Double-speed feeding machine

Abstract

The invention discloses a double-speed feeding machine which mainly solves the technical problem of higher motor radial loads due to longer motor output shafts of existing double-speed feeding machines. The double-speed feeding machine comprises a feeding shaft, a lifting shaft, a fixed crossbeam and an end picker. The lifting shaft is mounted on the crossbeam, the feeding shaft is slidably connected onto the lifting shaft, the end picker is slidably connected onto the feeding shaft, and a synchronous feeding device is arranged in the feeding shaft and comprises a synchronous belt and a synchronous wheel. The synchronous belt is fixedly connected with the end picker and the lifting shaft, a feeding motor is arranged on the lifting shaft, and the feeding motor and the feeding shaft are in transmission through a gear rack pair. The double-speed feeding machine is mainly applied to conveying machinery needing to move quickly at the X-axial direction.

Description

technical field [0001] The invention relates to a double-speed feeding machine, especially a conveying machine that needs to move quickly in the X-axis direction. Background technique [0002] In some high-speed production lines, due to the fast processing speed of products, the traditional belt feeding can no longer meet the production requirements. In order to improve work efficiency, it is necessary to develop a feeding machine with double-speed motion to meet production needs. The State Intellectual Property Office of China published the patent number "200820174463X" on August 5, 2009, and the invention patent named "Robot Double Speed ​​Feeding Mechanism". It is an invention patent of "machinery with X-axis double-speed mechanism". On March 7, 2012, the patent No. "2011201478563" and the invention patent named "a special speed-double mechanism for manipulators for injection molding machines" were published on March 7, 2012. The double-speed mechanism mainly has the fo...

The State Intellectual Property Office of China published the patent number "200820174463X" on August 5, 2009, and the invention patent named "Robot Double Speed ​​Feeding Mechanism". It is an invention patent of "machinery with X-axis double-speed mechanism". On March 7, 2012, the patent No. "2011201478563" and the invention patent named "a special speed-double mechanism for manipulators for injection molding machines" were published on March 7, 2012. The double-speed mechanism mainly has the following defects: 1. The synchronous belt and the pulley are installed on the frame at the same time, the motor drives the bracket and the synchronous belt drive wheel at the same time, and the end picker is connected to the other end of the synchronous belt to achieve double-speed, but the output shaft of the motor It is longer and uses a coupling, which causes the radial load of the motor to be too large, the torque of the motor cannot be output stably, and the reliability of the mechanism is poor; Both are tensioned, the structure is complex, and it takes up a lot of space
