Description

Technical Field

[0001] The present invention belongs to the field of filling equipment, and specifically relates to a sanitary dust-removing liquid filling machine. Background Art

[0002] Filling equipment is a common equipment used for filling and processing materials. When conducting operations such as the production of injection solutions, filling equipment is usually required for filling operations. The filling equipment is provided with a conveyor belt or a conveying component, which can convey containers filled with materials. Generally, a material pipe is provided at the top. As the material enters the container along the pipeline for filling operations, since the containers will be contaminated with dust during handling and subsequent placement on the conveyor belt, in order to make the surface of the filled containers cleaner and reduce dust adhesion, a blowing dust-removing component is usually provided on the filling equipment, and air at a certain speed is blown onto the surface of the filled containers to achieve the blowing dust-removing operation.

[0003] Chinese Patent No. CN220595398U discloses a filling equipment facilitating blowing dust removal, including a filling machine frame and a conveying frame. A blowing dust-removing component is provided on the conveying frame. The blowing dust-removing component includes a support frame. An air pump is fixedly installed on the top plate body of the support frame. The air outlet end of the air pump is fixedly installed with a conveying pipe. The end of the conveying pipe is fixedly installed with a horizontal pipe. An electrostatic eliminator is fixedly installed on the top of the conveying pipe. A plurality of nozzles are fixedly installed on the bottom of the horizontal pipe. A collecting component is provided at the bottom of the conveying frame. The collecting component includes a collecting cover. A fan is fixedly installed on the inner wall of the collecting cover. The bottom end of the collecting cover is fixedly installed with a dust outlet pipe. The end of the dust outlet pipe is fixedly installed with a threaded pipe. An outer sleeve is threadedly connected to the threaded pipe. A mesh cylinder is fixedly installed at the end of the outer sleeve. A filter screen is fixedly installed outside the mesh cylinder. By blowing gas through the provided blowing dust-removing component, as the gas blows onto the surface of the container for the blowing dust-removing operation, and in addition, through the provided electrostatic eliminator, the air is ionized into positive and negative ions by the electrostatic eliminator. After the air pump blows air, the positive and negative ions are blown onto the surface of the container to eliminate static electricity. After the static electricity is eliminated, it is beneficial for the blowing dust removal to be cleaner and more thorough, achieving a cleaner effect of blowing dust removal. And through the provided collecting component, the blown dust can be collected.

[0004] However, the above patent still has the following disadvantages:

[0005] 1. During the process of purging dust and filling, the container usually needs to move intermittently to leave time for the purging dust-removing mechanism and the filling mechanism to work. This working method cannot be carried out continuously, which will waste a lot of time and affect the efficiency of the overall filling work. Moreover, continuously starting and stopping the movement of the container will cause the liquid in the container to be easily spilled under the vibration generated by starting and stopping.

[0006] 2. The above patent cannot immediately carry out filling work after dust removal, so the container after dust removal is exposed to the air and is susceptible to secondary contamination before filling work, which affects the cleanliness of the container.

[0007] 3. Although the above patent is provided with a collection component to collect the blown dust and prevent the dust from falling into the container again, it essentially uses the fan to generate airflow to suck away the blown dust, and this method can only achieve good results under slower working conditions. If it is under high-speed continuous working conditions, the fan will not have time to suck away the dust, so it is not suitable for use under high-speed conditions. Summary of the invention

[0008] In order to overcome the deficiencies of the prior art, the present invention solves the technical problem of enabling the liquid injection connector and the gas injection connector to perform circular motion in a vertical state, and cooperating with the bottle body that is continuously transported in a straight line, so that the liquid injection pipe and the air blowing sleeve are continuously and stably extended into the bottle body for cleaning and filling, thereby realizing continuous and stable filling work, greatly improving the filling efficiency, and in one action process, successively and continuously realizing the air blowing cleaning and filling work, thereby improving the continuity between the processes, thereby improving the filling efficiency, and immediately performing the filling work after cleaning, effectively reducing the probability that the bottle body is again contaminated by dust after cleaning, by providing a baffle, which is unfolded during the cleaning and filling work, shielding the two sides of the bottle body from the airflow entrained with dust blown out from the bottle mouth of the bottle body, thereby avoiding secondary contamination of the adjacent bottle body, and after the cleaning and filling work is completed, the liquid injection pipe and the air blowing sleeve are separated from the bottle body, and the baffle is controlled to be closed, and the residual liquid dripping is received at the bottom of the liquid injection pipe by the liquid collecting groove, thereby avoiding the residual liquid dripping and making the bottle body or the filling device dirty.

