[0003] The existing filling machines have the following deficiencies: It is impossible to accurately receive the liquid remaining at the filling head during the bottle change process, and the synchronization is poor. When encountering a liquid with high viscosity, the residual part is very easy to stick to the filling head due to its high viscosity, and the dripping speed is slow, which is easy to cause the filling omission. At the same time, the liquid with high viscosity is attached to the surface of the filling head for a long time, which is easy to cause the filling head to be blocked and affect the filling effect; Stirring is generally used to prevent liquid stratification, but stirring often causes a large number of bubbles to be unable to be removed.

Detailed implementation mode

[0031] The principles and features of the present invention will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0032] The present invention provides the following preferred embodiments: Embodiment 1, as Figures 1-9 shown, an energy-saving filling machine includes a bottom plate 11, an installation plate 14 is fixed above the bottom plate 11, and further includes a feeding mechanism, a receiving mechanism and a filling mechanism; The filling mechanism includes a storage tank 12, a discharge pipe 19, a housing 16, a swivel cylinder 20, a feeding component, a transmission component and a driving component. The housing 16 is installed on one side of the installation plate 14. The storage tank 12 is rotatably arranged at the top of the installation plate 14. Specifically, a mounting bracket 15 is fixedly installed at the top of the installation plate 14. The storage tank 12 is rotatably arranged inside the mounting bracket 15 through a bearing. The mounting bracket 15 is used to support and guide the storage tank 12. The bottom end of the storage tank 12 is connected to the top end of the housing 16 to realize the connection between the storage tank 12 and the housing 16 and facilitate the flow of liquid materials. The discharge pipe 19 is fixed at the bottom end of the housing 16. Specifically, a filling head 50 is installed at the bottom end of the discharge pipe 19 to allow the liquid material to flow out for filling. The swivel cylinder 20 is rotatably arranged inside the housing 16. Specifically, a cavity is provided inside the housing 16. The outer diameter of the swivel cylinder 20 matches the inner diameter of the cavity, and the swivel cylinder 20 is rotatably arranged inside the cavity. The driving component is located between the swivel cylinder 20 and the installation plate 14, and the driving component is used to realize the rotation of the swivel cylinder 20. The feeding component is located on one side of the housing 16. The driving component can adjust the flow direction of the material, and the feeding component can realize quantitative storage and feeding of the material, and then can realize the effect of quantitative filling to meet the use requirements. The transmission component is located between the feeding component and the storage tank 12; When the feeding component operates, it can drive the storage tank 12 to rotate reciprocally inside the mounting frame 15 through the transmission component. When the storage tank 12 rotates, the liquid material inside the storage tank 12 can surge to achieve the effect of mixing, avoiding material stratification. At the same time, it can effectively prevent the problem of a large number of bubbles caused by stirring in the prior art, eliminating the need for additional installation of a stirring mechanism and a defoaming mechanism, thus saving costs; The feeding mechanism includes a conveyor 51 and a rotating component. The conveyor 51 is installed above the bottom plate 11, and the rotating component is located between the conveyor 51 and the mounting plate 14. The rotating component enables the conveyor 51 to only drive a certain distance each time, so that the bottles above the conveyor 51 can be sequentially moved below the discharge pipe 19, which is conducive to realizing continuous filling; The receiving mechanism includes a receiving tray 43, a reciprocating sliding component, and a scraping component. The receiving tray 43 is arranged below the discharge pipe 19, and the reciprocating sliding component is located between the receiving tray 43 and the rotating component. At the same time, during the process of bottle movement for bottle replacement, the receiving tray 43 can move below the discharge pipe 19 under the action of the reciprocating sliding component to receive the residual liquid at the filling head 50, preventing the residual material from dripping directly downward. That is, it can accurately receive the residual liquid at the filling head 50 during the bottle replacement process with high synchronism. The scraping component is installed inside the receiving tray 43. When the receiving tray 43 moves below the filling head 50 to receive the dripping material, the scraping component inside the receiving tray 43 can scrape the bottom end surface of the filling head 50 to avoid the situation where the residual material at the bottom end of the filling head 50 has a slow dripping speed due to high viscosity, resulting in missed reception. It should be noted here that generally, the residual liquid at the filling head 50 is less, and its amount is within the filling error range.

