Description
Technical field
The present invention relates to a kind of cloth drying machine, the cloth drying machine of the roller structure of more detailed a kind of cylinder with support garment dryer inside of saying so.
Background technology
In general, cloth drying machine is a kind ofly will be blown into the inside of cylinder by the hot blast that electric heater or gas heater generate, absorb by the moisture in the oven dry thing, and to carried out the device of drying operation by the oven dry thing.Reach being dried the processing mode of the humid air that produces when thing is dried according to absorbing moisture, above-mentioned cloth drying machine is divided into exhaust cloth drying machine and condensation type cloth drying machine substantially.
Illustrate the general shape of cloth drying machine among Fig. 1.Below, will simply describe it.Be provided with in the cloth drying machine: the body 10 that forms outward appearance; The rotatable cylinder 20 that is installed on the inside of above-mentioned body 10; Be used for throwing in by the door 30 of oven dry thing etc. to the inside of dryer.In addition, though detailed icon not, also be provided with lower member in the inside of dryer: its two ends are connected in above-mentioned cylinder, and form the circulation air path of the stream of air circulation; Be installed on the inside of above-mentioned circulation air path, and be used for heater for heating air, and be used for blowing fan of forced circulation air etc.And, under the situation of condensation type cloth drying machine, also including heat exchange department, above-mentioned heat exchange department is used for removing the moisture that contains from the air that cylinder is discharged.
In addition, above-mentioned cylinder 20 will be by the conveyer belt (not shown) from being installed on the motor (not shown) transmission of drive force of the bottom in the body 10, and be rotated.And, sagging for the cylinder that the weight that prevents owing to the weight of washings and cylinder causes, and cylinder can be rotated smoothly, in cloth drying machine, be provided with the device of the bottom that is used for back-up roller, for this reason, in the bottom of cylinder support roller is installed usually.Illustrate the stereogram and the sectional view of above-mentioned support roller among Fig. 2 to Fig. 3.
As shown in Figures 2 and 3, be provided with in the support roller 40 of cylinder: roller shaft 41; Slidably be installed on above-mentioned rollers axle 41, and the roller frame 42 that is rotated; Make by flexible rubber material, and be pasted on the roller outer part 43 of the periphery of above-mentioned rollers framework 42 with back-up roller; Be arranged between above-mentioned rollers framework 42 and the roller shaft 41, and the bearing 44 that above-mentioned rollers framework 42 can be rotated smoothly; At supported on both sides above-mentioned rollers framework 42, and prevent the triangular plug 45 that above-mentioned rollers framework 42 breaks away from from above-mentioned rollers axle 41.
In the support roller 40 of the cloth drying machine of aforesaid prior art, between above-mentioned rollers framework 42 and roller shaft 41, use oilless bearing (oilless bearing), and above-mentioned rollers framework 42 is installed on the above-mentioned rollers axle 41.But, if when the weight of above-mentioned bearings becomes big, the containing immersion oil and oily phenomenon will occur of oilless bearing, and cause the lubrication property variation of roller will cause noise thus, and, the problem of roller breakage will be caused when serious.Particularly, compare with 27 inches dryers, the inner space of 24 inches dryers is narrow and small, and weight is excessive, and the problem of Cun Zaiing will be given prominence to more and be manifested as mentioned above.
And, under the situation of bearing in the prior art, the roller outer part 43 that contacts with cylinder constitutes the shape that mid portion protrudes, it only contacts with bearing in a part of field of the outer part of roller, thereby the stress that will cause acting on roller concentrates on privileged site, and shortened the service life of roller.
Summary of the invention
In order to solve aforesaid problems of the prior art, the object of the present invention is to provide a kind of structure of roller, can bear the bigger weight that acts on the roller of the cylinder that is used to support dryer, and, in the present invention, by widening the scope at the position that roller contacts with cylinder, the concentrated phenomenon that will eliminate stress, and improve the life-span of roller and the reliability of product.
In order to achieve the above object, the cloth drying machine among the present invention, it includes following several sections: body; The rotatable cylinder that is installed on the inside of above-mentioned body; At the roller of the above-mentioned cylinder of lower support of above-mentioned cylinder, wherein, above-mentioned rollers will be installed on the roller shaft by ball bearing.
In cloth drying machine of the present invention, be incorporated on the roller shaft in order to make above-mentioned rollers, will use ball bearing, rather than oilless bearing of the prior art, thereby make the bearing of roller shaft more can bear thermal deformation or the hot wearing and tearing that cause.
And, on the above-mentioned rollers axle, can be formed with the fixture block that is used to install ball bearing, also can be formed with nut in a side of above-mentioned rollers axle and install and use screw thread, and can be formed with screw thread for fixing to the inside of cloth drying machine at the opposite side of above-mentioned rollers axle.
As mentioned above, after roller is installed on the roller shaft, on the nut that a side of roller shaft forms is installed with screw thread, nut is installed, thereby can be made more firm being installed on the above-mentioned rollers axle of roller.
In addition, the contact site that above-mentioned rollers contacts with above-mentioned cylinder is with smooth formation, when roller by the roller frame that is used to insert roller shaft, and the foreign steamer portion that surrounds the outer peripheral face of above-mentioned rollers framework and be installed on the above-mentioned rollers framework is when constituting, and the position that contacts with above-mentioned cylinder on the outer peripheral face of above-mentioned foreign steamer portion is with smooth formation.
As mentioned above,, can make stress obtain disperseing by the position that smooth formation is in contact with one another, and the life-span that can improve roller.
Outer peripheral face at the above-mentioned rollers framework is formed with a plurality of jogs, be formed with a plurality of jogs with above-mentioned jog engagement at the inner peripheral surface of above-mentioned foreign steamer portion, jog by the above-mentioned rollers framework and the jog of foreign steamer portion inner peripheral surface is meshing with each other and combination, can make above-mentioned rollers framework and foreign steamer portion firm carry out combination.And the foreign steamer portion of above-mentioned rollers is preferably made by the rubber material with elastic force.
To provide the roller structure that can bear bigger weight in the cloth drying machine of the present invention, thereby raising will be used for the life-span of the roller of back-up roller, and improve cloth drying machine reliability on the whole.