Detailed implementation manners

[0035] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0036] As Figures 1-8 shown, a sanitary dust-removing liquid filling machine includes a cabinet body 10. Two sprockets 35 are rotatably connected to the cabinet body 10. A chain 36 is drivingly connected between the two sprockets 35. A plurality of groups of jaws 39 are fixedly connected to the outside of the chain 36. Each group of jaws 39 can hold and convey the bottle body 19 so that the bottle body 19 forms a straight line queue on one side of the chain 36. Second motors 42 are fixedly connected to the cabinet body 10 at positions corresponding to each sprocket 35. The power output end of each second motor 42 passes through the surface of the cabinet body 10 and is drivingly connected to the corresponding sprocket 35.

[0037] By arranging the chain 36 and the jaws 39, the bottle body 19 can be stably, quickly and continuously conveyed, so as to realize continuous filling work.

[0038] As Figures 1-8As shown in the figure, a feeding device and a discharging device are respectively arranged at both ends of the cabinet body 10. A group of guide plates 41 are fixedly connected to one end of the cabinet body 10 close to the feeding device. At the bottom edge of each gripper 39, staggered limiting pieces 40 extending outwards are arranged. At each link of the bottom of the chain 36, a guide wheel 37 is rotatably connected. A guide groove 38 consistent with the contour of the chain 36 is formed on the surface of the cabinet body 10, and each guide wheel 37 slides in the guide groove 38.

[0039] By setting the guide plates 41 and the limiting pieces 40, it can be ensured that the feeding device can send the bottles 19 into the corresponding grippers 39 one by one for clamping and conveying. And by setting the guide wheels 37 and the guide grooves 38, it can be ensured that the chain 36 always conveys the bottles 19 along a fixed track, preventing the chain 36 from shaking and causing the conveying position of the bottles 19 to shift, thus affecting the filling effect.

[0040] As Figures 1-8 shown in the figure, brackets 11 are fixedly connected to both sides of the surface of the cabinet body 10 where the bottles 19 are in a straight line queue. Rotating shaft sleeves 12 are respectively rotatably connected to the tops of the two brackets 11. The rotation centers of the two rotating shaft sleeves 12 are offset from each other. Swing arms 13 are respectively fixedly connected to the two ends of the two rotating shaft sleeves 12 close to each other. A liquid injection connector 14 and an air injection connector 15 are respectively rotatably connected to the two ends of the two swing arms 13. Each air injection connector 15 is fixedly arranged around the corresponding liquid injection connector 14. A liquid injection pipe 16 communicating with the inside of the liquid injection connector 14 is threadedly connected to the bottom of each liquid injection connector 14. A blowing sleeve 17 surrounding the outside of the liquid injection pipe 16 is threadedly connected to the bottom of each air injection connector 15. The liquid injection pipe 16 and the blowing sleeve 17 can extend into the inside of the bottle 19.

[0041] By setting the two rotating shaft sleeves 12 with offset centers, the liquid injection connector 14 and the air injection connector 15 can make circular motions in a state that is always vertical, so as to cooperate with the continuously linearly conveyed bottles 19, enabling the liquid injection pipe 16 and the blowing sleeve 17 to continuously and stably extend into the bottles 19 for cleaning and filling, thereby realizing continuous and stable filling work and greatly improving the filling efficiency.

[0042] Moreover, in one operation process, the blowing cleaning and filling work are successively and continuously realized, thereby improving the continuity between processes, further improving the filling efficiency, and immediately performing the filling work after cleaning, effectively reducing the problem of secondary pollution of the bottles 19 by dust after cleaning.

[0043] As Figures 1-8As shown, two ends of each rotating shaft sleeve 12 that are away from each other are respectively fixedly connected to a worm gear 28, and a group of rod seats 25 are fixedly connected at the corresponding position of the worm gear 28 on each bracket 11. A worm 26 that is rotatably connected to the corresponding worm gear 28 is meshed and transmission-connected in each group of rod seats 25. A first motor 27 is fixedly connected to one end of each group of rod seats 25, and each first motor 27 is transmission-connected to the corresponding end of the worm 26.

[0044] By providing the worm 26 and the first motor 27, the swing arm 13 can be driven to operate stably, thereby ensuring the stability of the operation of the filling device.

[0045] like Figures 1-8 As shown, the gas injection connector 15 is filled with an annular desiccant 18, the bottom opening position of the air blowing sleeve 17 is higher than the bottom opening position of the corresponding liquid injection tube 16, and a bearing 43 is provided at the rotational connection between each liquid injection connector 14 and the swing arm 13.