[0033] As Figures 1-9 shown, the feeding component includes a filling pipe 26, a piston plate 27, a push rod 28, an electric push rod 30, and a first connecting rod 31. One side of the housing 16 is connected with an intermediate pipe 18, and the other end of the intermediate pipe 18 is connected with the filling pipe 26. The filling pipe 26 is fixedly installed on one side of the mounting plate 14; The piston plate 27 is slidably arranged inside the filling pipe 26. Specifically, the piston plate 27 is in sealed sliding connection with the filling pipe 26. The push rod 28 is inserted into the end of the filling pipe 26 away from the housing 16, and one end of the push rod 28 is fixedly connected with the piston plate 27. The electric push rod 30 is fixedly installed on one side of the mounting plate 14, and the output end of the electric push rod 30 is connected with one end of the first connecting rod 31. The other end of the first connecting rod 31 is connected with the end of the push rod 28 away from the piston plate 27. It should be noted here that in order to ensure the pressure balance inside the filling pipe 26, a through hole 29 should be opened on the surface of the end of the filling pipe 26 away from the housing 16 to ensure that the internal air pressure of the filling pipe 26 can remain balanced when the piston plate 27 is pushed and pulled; During use, when the feed pipe 17 is connected to the intermediate pipe 18 through the swivel cylinder 20, the electric push rod 30 is controlled to work, driving the first connecting rod 31 to move away from the housing 16. At this time, the first connecting rod 31 drives the push rod 28 to move, causing the piston plate 27 to move away from the housing 16 inside the filling pipe 26. Under the action of negative pressure, the liquid inside the storage tank 12 is sucked into the filling pipe 26 for storage; Subsequently, after sucking a certain amount of liquid, the drive assembly drives the swivel cylinder 20 to rotate, enabling the intermediate pipe 18 to be connected to the discharge pipe 19 through the swivel cylinder 20. At this time, the electric push rod 30 is controlled to work, and the piston plate 27 moves in the reverse direction, pushing the liquid stored inside the filling pipe 26 out from the discharge pipe 19 to achieve blanking and filling.

[0034] As Figures 1-9 shown, a feed pipe 17 is installed at the top of the housing 16, and a blanking pipe 52 is fixed to the bottom of the storage tank 12. The bottom end of the blanking pipe 52 is inserted into the feed pipe 17, and the blanking pipe 52 and the feed pipe 17 are rotatably connected through a bearing. Specifically, to ensure the sealing effect, a sealed bearing should be selected for the bearing between the blanking pipe 52 and the feed pipe 17, which will not affect the rotation of the blanking pipe 52 inside the feed pipe 17. Two openings 21 are provided on the surface of the swivel cylinder 20. The inner diameters of the feed pipe 17, the intermediate pipe 18, the discharge pipe 19, and the two openings 21 are all the same, facilitating the docking of the opening 21 with the feed pipe 17 or the intermediate pipe 18 or the discharge pipe 19; In the initial state, the two openings 21 are respectively connected to the feed pipe 17 and the intermediate pipe 18, that is, the liquid inside the storage tank 12 can flow from the feed pipe 17 to the intermediate pipe 18 when pulled by the piston plate 27 and be stored inside the filling pipe 26 to prepare for the next filling; Subsequently, the drive assembly drives the swivel cylinder 20 to rotate, enabling the two openings 21 to be respectively connected to the intermediate pipe 18 and the discharge pipe 19, that is, the liquid stored inside the filling pipe 26 can move from the intermediate pipe 18 to the discharge pipe 19 when pushed by the piston plate 27, enabling the liquid to flow out from the filling head 50 into the bottle to achieve filling.

