Description

Technical Field

[0001] This utility model belongs to the field of packaging machine technology, specifically, it relates to a metering and filling device for a fully automatic vertical powder packaging machine. Background Technology

[0002] With the development of modern industry, automation and intelligent technologies have been widely applied in the packaging industry. As an important component of the packaging industry, the technological advancement of the metering and filling devices in fully automatic vertical powder packaging machines is of great significance for improving production efficiency, ensuring product quality, and reducing costs.

[0003] In the past, traditional powder packaging machines relied mainly on manual operation for metering and filling, which was not only time-consuming and labor-intensive, but also prone to problems such as inaccurate metering and low work efficiency. Due to the errors in manual operation, the final product quantity statistics also became complicated and prone to errors, failing to meet the needs of modern large-scale production.

[0004] In fully automatic vertical powder packaging machines, the metering and filling device is one of the key components. This device is responsible for accurately measuring the powder material and filling it into packaging bags. The accuracy of the metering directly affects product quality and the company's production costs. Therefore, developing an efficient and accurate metering and filling device is crucial for improving the performance of fully automatic vertical powder packaging machines. Utility Model Content

[0005] The main technical problem to be solved by this utility model is to provide a metering and filling device for a fully automatic vertical powder packaging machine with a simple overall structure, which can achieve precise quantitative filling in fully automatic powder packaging, save labor, improve production efficiency, and improve the effect of use.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A metering and filling device for a fully automatic vertical powder packaging machine includes a support frame, a fixed frame fixedly installed on the upper end of the support frame, a weighing sensor fixedly installed at each of the four corners of the fixed frame, the force-bearing end of the weighing sensor fixedly installed on the same mounting bracket, a hopper fixedly installed on the mounting bracket, a conveying mechanism provided at the upper end of the hopper, one end of the conveying mechanism extending into the interior of the hopper, and a stirring device fixedly installed on the conveying mechanism on the outer surface inside the hopper.

[0008] The following are further optimizations of the above technical solution by this utility model:

[0009] A sealing plate is fixedly installed on the end face of the mounting bracket away from the weighing sensor, and the hopper is fixedly installed in the middle of the sealing plate.

[0010] Further optimization: The hopper is configured in the shape of a funnel, with the large end of the hopper passing through the sealing plate and the small end of the hopper connected to a discharge pipe, which is connected to a control valve.

[0011] Further optimization: The sleeve is fixedly installed on the end face of the sealing plate away from the weighing sensor, and the sleeve is also located at the edge of the large opening of the hopper. A motor mounting plate is fixedly installed at the end of the sleeve away from the hopper.

[0012] Further optimization: The conveying mechanism includes a motor fixedly installed in the middle of the motor mounting plate. The motor output shaft is fixedly installed at the power output end of the motor. After the motor output shaft passes through the motor mounting plate and extends into the hopper, a conveying auger is fixedly installed thereon.

[0013] Further optimization: The outer diameter of the conveying auger is matched with the inner diameter of the discharge pipe.

[0014] Further optimization: The stirring device includes a mounting sleeve fixedly installed on the outer surface of the motor output shaft, and the mounting sleeve is also located inside the sleeve near the motor mounting plate.

[0015] Further optimization: A first connecting rod and a second connecting rod are fixedly installed on the outer surface of the mounting sleeve. A first inclined rod is fixedly installed at the end of the first connecting rod away from the motor, and a second inclined rod is fixedly installed at the end of the second connecting rod away from the motor. The end of the first inclined rod away from the mounting sleeve extends into the sleeve, and the end of the second inclined rod away from the mounting sleeve extends into the hopper.

[0016] Further optimization: A first stirring rod is fixedly installed at the end of the first inclined rod away from the mounting sleeve. The first stirring rod is arranged parallel to the inner wall of the hopper, and the end of the first stirring rod away from the first inclined rod extends to the middle position inside the hopper.

[0017] Further optimization: A second stirring rod is fixedly installed at the end of the second inclined rod away from the mounting sleeve. The second stirring rod is arranged parallel to the inner wall of the hopper. A rubber layer is adhered to the end face of the second stirring rod near the inner wall of the hopper, and the rubber layer is in contact with the inner wall of the hopper.

[0018] A third stirring rod is also fixedly installed at the connection between the second stirring rod and the second inclined rod. The third stirring rod is arranged parallel to the inner wall of the sleeve and extends upward into the inside of the sleeve.

[0019] This utility model adopts the above-mentioned technical solution, which is ingenious in conception and reasonable in structure. It can improve the filling accuracy of each bag of powder material during the powder material filling process, and realize full automation, save labor costs, and improve production efficiency and quality.

