Description

Technical Field

[0001] This invention relates to the field of material handling equipment technology, specifically to a thin sheet loosening roller. Background Technology

[0002] In the field of material handling equipment technology, the loosening of sheet materials is an important operational step. Currently, existing sheet loosening rollers on the market face many challenges in practical applications.

[0003] Firstly, traditional loosening rollers have significant shortcomings in the installation of bevel gears. Since the shaft spacing is often fixed, precise alignment is difficult to achieve during installation, leading to installation deviations. Furthermore, the installation process typically requires complex tools and cumbersome steps, which not only greatly reduces installation efficiency but also results in poor stability of the installed bevel gears, making them unable to withstand large transmission torques and proving inadequate for handling various complex material processing scenarios.

[0004] Secondly, existing technologies also have shortcomings in the cleaning and maintenance of loosening rollers. When loosening thin materials, material is easily left on the surface of the loosening roller. If this material is not cleaned in time, it will gradually accumulate and have an adverse effect on the loosening effect. However, traditional cleaning methods are either inefficient or have a complex structure, which cannot meet the needs of efficient cleaning in actual production.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. This type of thin-sheet loosening roller features a rotating connecting ring that is connected to two sleeve grooves at both ends of the loosening roller. The connecting ring contacts the sleeve grooves via balls, reducing rotational friction. One end of the rotating shaft is fixed inside the sleeve groove, and the outer surface is threaded to a rotating ring. Through the sliding engagement of a slider and a groove, the sleeve shaft can move axially along the rotating shaft.

A threaded limiting plate is connected to the connecting groove at the end of the sleeve shaft.

[0018] 2. This type of thin-sheet loosening roller is driven by a motor on the support block to rotate gear two. Gear one meshes with gear one, which in turn drives the connecting arm and the sleeve rod to rotate. The two ends of the support arm are respectively sleeved on gear one and the sleeve rod of the side block, forming a crank-slider mechanism. When gear one rotates, the support arm drives the side block to slide back and forth in the side groove. The connecting rod drives the sliding block to reciprocate in the sliding groove. The cleaning brush under the sliding block moves back and forth with the sliding block, closely adhering to the surface of the loosening roller to clean residual materials, avoiding material accumulation that affects the loosening effect. The arc-shaped baffles on both sides of the cleaning brush can prevent material from splashing during the cleaning process, improving cleaning efficiency and the cleanliness of the working environment.
