Embodiment 1

[0032] See Figure 1-2 , a plastic film cutting device based on roll cutting technology, comprising a frame 1, the frame 1 is a U-shaped structure, the bottom of the frame 1 is evenly provided with a number of legs 2, the inner cavity of the frame 1 The middle part is provided with a cutting plate 6 and two preloading drive mechanisms 5, and the two preloading drive mechanisms 5 are symmetrically arranged on the left and right sides of the cutting plate 6, and the preloading drive mechanism 5 and the cutting plate 6 are on the same straight line The left side of the inner cavity side wall of the frame 1 is fixedly connected to the first rotating shaft 4, and the first rotating shaft 4 is provided with a feed roller 3 for rotation, and the right side of the bottom end of the frame 1 is provided with an outlet The material hole 8, the right side of the inner chamber bottom wall of the frame 1 is provided with a deflector 7 matched with the discharge hole 8, and the middle part o...

Embodiment 2

[0035] See image 3 The difference from Embodiment 1 is that one side end of the cutting knife 93 is provided with a lock hole 931, and the outer circular surface of the cutting roller 92 is evenly provided with a number of sipes that match the cutting knife 93. 921, the side wall of the knife groove 921 connects with the lock groove 922, the lock groove 922 is an arc-shaped groove, an electromagnet assembly 924 is installed on the inner cavity wall of the lock groove 922, and the lock groove 922 is slidingly connected There is a slide block 923 matched with the electromagnet assembly 924, and one side end of the slide block 923 is fixedly connected with a lock bar 926 matched with the lock hole 931, and one end of the slide block 923 close to the electromagnet assembly 924 is passed through a pre-tension spring 925 is fixedly connected on the inner cavity wall of the locking groove 922, the locking rod 926 is an arc rod, and the radian of the locking rod 926 is the same as th...

Embodiment 3

[0037] See Figure 4 The difference from Embodiment 1 is that: the pretension driving mechanism 5 includes two driving rollers 51, the two driving rollers 51 are symmetrically arranged up and down, and the two driving rollers 51 are tangentially matched, and the driving rollers 51 Rotately connected on the frame 1 by a drive shaft 52, one end of the drive shaft 52 runs through the side wall of the frame 1 and is rotatably connected to an external motor (not shown in the figure), and the drive shaft 52 is rotatably connected to the frame 1 Above, use the external motor to cooperate with the driving shaft 52 to drive the two driving rollers 52 to rotate in opposite directions, and use the two driving rollers 52 to squeeze and drive the plastic film to realize the sliding of the plastic film on the cutting plate 6, thereby ensuring the continuity of the plastic film feeding , and then ensure the continuity of the entire cutting work; the two driving rollers 51 cooperate to ensure...

Abstract

The invention discloses a plastic film cutting device based on a rolling cutting technology and a cutting method thereof.The plastic film cutting device comprises a rack, a plurality of supporting legs are evenly arranged at the bottom end of the rack, a cutting plate and two pre-tightening driving mechanisms are arranged in the middle of an inner cavity of the rack, and the two pre-tightening driving mechanisms are symmetrically arranged on the left side and the right side of the cutting plate respectively; the left side of one side wall of the inner cavity of the rack is fixedly connected with a first rotating shaft, the first rotating shaft is rotationally sleeved with a feeding roller, a discharging hole is formed in the right side of the bottom end of the rack, a flow guide plate matched with the discharging hole is arranged on the right side of the bottom wall of the inner cavity of the rack, and a cutting mechanism matched with a cutting plate is arranged in the middle of the top end of the rack; and a guide roller matched with the feeding roller is arranged in the inner cavity of the rack, and the guide roller is rotationally connected to the rack through a second rotating shaft. The whole cutting process is automatically completed, manual participation is not needed, the machining efficiency is greatly improved, and the use requirement of large-scale cutting work can be met.

Description

technical field [0001] The invention relates to the technical field of plastic film production, in particular to a plastic film cutting device and a cutting method based on roll cutting technology. Background technique [0002] Plastic film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, used for packaging and as a coating layer. Plastic film is extruded by extruder, plastic film can be used for food packaging, electrical product packaging, daily necessities packaging, clothing packaging and so on. Existing plastic films are all made into a large roll, so they need to be cut according to actual conditions during use. [0003] Plastic films are most widely used in the packaging field. They have one thing in common, that is, color printing must be performed on plastic films, and multi-layer lamination or vacuum aluminum plating must be performed as food packaging. Therefore, it is required that the surface free energy of the ...
