Description

[0001] The present invention relates to a heating roller of a fabricator,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fabricating machine, and more particularly, to a heating roller of a fabricating machine that performs additional processing on a fabric by continuously transferring heat to the fabric surface.

As is well known, textile woven fabrics are processed through various additional processes after weaving to obtain finished fabrics.

Hereinafter, the present invention will be described by taking as an example a heat-transfer unit among various types of heat-generating rollers used for producing a fabric.

Known heat-transfer machines heat-press and transfer various patterns such as characters, symbols, and graphics onto the surface of a fabric or paper using a thermal transfer paper, and improve the productivity by improving the heat drum.

Conventional drum type heaters are composed of a drum heater, a deceleration motor, a flat belt, and a plurality of driven rollers.

The drum heater is equipped with a heater and a temperature sensor inside, and the heat of the heater heated to a proper temperature is transferred to the surface. When the heat is applied to the transfer sheet while rotating around the axis of the inner center, the pattern of the transfer sheet is transferred to the fabric. The deceleration motor rotates the drum heater by connecting the chain to the shaft of the drum heater. The plurality of driven rollers are installed parallel to the drum heater so as to have a somewhat height difference from the upper and lower portions of the drum heater.

The flat belt is provided on the outer surface of the plurality of driven rollers so as to be staggered, and a part of the area is engaged with a part of the drum heater by the rotation of the driven roller, and the remaining area runs in a planar manner.

In the transferring process using the conventional drum type heat exchanger having such a structure, the drum heater, which is kept in constant temperature by the internal temperature sensor, is rotated by the decelerating motor, the thermal transfer paper and the fabric are put into the drum heater by the flat belt, The fabric is thermally pressed by the drum heater and the flat belt, whereby the pattern printed on the transfer sheet is transferred to the fabric, and the transfer sheet and the transferred fabric are discharged to the outside of the drum heater

Since the temperature sensor is installed inside the drum heater, the temperature measured inside the drum heater is a temperature difference between the actual temperature transferred by the time transferred to the surface of the drum heater and the temperature difference is about ± 5 degrees I go.

This temperature deviation has a problem in that the colors of the transferred patterns are not uniform.

In order to solve the above problems, the applicant of the present invention has proposed a heating roller as disclosed in Korean Patent Laid-Open Nos. 2015-0118450 and 2015-0073836.

In order to solve the problems of the prior art, the above-mentioned Laid-Open Patent Application No. 2015-0118450 discloses a method for improving the thermal efficiency by increasing the heat transfer and circulation space for the transfer of work on the fabric, A plurality of injection holes are formed on the outer circumferential surfaces of the cylindrical drum on both sides at regular intervals so as to improve the circumferential direction of the inner drum, A pair of flow drums are provided at the ends of the inner drum so as to be coupled to the outer circumferential surface of the inner drum, and the injection pipe and the flow drum are disposed in the inner drum, And a roller which is connected to both ends of the drum, and passes through the inside of the drum in the longitudinal direction, And a supply pipe connected to a supply side of the supply pipe to supply the supply pipe to the injection pipe in such a manner as to divide the heat medium oil into the supply pipe and the supply pipe, And a discharge portion connected to the discharge hole of the inner drum communicating with the space and collecting the heat medium oil and discharging the heat medium to the discharge side of the discharge pipe. The heat medium oil heated at a high temperature is supplied to the entire area of the roller at the same time, .

On the other hand, Japanese Patent Application Laid-Open No. 2015-0073836 discloses that a plurality of discharge holes are formed in the middle of the cylindrical drum in the longitudinal direction thereof along the circumference of the drum, and a plurality of discharge holes Each of the three injection pipes thus formed

And the heat medium oil is divided into three equal parts at one end of the drum and divided into two equal parts by dividing each divided heat medium oil into two equal parts, And a discharge portion for discharging the divided heat medium oil from the other end of the drum to the discharge hole is connected to the discharge hole in an arrangement of 60 degrees along the inner circumference of the drum. A sealing member for closing the spacing space between the injection pipes is formed, and a roller is formed to form a thermal medium oil flow space (S) between the thermal medium oil flowing space (S) and the heat medium oil heated to a high temperature, And the heat medium oil that has been heat-transferred is discharged without leaving, and the transfer quality is fixed, so that the quality is improved. It has been made to key.

Even if the above-mentioned prior application filed by the present applicant has a relatively large diameter and a long axial length, there is a disadvantage in that the heat distribution is partially deviated on the entire surface of the roller, It is found that the temperature difference generated during the circulation of the heat medium is directly transferred to the drum due to the structure in which the heat conduction is directly applied to the drum while being introduced into and recovered from the drum.

The present invention has been made in order to complement such a pre-filed invention.

Attention is now directed to FIGS. 1 to 4.

The present invention relates to a drum type washing machine comprising an outer drum 1 and an inner drum 2 provided to be spaced apart from each other in the outer drum so as to be circulated in the inner and outer drum compartment 3 by an external heat source H, (3) between the inner and outer drums (2, 1). The heat roller (1) has a heat medium flow path and is closed at both ends of the inner and outer drums with a flange constituting a rotating shaft (4) And the inside of the compartment is filled with a pipeline cell unit 6 for introducing and discharging the heat medium and is heated by the external heat source H and pressurized by the pump P to the pipeline cell unit 6 And a second heating medium (M2) is sealed in the outer drum (2, 1) compartment (3), the heating medium being heated and transferred from the first heating medium, Is transferred from the first thermal medium (M1) to the second thermal medium (M2) The heating roller 10 is configured to be heated by the indirect heat to form the heating roller of the fabricator.

