Detailed Description
The utility model will be further described with reference to the accompanying drawings and specific examples.
Reference numerals in the drawings of the specification include: tensioning screw 1, gasket 2, spring 3, curb plate 4, tensioning board 5, nut 6, self-control nut 7, slider bearing frame 8, slider bearing rail 9, tensioning sprocket 10, chain 11, sprocket 12.
Example 1:
1-2, the self-tensioning device for the narrow-band sorter comprises a mounting frame, a tensioning screw 1, a nut 6, a spring 3 and a sliding block bearing seat 8, wherein the mounting frame is rectangular, the mounting frame is fixed on a rack and comprises an upper side plate 4, a lower side plate 4, a left baffle and a right baffle, sliding block bearing guide rails 9 which are oppositely arranged are fixed on the inner side walls of the right parts of the two side plates 4, sliding grooves matched with the sliding block bearing guide rails 9 are correspondingly arranged at the upper end and the lower end of the sliding block bearing seat 8, the sliding grooves are in sliding connection with the sliding block bearing guide rails 9, so that the sliding block bearing seat 8 is in sliding connection with the center of the mounting frame, and a through hole is formed in the center of the sliding block bearing seat 8 and used for fixedly mounting the sliding block bearing seat 8 on a mounting shaft of a tensioning chain wheel 10; the tensioning screw 1 is arranged along the horizontal direction, the right end of the tensioning screw 1 is connected to the left end of the sliding block bearing seat 8 through self-made nuts 7 in a threaded mode, through holes with the size larger than the diameter of the tensioning screw 1 are formed in the left baffle of the installation frame, the left end of the tensioning screw 1 penetrates through the through holes, the nuts 6 are connected to the tensioning screw 1 in a threaded mode, the springs 3 are sleeved on the tensioning screw 1, the right ends of the springs 3 abut against the nuts 6, and the left ends of the springs 3 abut against the left baffle of the installation frame. In the embodiment, a gasket 2 is sleeved on the tensioning screw 1, and the gasket 2 is positioned between a spring 3 and a left baffle plate of the mounting frame; the tensioning screw 1 is sleeved with a tensioning plate 5, the tensioning plate 5 is located between the spring 3 and the nut 6, the cross section of the tensioning plate 5 is L-shaped, a limiting plate for limiting the limiting position of the tensioning plate 5 to move leftwards is fixed on a left baffle plate of the installation frame, the limiting plate is parallel to the axis of the tensioning screw 1, and the number of the limiting plates is 2 and corresponds to the upper end and the lower end of the tensioning plate 5 respectively.
