coupling 6 is connected to the reducer 5 located on the lower side of the mounting plate 301. The reducer 5 is fixed to the lower end face of the mounting plate 301 by bolts. The other end of the reducer 5 is connected to the drive device 4. The drive device 4 drives the drive gear 7 to rotate, thereby driving the driven gear 8 to rotate.

[0029] The bottom cooling assembly includes a bottom cooling base 9 and bottom cooling pipes 10. The bottom cooling base 9 is bolted onto the mounting plate 301. The bottom cooling base 9 is an I-shaped support with a protruding boss on its lower end that mates with a through hole in the mounting plate 301. The mounting plate 301 has two elongated adjustment holes 303. Bolts pass through the bottom cooling base 9 and are positioned within the adjustment holes 303, thereby fixing the bottom cooling base 9 to the mounting plate 301. For different glass bottles, the front-to-back distance of the bottom cooling base 9 can be adjusted via the adjustment holes 303; this distance refers to the distance from the mounting bracket 2.

[0030] The upper end face of the bottom cooling base 9 is connected to the driven gear 8 via a thrust bearing 11. The driven gear 8 is fixed on the stop block 23, and the stop block 23 contacts the bottom of the upper end face, thereby fixing the thrust bearing 11. The driven gear 8 rotates on its own at the upper end of the bottom cooling base 9, which drives the bottom mold 1 set on the upper side of the driven gear 8 to rotate, thus causing the glass bottle to rotate.

[0031] The polishing assembly includes a polishing bracket 20, a spray gun 21, and a polishing pipeline 22. The polishing bracket 20 is mounted on the mounting bracket 2 by bolts. The spray gun 21 is located at the upper end of the polishing bracket 20. The polishing pipeline 22 is divided into an oxygen pipeline and a gas pipeline, both of which are connected to the spray gun 21. The nozzle of the spray gun 21 is vertically positioned facing the bottle body. When the glass bottle rotates, the spray gun 21 sprays out a flame to polish the bottle body.

[0032] The bottom cooling base 9 is provided with a first connecting pipe. The driven gear 8 has a through hole in the middle to form a second connecting pipe. The bottom mold 1 has a protrusion protruding downwards at its lower end, which is located in the through hole. The bottom mold 1 has a third connecting pipe that passes through the protrusion and is inclined outwards at the protrusion. The lower diameter of the third connecting pipe is larger than the upper diameter. The connector of the bottom cooling pipe 10 is connected to the lower end of the first connecting pipe. The upper end of the first connecting pipe is connected to the second and third connecting pipes in sequence. The other end of the bottom cooling pipe 10 is connected to a compressed air source through a control valve.

[0033] In this embodiment, the air outlet 102 of the bottom mold 1 is located at the center of the bottom mold 1, directly facing the bottom of the glass bottle. The glass bottle is placed on the upper surface of the bottom mold 1, which is hollowed out. The air outlet 102 is directly connected to the first connecting pipe. Cooling gas passes through the bottom cooling pipe 10, the first connecting pipe, the second connecting pipe and the third connecting pipe and is blown from the air outlet 102 to the bottom of the glass bottle, which can directly cool the bottom of the bottle.

[0034] The bottom cooling pipe 10 is a flexible hose, which is connected to the intermediate transition pipe through the switch valve 17. The intermediate transition pipe is connected to the compressed air source through the pressure regulating valve 16. The appropriate cooling air flow rate is adjusted by the pressure regulating valve 16. After the switch valve 17 is opened, the cooling air can cool the bottom mold 1.

[0035] The lower side of the drive bracket 3 is provided with a vertical adjustment block 302. The lifting mechanism includes a fixed frame, a vertically arranged lead screw 14, a handle 13, and two meshing helical gears (not shown in the figure). The two helical gears are set in the fixed frame. The handle 13 passes through the fixed frame and is connected to one of the helical gears. The handle 13 drives the helical gear to rotate, thereby driving the lead screw 14 connected to the other helical gear to rotate. The adjustment block 302 is provided with a threaded hole. The upper end of the lead screw 14 is set in the threaded hole. When the lead screw 14 rotates, the adjustment block 302 spirals up or down along the lead screw 14 to realize the height adjustment of the drive bracket 3.

