Description

I. Technical Field

[0001] This invention relates to the field of printing equipment technology, specifically to an integrated rotatable composite cutting and printing device. II. Background Technology

[0002] Existing printers with cutting functions typically only have a single horizontal cutting mechanism, which can only cut paper horizontally to a fixed length, resulting in a limited cutting method. When it is necessary to process stepped structures on the printing medium (such as stepped labels, multi-sized ID cards, etc.), manual secondary alignment and cutting are often required, or multiple cutting machines are used for step-by-step processing. This is not only inefficient, but also results in large errors in manual alignment, making it difficult to guarantee cutting accuracy and failing to meet the needs of high-precision mass production.

[0003] In addition, some multi-directional cutting equipment uses multiple sets of fixed-arranged blade holders, which are large in size, complex in structure, and high in cost. Furthermore, the cutting direction adjustment is not flexible and cannot adapt to the flexible switching of various step sizes, thus limiting its applicability. III. Summary of the Invention

[0004] The purpose of this invention This invention addresses the shortcomings of existing technologies by providing a rotatable composite cutting and printing device that solves the problems of existing cutting printers being unable to efficiently and accurately process similar stepped structures and the inconvenience of adjusting the cutting direction.

[0005] Technical solution of the present invention An integrated rotatable composite cutting and printing device includes a frame, on which a paper feeding mechanism 2, a printing unit 3 and a first cutting unit are arranged sequentially along the paper feeding path. The cutting direction of the first cutting unit 4 is perpendicular to the paper feeding direction and is used to cut the paper laterally. The printer also includes a second composite cutting unit, an image alignment sensor and a control motherboard.

[0006] The second composite cutting unit 5 is located downstream of the first cutting unit and includes a sliding frame, a rotatable knife holder, a cutting drive 53, and a rotation drive 54. The sliding frame 51 is slidably disposed on the frame 1, and the sliding direction is perpendicular to the paper feeding direction. The rotatable knife holder 52 is rotatably mounted on the sliding frame 51, and the cutting drive 53 is fixed on the rotatable knife holder 52 and rotates synchronously with it. The rotation drive 54 is used to drive the rotatable knife holder 52 to rotate around an axis perpendicular to the paper plane to switch the cutting direction.

[0007] An image alignment sensor is located above the paper path between the printing unit 3 and the second composite cutting unit 5, and is used to collect alignment marks on the paper surface and output position signals.

[0008] The control motherboard is electrically connected to the paper feeding mechanism, printing unit 3, first cutting unit 4, second composite cutting unit 5 and image alignment sensor 15 respectively; the control motherboard is configured to receive the position signal of the image alignment sensor 15, control the moving position of the sliding frame, the rotation angle of the rotatable blade holder and the cutting sequence, and cooperate with the first cutting unit 4 to cut the paper to form a multi-level stepped structure.

[0009] The rotatable blade holder 52 has at least two working angles: when rotated to the first working angle, the cutting direction is parallel to the paper feeding direction; when rotated to the second working angle, the cutting direction is perpendicular to the paper feeding direction.

[0010] A linear drive module 6 is provided on the frame. The linear drive module 6 is electrically connected to the control motherboard 10 and is used to drive the sliding frame to move back and forth (left and right) along the sliding direction.

[0011] The image alignment sensor 15 is a CCD image sensor, and its acquisition end is set directly opposite the upper surface of the paper in the paper feeding path.

[0012] The control motherboard 10 has multiple step size parameters and cutting paths pre-stored. The control motherboard 10 calibrates the cutting coordinates according to the position signal of the alignment mark and calls the corresponding parameters to control the first cutting unit 4 and the second composite cutting unit 5 to perform the cutting action in coordination.

[0013] The frame is also equipped with an operation panel, which is electrically connected to the control motherboard and is used to input control commands for cutting size and working mode.

[0014] A waste collection box is provided on the frame below the first cutting unit 4 and the second composite cutting unit 5 to collect the scrap materials generated during cutting.

[0015] A direction marking protrusion is fixedly provided on the side of the rotatable tool holder. The direction marking protrusion rotates synchronously with the rotatable tool holder and is used to mark the rotation angle position of the tool holder.

[0016] The beneficial effects of this invention are: 1. Integrated design: Printing, horizontal cutting, and composite multi-directional cutting are integrated into the same machine. The paper can be fed in one pass to complete printing and stepped structure cutting. There is no need for manual secondary transfer and alignment, which greatly improves processing efficiency and reduces the space occupied by the equipment.

[0017] 2. Rotatable blade holder for composite cutting: By switching the cutting direction through the rotatable blade holder and cooperating with the lateral movement of the sliding frame, only one set of cutting mechanism can realize multi-directional cutting in the horizontal and vertical directions. The structure is simplified, the cutting direction can be flexibly switched, and it can be adapted to the processing of stepped structures of different specifications.

[0018] 3. Precise image alignment control: The image alignment sensor collects the alignment marks on the paper, calibrates the cutting coordinates in real time, eliminates cutting offset caused by paper feeding errors, greatly improves the cutting accuracy of stepped structures, and ensures the consistency of batch processing.

[0019] 4. High degree of automation: The control motherboard has multiple sets of step parameters pre-stored, and the cutting mode can be quickly switched through the operation panel. The equipment automatically completes the entire process of alignment, paper feeding, and multi-step cutting. It is easy to operate and suitable for batch production needs of home and printing shops.

IV. Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 5 As shown in the figure, the integrated rotatable composite cutting and printing device described in this embodiment includes a frame 1. A paper feeding mechanism, a printing unit, an image alignment sensor, a first cutting unit, and a second composite cutting unit 5 are arranged sequentially on the frame 1 along the paper feeding path. A control motherboard is arranged inside the frame 1, and an operation panel is arranged on the outside of the frame.

