Automatic marking machine

Abstract

The invention discloses an automatic marking machine, comprising a base (1). A vertical block (2) and a press rod (3) are slidably connected on the base (1), the vertical block (2) and the press rod (3) are arranged in parallel, the upper end of the press rod (3) is provided with a flat plate (4), the lower end of the press rod (3) is provided with a puncher (5), and a reset device is arranged between the press rod (3) and the base (1); and a first connecting rod (6) is rotatably connected on the base (1), the base (1) is provided with a first motor for driving the first connecting rod (6) torotate, a free end of the first connecting rod (6) is rotatably connected to a first idler wheel (7) used for abutting against or being separated from the flat plate (4), and a second connecting rod (8) is arranged between the first connecting rod (6) and the vertical block (2). The automatic marking machine which avoids a logo marking negligence phenomenon, and is higher in transmission reliability is provided.

Description

technical field [0001] The invention belongs to the technical field of automatic mechanical processing, and in particular relates to an automatic marking machine, which is used for automatically printing and marking the outer wall of a product. Background technique [0002] The automatic marking machine refers to the marking on the outer wall of the finished product, such as the certificate of conformity, production date, product manufacturing materials, precautions for use and other identifying words. Most of the marking machines in the prior art place the processed products on the conveyor belt, and send the products to the underside of the punch with the characters engraved on the conveyor belt. The punch periodically moves up and down to mark the product located under the punch. However, the product identification obtained in this way has the following shortcomings: First, due to the periodic up and down movement of the punch, once the distance between the products on th...

Problems solved by technology

Most of the marking machines in the prior art place the processed products on the conveyor belt, and send the products to the bottom of the punch with engraved characters through the conveyor belt, and the punch moves up and down periodically to mark the product under the punch. However, the product identification obtained in this way has the following disadvantages: First, because the punch moves up and down periodically, once the distance between the products on the conveyor belt is not equal, it is easy for the punch to fail to contact the product when it goes down , that is, the product cannot be accurately delivered to the bottom of the punch, so it is easy to miss the mark; secondly, since the conveyor belt is a flexible conveying device, it means that the belt of the conveyor belt is a variable and elastic material , once the punch is in contact with the product on the conveyor belt, the conveyor belt will deform, and when the punch leaves the product, the conveyor belt will rebound to return to its original shape. In the process of deformation and rebound of the conveyor belt, The conveyor belt fluctuates; that is to say, every time the punch prints the product on the conveyor belt, the conveyor belt will fluctuate or tremble once, then the conveyor belt will cause the subsequent products to be marked to be displaced relative to the conveyor belt during the fluctuating or trembling process, that is It affects the spacing of subsequent products, and then the punch misses marking due to the fluctuation of the conveyor belt.

To sum up, the marking machine in the prior art still has the phenomenon of missed marking, and the cooperation between the conveyor belt and the punch is not reliable enough, that is, the transmission is not reliable enough.
