TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a drum surface wiping device for wiping remaining products after treating a product adhered and solidified on a drum surface with a drum flaker or a drum dryer.
[0002]
Problems to be solved by the prior art and the invention
In the case of coagulating or drying and solidifying a multi-component product such as an organic substance using a drum flaker or a drum dryer, or in the case where the product is apt to become a fine powder even with a single component, only a normal scraping device (scraper) can be used to remove oil and the like. May not be completely scraped off or fine powder may remain on the drum surface. In those cases, when the remaining part reaches the liquid supply surface with rotation and is repeatedly supplied, scorching, excessive adhesion, etc. occur, and the blade of the scraper spills due to the impact on the scraper, or due to the remaining oil and fat, Even if the liquid is supplied, the heat conduction is hindered, and the coagulation or the degree of drying deteriorates.
[0003]
For this reason, in the past, the operation was stopped each time and the surface was cleaned with a cloth or a brush, or a brush was arranged in the longitudinal direction of the upper surface of the drum, and the remaining items were wiped off during the operation. As a result, the intended purpose could not be achieved.
[0004]
The present invention has been made in view of the above-mentioned circumstances, and a cleaning material is wound around a cylindrical wiping roll in an exchangeable manner, and is rotated when intermittently moved up and down (contact and separation), and a new wiping is performed. It is an object of the present invention to provide a drum surface wiping apparatus which solves the conventional disadvantage by contacting a part with a drum.
[0005]
[Means for Solving the Problems]
For that purpose, the drum surface wiping device of the present invention is a wiping roll in which a cleaning material for a sheet such as cloth and felt is wound on a cylindrical surface, and both ends of a shaft are pivotally supported.
A pair of take-up units rotatably supporting both ends of the shaft,
A pair of take-up frames that support the take-up unit so that the take-up unit can slide up and down,
A pair of air cylinders mounted on the upper end of this take-up frame,
A gear mounted loosely on the outside close to one of the take-up units of the shaft and a rack attached to a take-up frame at a position where the gear meshes with the gear;
A cam clutch, which is attached by keying to the outside close to the gear and has an outer ring fixed to the gear, and the air cylinder is operated by an electromagnetic valve to move the wiping roll from a position in contact with the surface of the drum. It goes up and down intermittently.
[0006]
Therefore, when the wiping roll moves up and down due to the interim defect, the roll rotates, and the position of the wiping roll that contacts the drum changes.
[0007]
In addition, a rubber lining of a predetermined thickness is provided on the outer periphery of the cylinder of the wiping roll of the present invention, and a groove is provided in the rubber lining in which a round bar is fitted in a longitudinal direction at a position symmetrical with respect to 180 degrees. The wound cleaning material is detachably fixed by a round bar.
[0008]
Therefore, if the cleaning material is wound around a wiping roll and both ends of the cleaning material are fitted into the grooves with a round bar, the cleaning material can be removably attached.
[0009]
In addition, a rubber lining of a predetermined thickness is provided on the outer periphery of the cylinder of the wiping roll of the present invention, and the rubber lining is provided with a narrow groove in a longitudinal direction at a symmetrical position of 180 degrees, and the cleaning wound around the outer periphery. The tip of the material is elastically clamped.
[0010]
Therefore, when the cleaning material is wound on a wiping roll and both ends of the cleaning material are pressed into the narrow grooves by the thin plate-like edge, the cleaning material is detachably fixed by the elasticity of the rubber.
[0011]
Further, the air cylinder of the present invention is configured so that the lift of the wiping roll can be restricted to a predetermined intermediate position.
[0012]
Therefore, it can be set so that the gear of the wiping roll rises to a position where it does not come off the upper end of the rack. Further, the rotation angle of the wiping roll can be adjusted.
[0013]
Further, at the lower ends of the pair of take-up frames of the present invention, adjustable stoppers for regulating the respective lowering positions of the pair of take-up units are provided.
[0014]
Therefore, it is possible to adjust the wiping roll so as to uniformly adhere to the drum surface, and it is possible to set the wiping roll so as not to excessively adhere.