[0046] By providing the desiccant 18, it is possible to effectively retain moisture and dust in the air passing into the gas injection connector 15, thereby ensuring the cleanliness of the air ejected from the blowing sleeve 17 and further ensuring the cleaning effect. In addition, by providing the opening of the blowing sleeve 17 to be higher than the opening of the liquid injection tube 16 and leaving a certain space, the liquid in the bottle body 19 is not easy to contact the blowing sleeve 17 during the filling process, thereby ensuring the cleanliness of the blowing sleeve 17 and avoiding the contamination caused by the attached liquid being blown into the bottle body 19 when the remaining bottles 19 are subsequently cleaned.

[0047] A group of supports 22 are fixedly connected on both sides of the gas injection connector 15, and a group of relatively arranged baffles 20 are rotatably connected to the bottom end of each group of supports 22. The bottom ends of each group of baffles 20 can be closed with each other, and a liquid collecting tank 21 is arranged at the bottom end of each group of baffles 20. A servo 23 is fixedly connected to one side of each support 22, and a connecting rod 24 is fixedly connected to the power output end of each servo 23. Each connecting rod 24 is slidably connected to the top end of the corresponding support 22.

[0048] By setting up the baffle 20, it is unfolded during the cleaning and filling operations to shield the two sides of the bottle body 19 from the airflow entrained with dust blown out from the bottle mouth of the bottle body 19, thereby avoiding secondary contamination of the adjacent bottle body 19, and after the cleaning and filling operations are completed, the injection tube 16 and the blowing sleeve 17 are separated from the bottle body 19, and the baffle 20 is controlled to be closed, and the liquid collecting trough 21 is used to receive the dripping residual liquid at the bottom of the injection tube 16, thereby avoiding the residual liquid dripping and dirtying the bottle body 19 or the filling device.

[0049] like Figures 1-8As shown, a tee pipe 29 is fixedly connected inside each rotating shaft sleeve 12. At both ends of each tee pipe 29 close to the swing arm 13, an electrically controlled valve 30 is fixedly and communicatively connected respectively. At one end of each electrically controlled valve 30 away from the tee pipe 29, a connecting elbow 31 is fixedly and communicatively connected. At the top of each liquid injection connector 14, a set of rotating couplings 32 rotatably connected to the corresponding connecting elbow 31 are fixedly connected through the outer side of the end of the swing arm 13. A rotating seal ring 44 is arranged at the rotating connection between each set of rotating couplings 32 and the connecting elbow 31.

[0050] By providing the connecting elbow 31 and the tee pipe 29, the liquid and air can be stably supplied to the liquid injection connector 14 and the gas injection connector 15, and the supply routes of the liquid and air can be switched by controlling the electrically controlled valve 30, so as to ensure the normal progress of the filling work.

[0051] As Figures 1-8 shown, a set of first conductive slip rings 33 are arranged outside each rotating shaft sleeve 12. Each set of first conductive slip rings 33 is connected to the corresponding electrically controlled valve 30 through a wire. A set of second conductive slip rings 34 are arranged at the top of each liquid injection connector 14. Each second conductive slip ring 34 is connected to the corresponding steering gear 23 through a wire. Each second conductive slip ring 34 is connected to the corresponding first conductive slip ring 33 through a wire. A rotating sensor 45 is fixedly connected at the corresponding position of the rotating shaft sleeve 12 on the outside of the bracket 11.

[0052] By providing the first conductive slip ring 33 and the second conductive slip ring 34, the steering gear 23 and the electrically controlled valve 30 during rotation can be powered and controlled, and the wire winding can be avoided. By providing the rotating sensor 45, the rotation position of the swing arm 13 can be accurately judged, and then the positions of the liquid injection pipe 16 and the air blowing sleeve 17 can be accurately determined to facilitate controlling the electrically controlled valve 30 to switch the supply passages of the liquid and air.

[0053] In this embodiment, initially, the operator connects the device to the power supply and the control system. A feeding device is arranged at one end of the cabinet 10 where the guiding plate 41 is installed, and a discharging device is arranged at the other end to realize automatic feeding and discharging work. Then, the operator connects the liquid supply pipeline and the air supply pipeline to the two tee pipes 29 respectively.

[0054] During operation, starting the second motor 42 drives the chain 36 to circulate through the sprocket 35. Then, the grippers 39 move along with it. When each group of grippers 39 moves in an arc as it passes the sprocket 35, each group of grippers 39 opens. The feeding device continuously pushes the empty bottles 19 into the guide plate 41 and finally into the space between the opened grippers 39. As the grippers 39 continue to move with the chain 36, when the grippers 39 enter the linear movement state, each group of grippers 39 closes, firmly clamping and conveying the bottles 19, and simultaneously performing dust removal and filling operations during the conveying process. Subsequently, when the grippers 39 move the bottles 19 to another sprocket 35, the bottles 19 open again, and the discharging device removes the filled bottles 19 from the filling device for collection.

