Description

Technical Field

[0001] This utility model relates to the field of laser printer technology, specifically a carpet film laser printer. Background Technology

[0002] Personalized carpet pattern processing has a wide range of applications in high-end carpet customization, advertising signage, and exhibition paving. In particular, laser pattern marking on transparent or semi-transparent carpet film materials not only enables non-contact and rapid imaging, but also has the advantages of high positioning accuracy and low heat-affected zone. Therefore, laser printing has gradually replaced traditional inkjet printing and hot-press lamination methods.

[0003] In existing technologies, common carpet laser printing equipment mainly adopts a combination of a fixed laser head structure and an XY linear guide platform. This type of structure achieves pattern drawing on the carpet surface by driving the platform to move or the laser head to slide along the horizontal axis. However, this type of structure has the following limitations:

[0004] Limited working area and poor adjustment flexibility: Traditional linear slide rail structure is difficult to adapt to the continuous printing needs of ultra-large format carpet film, the equipment is bulky and inconvenient to move, and cannot meet the printing requirements of outdoor or temporary sites.

[0005] Low laser head positioning and adjustment accuracy: When facing uneven carpet surfaces or materials of different thicknesses, the laser head has poor vertical adjustment capability, which can easily cause focus shift and affect the clarity and consistency of the printed pattern.

[0006] High energy consumption and low integration: Traditional equipment has a complex drive structure, uneven power distribution, and lacks an integrated intelligent control unit, resulting in sluggish overall system response and affecting processing efficiency.

[0007] In addition, in some rotary printing mechanisms, the laser head often moves in an arc shape through an external arm, but lacks an efficient support and rotation guidance structure, resulting in poor stability, large vibration during operation, and difficulty in precision control, which is not conducive to continuous imaging of high-resolution patterns.

[0008] In summary, existing carpet film laser printing equipment has certain limitations in terms of structural compactness, path control precision, and ability to adapt to complex surfaces. There is an urgent need to develop a new type of laser printing device with a more optimized structure, more flexible motion path, and a wider adjustment range to meet the customized, intelligent, and high-precision development needs of modern carpet processing. Utility Model Content

[0009] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0010] Therefore, the technical solution adopted by this utility model is: a carpet film laser printer, including a mobile vehicle, a printer frame and a laser printer head;

[0011] A support frame is fixedly installed on the surface of the mobile vehicle body, and a support ring is fixedly installed on the surface of the support frame to support the rotating parts and form a rotation path. The printer frame is rotatably installed on the surface of the support ring. The printer frame includes a rotating ring seat, a vertical frame, and a lifting drive assembly fixed to the end of the vertical frame. The lifting drive assembly is used to drive the laser printer head to move up and down in the vertical direction. A pulley and a servo motor are provided inside the mobile vehicle body to drive the rotating ring seat to slide and rotate on the surface of the support ring. A battery pack and a mobile drive motor are fixedly installed inside the mobile vehicle body, and a mobile wheel is rotatably installed on its surface. The mobile wheel meshes with the output end of the mobile drive motor for transmission.

[0012] The mobile vehicle body has a built-in control component for controlling the coordinated operation of the mobile drive motor, servo motor, and laser printer head according to the laser printing pattern. The control component is equipped with an image data storage module and a path calculation unit, which are used to generate corresponding joint control signals for the servo motor, laser printer head, and mobile drive motor according to the preset pattern path. The servo motor is a high-precision servo motor with an encoder, which is used to realize closed-loop control of the rotation position of the rotating ring seat.

[0013] In a preferred example, a roller pin is rotatably mounted at the end of the support frame. The roller pin slides against the inner side of the rotating ring seat to achieve deflection guidance and improve rotational stability.

[0014] In a preferred example, the bearing ring surface is provided with a plurality of balls evenly distributed in a circumferential direction, the top surface of the balls slidingly abutting against the bottom surface of the swivel ring seat, which is used to reduce rotational friction and improve path smoothness.

[0015] In a preferred embodiment, the lifting drive assembly is a linear actuator structure arranged vertically to adjust the lifting height of the laser printer head to accommodate differences in carpet surface thickness; and the rotating base and the stand have built-in cables for the laser printer head, the lifting drive assembly, and the control assembly to ensure a compact and orderly wiring layout.

[0016] In a preferred example, the pulley is rotatably mounted inside the moving vehicle body, and the servo motor output end meshes with the surface of the pulley for transmission. The deflection drive of the rotating seat is achieved by a belt sleeved on the surface of the pulley and the rotating seat.

[0017] In a preferred example, the laser printer head is a dot matrix laser printing module with its axis located on the axis of the rotating seat to ensure printing accuracy and rotation synchronization.

[0018] The beneficial effects achieved by this utility model are as follows:

[0019] 1. In this utility model, by setting a support frame and a support ring on the mobile vehicle body, and rotating the printer frame onto the support ring via a rotating seat, combined with the internal linkage structure of pulleys, servo motors and mobile drive motors, dual control of the laser printer head on the circumferential path and the linear movement path is realized, so that the printed pattern can cover a larger area, effectively improving the printing efficiency and coverage accuracy of carpet film patterns, and enhancing the level of automation.

[0020] 2. In this utility model, a ring bearing and rotating seat are used in combination, which allows the laser printer head to rotate smoothly on its circumferential path. With the help of the servo motor drive pulley and transmission belt, high-precision rotation control is achieved. This avoids the problems of limited motion range, large platform size and complex guide rail maintenance in traditional linear guide rail path positioning structures, and improves the accuracy and stability of path control.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0030] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0031] The following describes, with reference to the accompanying drawings, some embodiments of a carpet film laser printer provided by this utility model.

