Detailed Description

The present application is described in further detail below with reference to figures 1-6.

The embodiment of the application discloses a grinder for polishing plates. Referring to fig. 1, the sander comprises a frame 7, a horizontal conveying platform 6 is arranged in the frame 7, a contact sand rack 1 and a pressing sand rack 8 are sequentially arranged above the conveying platform 6 and in the frame 7 along the conveying direction of plates, a conveying belt 61 is further arranged on the conveying platform 6, the conveying belt 61 conveys the plates into the frame 7, and the plates are sequentially polished by the contact sand rack 1 and the pressing sand rack 8.

Referring to fig. 2, the contact sand frame 1 comprises a contact roller 11 and a tension roller 12 located above the contact roller 11, and a ring of abrasive belt 13 is provided between the contact roller 11 and the tension roller 12. Wherein, contact roller 11 is used for compressing tightly panel and carrying out dull polish processing to panel, and tensioning roller 12 is used for adjusting the tensioning degree of abrasive band 13, and specifically, the tensioning degree of abrasive band 13 can be adjusted to the distance between adjustment tensioning roller 12 and contact roller 11.

Referring to fig. 3 and 4, the contact roller 11 includes a cylindrical roller body 2, and the roller body 2 is provided with support short rods 21 at both ends in the axial direction thereof, and the support short rods 21 are used to support the roller body 2. The circumference surface cover of roll body 2 is equipped with a plurality of rolling rings 3, and each rolling ring 3's external diameter is the same, and a plurality of rolling rings 3 set up side by side along the axial of roll body 2. Because in the current production process, when using contact roller 11 to compress tightly panel and polish panel, contact roller 11 can compress tightly panel, and contact roller 11 can receive the bellied influence in panel surface for the wearing and tearing of different degrees appear in contact roller 11's circumference surface, contact roller 11's diameter is all around all inequality along its axial, and contact roller 11 who receives wearing and tearing can make the panel surface appear the condition of polishing inadequately when polishing panel. Consequently, this scheme has set up a plurality of rolling rings 3 on with roll body 2, and the rolling ring 3 to wearing and tearing is dismantled and is changed, guarantees that roll body 2's circumference surface diameter everywhere is the same to guarantee the quality that panel polished.

Referring to fig. 4 and 5, the circumferential outer surface of the roller body 2 is provided with a plurality of sliding grooves 22, each sliding groove 22 extends to the other end along the axial end of the roller body 2, and each sliding groove 22 is spirally arranged along the circumferential outer surface of the roller body 2. The surface of the inner ring 31, which is attached to the outer surface of the roller body 2, of each rolling ring 3 is provided with a plurality of sliding strips 312. During installation, the sliding strips 312 on each rolling ring 3 correspond to the sliding grooves 22 one by one, the rolling rings 3 spirally slide from one end of the roller body 2 to the other end along the sliding grooves 22, and the next rolling ring 3 also slides into the roller body 2 along the sliding grooves 22 and abuts against the previous rolling ring 3.

Referring to fig. 5, the outer surfaces of the two axial ends of the roller body 2 are provided with external threads 23, the two ends of the roller body 2 are provided with fastening end covers 4 for limiting the rolling rings 3, and the middle parts of the fastening end covers 4 are provided with threaded holes 41 corresponding to the external threads 23. Each fastening end cap 4 is screwed to one end of the corresponding roller body 2. And a stop backing ring 5 is arranged between each fastening end cover 4 and the corresponding roller body 2, so that the loosening condition of the fastening end cover 4 is reduced. Specifically, stop backing ring 5 is the rubber backing ring, can exert the pretightning force to rolling circle 3, reduces the gliding condition of rolling circle 3.

Referring to fig. 6, each rolling ring 3 includes an inner ring 31 and an elastic washer 32 wrapping the inner ring 31, and specifically, the elastic washer 32 is made of hard rubber. The circumferential outer surface of each inner ring 31 is provided with a circle of friction increasing convex teeth 311, and the surface of each elastic washer 32, which is attached to the circumferential outer surface of the inner ring 31, is provided with friction increasing concave teeth 321 corresponding to the friction increasing convex teeth 311. The friction increasing convex teeth 311 and the friction increasing concave teeth 321 are matched, so that the situation that the elastic washer 32 and the inner ring 31 slide relatively is reduced. Each elastic washer 32 is provided with a spiral groove 322 on the circumferential outer surface, so that heat is generated during the friction process between the abrasive belt 13 and the plate, and the spiral groove 322 is beneficial to heat dissipation.

The implementation principle of the embodiment is as follows: in contact roller 11 carries out the course of working to panel, panel surface irregularity, the contact roller 11 that compresses tightly panel can receive the reaction force on panel surface, and long-time polishing can make certain position in the surface of contact roller 11 produce corresponding deformation, and then makes the quality of polishing descend, and is not abundant to panel polishing. The surface of the roller body 2 is provided with the rolling rings 3 one by one, and the rolling rings 3 which deform in the contact roller 11 are replaced, so that the surface of the contact roller 11 keeps a better shape. Furthermore, to the unsmooth condition not of uniform in panel surface, the size of the rolling ring 3 of adjustment that can be corresponding is to the specific position in the panel mainly polish for the meticulous and abundant that whole panel polished.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
