Problems solved by technology

[0003] Since the existing ejection device mainly uses the cylinder as the driving part, and the ejection direction of the cylinder is consistent with the ejection direction of the material, the ejection direction of the material is a single linear direction, which cannot meet the requirements of two-way ejection in the vertical direction. The scope of use is relatively narrow, and often cannot meet functional requirements
At the same time, this type of structure cannot accurately displace the material, the movement accuracy is low, and it is not stable during the movement process, and the wear is large, resulting in a high failure rate and a problem of limited service life.

Abstract

The invention belongs to the technical field of automation equipment, and discloses an ejection device. The ejection device includes a driving member, a first ejection member, a second ejection member, a first transmission assembly and a second transmission assembly; two ends of the first transmission assembly are connected with the output end of the driving member and the first ejection member separately; the second transmission assembly and the first transmission assembly are arranged symmetrically on both sides of the driving member, and both ends of the second transmission assembly are connected with the output end of the driving member and the second ejection member; the driving member is configured to jointly drive the first transmission assembly and the second transmission assemblyto move, so that the first ejection member and the second ejection member move toward each other or away from each other, the function of two-way ejection is realized, the ejection device is used forcompleting processes of precision ejection, precision displacement and precision extension and contraction in various automation equipment, the range of application is wide, and the diverse needs of users can be met.

Description

technical field [0001] The invention relates to the technical field of automation equipment, in particular to an ejecting device. Background technique [0002] In the field of automation equipment, most of the existing ejection devices adopt the structure of the cooperation of the cylinder and the guide shaft, or the cooperation of the cylinder and the linear bearing, mainly relying on the expansion and contraction of the cylinder to directly control the ejection position of the material. [0003] Since the existing ejection device mainly uses the cylinder as the driving part, and the ejection direction of the cylinder is consistent with the ejection direction of the material, the ejection direction of the material is a single linear direction, which cannot meet the requirements of two-way ejection in the vertical direction. The scope of use is relatively narrow, and often cannot meet functional requirements. At the same time, this type of structure cannot accurately displa...
