[0041] Implementation Method 1

[0042] Reference Figures 1 to 5 This embodiment discloses an automatic packaging bottle washing machine, including a frame 1, on which a first driving mechanism and a rotating shaft are arranged, wherein the rotating shaft includes the upper column 6 and the lower column 7, and the bottom of the lower column 7 is rotatably mounted on the frame 1 through a rolling bearing;

[0043] The upper column 6 is rotatably connected to the lower column 7 via a rolling bearing. The first driving mechanism includes a driving motor 41 and a main transmission gear 42. The driving motor 41 is meshed with the main transmission gear 42 via a driving gear. The main transmission gear 42 is also connected to a bottle-push assembly 43 via a driven gear meshed therewith.

[0044] The main driving gear is connected to the lower column 7 via a connecting key, and the lower column 7 is rotatably connected to the frame 1 via a rolling bearing;

[0045] Since the upper column 6 is connected to the lower column 7 through a rolling bearing, and the lower column 7 is connected to the frame 1 through the rolling bearing and is also connected to the driving motor 41 through the main transmission gear 42, during the operation, the upper column 6 will remain stationary, while the lower column 7 will rotate under the drive of the driving motor 41; the advantage of adopting the above structure is that, among the components involved in the entire bottle washing machine, only the washing structure needs to move with the packaging bottles to be washed to remain relatively stationary, thereby extending the washing time, and the remaining power components and position adjustment components and other structures must remain stationary due to the line connection relationship and transmission needs. Therefore, the entire rotating shaft is divided into two sections, in which the upper column 6 acts as a stabilizing frame, thereby cooperating with the rotating lower column 7 to meet the requirements of different components, without the need to set up a complex stabilizing frame, which is conducive to simplifying the structure of the entire device;

[0046] At the same time, compared with structures such as a stabilizing frame, the power components and position adjustment components in the technical solution of the present application need to be arranged in a certain hierarchy in the vertical direction. If a stabilizing frame is used, multiple layers will inevitably be set up, which will further complicate the structure of the entire device and easily interfere with the components that rotate. The upper column 6 is not only simple in structure, but also coaxially arranged with the lower column 7, which can completely avoid the components that rotate, thereby simplifying the structure of the entire device and improving the stability and reliability of the device.

[0047] A lifting motor 8 and a lifting screw 9 connected by power are also provided at the bottom of the frame 1. A lifting seat 10 is threadedly connected to the lifting screw 9. A sliding rod 11 is also provided on the frame 1. The lifting seat 10 is slidably connected to the sliding rod 11. A limiting plate is also provided at the lower part of the sliding rod 11 to limit the position of the lifting seat 10 to avoid collision between the lifting seat 10 and the lifting motor 8, thereby improving the safety of the equipment. At the same time, the lifting seat 10 is limited by the sliding rod 11 to only move in the vertical direction;

[0048] The lifting seat 10 is also provided with a thrust ball bearing 12, and the bottom surface of the lower column 7 is also provided with a chuck 44, and the chuck 44 is in contact with the thrust ball bearing 12. The thrust ball bearing 12 can realize the rotation connection between the lower column 7 and the lifting seat 10, thereby ensuring that the basic function of the lower column 7 is not affected; on the other hand, it can also greatly improve the bearing capacity in the vertical direction, thereby improving the stability and reliability of the equipment;

[0049] A rolling bearing is also sleeved on the lifting seat 10, and the rolling bearing is in contact with the inner wall of the inner hole of the lower column 7. The rolling bearing can further improve the stability of the connection between the lifting seat 10 and the lower column 7, avoid the misalignment of the rotating shaft of the lower column 7 and the rotating shaft of the lifting screw 9, and improve the reliability and stability of the entire device;

[0050] The arrangement of the lifting structure can realize arbitrary adjustment of the height of the entire upper mechanism, thereby meeting the cleaning requirements of glass bottles of different heights and improving the adaptability of the equipment.

