Description

Cutting pad for easy work

This invention relates to a cutting pad, and more particularly to a cutting pad that facilitates work.

The cutting pad is used in various fields such as sewing, patchwork, paper craft and model making. When a knife is used to cut an object, the cutting pad is placed under the object, and the blade of the knife does not contact the workbench under the cutting pad.

In order to prevent the object from sliding during the cutting process, a cutting pad that can be used in conjunction with a magnet is developed. The cutting pad is mainly composed of a layered structure consisting of a surface layer, a metal plate and a bottom layer stacked in sequence, wherein the surface layer is a thin plate body made of soft thermoplastic resin, the metal plate is a thin plate body made of iron metal or other magnetically conductive metal materials, and the bottom layer is a thin plate body made of thermoplastic resin. The surface layer and the metal plate are bonded together, and the metal plate and the bottom layer are bonded together.

When cutting a sheet-shaped object, the object is placed flat on the surface, and the magnet is stacked on the object. The magnetic attraction between the magnet and the metal plate enables the magnet to press and position the object.

The metal plate has different material properties from the surface layer and the bottom layer, and it is difficult to directly connect them effectively. Therefore, the surface layer and the metal plate are bonded by bonding means, and the metal plate and the bottom layer are also bonded by bonding means. Regardless of whether the bonding means is achieved by adhesive or double-sided adhesive film, the bonding strength is easily reduced due to moisture penetration in the air, temperature and humidity changes or other factors. The surface layer and the metal plate are easily peeled off from each other, and the metal plate and the bottom layer are also easily peeled off from each other, affecting the service life of the cutting pad. After the metal plate and the bottom layer are peeled off, the flat and thin edge of the metal plate is easy to cut the user.

The main purpose of this creation is to provide a cutting pad that is convenient for work. To achieve the above purpose, this creation adopts the following technical solutions:

A cutting pad for convenient work includes a first cutting layer, a magnetic layer, an anti-puncture layer, a second cutting layer and a ring frame, wherein the first cutting layer, the magnetic layer, the anti-puncture layer and the second cutting layer are respectively sheet-shaped structures, and the first cutting layer, the magnetic layer, the anti-puncture layer and the second cutting layer are arranged in sequence along the thickness direction thereof, and the ring frame is a frame-shaped structure, the ring frame surrounds the lateral periphery of the magnetic layer, and the ring frame is located between the first cutting layer and the anti-puncture layer, thereby covering and positioning the magnetic layer;

The first cutting layer and the second cutting layer are respectively made of soft thermoplastic resin, the anti-puncture layer is made of hard thermoplastic resin, the ring frame is made of thermoplastic resin, the magnetic attraction layer is made of a magnetic sheet with magnetic attraction force, and the first cutting layer, the ring frame, the anti-puncture layer and the second cutting layer are integrally heat-melted and pressed.

The magnetic layer will not move arbitrarily, and the magnetic layer will not be exposed to affect the service life or cause harm to the safety of use.

Another purpose of the invention is to replace the magnetic layer with a magnetically attracted magnetic layer, so as to utilize a magnetic object with magnetic force to magnetically attract the magnetic layer, thereby positioning the object to be cut.

The drawings show an embodiment of the cutting pad for facilitating the work of the present invention, but these embodiments are for illustrative purposes only and are not limited to this structure in patent applications.

As shown in FIGS. 1 to 3 , the first embodiment of the cutting pad for facilitating work includes a first cutting layer 10, a magnetic layer 20, an anti-puncture layer 30, a second cutting layer 40 and a ring frame 50, wherein the first cutting layer 10, the magnetic layer 20, the anti-puncture layer 30 and the second cutting layer 40 are sheet-like structures, and the The first cutting layer 10, the magnetic layer 20, the anti-puncture layer 30 and the second cutting layer 40 are arranged in sequence along the thickness direction thereof. The annular frame 50 is a frame-shaped structure. The annular frame 50 surrounds the lateral periphery of the magnetic layer 20 and is located between the first cutting layer 10 and the anti-puncture layer 30, thereby covering and positioning the magnetic layer 20.

The first cutting layer 10 and the second cutting layer 40 are respectively made of soft thermoplastic resin, providing cutting entry for the tool and absorbing and buffering the cutting effect of the tool. The anti-puncture layer 30 is made of hard thermoplastic resin. The ring frame 50 can be selectively made of hard thermoplastic resin or soft thermoplastic resin. The magnetic layer 20 is made of a magnetic sheet with magnetic adsorption force, so that the magnetically attracted object 92 made of magnetically conductive material can be adsorbed by the magnetic layer 20. The first cutting layer 10, the ring frame 50, the anti-puncture layer 30 and the second cutting layer 40 are integrally heat-melted and pressed.

The first embodiment may further include two surface layers 60 as needed, wherein each surface layer 60 is a sheet made of soft thermoplastic resin, and each surface layer 60 is respectively combined with one side of the first cutting layer 10 and the second cutting layer 40 in the thickness direction, thereby respectively constituting surfaces 62 of the cutting pad 01 that are opposite to each other in the thickness direction.

