Abstract

The invention discloses a paper making edge cutting device. Edge cutting squirt cuts are arranged between a cylinder and a back roller; the external side of the back roller is provided with an edge fixing wheel that is in contact with a roller surface; in the production process, excessive edges are cut by the squirt cuts, and the cut edges are conveyed to the back roller; the back roller and the edge fixing wheel are in surface contact; the back roller drives the edge fixing wheel to rotate reversely, and pulp cut by the edge cutting squirt cuts is piled up on the edge fixing wheel; the pulp is rinsed continuously by an outflow tube, and the rinsed pulp refluxes in a pulp raw material tank through a pipeline for recycling. After the adoption of the device, winding synthetic leather on the cylinder when paper with various sizes is produced is not required, therefore, wear between a cylinder face and a cylinder edge can be reduced, and the cylinder face can be protected well, and the service life of the cylinder face can be prolonged by 2-3 times.

Description

The papermaking trimming device

Technical field

The present invention relates to field of papermaking, particularly finish the device of side cut in the paper-making process.

Background technology

One cover paper making equipment generally need be finished the paper production of multiple dimensions, existing way be the cylinder both sides around on synthetic leather, make the wire side width of producing paper and to produce paper width consistent, be not stained with paper pulp, so just can produce the paper of the width that requires owing to synthetic leather; There is a serious defective in process of production in this way, is exactly the friction between synthetic leather and the wire side (nylon or polyesters), is easy to make wire side and selvage impaired, generally be to change one time wire side in 3～4 days, the one, influence production efficiency, the 2nd, waste is serious, increases production cost.

Summary of the invention

Defective at prior art exists the object of the present invention is to provide a kind of papermaking trimming device, use this device after, need on cylinder, not wrap finished leather when producing the paper of all size, protected wire side preferably, the life cycle of prolongation wire side.

The objective of the invention is to be achieved by the following technical programs: the papermaking trimming device, comprise cylinder and roller later, it is characterized in that, cylinder with later be provided with trim shower between the roller, the described roller later outside is provided with the deckle that contacts with its roll surface and takes turns.

The further technical scheme of the present invention is, the deckle wheel with turn one's head the width that roller contacts and equate with the side cut width.

By trim shower with under the unnecessary sideline judge; be transported to roller later then; later roller takes face to contact with the deckle wheel; later roller strap moves deckle crop rotation counter-rotation; at this moment the paper pulp under being cut out by trim shower is deposited on the deckle wheel; uninterrupted flushing by outlet pipe; paper pulp under being rinsed is back in the paper pulp raw material pond by pipeline and recycles; after adopting this device; need on cylinder, not wrap finished leather when producing the paper of all size; reduce the wearing and tearing of wire side and selvage, protected wire side preferably, the life cycle of wire side prolongs 2～3 times.

Description of drawings

Fig. 1 is a geodesic structure schematic diagram that waits of the embodiment of the invention;

The specific embodiment

As shown in Figure 1, papermaking trimming device provided by the present invention, cylinder 1 and later be provided with trim shower 3 between the roller 2, later roller 2 outsides are provided with the deckle wheel 4 that contacts with its roll surface, deckle wheel 4 with turn one's head the width that roller 2 contacts and equate with the side cut width, deckle wheel 4 is fixedly installed on the frame, and its position can be adjusted according to the side cut width.In the production process; by trim shower with under the unnecessary sideline judge; be transported to roller later then; later roller takes face to contact with the deckle wheel; later roller strap moves deckle crop rotation counter-rotation; at this moment the paper pulp under being cut out by trim shower is deposited on the deckle wheel; uninterrupted flushing by outlet pipe; paper pulp under being rinsed is back in the paper pulp raw material pond by pipeline and recycles; after adopting this device; need on cylinder, not wrap finished leather when producing the paper of all size, reduce the wearing and tearing of wire side and selvage, protect wire side preferably.

Present embodiment only is a better embodiment of the present invention; describe technical conceive of the present invention and essential implementation in detail; be not to be that protection scope of the present invention is limited; all spirit essence is done according to the present invention any simple modification and equivalent structure transformation or modification all should be encompassed within protection scope of the present invention.

Claims

1. papermaking trimming device comprises cylinder and roller later, it is characterized in that: cylinder with later be provided with trim shower between the roller, the described roller later outside is provided with the deckle that contacts with its roll surface and takes turns.

2. papermaking trimming device according to claim 1 is characterized in that: deckle wheel with turn one's head the width that roller contacts and equate with the side cut width.