[0035] As Figures 1-9 shown, the drive assembly includes a first motor 22, a driving wheel 23, a driven wheel 24, and a transmission belt 25. Shafts are fixed to both ends of the swivel cylinder 20, and the shafts are rotatably arranged on the housing 16 through bearings. One of the shafts passes through the housing 16 and the mounting plate 14 and is fixedly connected to the driven wheel 24. The driving wheel 23 is rotatably arranged on one side of the mounting plate 14. The transmission belt 25 is sleeved on the driving wheel 23 and the driven wheel 24. The diameter of the driven wheel 24 is larger than that of the driving wheel 23, which can achieve a deceleration effect. The first motor 22 is fixedly installed on the mounting plate 14, and the output end of the first motor 22 is fixedly connected to the driving wheel 23; During use, when it is necessary to adjust the direction of the liquid, the first motor 22 is controlled to work, and the first motor 22 drives the driving wheel 23 to rotate, and under the action of the transmission belt 25, it can drive the driven wheel 24 to rotate, so that the steering cylinder 20 can rotate inside the cover 16, driving the two openings 21 to rotate, thereby realizing the adjustment of the liquid flow direction.

[0036] like Figures 1-9 As shown, the transmission assembly includes a ring gear 32, a rack 33, a guide rail 34 and a second connecting rod 35. The ring gear 32 is fixedly sleeved on the surface of the storage tank 12. The guide rail 34 is located on one side of the ring gear 32 and is fixedly mounted on the mounting plate 14. The rack 33 is slidably arranged inside the guide rail 34. The guide rail 34 is used to guide the rack 33 to increase the stability of the rack 33 during movement. The rack 33 and the ring gear 32 are meshed with each other. One end of the second connecting rod 35 is connected to the rack 33, and the other end of the second connecting rod 35 is connected to the end of the push rod 28 away from the piston plate 27. When the push rod 28 moves in a direction away from the housing 16, the push rod 28 drives the rack 33 to move in the same direction inside the guide rail 34 through the second connecting rod 35. Since the rack 33 and the ring gear 32 are meshed, the ring gear 32 can rotate when the rack 33 moves, so that the storage tank 12 can rotate inside the mounting frame 15. Similarly, when the push rod 28 moves in the reverse direction, the rack 33 can drive the gear ring 32 to rotate in the reverse direction, so that the storage tank 12 can rotate in the reverse direction; When the storage tank 12 rotates, the liquid material inside the storage tank 12 can surge to achieve a mixing effect, thereby avoiding material stratification. At the same time, since the diameter of the gear ring 32 is large, the rotation angle of the storage tank 12 is small and it will not rotate significantly. It can also effectively prevent the problem of a large number of bubbles caused by stirring in the prior art.

[0037] like Figures 1-9 As shown, the rotating assembly includes a groove wheel 36, a driving disk 37, an insertion rod 38 and a second motor 49. The groove wheel 36 is located at one side of the conveyor 51 and is fixedly connected to one of the driving shafts of the conveyor 51, that is, when the groove wheel 36 rotates, it can drive one of the driving shafts of the conveyor 51 to rotate, thereby realizing the transmission of the conveyor 51 and further realizing the movement of the bottle. The driving disk 37 is rotatably set on the mounting plate 14, and the insertion rod 38 is fixed to one side of the driving disk 37; The surface of the groove wheel 36 is annularly and equidistantly provided with four concave locking arcs that match the outer edge of the driving disk 37, and a radial groove is provided between two adjacent concave locking arcs. The second motor 49 is fixedly mounted on one side of the mounting plate 14, and the output end of the second motor 49 is connected to the driving disk 37, that is, the second motor 49 can drive the driving disk 37 to rotate when working; In the initial state, if Figure 9As shown, during operation, the second motor 49 drives the drive disk 37 to rotate clockwise. Since the concave locking arc of the grooved pulley 36 is caught by the outer edge of the drive disk 37, the grooved pulley 36 will not rotate along with the rotation of the drive disk 37. As the drive disk 37 continues to rotate, the drive disk 37 drives the plug rod 38 to rotate synchronously. When the plug rod 38 just enters the radial groove inside the grooved pulley 36, at this time the locking arc is just released. After that, the grooved pulley 36 is driven by the plug rod 38 to rotate. During this process, the conveyor 51 can drive the bottle to move, achieving the effect of bottle replacement, so that the next bottle just moves below the filling head 50 and waits for filling. When the plug rod 38 leaves the radial groove on the other side, the locking arc is caught again, and the grooved pulley 36 stops moving until the plug rod 38 enters another radial groove of the grooved pulley 36 again, and the above-mentioned movement is repeated; It should be noted that during the period when the concave locking arc of the grooved pulley 36 is caught by the outer edge of the drive disk 37, that is, when the conveyor 51 is not driving, the bottles on the conveyor 51 are stationary. During this period, the filling mechanism needs to complete one suction process (the process of liquid being sucked from the storage tank 12 into the filling pipe 26), turning process (rotating the turning cylinder 20 so that the intermediate pipe 18 and the discharge pipe 19 can be connected), and pushing process (pushing the liquid inside the filling pipe 26 out through the intermediate pipe 18 and the discharge pipe 19), that is, completing one filling operation; When the grooved pulley 36 is driven by the plug rod 38 to rotate, that is, when the conveyor 51 is driving and the bottles on the conveyor 51 move to achieve bottle replacement, the filling mechanism needs to complete one turning process so that the turning cylinder 20 can rotate to a state where the feed pipe 17 and the intermediate pipe 18 are connected to facilitate subsequent suction work.

