Description
Technical Field
[0001] The utility model relates to the technical field of material conveying, in particular to a feeding mechanism of a numerically controlled cutting machine. Background Art
[0002] CNC cutting machines are highly efficient woodworking equipment widely used in the production of cabinets, wardrobes, and panel furniture. They can automatically cut, punch, groove, and change tools. When used with professional furniture design and ordering software, CNC cutting machines enable intelligent, customized production, improving production efficiency and precision.
[0003] However, on many production lines, the loading process of CNC cutting machines still relies on traditional manual methods. While this loading method can solve the problem of sheet material loading to a certain extent, its inherent limitations are becoming increasingly prominent. Manual loading is not only inefficient and difficult to match the efficient processing capabilities of the cutting machine, but also poses significant safety risks. Workers need to frequently handle and carry heavy sheets, which can easily cause injuries and accidents due to improper operation. The lack of precision makes it difficult to ensure the precise position and angle of the sheets, affecting product quality. The labor cost is high, requiring the employment of a large number of workers and the wage level is constantly increasing. Therefore, a CNC cutting machine loading mechanism is provided to solve the above problems. Utility Model Content

[0013] Further configuration: Universal wheels are provided on the sides of the first support frame and the second support frame facing the ground.
[0014] In summary, the present invention has the following beneficial effects:
[0015] 1. When the plate needs to be loaded, the plate is placed on the placement plate, and the motor fixedly connected to the support rod rotates. The rotation of the motor drives the worm fixedly connected to it to rotate on the bracket. The rotation of the worm drives the worm gear adapted to it to rotate. The rotation of the worm gear drives the rotating shaft fixedly connected to it to rotate on the first support frame and the second support frame. The rotation of the rotating shaft drives the connecting member provided thereon to move. The movement of the connecting member drives the placement plate fixedly connected to it to slide in the sliding groove of the first support frame and the second support frame. The movement of the placement plate drives the plate on the placement plate to move up and down. When the placement plate reaches the required height, the pusher on one side of the first support frame and the second support frame moves, pushing the plate on the placement plate, thereby pushing the plate out of the placement plate, realizing the loading of the plate, reducing the burden on the staff and improving work efficiency. The worm and worm gear have a self-locking function, which can play a certain role in limiting the placement plate.
[0016] The movable plate is pushed forward by the action of the cylinder and the output shaft of the cylinder drives the first slider fixedly connected to it to slide in the first slide groove of the support plate. The movement of the first slider drives the first connecting plate rotatably connected to it to move. The movement of the first connecting plate drives the movable plate rotatably connected to it to move. Since the first connecting plate and the second connecting plate are cross-hinged with each other and one end of the second connecting plate is rotatably connected to the support plate, the movement of the first connecting plate drives the second connecting plate to rotate on the support plate, and the movement of the second connecting plate drives the second slider rotatably connected to it to slide in the second slide groove of the movable plate. Through the scissor-type working principle, the movable plate is pushed, and the movement of the movable plate pushes the plate on the placement plate into the discharge plate, thereby pushing the plate on the placement plate out and loading.
[0017] 3. The first fixed block, the second fixed block, the third fixed block and the fourth fixed block move to the limit blocks in the sliding grooves on the first support frame and the second support frame, which are used to limit the first fixed block, the second fixed block, the third fixed block and the fourth fixed block, thereby limiting the rising height of the placement plate.

[0033] Working principle:
[0034] When it is necessary to load the plate, the plate is placed on the placement plate 2. At this time, the staff controls the motor 9 fixedly connected to the support rod 6 to rotate. The rotation of the motor 9 drives the worm 10 fixedly connected to it to rotate on the bracket 11. The rotation of the worm 10 drives the worm wheel 12 adapted to it to rotate. The rotation of the worm wheel 12 drives the rotating shaft 13 fixedly connected to it to rotate. The rotation of the rotating shaft 13 drives the first rope wheel 15 and the second rope wheel 14 fixedly connected to it to rotate. The rotation of the first rope wheel 15 drives the first traction rope 18 and the second traction rope 19 wound around it to move. The second rope wheel 18 drives the first traction rope 19 and the second traction rope 19 wound around it to move.

[0035] When the first fixed block 33, the second fixed block 34, the third fixed block 35 and the fourth fixed block 36 touch the limit block 43 in the sliding groove 42, the motor 9 stops rotating. At this time, the output shaft of the cylinder 7 contracts and drives the first slider 27 fixedly connected thereto to move in the first sliding groove 26 on the support plate 5. The movement of the first slider 27 drives the first connecting plate 28 rotatably connected thereto to move. The movement of the first connecting plate 28 drives the movable plate 32 rotatably connected thereto to move. Since the first connecting plate 28 and the second connecting plate 29 are cross-hinged with each other, the first connecting plate 28 and the second connecting plate 29 are mutually hinged. A rotating pin is provided at the cross hinge, and the left end of the second connecting plate 28 is rotatably connected to the support plate 5. Therefore, the movement of the first connecting plate 28 drives the second connecting plate 29 to rotate on the support plate 5.
