Abstract

The utility model relates to the improvement of an automatic paper folding machine, which belongs to the equipment technical field of printing and bookbinding. The utility model has the technical proposal that two shaft heads at both ends of short rubber rollers 5, 9 in an original paper folding mechanism are provided with a short rubber roll bearing seat assembly composed of a bearing supporting frames 8, 19, a bearing 17, bearing seats 15, 20. Each side of the bearing supporting frames 8, 19 is provided with tension springs 3, 7, a hole on the middle position of the side of the bearing supporting frames forms a moveable connection with supporting column 4, 12 fixed on two lateral plates of the machine frame 1, and each end of the tension springs 3, 7 is connected with spring seats 2, 6 fixed on the lateral plate. The utility model has the advantages that the structure is simple, and the regulation is easy.

Description

The layboy of paper folding adjustable in pressure

The utility model is a kind ofly can carry out the folding automation folding machine of standard form to drawing, letter, file etc., belongs to the printing bookbinding equipment technical field.

Progressively development along with office automation, duplicator, automatic mimeograph etc. have been widely used, word processing and printing office automation have been improved greatly, but the appearance of a large amount of printed matters, the post-processing aspect of particularly word processing, printing, the file paging that printing is crossed folds, binds and dress envelope or hand-manipulated, promptly not attractive in appearance also lack of standardization.Layboy in the market to the paper of different size, different fold-types can adjust, autofeed, automatically numeration, Photoelectric Detection, stepless change, automatically paper collecting; rolled over auto-stop; can roll over doubling, outer three foldings, interior three foldings, sheet sleeve folding, kwan-yin folding, six kinds of fold-types of four foldings; folding effect standard attractive in appearance; and the paper folding velocity ratio is very fast, reduces labour intensity greatly.Because in the paper foldling mechanism of this layboy, paper feeding is opened and the rubber roll that flattens folding line is fixed the position each other, and pressure can not be adjusted each other, causes the paper burst that vertical fold is arranged even tiny diagonal break is arranged, influence folding effect, and easily cause paper jam.

The purpose of this utility model is to propose a paper feeding applanation pressure and is convenient to adjust, be applicable to various paper, and folding line is attractive in appearance, is difficult for causing the layboy of the paper folding adjustable in pressure of paper jam.

The utility model is achieved in that it comprises that four are fixed on pillar on the frame biside plate, four and are through that the short top roller bearing holder assembly that can rotate on the pillar, four are fixed on the spring perch on the side plate, four extension springs are formed.Its technical essential is that short top roller bearing holder assembly can be done moving seesaw-type and rotates on pillar, and when an end during by the extension spring pull-up, the other end can drive short rubber roll and contact with the long rubber roll of fixing, generation pressure.Because this paper folding pressure regulating mechanism is the moving seesaw-type elastic construction, can realize the adjustment of pressure by adjustment spring perch angle easily, and can locate after once adjusting that complete machine must not torn cover adjustment open.

Below by Figure of description, improvement of the present utility model is described in detail: a kind of layboy of paper folding adjustable in pressure, by frame 1 and rack-mounted paper foldling mechanism, paper feed mechanism, the paper delivery mechanism sum counter constitutes, it is characterized in that being the tangent short rubber roll that contacts 5 respectively with long rubber roll 10 in the paper foldling mechanism is connected with short top roller bearing holder assembly respectively with the two ends spindle nose of lacking rubber roll 9, short top roller bearing holder assembly is by being fixed with bearing seat 15 on one side, 20, bearing seat 15, short top roller bearing 17 is installed in 20, another side is installed and is articulated an extension spring 3,7 bearing bracket 8,19 form, bearing bracket 8,19 interpositions are equipped with a hole, with the pillar 4 that is fixed on frame 1 biside plate, 12 are movably connected, extension spring 3, an end of 7 and the spring perch 2 that is fixed on the biside plate, 6 are connected.

Principle of work of the present utility model is the seesaw effect of the bar thick stick that constitutes of utilization and pillar, extension spring, short rubber roll is contacted with the pressing of long rubber roll be adjustable elastic stage.Overcome because paper thickness changes the paper folding mass defect of bringing.The utility model is identical with existing folding machine when using.Be the improvement product of existing layboy, have simple and reasonable, easy to adjust, advantage such as working stability is reliable, and result of use is good, and cost is low.

Figure of description 1 is a complete machine structure scheme drawing of the present utility model;

Figure of description 2 is front views of the short-and-medium top roller bearing holder assembly of Fig. 1;

Figure of description 3 is that the A-A of Fig. 2 is to section-drawing.

More than in three accompanying drawings, 1 frame, 2 spring perches, 3 extension springs, 4 pillars, 5 short rubber rolls, 6 spring perches, 7 extension springs, 8 bearing brackets, 9 short rubber rolls, 10 long rubber rolls, 11 small sized cots, 12 pillars, 13 block circles, 14 screws, 15 bearing seats, 16 block circles, 17 bearings, 18 screws, 19 bearing brackets, 20 bearing seats, 21 screws, 22 block circles, 23 screws, 24 screws.

Below in conjunction with accompanying drawing an embodiment of the present utility model is described in detail.

The said folding machine of the utility model is by frame 1 and be installed in that paper foldling mechanism, paper feed mechanism, paper delivery mechanism and counting control mechanism on the frame 1 form.The improvement of this folding machine is primarily aimed at the rubber roll pressure adjustmenting mechanism in the paper foldling mechanism.Bearing seat 15 usefulness screws 14,18 shown in Figure 2 are fastened on the bearing bracket 8, and extension spring 7 one ends hang in the hole of bearing bracket; Pillar 12 is fixed on outside the side plate of frame 1 by screw 24, and bearing bracket 8 middle parts are through on the pillar 12, and block circle 13, bearing bracket 8 can rotate on pillar 12 flexibly; Short rubber roll 9 two ends are inserted in the bearing seat 15, and the shaft end that bearing 17 passes short rubber roll 9 is enclosed within the bearing seat 15, block circle 16 on the axle of short rubber roll 9 outside exposing bearing 17.Spring perch 2,6 shown in Figure 1 is fixed on the outside of side plate respectively symmetrically with screw, the other end of extension spring 3,7 is hung on the spring perch.When bearing bracket 8,19 1 ends by extension spring 3,7 pull-ups, the other end will drive short rubber roll 5,9 and depress, and contacts with long rubber roll 10, produces pressure.This pressure can transmit paper and the paper burst is carried out impression.Form because this pressure is extension spring power fully, therefore only need to adjust the angle of spring perch, elongate or shorten the length of extension spring, just can realize the equalization of pressure at rubber roll two ends,, guarantee the smooth and easy of paper delivery to reach folding line effect smooth, attractive in appearance.
