Perforating device for food packaging paperboard

Abstract

The invention discloses a perforating device for a food packaging paperboard. The perforating device for the food packaging paperboard comprises a bottom plate, a supporting column, a top plate, an adjusting shaft, a supporting block, threaded parts, a first threaded sleeve, a first sliding groove, a first sliding block, a connecting rod, a lifting plate, a fixing plate and a lead screw. A secondthreaded sleeve is mounted on the lead screw. The two threaded parts are in central symmetry along the adjusting shaft. The spiral directions of threads of the two threaded parts are opposite. A mounting device is mounted on the outer wall of the lower end of the second threaded sleeve through a connecting part. A perforating rod is mounted in the lower end of the mounting device. The overall structure of the perforating device adopts the mechanical principles well known by people skilled in the art, any complex electrical equipment or control system is not used, paperboard perforating operation can be achieved rapidly through simple manual operation, the position adjustment of the perforation rod can be achieved through the lead screw, omnidirectional perforating of the paperboard can beachieved, the paperboard does not need to be moved after being fixed, and the perforating position can be changed just by changing the position of the perforating rod.

Description

technical field [0001] The invention relates to food packaging cardboard processing equipment, in particular to a punching device for food packaging cardboard. Background technique [0002] Food packaging is an integral part of food commodities. One of the main projects in the food industry process. It protects the food and prevents the damage of biological, chemical and physical external factors during the circulation of the food from the factory to the consumer. It can also have the function of maintaining the stable quality of the food itself. It is convenient for the consumption of food. It is also the image that first expresses the appearance of food and attracts consumption, and has value other than material cost. Therefore, food packaging process is also an inseparable part of food manufacturing system engineering. However, the versatility of the food packaging process makes it have a relatively independent self-system. [0003] Food packaging is inseparable from ...

Problems solved by technology

[0003] Food packaging is inseparable from the use of cardboard. Cardboard needs to be processed before packaging. Among them, cardboard punching is essential. The purpose of cardboard punching is mainly to keep the box air-permeable, and some are to facilitate the handling of the box. As a whole, punching machines are indispensable when punching these cardboards. As the name suggests, punching machines are machines for punching holes. Traditional cardboard punching is done manually. Most of the existing punching machines are highly mechanized. However, for some small workshops, mechanically operated punching machines are not only expensive but also troublesome to maintain, so manual punching machines are still indispensable, but most of the existing manual punching machines are push-down , long-term operation will make the palm tired, and at the same time, most of the punching needles of these punching machines are fixed. After the cardboard is fixed, if you want to change the punching position, you need to reposition the cardboard, which is very troublesome, so it needs to be improved.
