Description

Technical Field

[0001] The utility model relates to the technical field of flatbed machines, in particular to a double-cutter head processing trolley pressure increasing device used for flatbed machines. Background Art

[0002] When the flatbed machine is in use, the computer automatically transmits the design and layout information to the flatbed machine controller, and the controller converts the information into a power signal (pulse train) that can drive the servo motor to control the X and Y axis of the flatbed machine to move the tool path base diameter, and controls the cutting knife to cut the pattern during the movement. Most of the existing flatbed machines use a creasing knife for pre-crimping during the cutting operation, and then use the cutting knife for cutting. For example, a Chinese patent (publication number: CN220007970U) discloses a digital cutting machine double-knife trolley based on a dual voice coil motor, including a seat, a first fixed seat and a second fixed seat are arranged on the seat, and the first fixed seat is fixed to the first fixed seat. A guide rod is arranged between the fixed seat and the second fixed seat, and the guide rod includes a first guide rod, a second guide rod and a third guide rod; a voice coil motor is arranged between the first fixed seat and the second fixed seat, and the voice coil motor is arranged vertically, and the voice coil motor includes a first output end and a second output end, and the first output end is located above the voice coil motor, and the second output end is located below the voice coil motor; a first knife handle is connected to the first output end, and cooperates with the first guide rod and the second guide rod, and the first knife handle moves up and down along the two guide rods; a second knife handle is connected to the second output end, and cooperates with the first guide rod and the third guide rod, and the second knife handle moves up and down along the two guide rods; a knife head is arranged on the first knife handle and the second knife handle. The above-mentioned digital cutting machine double-knife trolley has the advantage of assembling two knife heads at the same time.

[0003] However, the dual drive can only control the operating pressure through the motor during use. The flatbed machine trolley has low pressure during the cutting process, and it is difficult to adjust the pressure required by the knife, resulting in unstable cutting or rolling, or cutting of dotted lines or poor rolling effects.

[0006] As a further improvement of the above technical solution:

[0007] The creasing module and the cutting module both include a driving source arranged in a mounting frame, a lifting frame is arranged at an output end of the driving source, a linear bearing is arranged at one end of the lifting frame, and a guide seat is arranged at the other end.

[0008] The front end of the mounting frame is provided with a first guide column used in conjunction with the linear bearing, and the rear end is provided with a second guide column used in conjunction with the guide seat.

[0009] The guide seat comprises two guide bearings respectively located on both sides of the second guide column, and a positioning shaft connected with the lifting frame is arranged in the middle of each guide bearing.

[0010] One of the positioning shafts is an eccentric shaft, and a fastening screw used in conjunction with the eccentric shaft is provided on one side of the lifting frame.

[0013] A storage cavity is arranged at the lower part of the mounting frame, a lighting lampshade is arranged in the storage cavity, and an LED lamp and a camera are arranged in the lighting lampshade.

[0014] The beneficial effects of the embodiments of the utility model are as follows: 1. The double-head processing trolley increases the pressure device, including a mounting frame, in which an indentation module and a cutting module are arranged, and a pressure transmission device is arranged above the indentation module and the cutting module. The pressure transmission device can be used to alternately supplement the pressure of the indentation module and the cutting module, thereby ensuring that the pressure rate of rolling and cutting remains stable during the operation, and finally achieving the effect of improving the cutting accuracy.

[0015] 2.

[0024] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0025] like Figure 1-7 As shown, the double-head processing trolley increased pressure device of this embodiment includes a mounting frame 1, in which an indentation module 2 and a cutting module 3 are arranged, and a pressure transmission device 4 is arranged above the indentation module 2 and the cutting module 3. The pressure can be adjusted during the operation process through the pressure transmission device 4. Compared with the existing equipment, the module in the non-operating state can be used to apply pressure to the module in the operating state, thereby improving the pressure stability during rolling and cutting, and avoiding the problem of cutting dotted lines or poor rolling effect.

[0026] The creasing module 2 and the cutting module 3 both include a driving source 5 installed in the mounting frame 1. The driving source 5 adopts a voice coil motor. A lifting frame 6 is provided at the output end of the driving source 5. The lifting frame 6 drives the cutting knife or the rolling knife to adjust the height as the voice coil motor rises and falls. A linear bearing 7 is provided at one end of the lifting frame 6. A holder for mounting the cutting knife or the rolling knife is provided on the linear bearing 7. A guide seat 8 for maintaining the lifting stability of the lifting frame 6 is provided at the other end.

[0027] The front end of the mounting frame 1 is provided with a first guide column 9 used in conjunction with the linear bearing 7, and the rear end is provided with a second guide column 10 used in conjunction with the guide seat 8. The function of the first guide column 9 and the second guide column 10 is to cooperate with the linear bearing 7 and the guide seat 8 to increase the lifting and lowering stability of the indentation module 2 and the cutting module 3.

[0028] The guide seat 8 includes two guide bearings 11 respectively located on both sides of the second guide column 10. A positioning shaft 12 connected to the lifting frame 6 is provided in the middle of each guide bearing 11. The guide bearing 11 plays a guiding role when the lifting frame 6 is raised or lowered, and can reduce the friction with the second guide column 10.

[0029] One of the positioning shafts 12 is an eccentric shaft 13 , and a fastening screw 14 used in conjunction with the eccentric shaft 13 is provided on one side of the lifting frame 6 . The design of the eccentric shaft can adjust the distance between the two guide bearings 11 so that it always fits with the second guide column 10 .

[0030] The pressure transmission device 4 includes a transmission rod 15, a rotating shaft 16 connected to the lifting frame 6 is provided in the middle of the transmission rod 15, and rotating wheels 17 are provided at both ends of the transmission rod 15 to fit the upper surfaces of the two lifting frames 6. When cutting is not required, the voice coil motor located in the cutting module 3 drives the corresponding lifting frame 6 to move upward. At this time, the transmission rod 15 rotates toward the indentation module 2 and applies downward pressure to the lifting frame 6 in the indentation module 2 to increase the pressure stability during rolling. Conversely, pressure is applied to the cutting module 3 to increase the pressure stability during cutting operation.

[0031] The upper surface of the lifting frame 6 is provided with a wear-resistant plug 18 corresponding to the position of the rotating wheel 17. The wear-resistant plug 18 can improve the wear resistance of the joint between the lifting frame 6 and the rotating wheel 17, reduce the wear on the lifting frame 6, and increase the service life.

[0032] A storage cavity 19 is provided at the lower part of the mounting frame 1, and a lighting lampshade 20 is provided in the storage cavity 19. The lighting lampshade 20 is provided with an LED lamp 21 and a camera 22. The lighting lampshade 20 can isolate external light and reduce the irradiation area of ​​the LED lamp 21, thereby achieving the effect of improving the illumination, facilitating the positioning of the trolley, and improving the cutting accuracy.

[0033] The working principle / assembly process of this scheme: first, the creasing operation is carried out, and the voice coil motor in the creasing module 2 is energized to drive the lifting frame 6 in the creasing module 2 to move downward, so that the height of the creasing knife is lowered and then the creasing operation is carried out. When the operating pressure is insufficient, the reverse current is connected to the voice coil motor in the cutting module 2 to drive the lifting frame 6 in the cutting module 2 to move upward. At this time, the transmission rod 15 will rotate toward the creasing module 2 under the action of the height difference, exerting downward pressure on it to ensure the stability of the creasing operation. On the contrary, when cutting is required, the transmission rod 15 is used to apply pressure to the cutting module 2 to enhance the cutting stability.
