Description

Technical Field

[0001] The utility model relates to a weight placement device for adjusting weights, and in particular to a weight placement device for quickly adjusting the weighing accuracy of a storage barrel in a feeder device, which belongs to the field of tobacco processing equipment. Background Art

[0002] Generally speaking, in current tobacco enterprises, the storage barrels in the feeder equipment are relatively high, and the height is mostly above 1.9 meters. In addition, since the three sets of weighing sensors of the storage barrel are located on the legs below the storage barrel, and since the legs and the storage barrel are both cylindrical, it is impossible to place the weights for weighing and adjusting the weights. The weights for weighing and adjusting the weights can only be placed on the upper cover panel of the storage barrel. Since the upper cover panel of the storage barrel is arranged with exhaust pipes, cleaning water pipes, inlet and outlet pipes for liquid, and liquid stirring transmission, the placement and number of weights are limited, which affects the weighing and adjusting accuracy of the storage barrel. Since the weights are placed at a height of more than 1.9 meters, the adjustment personnel need to use a mobile ladder to assist in climbing to place the adjustment weights. Each weight weighs 20KG, and the weights are put on and taken off. Placing and removing weights is a high-altitude operation, which not only consumes a lot of manpower and has the safety hazard of personnel falling, but also the weighing and adjusting accuracy cannot achieve the ideal effect. Considering the existence of the above problems, it is urgent to provide an effective solution.

[0003] After searching, it is found that the Chinese utility model patent with announcement number CN207248337U currently discloses an automatic auxiliary calibration device for a lithium battery feeding system, in which a lifting mechanism is set on one side of the storage tank and weights are placed on the lifting mechanism.

[0070] Check the stacking stability of weight 6

[0071] Qualitative.

[0072] like Figure 3 As shown, the clamping body 1 is an arc-shaped plate-like body, one end of which is open, and the first fixing plate 1a and the second fixing plate 1b are respectively connected at both ends of the opening; wherein:

[0073] One side of the first fixing plate 1a is a hexagonal screw hole, and the other side is a circular screw hole; both sides of the second fixing plate 1b are circular screw holes.

[0074] Specifically, Figure 3 As shown, the hexagonal holes and the circular screw holes on the first fixing plate 1a are connected; the circular screw holes on both sides of the second fixing plate 1b are connected.

[0075] In the present invention, the holes on the first fixing plate 1a and the second fixing plate 1b correspond to and match the shapes of the two ends of the pin screw 5a.

[0079] The fastening component 5c is screwed and installed on the end of the locking member 5a to play a role of limiting and fastening.

[0080] Specifically, Figure 3 As shown, the locking member 5a is a pin screw or a common bolt;

[0081] The limiting member 5b is a spring, and the spring is connected to the locking member 5a between the first fixing plate 1a and the second fixing plate 1b;

[0082] The fastening component 5c is a common nut.

[0083] In the present invention, the locking member 5a is a pin screw, which has good penetration and fixation and can be used under greater force and heavy load;

[0084] When the locking member 5a is screwed into the screw hole, the spring will be compressed, generating a pre-tightening force, which helps to keep the screw in place and prevent it from loosening by itself;

When the measurement accuracy error is ≤0.5% and the half-scale calibration is completed, all weights on the weight support plate 2 are removed, and the weighing device 8 is calibrated for empty-scale measurement accuracy. After all calibrations are completed, each set of weighing precision quick adjustment weight placement devices is removed, and the weighing adjustment is completed. The utility model solves the problems of difficulty in weighing and adjusting the storage barrel and risk of high-altitude placement in existing feeding machine equipment, and through the design of the clamping body, the weight support plate and the fastening assembly, the adjustment weights can be stably placed on the storage barrel legs without climbing, which effectively improves work safety. The detachable design is convenient for installation and adjustment, and the strong magnet in the weight support plate increases the stability of weight stacking. The utility model is not only suitable for high storage barrels, but also can adapt to legs of different sizes, and the number of weights can be adjusted according to needs to meet different precision adjustment requirements. The utility model has the advantages of convenient operation and strong adaptability.

[0089] Finally, as time goes by, after use, the operator dismantles the utility model as needed. When dismantling, the operator only needs to loosen the limit piece 5c, and then take out the locking piece 5a, and then the clamping body 1 of the utility model can be separated from the support leg 7.
