[0002] A bottle making machine is a mechanical device used to manufacture glass bottles. Glass in a molten state is formed into glass bottles within a mold. In particular, initial mold side molds such as the initial mold, mouth mold, funnel, and air puff head need to be brushed with a release agent or lubricating oil.

Detailed Embodiment

[0023] Figures 1 - 3 This is the best embodiment of the present utility model. The following further describes the present utility model in conjunction with the attached Figures 1 - 3 drawings.

[0024] Such as Figure 1As shown in the figure, a primary mold spraying mechanism for a bottle making machine (hereinafter referred to as the spraying mechanism) includes an upper fixing table 3 and a lower fixing table 16 arranged at intervals up and down. A connecting plate 4 is arranged on the same side of the upper fixing table 3 and the lower fixing table 16, and the upper fixing table 3 and the lower fixing table 16 are fixed together through the connecting plate 4. A cylinder shaft 2 and a fixed shaft 1 are fixedly arranged side by side between the upper fixing table 3 and the lower fixing table 16, and the fixed shaft 1 is located outside the cylinder shaft 2. A piston cylinder is sleeved outside the cylinder shaft 2, and the piston cylinder moves up and down and rotates along the cylinder shaft 2.

[0025] The piston cylinder is coaxially butted up and down in sequence by an upper cylinder body 6, a middle cylinder body 12 and a lower cylinder body 15. A piston disk 9 is fixed in the middle of the cylinder shaft 2. A lower driving air path 20 and an upper driving air path 13 are axially opened from the bottom of the cylinder shaft 2. The lower driving air path 20 extends upward to the piston disk 9 and is located below the piston disk 9; the upper driving air path 13 extends upward to the piston disk 9 and is located above the piston disk 9. The middle cylinder body 12 of the piston cylinder is sleeved outside the piston disk 9, and the outer wall of the piston disk 9 is hermetically connected with the inner wall of the middle cylinder body 12. When compressed air is introduced through the lower driving air path 20, the compressed air drives the piston cylinder to move upward. Similarly, when compressed air is introduced through the upper driving air path 13, the compressed air drives the piston cylinder to move downward. Buffer springs are respectively arranged on the upper part and the lower part of the piston disk 9 to buffer the piston cylinder.

[0026] A switching valve 19 is arranged in the lower fixing table 16. The switching valve 19 is realized by a two-position five-way pneumatic control valve commonly used in the art. One end of a signal air pipe 18 is connected to the outside of this spraying mechanism through a signal air joint 17, and the other end of the signal air pipe 18 is connected to the signal air connection end of the switching valve 19. By introducing signal air into the switching valve 19, the action of the switching valve 19 is realized.

[0027] One end of a power air pipe 10 for sending power air is connected to the power air inlet of the switching valve 19. A main air supply pipe 11 is arranged outside this spraying mechanism, and a power air interface 8 is installed on the side of the main air supply pipe 11. One end of the power air pipe 10 is connected to the power air interface 8. Two air paths are opened in the lower fixing table 16. One ends of the two air paths are respectively connected to the lower driving air path 20 and the upper driving air path 13, and one ends of the two air paths are respectively connected to two air outlets of the switching valve 19. When the signal air sent through the signal air pipe 18 drives the switching valve 19 to act, the power air output by the switching valve 19 is respectively sent into the lower driving air path 20 and the upper driving air path 13 to further drive the piston cylinder to move upward or downward.

[0028] Combined Figure 2 , through holes 29 are respectively opened on the upper fixing table 3 and the lower fixing table 16. The upper end and the lower end of the above-mentioned fixed shaft 1 respectively pass through the through holes 29 on the upper fixing table 3 and the lower fixing table 16 and then are fixed, so the fixed shaft 1 can slide along the two through holes 29 up and down.

[0029] Outside the piston cylinder, a swing shaft 28 is also sleeved. The swing shaft 28 is clamped between the upper cylinder block 6 and the lower cylinder block 15. The side part of the swing shaft 28 extends radially to the outside of the fixed shaft 1, and the fixed shaft 1 passes through the swing shaft 28, and the fixed shaft 1 is movably connected to the swing shaft 28. A guide shaft 27 is also fixed between the upper and lower ends of the swing shaft 28, and the guide shaft 27 is parallel to both the cylinder shaft 2 and the fixed shaft 1 at the same time.

[0030] Combined Figure 3 , a limit block 33 is installed on the fixed shaft 1. The guide shaft 27 and the fixed shaft 1 respectively pass through the limit block 33, and the limit block 33 is fixedly connected to the fixed shaft 1 and movably connected to the guide shaft 27. The limit block 33 is detachably connected to the guide shaft 1 through a locking handle 32 on its side. The locking handle 32 can adopt an eccentric structure to achieve locking or unlocking with the fixed shaft 1, so as to realize the fixation and release of the limit block 33 and the fixed shaft 1. When unlocked from the fixed shaft 1 through the locking handle 32, the limit block 33 can move up and down along the axial directions of the fixed shaft 1 and the guide shaft 27 to adjust its height.

[0031] An oil injection arm 24 is also arranged outside the guide shaft 27. The guide shaft 27 and the fixed shaft 1 pass through the oil injection arm 24 at the same time. The oil injection arm 24 is fixedly connected to the guide shaft 27 through a locking bolt radially penetrating through its side part, and the oil injection arm 24 is movably connected to the fixed shaft 1.

