Abstract

The utility model relates to a paper separating folding device for a transfer printing machine, which comprises a double roller composed of a knife roller and a groove roller. The utility model is characterized in that two grooves are symmetrically arranged above the knife roller along 180 DEG of an axial direction, an indentation knife frame and a paper separating knife frame which can be slid in the grooves up and down are respectively arranged in the two grooves, an indentation knife and a paper separating knife are respectively arranged on the indentation knife frame and the paper separating knife frame, two ends of each of the two knife frames exposed out of the knife roller are connected with draw springs, the two ends of each knife frame are respectively provided with a rolling wheel, and an eccentric cam which is matched with the rolling wheel to make the paper separating knife and the indentation knife moved up and down in a period mode is fixed on a machine frame. The utility model has the advantages of simple structure and convenient and uniform fold. The utility model can correctly press out a folding indentation line at the center of paper and avoids paper waste.

Description

Rotary press separation folding apparatus

The utility model belongs to printing equipment, and the nothing of using on particularly a kind of rotary press is held pin separation folding apparatus in the month.

Separation on the existing rotary press and folding are by the separation cutter, hold roller groups such as pin and clamping plate in the month and constitute, the termination of the paper after cutting is to hold pin in the month with a row to drag sheet movement, so just stay a round hole at the edge of every paper, in the bookbinding of subsequent processing, just must be with the part paper excision in hole with holes, not only complex structure, cause paper waste again, simultaneously when binding folding next time, indeterminate because of the folding midline position, make not only inconvenience but also irregular of folding work.

The purpose of this utility model is that design is a kind of simple in structure, and folding is convenient neat, does not waste the rotary press separation folding apparatus of paper.

Task of the present utility model is to realize like this, it includes the separation pair roller of being made up of rotor and grooved roller, it is characterized in that: 180 degree are arranged with two grooves vertically on rotor, the knife rest that can slide up and down in groove is housed respectively in two grooves, separation cutter and impression cutter are housed respectively on two knife rests, the two ends of exposing rotor at two knife rests are connected with extension spring, the knife rest two ends also are respectively equipped with a roller, cooperate with roller to make the eccentric cam that is fixed on the frame that has that separation cutter and impression cutter cycle move up and down.

The utility model so it is simple in structure, and can extrude the trace of folding accurately line owing to the needle construction of holding in the month with complexity becomes one group of pair roller in the center of paper, and folding is convenient neat, avoids paper waste.

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

Fig. 2 is the cutaway view of separation pair roller.

The drawing explanation: 1. rotor 2. grooved rollers 3. feed rollers 4. defeated paper tape 5. impression knife rests 6. rollers 7. eccentric cams 8. draw bullet 9. separation knife rests 10. folding machines

Further describe embodiment in conjunction with above accompanying drawing.The utility model rotary press separation folding apparatus, it includes the separation pair roller of being made up of rotor 1 and grooved roller 2,180 degree are arranged with two grooves vertically on rotor 1, the impression knife rest 5 and the separation knife rest 9 that can slide up and down in groove are housed respectively in two grooves, separation cutter and impression cutter are housed respectively on two knife rests, separation cutter blade and the equal indentation of impression cutter blade, but the cutter tooth of separation cutter is small and dense, during separation paper is cut off fully, and the cutter tooth of impression cutter is bigger, only cut half of tooth depth during impression, letterweight is gone out row's trace line, the two ends of exposing rotor 1 at two knife rests are connected with extension spring 8, and each knife rest two ends is respectively equipped with a roller 6, cooperate eccentric cam 7 that is fixed on the frame in addition that separation cutter and impression cutter cycle are moved up and down with roller 6.

During work; paper after the printing is by dragging paper bowl paper to be sent in the roll gap of rotor 1 and grooved roller 2; when roller 6 moves to eccentric cam 7 contacted positions; eccentric cam 7 heads on roller 6 on the side tool post to a certain amount of distance of grooved roller 2 one side shiftings; impression cutter or separation cutter are contacted with paper on the pair roller; paper is extruded one vestige or cuts paper; to be cut into the paper of opening by feed rollers 3 and defeated paper tape 4 and be sent to folding machine 10; because of center, the vestige position that extrudes at paper; the folding and the bookbinding of next procedure have so just been made things convenient for; both folding was convenient neat, avoided the waste of paper again.

Claims

1, rotary press separation folding apparatus, it includes the pair roller of being made up of rotor and grooved roller, it is characterized in that: 180 degree are arranged with two grooves vertically on rotor, the impression knife rest and the separation knife rest that can slide up and down in groove are housed respectively in two grooves, separation cutter and impression cutter are housed respectively on two knife rests, the two ends of exposing rotor at two knife rests are connected with extension spring, each knife rest two ends also is respectively equipped with a roller, and cooperating what make that separation cutter and impression cutter cycle move up and down with roller is an eccentric cam that is fixed on the frame.

2, rotary press separation folding apparatus according to claim 1 is characterized in that: the separation cutter with or the equal indentation of blade of impression cutter, the cutter tooth of impression cutter is bigger.
