The term "sander" as the name implies, is the mechanical equipment used in finishing sanding work, and relates to a wide variety of industries, but industry people generally call the sander with an automatic feeding system, and others call the belt sander, the grinder, the polisher, etc.
The existing vertical sander cannot enable the abrasive belt to move up and down during working, so that the utilization area of workers to the abrasive belt is greatly reduced, the workers are not facilitated to adjust the sanding position of the abrasive belt, the sanding effect of the abrasive belt on materials is reduced, and the requirements of people cannot be met.
SUMMERY OF THE UTILITY MODEL
The utility model provides a technical problem provide a vertical drunkenness grinder, the modern design, simple structure can make the abrasive band drunkenness about going on to in increase staff to the usable floor area in abrasive band, and just the staff adjusts the area of polishing in abrasive band, and is comparatively practical, with the problem of proposition in solving above-mentioned background art.
The utility model provides a technical problem adopt following technical scheme to realize:

Furthermore, a first driving motor is fixedly connected to the bottom of the protection box, one end of the first driving motor is rotatably connected with a driving gear, the periphery of the driving gear is meshed with a rack, the other end of the rack is meshed with a driven gear, and the driven gear is fixedly connected with a rotating shaft.
Furthermore, the inside rotation of sand light frame is connected with the pivot, the peripheral rotation of pivot is connected with the abrasive band, sand light frame top fixedly connected with second driving motor, and second driving motor's drive end and pivot fixed connection, the objective table has been put to sand light frame both sides equipartition, and objective table and frame fixed connection.
Furthermore, the first fixed frame and the second fixed frame are respectively connected with the inner side wall of the protective box in a sliding mode through the first limiting sliding plate and the second limiting sliding plate.
Further, fixed axle and first fixed frame fixed connection, the axis of rotation passes through the axle sleeve and is connected with the supporting seat rotation, the threaded rod runs through inside the screw sleeve, and threaded rod and screw sleeve threaded connection, the roller bearing contacts with the cam, first driving motor and second driving motor all pass through wire and electric cabinet electric connection.
Compared with the prior art, the beneficial effects of the utility model are that:
1. can drive the roller bearing through the cam and rotate to can make the roller bearing drive first fixed frame through the fixed axle and reciprocate, so that first fixed frame drives the sand light frame and moves about the guard box is inside, with the increase staff to the utilization area in abrasive band, it is comparatively practical.
2. Through adjusting handle's rotation, can drive the fixed frame of second and reciprocate inside the protective housing through threaded rod and the telescopic combination of screw thread, and through the combination with first fixed frame, highly adjusting at the device top to the sand light frame to can further promote the staff to the area of utilization on abrasive band, comparatively practical.
3. Through the combination of supporting seat and axle sleeve, can carry out good supporting effect to the axis of rotation to promote the bearing capacity of axis of rotation self, make difficult emergence deformation phenomenon when carrying out the work, avoid influencing the normal drunkenness of sand light frame.
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the specific drawings.
As shown in fig. 1-4, in operation, the electric cabinet 27 supplies electricity to the first driving motor 17 and the second driving motor 23, wherein the second driving motor 23 can drive the abrasive belt 22 to rotate at a high speed through the rotating shaft 21, so that the worker can polish the wood, and the first driving motor 17 can drive the driving gear 18 to drive the driven gear 20 to rotate through the rack 19, so that the driven gear 20 can drive the rotating shaft 8 to rotate, so that the rotating shaft 8 can drive the cam 9 to rotate, and the cam 9 contacts with the roller 5, so that the roller 5 can drive the first fixing frame 6 to move up and down through the fixing shaft 4 when the cam 9 rotates, and the movement of the first fixing frame 6 can drive the sanding frame 3 to move up and down inside the protecting box 2, so as to increase the utilization area of the abrasive belt 22 by the worker, it is practical, wherein the second fixing frame 7 can be driven to move up and down in the protection box 2 by the combination of the threaded rod 14 and the threaded sleeve 15 through the rotation of the adjusting hand wheel 16, and the height of the sanding frame 3 at the top of the device can be adjusted by the combination with the first fixing frame 6, so as to further increase the utilization area of the sanding belt 22 by the worker, in addition, the first fixing frame 6 and the second fixing frame 7 can be well limited in position by the combination of the first limiting sliding plate 25 and the second limiting sliding plate 26, so that excessive swing is not easy to occur during moving, the normal operation of the device is prevented from being influenced, and the threaded rod 14 can be connected with the second fixing frame 7 by the combination of the fixing sleeve 12 and the rotating shaft 13, so as to adjust the position of the second fixing frame 7 by the threaded rod 14, through the combination of supporting seat 10 and axle sleeve 9, can carry out good supporting effect to axis of rotation 8 to promote the bearing capacity of axis of rotation 8 self, make difficult emergence deformation phenomenon when carrying out the work, avoid influencing the normal drunkenness of sand light frame 3, the staff of being convenient for places the material through objective table 24, thereby can make the device polish or polish the material.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
