[0002] The bottle blowing device includes a rotating body and a bottle blowing mechanism installed on the rotating body. The rotating body can drive the bottle blowing mechanism to rotate.

[0040] The present application provides a bottle blowing device, comprising a rotating body, a bottle blowing mechanism and an automatic oiling mechanism, wherein the rotating body can rotate around its axis, the bottle blowing mechanism is installed on the outer periphery of the rotating body, and the automatic oiling mechanism is installed on the rotating body and is used to add lubricating oil to the bottle blowing mechanism to extend the service life of the bottle blowing mechanism.

[0041] It should be noted that the rotating body and bottle blowing mechanism provided in the present application can be selected from the rotating body and bottle blowing mechanism in the prior art, and the rotating body and bottle blowing mechanism belong to conventional technologies in the field of bottle blowing, which will not be described in detail here.

[0042] Figure 1 The structure diagram of the automatic refueling mechanism provided in the embodiment of the present application is shown. Figure 1 As shown, the automatic refueling mechanism includes an oil storage barrel 1 and a centrifugal pump 2, wherein the oil storage barrel 1 is used to contain lubricating oil and is installed at the center of the rotating body; the centrifugal pump 2 includes a shell 21 and a centrifugal assembly 22, the shell 21 has a receiving cavity and an oil inlet interface 2101 and an oil outlet interface 2102 connected to the receiving cavity, the oil inlet interface 2101 is located at one end of the shell 21 close to the oil storage barrel 1, and the oil inlet interface 2101 is connected to the oil outlet 111 of the oil storage barrel 1 through a first pipeline 3; the oil outlet interface 2102 is located at the shell 21 The body 21 is away from one end of the oil storage barrel 1, and the oil outlet interface 2102 is connected to the refueling position of the bottle blowing mechanism through the second pipeline 4; the centrifugal component 22 can move relative to the shell 21 along the radial direction of the rotating body; when the rotating body is rotating, the centrifugal component 22 can push the lubricating oil in the accommodating cavity to the oil outlet interface 2102, and make the lubricating oil entering the second pipeline 4 flow to the refueling position of the bottle blowing mechanism, thereby realizing automatic refueling, which can not only reduce the labor intensity of workers, but also avoid the occurrence of oil leakage and extend the service life of the equipment.

[0043] The automatic refueling mechanism further comprises a control valve 5 . The second pipeline 4 is provided with a control valve 5 . The control valve 5 can adjust the refueling flow rate.

[0044] Figure 2A cross-sectional schematic diagram of a centrifugal pump 2 provided in an embodiment of the present application is shown. Figure 3 FIG. 2 shows an exploded schematic diagram of a centrifugal pump 2 provided in an embodiment of the present application. Figures 2 to 3 As shown, the centrifugal assembly 22 includes a push rod 221, an elastic member 223 and a weighted centrifugal member 222. The first end of the push rod 221 is slidably matched with the inner wall of the accommodating chamber of the housing 21. The second end of the push rod 221 extends out of the housing 21 and is connected to the weighted centrifugal member 222. The elastic member 223 is located between the first end of the push rod 221 and the inner wall of the accommodating chamber and is used to restore the push rod 221 to its original position. When the rotating body rotates, the weighted centrifugal member 222 generates a centrifugal force, and the weighted centrifugal member 222 drives the push rod 221 and compresses the elastic member 223 to move in the direction of the oil outlet interface 2102, thereby pushing the lubricating oil in the accommodating chamber to the oil outlet interface 2102, so that the lubricating oil flows from the oil outlet interface 2102 into the second pipeline 4. Thereafter, the lubricating oil can flow to the refueling position of the bottle blowing mechanism under the action of its own gravity, thereby realizing automatic refueling. When the rotating body stops rotating, the centrifugal force of the counterweight centrifugal member 222 disappears, and the push rod 221 returns to its original position under the action of the elastic member 223, that is, the automatic refueling stops. It should be noted that the counterweight centrifugal member 222 can select a counterweight member of appropriate weight according to actual conditions. In addition, during the rotation of the rotating body, not only the counterweight centrifugal member 222 and the push rod 221 will generate centrifugal force, but also the oil storage barrel 1, the first pipeline 3 and the lubricating oil in the accommodating chamber will generate a certain centrifugal force, which is conducive to the flow of the lubricating oil to the direction of the oil outlet interface 2102.

