Abstract

The utility model discloses an envelope forming machine which is a postal machine used for producing envelopes, which comprises the mechanisms of paper feeding, printing, edge pressing, edge flanging, starch paste spreading, molding gluing, etc. The envelope forming machine can continuously accomplish the working procedures of printing, edge flanging, starch paste spreadding, gluing and so on in the process of envelope production at present, and thus the problems of low production efficiency and large labor intensity in the process of manually producing envelopes are solved. The paper form used for the envelope forming machine is a shape that both sides of the longer direction of one end on a narrow and long rectangular paper are respectively cut a small trigon, and the kind of paper form is more simple than the paper form of manually producing envelope.

Description

Envelope forming machine

The utility model is a kind of mailing machine that is used to produce envelope.

The present production process of post envelope is by printing, cut a sheet of paper, otch, flanging, being coated with paste, flanging and seven procedures such as bonding are formed, wherein print, cut a sheet of paper, operation such as otch finishes on printing machine, trimmer and slotting machine respectively, and all the other four procedures are to be finished by manual, because the operation of manual production envelope is many, the demand of post envelope is big, so manual productivity ratio is low, working strength of workers is big.

In order to overcome the above-mentioned deficiency in the manual production envelope process, the utility model has been made a kind ofly can finish printing in the envelope production process, flanging, flanging continuously, be coated with the envelope machine of paste and five processes such as bonding, is used for satisfying the needs that envelope is produced.This envelope machine productivity ratio can reach per hour 4000 envelopes.The M.G. pure sulphite paper paper shape that is used for this machine is simpler than traditional M.G. pure sulphite paper shape.

Paper shape as shown in Figure 1 be used for this envelope machine each is cut out and to go a M.G. pure sulphite paper paper shape behind the gore than length direction one end bilateral on a rectangle paper; The step that this paper shape paper is made envelope is as follows: (1) presses dotted line mm ' and nn ' flanging; (2) as shown in Figure 2, the dash area behind the flanging is coated with full paste; (3) press dotted line ss ' doubling, corresponding dash area after the doubling is compressed and bonding, promptly become envelope.

As shown in Figure 4, paper storehouse side plate (11) connects with framework lateral plate (1) by bolt (12), and framework lateral plate (1) lower end is converted into the right angle to the paper inside-of-refrigerator, as paper bottom of the reservior plate, at the base plate longitudinal middle part, locate near paper storehouse side plate (11), there is bolt (14) to be fixed on the base plate.There is aperture at bolt (14) center, and separation pin (13) is nested among the aperture with slight interference fit.Separation pin (13) is arranged in paper bottom of the reservior plate bilateral, and the trimming of being torn in the paper feeding process is clung by paste, thereby does not influence the aesthetic property of envelope.On feeding-in roll (10), fixing the stronger block rubber of adhesiveness (9) with bolt (7) and pressing plate (8); The girth of feeding-in roll (10) is about the twice of envelope length.Paper storehouse front side board (6) is connected with framework lateral plate (1) by bolt.

Printing mechanism is made up of the print roller that is embedded with the lithographic plate font (3) printing rubber roll (5) printing ink bar (19) and ink roller (18), (17), (16) etc.Printing ink bar (19) hinge is enclosed within on the axle journal of ink roller (16), and can be around this axle journal swing.When the cam (4) that is connected as a single entity with print roller (3) acts on printing ink bar right half, printing ink bar (19) rotates to clockwise direction around hinge, the left end of printing ink bar (19) rises, printing ink in the ink tank (20) is adhered on the ink roller (18), by ink roller (17) and (16), the font that printing ink is coated onto print roller (3) gets on ink roller (18) again.After cam (4) turned over effect angle to printing ink bar (19), printing ink bar (19) was returned to the position shown in the accompanying drawing 4 under the effect of heavier left-hand component.Print roller (3) row's is common lithographic plate font.The literal of lithographic plate font is a facet, with the periphery roll extrusion very stably of print roller (3), this unstable uniformity that can influence the printing type face lines is in order to reduce this instability, the diameter of print roller (3) should be enough big, preferably gets 200 millimeters to 400 millimeters.

Slow down by the two-stage belt, motor (22) reaches belt pulley (25) with power, and belt pulley (25) is divided into two-way with power again: the first drives ink roller (17) feeding-in roll (10) and print roller (3) by belt (15); It two is to drive edge roller (44) and left press bonding roller (30) down by belt (26).The gear of press bonding roller (30) end, a left side is meshed with right press bonding roller (31) end gear paste roller (36) end gear respectively, drives them and rotates; Paste roller (36) rotates by edge roller (43) in belt (2) drive again.

Two ends have the last edge roller (43) of convex shoulder with two ends the same edge roller (43) convex shoulder following edge roller (44) the formation flanging device of coupling mutually to be arranged; Flanging can make the flanging of next process parallel reliable, is difficult for broken paper.Upper hem plate (28) constitutes hemmer with lower hem plate (29), and they are linked to each other with framework lateral plate (1) by bolt.At paste roller (36) top, the paste bucket (42) that feed pipe for mortar (37) is arranged and connect with gas thread with it.Feed pipe for mortar (37) is fixed on the housiung separator (40) with nut (39) and (41).Paste flows on the paste roller (36) from paste bucket (42) through feed pipe for mortar (37), and paste roller (36) rotates, and again paste is coated onto the M.G. pure sulphite paper both sides.Screw (38) is used for regulating the paste amount that flows through feed pipe for mortar (37).

Upper and lower supporting plate (33) is connected with framework lateral plate (1) by bolt with (32); Block (34) is fixed between upper and lower supporting plate (33) and (32) by bolt (35).The parallel slit direction that upper and lower supporting plate forms becomes the angle of 40--50 with the parallel slit direction that upper and lower flanged plate (28) and (29) form.

Envelope machine described in the utility model is when operation, and feeding-in roll (10) whenever circles, and then sends a piece of paper; Print roller (3) and printing rubber roll (5) are finished the envelope printing, and are sent M.G. pure sulphite paper to the flanging device pressing, and the M.G. pure sulphite paper after the flanging is pinched by hemmer by belt (2) and (27) and to finish flanging; Then, be coated with paste by paste roller (36) in the M.G. pure sulphite paper both sides.The M.G. pure sulphite paper that scribbles paste is sent the parallel slit track that upper and lower supporting plate (33) and (32) form to by left press bonding roller (30) and paste roller (36), is blocked by block (34) up to the front end of M.G. pure sulphite paper.When the M.G. pure sulphite paper front end is blocked, the first half M.G. pure sulphite paper that enters the gap track between upper and lower supporting plate just can not readvance, and the M.G. pure sulphite paper latter half is sent into by left press bonding roller (30) and paste roller (36), so, in left and right press bonding roller (30) and top, (31) pressing district, M.G. pure sulphite paper is squeezed folding, and is admitted to left and right press bonding roller (30) and (31) pressing district.Because the M.G. pure sulphite paper both sides have scribbled paste, so through left and right press bonding roller (30) and (31) roll extrusion, the M.G. pure sulphite paper both sides are coated with the bonding envelope that promptly becomes in paste place.
