Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a fine powder packaging machine. Background Technology

[0002] Powder packaging machines are suitable for quantitative packaging of powdered, granular, and solid materials in industries such as traditional Chinese medicine, food, and agricultural products. Currently, there are various types of powder packaging machines designed for different powders. Most existing packaging machines will spill a small amount of powder onto the operating plate after the powder is added. The more times the powder is added, the more powder will spill, resulting in some waste.

[0003] To address the aforementioned technical issues, a patent document with publication number (CN219097032U) discloses a powder packaging machine, comprising components such as a base frame, support frame, top plate, operating panel, connecting blocks, and a collection box. The support frame is fixedly connected to one side of the upper end of the base frame, and the top plate is fixedly connected to the upper end of the support frame. The operating panel is fixedly connected to the middle of one side of the support frame, and connecting blocks are fixedly connected to both sides of the lower middle of the operating panel. A collection box is slidably connected to the inner walls of the two connecting blocks, and a handle is fixedly connected to the middle of one side of the collection box. This invention achieves quantitative dispensing through the equidistant rotation of a screw. When powder is dispensed, any scattered powder falls through a strainer into the collection box. When the collection box accumulates a certain amount of powder, the remaining powder can be poured into a storage tank for reuse, avoiding waste and maintaining the cleanliness of the operating table.

[0004] However, in the aforementioned existing technologies, the quantitative dispensing method using the equidistant rotation of the screw has low accuracy and is not convenient for controlling the weight of powder dispensed each time. Utility Model Content

[0005] The purpose of this invention is to provide a fine powder packaging machine, which aims to solve the technical problems of low accuracy and difficulty in controlling the weight of powder dispensed each time by using the equidistant rotation of the screw for quantitative dispensing in the existing technology.

[0006] To achieve the above objectives, this utility model employs a fine powder packaging machine, comprising a base plate and a packaging mechanism. The packaging mechanism includes a support column, a tank, a solenoid valve, a table, a weighing scale, two electric telescopic rods, a placement plate, two frames, a moving assembly, and a stirring assembly. The support column is fixedly connected to the base plate and located on its upper surface. The tank is fixedly connected to the support column. The table is fixedly connected to the base plate and located on its upper surface. The weighing scale is positioned on the upper surface of the table. One end of each of the two electric telescopic rods is fixedly connected to the table, and the other end is fixedly connected to the moving assembly. The placement plate is fixedly connected to the moving assembly and has two rectangular slots. The two frames are respectively positioned inside the two rectangular slots. The stirring assembly is positioned inside the tank.

[0007] The movable component includes a mounting frame, a lead screw, a first motor, and a movable plate. The mounting frame is fixedly connected to two of the electric telescopic rods. One end of the movable plate is fixedly connected to the placement plate, and the other end of the movable plate passes through the mounting frame and is slidably connected to the mounting frame. The lead screw passes through the movable plate and is threadedly engaged with the movable plate. Both ends of the lead screw are rotatably connected to the mounting frame. The first motor is located at one end of the mounting frame, and the output end of the first motor is fixedly connected to the lead screw.

[0008] The stirring assembly includes a dual-axis motor, a rotating roller, multiple stirring rods, a cam, and a vibrating element. The dual-axis motor is located on the upper surface of the tank. The output end of the dual-axis motor is fixedly connected to the rotating roller and the cam, respectively. The multiple stirring rods are fixedly connected to the rotating roller, and the vibrating element is located on the outside of the tank.

[0009] The vibrating component includes a support frame, two connecting frames, two striking blocks, and two sets of guides. The support frame is sleeved on the outside of the cam. The two connecting frames are fixedly connected to the support frame, and the two striking blocks are fixedly connected to the two connecting frames. The two sets of guides are symmetrically arranged on the outside of the tank.

[0010] Each set of guide components includes a guide rod and a limiting block. The guide rod passes through the corresponding connecting frame and is slidably connected to the connecting frame. One end of the guide rod is fixedly connected to the tank body, and the other end of the guide rod is fixedly connected to the limiting block.

