Abstract

The utility model relates to an envelope mill, in particular to a device which is used to cut a window opening on the envelope cover and easily press tear line and which pertains to an envelope and a paper pocket packing technology field. The mill comprises a front roller, a front drum matched with air jacket, a knife roll matched with air jacket, a tool for cutting the window and a porcelain stick, two groups of pressure rollers at right and left side of the knife roll, a knife tool for easy tear line, a porcelain stick and a mill rack, a latter roller matched with air jacket, a latter roll, a waste paper scraps box and a waste delivering pipeline. The knife tool can be easily adjusted and applied to cut the window opening and simultaneously to suppress the tear line. The paper is wrapped to the knife roll through the suction air hole to revolve and the axis of the knife tool is at an angle of 2 degree to the porcelain stick, then the window opening can be easily scratched out and the size and the position of the window opening on the envelope and the quality can be guaranteed. The knife tool and the porcelain stick are no contacted with surplus. Thus the knife tool is low wear, long service life time, slight vibration during the working, small noise, reaching the maximum working speed at 3000 pcs / h. The utility model adopts that the paper is wrapped to the knife roll to revolve to cut the window opening on the envelope, the waste paper scraps have the resilience and the paper can be separated from the waste paper scraps so that enable the feeding paper keep in normal condition. Therefore the production efficiency is increased.

Description

Envelope maker windowing and pressure easy-torn line device

Technical field

The utility model relates to a kind of envelope maker, and particularly windowing and press the easy-torn line device wherein belongs to envelope, paper bag packing technical field.

Background technology

At present, used envelope windowing facility on the market is to adopt plane paper feed form, up-down rollers through-drive, the rolling betwixt and formula of letter paper.With the axle base of roll shaft about the screw mandrel adjustment, thereby reach the order point of adjusting the cutter gap.Waste paper scrap is inhaled on cutter by air-breathing power in the back of windowing, and then venting, waste paper scrap is arbitrarily fallen.The shortcoming of this device is: 1. adopt plane paper feed form, rolling the forming of the relative rotation with the edge bearing plate of cutter, window waste paper scrap and letter paper separation difficulty.2. cutter, edge bearing plate all are metal materials, and because of the rolling necessary magnitude of interference is big, working time one rimmer knife backing plate just shuts out tool marks, and letter paper has certain fiber to be difficult to break, and letter paper connects together with scrap and is difficult to separate.Therefore cutter and backing plate life-span are short.3. big because of cutter and the edge bearing plate magnitude of interference, strike note is big when rolling, and machine shakes, and influences bag speed and quality of item.

Summary of the invention

The purpose of this invention is to provide a kind of envelope maker with windowing and press the easy-torn line device, this device is by structural design, and material selection can improve speed and quality that cutter life and envelope are windowed.

Envelope maker windowing of the present utility model and pressure easy-torn line device comprise preliminary roller, front roll and distribution cover, rotor and distribution cover, window cutter and porcelain rod, two groups of pinch rollers about rotor, easy-torn line cutter, porcelain rod and frame, back roll and distribution cover, back roller, the waste paper scrap case with send useless pipeline.

In the use, when paper when preliminary roller is delivered to front roll A point, air-breathing paper is held of front roll is delivered to the venting of B point, and air-breathing arc plate is housed on the rotor, the arc plate is air-breathing at the B point, and paper is held rotation.Cutter is housed on the rotor, and the cutter rotation is tangent with the porcelain rod, and window in the ground paper is scraped.Suction hole is arranged in the cutter, and the waste paper scrap of will windowing holds, and exits when rotor arc plate rotates to the D point, and paper unclamps, and back roll is air-breathing in the beginning of D point, paper is inhaled rotated on back roll.Begin venting when back roll goes to the E point, the paper rectilinear motion is delivered on the roller of back and is sent to next functional areas.When cutter rotated to the D point, the window waste paper scrap separated with letter paper.Waste paper scrap is inhaled in cutter, and when cutter rotated to the F point, the cutter pore was blown from air-breathing conversion, waste paper scrap is blown out from cutter, waste paper scrap falls into the waste paper scrap case, in the waste paper scrap case conveyance conduit is housed, and conveyance conduit is transported to waste paper scrap in the waste paper scrap storehouse of machine outside.On rotor, can suppress easy-torn line by dress easy-torn line cutter, consistent with windowing cutter operation principle.

This mechanism's effect is: cutter is easy to adjust, simultaneously windowing and compacting easy-torn line.Rotate because of paper wraps on the rotor by suction hole, tool axis becomes 2 ° of angles with the porcelain rod, so be easy to window is scraped, has guaranteed size positions and window quality that envelope is windowed.The no interference of cutter and porcelain rod contacts, so tool wear is little, and the life-span is long, shakes for a short time during work, and noise is little.High operation speed reaches 30000pcs/h.Paper package roller rotation windowing, waste paper scrap is with resilience, and paper is easy to separate with waste paper scrap, makes paper energy course feed, has improved production efficiency.

Description of drawings

Below in conjunction with drawings and Examples the utility model being further specified Fig. 1 is topology view of the present utility model.

The specific embodiment:

As shown in Figure 1, paper is sent into front roll 2 by preliminary roller 1, front roll 2 is equipped with the distribution cover, four row's suction holes are arranged on the cylinder, inhale by the control of distribution cover and put the position, paper is transmitted the B point from the A point, tool roller axis 3 is equipped with air-breathing arc plate, cutter (windowing, easy-torn line) ventilation mandrel has three passages on the mandrel, and air-breathing, the blow-out position of distribution cover control is housed.Paper is transmitted the D point from the B point, and cutter 5 is separated from ground paper at the D waste paper scrap of naming a person for a particular job, and blows out to the F point.Porcelain rod 4 organic frames are fixed, and frame is installed on the wallboard with hinge, and balanced weight is housed can upwards lifts, and park arbitrarily angledly, and it is convenient to guarantee to adjust cutter.Pinch roller 6 is installed in and is pressed on the frame on the rotor, about rotor each 2 groups, can adjust the position according to ground paper size.Back roll 7 is equipped with the distribution cover, and four row's suction holes are arranged on the cylinder, has the control of distribution cover to inhale and puts the position.Paper is passed to the E point from the D point, and paper is linearly moved to back roller 8, is passed to the Xia Dao functional areas.This structure is installed on the envelope maker, as without windowing function, porcelain rod frame is lifted, and paper energy normal delivery does not influence operating rate and quality.