[0051] The frame 1 is also provided with a first lifting rail 4, which includes a connecting flange and a lifting frame connected to each other, and the lifting frame is fixed to the frame 1 through the connecting flange. At the same time, the lifting frame is an annular structure, and its axis coincides with the axis of the lower column 7;

[0052] Part of the top surface of the lifting frame is concave, and part of it is kept horizontal. The horizontal area and the concave area are smoothly connected by an inclined surface, so that an undulating end surface is formed on the top of the lifting frame, and the end surface is used as a lifting surface; wherein the position, height and width of the concave area are determined according to actual needs;

[0053] A first support plate 2 and a second support plate 3 are respectively arranged at the upper and lower ends of the lower column 7, and both the first support plate 2 and the second support plate 3 are circular plate-shaped structures. A plurality of mounting holes are arranged on the first support plate 2 and the second support plate 3, and the number of each mounting hole is determined according to the processing capacity, and 16, 24 or other parameters can be selected. After installation, the mounting holes on the first support plate 2 and the second support plate 3 correspond one to one, that is, the axes of the two corresponding mounting holes are coaxial;

[0054] A cleaning pipe 5 is provided in each mounting hole of the first support plate 2, and a lifting assembly is provided in each mounting hole of the second support plate 3;

[0055] The lifting assembly includes a base 25 and a bottle tray 26. The base 25 is connected to the second support plate 3 by bolts, and the axis of the base 25 is coaxial with the axis of the mounting hole. The bottle tray 26 is an inverted U-shaped structure, which is slidably sleeved on the base 25.

[0056] A lifting rod 27 is also slidably arranged in the base 25, and the top of the lifting rod 27 is connected to the bottle tray 26; a slide groove 45 is provided on the side of the base 25 facing the first lifting rail 4, and a connecting shaft is arranged on the side of the lifting rod 27, one end of the connecting shaft passes through the slide groove 45, and a roller 28 is also arranged at the end, and the roller 28 is in contact with the lifting surface of the top surface of the first lifting rail 4;

[0057] The first lifting rail 4 is also provided with an auxiliary lifting plate 29, which is located just above the concave area of ​​the lifting frame, and the shape of the auxiliary lifting plate 29 is the same as the shape of the concave area; the auxiliary lifting plate 29 can force the lifting assembly to be retracted, and when the lifting assembly cannot be retracted or is retracted slowly due to its own gravity, the lifting assembly is smoothly retracted, thereby ensuring that the packaging bottles to be cleaned are separated from the cleaning pipe 5 after cleaning, thereby improving the stability and reliability of the equipment operation, and the entire device has a simple structure and does not require additional control;

[0058] The cleaning tube 5 is a hollow tube, and a sliding sleeve 38 is also sleeved at the bottom thereof. A pressing plate 37 is also provided on the outer surface of the cleaning tube 5, and the pressing plate 37 is located directly above the sliding sleeve 38; a pressing spring 39 is also sleeved on the cleaning tube 5, and the two ends of the pressing spring 39 are respectively abutted against the pressing plate 37 and the sliding sleeve 38, and a sealing port 40 adapted to the bottle mouth structure of the packaging bottle to be cleaned is also provided at the bottom of the sliding sleeve 38, and the sealing port is connected with the cleaning tube 5;

[0059] The side wall of the cleaning pipe 5 is also provided with an overflow pipe 49, through which the water level in the cleaning pipe can be further accurately controlled to avoid excessive water addition;

[0060] When the packaging bottle to be cleaned gradually rises and is inserted into the sealing opening, the packaging bottle to be cleaned will further push the sliding sleeve 38 upward, thereby compressing the compression spring 39 until it moves to the highest point. At this time, the rebound force of the compression spring 39 will push the sliding sleeve 38 to clamp the packaging bottle to be cleaned, thereby sealing the bottle mouth to avoid leakage during the water filling process, thereby ensuring the stability and safety of the processing process;

[0061] At the same time, the above function can be realized by compressing the spring 39 and using the thrust of the bottle to be cleaned during its ascent. The structure is simple, which is not only conducive to simplifying the structure of the whole equipment, but also simplifies the control program by cleverly using the thrust of the cleaned glass bottle during its ascent, further improving the reliability and stability of the equipment.