[0011] This utility model discloses a fine powder packaging machine. One end of each of the two electric telescopic rods is fixedly connected to a table, and the other end is fixedly connected to a moving assembly. The placement plate has two rectangular slots, and two frames are respectively disposed inside the two rectangular slots. In actual use, the packaging bag is placed inside the two frames. The two electric telescopic rods drive the moving assembly downwards, which in turn moves the placement plate downwards. The placement plate then moves the two frames downwards, placing one of the frames onto a weighing scale. After tareing the scale, the solenoid valve is opened, causing the powder in the container to fall into the frame. Inside the packaging bag, once the desired weight is reached, the solenoid valve closes. Then, the two electric telescopic rods drive the moving assembly upwards, which in turn moves the placement plate upwards. The placement plate then moves the two frames upwards. Next, the moving assembly drives the placement plate laterally, which in turn moves the two frames, positioning one frame above the weighing scale. This process is repeated to improve packaging efficiency. The weighing scale can dispense powder weighing from 0.1 to 0.3 grams. This method effectively solves the problems of low accuracy and difficulty in controlling the weight of powder dispensed each time in existing technologies that use equidistant screw rotation for quantitative dispensing.

[0021] This utility model provides a fine powder packaging machine, including a base plate 101 and a packaging mechanism. The packaging mechanism includes a support column 102, a tank 103, a solenoid valve 104, a table 105, a weighing scale 106, two electric telescopic rods 107, a placement plate 108, two frames 110, a moving component, and a stirring component. The moving component includes a mounting frame 111, a lead screw 112, a first motor 113, and a moving plate 114. The stirring component includes a dual-shaft motor 115, a rotating roller 116, multiple stirring rods 117, a cam 118, and a vibrating element. The vibrating element includes a support frame 119, two connecting frames 120, two striking blocks 121, and two sets of guides. Each set of guides includes a guide rod 122 and a limiting block 123. The aforementioned solution solves the problem in the prior art that the quantitative dispensing method using equidistant rotation of a screw has low accuracy and is inconvenient to control the weight of powder dispensed each time.

[0022] In this specific embodiment, the support column 102 is fixedly connected to the base plate 101 and located on the upper surface of the base plate 101. The tank 103 is fixedly connected to the support column 102. The table 105 is fixedly connected to the base plate 101 and located on the upper surface of the base plate 101. The weighing scale 106 is disposed on the upper surface of the table 105. One end of each of the two electric telescopic rods 107 is fixedly connected to the table 105, and the other end of each of the two electric telescopic rods 107 is fixedly connected to the moving component. The placement plate 108 is fixedly connected to the moving component. The placement plate 108 has two rectangular slots 109. Two frames 110 are respectively disposed inside the two rectangular slots 109. The stirring component is disposed inside the tank 103. In actual use, the packaging bag is placed inside the two frames 110, and the moving component is moved downward by the two electric telescopic rods 107. The placement plate 108 moves downward, causing the two frames 110 to move downward as well, placing one of the frames 110 on the weighing scale 106. After the weighing scale 106 is tare, the solenoid valve 104 is opened, causing the powder in the can 103 to fall into the packaging bag in the frame 110. When the desired weight is reached, the solenoid valve 104 closes, and then the two electric telescopic rods 107 drive the moving assembly to move upward. The moving assembly drives the placement plate 108 to move upward, and the placement plate 108 drives the two frames 110 to move upward. Then, the moving assembly drives the placement plate 108 to move laterally, and the placement plate 108 drives the two frames 110 to move, so that the other frame 110 is above the weighing scale 106. The above steps are repeated to improve packaging efficiency. The weighing scale 106 can dispense and package powder weighing from 0.1 grams to 0.3 grams.

