Automatic material feeding, taking and pressing production line for malleable material

Abstract

The invention provides an automatic material feeding, taking and pressing production line for a malleable material. The automatic material feeding, taking and pressing production line comprises a material feeding device, a material pressing device and a material taking device. Firstly, a hopper stops at a discharging port of a material distributing machine for material preparation, closing of a hopper cover is kept through a hopper switch locking device, a hydraulic cylinder is controlled through hydraulic driving, a material feeding manipulator telescoping mechanism is pushed to complete material feeding, an upper pressing oil cylinder is controlled through hydraulic driving, a material pressing machine piston is pushed to an upper pressing plate to press down and compress the material into blocks; secondly, liquid enters a lower cavity of the upper pressing oil cylinder, a piston and a movable cross beam are pushed to achieve return stroke motion, meanwhile a material taking telescoping mechanism and a lifting mechanism are hydraulically driven to complete formed material positioning of a material taking manipulator. Clamping mechanisms of fingers utilize a push rod and slide block mechanism to decide clamping and loosening of the manipulator according to different positions of the hydraulic cylinder, and the fingers moves on a polished bar to achieve clamping of the materialblocks; finally, a piston rod is hydraulically driven to perform return stroke motion, and the formed material is placed on a conveying belt for material conveying.

Description

technical field [0001] The invention relates to an automatic feeding and pressing production line for plastic materials, belonging to the field of intelligent manufacturing. Background technique [0002] The development of modern production and science and technology puts forward higher and higher requirements for automation technology, and also provides necessary conditions for the development of automation technology. After the 1970s, automation technology began to develop towards complex electrical automation system control and advanced intelligent control, and was widely used in various fields such as national defense, scientific research and economy to achieve larger-scale automation. Automation has become a symbol of modern industry, and the application degree of automation has also become a measure of a country's industrial development level. Due to the late start of my country's modern industry and relatively backward technology base, the application of automation i...

Problems solved by technology

Due to the late start of my country's modern industry and relatively backward technology base, the application of automation in my country is limited to specific fields, and many operations in most fields are still done manually, so the production efficiency is low and a lot of labor is wasted.

[0003] At present, the pressing machine is the most widely used domestic pressing production device, but it is bulky and has a large workbench area, and most of the feeding and retrieving of the pressing machine is manual packing and unloading, and a few are automatic feeding and retrieving. Low production efficiency and difficulty in mass production

The main problems are: first, which arm design method should be used to improve the length of the arm of the feeding and retrieving manipulator, so as to avoid the large bending moment formed when the arm is extended too long, which will affect the positioning accuracy of the manipulator and reduce the life of key components. Components cause stress, increasing the difficulty of material selection

The second is how to solve the problem that the longer manipulator arm will make the whole rack larger and the overall weight will be larger, which will cause inconvenience in transportation and handling

But no matter what kind of guiding method, the weight of the guiding device must be added to the arm, which increases the weight of the arm and causes a greater bending moment
