Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] The preliminary cleaning mechanism of the present invention, such as Figure 1 As shown, it includes a first lifting frame 31, which is connected to a first lifting mechanism 32. The first lifting mechanism 32 can be a common device such as a cylinder. A vertical cleaning shaft 33 is provided at the top of the first lifting frame 31. The cleaning shaft 33 is rotatably mounted on the first lifting frame 31. A cleaning motor 34 is connected to the lower end of the cleaning shaft 33, which can drive the cleaning shaft 33 to rotate.

[0031] The upper outer wall of the cleaning shaft 33 is provided with a stirring plate 35. The stirring plate 35 can be a rectangular plate or a spiral plate. When the cleaning shaft 33 rotates, it can drive the stirring plate 35 to rotate.

[0032] The top of the first lifting frame 31 is provided with a storage tank 36, which is cylindrical in shape. Its lower end is connected to the first lifting frame 31 and sealed by the first lifting frame 31. The upper end of the storage tank 36 is open, and the inner diameter of the storage tank 36 is adapted to the inner diameter of the glass bottle to be cleaned. Specifically, the inner diameter of the storage tank 36 is the same as the inner diameter of the bottle mouth to be cleaned, ensuring that the upper end of the storage tank 36 can be aligned with the bottle mouth.

[0033] The cleaning shaft 33 is located within and coaxial with the storage tank 36. The bottom of the storage tank 36 has an inlet and a outlet. The inlet is connected to a first cleaning fluid supply mechanism, which pressurizes the cleaning fluid and introduces it into the storage tank 36. The outlet is connected to a drain valve 39, which drains the cleaning fluid from the storage tank 36. Both the inlet and outlet are equipped with filter screens 310. The storage tank 36 contains multiple elastic balls 311. The outer diameter of the elastic balls 311 is larger than the pore diameter of the filter screens 310, preventing the elastic balls 311 from moving out of the storage tank 36 through the inlet and outlet. The density of the elastic balls 311 matches the density of the cleaning fluid, allowing them to suspend in the cleaning fluid. The elastic balls 311 can be made of hollow plastic balls, rubber balls, or other commonly used materials with low hardness, ensuring they will not damage the glass bottle during collisions.

[0034] When the preliminary cleaning mechanism of this invention performs preliminary cleaning on the glass bottle, such as... Figure 2 As shown, the glass bottle is transported directly above the cleaning shaft 33, which is coaxial with the glass bottle, with the bottle opening facing downwards. Then, the first lifting mechanism 32 drives the first lifting frame 31 to move upwards, causing the cleaning shaft 33 to enter the glass bottle. At the same time, the upper port of the storage tank 36 is aligned with the bottle opening, and there is an exhaust gap between the upper port of the storage tank 36 and the bottle opening. The exhaust gap is used for air to enter and exit the glass bottle to ensure that the cleaning fluid is introduced into the glass bottle or discharged from the glass bottle. The width of the exhaust gap is smaller than the diameter of the elastic ball 311 to prevent the elastic ball 311 from being discharged from the exhaust gap.

[0035] Next, the first cleaning fluid supply mechanism continuously feeds the cleaning fluid into the storage tank 36. Some cleaning fluid is discharged through the venting gap, but the inflow rate is greater than the outflow rate, ensuring the cleaning fluid enters the glass bottle. Since the elastic ball 311 can be suspended in the cleaning fluid, it enters the glass bottle along with the fluid. At this time, the cleaning motor 34 drives the cleaning shaft 33 to rotate, which in turn drives the stirring plate 35. Under the action of the stirring plate 35, the elastic ball 311 moves irregularly, continuously striking the inner wall of the glass bottle, causing stubborn impurities attached to the inner wall to detach. The cleaning motor 34 can rotate forward and reverse alternately to improve the cleaning effect.

[0036] After cleaning is completed, the cleaning motor 34 stops running, the first cleaning fluid supply mechanism stops supplying cleaning fluid, and the drain valve 39 opens, allowing the cleaning fluid in the glass bottle to automatically drain through the vent gap. The elastic ball 311 inside the glass bottle returns to the storage tank 36, and the cleaning fluid in the storage tank 36 is drained through the drain valve 39. Finally, the first lifting mechanism 32 drives the first lifting frame 31 to move downwards, causing the cleaning shaft 33 to move outside the glass bottle, completing the initial cleaning.

