Description

Cooling type drying room roller

Technical Field

The utility model relates to the technical field of rollers, in particular to a cooling type drying room roller.

Background

Traditional unpowered cooling roller, rivers can only follow one side spindle nose and flow in, flow from the opposite side again after filling half roller, because the action of gravity, the roller can only have the latter half all the time and can participate in the cooling, and the first half lacks effective cooling, and the weight of meeting greatly increased roller moreover, when the roller is when rotating, rocking of rivers also can increase the unstable factor relatively.

There is therefore a need for a drying room drum that solves the above mentioned problems.

The utility model aims to provide a cooling type drying room roller, which can effectively cool the roller by arranging a cooling jacket in a roller body and forming a cooling flow channel among the roller body, a shaft head and the cooling jacket according to the defects of the prior art.

The purpose of the utility model is realized by the following technical scheme:

a cooling type drying room roller is characterized in that: the cooling jacket comprises a cylindrical hollow inner container and a circular sealing plate connected with the two ends of the hollow inner container, the sealing plate is connected with the inner wall of the cylinder and is uniformly provided with a plurality of notches along the circumferential direction, and a space is reserved between the hollow inner container and the inner wall of the cylinder.

The shaft head is connected with the cylinder body through a connecting ring.

The seal plate is provided with a vent hole, and the vent hole penetrates through the connecting ring and extends out of the barrel body.

The cooling flow channel comprises an internal channel which is communicated in sequence and is provided with a first shaft head, a space which is formed among a first connecting ring in the connecting ring and a first sealing plate in the sealing plate, a gap of the first sealing plate, a space which is formed among a hollow inner container and the inner wall of the barrel body, a gap of a second sealing plate in the sealing plate, a second shaft head in the shaft head, a space which is formed among the second connecting ring in the connecting ring and the second sealing plate, and an internal channel of the second shaft head.

A plurality of supporting ribs are arranged in the hollow inner container.

The utility model has the advantages that: the structure is simple, safe and practical, and the working efficiency is high; the roller can be effectively cooled, and the service life of the roller is prolonged.

FIG. 2 is a schematic view of the structure of the sealing plate in the cooling type drying room roller.

Detailed Description

The features of the present invention and other related features are described in further detail below by way of example in conjunction with the following drawings to facilitate understanding by those skilled in the art:

as shown in the figures 1-2, the marks 1-9 in the figures are respectively represented as a shaft head 1, a cylinder body 2, a cooling jacket 3, a vent hole 4, a connecting ring 5, a sealing plate 6, a hollow inner container 7, a support rib 8 and a notch 9.

Example (b): as shown in fig. 1-2, the present embodiment relates to a cooling type drying room roller, which mainly comprises two shaft heads 1, a barrel 2 and a cooling jacket 3, wherein the two shaft heads 1 are connected with the barrel 2 through two connecting rings 5, the outer ring of the connecting ring 5 is connected with the inner wall of the barrel 2, the shaft heads 1 are installed in the inner ring of the connecting ring 5, and one end of the shaft heads 1 extends out of the barrel 2. In the embodiment, the shaft head 1 adopts a sectional type web structure, and compared with an integral shaft head, the shaft head has enough strength and simultaneously lightens the weight and the processing cost to the maximum extent. In addition, because the diameter of the roller is larger, the common seamless steel tube cannot be manufactured, and the manufacturing process needs to be completed by adopting a plate rolling process, compared with a drying room roller with a small-diameter roller and a large diameter, the contact area between the roller and the cloth can be increased, the cloth can obtain a slower linear speed under the same condition, and the time for full contact is increased, so that a better cooling effect is obtained.

As shown in fig. 1-2, the cooling jacket 3 includes a cylindrical hollow inner container 7, circular sealing plates 6 and support ribs 8, the two sealing plates 6 are respectively connected with two ends of the hollow inner container 7, the sealing plates 6 are connected with the inner wall of the barrel 2, the sealing plates 6 are uniformly provided with six notches 9 along the circumferential direction, and a space is reserved between the hollow inner container 7 and the inner wall of the barrel 1 for guiding the cooling water. The support rib 8 is arranged in the hollow inner container 7 and used for supporting the hollow inner container 7. In addition, the hollow inner container 7 is formed by rolling a steel plate.

As shown in fig. 1-2, a cooling flow channel is formed between the shaft head 1, the cylinder 2 and the cooling jacket 3, the cooling flow channel includes an internal channel of a first shaft head (one of the two shaft heads 1) which is sequentially communicated, a space formed between the first shaft head, a first connecting ring (a connecting ring 5 on the same side of the first shaft head) and a first sealing plate (a sealing plate 6 on the same side of the first shaft head), a gap 9 of the first sealing plate, a space formed between the hollow inner container 7 and the inner wall of the cylinder 2, a gap 9 of a second sealing plate (a sealing plate 6 on the same side of the second shaft head), a space formed between the second shaft head (the other one of the two shaft heads 1), a second connecting ring (a connecting ring 5 on the same side of the second shaft head) and the second three, and an internal channel of the second shaft head. The cooling water passes through the cooling flow channel, so that the cylinder surface of the whole roller can be effectively cooled.

As shown in fig. 1-2, the closing plate 6 is provided with a vent hole 4, and the vent hole 4 passes through the connecting ring 5 and extends to the outside of the cylinder 2. Because the roller needs to be plated with chrome after being finished, the change of temperature can affect the inner side of the cooling jacket 3 and deform, so that the inner container 7 needs to be communicated with the outside to balance the internal air pressure and the external air pressure.

In summary, in the embodiment, the roller cooling is mainly aimed at protecting the bearings at the two ends except for partial process consideration. Traditional unpowered cooling roller is similar to this, but do not have the intermediate layer, rivers can only follow one side spindle nose and flow in, flow from the opposite side again after filling half roller, this kind of simple structure, the preparation is convenient but because gravity, the roller can only have the latter half all the time and can participate in the cooling, and the first half lacks effective cooling, and the weight of meeting greatly increased roller, when the roller is when rotating, rocking of rivers also can increase the unstable factor relatively, this kind of a series of problems of avoiding that the baking house cooling roller of this kind of new construction can be fine.

Although the conception and the embodiments of the present invention have been described in detail with reference to the drawings, those skilled in the art will recognize that various changes and modifications can be made therein without departing from the scope of the appended claims, and therefore, they are not to be considered repeated herein.