[0038] As Figures 1-9 shown, the reciprocating sliding assembly includes a cam 39, a ball 41, a moving rod 42, a limiting plate 44 and a spring 45. The cam 39 is fixed on one side of the drive disk 37, that is, when the drive disk 37 rotates, it can drive the cam 39 to rotate. A sliding seat 48 is fixed on one side of the mounting plate 14. The moving rod 42 is slidably arranged inside the sliding seat 48. The ball 41 is arranged at one end of the moving rod 42. The ball 41 and the moving rod 42 cooperate with each other. The ball 41 can roll at the end of the moving rod 42, and the ball 41 abuts against the side wall of the cam 39. The other end of the moving rod 42 is connected to the receiving tray 43; The limiting plate 44 is fixedly installed on the side of the moving rod 42 close to the receiving tray 43. The spring 45 is sleeved on the surface of the moving rod 42, and the two ends of the spring 45 are respectively connected to the sliding seat 48 and the limiting plate 44; In the initial state, the receiving tray 43 is located at the lower left of the filling head 50, and the spring is in a stretched state. When the cam 39 rotates with the driving disk 37, the spring 45 can drive the moving rod 42 to move toward the cam 39, so that the receiving tray 43 can be away from the filling head 50, providing an avoidance effect for filling; When changing bottles after one filling is completed, as the drive disk 37 rotates, the cam 39 rotates from the vertical state to the horizontal state again. At this time, the receiving tray 43 is moved to the bottom of the filling head 50 again to receive the remaining liquid.

[0039] like Figures 1-9 As shown, the scraping assembly includes a scraper 46 and an inclined material guide plate 47. The scraper 46 is L-shaped and fixedly installed inside the receiving tray 43. The top end surface of the scraper 46 is flush with the bottom end surface of the filling head 50. The inclined material guide plate 47 is fixedly arranged on one side of the scraper 46. When the receiving tray 43 moves to below the filling head 50, the receiving tray 43 drives the scraper 46 to move, so that the scraper 46 can scrape the surface of the filling head 50 to prevent the residual material at the bottom of the filling head 50 from dripping slowly due to its high viscosity, resulting in missed materials. At the same time, the inclined material guide plate 47 can guide the scraped material.

[0040] like Figures 1-9 As shown, a guide groove 40 for guiding and limiting is formed on the outer edge of the cam 39, and a ball 41 is located inside the guide groove 40 to ensure that the moving rod 42 can move telescopically more stably.

[0041] like Figures 1-9 As shown, the inner wall of the storage tank 12 is provided with a toggle bar 13, which is spiral-shaped and can guide the material, thereby improving the mixing effect of the material.

