Abstract

The invention discloses a manufacture method for drying rotary drum, belonging to its structure concerned of a garment drying machine. Its structure is formed by several divided parts to be assembled into a rotary drum shaped in a barrel. The rotary drum is made up from a toughening resin material. Thus, during drying process, noises from the inside things impacting to the inner surface of the rotary drum will be declined, and the damage to the drum will be effectively avoided.

Description

The manufacture method of drying roller

Technical field

The invention relates to the structure of cloth drying machine rotary container, the manufacture method of more detailed a kind of drying roller of saying so.

Background technology

Usually, cloth drying machine heats inhaled air from the outside with heater, the warm-air supply of heating to taking in, to the machine of being fulfiled dry task by the oven dry thing by in the drying roller of oven dry thing.

As shown in Figure 1, in the dry run of cloth drying machine, drying roller (1) is rotated, the center of circle, drying roller (1) inner peripheral surface upper edge direction, by certain interval hoisting mechanism (2) is set, being lifted to the method that certain altitude falls again by the oven dry thing, make by the oven dry thing to be emerging in equably under the hot blast, be used for promoting its dry run.

Simultaneously, drying roller (1) mainly forms with steel, and the hoisting mechanism (2) that drying roller (1) inner peripheral surface is provided with is after plastic cement material is made respectively, is attached to drying roller (1) inner peripheral surface with screw fashion.

But there are the following problems for the drying roller of conventional art (1) aborning:

The first, in order to make the cast tube equipment of drying roller (1) needs manufacturing cast tube in the past, so there is the bigger problem of this equipment investment.

The second, drying roller (1) needs a lot of manufacturing processes in order to produce in the past, so the problem points that exists production efficiency to reduce thereupon.

The 3rd, drying roller (1) needs the process complexity and loaded down with trivial details manufacturing technique, the problem points that exists the defect ware rate to raise in order to produce in the past.

The 4th, drying roller (1) was to be that material forms with steel in the past, impacted and took place noise so brought at drying roller (1) inner peripheral surface by the oven dry thing, or the damage of drying roller (1) takes place.

Summary of the invention

The objective of the invention is in order to solve the problem of above-mentioned conventional art, and a kind of manufacture method of drying roller is provided.

In order to reach as above purpose, the manufacture method of drying roller, the drying roller inner peripheral surface that is included in the drum shape is along center of circle direction, the a plurality of hoisting mechanisms that possess at regular intervals, it is characterized in that drying roller is to be integral with shape and the hoisting mechanism of cutting apart along its center of circle direction, become the cylinder of a drum shape after the drying roller assembling of a plurality of segmented shape.

As above the present invention of Gou Chenging, the drying roller and the hoisting mechanism that inject a plurality of segmented shape from mould are integrally formed, after the simple assembling, manufacture the drying roller of drum shape.It is simple easily to have manufacturing technique, the effect that the equipment investment of making drying roller is successively decreased, production efficiency improves, the defect ware rate reduces.Drying roller because of segmented shape adopts the tempering resin material to make again, in dry run, when lowering by oven dry thing and drying roller inner peripheral surface impact noise, the effect that prevents the drying roller damage is arranged.

Fig. 3 is the drying roller assembling back status architecture schematic diagram of a plurality of segmented shape among Fig. 2.

Fig. 4 is that the drying roller of a plurality of segmented shape of Fig. 3 is otherwise assembled back status architecture schematic diagram.

The symbol description of major part among the figure:

10: the drying roller 20 of segmented shape: hoisting mechanism.

The specific embodiment

Followingly be elaborated for the present invention with reference to drawings and Examples.

Fig. 2 is the preceding status architecture schematic diagram of drying roller assembling of a plurality of segmented shape among the present invention, Fig. 3 is the drying roller assembling back status architecture schematic diagram of a plurality of segmented shape among Fig. 2, and Fig. 4 is that the drying roller of a plurality of segmented shape of Fig. 3 is otherwise assembled back status architecture schematic diagram.

As shown in Figure 2, side face is integrally formed within it for the hoisting mechanism of drying roller (20) among the present invention, and its front side end face roughly becomes arc, the drying roller of a plurality of segmented shape (10) is assembled and is constituted.

The drying roller of segmented shape (10) roughly is divided into trisection to the drying roller of drum shape, and each hoisting mechanism (20) is the side face form that forms as one within it.

Here, the drying roller of segmented shape (10) injection moulding in isomorphic mould, and, be to form with the tempering resin material.

As mentioned above, the drying roller of a plurality of segmented shape of manufacturing (10) is assembled the drying roller that just can produce a drum shape; As shown in Figure 3, the drying roller of three segmented shape is assembled into the drying roller of a drum shape.

The drying roller of above-mentioned segmented shape (10) interconnects with screw fashion.

Simultaneously, the drying roller of segmented shape (10) mode of assembling mutually also may be as shown in Figure 4, interconnects with the mode of linking up with.

And though not shown, the drying roller of above-mentioned segmented shape (10) is assembling mutually, also may connect with the mode of welding.

As mentioned above, the drying roller (10) that is suitable for the segmented shape of manufacture method of the present invention is in possessing isomorphic mould, manufacture one with injection moulding mode and hoisting mechanism (20), as mentioned above, owing to make the drying roller (10) of a plurality of segmented shape, simply connect assembling again and manufacture the drying roller of drum shape, so the manufacturing equipment expense is successively decreased, also can produce in a large number,, reduce the defect ware rate again because of manufacturing technique is simple.

And the drying roller of segmented shape (10) material is the tempering resin, in drying course, have that irony is decorated and the clothing class of button etc. by oven dry thing and drying roller collision, or pull and the noise of generation can hang down and subtracts, also can prevent the damage of drying roller.

In addition, in the present invention, when the drying roller of a plurality of segmented shape (10) was assembled into the drying roller of drum shape, the situation that forms 3 hoisting mechanisms (20) at the drying roller inner peripheral surface of drum shape illustrated.When if the drying roller inner peripheral surface of drum shape forms 4 hoisting mechanisms (20), in order to make the drying roller of drum shape, make the drying roller of segmented shape by the quartering, or binary form is made the drying roller of segmented shape, thereafter assembling also must reach effect of the present invention equally.

At this moment, on the drying roller of drum shape, the drying roller of quartering segmented shape is for forming a hoisting mechanism of one, and the drying roller of bisection segmented shape is comparison successes for two hoisting mechanisms that form one.
