It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This utility model discloses a specific implementation method for a profile cutting device that prevents waste from being caught. Please see [link / reference]. Figure 1As shown in the figure, the cutting device includes a base frame 1, which is equipped with a first sawing mechanism 2 and a second sawing mechanism 3 arranged along the material conveying direction. The first sawing mechanism 2 is mainly used for cutting profiles at a 45-degree angle, while the second sawing mechanism 3 is mainly used for multi-angle cutting, which is mainly achieved by a rotating mechanism.

[0020] Combination Figure 2 and Figure 3 The first sawing mechanism 2 includes a first saw blade 210, a first sawing motor 209 that drives the first saw blade 210 to rotate, a first lifting mechanism that drives the first sawing mechanism to move in the height direction, and a first horizontal moving mechanism that drives the first sawing motor 209 to move in the horizontal direction. The first sawing mechanism 2 includes a first base plate 201 fixedly mounted on a base frame 1. A vertically arranged first mounting plate 202 is fixedly mounted on the first base plate 201. A first vertical slide rail 203 is fixedly mounted on the first mounting plate 202. The first vertical slide rail 203 is provided with a first vertical slider 204 that slides with it. A first slide table 205 for mounting the first sawing motor 209 is fixedly connected to the first vertical slider 204.

[0021] In this embodiment, a first horizontal slide rail 206 is fixedly installed on the top surface of the first slide table 205. The first horizontal slide rail 206 is provided with a first horizontal slider 207 that slides with it. A second slide table 208 is fixedly connected to the top surface of the first horizontal slider 207. A first sawing motor 209 is fixedly installed on the second slide table 208, and the output shaft of the first sawing motor 209 is fixedly connected to the first saw blade 210. The first horizontal moving mechanism includes a first horizontal cylinder 211 fixedly installed at the bottom of the first slide table 205. The telescopic rod of the first horizontal cylinder 211 is fixedly connected to the second slide table 208 through a connector 212, so that the first horizontal cylinder 211 drives the second slide table 208 to slide along the first horizontal slide rail 206. The first lifting mechanism includes a first vertical motor 213 fixedly mounted on a first mounting plate 202. A first vertical lead screw 215 rotatable relative to the first mounting plate 202 is provided on the side of the first vertical motor 213. The output shaft of the first vertical motor 213 is connected to the first vertical lead screw 215 via a pulley assembly 214. A first lead screw nut 216 that can slide along the first vertical lead screw 215 is sleeved on the outside of the first vertical lead screw 215. The first lead screw nut 216 is fixedly connected to the first slide table 205 so that the first vertical motor 213 drives the first slide table 205 to move in the vertical direction.

[0022] The working process of the first sawing mechanism 2 in this embodiment is as follows: First, cutting is started by the first sawing motor 209 driving the first saw blade 210 to rotate for cutting the profile. Then, the profile is cut by moving in the vertical direction. The first vertical motor 213 (fixed on the first mounting plate 202) is energized and started, and its output shaft rotates. The output shaft of the first vertical motor 213 transmits the rotational power to the first vertical lead screw 215 through the pulley assembly 214 (such as a belt and pulley). The first vertical lead screw 215 can rotate relative to the first mounting plate 202, but the lead screw itself does not move. When the first vertical lead screw 215 rotates, the first lead screw nut 216 (fixed to the first slide table 205) is forced to slide up and down along the thread direction of the first vertical lead screw 215, thereby driving the first slide table 205 (the first sawing motor 209 is located on the first slide table 205) to move in the vertical direction. After cutting, the first saw blade 210 moves horizontally to achieve lateral feeding or avoidance. The first horizontal cylinder 211 (fixedly installed at the bottom of the second slide 208) is activated, and its telescopic rod extends or retracts. Since the cylinder body of the first horizontal cylinder 211 is fixed to the first slide 205 (fixed part), and the telescopic rod is fixed to the second slide 208 (moving part) through the connector 212, when the first horizontal cylinder 211 is activated, the linear movement of the telescopic rod can push the second slide 208 to move, thereby directly driving the first sawing motor 209 and the saw blade to move horizontally, so as to avoid scrap.

