Description

Technical Field

[0001] The utility model belongs to the technical field of packaging machines, and in particular relates to an automatic liquid packaging machine capable of sorting. Background Art

[0002] In the existing technology, liquid packaging machines are widely used in food, chemical and other industries. Liquid packaging machines can automatically fill liquid products into packaging containers according to the set filling capacity, and the filling process is stable, which can meet the filling needs of different products.

[0003] Liquid packaging machines use a series of mechanical and electrical devices to work together to complete the processes of filling, sealing, cutting, and packaging liquids. These devices include storage tanks, metering devices, filling devices, sealing devices, and cutting devices. Before filling, the liquid in the storage tank is transported to the metering device through a pipe. The metering device accurately measures the amount of liquid through sensors and control systems to ensure the accurate amount of liquid in each packaging unit. During the filling process, when the liquid in the metering device reaches the preset amount, the filling device starts working. The filling device usually includes one or more filling heads, which inject the liquid from the metering device into the packaging bag or container. During the filling process, the control system monitors the flow rate and speed of the liquid to ensure the accuracy and stability of the filling. After filling, sealing and cutting are carried out. After filling, the sealing device will seal the packaging bag or container. There are various sealing methods, such as heat sealing and cold sealing, depending on the requirements of the packaging material and product. At the same time, the cutting device will cut the packaging bag to separate it from the next packaging bag and prepare it for the next packaging unit.

[0004] Typically, after cutting, the packaging bags are directly printed with the production date or labeled, which cannot guarantee whether the weight of each bag is qualified, affecting the quality of use; or they are manually sorted, and those that do not meet the weight requirements are sorted out. This process is tedious and complicated, increases the labor intensity of workers, and affects the packaging efficiency of the bags. Utility Model Content

DETAILED DESCRIPTION

[0028] like Figure 1-3 As shown: An automated liquid packaging machine capable of sorting, comprising a filling device 2 and a feeding device 1 for feeding the filling device 2, a conveying and sorting device 3 being provided at the output end of the filling device 2, and a placement component 4 being provided at the output end of the conveying and sorting device 3;

[0029] The filling device 2 includes a filling bracket 22, a storage tank 21 is fixedly installed above the filling bracket 22, an upper material level sensor 24 is provided above the outer surface of the storage tank 21, and a lower material level sensor 25 is provided below the outer surface of the storage tank 21. The detection ends of the upper material level sensor 24 and the lower material level sensor 25 both penetrate into the interior of the storage tank 21;

[0030] The outlet of the storage tank 21 is connected to a rotor pump servo motor 23, which is also fixedly mounted on a filling bracket 22. The output end of the rotor pump servo motor 23 is connected to a filling pipe 26. A packaging bag making mechanism 27 is also provided in the filling bracket 22 at a position corresponding to the filling pipe 26.

[0031] The conveying and sorting device 3 includes an oblique conveying mechanism 31 provided at the discharge port of the filling device 2 , a transverse re-inspection conveying mechanism 32 is provided at the output end of the oblique conveying mechanism 31 , and a sorting device 33 is provided at the output end of the transverse re-inspection conveying mechanism 32 .

[0032] like Figure 2As shown, the feeding device 1 includes a material pool 11 placed on the ground, a fixed bracket is fixedly installed on the material pool 11, and a feeding pump 12 is fixedly installed on the fixed bracket. The discharge port of the feeding pump 12 is connected to a feeding pipe 13, and one end of the feeding pipe 13 is also connected to the material pool 11, and the other end of the feeding pipe 13 is connected to the storage tank 21. When feeding, start the feeding pump 12, and the feeding pipe 13 will pump the liquid material in the material pool 11 into the storage tank 21 to complete the feeding.

[0033] like Figure 1 As shown, the upper material level sensor 24 and the lower material level sensor 25 can detect the liquid level in the storage tank 21. When the liquid level in the storage tank 21 reaches the upper material level sensor 24, the loading pump 12 can be stopped to complete the loading of the storage tank 21.

[0034] When the liquid level in the storage tank 21 reaches the lower material level sensor 25 during use, the loading pump 12 can be started to continue loading the storage tank 21, which is convenient to control.