The pipeline cell unit 6 for transferring the first heating medium M1 in the compartment 3 of the heating roller 10 is constructed such that the pipes of the drums 1 and 2 extend long in the longitudinal direction, And a plurality of pipeline cell units 6 are built in the compartments 3, as shown in FIG.

The optimum number of the pipeline cell units 6 is determined considering the diameter and the length of the drum. In addition, the time required for the heat medium circulating in the pipe to stay in the pipe, the temperature rise temperature of the heat medium, Can be considered.

Therefore, consideration is given to determining the number of pipeline cell units according to the case where the diameter of the drum is large and the axial length of the drum is long, that is, the case where the diameter of the drum is small or the axial length of the drum is short.

The pipeline cell unit 6 for transferring the first thermal medium M1 in the compartment 3 of the heating roller 10 is formed by annularly dividing the circumference of the drums 1 and 2, .

And may be between 4 and 8 depending on the diameter and axial length of the drum constituting the heating roller 10.

The volume of the second heating medium (M2) sealingly engaging in the compartment (3) of the heating roller (10) is less than the internal effective volume of the compartment (3).

The volume of the second heating medium M2 is equal to or less than the effective volume of the compartment 3 when the second heating medium M2 is heated and expanded by the first heating medium M1. .

A first heat medium M1 is circulated through both ends of the rotary shaft 4 to circulate the first heat medium M1 to the plurality of pipeline cell units 6 through the distribution port 5a and the pipeline cell unit 6, (5b) for collecting the molten metal (M1) is formed, and the end of the pipe (62) of the pipeline cell unit (6) is connected to the distribution port and the recovery port so as to communicate with each other.

The pipeline cell unit 6 is formed by bending the pipe 62 in a zigzag structure having an equal interval.

The distribution port 5a and the recovery port 5b may have a closed one end and an open cylindrical end and may be connected to the outer circumference of the cylinder by a pipe 62 connected to the pipeline cell unit 6, .

The inlet and outlet ends of the pipes 62 are separately welded to the connection holes of the distribution port 5a and the recovery port 5b to constitute the distribution and inflow of the first thermal medium M1 and the collection and discharge of the first thermal medium M1.

The pipe line cell unit 6 according to the present invention can be modified as shown in FIG. 6, in which a pipe 62 formed by bending in the zigzag structure described above and a closed empty pipe 64 are provided in a space between adjacent pipes .

The present invention is also characterized in that the second thermal medium M2 flows between the pipe 62 made of the zigzag bending pipe 62 or the pipe 62 and the hollow pipe 64 so that the first thermal medium M1 circulates, A gap is created so as to be possible.

A plurality of ribs are welded to the long extended portion between the pipes 62 or between the pipe 62 and the hollow pipe 64 to secure the respective pipes of the entire pipeline cell unit to a rigid Thereby constituting a fastening.

The effective volume of the compartment (3) of the present invention refers to the volume excluding the elements occupying the compartment internal volume including all the elements internally coupled to the compartment, namely, the pipe (62) and the empty pipe (64).

The operation of the present invention having the above-described structure will be described in more detail.

The present invention is characterized in that a heating medium heated by an external heat source H is heated by a drum P as a pump P, It is usefully applied to a heating roller that carries out the necessary additional processing.

According to the present invention, the first heating medium (M1) heated by the external heat source (H) is conveyed through the pipeline to the inside of the compartment (3) of the external drum (2, 1).

The first heating medium M1 is supplied to the distribution port 5a by the pressure of the pump P and is supplied through the inlet ends of the plurality of pipes 62 communicating with the distribution port, 6) through the pipe.

The first thermal medium M1 subjected to the thermal conduction is collected by the recovery port 5b which is connected to the discharge end of each pipeline cell unit 6 and is recycled while being recovered by the pump P to achieve thermal conduction.

The latent heat of the first thermal medium M1 is transferred to the second thermal medium M2 enclosed in the compartment 3 so that the second thermal medium M2 is heated and the heat of the medium is transferred to the outer drum 1 So that it acts as the heating roller 10.

The second heating medium M2 flows into the gap between the pipes 62 by the rotation drive (not shown) of the heating roller 10 to smooth the heat distribution, The temperature distribution on the surface can be made uniform.

On the other hand, the volume of the second heating medium (M2) which is heated by the conductive heat of the first heating medium (M1) is set such that the volume after the thermal expansion at least takes into account the expansion of the effective medium volume So as to prevent damage to the heating roller of the drum due to expansion and contraction.

In addition, when the space between the zigzag arranged pipes 62 of the pipeline cell unit 6 installed in the compartment 3 is large, the amount of the second thermal medium M2 to be sealed becomes large, The heating time may be increased. In this case, the volume of the compartment is reduced so as to reduce the amount thereof by constituting a closed empty pipe 64 between the pipes 62, so that the heat efficiency is increased.

According to such a structure, the number of the built-in units according to the axial extension of the heating roller 10 and the diameter of the circumferential diameter of the heating roller 10 is 4 to 8 And the number will ultimately be determined in light of the heat transfer rate.

Of course, in the case of incorporating a plurality of pipeline cell units, if the circumference of the drum is equally divided and one pipeline cell unit is manufactured in accordance with the divided circumferential angle, It will be readily understood that the invention can be practiced evenly.

As a matter of reference, the heat transfer efficiency may be lowered when the number of pipes of the unit pipeline cell unit is small on the basis of the drum having the same diameter, and in many cases, the structure of the heat medium flow- . &Lt; / RTI >