[0036] Work process: Adjust the height of the bottom mold 1 by rotating handle 13 according to the height of the glass bottle being produced, so as to match the height of the glass bottle. When the glass bottle moves from the previous station to the bottom mold 1, the cooling air passes through the bottom cooling base 9, the driven gear 8 and the bottom mold 1 in sequence from the bottom cooling pipe 10, and then blows only onto the bottom of the glass bottle from the air outlet 102 to cool the bottom of the bottle. At the same time, the drive device 4 drives the drive gear 7 and the driven gear 8 to rotate, thereby causing the glass bottle placed on the bottom mold 1 to rotate, turning on the spray gun 21 to polish the glass bottle body.

[0037] Example 2: Reference Figures 4-5 The difference between this embodiment and embodiment 1 is that the structure of the mounting bracket 2 is different. In this embodiment, the mounting bracket 2 has a horizontally extended hanging plate on its upper side. The bottom cooling component and the polishing component can be directly hung between the servo bottle clamping mechanism 18 and the positive blowing mechanism 19 through the hanging plate, which is suitable for the transformation of traditional bottle making machines.

[0038] Example 3: Reference Figure 6 The difference between this embodiment and embodiment 1 is that the structure of the bottom mold 1 is different. The bottom mold 1 in this embodiment is provided with a bottom cooling cavity 101 inside, and the air outlet 102 is set on the side wall of the bottom mold 1. The first channel connects to the bottom cooling cavity 101. After the cooling gas enters the bottom cooling cavity 101, it flows out from the air outlet 102. The cooling gas cools the bottom mold 1 and indirectly cools the bottom of the glass bottle. It is suitable for situations where there is no need for drastic cooling to form the bottom of the bottle.

[0039] Example 4: Reference Figure 7 The difference between this embodiment and Embodiment 1 is that this embodiment is applicable to a double-drop bottle-making machine. Compared to the single-drop bottle-making machine in Embodiment 1, two bottom molds 1, driven gears 8, and bottom cooling seats 9 need to be set accordingly. The bottom cooling seats 9 are arranged side by side on the mounting plate 301. Two bottom cooling pipes 10 can be set and connected to the bottom cooling seats 9 respectively, or the upper end of a single bottom cooling pipe 10 can be forked with two connectors, and the two connectors can be inserted into the third channel of the bottom cooling seat 9 respectively. The two driven gears 8 mesh with each other, and one driven gear 8 meshes with the driving gear 7, thereby driving the two glass bottles placed on the bottom mold 1 to rotate respectively. Two corresponding polishing components are set. Two polishing brackets 20 can be set at intervals on the mounting bracket 2. Each polishing bracket 20 has a corresponding spray gun 21 at its upper end. The spray guns 21 are set in opposite directions and are set directly towards the body of their respective glass bottles.

[0040] Example 5: Reference Figure 8The difference between this embodiment and Embodiment 1 is that the lifting mechanism is mounted on the mounting bracket 2, and the lifting mechanism includes a lead screw 14 that is threadedly connected to the mounting plate 301. The mounting plate 301 has two threaded holes at both ends, the upper ends of the two lead screws 14 pass through the threaded holes, and the lower ends are connected to the mounting bracket 2. The lower ends of the lead screws 14 are rotatably connected to the mounting bracket 2. By rotating the lead screws 14, the lead screws 14 drive the mounting plate 301 to move in the height direction.

[0041] Example 6: The difference between this embodiment and embodiment 1 is that the rotating mechanism in this embodiment is set on the air duct, while the bottom cooling and polishing mechanism is located between the stop plate and the conveyor belt.

[0042] The bottom cooling base 9 is mounted on the air duct, which has a through hole connected to the first connecting pipe. The driven gear 8 is positioned between the bottom cooling base 9 and the bottom mold 1. The driving gear 7 meshes with the driven gear 8. The drive device 4, which drives the driving gear 7 to rotate, is located beside the air duct. The cooling air in the air duct is directly blown to the bottom of the glass bottle through the bottom cooling base 9 and the bottom mold 1. No additional lifting device is required; the bottom mold 1 is raised and lowered by the front bottle conveyor.

[0043] The polishing mechanism is also located on the side of the air duct, spaced apart from the drive device 4, to perform fire polishing on the bottle body.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