[0023] The mounting frame 111 is fixedly connected to two electric telescopic rods 107. One end of the moving plate 114 is fixedly connected to the placement plate 108, and the other end of the moving plate 114 passes through the mounting frame 111 and is slidably connected to the mounting frame 111. The lead screw 112 passes through the moving plate 114 and is threadedly engaged with the moving plate 114. Both ends of the lead screw 112 are rotatably connected to the mounting frame 111. The first motor 113 is located at one end of the mounting frame 111, and the output end of the first motor 113 is fixedly connected to the lead screw 112. In actual use, the first motor 113 is started, and the output end of the first motor 113 drives the lead screw 112 to rotate, causing the moving plate 114 to move, which in turn drives the placement plate 108 to move.

[0024] Secondly, the dual-axis motor 115 is disposed on the upper surface of the tank 103. The output end of the dual-axis motor 115 is fixedly connected to the rotating roller 116 and the cam 118 respectively. Multiple stirring rods 117 are fixedly connected to the rotating roller 116 respectively. The vibrating element is disposed on the outside of the tank 103. In actual use, the dual-axis motor 115 is started. One output end of the dual-axis motor 115 drives the rotating roller 116 to rotate. The rotating roller 116 drives multiple stirring rods 117 to rotate, thereby stirring the powder in the tank 103 and preventing the powder from clumping. At the same time, the other output end of the dual-axis motor 115 drives the cam 118 to rotate. The cam 118 pushes against the vibrating element to move, thereby vibrating the tank 103 and preventing the powder from clogging.

[0025] Meanwhile, the supporting frame 119 is sleeved on the outside of the cam 118, the two connecting brackets 120 are fixedly connected to the supporting frame 119 respectively, the two striking blocks 121 are fixedly connected to the two connecting brackets 120 respectively, and the two sets of guide members are symmetrically arranged on the outside of the tank body 103. In actual use, the cam 118 rotates to support the supporting frame 119 and moves left and right, the supporting frame 119 drives the two connecting brackets 120 to move left and right, and the two connecting brackets 120 respectively drive the two striking blocks 121 to repeatedly strike the tank body 103.

[0026] In addition, the guide rod 122 passes through the corresponding connecting frame 120 and is slidably connected to the connecting frame 120. One end of the guide rod 122 is fixedly connected to the tank body 103, and the other end of the guide rod 122 is fixedly connected to the limiting block 123. In actual use, the abutment frame 119 moves to drive the connecting frame 120 to slide on the guide rod 122, thereby guiding the connecting frame 120, and limiting the connecting frame 120 through the limiting block 123.

[0027] In the specific use of the fine powder packaging machine of this embodiment, packaging bags are placed inside the two frames 110 respectively. The mounting frame 111 is moved downwards by the two electric telescopic rods 107. The mounting frame 111 moves downwards by the moving plate 114, which in turn moves the placement plate 108 downwards. The placement plate 108 moves the two frames 110 downwards, thus placing one of the frames 110 onto the weighing scale 106. After tareing the weighing scale 106, the solenoid valve 104 is opened, causing the powder in the can 103 to fall into the packaging bag in the frame 110. When the desired weight is reached, the solenoid valve 104 closes. Then, the two electric telescopic rods 107 move the mounting frame 111 upwards. The mounting frame 111 is moved upwards by the moving plate 114. The moving plate 114 drives the placement plate 108 to move upward, and the placement plate 108 drives the two frames 110 to move upward. Then, the first motor 113 is started, and the output end of the first motor 113 drives the lead screw 112 to rotate, causing the moving plate 114 to move. The moving plate 114 drives the placement plate 108 to move laterally, and the placement plate 108 drives the two frames 110 to move, so that the other frame 110 is above the weighing scale 106. Then, the above steps are repeated, which can improve packaging efficiency. The weighing scale 106 can dispense and package powder weighing 0.1 grams to 0.3 grams. This method can effectively solve the problem that the quantitative dispensing method of the screw rotating at equal intervals in the prior art has low accuracy and is not convenient to control the weight of powder dispensed each time.

[0028] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