[0045] The first end of the push rod 221 slides with the inner wall of the accommodating chamber and divides the accommodating chamber into a first chamber 2103 and a second chamber 2104. The first chamber 2103 and the second chamber 2104 are in a connected state and a blocked state, and the first chamber 2103 is connected to the oil inlet interface 2101, and the second chamber 2104 is connected to the oil outlet interface 2102.

[0046] It can be understood that the oil storage barrel 1 is connected to the first chamber 2103 through the first pipeline 3. Under the action of the pressure difference, the lubricating oil in the oil storage barrel 1 will flow toward the direction of the accommodating chamber of the shell 21, and the lubricating oil will flow into the first chamber 2103 through the oil inlet interface 2101 of the shell 21. When the lubricating oil in the first chamber 2103 accumulates to a certain amount, the lubricating oil in the first chamber 2103 can flow into the second chamber 2104. When the rotary body rotates, the push rod 221 moves in the direction of compressing the space of the second chamber 2104 under the centrifugal action of the counterweight centrifugal member 222, and makes the lubricating oil in the second chamber 2104 flow from the oil outlet interface 2102 into the second pipeline 4, and finally flows to the refueling position of the bottle blowing mechanism. When the rotating body stops rotating, the push rod 221 moves in the direction of compressing the first chamber 2103 under the action of the elastic member 223 . The pressure of the first chamber 2103 is greater than the pressure of the second chamber 2104 , so that the lubricating oil in the first chamber 2103 flows into the second chamber 2104 .

[0047] In this embodiment, the push rod 221 includes a sliding portion 2211 and a rod portion 2212 connected to the sliding portion 2211, the sliding portion 2211 is slidably matched with the inner wall of the accommodating chamber, the rod portion 2212 extends along the radial direction of the rotating body, and one end of the rod portion 2212 extends out of the housing 21 and is connected to the counterweight centrifugal member 222. Such a configuration can facilitate the push rod 221 to slide with the inner wall of the accommodating chamber, and can also facilitate the connection between the push rod 221 and the counterweight centrifugal member 222.

[0048] Furthermore, the diameter of the sliding portion 2211 of the push rod 221 is greater than the diameter of the rod portion 2212 , so as to reduce the space occupied by the rod portion 2212 in the second cavity 2104 and increase the oil capacity of the second cavity 2104 .

[0049] In order to facilitate the installation of the elastic member 223, an end of the accommodating cavity away from the oil inlet interface 2101 has an abutting surface, and the elastic member 223 extends along the movement direction of the push rod 221 and is located between the sliding portion 2211 and the abutting surface. For example, the elastic member 223 can be a spring, which is sleeved outside the rod portion 2212 of the push rod 221, and can guide and position the elastic member 223 to ensure the smooth movement of the push rod 221.

[0050] The centrifugal assembly 22 also includes a first baffle 224, the sliding portion 2211 has a first through hole 22111 extending through the thickness thereof, one end of the first baffle 224 is fixed to the side of the sliding portion 2211 away from the oil outlet interface 2102, and the other end of the first baffle 224 covers the first through hole 22111, and the first baffle 224 can be deformed and has a blocking state of blocking the first through hole 22111 and a closing state of opening the first through hole 22111. In other words, the first baffle 224 is similar to a spring structure. When the push rod 221 moves toward the oil outlet interface 2102, the pressure in the first chamber 2103 is less than the pressure in the second chamber 2104. The first baffle 224 blocks the first through hole 22111 under the pressure in the second chamber 2104, thereby preventing the lubricating oil in the first chamber 2103 from flowing into the second chamber 2104 indefinitely and avoiding excessive refueling to cause waste. When the push rod 221 moves toward the oil inlet interface 2101, the pressure in the first chamber 2103 is greater than the pressure in the second chamber 2104. The first baffle 224 is deformed in the direction away from the first through hole 22111 under the pressure in the first chamber 2103, thereby keeping the first through hole 22111 in a smooth state. At this time, the lubricating oil in the first chamber 2103 can flow into the second chamber 2104 through the first through hole 22111.

