Abstract
The utility model relates to a metering roller clearance adjusting mechanism which is suitable for producing aluminum oxide wear-resistant impregnated paper, aims to realize a retaining function of a clearance adjusting mechanism, has high precision, and is convenient to use. A metering roller clearance adjusting mechanism with a retaining function comprises a transmission crank arm; an adjusting metering roller is mounted at the upper end of the transmission crank arm, and the lower end is hinged with a piston rod of a push cylinder; a bearing shaft at the middle of the transmission crank arm is horizontally mounted on a rack; the clearance adjusting mechanism is characterized by further comprising a worm-gear speed reducer; the worm-gear speed reducer and the push cylinder are located on the two sides of the transmission crank arm respectively; and the worm gear head of the worm-gear speed reducer is horizontally arranged and extends out toward the transmission crank arm. The worm-gear speed reducer is a manually-operated worm-gear speed reducer.
Description
Technical field
The utility model relates to the facing paper production technical field, is specifically related to a kind of metering roll gap adjusting mechanism, is applicable to that producing alundum (Al carries wear-resistant immersion paper.
Background technology
Carrying in the wear-resistant immersion paper production process at alundum (Al, is to limit the facing paper spread through the gap of adjustment metering roll.As shown in Figure 1, usually, frame is provided with fixedly a metering roll and an adjusting metering roll, regulates metering roll and is furnished with gap adjusting mechanism; Conventional gap adjusting mechanism generally comprises a transmission crank arm that is used to install said adjusting metering roll; The middle part of transmission crank arm is installed on the frame through the load-bearing axle, and the lower end is connected with a promotion cylinder, promotes to promote when cylinder stretches the transmission crank arm swing; In addition; One side of transmission crank arm also is provided with a screw rod that is used to hold out against said transmission crank arm, and this screw rod and the both sides that promote cylinder apportion transmission crank arm are through controlling the length that screw rod stretches out; Can regulate the distance that the piston rod that promotes cylinder stretches out, thereby regulate the gap of metering roll.The defective of this type of gap adjustment structure is that the back screw rod that works long hours is loosening easily, and does not have stopping function, influences the gap adjustment precision of metering roll, causes certain influence for the quality of product.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes in the above-mentioned background technology, and a kind of improvement of metering roll gap adjusting mechanism is provided, and this gap adjusting mechanism is answered stopping function, also has precision height, characteristics easy to use simultaneously.
For realizing above purpose, the technical scheme below the utility model has adopted:
A kind of metering roll gap adjusting mechanism with stopping function; Comprise a transmission crank arm, the upper end of this transmission crank arm is installed with the adjusting metering roll, and the lower end is hinged with the piston rod that promotes cylinder; The load-bearing axle horizontal at transmission crank arm middle part is installed on the frame; It is characterized in that: said gap adjustment structure also comprises a worm reduction gear, the both sides of this worm reduction gear and said promotion cylinder apportion transmission crank arm, and the worm gear head horizontal arrangement of worm reduction gear and stretch out towards said transmission crank arm.
Said worm reduction gear is the hand worm reduction gear.
The beneficial effect of the utility model is: the utility model uses worm reduction gear to substitute conventional screw rod; Thereby improved the precision of metering roll gap adjustment; And worm reduction gear itself has auto-lock function, thereby can prevent that the worm gear head is loosening and retreat, and guaranteed the stable of product quality; And easy to use, the cost after the improvement is also comparatively cheap.
Description of drawings
Fig. 1 is the main TV structure sketch map of the utility model.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described further, but the utility model is not limited to following examples.
As shown in the figure; A kind of metering roll gap adjusting mechanism with stopping function; Comprise a transmission crank arm 2, the upper end of this transmission crank arm is installed with regulates metering roll 7, and the lower end is hinged with the piston rod that promotes cylinder 1; Load-bearing axle 5 levels at transmission crank arm middle part are installed in (frame is omitted and do not drawn) on the frame; This load-bearing axle can also make transmission crank arm rotate around its axis when bearing weight, and it is characterized in that: said gap adjustment structure also comprises a worm reduction gear 4 (being installed on the frame); The both sides of this worm reduction gear and said promotion cylinder apportion transmission crank arm, and worm gear head 3 horizontal arrangement of worm reduction gear and stretch out towards said transmission crank arm.
Usually, said worm reduction gear is recommended to adopt the hand worm reduction gear, is conventional equipment, and buyable obtains, and its operation principle and structure do not describe in detail.
Operation principle of the utility model and conventional metering roll gap adjusting mechanism are similar, and difference is that the utility model uses worm reduction gear to substitute conventional screw rod, thereby has stopping function, and precision is higher.
Also have among the figure, fixedly metering roll 6.
