Abstract

The utility model relates to a spraying apparatus, comprising a motor, a gearing device and a material storing chamber. A material coating mechanism is formed by that two pairs of rotary shafts and scrapers are arranged in parallel, wherein, one or a pair is a coating roll shaft, and the others are workpiece conveying roll shafts; the rotary directions of two upper shafts and two lower shafts are respectively coincident, and the rotary directions of the upper shafts and the lower shafts are opposite; the scraper controls the feeding thickness of the coating roll shaft; in addition, a plurality of hand wheel regulating mechanisms regulate the gaps between the upper shafts and the lower shafts and the distance between the scraper and the coating roll shaft. The utility model has the advantages of simple structure, low cost, convenient adjustment and operation and uniform coating material.

Description

A kind of coating machine

The utility model relates to a kind ofly coats the device on surface to liquid or other flowing materials, specifically to the machine of the moistureproof oil that adds lustre to of corrugated case surface coating.

Last procedure that present middle-size and small-size carton factory is produced at corrugated case---when the coating protection against the tide of carton surface adds lustre to oil, adopt the method for hardened coating mostly.Hardened coating labour intensity is big, and production efficiency is low and crawling even.A kind of double machine that oils that prints is also arranged.But every in this machine is more than five, 60,000 yuan, and is expensive and be used for the processing of small lot carton and be not suitable for.In addition, the operation, the plate-making personnel will be through special training.

The purpose of the utility model be to society provide a kind of simple in structure, operation is easy to adjust, coating coating machine even, with low cost.

The utility model is achieved in that it comprises frame, motor, transmission device, stock chest.Its coating mechanism is provided with the rotation roll shaft of two pairs of arranged parallel, one of them or a pair of be the coating roll shaft, surplusly be that workpiece carries roll shaft, every pair of roll shaft is one on the other, middle gapped, two of the two pairs of roll shafts rotation directions that go up roll shafts and two lower roller shafts are identical respectively, and the direction of rotation of roll shaft up and down.Coating mechanism also is provided with scraper plate, and side and coating roll shaft that this scraper plate is placed in the coating roll shaft have certain interval, are controlling the thickness of coating roll shaft material loading.Several handwheel governor motions are arranged, and this mechanism is installed in the top of roll shaft or the side of side or scraper plate.

Such coating machine advantage is: because workpiece is carried the effect of roll shaft, it is steadily moving that workpiece is sent to the time shift of coating roll shaft.Because the scraper plate of coating roll shaft side is being regulated the thickness of material roller material loading, so the workpiece surface coating uniformity.Because the top of roll shaft or the side of side or scraper plate are provided with governor motion, the gap between up-down rollers between centers and scraper plate and roll shaft can be regulated, so this machine is big to the thickness of workpiece accommodation of need coating, the paint thickness of surface of the work can accurately be controlled.

During use,, workpiece carries roll shaft, the coated layered material of surface of the work that comes out from the material roller axle as long as being pushed lifting workpiece.If the coating roll shaft is upper and lower a pair of, then the material coated of workpiece is two-sided; If the coating roll shaft be one (have in addition an axle also do workpiece carry with) then the material that surface of the work is coated is a single face.The utility model is simple in structure, and cost of manufacture is low, operates easy to adjustly, and coating evenly.

Describe the utility model embodiment in detail below in conjunction with accompanying drawing.Motor 21 is installed in of frame 20 (seeing Fig. 2,3).Transmission device comprises driving-belt 19, the belt pulley 18 of workpiece conveying roll shaft 4 one ends, the gear drive 22 of axle 4 other ends.The stock chest of coating machine divides goes up hopper 15 and blanking groove 9.Gear drive comprises the driving gear Z1 (see figure 5) of workpiece conveying roll shaft 4 other ends down, the right gear Z2 that driving gear Z1 directly drives, following compound gear Z5, Z6 and left gear Z10; The top workpiece conveying roller shaft gear Z4 that cog Z3 and the gear Z3 that is driven by driven gear Z2 drives; By the lower-left gear Z7 that following compound driven gear Z5, Z6 drive, be connected in the gear Z8 on the gear Z7 left side, the following coating roll shaft gear Z9 that gear Z8 drives; By last compound gear Z11, the Z12 that driven gear Z10 drives, the top coating roll shaft gear Z13 that last compound gear drives.Coating mechanism is provided with the rotation roll shaft of two pairs of arranged parallel.Workpiece conveying axis 1 and 4 (see figure 1)s in front,

coating roll shaft

12,13 is put behind.

Last roll shaft

1,13 clockwise rotates, lower roller shaft rotates counterclockwise.The coating roll shaft is made up of axle, the outer field plastic tube 10 of axle and flexible material lint 8.Upper and lower scraper plate is formed by scraping panel seat 5, rubber scraping article 6 and pressing plate 7.

Handwheel governor motion

11,17,14,16 places down coating roll shaft 12 and upper scraping plate side (each one at two ends) respectively and coats the top (each one at two ends) that roll shaft 13 and last workpiece carry roll shaft 1.The handwheel governor motion can be made up of along slipper bearing 25 and compression spring 26 that guide rail slides adjusting handle, screw mandrel 23 (see figure 4)s, guide rail 24.

Can operate after adjusting the interval in gap and rubber flap and coating roll between centers between two pairs of upper and lower axles.Back corrugated case 3 (see figure 1)s of machining pushed the workpiece conveying axis at 1,4 o'clock from platen 2, and

axle

1,4 moves the steady constant speed of carton to

coating roll shaft

12,13, oil by the corrugated case of coating roll shaft is two-sided.The utility model embodiment has made model machine, and result of the test shows energy two-sided oil simultaneously (carton becomes rugosity), coating is even, more than 20%, work efficiency has but improved more than ten times to materials, and has alleviated labour intensity greatly than the manual method minimizing.Machine construction compactness, running steadily operates easy to adjust and cost only is coated with 1/10th of two-purpose machine for printing.

If will coat roll shaft 13 or down coating roll shaft 12 change workpiece into and carry roll shaft, then the utility model becomes single face material loading coating machine.