[0051] In this embodiment, the number of the first through holes 22111 is four, and the four first through holes 22111 are arranged at intervals along the circumference of the sliding portion 2211, and each first through hole 22111 is configured with a first blocking piece 224. In other embodiments, the number of the first through holes 22111 can also be any number such as two, three, four, or five, and the multiple first through holes 22111 are arranged at intervals along the circumference of the sliding portion 2211, and each first through hole 22111 is configured with a first blocking piece 224.

[0052] In order to facilitate the assembly of the centrifugal pump 2, the housing 21 includes a housing body 211 and an end cover 212. The housing body 211 has a first opening 2111 and a second opening 2112 at both ends of its length direction. The end cover 212 is detachably sealed to the first opening 2111. The rod 2212 extends from the second opening 2112 and is slidably sealed with the second opening 2112. In order to improve the sealing performance of the matching position of the rod 2212 and the housing 21, the centrifugal pump 2 also includes a first sealing member 225, which is located between the rod 2212 and the inner wall of the second opening 2112.

[0053] Furthermore, one end of the first opening 2111 of the shell body 211 has a mounting flange 2113, and the end cover 212 is detachably fixed to the mounting flange 2113 by a fastener. In addition, in order to improve the sealing between the end cover 212 and the shell body 211, the centrifugal pump 2 further includes a second sealing member 226, and the second sealing member 226 is located between the end cover 212 and the mounting flange 2113.

[0054] In this embodiment, the shell body 211 includes a cylindrical portion and a tapered portion, the sliding portion 2211 is slidably matched with the inner wall of the cylindrical portion, the end of the cylindrical portion away from the tapered portion is provided with a first opening 2111, and the end of the tapered portion away from the cylindrical portion is provided with a second opening 2112. This design can facilitate the sliding portion 2211 of the push rod 221 to slide with the inner wall of the accommodating cavity, and can also limit the movement stroke of the push rod 221 through the tapered portion.

[0055] Figure 4 FIG. 1 shows an exploded schematic diagram of an oil storage barrel 1 provided in an embodiment of the present application. Figure 4 Combination Figure 1 As shown, the oil storage barrel 1 includes a barrel body 11, a barrel cover 12 and a second baffle 13. The upper end of the barrel body 11 has an opening, the lower end of the barrel body 11 has an oil outlet 111, the barrel cover 12 sealing cover is arranged at the opening, the barrel cover 12 has a second through hole 121 running through its thickness direction, one end of the second baffle 13 is fixed to the side of the barrel cover 12 located inside the barrel body 11, and the other end of the second baffle 13 covers the second through hole 121, and the second baffle 13 can be deformed and has a blocking state of blocking the second through hole 121 and a closed state of opening the second through hole 121. When the barrel cover 12 is covered on the barrel body 11, the second baffle 13 can achieve sealing of the barrel body 11 to prevent foreign debris from falling into the barrel body 11; when it is necessary to add lubricating oil to the barrel body 11, the second baffle 13 can prevent the barrel cover 12 from being unable to be opened due to the pressure difference between the inside and outside of the barrel body 11.

[0056] It should be noted that, in this embodiment, an oil outlet 111 is provided at the lower end of the barrel body 11, and similarly, the first pipeline 3, the centrifugal pump 2, the second pipeline 4 and other components are also a group.
