Description

Technical Field

[0001] The utility model relates to the technical field of radial winding packaging and weighing of cylindrical objects, in particular to a weighing turntable of a radial winding packaging machine. Background Art

[0002] In the radial wrapping packaging process of cylindrical objects such as paper rolls, when weighing the goods, the goods need to be hoisted onto the scale for weighing, which will reduce work efficiency. In order to improve work efficiency, a weighing module can be added under the radial wrapping packaging machine.

[0003] Most weighing equipment that uses weighing modules have two ways of selecting and installing weighing modules: one way is to use 4 groups of dynamic weighing modules. The weighing sensor of the dynamic weighing module can automatically adjust the center, and its built-in limit device is mostly a top limit. In order to ensure the measurement accuracy, a certain limit gap must be left. If the radial wrapping packaging machine adopts this method, the turntable will shake when it rotates and starts and stops, which seriously affects the quality of the wrapping packaging; the other way is to use a combination of dynamic weighing module + static weighing module. The static weighing module cannot achieve automatic adjustment, and its horizontal limit is completely realized by the hard limit between the static weighing module weighing sensor and the sensor pressure head. If the radial wrapping packaging machine adopts this method, the inertial force generated by the frequent start and stop of the turntable will cause the state between the weighing sensor and the sensor pressure head to change, so that there is an unstable component force in the vertical direction between the weighing sensor and the pressure head, thereby affecting the measurement accuracy. In severe cases, the sensor pressure head will be deformed or broken, causing equipment damage and safety hazards. Utility Model Content

[0004] In order to overcome the defects in the prior art that the turntable will shake, thereby affecting the quality of the wrapping package, and the inertial force generated by the frequent start and stop of the turntable will cause the state between the weighing sensor and the sensor pressure head to change, thereby affecting the measurement accuracy, the utility model provides a weighing turntable for a radial wrapping packaging machine.

[0006] As a further improvement of the utility model, the weighing sensor assembly includes an upper pad and a lower pad, a weighing sensor is provided at the lower portion of the upper pad, and the bottom of one end of the weighing sensor is connected to the lower pad via a sensor pressure head.

[0007] As a further improvement of the utility model, the adjustment seat includes an upper seat and a base, the upper seat is installed in the base, the upper surface of the upper seat is threadedly connected with four height adjustment bolts, and each side of the base is threadedly connected with a horizontal limit bolt.

[0008] As a further improvement of the utility model, both the height adjustment bolt and the horizontal limit bolt are provided with fastening nuts that can be tightened.

[0009] As a further improvement of the utility model, the pull rod limiting device includes a pull rod base and a pull rod side seat, and the pull rod base and the pull rod side seat are hingedly connected through the pull rod.

[0010] As a further improvement of the present invention, the pull rod base and the pull rod side seat are respectively hinged to the left-hand rod end joint bearing and the right-hand rod end joint bearing through a pin shaft, and the two ends of the pull rod are respectively connected to the left-hand rod end joint bearing and the right-hand rod end joint bearing, and the two ends of the pull rod are respectively provided with a left-hand nut and a right-hand nut for tightening the left-hand rod end joint bearing and the right-hand rod end joint bearing.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] (1) The tie rod limit device adopts a horizontal tie rod limit device. The two ends of the tie rod are respectively hinged with the rod end joint bearing to ensure that the tie rod and the equipment are installed horizontally. During the use of the equipment, no vertical force that affects the measurement accuracy will be generated. It can effectively avoid the displacement and shaking caused by the rotation and start and stop of the turntable, ensuring the smooth operation of the equipment and the accuracy of the measurement.

[0013] (2) The weighing sensor assembly is installed on the adjustment seat. The height and levelness of the weighing sensor installation position can be adjusted by adjusting the height adjustment bolt of the adjustment seat. At the same time, the base of the adjustment seat is in contact with the base plate. The contact surface is small and the levelness requirement of the base plate is low, which effectively reduces the cost of equipment processing and foundation construction.
