[0022] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0023] Reference Figure 1-Figure 3As shown, the fin cutting machine with adjustable cutting angle of this embodiment includes a frame 1 and a driving mechanism and a cutting table 2 arranged on the frame 1. The cutting table 2 is arranged on the frame 1 so as to be liftable. The driving mechanism is connected to the cutting table 2 to drive the cutting table 2 to be lifted or lowered. A propulsion mechanism 4 is provided on the frame 1, and the propulsion mechanism 4 is arranged adjacent to the cutting table 2. A cutting knife 3 is provided on the lower side of the cutting table 2, and the upper end of the cutting knife 3 is rotatably connected to the cutting table 2. Slide grooves 21 are provided on both sides of the cutting table 2, and a locking rod 22 is slidably connected in the slide groove 21. A locking groove 221 is provided on the side of the locking rod 22 facing the cutting knife 3, and a locking hole 23 is provided on the side of the slide groove 21. A locking column 231 is threadedly connected to the locking hole 23, and the locking column 231 conflicts with the locking rod 22.

[0024] Through the above technical solution, the continuous fins output by the fin forming machine are transmitted between the cutting table 2 and the frame 1 through the propulsion mechanism 4. When cutting, the driving mechanism drives the cutting table 2 to descend, and the cutting table 2 descends to drive the cutting knife 3 to descend, and then cut the continuous fins below into fin parts.

[0025] The process of adjusting the angle of the cutting knife 3 is as follows: first rotate the locking column 231 so that the locking columns 231 on both sides move away from the cutting knife 3, then move the locking rod 22 outward so that the locking rod 22 is separated from the cutting knife 3, and then adjust the angle of the cutting knife 3. After the adjustment is completed, move the locking rods 22 on both sides inward so that the locking rods 22 on both sides contact the cutting knife 3, and the cutting knife 3 is embedded in the locking groove 221, and then rotate the locking column 231 so that the locking column 231 contacts the locking rod 22, fix the position of the locking rod 22, and then complete the angle adjustment of the cutting knife 3. It should be pointed out that the position of the locking rod 22 is located on the outside of the lower fin, and does not affect each other during the process of lifting and cutting the fin.

[0026] Specifically, the cutting table 2 is provided with an angle scale, which matches the locking groove 221, making the adjustment more convenient and efficient.

[0027] This equipment can process fins at multiple angles, does not require handling equipment, is easy to adjust, has high processing efficiency, and has high equipment utilization rate.

[0028] As an improved specific implementation, a clamping mechanism 5 is provided on the lower side of the cutting table 2, and the clamping mechanism 5 includes:

[0029] A lifting slot 51 is vertically arranged on a side of the cutting blade 3 facing the propulsion mechanism 4;

[0030] A connecting groove 52 is provided at the bottom of the cutting table 2, and the position of the connecting groove 52 is offset from the fin below;

[0031] An adjusting rod 53, one end of which is movably connected to the lifting slot 51, and the other end of which passes through the connecting slot 52;

[0032] The clamping rod 54 has two ends connected to the adjusting rods 53 on both sides respectively. The clamping rod 54 is arranged at the lower side of the adjusting rod 53 , and the clamping rod 54 is rotatably connected to the adjusting rod 53 .

[0033] Through the above technical solution, when the cutting table 2 descends to cut the fin, the clamping rod 54 first contacts the fin, and then the cutting table 2 continues to descend. At this time, the adjusting rod 53 rises relatively in the lifting groove 51 and the connecting groove 52, and the clamping rod 54 always fits the fin, while the cutting knife 3 continues to descend to cut the fin; after the cutting is completed, during the rising process of the cutting table 2, the cutting table 2 drives the cutting knife 3 to rise. At this time, the adjusting rod 53 falls relatively in the lifting groove 51 and the connecting groove 52, and the clamping rod 54 always fits the fin until the adjusting rod 53 contacts the lower end of the lifting groove 51 and the connecting groove 52 and is driven to rise. At this time, the adjusting rod 53 rises with the clamping rod 54, so that the clamping rod 54 is separated from the fin. When the angle adjustment of the cutting knife 3 drives the adjusting rod 53 to move, the clamping rod 54 moves to match its movement without secondary adjustment, which is convenient to use.

