Green body grinding equipment and green body grinding method of ceramic bowl automatic forming production line

Abstract

The invention relates to blank body grinding equipment for a ceramic bowl automatic forming production line, comprising a circular turntable, wherein four vertical support pipes are arranged on the turntable; a first sucker is arranged at the top end of each vertical support pipe; the first sucker comprises four functional positions in a circular rotation track revolving around the central axis ofthe turntable; the four functional positions are sequentially a blank moving position, a posture calibration position, a bowl wall grinding position and a bowl bottom grinding position; the four functional positions are uniformly arranged along the circular rotation track; a blank shifting mechanism is arranged beside the blank shifting position, a posture calibrating mechanism is arranged besidethe posture calibrating position, a bowl wall grinding mechanism is arranged beside the bowl wall grinding position, and a bowl bottom grinding mechanism is arranged beside the bowl bottom grinding position. The invention further provides a blank body grinding method of the ceramic bowl automatic forming production line. The equipment and method provided by the invention can automatically grind the outer surface of the bowl wall and the bottom surface of the bowl blank, and can ensure the position, posture and accuracy of the bowl blank during grinding.

Description

technical field [0001] The invention belongs to the technical field of ceramic production technology, and in particular relates to a green body grinding device and a green body grinding method of an automatic ceramic bowl forming production line. Background technique [0002] figure 1 , figure 2 As shown, when the circular ceramic bowl blank 8 is in an upright posture, the bottom of its bowl wall 80 is the bowl foot 81, and the bottom end of the bowl foot is the bowl foot edge 810, and the horizontal projection shape of the bowl foot edge 810 is circular, and the bowl foot edge 810 is circular. sole along 810 at figure 2 Shown in a vertical section passing through the central axis n of the bowl base are points C and D; the circular curved surface surrounded by the bottom of the circular bowl along 810 is called the bottom of the bowl, and the bottom of the bowl 82 is inward relative to the bottom of the bowl 81 Concave, bowl bottom 82 in figure 2 The shown vertical se...

Problems solved by technology

However, the existing automatic equipment for grinding ceramic bodies is mainly suitable for repairing other ceramic products, and it is not ideal when applied to grinding circular ceramic bowl blanks. This is due to the following two reasons:

[0007] 1. It is difficult to fix the position and posture of the round ceramic bowl blank: as we all know, when grinding, the relative position and relative posture between the round ceramic bowl blank and the grinding wheel are required to be accurate, otherwise the quality and effect of grinding will be affected

The part of the round ceramic bowl that needs to be ground is the outer surface (including the bottom surface of the bowl), so the posture of the round ceramic bowl must be reversed, and it is necessary to use negative pressure to tightly suck the round ceramic bowl to make its posture and The position is fixed, therefore, if directly utilize the rim of the bowl edge of circular ceramic bowl blank to support on the horizontal plate 87 and add the limit member 85 when grinding, as Figure 4 As shown, though then can guarantee that bowl blank 8 posture level, stop member 85 also can guarantee that bowl blank 8 positions are accurate, but the sealed space 86 (sealed space such as the sealing space that forms after circular ceramic bowl blank 8 is reversed) Figure 4 (shown in the middle shadow) is too large to be sucked in a short time to form a strong negative pressure, that is, it is difficult to strongly suck the round ceramic bowl blank 8. During the grinding process of the round ceramic bowl blank 8, due to the small suction , it is difficult to resist a certain level of extrusion force exerted by the grinding wheel, the circular ceramic bowl blank 8 may shift, and the edge of the bowl mouth is blocked by the limit member 85 and cannot be ground; on the contrary, if the suction cup 51 is used to hold the inverted Although the bottom of the circular ceramic bowl blank 8 can greatly reduce the sealing space 86, which is conducive to the formation of strong adsorption, it cannot ensure the posture level of the circular ceramic bowl blank 8, that is, the shape of the circular ceramic bowl blank 8. Posture may be tilted out of level, as in Figure 5 As shown, the position may also be inaccurate, and inaccurate position or posture will definitely affect the grinding effect, and even automatic grinding cannot be performed;

[0008] 2. The bottom of the bowl is more difficult to grind due to the indentation: when grinding the bottom of the bowl, if you follow the usual thinking, use such Image 6 , Figure 4 Grinding wheel 30 shown and according to Image 6 Shown arc arrow is rotated grinding, and then in grinding process, bowl bottom surface 82 will be covered by grinding wheel 30 completely, as Figure 4 As shown in the cross section, the crumb powder particles produced in this way cannot leave the grinding surface at the first time, and are always tightly sandwiched between the bowl bottom surface 82 and the grinding wheel 30. Only after the grinding is completed and the grinding wheel 30 leaves the bowl bottom surface, the debris Powder particles can leave the bottom of the bowl, which seriously affects the grinding quality and grinding effect of the bottom of the bowl
