Eccentric turning wheel device

Abstract

The invention discloses an eccentric turning wheel device. The eccentric turning wheel device comprises a frame, a main shaft, adsorption mechanisms, a steering mechanism enabling the adsorption mechanism to rotate at 90 degrees and a negative pressure mechanism providing the adsorption mechanism with negative pressure. An input end of the main shaft is in transmission connection with a synchronizing wheel. An output shaft of the main shaft is provided with a rotary disc in a sleeving ode. A support sleeve is eccentrically in sleeve joint with outside of the main shaft between the synchronizing wheel and the rotary disc and fixed onto the frame. Multiple main bearing seats are fixedly arranged on the support sleeve. The adsorption mechanisms are fixedly mounted onto the main bearing seats. An inside disc body of the rotary disc is in transmission connection with the adsorption mechanisms by means of rocking arm mechanisms. The main shaft and the rotary disc of the turning wheel device are arranged coaxially. The adsorption mechanisms and the main shaft are designed to be eccentric. In the way that the rotary disc drives adsorption boxes to rotate by means of the rocking arm mechanisms for changing rotation speed of the same absorption box, linear velocity of the adsorption boxes is thus changed; and finally speed of the adsorption boxes on a turning wheel is matched with speed of a production line at the front and back portions of the adsorption boxes.

Description

technical field [0001] The invention relates to the field of toilet paper production equipment, in particular to an eccentric indexing wheel device. Background technique [0002] Sanitary paper products such as sanitary napkins, diapers and other finished products are packaged according to the direction of the sanitary napkin on the production line, while others are packaged by rotating the direction of the sanitary napkin on the production line by 90 degrees before proceeding to the next step. [0003] The invention patent of the applicant's patent number CN201220683482.1 discloses an indexing wheel structure, which includes a cam disc, a drive shaft, a cam follower bearing, a guide rod and an adsorption mechanism, wherein the cam disc is fixed on the main shaft sleeve, and the cam disc An inner track guide groove is arranged on the top, and the cam follower bearing is connected with the guide rod through a fixed frame, and is arranged in the inner track guide groove, and a...

Problems solved by technology

Although this structure realizes a 90-degree rotation, due to the complex and time-consuming processing procedures in the early stage of the product, the demand for the production line's circulation speed is relatively low, and in the later stage, there are only pure transfer and bagging, which takes a relatively short time, so it is necessary to increase the operation speed of this section of the transfer process , so it needs to be improved to better match the operation speed requirements of the front and rear processes of the production line