[0032] An oil injection pipeline 26 is arranged in the oil injection arm 24. An oil injection valve 29 and a check valve 23 are respectively arranged at both ends of the oil injection arm 24. The oil injection valve 29 and the check valve 23 are respectively located at the inlet and outlet of the oil injection pipeline 26. A throttle valve 25 is also arranged in the middle of the oil injection arm 24. A nozzle 22 is vertically arranged at the end of the oil injection arm 24, and the nozzle 22 is butted against the outlet of the oil injection pipeline 26.

[0033] A valve cavity penetrating the upper and lower surfaces of the oil injection arm 24 is arranged in the oil injection arm 24. The oil injection valve 29 is placed in this valve cavity, and the inlet of the oil injection pipeline 26 is communicated with the valve cavity at the same time. The oil injection valve 29 includes an oil injection valve spring 31 and a valve body 35 sequentially placed in the valve cavity. The bottom of the valve body 35 is a driving end 34. One end of the external oil supply pipe 14 is connected into the valve cavity, and the other end extends to the oil supply port 7 and is butted against the oil supply port 7. When the oil injection valve spring 31 is not under external force, it pushes the valve body 35 to be at the lower end. At this time, the driving end 34 protrudes from the bottom of the oil injection arm 24, and at the same time, the valve body 35 is stuck in the valve cavity and blocks the oil injection pipeline 26 at the same time. When an external force pushes the driving end 34 to rise, the valve body 35 communicates the valve cavity with the oil injection pipeline 26 and compresses the oil injection valve spring 31, as Figure 3The state shown in the figure. At this time, the oil (release agent or lubricating oil) fed from the oil supply port 7 passes through the oil injection pipeline 26 and enters the nozzle 22, and is sprayed on the inner wall of the preform mold 21 by the nozzle 22.

[0034] The specific working process and working principle are as follows: When it is necessary to apply oil to the inner wall of the preform mold 21, the switching valve 19 is actuated by the signal gas in the signal gas joint 17. The power gas fed from the power gas pipeline 10 passes through the switching valve 19 and enters the lower drive gas path 20, and the piston cylinder is driven to descend by the power gas. A chute is provided on the inner wall of the upper cylinder body 6 of the piston cylinder, and at the same time, a cam mechanism 5 is provided on the surface of the cylinder shaft 2, and the cam mechanism 5 is clamped in the chute.

[0035] The front section of the chute is an inclined chute. When the piston cylinder descends along the cylinder shaft 2, under the action of the inclined chute and the cam mechanism 5, the movement of the piston cylinder is a combined movement of descending and rotating. At the same time, when the swing shaft 28 descends along the fixed shaft 1, it pushes the fixed shaft 1 to rotate along the guide groove 30. At the same time, when the swing shaft 28 drives the oil injection arm 24 to descend along the fixed shaft 1 through the guide shaft, it swings at the same angle as the fixed shaft 1. When the fixed shaft 1 rotates to the end of the guide shaft 30, the front section of the chute ends. At this time, the nozzle 22 at the end of the oil injection arm 24 is directly opposite to the upper port of the preform mold 21.

[0036] The rear section of the chute is a vertical section. At this time, the piston cylinder moves vertically downward along the axis of the cylinder shaft 2, and the swing shaft 28, the guide shaft 27, and the oil injection arm 24 descend synchronously. When the oil injection arm 24 descends to the limit block 33, the piston cylinder descends to the lowest position. At this time, the nozzle 22 enters the preform mold 21.

[0037] And when the oil injection arm 24 fits with the limit block 33, the push drive end 34 is raised through the limit block 33. At this time, the valve body 35 rises to connect the valve cavity with the oil injection pipeline 26, and at the same time, the oil injection valve spring 31 is compressed. At this time, the oil (release agent or lubricating oil) fed from the oil supply port 7 passes through the oil injection pipeline 26 and enters the nozzle 22, and is sprayed on the inner wall of the preform mold 21 by the nozzle 22. Therefore, the limit block 33 not only limits the descending position of the oil injection arm 24, but also serves to open the oil injection valve 29.

[0038] After reaching the predetermined oil injection time, the signal gas in the signal gas pipeline 18 is withdrawn, the switching valve 19 acts, and the power gas fed from the power gas pipeline 10 passes through the switching valve 19 and enters the upper drive gas path 13, and the piston cylinder is driven to ascend by the power gas. During the ascending process of the piston cylinder, under the combined action of the chute and the cam mechanism 5 in the upper cylinder body 6, it first ascends vertically until the nozzle 22 is transferred outside the preform mold 21. At this time, since the oil injection arm 24 has been separated from the limit block 31, the oil injection valve 29 is closed.

[0039] Then the piston cylinder performs a combined motion of upward movement and rotation. At the same time, when the swing shaft 28 moves upward along the fixed shaft 1, the fixed shaft 1 is driven to rotate reversely along the guide groove 30. At the same time, the fuel injection arm 24 is driven by the swing shaft 28 to perform a combined motion of upward movement and rotation until the fixed shaft 1 rotates to the other end of the guide groove 30, completing a complete fuel injection process, and so on.

Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes.