When the first embodiment is manufactured, the first cutting layer 10, the magnetic layer 20, the anti-puncture layer 30, the second cutting layer 40, the ring frame 50 and each of the surface layers 60 are stacked in sequence to form a semi-finished product with a multi-layer structure (not shown in the figure), and then the semi-finished product is subjected to high-temperature hot melting and pressing to make the first cutting layer 10, the anti-puncture layer 30, the second cutting layer 40, the ring frame 50 and each of the surface layers 60 hot-melt bonded, thereby manufacturing the first embodiment of the layered structure, and then, if necessary, the first embodiment is cut to form a predetermined shape and size on the lateral periphery of the first embodiment.

When using a knife to cut a flat and thin object 94 such as paper, cloth, or leather, the first embodiment is placed under the object 94, and one of the surfaces 62 is facing upward to contact the object 94, and the other surface 62 is facing downward to contact a workbench (not shown) where the cutting operation is performed, and the anti-puncture layer 30 is located above the magnetic layer 20, and the second cutting layer 40 made of a soft thermoplastic resin is used to provide a cutting surface for the object 94. 4, the blade can penetrate the article 94 in the thickness direction of the article 94, the second cutting layer 40 absorbs the force of the blade, and forms a buffering effect for the blade to further penetrate into the magnetic layer 20, and the anti-puncture layer 30 composed of hard thermoplastic resin forms a barrier to the blade, and the blade cannot further penetrate into the first embodiment, thereby preventing the blade from contacting or damaging the magnetic layer 20.

When cutting the object 94, one to several magnetically attracted objects 92 may be placed on the top edge surface of the object 94. The specific example of the magnetically attracted object 92 is not limited to that shown in FIG. 3. The magnetic force generated by the magnetic layer 20 acts on the magnetically attracted object 92, so that the magnetically attracted object 92 presses the object 94, and the object 94 is not easy to slide, thereby providing convenience for the cutting operation.

The cutting pad 01 is integrally formed by high-temperature hot-melt pressing, so that moisture in the air cannot penetrate into the interior of the cutting pad 01, and changes in temperature and humidity are not likely to cause the adjacent magnetic layer 20 and the adjacent first cutting layer 10 and the anti-puncture layer 30 to peel off from each other. The ring frame 50 surrounds the magnetic layer 20, which can prevent the edge of the thin magnetic layer 20 from protruding from the outside of the cutting pad 01, thereby preventing the magnetic layer 20 from cutting the user and causing no harm to the safety of use.

An annular gap 72 is formed between the lateral periphery of the magnetic layer 20 and the ring frame 50, and the first cutting layer 10 and the anti-puncture layer 30 are respectively filled in the gap 72; the width of the gap 72 between the magnetic layer 20 and the ring frame 50 is selected to be between 0.3 mm and 2 mm.

The formation of the gap 72 makes it easy for the magnetic layer 20 to be assembled into the annular inner edge of the ring frame 50. When high-temperature hot melt pressing is subsequently performed, the first cutting layer 10 and the anti-puncture layer 30 are heated and softened to fill the gap 72. After the cutting pad 01 is manufactured, the magnetic layer 20 will not move laterally inside the cutting pad 01.

As shown in FIG4 , the main difference between the second embodiment and the first embodiment is that the magnetic layer 20 of the first embodiment is replaced by a magnetic conductive layer 80, wherein the magnetic conductive layer 80 is a thin structure made of a magnetic conductive material that can be magnetically attracted, and the magnetic conductive layer 80 is made of a metal plate, so that a magnetic object (not shown) with magnetic force can magnetically attract the magnetic conductive layer 80, so that the magnetic object cooperates with the surface layer 60 to relatively clamp and position the cut object 94.

As shown in FIG. 5 , the structure of the third embodiment is mainly different from that of the first embodiment in that the third embodiment includes two magnetic attraction layers 20 and two ring frames 50 respectively surrounding each of the magnetic attraction layers 20 , and each of the ring frames 50 is arranged side by side.

The third embodiment is based on the two magnetic layers 20 arranged side by side and the two ring frames 50 respectively surrounding the magnetic layers 20, and a folding structure (not shown) may be further configured, and the folding structure is located between the ring frames 50, so that the third embodiment can be folded, which is convenient for storage and carrying. The folding structure is an existing technology that can be thought of by people in the relevant technical field, and the specific structure of the folding structure will not be described in detail.

FIG. 6 and FIG. 7 respectively show the fourth and fifth embodiments based on the variation of the third embodiment. The fourth and fifth embodiments respectively include four magnetic attraction layers 20 and four ring frames 50 corresponding to each magnetic attraction layer 20. The main difference between the fourth and fifth embodiments is that the configuration of the magnetic attraction layers 20 is different.

The magnetic attraction layers 20 of the third to fifth embodiments can be respectively replaced by the magnetic conductive layer 80 disclosed in the second embodiment, thereby constituting a plurality of replacement implementation options of the present invention.
