[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This utility model is equipped with a lifting mechanism, a limiting mechanism, a moving mechanism, a cutting mechanism, and a holding mechanism. When cutting parallel flow zinc-aluminum sprayed flat tubes, the limiting mechanism first limits the front and rear sides of the tube to prevent it from moving back and forth, thus preventing it from tilting during the cutting process.

Under the action of the holding mechanism, the tube is held and fixed, making it more stable during cutting and improving the cutting effect, resulting in a flatter tube after cutting. Finally, the cutting mechanism, in cooperation with the moving mechanism, cuts the tube to the required length, making the operation convenient and reducing labor intensity.

[0025] Reference Appendix Figure 1-6 The present invention provides a parallel flow zinc-aluminum sprayed flat tube cutting machine. The parallel flow zinc-aluminum sprayed flat tube cutting machine includes a worktable 1. A lifting mechanism 3 and a limiting mechanism 2 are provided at the upper end of the worktable 1. The limiting mechanism 2 is located to the left of the lifting mechanism 3. A moving mechanism 4 is provided inside the lifting mechanism 3. A cutting mechanism 5 is provided at the lower end of the moving mechanism 4. Holding mechanisms 6 are provided on both the left and right sides of the lifting mechanism 3. The holding mechanisms 6 are used to hold and fix the parallel flow zinc-aluminum sprayed flat tube.

[0026] Specifically, the parallel flow zinc-aluminum sprayed flat tube to be cut is placed on the workbench 1. First, the front and rear sides of the parallel flow zinc-aluminum sprayed flat tube are restricted by the limiting mechanism 2 to prevent the tube from moving back and forth, thereby preventing the tube from tilting during the cutting process. Then, the lifting mechanism 3 operates, driving the cutting mechanism 5 and the holding mechanism 6 to move downward. Under the action of the holding mechanism 6, the parallel flow zinc-aluminum sprayed flat tube can be pressed and fixed, making the tube more stable during cutting and improving the cutting effect, resulting in a flatter tube after cutting. Next, the cutting mechanism 5 operates, and with the cooperation of the moving mechanism 4, the parallel flow zinc-aluminum sprayed flat tube can be cut into the required length. The operation is convenient and reduces labor intensity.

[0027] The limiting mechanism 2 includes a first bearing seat 201, a first motor 202, a bidirectional threaded rod 203, a threaded block 204, a limiting seat 205, and a roller 206. The first bearing seat 201 is fixedly connected to both the front and rear sides of the lower end of the worktable 1. The bidirectional threaded rod 203 is rotatably connected inside the first bearing seat 201. The threaded block 204 is threadedly connected to the circumferential surface of the bidirectional threaded rod 203. The threaded block 204 is slidably connected to the worktable 1. There are two threaded blocks 204, which are symmetrically distributed on the bidirectional threaded rod 203. The internal threads of the two threaded blocks 204 have opposite directions. The limiting seat 205 is fixedly connected to the upper end of the threaded block 204. The roller 206 is rotatably connected inside the limiting seat 205. A first motor 202 is fixedly connected to the lower end of the workbench 1. The output end of the first motor 202 is fixedly connected to the bidirectional threaded rod 203. When the first motor 202 is working, the output end of the first motor 202, in cooperation with the bidirectional threaded rod 203, drives the threaded block 204 to slide inside the workbench 1, thereby driving the limiting seat 205 to move. When the two limiting seats 205 move towards each other, they drive the roller 206 to approach the parallel flow zinc-aluminum sprayed flat tube. When both the front and rear sides of the parallel flow zinc-aluminum sprayed flat tube are in contact with the roller 206, the parallel flow zinc-aluminum sprayed flat tube is limited, preventing it from moving back and forth. At the same time, with the cooperation of the roller 206, the parallel flow zinc-aluminum sprayed flat tube can move left and right.

[0028] The lifting mechanism 3 includes a support frame 301, an electric telescopic rod 302, a first guide rod 303, and a moving frame 304. The support frame 301 is fixedly connected to the upper end of the worktable 1. The electric telescopic rod 302 is fixedly connected to the upper end of the support frame 301. The extended end of the electric telescopic rod 302 passes through the support frame 301 and is slidably connected to the support frame 301. The moving frame 304 is fixedly connected to the extended end of the electric telescopic rod 302. The first guide rod 303 is fixedly connected to the upper end of the moving frame 304. The first guide rod 303 is slidably connected to the support frame 301. During operation, the electric telescopic rod 302 extends and, with the cooperation of the first guide rod 303, drives the moving frame 304 to move down stably, thereby driving the cutting mechanism 5 and the pressing mechanism to move down, so that the cutting mechanism 5 cuts the parallel flow zinc-aluminum flat tube.

[0029] The moving mechanism 4 includes a second motor 401, a lead screw 402, a moving seat 403, and a slide rail 404. The lead screw 402 is rotatably connected inside the moving frame 304, and the moving seat 403 is threadedly connected to the circumferential surface of the lead screw 402. The slide rail 404 is fixedly connected inside the moving frame 304, and the slide rail 404 and the moving seat 403 are slidably connected. The second motor 401 is fixedly connected to the rear end of the moving frame 304. The output end of the second motor 401 is fixedly connected to the lead screw 402. When the second motor 401 is working, the output end of the second motor 401 drives the moving seat 403 to slide on the slide rail 404 under the action of the lead screw 402, thereby driving the cutting mechanism 5 to move back and forth, and thus cutting the parallel flow zinc-aluminum flat tube.

[0030] The cutting mechanism 5 includes a third motor 501, a cutting blade 502, and a second bearing seat 503. The lower end of the movable seat 403 is fixedly connected to the third motor 501 and the bearing seat. The output end of the third motor 501 passes through the second bearing seat 503 and is rotatably connected to it. The output end of the third motor 501 is fixedly connected to the cutting blade 502. When the third motor 501 is working, the output end of the third motor 501 drives the cutting blade 502 to rotate. With the rotation of the cutting blade 502, the parallel flow sprayed zinc-aluminum flat tube can be cut with the cooperation of the movable mechanism 4.

[0031] The holding mechanism 6 includes a fixed plate 601, a second guide rod 602, a pressure plate 603, and a spring 604. Fixed plates 601 are fixedly connected to both the left and right sides of the movable frame 304. The second guide rod 602 is slidably connected inside the fixed plate 601. The lower end of the second guide rod 602 is fixedly connected to the pressure plate 603. A spring 604 is provided on the circumferential surface of the second guide rod 602. One end of the spring 604 is fixedly connected to the pressure plate 603, and the other end of the spring 604 is fixedly connected to the fixed plate 601. Next, during operation, as the moving frame 304 moves downward, when the pressure plate 603 contacts the parallel flow zinc-aluminum sprayed flat tube, it will squeeze the second guide rod 602 to move upward, thereby compressing the spring 604. The compressed spring 604, under the reaction force, can make the pressure plate 603 stably hold the parallel flow zinc-aluminum sprayed flat tube, making the parallel flow zinc-aluminum sprayed flat tube more stable during cutting, improving the cutting effect of the parallel flow zinc-aluminum sprayed flat tube, and making the cut parallel flow zinc-aluminum sprayed flat tube flatter.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
