DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Various aspects and features of the present invention are described herein with reference to the accompanying drawings.

[0026] These and other characteristics of the invention will become apparent from the following description of a preferred form of embodiment given as a non-limiting example, with reference to the accompanying drawings.

[0027] It should also be understood that, although the invention has been described with reference to some specific examples, those skilled in the art will be able to realize many other equivalent forms of the invention that have the characteristics recited in the claims and are therefore within the scope of protection defined thereby.

[0028] The above and other aspects, features and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown, an extruded board cutting device provided by an embodiment of the present invention comprises a first support 1 and a second support 2 arranged opposite to each other, wherein the first support 1 comprises a first seat body 11 and a first column 12 arranged on the first seat body 11, and the second support 2 comprises a second seat body 21 and a second column 22 arranged on the second seat body 21, a cutting blade 3 which can be bent into an arc shape is arranged horizontally and slidably between the first column 12 and the second column 22, and an arc adjustment mechanism 4 for adjusting the bending arc of the cutting blade 3 is arranged between the first support 1 and the second support 2. In the present invention, the cutting blade 3 can actually be a steel blade which can be bent into a certain arc. The spacing between the first support 1 and the second support 2 must at least be set to match the common width size of the extruded board on the market, for example, it can be 600mm or 1000mm (the two sides can be appropriately widened by 100mm). In addition, the first support 1 and the second support 2 are also preferably made of steel material, and rollers 111 and 211 can be preferably added to the first support body 11 and the second support body to facilitate on-site transportation. Figure 1 and Figure 2 As shown, the curvature adjustment mechanism 4 includes a first adjustment arm 41 and a second adjustment arm 42 which are arranged at an angle to each other, and one end of the first adjustment arm 41 and the second adjustment arm 42 are respectively connected to the first seat body 11 and the second seat body 21, and are fixedly connected at an adjustable angle near the other end thereof by a fixing member 43. The fixing member 43 can lock the distance and relative angle between the first adjustment arm 41 and the second adjustment arm 42 after the first adjustment arm 41 and the second adjustment arm 42 are bent to a suitable curvature after matching the cutting blade 3. In the process of matching the curvature, the components are in a relaxed state here to ensure that they can slide freely and adjust the angle freely. More specifically, in some embodiments, such as Figure 1As shown, the first adjusting arm 41 and the second adjusting arm 42 are respectively provided with a plurality of locating grooves at equal intervals, such as the locating groove 411 provided on the first adjusting arm 41 and the locating groove 421 provided on the second adjusting arm 42, and the fixing member 43 is a fixing bolt that can pass through the locating grooves on the first adjusting arm 41 and the second adjusting arm 42 respectively. When in use, the fixing bolt can be released, and then the cutting blade 3 is adjusted to a suitable height and curvature, and then the first adjusting arm 41 and the second adjusting arm 42 intersect, and then the fixing member 43 is passed through the locating groove at the intersection, and the bolt is tightened to fix. At this time, since the angle between the first adjusting arm 41 and the second adjusting arm 42 has been fixed, the curvature of the cutting blade 3 is also fixed. Next, the extruded board to be cut can be placed below the cutting blade 3, and then the cutting blade 3 is released downwards, so that the extruded board (not shown in the figure) can be accurately cut into the required arc.

[0030] More specifically, in the present invention, the cutting blade 3 is located between the first support 1 and the second support 2. When cutting, it needs to slide up and down. Therefore, in some specific applications, the first column 12 and the second column 22 include two clamps arranged opposite to each other, such as clamp 121 and clamp 221. A first slide groove is constructed between the two clamps, namely the first slide groove 122 and the first slide groove 222. The first slide groove is penetrated by a first adjustment bolt 5 for adjusting the distance between the two clamps to clamp / release the cutting blade 3. In the non-working state, the first adjustment bolt 5 can be tightened to reduce the distance between the first slide grooves, and the cutting blade 3 is clamped and fixed. When the cutting blade 3 needs to be operated, the first adjustment bolt 5 can be released. In addition, if Figure 2 As shown, a gasket 123 may also be provided in the first chute 122, and the cutting blade 3 is provided in the first chute 122 through the gasket 123. In addition to ensuring the fixation of the two packages, the gasket 123 may also be provided with a second adjustment bolt 6 for adjusting the horizontal position of the gasket 123 in the first chute 122 on the first column 12 and the second column 22. The second adjustment bolt 6 may make the position of the gasket 123 in the first chute 122 adjustable, thereby adjusting the effective cutting length of the cutting blade 3.

[0031] Figures 3 to 5A structural schematic diagram of a second embodiment of the curvature adjustment mechanism of the cutting device of the extruded board of the present invention is shown. As shown in the figure, the curvature adjustment mechanism 4 includes a first adjusting arm 401 and a second adjusting arm 402 arranged at an angle to each other, the first adjusting arm 401 is provided with a second slide groove 4011 along its length direction, and a second slider 406 is provided in the second slide groove 4011, one end of the first adjusting arm 401 and the second adjusting arm 402 are respectively connected to the first seat body 11 and the second seat body 21, and are fixedly connected at an adjustable angle by a fixing member 403 near the other end thereof, and a second fixing nut 4061 is constructed on the second slider 406, and the fixing member 403 is a bolt member that penetrates the second adjusting arm 402 and the second fixing nut 4061 to fix the second slider 406 and / or the first adjusting arm 401. When the second slider 406 is fixed alone, the second slider can move in the second slide groove 4011, so that the cutting blade 3 can be shaped into a regular arc or an irregular arc, that is, when the fixing member 403 is located at the vertex of a minor arc of the circular trajectory, the second slider 406 and the first adjustment arm 401 are fixed at the same time, and when the cutting blade 3 is required to be an arc similar to a spiral expansion, it can be achieved by only making the second slider 406 movable in the second slide groove 4011. In this embodiment, preferably, a first slider 405 is also provided in the second slide groove 4011, and an arc plate 4022 for indicating the arc is provided on the second adjustment arm 402. One end of the first slider 405 is constructed with a protrusion 4051, and the other end is provided with a stud 4052, and the arc plate 4022 is located between the protrusion 4051 and the stud 4052. Figure 3 As shown, the arc plate 4022 is provided with an angle indicating portion for indicating the angle, and the protruding portion 4051 is provided with a through slot 40511 for observing the angle value. Compared with the previous embodiment, this embodiment can achieve more accurate arc adjustment.

[0032] In addition, if Figure 5 As shown, a first fixing nut 404 is connected to the stud 4052 for auxiliary fixing of the position of the arc plate 4022. The cutting blade can be kept at a suitable arc through the dual fixing of the first fixing nut 404 and the fixing member 403. Furthermore, in this embodiment, the second adjustment arm 402 may specifically include a body 4021 and an arc plate 4022 connected to the body 4021, and a bayonet 4023 may be provided on the inner side of the intersection of the arc plate 4022 and the body 4021, and the bayonet is adapted to the stud 4052.

[0033] The difference between the two embodiments listed above is that the first embodiment is suitable for cutting with low precision, while the second embodiment is suitable for precise arc cutting and can be applied to irregular arcs. However, the same thing between the two is that the first adjustment arm and the second adjustment arm are arranged on the first seat body and the second seat body at positions tangent to the arc formed by the cutting blade 3.