[0037] In the present application, the elastic balls 311 are driven to move constantly by the stirring blades 35, so that the elastic balls 311 move irregularly, and under the action of centrifugal force, the elastic balls 311 constantly collide with the inner wall of the glass bottle, so that the stubborn impurities adhered to the inner wall of the glass bottle can be separated from the glass bottle, thereby improving the cleaning effect.

[0038] In the present application, the first cleaning liquid supply mechanism comprises a hose 312, a first water pump 313 and a cleaning liquid storage tank 314 connected in sequence, and the hose 312 is connected with the water inlet. The hose 312 can be a flexible pipe such as a rubber pipe. The cleaning liquid storage tank 314 stores cleaning liquid, and the first water pump 313 can drive the cleaning liquid in the cleaning liquid storage tank 314 to flow to the water inlet, so as to deliver the cleaning liquid to the storage tank 36.

[0039] In order to promote the cleaning liquid discharged from the storage tank 36 and the glass bottle to return to the cleaning liquid storage tank 314, a support 315 is arranged on the top of the cleaning liquid storage tank 314, and the first water pump 313 and the first lifting mechanism 32 are both installed on the support 315. The cleaning liquid storage tank 314 is located below the first lifting frame 31 and the like, and when cleaning, the discharged cleaning liquid can automatically flow downward into the cleaning liquid storage tank 314, realizing the repeated use of the cleaning liquid.

[0040] In order to improve the stability of the first lifting frame 31 during lifting, a vertical guide column 316 is arranged on the support 315, the guide column 316 penetrates through the first lifting frame 31 and is in sliding cooperation with the first lifting frame 31, and the guide column 316 can be multiple, which plays a role of guiding and positioning.

[0041] The glass bottle cleaning device of the present application comprises a rotating disc 1, a rotating driving mechanism, a plurality of horizontal suspension arms 2, a glass bottle positioning mechanism, an upper feeding station, a preliminary cleaning station, a re-cleaning station and a discharging station. Figures 3 to 8 As shown in the figure, the rotating disc 1 is a disc and is rotatably installed on a rack, and the rotating disc 1 is connected with a rotating driving mechanism which can adopt a speed reducer motor and can drive the rotating disc 1 to rotate. A plurality of horizontal suspension arms 2 are arranged at the edge of the rotating disc 1, the length direction of the suspension arms 2 is consistent with the radial direction of the rotating disc 1, and a glass bottle positioning mechanism is arranged at the end of the suspension arms 2 away from the rotating disc 1, which can position the glass bottle. An upper feeding station, a preliminary cleaning station, a re-cleaning station and a discharging station are sequentially arranged around the rotating disc 1 along the rotating direction thereof. The upper feeding station is used to move the glass bottle to the glass bottle positioning mechanism and position the glass bottle through the glass bottle positioning mechanism; the preliminary cleaning station is used to preliminarily clean the glass bottle; the re-cleaning station is used to re-clean the glass bottle; and the discharging station is used to take down the cleaned glass bottle from the glass bottle positioning mechanism. The upper feeding and discharging can be manually performed or by using a mechanical hand. The suspension arms 2 are at least 4, so that at the same time, the upper feeding station, the preliminary cleaning station, the re-cleaning station and the discharging station all have the suspension arms 2, and the upper feeding, the preliminary cleaning, the re-cleaning and the discharging are simultaneously performed.

[0042] As shown in Figure 4 , the preliminary cleaning station is provided with a preliminary cleaning mechanism as shown in Figure 1 .

[0043] In use, the rotating drive mechanism drives the rotating disc 1 to rotate by a specific angle and then stops, the rotating disc 1 drives each cantilever 2 to move to the feeding station, the preliminary cleaning station, the re-cleaning station and the unloading station in turn, at the feeding station, the glass bottle is fixed to the cantilever 2 through the glass bottle positioning mechanism; at the preliminary cleaning station, the preliminary cleaning mechanism performs preliminary cleaning on the glass bottle; at the re-cleaning station, the re-cleaning mechanism performs re-cleaning on the glass bottle; at the unloading station, the cleaned glass bottle is taken off.

