A filling device with anti-overflow function

Abstract

This utility model relates to the field of filling equipment technology, specifically to a filling device with an anti-overflow function. It includes a movable shell with a lead screw and nut slidably connected inside. The height of the contact sensor can be adjusted by a sliding sleeve to accommodate different filling heights. When the sliding sleeve moves, it simultaneously drives the connecting rod, follower block, and movable sleeve to move. The movable sleeve then slides on the outer surface of the adjusting rod. After the sliding sleeve reaches the appropriate position, a positioning rod slides through a movable hole, inserting into one of the positioning slots to fix the follower block. This, in turn, fixes the positions of the connecting rod, sliding sleeve, and multiple contact sensors. The filling device then fills the container. When liquid touches the contact sensor, a signal is transmitted to the outside, stopping the filling and preventing liquid from overflowing from the container.

Description

Technical Field

[0001] This utility model relates to the field of filling equipment technology, specifically to a filling equipment with an anti-overflow function. Background Technology

[0002] Filling equipment is an important category of packaging machinery, mainly used for quantitative dispensing of materials such as liquids, pastes, powders and granules. According to the degree of automation, it can be divided into semi-automatic and fully automatic models. Core manufacturers include Shanghai Yezhen, Guangzhou Dayilong, Shandong Saite, etc. It is widely used in food, daily chemical, chemical, pharmaceutical and other industries, covering the filling needs of various materials such as beverages, daily chemical products, lubricants, and pharmaceuticals.

[0003] A search revealed that CN218258841U discloses "a milk filling device with anti-overflow function, including a base, a workbench fixedly connected to the top of the base, a placement structure inside the workbench, and a support plate fixedly connected to the top of the base. This anti-overflow milk filling device works by placing a milk bottle inside the placement slot, activating a hydraulic cylinder, which drives the output end to move a sliding plate downwards, allowing the bottom of the filling head to enter the milk bottle. This causes the outer wall of the anti-overflow block to enter the milk bottle, opening a one-way valve, allowing milk to enter the milk bottle through a delivery pipe, coil, and connecting pipe. When the milk bottle is nearly full, a contact sensor sends information to the controller to prompt the one-way valve to close, thus preventing milk from overflowing the milk bottle during filling."

[0004] The aforementioned patent prevents spillage by using a contact sensor to contact the liquid. However, the position of the contact sensor in the patent cannot be adjusted. Currently, the volume of liquid containers varies. If the contact sensor position is fixed, the sensor may come into contact with the liquid too early, resulting in insufficient liquid filling in the container and affecting the filling accuracy.

[0016] Beneficial effects

[0017] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0018] 1. The height of the contact sensor can be adjusted by sliding the sliding sleeve to adapt to the required filling height of different volumes. When the sliding sleeve moves, it will drive the connecting rod, follower block and moving sleeve to move simultaneously. Then, when the moving sleeve moves, it will slide on the outer surface of the adjusting rod.

Then the filling device fills the container. When the liquid touches the contact sensor, it transmits a signal to the outside, thereby stopping the filling of the liquid and preventing the liquid from overflowing from the container.

[0019] Second, the rotation of the lead screw can drive the lead screw nut and the filling device to move horizontally, which facilitates the alignment of the filling device with the container. The motor can drive the lead screw to rotate automatically. When the lead screw nut moves, it can slide on the circumferential surface of the horizontal rod through the limit hole, which improves the horizontal movement stability of the lead screw nut.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] See attached document Figure 1-7 A filling device with anti-overflow function includes a movable shell 1. A lead screw nut 3 is slidably connected inside the movable shell 1. A connecting rod 5 is fixedly connected to the lower end of the lead screw nut 3. A filling device 16 is fixedly connected to the lower end of the connecting rod 5. A sliding sleeve 4 is slidably connected to the circumferential surface of the filling device 16. Multiple contact sensors 10 are fixedly connected to the lower end of the sliding sleeve 4. A connecting rod 6 is fixedly connected to the upper end of the sliding sleeve 4. A follower block 20 is fixedly connected to the upper end of the connecting rod 6. Two mounting blocks 12 are fixedly connected to one end of the connecting rod 5. An adjusting rod 13 is fixedly connected to the adjacent ends of the two mounting blocks 12. A movable sleeve 15 is fixedly connected to one end of the follower block 20. The movable sleeve 15 is slidably connected to the outer surface of the adjusting rod 13. Multiple positioning grooves 14 are opened at one end of the adjusting rod 13. Movable holes are opened at one end of the follower block 20 and one end of the movable sleeve 15. A positioning rod 17 is slidably connected in the movable hole and is movably inserted into one of the positioning grooves 14.

[0032] In a specific embodiment of this utility model, the height of the contact sensor 10 can be adjusted by sliding the sliding sleeve 4 to adapt to the required filling height of different volumes. When the sliding sleeve 4 moves, it will simultaneously drive the connecting rod 6, the follower block 20 and the moving sleeve 15 to move. Then, when the moving sleeve 15 moves, it will slide on the outer surface of the adjusting rod 13. After the sliding sleeve 4 slides to the appropriate position, the positioning rod 17 is slid through the movable hole, so that the positioning rod 17 is inserted into one of the positioning slots 14, thereby fixing the follower block 20, thereby fixing the position of the connecting rod 6, the sliding sleeve 4 and the multiple contact sensors 10. Then, the container is filled by the filling device 16. After the liquid touches the contact sensor 10, it transmits a signal to the outside, thereby stopping the filling of the liquid and preventing the liquid from overflowing from the container.

