Description

TECHNICAL FIELD

[0002] At present, many seasonings and foods are packaged in glass bottles. Before formal packaging, the glass bottles must be cleaned to ensure food safety. The conventional cleaning method is to extend the cleaning nozzle into the glass bottle and use high-pressure water to flush the inside of the glass bottle, and then dry it. Some cleaning devices are also provided with brushes, such as the invention patent with the application number CN202311639185.6 discloses a cleaning device for food packaging bottles. During cleaning, a flexible brush is extended into the glass bottle to remove the dirt adhered to the inner wall of the glass bottle by the brush. However, since the diameter of the bottle mouth of the glass bottle is usually smaller than the diameter of the bottle body, the brush is easy to bend when entering and exiting the glass bottle, which makes it difficult for the brush to fully contact the inner wall of the glass bottle after entering the glass bottle. In addition, most of the packaging glass bottles have irregular shapes, and the cleaning effect of the brush may have certain dead angles, resulting in poor cleaning effect. Moreover, the brush is easy to break or the brush bundle is easy to fall off after being used for a period of time, and the broken or fallen brush bundle may adhere to the glass bottle, causing food safety accidents.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] 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.

[0016] 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.

[0017] 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.

[0018] The cleaning shaft 33 is located in the storage tank 36 and coaxial with the storage tank 36, the bottom of the storage tank 36 is provided with a water inlet and a drain, the water inlet is connected with a first cleaning liquid supply mechanism, the first cleaning liquid supply mechanism is used for pressurizing and feeding the cleaning liquid into the storage tank 36; the drain is connected with a drain valve 39, and the drain valve 39 can drain the cleaning liquid in the storage tank 36. The water inlet and the drain are both provided with a filter screen 310, and the storage tank 36 is provided with a plurality of elastic balls 311, the outer diameter of the elastic ball 311 is greater than the filter hole diameter of the filter screen 310, so that the elastic ball 311 cannot move out of the storage tank 36 through the water inlet and the drain, and the density of the elastic ball 311 is matched with the density of the cleaning liquid, so that the elastic ball 311 can be suspended in the cleaning liquid. The elastic ball 311 can be made of a hollow plastic ball, a rubber ball or other commonly used materials with low hardness, so as not to damage the glass bottle in the process of collision with the glass bottle.

[0019] When the primary cleaning mechanism of the present application performs primary cleaning on the glass bottle, as shown in the figure, the glass bottle is conveyed to the upper side of the cleaning shaft 33, the cleaning shaft 33 is coaxial with the glass bottle, and the mouth of the glass bottle faces downward. Figure 2 Then the first lifting mechanism 32 drives the first lifting frame 31 to move upward, so that the cleaning shaft 33 enters the glass bottle, and the upper end of the storage tank 36 is aligned with the mouth of the glass bottle, and there is an exhaust gap between the upper end of the storage tank 36 and the mouth of the glass bottle, which is used for air to enter and exit the glass bottle, so as to ensure that the cleaning liquid is fed into the glass bottle or the cleaning liquid in the glass bottle is drained, and the width of the exhaust gap is smaller than the diameter of the elastic ball 311, so as to prevent the elastic ball 311 from being discharged from the exhaust gap.

[0020] Then the first cleaning liquid supply mechanism continuously feeds the cleaning liquid into the storage tank 36, part of the cleaning liquid is discharged from the exhaust gap, but the flow rate of the cleaning liquid fed is greater than that of the cleaning liquid discharged from the exhaust gap, so as to ensure that the cleaning liquid can enter the glass bottle, and since the elastic ball 311 can be suspended in the cleaning liquid, the elastic ball 311 enters the glass bottle along with the cleaning liquid. At this time, the cleaning motor 34 drives the cleaning shaft 33 to rotate, the cleaning shaft 33 drives the stirring blade 35 to rotate, and under the action of the stirring blade 35, the elastic ball 311 moves irregularly and constantly knocks the inner wall of the glass bottle, so as to promote the stubborn impurities attached to the inner wall of the glass bottle to separate. The cleaning motor 34 can work alternately in forward and reverse directions, so as to improve the cleaning effect.

[0021] After the cleaning is completed, the cleaning motor 34 stops running, the first cleaning liquid supply mechanism stops providing the cleaning liquid, and the drain valve 39 is opened, so that the cleaning liquid in the glass bottle can be automatically discharged through the exhaust gap, the elastic ball 311 in the glass bottle returns to the storage tank 36, and the cleaning liquid in the storage tank 36 is discharged through the drain valve 39. Finally, the first lifting mechanism 32 drives the first lifting frame 31 to move downward, so that the cleaning shaft 33 moves out of the glass bottle, and the primary cleaning is completed.