[0044] It is known that impurities can be removed more effectively after soaking and then cleaning, in order to soak the glass bottle before preliminary cleaning, as shown in Figure 5 , a cleaning liquid injection head 41 is arranged above the feeding station, the cleaning liquid injection head 41 is connected with a second cleaning liquid supply mechanism. After the glass bottle is fixed to the glass bottle positioning mechanism, the bottle opening of the glass bottle faces upward, at this time, the second cleaning liquid supply mechanism can be used to deliver cleaning liquid to the cleaning liquid injection head 41, and the cleaning liquid injection head 41 injects the cleaning liquid into the glass bottle. The glass bottle is filled with cleaning liquid in advance, which can soak the glass bottle to improve the effect of subsequent cleaning. The second cleaning liquid supply mechanism can be the same as the first cleaning liquid supply mechanism, specifically, the cleaning liquid injection head 41 is connected with the hose 312 through a pipeline, and a control valve is arranged on the pipeline.

[0045] When soaking, the bottle opening of the glass bottle faces upward, but when preliminary cleaning and re-cleaning, the bottle opening of the glass bottle faces downward, therefore, the cantilever 2 includes a connecting arm 21 and a rotating arm 22, the connecting arm 21 is fixed on the rotating disc 1, one end of the rotating arm 22 extends into the connecting arm 21 and is rotatably installed on the connecting arm 21, and the rotating arm 22 is connected with an adjusting motor 23, and the glass bottle positioning mechanism is located at the end of the rotating arm 22 away from the connecting arm 21. When the rotating disc 1 drives the cantilever 2 to move to the preliminary cleaning station, the adjusting motor 23 drives the rotating arm 22 to rotate by 180°, so that the glass bottle rotates by 180°, and after rotation, the bottle opening of the glass bottle faces downward.

[0046] After re-cleaning, in order to promote the rapid drying of the glass bottle, a drying mechanism can be arranged, in order to reduce the number of equipment, the present application integrates the re-cleaning and drying in the same station, and realizes the working process of re-cleaning first and then drying. Specifically, as shown in Figure 5 , Figure 6 and Figure 7As shown, the re-washing station is provided with a re-washing and drying mechanism, which comprises a second lifting frame 51 connected with a second lifting mechanism 52, which can be a pneumatic cylinder. The top of the second lifting frame 51 is provided with a spray pipe 53 connected with a clean water supply mechanism and a gas supply mechanism. The second lifting frame 51, the second lifting mechanism 52 and other devices can be arranged below the water collecting pool, and the clean water after re-washing directly falls into the water collecting pool.

[0047] During re-washing, the cantilever 2 drives the glass bottle after preliminary cleaning to be above the spray pipe 53, the second lifting mechanism 52 drives the second lifting frame 51 to move upward, so that the spray pipe 53 extends into the glass bottle, then the clean water supply mechanism supplies clean water to the spray pipe 53, the clean water is sprayed from the spray pipe 53 to clean the inner wall of the glass bottle. After cleaning, the clean water supply mechanism stops water supply, the gas supply mechanism supplies high-pressure air to the spray pipe 53, and the high-pressure air is sprayed to the inner wall of the glass bottle to dry the inner wall of the glass bottle. After drying, the gas supply mechanism stops air supply, the second lifting mechanism 52 drives the second lifting frame 51 to move downward to the initial position, and the spray pipe 53 is separated from the glass bottle.

[0048] In order to further improve the re-washing effect, the spray pipe 53 is rotatably installed on the second lifting frame 51, the lower end of the spray pipe 53 is connected with a re-washing motor 54, and the re-washing motor 54 can drive the spray pipe 53 to rotate at high speed. The second lifting frame 51 is provided with a jacket 55, which is a circular sleeve with sealed upper and lower ends and is fixedly installed on the second lifting frame 51. The spray pipe 53 penetrates the jacket 55, and the side wall of the spray pipe 53 inside the jacket 55 is provided with a through hole 56, the lower end of the spray pipe 53 is sealed, and the inside has a central hole, and the through hole 56 can communicate the central hole of the spray pipe 53 with the inner cavity of the jacket 55.

