Specific implementation

[0020] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments only are a part of the embodiments of the utility model, and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without making creative labor belong to the range of protection of the utility model.

[0021] Embodiment 1:

[0022] Please refer to Figures 1-4 From, including operation platform 1 and baffle 2, the bottom of operation platform 1 is installed with crossbeam 11, and crossbeam 11 is installed with moving assembly 3, and moving assembly 3 includes connecting plate 34, and the top of connecting plate 34 is installed with clamping assembly 4, and clamping assembly 4 includes fixed plate 41, and fixed plate 41 is fixedly installed on connecting plate 34, and fixed plate 41 is fixedly installed with slide rod one 43, and the both ends of slide rod one 43 are slidably installed with moving frame 44, and moving frame 44 is screw-connected with two-way screw rod 46, and two-way screw rod 46 is rotatably installed on fixed plate 41, and two-way screw rod 46 is connected with the output end of motor one 42, and the top of moving frame 44 is fixedly installed with support plate 45, and support plate 45 is installed with bearing 5, and the rotating shaft in the middle of bearing 5 is connected with clamping plate 6;

[0023] The rotating shaft in the middle of bearing 5 is connected with the output end of motor two 7, and the annular array of clamping plate 6 is provided with plug rod 61, and plug hole 62 is arranged between two adjacent plug rods 61, and the plug rod 61 on the top of two moving frames 44 and plug hole 62 correspond to each other and are adapted to each other.

[0024] The cutting piece 8 is clamped between the clamping plate 6 on the top of two moving frames 44, and the annular array of cutting piece 8 is provided with mounting hole 81, and mounting hole 81 corresponds to plug rod 61 and is adapted to plug rod 61, and the number of mounting hole 81 is same with the sum of the number of plug rod 61 and plug hole 62 on a single clamping plate 6.

[0025] Specifically, the starting motor 42 drives the bidirectional threaded rod 46 to rotate. Since the moving frame 44 is screw-connected with the bidirectional threaded rod 46, and the slide rod 43 limits the movement direction of the moving frame 44, the two moving frames 44 can move relatively or oppositely on the slide rod 43 along the rotation direction of the bidirectional threaded rod 46.

[0026] When the two moving frames 44 move relatively, the clamping plates 6 on the top of the two moving frames 44 also move close to each other. The insertion rod 61 on the clamping plate 6 is inserted into the mounting hole 81 on the cutting sheet 8 and the corresponding insertion hole 62 on the other clamping plate 6, thereby clamping the cutting sheet 8. Since the insertion rod 61, the insertion hole 62 and the mounting hole 81 are annular arrays and correspondingly matched with each other, the cutting sheet 8 can be uniformly and stably clamped between the two clamping plates 6.

[0027] Through the cooperation of the insertion rod 61, the insertion hole 62 and the mounting hole 81, the cutting sheet 8 can be accurately positioned and kept stable during rotation. Moreover, the cutting sheet 8 is supported by the bearing 5, which provides a low-friction rotating environment and reduces shaking and deviation during rotation. By using the support of the bearing 5 and the support plate 45, the deformation of the rotating shaft can be avoided, so that the cutting sheet 8 can always be kept in the accurate cutting plane, effectively improving the cutting accuracy.

Because connecting arm two 342 is screw connected with unidirectional threaded rod 33, connecting arm one 341 is slidingly connected with slide rod two 32, and slide rod two 32 plays a guiding role, when unidirectional threaded rod 33 rotates, it will make connecting plate 34 move along the direction of slide rod two 32. Because the top of connecting plate 34 is installed with clamping assembly 4 and cutting blade 8, cutting blade 8 will move to the appropriate cutting position along with connecting plate 34;

[0033] When cutting blade 8 rotates and moves to the position of the material to be cut, the material can be cut. During the cutting process, the position of cutting blade 8 can be continuously adjusted by motor three 31 as needed to complete cutting of different lengths;

[0034] The design of moving assembly 3 makes cutting blade 8 flexible on cross beam 11. Whether it is long-distance cutting of large materials or local fine cutting of small materials, it can be easily coped with. The cutting position can be quickly adjusted according to the actual cutting demand, adapt to different cutting scenes, improve the versatility and applicability of the equipment.

[0035] Working principle: start motor one 42, which drives bidirectional threaded rod 46 to rotate, makes two moving frames 44 move relatively on slide rod one 43, the clamping plate 6 on the top of the moving frame 44 approaches, the insertion rod 61 on the clamping plate 6 is inserted into the mounting hole 81 on the cutting blade 8 and the corresponding insertion hole 62 on the other clamping plate 6, realizing stable clamping of the cutting blade 8;