[0034] It should be pointed out that, in the case of the clamping mechanism 5, when adjusting the angle of the cutting blade 3, the change in the angle of the cutting blade 3 drives the adjustment rod 53 to move, the angle of the adjustment rod 53 changes, the angle between the adjustment rod 53 and the lifting slot 51 is adjustable, and the adjustment rod 53 is movably connected to the connecting slot 52, and no manual adjustment is required, which is convenient to use. By clamping before cutting the fins, the yield rate of the fins is improved. In addition, the clamping mechanism 5 can change with the change in the angle of the cutting blade 3, without dead angles, and is convenient to use.

[0035] As an improved specific implementation, the clamping mechanism 5 further includes:

[0036] A pressing groove 55 is provided on the upper side of the adjusting rod 53;

[0037] A clamping seat 56 is arranged on the upper side of the adjusting rod 53, and a clamping spring 57 is arranged between the clamping seat 56 and the cutting table 2;

[0038] The movable rod 58 is rotatably connected to the pressing seat 56 and is located at the lower side of the pressing seat 56 . The movable rod 58 is slidably connected in the pressing groove 55 .

[0039] Through the above technical scheme, when the cutting table 2 descends to cut the fins, the clamping rod 54 first contacts the fins, and then the cutting table 2 continues to descend, the distance between the clamping seat 56 and the cutting table 2 is continuously shortened, and the clamping spring 57 is compressed; after cutting the fins, when the cutting table 2 rises, the cutting table 2 drives the cutting knife 3 to rise, at this time the adjusting rod 53 relatively descends in the lifting groove 51 and the connecting groove 52, the clamping spring 57 is continuously reset to compensate for the rising distance of the lifting table, the gravity of the clamping seat 56 and the elastic force of the clamping spring 57 act on the adjusting rod 53 through the movable rod 58, and then act on the clamping rod 54, so that the clamping rod 54 is always in contact with the fins, until the adjusting rod 53 contacts the lower ends of the lifting groove 51 and the connecting groove 52 and is driven to rise, at this time the adjusting rod 53 rises with the clamping rod 54, and the clamping rod 54 is separated from the fins.

[0040] The clamping seat 56 and the clamping spring 57 ensure that the clamping mechanism 5 operates stably during the process of the cutting table 2 being lifted and lowered to cut the fins, thereby improving the stability during the cutting process.

[0041] The clamping groove 55 is slidably connected to the movable rod 58, and the clamping seat 56 is rotatably connected to the movable rod 58 to cooperate so that the clamping seat 56 is in place when the rotating cutting knife 3 drives the adjusting rod 53 to move. There is no need to adjust multiple parts, and it is easy to use.

[0042] As an improved specific implementation, the movable rod 58 is connected to the clamping groove 55 via a precision guide rail and a precision slide groove 21 .

[0043] Through the above technical solution, the movable rod 58 is connected to the clamping groove 55 through the precision guide rail and the precision slide groove 21. When the cutting knife 3 adjusts the angle to drive the adjusting rod 53 to move, the resistance between the adjusting rod 53 and the movable rod 58 is small, and the adjustment is easy and convenient with high efficiency.

[0044] As an improved specific implementation, the side of the connecting groove 52 is arranged in an arc shape.

[0045] Through the above technical solution, the arc-shaped side of the connecting groove 52 can adjust the angle of the cutting knife 3 to drive the adjustment rod 53 to move more smoothly and with less wear.

[0046] As an improved specific implementation, a positioning rod 61 is provided on the upper side of the pressing seat 56 , a positioning hole 62 is provided on the cutting table 2 , and the positioning rod 61 is slidably connected in the positioning hole 62 .

[0047] Through the above technical solution, during the lifting and lowering movement of the clamping seat 56 relative to the cutting table 2, the positioning rod 61 always slides in the positioning hole 62, so that the position of the clamping seat 56 is stable, and a vertical downward force is applied to the lower adjustment rod 53 and the clamping rod 54 to clamp the fins below to avoid crooked fins.

[0048] Furthermore, when the cutting blade 3 is adjusted in angle, the position of the pressing seat 56 remains unchanged, and no manual fixation is required, which is convenient to use.

[0049] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