[0023] Combination Figure 4 and Figure 5 The second sawing mechanism 3 includes a second saw blade 312, a second sawing motor 311 that drives the second saw blade 312 to rotate, a second lifting mechanism that drives the second sawing mechanism to move in the height direction, and a second horizontal moving mechanism that drives the second sawing motor 311 to move in the horizontal direction. The second sawing mechanism 3 includes a gantry frame 301 fixedly mounted on the base frame 1. A second horizontal slide rail 302 is fixedly mounted on the top surface of the gantry frame 301. The second horizontal slide rail 302 is provided with a second horizontal slider 303 that slides with it. A third slide table 304 is fixedly mounted on the top surface of the second horizontal slider 303.

[0024] In this embodiment, the second horizontal moving mechanism includes a second horizontal cylinder 305 fixedly installed on the gantry 301. The telescopic rod of the second horizontal cylinder 305 is fixedly connected to the third slide 304 so that the second horizontal cylinder 305 drives the third slide 304 to slide in the horizontal direction.

[0025] In this embodiment, a second mounting plate 306 is fixedly installed on the third slide table 304, and a second vertical slide rail 307 is fixedly installed on the side of the second mounting plate 306. The second vertical slide rail 307 is provided with a second vertical slider 308 that slides with it. The second vertical slider 308 is fixedly connected to a rotating bracket 309. A rotary motor 310 is fixedly installed inside the rotating bracket 309. A second sawing motor 311 is fixedly connected to the output end of the rotary motor 310. The output shaft of the second sawing motor 311 is fixedly connected to the second saw blade 312.

[0026] In this embodiment, the second lifting mechanism includes a second vertical motor 313 fixedly mounted on the second mounting plate 306. The output shaft of the second vertical motor 313 is fixedly connected to a second vertical lead screw 314. A second lead screw nut that can slide along the second vertical lead screw 314 is sleeved on the outside of the second vertical lead screw 314. The second lead screw nut is fixedly connected to the rotating bracket 309 so that the second vertical motor 313 drives the second sawing motor 311 to slide in the vertical direction.

[0027] The working process of the second sawing mechanism 3 in this embodiment is as follows: First, cutting is started by the second sawing motor 311 driving the second saw blade 312 to rotate for cutting the profile. Then, the profile is cut by moving in the vertical direction. The second vertical motor 313 (fixed on the second mounting plate 306) is energized and started, and its output shaft rotates. The output shaft of the second vertical motor 313 drives the second vertical lead screw 314 to rotate. The second vertical lead screw 314 can rotate relative to the second mounting plate 306, but the lead screw itself does not move. When the second vertical lead screw 314 rotates, the second lead screw nut (fixed to the rotating bracket 309) is forced to slide up and down along the thread direction of the second vertical lead screw 314, thereby driving the rotating bracket 309 (the second sawing motor 311 is located on the rotating bracket 309) to move in the vertical direction to cut the profile. After cutting is completed, the second saw blade 312 moves in the horizontal direction to realize the lateral feed or avoidance of the saw blade. The second horizontal cylinder 305 (fixedly mounted on the gantry 301, which is fixed relative to the base frame 1) extends or retracts its telescopic rod. Since the cylinder body of the second horizontal cylinder 305 is fixed to the gantry 301, and the telescopic rod is fixedly connected to the third slide 304, when the second horizontal cylinder 305 is activated, the linear movement of the telescopic rod can push the third slide 304 to move, thereby directly driving the second sawing motor 311 and the second saw blade 312 to move horizontally, thus avoiding scrap. Additionally, a rotary motor 310 is mounted on the rotating bracket 309. The output end of the rotary motor 310 is fixedly connected to the body of the second sawing motor 311. Therefore, the rotary motor 310 can drive the second sawing motor 311 to rotate at any angle, thereby achieving multi-angle cutting and improving the applicability of the cutting device.

[0028] Compared with the prior art, the cutting device of this embodiment drives the first saw blade 210 and the second saw blade 312 to move in the horizontal direction by setting the first horizontal moving mechanism and the second horizontal moving mechanism respectively. After the saw blade completes the cutting of the profile, the saw blade moves horizontally first to separate the saw blade from the saw cut surface of the profile. Then the saw blade returns to its original position by moving up and down, avoiding friction between the saw blade and the profile or waste material during the return process, thus solving the problem of waste material sticking in the past.

[0029] Finally, it should be noted that the anti-snagging waste profile cutting device disclosed in this utility model embodiment is only a preferred embodiment of this utility model and is only used to illustrate the technical solution of this utility model, not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
