Abstract

The utility model relates to a heating device for a quantitative roller for a roll coater, which comprises a fixing shaft, a roller, a water inlet pipe, and a water outlet pipe, wherein, the roller is sleeved on the fixing shaft and can roll relative to the fixing shaft; the water inlet pipe and the water outlet pipe are arranged in the fixing shaft; the heat transfer medium of the heating device for the quantitative roller adopts hot water. The heating device has the advantages of simple structure and low cost, can eliminate adverse effects caused by low temperature, and has a good practical using effect.

Description

A kind of doctor roll heater

Technical field

The utility model relates to a kind of doctor roll servicing unit, and particularly a kind of coating roller is used the doctor roll heater.

Background technology

Coating roller mainly is to be used for spraying to various materials, at various industries such as building trade, the furniture processing coating roller that all is widely used.The roll coating process of existing coating roller comprises: go up operations such as putty, shaping in advance, secondary reshaping, roller coating.Yet in the lower occasion of temperature, such as in north China, winter, temperature was generally all lower, and material because coating or paint solidify easily, influences actual spraying effect when spraying.Especially when using doctor roll accurately to spray, this influence is particularly evident.

Summary of the invention

The deficiency that the utility model exists to prior art just provides a kind of coating roller to use the doctor roll heater.The described doctor roll heater of the utility model comprises fixed axis, cylinder, water inlet pipe, outlet pipe, and drum sleeve is contained on the fixed axis, and cylinder can roll by the relative fixed axle, and the fixed axis set inside has water inlet pipe and outlet pipe.

The heat transfer medium of described doctor roll heater is a hot water.

The described doctor roll heater of the utility model, compared with prior art, it is simple in structure, and is with low cost, the adverse effect that the fine elimination low temperature of ability brings, practical effect is good.

Fig. 2 is the described doctor roll heater of a utility model half sectional view;

Fig. 3 is the described doctor roll heater of a utility model right view;

Wherein:

1-conveyer belt, 2-material, 3-the first rubber roll, 4-the second rubber roll, 5-the three rubber roll, 5a-fixed axis, 5b-cylinder, 5c-water inlet pipe, 5d-outlet pipe, 6-the four rubber roll.

The specific embodiment

To combine concrete embodiment that the content of the utility model is described below.

As shown in Figure 1, be the described coating roller rubber roll apparatus of the utility model structural representation.The described coating roller rubber roll apparatus of the utility model mainly comprises conveyer belt 1, first rubber roll 3, second rubber roll 4, the 3rd rubber roll 5 and the 4th rubber roll 6.First rubber roll 3, second rubber roll 4, the 3rd rubber roll 5 and the 4th rubber roll 6 can rotate according to direction shown in Figure 1 respectively.

The roll coating process of the described coating roller of the utility model is included as in order: go up four steps such as putty, shaping in advance, roller coating, secondary reshaping.Therefore on the coating roller structure, with the corresponding rubber roll of above four steps be respectively first rubber roll 3, second rubber roll 4, the 3rd rubber roll 5 and the 4th rubber roll 6.

Conveyer belt 1 mainly is to be used for transmitting material 2, can be with material 2 along A to forwarding.First rubber roll 3 is the rubber roll of last putty, goes up putty for material 2 surfaces.Second rubber roll 4 is preparatory shaping rubber roll, and the 3rd rubber roll 5 is the spraying rubber roll.When material 2 passed through the 3rd rubber roll 5, the 3rd rubber roll 5 sprayed for material 2 surfaces.The 4th rubber roll 6 is the secondary reshaping rubber roll, and the material 2 after the spraying carries out secondary reshaping through the 4th rubber roll 6, has guaranteed the surface smoothness and the glossiness of spraying back material 2.

As shown in Figure 2, be the described doctor roll heater of the utility model half sectional view, Fig. 3 is the described doctor roll heater of a utility model right view.In north China, winter, temperature was generally all lower, and coating roller is when accurately spraying, and the spraying effect of the 3rd rubber roll 5 directly is affected.For this reason, the 3rd rubber roll 5 of the utility model is improved to the doctor roll that has heater, realizes the accurate spraying under the low temperature environment.The described doctor roll heater of the utility model comprises fixed axis 5a, cylinder 5b, water inlet pipe 5c, outlet pipe 5d.The fixed axis 5a at doctor roll two ends is fixed on the coating roller.Be set with cylinder 5b on the fixed axis 5a, cylinder 5b can roll by relative fixed axle 5a.Fixed axis 5a set inside has water inlet pipe 5c and outlet pipe 5d.Hot water along B to getting into water inlet pipe 5c, and along C to flowing out from outlet pipe 5d, form a circulation.Under the continuous ringing of hot water, fixed axis 5a and cylinder 5b are reached the effect of preheating by heating gradually like this, have eliminated low temperature to the accurately influence of spraying of doctor roll.

Present embodiment be with hot water as heat transfer medium, also can adopt simultaneously other heat transfer mediums such as water-gas to heat for fixed axis 5a and cylinder 5b, this does not break away from the essence of the utility model.

Claims