[0042] The specific working process of the present invention is as follows: First, the second motor 49 drives the driving disk 37 to rotate clockwise. Since the inner concave locking arc of the groove wheel 36 is stuck by the outer edge of the driving disk 37, the groove wheel 36 will not rotate with the rotation of the driving disk 37. When the cam 39 rotates with the driving disk 37, the spring 45 can drive the moving rod 42 to move toward the cam 39, so that the receiving tray 43 can be away from the filling head 50, providing an avoidance effect for filling; During this period (i.e., the period when the conveyor 51 does not drive the bottle to move), the electric push rod 30 is controlled to work to drive the first connecting rod 31 to move towards the side away from the housing 16. At this time, the first connecting rod 31 drives the push rod 28 to move, so that the piston plate 27 moves inside the filling pipe 26 in the direction away from the housing 16. Under the action of negative pressure, the liquid inside the storage tank 12 is sucked into the filling pipe 26 for storage. Subsequently, the first motor 22 is controlled to work, and the first motor 22 drives the driving wheel 23 to rotate. Under the action of the transmission belt 25, the driven wheel 24 can be driven to rotate, so that the steering cylinder 20 can rotate inside the housing 16, driving the two openings 21 to rotate, realizing the adjustment of the liquid flow direction, so that the two openings 21 can communicate with the intermediate pipe 18 and the discharge pipe 19 respectively. At this time, the electric push rod 30 is controlled to work, and the piston plate 27 moves in the reverse direction, pushing out the liquid stored inside the filling pipe 26 from the discharge pipe 19, realizing blanking and filling; That is, during the period when the inner concave locking arc of the sprocket 36 is caught by the outer edge of the driving disc 37 and the conveyor 51 is not driving, the bottles on the conveyor 51 are stationary. During this period, the filling mechanism completes one suction process (the process of sucking the liquid from the storage tank 12 into the filling pipe 26), steering (the process of rotating the steering cylinder 20 so that the intermediate pipe 18 and the discharge pipe 19 can communicate), and pushing process (the process of pushing the liquid inside the filling pipe 26 through the intermediate pipe 18 and the discharge pipe 19), that is, completing one filling operation; As the driving disc 37 continues to rotate, the driving disc 37 drives the plug rod 38 to rotate synchronously. When the plug rod 38 just enters the radial groove inside the sprocket 36, at this time the locking arc is also just released. After that, the sprocket 36 is driven by the plug rod 38 to rotate. During this process, the conveyor 51 can drive the bottle to move, realizing the effect of bottle replacement, so that the next bottle just moves below the filling head 50 and waits for filling. When the plug rod 38 leaves the radial groove on the other side, the locking arc is caught again, and the sprocket 36 stops moving until the plug rod 38 enters another radial groove of the sprocket 36 again, repeating the above movement; When the sprocket 36 is driven by the plug rod 38 to rotate, that is, when the conveyor 51 is driving and the bottles on the conveyor 51 are moving to realize bottle replacement, the filling mechanism needs to complete one steering so that the steering cylinder 20 can rotate to the state where the feed pipe 17 and the intermediate pipe 18 communicate with each other for subsequent suction work; During the process of bottle replacement, as the drive disk 37 rotates, the cam 39 rotates from the vertical state to the horizontal state again. At this time, the receiving tray 43 is moved below the filling head 50 again to receive the remaining liquid. When the receiving tray 43 is moved below the filling head 50, the receiving tray 43 drives the scraper 46 to move, so that the scraper 46 can scrape the surface of the filling head 50, avoiding the situation that the residual material at the bottom of the filling head 50 has a slow dripping speed due to its high viscosity, resulting in missed reception. At the same time, the inclined guide plate 47 can play a role in guiding the material and guiding the scraped material. By repeating the above steps, continuous filling can be achieved.

[0043] When the push rod 28 moves away from the housing 16, the push rod 28 drives the rack 33 to move in the same direction inside the guide rail 34 through the second connecting rod 35. Since the rack 33 meshes with the gear ring 32, when the rack 33 moves, the rotation of the gear ring 32 can be realized, so that the storage tank 12 can rotate inside the mounting frame 15; similarly, when the push rod 28 moves in the reverse direction, the rack 33 can drive the gear ring 32 to rotate in the reverse direction, so that the storage tank 12 can rotate in the reverse direction; when the storage tank 12 rotates, the liquid material inside the storage tank 12 can surge to achieve the effect of mixing, avoiding material stratification, and at the same time effectively preventing the problem of a large number of bubbles caused by stirring in the prior art.

[0044] The beneficial effects of the present invention are specifically embodied in the above. The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
