Currently, intelligent packaging machines on the market can automatically weigh the materials before packaging, which improves work efficiency.

[0003] The patent name disclosed in the prior art with application number "CN201811654668.2" is "A quantitative packaging scale and weighing method", which discloses that the upper and lower volume adjustment quantitative discharge bin includes an upper cylinder with a feed baffle on the top, the bottom of the upper cylinder is movably sleeved in the lower cylinder, the bottom of the lower cylinder is provided with a discharge baffle, the interior of the upper cylinder and the lower cylinder are connected, and the outer side of the lower cylinder is connected to the first retractable power device; the top of the feed baffle is connected to the bottom of the bin, and the bottom of the discharge baffle is relatively A weighing bucket is provided at the corresponding position. The upper and lower volume adjustment quantitative discharge bins are mainly in the form of an upper cylinder and a lower cylinder set. The upper cylinder is fixed and the lower cylinder can move up and down to achieve the purpose of changing the volume of the upper and lower volume adjustment quantitative discharge bins. The feed baffle is used to allow the material in the bin to smoothly enter the upper and lower volume adjustment quantitative discharge bins. The discharge baffle is used to allow the material in the upper and lower volume adjustment quantitative discharge bins to smoothly enter the weighing bucket. The upper and lower volume adjustment quantitative discharge bins are used to ensure the volume of the material to achieve the purpose of ensuring the weight of the material.

[0004] The patent name disclosed in the prior art with application number "CN201611231099.1" is "a weighing packaging machine", which discloses that a loading hopper is installed on the silo, the silo is connected to the fuselage through a material guide cylinder, a hook is installed on the fuselage, a packaging bag is hung on the hook, a roller conveyor is installed below the packaging bag, a pressure sensor is installed below the fuselage, and the pressure sensor is connected to the load-bearing mechanism. In order to facilitate loading, a loading conveyor belt is installed above the loading hopper. In order to control the unloading speed of the material in the silo, a unloading valve is installed in the silo. There are two hooks, which can be fixed to the fuselage by bolts. In order to facilitate the sealing of the packaging bag, a bag pressing mechanism is installed on the material guide cylinder.

[0053] A relative regulating component is installed inside the support frame 1, and the upper control board 8 and the lower control board 9 are controlled to move synchronously toward each other by the relative regulating component. A moving column 10 is installed through the middle of the support bottom plate 2, and three groups of moving frames 11 are symmetrically installed on the outside of the moving column 10, each group is provided with two, and a group of weighing buckets 5 are arranged on the inner side of a group of moving frames 11. The lower end of the weighing bucket 5 is arranged in a funnel shape, and two first sliders 51 are symmetrically installed on the outer side of the weighing bucket 5. The outer side of the first slider 51 is slidably connected to the groove on the inner side of the moving frame 11, and a return spring 111 is installed in the groove on the inner side of the moving frame 11. One end of the return spring 111 is connected to the first slider 51, and the inner wall of the weighing bucket 5 is slotted and slidably connected with a "T" shape. The support rod 12 has a shaped structure, and the left and right ends of the support rod 12 are connected to the connecting spring 121 in the groove of the inner wall of the weighing bucket 5. The lower end of the support rod 12 is installed with a blocking block 122 with a conical structure on the top. The bottom of the blocking block 122 is concave-convexly matched with the groove on the bottom surface of the weighing bucket 5. The diameter of the bottom of the blocking block 122 is smaller than the diameter of the discharge port 201. The relative control component includes a rotating rod 14 installed inside the support frame 1, and a first control plate 13 is installed on the outer side of the rotating rod 14. The first control plate 13 has first control grooves 131 symmetrically opened on the upper and lower inner parts. The front sides of the upper control plate 8 and the lower control plate 9 are installed with convex rods 16, and the front ends of the convex rods 16 are inserted into the first control grooves 131.