[0062] A water adding assembly is also provided on the cleaning pipe 5, and the water adding assembly includes a water valve 30, and the water inlet end and the water outlet end of the water valve 30 are respectively connected to a water inlet pipe 32 and a water outlet pipe 33, and the water outlet pipe 33 penetrates the cleaning pipe 5 from the side wall thereof; a water delivery pipe 46 in an annular structure is also provided at the bottom of the first supporting plate 2, and the outer side of the water delivery pipe 46 is connected to the water inlet pipe 32;

[0063] A rotary joint 31 is inserted into the upper column 6, and the inner side of the water delivery pipe 46 passes through the lower column 7 and is connected to the rotary joint 31; the inlet end of the rotary joint 31 is connected to the external water source, so that the cleaning water is injected into each cleaning pipe 5 through the rotating structure;

[0064] An adjusting rod 34 is also provided on the frame 1, and an adjusting seat 35 is slidably provided on the adjusting rod 34. A mounting groove is provided on the side of the adjusting seat 35 facing the cleaning pipe 5, and an adjusting plate 36 is connected to the mounting groove through a connecting bolt; the adjusting plate 36 is an arc-shaped plate, and its central angle is determined according to the amount of water added, the speed of water addition and the rotation speed of the lower column 7, preferably 30°-45° and 44°; the inner side of the adjusting plate 36 protrudes outside the adjusting seat 35, and a guide surface is provided at its inlet end;

[0065] When the water valve 30 rotates with the cleaning pipe 5, the switch of the water valve 30 contacts the regulating plate 36, and the water valve 30 is opened under the pressure of the regulating plate 36, thereby realizing water filling; after the regulating plate 36 is rotated, the switch of the water valve 30 is disengaged from the regulating plate 36, and the water valve 30 is closed under the action of the reset device of the water valve 30, thereby realizing automatic water filling;

[0066] At the same time, the height of the adjustment plate 36 can be freely controlled by the adjustment rod 34 to meet the cleaning requirements of glass bottles of different heights;

[0067] Compared with the prior art, the structure of the adjustment plate 36 is very simple, which is not only conducive to reducing the cost of the whole set of equipment, but also very convenient to control and adjust, and the maintenance method is simple, which is conducive to improving the reliability and stability of the whole set of equipment;

[0068] Secondly, the above technical solution does not require the installation of additional solenoid valves or modification of the control program, which greatly simplifies the complexity of the equipment and the control of the equipment;

[0069] Finally, the regulating plate 36 described in the present application cleverly controls the water injection time by adjusting the contact time between the controller and the water valve 30 through the central angle. It has a simple structure and can achieve precise control of the amount of water added. While ensuring the cleaning quality, it avoids waste to the greatest extent, which is beneficial to reducing the cost of use. At the same time, the water addition time can be controlled by replacing different regulating plates 36. The method is simple and practical.

[0070] A brush assembly is also slidably arranged in the cleaning pipe 5, and the brush assembly includes a brush rotating shaft 16 and a cleaning brush 17 connected to each other; the brush assembly also includes a sliding frame 15 and a telescopic tube 47, wherein the telescopic tube 47 is inserted into the cleaning pipe 5 from the top thereof by sliding; a bearing seat is also arranged on the top of the sliding frame 15, and the telescopic tube 47 is connected to the sliding frame 15; the brush rotating shaft 16 is rotatably connected to the bearing seat;

[0071] A plurality of groups of connecting rods 24 are also provided on the top of the first support plate 2, each group having two connecting rods 24, each group of connecting rods 24 corresponds to each of the cleaning pipes 5, and is symmetrically arranged on both sides of the cleaning pipe 5, and the sliding frame 15 is provided with sliding holes adapted to the two connecting rods 24, and the sliding frame 15 is slidably connected to the connecting rods 24 by sliding;

[0072] The bottle washing machine further comprises a clutch drive assembly, which comprises a brush motor 13, a planetary gear 22 and a second lifting slide rail 14;

[0073] The second lifting rail 14 is a cylindrical structure, the inner side of which is connected to the upper column 6 through a truss structure; an adjustment groove 48 with a spiral structure is provided on its outer surface; a lifting roller 18 is also provided on the sliding frame 15, and the lifting roller 18 is inserted into the adjustment groove 48; the shape of the adjustment groove 48 needs to be determined according to the motion trajectory of the entire brush assembly;

[0074] The spiral structure forms a natural ups and downs structure; since the second lifting rail 14 is connected to the stationary upper column 6, the second lifting rail 14 does not move during operation; and the sliding plate rotates around the axis of the upper column 6 under the drive of the lower column 7, and then the driving sliding frame 15 of the adjustment slot 48 slides as required, thereby controlling the brush to enter and exit the packaging bottle to be cleaned;

[0075] Compared with the prior art, the present application can achieve arbitrary adjustment of the brush position by structural changes of the spiral adjustment groove 48. Compared with the traditional linear motor or adjustment cylinder, the adjustment method is simple and reliable. At the same time, it does not require the introduction of external equipment or the adjustment of the control program of the equipment.