[0032] Combination Figures 1-5 As shown, this utility model provides a carpet film laser printer, including a mobile carriage 100, a printer frame 200, and a laser printer head 300. A support frame 110 is fixedly mounted on the surface of the mobile carriage 100, and a support ring 120 is fixedly mounted on the surface of the support frame 110. The support ring 120 has a ring-shaped structure and is used to support the rotating structure of the printer frame 200. The printer frame 200 is rotatably mounted on the surface of the support ring 120 and includes a rotating seat 210, a vertical frame 220, and a lifting drive assembly 230 fixed to the end of the vertical frame 220. The lifting drive assembly 230 is used to drive the laser printer head 300 to adjust vertically, achieving focus control of carpet areas at different heights. The mobile carriage 100 has a pulley 130 and a servo motor 140 inside. The output end of the servo motor 140 is engaged with the pulley 130 to drive the pulley 130 to rotate. A transmission belt structure is provided between the pulley 130 and the rotating ring seat 210, which can drive the rotating ring seat 210 to achieve circumferential sliding deflection on the bearing ring 120. Through this structure, the laser print head 300 can achieve rotational adjustment along the circumferential path of the bearing ring 120.

[0033] like Figure 2 and Figure 5 As shown, a battery pack 102 and a mobile drive motor 103 are also fixedly installed inside the mobile vehicle body 100 to provide power and control for the entire device. The output end of the mobile drive motor 103 meshes with the mobile wheel 101 for transmission. The mobile wheel 101 is rotatably mounted on the surface of the mobile vehicle body 100 to drive the entire machine to move along the carpet surface.

[0034] The mobile vehicle body 100 also integrates a control component, which is used to receive printing path instructions and control the mobile drive motor 103, servo motor 140 and laser printer head 300 to work in coordination according to the set trajectory, so as to achieve high-precision printing output of laser patterns.

[0035] In this embodiment, a rotating roller pin 111 is rotatably mounted at the end of the support frame 110. The rotating roller pin 111 slides against the inner side of the rotating ring seat 210 to provide auxiliary guidance for the rotating ring seat 210 during rotation and improve its rotational stability.

[0036] In this embodiment, the surface of the bearing ring 120 is provided with a plurality of ball structures evenly distributed in a circumferential direction. The top surface of the ball slides against the bottom surface of the rotating ring seat 210 to reduce rotational resistance and enhance its rotational smoothness.

[0037] In this embodiment, the lifting drive assembly 230 is a linear actuator structure, vertically arranged, and has a push-pull output function. It is used to drive the laser print head 300 to adjust its height, adapting to the printing needs of carpet areas of different thicknesses. Preferably, the rotating base 210 and the upright frame 220 integrate cables for the laser print head 300, the lifting drive assembly 230, and the control components to ensure stable transmission of power and control signals.

[0038] In this embodiment, such as Figure 3 and Figure 4 As shown, pulley 130 is rotatably mounted on the inner side of the mobile vehicle body 100. The output end of the servo motor 140 meshes with the surface of pulley 130, thereby driving the belt-driven rotating ring seat 210 to deflect. Both the surface of pulley 130 and rotating ring seat 210 are fitted with transmission belts to achieve power transmission.

[0039] In this embodiment, the laser printer head 300 uses a laser beam to etch and print on the material surface. The axis of the laser printer head 300 is located on the axis of the rotating ring seat 210, which can realize high-precision laser pattern printing on the carpet film surface, ensuring printing clarity and consistency.

[0040] In this embodiment, the mobile vehicle body 100 is also provided with several auxiliary functional structures, including an image recognition unit, a positioning assistance module, and a laser rangefinder for path planning, which further enhances its recognition and control capabilities in complex carpet pattern areas.

[0041] With the cooperation of the above structures and the coordinated control of the control components, the laser print head 300 can achieve synchronization of multi-directional movement path and laser operation path, realizing accurate printing of continuous curved graphics or local patterns, which is particularly suitable for customized production of carpet patterns.

[0042] Working principle and usage process of this utility model:

[0043] The carpet film laser printer of this invention achieves laser pattern printing on carpet surface film through the linkage control between various modules within the mobile vehicle 100. Its working principle is as follows:

[0044] When the device is powered on, the control component first receives the printing path instruction and sends synchronous control instructions to the motion drive motor 103, servo motor 140 and laser printer head 300.

[0045] During execution: the mobile drive motor 103 drives the mobile wheel 101 to rotate through engagement, driving the mobile vehicle body 100 to move forward along the carpet surface; the servo motor 140 drives the pulley 130 to rotate, and through the transmission belt set between it and the rotating ring seat 210, realizes the deflection movement of the rotating ring seat 210, thereby driving the laser printer head 300 mounted on it to deflect and move along the trajectory of the bearing ring 120; the lifting drive assembly 230 drives the laser printer head 300 to adjust vertically up and down to adapt to different carpet surface thicknesses and focal height requirements; the rotating roller pin 111 set at the end of the support frame 110 slides against the inner side of the rotating ring seat 210, guiding its stable rotation; the surface of the bearing ring 120 is provided with several ball bearing fulcrums to support the sliding deflection of the rotating ring seat 210.

[0046] Under the coordination of the control system, the laser print head 300 moves in a circular direction while printing, and the moving carriage 100 moves forward synchronously, thereby realizing the printing output of large-format or continuous patterns. The entire printing path, laser control, and movement path are all coordinated and executed by the internal control components according to preset parameters.