[0054] First, the entire automatic weighing intelligent packaging machine is moved into the working area. At this time, the overall weight of the weighing bucket 5 directly above is measured by the weighing mechanism 18, and then the external material can be transported to the temporary storage box 3 through the external feeding mechanism. At this time, the valve below the temporary storage box 3 is opened, and the material in the temporary storage box 3 will enter the unloading connecting hose 4, and then the material falls into the weighing bucket 5 directly below through the unloading connecting hose 4. At the same time, the servo motor in the supporting frame 1 is started, and the servo motor drives the rotating rod 14 to rotate clockwise and counterclockwise at a certain angle, and then the rotating rod 14 rotates to drive the first regulating plate 13 to rotate and swing back and forth. At this time, the first regulating plate 13 cooperates with the first regulating slots 131 on the upper and lower sides to pull the upper and lower convex rods 16 to move back and forth to the left and right in opposite directions, so that the two convex rods 16 drive the upper control plate 8 and the lower control plate 9 to move back and forth to the left and right in opposite directions.

[0055] The detailed steps are as follows: when the upper convex rod 16 drives the upper control plate 8 to slide to the left in the support frame 1, the upper control plate 8 is connected with the second slider 191 and the regulating vertical rod 192 through the support frame 15, so that the upper control plate 8 pulls the mounting plate 19 to the left. At the same time, when the lower convex rod 16 drives the lower control plate 9 to slide to the right in the support frame 1, the lower control plate 9 will apply a rightward thrust to one of the weighing buckets 5. At this time, the first slider 51 on the outer side of the weighing bucket 5 slides in the groove on the inner side of the moving frame 11, and at the same time squeezes and accumulates force on the return spring 111. When the lower control plate 9 moves to the left, the return spring 111 is used to press the return spring 111. The stored force of 1 will automatically drive the weighing bucket 5 to move in the opposite direction and reset. Such repeated operations will make the mounting plate 19 and the weighing bucket 5 move toward each other synchronously, so it is convenient to change the position of the mounting plate 19, so that the mounting plate 19 drives the unloading connecting hose 4 to evenly drop the material into the weighing bucket 5. At the same time, through the left and right reciprocating movement of the weighing bucket 5, it is convenient for the weighing bucket 5 to automatically shake the material inside, thereby further making the material evenly distributed in the weighing bucket 5, without the need for manual shaking by the staff, and will not affect the carrying capacity of the weighing bucket 5. The operation is convenient, it is convenient to carry out automatic weighing, and also improves the packaging efficiency of the entire intelligent packaging machine.

[0056] After unloading for a period of time, the rotation of the rotating rod 14 is stopped. At this time, the weighing mechanism 18 automatically weighs the weight of the weighing bucket 5 above. When the weighed value is subtracted from the overall weight value of the weighing bucket 5, the value obtained is equal to a specific value. At this time, the valve is closed, and the unloading of the material in the unloading connecting hose 4 is stopped. Then, the motor in the supporting bottom plate 2 is started to drive the moving column 10 to rotate. When the moving column 10 rotates, it drives the three groups of weighing buckets 5 to rotate 120° through the three groups of moving frames 11. At this time, the weighing bucket 5 filled with materials rotates to the lower Just above the material port 201, the support rod 12 and the blocking block 122 are automatically driven downward by the stored force of the connecting spring 121. At this time, the blocking block 122 penetrates the bottom surface of the weighing bucket 5 and the material port 201 and moves downward. At this time, the material in the weighing bucket 5 falls through the material port 201 into the packaging bag pre-opened and placed on the conveying mechanism 6 just below, and then the packaging bag containing the material is transported to the right through the conveying mechanism 6, and then sealed by the sealing mechanism 7. Since this part is a prior art, it will not be introduced in detail here.

[0057] At the same time, another empty weighing bucket 5 rotates to the top of the weighing mechanism 18 to continue the material receiving and weighing operation. When the weighing bucket 5 needs to be rotated, it is necessary to manually move the blocking block 122 below the discharge port 201 upward so that the blocking block 122 enters the weighing bucket 5. At this time, the weighing bucket 5 is driven to rotate by the moving column 10. This process is repeated so that the three groups of weighing buckets 5 can continuously and automatically weigh the materials, thereby improving the efficiency of weighing and the efficiency of subsequent packaging work.