[0033] Please refer to the details. Figure 1-7 The lower end of the connecting rod 5 is provided with a transmission groove 11. A transmission pipe 7 is fixedly connected inside the connecting rod 5. The transmission pipe 7 is fixedly connected to the filling device 16. A valve 8 is fixedly connected to the circumferential surface of the transmission pipe 7. A force-bearing block 18 is fixedly connected to one end of the positioning rod 17. A first spring 19 is sleeved on the circumferential surface of the positioning rod 17.

[0034] In this embodiment: the transmission tube 7 can be fixed by the transmission groove 11, and the transmission tube 7 and the filling device 16 are connected and communicated. After the contact sensor 10 contacts the signal, it will transmit the signal to the valve 8 to close it, thereby preventing liquid from entering the filling device 16 and preventing liquid from overflowing. The elastic pull of the first spring 19 can pull the force block 18, so that the positioning rod 17 can move and maintain the insertion.

[0035] Please refer to the details. Figure 1-7 The upper end of the follower block 20 is provided with a limiting groove 21, and the circumferential surface of the positioning rod 17 is fixedly connected to a limiting block 22. The limiting block 22 is slidably connected in the limiting groove 21. One end of the limiting block 22 is provided with a rotating groove, and a lever 23 is rotatably connected in the rotating groove through a rotating shaft. Two positioning plates 24 are fixedly connected to the upper end of the follower block 20.

[0036] In this embodiment: when the positioning rod 17 moves, it will simultaneously drive the limiting block 22 to slide in the limiting groove 21, thereby improving the horizontal movement stability of the positioning rod 17. When the limiting block 22 moves to the rightmost side of the limiting groove 21, the lever 23 is rotated to engage it between the two positioning plates 24, thereby fixing the positions of the limiting block 22 and the positioning rod 17.

[0037] Please refer to the details. Figure 1-7A ratchet 25 is fixedly connected to one end of the rotating shaft, a stabilizing block 26 is fixedly connected to one end of the limiting block 22, and a pawl 28 is rotatably connected to one end of the limiting block 22 via a rotating rod. The pawl 28 intermittently meshes with the ratchet 25. A second spring 27 is fixedly connected between the near ends of the stabilizing block 26 and the pawl 28. A paddle block 29 is fixedly connected to the circumferential surface of the pawl 28. A connecting flange 9 is fixedly connected to one end of the transmission pipe 7.

[0038] In this embodiment: when the shaft rotates, it synchronously drives the ratchet 25 to rotate. Then, through the intermittent engagement of the pawl 28 and the ratchet 25, the ratchet 25 can be prevented from rotating in the opposite direction. Through the elastic expansion of the second spring 27, the pawl 28 can be pushed so that the pawl 28 can maintain intermittent engagement with the ratchet 25. The pawl 28 can be easily moved by the lever 29. Through the above design, the rotation angle of the shaft and the lever 23 can be fixed to prevent the lever 23 from disengaging from the two positioning plates 24. The connecting flange 9 facilitates the tight connection between the transmission pipe 7 and the external pipe.

[0039] Please refer to the details. Figure 1-7 A lead screw 30 is rotatably connected between the inner walls of the two sides of the movable housing 1. A lead screw nut 3 is threaded onto the circumferential surface of the lead screw 30. A motor 2 is fixedly connected to one end of the movable housing 1. The output end of the motor 2 is fixedly connected to the lead screw 30. A horizontal rod 31 is fixedly connected between the inner walls of the two sides of the movable housing 1. A limit hole is opened at one end of the lead screw nut 3, and the lead screw nut 3 is slidably connected to the circumferential surface of the horizontal rod 31 through the limit hole.

[0040] In this embodiment: the rotation of the lead screw 30 can drive the lead screw nut 3 and the filling device 16 to move horizontally, which facilitates the alignment of the filling device 16 with the container. The motor 2 can drive the lead screw 30 to rotate automatically. When the lead screw nut 3 moves, it can slide on the circumferential surface of the horizontal rod 31 through the limiting hole, which improves the horizontal movement stability of the lead screw nut 3.

[0041] Working principle: The height of the contact sensor 10 can be adjusted by sliding the sliding sleeve 4 to adapt to the required filling height of different volumes. When the sliding sleeve 4 moves, it will drive the connecting rod 6, the follower block 20 and the moving sleeve 15 to move simultaneously. Then, when the moving sleeve 15 moves, it will slide on the outer surface of the adjusting rod 13. After the sliding sleeve 4 slides to the appropriate position, the positioning rod 17 is slid through the movable hole, so that the positioning rod 17 is inserted into one of the positioning slots 14, thereby fixing the follower block 20, thereby fixing the position of the connecting rod 6, the sliding sleeve 4 and the multiple contact sensors 10. Then, the filling device 16 fills the container. After the liquid touches the contact sensor 10, it transmits a signal to the outside, thereby stopping the filling of the liquid and preventing the liquid from overflowing from the container.