[0022] 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.

[0023] 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.

[0024] 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, so as to realize the repeated use of the cleaning liquid.

[0025] 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 fit with the first lifting frame 31, and the guide column 316 can be multiple, which plays a role of guiding and positioning.

[0026] 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 for moving the glass bottle to the glass bottle positioning mechanism and positioning the glass bottle through the glass bottle positioning mechanism; the preliminary cleaning station is used for preliminarily cleaning the glass bottle; the re-cleaning station is used for re-cleaning the glass bottle; and the discharging station is used for taking 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 the upper feeding station, the preliminary cleaning station, the re-cleaning station and the discharging station all have the suspension arms 2 at the same time, and the upper feeding, the preliminary cleaning, the re-cleaning and the discharging are simultaneously performed.

[0027] like Figure 4 As shown, the preliminary cleaning station is equipped with Figure 1 The preliminary cleaning mechanism shown.

[0028] In use, the rotating drive mechanism drives the turntable 1 to rotate at a specific angle and then stops. The turntable 1 drives each cantilever 2 to move sequentially to the loading station, the preliminary cleaning station, the rewashing station, and the unloading station. At the loading station, the glass bottle is fixed to the cantilever 2 by the glass bottle positioning mechanism. At the preliminary cleaning station, the preliminary cleaning mechanism performs preliminary cleaning on the glass bottle. At the rewashing station, the rewashing mechanism performs rewashing on the glass bottle. At the unloading station, the cleaned glass bottle is removed.

[0029] It is well known that soaking before rinsing can more effectively remove impurities. Therefore, glass bottles are soaked before the initial rinsing. Figure 5 As shown, a cleaning fluid injection head 41 is installed above the loading station, and the cleaning fluid injection head 41 is connected to a second cleaning fluid supply mechanism. After the glass bottle is fixed to the glass bottle positioning mechanism with the bottle opening facing upwards, the second cleaning fluid supply mechanism can be used to deliver the cleaning fluid to the cleaning fluid injection head 41, which then injects the cleaning fluid into the glass bottle. Pre-filling the glass bottle with cleaning fluid allows for soaking, improving the effectiveness of subsequent cleaning. The second cleaning fluid supply mechanism can be the same as the first cleaning fluid supply mechanism. Specifically, the cleaning fluid injection head 41 is connected to a hose 312 via a pipe, and a control valve is installed on the pipe.

[0030] During soaking, the bottle opening should face upwards, but during initial cleaning and re-rinsing, the bottle opening should face downwards. Therefore, the cantilever 2 includes a connecting arm 21 and a rotating arm 22. The connecting arm 21 is fixed to the turntable 1, and one end of the rotating arm 22 extends into the connecting arm 21 and is rotatably mounted on the connecting arm 21. The rotating arm 22 is connected to an adjusting motor 23, and the bottle positioning mechanism is located at the end of the rotating arm 22 away from the connecting arm 21. When the turntable 1 moves the cantilever 2 to the initial cleaning station, the adjusting motor 23 drives the rotating arm 22 to rotate 180°, causing the glass bottle to rotate 180°, so that the bottle opening faces downwards.

[0031] After rinsing, a drying mechanism can be installed to promote rapid drying of the glass bottles. To reduce the number of devices, this invention integrates rinsing and drying into the same workstation, realizing a workflow of rinsing first and then drying. Specifically, as shown... Figure 5 , Figure 6 and Figure 7As shown, the rewashing station is equipped with a rewashing and drying mechanism, which includes a second lifting frame 51. The second lifting frame 51 is connected to a second lifting mechanism 52, which can be a cylinder. A spray pipe 53 is installed on the top of the second lifting frame 51, and the spray pipe 53 is connected to a clean water supply mechanism and an air supply mechanism. The second lifting frame 51, the second lifting mechanism 52, and other equipment can be installed below the water collection tank, so that the clean water after rewashing falls directly into the water collection tank.

[0032] During the second wash, the cantilever 2 moves the pre-washed glass bottle directly above the nozzle 53. The second lifting mechanism 52 moves the second lifting frame 51 upward, allowing the nozzle 53 to extend into the glass bottle. Then, the water supply mechanism supplies water to the nozzle 53, which sprays out to clean the inner wall of the glass bottle. After cleaning, the water supply mechanism stops supplying water, and the air supply mechanism supplies high-pressure air to the nozzle 53. The high-pressure air is sprayed onto the inner wall of the glass bottle, drying it. After drying, the air supply mechanism stops supplying air, and the second lifting mechanism 52 moves the second lifting frame 51 downward to its initial position, disengaging the nozzle 53 from the glass bottle.