[0020] By pre-setting the weighing sensor, the overall weight of the sleeve and hopper is detected in real time. When the reduction in the overall weight of the sleeve and hopper reaches the pre-set value of the weighing sensor, the motor and control valve are shut off, achieving precise quantitative filling of powder materials and improving filling accuracy. In addition, a stirring device is set up to solve the problem of powder material adhesion and caking. At the same time, the inner wall of the hopper is scraped. By setting a rubber layer, the inner wall of the hopper is protected during the scraping process, extending its service life and making operation convenient.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0026] like Figure 1-3 As shown: A metering and filling device for a fully automatic vertical powder packaging machine includes a support 2, a fixed frame 3 fixedly installed on the upper end of the support 2, a weighing sensor 4 fixedly installed at each of the four corners of the fixed frame 3, the force-bearing end of the weighing sensor 4 fixedly installed on the same mounting bracket 5, a hopper 6 fixedly installed on the mounting bracket 5, a conveying mechanism 7 provided on the upper end of the hopper 6, one end of the conveying mechanism 7 extending into the interior of the hopper 6, and a stirring device 8 fixedly installed on the conveying mechanism 7 on the outer surface inside the hopper 6.

[0027] like Figure 1 As shown, in this embodiment, the bracket 2 is fixedly installed on the vertical packaging machine 1. The vertical packaging machine 1 is a commercially available powder packaging machine that can automatically fill and seal powder. Its specific working principle is well known and will not be described in detail here.

[0028] like Figure 2-3 As shown, the bracket 2 is made of multiple square tubes of the same length welded together, and the fixing frame 3 is made of multiple square tubes of different lengths welded together. At the same time, the fixing frame 3 is fixedly installed at the upper end of the bracket 2 by welding.

[0029] In this embodiment, the number of weighing sensors 4 is set to four, which are located at the four corners of the end face of the fixed frame 3 away from the bracket 2.

[0030] The weighing sensor 4 is fixedly mounted on the fixed frame 3 by bolts.

[0031] The mounting bracket 5 is made of C-shaped steel of different lengths welded together, and the mounting bracket 5 is fixedly installed on the force-bearing end of all the weighing sensors 4 by bolts and nuts.

[0032] With this design, the weighing sensor 4 can provide feedback on changes in the weight applied to the mounting bracket 5.

[0033] In this embodiment, the weighing sensor 4 is a commercially available model, and its specific weighing principle is well known and will not be described in detail here.

[0034] A sealing plate 51 is fixedly installed on the end face of the mounting bracket 5 away from the weighing sensor 4, and the hopper 6 is fixedly installed in the middle position of the sealing plate 51.

[0035] In this embodiment, the hopper 6 is configured in the shape of a funnel, with the large end of the hopper 6 penetrating through the sealing plate 51, and the small end of the hopper 6 connected to the discharge pipe 9.

[0036] The discharge pipe 9 is connected to a control valve 10, which is commercially available. The control valve 10 can control the falling of powder material in the hopper 6.

[0037] When the material in the hopper 6 needs to be poured, the control valve 10 is opened, and the powder material falls from the discharge pipe 9. When the material does not need to be poured, the control valve 10 is closed and the discharge pipe 9 is shut off, thus enabling quantitative filling.

[0038] The other end of the discharge pipe 9 is connected to the filling and conveying pipe in the vertical packaging machine 1 through a flexible connecting pipe.

[0039] The control terminal of the control valve 10 is connected to the control system wire of the vertical packaging machine 1 via an electric wire, and the control valve 10 is controlled by the control system.

[0040] The sleeve 72 is fixedly installed on the end face of the sealing plate 51 away from the weighing sensor 4, and the sleeve 72 is also located at the edge of the large opening of the hopper 6.

[0041] A motor mounting plate 73 is fixedly installed at the end of the sleeve 72 away from the hopper 6. Two symmetrically arranged feed inlets 74 are connected to the motor mounting plate 73 near the edge.

[0042] The other ends of the two feed ports 74 are connected to the storage device for powder materials via flexible connections, and the control output of the storage device is electrically connected to the control system via wires.

[0043] With this design, the powder material in the powder material storage device is conveyed through the feed inlet 74 to the sleeve 72 and the hopper 6 for filling and use.

[0044] The flexible connecting pipe is a lightweight flexible pipe, which is known in the prior art and will not be described in detail here.

[0045] The conveying mechanism 7 includes a motor 71 fixedly installed at the middle position of the motor mounting plate 73, and the control end of the motor 71 is electrically connected to the control system via wires.

[0046] The motor output shaft 75 is fixedly installed at the power output end of the motor 71. The motor output shaft 75 passes through the motor mounting plate 73 and extends into the hopper 6, where a conveying auger 76 is fixedly installed.

[0047] The output end of the conveying auger 76 extends into the discharge pipe 9 and is located above the control valve 10.

[0048] In this embodiment, the outer diameter of the conveying auger 76 matches the inner diameter of the discharge pipe 9.

[0049] With this design, when the motor 71 starts, the power output end of the motor 71 drives the motor output shaft 75 to rotate, which in turn drives the conveying auger 76 to rotate. During the rotation of the conveying auger 76, the powder material in the hopper 6 is conveyed to the discharge pipe 9, while preventing powder material outside the conveying auger 76 from falling into the discharge pipe 9 from the small opening end of the hopper 6, thus enabling control over the weight of the conveyed powder material.

