Description

Technical Field

[0001] This utility model relates to the field of filling machine technology, specifically a multi-station rotary filling machine. Background Technology

[0002] Multi-station rotary filling machines are devices that use a rotating worktable to drive containers through multiple functional stations in sequence to achieve continuous automated filling and auxiliary processes. They are widely used in the large-scale production of liquids, pastes and other materials, and can efficiently complete integrated operations such as filling, sealing and labeling.

[0003] Existing multi-station rotary filling machines use a rotary worktable as their core, driven by a motor and reducer to perform circular motion. Multiple workstations are evenly distributed on the table for placing containers. Together with the filling mechanism (such as plunger type, gear pump type, etc., selected according to the material characteristics), quantitative filling is completed. The working principle follows the logic of "continuous flow and division of labor": after the empty container enters the feeding workstation via the conveyor belt, the positioning device fixes it on the workstation of the rotary worktable; the rotation of the worktable drives the containers to move in sequence. When they arrive at the filling workstation first, the filling mechanism accurately injects the material according to preset parameters (such as time and pressure), realizing high-speed and precise automated production.

[0004] During use, some liquids and pastes tend to adhere to the end of the injection tube in existing rotary filling machines. These liquids and pastes can easily drip and cause contamination, while some pastes can solidify and clog the injection tube, thus affecting the stability and safety of the filling process. Utility Model Content

[0005] The technical problem to be solved by this utility model is that in the process of using existing rotary filling machines, some liquids and pastes are easily adsorbed at the end of the injection tube, and the liquids and pastes are easy to drip and contaminate. At the same time, some pastes are easy to solidify and block the injection tube, thus affecting the filling stability and safety.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A multi-station rotary filling machine includes a frame, two rotating tables rotatably connected to the top of the frame, a tank fixed in the middle of the frame, several positioning slots on the surface of each rotating table, electric push rods fixed on the two side walls of the frame near the positioning slots, injection tubes fixed at the output ends of the electric push rods, metering pumps installed on the side walls of the tank near the electric push rods, connecting pipes inserted into the other ends of the metering pumps, mounting brackets fixed on the side walls of the frame near the injection tubes, limiting cylinders fixed at the top of the mounting brackets, inner liner snapped into the middle of the limiting cylinders, a sliding groove for the mounting brackets to slide in the middle of the inner liners, a through groove at the bottom end of the mounting brackets near the limiting cylinders, a receiving hopper rotatably connected to the middle of the limiting cylinders, and a second motor fixed at the top of the mounting brackets.

[0007] The beneficial effects of this utility model are: when the injection tube is filled and there is residue at the bottom, the injection tube can be moved vertically upward by the reverse drive electric push rod. The inner liner and the injection tube work together to scrape off the residue at the bottom of the injection tube. Then, the second motor is started to drive the receiving hopper to rotate to the bottom of the limiting cylinder to receive the scraped residue. This avoids contamination of the rotating table surface and blockage at the bottom of the injection tube, thus improving the stability of subsequent injections.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the other ends of the two connecting tubes are respectively inserted into the side wall of the top of the injection tube, and the connecting tubes are respectively connected to the injection tube, with the injection tube located directly above the positioning groove.

[0010] Furthermore, a locking block is fixed on the side wall of the inner liner, and a locking groove is opened on the inner side wall of the limiting cylinder, with the locking block engaging in the middle of the locking groove.

[0011] Furthermore, the chute is funnel-shaped and passes through the balance valve, with the balance valve and the chute located in the same vertical direction.

[0012] Furthermore, the output end of the second motor is fixedly mounted on the end of the receiving hopper, and a receiving box is snapped into the middle of the receiving hopper.

[0013] Furthermore, two first motors are fixed at the bottom of the frame, and reducers are installed at the output ends of the first motors respectively. The other ends of the reducers are fixed to the bottom of the rotary table through couplings.

[0014] Furthermore, each of the tops of the frame is connected to a feed pipe, which is connected to the inside of the tank.

[0015] Furthermore, a balance valve is installed at the top of the frame near the feed pipe, and a filter element is snapped into the middle of the balance valve.

[0016] The beneficial effects of adopting the above-mentioned further solution are as follows: by cooperating with the card block and the card slot, the card block is engaged in the middle of the card slot, which improves the stability and convenience of the inner liner installation and facilitates the disassembly and replacement of the inner liner; the receiving box is engaged in the middle of the receiving hopper, and when the receiving box is full, starting the second motor can drive the receiving box to rotate synchronously with the receiving hopper, thereby cleaning and maintaining the receiving box.

