Abstract

The invention is a method of scrawling the colored design on the surface of the soles, the traditional scrawling methods are the transfer of hot viscous materials, spraying and priming (impressing). All of the methods are operated by hand, so the scrawling quality is bad and the productive efficiency is low. The invention is adopted the scrawling method to scrawl the colored design on the soles, thereby resolving the defects of the manual operation, providing great contribution to the shoemaking industry.

Description

The method of coated multicolour pattern on sole surface

The present invention relates to a kind of on the surface of sole the automatic method of coated multicolour pattern.

Usually, the traditional prior art method that is used on the surface of sole forming multicolour pattern has three kinds.These methods and the problem that exists separately are as follows.

(A) hot sticky material transfer method.This method is that a kind of sizing is fixed on the needed position of sole 101, sole is coated with last layer printing ink through heating, and then sizing is removed from sole.This method is owing to the manual mode of operation of taking single-piece, thereby manufactured goods are with low quality, and production efficiency is very low.This mode of production relies on operator's qualification simultaneously, thereby product quality is very inconsistent.

(B) spraying process.This method is that the pattern that need form on sole 101 is made original pattern, be attached to original pattern on the sole after again spraying go up needed colour.Yet this method is difficult to form accurate and exquisite pattern, is unsharp near the boundary line on the pattern between the different colours.Therefore, the quality of product and production efficiency are not high.

(C) linging method or stamped method.This method is at the identical die made from the outer surface of sole 101 of triple curve part, and after being coated in printing ink on this stamp surfaces, by heating die is pressed on the sole 101.The shortcoming of this method is that end product quality and production efficiency are low, and can not guarantee the high-quality requirement to the product proposition.

The purpose of this invention is to provide a kind of method that on the surface of sole, forms the coating that has multicolour pattern automatically.

Fig. 2 is a generalized section of carrying out the critical piece in the technological process of method of the present invention;

Fig. 3 A-3F is illustrated in the process that forms the coating that has multicolour pattern on the sole;

Fig. 4 is the schematic diagram that is used for sole as shown in Figure 1, that carry out the technological process of the inventive method, anchor clamps, suspension hook and carrier chain combination.

The label of the critical piece that uses in the accompanying drawing:

101. sole 102. heaters

As Fig. 3,4 and shown in Figure 1, when clamping on the sole stationary fixture 4 behind the sole 101, these anchor clamps 4 are installed on the suspension hook 3.It is unidirectional mobile continuously that suspension hook 3 is pressed the arrow direction indication along carrier chain 2.So suspension hook is transported to the front of push pedal 5, at this moment, push pedal 5 just sends these anchor clamps 4 to waiting there automatic arm 6.At this moment, automatically arm 6 is just shifted to water tank 10, there, soften processing and afloat polyvinyl acetate ester film 12 and ink lay 13 are used to be layed onto on the surface of sole 101 by the program of design.After coating was finished, these anchor clamps 4 were transmitted to the receiving system 15 that is waiting.Receiving system 15 is just Rotate 180 ° at this moment, then these anchor clamps 4 is sent to the suspension hook 3a on the carrier chain 2a, and this carrier chain also is among moving continuously.When anchor clamps 4 process rinse baths 16, the polyvinyl acetate ester film 12 on the sole 101 on the anchor clamps 4 is cleaned totally, and when anchor clamps 4 process air injection tubes 17, water droplet residual on the sole 101 is by Ex-all.Then, pass through hot air dryer 18 more afterwards just with the complete Ex-all of the moisture on the sole 101, and make the protective finish agent of anoint China ink layer 13 on the sole 101 again, anchor clamps 4 also are sent to finished product collecting chamber 22 at last again through hot air dryer 21 again.

Shown in attached Fig. 1 and 2, be full of water 11 in the water tank 10, heater 102 makes water be heated to 30-40 ℃.Loader 8 can be arranged on one deck polyvinyl acetate ester film 12 on the already heated water surface equably by means of filming.This polyvinyl acetate ester film need be through the condensation process of 30-50 time second, at this moment between in, the ink lay 13 that is formed on these polyvinyl acetate ester film 12 surfaces keeps unlikely and scatters owing to itself flexibility and adhesion strength.

Then, inject a small amount of synthetic toluene to ink lay 13, thereby make the ink lay 13 that swims on the polyvinyl acetate ester film 12 with solid-state form soften by nozzle 9.This moment, it is very intact that the pattern that has on the polyvinyl acetate ester film 12 is held as shown in Figure 2.

Then, the anchor clamps 4 that transmitted by push pedal 5 are come by arm 6 carryings automatically, on the anchor clamps 4 surface of the sole 101 of clamping in water tank 10 coated on ink lay 13 and polyvinyl acetate ester film 12.As shown in Figure 3A, preceding and contact the water surface downwards according to 30 ° incidence angle, sole 101 rolls across on the water surface sole 101 then, shown in Fig. 3 B-3F with its heel region.Make like this and swim on the surface that ink lay 13 on the water 11 and polyvinyl acetate ester film 12 overlayed on sole 101 well.

Can find that by the above the effect of polyvinyl acetate ester film 12 is that water 11 and ink lay 13 can be separated effectively.

After the technical process through Fig. 3 A to 3F, the recess of sole 101, triple curve part and protuberance all obtain uniform coated.

In other words, thus polyvinyl acetate ester film 12 and ink lay 13 are coated by means of buoyancy of water in the surface of sole 101.

In this process, the size of pattern and shape are constant.

If be immersed in sole 101 in the water rather than keep an incidence angle and according to certain coating process, what then resulting ink lay 13 and polyvinyl acetate film coating can not be obtained on the sole 101 is effective on the water surface as according to the method described above sole 101 being rolled across horizontal or vertically.

In other words, if not this method according to the present invention's narration, then polyvinyl acetate ester film 12 and ink lay 13 will be drawn back and be out of shape.Owing to be not to carry out coated, thereby the pattern on the ink lay 13 can be stretched by 1: 1 ratio.

Therefore, the coating process process according to Fig. 3 A to 3F is crucial.

Thereby sole 101 enters rinse bath and polyvinyl acetate ester film 12 is cleaned up stays ink lay 13 in this technological process, and the time that needs is 3 to 5 minutes.Air injection tube dries up the water droplet on the sole 101 needs about 10 seconds, and sole 101 just can be removed moisture fully through hot air dryer 18 more then.

Then, in order to keep ink lay 13 durable, with sole 101 in coating agent injector 19 with clear coat agent Furnisol extract coated 1 to 2 minute again, and dehumidifying 15 to 25 minutes in hot air dryer 21.

Coating by the resulting printing ink 13 of the embodiment of the invention has good wearability, extensibility and coating durability.

As mentioned above, the present invention has narrated the method for automatic coated multicolour pattern on sole surface, and this method improvement production is imitated, and improves the quality of products, and is different from traditional manual coating method fully.
