[0019] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are only used to explain the present application and cannot be interpreted as a limitation on the present application. Figures 1-4 As shown in the drawings, a weighing device for a cigarette packaging machine, comprising a numerical control rotating shaft 1, the numerical control rotating shaft 1 is installed on a support platform, a weighing platform 2 is fixedly arranged on the outer wall of the middle part of the numerical control rotating shaft 1, a plurality of receiving holes 3 are formed in the weighing platform 2, a weighing disc 4 is rotatably connected to the inner side wall below each receiving hole 3 through a reset rotating shaft, a support block 5 is installed on the numerical control rotating shaft 1, the support block 5 is located below the weighing platform 2, a first docking hole 6 is formed in the support block 5, a lower conveying platform 8 is arranged on the support platform, one end of the lower conveying platform 8 is located below the support block 5, the first docking hole 6 is aligned with the lower conveying platform 8, an upper conveying platform 7 is arranged on the upper side of the weighing platform 2, and a leakage hole 9 is formed in the upper conveying platform 7.
[0020] It should be noted that the numerical control rotating shaft 1 and the reset rotating shaft are commercially available products and can be directly purchased, and the support platform and the reset rotating shaft are not shown in the drawings. The upper conveying platform 7 is connected to the cigarette packaging machine in the prior art, the numerical control rotating shaft 1 is used to drive the weighing platform 2 to rotate, so that the cigarette box in the upper conveying platform 7 can fall into the receiving hole 3 on the weighing platform 2, and the cigarette box in the receiving hole 3 is weighed by the weighing disc 4. If the weight of the weighed cigarette box meets the standard, the weighing disc 4 flips the cigarette box to fall into the first docking hole 6 on the lower conveying platform 8, and then the cigarette box is conveyed to the next station by the lower conveying platform 8.
[0021] In a specific embodiment, the bottom end of the leakage hole 9 is fixedly connected with a guide plate 10, and the guide plate 10 is inclined. Through the guiding effect of the guide plate 10, the falling posture of the cigarette box in the upper conveying platform 7 during the process of falling from the leakage hole 9 into the receiving hole 3 is effectively avoided, so that the cigarette box is not stuck in the receiving hole 3 and cannot fall into the lower conveying platform 8.
[0022] A connecting ring 11 is rotatably connected to the outer wall of the upper end of the numerical control rotating shaft 1, and two limiting rods 12 are fixedly connected between the connecting ring 11 and the upper conveying platform 7. Through the limiting effect of the limiting rods 12, the position of the upper conveying platform 7 cannot be changed, so that the cigarette box in the upper conveying platform 7 can be accurately placed into the receiving hole 3 from the leakage hole 9.
[0023] The numerical control rotating shaft 1 is rotatably connected with the supporting block 5 through the bearing 13. The deflection of the supporting block 5 caused by the friction force during the long-time rotation of the numerical control rotating shaft 1 is effectively avoided, so that the first docking hole 6 cannot be docked with the lower conveying platform 8.
[0024] In the embodiment, the weighing platform 2 is in a cylindrical structure, a through hole for installing the numerical control rotating shaft 1 is arranged at the center of the weighing platform 2, the supporting block 5 is a circular supporting block, and the outer diameter of the supporting block 5 is equal to the outer diameter of the weighing platform 2. The supporting block 5 is fixedly connected with the top of the lower conveying platform 8.
[0025] The bottom end of the numerical control rotating shaft 1 is fixedly connected with the damping block 14, and the damping block 14 is fixedly connected to the supporting platform. Through the damping effect of the damping block 14, the vibration generated during the rotation of the numerical control rotating shaft 1 is effectively reduced, so that the vibration is not transmitted to the upper conveying platform 7, and the cigarette boxes conveyed in the upper conveying platform 7 cannot be accurately dropped into the receiving hole 3.
