[0033] The embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art will recognize that the described embodiments can be modified in various ways or combinations thereof without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims. Furthermore, in this specification, the drawings are not drawn to scale, and the same reference numerals denote the same parts.

[0034] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Rotary connection" refers to a connection where the components can rotate relative to each other after connection. The directional terms mentioned in the embodiments of this application, such as "upper," "lower," "inner," and "outer," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. The phrase "two components obtain an integrated structure through an integral molding process" means that during the formation of one of the two components, that component is connected to the other component, without requiring further processing (such as bonding, welding, snap-fit ​​connection, or screw connection) to connect the two components together.

[0035] The circular cutting tool in this embodiment uses a circular cutter and a circular through-hole to cut out the required circular film. This method results in a neat outline and minimal dimensional error in the circular film, thereby reducing material waste.

[0036] like Figure 1 As shown, the circular cutting tool of this embodiment includes a cover plate 1, which is a flat plate for mounting a ring cutter 2; the ring cutter 2 is fixedly connected to the cover plate 1 and is used to cooperate with the first circular through hole 4 to cut a circular geomembrane; a base 3 is rotatably connected to the cover plate 1 via a hinge, thereby allowing it to open and close; the first circular through hole 4 is provided on the base 3 and penetrates the base 3. This geomembrane circular cutting tool can be made of steel.

[0037] A ring cutter 2 is fixedly connected to the inner side of the cover plate 1, that is, the side opposite to the base 3. One end of the cover plate 1 is rotatably connected to the base 3 via a hinge 5. Figure 1When the cover plate 1 is rotated clockwise, it is buckled on the base 3, and when the cover plate 1 is rotated anticlockwise, it is away from the base.

[0038] The ring cutter 2 is a thin-walled ring, one end of which is fixedly connected to the inner side of the cover plate 1, and the other end of which has a ring-shaped cutting edge for cutting the geomembrane.

[0039] A first circular hole 4 is arranged on the base 3, the position of the first circular hole 4 should correspond to the position of the ring cutter 2, and the diameter of the first circular hole 4 is equivalent to the outer diameter of the ring cutter 2 and equal to the diameter of the required circular material film. When the ring cutter 2 falls, it extrudes the geomembrane from both sides of the first circular hole 4, thereby cutting the required circular material film.

[0040] Of course, the outer diameter of the ring cutter 2 can be slightly smaller than the diameter of the first circular hole 4 to facilitate cutting by the ring cutter. For example, if the diameter of the circular material film is required to be 300 mm, the diameter of the first circular hole 4 can be 300 mm, and the outer diameter of the ring cutter 2 is 299 mm. The geomembrane is covered on the base 3 so that the geomembrane covers the first circular hole 4. When the cover plate 1 is buckled on the base 3, the ring cutter 2 gradually approaches the first circular hole, the ring-shaped cutting edge of the ring cutter 2 contacts the geomembrane, and when the cover plate 1 is buckled on the base 3, the ring-shaped cutting edge of the ring cutter 2 cooperates with the first circular hole to cut the geomembrane, similar to scissors cutting the geomembrane, thereby cutting the geomembrane into a circular profile as a circular material film.

[0041] In some embodiments, a handle 6 is further arranged on the cover plate 1, which can be integrally formed with the cover plate 1 or installed on the cover plate 1 by welding, threading, rivet connection or the like. The handle is preferably circular and has anti-slip lines to facilitate more stable holding of the cover plate. The cover plate is driven to rotate by holding the handle 6, which can better control the cutting.

[0042] In some embodiments, as shown in Figure 2 the other end of the ring cutter 2 also has sawteeth 7, which can be arranged in a circle along the circumference of the ring cutter 2, Figure 2 only a few sawteeth are exemplarily shown. When the cover plate 1 is buckled on the base 3, the ring cutter 2 gradually approaches the first circular hole, the sawteeth of the ring cutter 2 contact the geomembrane, and when the cover plate 1 is buckled on the base 3, the sawteeth of the ring cutter 2 cooperate with the first circular hole to cut the geomembrane, similar to scissors cutting the geomembrane, thereby cutting the geomembrane into a circular profile as a circular material film. In order to maintain the cutting effect, the tooth edges of the sawteeth 7 also have cutting edges, as shown in Figure 2In the embodiment, the sawtooth 7 is triangular, both sides of the triangle have cutting edges, so that the sawtooth can pierce into the geomembrane through the tip of the triangular sawtooth, and cut the geomembrane through the cutting edges of both sides, and the circular material film can be cut more efficiently.