[0023] The paper feeding mechanism 2 adopts a roller-type paper feeding structure to uniformly feed the paper to be printed into the printing station. The paper feeding speed is controlled by the main control board and matched with the printing and cutting cycle. The printing unit uses an inkjet or laser printing module to print the preset pattern and alignment mark on the paper surface. In this embodiment, the alignment mark and pattern are printed simultaneously as a positioning reference for subsequent cutting.

[0024] The first cutting unit 4 is a transverse cutting mechanism. The cutting direction is perpendicular to the paper feed direction. It is used to complete the transverse cutting of the paper to a fixed length, forming the transverse edge of the stepped structure. The first cutting unit can adopt a flat-pressure cutter or a roller cutter structure, and the cutting triggering timing is controlled by the control motherboard.

[0025] The second composite cutting unit 5 is located downstream of the first cutting unit 4 and is the core component for realizing multi-directional cutting and processing of stepped structures. For example... Figure 2 As shown, the second composite cutting unit 5 includes a sliding frame, a rotatable blade holder, a cutting drive component 53, and a rotation drive component. The sliding frame is slidably mounted on the frame via a transverse guide rail 11, with the sliding direction perpendicular to the paper feed direction. A linear drive module 6 is mounted on the frame. The linear drive module 6 is a lead screw motor module, electrically connected to the control main board 10, used to drive the sliding frame to reciprocate (left and right) along the transverse guide rail, adjusting the transverse position of the cut.

[0026] The rotatable blade holder is rotatably mounted in the middle of the sliding frame via a rotating shaft, with the axis of rotation perpendicular to the plane of the paper. A cutting drive unit is fixedly mounted on the rotatable blade holder and rotates synchronously with it to perform the cutting action; the cutting drive unit 53 can be a small electromagnetically driven or motor-driven cutting blade structure. A rotary drive unit is fixed on the sliding frame, and its output end is connected to the rotating shaft of the rotatable blade holder to drive the rotatable blade holder to rotate 90°, switching the cutting direction.

[0027] In this embodiment, the rotatable blade holder has at least two working angles: when rotated to the first working angle, the cutting direction is parallel to the paper feeding direction and is used to cut the longitudinal side of the stepped structure; when rotated to the second working angle, the cutting direction is perpendicular to the paper feeding direction and is used to supplement the cutting of the transverse stepped edge of the stepped structure.

[0028] like Figure 3 As shown, a direction indicator protrusion is fixedly installed on the side of the rotatable tool holder, which rotates synchronously with the rotatable tool holder; a position detection switch can be installed at the corresponding position on the frame, which identifies the position of the direction indicator protrusion and calibrates the origin of the rotation angle of the tool holder to ensure the accuracy of angle switching.

[0029] The image alignment sensor is a CCD image sensor, installed above the paper path between the printing unit 3 and the second composite cutting unit 5, with the acquisition end facing the upper surface of the paper. When the printed paper passes by, the image alignment sensor 15 acquires the pre-printed cutting marks (such as crosshairs or L-shaped marks) on the paper surface and transmits the position signal to the control main board; the control main board calculates the paper feed offset based on the mark position, calibrates the subsequent cutting coordinates, and eliminates paper feed errors.

[0030] The control motherboard 10 is the control core of the equipment, and is connected to the paper feeding mechanism (module), printing unit, first cutting unit, linear drive module, rotary drive component, cutting drive component, image alignment sensor, and operation panel of the second composite cutting unit 5. The control motherboard 10 has multiple pre-stored step size parameters and corresponding cutting path programs. After the user selects the corresponding cutting mode and size through the operation panel, the control motherboard automatically calls the corresponding parameters and coordinates the actions of each component.

[0031] Below the first cutting unit 4 and the second composite cutting unit on the frame 1, there is a waste collection box to collect the scraps generated during the cutting process for easy centralized cleaning. In addition, there is a self-cleaning module that detects when a certain level of waste is reached and automatically cleans itself, resulting in a high degree of automation.

[0032] The specific working process of this invention is as follows: The user selects the (step) cutting mode and target size through the operation panel, and controls the main board 10 to call the corresponding cutting parameter program; The paper feeding mechanism 2 feeds the paper into the printing unit 3, and the printing unit 3 prints the target pattern and alignment mark 14 on the paper surface; The printed paper continues to feed forward. When it passes under the image alignment sensor 15, the sensor collects the alignment mark 14 and feeds back the position signal to the control motherboard 10. The control motherboard 10 calculates the offset between the actual position and the preset position and calibrates the cutting coordinates. The paper continues to be fed to the first cutting unit 4 station. The control motherboard 10 controls the first cutting unit 4 to perform transverse cutting according to the calibrated coordinates, and completes the cutting of the paper to a fixed length and the outermost transverse edge of the step. The paper continues to be fed to the second composite cutting unit 5 station. The control motherboard 10 controls the linear drive module 6 to move the sliding frame 51 to the target horizontal position. At the same time, it controls the rotary drive component 54 to drive the rotatable knife holder 52 to rotate to the corresponding angle. In conjunction with the paper feeding action, the longitudinal side of the stepped structure and the horizontal step edges of each level are cut out in sequence. The finished paper output device after cutting places the scraps into the waste collection box 16 below. Other examples correspond to items 8, 10, 11, and 12 of the instruction manual, respectively, as per 202610812486.1.

[0033] With the above structure and workflow, this equipment can automatically complete printing and precise cutting of multi-level stepped structures with only one paper feed. It has a compact structure, high degree of automation and cutting accuracy, and can adapt to the processing needs of various sizes of stepped printing media. V. Description of the attached drawings