[0026] The second docking hole 15 is arranged on the supporting block 5, and the second docking hole 15 is symmetrically distributed on both sides of the numerical control rotating shaft 1 with the first docking hole 6. The leakage hole 9 is located at the upper middle part of the second docking hole 15 and the first docking hole 6. Specifically, the perpendicular projection of the leakage hole 9 on the supporting block 5 is equal to the distance from the second docking hole 15 and the first docking hole 6. Assuming that the perpendicular projection of the leakage hole 9 on the supporting block 5 is at the 12 o'clock position of the supporting block 5, the first docking hole 6 is at the 3 o'clock position, and the second docking hole 15 is at the 9 o'clock position.
[0027] The supporting platform is further provided with a recycling platform 16, one end of the recycling platform 16 is located below the supporting block 5, a magnetic block is arranged inside the recycling platform 16 close to the second docking hole 15, and the outer end wall of the weighing disc 4 is coated with magnetic paint.
[0028] In the actual weighing detection process, due to the limited space of the cigarette box, it is often found that the actual weight of the cigarette box is less likely to be larger than the expected value. When the production line is out of order, the actual weight of the cigarette box is generally smaller than the expected value. Based on the above premise, the operator can set the gravity that can be borne by the reset rotating shaft on the weighing disc 4 to the expected value of the cigarette box. At this time, when the weight of the cigarette box borne in the receiving hole 3 is less than the expected value, the weighing disc 4 will not be turned over, and the cigarette box cannot fall into the lower conveying platform 8, but through the rotation of the numerical control rotating shaft 1, the cigarette box with low weight in the receiving hole 3 is carried to the second docking hole 15 on the supporting block 5. At this time, the weighing disc 4 at the second docking hole 15 is attracted downward by the magnet installed in the recycling platform 16 below the second docking hole 15, and the cigarette box borne thereon falls into the recycling platform 16 through the second docking hole 15. Through the above-mentioned way, the cigarette box with unqualified weight is sorted out, and the use convenience of the device is increased.
[0029] The working principle of the utility model is: the operator firstly assembles the device and checks whether each component is in good operation, and then the operator adjusts the rotating speed of the numerical control rotating shaft 1 through the control terminal, the control terminal is prior art, for example, PLC programmable controller, the control terminal matches the transport speed of the cigarette box in the upper transport platform 7 with the numerical control rotating shaft 1, the cigarette packaging machine sends the cigarette box to the upper transport platform 7, the cigarette box transported on the upper transport platform 7 finally falls in the leakage hole 9 and enters the receiving hole 3, and the cigarette box is weighed through the weighing disc 4 installed in the receiving hole 3, and the data is transmitted back to the control terminal, and when the receiving hole 3 with the cigarette box moves to the first docking hole 6 drilled on the supporting block 5 synchronously with the rotation of the numerical control rotating shaft 1, the weighing disc 4 is turned over and opened under the action of gravity because the weighing disc 4 loses the support of the supporting block 5, the cigarette box falls into the lower transport platform 8 and is transported to the next station, and after the weighing disc 4 loses the gravity of the cigarette box, the weighing disc 4 immediately restores to the original horizontal state through the reset effect of the reset shaft on the weighing disc 4, waiting for the next weighing operation; if there is a lack of support in the cigarette box, the weight of the cigarette box is less than the expected value, and the weighing disc 4 cannot be turned over by the self weight of the cigarette box,
[0030] The cigarette box with low weight in the receiving hole 3 is carried to the second docking hole 15 on the supporting block 5 through the rotation of the numerical control rotating shaft 1, at this time, the weighing disc 4 located at the second docking hole 15 is attracted downward and opened by the magnet installed on the recovery platform 16 below the second docking hole 15, and the cigarette box carried thereon falls into the recovery platform 16 through the second docking hole 15, and the cigarette box with unqualified weight is sorted out through the above-mentioned mode, the comprehensive weighing of the cigarette box is realized under the premise that the production line production speed is not greatly reduced, the possibility of omission is reduced, so that the problems existing in the production line can be found in time, and the loss is reduced.
[0031] The above embodiment according to the drawings details the structure, features and effect of the utility model, the above-mentioned is only the preferred embodiment of the utility model, but the utility model is not limited to the drawings shown in the implementation range, any change or modification made according to the concept of the utility model, or the equivalent embodiment of equivalent change, still within the protection scope of the utility model as long as it does not exceed the spirit covered by the specification and drawings.
