Two-hole perforating device for food packaging box side wall paper board

Abstract

The invention discloses a two-hole perforating device for a food packaging box side wall paper board. The two-hole perforating device comprises a pedestal, supporting plates, a top plate, a lifting plate, mounting blocks, a first adjusting shaft, first threaded parts, first swivel nuts, connecting pieces, perforating rods, a platform plate, a driven bevel gear, a driving bevel gear and a first motor. Sliding chutes are formed in the lower end of the lifting plate and are further located over the first threaded parts. Sliding blocks are installed on the outer walls of the upper ends of the first swivel nuts, and the top ends of the sliding blocks are arranged in the sliding chutes in a sliding mode. By means of the two-hole perforating device for the food packaging box side wall paper board, the distance between the two perforating rods can be adjusted through the first adjusting shaft, the distance between two holes perforated in the paper board can be adjusted conveniently, and perforating can be conducted as required; movement of the paper board in the perforating mode can be avoided through pressing blocks, and the phenomenon that the paper board is carried away by the perforating rods can also be avoided; and meanwhile, due to arrangement of a half bevel gear, ascending and descending of the lifting plate can be adjusted in a circulation mode without changing the rotating direction of a second motor, and the service life of the second motor is prolonged.

Description

technical field [0001] The invention relates to a punching machine, in particular to a double-hole punching device for side wall panels of food packaging boxes. 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 paper packaging boxes. Paper packaging boxes are often the last process of food packaging. When food is packaged in paper packaging boxes in factories, in order to facilitate subsequent handling, often put There are two through holes on the opposite side walls. These two through holes are set to facilitate the insertion of fingers by the carrier and imp