[0055] During the conveying and movement of the bottles 19, the first motor 27 is started synchronously to drive the two swing arms 13 to rotate at the same speed through the meshing transmission of the worm 26 and the worm gear 28. Then, it drives the two groups of liquid injection connectors 14 and gas injection connectors 15 to perform circular motion. Since the axes of the two rotating sleeves 12 are misaligned, a parallelogram motion mode is formed between the two swing arms 13 and the liquid injection connectors 14 and gas injection connectors 15. Thus, the liquid injection connectors 14 and gas injection connectors 15 always remain vertical while performing circular motion. At the same time, the linear movement speed of the bottles 19 is made consistent with the horizontal component speeds of the liquid injection connectors 14 and gas injection connectors 15. As a result, the two groups of liquid injection tubes 16 and the air blowing sleeves 17 alternately extend into the bottles 19. The rotation speeds of the rotating sleeves 12 and the swing arms 13 can be detected by the rotation sensor 45 and transmitted to the control system for precise control.

[0056] When the liquid injection tube 16 and the air blowing sleeve 17 extend into the bottle 19 and the rotation sensor 45 detects that the rotation angle of the rotating sleeve 12 reaches the specified angle, the electromagnetic control valve 30 located below the corresponding air supply pipeline is controlled to be connected and the electromagnetic control valve 30 located above is controlled to be closed. The two electromagnetic control valves 30 of the corresponding liquid supply pipeline both remain closed. Then, air enters the gas injection connector 15 through the corresponding swing arm 13, and after being dried and filtered by the desiccant 18, it is blown out from the annular gap between the air blowing sleeve 17 and the liquid injection tube 16 to purge the inside of the bottle 19. The clean air is blown into the bottle 19, and the air flow carries the dust out from the mouth of the bottle 19 to achieve the dust removal work.

[0057] When the air-blowing sleeve 17 and the liquid injection pipe 16 reach the limit position where they can no longer move downward, the rotation sensor 45 detects that the rotary shaft sleeve 12 has reached the specified rotation angle. At this time, the electric control valves 30 of all corresponding air supply pipelines are closed, and the electric control valve 30 located below the corresponding liquid supply pipeline is controlled to be connected and the electric control valve 30 located above is controlled to be closed. Then the liquid flows into the corresponding liquid injection connector 14 through the swing arm 13 and is finally injected into the bottle body 19 from the bottom end of the liquid injection pipe 16 for filling.

[0058] During the filling process, the liquid level in the bottle body 19 gradually rises. During the filling process, the liquid injection pipe 16 and the air-blowing sleeve 17 gradually lift upward and are gradually withdrawn from the bottle body 19. Since the bottom of the air-blowing sleeve 17 is higher than the liquid injection pipe 16, the air-blowing sleeve 17 will not directly contact the liquid surface, thereby ensuring the cleanliness of the air-blowing sleeve 17 and preventing liquid from adhering to the surface of the air-blowing sleeve 17, which may cause the adhered liquid to be blown into the bottle body 19 during the subsequent purging and dust removal process, resulting in contamination.

[0059] When the liquid injection pipe 16 and the air-blowing sleeve 17 are removed from the bottle body 19, the rotation sensor 45 still detects the rotation angle of the rotary shaft sleeve 12, and the control system closes the electric control valve 30. At this time, the dust removal and filling work of one bottle body 19 is just completed. As the swing arm 13 continues to rotate and the bottle body 19 continues to move, another group of liquid injection pipes 16 and air-blowing sleeves 17 gradually extend into the subsequent bottle body 19 for dust removal and filling work again, thus realizing continuous circulation. The bottle body 19 does not need to be continuously started and stopped intermittently to generate vibration, avoiding the problem of liquid spilling, so that the filling work is continuous, stable and efficient.

[0060] During the process of dust removal and filling work, when the air-blowing sleeve 17 extends into the bottle body 19, the control system controls the second electrical slip ring 34 to open the corresponding baffle 20, so that the baffle 20 blocks both sides of the bottle body 19, preventing the air flow from blowing towards the adjacent bottle bodies 19 on both sides during purging and dust removal, causing secondary pollution. When the liquid injection pipe 16 and the air-blowing sleeve 17 are withdrawn from the bottle body 19, at this time, the servo motor 23 is controlled to close the baffles 20. Even if the residual liquid in the liquid injection pipe 16 drips, it can be received by the liquid collecting groove 21, preventing the liquid from dripping and causing the surface of the bottle body 19 or the filling device to be soiled.

[0061] The above servo motor 23, the first motor 27, the electric control valve 30, the first electrical slip ring 33, the second electrical slip ring 34, and the second motor 42 are mature existing technologies. The structures in the drawings are only for illustration and will not be elaborated in this article.
