Abstract

The utility model relates to an air suction opening for a rewinding machine, which aims to provide the air suction opening for the rewinding machine which can be used for stably collecting a cut paper edge so as not to ensure the production quality of finished paper. The technical scheme is that the rewinding air suction opening is communicated with a fan through a pipeline to absorb the paper edge generated by cutting with an edge cutter. The rewinding air suction opening is characterized in that the cross section of the rewinding air suction opening is flat, and the rewinding air suction opening is positioned below the edge cutter and a paper cutting point. The position of an air inlet in the front end of the rewinding air suction opening is a diagonal plane, and the cross section of the rewinding air suction opening is rectangular.

Description

The rewinding inlet scoop

Technical field

The utility model relates to a kind of paper making equipment, particularly relates to the inlet scoop that is used for rewinding machine.

Background technology

Rewinding machine is a kind of specialized equipment of papermaking, and its effect is that the paper roll 5 that paper machine is produced is carried out becoming finished paper after the rewinding successively.Because the paper roll that paper machine batched is comparatively soft; Paper roll both sides of the edge unfairness and have burr; Therefore paper roll can not directly be used for further processing or printing, must through winder trim, cut with joint after, rewinding one-tenth has behind the finished roll of certain specification and tightness and dispatches from the factory after the ability.

There are some defectives aborning in existing homemade rewinding machine: forward deflector roll 3 backs (sense of motion is shown in arrow A among Fig. 1) after body paper Y cuts through the limit cutter to; Finished paper is separated the back and is formed finished roll 8 with trimming 7, the trimming is drawn onto on the compress by blower fan through the inlet scoop and handles; Divide the trimming width scale off to be generally 3 centimetres to 5 centimetres, the trimming arrives 50 centimetres of the distances of inlet scoop after the limit cutter is cut, and the inlet scoop diameter is 15 centimetres.

Owing to receive the influence of deflector roll 3 high speed rotating, and the width on trimming is much smaller than the diameter of inlet scoop in moving process on the trimming, and the cut point of limit cutter is also distant apart from the inlet scoop, so the trimming can produce frequent shake; The shake the trimming with cut after finished paper can bump; Because the intensity of finished paper is less, the edge of finished paper very easily produces breach in the collision, in the printing house or impregnation factory add and rupture easily man-hour; Not only cause the reduction of production efficiency, and productive costs is improved greatly.

Summary of the invention

The purpose of the utility model is the deficiency that overcomes in the above-mentioned background technology, and the improvement of a kind of rewinding machine inlet scoop is provided, and the trimming after the cutting should stably be collected in this rewinding machine inlet scoop, to guarantee the quality of production of finished paper.

The technical scheme that the utility model adopts is: the rewinding inlet scoop; Pass to the absorption trimming that the cutter cutting is produced through the limit mutually through pipeline and blower fan; It is characterized in that the cross-sectional plane of said rewinding inlet scoop is the below that flats and this rewinding inlet scoop are positioned at limit cutter and scraps of paper cut point.

The front end ventilation inlet place of said rewinding inlet scoop is a diagonal plane, and the cross-sectional plane of rewinding inlet scoop is a rectangle.

The beneficial effect of the utility model is: through the rewinding machine inlet scoop being transferred to the below of limit cutter; Rotate without deflector roll on the trimming just can get into the rewinding machine inlet scoop; And the rectangular cross section of rewinding machine inlet scoop and the shape on trimming are comparatively mated, and help the stable transfer on trimming, have so just eliminated the jitter phenomenon on trimming; Therefore the end face of finished paper is more level and smooth neat, has promoted product design greatly; And this apparatus structure simpler production is convenient, and result of use has reached the purpose that expection is set fully.

The specific embodiment

Rewinding inlet scoop 1 as shown in Figure 2, blower fan is equipped with in this rewinding inlet scoop, can absorb through the limit cutter 2 cutting trimmings 7 that sheet edge produced; The rewinding inlet scoop places the below (moving to the top of deflector roll 3 from the below that was positioned at deflector roll 3 originally) of limit cutter and scraps of paper cut point R; The front end of rewinding inlet scoop is for being made into a diagonal plane 4; The cross-sectional plane of rewinding inlet scoop is that rectangle (be advisable for 4 centimetres with 8 cm x by size; Such size just matches with the width on trimming, helps limiting the trimming and in the rewinding inlet scoop, shakes, and reduce the influence of place, rewinding inlet scoop wind-force to finished paper); The rewinding inlet scoop communicates with blower fan through a round tube 6; Round tube is processed (diameter of round tube is advisable with 10 centimetres, and the wind-force that enables blower fan is effectively utilized, and can observe the mobile status of trimming in round tube) for the high-strength transparence pipe; The speed of a motor vehicle controller interlocking of the blower fan of rewinding inlet scoop and rewinding machine, the wind-force size of rewinding inlet scoop can cooperate the cutting speed in feet per minute of the scraps of paper so effectively according to the operating speed automatically regulating of rewinding machine, helps in time collecting the scraps of paper; When rewinding machine started, blower motor moved with 30Hz, and blower fan moves with 50Hz when the operating speed of rewinding machine is 1500m/min.

Claims

1. rewinding inlet scoop (1) passes to the absorption trimming that cutter (2) cutting is produced through the limit mutually through pipeline and blower fan, it is characterized in that the cross-sectional plane of said rewinding inlet scoop is the below that flats and this rewinding inlet scoop are positioned at limit cutter and scraps of paper cut point (R).

2. rewinding according to claim 1 inlet scoop is characterized in that, the front end ventilation inlet place of said rewinding inlet scoop is a diagonal plane (4), and the cross-sectional plane of rewinding inlet scoop is a rectangle.
