Problems solved by technology

When using this product, users first need to remove the heat-shrinkable film on the outer surface of the packaging box, and the packaged heat-shrinkable film is difficult to tear open with bare hands
Correspondingly, how to realize the easy-tear opening on the heat-shrinkable film has become a problem to be considered. The position of the cutter of the existing easy-tear equipment is mostly fixed. When the cut surface of the packaging box is uneven , the quality of easy tearing is difficult to guarantee

Embodiment 2

[0033]The easy-to-tear device in Embodiment 2 is roughly the same as that in Embodiment 1, the difference is that the cutter 33 in Embodiment 2 is roughly in the shape of a circular sawtooth, and the cutter speed adjustment device in Embodiment 1 is controlled by a cutter. The knife controller (not shown) replaces. While the slider 42 slides along the surface to be cut, the cutter 33 rolls along the surface to be cut. The cutting knife controller can apply a constant pressure to the cutting knife 33, so that the cutting knife 33 can cut out a dotted-line easy-tear opening in the rolling process in the way of hard pressure cutting. In this embodiment, a gasket is provided between the packaging box 21 and the packaging film to prevent the packaging box 21 from being cut.

Embodiment 3

[0035] The easy-to-tear device of the third embodiment is roughly the same as that of the second embodiment, the difference is that the cutter 33 of the second embodiment is roughly needle-shaped or flat-shaped, and the cutter controller not only exerts pressure on the cutter 33, but also controls The cutting knife 33 reciprocates up and down, and cuts out a dotted line-shaped easy-to-tear opening on the cut surface.

[0036] When the easy-to-tear device provided by the present invention cuts the easy-to-tear opening, the bottom of the cutter 33 and the bottom of the slider 42 have a fixed height difference. The easy-to-tear opening with uniform depth is cut on the packaging film, effectively ensuring the quality of the easy-tear opening, and avoiding damage to the packaging box 21 or not cutting the packaging film.

Abstract

The invention discloses an easy-to-tear opening device which comprises a base, a box feeding component, a positioning component and a cutting component. The positioning component comprises a sliding block and sliding block floating arm, the sliding block floating arm is rotatably connected with the side wall of the base, and the sliding block is arranged at one end of the sliding block floating arm; the cutting component comprises a cutter and a cutter floating arm, the cutter floating arm is also rotatably connected with the side wall of the base, the cutter is arranged at one end of the cutter floating arm, the bottom of the cutter is kept at a fixed height difference with the bottom of the sliding block, the box feeding component is arranged on the bottom plate of the base, the packingbox to be cut is conveyed by the box feeding component, the sliding block is attached to and sliding along the surface of the packing box and drives the sliding block floating arm to swing up and downwhile the packing box is in motion, the cutter floating arm swings synchronously with the floating arm of the sliding block, and the cutter cuts out the easy-to-tear opening on the surface of the packing box as the cutter floating arm moves up and down.

Description

technical field [0001] The invention relates to the field of packaging, in particular to an easy-to-tear device. Background technique [0002] With the development of the circulation of the commodity economy, after the products are assembled, they often need to be transported over long distances for circulation. Correspondingly, the product is usually packed into a packing box to avoid damage during long-distance transportation and to facilitate circulation. Generally speaking, in order to improve the sealing performance of the packaging box, such as waterproof and air leakage prevention, in the prior art, a layer of heat-shrinkable film is usually wrapped on the outer surface of the packaging box. When using this product, users first need to remove the heat-shrinkable film on the outer surface of the packaging box, and the packaged heat-shrinkable film is difficult to tear open with bare hands. Correspondingly, how to realize the easy-tear opening on the heat-shrinkable f...
