Example one
In the embodiment, in order to realize continuous cutting of a coating which is not coated on the surface of a plate on a plate gap in an automatic and integrated manner, the pushing mechanism is arranged right above a plate conveying plane, the sliding distance of the cutting mechanism is controlled by the pushing mechanism, a cutting knife of the cutting mechanism is arranged on the plate conveying plane, meanwhile, the cutting direction of the cutting knife is set to be vertical to the plate conveying direction, then, the pushing angle of the pushing mechanism is controlled, and the pushing angle, the plate conveying speed and the pushing speed of the pushing mechanism form a functional relationship; the pushing speed and the pushing angle of the pushing mechanism are directly linked by establishing a functional relation, so that the speed in the conveying direction of the plate conveying plane is consistent with the pushing speed in the same direction of the conveying direction of the plate conveying plane, and the relative rest of the two is realized; when the cutting machine is used for cutting, the speeds in the same direction are consistent, the cutting knife can synchronously cut along the conveying direction of the plate conveying plane, and the phenomenon of mutual blocking cannot occur, so that the coating film in the plate gap can be cut or trimmed, and the coating film which is not coated on the surface of the plate in the plate gap can be continuously cut integrally; for example:
the embodiment places the plate with the film on the plate conveying plane for conveying, when the cutting knife cuts the film between the plate gaps, the speed of the conveying direction of the plate conveying plane is consistent with the pushing speed (namely the cutting speed of the cutting knife) of the same direction of the conveying direction of the plate conveying plane, and the two are relatively static, so that the cutting knife can be always attached to the plate, then the cutting knife on the cutting mechanism is pushed by the pushing mechanism to cut the film which is not applied on the surface of the plate, on the basis of continuous conveying of the plate conveying plane, the film which is not applied on the surface of the plate on the plate gaps can be integrally cut, the plate conveying plane does not need to stop running, the film on the surface of the plate can be continuously cut, the cutting efficiency of the film is greatly improved, the cost for using various devices is saved, and the production cost is reduced.
In addition, the pushing angle of the pushing mechanism refers to an included angle formed between the pushing direction of the pushing mechanism and the side edge of the gap of the plate; specifically, because the speed is a vector, the defect that the existing plate needs to be stopped when cutting and laminating the plate is avoided and the cutting efficiency is improved by changing the pushing direction of the pushing mechanism and controlling the pushing speed of the pushing mechanism and the conveying speed of the plate conveying plane; the ratio of the conveying speed to the pushing speed is set to be equal to the sine value of the pushing angle, the pushing angle is set to be an acute angle, and by controlling the relationship of the conveying speed, the pushing speed and the pushing speed, the film covering on the gap of the plate can be effectively cut by using the cutting knife without errors; for example, the pushing angle is set to 30 degrees, namely, the included angle formed by the pushing direction of the pushing mechanism and the side edge of the plate gap is set to 30 degrees, then the pushing speed value of the pushing mechanism and the conveying speed value of the plate conveying plane are set through a trigonometric function relation, and due to the existence of the pushing angle, the pushing speed of one side in the same direction with the plate conveying plane is consistent with the conveying speed of the plate conveying plane, and in the cutting process, the pushing angle and the conveying speed value are relatively static, so that the cutting knife can accurately cut or trim the coating film of the plate gap which is continuously conveyed.
It should be noted that, the pushing mechanism in this example is composed of a transmission belt, a guide rod, a servo motor and other components; the cutting mechanism is fixed on the transmission belt, and the speed control of the transmission belt can be realized by controlling the rotating speed of the servo motor; specifically, the arrangement direction of the guide support rod is controlled, namely the guide support rod is arranged above the plate conveying plane, and an included angle formed by the axis of the guide support rod and the side edge of the plate gap is consistent with the above-mentioned pushing angle, so that automatic cutting of the plate coating and continuous cutting of the plate coating can be realized; in addition, in order to improve the transmission belt and stably drive the cutting mechanism to push and cut, one side of the guide supporting rod is provided with a sliding rail, and the cutting mechanism is connected with the sliding rail in a sliding mode.
It is worth noting that in order to solve the problem of how to automatically reset the cutting mechanism, the cutting mechanism comprises a cutting head, a first connecting piece, a second connecting piece, a cylinder and the like; wherein the cutting knife is fixed on the cutting head, the cutting head is fixed on the first connecting piece, the second connecting piece is connected with the first connecting piece in a sliding way, and the second connecting piece is fixed on a transmission belt of the pushing mechanism; the sliding gear is rotated by the servo motor to drive the transmission belt to carry out transmission, the second connecting piece is driven by the transmission belt to change the position of the second connecting piece, meanwhile, the first connecting piece which is connected with the second connecting piece in a sliding way is driven, and finally, the cutting knife on the cutting head is driven by the first connecting piece to carry out cutting; in addition, in order to achieve automatic reset after the film covering of the plate gap is cut once and not affect the transportation of the plate transportation plane, the air cylinder is adopted to control the longitudinal sliding distance of the first connecting piece, the sliding direction of the first connecting piece is set to be perpendicular to the plate transportation plane, so that after the film covering is cut, the first connecting piece is pulled up through the air cylinder, the cutting knife on the cutting head is further pulled up, the cutting knife is far away from the plate transportation plane, then the cutting mechanism is returned to the original cutting starting position through the reverse rotation of the servo motor, the first connecting piece is lowered through the air cylinder, the transmission belt is rotated, and the cutting is performed again, and therefore the continuous cutting of the film covering of the plate gap is achieved without hindrance, and the cutting efficiency is further improved.
In practical application, in order to enhance the practicability of the device, the device in this example further comprises a transportation body, namely, the plate transportation plane is located on the transportation body, specifically, the transportation body comprises at least two portal frames and a rotating roller, the two portal frames are aligned with each other to realize parallel, then the rotating roller is uniformly arranged on a cross beam of the portal frames, and two ends of the rotating roller are respectively connected with two cross beams of the portal frames in a rotating manner, so that the rotating roller is arranged on the cross beam to rotate, and the axes of all the rotating rollers are located on the same horizontal plane, so that the plate transportation plane is flat, the plate transportation plane can stably transport plates, and the cutting knife can conveniently cut the plates.
Example two
