[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-4 The present invention provides an embodiment of a fully automatic filling machine with adjustable capacity, comprising a conveying device 1, a storage tank 5, and a control box 7. The storage tank 5 is located at the center of the upper end face of the conveying device 1 on one side, and the control box 7 is located at the center of the front end face of the conveying device 1 on one side. An inspection light box 6 is fixedly connected to the upper end face of the conveying device 1 on one side of the storage tank 5, and a lifting filling structure 2 is fixedly connected to the upper end face of the conveying device 1 at the lower end of the storage tank 5. The lifting filling structure 2 helps to prevent the influence of vibration.

[0031] The lifting and pouring structure 2 includes a frame 201. Synchronous pulleys 206 are rotatably connected to both ends of the upper surface of the frame 201. A transmission worm gear 205 is fixedly connected to the upper end of the front synchronous pulley 206. A servo motor 202 is fixedly connected to one side wall of the frame 201 near the front synchronous pulley 206. A transmission worm gear 203 is fixedly connected to the output end of the servo motor 202. A mounting base 204 is sleeved on the other end of the transmission worm gear 203 and fixedly connected to the frame 201. Synchronous belts 207 are sleeved on the outer walls of the two synchronous pulleys 206. The lower ends of both synchronous pulleys 206 penetrate the upper surface of the frame 201 and extend into the interior of the frame 201, and both ends are fixed. The system is connected to lead screws 208, and lifting plates 210 are threaded onto the outer walls of the two lead screws 208. Through holes 212 are opened at the center of the upper end face of the lifting plate 210 and the center of the upper end face of the frame 201. A metering pump 211 is fixedly connected to the center of the lower end face of the lifting plate 210. Due to the vibration generated by the equipment acting on the frame 201, the transmission worm 203 will not rotate due to the self-locking property of the servo motor 202. Furthermore, the self-locking property between the transmission worm wheel 205 and the transmission worm 203 ensures that the lead screw 208 at the front will not rotate. The synchronous belt 207 prevents the synchronous pulley 206 at the rear from rotating, thereby preventing the two lead screws 208 from rotating and facilitating the prevention of the impact of vibration.

[0032] The front and rear inner walls of the conveying device 1 located on one side of the lifting and filling structure 2 are provided with grooves 4 at the upper part. The grooves 4 are provided with positioning structures 3, which facilitates positioning and limiting of filling bottles of different diameters.

[0033] The positioning structure 3 includes two rotating plates 301, which are rotatably connected to the interiors of two grooves 4. A second connecting seat 304 is provided at one side of the center of the front end face of the front rotating plate 301 and at one side of the center of the rear end face of the rear rotating plate 301. A first connecting seat 302 is provided at one side of the center of the front inner wall of the front groove 4 and at one side of the rear end face of the rear groove 4. An electric telescopic rod 303 is rotatably connected to the rear end face of the front first connecting seat 302 and the front end face of the rear first connecting seat 302. The two electric telescopic rods 303 are rotatably connected to the front end face of the front second connecting seat 304 and the rear end face of the rear second connecting seat 304, respectively. By controlling the extension of the two electric telescopic rods 303, the two rotating plates 301 are pushed toward the center position, thereby limiting the empty bottle on the conveying device 1.

[0034] Each of the two rotating plates 301 has a slot 305 on one end of its upper surface. Each slot 305 contains a locking block 306. One end of each locking block 306 passes through the slot 305 and extends to one side of the two rotating plates 301, with a limiting plate 307 fixedly connected to each end. Limiting bolts 308 are provided on the upper part of the rear end face of the rear rotating plate 301 and the upper part of the front end face of the front rotating plate 301, respectively. These limiting bolts 308 pass through the rear end face of the rear rotating plate 301 and the front end face of the front rotating plate 301, respectively, and extend into the slots 305, with their ends respectively abutting one end of each locking block 306. When using bottles of different diameters, the two limiting bolts 308 are rotated in the opposite direction to release the limiting of the two locking blocks 306, and the two limiting plates 307 are pulled out. Then, the two locking blocks 306 at one end of the corresponding two limiting plates 307 are inserted into the two locking slots 305. Then, the two limiting bolts 308 are rotated in the forward direction, and the ends of the two limiting bolts 308 are attached to the two locking blocks 306, increasing the friction between the two locking blocks 306 and the two locking slots 305, which makes it easier to fix the two locking blocks 306. This makes it easy to adjust the limiting according to the diameter of the bottle, so that the bottle mouth is always located below the oil filling port.