[0050] The stirring device 8 includes a mounting sleeve 81 fixedly installed on the outer surface of the motor output shaft 75, and the mounting sleeve 81 is located inside the sleeve 72 near the motor mounting plate 73.

[0051] The first connecting rod 86 and the second connecting rod 87 are fixedly installed on the outer surface of the mounting sleeve 81 by bolts.

[0052] The positions of the first connecting rod 86 and the second connecting rod 87 on the mounting sleeve 81 are symmetrical about the central axis of the mounting sleeve 81.

[0053] A first inclined rod 82 is fixedly installed at the end of the first connecting rod 86 away from the motor 71, and a second inclined rod 84 is fixedly installed at the end of the second connecting rod 87 away from the motor 71.

[0054] The first inclined rod 82 has a smaller inclination relative to the horizontal than the second inclined rod 84 has a smaller inclination relative to the horizontal. The end of the first inclined rod 82 away from the mounting sleeve 81 extends into the sleeve 72, and the end of the second inclined rod 84 away from the mounting sleeve 81 extends into the hopper 6.

[0055] The first stirring rod 83 is fixedly installed at the end of the first inclined rod 82 away from the mounting sleeve 81, and the first stirring rod 83 is arranged parallel to the inner wall of the hopper 6.

[0056] The first stirring rod 83 extends from the end away from the first inclined rod 82 to the middle position inside the hopper 6.

[0057] The second inclined rod 84 is fixedly installed with a second stirring rod 85 at the end away from the mounting sleeve 81. The second stirring rod 85 is arranged parallel to the inner wall of the hopper 6.

[0058] A rubber layer 850 is adhered to one end face of the second stirring rod 85 near the inner wall of the hopper 6, and the rubber layer 850 is in contact with the inner wall of the hopper 6.

[0059] A third stirring rod 88 is also fixedly installed at the connection between the second stirring rod 85 and the second inclined rod 84. The third stirring rod 88 is arranged parallel to the inner wall of the sleeve 72 and extends upward into the inside of the sleeve 72.

[0060] With this design, the stirring device 8 can rotate following the motor output shaft 75 under the drive of the motor 71.

[0061] Due to the fine nature of powder materials, they are prone to caking and adhering to the inner walls of the sleeve 72 and the hopper 6. During the material conveying process of the conveying auger 76, the first stirring rod 83, the second stirring rod 85, and the third stirring rod 88 simultaneously stir and disperse the powder materials in the sleeve 72 and the hopper 6 to facilitate material conveying. At the same time, the rubber layer 850 scrapes the inner wall of the hopper 6 to prevent the material from adhering to the inner wall of the hopper 6. During the scraping process, the soft properties of the rubber layer 850 protect the inner wall of the hopper 6.

[0062] When the metering and filling device of the fully automatic vertical powder packaging machine is in use, the value of the weighing sensor 4 is preset through the control system of the vertical packaging machine 1.

[0063] In this embodiment, the weighing sensor 4 is preset with three values: a maximum value. When the storage device for storing powder materials conveys materials to the sleeve 72 and the hopper 6 through the feed port 74 via a flexible connection, when the weighing sensor 4 senses that the weight of the material in the sleeve 72 and the hopper 6 has reached the maximum value, it feeds the signal back to the control system, stops the storage device from continuing to convey materials, and completes the storage of materials in the sleeve 72 and the hopper 6.

[0064] One is the weight of each bag of powder material to be filled. After the sleeve 72 and the hopper 6 have finished storing the material, the vertical packaging machine 1 starts filling and sealing the material. The control system controls the motor 71 to start and the control valve 10 to open. The power output end of the motor 71 drives the motor output shaft 75 to rotate, which drives the conveying auger 76 to rotate. The conveying auger 76 starts to convey the material. At this time, the control valve 10 is open, and the material enters the filling and conveying pipe from the discharge pipe 9 through the flexible connection pipe for filling. During the material falling process, the overall weight of the sleeve 72 and the hopper 6 will be reduced. When the reduction reaches the preset weight of each bag of powder material to be filled, the weighing sensor 4 feeds the signal back to the control system. The control system controls the control valve 10 and the motor 71 to close, stopping the falling and conveying of material. This process is repeated. By controlling the signal of the lost weight through the weighing sensor 4, the material is accurately falling, achieving precise quantitative filling and improving the weight accuracy of each bag of powder material.

[0065] The last value is the minimum value: when the total weight of the sleeve 72 and the hopper 6 detected by the weighing sensor 4 reaches the minimum value, the signal is fed back to the control system, which then controls the start of the external storage device to continue to transport powder material into the feed inlet 74 for the next storage.

[0066] The entire filling device achieves fully automated quantitative material feeding, saving labor costs and improving filling accuracy.

[0067] In addition to this embodiment, the filling device can also be applied to other types of powder packaging machines, thus expanding its application range.

[0068] For those skilled in the art, any changes, modifications, substitutions, and variations made to the embodiments based on the teachings of this utility model, without departing from the principles and spirit of this utility model, still fall within the protection scope of this utility model.
