Filling reversing structure

Abstract

The invention discloses a filling reversing structure. The filling reversing structure is characterized by comprising a cam power device, a reversing control structure and an executing mechanism, wherein the cam power device is used for providing transmission power to the device, and comprises a cam; the middle part of the cam is provided with a through hole for connecting a motor output shaft, and connected with a swinging arm by a cam slot formed in the cam; the end part of the swinging arm is connected with the reversing control structure by a hoop; the reversing control structure comprises an air cylinder and an air cylinder tension rod, wherein the air cylinder tension rod is connected with the air cylinder; the air cylinder drives a control rod to move; the control rod is connected with a hanger control rod mechanism to drive the hanger control rod mechanism to move; the executing mechanism comprises a movable rod which is connected with the reversing control structure, wherein the end part of the movable rod is connected with a rotary valve swinging arm; and the rotary valve swinging arm rotates up and down along with the motion of the movable rod, so that reversing motion is achieved. The filling reversely structure not only achieves transmission integration, but also well achieves transmission automation, so that the operation of the product is stable, the cost is low, a way of controlling a large part with a small part is delicately achieved, and the cost performance is relatively high.

Description

technical field

[0001] The invention relates to the field of filling equipment, in particular to a filling reversing structure. Background technique

[0002] There are many existing domestic filling and reversing structures, most of which are directly driven by the cylinder to complete the reversing. Since the stroke of the cylinder required for this reversing is relatively long, there is a certain time difference between the start of the cylinder, and the accuracy of the reversing transmission cannot be guaranteed. It is not conducive to the realization of high-speed automation of filling. Some foreign reversing structures are too complex and costly, which is not conducive to popularization. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a filling reversing structure, which not only solves the integration of the transmission, but also solves the automation of the transmission well, the product runs stably, and...