In the description of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0026] like Figure 1-5As shown, the multi-station rotary filling machine includes a frame 1. Two rotary tables 2 are rotatably connected to the top of the frame 1. A tank 3 is fixed in the middle of the frame 1, used to temporarily store liquids or pastes to be filled. Several positioning slots 12 are formed on the surface of each rotary table 2. These slots 12 are used to engage containers, which are various shapes and materials, such as bottles, cans, and barrels, used to hold materials. Electric actuators 4 are bolted to the two side walls of the frame 1 near the positioning slots 12. An injection tube 8 is fixed to the output end of each electric actuator 4 via a coupling. The injection tube 8 is located directly above the positioning slots 12 for positioning and injection. Activating the electric actuator 4 drives the injection tube. 8. The pump moves vertically into the container to improve injection accuracy. Metering pumps 6 are installed on the side walls of the tank 3 near the electric push rod 4. One end of each metering pump 6 is connected to the bottom of the tank 3. The metering pump 6 is a positive displacement pump that can precisely control the fluid delivery volume. It is mainly used to quantitatively deliver liquid according to a set flow rate or volume. The metering pump 6 drives the plunger, diaphragm, and other components inside the pump to reciprocate through a drive mechanism such as a motor, changing the pump chamber volume to achieve liquid suction and discharge. The flow rate is precisely controlled by adjusting the stroke length or frequency. The metering pump 6 is existing technology and will not be described in detail here. The other end of each metering pump 6 is connected to a connecting pipe 7. The other ends of the two connecting pipes 7 are respectively connected to the injection... On the side wall of the top of the tube 8, the injection tube 8 is made of stainless steel and is used for insertion. The connecting tube 7 is connected to the injection tube 8. When the metering pump 6 is started, the material inside the tank 3 can be transported to the container through the connecting tube 7 and the injection tube 8 to achieve filling. Mounting brackets 9 are fixed to the side wall of the frame 1 near the injection tube 8 by bolts. The top of the mounting bracket 9 is fixed with a limiting cylinder 10 by welding. The inner liner 14 is snapped into the middle of the limiting cylinder 10. The inner liner 14 is made of silicone. A sliding groove 18 is opened in the middle of the inner liner 14 for the mounting bracket 9 to slide. A through groove 17 is opened at the bottom of the mounting bracket 9 near the limiting cylinder 10. The sliding groove 18 is funnel-shaped and passes through the balance valve 13. 3 and the through groove 17 are located in the same vertical direction. The middle of the limiting cylinder 10 is rotatably connected to the receiving hopper 15. The top of the mounting frame 9 is fixed with a second motor 16. The output end of the second motor 16 is fixed to the end of the receiving hopper 15. When the injection tube 8 is filled and there is residue at the bottom, the electric push rod 4 can drive the injection tube 8 to move vertically upward. The inner liner 14 and the injection tube 8 work together to scrape off the attached material at the bottom of the injection tube 8. Then the second motor 16 is started to drive the receiving hopper 15 to rotate to the bottom of the limiting cylinder 10 to receive the scraped residue, thereby avoiding contamination of the surface of the rotating table 2 and preventing the bottom of the injection tube 8 from being blocked, thus improving the stability and safety of the filling.

[0027] like Figures 3-5As shown, a locking block 19 is fixed on the side wall of the inner liner 14, and a locking groove 20 is opened on the inner side wall of the limiting cylinder 10. The inner liner 14 and the locking block 19 are fixedly connected by silicone material to form an integral structure. The locking block 19 is locked in the middle of the locking groove 20, which improves the stability and convenience of the installation of the inner liner 14, thereby facilitating the disassembly and replacement of the inner liner 14.

[0028] As shown in the figure Figures 3-5 As shown, a receiving box 21 is attached to the middle of the receiving hopper 15. The receiving box 21 is made of plastic and is used to receive scraped impurities. When the receiving hopper 15 rotates out of the interior of the mounting frame 9, the operator can take out the receiving box 21 for cleaning, thereby improving the convenience of maintenance.

[0029] As shown in the figure Figures 1-2 As shown, two first motors 11 are fixed at the bottom of the frame 1. The output ends of the first motors 11 are respectively equipped with reducers. The other ends of the reducers are fixed to the bottom of the rotary table 2 through couplings. The top of the frame 1 is connected to the feed pipe 5, which is connected to the inside of the tank 3. The top of the frame 1 near the feed pipe 5 is equipped with a balance valve 13 to balance the air pressure. The middle of the balance valve 13 is fitted with a filter element to filter the air and prevent the inside of the tank 3 from being contaminated, thereby improving the stability of the filling of the tank 3.

[0030] Working Principle: When using this multi-station rotary filling machine, the operator first connects the external power supply, then sequentially clamps the containers to be filled into the positioning slots 12. Containers are vessels used to hold materials and can take the form of bottles, cans, barrels, etc. Container technology is existing and will not be described in detail here. Next, the first motor 11 is started, driving the rotary table 2 to rotate, causing the positioning slots 12 to rotate sequentially to directly below the injection tube 8. When the positioning slots 12 are directly below, the rotary table 2 stops rotating. Then, the electric push rod 4 is activated, which drives the injection tube 8 vertically into the container, thereby improving injection accuracy. When the metering pump 6 is started, the material inside the tank 3 can be transported to the container through the connecting pipe 7 and the injection pipe 8 to achieve filling. When the injection pipe 8 is filled and there is residue at the bottom, the electric push rod 4 can drive the injection pipe 8 to move vertically upward. The inner liner 14 and the injection pipe 8 work together to scrape off the residue at the bottom of the injection pipe 8. Then, the second motor 16 is started to drive the receiving hopper 15 to rotate to the bottom of the limiting cylinder 10 to receive the scraped residue, thereby avoiding contamination of the surface of the rotating table 2 and preventing the bottom of the injection pipe 8 from being blocked, thus improving the stability and safety of filling.

[0031] Secondly, the card block 19 is engaged in the middle of the card slot 20, which improves the stability and convenience of the installation of the inner liner 14, thus making it easier to disassemble and replace the inner liner 14. When the receiving hopper 15 rotates away from the inside of the mounting frame 9, the operator can take out the receiving box 21 for cleaning, thereby improving the convenience of maintenance.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
