Description

[Detailed Description of the Invention] The present invention relates to a novel eraser dust remover. Semicircular protrusions 2, 2' are bored at the lower ends of both sides, and circular recesses 3, 3' are formed at the center of the inner surfaces of the protrusions 2, 2', and a protrusion 2 is formed from the recesses 3, 3'. , 2' groove 4 leading to the lower edge of
.
The shaft end of this suction roll 7 is connected to the side protrusion 2,
The suction roll 7 is removably and rotatably supported at the lower end of the housing 1 by being forcibly inserted into the circular recesses 3 and 3' from the grooves 4 and 4' provided in the housing 1. 1, a partition wall 8 is provided at a horizontal position close to the upper surface of the suction roll 7, and the suction roll 7 is disposed in the center of the partition wall 8.
An inlet 9 for the eraser shavings is cut along the axial direction of the inlet 9.
The upper surface of the mouth edge is obliquely removed to make the mouth edge into a knife blade shape, and the connecting portions with the front and rear surfaces of the casing 1 in the partition wall 8 are made into thin wall portions 10 and 10'. The left and right side edges of the inlet 9 are separated to make both side edges of the inlet 9 elastic, and furthermore, a vertical protrusion 11 is provided on the inner surface of both the left and right side surfaces of the housing 1 from the upper end to the vicinity of the partition wall 8. . . . and separate from this, an n-shaped partition 14 is formed in the housing 1, having an upper surface that becomes the partition surface 12 and both side surfaces that become the sliding surfaces 13 and 13'. The sliding surface 13, 13' of the body 14 is provided with grooves 15 on the outer surface thereof, which fit into the protrusions 11 provided on the inner surface of the housing 1. The partition body 1 is inserted into the center of the housing 1 so as to be slidable in the vertical direction.
The space created between the partition surface 12 of No. 4 and the partition wall 8 is used as a storage place 16 for erasing waste, and the lower end of the sliding surface 13.13' is connected to the separation portions 8, 8 on both sides of the partition wall 8. Then, the scrap protrudes downward and its edge is allowed to come into contact with the circumferential surface of the suction roll 7. Furthermore, a waste outlet 17 is provided in the front wall of the storage space 16, and the accumulated pieces 18 can be freely attached to and removed from the outlet 17. The space above the partition 14 in the housing 1 is used as the insertion part 19 for the eraser opening. When the eraser is rolled and moved, the eraser shavings adhere to the surface of the suction roll 7 and reach the lower surface of the partition wall 8, whereupon one side of the partition wall 8 is pushed up and the eraser swarf enters the inlet 9. However, as the suction roll 7 rotates further, the eraser particles adhering to it come into contact with the cutting edge facing the inlet 9 on the other side of the partition wall 8, and are separated from the surface of the suction roll 7 by the cutting edge. The water is leaked onto the top surface of the partition wall 8.

In this invention, a partition wall is provided at a horizontal position close to the upper surface of the suction roll inside the casing, and the eraser is placed in the center of this partition wall along the axial direction of the suction roll. The inlet is cut out, and the upper surface of the rim of the inlet is obliquely removed so that the rim has a knife-edge shape, and in the partition wall, the connection part with both the front and rear surfaces of the casing is made into a thin wall part. By separating the left and right edges of the partition wall, the edges on both sides of the inflow port can be bounced upward and downward, so that the eraser dust adhering to the suction roll can be removed by pushing one side of the partition wall upwards and into the eraser waste inlet. The material is completely separated from the suction roll by the other cutting edge of the intrusion partition wall, and leakage is ensured to the waste storage area. A protrusion is provided at the lower end of both sides of the shaft, a circular recess is formed on the inner surface of the protrusion, and a groove is formed from the recess to the lower edge of the protrusion, and the outer peripheral surface of the shaft core is covered with a rubber cover. The shaft end of the suction roll is forcibly inserted into the circular recess from the groove, and the suction roll is detachably and rotatably supported at the bottom end of the housing, and a hanging wall-shaped sliding surface is provided on both sides of the bottom surface. The partition body having the above-mentioned sliding surface is fitted into the housing from below so that it joins to the wall surface perpendicular to the inflow port of the shavings, and the lower end of this sliding surface is connected to the cut-off parts on both sides of the partition wall. The suction roll protrudes downward through the casing and can come into contact with the circumferential surface of the suction roll, so when the suction roll is removed from the casing for cleaning etc., the suction roll can be immediately removed from its shaft bearing by pressing down on the partition from above. The suction roll can be removed very easily in a one-touch manner.
