An idler roller adjustment device for a short material sander

Abstract

The invention discloses an idle roller adjusting device for a short material sanding machine. The idle roller adjusting device comprises two support base plates (1), and each pressing mechanism comprises idle rolling supports (4), springs (5), rolling shaft sleeves (6), an idle roller (7), double-headed studs A (8) and double-headed studs B (9), wherein a limiting nut (11) is connected to the upper threaded end of each double-headed stud A (8), the upper threaded end of each double-headed stud B (9) upwards penetrates through the corresponding extending part to be connected with the corresponding rolling shaft sleeve (6), an adjusting nut (12) is connected to the lower threaded end of each double-headed stud B (9), each adjusting nut (12) is located below the corresponding extending part, each spring (5) sleeves on the corresponding double-headed stud B (9), the top end of each spring (5) is fixedly connected to the corresponding extending part, and the bottom end of each spring (5) abuts against the corresponding adjusting nut (12). The idle roller adjusting device for the short material sanding machine has the beneficial effects that pre-tightening force of the idle roller can be adjusted, the up and down height position of the idle roller can be adjusted, the front and back position of the idle roller can be fine-adjusted, it can be guaranteed that short materials are sent to a sanding station smoothly, and operation is easy.

Description

technical field [0001] The invention relates to the technical field of adjusting idler rollers of sanding machines, in particular to an idler roller adjustment device for short material sanders. Background technique [0002] Before the short wood enters the sanding station, it is necessary to compact the short wood to ensure the quality after sanding. The length of the short wood is short, and the general spring and idler roller are used for compression, which can only automatically adapt to the thickness of the wood, but cannot adjust the preload of the idler wheel on the short wood, resulting in jumping of the short wood during transportation. Reduced polishing quality. In addition, the distance between the two idler rollers cannot be adjusted, so short logs of different lengths cannot be conveyed, and the application range is limited. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a ...