[0058] Embodiment 2: The intelligent packaging machine with automatic weighing in this embodiment can further evenly drop the materials into a certain area, further improving the efficiency of automatic weighing and packaging. Figure 8-Figure 11 As shown, the upper surface of the upper control panel 8 is provided with a second regulating plate 17, and a second regulating through groove 172 is provided inside the second regulating plate 17. A sliding block 171 is installed at the lower left side of the second regulating plate 17, and the lower part of the sliding block 171 is slidably connected with the groove provided on the upper surface of the upper control panel 8. The right side of the support frame 15 and the upper and lower side surfaces are provided with sliding through grooves, and the second slider 191 and the regulating vertical rod 192 are both slidably connected with the support frame 15. The right side of the second regulating plate 17 is connected to the regulating vertical rod 192 is connected to the upper part of the upper control plate 8, a self-rotating rod 20 is installed on the upper surface of the upper control plate 8, a push rod 23 with a mirror image "L" shape structure is installed on the upper end of the self-rotating rod 20, and a rotation control mechanism is installed on the lower end of the self-rotating rod 20. The upper end of the push rod 23 is inserted into the second regulating groove 172, and the second regulating plate 17 forms a front and rear reciprocating rotation with the upper control plate 8 through the push rod 23. The rotation control mechanism includes a connecting rope 22 wound around the lower end of the self-rotating rod 20, and the lower end of the self-rotating rod 20 is penetrated. On the lower surface of the upper control plate 8, the other end of the connecting rope 22 is connected to the right side surface of the support frame body 1; a vortex spring 21 is nested and connected to the outer side of the self-rotating rod 20, and one end of the vortex spring 21 is connected to the bottom surface of the upper control plate 8. On the basis of Example 1, when the upper control plate 8 moves to the left, the connecting rope 22 is not pulled at this time, and the self-rotating rod 20 can be automatically driven to rotate by the stored force of the vortex spring 21. When the self-rotating rod 20 rotates, it drives the pushing rod 23 to rotate. At this time, the upper end of the pushing rod 23 moves in the second regulating through groove 172, thereby pushing the second regulating plate 17 to move back and forth. At this time, the sliding block 171 on the left bottom surface of the second regulating plate 17 slides stably in the groove on the upper surface of the upper control plate 8, and then the second regulating plate 17 drives the regulating vertical rod 192 and the mounting plate 19 to move back and forth. At this time, the regulating vertical rod 192 and the second sliding block 191 slide in the support frame 15, thereby ensuring that the mounting plate 19 and the blanking connecting hose 4 can stably move back and forth.

[0059] When the upper control panel 8 moves to the right, the connecting rope 22 is pulled, and the connecting rope 22 can automatically drive the self-rotating rod 20 to rotate. When the self-rotating rod 20 rotates, it drives the pushing rod 23 to rotate, as shown above. Similarly, the second regulating plate 17 drives the mounting plate 19 and the unloading connecting hose 4 to move back and forth. Then it can be known that while the upper control panel 8 drives the mounting plate 19 and the unloading connecting hose 4 to move back and forth, the regulating vertical rod 192 drives the mounting plate 19 and the unloading connecting hose 4 to move back and forth, thereby making the mounting plate 19 and the unloading connecting hose 4 move in a "W" shaped trajectory, thereby further making the unloading connecting hose 4 drop the material to various positions in the weighing bucket 5, and later cooperate with the left and right shaking of the weighing bucket 5, so that the uniformity of the material in the weighing bucket 5 can be further improved, without the need for manual shaking by the staff, the operation is convenient, and the carrying capacity of the weighing bucket 5 will not be affected, which is convenient for good automatic weighing, and also improves the packaging efficiency of the entire intelligent packaging machine and saves energy.

[0060] Embodiment 3: The intelligent packaging machine with automatic weighing in this embodiment discloses a rotation control mechanism of another structure. On the basis of embodiment 2, the rotation control mechanism is a motor, which includes a motor installed inside the upper control plate 8. The output end of the motor is connected to the lower end of the self-rotating rod 20. By installing the motor in the upper control plate 8 and starting the motor, the motor drives the self-rotating rod 20 to rotate, and the self-rotating rod 20 drives the push rod 23 to rotate. Then the upper end of the push rod 23 moves in the second regulating groove 172, thereby making the second regulating plate 17 move back and forth. At this time, the second regulating plate 17 drives the mounting plate 19 and the unloading connecting hose 4 to move back and forth. The operation is convenient, thereby completing a series of tasks.