[0033] To further improve the rewashing effect, the nozzle 53 is rotatably mounted on the second lifting frame 51. A rewashing motor 54 is connected to the lower end of the nozzle 53, which drives the nozzle 53 to rotate at high speed. A jacket 55 is provided on the second lifting frame 51. The jacket 55 is a circular sleeve with sealed ends and is fixedly mounted on the second lifting frame 51. The nozzle 53 passes through the jacket 55, and a through hole 56 is provided on the side wall of the nozzle 53 inside the jacket 55. The lower end of the nozzle 53 is sealed, and it has a central hole inside. The through hole 56 connects the central hole of the nozzle 53 to the inner cavity of the jacket 55.

[0034] The clean water supply mechanism includes a clean water pipe 57 connected in sequence. The clean water pipe 57 is a flexible pipe that can be bent and straightened. A second water pump 58 and a clean water tank 59 are also included. The clean water tank 59 stores clean water, and the second water pump 58 delivers the clean water from the clean water tank 59 to the clean water pipe 57. The air supply mechanism includes an air pipe 510 and an air compressor 511. The air pipe 510 is also a flexible pipe, and the air compressor 511 compresses air and delivers it to the air pipe 510. The air pipe 510 is connected to a jacket 55 via 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 is connected to the jacket 55 via a second valve 513. The air outlet direction of the first valve 512 is radially aligned with the jacket 55, and the water outlet direction of the second valve 513 is tangential to the jacket 55.

[0035] During the rewashing process, the water supply mechanism and the air supply mechanism operate simultaneously. Both the first valve 512 and the second valve 513 are open. Compressed air enters the jacket 55 through the first valve 512, and the air flow direction is consistent with the radial direction of the jacket 55. At the same time, pressurized water enters the jacket 55 through the second valve 513, and the water flow direction is perpendicular to the radial direction of the jacket 55, moving in a circular motion along the inner wall of the jacket 55. The air is impacted and sheared by the water flow, forming a large number of microbubbles. The water containing a large number of microbubbles then enters the nozzle 53 through the through hole 56.

[0036] like Figure 6 and Figure 7 As shown, a central column 514 coaxial with the nozzle 53 is provided inside the nozzle 53, and spiral guide vanes 515 are provided on the central column 514 and the inner wall of the nozzle 53. After entering the nozzle 53, the clean water moves upward in a spiral along the nozzle 53, which promotes further mixing of clean water and air and generates a large number of microbubbles.

[0037] The nozzle 53 has a vertical first outlet 516 at its top, and multiple second outlets 517 on its top sidewall. Each second outlet 517 is connected to a flexible water outlet pipe 518. Some clean water is sprayed out from the first outlet 516 to rinse the bottom of the glass bottle, while the remaining clean water enters the water outlet pipe 518 through the second outlets 517 and is then sprayed out from the water outlet pipe 518 to rinse the sidewalls of the glass bottle.

[0038] Because clean water contains a large number of tiny bubbles, the cavitation effect generated when these bubbles burst can effectively remove stubborn impurities, thoroughly wash away residual cleaning solution, and further improve the cleaning effect.

[0039] Furthermore, in traditional high-pressure cleaning nozzles, after spraying water onto the inner wall of the glass bottle, a large portion of the water collides with the glass bottle and flows rapidly downwards, resulting in high water consumption and dead zones during rinsing. In this invention, during the rewash, a rewash motor 54 drives the spray pipe 53 to rotate at 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. Under the action of centrifugal force, the water outlet pipe 518 will be in a horizontal state. Moreover, because the water outlet end of the water outlet pipe 518 is obstructed by the inner wall of the glass bottle, it bends and adheres to the inner wall. The water outlet direction of the water outlet pipe 518 is tangential to the inner wall of the glass bottle. Figure 8 As shown, after the water is sprayed out, it moves in a circular motion along the inner wall of the glass bottle, forming a swirling flow. This allows for a thorough and comprehensive cleaning of the inner wall of the glass bottle. Combined with the cavitation effect generated by the bursting of microbubbles, the cleaning effect is effectively improved.

[0040] After rewashing, the second valve 513 can be closed while the first valve 512 remains open, allowing high-pressure air to be introduced into the glass bottle to dry it.

[0041] In this invention, the glass bottle positioning mechanism can adopt various existing mechanisms that can stably clamp cylindrical parts, such as a three-jaw chuck 24, etc., and elastic rubber pads can be provided on the clamping surfaces of the jaws to prevent damage to the glass bottle.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
