CN202805749U - Draft gear for high-strength corrugated combination board - Google Patents

Abstract

The utility model relates to a draft gear for high-strength corrugated combination board. The draft gear for high-strength corrugated combination board comprises a rack, a driving roller and a pressure roller, wherein both sides of the driving roller are horizontally hinged on the rack, the pressure roller is gear-shaped and the gear of the pressure roller matches with the corrugated shape on the corrugated combination board, the pressure roller is also provided with a lifting device that are compression cylinders, each of the two compression cylinders is fixed on the rack respectively and each of the two sides of the pressure roller is hinged to the free ends of the corresponding compression cylinders. According to the draft gear for high-strength corrugated combination board, the corrugated shape on the corrugated combination board is prevented from being squashed when the corrugated combination board enters the draft gear, thereby the quality of high-strength corrugated combination board is improved and the production efficiency is further improved.

Description

The draw-gear of high-strength corrugated composite paperboard

Technical field

The utility model relates to a kind of draw-gear of corrugated paper, particularly relates to a kind of draw-gear of high-strength corrugated composite paperboard.

Background technology

In the draw-gear of existing high-strength corrugated composite paperboard, because carry-over pinch rolls are circular roller types, when corrugated paper passed through draw-gear, carry-over pinch rolls can flatten the corrugation on the corrugated paper, have had a strong impact on like this quality of production, and production efficiency is low.

The utility model content

In view of this, for solving the deficiency of technique scheme, the utility model provides a kind of draw-gear of high-strength corrugated composite paperboard, pass through the technical program, corrugation on the corrugated paper is crushed, can improves the quality of production, production efficiency also improves greatly simultaneously.

In order to achieve the above object, the technical solution of the utility model realizes like this: the draw-gear of high-strength corrugated composite paperboard, consisted of by frame, live-roller and hold-down roller, and described live-roller both sides are horizontally hinged on frame, and hold-down roller is gear-like;

Gear on the described hold-down roller and the corrugation shape on the corrugated paper match;

Also be provided with lowering or hoisting gear on the described hold-down roller; Described lowering or hoisting gear is the compressing cylinder, and two compressing cylinders are separately fixed on the frame, and the hold-down roller both sides are hinged on respectively on the movable end of corresponding compressing cylinder;

The beneficial effects of the utility model are: by the technical program, when having stopped corrugated paper and entering draw-gear, the phenomenon that corrugation can be crushed has improved the product quality of high-strength corrugated composite paperboard greatly, thereby has further improved production efficiency.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the partial enlarged drawing of K part among Fig. 1.

Among the figure, 1 frame, 4 live-rollers, 5 hold-down rollers, 6 compressing cylinders

The specific embodiment

Below in conjunction with accompanying drawing the technical solution of the utility model is described further.

As shown in Figure 1 and Figure 2, the draw-gear of high-strength corrugated composite paperboard is made of frame 1, live-roller 4 and hold-down roller 5, and described live-roller 4 both sides are horizontally hinged on frame 1, and hold-down roller 5 is gear-like; Gear on the described hold-down roller 5 and the corrugation shape on the corrugated paper match; Also be provided with lowering or hoisting gear on the described hold-down roller 5; Described lowering or hoisting gear is separately fixed on the frame 1 for 6, two compressings of compressing cylinder cylinder 6, and hold-down roller 5 both sides are hinged on respectively on the movable end of corresponding compressing cylinder 6.

When corrugating media entered draw-gear, hold-down roller 5 compressed corrugating media in the process of rotating, because the gear on the hold-down roller 5 is identical with the corrugation shape, thus corrugation can not flattened, thus the quality of the product that improves.

The above is preferred embodiment of the present utility model only, is not be used to limiting protection domain of the present utility model, also is to belong to protection domain of the present utility model if similar modification is arranged.
