Cutter device of preservative film packaging machine

Abstract

The invention relates to a cutter device of a preservative film packaging machine. The cutter device is characterized in that two left protection plates are vertically and symmetrically arranged on the outer side wall of a left support plate, and two right protection plates are vertically and symmetrically arranged on the outer side wall of a right support plate; a left sliding rail is arranged between the two left protection plates, and a right sliding rail is arranged between the two right protection plates; a left sliding block is slidably installed on the left sliding rail, and a right sliding block is slidably installed on the right sliding rail; a lower moving beam is fixedly installed between the left sliding block and the right sliding block; a cutter is installed on the lower moving beam; a linear bearing seat is installed at the upper end of the left sliding rail and connected to an air cylinder; an upper moving beam is horizontally installed on the linear bearing seat and connected with a cutter seat through a cutter seat handle; the cutter seat is opposite to the cutter; one end of a stud is connected to the upper moving beam, and the other end of the stud is connectedto the left end of a rocker arm; the right end of the rocker arm is connected to the left sliding block through a connecting rod; and a penetrating shaft is installed between the rocker arm and the left support plate in a penetrating mode. The cutter device of the preservative film packaging machine is scientific and reasonable in structural design, ingenious and simple in structure, low in manufacturing cost, and capable of achieving the efficient packaging of preservative films.

Description

technical field [0001] The invention belongs to the technical field of packaging machinery, relates to a plastic wrap packaging machine, in particular to a cutter device of a plastic wrap packaging machine. Background technique [0002] As a plastic packaging product, plastic wrap has been widely used in people's lives, such as fresh food, fruits and vegetables and so on. In the packaging process of these foods, in order to improve the efficiency of packaging, people often borrow machines, use various knives to cut the plastic wrap, and then pack it, so the cutting device of the plastic wrap packaging machine will be used. [0003] After searching, a similar published patent document was found: [0004] The publication number is CN210102225U, and the name is a patent of a cutting mechanism for a packaging machine. Its technical solution includes a frame on which a cutter and a knife plate are installed, and a power device is installed on the frame to provide power for the c...

Problems solved by technology

[0005] The above patents can realize the cutting of the packaging film, but for the high-height packaging trays filled with materials, the cutting depth of the cutter is not easy to control, and the height requirements of the packaging trays are relatively strict, requiring two different sets of drives Components, power units are more complicated, packaging efficiency is lower, processing is more complicated and cost is higher
