Ceramics throwing machine of inner engagement tooth type ratchet mechanism

Abstract

The invention discloses a ceramics throwing machine of an inner engagement tooth type ratchet mechanism. The ceramics throwing machine comprises a supporting table. A motor box is fixed to the bottomof the supporting table. A drive motor is fixed to the bottom of the motor box. A reduction gearbox is arranged above the drive motor. A rotating rod penetrates out of the reduction gearbox from a rotating rod bearing. The rotating rod bearing is arranged on the right side of the box top of the reduction gearbox. The top end of the rotating rod is fixed to a drive disc. A pawl rotating shaft is fixed to the surface of the top of the drive disc. A pawl is rotationally fixed to the top of the pawl rotating shaft. A spring piece is fixed to the left side of the pawl. A ratchet is arranged over the drive disc. The pawl and the inner groove wall of the ratchet are engaged. The top of the ratchet is fixed to the bottom of a throwing rotating rod. The throwing rotating rod penetrates a connectingrod hole. A rotary rod bearing is arranged in the connecting rod hole in a sleeved manner. A throwing rotating disc is fixed to the top of the throwing rotary rod. A water basin is fixed to the top of the supporting table. According to the ceramics throwing machine, the ratchet and the pawl are connected in an inner engagement manner, connecting is more stable, and loosening and falling are not prone to happening.

Description

technical field [0001] The invention relates to the field of ceramic production, in particular to a pottery drawing machine with an internal meshing tooth type ratchet mechanism. Background technique [0002] The pottery drawing machine is a commonly used equipment in the process of making pottery. It mainly plays the role of base and rotation in the process of pottery making. It is generally composed of the body shell, shell bracket, chain (or gear) , ratchet, drawing turntable, and other components. [0003] The purpose of the ratchet is: during the pottery production process, when the overall shape of the pottery needs to be finalized, the drawing base needs to be rotated quickly, but when the part of the pottery is depicted or the shape is changed, it is no longer necessary. Generally, the producer uses the hand to rotate the drawing base to fine-tune the rotation according to his own needs. Because there is a rotational connection between the drawing base and the rotat...

Problems solved by technology

[0003] The purpose of the ratchet is: during the pottery production process, when the overall shape of the pottery needs to be finalized, the drawing base needs to be rotated quickly, but when the part of the pottery is depicted or the shape is changed, it is no longer necessary. Generally, the producer uses the hand to rotate the drawing base to fine-tune the rotation according to his own needs. Because there is a rotational connection between the drawing base and the rotating motor, this causes the motor shaft of the rotating motor to be linked together during the rotation process. Therefore, it is very laborious. The role of the ratchet here is to convert the fixed rotational relationship between the drawing base and the rotating motor into a sliding rotational relationship when the rotating motor stops rotating. When the drawing base rotates, there is no need to pull the rotating motor to rotate together. , so that the turning process is very labor-saving and more convenient for pottery makers to create. However, the current ratchet is generally connected externally with the rotating motor and the drawing base, and it is easy to loosen and slip during long-term use, which will affect the working effect of the ratchet. Therefore, we need A more stable ratchet connection structure
