Description
BACKGROUND OF INVENTION
Field of Invention
[0001] The present invention relates to an adjustment structure of
upward-opening abrasive cloth rollers, and more particularly to an
adjustment structure capable of adjusting the roller and the
machine panel.
Description of Related Art
[0002] Currently, the conventional abrasive cloth roller machine
comprises a machine with a roller having an abrasive cloth layer,
and a conveyor belt located under the roller. By adjusting the
distance between the conveyor belt and the roller, the grinding
depth of the sheet is controlled. However, the above structure
actually has the following disadvantages:
[0003] (1) The grinding depth of the sheet is controlled by the
distance between the conveyor belt and the roller. To change the
distance, the entire conveyor belts needs to be adjusted and it is
also necessary to maintain to the level of the conveyor belt, so it
is difficult to adjust it finely.
[0004] (2) It is known that the abrasive cloth roller machine can
only grind plate with parallel surfaces. If the production needs to
grind a slope on the plate, it is difficult to achieve and maintain
the same reproducibility.
[0005] Therefore, it is desirable to provide an adjustment
structure of upward-opening abrasive cloth rollers to mitigate
and/or obviate the aforementioned problems.
SUMMARY OF INVENTION
[0006] An objective of present invention is to provide an
adjustment structure of upward-opening abrasive cloth rollers,
which is capable of improving the above-mention problems.
[0007] In order to achieve the above mentioned objective, an
upward-opening abrasive cloth roller has a roller below the
abrasive cloth. The system has: a support frame mounted on a
machine, a roller is disposed on the support frame, a hollow panel
is mounted on the machine, and the first side of the panel is
pivotally connected to the machine. The two ends of the support
frame are respectively provided with individual height adjustment
structures, and a panel level adjustment structure is mounted on
the machine on below the second side of the panel. With the above
two adjustment structures to adjust the level of the roller and the
panel, the plate can be easily adjusted for different grinding
depths and angles.
[0008] Other objects, advantages, and novel features of invention
will become more apparent from the following detailed description
when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
[0017] First, please refer to FIGS. 1-8. An adjustment structure of
upward-opening abrasive cloth rollers comprises: a supporting frame
20 mounted on a machine 10, a first wedge block 231 and a second
wedge block 232, a roller 30, a first positioning member 310 and a
second positioning member 320, a first returning spring 261 and a
second returning spring 262, a first screw 271 and a second screw
272, a first positioning block 41 and a second positioning block
42, and a first positioning spring 421 and a second positioning
spring 422. The supporting frame 20 has a first slot 211 connected
to a first through hole 221 at one end, and a second slot 212
connected to a second through hole 222 at the other end. The first
wedge block 231 and a second wedge block 232 respectively have a
first containment space 241 connected to a first screw hole 251 and
a second containment space 242 connected to a second screw hole 252
and are disposed in the first and second slots 211, 212
respectively. The roller 30 has a first bearing 31 and a second
bearing 32 at both ends. The first positioning member 310 and the
second positioning member 320 are disposed at the ends of the first
and second bearings 31, 32 and respectively in the first and second
slots 211, 212. The first returning spring 261 and the second
returning spring 262, placed in the first and second containment
spaces 241, 242. The first screw 271 passes through the first
through hole 221, the first returning spring 261 and the first
screw hole 251 and is screwed with the first wedge block 231. The
second screw 272 passes through the second through hole 222, the
second returning spring 262 and the second screw hole 252, and is
screwed with the second wedge block 232. The first positioning
block 41 is disposed above the first slot 211, and a first
positioning groove 411 is provided at the middle of the first
positioning block 41. The first positioning spring 421 is disposed
in the first positioning groove 411 and pushes against the first
positioning member 310. The second positioning block 42 is disposed
above the second slot 212, and a second positioning groove 412 is
provided with in the middle of the second positioning block 42. The
second positioning spring 422 is disposed in the second positioning
groove 412 and pushes against the second positioning member
320.
[0018] Please refer to FIGS. 6 and 7 again. When the first and
second screw 271, 272 are rotated clockwise, the first and second
returning spring 261, 262 maintain the outward stretching tension,
to move the first and second wedge blocks 231, 232 toward to the
axial position of the roller 10 and lift the first and second
positioning members 310, 320. In other words, when the first screw
271 is rotated clockwise, the end of the roller 10 at the same side
is adjusted slightly higher; when the first screw 271 is rotated
counter-clockwise, the first wedge block 231 is moved to the left
and the end of the roller 10 at the side is slightly lowered.
[0019] Furthermore, wherein two sides of each of the first and
second positioning members 310, 320 make contact with the first and
second slots 211, 212, and both of the first and second positioning
members 310, 320 have two parallel vertical sides and two curved
ends, which ensures the roller to have only vertical movements.
[0020] Moreover, the first and second positioning springs 421, 422
also always maintain the outward stretching tension, so that the
roller 10 can maintain precise positioning and allow
micro-adjustment. In addition, the first and second positioning
blocks 41 and 42 may have more than one positioning groove for
accommodating more than one positioning spring.
[0021] Please refer to FIGS. 5 and 8. The adjustment structure
further comprises: a hollow panel 11, a third through hole, a
C-type fixing member 50, an adjustment disk 51, a screw 52 and a
supporting member 53. A first end 111 of the panel 11 is pivoted
onto the machine 10 and a second end 112 of the panel 11 is capable
of rotation. A third through hole 101 is disposed at a sidewall of
the machine 10 below the second end 112 of the panel 11. The C-type
fixing member 50 is disposed inside the sidewall of the machine 10
and has an upper through aperture 501 and a lower through aperture
502. The adjustment disk 51 is disposed in the C-type fixing member
50 and partially exposed from the third through hole 101 and has an
inner thread. The screw 52 passes through the upper through
aperture 501, the adjustment disk 51, the lower through aperture
502, and engages with the adjustment disk 51. The supporting member
53 secured above the screw 52 and supporting the second end 112 of
the panel 11.
[0022] When the adjustment disk 51 is rotated clockwise, the screw
52 and he supporting member 53 move upward to lift the second end
112 of the panel 11.
[0023] Moreover, in order to secure the supporting member, a fourth
through hole 102 is disposed above the third through hole 101, the
supporting member has a fifth through hole 531, and a screw 54
passes through the fifth through hole 531 and the fourth through
hole 102 and engages with a packing screw 55.
[0024] According to the above structure, the following advantages
can be obtained:
[0025] (1) Since the abrasive cloth roller to upward-open, in order
to adjust the grinding depth, it only needs to adjust the level of
the hollow panel 11 to control the exposed height of the roller 10,
and the more of the roller 10 is exposed, the more polished the
plate, the more of the grinding depth can be achieved. The effect
of changing the inclination angle of the hollow panel 11 can easily
change the polishing depth.
[0026] (2) In the present invention, the level of the roller 10 can
be easily adjusted by rotating the first and the second screws 271,
272, due to the production needs or due to uneven with the machine
or floor.
[0027] Although the present invention has been explained in
relation to its preferred embodiment, it is to be understood that
many other possible modifications and variations can be made
without departing from the spirit and scope of invention as
hereinafter claimed.