[0076] The planetary gear 22 system includes a central gear 20, a support plate 21 and a plurality of planetary gears 22, wherein the support plate 21 is located directly above the first tray, and the support plate 21 is rotatably connected to the upper column 6 through a rolling bearing; at the same time, the support plate 21 is also connected to each of the connecting rods 24, so that the support plate 21 and the first support plate 2 are connected as a whole through the connecting rods 24, and the support plate 21 is driven to rotate through the first support plate 2;

[0077] The number of the planetary gears 22 is the same as the number of the cleaning tubes, and they correspond to the cleaning tubes one by one. A rotating seat 23 is also provided on the support plate, and the planetary gears 22 are connected to the rotating seat 23 respectively. The central gear 20 is rotatably connected to the upper column 6 through a rolling bearing, and the planetary gears 22 are meshed with the central gear 20 respectively.

[0078] A support plate is provided on the top of the upper column 6, and the brush motor 13 is installed on the support plate. The brush motor 13 is connected to the central gear 20 through a two-stage transmission gear power; thereby the central gear 20 is driven to rotate by the brush motor 13;

[0079] The top end of each brush rotating shaft 16 passes through the supporting plate 21, and a pressing plate 19 is also provided at the top end of the brush rotating shaft 16, and the pressing plate 19 is located directly above the planetary gear 22;

[0080] Due to the motion characteristics of the planetary gear 22 system, each planetary gear 22 can rotate around the central gear 20 while also being driven by the central gear 20 to rotate around its own rotation axis. The above motion characteristics can not only meet the overall rotation for transfer between various stations, but also meet the actual needs of transmitting power to each brush rotation axis 16, and the entire transmission device has a compact and stable structure.

[0081] The second lifting rail 14 can control the engagement state between the pressing plate 19 and the corresponding planetary gear 22 while controlling the brush to enter and exit the glass bottle, thereby arbitrarily controlling whether to connect the brush rotating shaft 16 and the power source as needed;

[0082] The above simple structures are combined to form a simple clutch device, which ensures that the brush rotates at high speed only after being inserted into the glass bottle, and enters and exits the glass bottle in a static or low-speed rotating state, ensuring the safety of the equipment. At the same time, it can also avoid splashing of cleaning water due to the uninterrupted high-speed rotation of the brush, ensuring the cleanliness of the entire equipment.

[0083] At the same time, the pressing disc 19 can also be slidably sleeved on the brush rotating shaft 16, and the brush rotating shaft 16 is provided with a limiting boss that abuts against the pressing disc 19; an adjusting nut 50 is also provided just above the pressing disc 19, and the adjusting nut 50 is threadedly connected to the brush rotating shaft 16, and an adjusting spring 51 is also sleeved on the brush rotating shaft 16, and the two ends of the adjusting spring 51 abut against the adjusting nut 50 and the pressing disc 19 respectively;

[0084] In the actual working process, the planetary gear is in a rotating state, while the pressing plate does not rotate. Therefore, if the pressing plate is fixedly connected to the brush rotating rod, the pressing plate and the planetary gear will have hard contact and finally engage with each other, which will cause serious wear on the pressing plate and the planetary gear.

[0085] With the above-mentioned structural arrangement, at the moment when the pressing disk contacts the planetary gear, the pressing disk will slide toward the side of the adjusting nut under the action of the planetary gear and compress the adjusting spring, and then reset through the adjusting spring, thereby ensuring that the pressing disk gradually engages with the planetary gear, greatly reducing the wear of the disk and the planetary gear, and extending the practical life of the equipment; at the same time, it can also prevent the pressing disk from being damaged during high-speed contact and engagement and the damaged parts from being thrown out and injuring people, thereby improving the safety of equipment operation.