[0049] The clean water supply mechanism comprises a clean water pipe 57 connected in sequence, the clean water pipe 57 is a flexible pipe which can be bent and straightened. A second water pump 58 and a clean water pool 59, the clean water pool 59 stores clean water, and the second water pump 58 can deliver the clean water in the clean water pool 59 to the clean water pipe 57. The gas supply mechanism comprises an air pipe 510 and an air compressor 511, the air pipe 510 is also a flexible pipe, and the air compressor 511 can deliver compressed air to the air pipe 510. The air pipe 510 communicates with the jacket 55 through a first valve 512, the first valve 512 is a one-way valve to prevent water from flowing along the air pipe 510 to the air compressor 511. The clean water pipe 57 communicates with the jacket 55 through a second valve 513, the air outlet direction of the first valve 512 is consistent with the radial direction of the jacket 55, and the water outlet direction of the second valve 513 is tangent to the jacket 55.

[0050] During the rinsing, the water supply mechanism and the air supply mechanism are operated simultaneously, the first valve 512 and the second valve 513 are both opened, the compressed air enters the jacket 55 through the first valve 512, and the flow direction of the air is consistent with the radial direction of the jacket 55; at the same time, the pressurized water enters the jacket 55 through the second valve 513, the flow direction of the water is perpendicular to the radial direction of the jacket 55, and the water makes a circular motion along the inner wall of the jacket 55, and the air is impacted and sheared by the water flow to form a large number of micro-bubbles. The water containing a large number of micro-bubbles enters the spray pipe 53 through the through hole 56.

[0051] As shown in Figure 6 and Figure 7 , the inside of the spray pipe 53 is provided with a central column 514 coaxial with the spray pipe 53, and the central column 514 and the inner wall of the spray pipe 53 are provided with helical guide vanes 515. After the water enters the spray pipe 53, it moves upward in a helical shape along the spray pipe 53, promoting the further mixing of the water and the air to generate a large number of micro-bubbles.

[0052] The top of the spray pipe 53 is provided with a vertical first outlet 516, and the sidewall of the top of the spray pipe 53 is provided with a plurality of second outlets 517, and each second outlet 517 is connected with a flexible water outlet pipe 518. Part of the water is sprayed out of the first outlet 516 to rinse the bottom of the glass bottle, and the remaining water enters the water outlet pipe 518 through the second outlet 517 and is then sprayed out of the water outlet pipe 518 to rinse the sidewall of the glass bottle.

[0053] Because the water contains a large number of micro-bubbles, the micro-bubbles produce cavitation effect when they burst, which can effectively remove stubborn impurities and fully wash away the remaining cleaning liquid, further improving the cleaning effect.

[0054] In addition, in the traditional high-pressure cleaning nozzle, a large part of the water collides with the glass bottle and then flows quickly downward after being sprayed toward the inner wall of the glass bottle, which consumes a large amount of water and has a flushing dead angle. In the present application, during the rinsing, the rinsing motor 54 drives the spray pipe 53 to rotate at a high speed, the spray pipe 53 drives the water outlet pipe 518 to rotate, the length of the water outlet pipe 518 is greater than the distance between the spray pipe 53 and the inner wall of the glass bottle, and under the action of centrifugal force, the water outlet pipe 518 will be in a horizontal state, and because the water outlet end of the water outlet pipe 518 is blocked by the inner wall of the glass bottle and is bent, the water outlet pipe 518 adheres to the inner wall of the glass bottle, and the water outlet direction of the water outlet pipe 518 is tangent to the inner wall of the glass bottle, as shown in Figure 8 , after the water is sprayed, it makes a circular motion along the inner wall of the glass bottle to form a rotational flow, which can flush the inner wall of the glass bottle in all directions without a dead angle, and in combination with the cavitation effect produced by the bursting of the micro-bubbles, the cleaning effect is effectively improved.

[0055] After rinsing, the second valve 513 can be closed, and the first valve 512 remains open, and high-pressure air is introduced into the glass bottle to dry the glass bottle.

[0056] In the present application, the glass bottle positioning mechanism can adopt various mechanisms capable of stably clamping columnar parts, such as a three-jaw chuck 24, and an elastic rubber pad can be arranged on the clamping surface of the clamping jaw to prevent the glass bottle from being clamped.

[0057] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Various modifications and changes can be made by those skilled in the art based on the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