[0015]

This round bar 61b is fitted into one groove as shown in FIG. 5, and the other half of the cloth sheet 61d is wound by one and a half turns. The other end of the cloth sheet 61d is wound around another round bar 61b and pressed into the other groove. Then, the round bar 61b is inserted into both ends of the shaft 61e while inserting the round bars 61b, 61b into the holes 64a, 64b of the bracket 64 shown in FIG. 7 so that the round bar 61b does not rise, and the stop screws 64e, 64e are inserted into the screw holes 64c, 64d (FIG. 3) Screw and fix the round bars 61b, 61b. Thereafter, a screw 64e is screwed into the horizontal screw hole 64f, and the bracket 64 is fixed so as not to come off from both ends of the shaft 61e. One of the holes 64a into which the round bar 61b is inserted is a long hole, whereby the two round bars 61b, 61b are securely pressed against the groove bottom.
A felt sheet may be used in place of the cloth sheet 61d as described above. In addition, a cleaning material such as cloth, felt, sponge, or the like may be wound around the outer periphery of the cylindrical metal without rubber lining, and both ends may be detachably attached with bands.
[0017]
In FIGS. 1, 2, 3, 4 and 8, reference numeral 62 denotes a take-up unit, which is disposed at both ends of the shaft 61e and rotatably supports the wiping roll 61.
[0018]
The pair of take-up units 62, 62 are respectively supported by the take-up frames 63, 63 so as to be slidable in the vertical direction.
Air cylinders 65, 65 having an intermediate stop function are attached to the upper ends of the pair of take-up frames 63, 63, respectively, so that the lift of the wiping roll 61 can be regulated at a predetermined intermediate position by an electromagnetic valve. The gear 61f of the wiping roll 61, which will be described later, rises to a position where it does not come off the upper end of the rack 63a.
[0019]
Adjustable stoppers 63b, 63b are provided at the lower ends of the pair of take-up frames 63, 63 for regulating the lowering position of the take-up units 62, 62. The wipers are adjusted by adjusting the stoppers 63b, 63b. 61 can be set so as to be uniformly adhered to the surface of the drum 10 and not to be excessively adhered.
[0020]
A gear 61f is mounted on the outside of the shaft 61 near the take-up unit 62, and a rack 63a is attached to a take-up frame 63 at a position where the gear 61f meshes with the gear 61f. The outer ring of the cam clutch 61g is fixed to the gear 61f with bolts 61h.
[0021]
Then, while the drum 10 is rotating and the drum flaker shown in FIG. 8 is operating, the drum surface wiping device of the present invention operates as follows.
[0022]
Air pressure is sent to the air cylinders 65 and 65 through an electromagnetic valve, and a wiping roll 61 is pressed against the drum 10 as shown in FIGS. Then, the electromagnetic valve is intermittently operated through an electric circuit (not shown), and the wiping roll 61 is raised to a predetermined position in the middle of the entire strokes of the air cylinders 65 (shown by a two-dot chain line in FIG. 4). At this time, the gear 61f loosely fitted on the shaft meshes with the rack 63a and rotates in the direction opposite to the arrow C in FIG. 1 to rotate the outer ring 61i of the cam clutch 61g, but the cam clutch 61g does not operate. Accordingly, the wiping roll 61 rises to the position indicated by the two-dot chain line in FIG. 4 without rotating. Next, the electromagnetic valve returns to the opposite direction, and the wiping roll 61 descends, and at the same time, the gear 61f rotates in the direction of arrow C, and operates the cam clutch 61g to rotate the wiping roll 61 in the direction of arrow C. 61 rotates by a predetermined angle, and a new point on the circumference contacts the surface of the drum 10.
[0023]
Since the air cylinders 65 and 65 have an intermediate stop function, the stop position when the wiping roll 61 is lifted is adjusted so that the gear 61f does not come off the rack 63a and the lift distance L (FIG. 4) is adjusted. Then, the rotation angle of the wiping roll 61 changes, and the desired position on the wiping roll 61 can be adjusted so as to come into contact with the drum 10.