[0035] The filling pipe 26 is also connected to a filling valve, which is not shown in the figure. The filling valve can control the falling of the liquid material in the storage tank 21 to assist in achieving the effect of quantitative filling.

[0036] The packaging bag making mechanism 27 includes a vertical sealing module 270 disposed on the outer surface of the filling tube 26 .

[0037] In this embodiment, the packaging bags made by the packaging bag making mechanism 27 are made of EVA film.

[0038] The vertical sealing module 270 can wrap the EVA film on the outer surface of the filling pipe 26 and perform vertical sealing.

[0039] A longitudinal film stretcher 271 is fixedly installed on the filling bracket 22 below the vertical sealing module 270. The longitudinal film stretcher 271 can longitudinally stretch the vertically sealed EVA film to fit the shape and size of the package.

[0040] An upper clamping plate 272 is provided on the filling bracket 22 below the longitudinal film stretcher 271 , and the upper clamping plate 272 can plastic-seal the upper transverse end of the EVA film that has been longitudinally stretched.

[0041] A transverse sealing and cutting module 273 is fixedly installed on the filling bracket 22 below the upper clamping plate 272. The transverse sealing and cutting module 273 can perform plastic sealing and cutting on the transverse lower end of the EVA film.

[0042] In this embodiment, the packaging bag making mechanism 27 adopts the bag making structure of the fully automatic powder packaging machine\powder packaging machine\powder material packaging machine (ZK-240F) produced by Guangzhou Zhongkai Packaging Special Machinery Co., Ltd. The specific structures and working principles of the vertical sealing module 270, longitudinal film pulling device 271, upper splint 272, and horizontal sealing cutting module 273 are all known and can be purchased directly, so they will not be described in detail here.

[0043] A film feeding frame 274 is fixedly installed at one side of the filling bracket 22 and at a position corresponding to the filling pipe 26. A film feeding motor 275 is fixedly installed below the film feeding frame 274. The film feeding motor 275 can stretch out the rolled EVA film and transport it to the position of the vertical sealing module 270. Its specific structure and connection method are the same as those in the fully automatic powder packaging machine\powder packaging machine\powder packaging machine (ZK-240F) produced by Guangzhou Zhongkai Packaging Special Machinery Co., Ltd., and will not be repeated here.

[0044] A filling control system for controlling the operation of the filling device 2 is also provided at the other side of the filling bracket 22. The control end of the loading pump 12, the signal output ends of the loading level sensor 24 and the loading level sensor 25, the control end of the rotor pump servo motor 23, and the signal input end of the filling valve are all connected to the control system wires.

[0045] During filling, the filling control system controls the pulse number of the rotor pump servo motor 23. During this period, the filling valve is opened and the liquid material falls from the filling pipe 26 into the packaging bag. When the pulse number of the rotor pump servo motor 23 reaches a preset value, the filling control system controls to stop the rotor pump servo motor 23 and close the filling valve, thereby completing the quantitative filling of a bag of liquid material and improving the filling quality and efficiency.

[0046] Each bag of liquid material that has been filled and sealed falls onto the inclined conveying mechanism 31 .

[0047] The inclined conveying mechanism 31 includes a first bracket 310 , which is located near the outlet of the filling pipe 26 .

[0048] A first conveyor belt 311 is fixedly mounted on the first bracket 310 . A first motor 312 is fixedly mounted at the end of the first bracket 310 away from the filling bracket 22 . The power output end of the first motor 312 is fixedly connected to the control end of the first conveyor belt 311 .

[0049] The first motor 312 is started to drive the first conveyor belt 311 to operate. The specific control and driving principle thereof is well known in the prior art and will not be described in detail here.

[0050] In this way, the liquid material bags that have been filled and sealed all fall onto the first conveyor belt 311 , and are conveyed to the transverse re-inspection conveying mechanism 32 by the conveying action of the first conveyor belt 311 .

[0051] The transverse re-inspection conveying mechanism 32 includes a second bracket 320 . The second bracket 320 is located at an end of the first bracket 310 away from the filling bracket 22 .

[0052] A second conveyor belt 321 is fixedly installed on the second bracket 320 at a position close to one end of the first bracket 310 .

