Description

Cutting device and plastic wrap box having the same

The invention relates to a daily necessities, in particular to a cutting device and a wrap film therewith

Background technique

In order to preserve food, people are using plastic wrap more and more frequently.

The cling film is generally elongated and continuously wound on the core barrel with a certain width, and the cutting length is determined as needed.

The cutting device for the cling film is a sawtooth piece, which is correspondingly disposed at the film opening position of the wrap box. When the wrap film is pulled out by the required length, the wrap film is swung downward to make it contact the saw blade, and the force is applied. Pull until the cling film is cut.

Since the wrap film is made of plastic, it is easily deformed when the thickness is thin. Therefore, when the serrated piece is pulled, the fracture is not neat, and even the local deformation is serious, resulting in waste of the wrap film. Summary of the invention

In order to solve the above-mentioned prior art problems, the present invention provides a cutting device and a wrap box having the same, and a slider having a V cutter is provided. When cutting is required, the slider is directly from the first limit end. Move to the second limit end, or move the second limit end to the first limit end, and the cling film contacting the V cutter is cut off, thereby obtaining a neat fracture, which is labor-saving and convenient.

The present invention solves the above-mentioned prior art problems and provides a cutting device including a guide rail and a slider.

a V-cutting knife, a first limiting end and a second limiting end; the first limiting end and the second limiting end are located at the The two ends of the guide rail, the slider is matched with the guide rail; the V cutter is fixedly connected to the slider.

Further improvements of the invention are as follows.

The cutting direction of the V cutter is the same as the moving direction of the slider.

The V cutter is one on one side of the slider.

The V cutters are two and are located on both sides of the slider.

The present invention solves the above-mentioned problems of the prior art, and provides a wrap box having a cutting device, the wrap box comprising the cutting device; the wrap box further comprising a box body and a film exit opening, The cutting device is disposed opposite the exit opening.

Further improvements of the invention are as follows.

A wrap film is also included, and the wrap film is housed in the wrap film box.

The free end of the wrap film is drawn from the film outlet.

Compared with the prior art, the beneficial effects of the present invention are: setting a slider with a V cutter, directly moving the slider from the first limit end to the second limit end, or second The limit end is moved to the first limit end, and the plastic wrap that contacts the V cutter is cut off, thereby obtaining a neat fracture, which is labor-saving and convenient.

The cutting device has no high-precision requirements, and only the V cutter can cut the wrap film, so the structure is simple and the production cost is low. DRAWINGS

Fig. 1 is a schematic view showing the structure of a cutting device of the present invention having a V cutter.

Figure 2 is a schematic view showing the structure of the cutting device of the present invention having two V cutters.

Fig. 3 is a schematic view showing the structure of a wrap film box of the present invention. detailed description

The invention will now be further described with reference to the drawings and specific embodiments.

As shown in FIG. 1 to FIG. 3, a cutting device 1 includes a guide rail 11, a slider 12, a V cutter 13, a first limit end 14 and a second limit end 15, and the slider 12 is aligned with the guide rail 11. Cooperating, the slider 12 can be reciprocated along the guide rail 11, and the first limiting end 14 and the second limiting end 15 are located at both ends of the guide rail 11, ensuring that the slider 12 is located at the first limiting end 14 and the second limit The guide rail 11 between the bit ends 15; the V cutter 13 is fixedly coupled to the slider 12, and when the V cutter 13 is moved against the wrap film 21, the cutting operation is realized.

The cutting direction of the V cutter 13 is the same as the moving direction of the slider 12, that is, the cutting direction of the V cutter 13 is along the extending direction of the guide rail 11, so that how the guide rail 11 is placed relative to the exit opening 221 determines that the wrap film 21 is cut. shape.

In general, the V cutter 13 is one, disposed on one side of the slider 12, and the slider 12 is again located at the fixed end of the guide rail 11. When one cut is completed, the slider 12 is reset from the cut end to the fixed end. . Alternatively, there are two V cutters 13 which are located on both sides of the slider 12. When one cut is completed, the slider 12 is moved from one end to the other end, and after the cutting is completed again, the slider 12 is moved from the other end to the other end. end.

The guide rail 11 of the present invention can be made of a plastic material, and the V cutter 13 can also be made of a plastic material or a metal material, but it needs to be a hard material to prevent the cutting edge from being worn, thereby affecting the cutting effect.

As shown in FIGS. 1 to 3, a wrap box 2 having a cutting device 1 includes a case 22, a film outlet 221, and a cutting device 1, and the cutting device 1 is disposed opposite the film opening 221 . At this time, the wrap film cassette 2 can be repeatedly used. When the wrap film 21 is used up, a roll of the wrap film 21 can be replaced, and the cutting length of the cutting device 1 is required to be larger than the width of the wrap film 21. Alternatively, the wrap film cassette 2 has a wrap film 21, and the wrap film 21 is housed in the wrap film box 2, and the free end of the wrap film 21 is taken out from the film exit port 221.

The cutting device 1 includes a guide rail 11, a slider 12, a V cutter 13, a first limit end 14 and a second limit end 15, and the slider 12 cooperates with the guide rail 11 so that the slider 12 can reciprocate along the guide rail 11. Moving, the first limiting end 14 and the second limiting end 15 are located at both ends of the guide rail 11 to ensure that the slider 12 is located on the guide rail 11 between the first limiting end 14 and the second limiting end 15; The knife 13 is fixedly coupled to the slider 12, and when the V cutter 13 is moved against the wrap film 21, the cutting operation is realized.

A slider 12 having a V cutter 13 is provided. When cutting is required, the slider 12 is directly moved from the first limiting end 14 to the second limiting end 15, or the second limiting end 15 is moved to the first limit. At the bit end 14, the wrap film 21 contacting the V cutter 13 is cut, thereby obtaining a neat fracture, which is labor-saving and convenient.

The cutting device 1 is not required to have high precision, and only the V cutter 13 is required to be able to cut the wrap film 21, so that the structure is simple and the production cost is low. The cutting device 1 cuts the wrap film 21 by:

First pull out the appropriate length of the film cover on the required items;

Then moving the wrap box 2 down;

Then, one side of the wrap film 21 outside the film opening 221 is placed in the V-shaped opening of the V cutter 13; finally, the slider 12 is moved to move the slider 12 from one end of the guide rail 11 to the other end;

Thus, the wrap film 21 of the desired length and neatly cut is obtained.

The above is a further detailed description of the present invention in connection with the specific preferred embodiments, and the specific embodiments of the present invention are not limited to the description. It will be apparent to those skilled in the art that the present invention may be made without departing from the spirit and scope of the invention.
