Abstract

PURPOSE:To crush and press a web of waste paper by placing a pair of rolls in such a manner as to form mutually engaging wavy grooves on the outer circumferences, making the engaging gap between the rolls to be adjustable and introducing a web between the rolls. CONSTITUTION:Wavy grooves 15a, 16a are formed on the outer circumferences of a pair of rolls 15,16 and the rolls are placed in a state to engage the grooves with each other. The gap between the rolls is made to be adjustable with a screw and a spring. A sheet web 13 is crushed and pressed by passing through the gap between the rolls.

(Function) Along with forming wave-shaped grooves on the outer peripheral surface of the pair of rolls,
A sheet-like web is passed between these rolls, which are arranged so as to mesh with each other, and as the web is bitten, it is sandwiched between the rolls, further stretched along the corrugated grooves, and crushed. At the center of the meshing point of the rolls, the web is then compressed by the pressure of the rolls to reduce bulk and densify the crushed web.

The waste paper collected in FIG. 5 is placed in a waste paper collection box 10 and supplied to a waste paper processing machine. Waste paper 11 is in collection box 10
It is taken out by a take-out conveyor 12, conveyed in the form of a web 13 by a belt, and crushed by a crushing press roll 15, 16.
sent to. Water is applied to both sides of the paper through a shower nozzle 14 to add water to the paper before passing it through the rolls in order to reduce its bulk and increase its density. The crushing and pressing rolls are a pair of rolls 15゜1 with corrugated grooves formed on the outer peripheral surface on a frame F.
6 are arranged so that their waveforms mesh with each other, as shown in FIG. It is fixed on a supported arm 19 by a rotating bearing.The gap between the upper and lower crushing and pressing rolls 15 and 16 is adjusted by setting the minimum gap using a screw 21, and by setting the pressing force between the rolls using a spring 20. These constitute an adjusting pressure mechanism that adjusts and presses the meshing gap between the rolls 15 and 16.

Now, the web 13 (waste paper 11 or the state in which it is caught by the conveyor belt and flowing in a band shape) is the shower 1
After water is added in step 4, it is fed between crushing and pressing rolls 15 and 16, and the corrugated grooves 1 of the rolls are formed as shown in FIGS. 1 to 4.
5a, 16a, and some of the water is squeezed out and received by the water pan 22, and circulated by the pump 23 to the shower nozzle 14 as part of the shower water to be reused. The crushed and pressed waste paper 24 is stored in a container 25 and collected. In addition, as a method for facilitating collection, there is also a method of compression molding the waste paper 24 using a molding machine 26 shown in FIG. 6 to form a block-shaped waste paper 27.