[0035] An oil receiving structure 8 is fixedly connected to the upper end face of the conveying device 1 located on one side of the frame 201. The oil receiving structure 8 includes a column 801. A sleeve 803 is fixedly connected to the upper center of the end face of the column 801. A sliding rod 806 is slidably connected inside the sleeve 803. One end of the sliding rod 806 passes through the sleeve 803 and extends to one side of the sleeve 803. A storage box 808 is fixedly connected to the end of the sliding rod 806. A drain valve 809 is fixedly connected to the center of the lower end face of the storage box 808. After use, the equipment is powered off, and the storage box 808 is moved to the lower end of the oil nozzle. This allows the oil droplets remaining inside the oil nozzle at the output end of the metering pump 211 to fall into the storage box 808. The collected oil is then discharged through the drain valve 809, preventing oil droplets from falling onto the conveying device 1.

[0036] An electromagnet 802 is fixedly connected to one end face of the inner column 801 of the sleeve 803. A connecting rod 805 is fixedly connected to one end face of the sliding rod 806. A permanent magnet 804 is fixedly connected to the other end of the connecting rod 805. A spring body 807 is sleeved on the outside of the connecting rod 805. One end of the spring body 807 is fixedly connected to one end face of the sliding rod 806, and the other end of the spring body 807 is fixedly connected to one end face of the column 801. When used again, the electromagnet 802 is energized, and the storage box 808 is pushed. The storage box 808 pushes the sliding rod 806 and the connecting rod 805 into the sleeve 803, so that the permanent magnet 804 is attached to the electromagnet 802, thereby preventing the spring body 807 from pushing the storage box 808 out.

[0037] A spring tube 209 is fixedly connected to the input end of the metering pump 211. The input end of the spring tube 209 is fixedly connected to the output end of the storage tank 5, so that the oil volume can be transferred through the spring tube 209 during the rising and falling process of the metering pump 211 without being affected.

[0038] Working principle: In use, the empty bottle on the conveyor 1 is moved to the lower end of the storage tank 5 by controlling the start of the conveyor device 1. After being blocked by the two limit plates 307, the conveyor device 1 stops. The servo motor 202 is then started in the forward direction. The servo motor 202 drives the transmission worm gear 203 to rotate, which in turn drives the transmission worm wheel 205 to rotate. The transmission worm wheel 205 drives the front synchronous pulley 206 to rotate, which in turn drives the rear synchronous pulley 206 to rotate via the synchronous belt 207. This causes the two synchronous pulleys 206 to rotate, which in turn drives the lead screw 208 to rotate synchronously, causing the lifting plate 210 to move downward, thereby inserting the oil filling nozzle into the empty bottle. Then, the metering pump 211 is started to fill the bottle with oil.

[0039] During the oil filling process, the vibration generated by the equipment acts on the frame 201. Due to the self-locking property of the servo motor 202, the transmission worm 203 will not rotate. Furthermore, the self-locking property between the transmission worm wheel 205 and the transmission worm 203 ensures that the lead screw 208 at the front will not rotate. The synchronous belt 207 prevents the synchronous pulley 206 at the rear from rotating, thereby preventing the two lead screws 208 from rotating and facilitating the prevention of the impact of vibration. After the oil filling is completed, the servo motor 202 is controlled to start in reverse, driving the metering pump 211 to move upward.

[0040] Then, control the conveyor device 1 to move the filled bottle to one side. If it is used for filling bottles of different diameters, rotate the two limit bolts 308 in the opposite direction to release the limit on the two locking blocks 306, pull out the two limit plates 307, and then insert the two locking blocks 306 at one end of the corresponding two limit plates 307 into the two locking slots 305. Then rotate the two limit bolts 308 in the forward direction, and the ends of the two limit bolts 308 will fit against the two locking blocks 306, increasing the friction between the two locking blocks 306 and the two locking slots 305, which makes it easier to fix the two locking blocks 306. This makes it easier to adjust the limit according to the diameter of the filling bottle, so that the bottle mouth is always located below the filling port.

[0041] After use, the equipment is powered off. The electromagnet 802 loses its magnetism, causing the spring body 807 to move to one side, thereby moving the storage box 808 to the lower end of the oil nozzle. This allows any residual oil droplets inside the oil nozzle at the output end of the metering pump 211 to fall into the storage box 808. When used again, the electromagnet 802 is powered on, and the storage box 808 is pushed again. This causes the storage box 808 to push the sliding rod 806 and the connecting rod 805 into the sleeve 803, thereby causing the permanent magnet 804 to adhere to the electromagnet 802. This prevents the spring body 807 from pushing the storage box 808 out, and the collected oil is then discharged through the drain valve 809, preventing oil droplets from falling onto the conveying device 1.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
