Abstract

The utility model relates to a heating and draining structure of a corrugated roller, which comprises a main body, wherein the main body includes a shaft head and a cylinder connected with the shaft head; a linear groove and an annular groove connected with the linear groove are formed on the inner wall of the cylinder, the annular groove is formed on the front part of the inner wall of the cylinder; and one end of a siphon is in contact with the annular groove. The heating and draining structure can solve the problem on the quality of paper boards caused by the low thermal transmission efficiency and roller deformation caused by condensed water.

Description

Corrugation roller heating discharge structure

Technical field

The utility model relates to a kind of corrugation roller, relates in particular to the heating discharge structure of this corrugation roller.

Background technology

The corrugation roller all must just can make cardboard through forming later the corrugation shape by heating, corrugation roller of the prior art is generally with electrical heating, oil heating, three kinds of forms of Steam Heating (with reference to GB/T1447.1-2000 corrugation roller standard 4.2), and wherein Steam Heating is low because of cost, thermal source stable, security performance is good is commonly the client for a long time and accepts use.

As seen from Figure 1: the Steam Heating of corrugation roller is by with steam 1 by spindle nose 5 draw roll tube inner chambers 6 from inside to outside, roll body 2 is conducted heat, the corrugation roller is when operation, body paper and corrugation roller carry out the Continuous Heat exchange, become condensed water after the steam release heat, stockpile in the roll body inner chamber, by steam pressure condensed water is got rid of continuously through siphon pipe 4 again; And siphon pipe is because design feature must keep certain distance with corrugation roller inwall, and exist in the position of whole roll body inner chamber with a point, can't up hill and dale condensed water be discharged roll body immediately with the variety of issues such as difficulty that precision, accuracy of manufacture control are installed again, so form one deck liquid moisture film at inwall.

Problem with regard to existing like this, the one, can't thoroughly in time get rid of condensed water, hinder steam heat transfer efficiency, make the corrugation roller that sufficiently stable temperature can not be arranged, the cardboard fluting of producing is not good; The 2nd, when the corrugation roller shuts down; because of the distance of siphon pipe inwall can't drain condensed water; there is bottom, whole roller chamber in condensed water; form the corrugation roller top and the bottom temperature difference and bending; produce one section cardboard waste product when producing thereby cause the corrugation roller to turn round again, be heated evenly gradually, could produce normal after recovery is eliminated and is out of shape up to whole corrugation roller roll body; because the shutdown frequency of carton factory is quite frequent, causes its accumulating losses very big.

Summary of the invention

The utility model technical issues that need to address have provided a kind of corrugation roller heating discharge structure, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The utility model comprises: body; Body comprises: spindle nose and the cylindrical shell that joins with spindle nose; On described cylinder lumen wall, be provided with straight-line groove and link to each other with straight-line groove, at the annular groove of cylinder lumen wall front portion; A siphonal end contacts with annular groove.

Compared with prior art, the beneficial effects of the utility model are: solved the heat transfer efficiency and the roll body that are caused by condensed water and be out of shape the board product quality problems that cause.

Description of drawings

Fig. 2 is the utility model structural representation.

Fig. 3 is the view of A-A among Fig. 2.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

By Fig. 2, Fig. 3 as seen: the utility model comprises: body 10; Body 10 comprises: spindle nose 103 and the cylindrical shell 105 that joins with spindle nose 103, on described cylindrical shell 105 internal chamber walls, be provided with straight-

line groove

107 and 107 that link to each other with straight-line groove, at the annular groove 106 of cylindrical shell 105 internal chamber wall front portions; One end of a siphon pipe 108 contacts with annular groove 106.

The utility model steam 101 enters cylindrical shell 105 inner chambers along spindle nose 103 ducts roll body is heated, the condensed water that forms is back to annular groove 106 through straight-line groove 107, discharge by siphon pipe 108 again, finish condensed water is discharged in heating that whole steam enters the roller inner chamber again through siphon pipe overall process.

Design of the present utility model has changed the condensed water that traditional corrugation roller adds thermosetting and has been adsorbed on the simple structure that the roll body inner chamber is discharged by siphon pipe more naturally, but by on the roll body inwall, straight-line groove being set, make the corrugation roller in the running, because groove makes condensed water can't form the moisture film of thermal resistance at inwall, thereby improved heat transfer efficiency, increased heat exchange area simultaneously; By steam condensed water is back to annular groove by straight-line groove again, thoroughly condensed water is discharged roll body by siphon pipe again, from and solved because of condensed water and stockpiled the problem that in whole roll body, causes stopped status lower corrugated roller distortion.

Claims

1. a corrugation roller heating discharge structure comprises: body; Body comprises: spindle nose and the cylindrical shell that joins with spindle nose; It is characterized in that: on described cylinder lumen wall, be provided with straight-line groove and link to each other with straight-line groove, at the annular groove of cylinder lumen wall front portion; A siphonal end contacts with annular groove.
