[0003] For example, a Chinese patent (application number: 2018206769374) discloses a knife holder device for a flatbed machine, including an outer rotating shaft, a through hole is opened on the outer rotating shaft, a fixed tube is connected to the inner wall of the through hole, a movable shaft is connected to the inside of the fixed tube, a gear is sleeved on the movable shaft, a gear is engaged with the gear, a driving rod is fixedly connected to the gear, the movable shaft is connected to a fixed arm, the fixed arm is connected to a connector, and a knife head is connected to the end of the connector away from the fixed arm. The utility model has a movable shaft, a gear and a gear located inside the fixed tube, and a reasonable mechanical structure, so that the connector can rotate along the Y axis.

[0004] Although this solution can realize the rotation of the connecting head, it cannot meet the requirement of real-time adjustment of the cutting knife along the operation path during actual operation. There will still be a large deformation at the junction of straight lines and curves, resulting in large cutting errors and affecting the cutting quality. Utility Model Content

[0005] In order to solve the above problems, the embodiment of the utility model provides a single-drive actively rotating double-knife trolley device for adjusting the rotation angle of a cutting knife or a rolling knife during the cutting process.

[0010] A guide sleeve used in conjunction with the knife sleeve is arranged on one side of the mounting frame, and a guide column corresponding to the position of the lifting seat is arranged on the other side. A shaft holding structure used in conjunction with the guide column is arranged on the side wall of the lifting seat.

[0011] The shaft-holding structure includes guide bearings arranged on both sides of the guide column, and the guide bearings are connected to the lifting seat through a connecting shaft.

[0012] The connecting shaft is an eccentric shaft.

DETAILED DESCRIPTION

[0027] 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.

[0028] like Figure 1-8 As shown, the single-drive actively rotating double-knife trolley device of this embodiment includes a mounting frame 1, on which a rolling assembly 2 and a cutting assembly 3 are arranged. The rolling assembly 2 is used to form a cutting path after indentation processing on the paper, and the cutting assembly 3 cuts along the indentation. The upper part of the mounting frame 1 is provided with an angle adjustment device 4 for adjusting the rotation angle of the rolling assembly 2 and the cutting assembly 3. The angle adjustment device can drive the rolling knife and the cutting knife to rotate at an angle during operation, thereby reducing the deformation of the graphic and achieving a better cutting effect.

[0029] The angle adjustment device 4 includes a driving motor 5, which is a servo motor and has an output end that is vertically downward. The output end of the driving motor 5 is provided with a first driving wheel 6 and a second driving wheel 7, and the first driving wheel 6 is located below the second driving wheel 7. The upper part of the rolling component 2 and the cutting component 3 is provided with a driven wheel 8 that is respectively linked to the first driving wheel 6 and the second driving wheel 7. The first driving wheel 6 and the second driving wheel 7 are both linked to the driven wheel through belts. The use of belts can maintain a stable transmission relationship when the rolling component 2 and the cutting component 3 are adjusted for a small longitudinal spacing.

[0030] The rolling assembly 2 and the cutting assembly 3 both include a driving source 9, which adopts a voice coil motor. The output end of the driving source 9 is provided with a lifting seat 10 for driving the rolling assembly 2 or the cutting assembly 3 to perform longitudinal displacement. The lifting seat 10 is provided with a knife sleeve 11 for installing the rolling knife and the cutting knife. The upper part of the knife sleeve 11 is connected to the driven wheel 8. The rotation angle of the rolling knife and the cutting knife is adjusted as the driven wheel 8 rotates. A knife shaft is installed in the knife sleeve 11 in the cutting assembly 3. The cutting knife is installed at the lower end of the knife shaft, and an adjusting knob for adjusting the height of the knife shaft is provided at the upper end. The height of the cutting knife can be fine-tuned by using the adjusting knob.

[0031] A guide sleeve 12 for use with the tool sleeve 11 is provided on one side of the mounting frame 1, and a guide column 13 corresponding to the position of the lifting seat 10 is provided on the other side. A shaft holding structure for use with the guide column 13 is provided on the side wall of the lifting seat 10. Through the cooperation of the guide sleeve 12 and the guide column 13 with the shaft holding structure, longitudinal lifting and lowering guidance is performed at the front and rear ends of the lifting seat 10 respectively to ensure the stability of lifting. A guide screw is provided on the side wall of the tool shaft, and a guide groove corresponding to the position of the guide screw is provided on the side wall of the tool sleeve.

[0032] The shaft holding structure includes guide bearings 14 installed on both sides of the guide column 13. The guide bearings 14 are connected to the lifting seat 10 through a connecting shaft 15. The connecting shaft 15 is an eccentric shaft. The eccentric shaft can adjust the fit between the guide shaft 14 and the guide column 13 by rotation, so that the surface of the guide bearing 14 always fits the guide column 13, thereby improving the guiding effect.

[0033] A connecting back plate 16 is disposed on the outer side of the mounting frame 1, and a sliding bearing 17 is disposed on the connecting back plate 16 for sliding connection with the moving cross beam. The sliding bearing 17 is a deep groove ball bearing, which can not only play a guiding role but also reduce the friction during the installation and movement.

[0034] A lampshade 18 is provided at the lower part of the mounting frame 1, and a camera 19 and a lighting lamp 20 are installed in the lampshade 18. The bottom of the lampshade mounting frame can isolate external light during operation, reduce the lighting area, and enhance the illumination per unit area, making the captured image clearer.

[0035] Working principle / assembly process of this solution: First, rolling operation is carried out. The rolling knife moves along a pre-set path. The voice coil motor drives the rolling knife to fall and fit the material, leaving an indentation on the surface of the material. The pre-set path machine has both straight lines and curves. The XY axis servo motor of the flat machine controls the path. The servo motor controls the rotation direction of the roller along the path at all times. The rolling direction is always consistent with the direction of the path. Even sharp corners can be rolled out with precise effects. After the rolling operation is completed, the rolling knife rises, the cutting knife falls, and the cutting operation begins. The cutting process is the same as the rolling process, and the cutting path is the same as the rolling path. During the movement of the cutting knife, the servo motor will drive the cutting knife to rotate to avoid the problem of excessive cutting deformation at the connection between the curve or the straight line and the curve.
