Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the utility model provides a blank grinding machine, which comprises a workbench 1, a rack groove 2 and a blank grinding device arranged in the rack groove 2, wherein the workbench 1 is provided with a conveying device 3 corresponding to the blank grinding device; the blank grinding device comprises a cross beam 4, a lifting frame 5 for driving the cross beam to lift and a grinding mechanism 6 arranged on the cross beam, wherein the cross beam 4 is provided with a connecting groove 41 for adjusting the transverse position of the grinding mechanism 6; the lifting frame 5 comprises a vertical frame 51 and a driving mechanism for driving the cross beam to lift, and the cross beam 4 is connected to the vertical frame 51 in a sliding mode.

Specifically, referring to fig. 2, the driving mechanism includes a screw 52 mounted on the stand, a screw lifting seat 53 adapted to the screw 52, and a first motor 54 for driving the screw, the cross beam 4 is connected to the screw lifting seat 53, the screw lifting seat 53 is mounted on the screw 52, and when the first motor 54 drives the screw 52 to rotate, the screw lifting seat 53 moves along the screw 52, thereby controlling the feeding amount of the polishing mechanism mounted on the cross beam 4.

Because the grinding mechanism has a large weight, in order to reduce the radial stress of the screw 52, the stand 51 is provided with a lifting slide rail 55, the cross beam 4 is provided with a slide block 42 matched with the lifting slide rail, and the cross beam 4 is connected to the lifting slide rail 55 in a sliding manner through the slide block 42.

In terms of installation of the grinding mechanism, the grinding mechanism 6 comprises a grinding disc 61, a driving shaft 62 and a second motor 63, wherein the second motor 63 drives the grinding disc 61 to rotate through the driving shaft 62. Grinding machanism 6 still includes the motor connecting piece, the motor connecting piece is including locating respectively the connecting plate 64 at both ends about second motor 63, two upper and lower connecting plates 64 outwards extend in order to form the confession 4 male joint space of crossbeam, and so setting can realize the primary connection of second motor 63 and crossbeam 4 under the condition of no bolted connection between connecting plate 64 and crossbeam 4 to make things convenient for later stage bolted connection, and grinding machanism 6's position adjustment, need not extra support of people's hand. Accordingly, the connecting plate 64 is provided with a connecting hole corresponding to the connecting groove 41 for bolt connection. The first motor 54 and the second motor 63 are generally provided with a transmission, and the connection plate 64 may be provided at both upper and lower ends of the transmission of the second motor 63.

Because the specifications of the green bricks are different and the width of the green bricks is larger than that of the grinding discs by a few, the grinding discs with large diameters need to use high-power motors and the maximum rotating speed is limited, thereby influencing the best grinding effect. Therefore, the blank grinding device is provided with at least 2 grinding devices, so that the maximum grinding width of the blank grinding device is increased in a mode that a plurality of grinding discs are transversely arranged.

Because the working position of the grinding disc 61 is outside the frame groove 2, the bottom of the frame groove 2 is provided with a rotating shaft hole 21 for the driving shaft to pass through so as to drive the grinding disc 61 outside the frame groove 2.

Since the spindle hole 21 limits the adjustment range of the drive shaft 62 within a certain range, the positional adjustment range of the grinding mechanism 6 on the cross member 4 is affected. Therefore, in order to avoid the region between two adjacent grinding discs 61 where grinding cannot be performed, the minimum horizontal distance between two adjacent rotating shaft holes 21 is smaller than the diameter of the grinding disc, so that the grinding ranges of two adjacent grinding discs 61 are overlapped.

Referring to fig. 3, the transportation device 3 includes a transportation chassis 31, driving rollers 32 disposed at front and rear ends of the chassis, and a transportation belt 33 mounted on the driving rollers, wherein the driving rollers 32 drive the transportation belt 33 to rotate so as to drive the green bricks to be ground by the grinding disc 61.

Furthermore, in order to increase the rigidity of the conveyor belt 33 for supporting the tiles, the conveyor base 31 is provided with a plurality of support plates 34 for supporting the conveyor belt.

Further, because the grinding disc 61 is used for grinding the green bricks in a rotating manner, acting force deviating from the conveying direction of the conveying belt 33 is generated on the green bricks, so that the conveying belt deviates, and the normal operation of the conveying belt 33 is finally influenced. Therefore, the two sides of the front and rear ends of the transportation chassis 31 are provided with limiting blocking pieces 35 for limiting the deviation of the transportation belt 33. The limiting stop piece 35 will abut against the side edge of the conveyor belt 33 to limit the deviation of the conveyor belt.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the utility model.
