Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tobacco conveying, in particular to a conveying box lifting device based on a chain conveyor. Background Art
[0002] In the leaf threshing and redrying process, chain conveyors are often used to transport raw tobacco boxes. After the raw tobacco is unloaded and packed, it is transported to the leaf threshing and redrying process in batches of 300kg / box through the chain conveyor unit of the automated logistics system for the next step of raw tobacco processing. The raw tobacco boxes are driven by the chain conveyor and transported to the position in front of the vacuum rehumidification machine to wait for processing. Each group of 6 raw tobacco boxes / time enters the processing rehumidification machine for processing. The raw tobacco vacuum rehumidification process is mainly composed of chain conveyors, raw tobacco boxes and vacuum rehumidification machines.
[0003] In actual use, due to vibration during transportation and 90° turning of the raw cigarette box, the parking position of the raw cigarette box is deviated. It is difficult to ensure that the nylon pad at the bottom of the raw cigarette box and the chain of the chain conveyor coincide with the axis, causing the raw cigarette box to deviate on the chain of the chain conveyor, which can easily cause equipment failures such as the box tilting and knocking down the detection photoelectric tube, affecting the stability and safety of the transportation system. In response to the movement deviation of the raw cigarette box during the chain conveyor transportation and the different axis movement of the raw cigarette box, some companies use the manual crowbar correction method to correct it. However, since each raw cigarette box weighs 300kg and each box weighs 600kg after being filled with materials, it is difficult to correct the movement trajectory of the raw cigarette box manually, and safety is difficult to ensure during the correction process. The crowbar correction method may also cause irreparable damage to the raw cigarette box. Utility Model Content

Exemplarily, the rotating shaft 300 can adopt a crankshaft, so as to increase the movement stroke of the support seat 100 and the connecting seat 200, and increase the lifting height of the original cigarette box. The rotating shaft 300 is connected to the inner ring of the first eccentric bearing 110 and the inner ring of the second eccentric bearing 210 by interference fit.
[0037] Optionally, the driving member is a motor, and the support frame 400 is provided with an in-place detection switch, the circuit control loop of the in-place detection switch is electrically connected to the motor, and the in-place detection switch detects that the original cigarette box is transported to the top of the support frame 400, and the circuit control loop of the in-place detection switch controls the motor to drive the rotating shaft 300 to rotate, and the rotating shaft 300 drives the inner ring of the first eccentric bearing 110 and the inner ring of the second eccentric bearing 210 to rotate, and the first eccentric bearing 110 generates a downward pressure on the support seat 100, which is transmitted to the chain conveyor.

[0041] The utility model provides a conveying box lifting device based on a chain conveyor, which solves the problems of difficulty in manual deviation correction of a raw cigarette box conveyed by a chain conveyor 10 and lack of bottom support force.
[0042] During the rotation of the rotating shaft 300 driven by the motor, the inner ring of the first eccentric bearing 110 and the inner ring of the second eccentric bearing 210 are driven to rotate to generate an offset stroke, and a reverse thrust is applied to the support seat 100 and the connecting seat 200 to generate an upward lifting force to lift the support frame 400. The support frame 400 lifts the raw cigarette box through the roller shaft 410, so that the raw cigarette box is separated from the chain support of the chain conveyor 10. The roller surface of the roller shaft 410 ensures that the raw cigarette box can be easily pushed after being lifted.
[0043] The original cigarette box triggers the arrival detection switch to send a cigarette box arrival signal to the circuit control circuit, and the circuit control circuit controls the motor to drive the rotating shaft 300 to rotate, and the rotating shaft 300 drives the inner ring of the first eccentric bearing 110 and the inner ring of the second eccentric bearing 210 to rotate. The first eccentric bearing 110 generates a downward pressure on the support seat 100, which is transmitted to the lower guard plate 11 of the chain conveyor 10. The lower guard plate 11 generates a reverse lifting force to act on the connecting seat 200, and at the same time, the second eccentric bearing 210 generates a downward pressure on the connecting seat 200. The upward pressure is transmitted to the support frame 400, and the support frame 400 is lifted under the joint action of the first eccentric bearing 110 and the second eccentric bearing 210, and the support frame 400 drives the roller shaft 410 to lift, so that the support frame 400 lifts the raw cigarette box through the roller shaft 410 to separate it from the chain of the chain conveyor 10, and completes the lifting of the raw cigarette box. At this time, the raw cigarette box is supported by force, and with the roller surface of the roller shaft 410, the raw cigarette box can be offset by giving artificial thrust on the side of the raw cigarette box. It can also reduce the problems of the raw cigarette box rubbing against the edge and skewing when moving on the chain of the chain conveyor 10, and lifting the raw cigarette box can save the efficiency of manual correction and adjustment.
