Description

TECHNICAL FIELD

[0001] The utility model relates to electric bag hanging device technical field, specifically a kind of electric bag hanging device of upper weighing ton bag packing scale. BACKGROUND

[0002] The upper weighing ton bag packing scale mainly relies on the weighing sensor to measure the weight of the material. When the material is poured into the weighing hopper of the scale, the sensor will capture the weight change of the material in the hopper and transmit these data to the control system. The control system accurately measures the material according to the preset packaging weight and stops adding material when the target weight is reached. Subsequently, the material in the weighing hopper is poured into the ton bag or other container through a specific mechanical structure, such as a pneumatic or electric device.

[0003] During the use of the above structure, when it is necessary to hang the bag body under the weighing body, the worker usually needs to manually complete the bag hanging operation. Specifically, the worker holds the bag body and connects its four corners with the four hooks of the device in turn. Since the bag body is usually large, the worker needs to change position and posture during the bag hanging process to facilitate the hanging of all connection points. The operation is relatively cumbersome. Some devices have a bag hanging structure that can be manually rotated to facilitate the bag hanging work. However, the manual operation mode requires the worker to operate the rotating structure with one hand, which also affects the bag hanging efficiency. Therefore, the electric bag hanging device of the upper weighing ton bag packing scale is proposed to solve the above problems. SUMMARY

[0004] The technical problem to be solved by the utility model is to provide an electric bag hanging device of an upper weighing ton bag packing scale. The electric bag hanging device can drive the bag hanging frame to rotate through the rotary connection mechanism, so that the hooks far from the current position of the worker are rotated to the front position of the worker, facilitating the bag hanging work. The automatic rotating structure can free the worker's hands and improve the bag hanging efficiency. In addition, to avoid excessive rotation of the bag hanging frame and offset the optimal position of the unbagged hook, the device is equipped with a cooperating motion brake mechanism, a limiting mechanism, and a stop mechanism, which can constrain the rotation stroke of the bag hanging frame and fix its position when it rotates to the maximum stroke, so that the rotating hook can be in a position convenient for operation and fixed, ensuring efficient bag hanging work. The technical problems of the prior art, such as the need for workers to frequently change position and posture during bag hanging due to the different positions of the four hooks, the cumbersome operation, and the manual rotating bag hanging structure that affects the bag hanging efficiency to some extent, are solved.

[0010] In a possible implementation, the bag hanging frame comprises a ring frame fixedly connected to the transmission gear supporting shaft, and a cross-shaped hanging frame is fixedly arranged on the side surface of the ring frame.

[0012] In a possible implementation, the in-position stopping mechanism comprises a first mounting plate fixedly arranged on the bag hanging frame, and a proximity switch is arranged on the first mounting plate to detect the bending brake pad; when the bag hanging frame rotates and the bending brake pad on the bag hanging frame moves close to the proximity switch, the proximity switch can identify and provide a necessary structure basis for the operation of the stopping mechanism.

[0013] In a possible implementation, a cantilever frame is arranged on the first mounting plate, and a pneumatic brake cylinder is fixedly arranged at the bottom of the cantilever frame; a stopping groove corresponding to the size of the bending brake pad is arranged on the pneumatic brake cylinder; when the bending brake pad moves through the proximity switch, an identification signal is generated; at this time, the pneumatic brake cylinder works, clamps the bending brake pad in the stopping groove, and prevents the bag hanging frame from continuing to rotate, thereby facilitating the worker to hang the bag.