[0086] When in use, the bottle washing machine described in this application works as follows:

[0087] First, the packaging bottles to be cleaned are transported to the bottle washing machine through the external glass bottle conveying mechanism;

[0088] After the bottle washing machine is started, its driving motor 41 drives the lower column and the bottle pushing mechanism to rotate, and the bottle pushing mechanism pushes the packaging bottles to be washed onto the bottle supporting plate 26; at this time, the entire lifting assembly is at the lowest point; at the same time, the sliding frame is at the highest working point, and the pressing plate and the planetary gear are disengaged from each other;

[0089] Due to the rotation of the lower column, the second support plate will drive the lifting assembly to rotate, and through the height change of the first lifting rail, the lifting rod is driven to extend and push the bottle tray 26 to rise;

[0090] After passing through the concave area of ​​the first lifting rail, the bottle to be cleaned is driven down by the bottle tray 26 and inserted into the sealing opening, and at the same time, the sliding sleeve is driven by the compression spring to compress the bottle opening of the bottle to be cleaned; at this time, the sealing process of the bottle to be cleaned is completed;

[0091] As the second support plate continues to rotate, the water valve will contact the adjustment plate, and finally the water valve will be opened by the pressure of the adjustment plate. During the continued rotation, the cleaning water will continue to be injected into the cleaning pipe and finally enter the packaging bottle to be cleaned;

[0092] When the water valve is out of contact with the adjustment plate, the water valve is reset and closed. At this time, due to the action of the second lifting slide rail, the sliding frame will slide downward, thereby gradually pushing the brush into the packaging bottle to be cleaned. When the brush is completely inserted into the packaging bottle to be cleaned, the pressing plate will fit with the top surface of the planetary gear, thereby driving the brush to rotate at a high speed to achieve cleaning of the glass bottle;

[0093] As the lower column continues to rotate, the brush will continue to rotate to clean the glass bottle. When the cycle enters the concave area of ​​the first lifting rail again, the second lifting rail will push the sliding frame to rise. At this time, the pressing plate will gradually disengage from the planetary gear, and the brush will gradually stop rotating. In the process of decelerating rotation, the peeled bottle will be withdrawn after cleaning.

[0094] Then, the cooperation between the auxiliary lifting plate and the first lifting rail forces the lifting rod to descend, driving the stripping bottle to gradually break away from the contact with the sliding sleeve, and completely withdraw after entering the concave area; at this time, another set of bottle-pushing devices is used to pull the stripping bottle out of the bottle washing machine after cleaning;

[0095] Repeating the above steps can achieve continuous cleaning of the glass bottles, greatly improving the cleaning efficiency;

[0096] Compared with the prior art, the present application divides the entire cleaning process into multiple stations through the first lifting slide rail, and continuously inputs the packaging bottles to be cleaned into each station of the bottle washing machine by rotation, thereby realizing continuous cleaning of glass bottles and greatly improving the cleaning efficiency; at the same time, the whole set of equipment realizes automatic control, reduces the requirements for manpower, not only helps to improve the cleaning efficiency, but also ensures the safety of cleaning;

[0097] Secondly, the position of the glass bottle in each station can be accurately controlled by the first lifting slide rail, which has a simple structure and does not require a complicated control program, greatly improving the stability and reliability of the control and reducing the cost of the entire device;

[0098] The present application is also provided with a clutch driving device, which controls the brush assembly to be inserted into or detached from the glass bottle through the clutch driving device, and ensures that the brush assembly is disconnected from the power assembly during the insertion or detachment process. After being inserted into the glass bottle, the brush assembly is connected to the power assembly so as to rotate at high speed, and then the inner surface of the glass bottle is cleaned during the high-speed rotation; the clutch driving device is used to achieve precise control of the brush position and movement state, thereby simplifying the control procedure; at the same time, compared with simple high-pressure flushing, the cleaning efficiency is higher, and the cleaning effect on stubborn dirt is better, which is beneficial to improving the cleaning quality.

[0099] Finally, compared with the prior art, in the technical solution described in the present application, except for the drive motor 41 and the brush motor which require electronic control, the lifting and lowering control of each component can be achieved through the first lifting slide rail and the second lifting slide rail with a specific structure, and the water valve is controlled by the adjustment plate, which are all mechanical structure controls and do not involve control procedures; and the drive motor 41 and the brush motor only have rotation as a movement mode, so their movement mode is relatively simple, that is, compared with the prior art, the present application simplifies the electric control system of the entire equipment to the maximum extent through the clever involvement of the mechanical structure, and simplifies the control program of the equipment; thereby improving the reliability and stability of the entire equipment.

Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
