Description

[Technical field]

[0001] The utility model relates to the technical field of plate cutting mechanisms, in particular to a dual-function cutting mechanism. [Background technology]

[0002] Shearing machines are widely used in cutting plates. They are very convenient to use and efficient. At present, if you want to get plates of appropriate length and width, you must first cut them through a shearing machine, and then transport the cut plates to a slitting machine for slitting to get the corresponding plates.

[0003] A multifunctional shearing machine disclosed in patent publication number CN208289090U belongs to the field of plate shearing. A multifunctional shearing machine includes a shearing machine body, which also includes a transverse shearing device transversely arranged on the body and a longitudinal shearing device arranged upstream of the transverse shearing device. The working planes of the transverse shearing device and the longitudinal shearing device are on the same plane as the shearing machine operating table. A positioning device is movably arranged on the shearing machine operating table. The positioning device includes two slide rails that are transversely arranged and flush with the operating table. Scale lines are provided on the two slide rails. Two positioning plates are longitudinally arranged between the two slide rails. The two ends of the positioning plate are movably arranged on the two slide rails. The utility model can perform transverse shearing, longitudinal shearing, or transverse and longitudinal double shearing on the plate; it reduces labor intensity and improves production efficiency.

[0004] The utility model mainly achieves the cutting of the plate by utilizing the overlap of the second tool. Although the plate can be cut in this way, the function of the cutting mechanism is relatively single, and it can only cut the plates in the same direction. When the plates need to be cut in different directions, personnel are required to take out the plates that have been cut in one direction and change the position of the plates again to achieve the cutting of the plates, which will bring unnecessary inventions to personnel and reduce the cutting efficiency of the plates. [Contents of the utility model]

[0005] The purpose of the utility model is to solve the problems in the prior art and to propose a dual-function cutting mechanism that can cut plates in different directions, thereby increasing the cutting efficiency of plates through single-direction and dual-function cutting in different directions.

[0006] To achieve the above purpose, the utility model proposes a dual-function cutting mechanism, including a base with a groove on the top surface and a bracket mounted on the base.

[0007] A movable column is slidably connected to the bracket, and a support block is relatively slidably connected to the movable column. A driving member with one end connected to the support block is provided on the movable column, and the driving member can drive the support block to move relatively. A cutting knife is rotatably connected to the support block, and a rotating member with one end connected to the cutting knife is provided on the support block, and the rotating member can drive the cutting knife to rotate.

[0008] Preferably, the driving member includes a main bidirectional lead screw rotatably connected to the moving column and a main motor fixedly connected to the moving column, the output shaft of the main motor is fixedly connected to the main bidirectional lead screw, and the main bidirectional lead screw is threadedly connected to the support block.

[0009] Preferably, a main cylinder is fixedly connected to the bracket, and one end of the main cylinder is fixedly connected to the moving column.

[0010] Preferably, the rotating member includes a main spur gear rotatably connected to the support block and an arc rack fixedly connected to the cutting knife, the arc rack meshes with the main spur gear, and the support block is fixedly connected to a secondary motor whose output shaft is fixedly connected to the main spur gear.

[0011] Preferably, a plurality of main balls are rotatably connected to the support block, and the main balls are in contact with the movable column.

[0012] Preferably, a plurality of secondary balls are rotatably connected to the arc rack, and the secondary balls are in contact with the support block.

[0013] Beneficial effects of the utility model: Compared with the prior art, the rotating part of the utility model is connected to the cutting knife, so that the cutting knife rotates, and in this way the cutting knife can be adjusted to different positions, and this method is used to achieve single-direction and multi-directional dual-function cutting, thereby increasing the cutting effect of the plate.

[0014] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings.

[Specific implementation method]

[0018] like Figures 1 to 2 A dual-function cutting mechanism comprises a base 1 with a groove 2 on the top surface and a bracket 3 mounted on the base 1.

[0019] In actual operation, since the movable column 4 is slidably connected to the bracket 3 and the driving member 6 is fixedly connected to the movable column 4, the driving member 6 is started, and the supporting block 5 connected to it and relatively slidably connected to the movable column 4 can be driven to move through the driving member 6, and the supporting block 5 drives the cutting knife 7 rotatably connected to the supporting block 5 to cut the plate. When the position of the cutting knife 7 needs to be adjusted, the rotating member 8 fixedly connected to the supporting block 5 is started, and the cutting knife 7 connected to it is driven to rotate through the rotating member 8, thereby further improving the position adjustment degree of the cutting knife 7.

[0020] When the support block 5 needs to move relatively, since the driving member 6 includes a main bidirectional lead screw 9 rotatably connected to the moving column 4 and a main motor 10 fixedly connected to the moving column 4, the output shaft of the main motor 10 is fixedly connected to the main bidirectional lead screw 9, and the main bidirectional lead screw 9 is threadedly connected to the support block 5, the main motor 10 is started, and the main bidirectional lead screw 9 can be driven to rotate by the main motor 10, and the main bidirectional lead screw 9 can drive the support block 5 to move relatively during the rotation, thereby further improving the movement effect of the support block 5.

[0021] When the moving column 4 needs to move, the main cylinder 11 fixedly connected to the bracket 3 is started, and the output shaft of the main cylinder 11 is fixedly connected to the moving column 4, so that the main cylinder 11 can drive the moving column 4 to move, further improving the movement effect of the moving column 4.

[0022] When the cutting knife 7 needs to rotate, since the rotating member 8 includes a main spur gear 12 rotatably connected to the support block 5 and an arc rack 13 fixedly connected to the cutting knife 7, the arc rack 13 is meshed with the main spur gear 12, and a secondary motor 14 with an output shaft fixedly connected to the support block 5 and fixedly connected to the main spur gear 12, the secondary motor 14 fixedly connected to the support block 5 is started, and the output shaft of the secondary motor 14 and the main spur gear 12 are rotated, and the main spur gear 12 drives the arc rack 13 to rotate during the rotation process, and the arc rack 13 is linked to the cutting knife 7 to rotate, so as to further improve the adjustment effect of the position of the cutting knife 7.

[0023] When the support block 5 moves, the main ball 15 rotatably connected to the support block 5 is in contact with the moving column 4 , thereby reducing the friction between the support block 5 and the moving column 4 .

[0024] When the arc rack 13 rotates, since a plurality of secondary balls 16 are rotatably connected to the arc rack 13 , the secondary balls 16 can reduce the friction between the arc rack 13 and the support block 5 .

After the cutting knife 7 is adjusted in angle, the driving member 6 drives the supporting block 5 to move relatively, thereby achieving the cutting of the plate.