[0043] In some embodiments, the ring cutter 2 is detachably connected, such as Figure 3 In the embodiment, the ring cutter can extend a first mounting plate 21 around the circumference, and the first mounting plate 21 is provided with a first mounting hole 22 for passing through a bolt, and the cover plate 1 is correspondingly provided with a first threaded hole, and the ring cutter is mounted on the inner side of the cover plate 1 by passing the bolt through the first mounting hole and screwing it on the first threaded hole. The size of the ring cutter 2 can be selected according to the size of the circular material film, for example, a ring cutter with an outer diameter of 200mm, and a ring cutter with an outer diameter of 300mm can be installed on the cover plate 1 by a bolt, which can be used to cut circular material films of different diameters.

[0044] Correspondingly, in order to cooperate with ring cutters 2 of different sizes, the base 3 can also be provided with hole plates 8 of different sizes, and the hole plates 8 can be further provided with second circular through holes 83, and the hole plates 8 are fixedly connected with second mounting plates 81 around the circumference, and the second mounting plates 81 are provided with second mounting holes 82 for passing through a bolt, and the base 3 is correspondingly provided with second threaded holes, and the hole plates 8 are mounted on the base 3 by passing the bolt through the second mounting hole 82 and screwing it on the second threaded hole. The diameter of the second circular through hole 83 is smaller than the diameter of the first circular through hole 4.

[0045] The hole plate 8 and the ring cutter 2 can have suitable matching sizes, for example, the diameter of the circular material film is required to be 100mm, and the hole plate 8 is installed on the base 3, and the diameter of the second circular through hole 83 on the hole plate 8 can be 100mm. Similarly, the ring cutter 2 is installed on the inner side of the cover plate 1, and the outer diameter of the ring cutter 2 is 100mm. The geomembrane is covered on the hole plate 8, so that the geomembrane covers the second circular through hole 83. When the cover plate 1 is buckled to the base 3, the ring cutter 2 gradually approaches the second circular through hole 83, the cutting edge of the ring cutter 2 contacts the geomembrane, and when the cover plate 1 is buckled to the base 3, the cutting edge of the ring cutter 2 cooperates with the second circular through hole to cut the geomembrane, which is similar to a pair of scissors cutting the geomembrane, and the geomembrane is cut into a circular profile as a circular material film.

[0046] For example, if the diameter of the circular geomembrane is required to be 200mm, a hole plate 8 is installed on the base 3, and the diameter of the second circular through hole 83 on the hole plate 8 can be 200mm. Similarly, a ring cutter 2 is installed on the inner side of the cover plate 1, and the outer diameter of the ring cutter 2 is 200mm. The geomembrane is covered on the hole plate 8, so that the geomembrane covers the second circular through hole 83. When the cover plate 1 is buckled to the base 3, the ring cutter 2 gradually approaches the second circular through hole 83, the cutting edge of the ring cutter 2 contacts the geomembrane, and when the cover plate 1 is buckled to the base 3, the cutting edge of the ring cutter 2 cooperates with the second circular through hole to cut the geomembrane, similar to scissors cutting the geomembrane, and the geomembrane is cut into a circular profile as a circular geomembrane. It can be seen that by installing different ring cutters and hole plates, circular geomembranes with different diameters can be made.

[0047] It should be noted that, in order to facilitate the smooth cutting of the ring cutter and the circular through hole, the outer diameter of the ring cutter can be set to be slightly smaller than the diameter of the circular geomembrane, and the circular through hole can be set to be slightly larger than the diameter of the circular geomembrane. Thus, the ring cutter and the circular through hole can have a relatively smooth cutting stroke.

[0048] The above only describes the preferred embodiments of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
