It should be noted that when element is referred to as " being fixedly arranged on " another element, it can be directly on another element Or there may also be element placed in the middle.When an element is considered as " connection " another element, it can be directly connected to To another element or it may be simultaneously present centering elements.Term as used herein " vertical ", " horizontal ", " left side ", " right side " and similar statement are for illustrative purposes only.
Unless otherwise defined, all of technologies and scientific terms used here by the article is with belonging to technical field of the invention The normally understood implication of technical staff is identical.Term used in the description of the invention herein is intended merely to description tool The purpose of the embodiment of body, it is not intended that in the limitation present invention.Term as used herein " and/or " include one or more phases The arbitrary and all combination of the Listed Items of pass.
As shown in Figure 1, the roll shaft 100 in an embodiment, including：Roller core 110, elastic cord breaker 120 and functional layer 130. Elastic cord breaker 120 is set on roller core.Functional layer 130 is set on elastic cord breaker 120.The compression of functional layer 130 is permanent Deformation rate is more than the compression set rate of elastic cord breaker 120.In a specific embodiment, at 70 DEG C, 80% humidity Under conditions of, the compression set rate of elastic cord breaker 120 and functional layer 130 is less than 2%.
The functions such as the required cleaning of roll shaft itself, powder feeding, coating are realized by functional layer, can guarantee that cleaning, powder feeding, painting The functions such as cloth realize effect；Elastomeric cushion material is served as using elastic cord breaker, since the compression of elastomeric cushion material is permanent Deformation rate is small, after a protracted use, still can make it that roll shaft overall deformation is small, so that roll shaft is with longer Service life.Although functional layer compression set rate was both taken full advantage of greatly but had been conducive to the functions such as cleaning, powder feeding, coating The advantages of realizing, although also taking full advantage of elastic cord breaker realizes the bad compression of the functional effects such as cleaning, powder feeding, coating forever The advantages of deformation rate is small long.
In one embodiment, the structure that functional layer 130 is integrally formed.Integrally formed structure causes in functional layer There is no gap, fitting mouth on 130, so that in cleaning, powder feeding, coating process, have effect evenly.Functional layer 130 Specific manufacturing process is drilled and is ground and is molded using a monoblock sponge strip.Certainly, in addition to integrally formed structure, It is bonded or is wrapped in using banding sponge on elastic cord breaker 120 after can also be bent using a bulk of plane sponge. Above-mentioned roll shaft production efficiency is high；Product surface flatness is good, and roughness is small, it is possible to increase sponge scraping property and durability；And Its compact dimensions is convenient to be changed, and is easy to the kind of abundant product.
In one embodiment, the elasticity of elastic cord breaker 120 is more than the elasticity of functional layer 130.Functional layer 130 is typically It is made of the big material of compression set rate, to prevent it from non-reversible deformation occurs, one is provided with below functional layer 130 Layer elastic cord breaker 120.Elastic cord breaker 120 is usually sponge rubber or aerated plastics, its effect is in functional layer 130 When being under pressure, pressure will be absorbed by elastic cord breaker, prevent that functional layer 130 is subject to excessive pressure and occur can not inversion Shape.After pressure disappearance, functional layer 130 and elastic cord breaker 120 can restore to the original state without influencing its function.In a tool In the embodiment of body, elastic cord breaker 120 is polyurethane sponge, ethylene-propylene-diene monomer gelatin sponge or silicone sponge, functional layer are Melamine sponge.
In one embodiment, roll shaft 100 further includes hot melt adhesive layer, which is arranged on roller core 110 and elasticity is delayed Rush between layer 120, can also be arranged between elastic cord breaker 120 and functional layer 130, it can in addition contain in roller core 110 and bullet Hot melt adhesive layer is all set between elastic cord breaker 120 and functional layer 130 between property cushion 120.
In a specific embodiment, the bonding agent of 110 surface of roller core coating is hot-melt adhesive powder.The advantages of hot melt adhesive is Melted after heating, during cooling just the adhering object being in contact with it together, and can heat repeatedly and viscosity remains unchanged.But heat The state of melten gel will also select, and be also to glue puckery, 120 nothing of elastic cord breaker if be entangled in hot melt adhesive film on roller core 110, under normality Method is completely set up.Hot-melt adhesive powder can be used, so that it may solve the problems, such as this well.Before applying hot melt adhesives powder, on roller core 110 One layer of tackifying resin solution is coated in advance with, to make hot-melt adhesive powder be sticked to well on roller core 110.It is then placed at baking oven heating Reason, taking-up are dried in the air cool, rubber powder is solidified and is firmly sticked on roller core 110 after melting, and the surface of adhesive layer is become smooth, easily In the operation for being arranged elastic cord breaker 120 of next step.After elastic cord breaker 120 is put on, baking oven heat treatment is placed again into, is taken out Dry in the air cool, hot melt adhesive just melts, solidifies and roller core 110 and elastic cord breaker 120 firmly stick together again.With original above Reason, can also set hot melt adhesive layer between elastic cord breaker 120 and functional layer 130.
It is appreciated that between roller core 110 and elastic cord breaker 120 and between elastic cord breaker 120 and functional layer 130 Hot melt adhesive layer can be set to use hot melt adhesive layer is set.In one embodiment, elastic cord breaker 120 and functional layer It is interference fit between 130.The internal diameter of functional layer 130 and the outside diameter difference of elastic cord breaker 120 are 0.2mm to 1mm.Roller core 110 Can also be interference fit between elastic cord breaker 120.If roller core 110 and elastic cord breaker 120 and elastic cord breaker All it is interference fit between 120 and functional layer 130, then can be omitted hot melt adhesive layer.Material can be utilized when assembling Elasticity elastic cord breaker 120 and functional layer 130 are assembled.Specifically it is referred to the manufacture method of following roll shafts.
In one embodiment, acted on to give full play to the elastic buffer of elastic cord breaker 120, elastic cord breaker 120 Thickness be more than functional layer 130 thickness.Above-mentioned functional layer 130 be mainly cleaning, powder feeding, coating effect, functional layer 130 Compression set rate is more than the compression set rate of elastic cord breaker 120.Elastic cord breaker 120 mainly plays elastic buffer work With preventing functional layer from irreversible deformation occurs.In a specific embodiment, under conditions of 70 DEG C, 80% humidity, bullet Property cushion 120 and functional layer 130 compression set rate be less than 2%.
The hardness of elastic cord breaker 120 and functional layer 130 does not have special requirement.In one embodiment, elastic buffer The hardness of layer 120 is more than the hardness of functional layer 130.In another embodiment, the hardness of elastic cord breaker 120 is less than functional layer 130 hardness.
