Gripper device of high frequency die cutting machine

Abstract

The invention discloses a gripper device of a high-frequency die cutting machine. The gripper device comprises a machine frame, a front guide mechanism, a gripper bar lifting mechanism, a front guide position gripper bar positioning mechanism, a gripper bar opening-closing mechanism and a chain transmission mechanism. A gripper opening slide plate mechanism is connected to a transmission chain of the chain transmission mechanism, and a gripper bar for clamping paper is installed on the gripper opening slide plate mechanism. The gripper bar lifting mechanism descends to push the gripper bar into the front guide position gripper bar positioning mechanism, the gripper bar opening-closing mechanism opens the gripper bar to wait for the paper to be fed into a gripper of the gripper bar, and the paper is lifted through a front guide rod in the front guide mechanism after being positioned by the front guide mechanism. The paper is clamped on the gripper bar after gripper bar opening-closing mechanism ascends to close the gripper bar, and the gripper bar moves on the working plane of the machine frame through the chain transmission mechanism after clamping the paper. The gripper device achieves automatic paper feeding, improves paper feeding speed, is high in paper positioning accuracy and further ensures paper weight, accordingly production efficiency is improved, processing effect is improved, and waste is reduced.

Description

technical field [0001] The invention relates to the field of die-cutting machinery, in particular to a gripper device of a high-frequency die-cutting machine. Background technique [0002] High frequency die cutting machine is the main equipment in the printing and packaging industry. The high-frequency principle generates a high-frequency electromagnetic field by a tube self-excited oscillator. The paper to be processed is pressed between the upper and lower electrodes with a high-frequency electromagnetic field, and its internal molecules are excited and high-speed motion rubs against each other to generate heat and melt, and achieve the purpose of welding or indentation under the pressure of the mold; die-cutting machine The working principle is to use the template carved by steel knife, metal mold, steel wire or steel plate, apply a certain pressure through the embossing plate, and cut the printed matter or cardboard into a certain shape. The main parts of the die-cutt...

Problems solved by technology

[0003] The high-frequency die-cutting machine needs to transport the paper to the die-cutting station for processing when it is working, but the existing high-frequency die-cutting machine mainly transports the paper to the die-cutting station for processing when it is working. Since the accuracy and stability of paper conveying is an important factor affecting the working quality of the die-cutting machine, the cardboard must be accurately conveyed to the station at a speed of 60-80 sheets per minute during work.

In order to achieve this goal, most of the paper feeding mechanisms on the market are driven by intermittent motion boxes, and are composed of conveyor chains, tooth rows and other components. The highest positioning accuracy is only 0.075 mm, and there are disadvantages such as complex mechanism, loud noise, high cost, low yield rate and poor paper quality