[0053] The operating principle of the second conveyor belt 321 is the same as that of the first conveyor belt 311 and is driven by a motor.

[0054] The bagged material bags on the first conveyor belt 311 are conveyed to the second conveyor belt 321 .

[0055] A re-inspection scale 322 is fixedly installed on the second bracket 320 near the second conveyor belt 321, and a re-inspection scale control system 323 is fixedly installed on one side of the second bracket 320 at a position corresponding to the re-inspection scale 322. The re-inspection scale control system 323 can control the operation of the re-inspection scale 322.

[0056] The re-inspection scale 322 is composed of a weighing sensor and a weighing conveyor belt. The weighing conveyor belt runs slowly and can weigh and convey the bagged materials. That is, when the bagged materials are conveyed to the re-inspection scale 322, the weight of each bag of bagged materials can be displayed and recorded on the re-inspection scale control system 323, and then the bagged materials are conveyed to the sorting device 33.

[0057] In this embodiment, the re-inspection scale control system 323 is also provided with a communication interface, through which the MES system can be remotely connected, and then the weight standard of each bag of liquid material required in the re-inspection scale control system 323 can be remotely set, and the filled bagged materials can be re-inspected according to this weight standard, thereby realizing humanized operation.

[0058] The principle of connecting to the MES system through a communication interface and the principle of remotely issuing instructions through the MES system are well known in the prior art and will not be described in detail here.

[0059] like Figure 2-3 As shown together, the sorting device 33 includes a third bracket 330 , and the third bracket 330 is located at one end of the second bracket 320 .

[0060] A third conveyor belt 331 is fixedly installed at one end of the third bracket 330 close to the second bracket 320. The operation mode of the third conveyor belt 331 is the same as that of the second conveyor belt 321. At the same time, the bagged materials output from the re-inspection scale 322 are conveyed to the third conveyor belt 331.

[0061] A fourth conveyor belt 333 is rotatably mounted on the third bracket 330 near the third conveyor belt 331 . The operation mode of the fourth conveyor belt 333 is the same as that of the third conveyor belt 331 , and will not be described in detail herein.

[0062] A rotating shaft is fixedly installed at the middle position of the fourth conveyor belt 333 along the width direction of the fourth conveyor belt 333 (not shown in the figure). The rotating shaft is also rotatably installed on the third bracket 330.

[0063] A flip motor 332 is fixedly mounted on one end of the rotating shaft, and the flip motor 332 is also fixedly mounted on the third bracket 330 .

[0064] With this design, the turning motor 332 can drive the fourth conveyor belt 333 to rotate counterclockwise.

[0065] The control end of the flip motor 332 is electrically connected to the re-inspection scale control system 323 .

[0066] A defective product storage box 334 is movably placed on the third bracket 330 below the fourth conveyor belt 333 .

[0067] When the re-inspection scale 322 detects a bagged material package that does not meet the weight requirements, it transmits a signal to the flip motor 332. When the unqualified bagged material is conveyed to the fourth conveyor belt 333, the flip motor 332 rotates, driving the fourth conveyor belt 333 to rotate counterclockwise, that is, flipping the unqualified bagged material on the fourth conveyor belt 333 and dropping it into the unqualified product storage box 334.

[0068] The placement assembly 4 includes a fourth bracket 41 . The fourth bracket 41 is located at one end of the third bracket 330 away from the re-inspection scale 322 . A qualified product placement box 42 is movably placed on the fourth bracket 41 .

[0069] When the re-inspection scale 322 detects that the bagged material packaging is qualified in weight, the re-inspection scale control system 323 controls not to start the flip motor 332, and the bagged material with qualified weight falls into the qualified product placement box 42 through the third conveyor belt 331 and the fourth conveyor belt 333.

[0070] In this way, the sorting can be completed, and the staff can then process the bagged materials in the qualified product placement box 42 and the unqualified product storage box 334 respectively, which saves the labor intensity of the staff and improves the packaging quality of the liquid material.

[0071] For ordinary technicians in this field, based on the teachings of this utility model, without departing from the principles and spirit of this utility model, changes, modifications, replacements and deformations made to the implementation methods are still within the scope of protection of this utility model.
